The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio

turnover 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 the annual fund operating expenses or in the example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 9% of the average value of its portfolio.

The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Schwab® ETFs (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds and exchange-traded funds (ETFs).

The fund intends to invest in a combination of underlying funds; however, the fund may invest directly in equity and fixed income securities as well as other unaffiliated mutual funds or ETFs, and cash and cash equivalents (including money market funds).

The fund intends to allocate investments among various asset classes such as equity, fixed income and cash and cash equivalents (including money market funds). The fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation. The fund’s target asset allocation is not fixed, and the fund has the flexibility to move within the following asset allocation ranges (under normal market conditions) at the discretion of the investment adviser: 30%-70% equity; 30%-70% fixed income; and 0%-12% cash and cash equivalents (including money market funds). Market appreciation or depreciation may cause the fund to be temporarily outside these ranges.

The fund is designed to offer shareholders an annual payout of approximately 5% during most market environments. However, the fund’s actual annual payout could be higher or lower based on the market environment during that year. The fund intends to make twelve monthly distributions to shareholders at the end of each month. The amounts distributed to shareholders may not be the same each month. The amount of the fund’s distributions in respect of any period may exceed the amount of the fund’s income and gains for that period. In that case, some or all of the fund’s distributions may constitute a return of capital to shareholders.

For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the fund may invest up to 100% of its assets directly in cash, money market instruments, repurchase agreements and other short-term obligations. When the fund engages in such activities, it may not achieve its investment objective.

4Schwab Monthly Income Fund — Target Payout  | Fund Summary

The after-tax figures reflect the highest individual federal income tax rates in effect during the period and do not reflect the impact of state and local taxes. Your actual after-tax returns depend on your individual tax situation. In addition, after-tax returns are not relevant if you hold your fund shares through a tax-deferred arrangement, such as a 401(k) plan, an individual retirement account (IRA) or other tax-advantaged account. In some cases, the return after taxes on distributions and sale of shares may exceed the fund’s other returns due to an assumed benefit from any losses on a sale of shares at the end of the measurement period.

The fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Schwab® ETFs (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds and exchange-traded funds (ETFs).

The fund is designed to offer shareholders an annual payout of 4-6% during most market environments. In addition, the fund seeks to maximize the annual payout while also maintaining or growing the level of investment over the long term. However, the fund’s actual annual payout could be higher or lower based on the underlying fund yields and market environment during that year and other forward-looking factors.

Portfolio Managers

Zifan Tang, Ph.D., CFA, Senior Portfolio Manager, is responsible for the day-to-day co-management of the fund. She has managed the fund since 2012.

Drew Hayes, CFA, Portfolio Manager, is responsible for the day-to-day co-management of the fund. He has managed the fund since 2022.

Patrick Kwok, CFA, Portfolio Manager, is responsible for the day-to-day co-management of the fund. He has managed the fund since 2019.

Purchase and Sale of Fund Shares

The fund is open for business each day that the New York Stock Exchange (NYSE) is open. If the NYSE is closed due to weather or other extenuating circumstances on a day it would typically be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, the fund reserves the right to treat such day as a business day and accept purchase and redemption orders and calculate its share price as of the normally scheduled close of regular trading on the NYSE for that day.

Investors may only invest in the fund through an account at Charles Schwab & Co., Inc. (Schwab) or another financial intermediary. When you place orders to purchase, exchange or redeem fund shares through an account at Schwab or another financial intermediary, you must follow Schwab’s or the other financial intermediary’s transaction procedures.

There is no minimum initial investment for the fund.

Tax Information

Dividends and capital gains distributions received from the fund will generally be taxable as ordinary income or capital gains, unless you are investing through an IRA, 401(k) or other tax-advantaged account (in which case you may be taxed later, upon withdrawal of your investment from such account).

Payments to Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the fund and its related companies 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 financial intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Schwab Monthly Income Fund — Income Payout  | Fund Summary15​

About the Funds

The Schwab Monthly Income Funds (the funds) share the same investment approach: each seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Schwab® ETFs (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds and exchange-traded funds (ETFs). The funds are designed to generate monthly income payments and appreciate capital over the long term. The funds may be appropriate for investors who are seeking monthly income payments and who are willing to accept the risks associated with the funds’ asset allocation strategies. Because the funds invest in other funds, each fund is considered a “fund of funds.”

The funds are designed for long-term investors. Their performance will fluctuate over time and, as with all investments, future performance may differ from past performance.

Investor Profile

The funds are designed to offer investors a professionally managed investment plan that simplifies the investment management of an investor’s assets. In particular, the funds may be appropriate for investors seeking current income and the opportunity for future growth potential.

A fund reserves the right to modify its targeted annual payout should circumstances warrant a change.

Who may want to invest in the funds?

The funds may be a suitable investment for investors:

•

seeking funds that combine the potential for income and capital appreciation

​

•

seeking funds that allocate their assets among both equity and fixed income investments

​

Who may not want to invest in the funds?

The funds may not be suitable for investors:

•

seeking to invest for a short period of time

​

•

uncomfortable with fluctuations in the value of their investment

​

•

seeking to use the funds for educational savings accounts

16Schwab Monthly Income Funds | About the Funds

Fund Details

Investment Objectives

Each fund seeks to provide current income and, as a secondary investment objective, capital appreciation.

Except with respect to the Schwab Monthly Income Fund — Flexible Payout, each fund’s investment objective is not fundamental and therefore may be changed by the fund’s board of trustees without shareholder approval.

Investment Strategies

Each fund seeks to achieve its investment objective by investing primarily in a combination of Schwab Funds® and Schwab® ETFs (the underlying funds) in accordance with its target asset allocation. The investment adviser will allocate assets among the underlying funds, which will include equity funds, fixed income funds, and money market funds and ETFs.

Each fund intends to invest in a combination of underlying funds; however, each fund may invest directly in equity and fixed income securities as well as other unaffiliated mutual funds or ETFs, and cash and cash equivalents (including money market funds).

For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, each fund may invest up to 100% of its assets directly in cash, money market instruments, repurchase agreements and other short-term obligations. When a fund engages in such activities, it may not achieve its investment objective.

Description of Asset Allocation Strategies

Each fund intends to allocate investments among various asset classes such as equity, fixed income, cash and cash equivalents (including money market funds). Each fund has its own distinct asset allocation strategy that is designed to accommodate the fund’s targeted annual payout percentage while taking into account the fund’s specific risk tolerances and desired level of capital appreciation.

Each fund’s target asset allocation is not fixed, and each fund has the flexibility to move within the asset allocation ranges set forth below at the discretion of the investment adviser:

Asset Class (Target Allocation Range — Under Normal Market Conditions)*

Market appreciation or depreciation may cause a fund to be temporarily outside the ranges identified in the table.

Description of Distribution Goals

Each fund’s distribution goal is to provide a targeted annual payout of income to shareholders. The targeted annual payout for each fund is as follows:

A fund’s actual annual payout could be higher or lower than the targeted annual payout based on market environment during that year.

