MainStay Cushing Energy Income Fund

and to the extent the Fund invests in MLP-related investments or other non-partnership entities, this could result in a reduction of the value of your investment in the Fund and lower income.

·   The portion, if any, of a distribution received by the Fund as the holder of an MLP equity security that is offset by the MLP’s tax deductions or losses generally will be treated as a return of capital to the extent of the Fund’s tax basis in the MLP equity security, which will cause income or gain to be higher, or losses to be lower, upon the sale of the MLP security by the Fund. The actual portion of the distributions received by the Fund that are considered return of capital will not be known until the Fund receives a Form 1065, Schedule K-1 with respect to each of its MLP investments. Distributions received by shareholders from the Fund that are treated as return of capital would not be subject to U.S. federal income tax, but would have the effect of reducing a shareholder’s basis in the shares of the Fund, which would cause gains to be higher, or losses to be lower, upon the sale of shares by such shareholder.

·   The Fund has elected to be treated as a regulated investment company under the Internal Revenue Code. Because more than 25% of the Fund’s total assets had been comprised of securities of MLPs that were qualified publicly traded partnerships under the Internal Revenue Code, the Fund was previously ineligible to elect to be treated as a regulated investment company. Accordingly, the Fund was subject to tax on its taxable income at the graduated rates applicable to corporations as well as state, local and foreign income taxes.

·   Under recent tax legislation, individuals and certain other noncorporate entities are generally eligible for a 20% deduction with respect to taxable income from MLPs. The Fund will not be eligible for the 20% deduction and will not pass through the 20% deduction to shareholders. As a result, in comparison, investors investing directly in MLPs generally would be eligible for the 20% deduction for such taxable income from these investments while investors investing in MLPs held indirectly, if any, through the Fund would not be eligible for the 20% deduction for their share of such taxable income.

·   Changes in tax laws, regulations or interpretations of those laws or regulations in the future could adversely affect the Fund or the Energy Companies in which the Fund will invest.

Equity Securities Risk: Equity securities of Energy Companies may be affected by macroeconomic, political, global and other factors affecting the stock market in general, expectations concerning interest rate movements, investor sentiment towards the energy sector, changes in a particular issuer’s financial condition, or unfavorable or unanticipated poor performance of a particular Energy Company (which, in the case of an MLP, may be measured in terms of distributable cash flow or other factors). Prices of equity securities of individual Energy Companies can also be affected by fundamentals unique to the company, including earnings power and coverage ratios.

Common Stock Risk: The Fund will have exposure to common stocks. Although common stocks have historically generated higher average total returns than fixed-income securities over the long-term, common stocks also have experienced significantly more volatility in those returns and may significantly underperform relative to fixed-income securities during certain periods. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock held by the Fund. Also, the price of common stocks is sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks to which the Fund has exposure. Common stock prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuers occur. In addition, common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase.

Market Capitalization Risk: To the extent the Fund invests in securities issued by small-, mid-, or large-cap companies, the Fund will be subject to the risks associated with securities issued by companies of the applicable market capitalization.  Securities of small-cap and mid-cap companies may be subject to greater price volatility, significantly lower trading volumes, cyclical, static or moderate growth prospects and greater spreads between their bid and ask prices than securities of larger companies. Smaller capitalization companies frequently rely on narrower product lines and niche markets and may be more vulnerable to adverse business or market developments.  Securities issued by larger companies may have less growth potential and may not be able to attain the high growth rates of successful smaller companies, especially during strong economic periods.  In addition, larger companies may be less capable of responding quickly to competitive challenges and industry changes, including those resulting from improvements in technology, and may suffer sharper price declines as a result of earnings disappointments.  There is a risk that the securities issued by companies of a certain market capitalization may underperform the broader market at any given time.

