Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases We have entered into various capital lease arrangements to obtain property and equipment for our operations. Additionally, on occasion we have purchased property and equipment for which we have subsequently obtained capital financing under sale-leaseback transactions. These agreements are typically for three years except for building leases which are for 15 years, with interest rates ranging from 1% to 13%. The leases are secured by the underlying leased buildings and equipment. We have also entered into various non-cancelable operating lease agreements for certain of our offices, equipment, land and data centers with original lease periods expiring between 2012 and 2027. We are committed to pay a portion of the related actual operating expenses under certain of these lease agreements. Certain of these arrangements have free rent periods and/or escalating rent payment provisions, and we recognize rent expense under such arrangements on a straight-line basis. Operating lease expense totaled $50 million and $151 million for the three and nine months ended September 30, 2012, and $52 million and $171 million for the three and nine months ended September 30, 2011. Contingencies Legal Matters On March 12, 2012, Yahoo filed a lawsuit against us in the U.S. District Court for the Northern District of California, claiming that we infringe ten of Yahoo’s patents that Yahoo claimed relate to “advertising,” “social networking,” “privacy,” “customization,” and “messaging,” and on April 27, 2012 Yahoo added two patents to the lawsuit that Yahoo claims relate to “advertising.” Yahoo sought unspecified damages, a damage multiplier for alleged willful infringement, and an injunction. On April 3, 2012, we filed our answer with respect to this complaint and asserted counterclaims that Yahoo’s products infringe ten of our patents. On July 6, 2012, the parties entered into a settlement agreement resolving all claims made in the litigation. On July 9, 2012, the parties filed a stipulated dismissal of the litigation with the U.S. District Court for the Northern District of California and this litigation was dismissed on July 10, 2012. We have no payment obligations under this settlement agreement. Beginning on May 22, 2012, multiple putative class actions, derivative actions, and individual actions were filed in state and federal courts in the United States and in other jurisdictions against us, our directors, and/or certain of our officers alleging violation of securities laws or breach of fiduciary duties in connection with our IPO and seeking unspecified damages. We believe these lawsuits are without merit, and we intend to continue to vigorously defend them. On October 4, 2012, on our motion, the vast majority of the cases in the United States, along with multiple cases filed against The NASDAQ OMX Group, Inc. and The Nasdaq Stock Market LLC (collectively referred to herein as NASDAQ) alleging technical and other trading-related errors by NASDAQ in connection with our IPO, were ordered centralized for coordinated or consolidated pre-trial proceedings in the United States District Court for the Southern District of New York. In addition, the events surrounding our IPO have become the subject of various government inquiries, and we are cooperating with those inquiries. We are also party to various legal proceedings and claims which arise in the ordinary course of business. In the opinion of management, there was not at least a reasonable possibility we may have incurred a material loss, or a material loss in excess of a recorded accrual, with respect to loss contingencies relating to the matters set forth above. However, the outcome of litigation is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, if one or more of these legal matters were resolved against us in the same reporting period for amounts in excess of management’s expectations, our condensed consolidated financial statements of a particular reporting period could be materially adversely affected. Credit Facilities In February 2012, we entered into an agreement for an unsecured five-year revolving credit facility that allows us to borrow up to $5,000 million for general corporate purposes, with interest payable on the borrowed amounts set at London Interbank Offered Rate (LIBOR) plus 1.0%. Under the terms of the agreement, we are obligated to pay a commitment fee of 0.10% per annum on the daily undrawn balance. No amounts were drawn down under this credit facility as of September 30, 2012. Concurrent with our entering into the revolving credit facility, we also entered into a bridge credit facility agreement that allows us to borrow up to $3,000 million to fund tax withholding and remittance obligations related to the settlement of RSUs in connection with our IPO, with interest payable on the borrowed amounts set at LIBOR plus 1.0% and an additional 0.25% payable on drawn balances outstanding from and after the 180th day of borrowing. Any amounts outstanding under this facility will be due one year after the date we draw on the facility but no later than June 30, 2014. Under the terms of the agreement, we are obligated to pay a commitment fee of 0.10% per annum on the daily undrawn balance from and after the 90th day following the date we entered into the bridge facility. In October 2012, we amended and restated our existing bridge credit facility (the Amended and Restated Term Loan) and converted it into a three-year unsecured term loan facility that allows us to borrow up to $1,500 million. See Note 11 Subsequent Event for information on the Amended and Restated Term Loan. No amounts were drawn down under the bridge credit facility agreement as of September 30, 2012.
