DEAR SHAREHOLDERS:

Thank you for participating in the  
ongoing success of Willis Lease 
Finance Corporation. Approaching 
our 35th year, we are celebrating 
our market position as the premier 
engine lessor in the world with over 
700 assets owned and managed. We 
have delivered on our promise to 
provide the most comprehensive, 
reliable, and innovative fleet solutions, 
to include aircraft and engine leasing, 
materials, asset management and 
technical services, as well as tailored 
combinations to meet our customers’ 
unique needs.  

We have grown far beyond our 
origins as a lessor. We have become 
a power plant-focused aftermarket 
solutions provider.  

FINANCIAL RESULTS  
2018 was the most productive year to 
date for our shareholders, measured 
both by our pre-tax earnings as well 
as our share price. Compared to our 
publicly traded peer group, Willis 
Lease has provided superior total 
returns to its shareholders over the 
preceding 1-, 3- and 5-year periods 
(see chart on facing page). As a 
history enthusiast, I can only hope 
that the past is prologue.

Your Company is being both  
disruptive and transformative at the 
same time. Disruptive in that Willis 
Lease is changing the paradigm of 
airlines relying upon dedicated  
spares through ownership and  
long-term lease, to a more efficient 
“just in time” approach, leveraging 
Willis’ extensive portfolio of engines 
and its ability to accurately forecast 
maintenance events. 

And transformative in the way that 
customers have embraced the full 
spectrum of products and services  
being offered by Willis Lease. No 
longer is Willis simply offering lease 
engines; rather, the Company is 
working in close coordination with 
airline engineering departments to 
find tangible ways to create efficiency 
and save airlines money. We believe 
the future will be driven by 
availability and outsourcing, and  
we will be there to lead the charge.

Our three business units – Leasing, 
Asset Management and Materials 
Support – together comprise the 
Willis PlatformTM.

“

We selected Willis  

Lease because of their 

unique ability to create and 

deliver a comprehensive 

solution that will  

significantly lower the 

risk and cost of  

transitioning to our  

fleet of new technology 

A320NEO aircraft.  

We are looking forward 

to building a relationship 

with Willis Lease over  

the coming years to  

ensure our single aisle 

fleet transition remains 

seamless.

”

LEASING  
Willis Lease Finance Corporation
Willis Lease, the foundation of  
our Company, continues to grow. 
Our portfolio of engines is the  
largest and most technologically 
advanced in our history. We made a 
critical investment in new technology 
and are introducing approximately  
$435 million of new LEAP and 
GEnx engines, as well as the latest  
technology v2500s into our  
portfolio. Overall, we acquired  
nearly half a billion dollars of assets 
in 2018, increasing the book value  
of our portfolio by roughly 25%.  

These acquisitions represent a giant 
step forward, cementing Willis Lease’s 
reputation as a pioneering lessor in 
the aviation sector.

ASSET MANAGEMENT  
Willis Asset Management Limited
Willis Asset Management, which  
became part of the Company in 
2016, is a thriving asset management 
business serving our customers in  
the critical areas of delivering data 
analytics, fleet planning and general 
power plant consulting. Customers 
are also exploiting the benefits of 
access to cost-effective materials and  
availability of lease engines.

MATERIALS SUPPORT  
Willis Aeronautical Services, Inc.
As a leading supplier of surplus  
engine material to the global  
aviation industry, Willis Aero  
is fully integrated with our  
overall enterprise. 

As a profitable and essential part  
of Willis Lease, we see Willis Aero  
continuing to grow and provide 
key support services to our airline 
and maintenance repair and  
overhaul (MRO) customers.

CEO CUSTOMER OUTREACH TOURS: 2018 DESTINATIONS

11-28 February 2018 (12 destinations)

14 October – 29 November 2018 (28 destinations)

The integration of our three  
business units has proven beneficial 
not only for our shareholders,  
but for our customers as well.  
We have created efficiency gains 
for customers who embrace our 
strategy of combining data-driven 
fleet planning capabilities and  
engine portfolio utilization,  
minimizing maintenance spend 
and the carrying costs associated 
with underutilized assets. 

By engaging with our customers  
from different angles, we have 
strengthened relationships with 
our airline customers around  
the world. The past year has seen 
further growth in our relationships 
with MROs, our joint venture 
partners, and our capital providers, 
as evidenced by our fourth  
successful securitization,  
completed in August. 

EXPANDING OUR GLOBAL REACH  
We participated in two major  
regional tours last year using our  
corporate aircraft. These tours were 
carefully planned to introduce  
customers to representatives from 

4

each business unit with a focus 
on the customer’s specific region. 
During these tours, both I and our 
six-person regional team visited 
customers in 30 countries – covering 
four continents over the course of 60 
days, and calling on over 75 airlines 
and MROs. I am delighted to report 
that our customers are extremely 
pleased with both the service and  
the solutions we provide.

