After Studying Chapter 10, you should be able to: 1. 2. 3. 4. 5. 6. 10. 2 List the key factors that can be varied in a firm's credit policy and understand the trade-off between profitability and costs involved. Understand how the level of investment in accounts receivable is affected by the firm's credit policies. Critically evaluate proposed changes in credit policy, including changes in credit standards, credit period, and cash discount. Describe possible sources of information on credit applicants and how you might use the information to analyze a credit applicant. Identify the various types of inventories and discuss the advantages and disadvantages of increasing/decreasing inventories Describe, explain, and illustrate the key concepts and calculations necessary for effective inventory management and control, including classification, economic order quantity (EOQ), order point, safety stock, and just-in-time (JIT).

Credit Standards – The minimum quality of credit worthiness of a credit applicant that is acceptable to the firm. Why lower the firm’s credit standards? The financial manager should continually lower the firm’s credit standards as long as profitability from the change exceeds the extra costs generated by the additional receivables. 10. 5 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Example of Relaxing Credit Standards • Additional annual credit sales of $120, 000 and an average collection period for new accounts of 3 months is expected. • The before-tax opportunity cost for each dollar of funds “tied-up” in additional receivables is 20%. Ignoring any additional bad-debt losses that may arise, should Basket Wonders relax their credit standards? 10. 8 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Credit Terms – Specify the length of time over which credit is extended to a customer and the discount, if any, given for early payment. For example, “ 2/10, net 30. ” Credit Period – The total length of time over which credit is extended to a customer to pay a bill. For example, “net 30” requires full payment to the firm within 30 days from the invoice date. 10. 13 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Changing credit standards u u 10. 18 Li Hong Company is currently selling a product for $10 per unit. Sales (all on credit) for last year were 60, 000 units. The variable cost per unit is $6. The firm’s total fixed costs are $120, 000. The firm is considering a relaxation of credit standards that is expected to result in the following: a 5% increase in unit sales to 63, 000 units; an increase in the average collection period from 30 days (its current level) to 45 days; an increase in bad-debt expenses from 1% of sales (the current level) to 2%. The firm’s required return on equal-risk investments, which is the opportunity cost of tying up funds in accounts receivable, is 15%.

Changing credit standards u u u 10. 19 Need to calculate the effect on the firm’s additional profit contribution from sales, the cost of the marginal investment in accounts receivable and the cost of marginal bad debts. Additional profit contribution from sales Fixed costs are ‘sunk’ and thereby unaffected by a change in the sales level. Variable cost is the only cost relevant to a change in sales. Sales are expected to increase by 5%, or 3, 000 units. The profit contribution per unit equals the difference between the sale price per unit ($10) and the variable cost per unit ($6) and so the profit contribution per unit will be $4. Thus, the total additional profit contribution from sales will be $12, 000 (3, 000 units × $4 per unit).

Changing credit standards u u u 10. 20 Cost of the marginal investment in accounts receivable To determine the cost of the marginal investment in accounts receivable, Peng Xi must find the difference between the cost of carrying receivables before and after the introduction of the relaxed credit standards. We are only concerned about the outof-pocket costs so the relevant cost in this analysis is the variable cost. The average investment in accounts receivable can be calculated using the following formula: Average investment in accounts receivable = total variable cost of annual sales/ turnover of accounts receivable where Turnover of accounts receivable = 365/average collection period Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
Changing credit standards u u u u u 10. 21 The total variable cost of annual sales, using the variable cost per unit of $6 are, Total variable cost of annual sales: Under present plan: ($6 × 60, 000 units) = $360, 000 Under proposed plan: ($6 × 63, 000 units) = $378, 000 The proposed plan increases total variable cost of sales by $18, 000. The turnover of accounts receivable shows the number of times each year that accounts receivable are turned into cash. It is found by dividing the average collection period into 365. Turnover of accounts receivable (rounded): Under present plan: 365/30 = 12. 2 Under proposed plan: 365/45 = 8. 1 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Changing credit standards u u u 10. 22 Substitute the cost and turnover data just calculated to get the following average investments in accounts receivable: Average investment in accounts receivable: Under present plan: $360, 000/12. 2 = $29, 508 Under proposed plan: $378, 000/8. 1 = $46, 667 The marginal investment in accounts receivable, and its cost, are calculated as follows: Cost of marginal investment in accounts receivable (A/R): Average investment under proposed plan $46, 667 – Average investment under present plan 29, 508 Marginal investment in accounts receivable $17, 159 × Required return on investment 0. 15 Cost of marginal investment in A/R $2, 574 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Changing credit standards u u u u 10. 23 The value of $2, 574 is a cost because it represents the maximum amount that could have been earned on the $17, 159 had it been placed in the best equal-risk investment alternative available at the firm’s required return on investment of 15%. Cost of marginal bad debts The cost of marginal bad debts is the difference between the level of bad debts before and after the relaxation of credit standards: Cost of marginal bad debts: Under proposed plan: 0. 02 × $10 × 63, 000 units = 12, 600 Under present plan: 0. 01 × $10 × 60, 000 units = 6, 000 Cost of marginal bad debts $6, 600 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
Changing credit standards u u 10. 24 Bad debts costs are calculated by using the sale price per unit ($10) to identify not just the true loss of variable (or out -of-pocket) cost ($6) that results when a customer fails to pay its account, but also the profit contribution per unit—in this case, $4 ($10 sales prices – $6 variable cost)—that is included in the ‘additional profit contribution from sales’. Thus, the resulting cost of marginal bad debts is $6, 600. To decide whether the firm should relax its credit standards, the additional profit contribution from sales must be compared with the sum of the cost of the marginal investment in accounts receivable and the cost of marginal bad debts. If the additional profit contribution is greater than marginal costs, credit standards should be relaxed.

