Expenses and Fees

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (the “Shares”).

Shareholder Fees (fees paid directly from your investment)

Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None
Maximum Deferred Sales Charge (Load)	None
Maximum Sales Charge (Load) Imposed on Reinvested Dividends	None
Redemption Fee (as a percentage of amount redeemed, if applicable)	None

Acquired Fund Fees and Expenses(2)	0.03%
Total Annual Fund Operating Expenses	0.95%

⁽¹⁾ The Fund is currently only available to clients of the Fund’s investment adviser, Altair Advisers LLC (the “Adviser”) and to other investors at the Fund’s discretion. Investors in the Fund who are also clients of the Adviser will incur additional fees based on the total assets of the client under management with the Adviser. The Adviser does not receive a separate management fee from the Fund, although the Adviser is reimbursed for out-of-pocket expenses in connection with its compliance monitoring of Fund trading, up to 0.01% of the Fund’s average daily net assets. The management fee shown above reflects the aggregate fees paid by the Fund to the Sub-Advisers for the fiscal year ending August 31, 2017, plus anticipated reimbursements to the Adviser for out-of-pocket expenses. Investors in the Fund who are also clients of the Adviser should review the information provided separately by the Adviser for a discussion of fees and expenses charged by the Adviser.

⁽²⁾ Acquired Fund Fees and Expenses are indirect fees and expenses that the Fund incurs from investing in the shares of other mutual funds, including money market funds and exchange traded funds. Please note that the amount of Total Annual Fund Operating Expenses shown in the above table will differ from the “Financial Highlights” section of the Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as Acquired Fund Fees and Expenses.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year		3 Years		5 Years		10 Years
$	97	$	303	$	525	$	1,166

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). 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 Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. Portfolio turnover may vary from year to year, as well as within a year. For the most recent fiscal year, the Fund’s portfolio turnover rate was 88% of the average value of its portfolio.

Summary of Principal Investment Strategies

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets (including borrowing for investment purposes) in equity securities of small or micro-cap companies. Small or micro-cap companies are generally considered to be those whose market capitalization are, at the time the Fund makes an investment, within the range of the market capitalization of companies in the Russell Microcap Index ($8 million to $2.0 billion as of November 30, 2017), the Russell 2000^® Index ($22 million to $9.4 billion as of November 30, 2017), or the S&P SmallCap 600 Index ($62 million to $8.4 billion as of November 30, 2017). Securities of companies whose market capitalization no longer meet this definition after purchase may continue to be held by the Fund.

The Fund utilizes a “multi-manager” approach whereby the Fund’s assets are allocated to one or more sub-advisers (“Sub-Advisers”) in percentages determined at the discretion of the Fund’s investment adviser, Altair Advisers LLC (the “Adviser”). The Adviser also monitors Sub-Adviser trading with the dual objectives of maximizing each Sub-Adviser’s investment flexibility and assuring that the Fund as a whole complies with its investment restrictions. Otherwise, each Sub-Adviser acts independently from the others and utilizes its own distinct investment style in selecting securities. However, each Sub-Adviser must operate within the constraints of the Fund’s investment objective and strategies and the particular investment restrictions applicable to that Sub-Adviser.

The Sub-Advisers will implement a number of different investment strategies and styles within the small and micro-cap universe. The Sub-Advisers will implement one or more of the following investment strategies summarized below:

• Small or Micro-Cap Growth — A Sub-Adviser following a growth investment style is expected to invest primarily in small or micro-cap companies with consistent or accelerating growth in earnings, revenues, cash flow, and/or other financial metrics.

• Small or Micro-Cap Value — A Sub-Adviser following a value investment style is expected to invest primarily in small or micro-cap companies that are out of favor and/or undervalued in comparison to their peers or their growth prospects.

• Small or Micro-Cap Core — A Sub-Adviser following a core investment style is expected to invest in small or micro-cap companies that have both value characteristics and growth characteristics.

• Tax Loss Harvesting — A Sub-Adviser following a tax loss harvesting style is expected to hold a portfolio of securities that will have a pre-tax return similar to the performance of the S&P SmallCap 600 Index. The Sub-Adviser will seek to generate strong-after tax returns by timing trades to avoid realizing capital gains and to harvest losses when possible. The Fund may use losses generated from the tax loss harvesting Sub-Adviser to offset gains from other Sub-Advisers.

The Fund’s Sub-Advisers will invest primarily in equities and equity-related instruments of small and micro-cap companies. Equities and equity-related instruments include common stocks, preferred stocks, convertible securities, sponsored and unsponsored depositary receipts, warrants and rights. The Fund may participate as a purchaser in initial public offerings of securities (“IPOs”). An IPO is a company’s first offering of stock to the public. The Fund may also invest in companies that may experience unusual and possibly unique developments, or “special situations”, which may create a special opportunity for significant returns. Special situations include: significant technological improvements or important discoveries; reorganizations, recapitalizations or mergers; favorable resolutions of litigation; new management or material changes in company policies; and actual or potential changes in control of a company. The Sub-Advisers may also invest in real estate investment trusts (“REITs”), debt securities, and foreign securities (directly and through depository receipts).

Summary of Principal Risks

As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. The principal risk factors affecting shareholders’ investments in the Fund are set forth below.

2 

• Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices do not work to achieve their desired result.

• Market Risk. The net asset value (“NAV”) of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money.

• Equity Securities Risk. The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities held by the Fund.

• Small and Micro-Cap Risk. The securities of small and micro-cap companies may be more volatile in price, have wider spreads between their bid and ask prices, and have significantly lower trading volumes than the securities of larger capitalization companies. As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Fund may need a considerable amount of time to purchase or sell its positions in these securities. Some small and micro-cap companies are followed by few, if any, securities analysts, and there tends to be less publicly available information about such companies. The small and micro-cap securities in which the Fund invests may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. They generally have even more limited trading volumes and are subject to even more abrupt or erratic market price movements than are mid and large cap securities, and the Fund may be able to deal with only a few market-makers when purchasing and selling securities. Small and micro-cap companies also may have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Smaller company stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks. Moreover, the lack of an efficient market for the securities may make them difficult to value.

• Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when growth stocks are out of favor.

• Value Stock Risk. Value investing involves buying stocks that are out of favor and/or undervalued in comparison to their peers or their prospects for growth. Typically, their valuation levels are less than those of growth stocks. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market downturn and when value stocks are out of favor.

• REIT Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

• Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

• Allocation Risk. The Fund’s overall risk level will depend on the market sectors in which the Sub-Advisers are invested. Although the Fund will not concentrate in any industry, because the Fund may have significant weightings in a particular company, industry or market sector, the value of Shares may be affected by events that adversely affect that company, industry or market sector and may fluctuate more than that of a less focused fund.

3 

• Multi-Manager Dependence Risk. The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Sub-Advisers and to allocate assets to those Sub-Advisers and on each Sub-Adviser’s ability to execute the relevant strategy and select investments for the Fund. The Sub-Advisers’ investment styles may not always be complementary, which could affect the performance of the Fund and lead to higher transaction expenses as compared to a fund using a single investment management style.

• Sub-Adviser and Strategy Concentration Risk. Because the Adviser will not be subject to fixed limitations upon the amount of Fund assets that may be invested with a single Sub-Adviser or in a single investment strategy, the Fund may be more heavily exposed to the investment judgments of one or more Sub-Advisers or the possible increased risk of investing in a limited number of investment strategies.

• Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities.

• IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

• Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

• Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

• Portfolio Turnover Risk. The Adviser and Sub-Advisers will not consider portfolio turnover rate a limiting factor in making investment decisions consistent with the Fund’s investment objective and policies. Therefore, it is possible that the Fund may experience high rates of portfolio turnover. High portfolio turnover will cause the Fund to incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

ADDITIONAL INFORMATION ABOUT THE FUND’S INVESTMENTS AND RISKS

This section provides some additional information about the Fund’s investments and certain portfolio management techniques that the Fund may use. More information about the Fund’s investments and portfolio management techniques, and related risks, is included in the Statement of Additional Information (“SAI”).

The Fund’s investment objective is non-fundamental and may be changed by the Board of Directors (the “Board”) of The RBB Fund, Inc. (the “Company”) without the approval of the Fund’s shareholders. However, as a matter of policy, the Fund would not materially change its investment objective without informing shareholders at least 60 days in advance of any such change.

Equity and Equity-Related Securities. The Fund invests in all types of equity securities. Equity securities include exchange-traded and over-the-counter common and preferred stocks, warrants, rights, convertible securities, depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies and real estate investment trusts (“REITs”), and equity participations. Investments in equity securities in general are subject to market risks that may cause their prices to fluctuate over time. The value of a convertible security may not increase or decrease as rapidly as the underlying common stock. Common stocks may decline over short or even extended periods of time. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right’s or warrant’s expiration. The value of such securities convertible into equity securities, such as warrants or convertible debt, is also affected by prevailing interest rates, the credit quality of the issuer and any call provision. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. State law governing partnerships is often less restrictive than state law governing corporations. Accordingly, there may be fewer protections afforded to investors in a limited partnership than investors in a corporation. Fluctuations in the value of equity securities in which a mutual fund invests will cause the Fund’s net asset value to fluctuate. The number of issuers in the Fund’s portfolio will vary over time.

Fixed Income Investments. The Fund may invest a portion of its assets in fixed income securities. Fixed income investments include bonds, notes (including structured notes), mortgage-backed securities, asset-backed securities, convertible securities, Eurodollar and Yankee dollar instruments, preferred stocks and money market instruments. Fixed income securities may be issued by corporate and governmental issuers and may have all types of interest rate payment and reset terms, including (without limitation) fixed rate, adjustable rate, zero coupon, contingent, deferred, payment-in-kind and auction rate features. The principal debt investments of the Fund will be fixed and floating rate securities with no reset terms.

The credit quality of securities held in the Fund’s portfolio is determined at the time of investment. If a security is rated differently by multiple ratings organizations, the Fund treats the security as being rated in the higher rating category. The Fund may invest in fixed income securities that are not investment grade but are rated as low as B by Moody’s Investors Service or by S&P Global Ratings (or their equivalents, or, if unrated, determined by the Adviser or applicable Sub-Adviser to be of comparable credit quality). The Fund may choose not to sell securities that are downgraded below the Fund’s minimum accepted credit rating after their purchase. Periods of rising interest rates may result in decreased liquidity and increased volatility in the fixed income markets.

Foreign Securities. The Fund may invest in securities of foreign issuers that are traded or denominated in U.S. dollars (including equity securities of foreign issuers trading in U.S. markets) through American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”) or International Depositary Receipts (“IDRs”). Depositary receipts may be available through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the security underlying the receipt and the depository, whereas an unsponsored facility is established by the depository without participation by the issuer of the underlying security. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders.

8 

In addition, the Fund may invest in securities traded or denominated in foreign currencies and in multinational currencies such as the Euro. The Fund will value its securities and other assets in U.S. dollars. Investments in securities of foreign entities and securities denominated or traded in foreign currencies involve special risks. These include possible political and economic instability and the possible imposition of exchange controls or other restrictions on investments. Changes in foreign currency rates relative to the U.S. dollar will affect the U.S. dollar value of the Fund’s assets denominated or quoted in currencies other than the U.S. dollar. Emerging market investments offer the potential for significant gains but also involve greater risks than investing in more developed countries. Political or economic instability, lack of market liquidity and government actions such as currency controls or seizure of private business or property may be more likely in emerging markets.

Interest Rate Risk. During periods of rising interest rates, the market value of the Fund’s fixed-income securities will tend to be lower than prevailing market interest rates. In periods of falling interest rates, the market value of the Fund’s fixed-income securities generally will tend to be higher than prevailing market interest rates. Prices of longer-term fixed income securities are typically more sensitive to changes in interest rates than prices of shorter-term fixed-income securities.

Credit/Default Risk. The credit rating of an issuer or guarantor of a security in which the Fund invests may be lowered or an issuer or guarantor of a security or the counterparty to a derivatives contract or a repurchase agreement may default on its payment obligations.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase or sell. The Fund’s investments in illiquid securities may reduce the returns of the Fund because it may be unable to sell the illiquid securities at an advantageous time or price. Illiquidity can be caused by a drop in overall market trading volume, an inability to find a ready buyer, or legal restrictions on the securities’ resale. Certain securities that were liquid when purchased may later become illiquid, particularly in times of overall economic distress.

Convertible Securities Risk. Convertible securities have characteristics of both equity and fixed income securities. The value of a convertible security tends to move with the market value of the underlying stock, but may also be affected by interest rates, the credit quality of the issuer and any call provisions. In particular, when interest rates rise, fixed income securities will decline in value. Convertible securities frequently have speculative characteristics and may be acquired without regard to minimum quality ratings. Lower quality convertible securities, also known as “junk bonds,” involve greater risk of default or price changes due to the issuer’s creditworthiness. The market prices of these securities may fluctuate more than those of higher quality securities and may decline significantly in periods of general economic difficulty, which may follow periods of rising interest rates. Securities in the lowest quality category may present the risk of default, or may be in default.

REIT Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

Portfolio Turnover. The Fund may engage in active and frequent trading, resulting in high portfolio turnover. This may lead to the realization and distribution to shareholders of higher capital gains, increasing their tax liability. A portfolio turnover rate of 100% is considered to be high. Frequent trading may also increase transaction costs, which could detract from the Fund’s performance.

Temporary Investments. The Fund may depart from its principal investment strategy in response to adverse market, economic, political or other conditions by taking temporary defensive positions (up to 100% of its assets) in all types of money market and short-term debt securities. In response to such conditions, the Fund may also utilize derivatives, including purchasing put options. A put option gives the purchaser of the option, upon payment of a premium, the right to sell, and the seller the obligation to buy, the underlying security, index, currency or other instrument at the exercise price. If the Fund were to take a temporary defensive position, it may be unable for a time to achieve its investment objective.

MANAGEMENT OF THE FUND

Investment Adviser

Altair Advisers LLC, a registered investment adviser located at 303 W. Madison, Suite 600, Chicago, Illinois 60606, provides investment advisory services to the Fund subject to the general supervision of the Board. The Adviser was founded in June 2002. As of September 30, 2017, the Adviser had over $4.4 billion in assets under management.

The Fund is currently only available to clients of the Adviser and to other investors at the Fund’s discretion. The Adviser does not receive a separate management fee from the Fund. However, pursuant to the Fund’s investment advisory agreement with the Adviser, the Adviser is entitled to receive reimbursement for out-of-pocket expenses it incurs in connection with its compliance monitoring of Fund trading, up to 0.01% of the Fund’s average daily net assets.

The Fund is managed by the Adviser and one or more Sub-Advisers unaffiliated with the Adviser. The Adviser also has the ultimate responsibility to oversee the Sub-Advisers, and to recommend their hiring, termination, and replacement, subject to approval by the Board. The Adviser has an investment team that is jointly responsible for the day-to-day management of the Fund. The investment team consists of Steven B. Weinstein, Jason M. Laurie, Bryan R. Malis, Donald J. Sorota and David J. Lin.

Sub-Advisers

The Company and the Adviser have received an exemptive order from the SEC with respect to the Fund that permits the Adviser to engage or terminate a Sub-Adviser, and to enter into and materially amend an existing sub-advisory agreement, upon the approval of the Board, without obtaining shareholder approval. This arrangement has been approved by the Board. Consequently, under the exemptive order, the Adviser has the right to hire, terminate and replace Sub-Advisers when the Board and the Adviser feel that a change would benefit the Fund. The exemptive order enables the Fund to operate with greater efficiency and without incurring the expense and delays associated with obtaining shareholder approval of sub-advisory agreements.

The Sub-Advisers provide investment advisory services to the portion of the Fund’s portfolio allocated to them by the Adviser. The Adviser and the Fund have entered into sub-advisory agreements with the following Sub-Advisers to manage the Fund, subject to supervision of the Adviser and the Board, and in accordance with the investment goal and restrictions of the Fund. For their services, each Sub-Adviser is entitled to receive a fee based upon a percentage of the Fund’s average daily net assets, which will be paid by the Fund and not by the Adviser. The Adviser selects Sub-Advisers based upon the Sub-Adviser’s skills in managing assets pursuant to particular investment styles and strategies. The Adviser monitors existing Sub-Advisers based on their investment styles, strategies, and results in managing assets for specific asset classes. Each Sub-Adviser will have discretion to select portfolio securities for its portion of the Fund, but must select those securities according to the Fund’s investment objectives and restrictions. The Fund is not required to invest with any minimum number of Sub-Advisers, and does not have minimum or maximum limitations with respect to allocations of assets to any Sub-Adviser. The Adviser may change the allocation of the Fund’s assets among the available Sub-Advisers, and may add or remove Sub-Advisers, at any time, which may change the sub-advisory fees payable by the Fund. However, in no event will the total sub-advisory fees exceed the annual rate of 1.00% of the Fund’s average daily net assets.

The SAI provides additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers and the portfolio managers’ ownership of shares of the Fund.

A discussion regarding the basis for the Board’s approval of the Fund’s investment advisory agreement with the Adviser and sub-advisory agreements with the Sub-Advisers is available in the Fund’s annual report to shareholders dated August 31, 2017.

SHAREHOLDER INFORMATION

Pricing of Fund Shares

The Shares are priced at their net asset value (“NAV”). The NAV per Share of the Fund is calculated as follows:

		Value of Assets Attributable to the Shares
NAV =	-	Value of Liabilities Attributable to the Shares
		Number of Outstanding Shares of the Shares

The Fund’s NAV is calculated once daily at the close of regular trading hours on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m. Eastern time) on each day the NYSE is open. The NYSE is generally open Monday through Friday, except national holidays. The NYSE also may be closed on national days of mourning or due to natural disaster or other extraordinary events or emergency. The Fund will effect purchases of Shares at the NAV next determined after receipt by the Transfer Agent of your purchase order in good order. The Fund will effect redemptions of Shares at the NAV next calculated after receipt by the Fund’s Transfer Agent of your redemption request in good order as described below.

