Additional Information About Investment Objectives, Policies, and Related Risks

The Fund’s investment objective and principal investment strategies are described in the Prospectus. The following information supplements, and should be read in conjunction with, the Prospectus. For a description of certain permitted investments, see “ Description of Permitted Investments ” in this SAI.

With respect to the Fund’s investments, unless otherwise noted, if a percentage limitation on investment is adhered to at the time of investment or contract, a subsequent increase or decrease as a result of market movement or redemption will not result in a violation of such investment limitation.

Non-Diversification

The Fund is classified as a non-diversified investment company under the 1940 Act. A “non-diversified” classification means that the Fund is not limited by the 1940 Act with regard to the percentage of its total assets that may be invested in the securities of a single issuer. This means that the Fund may invest a greater portion of its total assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund. The securities of a particular issuer may constitute a greater portion of the Index and, therefore, those securities may constitute a greater portion of the Fund’s portfolio. This may have an adverse effect on the Fund’s performance or subject Shares to greater price volatility than more diversified investment companies. Moreover, in pursuing its objective, the Fund may hold the securities of a single issuer in an amount exceeding 10% of the value of the outstanding securities of the issuer, subject to restrictions with respect to the Fund’s intention to qualify as a regulated investment company (“RIC”) imposed by the Internal Revenue Code of 1986, as amended (the “Code”). In particular, as the Fund’s size grows and its assets increase, it will be more likely to hold more than 10% of the securities of a single issuer if the issuer has a relatively small public float as compared to other components in the Index.

Although the Fund is non-diversified for purposes of the 1940 Act, the Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a RIC for purposes of the Code. Compliance with the diversification requirements of the Code may severely limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objectives. To qualify as a RIC under the Code, the Fund must, among other requirements described below in “Federal Income Taxes”, meet certain diversification requirements. In particular, at the close of each quarter of the Fund’s taxable year: (A) at least 50% of the value of its total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater than 5% of the value of the Fund’s total assets and that does not represent more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (B) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer or the securities (other than the securities of another RIC) of two or more issuers that the Fund controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly traded partnerships. See “Federal Income Taxes” in this SAI for further discussion.

General Risks

The value of the Fund’s portfolio securities may fluctuate with changes in the financial condition of an issuer or counterparty, changes in specific economic or political conditions that affect a particular security or issuer and changes in general economic or political conditions. An investor in the Fund could lose money over short or long periods of time.

There can be no guarantee that a liquid market for such securities will be maintained. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of Shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Financial markets, both domestic and foreign, have experienced an unusually high degree of volatility as recently as the beginning of 2018. Continuing market turbulence may have an adverse effect on Fund performance.

Cyber Security Risk . Investment companies, such as the Fund, and their service providers may be subject to operational and information security risks resulting from cyber attacks. Cyber attacks include, among other behaviors, stealing or corrupting data maintained online or digitally, denial of service attacks on websites, the unauthorized release of confidential information or various other forms of cyber security breaches. Cyber attacks affecting the Fund or the Adviser, Sub-Adviser, custodian, transfer agent, intermediaries and other third-party service providers may adversely impact the Fund. For instance, cyber attacks may interfere with the processing of shareholder transactions, impact the Fund’s ability to calculate its NAV, cause the release of private shareholder information or confidential company information, impede trading, subject the Fund to regulatory fines or financial losses, and cause reputational damage. The Fund may also incur additional costs for cyber security risk management purposes. Similar types of cyber security risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund’s investments in such portfolio companies to lose value.

Index Calculation

To minimize any potential for conflicts caused by the fact that the Fund’s Adviser acts as index provider to the Fund, the index provider has retained an unaffiliated third party to calculate the Index (the “Calculation Agent”). The Calculation Agent, using the rules-based methodology, will calculate, maintain, and disseminate the Index on a quarterly basis. The Adviser will monitor the results produced by the Calculation Agent to help ensure that the Index is being calculated in accordance with the rules-based methodology. In addition, the index provider has established policies and procedures designed to prevent improper use and dissemination of non-public information about the Fund’s portfolio strategies and pending changes to the Index.

Description of Permitted Investments

The following are descriptions of the permitted investments and investment practices and the associated risk factors. The Fund will only invest in any of the following instruments or engage in any of the following investment practices if such investment or activity is consistent with the Fund’s investment objective and permitted by the Fund’s stated investment policies.

