Part A A firm is contemplating shortening its credit period from 40 to 30 days and believes that, as a result of this change, its average collection period will decline from 45 to 36 days. Bad-debt expenses are expected to decrease from 3% to 2% of sales. The firm is currently selling 15,000 units but believes that as a result of the proposed change, sales will decline to 12,000 units. The sale price per unit is $66, and the variable cost per unit is $48. The firm has a required return on equal-risk investments of 25%. Evaluate this decision, and make a recommendation to the firm.