Debt Securities Risk: The risks of investing in debt or fixed-income securities include (without limitation): (i) credit risk, e.g., the issuer or guarantor of a debt security may be unable or unwilling (or be perceived as unable or unwilling) to make timely principal and/or interest payments or otherwise honor its obligations; (ii) maturity risk, e.g., a debt security with a longer maturity may fluctuate in value more than one with a shorter maturity; (iii) market risk, e.g., low demand for debt securities may negatively impact their price; (iv) interest rate risk, e.g., when interest rates go up, the value of a debt security generally goes down, and when interest rates go down, the value of a debt security generally goes up (long-term debt securities are generally more susceptible to interest rate risk than short-term debt securities); and (v) call risk, e.g., during a period of falling interest rates, the issuer may redeem a security by repaying it early, which may reduce the Fund’s income if the proceeds are reinvested at lower interest rates.

Interest rates in the United States are near historic lows, and the Fund currently faces a heightened level of interest rate risk. To the extent the Board of Governors of the Federal Reserve System (“Federal Reserve Board”) continues to raise the federal funds rate, there is a risk that interest rates across the financial system may rise, possibly significantly and/or rapidly . Rising interest rates or lack of market participants may lead to decreased liquidity and increased volatility in the fixed-income or debt markets, making it more difficult for the Fund to sell its fixed-income or debt

Industry Specific Risk: MLPs and other natural resources sector companies are also subject to risks that are specific to the particular industry in which they operate.

MLP Structure Risk: Holders of MLP units are subject to certain risks inherent in the structure of MLPs, including (i) tax risks; (ii) the limited ability to elect or remove management or the general partner or managing member; (iii) limited voting rights, except with respect to extraordinary transactions; and (iv) conflicts of interest between the general partner or managing member and its affiliates, on the one hand, and the limited partners or members, on the other hand, including those arising from incentive distribution payments or corporate opportunities.

Tax Risks: An investment in the Fund will involve tax risks, including, but not limited to:

·   MLPs generally are not subject to U.S. federal income tax at the partnership level. Rather, each partner is allocated a share of the partnership’s income, gains, losses, credits, deductions and expenses. A change in current tax law, or a change in the underlying business mix of a given MLP, could result in an MLP being treated as a corporation for U.S. federal income tax purposes, which would result in such MLP being subject to U.S. federal income tax on its taxable income as well as additional state and local taxes. The treatment of an MLP as a corporation for U.S. federal income tax purposes would, among other consequences, have the effect of reducing the amount of cash available for distribution by the MLP. Thus, to the extent the MLPs owned by the Fund are treated as corporations for U.S. federal income tax purposes and to the extent the Fund invests in MLP-related investments or other non-partnership entities, this could result in a reduction of the value of your investment in the Fund and lower income.

·   The portion, if any, of a distribution received by the Fund as the holder of an MLP equity security that is offset by the MLP’s tax deductions or losses generally will be treated as a return of capital to the extent of the Fund’s tax basis in the MLP equity security, which will cause income or gain to be higher, or losses to be lower, upon the sale of the MLP security by the Fund. The actual portion of the distributions received by the Fund that are considered return of capital will not be known until the Fund receives a Form 1065, Schedule K-1 with respect to each of its MLP investments. Distributions received by shareholders from the Fund that are treated as return of capital would not be subject to U.S. federal income tax, but would have the effect of reducing a shareholder’s basis in the shares of the Fund, which would cause gains to be higher, or losses to be lower, upon the sale of shares by such shareholder.

·   The Fund’s actual tax liability with respect to any taxable year will not be known until the Fund completes its annual tax returns for such taxable year. The Fund’s tax estimates used to compute its NAV could vary substantially from its actual tax liability and therefore the determination of the Fund’s actual tax liability may have a material impact on the Fund’s NAV. The payment of corporate income taxes imposed on the Fund will decrease cash available for distribution to shareholders.

·   As a “C” corporation, for U.S. federal income tax purposes, the Fund will account for its current and deferred income tax liability and/or asset balances when calculating its daily NAV in accordance with generally accepted accounting principles. The Fund will accrue a deferred income tax liability balance, at the currently effective statutory U.S. federal income tax rate (currently 21%) plus an estimated state and local income tax rate, for its future tax liability associated with the capital appreciation of its investments and the distributions received by the Fund on equity securities of MLPs considered to be return of capital, as well as for any net operating gains. Any current or deferred tax liability balance will reduce the Fund’s NAV. Upon the Fund’s sale or other disposition of a portfolio security, the Fund may be liable for previously deferred taxes. If the Fund is required to sell portfolio securities to meet redemption requests, the Fund may recognize income and gains for U.S. federal, state and local income tax purposes, which may result in additional corporate income taxes imposed on the Fund.

