Supplement to the current Statutory Prospectus for each Fund

Effective immediately, the following is added to the "Investment manager" sub-section of the "Who manages the Fund" section of each Fund's Statutory Prospectus:

On September 19, 2024, the US Securities and Exchange Commission (SEC) announced that Macquarie Investment Management Business Trust (MIMBT), of which Delaware Management Company (Manager) is a series, had entered into a settlement agreement with the SEC consenting to an order (Settlement Order) relating to a legacy investment strategy, the Absolute Return Mortgage-Backed Securities Strategy (ARMBS Strategy). MIMBT no longer offers the ARMBS Strategy. MIMBT agreed to the Settlement Order without admitting or denying the SEC's findings.

Under the Settlement Order, the SEC found that, between January 2017 and April 2021 (Period): (i) MIMBT valued certain collateralized mortgage-backed obligations (CMOs) at inflated prices; (ii) MIMBT executed dealer-interposed and internal cross trades of those CMOs between registered investment company clients and other clients at prices that deviated from market prices; (iii) certain disclosures of MIMBT relating to performance, valuation, liquidity and cross trading contained false and misleading statements and omissions; and (iv) MIMBT failed to implement policies and procedures relating to valuation, conflicts of interest and cross trades. The matters involved in the settlement pre-dated the launch of the Funds and did not concern the Manager's services to the Funds.

As part of the settlement, MIMBT was ordered to cease and desist from committing or causing any violations of certain statutory provisions and SEC rules. A copy of the Settlement Order is available on the SEC's website at https://www.sec.gov/files/litigation/admin/2024/ia-6709.pdf.

MIMBT has been ordered to pay a civil penalty to the SEC, as well as disgorgement of management fees in respect of certain impacted accounts relating to the Period and interest.

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 a Fund or acting on a distribution check (if applicable).
