Working capital management approaches

What does working capital management aim for?

The primary goal is to maximize firm value while keeping ready access to the cash needed for day-to-day operations and for obligations to creditors. In practice that often means shortening the cash conversion cycle, estimating the liquidity the business needs, and minimizing any excess so that the cash can go to higher-return projects or back to shareholders.

How low a company can go depends on its business model. A manufacturer with a long production process may need to hold inventory for weeks or months. A retailer with many stores and sales on credit needs more inventory and receivables than a software business that is paid up front and holds no stock.

Which current assets are permanent and which are variable?

Companies estimate their needs by first finding the right level of working capital in relation to revenue, then forecasting it from the revenue forecast. They separate two kinds of need.

Current assetsinventory, receivables, staffing and cash

• Permanent current assets Memorize base level, steady all year
  • Base inventory and receivables always needed
  • Matched with long-term funding long-term debt and equity
• Variable current assets Memorize seasonal peak or growth phase
  • Extra inventory and labor needed only at times
  • Matched with short-term funding borrow as needed

Permanent current assets are the base levels of inventory, receivables and staffing needed all year, and they stay fairly constant. Variable current assets are the extra inventory and labor needed in a seasonal peak or a growth phase.

Managers weigh costs against benefits. More inventory protects against a supplier failure or unexpected demand but raises the risk that stock becomes obsolete. Easier customer credit may lift sales but brings higher billing costs and more late payments.

What are the three approaches?

Companies choose two things: how large the current-asset position is compared with sales, and how it is funded. The three approaches line up from the highest cost (more current assets, funded long term) to the lowest (fewer assets, funded short term) for a given level of sales.

Working capital approachfrom highest cost and safest to lowest cost and riskiest

• Conservative Memorize safest, costliest
  • High current assets vs sales Memorize cash, receivables, inventory
  • Mostly long-term funding Memorize long-term debt and equity
  • Who: early-growth, high-margin or expecting flat or rising rates
• Moderate (matched) Memorize balance
  • Moderate current assets vs sales Memorize in between
  • Permanent long term, variable short term Memorize match funding
  • Who: firms that forecast base needs well less sure about peaks
• Aggressive Memorize cheapest, riskiest
  • Low current assets vs sales Memorize lean on cash and stock
  • Heavy short-term funding Memorize even for permanent needs
  • Who: low-margin, precise forecasters or expecting stable or falling rates

	Conservative	Moderate (matched)	Aggressive
Current assets vs sales	high	moderate	low
Funding	mostly long-term debt and equity	permanent needs long term, variable needs short term	heavy short-term borrowing, even for some permanent needs
Pros	no rollover risk, known costs, flexibility in market stress	balance of cost and safety, diversified funding, flexibility for seasonal needs	lowest financing cost, borrow only as needed, fewer restrictions, can refinance if rates fall
Cons	higher cost (long-term rates, equity), cannot borrow only as needed, more restrictions, longer lead time	short-term access may tighten when needed, uncertain short-term cost	rollover and bankruptcy risk in market disruptions, volatile interest cost, may need to lean on costly trade credit
Who uses it	early-growth firms, high-margin firms, those expecting flat or rising rates	firms that forecast base needs well, with less certainty about peaks	low-margin firms, precise forecasters, those expecting stable or falling rates

What is rollover risk?

Rollover risk is the risk that short-term debt cannot be refinanced when it falls due, or only on bad terms, which can push a company into default. The aggressive approach carries the most of it, because short-term debt supports even permanent needs and the debt must be renewed again and again. In a market disruption, such as the 2008–2009 financial crisis, firms that relied on short-term funding were hit hard.

What is match funding?

Match funding pairs the life of the funding with the life of the need. Permanent current assets stay on the balance sheet all year, so they are funded long term. Variable current assets exist only for a season, so they are funded with short-term borrowing that is repaid when the season ends. This is the moderate approach, which is why it is also called the matched approach.

Why would a company pick each approach?

Conservative. Early-growth firms with limited access to short-term debt tend to choose it. So do firms that want little need to reach for capital in market stress, expect flat or rising rates, prefer cash-flow stability to rollover risk, or are established high-margin companies that can pass the higher financing costs on to customers.

Aggressive. Low-margin firms may use it to gain a cost advantage over competitors. Others choose it because they can forecast sales and cash needs very accurately, expect stable or falling rates, plan to shorten their cash conversion cycle, or can quickly sell inventory and collect receivables.

Moderate. Firms choose it when they can forecast base current asset needs accurately but variable needs less well, and want lower financing costs than the conservative approach with lower refinancing risk and more flexibility than the aggressive one. Because permanent needs are funded long term, changes to working capital can be made gradually.

How does the sales strategy interact?

A sales push and the working capital plan cannot be set separately. If a firm wins sales by letting customers pay later, or by selling to customers it would once have turned away, receivables climb and more of them run late. Both have to be financed. The change pays only if the extra profit beats the added cost of chasing, billing and funding those receivables. Stretching the discount window (say from 10 to 15 days) works the same way: customers who take the discount still pay later, so receivables rise.

Exam tip More sales on credit means more receivables, which means more financing. Always follow the extra sales through to the extra funding.

Go deeper Why financial crises hit short-term funders hardest

A firm that funds long-lived needs with short-term paper has to refinance them over and over. When credit markets seize up, as they did in 2008–2009 and briefly in early 2020, lenders refuse to roll the paper over, and the firm must sell assets, raise equity at a poor price or default. Suppliers and banks also tighten terms and credit lines at the same time, so the shock hits both the funding and the trade credit a firm relies on. Long-term funding protects the firm because little or none of its debt falls due during the stress.

Go deeper Spacing debt maturities and matching them to receipts

Even firms that borrow short term can reduce risk with planning. Forecasting cash over a cash conversion cycle and beyond shows when money is needed. Matching the due dates of debt to expected cash receipts means the payment is covered by money that arrives first. Spreading maturities over time avoids having all the debt due on one date, so a single bad refinancing window cannot sink the firm.
