The Portfolio allocates its investments principally among the following three sectors of the fixed income securities markets: the US investment grade sector, the US high yield sector, and the international sector. Under normal circumstances, the Portfolio will invest at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities (80% Policy). The Portfolio’s 80% Policy may be changed without shareholder approval. However, shareholders will be given notice at least 60 days prior to any such change.

The Manager will determine how much of the Portfolio to allocate to each of the three 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 three sectors. The Manager will periodically reallocate the Portfolio’s assets, as deemed necessary. The relative proportion of the Portfolio’s assets to be allocated among sectors is described below.

·US investment grade sector Under normal circumstances, between 50% and 100% of the Portfolio’s total assets will be invested in the US investment grade sector. In managing the Portfolio’s assets allocated to the US investment grade sector, the Manager will invest principally in debt obligations issued or guaranteed by the US government, its agencies, or instrumentalities, and by US corporations. The corporate debt obligations in which the Portfolio may invest include bonds, notes, debentures, and commercial paper of US companies. The US government securities in which the Portfolio may invest include a variety of securities that are issued or guaranteed as to the payment of principal and interest by the US government, and by various agencies or instrumentalities that have been established or sponsored by the US government. 

The US investment grade sector of the Portfolio’s assets may also be invested in mortgage-backed securities (MBS) issued or guaranteed by the US government, its agencies, or instrumentalities or by government-sponsored corporations. Other MBS in which the Portfolio may invest are issued by certain private, nongovernment entities. Subject to the quality limitations, the Portfolio may also invest in securities that are backed by assets such as receivables on home equity and credit card loans, automobile, mobile home, recreational vehicle, and other loans, wholesale dealer floor plans, and leases.

Securities purchased by the Portfolio within this sector will be rated in one of the four highest rating categories or will be unrated securities that the Manager determines are of comparable quality.

·US high yield sector Under normal circumstances, up to 30% of the Portfolio’s total assets will be allocated to the high yield sector. The Manager will invest the Portfolio’s assets that are allocated to the high yield sector primarily in those securities having a liberal and consistent yield and those tending to reduce the risk of market fluctuations. The Portfolio may invest in corporate debt obligations, including, notes, which may be convertible or nonconvertible, commercial paper, units consisting of bonds with stock or warrants to buy stock attached, debentures, convertible debentures, zero-coupon bonds, and PIK securities. 

The Portfolio will invest in both rated and unrated bonds. The rated bonds that the Portfolio may purchase in this sector will generally be rated lower than BBB- by S&P, Baa3 by Moody’s, or similarly rated by another NRSRO.

·International sector The Portfolio may invest up to 30% of its total assets in the international sector. The international sector invests primarily in fixed income securities of issuers organized or having a majority of their assets or deriving a majority of their operating income in foreign countries. These fixed income securities include foreign government securities, debt obligations of foreign companies, and securities issued by supranational entities. A supranational entity is an entity established or financially supported by the national governments of one or more countries to promote reconstruction or development. Examples of supranational entities include, among others, the International Bank for Reconstruction and Development (more commonly known as the World Bank), the European Economic Community, the European Investment Bank, the Inter-American Development Bank, and the Asian Development Bank. 

The Portfolio may invest in securities issued in any currency and may hold foreign currencies. Securities of issuers within a given country may be denominated in the currency of another country or in multinational currency units, such as the euro. The Portfolio may, from time to time, purchase or sell foreign currencies and/or engage in forward foreign currency transactions in order to expedite settlement of Portfolio transactions and to minimize currency value fluctuations. Currency considerations carry a special risk for the Portfolio to the extent that it allocates a significant portion of its assets to foreign securities.

The Portfolio will invest in both rated and unrated foreign securities. It may purchase securities of issuers in any foreign country, developed and underdeveloped. These investments may include direct obligations of issuers located in emerging markets countries.

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.

The Portfolio’s total non-US dollar currency exposure will be limited, in aggregate, to no more than 10% of net assets, and the Portfolio’s investments in emerging markets securities will be limited to no more than 15% of the Portfolio’s net assets.

The Portfolio 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 Portfolio may also use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, and swaps. The Portfolio will use derivatives for both hedging and nonhedging purposes. For example, the Portfolio 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 Portfolio will not use derivatives for reasons inconsistent with its investment objective.

The Portfolio may invest in privately placed securities, including those that are eligible for resale only among certain institutional buyers without registration, which are commonly known as “Rule 144A Securities.” Restricted securities that are determined to be illiquid may not exceed the Portfolio’s limit on investments in illiquid investments.
