CLO Manager Risk
Manager risk—the risk that a CLO manager makes poor credit decisions, over-trades, or operates with conflicts of interest—is the single largest determinant of CLO equity returns and a meaningful factor even for senior debt. Tier 1 managers outperform Tier 3/4 managers by 300-500 bps in equity IRRs through superior credit selection, timely trading, and crisis management. This guide explains types of manager risk, how to evaluate manager quality, and red flags to avoid.
Why Manager Risk Is the Dominant Variable
Performance Dispersion Is Massive
Equity IRRs by manager quality (2010-2024 average vintages):
- Top quartile (Tier 1): 15.8% IRR
- Second quartile (Tier 2): 13.5% IRR
- Third quartile (Tier 3): 11.2% IRR
- Bottom quartile (Tier 4): 9.5% IRR (some deals < 5% or losses)
Dispersion: 630 bps between top and bottom quartile. Over 10-year CLO life, this compounds to 90% cumulative return difference.
Manager Impact Across Capital Structure
| Tranche | Manager Quality Impact | Metric |
|---|---|---|
| Equity | Extreme (300-500 bps IRR diff) | Direct exposure to defaults and trading decisions |
| BB/B | High (150-300 bps diff) | OC test failures, deferral frequency |
| BBB | Moderate (75-150 bps diff) | Deferral rates, recovery timing |
| A/AA | Low (25-50 bps diff) | Minimal in normal times; matters in crisis |
| AAA | Very Low (10-25 bps diff) | Mostly liquidity/spread; zero defaults either way |
Types of Manager Risk
1. Credit Selection Risk
Definition: Manager picks wrong loans, leading to above-average default rates.
Manifestations:
- Poor underwriting: Failing to identify weak credits (declining EBITDA, overleveraged, industry headwinds)
- Yield chasing: Buying lowest-quality B-/CCC loans to boost spread (4-5% higher default risk)
- Industry concentration: Overweight cyclical sectors (retail, energy) that underperform during downturns
- Late-cycle mistakes: Buying aggressive 2006-2007 vintage loans at peak prices
Impact example:
- Tier 1 manager: 2.5% annual default rate (2010-2024)
- Tier 4 manager: 4.2% annual default rate
- Difference: 1.7% higher defaults per year
- Equity impact: 1.7% × 200 bps sensitivity = 340 bps lower IRR over life of deal
2. Trading Activity Risk
Optimal turnover: 25-40% annually during reinvestment period
Under-trading (< 20% turnover):
- Fails to upgrade portfolio quality as spreads tighten
- Holds deteriorating credits too long (hoping for recovery)
- Misses opportunity to rotate out of cyclicals late-cycle
- Result: Higher default rates, worse OC cushions
Over-trading (> 50% turnover):
- Excessive transaction costs (bid-ask spreads, fees)
- Style drift (moving from defensive to aggressive portfolio mid-cycle)
- Chasing recent performance (buying what's hot, selling what's not)
- Result: 50-150 bps drag on equity returns from transaction costs
3. CCC Management Risk
CLO indentures limit CCC-rated exposure to 5-7.5% of portfolio. How managers use this "bucket" reveals risk appetite:
| Manager Type | CCC Exposure | Rationale | Risk Level |
|---|---|---|---|
| Conservative (Tier 1) | 2-4% | Minimize tail risk; hold CCCs only if high conviction on recovery | Low |
| Balanced (Tier 2) | 4-6% | Some opportunistic CCC buying for yield pickup | Moderate |
| Aggressive (Tier 3) | 6-7.5% | Maximize near-term yield; use full CCC bucket | High |
| Red Flag | 7.5% (at limit) consistently | Yield chasing; ignoring risk | Very High |
CCC default rates: 20-30% annually (vs. 3-5% for B-rated, 0.8% for BB). Using full 7.5% bucket exposes equity to 150-200 bps higher default costs.
4. OC Test Management Risk
Managers who run thin OC cushions face higher risk of test failures (which cease equity distributions):
| Manager Quality | AAA OC Cushion | Test Failure Rate (2008-2024) | Avg Duration of Failure |
|---|---|---|---|
| Tier 1 | 4-7 points above trigger | < 5% | 3-6 months |
| Tier 2 | 2-4 points above trigger | 10-15% | 6-12 months |
| Tier 3 | 0-2 points above trigger | 20-30% | 12-24 months |
| Red Flag | At or below trigger | 50%+ | 24-48 months (or never cure) |
Impact of test failure: Equity distributions cease entirely. If failure lasts 24 months, equity IRR drops 400-600 bps.
5. Conflicts of Interest
Multiple CLO management: Managers running 20-30 CLOs face allocation decisions:
- Best-case: Manager allocates new loans pro-rata across all CLOs
- Gray area: Manager favors flagship/newer CLOs with better loans; older CLOs get lower quality
- Worst-case: Manager "high-grades" certain CLOs (giving best loans) while stuffing others with CCC/distressed
Fee incentive conflicts:
- Senior management fee: Paid before all tranches (20-30 bps on collateral balance). Manager benefits from maintaining collateral balance even if it means holding defaulted loans too long.
- Subordinated fee: Paid after debt but before equity. Manager might prefer actions that protect sub fee over maximizing equity returns.
