The minimum mark-ups established by the board shall be fair and reasonable to licensed retailers and the ultimate consumer. Such mark-ups must be in the public interest and such that they do not unduly stimulate the sale and consumption of alcoholic liquor or tend to disrupt the orderly sale and distribution of alcoholic liquor. The board in establishing minimum mark-ups shall take into consideration and be guided by the following: (a) The mean of acquisition costs of licensed retailers; (b) federal, state and local taxes and license fees which are paid by retailers and are levied or imposed in connection with their business of selling alcoholic liquor in this state; (c) the mean of selling costs of licensed retailers; (d) the mean of any legitimate, reasonable expense not hereinbefore specified, incurred in the legal conduct of licensed retailers’ businesses; and (e) a reasonable profit for licensed retailers. The board may base its determination of the mean of retailers’ acquisition costs, selling costs and operating expenses on a sampling of retailers generally representative of all retailers in the state. To insure that retailers in this state receive only a reasonable mark-up and profit, the alcoholic beverage control board of review, within six (6) months after the effective date of this act, shall conduct and complete studies to determine whether the present minimum mark-ups prescribed for licensed retailers should be maintained as currently established, increased or decreased. Until such studies are completed, the minimum mark-ups in effect immediately prior to the effective date of this act shall remain in effect.
