Making Buy-Sell Agreements Work: Valuation Mechanisms and Drafting Pitfalls

Executive SummaryBuy-sell agreements are a cornerstone of planning for closely held businesses and family enterprises. Advisors spend significant time addressing ownership transitions, funding mechanisms, and tax considerations. Yet despite their importance, valuation provisions in buy-sell agreements are often treated as secondary drafting issues. Too often, they are boilerplate clauses that receive far less scrutiny than they deserve. When buy-sell agreements fail, valuation provisions are often the root cause.This article is the first in a two-part series examining how buy-sell agreements function in practice and why so many fall short of their intended purpose. Part I focuses on the valuation mechanisms commonly used in buy-sell agreements – fixed price, formula pricing, and appraisal-based processes – and explains the structural weaknesses that often undermine them. Drawing on our extensive valuation experience, we offer a practical framework for designing valuation provisions that are more likely to produce fair, predictable, and workable outcomes when a triggering event occurs.Part II will address what is required for buy-sell agreement pricing to be used to fix the value for gift and estate tax matters, including the requirements of Internal Revenue Code §2703 and guidance from key court cases such as Estate of Huffman and Connelly. Together, these articles are intended to help estate planners move beyond theoretical drafting and toward buy-sell agreements that withstand both real-world and IRS scrutiny.Common Buy-Sell Valuation MechanismsMost buy-sell agreements fall into one of four categories based on how price is determined:Fixed priceFormula pricingMultiple appraiser processSingle appraiser processEach approach has perceived advantages, but each also carries structural weaknesses that estate planners should carefully evaluate.Fixed-Price AgreementsFixed-price buy-sell agreements establish a specific dollar value for the business or ownership interests based on the owners’ agreement at a point in time. Their appeal lies in simplicity. The price is clear, easily understood, and inexpensive to administer. In theory, fixed-price agreements encourage owners to revisit and reaffirm value periodically.In practice, however, fixed prices are rarely updated with sufficient frequency. As the business evolves, the fixed price may become materially understated, overstated, or – by coincidence – approximately correct. The fundamental problem is not the use of a fixed price, but the absence of a reliable and consistently followed process for updating it. When the price becomes stale, incentives become misaligned. An unrealistically low price benefits the remaining owners, while an inflated price benefits the exiting owner. These distortions undermine fairness and often surface only after a triggering event, when renegotiation is least likely to succeed.Formula Price AgreementsFormula pricing agreements determine value by applying a predefined calculation, often based on financial statement metrics such as EBITDA multiples, book value, or shareholders’ equity. These agreements are frequently viewed as more objective than fixed prices and are attractive because they appear to adjust automatically as financial results change.The perceived precision of formulas is often illusory. Over time, changes in the business model, capital structure, accounting practices, or industry conditions can render a once-reasonable formula obsolete. Even when formulas are recalculated mechanically, they may fail to reflect economic reality (book value as a formula is a prime example of this). More importantly, most formula agreements lack guidance on when or how the formula itself should be revisited. Without periodic reassessment, formula pricing can embed significant inequities into the agreement while giving shareholders a false sense of certainty of fairness. Formula price agreements also fail to account for any non-operating assets that may have accumulated on the balance sheet. Valuation Process AgreementsValuation process agreements defer the determination of price until a triggering event occurs and rely on professional appraisers to establish value at that time. These agreements generally fall into two categories: multiple appraiser processes and single appraiser processes.Multiple Appraiser ProcessUnder a multiple appraiser process, each side appoints its own appraiser to value the business following a triggering event. If the resulting valuations differ beyond a specified threshold, the agreement typically calls for the appointment of a third appraiser to resolve the difference or render a binding conclusion.While this approach is intended to ensure fairness through balanced input, it often introduces uncertainty, delay, and cost. The final price, timing, and expense of the process are unknown at the outset. In addition, even well-intentioned