To seek to provide investment results that closely correspond, before fees and expenses, to the performance of the Morningstar^® US Dividend Enhanced Select Index^SM (the Underlying Index).

The following table describes the fees and expenses that you will incur if you buy, hold and sell shares of the Fund. You may also incur other fees, such as usual and customary brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and the Example that follows.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Under normal market conditions, the Fund invests at least 80% of its assets in the component securities of the Underlying Index. The Underlying Index is a systematic, rules-based proprietary index that is maintained and calculated by Morningstar, Inc. (Morningstar or Index Provider). The Underlying Index is based on the Morningstar^® US Target Market Exposure Index (Parent Index) and is constructed by applying an optimization process to the Parent Index that aims to deliver a higher dividend yield than the Parent Index, while limiting expected tracking error to the Parent Index (i.e., to provide a “dividend tilt” through the selection and weighting of securities from the Parent Index), as described in greater detail below. The Parent Index includes large- and mid-capitalization stocks representing the top 85% of the investable universe (i.e., U.S. equity market) by float-adjusted market capitalization (“float-adjusted” means that only shares that are estimated to be publicly available to investors are included in the calculation of market capitalization). The Underlying Index is governed by published, objective rules for security selection, exclusion, rebalancing and adjustments for corporate actions. The Underlying Index is reconstituted quarterly.

In particular, the construction process for the Underlying Index includes a security selection and weighting process that aims to deliver a higher dividend yield than the Parent Index (with “dividend yield” calculated based on trailing twelve-month dividend yield) while limiting expected tracking error to the Parent Index through an optimization process that is applied at each quarterly reconstitution of the Underlying Index. Eligible stocks (i.e., those included in the Parent Index) are fed into an “optimizer” that selects and weights stocks in a manner that seeks to maximize the portfolio’s dividend yield (calculated as described above), subject to several constraints, such as those for individual stock and sector weightings, to try to limit expected tracking error relative to the Parent Index, and portfolio turnover. At each quarterly reconstitution of the Underlying Index: (i) individual stock weightings are capped at the lesser of (a) three times their weighting in the Parent Index or (b) their weighting in the Parent Index plus 0.5%; (ii) after the optimization process is applied, stocks must have a minimum weighting of 0.005% to be included in the Underlying Index; (iii) sector weightings are kept within 5% of their

weightings in the Parent Index; and (iv) the one-way turnover of the Underlying Index is capped at 10% (this portfolio turnover constraint may be relaxed if an optimal portfolio solution is not feasible).

As the Underlying Index is a “Core Dividend Tilt Index” that is designed to provide a “dividend tilt” by seeking to deliver a higher dividend yield than the Parent Index while at the same time providing “core” exposure to the U.S. equity market through the tracking error and other constraints described above, the Underlying Index includes certain stocks that do not currently pay dividends (in other words, the application of the tracking error and other constraints as part of the index methodology security selection process results in certain non-dividend paying stocks being included in the Underlying Index). The Underlying Index may include large- and mid-capitalization companies. As of May 31, 2025, the Underlying Index was comprised of 284 securities with capitalizations ranging from $5.78 billion to $3.42 trillion.

The Fund, using a “passive” or indexing investment approach, seeks investment results that closely correspond, before fees and expenses, to the performance of the Underlying Index. The Fund may use either a replication strategy or representative sampling strategy. Under a replication strategy, the Fund will replicate the component securities of the Underlying Index as closely as possible (i.e., invest in all of the component securities in their respective weightings in the Underlying Index). However, it may not be possible or practicable to replicate the Underlying Index. In these circumstances, the Fund may use a representative sampling strategy whereby the Fund will invest in what it believes to be a representative sample of the component securities of the Underlying Index, but may not track the Underlying Index with the same degree of accuracy as would an investment vehicle replicating the entire Underlying Index. Under the representative sampling technique, the investment manager will select securities that collectively have an investment profile similar to that of the Underlying Index, including securities that resemble those included in the Underlying Index in terms of risk factors, performance attributes and other characteristics, such as market capitalization and industry weightings. The Fund’s portfolio is generally reconstituted quarterly following the quarterly reconstitution of the Underlying Index.

