Franklin International Small Cap Fund

Investment Goal

Long-term capital appreciation.

Fees and Expenses of the Fund

These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $50,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 52 in the Fund's Prospectus and under “Buying and Selling Shares” on page 43 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A - "Intermediary Sales Charge Discounts and Waivers" to the Fund's prospectus.

Please note that the tables and examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or Advisor Class shares.

Shareholder Fees

(fees paid directly from your investment)

Annual Fund Operating Expenses

(expenses that you pay each year as a percentage of the value of your investment)

^1. Management fees of the Fund have been restated to reflect current fiscal year fees as a result of a decrease in the Fund’s contractual management fee rate effective on May 1, 2021. If the management fees were not restated to reflect such decrease in fees, the amounts shown above would be greater. Consequently, the Fund’s total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights.

^2. Class A and C distribution and service (12b-1) fees have been restated to reflect the maximum rate approved by the board of trustees. Consequently, the total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights due to a different 12b-1 fee rate paid in the Fund’s most recent fiscal year.

^3. The fee waiver and/or expense reimbursement above has been updated to reflect that the investment manager has contractually agreed to waive or assume certain expenses so that operating expenses (excluding Rule 12b-1 fees, acquired fund fees and expenses and certain non-routine expenses) for each class of the Fund do not exceed 1.05% until November 30, 2022. During its term, this fee waiver and expense reimbursement agreement may not be terminated or amended without approval of the board of trustees except to add series and classes, to reflect the extension of termination dates or to lower the cap on Fund’s fees and expenses (which would result in lower fees for shareholders).

^4. The transfer agent has been updated to reflect that the investment manager has contractually agreed to limit its fees on Class R6 shares to 0.03% until November 30, 2022. During its term, this fee waiver and expense reimbursement agreement may not be terminated or amended without approval of the board of trustees except to add series and classes, to reflect the extension of termination dates or to lower the cap (which would result in lower fees for shareholders).

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These

costs, which are not reflected in 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 114.68% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets in a diversified portfolio of marketable equity and equity-related securities of smaller international companies. Smaller international companies are companies with market capitalizations not exceeding (i) $5 billion or the equivalent in local currencies or (ii) the highest market capitalization in the Morgan Stanley Capital International (MSCI) Europe, Australasia, Far East (EAFE) Small Cap Index, whichever is greater, at the time of purchase. The equity securities in which the Fund primarily invests are common stock.

The Fund may invest a portion of its assets in emerging markets securities and may, from time to time, have significant investments in a particular sector or country, such as industrials.

The portfolio managers employ a quantitative screening process to identify stocks believed to be under-valued and a fundamental analysis process to highlight stocks that the portfolio managers believe will appreciate in the long term. The quantitative screening process involves analysis of a company’s financials including, but not limited to, current price-to-equity, price-to-book-value, and price-to-cash-flow ratios as compared to its historical averages, the company’s sector’s historical averages and the relevant country’s historical averages, while focusing on a company’s longer term outlook. For purposes of the Fund’s investment strategies, techniques and risks, the term “investment manager” includes the sub-advisor.

Principal Risks

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the

issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

The current global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, volatility in consumer demand for certain products, defaults and credit ratings downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic is unpredictable and may adversely affect the Fund’s performance.

Stock prices tend to go up and down more dramatically than those of debt securities. A slower-growth or recessionary economic environment could have an adverse effect on the prices of the various stocks held by the Fund.

Foreign Securities (non-U.S.) Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

Regional Focus Because the Fund may invest at least a significant portion of its assets in companies in a specific region, including Europe, the Fund is subject to greater risks of adverse developments in that region and/or the surrounding regions than a fund that is more broadly diversified geographically. Political, social or economic disruptions in the region, even in countries in which the Fund is not invested, may adversely affect the value of investments held by the Fund. Current uncertainty concerning the economic consequences of the January 31, 2020 departure of the United Kingdom from the European Union (EU) may increase market volatility.

Liquidity From time to time, the trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

Emerging Markets The Fund’s investments in emerging market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Small and Mid Capitalization Companies   Securities issued by small and mid capitalization companies may be more volatile in price than those of larger companies and may involve additional risks. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development, and limited or less developed product lines and markets. In addition, small and mid capitalization companies may be affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.

Focus To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.

Industrials Companies The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, these companies are at risk for environmental damage and product liability claims. Companies in this sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of export or import controls, increased competition, depletion of resources, technological developments and labor relations.

Management The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Performance

The following bar chart and table provide some indication of the risks of investing in the Fund. The bar chart shows changes in the Fund's performance from year to year for Advisor Class shares. The table shows how the Fund's average annual returns for 1 year, 5 years, 10 years or since inception, as applicable, compared with those of a broad measure of market performance. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. You can obtain updated performance information at franklintempleton.com or by calling (800)DIAL BEN/342-5236.

Sales charges are not reflected in the bar chart, and if those charges were included, returns would be less than those shown.

Advisor Class Annual Total Returns

Average Annual Total Returns

(figures reflect sales charges)

For periods ended December 31, 2020

The figures in the average annual total returns table above reflect the Class A shares maximum front-end sales charge of 5.50%. Prior to September 10, 2018, Class A shares were subject to a maximum front-end sales charge of 5.75%. If the prior maximum front-end sales charge of 5.75% was reflected, performance for Class A shares in the average annual total returns table would be lower.

Historical performance for Class A, Class C and Class R shares prior to their inception is based on the performance of Advisor Class shares. Class A, Class C and Class R performance has been adjusted to reflect differences in sales charges and 12b-1 expenses between classes.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Advisor Class and after-tax returns for other classes will vary.

Payments to Broker-Dealers and
Other 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 intermediary and your salesperson to recommend the Fund over another investment. Ask your financial advisor or visit your financial intermediary's website for more information.
