| Additional 402(v) Disclosure [Text Block] | The dollar amounts reported represent the amount of net income (in thousands) reflected in the Company’s audited consolidated financial statements for the applicable year.Adjusted Pre-Tax Income is defined as GAAP pre-tax income adjusted to exclude the pre-tax impact from gains or losses that occur outside of the ordinary course of our business during the applicable year. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that adjusted pre-tax income is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in this table) used by the Company to link compensation actually paid to the Company’s named executive officers for the most recently completed fiscal year, to the Company’s performance. | Cumulative Total Shareholder Return (“TSR”) is calculated by dividing the sum of the cumulative amount of dividends for the measurement period (determined in accordance with Item 402(v) of SEC Regulation S-K), assuming dividend reinvestment, and the difference between the Company’s common share price at the end and the beginning of the measurement period by the Company’s common share price at the beginning of the measurement period. | |