Credit Terms Cash Discount Period – The period of time during which a cash discount can be taken for early payment. For example, “ 2/10” allows a cash discount in the first 10 days from the invoice date. Cash Discount – A percent (%) reduction in sales or purchase price allowed for early payment of invoices. For example, “ 2/10” allows the customer to take a 2% cash discount during the cash discount period. 10. 27 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Credit Terms u u 10. 28 The terms of sale for customers who have been extended credit by the firm. E. g. ‘net 30’ means the customer has 30 days from the beginning of the credit period to pay the full invoice amount. Some firms offer cash discounts as percentage discounts from the purchase price for full payment without a specified time. E. g. ‘ 2/10 net 30’ means the customer can take a 2% discount from the amount payable if payment is made within the first 10 days of the credit period, or pay the full amount of the amount payable within 30 days of the beginning of the credit period.

Credit Terms 10. 29 u Any discounts for early payment should only be offered after a cost benefit analysis. u Are reflective of the type of business the firm operates. E. g. seasonal, perishable goods etc u Should be reflective of industry standards at a firm level, but reflective of customer riskiness at an individual customer level.

Credit Terms u u 10. 30 Li Hong Company has an average collection period of 40 days (turnover = 365/40 = 9. 1). The firm’s credit terms are net 30, so this period is divided into 32 days until the customers place their payments in the mail (not everyone pays within 30 days) and 8 days to receive, process and collect payments once they are mailed. Li Hong is considering changing its credit terms from net 30 to 2/10 net 30. This change is expected to reduce the amount of time until the payments are placed in the mail, resulting in an average collection period of 25 days (turnover = 365/25 = 14. 6). As shown in the EOQ example (slide 74), Li Hong has a raw material with current annual usage of 1, 100 units. Each finished product produced requires one unit of this raw material at a variable cost of $1, 500 per unit, incurs another $800 of variable cost in the production process and sells for $3, 000 on terms of net 30. Li Hong estimates that 80% of its customers will take the 2% discount and that offering the discount will increase sales of the finished product by 50 units (from 1, 100 to 1, 150 units) per year but will not alter its bad-debt percentage. Li Hong’s opportunity cost of funds invested in accounts receivable is 14%. Should Li Hong offer the proposed cash discount?

