PART I


ITEM 1.	BUSINESS

Introduction

We are the largest regional theme park operator in the world based on the number of parks we operate. Of our 20 regional theme and waterparks, 17 are located in the United States, two are located in Mexico and one is located in Montreal, Canada. Our U.S. theme parks serve each of the top 10 designated market areas, as determined by a survey of television households within designated market areas published by A.C. Nielsen Media Research in September 2017. Our diversified portfolio of North American theme parks serves an aggregate population of approximately 100 million people and 175 million people within a radius of 50 miles and 100 miles, respectively, with some of the highest per capita gross domestic product in the U.S.

Our parks occupy approximately 4,600 acres of land, and we own approximately 800 acres of other potentially developable land. Our parks are located in geographically diverse markets across North America. Our parks generally offer a broad selection of state-of-the-art and traditional thrill rides, water attractions, themed areas, concerts and shows, restaurants, game venues and retail outlets, and thereby provide a complete family-oriented entertainment experience. In the aggregate, during 2017, our parks offered approximately 850 rides, including over 140 roller coasters, making us the leading provider of "thrill rides" in the industry.

In 1998, we acquired the former Six Flags Entertainment Corporation ("Former SFEC", a corporation that has been merged out of existence and that had always been a separate corporation from Holdings), which had operated regional theme parks under the Six Flags name for nearly forty years and established an internationally recognized brand name. We own the "Six Flags" brand name in the U.S. and foreign countries throughout the world. To capitalize on this name recognition, 17 of our parks are branded as "Six Flags" parks and, in 2014, we also began the development, with third-party partners, of Six Flags-branded theme parks outside of North America.

We hold exclusive long-term licenses for theme park usage of certain Warner Bros. and DC Comics characters throughout the U.S. (except the Las Vegas metropolitan area), Canada, Mexico and other countries. These characters include Bugs Bunny, Daffy Duck, Tweety Bird, Yosemite Sam, Batman, Superman, The Joker, Wonder Woman and others. We use these characters to market our parks and to provide an enhanced family entertainment experience. Our licenses include the right to sell merchandise featuring the characters at the parks, and to use the characters in our advertising, as walk-around characters and in theming for rides, attractions and retail outlets. We believe using these characters promotes increased attendance, supports higher ticket prices, increases lengths-of-stay and enhances in-park sales.

We believe that our parks benefit from limited direct theme park competition. A limited supply of real estate appropriate for theme park development, substantial initial capital investment requirements, long development lead-time, and zoning restrictions provide each of our parks with a significant degree of protection from competitive new theme park openings. Based on our knowledge of the development of our own and other regional theme parks, we estimate it would cost $400 million to $600 million and would take a minimum of three years to construct a new regional theme park comparable to one of our major Six Flags-branded theme parks.

Description of Parks and Segment Information

Our parks provide similar products and services through a similar process to the same class of customer through a consistent method. We also believe that our parks share common economic characteristics. Based on these factors, we have only one reportable segment—theme parks. The following chart summarizes key business and geographical information about our parks.

Partnership Park Arrangements

In connection with our 1998 acquisition of Former SFEC, we guaranteed certain obligations relating to Six Flags Over Texas ("SFOT") and Six Flags Over Georgia, including Six Flags White Water Atlanta ("SFOG", and together with SFOT, the "Partnership Parks"). These obligations continue until 2027, in the case of SFOG, and 2028, in the case of SFOT. Such obligations include (i) minimum annual distributions (including rent) of approximately $71.1 million in 2018 (subject to cost of living adjustments in subsequent years) to the limited partners in the Partnerships Parks (based on our ownership of units as of December 31, 2017, our share of the distribution will be approximately $31.1 million) and (ii) minimum capital expenditures at each park during rolling five-year periods based generally on 6% of Partnership Park revenues. Cash flow from operations at the Partnership Parks is used to satisfy these requirements first, before any funds are required from us. We also guaranteed the obligation of our subsidiaries to annually purchase all outstanding limited partnership units to the extent tendered by the unit holders (the "Partnership Park Put").

After payment of the minimum distribution, we are entitled to a management fee equal to 3% of prior year gross revenues and, thereafter, any additional cash will be distributed first to management fee in arrears, then repayment of any interest and principal on intercompany loans, with any additional cash being distributed 95% to us, in the case of SFOG, and 92.5% to us, in the case of SFOT.

The agreed price for units tendered in the Partnership Park Put is based on a valuation of each of the respective Partnership Parks (the "Specified Price") that is the greater of (i) a valuation for each of the respective Partnership Parks derived by multiplying such park's weighted average four year EBITDA (as defined in the agreements that govern the partnerships) by a specified multiple (8.0 in the case of SFOG and 8.5 in the case of SFOT) and (ii) a valuation derived from the highest prices previously paid for the units of the Partnership Parks by certain entities. Pursuant to the valuation methodologies described in the preceding sentence, the Specified Price for the Partnership Parks, if determined as of December 31, 2017, is $387.0 million in the case of SFOG and $485.2 million in the case of SFOT. As of December 31, 2017, we owned approximately 31.0% and 53.1% of the Georgia limited partner interests and Texas limited partner interests, respectively. The remaining redeemable units of approximately 69.0% and 46.9% of the Georgia limited partner and Texas limited partner, respectively, represent a current redemption value for the limited partnership units of approximately $494.4 million.

Pursuant to the 2017 annual offer, we did not purchase any units from the Georgia partnership and we purchased 0.0708 units from the Texas partnership for approximately $0.1 million in May 2017. With respect to the 2017 "put" obligations, no borrowing occurred. The $350 million accordion feature on the Amended and Restated Term Loan B under the Amended and Restated Credit Facility (as defined in "Management's Discussion and Analysis - Liquidity and Capital Resources of Financial Condition and Results of Operations" in Item 7 of this Annual Report) is available for borrowing for future "put" obligations if necessary.

In connection with our acquisition of the Former SFEC, we entered into the Subordinated Indemnity Agreement with certain of the Company's entities, Time Warner and an affiliate of Time Warner, pursuant to which, among other things, we transferred to Time Warner (which has guaranteed all of our obligations under the Partnership Park arrangements) record title to the corporations which own the entities that have purchased and will purchase limited partnership units of the Partnership Parks, we received an assignment from Time Warner of all cash flow received on such limited partnership units, and we otherwise control such entities. In addition, we issued preferred stock of the managing partner of the partnerships to Time Warner. In the event of a default by us under the Subordinated Indemnity Agreement or of our obligations to our partners in the Partnership Parks, these arrangements would permit Time Warner to take full control of both the entities that own limited partnership units and the managing partner. If we satisfy all such obligations, Time Warner is required to transfer to us the entire equity interests of these entities.

We incurred $24.7 million of capital expenditures at these parks during the 2017 season and intend to incur approximately $15.6 million of capital expenditures at these parks for the 2018 season, an amount in excess of the minimum required expenditure. Cash flows from operations at the Partnership Parks will be used to satisfy the annual distribution and capital expenditure requirements before any funds are required from us. The two partnerships generated approximately $77.3 million of cash in 2017 from operating activities after deduction of capital expenditures and excluding the impact of short-term intercompany advances from or payments to Holdings, as the case may be. As of December 31, 2017 and 2016, we had total loans receivable outstanding of $239.3 million from the partnerships that own the Partnership Parks. The proceeds from these loans were primarily used to fund the acquisition of Six Flags White Water Atlanta and to make capital improvements and distributions to the limited partners in prior years.

Marketing and Promotion

We attract visitors through multi-media marketing and promotional programs for each of our parks. The programs are designed to attract guests and enhance the Six Flags brand name, and are tailored to address the different characteristics of our various markets and to maximize the impact of specific park attractions and product introductions. All marketing and promotional programs are updated or completely changed each year to address new developments. These initiatives are supervised by our Senior Vice President, Marketing and Sales, with the assistance of our senior management and advertising and promotion agencies.

We also develop alliance, sponsorship and co-marketing relationships with well-known national, regional and local consumer goods companies and retailers to supplement our advertising efforts and to provide attendance incentives in the form of discounts. We also arrange for popular local radio and television programs to be filmed or broadcast live from our parks.

During 2013, we launched a monthly membership program. Season pass and membership sales establish an attendance base in advance of the season, reducing exposure to inclement weather and providing other benefits. In general, a season pass holder or member contributes higher aggregate revenue and profitability to the Company over the course of a year compared to a single day ticket guest because a season pass holder or member pays a higher ticket price and contributes to in-park guest spending over multiple visits. Additionally, guests enrolled in our membership program and season pass holders often bring paying guests and generate "word-of-mouth" advertising for the parks. During the 2017, 2016 and 2015 seasons, season pass and membership attendance constituted approximately 63%, 60% and 56%, respectively, of the total attendance at our parks.

At times we offer discounts on season passes, multi-visit tickets, tickets for specific dates and tickets to affiliated groups such as businesses, schools and religious, fraternal and similar organizations.

We also implement promotional programs as a means of targeting specific market segments and locations not generally reached through group or retail sales efforts. The promotional programs utilize coupons, sweepstakes, reward incentives and rebates to attract additional visitors. These programs are implemented through online promotions, direct mail, telemarketing, direct-response media, sponsorship marketing and targeted multi-media programs. The special promotional offers are usually for a limited time and offer a reduced admission price or provide some additional incentive to purchase a ticket.

Licenses

We have the exclusive right on a long-term basis to theme park usage of the Warner Bros. and DC Comics animated characters throughout the U.S. (except for the Las Vegas metropolitan area), Canada, Mexico and certain other countries. In particular, our license agreements entitle us to use, subject to customary approval rights of Warner Bros. and, in limited circumstances, approval rights of certain third parties, all animated, cartoon and comic book characters that Warner Bros. and DC Comics have the right to license, including Batman, The Joker, Superman, Wonder Woman, Bugs Bunny, Daffy Duck, Tweety Bird and Yosemite Sam, and include the right to sell merchandise using the characters. In addition to annual license fees, we are required to pay a royalty fee on merchandise manufactured by or for us and sold that uses the licensed characters. Warner Bros. has the right to terminate the license agreements under certain circumstances, including if any persons involved in the movie or television industries obtain control of us or, in the case of Warner Bros., upon a default under the Subordinated Indemnity Agreement.

Park Operations

We currently operate in geographically diverse markets in North America. The parks are generally managed by a park president who reports to a senior vice president of the Company. The park presidents are responsible for all operations and management of the individual parks. Local advertising, ticket sales, community relations and hiring and training of personnel are the responsibility of individual park management in coordination with corporate support teams.

Each park president directs a full-time, on-site management team. Each management team includes senior personnel responsible for operations and maintenance; in-park food, beverage, merchandising and games; marketing and promotion; sponsorships; human resources and finance. Finance directors at our parks report to a corporate senior vice president of the Company, and, with their support staff, provide financial services to their respective parks and park management teams. Park management compensation structures are designed to provide financial incentives for individual park managers to execute our strategy and to maximize revenue and free cash flow.

Our parks are generally open daily from Memorial Day through Labor Day. In addition, most of our parks are open weekends prior to and following their daily seasons, often in conjunction with themed events such as Fright Fest^® and Holiday in the Park^®. Due to their location, certain parks have longer operating seasons. Typically the parks charge a basic daily admission price that allows unlimited use of all rides and attractions, although in certain cases special rides and attractions require the payment of an additional fee. Beginning in January 2018, our Six Flags Magic Mountain park operates 365 days a year.

See Note 16 to the consolidated financial statements included elsewhere in this Annual Report for information concerning revenues and long-lived assets by domestic and international categories.

Capital Improvements and Other Initiatives

We regularly make capital investments, primarily for new rides and attractions in our parks, that total approximately 9% of revenues annually. We purchase both new and used rides and attractions. On occasion we also relocate rides among parks to provide fresh attractions. We believe that the selective introduction of new rides and attractions, including family entertainment attractions, is an important factor in promoting each of the parks to draw higher attendance and encourage longer visits, which can lead to higher in-park sales.

During 2017, we (i) added a 3D interactive dark ride at Six Flags Magic Mountain (Valencia, CA), Six Flags Great Adventure (Jackson, NJ), and Six Flags Over Georgia (Austell, GA); (ii) added a 4D free fly coaster at Six Flags Over Texas (Arlington, TX), Six Flags Great America (Gurnee, IL) and Six Flags New England (Agawam, MA); (iii) added a twenty-four story extreme swing ride at Six Flags America (outside Washington, D.C.); (iv) added a massive pendulum-shaped thrill ride at La Ronde (Montreal, Canada) and Six Flags Discovery Kingdom (Vallejo, CA); (v) introduced North America’s first rocket blast water coaster and a new Mardi Gras^® Festival special event at Six Flags Fiesta Texas (San Antonio, TX); (vi) introduced a five story spinning flat ride at Six Flags St. Louis (Eureka, MO); (vii) added dueling water body slides at The Great Escape and Splashwater Kingdom (Queensbury, NY); (viii) added a multi-dimensional virtual reality roller coaster as well as a new Mardi Gras^® Festival special event to Six Flags Mexico (Mexico City, Mexico); and (ix) introduced our nineteenth and twentieth parks, Six Flags Hurricane Harbor Oaxtepec (Oaxtepec, Mexico) and Waterworld California (Concord, California).

Planned initiatives for 2018 include (i) adding the world’s first single rail coaster at Six Flags Fiesta Texas (San Antonio, TX); (ii) adding the world’s tallest pendulum ride at Six Flags Magic Mountain (Valencia, CA); (iii) adding a first-of-its-kind in North America, triple box spinning ride at Six Flags Great Adventure (Jackson, NJ) and Six Flags Over Texas (Arlington, TX); (iv) debuting Twisted Cyclone, a hybrid roller coaster at Six Flags Over Georgia (Austell, GA); (v) adding a 70 miles-per-hour pendulum ride at Six Flags New England (Agawam, MA); (vi) adding a 4D Free Fly Coaster at Six Flags Mexico (Mexico City); (vii) debuting an adventure river at Six Flags America (Largo, MD); (viii) adding the world’s first-of-its-kind inverted coaster at Six Flags Discovery Kingdom (Vallejo, CA); (ix) adding the world’s largest loop coaster at Six Flags Great America (Gurnee, IL); (x) adding a hybrid, zero-gravity slide complex at Six Flags St. Louis (Eureka, MO); (xi) adding a classic spinning attraction at The Great Escape and Splashwater Kingdom (Queensbury, NY); (xii) adding a new family thrill ride at La Ronde (Montreal, Canada); and (xiii) debuting a new family interactive water play attraction at Waterworld (Concord, CA).

In addition to new rides and attractions, we make other capital improvements. We generally make capital investments in the food, retail, games and other in-park areas to increase per capita guest spending. We also make annual enhancements in the theming and landscaping of our parks in order to provide a more complete family-oriented entertainment experience. Each year we invest in our information technology infrastructure, which helps enhance our operational efficiencies. Maintenance capital expenditures are planned on an annual basis with most expenditures made during the off-season. Repairs and maintenance costs for materials and services associated with maintaining assets, such as painting and inspecting existing rides, are expensed as incurred and are not included in capital expenditures.

Also during 2018, we plan to continue (i) our targeted marketing strategies to attract guests, including focusing on our breadth of product and value offerings; (ii) improving and expanding upon our branded product offerings and guest-focused initiatives to continue driving guest spending growth, including new membership programs, as well as our all season dining pass program, which enables season pass holders and members to eat meals and snacks any day they visit the park for one upfront payment; and (iii) growing sponsorship and international revenue opportunities.

International Licensing

We have signed agreements to assist third parties in the development and management of Six Flags-branded theme parks outside of North America. As compensation for exclusivity, brand licensing rights, and design, development and management services, we receive fees during the design and development period as well as ongoing remuneration after the parks open to the public. The agreements do not require us to make any capital investments in the parks. We currently have agreements to develop Six Flags-branded parks in Dubai and China.

Maintenance and Inspection

Rides are inspected at various levels and frequencies in accordance with manufacturer specifications. Our rides are inspected daily during the operating season by our maintenance personnel. These inspections include safety checks, as well as regular maintenance, and are made through both visual inspection and test operations of the rides. Our senior management and the individual park personnel evaluate the risk aspects of each park's operations. Potential risks to employees and staff as well as to the public are evaluated. In addition, contingency response plans for potential emergency situations have been developed

Table of Contents

for each facility. During the off-season, maintenance personnel examine the rides and repair, refurbish and rebuild them where necessary. This process includes x-raying and magnafluxing (a further examination for minute cracks and defects) steel portions of certain rides at high-stress points. A large portion of our full-time workforce devote substantially all of their time to maintaining the parks and our rides and attractions. We use a computerized maintenance-management system across all of our domestic parks to assist us in executing our maintenance programs.

In addition to the performance of our internal maintenance and inspection procedures, third-party consultants are retained by us or our insurance carriers to perform an annual inspection of each park and all attractions and related maintenance procedures. The results of these inspections are reported in written evaluation and inspection reports and include suggestions on various aspects of park operations. In certain states, state inspectors conduct additional annual ride inspections before the beginning of each season. Other portions of each park are subject to inspections by local fire marshals and health and building department officials. Furthermore, we use Ellis & Associates as water safety consultants at all of our waterparks to train lifeguards and audit safety procedures.

Insurance

We maintain insurance of the types and in amounts that we believe are commercially reasonable and that are available to businesses in our industry. We maintain multi-layered general liability policies that provide for excess liability coverage of up to $100.0 million per occurrence. For incidents arising after November 15, 2003 but prior to December 31, 2008, our self-insured retention is $2.5 million per occurrence ($2.0 million per occurrence for the twelve months ended November 15, 2003 and $1.0 million per occurrence for the twelve months ended November 15, 2002) for our domestic parks and a nominal amount per occurrence for our international parks. For incidents arising after November 1, 2004 but prior to December 31, 2008, we have a one-time additional $0.5 million self-insured retention, in the aggregate, applicable to all claims in the policy year. For incidents arising on or after December 31, 2008, our self-insured retention is $2.0 million, followed by a $0.5 million deductible per occurrence applicable to all claims in the policy year for our domestic parks and our park in Canada and a nominal amount per occurrence for our parks in Mexico. Defense costs are in addition to these retentions. Our general liability policies cover the cost of punitive damages only in certain jurisdictions. Based upon reported claims and an estimate for incurred, but not reported claims, we accrue a liability for our self-insured retention contingencies. For workers' compensation claims arising after November 15, 2003, our deductible is $0.75 million ($0.5 million deductible for the period from November 15, 2001 to November 15, 2003). We also maintain fire and extended coverage, business interruption, terrorism and other forms of insurance typical to businesses in this industry. The all peril property coverage policies insure our real and personal properties (other than land) against physical damage resulting from a variety of hazards. Additionally, we maintain information security and privacy liability insurance in the amount of $10.0 million with a $0.25 million self-insured retention per event.

We generally renegotiate our insurance policies on an annual basis. The majority of our current insurance policies expire on December 31, 2018. We cannot predict the level of the premiums that we may be required to pay for subsequent insurance coverage, the level of any self-insurance retention applicable thereto, the level of aggregate coverage available or the availability of coverage for specific risks.

Competition

Our parks compete directly with other theme parks, water and amusement parks and indirectly with all other types of recreational facilities and forms of entertainment within their market areas, including movies, sporting events, home entertainment options, restaurants and vacation travel. Accordingly, our business is and will continue to be subject to factors affecting the recreation and leisure time industries generally, such as general economic conditions and changes in discretionary consumer spending habits. See "Item 1A. Risk Factors." Within each park's regional market area, the principal factors affecting direct theme park competition include location, price, the uniqueness and perceived safety and quality of the rides and attractions in a particular park, the atmosphere and cleanliness of a park and the quality of its food and entertainment.

Seasonality

Our operations are highly seasonal, with approximately 75% of park attendance and revenues occurring in the second and third calendar quarters of each year, with the most significant period falling between Memorial Day and Labor Day.

Environmental and Other Regulations

Our operations are subject to federal, state and local environmental laws and regulations including laws and regulations governing water and sewer discharges, air emissions, soil and groundwater contamination, the maintenance of underground and aboveground storage tanks and the disposal of waste and hazardous materials. In addition, our operations are subject to other local, state and federal governmental regulations including, without limitation, labor, health, safety, zoning and land use and minimum wage regulations applicable to theme park operations, and local and state regulations applicable to restaurant

Table of Contents

operations at each park. Finally, certain of our facilities are subject to laws and regulations relating to the care of animals. We believe that we are in substantial compliance with applicable environmental and other laws and regulations and, although no assurance can be given, we do not foresee the need for any significant expenditures in this area in the near future.

Portions of the undeveloped areas at certain of our parks are classified as wetlands. Accordingly, we may need to obtain governmental permits and other approvals prior to conducting development activities that affect these areas and future development may be prohibited in some or all of these areas. Additionally, the presence of wetlands in portions of our undeveloped land could adversely affect our ability to dispose of such land and/or the price we receive in any such disposition.

Philanthropy and Community Relations

We believe it is important to support the communities in which our parks are located. We partner with charitable organizations throughout North America whose mission aligns with our goal of bringing joy and thrills to families and children. Through our Read to Succeed program, we support academic achievement and seek to improve literacy by encouraging students to engage in recreational reading, and award free admission to eligible participants in the program. Most of our full-time employees spend at least an entire day each year volunteering on projects in their local communities to help others including distributing food to those in need, improving community centers and building or repairing homes. In addition, we sponsor toy drives, book drives, food drives and blood donation drives at our parks, and are committed to honoring the service of the U.S. military personnel and their families by offering complimentary and/or discounted admission to our parks. We also maintain a program in which we make a concerted effort to interview and hire U.S. military veterans. We also host special events to support various philanthropies whose mission focuses on improving health or supporting those affected by natural disasters.

Employees

As of December 31, 2017, we employed approximately 2,000 full-time employees, and over the course of the 2017 operating season we employed approximately 46,000 seasonal employees. In this regard, we compete with other local employers for qualified students and other candidates on a season-by-season basis. As part of the seasonal employment program, we employ a significant number of teenagers, which subjects us to child labor laws.

Approximately 17% of our full-time and approximately 10% of our seasonal employees are subject to labor agreements with local chapters of national unions. These labor agreements expire in December 2019 (Six Flags Over Georgia), December 2020 (Six Flags Magic Mountain), January 2021 (Six Flags Over Texas), and December 2021 (Six Flags Great Adventure). The labor agreements for La Ronde expire in various years ranging from December 2017 (currently under negotiation) through December 2022. We consider our employee relations to be good.

ITEM 1A.	RISK FACTORS

Set forth below are the principal risks that we believe are material to our business and should be considered by our security holders. We operate in a continually changing business environment and, therefore, new risks emerge from time to time. This section contains forward-looking statements. For an explanation of the qualifications and limitations on forward-looking statements, see "Cautionary Note Regarding Forward-Looking Statements."

