Recommending a short term foreign investment

Suppose the treasurer of your company finds out you are enrolled in BUS450 International Finance. Knowing this, your treasurer seeks your advice. Your company has extra cash reserves of $100,000,000 and needs to invest it for 6 months. The treasurer has heard that investing in foreign currencies for the short term might have a higher yield when compared to a short term United States investment.

I am not sure how to even go about approaching this assignment, any suggestion would be helpful.
