Contract: A legal written agreement that becomes binding when signed.
Interest rate: The amount paid by a borrower to a lender in exchange for the use of the lender's money for a certain period of time.

(d)  The weighting factor for a single premium immediate annuity or for annuity benefits involving life contingencies arising from another annuity with a cash settlement option or from a guaranteed interest contract with a cash settlement option is.80.
(e)  The weighting factor for an annuity or a guaranteed interest contract, other than an annuity or contract to which Subsection (d) applies, is determined by the following tables:

(1)  a policy is a "Plan Type A" policy if:
(A)  the policyholder may withdraw funds at any time, but only:
(i)  with an adjustment to reflect changes in interest rates or asset values after the insurance company receives the funds;
(ii)  without an adjustment described by Subparagraph (i), provided that the withdrawal is in installments over five years or more; or

(ii)  the policyholder is not permitted to withdraw funds; and
(B)  on the expiration of the interest rate guarantee, the policyholder may withdraw funds in a single sum or in installments over less than five years, without an adjustment described by Paragraph (A)(i); and
(3)  a policy is a "Plan Type C" policy if the policyholder may withdraw funds before the expiration of the interest rate guarantee in a single sum or in installments over less than five years:
(A)  without an adjustment to reflect changes in interest rates or asset values after the insurance company receives the funds; or
(B)  subject only to a fixed surrender charge that is a percentage of the fund stipulated in the contract.
