The following supplements any information to the contrary in each 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 one
intermediary.

JANNEY MONTGOMERY SCOTT

Effective May 1, 2020, if you purchase fund shares through a Janney Montgomery
Scott LLC ("Janney") brokerage account, you will be eligible for the following
load waivers (front-end sales charge waivers and contingent deferred sales
charge ("CDSC"), or back-end sales charge, waivers) and discounts, which may
differ from those disclosed elsewhere in this fund's prospectus or statement of
additional information.

FRONT-END SALES CHARGE* WAIVERS ON CLASS A SHARES AVAILABLE AT JANNEY
o Shares purchased through reinvestment of capital gains distributions and
  dividend reinvestment when purchasing shares of the same fund (but not any
  other fund within the fund family).
o Shares purchased by employees and registered representatives of Janney or its
  affiliates and their family members as designated by Janney.
o Shares purchased from the proceeds of redemptions within the same fund
  family, provided (1) the repurchase occurs within ninety (90) days following
  the redemption, (2) the redemption and purchase occur in the same account,
  and (3) redeemed shares were subject to a front-end or deferred sales load
  (i.e., right of reinstatement).
o Employer-sponsored retirement plans (e.g., 401(k) plans, 457 plans,
  employer-sponsored 403(b) plans, profit sharing and money purchase pension
  plans and defined benefit plans). For purposes of this provision,
  employer-sponsored retirement plans do not include SEP IRAs, Simple IRAs,
  SAR-SEPs or Keogh plans.
o Shares acquired through a right of reinstatement.
o Class C shares that are no longer subject to a contingent deferred sales
  charge and are converted to Class A shares of the same fund pursuant to
  Janney's policies and procedures.

CDSC WAIVERS ON CLASS A AND C SHARES AVAILABLE AT JANNEY
o Shares sold upon the death or disability of the shareholder.

                                       2


o Shares sold as part of a systematic withdrawal plan as described in the
  fund's prospectus.
o Shares purchased in connection with a return of excess contributions from an
  IRA account.
o Shares sold as part of a required minimum distribution for IRA and other
  retirement accounts due to the shareholder reaching age 70 1/2 as described
  in the fund's prospectus.
o Shares sold to pay Janney fees but only if the transaction is initiated by
  Janney.
o Shares acquired through a right of reinstatement.
o Shares exchanged into the same share class of a different fund.

FRONT-END SALES CHARGE* DISCOUNTS AVAILABLE AT JANNEY: BREAKPOINTS, RIGHTS OF
ACCUMULATION, AND/OR LETTERS OF INTENT
o Breakpoints as described in the fund's prospectus.
o Rights of accumulation ("ROA"), which entitle shareholders to breakpoint
  discounts, will be automatically calculated based on the aggregated holding
  of fund family assets held by accounts within the purchaser's household at
  Janney. Eligible fund family assets not held at Janney may be included in
  the ROA calculation only if the shareholder notifies his or her financial
  advisor about such assets.
o Letters of intent which allow for breakpoint discounts based on anticipated
  purchases within a fund family, over a 13-month time period. Eligible fund
  family assets not held at Janney Montgomery Scott may be included in the
  calculation of letters of intent only if the shareholder notifies his or her
  financial advisor about such assets.
