Example

The following example is intended to help you compare the cost of investing in the Fund’s Admiral Shares with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invest $10,000 in the Fund’s shares. This example assumes 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:


1 Year	3 Years
$20	$64

Portfolio Turnover

The Fund has no operating history and therefore has no portfolio turnover information.

Primary Investment Strategies

The Fund invests primarily in U.S. and foreign stocks that are expected to generate low volatility relative to the global equity market. The portfolio will include a diverse mix of companies located in many different countries and representing many different market sectors and industry groups. The advisor uses quantitative models that evaluate all of the securities in the Fund’s benchmark, the FTSE Global All Cap Index (USD Hedged), to construct a global equity portfolio that seeks to achieve the lowest amount of expected volatility subject to a set of reasonable constraints designed to foster portfolio diversification and liquidity. The Fund generally will seek to hedge most of its currency exposure back to the U.S. dollar to reduce overall portfolio volatility.

Primary Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range, like the fluctuations of global stock markets. The Fund is subject to the following risks, which could affect the Fund’s performance:

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, investments in foreign stocks can be riskier than U.S. stock investments. The prices of foreign stocks and the prices of U.S. stocks have, at times, moved in opposite directions.

• 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 companies in foreign countries or regions. Because the Fund may invest a large portion of its assets in securities of companies 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.

• Currency risk and currency hedging risk. The Fund generally will seek to hedge most of its currency exposure back to the U.S. dollar to reduce overall portfolio volatility. However, not all currency exposure will be hedged, so the Fund will have a low level of currency risk. Currency risk is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates. The Fund will also have a low level of currency hedging risk, which is the risk that the currency hedging transactions entered into by the Fund may not perfectly offset the Fund’s foreign currency exposure. For example, the Fund will decline in value if it underhedges a currency that has weakened or overhedges a currency that has strengthened relative to the U.S. dollar.

• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

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.
