The following discussion and analysis of our financial condition and results of
operations should be read together with our audited consolidated financial
statements, accompanying notes, and other financial information included within
this Annual Report on Form
10-K
for the year ended December 31, 2021 (this "Annual Report"). The following
discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those expressed
or implied by the forward-looking statements below. Factors that could cause or
contribute to those differences in our actual results include, but are not
limited to, those discussed below and those discussed elsewhere within this
Annual Report, particularly in the sections entitled "Cautionary Note Regarding
Forward-Looking Statements" and "Risk Factors."

Overview

Harbor Diversified, Inc. ("Harbor") is a
non-operating
holding company that is the parent of a consolidated group of subsidiaries,
including AWAC Aviation, Inc. ("AWAC"), which is the sole member of Air
Wisconsin Airlines LLC ("Air Wisconsin"), a regional air carrier. Harbor is also
the direct parent of three other subsidiaries: (1) Lotus Aviation Leasing, LLC,
which leases flight equipment to Air Wisconsin, (2) Air Wisconsin Funding LLC,
which provides flight equipment financing to Air Wisconsin, and (3) Harbor
Therapeutics, Inc., which is a
non-operating
entity with no material assets. Because Harbor consolidates Air Wisconsin for
financial statement purposes, disclosures relating to activities of Air
Wisconsin also apply to Harbor, unless otherwise noted. When appropriate, Air
Wisconsin is named specifically for its individual contractual obligations and
related disclosures. Where reference is intended to include Harbor and its
consolidated subsidiaries, they may be jointly referred to as the "Company,"
"we," "us," or "our." Where reference is intended to refer only to Harbor
Diversified, Inc., it is referred to as "Harbor."

For the year ended December 31, 2021, Air Wisconsin operated a fleet of 64
CRJ-200
regional jets under a capacity purchase agreement (the "United capacity purchase
agreement") with its sole major airline partner, United Airlines, Inc.
("United"), with a presence at both Chicago O'Hare and Washington-Dulles, two of
United's key domestic hubs. All of Air Wisconsin's flights are operated as
United Express pursuant to the terms of the United capacity purchase agreement.
More than 99% of our operating revenues for the years ended December 31, 2021
and December 31, 2020 was derived from operations associated with the United
capacity purchase agreement.

Subject to certain limited exceptions, the United capacity purchase agreement
provides Air Wisconsin fixed daily revenue for each aircraft covered under the
agreement, a fixed payment for each departure and block hour flown, and
reimbursement of certain direct operating expenses in exchange for providing
regional flying service for United. The agreement also provides for the payment
or accrual of certain amounts by United to Air Wisconsin based on certain
scheduling benchmarks. The United capacity purchase agreement has the effect of
protecting Air Wisconsin, to an extent, from many of the elements that typically
cause volatility in airline financial performance, including fuel prices,
variations in ticket prices, and fluctuations in the number of passengers. In
providing regional flying under the United capacity purchase agreement, Air
Wisconsin uses United's logos, service marks, and aircraft paint schemes. United
controls route selection, pricing, seat inventories, marketing and scheduling.
In addition, United provides Air Wisconsin with ground support services and gate
access.

In October 2020, Air Wisconsin entered into an amendment to the United capacity
purchase agreement that, among other things, provided relief on certain
scheduling requirements and settled certain disputes that had existed between
United and Air Wisconsin over amounts owed to Air Wisconsin under the United
capacity purchase agreement. In April 2021, Air Wisconsin entered into a second
amendment to the United capacity purchase agreement which addressed the
scheduling of block hours after a certain date. Currently, a dispute exists
under the United capacity purchase agreement with respect to certain amounts
owed to Air Wisconsin by United. We cannot predict the outcome of this dispute
on the negotiation of an extension to the United capacity purchase agreement,
the execution of a new agreement with United, or our relationship with United
generally.

Impact of the
COVID-19
Pandemic on Our Business and Industry

As of the date of this filing, there continue to be widespread concerns
regarding the ongoing impacts and disruptions caused by the
COVID-19
pandemic in the regions in which Air Wisconsin operates. The extent to which the
COVID-19
pandemic will impact our industry, business, financial condition, and results of
operations in the future is highly uncertain and will be affected by a number of
factors. These include the duration and extent of the
COVID-19
pandemic, the development of new variants of the
COVID-19
virus that may be more contagious or virulent than prior versions, the scope and
effect of vaccine mandates and of other mandated or recommended containment and
mitigation measures, the effect of government stabilization and recovery
efforts, and the success of vaccine distribution programs.

Focus on Safety for Employees and Passengers



The safety and well-being of our employees and passengers are our priority.
Throughout the
COVID-19
pandemic, Air Wisconsin has taken numerous steps to provide its employees and
passengers with the ability to take appropriate safety measures in accordance
with guidelines provided by the Centers for Disease Control and Prevention,
including working with United to:

• enhance Air Wisconsin's aircraft cleaning and sanitation procedures;





     •    provide gloves, masks, and other personal protective equipment for crew
          members;



  •   provide options to Air Wisconsin's employees who are diagnosed with
      COVID-19,
      including pay protection and extended leave options;


• provide financial incentive to employees to encourage vaccination and


          booster shots;



     •    implement workforce social distancing, mask requirements and other
          protection measures, and enhanced cleaning of our facilities; and



  •   provide regular, ongoing communication regarding impacts of the
      COVID-19
      pandemic, including health and safety protocols and procedures.

Reduction in Demand for Air Travel



Public concerns about the
COVID-19
virus, as well as the various governmental guidelines and restrictions adopted
to limit the spread of the virus, have had a material adverse impact on
passenger demand for air travel since the beginning of the pandemic. While
passenger demand for air travel has generally increased in recent months as a
result of the easing of certain of these guidelines and restrictions, as well as
expanded availability and adoption of vaccines, United has stated that it
expects demand will remain below
pre-pandemic
levels throughout 2022.

Notwithstanding the significant negative impact to our business and the airline
industry, Air Wisconsin's receipt of governmental assistance under the SBA Loan
and the Payroll Support Program (each as described below), has mitigated to some
extent the adverse impacts of the
COVID-19
pandemic.

Labor Shortages

Historically, the airline industry has experienced periodic shortages of
qualified personnel, particularly pilots and mechanics. As a result of the
reduced flying caused by the
COVID-19
pandemic, the shortage was temporarily abated. However, as flight demand
increased, the shortage has become acute, particularly for regional airlines
such as Air Wisconsin due to a number of factors, including retirements and
employees seeking opportunities at mainline carriers and in other industries.
Air Wisconsin's monthly departures and scheduled block hours generally increased
from June 2020 until October 2021. However, departures and scheduled block hours
rarely reached
pre-pandemic
levels and have declined slightly since October 2021, mostly as a result of
pilot shortages.

Impact on Competitive Environment



Several regional and larger carriers have ceased operations as a direct or
indirect result of the
COVID-19
pandemic. As of the date of this filing, ExpressJet Airlines, Inc., Miami Air
International, Trans States Airlines, and Compass Airlines, each of which are
domestic, regional, or charter airlines, have either filed for Chapter 11 or
Chapter 7 bankruptcy, or ceased or severely limited operations. The impact of
these and other changes to the competitive environment on our business and
industry is highly uncertain.

