Given the significantly smaller base of US MM CLO AUM, it is unsurprising that annual growth has continued to remain in double figures. In contrast, US BSL CLO AUM recorded growth rates of just 3.3% and 4.3% in 2024 and 2023, respectively, both of which were lower than the 9.2% growth rate recorded in 2020.

Please refer to the table below, which displays the trends in 2.0 US BSL CLO AUM for each of the top 100 US BSL CLO managers since 2012. The year-end notional AUM (in billions of dollars) for each period is calculated based on the pricing dates of CLO deals and the notional of the underlying collateral. For a consistent comparison, the AUM figures for each manager have been adjusted for mergers and acquisitions and changes in management contracts. In 2024, 37 of the top 100 managers experienced a decrease in their assets under management. Conversely, Elmwood, AGL, and Onex significantly boosted their assets, each securing more than 10% of the total growth recorded that year. Irradiant captured the largest market share of AUM growth in 2023, with Blackstone leading in 2022 and 2021, and RRAM in 2020.

Market Value Over-Collateralization (MVOC), for instance, at the BB tranche level, is calculated by dividing the collateral market value (MV) by the sum of CLO liabilities (AAA to BB).

On average, EU CLO managers have met the expectations of their equity investors. Overall, based on deals that have already been redeemed or are anticipated to be redeemed, EU CLOs have delivered good performance, with an average equity IRR of 12.4%. This success can be attributed to a combination of factors, including disciplined issuance spurred by risk retention requirements, resets of more seasoned deals such as those from 2014 and 2015, the resilience of the underlying loan performance, the expertise of the managers, favourable CLO liability costs, and attractively priced assets, among others.