appraisers may be perceived as advocates for the parties who selected them, complicating negotiations and eroding confidence in the outcome. For family-owned businesses in particular, the multiple appraiser process can unintentionally escalate conflict at a sensitive moment.Single Appraiser ProcessUnder a single appraiser process, one valuation firm is designated, either in advance or at the time of a triggering event, to perform a valuation. This approach is generally more efficient and cost-effective and avoids dueling opinions. When valuations are performed periodically, it can also make outcomes more predictable well before a triggering event occurs. Its effectiveness, however, depends entirely on careful advance planning and drafting.A More Effective Framework: “Single Appraiser: Select Now, Value Now and Annually (or Periodically) Thereafter”Given the shortcomings of traditional valuation mechanisms, is it possible to design a buy-sell valuation process that reliably produces reasonable outcomes? We believe it is.Based on extensive buy-sell agreement related valuation experience, we recommend a framework built on three principles: selecting the appraiser in advance, exercising the valuation process before a triggering event, and careful drafting of the valuation language in the agreement. 1. Retain an Appraiser NowEstate planners and other attorneys who draft buy-sell agreements should encourage clients to retain a qualified business appraiser at the outset, rather than waiting for a triggering event. Conducting an initial valuation transforms abstract agreement language into a concrete report that shareholders can review, understand, and question. This process reveals ambiguities in the agreement, clarifies expectations, and allows revisions to be made when no party knows whether they will ultimately be a buyer or a seller.This “Single Appraiser: Select Now, Value Now and Annually (or Periodically) Thereafter” approach offers several advantages:The valuation process is known and observed in advanceThe appraiser’s independence is established before any economic conflict arisesValuation methodologies and assumptions are understood by all partiesThe initial valuation becomes the operative price until updated or conditions changeAmbiguities in valuation language are identified and corrected earlyFuture valuations are more efficient, consistent, and less contentious2. Update the Valuation Annually or PeriodicallyStatic valuation mechanisms do not work in a dynamic business environment. Annual or periodic valuation updates help align expectations and reduce the likelihood of surprise or dissatisfaction when a triggering event occurs. In practice, disputes are more often driven by unmet expectations than by the absolute level of value. Regular valuations promote transparency and reduce friction.3. Draft Precise Valuation LanguageEven the best valuation process can fail if the agreement lacks clarity. Attorneys drafting buy-sell agreements should ensure that the agreements address, at a minimum:Standard of value (e.g., fair market value vs. fair value)Level of value (enterprise vs. interest level; treatment of discounts)Valuation date (“as of” date)Funding mechanismAppraiser qualifications (making certain to use business appraiser qualifications. For example, a “certified appraiser” refers to a real estate appraiser, rather than a business valuation expert.) Applicable appraisal standardsAmbiguity on any of these points materially increases the risk of divergent interpretations and unsuccessful outcomes.ConclusionBuy-sell agreements fail not because valuation is inherently subjective, but because valuation provisions are often left ambiguous, untested, or static. Estate planners and other attorneys who draft buy-sell agreements play a critical role in preventing these failures. By selecting appraisers in advance, exercising valuation processes periodically, and carefully drafting valuation language, advisors can dramatically improve the likelihood that a buy-sell agreement will function as intended.When valuation mechanisms are designed with the same rigor as tax and estate plans, buy-sell agreements can become durable planning tools capable of delivering predictability, fairness, and continuity when they are needed most. And the buy-sell agreement pricing may even be able to be used to fix the value for gift and estate tax filings. We will discuss this in Part II.For advisors who want to delve deeper into valuation concepts, planning strategies, and practical applications in estate and business succession planning, we recommend Buy-Sell Agreements: Valuation Handbook for Attorneys by Z. Christopher Mercer, FASA, CFA, ABAR (American Bar Association), written by our firm’s founder and Chairman. This book offers a thorough treatment of valuation issues and provides example language for consideration by attorneys when drafting buy-sell agreements that contain language important to the valuation process.

