Delaware Floating Rate II Fund**(formerly, First Investors Floating Rate Fund)

*The Fund changed its broad-based securities index to the S&P/LSTA Leveraged Loan Index as of Oct. 4, 2019. The Fund elected to use the new index because it more closely reflected the Fund’s investment strategies.

**Updated Significant Fund Event. On April 6, 2019, Foresters Investment Management Company, Inc. (FIMCO), the investment adviser to the First Investors Funds, entered into an agreement with Macquarie Management Holdings, Inc. (MMHI), whereby MMHI, on behalf of its affiliate Delaware Management Company (DMC), a series of Macquarie Investment Management Business Trust (MIMBT), would acquire FIMCO’s asset management business (the “Transaction”). In connection with the Transaction, the Board of Trustees of the First Investors Trusts and the First Investors Fund shareholders approved, pursuant to an Agreement and Plan of Reorganization (the “Agreement”), the transfer of all assets and liabilities of each First Investors Fund to a corresponding, newly formed fund in the Delaware Funds by Macquarie family of funds. The Transaction closed on Oct. 4, 2019.

The Fund's investment manager, Delaware Management Company (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.

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.

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.

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.

The high yield secondary market is particularly susceptible to liquidity problems when institutional investors, such as mutual funds and certain other financial institutions, temporarily stop buying bonds for regulatory, financial, or other reasons. In addition, a less liquid secondary market makes it more difficult for the Fund to obtain precise valuations of the high yield securities in its portfolio.

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.

LIBOR risk is the risk that potential changes related to the use of the London Interbank Offered Rate (LIBOR) could have adverse impacts on financial instruments which reference LIBOR. The potential abandonment of LIBOR could affect the value and liquidity of instruments which reference LIBOR.

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.
