FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve a number of risks and uncertainties. You can identify these statements by forward-looking words such as "may," "might," "should," "expect," "plan," "anticipate," "believe," "estimate," "predict," "potential" or "continue," and the negative of these terms and other comparable terminology. All statements that reflect our expectations, assumptions or projections about the future other than statements of historical fact are forward-looking statements, including statements in "Management's Discussion and Analysis of Financial Condition and Results of Operations." These forward-looking statements, which are subject to known and unknown risks, uncertainties and assumptions about us, may include projections of our future financial performance based on our growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from that expressed or implied by the forward-looking statements. In particular, you should consider the risks and uncertainties described under “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2011, Part II, Item 1A of this Quarterly Report on Form 10-Q and our other filings with the SEC.

While we believe we have identified material risks, these risks and uncertainties are not exhaustive. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Some factors that could cause actual results to differ include:

• the loss of our right to exclusively list certain premium products;

• decreases in the amount of trading volumes or a shift in the mix of products traded on our exchanges;

• compliance with legal and regulatory obligations;

• increasing competition by foreign and domestic entities, including increased competition from new entrants into our markets and consolidation of existing entities;

• increasing price competition in our industry;

• our ability to maintain access fee revenues;

• economic, political and market conditions;

• our ability to operate our business without violating the intellectual property rights of others and the costs associated with protecting our intellectual property rights;

• our ability to accommodate trading volume and order transaction traffic, including increases in trading volume and order transaction traffic, without failure or degradation of performance of our systems;

• our ability to protect our systems and communication networks from security risks, including cyber attacks;

• our ability to attract and retain skilled management and other personnel;

• our ability to maintain our growth effectively;

• our dependence on third party service providers; and

• the ability of our compliance and risk management methods to effectively monitor and manage our risks.

For a detailed discussion of these and other factors that might affect our performance, see Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2011, Part II, Item 1A of this Quarterly Report on Form 10-Q and our other filings with the SEC. We caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this filing.

CBOE HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the three and nine months ended September 30, 2012 and 2011

(unaudited)

NOTE 1 —DESCRIPTION OF BUSINESS

CBOE Holdings is the holding company of registered securities exchanges, subject to oversight by the SEC, and of a designated contract market subject to the oversight of the CFTC.

The primary business of the Company is the operation of markets for the trading of listed options contracts on three broad product categories: 1) the stocks of individual corporations (equity options), 2) various market indexes (index options) and 3) other exchange-traded products such as exchange-traded funds (ETF options) and exchange-traded notes (ETN options). We also offer futures through a futures market. The Company owns and operates three stand-alone exchanges, but reports the results of its operations in one reporting segment. CBOE is our largest exchange by volume and offers trading for listed options through a single system that integrates electronic trading and traditional open outcry trading on our trading floor in Chicago. This integration of electronic trading and traditional open outcry trading into a single market is known as our Hybrid trading model. C2, our all-electronic exchange, also offers trading for listed options, but with a different market model and fee schedule than CBOE. Finally, CFE, our all-electronic futures exchange, offers futures on the CBOE Volatility Index (the VIX Index), as well as on other products. All of our exchanges operate on our proprietary technology platform known as CBOECommand.

In September 2012, the Company announced plans to establish a CFE technology hub in London which will provide European firms a cost-efficient way to send and receive CFE data and to execute trades.

NOTE 2 — BASIS OF PRESENTATION

These interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of operating revenues and expenses. On an ongoing basis, the Company evaluates its estimates, including those related to matters that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. These estimates are based on management’s knowledge and judgments, historical experience and observance of trends in particular matters. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented have been included. The results of operations for interim periods are not necessarily indicative of the results of operations for the full year.

NOTE 3 — SHARE REPURCHASE PROGRAM

On August 2, 2011, the Company announced that its board of directors had approved a share repurchase program that authorizes the Company to purchase up to $100 million of its unrestricted common stock. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

On July 31, 2012, the Company announced that its board of directors had approved the repurchase of an additional $100 million of its outstanding unrestricted common stock. This program is in addition to any amount remaining under the August 2011 authorization.

From August 2011 through September 30, 2012, the Company purchased 3,707,424 shares of unrestricted common stock at an average cost per share of $26.09 totaling $96.7 million in purchases under the program.

10

For the nine months ended September 30,2012, the Company purchased 1,871,424 shares of unrestricted common stock at an average cost per share of $26.58 totaling $49.7 million in purchases under the program. The Company did not repurchase any shares in the three months endedSeptember 30, 2012.

NOTE 4 — NET INCOME PER COMMON SHARE

The unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and are included in the computation of net income per common share pursuant to the two-class method. Our restricted stock awards granted to officers, directors and employees qualify as participating securities.

The Company computes net income per common share using the two-class method, which is an allocation formula that determines the net income for common shares and participating securities. Under the authoritative guidance, the presentation of basic and diluted earnings per share is required for each class of common stock and not for participating securities. As such, the Company presents basic and diluted net income per share for its one class of common stock.

 The computation of basic net income allocated to common stockholders is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to the participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine basic net income per common share.

The dilutive effect of participating securities is calculated using the more dilutive of the treasury stock or the two-class method. Diluted net income per common share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

The following table reconciles net income allocated to common stockholders and the number of shares used to calculate the basic and diluted net income per common share for the three and nine months ended September 30, 2012 and 2011:

NOTE 5 — STOCK-BASED COMPENSATION

Stock-based compensation is based on the fair value of the award on the date of grant, which is recognized over the related service period, net of estimated forfeitures. The service period is the period over which the related service is performed, which is generally the same as the vesting period.

11

On June 14, 2012, the Company granted 38,990 shares of restricted stock to non-employee members of the board of directors at a fair value of $27.33 per share, the closing price of the Company's stock on the grant date. The shares have a one year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. On August 15, 2012, the Company granted 8,163 shares of restricted stock to certain employees at a fair value of $28.98 per share, the closing price of the Company's stock on the grant date. The shares have a three year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. Unvested portions of the restricted stock will be forfeited if the member leaves the board or the employee leaves the company prior to the applicable vesting date, except in limited circumstances.

For the three and nine months ended September 30, 2012 and 2011, the Company recognized $3.1 million and $3.0 million and $9.0 million and $9.6 million of stock-based compensation expense, respectively. The nine months ended September 30, 2012 and 2011 includes accelerated stock-based compensation expense of $0.2 million and $0.5 million, respectively, resulting from departures from the board of directors. Stock-based compensation expense is included in employee costs in the condensed consolidated statements of income.

As of September 30, 2012, the Company had unrecognized stock-based compensation of $20.6 million.  The remaining unrecognized stock-based compensation is expected to be recognized over a weighted average period of 20.2 months. The Company is projecting a forfeiture rate of 5%.

The activity in the Company’s restricted stock for the nine months ended September 30,2012 was as follows:

	Number of Shares of Restricted Stock		Weighted Average Grant-Date Fair Value
Unvested restricted stock at January 1, 2012	1,252,239		$	29.00

As of September 30, 2012 and December 31, 2011, amounts assessed by the Company on behalf of others included in current assets totaled $8.5 million and $5.2 million, respectively, and payments due to others included in current liabilities totaled $9.0 million and $5.8 million, respectively.