Borrowing . Although the Fund does not intend to borrow money, the Fund may do so to the extent permitted by the 1940 Act. Under the 1940 Act, the Fund may borrow up to one-third (1/3) of its total assets. The Fund will borrow money only for short-term or emergency purposes. Such borrowing is not for investment purposes and will be repaid by the Fund promptly. Borrowing will tend to exaggerate the effect on NAV of any increase or decrease in the market value of the Fund’s portfolio. Money borrowed will be subject to interest costs that may or may not be recovered by earnings on the securities purchased. The Fund also may be required to maintain minimum average balances in connection with a borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

Equity Securities. Equity securities, such as the common stocks of an issuer, are subject to stock market fluctuations and therefore may experience volatile changes in value as market conditions, consumer sentiment or the financial condition of the issuers change. A decrease in value of the equity securities in the Fund’s portfolio may also cause the value of Shares to decline.

An investment in the Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of the Fund’s portfolio securities and therefore a decrease in the value of Shares). Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence and perceptions change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic or banking crises.

Holders of common stocks incur more risk than holders of preferred stocks and debt obligations because common stockholders, as owners of the issuer, generally have inferior rights to receive payments from the issuer in comparison with the rights of creditors or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (whose value, however, is subject to market fluctuations prior thereto), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity. Common stock values are subject to market fluctuations as long as the common stock remains outstanding.

When-Issued Securities – A when-issued security is one whose terms are available and for which a market exists, but which has not been issued. When the Fund engages in when-issued transactions, it relies on the other party to consummate the sale. If the other party fails to complete the sale, the Fund may miss the opportunity to obtain the security at a favorable price or yield.

When purchasing a security on a when-issued basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield changes. At the time of settlement, the value of the security may be more or less than the purchase price. The yield available in the market when the delivery takes place also may be higher than those obtained in the transaction itself. Because the Fund does not pay for the security until the delivery date, these risks are in addition to the risks associated with its other investments.

Decisions to enter into “when-issued” transactions will be considered on a case-by-case basis when necessary to maintain continuity in a company’s index membership. The Fund will segregate cash or liquid securities equal in value to commitments for the when-issued transactions. The Fund will segregate additional liquid assets daily so that the value of such assets is equal to the amount of the commitments.

Types of Equity Securities:

Common Stocks — Common stocks represent units of ownership in a company. Common stocks usually carry voting rights and earn dividends. Unlike preferred stocks, which are described below, dividends on common stocks are not fixed but are declared at the discretion of the company’s board of directors.

Preferred Stocks — Preferred stocks are also units of ownership in a company. Preferred stocks normally have preference over common stock in the payment of dividends and the liquidation of the company. However, in all other respects, preferred stocks are subordinated to the liabilities of the issuer. Unlike common stocks, preferred stocks are generally not entitled to vote on corporate matters. Types of preferred stocks include adjustable-rate preferred stock, fixed dividend preferred stock, perpetual preferred stock, and sinking fund preferred stock.

Generally, the market values of preferred stock with a fixed dividend rate and no conversion element vary inversely with interest rates and perceived credit risk.

Rights and Warrants — A right is a privilege granted to existing shareholders of a corporation to subscribe to shares of a new issue of common stock before it is issued. Rights normally have a short life of usually two to four weeks, are freely transferable and entitle the holder to buy the new common stock at a lower price than the public offering price. Warrants are securities that are usually issued together with a debt security or preferred stock and that give the holder the right to buy proportionate amount of common stock at a specified price. Warrants are freely transferable and are traded on major exchanges. Unlike rights, warrants normally have a life that is measured in years and entitles the holder to buy common stock of a company at a price that is usually higher than the market price at the time the warrant is issued. Corporations often issue warrants to make the accompanying debt security more attractive.

An investment in warrants and rights may entail greater risks than certain other types of investments. Generally, rights and warrants do not carry the right to receive dividends or exercise voting rights with respect to the underlying securities, and they do not represent any rights in the assets of the issuer. In addition, their value does not necessarily change with the value of the underlying securities, and they cease to have value if they are not exercised on or before their expiration date. Investing in rights and warrants increases the potential profit or loss to be realized from the investment as compared with investing the same amount in the underlying securities.

