Fiduciary/Claymore Energy Infrastructure Fund (NYSE: FMO) is a closed-end management investment company that seeks to provide a high level of after-tax total return with an emphasis on current distributions to shareholders by investing at least 80% of its managed assets in master limited partnership (MLP) entities and at least 65% in equity securities of MLP entities, primarily within the North American energy infrastructure sector; portfolio concentrations include midstream oil, diversified infrastructure, gathering and processing, midstream natural gas, and other energy infrastructure. The Fund, managed by Guggenheim Funds Investment Advisors, LLC with Tortoise Capital Advisors, L.L.C. as sub-adviser, employs financial leverage and may use options on securities, while targeting holdings such as MPLX LP, Plains All American Pipeline, L.P., and Enterprise Products Partners L.P.; it operates as a taxable C-corporation due to MLP concentration, passing through tax-deferred income from MLP distributions. Founded on December 22, 2004 and headquartered in Chicago, Illinois through its investment adviser, FMO primarily serves retail and institutional investors seeking income from energy infrastructure MLPs across the United States and Canada.
In a major strategic reorganization, FMO merged with and into Kayne Anderson Energy Infrastructure Fund, Inc. (NYSE: KYN) effective prior to the NYSE market open on March 7, 2022, following board approval in September 2021 and shareholder consent; FMO shareholders received KYN common shares at an exchange ratio of approximately 1.366 based on relative NAVs as of March 4, 2022, resulting in KYN's post-merger assets of about $2.0 billion and enhanced scale, liquidity, and cost efficiencies while maintaining a focus on energy infrastructure equity investments. This tax-free reorganization consolidated two leading MLP-focused closed-end funds, positioning the combined entity as the largest in the sector without altering KYN's high after-tax total return objective or distribution policy. No significant partnerships, funding rounds, new product launches, or further operational changes have been reported for FMO post-merger, as its independent operations ceased upon completion of the transaction.
