IPG PHOTONICS CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except share and per share data)
1. BASIS OF PRESENTATION
The accompanying unaudited consolidated financial statements have been prepared by IPG Photonics Corporation, or "IPG", "its" or the "Company". Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). The consolidated financial statements include the Company's accounts and those of its subsidiaries. All intercompany balances have been eliminated in consolidation. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2015.
In the opinion of the Company's management, the unaudited financial information for the interim periods presented reflects all adjustments necessary for a fair presentation of the Company's financial position, results of operations and cash flows. The results reported in these consolidated financial statements are not necessarily indicative of results that may be expected for the entire year.
The Company has evaluated subsequent events through the time of filing this Quarterly Report on Form 10-Q with the SEC.
2. RECENT ACCOUNTING PRONOUNCEMENTS
In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. The impact that the standard will have on the Company's consolidated financial statements will depend upon certain criteria including the timing of the exercise and release of equity instruments, the value realized upon exercise or release of equity instruments and the fair value of the equity instruments when they were granted. The excess tax benefit from the exercise of equity instruments was $3,030 and $5,665 for the six months ended June 30, 2016 and 2015, respectively.
In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"). The standard requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. The Company is currently evaluating the impact that the standard will have and does not expect it to have a material impact on its consolidated financial statements upon adoption.
In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"). The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. The Company is currently evaluating the impact that the standard will have and does not expect it to have a material impact on its consolidated financial statements upon adoption.
In November 2015, the FASB issued amended guidance that clarifies that in a classified statement of financial position, an entity shall classify deferred tax liabilities and assets as non-current amounts. The new guidance supersedes ASC 740-10-45-5 which required the deferred tax assets and liabilities for a particular tax jurisdiction be allocated between current and non-current deferred tax assets for that tax jurisdiction on a pro rata basis. The new standard will become effective for the Company's fiscal year beginning January 1, 2017. The Company has determined that the standard will not have a material impact on its consolidated financial statements upon adoption. Current deferred tax assets at June 30, 2016 and December 31, 2015 were $24,477 and $20,346, respectively. Current deferred tax liabilities at June 30, 2016 and December 31, 2015 were $4,152 and $3,190, respectively.
In May 2014, the FASB issued Accounting Standards Update No. 2014-09 ("ASU 2014-09") "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)", and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the
consideration to which the entity expects to be entitled to in exchange for those goods or services. As currently issued and
amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods

within that reporting period, though early adoption is permitted for annual reporting periods beginning after December 15, 2016. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on its consolidated financial statements and does not expect it to have a material impact on its consolidated financial statements upon adoption.

It also excludes 95,100 and 52,300 shares, of which, includes RSUs of 31,300 and 41,700 and PSUs of 6,400 and 4,400 for the six months ended June 30, 2016 and 2015, respectively, because the effect would be anti-dilutive.
7. DERIVATIVE FINANCIAL INSTRUMENTS
Derivative instruments The Company's primary market exposures are to interest rates and foreign exchange rates. The Company uses certain derivative financial instruments to help manage these exposures. The Company executes these instruments with financial institutions it judges to be credit-worthy. The Company does not hold or issue derivative financial instruments for trading or speculative purposes.
The Company recognizes all derivative financial instruments as either assets or liabilities at fair value in the consolidated balance sheets. The Company has no derivatives that are not accounted for as a hedging instrument.
Cash flow hedges The Company entered into a cash flow hedge which is an interest rape swap associated with a new long-term note issued during the second quarter of 2016 that will terminate with long-term note in May 2023. The Company previously had a cash flow hedge which was an interest rate swap associated with a U.S. long-term note which matured in June 2015. The fair value amounts in the consolidated balance sheet related to the interest rate swaps were:

8. FAIR VALUE MEASUREMENTS
The Company's financial instruments consist of cash equivalents, short-term investments, accounts receivable, auction rate securities, accounts payable, drawings on revolving lines of credit, long-term debt, contingent purchase consideration and interest rate swaps.
The valuation techniques used to measure fair value are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.
The carrying amounts of cash equivalents, short-term investments, accounts receivable, accounts payable, drawings on revolving lines of credit, the long-term notes and interest rate swaps are considered reasonable estimates of their fair market value, due to the short maturity of most of these instruments or as a result of the competitive market interest rates, which have been negotiated.
The following table presents information about the Company's assets and liabilities measured at fair value:

Short-term investments are recorded at book value. Unrealized gains or losses are not recorded since these investments are considered held-to-maturity and consist of liquid investments including U.S. government and government agency notes, corporate notes, commercial paper and certificates of deposit with original maturities of greater than three months but less than one year. The fair value of these investments as of June 30, 2016 and December 31, 2015 was $126,759 and $106,375, respectively, which represents an unrealized loss of $35 and $209, respectively, as compared to the book value recorded on the Consolidated Balance Sheets for the same periods.
The fair value of the auction rate securities considered prices observed in inactive secondary markets for the securities held by the Company.
The fair value of accrued contingent purchase consideration incurred was determined using an income approach at the acquisition date and reporting date. That approach is based on significant inputs that are not observable in the market. Key assumptions include assessing the probability of meeting certain milestones required to earn the contingent purchase consideration.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion in conjunction with our consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward looking statements that are based on management's current expectations, estimates and projections about our business and operations. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements. See "Cautionary Statement Regarding Forward-Looking Statements."
Overview
We develop and manufacture a broad line of high-performance fiber lasers, fiber amplifiers and diode lasers that are used in numerous applications, primarily in materials processing. We sell our products globally to original equipment manufacturers ("OEMs"), system integrators and end users. We market our products internationally primarily through our direct sales force.
We are vertically integrated such that we design and manufacture most of our key components used in our finished products, from semiconductor diodes to optical fiber preforms, finished fiber lasers and amplifiers. We also manufacture certain complementary products used with our lasers, including optical delivery cables, fiber couplers, beam switches, optical processing heads and chillers. In addition, we offer laser-based systems for certain markets and applications.
Factors and Trends That Affect Our Operations and Financial Results
In reading our financial statements, you should be aware of the following factors and trends that our management believes are important in understanding our financial performance.
Net sales. We derive net sales primarily from the sale of fiber lasers and amplifiers. We also sell diode lasers, communications systems, laser systems and complementary products. We sell our products through our direct sales organization and our network of distributors and sales representatives, as well as system integrators. We sell our products to OEMs that supply materials processing laser systems, communications systems, medical laser systems and other laser systems for advanced applications to end users. We also sell our products to end users that build their own systems which incorporate our products or use our products as an energy or light source. Our scientists and engineers work closely with OEMs, systems integrators and end users to analyze their system requirements and match appropriate fiber laser or amplifier specifications. Our sales cycle varies substantially, ranging from a period of a few weeks to as long as one year or more, but is typically several months.
Sales of our products generally are recognized upon shipment, provided that no obligations remain and collection of the receivable is reasonably assured. Our sales typically are made on a purchase order basis rather than through long-term purchase commitments.
We develop our products to standard specifications and use a common set of components within our product architectures. Our major products are based upon a common technology platform. We continually enhance these and other products by improving their components and developing new components and new product designs.
The average selling prices of our products generally decrease as the products mature. These decreases result from factors such as decreased manufacturing costs and increases in unit volumes, increased competition, the introduction of new products and market share considerations. In the past, we have lowered our selling prices in order to penetrate new markets and applications. Furthermore, we may negotiate discounted selling prices from time to time with certain customers that purchase multiple units.
Gross margin. Our total gross margin in any period can be significantly affected by total net sales in any period, by product mix, that is, the percentage of our revenue in the period that is attributable to higher or lower-power products and the mix of sales between laser and amplifier sources and complete systems, by sales mix between OEM customers who purchase devices from us in high unit volumes and other customers, by mix of sales in different geographies and by other factors, some of which are not under our control.
Our product mix affects our margins because the selling price per watt is generally higher for mid-power devices and certain specialty products than for high-power devices and certain pulsed lasers sold in large volumes. The overall cost of high-power lasers may be partially offset by improved absorption of fixed overhead costs associated with sales of larger volumes of higher-power products because they use a greater number of optical components and drive economies of scale in manufacturing. Also, the profit margins on systems can be lower than margins for our laser and amplifier sources, depending on the configuration, volume and competitive forces, among other factors.