- Low equity ownership: If manager owns < 5% of equity, incentives not fully aligned with equity holders
6. Operational and Team Risk
Key person risk:
- Many CLO platforms built around single credit expert
- If key PM/CIO departs, performance often deteriorates
- 2015-2019 saw multiple manager spin-outs where teams left to start new firms
Team turnover:
- Stable teams (Tier 1): < 10% annual credit analyst turnover
- High turnover (red flag): > 25% annual turnover signals cultural issues, compensation problems
Operational failures:
- Breaching indenture covenants (industry concentration, obligor limits)
- Failing to report accurately to trustee
- Missing trade windows (inability to sell deteriorating credits quickly)
How to Evaluate Manager Quality
Quantitative Metrics (60% of evaluation)
1. Historical equity IRRs by vintage (30%):
- Compare manager's 2007-2008 vintages to peers (stress test)
- Compare 2010-2013 vintages (post-crisis recovery)
- Consistency across cycles more important than single vintage outperformance
2. Portfolio default rates (20%):
- Manager's default rate vs. industry average (2.5% vs. 3.2% = excellent)
- Defaults during 2008-2009 (7-8% = excellent; 10-12% = poor)
3. OC test track record (10%):
- % of deals that failed OC tests (< 5% = excellent)
- Average cushion maintained above trigger (4-7 points = conservative)
- Speed of curing failures (< 6 months = strong management)
Qualitative Factors (40% of evaluation)
1. Team stability and depth (15%):
- Years in business (10+ years minimum, 15+ preferred)
- Credit team size (20+ analysts for Tier 1)
- Senior team tenure (avg 8+ years = stable)
- Succession planning (clear next generation of leadership)
2. Alignment of interests (10%):
- Manager equity retention (20-50% = strong alignment)
- Fee structure (reasonable vs. excessive)
- Number of CLOs managed (15-30 = sweet spot; > 40 may indicate over-extension)
3. Investment process (10%):
- Documented credit underwriting standards
- Sector expertise (dedicated industry analysts)
- Trade approval process (committee-based vs. single PM)
- Risk management systems (real-time portfolio monitoring)
4. Transparency and access (5%):
- Quarterly investor calls
- Responsiveness to investor inquiries
- Detailed reporting beyond trustee reports
- Willingness to discuss mistakes and lessons learned
Red Flags to Avoid
Quantitative Red Flags
- Bottom quartile IRRs: 2+ consecutive vintages performing below median
- High default rates: > 4% annually over full cycle (vs. 3.2% industry average)
- Frequent OC failures: > 20% of deals failing tests
- Extended failures: OC test failures lasting > 18 months
- Persistent CCC exposure: Consistently at 7-7.5% limit (yield chasing)
- Excessive turnover: > 60% portfolio turnover annually
Qualitative Red Flags
- Team departures: Loss of senior PM or CIO; high analyst turnover (> 25% annually)
- Rapid growth: Doubling AUM in < 2 years (potential quality dilution)
- Style drift: Sudden shifts from conservative to aggressive strategy
- Minimal equity retention: < 5% manager ownership (misaligned incentives)
- Lack of transparency: No investor calls; unresponsive to inquiries
- First-time issuer challenges: Tier 4 managers often underperform first 2-3 deals (learning curve)
- Operational issues: Indenture breaches; late reporting; trustee disputes
Manager Risk Mitigation Strategies
For Equity Investors
1. Manager diversification:
- Invest across 5-10 different managers (reduces single-manager risk)
- Overweight Tier 1 managers (70-80% of capital)
- Limit exposure to Tier 3/4 (< 20% of capital)
2. Vintage diversification:
- Dollar-cost average across multiple years (avoid single vintage concentration)
- Avoid late-cycle vintages (2006-2007, 2018-2019 underperformed)
3. Ongoing monitoring:
- Review monthly trustee reports (OC cushions, CCC %, default rates)
- Attend quarterly manager calls
- Compare performance to peer managers quarterly
- Red flag: OC cushion declining for 2+ consecutive quarters
For Debt Investors (BBB and below)
- Tier 1 only for mezzanine: BBB/BB investors should stick to Tier 1/2 managers (manager quality matters more as you go down capital structure)
- Limit single-manager exposure: < 10% of portfolio in single manager's deals
- Subordination comfort: Ensure sufficient cushion (BBB wants 13-18% subordination; verify manager maintains it)
For AAA Investors
- Manager quality less critical: Zero Tier 1 vs. Tier 3 AAA defaults; difference is liquidity and spread (10-20 bps)
- Diversify anyway: Hold 10-20 different managers for liquidity (Tier 1 AAAs trade better in stress)
- Avoid true outliers: Don't buy AAA from managers with > 30% OC test failure rates (even if AAA unaffected, signals poor management)
2008-2009 Case Study: Manager Quality Mattered
Performance Divergence During Crisis
| Manager Tier | Avg Default Rate (2008-2010) | OC Test Failure % | 2007-2008 Vintage Equity IRR |
|---|---|---|---|
| Tier 1 | 7.8% | 8% | 8-10% |
| Tier 2 | 9.5% | 18% | 5-7% |
| Tier 3 | 11.2% | 32% | 2-5% |
| Tier 4 | 13.5% | 45% | 0-3% (some losses) |
| Industry Avg | 9.8% | 22% | 5-7% |
What separated winners from losers:
- Pre-crisis positioning: Tier 1 managers reduced cyclical exposure (retail, homebuilding) in 2006-2007
- Active trading: Sold deteriorating credits early (Q4 2007 - Q2 2008) before bankruptcies
- Industry expertise: Identified which borrowers would survive recession
- Workout capabilities: Worked with distressed borrowers to maximize recoveries (75-80% vs. 65-70% for weak managers)
- OC management: Maintained 4-7 point cushions entering crisis; avoided test failures
Key Takeaways
- Manager risk is dominant variable: 300-500 bps equity IRR difference between Tier 1 and Tier 3/4
- Key metrics: Default rates (2.5% vs. 3.2% industry), OC test failures (< 5% vs. 20-30%), equity IRRs by vintage
- Optimal turnover: 25-40% annually (< 20% = too passive; > 50% = over-trading)
