Our Payments segment is comprised of PayPal, Bill Me Later and Zong. Our Enterprise segment, which we previously referred to as our GSI segment, consists of GSI Commerce, Inc., which we acquired in the second quarter of 2011.

We are required to comply with various regulations worldwide in order to operate our businesses, particularly our Payments business. We also partner with banks and other financial institutions in order to offer our Payments services globally.

Use of estimates

The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including those related to provisions for transaction and loan losses, legal contingencies, income taxes, revenue recognition, stock-based compensation, goodwill and the recoverability of intangible assets. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates.

Principles of consolidation and basis of presentation

The accompanying condensed financial statements are consolidated and include the financial statements of eBay Inc., our wholly and majority-owned subsidiaries and variable interest entities ("VIE") if we were the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Minority interests are recorded as a noncontrolling interest. A qualitative approach is applied to assess the consolidation requirement for VIEs. Investments in entities where we hold at least a 20% ownership interest and have the ability to exercise significant influence, but not control, over the investee are accounted for using the equity method of accounting. For such investments, our share of the investees' results of operations is included in interest and other, net and our investment balance is included in long-term investments. Investments in entities where we hold less than a 20% ownership interest are generally accounted for using the cost method of accounting, and our share of the investees' results of operations is included in our consolidated statement of income to the extent dividends are received.

These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2012.