Operational Challenges



During the early stages of the
COVID-19
pandemic, Air Wisconsin's scheduled departures and block hours were
significantly reduced. As flight demand increased, Air Wisconsin's scheduled
departures and block hours increased significantly through October 2021.
However, the effects of the
COVID-19
pandemic, the industry wide pilot and mechanic shortages, and the significant
increase in scheduled departures and block hours increased Air Wisconsin's costs
and negatively affected its operations in the second half of 2021 in several
respects:

Air Wisconsin had to cancel certain flights due to staffing issues, which


          is consistent with trends experienced across the airline industry;



     •    the cost of certain maintenance activities increased as a result of

          supply chain issues;


Air Wisconsin experienced delays and increased cost in obtaining third


          party maintenance services;


• aircraft maintenance and repair costs, as well as payroll costs,


          increased as a result of increased flying levels across our industry;



     •    one of Air Wisconsin's maintenance bases was closed for six days as a

result of an outbreak of

COVID-19,

which required moving aircraft to different maintenance bases and the use


          of third-party maintenance providers;


• certain changes in the flight schedules that United assigned to Air

Wisconsin resulted in insufficient utilization of Air Wisconsin's

maintenance bases, which led to increases in Air Wisconsin's expenses;


          and



     •    these operational and performance issues negatively impacted the

incentive payments Air Wisconsin received under the United capacity

purchase agreement and in some cases required the payment of penalties.




Paycheck Protection Program

In April 2020, Air Wisconsin received a $10.0 million loan ("SBA Loan") under
the small business Paycheck Protection Program ("PPP") established under the
Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and
administered by the Small Business Administration ("SBA"). The loan was
forgivable subject to certain limitations, including that the loan proceeds be
used to retain workers and for payroll, mortgage payments, lease payments, and
utility payments. The entire principal amount and accrued interest were forgiven
in August 2021 in the amount of $10.1 million, which was recorded as gain on
extinguishment of debt in the consolidated statements of operations.

Payroll Support Program



In April 2020, Air Wisconsin entered into a Payroll Support Program Agreement
("PSP-1
Agreement") with respect to payroll support ("Treasury Payroll Support") from
the U.S. Department of the Treasury ("Treasury") under a program ("Payroll
Support Program") provided by the CARES Act. Pursuant to the Payroll Support
Program, Air Wisconsin received approximately $42.2 million, all of which was
received in the year ended December 31, 2020. The Treasury commenced a routine
audit of Air Wisconsin's compliance with the terms of the
PSP-1
Agreement. As of the date of this filing, Air Wisconsin has not received written
confirmation from the OIG regarding the status or results of the audit.

In December 2020, the federal Consolidated Appropriations Act of 2021 ("PSP
Extension Law") was adopted, which provided for additional payroll support to
eligible air carriers. In March 2021, pursuant to the PSP Extension Law, Air
Wisconsin entered into a Payroll Support Program Extension Agreement with the
Treasury (the
"PSP-2
Agreement"), which is substantially similar to the
PSP-1
Agreement. Air Wisconsin received approximately $33.0 million pursuant to the
PSP-2
Agreement, all of which was received in the six months ended June 30, 2021.

In March 2021, the federal American Rescue Plan Act of 2021 ("American Rescue
Plan") was adopted, which provided further payroll support to eligible air
carriers. In June 2021, pursuant to the American Rescue Plan, the Treasury
entered into a Payroll Support Program 3 Agreement with Air Wisconsin (the
"PSP-3
Agreement" and, together with the
PSP-1
Agreement and the
PSP-2
Agreement, the "PSP Agreements"), which is substantially similar to the
PSP-1
Agreement and the
PSP-2
Agreement. Air Wisconsin received approximately $33.3 million pursuant to the
PSP-3
Agreement, all of which was received in the six months ended September 30, 2021.

                                       34

--------------------------------------------------------------------------------

Table of Contents



The PSP Agreements contain various covenants, including that (i) the payroll
support proceeds must be used exclusively for the payment of wages, salaries,
and benefits, (ii) Air Wisconsin cannot involuntarily terminate or furlough any
employee or reduce any employee's pay rates or benefits without that employee's
consent, in any case prior to certain dates, (iii) Air Wisconsin cannot pay
total compensation to certain employees in excess of certain total compensation
caps, (iv) Air Wisconsin cannot pay dividends or make other capital
distributions prior to certain dates, and (v) neither Air Wisconsin nor any of
its affiliates can purchase an equity security of Air Wisconsin, or any direct
or indirect parent company of Air Wisconsin, that is listed on a national
securities exchange prior to certain dates. If Air Wisconsin fails to comply
with its obligations under these agreements, it may be required to repay some or
all of the funds provided to it under these agreements. Any such default,
acceleration, insolvency or failure to comply would likely have a material
adverse effect on our business.

For additional information, refer to Note 8,
Commitments and Contingencies,
in our audited consolidated financial statements within this Annual Report.

Employee Retention Credit

Air Wisconsin received an employee retention credit of approximately $1.1 million in 2021 pursuant to the CARES Act for payroll expenses incurred in 2020.



2021 Financial Highlights

For the year ended December 31, 2021, we had total operating revenues of
$247.6 million, a 33.1% increase, compared to $185.9 million for the year ended
December 31, 2020. Net income for the year ended December 31, 2021 was
$92.6 million, or net income of $1.69 per basic share and $1.29 per diluted
share, compared to net income of $39.8 million, or $0.71 per basic share and
$0.56 per diluted share, for the year ended December 31, 2020. For additional
information, refer to Note 12,
Earnings per Share and Equity
, and Note 13,
Stock Options
, in our audited consolidated financial statements included in this Annual
Report.

Revenue



The number of aircraft we have in scheduled service and the block hours and
departures we generate from our flights are primary drivers of our revenues
under the United capacity purchase agreement. As a result of greater passenger
demand since the beginning stages of the
COVID-19
pandemic, block hours increased from 74,438 during the year ended December 31,
2020 to 116,081 during the year ended December 31, 2021, or by 55.9%, and our
number of departures increased from 52,405 in 2020 to 80,927 in 2021, or by
54.4%.

Primarily as a result of the increased flight schedules during the year ended
December 31, 2021 compared to the year ended December 31, 2020, revenues from
the United capacity purchase agreement increased by 33.2% to $247.5 million.
Furthermore, we deferred recognizing revenue of $1.6 million related to fixed
payments received under the United capacity purchase agreement during the year
ended December 31, 2021, compared to $43.2 million during the year ended
December 31, 2020, consistent with recognizing this revenue based on current and
estimated future departures. For additional information, refer to the section
entitled "Critical Accounting Policies -
Revenue Recognition
." However, as a result of the October 2020 amendment to the United capacity
purchase agreement, we recognized $17.1 million of revenue during the year ended
December 31, 2021 as compared to $28.7 million of revenue during the year ended
December 31, 2020, resulting from the payment or accrual by United to Air
Wisconsin based on certain scheduling benchmarks and the settlement of certain
other outstanding items. For additional information, refer to Note 1, Summary of
Significant Accounting Policies -
Contract Revenues
, in our audited consolidated financial statements included in this Annual
Report.

Operating Expenses



Our total operating expenses decreased $0.2 million, or 0.1%, for the year ended
December 31, 2021 compared to the year ended December 31, 2020. Although our
year over year operating expenses were relatively unchanged, the increased
number of flights we operated as a result of the increase in passenger demand
since the beginning stages of the
COVID-19
pandemic resulted in a $16.4 million increase in aircraft maintenance and repair
costs and a $7.8 million increase in payroll expense, partially offset by a
$6.6 million decrease in aircraft rent due to the acquisition of formerly leased
aircraft in 2020. Furthermore, we recorded an additional $24.1 million in
payroll support grants received from the Treasury as an offset to our operating
expenses during the year ended December 31, 2021 compared to the year ended
December 31, 2020. For additional information, refer to the section entitled "-
Results of Operations-Operating Expenses
."

Stock Repurchase Program



Harbor's board of directors has adopted a stock repurchase program pursuant to
which Harbor could initially repurchase up to $1.0 million of shares of its
common stock during the first calendar month of the program, subject to an
automatic increase of $1.0 million per calendar month thereafter. The number of
shares to be repurchased, and the timing of any such repurchases, depend on a
number of factors, including the trading price of the common stock, the
Company's financial performance and liquidity position, general market
conditions, applicable legal requirements and other factors. Repurchases may be
affected through open market transactions, privately negotiated transactions, or
any other lawful means. Harbor may, but is not required to, effect repurchases
under a trading plan adopted pursuant to Rule
10b5-1
under the Exchange Act, or subject to Rule
10b-18
under the Exchange Act. Harbor is not obligated under the program to acquire any
particular number or value of shares and can suspend or terminate the program at
any time. Harbor acquired 1,547,006 shares of its common stock pursuant to the
stock repurchase program during the year ended December 31, 2021.

Economic Conditions, Challenges and Risks Impacting Financial Results



Although the United capacity purchase agreement reduces Air Wisconsin's exposure
to certain risks, its operating and business performance is driven by various
factors that typically affect regional airlines and their markets, including
factors that affect the broader airline and travel industries. The following key
factors, in addition to the impact of the
COVID-19
pandemic, may materially affect our future performance.

Extension of United Capacity Purchase Agreement
. The United capacity purchase agreement expires in February 2023. Air Wisconsin
and United are in active negotiations regarding the extension of the agreement
or the execution of a new agreement, although we can provide no assurance that
any agreement will be reached. Accordingly, Air Wisconsin is exploring a
commercial agreement with another major airline partner, as well as other
business strategies to take advantage of anticipated demand for regional air
services.

Contract Dispute
. More than 99% of our operating revenues for the year ended December 31, 2021
were derived from operations associated with the United capacity purchase
agreement. Agreements such as the United capacity purchase agreement are subject
to interpretation, and disputes may arise if the parties apply different
interpretations to the agreements. Currently, a dispute exists under the United
capacity purchase agreement with respect to certain amounts owed to Air
Wisconsin by United. We cannot predict the outcome of this dispute.

Industry Volatility
. The airline industry is volatile and affected by numerous factors, such as
tourist activity, consumer confidence, discretionary spending, fare initiatives,
fuel prices, labor actions, global pandemics, outbreak of war or hostilities,
changes in governmental regulations, government sanctions, changes in taxes and
fees, and weather. These factors have contributed to a number of
reorganizations, bankruptcies, liquidations and business combinations among
major and regional airlines. Historically, capacity purchase agreements shelter
regional airlines from some of these factors.

Competition


.
The airline industry is highly competitive. Air Wisconsin competes principally
with other regional airlines. We believe that major airlines typically award
capacity purchase agreements to regional airlines based on the following
criteria: aircraft fleet type; ability to fly proposed schedules; availability
of labor resources, including pilots; proposed economic terms; aircraft and
engine resources; financial resources; operational reliability; reputation;
customer service levels; and other factors. The extension of the United capacity
purchase agreement, the execution of a new agreement with United, or the pursuit
of a commercial agreement with another major airline partner will depend, in
significant part, on Air Wisconsin's ability to maintain a cost structure
competitive with other regional air carriers, attract and retain qualified
pilots, and maintain operational reliability. However, we continue to believe
there will be strong demand from major airlines for regional air services, and
we seek to continue to position Air Wisconsin to take advantage of this
anticipated demand.

Maintenance Contracts, Costs and Timing
.
Air Wisconsin's employees perform routine airframe and engine maintenance along
with periodic inspections of equipment at its maintenance facilities. It also
uses third-party vendors for certain heavy airframe and engine maintenance work,
along with parts procurement and component overhaul services for Air Wisconsin's
aircraft. As of December 31, 2021, the average age of Air Wisconsin's
CRJ-200
regional jets was approximately 19.3 years. We expect that maintenance costs
will increase as its fleet continues to age. We use the direct expense method of
accounting for Air Wisconsin's maintenance of airframes, rotable parts, and
normal recurring maintenance and for Lotus' maintenance of engines, pursuant to
which we recognize the expense when the maintenance work is completed. We use
the deferral method of accounting for Air Wisconsin's planned major maintenance
activities for engines pursuant to which the capitalized engine overhaul costs
are amortized over the estimated useful life measured in engine cycles remaining
until the next scheduled shop visit. While Air Wisconsin keeps a record of
expected maintenance events, the actual timing and costs of maintenance expense
are subject to variables, such as estimated usage, government regulations and
the level of unscheduled maintenance events and their actual costs.

Aircraft Leases
. During the year ended December 31, 2020, in three different transactions, Air
Wisconsin acquired all thirteen of the remaining operational aircraft that were
under various lease agreements.

Labor


.
The airline industry is heavily unionized. The wages, benefits and work rules of
unionized airline industry employees are determined by collective bargaining
agreements. As of December 31, 2021, Air Wisconsin had 1,212 full-time employees
and 36 part-time employees, for a total of 1,248 employees, of which 995 were
represented by unions. Air Wisconsin's collective bargaining agreement with its
pilots, represented by the Airline Pilots Association, is amendable in November
2022 and its collective bargaining agreement with its flight attendants,
represented by the Association of Flight Attendants-CWA, is amendable in October
2022. Air Wisconsin's collective bargaining agreement with its dispatchers
represented by the Transport Workers Union of America, is amendable and is in
mediated negotiations. Conflicts between airlines and their unions can lead to
work slowdowns or stoppages. A strike or other significant labor dispute with
Air Wisconsin's unionized employees may adversely affect Air Wisconsin's ability
to conduct business.

Availability and Training of Qualified Pilots
. On July 8, 2013, as directed by the U.S. Congress, the FAA issued more
stringent pilot qualification and crew member flight training standards, which,
among other things, increased the required training time for new airline pilots
from 250 hours to 1,500 hours of flight time. These changes dramatically reduced
the supply of qualified pilot candidates eligible for hiring by the airline
industry and, in response, regional airlines implemented significant pilot wage
and bonus increases. In recent years, Air Wisconsin experienced a significant
increase in pilot attrition, and our results of operations may be negatively
impacted if Air Wisconsin is unable to hire and train pilots in a timely manner.

Refer to the section entitled "
Risk Factors
" within this Annual Report for a discussion of the general and specific factors
and trends affecting our business and results of operations.

Seasonality



Our results of operations for any interim period are not necessarily indicative
of those for the entire year because the airline industry is subject to seasonal
fluctuations and general economic conditions. While Air Wisconsin's operations
can be negatively impacted by factors outside of its control, including
inclement weather, the United capacity purchase agreement mitigates some of the
risks associated with seasonal fluctuations.

