Advanced Insurance Strategies for Business Owners: Buy-Sell Agreements and Beyond

For businesses with more than one owner — partners, co-shareholders, family members who jointly own shares — one of the most consequential documents a business can have is one that, ideally, never needs to be referred to under pressure: a shareholder agreement that addresses what happens if an owner dies, becomes disabled, wants to sell their interest, or the business otherwise faces a change in ownership. The component of this addressing death, disability, or departure is often called a "buy-sell agreement."

What Triggers a Buy-Sell Provision

Valuation: How Will the Share Price Be Determined?

One of the most important — and most often vague — provisions in a buy-sell agreement is how the business will be valued when a triggering event occurs. Common approaches include:

• A formula — such as a multiple of earnings or revenue, applied to the most recent financial statements. Formulas are objective and avoid disputes over methodology, but a formula that made sense when the agreement was written may become less appropriate as the business changes over time, and benefits from periodic review.
• An independent valuation at the time of the triggering event — more accurate to the business’s actual value at that time, but introduces cost, time, and potential disagreement about which valuator or methodology to use, at a time when these disagreements are harder to resolve calmly.
• An agreed-upon value, updated periodically — owners agree on a value (perhaps annually, as part of an annual meeting), which then applies if a triggering event occurs before the next update. This requires discipline to actually update the value regularly, but provides certainty if a triggering event occurs.

Many buy-sell agreements use a combination — an agreed-upon value updated periodically, with a fallback to an independent valuation if the agreed value has not been updated within a certain period, addressing the risk of the agreed value becoming stale.

Funding the Buyout: Where Does the Money Come From?

Even with valuation and triggering events clearly defined, a buy-sell agreement is only as useful as the ability to actually fund the purchase when needed. This is where insurance most commonly enters the picture.

Life Insurance for the Death Trigger

As discussed in our companion article on corporate-owned life insurance, life insurance on each owner — with the proceeds designated to fund the buyout of that owner’s shares from their estate — is one of the most common funding mechanisms for the death trigger. The structure of how this insurance is owned and how proceeds are used (and the resulting Capital Dividend Account implications, covered in our companion article) depends on the specific buy-sell structure used (a "cross-purchase" arrangement, where owners individually own policies on each other, versus a "corporate-owned" or "promissory note" arrangement, where the corporation owns the policies and redeems the deceased’s shares).

Disability Insurance for the Disability Trigger

Buyout-specific disability insurance (distinct from personal disability insurance that replaces an individual’s income, discussed in our Women & Finance content) can provide a lump sum or structured payments specifically to fund a buyout if an owner becomes disabled and the agreement provides for a buyout in that circumstance. This is a less commonly addressed trigger than death, but can be equally significant — a disabled owner who can no longer contribute to the business, but whose shares are not bought out, can create an ongoing and difficult situation for the remaining owners.

Other Funding Approaches for Voluntary Departures

For voluntary departures (not triggered by death or disability), funding is more often addressed through a promissory note from the purchasing owner(s) to the departing owner, paid over time from future business earnings — insurance is generally not relevant to this trigger in the same way, since voluntary departure is not an insurable event.

Why "We’ll Figure It Out If It Happens" Does Not Work Well

Consider the death of one of two equal co-owners, without a buy-sell agreement in place. The deceased’s shares typically pass to their estate — meaning the surviving owner now potentially shares ownership of the business with the deceased’s spouse or other heirs, who may have no interest in or knowledge of the business, while the surviving owner continues to operate it. Negotiating a buyout in this situation — determining a value, agreeing on terms, arranging funding — is happening for the first time, under emotional circumstances, often with the involved parties having misaligned incentives (the surviving owner wants to pay less; the estate wants to receive more) and no pre-agreed framework to anchor the discussion.

A buy-sell agreement with insurance funding addresses this by having the valuation method and the funding already established before the triggering event — the death benefit is paid, the predetermined (or formula-based) value is applied, and the transaction proceeds according to terms that were agreed upon when all parties were able to negotiate calmly and with aligned long-term interests (since, at the time of drafting, any owner could be the one who dies, becomes disabled, or wants to leave — creating a natural incentive for fair terms).

Reviewing an Existing Agreement

For businesses that already have a buy-sell agreement — sometimes put in place years or decades earlier, often at the time the business was formed or a new partner joined — periodic review is worthwhile:

This Is a Coordination Exercise

A well-structured buy-sell arrangement typically involves a lawyer (drafting or reviewing the shareholder agreement itself), an insurance advisor (structuring the insurance to align with the agreement’s funding requirements), and an accountant or financial planner (addressing the tax implications of the chosen structure, including Capital Dividend Account considerations). These pieces need to align with each other — an agreement that specifies one funding structure while the actual insurance is owned and structured differently can create the very ambiguity and disputes the agreement was meant to prevent.
