A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund&#x2019;s performance. Because the Fund is newly organized, portfolio turnover information is not yet available.&lt;/span&gt;&lt;/div&gt;</rr:PortfolioTurnoverTextBlock>

The initial universe of companies is screened based on their average projected free cash flows and earnings (if available) over each of the next two fiscal years. A company&#x2019;s projected free cash flows and earnings are determined by the Index Provider. Companies for which information on their projected free cash flows or earnings is not available will remain in the Index universe.

The equity securities of the 100 companies with the highest free cash flow margin are included in the Index. Companies included in the Index are weighted by their price momentum score and a company&#x2019;s price momentum score is calculated on each of the reconstitution dates. Price momentum is a speed of price changes in a security and shows the rate of price change over time to determine the extent of a trend. The effect of the price momentum score is to seek to overweight companies with relative positive price momentum, while seeking to underweight companies with relative negative price momentum over a period of approximately the prior twelve months.  &lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt;text-align:justify"&gt;&lt;span style="-sec-ix-redline:true;color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;The weight of any individual company included in the Index is capped at 5%. Weight above the 5% limitation is redistributed among the other Index constituents in proportion to their weights. As of February 29, 2024, the companies included in the Index had a market capitalization of $530 billion to $3.4 billion. The Index is reconstituted and rebalanced quarterly as of the close of business on the third Friday of March and September based on data as of the first Friday of the applicable rebalance month.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-right:2.25pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%"&gt;The Fund&#x2019;s Investment Strategy&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:9pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;Under normal circumstances, the Fund will seek to invest at least 80% of the Fund&#x2019;s total assets (exclusive of collateral held from securities lending) in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts).

This may occur because of factors that affect securities markets generally or factors affecting specific industries, sectors or companies in which the Fund invests. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change.

For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. The Fund&#x2019;s investments in depositary receipts may include American, European and Global Depositary Receipts (&#x201c;ADRs,&#x201d; &#x201c;EDRs,&#x201d; and &#x201c;GDRs,&#x201d; respectively). ADRs are receipts that represent interests in foreign securities held on deposit by U.S. banks. EDRs and GDRs have the same qualities as ADRs, except that they may be traded in several international trading markets.  Unsponsored depositary receipts are organized independently and without the cooperation of the foreign issuer of the underlying securities and involve additional risks because U.S. reporting requirements do not apply. In addition, the issuing bank may deduct shareholder distribution, custody, foreign currency exchange, and other fees from the payment of dividends.&lt;/span&gt;</rr:RiskTextBlock>

As a result, the Fund&#x2019;s performance may be adversely affected if securities of mid-capitalization companies underperform securities of other capitalization ranges or the market as a whole. Securities of smaller companies trade in smaller volumes and are often more vulnerable to market volatility than securities of larger companies.</rr:RiskTextBlock>

As a result, there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case it may experience greater tracking error to its Index than it otherwise would at higher asset levels, or it could ultimately liquidate. The Fund&#x2019;s distributor does not maintain a secondary market in Fund shares.&lt;/span&gt;</rr:RiskTextBlock>

As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund&#x2019;s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund&#x2019;s performance.&lt;/span&gt;</rr:RiskTextBlock>

The Fund invests in securities included in the Index, regardless of their investment merits.</rr:RiskTextBlock>

For example, the Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities, especially when rebalancing the Fund&#x2019;s securities holdings to reflect changes in the composition of the Index.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:700;line-height:120%"&gt; &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%"&gt;In addition, when the Fund uses a representative sampling approach, the Fund may not be as well correlated with the return of the Index as when the Fund purchases all of the securities in the Index in the proportions in which they are represented in the Index.&lt;/span&gt;</rr:RiskTextBlock>
