Segment Reporting [Abstract] |
Segment Information | SEGMENT INFORMATION We have two reportable business segments in our operations: property and casualty insurance and life insurance. The property and casualty insurance segment has seven domestic locations from which it conducts its business. The life insurance segment operates from our home office in Cedar Rapids, Iowa. Because all of our insurance is sold domestically, we have no revenues from foreign operations. We evaluate the two segments on the basis of both statutory accounting principles prescribed or permitted by our states of domicile and GAAP. We analyze results based on profitability (i.e., loss ratios), expenses, and return on equity. The basis we use to determine and analyze segments and to measure segment profit or loss have not changed from that reported in our Annual Report on Form 10-K for the year ended December 31, 2015. We have reconciled the amounts in the following table for the three-month periods ended March 31, 2016 and 2015 to the amounts reported in our unaudited Consolidated Financial Statements, adjusting for intersegment eliminations.
