Tabular List [Table Text Block] | Financial Performance Measures As described in greater detail in the “Compensation Discussion and Analysis” section above, the Company’s executive compensation program reflects a variable pay-for-performance philosophy.

The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s named executive officers, for the most recently completed fiscal year, to the Company’s performance are as follows: • Core Diluted Earnings per Share, as Adjusted ​ • Adjusted Efficiency Ratio, as Adjusted ​ • Core Return on Average Assets Ranking ​ • Core Return on Tangible Common Equity Ranking ​ • Total Shareholder Return Ranking |  |
