Inventories. The costs of feature films and television programs, including production advances to independent producers, interest on production loans, and distribution advances to film licensors, are amortized on bases designed to write off costs in proportion to the expected flow of income. The cost of general release feature productions is divided between theatrical ion and television ion, based on the proportion of net revenues expected to be derived from each source. The portion of the cost of feature productions allocated to theatrical ion is amortized generally by the application of tables which write off approximately 62% in 26 weeks, 85% in 52 weeks, and 100% in 104 weeks after release. Costs of two theatrical productions first released on a reserved-seat basis are amortized in the proportion that rentals earned bear to the estimated final theatrical and television rentals. Because of the depressed market for the licensing of feature films to television and poor acceptance by the public of a number of theatrical films released late in the year, the company made a special provision for additional amortization of recent releases and those not yet licensed for television to reduce such films to their currently estimated net realizable values.
