Event or Decision	A	B	C	D
1. As a result of a production improvement, Carolina determined that manufacturing equipment previously depreciated over 15 years should be depreciated over 20 years.

2. The equipment that Carolina manufactures is sold with a 5-year warranty. This warranty cannot be purchased separately by customers. Because of a production breakthrough, Carolina reduced its computation of warranty costs from 3% of sales to 1% of sales.

3. Carolina changed from LIFO to FIFO to account for its finished goods inventory.
4. Carolina changed from FIFO to average cost to account for its raw materials and work-in-process inventories.
5. Carolina sells extended service contracts on its products. Because related services are performed over several years, in Year 9 Carolina changed from the cash method to the accrual method of recognizing income from these service contracts.
6. During Year 9, Carolina determined that an insurance premium paid and entirely expensed in Year 7 was for the period January 1, Year 7, through January 1, Year 9.
7. Carolina changed its method of depreciating office equipment from an accelerated method to the straight-line method to reflect costs more accurately in the later years of the useful life.
8. Carolina instituted a pension plan for all employees in Year 9 and adopted the relevant GAAP. Carolina had not previously had a pension plan.
