Such estimates include, but are not limited to, the Company's estimates in connection with leasing equipment, including residual values and depreciable lives, values of assets held for sale and other long-lived assets, provision for income tax, allowance for doubtful accounts, components of compensation, goodwill and intangible assets. Actual results could differ from those estimates.
