Organization and Nature of Operations

Organization and Nature of Operations

1. Organization and Nature of Operations

We are a leading global exchange group that delivers trading, clearing, exchange technology, securities listing, and public company services across six continents. Our global offerings are diverse and include trading and clearing across multiple asset classes, market data products, financial indexes, capital formation solutions, financial services and market technology products and services. Our technology powers markets across the globe, supporting cash equity trading, derivatives trading, clearing and settlement and many other functions.

In the U.S., we operate The NASDAQ Stock Market, a registered national securities exchange. The NASDAQ Stock Market is the largest single cash equities securities market in the U.S. in terms of listed companies and in the world in terms of share value traded. As of March 31, 2011, The NASDAQ Stock Market was home to 2,760 listed companies with a combined market capitalization of approximately $4.8 trillion. In addition, in the U.S. we operate two additional cash equities trading markets, two options markets, a futures market and a derivatives clearinghouse. We also engage in riskless principal trading of over-the-counter, or OTC, power and gas contracts.

In Europe, we operate exchanges in Stockholm (Sweden), Copenhagen (Denmark), Helsinki (Finland), and Iceland as NASDAQ OMX Nordic, and exchanges in Tallinn (Estonia), Riga (Latvia) and Vilnius (Lithuania) as NASDAQ OMX Baltic. Collectively, the exchanges that comprise NASDAQ OMX Nordic and NASDAQ OMX Baltic offer trading in cash equities, bonds, structured products and ETFs, as well as trading and clearing of derivatives and clearing of resale and repurchase agreements. Our Nordic and Baltic operations also offer alternative marketplaces for smaller companies called NASDAQ OMX First North. As of March 31, 2011, the exchanges that comprise NASDAQ OMX Nordic and NASDAQ OMX Baltic, together with NASDAQ OMX First North, were home to 773 listed companies with a combined market capitalization of approximately $1.2 trillion.

We also operate NASDAQ OMX Armenia. In addition, NASDAQ OMX Commodities operates the world's largest power derivatives exchange, one of Europe's largest carbon exchanges and N2EX, a marketplace for physical U.K. power contracts.

In some of the countries where we operate exchanges, we also provide clearing, settlement and depository services.

We manage, operate and provide our products and services in three business segments: Market Services, Issuer Services and Market Technology.

Market Services

Our Market Services segment includes our U.S. and European Transaction Services businesses, as well as our Market Data and Broker Services businesses. We offer trading on multiple exchanges and facilities across several asset classes, including cash equities, derivatives, debt, commodities, structured products and ETFs. In addition, in some of the countries where we operate exchanges, we also provide clearing, settlement and depository services.

U.S. Transaction Services

In the U.S., we offer trading in cash equity securities, derivatives and ETFs on The NASDAQ Stock Market, The NASDAQ Options Market, NASDAQ OMX PHLX, NASDAQ OMX BX, NASDAQ OMX PSX and NASDAQ OMX Futures Exchange, or NFX, and engage in riskless principal trading of OTC power and gas contracts through NASDAQ OMX Commodities Clearing Company, or NOCC. Our transaction-based platforms in the U.S. provide market participants with the ability to access, process, display and integrate orders and quotes for cash equity securities, derivatives and ETFs. The platforms allow the routing and execution of buy and sell orders, as well as the reporting of transactions for cash equity securities, derivatives and ETFs, providing fee-based revenues.

Cash Equities Trading

The NASDAQ Stock Market is the largest single pool of liquidity for trading U.S.-listed cash equities, matching an average of approximately 16.5% of all U.S. cash equities volume for the three months ended March 31, 2011. With NASDAQ OMX BX and NASDAQ OMX PSX, we offer a second and third quote within the U.S. cash equities marketplace providing our customers enhanced trading choices and pricing flexibility within the U.S. cash equities marketplace. During the three months ended March 31, 2011, NASDAQ OMX BX matched an average of approximately 1.8% of all U.S. cash equities volume and NASDAQ OMX PSX matched an average of approximately 0.9% of all U.S. cash equities volume.

U.S. Derivative Trading and Clearing

In the U.S., we operate The NASDAQ Options Market and NASDAQ OMX PHLX for the trading of equity options, ETF options, index options and currency options. As of March 31, 2011, NASDAQ OMX PHLX was the largest options market in the U.S. NASDAQ OMX PHLX operates a hybrid electronic and floor-based market as a distinct market alongside The NASDAQ Options Market. During the three months ended March 31, 2011, NASDAQ OMX PHLX and The NASDAQ Options Market had an average combined market share of approximately 28.7% in the U.S. equity options market, consisting of approximately 23.5% at NASDAQ OMX PHLX and approximately 5.2% at The NASDAQ Options Market. Together, the combined market share of 28.7% represented the largest share of the U.S. equity and ETF options market. Our options trading platforms provide trading opportunities to both retail investors and high frequency trading firms, who tend to prefer electronic trading, and institutional investors, who typically pursue more complex trading strategies and often prefer to trade on the floor.

In the U.S., we also operate NFX which offers trading for currency futures and other financial futures. Most futures traded on NFX clear at The Options Clearing Corporation, or OCC. In addition, NFX serves as the designated contract market for interest rate swap futures that are cleared through International Derivatives Clearinghouse, LLC, or IDCH.

Through IDCH, our majority-owned subsidiary International Derivatives Clearing Group, or IDCG, brings a centrally-cleared solution to the largest segment of the OTC derivatives marketplace, specifically interest rate derivative products. IDCH acts as the central counterparty, or CCP, for clearing interest rate swap futures contracts. IDCH utilizes NASDAQ OMX matching and clearing technology to clear and settle these interest rate derivative products.

With the purchase of the assets of North American Energy Credit and Clearing Corp. in March 2010 by our subsidiary NOCC, NASDAQ OMX expanded its presence in the OTC energy commodity markets.

European Transaction Services

Nordic Transaction Services

The exchanges that comprise NASDAQ OMX Nordic offer trading for cash equities and bonds, trading and clearing services for derivatives, and beginning September 2010, clearing services for resale and repurchase agreements. Our platform allows the exchanges to share the same trading system which enables efficient cross-border trading and settlement, cross membership and a single source for Nordic market data.

Trading is offered in Nordic securities such as cash equities and depository receipts, warrants, convertibles, rights, fund units, ETFs, bonds and other interest-related products. NASDAQ OMX Stockholm and NASDAQ OMX Copenhagen also offer trading in derivatives, such as stock options and futures, index options and futures, fixed-income options and futures and stock loans. Settlement and registration of cash trading takes place in Sweden, Finland, Denmark and Iceland via the local central securities depositories.

On NASDAQ OMX Stockholm, we offer clearing services for fixed-income options and futures, stock options and futures and index options and futures by serving as the CCP. In doing so, we guarantee the completion of the transaction and market participants can thereby limit their counterparty risk. We also act as the counterparty for certain OTC contracts. Most of our cash equity trades on the exchanges that comprise NASDAQ OMX Nordic are centrally cleared by European Multilateral Clearing Facility N.V., or EMCF, a leading European clearinghouse in which we own a 22% equity stake.

For further discussion of our Nordic clearing operations, see "Open Clearing Contracts at NASDAQ OMX Commodities and NASDAQ OMX Stockholm," of Note 13, "Fair Value of Financial Instruments."

Baltic Transaction Services

NASDAQ OMX Baltic operations comprise the exchanges in Tallinn (Estonia), Riga (Latvia) and Vilnius (Lithuania). As of March 31, 2011, NASDAQ OMX owns NASDAQ OMX Tallinn and has majority ownerships in NASDAQ OMX Vilnius and NASDAQ OMX Riga. In addition, NASDAQ OMX Tallinn owns the central securities depository in Estonia, NASDAQ OMX Riga owns the central securities depository in Latvia, and NASDAQ OMX Helsinki and NASDAQ OMX Vilnius have an equity interest in the central securities depository in Lithuania.

The exchanges that comprise NASDAQ OMX Baltic offer their members trading, clearing, payment and custody services. Issuers, primarily large local companies, are offered listing and a distribution network for their securities. The securities traded are mainly cash equities, bonds and treasury bills. Clearing, payment and custody services are offered through the central securities depositories in Estonia, Latvia and Lithuania. In addition, in Estonia and Latvia, NASDAQ OMX offers registry maintenance of fund units included in obligatory pension funds, and in Estonia, NASDAQ OMX offers the maintenance of shareholder registers for listed companies. The Baltic central securities depositories offer a complete range of cross-border settlement services.

Pan-European Transaction Services

In the second quarter of 2010, we made a strategic decision to close the business of NASDAQ OMX Europe, or NEURO. We retained our London office and data hub, where we support trading and market data clients, run the U.K. power exchange N2EX and manage our overseas listings operation. As a result of this decision, we recorded a loss of $6 million in the second quarter of 2010. Our decision to close the business of NEURO will not have a significant impact on our future results of operations.

Commodities Trading and Clearing

NASDAQ OMX Commodities offers derivatives and carbon products, operates a clearing business and offers consulting services to commodities markets globally. With our acquisition of Nord Pool in May 2010, NASDAQ OMX Commodities' offering now includes the world's largest power derivatives exchange and one of Europe's largest carbon exchanges.

NASDAQ OMX Commodities has 356 members across a wide range of energy producers and consumers, as well as financial institutions. NASDAQ OMX Commodities' offering is designed for banks, brokers, hedge funds and other financial institutions, as well as power utilities, industrial, manufacturing and oil companies. NASDAQ OMX Commodities offers clearing services for energy derivative and carbon product contracts by serving as the CCP. In doing so, we guarantee the completion of the transaction and market participants can thereby limit their counterparty risk. We also act as the counterparty for certain trades on OTC derivative contracts. In January 2011, NASDAQ OMX Commodities launched trading and clearing of futures based on the N2EX spot market.

For further discussion of our NASDAQ OMX Commodities clearing operations, see "Derivative Positions, at Fair Value," of Note 13, "Fair Value of Financial Instruments."

