At any time funds are on hand for the purpose, the association shall have the right to redeem by lot as the board of directors may determine, all or any part of any of its savings accounts on an earnings date by giving thirty (30) days' notice by registered mail addressed to each affected account holder at his last address as recorded on the books of the association. No association shall redeem any of its savings accounts when the association is in an impaired condition or when it is unable to pay its applications for withdrawal. The redemption price of savings accounts redeemed shall be the full value of the account redeemed, as determined by the board of directors, but in no event shall the redemption price be less than the withdrawal value. If the aforesaid notice of redemption shall have been duly given, and if on or before the redemption date the funds necessary for such redemption shall have been set aside so as to be and continue to be available therefor, earnings upon the accounts called for redemption shall cease to accrue from and after the earnings date specified as the redemption date; and all rights with respect to such accounts shall forthwith, after such redemption date, terminate, except only for the right of the account holder of record to receive the redemption price with interest to the redemption date. All savings account books or certificates evidencing former savings accounts which have been validly called for redemption must be tendered for payment within ten (10) years from the date of redemption designated in the redemption notice, otherwise they shall be cancelled. After the expiration of the period of ten (10) years, the association in which the funds are located shall, within six (6) months, pay the funds to the commissioner, who shall deposit such funds to the department's account with the State Treasurer.
