CREDIT AND INVENTORY
MANAGEMENT
Answers to Concepts Review and Critical Thinking Questions
1. a. A sight draft is a commercial draft that is payable immediately.
b. A time draft is a commercial draft that does not require immediate payment.
3. Credit costs: cost of debt, probability of default, and the cash discount
4. 1. Character: determines if a customer is willing to pay his or her debts
2. Capacity: determines if a customer is able to pay debts out of operating cash flow
5. 1. Perishability and collateral value
2. Consumer demand
3. Cost, profitability, and standardization
4. Credit risk
6. a. B: A is likely to sell for cash only, unless the product really works. If it does, then they might
b. A: Landlords have significantly greater collateral, and that collateral is not mobile.
c. A: Since A’s customers turn over inventory less frequently, they have a longer inventory
d. B: Since A’s merchandise is perishable and B’s is not, B will probably have a longer credit
e. A: Rugs are fairly standardized and they are transportable, while carpets are custom fit and
7. The three main categories of inventory are: raw material (initial inputs to the firm’s production
process), work-in-progress (partially completed products), and finished goods (products ready for
8. JIT systems reduce inventory amounts. Assuming no adverse effects on sales, inventory turnover
9. Carrying costs should be equal to order costs. Since the carrying costs are low relative to the order
10. Since the price of components can decline quickly, Dell does not have inventory which is purchased
and then declines quickly in value before it is sold. If this happens, the inventory may be sold at a
Solutions to Questions and Problems
NOTE: All end of chapter problems were solved using a spreadsheet. Many problems require multiple
steps. Due to space and readability constraints, when these intermediate steps are included in this
solutions manual, rounding may appear to have occurred. However, the final answer for each problem is
found without rounding during any step in the problem.
Basic
1. a. There are 30 days until the account is overdue. If you take the full period, you must remit:
b. There is a 1 percent discount offered, with a 10 day discount period. If you take the discount,
you will only have to remit:
c. The implicit interest is the difference between the two remittance amounts, or:
The number of days’ credit offered is:
2. The receivables turnover is:
And the average receivables are:
3. a. The average collection period is the percentage of accounts taking the discount times the
discount period, plus the percentage of accounts not taking the discount times the days until full
payment is required, so:
b. And the average daily balance is:
4. The daily sales are:
Since the average collection period is 29 days, the average accounts receivable is:
5. The interest rate for the term of the discount is:
And the interest is for:
a. The periodic interest rate is:
b. The EAR is:
c. The EAR is:
6. The receivables turnover is:
And the annual credit sales are:
7. The total sales of the firm are equal to the total credit sales since all sales are on credit, so:
The average collection period is the percentage of accounts taking the discount times the discount
period, plus the percentage of accounts not taking the discount times the days until full payment is
required, so:
And the average receivables are the credit sales divided by the receivables turnover so:
If the firm increases the cash discount, more people will pay sooner, thus lowering the average
8. The average collection period is the net credit terms plus the days overdue, so:
The receivables turnover is 365 divided by the average collection period, so:
And the average receivables are the credit sales divided by the receivables turnover so:
9. a. The cash outlay for the credit decision is the variable cost of the engine. If this is a one-time
order, the cash inflow is the present value of the sales price of the engine times one minus the
default probability. So, the NPV per unit is:
b. To find the breakeven probability of default, , we use the NPV equation from part a, set it
equal to zero, and solve for . Doing so, we get:
c. If the customer will become a repeat customer, the cash inflow changes. The cash inflow is now
one minus the default probability, times the sales price minus the variable cost. We need to use
the sales price minus the variable cost since we will have to build another engine for the
customer in one period. Additionally, this cash inflow is now a perpetuity, so the NPV under
these assumptions is:
The company should fill the order. The breakeven default probability under these assumptions
is:
d. It is assumed that if a person has paid his or her bills in the past, they will pay their bills in the
future. This implies that if someone doesn’t default when credit is first granted, then they will
10. The cost of switching is any lost sales from the existing policy plus the incremental variable costs
under the new policy, so:
The benefit of switching is a perpetuity, so the NPV of the decision to switch is:
11. The carrying costs are the average inventory times the cost of carrying an individual unit, so:
Carrying costs = (1,860 / 2)($6.25) = $5,812.50
The order costs are the number of orders times the cost of an order, so:
The firm’s policy is not optimal, since the carrying costs and the order costs are not equal. The
12. The carrying costs are the average inventory times the cost of carrying an individual unit, so:
The number of orders per year will be the total units sold per year divided by the EOQ, so:
Intermediate
13. The total carrying costs are:
Carrying costs = (Q / 2) CC
where CC is the carrying cost per unit. The restocking costs are:
14. The cash flow from either policy is:
Cash flow = (P – v)Q
So, the cash flows from the old policy are:
So, the incremental cash flow would be:
Incremental cash flow = $177,815 – 163,590
Incremental cash flow = $14,225
The incremental cash flow is a perpetuity. The cost of initiating the new policy is:
