Investment Objective

The Fund’s investment objective is to seek long-term capital appreciation.

Fees and Expenses of the Fund

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

Shareholder Fees (Fees paid directly from your investment)

None.

Annual Fund Operating Expenses (Expenses that you pay each year as a percentage of the value of your investment)


	Share Classes
	I	N
Management Fees	0.80%	0.80%
Distribution and/or Service (12b-1) Fees	N/A	0.25%
Other Expenses¹	5.40%	5.40%
Total Annual Fund Operating Expenses	6.20%	6.45%
Fee Waiver and/or Expense Reimbursement²	5.15%	5.40%
Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement²	1.05%	1.05%

¹	Other Expenses are based on estimates for the current fiscal year.

The Fund’s investment advisor has agreed to waive fees and/or reimburse expenses to limit the Fund’s total annual operating expenses (excluding interest, brokerage, extraordinary expenses and acquired fund fees and expenses, if any) to 1.05% of average daily net assets. This contractual fee waiver/expense reimbursement will remain in place through March 1, 2019 and before that date, the investment advisor may not terminate this arrangement without approval of the Board of Directors.

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.

This example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all 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. The cost of investing in the Fund reflects the net expenses of the Fund that result from the contractual expense limitation in the first year only. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:


Share Classes	1 Year	3 Years
I	$107	$1,138
N	$107	$1,175

Portfolio Turnover

The Fund pays transaction costs 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 Fund’s performance. Because the Fund has not yet commenced operations, no portfolio turnover figures are available.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of the value of its net assets, plus any borrowings for investment purposes, in publicly traded equity securities of businesses that the portfolio managers believe are benefitting from or have the potential to benefit from advances in the use of artificial intelligence. Artificial intelligence refers to the development or use by a business of computer systems that perform tasks previously requiring human intelligence such as decision-making or audio or visual identification or perception. The Fund invests primarily in issuers that are characterized as “growth companies” according to criteria established by the portfolio managers, which may include attributes such as an expected growth cycle, accelerating earnings or cash flow, and general growth of a business sector. Bottom-up fundamental research that focuses on the individual attributes of a company, such as its financial characteristics, is used to identify these companies. If the Fund changes this investment policy, it will notify shareholders in writing at least 60 days in advance of the change. Equity securities include common and preferred stock; rights or warrants to purchase common or preferred stock; securities convertible into common or preferred stock such as convertible preferred stock, bonds or debentures; American Depository Receipts (ADRs); and other securities with equity characteristics.

The Fund typically invests in companies in information technology, consumer discretionary, industrial and health care sectors with market capitalizations of at least $300 million at the time of acquisition. The Fund typically invests in a portfolio of 25 to 60 companies. The portfolio managers use both qualitative and quantitative screening criteria to supplement the fundamental research. The portfolio managers’ qualitative

screening focuses on those companies that they believe have the potential to grow or otherwise materially benefit partly as a result of their development or use of artificial intelligence in analysis, forecasting, efficiency, automation, consistency and scale.

Portfolio securities may be sold for a number of reasons, including when a company fails to meet expectations or when the portfolio managers believe that (i) there has been a deterioration in the underlying fundamentals of a company, (ii) the intermediate- and long-term prospects for a company are poor or the original thesis was flawed or has been damaged, (iii) another security may offer a better investment opportunity, (iv) an individual security has reached its sell target or the investment therein has been exhausted, or (v) the portfolio should be rebalanced for diversification or portfolio weighting purposes.

Principal Risks

Since the Fund holds securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up. You can lose money by investing in the Fund.

The principal risks affecting the Fund that can cause a decline in value are:

•

equity risk: the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods as a result of changes in a company’s financial condition and in overall market, economic and political conditions.

•

foreign currency risk: the risk that foreign currencies will decline in value relative to the U.S. dollar and affect the Fund’s investments denominated in foreign currencies or the Fund’s investments in foreign currencies or in securities that trade in and receive revenues in, or in derivatives that provide exposure to, foreign currencies.

•

foreign investing risk: the risk that Fund share prices will fluctuate with market conditions, currency exchange rates and the economic and political climates of the foreign countries in which the Fund invests or has exposure.

•

globalization risk: the risk that the growing inter-relationship of global economies and financial markets has magnified the effect of conditions in one country or region on issuers of securities in a different country or region.

•

sector concentration risk: the risk that the Fund may be susceptible to the impact of market, economic, regulatory,

and other factors affecting the technology sector because of its concentrated investments in companies expected to benefit from the rising influence of artificial intelligence. At times of such impact, the value of the Fund may fluctuate more widely than it would for a fund that invests more broadly across varying sectors.

•

investment style risk: the risk that the particular style or set of styles that the investment advisor primarily uses may be out of favor or may not produce the best results over short or longer time periods and may increase the volatility of the Fund’s share price.

•

issuer risk: the risk that the value of a security may decline for reasons directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services.

•

liquidity risk: the risk that there may be no willing buyer of the Fund’s portfolio securities and the Fund may have to sell those securities at a lower price or may not be able to sell the securities at all, each of which would have a negative effect on performance.

•

market risk: the risk that returns from the securities in which the Fund invests may underperform returns from the general securities markets or other types of securities.

•

non-diversification risk: the risk that the Fund may be more susceptible to any single economic, political or regulatory event than a diversified fund because a higher percentage of the Fund’s assets may be invested in the securities of a limited number of issuers.

•

portfolio management risk: the risk that the Fund’s investment strategy may fail to produce the intended results.

•

price volatility risk: the risk that the value of the Fund’s investment portfolio will change as the prices of its investments go up or down.

•

securities selection risk: the risk that the securities held by the Fund may underperform those held by other funds investing in the same asset class or benchmarks that are representative of the asset class because of the portfolio managers’ choice of securities.

•

small- and mid-capitalization company risk: the risk that small- and mid-capitalization companies may have more volatile stock performance than large-capitalization companies and are more likely to experience business failures, which may increase the risk of loss to the Fund.

