16. Level versus seasonal production (LO5) Wisconsin Snowmobile Corp. is considering a
switch to level production. Cost efficiencies would occur under level production, and
aftertax costs would decline by $36,000, but inventory would increase by $300,000.
Wisconsin Snowmobile has to finance the extra inventory at a cost of 13.5 percent.
a. Determine the extra cost or savings of switching over to level production. Should the
company go ahead and switch to level production?
b. How low would interest rates need to fall before level production would be feasible?
7-16. Solution:
Wisconsin Snowmobile Corporation
a. Inventory increases by $300,000
Don’t switch to level production.
b. If interest rates fall to 12 percent or less, the switch would be
feasible.
$36,000 Savings 12%
$300,000 Increased inventory =
However, the decision is more complicated because it depends on
expectations for interest rates. If the extra inventory were considered
permanent current assets and was financed by locking in long-term
17. Credit policy decision (LO4) Johnson Electronics is considering extending trade credit to
some customers previously considered poor risks. Sales would increase by $150,000 if credit
is extended to these new customers. Of the new accounts receivable generated, 5 percent will
prove to be uncollectible. Additional collection costs will be 2 percent of sales, and production
and selling costs will be 74 percent of sales. The firm is in the 35 percent tax bracket.
a. Compute the incremental income after taxes.
b. What will Johnson’s incremental return on sales be if these new credit customers are
accepted?
c. If the receivable turnover ratio is 3 to 1, and no other asset buildup is needed to serve
the new customers, what will Johnson’s incremental return on new average
investment be?
7-17. Solution:
Johnson Electronics
a. Additional sales................................................... $150,000
Accounts uncollectible (5% of new sales)........... – 7,500
Annual incremental revenue................................ $ 142,500

18. Credit policy decision-receivables and inventory (LO4 and 5) Henderson Office Supply
is considering a more liberal credit policy to increase sales, but expects that 9 percent of the
new accounts will be uncollectible. Collection costs are 6 percent of new sales, production
and selling costs are 74 percent, and accounts receivable turnover is four times. Assume
income taxes of 20 percent and an increase in sales of $65,000. No other asset buildup will
be required to service the new accounts.
a. What is the level of accounts receivable to support this sales expansion?
b. What would be Henderson’s incremental aftertax return on investment?
c. Should Henderson liberalize credit if a 16 percent aftertax return on investment is
required?
Assume that Henderson also needs to increase its level of inventory to support new sales and
that inventory turnover is two times.
d. What would be the total incremental investment in accounts receivable and inventory
to support a $65,000 increase in sales?
e. Given the income determined in part b and the investment determined in part d,
should Henderson extend more liberal credit terms?

19. Credit policy decision with changing variables (LO4) Fast Turnstiles Co. is evaluating
the extension of credit to a new group of customers. Although these customers will provide
$180,000 in additional credit sales, 12 percent are likely to be uncollectible. The company
will also incur $16,200 in additional collection expense. Production and marketing costs
represent 72 percent of sales. The firm is in a 34 percent tax bracket and has a receivables
turnover of four times. No other asset buildup will be required to service the new
customers. The firm has a 10 percent desired return.
a. Calculate the incremental income after taxes and the return on incremental
investment. Should Fast Turnstiles Co. extend credit to these customers?
b. Calculate the incremental income after taxes and the return on incremental investment
if 15 percent of the new sales prove to be uncollectible. Should credit be extended if
15 percent of the new sales prove uncollectible?
c. Calculate the return on incremental investment if the receivables turnover drops to
1.6, and 12 percent of the accounts are uncollectible. Should credit be extended if the
receivables turnover drops to 1.6, and 12 percent of the accounts are uncollectible (as
in part a)?
7-19. Solution:
Fast Turnstiles Co.
a. Added sales........................................................... $180,000
Accounts uncollectible (12% of new sales)............ 21,600
Incremental income after taxes............................ $ 4,752
$4,752
Return on incremental investment 10.56%
$45,000
= =
Yes, extend credit.
c. If receivable turnover drops to 1.6x, the investment in
accounts receivable would equal $180,000/1.6 = $112,500.
$8,316
Return on incremental investment 7.39%
$112,500
= =
Credit should not be extended because 7.39 percent is less
than the desired 10 percent.
20. Credit policy decision with changing variables (LO4) Slow Roll Drum Co. is evaluating
the extension of credit to a new group of customers. Although these customers will provide
$180,000 in additional credit sales, 12 percent are likely to be uncollectible. The company
will also incur $16,200 in additional collection expense. Production and marketing costs
represent 72 percent of sales. The firm is in a 34 percent tax bracket. No other asset buildup
will be required to service the new customers. The firm has a 10 percent desired return.
Assume the average collection period is 120 days.
a. Compute the return on incremental investment
b. Should credit be extended?
