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 the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of this report. 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, 2015, 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 the risks that are material to us, 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 and trade certain index options and futures products;

economic, political and market conditions;

compliance with legal and regulatory obligations, including our obligations under the Consent Order;

increasing price competition in our industry;

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

legislative or regulatory changes;

increasing competition by foreign and domestic entities;

our dependence on third party service providers;

our index providers' ability to perform under our agreements;

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 transaction traffic, including significant increases, without failure or degradation of performance of our systems;

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

the accuracy of our estimates and expectations;

our ability to maintain access fee revenues;

our ability to meet our compliance obligations, including managing potential conflicts between our regulatory responsibilities and our for-profit status;

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

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

our ability to manage our growth and strategic acquisitions or alliances ~~effectively.~~effectively:

the satisfaction of the conditions precedent to the consummation of our proposed acquisition of Bats Global Markets, Inc. (“Bats”), including, without limitation, the receipt of stockholder and regulatory approvals (including clearance by antitrust authorities necessary to complete the proposed transaction) on the terms desired or anticipated;

unanticipated difficulties or expenditures relating to the proposed transaction, including, without limitation, difficulties that result in the failure to realize expected synergies, efficiencies and cost savings from the proposed transaction within the expected time period (if at all), whether in connection with integration, combining trading platforms, broadening distribution of product offerings or otherwise;

our ability to maintain an investment grade credit rating and obtain permanent financing for the proposed transaction on the anticipated terms and schedule;

risks relating to the value of our shares to be issued in the proposed transaction;

disruptions of our and Bats’ current plans, operations and relationships with market participants caused by the announcement and pendency of the proposed transaction;

potential difficulties in our and Bats’ ability to retain employees as a result of the announcement and pendency of the proposed transaction; and

legal proceedings that may be instituted against us and Bats following announcement of the proposed transaction.

We caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this filing. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

CBOE HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the three and ~~six~~nine months ended ~~June~~September 30, 2016 and 2015

(Unaudited)

NOTE 1 —DESCRIPTION OF BUSINESS

CBOE Holdings, Inc. is the holding company for Chicago Board Options Exchange, Incorporated, CBOE Futures Exchange, LLC, C2 Options Exchange, Incorporated and other subsidiaries, including our majority ownership in CBOE Vest Financial Group Inc. ("Vest").

The Company's principal business is operating markets that offer for trading options on various market indexes (index options), mostly on an exclusive basis, and futures contracts, as well as on non-exclusive "multiply-listed" options, such as options on the stocks of individual corporations (equity options) and options on other exchange-traded products (ETP options), such as exchange-traded funds (ETF options) and exchange-traded notes (ETN options). The Company operates CBOE, CFE and C2 as stand-alone exchanges, but reports the results of its operations in a single reporting segment.

CBOE is our primary options market and offers trading in 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 exchange is known as our Hybrid trading model. CFE, our all-electronic futures exchange, offers trading of futures on the VIX Index and other products. C2 is our all-electronic exchange that also offers trading ~~for~~of listed options, and may operate with a different market model and fee structure than CBOE. All of our exchanges operate on our proprietary technology platform known as CBOE Command.

CBOE Holdings and Bats Global Markets, Inc. (“Bats”), a leading global operator of securities exchanges and other electronic markets enabled by world-class technology, entered into an Agreement and Plan of Merger, dated as of September 25, 2016 (the “Merger Agreement”), providing, among other things, that, upon the terms and subject to the conditions set forth in the Merger Agreement, a wholly-owned subsidiary of CBOE Holdings will merge with and into Bats, with Bats surviving as a wholly-owned subsidiary of CBOE Holdings (the “Merger”). The Merger Agreement also provides that, immediately following the effective time of the Merger, Bats, as the surviving corporation from the Merger, will merge with and into CBOE V, LLC (“Merger LLC”), a wholly-owned subsidiary of CBOE Holdings, Inc. (the “Subsequent Merger”), with Merger LLC surviving the Subsequent Merger as a wholly-owned subsidiary of CBOE Holdings.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of voting common stock of Bats, par value $0.01 per share (“Bats Voting Common Stock”), and each share of non-voting common stock of Bats, par value $0.01 per share (“Bats Non-Voting Common Stock” and, together with the Bats Voting Common Stock, “Bats Common Stock”), issued and outstanding immediately prior to the Effective Time (other than shares held by CBOE Holdings, Bats or any of their respective subsidiaries, shares held by any holder of Bats Common Stock who is entitled to demand and properly demands appraisal of such shares under Delaware law and unvested restricted shares of Bats Common Stock granted under any Bats equity incentive plan) will convert into, at the election of the holder of such share, subject to proration and adjustment, either (i) 0.3201 of a share of common stock of CBOE Holdings, par value $0.01 per share (“CBOE Holdings Common Stock”), and $10.00 in cash (the “Mixed Consideration”), (ii) an amount of cash, without interest (the “Cash Consideration”), equal to the sum (rounded to two decimal places) of (a) $10.00 and (b) the product obtained by multiplying 0.3201 by the volume-weighted average price (rounded to four decimal places) of shares of CBOE Holdings Common Stock on the NASDAQ Stock Market LLC for the ten consecutive trading days ending on the second full trading day prior to the Effective Time (the “Closing VWAP”), or (iii) a number of shares of CBOE Holdings Common Stock (the “Stock Consideration”) equal to the sum of (a) 0.3201 and (b) the quotient (rounded to four decimal places) obtained by dividing $10.00 by the Closing VWAP. Holders of Bats Common Stock who do not make an election will receive the Mixed Consideration. The consideration to be paid to holders of Bats Common Stock electing to receive the Cash Consideration or the Stock Consideration in connection with the Merger is subject to automatic adjustment, as applicable, to ensure that the total amount of cash paid and the total number of shares of CBOE Holdings Common Stock issued in the Merger is the same as what would be paid and issued if all holders of Bats Common Stock were to receive the Mixed Consideration at the Effective Time.

Financial Conduct Authority and (iv) other customary closing conditions. Bats' and CBOE Holdings' directors and officers have signed supportive voting agreements. The Merger is expected to close in the first half of 2017.

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, 2015.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, valuation of redeemable noncontrolling interests and reported amounts of revenues and expenses. On an ongoing basis, management evaluates its estimates based upon historical experience, observance of trends, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

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.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In addition, the ASU provides guidance on accounting for certain revenue-related costs including when to capitalize costs associated with obtaining and fulfilling a contract. ASU 2014-09 provides companies with two implementation methods. Companies can choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The FASB deferred the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. Early adoption of the standard is permitted, but not before the original effective date of December 15,

2016. The Company is in the process of evaluating this guidance, though we do not expect it will materially impact our consolidated balance sheets, statements of income, comprehensive income or cash flows.

In September 2015, the FASB issued ASU 2015-16, Business Combinations. This standard simplifies the accounting for adjustments made to provisional amounts recognized in a business combination. First, it requires that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer also should record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. The amendments should be applied prospectively to adjustments to provisional amounts that are identified after December 15, 2015 and that are within the measurement period. Upon transition, an entity would be required to disclose the nature of, and reason for, the change in accounting principle. An entity would provide that disclosure in the first annual period of adoption and in the interim periods within the first annual period. The Company has adopted this guidance, though we do not expect it will materially impact our consolidated balance sheets, statements of income, comprehensive income or cash flows.

In February 2016, the FASB issued ASU 2016-02, Leases. This update requires a lessee to recognize on the balance sheet a liability to make lease payments and a corresponding right-of-use asset. The guidance also requires certain qualitative and quantitative disclosures about the amount, timing and uncertainty of cash flows arising from leases. This update is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted. The Company is in the process of evaluating this guidance, though we do not expect it will materially impact our consolidated balance sheets, statements of income, comprehensive income or cash flows.

In March 2016, the FASB issued ASU 2016-09, Compensation — Stock Compensation. This standard simplifies several aspects of the accounting for stock-based payment transactions, including the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016 and can be applied either prospectively, retrospectively or using a modified retrospective transition method, depending on the area covered in this update. Early adoption is permitted. The Company is in the process of evaluating this guidance, though we do not expect it will materially impact our consolidated balance sheets, statements of income, comprehensive income or cash flows.

In September 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) — Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force). This standard addresses stakeholders’ concerns regarding diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics.In particular, ASU No. 2016-15 addresses eight specific cash flow issues in an effort to reduce this diversity in practice: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon bonds; (3) contingent consideration payments made after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows and application of the predominance principle. For public business entities that are SEC filers, the amendments are effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. Note that early adoption is permitted for all entities, including adoption during an interim period. The Company is in the process of evaluating this guidance, though we do not expect it will materially impact our consolidated balance sheets, statements of income, comprehensive income or cash flows.

~~3. ACQUISITIONS -~~NOTE 3 — GOODWILL AND INTANGIBLE ASSETS

CBOE Vest Financial Group Inc.

In January 2016, the Company, through its subsidiary CBOE Vest, LLC, acquired a majority of the outstanding equity of Vest, an asset management firm that provides options-based investments through structured protective strategies and innovative technology solutions which allows for enhanced integration of our proprietary products, strategy indexes and options expertise. The purchase price consisted of $18.9 million in cash, reflecting payments of $14.9 million to former stockholders and $4.0 million to Vest for newly issued shares, and represented an ownership interest of 60% resulting in the consolidation of the operations. The purchase price was allocated on a preliminary basis, subject to final allocation, to the assets acquired based on their fair values at the acquisition date.