Real Estate Investment Trusts (“REITs”) — A REIT is a corporation or business trust (that would otherwise be taxed as a corporation) which meets the definitional requirements of the Code. The Code permits a qualifying REIT to deduct from taxable income the dividends paid, thereby effectively eliminating corporate level federal income tax. To meet the definitional requirements of the Code, a REIT must, among other things: invest substantially all of its assets in interests in real estate (including mortgages and other REITs), cash and government securities; derive most of its income from rents from real property or interest on loans secured by mortgages on real property; and, in general, distribute annually 90% or more of its taxable income (other than net capital gains) to shareholders.

REITs are sometimes informally characterized as Equity REITs and Mortgage REITs. An Equity REIT invests primarily in the fee ownership or leasehold ownership of land and buildings (e.g., commercial equity REITs and residential equity REITs); a Mortgage REIT invests primarily in mortgages on real property, which may secure construction, development or long-term loans.

REITs may be affected by changes in underlying real estate values, which may have an exaggerated effect to the extent that REITs in which the Fund invests may concentrate investments in particular geographic regions or property types. Additionally, rising interest rates may cause investors in REITs to demand a higher annual yield from future distributions, which may in turn decrease market prices for equity securities issued by REITs. Rising interest rates also generally increase the costs of obtaining financing, which could cause the value of the Fund’s investments to decline. During periods of declining interest rates, certain Mortgage REITs may hold mortgages that the mortgagors elect to prepay, which prepayment may diminish the yield on securities issued by such Mortgage REITs. In addition, Mortgage REITs may be affected by the ability of borrowers to repay when due the debt extended by the REIT and Equity REITs may be affected by the ability of tenants to pay rent.

Certain REITs have relatively small market capitalization, which may tend to increase the volatility of the market price of securities issued by such REITs. Furthermore, REITs are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. By investing in REITs indirectly through the Fund, a shareholder will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, similar expenses of the REITs. REITs depend generally on their ability to generate cash flow to make distributions to shareholders.

In addition to these risks, Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while Mortgage REITs may be affected by the quality of any credit extended. Further, Equity and Mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and Mortgage REITs are also subject to heavy cash flow dependency defaults by borrowers and self-liquidation. In addition, Equity and Mortgage REITs could possibly fail to qualify for the favorable U.S. federal income tax treatment generally available to REITs under the Code or fail to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments.

Smaller Companies — The securities of small- and mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small- and mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small- or mid-capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning small- and mid-capitalization companies than for larger, more established companies. Small- and mid-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs, and earnings.

Tracking Stocks — The Fund may invest in tracking stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and which is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

Exchange-Traded Funds. The Fund may invest in shares of other investment companies (including exchange-traded funds (“ETFs”)). As the shareholder of another ETF, the Fund would bear, along with other shareholders, its pro rata portion of the other ETF’s expenses, including advisory fees. Such expenses are in addition to the expenses the Fund pays in connection with its own operations. The Fund’s investments in other ETFs may be limited by applicable law.

Disruptions in the markets for the securities underlying ETFs purchased or sold by the Fund could result in losses on investments in ETFs. ETFs also carry the risk that the price the Fund pays or receives may be higher or lower than the ETF’s NAV. ETFs are also subject to certain additional risks, including the risks of illiquidity and of possible trading halts due to market conditions or other reasons, based on the policies of the relevant exchange. ETFs and other investment companies in which the Fund may invest may be leveraged, which would increase the volatility of the Fund’s NAV.

Fixed-Income Securities .   The Fund may invest directly or indirectly in fixed-income securities. Even though interest-bearing securities are investments that promise a stable stream of income, the prices of such securities are affected by changes in interest rates. In general, fixed-income security prices rise when interest rates fall and fall when interest rates rise. Securities with shorter maturities, while offering lower yields, generally provide greater price stability than longer term securities and are less affected by changes in interest rates. The values of fixed-income securities also may be affected by changes in the credit rating or financial condition of the issuing entities. Once the rating of a portfolio security has been changed, the Fund will consider all circumstances deemed relevant in determining whether to continue to hold the security.

Fixed income investments bear certain risks, including credit risk, or the ability of an issuer to pay interest and principal as they become due. Generally, higher yielding bonds are subject to more credit risk than lower yielding bonds. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between the market value of outstanding fixed-income securities and changes in interest rates. An increase in interest rates will generally reduce the market value of fixed income investments and a decline in interest rates will tend to increase their value.

