Segment Reporting [Abstract] |
Consolidating Financial Information by Industry Segment | Note 21A. Consolidating Financial Information by Industry Segment AMERCO’s three reportable segments are: Moving and Storage, comprised of AMERCO, U-Haul, and Real Estate and the subsidiaries of U-Haul and Real Estate; Property and Casualty Insurance, comprised of Repwest and its subsidiaries and ARCOA; and Life Insurance, comprised of Oxford and its subsidiaries. Management tracks revenues separately, but does not report any separate measure of the profitability for rental vehicles, rentals of self-storage spaces and sales of products that are required to be classified as a separate operating segment and accordingly does not present these as separate reportable segments. Deferred income taxes, net are shown as liabilities on the consolidating statements. The information includes elimination entries necessary to consolidate AMERCO, the parent, with its subsidiaries. Investments in subsidiaries are accounted for by the parent using the equity method of accounting.
