- TL;DR
A partner buyout valuation prices the exit of one owner by the remaining owner(s). A buy-sell agreement valuation determines the value used when a triggering event — death, disability, retirement, divorce, or termination — activates a pre-negotiated transfer of ownership. Both rely on the same defensible methodology: independent fair market value (or fair value, depending on the governing document), supported by AICPA SSVS No. 1 and USPAP. TC Advisors is led by a Certified Valuation Analyst (CVA) and Certified Exit Planning Advisor (CEPA), providing pre-event buy-sell valuations (drafting input, refresh, or compliance) and post-event partner buyout valuations (joint or single-party engagement) for Southern California business owners across San Diego, Orange, Los Angeles, and Riverside Counties.
- When You Need One
When You Need a Partner Buyout or Buy-Sell Valuation
Partner buyouts and buy-sell triggering events happen for predictable reasons: one owner is retiring, one is relocating, one wants to pursue a different venture, the partnership isn’t working, or a buy-sell agreement has been triggered by death, disability, divorce, or termination. Regardless of the reason, the question is the same: what is the business worth today, and what does the exiting owner’s interest equal?
Getting that number wrong — or getting it from a biased source — creates problems that surface months or years after the buyout closes. Tax authorities can challenge it. The exiting owner can claim they were underpaid. The remaining owner can claim they overpaid. Lenders financing the buyout require defensible documentation. Attorneys reviewing the transaction need to know the methodology will hold up.
A properly structured, credentialed valuation eliminates that risk before it starts — whether the engagement is post-trigger (a partner buyout in motion) or pre-trigger (drafting or refreshing the buy-sell agreement that will govern the next transition).

Partner buyout and buy-sell valuation methodology adapts to ownership structure. We work across the full range of closely held entity types:
- General partnerships and limited partnerships
Valuing partnership interests subject to partnership agreement provisions.
- Limited Liability Companies (LLCs)
Valuing membership interests under operating agreement terms, including manager-managed and member-managed structures.
- S-Corporations and C-Corporations
Valuing common and preferred shares, voting and non-voting interests.
- Professional Corporations and Professional LLCs
Medical practices, dental practices, law firms, accounting firms, engineering firms, and other licensed professional entities.
- Family-owned businesses
Multi-generational ownership with succession overlay.
- Joint ventures and member-managed operating entities
Non-standard structures requiring custom methodology.
The standard of value, discount methodology, and analytical framework depend on the structure. The sections below explain how.
- Engagement Structure
The Joint Engagement Approach
(Our Default)
When both owners are reasonably aligned on the need to transact — even if they disagree on price — we recommend starting with a joint engagement. Both owners hire TC Advisors together, share the cost, and receive one independent opinion of value.
One number, not two.
Competing valuations from each side’s hired valuator almost always produce a 30–50% spread. That spread becomes the negotiation, and the underlying business question gets lost.
Faster path to close.
A joint engagement typically resolves in 3–4 weeks. Competing-valuator processes routinely run 3–6 months once the spread starts getting litigated.
Lower total cost.
One engagement, shared. Competing valuations cost both owners separately, then often require a third “rebuttal” engagement to reconcile.
No advocacy bias.
A jointly engaged valuator has no client-side incentive. The methodology and conclusion are the same whether the exiting or remaining owner reads the report.
A defensible record.
If the IRS, a lender, or a future buyer ever questions the buyout price, a jointly engaged CVA report carries more weight than a single-party advocate report.
When Joint Engagement Isn't the Right Fit
Not every situation supports a joint approach. When the partnership has deteriorated, when one party refuses to share information, or when the matter is moving toward formal dispute, we can structure the engagement differently. TC Advisors offers single-party and mediation-stage valuation engagement structures. In any partner buyout or buy-sell inquiry, our first step is to understand the specific situation, the relationship between owners, and the goals of the engagement — then recommend the structure most likely to achieve those goals.
- Triggering Events
Common Triggering Events We Handle
Partner buyout valuations are usually prompted by one of four event categories. The category often determines the structure, standard of value, and timeline of the engagement.
Voluntary Exits
A partner is retiring, relocating, pursuing other ventures, or wants to liquidate their ownership interest. These situations are typically the most amicable, support a joint engagement, and produce the cleanest closings. Both parties' interests are usually aligned around business continuity and a fair price.
Buy-Sell Agreement Triggers
An event defined in the buy-sell agreement has occurred — death, disability, divorce, termination, or a defined withdrawal event — and the agreement requires a valuation to execute the buyout. The buy-sell provisions control methodology, standard of value, and discount treatment. The section below on buy-sell agreement valuation covers the pre-event drafting and refresh work that prevents the most common triggering-event disputes.