As mentioned above, each fund’s actual annual payout may be higher or lower than the fund’s targeted annual payout. There is no guarantee that a fund will be able to achieve its distribution goal during any given year. In addition to the interest rate environment discussed above, a fund’s actual annual payout could also be affected by a number of other factors, including, without limitation, the performance of the financial markets in which the fund invests, the allocation of fund assets across different asset classes and investments, the performance of the fund’s investment strategies, and the amount and timing of prior distributions by the fund.

guarantee that a fund will make monthly income payments to its shareholders. Each fund may make an additional distribution at the end of the year in order to comply with applicable law. This additional distribution may include an income component that may be higher or lower than a fund’s regular monthly income payment.

Although it cannot be guaranteed, the Income Payout Fund does not expect to make distributions that will be treated as return of capital. The amount of the distributions made by each of the Target Payout Fund and the Flexible Payout Fund in respect of any period may exceed the amount of the fund’s income and gains for that period. In that case, some or all of the distributions made by the Target Payout Fund and the Flexible Payout Fund may constitute a return of capital to shareholders. At the end of the year, the funds may be required under applicable law to recharacterize distributions for the year among ordinary income, capital gains, and return of capital (if any) for purposes of tax reporting to shareholders.

More Information About Principal Investment Risks

Conflicts of Interest Risk. The investment adviser’s authority to select and substitute underlying funds from a variety of affiliated and unaffiliated mutual funds and ETFs may create a conflict of interest because the fees paid to it and its affiliates by some underlying funds are higher than the fees paid by other underlying funds. The investment adviser also may have an incentive to select an affiliated underlying fund for other reasons, including to increase assets under management or to support new investment strategies. In addition, other conflicts of interest may exist. For example, the investment adviser’s decisions to cause a fund to purchase or redeem shares of an affiliated underlying fund could be influenced by its belief that an affiliated underlying fund may benefit from additional assets or that it is in the best interests of the affiliated underlying fund to limit purchases of shares of the underlying fund. In such cases, the best interests of the affiliated underlying fund may not be aligned with those of the fund. However, the investment adviser is a fiduciary to each fund and is legally obligated to act in each fund’s best interests when selecting underlying funds.

Market Risk. Financial markets rise and fall in response to a variety of factors, sometimes rapidly and unpredictably. Markets may be impacted by economic, political, regulatory and other conditions, including economic sanctions and other government actions. In addition, the occurrence of global events, such as war, terrorism, environmental disasters, natural disasters and epidemics, may also negatively affect the financial markets. These events could reduce consumer demand or economic output; result in market closures, changes in interest rates, inflation/deflation, travel restrictions or quarantines; and significantly adversely impact the economy. Governmental and quasi-governmental authorities and regulators throughout the world have in the past often responded to serious economic disruptions with a variety of significant fiscal and monetary policy changes which could have an unexpected impact on financial markets and a fund’s investments. As with any investment whose performance is tied to these markets, the value of an investment in a fund will fluctuate, which means that an investor could lose money over short or long periods.

ETF Risk. When the fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a proportionate share of the ETF’s expenses. Therefore, it may be more costly to own an ETF than to own the underlying securities directly. In addition, while the risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF holds, lack of liquidity in the market for an ETF’s shares can result in its value being more volatile than the underlying portfolio of securities.

Operational Risk. Each fund is exposed to operational risk arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the fund’s service providers, counterparties or other third parties, failed or inadequate processes and technology or system failures. Each fund seeks to reduce these operational risks through controls and procedures believed to be reasonably designed to address these risks. However, these controls and procedures cannot address every possible risk and may not fully mitigate the risks that they are intended to address.

Managed Payout Risk. Because the Target Payout and Flexible Payout Funds are expected to make monthly payments regardless of investment performance, the amount of each fund’s distributions in respect of any period often will exceed the amount of the fund’s income and gains for that period. In that case, some or all of the fund’s distributions may constitute a return of capital to shareholders. It is possible for the funds to suffer substantial investment losses and simultaneously experience additional asset reductions as a result of its payments to shareholders under the managed payout policy. In addition, in order to make the payments called for under the funds’ managed payout policy, the funds may have to sell portfolio securities at a time when it would not otherwise do so.

A return of capital distribution generally will not be taxable but will decrease the shareholder’s cost basis in the shares of the fund and will result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the fund as capital assets. A distribution constituting a return of capital is not a distribution of income or capital gains earned by the fund, and should not be confused with the funds’ “yield” or “income.”

the underlying funds in which the fund may invest and the types of investments made by those underlying funds. These risks include any combination of the risks described below, although the fund’s exposure to a particular risk will depend on the fund’s overall asset allocation and underlying fund allocation.

•

Investment Style Risk. Some underlying funds seek to track the performance of various segments of the stock market, as measured by their respective indices. Each underlying fund follows these stocks during upturns as well as downturns. Because of their indexing strategy, the underlying funds do not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of an underlying fund’s expenses, the underlying fund’s performance is normally below that of the index. Market disruptions could cause delays in an underlying fund’s index’s rebalancing schedule which may result in the index and, in turn, the underlying fund experiencing returns different than those that would have been achieved under a normal rebalancing schedule. A significant percentage of the index may be composed of securities in a single industry or sector of the economy. If the underlying fund is focused in an industry or sector, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy.

​

•

Management Risk. Certain underlying funds are actively managed mutual funds. Any actively managed mutual fund is subject to the risk that its investment adviser (or sub-adviser) will select investments or allocate assets that could cause a fund to underperform or otherwise not meet its objective. An underlying fund’s adviser applies its own investment techniques and risk analyses in making investment decisions for the fund, but there can be no guarantee that they will produce the desired results. In addition, with respect to certain of the underlying funds, the investment adviser makes investment decisions for the fund using a strategy based largely on historical information. There is no guarantee that a strategy based on historical information will produce the desired results in the future. In addition, the portfolio optimization processes used by some underlying funds to assist in constructing the underlying fund’s portfolio does not assure successful investments. As a result, the underlying fund may have a lower return than if it were managed using another process or strategy.

​

•

Equity Risk. The prices of equity securities in which the underlying funds invest rise and fall daily. These price movements may result from factors affecting individual companies, industries or the securities market as a whole. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may suffer a decline in response. Governmental action, including the imposition of trade embargoes or tariffs, may also impact individual companies or markets as a whole. In addition, the equity market tends to move in cycles, which may cause stock prices to fall over short or extended periods of time. Due to their fixed income features, preferred stocks provide higher income potential than issuers’ common stocks, but typically are more sensitive to interest rate changes than the underlying common stock. The rights of common stockholders are generally subordinate to the rights associated with an issuer’s preferred stocks and the rights of preferred stockholders are generally subordinate to the rights associated with an issuer’s debt securities on the distribution of an issuer’s assets in the event of a liquidation.

​

•

Market Capitalization Risk. Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. In addition, there may be less trading volume in securities issued by mid- and small-cap companies than those issued by larger companies and, as a result, trading volatility may have a greater impact on the value of securities of mid- and small-cap companies. Securities issued by large-cap companies, on the other hand, may not be able to attain the high growth rates of some mid- and small-cap companies. During a period when securities of a particular market capitalization fall behind other types of investments, an underlying fund’s performance could be impacted.

