Primary Risks
An investment in the Fund could lose money over short or even long periods. You should expect the Funds share price and total return to fluctuate within a wide range, like the fluctuations of the overall bond market. The Fund is subject to the following risks, which could affect the Funds performance:
Interest rate risk
, which is the chance that bond prices overall will decline because of rising interest rates. Interest rate risk should be moderate for the Fund because it invests primarily in short- and intermediate-term bonds, whose prices are less sensitive to interest rate changes than are the prices of long-term bonds.
Credit risk,
which is the chance that a bond issuer will fail to pay interest and principal in a timely manner, or that negative perceptions of the issuers ability to make such payments will cause the price of that bond to decline. Credit risk should be moderate for the Fund.
Income risk
, which is the chance that the Funds income will decline because of falling interest rates. Income risk is generally moderate for intermediate-term bond funds, so investors should expect the Funds monthly income to fluctuate accordingly.
Index sampling risk,
which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Funds target index. Index sampling risk for the Fund should be low.
Because ETF Shares are traded on an exchange, they are subject to additional risks:
The Funds ETF Shares are listed for trading on Nasdaq and are bought and sold on the secondary market at market prices. Although it is expected that the market price of an ETF Share typically will approximate its net asset value (NAV), there may be times when the market price and the NAV differ significantly. Thus, you may pay more or less than NAV when you buy ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.
Although the Funds ETF Shares are listed for trading on Nasdaq, it is possible that an active trading market may not be maintained.
Trading of the Funds ETF Shares on Nasdaq may be halted by the activation of individual or marketwide circuit breakers (which halt trading for a specific period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Funds ETF Shares may also be halted if (1) the shares are delisted from Nasdaq without first being listed on another exchange or (2) Nasdaq officials determine that such action is appropriate in the interest of a fair and orderly market or for the protection of investors.
An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Actual after-tax returns depend on your tax situation and may differ from those shown in the preceding table. When after-tax returns are calculated, it is assumed that the shareholder was in the highest individual federal marginal income tax bracket at the time of each distribution of income or capital gains or upon redemption. State and local income taxes are not reflected in the calculations. Please note that after-tax returns are not relevant for a shareholder who holds fund shares in a tax-deferred account, such as an individual retirement account or a 401(k) plan. Also, figures captioned
Return After Taxes on Distributions and Sale of Fund Shares
will be higher than other figures for the same period if a capital loss occurs upon redemption and results in an assumed tax deduction for the shareholder.