•

cybersecurity risk: the risk that information and technology systems relied upon by the Fund, the investment advisor, the Fund’s service providers and/or the issuers of securities in which the Fund invests may be vulnerable to

damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons or security breaches.

Please see “Principal Risks of the Fund” for a more detailed description of the risks of investing in the Fund.

Your investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency entity or person.

Other Important Information Regarding Fund Shares

For more information about purchase and sale of Fund shares, tax information, and payments to broker-dealers and other financial intermediaries, please turn to the “Summary of Other Important Information Regarding Fund Shares” at page 4 of this Prospectus.

Purchase and Sale of Fund Shares

You may purchase or redeem Fund shares on any business day (normally any day the New York Stock Exchange is open). Purchase and redemption orders for Fund shares are processed at the net asset value next calculated after an order is received by the Fund.

You may conduct transactions by mail (TCW Funds, Inc. c/o U.S. Bancorp Fund, Services, LLC, P.O. Box 701, Milwaukee, WI 53201-0701), or by telephone at 1-800-248-4486. Redemptions by telephone are only permitted upon previously receiving appropriate authorization. You may also purchase, exchange or redeem Fund shares through your dealer or financial advisor.

Purchase Minimums for All Share Classes


Type of Account	Minimum Initial Investment			Subsequent Investments
Regular		$	2,000		$	250
Individual/Retirement Account		$	500		$	250

A broker-dealer or other financial intermediary may require a higher minimum initial investment, or may aggregate or combine accounts in order to allow its customers to apply a lower minimum investment.

Tax Information

Dividends and capital gains distributions you receive from the Fund are subject to federal income taxes and may also be subject to state and local taxes, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account. Such tax-deferred arrangements may be taxed later upon withdrawal from those arrangements.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund shares through a broker-dealer or other financial intermediary (such as a bank), the Fund and the Fund’s distributor or its affiliates may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial advisor to recommend the Fund over another investment. Ask your individual financial advisor or visit your financial intermediary’s website for more information.

The Fund is affected by changes in the economy, or in securities and other markets. There is also the possibility that investment decisions TCW Investment Management Company LLC (the “Advisor”) makes with respect to the investments of the Fund will not accomplish what they were designed to achieve or that the investments will have disappointing performance.

Risk is the chance that you will lose money on your investment or that it will not earn as much as you expect. In general, the greater the risk, the more money your investment has the potential to earn for you — and the more you can lose. Because the Fund holds securities with fluctuating market prices, the value of the Fund’s shares will vary as its portfolio securities increase or decrease in value. Therefore, the value of your investment in the Fund could go down as well as up.

The Fund may engage in defensive investing, which is a deliberate, temporary shift in portfolio strategy that may be undertaken when markets start behaving in volatile or unusual ways. The Fund may, for temporary defensive purposes, invest a substantial part of its assets in bonds of U.S. or foreign governments, certificates of deposit, bankers’ acceptances, high-grade commercial paper, repurchase agreements, money market funds and cash. When the Fund has invested defensively in low risk, low return securities, it may not achieve its investment objective. References to minimum credit ratings or quality for securities apply to the time of investment.

Your investment in the Fund is not a bank deposit, and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, entity, or person. You can lose money by investing in the Fund. When you sell your shares of the Fund, they could be worth more or less than what you paid for them.

Your investment may be subject (in varying degrees) to the following risks discussed below. The Fund may be more susceptible to some of the risks than others.

Cybersecurity Risk

Information and technology systems relied upon by the Fund, the Advisor, the Fund’s service providers (including, but not

limited to, Fund accountants, custodians, transfer agents, administrators, distributors and other financial intermediaries) and/or the issuers of securities in which the Fund invests may be vulnerable to damage or interruption from computer viruses, network failures, computer and telecommunication failures, infiltration by unauthorized persons, security breaches, usage errors, power outages and catastrophic events such as fires, tornadoes, floods, hurricanes and earthquakes. Although the Advisor has implemented measures to manage risks relating to these types of events, if these systems are compromised, become inoperable for extended periods of time or cease to function properly, significant investment may be required to fix or replace them. The failure of these systems and/or of disaster recovery plans could cause significant interruptions in the operations of the Fund, the Advisor, the Fund’s service providers and/or issuers of securities in which the Fund invests and may result in a failure to maintain the security, confidentiality or privacy of sensitive data, including personal information relating to investors (and the beneficial owners of investors). Such a failure could also harm the reputation of the Fund, the Advisor, the Fund’s service providers and/or issuers of securities in which the Fund invests, subject such entities and their respective affiliates to legal claims or otherwise affect their business and financial performance.

Equity Risk

Equity securities may include common stock, preferred stock or other securities representing an ownership interest or the right to acquire an ownership interest in an issuer. Equity risk is the risk that stocks and other equity securities generally fluctuate in value more than bonds and may decline in value over short or extended periods. The value of stocks and other equity securities may be affected by changes in an issuer’s financial condition and in overall market, economic and political conditions.

Foreign Currency Risk

Funds that invest in foreign (non-U.S.) securities that trade in, and receive revenues in, foreign (non-U.S.) currencies are subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of

governments, central banks or supranational entities such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the U.S. or abroad. As a result, the Fund’s investments in non-U.S. dollar-denominated securities may reduce the returns of the Fund.

Foreign Investing Risk

Investments in foreign securities may involve greater risks than investing in domestic securities.

As compared to U.S. companies, foreign issuers generally disclose less financial and other information publicly and are subject to less stringent and less uniform accounting, auditing and financial reporting standards. Foreign countries typically impose less thorough regulations on brokers, dealers, stock exchanges, corporate insiders and listed companies than does the U.S., and foreign securities markets may be less liquid and more volatile than U.S. markets. Investments in foreign securities involve higher costs than investments in U.S. securities, including higher transaction and custody costs as well as additional taxes imposed by foreign governments. In addition, security trading practices abroad may offer less protection to investors such as the Fund. Political or social instability, civil unrest, acts of terrorism and regional economic volatility are other potential risks that could impact an investment in a foreign security. Settlement of transactions in some foreign markets may be delayed or may be less frequent than in the U.S., which could affect the liquidity of the Fund’s portfolio.