13


The mix of sales between OEM customers and other customers can affect gross margin because we provide sales price discounts on products based on the number of units ordered. As the number of OEM customers increases and the number of units ordered increases, the average sales price per unit will be reduced. We expect that the impact of reduced sales price per unit will be offset by the manufacturing efficiency provided by high unit volume orders, but the timing and extent of achieving these efficiencies may not always match the mix of sales in any given time period or be realized at all.
We also regularly review our inventory for items that are slow-moving, have been rendered obsolete or determined to be excess. Any write-off of such slow-moving, obsolete or excess inventory affects our gross margins. For example, we recorded provisions for inventory totaling $5.8 million and $3.7 million for the three months ended June 30, 2016 and 2015, respectively, and $15.4 million, $11.3 million and $15.1 million for the years ended December 31, 2015, 2014 and 2013, respectively.
Sales and marketing expense. We expect to continue to expand our worldwide direct sales organization, build and expand applications centers, hire additional personnel involved in marketing in our existing and new geographic locations as well as for expansions in our product line, increase the number of units for demonstration purposes and otherwise increase expenditures on sales and marketing activities in order to support the growth in our net sales. As such, we expect that our sales and marketing expenses will increase in the aggregate.
Research and development expense. We plan to continue to invest in research and development to improve our existing components and products and develop new components, products, systems and applications technology. The amount of research and development expense we incur may vary from period to period. In general, if net sales continue to increase we expect research and development expense to increase in the aggregate.
General and administrative expense. We expect our general and administrative expenses to increase as we continue to invest in systems and resources in management, finance, legal, information technology, human resources and administration to support our worldwide operations. Legal expenses vary from quarter to quarter based primarily upon the level of litigation and transaction activities.
Foreign Exchange. Because we are a U.S. based company doing business globally, we have both translational and transactional exposure to fluctuations in foreign currency exchange rates. Changes in the relative exchange rate between the U.S. dollar and the foreign currencies in which our subsidiaries operate directly affects our sales, costs and earnings. Differences in the relative exchange rates between where we sell our products and where we incur manufacturing and other operating costs (primarily in the U.S., Germany and Russia) also affects our costs, and earnings. Certain currencies experiencing significant exchange rate fluctuations like the Euro, the Russian Ruble, the Japanese Yen and Chinese Yuan have had and could have an additional significant impact on our sales, costs and earnings. Our ability to adjust the foreign currency selling prices of products in response to changes in exchange rates is limited and may not offset the impact of the changes in exchange rates on the translated value of sales or costs. In addition, if we increase the selling price of our products in local currencies this could have a negative impact on the demand for our products.
Major customers. While we have historically depended on a few customers for a large percentage of our annual net sales, the composition of this group can change from year to year. Net sales derived from our five largest customers as a percentage of our net sales was 21% for the six months ended June 30, 2016 and 25%, 23% and 21% for the full years 2015, 2014 and 2013, respectively. None of our customers accounted for more than 10% of our net sales for the six months ended June 30, 2016. Our largest customer accounted for 13% of our net sales for the six months ended June 30, 2015. We seek to add new customers and to expand our relationships with existing customers. We anticipate that the composition of our significant customers will continue to change. If any of our significant customers substantially reduced their purchases from us, our results would be adversely affected.
Results of Operations for the three months ended June 30, 2016 compared to the three months ended June 30, 2015
Net sales. Net sales increased by $17.7 million, or 7.5%, to $252.8 million for the three months ended June 30, 2016 from $235.1 million for the three months ended June 30, 2015.

Sales for materials processing applications increased due to an increase in sales of high-power lasers, medium-power lasers, pulsed lasers, QCW lasers and laser systems.
High-power laser sales increased due to higher demand for cutting, cladding, laser sintering and heat treatment and annealing applications. High-power lasers are continuing to displace CO2 lasers in cutting systems sold by our OEM customers. We are also seeing increased use of high-power lasers for deposition applications like cladding and laser sintering which is used in additive manufacturing. Our additive manufacturing OEM customers are producing systems using lasers with higher output powers in order to improve the speed with which parts are grown. The increase in heat treatment and annealing applications was due to a large order from one customer. These increases were offset by decreases in average selling prices for high-power lasers.
Medium-power laser sales increased due to higher sales for fine cutting and laser sintering applications. Medium power lasers are increasingly being used for fine material processing such as cutting thin metals in the consumer electronics industry as well as laser sintering in the 3D manufacturing industry. These increases were offset by decreases in average selling prices for medium-power lasers.
Pulsed laser sales increased due to higher demand for marking and engraving, ablation and cleaning applications. Marking and engraving applications are increasing due to increased demand in consumer electronics and packaging. Our high power pulsed lasers are being adopted for ablation and cleaning applications such as cleaning molds in addition to marking and engraving applications.
QCW laser sales increased due to higher demand for fine welding applications. QCW lasers are continuing to gain acceptance and displace YAG lasers in fine processing systems sold by our OEM customers.
The increase in laser system sales contributed to the increase in other revenue detailed above. Increased sales in laser systems are due to increased demand for customized laser system solutions as a result of the investments we have made to develop laser systems for various applications and in the sales and distribution network to support this product line.
Sales for other applications increased due to higher sales for advanced applications and telecom applications. The increase in sales for advanced applications was driven by government and aerospace applications and contributed to increased high-power laser sales and sales of certain components included in other revenue detailed above. The increase in telecom sales was driven by a $2.3 million of sales from the Menara acquisition and also an increase in amplifier sales used for last mile fiber access to the home applications that also contributed to the increase in other revenue detailed above. These sales increases were partially offset by a decrease in medical application sales which is the primary reason for the decrease in low-power lasers detailed above.
Cost of sales and gross margin. Cost of sales increased by $8.6 million, or 8.1%, to $115.1 million for the three months ended June 30, 2016 from $106.4 million for the three months ended June 30, 2015. Our gross margin decreased to 54.5% for the three months ended June 30, 2016 from 54.7% for the three months ended June 30, 2015. Gross margin decreased due to decrease in absorption of manufacturing costs in the quarter and increased provision for inventory reserves. These impacts were partially mitigated by decreases in the cost of internally manufactured components and increased manufacturing efficiency

