Shocks Ltd sells shock absorbers to mechanical workshops on credit only. The management of the company estimated that it could increase sales by offering better credit terms. Currently, the days sales outstanding (or average collection period) is 12 days. It is expected that this will change to 30 days under the new standards. Sales are expected to increase from R120 million to R180 million. No discounts are offered and bad debts are currently 1% of the sales, but the company expects it to increase to 3% under the new terms. The company can borrow short-term funds at a rate of 7%, invest at the same rate and has a gross profit margin of 15%. Determine whether it would be worthwhile for the company to change its credit terms. Note: Show only the change in gross profit, the change in bad debts, the change in the cost of carrying receivables and the final effect on net profit. Also indicate whether would be worthwhile to change the credit standards or not
