1. Basis of Presentation U-Haul Holding Company and consolidated subsidiaries notes to condensed consolidated financial statements 1.Basis of Presentation U-Haul Holding Company, a Nevada corporation formerly known as AMERCO (“U-Haul Holding Company”), 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 30 th 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 presentation of financial position or results of operations. We disclose material events, if any, occurring during the intervening period. Consequently, all references to our insurance subsidiaries’ years 2022 and 2021 correspond to fiscal 2023 and 2022 for U-Haul Holding Company. Accounts denominated in non-U.S. currencies have been translated into U.S. dollars.   The condensed consolidated balance sheet as of December 31, 2022, and the related condensed consolidated statements of operations, comprehensive income (loss), stockholders’ equity for the third quarter and first nine months of fiscal 2023 and 2022 and cash flows for the first nine months of fiscal 2023 and 2022 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 (“Quarterly Report”) should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2022.

Earnings Per Share [Abstract]  
2. Earnings Per Share 2. Earnings per Share We calculate earnings per share using the two-class method in accordance with Accounting Standards Codification Topic 260, Earnings Per Share . The two-class method allocates the undistributed earnings available to common stockholders to the Company’s outstanding common stock, $ 0.25 par value (the “Voting Common Stock”) and the Series N Non-Voting Common Stock, $ 0.001 par value (the “Non-Voting Common Stock”) based on each share’s percentage of total weighted average shares outstanding. The Voting Common Stock and Non-Voting Common Stock are allocated 10 % and 90 %, respectively, of our undistributed earnings available to common stockholders. This represents earnings available to common stockholders less the dividends declared for both the Voting Common Stock and Non-Voting Common Stock. Our undistributed earnings per share is calculated by taking the undistributed earnings available to common stockholders and dividing this number by the weighted average shares outstanding for the respective stock. If there was a dividend declared for that period, the dividend per share is added to the undistributed earnings per share to calculate the basic and diluted earnings per share. The process is used for both Voting Common Stock and Non-Voting Common Stock. The calculation of basic and diluted earnings per share for the quarter and nine months ended December 31, 2022 and 2021 for our Voting Common Stock and Non-Voting Common Stock were as follows:     For the Quarter Ended     December 31,     2022 2021     (Unaudited)     (In thousands, except share and per share amounts)           Weighted average shares outstanding of Voting Common Stock   19,607,788   19,607,788 Total weighted average shares outstanding for Voting Common Stock and Non-Voting Common Stock   196,077,880   196,077,880 Percent of weighted average shares outstanding of Voting Common Stock   10%   10%           Net earnings available to common stockholders $ 199,244 $ 281,466 Voting Common Stock dividends declared   –   (9,804) Non-Voting Common Stock dividends declared   (7,059)   – Undistributed earnings available to common stockholders $ 192,185 $ 271,662 Undistributed earnings available to common stockholders allocated to Voting Common Stock $ 19,219 $ 27,166           Undistributed earnings per share of Voting Common Stock $ 0.98 $ 1.39 Dividends declared per share of Voting Common Stock $ – $ 0.50 Basic and diluted earnings per share of Voting Common Stock $ 0.98 $ 1.89                     Weighted average shares outstanding of Non-Voting Common Stock   176,470,092   176,470,092 Total weighted average shares outstanding for Voting Common Stock and Non-Voting Common Stock   196,077,880   196,077,880 Percent of weighted average shares outstanding of Non-Voting Common Stock   90%   90%           Net earnings available to common stockholders $ 199,244 $ 281,466 Voting Common Stock dividends declared   –   (9,804) Non-Voting Common Stock dividends declared   (7,059)   – Undistributed earnings available to common stockholders $ 192,185 $ 271,662 Undistributed earnings available to common stockholders allocated to Non-Voting Common Stock $ 172,967 $ 244,496           Undistributed earnings per share of Non-Voting Common Stock $ 0.98 $ 1.39 Dividends declared per share of Non-Voting Common Stock $ 0.04 $ – Basic and diluted earnings per share of Non-Voting Common Stock $ 1.02 $ 1.39         For the Nine Months Ended     December 31,     2022   2021     (Unaudited)     (In thousands, except share and per share amounts)           Weighted average shares outstanding of Voting Common Stock   19,607,788   19,607,788 Total weighted average shares outstanding for Voting Common Stock and Non-Voting Common Stock   196,077,880   196,077,880 Percent of weighted average shares outstanding of Voting Common Stock   10%   10%           Net earnings available to common stockholders $ 885,261 $ 1,036,539 Voting Common Stock dividends declared   (19,608)   (29,412) Non-Voting Common Stock dividends declared   (7,059)   – Undistributed earnings available to common stockholders $ 858,594 $ 1,007,127 Undistributed earnings available to common stockholders allocated to Voting Common Stock $ 85,859 $ 100,713           Undistributed earnings per share of Voting Common Stock $ 4.38 $ 5.14 Dividends declared per share of Voting Common Stock $ 1.00 $ 1.50 Basic and diluted earnings per share of Voting Common Stock $ 5.38 $ 6.64                     Weighted average shares outstanding of Non-Voting Common Stock   176,470,092   176,470,092 Total weighted average shares outstanding for Voting Common Stock and Non-Voting Common Stock   196,077,880   196,077,880 Percent of weighted average shares outstanding of Non-Voting Common Stock   90%   90%           Net earnings available to common stockholders $ 885,261 $ 1,036,539 Voting Common Stock dividends declared   (19,608)   (29,412) Non-Voting Common Stock dividends declared   (7,059)   – Undistributed earnings available to common stockholders $ 858,594 $ 1,007,127 Undistributed earnings available to common stockholders allocated to Non-Voting Common Stock $ 772,735 $ 906,414           Undistributed earnings per share of Non-Voting Common Stock $ 4.38 $ 5.14 Dividends declared per share of Non-Voting Common Stock $ 0.04 $ – Basic and diluted earnings per share of Non-Voting Common Stock $ 4.42 $ 5.14 Please see note 7, Stockholders’ Equity, of the Notes to Condensed Consolidated Financial Statements for more information on the Non-Voting Common Stock.