Partnership and Shareholder Disagreements
Strategic conflicts, compensation disputes, work-contribution inequities, or fundamental differences in business philosophy have made the partnership untenable. These engagements require careful structuring — sometimes joint, sometimes single-party, sometimes mediation-stage.
Buy-Sell Refresh and Periodic Updates
Even partnerships without a current dispute benefit from periodic valuation updates. Buy-sell agreements with outdated formula clauses ("two times prior year EBITDA") or stale stated values create future conflict. A current independent valuation, refreshed every 1–3 years, prevents that.
- Standard of Value
Standard of Value:
Why This Decision Drives Everything
The single most consequential decision in a partner buyout or buy-sell valuation isn’t the multiple — it’s the standard of value. Get this wrong and the entire conclusion is invalid.
Our methodology:
Read the governing documents first.
Before anything else, we review the operating agreement, partnership agreement, shareholder agreement, and any buy-sell agreement in place. If the documents explicitly state a standard of value — fair market value, fair value, investment value, or something custom — that controls. Most disputes about valuation methodology disappear once someone actually reads the document the owners signed.
When the documents are silent, we analyze.
Many operating and buy-sell agreements either don’t address standard of value or use ambiguous language. In that case, we evaluate:
- The purpose of the valuation (negotiated buyout, statutory dissent, tax filing, lender requirement).
- The state law that applies — California Corporations Code § 2000 mandates “fair value” in shareholder dissolution actions, which is different from fair market value.
- Relevant case law— California has substantial precedent on partner and shareholder buyout valuations, and federal tax court cases (Estate of Andrews, Mandelbaum v. Commissioner) influence discount methodology.
- AICPA SSVS No. 1 and USPAP standards, which govern how the conclusion must be documented regardless of standard.
Document the standard and the reasoning.
The report explicitly states which standard of value was applied, why, and the authority supporting it. That documentation is what makes the conclusion defensible.
- Buy-Sell Lifecycle
Buy-Sell Agreement Valuation:
Before, During, and After the Trigger
A buy-sell agreement is the contract that governs what happens when a triggering event occurs — death, disability, divorce, retirement, voluntary withdrawal, or a defined breach. Most buy-sell agreements specify how the business will be valued at that moment. Many specify it poorly.
Independent valuation work intersects with buy-sell agreements at three distinct points in the lifecycle, and the engagement structure is different at each one.
Our methodology:
Drafting Stage: Valuation Input Before the Agreement Is Signed
When attorneys draft or update a buy-sell agreement for closely held entities, the valuation provision is one of the most consequential clauses in the document — and one of the most common to be drafted poorly. The choice typically comes down to three approaches:
Drafting Stage: Valuation Input Before the Agreement Is Signed
- Formula clauses. “Two times prior year EBITDA.” “Book value plus goodwill.” Simple to administer, but formulas drift away from fair market value as the business evolves. A formula that worked in year one may produce a buyout price 40–60% below actual value by year seven. Formula clauses also create perverse incentives — an owner who controls discretionary expenses can manipulate the formula in the year before a planned exit.
- Fixed price with periodic update. The owners agree on a price annually or every two years, often with a fallback to appraisal if the price hasn’t been updated within a defined window. This is better than a static formula but only works if the update discipline is maintained. In practice, most “annual refresh” buy-sell agreements stop getting updated by year three.
- Appraised value with a defined process. The agreement requires an independent business valuation by a credentialed valuator (Certified Valuation Analyst or equivalent recognized designation) at the time of the triggering event, performed under a specified standard of value, with a defined methodology for resolving discount questions. This is the most defensible structure and the one most likely to hold up under IRS, lender, or litigation scrutiny.
TC Advisors performs the valuation work that supports buy-sell drafting decisions — independent appraisals that give attorneys and owners a defensible baseline number and a methodology framework to incorporate into the agreement language. We do not draft or execute buy-sell agreements; that work belongs to your attorney. Our deliverable is a single, flat-fee valuation report that the attorney and owners use to inform the agreement’s valuation provisions.
Refresh Stage: Periodic Valuation Updates Under an Existing Agreement
Even buy-sell agreements that specify an appraisal process benefit from periodic valuation updates between triggering events. A current valuation on file:
- Anchors negotiations if a trigger occurs unexpectedly.
- Surfaces value-driver issues that owners can address before they hurt a future buyout price.
- Satisfies lender, investor, and estate planning requirements that increasingly assume a recent independent valuation exists.
- Aligns owner expectations on value — partners with different mental models of “what the business is worth” generate friction long before any trigger event.
For most closely held entities in the $500K–$50M revenue range, a refresh every 1–3 years is appropriate. More frequent updates may be warranted for rapid-growth businesses, businesses approaching a planned exit window, or businesses subject to estate planning timelines.
