Under CIMA F3 (Financial Strategy), sensitivity of operating profit to exchange-rate movements is assessed using transaction exposure: where revenues/costs are denominated in a foreign currency, the home-currency value of those cash flows changes when the exchange rate moves. Because all four companies have the same total revenue and cost levels in K$, the company whose net EUR cash flow is largest (in absolute terms) will have the greatest potential impact on operating profit growth when the EUR/K$ rate changes.

Treat exports as EUR inflows and imports as EUR outflows. Compute each company’s net EUR position:

Company A: EUR exports 20 − EUR imports 10 = +10 (net EUR receivable)

Company B: EUR exports 18 − EUR imports 0 = +18 (net EUR receivable)

Company C: EUR exports 21 − EUR imports 25 = −4 (net EUR payable)

Company D: EUR exports 0 − EUR imports 15 = −15 (net EUR payable)

Now compare absolute exposures: |+10|, |+18|, |−4|, |−15| ⇒ largest is 18 for Company B. Therefore, Company B’s operating profit (and hence its year-on-year growth objective) is most sensitive to movements in the EUR/K$ exchange rate, because the K$ value of its EUR-denominated net inflows will vary the most as rates change.
