Investment approach
The investment seeks to provide current income and real (after inflation) total returns.
The fund invests primarily in inflation-indexed bonds of varying maturities issued by the U.S. and non-U.S. governments, their agencies or instrumentalities, and U.S. and non-U.S. corporations. Under normal circumstances, the fund maintains an average portfolio duration that is within ±20% of the duration of the Bloomberg U.S. Treasury Inflation Protected Securities (“TIPS”) Index. The fund is not managed to a particular maturity.

In situations where the net and gross fund expense figures are different, the investment manager has contractually agreed to limit the investment option's expense. Differences may also be shown due to the investment manager choosing to pay certain expenses that would normally be payable by the fund. The gross fund expense figure does not reflect any waivers or caps on the mutual fund. Performance shown reflects the application of net expenses of the fund.
