In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2013-02, Comprehensive Income - Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (AOCI). ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The new guidance requires an entity to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, a cross-reference to other disclosures is required to provide additional detail about those amounts. The Company adopted the provision of ASU 2013-02 in the first quarter of 2013 and the new disclosures are included in Note 9 - Supplemental Equity Information.