​

•

Large-Cap Company Risk. Large-cap companies are generally more mature than smaller companies. They also may have fewer new market opportunities for their products or services, may focus resources on maintaining their market share, and may be unable to respond quickly to new competitive challenges. As a result, the securities issued by these companies may not be able to reach the same levels of growth as the securities issued by small- or mid-cap companies.

​

•

Mid-Cap Company Risk. Mid-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by large-cap companies. The value of securities issued by mid-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns.

​

•

Small-Cap Company Risk. Small-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and their securities may be riskier than those issued by larger companies. The value of securities issued by small-cap companies may be based in substantial part on future expectations rather than current achievements and their prices may move sharply, especially during market upturns and downturns. In addition, small-cap companies may have limited financial resources, management experience, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies. Further, small-cap companies may have less publicly available information and such information may be inaccurate or incomplete.

ETF Risk. When an underlying fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a proportionate share of the ETF’s expenses. Therefore, it may be more costly to own an ETF than to own the underlying securities directly. In addition, while the risks of owning shares of an ETF generally reflect the risks of owning the underlying securities the ETF holds, lack of liquidity in the market for an ETF’s shares can result in its value being more volatile than the underlying portfolio of securities.

​

•

Convertible Securities Risk. Certain of the underlying funds may invest in convertible securities. Convertible securities have the potential for a higher dividend or interest yield and lower price volatility compared to common stock. The value of a convertible security is influenced by the credit standing of the issuer and changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The price of a convertible security is also subject to the same types of market and issuer risks as the underlying common stock because of the conversion or exercise feature.

​

•

Interest Rate Risk. Interest rates rise and fall over time. As with any investment whose yield reflects current interest rates, an underlying fund’s yield will change over time. During periods when interest rates are low or there are negative interest rates, an underlying fund’s yield (and total return) also may be low or the underlying fund may be unable to maintain positive returns. Changes in interest rates also may affect an underlying fund’s share price: a rise in interest rates generally causes an underlying fund’s share price to fall. This risk is greater when an underlying fund holds fixed-income securities with longer maturities. The longer an underlying fund’s portfolio duration, the more sensitive to interest rate movements its share price is likely to be. For example, an underlying fund with a longer portfolio duration is more likely to experience a decrease in its share price as interest rates rise. Duration is an estimate of a security’s (or portfolio of securities) sensitivity to changes in prevailing interest rates that is based on certain factors that may prove to be incorrect. It is therefore not an exact measurement and may not be able to reliably predict a particular security’s price sensitivity to changes in interest rates.

​

Economic conditions and other factors, including a central bank’s monetary policy, may result in changes in interest rates, which could have sudden and unpredictable effects on the markets and significantly impact the value of fixed-income securities in which an underlying fund invests. Rising interest rates may decrease liquidity in the fixed-income securities markets, making it more difficult for an underlying fund to sell its fixed-income securities holdings at a time when the investment adviser might wish to sell such securities. In addition, decreased market liquidity also may make it more difficult to value some or all of an underlying fund’s fixed-income securities holdings. Certain countries have experienced negative interest rates on certain fixed-income securities. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. To the extent that the investment adviser of an underlying fund anticipates interest rate trends imprecisely, the underlying fund could miss yield opportunities or its share price could fall. Inflation-protected securities may react differently to interest rate changes than other types of fixed-income securities and tend to react to changes in “real” interest rates.

•

Credit Risk. A decline in the credit quality of an issuer or guarantor of a portfolio investment could cause an underlying fund to lose money or underperform. An underlying fund could lose money if, due to a decline in credit quality, the issuer or guarantor of a portfolio investment fails to make, or is perceived as being unable or unwilling to make, timely principal or interest payments or otherwise honor its obligations. The credit quality of an underlying fund’s portfolio holdings can change rapidly in certain market environments and any default on the part of a single portfolio investment could cause an underlying fund’s share price or yield to fall. Certain U.S. government securities that an underlying fund invests in are not backed by the full faith and credit of the U.S. government, which means they are neither issued nor guaranteed by the U.S. Treasury. There can be no assurance that the U.S. government will provide financial support to securities of its agencies and instrumentalities if it is not obligated to do so under law. Also, any government guarantees on securities an underlying fund owns do not extend to the shares of the underlying fund itself. Below investment-grade bonds (junk bonds) involve greater risks of default or downgrade and are more volatile than investment-grade bonds. Below investment-grade bonds also involve greater risk of price declines than investment-grade securities due to actual or perceived changes in an issuer’s creditworthiness. In addition, issuers of below investment-grade bonds may be more susceptible than other issuers to economic downturns. Such bonds are subject to the risk that the issuer may not be able to pay interest or dividends and ultimately to repay principal upon maturity. Discontinuation of these payments could substantially adversely affect the market value of the bonds.

​

•

Prepayment and Extension Risk. Certain fixed-income securities are subject to the risk that the securities may be paid off earlier or later than expected, especially during periods of falling or rising interest rates, respectively. Rising interest rates tend to extend the duration of certain fixed-income securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, an underlying fund could exhibit additional volatility and hold securities paying lower-than-market rates of interest. This is known as extension risk. When interest rates decline, borrowers may pay off their fixed-income securities sooner than expected. This can reduce an underlying fund’s returns because the underlying fund will have to reinvest that money at the lower prevailing interest rates. In addition, prepayments and subsequent reinvestments increase the underlying fund’s portfolio turnover rate. This is known as prepayment risk. Either situation could hurt an underlying fund’s performance.

than other debt securities. Small movements in interest rates — both increases and decreases — may quickly and significantly affect the value of certain mortgage-backed securities. In addition, certain of the mortgage-backed securities in which an underlying fund may invest are issued or guaranteed by agencies or instrumentalities of the U.S. government but are not backed by the full faith and credit of the U.S. government and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it was not obligated to do so which can cause an underlying fund to lose money or underperform. The risks of investing in mortgage-backed securities include, among others, interest rate risk, credit risk, prepayment risk and extension risk, as well as risks associated with the nature of the underlying mortgage assets and the servicing of those assets. These securities are subject to the risk of default on the underlying mortgages, and such risk is heightened during periods of economic downturn. Transactions in mortgage pass-through securities often occur through to-be-announced (TBA) transactions. If a TBA counterparty defaults or goes bankrupt an underlying fund may experience adverse market action, expenses, or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in a TBA transaction which can cause an underlying fund to lose money or underperform.

•

​

•

Mortgage Dollar Rolls Risk. Mortgage dollar rolls are transactions in which an underlying fund sells mortgage-backed securities to a dealer and simultaneously agrees to repurchase similar securities in the future at a predetermined price. An underlying fund’s mortgage dollar rolls could lose money if the price of the mortgage-backed securities sold falls below the agreed upon repurchase price, or if the counterparty is unable to honor the agreement.