Risks Relating to Our Business

General economic conditions throughout the world may have an adverse impact on our business, financial condition or results of operations.

Our success depends to a large extent on discretionary consumer spending, which is heavily influenced by general economic conditions and the availability of discretionary income. Difficult economic conditions and recessionary periods may have an adverse impact on our business and our financial condition. Negative economic conditions, coupled with high volatility and uncertainty as to the future global economic landscape, have at times had a negative effect on consumers' discretionary income and consumer confidence and similar impacts can be expected should such conditions recur. A decrease in discretionary spending due to decreases in consumer confidence in the economy or us, or a continued economic slowdown or deterioration in the economy, could adversely affect the frequency with which guests choose to visit our parks and the amount that our guests spend when they visit. The actual or perceived weakness in the economy could also lead to decreased spending by our guests. Both attendance and guest spending at our parks are key drivers of our revenue and profitability, and reductions in either could materially adversely affect our business, financial condition and results of operations.

Additionally, difficult economic conditions throughout the world could impact our ability to obtain supplies, services and credit as well as the ability of third parties to meet their obligations to us, including, for example, payment of claims by our insurance carriers, the funding of our lines of credit, or payment by our international licensing partners. Changes in exchange rates for foreign currencies could reduce international demand for our products, increase our labor and supply costs in non-U.S. markets or reduce the U.S. dollar value of revenue we earn in other markets.

Our growth strategy may not achieve the anticipated results.

Our future success will depend on our ability to grow our business, including through capital investments to improve existing parks, rides, attractions and shows, as well as in-park services and product offerings. Our business strategy for growth may also include selective expansion, both domestically and internationally, through acquisitions of assets or other strategic initiatives, such as licensing arrangements, joint ventures and partnerships that allow us to profitably expand our business and leverage our brand. Our growth and innovation strategies require significant commitments of management resources and capital investments and may not grow our revenues at the rate we expect or at all. Our business strategy for growth also requires the other parties to our licensing arrangements, joint ventures and partnerships to perform their obligations. The success of any acquisitions also depends on effective integration of acquired businesses and assets into our operations, which is subject to risks and uncertainties, including realization of anticipated synergies and cost savings, the ability to retain and attract personnel, the diversion of management's attention from other business concerns, and undisclosed or potential legal liabilities of acquired businesses or assets. As a result, we may not be able to recover the costs incurred in developing our new projects and initiatives or to realize their intended or projected benefits, which could materially adversely affect our business, financial condition or results of operations.

We may not obtain the desired improvements in operational and financial performance established in our aspirational goals, including those related to Project 600 and Project 750.

From time to time we establish aspirational goals for our operational and financial performance, including the "Project 600" goal established in 2014 to achieve Modified EBITDA of $600 million by 2017 and the "Project 750" goal established in 2016 to achieve Modified EBITDA of $750 million by 2020. We may seek to reach our aspirational goals through programs targeted at our key revenue drivers, marketing programs, pricing programs, operational changes and process improvements that are intended to increase revenue, reduce costs and improve our operational and financial performance. There is no assurance that these programs, changes and improvements will be successful or that we will achieve our aspirational goals in the timeframe in which we seek to achieve them or at all. Due to the adverse weather and natural disasters experienced during the

Table of Contents

summer months of 2017, the Company did not achieve the Project 600 goal. The Company believes late achievement of the Project 600 goal in 2018 is probable.

Bad or extreme weather conditions and forecasts of bad or mixed weather conditions can adversely impact attendance at our parks.

Because most of the attractions at our parks are outdoors, attendance at our parks is adversely affected by bad or extreme weather conditions and forecasts of bad or mixed weather conditions, which negatively affects our revenues. The effects of bad weather on attendance can be more pronounced at our waterparks. We believe that our operating results in certain years were adversely affected by abnormally hot, cold and/or wet weather in a number of our major U.S. markets. In addition, since a number of our parks are geographically concentrated in the eastern portion of the United States, a weather pattern that affects that area could adversely affect a number of our parks and disproportionately impact our results of operations. In addition, bad weather and forecasts of bad weather on weekends, holidays or other peak periods will typically have a greater negative impact on our revenues and could disproportionately impact our results of operations.

Natural disasters could adversely impact attendance at our parks and result in decreased revenues.

A severe natural disaster, such as an earthquake, hurricane, forest fire, flood or landslide, could interrupt our operations, damage our properties and reduce the number of guests who visit our parks in affected areas. Damage to our properties could take a long time to repair and there is no guarantee that we would have adequate insurance to cover the costs of repair or the expense of the interruption to our business. Furthermore, such a disaster may interrupt or impede access to our affected properties or require evacuations and may cause visits to our affected properties to decrease for an indefinite period. For example, our waterpark in Oaxtepec, Mexico was closed for several weeks during the fall of 2017 following the earthquakes in central Mexico. The occurrence of such natural disasters could have a material adverse effect on our business, financial condition and results of operations.

Local events and terrorist activities can adversely impact park attendance.

Lower attendance at our parks may be caused by various local activities that we may not be able to adequately anticipate or respond to. For example, terrorist alerts and threats of future terrorist activities may adversely affect attendance at our parks. In addition, since some of our parks are near major urban areas and appeal to teenagers and young adults, there may be disturbances at one or more parks that could negatively affect our image. This may result in a decrease in attendance at the affected parks and could adversely impact our results of operations. We cannot predict the frequency or severity of these activities and the effect that they may have on our business, financial condition or results of operations.

A significant disruption in our computer systems and our inability to adequately maintain and update those systems could adversely affect our operations and our ability to maintain guest confidence.

We rely extensively on our computer systems to manage and maintain the privacy of guest data and our financial and business data, summarize and analyze results, and manage and account for inventory. We require continued and unimpeded access to the Internet to use these computer systems. Our systems are subject to damage or interruption from power outages, telecommunications failures, computer viruses, malicious attacks, security breaches and catastrophic events. If our systems are damaged or fail to function properly or reliably, we may incur substantial repair or replacement costs, experience data loss or theft and impediments to our ability to manage inventories, engage in additional promotional activities to retain our guests, or encounter lost guest confidence, any of which could adversely affect our results of operations.

If our efforts to protect the security of information about our guests and employees and our internal data are unsuccessful, we may face costly litigation and our revenue and our reputation could suffer.

An important component of our business involves the receipt and storage of information about our guests as well as maintaining our internal business data. We have, and require certain of our vendors to have, programs in place to detect, contain and respond to data security incidents. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may be difficult to detect for long periods of time, we may be unable to anticipate these techniques or implement adequate preventive measures. In addition, hardware, software, or applications we develop or procure from third parties may contain defects in design or manufacture or other problems that could unexpectedly compromise information security. Unauthorized parties may also attempt to gain access to our systems or facilities, or those of third parties with whom we do business, through fraud, trickery, or other forms of deceiving our employees, contractors, and vendors. Like many other companies, from time to time, both we and our vendors have experienced data security incidents; however, to date, these incidents have not been material to our business, financial condition

or results of operations. If we or our vendors experience significant data security breaches or fail to detect and appropriately respond to significant data security breaches, we could be exposed to litigation, fines or other costs, our operations could be disrupted, and our guests could lose confidence in our ability to protect their information, which could cause them to stop purchasing our tickets, season passes or memberships from us or visiting our parks altogether.

Our operations are seasonal.

Our operations are seasonal. Approximately 75% of our annual park attendance and revenue occurs during the second and third calendar quarters of each year. As a result, when conditions or events described in the above risk factors occur during the operating season, particularly during the peak months of July and August, there is only a limited period of time during which the impact of those conditions or events can be mitigated. Accordingly, such conditions or events may have a disproportionately adverse effect on our revenues and cash flow. In addition, most of our expenses for maintenance and costs of adding new attractions are incurred when the parks are closed in the mid to late autumn and winter months. For this reason, a sequential quarter-to-quarter comparison is not a good indication of our performance or of how we will perform in the future.

There is a risk of accidents occurring at our parks or competing parks which may reduce attendance and negatively impact our operations.

Our brand and our reputation are among our most important assets. Our ability to attract and retain customers depends, in part, upon the external perceptions of the Company, the quality and safety of our parks, services and rides, and our corporate and management integrity. While we carefully maintain the safety of our rides, there are inherent risks involved with these attractions. An accident or an injury (including water-borne illnesses at waterparks) at any of our parks or at parks operated by competitors, particularly an accident or injury involving the safety of guests and employees, that receives media attention, could negatively impact our brand or reputation, cause loss of consumer confidence in the Company, reduce attendance at our parks, and negatively impact our results of operations. The considerable expansion in the use of social media over recent years has compounded the impact of negative publicity. If any such incident occurs during a time of high seasonal demand, the effect could disproportionately impact our results of operations for the year.

We depend on a seasonal workforce, many of whom are paid at minimum wage.

Our park operations are dependent in part on a seasonal workforce, many of whom are paid at minimum wage. We seek to manage seasonal wages and the timing of the hiring process to ensure the appropriate workforce is in place for peak and low seasons, however, we may be unable to recruit and hire sufficient personnel to meet our business needs. In addition, we cannot guarantee that material increases in the cost of securing our seasonal workforce will not occur in the future. Increased state or federal minimum wage requirements, seasonal wages or an inadequate workforce could have an adverse impact on our results of operations. We anticipate that the recent increases to the minimum wage rates will increase our salary, wage and benefit expenses in 2018 and future years and further legislative changes could continue to increase these expenses in the future.

The theme park industry competes with numerous entertainment alternatives and such competition may have an adverse impact on our business, financial condition or results of operations.

Our parks compete with other theme parks, waterparks and amusement parks and with other types of recreational facilities and forms of entertainment, including movies, home entertainment options, sporting events, restaurants and vacation travel. Our business is also subject to factors that affect the recreation and leisure time industries generally, such as general economic conditions, including relative fuel prices, and changes in consumer spending habits. The principal competitive factors of a park include location, price, the uniqueness and perceived quality of the rides and attractions, the atmosphere and cleanliness of the park and the quality of its food and entertainment. If we are unable to compete effectively against entertainment alternatives or on the basis of principal competitive factors of the park, our business, financial condition or results of operations may be adversely affected.

We could be adversely affected by changes in consumer tastes and preferences for entertainment and consumer products.

The success of our parks depends substantially on consumer tastes and preferences that can change in often unpredictable ways and on our ability to ensure that our parks meet the changing preferences of the broad consumer market. We conduct research and analysis before acquiring new parks or opening new rides or attractions and often invest substantial amounts before we learn the extent to which these new parks and new rides or attractions will earn consumer acceptance. If visitor volumes at our parks were to decline significantly or if new rides and entertainment offerings at our parks do not achieve sufficient consumer acceptance, revenues and margins may decline. Our results of operations may also be adversely affected if we fail to retain long-term customer loyalty or provide satisfactory customer service.

Our insurance coverage may not be adequate to cover all possible losses that we could suffer and our insurance costs may increase.

Although we maintain various safety and loss prevention programs and carry property and casualty insurance to cover certain risks, our insurance policies do not cover all types of losses and liabilities. Additionally, there can be no assurance that our insurance will be sufficient to cover the full extent of all losses or liabilities for which we are insured. The majority of our current insurance policies have annual terms and expire on December 31, 2018, and we cannot guarantee that we will be able to renew our current insurance policies on favorable terms, or at all. In addition, if we or other theme park operators sustain significant losses or make significant insurance claims, then our ability to obtain future insurance coverage at commercially reasonable rates could be materially adversely affected. If our insurance coverage is not adequate, or we become subject to damages that cannot by law be insured against, such as punitive damages or certain intentional misconduct by our employees, this could adversely affect our financial condition or results of operations.

If we are not able to fund capital expenditures and invest in future attractions and projects in our parks, our revenues could be negatively impacted.

Because a principal competitive factor for a theme park is the uniqueness and perceived quality of its rides and attractions, we need to make continued capital investments through maintenance and the regular addition of new rides and attractions. A key element for our revenue growth is strategic capital spending on such investments. Our ability to fund capital expenditures will depend on our ability to generate sufficient cash flow from operations and to raise capital from third parties. We cannot provide assurance that our operations will be able to generate sufficient cash flow to fund such costs, or that we will be able to obtain sufficient financing on adequate terms, or at all, which could cause us to delay or abandon certain projects or plans. In addition, any construction delays or ride downtime can adversely affect our attendance and our ability to realize revenue growth.

Product recalls, product liability claims and associated costs could adversely affect our reputation and our financial condition.

We sell food, toys and other retail products, the sale of which involves legal and other risks. We may need to recall food products if they become contaminated, and we may need to recall toys, games or other retail merchandise if there is a design or product defect. Even though we are resellers of food, toys and other retail products, we may be liable if the consumption or purchase of any of the products we sell causes illness or injury. A recall could result in losses due to the cost of the recall, the destruction of product and lost sales due to the unavailability of product for a period of time. A significant food or retail product recall could also result in adverse publicity, damage to our reputation and loss of consumer confidence in our parks, which could have a material adverse effect on our business, financial condition or results of operations.

We may be unable to purchase or contract with third parties to manufacture theme park rides and attractions.

We may be unable to purchase or contract with third parties to build high quality rides and attractions and to continue to service and maintain those rides and attractions at competitive or beneficial prices, or to provide the replacement parts needed to maintain the operation of such rides. In addition, if our third-party suppliers' financial condition deteriorates or they go out of business, we may not be able to obtain the full benefit of manufacturer warranties or indemnities typically contained in our contracts, or may need to incur greater costs for the maintenance, repair, replacement or insurance of these assets.

Adverse litigation judgments or settlements resulting from legal proceedings in which we may be involved in the normal course of our business could adversely affect our financial condition or results of operations.

We are subject to allegations, claims and legal actions arising in the ordinary course of our business, which may include claims by third parties, including guests who visit our parks, our employees or regulators. The outcome of these proceedings cannot be predicted. If any of these proceedings is determined adversely to us, or if we receive a judgment, a fine or a settlement involving a payment of a material sum of money, or injunctive relief is issued against us, our business, financial condition and results of operations could be materially adversely affected. Litigation can also be expensive, lengthy and disruptive to normal business operations, including to our management due to the increased time and resources required to respond to and address the litigation.

Additionally, from time to time, animal activist and other third-party groups may make negative public statements about us or bring claims before government agencies or lawsuits against us. Such claims and lawsuits sometimes are based on allegations that we do not properly care for some of our featured animals. On other occasions, such claims and/or lawsuits are specifically designed to change existing law or enact new law in order to impede our ability to retain, exhibit, acquire or breed animals. While we seek to comply with all applicable federal and state laws and vigorously defend ourselves in any lawsuits,

Table of Contents

there are no assurances as to the outcome of future claims and lawsuits that could be brought against us. An unfavorable outcome in any legal proceeding could have a material adverse effect on our business, financial condition and results of operations. In addition, associated negative publicity could adversely affect our reputation, financial condition and results of operations.

Our leases contain default provisions that, if enforced or exercised by the landlord, could significantly impact our operations at those parks.

Certain of our leases permit the landlord to terminate the lease if there is a default under the lease, including, for example, our failure to pay rent, utilities and applicable taxes in a timely fashion or to maintain certain insurance. If a landlord were to terminate a lease, it would halt our operations at that park and, depending on the size of the park, could have a negative impact on our financial condition and results of operations. In addition, any disputes that may result from such a termination may be expensive to pursue and may divert money and management's attention from our other operations and adversely affect our business, financial condition or results of operations.

Our intellectual property rights are valuable, and any inability to protect them could adversely affect our business.

Our intellectual property, including our trademarks and domain names and other proprietary rights, constitutes a significant part of our value. To protect our intellectual property rights, we rely upon a combination of trademark, trade secret and unfair competition laws of the United States and other countries, as well as contract provisions and third-party policies and procedures governing internet/domain name registrations. However, there can be no assurance that these measures will be successful in any given case, particularly in those countries where the laws do not protect our proprietary rights as fully as in the United States. We may be unable to prevent the misappropriation, infringement or violation of our intellectual property rights, breach of any contractual obligations to us, or independent development of intellectual property that is similar to ours, any of which could reduce or eliminate any competitive advantage we have developed, adversely affect our revenues or otherwise harm our business.

We may be subject to claims for infringing the intellectual property rights of others, which could be costly and result in the loss of intellectual property rights.

We cannot be certain that we do not and will not infringe the intellectual property rights of others. We have been in the past, and may be in the future, subject to litigation and other claims in the ordinary course of our business based on allegations of infringement or other violations of the intellectual property rights of others. Regardless of their merits, intellectual property claims can divert the efforts of our personnel and are often time-consuming and expensive to litigate or settle. In addition, to the extent claims against us are successful, we may have to pay substantial monetary damages or discontinue, modify, or rename certain products or services that are found to be in violation of another party's rights. We may have to seek a license (if available on acceptable terms, or at all) to continue offering products and services, which may increase our operating expenses.

Increased labor costs and employee health and welfare benefits may reduce our results of operations.

Labor is a primary component in the cost of operating our business. We devote significant resources to recruiting and training our managers and employees. Increased labor costs due to competition, increased minimum wage or employee benefit costs or otherwise, would adversely impact our operating expenses. The Patient Protection and Affordable Care Act of 2010 and the amendments thereto contain provisions which will impact our future healthcare costs. We do not anticipate these changes will result in a material increase in our operating costs. Our results of operations are also substantially affected by costs of retirement, including as a result of macro-economic factors beyond our control, such as declines in investment returns on pension plan assets and changes in discount rates used to calculate pension and related liabilities.

Additionally, we contribute to multiple defined benefit multiemployer pension plans on behalf of our collectively bargained employees of Six Flags Great Adventure LLC. If we were to cease contributing to or otherwise incur a withdrawal from any such plans, we could be obligated to pay withdrawal liability assessments based on the underfunded status (if any) of such plans at the time of the withdrawal. The amount of any multiemployer pension plan underfunding can fluctuate from year to year, and thus there is a possibility that the amount of withdrawal liability that we could incur in the future could be material, which could materially adversely affect our financial condition.

Unionization activities or labor disputes may disrupt our operations and affect our profitability.

As of December 31, 2017, approximately 17% of our full-time and approximately 10% of our seasonal employees were subject to labor agreements with local chapters of national unions. We have collective bargaining agreements in place for certain employees at Six Flags Over Georgia, Six Flags Magic Mountain, Six Flags Great Adventure, Six Flags Over Texas, Six

Table of Contents

Flags St. Louis, and La Ronde. New unionization activity or a labor dispute involving our employees could disrupt our operations and reduce our revenues, and resolution of unionization activities or labor disputes could increase our costs. Litigation relating to employment and/or wage and hour disputes could also increase our operating expenses. Such disrupted operations, reduced revenues or increased costs could have a material adverse effect on our financial condition and results of operations.

Our operations and our ownership of property subject us to environmental, health and safety and other regulations, which create uncertainty regarding future expenditures and liabilities.

Our operations involve wastewater and stormwater discharges and air emissions, and as a result are subject to environmental, health and safety laws, regulations and permitting requirements. These requirements are administered by the U.S. Environmental Protection Agency and the states and localities where our parks are located (and can also often be enforced through citizen suit provisions), and include the requirements of the Clean Water Act and the Clean Air Act. Our operations also involve maintaining underground and aboveground storage tanks, and managing and disposing of hazardous substances, chemicals and materials and are subject to federal, state and local laws and regulations regarding the use, generation, manufacture, storage, handling and disposal of these substances, chemicals and materials, including the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"). A portion of our capital expenditures budget is intended to ensure continued compliance with environmental, health and safety laws, regulations and permitting requirements. In the event of contamination or injury as a result of a release of or exposure to regulated materials, we could be held liable for any resulting damages. For example, pursuant to CERCLA, past and current owners and operators of facilities and persons arranging for disposal of hazardous substances may be held strictly, jointly and severally liable for costs to remediate releases and threatened releases of hazardous substances. The costs of investigation, remediation or removal of regulated materials may be substantial, and the presence of those substances, or the failure to remediate property properly, may impair our ability to use, transfer or obtain financing regarding our property. Our activities may be affected by new legislation or changes in existing environmental, health and safety laws. For example, the state or federal government having jurisdiction over a given area may enact legislation and the U.S. Environmental Protection Agency or applicable state entity may propose new regulations or change existing regulations that could require our parks to reduce certain emissions or discharges. Such action could require our parks to install costly equipment or increase operating expenses. We may be required to incur costs to remediate potential environmental hazards, mitigate environmental risks in the future, or comply with other environmental requirements.

We also are subject to federal and state laws, which prohibit discrimination and other laws regulating the design and operation of facilities, such as the Americans With Disabilities Act. Compliance with these laws and regulations can be costly and increase our exposure to litigation and governmental proceedings, and a failure or perceived failure to comply with these laws could result in negative publicity that could harm our reputation, which could adversely affect our business.

We may not be able to attract and retain key management and other key employees.

Our employees, particularly our key management, are vital to our success and difficult to replace. We may be unable to retain them or to attract other highly qualified employees, particularly if we do not offer employment terms competitive with the rest of the market. Failure to attract and retain highly qualified employees, or failure to develop and implement a viable succession plan, could result in inadequate depth of institutional knowledge or skill sets, adversely affecting our business.

We may not be able to realize the benefits of our international licensing agreements.

Various external factors, including difficult economic and political conditions throughout the world, could negatively affect the progress of our initiatives to develop new Six Flags-branded theme parks outside of North America. These initiatives could be delayed and the ultimate success of such parks may be uncertain. Some factors that will be important to the success of our international licensing initiatives are different than those affecting our existing parks. Tastes naturally vary by region, and consumers in new international markets into which we expand our brand may not embrace the parks’ offerings to the same extent as consumers in our existing markets. International licensing transactions are also subject to additional risks, including the performance of our partners and their ability to obtain financing; the impact of economic fluctuations in economies outside of the U.S.; difficulties and costs of staffing and managing foreign operations due to distance, language and cultural differences; changes or uncertainties in economic, legal, regulatory, social and political conditions; the enforceability of intellectual property and contract rights; and foreign currency exchange rate fluctuations, currency controls, and potentially adverse tax consequences of overseas operations. If we do not realize the benefits of such transactions, it could have an adverse effect on our financial performance.

Risks Related to Our Indebtedness and Common Stock

A portion of our cash flow is required to be used to fund our substantial monetary obligations.

We must satisfy the following obligations with respect to the Partnership Parks:


•	We must make annual distributions to our partners in the Partnership Parks, which will amount to approximately $71.1 million in 2018 (based on our ownership of units as of December 31, 2017, our share of the distribution will be approximately $31.1 million), with similar amounts (adjusted for changes in cost of living) payable in future years.


•	We must spend a minimum of approximately 6% of each of the Partnership Parks' annual revenues over specified periods for capital expenditures.