NOTE 9 — DEFERRED REVENUE

The following table summarizes the activity in deferred revenue for the nine months ended September 30, 2012 (in thousands):

	Balance atDecember 31,2011		CashAdditions		RevenueRecognition			Balance atSeptember 30, 2012

Total deferred revenue	$	351	$	33,120	$	(24,758	)	$	8,713

(1)  Liquidity providers who prepay transaction fees, at a minimum, for the first two levels of the liquidity provider sliding scale are eligible to participate in reduced fees assessed to contract volume above 800,000 per month. The prepayment of 2012 transaction fees totaled $29.8 million. This amount is amortized and recorded as transaction fees over the respective period.

NOTE 10 — EMPLOYEE BENEFITS

Employees are eligible to participate in the Chicago Board Options Exchange SMART Plan (“SMART Plan”). The SMART Plan is a defined contribution plan, which is qualified under Internal Revenue Code Section 401(k). The Company contributed $3.2 million and $2.7 million to the SMART Plan for the nine months ended September 30,2012 and 2011, respectively.

Eligible employees may participate in the Supplemental Employee Retirement Plan (“SERP”), Executive Retirement Plan (“ERP”) and Deferred Compensation Plan. The SERP, ERP and Deferred Compensation Plan are defined contribution plans that are nonqualified by Internal Revenue Code regulations. The Company contributed $1.0 million to the above plans for the nine months ended September 30,2012 and 2011.

The Company has a postretirement medical plan for certain current and former members of senior management. The Company recorded immaterial postretirement benefits expense for the three and nine months ended September 30,2012 and 2011.

NOTE 11 — INCOME TAXES

For the three and nine months ended September 30, 2012 and 2011, the Company recorded income tax provisions of $14.7 million and $33.2 million and $65.5 million and $80.1 million, respectively. The effective tax rate for the nine months ended September 30,2012 and 2011 was 35.8% and 42.7%, respectively. The decrease in effective tax rate for the nine months ended September 30,2012 compared to the prior year period is the result of the recognition of discrete items and the benefit of a new tax apportionment method enacted by Illinois. During the three months ended September 30, 2012 , the Company filed an amended return for 2008 and completed it return for 2011 and recognized, as a discrete item, a $7.7 million benefit for a Section 199 deduction for U.S. production activities which encompasses all personal property including computer software. The Company expects to file amended tax returns for tax years 2009 and 2010 in the fourth quarter of 2012.

The prior year effective tax rate included the impact of an increase in the Illinois tax rate effective January 1, 2011 and a charge of $4.2 million taken to increase state-related uncertain tax positions.

As of September 30, 2012 and December 31, 2011, the Company had $17.0 million and $11.4 million, respectively, of uncertain tax positions excluding interest and penalties, which, if recognized in the future, would affect the annual effective income tax rate. Reductions to uncertain tax positions primarily from the lapse of the applicable statutes of limitations during the next twelve months are estimated to be approximately $3.6 million, not including any potential new additions.

Estimated interest costs and penalties, which are classified as part of the provision for income taxes in the Company’s condensed consolidated statements of income, were $0.2 million and $(0.2) million for the three months ended September 30, 2012 and 2011. For the nine months ended September 30, 2012 the total was $0.5 million. The amount for the nine months ended September 30, 2011 is immaterial. Accrued interest and penalties were $1.2 million and $0.8 million as of September 30, 2012 and December 31, 2011.

The Company is subject to U.S. federal tax, Illinois, New Jersey and New York state taxes and Washington D.C. taxes, as well as other local jurisdictions. The Company has open tax years from 2007 on for New York, 2008 on for federal and Illinois, and 2009 on for New Jersey and Washington, D.C. The Company's tax returns have been examined by the Internal Revenue Service through 2009 and the Illinois Department of Revenue through 2008. Specific line items for the 2008 tax year are being examined by the Internal Revenue Service and the Illinois Department of Revenue. The Company is currently under audit by the Internal Revenue Service for 2010, the State of New York for the 2007 through 2009 tax years and the State of Illinois for the 2009 and 2010 tax years.

NOTE 12 — FAIR VALUE MEASUREMENTS

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk.

The Company applied FASB ASC 820, Fair Value Measurement and Disclosure (formerly, FASB Statement No. 157, Fair Value Measurements), which provides guidance for using fair value to measure assets and liabilities by defining fair value and establishing the framework for measuring fair value. ASC 820 applies to financial and nonfinancial instruments that are measured and reported on a fair value basis. The three-level hierarchy of fair value measurements is based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair-value hierarchy requires the use of observable market data when available and consists of the following levels:

• Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities.

• Level 2—Observable inputs, either direct or indirect, not including Level 1, corroborated by market data or based upon quoted prices in non-active markets.

• Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability.

14

The Company has included a tabular disclosure for financial assets that are measured at fair value on a recurring basis in the condensed consolidated balance sheet as of September 30, 2012 and December 31, 2011. The Company holds no financial liabilities that are measured at fair value on a recurring basis.

In March 2011, the Company revalued its investment in NSX Holdings, Inc. as a result of an other-than-temporary impairment resulting in a full impairment totaling $0.5 million, which represented the carrying value of the investment. The investment was classified as level 3 as the fair value was based on both observable and unobservable inputs.

In December 2011, the Company, through DerivaTech Corporation, a wholly-owned subsidiary, acquired a 6.25% interest in IPXI Holdings, LLC ("IPXI") for $2.5 million. The Company contributed cash of $1.3 million and has accrued a liability of $1.2 million which is expected to become due in December 2012 and will increase the Company's share of IPXI to 10.0%. The investment, measured at fair value on a non-recurring basis, is classified as level 3 as the fair value was based on both observable and unobservable inputs.

NOTE 13 — LEGAL PROCEEDINGS

As of September 30, 2012, the end of the period covered by this report, the Company was subject to the various legal proceedings and claims discussed below, as well as certain other legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business.

The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and we disclose the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company's assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals.

Estimates of probable losses resulting from patent litigation involving the Company are inherently difficult to make, particularly when the Company's view of the case is significantly different than that expressed by the plaintiff. The Company has not recorded a liability related to damages in connection with these matters.

As of September 30, 2012, the Company does not think that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any litigation is inherently uncertain and an adverse outcome from certain matters could have a material effect on our earnings in any given reporting period. However, in the opinion of management, the ultimate liability is not expected to have a material effect on our financial position, liquidity or capital resources.

Index Options Litigation

On May 25, 2012, the Illinois Appellate Court (the “Appellate Court”) affirmed the ruling of the Circuit Court of Cook County, Illinois (the “Circuit Court”) granting CBOE, The McGraw-Hill Companies, Inc. and CME Group Index Services, LLC summary judgment against International Securities Exchange (“ISE”) and its parent company. On September 26, 2012, the Illinois Supreme Court denied ISE's Petition for Leave to Appeal. The summary judgment motion enjoined ISE from listing or providing an exchange trading market for options on the S&P 500 Index or the Dow Jones Industrial Average and

15

OCC from participating in the facilitation of such ISE index options and from issuing, clearing or settling the exercise of such ISE options (the “Injunction”). On November 2, 2012, the Circuit Court held that ISE's rule filing that purported to base options on the ISE Max SPY index would violate the Injunction.

