The NAV Return is based on the NAV of the fund, and the Market Price Return is based on the market price per share of the fund. The price used to calculate market return (Market Price) is determined using the Official Closing Price on the primary stock exchange (generally, 4:00 p.m. Eastern time) and may not represent the returns you would receive if shares were traded at other times. Market Price and NAV returns assume that dividends and capital gain distributions have been reinvested in the fund at Market Price and NAV, respectively. 3 The fund’s performance relative to the index may be affected by fair-value pricing and timing differences in foreign exchange calculations. 4 The net version of the index reflects reinvested dividends net of withholding taxes but reflects no deductions for expenses or other taxes. 5 In anticipation of new regulatory requirements, the fund’s regulatory index has changed from the Russell RAFI™ Developed ex US Large Company Index (Net) to the MSCI EAFE ® Index (Net).

| [1]ETF performance must be shown based on both a market price and NAV basis. The fund’s per share NAV is the value of one share of the fund. NAV is calculated by taking the fund’s total assets (including the fair value of securities owned), subtracting liabilities, and dividing by the number of shares outstanding. The NAV Return is based on the NAV of the fund, and the Market Price Return is based on the market price per share of the fund. The price used to calculate market return (Market Price) is determined using the Official Closing Price on the primary stock exchange (generally, 4:00 p.m. Eastern time) and may not represent the returns you would receive if shares were traded at other times. Market Price and NAV returns assume that dividends and capital gain distributions have been reinvested in the fund at Market Price and NAV, respectively.[2]Performance does not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption or sale of fund shares.[3]The fund’s performance relative to the index may be affected by fair-value pricing and timing differences in foreign exchange calculations.[4]In anticipation of new regulatory requirements, the fund’s regulatory index has changed from the Russell RAFI™ Emerging Markets Large Company Index (Net) to the MSCI Emerging Markets Index (Net).