•

Each year we must offer to purchase all outstanding limited partnership units from our partners in the Partnership Parks. The remaining redeemable units of the Georgia limited partner and Texas limited partner, respectively, represent a current redemption value for the limited partnership units of approximately $494.4 million as of December 31, 2017. As we purchase additional units, we are entitled to a proportionate increase in our share of the minimum annual distributions. In future years, we may need to incur indebtedness under the Amended and Restated Credit Facility to satisfy such unit purchase obligations.

We expect to use cash flow from the operations at the Partnership Parks to satisfy all or part of our annual distribution and capital expenditure obligations with respect to these parks before we use any of our other funds. The two partnerships generated approximately $77.3 million of cash in 2017 from operating activities after deduction of capital expenditures and excluding the impact of short-term intercompany advances from or repayments to us. As of December 31, 2017, we had loans outstanding of $239.3 million to the partnerships that own the Partnership Parks, primarily to fund the acquisition of Six Flags White Water Atlanta, working capital in prior years and capital improvements. The obligations relating to SFOG continue until 2027 and those relating to SFOT continue until 2028. In the event of a default by us under the Subordinated Indemnity Agreement or of our obligations to our partners in the Partnership Parks, these arrangements would permit Time Warner to take full control of both the entities that own limited partnership units and the managing partner, and we would lose control of the Partnership Parks. In addition, such a default could trigger an event of default under the Amended and Restated Credit Facility. For more information regarding the Subordinated Indemnity Agreement, see "Business—Partnership Park Arrangements."

The vast majority of our capital expenditures in 2018 and beyond will be made on a discretionary basis, although such expenditures are important to the parks' ability to sustain and grow revenues. We spent $134.7 million on capital expenditures, net of property insurance recoveries, for all of our continuing operations in the 2017 calendar year. Our business plan includes targeted annual capital spending of approximately 9% of revenues in 2018. We may not, however, achieve our targeted rate of capital spending, which may cause us to spend in excess of, or less than, our anticipated rate.

Our indebtedness under the Amended and Restated Credit Facility and our other obligations could have material negative consequences to us and investors in our securities. The following could materially adversely affect our business, financial condition or results of operations:


•	We may not be able to satisfy all of our obligations, including, but not limited to, our obligations under the instruments governing our outstanding debt, which may cause a cross-default or cross-acceleration on other debt we may have incurred.


•	We could have difficulties obtaining necessary financing in the future for working capital, capital expenditures, debt service requirements, refinancing or other purposes.


•	We could have difficulties obtaining additional financing to fund our annual Partnership Park obligations if the amount of the Amended and Restated Credit Facility is insufficient.


•	We would have to use a significant portion of our cash flow to make payments on our debt and to satisfy the other obligations set forth above, which may reduce the capital available for operations and expansion.


•	Adverse economic or industry conditions may have a more negative impact on us.

We cannot be sure that cash generated from our parks will be as high as we expect or that our expenses will not be higher than we expect. Because a portion of our expenses are fixed in any given year, our operating cash flows are highly dependent on revenues, which are largely driven by attendance levels, in-park sales, accommodations and sponsorship and licensing activity. A lower amount of cash generated from our parks or higher expenses than expected, when coupled with our debt obligations, could adversely affect our ability to fund our operations.

Table of Contents

The instruments governing our indebtedness include financial and other covenants that will impose restrictions on our financial and business operations.

The instruments governing our indebtedness restrict our ability to, among other things, incur additional indebtedness, incur liens, make investments, sell assets, pay dividends, repurchase stock or engage in transactions with affiliates. In addition, the Amended and Restated Credit Facility contains financial covenants that will require us to maintain a minimum interest coverage ratio and a maximum senior secured leverage ratio. These covenants may have a material impact on our operations. If we fail to comply with the covenants in the Amended and Restated Credit Facility or the indenture governing Holdings' $300.0 million of 4.875% senior unsecured notes due July 31, 2024 (the "2024 Notes"), $700.0 million of 4.875% senior unsecured notes due 2024 (the "2024 Notes Add-on"), and $500.0 million of 5.50% senior unsecured notes due 2027 (the "2027 Notes") and are unable to obtain a waiver or amendment, an event of default would result under the applicable debt instrument.

Events beyond our control, such as weather and economic, financial and industry conditions, may affect our ability to continue meeting our financial covenant ratios under the Amended and Restated Credit Facility. The need to comply with these financial covenants and restrictions could limit our ability to execute our strategy and expand our business or prevent us from borrowing more money when necessary.

The Amended and Restated Credit Facility and the indentures governing the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes also contain other events of default customary for financings of these types, including cross defaults to certain other indebtedness, cross acceleration to other indebtedness and certain change of control events. If an event of default were to occur, the lenders under the Amended and Restated Credit Facility could declare outstanding borrowings under the Amended and Restated Credit Facility immediately due and payable and the holders of the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes could elect to declare the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes to be due and payable, together with accrued and unpaid interest. We cannot provide assurance that we would have sufficient liquidity to repay or refinance such indebtedness if it was accelerated upon an event of default. In addition, an event of default or declaration of acceleration under the Amended and Restated Credit Facility could also result in an event of default under other indebtedness.

We can make no assurances that we will be able to comply with these restrictions in the future or that our compliance would not cause us to forego opportunities that might otherwise be beneficial to us.

We may be unable to service our indebtedness.

Our ability to make scheduled payments on and to refinance our debt, including the Amended and Restated Credit Facility and the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes, depends on and is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business and other factors beyond our control, including the availability of financing in the banking and capital markets. We cannot provide assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to service our debt, to refinance our debt or to fund our other liquidity needs. If we are unable to meet our debt obligations or to fund our other liquidity needs, we may be forced to reduce or delay scheduled expansion and capital expenditures, sell material assets or operations, obtain additional capital or restructure our debt, which could cause us to default on our debt obligations and impair our liquidity. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. If we are required to dispose of material assets or operations or restructure our debt to meet our debt service and other obligations, we cannot provide assurance that the terms of any such transaction will be satisfactory to us or if, or how soon, any such transaction could be completed.

The market price of Holdings' common stock may be volatile, which could cause the value of an investment in Holdings' common stock to decline.

We can give no assurances about future liquidity in the trading market for Holdings' common stock. If there is limited liquidity in the trading market for Holdings' common stock, a sale of a large number of shares of Holdings' common stock could be adversely disruptive to the market price of Holdings' common stock.

Numerous factors, including many over which we have no control, may have a significant impact on the market price of Holdings' common stock. These risks include those described or referred to in this "Risk Factors" section and in other documents incorporated herein by reference as well as, among other things:


•	Our operating and financial performance and prospects;


•	Our ability to repay our debt;


•	Our access to financial and capital markets to refinance our debt or replace the existing credit facilities;


•	Investor perceptions of us and the industry and markets in which we operate;

Table of Contents


•	Our dividend policy;


•	Our stock repurchase program;


•	Future sales of equity or equity-related securities;


•	Changes in earnings estimates or buy/sell recommendations by analysts; and


•	General financial, domestic, economic and other market conditions.

Changes in our credit ratings could adversely affect the price of Holdings' common stock.

We receive debt ratings from the major credit rating agencies in the United States. Factors that may impact our credit ratings include the sizable attendance and revenue generated from our portfolio of geographically diversified regional theme parks, vulnerability to cyclical discretionary consumer spending, and seasonality of our operations. In March 2017, in connection with the issuance of the 2027 Notes, Moody's assigned a B2 rating to the 2027 Notes, upgraded the 2024 Notes from B3 to B2, and reaffirmed our Ba1 rating on the credit facility and our B1 corporate family rating. In March 2017, Standard & Poor's assigned a BB- rating to the 2027 Notes, and reaffirmed our BB- rating on the 2024 Notes and our BB corporate credit rating. Both rating agencies have placed our ratings on "stable outlook." We cannot provide assurance that our ratings will remain the same. A negative change in our ratings or the perception that such a change might occur could adversely affect the market price of Holdings' common stock.

Various factors could affect Holdings' ability to sustain its dividend.

Holdings' ability to pay a dividend on its common stock or sustain it at current levels is subject to our ability to generate sufficient cash flow to pay dividends. In addition, our debt agreements contain certain limitations on the amount of cash we are permitted to distribute to our stockholders by way of dividend or stock repurchase.

Holdings is a holding company and is dependent on dividends and other distributions from its subsidiaries.

Holdings is a holding company and substantially all of its operations are conducted through direct and indirect subsidiaries. As a holding company, it has no significant assets other than its equity interests in its subsidiaries. Accordingly, Holdings is dependent on dividends and other distributions from its subsidiaries to meet its obligations including the obligations under the Amended and Restated Credit Facility, the 2024 Notes, the 2024 Notes Add-on, and the 2027 Notes, and to pay the dividend on Holdings' common stock. If these dividends and other distributions are not sufficient for Holdings to meets its financial obligations, or not available to Holdings due to restrictions in the instruments governing our indebtedness, it could cause Holdings to default on our debt obligations, which would impair our liquidity and adversely affect our financial condition and our business. We had $77.5 million of cash and cash equivalents on a consolidated basis at December 31, 2017, of which $18.0 million was held at Holdings.

Provisions in Holdings' corporate documents and the law of the State of Delaware as well as change of control provisions in certain of our debt and other agreements could delay or prevent a change of control, even if that change would be beneficial to stockholders or could have a materially negative impact on our business.

Certain provisions in Holdings' Restated Certificate of Incorporation, the Amended and Restated Credit Facility and the indentures governing the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes may have the effect of deterring transactions involving a change in control of us, including transactions in which stockholders might receive a premium for their shares.

Holdings' Certificate of Incorporation provides for the issuance of up to 5,000,000 shares of preferred stock with such designations, rights and preferences as may be determined from time to time by Holdings' Board of Directors. The authorization of preferred shares empowers Holdings' Board of Directors, without further stockholder approval, to issue preferred shares with dividend, liquidation, conversion, voting or other rights that could adversely affect the voting power or other rights of the holders of the common stock. If issued, the preferred stock could also dilute the holders of Holdings' common stock and could be used to discourage, delay or prevent a change of control of us.

Holdings is also subject to the anti-takeover provisions of the Delaware General Corporation Law, which could have the effect of delaying or preventing a change of control in some circumstances. All of the foregoing factors could materially adversely affect the price of Holdings' common stock.

The Amended and Restated Credit Facility contains provisions pursuant to which it is an event of default if any "person" becomes the beneficial owner of more than 35% of the common stock. This could deter certain parties from seeking to acquire us and if any "person" were to become the beneficial owner of more than 35% of the common stock, we may not be able to repay such indebtedness.

Table of Contents

We have the exclusive right to use certain Warner Bros. and DC Comics characters in our theme parks in the U.S. (except in the Las Vegas metropolitan area), Canada, Mexico and certain other countries. Warner Bros. can terminate these licenses under certain circumstances, including the acquisition of us by persons engaged in the movie or television industries. This could deter certain parties from seeking to acquire us.

ITEM 3.	LEGAL PROCEEDINGS

The nature of the industry in which we operate tends to expose us to claims by guests, generally for injuries. Accordingly, we are party to various legal actions arising in the normal course of business, including the proceedings discussed below.

On January 7, 2016, a potential class action complaint was filed against Six Flags Entertainment Corporation in the Circuit Court of Lake County, Illinois. On April 22, 2016, Great America, LLC was added as a defendant. The complaint asserts that we violated the Illinois Biometric Information Privacy Act ("BIPA") in connection with the admission of season pass holders and members through the finger scan program at Six Flags Great America in Gurnee, Illinois, and seeks statutory damages, attorneys' fees and an injunction. An aggrieved party under BIPA may recover (i) $1,000 if a company is found to have negligently violated BIPA or (ii) $5,000 if found to have intentionally or recklessly violated BIPA, plus reasonable

attorneys' fees in each case. The program commenced at the park in the 2014 operating season. The complaint does not allege that any information was misused or disseminated. On April 7, 2017, the court certified two questions for consideration by the Illinois Appellate Court of the Second District. On June 7, 2017, the Illinois Appellate Court granted our motion to appeal. Accordingly, two questions regarding the interpretation of BIPA were certified for consideration by the Appellate Court. On December 21, 2017, the Appellate Court found in our favor, holding that the plaintiff had to allege more than a technical violation of BIPA and had to be injured in some way. We expect that the plaintiff will be filing a petition for leave to appeal to the Illinois Supreme Court by March 1, 2018. We intend to continue to vigorously defend ourselves against this litigation. Since this litigation is still in an early stage, the outcome is currently not determinable and a reasonable estimate of loss or range of loss in excess of the immaterial amount that we have recorded for this litigation cannot be made.

During 2017, four potential class action complaints were filed against Six Flags Entertainment Corporation or one of its subsidiaries. Complaints were filed on August 11, 2017 in the Circuit Court of Lake County, Illinois, on September 1, 2017 in the United States District Court for the Northern District of Georgia, on September 11, 2017 in the Superior Court of Los Angeles County, California, and on November 30, 2017 in the Superior Court of Ocean County, New Jersey. The complaints allege that we, in violation of federal law, printed more than the last five digits of a credit or debit card number on customers’ receipts, and/or the expiration dates of those cards. A willful violation may subject a company to liability for actual damages or statutory damages between $100 and $1,000 per person, punitive damages in an amount determined by a court, and reasonable attorneys’ fees, all of which are sought by the plaintiffs. The complaints do not allege that any information was misused. We intend to vigorously defend ourselves against this litigation. Since this litigation is in an early stage, the outcome is currently not determinable and a reasonable estimate of loss or range of loss cannot be made.

We are party to various other legal actions, including intellectual property disputes and employment and/or wage and hour litigation, arising in the normal course of business. We do not expect to incur any material liability by reason of such actions.

ITEM 5.	MARKET FOR THE REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information

Holdings' common stock trades on the New York Stock Exchange under the symbol "SIX."

On May 5, 2011 and May 8, 2013, Holdings' Board of Directors approved two-for-one stock splits of Holdings' common stock effective in the form of a stock dividend of one share of common stock for each outstanding share of common stock. The record dates for the stock splits were June 15, 2011 and June 12, 2013, respectively. The additional shares of common stock in connection with the stock splits were distributed on June 27, 2011 and June 26, 2013, respectively. In accordance with the provisions of our stock benefit plans and as determined by Holdings' Board of Directors, the number of shares available for issuance, the number of shares subject to outstanding equity awards and the exercise prices of outstanding stock option awards were adjusted to equitably reflect the effect of these two-for-one stock splits. All share and per share amounts presented in this Annual Report have been retroactively adjusted to reflect these stock splits.

Holders of Record

As of February 15, 2018, there were approximately 52 stockholders of record of Holdings' common stock. This does not reflect holders who beneficially own common stock held in nominee or street name.

Quarterly Dividends

In November 2017, Holdings' Board of Directors increased the quarterly cash dividend from $0.64 per share of common stock to $0.70 per share of common stock. In February 2018, Holdings' Board of Directors increased the quarterly cash dividend from $0.70 per share of common stock to $0.78 per share of common stock.

The amount and timing of any future dividends payable on Holdings' common stock are within the sole discretion of Holdings' Board of Directors. Holdings' Board of Directors currently anticipates continuing to pay cash dividends on Holdings' common stock on a quarterly basis. However, the declaration and amount of any future dividends depend on various factors including the Company's earnings, cash flows, financial condition and other factors. Furthermore, the Amended and Restated Credit Facility and the indentures governing the 2024 Notes, the 2024 Notes Add-on and the 2027 Notes include certain limitations on Holdings' ability to pay dividends. For more information, see "Management's Discussion and Analysis — Liquidity and Capital Resources of Financial Condition and Results of Operations" in Item 7 of this Annual Report and Note 7 to the consolidated financial statements in Item 8 of this Annual Report.

Issuer Purchases of Equity Securities

On November 20, 2013, Holdings announced that its Board of Directors approved a new stock repurchase program that permitted Holdings to repurchase up to $500.0 million in shares of Holdings' common stock over a four-year period (the "November 2013 Stock Repurchase Plan"). Holdings fully utilized the availability under the November 2013 Stock Repurchase Plan in August 2016. Throughout the program, Holdings repurchased 11,428,000 shares at a cumulative cost of approximately $500.0 million and an average price per share of $43.75.

On June 7, 2016, Holdings announced that its Board of Directors approved a new stock repurchase program that permits Holdings to repurchase an incremental $500.0 million in shares of Holdings' common stock (the "June 2016 Stock Repurchase Plan"). Holdings fully utilized the availability under the June 2016 Stock Repurchase Plan by May 2017. Throughout the program, Holdings repurchased 8,392,000 shares at a cumulative cost of approximately $500.0 million and an average price per share of $59.58.

On March 30, 2017, Holdings announced that its Board of Directors approved a new stock repurchase plan that permitted Holdings to repurchase an incremental $500.0 million in shares of Holdings' common stock (the "March 2017 Stock Repurchase Plan"). As of February 15, 2018, Holdings had repurchased 2,775,000 shares at a cumulative cost of approximately $157.2 million and an average price per share of $56.65 under the March 2017 Stock Repurchase Plan, leaving approximately $342.8 million available for permitted repurchases. We did not purchase additional Holdings' common stock under the June 2016 Stock Repurchase Plan during fourth quarter 2017.

Please see the discussion regarding forward-looking statements included under the caption "Cautionary Note Regarding Forward-Looking Statements" and "Item 1A. Risk Factors" for a discussion of some of the uncertainties, risks and assumptions associated with these statements.

The following discussion and analysis presents information that we believe is relevant to an assessment and understanding of our consolidated balance sheets and results of operations. This information should be read in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this Annual Report.

Overview

We are the largest regional theme park operator in the world based on the number of parks we operate. Of our 20 regional theme and waterparks, 17 are located in the United States, two parks are located in Mexico and one is located in Montreal, Canada. Our parks are located in geographically diverse markets across North America and generally offer a broad selection of state-of-the-art and traditional thrill rides, water attractions, themed areas, concerts and shows, restaurants, game venues and retail outlets, thereby providing a complete family-oriented entertainment experience. We work continuously to improve our parks and our guests' experiences and to meet our guests' evolving needs and preferences.

Our revenue is derived from (i) the sale of tickets for entrance to our parks (which accounted for approximately 55% of total revenue during the year ended December 31, 2017, and 54% of total revenues during the years ended December 31, 2016 and 2015), (ii) the sale of food and beverages, merchandise, games and attractions, parking and other services inside our parks, (iii) sponsorship, licensing and other fees, including revenue earned under international development contracts, and (iv) accommodations revenue. Revenues from ticket sales and in-park sales are primarily impacted by park attendance. Revenues from sponsorship, licensing and other fees can be impacted by the term, timing and extent of services and fees under these arrangements, which can result in fluctuations from year to year. During 2017, our earnings from park operations excluding the impact of interest, taxes, depreciation, amortization and any other non-cash income or expenditures ("Park EBITDA") improved primarily as a result of revenue growth, partially offset by an increase in cash operating costs. The increase in revenue was primarily driven by a 1% increase in total guest spending per capita, which excludes sponsorship, licensing, accommodations and other fees, a 1% increase in attendance and an 18% increase in sponsorship and licensing revenue, including growth in revenue earned under international development contracts.

Table of Contents

Our principal costs of operations include salaries and wages, employee benefits, advertising, third party services, repairs and maintenance, utilities and insurance. A large portion of our expenses is relatively fixed as our costs for full-time employees, maintenance, utilities, advertising and insurance do not vary significantly with attendance.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenses earned and incurred during the reporting period. Critical accounting estimates are fundamental to the portrayal of both our financial condition and results of operations and often require difficult, subjective and complex estimates and judgments. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from the continuing changes in the economic environment will be reflected in the financial statements in future periods. The following discussion addresses the items we have identified as our critical accounting estimates. See Note 2 to the consolidated financial statements included elsewhere in this Annual Report for further discussion of these and other accounting policies.

Valuation of Long-Lived Assets

Goodwill and intangible assets with indefinite useful lives are tested for impairment annually, or more frequently if events or circumstances indicate that the assets may be impaired. We identify our reporting unit and determine the carrying value of the reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to the reporting unit. We then determine the fair value of the reporting unit and compare it to the carrying amount of the reporting unit. All of our parks are operated in a similar manner and have comparable characteristics in that they produce and distribute similar services and products using similar processes, have similar types of customers, are subject to similar regulations and exhibit similar economic characteristics. As such, we are a single reporting unit. For each year, the fair value of the single reporting unit exceeded our carrying amount (provided that we have one reporting unit at the same level for which our Holdings' common stock is traded, we believe our market capitalization is the best indicator of our reporting unit's fair value). In September 2012, the FASB amended FASB ASC Topic 350, Intangibles - Goodwill and Other, which permits entities to perform a qualitative analysis on indefinite-lived intangible assets to determine if it is more likely than not that the fair value of the intangible asset was less than its carrying amount as a basis for determining whether it was necessary to perform a quantitative impairment test. We adopted this amendment in September 2012 and have performed a qualitative analysis on our indefinite-lived intangible assets during the fourth quarter of each year.

The fair value of indefinite-lived intangible assets is generally determined based on a discounted cash flow analysis. An impairment loss occurs to the extent that the carrying value exceeds the fair value. For goodwill, if the fair value of the reporting unit were to be less than the carrying amount, an impairment loss would be recognized to the extent that the carrying amount of the reporting unit exceeds its fair value.

We review long-lived assets, including finite-lived intangible assets subject to amortization, for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of an asset or groups of assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or group of assets to the future net cash flows expected to be generated by the asset or group of assets. If such assets are not considered to be fully recoverable, any impairment to be recognized is measured by the amount by which the carrying amount of the asset or group of assets exceeds its respective fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Accounting for Income Taxes

As part of the process of preparing consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves us estimating our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as depreciation periods for our property and equipment and recognition of our deferred revenue, for tax and financial accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. We must then assess the likelihood that our deferred tax assets (primarily net operating loss carryforwards) will be recovered by way of offset against taxable income. To the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a

Table of Contents

valuation allowance or increase or decrease this allowance in a period, we must reflect such amount as income tax expense or benefit in the consolidated statements of operations.

A high degree of management judgment is required in determining our provision or benefit for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. Variables that will impact whether our deferred tax assets will be utilized prior to their expiration include, among other things, attendance, per capita spending and other revenues, capital expenditures, levels of debt, interest rates, operating expenses, sales of assets, and changes in state or federal tax laws. In determining the valuation allowance we do not consider, and under generally accepted accounting principles cannot consider, the possible changes in state or federal tax laws until the laws change. To the extent we reduce capital expenditures, our future accelerated tax deductions for our rides and equipment will be reduced, and our interest expense deductions could correspondingly decrease as cash flows that previously would have been utilized for capital expenditures could be utilized to lower our outstanding debt balances. Increases in capital expenditures without corresponding increases in net revenues would reduce short-term taxable income and increase the likelihood of additional valuation allowances being required as net operating loss carryforwards expire prior to their utilization. Conversely, increases in revenues in excess of operating expenses would reduce the likelihood of additional valuation allowances being required as the short-term taxable income would increase the utilization of net operating loss carryforwards prior to their expiration. See Note 2 and Note 11 to the consolidated financial statements included elsewhere in this Annual Report for further discussion.

