Invesco Rochester New York Municipals Fund Class A (RMUNX) is an open-end mutual fund managed by Invesco Advisers, Inc. that seeks to provide tax-free income through a portfolio primarily consisting of investment-grade New York municipal securities whose interest is exempt from federal, New York State, and New York City personal income taxes; the fund invests at least 80% of its net assets in such tax-exempt securities, including revenue bonds (such as dedicated tax, airport, higher education, tobacco settlement, toll road, hospital, transportation, and water/sewer bonds), general obligation bonds, and up to 25% in below-investment-grade municipal obligations; it also employs inverse floating rate securities via tender option bond trusts for leverage and may invest in securities from U.S. territories like Puerto Rico, up to one-third borrowing for investment purposes, and derivatives for hedging or exposure. Launched on May 15, 1986 as part of the former Oppenheimer Rochester Funds and reorganized under Invesco following the 2019 acquisition of OppenheimerFunds by Invesco Ltd. for approximately $5.7 billion in stock, the fund operates within the Muni New York Long category, targeting high-net-worth individuals and taxable investors seeking state-specific tax-exempt income with a focus on preservation of capital alongside income generation; it features multiple share classes including Class A (with 4.25% front-end load and 1.20% net expense ratio), Class Y, and Class R6, with total net assets exceeding $4 billion as of late 2025 and approximately 600 holdings exhibiting a weighted average maturity of 24 years and option-adjusted duration of 12 years. The fund maintains a dedicated tax-exempt municipal bond strategy emphasizing rigorous credit research across New York issuers, with current portfolio managers including Elizabeth Mossow (since April 2024), Joshua Cooney (since April 2024), Julius Williams (since April 2020), Timothy O'Reilly (since April 2020), and Mark Paris (since June 2019); headquartered in Atlanta, Georgia under Invesco Ltd. (founded 1935), it distributes income monthly and had a 30-day SEC yield of around 4.34% (tax-equivalent 7.33% for top bracket) as of September 2025. Recent developments include refreshed management team additions in 2024 with Mossow and Cooney joining to enhance execution amid evolving interest rate environments and municipal credit dynamics; ongoing portfolio adjustments for relative value in high-yield opportunities within New York's dedicated tax and infrastructure sectors; and sustained Morningstar 4-5 star ratings in its category reflecting strong 10-year risk-adjusted performance leadership, alongside quarterly commentaries highlighting rate volatility navigation and credit quality emphasis through Q3 2025.
