Inflation, sometimes referred to as headline inflation, reflects rising prices for consumer goods and services, or equivalently, a declining value of money. Core inflation excludes food and energy prices, which tend to be volatile. It is the opposite of deflation (see Deflation).

Investments in fixed income securities are subject to the risks associated with debt securities including credit, price and interest rate risk.

In certain interest rate environments, such as when real interest rates are rising faster than nominal interest rates, inflation-protected securities with similar durations may experience greater losses than other fixed income securities. Interest payments on inflation-protected debt securities will fluctuate as the principal and/or interest is adjusted for inflation and can be unpredictable.

The prospectus contains very important information about the characteristics of the underlying security and potential tax implications of owning this fund.

Please see the prospectus for details about sales charges.

The gross expense ratio is the fund's total annual operating costs, expressed as a percentage of the fund's average net assets for a given time period. It is gross of any fee waivers or expense reimbursement. The net expense ratio is the expense ratio after the application of any waivers or reimbursement. This is the actual ratio that investors paid during the fund's most recent fiscal year. Please see the prospectus for more information.

1 Treasury inflation-protected securities (TIPS)

TIPS are a special type of U.S. Treasury security designed to address a fundamental, long-standing fixed-income market issue: that the fixed interest payments and principal values at maturity of most fixed-income securities don't adjust for inflation. TIPS interest payments and principal values do. The adjustments include upward or downward changes to both principal and coupon interest based on inflation. TIPS are inflation-indexed; that is, tied to the U.S. government's Consumer Price Index (CPI). At maturity, TIPS are guaranteed by the U.S. government to return at least their initial $1,000 principal value, or that principal value adjusted for inflation, whichever amount is greater. In addition, as their principal values are adjusted for inflation, their interest payments also adjust.

2 Securitized issues

Securitized issues consist of contractual debt obligations such as residential mortgages, auto loans or credit card debt (among others). Cash flows from these debt obligations are packaged as securities and sold to investors.

3 Inflation-linked swap

A derivative where an income stream that is tied to the rate of inflation is exchanged for an income stream with a fixed interest rate.
