Permanent life insurance is life insurance that remains in force (in-line) until the policy matures (pays out), unless the owner fails to pay the premium when due (the policy expires OR policies lapse). The policy cannot be canceled by the insurer for any reason except fraud in the application, and that cancellation must occur within a period of time defined by law (usually two years). Permanent insurance builds a cash value that reduces the amount at risk to the insurance company and thus the insurance expense over time. This means that a policy with a million dollar face value can be relatively expensive to a 70 year old. The owner can access the money in the cash value by withdrawing money, borrowing the cash value, or surrendering the policy and receiving the surrender value.
The four basic types of permanent insurance are whole life, universal life, limited pay and endowment.
