summary of significant accounting policies revenues and expenses deposits received on sales of passenger cruises are initially recorded as customer deposit liabilities on our balance sheet .
customer deposits are subsequently recognized as passenger ticket revenues , together with revenues from onboard and other goods and services and all associated direct costs of a voyage , upon completion of voyages with durations of ten days or less , and on a pro-rata basis for voyages in excess of ten days .
revenues and expenses include port costs that vary with guest head counts .
the amounts of such port costs included in passenger ticket revenues on a gross basis were $ 459.8 million , $ 442.9 million and $ 398.0 million for the years 2012 , 2011 and 2010 , respectively .
cash and cash equivalents cash and cash equivalents include cash and market- able securities with original maturities of less than 90 days .
inventories inventories consist of provisions , supplies and fuel carried at the lower of cost ( weighted-average ) or market .
property and equipment property and equipment are stated at cost less accu- mulated depreciation and amortization .
we capitalize interest as part of the cost of acquiring certain assets .
improvement costs that we believe add value to our ships are capitalized as additions to the ship and depreciated over the shorter of the improvements 2019 estimated useful lives or that of the associated ship .
the estimated cost and accumulated depreciation of replaced or refurbished ship components are written off and any resulting losses are recognized in cruise operating expenses .
liquidated damages received from shipyards as a result of the late delivery of a new ship are recorded as reductions to the cost basis of the ship .
depreciation of property and equipment is computed using the straight-line method over the estimated useful life of the asset .
the useful lives of our ships are generally 30 years , net of a 15% ( 15 % ) projected residual value .
the 30-year useful life of our newly constructed ships and 15% ( 15 % ) associated residual value are both based on the weighted-average of all major components of a ship .
depreciation for assets under capital leases is computed using the shorter of the lease term or related asset life .
( see note 5 .