​

•

Money Market Fund Risk. In addition to the risks discussed under “Investment Risk” above, an investment by a fund in an underlying money market fund has additional risks. A fund may invest in underlying money market funds that either seek to maintain a stable $1.00 net asset value (“stable share price money market funds”) or that have a share price that fluctuates (“variable share price money market funds”). Although an underlying stable share price money market fund seeks to maintain a stable $1.00 net asset value, it is possible to lose money by investing in such a money market fund. Because the share price of an underlying variable share price money market fund will fluctuate, when a fund sells the shares it owns they may be worth more or less than what the fund originally paid for them. In addition, neither type of money market fund is designed to offer capital appreciation. In exchange for their emphasis on stability and liquidity, money market investments may offer lower long-term performance than stock or bond investments. Certain underlying money market funds may impose a fee upon the sale of shares under certain circumstances.

​

•

Foreign Investment Risk. An underlying fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. In certain countries, legal remedies available to investors may be more limited than those available with respect to investments in the U.S. These risks may negatively impact the value or liquidity of an underlying fund’s investments and could impair the underlying fund’s ability to meet its investment objective or invest in accordance with its investment strategy. In addition, an underlying fund’s investments in foreign securities may be subject to economic sanctions or other government restrictions, including trade tariffs, embargoes or limitations on trade which could have a significant impact on a country’s markets overall as well as global economies or markets. There also is the risk that the cost of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions. The securities of some foreign companies may be less liquid and, at times, more volatile than securities of comparable U.S. companies. An underlying fund may also experience more rapid or extreme changes in value as compared to an underlying fund that invests solely in securities of U.S. companies because the securities markets of many foreign countries are relatively small, with a limited number of companies representing a small number of industries. To the extent an underlying fund’s investments in a single country or a limited number of countries represent a large percentage of the underlying fund’s assets, the underlying fund’s performance may be adversely affected by the economic, political, regulatory and social conditions in those countries, and the underlying fund’s price may be more volatile than the price of an underlying fund that is geographically diversified.

many China-based operating companies have created VIE structures. In a VIE structure, a China-based operating company will establish an entity outside of China that will enter into service and other contracts with the China-based operating company. Shares of the entities established outside of China are often listed and traded on an exchange. Non-Chinese investors (such as an underlying fund) hold equity interests in the entities established outside of China rather than directly in the China-based operating companies. This arrangement allows U.S. investors to obtain economic exposure to the China-based operating company through contractual means rather than through formal equity ownership. An investment in a VIE structure subjects an underlying fund to the risks associated with the underlying China-based operating company. In addition, an underlying fund may be exposed to certain associated risks, including the risks that: the Chinese government could subject the China-based operating company to penalties, revocation of business and operating licenses or forfeiture of ownership interests; the Chinese government may outlaw the VIE structure, which could cause an uncertain negative impact to existing investors in the VIE structure; the contracts underlying the VIE structure may not be enforced by Chinese courts; and shareholders of the China-based operating company may leverage the VIE structure to their benefit and to the detriment of the investors in the VIE structure. If these actions were to occur, the market value of an underlying fund’s investments in the VIE structure would likely fall, causing investment losses, which could be substantial, for the underlying fund.

•

Emerging Markets Risk. The risks of foreign investments apply to, and may be heightened in connection with, investments in emerging market countries or securities of issuers that conduct their business in emerging markets. Emerging market countries may be more likely to experience political turmoil or rapid changes in market or economic conditions than more developed countries. Emerging market countries often have less uniformity in accounting, auditing, financial reporting and recordkeeping requirements and greater risk associated with the custody of securities. It is sometimes difficult to obtain and enforce court judgments in such countries. Material information about a company in an emerging market country may be unavailable or unreliable, and U.S. regulators may be unable to enforce a company’s regulatory obligations. There is often a greater potential for nationalization, expropriation, confiscatory taxation, government regulation, social instability or diplomatic developments (including war) in emerging market countries, which could adversely affect the economies of, or investments in securities of issuers located in, such countries. In addition, emerging markets are substantially smaller than developed markets, and the financial stability of issuers (including governments) in emerging market countries may be more precarious than in developed countries. As a result, there will tend to be an increased risk of illiquidity and price volatility associated with an underlying fund’s investments in emerging market countries which may be magnified by currency fluctuations relative to the U.S. dollar, and, at times, it may be difficult to value such investments.

​

•

Currency Risk. An underlying fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, will subject the underlying fund 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 hedged. In either event, the dollar value of an investment in an underlying fund would be adversely affected. Currency exchange rates may fluctuate in response to factors extrinsic to that country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates; intervention (or failure to intervene) by U.S. or foreign 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 United States or abroad. These can result in losses to an underlying fund if it is unable to deliver or receive currency or monies in settlement of obligations and could also cause hedges it has entered into to be rendered useless, resulting in full currency exposure as well as incurring transaction costs. Forward contracts on foreign currencies are not traded on exchanges; rather, a bank or dealer will act as agent or as principal in order to make or take future delivery of a specified lot of a particular currency for the underlying fund’s account. An underlying fund is subject to the risk of a counterparty’s failure, inability or refusal to perform with respect to such contracts.

​

•

Real Estate Investment Risk. Certain of the underlying funds have a policy of concentrating their investments in real estate companies and companies related to the real estate industry. As such, an underlying fund is subject to risks associated with the direct ownership of real estate securities and a fund’s investment in such an underlying fund will be closely linked to the performance of the real estate markets. An investment by a fund in an underlying fund that invests, but does not concentrate, in real estate companies and companies related to the real estate industry will subject the fund to the risks associated with the direct ownership of real estate securities to a lesser extent. These risks include, among others, declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; defaults by borrowers or tenants, particularly during an economic downturn; increasing competition; increases in property taxes and operating expenses; changes in zoning laws; losses due to costs resulting from the clean-up of environmental problems; liability to third parties for damages resulting from environmental problems; casualty or condemnation losses; limitations on rents; changes in market and sub-market values and the appeal of properties to tenants; and changes in interest rates.

self-liquidation. In addition, REITs could possibly fail to qualify for tax free pass-through of income under the Internal Revenue Code of 1986, as amended, or to maintain their exemptions from registration under the Investment Company Act of 1940. The failure of a company to qualify as a REIT under federal tax law may have adverse consequences to an underlying fund that invests in that REIT. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting its investments. In addition, REITs have their own expenses, and an underlying fund that invests in REITs will bear a proportionate share of those expenses. Additionally, dividends paid by REITs are taxed as ordinary income and generally do not qualify for the preferential rate applicable to qualified dividend income.

•

Short Sales Risk. Certain underlying funds may engage in short sales, which are transactions in which the underlying fund sells a security it does not own. To complete a short sale, an underlying fund must borrow the security to deliver to the buyer. The underlying fund is then obligated to replace the borrowed security by purchasing the security at the market price at the time of replacement. This price may be more or less than the price at which the security was sold by the underlying fund and the underlying fund will incur a loss if the price of the security sold short increases between the time of the short sale and the time the underlying fund replaces the borrowed security.

​

•

High-Yield Risk. An underlying fund may invest in high-yield securities and unrated securities of similar credit quality (junk bonds) may be subject to greater levels of credit and liquidity risk than funds that do not invest in such securities. These securities are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. High-yield securities may be more volatile than higher-rated securities. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce the underlying fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the underlying fund may lose its entire investment. Because of the risks involved in investing in high-yield securities, an investment in a fund that invests in such securities should be considered speculative.

​

•

Floating Rate Loan Risk. Floating rate loans often have contractual restrictions on resale. These restrictions can delay or impede the underlying fund’s ability to sell loans and may adversely affect the price that can be obtained. Loans and unlisted securities are typically less liquid than securities traded on national exchanges. The secondary market for loans may be subject to irregular trading activity and extended settlement periods, and the liquidity of bank loans can vary significantly over time. For example, if the credit quality of a bank loan unexpectedly declines significantly, secondary market trading in that floating rate loan can also decline. During periods of infrequent trading, valuing a bank loan can be more difficult and buying or selling a loan at an acceptable price may not be possible or may be delayed. A delay in selling a floating rate loan can result in a loss and cause the underlying fund’s price to decline. When the underlying fund purchases a loan as an assignment, it will be subject to the credit risk of the borrower. When the underlying fund purchases a loan as a participation interest, it does not have any direct claim on the loan or its collateral, or any rights of set-off against the borrower. As a result, the underlying fund will be subject not only to the credit risk of the borrower but also to the credit risk of the lender or participant who sold the participation interest to the underlying fund. In the event of the insolvency of the lender selling a participation interest, the underlying fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. Unlike registered securities, such as most stocks and bonds, loans are not registered or regulated under the federal securities laws. As a result, investors in loans have less protection against fraud and other improper practices than investors in registered securities because investors in loans may not be entitled to rely on the protection of the federal securities laws.

​

?

•

Derivatives Risk. An underlying fund may use derivatives to enhance returns or hedge against market declines. Examples of derivatives are options, futures, options on futures, forward contracts and swaps. An option is the right, but not the obligation, to buy or sell an instrument at a specific price on or before a specific date. A future is an agreement to buy or sell a financial instrument at a specific price on a specific day. A forward contract is an over-the-counter derivative transaction between two parties to buy or sell a specified amount of an underlying reference at a specified price (or rate) on a specified date in the future. A forward foreign currency contract is a derivative (forward contract) in which the underlying reference is a country’s or region’s currency. A swap is an agreement whereby two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities and a predetermined amount. A credit default swap is an agreement in which the seller agrees to make a payment to the buyer in the event of a specified credit event in exchange for a fixed payment or series of fixed payments. An underlying fund’s use of derivatives, that are subject to regulation by the Commodity Futures Trading Commission (CFTC), could cause a fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.

​

increase volatility, and could cause the underlying fund to lose more than the initial amount invested. However, these risks are less severe when the underlying fund uses derivatives for hedging rather than to enhance the underlying fund’s returns or as a substitute for a position or security. An underlying fund’s use of derivatives also could create a risk of counterparty default under certain transactions, risks that a fund would need to liquidate portfolio positions when it may not be advantageous to do so in order to meet margin and payment obligations, and legal risks relating to insufficient documentation, insufficient capacity or authority of a counterparty, or legality or enforceability of a contract.

•

Leverage Risk. Certain underlying fund transactions, such as derivatives transactions, short sales, reverse repurchase agreements, and mortgage dollar rolls, may give rise to a form of leverage and may expose the underlying fund to greater risk. In a reverse repurchase agreement, the underlying fund would sell a security and enter into an agreement to repurchase the security at a specified future date and price. Leverage tends to magnify the effect of any decrease or increase in the value of an underlying fund’s portfolio securities. The use of leverage may cause an underlying fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations.

​

•

Multi-Manager Risk. Certain of the underlying funds utilize a multi-manager approach to investing. Although the investment adviser monitors and seeks to coordinate the overall management of these underlying funds, each investment manager makes investment decisions independently, and it is possible that the investment styles of the investment managers may not complement one another. As a result, the exposure of these underlying funds to a given region, country, stock, industry or investment style could unintentionally be smaller or larger than if the underlying funds had a single manager.

​

•

Securities Lending Risk. Certain of the underlying funds may lend their portfolio securities to brokers, dealers, and other financial institutions provided a number of conditions are satisfied, including that the loan is fully collateralized. When an underlying fund lends portfolio securities, its investment performance will continue to reflect changes in the value of the securities loaned, and the underlying fund will also receive a fee or interest on the collateral. Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent. An underlying fund may pay lending fees to a party arranging the loan. An underlying fund will also bear the risk of any decline in the value of securities acquired with cash collateral.

​

•

Liquidity Risk. Liquidity risk exists when particular investments are difficult to purchase, sell or value, especially during stressed market conditions. The market for certain investments may become illiquid due to specific adverse changes in the conditions of a particular issuer or under adverse market or economic conditions independent of the issuer. In addition, limited dealer inventories of certain securities could potentially lead to decreased liquidity. In such cases, an underlying fund’s investments in illiquid securities may reduce the returns of the fund because the underlying fund may be unable to sell the illiquid securities at an advantageous time or price. Further, transactions in illiquid securities may entail transaction costs that are higher than those for transactions in liquid securities. Liquidity risk also includes the risk that market conditions or large shareholder redemptions, which may occur rapidly or unexpectedly, may impact the ability of the underlying fund to meet redemption requests within the required time period. In order to meet such redemption requests, the underlying fund may be forced to sell securities at inopportune times or prices, which could reduce the performance of the underlying fund.

​

•

Redemption Risk. An underlying money market fund may experience periods of heavy redemptions that could cause the underlying fund to liquidate its assets at inopportune times or at a loss or depressed value, particularly during periods of declining or illiquid markets. Redemptions by a few large investors in an underlying money market fund may have a significant adverse effect on the underlying fund’s ability to maintain a stable $1.00 share price. In the event any money market fund fails to maintain a stable net asset value, other money market funds, including an underlying money market fund, could face a market-wide risk of increased redemption pressures, potentially jeopardizing the stability of their $1.00 share prices.

​

•

Tracking Error Risk. Certain underlying funds seek to track the performance of their respective indices, although they may not be successful in doing so. The divergence between the performance of an underlying fund and its index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant. For example, an underlying fund may not invest in certain securities in its index, match the securities’ weighting to the index, or the underlying fund may invest in securities not in the index, due to regulatory, operational, custodial or liquidity constraints; corporate transactions; asset valuations; transaction costs and timing; tax considerations; and index rebalancing, which may result in tracking error. An underlying fund may attempt to offset the effects of not being invested in certain index securities by making substitute investments, but these efforts may not be successful. In certain circumstances, the underlying fund may value individual securities based on fair value prices developed using methods approved by the underlying fund’s board of trustees. To the extent the fund calculates its NAV based on fair value prices, the underlying fund’s performance may diverge from the index. In addition, cash flows into and out of an underlying fund, operating expenses and trading costs all affect the ability of the underlying fund to match the performance of its index, because the index does not have to manage cash flows and does not incur any costs.

