⁽¹⁾ The sum of the earnings per share for the four quarters may differ from annual earnings per share due to the required method of computing the weighted average shares in interim periods.

The matters which affect the comparability of the quarterly results include the following:

• Seasonality: The Company’s revenues and operating income reflect the industry’s seasonality and as a result are lower in the first and fourth quarters and higher in the second and third quarters.

• Investment income and losses: The Company’s net income reflects gains and losses related to the Company’s investments held in non-qualified retirement plans and are subject to market conditions.
