*The Fund's secondary benchmark, the ICE BofA US Corporate, Government & Mortgage Index was removed as of Oct. 4, 2019.

**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, Macquarie Investment Management Global Limited (MIMGL), and Macquarie Funds Management Hong Kong Limited (MFMHKL) (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 the Manager believes it will be beneficial to utilize an Affiliated Sub-Advisor's specialized market knowledge. The Manager may permit its affiliates, MIMGL and MFMHKL, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL.

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 not ordinarily associated with US investments including fluctuation in currency values, differences in accounting principles, or economic or political instability in other nations. Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility and lower trading volume.

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.

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.

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.

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.
