SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation – The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries as well as its non-wholly owned subsidiaries, Contrail Aviation and Delphax. All intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications have been made to the prior period amounts to conform to the current presentation. Accounting Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts of assets and liabilities and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. COVID-19 and its impact on the current financial, economic and capital markets environment, and future developments in these and other areas present uncertainty and risk with respect to our financial condition and results of operations. Each of our businesses implemented measures to attempt to limit the impact of COVID-19 but we still experienced a number of disruptions, and we experienced and continue to experience a reduction in demand for commercial aircraft, jet engines and parts compared to historical periods. We currently expect that many of our businesses may continue to generate reduced operating cash flow and may operate at a loss during at least the first half of fiscal 2022 and potentially even longer. We expect that these impacts will continue to some extent if the outbreak persists. The fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19 on economic and market conditions, and, as a result, present material uncertainty and risk with respect to us and our results of operations. The Company believes the estimates and assumptions underlying the Company’s consolidated financial statements are reasonable and supportable based on the information available as of March 31, 2021, however; uncertainty over the ultimate impact COVID-19 will have on the global economy generally, and the Company’s business in particular, makes any estimates and assumptions as of March 31, 2021 inherently less certain than they would be absent the current and potential impacts of COVID-19. Segments - The Company has four reportable operating segments: overnight air cargo, ground equipment sales, commercial jet engine and parts and corporate and other. The Company assesses the performance of these segments on an individual basis (see Note 21 ). Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The Company’s Chief Executive Officer reviews financial information by business segment for purposes of allocating resources and evaluating financial performance. Each business segment has separate management teams and infrastructures that offer different products and services. We evaluate the performance of our business segments based on operating income. Variable Interest Entities – In accordance with the applicable accounting guidance for the consolidation of variable interest entities, the Company analyzes its variable interests to determine if an entity in which we have a variable interest is a variable interest entity. Our analysis includes both quantitative and qualitative reviews to determine if we must consolidate a variable interest entity as its primary beneficiary. Business Combinations – The Company accounts for business combinations in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations . Consistent with ASC 805, the Company accounts for each business combination by applying the acquisition method. Under the acquisition method, the Company records the identifiable assets acquired and liabilities assumed at their respective fair values on the acquisition date. Goodwill is recognized for the excess of the purchase consideration over the fair value of identifiable net assets acquired. Included in purchase consideration is the estimated acquisition date fair value of any earn-out obligation incurred. For business combinations where non-controlling interests remain after the acquisition, assets (including goodwill) and liabilities of the acquired business are recorded at the full fair value and the portion of the acquisition date fair value attributable to non-controlling interests is recorded as a separate line item within the equity section or, as applicable to redeemable non-controlling interests, between the liabilities and equity sections of the Company’s consolidated balance sheets . The acquisition method permits the Company a period of time after the acquisition date during which the Company may adjust the provisional amounts recognized in a business combination. This period of time is referred to as the “measurement period”. The measurement period provides an acquirer with a reasonable time to obtain the information necessary to identify and measure the assets acquired and liabilities assumed. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports in its consolidated financial statements provisional amounts for the items for which the accounting is incomplete. Accordingly, the Company is required to recognize adjustments to the provisional amounts, with a corresponding adjustment to goodwill, in the reporting period in which the adjustments to the provisional amounts are determined. Thus, the Company would adjust its consolidated financial statements as needed, including recognizing in its current-period earnings the full effect of changes in depreciation, amortization, or other income effects, by line item, if any, as a result of the change to the provisional amounts calculated as if the accounting had been completed at the acquisition date. Income statement activity of an acquired business is reflected within the Company’s consolidated statements of income commencing with the date of acquisition. Amounts for pre-acquisition periods are excluded. Acquisition-related costs are costs the Company incurs to affect a business combination. Those costs may include such items as finder’s fees, advisory, legal, accounting, valuation, and other professional or consulting fees, and general administrative costs. The Company accounts for such acquisition-related costs as expenses in the period in which the costs are incurred and the services are received. Changes in estimate of the fair value of earn-out obligations subsequent to the acquisition date are not accounted for as part of the acquisition, rather, they are recognized directly in earnings. Cash and Cash Equivalents – Cash equivalents consist of liquid investments with maturities of three months or less when purchased. Financial Instruments Designated for Trading – Except for short sales of equity securities, the Company accounts for all other financial instruments (including derivative instruments) designated for trading in accordance with ASC 815. All changes in the fair value of the financial instruments designated for trading are recognized in earnings as they occur. Further, all gains and losses on derivative instruments designated for trading are presented net on the consolidated Statements of Income (Loss). The fair value of derivative instruments designated for trading in a gain position are recorded in Other Current Assets and the fair value of derivative instruments designated for trading in a loss position are recorded in Accrued Expenses and Other on the consolidated Balance Sheets. The Company accounts for short sales of equity securities in accordance with ASC 942 and ASC 860. The obligations incurred in short sales are reported in Accrued Expenses and Other on the consolidated Balance Sheets. They are subsequently measured at fair value through the income statement at each reporting date with gains and losses on securities. Interest on the short positions are accrued periodically and reported as interest expense. The market value of the Company’s equity securities and cash held by the broker are used as collateral against any outstanding margin account borrowings for purposes of short selling equities. This collateral is recorded in Other Current Assets on the consolidated Balance Sheets. The Company reports all cash receipts and payments resulting from the purchases and sales of securities, loans, and other assets that are acquired specifically for resale as operating cash flows. Inventories – Inventories are carried at the lower of cost or net realizable value. When finished goods units are leased to customers under operating leases, the units are transferred to Assets on Lease or Held For Lease. The classification of cash flows associated with the purchase and sale of finished goods is based on the activity that is likely to be the predominant source or use of cash flows for the items. Consistent with aviation industry practice, the Company includes expendable aircraft parts and supplies in current assets, although a certain portion of these inventories may not be used or sold within one year. The Company periodically evaluates the carrying value of inventory. In these evaluations, the Company is required to make estimates regarding the net realizable value, which includes the consideration of sales patterns and expected future demand. Any slow moving, obsolete or damaged inventory and inventory with costs exceeding net realizable value are evaluated for write-downs. These estimates could vary significantly from actual amounts based upon future economic conditions, customer inventory levels, or competitive factors that were not foreseen or did not exist when the estimated write-downs were made. In accordance with industry practice, all inventories are classified as a current asset including portions with long production cycles, some of which may not be realized within one year. Investments under the Equity Method – The Company utilizes the equity method to account for investments when the Company possesses the ability to exercise significant influence, but not control, over the operating and financial policies of the investee. The ability to exercise significant influence is presumed when an investor possesses more than 20% of the voting interests of the investee. This presumption may be overcome based on specific facts and circumstances that demonstrate that the ability to exercise significant influence is restricted. The Company applies the equity method to investments in common stock and to other investments when such other investments possess substantially identical subordinated interests to common stock. For investments that have a different fiscal year-end, if the difference is not more than three months, the Company elects a 3-month lag to record the change in the investment. The Company assesses the carrying value of its investments whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The recoverability is measured by comparing the carrying amount of the investment to the estimated future undiscounted cash flows of the investment, which take into account current, and expectations for future, market conditions and the Company’s intent with respect to holding or disposing of the investment. Changes in economic and operating conditions, including those occurring as a result of the impact of the COVID-19 pandemic, that occur subsequent to a current impairment analysis and the Company’s ultimate use of the investment could impact the assumptions and result in future impairment losses to the investments. If the Company’s analysis indicates that the carrying value is not recoverable on an undiscounted cash flow basis, the Company will recognize an impairment loss for the amount by which the carrying value exceeds the fair value. The fair value is determined through quoted prices in active markets or various valuation techniques, including internally developed discounted cash flow models or comparable market transactions. Goodwill - The Company evaluates goodwill on an annual basis or anytime events or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company is permitted to first assess qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying value, including goodwill. In qualitatively evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company assesses relevant events and circumstances such as macroeconomic conditions, industry and market developments, cost factors, and the overall financial performance of the reporting unit. If, after assessing these events and circumstances, it is determined that there may be an impairment, then a quantitative analysis is performed. In the first step of the quantitative method, recoverability of goodwill is evaluated by estimating the fair value of the