Fees and Expenses of the Fund

This table describes the fees and expenses you may pay if you buy and hold shares of the Multi-Disciplinary Income Fund.

Fee Table⁽¹⁾



SHAREHOLDER FEES (fees paid directly from your investment)	No Load Class
Redemption Fee (as a percentage of amount redeemed on shares held for less than 30 days, if applicable)	2.00%



ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment)		No Load Class
Management Fees⁽¹⁾		1.25%
Distribution (Rule 12b-1) Fees		None
Other Expenses		0.79%
Shareholder Servicing Fees	0.25%
Other Operating Expenses	0.54%
Acquired Fund Fees and Expenses⁽²⁾		0.28%
Total Annual Fund Operating Expenses		2.32%
Fee Waiver and/or Expense Reimbursements⁽³⁾		-0.55%
Total Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursements		1.77%


⁽¹⁾	This table and the example below reflect the aggregate expenses of the Multi-Disciplinary Income Fund and the Multi-Disciplinary Income Portfolio. The management fees paid by the Multi-Disciplinary Income Fund reflect the proportionate share of fees allocated to the Multi-Disciplinary Income Fund from the Multi-Disciplinary Income Portfolio.


⁽²⁾	Total Annual Fund Operating Expenses do not correlate to the ratio of operating expenses to average net assets before expense reimbursement found in the “Financial Highlights” section of this Prospectus, which reflects the Multi-Disciplinary Income Fund’s operating expenses and does not include acquired fund fees and expenses (“AFFE”).

⁽³⁾

Horizon Kinetics Asset Management LLC, the investment adviser to the Multi-Disciplinary Income Portfolio of the Kinetics Portfolio Trust (the “Investment Adviser”), has agreed to waive management fees and reimburse Fund expenses so that Total Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursements do not exceed 1.49%, excluding AFFE and interest expense on securities sold short. These waivers and reimbursements are in effect until May 1, 2021, and may not be terminated without the approval of the Board.

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



	1 Year	3 Years	5 Years	10 Years
No Load Class	$180	$672	$1,190	$2,614

Portfolio Turnover. The Multi-Disciplinary Income Portfolio 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 annual fund operating expenses or in the Example, affect the Multi-Disciplinary Income Portfolio’s, and therefore the Multi-Disciplinary Income Fund’s, performance. During the most recent fiscal year, the Multi-Disciplinary Income Portfolio’s portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategy

The Multi-Disciplinary Income Fund is a diversified fund that invests all of its investable assets in the Multi-Disciplinary Income Portfolio, a series of Kinetics Portfolios Trust. “Total Return” sought by the Multi-Disciplinary Income Portfolio consists of income earned on the Multi-Disciplinary Income Portfolio’s investments, plus capital appreciation. The Multi-Disciplinary Income Portfolio utilizes a two-part investment strategy, which includes fixed-income components, including fixed-income exchange-traded funds (“ETFs”), and derivatives components. Under normal circumstances, the Multi-Disciplinary Income Portfolio will invest at least 65% of its net assets in fixed-income securities, derivatives and cash or cash equivalents committed as collateral for written option contracts.

There is no limit on the amount of assets the Multi-Disciplinary Income Portfolio may invest in fixed-income securities. For purposes of this Prospectus, fixed-income securities include debt securities issued or guaranteed by the U.S. government or by an agency or instrumentality of the U.S. government, corporate bonds and debentures, convertible debt securities, and debt securities of foreign issuers, including emerging markets issuers. Corporate bonds held by the Multi-Disciplinary Income Portfolio generally are senior secured or senior unsecured, are of investment grade quality, and have durations of 0-5 years. However, there is no limit as to the maturities or credit ratings associated with such bonds. The Multi-Disciplinary Income Portfolio may invest up to 100% of its assets in debt securities that are rated below investment grade (“junk” bonds) and up to 5% of its total assets in defaulted junk bonds. The Multi-Disciplinary Income Portfolio may also invest up to 40% of its total assets at the time of purchase in debt securities of emerging market countries. The Multi-Disciplinary Income Portfolio utilizes a proprietary credit spread/relative value model to select positions and a portfolio construction and investment process that relies on value identification and diversification.

The Multi-Disciplinary Income Portfolio may invest up to 100% of its total assets in selling equity put options. The Multi-Disciplinary Income Portfolio may also invest in U.S. Treasury note futures; selling or buying equity calls, bond calls, and bond put options; and credit default swaps, as well as other derivatives, to manage risk or to enhance return. The Multi-Disciplinary Income Portfolio may also buy puts on specific underlying equity securities that are traded on a national securities exchange. The Multi-Disciplinary Income Portfolio will not invest more than 15% of its net assets

in instruments that are not deemed liquid. In connection with the Multi-Disciplinary Income Portfolio’s positions in derivatives, the Multi-Disciplinary Income Portfolio will segregate liquid assets or will otherwise cover its position in accordance with applicable U.S. Securities and Exchange Commission (“SEC”) requirements.