Access Services

We provide market participants with several alternatives for accessing our markets for a fee. We provide co-location services to market participants whereby firms may lease space for equipment within our data center. These participants are charged monthly fees for cabinet space, connectivity and support. In addition, we earn revenues from annual and monthly exchange membership and registration fees. Access Services revenues also include revenues from FTEN, Inc., or FTEN, which we acquired in December 2010. For further discussion of our acquisition of FTEN, see Note 4, "Acquisitions."

Market Data

We earn Market Data revenues from U.S. tape plans and U.S. and European proprietary market data products.

Net U.S. Tape Plans

The NASDAQ Stock Market operates as the exclusive Securities Information Processor of the Unlisted Trading Privileges Plan, or the UTP Plan, for the collection and dissemination of best bid and offer information and last transaction information from markets that quote and trade in NASDAQ-listed securities. The NASDAQ Stock Market, NASDAQ OMX BX and NASDAQ OMX PSX are participants in the UTP Plan and share in the net distribution of revenue according to the plan on the same terms as the other plan participants. In the role as the Securities Information Processor, The NASDAQ Stock Market collects and disseminates quotation and last sale information for all transactions in NASDAQ-listed securities whether traded on The NASDAQ Stock Market or other exchanges. We sell this information to market participants and to data distributors, who then provide the information to subscribers. After deducting costs associated with our role as an exclusive Securities Information Processor, as permitted under the revenue sharing provision of the UTP Plan, we distribute the tape revenues to the respective UTP Plan participants, including The NASDAQ Stock Market, NASDAQ OMX BX and NASDAQ OMX PSX, based on a formula required by Regulation NMS that takes into account both trading and quoting activity. In addition, all quotes and trades in New York Stock Exchange, or NYSE,- and NYSE Amex-listed securities are reported and disseminated in real time, and as such, we share in the tape revenues for information on NYSE- and NYSE Amex-listed securities.

U.S. Market Data Products

Our market data products enhance transparency and provide critical information to professional and non-professional investors. We collect, process and create information and earn revenues as a distributor of our own, as well as select third-party content. We provide varying levels of quote and trade information to market participants and to data distributors, who in turn provide subscriptions for this information. Our systems enable distributors to gain direct access to our market depth, index values, mutual fund valuation, order imbalances, market sentiment and other analytical data. We earn revenues primarily based on the number of data subscribers and distributors of our data.

European Market Data Products

The exchanges that comprise NASDAQ OMX Nordic, NASDAQ OMX Baltic and NASDAQ OMX Commodities offer European market data products and services. These data products and services provide critical market transparency to professional and non-professional investors who participate in European marketplaces and, at the same time, give investors greater insight into these markets.

European market data products and services are based on the trading information from the exchanges that comprise NASDAQ OMX Nordic, NASDAQ OMX Baltic and NASDAQ OMX Commodities for four classes of assets: cash equities, bonds, derivatives and commodities. We provide varying levels of quote and trade information to market participants and to data distributors, who in turn provide subscriptions for this information. Revenues from European market data are subscription-based and are generated primarily based on the number of data subscribers and distributors of our data.

Broker Services

Our Broker Services operations offer technology and customized securities administration solutions to financial participants in the Nordic market. Broker Services provide services through a registered securities company which is regulated by the Swedish Financial Supervisory Authority. The primary services consist of flexible back-office systems, which allow customers to entirely or partly outsource their company's back-office functions.

We offer customer and account registration, business registration, clearing and settlement, corporate action handling for reconciliations and reporting to authorities. Available services also include direct settlement with the Nordic central securities depositories, real-time updating and communication via the Society for Worldwide Interbank Financial Telecommunication to deposit banks. Revenues are based on a fixed basic fee for back-office brokerage services, such as administration or licensing, maintenance and operations, and a variable portion that depends on the number of transactions completed.

Issuer Services

Our Issuer Services segment includes our Global Listing Services and Global Index Group businesses.

We operate a variety of listing platforms around the world to provide multiple global capital raising solutions for private and public companies. Our main listing markets are The NASDAQ Stock Market and the exchanges that comprise NASDAQ OMX Nordic and NASDAQ OMX Baltic. We offer a consolidated global listing application to companies to enable them to apply for listing on The NASDAQ Stock Market and the exchanges that comprise NASDAQ OMX Nordic and NASDAQ OMX Baltic, as well as NASDAQ Dubai Limited, or NASDAQ Dubai.

Global Listing Services

Our Global Listing Services business includes our U.S. Listings, European Listings and Corporate Solutions businesses.

U.S. Listings

Companies listed on The NASDAQ Stock Market represent a diverse array of industries including health care, consumer products, telecommunication services, information technology, financial services, industrials and energy. There are three types of fees applicable to companies that list on The NASDAQ Stock Market: an annual renewal fee, a listing of additional shares fees and an initial listing fee. Annual renewal fees for securities listed on The NASDAQ Stock Market are based on total shares outstanding. The fee for listing of additional shares is also based on the total shares outstanding, which we review quarterly, and the initial listing fee for securities listed on The NASDAQ Stock Market includes a listing application fee and a total shares outstanding fee.

European Listings

We also offer listings on our Nordic and Baltic exchanges and NASDAQ OMX First North. Revenues are generated through annual fees paid by companies listed on these exchanges, which are measured in terms of the listed company's market capitalization on a trailing 12-month basis. Our European listing customers are organizations such as companies, funds or governments that issue and list securities on the exchanges of NASDAQ OMX Nordic and NASDAQ OMX Baltic. Customers issue securities in the forms of cash equities, depository receipts, warrants, ETFs, convertibles, rights, options, bonds and fixed-income related products.

For smaller companies and growth companies, we offer access to the financial markets through the NASDAQ OMX First North alternative marketplaces.

Corporate Solutions

Our Corporate Solutions business provides customer support services, products and programs to companies, including companies listed on our exchanges. Through our Corporate Solutions offerings, companies gain access to innovative products and services that ease transparency, maximize board efficiency and facilitate better corporate governance.

Global Index Group

We develop and license NASDAQ OMX branded indexes, associated derivatives and financial products as part of our Global Index Group. We believe that these indexes and products leverage, extend and enhance the NASDAQ OMX brand. License fees for our trademark licenses vary by product based on a percentage of underlying assets, dollar value of a product issuance, number of products or number of contracts traded. In addition to generating licensing revenues, these products, particularly mutual funds and ETFs, lead to increased investments in companies listed on our global exchanges, which enhances our ability to attract new listings. We also license cash-settled options, futures and options on futures on our indexes.

Market Technology

The Market Technology segment delivers technology and services to marketplaces, brokers and regulators throughout the world. Market Technology provides technology solutions for trading, clearing, settlement and information dissemination, and also offers facility management integration, surveillance solutions and advisory services to over 70 exchanges, clearing organizations and central securities depositories in more than 50 countries. We serve as a technology partner to some of the world's most prominent exchanges, and we also provide critical technical support to start-ups and new entrants in the exchange space. Revenues are derived from the following primary sources:

•

license, support and facility management revenues;

•

delivery project revenues; and

•

change request, advisory and broker surveillance revenues.

License and support revenues are derived from the system solutions developed and sold by NASDAQ OMX. After we have developed and sold a system solution, the customer licenses the right to use the software and may require post contract support and other services. Facility management revenues are derived when NASDAQ OMX assumes responsibility for the continuous operation of a system platform for a customer.

Delivery project revenues are derived from the installation phase of the system solutions developed and sold by NASDAQ OMX. The majority of our delivery projects involve individual adaptations to the specific requirements of the customer, such as those relating to functionality and capacity.

Change request revenues include customer specific adaptations and modifications of the system solution sold by NASDAQ OMX after delivery has occurred. Advisory services are designed to support our customers' strategies and help them with critical decisions in a highly demanding business environment. Broker surveillance revenues are derived from surveillance solutions targeting brokers and regulators throughout the world.

For further discussion of our segments, see Note 16, "Segments."

Basis of Presentation and Principles of Consolidation	3 Months Ended
Basis of Presentation and Principles of Consolidation	Mar. 31, 2011
Basis of Presentation and Principles of Consolidation
Basis of Presentation and Principles of Consolidation	2. Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The accompanying unaudited condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal recurring nature. The financial statements include the accounts of NASDAQ OMX, its wholly-owned subsidiaries and other entities in which NASDAQ OMX has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. We consolidate those entities in which we are the primary beneficiary of a variable-interest entity, or VIE, and entities where we have a controlling financial interest. We were not the primary beneficiary of any VIE during the three months ended March 31, 2011 and 2010. When NASDAQ OMX is not the primary beneficiary of a VIE or does not have a controlling interest in an entity but exercises significant influence over the entity's operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See "Equity Method Investments" of Note 6, "Investments," for further discussion of our equity method investments. As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in NASDAQ OMX's Annual Report on Form 10-K for the fiscal year ended December 31, 2010. Certain prior year amounts have been reclassified to conform to the current year presentation. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. We have evaluated our subsequent events through the issuance date of this Quarterly Report on Form 10-Q. See Note 17, "Subsequent Events," for further discussion. Income Taxes We use the asset and liability method to provide income taxes on all transactions recorded in the condensed consolidated financial statements. Deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities (i.e., temporary differences) and are measured at the enacted rates that will be in effect when these differences are realized. If necessary, a valuation allowance is established to reduce deferred tax assets to the amount that is more likely than not to be realized. In order to recognize and measure our unrecognized tax benefits, management determines whether a tax position is more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Once it is determined that a position meets the recognition thresholds, the position is measured to determine the amount of benefit to be recognized in the condensed consolidated financial statements. Interest and/or penalties related to income tax matters are recognized in income tax expense. In the fourth quarter of 2010, we received an appeal from the Finnish Tax Authority in which such authority challenges certain interest expense deductions claimed by NASDAQ OMX in Finland for the years 2009 and 2008. NASDAQ OMX's tax return position with respect to this deduction was previously reviewed and approved by the Finnish Tax Authority. The appeal also demands certain penalties be paid with regards to such tax return filing position. If the Finnish Tax Authority prevails in their challenge, additional tax and penalties for such years would total approximately $10 million. We expect the Finnish Tax Authority to agree with our position once its review is completed and, as such, believe it is unlikely NASDAQ OMX will be assessed any additional tax and penalties. Through March 31, 2011, we have recorded the tax benefits associated with such filing position. In June 2009, NASDAQ OMX filed an application for an advance tax ruling with the Swedish Tax Council for Advance Tax Rulings. The application was filed to confirm whether certain interest expense is deductible for Swedish tax purposes under legislation that became effective on January 1, 2009. In June 2010, we received a favorable response from the Swedish Tax Council for Advance Tax Rulings in which all members of the Council agreed that such interest expense is deductible for Swedish tax purposes. The Swedish Tax Agency has appealed such ruling to the Swedish Supreme Administrative Court. We expect the Swedish Supreme Administrative Court to agree with the ruling from the Swedish Tax Council for Advance Tax Rulings. In the first quarter of 2011, we recorded a tax benefit of $5 million, or $0.03 per diluted share and in the first quarter of 2010, we recorded a tax benefit of $5 million, or $0.02 per diluted share, related to this matter. Since January 1, 2009, we have recorded a tax benefit of $42 million, or $0.20 per diluted share, related to this matter.

