7.1 Managing current assets and current liabilities

Liquidity, you will recall, is a firm's ability to meet its short-term debts, and cash is the most liquid asset, because it can be spent immediately. Non-cash current assets, mainly receivables and inventory, are less liquid because it may take time to turn them into cash. For example, ratios measuring receivables collection periods and inventory turnover rates, estimate how long it is taking to convert receivables and inventory into cash. In general the more current assets a firm holds the greater its liquidity (measured by the current ratio). If liquidity is, or becomes, very important managers may decide to hold proportionately more cash and/or marketable securities (measured by the quick ratio) than non-cash assets, receivables and inventory.

There is always a trade-off in holding high levels of cash assets because they earn very little return. In general, managers can only reduce the risk of becoming less liquid by reducing the overall return on current assets, and on total assets (the ROA measure).

Note Figure 12.1 The working capital cycle

Another factor affecting net working capital is the firm's use of current versus long-term debt. Again, this poses the risk-return trade-off. All else being constant, the more that managers rely on short-term debt or current liabilities to finance investment in assets the lower will be the firm's liquidity. Think about this!

However, using current liabilities costs less (in interest) than long-term debt and is a flexible means of funding fluctuating needs for assets.

The major disadvantage of short-term debt is that it must be repaid or 'rolled over' more often, and any deterioration in the firm's overall financial condition may be made worse if the firm can't refinance the short-term debt. So liquidity and longer-term solvency are linked.

Another risk is linked to the interest rates. Every time funding arrangements are renewed the interest rates will also be reviewed. Any change in the lender's perception of the firm's riskiness will lead to higher interest being charged. So short-term interest rates are likely to change more often than interest on long-term loans.

Where possible cash should be held in interest bearing accounts and drawn on only when actually needed to pay accounts, otherwise there is an unnecessary opportunity cost in terms of lost interest.

The following reading explains the management function of cash and marketable securities. Note the formula for calculating optimum cash withdrawal amounts. You don't need to learn the formula! Make brief notes of the main points.