Thank you everyone, 

about 18hrs 30min from 

first request to engine 

released. Great work! 

                              23 May 2018

Again, thank you for 

your excellent support. 

Willis has gone from an 

unfamiliar contact to a 

very important provider 

in really no time. 

”

               13 June 2018

   Thomas Krook     

Director, Technical Operations 
   Novair

The market has changed and so have 
we. When I began the Company 
the first engine we purchased cost 
$350,000. Recently, we purchased 
an engine for $27 million. We are 
proud to be an aviation pioneer 
and continue to build our legacy 
through innovation, close customer 
relationships and the hard work of 
our dedicated employees – some of 
whom have been with us for more 
than 20 years!

In an industry that has historically 
been dominated by men, we are also 
proud that we continue to value 
women in key leadership roles. 

Again, many thanks for being  
long-term shareholders. We could 
not have achieved this level of  
success without your ongoing trust 
and loyalty. 

Sincerely,

Charles F.  Willis, IV 
Chairman and Chief Executive Officer

March 29, 2019

Through my travels, I have  
concluded that Willis Lease presents 
a more formidable alternative to  
original equipment manufacturers  
(OEMs) than we have in the past.  
OEMs are industrially focused, and 
their goal is to sell the maximum 
number of engines and engine parts 
possible. On the other hand, our 
Company provides not only assets, 
but financial solutions as well, with 
the goal of creating maximum  
efficiency for airlines. 

ConstantThrustTM is an example  
of one such service in which we 
provide ongoing assistance to  
companies undergoing fleet  
transitions. Our ConstantThrustTM 
program eliminates the need to  
perform engine overhauls by using 
our serviceable engines to replace 
their unserviceable ones. 

In addition to ConstantThrustTM,  
we are in the nascent stages of  
developing another ground-breaking  
service for our customers:  
ConstantAccessTM.  This product  
will allow us to provide guaranteed 
availability of engines worldwide, 
again allowing airlines to invest 
their resources in operations or new 
aircraft, rather than in underutilized 
standby engines. You will be hearing 
more about both ConstantThrustTM 
and ConstantAccessTM going forward.

INTRODUCTION 

PART I

Willis  Lease  Finance  Corporation  with  its  subsidiaries  (“WLFC”)  is  a  leading  lessor  and  servicer  of  commercial 
aircraft and aircraft engines. Our principal business objective is to build value for our shareholders by acquiring commercial 
aircraft and engines and managing those assets in order to provide a return on investment, primarily through lease rent and 
maintenance reserve revenues, as well as through management fees earned for managing assets owned by other parties. As 
of December 31, 2018, we had a total lease portfolio consisting of 244 engines and related equipment, 17 aircraft and 10 
other leased parts and equipment with 81 lessees in 47 countries with an aggregate net book value of $1,673.1 million. In 
addition to our owned portfolio, as of December 31, 2018, we managed a total lease portfolio of 440 engines, aircraft and 
related equipment for other parties.  

In 2013, we launched Willis Aeronautical Services, Inc. (“Willis Aero”), a wholly-owned subsidiary, whose primary 
focus is the sale of aircraft engine parts and materials through the acquisition or consignment from third parties of aircraft 
and engines.   

In  2016,  we  purchased,  through  our  wholly  owned  subsidiary  Willis  Asset  Management  Limited  (“Willis  Asset 
Management”), the business and assets of Total Engine Support Limited (“TES”).  TES was the engine management and 
consulting business of the TES Aviation Group. Willis Asset Management had 404 engines, excluding WLFC engines, 
under management as of December 31, 2018. 

We are a Delaware corporation, incorporated in 1996. Our executive offices are located at 4700 Lyons Technology 
Parkway,  Coconut  Creek,  Florida  33073.  We  transact  business  directly  and  through  our  subsidiaries  unless  otherwise 
indicated.

We  maintain  a  website  at  www.willislease.com  where  our  Annual  Reports  on  Form 10-K,  Quarterly  Reports  on 
Form 10-Q, Current Reports on Form 8-K and all amendments to those reports are available without charge, as soon as 
reasonably practicable following the time they are filed with or furnished to the SEC. You may read and copy any materials 
we file with the SEC at the SEC’s public reference room at 100 F Street, NE, Washington, DC 20549. You may obtain 
information  on  the  operation  of  the  Public  Reference  Room by  calling  the  SEC  at  1-800-SEC-0300.  The  SEC  also 
maintains an electronic Internet site that contains our reports, proxies and information statements, and other information 
at http://www.sec.gov. 

