Macquarie Investment Management Austria Kapitalanlage AG (MIMAK) serves as sub-advisor for the Fund. MIMAK is primarily responsible for the day-to-day management of the Fund's portfolio and determines it asset allocation. The Fund's investment manager, Delaware Management Company (Manager), may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited (MIMEL) and Macquarie Investment Management Global Limited (MIMGL). The Manager may also permit MIMEL, MIMGL, and Macquarie Funds Management Hong Kong Limited (MFMHKL) to execute Fund security trades on behalf of the Manager. The Manager may also permit MIMEL and MIMGL to exercise investment discretion for securities in certain markets where the Manager believes it will be beneficial to utilize their specialized market knowledge, and the Manager may also seek quantitative support from MIMGL. MIMGL is also responsible for managing real estate investment trust securities and other equity asset classes to which the portfolio managers may allocate assets from time to time.

Investing involves risk, including the possible loss of principal.

Fixed income securities and bond funds can lose value, and investors can lose principal, as interest rates rise. They also may be affected by economic conditions that hinder an issuer’s ability to make interest and principal payments on its debt.

The Fund may also be subject to prepayment risk, the risk that the principal of a bond that is held by a portfolio will be prepaid prior to maturity, at the time when interest rates are lower than what the bond was paying. A portfolio may then have to reinvest that money at a lower interest rate.

High yielding, non-investment-grade bonds (junk bonds) involve higher risk than investment grade bonds.

International investments entail risks including fluctuation in currency values, differences in accounting principles, or economic or political instability. Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility, lower trading volume, and higher risk of market closures. In many emerging markets, there is substantially less publicly available information and the available information may be incomplete or misleading. Legal claims are generally more difficult to pursue.

Investments in small and/or medium-sized companies typically exhibit greater risk and higher volatility than larger, more established companies.

REIT investments are subject to many of the risks associated with direct real estate ownership, including changes in economic conditions, credit risk, and interest rate fluctuations.

Risk controls and asset allocation models do not promise any level of performance or guarantee against loss of principal. Each [Fund] has a different level of risk.

An exchange-traded fund (ETF) is a security that represents all the stocks on a given exchange. ETF shares can be bought, sold, short-sold, traded on margin, and generally function as if they were stocks.

Liquidity risk is the possibility that securities cannot be readily sold within seven days at approximately the price at which a fund has valued them.

“Non-diversified” funds may allocate more of their net assets to investments in single securities than “diversified” funds. Resulting adverse effects may subject these funds to greater risks and volatility.

The Fund may invest in derivatives, which may involve additional expenses and are subject to risk, including the risk that an underlying security or securities index moves in the opposite direction from what the portfolio manager anticipated. A derivatives transaction depends upon the counterparties’ ability to fulfill their contractual obligations.

IBOR risk is the risk that changes related to the use of the London interbank offered rate (LIBOR) or similar rates (such as EONIA) could have adverse impacts on financial instruments that reference these rates. The abandonment of these rates and transition to alternative rates could affect the value and liquidity of instruments that reference them and could affect investment strategy performance.

Natural or environmental disasters, such as earthquakes, fires, floods, hurricanes, tsunamis, and other severe weather-related phenomena generally, and widespread disease, including pandemics and epidemics, have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Fund’s investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region are increasingly likely to adversely affect markets, issuers, and/or foreign exchange rates in other countries. These disruptions could prevent the Fund from executing advantageous investment decisions in a timely manner and could negatively impact the Fund’s ability to achieve its investment objective. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.
