(4) | The aggregate cost for federal income tax purposes was approximately $11.4 billion at December 31, 2019. The aggregate cost for book purposes exceeds the total gross amount of real estate assets for federal income tax purposes, principally due to purchase accounting adjustments recorded under accounting principles generally accepted in the United States of America.
[2] |
(5) | Depreciation is recognized on a straight-line basis over the estimated useful asset life, which ranges from eight to 40 years for land improvements and buildings, five years for furniture, fixtures and equipment and six months for the fair market value of residential leases.