15


which have offset decreases in average selling prices. Gross margin also benefited from product mix including increased sales of high-power lasers with higher output powers, medium-power lasers and high-power pulsed lasers.
Sales and marketing expense. Sales and marketing expense increased by $1.7 million, or 3.8%, to $9.7 million for the three months ended June 30, 2016 from $8.0 million for the three months ended June 30, 2015, primarily as a result of an increase in personnel, trade fairs and exhibitions, depreciation and premises costs. As a percentage of sales, sales and marketing expense increased to 3.8% for the three months ended June 30, 2016 from 3.4% for three months ended June 30, 2015.
Research and development expense. Research and development expense increased by $3.3 million, or 21.8%, to $18.4 million for the three months ended June 30, 2016, compared to $15.1 million for the three months ended June 30, 2015, primarily as a result of an increase in personnel expense, stock-based compensation, cost of materials used for research and development projects and depreciation expense. These increased costs were partially offset by a decrease in the cost of outside contractors. Research and development continues to focus on developing new products including lasers at different wavelengths such as UV, green and mid-infrared lasers, new pulsed laser products such as high-power pulsed products and ultra-fast pulsed products, new laser based systems such as material processing systems, projection and display devices and medical devices and new accessories such as welding and cutting heads. In addition to new products R&D is focused on enhancing the performance of our internally manufactured components, refining production processes to improve manufacturing yields and achieving better electrical efficiency and higher output powers. As a percentage of sales, research and development expense increased to 7.3% for the three months ended June 30, 2016 from 6.4% for the three months ended June 30, 2015.
General and administrative expense. General and administrative expense increased by $1.1 million, or 7.6%, to $16.2 million for the three months ended June 30, 2016 from $15.0 million for the three months ended June 30, 2015. This was primarily as a result of increased stock-based compensation and legal, consulting and information technology costs partially offset by decreases in bad debt provision. As a percentage of sales, general and administrative expense was 6.4% for the three months ended June 30, 2016 and for the three months ended June 30, 2015.
Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates relative to the U.S. Dollar had been the same as one year ago, which were on average Euro 0.90, Russian Ruble 53, Japanese Yen 121 and Chinese Yuan 6.12, respectively, we would have expected net sales to be $3.2 million higher, gross profit to be $1.1 million higher and total operating expenses would have been $1.0 million higher.
(Gain) loss on foreign exchange. We incurred a foreign exchange gain of $1.6 million for the three months ended June 30, 2016 as compared to $3.2 million loss for the three months ended June 30, 2015. Foreign exchange gains for the three months ended June 30, 2016 were primarily attributable to the appreciation of the U.S. Dollar compared to the Euro and the appreciation of the Japanese Yen compared to the U.S. Dollar partially offset by the appreciation of the U.S. Dollar compared to the Russian Ruble and Chinese Yuan. Foreign exchange losses for the three months ended June 30, 2015 were primarily attributable to the appreciation of the Euro compared to the US Dollar.
Interest income (expense), net. Interest income (expense), increased to $0.3 million of income for the three months ended June 30, 2016 from $0.1 million of expense for the three months ended June 30, 2015 as a result of higher yielding interest on investments.
Other income, net. Other income, remained relatively flat for the three months ended June 30, 2016 and 2015.
Provision for income taxes. Provision for income taxes was $28.4 million for the three months ended June 30, 2016 compared to $26.2 million for the three months ended June 30, 2015. The effective tax rates were 29.8% and 30.0% for the three months ended June 30, 2016 and 2015, respectively. The decrease in the effective rate was primarily due to the mix of income earned in various tax jurisdictions and research and development tax credits. The legislation enabling research and development credits in the United States was permanently enacted at the end of 2015. As it was not permanently re-enacted until the end of the year, there was no benefit related to research and development credits for the three months ended June 30, 2015.
Net income attributable to IPG Photonics Corporation. Net income attributable to IPG Photonics Corporation increased by $5.8 million to $67.1 million for the three months ended June 30, 2016 compared to $61.3 million for the three months ended June 30, 2015. Net income attributable to IPG Photonics Corporation as a percentage of our net sales increased by 0.4 percentage points to 26.5% for the three months ended June 30, 2016 from 26.1% for the three months ended June 30, 2015 due to the factors described above.
Results of Operations for the six months ended June 30, 2016 compared to the six months ended June 30, 2015

Sales for materials processing applications increased due to higher sales of high-power lasers, medium-power lasers, pulsed lasers, QCW lasers and laser systems.
High-power laser sales increased due to higher demand for cutting, cladding, laser sintering and heating and annealing applications partially offset by a decline in automotive related welding applications and decreases in average selling prices. High-power lasers are continuing to displace CO2 lasers in cutting systems sold by our OEM customers. We are also seeing increased use of high-power lasers for deposition applications like cladding and laser sintering which is used in additive manufacturing. Our additive manufacturing OEM customers are producing systems using lasers with higher output powers in order to improve the speed with which parts are grown.

