Manager Selection and Due Diligence

Why the Order of Evaluation Matters

Most families encounter a manager through performance — a strong track record shown in a pitch deck or introduced by a consultant. Sophisticated evaluators deliberately reverse that instinct. They examine philosophy, process, and people first, and treat performance as the last piece of evidence, not the first. The reason is straightforward: a strong track record explained by a coherent, repeatable philosophy is meaningful; a strong track record with no clear explanation may be luck, a favorable market environment, or a risk that hasn't yet been realized.

This sequencing shapes the entire evaluation. Questions about returns only become useful once you understand what a manager was trying to do and whether the team has the continuity and skill to keep doing it. An investment committee at a well-structured family office often formalizes this order in its evaluation templates precisely to prevent the natural pull of recent performance from distorting judgment.

Philosophy and Process: The Foundation of the Evaluation

A manager's investment philosophy is the set of beliefs about markets and human behavior that explains why a particular approach should generate returns over time. A philosophy isn't a marketing slogan — it should name a specific market inefficiency or structural advantage the manager believes exists, explain why it persists, and describe how the manager is positioned to exploit it. If a manager cannot articulate this clearly, that itself is informative.

Philosophy is tested against process — the repeatable set of steps used to find, analyze, size, monitor, and exit positions. Key questions include: How is the opportunity set defined and screened? Who has final authority over position decisions? How are position sizes determined, and what are the risk limits? What triggers a sale or an exit? A process that has clear, documented answers to these questions is more likely to produce consistent behavior across market environments than one that depends on a single person's intuition in the moment.

For private fund managers, the evaluation of process extends to sourcing — how deals are found and why they flow to this manager rather than a better-capitalized competitor — and to value creation, the concrete steps taken to improve an asset between acquisition and exit.

People and Organization

Even a compelling philosophy and a well-documented process depend on human beings to execute. Evaluators examine the team across several dimensions.

• Continuity. Has the team that produced the track record actually remained in place? Performance records belong to firms, but returns are generated by people. Significant turnover in senior investment personnel is a material concern.
• Depth. Is the firm dependent on one or two key individuals, or is decision-making distributed across a bench? A key-person provision in a private fund's partnership agreement addresses this legally, but the underlying business question is whether the organization would remain functional if a key individual departed.
• Incentives. How are investment professionals compensated? Does the fee and carry structure (see carried interest) align the manager's economic interest with investors? Are senior people meaningful owners of the business?
• Culture and decision-making. Is dissent welcomed, or does the most senior person's view always prevail? How are mistakes analyzed internally?

Reference checks are an underused tool for answering these questions. Speaking with former employees, co-investors, and — where accessible — former portfolio companies or counterparties often surfaces information that no pitch book contains. Questions should be open-ended: "How did the team handle a difficult situation?" yields more than "Is this a good firm?"

Reading the Performance Record

Once philosophy, process, and people have been assessed, performance analysis can begin in earnest. The primary questions are whether the returns were consistent with the stated approach and whether the risk taken to generate them was appropriate and understood.

Useful dimensions of performance analysis include: returns across different market environments (not just the most favorable period), drawdown behavior during stress, volatility relative to peers and a relevant benchmark, and attribution — which decisions actually drove the results. A manager who outperformed primarily because of a single concentrated bet may not have done so through skill the strategy was designed to replicate.

For private funds, standard metrics such as internal rate of return, multiple on invested capital, and distributions to paid-in capital each capture different aspects of the return. A fund showing high unrealized gains (a high residual value to paid-in) but limited cash returned to investors is a different risk profile than one with similar accounting returns but substantial distributions. Comparing a manager's record against a public market equivalent can put private returns in context. These metrics are covered in detail in the companion article on IRR, MOIC, DPI, and TVPI.

Operational Due Diligence: A Separate Discipline

Operational due diligence (ODD) is the evaluation of a manager's business infrastructure entirely apart from the investment case. Its purpose is to assess whether the firm is well-run enough to be a safe custodian of capital — independent of whether the investment thesis is compelling. Some of the largest losses in investment history have occurred not because a strategy failed, but because the operational infrastructure was fraudulent or simply inadequate.

ODD covers a range of areas:

• Custody and asset verification. Where are assets held, and are they held by an independent custodian? Can the manager produce statements directly from the custodian rather than manager-generated documents?
• Valuation. How are assets valued, especially illiquid ones? Is there an independent administrator or third-party valuation agent, or does the manager mark its own book?
• Compliance and legal. What regulatory registrations does the firm hold? Has it been subject to regulatory actions, investor disputes, or litigation?
• Technology and cybersecurity. How are records maintained, and are controls in place to prevent unauthorized transactions or data loss?
• Business continuity. What happens operationally if a key person or the primary office becomes unavailable?

Larger families and institutional investors sometimes retain specialist ODD consultants who do nothing else. The due diligence questionnaire submitted to a manager before investment is a standard starting document, but the answers require independent verification — not acceptance at face value.

Fees, Capacity, and Terms

Fee evaluation is part of manager selection, not an afterthought. How a manager is compensated shapes incentives in ways that matter for investors. A management fee covers operating costs; carried interest or performance fees align the manager with investor outcomes — in theory. The details matter: what is the preferred return hurdle? Is there a clawback if early gains are later reversed? Is there a fee offset that reduces the management fee when the manager earns monitoring or transaction fees from portfolio companies?

Capacity is a less-discussed but equally important question. Many strategies have a natural size limit beyond which performance is likely to erode — either because the opportunity set is too small to absorb more capital, or because large trades in a concentrated market become self-defeating. Asking a manager directly about their capacity estimate, and whether current assets under management are approaching it, is a legitimate and important question.

Red Flags and Common Mistakes

Certain patterns recur across manager evaluation failures. Families and their advisers sometimes find it useful to maintain an explicit list of concerns that would require resolution before proceeding:

• Performance records that cannot be independently verified or are presented inconsistently across documents
• Reluctance to provide third-party custodian or administrator contacts
• Inability to articulate clearly why a strategy has performed as it has
• Frequent changes in strategy or stated philosophy without clear explanation
• Unusually smooth return streams for a strategy that should exhibit some variability
• Pressure to commit capital quickly, before evaluation is complete
• Material discrepancies between the private placement memorandum and verbal representations
• Unexplained related-party transactions or conflicts of interest

A common mistake among families new to formal manager selection is conflating relationship comfort with analytical rigor. A manager who is well-known in the family's social network, easy to talk to, and responsive deserves no less scrutiny than an unfamiliar one. Rigorous process applies regardless of introduction source.

A qualified investment adviser, attorney, or due diligence professional should be involved in any manager evaluation of meaningful size. No checklist replaces professional judgment applied to a specific manager and a specific family's investment policy statement.
