Q.2 Porras Pottery Products, Inc., spends $200,000 per annum on its collection department. The company has $10 million in credit sales, its average collection period is 2.5 months, and the percentage of bad-debt losses is 4 percent. The company believes that, if it were to double its collection personnel, it could bring down the average collection period to 2 months and bad-debt losses to 3 percent. The added cost is $180,000, bringing total collection expenditures to $400,000 annually. Is the increased effort worthwhile if the before-tax opportunity cost of funds is 20 percent? If it is 10 percent?
