The performance data quoted above represents past performance. Past performance is not a guarantee of future results. Performance may be lower or higher than performance data quoted. Index performance is for illustrative purposes only and does not represent actual Fund performance. One cannot invest directly in an index. Performance data for the Index assumes reinvestment of dividends and is net of the management fees for the Index's components, as applicable, but it does not reflect management fees, transaction costs or other expenses that you would pay if you invested in the Fund directly. Results prior to an Index component's existence as an ETF are based on its underlying index, which do not reflect underlying management fees.
Fund shares are not individually redeemable and will be issued and redeemed at their NAV only through certain authorized broker-dealers in large, specified blocks of shares called "creation units", and otherwise, can be bought and sold only through exchange trading. Creation units are issued and redeemed principally in-kind.
Shares are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Total Returns are calculated using the daily 4:00 pm ET net asset value (NAV). Since May 31, 2016, the price used to calculate the market price returns ("MP") is the mean between the day's last bid and ask prices on the fund's primary exchange. Any market price returns prior to May 31, 2016 were calculated using the day's closing price on the fund's primary exchange. The market price returns do not represent returns an investor would receive if shares were traded at other times.
The Morningstar Rating™ for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance (this does not include the effects of sales charges, loads, and redemption fees). The top 10% of products in each product category receive 5stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods.
