Thompson's records reveal the following information:

1. After preparing the preliminary financial statements, Thompson decided to change the depreciation method on its office equipment from double-declining-balance to straight-line. The equipment had an original cost of $100,000 when purchased on January 1, 2018. It has a 10-year useful life and no salvage value.

2. After preparing the preliminary financial statements, Thompson discovered errors in its inventory-taking procedures that have caused inventories for the last 3 years to be incorrect, as follows.

December 31, 2018	Overstated	$12,000
December 31, 2019	Understated	$17,700
December 31, 2020	Overstated	$10,500

3. Thompson purchased equipment on January 3, 2016. It originally cost $180,000 and, for depreciation purposes, the straight-line method was chosen. The asset was originally expected to be useful for 15 years and have a zero residual value. In 2020, the decision was made to shorten the total life of this asset to 9 years and to estimate the residual value at $3,000, but the preliminary financial statements were prepared using the old estimate.

4. Thompson purchased a $36,000 insurance policy on July 1, 2018, that expires on June 30, 2022. When the preliminary financial statements were reviewed, it was discovered that the original payment had been charged to insurance expense.