The Fund’s equity securities listed on any national or foreign exchange market system will be valued at the last sale price, except for the National Association of Securities Dealers Automatic Quotation System (“NASDAQ”). Equity securities listed on the NASDAQ will be valued at the official closing price. Equity securities traded in the over-the-counter market are valued at their closing prices. If there were no transactions on that day, equity securities will be valued at the mean of the last bid and ask prices prior to the market close. Fixed income securities are valued using an independent pricing service, which considers such factors as security prices, yields, maturities and ratings, and are deemed representative of market value at the close of the market. Foreign securities, currencies and other securities denominated in foreign currencies are translated into U.S. dollars at the exchange rate of such currencies against the U.S. dollar provided by a pricing service. All assets denominated in foreign currencies will be converted into U.S. dollars at the exchange rates in effect at the time of valuation. If the Fund holds foreign equity securities, the calculation of the Fund’s NAV will not occur at the same time as the determination of the value of the foreign equities securities in the Fund’s portfolio, since these securities are traded on foreign exchanges.

13 

Investments in other open-end investment companies are valued based on the NAV of those investment companies (which may use fair value pricing as discussed in their prospectuses). Investments in exchange-traded funds, REITs and closed-end funds will be valued at their market price.

If market quotations are unavailable or deemed unreliable by the Fund’s administrator, in consultation with the Adviser and Sub-Advisers, securities will be valued by the Adviser and Sub-Advisers in accordance with procedures adopted by the Board and under the Board’s ultimate supervision. In addition, the prices of foreign securities may be affected by events that occur after the close of a foreign market but before the Fund prices its Shares. In such instances, a foreign security may be fair valued in accordance with procedures adopted by the Board. Relying on prices supplied by pricing services or dealers or using fair valuation involves the risk that the values used by the Fund to price its investments may be higher or lower than the values used by other investment companies and investors to price the same investments.

Market Timing

In accordance with the policy adopted by its Board, the Company discourages and does not accommodate market timing and other excessive trading practices. Purchases should be made with a view to longer-term investment only. Excessive short-term (market timing) trading practices may disrupt portfolio management strategies, increase brokerage and administrative costs, harm Fund performance and result in dilution in the value of Shares held by long-term shareholders. The Company and the Adviser reserve the right to (i) reject a purchase or exchange order, (ii) delay payment of immediate cash redemption proceeds for up to seven calendar days, (iii) revoke a shareholder’s privilege to purchase Shares (including exchanges), or (iv) limit the amount of any exchange involving the purchase of Shares. An investor may receive notice that their purchase order or exchange has been rejected after the day the order is placed or after acceptance by a financial intermediary. It is currently expected that a shareholder would receive notice that its purchase order or exchange has been rejected within 48 hours after such purchase order or exchange has been received by the Company in good order. The Company and the Adviser will not be liable for any loss resulting from rejected purchase orders. To minimize harm to the Company and its shareholders (or the Adviser), the Company (or the Adviser) will exercise its right if, in the Company’s (or the Adviser’s) judgment, an investor has a history of excessive trading or if an investor’s trading, in the judgment of the Company (or the Adviser), has been or may be disruptive to the Fund. No waivers of the provisions of the policy established to detect and deter market timing and other excessive trading activity are permitted that would harm the Fund and its shareholders or would subordinate the interests of the Fund and its shareholders to those of the Adviser or any affiliated person or associated person of the Adviser.

Pursuant to the policy adopted by the Board, the Adviser has developed criteria that it uses to identify trading activity that may be excessive. The Adviser reviews on a regular, periodic basis available information related to the trading activity in the Fund in order to assess the likelihood that the Fund may be the target of excessive trading. As part of its excessive trading surveillance process, the Adviser, on a periodic basis, examines transactions that exceed certain monetary thresholds or numerical limits within a period of time. If, in its judgment, the Adviser detects excessive, short-term trading, it may reject or restrict a purchase request and may further seek to close an investor’s account with the Fund. The Adviser may modify its surveillance procedures and criteria from time to time without prior notice regarding the detection of excessive trading or to address specific circumstances. The Adviser will apply the criteria in a manner that, in its judgment, will be uniform.

14 

If necessary, the Company may prohibit additional purchases of Shares by a financial intermediary or by certain customers of the financial intermediary. Financial intermediaries may also monitor their customers’ trading activities in the Fund. The criteria used by intermediaries to monitor for excessive trading may differ from the criteria used by the Company. If a financial intermediary fails to enforce the Company’s excessive trading policies, the Company may take certain actions, including terminating the relationship.

There is no assurance that the Fund will be able to identify market timers, particularly if they are investing through intermediaries.

Purchase of Fund Shares

Shares of the Fund are currently only available to new and existing clients of the Adviser and to other investors at the Fund’s discretion. Shares representing interests in the Fund are offered continuously for sale by Quasar Distributors, LLC (the “Distributor”).

General. You may purchase Shares of the Fund at the NAV per Share next calculated after your order is received by the Transfer Agent in good order as described below. The Fund’s NAV is calculated once daily at the close of regular trading hours on the NYSE (generally 4:00 p.m. Eastern time) on each day the NYSE is open. After an initial purchase is made, the Transfer Agent will set up an account for you on the Company records. There is no minimum investment amount for initial or subsequent investments. You can only purchase Shares of the Fund on days the NYSE is open and through the means described below.

Purchases Through Intermediaries. Shares of the Fund may also be available through certain brokerage firms, financial institutions and other industry professionals (collectively, “Service Organizations”). Certain features of the Shares, such as the initial and subsequent investment minimums and certain trading restrictions, may be modified or waived by Service Organizations. Service Organizations may impose minimum investment requirements. Service Organizations may also impose transaction or administrative charges or other direct fees, which charges and fees would not be imposed if Shares are purchased directly from the Company. Therefore, you should contact the Service Organization acting on your behalf concerning the fees (if any) charged in connection with a purchase or redemption of Shares and should read this Prospectus in light of the terms governing your accounts with the Service Organization. Service Organizations will be responsible for promptly transmitting client or customer purchase and redemption orders to the Company in accordance with their agreements with the Company or its agent and with clients or customers. Service Organizations or, if applicable, their designees that have entered into agreements with the Company or its agent may enter confirmed purchase orders on behalf of clients and customers, with payment to follow no later than the Company’s pricing on the following business day. If payment is not received by such time, the Service Organization could be held liable for resulting fees or losses. The Company will be deemed to have received a purchase or redemption order when a Service Organization, or, if applicable, its authorized designee, accepts a purchase or redemption order in good order if the order is actually received by the Company in good order not later than the next business morning. If a purchase order is not received by the Fund in good order, the Transfer Agent will contact the financial intermediary to determine the status of the purchase order. Orders received by the Company in good order will be priced at the Fund’s NAV next computed after such orders are deemed to have been received by the Service Organization or its authorized designee.