A number of factors, including changes in a central bank’s monetary policies or general improvements in the economy, may cause interest rates to rise. Fixed-income securities with longer durations are more sensitive to interest rate changes than securities with shorter durations, making them more volatile. This means their prices are more likely to experience a considerable reduction in response to a rise in interest rates.

Fixed-Income Securities Ratings .   The nationally recognized statistical rating organizations (“NRSROs”) publish ratings based upon their assessment of the relative creditworthiness of the rated fixed-income securities. Generally, a lower rating indicates higher credit risk, and higher yields are ordinarily available from fixed-income securities in the lower rating categories to compensate investors for the increased credit risk. Any use of credit ratings in evaluating fixed-income securities can involve certain risks. For example, ratings assigned by the rating agencies are based upon an analysis completed at the time of the rating of the obligor’s ability to pay interest and repay principal, typically relying to a large extent on historical data. Rating agencies typically rely to a large extent on historical data which may not accurately represent present or future circumstances. Ratings do not purport to reflect to risk of fluctuations in market value of the fixed-income security and are not absolute standards of quality and only express the rating agency’s current opinion of an obligor’s overall financial capacity to pay its financial obligations. A credit rating is not a statement of fact or a recommendation to purchase, sell or hold a fixed-income obligation. Also, credit quality can change suddenly and unexpectedly, and credit ratings may not reflect the issuer’s current financial condition or events since the security was last rated. Rating agencies may have a financial interest in generating business, including the arranger or issuer of the security that normally pays for that rating, and a low rating might affect future business. While rating agencies have policies and procedures to address this potential conflict of interest, there is a risk that these policies will fail to prevent a conflict of interest from impacting the rating. Additionally, legislation has been enacted in an effort to reform rating agencies. Rules have also been adopted by the SEC to require rating agencies to provide additional disclosure and reduce conflicts of interest, and further reform has been proposed. It is uncertain how such legislation or additional regulation might impact the ratings agencies business and the Sub-Adviser’s investment process.

Illiquid Investments. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid investments, as such term is defined by Rule 22e-4 of the 1940 Act. A Fund may not invest in illiquid investments if, as a result of such investment, more than 15% of the Fund’s net assets would be invested in illiquid investments. Illiquid investments include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets. The inability of the Fund to dispose of illiquid investments readily or at a reasonable price could impair the Fund’s ability to raise cash for redemptions or other purposes. The liquidity of securities purchased by the Fund that are eligible for resale pursuant to Rule 144A, except for certain 144A bonds, will be monitored by the Fund on an ongoing basis. In the event more than 15% of a Fund’s net assets are invested in illiquid investments, the Fund, in accordance with Rule 22e-4(b)(1)(iv), will report the occurrence to both the Board and the SEC and seek to reduce its holdings of illiquid investments within a reasonable period of time.

Investment Company Securities. The Fund may invest in the securities of other investment companies, including money market funds and exchange-traded funds, subject to applicable limitations under Section 12(d)(1) of the 1940 Act. Investing in another pooled vehicle exposes the Fund to all the risks of that pooled vehicle. Pursuant to Section 12(d)(1), the Fund may invest in the securities of another investment company (the “acquired company”) provided that the Fund, immediately after such purchase or acquisition, does not own in the aggregate: (i) more than 3% of the total outstanding voting stock of the acquired company; (ii) securities issued by the acquired company having an aggregate value in excess of 5% of the value of the total assets of the Fund; or (iii) securities issued by the acquired company and all other investment companies (other than treasury stock of the Fund) having an aggregate value in excess of 10% of the value of the total assets of the Fund. To the extent allowed by law or regulation, the Fund may invest its assets in securities of investment companies that are money market funds in excess of the limits discussed above.

If the Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in securities of other registered investment companies, including the Fund. The acquisition of Shares by registered investment companies is subject to the restrictions of Section 12(d)(1) of the 1940 Act, except as may be permitted by exemptive rules under the 1940 Act or as may at some future time be permitted by an exemptive order that permits registered investment companies to invest in the Fund beyond the limits of Section 12(d)(1), subject to certain terms and conditions, including that the registered investment company enter into an agreement with the Fund regarding the terms of the investment.

