A firm does not usually die from a bad project; it dies from a Tuesday when salaries are due and the bank balance is short. Working capital management is the discipline that prevents that Tuesday — the management of short-term assets and liabilities so that operations never stall for cash while no rupee sits idle earning nothing.

This is the second card of the financial management series. The first card of the series set the full frame — objectives, the three-decision tripod, risk-return, time value — and this card takes up its short-term leg in full: the operating cycle, the financing approaches, cash, receivables, inventory and payables.

What Working Capital Actually Is

Definitions that examiners distinguish between, in the order they are usually confused.

1. Gross working capital. Total current assets — cash, marketable securities, debtors, inventory — the stock of short-term resources on the balance sheet at a moment.
2. Net working capital. Current assets minus current liabilities — the cushion, positive or negative, that tells whether short-term resources cover short-term claims.
3. Permanent vs temporary. The floor of working capital a firm carries even at its quietest (permanent) versus the seasonal spike above it (temporary) — the split that decides how each portion should be financed.
4. The operating view. Working capital is not a balance-sheet number but a circulating fund — cash becoming inventory becoming receivables becoming cash, in a loop that must never stop.
5. The exam trap. Gross and net are different questions — quoting one when the paper asks the other is the most common single-mark loss in this chapter.

Why It Matters: The Two Faces

Too little and too much are both fatal — in different ways and at different speeds.

1. Too little. Liquidity crunch — missed salaries, lost cash discounts, emergency borrowing at punitive rates, and in the limit, insolvency with profitable order books.
2. Too much. Idle funds — cash and inventory earn little or nothing, receivables default risk mounts, and return on investment sags below what the same capital deserved elsewhere.
3. The trade-off named. Liquidity vs profitability: every rupee held in current assets is safe and sterile; every rupee freed is productive and exposed — the manager runs the boundary between them.
4. The speed factor. A fast operating cycle shrinks the working capital need for the same sales — efficiency substitutes for funding, the cheapest source of short-term finance there is.
5. The risk-return frame. Same axis as Part 1 of the series, now at the level of daily operations: more liquidity is less risk and less return, by definition.

The Operating Cycle in Full

The clock that governs everything in this chapter.

1. The loop. Cash → raw materials → work-in-progress → finished goods → debtors → cash — five stations, four waiting periods, one loop.
2. Gross operating cycle. Inventory holding period + receivables (debtor) collection period — days from paying for material to collecting from customers.
3. Net operating cycle. Gross cycle minus payables deferral period — the days the firm itself must finance; the payables period is the suppliers’ money doing the work first.
4. Cash cycle vs cash turnover. The cycle in days versus how many times it completes in a year (365 ÷ net cycle) — turnover frames working capital need as a multiple of daily sales.
5. The calculation rule. Every period is closing balance logic — average inventory divided by daily cost of goods, average debtors divided by daily credit sales — state the formula, then the averages, then the days.
6. The diagnosis use. A lengthening cycle is the earliest visible symptom of slack — inventory piling, collection slowing — visible quarters before the profit and loss statement admits anything.

Estimating the Requirement

Two methods, one conservative and one operational.

1. The percentage-of-sales method. Working capital as a stable ratio of sales — quick, adequate for steady firms, blind to changes in credit terms or cycle speed.
2. The operating cycle method. Estimate every component at its planned level — cash, each inventory stage, debtors, minus creditors — and sum; slower but honest, and the method long-answer marks want.
3. The forecasting balance sheet. Projected current assets minus projected current liabilities — the requirement as a completing figure, tying the estimate into the full financial plan.
4. Seasonality adjustment. Peak-season and off-season estimates computed separately; the financing plan must cover the peak, not the average — averages starve July to feed December.
5. The margin rules. Add a safety cushion for contingencies and exclude intangibles and non-operating current assets from the base — two small disciplines that separate a clean estimate from a naive sum.

Financing Working Capital

Matching, conservative, aggressive — three postures toward the same requirement.

1. The matching approach. Permanent needs financed long, temporary needs financed short — maturities aligned with the lives of the assets they fund.
2. The conservative approach. A share of even temporary needs financed long-term — lower risk, higher cost, and the unglamorous reason most stable firms survive bad quarters.
3. The aggressive approach. A share of even permanent needs financed short-term — cheaper and riskier, rolling over exposure exactly when credit tightens; banks price this posture back into limits.
4. The sources short. Trade credit, cash credit and overdraft, short-term loans, commercial paper, factoring and internal accruals — six names, each one line of cost and flexibility.
5. The bank view. Lenders sanction working capital against the operating cycle and margins — a drawing-power calculation, not a favour; the firm that understands this negotiates limits it can actually use.

Cash Management

The one component that earns nothing — manage it with models, not mood.

