Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and include the accounts of Harbor Diversified, Inc. (Harbor) and subsidiaries (collectively, the Company).
Harbor
is a non-operating holding company
that is the parent of a consolidated group of subsidiaries, including AWAC Aviation, Inc. (AWAC), the sole member of Air Wisconsin Airlines LLC (Air Wisconsin), which is a regional air carrier. Harbor is also the direct parent of three other subsidiaries: (1) Lotus Aviation Leasing, LLC (Lotus), which leases flight equipment to Air Wisconsin, (2) Air Wisconsin Funding LLC (AWF), which provides flight equipment financing to Air Wisconsin, and (3) Harbor Therapeutics, Inc. (Therapeutics), which
is a non-operating entity with
no material assets.
The consolidated financial statements have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the following disclosures are adequate to make the information presented not misleading. The consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly in all material respects the financial condition and results of operations for the interim periods presented. All adjustments are of a normal recurring nature, unless otherwise disclosed. All of the dollar and share amounts set forth in these condensed notes to consolidated financial statements are presented in thousands except per share and par value amounts.
These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Harbor’s Annual Report on Form
10-K
for the year ended December 31, 2021, which was filed with the SEC on March 30, 2022 (2021 Annual Report). Due in part to the significant impacts to the Company’s business and industry from the industry-wide pilot shortage and the global coronavirus
(COVID-19)
pandemic, in addition to other factors, the results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for any other reporting period.
Description of Operations
Description of Operations
The Company has principal lines of business focused on (1) providing regional air services through Air Wisconsin (airline business), (2) acquiring flight equipment for the purpose of leasing the equipment to Air Wisconsin, and (3) providing flight equipment financing to Air Wisconsin.
The airline business is operated entirely through Air Wisconsin, which is an independent regional air carrier that is engaged in the business of providing scheduled passenger service under a capacity purchase agreement (United capacity purchase agreement) with United Airlines, Inc. (United) that was entered into in February 2017 and amended in October 2020, April 2021, April 2022, and June 2022. United is currently Air Wisconsin’s sole airline partner. For additional information, refer to Note 3,
Capacity Purchase Agreement with United.
Air Wisconsin operates as a United Express carrier with a presence at both Chicago O’Hare and Washington-Dulles, two of United’s key domestic hubs.
 