reporting unit’s goodwill using multiple techniques, including a discounted cash flow model income approach and a market approach. The estimated fair value is then compared to the carrying value of the reporting unit. The Company will recognize an impairment charge for the amount by which the carrying value of the reporting unit exceeds its fair value, if any. Goodwill consisted of the following (in thousands): Year Ended March 31, 2021 2020 Goodwill, at original cost $ 4,603 $ 4,603 Less accumulated impairment (376) (376) Goodwill, net of impairment $ 4,227 $ 4,227 As of March 31, 2021, the entire $4.2 million goodwill balance is attributable to the acquisition of Contrail Aviation and included within the Commercial Jet Engines and Parts segment. We performed our annual impairment assessment for goodwill of the Contrail reporting unit at March 31, 2021. In the fiscal year 2021, COVID-19 greatly impacted the macroeconomic conditions and the outlook of the airline industry. Due to this, the Company performed a quantitative analysis using a combination of the income approach, utilizing a discounted cash flow analysis, and the market approach, utilizing the guideline public company method. Contrail's discounted cash flow analysis requires significant management judgment with respect to forecasts of revenue, operating margins, capital expenditures, and the selection and use of an appropriate discount rate. The forecasts and assumptions are based on our annual and long-term business plans. Contrail’s market approach requires management to make significant assumptions related to market multiples of revenue and earnings derived from comparable publicly-traded companies with similar operating characteristics as Contrail. Based on the results of our annual quantitative assessment conducted as of March 31, 2021, the fair value of our Contrail reporting unit exceeded its carrying value, and management concluded that no impairment charge was warranted. Intangible Assets – Amortizable intangible assets consist of acquired patents, tradenames, customer relationships, and other finite-lived identifiable intangibles. Such intangibles are initially recorded at fair value and subsequently subject to amortization. Amortization is recorded using the straight-line method over the estimated useful lives of the assets. In accordance with the applicable accounting guidance, the Company evaluates the recoverability of amortizable intangible assets whenever events occur that indicate potential impairment. In doing so, the Company assesses whether the carrying amount of the asset is unrecoverable by estimating the sum of the future cash flows expected to result from the asset, undiscounted and without interest charges. If the carrying amount is more than the recoverable amount, an impairment charge must be recognized based on the estimated fair value of the asset. The estimated amortizable lives of the intangible assets are as follows: Years Software 3 Trade names 5 Certification 5 Non-compete 5 License 5 Patents 9 Customer relationship 10 Property and Equipment and Assets on Lease or Held for Lease – Property and equipment is stated initially at cost, or fair value if purchased as part of a business combination. Depreciation and amortization are provided on a straight-line basis over the asset’s useful life. Equipment leased to customers is depreciated using the straight line method. Useful lives range from three years for computer equipment, seven years for flight equipment, ten years for deicers and other equipment leased to customers and thirty years for buildings. Engine assets on lease or held for lease are stated at cost, less accumulated depreciation. Certain costs incurred in connection with the acquisition of engine assets are capitalized as part of the cost of such assets. If assets are not actively being leased (i.e. held for lease), then they are not being depreciated. Major overhauls which improve functionality or extend original useful life are capitalized and depreciated over the engine assets' useful life to a residual value. The Company depreciates the engines on a straight-line basis over the assets' useful life from the acquisition date to a residual value. The Company adjusts its estimates annually for these older generation assets, including updating estimates of an engine’s or aircraft’s remaining operating life. The Company believes this methodology accurately reflects the typical holding period for the assets and, that the residual value assumption, which is dependent on the Company's eventual plan for the engine assets (i.e. whole asset sale, part-out, etc.), reasonably approximates the selling price of the assets. When engine assets are committed for sales, the assets are transferred to Inventory. The classification of cash flows associated with the purchase and sale of engine assets is based on the activity that is likely to be the predominant source or use of cash flows for the items. The Company assesses long-lived assets for impairment when events and circumstances indicate the assets may be impaired and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amount. When evaluating the future cash flows that an asset will generate, we make assumptions regarding the lease market for specific engine models, including estimates of market lease rates and future demand. These assumptions are based upon lease rates that we are obtaining in the current market as well as our expectation of future demand for the specific engine/aircraft model. We determine fair value of the assets by reference to independent appraisals, quoted market prices (e.g., an offer to purchase) and other factors such as current data from manufacturers as well as specific market sales. In the event it is determined that the carrying values of long-lived assets are in excess of the estimated undiscounted cash flows from those assets, the Company then will write-down the value of the assets by the excess of carrying value over fair value. Accounting for Debt - Trust Preferred Securities and Warrant Liability – On June 10, 2019, the Company issued an aggregate of 1.6 million TruPs in the amount of $4.0 million in a non-cash