Segment Reporting [Abstract] |
Segment Information | The Company conducts and manages its business through four segments. The three operating segments, representing the major lines of insurance business, are: Property and Casualty, primarily personal lines automobile and property insurance products; Retirement, primarily tax-qualified fixed and variable annuities; and Life, life insurance. The Company does not allocate the impact of corporate-level transactions to these operating segments, consistent with the basis for management's evaluation of the results of those segments, but classifies those items in the fourth segment, Corporate and Other. In addition to ongoing transactions such as corporate debt service, net investment gains (losses) and certain public company expenses, such items also have included corporate debt retirement costs, when applicable. The accounting policies of the segments are the same as those described in Note 1 — Summary of Significant Accounting Policies. The Company accounts for intersegment transactions, primarily the allocation of operating and agency costs from Corporate and Other to Property and Casualty, Retirement and Life, on a direct cost basis. Summarized financial information for these segments is as follows:
