With a diverse portfolio of over 2,000 holdings and net assets exceeding $5.8 billion as of mid-2025, it aims for consistent long-term performance using a risk-aware, research-driven investment process led by a seasoned management team. The fund’s strategy provides investors with a tax-advantaged income stream, making it significant for those seeking municipal bond exposure and tax efficiency in their fixed-income allocations. It distributes income monthly and is guided by the Bloomberg Municipal Bond Index as its benchmark, supporting both individual and institutional investors in achieving stable income and potential capital appreciation within the broader municipal bond market.