The Fund may rely on Section 12(d)(1)(F) and Rule 12d1-3 of the 1940 Act, which provide an exemption from Section 12(d)(1) that allows the Fund to invest all of its assets in other registered funds, including ETFs, if, among other conditions: (a) the Fund, together with its affiliates, acquires no more than three percent of the outstanding voting stock of any acquired fund, and (b) the sales load charged on Shares is no greater than the limits set forth in Rule 2830 of the Conduct Rules of the Financial Industry Regulatory Authority, Inc. (“FINRA”). Additionally, the Fund may rely on exemptive relief issued by the SEC to other registered funds, including ETFs, to invest in such other funds in excess of the limits of Section 12(d)(1) if the Fund complies with the terms and conditions of such exemptive relief.

Money Market Instruments. The Fund may invest a portion of its assets in high-quality money market instruments on an ongoing basis to provide liquidity or for other reasons. The instruments in which the Fund may invest include: (i) short-term obligations issued by the U.S. Government; (ii) negotiable certificates of deposit (“CDs”), fixed time deposits and bankers’ acceptances of U.S. and foreign banks and similar institutions; (iii) commercial paper rated at the date of purchase “Prime-1” by Moody’s or “A-1+” or “A-1” by Standard & Poor’s (“S&P”) or, if unrated, of comparable quality as determined by the Fund; and (iv) repurchase agreements. CDs are short-term negotiable obligations of commercial banks. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Banker’s acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Portfolio Turnover. The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

Repurchase Agreements. The Fund may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. A repurchase agreement is a transaction in which the Fund purchases securities or other obligations from a bank or securities dealer (or its affiliate) and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. The Fund maintains custody of the underlying obligations prior to their repurchase, either through its regular custodian or through a special “tri-party” custodian or sub-custodian that maintains separate accounts for both the Fund and its counterparty. Thus, the obligation of the counterparty to pay the repurchase price on the date agreed to or upon demand is, in effect, secured by such obligations.

Repurchase agreements carry certain risks not associated with direct investments in securities, including a possible decline in the market value of the underlying obligations. If their value becomes less than the repurchase price, plus any agreed-upon additional amount, the counterparty must provide additional collateral so that at all times the collateral is at least equal to the repurchase price plus any agreed-upon additional amount. The difference between the total amount to be received upon repurchase of the obligations and the price that was paid by the Fund upon acquisition is accrued as interest and included in its net investment income. Repurchase agreements involving obligations other than U.S. Government securities (such as commercial paper and corporate bonds) may be subject to special risks and may not have the benefit of certain protections in the event of the counterparty’s insolvency. If the seller or guarantor becomes insolvent, the Fund may suffer delays, costs and possible losses in connection with the disposition of collateral.

Other Short-Term Instruments . In addition to repurchase agreements, the Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds; (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed time deposits and other obligations of U.S. and foreign banks (including foreign branches) and similar institutions; (iv) commercial paper rated at the date of purchase “Prime-1” by Moody’s or “A-1” by S&P or, if unrated, of comparable quality as determined by the Sub-Adviser; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; and (vi) short-term U.S. dollar-denominated obligations of foreign banks (including U.S. branches) that, in the opinion of the Sub-Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by the Fund. Any of these instruments may be purchased on a current or a forward-settled basis. Money market instruments also include shares of money market funds. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Securities Lending. The Fund may lend portfolio securities to certain creditworthy borrowers, including the Fund’s securities lending agent. Loans of portfolio securities provide the Fund with the opportunity to earn additional income on the Fund’s portfolio securities. All securities loans will be made pursuant to agreements requiring the loans to be continuously secured by collateral in cash, or money market instruments, or money market funds at least equal at all times to the market value of the loaned securities. The borrower pays to the Fund an amount equal to any dividends or interest received on loaned securities. The Fund retains all or a portion of the interest received on investment of cash collateral or receives a fee from the borrower. Lending portfolio securities involves risks of delay in recovery of the loaned securities or in some cases loss of rights in the collateral should the borrower fail financially. Furthermore, because of the risks of delay in recovery, the Fund may lose the opportunity to sell the securities at a desirable price. The Fund will generally not have the right to vote securities while they are being loaned.