·   The Fund will also accrue a deferred tax asset balance, which reflects an estimate of the Fund’s future tax benefit associated with net operating losses and unrealized losses. Any deferred tax asset balance could increase the Fund’s NAV. To the extent the Fund has a deferred tax asset balance, the Fund will assess whether a valuation allowance, which would offset the value of some or all of the Fund’s deferred tax asset balance, is required, considering all positive and negative evidence related to the realization of the Fund’s deferred tax asset. The Fund intends to assess whether a valuation allowance is required to offset some or all of any deferred tax asset balance in connection with the calculation of the Fund’s NAV per share each day; however, to the extent the final valuation allowance differs from the estimates of the Fund used in calculating the Fund’s daily NAV, the application of such final valuation allowance could have a material impact on the Fund’s NAV.

·   The Fund’s current and deferred tax liability and/or asset balances are subject to numerous estimates and assumptions, including estimates of effective tax rates expected to apply to taxable income in the taxable years such balances are realized. The Fund will principally rely on information provided by MLPs regarding the tax characterization of the distributions made by such MLPs, which may not be provided to the Fund on a timely basis, to estimate the Fund’s current taxes as well as deferred tax liability and/or asset balances for purposes of financial statement reporting and determining its NAV. The Fund’s estimates regarding its current tax as well as its deferred tax liability and/or asset balances are made in good faith; however, the daily estimate of the Fund’s current taxes as well as deferred tax liability and/or asset balances used to calculate the Fund’s NAV could vary dramatically from the Fund’s actual tax liability, and, as a result, the determination of the Fund’s actual tax liability may have a material impact on the Fund’s NAV. From time to time, the Fund may modify its estimates or assumptions regarding its current and deferred tax liability and/or asset balances as new information becomes available. Modifications of the Fund’s estimates or assumptions regarding its current and deferred tax liability and/or asset balances and any applicable valuation allowance, changes in generally accepted accounting principles or related guidance or interpretations thereof, limitations imposed on net operating losses (if any) and changes in applicable tax law could result in increases or decreases in the Fund’s NAV per share, which could be material.

·   Changes in tax laws, regulations or interpretations of those laws or regulations in the future could adversely affect the Fund or the Energy Companies in which the Fund will invest.

Liquidity and Valuation Risk: Securities purchased by the Fund may be illiquid at the time of purchase or liquid at the time of purchase and subsequently become illiquid due to, among other things, events relating to the issuer of the securities, market events, operational issues, economic conditions, investor perceptions or lack of market participants. The lack of an active trading market may make it difficult to sell or obtain an accurate price for a security. If market conditions or issuer specific developments make it difficult to value securities, the Fund may value these securities using more subjective methods, such as fair value pricing. In such cases, the value determined for a security could be different than the value realized upon such security's sale. As a result, an investor could pay more than the market value when buying Fund shares or receive less than the market value when selling Fund shares. This could affect the proceeds of any redemption or the number of shares an investor receives upon purchase. Liquidity risk may also refer to the risk that the Fund may not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, unusually high volume of redemptions, or other reasons. To meet redemption requests or to raise cash to pursue other investment opportunities, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions, which may adversely affect the Fund.

Debt Securities Risk: The risks of investing in debt or fixed-income securities include (without limitation): (i) credit risk, e.g., the issuer or guarantor of a debt security may be unable or unwilling (or be perceived as unable or unwilling) to make timely principal and/or interest payments or otherwise honor its obligations; (ii) maturity risk, e.g., a debt security with a longer maturity may fluctuate in value more than one with a shorter maturity; (iii) market risk, e.g., low demand for debt securities may negatively impact their price; (iv) interest rate risk, e.g., when interest rates go up, the value of a debt security generally goes down, and when interest rates go down, the value of a debt security generally goes up (long-term