Components of Our Results of Operations

The following discussion summarizes the key components of our consolidated statements of operations.


                                       37

--------------------------------------------------------------------------------

Table of Contents

Operating Revenues

Our consolidated operating revenues consist primarily of contract revenues from flight services.



Contract Revenues
. Contract revenues consist of the fixed monthly amounts per aircraft received
pursuant to the United capacity purchase agreement, along with the additional
amounts received based on the number of departures and block hours flown. The
United capacity purchase agreement includes provisional cash payments four times
per month based on a projected level of flying each month. Air Wisconsin and
United subsequently reconcile these payments to the actual completed flight
activity on a monthly basis. In addition, contract revenues in 2021 and 2020
include the impact of the amendment to the United capacity purchase agreement
that Air Wisconsin entered into in October 2020 which, among other things,
provides for the payment or accrual of certain amounts by United to Air
Wisconsin based on certain scheduling benchmarks. The accruals are evidenced by
notes receivable from United to Air Wisconsin.

Contract Services and Other
.
Contract services and other revenue are not material and primarily consist of
the sale of parts.

Operating Expenses

Our consolidated operating expenses consist of the following items:



Payroll and Related Costs
.
Payroll and related costs primarily relate to wages, benefits and payroll taxes
for all Air Wisconsin's employees, as well as costs related to lodging of our
flight crews and crew training expenses.

Aircraft Fuel and Oil
. Substantially all aircraft fuel and related fueling costs for flying under the
United capacity purchase agreement are directly paid and supplied by United; we
do not record any revenue or expense for such fuel. We include the cost of
aircraft oil, which we are responsible for under the United capacity purchase
agreement, although that expense is not material.

Aircraft Maintenance, Materials and Repairs
.
Aircraft maintenance, materials and repairs include costs related to airframe
and rotable overhauls, normal recurring maintenance and the cost of aircraft
materials and parts related to Air Wisconsin's
CRJ-200
regional jets and the cost of engine maintenance by Lotus. With the exception of
engine overhauls by Air Wisconsin, we record these costs using the direct
expense method of accounting, pursuant to which the expense is recognized when
the maintenance work is completed. As a result of using the direct expense
method, the timing of maintenance expense reflected in the financial statements
may vary from period to period. We capitalize Air Wisconsin's engine overhaul
costs, and the amortization expense is included in aircraft maintenance,
materials and repairs using the deferral method of accounting; Air Wisconsin's
engine overhaul costs are amortized over the estimated useful life of the
overhaul measured in engine cycles remaining until the next scheduled shop
visit.

Aircraft Rent
.
Aircraft rent includes costs related to leased aircraft, including any lease
termination expenses related to aircraft acquired prior to the end of their
lease term.

Other Rents
.
Other rents include expenses related to leased engines, costs related to leased
flight simulators used to train Air Wisconsin's pilots, and building rents such
as crew and maintenance bases and corporate office space.

Depreciation, Amortization and Obsolescence
.
Depreciation expense is a periodic
non-cash
charge primarily related to aircraft, engine and rotable parts depreciation.
Obsolescence expense is a periodic
non-cash
charge primarily related to the provision for obsolescence on our expendable
aircraft parts.

Purchased Services and Other
.
Purchased services and other expense primarily includes third-party aircraft
line maintenance support in Chicago (O'Hare) and Washington (Dulles),
information technology systems, legal fees, professional and technical fees,
insurance and property taxes and other administrative expenses. The majority of
insurance and property taxes are pass-through costs to United.

Segment Reporting



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 in deciding how to allocate resources and in
assessing operating performance. In consideration of Accounting Standards
Codification (ASC) 280, "
Segment Reporting,
" we are not organized around specific services or geographic regions. We
currently operate in one service line providing scheduled flight services in
accordance with the United capacity purchase agreement. Additionally, our chief
operating decision maker uses consolidated financial information to evaluate our
performance, which is the same basis upon which the results and performance of
the Company are communicated to the board of directors. The chief operating
decision maker bases all significant decisions regarding the allocation of our
resources on a consolidated basis. Based on the information described above and
in accordance with the applicable literature, management has concluded that we
are organized and operate as one operating and reportable segment.

The increase in departures and RPMs during the year ended December 31, 2021,
compared to the year ended December 31, 2020, was primarily due to an increase
in flying under the United capacity purchase agreement. As a result of the
increased demand for air travel since the beginning stages of the
COVID-19
pandemic, total operating revenues increased by $61.6 million, or 33.1%, during
the year ended December 31, 2021, compared to the year ended December 31, 2020.
Air Wisconsin's block hours flown during the year ended December 31, 2021
increased 55.9%, compared to the year ended December 31, 2020.

Payroll and Related Costs
. Payroll and related costs increased $7.8 million, or 7.9%, to $106.9 million
for the year ended December 31, 2021, compared to the year ended December 31,
2020. The increase was primarily driven by an increase in crew wages, bonuses
and training expenses of $8.8 million and personnel expenses of $3.0 million.
These increases were offset by other wages, taxes and benefits which decreased
by $2.6 million, inclusive of a refund claim for the employee retention credit
in the amount of $1.1 million, and a decrease in management wages of
$1.1 million.

Aircraft Fuel and Oil
. Substantially all of the fuel costs incurred as a result of flying pursuant to
the United capacity purchase agreement during the years ended December 31, 2021
and 2020 were directly paid to suppliers by United. Aircraft fuel and oil
expense primarily reflects the costs associated with aircraft oil purchases.
This increase was primarily due to an increase in the number of flights we
operated.

Aircraft Maintenance, Materials and Repairs
. Aircraft maintenance, materials and repairs costs increased $16.4 million, or
59.9%, to $43.7 million for the year ended December 31, 2021, compared to the
year ended December 31, 2020. This increase was primarily driven by an increase
in required maintenance and repair activities due to an increase in flying
attributable to increased passenger demand for air transportation.

Aircraft Rent
. Aircraft rent expense decreased $6.6 million, or 99.0%, to $0.07 million for
the year ended December 31, 2021, compared to the year ended December 31, 2020.
The decrease was due to Air Wisconsin's acquisition of its remaining operating
leased aircraft during 2020. Air Wisconsin incurred $0.07 million in aircraft
rent expense in 2021 for a
CRJ-700
that was leased for the purpose of adding that aircraft type to its FAA
Operations Specifications. For additional information, refer to Note 4,
Property and Equipment
, in our audited consolidated financial statements included in this Annual
Report.

Other Rents
. Other rents expense increased $0.8 million, or 17.4%, to $5.4 million for the
year ended December 31, 2021, compared to the year ended December 31, 2020. The
increase was primarily due to an increase of $0.8 million in flight training
simulator rental expense.

Depreciation, Amortization and Obsolescence
. Depreciation, amortization and obsolescence expense decreased $0.7 million, or
2.5%, to $26.6 million for the year ended December 31, 2021, compared to the
year ended December 31, 2020. The decrease was primarily due to the retirement
of leasehold improvements in 2020 on formerly leased aircraft and the retirement
of a spare engine. For additional information, refer to Note 4,
Property and Equipment
, in our audited consolidated financial statements included in this Annual
Report.

