The Fund's investment manager, Delaware Management Company (Manager), may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited (MIMEL), Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), and Macquarie Investment Management Global Limited (MIMGL) (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.

Investing involves risk, including the possible loss of principal.

Fixed income securities can lose value, including the possible loss of principal. An issuer of a fixed income security may be unable to make interest payments and/or repay principal in a timely manner. The prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes.

The principal on a fixed income security may be prepaid prior to maturity, which may require reinvestment at a lower interest rate.

High yield securities (“junk bonds”) are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than higher-rated securities.

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.

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.

Because the Fund may invest in bank loans and other direct indebtedness, it is subject to the risk that the Fund will not receive payment of principal, interest, and other amounts due in connection with these investments, which primarily depend on the financial condition of the borrower and the lending institution.

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.
