2025 is on course to be another record-breaking year. This article explores some of the key ingredients behind strong primary issuance.

Among the top performers are Oak Hill Advisors, UBS AM, and Palmer Square Capital Management.

In year-to-date 2025 and throughout 2024, managers have, on average, broadly tracked the loan index across all three inception-to-date annualised metrics: total return, market value (MV) return, and interest return. The benchmark loan index used is the Morningstar LSTA U.S. B/BB Ratings Loan Index. Nonetheless, several managers—such as OHA, Golub Capital, and UBS AM—have continued to distinguish themselves with above-average inception-to-date alpha since 2020, while others have consistently lagged behind the index.

Late last week, approximately $240 million of long-dated AAA tranches (with reinvestment periods ending between 2029-2030) changed hands, as shown in the table below. Top-tier prints were mainly in the 150 DM area. For example, MAGNE 2024-42A A1 traded with a cover bid of 150 DM.

A more objective way to evaluate a manager’s capability is by examining the inception-to-date gross annualised collateral return of their deals, measured relative to the relevant loan indices and assessed on an unlevered basis. This provides a clearer measure of true alpha generation.

How Have EU CLO Managers Stacked Up Against the Loan Index Since Inception? This study examines the long-term performance of 218 EU CLO deals from the 2015–2019 vintages, using the Morningstar European Euro-Denominated Loan Index as the benchmark. As of 19 March 2025, EU CLO managers, on average, had outperformed the loan index on an inception-to-date basis—driven primarily by principal value return outperformance—while their interest return remained broadly in line with that of the index.

According to independent analysis by CLO Research, Generate Advisors has consistently delivered outperformance against the Morningstar LSTA U.S. B/BB Ratings Loan Index on an unlevered basis in recent years. Here’s a set of interview questions from CLO Research, accompanied by responses from Rizwan Akhter, Head of Generate Advisors.

According to CLO Research’s independent analysis, RRAM has delivered consistently robust results from both equity and debt perspectives. Here’s a set of interview questions from CLO Research, accompanied by responses from Bhavin Patel, Chief Investment Officer of Redding Ridge Europe.

The table presented in this premium article showcases the trends by displaying the average annual prepayment rates for the first, second, and third years for each manager. These rates are calculated from seasoned deals whose reinvestment periods concluded before April 2024.

CLO equity investors generally prefer slower prepayment rates in the early years after the reinvestment period, as this helps sustain favourable leverage within the structure and supports more efficient funding costs. Moreover, it provides equity investors with additional time to assess the optimal call timing, which has proven particularly valuable in today’s robust market environment. For instance, a deal that exited its reinvestment period in 2022 and experienced a very rapid post-reinvestment period annual prepayment rate, leading to significant deleveraging, would have been under greater pressure to be called at a time when market conditions were less favourable than they are today.

Can AUM Growth and Performance Go Hand in Hand?

According to CLO Research’s independent analysis, Golub Capital has delivered consistently strong results from an investment alpha perspective. Specifically, Golub Capital has achieved substantial outperformance relative to the Morningstar LSTA U.S. B/BB Ratings Loan Index on an unlevered basis over the past several years. Below is a list of interview questions from CLO Research, along with responses from Scott M. Morrison, Managing Director and Head of Broadly Syndicated Loans.

Have you ever wondered how CLO tranche ratings—AAA, AA, A, BBB, and BB—are derived from a portfolio of non-investment grade loans?

Drawing from a sample of 87 EU CLO deals that have either been redeemed or are expected to reach full redemption shortly, equity tranches from the 2020, 2022, and 2023 vintages have delivered notable final IRRs, underpinned by robust equity NAV metrics. As illustrated in the table, their average equity NAVs surpassed 100%, underscoring strong performance.

Although every CLO deal is unique, analysing historical prepayment rates during the post-RP period is valuable. It reveals manager tendencies, distinguishing those who consistently deliver lower prepayment rates from those with higher rates.

A sample of 496 EU CLO deals (vintage 2013–2023) 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 crucial point-in-time metric for pricing CLO-rated tranches, closely monitored by primary and secondary market participants.

While each CLO deal is different, understanding the historical prepayment rates based on the original collateral balance during the post-RI period for each manager remains highly beneficial. Analyzing these rates offers insights into the tendencies of different managers, highlighting those who consistently achieve lower prepayment rates and those who tend to experience higher rates in the post-reinvestment phase. To illustrate these trends, the following table presents the average first-year, second-year, and third-year annualized prepayment rates for each manager, based on data from their seasoned deals that have passed their reinvestment end dates. These historical post-RI prepayment rates could be useful as cash flow modeling inputs for each manager.

Based on 558 post-2012 US CLO deals that have been redeemed or paid off so far, those from the 2014 and 2018 vintages performed the worst. However, the sample size for the 2018 vintage deals is still relatively small. Deals from the 2020 and 2022 vintages performed the best, with median deals registering IRRs of...

YTD, 70 BSL CLO deals have been reported to have undergone resets. Among these, 15 deals from the 2022–2023 vintages have reduced their cost of funding by an average of 61 bps, while also extending their reinvestment periods by about 2.7 years on average. 

The table below shows the top-performing managers with the most 2013–2019 deals that are in the 90th percentile category. Notably, CSAM stood out as the most successful and consistent manager in delivering good returns to equity investors. Other successful managers include Oak Hill Advisors, KKR Financial Advisors, Goldentree Asset Management, Neuberger Berman, Generate Advisors, Fortress Investment Group, and Anchorage Capital Group.

At first glance, one might assume that managers with higher portfolio spreads tend to perform well during favorable market conditions but struggle during downturns. However, upon closer analysis of the average alpha performance within each category, this assumption is only partially valid and not universally applicable.

A sample of 313 seasoned deals (2016–2019 vintage deals) managed by 57 US CLO managers is included in this study. The benchmark loan index used is the Morningstar LSTA US B-BB Ratings Loan Index.

This study includes a sample of 93 more recent deals (closed in 2021 and Jan 2022) managed by 46 managers, using the Morningstar European B Ratings Loan Index as the benchmark loan index. The table below illustrates the relative standing of each EU CLO manager based on their latest average total alpha metrics (as of 26th June 2023) . A score of 98%, for instance, indicates that the manager’s total return alpha is at the 98th percentile, meaning their total return alpha metric exceeds that of 98% of their peers.

Overweight indicates that the manager’s average industry exposure exceeds the sample average exposure by 1 percentage point. Conversely, underweight means the manager’s average industry exposure is less than the industry average exposure by 1 percentage point.