For administration, subaccounting, transfer agency and/or other services, the Fund or the Adviser may pay Service Organizations and certain recordkeeping organizations a fee (the “Service Fee”). The Service Fee payable to any one Service Organization is determined based upon a number of factors, including the nature and quality of services provided, the operations processing requirements of the relationship and the standardized fee schedule of the Service Organization or recordkeeper.

Initial Investment By Mail. An account may be opened by completing and signing an account application and mailing it to the Transfer Agent at the address noted below, together with a check payable to the Adara Smaller Companies Fund.

15 

Regular Mail:	Overnight Mail:

The Fund does not consider the U.S. Postal Service or other independent delivery services to be its agents. Therefore, deposit in the mail or with such services, or receipt at U.S. Bancorp Fund Services, LLC’s post office box, of purchase orders or redemption requests does not constitute receipt by the transfer agent of the Fund. Receipt of purchase orders or redemption requests is based on when the order is received at the Transfer Agent’s offices.

All checks must be in U.S. Dollars drawn on a domestic bank. The Fund will not accept payment in cash or money orders. The Fund does not accept post-dated checks or any conditional order or payment. To prevent check fraud, the Fund will not accept third party checks, Treasury checks, credit card checks, traveler’s checks or starter checks for the purchase of shares.

Shares will be purchased at the NAV next computed after the time the application and funds are received in proper order and accepted by the Fund. The Transfer Agent will charge a $25 fee against a shareholder’s account, in addition to any loss sustained by the Fund, for any payment that is returned. It is the policy of the Fund not to accept applications under certain circumstances or in amounts considered disadvantageous to shareholders. The Fund reserves the right to reject any application.

Initial Investment By Wire. If you are making your first investment in the Fund, before you wire funds, the Transfer Agent must have a completed account application. You may mail or overnight deliver your account application to the Transfer Agent. Upon receipt of your completed account application, the Transfer Agent will establish an account for you.

Subsequent Investments By Wire. Before sending your wire, please contact the Transfer Agent to advise them of your intent to wire funds. This will ensure prompt and accurate credit upon receipt of your wire.

Additional Investments. Additional investments may be made at any time by purchasing Shares of the Fund at the NAV per Share of the Fund by mailing a check to the Transfer Agent at the address noted under “Initial Investment by Mail” (payable to Adara Smaller Companies Fund) or by wiring monies to U.S. Bank, N.A., as outlined under “Initial Investment by Wire.” Notification must be given to the Transfer Agent at 1-844-261-6482 prior to 4:00 p.m., Eastern time, on the wire date. Initial and additional purchases made by check or electronic funds transfer through the ACH network cannot be redeemed until payment of the purchase has been collected. This may take up to 15 calendar days from the purchase date.

16 

Automatic Investment Plan. Once your account has been opened with the initial minimum investment, you may make additional purchases at regular intervals through an automatic investment plan (the “Automatic Investment Plan”). The Automatic Investment Plan provides a convenient method to have monies deducted from your bank account, for investment into the Fund, on a monthly or quarterly basis. In order to participate in the Automatic Investment Plan, each purchase must be in the amount of $250 or more, and your financial institution must be a member of the Automated Clearing House (ACH) network. If your bank rejects your payment, the Fund’s transfer agent will charge a $25 fee to your account. To begin participating in the Automatic Investment Plan, please complete the Automatic Investment Plan section on the account application or call the Fund’s transfer agent at 1-844-261-6482 for instructions. Any request to change or terminate your Automatic Investment Plan should be submitted to the Transfer Agent five (5) days prior to effective date.

You may be charged a $15 annual account maintenance fee for each retirement account up to a maximum of $30 annually and a $25 fee for transferring assets to another custodian or for closing a retirement account.

Purchases in Kind. In certain circumstances, Shares of the Fund may be purchased “in kind” (i.e. in exchange for securities, rather than cash). The securities rendered in connection with an in-kind purchase must be liquid securities that are not restricted as to transfer and have a value that is readily ascertainable in accordance with the Company’s valuation procedures. Securities accepted by the Fund will be valued, as set forth in this Prospectus, as of the time of the next determination of net asset value after such acceptance. The Shares of the Fund that are issued to the investor in exchange for the securities will be determined as of the same time. All dividend, subscription, or other rights that are reflected in the market price of accepted securities at the time of valuation become the property of the Fund and must be delivered to the Fund by the investor upon receipt from the issuer. The Fund will not accept securities in exchange for its Shares unless such securities are, at the time of the exchange, eligible to be held by the Fund and satisfy such other conditions as may be imposed by the Adviser or the Company. Purchases in-kind may result in the recognition of gain or loss for federal income tax purposes on the securities transferred to the Fund.

Other Purchase Information. The Company reserves the right, in its sole discretion, to suspend the offering of Shares or to reject purchase orders when, in the judgment of management, such suspension or rejection is in the best interest of the Fund. The Adviser will monitor the Fund’s total assets and may, subject to Board approval, decide to close the Fund at any time to new investments or to new accounts due to concerns that a significant increase in the size of the Fund may adversely affect the implementation of the Fund’s strategy. The Adviser, subject to Board approval, may also choose to reopen the Fund to new investments at any time, and may subsequently close the Fund again should concerns regarding the Fund’s size recur. If the Fund closes to new investments, the Fund may be offered only to certain existing shareholders of the Fund and certain other persons who may be subject to cumulative, maximum purchase amounts, as follows:

a. Persons who already hold Shares of the closed Fund directly or through accounts maintained by brokers by arrangement with the Adviser;

b. Existing and future clients of financial advisers and planners whose clients already hold Shares of the closed Fund;

c. Employees of the Adviser and their spouses, parents and children; and

d. Directors of the Company.

