Key Person Insurance

What Does Key Person Insurance Mean?
A life insurance policy that a company purchases on a key executive's life. The company is the beneficiary of the plan and pays the insurance policy premiums.

Investopedia explains Key Person Insurance
Key person insurance is needed if the sudden loss of a key executive would have a large negative effect on the company's operations. The payout provided from the death of the executive essentially buys the company time to find a new person or to implement other strategies to save the business.