Example of Introducing a Cash Discount A competing firm of Basket Wonders is considering changing the credit period from “net 60” (which has resulted in 6 A/R “Turns” per year) to “ 2/10, net 60. ” 10. 32 • Current annual credit sales of $5 million are expected to be maintained. • The firm expects 30% of its credit customers (in dollar volume) to take the cash discount and thus increase A/R “Turns” to 8. • (30% x 10 days + 70% x 60 days = 3 + 42 days = 45 days • 360 days per year / 45 days = 8 turns per year Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
Example of Introducing a Cash Discount • The before-tax opportunity cost for each dollar of funds “tied-up” in additional receivables is 20%. Ignoring any additional bad-debt losses that may arise, should the competing firm introduce a cash discount? 10. 33 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Example of Using the Cash Discount Pre-tax cost of the cash discount 0. 02 x 0. 3 x $5, 000 = $30, 000. Pre-tax opp. savings on reduction in A/R (20% opp. cost) x $208, 333 = $41, 667. Yes! Savings > Costs The benefits derived from released accounts receivable exceed the costs of providing the discount to the firm’s customers. 10. 35 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Example of the Economic Order Quantity Basket Wonders is attempting to determine the economic order quantity for fabric used in the production of baskets. • • • 10, 000 yards of fabric were used at a constant rate last period. Each order represents an ordering cost of $200. Carrying costs are $1 per yard over the 100 -day planning period. What is the economic order quantity? 10. 62 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
Economic Order Quantity We will solve for the economic order quantity given that ordering costs are $200 per order, total usage over the period was 10, 000 units, and carrying costs are $1 per yard (unit). Q* = 2 ($200 ) (10, 000) ( $1 Q* = 2, 000 Units 10. 63 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.

When to Order? Issues to consider: Lead Time – The length of time between the placement of an order for an inventory item and when the item is received in inventory. Order Point – The quantity to which inventory must fall in order to signal that an order must be placed to replenish an item. Order Point (OP) OP = Lead time X Daily usage 10. 65 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
Example of When to Order Julie Miller of Basket Wonders has determined that it takes only 2 days to receive the order of fabric after the placement of the order. When should Julie order more fabric? Lead time Daily usage Order Point 10. 66 = 2 days = 10, 000 yards / 100 days = 100 yards per day = 2 days x 100 yards per day = 200 yards Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Safety Stock – Inventory stock held in reserve as a cushion against uncertain demand (or usage) and replenishment lead time. Our previous example assumed certain demand lead time. When demand and/or lead time are uncertain, then the order point is: Order Point = (Avg. lead time x Avg. daily usage) + Safety stock 10. 68 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

How Much Safety Stock? What is the proper amount of safety stock? Depends on the: • Amount of uncertainty in inventory demand • Amount of uncertainty in the lead time • Cost of running out of inventory • Cost of carrying inventory 10. 71 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

Just-in-Time u An inventory management system used to minimise inventory investment by having materials inputs arrive at exactly the time they are needed for production. u Carries little or no safety stocks. u Relies on exceptional coordination between firm, suppliers and logistics. u Runs the risk of stalling production if inventory fails to arrive when planned for. 10. 72 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

EOQ and JIT example u u u 10. 74 Li Hong Company has an A group inventory item that is vital to the production process. This item costs $1, 500, and Li Hong uses 1, 100 units of the item per year. Li Hong wants to determine its optimal order strategy for the item. To calculate the EOQ, we need the following inputs: Order cost per order = $150 Carrying cost per unit per year = $200 Substituting into EOQ Equation, we get EOQ =√(2 × 1, 100 × $150)/200 ≈ 41 units Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
EOQ and JIT example u The reorder point depends on the number of days Li Hong operates per year. Assuming that he operates 250 days per year and uses 1, 100 units of this item, its daily usage is 4. 4 units (1, 100 250). u If its lead time is two days and Li Hong wants to maintain a safety stock of four units, the reorder point for this item is 12. 8 units ((2 × 4. 4) + 4). However, orders are made only in whole units, so the order is placed when the inventory falls to 13 units. 10. 75 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.

EOQ and JIT example u u u u 10. 76 Now assume the same information as before, but assume that the marginal cost of placing an order is (1) $11 or (2) $2. 1 Order cost of $11 EOQ = √(2 × 1, 100 × $11)/200 = √ 121 = 11 units 2 Order cost of $2 EOQ = √(2 × 1, 100 × $2)/200 = √ 22 = 5 units Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009. Created by Gregory Kuhlemeyer.
EOQ and JIT example As the order cost falls, the EOQ model now tells Li Hong to order fewer units per order, more often. u Applying a marginal order cost, the EOQ model moves towards a JIT system, where inventory arrives when it is needed, with an order cost based on the cost of a phone call to the supplier or a predetermined delivery schedule. u A pure JIT system assumes that suppliers will deliver on time, every time. Without such assurances, pure JIT systems can cause headaches for manufacturers u 10. 77 Van Horne and Wachowicz, Fundamentals of Financial Management, 13 th edition. © Pearson Education Limited 2009.
