| The Core Fixed Income ETF will seek to achieve its investment objective through exposure to a broad portfolio of U.S. and foreign investment grade fixed income securities. The Portfolio may invest in obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, including mortgage-backed securities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, money market funds, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. The Portfolio may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the to-be-announced (TBA) market. As a non-fundamental policy, under normal circumstances, at least 80% of the Portfolio s net assets will be invested in fixed income securities considered to be investment grade quality. |
