Every holder of a wholesaler's license is entitled only to retain for himself or herself those profits in his or her business as are necessary to repair loss or shrinkage in his or her capital invested in the business plus nine percent (9%) per annum cumulatively upon the amount of capital actually invested in the business. All profits in excess of that amount shall be paid annually by the wholesaler to the treasurer of the state for its own use.
