Business Disability (Key Person, Buy-Sell, BOE)

Key Takeaways

  • Key person DI is owned by and paid to the business to replace revenue and fund a replacement when a critical employee is disabled; the employee is only the insured.
  • Disability buy-sell funds the purchase of a disabled owner's interest and uses a long (12–24 month) elimination period to confirm permanence before triggering the buyout.
  • Business Overhead Expense reimburses fixed operating costs (rent, non-owner salaries, utilities) up to a monthly cap on an actual-expense basis with a short (15–30 day) elimination period.
  • BOE never covers the disabled owner's own salary, personal expenses, profits, or inventory — those belong to an individual DI policy.

Why Businesses Need Disability Coverage

A disability can damage a business as severely as the death of an owner or critical employee. Three core business DI products address distinct exposures: Key Person (Key Employee) disability, Disability Buy-Sell, and Business Overhead Expense (BOE). Each has a different policyowner, premium payer, beneficiary, and tax treatment, and the exam tests these distinctions directly.

Key Person Disability Insurance

Key person DI protects the business against the economic loss caused when a critical employee — a top producer, lead engineer, or rainmaker — becomes disabled.

  • Policyowner / premium payer / beneficiary: the business.
  • Insured: the key employee.
  • Purpose: replace lost revenue, fund a temporary replacement, and cover recruiting/training of a successor.
  • Benefits are paid to the business as a lump sum or monthly amount and help the firm stay solvent during the transition.

The business chooses the benefit amount based on the employee's contribution to revenue, not the employee's salary alone. Because the benefit funds the company's recovery rather than the employee's livelihood, the employee's consent to be insured is required but the employee has no ownership of the policy and collects nothing directly.

Key person DI usually carries a moderate elimination period (60–90 days) and a moderate benefit period (one to two years) — long enough to recruit and onboard a replacement, but not lifetime, because the goal is bridging a transition, not permanently replacing the employee. Contrast this with key person life insurance, which pays a death benefit; key person disability pays while the insured is alive but unable to contribute.

Disability Buy-Sell Insurance

A buy-sell agreement is a contract among business owners specifying that if an owner leaves — through death, retirement, or disability — the remaining owners (or the entity) will purchase that owner's share at a predetermined price. Disability buy-sell insurance funds the purchase when an owner becomes totally disabled.

Key features:

  • Uses a long elimination period (commonly 12 to 24 months) to confirm the disability is permanent before triggering the buyout — you do not want to buy out an owner who recovers in three months.
  • Typically pays the buyout as a lump sum or in installments.
  • Prevents a disabled, non-working owner from continuing to draw profits while contributing nothing, which protects the active owners.

Business Overhead Expense (BOE) Insurance

Business Overhead Expense insurance reimburses the fixed operating expenses of a small business when the owner is disabled, so the doors can stay open until the owner recovers or the business is sold. BOE is essential for solo professionals — dentists, attorneys, accountants — whose practice generates no revenue when they cannot work but still incurs rent and staff costs.

What BOE Covers and Does Not Cover

Covered (deductible overhead)NOT covered
Rent or mortgage interestThe owner's own salary or draw
Employee salaries (non-owner)Owner's personal living expenses
Utilities, telephone, internetProfit / loss replacement
Equipment leases / depreciationInventory or cost of goods
Property taxes, insurance premiumsNew capital purchases

The defining trap: BOE does NOT cover the disabled owner's own salary — that is what an individual DI policy is for. BOE only covers the fixed expenses needed to keep the office running.

BOE Mechanics

  • Reimbursement basis: Unlike personal DI, BOE pays actual covered expenses up to the monthly limit — it is reimbursement, not a flat indemnity. If actual overhead is below the monthly cap, some policies extend the benefit period using the unused amount.
  • Short elimination period: typically 15–30 days, because bills come due quickly.
  • Short benefit period: typically 12–24 months — long enough to recover or arrange a sale.

Worked Example — BOE Reimbursement

Dr. Okafor's BOE policy has a $10,000 monthly maximum. While disabled, her actual covered overhead (rent, two staff salaries, utilities, equipment lease) totals $7,500 in a month. BOE reimburses $7,500, not $10,000, because it pays actual expenses up to the cap. Her own would-be salary of $12,000 is not covered by BOE — she relies on her individual DI policy for that.

Exam Traps for Business Disability

  • BOE never pays the owner's salary — only fixed business overhead. This is the single most tested BOE point.
  • BOE is reimbursement (actual expenses up to a cap); individual DI is a flat indemnity amount.
  • Disability buy-sell uses a long elimination period (12–24 months) to confirm permanence before triggering a buyout; BOE uses a short one (15–30 days).
  • Key person insurance names the business as owner, payer, and beneficiary; the key employee is merely the insured and receives nothing directly.
  • Match the product to the exposure: revenue loss = key person; ownership transfer = buy-sell; keeping the lights on = BOE.

Worked Example — Matching Product to Need

A three-partner architecture firm wants full protection if any partner is disabled. They need three coordinated products: (1) BOE so the firm's rent, drafting software leases, and admin staff salaries continue to be paid; (2) a disability buy-sell policy on each partner so the other two can purchase a permanently disabled partner's one-third interest at the agreed price after a 12-month elimination period; and (3) individual DI on each partner personally to replace each partner's own lost salary, since neither BOE nor buy-sell covers an owner's paycheck. A single product cannot solve all three exposures.
