Me. Rev. Stat. tit. 24-A, § 703

For the purposes of this Title, an "annuity" is a contract under which obligations are assumed with respect to periodic payments for a specific term or terms or where the making or continuance of all or of some of the payments, or the amount of a payment, is dependent upon the continuance of human life, except payments made pursuant to optional modes of settlement under the authority of section 702. A contract that includes extra benefits of the kinds defined in sections 702 and 704 is deemed to be an annuity, if the extra benefits constitute a subsidiary or incidental part of the entire contract. A charitable gift annuity agreement, as defined in section 703‑A, is not insurance.
