For each separate case below, follow the three-step process for adjusting the prepaid asset account at December 31. Assume no other adjusting entries are made during the year.

1. Prepaid Insurance. The Prepaid Insurance account has a $5,000 debit balance to start the year, and no insurance payments were made during the year. A review of insurance policies shows that $1,000 of unexpired insurance remains at its December 31 year-end.

2. Prepaid Rent. On October 1 of the current year, the company prepaid $12,000 for one year of rent for facilities being occupied from that day forward. The company debited Prepaid Rent and credited Cash for $12,000. December 31 year-end statements must be prepared.

3. Supplies. The Supplies account has a $1,000 debit balance to start the year. Supplies of $2,000 were purchased during the current year and debited to the Supplies account. A December 31 physical count shows $500 of supplies remaining.

4. Accumulated Depreciation. The company has only one plant asset (equipment) that it purchased at the start of this year. That asset had cost $38,000, had an estimated life of 10 years, and is expected to be valued at $8,000 at the end of the 10-year life.

December 31 year-end statements must be prepared.