Contract Revenues
Contract Revenues
The Company recognizes revenue under the United capacity purchase agreement over time as services are provided. United pays Air Wisconsin a fixed rate for each departure and block hour (measured from takeoff to landing, including taxi time), and a fixed amount per aircraft per day, with incentive payments available, and penalties payable, based on the achievement, or failure to achieve, certain performance criteria. Under the agreement, Air Wisconsin’s performance obligation is met and revenue is recognized over time, which is then reflected in contract revenues. The agreement also provides for the reimbursement to Air Wisconsin of certain direct operating expenses such as hull and liability insurance, property taxes and Canadian navigational fees.
United makes provisional cash payments to Air Wisconsin during each month of service based on projected flight schedules. These provisional cash payments are subsequently reconciled with United based on actual completed flight activity. As of the date of this filing, these payments are reconciled through January 2022. Subject to final reconciliation of the provisional cash payments for the periods after January 31, 2022, as of June 30, 2022,
United owed Air Wisconsin approximately $14,185, which is recorded in accounts receivable, net, on the consolidated balance sheets. United is
disputing that it owes $10,462 of this amount. For additional information regarding the dispute with United, refer to Note 8,
Commitments and Contingencies.
Under the United capacity purchase agreement, Air Wisconsin is eligible to receive incentive payments, or may be required to pay penalties, upon the achievement of, or failure to achieve, certain performance criteria primarily based on flight completion,
on-time
performance, and customer satisfaction ratings. The incentives are defined in the agreement and performance is measured on a monthly basis. At the end of each month during the term of the agreement, Air Wisconsin calculates the incentives achieved, or penalties payable, during that period and recognizes revenue accordingly, subject to the variable constraint guidance under Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 606,
Revenue from Contracts with Customers
(Topic 606). Although the final reconciliations have not been completed for all periods, after considering operational performance related to expected incentive and penalty payments, Air Wisconsin has received, or
believes it 
is likely to receive, incentive payments, net of penalties, of $2,530 and $1,340 for the three months ended June 30, 2022 and 2021, respectively, and $3,307 and $3,159 for the six months ended June 30, 2022 and 2021, respectively. These amounts are recorded in accounts receivable, net, on the consolidated balance sheets.
Under the United capacity purchase agreement, Air Wisconsin is paid a fixed amount per aircraft per day for each month during the term of the agreement. In accordance with GAAP, the Company recognizes revenue related to the fixed payments on a proportional basis taking into account the number of flights actually completed in that period relative to the number of flights expected to be completed in subsequent periods during the remaining term of the agreement. Air Wisconsin deferred fixed revenues between April 2020 and June 2021 due to the significant decrease in its completed flights as a result of the
COVID-19
pandemic. Beginning in July 2021, due to an increase in completed flights and based on projected future completed flight activity, Air Wisconsin began reversing this deferral of fixed revenues, and it anticipates continuing to do so through February 2023, the end of the contract period. Accordingly, during the three and six months ended June 30, 2022, Air Wisconsin recognized $12,632 and $17,368, respectively, of fixed revenues that were previously deferred, compared to a deferral of $7,440 and $15,351 of fixed revenues in the three and six months ended June 30, 2021, respectively. Air Wisconsin’s deferred revenues related to the fixed portion of revenue under the United capacity purchase agreement will adjust over the remaining contract term based on the number of flights completed in each reporting period relative to the number of flights anticipated to be completed over the remaining contract term. As of June 30, 2022, deferred fixed revenues in the amount of $27,470 were recorded as part of deferred revenues on the consolidated balance sheets.
Consistent with the discussion above, for the three and six months ended June 30, 2022, as compared to the three and six months ended June 30, 2021, Air Wisconsin also recognized increased
non-refundable
upfront fee revenues and increased fulfillment costs, both of which are amortized over the remaining term of the United capacity purchase agreement in proportion to the number of flights actually completed in that period relative to the number of flights expected to be completed in subsequent periods. During the three and six months ended June 30, 2022, Air Wisconsin recorded $1,316 and $2,383 of revenue from upfront fees and $141 and $256 of fulfillment costs, respectively, compared to $685 and $1,346 in revenue from upfront fees and $73 and $144 of fulfillment costs for the three and six months ended June 30, 2021, respectively. As of June 30, 2022, deferred upfront fee revenue in the amount of $3,338, is recorded as part of contract liabilities on the consolidated balance sheets.
As part of the October 2020 amendment to the United capacity purchase agreement (CPA Amendment), United made a cash settlement payment of $670 and issued a note receivable to Air Wisconsin in the amount of $11,048, of which $4,410 was deferred as of December 31, 2020, with the remaining portion to be recognized in proportion to the number of flights expected to be completed in subsequent periods. In October 2021, in accordance with the CPA Amendment, Air Wisconsin received $294 from United for the opening of a crew base, of which $73 was deferred as of December 31, 2021. For the three and six months ended June 30, 2022, Air Wisconsin recorded $640 and $1,159 of revenue related to these items, respectively, compared to $324 and $637 of revenue related to these items for the three and six months ended June 30, 2021, respectively. As of June 30, 2022, deferred CPA Amendment revenue in the amount of $1,623, is recorded as part of contract liabilities on the consolidated balance sheets.
 
