In May 1997, George Soros started shorting the Thai Baht for the U.S. dollar with a forward contract. As a result, the Thai Baht exchange rate moved from 23 Bahts per dollar (May 1, 1997) to 41 Bahts per dollar (May 31, 1997) in a month. If George Soros had a short position of 9,000,000 Bahts forward contract at forward rate F1(Baht/$)=43 on May 1,1997, then his profit/loss in the forward trading would be $ on May 31,1997. (Please keep the sign and two decimal places.)
