On a date to be specified by the commissioner of agriculture, the president and secretary of any fair, or agricultural society wishing to share in state aid to fairs as provided for under §43-21-102, shall file with the commissioner a sworn statement of premiums to be paid during the current fair season for entries outlined in §43-21-106. In addition thereto and together with sworn statement, the president and secretary shall also show correctly the exact amount paid in premiums for the same entries in the preceding fair season. State aid on the basis of premiums paid during the preceding fair season will be allocated by the commissioner for the current fair season. Whenever any fair did not operate during the preceding fair season, the commissioner is authorized in that instance alone to make an allocation of state aid based upon the estimate of premiums to be paid during the current fair season.
