SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements include the accounts of Affymetrix, Inc. and its wholly-owned subsidiaries (“Affymetrix” or the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments, consisting of normal recurring entries, considered necessary for a fair presentation have been included.

Interim financial results are not necessarily indicative of results anticipated for the full year. These unaudited financial statements should be read in conjunction with the Company's audited financial statements and footnotes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013, from which the balance sheet information as of that date and as included herein was derived.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, and related disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

There have been no material changes to the Company’s significant accounting policies as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of net loss and other comprehensive income (loss) (“OCI”). OCI includes foreign currency translation adjustments, unrealized gains and losses on the Company's non-marketable securities that are excluded from net loss and unrealized gains and losses on cash flow hedges. Total comprehensive loss has been disclosed in the Company's Condensed Consolidated Statements of Comprehensive Loss.

The following table summarizes the amounts reclassified out of accumulated other comprehensive income, net of tax, for the three months ended March 31, 2014 (in thousands):
