RECENT ACCOUNTING PRONOUNCEMENTS

In June 2011, the Financial Accounting Standards Board (the “FASB”) issued new accounting guidance regarding the presentation of comprehensive income. The new guidance requires the presentation of items of net income and comprehensive income in either a single continuous financial statement or in two separate but consecutive financial statements. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The adoption did not have a material effect on the company's consolidated financial statements.

In December 2011, the FASB issued new accounting guidance regarding additional disclosures for financial instruments that are offset including the gross amount of the asset and liability as well as the impact of any net amount presented in the consolidated financial statements. These provisions are effective for fiscal and interim periods beginning on or after January 1, 2013. The impact of adoption will not have a material effect on the company's consolidated financial statements.
