          Credit quality as of 09/30/2025
Total may not equal 100% due to rounding. The Fund’s investment manager, Delaware Management Company (DMC) receives “Credit Quality” ratings for the underlying securities held by the Fund from three “nationally recognized statistical rating organizations” (NRSROs) — Standard & Poor’s (S&P), Moody’s Investors Service, and Fitch, Inc. The credit quality breakdown is calculated by DMC based on the NSRO ratings and the index credit quality rules. For securities rated by an NRSRO other than S&P, that rating is converted to the equivalent S&P credit rating. Securities that are unrated by any of the three NRSROs are included in the “not rated” category when applicable. Unrated securities do not necessarily indicate low quality. More information about securities ratings is contained in the Fund’s Statement of Additional Information.

Distributions ($ per share)
  
  
  1If a Fund makes a distribution from any source other than net income, it is required to
          provide shareholders with a notice disclosing the source of such distribution (each a "Notice"). The
          amounts and sources of distributions reported above and in each Notice are only estimates and are not
          provided for tax reporting purposes. Each Fund will send each shareholder a Form 1099 DIV for the
          calendar year that will provide definitive information on how to report the Fund's distributions for
          federal income tax purposes. The information in the table above will not be updated to reflect any
          subsequent recharacterization of dividends and distributions. Click here to see recent
          Notices pertaining to the Fund (if any).
        
  2Information on return of capital distributions (if any) is only provided from June 1, 2014 onward.
    
  3Includes both short- and long-term capital gains.