The European financial markets have continued to experience volatility because of concerns about economic downturns and about high and rising government debt levels of several countries in the European Union and Europe generally. These events have adversely affected the exchange rate of the Euro and the European securities markets, and may spread to other countries in Europe, including countries that do not use the Euro. These events may affect the value and liquidity of certain of the Fund’s investments. Responses to the financial problems by European Union governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences. Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world.

In a public referendum in June 2016, the United Kingdom voted to leave the European Union (a process now commonly referred to as “Brexit”). As a result of and based on the pronouncements of the United Kingdom government, it is probable that negotiations will take place to determine the terms of the United Kingdom’s departure from, and of its new political and economic relationship with, the European Union. This could lead to a period of significant uncertainty and increased volatility in both U.S. and global securities and currency markets. In addition to concerns related to the effect of Brexit, that referendum may inspire similar initiatives in other European Union member countries, producing further risks for global financial markets.

Globalization Risk

The growing inter-relationship of global economies and financial markets has magnified the effect of conditions in one country or region on issuers of securities in a different country or region. In particular, the adoption or prolongation of protectionist trade policies by one or more countries, changes in economic or monetary policy in the United States or abroad, or a slowdown in the United States economy could lead to a decrease in demand for products and reduced flows of capital and income to companies in other countries. Those events might particularly affect companies in emerging and developing market countries.

Investment Style Risk

The particular style or set of styles that the Advisor primarily uses for the Fund may be out of favor or may not produce the best results over short or longer time periods and may increase the volatility of the Fund’s share price.

Issuer Risk

The value of securities held by the Fund may decline for a number of reasons directly related to an issuer, such as changes in the financial condition of the issuer, management performance, financial leverage and reduced demand for the issuer’s goods or services. The amount of dividends paid with respect to equity securities, or the ability of an issuer to make payments in connection with debt securities, may decline for reasons that relate to the issuer, such as changes in an issuer’s financial condition or a decision by the issuer to pay a lower dividend, or for reasons that relate to the broader financial system. In addition, there may be limited public information available for the Advisor to evaluate foreign issuers.

Liquidity Risk

The Fund’s investments in illiquid securities may reduce the returns of the Fund because it may not be able to sell the illiquid securities at an advantageous time or price. Investments in high yield securities, foreign securities, derivatives or other securities with substantial market and/or credit risk tend to have the greatest exposure to liquidity risk. Certain investments in private placements and Rule 144A securities may be considered illiquid investments.

The securities of many of the companies with small- and mid-capitalizations may have less “float” (the number of shares that normally trade) and less interest in the market and therefore are subject to liquidity risk.

Market Risk

Various market risks can affect the price or liquidity of an issuer’s securities in which the Fund may invest. Returns from the securities in which the Fund invests may underperform returns from the various general securities markets or different asset classes. Different types of securities tend to go through cycles of outperformance and underperformance in comparison to the general securities markets. Adverse events occurring with respect to an issuer’s performance or financial position can depress the value of the issuer’s securities. The liquidity in a market for a particular security will affect its value and may be affected by factors relating to the issuer, as well as the depth of the market for that security. Other market risks that can affect value include a market’s current attitudes about types of securities, market reactions to political or economic events, including litigation, and tax and regulatory effects (including lack of adequate regulations for a market or particular type of instrument).

Instability in the financial markets has led the U.S. Government to take a number of unprecedented actions designed to support certain financial institutions and segments of the financial markets that have experienced extreme volatility, and in some cases a lack of liquidity. Federal, state, and other governments, their regulatory agencies, or self-regulatory organizations may take actions that affect the regulation of the securities in which the Fund invests or the issuers of such securities in ways that are unforeseeable. Legislation or regulation may also change the way in which the Fund is regulated. Such legislation or regulation could limit or preclude the Fund’s ability to achieve its investment objective.

Non-Diversification Risk

The Fund is organized as a non-diversified fund under the 1940 Act, and is not subject to the general limitation that with

respect to 75% of a fund’s total assets, it may not invest more than 5% of its total assets in any particular issuer or hold more than 10% of the outstanding voting securities of any particular issuer. The Fund, however, remains subject to a diversification requirement under applicable tax laws that is less strict than under the 1940 Act. Because a relatively higher percentage of the Fund’s assets may be invested in the securities of a limited number of issuers, the Fund may be more susceptible to any single economic, political or regulatory event than a diversified fund.

Portfolio Management Risk

Portfolio management risk is the risk that an investment strategy may fail to produce the intended results. There can be no assurance that the Fund will achieve its investment objective. The Advisor’s judgments about the attractiveness, value and potential appreciation of particular securities may prove to be incorrect and may not anticipate actual market movements or the impact of economic conditions generally. No matter how well a portfolio manager evaluates market conditions, the securities a portfolio manager chooses may fail to produce the intended result, and you could lose money on your investment in the Fund.

Price Volatility Risk

The value of the Fund’s investment portfolio will change as the prices of its investments go up or down. Although stocks offer the potential for greater long-term growth than most debt securities, stocks generally have higher short-term volatility. The Fund invests primarily in the equity securities of small- and/or mid-capitalization companies, which are subject to greater price volatility than other mutual funds.

Different parts of the market and different types of securities can react differently to developments. Issuer, political or economic developments can affect a single issuer, issuers within an industry or economic sector or geographic region or market as a whole.

Prices of most securities tend to be more volatile in the short-term. Therefore, if you trade frequently or redeem in the short-term, you are more likely to incur a loss than an investor who holds investments for the longer-term. The fewer the number of issuers in which the Fund invests, the greater the potential volatility of its portfolio.

Sector Concentration Risk

The Fund likely will focus on technology companies or companies that depend substantially on artificial intelligence

technology. This means that the Fund will be susceptible to the impact of market, economic, regulatory, and other factors affecting the technology sector because of its concentrated investments in companies that benefit from the rising influence of artificial intelligence. At times of such impact, the value of the Fund may fluctuate more widely than it would for a fund that invests more broadly across varying sectors.

