Revenue From Contract With Customer [Abstract]
Revenue Recognition	Note 23.   Revenue Recognition Revenue Recognized in Accordance with Topic 606 On April 1, 2018, we adopted ASC Topic 606, Revenue from Contracts with Customers (Topic 606) , on a modified retrospective basis. The standard 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 expanded disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. Due to insignificant changes in our revenue recognition pattern for applicable revenue streams as a result of the updated guidance, there was no cumulative effect recorded.   Additionally, we elected to use the practical expedient for contracts that begin and end within the same reporting period in applying the updated guidance to our applicable revenue streams. The adoption of the standard did not have a material effect on our Consolidated Balance Sheets, Consolidated Statements of Operations, or Consolidated Statements of Cash Flows. 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 March 31, 2020 and March 31, 2019. 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 under Topic 606, which is consistent with the timing of our revenue recognition under legacy guidance. 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 in accordance with paragraph 606-10-25-19. 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 under Topic 606, which is consistent with the timing of our revenue recognition under legacy guidance for the Management Fee component of the compensation received in exchange for the service. Additionally, in certain contracts the Company has the ability to earn an incentive fee based on operational results. Historically, these fees have been recognized once fully determinable. Under Topic 606, 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 fourth quarter of fiscal 2020 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 F- 61       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 under Topic 606, which is consistent with the timing of our revenue recognition under legacy guidance. 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 withTopic 842/840 The Company’s self-moving rental revenues meet the definition of a lease pursuant to the guidance in ASU 2016-02, Leases (Topic 842) because those substitution rights do not provide an economic benefit to the Company that would exceed the cost of exercising the right.   Therefore, upon adoption of Topic 842 on April 1, 2019, self-rental contracts are being accounted for as leases. We combined all lease and non-lease components of lease contracts for which the timing and pattern of transfer are the same and the lease component meets the classification of an operating lease, and account for them in accordance with Topic 842. The revenue streams accounted for in accordance with Topic 842 are recognized evenly over the period of rental. We do not expect this change to result in a change in the timing and pattern of recognition of the related revenues due to the short-term nature of the self-moving rental contracts. Please see Note 18, Leases, of the Notes to Condensed Consolidated Financial Statements. 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 Ended March 31,     2021   2022   2023   2024   2025   Thereafter           (In thousands)                           Self-moving equipment rentals $ 2,139 $ – $ – $ – $ – $ – Property lease revenues   20,715   16,927   13,250   9,834   7,102   58,379 Total $ 22,854 $ 16,927 $ 13,250 $ 9,834 $ 7,102 $ 58,379   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. Life insurance premiums are recognized in accordance with existing guidance in Topic 944 – Financial Services – Insurance. Property and casualty insurance premiums are recognized as revenue over the policy periods. Interest and investment income are recognized as earned. Property and casualty premiums are recognized in accordance with existing guidance in Topic 944 – Financial Services – Insurance. F- 62     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. Net investment and interest income was recognized in accordance with existing guidance in Topic 825 – Financial Instruments.   In the following tables, the revenue is disaggregated by timing of revenue recognition:     Years Ended March 31,     2020   2019   2018           (In thousands)               Revenues recognized over time $ 147,565 $ 2,814,732 $ 2,617,990 Revenues recognized at a point in time   309,804   305,408   301,152 Total revenues recognized under ASC 606   457,369   3,120,140   2,919,142               Revenues recognized under ASC 842 or 840   3,182,902   406,070   353,924 Revenues recognized under ASC 944   200,768   131,563   217,575 Revenues recognized under ASC 320   137,829   110,934   110,473 Total revenues $ 3,978,868 $ 3,768,707 $ 3,601,114 In the above tables, the revenues recognized over time include self-moving equipment rentals, property management fees, the shipping fees associated with U-Box rentals and a portion of other revenues for fiscal 2019 and 2018, respectively. Whereas revenues recognized at a point in time include self-moving and self-storage products and service sales and a portion of other revenues. Self-moving equipment rentals are now in revenues recognized under ASC 842/840 as of April 1, 2019. We recognized liabilities resulting from contracts with customers for self-moving equipment rentals, self-storage revenues, U-Box revenues and tenant revenue, 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. Note 24.   Subsequent Events Our management has evaluated subsequent events occurring after March 31, 2020. We do not believe any other subsequent events have occurred that would require further disclosure or adjustment to our financial statements other than as stated below. In April 2020, Oxford paid AMERCO a cash dividend of $ 18.6 million. In April 2020, we expanded our corporate revolver by an additional $ 50.0 million and fully borrowed that as well. In May 2020, we entered into a one-year term loan totaling $ 200.0 million at a rate of one-month LIBOR plus a 2.00 % margin. This loan is secured by the Company’s claims for federal income tax refund, to further strengthen our liquidity position. F- 63
