OB1 Sabres Ltd. has determined that product sales are not what they could be because they have unused capacity. As a result, the company is considering adjusting its marketing strategy. At present, all sales to distributors are on a cash basis, but the competition offers credit terms. Similar credit terms for OB1 Sabres have been suggested. Research suggests that sales in the upcoming year would jump from $4.38 million annually to $5.66 million with credit terms of 3/10, net 30. Furthermore, research estimates that 75 percent of the customers would take the discount and the remainder would pay on average on the 30th day. Inventory turnover would remain at 12 times a year. Cost of goods sold (variable costs) are 75 percent of gross sales Bad debts are estimated to be 075 percent of credit sales. Credit department expenses would be $51,600 per year plus the salary of 2 individuals at $36,600 per year each. One of the staff would be reassigned from another division without affecting costs or productivity as that individual is currently redundant in that division Marketing expenses are 4 percent of gross sales. Bank financing of working capital requirements is at 11 percent. a. Should B1 Sabres Ltd. adopt the proposed policy? O Yes FONO b. Show the calculations. (Use 365 days in a year.