Securities Selection Risk

The specific securities held in the Fund’s investment portfolio may underperform those held by other funds in the same asset class or benchmarks that are representative of the asset class because of a portfolio manager’s choice of securities.

Small- and Mid-Capitalization Company Risk

The Fund may invest a portion of its assets in the equity securities of companies with small- and mid-capitalizations and may be subject to certain risks associated with such companies. Companies with small- and mid-capitalizations often have narrower markets, fewer products or services to offer and more limited managerial and financial resources than do larger, more established companies. As a result, small- and mid-capitalization companies may have more volatile stock performance than large-capitalization companies and are more likely to experience business failures, which may increase the risk of loss to the Fund.

Additional Risks

Financial Services Sector Risk

The financial services sector is subject to extensive government regulations, which may change frequently. In addition, the profitability of businesses in the financial services sector depends heavily on the availability and cost of money and may fluctuate significantly in response to changes in interest rates, as well as changes in general economic conditions. The financial services sector is exposed to risks that may impact the value of investments in the sector more severely than investments outside the sector. Businesses in the financial services sector often operate with substantial financial leverage.

Securities Lending Risk

The Fund may lend portfolio securities with a value equal to up to 25% of its total assets, including collateral received for securities lent. If the Fund lends securities, there is a risk that the securities will not be available to the Fund on a timely basis, and the Fund, therefore, may lose the opportunity to sell the securities at a desirable price. In addition, as with other extensions of credit, there is the risk of possible delay in receiving additional collateral or in the recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. Also, there is the risk that the value of the investment of the collateral could decline causing the Fund to lose money.

Valuation Risk

Portfolio securities may be valued using techniques other than market quotations in circumstances described under “Calculation of NAV.” This is more likely for certain types of derivatives such as swaps. The value established for a portfolio security may be different than the value that would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio securities that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. The Fund may from time to time purchase an “odd lot” or smaller quantity of a security that trades at a discount to the price of a “round lot” or larger quantity preferred for trading by institutional investors. If the Fund is able to combine an odd lot purchase with an existing holding to make a round lot or larger position in the security, the Fund may be able to immediately increase the value of the security purchased, in accordance with its valuation procedures. There is no assurance that the Fund could sell a portfolio security for the value established for it at any time and it is possible that the Fund would incur a loss because a portfolio security is sold at a discount to its established value.

Investment Advisor

The Fund’s investment advisor is TCW Investment Management Company LLC and is headquartered at 865 South Figueroa Street, Suite 1800, Los Angeles, California 90017. The Advisor was organized in 1987 as a wholly-owned subsidiary of The TCW Group, Inc. (“TCW”). The Advisor is registered with the Securities and Exchange Commission (the “SEC”) as an investment advisor under the Investment Advisers Act of 1940, as amended.

As of June 30, 2017, the Advisor and its affiliated companies, which provide a variety of investment management and investment advisory services, had approximately $196.9 billion in assets under management or committed to management.

TCW Artificial Intelligence Equity Fund
Jeffrey W. Lin, CFA		Senior Vice President, the Advisor and TCW, LLC.

Thomas Lee		Senior Vice President, the Advisor and TCW, LLC (since 2014). Previously, Senior Research Analyst at Empire Capital (2013 – 2014) and Research Analyst at Goldman Sachs (2007 – 2012).

Advisory Agreement

TCW Funds, Inc. (the “Corporation”), on behalf of the Fund, and the Advisor have entered into an Investment Advisory

and Management Agreement, as amended (the “Advisory Agreement”), under the terms of which the Fund has employed the Advisor to, subject to the direction and supervision of the Board of Directors of the Corporation (the “Board of Directors”), provide investment advisory and management services, including, among others, managing the investment of the assets of the Fund, placing orders for the purchase or sale of portfolio securities for the Fund, administering the day-to-day operations of the Fund, furnishing to the Corporation office space and all necessary office facilities, supplies and equipment, and arranging for officers or employees of the Advisor to serve, without compensation from the Corporation, as officers, directors or employees of the Corporation.

Under the Advisory Agreement, the Fund pays to the Advisor, as compensation for the services rendered, facilities furnished, and expenses paid by it, the following fees:


Fund	Annual Management Fee (As Percent of Average Net Asset Value)
TCW Artificial Intelligence Equity Fund		0.80	%

In addition to the contractual expense limitations listed below that apply to the Fund, the Advisor has agreed to reduce its investment management fee or to pay the operating expenses of the Fund to limit the Fund’s operating expenses to an amount not to exceed the previous month’s expense ratio average for comparable funds as calculated by Lipper Inc. This expense limitation is voluntary and terminable by either the Advisor or the Board of Directors on six months’ prior notice. This voluntary limitation and the contractual fee waiver and/or expense reimbursement excludes interest, brokerage, extraordinary expenses, and acquired fund fees and expenses, if any.


TCW Artificial Intelligence Equity Fund
I Class Shares		1.05%
N Class Shares		1.05%

A discussion regarding the basis for the Board of Directors’ approval of the Advisory Agreement for the Fund will be contained in the Corporation’s annual report to shareholders for the fiscal year ending October 31, 2017.

Payments by the Advisor

The Advisor pays certain costs of marketing the Fund from legitimate profits from its management fees and other resources available to it. The Advisor may also share with financial intermediaries (as defined below in the “Your Investment — Account Policies and Services — Calculation of NAV” section) certain marketing expenses or pay for the opportunity to distribute the Fund, sponsor informational meetings, seminars, client awareness events, support for marketing materials, or business building programs. The Advisor or its affiliates may pay amounts from their own resources to third parties, including brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries for providing record keeping, sub-accounting, transaction processing and other administrative services. These payments, which may be substantial, are in addition to any fees that may be paid by the Fund for these types of or other services.

