Thornburg Intermediate Term Municipal SMA

Strategy Overview
The Intermediary Term Municipal Strategy is an actively managed diversified portfolio of municipal bonds with an average maturity of three to 10 years and average duration range of 4.5 to 5.5 years. All bonds are investment grade at time of purchase. The strategy applies a relative value framework, focusing on fundamentals and valuations to identify inefficiencies in the market. Team members are responsible for credit research, portfolio construction, trading and risk oversight and have the flexibility to source ideas across sector, geography and issuer. The strategy maintains exposure across the maturity spectrum in order to manage duration, hedge against interest rate fluctuations, and limit taxable events.

Overview

Why Invest in This Strategy?

  • Actively managed diversified portfolio of intermediate-term investment grade municipal bonds with an average maturity of three to 10 years and duration of four to six years.
  • Proven bottom-up fundamental approach that incorporates a top-down macroeconomic overlay to identify what we perceive to be the most attractive opportunities on a relative value basis across geographic regions, sectors, issuers and revenue streams.
  • Relative value philosophy that seeks to maximize tax-exempt income while minimizing changes in its share value. The strategy focuses on identifying attractive value in the investment-grade municipal bond market. We apply a strict discipline of fundamental credit research and strive to produce an attractive dividend while avoiding the long maturities that are most vulnerable to interest-rate swings.
