Understand working capital

Here is the distinction that matters most, and the one worth reading twice: changes in receivables, inventory, and payables move cash but do not move working capital. Working capital moves when a noncurrent asset, a noncurrent liability, or equity changes.

The reason is arithmetic, not opinion. Working capital is the whole current section netted against itself, so anything that happens strictly inside that section cancels out. Let a customer stretch from 45 days to 60: receivables rise, and whatever funded that stretch — the cash balance falling, the line of credit rising, payables rising — is also a current account. One current account goes up, another current account moves to match, and the difference between total current assets and total current liabilities is unchanged. The company is meaningfully worse off in cash terms, and its working capital did not move a dollar.

Flip it around and the rule reads as a definition: working capital changes when cash moves for a reason that lives outside the current section. Buy a truck and cash leaves for a fixed asset — working capital falls. Draw a five-year term loan and cash arrives from a long-term liability — working capital rises. Pay a distribution and cash leaves for equity — working capital falls. Earn a profit, and the earnings land in the current section without a matching current obligation — working capital rises. That last one is why net income is a source and why a loss is a use.

So: an operating-cycle problem is a cash problem. Slow collections, a bloated inventory position, suppliers tightening terms — those are real, they belong in the analysis, and they are diagnosed on CCA and in the operating-cycle section of Funds Flow. They are not working-capital problems, and describing them that way hides which lever actually fixes them.

Because working capital only moves when something structural moves, it reads as a measure of long-term sustainability rather than of this month's liquidity. It accumulates. Years of retained earnings, capital the owners put in, and long-term debt raised and held build it up; distributions, capital spending, and principal amortization draw it down. What you are looking at is the residue of every structural decision the company has made.

That is exactly what makes it lendable. Consider a borrower who has a bad year and posts a loss. If the company carries substantial working capital, a bank can usually still lend: the cushion says this is a financially strong company having a tough year, with the capacity to absorb the setback and keep operating while it recovers. The same loss at a company with thin or negative working capital is a different conversation entirely — there is nothing underneath to absorb it. One year of results is an event; the working-capital position is the balance-sheet record of whether the company can survive events.

This is also why minimum working capital appears so often as a loan covenant, usually alongside a coverage test. Coverage asks whether this year's cash flow services this year's debt. Minimum working capital asks whether the balance sheet still has a cushion at all. A borrower can pass one and fail the other, and the pair is more informative than either alone.

To see what moved working capital and why, open Sources & Uses. The statement is built on a working-capital basis: it opens at Beginning Working Capital, lists every source, lists every use, and lands on Ending Working Capital, with a Check Figure that ties the arithmetic. Nothing on it can be typed over — every line is derived from the active Case.

The most common sources are net income, depreciation, new long-term debt, and capital paid in by the owners. Depreciation appears as a source for a specific reason worth understanding rather than memorizing: it was subtracted in arriving at net income but consumed no current asset when it was charged, so adding it back restores the working capital that net income alone understates. The cash for that asset left in an earlier year, when it was purchased. Amortization sits there for the same reason, and so do asset sales, decreases in other noncurrent assets, and increases in other noncurrent liabilities.

The most common uses are distributions or dividends to owners, principal payments on long-term debt, and purchases of fixed assets. Each one is cash leaving the current section for something outside it. Note that principal payments show up here while interest does not — interest is an expense already inside net income, but principal repayment retires a long-term liability, and that is a use of working capital.

Read the pattern across years rather than any single column. A company whose distributions and capital spending consistently exceed net income plus depreciation is consuming its cushion, however comfortable one good year looks in isolation. A company building working capital year after year is accumulating exactly the staying power a lender is underwriting.

Watch, too, for a use that involves no cash at all. Netcase computes working capital from the full current subtotals, so the current portion of long-term debt sits in current liabilities. Every year, part of a term loan's balance rolls from long-term into CPLTD, and that reclassification alone reduces working capital before a single payment is made — it appears on the statement as a decrease in long-term debt. This is not a quirk to work around. It is the measure behaving correctly: obligations moving into the twelve-month window genuinely shrink the cushion.

The current ratio divides current assets by current liabilities; working capital subtracts one from the other. Same two inputs, and the subtraction is the more useful of the two operations, because dividing throws away the one thing you most need to know: how big this company is.

Take a company with $2,000,000 of current assets and $1,000,000 of current liabilities. Its current ratio is 2.0, and its working capital is $1,000,000. Now take a company with $2.00 of current assets and $1.00 of current liabilities. Its current ratio is also 2.0. Its working capital is one dollar. Read only the ratio and the two are indistinguishable — identical liquidity, identical health. Read the dollars and nobody hesitates: the first company has a million-dollar cushion and the second has a dollar. Scale is not a detail. It is most of the answer.

Use the ratio for what it is good at — comparing a company against its own history, or against peers of a similar size, where the scale is already controlled for. But the dollar figure is what tells you whether a company can absorb a bad year, and it is the figure a covenant is written against, because a lender needs to know the size of the cushion and not just its shape. Netcase reports both on the Ratios page, and both in the Cash & Working Capital metric group.

One honest caveat in the other direction, so the point holds up when someone pushes back: dollars alone are scale-blind too. A $1,000,000 cushion is substantial for a company doing $5,000,000 of revenue and thin for one doing $500,000,000. Read the dollars first, then size them against the business — Netcase's Working Capital / Assets and Working Capital Turnover metrics are there for exactly that. What you should not do is read the ratio alone and believe you have seen the cushion.

The pages divide along this line already, so let the question pick the page. When the question is "can this company withstand a setback, and can we lend into it" — the working-capital question — go to Sources & Uses, and to the working-capital section at the top of Funds Flow. When the question is "why is cash down when profit is up" — the operating-cycle question — go to Cash Cycle Analysis and to the operating-cycle section of Funds Flow, where receivables, inventory, and payables each get their own line.

Funds Flow is worth knowing well because it makes the whole relationship visible in one place. Its first numbered section resolves to Net Change in Working Capital, built from exactly the noncurrent and equity movements described above. Its second section, Operating Cycle Cash Impact, then opens up what receivables, inventory, and payables did — and that section reconciles to cash, not to working capital. Two sections, two measures, one page, and the sequence itself teaches the distinction.

Both measures respond to your forecast assumptions, but not to the same ones. Turn days move projected cash and the line of credit; they leave projected working capital essentially where it was. Distributions, capital spending, debt amortization, new borrowing, and profitability are what move projected working capital — and therefore what determines whether a minimum working capital covenant passes in year three. If a covenant is failing, negotiating with the turn days will not fix it. Look at the sources and uses instead.

Reading the concept changes nothing. In a Case, projected working capital moves when you change profitability, distributions, capital spending, or long-term debt — the noncurrent and equity drivers. Changing turn days moves projected cash and the LOC while leaving working capital roughly unchanged. Historical working capital moves only by correcting actuals in Caseload, including the current versus long-term classification the measure depends on.
