The Series seeks to generate income by investing primarily in dividend paying companies. The Series may also invest in real estate investment trusts (REITs) and income-generating equity securities. REITs are pooled investment vehicles that invest primarily in income-producing real estate or real estate-related loans or interests. Macquarie Investment Management Global Limited (MIMGL), an affiliate of the Series' investment manager, Delaware Management Company (Manager), serves as the Series' sub-advisor and manages the Series' assets. In addition, Macquarie Funds Management Hong Kong Limited, an affiliate of the Manager, may execute security trades for the Series. Using a systematic bottom-up approach, the Series seeks to select securities that have above-average yields coupled with a demonstrated business quality, as seen thought superior profitability, balance sheet strength, earnings stability and corporate sustainability. Stocks also need to have reasonable company valuations relative to their current growth prospects, and their peer group.
