The Glover Scholastic Aid Foundation has received a 20 million global government bond portfolio from a Greek donor. This bond portfolio will be held in euros and managed separately from Glover's existing U.S. dollar-denominated assets. Although the bond portfolio is currently unhedged, the portfolio manager, Raine Sofia, is investigating various alternatives to hedge the currency risk of the portfolio. The bond portfolio's current allocation and the relevant country performance data are given in Exhibits 1 and 2. Historical correlations for the currencies being considered by Sofia are given in Exhibit 3. Sofia expects that future returns and correlations will be approximately equal to those given in Exhibits 2 and 3. ed Exhibit 1.
