Putnam Income Fund 

The fund invests mainly in bonds that are securitized debt instruments (such as mortgage-backed investments) and other obligations of companies and governments worldwide denominated in U.S. dollars or (to a lesser extent) foreign currencies, are either investment-grade or below-investment-grade in quality (sometimes referred to as "junk bonds") and have intermediate- to long-term maturities (three years or longer). The manager typically uses to a significant extent derivatives, such as futures, options and swap contracts, for both hedging and non-hedging purposes.