Revenue Recognition

We recognize revenue upon admission into our parks, provision of our services or when products are delivered to our guests. Revenues are presented in the accompanying consolidated statements of operations net of sales taxes collected from our guests and remitted or payable to government taxing authorities. In contrast to our season pass and other multi-use offerings (such as our all-season dining pass program, which enables season pass holders and members to eat meals and snacks any day they visit the park for one upfront payment) that expire at the end of each operating season, the membership program continues on a month-to-month basis after the initial twelve-month membership term and can be canceled any time after the initial term pursuant to the terms of the membership program. Guests enrolled in the membership program can visit our parks an unlimited number of times anytime they are open as long as the guest remains enrolled in the membership program. For season passes, memberships in the initial twelve-month term and other multi-use admissions, we estimate a redemption rate based on historical experience and other factors and assumptions we believe to be customary and reasonable and recognize a pro-rata portion of the revenue as the guest attends our parks. We review the estimated redemption rate regularly and on an ongoing basis and revise it as necessary throughout the year. Amounts received for multi-use admissions in excess of redemptions are recognized in deferred revenue. For active memberships after the initial twelve-month term, we recognize revenue monthly as payments are received.

We have entered into multiple agreements to assist third parties in the planning, design, development and operation of Six Flags-branded theme parks outside of North America. Pursuant to these agreements, we provide exclusivity, brand licensing, and other services to assist in the design, development and project management of Six Flags-branded theme parks, as well as initial and ongoing management services. Each significant deliverable qualifies as a separate unit of accounting. We recognize revenue under these agreements over the relevant service period of each unit of accounting based on its relative selling price, as determined by our best estimate of selling price. Our best estimate of selling price is established consistent with our overall pricing strategy and includes, but is not limited to, consideration of current market conditions, various risk factors and our required return and profit objectives. We review the service period of each unit of accounting on an ongoing basis and revise it as necessary throughout the year. Revisions to the relevant service periods of the units of accounting may result in revisions to revenue in future periods and are recognized in the period in which the change is identified.

Recent Events

On February 21, 2017, we announced that we signed definitive agreements with our current partner in China to develop two additional Six Flags-branded parks in China. The theme park and waterpark will be located in Bishan, a district of Chongqing. The agreements do not require us to make any capital investments in the parks. As compensation for our design and management services, we will receive fees over the design and development period as well as ongoing remuneration once the parks open to the public.

On March 30, 2017, we announced that Holdings' Board of Directors approved a stock repurchase plan that allows us to repurchase an incremental $500.0 million of our common stock. The amount of shares of common stock authorized to be repurchased under the plan was in addition to the amount remaining under our existing stock repurchase plan on that date, which has since been fully utilized. We have repurchased just under $2.0 billion of Holdings' common stock at an average price of $39.60 since February 2011 and have approximately $342.8 million available for repurchases under our current plans.

On March 30, 2017, we also announced that we completed an analysis of the costs and benefits of pursuing a spin-off of our real estate assets into a Real Estate Investment Trust ("REIT") and determined that it would not be in the best interest of our stockholders to proceed with such a transaction at that time. The cost of the REIT transaction, the ongoing operational complexity, the limitations on future strategic flexibility and our significant future growth opportunities were the primary factors in making that determination. However, we could revisit the merits of pursuing such a transaction should circumstances change.

On April 13, 2017, we issued an additional $700.0 million of 4.875% Senior Notes due 2024 (the "2024 Notes Add-on") and $500.0 million of 5.50% Senior Notes due 2027 (the "2027 Notes"). A portion of the net proceeds from the issuance of these notes was used to redeem all of the outstanding 2021 Notes (as defined in Note 7 to the consolidated financial statements included elsewhere in this Annual Report) and to satisfy and discharge the indenture governing the 2021 Notes. The remaining net proceeds were used to repurchase shares of our common stock.

On April 22, 2017, we announced the opening of a new 67-acre waterpark in Oaxtepec, Mexico, located about 50 miles southwest of Six Flags Mexico.

On April 27, 2017, we announced that we entered into an agreement with EPR Properties to operate Waterworld California, Northern California's largest waterpark, located 18 miles southeast of Six Flags Discovery Kingdom.

On April 28, 2017, we announced that we entered into an agreement to repurchase approximately five million shares of Holdings' common stock from H Partners and affiliated funds. H Partners acquired its shares in Holdings in 2010 and, prior to the repurchase, was Holdings' largest stockholder.

On July 18, 2017, we announced that Holdings' Board of Directors appointed James Reid-Anderson, who had been serving as Executive Chairman of Holdings since February 2016, as Holdings' Chairman, President and Chief Executive Officer effective July 18, 2017. Mr. Reid-Anderson replaced John M. Duffey, who retired as Chief Executive Officer of Holdings and as a director. Mr. Reid-Anderson formerly served as Chairman, President and Chief Executive Officer of Holdings from August 2010 through February 2016.

On September 20, 2017, we provided an update about our two parks in Mexico following the earthquakes that struck in the State of Puebla, south of Mexico City, which is about 50 miles from our new waterpark in Oaxtepec. Our theme park in Mexico City sustained minimal damage. Our new waterpark sustained damage to a number of structures and did not reopen until December 2017.

On October 26, 2017, we announced the addition of three more parks to be built in China. Six Flags Kids World—the first park of its kind and designed especially for families with young children—will be built adjacent to both Six Flags Zhejiang and Six Flags Chongqing. Additionally, the all-new Six Flags Adventure Park, offering high-energy outdoor thrills, will adjoin the Six Flags Chongqing complex. The agreements for these parks do not require us to make any capital investments in the parks. As compensation for our design and management services, Six Flags will receive fees during the design and development period as well as an ongoing remuneration once the parks open to the public.

On November 8, 2017, we announced that Holdings' Board of Directors declared a fourth quarter cash dividend of $0.70 per share of common stock payable December 11, 2017 to stockholders of record as of November 30, 2017. This dividend represented a 9% increase on an annualized basis. On February 7, 2018, we announced that Holdings' Board of Directors declared a first quarter 2018 cash dividend of $0.78 per share of common stock payable March 5, 2018 to stockholders of record as of February 19, 2018. This increase represents an additional 11% increase on an annualized basis from the $0.70 dividend paid in December 2017.

On February 20, 2018, we announced a new initiative in connection with Jones Lang LaSalle, Inc., a global professional services firm that specializes in real estate and investment management, to power two more of our parks – Six Flags Discovery Kingdom in Vallejo, California and Six Flags Magic Mountain, near Los Angeles, California – almost entirely with solar power. A renewable energy independent power producer will build, own and operate the renewable energy systems in California. Separately, we recently announced that Six Flags Great Adventure in Jackson, New Jersey will soon begin construction of a solar energy project.

While our international momentum remains strong, our partner is currently in arrears on payments due to us. While this is an unfortunate development, we remain in close working contact with our partner. All parties believe that opening a Six Flags park is key to the success of the overall complex in Dubai and that a satisfactory resolution will be achieved.

Year Ended December 31, 2017 vs. Year Ended December 31, 2016

Revenue

Revenue for the year ended December 31, 2017 totaled $1,359.1 million, a 3% increase compared to $1,319.4 million for the year ended December 31, 2016. The increase in revenue was primarily attributable to a 1% increase in attendance driven by strong season pass and membership sales, and by a $0.86, or 2%, increase in total revenue per capita, calculated as total revenue divided by total attendance. Per capita guest spending, which excludes sponsorship, licensing, Six Flags Great Escape Lodge & Indoor Waterpark accommodations and other fees, increased by $0.54, or 1%, to $41.61 during the year ended December 31, 2017 from $41.07 during the year ended December 31, 2016, primarily as a result of ticket price gains, partially offset by lower in-park spending per capita due to a higher mix of season pass holder and member attendance, which lowers per capita guest spending but increases overall guest spending over the course of the operating season.

Admissions revenue per capita increased $0.61, or 3%, during the year ended December 31, 2017 relative to the year ended December 31, 2016. The increase in admissions revenue per capita was primarily driven by modest price increases on all ticket types and membership revenue from active memberships past the initial twelve-month term, during which time members continue to pay their membership fees on a month-to-month basis, partially offset by the higher mix of season pass holder and member attendance. Non-admissions revenue per capita decreased $0.07, or less than 1%, during the year ended December 31, 2017 relative to the year ended December 31, 2016. The decrease in non-admissions per capita guest spending was driven by the higher percentage of season pass holder and member attendance, partially offset by the continued success of our all-season dining pass.

Operating expenses

Operating expenses for the year ended December 31, 2017 increased $19.7 million, or 4%, relative to the year ended December 31, 2016, primarily as a result of increases in statutory and market-based wage rate increases, an increase in seasonal labor resulting from the expansion of our Holiday in the Park^® event at Six Flags New England, increases in rent and utility costs related to the operations of our new waterparks in Oaxtepec, Mexico and Concord, California, as well as an increase in credit card processing fees, operating supplies and other services related to the growth in attendance and revenue.

Selling, general and administrative expenses

Selling, general and administrative expenses for the year ended December 31, 2017 decreased $133.3 million, or 46%, compared to the year ended December 31, 2016, primarily as a result of a net decrease in incentive-based compensation

Table of Contents

expense resulting from the 2017 Performance Award, for which we reduced incentive-based compensation during the year ended December 31, 2017 as late achievement of the 2017 Performance Award is not deemed probable to occur until 2018. This reduction was partially offset by increased costs related to insurance, legal and other professional services.

Cost of products sold

Cost of products sold for the year ended December 31, 2017 increased $0.8 million, or 1%, compared to the year ended December 31, 2016. Cost of products sold as a percentage of non-admission revenue for the years ended December 31, 2017 and 2016 was comparable for both periods.

Depreciation and amortization expense

Depreciation and amortization expense for the year ended December 31, 2017 increased $4.8 million, or 4.5%, compared to the year ended December 31, 2016. The increase in depreciation and amortization expense is primarily due to asset additions made in conjunction with our ongoing capital program.

Loss on disposal of assets

Loss on disposal of assets increased by $2.0 million, or 101%, for the year ended December 31, 2017 relative to the year ended December 31, 2016, primarily as a result of the disposal of more assets during the current period in conjunction with our ongoing capital program relative to the comparable period in the prior year as well as a gain recognized on the sale of underutilized assets in the prior year.

Interest expense, net

Interest expense, net increased $17.1 million, or 21%, for the year ended December 31, 2017 relative to the year ended December 31, 2016 as a result of the incremental interest incurred on a higher debt balance resulting from the issuance of the 2024 Notes Add-on and the 2027 Notes.

Loss on debt extinguishment

On April 13, 2017, Holdings issued $700.0 million of 4.875% senior unsecured notes due 2024, and $500.0 million of 5.50% senior unsecured notes due 2027. We used a portion of the proceeds from the issuance of the notes to redeem all of the outstanding 2021 Notes and to satisfy and discharge the indenture governing the 2021 Notes. In connection with the extinguishment of the 2021 Notes, we recognized a loss on debt extinguishment of $36.9 million for the year ended December 31, 2017.

On June 21, 2017, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points. In conjunction with this amendment, we recognized a loss on debt extinguishment of $0.2 million for the year ended December 31, 2017.

On September 29, 2017, we repaid all amounts outstanding under the Refinance Loan (as defined in Note 7 to the consolidated financial statements included elsewhere in this Annual Report). In connection with the repayment of the Refinance Loan, we recognized a nominal amount as loss on debt extinguishment for the year ended December 31, 2017.

See Note 7 to the consolidated financial statements included elsewhere in this Annual Report for further discussion.

Income tax expense

Income tax expense was $16.0 million for the year ended December 31, 2017 compared to $76.5 million for the year ended December 31, 2016. The decrease in income tax expense is the result of the passage of the Tax Cuts and Jobs Act (H.R. 1) ("the Act") on December 22, 2017. The Act reduced the corporate tax rate from 35% to 21%, resulting in a remeasurement of our deferred tax balances.

See Note 11 to the consolidated financial statements included elsewhere in this Annual Report for further discussion.

Year Ended December 31, 2016 vs. Year Ended December 31, 2015

Revenue

Revenue for the year ended December 31, 2016 totaled $1,319.4 million, a 4% increase compared to $1,263.9 million for the year ended December 31, 2015. The increase in revenue was primarily attributable to a 5% increase in attendance driven by

Table of Contents

strong season pass and membership sales, partially offset by a $0.44, or 1% decrease in total revenue per capita, calculated as total revenue divided by total attendance. Per capita guest spending, which excludes sponsorship, licensing, Six Flags Great Escape Lodge & Indoor Waterpark accommodations and other fees, decreased $0.53, or 1%, to $41.07 during the year ended December 31, 2016 from $41.60 during the year ended December 31, 2015 primarily as a result of a substantially higher mix of season pass holder and member attendance, which lowers per capita guest spending but increases overall guest spending over the course of the operating season, and the continued weakening of the Mexican Peso and the Canadian Dollar. These adverse impacts were partially offset by the continued success of our all-season dining pass, modest price increases on all ticket types and ongoing payments received on active memberships after the initial twelve-month term.

Admissions revenue per capita decreased $0.32, or 1%, during the year ended December 31, 2016 relative to the year ended December 31, 2015. The decrease in admissions revenue per capita was primarily driven by the substantially higher mix of season pass holder and member attendance and the negative impact of the weakened Mexican Peso and Canadian Dollar. These negative impacts were partially offset by modest price increases on all ticket types and membership revenue for active memberships past the initial twelve-month term during which time members continue to pay their membership fees on a month-to-month basis. On a constant currency basis, admissions revenue per capita decreased $0.10 or less than 1%. Non-admissions revenue per capita decreased $0.21, or 1%, during the year ended December 31, 2016 relative to the year ended December 31, 2015. The decrease in non-admissions per capita guest spending was also driven by the higher percentage of season pass holder and member attendance and the weakened Mexican Peso and Canadian Dollar previously discussed and was partially offset by the continued success of our all-season dining pass. On a constant currency basis, non-admissions revenue per capita increased $0.03, or less than 1%.

Operating expenses

Operating expenses for the year ended December 31, 2016 increased $24.2 million, or 5%, relative to the year ended December 31, 2015, primarily as a result of increases in statutory and market-based wage rates, an increase in seasonal labor resulting from the expansion of our Holiday in the Park^® event at Six Flags St. Louis and Six Flags America, as well as an increase in credit card processing fees, operating supplies and other services related to the growth in attendance and revenue. These increases were partially offset by a decrease in utility costs and the continued weakening of the Mexican Peso and Canadian Dollar, which favorably impacted expenses.

Selling, general and administrative expenses

Selling, general and administrative expenses for the year ended December 31, 2016 increased $57.0 million, or 24%, compared to the year ended December 31, 2015, primarily as a result of (i) a net increase in incentive-based compensation expense resulting from the 2017 Performance Award, which we began recognizing during the year ended December 31, 2016 as achievement of this award was deemed probable, and (ii) increased costs related to insurance, legal and other professional services. These increases were partially offset by the continued weakening of the Mexican Peso and Canadian Dollar.

Cost of products sold

Cost of products sold for the year ended December 31, 2016 increased $8.9 million, or 9%, compared to the year ended December 31, 2015. Cost of products sold as a percentage of non-admission revenue for the year ended December 31, 2016 increased slightly relative to the year ended December 31, 2015 primarily as a result of increased food and beverage sales associated with our all-season dining pass program, which results in an increase in food and beverage sales but at slightly lower margin.

Depreciation and amortization expense

Depreciation and amortization expense for the year ended December 31, 2016 decreased $0.5 million, or less than 1%, compared to the year ended December 31, 2015. The reduction in depreciation and amortization expense is primarily due to the impact of the weakened Mexican Peso and Canadian Dollar. On a constant currency basis, depreciation and amortization expense increased $0.5 million primarily as a result of asset additions made in conjunction with our ongoing capital program.

Loss on disposal of assets

Loss on disposal of assets decreased by $7.9 million, or 80%, for the year ended December 31, 2016 relative to the year ended December 31, 2015, as a result of the sale of excess land at Six Flags St. Louis in 2015.

Table of Contents

Interest expense, net

Interest expense, net increased $6.0 million, or 8%, for the year ended December 31, 2016 relative to the year ended December 31, 2015 as a result of the incremental interest incurred on a higher debt balance resulting from the increased borrowings under the Amended and Restated Revolving Loan and the issuance of the 2024 Notes in June 2016.

Loss on debt extinguishment

On June 16, 2016, Holdings issued $300.0 million of 4.875% senior unsecured notes. We used $150.0 million of the proceeds from the issuance of the notes to reduce our borrowings under the Amended and Restated Term Loan and we recognized a loss on debt extinguishment of $2.4 million for the year ended December 31, 2016.

On December 20, 2016, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points. In conjunction with this amendment, we recognized a loss on debt extinguishment of $0.5 million for the year ended December 31, 2016.

See Note 7 to the consolidated financial statements included elsewhere in this Annual Report for further discussion.

Income tax expense

Income tax expense was $76.5 million for the year ended December 31, 2016 compared to $70.4 million for the year ended December 31, 2015. The increase in income tax expense is the result of an increase in our effective tax rate primarily due to a discrete federal tax benefit recognized in the prior year resulting from a change in accounting method for federal income tax purposes related to recoverable bankruptcy costs as well as the release of state valuation allowances in several jurisdictions related to state tax law changes in the prior year.

Liquidity, Capital Commitments and Resources

General

Our principal sources of liquidity are cash generated from operations, funds from borrowings and existing cash on hand. Our principal uses of cash include the funding of working capital obligations, debt service, investments in parks (including capital projects), common stock dividends, payments to our partners in the Partnership Parks and common stock repurchases.

During the years ended December 31, 2017, 2016 and 2015, Holdings paid $227.1 million, $220.3 million and $201.0 million, respectively, in cash dividends on its common stock. One of our fundamental business goals is to generate superior returns for our stockholders over the long term. As part of our strategy to achieve this goal, we have declared and paid quarterly cash dividends each quarter beginning with the fourth quarter of 2010. Holdings' Board of Directors has since increased the quarterly cash dividend multiple times and in November 2017, Holdings' Board of Directors declared another increase in our ongoing quarterly cash dividend from $0.64 per share of common stock to $0.70 per share of common stock. Additionally, in February 2018, Holdings' Board of Directors increased the quarterly cash dividend from $0.70 per share of common stock to $0.78 per share of common stock. The amount and timing of any future dividends payable on Holdings' common stock are within the sole discretion of Holdings' Board of Directors. Based on (i) our current number of shares outstanding and (ii) estimates of share repurchases, restricted stock vesting and option exercises, we currently anticipate paying approximately $265 million in total cash dividends on our common stock during the 2018 calendar year.

In November 2013, Holdings' Board of Directors approved a stock repurchase program that permitted Holdings to repurchase up to $500.0 million in shares of Holdings' common stock over a four-year period (the "November 2013 Stock Repurchase Plan"). Holdings fully utilized the availability under the November 2013 Stock Repurchase Plan in August 2016. Throughout the program, Holdings repurchased 11,428,000 shares at a cumulative cost of approximately $500.0 million and an average price per share of $43.75.

On June 7, 2016, Holdings announced that its Board of Directors approved a new stock repurchase program that permitted Holdings to repurchase an incremental $500.0 million in shares of Holdings' common stock (the "June 2016 Stock Repurchase Plan"). Holdings fully utilized the availability under the June 2016 Stock Repurchase Plan by May 2017. Throughout the program, Holdings repurchased 8,392,000 shares at a cumulative cost of approximately $500.0 million and an average price per share of $59.58.

On March 30, 2017, Holdings announced that its Board of Directors approved a new stock repurchase plan that permits Holdings to repurchase an incremental $500.0 million in shares of Holdings' common stock (the "March 2017 Stock Repurchase Plan"). As of February 15, 2018, Holdings had repurchased 2,775,000 shares at a cumulative cost of

Table of Contents

approximately $157.2 million and an average price per share of $56.65 under the March 2017 Stock Repurchase Plan, leaving approximately $342.8 million available for permitted repurchases.

The repurchase of common stock and the payment of cash dividends is reflected as a reduction of stockholders' equity.

On June 30, 2015, we entered into the Amended and Restated Credit Facility, which is comprised of the $250.0 million Amended and Restated Revolving Loan and the $700.0 million Amended and Restated Term Loan B. In connection with entering into the Amended and Restated Credit Facility, we repaid the outstanding Term Loan B. The remaining proceeds from the Amended and Restated Credit Facility were primarily used for share repurchases.

On June 16, 2016, Holdings issued $300.0 million of 4.875% senior unsecured notes due July 31, 2024. We used $150.0 million of the proceeds from the issuance of the 2024 Notes to reduce our borrowings under the Amended and Restated Term Loan B. The remaining net proceeds were used for general corporate and working capital purposes, which primarily included repurchases of our common stock.

Also on June 16, 2016, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points through a reduction in the applicable margin from LIBOR plus 2.75% to LIBOR plus 2.50%. In addition to the rate reduction, the $150.0 million prepayment made with proceeds from the 2024 Notes discussed above eliminated all future quarterly amortization payments on the Amended and Restated Term Loan B until maturity in 2022.

On December 20, 2016, we entered into an amendment to the Amended and Restated Credit Facility that further reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points through a reduction in the applicable margin from LIBOR plus 2.50% to LIBOR plus 2.25%, with the elimination of the minimum LIBOR rate requirement.

On April 13, 2017, we issued the 2024 Notes Add-on and the 2027 Notes. A portion of the net proceeds from the issuance of these notes was used to redeem all of the outstanding 2021 Notes and to satisfy and discharge the indenture governing the 2021 Notes, including to pay accrued and unpaid interest to the redemption date and the related redemption premium on the 2021 Notes, and to pay related fees and expenses.

Based on historical and anticipated operating results, we believe that cash flows from operations, available cash and amounts available under the Amended and Restated Credit Facility will be adequate to meet our liquidity needs, including any anticipated requirements for working capital, capital expenditures, common stock dividends, scheduled debt service, obligations under arrangements relating to the Partnership Parks and discretionary common stock repurchases. Additionally, we expect to be able to use our current federal net operating loss carryforwards to reduce our federal income tax liability until 2024. For the years 2018 through 2024, we have significant federal net operating loss carryforwards subject to an annual limitation that we expect will offset approximately $32.5 million of taxable income per year. We do, however, anticipate paying a low level of federal income taxes beginning in the next year or two and estimate a slow growth in federal income taxes payable in cash going forward.