The Investment Adviser uses a bottom-up approach in managing the Multi-Disciplinary Income Fund, which means that the focus is on the analysis of individual securities. By engaging in quantitative and qualitative analysis of individual securities, the Investment Adviser examines a company’s current valuation and earning potential and assesses the company’s competitive positioning. The bonds purchased in the Multi-Disciplinary Income Portfolio are selected from the same universe of companies that the Investment Adviser uses for equity investments. All of the same characteristics apply, however, in the Multi-Disciplinary Income Portfolio option premiums are also considered. Additionally, the Multi-Disciplinary Income Portfolio may participate in securities lending arrangements up to 33-1/3% of the securities in its portfolio with brokers, dealers, and financial institutions (but not individuals) in order to increase the return on its portfolio.

The Investment Adviser may sell a security due to changes in credit characteristics or outlook, as well as changes in portfolio strategy or cash flow needs. A security may also be sold and replaced with one that presents a better value or risk/reward profile. The Investment Adviser may actively trade Multi-Disciplinary Income Portfolio securities.

The Multi-Disciplinary Income Portfolio may maintain during a temporary period, which could be for a short period or a longer period lasting several years or more, of abnormal conditions, a significant portion of its total assets in cash and securities, generally considered to be cash and cash equivalents, including, but not limited to: high quality, U.S. short-term debt securities and money market instruments. The Investment Adviser will invest in such short-term cash positions to the extent that the Investment Adviser is unable to find sufficient investments meeting its criteria and when the Investment Adviser believes the purchase of additional equity securities would not further the investment objective of the Multi-Disciplinary Income Portfolio during such periods of time. Additionally, to respond to adverse market, economic, political or other conditions, which may persist for short or long periods of time, the Multi-Disciplinary Income Portfolio may invest up to 100% of its assets in the types of high quality, U.S. short-term debt securities and money market instruments described above.

If the market advances during periods when the Multi-Disciplinary Income Portfolio is holding a large cash position, the Portfolio may not participate as much as it would have if it had been more fully invested in securities. In the aforementioned temporary defensive periods, the Investment Adviser believes that an additional amount of liquidity in the Multi-Disciplinary Income Portfolio is desirable both to meet operating requirements and to take advantage of new investment opportunities. When the Multi-Disciplinary Income Portfolio holds a significant portion of assets in cash and cash equivalents, it may not meet its investment objective.

Principal Investment Risks

The Multi-Disciplinary Income Portfolio’s investments, including common stocks, have inherent risks that could cause you to lose money. The principal risks of investing in the Multi-Disciplinary Income Fund, and indirectly the Multi-Disciplinary Income Portfolio, are listed below and could adversely affect the net asset value (“NAV”), total return and the value of the Multi-Disciplinary Income Fund, Multi-Disciplinary Income Portfolio and your investment. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a principal risk of investing in the Multi-Disciplinary Income Fund, and indirectly the Multi-Disciplinary Income Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.


ª	Below Investment Grade Debt Securities Risks: Generally, below investment grade debt securities, i.e., junk bonds, are subject to greater credit risk, price volatility and risk of loss than investment grade securities. Junk bonds are considered to be speculative in nature.


ª	Convertible Securities Risks: Convertible securities are subject to the risks affecting both equity and fixed income securities, including market, credit, liquidity and interest rate risk.

Credit Default Swap Agreement Risks: The Fund may enter into credit default swap agreements as a “buyer” or “seller” of credit protection on liquid credit indices. In instances where the Fund is a protection seller (receives a periodic fee over the life of the contract in return for the obligation to compensate the protection buyer for loss), the Fund will assume the risks associated with credit deterioration (spread widening) as well as default risk. In the event of default, the Fund is obligated to pay the buyer of credit protection the notional value of the swap less the recovery rate on the reference asset.


ª	Credit/Default Risk: The risk that an issuer or guarantor of fixed-income securities held by the Multi-Disciplinary Income Portfolio (which may have low credit ratings), or the counterparty in a derivative investment, may default on its obligation to pay interest and repay principal.

Derivatives Risks: The Multi-Disciplinary Income Portfolio’s investments in futures, options and swaps and other derivative instruments may result in loss. Derivative instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Multi-Disciplinary Income Portfolio. To the extent the Multi-Disciplinary Income Portfolio segregates assets to cover derivatives positions, the Multi-Disciplinary Income Portfolio may impair its ability to meet current obligations, to honor requests for redemption and to manage the Multi-Disciplinary Income Portfolio properly in a manner consistent with its stated investment objective.

Emerging Markets Risks: The risk that the securities markets of emerging countries are less liquid, are especially subject to greater price volatility, have smaller market capitalizations, have less government regulation and are not subject to as extensive and frequent accounting, financial and other reporting requirements as the securities markets of more developed countries as have historically been the case.

