A sample of 554 EU CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 60% are excluded. The MVOC at the BB level is used for the assessment of managers' capital preservation performance because it is less affected by deleveraging than the corresponding MVOC percentiles at the AAA, AA, or single-A levels, making it a more meaningful measure.
A sample of 1,640 US BSL CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 55% are excluded. The MVOC percentile at the BB level is used because it is less affected by deleveraging than the corresponding MVOC percentiles at the AAA, AA, or single-A levels, making it a more meaningful measure of principal preservation.
Recently, CLO Research published an overlap optimisation model covering almost all outstanding US BSL, middle-market and EU CLO deals. Users can use the model to optimise their CLO investment positions and minimise overlap risk.
Below are tables presenting the MVOC (AAA–B) and equity NAV of US BSL and EU CLO deals by vintage, based on asset prices as of 17 July 2026.