The amount of these payments is determined from time to time by the Advisor and may differ among such financial intermediaries. Such payments may provide incentives for such parties to make shares of the Fund available to its customers, and may allow the Fund greater access to such parties and their customers than would be the case if no payments were paid. Such access advantages include, but are not limited to, placement of the Fund on a list of mutual funds offered as investment options to the financial intermediary’s customers (sometimes referred to as “Shelf Space”); access to the financial intermediary’s registered representatives; and/or ability to assist in training and educating the financial intermediary’s registered representatives. These payment arrangements will not, however, change the price an investor pays for shares of the Fund or the amount that the Fund receives to invest on behalf of the investor. These payments may create potential conflicts of interests between an investor and a financial intermediary who is recommending a particular mutual fund over other mutual funds. You may wish to consider whether such arrangements exist when evaluating any recommendations to purchase or sell shares of the Fund and you should contact your financial intermediary for details about any payments it may receive from the Fund or from the Advisor. Payments are typically based on a percentage of assets under management or based on the number of customer accounts or a combination thereof.

Multiple Class Structure

The Fund currently offers two classes of shares: Class I shares and Class N shares. Shares of each class of the Fund represent an equal pro rata interest in the Fund and both classes generally have the same voting, liquidation, and other rights. The Class I shares are offered at the current net asset value. The Class N shares are offered at the current net asset value, but are subject to fees imposed under a distribution plan (the “Distribution Plan”) adopted pursuant to Rule 12b-1 under the 1940 Act. Pursuant to the Distribution Plan, the Fund compensates the Fund’s distributor for distribution and related services at a rate equal to 0.25% of the average daily net assets of the Fund attributable to its Class N shares. The fees may be used to pay the Fund’s distributor for distribution services and sales support services provided in connection with Class N shares. The fee may also be used to pay financial intermediaries for the sales support services and related expenses and shareholder servicing fees. The shareholder servicing fees are paid to compensate financial intermediaries for the administration and servicing of shareholder accounts and are not costs which are primarily intended to result in the sale of the Fund’s shares. Because these fees are paid out of the Fund’s Class N assets on an on-going basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. Because the expenses of each class may differ, the performance of each class is expected to differ.

Other Shareholder Servicing Expenses Paid by the Fund

The Fund is authorized to compensate each broker-dealer and other third-party intermediary up to such percentage as approved by the Board of Directors of the assets serviced for the Fund by that intermediary for shareholder services. These services constitute sub-recordkeeping, sub-transfer agent or similar services and are similar in scope to services provided by the transfer agent to the Fund. These expenses paid by the Fund would remain subject to any overall expense limitation applicable to the Fund. These expenses are in addition to any payment of any amounts through the Distribution Plan. This amount may be adjusted, subject to approval by the Board of Directors.

You pay no sales charges to invest in the Fund. Your price for the Fund’s shares is the Fund’s net asset value per share (“NAV”) which is calculated as of the close of trading on the New York Stock Exchange (“NYSE”) (usually 4:00 p.m. Eastern time or the time trading closes on the NYSE, whichever is earlier) every day the exchange is open. In addition to Saturday and Sunday, the NYSE is closed on the days that the following holidays are observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas Day. Shares cannot be purchased by wire transactions on days when banks are closed.

Calculation of NAV

The NAV of each Class of the Fund is determined by adding the value of that Class’s securities, cash and other assets, subtracting all expenses and liabilities attributable to that Class, and then dividing by the total number of shares of that Class issued and outstanding (assets-liabilities/# of shares = NAV).

Your order will be priced at the next NAV calculated after your order is accepted by the Corporation. Orders received by the Fund’s transfer agent from dealers, brokers or other service providers (“financial intermediaries”) after the NAV for the day is determined will receive that same day’s NAV if the orders were received by the financial intermediary from its customers prior to 4:00 p.m. Eastern time (or the time trading closes on the NYSE, whichever is earlier). Your financial intermediary is responsible for transmitting such orders promptly.

The Corporation may at its discretion reject any purchase order for Fund shares.

The Fund discloses its NAV on a daily basis. To obtain the Fund’s NAV, please call (800) FUND TCW or visit the TCW Funds, Inc. website at www.tcw.com.

The Fund’s investments for which market quotations are readily available are valued based on market value. Equity securities, including depository receipts, are valued at the last reported sale price as reported by the stock exchange or pricing service. Securities traded on the NASDAQ Stock Market

(“NASDAQ”) are valued using the official closing prices as reported by NASDAQ. In cases where equity securities are traded on more than one exchange, the securities are valued using the prices from the respective primary exchange of each security. Options on equity securities are valued at the average of the latest bid and ask prices as reported by the stock exchange or pricing service. S&P 500 futures contracts generally are valued at the first sale price after 4:00 p.m. ET on the Chicago Mercantile Exchange. All other futures contracts are valued at the official settlement price of the exchange on which the applicable contract is traded. Changes to market closure times may alter when futures contracts are valued. The daily NAV may not reflect the closing market price for all futures contracts and options held by the Fund because the markets for certain futures contracts and options close shortly after the time the NAV is calculated. Securities traded over-the-counter are valued using prices furnished by independent pricing services or by broker dealers.

Investments initially valued in currencies other than the U.S. dollar are converted to the U.S. dollar using exchange rates obtained from pricing services. As a result, the NAV of the Fund’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of securities traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the NYSE is closed and an investor is not able to purchase, redeem or exchange shares.

The Corporation may use the fair value of a security as determined in accordance with procedures adopted by the Board of Directors if market quotations are unavailable or deemed unreliable or if events occurring after the close of a securities market and before the Corporation values its assets would materially affect net asset value. Such situations are particularly relevant for the Fund that holds securities that trade primarily in overseas markets. A security that is fair valued may be valued at a price higher or lower than actual market quotations or the value determined by other funds using their own fair valuation procedures. Unlike the closing price of a security on an exchange, fair value determinations employ elements of judgment. The fair value assigned to a security may not represent the value that the Fund could obtain if it were to sell the security.

The net asset value of the Fund’s investments in other investment companies will be calculated based upon the net asset value of those investment companies; the offering documents for those investment companies explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing.