Payroll Support Program
. The proceeds of the Treasury Payroll Support received pursuant to the PSP
Agreements are recorded in cash and cash equivalents when received and were
recognized as a reduction in expense over the periods that the funds are
intended to offset payroll expenses. For the years ended December 31, 2021, and
December 31, 2020, Air Wisconsin received and recognized approximately
$66.3 million and $42.2 million, respectively, under the Payroll Support
Program.

Purchased Services and Other
. Purchased services and other expense increased $6.2 million, or 31.2%, to
$25.9 million for the year ended December 31, 2021, compared to the year ended
December 31, 2020. This increase was primarily due to an increase in outside
services, consisting primarily of aircraft line and on call maintenance, of
$6.0 million, an increase in insurance expense of $1.1 million, an increase in
supplies of $0.5 million, and an increase of $0.4 million of other credits,
partially offset by a decrease in legal expense of $0.5 million, a decrease in
professional and technical fees, consisting primarily of consulting and auditing
services of $0.3 million, and a decrease in property tax expense of
$0.3 million. The year ended December 31, 2021 included a net gain on disposal
of assets of $0.3 million compared to a net loss of $0.4 million on disposal of
assets in the year ended December 31, 2020.

Other Income (Expense)



Interest Income
. Interest income increased $1.4 million for the year ended December 31, 2021,
compared to the year ended December 31, 2020. The increase was primarily due to
an increase in interest earned on the long-term notes receivable due from
United.

Interest Expense
. Interest expense decreased by $0.9 million for the year ended December 31,
2021, compared to the year ended December 31, 2020, primarily due to the
significant prepayment of debt in 2021. For additional information, refer to the
section entitled "
- Debt and Credit Facilities
" and Note 6,
Debt
, in our audited consolidated financial statements included in this Annual
Report.

Loss on Marketable Securities
.
Loss on marketable securities was $1.2 million for the year ended December 31,
2021. The loss reflects the change in market value and sales of securities for
the year ended December 31, 2021. There were no marketable securities held
during the year ended December 31, 2020.

Gain on Extinguishment of Debt.
Gain on extinguishment of debt was $10.4 million for the year ended December 31,
2021. A gain of $10.1 million resulted from the forgiveness of the SBA Loan with
the remainder attributable to the prepayment of debt. For additional information
refer to Note 6,
Debt
, in our audited consolidated financial statements included in this Annual
Report.

Other, Net
. Other income increased by $2.5 million for the year ended December 31, 2021,
compared to the year ended December 31, 2020. This increase primarily consists
of dividend income of $2.5 million from investments in marketable securities.

Net Income



Net income for the year ended December 31, 2021 was $92.6 million, or $1.69 per
basic share and $1.29 per diluted share, compared to net income of
$39.8 million, or $0.71 per basic share and $0.56 per diluted share for the year
ended December 31, 2020. For additional information, refer to Note 12,
Earnings per Share and Equity
, in our consolidated financial statements included in this Annual Report.

The increase in net income for the year ended December 31, 2021 primarily
resulted from increased revenues as a result of increased demand for air travel
and slightly overall lower operating expenses, as a result of the increase in
the contra-expense related to funds received under the Payroll Support Program,
and the gain resulting from the forgiveness of the SBA Loan. Although overall
operating expenses were slightly lower in the year ended December 31, 2021 when
compared to the year ended December 31, 2020, there were significant increases
in aircraft maintenance and repair costs as well as payroll and related costs
resulting from the increased flying levels.

Income Taxes



In the year ended December 31, 2021, our effective tax rate was 21.5%, compared
to 5.8% in the year ended December 31, 2020. Our tax rate can vary depending on
changes in tax laws, adoption of accounting standards, the amount of income we
earn in each state and the state tax rate applicable to such income, as well as
any valuation allowance required on our deferred tax assets.

We recorded an income tax provision of $25.4 million and $2.5 million for the years ended December 31, 2021 and 2020, respectively.



The income tax provision for the year ended December 31, 2021 resulted in an
effective tax rate of 21.5%, which differed from the U.S. federal statutory rate
of 21%, primarily due to the impact of state taxes and permanent differences
between financial statement and taxable income. In addition to the state
effective tax rate impact, other state impacts include changes in state
apportionment and statutory rates.

The income tax provision for the year ended December 31, 2020 resulted in an
effective tax rate of 5.8%, which differed from the U.S. federal statutory rate
of 21% primarily due to the impact of state taxes, permanent differences between
financial statement and taxable income and changes in federal and state
valuation allowances against deferred tax assets. In addition to the state
effective tax rate impact, other state impacts include changes in state
apportionment and statutory rates.

As of December 31, 2021, we did not have a federal net operating loss carryforward. Our state net operating loss carryforward was approximately $0.7 million. The state net operating losses expire beginning in 2024, with some states having either longer expiration periods or none at all.



For additional information, refer to Note 5,
Income Taxes
, in our audited consolidated financial statements included in this Annual
Report.

Liquidity and Capital Resources



Although Air Wisconsin's departures and block hours generally increased through
the year ended December 31, 2021 and the date of this filing, the
COVID-19
pandemic continues to evolve. As such, the ongoing impact that the pandemic will
have on our financial condition, results of operations, and liquidity remains
highly uncertain. Management is actively monitoring the impact on our
operations, airline partner, suppliers, industry, and workforce. We are taking
actions based on currently available information to address the changing
business environment; however, we cannot predict what changes in circumstances
and future developments may occur or what effect those changes or developments
may have on our business.

Sources and Uses of Cash

Our principal sources of liquidity are our cash and cash equivalents balance,
our marketable securities, Air Wisconsin's cash flows from operations, and its
receipt of governmental assistance under the SBA Loan and the Payroll Support
Program. As of December 31, 2021, our cash and cash equivalents balance was
$37.2 million and we held $138.4 million of marketable securities. For the year
ended December 31, 2021, we generated cash flows from operations of
$94.2 million, which included $66.3 million received pursuant to the Payroll
Support Program. In the near term, Air Wisconsin expects to fund its liquidity
requirements through cash generated from operations and existing cash, cash
equivalents, and marketable securities balances.

Air Wisconsin requires cash to fund its operating expenses and working capital
requirements, which include outlays for capital expenditures, labor,
maintenance, and payment of debt service obligations, including principal and
interest payments. Our cash needs vary from period to period, based in part on
the timing and costs of significant maintenance events and increased labor costs
due to shortages of qualified pilots and mechanics.

                                       42

--------------------------------------------------------------------------------

Table of Contents



During the ordinary course of business, we evaluate our cash requirements and,
if necessary, adjust operating and capital expenditures to reflect current
market conditions and our projected demand. Our capital expenditures are
typically used to acquire or maintain aircraft and flight equipment for Air
Wisconsin. During the year ended December 31, 2021, we paid $3.6 million in
capital expenditures primarily related to purchases of rotable parts and
capitalized engine overhauls. Future capital expenditures may be impacted by
events and transactions that are not currently forecasted.