3. Recently Adopted Accounting Pronouncements

ASC Topic 820 —In January 2010, the Financial Accounting Standards Board, or FASB, issued amended guidance relating to FASB Accounting Standards Codification, or ASC, Topic 820, "Fair Value Measurements and Disclosures." The amended guidance requires new disclosures as follows:

•

Amounts related to transfers in and out of Levels 1 and 2 shall be disclosed separately and the reasons for the transfers shall be described.

•

In the reconciliation for fair value measurements using significant unobservable inputs (Level 3), a reporting entity should present separately information about purchases, sales, issuances, and settlements on a gross basis.

The guidance also provides amendments that clarify existing disclosures related to the following:

•

Reporting fair value measurement disclosures for each class of assets and liabilities.

•

Providing disclosure surrounding the valuation techniques and inputs used to measure fair value for both Level 2 and Level 3 fair value measurements.

This accounting guidance was effective for us beginning on January 1, 2010, except for the disclosure requirements surrounding the reconciliation of Level 3 fair value measurements, which were effective for us on January 1, 2011. Since this guidance only required additional disclosure, it did not affect our financial position or results of operations.

4. Acquisitions

We completed the following acquisitions in 2010. The results of operations of each transaction are included in our Condensed Consolidated Statements of Income from the dates of each acquisition.


	Purchase Consideration		Total Net (Liabilities) Assets Acquired			Purchased Intangible Assets		Goodwill
	(in millions)
FTEN⁽¹⁾	$	110	$	(1	)	$	46	$	65

Total for 2010	$	204	$	1		$	76	$	127

⁽¹⁾

In December 2010, we acquired FTEN, a leading provider of Real-Time Risk Management solutions for the financial securities market for $110 million. FTEN purchase consideration included $11 million held in escrow to be paid in 2012, in accordance with the purchase agreement. We acquired net assets, at fair value, totaling $3 million and recorded a current deferred tax liability of $2 million and a non-current deferred tax liability of $16 million related to purchased intangible assets, and we also recorded a non-current deferred tax asset of $14 million related to net operating loss carry forwards, resulting in total net liabilities acquired of $1 million. The total deferred tax liabilities of $18 million represent the tax effect of the difference between the estimated assigned fair value of the acquired intangible assets ($46 million) and the tax basis ($0) of such assets. The estimated amount of $18 million is determined by multiplying the difference of $46 million by FTEN's effective tax rate of 39.55%. The purchased intangible assets of $46 million consisted of $23 million in customer relationships, $12 million in technology, $9 million for the FTEN trade name and $2 million related to non-compete agreements.

⁽²⁾

In August 2010, we acquired SMARTS Group Holdings Pty Ltd, or SMARTS, a leading technology provider of surveillance solutions to exchanges, regulators and brokers to diversify our Market Technology business and enter the broker surveillance and compliance market. We completed our acquisition of SMARTS for $77 million, which included a $75 million initial purchase price, as well as a $2 million working capital adjustment. SMARTS purchase consideration also included $2 million held in escrow that was paid in the first quarter of 2011 and $12 million held in escrow to be paid in 2012, in accordance with the purchase agreement. We acquired net assets, at fair value, totaling $3 million and recorded a current deferred tax liability of $1 million and a non-current deferred tax liability of $7 million related to purchased intangible assets, resulting in total net liabilities acquired of $5 million. The total deferred tax liabilities of $8 million represent the tax effect of the difference between the estimated assigned fair value of the acquired intangible assets ($28 million) and the tax basis ($0) of such assets. The estimated amount of $8 million is determined by multiplying the difference of $28 million by SMARTS' effective tax rate of 30%. The purchased intangible assets of $28 million consisted of $11 million in technology and $17 million in customer relationships.

⁽³⁾

In May 2010, we acquired Nord Pool, a derivatives trading market, for $17 million (101 million NOK). We acquired net assets, at fair value, totaling $8 million and recorded deferred tax liabilities of $1 million related to purchased intangible assets, resulting in total net assets acquired of $7 million. Through this acquisition, we now hold a Norwegian exchange license and operate the Nordic power market and the European carbon market on one trading platform.

The above amounts represent the preliminary allocation of the purchase price and are subject to revision during the remainder of the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments to the provisional values during the measurement period will be pushed back to the date of acquisition. Comparative information for periods after acquisition but before the period in which the adjustments are identified will be adjusted to reflect the effects of the adjustments as if they were taken into account as of the acquisition date. Changes to amounts recorded as assets and liabilities may result in a corresponding adjustment to goodwill. There were no adjustments to the provisional values during the three months ended March 31, 2011.

Acquisition of ZVM

In December 2010, we acquired Zoomvision Mamato, or ZVM, a provider of webcasting and investor relation communication services for companies in the Nordic region, for an immaterial amount. ZVM, which is the leading provider of webcasting services in Northern Europe, adds to the growing range of capabilities and services NASDAQ OMX offers public and private companies in the U.S. and Europe.

Acquisition of Assets of North American Energy Credit and Clearing Corp.

In March 2010, we also purchased the assets of North American Energy Credit and Clearing Corp. for an immaterial amount. With this purchase, NASDAQ OMX expanded its presence in the OTC energy commodity markets. As previously discussed, the acquisition of these assets was effected through NOCC. In March 2010, we also provided an additional $25 million in capital to NOCC to improve its liquidity position. As of March 31, 2011 and December 31, 2010, this amount is classified as non-current restricted cash in the Condensed Consolidated Balance Sheets.

Pro Forma Results and Acquisition-related Costs

Pro forma results of operations for the acquisitions completed during 2010 have not been presented since the acquisitions both individually and in the aggregate were not material to our financial results.

For the three months ended March 31, 2011, acquisition-related costs for the 2010 acquisitions described above are included in merger and strategic initiatives expense in the Condensed Consolidated Statements of Income.

The following table presents the changes in goodwill by business segment during the three months ended March 31, 2011:


	Market Services		Issuer Services		Market Technology		Total
	(in millions)
Balance at December 31, 2010	$	4,679	$	292	$	156	$	5,127

Foreign currency translation adjustment		190		14		8		212

Balance at March 31, 2011	$	4,869	$	306	$	164	$	5,339

As of March 31, 2011, the amount of goodwill that is expected to be deductible for tax purposes in future periods is $104 million.

Goodwill represents the excess of the purchase price over the value assigned to the net tangible and identifiable intangible assets of a business acquired. Goodwill is allocated to the reporting units based on the assignment of the fair values of each reporting unit of the acquired company. We are required to test goodwill for impairment at the reporting unit level annually, or in interim periods if certain events occur indicating that the carrying value may be impaired. We test for impairment during the fourth quarter of our fiscal year using October 1^stcarrying values. We considered the need to update our most recent annual goodwill impairment test as of March 31, 2011 and concluded that none of the impairment indicators triggered a revised impairment analysis. As such, we concluded the assumptions used during the annual assessment remained appropriate. There was no impairment of goodwill for the three months ended March 31, 2011 and 2010. Although there is no impairment as of March 31, 2011, events such as economic weakness and unexpected significant declines in operating results of reporting units may result in our having to perform a goodwill impairment test for some or all of our reporting units prior to the required annual assessment. These types of events and the resulting analysis could result in goodwill impairment charges in the future.

Purchased Intangible Assets

Investments	6. Investments Trading Securities Trading securities, which are included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, were $254 million as of March 31, 2011 and $220 million as of December 31, 2010. These securities are primarily comprised of Swedish government debt securities, of which $208 million as of March 31, 2011 and $190 million as of December 31, 2010, are restricted assets to meet regulatory capital requirements primarily for NASDAQ OMX Stockholm's clearing operations. Available-for-Sale Investment Security *Investment in DFM* Our available-for-sale investment security, which is included in financial investments, at fair value in the Condensed Consolidated Balance Sheets, represents our 1% investment in Dubai Financial Market PJSC, or DFM. In May 2010, we completed the exchange of our equity interest in NASDAQ Dubai for a 1% investment in DFM. See "Investment in NASDAQ Dubai" below for further discussion. As of March 31, 2011 and December 31, 2010, the cost basis of this security was $36 million. As of March 31, 2011, the fair value was $29 million and as of December 31, 2010 the fair value was $33 million. The gross change of $7 million between the cost basis and fair value is reflected as an unrealized holding loss in accumulated other comprehensive loss in the Condensed Consolidated Balance Sheets, net of taxes. We reviewed the carrying value of this investment security to determine whether an other-than-temporary decline in value exists. We considered factors affecting the investee, factors affecting the industry the investee operates in and general market trends. We also considered the length of time the market value has been below the cost basis and the near-term prospects for recovery of unrealized losses. As of March 31, 2011 and December 31, 2010, we have not recognized an other-than-temporary decline in value on this investment security. Equity Method Investments The equity method of accounting is used when we own less than 50% of the outstanding voting stock, but exercise significant influence over the operating and financial policies of a company. Equity interest in our equity method investments was $29 million as of March 31, 2011 and $27 million as of December 31, 2010, which consisted primarily of our equity interest in EMCF. Equity method investments are included in other assets in the Condensed Consolidated Balance Sheets. Income (loss) recognized from our equity interest in the earnings and losses of these companies was immaterial for both the three months ended March 31, 2011 and 2010. *Investment in NASDAQ Dubai* In May 2010, we participated in the realignment of the ownership structure of NASDAQ Dubai, in which NASDAQ Dubai became a wholly-owned subsidiary of DFM, a publicly traded company controlled by Borse Dubai Limited, a Dubai company, or Borse Dubai. We received a 1% equity interest in DFM in exchange for our equity interest in NASDAQ Dubai. Our existing technology and trademark licensing arrangements with Borse Dubai and NASDAQ Dubai remain unchanged. NASDAQ Dubai and DFM are related parties, as both of them are primarily owned by Borse Dubai, our largest stockholder.

