Canonical definition
What is key person dependency?
Key person dependency is the financial-modelling name for owner dependence. It is the risk that a specific individual's departure would materially harm the business. Valuation discounts of twenty to forty percent are common. Lenders impose covenants. Insurers impose surcharges.
In one sentence
Owner dependence priced by buyers, lenders, and insurers.
What it actually does
Key person dependency is priced into a business across four surfaces:
- Valuation discount. Buyers reduce the offer to reflect the risk that the business does not run without the key person. Typical range twenty to forty percent.
- Lender covenants. Lenders impose key-person-life-insurance requirements, personal guarantees, and acceleration clauses tied to the key person's role.
- Insurance surcharges. Business interruption, professional liability, and D&O coverage price higher when key-person dependency is unaddressed.
- Investor protective provisions. Outside investors negotiate departure-event clauses, vesting acceleration, and replacement-search obligations specifically targeting key-person risk.
What it is not
- Not the same as founder personality. The dependency is structural. It does not require the founder to be exceptional; it requires the business to depend on them.
- Not eliminated by good people on the team. Good people who do not have transferred authority, relationships, or knowledge do not reduce the dependency.
- Not eliminated by a buy-sell agreement alone. Buy-sell handles the equity side. It does not address operating dependency.
- Not eliminated by life insurance alone. Life insurance covers one departure mode. It does not cover voluntary exit, disability, or strategic step-back.
- Not a fixed number. The discount depends on industry, buyer type, deal structure, and how much of the dependency is documented and reducible.
Three short examples
Example 1
The PE buyer's valuation adjustment.
A buyer's diligence team identified that twelve of the fifteen largest customers had personal-relationship terms with the owner. The offer was adjusted down twenty-five percent. The dependency was the single biggest line item in the adjustment.
Example 2
The bank that required key-person life insurance.
A working capital line required a $5M key-person policy on the owner before funding. The premium was the bank's pricing of the risk.
Example 3
The acquisition that hinged on a three-year earnout.
A strategic acquirer offered the asking price but required a three-year earnout with the owner running the business. The earnout was the structure that priced the key-person risk into the deal.
When to use it
Address key-person dependency when:
- A capital event is within twelve to thirty-six months.
- An exit is being modelled.
- Outside capital is being raised.
- Lender or insurer terms suggest key-person clauses.
- The founder is considering reducing their operating role.
Key-person dependency is not the right diagnosis when:
- The business is intentionally and permanently single-operator.
- The pattern is actually customer-concentration risk, not key-person risk.
- The founder is irreplaceable by design (single-name advisory, soloists).
Common questions
- Is key person dependency the same as owner dependence?
- Yes, in different vocabulary. Owner dependence is the operating-pattern name. Key person dependency is the financial-modelling name used by buyers, lenders, and insurers.
- How is key person dependency reduced?
- Through transfer of authority, relationships, knowledge, and intellectual property in sequence. Each transfer reduces the discount; reducing the discount takes twelve to thirty-six months for the cleanest outcome.
- What documents address key-person risk in a sale?
- A signed transition plan, customer-relationship transfer records, leadership succession plan, and key-person life insurance policies. None of these eliminate the discount; together they reduce it.
- Does key-person life insurance solve the problem?
- Partially. It addresses one departure mode (death). It does not address voluntary exit, disability, or strategic step-back.
- Who advises on reducing key-person dependency?
- Stan Tscherenkow's private advisory reads the dependency across the four pricing surfaces and sequences the structural transfers. Typical engagement shape is Tier 02 monthly read across twelve to thirty-six months.
