Overview

Overview

Why Invest in This Fund?

 

  • Actively managed diversified portfolio of intermediate-term investment grade municipal bonds with an average maturity of three to ten 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 fund 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.

Investment Objective

The fund’s goal is to provide investors with as high a level of current income exempt from federal individual income tax as is consistent with preservation of capital. The fund also seeks to reduce share price volatility compared to longer-term bond portfolios.

Investment Approach

The fund is an actively managed diversified portfolio of municipal bonds. The investment team 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 to manage duration, hedge against interest rate fluctuations and limit taxable events.
