Which of the following actions require a policyowner to provide proof of insurability in an Adjustable Life policy?

In an Adjustable Life policy, when a policyowner seeks to increase the face amount of insurance coverage, it is essential to provide proof of insurability. This requirement exists because increasing the face amount elevates the level of risk that the insurer must underwrite. The insurance company needs to assess the policyowner's current health status and any other factors that could affect their insurability.

By requiring proof of insurability, such as a medical examination or health questionnaire, the insurer can make informed decisions about the additional coverage and determine whether the increased risk is acceptable. This step helps ensure that the insurer can manage their risk while also providing appropriate coverage to the policyowner.

Actions like changing premium payment methods, transferring policy ownership, or adjusting investment options typically do not involve a change in the level of risk and thus do not require proof of insurability. These changes are more administrative or operational in nature rather than fundamentally altering the terms of the coverage in a way that impacts underwriting risk.