- Definition

This item represents the entire disclosure related to Investments in Certain Debt and Equity Securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt.

Market Technology deferred revenues include revenues from delivered client contracts in the support phase charged during the period. Under contract accounting, where customization and significant modifications to the software are made to meet the needs of our customers, total revenues as well as costs incurred, are deferred until significant modifications are completed and delivered. Once delivered, deferred revenue and the related deferred costs are recognized over the post contract support period. We have included the deferral of costs in other current assets and other assets in the Condensed Consolidated Balance Sheets. The amortization of Market Technology deferred revenue includes revenues earned from client contracts recognized during the period and from the technology licenses contributed to NASDAQ Dubai.

2.50% Convertible Senior Notes

During the first quarter of 2008, in connection with the business combination with OMX AB, we completed the offering of $475 million aggregate principal amount of 2.50% convertible senior notes due 2013. The interest rate on the notes is 2.50% per annum payable semi-annually in arrears on February 15 and August 15 and will mature on August 15, 2013. In 2009, we repurchased $47 million principal amount of the 2.50% convertible senior notes. As a result of the $47 million repurchase, the remaining aggregate principal amount outstanding on these notes as of March 31, 2011 and December 31, 2010 was $428 million.

The notes are convertible in certain circumstances specified in the indenture for the notes. Upon conversion, holders will receive, at the election of NASDAQ OMX, cash, common stock or a combination of cash and common stock. It is our current intent and policy to settle the principal amount of the notes in cash. The conversion rate will initially be 18.1386 shares of common stock per $1,000 principal amount of notes, which is equivalent to a conversion price of approximately $55.13 per share of common stock. At March 31, 2011 and December 31, 2010, the 2.50% convertible senior notes are convertible into 7,757,283 shares of our common stock, subject to adjustment upon the occurrence of specified events. Subject to certain exceptions, if we undergo a "fundamental change" as described in the indenture, holders may require us to purchase their notes at a price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest.

Since the settlement structure of our 2.50% convertible senior notes permits settlement in cash upon conversion, we are required to separately account for the liability and equity components of the convertible debt in a manner that reflects our nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This entails bifurcation of a component of the debt, classification of that component in equity and then accretion of the resulting discount on the debt being reflected in the income statement as part of interest expense.

The changes in the liability and equity components of our 2.50% convertible senior notes during the three months ended March 31, 2011 are as follows:


	Liability Component							Equity Component
	(in millions)							(in millions)
	Principal Balance		Unamortized Debt Discount			Net Carrying Amount		Gross Equity Component		Deferred Taxes		Net Equity Component
December 31, 2010	$	428	$	40		$	388	$	80	$	32	$	48
Accretion of debt discount		—		(4	)		4		—		—		—

March 31, 2011	$	428	$	36		$	392	$	80	$	32	$	48

The unamortized debt discount on the convertible debt was $36 million as of March 31, 2011 and $40 million as of December 31, 2010 and is included in debt obligations in the Condensed Consolidated Balance Sheets. This amount will be accreted as part of interest expense through the maturity date of the convertible debt of August 15, 2013. The effective annual interest rate on the 2.50% convertible senior notes was 6.53% for the three months ended March 31, 2011 and 2010, which includes the accretion of the debt discount in addition to the annual contractual interest rate of 2.50%.

As of March 31, 2011 and December 31, 2010, the equity component of the convertible debt included in additional paid-in capital in the Condensed Consolidated Balance Sheets was $48 million. This amount is calculated as follows: $80 million of excess principal of the convertible debt over the carrying amount less $32 million of deferred taxes. The deferred tax liability is determined by multiplying the $80 million of excess principal of the convertible debt over the carrying amount by the U.S. marginal tax rate of 39.55%.

Interest expense recognized on our 2.50% convertible senior notes in the Condensed Consolidated Statements of Income for the three months ended March 31, 2011 and 2010 is as follows:


	Three Months Ended March 31,
	2011		2010

Accretion of debt discount	$	4	$	4
Contractual interest		2		2

Total interest expense recognized on our 2.50% convertible senior notes	$	6	$	6

Debt Issuance Costs

In 2008, in conjunction with the issuance of the 2.50% convertible senior notes, we incurred debt issuance costs of $10 million. These costs, which are capitalized and included in other assets in the Condensed Consolidated Balance Sheets, are being amortized over the life of the debt obligation. Amortization expense, which is recorded as additional interest expense for these costs, was immaterial for both the three months ended March 31, 2011 and 2010.

Senior Unsecured Notes and Credit Facility

In January 2010, NASDAQ OMX issued $1 billion of senior unsecured notes, or the Notes, and entered into a $950 million senior unsecured three-year credit facility. The credit facility provides for an unfunded $250 million revolving credit commitment (including a swingline facility and letter of credit facility), a $350 million funded Tranche A term loan, or the Term Loan A, and a $350 million funded Tranche X term loan, or the Term Loan X and, together with Term Loan A, the Term Loans. NASDAQ OMX applied the net proceeds from the Notes, the $700 million funded Term Loans and cash on hand to repay all amounts outstanding under our senior secured credit facilities in place as of December 31, 2009 and related fees. As a result, NASDAQ OMX terminated the associated credit agreement.

The Notes

The Notes were issued at a discount in two separate series consisting of $400 million aggregate principal amount of 4.00% senior notes due 2015, or the 2015 Notes, and $600 million aggregate principal amount of 5.55% senior notes due 2020, or the 2020 Notes. As a result of the discount, the proceeds received from the issuance were less than the aggregate principal amounts. As of March 31, 2011 and December 31, 2010, the balance of $398 million for the 2015 Notes and the balance of $598 million for the 2020 Notes, reflects the aggregate principal amounts, less the unamortized debt discount. The unamortized debt discount will be accreted through interest expense over the life of the Notes.

The 2015 Notes pay interest semiannually at a rate of 4.00% per annum until January 15, 2015, and the 2020 Notes pay interest semiannually at a rate of 5.55% per annum until January 15, 2020. The Notes are general unsecured obligations of ours and rank equally with all of our existing and future unsubordinated obligations. The Notes are not guaranteed by any of our subsidiaries. The Notes were issued under an indenture that, among other things, limits our ability to consolidate, merge or sell all or substantially all of our assets, create liens, and enter into sale and leaseback transactions.

Credit Facility

The credit facility provides for an unfunded $250 million revolving credit commitment (including a swingline facility and letter of credit facility), a $350 million funded Term Loan A and a $350 million funded Term Loan X. The loans under the credit facility have a variable interest rate based on either the London Interbank Offered Rate, or LIBOR, or the Federal Funds Rate, plus an applicable margin that varies with NASDAQ OMX's debt rating.

Under our credit facility, we are required to pay quarterly principal payments of $35 million on our Term Loans. We made required payments of $35 million in the first quarter of 2011.

The credit facility contains financial and operating covenants. Financial covenants include an interest expense coverage ratio and a maximum leverage ratio. Operating covenants include limitations on NASDAQ OMX's ability to incur additional indebtedness, grant liens on assets, enter into affiliate transactions and pay dividends.

The credit facility also contains customary affirmative covenants, including access to financial statements, notice of defaults and certain other material events, maintenance of business and insurance, and events of default, including cross-defaults to our material indebtedness.

NASDAQ OMX is permitted to repay borrowings under the credit facility at any time in whole or in part, without penalty. We also are required to repay loans outstanding under the credit facility with net cash proceeds from sales of property and assets of NASDAQ OMX and its subsidiaries (excluding inventory sales and other sales in the ordinary course of business) and casualty and condemnation proceeds, in each case subject to specified exceptions and thresholds.

Debt Issuance and Other Costs

We incurred debt issuance and other costs of $21 million in connection with the issuance of the Notes and the entry into the new credit facility. These costs, which are capitalized and included in other assets in the Condensed Consolidated Balance Sheets, are being amortized over the life of the debt obligations. Amortization expense, which is recorded as additional interest expense for these costs, was $1 million for both the three months ended March 31, 2011 and March 31, 2010.

In January 2010, as a result of the repayment of our senior secured credit facilities in place as of December 31, 2009, we recorded a pre-tax charge of $40 million, which included the write-off of the remaining unamortized balance of debt issuance costs incurred of $28 million, costs to terminate our float-to-fixed interest rate swaps previously designated as a cash flow hedge of $9 million and other costs of $3 million. These charges are included in general, administrative and other expense in the Condensed Consolidated Statements of Income for the three months ended March 31, 2010.

5.25% Senior Unsecured Notes

In December 2010, NASDAQ OMX issued $370 million of 5.25% senior unsecured notes due 2018, or the 2018 Notes. We applied the net proceeds from the 2018 Notes of $367 million and cash on hand of $3 million to repay all amounts outstanding under our bridge facility, discussed below, as well as related fees.

The 2018 Notes were issued at a discount. As a result of the discount, the proceeds received from the issuance were less than the aggregate principal amount. As of March 31, 2011 and December 31, 2010, the balance of $367 million reflects the aggregate principal amount, less the unamortized debt discount. The unamortized debt discount will be accreted through interest expense over the life of the 2018 Notes.

The 2018 Notes pay interest semiannually at a rate of 5.25% per annum until January 16, 2018 and may vary with NASDAQ OMX's debt rating up to a rate not to exceed 7.25%. The 2018 Notes are general unsecured obligations of ours and rank equally with all of our existing and future unsubordinated obligations. They are not guaranteed by any of our subsidiaries. The 2018 Notes were issued under indentures that among other things, limit our ability to consolidate, merge or sell all or substantially all of our assets, create liens, and enter into sale and leaseback transactions. In addition, upon a change of control triggering event (as defined in the indenture), the terms require us to repurchase all or part of each holder's notes for cash equal to 101% of the aggregate principal amount purchased plus accrued and unpaid interest, if any.

