1. Basis of Presentation | 1. Basis of Presentation AMERCO, a Nevada corporation ("AMERCO"), has a third fiscal quarter that ends on the 31st of December for each year that is referenced. Our insurance company subsidiaries have a third quarter that ends on the 30th of September 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. The Company discloses any material events occurring during the intervening period. Consequently, all references to our insurance subsidiaries' years 2011 and 2010 correspond to fiscal 2012 and 2011 for AMERCO. During the Property and Casualty segment's fourth quarter (October 2011 to December 2011) an adjustment was made to strengthen excess workers' compensation reserves. Due to the materiality of this adjustment and its timing in relation to AMERCO's third quarter reporting, the adjustment was recorded into the Property and Casualty third quarter fiscal 2012 results as presented herein. 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. The condensed consolidated balance sheet as of December 31, 2011 and the related condensed consolidated statements of operations and comprehensive income for the third quarter and the first nine months and the cash flows for the first nine months ended fiscal 2012 and 2011 are unaudited. In our opinion, all adjustments necessary for the fair presentation of such condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. Interim results are not necessarily indicative of results for a full year. The information in this Quarterly Report on Form 10-Q should be read in conjunction with Management's Discussion and Analysis of Financial Condition and Results of Operations and financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2011. Intercompany accounts and transactions have been eliminated. Description of Legal Entities AMERCO is the holding company for: U-Haul International, Inc.