Air Wisconsin's ability to service its long-term debt obligations and business
development efforts depends on its ability to generate cash from operating
activities, which is subject to, among other things, its future operating
performance, as well as other factors, some of which may be beyond our control.
If Air Wisconsin fails to generate sufficient cash from operations, it may need
to obtain additional debt financing, or restructure its current debt financing,
to achieve its longer-term objectives. As of December 31, 2021, Harbor had no
indebtedness, and Air Wisconsin had $67.6 million in secured indebtedness,
including $5.9 million of short-term indebtedness and $61.7 million of long-term
indebtedness, all of which is secured indebtedness incurred in connection with
the Aircraft Notes. For additional information, refer to the section entitled "
- Debt and Credit Facilities
" and Note 6,
Debt
, in our audited consolidated financial statements included in this Annual
Report.

The United capacity purchase agreement and Air Wisconsin's credit agreements
with its lender contain restrictions that limit Air Wisconsin's ability to pay,
or prohibit it from paying, dividends or distributions to Harbor. In addition,
the PSP Agreements prevent Air Wisconsin from paying dividends prior to certain
dates.

We believe our available working capital and anticipated cash flows from
operations will be sufficient to meet our liquidity requirements for at least
the next 12 months from the date of this filing. To the extent that results or
events differ from our financial projections or business plans, our liquidity
may be adversely impacted.

Restricted Cash

As of December 31, 2021, in addition to cash and cash equivalents of
$37.2 million, the Company had $1.4 million in restricted cash which primarily
relates to a credit facility used for the issuance of cash collateralized
letters of credit supporting Air Wisconsin's performance of its obligations
under certain lease agreements, airport agreements and insurance policies, as
well as cash held for the repurchase of shares under Harbor's stock repurchase
program. Restricted cash includes amounts escrowed in an interest-bearing
account that secure the credit facility.

Net Cash Flows Provided by Operating Activities



During the year ended December 31, 2021, our net cash flows provided by
operating activities were $94.2 million. We had net income of $92.6 million,
which was primarily due to increased revenues as a result of the increase in
demand for air travel, and slightly lower overall expenses when compared to the
year ended December 31, 2020, which was due in part to payroll support received
under the Payroll Support Program. Net cash flows are further adjusted for
increases in cash primarily related to depreciation, obsolescence and
amortization of $24.9 million, contract liabilities of $22.6 million, and
accounts payable of $8.3 million, partially offset by decreases in cash
primarily related to the gain on extinguishment of debt of $10.4 million,
long-term deferred revenues of $21.7 million, notes receivable of $15.1 million,
and $6.0 million of deferred income taxes.

During the year ended December 31, 2020, our net cash flows provided by
operating activities was $73.2 million. We had net income of $39.8 million,
which was primarily due to lower expenses as a result of payroll support
received under the PSP Agreements, and lower expenses related to reduced flying
activity, further adjusted for increases in cash primarily related to long-term
deferred revenue of $30.7 million under the United capacity purchase agreement,
depreciation and engine overhaul amortization of $28.5 million, $2.5 million
related to operating lease
right-of-use
assets, contract liabilities of $12.3 million and deferred income taxes of
$3.6 million, partially offset by decreases in cash primarily related to notes
receivable of $32.4 million, accounts payable of $7.8 million, amortization of
contract costs of $2.5 million, prepaid expenses of $1.9 million and accounts
receivable of $2.4 million.

Net Cash Flows Used in Investing Activities

During the year ended December 31, 2021, our net cash used in investing activities was $143.1 million resulting primarily from investments in marketable securities.



During the year ended December 31, 2020, our net cash flow used in investing
activities was $8.7 million resulting primarily from the purchase of aircraft
and an investment in rotable parts and engine overhauls to support Air
Wisconsin's fleet under the United capacity purchase agreement.

Net Cash Flows Used in Financing Activities

During the year ended December 31, 2021, our net cash used in financing activities was $43.7 million, reflecting $40.1 million in repayments of long-term debt, $0.8 million of dividends paid on the Series C Preferred, and $2.8 million to repurchase shares of our common stock.

During the year ended December 31, 2020, our net cash used in financing activities was $3.6 million, reflecting Air Wisconsin's receipt of a $10.0 million loan under the PPP established pursuant to the CARES Act, partially offset by a dividend payment of $0.8 million on the Series C Preferred and payments of long-term debt of $12.8 million.

Commitments and Contractual Obligations



In June 2021, Air Wisconsin prepaid approximately $11.2 million of debt
outstanding under the Aircraft Notes due December 31, 2025, and approximately
$17.0 million of the principal amount outstanding under a credit agreement due
2022 along with all interest due as of June 30, 2021. The prepayment under the
Aircraft Notes resulted in a $0.2 million gain on extinguishment of debt due to
the decrease in previously expected future undiscounted cash flows used in
determining the carrying value of the debt.

In August 2021, the SBA granted forgiveness of the $10.0 million SBA Loan. The accrued interest in the amount of $0.1 million was also forgiven. The forgiveness resulted in a $10.1 million gain on extinguishment of debt.

In September 2021, Air Wisconsin prepaid the remaining amount due under the credit agreement due 2022 in the amount of $10.0 million along with interest of $0.1 million.



As of December 31, 2021, Air Wisconsin had $86.1 million of long-term debt
(including principal and projected interest obligations) and operating lease
obligations (including current maturities). This amount consisted of
$59.5 million in long-term notes payable related to owned aircraft used in
continuing operations. As of December 31, 2021, Air Wisconsin also had
$18.6 million of operating lease obligations primarily related to certain
training simulators and facilities. Air Wisconsin's debt obligations set forth
below include an aggregate of $8.1 million in projected interest costs through
2026 and thereafter.

excess cash flow. The amounts set forth in the table do not reflect any such
additional excess cash flow payments. As a result of certain prepayments made
under the Aircraft Notes in June 2021, no semi-annual installments are due prior
to December 31, 2022. As of December 31, 2021, all of Air Wisconsin's long-term
debt was subject to fixed interest rates. For additional information regarding
the Aircraft Notes and Other Loans, refer to Note 6,

Series C Convertible Redeemable Preferred Stock



In January 2020, Harbor completed an acquisition from Southshore Aircraft
Holdings, LLC and its affiliated entities ("Southshore") of three
CRJ-200
regional jets, each having two General Electric ("GE") engines, plus five
additional GE engines, in exchange for the issuance of 4,000,000 shares of
Harbor's Series C Convertible Redeemable Preferred Stock (the "Series C
Preferred") with an aggregate value of $13.2 million, or $3.30 per share (the
"Series C Issue Price"). Air Wisconsin had leased each of these
CRJ-200
regional jets and GE engines from Southshore. In January 2020, Harbor filed a
Certificate of Designations, Preferences, and Rights of Series C Convertible
Redeemable Preferred Stock ("Certificate of Designations") with the Secretary of
State of the State of Delaware, which establishes the rights, preferences,
privileges, qualifications, restrictions and limitations relating to the
Series C Preferred.

Each share of Series C Preferred was initially convertible, at any time after
issuance, into that number of shares of common stock determined by dividing the
then applicable Series C Liquidation Amount (defined below) by $0.80, subject to
certain adjustments set forth in the Certificate of Designations (the
"Conversion Price"). The adjusted Conversion Price as of the date of this filing
is $0.15091.

