Strictly in accordance with its guidelines and mandated procedures, S&P Dow Jones Indices LLC (S&P DJI or the Index Provider) compiles, maintains and calculates the Underlying Index, which is composed of a subset of securities from the S&P MidCap 400 Index that the Index Provider has determined to have high qualitythat is, stocks of companies that seek to generate higher revenue and cash flow than their counterparts through prudent use of assets and finances. The Index Provider assesses a securitys quality based on the following three fundamental measures: return on equity, accruals ratio and financial leverage ratio. Return on equity is calculated as the companys trailing 12-month earnings per share divided by the companys latest book value per share. Accruals ratio is computed using the change of the companys net operating assets over the last fiscal year divided by the companys average total assets over the last two fiscal years. Financial leverage is calculated as the companys latest total debt divided by the companys book value. The Index Provider assesses the quality of securities of companies in the financials or real estate sectors (according to the Global Industry Classification Standard (GICS )) based only on the return on equity and financial leverage ratio measures. In selecting constituent securities for the Underlying Index, the Index Provider calculates the quality score of each security in the S&P MidCap 400 Index and then selects the 80 stocks with the highest quality score for inclusion in the Underlying Index. The Index Provider weights each component stock of the Underlying Index by the product of its quality score multiplied by its market capitalization in the eligible universe, subject to security and sector constraints and optimization procedures. Stocks with higher scores receive relatively greater weights. As of June 30, 2025, the Underlying Index was comprised of 80 constituents with market capitalizations ranging from $1.7 billion to $23.9 billion. The Fund employs a full replication methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. The Fund intends to be diversified, as defined in the Investment Company Act of 1940, as amended (the 1940 Act), to the extent that the Underlying Index is diversified. The Fund may become non-diversified as defined in the 1940 Act solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Underlying Index. Should the Fund become non-diversified, it will no longer be required to meet certain diversification requirements under the 1940 Act and may invest a greater portion of its assets in securities of a small group of issuers or in any one individual issuer than can a diversified fund. Shareholder approval will not be sought when the Fund crosses from diversified to non-diversified status solely due to a change in relative market capitalization or index weighting of one or more constituents of the Underlying Index. In seeking to track the Underlying Index, the Fund was managed as diversified as of April 30, 2025. Concentration Policy. The Fund will concentrate its investments (i.e., invest 25% or more of the value of its total assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of April 30, 2025, the Fund had significant exposure to the industrials sector. The Funds portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time. Show less
