DEVELOPMENT [Abstract]
Development	DEVELOPMENT During the period in which a property is under development, costs associated with development (i.e., land, construction costs, interest expense, property taxes and other direct and indirect costs associated with development) are aggregated into the total capitalized costs of the property. Included in these costs are management’s estimates for the portions of internal costs (primarily personnel costs) deemed directly or indirectly related to such development activities. The internal costs are allocated to specific development properties based on construction activity. As the property becomes occupied, depreciation commences on the occupied portion of the building, and costs are capitalized only for the portion of the building that remains vacant. When the property becomes 80% occupied or one year after completion of the shell construction (whichever comes first), capitalization of development costs ceases. The properties are then transferred to real estate properties, and depreciation commences on the entire property (excluding the land).

The internal costs are allocated to specific development properties based on construction activity. As the property becomes occupied, depreciation commences on the occupied portion of the building, and costs are capitalized only for the portion of the building that remains vacant. When the property becomes 80% occupied or one year after completion of the shell construction (whichever comes first), capitalization of development costs ceases.