Triggering Event Stage: Executing the Valuation the Agreement Requires
When a buy-sell agreement is triggered, the agreement controls. The valuator’s job is to read the document first, identify the standard of value, methodology, valuation date, and discount provisions the agreement specifies, and execute accordingly.
Common issues that surface at this stage:
- The buy-sell specifies a methodology that hasn’t been used in modern valuation practice for 20 years (e.g., “five times prior year earnings, no discounts”).
- The buy-sell is ambiguous on standard of value — saying “fair value” without defining whether that means statutory fair value (typically no discounts) or fair market value (discounts applicable).
- The buy-sell doesn’t address the valuation date — and the date materially affects the conclusion in a volatile market.
- The buy-sell references valuator credentials that no longer exist or names a specific firm that’s no longer in business.
When the agreement is ambiguous or unworkable as written, the parties and their attorneys have to negotiate around the gaps before the valuation can proceed. We surface those issues during the engagement letter stage so they don’t derail the timeline mid-engagement.
- Recent Supreme Court Ruling
The Connelly v. United States Issue (2024)
In Connelly v. United States (June 6, 2024), a unanimous U.S. Supreme Court held that life insurance proceeds received by a corporation to fund a buy-sell redemption increase the value of the corporation for estate tax purposes — and that the corporation’s obligation to redeem the deceased shareholder’s stock does not offset the proceeds as a liability. The ruling overturned the prior reliance on Estate of Blount v. Commissioner (11th Cir. 2005) and materially changed how many closely held buy-sell agreements should be structured.

A current valuation that explicitly addresses life insurance proceeds and the Connelly implications is increasingly being requested by estate planning attorneys and CPAs working with closely held entity owners. We perform the valuation analysis; the attorney handles the agreement restructuring.
- Discounts
Discounts: DLOM, DLOC, and Why Generic Approaches Fail
Discounts for lack of marketability (DLOM) and lack of control (DLOC) are where partner buyout and buy-sell valuations get challenged most often. Applying a generic “industry standard” discount is the fastest way to get a report invalidated. And under a buy-sell agreement, discount treatment may be controlled by the agreement itself — the methodology has to align with what the document specifies.
Our approach uses the full body of empirical evidence:
- Restricted stock studies Stout Restricted Stock Study, FMV Opinions studies.
- Pre-IPO studies Valuation Advisors, Willamette.
- Mandelbaum factors For DLOM analysis on a facts-and-circumstances basis.
- Quantitative Marketability Discount Model (QMDM) When supported by the engagement.
- Control premium studies Mergerstat / FactSet for DLOC.
Critically, in some standards-of-value applications — particularly fair value under California Corporations Code § 2000 — DLOM and DLOC are typically not applied at all. Knowing when not to apply discounts is as important as knowing how to calculate them.
The discount conclusion is documented with the supporting studies, the reasoning, and the facts of the specific company being valued. That documentation is what holds up under scrutiny.

- Lead Engagement Partner
Brandon Bay, CVA, CEPA
Brandon leads every partner buyout and buy-sell valuation engagement personally. Direct engagement with a credentialed CVA — not associate-level delegation — is a deliberate firm policy.
- Advisory Team Coordination
Working Alongside Your Advisory Team
Most partner buyout and buy-sell transactions involve a team: a corporate or transactional attorney, an estate planning attorney, a CPA, often a financial advisor or wealth manager, sometimes a banker financing the buyout. The valuation works best when it works with that team, not in isolation.
We coordinate directly with your legal counsel on standard-of-value questions and buy-sell drafting language, with your CPA on tax implications of the structure, and with the lender on documentation requirements. The valuation report is built to support the legal and financial decisions the rest of your team is making — not to live in a vacuum.
If you don’t have a full advisory team in place, we can introduce you to attorneys and CPAs in San Diego, Orange, Los Angeles, or Riverside Counties who handle partner buyouts and buy-sell agreements.

Healthcare Services · Two-Partner · Joint Engagement
Two-partner healthcare services company, Southern California, approximately $4–6M revenue, 50/50 ownership
One partner was retiring after more than a decade of operation. The buy-sell agreement existed but didn’t specify a standard of value, didn’t address discounts, and didn’t define a valuation date methodology.
Before issuing the engagement letter, we walked both partners through the gaps in the buy-sell agreement and presented the options for standard of value, discount methodology, and valuation date. Both partners agreed in writing to the structure. We then executed a joint engagement and delivered a single valuation report.
The partners used the report as the basis for negotiation and closed the buyout shortly after delivery. Both retained the right to negotiate around the conclusion — what they couldn’t do anymore was argue about the underlying valuation methodology.
