Commitments, Contingencies and Guarantees [Abstract]
Commitments, Contingencies and Guarantees	18. Commitments, Contingencies and Guarantees Guarantees Issued and Credit Facilities Available In addition to the default fund contributions and margin collateral pledged by clearing members discussed in Note 16, “Clearing Operations,” 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. Financial guarantees issued to us totaled $20 million at December 31, 2013 and $7 million at December 31, 2012. At December 31, 2013, credit facilities, which are available in multiple currencies, primarily Swedish Krona, totaled $312 million ($219 million in available liquidity and $93 million to satisfy regulatory requirements), $11 million of which was utilized. At December 31, 2012, these facilities totaled $310 million ($217 million in available liquidity and $93 million to satisfy regulatory requirements), none of which was utilized. Execution Access has a clearing arrangement with Cantor Fitzgerald. As of December 31, 2013, we have contributed $19 million of clearing deposits to Cantor Fitzgerald in connection with this clearing arrangement. These deposits are recorded in other current assets in our consolidated balance sheets. Some of the trading activity in Execution Access is cleared by Cantor Fitzgerald through FICC and the balance is cleared non-FICC. Execution Access assumes the counterparty risk of clients that do not clear through FICC. Counterparty risk of clients exists for Execution Access between the trade date and the settlement date of the individual transactions, which is one business day. All of Execution Access’ obligations under the clearing arrangement with Cantor Fitzgerald are guaranteed by NASDAQ OMX. Some of the non-FICC counterparties are required to post collateral, provide principal letters, or provide other forms of credit enhancement to Execution Access for the purpose of mitigating counterparty risk. 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 Consolidated Balance Sheets for these arrangements. Lease Commitments 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 lease agreements contain renewal options and escalation clauses based on increases in property taxes and building operating costs. Other Guarantees We have provided other guarantees of $16 million as of December 31, 2013 and $18 million at December 31, 2012. These guarantees are primarily related to obligations for our rental and leasing contracts. In addition, for certain Market Technology contracts, we have provided performance guarantees of $2 million as of December 31, 2013 and $5 million as of December 31, 2012 related to the delivery of software technology and support services. We have received financial guarantees from various financial institutions to support the above guarantees. 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 Consolidated Balance Sheets for the above guarantees. Other Commitments In connection with our acquisition of BWise, we have agreed to purchase the remaining 28% ownership interest in two separate transactions, resulting in 100% ownership by the first half of 2015. As of December 31, 2013, the estimated amount of these payments totaled $12 million. See “Acquisition of BWise,” of Note 4, “Acquisitions and Divestiture,” for further discussion. In connection with the launch of NASDAQ OMX NLX, we have entered into agreements with certain members which may require us to make payments if certain financial goals are achieved. Since these payments are not currently probable and the amount cannot be quantified as of December 31, 2013, no contingent liability is recorded in the Consolidated Balance Sheets for these payments. Voluntary Accommodation Program In connection with the initial public offering by Facebook on May 18, 2012, systems issues were experienced at the opening of trading of Facebook shares. We announced a one-time program for voluntary accommodations to qualifying members of up to $62 million, for which a liability was recorded as this program was approved by the SEC in March 2013. This program expanded the pool available for qualified losses arising directly from the system issues. In October 2013, NASDAQ OMX announced the completion of initial review by The Market Regulation Department of FINRA of all claims submitted by qualifying members. Thereafter, NASDAQ OMX informed claimants that FINRA would be conducting additional analysis with regard to one category of claims. Upon the completion of this additional analysis, the total value of valid submitted claims was determined to be $44 million. NASDAQ OMX submitted to the SEC a filing that provided a report on the administration of the voluntary accommodation program. After the filing became effective, our liability was reduced to $44 million and payment of valid claims totaling $44 million was made in the fourth quarter of 2013. Escrow Agreements In connection with our acquisitions of FTEN, Glide Technologies, and the index business of Mergent, Inc., including