In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standard Updated (ASU) 2013-02 Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (ASU 2013-02). ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The ASU is effective for annual periods and interim periods within those periods beginning after December 15, 2012. Accordingly, the Company adopted the ASU effective January 1, 2013 and the required disclosures can be found in Note 16.
