Documenting deal structure decisions for board or IC review

The sale and purchase agreement records what the parties agreed: the consideration, the conditions, the covenants. It does not record why the deal team chose cash over equity, or why it accepted an earn-out instead of holding out for a higher fixed price. That reasoning lives in email threads, model versions and meeting memories, and it decays fast. A board or investment committee that approved the transaction, and an auditor or successor deal team that examines it two years later, both need a separate artifact: a decision record that sets out the structure chosen, the alternatives rejected and the evidence behind each judgement.

This is not an exotic practice. Formal decision documentation is already the norm among professional investors. In a survey run by Addepar with the Stanford Initiative on Long-Term Investing, 97% of the professional investors surveyed use a formal investment memo template and process, and 78% of their firms require memo approval before making any investment^[1]. The memo is what allows a committee to approve, condition or decline a deal on the reasoning rather than on the pitch. A deal structure decision record applies the same discipline to the specific question of consideration structure, so the choice of cash, equity or earn-out can be interrogated on its evidence at IC and re-examined after closing.

One scope note before going further. This article covers the decision record as a governance artifact for board and IC review. It does not cover the legal implications of deal structure, tax optimization, SPA drafting or negotiation, jurisdiction-specific contract law, earn-out enforceability, or any form of legal or financial advice. Those questions belong to qualified counsel and tax advisers. What follows is about documenting the commercial reasoning so that directors can review it and auditors can later reconstruct it.

• What the SPA gives you: the agreed terms, not the reasoning behind them.
• What the decision record adds: the structure chosen, the alternatives considered, the evidence for each, and the assumptions relied on.
• Who uses it later: the board and IC at approval, auditors and later diligence teams after closing, and the deal team itself when assumptions need tracking.

The record should start by defining the structure choices in plain terms, because each carries a different signal that the board is implicitly endorsing when it approves the deal.

The earn-out numbers deserve particular care in the record, because they are the ones a director is most likely to challenge. Outside life sciences, earn-out usage rose from 15% of private deals in 2019 to a high of 30-37% in 2023 before settling back to approximately 22% in 2024, and private pharmaceutical transactions have used earn-outs in over 80% of deals in recent years. A record that simply notes "earn-out included" tells the board nothing; a record that states the contingent share of consideration, the metric chosen, the performance period and why that shape fits this deal gives the board something it can actually approve.

Whichever structure is recommended, the record should state in one or two sentences what the choice signals and what it commits the firm to. Cash at close commits the buyer's funding and expresses confidence in its own valuation. Rollover commits the firm to a governance relationship with former owners. An earn-out commits both sides to a monitoring regime for the performance period. Those commitments, not just the headline price, are what the board is approving.

A decision record earns its keep by attaching evidence to every option considered, not only to the one recommended. Three categories of evidence matter most.

• The valuation basis behind each structure: the analysis that produced the headline value, and how the structure modifies it, for example how an earn-out splits fixed and contingent value.
• Sensitivity cases for each option: upside, base and downside, so the committee can see how the choice behaves when the forecast is wrong. Scenario ranges of this kind are a standard memo component in professional investment processes^[1].
• The assumptions that drive the choice: growth rates, margin trajectory, integration costs, funding terms, each with its source, so they can be tracked after closing rather than rediscovered.

For earn-outs specifically, the record should capture the risk data alongside the upside case, because the post-closing evidence is sobering. A Grant Thornton survey of 150 active deal participants found that of the total deals with post-close earn-out adjustments, 26% were disputed^[2]. SRS Acquiom market data shows that earnouts achieve about 21 cents on the dollar of their stated maximum and are contested at least 28% of the time; of the 59% of deals that paid anything on the earnout, 17% required renegotiation to avoid litigation^[3].

These figures belong in the record as decision evidence, framed carefully: they describe observed market outcomes, not the enforceability of any particular provision, and they are not legal advice. Their function is to force the deal team to state why this earn-out, on this metric, over this period, is expected to behave differently from the market average, or to accept explicitly that it is not. A committee that sees the dispute data can weigh the contingent element with open eyes; one that sees only the upside case cannot.

The same discipline applies to the rejected options. If equity was rejected because the seller wanted certainty, or cash was rejected because funding terms made it uneconomic, that reasoning and its evidence should sit in the record next to the earn-out analysis. The evidence bar for AI-assisted deal analysis is a useful reference point here: every material claim in the paper should be traceable to a document a director can pull up, a standard set out in guidance on the IC evidence bar.

The anatomy of a defensible record is straightforward, and it mirrors what professional investors already standardise. The Addepar and Stanford research found that memos converge on a common set of sections, with the most important being deal description, risk factors, team bios and deal terms, and that 86% of firms use standard templates^[1]. A deal structure decision record should contain, at minimum:

1. The recommendation and rationale in the deal team's own words: which structure is proposed, in what proportions, and the two or three reasons that actually drove the choice, not a restatement of the model output.
2. The alternatives considered and why each was rejected: full cash, full equity, blended structures, a different earn-out metric or period, each with the evidence that killed it.
3. The evidence for each choice: valuation basis, sensitivity cases and key assumptions, as set out above, each traceable to a source document.
4. Risks and mitigants: what could make the chosen structure misfire, from funding stress to earn-out metric gaming, and what the team proposes to do about it.
5. Dissenting views: any committee member or director who disagreed, and the substance of the disagreement, recorded fairly.
6. The draft resolution: the exact wording the board or IC is being asked to approve, included in the paper itself.