We separate our business into two reportable segments, Leasing and Related Operations and Spare Parts Sales. Our 

business activities by reportable segment are described below. 

Leasing and Related Operations 

Our strategy is to lease aircraft and aircraft engines and provide related services to a diversified group of commercial 
aircraft operators and maintenance, repair and overhaul organizations (“MROs”) worldwide. Commercial aircraft operators 
need engines in addition to those installed on the aircraft that they operate. These spare engines are required for various 
reasons including requirements that engines be inspected and repaired at regular intervals based on equipment utilization. 
Furthermore,  unscheduled  events  such  as  mechanical  failure,  Federal  Aviation  Administration  (“FAA”)  airworthiness 
directives or manufacturer-recommended actions for maintenance, repair and overhaul of engines result in the need for 
spare engines. Commercial aircraft operators and others in the industry generally estimate that the total number of spare 
engines needed is between 10% and 14% of the total number of installed engines. Industry research suggests that there are 
nearly 45,000 engines installed on commercial aircraft. Accordingly, it is estimated that there are 4,500 spare engines in 
the market, including both owned and leased spare engines. 

Our engine portfolio consists of noise-compliant Stage IV commercial jet engines manufactured by CFMI, General 
Electric, Pratt & Whitney, Rolls Royce and International Aero Engines. These engines generally may be used on one or 

3

more aircraft types and are the most widely used engines in the world, powering Airbus, Boeing, Bombardier and Embraer 
aircraft. 

The  Company  acquires  engines  for  its  leasing  portfolio  in  a  number  of  ways.  It  enters  into  sale  and  lease  back 
transactions with operators of aircraft and providers of engine maintenance cost per hour services. We also purchase both 
new and used engines that are subject to a lease when purchased and on a speculative basis (i.e. without a lease attached 
from manufacturers or other parties which own such engines). 

Total revenues from our Leasing and Related Operations reportable segment was 88.2%, 89.1% and 92.8% of the 

respective total consolidated revenue for the years ended December 31, 2018, 2017 and 2016, respectively. 

Spare Parts Sales

Our wholly owned subsidiary Willis Aero primarily engages in the sale of aircraft engine parts and materials through 
the acquisition or consignment of engines from third parties or from the leasing portfolio. The launch of this business 
segment in 2013 positioned our Company to provide end-of-life solutions for the growing supply of surplus aircraft and 
engines. With the establishment of Willis Aero, we are able to manage the full lifecycle of our lease assets, enhance the 
returns on our engine portfolio and create incremental value for our shareholders. 

INDUSTRY BACKGROUND - THE DEMAND FOR LEASED AIRCRAFT ENGINES 

Historically, commercial aircraft operators owned rather than leased their spare engines. As engines become more 
powerful and technically sophisticated, they also become more expensive to acquire and maintain. In part due to cash 
constraints on commercial aircraft operators and the costs associated with engine ownership, commercial aircraft operators 
have become more cost-conscious and now utilize operating leases for a portion of their spare engines and are therefore 
better able to manage their finances in this capital-intensive business. Engine leasing is a specialized business that has 
evolved into a discrete sector of the commercial aviation market. Participants in this sector need access to capital, as well 
as specialized technical knowledge, in order to compete successfully. 

Growth in the spare engine leasing industry is dependent on two fundamental drivers: 

(cid:120)

(cid:120)

the number of commercial aircraft, and therefore engines, in the market; and 

the proportion of engines that are leased, rather than owned, by commercial aircraft operators. 

We believe both drivers will increase over time. 

Increased number of aircraft, and therefore engines, in the market

We believe that the number of commercial and cargo aircraft, and hence spare engines, will increase. Boeing projects 
4.7% annual growth in the global commercial jet fleet, doubling the current fleet to over 42,000 aircraft by 2037. Aircraft 
equipment manufacturers have predicted such an increase in aircraft to address the rapid growth of both passenger and 
cargo traffic in the Asian markets, as well as demand for new aircraft in more mature markets. 

Increased lease penetration rate

Spare engines provide support for installed engines in the event of routine or other engine maintenance or unscheduled 

removal. The number of spare engines needed to service any fleet is determined by many factors. These factors include: 

(cid:120)

(cid:120)

(cid:120)

the number and type of aircraft in an aircraft operator’s fleet; 

the geographic scope of such aircraft operator’s destinations; 

the time an engine is on-wing between removals; 

4

(cid:120)

(cid:120)

average shop visit time; and 

the  number  of  spare  engines  an  aircraft  operator  requires  in  order  to  ensure  coverage  for  predicted  and 
unscheduled removals. 

