This file tracks reported WARF trends across 129 US BSL CLO managers, with monthly data going back to April 2013. Select up to ten combinations of managers and vintages from the dropdown menus, and the chart will instantly compare their WARF levels against one another.
A sample of 580 EU CLO deals (vintage 2013–1H 2025) is included in this study. Deals with a collateral pool factor below 60% are excluded. 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). MVOC is a key point-in-time metric for valuing CLO-rated tranches, widely tracked by participants in both primary and secondary markets.

In the table below, the relative standing of each US CLO manager is illustrated based on their latest average total alpha metrics. A score of 91% means that the manager's total return alpha is at the 91st percentile, indicating that their total return alpha metric is higher than 91% of their peers.
This study underscores the significant divergence in investment performance between the top and bottom 10 US CLO managers based on their alpha. The findings emphasize the critical role of effective manager selection in achieving favorable results. While metrics like par build and weighted average price offer insights, they don't tell the whole story. Conversely, the average WAS, WARF, and liquidity depth metrics for both groups show minimal variance, indicating a limited correlation of these metrics with investment performance based on this sample.
The top five US CLO managers for each WARF category are typically larger managers with a CLO AUM of $8 billion or more.
