OtherThanTemporaryImpairmentLossesInvestmentsAvailableforsaleSecuritiesPortionRecognizedInEarningsNetQualitativeDisclosuresMethodology	For securities with an unrealized loss, Management applies a systematic methodology in order to perform an assessment of the potential for "other-than-temporary" impairment. In the case of debt securities, investments considered for "other-than-temporary" impairment: (1) had a specified maturity or repricing date; (2) were generally expected to be redeemed at par, and (3) were expected to achieve a recovery in market value within a reasonable period of time. In addition, the Bank considers whether it intends to sell these securities or whether it will be forced to sell these securities before maturity. Equity securities are assessed for other-than-temporary impairment based on the length of time of impairment, dollar amount of the impairment and general market and financial conditions relating to specific issues. Accordingly, the impairments identified on debt and equity securities and subjected to the assessment at June 30, 2012 were deemed to be temporary and required no further adjustment to the financial statements, unless otherwise noted.

Available-for-sale, Securities in Unrealized Loss Positions, Qualitative Disclosure, Nature	The trust preferred portfolio contains the largest unrealized loss in the portfolio. At June 30, 2012 this sector contained seven securities with a fair value of $4.5 million and an unrealized loss of $1.4 million. These values are virtually unchanged from the prior year-end. Trust-preferred securities held by the Bank are single entity issues, not pooled trust preferred securities. Therefore, the impairment review of these securities is based only on the issuer and the security cannot be impaired by the performance of other issuers as if it was a pooled trust-preferred bond. All of the Bank's trust preferred securities are single issue, variable rate notes with long maturities (2027 – 2028) from companies that received money (and in some cases paid back) from the Troubled Asset Relief Program (TARP), continue to pay dividends and have raised capital. None of these bonds have suspended or missed a dividend payment. At June 30, 2012, the Bank believes it will be able to collect all interest and principal due on these bonds and no other-than-temporary-impairment charges were recorded. See the Trust Preferred Securities table for additional information.

Available-for-sale, Securities in Unrealized Loss Positions, Qualitative Disclosure, Nature	The private label mortgage backed securities (PLMBS) sector shows an unrealized loss of $304 thousand, an improvement over the $500 thousand unrealized loss at December 31, 2011. These bonds were all rated AAA at time of purchase, but have since experienced rating declines. Some have experienced increased delinquencies and defaults, while others have seen the credit support increase as the bonds paid-down. The Bank monitors the performance of the PLMBS investments on a regular basis and reviews delinquencies, default rates, credit support levels and various cash flow stress test scenarios. In determining the credit related loss, Management considers all principal past due 60 days or more as a loss. If additional principal moves beyond 60 days past due, it will also be considered a loss. As a result of the analysis on PLMBS it was determined that no impairment charges were required at June 30, 2012. The Bank has recorded $390 thousand of cumulative impairment charges on this portfolio. Management continues to monitor these securities and it is possible that additional write-downs may occur if current loss trends continue. The Bank is currently participating in a class-action lawsuit against one PLMBS servicer that centers on defective warranties and representations made as part of the underwriting process. See the PLMBS table above for additional information.