The conversion of Series C Preferred is subject to a limitation on the number of
shares of the common stock that may be issued upon conversion of Series C
Preferred equal to the sum of (a) 16,500,000, plus (b) the quotient of (i) the
aggregate amount of all accrued and unpaid Preferential Dividends divided by
(ii) $0.80, (the "Conversion Cap") plus (c) the quotient of (i) the number of
shares of Series C Preferred issued as PIK Dividends multiplied by the Series C
Issue Price, divided by (ii) $0.80. Any outstanding shares of Series C Preferred
that may not be converted pursuant to the limitation described herein (the
"Conversion Cap Excess Shares"), from and after December 31, 2022, in addition
to the Preferential Dividends, shall accrue cumulative quarterly dividends equal
to an amount per share equal to 0.5% of the Series C Liquidation Amount (as
defined below) of each outstanding Conversion Cap Excess Share in the first
quarter after December 31, 2022, and increasing an additional 0.5% of the Series
C Liquidation Amount in each subsequent quarter (the "Conversion Cap Excess
Dividends"). As of March 18, 2022, 754,550 shares of the Series C Preferred are
immediately convertible into 16,500,000 shares of common stock (representing
25.9% of the fully diluted shares of capital stock of Harbor), and the remaining
3,245,450 shares of the Series C Preferred would be deemed Conversion Cap Excess
Shares. For additional information related to the Series C Preferred, refer to
the Annual Report on Form
10-K
of the Company for the year ended December 31, 2020.

On March 30, 2021, June 30, 2021, September 28, 2021, and December 31, 2021, the
board of directors declared a dividend of $198 on the Series C Preferred, which
was paid on March 31, 2021, June 30, 2021, September 30, 2021 and December 30,
2021, respectively.

                                       45

Based on the applicable accounting guidance, Harbor is required to apply
the "if-converted" method
to the Series C Preferred to determine the weighted average number of shares
outstanding for purposes of calculating the net income (loss) per share of
common stock. However, conversion is not assumed for purposes of computing
diluted earnings per share if the effect would be anti-dilutive.

Harbor accounts for its Series C Preferred in accordance with the guidance in ASC Topic 480,


 Distinguishing Liabilities from Equity
. Based on the applicable accounting guidance, preferred stock that is
conditionally redeemable is classified as temporary or "mezzanine" equity.
Accordingly, the Series C Preferred, which is subject to conditional redemption,
is presented at redemption value as mezzanine equity outside of the
stockholders' equity section of the consolidated balance sheets.

Aircraft Operating Leases

As of December 31, 2021 and December 31, 2020, Air Wisconsin had no operating aircraft remaining on lease.



Debt and Credit Facilities

Aircraft Credit Agreements

In seven separate transactions occurring in 2003 and 2004, Air Wisconsin
financed the acquisition of 35
CRJ-200
regional jets through the issuance of senior aircraft notes to a loan trustee on
behalf of a senior lender (the "Lender") and subordinated aircraft notes to the
loan trustee on behalf of a subordinated lender. The senior aircraft notes and
the subordinated aircraft notes were governed by seven credit agreements. Prior
to December 2018, the Lender acquired all of the subordinated aircraft notes
from the subordinated lender.

In December 2018, Air Wisconsin entered into a debt restructuring arrangement
with the Lender, as holder of all of the senior aircraft notes and subordinated
aircraft notes, and a loan trustee for the Lender (the "Loan Trustee"). The
seven original credit agreements were amended and restated as part of that
restructuring, and those seven amended and restated credit agreements (the
"Aircraft Credit Agreements") remain in effect. Prior to the restructuring, the
aggregate outstanding principal amount of the senior aircraft notes and the
subordinated aircraft notes was approximately $246.8 million. Pursuant to the
restructuring, the outstanding principal and accrued interest on the
subordinated aircraft notes were forgiven and deemed paid in full, and the
senior aircraft notes outstanding under the original credit agreements were
cancelled and exchanged for notes in an outstanding principal amount of
$70.0 million. All principal on the senior aircraft notes in excess of
$70.0 million and all interest accrued on the senior aircraft notes prior to
December 24, 2018 were forgiven and deemed paid in full. The notes issued under
the Aircraft Credit Agreements (the "Aircraft Notes") bear interest at the rate
of 4% per annum and mature on December 31, 2025. Interest on the Aircraft Notes
is paid quarterly. The principal amount of the Aircraft Notes is payable in
semi-annual installments of $3.5 million with certain additional amounts payable
based on excess cash flow. Each Aircraft Note issued pursuant to an Aircraft
Credit Agreement is secured by each aircraft acquired with the proceeds of any
of the original seven credit agreements and by certain spare aircraft, spare
engines and spare parts.

The Aircraft Credit Agreements contain covenants that, subject to exceptions
described in the Aircraft Credit Agreements, (i) require Air Wisconsin to
provide certain financial and other information, (ii) provide certain inspection
rights to the Loan Trustee, (iii) restrict Air Wisconsin's ability to
consolidate with or merge into any other person or sell, convey, lease or
otherwise transfer all or substantially all of its assets to any other person,
(iv) restrict Air Wisconsin's ability to make payments to its affiliates, and
(v) grant to the Loan Trustee security interests in certain after-acquired
aircraft, spare engines and spare parts. The Aircraft Credit Agreements also
contain customary events of default, including, without limitation: (a) payment
defaults, (b) breach of covenants, (c) breach of representations and warranties,
(d) cross-defaults, (e) certain bankruptcy-related defaults, (f) the occurrence
of certain judgments, and (g) loss of first priority security interest in
certain collateral. As of December 31, 2021, Air Wisconsin was in compliance
with the covenants under the Aircraft Credit Agreements, and no event of default
existed under the Aircraft Credit Agreements. Neither Harbor nor any of its
other subsidiaries has guaranteed or provided any other credit support with
respect to the Aircraft Notes or other obligations of Air Wisconsin under the
Aircraft Credit Agreements.

Other Credit Agreements

Air Wisconsin entered into a credit agreement with the Lender in June 2017 in
the amount of approximately $14.4 million. This loan bore interest at a rate of
5% per annum, was secured by certain aircraft, spare engines and spare parts and
was paid in full in December 2020.

In January 2018, Air Wisconsin entered into a second credit agreement with the
Lender to borrow approximately $15.2 million in the year ended December 31,
2018. That agreement was amended several times to increase the amount of the
loans outstanding to $27.0 million and to extend the maturity date. The loans
under the 2018 credit agreement bore interest at a rate of 5% per annum, were
secured by certain aircraft, spare engines and spare parts and was paid in full
in the third quarter of 2021.

Paycheck Protection Program

In April 2020, Air Wisconsin received the $10.0 million SBA Loan under the PPP
established under the CARES Act and administered by the SBA. The loan was
forgivable subject to certain limitations, including that the loan proceeds be
used to retain workers and for payroll, mortgage payments, lease payments, and
utility payments. The entire principal amount and accrued interest were forgiven
in August 2021, in the amount of $10.1 million, which was recorded as gain on
extinguishment of debt in the consolidated statements of operations included
within this Annual Report.

Payroll Support Program

In April 2020, Air Wisconsin entered into the
PSP-1
Agreement with the Treasury for payroll support under the CARES Act and received
approximately $42.2 million, all of which was received in the year ended
December 31, 2020. In March 2021, Air Wisconsin entered into the
PSP-2
Agreement with the Treasury for payroll support under the PSP Extension Law and
received approximately $33.0 million, all of which was received in the six
months ended June 30, 2021. In June 2021 the Treasury entered into the
PSP-3
Agreement with Air Wisconsin for payroll support under the American Rescue Plan,
and Air Wisconsin received approximately $33.3 million, all of which was
received in the year ended December 31, 2021.