The timing of the recognition of deferred fixed revenue,
non-refundable
upfront fee revenue, fulfillment costs, and deferred CPA Amendment revenue in future periods is subject to considerable uncertainty due to a number of factors, including the actual number of completed flights in any particular period relative to the estimated number of flights anticipated to be flown over the contract term.
The amount of revenues recognized for the three and six months ended June 30, 2022 that were previously recorded as contract liabilities were $14,588 and $20,909, respectively.
The CPA Amendment provided, among other things, for the payment or accrual of certain amounts by United to Air Wisconsin based on certain scheduling benchmarks. In conjunction with the significant reduction in departures and block hours resulting from the
COVID-19
pandemic in 2020, and consistent with the terms of the CPA Amendment, management determined that, from an accounting perspective, a new performance obligation was created by United, requiring Air Wisconsin to stand ready to deliver flight services. Air Wisconsin determined, using the expected cost plus a margin method, that the United “stand ready” rate represents the relative stand-alone selling price of the performance obligation. The stand ready performance obligation will be recognized over time on a straight-line basis based on the number of unscheduled block hours below a minimum threshold at the stand ready rate as determined in a manner consistent with the CPA Amendment. For the three and six months ended June 30, 2022, Air Wisconsin recorded $4,099 and $7,608, respectively, in revenue related to this performance obligation compared to $5,736 and $12,972 for the three and six months ended June 30, 2021, respectively. Under the CPA Amendment, United is required to pay this amount by the delivery of a note each quarter
,
 
which notes are
due and payable
at the end of the contract term in February 2023. Therefore, this amount was recorded in notes receivable on the consolidated balance sheets. The notes receivable contain a significant financing component and any interest income is separately reported in the consolidated statements of operations. As of June 30, 2022,
the principal amount of
these notes totaled $55,177, bore interest at the rate of 4.5%, and had a maturity date of February 28, 2023. As of June 30, 2022, interest receivable on these notes totaled $3,303. United has disputed that it owes these amounts in respect of certain quarters and has refused to deliver notes for those quarters. The amount in dispute in respect of those notes as of the date of this filing totals $9,109, including interest receivable of $71. For additional information regarding the dispute with United, refer to Note 8,
Commitments and Contingencies.
Other Revenues
Other Revenues
Other revenues primarily consist of the sales of parts to other airlines and are immaterial in all periods presented. The transaction price for the sale of these parts generally is fair market value.
Restricted Cash
Restricted Cash
As of June 30, 2022, the Company had a restricted cash balance of $516. A portion of the balance secures a credit facility for the issuance of letters of credit guaranteeing the performance of Air Wisconsin’s obligations under certain lease agreements, airport agreements and insurance policies. The remaining portion is cash held for the repurchase of shares under Harbor’s stock repurchase program. For additional information, refer to Note 8,
Commitments and Contingencies
, and Note 13,
Stock Repurchase Program.
Marketable Securities
Marketable Securities
The Company’s equity security investments, consisting of exchange-traded funds and mutual funds, are recorded at fair value based on quoted market prices (Level 1) in marketable securities on the consolidated balance sheets, in accordance with the guidance in ASC Topic 321,
Investments-Equity Securities
, with the change in fair value during the period included in the consolidated statements of operations. As of June 30, 2022 the fair value of the Company’s marketable securities was $133,303.
The calculation of net unrealized gains and losses that relate to marketable securities held as of June 30, 2022 is as follows:

Air Wisconsin’s capitalized engine maintenance costs are amortized over their estimated useful life measured in remaining engine cycles to the next scheduled shop visit. Lotus’ engine maintenance costs are expensed.
For the three- and six-month periods ended June 30, 2022, the Company recorded depreciation expense of $6,218 and
 $12,433
, respectively, compared
to $6,246 and $12,495 for the three- and six-month periods ended June 30, 2021, respectively. 
Impairment of Long-Lived and Intangible Assets
Impairment of Long-Lived and Intangible Assets
The Company evaluates long-lived and intangible assets for potential impairment and records impairment losses when events and circumstances indicate the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts. Impairment losses are measured by comparing the fair value of the assets to their carrying amounts. In determining the need to record impairment charges, the Company is required to make certain estimates and assumptions regarding such things as the current fair market value of the assets and future net cash flows to be generated by the assets. If there are subsequent changes to these estimates or assumptions, or if actual results differ from these estimates or assumptions, such changes could impact the financial statements in the future. The Company conducted a qualitative impairment assessment of its long-lived and intangible assets and determined that no quantitative impairment tests were required to be performed as of June 30, 2022.
Income Taxes
Income Taxes
The Company utilizes the asset and liability method for accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based upon the estimated future tax effects of differences between the financial statement and tax basis of assets and liabilities, as measured by the current applicable tax rates. Deferred tax expense represents the result of changes in deferred tax assets and liabilities.
As required by the uncertain tax position guidance, the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would
more-likely-than-not
sustain the position following an audit. For tax positions meeting the
more-likely-than-not
threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company has applied the uncertain tax position guidance to all tax positions for which the statute of limitations remains open.
 
