Buy-Sell Agreements: Protecting the Family and the Business

A buy-sell agreement determines what happens when an owner dies, becomes disabled, wants to sell, or faces other triggering events. It provides certainty during emotionally difficult transitions—preventing disputes and ensuring business continuity.

Funding Mechanisms

Cash

Life Insurance

Key person policy

Installment Note

Structured payments

Without a buy-sell agreement, the death of a shareholder could leave their shares in the hands of a surviving spouse or heirs who have no involvement in the business. A divorce could transfer ownership to an ex-spouse. A partner who wants out might sell to a competitor or unwanted outsider.

A buy-sell agreement addresses these scenarios proactively—while everyone is healthy, relations are good, and rational decisions can be made. It's essentially a prenuptial agreement for business partners.

Why Buy-Sell Agreements Matter

Buy-sell agreements provide: liquidity for exiting shareholders or their estates, protection against unwanted co-owners, pre-determined valuation methodology, funding mechanisms for buyouts, and clarity during emotional transitions. Every business with more than one owner should have one.

Trigger Events

Buy-sell agreements specify which events trigger the buyout provisions:

Death

When a shareholder dies, their ownership passes to their estate. The agreement typically requires or permits the company or other shareholders to purchase the deceased's shares, preventing heirs from becoming involuntary business partners.

Disability

A shareholder who becomes permanently disabled may no longer be able to contribute. The agreement should define disability (usually tied to inability to perform job duties for a specified period) and trigger buyout provisions.

Retirement

When a shareholder retires, the agreement may require or permit buyout. Define retirement age or criteria and the process for transitioning ownership.

Voluntary Departure

A shareholder who leaves the company voluntarily (resignation, career change) may trigger buyout provisions. Consider whether the price should differ for voluntary vs. involuntary departures.

Termination for Cause

If a shareholder is terminated for cause (fraud, misconduct, breach of fiduciary duty), the agreement may provide for buyout at a discounted price.

Divorce

In many states, business ownership is marital property. The agreement should address what happens if shares would otherwise transfer to an ex-spouse—typically requiring buyout at fair value rather than allowing the ex-spouse to become an owner.

Bankruptcy

If a shareholder goes through personal bankruptcy, their shares could be claimed by creditors. The agreement should provide a buyout right to keep ownership within the family or existing shareholders.

Types of Buy-Sell Agreements

Cross-Purchase Agreement

Individual shareholders agree to purchase shares from a departing shareholder or their estate.

  • Pros: Surviving shareholders get stepped-up basis; simpler for estate tax
  • Cons: Complex with many shareholders; each shareholder needs insurance on each other
  • Best for: Two or three shareholders of roughly equal ownership

Redemption Agreement (Entity Purchase)

The company (not individual shareholders) agrees to redeem shares from a departing shareholder.

  • Pros: Simpler administration; company owns one policy per shareholder
  • Cons: No stepped-up basis for remaining shareholders; potential AMT issues
  • Best for: Multiple shareholders; unequal ownership; C-corporations

Hybrid Agreement

Combines elements of both—company has first option to redeem; if it declines, shareholders can purchase cross-purchase.

  • Pros: Flexibility; can optimize for tax and practical considerations
  • Cons: More complex drafting
  • Best for: Larger family businesses; situations where optimal approach may vary by trigger event

Entity Type Matters

The optimal structure depends on your entity type (S-corp, C-corp, LLC, partnership), number of shareholders, relative ownership stakes, and tax situations. Work with an attorney and tax advisor to determine the best approach.

Valuation Methods

How shares will be valued is one of the most important provisions. Common approaches:

Fixed Value

Shareholders agree on a specific dollar value, typically reviewed and updated annually.

  • Pros: Simple, certain, no disputes about methodology
  • Cons: Often not updated; becomes stale as business grows
  • Caution: IRS may challenge if fixed value is significantly below fair market value

Formula-Based

Value determined by applying a formula (e.g., 5x trailing EBITDA, book value, etc.).

  • Pros: Updates automatically with financial performance
  • Cons: May not reflect true market value; vulnerable to manipulation
  • Consideration: Specify the formula clearly, including which financial statements to use

Appraisal

Independent appraiser determines fair market value when a trigger event occurs.

  • Pros: Most accurate; reflects current market conditions
  • Cons: Expensive ($15K-$50K); takes time; potential for disputes over appraiser selection
  • Recommendation: Specify appraiser selection process and standards to follow

Discounts

Will minority interest or marketability discounts apply? Consider:

  • Discounts are common in arm's-length transactions
  • IRS may challenge if discounts are used for estate tax but not buy-sell
  • Determine in advance whether discounts apply and their approximate level

Consistency with Estate Planning

The IRS looks at whether buy-sell valuation is consistent with estate tax valuation. If the buy-sell uses a low formula value but the estate claims fair market value for estate tax, expect scrutiny. Coordinate your buy-sell agreement with estate planning to ensure consistency.

Funding Mechanisms

How will the buyer fund the purchase? The agreement should address funding sources:

Life Insurance

Life insurance provides immediate liquidity upon death—the most common funding for death triggers.

  • Policy ownership depends on agreement type (individual for cross-purchase, company for redemption)
  • Coverage should match current valuation (review annually)
  • Consider insurability issues (health, age)
  • Coordinate beneficiary designations with agreement

Disability Insurance

Disability buy-out insurance provides funds when a shareholder becomes disabled. These policies typically have a waiting period (12-24 months) before paying out.

Company Funds

The company uses operating cash or retained earnings. Works well for smaller buyouts but may strain cash flow for larger transactions.

Installment Payments

Payments over time (typically 3-10 years) reduce immediate cash burden:

  • Specify payment terms, interest rate, and security
  • Consider what happens if buyer defaults
  • Departing shareholder takes credit risk

Bank Financing

Buyer obtains a loan to fund the purchase. The company or individual may need to secure the loan.

Insurance Coverage Gap

A common problem: insurance coverage was set years ago and no longer reflects current business value. If the business has doubled in value since insurance was purchased, the estate may receive only half the shares' value. Review coverage annually when valuation is updated.

Other Key Provisions

Right of First Refusal

Before selling to an outsider, the shareholder must offer shares to the company or other shareholders at the same price and terms.

Drag-Along Rights

If majority shareholders agree to sell the company, they can require minority shareholders to sell on the same terms.

Tag-Along Rights

If a majority shareholder sells, minority shareholders can participate in the sale on the same terms.

Permitted Transfers

Specify transfers that don't trigger buyout provisions—typically transfers to family trusts, to spouses, or between generations for estate planning purposes.

Non-Compete

Departing shareholders may be restricted from competing for a specified period and geographic area.

Maintaining the Agreement

  • Annual review: Review and update valuation at least annually
  • Insurance check: Confirm insurance coverage matches current valuation
  • Life events: Update when shareholders join, leave, or ownership changes
  • Business changes: Review after major transactions, growth, or value changes
  • Legal review: Have attorney review periodically for legal and tax changes