Our current and future liquidity is greatly dependent upon our operating results, which are driven largely by overall economic conditions as well as the price and perceived quality of the entertainment experience at our parks. Our liquidity could also be adversely affected by a disruption in the availability of credit as well as unfavorable weather; natural disasters; contagious diseases, such as Ebola, Zika, or swine or avian flu; accidents or the occurrence of an event or condition at our parks, including terrorist acts or threats inside or outside of our parks; negative publicity; or significant local competitive events, which could significantly reduce paid attendance and revenue related to that attendance at any of our parks. While we work with local police authorities on security-related precautions to prevent certain types of disturbances, we can make no assurance that these precautions will be able to prevent these types of occurrences. However, we believe that our ownership of many parks in different geographic locations reduces the effects of adverse weather and these other types of occurrences on our consolidated results. If such an adverse event were to occur, we may be unable to borrow under the Amended and Restated Revolving Loan or may be required to repay amounts outstanding under the Amended and Restated Credit Facility and/or may need to seek additional financing. In addition, we expect that we may be required to refinance all or a significant portion of our existing debt on or prior to maturity, requiring us to potentially seek additional financing. The degree to which we are leveraged could adversely affect our ability to obtain any additional financing. See "Cautionary Note Regarding Forward-Looking Statements" and "Item 1A. Risk Factors" included elsewhere in this Annual Report.

Table of Contents

As of December 31, 2017, our total indebtedness, net of discount and deferred financing costs, was $2,021.2 million, which included $986.5 million of the 2024 Notes, $497.6 million of the 2027 Notes, and $537.1 million outstanding under the Amended and Restated Credit Facility. Based on (i) non-revolving credit debt outstanding on that date, (ii) anticipated levels of working capital revolving borrowings during 2018 and 2019, (iii) estimated interest rates for floating-rate debt and (iv) the 2024 Notes and the 2027 Notes, we anticipate annual cash interest payments of approximately $100 million during 2018 and 2019. Under the Amended and Restated Credit Facility, all remaining outstanding principal of the Amended and Restated Term Loan B is due and payable on June 30, 2022.

As of December 31, 2017, we had approximately $77.5 million of unrestricted cash and $231.3 million available for borrowing under the Amended and Restated Revolving Loan. Our ability to borrow under the Amended and Restated Revolving Loan is dependent upon compliance with certain conditions, including a maximum senior leverage maintenance covenant, a minimum interest coverage covenant and the absence of any material adverse change in our business or financial condition. If we were to become unable to borrow under the Amended and Restated Revolving Loan, and we failed to meet our projected results from operations significantly, we might be unable to pay in full our off-season obligations. A default under the Amended and Restated Revolving Loan could permit the lenders under the Amended and Restated Credit Facility to accelerate the obligations thereunder. The Amended and Restated Revolving Loan expires on June 30, 2020. The terms and availability of the Amended and Restated Credit Facility and other indebtedness are not affected by changes in the ratings issued by rating agencies in respect of our indebtedness. For a more detailed description of our indebtedness, see Note 7 to the consolidated financial statements included elsewhere in this Annual Report.

We currently plan on spending approximately 9% of annual revenues on capital expenditures during the 2018 calendar year.

During the year ended December 31, 2017, net cash provided by operating activities was $445.1 million. Net cash used in investing activities during the year ended December 31, 2017 was $130.2 million, consisting primarily of capital expenditures, partially offset by proceeds received from the disposal of assets. Net cash used in financing activities during the year ended December 31, 2017 was $376.9 million, primarily attributable to the payment of cash dividends, stock repurchases, distributions to our noncontrolling interests and the payment of debt issuance costs in connection with the issuance of the 2024 Notes Add-on and 2027 Notes. These uses of cash were partially offset by the proceeds from the 2024 Notes Add-on and 2027 Notes, a portion of which was used to retire our 2021 Notes, and proceeds from the exercise of stock options.

Since our business is both seasonal in nature and involves significant levels of cash transactions, our net operating cash flows are largely driven by attendance and per capita spending levels because most of our cash-based expenses are relatively fixed and do not vary significantly with either attendance or per capita spending. These cash-based operating expenses include salaries and wages, employee benefits, advertising, third party services, repairs and maintenance, utilities and insurance.

Partnership Park Obligations

We guarantee certain obligations relating to the Partnership Parks. These obligations include (i) minimum annual distributions (including rent) of approximately $71.1 million in 2018 (subject to cost of living adjustments in subsequent years) to the limited partners in the Partnerships Parks (based on our ownership of units as of December 31, 2017, our share of the distribution will be approximately $31.1 million), (ii) minimum capital expenditures at each of the Partnership Parks during rolling five-year periods, based generally on 6% of the Partnership Park's revenues, (iii) an annual offer to purchase all outstanding limited partnership units at the Specified Price to the extent tendered by the unit holders, which annual offer must remain open from March 31 through late April of each year, and any limited partnership interest tendered during such time period must be fully paid for no later than May 15th of that year, (iv) making annual ground lease payments, and (v) either (a) purchasing all of the outstanding limited partnership interests in the Partnership Parks through the exercise of a call option upon the earlier of the occurrence of certain specified events and the end of the term of the partnerships that hold the Partnership Parks in 2027 (in the case of Georgia) and 2028 (in the case of Texas), or (b) causing each of the partnerships that hold the Partnership Parks to have no indebtedness and to meet certain other financial tests as of the end of the term of such partnership. See Note 15 to the consolidated financial statements included elsewhere in this Annual Report for additional information.

After payment of the minimum distribution, we are entitled to a management fee equal to 3% of prior year gross revenues and, thereafter, any additional cash will be distributed first to management fee in arrears, repayment of any interest and principal on intercompany loans with any additional cash being distributed 95% to us, in the case of SFOG, and 92.5% to us, in the case of SFOT.

(4)

Represents obligations as of December 31, 2017 with respect to insurance, inventory, media and advertising commitments, computer systems and hardware, estimated annual license fees to Warner Bros. (through 2022) and new rides and attractions. Of the amount shown for 2018, approximately $83.6 million represents capital items. The amounts in respect of new rides and attractions were computed as of December 31, 2017 and include estimates by us of costs needed to complete such improvements that, in certain cases, were not legally committed at that date. Amounts shown do not include obligations to employees that cannot be quantified as of December 31, 2017, which are discussed below. Amounts shown also do not include purchase obligations existing at the individual park-level for supplies and other miscellaneous items, none of which are individually material.

Other Obligations

During each of the years ended December 31, 2017, 2016 and 2015, we made contributions to our defined benefit pension plan of $6.0 million. To control increases in costs, our pension plan was "frozen" effective March 31, 2006, pursuant to which most participants (excluding certain union employees whose benefits have subsequently been frozen) no longer continued to earn future pension benefits. Effective February 16, 2009, the remaining participants in the pension plan no longer earned future benefits. See Note 13 to the consolidated financial statements included elsewhere in this Annual Report for more information on our pension benefit plan.

We expect to make contributions of approximately $6.0 million in 2018 to our pension plan based on the 2017 actuarial valuation. We plan to make a contribution to our 401(k) plan in 2018, and our estimated expense for employee health insurance for 2018 is $17.7 million.

The vast majority of our capital expenditures in 2018 and beyond will be made on a discretionary basis. We plan on spending approximately 9% of annual revenues on capital expenditures during the 2018 calendar year.

We maintain insurance of the type and in amounts that we believe is commercially reasonable and that is available to businesses in our industry. See "Insurance" under "Item 1. Business." Our insurance premiums and self-insurance retention levels have remained relatively constant during the three-year period ending December 31, 2017. We cannot predict the level of the premiums that we may be required to pay for subsequent insurance coverage, the level of any self-insurance retention applicable thereto, the level of aggregate coverage available or the availability of coverage for specific risks.

We are party to various legal actions arising in the normal course of business. See "Legal Proceedings" and Note 15 to the consolidated financial statements included elsewhere in this Annual Report for information on certain significant litigation.

We may from time to time seek to retire our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on the prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Market Risks and Sensitivity Analyses

Like other companies, we are exposed to market risks relating to fluctuations in interest rates and currency exchange rates. The objective of our financial risk management is to minimize the negative impact of interest rate and foreign currency

Table of Contents

exchange rate fluctuations on our operations, cash flows and equity. We do not acquire market risk sensitive instruments for trading purposes.

In April 2014, we entered into three separate interest rate swap agreements (collectively, the "Interest Rate Swap Agreements") that we designated and documented as cash flow hedges. We entered into the Interest Rate Swap Agreements with a notional amount of $200.0 million to mitigate the risk of an increase in the LIBOR interest rate above the 0.75% minimum LIBOR rate in effect on the Term Loan B. The Interest Rate Swap Agreements expired in December 2017.

On March 31, 2017, the Interest Rate Swap Agreements were de-designated due to a change in the forecasted borrowings. The Interest Rate Swap Agreements continued to serve as economic hedges and provided protection against rising interest rates for the Amended and Restated Term Loan B (as defined in Note 7 to the consolidated financial statements included elsewhere in this Annual Report) during the year ended December 31, 2017. Subsequent to the de-designation, the amounts recorded in accumulated other comprehensive loss have been amortized into earnings through the original December 2017 maturity date. As of the year ended December 31, 2017, the Interest Rate Swap Agreements have expired and all related amounts previously held as derivative assets and liabilities on our consolidated balance sheets and previously recorded in accumulated other comprehensive income ("AOCI") have been realized in earnings. See Note 6 to the consolidated financial statements included elsewhere in this Annual Report for further discussion.

The following is an analysis of the sensitivity of the market value, operations and cash flows of our market-risk financial instruments to hypothetical changes in interest rates as if these changes occurred as of December 31, 2017. The range of potential change in the market chosen for this analysis reflects our view of changes that are reasonably possible over a one-year period. Market values are the present values of projected future cash flows based on the interest rate assumptions. These forward-looking disclosures are selective in nature and only address the potential impacts from financial instruments. They do not include other potential effects which could impact our business as a result of these changes in interest and foreign currency exchange rates.

As of December 31, 2017, we had total debt of $2,021.2 million, of which $1,484.1 million represents fixed-rate debt. The remaining $537.1 million balance represents floating-rate debt. For fixed-rate debt, interest rate changes affect the fair market value but do not impact book value, operations or cash flows. Conversely, for floating-rate debt, interest rate changes generally do not affect the fair market value but do impact future operations and cash flows, assuming other factors remain constant.

Assuming other variables remain constant (such as foreign exchange rates and debt levels), the pre-tax operating and cash flow impact resulting from a one percentage point increase in interest rates would be approximately $5.4 million. See Note 7 to the consolidated financial statements included elsewhere in this Annual Report for information on interest rates under our debt agreements.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). The amendments in ASU 2014-09 provide for a single, principles-based model for revenue recognition that replaces the existing revenue recognition guidance. In August 2015, the FASB issued Accounting Standards Updated 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date, to defer the effective date of ASU 2014-09 for one year. Therefore, the new guidance will be effective for annual and interim periods beginning after December 15, 2017 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. In March and April 2016, the FASB issued Accounting Standards Update No. 2016-08 and No. 2016-10, Revenue from Contracts with Customers (Topic 606) and Principal versus Agent Considerations and Identifying Performance Obligations and Licensing, respectively (together, “ASU 2016-08/10”). The amendments in ASU 2016-08/10 state that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The effective date and transition requirements for the amendments in ASU 2016-08/10 are the same as the effective date and transition requirements in ASU 2015-14. It permits the use of either a retrospective or cumulative effect transition method and early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We have undertaken a review of the Company’s key revenue drivers as it relates to ASU 2014-9. The Company has adopted these standards as of January 1, 2018 and has selected a modified retrospective transition method for the adoption. Based on our evaluation of our revenue streams, the Company has determined that there will not be a material impact as of the date of adoption between the new revenue standard and how we previously recognized revenue, and will not have a material effect on our consolidated balance sheets, results of operations, and cash flows. The Company has finalized what additional information will be disclosed and determined the overall level of disclosure related to revenue recognition will increase.

Table of Contents

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). The main amendments in ASU 2016-02 require recognition on the balance sheet of lease assets and lease liabilities by lessees for those leases classified as operating leases. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. An entity should apply ASU 2016-02 using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and early adoption is permitted; however, the FASB recently proposed an optional transition method for which entities would still adopt ASU 2016-02 using a modified retrospective transition method, but would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. We note that with the adoption of the amendments in ASU 2016-02, operating leases related to certain of our land leases with durations greater than twelve months will require recognition in our consolidated balance sheet under ASU 2016-02. This could have a material effect on our consolidated balance sheets, but we do not anticipate this will have a material effect on our results of operations or cash flows.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"). The amendments in ASU 2016-15 address eight classification issues related to the statement of cash flows:


•	debt prepayment or debt extinguishment costs;


•	settlement of zero-coupon bonds;


•	contingent consideration payments made after a business combination;


•	proceeds from the settlement of insurance claims;


•	proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies;


•	distributions received from equity method investees;


•	beneficial interests in securitization transactions; and


•	separately identifiable cash flows and application of the predominance principle.

ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. An entity should apply ASU 2016-15 using a retrospective transition method to each period presented. We do not anticipate that the adoption of this pronouncement will result in a material impact to the presentation of our statement of cash flows.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). The amendments in ASU 2016-18 require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. An entity should apply ASU 2016-18 using a retrospective transition method to each period presented. We do not anticipate that the adoption of this pronouncement will result in a material impact to the presentation of our statement of cash flows.

In March 2017, the FASB issued Accounting Standards Update No. 2017-07, Compensation-Retirement Benefits (Topic 715): “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” ("ASU 2017-07"). The amendments in ASU 2017-07 require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The amendments in ASU 2017-07 also require that an employer disaggregate the service cost component from the other components of net benefit cost. ASU 2017-07 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements, interim or annual, have not been issued or made available for issuance. That is, early adoption should be within the first interim period if an employer issues interim financial statements. The amendments in ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. We do not anticipate that the adoption of this pronouncement will result in a material impact to the presentation of our net periodic pension cost and net periodic postretirement benefit cost.

comprehensive income (AOCI) to retained earnings "stranded" tax effects resulting from passage of the Act. An entity that elects to reclassify these amounts must reclassify stranded tax effects related to the change in federal tax rate for all items accounted for in other comprehensive income (e.g., employee benefits, cumulative translation adjustments). Entities may also elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal rate (e.g., state taxes). However, because the amendments only relate to the reclassification of the income tax effects of the Act, the underlying guidance requiring the effect of a change in tax laws or rates be included in income from operations is not affected. Upon adoption of ASU 2018-02, entities will be required to disclose their policy for releasing the income tax effects from AOCI. Entities that elect to reclassify the income tax effects of the Act from AOCI to retained earnings must disclose that such an election was made, including a description of reclassified tax effects. ASU 2018-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period for which financial statements, interim or annual, have not been issued or made available for issuance. The amendments in 2018-02 may be applied retrospectively to each period in which the effect of the Act is recognized or an entity may elect to apply the amendments in the period of adoption. The Company anticipates early adoption of these standards in first quarter of 2018, and has not selected an adoption method. We are still evaluating the effects of adopting ASU 2018-02, and this could have a material impact resulting from a reclassification from AOCI to retained earnings on our consolidated balance sheets, comprehensive income, and equity. However, we do not anticipate an impact to our consolidated statement of operations and cash flows.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2017.

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by KPMG LLP, the independent registered public accounting firm that audited our financial statements included herein, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Six Flags Entertainment Corporation:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Six Flags Entertainment Corporation and subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of operations, comprehensive income, equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2017,and the related notes (collectively, the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinion

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements


1.	Description of Business

We own and operate regional theme and waterparks and are the largest regional theme park operator in the world. Of the 20 parks we currently own or operate, 17 parks are located in the United States, two parks are located in Mexico and one park is located in Montreal, Canada.

On April 1, 1998, we acquired the former Six Flags Entertainment Corporation ("Former SFEC", a corporation that has been merged out of existence and that has always been a separate corporation from the current Six Flags Entertainment Corporation ("Holdings")), which had operated regional theme parks under the Six Flags name for nearly 40 years, and established an internationally recognized brand name. We own the "Six Flags" brand name in the United States and foreign countries throughout the world. To capitalize on this name recognition, 17 of our current parks are branded as "Six Flags" parks and beginning in 2014 we also began the development, with third-party partners, of Six Flags-branded theme parks outside of North America.


2.	Summary of Significant Accounting Policies


a.	Basis of Presentation

The consolidated financial statements include our accounts and the accounts of our wholly owned subsidiaries. We also consolidate the partnerships that own Six Flags Over Texas ("SFOT") and Six Flags Over Georgia (including Six Flags White Water Atlanta) ("SFOG", and together with SFOT, the "Partnership Parks") as subsidiaries in our consolidated financial statements as we have determined that we have the power to direct the activities of those entities that most significantly impact the entities' economic performance and we have the obligation to absorb losses and receive benefits from the entities that can be potentially significant to these entities. The equity interests owned by non-affiliated parties in the Partnership Parks are reflected in the accompanying consolidated balance sheets as redeemable noncontrolling interests. The portion of earnings or loss attributable to non-affiliated parties in the Partnership Parks is reflected as net income attributable to noncontrolling interests in the accompanying consolidated statements of operations. See Note 5 for further discussion.

Intercompany transactions and balances have been eliminated in consolidation.


b.	Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.


c.	Fair Value Measurement

Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurement, defines fair value as the exchange prices that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The guidance also specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. In accordance with FASB ASC Topic 820, Fair Value Measurement, these two types of inputs have created the following fair value hierarchy:


•	Level 1: quoted prices in active markets for identical assets;


•	Level 2: inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the instrument; and


•	Level 3: inputs to the valuation methodology are unobservable for the asset or liability.

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

This hierarchy requires the use of observable market data when available. See Note 10 for disclosure of methods and assumptions used to estimate the fair value of financial instruments by classification.


d.	Cash Equivalents

Cash equivalents consists of short-term highly liquid investments with a remaining maturity as of the date of purchase of three months or less, which are readily convertible into cash. For purposes of the consolidated statements of cash flows, we consider all highly liquid debt instruments with remaining maturities as of their date of purchase of three months or less to be cash equivalents. Cash equivalents were not significant as of December 31, 2017 and 2016.


e.	Inventories

Inventories are stated at lower of weighted average cost or net realizable value and primarily consist of products purchased for resale, including merchandise, food and miscellaneous supplies. Products are removed from inventory at weighted average cost. We have recorded a valuation allowance for slow moving inventory of $0.3 million as of December 31, 2017 and 2016.


f.	Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets include $21.1 million and $21.4 million of spare parts inventory for existing rides and attractions as of December 31, 2017 and 2016, respectively. These items are expensed as the repair or maintenance of rides and attractions occur.


g.	Advertising Costs

Production costs of commercials and programming are charged to operations in the year first aired. The costs of other advertising, promotion, and marketing programs are charged to operations when incurred with the exception of direct-response advertising which is charged to the period it will benefit. As of December 31, 2017 and 2016, we had $1.9 million and $1.8 million in prepaid advertising, respectively. The amounts capitalized are included in prepaid expenses.

Advertising and promotions expense was $63.7 million for the year ended December 31, 2017, and $62.8 million for the years ended December 31, 2016, and 2015.


h.	Debt Issuance Costs

We capitalize costs related to the issuance of debt. Debt issuance costs directly related to our Revolving Loan are presented within other assets as debt issuance costs in our consolidated balance sheets. Debt issuance costs directly related to our Amended and Restated Term Loam B and our senior unsecured notes are presented within noncurrent liabilities as a reduction of long-term debt in our consolidated balance sheets. The amortization of such costs is recognized as interest expense using the interest method over the term of the respective debt issue. Amortization related to deferred debt issuance costs was $4.1 million for the year ended December 31, 2017 and $4.5 million for the years ended December 31, 2016 and 2015. See Note 7 for further discussion.


i.	Property and Equipment

Property and equipment additions are recorded at cost and the carrying value is depreciated using the straight-line method over the estimated useful lives of the assets. Maintenance and repair costs that do not improve service potential or extend economic life are charged directly to expense as incurred, while betterments and renewals are generally capitalized as property and equipment. When an item is retired or otherwise disposed of, the cost and applicable accumulated depreciation are removed and the resulting gain or loss is recognized. See Note 3 for further detail of the components of our property and equipment.

The estimated useful lives of the assets are as follows:



Rides and attractions	5 - 25 years
Land improvements	10 - 15 years
Buildings and improvements	Approximately 30 years
Furniture and equipment	5 - 10 years

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements


j.	Goodwill and Indefinite-Lived Intangible Assets

Goodwill and intangible assets with indefinite useful lives are tested for impairment annually, or more frequently if events or circumstances indicate that the assets might be impaired. We identify our reporting unit and determine the carrying value of the reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets, to the reporting unit. We then determine the fair value of the reporting unit and compare it to the carrying amount of the reporting unit. All of our parks are operated in a similar manner and have comparable characteristics in that they produce and distribute similar services and products using similar processes, have similar types of customers, are subject to similar regulations and exhibit similar economic characteristics. As such, we are a single reporting unit. For each year, the fair value of the single reporting unit exceeded our carrying amount (provided that we have one reporting unit at the same level for which our Holdings common stock is traded, we believe our market capitalization is the best indicator of our reporting unit's fair value). In September 2012, the FASB amended FASB ASC Topic 350, Intangibles - Goodwill and Other, which permits entities to perform a qualitative analysis on indefinite-lived intangible assets to determine if it is more likely than not that the fair value of the intangible asset was less than its carrying amount as a basis for determining whether it was necessary to perform a quantitative impairment test. We adopted this amendment in September 2012 and have performed a qualitative analysis on our indefinite-lived intangible assets during the fourth quarter of each year.


k.	Valuation of Long-Lived Assets

We review long-lived assets, including finite-lived intangible assets subject to amortization, for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the asset or group of assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or group of assets to the future net cash flows expected to be generated by the asset or group of assets. If such assets are not considered to be fully recoverable, any impairment to be recognized is measured by the amount by which the carrying amount of the asset or group of assets exceeds its respective fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.


l.	Revenue Recognition

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

pricing strategy and includes, but is not limited to, consideration of current market conditions, various risk factors and our required return and profit objectives. We review the service period of each unit of accounting on an ongoing basis and revise it as necessary throughout the year. Revisions to the relevant service periods of the units of accounting may result in revisions to revenue in future periods and are recognized in the period in which the change is identified.


m.	Accounts Receivable, Net

Accounts receivable are reported at net realizable value and consist primarily of amounts due from guests for the sale of group outings and multi-use admission products, including season passes and the membership program. We are not exposed to a significant concentration of credit risk, however, based on the age of the receivables, our historical experience and other factors and assumptions we believe to be customary and reasonable, we do record an allowance for doubtful accounts. As of December 31, 2017 and 2016, we have recorded an allowance for doubtful accounts of $4.2 million and $3.0 million, respectively. The allowance for doubtful accounts is primarily comprised of estimated defaults under our membership plans.


n.	Derivative Instruments and Hedging Activities

We account for derivatives and hedging activities in accordance with FASB ASC Topic 815, Derivatives and Hedging. This accounting guidance establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities in the consolidated balance sheet and measure those instruments at fair value. If certain conditions are met, a derivative may be specifically designated as a hedge for accounting purposes. The accounting for changes in the fair value of a derivative (e.g., gains and losses) depends on the intended use of the derivative and the resulting designation.