Distributions to all shareholders of the closed Fund will continue to be reinvested unless a shareholder elects otherwise. The Adviser, subject to the Board’s discretion, reserves the right to implement other purchase limitations at the time of closing, including limitations on current shareholders.

Purchases of the Shares will be made in full and fractional Shares of the Fund calculated to three decimal places.

17 

Certificates for Shares will not be issued.

Good Order. A purchase request is considered to be in good order when the purchase request includes the name of the Fund, the dollar amount of shares to be purchased, your account application or investment stub, and a check payable to the Fund. Purchase requests not in good order may be rejected.

Customer Identification Program. Federal law requires the Company to obtain, verify and record identifying information, which may include the name, residential or business street address, date of birth (for an individual), social security or taxpayer identification number or other identifying information for each investor who opens or reopens an account with the Company. Applications without the required information, or without any indication that a social security or taxpayer identification number has been applied for, may not be accepted. After acceptance, to the extent permitted by applicable law or its customer identification program, the Company reserves the right (a) to place limits on transactions in any account until the identity of the investor is verified; or (b) to refuse an investment in a Company portfolio or to involuntarily redeem an investor’s Shares and close an account in the event that an investor’s identity is not verified. The Company and its agents will not be responsible for any loss in an investor’s account resulting from the investor’s delay in providing all required identifying information or from closing an account and redeeming an investor’s Shares when an investor’s identity cannot be verified.

Redemption of Fund Shares

You may redeem Shares at the next NAV calculated after a redemption request is received by the Transfer Agent in good order. The Fund’s NAV is calculated once daily at the close of regular trading hours on the NYSE (generally 4:00 p.m. Eastern time) on each day the NYSE is open. You can only redeem Shares of the Fund on days the NYSE is open and through the means described below. You may redeem Fund Shares by mail, or, if you are authorized, by telephone. The value of Shares redeemed may be more or less than the purchase price, depending on the market value of the investment securities held by the Fund.

Redemption By Mail. Your redemption request should be addressed to Adara Smaller Companies Fund, c/o U.S. Bancorp Fund Services, LLC, P.O. Box 701, Milwaukee, WI 53201-0701, or for overnight delivery to Adara Smaller Companies Fund, c/o U.S. Bancorp Fund Services, LLC, 615 East Michigan Street, Milwaukee, WI 53202.

The Fund does not consider the U.S. Postal Service or other independent delivery services to be its agents. Therefore, deposit in the mail or with such services, or receipt at U.S. Bancorp Fund Services, LLC’s post office box, of purchase orders or redemption requests does not constitute receipt by the Transfer Agent of the Fund. Receipt of purchase orders or redemption requests is based on when the order is received at the Transfer Agent’s offices.

Signature guarantees will generally be accepted from domestic banks, brokers, dealers, credit unions, national securities exchanges, registered securities associations, clearing agencies and savings associations, as well as from participants in the New York Stock Exchange Medallion Signature Program and the Securities Transfer Agents Medallion Program (“STAMP”). A notary public is not an acceptable signature guarantor.

A signature guarantee, from either a Medallion program member or a non-Medallion program member, is required in the following situations:

• If ownership is being changed on your account;

• When redemption proceeds are payable or sent to any person, address or bank account not on record; and

• For all redemptions in excess of $50,000 from any shareholder account.

The Fund may waive any of the above requirements in certain instances. In addition to the situations described above, the Fund and/or the Transfer Agent reserve the right to require a signature guarantee in other instances based on the circumstances relative to the particular situation.

Nonfinancial transactions, including establishing or modifying certain services on an account, may require a signature guarantee, signature verification from a Signature Validation Program member, or other acceptable form of authentication from a financial institution source.

18 

Redemption By Telephone. In order to utilize the telephone redemption option, you must indicate that option on your Account Application. You may then initiate a redemption of Shares in the amount of up to $50,000 by calling the Transfer Agent at 1-844-261-6482.

Investors may have a check sent to the address of record, proceeds may be wired to a shareholder’s bank account of record, or funds may be sent via electronic funds transfer through the Automated Clearing House (ACH) network, also to the bank account of record. Wires are subject to a $15 fee paid by the investor, but the investor does not incur any charge when proceeds are sent via the ACH system.

Once a telephone transaction has been placed, it cannot be canceled or modified after the close of regular trading on the NYSE (generally, 4:00 p.m., Eastern time).

Telephone trades must be received by or prior to market close. During periods of high market activity, shareholders may encounter higher than usual call waits. Please allow sufficient time to place your telephone transaction.

Before executing an instruction received by telephone, the Transfer Agent will use reasonable procedures to confirm that the telephone instructions are genuine. The telephone call may be recorded and the caller may be asked to verify certain personal identification information. If the Fund or its agents follow these procedures, they cannot be held liable for any loss, expense or cost arising out of any telephone redemption request that is reasonably believed to be genuine. This includes fraudulent or unauthorized requests. If an account has more than one owner or authorized person, the Fund will accept telephone instructions from any one owner or authorized person.

IRA and Other Retirement Plan Redemptions. If you have an IRA, you must indicate on your written redemption request whether or not to withhold federal income tax. Redemption requests failing to indicate an election to have tax withheld will be subject to 10% withholding.

Shares held in IRA accounts may be redeemed by telephone at 1-844-261-6484. Investors will be asked whether or not to withhold taxes from any distribution.

Involuntary Redemption. The Fund reserves the right to redeem a shareholder’s account in the Fund at any time the value of the account falls below $5,000 as the result of a redemption or an exchange request. Shareholders will be notified in writing that the value of their account in the Fund is less than $5,000 and will be allowed 30 days to make additional investments before the redemption is processed. The transaction fee applicable to the Fund will not be charged when Shares are involuntarily redeemed.

The Fund may assert the right to redeem your Shares at current NAV at any time and without prior notice if, and to the extent that, such redemption is necessary to reimburse the Fund for any loss sustained by reason of your failure to make full payment for Shares of the Fund you previously purchased or subscribed for.

Other Redemption Information. Redemption proceeds for Shares of the Fund recently purchased by check or electronic funds transfer through the ACH network may not be distributed until payment for the purchase has been collected, which may take up to fifteen calendar days from the purchase date. Shareholders can avoid this delay by utilizing the wire purchase option.