The gross realized gains on these sales totaled $ 1.1 million during the first nine months of fiscal 2023 and $ 9.5 million for the full year of fiscal 2022. The gross realized losses on these sales totaled $ 0.5 million during the first nine months of fiscal 2023 and $ 1.4 million for the full year of fiscal 2022. For available-for-sale debt securities in an unrealized loss position, we first assess whether the security is below investment grade. For securities that are below investment grade, we evaluate whether the decline in fair value has resulted from credit losses or other factors such as the interest rate environment. Declines in value due to credit quality are recognized as an allowance. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse market conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, cumulative default rates based on ratings are used to determine the potential cost of default, by year. The present value of these potential costs is then compared to the amortized cost of the security to determine the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through accumulated other comprehensive income, net of applicable taxes. If we intend to sell a security, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis, the security is written down to its fair value and the write down is charged against the allowance for credit losses, with any incremental impairment reported in earnings. Reversals of the allowance for credit losses are permitted and should not exceed the allowance amount initially recognized. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. There was a $ 2.2 million net impairment charge recorded in the first nine months ended December 31, 2022. The adjusted cost and estimated market value of available-for-sale investments by contractual maturity were as follows:     December 31, 2022   March 31, 2022     Cost Amortized   Market Value Estimated   Cost Amortized   Market Value Estimated     (Unaudited)         (In thousands) Due in one year or less $ 333,984 $ 333,803 $ 97,969 $ 99,432 Due after one year through five years   602,861   575,794   541,840   570,135 Due after five years through ten years   756,691   674,055   704,295   765,073 Due after ten years   919,765   746,989   995,904   1,056,295     2,613,301   2,330,641   2,340,008   2,490,935                   Mortgage-backed securities   375,819   332,887   324,029   330,157   $ 2,989,120 $ 2,663,528 $ 2,664,037 $ 2,821,092   As of December 31, 2022 and March 31, 2022, our common stock and non-redeemable preferred stock that are included in Investments, fixed maturities and marketable equities on our balance sheet are stated in the table below.

These loans require monthly or quarterly principal and interest payments, with the unpaid loan balance and accrued and unpaid interest due at maturity. These loans are secured by various properties owned by the borrowers. The interest rates, per the provisions of $ 208.5 million of these loans, are the applicable Secured Overnight Funding Rate (“SOFR”) plus the applicable margins and a credit spread adjustment of 0.10 %. As of December 31, 2022, the applicable SOFR was between 3.79 % and 4.12 % and applicable margin was between 0.65 % and 1.38 %, the sum of which, including the credit spread, was between 4.54 % and 5.60 %. The remaining $ 84.2 million of these loans was fixed with an interest rate of 4.29 %. The default provisions of these real estate loans include non-payment of principal or interest and other standard reporting and change-in-control covenants. Senior Mortgages Various subsidiaries of Real Estate and U-Haul are borrowers under certain senior mortgages. The senior mortgages require monthly principal and interest payments. The senior mortgages are secured by certain properties owned by the borrowers. The fixed interest rates, per the provisions of the senior mortgages, range between 2.70% and 5.50%. The weighted average interest rate of these loans as of December 31, 2022 was 4.09%.  Certain senior mortgages have an anticipated repayment date and a maturity date. If these senior mortgages are not repaid by the anticipated repayment date, the interest rate on these mortgages would increase from the current fixed rate. We are using the anticipated repayment date for our maturity schedule. Real Estate and U-Haul have provided limited guarantees of the senior mortgages. The default provisions of the senior mortgages include non-payment of principal or interest and other standard reporting and change-in-control covenants. There are limited restrictions regarding our use of the funds. Real Estate Loan (Revolving Credit) U-Haul Holding Company is a borrower under a real estate loan. As of December 31, 2022, the maximum credit commitment is $ 465.0 million. As of December 31, 2022, the full capacity was available to borrow. This loan agreement provides for revolving loans, subject to the terms of the loan agreement. This loan requires monthly interest payments with the unpaid loan balance and accrued and unpaid interest due at maturity. The default provisions of the loan include non-payment of principal or interest and other standard reporting and change-in-control covenants. There is a 0.30 % fee charged for unused capacity. This loan was amended in October 2022 and the maximum credit limit was increased from $ 150 million to $ 465 million, the maturity extended to October 2027 and LIBOR based rates were replaced with SOFR based rates. Fleet Loans Rental Truck Amortizing Loans The amortizing loans require monthly principal and interest payments, with the unpaid loan balance and accrued and unpaid interest due at maturity. These loans were used to purchase new trucks. The interest rates, per the provision of the loan agreements, are carried at fixed rates ranging between 1.61 % and 5.68 %.   