The PSP Agreements contain various covenants, including that (i) the payroll
support proceeds must be used exclusively for the payment of wages, salaries and
benefits, (ii) Air Wisconsin cannot involuntarily terminate or furlough any
employee or reduce any employee's pay rates or benefits without that employee's
consent, in any case prior to certain dates, (iii) Air Wisconsin cannot pay
total compensation to certain employees in excess of certain total compensation
caps, (iv) Air Wisconsin cannot pay dividends or make other capital
distributions prior to certain dates, and (v) neither Air Wisconsin nor any of
its affiliates can purchase an equity security of Air Wisconsin or any direct or
indirect parent company of Air Wisconsin that is listed on a national securities
exchange prior to certain dates. If Air Wisconsin fails to comply with its
obligations under the PSP Agreements, it may be required to repay some or all of
the funds provided to it under those agreements. Any such default, acceleration,
insolvency or failure to comply would likely have a material adverse effect on
our business. For additional information, refer to Note 8,
Commitments and Contingencies
, in our consolidated financial statements included in this Annual Report.

Maintenance Commitments

Air Wisconsin has entered into two
non-exclusive
heavy maintenance services agreements for certain maintenance, repair and
modification services with respect to airframes owned or operated by Air
Wisconsin, and one exclusive engine maintenance agreement to perform certain
maintenance, repair, restoration, overhaul, modification and other services on
aircraft engines owned or operated by Air Wisconsin. Two of the
non-exclusive
heavy maintenance services agreements are subject to certain escalation of labor
rates and have an initial term through September 2022 and May 2024,
respectively, but Air Wisconsin has the right to extend the term for up to two
renewal terms of one year each, on the same terms and conditions as during the
initial terms. The exclusive engine maintenance agreement is subject to an
annual escalation and had an initial term through May 2021. Air Wisconsin
exercised its right to extend the term through May 2023. No additional renewal
options are available under the current agreement.

Off-Balance
Sheet Arrangements

An
off-balance
sheet arrangement is any transaction, agreement or other contractual arrangement
involving an unconsolidated entity under which a company has (i) made
guarantees, (ii) a retained or a contingent interest in transferred assets,
(iii) an obligation under derivative instruments classified as equity or
(iv) any obligation arising out of a material variable interest in an
unconsolidated entity that provides financing, liquidity, market risk or credit
risk support to us, or that engages in leasing, hedging or research and
development arrangements with us.

We have no
off-balance
sheet arrangements that would have a material current or future effect on the
Company's financial condition, results of operations or liquidity.

Critical Accounting Policies
and Estimates

We prepare our consolidated financial statements in accordance with generally
accepted accounting principles. Critical accounting policies are those policies
that are most important to the preparation of our consolidated financial
statements and require management's subjective and complex judgments due to the
need to make estimates about the effect of matters that are inherently
uncertain. In doing so, we must make estimates and assumptions that affect our
reported amounts of assets, liabilities, revenue and expenses, as well as
related disclosure of contingent assets and liabilities. To the extent that
there are material differences between these estimates and actual results, our
financial condition or results of operations would be affected. We base our
estimates on past experience and other assumptions that we believe are
reasonable under the circumstances, and we evaluate these estimates on an
ongoing basis. We refer to accounting estimates of this type as critical
accounting policies, which we discuss below.

We have identified the accounting policies discussed below as critical to us.
The discussion below is not intended to be a comprehensive list of our
accounting policies. Our significant accounting policies are more fully
described in Note 1,
Summary of Significant Accounting Policies
, in our audited consolidated financial statements included in this Annual
Report.

Revenue Recognition



Because our flights are distinct services that have the same pattern of transfer
to the customer, satisfied over time with the measure of progress for each
flight deemed to be substantially the same, the flight services promised in the
United capacity purchase agreement represent a series of services that are
accounted for as a single performance obligation. Therefore, our contract
revenues are recognized when service is provided and our performance obligation
is determined on a per completed flight basis. The performance obligation of
each completed flight is measured using departures. In addition, as a result of
an amendment to the United capacity purchase agreement in October 2020 (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.

As discussed above, 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 first six months of 2021, Air Wisconsin deferred $15.4 million of fixed
revenues, and in the last six months of 2021 Air Wisconsin recognized
$13.4 million of fixed revenues that were previously deferred, compared to a
deferral of $43.2 million of fixed revenues in the year ended December 31, 2020.
In addition, Air Wisconsin's fixed revenue rate was adjusted in the fourth
quarter of 2021 to account for the opening of a crew base. This resulted in Air
Wisconsin recognizing $0.5 million as a cumulative catchup adjustment based on
prior and future expected departures and total revenues of $0.5 million, with a
net adjustment to deferred revenues of ($0.4) million for the year ended
December 31, 2021. 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. With respect to the stand ready performance
obligation, for the years ended December 31, 2021 and December 31, 2020, Air
Wisconsin recorded $15.1 million and $21.4 million in revenue, respectively.


                                       48

Our revenues could be impacted by a number of factors, such as our flight
schedules, terminations, labor shortages, weather, our estimates used to
determine the amount of revenue we defer under the United capacity purchase
agreement, and any incentive payments or performance penalties under the United
capacity purchase agreement. Under that agreement, Air Wisconsin is eligible to
receive incentive compensation or pay performance penalties upon the achievement
of, or failure to achieve, certain performance criteria. The incentives and
penalties are defined in the agreement and are measured and determined on a
monthly basis. At the end of each month, Air Wisconsin calculates the incentives
achieved, net of any penalties, during that period and recognizes revenue
attributable to the agreement accordingly, subject to the variable constraint
guidance under Topic 606.

The United capacity purchase agreement includes weekly provisional cash payments
based on a projected level of flying each month. Air Wisconsin and United
subsequently reconcile these payments to the actual completed flight activity on
a monthly basis.

Other revenue is immaterial and primarily consist of the sales of parts to other airlines. The transaction price for the sale of these parts occurs at fair market value.

Long-Lived Assets



As of December 31, 2021, we had approximately $124.7 million of property and
equipment and related assets net of accumulated depreciation. In accounting for
these long-lived assets, we make estimates about the expected useful lives of
the assets, the expected residual values of certain of these assets, and the
potential for impairment based on the fair value of the assets and the cash
flows they generate. Factors indicating potential impairment include, but are
not limited to, significant decreases in the market value of the long-lived
assets, a significant change in the condition of the long-lived assets and
operating cash flow losses associated with the use of the long-lived assets.
When considering whether or not impairment of long-lived assets exists, we group
similar assets together at the lowest level for which identifiable cash flows
are largely independent of the cash flows of other assets and liabilities and
compare the undiscounted cash flows for each asset group to the net carrying
amount of the assets supporting the asset group. Factors that may impact our
estimates used for depreciation include anticipated useful lives and estimated
residual values. Estimates may be impacted by future economic uncertainties. At
December 31, 2021, we had 64 aircraft in service under the United capacity
purchase agreement.

Income Taxes



The Company utilizes the asset and liability method for accounting for income
taxes. Under the asset and liability 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.

                                       49
