The dollar amounts reported in columns (c) and (e) represent the amount of CAP to Mr. Reilly, and the average CAP to our NEOs excluding Mr. Reilly, respectively, as computed in accordance with Item 402(v) of Regulation S-K.

Additional 402(v) Disclosure

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 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 the table) used by the company to link compensation actually paid to the company’s NEOs, for the most recently completed fiscal year, to company performance.
