Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income	During February 2013, the Financial Accounting Standards Board (“FASB”) issued ASU 2013-02: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income. For other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. The Company adopted ASU 2013-02 beginning with the first quarter of fiscal 2013. There was no impact on the Company’s financial statements during the first six months of fiscal 2013, and we do not anticipate ASU 2013-02 having a material impact on the Company’s financial statements during the remainder of fiscal 2013.
Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists	In July 2013, the Financial Accounting Standards Board issued ASU No. 2013-11: Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires unrecognized tax benefits to be presented as a decrease in a net operating loss, similar tax loss or tax credit carryforward if certain criteria are met. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU 2013-11 is not expected to have a material impact on the Company’s consolidated financial statements during the remainder of fiscal 2013.