Minimums


Type of Account	Minimum Initial Investment			Subsequent Investments
Regular		$	2,000		$	250
Individual/Retirement Account		$	500		$	250

The Corporation may accept investments of smaller amounts under circumstances deemed appropriate. The Corporation reserves the right to change the minimum investment amounts without prior notice. A broker-dealer or other financial intermediary may require a higher minimum initial investment, or may aggregate or combine accounts in order to allow its customers to apply a lower minimum investment. All investments must be in U.S. dollars drawn on domestic banks. The Corporation will not accept money orders, traveler’s checks, bank checks, drafts, cashiers’ checks in amounts less than $10,000 or credit card checks. Third-party checks, except those payable to an existing shareholder, will not be accepted. In addition, the Fund will not accept cash, checks drawn on banks outside the U.S., starter checks, post-dated checks, post-dated on-line checks or any conditional order or payment. If your check does not clear, you will be responsible for any loss the Fund incurs such as a loss resulting from a change in NAV. You will also be charged $25 for every check returned unpaid.

The Fund has adopted an Anti-Money Laundering Compliance Program as required by the United Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT ACT) and appointed an Anti-Money Laundering Officer to help the government fight the funding of terrorism and money laundering activities. Federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. What this means for you is that when you open an account, the Fund’s transfer agent will ask you for your name, address, date of birth, taxpayer identification number and permanent street address. Mailing addresses containing only a P.O. Box will not be accepted. The transfer agent may also ask to see your driver’s license or other identification documents, and may

consult third-party databases to help verify your identity. If the transfer agent is unable to verify your identity or that of another person authorized to act on your behalf, or if it believes it has identified potentially criminal activity, the transfer agent reserves the right to close your account or take any other action it deems reasonable or required by law.

Automatic Investment Plan

Once your account has been opened with the initial minimum investment you may make additional purchases at regular intervals through the Automatic Investment Plan (“AIP”). The AIP provides a convenient method to have monies deducted from your bank account for investment into the Fund, on a monthly, bi-monthly, quarterly or semi-annual basis (if your AIP falls on a weekend or holiday, it will be processed on the following business day). In order to participate in the AIP, each purchase must be in the amount of $100 or more and your financial institution must be a member of the Automated Clearing House (“ACH”) network. If your financial institution rejects your payment, the Fund’s transfer agent will charge a $25 fee to your Fund account. To begin participating in the AIP, please complete the AIP section on the account application or call the Fund’s transfer agent at (800) 248-4486 for additional information. Any request to change or terminate your AIP should be submitted to the transfer agent at least five business days prior to the effective date of the next transaction.

Selling Shares

You may sell shares at any time. Your shares will be sold at the next NAV calculated after your order is accepted by the Fund’s transfer agent or a dealer, broker or other service provider. Any certificates representing Fund shares being sold must be returned with your redemption request. Your order will be processed promptly, and you will generally receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not yet collected payment for the shares you are selling, it may delay sending the proceeds for up to fifteen calendar days from the purchase date or until payment is collected, whichever is earlier.

Shareholders who have an IRA or other retirement plan must indicate on their redemption request whether or not to withhold federal income tax. Redemption requests failing to indicate an election not to have tax withheld will generally be subject to 10% withholding.

Signature Guarantees

Some circumstances require written sell orders, along with signature guarantees. These include:

•

amounts in excess of $100,000

•

amounts of $1,000 or more on accounts whose address has been changed within the last 30 calendar days

•

requests to send the proceeds to a payee, address or a bank account different than what is on our records

•

if ownership is changed on your account

•

written requests to wire redemptions proceeds (if not previously authorized on the account)

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

The Fund and/or the transfer agent reserves the right to waive or require any signature guarantee based on the circumstances relative to the particular situation.

A signature guarantee helps protect against fraud. You can obtain one from most banks, securities dealers, credit unions or savings associations but not from a notary public. Please call (800) 248-4486 to ensure that your signature guarantee will be processed correctly.

Exchanging Shares

You can exchange from Class I or Class N shares of the Fund into the same Class of another TCW Fund offered in a different prospectus, provided that your investment meets the minimum initial investment and any other requirements of the same Class of the other TCW Fund and that the shares of the same Class of the other TCW Fund are eligible for sale in your state of residence. Further information about conversion of shares between classes of the same Fund may be found in the Fund’s SAI. You can request your exchange in writing or by phone. Be sure to read the current prospectus for any fund into which you are exchanging. Any new account established through an exchange will have the same privileges as your original account (as long as they are available).

You may also exchange the shares of the Fund you own for shares of Fidelity Prime Money Market Portfolio, which is an unaffiliated, separately managed, money market mutual fund, or exchange shares of Fidelity Prime Money Market Portfolio for shares of any fund. You should read the Fidelity Prime

Money Market Portfolio prospectus prior to investing in that fund. You can obtain a prospectus for the Fidelity Prime Money Market Portfolio by calling (800) 386-3829 or by visiting our website at www.tcw.com.

Third Party Transactions

You may buy and redeem the Fund’s shares through certain broker-dealers and financial organizations and their authorized intermediaries. If purchases and redemptions of the Fund’s shares are arranged and settlement is made at an investor’s election through a registered broker-dealer, other than the Fund’s distributor, that broker-dealer may, at its discretion, charge a fee for that service.

Account Statements

The Fund investor automatically receives regular account statements. You will also be sent a yearly statement detailing the tax characteristics of any dividends and distributions you have received.

Household Mailings

Each year you are automatically sent an updated prospectus and annual and semi-annual reports for the Fund. You may also receive proxy statements for the Fund. In order to reduce the volume of mail you receive, when possible and unless the Corporation receives contrary instructions, only one copy of these documents will be sent to those addresses shared by two or more accounts. You may write the Corporation at 865 South Figueroa Street, Los Angeles, California 90017 or telephone it at 1-800-386-3829 to request individual copies of documents or to request a single copy of documents if receiving duplicate copies. The Corporation will begin sending a household single or multiple copies, as requested, as soon as practicable after receiving the request.

General Policies

If your non-retirement account in the Fund falls below $2,000 as a result of redemptions and or exchanges for six months or more, the Fund may close your account and send you the proceeds upon 60 days’ written notice.