Debt Issuance Costs

We incurred debt issuance costs of $3 million in connection with the issuance of the 2018 Notes. These costs, which are capitalized and included in other assets in the Condensed Consolidated Balance Sheets, are being amortized over the life of the debt obligation. Amortization expense, which is recorded as additional interest expense for these costs, was immaterial for the three months ended March 31, 2011.

Bridge Facility

In December 2010, NASDAQ OMX entered into a $400 million senior unsecured bridge facility, or the bridge facility, and borrowed $370 million to partially finance the purchase of our stock from Borse Dubai. See "Share Repurchase Program and Share Repurchase from Borse Dubai," of Note 12, "NASDAQ OMX Stockholders' Equity," for further discussion of our share repurchase from Borse Dubai. We applied the net proceeds from the issuance of our 2018 Notes, discussed above, and cash on hand to repay all amounts outstanding under the bridge facility and terminated the bridge facility as of December 31, 2010. The effective interest rate on borrowings under the bridge facility was 1.76%.

Other Credit Facilities

In addition to the $250 million revolving credit commitment discussed above, we have credit facilities related to our clearinghouses in order to meet liquidity and regulatory requirements. These credit facilities, which are available in multiple currencies, primarily Swedish Krona and U.S. dollar, totaled $459 million ($208 million in available liquidity and $251 million to satisfy regulatory requirements), none of which was utilized at March 31, 2011. At December 31, 2010, these facilities totaled $440 million ($196 million in available liquidity and $244 million to satisfy regulatory requirements), none of which was utilized.

Debt Covenants

At March 31, 2011, we were in compliance with the covenants of all of our debt obligations.

9. Pension and Other Benefit Programs

U.S. Defined-Benefit Pension and Supplemental Executive Retirement Plans

We maintain non-contributory, defined-benefit pension plans, non-qualified supplemental executive retirement plans, or SERPs, for certain senior executives and post-retirement benefit plans for eligible employees in the U.S., collectively referred to as the NASDAQ OMX Benefit Plans.

Our pension plans and SERPs are frozen. Future service and salary for all participants do not count toward an accrual of benefits under the pension plans and SERPs.

Components of Net Periodic Benefit Cost

The following table sets forth the components of net periodic pension, SERP and post-retirement benefit costs from the NASDAQ OMX Benefit Plans recognized in compensation and benefits expense in the Condensed Consolidated Statements of Income:


	Three Months Ended March 31,
	2011			2010
	(in millions)
Components of net periodic benefit cost
Interest cost	$	2		$	1
Expected return on plan assets		(1	)		(1	)
Recognized net actuarial loss		1			1

Benefit cost	$	2		$	1

Non—U.S. Benefit Plans

Most employees outside the U.S. are covered by local retirement plans or by applicable social laws. Benefits under social laws are generally expensed in the periods in which the costs are incurred. These costs are included in compensation and benefits expense in the Condensed Consolidated Statements of Income and were $4 million for the three months ended March 31, 2011 and $3 million for the three months ended March 31, 2010.

In 2008, as part of the acquisition of Nord Pool's derivatives clearing and consulting subsidiaries, we assumed the obligation for several pension plans providing benefits for their employees. The benefit cost for these plans was immaterial for the three months ended March 31, 2011 and was $1 million for the three months ended March 31, 2010.

Defined Contribution Savings Plan

We sponsor a voluntary defined contribution savings plan, or 401(k) Plan, for U.S. employees. Employees are immediately eligible to make contributions to the plan and are also eligible for an employer contribution match at an amount equal to 100.0% of the first 4.0% of eligible employee contributions. Savings plan expense included in compensation and benefits expense in the Condensed Consolidated Statements of Income was $1 million for both the three months ended March 31, 2011 and 2010.

We have a profit-sharing contribution feature to our 401(k) plan which allows eligible U.S. employees to receive employer retirement contributions, or ERCs, when we meet our annual corporate goals. In addition, we have a supplemental ERC for select highly compensated employees whose ERCs are limited by the annual Internal Revenue Service compensation limit. ERC expense recorded in compensation and benefits expense in the Condensed Consolidated Statements of Income was $1 million for both the three months ended March 31, 2011 and 2010.

Employee Stock Purchase Plan

We have an employee stock purchase plan, or ESPP, under which approximately 3.9 million shares of our common stock have been reserved for future issuance as of March 31, 2011.

Our ESPP allows eligible U.S. and non-U.S. employees to purchase a limited number of shares of our common stock at six-month intervals, called offering periods, at 85.0% of the lower of the fair market value on the first or the last day of each offering period. The 15.0% discount given to our employees is included in compensation and benefits expense in the Condensed Consolidated Statements of Income.

Share-Based Compensation

3 Months Ended

Mar. 31, 2011

Share-Based Compensation

Share-Based Compensation

10. Share-Based Compensation

We have a share-based compensation program that provides our board of directors broad discretion in creating employee equity incentives. Share-based awards, or equity awards, include employee stock options, restricted stock (which includes awards and units) and performance share units, or PSUs. Grants of equity awards are designed to reward employees for their long-term contributions and provide incentives for them to remain with us. For accounting purposes, we consider PSUs to be a form of restricted stock. Restricted stock is generally time-based and vests over two to five-year periods beginning on the date of the grant. Stock options are also generally time-based and expire ten years from the grant date. Stock option awards granted prior to January 1, 2005 generally vested 33% on each annual anniversary of the grant date over three years. Stock option and restricted stock awards granted after January 1, 2005 generally include performance-based accelerated vesting features based on achievement of specific levels of corporate performance. If NASDAQ OMX exceeds the applicable performance parameters, the grants vest on the third anniversary of the grant date, if NASDAQ OMX meets the applicable performance parameters, the grants vest on the fourth anniversary of the grant date, and if NASDAQ OMX does not meet the applicable performance parameters, the grants vest on the fifth anniversary of the grant date.

PSUs are based on performance measures that impact the amount of shares that each recipient will receive upon vesting. PSUs are granted at the fair market value of our stock on the grant date and compensation cost is recognized over the performance period and, in certain cases, an additional vesting period. For each grant of PSUs, an employee may receive from 0% to 150% of the target amount granted, depending on the achievement of performance measures. We report the target number of PSUs granted, unless we have determined that it is more likely than not, based on the actual achievement of performance measures, that an employee will receive a different amount of shares underlying the PSUs, in which case we report the amount of shares the employee is likely to receive.

Summary of 2011 Equity Awards

In March 2011, we granted non-qualified stock options and/or restricted stock to most active employees. Both the stock options and restricted stock granted included a performance-based accelerated vesting feature based on achievement of specific levels of corporate performance, as described above.

In March 2011, certain executive officers received grants of 571,655 PSUs. Of these PSUs granted, 100,000 units are subject to a three year performance period and vest at the end of the period. The remaining 471,655 units are subject to a one year performance period and generally will vest ratably on an annual basis on December 31, 2012 through December 31, 2014.

During 2010, certain grants exceeded the applicable performance parameters for the one year performance PSUs. As a result, an additional 19,142 units were considered granted in February 2011.

See "Summary of Stock Option Activity" and "Summary of Restricted Stock and PSU Activity" below for further discussion.

Common Shares Available Under Our Equity Incentive Plan

As of March 31, 2011, we had approximately 6.1 million shares of common stock authorized for future issuance under our equity incentive plan.

Summary of Share-Based Compensation Expense

The following table shows the total share-based compensation expense resulting from equity awards and the 15.0% discount for the ESPP for the three months ended March 31, 2011 and 2010 in the Condensed Consolidated Statements of Income:


	Three Months Ended March 31,
	2011			2010
	(in millions)
Share-based compensation expense before income taxes	$	7		$	8
Income tax benefit		(3	)		(3	)

Share-based compensation expense after income taxes	$	4		$	5

We estimated the fair value of stock option awards using the Black-Scholes valuation model with the following weighted-average assumptions:


	Three Months Ended March 31,
	2011			2010
Expected life (in years)		5			5
Weighted-average risk free interest rate		2.18	%		2.27	%
Expected volatility		27.0	%		32.0	%
Dividend yield		—			—
Weighted-average fair value at grant date	$	7.06		$	6.36

Our computation of expected life is based on historical exercise patterns. The interest rate for periods within the expected life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. Our computation of expected volatility is based on a market-based implied volatility. Our credit facilities limit our ability to pay dividends. Before our credit facilities were in place, it was not our policy to declare or pay cash dividends on our common stock.

Summary of Stock Option Activity

A summary of stock option activity for the three months ended March 31, 2011 is as follows:


	Stock Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term		Aggregate Intrinsic Value
						(in years)		(in millions)
Outstanding at January 1, 2011		10,112,842		$	16.92		5.7	$	89

Grants ⁽¹⁾		1,234,068			25.28
Exercises		(463,357	)		10.48
Forfeitures or expirations		(183,031	)		23.56

Outstanding at March 31, 2011		10,700,522		$	18.05		6.1	$	99

Exercisable at March 31, 2011		5,642,250		$	13.46		3.7	$	83

⁽¹⁾	Primarily reflects our company wide equity grant issued in March 2011, which includes a performance-based accelerated vesting feature based on achievement of specific levels of corporate performance, as described above.

We received net cash proceeds of $5 million from the exercise of approximately 0.5 million stock options for the three months ended March 31, 2011 and received net cash proceeds of $1 million from the exercise of approximately 0.2 million stock options for the three months ended March 31, 2010. We present excess tax benefits from the exercise of stock options, if any, as financing cash flows.

The aggregate intrinsic value in the above table represents the total pre-tax intrinsic value (i.e., the difference between our closing stock price on March 31, 2011 of $25.84 and the exercise price, times the number of shares) based on stock options with an exercise price less than NASDAQ OMX's closing price of $25.84 as of March 31, 2011, which would have been received by the option holders had the option holders exercised their stock options on that date. This amount changes based on the fair market value of our common stock. The total number of in-the-money stock options exercisable as of March 31, 2011 was 4.5 million.

