Critical Accounting Policies [Abstract]
Critical Accounting Policies [Text Block]	Critical Accounting Policies Management has identified its most critical accounting policies to be those related to asset impairment judgments, including fair value and OTTI of available for sale investment securities, the valuation of other real estate owned and the allowance for loan losses. Securities available for sale are reported at fair value, with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of deferred income taxes. The Company evaluates each of its investment securities whose value has declined below amortized cost to determine whether the decline in fair value is OTTI. The investment portfolio is evaluated for OTTI by segregating the portfolio into two segments and applying the appropriate OTTI model. Investment securities classified as available for sale are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities. However, certain purchased beneficial interests in securitized financial assets, including asset-backed securities and collateralized debt obligations that had credit ratings below AA at the time of purchase, are evaluated using the model outlined in FASB ASC 325, Beneficial Interests in Securitized Financial Assets. In determining OTTI under the FASB ASC 320 model, the review takes into consideration the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer and other qualitative factors, as well as whether the Company intends to sell the security or whether it is more likely than not the Company will be required to sell the debt security before its anticipated recovery. Under the FASB ASC 325 model for the second segment of the portfolio, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell or it is more likely than not that 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 fair value at the balance sheet date. If the Company does not intend to sell the security and it is not more likely than not that the entity will be required to sell 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 total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, using the original yield as the discount rate, 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 assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at the time. Other real estate owned includes real estate properties acquired through or in lieu of foreclosure. Properties are initially recorded at fair value less estimated selling costs at the date of foreclosure, thus establishing a new cost basis. Fair value is determined by management by obtaining appraisals or other market value information at least annually. Any write-downs in value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management by obtaining updated appraisals or other market information. Any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the updated fair value less estimated selling cost. Net costs related to the holding of properties are included in noninterest expense. The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely. The Company has policies and procedures for evaluating the overall credit quality of its loan portfolio, including timely identification of potential problem loans. On a quarterly basis, management reviews the appropriate level for the allowance for loan losses, incorporating a variety of risk considerations, both quantitative and qualitative. Quantitative factors include the Company's historical loss experience, delinquency and charge-off trends, collateral values, known information about individual loans and other factors. Qualitative factors include the general economic environment in the Company's market areas and the expected trend of those economic conditions. While management uses the best information available to make its evaluations, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon. To the extent actual results differ from forecasts and management's judgment, the allowance for loan losses may be greater or less than future charge-offs.

Critical Accounting Policies

Management has identified its most critical accounting policies to be those related to asset impairment judgments, including fair value and OTTI of available for sale investment securities, the valuation of other real estate owned and the allowance for loan losses.

Securities available for sale are reported at fair value, with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of deferred income taxes. The Company evaluates each of its investment securities whose value has declined below amortized cost to determine whether the decline in fair value is OTTI. The investment portfolio is evaluated for OTTI by segregating the portfolio into two segments and applying the appropriate OTTI model. Investment securities classified as available for sale are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities. However, certain purchased beneficial interests in securitized financial assets, including asset-backed securities and collateralized debt obligations that had credit ratings below AA at the time of purchase, are evaluated using the model outlined in FASB ASC 325, Beneficial Interests in Securitized Financial Assets.

In determining OTTI under the FASB ASC 320 model, the review takes into consideration the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer and other qualitative factors, as well as whether the Company intends to sell the security or whether it is more likely than not the Company will be required to sell the debt security before its anticipated recovery.

An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.

When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell or it is more likely than not that 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 fair value at the balance sheet date.

Net costs related to the holding of properties are included in noninterest expense.

The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely. The Company has policies and procedures for evaluating the overall credit quality of its loan portfolio, including timely identification of potential problem loans. On a quarterly basis, management reviews the appropriate level for the allowance for loan losses, incorporating a variety of risk considerations, both quantitative and qualitative.
