1 For Class A shares, a 1% contingent deferred sales charge (CDSC) is only imposed on certain Class A shares that are purchased at net asset value (NAV) for $1 million or more that are subsequently redeemed within 18 months of purchase. For Class C shares, a 1% CDSC applies to redemptions within 12 months of purchase.
2 “Other expenses” account for Class R6 shares not being subject to certain expenses as described further in the section of the Prospectus entitled “Choosing a share class.”
3 The Fund's investment manager, Delaware Management Company (Manager), has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any 12b-1 fees, acquired fund fees and expenses, taxes, interest, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations) in order to prevent total annual fund operating expenses from exceeding 0.42% of the Fund's average daily net assets for all share classes other than Class R6, and 0.33% of the Fund's Class R6 shares' average daily net assets, from July 26, 2024 through February 26, 2026. These waivers and reimbursements may only be terminated by agreement of the Manager and the Fund.

Effective the date of this Supplement, the section of the Fund’s summary prospectus entitled, “Fund summary — Delaware Diversified Income Fund — Example?” is deleted in its entirety and is replaced with the following:

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. In addition, the example shows expenses for Class C shares, assuming those shares were not redeemed at the end of those periods. The example also assumes that your investment has a 5% return each year and reflects the Manager’s expense waivers and reimbursements for the contractual period and the total operating expenses without waivers for years 2 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class A   (if not
redeemed)
C		   C   R   Inst.   R6  

1 year

   $515     $145     $245     $94     $43     $34  

3 years

   $696     $492     $492     $336     $178     $150  

5 years

   $892     $862     $862     $598     $326     $276  

10 years

   $1,457     $1,905     $1,905     $1,345     $755     $646  

Because everyone’s tax situation is unique, you should consult your tax professional about federal, state, local, or foreign tax consequences before making an investment in the Fund or acting on a distribution check (if applicable).
