How to Evaluate a Private Credit Manager Before Committing Capital: A Due Diligence Checklist

TL;DR: Private credit defaults hit a record 9.2% in 2025, with small-company loans defaulting at 15.8%. Yet first-lien senior secured lenders recovered at or near par in most cases. The spread between good and bad private credit managers just got very wide. Here is the eight-point framework I use to evaluate a private credit manager before committing capital — and the three red flags that should end the conversation immediately.

According to Fitch Ratings' March 2026 report, the U.S. private credit default rate hit 9.2% in 2025 — the highest level since Fitch began tracking private credit performance. The bifurcation was severe: issuers with EBITDA under $25 million defaulted at 15.8%, while issuers with EBITDA over $100 million defaulted at just 4.0%. The vintage exposure from 2021-2022 : when managers competed aggressively on loose covenant structures and compressed spreads : is where most of the damage concentrated.

The good news: recovery rates held. Despite the elevated default rate, 6 of 8 Fitch-tracked first-lien private credit cases recovered at par. The remaining two recovered at 70-90%. The structure of good lending protected capital even when borrowers restructured.

This is the moment to get rigorous about evaluating managers. Not when defaults are low and every manager looks smart.

The Eight-Point Evaluation Framework

1. Non-Accrual Rate and Trend

Non-accruals are loans where the borrower has stopped paying interest. They are the most leading indicator of portfolio stress available to you before formal default is declared. Any private credit manager you evaluate should be able to tell you their non-accrual rate as a percentage of portfolio fair value : and you should see the trend over the past 8-12 quarters.

A non-accrual rate below 2% of fair value is generally healthy. 2-4% warrants investigation into specific credits. Above 4%, ask hard questions about credit selection and monitoring discipline.

2. Track Record Attributable to the Current Team

This is where many manager presentations mislead. A fund marketing a 12% net IRR since 2015 sounds compelling : until you realize the current managing partners joined in 2020 and the historical returns were generated by a team that is no longer present. Private credit returns are manager-specific. The team writes the loans. If the team changed, the track record is not fully attributable.

Ask: which specific deals are attributable to the current decision-makers? What were their personal responsibilities on those deals? What credit decisions did they make independently versus as part of a committee at a prior employer?

3. Origination Sourcing: Where Do the Deals Come From?

Direct lending is a sourcing business. Managers who originate primarily through brokers are paying for deal flow and competing in an auction market where pricing is tight. Managers who source directly through proprietary relationships : intermediary relationships built over years, referral networks, non-sponsored direct origination : pay less for deal flow and often see better terms.

Ask the manager: what percentage of deals come from proprietary vs. broker-originated sources? What is the spread differential between your proprietary sourcing and brokered deals? If they cannot answer this question with data, they are probably a broker-dependent lender competing on price in a crowded auction market.

4. Covenant Package and Underwriting Discipline

Covenant-lite loans : loans that eliminate or weaken maintenance covenants, removing the lender's early warning system when a borrower deteriorates : were a major driver of the 2025 default cycle damage. Cliffwater's CDLI data shows that its since-inception annualized return is 9.53% : but that average masks significant variance by manager quality and vintage.

Ask the manager: what percentage of your current portfolio has maintenance covenants? What is the average leverage multiple of your portfolio companies (net debt/EBITDA)? What is your minimum DSCR (debt service coverage ratio) requirement at underwriting? Managers with strong covenant cultures will answer these questions immediately and with confidence.

5. Manager Registration and Form ADV

Any private credit manager with more than $100 million in assets is required to register with the SEC as an investment adviser. That registration is publicly available via the SEC's IAPD (Investment Adviser Public Disclosure) database. Pull the manager's Form ADV Part 2A (the brochure) : it discloses fee structures, conflicts of interest, disciplinary history, and business description.

Red flag: a manager who is not SEC-registered but is managing more than $100M in assets. Red flag: a Form ADV showing undisclosed compensation arrangements or multiple affiliated entities with opaque fee structures. This public document is free. Read it.

6. Portfolio Concentration and Sector Exposure

A private credit portfolio with 20% exposure to one sector or one borrower is not diversified : it is a concentrated bet wearing diversification clothing. Ask for a breakdown of the portfolio by sector, geography, borrower size, and single-obligor concentration.

