Why the Price Mechanism Inside Your Agreement Deserves a Second Look
Most owners of closely held businesses have a buy-sell agreement in a drawer somewhere. It sets out what happens to an owner's interest when that owner dies, retires, becomes disabled, or simply wants out. It feels like a solved problem once it is signed. The part that often goes unexamined is the single most important clause in the whole document, which is how the business gets valued when the agreement is triggered.
A buy-sell can be properly signed and yet fail to do its job. What protects the owners is not the signed document but the valuation mechanism inside the agreement, and whether that mechanism still produces a fair, defensible price when the agreement is triggered. When the price falls short, as often happens, the agreement written to prevent a dispute becomes the source of the fight.
The reason this matters is timing. A buy-sell is written in a calm moment, when the owners agree and no money is changing hands. It is triggered years later under real pressure, often at a death or a falling out, when the departing owner is a seller, the remaining owner is a buyer, and every dollar of the price cuts against someone. A current, defensible value set by a clear method is what keeps that moment from turning into litigation. A stale number or a vague instruction is what invites the fight.
How Buy-Sell Valuation Mechanisms Usually Work
Most agreements set the price in one of three ways. The first is a fixed price, a dollar figure the owners agree to and are supposed to revisit each year. The second is a formula, such as a multiple of earnings or book value, meant to update the price automatically. The third is an independent appraisal, where a qualified valuation professional determines the value when the agreement is triggered.
Each can work, and each fails in a predictable way. Fixed prices are almost never updated, so they drift far from reality within a year or two. Formulas are chosen once and then quietly stop describing how the business actually earns, especially after the company grows or changes. Appraisal clauses are the most durable, but only when the agreement says clearly how the appraisal is to be done. The common thread is that the mechanism has to still produce a sound number on the day it is used, not the day it was written.
Key concept: a buy-sell agreement does not fix the value of your business. It fixes the method for finding that value later. If the method is stale or vague, the agreement can lock in the wrong number just when it counts most.
Where Valuation Comes In
A defensible valuation plays two roles in a buy-sell. Ahead of any trigger, it sets or resets the price on real evidence, so the owners agree to a number that reflects the business as it stands today. Then, when the agreement is triggered, it delivers a value that the departing owner, a surviving family, the remaining owner, and the IRS can all be asked to accept. How that value is reached matters as much as the number that results. Two choices drive that number. The first is the standard of value the agreement names, whether fair market value or an agreed value. The second is whether discounts for lack of control or lack of marketability apply to a partial interest. Either choice can move the price substantially, which is why these are not academic details. They decide whether the price holds up or gets challenged.
Defensibility matters most where the interest passes at death. A price set in a buy-sell is not automatically the value the IRS accepts for estate tax purposes. For the agreement to control that value, it generally has to meet specific requirements, and a price that looks like a bargain among family members draws particular scrutiny. An independent valuation, built on evidence rather than a round number chosen years earlier, is what gives the agreement its footing.
A Hypothetical Example
Assume Dave and Ron are equal owners of a closely held company called Ridgeline Manufacturing. Years ago, when they signed their buy-sell, they set a fixed price of $3.0 million for the whole company, which put each half at $1.5 million. They meant to revisit it every year. They never did. The business has done well since, and in very simple terms it would appraise today at roughly $10.0 million.
How the mechanism is supposed to work: when one owner leaves, the buy-sell tells the company or the remaining owner to buy the departing interest at the price the agreement sets. The whole point is that the number is already settled, so no one has to negotiate at the worst possible moment.
Now Ron dies unexpectedly. The agreement says his interest is bought for the fixed price, so his family is offered $1.5 million for a half of the business. In simple terms, that same half is worth closer to $5.0 million today before any valuation discounts are considered. Dave is following the agreement to the letter. Ron's family is convinced they are being shorted by millions. Nothing in the document is being violated, and yet everyone is heading toward a fight.
Why the stale number bites: the fixed price was set against a $3.0 million company and never moved. The business grew to about $10.0 million. In very simple terms, the agreement is now trying to transfer something worth roughly $5.0 million for $1.5 million, a gap of around $3.5 million on one interest. That is exactly the kind of gap that turns a buy-sell into a dispute.
Had the agreement instead called for an independent appraisal at the triggering event, or even required the fixed price to be refreshed periodically, the number would have tracked the business. Dave and Ron's family would be arguing about far less, or about nothing at all. Valuation does more than set a price here. It keeps the mechanism honest over time, so the agreement still does the job it was written to do.
What the Agreement Needs to Say About Value
An instruction to simply get an appraisal is not enough on its own. A well built valuation clause answers a handful of questions before they can become arguments. Which standard of value applies, and as of what date. Whether discounts for lack of control and lack of marketability apply to a less than controlling interest, since that choice alone can change the price meaningfully. Who selects the appraiser, what qualifications that appraiser must hold, and how a disagreement between two appraisers gets resolved. When those terms are spelled out, the mechanism produces one clear number. When they are left open, each side hires the valuation that helps its position, and the agreement has quietly recreated the very dispute it was meant to prevent.
There is an old proverb that the best time to plant a tree was thirty years ago, and the next best time is now. A buy-sell value works the same way. The best time to have put a realistic, defensible number behind the agreement was the day it was signed. The next best time is today. What matters is not any single method but that the number stays sound and current. For some businesses that means a fresh independent valuation done now and revisited periodically. For others it means keeping a formula honest, updating the multiple or the book value inputs so the calculation still reflects how the business actually earns. The common thread is straightforward. Set a realistic value while the owners are calm and aligned, and keep it up to date, rather than discovering at a triggering event that the number stopped making sense years ago.
Signs Your Buy-Sell Valuation May Be Worth a Second Look
- The agreement sets a fixed price that has not been updated in the last year or two.
- The price runs off a formula that was chosen long ago and may no longer reflect how the business earns.
- The agreement calls for an appraisal but does not define the standard of value, the valuation date, or whether discounts apply.
- Ownership, profitability, or the number of owners has changed materially since the agreement was signed.
At Eubank Capital, we work alongside business owners, their attorneys, and their CPAs to provide independent, defensible valuations for buy-sell planning in closely held businesses. We set or reset the agreed price on current evidence, review the valuation mechanism in an existing agreement for the gaps that cause disputes, and serve as the named independent appraiser when the agreement is triggered. The goal is a price that all sides, and the IRS, can be asked to accept.
