Statement of Additional Information Supplement	February 1, 2018

SUPPLEMENT TO THE STATEMENT OF ADDITIONAL INFORMATION OF ALL PUTNAM RETAIL OPEN-END FUNDS

Effective immediately, sub-section “Sales Charges and Other Share Class Features—Retail Investors—Purchases of class A and class T1 shares without an initial sales charge” in the section “HOW TO BUY FUND SHARES” is replaced with the following:

Purchases of class A and class T1 shares without an initial sales charge. Class A shares of any Putnam fund (other than Putnam Short Duration Income Fund, Putnam Government Money Market Fund, and Putnam Money Market Fund) purchased by retail investors on or after March 1, 2018 that are not subject to an initial sales charge (in accordance with the schedules stated above) are subject to a CDSC of 1.00% if redeemed before the first day of the month in which the twelve-month anniversary of that purchase occurs. Class A shares of any Putnam fund (other than Putnam Short Duration Income Fund, Putnam Government Money Market Fund, and Putnam Money Market Fund) purchased by retail investors prior to March 1, 2018 that are not subject to an initial sales charge (in accordance with the schedules stated above) are subject to a CDSC of 1.00% if redeemed before the first day of the month in which the nine-month anniversary of that purchase occurs. Class A shares of Putnam Short Duration Income Fund, Putnam Money Market Fund and Putnam Government Money Market Fund purchased by retail investors on or after March 1, 2018 by exchanging shares from another Putnam fund that were not subject to an initial sales charge (in accordance with the schedules stated above) are subject to a CDSC of 1.00% if redeemed before the first day of the month in which the twelve-month anniversary of the original purchase occurs. Class A shares of Putnam Short Duration Income Fund, Putnam Money Market Fund and Putnam Government Money Market Fund purchased by retail investors prior to March 1, 2018 by exchanging shares from another Putnam fund that were not subject to an initial sales charge (in accordance with the schedules stated above) are subject to a CDSC of 1.00% if redeemed before the first day of the month in which the nine-month anniversary of the original purchase occurs. Class T1 shares of Putnam Money Market Fund and Putnam Government Money Market Fund purchased by retail investors by exchanging shares from another Putnam fund that were not subject to an initial sales charge (in accordance with the schedules stated above) are subject to a CDSC of 1.00% if redeemed before the first day of the month in which the nine-month anniversary of the original purchase occurs.

The CDSC assessed on redemptions of fewer than all of an investor’s class A shares (and, for Putnam Money Market Fund and Putnam Government Money Market Fund, class T1 shares) subject to a CDSC will be based on the amount of the redemption minus the amount of any appreciation on the investor’s CDSC-subject shares since the purchase of such shares. The CDSC assessed on full redemptions of CDSC-subject shares will be

based on the lower of the shares’ cost and current NAV. Putnam Retail Management will retain any CDSC imposed on redemptions of such shares to compensate it for the up-front commissions paid to financial intermediaries for such share sales.

Effective April 1, 2018, the following is added as a sub-section under “Sales Charges and Other Share Class Features—Retail Investors” in the section “HOW TO BUY FUND SHARES:”

Conversion of class C shares into class A shares. Class C shares will automatically convert to class A shares on or around the end of the month ten years after the purchase date, provided that the fund or the financial intermediary through which a shareholder purchased class C shares has records verifying that the class C shares have been held for at least ten years, and that class A shares are available for purchase by residents in the shareholder’s jurisdiction. Group retirement plan recordkeeping platforms of certain broker-dealer intermediaries who hold class C shares with the fund in an omnibus account do not track participant level share lot aging. These class C shares would not satisfy the conditions for the conversion. Class C shares acquired by exchanging class C shares of another Putnam fund will convert to class A shares based on the time of the initial purchase. Any CDSC for such shares will be calculated using the schedule of the fund into or from which shares have been exchanged that would result in the highest CDSC applicable to such shares. Class C shares acquired through reinvestment of distributions will convert to class A shares based on the date of the initial purchase to which such shares relate. For this purpose, class C shares acquired through reinvestment of distributions will be attributed to particular purchases of class C shares in accordance with such procedures as the Trustees may determine from time to time. The conversion of class C shares to class A shares is subject to the condition that such conversions will not constitute taxable events for federal tax purposes. Shareholders should consult with their tax advisers regarding the state and local tax consequences of the conversion of class C shares to class A shares, or any other exchange or conversion of shares.

Effective March 1, 2018, the sub-section “Exchange Privilege—Same-Fund Exchange Privilege” in the section “INVESTOR SERVICES” is replaced with the following:
