At any time funds are on hand for that purpose, the association has the right to redeem by lot or otherwise, as the board of directors may determine, all or any part of any of its savings accounts on an earnings date by giving thirty 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 may redeem any of its savings accounts when the association is in an impaired condition or when it has applications for withdrawal which have been on file for more than thirty days and have not been reached for payment. The redemption price of savings accounts redeemed must be the full value of the account redeemed, as determined by the board of directors, but in no event may the redemption price be less than the withdrawal value. If this notice of redemption has been given, and if on or before the redemption date the funds necessary for the redemption have been set aside so as 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 these accounts shall terminate after the redemption date, except the right of an account holder of record to receive the redemption price without interest. All savings account evidences of ownership evidencing former savings accounts which have been validly called for redemption must be tendered for payment within ten years from the date of redemption designated in the redemption notice; otherwise they must be canceled, the funds set aside for this account shall become the property of the State, and all claims of these former account holders against the association are barred forever.
