Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 10—Recent Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) in January 2012 issued Accounting Standards Update (“ASU”) No. 2011-11, “Disclosures About Offsetting Assets and Liabilities”, which clarifies the scope of the new offsetting disclosures requires under ASU No. 2011-11. It is limited to (1) derivatives, (2) repurchase and reverse repurchase agreements, and (3) securities borrowing and lending transactions, that are either: offset in the statement of financial position in accordance with ASC 10, “Balance Sheet Presentment”, or ASC 815, “Derivatives and Hedging”, or subject to an enforceable master netting arrangement or similar agreement regardless of whether they are presented net in the financial statements. This ASU is effective for annual and interim reporting periods beginning on or after January 1, 2013. This guidance did not have a significant impact on the Company’s consolidated financial statements. In February 2013, the FASB issued ASU No. 2012-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income”, which requires disclosure of the effects of reclassifications out of accumulated other comprehensive income (“AOCI”) or net income line items only for those items that are reported in their entirety in net income in the period of reclassification. For AOCI reclassification items that are not reclassified in their entirety into net income, entities would then cross reference to the related note to the financial statements for additional information. Since the Company’s only AOCI item consists of unrealized gains or losses on securities available for sale, the adoption of this standard had no significant impact on the Company’s consolidated financial statements.

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.
