New Accounting Standards	New Accounting Standards Balance Sheet (Topic 210), Disclosures about Offsetting Assets and Liabilities (ASU 2011-11) In December 2011, the FASB issued ASU 2011-11, which became effective for the company on January 1, 2013. The standard amends and expands disclosure requirements about offsetting and related arrangements. The company does not anticipate any impacts to its results of operations, financial position or liquidity when the guidance becomes effective. Comprehensive Income (Topic 220) Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (ASU 2013-02) The FASB issued ASU 2013-02 in February 2013. This standard became effective for the company on January 1, 2013. ASU 2013-02 changes the presentation requirements of significant reclassifications out of accumulated other comprehensive income in their entirety and their corresponding effect on net income. For other significant amounts that are not required to be reclassified in their entirety, the standard requires the company to cross-reference to related footnote disclosures. Adoption of the standard is not expected to have a significant impact on the company's financial statement presentation.

The entire disclosure for reporting accounting changes and error corrections. It includes the conveyance of information necessary for a user of the Company's financial information to understand all aspects and required disclosure information concerning all changes and error corrections reported in the Company's financial statements for the period.
