Investments, Debt and Equity Securities [Abstract] |
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block] | Note 5. Investment Securities The Corporation’s investment securities are classified as available-for-sale and held-to-maturity at September 30, 2014 and December 31, 2013. Investment securities available-for-sale are reported at fair value with unrealized gains or losses included in equity, net of tax. Accordingly, the carrying value of such securities reflects their fair value at the balance sheet date. Fair value is based upon either quoted market prices, or in certain cases where there is limited activity in the market for a particular instrument, assumptions are made to determine their fair value. See Note 7 of the Notes to Consolidated Financial Statements for a further discussion. Transfers of debt securities from the available-for-sale category to the held-to-maturity category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer remains in accumulated other comprehensive income and in the carrying value of the held-to-maturity investment security. Premiums or discounts on investment securities are amortized or accreted using the effective interest method over the life of the security as an adjustment of yield. Unrealized holding gains or losses that remain in accumulated other comprehensive income are amortized or accreted over the remaining life of the security as an adjustment of yield, offsetting the related amortization of the premium or accretion of the discount. The following tables present information related to the Corporation’s investment securities at September 30, 2014 and December 31, 2013.

The Corporation performs regular analysis on all its investment securities to determine whether a decline in fair value indicates that an investment is other-than-temporarily impaired in accordance with FASB ASC 320-10. FASB ASC 320-10 requires companies to record OTTI charges through earnings if they have the intent to sell, or if it is more likely than not that they will be required to sell an impaired debt security before recovery of its amortized cost basis. If the Corporation intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI is recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its estimated fair value at the balance sheet date. If the Corporation does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. The Corporation’s assessment of whether an impairment is other than temporary includes factors such as whether the issuer has defaulted on scheduled payments, announced a restructuring and/or filed for bankruptcy, has disclosed severe liquidity problems that cannot be resolved, disclosed a deteriorating financial condition or sustained significant losses. The Corporation maintains a watch list for the identification and monitoring of securities experiencing problems that require a heightened level of review. This could result from credit rating downgrades. The following table presents detailed information for each trust preferred security held by the Corporation at September 30, 2014 which has at least one rating below investment grade.

Temporarily Impaired Investments For all securities, the Corporation does not believe that the unrealized losses, which were comprised of 84 investment securities as of September 30, 2014, represent an other-than-temporary impairment. The gross unrealized losses of $1.2 million associated with U.S. Treasury and agency securities, federal agency obligations, mortgage-backed securities, corporate bonds, tax-exempt securities, asset-backed securities, mutual funds and equity securities are not considered to be other than temporary because these unrealized losses are related to changes in interest rates and do not affect the expected cash flows of the underlying collateral or issuer. Factors affecting the market price include credit risk, market risk, interest rates, economic cycles, and liquidity risk. The magnitude of any unrealized loss may be affected by the relative concentration of the Corporation’s investment in any one issuer or industry. The Corporation has established policies to reduce exposure through diversification of concentration of the investment portfolio including limits on concentrations to any one issuer. The Corporation believes the investment portfolio is prudently diversified. The decline in value is related to a change in interest rates and subsequent change in credit spreads required for these issues affecting market price. All issues are performing and are expected to continue to perform in accordance with their respective contractual terms and conditions. Short to intermediate average durations and in certain cases monthly principal payments should reduce further market value exposure to increases in rates. The Corporation evaluates all securities with unrealized losses quarterly to determine whether the loss is other than temporary. Unrealized losses in the corporate debt securities category consists primarily of senior unsecured corporate debt securities issued by large financial institutions, insurance companies and other corporate issuers and single issuer corporate trust preferred securities. None of the corporate issuers have defaulted on interest payments. The unrealized loss in equity securities consists of losses on other bank equities. The decline in fair value is due in large part to the lack of an active trading market for these securities, changes in market credit spreads and rating agency downgrades. Management concluded that these securities were not other-than-temporarily impaired at September 30, 2014. Future deterioration in the credit quality of these large financial institution issuers of TRUP debt securities could result in impairment charges in the future. In determining that the securities giving rise to the previously mentioned unrealized losses were not other-than-temporarily impaired, the Corporation evaluated the factors cited above, which the Corporation considers when assessing whether a security is other-than-temporarily impaired. In making these evaluations the Corporation must exercise considerable judgment. Accordingly there can be no assurance that the actual results will not differ from the Corporation’s judgments and that such differences may not require the future recognition of other-than-temporary impairment charges that could have a material effect on the Corporation’s financial position and results of operations. In addition, the value of, and the realization of any loss on an investment security are subject to numerous risks as cited above. The following tables indicate gross unrealized losses not recognized in income and fair value, aggregated by investment category and the length of time individual securities have been in a continuous unrealized loss position at September 30, 2014 and December 31, 2013:
