Past performance is no guarantee of future results. The performance data quoted represents past performance. Current performance may be lower or higher than the performance data quoted. Total return includes change in share prices and, in each case, includes reinvestment of dividends and capital gain distributions. The investment return and principal value vary so that an investor’s shares, when redeemed, may be worth more or less than the original cost.

Yield is the annual rate of return of an investment paid in dividends or interest, expressed as a percentage. A snapshot of a fund’s interest and dividend income, yield is expressed as a percentage of a fund’s net asset value, is based on income earned over a certain time period and is annualized, or projected, for the coming year.
Duration is a measure of the sensitivity of the price of a bond or other debt instrument to a change in interest rates. The Bloomberg U.S. Aggregate Bond Index is a broad-based benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market. The index includes Treasurys, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid ARM pass-throughs), asset-backed securities and commercial mortgage-backed securities (agency and non-agency). This index is unmanaged and investors cannot invest directly in this index.
Investing involves risk; principal loss is possible. There is no guarantee the Fund’s investment objective will be achieved. The Oakmark Bond Fund invests primarily in a diversified portfolio of bonds and other fixed-income securities. These include, but are not limited to, investment grade corporate bonds; U.S. or non-U.S.-government and government-related obligations (such as, U.S. Treasury securities); below investment-grade corporate bonds; agency mortgage backed-securities; commercial mortgage- and asset-backed securities; senior loans (such as, leveraged loans, bank loans, covenant lite loans, and/or floating rate loans); assignments; restricted securities (e.g., Rule 144A securities); and other fixed and floating rate instruments. The Fund may invest up to 20% of its assets in equity securities, such as common stocks and preferred stocks. The Fund may also hold cash or short-term debt securities from time to time and for temporary defensive purposes.
Under normal market conditions, the Fund invests at least 25% of its assets in investment-grade fixed-income securities and may invest up to 35% of its assets in below investment-grade fixed-income securities (commonly known as “high-yield” or “junk bonds”).
Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments. Bond values fluctuate in price so the value of your investment can go down depending on market conditions. These and other risk considerations such are described in detail in the Fund’s prospectus.
