7. Global NPV: Walmart is considering purchasing a discount retail chain in Brazil. Discount the following Brazilian real (the "real" is the brazilian currency) cash flows using forecasted IRP exchange rates. Use a discount rate of 15%. After 5 years the cashflows will grow at a constant perpetual rate. Estimate 5 years of FCFF and then apply a growth perpetuity to compute FCF from 6 to infinity.
