Summary of significant accounting policies

Summary of Significant Accounting Policies

Effective April 1, 2013, the Company extended the useful lives of certain computers and equipment resulting from its actual historical usage, which demonstrated longer useful lives, as well as the planned use of these assets. The change was accounted for as a change in estimate and applied prospectively. For the three and nine months ended September 30, 2013, this change in accounting estimate decreased depreciation expense by approximately $9.4 million and $20.4 million or $0.01 and $0.03 per diluted share, respectively.

With the exception of the above change in estimate, there have been no material changes to the Company's significant accounting policies as compared to the accounting policies described in Note 2, Significant Accounting Policies, in Notes to Consolidated Financial Statements in Item 8 of Part II of the Annual Report on Form 10-K for the year ended December 31, 2012.

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-11, Income Taxes (Topic 740)—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) ("ASU 2013-11")to provide explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 31, 2013. The Company intends to adopt this standard prospectively in the first quarter of 2014 and the adoption will not result in a change to the tax provision. The Company does not expect a significant impact to its presentation of long-term taxes payable or its deferred tax assets.

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220)—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income ("ASU 2013-02"), which amends FASB Accounting Standards Codification ("ASC") 220, Comprehensive Income to include the reporting of reclassifications from accumulated other comprehensive income to the respective line items in net income. The Company adopted ASU 2013-02 during the first quarter of 2013 and presented the effects within the Condensed Consolidated Statements of Comprehensive Income and the accompanying notes.

In December 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210)—Disclosures About Offsetting Assets and Liabilities ("ASU 2011-11"), and in January 2013 issued ASU No. 2013-01, Balance Sheet (Topic 210)—Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities ("ASU 2013-01"). These standards create new disclosure requirements regarding the nature of an entity's rights of setoff and related arrangements associated with its derivative instruments, repurchase agreements, and securities lending transactions. Disclosures of certain instruments subject to enforceable master netting arrangements would be required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. The Company adopted these standards in the first quarter of 2013 and presented the effects in the accompanying notes.
