The provision for income taxes relates primarily to the taxable income of the Company's taxable REIT subsidiaries. The earnings, other than in taxable REIT subsidiaries, of the Company are not generally subject to federal income taxes at the Company level due to the REIT election made by the Company.

Income taxes have been provided for on the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for the temporary differences between the financial reporting basis and the tax basis of assets and liabilities.
