Peterson's management has decided to reexamine the company's short-term credit policies. The chief financial officer estimates that reducing the receivables collection period to 78 days would result in a sales decrease of 3 percent. The purchasing department reports that by reducing the payables period to 68.5 days, discounts would be available that would reduce the cost of goods by 9 percent. Initially the cash required to finance these changes would come from additional long-term debt, resulting in a debt to equity ratio of 100 percent. As an analyst: a. Determine whether Peterson's Chemicals would have been profitable if management had made these changes at the beginning of 2000. b. Determine how the ROE and ROA would have been affected.
