§ 92. Payment of premiums. 1. Workers' compensation insurance premiums
for any policy period shall be paid into the state insurance fund at the
beginning of the period when the amount of such premium is less than one
thousand dollars according to the estimated expenditure of wages for the
period except to the extent that rules of the commissioners permit such
amount to be paid by installments. For all other policyholders, workers'
compensation insurance premiums for any policy period based on an
estimated expenditure of wages for the period may, at the policyholders'
option, be paid into the state insurance fund by installments in
accordance with rules promulgated by the commissioners.

2. Disability benefits insurance premiums for any period shall be paid
into the state insurance fund at the beginning of the period according
to the estimated expenditure of wages for the period except to the
extent that rules of the commissioners permit such amount to be paid by
installments.

3. At the end of the period an adjustment of the premium shall be made
according to the actual expenditure of wages. If such adjusted premium
is more than the premium paid at the beginning of the period, the
policyholder shall pay the difference immediately upon notification of
the amount due except to the extent that rules promulgated by the
commissioners permit such amount to be paid by installments. If such
adjusted premium is less than the premium paid in advance, the state
insurance fund shall, at the policyholder's option, either refund the
difference or credit the amount thereof to the policyholder's account
with the state insurance fund.