All of our rental truck amortizing loans are collateralized by the rental equipment purchased.   The majority of these loans are funded at 70%, but some may be funded at 100%. U-Haul Holding Company, and in some cases U-Haul, is guarantor of these loans. The default provisions of these loans include non-payment of principal or interest and other standard reporting and change-in-control covenants. Rental Truck Revolvers Various subsidiaries of U-Haul entered into three revolving fleet loans with an aggregate borrowing capacity of $ 615.0 million. The aggregate outstanding balance for these revolvers as of December 31, 2022 was $ 615.0 million. The interest rates, per the provision of the loan agreements, are SOFR plus the applicable margin and a credit spread adjustment of 0.10 %. As of December 31, 2022,   SOFR was between 3.70 % and 4.12 % and the margin was between 1.15 % and 1.25 %, the sum of which, including the credit spread, was between 4.95 % and 5.44 %. Of the $ 615.0 million outstanding, $ 100.0 million was fixed with an interest rate of 2.36 %. Only interest is paid on the loans until the last nine months of the respective loan terms when principal becomes due monthly. Finance Leases The Finance Lease balance represents our sale-leaseback transactions of rental equipment. The agreements are generally seven (7) year terms with interest rates ranging from 2.16 % to 5.04 %.   All of our finance leases are collateralized by our rental fleet. The net book value of the corresponding rental equipment was $ 504.6 million and $ 620.8 million as of December 31, 2022 and March 31, 2022, respectively. There were no new financing leases, as assessed under the new leasing guidance, entered into during the first nine months of fiscal 2023. Finance Liabilities Finance liabilities represent our rental equipment financing transactions, and we assess if these sale-leaseback transactions qualify as a sale at initiation by determining if a transfer of ownership occurs.  We have determined that our equipment sale-leasebacks do not qualify as a sale, as the buyer-lessors do not obtain control of the assets in our ongoing sale-leaseback arrangements. As a result, these sale-leasebacks are accounted for as a financial liability and the leased assets are capitalized at cost.   Our finance liabilities have an average term of seven (7) years and interest rates ranging from 1.60% to 5.98%. These finance liabilities are collateralized by the related assets of our rental fleet. The net book value of the corresponding rental equipment was $1,399.5 million and $1,068.3 million as of December 31, 2022 and March 31, 2022, respectively. Private Placements In September 2021, U-Haul Holding Company entered into a note purchase agreement to issue $ 600.0 million of fixed rate senior unsecured notes in a private placement offering.   These notes consist of four tranches each totaling $ 150.0 million and funded in September 2021.   The fixed interest rates range between 2.43 % and 2.78 % with maturities between 2029 and 2033 .   Interest is payable semiannually.   In December 2021, U-Haul Holding Company entered into a note purchase agreement to issue $ 600.0 million of fixed rate senior unsecured notes in a private placement offering. These notes consist of three tranches each totaling $ 100.0 million and two tranches each totaling $ 150.0 million.   The fixed interest rates range between 2.55 % and 2.88 % with maturities between 2030 and 2035 .   Interest is payable semiannually.   Other Obligations In February 2011, U-Haul Holding Company and U.S. Bank Trust Company, NA, as successor in interest to U.S. Bank National Association (the “Trustee”), entered into the U-Haul Investors Club ® Indenture.   U-Haul Holding Company and the Trustee entered into this indenture to provide for the issuance of notes by us directly to investors over our proprietary website, uhaulinvestorsclub.com (“U-Notes ® ”). The U-Notes ® are secured by various types of collateral, including, but not limited to, certain rental equipment and real estate.   U-Notes ® are issued in smaller series that vary as to principal amount, interest rate and maturity.   U-Notes ® are obligations of the Company and secured by the associated collateral; they are not guaranteed by any of the Company’s affiliates or subsidiaries. As of December 31, 2022, the aggregate outstanding principal balance of the U-Notes ® issued was $ 79.2 million, of which $ 1.8 million is held by our insurance subsidiaries and eliminated in consolidation. Interest rates range between 1.50 % and 8.00 % and maturity dates range between 2023 and 2049 . Oxford is a member of the Federal Home Loan Bank (“FHLB”) and, as such, the FHLB has made deposits with Oxford.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
5. Derivatives 5. Derivatives We manage exposure to changes in market interest rates. Our use of derivative instruments is limited to highly effective interest rate swaps to hedge the risk of changes in cash flows (future interest payments) attributable to changes in SOFR swap rates with the designated benchmark interest rate being hedged on certain of our SOFR indexed variable rate debt.   The interest rate swaps effectively fix our interest payments on certain SOFR indexed variable rate debt through July 2032. We monitor our positions and the credit ratings of our counterparties and do not currently anticipate non-performance by the counterparties. Interest rate swap agreements are not entered into for trading purposes.   These fair values are determined using pricing valuation models which include broker quotes for which significant inputs are observable. They include adjustments for counterparty credit quality and other deal-specific factors, where appropriate and are classified as Level 2 in the fair value hierarchy. The derivative fair values reflected in prepaid expense and accounts payable and accrued expenses in the condensed consolidated balance sheet were as follows:     Derivatives Fair Values as of     December 31, 2022   March 31, 2022     (Unaudited)         (In thousands) Interest rate contracts designated as cash flow hedging instruments:         Assets $ 8,206 $ – Liabilities $ – $ 587 Notional amount $ 208,467 $ 235,000       The Effect of Interest Rate Contracts on the Statements of Operations for the Quarters Ended         December 31, 2022   December 31, 2021     (Unaudited)     (In thousands) (Gain) loss recognized in AOCI on interest rate contracts $ 302 $ (1,242) (Gain) loss reclassified from AOCI into income $ 455 $ (1,007)   Gains or losses recognized in income on interest rate derivatives are recorded as interest expense in the condensed consolidated statements of operations. During the first nine months of fiscal 2023 and 2022, we recognized an increase in the fair value of our cash flow hedges of $6.5 million and $0.1 million, respectively, net of taxes. During the first nine months of fiscal 2023 and 2022, we reclassified $0.1 million and $2.3 million, respectively, from accumulated other comprehensive income (loss) (“AOCI”) to interest expense, net of tax. As of December 31, 2022, we expect to reclassify $2.3 million of net gains on interest rate contracts from AOCI to earnings as interest expense over the next twelve months. We use derivatives to hedge our equity market exposure to indexed annuity products sold by our Life Insurance company. These contracts earn a return for the contractholder based on the change in the value of the S&P 500 index between annual index point dates. We buy and sell listed equity and index call options and call option spreads. The credit risk is with the party in which the options are written. The net option price is paid up front and there are no additional cash requirements or additional contingent liabilities. These contracts are held at fair value on our balance sheet. These derivative instruments are included in Investments, other, on the condensed consolidated balance sheets. Net (gains) losses recognized in net investment and interest income for the third quarters of fiscal 2023 and 2022 were $ 1.4 million and $ 0.1 million, respectively and $ 9.2 million and ($ 1.8 ) million for the first nine months of fiscal 2023 and fiscal 2022, respectively. The fair values of these call options are determined based on quoted market prices from the relevant exchange and are classified as Level 1 in the fair value hierarchy.       Derivatives Fair Values as of     December 31, 2022   March 31, 2022     (Unaudited)         (In thousands) Equity market contracts as hedging instruments         Assets $ 2,181 $ 7,474 Liabilities $ – $ – Notional amount $ 456,419 $ 416,739 Although the call options are employed to be effective hedges against our policyholder obligations from an economic standpoint, they do not meet the requirements for hedge accounting under generally accepted accounting principles (“GAAP”). Accordingly, the changes in fair value of the call options are recognized each reporting date as a component of net investment and interest income. The change in fair value of the call options include the gains or losses recognized at the expiration of the option term and the changes in fair value for open contracts.

9. Contingencies 9. Contingencies Cybersecurity Incident On September 9, 2022, we announced that the Company was made aware of a data security incident involving U-Hauls information technology network. U-Haul detected a compromise of two unique passwords used to access U-Haul customers‘ information. U-Haul took immediate steps to contain the incident and promptly enhanced its security measures to prevent any further unauthorized access. U-Haul retained cybersecurity experts and incident response counsel to investigate the incident and implement additional security safeguards. The investigation determined that between November 5, 2021 and April 8, 2022, the threat actor accessed customer contracts containing customers’ names, dates of birth, and driver’s license or state identification numbers. None of U-Haul’s financial, payment processing or email systems were involved. U-Haul has notified impacted customers and relevant governmental authorities. Several class action lawsuits related to the incident have been filed against U-Haul. The lawsuits have been consolidated into one action in the U.S. District Court for the District of Arizona and will be vigorously defended by the Company, however the outcome of such lawsuits cannot be predicted or guaranteed with any certainty. Environmental Compliance with environmental requirements of federal, state and local governments may significantly affect Real Estate’s business operations. Among other things, these requirements regulate the discharge of materials into the air, land and water and govern the use and disposal of hazardous substances. Real Estate is aware of issues regarding hazardous substances on some of its properties. Real Estate regularly makes capital and operating expenditures to stay in compliance with environmental laws and has put in place a remedial plan at each site where it believes such a plan is necessary. Based upon the information currently available to Real Estate, compliance with the environmental laws and its share of the costs of investigation and cleanup of known hazardous waste sites are not expected to result in a material adverse effect on the Company’s financial position or results of operations. Other We are named as a defendant in various other litigation and claims arising out of the normal course of business, including various class actions related to the Company’s cybersecurity incident described above. In management’s opinion, none of these other matters will have a material effect on our financial position and results of operations.

