--------------------------------------------------------------------------------

The following supplements any information to the contrary in the fund's summary
prospectus, prospectus and statement of additional information.


INTERMEDIARY DEFINED SALES CHARGE WAIVER POLICIES
The availability of certain sales charge waivers and discounts may depend on
whether you purchase and sell your shares directly from the fund or through a
financial intermediary. Specific intermediaries may have different policies and
procedures regarding the availability of front-end sales charge waivers or
contingent deferred (back-end) sales load (CDSC) waivers. In all instances, it
is your responsibility to notify the fund or your financial intermediary at the
time of purchase of any relationship or other facts qualifying you for sales
charge waivers or discounts. For waivers and discounts not available


through a particular intermediary, you will have to purchase fund shares
directly from the fund or through another intermediary to receive these waivers
or discounts. The following provides additional information about transactions
through the following intermediaries. References to Class C shares also refer
generally to Class C2 shares (if available).


EDWARD D. JONES & CO., L.P. ("EDWARD JONES")


POLICIES REGARDING TRANSACTIONS THROUGH EDWARD JONES
The following information has been provided by Edward Jones:

Effective on or after January 1, 2024, the following information supersedes
prior information with respect to transactions and positions held in fund
shares through an Edward Jones system. Clients of Edward Jones (also referred
to as "shareholders") purchasing fund shares on the Edward Jones commission and
fee-based platforms are eligible only for the following sales charge discounts
(also referred to as "breakpoints") and waivers, which can differ from
discounts and waivers described elsewhere in the mutual fund prospectus or
statement of additional information ("SAI") or through another broker-dealer.
In all instances, it is the shareholder's responsibility to inform Edward Jones
at the time of purchase of any relationship, holdings of Pioneer Funds or other
facts qualifying the purchaser for discounts or waivers. Edward Jones can ask
for documentation of such circumstance. Shareholders should contact Edward
Jones if they have questions regarding their eligibility for these discounts
and waivers.

BREAKPOINTS
o Breakpoint pricing, otherwise known as volume pricing, at dollar thresholds
  as described in the prospectus.

RIGHTS OF ACCUMULATION ("ROA")
o The applicable sales charge on a purchase of Class A shares is determined by
  taking into account all share classes (except certain money market funds and
  any assets held in group retirement plans) of Pioneer Funds held by the
  shareholder or in an account grouped by Edward Jones with other accounts for
  the purpose of providing certain pricing considerations ("pricing groups").
  If grouping assets as a shareholder, this includes all share classes held on
  the Edward Jones platform and/or held on another platform. The inclusion of
  eligible fund family assets in the ROA calculation is dependent on the
  shareholder notifying Edward Jones of such assets at the time of
  calculation. Money market funds are included only if such shares were sold
  with a sales charge at the time of purchase or acquired in exchange for
  shares purchased with a sales charge.


                                       2


o The employer maintaining a SEP IRA plan and/or SIMPLE IRA plan may elect to
  establish or change ROA for the IRA accounts associated with the plan to a
  plan-level grouping as opposed to including all share classes at a
  shareholder or pricing group level.
o ROA is determined by calculating the higher of cost minus redemptions or
  market value (current shares x NAV).

LETTER OF INTENT ("LOI")
o Through a LOI, shareholders can receive the sales charge and breakpoint
  discounts for purchases shareholders intend to make over a 13-month period
  from the date Edward Jones receives the LOI. The LOI is determined by
  calculating the higher of cost or market value of qualifying holdings at LOI
  initiation in combination with the value that the shareholder intends to buy
  over a 13-month period to calculate the front-end sales charge and any
  breakpoint discounts. Each purchase the shareholder makes during that
  13-month period will receive the sales charge and breakpoint discount that
  applies to the total amount. The inclusion of eligible fund family assets in
  the LOI calculation is dependent on the shareholder notifying Edward Jones
  of such assets at the time of calculation. Purchases made before the LOI is
  received by Edward Jones are not adjusted under the LOI and will not reduce
  the sales charge previously paid. Sales charges will be adjusted if LOI is
  not met.
o If the employer maintaining a SEP IRA plan and/or SIMPLE IRA plan has elected
  to establish or change ROA for the IRA accounts associated with the plan to
  a plan-level grouping, LOIs will also be at the plan-level and may only be
  established by the employer.

