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 waiver and/or expense reimbursement by management as described above for the 1 Year numbers only.

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.</p></div>Principal Investment Strategies<div><p>Under normal market conditions, the Fund invests predominantly in equity securities of companies that the investment manager believes offer compelling growth opportunities. In selecting securities, the investment manager considers many factors, including historical and potential growth in revenues and earnings, assessment of strength and quality of management, and determination of a company’s strategic positioning in its industry.</p><p>The equity securities in which the Fund invests are predominantly common stock. The Fund may invest in companies of any size, including small and medium capitalization companies. In addition to the Fund’s main investments, the Fund may invest a portion (up to 25%) of its net assets in foreign equity securities, including those located in emerging markets.</p><p>The Fund generally seeks to maintain a portfolio consisting of securities of approximately 20-50 companies. Although the Fund seeks investments across a number of sectors, from time to time, based on economic conditions, the Fund may have significant positions in particular sectors.</p><p>The investment manager is a research-driven, “bottom-up” fundamental investor. The investment manager’s investment approach for the Fund focuses on identifying companies that offer, in its opinion, a compelling trade-off between growth opportunity, business and financial risk and valuation. Key valuation metrics include discounted-cash-flow, absolute and relative price-to-earnings, enterprise value, and sum of the parts, among others.</p></div>Principal Risks<div><p>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.</p><p>Market</p><p>The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. A security's 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 securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>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.</p><p>Growth Style Investing</p><p>Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections. Prices of these companies’ securities may be more volatile than other securities, particularly over the short term.</p><p>Focus</p><p>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.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: 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; 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.; 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; limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and currency exchange rate fluctuations and policies. The risks of foreign investments may be greater in developing or emerging market countries.</p><p>Liquidity</p><p>From time to time, the trading market for a particular security or type of security 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 when necessary to meet the Fund’s liquidity needs or in response to a specific economic event and will also generally lower the value of a security. Market prices for such securities may be volatile.</p><p>Smaller and Midsize Companies</p><p>Securities issued by smaller and midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. 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, smaller and midsize companies may be particularly 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.</p><p>Management</p><p>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.</p></div>Performance<div><p>Because the Fund is new, it has no performance history. Once the Fund has commenced operations, you can obtain updated performance information at franklintempleton.com or by calling (800) DIAL BEN/342-5236. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.</p></div>There is a 1% contingent deferred sales charge that applies to investments of $1 million or more (see "Investments of $1 Million or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge.The investment manager has contractually agreed to waive or assume certain expenses so that common expenses (excluding Rule 12b-1 fees and acquired fund fees and expenses and certain non-routine expenses) for each class of the Fund do not exceed 1.00% until April 3, 2017. In addition, the transfer agent has contractually agreed to waive or limit its transfer agency fees for Class R6 shares of the Fund so that transfer agency fees for that Class do not exceed 0.01% until April 3, 2017. Contractual fee waiver and/or expense reimbursement agreements may not be changed or terminated during the time periods set forth above.Other expenses are based on estimated amounts for the current fiscal year.