We believe that commercial aircraft operators are increasingly considering their spare engines as significant capital 
assets, where operating leases may be more attractive than finance leases or ownership of spare engines. We believe that 
currently as many as 35% to 40% of the spare engine market falls under the category of leased engines. Industry analysts 
have forecast that the percentage of leased engines is likely to increase over the next 15 years as engine leasing follows 
the growth of aircraft leasing. We believe this is due to the increasing cost of newer engines, the anticipated modernization 
of  the  worldwide  aircraft  fleet  and  the  significant  cost  associated  therewith,  and  the  emergence  of  new  niche-focused 
airlines which generally use leasing in order to obtain their capital assets. 

ENGINE LEASING 

As of December 31, 2018, all of our leases to air carriers, manufacturers and MROs are operating leases as opposed 
to finance leases. Under operating leases, we retain the potential benefit and assume the risk of the residual value of the 
equipment,  in  contrast  to  finance  leases  where  the  lessee  has  more  of  the  potential  benefits  and  risks  of  ownership. 
Operating leases allow commercial aircraft operators greater fleet and financial flexibility due to the relatively small initial
capital outlay necessary to obtain use of the aircraft equipment, and the availability of short and long term leases to better 
meet their needs. Operating lease rates are generally higher than finance lease rates, in part because of the lessor retained 
residual value risk. 

We describe all of our current leases as “triple-net” operating leases. A triple-net operating lease requires the lessee 
to make the full lease payment and pay any other expenses associated with the use of the engines, such as maintenance, 
casualty  and  liability  insurance,  sales  or  use  taxes  and  personal  property  taxes.  The  leases  contain  detailed  provisions 
specifying the lessees’ responsibility for engine damage, maintenance standards and the required condition of the engine 
upon return at the end of the lease. During the term of the lease, we require the lessee to maintain the engine in accordance 
with an approved maintenance program designed to meet applicable regulatory requirements in the jurisdictions in which 
the lessee operates. 

We try to mitigate risk where possible. For example, we make an analysis of the credit risk associated with the lessee 
before entering into any significant lease transaction. Our credit analysis generally consists of evaluating the prospective 
lessee’s financial standing by utilizing financial statements and trade and/or banking references. In certain circumstances, 
we may require our lessees to provide additional credit support such as a letter of credit or a guaranty from a bank or a 
third party or a security deposit. We also evaluate insurance and expropriation risk and evaluate and monitor the political 
and legal climate of the country in which a particular lessee is located in order to determine our ability to repossess our 
engines should the need arise. Despite these guidelines, we cannot give assurance that we will not experience collection 
problems or significant losses in the future. See “Risk Factors” below. 

At the commencement of a lease, we may collect, in advance, a security deposit normally equal to at least one month’s 
lease payment. The security deposit is returned to the lessee after all lease return conditions have been met. Under the 
terms of some of our leases, during the term of the lease, the lessee pays amounts to us based on usage of the engine, which 
is referred to as maintenance reserves or use fees, which are designed to cover the expected future maintenance costs. For 
those leases in which the maintenance reserves are reimbursable to the lessee, maintenance reserves are collected and are 
reimbursed to the lessee when qualifying maintenance is performed. Under longer-term leases, to the extent that cumulative 
use fee billings are inadequate to fund expenditures required prior to return of the engine to us, the lessee is obligated to 
cover the shortfall.  

During the lease period, our leases require that maintenance and inspection of the leased engines be performed at 
qualified maintenance facilities certified by the FAA or its foreign equivalent. In addition, when an engine becomes off-
lease,  it  undergoes  inspection  to  verify  compliance  with  lease  return  conditions.  Our  management  believes  that  our 

5

attention to our lessees and our emphasis on maintenance and inspection helps preserve residual values and generally helps 
us to recover our investment in our leased engines. 

Upon termination of a lease, we will either enter into a new lease, sell or part out the related engines or airframe. The 

demand for aftermarket engines for either sale or lease may be affected by a number of variables, including: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

general market conditions; 

regulatory  changes  (particularly  those  imposing  environmental,  maintenance  and  other  requirements  on  the 
operation of engines); 

changes in demand for air travel; 

fuel costs; 

changes in the supply and cost of aircraft equipment; and 

technological developments. 

The value of a particular used engine or airframe varies greatly depending upon its condition, the maintenance services 
performed  during  the  lease  term  and,  as  applicable,  the  number  of  hours  or  cycles  remaining  until  the  next  major 
maintenance is required. If we are unable to lease or sell engines on favorable terms, our financial results and our ability 
to service debt may be adversely affected. See “Risk Factors” below. 