Documenting Fair Market Value: Lessons from Estate of Rowland v. Commissioner

A Guide for Estate PlannersExecutive SummaryBusiness valuations that are well-documented with support for the methodology used and how the concluded value was arrived at are at the core of effective estate tax planning. The recent decision in Estate of Rowland v. Commissioner (T.C. Memo. 2025-76) reinforces that truth by showing how incomplete valuation documentation within Form 706 can jeopardize an otherwise straightforward portability election.While Rowland involved a filing delay, the Court’s opinion makes clear that a deficient or poorly documented valuation can be just as damaging as a missed deadline. For estates holding closely held business interests, which are often significant and complex assets, the importance of thoroughly documenting the process of reaching fair market value cannot be overstated.Background: The Portability Election and Form 706Under Internal Revenue Code § 2010(c)(5)(A), a surviving spouse may use any portion of the deceased spouse’s unused estate tax exclusion (the deceased spousal unused exclusion, or “DSUE”) if the first spouse’s executor properly elects portability.That election must be made through a timely filed and complete Form 706. Even when an estate owes no estate tax, the return must contain detailed and supportable valuations of every asset, including business interests. Omitting or estimating values exposes the election to IRS challenge and potential invalidation.Facts of the CaseFay Rowland died in 2016, leaving an estate approximately $3.7 million below the filing threshold. Her executor obtained a six-month extension but filed Form 706 nearly six months after the extended deadline.The return also lacked key valuation detail: 1) schedules reflected only estimated totals, not fair market values for individual assets; and 2) the executor claimed the “relaxed reporting” exception for assets passing to a surviving spouse, yet a portion of the estate passed to grandchildren’s trusts, making the exception inapplicable.When the surviving spouse’s estate (Billy Rowland) later claimed Fay’s DSUE, the IRS denied the election, arguing the filing was neither timely nor properly prepared. The Tax Court agreed, which lead to Billy’s Estate paying approximately $1.5 million in additional taxes.The Court’s ReasoningTimeliness Was Not EnoughThe Court held the return untimely, but even if it had met the filing window, it failed the requirement of being “complete and properly prepared.” Completeness, the Court emphasized, includes providing valuation information sufficient for the IRS to verify reported amounts and compute the DSUE accurately.Valuation Documentation Is Integral to CompletenessTreas. Reg. § 20.2010-2(a)(7) requires a Form 706 filed solely to elect portability to include the same detail as a taxable return, except for assets passing entirely to a spouse or charity. The Rowland estate’s generalized estimates prevented the IRS from evaluating the DSUE computation.The Court rejected arguments of substantial compliance and equitable relief, holding that valuation documentation is not simply a procedural technicality, but rather a statutory prerequisite.Why Business Valuations MatterFor many families, closely held business interests comprise a large share of estate value. These assets require specialized valuation under Revenue Ruling 59-60. A well-supported valuation not only establishes compliance but also enhances the credibility of the entire filing.A defensible business valuation requires:Identifying the rights and benefits of the interest being valued (control, transfer restrictions, etc.).Using relevant market evidence, including public comparables and transaction data.Applying sound financial analysis that addresses expected cash flows, risk, and growth prospects.Reporting clearly and effectively to the IRS and other readers.Documentation: The Bridge Between Valuation and ComplianceThe Rowland decision underscores that a valuation unsupported by documentation is no valuation at all. A properly prepared Form 706 should therefore include:Narrative descriptions of each business interest, outlining ownership, structure, and rights.Detailed valuation schedules explaining how conclusions were reached.Supporting exhibits, such as financial statements and methodology summaries.Explicit reference to appraisal standards that demonstrate compliance with USPAP and Treasury requirements.Without these elements, a return fails the “complete and properly prepared” standard which is exactly what happened in Rowland.Practical Guidance for Estate PlannersEngage Qualified Appraisers Early. Business interests should be appraised by professionals experienced in federal transfer tax matters and IRS examinations.Coordinate Across Disciplines. Attorneys, accountants, and appraisers should align on ownership structures and entity specifics to ensure consistent reporting.Avoid Estimates or Prior-Year Values. Fair market value is determined as of the date of death; using approximations risks inconsistency with IRS standards.Explain Discounts and Assumptions. Clearly document the rationale for any discount for lack of control or marketability.Maintain Comprehensive Records. Preserve valuation reports, source data, and correspondence to support the filing if later reviewed or aud.ConclusionThe Estate of Rowland v. Commissioner decision delivers a clear message: Form 706 filings must contain credible, well-documented fair market value determinations for all assets, particularly business interests, or risk invalidation. Portability hinges not only on timeliness but on the completeness and substantiation of reported values. The strength of the filing lies in the quality of its appraisals and the documentation supporting them.At Mercer Capital, we integrate these principles into every estate and gift tax engagement, ensuring our valuation opinions are technically sound, clearly presented, and defensible which positions clients for successful outcomes under IRS scrutiny.Valuations are a critical element of successful tax planning strategies and objective third-party valuation opinions are vital.

