Mary Company implemented the following accounting changes in 2020: 1. During 2020 it became apparent that increased demand for products would force the company to replace its equipment earlier than originally anticipated. The equipment was purchased on January 1, 2018 for $100,000. At that time the expected economic life, which is equal to the expected useful life, was 10 years and salvage value was estimated at $20,000. Now, management is convinced the equipment will be disposed of on December 31, 2022, for $3,000. No amortization has been recorded in 2020 for this equipment. 2. It was discovered that a patent was being amortized over its legal life of 17 years, instead of its useful life of 5 years. The patent was purchased on January 1, 2018, for $25,000. 3. The company decided to change its inventory value method from FIFO to Weighted average. Under FIFO, beginning and ending inventory for 2020 would have been $12,000 and $16,000, respectively. Under Weighted-average, the ending inventory is valued at $13,000. Unfortunately, the existing records do not allow the re- ye, the ending inventory is valued at $13,000.
