The Manager will regularly consult with ?Macquarie Asset Management Credit Advisers US, LLC (Sub-advisor) to determine how much of the Funds assets to allocate among the different types of securities in which the Fund may invest based on the evaluation of economic and market conditions and the assessment of the returns and potential for appreciation that can be achieved from various sectors of the fixed income market. As part of this process, the Sub-advisor provides nondiscretionary recommendations to the Manager with respect to the Funds investments and executes trades on behalf of the Fund. The Funds investments may be variable- and floating-rate debt securities that generally pay interest at rates that adjust whenever a specified interest rate changes and/or reset on predetermined dates (such as the last day of a month or calendar quarter). Derivatives instruments may be utilized to effectively convert the fixed-rate interest payments from a group of certain Fund portfolio securities into floating-rate interest payments. The average portfolio duration (that is, the sensitivity to general changes in interest rates) of this Fund will generally not exceed one year. Up to 100% of the Funds total assets may be allocated to below-investment-grade securities within the Fund. Investments in emerging markets will, in the aggregate, be limited to no more than 15% of the Funds total assets. The Manager will limit non-US-dollar-denominated securities to no more than 50% of net assets, but total non-US-dollar currency exposure will be limited, in the aggregate, to no more than 25% of net assets. The Fund may also invest up to 20% of its total assets in a wide range of derivatives instruments, including forward foreign currency contracts, options, futures contracts, options on futures contracts, and swaps, for both hedging and nonhedging purposes. In addition, the Fund may hold a portion of its assets in cash or cash equivalents. 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. Show less