Unless you decline telephone privileges on your New Account Form, you may be responsible for any fraudulent telephone order as long as the Fund’s transfer agent takes reasonable measures to verify the order. Reasonable measures include a requirement for a caller to provide certain personal identifying information. If an account of the Fund has more than one owner or authorized person, the Fund will accept telephone instructions from any one owner or authorized person.

The Fund also reserves the right to make a “redemption in kind” — payment in portfolio securities rather than cash — if the amount you are redeeming in any 90-day period is large enough to affect Fund operations (for example, if it equals more than $250,000 or represents more than 1% of the Fund’s assets). Securities used to make an in-kind redemption would normally be a representative basket of securities, subject to reasonable minimum quantities to allow possible later sale by the shareholder. If your shares are redeemed in kind you will incur transaction costs upon disposition of the securities received in the distribution.

Any undeliverable dividend checks or dividend checks that remain uncashed for six months will be cancelled and will be reinvested in the Fund at the per share net asset value determined as of the date of cancellation.

After the transfer agent has received the redemption request and all proper documents, payment for shares tendered will generally be made within (i) one to three business days for redemptions made by wire, and (ii) three to five business days for ACH redemptions. Redemption payments by check will generally be issued on the business day following the redemption date; however, actual receipt of the check by the redeeming investor will be subject to postal delivery schedules and timing.

Under normal circumstances, the Fund typically expects to meet redemptions with positive cash flows. When that cash is not available, the Fund seeks to maintain its portfolio weightings by selling a cross section of the Fund’s holdings to meet redemptions, while also factoring in trading costs. Under certain circumstances, including under stressed market conditions, there are additional tools that the Fund may use in order to meet redemptions, including advancing the settlement of market trades with counterparties to match investor redemption payments or delaying settlement of an investor’s transaction to match trade settlement, within regulatory requirements. Under unusual circumstances, the Fund may also borrow money (subject to certain regulatory conditions) through a bank line of credit, including a joint committed credit facility, or inter-fund borrowing from affiliated mutual funds, in order to meet redemption requests. Payment may be delayed or made partly in-kind with marketable securities under unusual circumstances, as specified in the 1940 Act.

Trading Limits

The Fund is not intended to serve as vehicles for frequent trading activity because such trading may disrupt management of the Fund. In addition, such trading activity can

increase expenses as a result of increased trading and transaction costs, forced and unplanned portfolio turnover, lost opportunity costs, and large asset swings that decrease the Fund’s ability to provide maximum investment returns to all shareholders. In addition, certain trading activity that attempts to take advantage of inefficiencies in the valuation of the Fund’s securities holdings may dilute the interests of the remaining shareholders. This in turn can have an adverse effect on the Fund’s performance.

Accordingly, the Board of Directors has adopted the following policies and procedures with respect to frequent purchases and redemptions of Fund shares by shareholders. The Fund reserves the right to refuse any purchase or exchange request that could adversely affect the Fund or its operations, including those from any individual or group who, in the Fund’s view, is likely to engage in excessive trading. If a purchase or exchange order with respect to the Fund is rejected, the potential investor will not benefit from any subsequent increase in the net asset value of the Fund.

Future purchases into the Fund may be barred if a shareholder effects a round trip in shares of the Fund (meaning exchanges or redemptions following a purchase) in excess of certain de minimis limits within a 30-day period.

Exceptions to these trading limits may be made only upon approval of the Corporation’s Chief Compliance Officer or his designee, and such exceptions are reported to the Board of Directors on a quarterly basis.

This policy may be revised from time to time by the officers of the Corporation in consultation with the Board of Directors without prior notice.

These restrictions do not apply to the Fidelity Prime Money Market Portfolio, to certain asset allocation programs (including mutual funds that invest in other mutual funds for asset allocation purposes, and not for short-term trading), to omnibus accounts (except to the extent noted in the next paragraph) maintained by brokers and other financial intermediaries (including 401(k) or other group retirement accounts, although restrictions on Fund share transactions comparable to those set forth in the previous paragraphs have been applied to the Advisor’s retirement savings program), and to involuntary transactions and automatic investment programs, such as dividend reinvestment or transactions pursuant to the Fund’s systematic investment or withdrawal program.

In an attempt to detect and deter excessive trading in omnibus accounts, the Corporation or its agents may require intermediaries to impose restrictions on the trading activity of accounts traded through those intermediaries. The Fund’s ability to impose restrictions with respect to accounts traded through particular intermediaries may vary depending on the systems capabilities, applicable contractual and legal restrictions, and cooperation of those intermediaries. The Corporation, however, cannot always identify or reasonably detect excessive trading that may be facilitated by financial intermediaries or that may be made difficult to identify through the use of omnibus accounts by those intermediaries that transmit purchase, exchange and redemption orders to the Fund, and thus the Fund may have difficulty curtailing such activity.

Distributions and Taxes

The amount of dividends of net investment income and distributions of net realized long and short-term capital gains payable to shareholders will be determined separately for each Fund class. Dividends and distributions are paid separately for each class of shares. The dividends and distributions paid on Class I shares will generally be higher than those paid on Class N shares since Class N shares normally have higher expenses than Class I shares. Dividends from the net investment income of the Fund will be declared and paid annually. The Fund will distribute any net realized long or short-term capital gains at least annually. Your distributions from the Fund will be reinvested in the Fund unless you instruct the Fund otherwise in writing or by telephone. An investor will be taxed in the same manner whether you receive your distributions (from investment company taxable income or net capital gains) in cash or reinvest them in additional shares of the Fund.

There are no fees or sales charges on reinvestments. You may request distributions be paid by check. Any undeliverable dividend checks or dividend checks that remain uncashed for six months will be cancelled and will be reinvested in the Fund at the per share net asset value determined at the date of cancellation.

Distributions of the Fund’s investment company taxable income (which include, but are not limited to, interest dividends and net short-term capital gains), if any, are generally taxable to the Fund’s shareholders as ordinary income. To the extent that the Fund’s ordinary income distributions consist of “qualified dividend” income, such income may be subject to tax at the reduced rate of tax applicable to non-corporate shareholders for net long-term capital gains, if certain holding period requirements have been satisfied by the Fund and the shareholders. Dividends received by the Fund from a REIT and from certain foreign corporations generally will not constitute qualified dividend income.

