The term “cost to the wholesaler” shall mean the “basic cost of cigarettes and tobacco products” to the wholesaler plus the “cost of doing business by the wholesaler”, as evidenced by the recognized statistical and cost accounting practices in allocation of overhead costs and expenses, paid or incurred, and must include, without limitation, labor costs (including salaries or drawing accounts of owners, salaries of executives and officers, or general and special allocations and charges made by parent organizations), rent, depreciation, selling costs, maintenance of equipment, delivery costs, all types of licenses, taxes, insurances, and advertising, and any other cost.

b. In the absence of proof of a lesser cost of doing business by the wholesaler making the sale, the “cost of doing business by the wholesaler” shall be presumed to be two percent (2%) of the “basic cost of cigarettes and tobacco products” to the wholesaler, plus cartage to the retail trade, if performed or paid for by the wholesaler, which cartage cost, in the absence of proof of a lesser cost, shall be deemed to be three-fourths of one percent (3/4 of 1%) of the “basic cost of cigarettes and tobacco products” to the wholesaler.