transaction. These TruPs are mandatorily redeemable preferred security obligations of the Company. In accordance with ASC 480, the Company presented mandatorily redeemable preferred securities that do not contain a conversion option as a liability on the balance sheet. In connection with the issuance of the TruPs, the Company also issued an aggregate of 8.4 million warrants (representing warrants to purchase $21.0 million in stated value of TruPs). A warrant for mandatorily redeemable shares conditionally obligates the issuer to ultimately transfer assets—the obligation is conditioned only on the warrant's being exercised because the shares will be redeemed. Thus, warrants for mandatorily redeemable shares are liabilities under ASC 480. Accordingly, the Warrants are recorded within "Other non-current liabilities" on our consolidated balance sheets. As of March 31, 2021, the Warrants are recorded at fair value. Fair value measurement was based on quoted price for a similar asset or liability as observed on the NASDAQ Global Market. The liability is classified as Level 2 in the hierarchy. See Note 5 . Income Taxes – Income taxes have been provided using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax laws and rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. A valuation allowance against net deferred tax assets is recorded when it is more likely than not that such assets will not be fully realized. Tax credits are accounted for as a reduction of income taxes in the year in which the credit originates. All deferred income taxes are classified as non-current in the consolidated balance sheets. The Company recognizes the benefit of a tax position taken on a tax return, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. An uncertain income tax position is not recognized if it has a less than a 50% likelihood of being sustained. Accounting for Redeemable Non-Controlling Interest – In 2016, in connection with the Company's acquisition of Contrail Aviation, Contrail Aviation entered into an Operating Agreement (the “Operating Agreement”) with the Seller providing for the governance of and the terms of membership interests in Contrail Aviation. The Operating Agreement includes put and call options (“Put/Call Option”) with regard to the 21% non-controlling interest retained by the Seller. The Seller is the founder of Contrail Aviation and its current Chief Executive Officer. The Put/Call Option permits the Seller to require Contrail Aviation to purchase all of the Seller’s equity membership interests in Contrail Aviation commencing on the fifth anniversary of the acquisition, which is on July 18, 2021. Per the agreement, the price is to be agreed upon by the parties or, failing such agreement, to be determined pursuant to third-party appraisals in a process specified in the agreement. Applicable accounting guidance requires an equity instrument that is redeemable for cash or other assets to be classified outside of permanent equity if it is redeemable (a) at a fixed or determinable price on a fixed or determinable date, (b) at the option of the holder, or (c) upon the occurrence of an event that is not solely within the control of the issuer. As a result of this feature, the Company recorded the non-controlling interest as redeemable and classified it in temporary equity within its Consolidated Balance Sheets initially at its acquisition-date fair value. The non-controlling interest is adjusted each reporting period for income (or loss) attributable to the non-controlling interest as well as any applicable distributions made. A measurement period adjustment, if any, is then made to adjust the non-controlling interest to the higher of the redemption value (fair value) or carrying value each reporting period. These fair value adjustments are recognized through retained earnings and are not reflected in the Company's Consolidated Statements of Income. When calculating earnings per share attributable to the Company, the Company adjusts net income attributable to the Company for the measurement period adjustment to the extent the redemption value exceeds the fair value of the non-controlling interest on a cumulative basis. The fair value of the non-controlling interest is determined using a combination of the income approach, utilizing a discounted cash flow analysis, and the market approach, utilizing the guideline public company method. Contrail's discounted cash flow analysis requires significant management judgment with respect to forecasts of revenue, operating margins, capital expenditures, and the selection and use of an appropriate discount rate. The forecasts and assumptions are based on our annual and long-term business plans. Contrail’s market approach requires management to make significant assumptions related to market multiples of earnings derived from comparable publicly-traded companies with similar operating characteristics as Contrail. As of March 31, 2021, the fair value of the redeemable non-controlling interest is $6.6 million. The net change in the redemption value compared to March 31, 2020 is an increase of $0.5 million. The increase was driven by $2.9 million related to the net change in fair value during the fiscal year ended March 31, 2021, which is reflected on our consolidated statements of equity, partially offset by net loss attributable to and distributions made to the non-controlling interest. See Note 5 . The fair value increase is primarily attributable to the value associated with Contrail's potential investment in an aircraft asset management joint venture, which subsequently closed on May 5, 2021. See Note 24 . Revenue Recognition – Substantially all of the Company’s revenue is derived from contracts with an initial expected duration of one year or less. As a result, the Company has applied the practical expedient to exclude consideration of significant financing components from the determination of transaction price, to expense costs incurred to obtain a contract, and to not disclose the value of unsatisfied performance obligations.We evaluate gross versus net presentation on revenues from products or services purchased and resold in accordance