At the beginning of 2013, Scarlet Industries began offering a three-year  warranty on its products. The warranty program was expected to cost Scarlet 2% of net sales, approximately equally over the three-year warranty period. Net sales made under warranty in 2013 were $270 million. Thirteen percent of the units sold were returned in 2013 and repaired or replaced at a cost of $2 million. This amount was debited to warranty expense as incurred.
