Working Capital Management
Decisions relating to working capital and short term financing are referred to as working capital management. These involve managing the relationship between a firm’s short-term assets and its short-term liabilities.
As above, the goal of Corporate Finance is the maximization of firm value. In the context of long term, capital investment decisions, firm value is enhanced through appropriately selecting and funding NPV positive investments. These investments, in turn, have implications in terms of cash flow and cost of capital.
The goal of Working capital management is therefore to ensure that the firm is able to operate, and that it has sufficient cash flow to service long term debt, and to satisfy both maturing short-term debt and upcoming operational expenses. In so doing, firm value is enhanced when, and if, the return on capital exceeds the cost of capital; See Economic value added (EVA).
Working capital is the amount of capital which is readily available to an organization. That is, working capital is the difference between resources in cash or readily convertible into cash (Current Assets), and cash requirements (Current Liabilities). As a result, the decisions relating to working capital are always current, i.e. short term, decisions.
In addition to time horizon, working capital decisions differ from capital investment decisions in terms of discounting and profitability considerations; they are also “reversible” to some extent. (Considerations as to Risk appetite and return targets remain identical, although some constraints – such as those imposed by loan covenants – may be more relevant here).
Working capital management decisions are therefore not taken on the same basis as long term decisions, and working capital management applies different criteria in decision making: the main considerations are (1) cash flow / liquidity and (2) profitability / return on capital (of which cash flow is probably the more important).
* The most widely used measure of cash flow is the net operating cycle, or cash conversion cycle. This represents the time difference between cash payment for raw materials and cash collection for sales. The cash conversion cycle indicates the firm’s ability to convert its resources into cash. Because this number effectively corresponds to the time that the firm’s cash is tied up in operations and unavailable for other activities, management generally aims at a low net count. (Another measure is gross operating cycle which is the same as net operating cycle except that it does not take into account the creditors deferral period.)
* In this context, the most useful measure of profitability is Return on capital (ROC). The result is shown as a percentage, determined by dividing relevant income for the 12 months by capital employed; Return on equity (ROE) shows this result for the firm’s shareholders. As above, firm value is enhanced when, and if, the return on capital, exceeds the cost of capital. ROC measures are therefore useful as a management tool, in that they link short-term policy with long-term decision making.
Management of working capital
Guided by the above criteria, management will use a combination of policies and techniques for the management of working capital. These policies aim at managing the current assets (generally cash and cash equivalents, inventories and debtors) and the short term financing, such that cash flows and returns are acceptable.
* Cash management. Identify the cash balance which allows for the business to meet day to day expenses, but reduces cash holding costs.
* Inventory management. Identify the level of inventory which allows for uninterrupted production but reduces the investment in raw materials – and minimizes reordering costs – and hence increases cash flow; see Supply chain management; Just In Time (JIT); Economic order quantity (EOQ); Economic production quantity (EPQ).
* Debtors management. Identify the appropriate credit policy, i.e. credit terms which will attract customers, such that any impact on cash flows and the cash conversion cycle will be offset by increased revenue and hence Return on Capital (or vice versa); see Discounts and allowances.
* Short term financing. Identify the appropriate source of financing, given the cash conversion cycle: the inventory is ideally financed by credit granted by the supplier; however, it may be necessary to utilize a bank loan (or overdraft), or to “convert debtors to cash” through “factoring”.