As of March 31, 2010, 6.6 million outstanding stock options were exercisable and the weighted-average exercise price was $12.57.

Total fair value of stock options vested was immaterial for both the three months ended March 31, 2011 and 2010. The total pre-tax intrinsic value of stock options exercised was $7 million for the three months ended March 31, 2011 and $2 million for the three months ended March 31, 2010.

At March 31, 2011, $18 million of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.9 years.

Summary of Restricted Stock and PSU Activity

The following table summarizes our restricted stock and PSU activity for the three months ended March 31, 2011:


	Restricted Stock			Weighted-Average Grant Date Fair Value		PSUs			Weighted-Average Grant Date Fair Value
Unvested balances at January 1, 2011		2,759,091		$	22.00		1,098,629		$	24.25
Granted⁽ ¹ ⁾		1,029,911			25.47		590,797			25.19
Vested		(20,993	)		28.05		(67,057	)		35.94
Forfeited		(223,822	)		38.82		(123,272	)		28.88

Unvested balances at March 31, 2011		3,544,187		$	23.02		1,499,097		$	23.72

⁽¹⁾	Restricted stock grants in 2011 primarily reflect our company wide grant issued in March 2011, which included a performance- based accelerated vesting feature based on achievement of specific levels of corporate performance, as described above.

At March 31, 2011, $61 million of total unrecognized compensation cost related to restricted stock and PSUs is expected to be recognized over a weighted-average period of 2.0 years.

Basic and diluted earnings per share:
Basic earnings per share	$	0.59	$	0.29

Diluted earnings per share	$	0.57	$	0.28

⁽¹⁾

The decrease in the weighted-average common shares outstanding for basic earnings per share primarily reflects the weighted-average impact of the share repurchase from Borse Dubai and purchases related to our share repurchase program completed in 2010. See "Share Repurchase Program and Share Repurchase from Borse Dubai," of Note 12, "NASDAQ OMX Stockholders' Equity," for further discussion.

Stock options to purchase 10,700,522 shares of common stock, 5,043,284 shares of restricted stock and PSUs, and convertible notes convertible into 34,482 shares of common stock were outstanding at March 31, 2011. For the three months ended March 31, 2011, we included 6,020,652 of the outstanding stock options and 3,434,666 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. The remaining stock options and shares of restricted stock and PSUs are antidilutive, and as such, they were properly excluded.

The 3.75% convertible notes are accounted for under the if-converted method, as we settled the convertible notes in shares of our common stock. For the three months ended March 31, 2011, all of the shares underlying the outstanding 3.75% convertible notes were included in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive.

The 2.50% convertible senior notes are accounted for under the treasury stock method as it is our intent and policy to settle the principal amount of the notes in cash. Based on the settlement structure of the 2.50% convertible senior notes, which permits the principal amount to be settled in cash and the conversion premium to be settled in shares of our common stock or cash, we will reflect the impact of the convertible spread portion of the convertible notes in the diluted calculation using the treasury stock method. For the three months ended March 31, 2011 and 2010, the conversion spread of our 2.50% convertible senior notes was out of the money, and as such, they were properly excluded from the computation of diluted earnings per share.

Stock options to purchase 11,076,397 shares of common stock, 4,282,323 shares of restricted stock and PSUs, and convertible notes convertible into 34,482 shares of common stock were outstanding at March 31, 2010. For the three months ended March 31, 2010, we included 5,400,941 of the outstanding stock options and 1,170,536 shares of restricted stock and PSUs in the computation of diluted earnings per share, on a weighted-average basis, as their inclusion was dilutive. The remaining stock options and shares of restricted stock and PSUs are antidilutive, and as such, they were properly excluded.

NASDAQ OMX Stockholders' Equity	3 Months Ended
NASDAQ OMX Stockholders' Equity	Mar. 31, 2011
NASDAQ OMX Stockholders' Equity
NASDAQ OMX Stockholders' Equity	12. NASDAQ OMX Stockholders' Equity Common Stock At March 31, 2011, 300,000,000 shares of our common stock were authorized, 213,377,707 shares were issued and 176,300,916 shares were outstanding. The holders of common stock are entitled to one vote per share, except that our certificate of incorporation limits the ability of any person to vote in excess of 5.0% of the then-outstanding shares of NASDAQ OMX common stock. This limitation does not apply to persons exempted from this limitation by our board of directors prior to the time such person owns more than 5.0% of the then-outstanding shares of NASDAQ OMX common stock. In 2008, we issued 60,561,515 shares of common stock to Borse Dubai and a trust for Borse Dubai's economic benefit in connection with the OMX AB business combination. In December 2010, we purchased 22,781,000 shares of our common stock from Borse Dubai. See "Share Repurchase Program and Share Repurchase from Borse Dubai" below for further discussion. In addition, Borse Dubai agreed to sell in a private transaction 8,000,000 shares of our stock to Nomura International plc. Nomura International plc agreed, under a forward sale agreement, to sell these 8,000,000 shares to Investor AB. As a result of the settlement of this forward sale agreement, Investor AB's ownership in NASDAQ OMX increased to 17,004,142 shares. As of March 31, 2011, Borse Dubai and a trust for Borse Dubai's economic benefit held 29,780,515 shares of our common stock. In addition, as of December 31, 2010, SLP held 10,539,614 shares of our common stock, and subsequently sold these shares in February 2011. Investor AB purchased 1,000,000 of the shares sold by SLP and owns 18,004,142 shares of our common stock as of March 31, 2011. Common Stock in Treasury, at Cost We account for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to NASDAQ OMX stockholders' equity and included in common stock in treasury, at cost in the Condensed Consolidated Balance Sheets. When treasury shares are reissued, they are recorded at the average cost of the treasury shares acquired. As of March 31, 2011, we held 37,076,791 shares of common stock in treasury and held 37,587,403 shares as of December 31, 2010. *Share Repurchase Program and Share Repurchase from Borse Dubai* During 2010, our board of directors approved a share repurchase program authorizing NASDAQ OMX to repurchase in the aggregate up to $550 million of our outstanding common stock. During 2010, we repurchased 15,050,647 shares of our common stock at an average price of $19.95, with an aggregate purchase price of $300 million. In December 2010, our board of directors also approved the repurchase of 22,781,000 shares of our common stock from Borse Dubai for $21.82 per share for an aggregate purchase price of approximately $497 million. The share repurchase from Borse Dubai expanded, accelerated and completed our share repurchase program. The shares repurchased under the share repurchase program and from Borse Dubai are available for general corporate purposes. *Other Repurchases of Common Stock* For the three months ended March 31, 2011, we repurchased 33,174 shares of our common stock in settlement of employee tax withholding obligations due upon the vesting of restricted stock. Preferred Stock Our certificate of incorporation authorizes the issuance of 30,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. At March 31, 2011 and December 31, 2010, 1,600,000 shares of series A convertible preferred stock were issued and none were outstanding.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

13. Fair Value of Financial Instruments

Fair Value Measurement—Definition and Hierarchy

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability, or the exit price, in an orderly transaction between market participants at the measurement date. Fair value measurement establishes a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect NASDAQ OMX's market assumptions. These two types of inputs create the following fair value hierarchy:

•

Level 1—Quoted prices for identical instruments in active markets.

•

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•

Level 3—Instruments whose significant value drivers are unobservable.

This hierarchy requires the use of observable market data when available.

The following table presents for each of the above hierarchy levels, our financial assets and liabilities that are measured at fair value on a recurring basis at March 31, 2011.

Open Clearing Contracts at NASDAQ OMX Commodities and NASDAQ OMX Stockholm

Derivative Positions, at Fair Value

Through our clearing operations in the derivative markets with NASDAQ OMX Commodities and NASDAQ OMX Stockholm, we are the legal counterparty for each derivative position traded and thereby guarantee the fulfillment of each contract. We also act as the counterparty for certain trades on OTC derivative contracts. The derivatives are not used by NASDAQ OMX Commodities or NASDAQ OMX Stockholm for the purpose of trading on their own behalf. As the legal counterparty of each transaction, NASDAQ OMX Commodities and NASDAQ OMX Stockholm bear the counterparty risk between the purchaser and seller in the contract. The counterparty risks are measured using models that are agreed to with the Financial Supervisory Authority of the applicable country, which requires us to provide minimum guarantees and maintain certain levels of regulatory capital.

The structure and operations of NASDAQ OMX Commodities and NASDAQ OMX Stockholm differ from most other clearinghouses. NASDAQ OMX Commodities and NASDAQ OMX Stockholm are not member-owned organizations, do not maintain a guarantee fund to which members contribute and do not enforce loss sharing assessments amongst members. In addition, unlike most other clearinghouses, they do not record any margin deposits and guarantee funds in the Condensed Consolidated Balance Sheets, as all risks and rewards of collateral ownership, including interest, belongs to the counterparty. Market participants must provide collateral to cover the daily margin call as needed, which is in addition to the initial collateral placed when entering into the transaction. Acceptable collateral is cash and eligible securities in a pledged bank account and/or an on-demand guarantee. All collateral is maintained at a third-party custodian bank for the benefit of the clearing members and is accessible by NASDAQ OMX in the event of default. In addition, market participants must meet certain minimum financial standards to mitigate the risk if they become unable to satisfy their obligations. For NASDAQ Commodities, trading on the contracts can take place up until the delivery period which can occur over a period of several years. For NASDAQ OMX Stockholm, following the completion of a transaction, settlement primarily takes place between parties by net cash settlement or with the exchange of securities and funds. For those transactions where there is an exchange of securities and funds, the transfer of ownership is registered and the securities are stored on the owner's behalf.

The fair value of these derivative contracts with NASDAQ OMX Commodities and NASDAQ OMX Stockholm is reported gross in the Condensed Consolidated Balance Sheets as a receivable pertaining to the purchasing party and a payable pertaining to the selling party. Such receivables and payables attributable to outstanding derivative positions have been netted to the extent that such a legal offset right exists and, at the same time, that it is our intention to settle these items. Our derivative positions, at fair value in the Condensed Consolidated Balance Sheets was $2,295 million at March 31, 2011 and $4,037 million at December 31, 2010. See "Collateral Received for Clearing Operations, Guarantees Issued and Credit Facilities Available," of Note 15, "Commitments, Contingencies and Guarantees," for further discussion of our guarantees on the fulfillment of these contracts and collateral received.