These increases were offset by decreases in average selling prices for medium-power lasers.
Pulsed laser sales increased due to higher demand for marking and engraving applications. Marking and engraving applications are increasing due to increased demand in consumer electronics and packaging and due to increased performance offered by our high-power pulsed products.
QCW lasers increased due to higher demand in metal welding applications. QCW lasers are continuing gain acceptance and displace YAG lasers in fine processing systems sold by our OEM customers.
The increase in laser system sales contributed to the increase in other revenue detailed above. Increased sales in laser systems are due to increased demand for customized laser system solutions as a result of the investments we have made to develop laser systems for various applications and in the sales and distribution network to support this product line.
Sales for other applications increased due to higher sales for advanced applications and telecom applications. The increase in sales for advanced applications was driven by government and aerospace applications and contributed to increased high-power laser sales and sales of certain components included in other revenue detailed above. The increase in telecom sales was driven by a $2.3 million impact from the Menara acquisition and also an increase in amplifier sales used for last mile fiber access to the home applications that also contributed to the increase in other revenue detailed above. These sales increases were

17


partially offset by a decrease in medical application sales which is also the primary reason for the decrease in low-power lasers detailed above.
Cost of sales and gross margin. Cost of sales increased by $10.3 million, or 5.2%, to $207.9 million for the six months ended June 30, 2016 from $197.6 million for the six months ended June 30, 2015. Our gross margin increased to 54.8% from 54.5% for the six months ended June 30, 2016 and 2015, respectively. Gross margin increased due to decreases in the cost of internally manufactured components and increased manufacturing efficiency which have offset decreases in average selling prices. Gross margin also benefited from product mix including increased sales of high-power lasers with higher output powers, medium-power lasers and high-power pulsed lasers. These benefits were partially offset by a decrease in absorption of manufacturing costs in the period and increased provision for inventory reserves.
Sales and marketing expense. Sales and marketing expense increased by $2.2 million, or 14.3%, to $17.7 million for the six months ended June 30, 2016 from $15.5 million for the six months ended June 30, 2015, primarily as a result of increases in personnel, stock-based compensation, trade show and exhibitions cost and premises cost As a percentage of sales, sales and marketing expense increased to 3.9% for the six months ended June 30, 2016 from 3.6% for the six months ended June 30, 2015.
Research and development expense. Research and development expense increased by $6.6 million, or 22.3%, to $35.9 million for the six months ended June 30, 2016, compared to $29.3 million for the six months ended June 30, 2015, primarily as a result of an increase in personnel, stock-based compensation, premises, depreciation and materials used for research and development. These increases were partially offset by decreased expenses related to outside research and development contracts. Research and development continues to focus on developing new products including lasers at different wavelengths such as UV, green and mid-infrared lasers, new pulsed laser products such as high-power pulsed products and ultra-fast pulsed products, new laser based systems such as material processing systems, projection and display devices and medical devices and new accessories such as welding and cutting heads. In addition to new products R&D is focused on enhancing the performance of our internally manufactured components, refining production processes to improve manufacturing yields and achieving better electrical efficiency and higher output powers. As a percentage of sales, research and development expense increased to 7.8% for the six months ended June 30, 2016 from 6.8% for the six months ended June 30, 2015.
General and administrative expense. General and administrative expense increased by $2.3 million, or 8.1%, to $30.1 million for the six months ended June 30, 2016 from $27.8 million for the six months ended June 30, 2015, primarily as a result of increased personnel, stock-based compensation and legal and consulting costs. As a percentage of sales, general and administrative expense increased to 6.5% for the six months ended June 30, 2016 from 6.4% for the six months ended June 30, 2015.
Effect of exchange rates on net sales, gross profit and operating expenses. We estimate that, if exchange rates relative to the U.S. Dollar had been the same as one year ago, which were on average Euro 0.90, Russian Ruble 58, Japanese Yen 120 and Chinese Yuan 6.14, respectively, we would have expected net sales for the six months ended June 30, 2016 to be $8.6 million higher, gross profit to be $3.9 million higher and total operating expenses would have been $2.0 million higher.
(Gain) loss on foreign exchange. We incurred a foreign exchange loss of $3.4 million for the six months ended June 30, 2016 as compared to a $5.6 million gain for the six months ended June 30, 2015. The loss for the six months ended June 30, 2016 was primarily attributable to the appreciation of the Euro compared to the U.S. Dollar partially offset by the appreciation of the U.S. Dollar compared to the Russian Ruble and Chinese Yuan. The gain for the six months ended June 30, 2015 was primarily attributable to the appreciation of the U.S. Dollar compared to the Euro.
Interest income (expense), net. Interest income (expense), increased to $0.5 million of income for the six months ended June 30, 2016 from $0.3 million of expense for the six months ended June 30, 2015 as a result of higher yielding interest on investments.
Other income, net. Other income, net decreased to $0.1 million of income for the six months ended June 30, 2016 compared to approximately $0.2 million of income for the six months ended June 30, 2015.
Provision for income taxes. Provision for income taxes was $49.3 million for the six months ended June 30, 2016 compared to $50.8 million for the six months ended June 30, 2015, representing an effective tax rate of 29.8% and 30.0% for the six months ended June 30, 2016 and 2015, respectively. The decrease in the effective rate was primarily due to the mix of income earned in various tax jurisdictions and research and development tax credits. The legislation enabling research and development credits in the United States was permanently enacted at the end of 2015. As it was not permanently re-enacted until the end of the year, there was no benefit related to research and development credits for the six months ended June 30, 2015.

