Working Capital
Working capital is measured as the difference among organization present assets and its current liabilities. Therefore, it is interpreted by some as a measure of a firm's liquidity or its ability to pay its bills on a short-term basis. However, excess investment in working capital can be costly for a firm as the rate of return on an organization working capital is likely to be lower than alternative long-term investment project returns. Therefore, the maintenance of excessively high working capital builds too much liquidity and hence lowers overall returns.