Patent Litigation

ISE - C2

On August 15, 2012, C2 filed a new declaratory judgment complaint against ISE in the United States District Court for the Northern District of Illinois alleging that ISE's United States Patent No. 6,618,707, which is directed toward an automated exchange for trading derivative securities and is assigned to ISE, is not valid, is not infringed and is not enforceable.

NOTE 14 — SUBSEQUENT EVENTS

The Company announced that its board of directors declared a quarterly cash dividend of $0.15 per share. The dividend is payable December 21, 2012 to stockholders of record at the close of business on November 30, 2012.

Due to the impact of Hurricane Sandy, all of our exchanges were closed on Monday, October 29 and Tuesday, October 30, 2012, resulting in no trading activity on those days.

On November 2, 2012, the Circuit Court held that ISE's rule filing that purported to base options on the ISE Max SPY index would violate the Injunction (See Note 13 - Legal Proceedings).

• The Company’s market share of total exchange traded options contracts was 28.2% for the three months endedSeptember 30, 2012 compared with 26.9% for the same period in 2011.

• Total operating revenues decreased due to lower transaction fees and access fees, partially offset by higher exchange services and other fees, market data fees and other revenue.

• Total operating expenses decreased primarily due to lower royalty fees and trading volume incentives, partially offset by higher employee costs and outside services.

Transactions impacting our financial performance for the three months endedSeptember 30, 2012

• Effective August 1, 2012, CBOE increased its options regulatory fee rate and C2 implemented an options regulatory fee. The increase in the options regulatory fee is reflected in "Regulatory Fees" in the condensed consolidated statement of income.

• Fines increased due to a disciplinary action against a Trading Permit Holder. The increase in fines is reflected in "Other Revenue" in the condensed consolidated statement of income.

17

• Severance expense increased due to the elimination of staff positions. The increase in severance expense is reflected in "Employee Costs" in the condensed consolidated statement of income.

• Income tax expense decreased due to the recognition of certain income tax adjustments resulting from the recognition of significant discrete items. The income tax benefit is reflected in "Income Tax Provision" in the condensed consolidated statement of income.

Operating Revenues

Total operating revenues for the three months endedSeptember 30, 2012 were $128.3 million, a decrease of $15.3 million, or 10.7%, compared with the same period in 2011. The following summarizes changes in total operating revenues for the three months endedSeptember 30, 2012 compared to the same period in 2011.

	2012		2011		Inc./(Dec.)			Percent Change
			(in millions)
Transaction fees	$	86.6	$	109.8	$	(23.2	)	(21.1	)%
Access fees	16.0		16.9		(0.9		)	(5.3	)%
Exchange services and other fees	7.8		4.5		3.3			73.3	%
Market data fees	6.1		4.9		1.2			24.5	%
Regulatory fees	5.7		5.3		0.4			7.5	%
Other revenue	6.1		2.2		3.9			177.3	%
Total operating revenues	$	128.3	$	143.6	$	(15.3	)	(10.7	)%

Transaction Fees

Transaction fees decreased21.1% to $86.6 million for the three months endedSeptember 30, 2012, compared with $109.8 million for the same period in 2011. This decrease was due to a decrease of 22.1% in total trading volume, partially offset by an increase of 1.3% in average revenue per contract. Transaction fees accounted for 67.5% and 76.5% of total operating revenues for the three months endedSeptember 30, 2012 and 2011, respectively.

In 2012, the Company implemented several changes to its fee schedule to promote trading in various products. Adjustments were made to liquidity provider sliding scales, effectively decreasing per contract fees on multiply-listed options products and increasing per contract fees on proprietary products. For Clearing Trading Permit Holders that are proprietary firms, a single, fixed transaction fee for non-paired orders in products other than our proprietary option products was established in an effort to increase our market share. We implemented a Volume Incentive Program ("VIP") to reward firms who execute qualifying electronic, public customer, multiply-listed volume at CBOE in excess of certain thresholds, with a graduated schedule for higher tiers.

Our share of total exchange traded options contracts increased to 28.2% from 26.9% in the prior year period, while overall trading volume in the industry decreased. We believe the market share increase is primarily attributable to the fee changes and incentive programs implemented at the beginning of 2012. The Company expects market share to decrease over the remainder of 2012 due to increasing competitive pressures.

Overall trading volume is impacted by many factors which may or may not be in our control. These factors include: political and world events, market volatility, regulatory actions or considerations, availability of capital, competition, trading patterns or strategies, number of trading days in the period and seasonality.

Average revenue per contract, discussed in detail below, is impacted by our fee structure which includes volume based incentive programs, mix of products traded and the percentage of trading volume executed by customers as compared to professionals, market-makers, clearing trading permit holders and broker-dealers. The implementation of fee changes, which may increase or decrease our average revenue per contract, is primarily to ensure that we are competitive in the options marketplace and to ultimately improve and continue to drive order flow to our exchanges. We cannot predict the trading patterns of exchange participants but we can continue to price our products at levels that are competitive in our markets.

Trading Volume

Our average daily trading volume for the three months endedSeptember 30, 2012 was 4.34 million contracts, down 20.9% compared with 5.48 million for the same period in 2011. The Company experienced volume decreases across all options product categories. The significant growth in futures continued, primarily driven by futures contracts on the VIX Index. Total trading days for the three months ended September 30, 2012 and 2011 were sixty-three and sixty-four, respectively.

The following summarizes changes in total trading volume and average daily trading volume ("ADV") by product for the three months ended September 30, 2012 compared to the same period in 2011.

Average revenue per contract

The average revenue per contract was $0.317 for the three months endedSeptember 30, 2012, an increase of 1.3% compared with $0.313 for the same period in 2011. Average revenue per contract represents transaction fees divided by total contracts cleared.

The following summarizes average revenue per contract by product for the three months endedSeptember 30, 2012 compared to the same period in 2011.

	2012		2011		Percent Change
Equities	$	0.118	$	0.159	(25.8	)%

Futures	1.606		1.371		17.1	%
Total average revenue per contract	$	0.317	$	0.313	1.3	%

Certain factors contributed to the increase in total average revenue per contract for the three months endedSeptember 30, 2012 compared to the same period in 2011, including our rate structure and mix of products traded. Our rate structure includes sliding scales, volume discounts and limits on fees as part of our effort to increase liquidity and market share in both multiply-listed options products and, to a lesser extent, on our proprietary products. In general, the transaction fee changes implemented in 2012 increased the average revenue per contract on index options and futures and decreased the average revenue per contract for multiply-listed options products (equities and exchange-traded funds). We expect this trend to continue for the remainder of 2012. One of the fee changes implemented in 2012 contributing to the decrease in average revenue per contract for multiply-listed products was the VIP.