(amounts in thousands)
Purchase Price	$	18,900

Fair Value of Assets Acquired:
Cash	$	4,700
Intangible assets	8,000
Goodwill	18,800
Total Assets Acquired	$	31,500
Redeemable noncontrolling interests	12,600
Net Assets Acquired	$	18,900

The remaining 40% noncontrolling interest is held by the remaining Vest stockholders. The remaining Vest stockholders have a put option that can be exercised to Vest and Vest has a call option that can be exercised to the remaining stockholders. The put and call options can be exercised after five years though they could be accelerated by certain employment-related actions. The combination of the noncontrolling interest and a redemption feature resulted in a redeemable noncontrolling interest, which is classified outside of permanent equity on the condensed consolidated balance sheet.

In addition to the tangible and intangible assets, goodwill totaling $18.8 million was recorded in connection with the acquisition. Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents potential future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill is not expected to be deductible for tax purposes.

Pro forma financial information has not been provided as the Vest acquisition is not material to our consolidated

balance sheets, statements of income, comprehensive income or cash flows and did not meet the conditions of a significant

subsidiary under Rule 1-02 of Regulation S-X.

Vest - Intangible Assets

Livevol, Inc.

OnAs a result of our acquisition of Livevol in August 7, 2015, we recorded goodwill and intangible assets totaling $7.7 million and $2.6 million, respectively.

("Livevol"), which included Livevol Core, Livevol Pro and Livevol X trading analytics platforms, as well as Livevol Enterprise and other market data solutions products. The purchase price consisted of $7.0 million cash, including $4.0 million paid to existing Livevol debt holders and $3.0 million to Livevol owners, upon closing plusrecorded contingent consideration of $3.4 million, which was based on management's estimate of the achievement by Livevol of certain performance targets ~~measured~~ at nine and eighteen months from the acquisition ~~date of August 7, 2015. The purchase price was allocated on a preliminary basis, subject to final allocation, to the assets acquired based on their fair values at the acquisition~~ date.

NOTE 4 — DEBT

In connection with entering into the Merger Agreement, CBOE Holdings entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or any of its designated affiliates) (Bank of America, N.A., and other such financial institutions that accede as lender to such debt commitment letter in accordance with its terms are referred to herein as the “Lenders”), which provides that, subject to the satisfaction and waiver of certain conditions which are usual and customary for financing of this type, the Lenders are committed to provide debt financing for the purposes of funding (i) the cash consideration to be paid in the transactions contemplated by the Merger Agreement, (ii) the refinancing of certain existing indebtedness of Bats and its subsidiaries and (iii) related fees and expenses, which debt financing consists of a senior unsecured 364-day bridge loan facility in an aggregate principal amount of up to $1.65 billion to the extent CBOE Holdings fails to generate gross cash proceeds in an aggregate principal amount of up to $1.65 billion from permanent financing including in the form of a senior unsecured term loan facility and the issuance of senior unsecured notes on or prior to the consummation of the transaction contemplated by the Merger Agreement. On September 26, 2016, the Company paid commitment and structuring fees of $5.0 million that will be amortized over the period prior to the closing of the transaction that is expected to occur in the first half of 2017.

NOTE 5 — REDEEMABLE NONCONTROLLING INTEREST

Redeemable noncontrolling interests are reported on the condensed consolidated balance sheets in mezzanine equity in "Redeemable Noncontrolling Interests." We recognize changes to the redemption value of redeemable noncontrolling interests as they occur and adjust the carrying value to equal the redemption value at the end of each reporting period. The resulting increases or decreases in the estimated redemption amount are affected by corresponding charges or credits against retained earnings, or in the absence of retained earnings, additional paid in capital. The redemption amounts have been estimated based on the fair value of the majority-owned subsidiary, determined based on a weighting of the discounted cash flow and other economic factors.

For the ~~six~~nine months ended ~~June~~September 30, 2016, the following reflects changes in our redeemable noncontrolling interests (in thousands):


	Redeemable Noncontrolling Interest			Redeemable Noncontrolling Interest
Balance as of January 1, 2016	$	—		$	—
Increase due to acquiring majority of outstanding equity of Vest	12,600			12,600
Net loss attributable to redeemable noncontrolling interest	(523		)	(792		)
Redemption value adjustment	523			792
Balance as of June 30, 2016	$	12,600
Balance as of September 30, 2016				$	12,600

NOTE 56 — NET INCOME PER COMMON SHARE

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 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 net income per share allocated to common stockholders.

The computation of diluted earnings per 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 dilutive effect is calculated using the more dilutive of the two-class or treasury stock method.

Additionally, in accordance with accounting guidance, the change in the redemption value for the noncontrolling interest in Vest reduces net income allocated to common shareholders.

For the periods presented, the Company did not have shares of restricted stock or restricted stock units that would have an anti-dilutive effect on the computation of diluted net income per common share.

In order to complete the Company's proposed acquisition of Bats, shares of CBOE Holdings common stock are to be issued upon conversion of shares of Bats common stock in the Merger. Based on the number of shares of our common stock and Bats common stock outstanding on September 23, 2016, immediately following the completion of the Merger, our pre‑existing stockholders and former Bats stockholders would own approximately 72% and 28% of the outstanding shares of our common stock, respectively. The Merger will have no effect on the number of shares of our common stock owned by our existing stockholders.

NOTE 67 — 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 February 19, 2016, the Company granted 170,081 restricted stock units ("RSUs"), each of which entitles the ~~holders~~holder to one share of common stock upon vesting, to certain officers and employees at a fair value of $61.80 per share. The RSUs vest ratably over three years, with one-third vesting on each anniversary of the grant date, and vesting accelerates upon the occurrence of a change in control. Unvested RSUs will be forfeited if the officer or employee leaves the Company prior to the applicable vesting date, except in limited circumstances. The RSUs have no voting rights but entitle the holder to receive dividend equivalents.

In addition, on February 19, 2016, the Company granted 49,238 RSUs contingent on the achievement of performance conditions, including 24,619 RSUs, at a fair value of $61.80 per RSU, related to earnings per share during the performance period and 24,619 RSUs, at a fair value of $83.00 per RSU, related to total shareholder return during the performance period. The Company used the Monte Carlo valuation model method to estimate the fair value of the total shareholder return RSUs which incorporated the following assumptions: risk-free interest rate (0.90%), three-year volatility (21.1%) and three-year correlation with S&P 500 Index (0.41). Each of these performance shares has a performance condition under which the number of units ultimately awarded will vary from 0% to 200% of the original grant, with each unit representing the contingent right to receive one share of our common stock. The vesting period for the RSUs contingent on the achievement of performance is three years. For each of the performance awards, the RSUs will be settled in shares of our common stock following vesting of the RSU assuming that the participant has been continuously employed during the vesting period, subject to acceleration in the event of a change in control of the Company or in the event of a participant’s earlier death or disability. Participants have no voting rights with respect to RSUs until the issuance of the shares of stock. Dividends are accrued by the Company and will be paid once the RSUs contingent on the achievement of performance conditions vest.

On May 19, 2016, the Company granted 20,553 shares of stock, at a fair value of $63.29 per share, to the non-employee members of the board of directors. The shares have a one-year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. Unvested portions of the stock will be forfeited if the director leaves the company prior to the applicable vesting date.

For the three and ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, the Company recognized $~~3.7~~3.8 million and $~~3.1~~3.2 million and ~~$7.1~~$10.9 million and ~~$5.8~~$9.0 million in stock-based compensation expense, respectively. The three and ~~six~~nine months ended ~~June~~September 30, 2016 included ~~$0.3~~$0.2 million and ~~$0.5~~$0.7 million of accelerated stock-based compensation expense, respectively, for certain officers and employees as a result of attaining certain age and service based requirements in our long-term incentive plan and award agreements. Stock-based compensation expense is included in compensation and benefits in the condensed consolidated statements of income.

As of ~~June~~September 30, 2016, the Company had unrecognized stock-based compensation of $~~25.3~~18.2 million. The remaining unrecognized stock-based compensation is expected to be recognized over a weighted average period of ~~26.8~~23.1 months.

The activity in the Company’s restricted stock and restricted stock units for the ~~six~~nine months ended ~~June~~September 30, 2016 was as follows:

The carrying amount of our equity method investments totaled $13.0 million and $12.2 million as of ~~June~~September 30, 2016 and December 31, 2015, respectively, and is included in ~~Investments~~investments in our ~~Condensed Consolidated Balance Sheet.~~condensed consolidated balance sheet. Our equity method investments include our investments in Signal Trading Systems, LLC ("Signal") and CBOE Stock Exchange, LLC ("CBSX").

In May 2010, CBOE acquired a 50% interest in Signal from FlexTrade Systems, Inc. ("FlexTrade"). The joint venture develops and markets a multi-asset front-end order entry system, known as "Pulse," which has a particular emphasis on options trading. The Company assists in the development of the terminals and provides marketing services to the joint venture, which is accounted for under the equity method. We account for the investment in Signal under the equity method due to the substantive participating rights provided to the other limited liability company member, FlexTrade. In the ~~six~~nine months ended ~~June~~September 30, 2016, the Company recorded contributions to Signal of ~~$1.0~~$1.4 million and equity earnings in Signal of ~~$0.5~~$0.8 million. Additionally, the Company received a distribution of $0.5 million which reduced the carrying value of our investment.

The Company currently holds a 49.96% equity interest in CBSX in return for non-cash property contributions. CBSX ceased trading operations on April 30, 2014. CBOE is responsible for the compliance and regulation of the CBSX marketplace. In addition, the Company has a services agreement under which it provides CBSX with financial, accounting and technology support.

