Accounting Policies [Abstract] |
Schedule of Depreciation and Amortization Expense Computation | Property and equipment are stated at cost less accumulated depreciation and any impairment charges. Depreciation is computed using the straight-line method over our estimates of useful lives and residual values, 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% or 10%
Computer hardware and software | 2-12 |  | 0% or 10%
Transportation equipment and other | 3-20 |  | 0% or 10%
Leasehold improvements, including port facilities | Shorter of the remaining lease term or related asset life (3-30) |  | 0%