At September 30, 2012, there were approximately one hundred fifteen clearing firms, two of which cleared a combined 45% of our billings collected through the OCC for the three months ended September 30, 2012. The next largest clearing firm accounted for approximately 5% of our billings collected through the OCC. No one customer affiliated with either of the top two clearing firms represented more than 16% of the billings collected for the three months ended September 30, 2012 or 2011. Should a clearing firm withdraw, we believe the affiliated customer portion of that firm’s trading activity would likely transfer to another clearing firm.

The two largest clearing firms mentioned above clear the majority of the market-maker sides of transactions at CBOE, C2 and at all of the U.S. options exchanges. If either of these firms were to withdraw from the business of market-maker clearing, and market-makers were unable to make new clearing arrangements, this could create significant disruption to the U.S. options markets, including ours.

Access fees for the three months endedSeptember 30, 2012 and 2011 were $16.0 million and $16.9 million, respectively, representing 12.4% and 11.8% of total operating revenues, respectively. The decrease in access fees was primarily due to fee adjustments for market-maker trading permits, which lowered both the fee for monthly trading permits and pricing under the market-maker trading permit sliding scale in the current year period. Market-makers that commit to a minimum number of trading permits for the calendar year qualify for a discounted monthly rate.

The demand for trading permits could be impacted by seasonality and market fluctuations that affect trading volume.

Exchange Services and Other Fees

Exchange services and other fees for the three months endedSeptember 30, 2012increased73.3% to $7.8 million from $4.5 million for the same period in 2011. The increase was primarily due to pricing increases for services such as connectivity to CBOECommandthrough network access ports and client application services.

Market Data Fees

Market data fees increased 24.5% for the three months endedSeptember 30, 2012 to $6.1 million from $4.9 million for the same period in 2011. Market data fees represent income derived from OPRA as well as the Company’s market data services. OPRA and the Company's market data services for the three months endedSeptember 30, 2012 and 2011, were $3.6 million and $2.5 million and $3.1 million and $1.8 million, respectively. OPRA income is allocated through OPRA based on each exchange's share of total options transactions cleared. The Company’s share of OPRA income for the three months ended September 30, 2012 increased to 25.2% from 19.9% for the same period in 2011 resulting in an increase in OPRA income of $0.5 million. Revenue generated from the Company's market data services, which provide current and historical options and

20

futures data, increased $0.6 million resulting from an increase in subscribers.

Regulatory Fees

Regulatory fees increased7.5% for the three months endedSeptember 30, 2012 to $5.7 million from $5.3 million for the same period in 2011. The increase in regulatory fees primarily resulted from CBOE increasing its options regulatory fee rate and C2 implementing an options regulatory fee. This increase was partially offset by lower customer volume industry-wide as compared to the same period in 2011. The Company's regulatory fees are primarily based on the number of customer contracts traded throughout the listed United States options industry. Under the rules of each of our options exchanges, as required by the SEC, any revenue derived from regulatory fees and fines cannot be used for non-regulatory purposes.

Other Revenue

Other revenue increased$3.9 million for the three months endedSeptember 30, 2012 to $6.1 million from $2.2 million for the same period in 2011 which reflects fines assessed to trading permit holders resulting from disciplinary actions. Under the rules of each of our options exchanges, as required by the SEC, any revenue derived from regulatory fees and fines cannot be used for non-regulatory purposes.

Operating Expenses

Total operating expenses decreased$1.1 million, or 1.6%, to $67.5 million for the three months endedSeptember 30, 2012 from $68.6 million for the same period in 2011. This decrease was primarily due to lower royalty fees and trading volume incentives, partially offset by higher employee costs and outside services. As a percentage of operating revenues for the three months ended September 30, 2012 and 2011, operating expenses were 52.7% and 47.9%, respectively.

The following summarizes changes in operating expenses for the three months endedSeptember 30, 2012 compared to the same period in 2011.

	2012		2011		Inc./(Dec.)			Percent Change
			(in millions)
Employee costs	$	27.2	$	25.9	$	1.3		5.0	%
Depreciation and amortization	8.6		8.9		(0.3		)	(3.4	)%
Data processing	5.1		4.3		0.8			18.6	%
Outside services	9.1		6.9		2.2			31.9	%
Royalty fees	11.3		14.0		(2.7		)	(19.3	)%
Trading volume incentives	1.4		3.5		(2.1		)	(60.0	)%
Travel and promotional expenses	2.5		2.4		0.1			4.2	%
Facilities costs	1.3		1.1		0.2			18.2	%
Other expenses	1.0		1.6		(0.6		)	(37.5	)%
Total operating expenses	$	67.5	$	68.6	$	(1.1	)	(1.6	)%

Employee Costs

For the three months endedSeptember 30, 2012, employee costs were $27.2 million, or 21.2% of total operating revenues, compared with $25.9 million, or 18.1% of total operating revenues, for the same period in 2011. This represented an increase of $1.3 million, or 5.0%. The increase was primarily attributed to higher severance expense of $2.0 million resulting from the elimination of staff positions and higher salaries of $0.6 million due to increased headcount primarily for regulatory functions. These increases were partially offset by lower annual incentive compensation of $1.5 million and self-insurance medical expenses of $0.3 million. Total headcount, as compared to the beginning of 2012, is relatively unchanged as the addition of staff, primarily for regulatory functions, is mostly offset by the eliminated staff positions.

21

Depreciation and Amortization

Depreciation and amortization decreased by $0.3 million to $8.6 million for the three months endedSeptember 30, 2012 compared with $8.9 million for the same period in 2011. Depreciation and amortization charges represented 6.7% and 6.2% of total operating revenues for the three months ended September 30, 2012 and 2011, respectively.

Data Processing

Data processing expenses totaled $5.1 million and $4.3 million, representing 4.0% and 3.0% of total operating revenues for the three months endedSeptember 30, 2012 and 2011, respectively. The increase in data processing expenses is primarily due to an increase in hardware and software maintenance relating to the migration of the CBOE and CFE trading platform to New Jersey and other various software upgrades.

Outside Services

Expenses related to outside services increased to $9.1 million for the three months endedSeptember 30, 2012 from $6.9 million in the prior-year period and represented 7.1% and 4.8% of total operating revenues for the three months endedSeptember 30, 2012 and 2011, respectively. The $2.2 million increase primarily resulted from higher expenses for costs relating to legal proceedings, review of regulatory compliance and a settlement agreement with Realtime Data LLC. The terms of the settlement are confidential. The Company recorded an immaterial charge related to the settlement. The Company expects legal expenses to continue to trend higher resulting from legal proceedings.

Royalty Fees

Royalty fees for the three months endedSeptember 30, 2012 were $11.3 million compared with $14.0 million for the same period in 2011, a decrease of $2.7 million resulting from lower trading volume in licensed index products. Royalty fees represented 8.8% and 9.7% of total operating revenues for the three months ended September 30, 2012 and 2011, respectively.

Trading Volume Incentives

Trading volume incentives decreased by $2.1 million to $1.4 million for the three months endedSeptember 30, 2012 compared to $3.5 million for the same period in 2011. The decrease was primarily due to lower volume in multiply-listed options products (equities and exchange-traded funds), a modification in the criteria for contracts qualifying for certain quantity-based fee waivers and an adjustment to the fees paid by the Company for transactions linked to away exchanges.

