Art Angel operated a small seasonal lake marina, renting boats and selling snacks. He rents marina space for four months in Year 2004, from May 15 to September 15, for $800 per month. He started the current season with $15,000 in the bank and paid the marina seasonal rent in advance. In May, he bought three new boats for cash at $12,500 each and borrowed $25,000 at 6 percent interest. The new boats are estimated to have a 10-season life and a residual (trade-in) value of $2,500 each.

Straight-line depreciation will be used.

No food or beverage inventory remained at season end. Other costs incurred during the season were boat maintenance, $1,211, and casual labor costs, $1,440. He paid the interest for the year based on the amount of the loan outstanding on May 15 and repaid $10,000 of the loan. In addition, Art said he withdrew $2,000 per month during the season. The season-ending cash balance in the bank is $14,697. No records exist regarding the amount of cash sales.