Cost ~~method~~Method

The carrying amount of our cost method investments totaled $60.5 million and $36.2 million as of ~~June~~September 30, 2016 and December 31, 2015, respectively, and is included in ~~Investments~~investments in our ~~Condensed Consolidated Balance Sheet.~~condensed consolidated balance sheet. We account for investments under the cost-method primarily as a result of our inability to exercise significant influence. As of ~~June~~September 30, 2016, our cost method investments primarily reflect our 20% investment in OCC and minority investments in American Financial Exchange ("AFX"), CurveGlobal and Eris Exchange Holdings, LLC ("Eris").

As previously reported in our Annual Report on Form 10-K for the year ended December 31, 2015, the SEC approved OCC’s rule change implementing OCC's new capital plan on February 11, 2016. Certain petitioners subsequently appealed the SEC approval order for the OCC capital plan to the U.S. Court of Appeals for the D.C. Circuit and moved to stay the SEC approval order. On February 23, 2016, the Court denied the petitioners’ motion to stay. The appeal of the SEC approval order remains pending.

In 2015, CBOE Holdings, through its subsidiary Loan Markets, LLC, acquired a minority interest in AFX, an electronic marketplace for small and mid-sized banks to lend and borrow short-term funds.

In January 2016, CBOE Holdings, through its subsidiary CBOE III, LLC, acquired a minority interest in CurveGlobal, a new interest rate derivatives venture.

In May 2016, CBOE Holdings, through its subsidiary CBOE III, LLC, acquired a minority interest in Eris, the parent of a U.S. based futures exchange group.

(1) Liquidity providers are eligible to participate in the sliding scale program, which involves prepayment of transaction fees, and receive reduced fees based on the achievement of certain volume thresholds within a calendar month. The prepayment of 2016 transaction fees totaled $11.4 million. This amount is amortized and recorded ratably, as transaction fees, over the respective twelve month period.

NOTE 1112 — 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). In addition, eligible employees may participate in the Supplemental Employee Retirement Plan, Executive Retirement Plan and Deferred Compensation Plan. Each plan is a defined contribution plan that is non-qualified under Internal Revenue Code. The Company contributed ~~$2.7~~$4.2 million and ~~$2.2~~$3.4 million to the defined contribution plans for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively.

The Company has a post-retirement medical plan for former members of senior management. The Company recorded immaterial post-retirement benefits expense for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015.

NOTE 1213 — INCOME TAXES

Income tax provision includes United States federal, state and local taxes and is based on reported pre-tax income. For the three and ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, the Company recorded income tax provisions of ~~$32.9~~$26.9 million and ~~$64.2~~$91.1 million and ~~$28.8~~$33.9 million and ~~$55.8~~$89.7 million, respectively. For the three months ended ~~June~~September 30, 2016 and 2015, the effective tax rate was ~~39.2%~~39.9% and ~~39.1%~~33.4%, respectively. The effective tax rate for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 was ~~39.1%~~39.3% and ~~39.0%~~36.7%, respectively. The higher effective rate in 2016 is primarily due to a net increase in unrecognized tax benefits compared to a net decrease for the same period in 2015.

Income tax expense is provided on an interim basis based upon our estimate of the annual effective income tax rate, adjusted each quarter for discrete items. In determining the estimated annual effective income tax rate, we analyze various factors, including projections of our annual earnings and taxing jurisdictions in which the earnings will be generated, the impact of state and local income taxes, and our ability to use tax credits.

As of ~~June~~September 30, 2016 and December 31, 2015, the Company had ~~$32.9~~$37.3 million and $31.9 million, in unrecognized tax benefits, respectively, all of which would favorably impact the effective tax rate if recognized. As of ~~June~~September 30, 2016 and December 31, 2015, the Company has recognized a liability for interest and penalties of ~~$9.2~~$10.3 million and $7.7 million, respectively.

We file income tax returns in the U.S. federal jurisdiction and various state jurisdictions. Federal income tax returns are generally not subject to examination by the Internal Revenue Service ("IRS") for tax years prior to ~~2008.~~2010. Tax years open to examination by state and local taxing authorities vary by jurisdiction. We are generally not subject to state or local tax examinations for tax years prior to 2007. The IRS is currently examining tax years 2008 through 2013. The New York State Department of Taxation and Finance is currently examining the returns filed for tax years 2007 through 2012. Tax returns for

tax years 2010 through 2012 are currently under examination by the New Jersey Division of Taxation. We have been notified by the Illinois Department of Revenue that it intends to examine our tax returns filed for the 2013 and 2014 tax years.

NOTE 1314 — FAIR VALUE MEASUREMENTS

Fair value is the price that would be received upon the sale of an asset or paid upon the 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, 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 non-financial 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 ~~June~~September 30, 2016 and December 31, 2015. The Company holds no financial liabilities that are measured at fair value on a recurring basis.

In 2015, CBOE Holdings, through its subsidiary Loan Markets, LLC, acquired a minority interest in AFX. 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.

In January 2016, CBOE Holdings, through its subsidiary CBOE III, LLC, acquired a minority interest in CurveGlobal. 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.

In May 2016, CBOE Holdings, through its subsidiary CBOE III, LLC, acquired a minority interest in Eris. 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.

The Company ~~has~~ recorded contingent consideration of $3.4 million through June 30, 2016, categorized as level 3, which iswas based on management's estimate of the achievement by Livevol of certain performance targets at nine and eighteen months

from the acquisition date. ~~If Livevol were to exceed management's estimates it could result~~In September 2016, the company settled the contingent consideration for $2.0 million resulting in ~~an additional payment~~a gain of $1.4 million which is recorded in ~~excess of the recorded contingent consideration.~~other income.

NOTE 1415 — LEGAL PROCEEDINGS

As of ~~June~~September 30, 2016, the end of the period covered by this report, the Company was subject to various legal proceedings and claims, 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. For a description of each of these proceedings, please see Note 12 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015.

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.

As of ~~June~~September 30, 2016, the Company does not believe 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.

The following information updates the legal proceedings disclosures in our Annual Report on Form 10-K for the year ended December 31, 2015 and subsequent Quarterly Reports on Form 10-Q.

~~ISE -- '707~~Lanier Litigation

On ~~November 22, 2006, International Securities Exchange, LLC ("ISE") filed an action~~May 23, 2014, Harold R. Lanier sued 14 securities exchanges, including CBOE, in the United States District Court for the Southern District of New York ~~claiming that CBOE's Hybrid trading system infringes ISE's U.S. Patent No. 6,618,707~~ (the ~~"'707 patent"~~"Court")~~. On January 31, 2007, CBOE filed an action in federal court~~ on behalf of himself and a putative class consisting of all persons in the ~~Northern District of Illinois seeking a declaratory judgment~~United States who entered into contracts to receive market data through certain data plans at any time since May 19, 2008 to the present. The complaint alleged that the ~~'707 patent~~market data provided under the CQ Plan and CTA Plans was ~~not infringed, not valid and/or not enforceable against CBOE. The New York case was transferred~~inferior to the ~~federal court~~data that the exchanges provided to those that directly receive other data from the exchanges, which the plaintiffs alleged is a breach of their “subscriber contracts” and a violation of the exchanges’ obligations under the CQ and CTA Plans. The plaintiffs sought monetary and injunctive relief. On May 30, 2014, Mr. Lanier filed two additional suits in the ~~Northern District~~same Court, alleging substantially the same claims and requesting the same types of ~~Illinois on August 9, 2007.~~

relief against the exchanges who participate in the UTP and the OPRA data plans. CBOE was a defendant in each of these suits, while C2 was only a defendant in the suit regarding the OPRA Plan. On ~~March 14, 2013, ISE conceded to an adverse judgment in this matter and asked that~~April 28, 2015, the Court dismissed Lanier’s complaint with prejudice because it was preempted by the federal ~~court~~regulatory scheme and because the claims were precluded by the terms of the applicable subscriber agreements.

Total operating revenues ~~increased~~decreased primarily due to ~~higher~~lower transaction fees ~~and exchange services and other~~partially offset by higher market data fees.

Total operating expenses increased primarily due to higher professional fees and outside services, partially offset by lower compensation and benefits, depreciation and amortization, and royalty fees. The increase in professional fees and outside services ~~and royalty fees.~~was mainly due to acquisition-related costs, which resulted in a lower operating margin for the quarter.

Recent Developments

The completion of the Merger is subject to certain conditions, including, among others, (i) adoption by Bats stockholders of the Merger Agreement, (ii) approval by CBOE Holdings stockholders of the issuance of CBOE Holdings common stock in connection with the Merger, (iii) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and regulatory approval by the SEC, Financial Industry Regulatory Authority ("FINRA") and the U.K. Financial Conduct Authority and (iv) other customary closing conditions. Bats' and CBOE Holdings' directors and officers have signed supportive voting agreements. The Merger is expected to close in the first half of 2017.

Operating Revenues

Total operating revenues for the three months ended ~~June~~September 30, 2016 were $~~163.3~~156.2 million, ~~an increase~~a decrease of $~~14.6~~30.8 million, or ~~9.8%~~16.5%, compared with the same period in 2015. The following summarizes changes in total operating revenues for the three months ended ~~June~~September 30, 2016 compared to the same period in 2015.

Transaction Fees

Transaction fees totaled $~~117.9~~111.9 million for the three months ended ~~June~~September 30, 2016, compared with $~~101.6~~144.8 million for the same period in 2015, ~~an increase~~a decrease of ~~$16.3~~$32.9 million, or ~~16.1%~~22.7%. The ~~increase~~decrease in transaction fees was primarily due to ~~an increase~~decreases in average revenue per contract of ~~9.9%~~12.4% and ~~a 5.6% increase~~11.8% in total trading volume. The ~~increase~~decrease in average revenue per contract resulted primarily from a shift in the mix of products traded. As a percentage of total trading volume, index options and futures contracts, which generate our highest options and overall average revenue per contract, respectively, accounted for ~~42.9%~~40.7% of trading volume during the ~~second~~third quarter of 2016 updown from ~~37.2%~~44.6% in the ~~second~~third quarter of 2015.

