Other working capital

Other working capital, as it appears on the cash flow statement, captures the aggregate cash effect of changes in the operating assets and liabilities of the business during the period. It represents the difference between profit recognised on the income statement under accrual accounting and the cash collected and paid in the same period.

It's presented in the operating section of the indirect method cash flow statement as a series of line items adjusting net income from an accrual basis to a cash basis: an increase in accounts receivable is a use of cash because revenue was recognised but not yet collected, a decrease in inventory is a source of cash because goods were sold without being replaced, an increase in accounts payable is a source of cash because costs were incurred but not yet paid, and an increase in deferred revenue is a source of cash because customers paid before the company performed. The net of all these movements is what many cash flow statements compress into a single other working capital line, though better-quality disclosures break each component out separately.

Working capital movements are one of the most important and most overlooked elements of cash flow analysis. They explain why a profitable company can consume cash and why a modestly profitable one can generate it: a fast-growing business that extends credit to customers and builds inventory will typically absorb cash into working capital even as it reports rising net income, while a business with strong supplier terms and prepaying customers can generate cash well in excess of reported earnings.

Sustained working capital outflows relative to net income are a warning sign of either aggressive revenue recognition, deteriorating collections, or a business model that requires more capital to grow than the income statement suggests. Unusually large working capital inflows that flatter operating cash flow in a single period deserve equal scrutiny, since they may reflect one-time timing benefits that will reverse in subsequent periods.

Data sites usually show each movement on its own line, such as change in accounts receivable, change in inventories, change in accounts payable, change in unearned revenues and change in income taxes, with a final line for other net operating assets that collects the smaller remaining items. Each line shows the cash effect: a positive figure added cash, a negative one used it. Data sites may also show their own change in net working capital among the supplemental items, calculated from the balance sheet by their own definition, so it usually won't equal the sum of these lines.