We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and our strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to forecasted transactions. We also assess, both at the hedge's inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items.

Changes in the fair value of a derivative that is effective and that is designated and qualifies as a cash-flow hedge are recorded in other comprehensive income (loss) until operations are affected by the variability in cash flows of the designated hedged item, at which point they are reclassified to interest expense. Changes in fair value of a derivative that is not designated as a hedge are recorded in other income (expense), net in the consolidated statements of operations on a current basis. See Note 6 for further discussion.


o.	Commitments and Contingencies

We are involved in various lawsuits and claims that arise in the normal course of business. Amounts associated with lawsuits or claims are reserved for matters in which it is believed that losses are probable and can be reasonably estimated. In addition to matters in which it is believed that losses are probable, disclosure is also provided for matters in which the likelihood of an unfavorable outcome is at least reasonably possible but for which a reasonable estimate of loss or range of loss is not possible. Legal fees are expensed as incurred. See Note 15 for further discussion.


p.	Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, including net operating loss and other tax carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. We have a valuation allowance of $113.5 million and $92.3 million as of December 31, 2017 and 2016, respectively, due to uncertainties related to our ability to utilize some of our deferred tax assets, primarily consisting of certain state net operating loss and other tax carryforwards, before they expire. The valuation allowance was based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets were recoverable. For the foreseeable future, we project taxable income that will allow for the utilization of all of our federal net operating loss carryforwards before they expire.

Our liability for income taxes is finalized as auditable tax years pass their respective statutes of limitations in the various jurisdictions in which we are subject to tax. However, these jurisdictions may audit prior years for which the statute of limitations is closed for the purpose of making an adjustment to our taxable income in a year for which the statute of limitations

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

has not closed. Accordingly, taxing authorities of these jurisdictions may audit prior years of the group and its predecessors for the purpose of adjusting net operating loss carryforwards to years for which the statute of limitations has not closed.

We classify interest and penalties attributable to income taxes as part of income tax expense. As of December 31, 2017 and 2016, we had no accrued interest and penalties liability.

Because we do not permanently reinvest foreign earnings, United States deferred income taxes have been provided on unremitted foreign earnings to the extent that such foreign earnings are expected to be taxable upon repatriation.

On December 22, 2017, the Tax Cuts and Jobs Act (H.R. 1) ("the Act") was signed into law by President Donald Trump. The Act contains significant changes to corporate taxation, including reduction of the corporate tax rate from 35% to 21% effective January 1, 2018, limitation of the tax deduction for interest expense, limitation of the deduction for net operating losses and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), new taxes concerning global intangible low-tax income (GILTI), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits including the limitation on deductions for certain executive compensation arrangements under Section 162(m) of the Internal Revenue Code. All corporation taxation aspects of the Act are included in our year ended December 31, 2017 tax provision. See footnote 11 for further discussion.


q.	Earnings Per Common Share

Basic earnings per common share is computed by dividing net income attributable to Holdings' common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed by dividing net income attributable to Holdings' common stockholders by the weighted average number of common shares outstanding during the period including the effect of all dilutive common stock equivalents using the treasury stock method. In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.


r.	Stock-Based Compensation

Pursuant to the Six Flags Entertainment Corporation Long-Term Incentive Plan (the "Long-Term Incentive Plan"), Holdings may grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, deferred stock units, performance and cash-settled awards and dividend equivalents to select employees, officers, directors and consultants of Holdings and its affiliates. We recognize the fair value of each grant as compensation expense on a straight-line basis over the vesting period using the graded vesting terms of the respective grant. The fair value of stock option grants is estimated on the date of grant using the Black-Scholes option pricing valuation model. The fair value of stock, restricted stock units and restricted stock awards is the quoted market price of Holdings' stock on the date of grant. See Note 9 for further discussion of stock-based compensation and related disclosures.


s.	Comprehensive Income

Comprehensive income consists of net income, changes in the foreign currency translation adjustment, changes in the fair value of derivatives that are designated as hedges and changes in the net actuarial gains (losses) and amortization of prior service costs on our defined benefit retirement plan.


t.	Redeemable Noncontrolling Interest

We record the carrying amount of our redeemable noncontrolling interests at their fair value at the date of issuance. We recognize the changes in their redemption value immediately as they occur and adjust the carrying value of these redeemable noncontrolling interests to equal the redemption value at the end of each reporting period, if greater than the redeemable noncontrolling interest carrying value.

This method would view the end of the reporting period as if it were also the redemption date for the redeemable noncontrolling interests. We conduct an annual review to determine if the fair value of the redeemable units is less than the redemption amount. If the fair value of the redeemable units is less than the redemption amount, there would be a charge to earnings per share allocable to common stockholders. The redemption amount at the end of each reporting period did not exceed the fair value of the redeemable units.

Notes to Consolidated Financial Statements

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”) to simplify the accounting for employee share-based payments. Upon the adoption of ASU 2016-09, all excess tax benefits and tax deficiencies are to be recognized within income tax expense when the awards vest or are settled. We adopted the new guidance in ASU 2016-09 on January 1, 2017. As a result, we recognized $13.8 million in excess tax benefits related to employee share-based payments during the year ended December 31, 2017. Additionally, we recorded a cumulative effect adjustment to opening retained earnings of $98.7 million to recognize U.S. net operating loss carryforwards attributable to income tax deductions taken in prior periods related to employee share-based payments that were in excess of amounts recognized in our financial statements. Prior to the adoption of ASU 2016-09, we used the "with and without" method when determining when excess tax benefits had been realized, and as a result of our utilization of U.S. net operating loss carryforwards, any excess tax benefits generated to date have not reduced any taxes that would have otherwise been required to be paid. As such, no excess tax benefits had been previously recognized in our financial statements.

In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04"), which eliminates the requirements to calculate the implied fair value of goodwill to measure goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This standard is effective for annual periods beginning after December 15, 2019 and should be applied on a prospective basis. Early adoption is permitted for any goodwill impairment tests performed in the first quarter of 2017 or later. We elected to adopt this accounting standards update in the fourth quarter of 2017. The adoption did not have an impact on our consolidated balance sheets, results of operations, cash flows or financial disclosures; however, this standard did change our policy for our annual goodwill impairment assessment by eliminating the requirement to calculate the implied fair value of goodwill.

In May 2017, the FASB issued Accounting Standards Update No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting ("ASU 2017-09"). The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718. Entities will be required to apply modification accounting unless the fair value, vesting conditions and classification of the modified award are the same immediately before and after a modification of the award has occurred. ASU 2017-09 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. An entity should apply ASU 2017-09 on a prospective basis. We elected to adopt this accounting standards update in the fourth quarter of 2017. The adoption did not have an impact on our consolidated results of operations, balance sheets, cash flows or financial disclosures.


v.	Recent Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). The amendments in ASU 2014-09 provide for a single, principles-based model for revenue recognition that replaces the existing revenue recognition guidance. In August 2015, the FASB issued Accounting Standards Updated 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date, to defer the effective date of ASU 2014-09 for one year. Therefore, the new guidance will be effective for annual and interim periods beginning after December 15, 2017 and will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. In March and April 2016, the FASB issued Accounting Standards Update No. 2016-08 and No. 2016-10, Revenue from Contracts with Customers (Topic 606) and Principal versus Agent Considerations and Identifying Performance Obligations and Licensing, respectively (together, “ASU 2016-08/10”). The amendments in ASU 2016-08/10 state that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The effective date and transition requirements for the amendments in ASU 2016-08/10 are the same as the effective date and transition requirements in ASU 2015-14. It permits the use of either a retrospective or cumulative effect transition method and early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. We have undertaken a review of the Company’s key revenue drivers as it relates to ASU 2014-9. The Company has adopted these standards as of January 1, 2018 and has selected a modified retrospective transition method for the adoption. Based on our evaluation of our revenue streams, the Company has determined that there will not be a material impact as of the date of adoption between the new revenue standard and how we previously recognized revenue, and will not have a material effect on our consolidated results of operations, balance sheets, and cash flows. The Company has finalized what additional information will be disclosed and determined the overall level of disclosure related to revenue recognition will increase.

including interim periods within those fiscal years, with early adoption permitted. An entity should apply ASU 2016-02 using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and early adoption is permitted; however, the FASB recently proposed an optional transition method for which entities would still adopt ASU 2016-02 using a modified retrospective transition method, but would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. We note that with the adoption of the amendments in ASU 2016-02, operating leases related to certain of our land leases with durations greater than twelve months will require recognition in our consolidated balance sheet under ASU 2016-02. This could have a material effect on our consolidated balance sheets, but we do not anticipate this will have a material effect on our results of operations or cash flows.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ("ASU 2018-02"). The amendments in ASU 2018-02 allow entities to reclassify from accumulated other comprehensive income (AOCI) to retained earnings "stranded" tax effects resulting from passage of the Act. An entity that elects to reclassify these amounts must reclassify stranded tax effects related to the change in federal tax rate for all items accounted for in other comprehensive income (e.g., employee benefits, cumulative translation adjustments). Entities may also

Notes to Consolidated Financial Statements

elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal rate (e.g., state taxes). However, because the amendments only relate to the reclassification of the income tax effects of the Act, the underlying guidance requiring the effect of a change in tax laws or rates be included in income from operations is not affected. Upon adoption of ASU 2018-02, entities will be required to disclose their policy for releasing the income tax effects from AOCI. Entities that elect to reclassify the income tax effects of the Act from AOCI to retained earnings must disclose that such an election was made, including a description of reclassified tax effects. ASU 2018-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period for which financial statements, interim or annual, have not been issued or made available for issuance. The amendments in 2018-02 may be applied retrospectively to each period in which the effect of the Act is recognized or an entity may elect to apply the amendments in the period of adoption. The Company anticipates early adoption of these standards in first quarter of 2018, and has not selected an adoption method. We are still evaluating the effects of adopting ASU 2018-02, and this could have a material impact resulting from a reclassification from AOCI to retained earnings on our consolidated balance sheets, comprehensive income, and equity. However, we do not anticipate an impact to our consolidated statement of operations and cash flows.

4.	Goodwill and Intangible Assets

We assess goodwill and intangible assets with indefinite lives for impairment annually during the fourth quarter or when an event occurs or circumstances change that would indicate potential impairment. For the year ended December 31, 2017, we performed a qualitative analysis of our goodwill and indefinite-lived intangible assets and noted no indicators of impairment. Through that analysis, we determined that it is not likely that the carrying value of goodwill and indefinite-lived intangible assets exceeded their respective fair values. As of December 31, 2017 and 2016, the carrying amount of goodwill was $630.2 million.

As of December 31, 2017 and 2016, intangible assets, net consisted of the following:



	As of December 31, 2017
(Amounts in thousands, except years)	Weighted-Average Remaining Amortization Period (Years)	Gross Carrying Value		Accumulated Amortization			Net Carrying Value

5.	Noncontrolling Interests, Partnerships and Joint Ventures

Redeemable Noncontrolling Interests

Redeemable noncontrolling interests represent the non-affiliated parties' share of the assets of the Partnership Parks that are less than wholly-owned: SFOT, SFOG and Six Flags White Water Atlanta, which is owned by the partnership that owns SFOG.

The following table presents a rollforward of redeemable noncontrolling interests in the Partnership Parks:



(Amounts in thousands)	SFOT			SFOG			Total

See Note 15 for a description of the partnership arrangements applicable to the Partnership Parks, the accounts of which are included in the accompanying consolidated financial statements. As of December 31, 2017, the redemption value of the noncontrolling partnership units in SFOT and SFOG was approximately $227.6 million and $266.8 million, respectively.


6.	Derivative Financial Instruments

In April 2014, we entered into three separate interest rate swap agreements (collectively, the "Interest Rate Swap Agreements") with an aggregate notional amount of $200.0 million to mitigate the risk of an increase in the LIBOR interest rate

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

above the 0.75% minimum LIBOR rate in effect on the Term Loan B. The term of the Interest Rate Swap Agreements began in June 2014 and expired in December 2017. Upon execution, we designated and documented the Interest Rate Swap Agreements as cash flow hedges.

On March 31, 2017, the Interest Rate Swap Agreements were de-designated due to a change in the forecasted borrowings. The Interest Rate Swap Agreements continued to serve as economic hedges and provide protection against rising interest rates for the Amended and Restated Term Loan B (as defined in Note 7) during the year ended December 31, 2017. Subsequent to the de-designation, the amounts recorded in accumulated other comprehensive loss have been amortized into earnings through the original December 2017 maturity date. As of the year ended December 31, 2017, the Interest Rate Swap Agreements have expired and all related amounts previously held as derivative assets and liabilities on our consolidated balance sheets and previously recorded into our accumulated other comprehensive income ("AOCI") have been realized in earnings.

By utilizing a derivative instrument to hedge our exposure to LIBOR rate changes, we were exposed to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. To mitigate this risk, the hedging instruments were placed with counterparties that we believed posed minimal credit risk. Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates, commodity prices or currency exchange rates. We managed the market risk associated with the Interest Rate Swap Agreements by establishing and monitoring parameters that limited the types and degree of market risk that we may have undertaken. We hold and issue derivative instruments for risk management purposes only and do not utilize derivatives for trading or speculative purposes.

We recorded derivative instruments at fair value on our consolidated balance sheets with the effective portion of all cash flow designated derivatives deferred in other comprehensive income and the ineffective portion, if any, recognized immediately in earnings. Our derivatives were measured on a recurring basis using Level 2 inputs. The fair value measurements of our derivatives were based on market prices that generally were observable for similar assets or liabilities at commonly quoted intervals. Derivative assets and derivative liabilities that had maturity dates equal to or less than twelve months from the balance sheet date were included in prepaid and other current assets and other accrued liabilities, respectively. Derivative assets and derivative liabilities that had maturity dates greater than twelve months from the balance sheet date were included in deposits and other assets and other long-term liabilities, respectively.

As of December 31, 2017, we have no remaining derivative instruments recorded in our consolidated balance sheets, and as of December 31, 2016, derivative instruments designated as cash flow hedges recorded at fair value in our consolidated balance sheets as current other accrued liabilities were $0.9 million.

Prior to the March 2017 de-designation, effective changes in the fair value of derivatives that were designated as hedges were recorded in AOCI on the consolidated balance sheet when in qualifying relationships and were reclassified to interest expense when the forecasted transaction took place. Ineffective changes, if any, and changes in the fair value of derivatives that were not designated as hedges were recorded directly in interest expense and other expense, net, respectively.

Losses before tax on derivatives not designated as hedging instruments included in our consolidated statements of operations were $0.1 million for the year ended December 31, 2017. There were no gains or losses before taxes on derivatives not designated as hedging instruments for the years ended December 31, 2016 and 2015.

Gains and losses before tax on derivatives that were designated as cash flow hedges included in our consolidated statements of operations for the years ended December 31, 2017, 2016 and 2015 were as follows:



	Gain / (Loss) Recognized in AOCI (Effective Portion)								Loss Reclassified from AOCI into Operations (Effective Portion)									Gain / (Loss) Recognized in Operations on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
(Amounts in thousands)	2017		2016			2015			2017			2016			2015			2017		2016			2015
Interest Rate Swap Agreements	57		(944		)	(2,671		)	(769		)	(1,716		)	(1,799		)	30		(45		)	—
Total	$	57	$	(944	)	$	(2,671	)	$	(769	)	$	(1,716	)	$	(1,799	)	$	30	$	(45	)	$	—

As of December 31, 2017, there are no remaining unrealized gains or losses associated with the Interest Rate Swap Agreements that will be reclassified from AOCI to operations.

Credit Facility

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

On December 20, 2011, we entered into a $1,135.0 million credit agreement (the "2011 Credit Facility") with several lenders including Wells Fargo Bank National Association, as administrative agent, and related loan and security documentation agents. The 2011 Credit Facility was comprised of a 5-year $200.0 million revolving credit loan facility (the "Revolving Loan"), a 5-year $75.0 million Tranche A Term Loan facility ("Term Loan A") and a 7-year $860.0 million Tranche B Term Loan facility ("Term Loan B" and together with the Term Loan A, the "Term Loans"). In certain circumstances, the Term Loan B could be increased by $300.0 million. The proceeds from the $935.0 million Term Loans were used, along with $15.0 million of existing cash, to retire the $950.0 million senior term loan from the prior facility. Interest on the 2011 Credit Facility accrued based on pricing rates corresponding with the senior secured leverage ratios of Six Flags Theme Parks Inc. ("SFTP") as set forth in the credit agreement.

On December 21, 2012, we entered into an amendment to the 2011 Credit Facility (the "2012 Credit Facility Amendment") that among other things, permitted us to (i) issue $800.0 million of senior unsecured notes (see 2021 Notes below), (ii) use $350.0 million of the proceeds of the senior unsecured notes to repay the $72.2 million that was outstanding under the Term Loan A and $277.8 million of the outstanding balance of the Term Loan B, (iii) use the remaining $450.0 million of proceeds for share repurchases and other corporate matters and (iv) reduce the interest rate payable on the Term Loan B by 25 basis points.

On December 23, 2013, we entered into an amendment to the 2011 Credit Facility (the "2013 Credit Facility Amendment") that reduced the overall borrowing rate on the Term Loan B by 50 basis points through (i) a 25 basis point reduction in the applicable margin from LIBOR plus 3.00% to LIBOR plus 2.75% and (ii) a 25 basis point reduction in the minimum LIBOR rate from 1.00% to 0.75%. Additionally, the 2013 Credit Facility Amendment permitted us to use up to $200.0 million of our excess cash on hand, over time, for general corporate purposes, including potential share repurchases.

On June 30, 2015, we amended and restated the 2011 Credit Facility (as amended by the 2012 Credit Facility Amendment and the 2013 Credit Facility Amendment, the "Amended and Restated Credit Facility"). The Amended and Restated Credit Facility is comprised of a $250.0 million revolving credit loan facility (the "Amended and Restated Revolving Loan") and a $700.0 million Tranche B Term Loan facility (the "Amended and Restated Term Loan B"). Additionally, the Amended and Restated Credit Facility increased the additional flexibility under the Amended and Restated Term Loan B to $350.0 million. In connection with entering into the Amended and Restated Credit Facility, we repaid the outstanding Term Loan B and we recognized a loss on debt extinguishment of $6.6 million. The remaining proceeds from the Amended and Restated Credit Facility were used for share repurchases and payment of refinancing fees.

On June 16, 2016, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points through a reduction in the applicable margin from LIBOR plus 2.75% to LIBOR plus 2.50%. We capitalized $1.0 million of debt issuance costs directly associated with the issuance of this amendment. Additionally, we used $150.0 million of the proceeds from the issuance of the 2024 Notes discussed below to reduce our borrowings under the Amended and Restated Term Loan B and recognized a loss on debt extinguishment of $2.4 million. The paydown of borrowings under the Amended and Restated Term Loan B eliminated any required quarterly amortization payments thereunder until its final maturity on June 30, 2022.

On December 20, 2016, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points through a reduction in the applicable margin from LIBOR plus 2.50% to LIBOR plus 2.25%, with the elimination of the minimum LIBOR rate requirement. We capitalized a nominal amount of debt issuance costs directly associated with the issuance of this amendment and recognized a loss on debt extinguishment of $0.5 million.

On June 21, 2017, we entered into an amendment to the Amended and Restated Credit Facility that reduced the overall borrowing rate on the Amended and Restated Term Loan B by 25 basis points through a reduction in the applicable margin from LIBOR plus 2.25% to LIBOR plus 2.00%. We capitalized $0.5 million of debt issuance costs directly associated with the issuance of this amendment and recognized a loss on debt extinguishment of $0.2 million.

As of December 31, 2017 and 2016, no advances under the Amended and Restated Revolving Loan were outstanding (excluding amounts reserved for letters of credit in the amount of $18.7 million and $19.7 million, respectively). Interest on the Amended and Restated Revolving Loan accrues at an annual rate of LIBOR plus an applicable margin with an unused commitment fee based on our senior secured leverage ratio. As of December 31, 2017 and 2016, the Amended and Restated Revolving Loan unused commitment fee was 0.375%. The principal amount of the Amended and Restated Revolving Loan is due and payable on June 30, 2020.

As of December 31, 2017 and 2016, $544.8 million was outstanding under the Amended and Restated Term Loan B. Interest on the Amended and Restated Term Loan B accrues at an annual rate of LIBOR plus an applicable margin, based on our consolidated leverage ratio. In April 2014, we entered into the Interest Rate Swap Agreements with a notional amount of $200.0

million to mitigate the risk of an increase in the LIBOR interest rate above the 0.75% minimum LIBOR rate in effect on the Term Loan B. The Interest Rate Swap Agreements continued to mitigate an increase in the LIBOR rate in effect on the Amended and Restated Term Loan B through December 2017. See Note 6 for further discussion. As of December 31, 2017 and 2016, the applicable interest rate on the Amended and Restated Term Loan B was 3.36% and 3.16%, respectively. Beginning on September 30, 2015, the Amended and Restated Term Loan B became payable in equal quarterly installments of $1.8 million, but the $150.0 million prepayment with proceeds from the 2024 Notes discussed below was applied to the quarterly amortization payments and eliminated the future quarterly amortization payments until maturity. All remaining outstanding principal of the Amended and Restated Term Loan B is due and payable on June 30, 2022.

Amounts outstanding under the Amended and Restated Credit Facility are guaranteed by Holdings, Six Flags Operations Inc. ("SFO") and certain of the domestic subsidiaries of SFTP (collectively, the "Loan Parties"). The Amended and Restated Credit Facility is secured by a first priority security interest in substantially all of the assets of the Loan Parties. The Amended and Restated Credit Facility agreement contains certain representations, warranties, affirmative covenants and financial covenants (specifically, (i) a minimum interest coverage covenant and (ii) a maximum senior leverage maintenance covenant). In addition, the Amended and Restated Credit Facility agreement contains restrictive covenants that, subject to certain exceptions, limit or restrict, among other things, the incurrence of indebtedness and liens, fundamental changes, restricted payments, capital expenditures, investments, prepayments of certain indebtedness, transactions with affiliates, changes in fiscal periods, modifications of certain documents, activities of the Company and SFO and hedging agreements, subject, in each case, to certain carve-outs.