Other Expenses

Other expenses for the three months endedSeptember 30, 2012 and 2011 were $1.0 million and $1.6 million, respectively. The decrease of $0.6 million was due to losses recorded in the prior year period on the disposal of equipment which did not recur in the current period.

Operating Income

As a result of the items above, operating income for the three months endedSeptember 30, 2012 was $60.8 million compared to $75.0 million for the same period in 2011, a decrease of $14.2 million.

Income before Income Taxes

Income before income taxes for the three months endedSeptember 30, 2012 was $60.5 million compared to $74.6 million for the same period in 2011, a decrease of $14.1 million.

Income Tax Provision

For the three months endedSeptember 30, 2012, the income tax provision was $14.7 million compared to $33.2 million for the same period in 2011. The effective tax rate was 24.4% and 44.6% for the three months endedSeptember 30, 2012 and 2011, respectively. The decrease in effective tax rate for the three months endedSeptember 30, 2012 compared to the prior year period is the result of the recognition of discrete items and the benefit of a new tax apportionment method enacted by Illinois. During the three months endedSeptember 30, 2012, the Company filed an amended return for 2008 and completed it return for 2011 and recognized, as a discrete item, a $7.7 million benefit for a Section 199 deduction for U.S. production

22

activities which encompasses all personal property including computer software. The prior year effective tax rate included the impact of an increase in the Illinois tax rate effective January 1, 2011 and a charge of $4.2 million taken to increase state-related uncertain tax positions. The Company expects to file amended tax returns for tax years 2009 and 2010 in the fourth quarter of 2012 which it believes will result in additional deductions and should further reduce the 2012 effective tax rate.

Net Income

As a result of the items above, net income allocated to common stockholders for the three months endedSeptember 30, 2012 was $45.2 million compared to $40.6 million for the same period in 2011, an increase of $4.6 million. Basic and diluted net income per share allocated to common stockholders were $0.52 and $0.45 for the three months endedSeptember 30, 2012 and 2011, respectively.

• The Company’s market share of total exchange traded options contracts was 28.4% for the nine months endedSeptember 30, 2012 compared with 26.7% for the same period in 2011. We believe the market share increase is primarily attributable to the fee changes implemented at the beginning of 2012.

• Total operating revenues decreased due to lower transaction fees and access fees partially offset by higher exchange services and other fees, market data fees and other revenue.

• Total operating expenses decreased primarily due to lower trading volume incentives, royalty fees and other expenses, partially offset by higher outside services, employee costs and travel and promotional expenses.

Certain factors contributed to the increase in total average revenue per contract for the nine months endedSeptember 30, 2012 compared to the same period in 2011, including our rate structure and mix of products traded. In general, the transaction fee changes implemented in 2012 increased the average revenue per contract on index options and futures and decreased average revenue per contract on multiply-listed options products (equities and exchange-traded funds).

Access Fees

Access fees for the nine months endedSeptember 30, 2012 and 2011 were $48.1 million and $51.6 million, respectively, representing 12.6% and 13.3% of total operating revenues, respectively.

Exchange Services and Other Fees

Exchange services and other fees for the nine months endedSeptember 30, 2012increased71.1% to $23.1 million from $13.5 million for the same period in 2011.

25

Regulatory Fees

Regulatory fees decreased 3.3% for the nine months endedSeptember 30, 2012 to $14.5 million from $15.0 million for the same period in 2011. The decrease is primarily due to lower volume of customer contracts industry-wide as compared to the same period in 2011 partially offset by the fee changes implemented on August 1, 2012.

Other Revenue

Other revenue increased $4.4 million for the nine months endedSeptember 30, 2012 to $11.4 million from $7.0 million for the same period in 2011 primarily due to an increase in fines assessed to trading permit holders resulting from disciplinary actions.

Operating Expenses

Total operating expenses were $197.9 million and $199.0 million for the nine months endedSeptember 30, 2012 and 2011, respectively. This decrease was primarily due to lower trading volume incentives, royalty fees and other expenses, partially offset by higher outside services, employee costs and travel and promotional expenses. As a percentage of operating revenues for the nine months endedSeptember 30, 2012 and 2011, operating expenses were 51.8% and 51.3%, respectively.

The following summarizes changes in operating expenses for the nine months endedSeptember 30, 2012 compared to the same period in 2011.

Employee Costs

For the nine months endedSeptember 30, 2012, employee costs were $77.8 million, or 20.3% of total operating revenues, compared with $76.2 million, or 19.6% of total operating revenues, for the same period in 2011. This represented an increase of $1.6 million, or 2.1%. The increase was primarily attributed to higher severance expense of $3.2 million and higher salaries of $1.2 million, partially offset by lower annual incentive compensation of $2.2 million.

Depreciation and Amortization

Depreciation and amortization decreased by $1.3 million to $25.3 million for the nine months endedSeptember 30, 2012 compared with $26.6 million for the same period in 2011.

Data Processing

Data processing expenses totaled $14.9 million and $13.7 million, representing 3.9% and 3.5% of total operating revenues for the nine months endedSeptember 30, 2012 and 2011, respectively. The increase in data processing expenses is primarily due to an increase in hardware and software maintenance relating to the migration of the trading platform and other various software upgrades.

26

Outside Services

Expenses related to outside services increased to $25.5 million for the nine months endedSeptember 30, 2012 from $20.6 million in the prior-year period and represented 6.7% and 5.3% of total operating revenues for the nine months endedSeptember 30, 2012 and 2011, respectively. The $4.9 million increase primarily resulted from higher fees for contract programmers, review of regulatory compliance, legal proceedings and a settlement agreement.

Royalty Fees

Royalty fees for the nine months endedSeptember 30, 2012 were $34.5 million compared with $35.5 million for the same period in 2011, a decrease of $1.0 million. This decrease is a direct result of the lower trading volume in licensed index products. Royalty fees represented 9.0% and 9.1% of total operating revenues for the nine months endedSeptember 30, 2012 and 2011, respectively.

Trading Volume Incentives

Trading volume incentives decreased by $6.6 million to $5.2 million for the nine months endedSeptember 30, 2012 compared to $11.8 million for the same period in 2011. The decrease was primarily due to lower volume in multiply-listed options products (equities and exchange-traded funds), modifications in the criteria for contracts qualifying for certain quantity-based fee waivers and adjustments to the fees paid by the Company for transactions linked to away exchanges.

Travel and Promotional Expenses

Travel and promotional expenses for the nine months endedSeptember 30, 2012 were $8.0 million compared with $6.5 million for the same period in 2011, an increase of $1.5 million. The increase was primarily due to higher advertising expenses and expenses related to other miscellaneous events.

Operating Income

As a result of the items above, operating income for the nine months endedSeptember 30, 2012 was $184.4 million compared to $188.9 million for the same period in 2011, a decrease of $4.5 million.

Income before Income Taxes

Income before income taxes for the nine months endedSeptember 30, 2012 and 2011 was $183.2 million and $187.7 million, respectively, resulting in a decrease of $4.5 million.

