Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in US and foreign debt securities, including those in emerging markets (80% policy). Debt securities include all varieties of fixed, variable and floating rate income securities, including bonds, US and foreign government and agency securities, corporate loans (and loan participations), and mortgage-backed securities and other asset-backed securities. To achieve the Fund's investment objectives, the Manager will allocate investments among various sectors of debt securities and at any given time may have a substantial amount of its assets invested in any class of debt security.

In addition, the Manager may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), Macquarie Investment Management Europe Limited (MIMEL), and Macquarie Investment Management Global Limited (MIMGL) (together, the “Affiliated Sub-Advisors”). The Manager may also permit these Affiliated Sub-Advisors to execute Fund security trades on behalf of the Manager and exercise investment discretion for securities in certain markets where the Manager believes it will be beneficial to utilize an Affiliated Sub-Advisor's specialized market knowledge.

The Fund may invest up to 100% of its net assets in high yield, lower-quality debt securities (also known as “junk bonds”).

The Fund may invest up to 100% of its net assets in foreign securities, including emerging markets securities. The Fund’s total non-US dollar currency exposure may reach 100% of net assets. Due to the manner in which the Fund is managed, it may be subject to a high rate of portfolio turnover.

The Fund may hold a substantial portion of its assets in cash or short-term fixed income obligations in unusual market conditions to meet redemption requests, for temporary defensive purposes, and pending investment. The Fund may also use a wide range of derivatives instruments, typically including forward foreign currency contracts, options, futures contracts, options on futures contracts, and swaps. The Fund may use derivatives for both hedging and nonhedging purposes. For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return; and index swaps to enhance return or to affect diversification.

The 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change.
