Funding a Buy-Sell Agreement: Cross-Purchase vs. Entity-Purchase Insurance Structures

A buy-sell agreement is only as strong as the funding behind it. Here is how cross-purchase and entity-purchase structures differ, why life insurance remains the most dependable funding source, and why the agreement and the coverage need to be reviewed side by side.

A Promise on Paper Still Needs Cash Behind It

Most business owners with partners eventually sign a buy-sell agreement, a contract that sets out what happens to a shareholder's stake if they die, become disabled, or otherwise exit the business. The agreement itself is simply a set of promises: who has the right or obligation to buy, at what price, and under what trigger. None of that matters if the surviving owners cannot actually produce the cash to complete the purchase when the moment arrives. A funding mechanism is what turns the legal document into something that can be executed within days of a death, rather than years later after assets have been sold off or new debt has been negotiated under pressure.

Two Core Funding Structures: Cross-Purchase vs. Entity-Purchase

In a cross-purchase structure, each shareholder personally owns and is the beneficiary of a life insurance policy on each of their co-owners. When one owner dies, the surviving owners receive the death benefit directly and use it to buy the deceased's shares from their estate at the price or formula set out in the agreement. Because the purchase happens between individuals rather than through the company, the surviving owners' cost base in their now-larger shareholding typically increases by what they paid, which can matter when they eventually sell or wind down the business.

In an entity-purchase, or redemption, structure, the corporation itself owns the policies and is the beneficiary. On the death of a shareholder, the company receives the proceeds and uses them to redeem, or buy back and cancel, the deceased's shares directly from the estate. A private corporation can often credit much of a life insurance death benefit to its Capital Dividend Account, which can allow the redemption to be funded in a tax-efficient way at the corporate level, though the exact outcome depends on the policy and the corporation's circumstances and should always be confirmed with a tax advisor before the agreement is finalized.

• Number of owners: a cross-purchase can require a separate policy between every possible pair of shareholders, which becomes cumbersome past two or three owners, while an entity-purchase generally needs only one policy per owner
• Administration: entity-purchase centralizes policy ownership and premium payment inside the company, which is usually simpler to keep organized as ownership changes over time
• Cost base considerations: a cross-purchase can increase the surviving owners' personal cost base in their shares, while a redemption instead affects the company's own tax accounts
• Flexibility as shareholders change: adding or removing an owner is usually simpler under an entity-purchase, since the company adjusts the coverage rather than each individual shareholder

Why Life Insurance Outperforms a Sinking Fund or a Bank Loan

Some businesses try to fund a future buyout by setting aside cash in a sinking fund, gradually building a reserve out of retained earnings. The problem is timing: if an owner dies or becomes critically ill early in a ten-year savings plan, the fund is a fraction of what is needed, and the shortfall lands on the surviving owners and the deceased's family at the worst possible moment. A bank loan carries a similar gap, since lenders are naturally cautious about extending credit to a company that has just lost a key owner, and even where financing is available it adds debt and interest costs precisely when the business can least absorb them. Life insurance solves this timing problem directly, since the full, guaranteed death benefit is available the moment it is needed, regardless of how early the triggering event occurs.

The agreement and the insurance behind it are not a one-time exercise. As the business grows, a coverage amount that once matched the agreement's formula can quietly become inadequate, and a policy structured for one arrangement, say personal ownership for a cross-purchase, can be mismatched if the shareholders later restructure toward a redemption approach. Whenever the agreement is amended, a new owner joins, or the business is revalued, the underlying coverage amounts, ownership, and beneficiary designations should be checked against the agreement's actual terms, not assumed to still line up.
