Morningstar define the mid-cap growth category like this: Mid-growth funds invest in stocks medium-sized companies that are projected to grow faster than other mid-cap stocks. The market capitalization range for U.S. mid-caps typically falls between $1 billion and $8 billion and represents 20% of the total capitalization of the U.S. equity market. Growth is defined based on fast growth (high growth rates for earnings, sales, book value, and cash flow) and high valuations (high price ratios and low dividend yields).

The Market pricing is subject to change.

The bid-ask spread is the difference between the bid price for a security and its ask (or offer) price. It represents the difference between the highest price a buyer is willing to pay (bid) for a security and the lowest price a seller is willing to accept.

The net asset value (“NAV”) of the Fund’s shares is determined as of the close of regular trading on the NYSE (generally 4:00 p.m. Eastern time) each day the NYSE is open. Share are purchased and sold in secondary market transactions at negotiated market prices rather than at NAV. Shares of the Fund may be bought and sold throughout the day on the exchange through a brokerage account. However, shares are not individually redeemable, and may only be redeemed directly from the Fund by Authorized Participants in very large creation/redemption units. Shares may trade at, above or below NAV. Brokerage commissions will reduce returns.

Trailing Total Returns are shown net of fund management and operating expenses. For periods greater than one-year, average annual total returns are shown. Returns for periods shorter than one year are not annualized. The Russell Midcap® Growth Index measures the performance of the midcap growth segment of the US equity universe, as defined by Russell.

The performance data quoted represents past performance and does not guarantee future results. Current performance may be lower or higher. The investment return and principal of an investment will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. For performance as of the most recent month end, please call 1-800-617-0004. Short term performance, in particular, is not a good indication of a fund's future performance, and investments should not be made based solely on returns. Performance shown for less than a 1 year or less is cumulative.

The Premium/Discount information shows the difference between the daily market price of the Fund’s shares and the Fund’s net asset value (“NAV”). The daily market price is calculated using the mid-point between the highest bid and the lowest offer on the listing exchange, as of the time that the Fund’s NAV is calculated (usually 4:00 pm Eastern time). The vertical axis of the chart shows the premium or discount of the Mid-Point price as a percentage of the NAV. The horizontal axis shows the number of trading days covered by the chart, and each bar in the chart demonstrates how many days the Fund traded within the given premium/discount range. The data presented in the chart and table above represent past performance and cannot be used to predict future results.
