What is NOT considered to be a common life insurance nonforfeiture option?

A life income annuity is not considered a common nonforfeiture option because it represents a payout option rather than a method of maintaining some form of life insurance coverage when premiums are no longer paid. Nonforfeiture options are designed to provide policyholders with alternatives to forfeiting their policy, allowing them to retain some benefits even if they discontinue premium payments.

The other options mentioned are indeed common nonforfeiture options. Extended term insurance allows the policyholder to convert their whole life policy into term insurance for a specific period, while reduced paid-up insurance allows for a reduced amount of coverage to remain in force without the need for further premium payments. The cash surrender value provides policyholders the opportunity to cash in the policy for its accumulated value, further emphasizing the focus on preserving some benefit from the policy.