The value of a particular model of engine is heavily dependent on the status of the types of aircraft on which it is 
installed. We believe values of engines tend to be stable so long as the host aircraft for the engines as well as the engines 
themselves are still being manufactured. Prices will also tend to remain stable and even rise after a host aircraft is no longer
manufactured so long as there is sufficient demand for the host aircraft. However, the value of an engine begins to decline 
rapidly once the host aircraft begins to be retired from service and/or parted out in significant numbers. Values of engines 
also may decline because of manufacturing defects that may surface subsequently. 

As of December 31, 2018, we had a total lease portfolio consisting of 244 engines and related equipment, 17 aircraft 
and 10 other leased parts and equipment with a net book value of $1,673.1 million. As of December 31, 2017, we had a 
total  lease  portfolio  consisting  of  225  aircraft  engines  and  related  equipment,  16  aircraft  and  7  other  leased  parts  and 
equipment, with a net book value of $1,342.6 million. 

As of December 31, 2018 minimum future rentals under non-cancelable operating leases of these engines, related 

equipment and aircraft assets were as follows:

As of December 31, 2018, we had 81 lessees of commercial aircraft engines and related equipment, aircraft, and other 
leased parts and equipment in 47 countries. We believe the loss of any one customer would not have a significant long-
term adverse effect on our business. We operate in a global market in which our engines are easily transferable among 
lessees located in many countries, which stabilizes demand and allows us to recover from the loss of a particular customer. 
As a result, we do not believe we are dependent on a single customer or a few customers, the loss of which would have a 
material adverse effect on our revenues.

In 2011 we entered into an agreement with Mitsui & Co., Ltd. to participate in a joint venture formed as a Dublin-
based Irish limited company — Willis Mitsui & Company Engine Support Limited (“WMES”) for the purpose of acquiring 
and leasing jet engines. Each partner holds a fifty percent interest in the joint venture. WMES owned a lease portfolio of 
32 engines and one aircraft with a net book value of $234.8 million as of December 31, 2018. Our investment in the joint 
venture is $34.2 million as of December 31, 2018. 

In  2014  we  entered  into  an  agreement  with  China  Aviation  Supplies  Import  &  Export  Corporation  (“CASC”)  to 
participate in a joint venture named CASC Willis Engine Lease Company Limited (“CASC Willis”), a new joint venture 
based in Shanghai, China. Each partner holds a fifty percent interest in the joint venture. CASC Willis acquires and leases 
jet engines to Chinese airlines and concentrates on meeting the fast growing demand for leased commercial aircraft engines 
and aviation assets in the People’s Republic of China. During 2016, CASC was reorganized, with portions of its partnership 
interest in CASC Willis being transferred to three Chinese airlines and another government-owned entity. The 2016 CASC 
reorganization resulted in no voting structure change to the joint venture. CASC Willis owned a lease portfolio of four 
engines with a net book value of $51.9 million as of December 31, 2018. Our investment in the joint venture is $13.8 
million as of December 31, 2018.

AIRCRAFT LEASING 

As of December 31, 2018, we owned and leased seven Boeing 737 aircraft, six A319-111 aircraft, and four A319-112 

aircraft with an aggregate net book value of $183.7 million. 

Our aircraft leases are “triple-net” leases and the lessee is responsible for making the full lease payment and paying 
any other expenses associated with the use of the aircraft, such as maintenance, casualty and liability insurance, sales or 
use taxes and personal property taxes. In addition, the lessee is responsible for normal maintenance and repairs, engine and 
airframe overhauls, and compliance with return conditions of flight equipment on lease. Under the provisions of many 
leases,  for  certain  engine  and  airframe  overhauls,  we  reimburse  the  lessee  for  costs  incurred  up  to  but  not  exceeding 
maintenance reserves the lessee has paid to us. Maintenance reserves are designed to cover the expected maintenance costs. 
The  lessee  is  also responsible  for  compliance  with  all  applicable  laws  and regulations with respect  to  the  aircraft. We 
require our lessees to comply with FAA requirements. We periodically inspect our leased aircraft. Generally, we require a 
deposit as security for the lessee’s performance of obligations under the lease and the condition of the aircraft upon return. 
In addition, the leases contain extensive provisions regarding our remedies and rights in the event of a default by the lessee 
and specific provisions regarding the condition of the aircraft upon return. The lessee is required to continue to make lease 
payments under all circumstances, including periods during which the aircraft is not in operation due to maintenance or 
grounding. 

SPARE PARTS SALES 

The sale of spare parts is managed by the Company’s wholly owned subsidiary, Willis Aero. Willis Aero primarily 
engages in the sale of aircraft engine parts and materials through the acquisition or consignment from third parties or from 
the leasing portfolio. The launch of this new business segment in 2013 positioned our Company to provide end-of-life 
solutions for the growing supply of surplus aircraft and engines. With the establishment of Willis Aero, we are able to 
manage the full lifecycle of our lease assets, enhance the returns on our engine portfolio and create incremental value for 
our shareholders.  As of December 31, 2018, spare parts inventory had a carrying value of $48.9 million. 

