EXAMPLE
This example translates the "total annual fund operating
expenses" shown in the preceding table into dollar amounts. By
doing this, you can more easily compare the cost of investing
in a fund to the cost of investing in other mutual funds. The
example makes certain assumptions. It assumes that you invest
$10,000 in a fund for the time periods shown and, except as
stated, redeem all your shares at the end of those periods. It
also assumes a 5% return on your investment each year and that
the fund's operating expenses remain the same. The example is
hypothetical; your actual costs and returns may be higher or
lower.

THE SECTION "HOW DO I BUY FUND SHARES?" IS REPLACED BY THE
FOLLOWING (EXCEPT FOR THE TABLES OF CLASS A AND CLASS M
INITIAL SALES CHARGES AND CLASS A AND CLASS B DEFERRED SALES
CHARGES, WHICH REMAIN UNCHANGED):

HOW DO I BUY FUND SHARES?
You can open a fund account with as little as $500 and make
additional investments at any time with as little as $50. Each
fund sells its shares at the offering price, which is the NAV
plus any applicable sales charge. Your financial advisor or
Putnam Investor Services generally must receive your completed
buy order before the close of regular trading on the New York
Stock Exchange for your shares to be bought at that day's
offering price.
YOU CAN BUY SHARES
O    THROUGH A FINANCIAL ADVISOR Your advisor will be
responsible for furnishing all necessary documents to Putnam
Investor Services, and may charge you for his or her services.
O    THROUGH SYSTEMATIC INVESTING You can make regular
investments of $25 or more per month through automatic
deductions from your bank checking or savings account.
Application forms are available through your advisor or Putnam
Investor Services at 1-800-225-1581.
You may also complete an order form and write a check for the
amount you wish to invest, payable to the fund. Return the
check and completed form to Putnam Mutual Funds.
Each fund may periodically close to new purchases of shares or
refuse any order to buy shares if the fund determines that
doing so would be in the best interests of the fund and its
shareholders.
WHICH CLASS OF SHARES IS BEST FOR ME?
This prospectus offers you a choice of four classes of fund
shares: A, B, C, and M. This allows you to choose among
different types of sales charges and different levels of
ongoing operating expenses, as illustrated in the "Fees and
expenses" section. The class of shares that is best for you
depends on a number of factors, including the amount you plan
to invest and how long you plan to hold the shares. Here is a
summary of the differences among the classes of shares:
CLASS A SHARES
O    Initial sales charge of up to 5.75%
O    Lower sales charge for investments of $50,000 or more
O    No deferred sales charge (except on certain redemptions
of shares bought without an initial sales charge)
O    Lower annual expenses, and higher dividends, than class
B, C or M shares because of lower 12b-1 fee

CLASS B SHARES
O    No initial sales charge; your entire investment goes to
work for you
O    Deferred sales charge of up to 5% if you sell shares
within 6 years after you bought them
O    Higher annual expenses, and lower dividends, than class A
or M shares because of higher 12b-1 fee
O    Convert automatically to class A shares after 8 years,
reducing the future 12b-1 fee (may convert sooner in some
cases)
O    Orders for class B shares for more than $250,000 are
treated as orders for class A shares or refused

CLASS C SHARES
O    No initial sales charge; your entire investment goes to
work for you
O    Deferred sales charge of up to 1.00% if you sell shares
within one year after you bought them
O    Higher annual expenses, and lower dividends, than class A
or M shares because of higher 12b-1 fee
O    No conversion to class A shares, so future 12b-1 fee does
not decrease
O    Orders of $1,000,000 or more and orders which because of
a right of accumulation or statement of intent
would qualify for the purchase of class A shares without an
initial sales charge will be treated as orders for class A
shares or declined

CLASS M SHARES
O    Initial sales charge of up to 3.50%
O    Lower sales charges for larger investments of $50,000 or
more
O    No deferred sales charge
O    Lower annual expenses, and higher dividends, than class B
or C shares because of lower 12b-1 fee
O    Higher annual expenses, and lower dividends, than class A
shares because of higher 12b-1 fee
O    No conversion to class A shares, so future 12b-1 fee does
not decrease

O    YOU MAY BE ELIGIBLE FOR REDUCTIONS AND WAIVERS OF SALES
CHARGES. Sales charges may be reduced or waived under certain
circumstances and for certain groups. Information about
reductions and waivers of sales charges is included in the
SAI. You may consult your financial advisor or Putnam Mutual
Funds for assistance.
O    DISTRIBUTION (12B-1) PLANS. Each fund has adopted
distribution plans to pay for the marketing of fund shares and
for services provided to shareholders. The plans provide for
payments at annual rates (based on average net assets) of up
to 0.35% on class A shares and 1.00% on class B, class C and
class M shares. The Trustees currently limit payments on class
A and class M shares to 0.25% and 0.75% (0.50% for High Yield
Trust II, American Government Income Fund and U.S. Government
Income Trust) of average net assets, respectively. Because
these fees are paid out of each fund's assets on an ongoing
basis, the higher fees for class B, class C and class M shares
will increase the cost of your investment over time and may
cost you more than paying the initial sales charge for class A
shares. Because class C and class M shares, unlike class B
shares, do not convert to class A shares, class C and class M
shares may cost you more over time than class B shares.
