Asset Disposal And Impairments And Assets Held For Sale
8.   Asset Disposal and Impairments and Assets Held for Sale
 
    Due to escalating costs for dry-docking services, escalating repair and maintenance costs for aging vessels, increasing difficulty in obtaining certain replacement parts, declining marketability of certain vessels, and our strategic shift to deepwater vessels, we decided to forego dry-docking or refurbishment of certain vessels and to sell or permanently retire them from service. Consequently, we recognized gains and losses on the disposition of certain vessels, and non-cash impairment charges on the retirement of other vessels. Each asset was analyzed using an undiscounted cash flow analysis and valued at the lower of carrying value or net realizable value.