Average revenue per contract, discussed in more detail below, is impacted by our fee structures, which includes volume based incentive programs, mix of products traded, the account type (customer, firm, market-maker, etc.) and the manner in which a trade is executed. 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, which may be based on factors outside our control, but we can attempt to price our products at levels that are competitive in our market.

Trading volume is impacted by many factors, including: macroeconomic events, market volatility, regulatory actions or considerations, availability of capital, competition and pricing.

The following summarizes transaction fees by product category for the three months ended ~~June~~September 30, 2016 compared to the same period in 2015.

Factors contributing to the change in total average revenue per contract for the three months ended ~~June~~September 30, 2016 compared to the same period in 2015 include:

Volume Mix — We experienced a shift in the mix of products traded. As a percentage of total volume, index options and futures contracts accounted for ~~42.9%~~40.7% of total trading volume, updown from ~~37.2%~~44.6% in the prior year period. Index options and futures contracts represent our highest options average revenue per contract and highest average revenue per contract, respectively.

Rate structure — Our rate structure includes sliding scales, volume discounts, volume incentive programs and caps on fees as part of our effort to increase liquidity and market share in multiply-listed options (equities and exchange-traded products). The decrease in average revenue per contract in multiply-listed options was primarily a result of higher volume discounts and incentives.

Exchange Services and Other Fees

Exchange services and other fees for the three months ended ~~June~~September 30, 2016 increased ~~$1.6~~$0.6 million to ~~$11.3~~$11.6 million from ~~$9.7~~$11.0 million for the same period in 2015. The increase was primarily a result of revenue generated from Livevol technology services, which was acquired on August 7, 2015 and higher fees for technology services.

Market Data Fees

Market data fees for the three months ended ~~June~~September 30, 2016 increased to $8.2 million from ~~$7.6~~$7.1 million for the same period in 2015. For the three months ended ~~June~~September 30, 2016 and 2015, income derived from our market data services, which provide current and historical options and futures data, totaled ~~$4.4~~$4.3 million and ~~$4.0~~$3.8 million, respectively. OPRA income, which is allocated based on each exchange's share of total cleared options transactions, totaled ~~$3.8~~$3.9 million and ~~$3.6~~$3.3 million, respectively. The Company’s share of total cleared options transactions increased to ~~25.9%~~25.5% from ~~23.9%~~22.7% for the same period in 2015.

~~Other Revenue~~Regulatory Fees

~~Other revenue~~Regulatory fees for the three months ended~~June~~ September 30, 2016 and 2015 ~~was $3.5~~ were $9.1 million and ~~$7.7~~$8.2 million, respectively. The ~~decrease~~increase in regulatory fees is primarily the result of ~~$4.2 million was primarily due to lower revenue~~an increase in our options regulatory fees resulting from ~~fines assessed for rule violations.~~increased costs associated with the regulation of CBOE and C2.

Concentration of Revenue

All contracts traded on our exchanges must be cleared through clearing members of OCC. At ~~June~~September 30, 2016, there were one hundred ~~six~~five Trading Permit Holders that are clearing members of the OCC. Two clearing members accounted for 41% of transaction and other fees collected through the OCC for the three months ended ~~June~~September 30, 2016. The next largest clearing member accounted for approximately 14% of transaction and other fees collected through the OCC. No one

Trading Permit Holder using the services of the top two clearing members represented more than ~~26%~~27% of transaction and other fees collected through the OCC, for the respective clearing member, in the three months ended ~~June~~September 30, 2016. Should a clearing member withdraw from CBOE, we believe the Trading Permit Holder portion of that clearing member's trading activity would likely transfer to another clearing member.

The two largest clearing members 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 clearing members were to withdraw from the business of market-maker clearing and market-makers were unable to transfer to another clearing member, this could create significant disruption to the U.S. options markets, including ours.

Operating Expenses

Total operating expenses increased $~~10.0~~4.7 million, or ~~13.3%~~5.4%, to $~~85.3~~90.6 million for the three months ended ~~June~~September 30, 2016 from $~~75.3~~85.9 million for the same period in 2015. This increase was primarily due to higher professional fees and outside services, partially offset by lower compensation and benefits, depreciation and amortization, ~~professional fees and outside services~~ and royalty fees.

The following summarizes changes in operating expenses for the three months ended ~~June~~September 30, 2016 compared to the same period in 2015.

Compensation and Benefits

For the three months ended ~~June~~September 30, 2016, compensation and benefits were $~~28.5~~28.4 million, or ~~17.5%~~18.1% of total operating revenues, compared with $~~24.1~~29.6 million, or ~~16.2%~~15.8% of total operating revenues, for the same period in 2015. This represented ~~an increase~~a decrease of $~~4.4~~1.2 million, or ~~18.2%~~4.2%, from the prior period, which primarily resulted from ~~increased staffing levels and higher~~lower annual incentive compensation, which is aligned with our financial performance relative to our ~~targets.~~targets, partially offset by increased staffing levels and higher stock-based compensation, including accelerated stock-based compensation expense.

Depreciation and Amortization

For the three months ended ~~June~~September 30, 2016, depreciation and amortization costs were $~~12.3~~10.2 million compared with $~~11.3~~12.4 million for the same period in 2015. This represented ~~an increase~~a decrease of $~~1.0~~2.2 million, which ~~primarily resulted from increased capital spending for systems,~~was due to the ~~acceleration~~final write-off at June 30, 2016 of ~~depreciation for~~ certain assets that ~~have~~had a shorter than expected useful life, ~~and~~partially offset by the amortization of intangible assets related to the acquisitions of Livevol and Vest.

Professional Fees and Outside Services

Professional fees and outside services for the three months ended ~~June~~September 30, 2016 were ~~$14.7~~$21.4 million compared with $12.6 million for the same period in 2015, an increase of $~~2.1~~8.8 million, which primarily resulted from higher legal and professional fees, ~~including~~mainly acquisition-related costs, and higher contract services related to certain regulatory services provided by FINRA for CBOE and C2.

Royalty Fees

Royalty fees for the three months ended ~~June~~September 30, 2016 were $~~19.3~~19.4 million compared with $~~16.8~~21.8 million for the same period in 2015. This represented ~~an increase~~a decrease of $~~2.5~~2.4 million, which primarily resulted from ~~higher~~lower trading volume in licensed products.

Operating Income

As a result of the items above, operating income for the three months ended ~~June~~September 30, 2016 was $~~78.0~~65.6 million compared to $~~73.4~~101.1 million for the same period in 2015, ~~an increase~~a decrease of $~~4.6~~35.5 million.

Other Income

Other income reflected income of ~~$5.8~~$1.7 million for the three months ended ~~June~~September 30, 2016 compared with income of $0.3 million for the same period in 2015. The increase in other income resulted from ~~$5.5 million of proceeds received from the~~a gain on settlement of ~~litigation.~~contingent consideration related to the acquisition of Livevol.

Income before Income Taxes

Income before income taxes for the three months ended ~~June~~September 30, 2016 was $~~83.8~~67.3 million compared to $~~73.7~~101.4 million for the same period in 2015, ~~an increase~~a decrease of $~~10.1~~34.1 million.

Income Tax Provision

For the three months ended ~~June~~September 30, 2016, the income tax provision was $~~32.9~~26.9 million compared to $~~28.8~~33.9 million for the same period in 2015. The effective tax rate was ~~39.2%~~39.9% and ~~39.1%~~33.4% for the three months ended ~~June~~September 30, 2016 and 2015, respectively. In the third quarter of 2015, the Company considered its tax positions relative to research and development credits claimed for tax years ended 2008 through 2013 to have been effectively settled and therefore recognized the related tax benefit. In the third quarter of 2016, the Company determined that the likelihood of the taxing authority reexamining that tax position is no longer remote. Consequently, the Company no longer considers its 2008-2013 research and development tax credit positions to be effectively settled and therefore recorded a related increase in unrecognized tax benefits during the third quarter of 2016.

Net Income

As a result of the items above, net income allocated to common stockholders for the three months ended ~~June~~September 30, 2016 was $~~50.7~~40.3 million compared to $~~44.6~~67.2 million for the same period in 2015, ~~an increase~~a decrease of $~~6.1~~26.9 million. Basic and diluted net income per share allocated to common stockholders were $~~0.62~~0.50 and $~~0.54~~0.81 for the three months ended ~~June~~September 30, 2016 and 2015, respectively.

Total operating revenues increased primarily due to higher transaction fees, exchange ~~fees~~services and other ~~services,~~fees, market data fees and regulatory fees, partially offset by lower other revenue.

Total operating expenses increased primarily due to higher compensation and benefits, ~~depreciation and amortization,~~ professional fees and outside services and royalty fees. The increase in professional fees and outside services was mainly due to acquisition-related costs, which resulted in a lower operating margin for the period.

Operating Revenues

Total operating revenues for the ~~six~~nine months ended ~~June~~September 30, 2016 were ~~$325.7~~$481.9 million, an increase of ~~$34.2~~$3.3 million, or ~~11.7%~~0.7%, compared with the same period in 2015.