Distributions of net capital gains (net long-term capital gains less net short-term capital loss) are generally taxable as long-term capital gains regardless of the length of time a shareholder has owned shares of the Fund. Generally, the maximum individual federal tax rate applicable to “qualified dividend income” and long-term capital gains is 20%.

An additional 3.8% federal tax is imposed on certain net investment income (including ordinary dividends and capital gain distributions received from the Fund and net gains from redemptions or other taxable dispositions of Fund shares) of

U.S. individuals, estates and trusts to the extent that such person’s “modified adjusted gross income” (in the case of an individual) or “adjusted gross income” (in the case of an estate or trust) exceeds certain threshold amounts.

Shareholders who sell or redeem shares generally will have a capital gain or loss from the sale or redemption. The amount of gain or loss and the applicable rate of tax will depend generally on the amount paid for the shares, the amount received from the sale or redemption, and how long the shares were held by a shareholder.

The Fund may be subject to foreign withholding or other foreign taxes on income or gain from certain foreign securities. In general, the Fund may deduct these taxes in computing its taxable income. If more than 50% of the value of the Fund’s total assets at the close of its taxable year consists of securities of foreign corporations, the Fund will be eligible and may elect to treat a proportionate amount of certain foreign taxes paid by it as a distribution to each shareholder, which would (subject to applicable limitations) generally permit each shareholder (1) to credit this amount or (2) to deduct this amount for purposes of computing its U.S. federal income tax liability. This will be reported by the Fund on Form 1099-DIV annually, if applicable.

The Fund’s transactions in derivatives (such as futures contracts, swaps and covered call options) will be subject to special tax rules, the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund’s securities and convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund’s use of derivatives may result in the Fund realizing more short-term capital gains and ordinary income subject to tax at ordinary income tax rates than it would if it did not use derivatives.

The Fund may be required to withhold U.S. federal income tax (currently, at a rate of 28%) on all distributions to shareholders if they fail to provide the Fund with their correct taxpayer identification number or to make required certifications, or if they have been notified by the IRS that they are subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld may be credited against U.S. federal income tax liability.

Foreign shareholders may be subject to different U.S. federal income tax treatment, including withholding tax at the rate of 30% on amounts treated as ordinary dividends from the Fund

(and, under certain circumstances, at the rate of 35% on certain capital gain dividends and other dividends), as discussed in more detail in the SAI.

Shareholders will be advised annually as to the federal tax status of distributions made by the Fund for the preceding calendar year. Distributions by the Fund may also be subject to state and local taxes. Additional tax information may be found in the SAI. This section is not intended to be a full discussion of tax laws and the effect of such laws on you. There may be other federal, state, or local tax considerations applicable to a particular investor. You are urged to consult your own tax advisor.

Portfolio Holdings Information

A description of the Fund’s policies and procedures with respect to the disclosure of its portfolio securities is available in the SAI. Currently, disclosure of the Fund’s portfolio holdings is required to be made quarterly within 60 days of the end of each fiscal quarter in the annual report and semi-annual report to shareholders and in the quarterly holdings report on Form N-Q. The SAI and Form N-Q are available, free of charge, on the EDGAR Database on the SEC’s website at www.sec.gov. The annual reports, semi-annual reports, Form N-Q and SAI for the Fund are also available by contacting the Fund at 1-800-FUND TCW (1-800-386-3829) and on the Corporation’s website at www.tcw.com.

Because the Fund has not commenced operations as of the date of this prospectus, financial highlights are not available.

American Depository Receipts (ADRs) — Receipts typically issued by a U.S. bank or trust company evidencing ownership of the underlying foreign securities. ADRs are denominated in U.S. dollars and are publicly traded on exchanges or over-the-counter markets in the U.S.

Benchmark — Any basis of measurement, such as an index, that is used by an investment manager as a yardstick to assess the performance of a portfolio. For example, the S&P 500^® Index is a commonly used benchmark for U.S. large-cap equity portfolios.

Distribution and/or Service (12b-1) Fees — Fees assessed to shareholders for shareholder servicing, marketing and distribution expenses for a fund.

Dividends — A distribution of corporate earnings to shareholders.

Expense Ratio — Expressed as a percentage provides an investor the total cost for fund operating expenses and management fees.

Forward Contract — A specific form of counterparty agreement under which a commodity or financial instrument is bought or sold at a certain price agreed on today (date of contract), but is to be delivered on a stated future (forward) date in settlement of the agreement. If the value of the underlying commodity or financial instrument changes, the value of the forward contract becomes positive or negative depending on the position held.

Futures — A standardized, transferable, exchange-traded contract that requires delivery of a security, commodity, bond, currency or stock index, at a specified price, on a specified future date. Futures represent a pledge to make a certain transaction at a future date and are usually cash settled before the close out date by a party to the contract.

Interest — Cost of using money, expressed as a rate per period of time, usually one year, in which case it is called an annual rate of interest.

Large-Capitalization Companies — Large-capitalization companies are established companies that are considered “known quantities.” Large-capitalization companies often have the resources to weather economic shifts, although they can be slower to innovate than small companies.

Options — An owner of a call (put) option has the right (but not the obligation) to purchase (sell) the underlying security at a specified price, and this right lasts until a specified date. The writer of a call (put) option has the obligation to sell (purchase) the underlying security at a specified price, until a specified date.

Real Estate Investment Trust (REIT) — A REIT is a pooled investment vehicle that invests primarily in income-producing real estate or real estate loans or interests. REITs are not taxed on income distributed to shareholders, provided they comply with the requirements of the Internal Revenue Code of 1986, as amended.

Small- and Mid-Capitalization Companies — Small- and Mid-capitalization companies are less well established companies but in many cases are faster-growing than large-capitalization companies. Because they are less established, small- and mid-capitalization companies’ stocks are usually more volatile than large-capitalization companies’ stocks.

Total Return — Return on an investment including both appreciation (depreciation) and interest or dividends.

Turnover — Statistical ratio measuring the amount of transactions within a portfolio over a given time period.
