As used in the Arkansas Insurance Code, unless the context otherwise requires, a "stipulated premium plan insurer" is one issuing policies or certificates promising money or other benefits to a member or policyholder upon his or her disability or, upon his or her decease, to his or her legal representatives or beneficiaries designated by him or her, which money or benefit is derived from stipulated premiums collected in advance from those members or policyholders and from interest and other accumulations, and which insurer was not required, prior to January 1, 1960, to set aside a fixed policy reserve such as is required of legal reserve insurers.