Transaction Fees

Transaction fees totaled $~~235.9~~347.9 million for the ~~six~~nine months ended ~~June~~September 30, 2016, compared with $~~200.3~~345.2 million for the same period in 2015, an increase of ~~$35.6~~$2.7 million, or ~~17.8%~~0.8%. This increase was primarily due to a ~~14.6%~~3.5% increase in average revenue per contract, ~~and~~partially offset by a ~~2.8% increase~~2.6% decrease in total trading volume. The increase in average revenue per contract resulted primarily from a shift in ~~volume~~ mix of products traded. As a percent of total trading volume, index options and futures contracts, which generates our highest options and overall average revenue per contract, respectively, accounted for ~~42.6%~~42.0% of trading volume during the ~~six~~nine months ended ~~June~~September 30, 2016 up from ~~35.2%~~38.7% during the same period in 2015.

Factors contributing to the change in total average revenue per contract for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to the same period in 2015, include:

Product mix — Average revenue per contract reflects a shift in the mix of products traded. Index options and futures accounted for ~~42.6%~~42.0% of total trading volume as compared to ~~35.2%~~38.7% in the prior year period.

Rate structure — The decrease in average revenue per contract in multiply-listed options was primarily the result of higher volume discounts and incentives.

Exchange Services and Other Fees

Exchange services and other fees for the ~~six~~nine months ended ~~June~~September 30, 2016 increased to $~~22.8~~34.3 million from $~~19.5~~30.5 million for the same period in 2015. The increase was primarily a result of revenue generated from Livevol technology services, which was acquired in August 2015, and higher fees for technology services.

Market Data Fees

Market data fees for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 totaled $~~16.1~~24.4 million and ~~$15.6~~$22.7 million, respectively. Income derived from our market data services totaled ~~$8.7~~$13.0 million and ~~$8.2~~$12.0 million, respectively. The increase of ~~$0.5~~$1.0 million resulted primarily from increases in subscribers and fees for certain market data services. OPRA income totaled ~~$7.4~~$11.4 million and $10.7 million for the ~~periods~~nine months ended ~~June~~September 30, 2016 and ~~2015.~~2015, respectively. The Company’s share of income derived from OPRA ~~decreased to~~was ~~23.3%~~ ~~from~~ ~~24.6%~~24.0% for the ~~same period in~~ ~~2015. The decrease in share was offset by an increase in total OPRA distributable income resulting from a membership fee from a new exchange that joined OPRA~~nine months ended 2016 and ~~fee increases implemented by OPRA resulting in comparable income in the periods presented.~~2015.

Regulatory Fees

Regulatory fees for the ~~six~~nine months ended ~~June~~September 30, 2016 increased to $~~18.3~~27.4 million from $~~17.1~~25.3 million for the same period in 2015. The increase in regulatory fees is primarily the result of an increase in our options regulatory fees resulting from increased costs associated with the regulation of CBOE and ~~C2, partially offset by a decrease in regulatory fees received for other regulatory services.~~C2.

Other Revenue

Other revenue for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 were ~~$6.1~~$8.5 million and ~~$12.0~~$14.8 million, respectively. The decrease of ~~$5.9~~$6.3 million was primarily due to lower revenue from fines assessed for rule violations.

Operating Expenses

Total operating expenses were ~~$168.2~~$258.8 million and ~~$148.6~~$234.6 million for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. This increase was primarily due to higher compensation and benefits, ~~depreciation and amortization,~~ professional fees and outside services and royalty fees. As a percentage of operating revenues for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, operating expenses were ~~51.7%~~53.7% and ~~51.0%~~49.0%, respectively.

The following summarizes changes in operating expenses for the ~~six~~nine months ended ~~June~~September 30, 2016 compared to the same period in 2015.

Compensation and Benefits

For the ~~six~~nine months ended ~~June~~September 30, 2016, compensation and benefits were $~~55.6~~84.0 million, or ~~17.1%~~17.4% of total operating revenues, compared with $~~49.6~~79.2 million, or ~~17.0%~~16.5% of total operating revenues, for the same period in 2015. This represented an increase of ~~$6.0~~$4.8 million, which primarily resulted from increased staffing levels, higher stock-based compensation, including accelerated stock-based compensation expense, ~~and higher annual incentive compensation, which is aligned with our financial performance relative to our targets. These amounts were~~ partially offset by lower medical insurance expenses.

~~Depreciation and Amortization~~

~~For the~~ ~~six months endedJune 30, 2016, depreciation and amortization costs were $24.1 million compared with $21.7 million for the same period in~~ ~~2015~~. This represented an increase of $2.4 million, which primarily resulted from increased capital spending for systems, the acceleration of depreciation for certain assets that have a shorter than expected useful life and amortization of intangible assets related to the acquisitions of Livevol and Vest.

Professional Fees and Outside Services

Expenses related to professional fees and outside services increased to ~~$28.4~~$49.8 million for the ~~six~~nine months ended ~~June~~September 30, 2016 from ~~$24.5~~$37.2 million in the prior-year period. This represented an increase of ~~$3.9~~$12.6 million, which primarily resulted from higher legal and professional fees, ~~including~~mainly acquisition related costs, and contract services related to certain regulatory services provided by ~~FINRA and other professional fees.~~FINRA.

Royalty Fees

Royalty fees for the ~~six~~nine months ended ~~June~~September 30, 2016 were ~~$38.5~~$57.8 million compared with ~~$30.9~~$52.7 million in the prior-year period. This represented an increase of ~~$7.6~~$5.1 million which primarily resulted from higher trading volume in licensed products.

Operating Income

As a result of the items above, operating income for the ~~six~~nine months ended ~~June~~September 30, 2016 was ~~$157.5~~$223.1 million compared to ~~$142.9~~$244.0 million for the same period in 2015, ~~an increase~~a decrease of ~~$14.6~~$20.9 million.

Other Income/(Expense)

Other income/(expense) reflected income of ~~$6.8~~$8.5 million for the ~~six~~nine months ended ~~June~~September 30, 2016 compared with an immaterial expense for the same period in 2015. The income primarily included proceeds from the settlement of litigation, the Company's share of equity earnings of Signal, ~~and~~ the receipt of dividend income in the first quarter of 2016 in excess of the amount originally declared by the OCC in December ~~2015.~~2015 and a gain on the settlement of contingent consideration related to the acquisition of Livevol.

Income before Income Taxes

Income before income taxes for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015 was ~~$164.3~~$231.6 million and ~~$142.9~~$244.3 million, respectively, ~~an increase~~a decrease of ~~$21.4~~$12.7 million.

Income Tax Provision

For the ~~six~~nine months ended ~~June~~September 30, 2016, the income tax provision was $~~64.2~~91.1 million compared to $~~55.8~~89.7 million for the same period in 2015. The effective tax rate was ~~39.1%~~39.3% and ~~39.0%~~36.7% for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. In 2015, the Company recorded a benefit from the release of an uncertain tax position related to research and development credits, which we believed were effectively settled. In 2016, the company no longer considers certain positions to be effectively settled and therefore recorded a related increase in unrecognized tax benefits.

Net Income

As a result of the items above, net income allocated to common stockholders for the ~~six~~nine months ended ~~June~~September 30, 2016 was ~~$99.7~~$140.0 million compared to $~~86.7~~153.9 million for the same period in 2015, ~~an increase~~a decrease of ~~$13.0~~$13.9 million. Basic and diluted net income per share allocated to common stockholders were $~~1.22~~1.72 and $~~1.04~~1.85 for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively.

LIQUIDITY AND CAPITAL RESOURCES

As of ~~June~~September 30, 2016, the Company had $~~52.2~~72.8 million of cash and cash equivalents, a decrease from $102.3 million as of December 31, 2015. 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, capital expenditures, actual and anticipated quarterly dividends and, based on availability of cash, common stock repurchases under the announced program. We expect our cash on hand at ~~June~~September 30, 2016 and funds generated from operations to be sufficient to continue to meet our 2016 cash requirements. ~~From time~~

The Company will require significant capital in order to ~~time,~~complete its proposed acquisition of Bats. In connection with entering into the Merger Agreement, we ~~consider~~entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or any of its designated affiliates) (Bank of America, N.A., and other such financial institutions that accede as lender to such debt commitment letter in accordance with its terms are referred to herein as the ~~possibility~~“Lenders”), which provides that, subject to the satisfaction and waiver of ~~acquisitions, dispositions~~certain conditions which are usual and ~~strategic alliances that we believe would strengthen our business~~customary for financing of this type, the Lenders are committed to provide debt financing for the purposes of funding (i) the cash consideration to be paid in the ~~long-term; however, if consummated these~~ transactions ~~may negatively impact our liquidity~~contemplated by the Merger Agreement, (ii) the refinancing of certain existing indebtedness of Bats and its subsidiaries and (iii) related fees and expenses, which debt financing consists of a senior unsecured 364-day bridge loan facility in an aggregate principal amount of up to $1.65 billion to the extent CBOE Holdings fails to generate gross cash proceeds in an aggregate principal amount of up to $1.65 billion from permanent financing including in the ~~short-term.~~form of a senior unsecured term loan facility and the issuance of senior unsecured notes on or prior to the consummation of the transaction contemplated by the Merger Agreement. On September 26, 2016, the Company paid commitment and structuring fees of $5.0 million that will be amortized over the period prior to the closing of the transaction that is expected to occur in the first half of 2017.

In addition to requiring significant capital in order to complete the Company's proposed acquisition of Bats, shares of CBOE Holdings common stock are to be issued upon conversion of shares of Bats common stock in the Merger. Based on the number of shares of our common stock and Bats common stock outstanding on September 23, 2016, immediately following the completion of the Merger, our pre‑existing stockholders and former Bats stockholders would own approximately 72% and 28% of the outstanding shares of our common stock, respectively. The Merger will have no effect on the number of shares of our common stock owned by our existing stockholders.