Other than as described above, payment of the redemption proceeds will be made within seven days after receipt of an order for a redemption. The Company may suspend the right of redemption or postpone the date at times when the NYSE is closed or under any emergency circumstances as determined by the SEC. The Fund will typically expect to meet redemption requests by paying out proceeds from cash or cash equivalent portfolio holdings, or by selling portfolio securities. In stressed market conditions, redemption methods may include redeeming in kind.

If the Board determines that it would be detrimental to the best interests of the remaining shareholders of the Fund to make payment wholly or partly in cash, redemption proceeds may be paid in whole or in part by an in-kind distribution of readily marketable securities held by the Fund instead of cash in conformity with applicable rules of the SEC. If a shareholder receives redemption proceeds in-kind, the shareholder will bear the market risk of the securities received in the redemption until their disposition and should expect to incur transaction costs upon the disposition of the securities. The Company has elected, however, to be governed by Rule 18f-1 under the 1940 Act, so that the Fund is obligated to redeem its Shares solely in cash up to the lesser of $250,000 or 1% of its NAV during any 90-day period for any one shareholder of the Fund.

19 

Good Order. A redemption request is considered to be in good order when the redemption request includes the name of the Fund, the number of shares or dollar amount to be redeemed, the account number, and signatures by all of the shareholders whose names appear on the account registration with a signature guarantee, if applicable. Redemption requests not in good order may be delayed.

Dividends and Distributions

The Fund will distribute substantially all of its net investment income and net realized capital gains, if any, to its shareholders. All distributions are reinvested in the form of additional full and fractional Shares of the Fund unless a shareholder elects otherwise.

The Fund will declare and pay dividends from net investment income annually. Net realized capital gains (including net short-term capital gains), if any, will be distributed by the Fund at least annually.

The Fund may pay additional distributions and dividends at other times if necessary for the Fund to avoid U.S. federal tax. The Fund’s distributions and dividends, whether received in cash or reinvested in additional Shares, are subject to U.S. federal income tax.

All distributions will be reinvested in Fund shares unless you elect to receive cash. If you elect to receive distributions and/or capital gains paid in cash, and the U.S. Postal Service cannot deliver the check, or if a check remains outstanding for six months, the Fund reserves the right to reinvest the distribution check in your account, at the Fund’s current net asset value, and to reinvest all subsequent distributions. You may change the distribution option on your account at any time by telephone or in writing. You should notify the Transfer Agent in writing or by telephone at least five (5) days prior to the next distribution.

More Information About Taxes

The following is a summary of certain United States tax considerations relevant under current law, which may be subject to change in the future. Except where otherwise indicated, the discussion relates to investors who are individual United States citizens or residents. You should consult your tax adviser for further information regarding federal, state, local and/or foreign tax consequences relevant to your specific situation.

Distributions. The Fund contemplates distributing as dividends each year all or substantially all of its taxable income, including its net capital gain (the excess of net long-term capital gain over net short-term capital loss). Except as otherwise discussed below, you will be subject to federal income tax on Fund distributions regardless of whether they are paid in cash or reinvested in additional Shares. Fund distributions attributable to short-term capital gains and net investment income will generally be taxable to you as ordinary income, except as discussed below.

Distributions attributable to the net capital gain of the Fund will be taxable to you as long-term capital gain, no matter how long you have owned your Shares. The maximum long-term capital gain rate applicable to individuals, estates, and trusts is currently 23.8% (which includes a 3.8% Medicare tax). You will be notified annually of the tax status of distributions to you.

Distributions of “qualifying dividends” will also generally be taxable to you at long-term capital gain rates, as long as certain requirements are met. In general, if 95% or more of the gross income of the Fund (other than net capital gain) consists of dividends received from domestic corporations or ‘qualified” foreign corporations (“qualifying dividends”), then all distributions paid by the Fund to individual shareholders will be taxed at long-term capital gains rates. But if less than 95% of the gross income of the Fund (other than net capital gain) consists of qualifying dividends, then distributions paid by the Fund to individual shareholders will be qualifying dividends only to the extent they are derived from qualifying dividends earned by the Fund. For the lower rates to apply, you must have owned your Fund shares for at least 61 days during the 121-day period beginning on the date that is 60 days before the Fund’s ex-dividend date (and the Fund will need to have met a similar holding period requirement with respect to the shares of the corporation paying the qualifying dividend). The amount of the Fund’s distributions that qualify for this favorable treatment may be reduced as a result of the Fund’s securities lending activities (if any), a high portfolio turnover rate or investments in debt securities or non-qualified foreign corporations.

20 

Distributions from the Fund will generally be taxable to you in the taxable year in which they are paid, with one exception. Distributions declared by the Fund in October, November or December and paid in January of the following year are taxed as though they were paid on December 31.

A portion of distributions paid by the Fund to shareholders that are corporations may also qualify for the dividends-received deduction for corporations, subject to certain holding period requirements and debt financing limitations. The amount of the dividends qualifying for this deduction may, however, be reduced as a result of the Fund’s securities lending activities (if any), by a high portfolio turnover rate or by investments in debt securities or foreign corporations.

If you purchase Shares just before a distribution, the purchase price will reflect the amount of the upcoming distribution, but you will be taxed on the entire amount of the distribution received, even though, as an economic matter, the distribution simply constitutes a return of capital. This is known as “buying into a dividend.”

Sales of Shares. You will generally recognize taxable gain or loss for federal income tax purposes on a sale or redemption of your Shares based on the difference between your tax basis in the Shares and the amount you receive for them. Generally, you will recognize long-term capital gain or loss if you have held your Shares for over twelve months at the time you dispose of them.

Any loss realized on Shares held for six months or less will be treated as a long-term capital loss to the extent of any capital gain dividends that were received on the Shares. Additionally, any loss realized on a disposition of Shares of the Fund may be disallowed under “wash sale” rules to the extent the Shares disposed of are replaced with other Shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the Shares are disposed of, such as pursuant to a dividend reinvestment in Shares of the Fund. If disallowed, the loss will be reflected in an upward adjustment to the basis of the Shares acquired.

