When a privately held business becomes part of an estate, divorce proceeding or commercial dispute, determining its value is rarely as simple as looking at revenue or applying an industry multiple. The valuation may affect taxes, ownership interests, settlement negotiations or damages, making the methodology behind the conclusion just as important as the final number.

A corporate valuation in these situations must begin with the purpose of the assignment. An estate tax matter may require fair market value, while a divorce case may involve a jurisdiction-specific fair value standard. Litigation may require a valuation of an ownership interest, damages analysis or another measure defined by the legal issues in the case.

The valuation date also matters. A business can change substantially over a few months because of revenue growth, customer concentration, debt, management changes, economic conditions or a major transaction. A defensible corporate valuation therefore needs to establish what is being valued, as of what date and under which standard of value.

For attorneys, the objective is not simply to obtain a business valuation report. The objective is to develop an analysis that is consistent with the applicable legal framework, supported by reliable financial evidence and capable of being explained under scrutiny.

What Is Corporate Valuation?

Corporate valuation is the process of determining the economic value of a company or a specific ownership interest in that company.

For a publicly traded business, market prices may provide an observable reference point. A privately held company is different. Its shares may not have an active market, and the ownership interest may have restrictions that affect how a hypothetical buyer would view the investment.

The valuation professional therefore considers the company's financial performance, assets, earning capacity, industry, ownership structure, market conditions and other relevant factors. The analysis should be tailored to the purpose of the assignment rather than relying on a standard formula.

Why Does the Purpose of the Valuation Matter?

The same business can produce different valuation conclusions depending on the question being answered.

An estate valuation may focus on the fair market value of a decedent's ownership interest for tax purposes. A divorce valuation may focus on the value of a business interest under the laws and case precedent applicable to the proceeding. A commercial litigation assignment may instead focus on the economic loss associated with a particular event.

This is why attorneys should identify the purpose, standard of value, premise of value and valuation date before the valuation work begins.

Valuation Situation

Common Focus

Key Issue

Estate

Value of closely held interest

Applicable tax valuation standard

Divorce

Business or ownership interest

State-specific valuation rules

Litigation

Economic value or damages

Legal theory and relevant date

Shareholder dispute

Ownership interest

Rights and restrictions

Transaction

Negotiated business value

Buyer/seller assumptions

These categories can overlap, but the valuation question should always be clearly defined before the analysis is performed.

Corporate Valuation for Estate and Estate Tax Matters

When a closely held business represents part of an individual's estate, its value may become relevant for federal estate tax purposes.

The IRS generally defines fair market value around the concept of a hypothetical transaction between a willing buyer and willing seller, with neither party being under compulsion and both having reasonable knowledge of the relevant facts.

For privately held companies, there may be no quoted market price to establish that value. The valuation therefore requires consideration of financial information and other circumstances affecting the business and the ownership interest.

This is where Rev. Rul. 59-60 becomes particularly relevant. The ruling explains that valuation of closely held stock requires consideration of available financial data and relevant factors affecting fair market value, and it specifically recognizes that there is no single formula that applies to every valuation situation.

What Is Rev. Rul. 59-60?

Revenue Ruling 59-60 is a foundational IRS valuation framework for closely held stock when market quotations are unavailable or limited.

One of its most important principles is that a valuation cannot be reduced to a mechanical calculation. The ruling identifies general approaches and factors that should be considered, while recognizing that each business presents different circumstances.

Factors commonly considered include the company's history, financial condition, earning capacity, dividend-paying capacity, nature of the business, economic outlook, industry conditions, management and comparable securities.

The practical takeaway is important for attorneys: a valuation report should not merely mention Rev. Rul. 59-60. It should demonstrate how the relevant factors were considered and how they influenced the conclusion.

Key Factors That Can Affect an Estate Valuation

A closely held company's value can be influenced by several characteristics.

Financial Performance

Historical revenue, profitability, cash flow, margins and balance-sheet strength can help establish the company's financial profile. However, historical results should not automatically be treated as a forecast of future performance.

Earning Capacity

A valuation may consider the company's ability to generate future economic benefits. Sustainable earnings can be more relevant than an unusually strong or weak year that does not represent normal operations.

Industry and Economic Conditions

Industry growth, competition, interest rates, regulation, customer demand and broader economic conditions can affect the outlook for the business.

Ownership Interest

The value of a controlling interest may differ from the value of a minority interest because the rights attached to ownership can differ.

Marketability

A privately held interest may not be as easily sold as publicly traded stock. The characteristics of the specific interest and the applicable standard can therefore affect the valuation analysis.

The IRS's valuation materials emphasize consideration of relevant financial and business information rather than reliance on a single valuation formula.

