Disclosure Text Block [Abstract] |
Note 1. Basis of Presentation | Note 1. Basis of Presentation AMERCO, a Nevada Corporation (“AMERCO”), has a fiscal year that ends on the 31st of March for each year that is referenced. Our insurance company subsidiaries have fiscal years that end on the 31st of December for each year that is referenced. They have been consolidated on that basis. Our insurance companies' financial reporting processes conform to calendar year reporting as required by state insurance departments. Management believes that consolidating their calendar year into our fiscal year financial statements does not materially affect the financial position or results of operations. We disclose any material events occurring during the intervening period. Consequently, all references to our insurance subsidiaries' years 2012, 2011 and 2010 correspond to fiscal 2013, 2012 and 2011 for AMERCO. Accounts denominated in non-U.S. currencies have been translated into U.S. dollars. Certain amounts reported in previous years have been reclassified to conform to the current presentation.
