Accounting Policy
We have significant capital invested in our long-lived assets, and judgments are made in determining their estimated useful lives and salvage values and if or when an asset (or asset group) has been impaired. The accuracy of these estimates affects the amount of depreciation and amortization expense recognized in our financial results and whether we have a gain or loss on the disposal of an asset. We assign lives to our assets based on our standard policy, which is established by management as representative of the useful life of each category of asset.
We review the carrying value of our long-lived assets whenever events and circumstances indicate that the carrying value of an asset may not be recoverable from the estimated future cash flows expected to result from its use and eventual disposition. We typically estimate the fair value of assets starting with a “Replacement Cost New” approach and then deduct appropriate amounts for both functional and economic obsolescence to arrive at the fair value estimates. Other factors considered by management in performing this assessment may include current operating results, trends, prospects, and third-party appraisals, as well as the effect of demand, competition, and other economic, legal, and regulatory factors. In estimating expected future cash flows for determining whether an asset is impaired, assets are grouped at the lowest level of identifiable cash flows, which, for most of our assets, is the individual property. These analyses are sensitive to management assumptions and the estimates of the obsolescence factors. Changes in these assumptions and estimates could have a material impact on the analyses and the consolidated financial statements.
Additions to property and equipment are stated at cost. We capitalize the costs of improvements that extend the life of the asset. We expense maintenance and repair costs as incurred. Gains or losses on the dispositions of property and equipment are recognized in the period of disposal. Interest expense is capitalized on internally constructed assets at the applicable weighted-average borrowing rates of interest. Capitalization of interest ceases when the project is substantially complete or construction activity is suspended for more than a brief period of time. Interest capitalized was $45 million, $38 million, and $38 million for the years ended December 31, 2014, 2013, and 2012, respectively.
Depreciation is calculated using the straight-line method over the shorter of the estimated useful life of the asset or the related lease as follows:
Useful Lives
Land improvements
12 years
Buildings
20 to 40 years
Leasehold improvements
5 to 15 years
Riverboats and barges
30 years
Furniture, fixtures, and equipment
2 to 20 years