2021 Notes, 2024 Notes and 2027 Notes

On December 21, 2012, Holdings issued $800.0 million of 5.25% senior unsecured notes due January 15, 2021 (the "2021 Notes"). The proceeds from the 2021 Notes were used to repay the $72.2 million that was outstanding under the Term Loan A and to repay $277.8 million of the outstanding balance of the Term Loan B. The remaining proceeds were used for share repurchases. Interest payments of $21.0 million were due semi-annually on January 15 and July 15 (except in 2013 when we only made one interest payment of $22.3 million on July 15).

On June 16, 2016, Holdings issued $300.0 million of 4.875% senior unsecured notes due July 31, 2024 (the "2024 Notes"). We capitalized $4.7 million of debt issuance costs directly associated with the issuance of the 2024 Notes. We used approximately $150.0 million of the proceeds from the issuance of the 2024 Notes to reduce our borrowings under the Amended and Restated Term Loan B. We used the remaining net proceeds of the sale of the 2024 Notes for general corporate and working capital purposes, which primarily included repurchases of our common stock.

On April 13, 2017, we issued an additional $700.0 million of 4.875% Senior Notes due 2024 (the "2024 Notes Add-on"). We capitalized $3.9 million of debt issuance costs directly associated with the issuance of the 2024 Notes Add-on. Interest payments of $24.4 million for the 2024 Notes and the 2024 Notes Add-on are due semi-annually on January 31 and July 31 of each year, with the exception of the first payment for the 2024 Notes on January 31, 2017, which was $9.1 million.

On April 13, 2017, we issued $500.0 million of 5.500% Senior Notes due 2027 (the "2027 Notes"). We capitalized $2.6 million of debt issuance costs directly associated with the issuance of the 2027 Notes. Interest payments of $13.8 million are due semi-annually on April 15 and October 15 of each year, with the exception of the first payment on October 15, 2017, which was $13.9 million.

A portion of the net proceeds from the issuance of the 2024 Notes Add-on and 2027 Notes was used to redeem all of the outstanding 2021 Notes and to satisfy and discharge the indenture governing the 2021 Notes, including to pay the accrued and unpaid interest to the redemption date, the related redemption premium on the 2021 Notes, and related fees and expenses. The remaining net proceeds were used for general corporate and working capital purposes, which primarily included repurchases of our common stock. In connection with the redemption of all of the outstanding 2021 Notes, in the second quarter of 2017 we recognized a loss on debt extinguishment of $36.9 million.

The 2024 Notes, the 2024 Notes Add-on and the 2027 Notes are guaranteed by the Loan Parties. The 2024 Notes, the 2024 Notes Add-on and the 2027 Notes contain restrictive covenants that, subject to certain exceptions, limit or restrict, among other things, the ability of the Loan Parties to incur additional indebtedness, create liens, engage in mergers, consolidations and other fundamental changes, make investments, engage in transactions with affiliates, pay dividends and repurchase capital stock. The 2024 Notes, the 2024 Notes Add-on and the 2027 Notes contain certain events of default, including payment defaults, breaches of covenants and representations, cross defaults to other material indebtedness, judgment, and changes of control and bankruptcy events of default.

HWP Refinance Loan

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

On November 5, 2007, HWP Development, LLC, which is one of our wholly-owned subsidiaries (“HWP"), entered into a $33.0 million term loan (the "Refinance Loan"). Borrowings under the Refinance Loan bore interest at 6.72%, with payments of principal and interest due monthly. Prior to repayment of the Refinance Loan, HWP was subject to various covenants under the Refinance Loan that placed certain restrictions limiting or prohibiting engaging in certain types of transactions. Pursuant to the Refinance Loan, HWP deposited certain amounts into escrow, including $3.9 million as of December 31, 2016. On September 29, 2017, we repaid all amounts outstanding under the Refinance Loan and on October 13, 2017, all amounts previously held in escrow were released.

Notes to Consolidated Financial Statements

During the year ended December 31, 2017, we recognized a reversal of stock-based compensation expense related to the Long-Term Incentive Plan of $23.0 million, and during the years ended December 31, 2016 and 2015, we recognized stock-based compensation expense of $116.0 million and $55.9 million, respectively.

As of December 31, 2017, options to purchase approximately 5,185,000 shares of common stock of Holdings and approximately 12,000 shares of restricted stock or restricted stock units were outstanding under the Long-Term Incentive Plan and approximately 5,498,000 shares were available for future grant.

Stock Options

Options granted under the Long-Term Incentive Plan are designated as either incentive stock options or non-qualified stock options. Options are generally granted with an exercise price equal to the fair market value of the common stock of Holdings on the date of grant. While certain stock options are subject to acceleration in connection with a change in control, options are generally cumulatively exercisable in four equal annual installments commencing one year after the date of grant with a ten-year term. Generally, the unvested portion of stock option awards is forfeited upon termination of employment. Stock option compensation is recognized over the vesting period using the graded vesting terms of the respective grant.

The estimated fair value of the majority of our options granted was calculated using the Black-Scholes option pricing valuation model. This model takes into account several factors and assumptions. The risk-free interest rate is based on the yield on United States Treasury zero-coupon issues with a remaining term equal to the expected term assumption at the time of grant. We have sufficient historical data to develop an expected term assumption and we calculated the expected term using a mid-point scenario with a one-year grant date filter to exclude grants for which vesting could not have yet occurred. Expected volatility is based three-fourths on the term-matching historical volatility of our stock and one-fourth on the weighted-average implied volatility based on forward-looking pricing data on exchange-traded options for our stock. The expected dividend yield is based on our current quarterly dividend and a three-month average stock price. The fair value of stock options on the date of grant is expensed on a straight line basis over the requisite service period of the graded vesting term as if the award was, in substance, multiple awards.

The following weighted-average assumptions were utilized in the Black-Scholes model to value the stock options granted during the years ended December 31, 2017, 2016 and 2015:



	December 31, 2017				December 31, 2016				December 31, 2015
	CEO		Employees		CEO		Employees		CEO		Employees
Risk-free interest rate	1.64	%	1.56	%	1.05	%	1.00	%	1.80	%	1.13	%
Expected life (in years)	3.85		3.85		3.85		3.85		6.25		3.91
Expected volatility	21.89	%	22.70	%	24.30	%	23.17	%	36.04	%	24.85	%
Expected dividend yield	4.22	%	4.42	%	4.47	%	4.15	%	4.28	%	4.46	%

As of December 31, 2017, there was $11.6 million of unrecognized compensation expense related to option awards. The weighted-average period over which that cost is expected to be recognized is 3.10 years.

Stock, Restricted Stock and Restricted Stock Units

Stock, restricted stock and restricted stock units granted under the Long-Term Incentive Plan may be subject to transfer and other restrictions as determined by the compensation committee of Holdings' Board of Directors. Generally, the unvested portion of restricted stock and restricted stock unit awards is forfeited upon termination of employment. The fair value of stock, restricted stock and restricted stock unit awards on the date of grant is expensed on a straight line basis over the requisite service period of the graded vesting term as if the award was, in substance, multiple awards.

During the year ended December 31, 2011, a performance award was established based on our goal to achieve Modified EBITDA of $500 million by 2015 (the "2015 Performance Award"). "Modified EBITDA” is defined as the Company’s consolidated income from continuing operations: excluding the cumulative effect of changes in accounting principles; discontinued operations gains or losses; income tax expense or benefit; restructure costs or recoveries; reorganization items (net); other income or expense; gain or loss on early extinguishment of debt; equity in income or loss of investees; interest expense (net); gain or loss on disposal of assets; gain or loss on the sale of investees; amortization; depreciation; stock-based compensation; and fresh start accounting valuation adjustments. Based on the results of operations for the years ended December 31, 2014 and 2015, the 2015 Performance Award was issued, resulting in the issuance of 1,511,100 shares and 1,314,000 shares, plus associated dividend equivalent rights ("DERs"), in February 2015 and 2016, respectively. For the year ended December 31, 2016, we recognized a reduction in stock-based compensation expense of $1.6 million as a result of the decline in the closing market price of Holdings' common stock on the date of issuance in February 2016 relative to December 31, 2015.

During the year ended December 31, 2014, a performance award was established based on our goal to achieve Modified EBITDA of $600 million by 2017 (the "2017 Performance Award"). The compensation committee of Holdings' Board of Directors determined that, since the incremental investment in the new Mexico waterpark was not planned when the 2017 Performance Award goal was established, the 2017 Performance Award goal would be increased by an amount based on our cost of capital times the incremental investment, prorated for the number of months in 2017 the waterpark was open less pre-opening expenses incurred in 2017. On this basis, the 2017 Performance Award goal increased by $1.1 million to $601.1 million during 2017. If the goal had been achieved in 2017, an aggregate payout under this award to key employees would have been approximately 2,300,000 shares, plus DERs. During the third quarter of 2016, we determined that achievement of the Modified EBITDA performance goal was probable by 2017; however, the adverse weather and natural disasters experienced during the summer months of 2017 prevented us from achieving this goal and, in accordance with FASB ASC Topic 718, Stock Compensation, full or partial achievement of the 2017 Performance Award was no longer deemed probable in the third quarter of 2017. We are currently recognizing stock-based compensation expense based on the probable late achievement of the 2017 Performance Award in 2018, which would result in half of the aggregate payout being awarded. To reflect the probable late achievement of the 2017 Performance Award in 2018, we reduced previously recognized stock-based compensation expense during the year ended December 31, 2017 by $66.7 million, plus an additional $6.2 million for the associated DERs.

In accordance with FASB ASC Topic 718, Stock Compensation, we have accrued the following amounts for stock-based compensation expense related to the 2017 Performance Awards and related DERs for the years ended December 31, 2017 and 2016:



	December 31,
(Amounts in thousands)	2017		2016
Project 600 Performance Award	$	54,877	$	91,408
Project 600 Performance Award - DERs	7,635		$	11,039
Total Project 600 Performance Award Accrued Expense	$	62,512	$	102,447

Based on the closing market price of Holdings' common stock on the last trading day of the quarter ended December 31, 2017, the total unrecognized compensation expense related to the 2017 Performance Award and the related DERs for the year ended December 31, 2017 is $24.4 million.

Notes to Consolidated Financial Statements

During the year ended December 31, 2016, an additional performance award was established based on our aspirational goal to achieve Modified EBITDA of $750 million by 2020 (the "2020 Performance Award"). The aggregate payout under the performance award to key employees if the target is achieved in 2020 would be 900,000 shares plus associated DERs but could be more or less depending on the level of achievement and the timing thereof. There has been no stock-based compensation expense recorded for this performance award because it is not deemed probable that we will achieve the specified performance targets as of December 31, 2017. Based on the closing market price of Holdings' common stock on the last trading day of the quarter ended December 31, 2017, the total unrecognized compensation expense related to this award at target achievement in 2020 is $59.9 million that will be expensed over the service period if it becomes probable of achieving the performance condition. We will continue to evaluate the probability of achieving the performance condition going forward and record the appropriate expense if necessary

Exclusive of the unrecognized stock-based compensation expense related to the 2017 Performance Award and the 2020 Performance Award discussed above, there was $0.3 million of total unrecognized stock-based compensation expense related to stock, restricted stock and restricted stock units as of December 31, 2017 that is expected to be recognized over a weighted-average period of 0.34 years.

Deferred Share Units

Non-employee directors can elect to receive the value of their annual cash retainer as a deferred share unit award ("DSU") under the Long-Term Incentive Plan whereby the non-employee director is granted DSUs in an amount equal to such director's annual cash retainer divided by the closing price of Holdings' common stock on the date of the annual stockholders meeting. Each DSU represents Holdings' obligation to issue one share of common stock. The shares are delivered approximately thirty days following the cessation of the non-employee director's service as a director of Holdings'.

DSUs generally vest consistent with the manner in which non-employee directors' cash retainers are paid. The fair value of the DSUs on the date of grant is expensed on a straight line basis over the requisite service period.

During each of the years ended December 31, 2017, 2016 and 2015, approximately 3,000 DSUs were granted at a weighted-average grant date fair value of $56.32, $54.16 and $46.60 per DSU, respectively. The total grant date fair value of DSUs granted was $0.2 million for the years ended December 31, 2017 and 2016 and $0.1 million for the year ended December 31, 2015.

As of December 31, 2017, there was no unrecognized compensation expense related to the outstanding DSUs.

Dividend Equivalent Rights

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements

On February 8, 2012, Holdings' Board of Directors granted DERs to holders of unvested stock options, at which time, approximately 10.0 million unvested stock options were outstanding. The DERs accrue dividends as of the record date of each of Holdings' dividends that will be distributed to stock option holders upon the vesting of their stock option award. Holdings will distribute the accumulated accrued dividends pursuant to the DERs in either cash or shares of common stock. Generally, holders of stock options for fewer than 1,000 shares of stock will receive their accumulated accrued dividends in cash and holders of stock options for 1,000 shares of stock or greater will receive their accumulated accrued dividends in shares of common stock. In addition, Holdings' Board of Directors granted similar DERs payable in shares of common stock if and when any shares are granted under the 2015 Performance Award, the 2017 Performance Award and the 2020 Performance Award.

Holdings' Board of Directors granted approximately 1.9 million, 1.3 million and 1.2 million additional options to the majority of our full-time employees as well as DERs in connection with such options during the years ended December 31, 2017, 2016 and 2015, respectively. Exclusive of stock-based compensation recognized for the DER grants associated with the 2015 Performance Award and 2017 Performance Award discussed above, we recorded stock-based compensation for DER grants of $4.2 million, $5.1 million and $4.5 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Employee Stock Purchase Plan

The Six Flags Entertainment Corporation Employee Stock Purchase Plan (the "ESPP") allows eligible employees to purchase Holdings' common stock at 90% of the lower of the market value of the common stock at the beginning or end of each successive six-month offering period. Amounts accumulated through participants' payroll deductions ("purchase rights") are used to purchase shares of common stock at the end of each purchase period. Pursuant to the ESPP, no more than 2,000,000 shares of common stock of Holdings may be issued. Holdings' common stock may be issued by either authorized and unissued shares, treasury shares or shares purchased on the open market. As of December 31, 2017, we had 1,739,000 shares available for purchase pursuant to the ESPP

In accordance with FASB ASC Topic 718, Stock Based Compensation, stock-based compensation related to purchase rights is recognized based on the intrinsic value of each respective six-month ESPP offering period. As of December 31, 2017 and 2016, no purchase rights were outstanding under the ESPP.

Stock-based compensation (reversal) and expense consisted of the following for the years ended December 31, 2017, 2016 and 2015:



	Year Ended December 31,
(Amounts in thousands)	2017			2016		2015

10.	Fair Value of Financial Instruments

The fair value of a financial instrument is the amount at which the instrument could be exchanged in a current transaction between willing parties. We use a market approach for our recurring fair value measurements, and we endeavor to use the best information available. Accordingly, valuation techniques that maximize the use of observable impacts are favored. The following table and accompanying information present the estimated fair values and classifications of our financial instruments in accordance with FASB ASC Topic 820, Fair Value Measurement, as of December 31, 2017 and 2016:



	As of
	December 31, 2017						December 31, 2016
(Amounts in thousands)	Carrying Value			Fair Value			Carrying Value			Fair Value
Financial assets (liabilities):
Restricted-use investment securities	$	—		$	—		$	3,926		$	3,926
Interest Rate Swap Agreements	—			—			(871		)	(871		)
Long-term debt (including current portion)	(2,021,178		)	(2,057,083		)	(1,653,647		)	(1,679,525		)

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:


•	The carrying values of cash and cash equivalents, accounts receivable, notes receivable, accounts payable and accrued liabilities approximate fair value because of the short maturity of these instruments.

Table of Contents

SIX FLAGS ENTERTAINMENT CORPORATION

Notes to Consolidated Financial Statements


•	Restricted-use investment securities consist of interest bearing bank accounts for which their carrying value approximates their fair value because of their short term maturity. The measurement of restricted-use investment securities is considered a Level 2 fair value measurement.

•

The measurement of the fair value of derivative assets and liabilities is based on market prices that generally are observable for similar assets and liabilities at commonly quoted intervals and is considered a Level 2 fair value measurement. Derivative assets and liabilities that have maturity dates equal to or less than twelve months from the balance sheet date are included in prepaid and other current assets and other accrued liabilities, respectively. Derivative assets and liabilities that have maturity dates greater than twelve months from the balance sheet date are included in deposits and other assets and other long-term liabilities, respectively. See Note 6 for additional information on our derivative instruments and related Company policies.

In connection with emergence from Chapter 11, the Company's prepetition debt securities, primarily the prepetition notes issued by Six Flags, Inc. (which changed its corporate name to Six Flags Entertainment Corporation (Holdings) upon emergence from bankruptcy in 2010) and SFO, were extinguished. Absent an exception, a debtor recognizes cancellation of debt income ("CODI") upon discharge of its outstanding indebtedness for an amount of consideration that is less than its adjusted issue price. The Internal Revenue Code ("IRC") provides that a debtor in a bankruptcy case may exclude CODI from income but must reduce certain of its tax attributes by the amount of any CODI realized as a result of the consummation of a plan of reorganization. The amount of CODI realized by a taxpayer is the adjusted issue price of any indebtedness discharged less the sum of (i) the amount of cash paid, (ii) the issue price of any new indebtedness issued and (iii) the fair market value of any other consideration, including equity, issued. As a result of the market value of our equity upon emergence from Chapter 11 bankruptcy proceedings, we were able to retain a significant portion of our federal NOLs and state NOLs (collectively, the "Tax Attributes") after reduction of the Tax Attributes for CODI realized on emergence from Chapter 11. As a result of emergence from Chapter 11, the Company's NOLs were reduced by approximately $804.8 million of CODI.

Sections 382 and 383 of the IRC impose an annual limitation on the utilization of NOLs and other favorable Tax Attribute carryforwards that a corporation has at the time of a so-called "ownership change" within the meaning of IRC Section 382. The Company's issuance of stock pursuant to its reorganization under Chapter 11 resulted in such an ownership change. The limitation amount is the product of the value of the Company, computed under special rules that apply to a bankruptcy reorganization, and a published rate that applied for the month the Company emerged from Chapter 11. The Company's limitation amount is approximately $32.5 million for each year to which NOLs and other Tax Attribute carryforwards that existed at emergence are carried, increased by the portion of the net built-in income and gain that existed at emergence and that IRS pronouncements permit a taxpayer to treat as recognized during the five year period following the ownership change. This has allowed the Company to increase its annual limitation by approximately $696.0 million through the end of 2015. Annual limitation amounts accumulate for future use to the extent they are not utilized in a given year. As a result of the Section 382 limitation, the Company may have a cash tax liability in future years even though its deferred tax assets have not been exhausted. A subsequent ownership change could further limit the Company's utilization of NOLs and other Tax Attributes if a smaller limitation resulted from the subsequent ownership change or applied to NOLs and other Tax Attributes accumulated after emergence from Chapter 11.

Substantially all of our future taxable temporary differences (deferred tax liabilities) relate to the different financial accounting and tax depreciation methods and periods for property and equipment (20 to 25 years for financial reporting purposes and 7 to 12 years for tax reporting purposes) and intangibles. Our net operating loss carryforwards, foreign tax credits, alternative minimum tax credits, accrued insurance expenses and deferred compensation amounts represent future income tax benefits (deferred tax assets). The following table summarizes the components of deferred income tax assets and deferred tax liabilities as of December 31, 2017 and 2016:

As of December 31, 2017, we had approximately $0.3 billion and $5.6 billion of net operating loss carryforwards available for U.S. federal income tax and state income tax purposes, respectively, that expire through 2030 and 2037, respectively. We have a valuation allowance of $113.5 million and $92.3 million as of December 31, 2017 and 2016, respectively, due to uncertainties related to our ability to utilize some of our deferred tax assets before they expire. The valuation allowance at December 31, 2017 and December 31, 2016 was based on our inability to use state deferred tax assets related to NOLs that were generated in states where we no longer do business or where we have consistently not generated taxable income. The change in valuation allowance is all attributable to income from operations.

Our unrecognized tax benefit as of December 31, 2017 and 2016 was $25.7 million and $44.6 million, respectively. The change in unrecognized tax benefit was entirely driven by rate remeasurement of the Act. We classify interest and penalties attributable to income taxes as part of income tax expense. Due to the Company's NOL position, we have not accrued any penalties and interest.

Passage of the Tax Cuts and Jobs Act (H.R. 1) and Staff Accounting Bulletin No. 118

On December 22, 2017, the Tax Cuts and Jobs Act (H.R. 1) ("the Act") was signed into law by President Donald Trump. The Act contains significant changes to corporate taxation, including a reduction of the corporate tax rate from 35% to 21%, creating a territorial tax system, allowing for immediate expensing of certain qualified property, modifying or repealing many business deductions and credits, and providing other incentives. In response to the Act, on December 22, 2017 the SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), to provide guidance for companies that are not able to complete their accounting for the income tax effects of the Act in the period of enactment. The SEC Staff noted in SAB 118 that in these cases a company should continue to apply Topic 740, Income Taxes based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted. SAB 118 provides a measurement period that should not extend beyond one year from the Act enactment date for companies to complete the accounting under Topic 740. While the Company was able to make reasonable estimates of the impact of the changes to Section 162(m) of the Internal Revenue Code on our tax provision for the year ended December 31, 2017, the final impact of the Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions of the Act, and additional guidance that may be issued by the Internal Revenue Service. As a result, the Company will continue to gather additional information to determine the final impact of these changes. Additionally, due to the complexity of the new tax laws around global intangible low taxed income (“GILTI”), the Company is continuing to evaluate how the income tax provision will be accounted for under the U.S. generally accepted accounting principles wherein companies are allowed to make an accounting policy election of either (i) account for GILTI as a component of tax expense in the period in which the Company is subject to the rules (the “period cost method”), or (ii) account for GILTI in the Company’s measurement of deferred taxes (the “deferred method”). Currently, the Company has not elected a method and will only do so after its completion of the analysis of the GILTI provisions.

12.	Preferred Stock, Common Stock and Other Stockholders' Equity

Common Stock

As of December 31, 2017, the number of authorized shares of common stock was 140,000,000, of which 84,488,433 shares were outstanding, 5,498,000 shares were reserved for future issuance through our Long-Term Incentive Plan, and 1,739,000 shares were reserved for future issuance through the ESPP. Pursuant to the ESPP, Holdings' common stock may be issued by either authorized and unissued shares, treasury shares or shares purchased on the open market.

On November 20, 2013, Holdings' Board of Directors approved a new stock repurchase program that permitted Holdings to repurchase up to $500.0 million in shares of Holdings' common stock over a four-year period (the "November 2013 Stock Repurchase Plan"). Holdings fully utilized the availability under the November 2013 Stock Repurchase Plan by August 2016. Throughout the program, Holdings repurchased 11,428,000 shares at a cumulative cost of approximately $500.0 million and an average price per share of $43.75.