Net income attributable to IPG Photonics Corporation. Net income attributable to IPG Photonics Corporation decreased by $2.3 million to $116.4 million, or 1.9% for the six months ended June 30, 2016 compared to $118.7 million for the six months ended June 30, 2015. Net income attributable to IPG Photonics Corporation as a percentage of our net sales decreased by 2.0 percentage points to 25.3% for the six months ended June 30, 2016 from 27.3% for the six months ended June 30, 2015 due to the factors described above.
Liquidity and Capital Resources
Our principal sources of liquidity as of June 30, 2016 consisted of cash and cash equivalents of $587.3 million, short-term investments of $126.8 million, unused credit lines and overdraft facilities of $77.5 million and other working capital (excluding cash and cash equivalents and short-term investments) of $348.2 million. This compares to cash and cash equivalents of $582.5 million, short-term investments of $106.6 million, unused credit lines and overdraft facilities of $73.9 million and other working capital (excluding cash and cash equivalents and short-term investments) of $288.8 million as of December 31, 2015. The increase in cash and cash equivalents of $4.8 million relates primarily to cash provided by operating activities in the six months ended June 30, 2016 of $105.3 million, cash provided by financing activities of $33.4 million and effect of exchange rates on cash of $3.7 million which was partially offset by cash used in investing activities of $137.6 million which related to capital expenditures, acquisition of Menara Networks and increases in short-term investments.
Short-term investments consist of liquid investments including U.S. government and government agency notes, corporate
notes, commercial paper and certificates of deposit with original maturities of greater than three months but less than one year.
Our long-term debt consists of two long-term notes totaling $42.4 million of which $3.2 million is the current portion. During the second quarter of 2016, we financed the purchase of a building in Marlborough, Massachusetts with an unsecured note of $23.8 million. The interest on this unsecured long-term note is variable at 1.20% above the LIBOR rate and is fixed using an interest rate swap at 2.85% per annum. The unsecured long-term note matures in May 2023, at which time the outstanding debt balance will be $15.4 million. The amount due on this unsecured long-term note as of June 30, 2016 was $23.8 million of which $1.2 million is the current portion. The Company has another note that is secured by the Company's corporate aircraft. The interest rate on this collateralized long-term note is fixed at 2.81% per annum and the collateralized long-term note matures in October 2019, at which time the outstanding debt balance will be $12.0 million. The amount due on this collateralized long-term note at June 30, 2016 was $18.7 million of which $2.0 million is the current portion.
We believe that our existing cash and marketable securities, our cash flows from operations and our existing lines of credit provides us with the financial flexibility to meet our liquidity and capital needs and to complete potential acquisitions of businesses and technologies. Our future long-term capital requirements will depend on many factors including our level of sales, the impact of economic environment on our sales levels, the timing and extent of spending to support development efforts, the expansion of the global sales and marketing activities, government regulation including trade sanctions, the timing and introductions of new products, the need to ensure access to adequate manufacturing capacity and the continuing market acceptance of our products.