The Fund may invest in equity futures (including equity index futures) and equity total return swaps to provide additional opportunities to add value and better track the performance of the Fund’s Underlying index, such as to equitize cash and accrued income (i.e., gain equity market exposure and maintain liquidity until the Fund invests in individual securities), simulate investments in the Underlying Index, facilitate trading or minimize transaction costs.

The Fund will concentrate its investments (i.e., hold 25% or more of its net assets) in a particular industry or group of industries to approximately the same extent that

the Underlying Index is concentrated. As of May 31, 2025, the Underlying Index was concentrated in the information technology sector.

Principal Risks

You could lose money by investing in the Fund. Exchange-traded fund (ETF) shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value (NAV), trading price, yield, total return and ability to meet its investment goal.

Market: The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise. In addition, the value of the Fund’s investments may go up or down due to general market or other conditions that are not specifically related to a particular issuer, such as: real or perceived adverse economic changes, including widespread liquidity issues and defaults in one or more industries; changes in interest, inflation or exchange rates; unexpected natural and man-made world events, such as diseases or disasters; financial, political or social disruptions, including terrorism and war; and U.S. trade disputes or other disputes with specific countries that could result in additional tariffs, trade barriers and/or investment restrictions in certain securities in those countries. Any of these conditions can adversely affect the economic prospects of many companies, sectors, nations, regions and the market in general, in ways that cannot necessarily be foreseen.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Calculation Methodology: The Index Provider relies on various sources of information to assess the criteria of issuers included in the Underlying Index (or the Parent Index), including information that may be based on assumptions and estimates. Neither the Fund nor the investment manager can offer assurances that the Underlying Index's calculation methodology or sources of information will

provide an accurate assessment of included issuers or that the included issuers will provide the Fund with the market exposure it seeks.

Non-Correlation: There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment goal. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. In addition, the Fund’s NAV may deviate from the Underlying Index if the Fund fair values a portfolio security at a price other than the price used by the Underlying Index for that security. To the extent that the investment manager uses a representative sampling strategy, the Fund may not track the return of the Underlying Index as well as it would have if the Fund held all of the securities in the Underlying Index.

Market Trading: The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than NAV when you buy shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those shares in the secondary

market. The investment manager cannot predict whether shares will trade above (premium), below (discount) or at NAV.

Information technology companies: Companies in the information technology sector have historically been volatile due to the rapid pace of product change and development within the sector. For example, their products and services may not prove commercially successful or may become obsolete quickly. In addition, delays in or cancellation of the release of anticipated products or services may also affect the price of an information technology company’s stock. Information technology companies are subject to significant competitive pressures, such as new market entrants, aggressive pricing and tight profit margins. The activities of these companies may also be adversely affected by changes in government regulations, worldwide technological developments or investor perception of a company and/or its products or services. The stock prices of companies operating within this sector may be subject to abrupt or erratic movements.

Large Capitalization Companies: Large capitalization companies may fall out of favor with investors based on market and economic conditions. Large capitalization companies may underperform relative to small and mid capitalization companies because they may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Passive Investment: Unlike many investment companies, the Fund is not actively managed and the investment manager does not attempt to take defensive positions under any market conditions, including declining markets. Therefore, the investment manager would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming.

Small Fund: When the Fund's size is small, the Fund may experience low trading volume and wide bid-ask spreads. In addition, the Fund may face the risk of being delisted if the Fund does not meet certain conditions of the listing exchange.

Cybersecurity: Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager, authorized participants, or index providers (as applicable) and listing exchanges, and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming shares or receiving distributions. The investment manager has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund or the investment manager. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in an effort to prevent or mitigate future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the Fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the Fund, the investment manager, and their service providers are subject to the risk of cyber incidents occurring from time to time.