1. Motives for holding cash. Transactions, precaution, speculation — Keynes’s trio, one sentence each; asked as a two-mark short note more often than any other item in this chapter.
2. The objectives. Meet obligations on time while holding the minimum idle balance — solvency without sterility.
3. The Baumol model. Cash replenished in fixed lots against known usage — the inventory model applied to cash; know the square-root trade-off between conversion cost and holding cost.
4. The Miller-Orr model. Cash wanders between a lower limit, a return point and an upper limit — control limits for fluctuating flows; the two models earn one comparison sentence each in any long answer.
5. The management tools. Cash budgeting for foresight, synchronisation of inflows and outflows, float management (speed collections, slow disbursements ethically), and short-term parking of surpluses.

Receivables Management

Credit policy is a loan business inside the operating business — run it like one.

1. The trade-off. Liberal credit lifts sales and ties up funds and invites default; tight credit does the reverse — the policy sits where marginal profit from extra sales equals marginal cost of the investment and bad debts.
2. Policy variables. Credit period, cash discount and its period, credit standards, collection policy — four dials, and every question about receivables turns one of them.
3. The credit evaluation step. Character, capacity, capital, conditions — the analyst’s checklist before the dials are set for any customer.
4. Collection policy ladder. Reminder letters → follow-ups → personal visits → agency or legal action — firmness escalating with age of debt; the ageing schedule is the instrument panel for the whole ladder.
5. Factoring and forfeiting. Selling receivables for liquidity (factoring, with or without recourse) versus forfeiting medium-term export receivables — two end-of-chapter names that appear as short notes.

Inventory Management

The largest current asset for most firms — and the most hostage-prone.

1. The costs named. Ordering costs vs carrying costs — the tension every inventory model arbitrates.
2. The EOQ square root. The order size that minimises total inventory cost — learn the formula, the assumption set (known demand, constant costs, instant delivery), and the meaning of each term in the radical.
3. ABC analysis. The vital few — the small share of items carrying most value get tight control, the trivial many get simple rules — classification as management attention allocation.
4. Reorder point and safety stock. Lead-time demand plus a buffer for variability — the two numbers that decide stockouts versus overstocking at the moment of reordering.
5. Just-in-time. Order so arrival matches use — carrying cost near zero, exposure near total; one line on the philosophy, one on its fragility.

Payables Management

The forgotten component — the firm’s own free (or not) source of finance.

1. The deferral window. Supplier credit is an interest-free loan up to the due date — managing payables is deciding how much of that window to use without spending the firm’s reputation.
2. The discount decision. Forgoing a cash discount is borrowing at a steep implicit rate — the 2/10 net 30 arithmetic; computing the annualised cost of skipping the discount is a classic numerical.
3. The stretching decision. Paying beyond terms funds the firm at the cost of supplier goodwill and future credit terms — a liquidity lever that quietly reprices every later purchase.
4. The relationship frame. Suppliers are repeat players — a firm that pays late in tight times is a firm that is served late in tight times; the balance sheet is not the only place the cost appears.
5. The reverse view. The firm is a customer running its own suppliers’ receivables policy — the same four dials read from the other side of the counter.

How Exams Ask This Chapter

The question shapes, with their marking engines.

1. Cycle numericals. Compute inventory days, debtor days, creditor days, then gross and net operating cycle — a guaranteed numerical; the marks are in the averages and the labels.
2. Financing-approach debates. Compare matching, conservative and aggressive — structure with the risk-return axis from Part 1 and one financing example each.
3. Component short notes. Baumol, Miller-Orr, EOQ, ABC, ageing schedule — any name above as a five-mark note: definition, mechanics, one limitation.
4. Policy questions. Advise on credit policy or discount decision — calculated advice, not opinion; show the marginal cost and the marginal gain side by side.
5. Swap-error watch. Gross vs net working capital, cash cycle vs cash turnover, factoring vs forfeiting — the pairs most often swapped under time pressure; label each line of the answer with the term it defines.

8. Receivables. Four policy dials; 5 Cs evaluation; ageing schedule instrument panel.
9. Inventory. EOQ balance of ordering vs carrying costs; ABC for attention; safety stock.
10. Payables. Free credit window; discount arithmetic; reputation cost of stretching.

Conclusion: The Loop That Must Not Stop

Working capital is the operating loop of the firm — cash to inventory to receivables and back — and its management is the craft of keeping that loop fast, fully funded and free of waste. This card walked the loop in order: the definitions, the operating cycle arithmetic, the requirement estimate, the three financing postures, then the four components each in turn. The opening card of the series established the tripod of decisions of which this is the short-term leg; the management of the long-term leg — capital budgeting and capital structure — arrives in the next part of the series. Master the cycle here, and every later technique is arithmetic layered on a loop you already understand.