Accordingly, all such related party transactions are submitted to the Audit Committee for ongoing review and oversight. Our internal processes are designed to ensure that our legal, accounting and finance departments identify and monitor potential related party transactions that may require disclosure and Audit Committee oversight. U-Haul Holding Company has engaged in related party transactions and has continuing related party interests with certain major stockholders, directors and officers of the consolidated group as disclosed below. SAC Holding Corporation and SAC Holding II Corporation (collectively “SAC Holdings”) were established in order to acquire and develop self-storage properties. These properties are being managed by us pursuant to management agreements. SAC Holdings, Four SAC Self-Storage Corporation, Five SAC Self-Storage Corporation, Galaxy Investments, L.P. and 2015 SAC Self-Storage, LLC are substantially controlled by Blackwater Investments, Inc. (“Blackwater”). Blackwater is wholly owned by Willow Grove Holdings LP, which is owned by Mark V. Shoen (a significant stockholder), and various trusts associated with Edward J. Shoen (our Chairman of the Board, President and a significant stockholder) and Mark V. Shoen.

(“Mercury”), pursuant to a standard form of management agreement, under which we receive a management fee of between 4% and 10% of the gross receipts plus reimbursement for certain expenses. We received management fees, exclusive of reimbursed expenses, of $24.9 million and $27.1 million from the above-mentioned entities during the first nine months of fiscal 2023 and 2022, respectively.  The decrease in management fees received in the first nine months of fiscal 2023 compared with the first nine months of fiscal 2022 was due to a timing difference of the incentive fee of $4.0 million being paid in March of fiscal 2022. This management fee is consistent with the fee received for other properties we previously managed for third parties. Mark V. Shoen controls the general partner of Mercury. The limited partner interests of Mercury are owned indirectly by James P. Shoen (is the brother of Edward J. Shoen and Mark V. Shoen) and various trusts benefitting Edward J. Shoen and James P. Shoen or their descendants.  Mercury holds the option to purchase a portfolio of properties currently leased by Mercury and a U-Haul subsidiary, which option is exercisable in 2024.

As of December 31, 2022, subsidiaries of Blackwater acted as independent dealers. The financial and other terms of the dealership contracts are substantially identical to the terms of those with our other independent dealers whereby commissions are paid by us based upon equipment rental revenues. These agreements with subsidiaries of Blackwater, excluding Dealer Agreements, provided revenues of $ 22.7 million and $ 21.6 million, expenses of $ 1.8 million and $ 1.8 million and cash flows of $ 21.0 million and $ 19.8 million, respectively during the first nine months of fiscal 2023 and 2022.

Fair Value Disclosures [Abstract]  
14. Fair Value Measurements 14. Fair Value Measurements Certain assets and liabilities are recorded at fair value on the condensed consolidated balance sheets and are measured and classified based upon a three-tiered approach to valuation. Financial assets and liabilities are recorded at fair value and are classified and disclosed in one of the following three categories: Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;   Level 2 – Quoted prices for identical or similar financial instruments in markets that are not considered to be active, or similar financial instruments for which all significant inputs are observable, either directly or indirectly, or inputs other than quoted prices that are observable, or inputs that are derived principally from or corroborated by observable market data through correlation or other means; and Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and are unobservable. These reflect management’s assumptions about the assumptions a market participant would use in pricing the asset or liability. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Fair values of cash equivalents approximate carrying value due to the short period of time to maturity. Fair values of short-term investments, investments available-for-sale, long-term investments, mortgage loans and notes on real estate, and interest rate swap contracts are based on quoted market prices, dealer quotes or discounted cash flows. Fair values of trade receivables approximate their recorded value. Our financial instruments that are exposed to concentrations of credit risk consist primarily of temporary cash investments, trade receivables, reinsurance recoverables and notes receivable. Limited credit risk exists on trade receivables due to the diversity of our customer base and their dispersion across broad geographic markets. We place our temporary cash investments with financial institutions and limit the amount of credit exposure to any one financial institution. We have mortgage receivables, which potentially expose us to credit risk. The portfolio of notes is principally collateralized by self-storage facilities and commercial properties. We have not experienced any material losses related to the notes from individual or groups of notes in any particular industry or geographic area. The estimated fair values were determined using the discounted cash flow method and using interest rates currently offered for similar loans to borrowers with similar credit ratings. Other investments, including short-term investments, are substantially current or bear reasonable interest rates. As a result, the carrying values of these financial instruments approximate fair value. The carrying values and estimated fair values for the financial instruments stated above and their placement in the fair value hierarchy are as follows:     Fair Value Hierarchy     Carrying               Total Estimated As of December 31, 2022   Value   Level 1   Level 2   Level 3   Fair Value     (Unaudited) Assets   (In thousands) Reinsurance recoverables and trade receivables, net $ 208,182 $ – $ – $ 208,182 $ 208,182 Mortgage loans, net   414,886   –   –   414,886   393,980 Other investments   103,569   –   –   103,569   103,569 Total $ 726,637 $ – $ – $ 726,637 $ 705,731                                             Liabilities                     Notes, loans and finance leases payable $ 6,236,822 $ – $ 6,236,822 $ – $ 5,813,962 Total $ 6,236,822 $ – $ 6,236,822 $ – $ 5,813,962           Fair Value Hierarchy     Carrying               Total Estimated As of March 31, 2022   Value   Level 1   Level 2   Level 3   Fair Value     (In thousands) Assets                     Reinsurance recoverables and trade receivables, net $ 229,343 $ – $ – $ 229,343 $ 229,343 Mortgage loans, net   423,163   –   –   423,163   450,347 Other investments   120,592   –   –   120,592   120,592 Total $ 773,098 $ – $ – $ 773,098 $ 800,282                                             Liabilities                     Notes, loans and finance leases payable $ 6,059,713 $ – $ 6,059,713 $ – $ 5,875,781 Total $ 6,059,713 $ – $ 6,059,713 $ – $ 5,875,781 The following tables represent the financial assets and liabilities on the condensed consolidated balance sheets as of December 31, 2022 and March 31, 2022, that are measured at fair value on a recurring basis and the level within the fair value hierarchy.   