Non-GAAP Financial Measures

The Company presents the following non-GAAP financial measures on a forward-looking basis in this news release: earnings per share, excluding special items and impairment, non-recurring and other items; earnings per share, excluding special items, the impact of equity compensation expenses and impairment, non-recurring and other items; and return on equity, excluding special items. The most directly comparable forward-looking GAAP measures are earnings per share and return on equity. The Company currently expects fiscal 2006 equity compensation expense of approximately $0.35 to $0.37 per share. With the exception of this information, the Company is unable to provide a quantitative reconciliation of the forward-looking non-GAAP measures to the most directly comparable forward-looking GAAP measures because the Company cannot reliably forecast special items and impairment, non-recurring and other items, which are difficult to predict and estimate and are primarily dependent on future events. Please note that the unavailable reconciling items could significantly impact the Company’s future net earnings and cash flows.
