3. Using the information from steps 1 and 2, calculate incremental credit costs under the revised credit policy.
4. Ignoring credit costs, calculate incremental profits under the new credit policy.
5. If, and only if, incremental profits exceed incremental credit costs, select the new credit policy.
INVENTORY MANAGEMENT
Inventory in the form of raw materials, work in process, or finished goods is held (i) to facilitate the production process by both ensuring that supplies are at hand when needed and allowing a more even rate of production and (2) to make certain that goods are available for delivery at the time of sale.
Although, conceptually, the inventory management problems faced by multinational firms are not unique, they may be exaggerated in the case of foreign operations. For instance, MNCs typically find it more difficult to control their overseas inventory and realize inventory turnover objectives. There are a variety of reasons: long and variable transit times if ocean transportation is used, lengthy customs proceedings, dock strikes, import controls, higher duties, supply disruption, and anticipated changes in currency values.
Production Location and Inventory Control
Many U.S. companies have eschewed domestic manufacturing for offshore production to take advantage of both low-wage labor and a grab bag of tax holidays, low-interest loans, and other government largess. But a number of firms have found that low manufacturing cost isn't everything. Aside from the strategic advantages associated with U.S. production, such as maintaining close contact with domestic customers, onshore manufacturing allows for a more efficient use of capital. In particular, because of the delays in international shipment of goods and potential supply disruptions, firms producing abroad typically hold larger work-in-process and finished goods inventories. The result is higher inventory-carrying costs.
Advance Inventory Purchases
In many developing countries, forward contracts for foreign currency are limited in availability or are nonexistent. In addition, restrictions often preclude free remittances, making it difficult, if not impossible, to convert excess funds into a hard currency. One means of hedging is to engage in anticipatory purchases of goods, especially imported, items. The trade-off involves owning goods for which local currency prices may be increased, thereby maintaining the dollar value of the asset even if devaluation occurs, versus forgoing the return on local money market investments.
For example, suppose that Volkswagen do Brasil is trying to decide how many months' worth of components to carry in inventory. The present price of a component is DM 100, and this price is rising at the rate of 0.5% monthly. The Deutsche mark holding cost is estimated at 1 % monthly, including insurance, warehousing, and spoilage, but excluding the opportunity cost of funds. Under these circumstances, where holding costs exceed anticipated cost increases by 0.5% monthly, Volkswagen should maintain the minimum parts inventory necessary to achieve its targeted output in Brazil.
Assume now that Volkswagen has excess cruzeiro balances in Brazil on which it is earning a nominal monthly rate of 2%. However, under Brazil's system of mini-devaluation, the cruzeiro is expected to devalue against the Deutsche mark by 3% in each of the next three months, 2% in the fourth month, and 1% thereafter. Since other investment opportunities are limited or nonexistent because of currency and financial market controls, VW's opportunity cost of funds in Deutsche marks (the 2% nominal rate it earns on cruzeiros less the expected devaluation) for the next six months, month by month, equals

Adding this opportunity cost of funds to the previously given monthly holding costs of 1 % yields the total monthly individual and cumulative DM costs of carrying inventory for the next six months:

Based on the cumulative carrying costs and price increases, it is now apparent that the existence of anticipated cruzeiro devaluations, unmatched by correspondingly higher nominal interest rates—that is, the international Fisher effect is not expected to hold—should lead Volkswagen do Brasil to hedge a portion of its cash balances by purchasing four months' worth of inventory at today's prices (and at today's DM : cruzeiro exchange rate). In other words, it will pay Volkswagen to purchase this amount of inventory in advance in order to minimize losses in the real value of its cruzeiro cash balances.
Inventory Stockpiling
Because of long delivery lead times, the often limited availability of transport for economically sized shipments, and currency restrictions, the problem of supply failure is of particular importance for any firm that is dependent on foreign sources These conditions may make the knowledge and execution of an optimal stocking policy, under a threat of a disruption to supply, more critical in the MNC than in the firm that purchases domestically.
The traditional response to such risks has been advance purchases. Holding large amounts of inventory can be quite expensive, though. In fact, the high cost of inventory stockpiling—including financing, insurance, storage, and obsolescence—has led many companies to identify low inventories with effective management. In contrast, production and sales managers typically desire a relatively large inventory, particularly when a cutoff in supply is anticipated.
Some firms do not charge their managers’ interest on the money tied up in inventory. A danger is that managers in these companies may take advantage of this situation by stockpiling sufficient quantities of material or goods before a potential cutoff in order to have close to a zero stock-out probability. Such a policy, established without regard to the trade-offs involved, can be very costly. For example, "In Singapore possible curtailment in shipments of air conditioners led to such heavy advance ordering that for the next two years the market was completely saturated because the warehouses were full of air conditioners. Such an asymmetrical reward structure will distort the trade-offs involved. The profit performances of those managers who are receiving the benefits of additional inventory on hand should be adjusted to reflect the added costs of stockpiling.
It is obvious that as the probability of disruption increases or as holding costs go down, more inventories should be ordered. Similarly, if the cost of a stock-out rises or if future supplies are expected to be more expensive, it will pay to stockpile additional inventory. Conversely, if these parameters move in the opposite direction, fewer inventories should be stockpiled.