As of December 31, 2022   Total   Level 1   Level 2   Level 3     (Unaudited) Assets   (In thousands) Short-term investments $ 2,193,606 $ 2,193,606 $ – $ – Fixed maturities - available for sale   2,663,528   249,161   2,414,275   92 Preferred stock   22,054   22,054   –   – Common stock   37,619   37,619   –   – Derivatives   10,388   2,182   8,206   – Total $ 4,927,195 $ 2,504,622 $ 2,422,481 $ 92                                     Liabilities                 Derivatives $ – $ – $ – $ – Total $ – $ – $ – $ –   As of March 31, 2022   Total   Level 1   Level 2   Level 3     (In thousands) Assets                 Short-term investments $ 2,482,154 $ 2,482,154 $ – $ – Fixed maturities - available for sale   2,821,092   26,914   2,794,086   92 Preferred stock   26,095   26,095   –   – Common stock   46,212   46,212   –   – Derivatives   7,474   7,474   –   – Total $ 5,383,027 $ 2,588,849 $ 2,794,086 $ 92                                     Liabilities                 Derivatives $ 587 $ – $ 587 $ – Total $ 587 $ – $ 587 $ –   The fair value measurements for our assets using significant unobservable inputs (Level 3) were $ 0.1 million for both December 31, 2022 and March 31, 2022.

Revenue From Contract With Customer [Abstract]  
Revenue Recognition 15. Revenue Recognition Revenue Recognized in Accordance with Topic 606 ASC Topic 606, Revenue from Contracts with Customers (Topic 606), outlines a five-step model for entities to use in accounting for revenue arising from contracts with customers. The standard applies to all contracts with customers except for leases, insurance contracts, financial instruments, certain nonmonetary exchanges and certain guarantees. The standard also requires disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. We enter into contracts that may include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of amounts collected from customers for taxes, such as sales tax, and remitted to the applicable taxing authorities. We account for a contract under Topic 606 when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. For contracts scoped into this standard, revenue is recognized when (or as) the performance obligations are satisfied by means of transferring goods or services to the customer as applicable to each revenue stream as discussed below. There were no material contract assets or liabilities as of December 31, 2022 and March 31, 2022. Sales of self-moving and self-storage related products are recognized at the time that title passes and the customer accepts delivery. The performance obligations identified for this portfolio of contracts include moving and storage product sales, installation services and/or propane sales. Each of these performance obligations has an observable stand-alone selling price. We concluded that the performance obligations identified are satisfied at a point in time. The basis for this conclusion is that the customer does not receive the product/propane or benefit from the installation services until the related performance obligation is satisfied. These products/services being provided have an alternative use as they are not customized and can be sold/provided to any customer. In addition, we only have the right to receive payment once the products have been transferred to the customer or the installation services have been completed. Although product sales have a right of return policy, our estimated obligation for future product returns is not material to the financial statements at this time. Property management fees are recognized over the period that agreed-upon services are provided. The performance obligation for this portfolio of contracts is property management services, which represents a series of distinct days of service, each of which is comprised of activities that may vary from day to day. However, those tasks are activities to fulfill the property management services and are not separate promises in the contract. We determined that each increment of the promised service is distinct. This is because the customer can benefit from each increment of service on its own and each increment of service is separately identifiable because no day of service significantly modifies or customizes another and no day of service significantly affects either the entity’s ability to fulfill another day of service or the benefit to the customer of another day of service. As such, we concluded that the performance obligation is satisfied over time. Additionally, in certain contracts the Company has the ability to earn an incentive fee based on operational results. We measure and recognize the progress toward completion of the performance obligation on a quarterly basis using the most likely amount method to determine an accrual for the incentive fee portion of the compensation received in exchange for the property management service. The variable consideration recognized is subject to constraints due to a range of possible consideration amounts based on actual operational results. The amount accrued in the third quarter of fiscal 2023 did not have a material effect on our financial statements. Other revenue consists of numerous services or rentals, of which U-Box contracts and service fees from Moving Help are the main components. The performance obligations identified for U-Box contracts are fees for rental, storage and shipping of U-Box containers to a specified location, each of which are distinct. A contract may be partially within the scope of Topic 606 and partially within the scope of other topics. The rental and storage obligations in U-Box contracts meet the definition of a lease in Topic 842, while the shipping obligation represents a contract with a customer accounted for under Topic 606. Therefore, we allocate the total transaction price