Under ASU 2013-02, an entity is required to provide information about the amounts reclassified out of Accumulated other comprehensive income, or AOCI, by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective for interim and annual periods beginning after December 15, 2012 and early adoption is permitted. We early adopted ASU 2013-02 for the annual period ended December 31, 2012. The adoption of ASU 2013-02 has not had a material impact on our consolidated financial condition or results of operations taken as a whole. In January 2013, the FASB issued ASU, No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 clarifies that the scope of ASU 2011-11, Disclosures about Offsetting Assets and Liabilities, would apply to derivatives accounted for in accordance with FASB ASC 815, Derivatives and Hedging, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with ASC 210-20-45 or ASC 815-10-45 or subject to an enforceable master netting arrangement or similar agreement. This ASU is effective for fiscal years beginning on or after January 1, 2013 and interim periods within those annual periods. We adopted ASU 2013-01 during the period ended March 31, 2013. The adoption of ASU 2013-01 has not had a material impact on our consolidated financial condition or results of operations taken as a whole. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This ASU allows an entity the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. ASU 2011-05 is applied retrospectively. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We adopted ASU 2011-05 during the reporting period ended December 31, 2011, and this changed the presentation of our financial statements but not our consolidated financial condition or results of operations taken as a whole. In November 2011, the FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05.

The effective dates and changes to our presentation are the same as noted in ASU 2011-05 above. In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. The amendments change the wording, mainly for clarification, used to describe many of the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. For many of the requirements, the Board does not intend for the amendments in this update to result in a change in the application of the requirements in ASU 2011-04. The amendments in this ASU are to be applied prospectively. The amendments are effective during interim and annual periods beginning after December 15, 2011. We adopted ASU 2011-04 for the interim and annual periods of fiscal year 2012. The adoption of ASU 2011-04 has not had a material impact on our consolidated financial condition or results of operations taken as a whole.