The Company is subject to federal, state and local income taxes in the United States and various states. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply.
The
Company is no longer subject to U.S. federal income tax examinations for the years prior to 2018. With a few exceptions, the Company is no longer subject to state or local income tax examinations for years prior to 2017. As of June 30, 2022, the Company had no outstanding tax examinations.
Concentration of Customer Risk
Concentration of Customer Risk
United is currently Air Wisconsin’s sole airline partner. Substantially all the Company’s revenues in the three and six months ended June 30, 2022 and 2021 were derived from the United capacity purchase agreement. For additional information, refer to Note 3,
Capacity Purchase Agreement with United
.
Estimates and Assumptions
Estimates and Assumptions
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Fair Value of Financial Instruments
Fair Value of Financial Instruments
The Company’s financial instruments include cash and cash equivalents, restricted cash, marketable securities, accounts receivable, long-term investments, accounts payable, and long-term debt. The Company believes the carrying amounts of these financial instruments, with the exception of marketable securities, are a reasonable estimate of their fair value because of the short-term nature of such instruments, or, in the case of long-term debt, because of interest rates available to the Company for similar obligations. Marketable securities are reported at fair value based on quoted market prices. Long-term investments are
held-to-maturity
debt securities and are reported at amortized cost.
Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date (that is, an exit price).
Fair Value Measurement
(Topic 820) establishes a three-tier fair value hierarchy, which prioritizes inputs used in fair value. The tiers are as follows:
Level 1—Quoted market prices in active markets for identical assets or liabilities.
Level 2—Inputs other than Level 1 inputs that are either directly or indirectly observable.
Level 3—Unobservable inputs developed using the Company’s estimates and assumptions, which reflect those that market participants would use.
The determination of where an asset or liability falls in the hierarchy requires significant judgment. The Company evaluates these determinations each reporting period, and it is possible that an asset or liability may be classified differently from year to year.
The tables below set forth the Company’s classification of marketable securities and long-term investments as of the periods presented:

Reclassifications
Reclassification
Certain operating expenses previously recorded in purchased services and other in the consolidated statements of operations in the amounts of $2,462 and $5,080, for the three and six months ended June 30, 2021, respectively, have been reclassified to aircraft maintenance, materials and repairs to

conform to the presentation for the three and six month periods ended June 30, 2022, with no effect on net income. The reclassification relates to certain third party maintenance activities.
Certain current liabilities previously recorded in contract liabilities in the consolidated balance sheets as of December 31, 2021 have been reclassified to deferred revenue to conform to the presentation as of June 30, 2022. As a result of this change, the consolidated statements of cash flows also required a reclassification from contract liabilities to deferred revenues in the
Cash Flows from Operating Activities
section of the consolidated statements of cash flows.
Upcoming Accounting Pronouncement
Upcoming Accounting Pronouncement
In June 2016, FASB issued ASU
2016-13,
Financial Instruments—Credit Losses
(Topic 326):
Measurement of Credit Losses on Financial Instruments
(ASU
2016-13).
ASU
2016-13
introduces a new accounting model known as Current Expected Credit Losses (CECL). CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. This model replaces the multiple existing impairment models in current GAAP, which generally require that a loss be incurred before it is recognized. The new standard will also apply to receivables arising from revenue transactions such as contract assets and accounts receivable. There are other provisions within the standard affecting how impairments of other financial assets may be recorded and presented, as well as expanded disclosures. ASU
2016-13
is effective for calendar years beginning after December 15, 2022, including interim periods within those calendar years, with early adoption permitted. The Company is currently evaluating the impact ASU
2016-13
will have on its consolidated financial statements.
