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.
