Case 4: (20 points) Consider the following situations: (1) Your company has been offered credit terms of 4/30, net 90 days. What will be the nominal annual percentage cost of its non-free trade credit if it pays 120 days after the purchase? Assume a 365-day year. (5 points) (2) Suppose the credit terms offered to your firm by its suppliers are 2/10, net 30 days. Your firm is not taking discounts, but is paying after 25 days instead of waiting until Day 30. You point out that the nominal cost of not taking the discount and paying on Day 30 is approximately 37%. But since your firm is neither taking discounts nor paying on the due date, what is the effective annual percentage cost of its non-free trade credit, using a 365- day year? (5 points) (3) A company spends 319,600 a week to pay bills and maintains a lower cash balance limit of 65,000. The applicable interest rate is 3.26 percent and the fixed cost of transferring funds is 43. What is the optimal initial cash balance based on the BAT model? (5 points) (4) Each business day, on average, a company writes checks totalling $41,627 to pay its suppliers. The usual clearing time for these checks is 3.2 days. Meanwhile, the company is receiving payments from its customers each day, in the form of checks, totalling $59,948. These checks clear the bank in 1.5 days. Calculate the company's disbursement float, collection float, and net float. (5 points)
