New Accounting Standards
Comprehensive Income [Text Block]	Comprehensive Income In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, Comprehensive Income, with the intention of increasing the prominence of other comprehensive income in the financial statements. The FASB has eliminated the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity and will require it be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The single statement format would include the traditional income statement and the components and total other comprehensive income as well as total comprehensive income. In the two statement approach, the first statement would be the traditional income statement which would immediately be followed by a separate statement which includes the components of other comprehensive income, total other comprehensive income and total comprehensive income. These requirements should be applied retrospectively and are effective for the first interim or annual period beginning after December 15, 2011. Adoption of this standard is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Amendments to Fair Value Measurments	Amendments to Fair Value Measurements In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurements, to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and International Financial Reporting Standards (IFRSs). The amendments explain how to measure fair value. They do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices. The amendments result in common fair value measurement and disclosure requirements in GAAP and IFRSs. Some of the amendments clarify the application of existing fair value measurement requirements and others change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. Many of the previous fair value requirements are not changed by this standard. The amendments in this standard are to be applied prospectively and are effective during interim and annual periods beginning after December 15, 2011. Adoption of this standard is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Troubled Debt Restructurings	In April 2011, the FASB issued ASU No. 2011-02, A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring, to address diversity in practice concerning determining whether a restructuring constitutes a troubled debt restructuring. This update specifies that in evaluating whether a restructuring is a troubled debt restructuring, a creditor must separately conclude both that a concession has been granted by the creditor and that the debtor is experiencing financial difficulties. Also, ASU No. 2011-02 provides clarifying guidance in determining whether a concession has been granted and whether a debtor is experiencing financial difficulties. In addition, the update precludes a creditor from using the effective interest rate test in the debtor's guidance on restructuring of payables when evaluating whether a restructuring is a troubled debt restructuring. These requirements are effective for the first interim or annual period beginning on or after June 15, 2011, and should be applied retrospectively to restructurings made during the period from the beginning of the annual period of adoption to the date of adoption. Adoption of this standard is not expected to have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Disclosure of Supplementary Pro Forma Information for Business Combinations	In December 2010, the FASB issued ASU No. 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations, to address diversity in practice concerning pro forma revenue and earnings disclosure requirements for business combinations. This update specifies that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The update also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination(s) included in the reported pro forma revenue and earnings. These requirements are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. Adoption of this standard did not have a material effect on the financial statements, results of operations or liquidity of the Corporation.
Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses	In July 2010, the FASB issued ASU No. 2010-20, Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses, to provide financial statement users with greater transparency about credit quality of financing receivables and allowance for credit losses. This update requires additional disclosures as of the end of a reporting period and additional disclosures about activity that occurs during a reporting period that will assist financial statement users in assessing credit risk exposures and evaluating the adequacy of the allowance for credit losses. The additional disclosures are required to be provided on a disaggregated basis. ASU No. 2010-20 defines two levels of disaggregation and provides additional implementation guidance to determine the appropriate level of disaggregation of information. The disclosures should facilitate evaluation of the nature of the credit risk inherent in a portfolio of financing receivables, how that risk is analyzed and assessed in arriving at the allowance for credit losses, and the changes and reasons for those changes in the allowance for credit losses. The disclosures as of the end of a reporting period were effective for interim and annual reporting periods ending on or after December 15, 2010. The disclosures about activity that occurs during a reporting period are effective for interim and annual reporting periods beginning on or after December 15, 2010 and are included in this Report. Adoption of this standard did not have a material effect on the financial statements, results of operations or liquidity of the Corporation.