The Funds’ Investments in Asset Classes and Sub-Asset Classes

Through each fund’s investments in its underlying funds, each fund aims to provide diversification across major asset classes as well as diversification across a range of sub-asset classes within the major asset classes. Each fund’s allocation to an asset or sub-asset class will change over time. The investment adviser may add or remove asset classes and sub-asset classes at any time without prior notice. For additional details regarding how the adviser determines the funds’ underlying fund and asset class allocations, please refer back to the “Principal Investment Strategies” section in the Fund Summary sections and the section “Fund details: Investment Objectives, Strategies and Risks” in this prospectus.

The following table shows which underlying funds may be used within each asset class and style class and each fund’s target asset allocation to each underlying fund as of the date of this prospectus.

The allocations may not add to 100% due to rounding.

Investing in the Funds

In this section, you will find information on buying, selling and exchanging shares. New investors may only invest in a fund through an intermediary by placing orders through your brokerage account at Schwab or an account with another broker/dealer, investment adviser, 401(k) plan, employee benefit plan, administrator, bank, or other financial intermediary (intermediary) that is authorized to accept orders on behalf of the fund (intermediary orders). You also will see how to choose a distribution option for your investment. Helpful information on taxes is included as well.

The funds are not managed to maximize tax efficiency for taxable shareholder accounts. Investors should consider whether a fund is an appropriate investment in light of their current financial position and retirement needs.

The funds generally are not registered for sale in jurisdictions outside the United States and are intended for purchase by persons residing in the United States. A person is considered resident in the United States if at the time of the investment (i) the account has an address of record in the United States or a U.S. territory (including APO/FPO/DPO) and (ii) all account owners are resident in the United States or a U.S. territory and have a valid U.S. taxpayer identification number. If an existing account is updated to reflect a non-U.S. address, the account may be restricted from making additional investments.

Investing Through a Financial Intermediary

Placing Orders Through Your Intermediary

When you place orders through Schwab or another intermediary, you are not placing your orders directly with the funds, and you must follow Schwab’s or the other intermediary’s transaction procedures. Your intermediary may impose different or additional conditions than the funds on purchases, redemptions and exchanges of fund shares. These differences may include initial, subsequent and maintenance investment requirements, exchange policies, fund choices, cut-off times for investment and trading restrictions. Your intermediary may independently establish and charge its customers transaction fees, account fees and other fees in addition to the fees charged by the funds, and the intermediary may require its customers to pay a commission when transacting in fund shares. These additional fees will vary between intermediaries and may vary over time and would increase the cost of your investment and lower investment returns. You should consult your intermediary directly for information regarding these conditions and fees. The funds are not responsible for the failure of your intermediary to carry out its responsibilities.

Only certain intermediaries are authorized to accept orders on behalf of the funds. If your fund shares are no longer held by an authorized intermediary, the fund may impose restrictions on your ability to manage or maintain your shares. For example, you will not be able to place orders to purchase additional shares. To remove these restrictions, you may move your shares to Schwab or another intermediary that is authorized to accept fund orders.

Buying, Selling and Exchanging Shares Through an Intermediary

To purchase, redeem or exchange shares held in your Schwab account or in your account at another intermediary, you must place your orders with the intermediary that holds your shares. You may not purchase, redeem or exchange shares held in your intermediary account directly with a fund.

When selling or exchanging shares, you should be aware of the following fund policies:

•

For accounts held through a financial intermediary, each fund typically expects to pay sale proceeds to the financial intermediary for payment to redeeming shareholders within two business days following receipt of a shareholder redemption order; however, a fund may take up to seven days to pay sale proceeds.

​

•

The funds reserve the right to honor redemptions in liquid portfolio securities instead of cash when your redemptions over a 90-day period exceed $250,000 or 1% of a fund’s assets, whichever is less. You may incur transaction expenses and taxable gains in converting these securities to cash. In addition, a redemption in liquid portfolio securities would be treated as a taxable event for you and may result in the recognition of gain or loss for federal income tax purposes.

​

•

Exchange orders are limited to other Schwab Funds (that are not Sweep Investments®) and must meet the minimum investment and other requirements for the fund and share class, if applicable, into which you are exchanging.

​

•

You should read the prospectus for the fund into which you are exchanging prior to placing your order.

​

Investing Directly with the Funds

Placing Direct Orders

Investors generally may not purchase shares directly from the funds’ transfer agent, BNY Mellon Investment Servicing (US) Inc. The funds reserve the right to accept direct purchases from certain eligible shareholders (Eligible Shareholders) and to suspend the privilege of directly purchasing additional shares of the funds at any time.

Financial intermediaries and Eligible Shareholders may contact the transfer agent by telephone at 1-877-332-2371.

Share Price

The funds are open for business each day that the NYSE is open. Each fund calculates its share price each business day as of the close of the NYSE (generally 4:00 p.m. Eastern time). If the NYSE is closed due to weather or other extenuating circumstances on a day it would typically be open for business, or the NYSE has an unscheduled early closing on a day it has opened for business, the funds reserve the right to treat such day as a business day and accept purchase and redemption orders and calculate their share price as of the normally scheduled close of regular trading on the NYSE for that day. A fund’s share price is its net asset value (NAV) per share, which is the fund’s net assets divided by the number of its shares outstanding. Orders received by a fund in good order at or prior to the close of the fund (generally 4:00 p.m. Eastern time) will be executed at the next share price calculated that day.

If you place an order through your Schwab account or an account at another intermediary, please consult with your intermediary to determine when your order will be executed. Generally, you will receive the share price next calculated after a fund receives your order from your intermediary. However, some intermediaries, such as Schwab, may arrange with a fund for you to receive the share price next calculated after your intermediary has received your order. Some intermediaries may require that they receive orders prior to a specified cut-off time.

In valuing underlying fund investments, the funds use the NAVs reported by the underlying funds. The funds’ other portfolio securities are valued using market quotations or official closing prices if they are readily available. In cases where market quotations are not readily available or the investment adviser deems them unreliable, the funds’ portfolio securities are valued based on fair values developed following procedures approved by the funds’ Board of Trustees. The Board of Trustees has designated the investment adviser as the valuation designee (Valuation Designee) for the funds to perform the fair value determination relating to all fund investments.

Shareholders of a fund should be aware that because foreign markets are often open on weekends and other days when the fund is closed, the value of the fund’s portfolio may change on days when it is not possible to buy or sell shares of the fund.

Additional Policies Affecting Your Investment

Each Fund Reserves Certain Rights, Including the Following:

•

To materially modify or terminate the exchange privilege upon 60 days’ written notice to shareholders.

​

•

To change or waive the fund’s investment minimums.

​

•

To suspend the right to sell shares back to the fund, and delay sending proceeds, during times when trading on the NYSE is restricted or halted, or otherwise as permitted by the SEC.

​

•

To withdraw or suspend any part of the offering made by this prospectus.

Options for Fund Distributions

Choose an option for fund distributions. When placing orders through an intermediary, you will select from the options for fund distributions provided by your intermediary. You should consult with your financial intermediary to discuss available options.

