(1) A full reconciliation of CBOE Holdings’ non-GAAP results to its GAAP results for the reporting periods is included in the attached tables. See “Non-GAAP Information” in the accompanying financial tables.

For the year ended December 31, 2011, CBOE Holdings reported record revenues and earnings.  GAAP net income allocated to common stockholders increased 40 percent to $137.1 million, or $1.52 per diluted share, on total operating revenues of $508.1 million.  For the comparable period in 2010, the company reported GAAP net income allocated to common stockholders of $98.2 million, or $1.03 per diluted share, on operating revenues of $437.1 million.  On an adjusted basis, net income allocated to common stockholders increased 38 percent to $143.7 million from $104.2 million in 2010, while adjusted diluted earnings per share grew 47 percent to $1.60 from $1.09 in 2010.

CBOE Holdings’ financial results for the three and twelve months ended December 31, 2011 and 2010 included certain items and allocations that management believes are not representative of its operating performance.  Financial measures presented on an adjusted basis exclude these items to present a more meaningful comparison.  More information on the adjusted financial measures and a detailed analysis are included in the “Non-GAAP Information.”

“2011 was a record year for CBOE Holdings as we set new highs across our key financial metrics, including revenues, earnings, trading volume and operating margin.  Thanks to the expertise and dedication of our employees, we continued to meet the needs of our customers throughout the year by offering the industry’s most diverse product line, unparalleled customer service, and trading technology that is second to none,” said William J. Brodsky, CBOE Holdings Chairman and Chief Executive Officer.  “As a result, our company is stronger than ever and well positioned for future growth and to generate increased financial returns for our stockholders.”

“Our solid fourth quarter results cap an outstanding year for CBOE Holdings as we set new records for both top-line and bottom-line financial measures for 2011.  Throughout the year we continued to demonstrate strong expense control, delivering a record adjusted operating margin of 48.4 percent for 2011,” said Alan J. Dean, CBOE Holdings Executive Vice President and Chief Financial Officer.  “Our strong cash flow enabled us to return nearly $92 million to stockholders through dividends and share repurchases, bringing the total returned to stockholders over the past 18 months to more than $525 million.  In addition, we ended the year with a strong cash position of more than $135 million, providing us with the flexibility to continue to enhance share value through both internal investments and other capital allocation opportunities,” Dean added.

The table below highlights CBOE Holdings’ operating results for the comparative quarters and twelve-month periods ended December 31, 2011 and 2010.

Key Statistics and Financial Highlights:

(1) Trading days in the fourth quarter of 2011 and 2010 totaled 63 and 64, respectively.

(2) A full reconciliation of our non-GAAP results to our GAAP results for the 2011 and 2010 reporting periods is included in the attached tables.

Revenues

Adjusted operating revenues in the fourth quarter of 2011 increased $7.2 million, or 6 percent, to $120.2 million from $113.0 million in 2010’s fourth quarter.  This increase primarily reflects a $7.2 million increase in transaction fees and a $0.7 million increase in exchange services and other fees, offset somewhat by a $1.3 million decrease in access fees.  Access fees declined primarily due to the implementation of a sliding fee scale for certain trading permits effective January 2011.  Exchange services and other fees were up primarily due to fee increases for certain user services versus the fourth quarter of 2010.

Transaction fees increased 9 percent for the quarter due to a 10 percent increase in the average transaction fee per contract, offset slightly by a 1 percent decrease in trading volume compared with the fourth quarter of 2010.  Trading volume for the fourth quarter was 270.9 million contracts, or 4.30 million contracts per day, versus 2010’s fourth quarter volume of 272.8 million contracts, or 4.26 million contracts per day.  The average transaction fee per contract increased to $0.321 compared with $0.293 in the fourth quarter of 2010.

The increase in the average transaction fee per contract resulted primarily from a shift in trading volume mix, with higher-margin index options and futures contracts accounting for 28.9 percent of total contracts traded during the quarter versus 23.8 percent in the fourth quarter of 2010.  The average transaction fee per contract represents total transaction fee revenue divided by total reported trading volume for CBOE, C2 Options Exchange (C2) and CBOE Futures Exchange (CFE).

