Short-Term Financing 10
Solution to Supplemental Case: Flyer Company
a. The optimal portfolio is dependent on your degree of risk aversion. By converting the information in
the table above into 4 bar charts (showing the probability distribution), one above another, you can
review the risk-return tradeoff.
By using a spreadsheet format, the percentage changes in exchange rates can be easily computed.
Using these percentage changes along with the interest rates, the effective financing rate can be
computed for each currency under each scenario. The effective financing rates are provided below for
each scenario, along with the expected value of the effective financing rate (using the probabilities
assigned to each scenario):
Somewhat Expected Value
Strong $ Stable $ Weak $ of Effective
Currency Scenario Scenario Scenario Financ ing Rate
Australian dollar –0.56% 14.51% 28.07% 14.05%
British pound 4.56 14.48 21.10 13.49
Canadian dollar 9.71 9.71 17.45 12.03
Japanese yen –1.00 11.60 29.60 13.22
Mexican peso –8.18 13.47 18.06 8.35
New Zealand dollar –5.48 5.22 12.35 4.14
Singapore dollar –4.60 1.76 10.24 2.40

Each portfolio’s effective financing rates are determined as a sum of weighted effective financing rates
under each scenario.