Our largest committed credit lines are with Bank of America N.A. and Deutsche Bank AG in the amounts of $50.0 million and $33.3 million (or 30 million Euro as described above), respectively, and neither of them is syndicated.
We are required to meet certain financial covenants associated with our U.S. revolving line of credit and long-term debt facility. These covenants, tested quarterly, include a debt service coverage ratio and a funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA") ratio. The debt service coverage covenant requires that we maintain a trailing twelve month ratio of cash flow to debt service that is at least 1.5:1. Debt service is defined as required principal and interest payments during the period. Debt service in the calculation is decreased by our cash held in the U.S.A. in excess of $50 million up to a maximum of $250 million. Cash flow is defined as EBITDA less unfunded capital expenditures. The funded debt to EBITDA covenant requires that the sum of all indebtedness for borrowed money on a consolidated basis be less than three times our trailing twelve months EBITDA. We were in compliance with all such financial covenants as of and for the three months ended June 30, 2016.
Operating activities. Net cash provided by operating activities increased by $3.9 million to $105.3 million for the six months ended June 30, 2016 from $101.4 million for the six months ended June 30, 2015. Net cash provided by operating activities is generally driven by cash provided by net income after adding back non-cash charges offset by continued growth in working capital to support the growth of the business. Our largest working capital items are inventory and accounts receivable. Items such as accounts payable to third parties, prepaid expenses and other current assets and accrued expenses and other liabilities are not as significant as our working capital investment in accounts receivable and inventory. The relatively high level of investment in inventory is primarily attributable to the amount of value added internally which is primarily due to our vertically integrated structure. Accruals and payables for personnel costs including bonuses and income and other taxes payable are largely dependent on the timing of payments for those items. Increases in cash flow from operating activities for the six months ended June 30, 2016 primarily resulted from:
An increase in cash provided by net income after adding back non-cash charges of $3.2 million to $164.2 million in the six months ended June 30, 2016 as compared to $161.0 million in the same period in 2015 mainly resulting from an increase in depreciation and amortization and stock-based compensation which was partially offset by a decrease in net income and changes in deferred income taxes between the two periods;
A decrease in accounts receivable of $2.9 million in the six months ended June 30, 2016 as compared to an increase of $31.7 million in the same period in 2015; partially offset by
An increase in inventory of $34.7 million in the six months ended June 30, 2016 as compared to an increase of $33.2 million in the same period in 2015.
Given our vertical integration, rigorous and time-consuming testing procedures for both internally manufactured and externally purchased components and the lead time required to manufacture components used in our finished products, the rate at which we turn inventory has historically been comparatively low when compared to our cost of sales. Also, our historic growth rates required investment in inventories to support future sales and enable us to quote short delivery times to our customers, providing what we believe is a competitive advantage. Furthermore, if there was a disruption to the manufacturing capacity of any of our key technologies, our inventories of components should enable us to continue to build finished products for a reasonable period of time. We believe that we will continue to maintain a relatively high level of inventory compared to our cost of sales. As a result, we expect to have a significant amount of working capital invested in inventory. A reduction in our level of net sales or the rate of growth of our net sales from their current levels would mean that the rate at which we are able to convert our inventory into cash would decrease.
Investing activities. Net cash used in investing activities was $137.6 million and $37.3 million in the six months ended June 30, 2016 and 2015, respectively. The cash used in investing activities in 2016 related to $70.9 million for the construction of new buildings in the United States, Germany and Russia, purchases of machinery and equipment and the purchase of a building in Marlborough, MA. Additionally, cash used for investing activities in the six months ended June 30, 2016 included $46.5 million for the purchase of Menara Networks, net of cash acquired and $20.5 million of net purchases of short-term investments. The cash used in investing activities in 2015 related to $32.6 million for the construction and purchase of new buildings in the United States, Germany and Russia, purchases of machinery and equipment and $5.0 million for the the purchase of a majority interest in a company. 
We expect to incur between $100 million and $110 million in capital expenditures, excluding acquisitions, in 2016, as we continue to upgrade facilities and equipment to add capacity worldwide to support anticipated revenue growth. The timing and extent of any capital expenditures in and between periods can have a significant effect on our cash flow. Many of the capital expenditure projects that we undertake have long lead times and are difficult to cancel or defer to a later period.

Financing activities. Net cash provided by financing activities was $33.4 million and $2.1 million in the six months ended June 30, 2016 and 2015, respectively. The cash provided by financing activities in 2016 was primarily related to proceeds of $23.8 million from financing related to the purchase of a building in Marlborough, MA, as well as cash provided by the exercise of stock options, sales of shares under our employee stock purchase plan and the related tax benefits of the exercises partially offset by the payments on our long-term borrowings and net payments of line-of-credit facilities. The cash provided by financing activities in 2015 was primarily related to the cash provided by the exercise of stock options, sales of shares under our employee stock purchase plan and the related tax benefits of the exercises partially offset by the payments on our long-term borrowings and net payments of line-of-credit facilities.

Recent Accounting Pronouncements
In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" ("ASU 2016-09"). The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. The impact that the standard will have on our consolidated financial statements will depend upon certain criteria including the timing of the exercise and release of equity instruments, the value realized upon exercise or release of equity instruments and the fair value of the equity instruments when they were granted. The excess tax benefit from the exercise of equity instruments was $3.0 million and $5.7 million for the six months ended June 30, 2016 and 2015, respectively.
In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"). The standard requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the impact that the standard will have and do not expect it to have a material impact on our consolidated financial statements upon adoption.
In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" ("ASU 2016-01"). The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. We are currently evaluating the impact that the standard will have and do not expect it to have a material impact on our consolidated financial statements upon adoption.
In November 2015, the FASB issued amended guidance that clarifies that in a classified statement of financial position, an entity shall classify deferred tax liabilities and assets as non-current amounts. The new guidance supersedes ASC 740-10-45-5 which required the deferred tax assets and liabilities for a particular tax jurisdiction be allocated between current and non-current deferred tax assets for that tax jurisdiction on a pro rata basis. The new standard will become effective for our