with the revenue recognition criteria outlined in ASC 606-10, Principal Agent Considerations. The Company, under the terms of its overnight air cargo dry-lease service contracts, passes through to its air cargo customer certain cost components of its operations without markup. The cost of fuel, landing fees, outside maintenance, parts and certain other direct operating costs are included in operating expenses and billed to the customer, at cost, and included in overnight air cargo revenue on the accompanying statements of income. These pass-through costs totaled $19.9 million and $23.7 million for the years ended March 31, 2021 and 2020, respectively. Liquidity – The Company’s Credit Agreement with MBT (the Air T debt in Note 13 ) includes several covenants that are measured once a year at March 31, including, but not limited to, a financial covenant requiring a debt service coverage ratio of 1.25. The AirCo 1 Credit Agreement (the AirCo 1 debt in Note 13 ) contains an affirmative covenant relating to collateral valuation. As of March 31, 2021, the Company and AirCo 1 were in compliance with all financial covenants. The Contrail Credit Agreement (the Contrail debt in Note 13 ) contains affirmative and negative covenants, including covenants that restrict the ability of Contrail and its subsidiaries to, among other things, incur or guarantee indebtedness, incur liens, dispose of assets, engage in mergers and consolidations, make acquisitions or other investments, make changes in the nature of its business, and engage in transactions with affiliates. The Contrail Credit Agreement also contains quarterly financial covenants applicable to Contrail and its subsidiaries, including a minimum debt service coverage ratio of 1.25 to 1.0 and a minimum TNW of $15 million. On September 25, 2020, Contrail entered into a Third Amendment to Supplement #2 to Master Loan Agreement dated June 24, 2019 with Old National Bank ("ONB"). The material changes within the Third Amendment were: (a) to extend the date for compliance with the provision where Contrail is required to pay down the total outstanding principal balance of its revolver to zero for at least thirty consecutive days to September 5, 2021; and (b) to extend the date for compliance with the required quarterly debt service coverage ratio covenant such that Contrail shall commence compliance with the covenant commencing on March 31, 2022 and on the last day of each fiscal quarter thereafter. Due primarily to the impact of COVID-19 on its business, as of March 31, 2021, Contrail was not in compliance with maintaining the minimum TNW of $15 million. As of the issuance date of this report, pursuant to the existing terms of the Contrail Credit Agreement, the Company and the non-controlling interest owner of Contrail made total capital contributions to Contrail in the amount of $1.4 million, which had the effect of curing this financial covenant non-compliance. Contrail and ONB are also in discussions to reduce the minimum TNW to $8 million, in exchange for certain amendments to its credit agreement, including renewing its revolving line of credit at a lower amount than the current agreement. However, there is no assurance that Contrail will be successful in reducing the minimum TNW financial covenant. The obligations of Contrail under the Contrail Credit Agreement are guaranteed by the Company, up to a maximum of $1.6 million, plus costs of collection. The Company is not liable for any other assets or liabilities of Contrail and there are no cross-default provisions with respect to Contrail’s debt in any of the Company’s debt agreements with other lenders. In the possible absence of Contrail’s operation as a going concern, the Company believes it, along with the rest of its businesses, will continue to operate as a going concern, given the maximum guarantee of Contrail’s obligations of $1.6 million. On November 24, 2020, Contrail and ONB entered into Supplement #8 to Master Loan Agreement and related documentation for a loan in the aggregate amount of $43.6 million for which ONB served as lender pursuant to the Main Street Priority Loan Facility as established by the U.S. Federal Reserve. The Contrail Main Street Loan was approved by the Fed and completed by December 8, 2020. The proceeds were used to pay down the Contrail Revolver. The loan proceeds are also to be used as working capital to support the operations of Contrail in the ordinary course of business, which includes the acquisition from time to time of aircraft and engines. The indebtedness incurred is subject to the terms and provisions of the Master Loan Agreement. The principal terms of the Contrail Main Street Loan are detailed in Note 13 . On December 11, 2020, AirCo 1 and PSB entered into a loan in the aggregate amount of $6.2 million for which PSB served as lender pursuant to the Main Street Priority Loan Facility as established by the Fed. The AirCo 1 Main Street Loan was approved by the Fed and completed by December 22, 2020. The loan proceeds were used to pay off the AirCo 1 revolving line of credit with MBT. The principal terms of the Term Loan - PSB are detailed in Note 13 . The revolving line of credit at Air T with MBT has a due date or expires within the next twelve months. We are currently seeking to refinance this obligation prior to August 31, 2021; however, there is no assurance that we will be able to execute this refinancing or, if we are able to refinance this obligation, that the terms of such refinancing would be as favorable as the terms of our existing credit facility. In April 2020, the Company obtained loans under the Payroll Protection Program ("PPP loan"), as authorized by the CARES Act, of $8.2 million to help pay for payroll costs, mortgage interest, rent and utility costs. The Company has applied to MBT for forgiveness of the PPP Loan; however, forgiveness is not fully assured. The Company believes it is probable that the cash on hand (including that obtained from the PPP and other current financings), net cash provided by operations from its remaining operating segments, together with its current revolving lines of credit, as amended or replaced, will be |
