(1) in the case of any contract of life insurance or life annuity, paying bonuses to policyholders or otherwise abating their premiums in whole or in part out of surplus accumulated from nonparticipating insurance, provided that any such bonuses or abatement of premiums shall be fair and equitable to policyholders and for the best interests of the insurer;
(2) in the case of life insurance policies issued on the industrial debit, preauthorized check, bank draft, or similar plans, making allowance to policyholders who have continuously for a specified period made premium payments directly to an office of the insurer or by preauthorized check, bank draft, or similar plans, in an amount which fairly represents the saving in collection expense;
(3) readjustment of the rate of premium for a group insurance policy based on the loss or expense experience thereunder, at the end of the first or any subsequent policy year of insurance thereunder, which may be made retroactive only for such policy year;
(4) reduction of premium rate for policies of large amount but not exceeding savings in issuance and administration expenses reasonably attributable to such policies as compared with policies of similar plan issued in smaller amounts;
(5) issuing life or disability insurance policies on a salary savings or payroll deduction plan at reduced rate reasonably commensurate with the savings made by the use of such plan.
