At the time revenue is recorded, a reserve for right-of-return, discount or the cost of other privileges (i.e. advertising cost allowance) is recorded based upon the contracted obligation and historical information. Any significant return privileges (i.e. in excess of 5% of sales) for which less than 3 years of historical data exist, are fully reserved for at time of shipment. These amounts are recorded as reductions to revenue as follows: Right-of-return privileges (BPC line 0004_1240) and discounts (BPC line 0004_1250). Any estimated sales returns reserves are recorded at the sales price (BPC line 0018_1911) with an offsetting "Inventory right of return" asset (BPC line 0018_1786) at cost (the net balance sheet result is the net profit on the estimated sales returns).
