Fund Description
As Putnam's flagship taxable income offering, the fund takes a flexible approach to pursuing high current income by diversifying across a range of fixed-income sectors. These sectors include, but are not limited to, investment-grade corporate bonds, mortgage-backed securities, U.S. Treasuries, and high-yield corporate bonds. The fund seeks to capitalize on those market sectors and maturities that appear to offer the best value at any given time.

Data is historical. Past performance is no guarantee of future results. More recent returns may be worth more or less than those shown. Investment return and principal value will fluctuate, and you may have a gain or loss when you sell your shares. For the most recent month-end performance, visit www.putnaminvestments.com.



Performance assumes reinvestment of distributions and does not account for taxes. Returns at public offering price (POP) for class A and class M shares reflect the current maximum initial sales charges of 5.25% and 3.25% for equity funds, and 3.75% and 3.25% for income funds (3.25% and 2.00% for Putnam Limited Duration Government Income Fund and Putnam Floating Rate Income Fund), respectively. POP performance of income funds' class A shares (other than Putnam Limited Duration Government Income Fund and Putnam Floating Rate Income Fund) and equity funds' class M shares reflects a reduction in maximum sales charge that took effect April 1, 2005. Class B share returns reflect the applicable contingent deferred sales charge (CDSC), which is 5% in the first year, declines to 1% in the sixth year, and is eliminated thereafter (except for Putnam Limited Duration Government Income Fund and Putnam Floating Rate Income Fund, which is 3% in the first year, declines to 1% in the fourth year, and is eliminated thereafter). Class C shares reflect a 1% CDSC the first year that is eliminated thereafter. Performance for class B, C, M, R, T, and Y shares prior to their inception is derived from the historical performance of class A shares, adjusted for the applicable sales charge (or CDSC) and, except for class Y shares, the higher operating expenses for such shares (with the exception of Putnam Tax-Free High Yield Fund and Putnam AMT-Free Insured Municipal Fund, which are based on the historical performance of class B shares). Class A, M, and T shares of Putnam money market funds have no initial sales charge. For a portion of the period some funds may have limited expenses or been sold on a limited basis with limited assets and expenses, without which returns would be lower. A short-term trading fee of up to 1% may apply.

The Lehman Aggregate Bond Index is an unmanaged index of U.S. investment-grade fixed-income securities. Securities in the fund do not match those in the indexes and performance of the fund will differ. It is not possible to invest directly in an index.

Lower rated bonds may offer higher yields in return for more risk. Mutual funds that invest in government securities in government securities are not guaranteed. Mortgage-backed securities are subject to prepayment risk.



The use of derivatives involves special risks and may result in losses.









You can lose money by investing in a fund. Any given fund may not achieve its goal, and is not intended as a complete investment program. All funds have risk. The value and/or returns of a portfolio will fluctuate with market conditions. You may have more or less than the original amount invested when you redeem your shares.