The following table presents the fair value of our outstanding derivative positions at March 31, 2011 and December 31, 2010 prior to netting:


	March 31, 2011				December 31, 2010

⁽²⁾	We determine the fair value of our option contracts using standard valuation models that are based on market-based observable inputs including implied volatility, interest rates and the spot price of the underlying instrument.

⁽³⁾	We determine the fair value of our future contracts based upon quoted market prices and average quoted market yields.

Resale and Repurchase Agreements, at Contract Value

Through our clearing operations in the resale and repurchase markets with NASDAQ OMX Stockholm, we are the legal counterparty for each resale and repurchase contract traded and thereby guarantee the fulfillment of each contract. We only clear these transactions once a bilateral contract between members has been entered into whereby the two members have agreed on all terms in the transaction. The resale and repurchase agreements are not used for financing purposes by NASDAQ OMX. As the legal counterparty of each transaction, NASDAQ OMX Stockholm bears the counterparty risk between the purchaser and seller in the resale and repurchase agreement.

The structure and operations for the resale and repurchase market is similar to the derivative markets for NASDAQ OMX Commodities and NASDAQ OMX Stockholm. As discussed above in "Derivative Positions, at Fair Value," NASDAQ OMX Commodities and NASDAQ OMX Stockholm are not member-owned organizations, do not maintain a guarantee fund to which members contribute and do not enforce loss sharing assessments amongst members. In addition, unlike most other clearinghouses, they do not record any margin deposits and guarantee funds in the Condensed Consolidated Balance Sheets, as all risks and rewards of collateral ownership, including interest, belongs to the counterparty. For resale and repurchase agreements, collateral is not held by NASDAQ OMX Stockholm. All resale and repurchase clearing activities are transacted under our clearing member agreements that give us the right, in the event of default, to liquidate collateral pledged between the clearing members and to offset receivables and payables with the same counterparty.

Pledged collateral, which is transferred through NASDAQ OMX Stockholm at initiation of the bilateral contract between the two clearing member counterparties, primarily consists of Swedish government debt securities. Market participants must meet certain minimum financial standards to mitigate the risk if they become unable to satisfy their obligations. In the event that one of the participants cannot fulfill its obligation to deliver or receive the underlying security at the agreed upon price, NASDAQ OMX Stockholm is required to buy or sell the security in the open market to fulfill its obligation. In order to protect itself against a price movement in the value of the underlying security, or price risk, NASDAQ OMX Stockholm requires all participants to provide additional margin as needed, which is valued on a daily basis and is maintained at a third-party custodian bank for the benefit of the clearing members and is accessible by NASDAQ OMX Stockholm in the event of default.

We record resale and repurchase agreements at contract value plus interest gross in the Condensed Consolidated Balance Sheets as a receivable pertaining to the purchasing party and a payable pertaining to the selling party. Such receivables and liabilities attributable to outstanding resale and repurchase agreements have been netted to the extent that such a legal offset right exists and, at the same time, that it is our intention to settle these items. Our resale and repurchase agreements, at contract value in the Condensed Consolidated Balance Sheets was $6,655 million at March 31, 2011 and $3,441 million at December 31, 2010. The resale and repurchase agreements are recorded at their contractual amounts plus interest which approximates fair value, as the fair value of these items is not materially sensitive to shifts in market interest rates because of the short-term nature of these instruments and/or variable interest rates or to credit risk because the resale and repurchase agreements are fully collateralized. The resale and repurchase agreements generally mature in less than 30 days. See "Collateral Received for Clearing Operations, Guarantees Issued and Credit Facilities Available," of Note 15, "Commitments, Contingencies and Guarantees," for further discussion of our guarantees on the fulfillment of these contracts and collateral received.

Financial Instruments Not Measured at Fair Value on a Recurring Basis

Some of our financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, restricted cash, receivables, net, certain other current assets, non-current restricted cash, accounts payable and accrued expenses, Section 31 fees payable to SEC, accrued personnel costs, and certain other current liabilities.

We also consider our debt obligations to be financial instruments. The fair value of our debt obligations was estimated using discounted cash flow analyses based on our assumed incremental borrowing rates for similar types of borrowing arrangements and a Black-Scholes valuation technique that is utilized to calculate the convertible option value for the 3.75% convertible notes and the 2.50% convertible senior notes. At March 31, 2011, the carrying value of our debt obligations, before the $36 million unamortized debt discount on the 2.50% convertible senior notes, was approximately $18 million less than fair value. The difference primarily relates to an increase in the fair value of the 2.50% convertible senior notes and our Term Loans as a result of changes in current market interest rates during the period, partially offset by a decrease in fair value on the 2.50% convertible senior notes due to the convertible option feature which is equivalent to a conversion price of approximately $55.13 as compared to the closing price of $25.84 at March 31, 2011. At December 31, 2010, the carrying value of our debt obligations, before the $40 million unamortized debt discount on the 2.50% convertible senior notes, was approximately $17 million less than fair value, primarily due to an increase in the fair value of the 2.50% convertible senior notes as a result of changes in current market interest rates during the period, partially offset by a decrease in fair value on the 2.50% convertible senior notes due to the convertible option feature which is equivalent to a conversion price of approximately $55.13 as compared to the closing price of $23.73 at December 31, 2010. For further discussion of our debt obligations, see Note 8, "Debt Obligations."

Derivative Financial Instruments and Hedging Activities

Derivative Financial Instruments and Hedging Activities

14. Derivative Financial Instruments and Hedging Activities

In the ordinary course of business, we may enter into various types of derivative transactions. These derivative transactions include:

•

Futures and foreign currency forward contracts which are commitments to buy or sell at a future date a financial instrument, commodity or currency at a contracted price and may be settled in cash or through delivery.

•

Interest rate swap contracts which are agreements between two parties to exchange one stream of future interest payments for another based on a specified principal amount over a set period of time.

•

Foreign currency option contracts which give the purchaser, for a fee, the right, but not the obligation, to buy or sell within a limited time a financial instrument or currency at a contracted price that may also be settled in cash, based on differentials between specified indices or prices.

NASDAQ OMX may use these derivative financial instruments to manage exposure to various market risks, primarily foreign currency exchange rate fluctuations and changes in interest rates on our variable rate debt. Such instruments are an integral component of our market risk and related asset/liability management strategy and processes.

Fair Value Hedges

Depending on market conditions, we may use foreign currency future, forward and option contracts to limit our exposure to foreign currency exchange rate fluctuations on contracted revenue streams (hedged item) relating to our Market Technology sales. When the contracted revenue streams meet the definition of a firm commitment, these derivative contracts may be designated as fair value hedges if the applicable hedge criteria are met. Changes in fair value on the derivatives and the related hedged items are recognized in the Condensed Consolidated Statements of Income. As of March 31, 2011 and December 31, 2010, there were no outstanding fair value hedges.

Cash Flow Hedges

In the third quarter of 2008, we entered into interest rate swap agreements that effectively converted $200 million of our senior secured credit facilities in place as of December 31, 2009, which was floating rate debt, to a fixed rate basis through August 2011, thus reducing the impact of interest rate changes on future interest expense. As of December 31, 2009, these interest rate swaps were in a net liability position of $9 million and were recorded in other liabilities in the Condensed Consolidated Balance Sheets. In the first quarter of 2010, in connection with the repayment of our senior secured credit facilities in place as of December 31, 2009, we terminated our interest rate swaps and reclassified into earnings the unrealized loss of $9 million which was included in accumulated other comprehensive loss in the Condensed Consolidated Balance Sheets at December 31, 2009. This loss is included in general, administrative and other expense in the Condensed Consolidated Statements of Income for the three months ended March 31, 2010. See "Senior Unsecured Notes and Credit Facility," of Note 8, "Debt Obligations," for further discussion.

All derivative contracts used to manage interest rate risk are measured at fair value and are recorded in assets or liabilities as appropriate with the offset in accumulated other comprehensive loss within NASDAQ OMX stockholders' equity in the Condensed Consolidated Balance Sheets. Any ineffectiveness would impact earnings through interest expense. There was no material ineffectiveness recorded in earnings for both the three months ended March 31, 2011 and 2010. As of March 31, 2011 and December 31, 2010, there were no outstanding cash flow hedges.

Net Investment Hedges

Net assets of our foreign subsidiaries are exposed to volatility in foreign currency exchange rates. We may utilize net investment hedges to offset the translation adjustment arising from remeasuring our investment in foreign subsidiaries. As of March 31, 2011 and December 31, 2010, there were no outstanding net investment hedges.

Derivatives Not Designated as Hedges

NASDAQ OMX may also enter into economic hedges that either do not qualify or are not designated for hedge accounting treatment. This type of hedge is undertaken when hedge accounting requirements cannot be achieved or management decides not to apply hedge accounting.

We did not enter into any material economic hedges that did not qualify or were not designated for hedge accounting during the three months ended March 31, 2011 and 2010.