The Fund (or relevant broker or financial adviser) is required to compute and report to the Internal Revenue Service (“IRS”) and furnish to Fund shareholders cost basis information when Shares are sold. The Fund has elected to use the average cost method, unless you instruct the Fund to use a different IRS-accepted cost basis method, or choose to specifically identify your Shares at the time of each sale. If your account is held by your broker or other financial adviser, they may select a different cost basis method. In these cases, please contact your broker or other financial adviser to obtain information with respect to the available methods and elections for your account. You should carefully review the cost basis information provided by the Fund and make any additional basis, holding period or other adjustments that are required when reporting these amounts on your federal and state income tax returns. Fund shareholders should consult with their tax advisers to determine the best IRS-accepted cost basis method for their tax situation and to obtain more information about how the cost basis reporting requirements apply to them.

IRAs and Other Tax-Qualified Plans. The one major exception to the preceding tax principles is that distributions on, and sales and redemptions of, Shares held in an IRA (or other tax-qualified plan) will not be currently taxable unless such Shares were acquired with borrowed funds.

Backup Withholding. The Fund may be required in certain cases to withhold and remit to the IRS a percentage of taxable dividends or gross proceeds realized upon sale payable to shareholders who have failed to provide a correct tax identification number in the manner required, or who are subject to withholding by the IRS for failure to properly include on their return payments of taxable interest or dividends, or who have failed to certify to the Fund that they are not subject to backup withholding when required to do so or that they are “exempt recipients.” The current backup withholding rate is currently 28%.

U.S. Tax Treatment of Foreign Shareholders. Generally, nonresident aliens, foreign corporations and other foreign investors are subject to a 30% withholding tax on dividends paid by a U.S. corporation, although the rate may be reduced for an investor that is a qualified resident of a foreign country with an applicable tax treaty with the United States. In the case of a regulated investment company such as the Fund, however, certain categories of dividends are exempt from the 30% withholding tax. These generally include dividends attributable to the Fund’s net capital gains (the excess of net long-term capital gains over net short-term capital loss) and dividends attributable to the Fund’s interest income from U.S. obligors and dividends attributable to net short-term capital gains of the Fund.

21 

Foreign shareholders will generally not be subject to U.S. tax on gains realized on the sale or redemption of shares in the Fund, except that a nonresident alien individual who is present in the United States for 183 days or more in a calendar year will be taxable on such gains and on capital gain dividends from the Fund.

In contrast, if a foreign investor conducts a trade or business in the United States and the investment in the Fund is effectively connected with that trade or business, then the foreign investor’s income from the Fund will generally be subject to U.S. federal income tax at graduated rates in a manner similar to the income of a U.S. citizen or resident.

The Fund will also generally be required to withhold 30% tax on certain payments to foreign entities that do not provide a Form W-8BEN-E that evidences their compliance with, or exemption from, specified information reporting requirements under the Foreign Account Tax Compliance Act.

All foreign investors should consult their own tax advisers regarding the tax consequences in their country of residence of an investment in the Fund.

Shares of the Fund have not been registered for sale outside of the United States and certain United States territories.

State and Local Taxes. You may also be subject to state and local taxes on income and gain from Fund shares. State income taxes may not apply, however, to the portions of the Fund’s distributions, if any, that are attributable to interest on U.S. government securities. You should consult your tax adviser regarding the tax status of distributions in your state and locality.

More information about taxes is contained in the SAI.

Additional Information

Lost Shareholders, Inactive Accounts and Unclaimed Property. It is important that the Fund maintains a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned to the Fund. Based upon statutory requirements for returned mail, the Fund will attempt to locate the shareholder or rightful owner of the account. If the Fund is unable to locate the shareholder, then it will determine whether the shareholder’s account can legally be considered abandoned. Your mutual fund account may be transferred to the state government of your state of residence if no activity occurs within your account during the “inactivity period” specified in your state’s abandoned property laws. The Fund is legally obligated to escheat (or transfer) abandoned property to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. The shareholder’s last known address of record determines which state has jurisdiction. Please proactively contact the Transfer Agent at 1-844-261-6482 (toll free) at least annually to ensure your account remains in active status.

If you are a resident of the state of Texas, you may designate a representative to receive notifications that, due to inactivity, your mutual fund account assets may be delivered to the Texas Comptroller. Please contact the Transfer Agent if you wish to complete a Texas Designation of Representative form.

NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY REPRESENTATIONS NOT CONTAINED IN THIS PROSPECTUS OR IN THE FUND’S SAI INCORPORATED HEREIN BY REFERENCE, IN CONNECTION WITH THE OFFERING MADE BY THIS PROSPECTUS AND, IF GIVEN OR MADE, SUCH REPRESENTATIONS MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY THE COMPANY OR ITS DISTRIBUTOR. THIS PROSPECTUS DOES NOT CONSTITUTE AN OFFERING BY THE COMPANY OR BY THE DISTRIBUTOR IN ANY JURISDICTION IN WHICH SUCH OFFERING MAY NOT LAWFULLY BE MADE.

APPENDIX A

Prior Performance of Similarly Advised Accounts

The Sub-Advisers have experience in managing other accounts with substantially similar investment objectives, policies and strategies as the portion of the Fund’s portfolio allocated to them by the Adviser. The tables below are provided to illustrate the past performance of each Sub-Adviser in managing all of its other similarly advised accounts and does not represent the performance of the Fund. Investors should not consider this performance information as a substitute for the performance of the Fund, nor should investors consider this information as an indication of the future performance of the Fund or of the Sub-Advisers. This performance history is net of all fees (including any applicable sales loads) charged to investors in the other accounts. The composite includes other accounts that pay lower expenses than those paid by shareholders of the Fund. Higher expenses reduce returns to investors. The use of the Fund’s expense structure would have lowered the performance results. The Fund’s results in the future also may be different because the other accounts are not subject to certain investment limitations, diversification requirements and other restrictions imposed on mutual funds under applicable U.S. securities and tax laws that, if applicable, could have adversely affected the performance of the other accounts. In addition, the securities held by the Fund will not be identical to the securities held by the other accounts.

The performance of the other accounts is also compared to the performance of an appropriate broad-based securities benchmark index. These indexes are unmanaged and are not subject to fees and expenses typically associated with managed funds, including the Fund. Investors cannot invest directly in any broad-based securities index.
