(a) Fully paid certificates shall be payable at a date certain not less than ninety (90) days subsequent to the date of issue thereof, except that the company may pay such certificates prior to the maturity date whenever its reserve balance equals or exceeds the amount provided in section 13 of this chapter.  Such company may at any time redeem any of such certificates upon thirty (30) days notice in writing to the holder thereof prior to such redemption.  If such certificate is not presented for payment by the holder thereof at maturity, such certificate shall be payable thereafter only upon at least thirty (30) days notice in writing given by the holder thereof to the company issuing the same, except that any such company may waive such notice whenever its reserve balance equals or exceeds the amount provided in section 13 of this chapter.

(b) Installment certificates shall be payable only after ninety (90) days notice in writing given by the holder of the certificate to the company issuing the same, except that any such company may waive the notice whenever its reserve balance equals or exceeds the amount provided in section 13 of this chapter.  The company may at any time redeem any of the certificates upon thirty (30) days notice in writing to the holder of the certificate prior to such redemption.

(c) Subject to subsection (b), a company may permit the holder of any installment certificate of indebtedness or investment to make withdrawals from the certificate by negotiable or transferable instruments or orders, if the certificate is held by the type or category of holder permitted to hold a similar account with a financial institution controlled under 12 U.S.C. 3502.

(d) A company may require the owner of any installment certificate of indebtedness or investment which is subject to withdrawal by negotiable or transferable instruments or orders to maintain a minimum balance in that certificate of indebtedness or investment and may charge fees that are reasonable and competitive if the balance in the certificate of indebtedness or investment falls below a minimum required balance.  Interest paid on certificates of investment or indebtedness subject to withdrawal by negotiable or transferable instruments or orders may not exceed the maximum rate allowable for those financial institutions whose interest rates are controlled under 12 U.S.C. 3502.