The effective tax rate was 35.8% and 42.7% for the nine months endedSeptember 30, 2012 and 2011, respectively. The decrease in effective tax rate for the nine months ended September 30,2012 compared to the prior year period is the result of a $7.7 million benefit due to the recognition a Section 199 deduction for U.S. production activities and the benefit of a new tax apportionment method for Illinois. The prior year effective tax rate included the impact of an increase in the Illinois tax rate and a charge of $4.2 million for state-related uncertain tax positions.

Net Income

As a result of the items above, net income allocated to common stockholders for the nine months endedSeptember 30, 2012 was $116.0 million compared to $105.3 million for the same period in 2011, an increase of $10.7 million.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 2012, total assets were $377.5 million, an increase of $49.6 million compared with $327.9 million at December 31, 2011. The following highlights factors that contributed to the change in total assets:

• Cash and cash equivalents increased by $25.4 million to $160.3 million at September 30, 2012 from $134.9 million at December 31, 2011, primarily due to cash generated from operations and the prepayment of liquidity provider transaction fees, partially offset by estimated tax payments of $69.4 million, treasury stock repurchases totaling $49.7 million and dividend payments totaling $34.6 million. Our cash and cash equivalents at September 30, 2012 were primarily composed of investments in institutional U.S. Treasury and prime money market funds.

• Accounts receivable increased by $7.8 million to $45.4 million at September 30, 2012 from $37.6 million at December 31, 2011, primarily due to higher trading volume in September 2012 compared to December 2011.

• Income taxes receivable increased $10.1 million primarily due to higher estimated payments which did not include the impact of Section 199 deductions related to prior years.

At September 30, 2012, total liabilities were $102.0 million, an increase of $10.4 million from the December 31, 2011 balance of $91.6 million. This increase was primarily due to increases in deferred revenue and other liabilities of $8.4 million and income taxes payable of $6.0 million, partially offset by a decrease of $7.8 million in accounts payable and accrued expenses.

Historically, we have financed our operations, capital expenditures and other cash needs through cash generated from operations. Cash requirements principally consist of funding operating expenses and capital expenditures and include actual and anticipated quarterly dividend payments and unrestricted common stock repurchases under the announced programs. We expect to use cash on hand at September 30, 2012 and funds generated from operations to continue to meet our cash requirements.

Cash Flows

Operating Activities

Net cash flows provided by operating activities was $140.9 million and $164.3 million for the first nine months of 2012 and 2011, respectively. The decrease in net cash flows provided by operating activities was primarily due to an increase in income taxes receivable resulting from the recognition of Section 199 deductions related to prior years and a decrease in deferred revenue and other liabilities. The decrease in deferred revenue primarily results from the removal of certain index products and reduction in volume thresholds in the liquidity provider sliding scale.

Net cash flows provided by operating activities was $23.2 million higher than net income for the nine months ended September 30,2012. The net increase was mainly a result of deferred revenue and other liabilities of $8.4 million, primarily due to the prepayment of transaction fees that are amortized over the year, and non-cash expenses of $25.3 million and $9.0 million for depreciation and amortization and stock-based compensation, respectively. These amounts were partially offset by an increase in income taxes receivable of $10.1 million.

Net cash flows used in investing activities were $28.1 million and $23.4 million for the nine months ended September 30,2012 and 2011, respectively. Expenditures for capital and other assets totaled $26.8 million and $23.5 million for the nine months ended September 30,2012 and 2011, respectively, primarily representing purchases of systems hardware and software.

Financing Activities

Net cash flows used in financing activities totaled $87.5 million and $47.4 million for the nine months ended September 30,2012 and 2011, respectively. The increase of $40.0 million in net cash flows used in financing activities is primarily due to an increase in stock repurchases of $34.9 million and an increase in quarterly dividend payments of $5.1 million.

28

For the nine months ended September 30,2012, net cash flows used in financing activities consisted of $34.6 million for the payment of quarterly dividends, $49.7 million in unrestricted common stock purchases under the Company's share repurchase program and $3.1 million for purchases of shares of unrestricted common stock surrendered in the second quarter of 2012 to satisfy employees' tax obligations upon the vesting of restricted stock.

Dividends

The Company’s expectation is to continue to pay dividends, with any such dividend based on prior year’s net income adjusted for certain items. The decision to pay a dividend, however, remains within the discretion of our Board of Directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our Board of Directors deems relevant. Future credit facilities, other future debt obligations and statutory provisions may limit, or in some cases prohibit, our ability to pay dividends.

Share Repurchase Program

On August 2, 2011, the Company announced that its board of directors had approved a share repurchase program that authorizes the Company to purchase up to $100 million of its unrestricted common stock. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

On July 31, 2012, the Company announced that its board of directors had approved the repurchase of an additional $100 million of its outstanding unrestricted common stock. This program is in addition to any amount remaining under the August 2011 authorization.

From August 2011 through September 30, 2012, the Company has purchased 3,707,424 shares of unrestricted common stock at an average cost per share of $26.09 totaling $96.7 million in purchases under the program.

For the nine months ended September 30,2012, the Company has purchased 1,871,424 shares of unrestricted common stock at an average cost per share of $26.58 totaling $49.7 million in purchases under the program. The Company did not repurchase any shares in the three months endedSeptember 30, 2012.

Commercial Commitments and Contractual Obligations

The Company leases office space in downtown Chicago, Illinois for its Regulatory Services Division, in a suburb of Chicago for its disaster recovery center, in New York for certain marketing activities and in New Jersey for our trading platform, with lease terms remaining from 20 months to 55 months as of September 30, 2012. Total rent expense related to the lease obligations for the nine months ended September 30,2012 and 2011 were $2.6 million and $2.5 million, respectively. The Company does not expect the upgrade of our trading platform nor the move of our trading platform to Secaucus, New Jersey to result in any material commercial commitments or contractual obligations.

Future minimum payments under these non-cancelable leases were as follows at September 30, 2012 (in thousands):

	Total		Less than 1 year		1-3 years		3-5 years
Operating leases	$	10,584	$	2,642	$	4,655	$	3,287
Contractual obligations	341		341		—		—
Total	$	10,925	$	2,983	$	4,655	$	3,287

In addition to the non-cancelable leases, the Company has licensing agreements with various licensors containing annual minimum fee requirements totaling $23.8 million for the next five years and $1.7 million for the five years thereafter.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

We are subject to certain market risks, including changes in interest rates and inflation. There have been no material changes in our market risk from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2011.

Item 4.  Controls and Procedures

Disclosure controls and procedures

In accordance with Rule 13a-15(b) of the Securities Exchange Act of 1934 (the “Exchange Act”), the Company’s management, with the participation of the Company’s Chairman of the Board and Chief Executive Officer and Executive Vice

President and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures for the three months ended September 30, 2012. Based upon their evaluation of these disclosure controls and procedures, the Chairman of the Board and Chief Executive Officer and the Executive Vice President and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the three months ended September 30, 2012 to ensure that information required to be disclosed by the Company in the reports that it files or submits is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and financial officers, as appropriate, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the three months ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

30

PART II. OTHER INFORMATION

Item 1.  Legal Proceedings

As of September 30, 2012, the end of the period covered by this report, the Company was subject to the various legal proceedings and claims discussed in its Annual Report on Form 10-K for the year ended December 31, 2011, and subsequent filings with the SEC and discussed below, as well as certain other legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business.

