International Finance Multiple Currency Transaction Exposure
Estimate Net CFs in Each Currency Example: This American company has exposure in four foreign currencies over the next quarter.
Weight the Dollar Cash Flows Pound 15 15/16 = .9375 Can. $ 8 8/16 = .5 S. Krona -15 -15/16 = -.9375 Peso 8 8/16 = .5 . 16 1.0 Note that there is an expected net cash inflow of $16 million. But what is its standard deviation?
Estimate Volatility (standard deviation) of XR Movements over the Quarter British Pound – 2.8% Canadian Dollar – 2.7% Swedish Krona – 3.2% Mexican Peso – 3.5%

Determine the Portfolio Standard Deviation Variance = sum of cells in wtd. var/cov matrix = .00076536 Standard Deviation = Square Root of Variance = 2.7665%
Determine Possible Cash Flow Expected Value = $16 million Minus One S.D. = $15.557 million Minus Two S.D. = $15.115 million Plus One S.D. = $16.443 million Plus Two S.D. = $16.885 million Now decide if you want to hedge this risk