21


fiscal year beginning January 1, 2017. We have determined that the standard will not have a material impact on our consolidated financial statements upon adoption. Current deferred tax assets at June 30, 2016 and December 31, 2015 were $24.5 million and $20.3 million, respectively. Current deferred tax liabilities at June 30, 2016 and December 31, 2015 were $4.2 million and $3.2 million, respectively.
In May 2014, the FASB issued Accounting Standards Update No. 2014-09 ("ASU 2014-09") "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)", and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the
consideration to which the entity expects to be entitled to in exchange for those goods or services. As currently issued and
amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods
within that reporting period, though early adoption is permitted for annual reporting periods beginning after December 15, 2016. We are currently in the process of evaluating the impact of the adoption of ASU 2014-09 on our consolidated financial statements and do not expect it to have a material impact on our consolidated financial statements upon adoption.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risk in the ordinary course of business, which consists primarily of interest rate risk associated with our cash and cash equivalents and our debt and foreign exchange rate risk.
Interest rate risk. Our investments have limited exposure to market risk. We maintain a portfolio of cash, cash equivalents and short-term investments, consisting primarily of bank deposits, money market funds, certificates of deposit, corporate notes and government and agency securities. None of these investments have a maturity date in excess of one year. The interest rates are variable and fluctuate with current market conditions. Because of the short-term nature of these instruments, a sudden change in market interest rates would not be expected to have a material impact on our financial condition or results of operations.
We are also exposed to market risk as a result of increases or decreases in the amount of interest expense we must pay on our bank debt and borrowings on our bank credit facilities. Our interest obligations on our long-term debt are fixed either by the underlying agreement or by means of an interest rate swap agreement. Although our U.S. revolving line of credit and our Euro credit facility have variable rates, we do not believe that a 10% change in market interest rates would have a material impact on our financial position or results of operations.
Exchange rates. Due to our international operations, a significant portion of our net sales, cost of sales and operating expenses are denominated in currencies other than the U.S. Dollar, principally the Euro, the Russian Ruble, the Chinese Yuan and the Japanese Yen. As a result, our international operations give rise to transactional market risk associated with exchange rate movements of the U.S. Dollar, the Euro, the Russian Ruble, the Chinese Yuan and the Japanese Yen. Gain on foreign exchange transactions totaled $1.6 million for the three months ended June 30, 2016 and a loss of $3.2 million for the three months ended June 30, 2015. Management attempts to minimize these exposures by partially or fully off-setting foreign currency denominated assets and liabilities at our subsidiaries that operate in different functional currencies. The effectiveness of this strategy can be limited by the volume of underlying transactions at various subsidiaries and by our ability to accelerate or delay inter-company cash settlements. As a result, we are unable to create a perfect offset of the foreign currency denominated assets and liabilities. Furthermore, if we expect a currency movement to be beneficial to us in the short or medium term, we have, on occasions, chosen not to hedge or otherwise off-set the underlying assets or liabilities. However, it is difficult to predict foreign currency movements accurately. At June 30, 2016, our material foreign currency exposure is net U.S. Dollar denominated assets at subsidiaries where the Euro or the Russian Ruble is the functional currency and U.S. Dollar denominated liabilities where the Chinese Yuan is the functional currency. The net U.S. Dollar denominated assets are comprised of cash, third party receivables, inter-company receivables and inter-company notes offset by third party and inter-company U.S. Dollar denominated payables. The U.S. Dollar denominated liabilities are comprised of inter-company payables. A 5% change in the relative exchange rate of the U.S. Dollar to the Euro as of June 30, 2016 applied to the net U.S. Dollar asset balances, would result in a foreign exchange gain of $8.7 million if the U.S. Dollar appreciated and a $8.7 million foreign exchange loss if the U.S. Dollar depreciated.
In addition we are exposed to foreign currency translation risk for those subsidiaries whose functional currency is not the U.S. Dollar as changes in the value of their functional currency relative to the U.S. Dollar can adversely affect the translated amounts of our revenue, expenses, net income, assets and liabilities. This can, in turn, affect the reported value and relative growth of sales and net income from one period to the next. In addition changes in the translated value of assets and liabilities due to changes in functional currency exchange rates relative to the U.S. Dollar result in  foreign currency translation adjustments that are a component of other comprehensive income or loss.
Foreign currency derivative instruments can also be used to hedge exposures and reduce the risks of certain foreign currency transactions; however, these instruments provide only limited protection and can carry significant cost. We have no

22


foreign currency derivative instrument hedges as of June 30, 2016. We will continue to analyze our exposure to currency exchange rate fluctuations and may engage in financial hedging techniques in the future to attempt to minimize the effect of these potential fluctuations. Exchange rate fluctuations may adversely affect our financial results in the future.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Under the supervision of our chief executive officer and our chief financial officer, our management has evaluated the effectiveness of the design and operation of our "disclosure controls and procedures" (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as of the end of the period covered by this Quarterly Report on Form 10-Q (the "Evaluation Date"). Based upon that evaluation, our chief executive officer and our chief financial officer have concluded that, as of the Evaluation Date, our disclosure controls and procedures are effective.
Changes in Internal Controls
There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
From time to time, we are party to various legal proceedings and other disputes incidental to our business. There have been no material developments to those proceedings reported in our Annual Report on Form 10-K for the year ended December 31, 2015, except that we have settled the lawsuit filed against us in November 2015 in the United States District Court for the Eastern District of Texas for alleged patent infringement.
ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, "Item 1A.

The risks described in our Annual Report on Form 10-K and Quarterly Reports on Form 10-Q are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