- FAQ
Frequently Asked Questions.
Common questions about timeline, joint engagement structure, standard of value, discounts, and the Connelly ruling.
How long does a partner buyout or buy-sell valuation take?
Three to four weeks from execution of the engagement letter, assuming reasonable information turnaround. Complex engagements involving site visits, multiple entities, or unusual capital structures can take longer. We provide a specific timeline in the engagement letter.
Can both partners hire one valuator together?
Yes — this is the joint engagement structure we recommend whenever the partnership relationship supports it. Both partners share the engagement, share the cost, and receive one independent opinion of value used as the basis for negotiation.
What's the difference between valuing a 50/50 partnership and a minority interest buyout?
A 50/50 buyout typically values the enterprise and divides accordingly, with discounts applied based on the standard of value and the governing documents. A minority interest buyout (anything under 50%) raises additional questions about lack of control and lack of marketability — discounts that can materially affect the conclusion. We address both structures, and the discount methodology is documented either way.
What if our buy-sell agreement specifies a different valuator or methodology?
The buy-sell agreement controls. If it specifies a valuator, a methodology, or a standard of value, those provisions are followed unless both owners agree in writing to modify them. We review the buy-sell agreement before issuing an engagement letter to surface any provisions that affect scope.
Should our buy-sell agreement use a formula, a fixed price, or an appraisal?
Appraised value with a defined process is the most defensible structure for closely held entities in the $500K–$50M revenue range. Formula clauses drift from fair market value as the business evolves and create incentive problems. Fixed-price agreements work only if the price is genuinely updated on schedule, which rarely happens in practice. An appraisal clause that specifies the credentials of the valuator, the standard of value, and a defined methodology for handling discounts produces conclusions that hold up under IRS, lender, and litigation scrutiny.
How often should a buy-sell valuation be refreshed?
Every 1–3 years for most closely held entities in our typical client range. More frequent updates are appropriate for rapid-growth businesses, businesses approaching a planned exit window, businesses with significant estate planning exposure, or businesses where the partners have materially different views of current value. A current valuation on file prevents disputes when a triggering event occurs and supports estate planning, lender, and investor requirements.
What changed with Connelly v. United States (2024)?
In Connelly, the U.S. Supreme Court held unanimously that life insurance proceeds received by a corporation to fund a buy-sell redemption increase the value of the corporation for estate tax purposes — and that the corporation’s obligation to redeem the deceased shareholder’s stock does not offset the proceeds. For closely held entities with redemption-funded buy-sell agreements, this created a new estate tax exposure that didn’t previously exist under Estate of Blount. Owners and attorneys are increasingly restructuring buy-sell agreements toward cross-purchase or special-purpose LLC structures to avoid the Connelly result. A current valuation that explicitly addresses life insurance and Connelly implications is part of that review.
Our buy-sell agreement specifies a methodology that seems outdated. What do we do?
The buy-sell agreement controls unless both owners agree in writing to modify it. If the methodology is unworkable, ambiguous, or hasn’t been used in modern valuation practice for decades, the most efficient path is to amend the agreement with current language before the valuation engagement begins — typically through coordination with the parties’ attorneys. We surface these issues during the buy-sell review at the engagement letter stage so they’re resolved before the valuation proceeds, not mid-engagement.
Do you apply standard discounts for lack of marketability and control?
Discounts are determined by the standard of value, the specific facts of the company, and applicable law — not by a default. In some applications (such as California Corp. Code § 2000 fair value cases), discounts are typically not applied at all. We document the discount conclusion with supporting studies and reasoning.
What credentials should a partner buyout or buy-sell valuator have?
At minimum, a recognized business valuation credential — the Certified Valuation Analyst (CVA) from NACVA or an equivalent recognized designation. For buy-sell work tied to exit planning, the Certified Exit Planning Advisor (CEPA) credential adds relevant context. The report should comply with the AICPA Statement on Standards for Valuation Services No. 1 (SSVS No. 1) and USPAP. Reports from non-credentialed preparers are routinely challenged.
What happens if one partner disagrees with the valuation?
In a joint engagement, both partners have access to the same report and the same documented methodology. Disagreement about the conclusion typically resolves through negotiation between the partners and their attorneys. The valuation provides the defensible starting point — the partners decide what to do with it.
Do you work with our existing attorney and CPA?
Yes — and we strongly recommend it. Partner buyout and buy-sell transactions involve legal structure, tax implications, and often financing. The valuation is one piece of a coordinated transaction. We coordinate directly with your existing advisory team.
Where do you serve?
San Diego, Orange, Los Angeles, and Riverside Counties primarily, with select engagements throughout California.