ASSET MANAGEMENT 

In 2016, Willis Asset Management purchased the business and assets of TES, the engine management and consulting 
business of the TES Aviation Group.  Willis Asset Management is an asset management, technical services and consultancy 
business.  Willis Asset Management had 404 engines, excluding WLFC engines, under management as of December 31, 
2018.

OUR COMPETITIVE ADVANTAGES 

We are uniquely positioned in the market and remain competitive, in part, due to the following advantages: 

(cid:120) We have an entrepreneurial culture and our size and independent ownership structure gives us a unique ability 
to move faster than our competition. We were founded in 1985 as a startup venture by our Chief Executive Officer, 
Charles F. Willis, IV, and we continue to foster an entrepreneurial attitude among our executives and employees. 
Unlike most other aircraft engine leasing companies, we are not tied to a particular manufacturer and are not part 
of  a  larger  corporate  entity.  As  a  result,  we  can  react  more  nimbly  to  customer  demands  and  changes  in  the 
industry. 

(cid:120) Our independent ownership allows us to meet our customer needs without regard to any potentially conflicting 
affiliate demands to use their engines or services. Many of the aircraft engine leasing companies with which we 
compete are owned in whole or part by aircraft engine manufacturers. As a result, these leasing companies are 
inherently motivated to lease to customers the aircraft equipment that is manufactured by their owners, regardless 
of whether that equipment best meets the needs of their customers. As an independent public company we have 
the ability to work with customers to correctly identify their needs and provide them with the engines, equipment 
and services that are best suited to those needs. 

(cid:120) We have significant technical expertise and experience. Our senior management, marketing and sales teams all 
have extensive experience in leasing aircraft engines and equipment. As a result, we possess a deep knowledge 
of the technical details of commercial aircraft engines and maintenance issues associated with these engines that 
enables us to provide our customers with comprehensive and up to date information on the various engine types 
available for lease. 

(cid:120) We have extensive, worldwide industry contacts/relationships. We have developed long-standing relationships 
with aircraft operators, equipment manufacturers and aircraft maintenance organizations around the world. Our 
extensive network of relationships enables us to quickly identify new leasing opportunities, procure engines and 
equipment and facilitate the repair of equipment owned by us and equipment leased by our customers. 

(cid:120) We have a trusted reputation for quality engines and engine records. We have been an independent lessor of 
aircraft engines and engine equipment since 1985. Since that time we have focused on providing customers with 
high quality engines and engine records. As a result of our commitment to these high standards, a significant 
portion of our customer base consists of customers who have leased engines from us previously. 

(cid:120) We have a diverse lease portfolio by customer, geography and asset type. As of December 31, 2018, we had a 
total lease portfolio consisting of 244 engines and related equipment, 17 aircraft and 10 other leased parts and 
equipment with 81 lessees in 47 countries and an aggregate net book value of $1,673.1 million. 

(cid:120) We  have  a  diverse  lease  product  offering  (by  engine  type  and  types  of  leases).  We  lease  a  variety  of  noise-
compliant, Stage IV commercial jet engines manufactured by CFMI, General Electric, Pratt & Whitney, Rolls 
Royce and International Aero Engines. These engines generally may be used on one or more aircraft types and 
are the most widely used engines in the world, powering Airbus, Boeing, Bombardier and Embraer aircraft. We 
offer short and long-term leases, sale/leaseback transactions and engine pooling arrangements where members of 
the  pool  have  quick  access  to  available  spare  engines  from  us  or  other  pool  members,  which  are  typically 
structured as short-term leases. 

COMPETITION 

The markets for our products and services are very competitive, and we face competition from a number of sources. 
These competitors include aircraft engine and aircraft parts manufacturers, aircraft and aircraft engine lessors, airline and 
aircraft service and repair companies and aircraft and aircraft engine spare parts distributors. Many of our competitors have 
substantially  greater  resources  than  us.  Those  resources  may  include  greater  name  recognition,  larger  product  lines, 
complementary  lines  of  business,  greater  financial,  marketing,  information  systems  and  other  resources.  In  addition, 

8

equipment manufacturers, aircraft maintenance providers, FAA certified repair facilities and other aviation aftermarket 
suppliers may vertically integrate into the markets that we serve, thereby significantly increasing industry competition and 
negatively impacting the Company. We can give no assurance that competitive pressures will not materially and adversely 
affect our business, financial condition or results of operations. 

We compete primarily with aircraft engine manufacturers as well as with other aircraft engine lessors. It is common 
for commercial aircraft operators and MROs to utilize several leasing companies to meet their aircraft engine needs and to 
minimize reliance on a single leasing company. 

