Computers Galore Ltd. sells computers, computer accessories, and software. On its computer sales, the company provides a one-month warranty that is included in the cost of the computer. Claims under the warranties vary from replacing defective items to providing customers with refunds if they choose. During 2020, the estimated costs related to the one-month warranties was $39,600, of which $35,000 had been incurred before year end ($30,700 for replacement items and $4,300 in refunds). For an additional charge of $100, Computers Galore also offers extended warranty coverage for two years on its computers. This amount is expected to cover the costs associated with the extended warranties. During 2020, Computers Galore sold 700 two-year warranties.

Based on experience, the company estimates that its total warranty costs over the two-year coverage period will be $70,000, which it expects will occur evenly over the warranty period.