Corporate Valuation in Divorce Proceedings

Business interests can become some of the most complicated assets in a divorce case, particularly when one spouse owns a closely held company.

The first issue is often determining which portion of the business is subject to division under applicable state law. The valuation professional may then need to determine the value of the relevant interest using the standard required by the jurisdiction or court.

The analysis can involve more than the company's reported profit. Owner compensation, personal expenses paid by the business, related-party transactions, excess assets, shareholder loans and business or personal goodwill may all become relevant depending on the case.

Fair Value vs. Fair Market Value in Divorce

One of the most important distinctions in divorce-related valuation is the difference between fair value and fair market value.

These terms should not automatically be treated as interchangeable. Their meaning can depend on the governing statute, jurisdiction and case law.

Fair market value generally uses a hypothetical buyer-and-seller framework. Fair value may have a different legal meaning in a particular jurisdiction, especially in disputes involving closely held corporations.

This distinction can become significant when considering valuation discounts. Whether a discount for lack of control or lack of marketability is appropriate can depend on the applicable legal standard and the specific facts of the case.

For this reason, the valuation professional should receive clear instructions regarding the applicable legal standard from counsel.

Divorce Valuation: What Financial Information Matters?

A business valuation for divorce may require detailed financial records rather than simply the latest tax return.

Depending on the circumstances, the valuation professional may review:

  • Business tax returns

  • Financial statements

  • General ledgers

  • Payroll information

  • Owner compensation

  • Distributions

  • Related-party transactions

  • Business debt

  • Accounts receivable and payable

  • Fixed assets

  • Personal expenses paid through the company

  • Ownership agreements

The purpose is to understand the actual economic performance of the company and identify items that may require normalization or further analysis.

For example, an owner's compensation may be significantly different from market compensation for the role performed. The valuation professional may need to analyze whether an adjustment is appropriate before determining normalized earnings.

Corporate Valuation in Commercial Litigation

Valuation can also become central to commercial disputes involving shareholders, partnerships, contracts, business interruptions and alleged financial losses.

In litigation, the valuation question should be connected directly to the legal claim. The expert may be asked to determine the value of an ownership interest, calculate diminution in value or analyze economic damages.

The relevant valuation date can also be different from the date of the report. A company may have experienced significant changes after the event at issue, but those later developments do not automatically belong in the analysis.

This makes the distinction between known information, subsequent events and information that reflects conditions existing on the valuation date particularly important.

Why the Valuation Date Matters

The value of a business is not static.

Revenue can increase or decline. A major customer may leave. Debt may change. A new competitor may enter the market. The company may sign a major contract or experience a management transition.

For that reason, a valuation conclusion should clearly identify the valuation date.

In an estate matter, the applicable date is determined under the relevant tax rules. In a divorce matter, the date may be established by state law or court direction. In litigation, the relevant date may be tied to the alleged event, loss or another legally significant point in time.

A valuation prepared using today's financial information does not automatically establish what the business was worth several years earlier.

Choosing the Right Valuation Approach

A valuation professional may consider one or more of three broad approaches:

Valuation Approach

General Concept

When It May Be Useful

Income Approach

Value based on expected economic benefits

Businesses with meaningful earnings or cash-flow capacity

Market Approach

Uses evidence from comparable companies or transactions

Industries with useful market data

Asset Approach

Focuses on assets and liabilities

Asset-intensive or holding businesses

The appropriate approach depends on the nature of the company and the assignment.

A profitable operating company may support an income-based analysis, while an asset-heavy business may require significant consideration of its underlying assets. Market evidence can provide another indication when sufficiently comparable companies or transactions are available.

Using multiple approaches does not mean averaging the results automatically. The valuation professional needs to determine which indications are meaningful and how they should influence the final conclusion.

Income Approach

The income approach considers the economic benefits that the business is expected to generate.

Depending on the circumstances, this can involve capitalization of normalized earnings or a discounted cash flow analysis.

The quality of the underlying forecast is critical. A projection that assumes unusually high growth without supporting evidence may produce an inflated indication of value. Conversely, a forecast that ignores known business improvements may understate value.

The valuation professional therefore needs to understand the company's historical performance, future expectations and the assumptions supporting those expectations.

Market Approach

The market approach considers evidence from comparable publicly traded companies or transactions involving similar businesses.

The challenge for private companies is finding genuinely comparable information.

Differences in size, growth, profitability, customer concentration, geography, capital requirements and business model can make an apparently similar company economically different.

A strong market approach therefore requires more than selecting a convenient multiple. The valuation professional should explain why the selected comparables are relevant and how differences between them and the subject company were considered.

Asset-Based Approach

The asset-based approach focuses on the value of a company's assets after considering its liabilities.

This approach can be particularly relevant for companies whose value is closely connected to their underlying assets, such as holding companies or certain asset-intensive businesses.

For an operating company where future earning capacity represents a significant component of value, an asset-based approach alone may not fully capture the economics of the business.

The appropriate treatment depends on the characteristics of the company and the purpose of the assignment.

Control and Minority Interests

The ownership interest being valued matters.

A shareholder with control may have the ability to influence management decisions, distributions, strategic direction and the sale of company assets. A minority shareholder may have significantly fewer rights.

Consequently, the value of a controlling interest and the value of a minority interest are not necessarily identical.

The valuation professional must understand the company's governing documents, shareholder agreements and the specific rights attached to the interest being valued.

Discounts for Lack of Marketability and Lack of Control

Valuation discounts can become a significant issue in estate and litigation matters.

A discount for lack of marketability may reflect the characteristics of an ownership interest that cannot be readily sold in a public market. A discount for lack of control may reflect the reduced economic or governance rights associated with a non-controlling interest.

However, these discounts are not automatic.

Whether a particular discount is appropriate depends on the applicable standard of value, legal framework, characteristics of the ownership interest and supporting valuation evidence.

This is another area where estate, divorce and litigation assignments can produce materially different questions.

What Courts and the IRS Examine in a Valuation

A valuation report may receive scrutiny from attorneys, opposing experts, judges, regulators or the IRS.

Several questions are likely to matter:

  • Was the correct valuation date used?

  • Is the standard of value clearly identified?

  • Does the methodology fit the assignment?

  • Are the financial records reliable?

  • Were unusual financial items normalized appropriately?

  • Are projections supported by evidence?

  • Are comparable companies genuinely comparable?

  • Are ownership rights clearly understood?

  • Are discounts supported?

  • Can the expert explain the assumptions?

  • Does the conclusion remain reasonable when challenged?

For tax-related valuations, the IRS specifically expects relevant financial data and factors affecting fair market value to be considered. Its examination guidance also directs reviewers to examine items such as governance documents, tax filings and the taxpayer's appraisal when evaluating valuation issues.

Documentation Matters

A defensible valuation depends heavily on the quality of the underlying evidence.

The valuation professional may require financial statements, tax returns, ownership agreements, capitalization information, debt schedules, customer information, management details and other business records.

Good documentation allows the expert to connect the conclusion to observable facts.

It also helps attorneys understand which assumptions are factual, which are professional judgments and which depend on the legal framework of the case.

Common Weaknesses in Litigation-Related Valuations

Some valuation disputes arise not because the valuation method itself is inherently inappropriate, but because the assumptions behind it are weak.

For example, an expert may rely heavily on a forecast that management cannot substantiate. Another valuation may use a set of market comparables that differ substantially from the subject company.

Other potential weaknesses include inconsistent treatment of owner compensation, unsupported discounts, insufficient analysis of non-operating assets or failure to explain why one valuation method was preferred over another.

A defensible report should anticipate these questions rather than simply present a final value.

How Attorneys Can Prepare for a Valuation Assignment

Attorneys can make the valuation process more efficient by defining the legal and valuation questions before the expert begins the analysis.

Start by identifying the purpose, valuation date, standard of value, ownership interest and relevant legal assumptions.

Then provide the valuation professional with the key documents and explain any known disputes or unusual circumstances surrounding the business.

Early communication between counsel and the valuation professional can also help identify information gaps before they become major issues during deposition or trial.

Role of an Independent Valuation Professional

An independent valuation professional provides an analysis based on financial evidence, valuation principles and the defined purpose of the engagement.

For attorneys, independence can be particularly important when the valuation is expected to face scrutiny from another expert or the court.

The professional should be able to explain not only the final conclusion but also the reasoning behind the selected methodology, adjustments, assumptions and valuation discounts.

The goal is not to produce the highest or lowest possible value. The goal is to develop a conclusion that is appropriately supported by the facts and consistent with the assignment.

Conclusion

Corporate valuation in estate, divorce and litigation matters requires more than applying a financial formula to a company's revenue or earnings.

The applicable standard of value, valuation date, ownership interest, legal framework and purpose of the assignment can all affect the analysis. In estate tax matters, Rev. Rul. 59-60 provides an important framework for considering the relevant facts and valuation factors, while divorce and litigation assignments may require analysis under different jurisdiction-specific standards.

For attorneys, the strongest valuation is one where the methodology and assumptions can be clearly explained, supported by evidence and connected to the legal question being addressed.