Our  competitors  compete  with  us  in  many  ways,  including  pricing,  technical  expertise,  lease  flexibility,  engine 
availability, supply reliability, customer service and the quality and condition of engines. Many of our competitors have 
greater financial resources than we do, or are affiliates of larger companies. We emphasize the quality of our portfolio of 
aircraft  engines,  supply  reliability  and  high  level  of  customer  service  to  our  aircraft  equipment  lessees.  We  focus  on 
ensuring  adequate  aircraft  engine  availability  in  high-demand  locations,  dedicate  large  portions  of  our  organization  to 
building relationships with lessees, maintain close day-to-day coordination with lessees and have developed an engine 
pooling arrangement that allows pool members quick access to available spare aircraft engines. 

INSURANCE 

In addition to requiring full indemnification under the terms of our leases, we require our lessees to carry the types of 
insurance customary in the air transportation industry, including comprehensive third party liability insurance and physical 
damage and casualty insurance. We require that we be named as an additional insured on liability insurance with ourselves 
and  our  lenders  normally  identified  as  the  loss  payee  for  damage  to  the  equipment  on  policies  carried  by  lessees.  We 
monitor compliance with the insurance provisions of the leases. We also carry contingent physical damage and third party 
liability insurance as well as product liability insurance. 

GOVERNMENT REGULATION 

Our customers are subject to a high degree of regulation in the jurisdictions in which they operate. For example, the 
FAA regulates the manufacture, repair and operation of all aircraft operated in the United States and equivalent regulatory 
agencies in other countries, such as the European Aviation Safety Agency (“EASA”) in Europe, regulate aircraft operated 
in those countries. Such regulations also indirectly affect our business operations. All aircraft operated in the United States
must be maintained under a continuous condition-monitoring program and must periodically undergo thorough inspection 
and maintenance. The inspection, maintenance and repair procedures for commercial aircraft are prescribed by regulatory 
authorities and can be performed only by certified repair facilities utilizing certified technicians. The FAA can suspend or 
revoke the authority of air carriers or their licensed personnel for failure to comply with regulations and ground aircraft if 
their airworthiness is in question. 

While our leasing and reselling business is not regulated, the aircraft, engines and related parts that we purchase, lease 
and  sell  must  be  accompanied  by  documentation  that  enables  the  customer  to  comply  with  applicable  regulatory 
requirements.  Furthermore,  before  parts  may  be  installed  in  an  aircraft,  they  must  meet  certain  standards  of  condition 
established by the FAA and/or the equivalent regulatory agencies in other countries. Specific regulations vary from country 
to  country,  although  regulatory  requirements  in  other  countries  are  generally  satisfied  by  compliance  with  FAA 
requirements.  With  respect  to  a  particular  engine  or  engine  component,  we  utilize  FAA  and/or  EASA  certified  repair 
stations to repair and certify engines and components to ensure marketability. 

Governmental regulations where the related airframe is registered, and where the aircraft is operated, stipulate noise 
and emissions levels restrictions. For example, jurisdictions throughout the world have adopted noise regulations which 
require  all  aircraft  to  comply  with  Stage  III  noise  requirements.  In  addition  to  the  current  Stage  III  compliance 
requirements,  the  United  States  and  the  International  Civil  Aviation  Organization,  or  “ICAO,”  have  adopted  a  more 
stringent set of “Stage IV” standards for noise levels which apply to engines manufactured or certified from 2006 onward. 
At this time, the United States regulations do not require any phase-out of aircraft that qualify only for Stage III compliance,
but the European Union has established a framework for the imposition of operating limitations on non-Stage IV aircraft.

As of December 31, 2018, most of the engines in our lease portfolio are Stage IV engines and are generally suitable 

for use on one or more commonly used aircraft. 

We believe that the aviation industry will be subject to continued regulatory activity. Additionally, increased oversight 
will continue to originate from the quality assurance departments of airline operators. We have been able to meet all such 
requirements to date, and believe that we will be able to meet any additional requirements that may be imposed. We cannot 
give assurance, however, that new, more stringent government regulations will not be adopted in the future or that any 
such new regulations, if enacted, would not have a material adverse impact on us. 

GEOGRAPHIC AREAS IN WHICH WE OPERATE 

At December 31, 2018, approximately 84% of our on-lease engines, aircraft, and related equipment (all of which we 
sometimes  refer  to  as  “equipment”)  by  net  book  value  are  leased  and  operated  internationally.  Substantially  all  leases 
relating to this equipment are denominated and payable in U.S. dollars, which is customary in the industry. Future leases 
may provide for payments to be made in euros or other foreign currencies. In 2018, we leased our equipment to lessees 
domiciled in eight geographic regions. We are subject to a number of risks related to our foreign operations. See “Risk 
Factors” below. 

