C) BV drastically slowed its depreciation (amortization) of "hit* video tapes at the start of 1988. In 1987 BV depreciated its rental videotape "hits" over nine months, straight line. At the start of 1988, it switched to a method it called "36 month accelerated." The financial statements do not disclose how accelerated the curve is, but do say that the company uses 150% of straight line, computed on a monthly basis.
