Expense Example, Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

The following example is intended to help you compare the cost of investing in Emerging Markets Government Bond 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 Emerging Markets Government Bond ETF. This example assumes that Emerging Markets Government Bond 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy: rr_StrategyHeading Primary Investment Strategies
StrategyNarrative rr_StrategyNarrativeTextBlock

The Fund employs an indexing investment approach designed to track the performance of the Barclays USD Emerging Markets Government RIC Capped Index. This Index includes U.S. dollar-denominated bonds that have maturities longer than one year and that were issued by emerging market governments and government agencies, as well as government-owned corporations. The Index is capped, which means that its exposure to any particular bond issuer is limited to a maximum of 20%, and its aggregate exposure to issuers that individually constitute 5% or more of the Index is limited to 48%. If the Index, as constituted based on market weights, would exceed the 20% or 48% limit, the excess is reallocated to bonds of other issuers represented in the Index.

The Fund invests by sampling the Index, meaning that it holds a range of securities that, in the aggregate, approximates the full Index in terms of key risk factors and other characteristics. All of the Fund's investments will be selected through the sampling process, and at least 80% of the Fund's assets will be invested in bonds included in the Index. The Fund maintains a dollar-weighted average maturity consistent with that of the Index, which generally ranges between 10 and 15 years and, as of March 31, 2013, was 10.7 years.
Risk: rr_RiskHeading Primary Risks
Risk Narrative rr_RiskNarrativeTextBlock

An investment in the Fund could lose money over short or even long periods. The Fund is subject to the following risks, which could affect the Fund's performance:

Interest rate risk, which is the chance that bond prices will decline because of rising interest rates. Interest rate risk should be moderate for the Fund based on expected sensitivity of the portfolio to interest rate movement.

Income risk, which is the chance that the Fund's income will decline because of falling interest rates. Income risk should be moderate for the Fund, so investors should expect the Fund's monthly income to fluctuate accordingly.

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 issuer's ability to make such payments will cause the price of that bond to decline. Credit risk should be moderate for the Fund because it purchases investment-grade and below investment grade, (also known as high-yield or junk) bonds.

Emerging markets risk, which is the chance that the bonds of governments, government agencies, and government-owned corporations located in emerging markets will be substantially more volatile, and substantially less liquid, than the bonds of governments, government agencies, and government-owned corporations located in more developed foreign markets. Emerging markets risk should be high for the Fund.

Country/regional risk, which is the chance that world events-such as political upheaval, financial troubles, or natural disasters-will adversely affect the value of securities issued by foreign governments, government agencies, and government-owned corporations. Because the Fund may invest a large portion of its assets in bonds of issuers located in any one country or region, the Fund's performance may be hurt disproportionately by the poor performance of its investments in that area. Country/regional risk is especially high in emerging markets.

Nondiversification risk, which is the chance that the Fund's performance may be hurt disproportionately by the poor performance of bonds issued by just a few or even a single issuer. The Fund is considered nondiversified, which means that it may invest a significant percentage of its assets in bonds issued by a small number of issuers. Nondiversification risk for the Fund is high.

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 Fund's 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 Fund's ETF Shares are listed for trading on Nasdaq and are bought and sold on the secondary market at market prices. Athough 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 Fund's ETF Shares are listed for trading on Nasdaq, it is possible that an active trading market may not develop or be maintained.

Trading of the Fund's ETF Shares on Nasdaq may be halted by the activation of individual or marketwide 'circuit breakers' (which halt trading for a specified period of time when the price of a particular security or overall market prices decline by a specified percentage). Trading of the Fund's Bond 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 deem such action is appropriate in the interest of a fair and orderly market to protect investors.

A Note on Risk: Many investors invest in bonds and bond funds in an attempt to lower the overall risk of their portfolios. This strategy makes sense when the bonds owned are U.S. bonds because U.S. bond returns typically are not highly correlated with, and are far less volatile than, stock returns. The strategy is less likely to be effective, however, when bonds owned are emerging market bonds. Returns of emerging market bonds, even dollar-denominated bonds like those owned by the Fund, can be quite volatile, and tend to correlate more closely with U.S. and foreign stock returns than with U.S. bond returns. Consequently, if your goal is to lower risk and volatility, this Fund is not an appropriate investment.

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.