between the performance obligations of storage fees and rental fees and the shipping fees on a standalone selling price basis. U-Box shipping fees are collected once the shipment is in transit. Shipping fees in U-Box contracts are set at the initiation of the contract based on the shipping origin and destination, and the performance obligation is satisfied over time. U-Box shipping contracts span over a relatively short period of time, and the majority of these contracts begin and end within the same fiscal year. Moving Help services fees are recognized in accordance with Topic 606. Moving Help services are generated as we provide a neutral venue for the connection between the service provider and the customer for agreed upon services. We do not control the specified services provided by the service provider before that service is transferred to the customer. Revenue Recognized in Accordance with Topic 842 The Company’s self-moving rental revenues meet the definition of a lease pursuant to the guidance in Topic 842 because those substitution rights do not provide an economic benefit to the Company that would exceed the cost of exercising the right.   Please see Note 8, Leases, of the Notes to the Condensed Consolidated Financial Statements. Self-moving rentals are recognized over the contract period that trucks and moving equipment are rented. We offer two types of self-moving rental contracts, one-way rentals and in-town rentals, which have varying payment terms. Customer payment is received at the initiation of the contract for one-way rentals which covers an allowable limit for equipment usage. An estimated fee in the form of a deposit is received at the initiation of the contract for in-town rentals, and final payment is received upon the return of the equipment based on actual fees incurred. The contract price is estimated at the initiation of the contract, as there is variable consideration associated with ratable fees incurred based on the number of days the equipment is rented and the number of miles driven. Variable consideration is estimated using the most likely amount method which is based on the intended use of the rental equipment by the customer at the initiation of the contract. Historically, the variability in estimated transaction pricing compared to actual is not significant due to the relatively short duration of rental contracts. Each performance obligation has an observable stand-alone selling price. The input method of passage of time is appropriate as there is a direct relationship between our inputs and the transfer of benefit to the customer over the life of the contract. Self-moving rental contracts span a relatively short period of time, and the majority of these contracts began and ended within the same fiscal year. Self-storage revenues are recognized as earned over the contract period based upon the number of paid storage contract days. We lease portions of our operating properties to tenants under agreements that are classified as operating leases. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term. Generally, under the terms of our leases, the majority of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. The following table summarizes the minimum lease payments due from our customers and operating property tenants on leases for the next five years and thereafter:     Year Ending December 31,     2023   2024   2025   2026   2027   Thereafter     (Unaudited)     (In thousands)                           Self-moving equipment rentals $ 5,724 $ – $ – $ – $ – $ – Property lease revenues   20,136   12,290   9,403   7,634   5,095   39,749 Total $ 25,860 $ 12,290 $ 9,403 $ 7,634 $ 5,095 $ 39,749   The amounts above do not reflect future rental revenue from the renewal or replacement of existing leases. Revenue Recognized in Accordance with Other Topics Traditional life and Medicare supplement insurance premiums are recognized as revenue over the premium-paying periods of the contracts when due from the policyholders. For products where premiums are due over a significantly shorter duration than the period over which benefits are provided, such as our single premium whole life product, premiums are recognized when received and excess profits are deferred and recognized in relation to the insurance in force. Property and casualty insurance premiums are recognized as revenue over the policy periods. Interest and investment income are recognized as earned. Net investment and interest income has multiple components. Interest income from bonds and mortgage notes are recognized when earned. Dividends on common and preferred stocks are recognized on the ex-dividend dates. Realized gains and losses on the sale or exchange of investments are recognized at the trade date. In the following tables, revenue is disaggregated by timing of revenue recognition:     Quarter Ended December 31,     2022   2021     (Unaudited)     (In thousands)           Revenues recognized over time: $   69,797 $   73,785 Revenues recognized at a point in time:   92,698   90,763 Total revenues recognized under ASC 606   162,495   164,548           Revenues recognized under ASC 842   1,110,247   1,154,751 Revenues recognized under ASC 944   50,300   53,853 Revenues recognized under ASC 320   52,294   31,184 Total revenues $   1,375,336 $   1,404,336       Nine Months Ended December 31,     2022   2021     (Unaudited)     (In thousands)           Revenues recognized over time: $   300,082 $   261,638 Revenues recognized at a point in time:   338,019   322,405 Total revenues recognized under ASC 606   638,101   584,043           Revenues recognized under ASC 842   3,772,203   3,701,695 Revenues recognized under ASC 944   149,360   152,745 Revenues recognized under ASC 320   116,376   102,963 Total revenues $   4,676,040 $   4,541,446 In the above tables, the revenues recognized over time include property management fees, the shipping fees associated with U-Box container rentals and a portion of other revenues. Revenues recognized at a point in time include self-moving equipment rentals, self-moving and self-storage products and service sales and a portion of other revenues . We recognized liabilities resulting from contracts with customers for self-moving equipment rentals, self-storage revenues, U-Box revenues and tenant revenues, in which the length of the contract goes beyond the reported period end, although rental periods of the equipment, storage and U-Box contract are generally short-term in nature. The timing of revenue recognition results in liabilities that are reflected in deferred income on the balance sheet.

