contextRef="v_ETF_S000038501">&lt;p&gt;The following example is intended to help you compare the cost of investing in Short-Term Inflation-Protected Securities ETF with the cost of investing in other funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in Short-Term Inflation-Protected Securities ETF. This example assumes that Short-Term Inflation-Protected Securities ETF provides a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period.

contextRef="v_ETF_S000038501">&lt;p&gt;The Fund is designed for investors with a low tolerance for risk, but you could still lose money by investing in it. The Fund's performance could be hurt by:&lt;/p&gt;&lt;p&gt;Income fluctuations. The Fund's quarterly income distributions are likely to fluctuate considerably more than the income distributions of a typical bond fund. Income fluctuations associated with changes in interest rates are expected to be low; however, income fluctuations associated with changes in inflation are expected to be high. Overall, investors can expect income fluctuations to be high for the Fund.&lt;/p&gt;&lt;p&gt;Interest rate risk, which is the chance that the value of a bond will fluctuate due to a change in the level of interest rates. Although inflation-indexed bonds seek to provide inflation protection, their prices may decline when interest rates rise and vice versa. Because the Fund's dollar-weighted average maturity is expected to be five years or less, interest rate risk is expected to be low for the Fund.&lt;/p&gt;&lt;p&gt;Because ETF Shares are traded on an exchange, they are subject to additional risks:&lt;/p&gt;&lt;p&gt;Short-Term Inflation-Protected Securities 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 a Short-Term Inflation-Protected Securities 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 Short-Term Inflation-Protected Securities ETF Shares on the secondary market, and you may receive more or less than NAV when you sell those shares.&lt;/p&gt;&lt;p&gt;Although Short-Term Inflation-Protected Securities ETF Shares are listed for trading on Nasdaq, it is possible that an active trading market may not develop or be maintained.&lt;/p&gt;&lt;p&gt;Trading of Short-Term Inflation-Protected Securities 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 Short-Term Inflation-Protected Securities ETF Shares may also be halted if (1) the shares are delisted from Nasdaq without first being listed on another exchange or (2) exchange officials determine that such action is appropriate in the interest of a fair and orderly market or to protect investors.&lt;/p&gt;&lt;p&gt;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.&lt;/p&gt;</rr:RiskNarrativeTextBlock>

contextRef="v_Retail_S000038501">&lt;p&gt;The following examples are intended to help you compare the cost of investing in the Fund's Investor Shares or Admiral Shares with the cost of investing in other mutual funds. They illustrate the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund's shares. These examples assume that the Shares provide a return of 5% a year and that total annual fund operating expenses remain as stated in the preceding table. The results apply whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:&lt;/p&gt;</rr:ExpenseExampleNarrativeTextBlock>

<rr:PortfolioTurnoverTextBlock
contextRef="v_Retail_S000038501">&lt;p&gt;The Fund pays transaction costs, such as commissions, when it buys and sells securities (or 'turns over' its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense examples, reduce the Fund's performance. The Fund has no operating history and therefore has no portfolio turnover information.

<rr:RiskNarrativeTextBlock
contextRef="v_Retail_S000038501">&lt;p&gt;The Fund is designed for investors with a low tolerance for risk, but you could still lose money by investing in it. The Fund's performance could be hurt by:&lt;/p&gt;&lt;p&gt;Income fluctuations. The Fund's quarterly income distributions are likely to fluctuate considerably more than the income distributions of a typical bond fund. Income fluctuations associated with changes in interest rates are expected to be low; however, income fluctuations associated with changes in inflation are expected to be high. Overall, investors can expect income fluctuations to be high for the Fund.&lt;/p&gt;&lt;p&gt;Interest rate risk, which is the chance that the value of a bond will fluctuate due to a change in the level of interest rates. Although inflation-indexed bonds seek to provide inflation protection, their prices may decline when interest rates rise and vice versa. Because the Fund's dollar-weighted average maturity is expected to be five years or less, interest rate risk is expected to be low for the Fund.&lt;/p&gt;&lt;p&gt;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.&lt;/p&gt;</rr:RiskNarrativeTextBlock>