Cash Flows

Operating Activities

Net cash flows provided by operating activities totaled ~~$114.9~~$174.1 million and ~~$105.8~~$194.1 million for the ~~six~~nine months ended~~June~~ September 30, 2016 and 2015, respectively. The ~~increase~~decrease in net cash flows provided by operating activities was primarily due to ~~higher~~lower net income.

Investing Activities

Net cash flows used in investing activities totaled $~~63.8~~77.3 million and $~~48.3~~62.6 million for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. The net cash flows used in investing activities primarily represented our majority investment in Vest, which totaled $14.3 million, and other investments totaling ~~$23.7~~$24.2 million, which includes our investments in CurveGlobal and Eris. Expenditures for capital and other assets totaled $~~25.4~~36.4 million and $~~17.6~~26.9 million for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively, primarily representing costs associated with systems hardware and software development.

Financing Activities

Net cash flows used in financing activities totaled $~~101.1~~126.3 million and $~~115.8~~157.7 million for the ~~six~~nine months ended ~~June~~September 30, 2016 and 2015, respectively. The $~~14.7~~31.4 million decrease in net cash flows used in financing activities was primarily due to lower stock repurchases.

Dividends

The Company’s expectation is to continue to pay dividends. 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 debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends.

Share Repurchase Program

In 2011, the board of directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and approved additional authorizations of $100 million in each of 2012, 2013, 2014, 2015, and February 2016 for a total authorization of $600 million. 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.

As of September 30, 2016, the Company had $97.0 million of availability remaining under its existing share repurchase authorizations. We were not active in our share repurchase program during the third quarter.

Under the program, for the ~~six~~nine months ended ~~June~~September 30, 2016, the Company repurchased 947,786 shares of common stock at an average cost per share of $63.83, totaling $60.5 million.

Since inception of the program through ~~June~~September 30, 2016, the Company has repurchased 10,947,401 shares of common stock at an average cost per share of $45.95, totaling $503.0 million.

~~As of June 30, 2016, the Company had $97.0 million of availability remaining under its existing share repurchase authorizations.~~

Contractual Obligations

As of ~~June~~September 30, 2016, there have been no material changes to our lease and contractual obligations presented in our Annual Report on Form 10-K for the year ended December 31, 2015.

If the Merger Agreement is terminated under certain specified circumstances, CBOE Holdings may be required to pay Bats a termination fee of $110 million and/or reimburse Bats’ expenses up to $10 million under the Merger Agreement.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

(the “Subsequent Merger”), with Merger LLC surviving the Subsequent Merger as a wholly-owned subsidiary of CBOE Holdings. Investors should consider the following risk factors relating to the Merger.

Other than the risk ~~factor~~factors listed 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 for the year ended December 31, 2015 and subsequent Quarterly Reports on Form 10-Q.

Risks Relating to the Merger

~~Legislative~~Failure to complete the proposed Merger within the expected timeframe or at all could have a material adverse impact on our business, financial condition and results of operations.

There can be no assurance that the Merger will occur. The closing of the Merger is subject to certain conditions, including, among others, (i) the adoption of the Merger Agreement by the holders of at least a majority of the outstanding shares of Bats common stock entitled to vote thereon, (ii) approval of the issuance of shares of our common stock in the Merger by the holders of at least a majority of the shares of our common stock entitled to vote thereon and present in person or represented by proxy at the meeting of our stockholders called for such purpose, (iii) the expiration or earlier termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and regulatory approval by the SEC, Financial Industry Regulatory Authority and the U.K. Financial Conduct Authority, (iv) no court order or other legal restraint or prohibition preventing the consummation of the Merger or the Subsequent Merger or imposing a “burdensome effect” (as defined in the Merger Agreement) upon the consummation thereof, (v) the absence of any pending action commenced by a governmental or regulatory body wherein a judgment would reasonably be expected to prevent the consummation of the Merger or the Subsequent Merger or impose a burdensome effect upon the consummation thereof, (vi) receipt of tax opinions from counsel to each of us and Bats with respect to the treatment of the Merger and Subsequent Merger

from a tax perspective, (vii) in the case of our obligation to effect the Merger, no exercise of appraisal rights by Bats stockholders holding more than 20% of the outstanding shares of Bats common stock, (viii) in the case of each party’s obligation to effect the Merger, the absence of a material adverse effect with respect to the other party since the date of the Merger Agreement and (ix) subject to materiality exceptions, the accuracy of the representations and warranties made by us, Merger Sub and Merger LLC, on the one hand, and Bats, on the other hand, and compliance by us, Merger Sub, Merger LLC and Bats in all material respects with our and their respective obligations under the Merger Agreement. There can be no assurance that the conditions to the closing of the Merger will be satisfied in a timely matter or at all.

In particular, before the proposed transactions contemplated by the Merger Agreement, including the Merger, may be completed, various clearances and approvals must be obtained from certain regulatory and governmental authorities. These regulatory and governmental entities may impose conditions on the granting of such approvals. Such conditions and the process of obtaining regulatory approvals could have the effect of delaying completion of the Merger or of imposing additional costs or limitations on the combined company following the Merger. The regulatory approvals may not be received at all, may not be received in a timely fashion and may contain conditions on the completion of the Merger. However, if any such conditions impose a “burdensome effect” as defined in the Merger Agreement, the parties may not be obligated to complete the Merger, and either Bats or we may have the right to terminate the Merger Agreement. In addition, our and Bats’ obligations to complete the Merger are conditioned on the receipt of certain regulatory approvals or waiver by the other party of such condition.

Failure to complete the Merger could negatively impact our stock price and future businesses and financial results.

If the Merger is not completed, our ongoing business may be adversely affected, and we will be subject to several risks and consequences, including the following:

we may be required, under certain circumstances, to pay Bats a termination fee of $110 million or reimburse Bats’ expenses up to $10 million under the Merger Agreement;

we will be required to pay certain costs relating to the Merger, whether or not the Merger is completed, such as legal, accounting, financial advisory and printing fees;

under the Merger Agreement, we are subject to certain restrictions on the conduct of our business prior to completing the Merger that may adversely affect our ability to execute certain of our business strategies; and

matters relating to the Merger may require substantial commitments of time and resources by our management, which could otherwise have been devoted to other opportunities that may have been beneficial to us as an independent company and such commitments may impact future earnings of the combined company.

In addition, if the Merger is not completed, we may experience negative reactions from the financial markets and from our customers and employees. We also could be subject to litigation related to any failure to complete the Merger or to enforcement proceedings commenced against us to perform our obligations under the Merger Agreement. If the Merger is not completed, we cannot assure our stockholders that the risks described above will not materialize and will not materially adversely affect our business, financial results and stock prices.

The announcement and pendency of the Merger may adversely affect our business, financial condition and results of operations.

Uncertainty about the effect of the Merger on our employees, customers, and other parties may have an adverse effect on our business, financial condition and results of operation regardless of whether the Merger is completed. These risks to our business include the following, all of which could be exacerbated by a delay in the completion of the Merger:


▪	the impairment of our ability to attract, retain and motivate our employees, including key personnel;


▪	the diversion of significant management time and resources towards the completion of the Merger;


▪	difficulties maintaining relationships with customers and other business partners;


▪	delays or deferments of certain business decisions by our customers and other business partners;


▪	the inability to pursue alternative business opportunities or make appropriate changes to our business because of requirements in the Merger Agreement that we conduct our business in the ordinary course of business consistent with past practice and not engage in certain kinds of transactions prior to the completion of the Merger;


▪	litigation relating to the Merger and the costs related thereto; and


▪	the incurrence of significant costs, expenses and fees for professional services and other transaction costs in connection with the Merger.

If our financing for the Merger becomes unavailable, the Merger may not be completed.

We intend to finance all or a portion of the cash component of the Merger consideration with debt financing, which may include a senior unsecured 364-day bridge loan facility in an aggregate principal amount of up to $1.65 billion, or permanent financing including in the form of a senior unsecured term loan facility and the issuance of senior unsecured notes on or prior to effective time of the Merger. There are a number of conditions in the commitment letter (the “Debt Commitment Letter”) among us, Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated (or any of its designated affiliates) that must be satisfied or waived in order for closing of the debt financing to occur. There is a risk that these conditions will not be satisfied. In the event that the financing contemplated by the Debt Commitment Letter is not available, we may be required to obtain alternative financing on terms that are less favorable to us than those in the Debt Commitment Letter. In addition, any alternative financing may not be available on acceptable terms, in a timely manner or at all. While obtaining financing is not a condition to our obligation to effect the Merger under the Merger Agreement, if other financing becomes necessary and we are unable to secure such other financing, the Merger may not be completed.

We expect to incur substantial indebtedness to finance the Merger, which may decrease our business flexibility and adversely affect our financial results.

