    Performance

    Average annual returns
    (as of )

    Important disclosure

    The results shown represent past performance; past performance does not guarantee future results. Current performance may be lower or higher than the past performance shown. Share price, principal value, and return will vary, and you may have a gain or a loss when you sell your shares. Current performance may be lower or higher than the performance data quoted.

    Performance returns assume the reinvestment of all distributions. Returns for periods less than one year are not annualized. Total returns reflect a contractual expense limitation for direct annual Fund expenses for all classes for certain periods since inception, without which returns would have been lower. Pre-inception historical performance for newer share classes is based on the corresponding share class performance of a Fund's predecessor fund. If no predecessor Fund applies, historical performance is based on that of the longest existing share class, adjusted for sales charges if applicable.

    Fund risks

    The Fund seeks to match the performance of an index. Correlation between Fund performance and index performance may be affected by Fund expenses, index composition changes, and the timing of Fund share purchases and redemptions. The Fund is subject to the risks of investing in equity securities (including mid-sized companies). Smaller companies are usually less stable in price and less liquid than larger, more established companies. Smaller companies are more vulnerable than larger companies to adverse business and economic developments and may have more limited resources. Therefore, they generally involve greater risk. The Fund may become non-diversified as a result of a change in relative market capitalization or index weighting of one or more constituents in the S&P Midcap 400® Index, the Index the Fund is seeking to match. Please refer to the most recent prospectus for a more detailed explanation of the Fund's principal risks.

    Read this important information

    Performance represents average annual total returns, assumes the reinvestment of all distributions and reflects applicable sales charges. Total returns reflect a waiver of part of each Fund's fees for certain periods since inception, without which returns would have been lower. Average annual total returns illustrate the annual compounded returns that would have produced the cumulative total return if each Fund's performance had remained constant throughout the period indicated. Returns for periods less than one year are not annualized.

    Additional disclosures

    Returns prior to the first offering of a specific share class of a Fund are based on the previous performance of other share classes of that Fund as noted below. This performance is substantially similar to what the specific share class would have produced because all share classes of a Fund invest in the same portfolio of securities. Performance assumes the reinvestment of all dividends and distributions. Performance has not been adjusted to reflect differences in applicable sales charges for individual classes, which if reflected may have resulted in higher or lower performance for the specific share class. Performance has been adjusted to reflect different expense levels for individual classes.

    Morningstar Ratings disclosure

    Morningstar Ratings reflect risk-adjusted performance. The Morningstar RatingTM is derived from a weighted average of the performance figures associated with the Fund's 3-, 5- and 10-year (if applicable) periods.

    Morningstar Ratings metrics: Morningstar Ratings are based solely on a proprietary mathematical formula based on measures of risk and performance that it recalculates each month. The ratings formula measures the amount of variation in a fund's monthly performance (excluding the effects of sales charges and loads) emphasizing downward variations and rewarding consistency. Ratings are subject to change every month. The top 10% of funds in the category receive 5 stars; the next 22.5%, 4 stars; the next 35%, 3 stars; the next 22.5%, 2 stars; and the bottom 10%, 1 star.

    Ratings are based on specific class performance of each fund. Current fund performance may be higher or lower, which may change a fund's star rating. Despite high ratings, funds may have experienced negative performance during the period. Performance may reflect a waiver of part of a fund's fees for certain periods since inception, without which returns would have been lower. The Morningstar Rating does not include any adjustment for sales loads.
