Cash management is concerned with selecting the optimal combination of current assets —cash, marketable securities, accounts receivable and inventory — and current liabilities, or short-term funds to finance those current assets. For companies with international operations, cash management must take into account the impact of currency fluctuations. Cash management can be organised on a decentralise basis with autonomous operating units, or by means of a fully centralised cash management program. Decentralising allows the corporation to operate with a smaller amount of cash and allows it to reduce FX transaction costs by increasing the volume of FX transactions. It can also lead to cost-saving in terms of payments netting.
