Working Capital Management
- What is the meaning of the terms working capital management , gross working capital , and net working capital****?
Working capital management involves determining the firm’s policy for managing its working capital, i.e., the firm’s current assets and current liabilities. It involves managing the firm’s cash, marketable securities, receivables, inventories, accounts payable, and other short-term payables. Gross working capital refers to the firm’s current assets used in operations, including such items as cash, marketable securities, accounts receivable, and inventory. Net working capital refers to a firm’s current assets minus its current liabilities.
- What is the tradeoff between profitability and liquidity and profitability and risk in working capital management?
Since current assets typically earn a lower return than long-term fixed assets, an overly strong liquidity position could lower firm profitability. An effective working capital policy carefully balances the need to have sufficient liquidity with the need to earn an attractive return on invested capital. Firms may adopt more aggressive working capital management policies that have less of a drag on firm profitability, but at higher levels of risk.
- What are the similarities and differences among the maturity-matching, conservative, and aggressive approaches for managing working capital?
The nature of many businesses may cause seasonal variations in a firm’s current assets. Working capital management approaches differ in terms of how the firm finances these seasonal variations in current assets. Three common ways of dealing with such seasonal variations are the maturity-matching, conservative, and aggressive approaches.
- Under the maturity-matching approach , the firm finances long-term assets (fixed assets and all permanent current assets) with long-term sources of funds (long-term debt and equity). By matching its seasonal variations in current assets with current

liabilities of the same maturity, the firm essentially hedges against changes in short- term interest rates.
- Under the conservative approach , the firm finances long-term assets, all permanent current assets, and some temporary current assets with long-term sources of funds. This approach relies more heavily on long-term financing than do the other approaches.
- Under the aggressive approach , the firm finances all temporary current assets and some of its permanent current assets with short-term sources of financing. This approach relies more heavily on short-term financing than do the other approaches.
2. How would an increase in short-term interest rates affect a firm under the conservative, maturity-matching, and aggressive approaches to managing working capital?
- Under the conservative approach , the firm uses more long-term financing and less short-term financing to finance current assets and is therefore less vulnerable to increases in short-term rates than under the other approaches. If short-term interest rates rise, the firm has fewer short-term sources that it will need to refinance at the higher rates.
- Under the maturity-matching approach , the firm has essentially hedged against unexpected changes in short-term interest rates. If short-term interest rates increase, the increases in the return earned on an equal amount of short-term current assets should offset the increased cost of short-term funds.
- Under the aggressive approach , increases in short-term interest rates will require the firm to refinance more current assets at the new higher rates. The firm could be in jeopardy of being shutoff by suppliers.
- What is a firm’s operating cycle? How is it calculated?
The operating cycle is the period between the acquisition of inventory and the collection of cash from accounts receivable that arises from the credit sale of the finished goods produced from that inventory. Calculating the operating cycle involves adding a firm’s average receivable collection period and its average inventory-processing period.
- What is a firm’s cash conversion cycle? How is it calculated?
The cash conversion cycle is the number of days between receiving the payment of accounts receivable and receiving cash from accounts payable. By adjusting the operating cycle to account for the financing a firm receives by paying its suppliers on credit, the cash conversion cycle represents the length of time that a firm has cash tied up in the business. Computing a firm’s cash conversion cycle involves summing the average receivable collection period and the average inventory processing period, and then subtracting the accounts payable payment period.