Allowance For Credit Loss [Abstract]  
Allowance For Credit Losses [Text Block] 16. Allowance for Credit Losses Trade Receivables Moving and Storage has two ( 2 ) primary components of trade receivables, receivables from corporate customers and credit card receivables from customer sales and rental of equipment.   For credit card receivables, the Company uses a trailing 13 months average historical chargeback percentage of total credit card receivables to estimate a credit loss reserve. The Company rents equipment to corporate customers in which payment terms are 30 days. The Company performs ongoing credit evaluations of its customers and assesses each customer’s credit worthiness. In addition, the Company monitors collections and payments from its customers and maintains an allowance based upon applying an expected credit loss rate to receivables based on the historical loss rate from similar high risk customers adjusted for current conditions, including any specific customer collection issues identified, and forecasts of economic conditions. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. Management believes that the historical loss information it has compiled is a reasonable base on which to determine expected credit losses for trade receivables because the composition of trade receivables as of that date is consistent with that used in developing the historical credit loss percentages (i.e., the similar risk characteristics of its customers and its lending practices have not changed significantly over time).   To adjust the historical loss rates to reflect the effects of these differences in current conditions and forecasted changes, management assigns a rating to each corporate customer which varies depending on the assessment of risk. Management estimated the loss rate at approximately 4 % and 6 % as of December 31, 2022 and March 31, 2022, respectively. Management developed this estimate based on its knowledge of past experience for which there were similar improvements in the economy. As a result, management applied the applicable credit loss rates to determine the expected credit loss estimate for each aging category. Accordingly, the allowance for expected credit losses as of December 31, 2022, was $ 4.0 million. Accrued Interest Receivable Accrued interest receivables on available for sale securities totaled $ 29.6 million as of September 30, 2022 and are excluded from the estimate of credit losses. As outlined in subtopic 326-20-30-5A, we have elected not to measure an allowance on accrued interest receivables as our practice is to write off the uncollectible balance in a timely manner. Furthermore, we have elected to write off accrued interest receivables by reversing interest income (in accordance with subtopic 326-20-35-8A). Mortgage loans, net Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at amortized cost.   Modeling for the Company‘s mortgage loans is based on inputs most highly correlated to defaults, including loan-to-value, occupancy, and payment history.   Historical credit loss experience provides additional support for the estimation of expected credit losses. In assessing the credit losses, the portfolio is reviewed on a collective basis, using loan-specific cash flows to determine the fair value of the collateral in the event of default.   Adjustments to this analysis are made to assess loans with a loan-to-value of 65% or greater.   These loans are evaluated on an individual basis and loan specific risk characteristics such as occupancy levels, expense, income growth and other relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts. When management determines that credit losses are expected to occur, an allowance for expected credit losses based on the fair value of the collateral is recorded. Reinsurance recoverables Reinsurance recoverables on paid and unpaid benefits was less than 1% of the total assets as of September 30, 2022 which is immaterial based on historical loss experience and high credit rating of the reinsurers. Premium receivables Premium receivables   were $ 4.0 million as of September 30, 2022, in which the credit loss allowance is immaterial based on our ability to cancel the policy if the policyholder doesn't pay premiums. The following details the changes in the Company’s reserve allowance for credit losses for trade receivables, fixed maturities and investments, other:       Allowance for Credit Losses     Trade Receivables   Investments, Fixed Maturities   Investments, other   Total     (Unaudited)     (In thousands) Balance as of March 31, 2021 $ 4,421 $ 1,320 $ 501 $ 6,242 Provision for (reversal of) credit losses   4,228   (1,260)   –   2,968 Write-offs against allowance   –   –   –   – Recoveries   –   –   –   – Balance as of March 31, 2022 $ 8,649 $ 60 $ 501 $ 9,210 Provision for (reversal of) credit losses   (4,630)   2,183   5   (2,442) Write-offs against allowance   –   –   –   – Recoveries   –   –   –   – Balance as of December 31, 2022 $ 4,019   2,243 $ 506 $ 6,768

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]  
New Accounting Pronouncements And Changes In Accounting Principles [Text Block] 17.   Accounting Pronouncements Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts (“ASU 2018-12”). The amendments in this update require insurance companies to annually review and update the assumptions used for measuring the liability under long-duration contracts, such as life insurance, disability income, and annuities. The amendment prescribes standardized liability discount rate, consistency in measurement of market risk benefits, simplified amortization of deferred acquisition costs and enhanced disclosures. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2020. In November 2020, FASB issued ASU 2020-11, Financial Services – Insurance (Topic 944) , which deferred the effective date of ASU 2018-12 to years beginning after December 15, 2022. We are currently in the process of evaluating the impact of the adoption of ASU 2018-12 on our financial statements; however, the adoption of ASU 2018-12 will impact the statements of operations because the effect of any update to the assumptions we used at the inception of the contracts will be recorded in net income. From time to time, new accounting pronouncements are issued by the FASB or the SEC that are adopted by us as of the specified effective date. Unless otherwise discussed, these ASUs entail technical corrections to existing guidance or affect guidance related to specialized industries or entities and therefore will have minimal, if any, impact on our financial position or results of operations upon adoption.

Financing Receivable Allowance For Credit Loss Additional Information [Abstract]    
Modeling of mortgage loans Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoff, are reported at amortized cost.   Modeling for the Company‘s mortgage loans is based on inputs most highly correlated to defaults, including loan-to-value, occupancy, and payment history.   Historical credit loss experience provides additional support for the estimation of expected credit losses. In assessing the credit losses, the portfolio is reviewed on a collective basis, using loan-specific cash flows to determine the fair value of the collateral in the event of default.   Adjustments to this analysis are made to assess loans with a loan-to-value of 65% or greater.
