Accounting Policies [Abstract] |
Schedule of Depreciation and Amortization Expense Computation | Property and equipment are stated at cost less accumulated depreciation and any impairment charges. We capitalize interest as part of the cost of capital projects incurred during construction. Depreciation is computed using the straight-line method over our estimated useful lives of the assets to a residual value, as a percentage of original cost, as follows:
| Years |  | Residual Values
Ships | 30 |  | 15%
Ship improvements | 3-30 |  | 0%
Buildings and improvements | 10-40 |  | 0%
Computer hardware and software | 2-12 |  | 0%
Transportation equipment and other | 3-20 |  | 0%
Leasehold improvements, including port facilities | Shorter of the remaining lease term or related asset life (3-30) |  | 0%
