For the purposes of this subsection, a "market" means the total direct written insurance premium of all insurers providing insurance in Indiana for a particular line of business, as reported in the annual statements required to be filed by insurers licensed to do business in Indiana.
Before the end of the waiting period, the commissioner, on a one-time basis, may require the submission of additional needed information relevant to the proposed acquisition. If the commissioner requests additional information under this subsection, the waiting period ends on the earlier of the thirtieth day after receipt of the additional information by the commissioner or the termination of the waiting period by the commissioner.
For the purposes of this subdivision, a highly concentrated market is a market in which the share of the four (4) largest insurers is seventy-five percent (75%) or more of the market. Percentages not referred to in this subdivision must be interpolated proportionately to the percentages that are referred to in this subdivision. If more than two (2) insurers are involved in a proposed acquisition, exceeding the total of the two (2) figures set forth for insurer A and insurer B in an item set forth in this subdivision is prima facie evidence of violation of the competitive standard set forth in subsection (g). For the purpose of this subdivision, the insurer with the largest share of the market shall be considered to be insurer A.
Every order shall be accompanied by a written decision of the commissioner setting forth the commissioner's findings of fact and conclusions of law.