Short Sales. The Fund engages in short sales. Short sales are transactions in which the Fund sells an instrument it does not own in anticipation of a decline in the market value of that instrument. To complete a short sale transaction, the Fund must borrow the instrument to make delivery to the buyer. The Fund then is obligated to replace the instrument borrowed by purchasing it at the market price at the time of replacement. The price at such time may be more or less than the price at which the instrument was sold by the Fund. Until the instrument is replaced, the Fund is required to pay to the lender amounts equal to any interest or dividends which accrue during the period of the loan. To borrow the instrument, the Fund also may be required to pay a premium, which would increase the cost of the instrument sold. There will also be other costs associated with short sales.

The Fund will incur a loss as a result of the short sale if the price of the instrument increases between the date of the short sale and the date on which the Fund replaces the borrowed instrument. Unlike taking a long position in an instrument by purchasing the instrument, where potential losses are limited to the purchase price, short sales have no cap on maximum loss. The Fund will realize a gain if the instrument declines in price between those dates. This result is the opposite of what one would expect from a cash purchase of a long position in an instrument.

Until the Fund replaces a borrowed instrument in connection with a short sale, the Fund will (a) designate on its records as collateral cash or liquid assets at such a level that the designated assets plus any amount deposited with the broker as collateral will equal the current value of the instrument sold short or (b) otherwise cover its short position in accordance with applicable law. The amount designated on the Fund’s records will be marked to market daily. This may limit the Fund’s investment flexibility, as well as its ability to meet redemption requests or other current obligations.

There is no guarantee that the Fund will be able to close out a short position at any particular time or at an acceptable price. During the time that the Fund is short an instrument, it is subject to the risk that the lender of the instrument will terminate the loan at a time when the Fund is unable to borrow the same instrument from another lender. If that occurs, the Fund may be “bought in” at the price required to purchase the instrument needed to close out the short position, which may be a disadvantageous price. Thus, there is a risk that the Fund may be unable to fully implement its investment strategy due to a lack of available instruments or for some other reason. It is possible that the market value of the instruments the Fund holds in long positions will decline at the same time that the market value of the instruments the Fund has sold short increases, thereby increasing the Fund’s potential volatility. Short sales also involve other costs. The Fund must normally repay to the lender an amount equal to any dividends or interest that accrues while the loan is outstanding. In addition, to borrow the instrument, the Fund may be required to pay a premium. The Fund also will incur transaction costs in effecting short sales. The amount of any ultimate gain for the Fund resulting from a short sale will be decreased, and the amount of any ultimate loss will be increased, by the amount of premiums, dividends, interest or expenses the Fund may be required to pay in connection with the short sale.

Tax Risks. As with any investment, you should consider how your investment in Shares will be taxed. The tax information in the Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares.

Unless your investment in Shares is made through a tax-exempt entity or tax-deferred retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Shares.

U.S. Government Securities. The Fund may invest in U.S. government securities. Securities issued or guaranteed by the U.S. government or its agencies or instrumentalities include U.S. Treasury securities, which are backed by the full faith and credit of the U.S. Treasury and which differ only in their interest rates, maturities, and times of issuance. U.S. Treasury bills have initial maturities of one-year or less; U.S. Treasury notes have initial maturities of one to ten years; and U.S. Treasury bonds generally have initial maturities of greater than ten years. Certain U.S. government securities are issued or guaranteed by agencies or instrumentalities of the U.S. government including, but not limited to, obligations of U.S. government agencies or instrumentalities such as the Federal National Mortgage Association (“Fannie Mae”), the Government National Mortgage Association (“Ginnie Mae”), the Small Business Administration, the Federal Farm Credit Administration, the Federal Home Loan Banks, Banks for Cooperatives (including the Central Bank for Cooperatives), the Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation (Farmer Mac).

Some obligations issued or guaranteed by U.S. government agencies and instrumentalities, including, for example, Ginnie Mae pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by Fannie Mae, are supported by the discretionary authority of the U.S. government to purchase certain obligations of the federal agency, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury, while the U.S. government provides financial support to such U.S. government-sponsored federal agencies, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law. U.S. Treasury notes and bonds typically pay coupon interest semi-annually and repay the principal at maturity.

On September 7, 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and the Federal Home Loan Mortgage Corporation (“Freddie Mac”), placing the two federal instrumentalities in conservatorship. Under the takeover, the U.S. Treasury agreed to acquire $1 billion of senior preferred stock of each instrumentality and obtained warrants for the purchase of common stock of each instrumentality (the “Senior Preferred Stock Purchase Agreement” or “Agreement”). Under the Agreement, the U.S. Treasury pledged to provide up to $200 billion per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their assets. This was intended to ensure that the instrumentalities maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. On December 24, 2009, the U.S. Treasury announced that it was amending the Agreement to allow the $200 billion cap on the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in net worth over the next three years. As a result of this Agreement, the investments of holders, including the Fund, of mortgage-backed securities and other obligations issued by Fannie Mae and Freddie Mac are protected.

The total public debt of the United States as a percentage of gross domestic product has grown rapidly since the beginning of the 2008–2009 financial downturn.  Although high debt levels do not necessarily indicate or cause economic problems, they may create certain systemic risks if sound debt management practices are not implemented.  A high national debt can raise concerns that the U.S. government will not be able to make principal or interest payments when they are due.  This increase has also necessitated the need for the U.S. Congress to negotiate adjustments to the statutory debt limit to increase the cap on the amount the U.S. government is permitted to borrow to meet its existing obligations and finance current budget deficits. In August 2011, S&P lowered its long term sovereign credit rating on the U.S. In explaining the downgrade at that time, S&P cited, among other reasons, controversy over raising the statutory debt ceiling and growth in public spending. On February 9, 2018, following passage by Congress, the President of the United States signed the Bipartisan Budget Act of 2018, which suspends the statutory debt limit through March 1, 2019. Congress has not yet acted to either extend the suspension or permanently raise the debt limit and, until it does, the U.S. government is implementing “extraordinary measures,” such as temporarily suspending payments to federal retirement funds.  Any controversy or ongoing uncertainty regarding the statutory debt ceiling negotiations may impact the U.S. long-term sovereign credit rating and may cause market uncertainty. As a result, market prices and yields of securities supported by the full faith and credit of the U.S. government may be adversely affected.

Investment Restrictions

The Trust has adopted the following investment restrictions as fundamental policies with respect to the Fund. These restrictions cannot be changed with respect to the Fund without the approval of the holders of a majority of the Fund’s outstanding voting securities. For the purposes of the 1940 Act, a “majority of outstanding shares” means the vote of the lesser of: (1) 67% or more of the voting securities of the Fund present at the meeting if the holders of more than 50% of the Fund’s outstanding voting securities are present or represented by proxy; or (2) more than 50% of the outstanding voting securities of the Fund.

Except with the approval of a majority of the outstanding voting securities, the Fund may not:

In addition to the investment restrictions adopted as fundamental policies as set forth above, the Fund observes the following non-fundamental restrictions, which may be changed without a shareholder vote.

If a percentage limitation is adhered to at the time of investment or contract, a later increase or decrease in percentage resulting from any change in value or total or net assets will not result in a violation of such restriction, except that the percentage limitations with respect to the borrowing of money will be observed continuously.

Exchange Listing and Trading

Shares are listed for trading and trade throughout the day on the Exchange.

There can be no assurance that the Fund will continue to meet the requirements of the Exchange necessary to maintain the listing of Shares. The Exchange will consider the suspension of trading in, and will initiate delisting proceedings of, Shares under any of the following circumstances: (i) if any of the requirements set forth in the Exchange rules are not continuously maintained; (ii) if the Exchange files separate proposals under Section 19(b) of the 1940 Act and any of the statements regarding (a) the index composition; (b) the description of the Fund; (c) limitations on the Fund’s portfolio holdings or reference assets; (d) dissemination and availability of the index or intraday indicative values; or (e) the applicability of the Exchange listing rules specified in such proposals are not continuously maintained; (iii) if following the initial 12-month period beginning at the commencement of trading of the Fund, there are fewer than 50 beneficial owners of Shares; (iv) if the value of the Fund’s underlying index is no longer calculated or available or an interruption to the dissemination persists past the trading day in which it occurred or the underlying index is replaced with a new index, unless the new underlying index meets certain Exchange requirements; (v) if the intraday indicative value is no longer disseminated at least every 15 seconds during the Exchange’s regular market session and the interruption to the dissemination persists past the trading day in which it occurred; or (vi) such other event shall occur or condition shall exist that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. The Exchange will remove Shares from listing and trading upon termination of the Fund.

The Trust reserves the right to adjust the price levels of Shares in the future to help maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

To provide additional information regarding the indicative value of Shares, the Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or other widely disseminated means, an updated “intraday indicative value” (“IIV”) for the Fund as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IIVs and makes no representation or warranty as to the accuracy of the IIVs.
