Currency of denomination versus currency of determination

One of the central concepts of modern international corporate finance is the distinction between the currency in which cash flows are denominated and the currency that determines the size of the cash flows. In the example in the previous section, it does not matter whether, as a matter of business practice, the firm may contract, be invoiced in, and pay for each individual shipment in its own local currency. If foreign exporters do not provide price concessions, the cash outflow of the importer behaves just like a foreign currency cash flow; even though payments are made in local currency, they occur in greater amounts. As a result, the cash flow, even while denominated in local currency, is determined by the relative value of the foreign currency. The functional currency concept introduced in FAS 52 is similar to the "currency of determination" -- but not exactly. The currency of determination refers to revenue and operating expense flows, respectively; the functional currency concept pertains to an entity as a whole, and is, therefore, less precise.
To complicate things further, the currency of recording, that is, the currency in which the accounting records are kept, is yet another matter. For example, any debt contracted by the firm in foreign currency will always be recorded in the currency of the country where the corporate entity is located. However, the value of its legal obligation is established in the currency in which the contract is denominated. An example of the importance of these distinctions may be found in Exhibit 5.
It is possible, therefore, that a firm selling in export markets may record assets and liabilities in its local currency and invoice periodic shipments in a foreign currency and yet, if prices in the market are dominated by transactions in a third country, the cash flows received may behave as if they were in that third currency. To illustrate: a Brazilian firm selling coffee to West Germany may keep its records in cruzeiros, invoice in German marks, and have DM-denominated receivables, and physically collect DM cash flow, only to find that its revenue stream behaves as if it were in U.S. dollars! This occurs because DM-prices for each consecutive shipment are adjusted to reflect world market prices which, in turn, tend to be determined in U.S. dollars. The significance of this distinction is that the currency of denomination is (relatively) readily subject to management discretion, through the choice of invoicing currency. Prices and cash flows, however, are determined by competitive conditions which are beyond the immediate control of the firm.
Yet an additional dimension of exchange risk involves the element of time. In the very short run, virtually all local currency prices for real goods and services (although not necessarily for financial assets) remain unchanged after an unexpected exchange rate change. However, over a longer period of time, prices and costs move inversely to spot rate changes; the tendency is for Purchasing Power Parity and the Law of One Price to hold.
In reality, this price adjustment process takes place over a great variety of time patterns. These patterns depend not only on the products involved, but also on market structure, the nature of competition, general business conditions, government policies such as price controls, and a number of other factors. Considerable work has been done on the phenomenon of "pass-through" of price changes caused by (unexpected) exchange rate changes. And yet, because all the factors that determine the extent and speed of pass-through are very firm-specific and can be analyzed only on a case-by-case basis at the level of the operating entity of the firm (or strategic business unit), generalizations remain difficult to make. Exhibit 6 summarizes the firm-specific effects of exchange rate changes on operating cash flows.
Conceptually, though, it is important to determine the time frame within which the firm cannot react to (unexpected) rate changes by (1) raising prices; (2) changing markets for inputs and outputs; and/or (3) adjusting production and sales volumes. Sometimes, at least one of these reactions is possible within a relatively short time; at other times the firm is "locked-in" through contractual or strategic commitments extending considerably into the future. Indeed, those firms which are free to react instantaneously and fully to adverse (unexpected) rate changes are not subject to exchange risk.
A further implication of the time-frame element is that exchange risk stems from the firm's position when its cash flows are, for a significant period, exposed to (unexpected) exchange rate changes, rather than the risk resulting from any specific international involvement. Thus, companies engaged purely in domestic transactions but who have dominant foreign competitors may feel the effect of exchange rate changes in their cash flows as much or even more than some firms that are actively engaged in exports, imports, or foreign direct investment.