The Value of Carried Interest in Estate Planning: A Guide for Newly Formed Funds

As we stated in the March 2025 issue of this newsletter, we believe that prudent federal estate and gift tax planning involves a lifetime horizon with adherence to best practices that yield optimal outcomes. When economic and market conditions present an opportunity for estate planning, assets with low current values and potential for significant appreciation should be considered for efficient estate planning. One type of asset that fits this category is carried interest. This article explores the strategic incorporation of carried interests in estate planning, particularly for newly formed private equity funds. It discusses the benefits and complexities of leveraging such interests under current economic conditions and tax regulations to optimize estate outcomes. We will discuss specific valuation approaches and methods in the valuation of carried interests in a future article.Carried Interest ExplainedWhat is carried interest? It is the profits interest that a private equity, venture capital, or hedge fund principal receives if the fund exceeds certain performance benchmarks. Carried interest can also be referred to as performance allocation, incentive allocation, or promote interest in the case of real estate funds. Separately, fund principals also receive economics from management fees and direct investments in the fund. Fund Structures and Carried Interest AllocationA basic private equity fund structure is shown in Figure 1. Typically, the fund principals form a general partner entity and a management company entity. The principals then raise capital from limited partners and make investments over the term of the fund. The management company receives management fees, often around 2% per year, for investment management services provided. The general partner entity typically invests alongside the limited partners and receives its pro-rata share of returns along with the limited partners. If the fund exceeds certain benchmarks, the general partner also receives carried interest, often around 20% of fund returns beyond the benchmark. It is important to note that private equity fund structures come in many forms, from basic to complex. Even though this article is focused primarily on private equity funds, similar concepts apply to certain hedge funds and venture capital funds.Navigating Uncertainty and Valuation ChallengesUncertainty exists regarding the fund’s performance, more so earlier in the fund’s life. When the fund entities are formed, and before capital is raised, there is also uncertainty regarding how much capital will be raised. These uncertainties result in low values for the fund entities at inception. The fund entity values will appreciate significantly if the fund is able to successfully raise capital and achieve strong investment returns.Why would a newly formed fund entity have any value before capital is raised? The IRS’ Revenue Procedure 93-27 provides that if a person receives a profits interest for the provision of services to or for the benefit of a partnership in a partner capacity or in anticipation of being a partner, the IRS will not treat the receipt of such an interest as a taxable event for the partner or the partnership. It has been argued that 93-27 means that a profits interest has no value at issuance. However, the IRS has made it clear that 93-27 is not applicable to valuing carried interest.Challenges in Valuing Interests in Fund EntitiesA qualified appraisal prepared by a qualified appraiser with experience valuing carried interest is paramount when making estate planning transfers with newly formed fund entity interests given the complexity involved. In addition to fund structure, other items that require appraiser familiarity with carried interest include the following:Fundraising: What is the fund’s target size? What is the minimum required investment? Will the fund offer special terms for early investors or for a large “anchor” investor?Fund investment strategy: What types of investments will the fund make in terms of asset classes, industries, size of interests, number of investments, etc.? How will the investments shape expected returns for the fund? What is the expected holding period for the investments? Will capital from the sales of investments be reinvested? Will the fund use leverage?Fund terms: How is the management fee calculated and how often will it be assessed? Who will pay for fund expenses? Is there a general partner catch-up after the hurdle is reached? Are distributions made on a deal-by-deal basis, or on a cumulative basis? Can the general partner waive management fees associated with their direct investments in the fund?ConclusionIn conclusion, carried interests in newly formed fund entities present a valuable estate planning opportunity, particularly during times of economic uncertainty and where there is potential for fund appreciation.It is essential to work with qualified appraisers familiar with the complexities of fund structures and tax regulations to ensure optimal outcomes. Engaging with experienced advisors can significantly enhance the outcomes of your estate planning efforts.The professionals at Mercer Capital have experience in the valuation of carried interests.