The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and we disclose the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company's assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals.

Estimates of probable losses resulting from patent litigation involving the Company are inherently difficult to make, particularly when the Company's view of the case is significantly different than that expressed by the plaintiff. The Company has not recorded a liability related to damages in connection with these matters.

As of September 30, 2012, the Company does not think that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any litigation is inherently uncertain and an adverse outcome from certain matters could have a material effect on our earnings in any given reporting period. However, in the opinion of management, the ultimate liability is not expected to have a material effect on our financial position, liquidity or capital resources.

Index Options Litigation

On May 25, 2012, the Illinois Appellate Court (the “Appellate Court”) affirmed the ruling of the Circuit Court of Cook County, Illinois (the “Circuit Court”) granting CBOE, The McGraw-Hill Companies, Inc. and CME Group Index Services, LLC summary judgment against International Securities Exchange (“ISE”) and its parent company. On September 26, 2012, the Illinois Supreme Court denied ISE's Petition for Leave to Appeal. The summary judgment motion enjoined ISE from listing or providing an exchange trading market for options on the S&P 500 Index or the Dow Jones Industrial Average and OCC from participating in the facilitation of such ISE index options and from issuing, clearing or settling the exercise of such ISE options (the “Injunction”). On November 2, 2012, the Circuit Court held that ISE's rule filing that purported to base options on the ISE Max SPY index would violate the Injunction.

Patent Litigation

ISE - C2

On August 15, 2012, C2 filed a new declaratory judgment complaint against ISE in the United States District Court for the Northern District of Illinois alleging that ISE's United States Patent No. 6,618,707, which is directed toward an automated exchange for trading derivative securities and is assigned to ISE, is not valid, is not infringed and is not enforceable.

Item 1A. Risk Factors

Other than as described below, there have been no material updates to the Risk Factors as set forth in Item 1A. of our Annual Report on Form 10-K, filed with the SEC on February 28, 2012.

Computer and communications systems failures and capacity constraints could harm our reputation and our business.

We must operate, monitor and maintain our computer systems and network services, including those related to our

electronic trading systems, so that they function in a reliable manner. A failure to do so could have a material adverse effect on the functionality and reliability of our market and our reputation, business, financial condition and operating results. System failure or degradation could lead our customers to file formal complaints with industry regulators, file lawsuits against us or cease doing business with us. It could also lead regulators to initiate inquiries or proceedings for failure to comply with

31

applicable laws and regulations. Any of these effects could harm our reputation, business, financial condition and operating results. In the fourth quarter of 2012, the Company is moving its trading platform from its principal location to New Jersey. In the event connections are not working at the new location, we will be required to revert the systems to our current principal location.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

(c) The table below shows the purchases of equity securities by the Company in the three months ended September 30, 2012, reflecting the purchase of unrestricted common stock under the Company's share repurchase program:

(1) On August 2, 2011, the Company announced that its board of directors had adopted a share repurchase plan.  Under this plan, the Company is authorized to repurchase up to $100 million in its unrestricted common stock, including on the open market and in privately negotiated transactions. There can be no assurance as to the number of additional shares the Company will repurchase. The timing and extent to which the Company repurchases its shares will depend upon, among other things, market conditions, share price, liquidity targets, regulatory requirements and other factors. Share repurchases may be commenced or suspended at any time or from time to time without prior notice, and the share repurchase plan does not currently have an expiration date.

(2) On July 31, 2012, the Company's board of directors authorized the Company to repurchase an additional $100 million of its outstanding unrestricted common stock.

Description Of Business

DESCRIPTION OF BUSINESS

CBOE Holdings is the holding company of registered securities exchanges, subject to oversight by the SEC, and of a designated contract market subject to the oversight of the CFTC.

The primary business of the Company is the operation of markets for the trading of listed options contracts on three broad product categories: 1) the stocks of individual corporations (equity options), 2) various market indexes (index options) and 3) other exchange-traded products such as exchange-traded funds (ETF options) and exchange-traded notes (ETN options). We also offer futures through a futures market. The Company owns and operates three stand-alone exchanges, but reports the results of its operations in one reporting segment. CBOE is our largest exchange by volume and offers trading for listed options through a single system that integrates electronic trading and traditional open outcry trading on our trading floor in Chicago. This integration of electronic trading and traditional open outcry trading into a single market is known as our Hybrid trading model. C2, our all-electronic exchange, also offers trading for listed options, but with a different market model and fee schedule than CBOE. Finally, CFE, our all-electronic futures exchange, offers futures on the CBOE Volatility Index (the VIX Index), as well as on other products. All of our exchanges operate on our proprietary technology platform known as CBOECommand.

In September 2012, the Company announced plans to establish a CFE technology hub in London which will provide European firms a cost-efficient way to send and receive CFE data and to execute trades.

Earnings Per Share [Abstract]

New Income per Common Share

NET INCOME PER COMMON SHARE

The unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents, whether paid or unpaid, are participating securities and are included in the computation of net income per common share pursuant to the two-class method. Our restricted stock awards granted to officers, directors and employees qualify as participating securities.

The Company computes net income per common share using the two-class method, which is an allocation formula that determines the net income for common shares and participating securities. Under the authoritative guidance, the presentation of basic and diluted earnings per share is required for each class of common stock and not for participating securities. As such, the Company presents basic and diluted net income per share for its one class of common stock.

 The computation of basic net income allocated to common stockholders is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to the participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine basic net income per common share.

The dilutive effect of participating securities is calculated using the more dilutive of the treasury stock or the two-class method. Diluted net income per common share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

The following table reconciles net income allocated to common stockholders and the number of shares used to calculate the basic and diluted net income per common share for the three and nine months ended September 30, 2012 and 2011:

Income Taxes

INCOME TAXES

For the three and nine months ended September 30, 2012 and 2011, the Company recorded income tax provisions of $14.7 million and $33.2 million and $65.5 million and $80.1 million, respectively. The effective tax rate for the nine months ended September 30,2012 and 2011 was 35.8% and 42.7%, respectively. The decrease in effective tax rate for the nine months ended September 30,2012 compared to the prior year period is the result of the recognition of discrete items and the benefit of a new tax apportionment method enacted by Illinois. During the three months ended September 30, 2012 , the Company filed an amended return for 2008 and completed it return for 2011 and recognized, as a discrete item, a $7.7 million benefit for a Section 199 deduction for U.S. production activities which encompasses all personal property including computer software. The Company expects to file amended tax returns for tax years 2009 and 2010 in the fourth quarter of 2012.

The prior year effective tax rate included the impact of an increase in the Illinois tax rate effective January 1, 2011 and a charge of $4.2 million taken to increase state-related uncertain tax positions.

