How do changes in working capital affect a company's cash flow?

The impact of working capital changes are reflected in a firm’s cash flow statement. Specifically, the operating cash flow (OCF) section of the cash flow statement details changes in its shorter-term working capital needs. A positive working capital figure (current assets are greater than current liabilities) means a cash inflow for the period measured. In contrast, a negative working capital position means the firm has spent more cash out than it brought in managing its working capital, or commitments, within a year. Analyzing changes in working capital can be important for any business, but is especially important for firms with seasonal or erratic cash flow needs.