The dissent point is not optional decoration. The joint statement on board minutes from the Australian Institute of Company Directors and the Governance Institute of Australia advises that minutes should record the reason the majority of directors were in favour of the decision notwithstanding dissenting views, and that votes against or abstentions should be included^[4]. A record that shows a real debate, and shows why the majority prevailed, is stronger governance evidence than one that reads as unanimous because the dissent was left out.

Structuring the memo itself is a craft with established conventions, and teams that want a deeper template can draw on guidance on structuring an investment committee memo and diligence deck, which covers IC memo structure in detail. The principle is the same regardless of format: the record should let a director move from conclusion to evidence to source in three steps, without leaving the document.

The test of a good record is not whether it defends the conclusion but whether it answers questions. Three presentation practices make the difference.

• Link every claim to its source. Each figure and assertion in the paper should point to the document behind it, and the key documents the directors relied on should be tabled at the meeting and referred to in the minutes, as Freshfields guidance on board records recommends^[5]. A claim that cannot be traced is an assertion, not evidence.
• Include the draft resolution in the board paper itself, so directors know precisely what they are approving rather than reconstructing it from discussion. Board papers can be incorporated by reference into the minutes, which is exactly why the paper needs to carry the reasoning^[4].
• Pre-load the questions directors actually ask. Why an earn-out rather than a lower fixed price? Why this metric and not EBITDA, or revenue? What happens to the record if the performance period is extended? Why is the contingent share defensible given observed dispute rates? Each anticipated question should have its answer and its evidence already in the paper.

The interrogation-friendly paper also keeps the decision frame tight. Boards work best when materials are built around decisions rather than description, a point developed in guidance on turning board reporting into decision-focused board packs. For a structure decision, that means the paper leads with the recommendation and the resolution, and arranges the evidence underneath it, rather than burying both at the end of a market update.

Finally, resist the temptation to polish the record into advocacy. Directors are experienced at detecting a paper that argues rather than documents, and an easy review is a governance failure, not a compliment. A record that surfaces its own weak points, the downside case, the dissent, the dispute data, invites the scrutiny that makes the approval durable.

The record's value does not end when the resolution passes. Its downstream uses are arguably where it earns most.

• A time-stamped artifact of assumptions. The Addepar and Stanford research treats memos as records of the thinking and assumptions an investor relied on, and argues those assumptions should be tracked over time as they change^[1]. For a structure decision, that means the growth, margin and integration assumptions behind an earn-out can be compared against actuals each quarter, rather than reconstructed from memory.
• Reappearance in later diligence and disclosure. Freshfields notes that board minutes may need to be disclosed in transaction due diligence, in response to regulatory or freedom of information requests, or in legal proceedings, and that any such external review may take place long after the meeting^[5]. The structure record written for IC is, in practice, written for those future readers too.
• A learning loop. Comparing the documented rationale against post-deal performance, including on deals the firm passed on, is what turns individual decisions into institutional judgement. The research identifies this storing, learning and improving cycle as a standard stage of memo processes^[1].

The earn-out makes this loop concrete. If the record documented a 24-month performance period with a revenue metric and specific assumptions behind the targets, the post-deal review can ask a precise question: which assumption failed, and would the team choose the same structure again knowing that? Earn-out achievement data showing payouts at about 21 cents on the dollar makes that review genuinely informative rather than anecdotal^[3].

Accuracy and traceability are the conditions on which the record's credibility rests, and both need active management after the meeting as well as before it.

• Correct errors promptly and transparently. If a wrong number is discovered in a board paper or record after the meeting, the response should follow a structured protocol rather than a quiet fix; guidance on correcting a wrong number in a board paper covers error triage and written notification to the chair and company secretary.
• Respect the boundary between clerical and substantive change. Governance guidance is clear that minutes, once signed by the chair, are the legal record of the meeting; directors should request additions, clarifications or corrections while the minutes are being finalised, and substantive changes to what was decided require a new resolution rather than an edit^[4]. Freshfields adds the caution from case law that courts will reject language added to minutes at a later date where there is evidence it does not reflect the facts^[5].
• Make every number traceable to its source. The record survives re-examination only if each figure in it can be followed back to the document, model version or data extract behind it, at the time of the decision and years later.

Traceability is also the discipline that keeps AI-assisted drafting honest. Fluent output makes it easy for a record to read better than its evidence, which is why a fact-checking pass that distinguishes attributable claims from source-flavoured prose should precede any IC submission fact-checking AI-drafted decks.

This is the problem Decisity was built for: as an AI-native strategy consulting platform, it turns briefs and documents into board-ready deliverables in which every conclusion is traceable to its source, so a structure decision record can carry its evidence with it through IC review, post-deal audit and everything in between. A deal structure choice documented that way stops being paperwork and becomes what it should be: a governance artifact that still holds up the day someone finally asks why.
