The Fund allocates its investments principally among the following four sectors of the fixed income securities markets: the US investment grade sector, the US high yield sector, the international developed markets sector, and the emerging markets sector. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in fixed income securities (80% policy). The Fund’s investment manager, Delaware Management Company (Manager), will determine how much of the Fund’s assets to allocate to each of the four sectors, based on its evaluation of economic and market conditions, and its assessment of the returns and potential for appreciation that can be achieved from investments in each of the four sectors. The Manager will periodically reallocate the Fund’s assets as deemed necessary. In addition, the Manager may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited, Macquarie Investment Management Austria Kapitalanlage AG, and Macquarie Investment Management Global Limited (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 DMC believes it will be beneficial to utilize an Affiliated Sub-Advisor’s specialized market knowledge.

Under normal circumstances, between 5% and 35% of the Fund’s net assets will be allocated to the US high yield sector. The Fund’s investments in emerging markets will, in the aggregate, be limited to no more than 20% of the Fund’s net assets. The Fund will limit its investments in foreign securities to between 5% and 40% of its net assets and will seek to hedge its foreign currency exposure, which will be limited to 20% of the Fund’s net assets, by entering into forward foreign currency contracts.

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 invest in mortgage-backed securities and other asset-backed securities. The Fund may also use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, and swaps. The Fund will 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 effect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective.

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