FLMB seeks a high level of current income, free from federal taxes, without the use of leverage. The portfolio relies on Franklin Templetons access and experience in the fixed income markets to select investment-grade municipal securities in which the bond proceeds will be used for projects that promote environmental sustainability. While the portfolio will hold securities of varying maturities, the managers seek to maintain a dollar-weighted average portfolio maturity of 5 to 15 years. FLMB will not invest more than 15% of the fund's assets in a single state. Prior to Aug. 15, 2020, the fund was named Franklin Liberty Municipal Bond ETF. From Aug. 15, 2020, to May 2, 2022, the fund name was Franklin Liberty Federal Tax-Free Bond ETF.