Adjusted Operating Expenses

Adjusted operating expenses of $63.8 million for the fourth quarter of 2011 was nearly flat compared with $63.5 million in the fourth quarter of 2010.  Adjusted operating expenses for the fourth quarters of 2011 and 2010 exclude $3.7 million for severance paid pursuant to an executive employment contract and $2.0 million for accelerated stock-based compensation expense, respectively.

The company’s core operating expenses of $41.5 million for the fourth quarter of 2011 increased by $1.5 million, or 4.0 percent, compared with last year’s fourth quarter, primarily driven by increases in travel and promotional expenses and employee costs, offset somewhat by lower data processing expenses.  Travel and promotional expenses were up due to an increase in advertising to support the launch of SPXpm.  The increase in employee costs was primarily related to higher expenses for employee benefits.

Core operating expenses represent total operating expenses less volume-based expenses, depreciation and amortization, accelerated stock-based compensation expense and unusual or one-time expenses.

Volume-based expenses, which include royalty fees and trading volume incentives, were $14.8 million in the fourth quarter of 2011, a decrease of $0.6 million, or 4 percent, compared with the same period last year.  This decrease reflects a $2.6 million increase in royalty fees, which are directly related to higher trading volume in licensed index products, offset by a $3.2 million decrease in trading volume incentives.  The decline in trading volume incentives primarily resulted from changes to the program criteria.

Adjusted Operating Margin

The company’s adjusted operating margin increased 310 basis points to 46.9 percent for the fourth quarter of 2011, compared with 43.8 percent in the same period in 2010, representing the company’s sixth consecutive quarter of year-over-year operating margin increases.  The adjusted operating margin for the full-year 2011 was 48.4 percent, the highest annual level in the company’s history.

Effective Tax Rate

The GAAP effective tax rate for the fourth quarter increased to 39.2 percent from 37.2 percent in last year’s fourth quarter, primarily due to the impact of an increase in the Illinois tax rate effective January 1, 2011, offset somewhat by tax benefits recorded in the fourth quarter to recognize tax credits and the adjustment of deferred tax positions.

The adjusted effective tax rate, which excludes the benefit for tax credits related to prior years, was 39.8 percent compared with 37.2 percent for the fourth quarter of 2010.

2012 Fiscal Year Financial Guidance

CBOE Holdings currently expects the following for the year ended December 31, 2012:

·                  The company expects revenue from exchange services and other fees to be in the range of $24.0 million to $26.0 million, a projected increase of about $6.0 million to $8.0 million from $18.2 million reported in 2011. This increase primarily reflects higher fees related to connectivity charges, registration fees and co-location fees.

·                  Consolidated access fees are expected to be in a range of $64.0 million to $67.0 million, reflecting the expected net impact of access fee changes implemented on January 3, 2012.

·                  Core expenses are expected to be in the range of $173.0 million to $178.0 million. The company expects core expenses to be at the low end of the guidance range if volume in 2012 is flat to up 4 percent and at the high end of the

range if volume growth is 5 percent or higher. The projected increase in core expenses in 2012 reflects the carryover of projects deferred in 2011 and additional expenses to support revenue growth initiatives.

·                  Continuing stock-based compensation expense, included in core expenses above, is expected to be in the range of $12.2 million to $12.7 million for the full year.

·                  The consolidated effective tax rate is expected to be in the range of 41.2 percent to 41.7 percent for the year ended December 31, 2012. Significant changes in trading volume, expenses, state and local tax rates and other items, including ongoing state and federal tax audits, could materially impact this expectation.

·                  Depreciation and amortization expense is expected to be in the range of $33.0 million to $35.0 million.

·                  Capital expenditures are projected in the range of $30.0 million to $35.0 million, primarily driven by ongoing investments in systems hardware and software that enhance trading technology.
