CSS LLC/IL

About CSS LLC/IL

CSS LLC/IL appears in U.S. regulatory filings primarily as an investment vehicle and significant shareholder rather than as a single operating executive with a conventional corporate biography. SEC records place the entity in Chicago, Illinois, and show that it has repeatedly been identified as a large beneficial owner—often above the 10% or 5% thresholds—in several exchange-listed closed-end funds, including Cohen & Steers MLP Income & Energy Opportunity Fund and Duff & Phelps Select MLP & Midstream Energy Fund Inc. More recent filings also show a meaningful position in Total Return Securities Fund. Based on these public records, CSS LLC/IL can be described as an active institutional investor with a recurring presence in the ownership and governance landscape of U.S.-listed investment companies. Its most notable role, from the standpoint of public disclosures, is therefore that of a major shareholder and institutional investor. The available public information does not allow one to confidently assign CSS LLC/IL a single operating title such as Chief Executive Officer or Chief Financial Officer, nor does it support a detailed individual career biography. What the filings do establish is a sustained involvement with investment companies focused on MLPs, midstream energy assets, and income-oriented strategies. That profile suggests expertise in portfolio allocation, closed-end fund analysis, capital structure monitoring, and governance awareness within specialized listed investment products. The available documents do not identify specific management decisions made by the entity, so it is best to stay generic and avoid unsupported claims. The overall picture is of a sophisticated market participant with a focus on strategic holdings, distributions, and long-term influence in niche investment structures.
