Strategy Narrative [Text Block]
The fund is one of three Putnam Dynamic Asset Allocation Funds, each of which has a unique strategic, or typical, allocation between equity and fixed-income investments. Using qualitative analysis and quantitative techniques, the Investment Manager adjusts portfolio allocations from time to time within a certain range for each fund to try to optimize a fund’s performance consistent with its goal. The strategic allocation and the range of allowable allocation for the fund are shown below.
Class    Strategic Allocation    Range  
Equity
   30%    15-45%  
Fixed Income
   70%    55-85%  
The fund invests mainly in fixed-income investments, including U.S. and foreign government obligations, corporate obligations and securitized debt instruments (such as mortgage-backed investments). The Investment Manager may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell fixed-income investments. The fund also invests, to a lesser extent, in equity securities (growth or value stocks or both) of U.S. and foreign companies of any size. The Investment Manager may consider, among other factors, a company’s valuation, financial strength, growth potential, competitive position in its industry, projected future earnings, cash flows and dividends when deciding whether to buy or sell equity investments. The Investment Manager may also select other investments that do not fall within these asset classes. The fund typically uses to a significant extent derivatives, such as futures, options, certain foreign currency transactions, warrants and interest rate and total return swap contracts, for both hedging and non-hedging purposes.
The fund may invest directly or indirectly through its wholly-owned and controlled Subsidiary, which like the fund, is advised by the Investment Manager. The fund may invest no more than 25% of its assets in the Subsidiary. Currently, the fund does not expect to invest significantly in the Subsidiary. The Subsidiary will invest primarily in commodity futures and swaps on commodity futures, but it may also invest in other commodity-related instruments (such as financial futures, option and swap contracts) or other asset classes (including through derivatives). Unlike the fund, the Subsidiary may invest without limitation in commodity-related instruments. Unless indicated otherwise, references to the fund’s investments, investment exposures or risks include its indirect investments, investment exposures and risks through the Subsidiary.
