Recent Accounting Pronouncements	On June 16, 2011, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”), which revises the manner in which entities present comprehensive income in their financial statements. The new guidance requires companies to report components of comprehensive income in either: (1) a continuous statement of comprehensive income; or (2) two separate consecutive statements. In addition, in December 2011, the FASB issued an amendment which defers the requirement to present components of reclassifications of other comprehensive income on the face of the income statement. ASU 2011-05 does not change the items that must be reported in other comprehensive income. The Company adopted ASU 2011-05 in the first quarter of fiscal 2013 by reporting a separate statement of comprehensive loss.