During the years ended December 31, 2017, 2016 and 2015, Holdings' Board of Directors declared and paid quarterly cash dividends per share of common stock as follows:



	Dividends Paid Per Share
2017:
Fourth Quarter	$	0.70
Third Quarter	$	0.64
Second Quarter	$	0.64
First Quarter	$	0.64
2016:
Fourth Quarter	$	0.64
Third Quarter	$	0.58
Second Quarter	$	0.58
First Quarter	$	0.58
2015:
Fourth Quarter	$	0.58
Third Quarter	$	0.52
Second Quarter	$	0.52
First Quarter	$	0.52

Preferred Stock

As of December 31, 2017, the number of authorized shares of preferred stock was 5,000,000, none of which have been issued or reserved for future issuance. The authorization of preferred shares empowers Holdings' Board of Directors, without further stockholder approval, to issue preferred shares with dividend, liquidation, conversion, voting or other rights which could adversely affect the voting power or other rights of the holders of Holdings' common stock. If issued, the preferred stock could also dilute the holders of Holdings' common stock and could be used to discourage, delay or prevent a change of control.

13.	Pension Benefits

As part of the acquisition of Former SFEC, we assumed the obligations related to the SFTP Defined Benefit Plan (the "SFTP Benefit Plan"). The SFTP Benefit Plan covered substantially all of SFTP's employees. During 1999, the SFTP Benefit Plan was amended to cover substantially all of our domestic full-time employees. During 2004, the SFTP Benefit Plan was further amended to cover certain seasonal workers, retroactive to January 1, 2003. The SFTP Benefit Plan permits normal retirement at age 65, with early retirement at ages 55 through 64 upon attainment of 10 years of credited service. The early retirement benefit is reduced for benefits commencing before age 62. Plan benefits are calculated according to a benefit formula based on age, average compensation over the highest consecutive five-year period during the employee's last ten years of employment and years of service. The SFTP Benefit Plan assets are invested primarily in equity and fixed income securities, as well as alternative investments, such as hedge funds. The SFTP Benefit Plan does not have significant liabilities other than benefit obligations. Under our funding policy, contributions to the SFTP Benefit Plan are determined using the projected unit credit cost method. This funding policy meets the requirements under the Employee Retirement Income Security Act of 1974.

We froze our pension plan effective March 31, 2006, pursuant to which most participants no longer earned future pension benefits. Effective February 16, 2009, the remaining participants in the pension plan no longer earned future benefits.

Obligations and Funded Status

The following table sets forth the change in our benefit plan obligation and fair value of plan assets:



	Year Ended December 31,
(Amounts in thousands)	2017			2016			2015
Change in benefit obligation:

Benefit obligation at end of period	$	218,746		$	216,571		$	223,389

Change in fair value of plan assets:
Beginning balance	$	178,375		$	173,123		$	186,131
Actual return on assets	25,240			15,949			(2,767		)
Employer contributions	6,000			6,000			6,000
Administrative fees	(1,571		)	(1,806		)	(1,730		)

Fair value of plan assets at end of period	$	190,534		$	178,375		$	173,123

Employer contributions and benefits paid in the above table include only those amounts contributed directly to, or paid directly from, plan assets. As of December 31, 2017 and 2016, the SFTP Benefit Plan's projected benefit obligation exceeded the fair value of SFTP Benefit Plan assets resulting in the SFTP Benefit Plan being underfunded by $28.2 million and $38.2 million, respectively. The underfunded amount is recognized in other long-term liabilities in our consolidated balance sheets.

We use December 31 as our measurement date. The weighted average assumptions used to determine benefit obligations are as follows:



	December 31,
	2017		2016
Discount rate	3.45	%	3.90	%
Rate of compensation increase	N/A		N/A

Net periodic benefit cost and other comprehensive income (loss)

The following table sets forth the components of net periodic benefit cost and other comprehensive income (loss):



	Year Ended December 31,
(Amounts in thousands)	2017			2016			2015
Net periodic benefit cost:
Service cost	$	1,700		$	2,400		$	2,000
Interest cost	8,283			8,901			9,116
Expected return on plan assets	(12,831		)	(12,490		)	(13,438		)
Amortization of net actuarial loss	865			931			879
Total net periodic benefit	$	(1,983	)	$	(258	)	$	(1,443	)

Other comprehensive income:
Current year actuarial gain	$	1,136		$	4,881		$	1,934
Recognized net actuarial loss	865			931			879
Total other comprehensive gain	$	2,001		$	5,812		$	2,813

As of December 31, 2017 and 2016, we have recorded $42.2 million (net of tax expense of $0.3 million) and $43.6 million (net of tax benefit of $0.3 million) in accumulated other comprehensive loss in our consolidated balance sheets, respectively.

We anticipate that $0.8 million will be amortized from accumulated other comprehensive loss into net periodic benefit cost in 2018.

The weighted average assumptions used to determine net costs are as follows:

Notes to Consolidated Financial Statements



	Year Ended December 31,
	2017		2016		2015
Discount rate	3.90	%	4.10	%	3.80	%
Rate of compensation increase	N/A		N/A		N/A
Expected return on plan assets	7.25	%	7.25	%	7.25	%
Corridor	10.00	%	10.00	%	10.00	%
Average future life expectancy (in years)	26.33		27.79		29.39

The discount rate assumption was developed based on high-quality corporate bond yields as of the measurement date. High quality corporate bond yield indices on over 500 AA high grade bonds are considered when selecting the discount rate.

The return on plan assets assumption was developed based on consideration of historical market returns, current market conditions, and the SFTP Benefit Plan's past experience. Estimates of future market returns by asset category are reflective of actual long-term historical returns. Overall, it was projected that the SFTP Benefit Plan could achieve a 7.25% net return over time based on a consistent application of the existing asset allocation strategy and a continuation of the SFTP Benefit Plan's policy of monitoring manager performance.

Description of Investment Committee and Strategy

The Investment Committee is responsible for managing the investment of SFTP Benefit Plan assets and ensuring that the SFTP Benefit Plan's investment program is in compliance with all provisions of ERISA, other relevant legislation, related SFTP Benefit Plan documents and the Statement of Investment Policy. The Investment Committee has retained several mutual funds, commingled funds and/or investment managers to manage SFTP Benefit Plan assets and implement the investment process. The investment managers, in implementing their investment processes, have the authority and responsibility to select appropriate investments in the asset classes specified by the terms of the applicable prospectus or other investment manager agreements with the SFTP Benefit Plan.

The primary financial objective of the SFTP Benefit Plan is to secure participant retirement benefits. To achieve this, the key objective in the SFTP Benefit Plan's financial management is to promote stability and, to the extent appropriate, growth in funded status. Other related and supporting financial objectives are also considered in conjunction with a comprehensive review of current and projected SFTP Benefit Plan financial requirements.

The assets of the fund are invested to achieve the greatest reward for the SFTP Benefit Plan consistent with a prudent level of risk. The asset return objective is to achieve, as a minimum over time, the passively managed return earned by market index funds, weighted in the proportions outlined by the asset class exposures in the SFTP Benefit Plan's long-term target asset allocation.

The SFTP Benefit Plan's portfolio may be allocated across several hedge fund styles and strategies.

Plan Assets

The target allocations for plan assets are 13% domestic equity securities, 57% fixed income securities, 13% international equity securities, and 17% alternative investments. Equity securities primarily include investments in large-cap companies located in the United States and abroad. Fixed income securities include bonds and debentures issued by domestic and foreign private and governmental issuers. Alternative investments are comprised of hedge fund of funds. The following table presents the categories of our plan assets and the related levels of inputs in the fair value hierarchy used to determine the fair value, as defined in Note 2(c):

14.	Earnings Per Common Share

Basic earnings per common share is computed by dividing net income attributable to Holdings' common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed by dividing net income attributable to Holdings' common stockholders by the weighted average number of common shares outstanding during the period and the effect of all dilutive common stock equivalents. In periods where there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.

For the years ended December 31, 2017, 2016 and 2015, the computation of diluted earnings per share included the effect of 1.7 million, 2.0 million and 4.4 million dilutive stock options and restricted stock units, respectively. For the years ended December 31, 2017, 2016 and 2015, the computation of diluted earnings per share excluded the effect of 0.4 million, 0.4 million and 0.2 million antidilutive stock options and restricted stock units, respectively. Earnings per common share for the years ended December 31, 2017, 2016 and 2015 was calculated as follows:

15.	Commitments and Contingencies

Partnership Parks

On April 1, 1998, we acquired all of the capital stock of Former SFEC for $976.0 million, paid in cash. In addition to our obligations under outstanding indebtedness and other securities issued or assumed in the Former SFEC acquisition, we also guaranteed certain contractual obligations relating to the Partnership Parks. Specifically, we guaranteed the obligations of the general partners of those partnerships to (i) make minimum annual distributions (including rent) of approximately $71.1 million in 2018 (subject to cost of living adjustments) to the limited partners in the Partnership Parks (based on our ownership of units as of December 31, 2017, our share of the distribution will be approximately $31.1 million) and (ii) make minimum capital expenditures at each of the Partnership Parks during rolling five-year periods, based generally on 6% of the Partnership Parks' revenues. Cash flow from operations at the Partnership Parks is used to satisfy these requirements first, before any funds are required from us. We also guaranteed the obligation of our subsidiaries to annually purchase all outstanding limited partnership units to the extent tendered by the unit holders (the "Partnership Park Put"). The agreed price for units tendered in the Partnership Park Put is based on a valuation of each of the respective Partnership Parks (the "Specified Price") that is the greater of (a) a valuation for each of the respective Partnership Parks derived by multiplying such park's weighted average four year EBITDA (as defined in the agreements that govern the partnerships) by a specified multiple (8.0 in the case of SFOG and 8.5 in the case of SFOT) and (b) a valuation derived from the highest prices previously paid for the units of the Partnership Parks by certain entities. Pursuant to the valuation methodologies described in the preceding sentence, the Specified Price for the Partnership Parks, if determined as of December 31, 2017, is $387.0 million in the case of SFOG and $485.2 million in the case of SFOT. As of December 31, 2017, we owned approximately 31.0% and 53.1% of the Georgia limited partner interests and Texas limited partner interests, respectively. Our obligations with respect to SFOG and SFOT will continue until 2027 and 2028, respectively.

In 2027 and 2028, we will have the option to purchase all remaining units in the Georgia limited partner and the Texas limited partner, respectively, at a price based on the Specified Price, increased by a cost of living adjustment. Pursuant to the 2017 annual offer, we did not purchase any units from the Georgia partnership and we purchased 0.0708 units from the Texas partnership for approximately $0.1 million in May 2017. Pursuant to the 2016 annual offer, we did not purchase any units from the Texas partnership and we purchased 0.0650 units from the Georgia partnership for approximately $0.2 million in May 2016. As we purchase additional units, we are entitled to a proportionate increase in our share of the minimum annual distributions. The maximum unit purchase obligations for 2017 at both parks aggregated approximately $494.4 million, representing approximately 69.0% of the outstanding units of SFOG and 46.9% of the outstanding units of SFOT. The $350.0 million accordion feature on the Amended and Restated Term Loan B under the Amended and Restated Credit Facility is available for borrowing for future "put" obligations if necessary.

In connection with our acquisition of the Former SFEC, we entered into the Subordinated Indemnity Agreement with certain of the Company's entities, Time Warner and an affiliate of Time Warner, pursuant to which, among other things, we transferred to Time Warner (which has guaranteed all of our obligations under the Partnership Park arrangements) record title to the corporations which own the entities that have purchased and will purchase limited partnership units of the Partnership Parks, and we received an assignment from Time Warner of all cash flow received on such limited partnership units, and we otherwise control such entities. In addition, we issued preferred stock of the managing partner of the partnerships to Time Warner. In the event of a default by us under the Subordinated Indemnity Agreement or of our obligations to our partners in the Partnership Parks, these arrangements would permit Time Warner to take full control of both the entities that own limited partnership units and the managing partner. If we satisfy all such obligations, Time Warner is required to transfer to us the entire equity interests of these entities.

We incurred $24.7 million of capital expenditures at these parks during the 2017 season and intend to incur approximately $15.6 million of capital expenditures at these parks for the 2018 season, an amount in excess of the minimum required expenditure. Cash flows from operations at the Partnership Parks will be used to satisfy the annual distribution and capital expenditure requirements, before any funds are required from us. The Partnership Parks generated approximately $77.3 million of cash in 2017 from operating activities after deduction of capital expenditures and excluding the impact of short-term intercompany advances from or payments to Holdings. As of December 31, 2017 and 2016, we had total loans receivable outstanding of $239.3 million from the partnerships that own the Partnership Parks, primarily to fund the acquisition of Six Flags White Water Atlanta, and to make capital improvements and distributions to the limited partners in prior years.

Operating Leases

We lease under long-term leases the sites of Six Flags Mexico, Six Flags Hurricane Harbor Oaxtepec, La Ronde, Waterworld Concord and a small parcel near Six Flags New England. In certain cases, rent is based upon a percentage of the

revenues earned by the applicable park. Under these rent agreements, we recognized rental expense of approximately $5.9 million for the year ended December 31, 2017 and $5.1 million for the years ended December 31, 2016 and 2015.

Total rental expense from continuing operations, including office space and park sites, was approximately $16.1 million, $12.9 million and $11.9 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Future minimum obligations under non-cancelable operating leases, including site leases, as of December 31, 2017, are summarized as follows:

License Agreements

We are party to a license agreement pursuant to which we have the exclusive right on a long term basis to theme park use in the United States and Canada (excluding the Las Vegas, Nevada metropolitan area) of all animated, cartoon and comic book characters that Warner Bros. and DC Comics have the right to license for such use. The license fee is subject to periodic scheduled increases and is payable on a per-theme park basis.

In November 1999, we entered into license agreements (collectively, the "International License Agreements") pursuant to which we have the exclusive right on a long term basis to theme parks use in Europe, Central and South America of all animated, cartoon and comic book characters that Warner Bros., DC Comics and the Cartoon Network have the right to license for such use. Under the International License Agreements, the license fee is based on specified percentages of the gross revenues of the applicable parks.

Capital Expenditures

We currently plan on spending approximately 9% of annual revenues on capital expenditures during the 2018 calendar year.

Litigation

We are party to various legal actions arising in the normal course of business, including the cases discussed below. Matters that are probable of unfavorable outcome to us and which can be reasonably estimated are accrued. Such accruals are based on information known about the matters, our estimate of the outcomes of such matters and our experience in contesting, litigating and settling similar matters. None of the actions are believed by management to involve amounts that would be material to our consolidated balance sheets, results of operations or liquidity after consideration of recorded accruals.

On January 6, 2009, a civil action against us was commenced in the State Court of Cobb County, Georgia. The plaintiff sought damages for personal injuries, including an alleged brain injury, as a result of an altercation with a group of individuals on property adjacent to SFOG on July 3, 2007. Certain of the individuals were employees of the park, but were off-duty and not acting within the course or scope of their employment with SFOG at the time the altercation occurred. The plaintiff, who had exited the park, claimed that we were negligent in our security of the premises. Four of the individuals who allegedly participated in the altercation were also named as defendants in the litigation. Our motion for summary judgment was denied by the trial court on May 19, 2011. Pursuant to the trial that concluded on November 20, 2013, the jury returned a verdict in favor of the plaintiff for $35.0 million. The jury allocated 92% of the verdict against Six Flags and the judgment was entered on February 11, 2014. A notice of appeal was filed on September 19, 2014, which our insurers pursued on Six Flags' and the insurers' behalf, and on October 2, 2014, the plaintiff filed a notice of cross appeal. On November 20, 2015, the Georgia Court of Appeals reversed the jury verdict and remanded for a new trial on both liability and damages. On December 16, 2015, the Georgia Court of Appeals denied the parties’ various motions for reconsideration. A petition for writ of certiorari in the Georgia Supreme Court was filed on behalf of Six Flags on January 19, 2016. The Six Flags petition asked the Georgia Supreme Court to grant further review and rule that Six Flags is entitled to judgment as a matter of law without the need for a new trial. On January 19, 2016, the plaintiff also filed a petition for writ of certiorari asking the Georgia Supreme Court to review the Court of Appeals’ reversal of the jury verdict. We paid the full amount of our $2.5 million self-insurance retention to our insurers. On September 6, 2016, the Georgia Supreme Court granted both parties' certiorari petitions and oral arguments were heard on February 13, 2017. On June 5, 2017, the Georgia Supreme Court affirmed in part and reversed in part the decision of the Court of Appeals and remanded the case for further proceedings consistent with the Georgia Supreme Court’s decision. The Georgia Supreme Court held that we were entitled to a new trial to determine apportionment of damages among various tortfeasors. On June 5, 2017, the trial court entered an order approving a confidential settlement agreement reached by the parties. The amount set forth in the settlement agreement will be paid by our insurance carriers.

On June 27, 2012, Wishtoyo Foundation and its Ventura Coastkeeper program, Los Angeles Coastkeeper d/b/a Santa Monica Baykeeper, and Friends of the Santa Clara River, all non-profit corporations, filed a complaint against Holdings, SFTP and Magic Mountain LLC in the United States District Court for the Central District of California seeking declaratory and injunctive relief and civil penalties under, among others, the Federal Water Pollution Control Act (more commonly known as the Clean Water Act). The plaintiffs allege that Six Flags Magic Mountain discharged water in violation of its water discharge permits into the Santa Clara River. In January 2015, the parties to the lawsuit entered into a consent decree to settle the lawsuit, and on March 26, 2015, the consent decree was approved and entered by the District Court. In connection with settlement of the lawsuit, we intend to install at Six Flags Magic Mountain an on-site infiltration basin to retain, manage and infiltrate stormwater runoff from the park in certain instances.

On July 3, 2012, a civil action was commenced against us in the Superior Court of Solano County, California. The plaintiffs sought damages for personal injuries when a guest at Six Flags Discovery Kingdom jumped on a swinging gate arm that entered a passing tram carrying the plaintiffs on July 3, 2010. On October 24, 2014, the litigation was dismissed, without prejudice, with respect to one of the plaintiffs, a minor, who may reinstate the lawsuit at any time prior to two years following the date such plaintiff reaches the age of majority. In January 2015, an agreement was reached to settle the lawsuit with the remaining plaintiffs. We previously expensed the full amount of our $2.5 million self-insurance retention plus litigation costs in connection with this incident. Based on the passage of time without ongoing litigation and the advice of counsel, the accrual was reduced.

On September 12, 2014, a civil action against us was commenced in the Circuit Court of Cook County, Illinois. The plaintiff sought damages for personal injuries after riding a water slide at Six Flags Great America. In 2015, the venue for the action was transferred to Lake County. Pursuant to the trial that concluded on April 26, 2016, the jury returned a verdict in favor of the plaintiff for $1.5 million. In May 2016 we filed a post-trial motion to vacate the jury verdict, however, on May 31, 2017, the Appellate Court of the Second District denied our appeal and we paid the judgment amount plus interest.

holders and members through the finger scan program at Six Flags Great America in Gurnee, Illinois, and seeks statutory damages, attorney's fees and an injunction. An aggrieved party under BIPA may recover (i) $1,000 if a company is found to have negligently violated BIPA or (ii) $5,000 if found to have intentionally or recklessly violated BIPA, plus reasonable attorneys' fees in each case. The program commenced at the park in the 2014 operating season. The complaint does not allege that any information was misused or disseminated. On April 7, 2017, the court certified two questions for consideration by the Illinois Appellate Court of the Second District. On June 7, 2017, the Illinois Appellate Court granted our motion to appeal. Accordingly, two questions regarding the interpretation of BIPA were certified for consideration by the Appellate Court. On December 21, 2017, the Appellate Court found in our favor, holding that the plaintiff had to allege more than a technical violation of BIPA and had to be injured in some way. We expect that the plaintiff will be filing a petition for leave to appeal to the Illinois Supreme Court by March 1, 2018. We intend to continue to vigorously defend ourselves against this litigation. Since this litigation is still in an early stage, the outcome is currently not determinable and a reasonable estimate of loss or range of loss in excess of the immaterial amount that we have recorded for this litigation cannot be made.

During 2017, four potential class action complaints were filed against Six Flags Entertainment Corporation or one of its subsidiaries. Complaints were filed on August 11, 2017 in the Circuit Court of Lake County, Illinois, on September 1, 2017 in the United States District Court for the Northern District of Georgia, on September 11, 2017 in the Superior Court of Los Angeles County, California, and on November 30, 2017 in the Superior Court of Ocean County, New Jersey. The complaints allege that we, in violation of federal law, printed more than the last five digits of a credit or debit card number on customers’ receipts, and/or the expiration dates of those cards. A willful violation may subject a company to liability for actual damages or statutory damages between $100 and $1,000 per person, punitive damages in an amount determined by a court, and reasonable attorneys’ fees, all of which are being sought by plaintiffs. The complaints do not allege that any information was misused. We intend to vigorously defend ourselves against this litigation. Since this litigation is in an early stage, the outcome is currently not determinable and a reasonable estimate of loss or range of loss cannot be made.

Tax and other contingencies

As of December 31, 2017 and 2016, we had a nominal amount of accrued liabilities for tax and other indemnification contingencies related to certain parks sold in previous years that could be recognized as recovery losses from discontinued operations in the future if such liabilities are not requested to be paid.


16.	Business Segments

We manage our operations on an individual park location basis, including operations from parks owned, managed and branded. Discrete financial information is maintained for each park and provided to our corporate management for review and as a basis for decision making. The primary performance measures used to allocate resources is Park EBITDA (defined as park-related operating earnings, excluding the impact of interest, taxes, depreciation, amortization and any other non-cash income or expenditures). Primarily all of our parks provide similar products and services through a similar process to the same class of customer through a consistent method. We also believe that the parks share common economic characteristics. Based on these factors, we have only one reportable segment—theme parks.

The following table presents segment financial information and a reconciliation of net income to Park EBITDA. Park level expenses exclude all non-cash operating expenses, principally depreciation and amortization and all non-operating expenses.

We operate a seasonal business. In particular, our theme park operations contribute most of their annual revenue during the period from Memorial Day to Labor Day each year.

During the second and third quarter of 2017, it was determined that achieving the Modified EBITDA performance target related to the 2017 Performance Award would be difficult due to adverse weather and natural disasters experienced during the summer months of 2017. However, late achievement of the Modified EBITDA performance target related to the 2017 Performance Award will be probable by the end of 2018. As a result, we recorded a reversal to stock-based compensation expense related to this award in the second and third quarters of 2017 of $27.9 million and $45.0 million, respectively, to reflect partial achievement of the 2017 Performance Award. Refer to Note 9 for further discussion.
