This study is based on a sample of 1,600 U.S. BSL CLO deals. Static deals are excluded from the analysis.

In the US BSL CLO market, 12 and 27 managers offer average pairwise overlap levels of below 50% across their optimal five-deal and three-deal combinations, respectively. The table below presents the average pairwise overlap for these optimal combinations by manager.

Is it possible to achieve low overlap among three deals from the same EU CLO manager? In the EU CLO market, 18 managers offer an average pairwise overlap of less than 50% across their optimal three deals.

AAA/AA investors are always thinking about systemic risks, and one way to reduce this risk is to minimise overlap exposure within their portfolios. The beauty of this model is that users can choose from a pool of CLO deals managed by managers they favour and optimise the portfolio for the lowest possible overlap risk based on the target number of positions they are looking to hold. Please find the download link below for the overlap optimisation model, which allows users to select from a pool of US BSL CLO deals to be added to an existing portfolio, with the model identifying the optimal outcome from an overlap perspective.

A sample of 542 EU CLO deals is used in this study. Called deals and static deals are excluded from the sample. Among the 54 managers with at least three deals in the sample, Bridgepoint Credit, Napier Park Global, RRAM and UBS AM stand out.

A sample of 414 deals from the 1Q 2020–2Q 2025 vintages is used, excluding static deals and those with a collateral factor below 0.80. Each deal’s underlying collateral weighted average spread (WAS) is adjusted for its weighted average price (WAP) as of 1 May 2026. The adjusted WAS also takes par losses into account.

The term WAS, or Weighted Average Spread, refers to a key metric used to assess the risk associated with the underlying collateral of a CLO. In general, a higher WAS may indicate a riskier collateral pool, as some CLO managers may seek higher-yielding but potentially riskier investments in order to achieve arbitrage. What is important is to adjust the collateral WAS for loan prices as well as par losses. The adjusted WAS is a very useful metric for senior CLO tranche investors when pricing senior tranches. For example, all else being equal, AAA investors would typically demand a higher spread if the underlying collateral WAS is higher after adjusting for portfolio prices and par losses. AAA investors tend to be less concerned about idiosyncratic risks and more focused on systemic risks. A materially wider collateral WAS may therefore imply a higher probability of credit losses. A sample of 334 deals from the 2024 vintage is used, excluding static deals and those with a collateral factor below 0.75. Each deal’s underlying collateral weighted average spread (WAS) is adjusted to reflect its weighted average price (WAP) as of 10 April 2026. The adjusted WAS also incorporates par losses.
