Accounting Policies [Abstract]
Principles of Consolidation	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	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	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	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	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 and Cash Equivalents – Cash equivalents consist of liquid investments with maturities of three months or less when purchased.
Financial Instruments Designated For Trading	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 – 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	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	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.
Intangible Assets	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.
Property and Equipment and Assets on Lease or Held for Lease	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	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 Tax	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	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.
Revenue Recognition	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.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard significantly changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income, including trade receivables. The standard requires an entity to estimate its lifetime “expected credit loss” for such assets at inception, and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The Company adopted this standard on April 1, 2020. As of March 31, 2021, the standard did not have a material impact on the Company's consolidated financial statements and disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies how an entity is required to test goodwill for impairment by eliminating Step Two from the goodwill impairment test. Step Two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, an entity will recognize an impairment charge for the amount by which the carrying value of a reporting unit exceeds its fair value. The Company adopted this amendment on April 1, 2020. As of March 31, 2021, the amendment did not have a material impact on the Company's consolidated financial statements and disclosures. In October 2018, the FASB updated the Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities of the Accounting Standards Codification. The amendments in this update affect reporting entities that are required to determine whether they should consolidate a legal entity under the guidance within the Variable Interest Entities Subsections of Subtopic 810-10, Consolidation—Overall. Indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The Company adopted this amendment on April 1, 2020. As of March 31, 2021, the amendment did not have a material impact on the Company's consolidated financial statements and disclosures. In December 2019, the FASB updated the Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes of the Accounting Standards Codification. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The amendments in this Update simplify the accounting for income taxes by removing the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income), among other changes. The Company early adopted this amendment as of April 1, 2020. The amendment resulted in an immaterial impact to its consolidated financial statements and disclosures. Recently Issued Accounting Pronouncements In January 2020, the FASB updated the Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The Company is currently evaluating the impact of this amendment on its consolidated financial statements and disclosures. In March 2020, the FASB issued ASU 2020-04- Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this Update provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Further, in accordance with the amendments in this Update, an entity may make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The amendments are effective for all entities from the beginning of an interim period that includes the issuance date of this ASU. An entity may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact of this amendment on our contracts, hedging relationships, and other transactions affected by reference rate reform.

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.

Cash and Cash Equivalents

Cash and Cash Equivalents – Cash equivalents consist of liquid investments with maturities of three months or less when purchased.

Financial Instruments Designated For Trading

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 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

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.

Intangible Assets

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.

Property and Equipment and Assets on Lease or Held for Lease

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

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 Tax

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

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.

Revenue Recognition

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.

Recently Adopted and Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard significantly changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income, including trade receivables. The standard requires an entity to estimate its lifetime “expected credit loss” for such assets at inception, and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The Company adopted this standard on April 1, 2020. As of March 31, 2021, the standard did not have a material impact on the Company's consolidated financial statements and disclosures.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies how an entity is required to test goodwill for impairment by eliminating Step Two from the goodwill impairment test. Step Two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under this standard, an entity will recognize an impairment charge for the amount by which the carrying value of a reporting unit exceeds its fair value. The Company adopted this amendment on April 1, 2020. As of March 31, 2021, the amendment did not have a material impact on the Company's consolidated financial statements and disclosures.

In October 2018, the FASB updated the Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities of the Accounting Standards Codification. The amendments in this update affect reporting entities that are required to determine whether they should consolidate a legal entity under the guidance within the Variable Interest Entities Subsections of Subtopic 810-10, Consolidation—Overall. Indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. The Company adopted this amendment on April 1, 2020. As of March 31, 2021, the amendment did not have a material impact on the Company's consolidated financial statements and disclosures.

In December 2019, the FASB updated the Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes of the Accounting Standards Codification. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The amendments in this Update simplify the accounting for income taxes by removing the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income), among other changes. The Company early adopted this amendment as of April 1, 2020. The amendment resulted in an immaterial impact to its consolidated financial statements and disclosures.

Recently Issued Accounting Pronouncements

In January 2020, the FASB updated the Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The Company is currently evaluating the impact of this amendment on its consolidated financial statements and disclosures.

In March 2020, the FASB issued ASU 2020-04- Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this Update provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. Further, in accordance with the amendments in this Update, an entity may make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The amendments are effective for all entities from the beginning of an interim period that includes the issuance date of this ASU. An entity may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact of this amendment on our contracts, hedging relationships, and other transactions affected by reference rate reform.
