New Accounting Standards	New Accounting Standards In July 2012, the FASB issued accounting guidance intended to reduce the cost and complexity of the annual impairment test for indefinite-lived intangible assets other than goodwill by providing the option of performing a qualitative assessment to determine whether future impairment testing is necessary. This guidance will be effective December 30, 2012, the beginning of the Corporation's 2013 fiscal year, with early adoption allowed. The Corporation does not expect the adoption to have a material impact on its financial statements.