SALES CHARGE WAIVERS

Sales charges are waived for the following shareholders and in the following
situations:
o Associates of Edward Jones and its affiliates and other accounts in the same
  pricing group (as determined by Edward Jones under its policies and
  procedures) as the associate. This waiver will continue for the remainder of
  the associate's life if the associate retires from Edward Jones in
  good-standing and remains in good standing pursuant to Edward Jones'
  policies and procedures.
o Shares purchased in an Edward Jones fee-based program.
o Shares purchased through reinvestment of capital gains distributions and
  dividend reinvestment.
o Shares purchased from the proceeds of redeemed shares of the same fund family
  so long as the following conditions are met: the proceeds are from the sale
  of shares within 60 days of the purchase, the sale and purchase are made
  from a share class that charges a front load and one of the following:
  - The redemption and repurchase occur in the same account.

                                       3


  - The redemption proceeds are used to process an: IRA contribution, excess
    contributions, conversion, recharacterizing of contributions, or
    distribution, and the repurchase is done in an account within the same
    Edward Jones grouping for ROA.
o Shares exchanged into Class A shares from another share class so long as the
  exchange is into the same fund and was initiated at the discretion of Edward
  Jones. Edward Jones is responsible for any remaining CDSC due to the fund
  company, if applicable. Any future purchases are subject to the applicable
  sales charge as disclosed in the prospectus.
o Exchanges from Class C shares to Class A shares of the same fund, generally,
  in the 84th month following the anniversary of the purchase date or earlier
  at the discretion of Edward Jones.
o Purchases of Class 529-A shares through a rollover from either another
  education savings plan or a security used for qualified distributions.
o Purchases of Class 529 shares made for recontribution of refunded amounts.

CONTINGENT DEFERRED SALES CHARGE ("CDSC") WAIVERS

If the shareholder purchases shares that are subject to a CDSC and those shares
are redeemed before the CDSC is expired, the shareholder is responsible to pay
the CDSC except in the following conditions:
o The death or disability of the shareholder.
o Systematic withdrawals with up to 10% per year of the account value.
o Return of excess contributions from an Individual Retirement Account (IRA).
o Shares redeemed as part of a required minimum distribution for IRA and
  retirement accounts if the redemption is taken in or after the year the
  shareholder reaches qualified age based on applicable IRS regulations.
o Shares redeemed to pay Edward Jones fees or costs in such cases where the
  transaction is initiated by Edward Jones.
o Shares exchanged in an Edward Jones fee-based program.
o Shares acquired through NAV reinstatement.
o Shares redeemed at the discretion of Edward Jones for Minimum Balances, as
  described below.

EXCHANGING SHARE CLASSES
o At any time it deems necessary, Edward Jones has the authority to exchange at
  NAV a shareholder's holdings in a fund to Class A shares of the same fund.


MERRILL LYNCH
Purchases or sales of front-end (i.e. Class A) or level-load (i.e. Class C)
mutual fund shares through a Merrill platform or account will be eligible only
for the following sales load waivers (front-end, contingent deferred, or
back-end waivers) and discounts, which differ from those disclosed elsewhere in
this Fund's prospectus. Purchasers will have to buy mutual fund shares directly
from the mutual fund company or through another intermediary to be eligible for
waivers or discounts not listed below.

It is the client's responsibility to notify Merrill at the time of purchase or
sale of any relationship or other facts that qualify the transaction for a
waiver or discount. A Merrill representative may ask for reasonable
documentation of such facts and Merrill may condition the granting of a waiver
or discount on the timely receipt of such documentation.

Additional information on waivers and discounts is available in the Merrill
Sales Load Waiver and Discounts Supplement (the "Merrill SLWD Supplement") and
in the Mutual Fund Investing at Merrill pamphlet at ml.com/funds. Clients are
encouraged to review these documents and speak with their financial advisor to
determine whether a transaction is eligible for a waiver or discount.


FRONT-END LOAD WAIVERS AVAILABLE AT MERRILL

  retirement, deferred compensation, and employee benefit plans (including
