Comprehensive loss consists of net loss and other comprehensive loss, which includes foreign currency translation adjustments and changes in unrealized gains and losses on marketable securities available for sale. For purposes of comprehensive income disclosures, we do not record tax expense or benefits for the net changes in the foreign currency translation adjustments, as we intend to permanently reinvest all undistributed earnings of our foreign subsidiaries.