Payments by the Investment Adviser or its Affiliates

Schwab Monthly Income Funds | Investing in the Funds35​

are separate from, and may be in addition to, any shareholder service fees or other administrative fees the funds may pay to those intermediaries. The investment adviser or its affiliates also make payments out of their own resources, or provide products and services at a discount, to certain financial intermediaries in connection with certain intermediary activities or services which may facilitate, directly or indirectly, investment in the funds. These payments may relate to marketing and/or fund promotion activities and presentations, educational and/or reporting systems, data analytics and support, or making shares of the funds available for their customers. These payments, which may be significant, are paid by the investment adviser or its affiliates out of their own resources and not from the assets of the funds.

Payments to a financial intermediary may create potential conflicts of interest between the intermediary and its clients as the payments may provide such intermediary with an incentive to favor sales of shares of the funds over other investment options they make available to their customers. Please see the SAI for additional information.

Shareholder Servicing Plan

The Board of Trustees has adopted a Shareholder Servicing Plan (the Plan) on behalf of the funds. The Plan enables the funds to bear expenses relating to the provision by financial intermediaries, including Schwab (together, service providers), of certain account maintenance, customer liaison and shareholder services to the current shareholders of the funds. The funds are not subject to any fee under the Plan.

Policy Regarding Short-Term or Excessive Trading

The funds are intended for long-term investment and not for short-term or excessive trading (collectively market timing). Market timing may adversely impact the funds’ performance by disrupting the efficient management of the funds, increasing fund transaction costs and taxes, causing the funds to maintain higher cash balances, and diluting the value of the funds’ shares.

To discourage market timing, the funds’ Board of Trustees has adopted policies and procedures that are reasonably designed to reduce the risk of market timing by fund shareholders. Each fund seeks to deter market timing through several methods. These methods may include fair value pricing and trade activity monitoring. Fair value pricing is discussed more thoroughly in the subsequent pages of this prospectus and is considered an element of the funds’ policy regarding short-term or excessive trading. Trade activity monitoring is risk based and seeks to identify patterns of activity in amounts that might be detrimental to the funds. Certain trading activity will not be treated as short-term or excessive trading, such as transactions involving in-kind purchases or redemptions of shares of a fund.

The funds and their service providers maintain risk-based surveillance procedures designed to detect market timing in fund shares in amounts that might be detrimental to the fund. Under these procedures, the funds have requested that service providers to the funds monitor transactional activity in amounts and frequency determined by each fund to be significant to the fund and in a pattern of activity that potentially could be detrimental to the fund. Generally, excessive trading activity in a fund is measured by the number of roundtrip transactions in a shareholder’s account. A roundtrip transaction occurs when a shareholder completes a purchase of shares and then sells the same fund’s shares (including exchanges). If an investor engages in multiple roundtrips in a fund within a 60-day period or the fund, in its sole discretion based on these or other factors, determines that a shareholder has engaged in market timing, it may refuse to process future purchases or exchanges into such fund by that shareholder for a period of 90 days. Subsequent violations within a 12-month period will be evaluated to determine whether a permanent block is appropriate. These procedures may be modified from time to time as appropriate to improve the detection of market timing and to comply with applicable laws.

If trades are effected through a financial intermediary, each fund or its service providers will work with the intermediary to monitor possible market timing activity. The funds reserve the right to request that the intermediary provide certain shareholder transaction information to the funds and may require the intermediary to restrict the shareholder from future purchases or exchanges in the funds. Transactions by fund shareholders investing through intermediaries may also be subject to the restrictions of the intermediary’s own frequent trading policies, which may differ from those of the funds. Each fund may defer to an intermediary’s frequent trading policies with respect to those shareholders who invest in the fund through such intermediary if the fund determines that the intermediary’s frequent trading policies are reasonably designed to deter transactional activity in amounts and frequency that are deemed to be significant to the fund and in a pattern of activity that potentially could be detrimental to the fund. Shareholders should consult with their intermediary to determine if additional frequent trading restrictions apply to their fund transactions. A 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.

Although these methods are designed to discourage market timing, there can be no guarantee that the funds will be able to identify and restrict investors that engage in such activities. In addition, some of these methods are inherently subjective and involve judgment in their application. Each fund and its service providers seek to make these judgments and applications uniformly and in a manner that they believe is consistent with interests of the fund’s long-term shareholders. The funds may amend these policies and procedures without prior notice in response to changing regulatory requirements or to enhance the effectiveness of the program.

The funds reserve the right to restrict, reject or cancel within a reasonable time, without prior notice, any purchase or exchange order for any reason.

36Schwab Monthly Income Funds | Investing in the Funds

Fair Value Pricing

The Board of Trustees has approved procedures to fair value the funds’ securities when market prices are not “readily available” or are unreliable. For example, a fund may fair value a security when a security is de-listed or its trading is halted or suspended; when a security’s primary pricing source is unable or unwilling to provide a price; when a security’s primary trading market is closed during regular market hours; or when a security’s value is materially affected by events occurring after the close of the security’s primary trading market.

By fair valuing securities whose prices may have been affected by events occurring after the close of trading, the funds seek to establish prices that investors might expect to realize upon the current sales of these securities. This methodology is designed to deter “arbitrage” market timers, who seek to exploit delays between the change in the value of a fund’s portfolio holdings and the net asset value of its shares, and help ensure that the prices at which the fund’s shares are purchased and redeemed are fair and do not result in dilution of shareholder interest or other harm to shareholders.

The Valuation Designee makes fair value determinations in good faith in accordance with the fair value procedures approved by the Board of Trustees. Due to the subjective and variable nature of fair value pricing, there can be no assurance that a fund could obtain the fair value assigned to the security upon the sale of such security. The respective prospectuses for the underlying funds in which the funds invest explain the circumstances in which those funds will use fair value pricing and the effect of fair value pricing.

Methods to Meet Redemptions

Under normal market conditions, each fund expects to meet redemption orders by using holdings of cash/cash equivalents or by the sale of portfolio investments. In unusual or stressed market conditions or as the investment adviser determines appropriate, each fund may borrow through the fund’s bank lines of credit or through the fund’s interfund lending facility to meet redemption requests. Each fund may also utilize its custodian overdraft facility to meet redemptions, if necessary. Each fund also reserves the right to honor redemptions in liquid portfolio securities instead of cash when your redemptions over a 90-day period exceed $250,000 or 1% of the fund’s assets, whichever is less. You may be subject to market risk and you may incur transaction expenses and taxable gains in converting the securities to cash. In addition, a redemption in liquid portfolio securities would be treated as a taxable event for you and may result in the recognition of gain or loss for federal income tax purposes.

Large Shareholder Redemptions

Certain accounts or Schwab affiliates may from time to time own (beneficially or of record) or control a significant percentage of a fund’s shares. Redemptions by these shareholders of their holdings in a fund or large redemptions by several shareholders may impact the fund’s liquidity and NAV. These redemptions may also force a fund to sell securities, which may negatively impact the fund’s brokerage costs and accelerate the realization of taxable income if sales of securities result in capital gains or other income (which particularly would impact shareholders who do not hold their fund shares in an IRA, 401(k) plan or other tax-advantaged investment plan).