Sensible limits: no single obligor exceeding 5% of portfolio fair value, no single sector exceeding 25-30%, no single vintage cohort (year of origination) exceeding 40%. Managers who cannot produce this data on demand do not have the portfolio analytics infrastructure to manage credit risk professionally.

7. Loss-Adjusted Yield and Net Return History

Gross yield means nothing without understanding realized losses. A manager generating 13% gross yield but experiencing 3% annualized credit losses is delivering 10% gross and much less after fees. A manager generating 10% gross yield with 0.5% credit losses is delivering 9.5% gross with much less blowup risk.

Per Cambridge Associates private credit benchmarks, the top-quartile direct lending funds have generated net IRRs of 10-14% over 10-year periods while loss rates remain below 1% annually. Ask managers to show you their realized loss rate : not just their gross yield. If they do not track this separately, that is an answer.

8. LP Reporting Quality and Frequency

How you know if something is going wrong is a function of how much information you receive and how often. Good private credit managers provide: quarterly NAV reports with mark-to-market pricing, portfolio company operating updates (revenue, EBITDA, coverage ratios) at least annually, detailed non-accrual and watch list reports, and responsive communication when portfolio companies miss covenants.

Bad private credit managers provide: quarterly NAV with minimal supporting detail, no watch list disclosure, annual calls where they only discuss the performers, and slow response when you ask about specific credits. Reporting quality is a leading indicator of operational quality. If they manage investor relations carelessly, they probably manage credit carelessness too.

Three Red Flags That End the Conversation

1. Management team continuity broken: More than 30% of the investment team left in the last 24 months, particularly if senior credit professionals departed. Credit is relationship-intensive : relationships are the asset.
2. Vintage concentration in 2021-2022 at covenant-lite terms: Any manager with significant 2021-2022 vintage exposure in covenant-lite structures to sub-$25M EBITDA companies deserves aggressive questions about current portfolio health.
3. Undisclosed conflicts in the GP/LP relationship: Management fees charged on committed capital rather than invested capital from Day 1, undisclosed related-party transactions, GP co-investment on sweetheart terms not available to LPs. Pull the Form ADV. Ask about every line item.

Frequently Asked Questions

What is the Cliffwater Direct Lending Index (CDLI) and how do I use it?

The CDLI is the primary benchmark index for U.S. direct lending, tracking the performance of over 14,000 middle-market loans held by BDCs and other direct lending vehicles. It reports quarterly net returns after estimated fees and credit losses. The since-inception (2004) annualized return is 9.53%. Use it as a baseline: any manager claiming materially better returns over a long period should explain specifically why their credit selection and structuring is differentiated enough to justify the premium claim.

How do I find a private credit manager's SEC registration?

Go to the SEC's Investment Adviser Public Disclosure database at investor.gov/IAPD or sec.gov/iapd. Search by firm name or CRD number. Pull Part 2A of their Form ADV (the brochure) and Part 2B (the supplement for key individuals). The document discloses fees, disciplinary history, conflicts of interest, business description, and key personnel biographies. This is free, public, and mandatory reading before any LP commitment.

What minimum investment is required for private credit funds?

It varies widely by structure. Publicly traded BDCs have no minimum beyond the share price ($10-$30 typically). Non-traded BDCs minimum investments range from $2,500 to $25,000. Interval funds minimums are typically $10,000-$100,000. Direct LP commitments to private credit funds typically start at $250,000 for smaller funds and $1-5 million for institutional-grade managers. Some placement agents aggregate investors into feeder structures at $100,000-$250,000 minimums.

What is a non-accrual loan and why does it matter?

A non-accrual loan is a loan where the borrower has stopped making contractual interest payments and the lender has ceased recognizing interest income on an accrual basis. Non-accrual status typically precedes formal default. When a lender moves a loan to non-accrual, it signals financial stress at the borrower level. Investors should monitor non-accrual rates closely: rising non-accruals over multiple quarters often forecast future realized losses and potential dividend cuts in income-focused vehicles like BDCs.
