Strategy. The Fund uses a passive or indexing approach to try to achieve the Funds investment objective. Unlike many investment companies, the Fund does not try to beat the Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally expects to use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Index in approximately the same proportions as in the Index.

Unlike many investment companies, the Fund does not try to beat the Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally expects to use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Index in approximately the same proportions as in the Index. However, the Fund may utilize a representative sampling strategy with respect to the Index when a replication strategy might be detrimental to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to follow the Index, in instances in which a security in the Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Index. The Index tracks the performance of the exchange-listed equity securities (or corresponding American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs)) of companies across the globe that (i) engage in providing payment processing services or applications, (ii) provide payment solutions, (iii) build or provide payment industry architecture, infrastructure or software, or (iv) provide services as a credit card network (collectively, Mobile Payment Companies). Mobile Payment Companies are identified by Prime Indexes (the Index Provider), an independent index provider that is not affiliated with the Funds investment adviser. The Index Provider utilizes issuer financial statements and other public filings and reports, as well as third-party industry research, reports, and analyses, to identify Mobile Payment Companies around the world that meet the Indexs criteria for inclusion. Mobile Payment Companies are then screened for investibility ( e.g. , must not be listed on an exchange in a country which employs certain restrictions on foreign capital investment), a minimum market capitalization of $500 million for new component companies and $100 million for existing component companies, and an operating company structure (as opposed to a pass-through security). The Index Provider may exclude companies that meet the criteria for inclusion in the Index or include companies that do not meet such criteria if it determines that including or excluding them would be contrary to the objective of the Index ( e.g. , their inclusion would negatively affect the investibility of the Index, the companys economic fortunes are predominantly driven by a business not related to that of a Mobile Payments Company, the company is expected to meet the inclusion criteria in the immediate future and plays an important role in the mobile payments industry). The Index has a quarterly review in March, June, September, and December of each year at which times the Index is reconstituted and rebalanced by the Index Provider. The composition of the Index and the constituent weights are determined on the two Thursdays before the second Friday of each March, June, September, and December (or the next business day if this is a non-business day) (the Selection Day). Component changes are made after the market close on the third Friday of March, June, September, and December (or the next business day if the third Friday is not a business day) and become effective at the market opening on the next trading day. The Index is developed and owned by the Index Provider, and the Index is calculated and maintained by Solactive AG. The Index Provider is independent of Solactive AG, the Fund, and the Funds investment adviser. The Index constituents are weighted according to a modified market capitalization weighting methodology. Constituent weightings are modified in that each constituent weighting is capped at 6% of the Index and the cumulative weight of all constituents with an individual weight of 5% or greater may not in the aggregate account for more than 50% of the weight of the Index as of the Selection Day. In addition, constituents with a market capitalization of less than US $1 billion as of the Selection Day will have their weight reduced by 5585% depending on their specific market capitalization. The weight of any individual Index constituent whose weight is reduced due to the above-described limits will be redistributed equally among all other Index constituents whose weights are not in excess of such limits. As of January 10, 2023, the Index had 51 constituents. The Fund invests at least 80% of its total assets, exclusive of collateral held from securities lending, in the component securities of the Index and in ADRs and GDRs based on the component securities in the Index. The Fund may invest up to 20% of its total assets in securities that are not in the Funds Index to the extent that the Funds adviser believes such investments should help the Funds overall portfolio track the Index. The Fund may lend its portfolio securities to brokers, dealers, and other financial organizations. These loans, if and when made, may not exceed 33 1/3% of the total asset value of the Fund (including the loan collateral). By lending its securities, the Fund may increase its income by receiving payments from the borrower. The Fund rebalances its portfolio in accordance with its Index, and, therefore, any changes to the Indexs rebalance schedule will result in corresponding changes to the Funds rebalance schedule. Correlation: Correlation is the extent to which the values of different types of investments move in tandem with one another in response to changing economic and market conditions. An index is a theoretical financial calculation, while the Fund is an actual investment portfolio. The performance of the Fund and the Index may vary somewhat due to transaction costs, asset valuations, foreign currency valuations, market impact, corporate actions (such as mergers and spin-offs), legal restrictions or limitations, illiquid or unavailable securities, and timing variances. The Funds investment adviser expects that, over time, the correlation between the Funds performance and that of the Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Index than if it uses a representative sampling strategy. Industry Concentration: The Fund will concentrate its investments ( i.e ., hold 25% or more of its net assets) in a particular industry or group of related industries to approximately the same extent that the Index is concentrated. As of January 10, 2023, the Index was concentrated in companies in the information technology services industry. Show less