Commitments, Contingencies and Guarantees	15. Commitments, Contingencies and Guarantees Collateral Received for Clearing Operations, Guarantees Issued and Credit Facilities Available *Collateral Received for Clearing Operations* Through our clearing operations in the derivative markets with NASDAQ OMX Commodities, NASDAQ OMX Stockholm and IDCG, as well as riskless principal trading at NOCC and the resale and repurchase market with NASDAQ OMX Stockholm, we are the legal counterparty for each position traded and thereby guarantee the fulfillment of each contract. The derivatives are not used by the above entities for the purpose of trading on their own behalf and the resale and repurchase agreements are not used for financing purposes by NASDAQ OMX Stockholm. The structure and operations of NASDAQ OMX Commodities and NASDAQ OMX Stockholm differ from most other clearinghouses. See "Derivative Positions, at Fair Value," and "Resale and Repurchase Agreements, at Contract Value," of Note 13, "Fair Value of Financial Instruments," for further discussion. We require market participants at NASDAQ OMX Commodities and NASDAQ OMX Stockholm to provide collateral and meet certain minimum financial standards to mitigate the risk if they become unable to satisfy their obligations. Total customer pledged collateral with NASDAQ OMX Commodities and NASDAQ OMX Stockholm was $7.2 billion at March 31, 2011 and $8.7 billion at December 31, 2010. This pledged collateral is held by a third-party custodian bank for the benefit of the clearing members and is accessible by NASDAQ OMX in the event of default. NASDAQ OMX Commodities and NASDAQ OMX Stockholm do not receive any interest on these funds as the risks and rewards of collateral ownership, including interest, belong to the counterparty. We also require market participants at IDCG and NOCC to meet certain minimum financial standards to mitigate the risk if they become unable to satisfy their obligations and to provide collateral to cover the daily margin call as needed. Customer pledged cash collateral held by IDCG and NOCC, which was $22 million at March 31, 2011 and $15 million at December 31, 2010, is included in restricted cash with an offsetting liability included in other current liabilities in the Condensed Consolidated Balance Sheets, as the risks and rewards of collateral ownership, including interest income, belong to IDCG and NOCC. Clearing member pledged cash collateral, included in IDCG's guaranty fund, was $8 million at both March 31, 2011 and December 31, 2010. This cash is included in non-current restricted cash with an offsetting liability included in other liabilities in the Condensed Consolidated Balance Sheets, as the risks and rewards of collateral ownership, including interest income, belong to IDCG. *Guarantees Issued and Credit Facilities Available* In addition to the collateral pledged by market participants discussed above, we have obtained financial guarantees and credit facilities which are guaranteed by us through counter indemnities, to provide further liquidity and default protection related to our clearing businesses. At March 31, 2011, financial guarantees issued to us totaled $6 million. Credit facilities, which are available in multiple currencies, primarily Swedish Krona and U.S. dollar, totaled $459 million ($208 million in available liquidity and $251 million to satisfy regulatory requirements), none of which was utilized at March 31, 2011. At December 31, 2010, these facilities totaled $440 million ($196 million in available liquidity and $244 million to satisfy regulatory requirements), none of which was utilized. We believe that the potential for us to be required to make payments under these arrangements is mitigated through the pledged collateral and our risk management policies. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements. Leases We lease some of our office space and equipment under non-cancelable operating leases with third parties and sublease office space to third parties. Some of our leases contain renewal options and escalation clauses based on increases in property taxes and building operating costs. Other Guarantees We have provided other guarantees as of March 31, 2011 of $21 million, primarily related to obligations for our rental and leasing contracts. In addition, for certain Market Technology contracts, we have provided performance guarantees of $6 million related to the delivery of software technology and support services. We have received financial guarantees from various financial institutions to support the above guarantees. At December 31, 2010, the total of these guarantees was $24 million. We have also provided a $25 million guarantee to our wholly-owned subsidiary NOCC to cover losses associated with customer defaults, net of any collateral posted against such losses. We believe that the potential for us to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for the above guarantees. Escrow Agreements In connection with our acquisitions of FTEN and SMARTS, we entered into escrow agreements to secure the payments of post-closing adjustments and other closing conditions. At March 31, 2011, these escrow agreements provide for future payments of $23 million in 2012. Brokerage Activities Nasdaq Execution Services and NASDAQ Options Services provide guarantees to securities clearinghouses and exchanges under their standard membership agreements, which require members to guarantee the performance of other members. If a member becomes unable to satisfy its obligations to a clearinghouses or exchange, other members would be required to meet its shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral, as well as meet certain minimum financial standards. Nasdaq Execution Services' and NASDAQ Options Services' maximum potential liability under these arrangements cannot be quantified. However, we believe that the potential for Nasdaq Execution Services and NASDAQ Options Services to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements. Litigation We may be subject to claims arising out of the conduct of our business. We are not currently a party to any litigation that we believe could have a material adverse effect on our business, financial condition, or operating results. However, from time to time, we have been threatened with, or named as a defendant in, lawsuits or involved in regulatory proceedings.

16. Segments

We manage, operate and provide our products and services in three business segments: our Market Services segment, our Issuer Services segment and our Market Technology segment.

Our Market Services segment includes our U.S. and European Transaction Services businesses and our Market Data business, which are interrelated because the Transaction Services businesses generate the quote and trade information that we sell to market participants and data distributors. Market Services also includes our Broker Services business, which offers technology and customized securities administration solutions to financial participants in the Nordic markets.

Our Issuer Services segment includes our Global Listing Services and Global Index Group businesses. The companies listed on The NASDAQ Stock Market, our Nordic and Baltic exchanges and NASDAQ OMX First North represent a diverse array of industries. This diversity of companies listed on NASDAQ OMX markets allows us to develop and license NASDAQ OMX branded indexes, associated derivatives and financial products as part of our Global Index Group. The Global Listing Services business also includes our Corporate Solutions business, which generates revenues through our shareholder, directors, newswire and other services.

Our Market Technology segment delivers technology and services to marketplaces, brokers and regulators throughout the world. Market Technology provides technology solutions for trading, clearing, settlement and information dissemination, and also offers facility management integration, surveillance solutions and advisory services.

Our management allocates resources, assesses performance and manages these businesses as three separate segments. We evaluate the performance of our segments based on several factors, of which the primary financial measure is income before income taxes. Results of individual businesses are presented based on our management accounting practices and our management structure. Certain amounts are allocated to corporate items in our management reports based on the decision that those activities should not be used to evaluate the segment's operating performance. These amounts include, but are not limited to, amounts related to mergers, strategic initiatives and financing activities. See below for further discussion.

The following table presents certain information regarding these operating segments for the three months ended March 31, 2011 and 2010.

Subsequent Events *Joint Proposal to Acquire NYSE Euronext* On April 1, 2011, NASDAQ OMX and Intercontinental Exchange, or ICE, announced they had made a joint proposal to acquire NYSE Euronext for $42.50 in cash and stock per NYSE Euronext share, or approximately $11.3 billion, based on the respective NASDAQ OMX and ICE closing share prices as of March 31, 2011. Under the terms of the proposed acquisition, NYSE Euronext stockholders would receive $14.24 in cash, plus 0.4069 of a share of NASDAQ OMX common stock and 0.1436 of a share of ICE common stock for each NYSE Euronext share. In total, NASDAQ OMX would contribute $2.121 billion in cash and approximately 108 million shares of NASDAQ common stock and assume $2.074 billion of existing NYSE Euronext debt, and ICE would contribute $1.65 billion in cash and approximately 38 million shares of ICE common stock. The proposed acquisition is conditioned on confirmatory due diligence of NYSE Euronext and would require approval from a majority of NASDAQ OMX stockholders, a majority of ICE stockholders and a majority of NYSE Euronext stockholders. As part of the proposal, ICE would acquire NYSE Euronext's European derivatives businesses and certain other entities and assets of NYSE Euronext, together with their related liabilities, and NASDAQ OMX would retain NYSE Euronext's remaining entities and assets, including the NYSE Euronext stock exchanges in New York, Paris, Brussels, Amsterdam and Lisbon, as well as its U.S. options business, together with their related liabilities. NASDAQ OMX and ICE will continue to operate as separate businesses throughout the proposed transaction and, if consummated, after its completion. NASDAQ OMX and ICE would finance the $3.8 billion cash portion of the acquisition purchase price through cash on hand and new financing commitments. Both firms have received fully committed financing in connection with the acquisition proposed April 1, 2011 from groups of leading institutions. NASDAQ OMX's commitments, from Bank of America, N.A., UBS Loan Finance LLC, Nordea Bank AB (publ) and Skandinaviska Enskilda Banken AB (publ), include a $2.25 billion term loan facility and a $750 million revolving credit facility, portions of which would be used to repay indebtedness under NASDAQ OMX's existing credit agreement. The financing commitments are subject to the satisfaction of customary conditions precedent. The repayment of debt would be financed by the cash flows of the combined companies. On April 10, 2011, NYSE Euronext's board of directors rejected the NASDAQ OMX and ICE joint proposal and stated its commitment to its existing combination agreement with Deutsche Börse AG, or Deutsche Börse. Later that same day, both NASDAQ OMX and ICE reaffirmed their interest in acquiring NYSE Euronext, citing the benefits to stockholders of all three companies. On April 19, 2011, NASDAQ OMX and ICE announced they had taken a series of steps demonstrating their commitment to pursuing their joint proposal to acquire NYSE Euronext by providing greater certainty to the NYSE Euronext board which included delivery of a proposed merger agreement to the NYSE Euronext board that is substantially consistent with the terms of the current business combination agreement with Deutsche Börse, an offer to pay a reverse termination fee of $350 million (to be split equally by NASDAQ OMX and ICE) in the event that they are unable to obtain necessary antitrust and competition approvals for the acquisition, and the receipt of fully committed financing in connection with the acquisition proposed April 1, 2011. NASDAQ OMX and ICE also agreed to share equally all break-up or termination fees paid or payable to Deutsche Börse in connection with the acquisition proposal, which are contemplated to total €250.0 million ($353.2 million based on the euro to U.S. dollar exchange rate as of March 31, 2011). On April 21, 2011, NYSE Euronext's board of directors rejected the revised proposal of NASDAQ OMX and ICE, but NASDAQ OMX and ICE again reaffirmed their proposal the same day. The NASDAQ OMX and ICE joint proposal to acquire NYSE Euronext is subject to regulatory approvals in various jurisdictions, including the United States and the European Union. On April 20, 2011, NASDAQ OMX filed a Premerger Notification and Report Form pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the rules and regulations promulgated thereunder, as amended, or the HSR Act. On April 22, 2011, NASDAQ OMX received a request for additional information and documentary material, commonly known as a "second request", from the Antitrust Division of the United States Department of Justice, or DOJ, in connection with the DOJ's review of the proposed acquisition under the HSR Act. On May 2, 2011, NASDAQ OMX and ICE announced that their boards of directors had approved their intent to commence an exchange offer to acquire all of the outstanding shares of NYSE Euronext common stock in a cash and stock transaction for the same consideration per share as discussed above. If NASDAQ OMX and ICE are successful in acquiring shares pursuant to the offer, they would consummate a second step merger as soon as possible thereafter to acquire the remaining NYSE Euronext shares for the same consideration per share.