Indxis, we entered into escrow agreements to secure the payments of post-closing adjustments and to ensure other closing conditions. At December 31, 2013, these escrow agreements provide for future payments of $12 million and are included in other current liabilities and other non-current liabilities in the Consolidated Balance Sheets. Routing Brokerage Activities Our broker-dealer subsidiaries, 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 clearinghouse 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 Consolidated Balance Sheets for these arrangements. Litigation As previously disclosed, we became a party to several legal and regulatory proceedings in 2012 and 2013 relating to the Facebook IPO that occurred on May 18, 2012. We believe that the legal actions filed against NASDAQ OMX are without merit and intend to defend them vigorously. As described in our Annual Report on Form 10-K for the year ended December 31, 2012, we are named as a defendant in a consolidated matter captioned In re Facebook, Inc., IPO Securities and Derivative Litigation, MDL No. 2389 (S.D.N.Y.). On April 30, 2013, lead plaintiffs in the consolidated matter filed a consolidated amended complaint, naming our Chief Executive Officer and our prior Chief Information Officer as new defendants in connection with their roles in the Facebook IPO. The amended complaint alleges that each violated Section 20(a) of the Securities Exchange Act of 1934, or the Act, and Rule 10b-5, promulgated under the Act. By opinion and order entered December 16, 2013, the District Court for the Southern District of New York granted in part and denied in part our motion to dismiss the consolidated amended complaint. The court held that the doctrine of self-regulatory organization immunity bars plaintiffs’ negligence and securities laws claims to the extent they arise from our decisions not to halt trading or cancel trades on the day of the Facebook IPO, but not to the extent they arise from the design, promotion, and testing of our technology systems in advance of the IPO. The court also held that the economic loss doctrine does not bar plaintiffs’ negligence claims, and that the consolidated amended complaint pleads plaintiffs’ securities laws claims sufficiently to withstand a motion to dismiss. We are appealing the ruling on the motion to dismiss to the Second Circuit Court of Appeals. In our Quarterly Report on Form 10-Q for the period ended March 31, 2013, we identified a demand for arbitration from a member organization seeking indemnification for alleged losses associated with the Facebook IPO. On June 18, 2013, the District Court for the Southern District of New York granted a preliminary injunction enjoining the arbitration, and the member organization has appealed the order granting the injunction to the Second Circuit Court of Appeals. Also as previously disclosed, the staff of the SEC’s Division of Enforcement conducted an investigation relating to the systems issues experienced with the Facebook IPO. On May 29, 2013, the Commission accepted our offer of settlement, resolving this matter. As part of the settlement, our subsidiaries, The NASDAQ Stock Market LLC and NASDAQ Execution Services LLC, agreed to implement several measures aimed at preventing future violations of the Act and the rules and regulations promulgated thereunder. We fully implemented and provided the SEC with a certification of our compliance with these undertakings by December 31, 2013 as agreed. In addition, The NASDAQ Stock Market LLC paid a $10 million penalty to the United States Treasury. Except as disclosed above and in prior reports filed under the Act, we are not currently a party to any litigation or proceeding that we believe could have a material adverse effect on our business, consolidated 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. Tax Audits We are engaged in ongoing discussions and audits with taxing authorities on various tax matters, the resolutions of which are uncertain. Currently, there are matters that may lead to assessments, some of which may not be resolved for several years. Based on currently available information, we believe we have adequately provided for any assessments that could result from those proceedings where it is more likely than not that we will be assessed. We review our positions on these matters as they progress.

Guarantees Issued and Credit Facilities Available

In addition to the default fund contributions and margin collateral pledged by clearing members discussed in Note 16, “Clearing Operations,” 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.

Execution Access has a clearing arrangement with Cantor Fitzgerald.

Some of the non-FICC counterparties are required to post collateral, provide principal letters, or provide other forms of credit enhancement to Execution Access for the purpose of mitigating counterparty risk.

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 Consolidated Balance Sheets for these arrangements.