Customer Identification and Verification and Anti-Money Laundering Program

Customer identification and verification is part of a fund’s overall obligation to deter money laundering under U.S. federal law. Each fund has adopted an Anti-Money Laundering Compliance Program designed to prevent the fund from being used for money laundering or the financing of terrorist activities. In this regard, the funds reserve the right to (i) refuse, cancel or rescind any purchase or exchange order; (ii) freeze any account and/or suspend account services; or (iii) involuntarily close your account in cases of threatening conduct or suspected fraudulent or illegal activity. These actions will be taken when, in the sole discretion of fund management, they are deemed to be in the best interest of a fund or in cases when the fund is requested or compelled to do so by a governmental or law enforcement authority. If your account is closed at the request of governmental or law enforcement authority, you may not receive proceeds of the redemption if a fund is required to withhold such proceeds.

Federal law requires all financial institutions to obtain, verify and record information that identifies each person who opens an account. When you open your account, you will have to provide your name, address, date of birth, identification number and other information that will allow the funds or your financial intermediary to identify you. This information is subject to verification to ensure the identity of all persons opening an account.

Your financial intermediary is required by law to reject your new account application if the required identifying information is not provided. Your financial intermediary may contact you in an attempt to collect any missing information required on the application, and your application may be rejected if they are unable to obtain this information. In certain instances, your financial intermediary is required to collect documents which will be used solely to establish and verify your identity.

Each fund reserves the right to close and/or liquidate your account at the then-current day’s price if the fund or your financial intermediary is unable to verify your identity. As a result, you may be subject to a gain or loss on fund shares and will be subject to corresponding tax consequences.

Schwab Monthly Income Funds | Investing in the Funds37​

Distributions and Taxes

Any investment in a fund typically involves several tax considerations. The information below is meant as a general summary for U.S. citizens and residents. Please see the funds’ SAI for additional information. Because each person’s tax situation is different, you should consult your tax advisor about the tax implications of your investment in a fund. You also can visit the Internal Revenue Service (IRS) website at www.irs.gov.

As a shareholder, you are entitled to your share of the dividends and gains your fund earns. Every year, each fund distributes substantially all of its net investment income and net capital gains, if any, to all shareholders of record. These distributions are typically paid at the end of each month. To receive a dividend distribution, you must be a registered shareholder on the date that dividends are declared. Dividend distributions are paid to shareholders on the payable date. Although it cannot be guaranteed, the Income Payout Fund does not expect to make distributions that will be treated as return of capital. The Target Payout Fund and Flexible Payout Fund may make distributions that are treated as a return of capital. Each fund may make an additional distribution at the end of the year in order to comply with applicable law. This additional distribution may include an income component that may be higher or lower than a fund’s regular monthly income payment. The funds expect to distribute their net capital gains, if any, in December to all shareholders of record. During the fourth quarter of the year, typically in early November, an estimate of each fund’s year-end capital gains distribution, if any, may be made available on the fund’s website at www.schwabassetmanagement.com. At the end of the year, the funds may be required under applicable law to recharacterize distributions for the year among ordinary income, capital gains, and return of capital (if any) for purposes of tax reporting to shareholders.

Unless you are investing through an IRA, 401(k) or other tax-advantaged account, your fund distributions generally have tax consequences. Each fund’s net investment income and short-term capital gains are distributed as dividends and will be taxable as ordinary income or qualified dividend income. Qualified dividend income is currently taxed at the reduced maximum rates applicable to long-term capital gains. Other capital gains distributions are taxable as long-term capital gains, regardless of how long you have held your shares in the fund. The maximum individual rate applicable to “qualified dividend income” and long-term capital gains is generally either 15% or 20%, depending on whether the individual’s income exceeds certain threshold amounts. Distributions generally are taxable in the tax year in which they are declared, whether you reinvest them or take them in cash.

If a fund’s distributions exceed its taxable income and capital gains realized during a taxable year, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution will not be taxable to the extent of a shareholder’s adjusted basis but will reduce such basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. To the extent a return of capital distribution exceeds a shareholder’s adjusted basis, the distribution will be treated as gain from the sale of shares, if the shareholder holds shares of the Fund as capital assets. Shareholders who receive periodic distributions consisting of a return of capital may be under the impression that they are receiving net profits when they are not. Return of capital reduces your cost basis in the fund’s shares and is not taxable to you until your cost basis has been reduced to zero. A return of capital is a distribution from the shareholder’s investment principal, rather than net profits from the fund’s returns.

Generally, any sale or exchange of your shares is a taxable event. For tax purposes, an exchange of your shares for shares of another Schwab Fund is treated the same as a sale. An exchange between classes within a fund is not reported as a taxable sale. A sale may result in a capital gain or loss for you. The gain or loss generally will be treated as short term if you held the shares for one year or less, long term if you held the shares longer. The maximum rate is generally either 15% or 20%, depending on whether the individual’s income exceeds certain threshold amounts. Any loss realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, to the extent of any long-term capital gains distributions received (or deemed received) by you with respect to the shares. All or a portion of any loss realized upon a taxable disposition of shares will be disallowed if you purchase other substantially identical shares within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

An additional 3.8% Medicare tax is imposed on certain net investment income (including ordinary dividends and capital gains distributions received from a 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 a threshold amount.

At the beginning of every year, each fund provides shareholders with information detailing the tax status of any distributions the fund paid during the previous calendar year. Schwab customers also receive information on distributions and transactions in their monthly account statements.

Each fund is required to report to you and the IRS the gross proceeds of fund shares you sell or redeem and also cost basis information for shares purchased on or after January 1, 2012 and sold thereafter. Shareholders can elect their preferred cost basis method, however, in the absence of an election, a fund will use an average cost basis method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments, including investments made prior to January 1, 2012 and sold thereafter.

38Schwab Monthly Income Funds | Investing in the Funds

If you are investing through a taxable account and purchase shares of a fund just before it declares a distribution, you may receive a portion of your investment back as a taxable distribution. This is because when a fund makes a distribution, the share price is reduced by the amount of the distribution. You can avoid “buying a dividend,” as it is often called, by finding out if a distribution is imminent and waiting until afterwards to invest. Of course, you may decide that the opportunity to gain a few days of investment performance outweighs the tax consequences of buying a dividend.

A fund may be required to withhold U.S. federal income tax on all taxable distributions and redemption proceeds payable to shareholders if the shareholders 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% (unless a lower treaty rate applies) on amounts treated as ordinary dividends from the fund, as discussed in more detail in the SAI. Furthermore, the funds are required to withhold U.S. tax (at a 30% rate) on payments of taxable dividends made to certain non-U.S. entities that fail to comply (or be deemed compliant) with extensive reporting and withholding requirements designed to inform the U.S. Department of the Treasury of U.S.-owned foreign investment accounts. Shareholders may be requested to provide additional information to the funds to enable the funds to determine whether withholding is required.
