Described below are six independent and unrelated situations involving accounting changes. Each change occurs during 2021 before any adjusting entries or closing entries were prepared. Assume the tax rate for each company is 25% in all years. Any tax effects should be adjusted through the deferred tax liability account. a. Fleming Home Products introduced a new line of commercial awnings in 2020 that carry a one-year warranty against manufacturer's defects. Based on industry experience, warranty costs were expected to approximate 3% of sales. Sales of the awnings in 2020 were $3,800,000. Accordingly, warranty expense and a warranty liability of $114,000 were recorded in 2020. In late 2021, the company's claims experience was evaluated, and it was determined that claims were far fewer than expected: 2% of sales rather than 3%. Sales of the awnings in 2021 were $4,300,000, and warranty expenditures in 2021 totaled $97,825. b. On December 30, 2017, Rival Industries acquired its office building at a cost of $1,060,000. It was depreciated on a straight-line basis assuming a useful life of 40 years and no salvage value. However, plans were finalized in 2021 to relocate the company headquarters at the end of 2025. The vacated office building will have a salvage value at that time of $730,000.
