Selected Financial Information Year-over-year revenue decline. Cost of earned revenues on a Non-GAAP basis declined as a percentage of revenue due to lower fuel prices and safety and claims costs. This decline was partially offset by increased costs for labor and direct material as a percentage of revenue. G&A declined primarily from a reduction in stock-based compensation. Depreciation & amortization declined primarily from assets becoming full depreciated and asset sales. Interest expense-Non-GAAP consistent with Q3-08. Provision for income taxes-Non-GAAP increased from Q3-08. See "Regulation G Disclosure" slide for a reconciliation of Non-GAAP financial measures. Amounts may not foot due to rounding.