In addition to using cash on hand at CBOE Holdings and Bats, we expect to incur indebtedness of up to approximately $1.65 billion to finance a portion of the cash component of the Merger consideration, to refinance existing indebtedness of Bats and its subsidiaries and to pay related fees and expenses. Prior to entering into the Merger Agreement, we did not have any indebtedness and were not subject to any financial covenants. The financial and other covenants to which we have agreed or may agree to in connection with the incurrence of new indebtedness, and the combined company’s increased indebtedness may have the effect, among other things, of reducing the combined company’s flexibility to respond to changing business and economic conditions, thereby placing the combined company at a competitive disadvantage compared to competitors that have less indebtedness and making the combined company more vulnerable to general adverse economic and industry conditions. The combined company’s increased indebtedness will also increase borrowing costs, and the covenants pertaining thereto may also limit the combined company’s ability to repurchase shares of our common stock, increase dividends or obtain additional financing to fund working capital, capital expenditures, acquisitions or general corporate requirements. The combined company will also be required to dedicate a larger portion of its cash flow from operations to payments on its indebtedness, thereby reducing the availability of its cash flow for other purposes, including working capital, capital expenditures and general corporate purposes. In addition, the terms and conditions of such debt may not be favorable to the combined company and, as such, could further increase the costs of the Merger, as well as the overall burden of such debt upon the combined company and the combined company’s business flexibility. Further, if any portion of the combined company’s borrowings is at variable rates of interest, the combined company will be exposed to the risk of increased interest rates unless the combined company enters into offsetting hedging transactions.

The combined company’s ability to make payments on and to refinance its debt obligations and to fund planned capital expenditures will depend on its ability to generate cash from the combined company’s operations. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond the combined company’s control.

The combined company may not be able to refinance any of its indebtedness on commercially reasonable terms, or at all. If the combined company cannot service its indebtedness, the combined company may have to take actions such as selling assets, seeking additional equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances, any of which could impede the implementation of the combined company’s business strategy or prevent the combined company from entering into transactions that would otherwise benefit its business. Additionally, the combined company may not be able to effect such actions, if necessary, on commercially reasonable terms, or at all.

Any of the foregoing consequences could adversely affect the combined company’s financial results.

Deterioration in our credit profile will increase our costs of borrowing money.

We have received an investment grade credit rating from S&P Global Ratings (BBB+) and a provisional investment grade rating from Moody’s Investor Service (Baa1). (Ratings from credit agencies are not recommendations to buy, sell or hold our securities, and each rating should be evaluated independently of any other rating.) There is no assurance that we will maintain such credit ratings, since credit ratings may be lowered or withdrawn entirely by a rating agency if, in its judgment, the circumstances warrant. If a rating agency were to downgrade our rating below investment grade, our borrowing costs and the costs of the proposed transactions contemplated by the Merger Agreement would increase. Further, the provisional rating from Moody’s Investor Service is based on the assumption that the Merger will close in accordance with the terms of the

Merger Agreement. Upon the effective time of the Merger, the provisional rating will be converted to a definitive rating, subject to review of the final terms. There is no assurance that Moody’s Investor Service will assign the same rating to us following the Merger.

The Merger Agreement contains provisions that may discourage other companies from trying to acquire us.

The Merger Agreement contains provisions that apply both during the pendency of the Merger transaction with Bats as well as afterward should the Merger with Bats not be consummated that may discourage a third party from submitting a business combination proposal to us that might result in greater value to our stockholders than the Merger. These Merger Agreement provisions include a general prohibition on us from soliciting, or, subject to certain exceptions, entering into discussions with any third party regarding any acquisition proposal or offers for competing transactions. In addition, we may be required to pay Bats a $110 million termination fee and reimburse Bats for its expenses incurred in connection with the Merger in an aggregate amount not to exceed $10 million in certain circumstances involving acquisition proposals for competing transactions.

The price of our common stock might increase or decline prior to the completion of the Merger, which would change the value of the Merger consideration to be received by Bats stockholders pursuant to the Merger Agreement.

The market price of ourcommon stock at the time the Merger is completed may vary significantly from the price on the date of the Merger Agreement. On September 22, 2016, the last full trading day prior to media publications regarding the proposed Merger, ourcommon stock closed at $69.41 per share as reported on NASDAQ, and on September 23, 2016, the last full day of trading prior to the announcement of the Merger Agreement, our common stock closed at $70.30 per share as reported on NASDAQ. If the market price of our common stock increases above $70.30, the market value of the Merger consideration will be greater than $32.50 per share of Bats common stock. If the market price of our common stock decreases significantly prior to the Bats stockholder vote on the adoption of the Merger Agreement, it may be difficult to obtain Bats stockholder approval of any proposal to adopt the Merger Agreement.

The issuance of shares of our common stock to Bats stockholders pursuant to the Merger Agreement will substantially reduce the percentage ownership interests of our pre-existing stockholders.

Based on the number of shares of our common stock and Bats common stock outstanding on September 23, 2016, immediately following the completion of the Merger, our pre‑existing stockholders and former Bats stockholders would own approximately 72% and 28% of the outstanding shares of our common stock, respectively. The Merger will have no effect on the number of shares of our common stock owned by our existing stockholders. The issuance of shares of our common stock to Bats stockholders and holders of equity incentive awards will cause a significant reduction in the relative percentage interests of our current stockholders in earnings, voting, liquidation value and book and market value.

The Merger will result in changes ~~affecting~~to the ~~listed options~~board of directors and management of the combined company that may affect the strategy of the combined company as compared to our strategy as a standalone company.

If the parties complete the Merger, the composition of our board of directors and our management team will change from our current board and management team. The board of directors of the combined company will consist of 14 members, including three individuals designated by Bats who are serving as Bats directors immediately prior to the effective time of the Merger. We will also have executive officers from both us and Bats. This new composition of our board of directors and our management team may affect the business strategy and operating decisions of the combined company upon the completion of the Merger.

We will incur significant transaction and integration costs in connection with the Merger.

We and Bats expect to incur a number of costs associated with completing the Merger and integrating the operations of the two companies. The substantial majority of these costs will be non-recurring expenses resulting from the Merger and will consist of transaction costs related to the Merger, facilities and systems consolidation costs and employment‑related costs. Additional unanticipated costs may be incurred in the integration of our businesses with Bats’ businesses. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, will offset incremental transaction and Merger-related costs over time, this net benefit may not be achieved in the near term, or ~~futures markets~~at all.

We may not realize all of the anticipated benefits of the transactions contemplated by the Merger Agreement or such benefits may take longer to realize than expected.

The success of the Merger will depend, in part, on our ability to realize the anticipated benefits from combining our

businesses with Bats’ businesses. Our ability to realize the anticipated benefits of the Merger will depend, to a large extent, on our ability to integrate our businesses with Bats’ businesses. The combination of two independent companies is a complex, costly and time-consuming process. As a result, the combined company will be required to devote significant management attention and resources to integrating our business practices and operations with those of Bats. The integration process may disrupt the business of either or both of the companies and, if implemented ineffectively, could preclude realization of the full benefits expected by us. The failure of the combined company to meet the challenges involved in integrating successfully our operations with those of Bats or otherwise to realize the anticipated benefits of the proposed transactions could cause an interruption of, or a loss of momentum in, the activities of the combined company and could seriously harm its results of operations. In addition, the overall integration of the two companies may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of client relationships and diversion of management’s attention, and may cause the combined company’s stock price to decline. The difficulties of combining the operations of the companies include, among others:

unanticipated issues in integrating information technology, communications and other systems;

unforeseen expenses or delays associated with the integration or the Merger;

managing a significantly larger company;

the potential diversion of management focus and resources from other strategic opportunities and from operational matters, and potential disruption associated with the Merger;

maintaining employee morale and retaining key management and other key employees;

integrating two unique business cultures, which may prove to be incompatible;

the possibility of faulty assumptions underlying expectations regarding the integration process and expense synergies;

consolidating corporate and administrative infrastructures and eliminating duplicative operations;

coordinating geographically separate organizations;

changes in applicable laws and regulations;

managing costs or inefficiencies associated with integrating the operations of the combined company; and

making any necessary modifications to internal financial control standards to comply with the Sarbanes‑Oxley Act of 2002 and the rules and regulations promulgated thereunder.

Many of these factors will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy, which could materially impact our business, financial condition and results of operations. In addition, even if Bats’ and our operations are integrated successfully, we may not realize the full benefits of the proposed transactions, including the synergies, cost savings or growth opportunities that we expect. These benefits may not be achieved within the anticipated time frame, or at all. As a result, we cannot assure you that the combination of Bats with uswill result in the realization of the full benefits anticipated from the transactions contemplated by the Merger Agreement.

A failure to integrate successfully or a material disruption in information technology systems could adversely affect the combined company’s business and results of operations.

The combined company will rely extensively on its information technology systems. The failure of information technology systems to operate effectively, difficulty in integrating our information technology systems with Bats’ information technology systems, inconsistencies in standards, controls, procedures and policies and problems with transitioning to upgraded or replacement systems could adversely impact the business of the combined company. In addition, a number of our trading permit holders are not connected to Bats’ information technology platforms and must complete the process of connecting to these platforms as part of the integration.

The process of integrating information technology systems may take longer, cost more and provide fewer synergies than initially anticipated. There may also be new regulations adopted during the transition period that require systems changes, which could divert attention away from integration process and cause delays. To the extent this occurs, the benefits of the proposed transaction may be reduced or delayed or may never come to fruition. Although Bats has experience with transitioning other businesses to its information technology platform, there are certain portions of our business, such as open outcry trading and complex order trading, that have not yet been addressed by Bats’ information technology platform.

We currently expect to complete the integration of our information technology systems with those of Bats in phases over a four-year period following the Merger. However, we may not be able to successfully achieve the transition on the timetable currently contemplated, and the transition may not be successful or could encounter various difficulties and unexpected issues. Any delays or issues that we encounter in the transition could have a material adverse effect on ~~our business.~~

~~Changes in regulation by~~ the ~~SEC, CFTC, foreign regulators or other government action, including SEC approval~~businesses of ~~rule filings by other SROs or entities, including OCC,~~the combined company and could ~~materially~~negatively affect our ~~markets.~~reputation, which in turn could have a material adverse effect on the combined company’s overall business, results of operations and financial condition, as well as impair customer confidence in the combined company’s product offerings and overall services.