daily cash flows fluctuate randomly from day to day. Thus, the Miller-Orr model incorporates the uncertainty of future cash flows.
- What are compensating balances and how do they affect a firm’s cash balances?
A compensating balance is the demand deposit balance maintained by a corporate borrow to compensate for bank expenses in servicing a loan or line of credit. Thus, a compensating balance increases a firm’s cash balances in the form of demand deposits.
- What are five different types of marketable securities?
Marketable securities are securities that are easily sold. On a firm’s balance sheet, marketable securities are assets that the firm can readily convert into case. Marketable securities include government securities such as US Treasury bills, short-term tax- exempt instruments, commercial paper, negotiable certificates of deposit, and repurchase agreements. Bankers’ acceptances are another type of marketable security.
- What is the meaning of the terms disbursement float , collection float , and net float****? Does a firm benefit from an increase or decrease in its net float?
Disbursement float is the lapse in time between when a firm deducts a payment from its checking account and when funds are actually withdrawn from its account. Collection float is the delay in time between when a payer deducts a payment from its checking account and when the payee actually receives the funds in a spendable form. Net float is the difference between the disbursement float and the collection float. A firm benefits by reducing its net float. For example, suppose a firm could reduce its net float by $ million and the firm can earn a rate of 6 percent per year on short-term funds. The firm can earn (or save) $25 million (0.06) (1/365) = $4,110 per day.
- How does a lockbock system speed up a firm’s collections?
Under a lockbox system, customers send incoming checks to a special post office box maintained by a local bank. The lockbox collection system eliminates processing float and reduces the firm’s internal processing costs because the bank handles the clerical work for a fee. The local bank typically provides a daily record of the receipts electronically in a format that easily facilitates updating the firm’s accounts receivable records.
- What are three advantages of using electronic funds transfers?
Electronic funds transfer (EFS) refers to the transfer of funds between accounts by electronic means rather than conventional paper-based payment methods such as check writing. EFTs can save time for a firm, lower its personnel and material costs, and reduce errors by eliminating paper documents and mail delivery.
- How can a firm use payable through drafts and zero balance accounts to control disbursements?
Payables through draft (PTF) refers to a draft payable through a designated bank, drawing funds from the issuer’s own account. PTDs are not payable on demand. To receive payment, the bank must present the PTD to the issuing firm. This process allows
the firm to delay depositing the necessary funds to cover payment and the firm can keep smaller cash balances. Corporations often use PDFs to pay freight bills.
A zero balance account (ZBA) is a checking account that corporations use to accelerate collections of funds from subsidiaries or to control funds disbursed to pay trade creditors. Thus, a firm can establish a zero-balance collection account or a zero-balance disbursing account. For example, under a zero balance disbursing account, a firm creates one master disbursement account to service multiple subsidiary accounts at the bank. These subsidiary accounts are separate accounts that are set up for payroll, payables, and other purposes. The bank automatically transfers enough funds from the master disbursement account to the subsidiary accounts each day to cover all checks that holders presented to that bank on that day. Only the master account maintains a cash balance; each subsidiary account carries a zero balance each day by eliminating idle cash.
- What is electronic data interchange (EDI)? How does EDI affect the way in which firms manage their working capital?
EDI is the exchange of information electronically by computers. EDI can lower a firm’s personnel costs, material costs, and costs due to errors by eliminating paper documents and mail delivery. EDI savings are so substantial that some firms now charge fees for using paper documents. EDI has dramatically changed the way many firms conduct business and will continue to affect how firms manage their working capital.
- How can managers and analysts use a credit scoring model to assess a customer’s credit?
A credit scoring model is a statistical model used to predict the creditworthiness of credit applicants. When a firm uses credit scoring, it assigns a numerical rating to a customer based on certain company-specific information. The firm bases its decision to grant or refuse credit on the numerical credit score.
- List and discuss the five Cs of credit. Which Cs would be more important for commercial customers? Consumers? Why?
Credit analysts generally take into consideration at least five factors when determining whether to grant credit including character, capacity, capital, collateral, and conditions. Capacity, conditions, and collateral would be more important for commercial customers. Character and capital would be more important for consumers. An applicant’s prior payment history is generally the best indicator of character. Credit granting firms often consider the customer’s debt-to-equity ratio and interest coverage ratio.
- Explain two ways a firm can monitor its accounts receivable.
Common methods used to monitor accounts receivable include developing an aging schedule and determining the average age of receivables. An aging schedule classifies

- How do safety stock levels and reorder points to allow time for delivery affect the basic EOQ model?
Firms typically establish a minimum level of inventory, known as a safety stock , to prevent losing sales due to stockouts. If suppliers immediately delivered inventory when a firm placed an order, the firm would reorder inventory whenever the inventory level fell to the safety stock level. To allow for delivery time, a firm needs to reorder inventory before the inventory level reaches the critical safety stock level. The reorder points represent the times when the firm actually places its inventory order. The pace of inventory depletion and the length of time for inventory delivery after placing order affect reorder points.
- What is a just-in-time (JIT) inventory system? What type of relationship and level of cooperation must exist between manufacturers and suppliers for a JIT system to work effectively?
In a just-in-time (JIT) system, materials arrive in the production process exactly when needed. JIT inventory systems became popular and necessary in some production processes in the 1980s when high interest rates increased the opportunity costs of carrying high levels of inventory.
JIT systems require care in the planning and scheduling of inventory by managers. The success of a JIT system depends heavily on extensive cooperation with the firm’s suppliers. Because of the extensive planning involved, JIT systems often rely on relatively few suppliers, and they usually require frequent deliveries from these suppliers of the exact amounts needed and in a specific order. Delivery schedules, quantities, quality, and instantaneous communication with suppliers are essential factors in a successful JIT system.
- What is a materials requirement planning (MRP) system? What types of products are most suited for an MRP system?
In a materials requirement planning (MRP) system , managers order and schedule production of inventories essentially backwards through the production process. Managers first determine the desired finished goods inventory level. From this, they determine the appropriate levels of work-in-progress inventories that the firm needs to produce the finished goods. Next, they determine the quantity of raw materials needed to have on hand. These computer-based MRP systems are most effective for the production of complicated goods that require numerous inventory components.
