Franklin Municipal Green Bond Fund

Important Legal Information

• Fund dividends are generally subject to state and local income taxes, if any. For investors subject to the alternative minimum tax, a small portion of fund dividends may be taxable. Distributions of capital gains are generally taxable. To avoid the imposition of 28% backup withholding on all fund distributions and redemption proceeds, U.S. investors must be properly certified on Form W-9 and non-U.S. investors on Form W-8BEN.
• Total Returns include change in share price, assume reinvestment of all distributions, and reflect the deduction of fund expenses and applicable fees. Total Returns With Sales Charge: returns reflect the deduction of the stated sales charge. Total returns, distribution rate, and yields reflect any applicable expense reductions, without which the results for those impacted funds would have been lower.
• All investments involve risks, including possible loss of principal. Because municipal bonds are sensitive to interest rate movements, the fund's yield and share price will fluctuate with market conditions. Bond prices generally move in the opposite direction of interest rates. Thus, as prices of bonds in the fund adjust to a rise in interest rates, the fund's share price may decline. Puerto Rico municipal bonds have been impacted by recent adverse economic and market changes, which may cause the fund's share price to decline. Changes in the credit rating of a bond, or in the credit rating or financial strength of a bond's issuer, insurer or guarantor, may affect the bond's value. Some sectors might be more likely to issue green bonds, and events or factors impacting these sectors may have a greater effect on, and may more adversely affect, the fund than they would a fund that does not invest in issuers with a common purpose. Green bonds may not result in direct environmental benefits and the issuer may not use proceeds as intended or to appropriate new or additional projects. The fund may invest a significant part of its assets in municipal securities that finance similar types of projects, such as utilities, hospitals, higher education and transportation. A change that affects one project would likely affect all similar projects, thereby increasing market risk. Impacts on sectors more likely to issue green bonds may have a greater adverse effect on the fund because the fund focuses investments in green bonds.
• Performance data represents past performance, which does not guarantee future results. Current performance may differ from figures shown. Investment return and principal value will fluctuate with market conditions, and you may have a gain or loss when you sell your shares.
• Advisor Class, Class R, Class R6 and Class Z shares are only offered to certain eligible investors as stated in the prospectus. The fund offers multiple share classes, which are subject to different fees and expenses that will affect their performance. Please see the prospectus for details.

Footnotes

1. The fund's 30-Day Standardized Yield is calculated using the net income (interest and dividends) per share earned over a trailing 30-day period (annualized), divided by the fund's share price at the end of that period. It may not equal the fund's actual income distribution rate, which reflects the fund's past dividends paid to shareholders.
2. A statistical measurement of the range of a fund's total returns. In general, a higher standard deviation means greater volatility. Based on the fund's monthly returns over the 3-year period ended as of the date of the calculation.
3. A statistical measurement of a fund's historical risk-adjusted performance. It is calculated by taking a fund's excess return over that of the three-month Treasury bill divided by its standard deviation. Higher values generally indicate better historical risk-adjusted performance. Based on the 3 years ended as of the date of the calculation.
4. Public Offering Price — Purchase price for each share of the fund on a given day. It includes the maximum initial sales charge, if any.
5. Net Asset Value — The amount per share you would receive if you sold shares that day.