If the combined company is unable to manage its growth, its business and financial results could suffer.

The combined company’s future financial results will depend in part on its ability to manage its core businesses, including any growth that the combined company may be able to achieve. Over the past several years, weand Bats have each engaged in the identification of, and competition for, growth and expansion opportunities. In ~~recent years,~~order to achieve those initiatives, the ~~securities~~combined company will need to, among other things, recruit, train, retain and ~~futures industries have been subject~~effectively manage employees and expand its operations and financial control systems. If the combined company is unable to ~~significant regulatory changes as~~manage its businesses effectively and profitably, its business and financial results could suffer.

To be successful, the combined company must retain and motivate key employees, including those experienced with post-acquisition integration, and failure to do so could seriously harm the combined company.

The success of the combined company largely depends on the skills, experience and continued efforts of management and other key personnel. As a result, ~~of regulatory reforms in response~~ to be successful, the ~~global economic crisis.~~

~~In 2010, Congress passed the Dodd-Frank Act~~combined company must retain and motivate executives and other ~~legislation. While many~~key employees. In particular, the combined company expects to benefit from the integration experience of ~~its requirements~~certain Bats personnel. Certain key executives of Bats have ~~been implemented or are~~executed offer letters with us to continue their employment following the Merger. However, these executives will continue to be at‑will employees, and the offer letters provide no assurance that these executives will remain with the combined company. Additionally, certain of our information technology employees will be important to retain during the transition period to effectively manage our information technology platforms and to assist Bats in the process of ~~being implemented, some of~~integrating its information technology platform. If these personnel were to leave, the provisions in Dodd-Frank that impact our markets require additional action by the SEC or the CFTC. Depending on how the SEC and CFTC interpret and implement these laws, exchanges like ours could be subject tocombined company may experience increased ~~competition and additional costs. We could also see reduced trading by our customers due to increased margin or other requirements.~~

Under the Collins Amendment to the Dodd-Frank Act, starting in 2015, U.S. banks were required to use a new approach in order to compute their risk weighted assets, which include exchange-traded options and futures. This, and other rulemaking, may lead to further increases in capital requirements for U.S. bank holding companies, and bank subsidiaries involveddifficulty in the ~~trading~~post-Merger integration process and ~~clearing of derivatives. These increased capital requirements~~ may ~~reduce trading in options and futures due~~not be able to ~~bank-affiliated broker-dealers reducing their own trading, charging their customers more to trade or reducing the number of certain customers.~~

In 2016, the SEC published a proposed plan by self-regulatory organizations ("SROs") responding to a 2012 SEC directive that SROs submit a plan to create, implement and maintain a consolidated audit trail, which would serve as a comprehensive audit trail of orders that will allow regulators to efficiently and accurately track all activity in Regulation NMS securities in the U.S. market. In addition to increased regulatory obligations, implementation of a consolidated audit trail could result in significant additional expenditures, including to implement any new technology to meet any plan's requirements.

Under European Union ("EU") regulations, European banks and other European financial institutions become subject to punitive capital charges if they transact options or futures through a non-qualifying clearinghouse. OCC, our clearinghouse for options and futures, is not currently recognized as a qualified clearinghouse by the EU. The current deadline for the EU to qualify foreign clearinghouses as equivalent is December 15, 2016. If the EU does not recognize OCC as a qualified clearinghouse byadequately replace such date (or by a subsequent date in the event that the current deadline is extended), then European market participants that clear through OCC would become subject to punitive capital charges. As a result, we could experience the loss of a significant number of European market participants and a significant reduction in trading activity on our markets,personnel, which could have a material adverse effect on the combined company’s overall business, results of operations and financial condition.

Our and Bats’ employees may experience uncertainty about their future roles with the combined company until integration strategies for the combined company are announced or executed. These circumstances may adversely affect the combined company’s ability to retain key personnel. The combined company also must continue to motivate employees and maintain their focus on the strategies and goals of the combined company. Doing so may be difficult due to the uncertainty and challenges associated with post-Merger integration. If the combined company is unable to retain executives and other key employees, the roles and responsibilities of such executive officers and employees will need to be filled either by existing or new officers and employees, which may require the combined company to devote time and resources to identifying, hiring and integrating replacements for the departed executives and employees that could otherwise be used to integrate our ~~business.~~and Bats’ businesses or otherwise pursue business opportunities. There can be no assurance that the combined company will be able to retain and motivate its employees in the same manner as weand Bats have historically done.

The combined company may need to hire additional personnel in order to assist with the transition of our businesses to the Bats information technology platform. It may be difficult for the combined company to retain and recruit qualified employees in sufficient numbers, and if the combined company is unable to satisfy its needs for qualified and capable employees, its business and operating results could be adversely affected.

There is substantial competition for qualified and capable personnel in the technology space, which may make it difficult for the combined company to retain and recruit qualified employees in sufficient numbers. Increased difficulty in retaining or recruiting sufficient and qualified personnel by the combined company may lead to increased employment compensation costs, which could adversely affect the combined company’s results of operations. In addition, the increased number of employees may impose a significant administrative burden on the combined company. If the combined company is unable to retain and recruit highly qualified employees by offering competitive compensation, stable work environment and leadership opportunities now and in the future, the combined company’s business and operating results could be negatively impacted.

Bats generates a significant percentage of its total revenues from, and is provided with significant liquidity in its markets and other services by, entities who are affiliates of its significant stockholders, and there is no assurance that such entities will continue to generate such revenue or provide such liquidity and other services after the completion of the Merger.

~~It is also possible~~Bats earns a significant percentage of its revenue from customers who are affiliates of its significant stockholders. In addition, Bats relies on certain entities who are affiliates of significant Bats stockholders to route orders that ~~there~~are not routed directly by Bats and to clear certain trades routed to other markets. The significant stockholders of Bats may not receive shares of our common stock in the Merger, or even if they do, their proportionate stake in the combined company will be ~~additional legislative and regulatory changes~~significantly less than their stake in Bats prior to the Merger, so there may be less incentive for the affiliates of Bats’ significant stockholders to maintain their current business relationships with the combined company following the Merger at current levels or ~~efforts in~~at all. If the ~~environment in which we operate our businesses, although we cannot predict~~affiliates of Bats’ significant stockholders do not remain customers following the ~~nature of these potential changes~~Merger at current levels or ~~their impact on our business~~ at ~~this time. Actions on~~all or if any of the ~~specific regulatory issues currently under review in~~affiliates of Bats’ significant stockholders do not continue to route and clear trades as they did prior to the ~~U.S.~~Merger, the combined company may experience decreased revenues and other proposals could have a material impact on our business. For a discussion of the regulatory environment in which we operate and proposed regulatory changes, see "Business—Regulatory Environment and Compliance" in Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2015.

In addition, Congress, the SEC, foreign regulators and other regulatory authorities could impose legislative or regulatory changes that could adversely impact the ability of our market participants to use our markets. Any such changes could result in the loss of a significant number of market participants or a reduction in trading activity on our markets, either ofbusiness interruptions, which could have a material adverse effect on the business, results of operations and financial condition of the combined company.

The combined company will record goodwill and intangible assets that could become impaired and adversely affect its results of operations and financial condition.

Accounting standards in the United States require that one party to the Merger be identified as the acquirer. In accordance with these standards, the Merger will be accounted for as an acquisition of Bats by usand will follow the acquisition method of accounting for business combinations. The assets and liabilities of Bats will be consolidated with our ~~business. Changes~~assets and liabilities. The excess of the purchase price over the fair values of Bats’ assets and liabilities, if any, will be recorded as goodwill.

We will be required to assess goodwill and intangible assets for impairment at least annually. In the future we may take charges against earnings resulting from impairment. Any determination requiring the write off of a significant portion of our goodwill or ~~proposed changes~~other intangible assets could adversely affect our results of operations and financial condition.

The Merger may not be accretive and may cause dilution to our earnings per share, which may negatively affect the market price of our common stock.

We currently anticipate that the Merger will be accretive to adjusted earnings per share in ~~regulation~~the first year following the completion of the Merger. This expectation is based on preliminary estimates, which may materially change. We could also encounter additional transaction and integration‑related costs or other factors such as the failure to realize all of the benefits anticipated in the Merger. All of these factors could cause dilution to our earnings per share or decrease or delay the expected accretive effect of the Merger and cause a decrease in the price of our common stock.

The combined company will indirectly hold 100% of the issued share capital and voting rights in Bats Trading Limited (“BTL”) and its wholly owned subsidiary, Chi-X Europe Limited (“Chi-X Europe”). As a result, any person who holds, or has voting power with respect to, 10% or more of the outstanding shares of our common stock following the effective time of the Merger, will be subject to certain regulatory requirements under United Kingdom law.

A person that indirectly acquires control in ~~additional costs~~a Financial Conduct Authority (“FCA”) entity is required to file a change in control notice with the FCA. Though both are FCA regulated entities, the statutorily prescribed change in control notification threshold for BTL is acquisition of ~~compliance~~voting power with respect to 20% or more of the issued share capital thereof. The change in control notification threshold for Chi-X Europe is acquisition of voting power with respect to 10% or more of the issued share capital thereof. Therefore, any person who holds, or has voting power with respect to, 10% or more of the outstanding shares of our common stock will be required to file a change in control notice in respect of Chi-X Europe and, ~~modification~~if this holding is in excess of ~~market participants' trading activity on~~20%, also for BTL. This obligation may discourage, delay or prevent accumulations of 10% or more of our ~~exchanges.~~
