See “Sales Charges on Class A and Class C Shares” for discussion on how to qualify for a reduced sales charge. The Distributor may take recent redemptions into account in determining if an investment qualifies as a new investment.
2
For Class A investments under $1 million (under $500,000 for Bond Fund, ESG Core Bond Fund, Government Income Fund, High Yield Fund, Income Fund, Investment Grade Bond Fund, and under $250,000 on Short Duration Bond Fund, Short Duration Municipal Opportunities Fund, and Tax-Free Funds), a portion of the Selling Firm’s commission is paid out of the front-end sales charge.
3
Selling Firm commission, Rule 12b-1 service fee, and any underwriter fee percentages are calculated from different amounts, and therefore may not equal the total Selling Firm compensation percentages due to rounding, when combined using simple addition.
4
The Distributor retains the balance.
5
For purchases of Class A, Class R2, and Class R4 shares, beginning with the first year an investment is made, the Selling Firm receives an annual Rule 12b-1 service fee paid monthly in arrears. See “Distribution Agreements” for a description of Class A, Class R2, and Class R4 Rule 12b-1 Plan charges and payments.
6
Certain retirement platforms may invest in Class A shares without being subject to sales charges. Purchases via these platforms may pay a commission from the first dollar invested. Additionally, commissions (up to 1.00%) (up to 0.50% for Short Duration Bond Fund and Short Duration Municipal Opportunities Fund) are paid to dealers who initiate and are responsible for certain Class A share purchases not subject to sales charges. In both cases, the Selling Firm receives Rule 12b-1 fees in the first year as a percentage of the amount invested. After the first year, the Selling Firm receives Rule 12b-1 fees as a percentage of average daily net eligible assets paid monthly in arrears.
7
For Class C shares, the Selling Firm receives Rule 12b-1 fees in the first year as a percentage of the amount invested. After the first year, the Selling Firm receives Rule 12b-1 fees as a percentage of average daily net eligible assets paid monthly in arrears.
8
The Distributor may make a one-time payment at time of initial purchase out of its own resources to a Selling Firm that sells Class I shares of the funds. This payment may be up to 0.15% of the amount invested.
In addition, accordingly, the applicable information below is amended and restated as follows in the “Sales Charges on Class A and Class C Shares” section:
Deferred Sales Charge on Class A and Class C Shares
Class A shares are available with no front-end sales charge on investments of ($500,000 for Bond Fund, ESG Core Bond Fund, Government Income Fund, High Yield Fund, Income Fund, Investment Grade Bond Fund, and $250,000 for Short Duration Bond Fund, Short Duration Municipal Opportunities Fund, and Tax-Free Funds) or more. Class C shares are purchased at NAV without the imposition of an initial sales charge. In each of these cases, the funds will receive the full amount of the purchase payment. Also, see Appendix 1 to the Prospectus “Intermediary sales charge waivers,” for more information regarding the availability of sales charge waivers through particular intermediaries.
Contingent Deferred Sales Charge. There is a 1% CDSC on any Class A Tax-Free Fund shares upon which a commission or finder’s fee was paid that are sold within 18 months (0.75% for Bond Fund, ESG Core Bond Fund, Government Income Fund, High Yield Fund, Income Fund, Investment Grade Bond Fund, and 0.50% for Short Duration Bond Fund and Short Duration Municipal Opportunities Fund). Class C shares that are redeemed within one year of purchase will be subject to a CDSC at the rates set forth in the applicable Prospectus as a percentage of the dollar amount subject to the CDSC. The CDSC will be assessed on an amount equal to the lesser of the current market value or the original purchase cost of the Class A or Class C shares being redeemed. No CDSC will be imposed on increases in account value above the initial purchase prices or on shares derived from reinvestment of dividends or capital gains distributions.
In determining whether a CDSC applies to a redemption, the calculation will be determined in a manner that results in the lowest possible rate being charged. It will be assumed that a shareholder’s redemption comes first from shares the shareholder has held beyond the one year (18- month for Bond Fund, ESG Core Bond Fund, Government Income Fund, High Yield Fund, Income Fund, Investment Grade Bond Fund, Short Duration Bond Fund, Short Duration Municipal Opportunities Fund, and Tax-Free Funds) CDSC redemption period for Class A or one-year CDSC redemption period for Class C shares, or those the shareholder acquired through dividend and capital gain reinvestment. For this purpose, the amount of any increase in a share’s value above its initial purchase price is not subject to a CDSC. Thus, when a share that has appreciated in value is redeemed during the CDSC period, a CDSC is assessed only on its initial purchase price.
When requesting a redemption for a specific dollar amount, a shareholder should state if proceeds to equal the dollar amount requested are required. If not stated, only the specified dollar amount will be redeemed from the shareholder’s account and the proceeds will be less any applicable CDSC.
With respect to a CDSC imposed on a redemption of Class A shares, proceeds from the imposition of a CDSC are paid to the Distributor and are used in whole or in part by the Distributor to defray its expenses related to paying a commission or finder’s fee in connection with the purchase at NAV of Class A shares with a value of $500,000 (for Bond Fund, ESG Core Bond Fund, Government Income Fund, High Yield Fund, Income Fund, Investment Grade Bond Fund), and $250,000 (for Short Duration Bond Fund, Short Duration Municipal Opportunities Fund, and Tax-Free Funds) or more.
Furthermore, as a result, the applicable information below is amended and restated as follows in the “Sample Calculation of Maximum Offering Price” section:
Class A shares are sold with a maximum initial sales charge as set forth in the applicable prospectus. Class C shares are sold at NAV without any initial sales charges and with a 1.00% CDSC on shares redeemed within 12 months.
