| Pay vs Performance [Table Text Block] | Pay Versus Performance Table The following table shows compensation actually paid by year, compared to amounts in the Summary Compensation Table. In addition to the cash actually paid, the compensation actually paid reflects: a. The year-end fair value of any equity awards granted during the year that are outstanding and unvested as of the end of the year. b. The amount of change as of the end of the current year from the end of the prior year in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the current year. c. For awards granted in prior years that vest in the current year, the amount equal to the change as of the vesting date, from the end of the prior year in fair value.

ROA and net income are also components of the “Balanced Scorecard: CEO Performance Matrix” in the financial metrics to budget comparison. While there is generally a direct relationship between these factors and the amount of compensation actually paid, final compensation paid is also impacted by the other criteria in the balanced scorecard. Additionally, based on progress over multi-year periods, amounts paid are intended to motivate management to further achieve longer-term financial goals that are disclosed on the Company’s website. The Compensation Committee also compares total shareholder return and return on assets (which incorporates net income) of the Company to its proxy peer group in its determination of compensation which is also a component of the balanced scorecard. A more qualitative analysis is necessitated by considering financial performance being achieved versus risk associated with that performance. Such risk could negatively impact financial performance in the future after compensation has already been paid. These risks include credit, compliance, and regulatory risk. Assessment of these risks is also included in the balanced score card. The amount actually paid to the CEO in the pay for performance table reflected the appreciation in the stock price, which was consistent with the Compensation Committee’s intention to motivate management toward multiple year sustained financial progress and resulting shareholder returns. NEO compensation actually paid is also directly related to total shareholder return, net income, and ROA. While the NEOs’ roles within each of these criteria vary, their performance directly impacts financial measures. However, independent of those financial measures, compensation actually paid may reflect individual performance and achievements not adequately reflected in those measures. | ||
