asset on our consolidated balance sheets. Additionally, in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 95, Statement of Cash Flows, (“SFAS 95”) cash outflows for the acquisition of the DVD library, net of changes in related accounts payable, are classified as cash flows from investing activities on our consolidated statements of cash flows. This is inclusive of any upfront non-refundable payments required under revenue sharing agreements.

We amortize our DVDs, less estimated salvage value, on a “sum-of-the-months” accelerated basis over their estimated useful lives. The useful life of the new-release DVDs and back-catalog DVDs is estimated to be one year and three years, respectively. In estimating the useful life of our DVDs, we take into account library utilization as well as an estimate for lost or damaged DVDs.

For those direct purchase DVDs that we estimate we will sell at the end of their useful lives, a salvage value of $3.00 per DVD has been provided. For those DVDs that we do not expect to sell, no salvage value is provided. We periodically evaluate the useful lives and salvage values of our DVDs.

We also obtain content distribution rights in order to stream movies and TV episodes without commercial interruption to subscribers. We account for streaming content in accordance with SFAS No. 63, Reporting by Broadcasters (“SFAS 63”), which requires classification of streaming content as either a current or non-current asset in the consolidated balance sheets based on the estimated time of usage after certain criteria have been met, including availability of the streaming content for its first showing. We amortize our streaming content on a straight-line basis generally over the term of the related license agreements or the title’s window of availability. Cash outflows associated with the streaming content are classified as cash flows from operating activities on our consolidated statements of cash flows.

We also obtain DVD and streaming content through revenue sharing agreements with studios and distributors. We generally obtain titles for low initial cost in exchange for a commitment to share a percentage of our subscription revenues or a fee, based on utilization, over a fixed period, or the Title Term, which typically ranges from six to twelve months for each title. The initial cost may be in the form of an upfront non-refundable payment. This payment is capitalized in the content library in accordance with our DVD and streaming content policies as applicable. The initial cost may also be in the form of a prepayment of future revenue sharing obligations which is classified as prepaid revenue sharing expense. The terms of some revenue sharing agreements with studios obligate us to make minimum revenue sharing payments for certain titles. We amortize minimum revenue sharing prepayments (or accrete an amount payable to studios if the payment is due in arrears) as revenue sharing obligations are incurred. A provision for estimated shortfall, if any, on minimum revenue sharing payments is made in the period in which the shortfall becomes probable and can be reasonably estimated.
