The Global Credit ETF seeks to maximize total returns primarily from a universe of U.S. and foreign corporate debt securities that mature within twenty years from the date of settlement. In addition, the Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, bank obligations, commercial paper, repurchase agreements, money market funds, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Advisor expects that the Portfolio will primarily invest in the obligations of issuers that are in developed countries.
