The Fund seeks to achieve the Investment Objective by investing the majority of its assets in a diversified portfolio of U.S. commercial mortgage-backed securities (CMBS). CMBS are structured debt securities, typically secured by diversified pools of mortgages on commercial real estate properties located across the U.S. While the Fund will primarily invest in CMBS, it may also invest in unsecured bonds issued by companies primarily engaged in a real estate or real estate related business. The CMBS and unsecured bonds may include Rule 144a securities. The Fund may use certain financial derivative instruments (FDI) for investment purposes.