As of September 30, 2012 and December 31, 2011, the Company had $17.0 million and $11.4 million, respectively, of uncertain tax positions excluding interest and penalties, which, if recognized in the future, would affect the annual effective income tax rate. Reductions to uncertain tax positions primarily from the lapse of the applicable statutes of limitations during the next twelve months are estimated to be approximately $3.6 million, not including any potential new additions.

Estimated interest costs and penalties, which are classified as part of the provision for income taxes in the Company’s condensed consolidated statements of income, were $0.2 million and $(0.2) million for the three months ended September 30, 2012 and 2011. For the nine months ended September 30, 2012 the total was $0.5 million. The amount for the nine months ended September 30, 2011 is immaterial. Accrued interest and penalties were $1.2 million and $0.8 million as of September 30, 2012 and December 31, 2011.

The Company is subject to U.S. federal tax, Illinois, New Jersey and New York state taxes and Washington D.C. taxes, as well as other local jurisdictions. The Company has open tax years from 2007 on for New York, 2008 on for federal and Illinois, and 2009 on for New Jersey and Washington, D.C. The Company's tax returns have been examined by the Internal Revenue Service through 2009 and the Illinois Department of Revenue through 2008. Specific line items for the 2008 tax year are being examined by the Internal Revenue Service and the Illinois Department of Revenue. The Company is currently under audit by the Internal Revenue Service for 2010, the State of New York for the 2007 through 2009 tax years and the State of Illinois for the 2009 and 2010 tax years.

Share-based Compensation [Abstract]

Stock-Based Compensation

STOCK-BASED COMPENSATION

Stock-based compensation is based on the fair value of the award on the date of grant, which is recognized over the related service period, net of estimated forfeitures. The service period is the period over which the related service is performed, which is generally the same as the vesting period.

On June 14, 2012, the Company granted 38,990 shares of restricted stock to non-employee members of the board of directors at a fair value of $27.33 per share, the closing price of the Company's stock on the grant date. The shares have a one year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. On August 15, 2012, the Company granted 8,163 shares of restricted stock to certain employees at a fair value of $28.98 per share, the closing price of the Company's stock on the grant date. The shares have a three year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. Unvested portions of the restricted stock will be forfeited if the member leaves the board or the employee leaves the company prior to the applicable vesting date, except in limited circumstances.

For the three and nine months ended September 30, 2012 and 2011, the Company recognized $3.1 million and $3.0 million and $9.0 million and $9.6 million of stock-based compensation expense, respectively. The nine months ended September 30, 2012 and 2011 includes accelerated stock-based compensation expense of $0.2 million and $0.5 million, respectively, resulting from departures from the board of directors. Stock-based compensation expense is included in employee costs in the condensed consolidated statements of income.

As of September 30, 2012, the Company had unrecognized stock-based compensation of $20.6 million.  The remaining unrecognized stock-based compensation is expected to be recognized over a weighted average period of 20.2 months. The Company is projecting a forfeiture rate of 5%.

The activity in the Company’s restricted stock for the nine months ended September 30,2012 was as follows:

	Number of Shares of Restricted Stock		Weighted Average Grant-Date Fair Value
Unvested restricted stock at January 1, 2012	1,252,239		$	29.00
Granted	47,153		27.62

Legal Proceedings [Abstract]

Legal Proceedings

LEGAL PROCEEDINGS

As of September 30, 2012, the end of the period covered by this report, the Company was subject to the various legal proceedings and claims discussed below, as well as certain other legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business.

The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and we disclose the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for our financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company's assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals.

Estimates of probable losses resulting from patent litigation involving the Company are inherently difficult to make, particularly when the Company's view of the case is significantly different than that expressed by the plaintiff. The Company has not recorded a liability related to damages in connection with these matters.

As of September 30, 2012, the Company does not think that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any litigation is inherently uncertain and an adverse outcome from certain matters could have a material effect on our earnings in any given reporting period. However, in the opinion of management, the ultimate liability is not expected to have a material effect on our financial position, liquidity or capital resources.

Index Options Litigation

On May 25, 2012, the Illinois Appellate Court (the “Appellate Court”) affirmed the ruling of the Circuit Court of Cook County, Illinois (the “Circuit Court”) granting CBOE, The McGraw-Hill Companies, Inc. and CME Group Index Services, LLC summary judgment against International Securities Exchange (“ISE”) and its parent company. On September 26, 2012, the Illinois Supreme Court denied ISE's Petition for Leave to Appeal. The summary judgment motion enjoined ISE from listing or providing an exchange trading market for options on the S&P 500 Index or the Dow Jones Industrial Average and OCC from participating in the facilitation of such ISE index options and from issuing, clearing or settling the exercise of such ISE options (the “Injunction”). On November 2, 2012, the Circuit Court held that ISE's rule filing that purported to base options on the ISE Max SPY index would violate the Injunction.

Patent Litigation

ISE - C2

On August 15, 2012, C2 filed a new declaratory judgment complaint against ISE in the United States District Court for the Northern District of Illinois alleging that ISE's United States Patent No. 6,618,707, which is directed toward an automated exchange for trading derivative securities and is assigned to ISE, is not valid, is not infringed and is not enforceable.

Basis of Presentation

BASIS OF PRESENTATION

These interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of operating revenues and expenses. On an ongoing basis, the Company evaluates its estimates, including those related to matters that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. These estimates are based on management’s knowledge and judgments, historical experience and observance of trends in particular matters. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented have been included. The results of operations for interim periods are not necessarily indicative of the results of operations for the full year.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Disclosures

FAIR VALUE MEASUREMENTS

Fair value is the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk.

The Company applied FASB ASC 820, Fair Value Measurement and Disclosure (formerly, FASB Statement No. 157, Fair Value Measurements), which provides guidance for using fair value to measure assets and liabilities by defining fair value and establishing the framework for measuring fair value. ASC 820 applies to financial and nonfinancial instruments that are measured and reported on a fair value basis. The three-level hierarchy of fair value measurements is based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair-value hierarchy requires the use of observable market data when available and consists of the following levels:

• Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities.

• Level 2—Observable inputs, either direct or indirect, not including Level 1, corroborated by market data or based upon quoted prices in non-active markets.

• Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability.

The Company has included a tabular disclosure for financial assets that are measured at fair value on a recurring basis in the condensed consolidated balance sheet as of September 30, 2012 and December 31, 2011. The Company holds no financial liabilities that are measured at fair value on a recurring basis.

In March 2011, the Company revalued its investment in NSX Holdings, Inc. as a result of an other-than-temporary impairment resulting in a full impairment totaling $0.5 million, which represented the carrying value of the investment. The investment was classified as level 3 as the fair value was based on both observable and unobservable inputs.

In December 2011, the Company, through DerivaTech Corporation, a wholly-owned subsidiary, acquired a 6.25% interest in IPXI Holdings, LLC ("IPXI") for $2.5 million. The Company contributed cash of $1.3 million and has accrued a liability of $1.2 million which is expected to become due in December 2012 and will increase the Company's share of IPXI to 10.0%. The investment, measured at fair value on a non-recurring basis, is classified as level 3 as the fair value was based on both observable and unobservable inputs.