Exchange-Traded Funds (ETFs) Risks: ETFs are registered investment companies whose shares are listed and traded on U.S. stock exchanges or otherwise traded in the over-the-counter market. In general, passively-managed ETFs seek to track a specified securities index or a basket of securities that an “index provider,” such as Standard & Poor’s, selects as representative of a market, market segment or industry sector. A passively-managed ETF is designed so that its performance will correspond closely with that of the index it tracks. A leveraged ETF will engage in transactions and purchase instruments that give rise to forms of leverage, including, among others, the use of reverse repurchase agreements and other borrowings, the investment of collateral from loans of portfolio securities, the use of when issued, delayed-delivery or forward commitment transactions or short sales. To the extent a fund invests in ETFs that achieve leveraged exposure to their underlying indexes through the use of derivative instruments, the fund will indirectly be subject to leveraging risk. As a shareholder in an ETF, the Multi-Disciplinary Income Portfolio will bear its pro rata portion of an ETF’s expenses, including advisory fees, in addition to its own expenses.

Foreign Securities Risks: The Multi-Disciplinary Income Portfolio may invest directly in foreign debt securities or in U.S. dollar-denominated foreign debt securities through ADRs, GDRs and IDRs. Foreign securities can carry higher returns but involve more risks than those associated with U.S. investments. Additional risks associated with investment in foreign debt securities include currency fluctuations, political and economic instability, differences in financial reporting standards and less stringent regulation of securities markets.

Interest Rate Risk: The risk that when interest rates increase, fixed-income securities held by the Multi-Disciplinary Income Portfolio will decline in value. Long-term fixed-income securities will normally have more price volatility because of this risk than short-term fixed-income securities. It is likely there will be less governmental action in the near future to maintain low interest rates. The negative impact on fixed income securities from the resulting rate increases for that and other reasons could be swift and significant. The risks associated with changing interest rates may have unpredictable effects on the markets and the Multi-Disciplinary Income Portfolio's investments

Leveraging Risks: Investments in derivative instruments may give rise to a form of leverage. The Investment Adviser may engage in speculative transactions, which involve substantial risk and leverage. The use of leverage by the Investment Adviser may increase the volatility of the Multi-Disciplinary Income Portfolio. These leveraged instruments may result in losses to the Multi-Disciplinary Income Portfolio or may adversely affect the Multi-Disciplinary Income Portfolio’s NAV or total return, because instruments that contain leverage are more sensitive

to changes in interest rates. The Multi-Disciplinary Income Portfolio may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Liquidity Risks: The Multi-Disciplinary Income Portfolio’s investments in the securities of small and medium capitalization companies and in non-investment grade fixed-income securities makes the Multi-Disciplinary Income Portfolio especially susceptible to the risk that during certain periods the liquidity of certain issuers or industries, or all securities within particular investment categories, will decrease or disappear suddenly and without warning as a result of adverse market or political events, or adverse investor perceptions. Natural disasters, public health emergencies (including epidemics and pandemics), terrorism and other global unforeseeable events may lead to instability in world economies and markets, market volatility and may have adverse long-term effects.


ª	Management Risks: There is no guarantee that the Multi-Disciplinary Income Fund will meet its investment objective. The Investment Adviser does not guarantee the performance of the Multi-Disciplinary Income Fund, nor can it assure you that the market value of your investment will not decline.

Option Transaction Risks: Purchasing and writing put and call options are highly specialized activities and entail greater than ordinary investment risks. The successful use of options depends in part on the ability of the Investment Adviser to manage future price fluctuations and the degree of correlation between the options and securities (or currency) markets. By writing put options on equity securities, the Multi-Disciplinary Income Portfolio gives up the opportunity to benefit from potential increases in the value of the common stocks above the strike prices of the written put options, but continues to bear the risk of declines in the value of its common stock portfolio. The Multi-Disciplinary Income Portfolio will receive a premium from writing a covered call option that it retains whether or not the option is exercised. The premium received from the written options may not be sufficient to offset any losses sustained from the volatility of the underlying equity securities over time.

Sector Concentration Risk: Although the Multi-Disciplinary Income Portfolio will not concentrate its investments in any industries, the Multi-Disciplinary Income Portfolio may, at certain times, have concentrations in one or more sectors which may cause the Portfolio to be more sensitive to economic changes or events occurring in those sectors. As of December 31, 2019, the Portfolio had 17.4% invested in the Manufacturing sector.


ª	Security Selection Risks: The Multi-Disciplinary Income Portfolio securities selected by the Investment Adviser may decline in value or not increase in value when the stock market in general is rising and may fail to meet the Multi-Disciplinary Income Portfolio’s, and therefore the Multi-Disciplinary Income Fund’s, investment objective.

Who may want to invest?

The Multi-Disciplinary Income Fund may be appropriate for investors who:


ª	wish to diversify their portfolios;


ª	wish to generate income and capital;


ª	wish to invest for the long-term; and


ª	are comfortable with the risks described herein.

Performance

The bar chart and table shown below illustrate the variability of the Multi-Disciplinary Income Fund’s returns. The bar chart indicates the risks of investing in the Multi-Disciplinary Income Fund by showing the changes in the Multi-Disciplinary Income Fund’s performance from year to year (on a calendar year basis).