The following table displays the regional profile of our lease customer base for the three years ended December 31, 
2018. The United States and Sweden each accounted for more than 10% of our lease rent revenue in 2018. The United 
States was the only country individually that accounted for more than 10% of our lease rent revenue in 2017.  The United 
States and China each accounted for more than 10% of our lease rent revenue in 2016. The tables include geographic 
information about our leased equipment grouped by the lessee’s domicile (which does not necessarily indicate the asset’s 
actual location):

FINANCING/SOURCE OF FUNDS 

We, directly or through our Willis Engine Structured Trust II, III, and IV (“WEST II”, “WEST III”, “WEST IV”) 
asset-backed securitizations (“ABS”) typically acquire engines with a combination of equity capital and funds borrowed 
from financial institutions. In order to facilitate financing and leasing of engines, each engine is generally owned through 
a statutory or common law trust that is wholly-owned by us or our subsidiaries. We usually borrow up to 85% of an engine 
purchase price. Substantially all of our assets secure our related indebtedness. We typically acquire engines from airlines, 
engine manufacturers or from other lessors. From time to time, we selectively acquire engines prior to a firm commitment 
to lease or sell the engine, depending on the price of the engine and market demand with the expectation that we can lease 
or sell such engines in the future. Additionally, for discrete financing purposes, we will enter into bi-lateral and preferred 
financing arrangements from time to time.

EMPLOYEES 

As of December 31, 2018, we had 175 full-time employees (excluding consultants), in sales and marketing, technical 
service and administration. None of our employees are covered by a collective bargaining agreement and we believe our 
employee relations are satisfactory. 

ITEM 1A. RISK FACTORS

The following risk factors and other information included in this Annual Report should be carefully considered. The 
risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently 
known to us or that we currently deem immaterial also may impair our business operations. If any of the following risks 
occur, our business, financial condition, operating results and cash flows could be materially and adversely affected. 

RISKS RELATING TO OUR BUSINESS 

Risks Related to Our Operations 

We are affected by the risks faced by commercial aircraft operators and MROs because they are our customers.

We operate as a supplier of engines, aircraft and related parts (“aviation equipment”) to commercial aircraft operators 
and MROs and are indirectly impacted by all the risks facing commercial aircraft operators and MROs today. The ability 
of  each  lessee  to  perform  its  obligations  under  the  relevant  lease  and  the  demand  of  companies  to  purchase  aviation 
equipment will depend primarily on the lessee’s (or in the case of parts and materials, the purchaser’s) financial condition 
and cash flow. This may be affected by factors beyond our control, including: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

general economic conditions in the countries in which our customers operate, including changes in gross domestic 
product; 

demand for air travel and air cargo shipments; 

increased competition; 

the availability of government support, which may be in the form of subsidies, loans (including export/import 
financing), guarantees, equity investments or otherwise: 

changes  in  interest  rates  and  the  availability  and  terms  of  credit  available  to  commercial  aircraft  operators 
including covenants in financings, terms imposed by credit card issuers, collateral posting requirements contained 
in fuel hedging contracts and the ability of airlines and MROs to make or refinance principal payments as they 
come due; 

geopolitical  and  other  events,  including  concerns  about  security,  terrorism,  war,  public  health  and  political 
instability;

changing political conditions, including risk of rising protectionism and imposition of new trade barriers; 

inclement weather and natural disasters; 

environmental compliance and other regulatory costs, including noise regulations, emissions regulations, climate 
change initiatives, and aircraft age limitations; 

cyber risk, including information hacking, viruses and malware; 

labor contracts, labor costs and strikes or stoppages at commercial aircraft operators; 

11 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

operating costs, including the price and availability of fuel, maintenance costs, and insurance costs and coverages; 

technological developments; 

airport access and air traffic control infrastructure constraints; 

industry capacity, utilization and general market conditions; and 

(cid:120) market prices for aviation equipment. 

To the extent that our customers are negatively affected by these risk factors, we may experience: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

a decrease in demand for some types of aviation equipment in our portfolio; 

greater credit risks from our customers, and a higher incidence of lessee defaults and corresponding repossessions; 

an inability to quickly lease engines and aircraft on commercially acceptable terms when these become available 
through our purchase commitments and regular lease terminations; 

shorter lease terms, which may increase our expenses and reduce our utilization rates; and 

fewer opportunities to manage aviation equipment for other companies, and/or less profitable terms. 

Our operating results vary and comparisons to results for preceding periods may not be meaningful. 

Due to a number of factors, including the risks described in this ITEM 1A, our operating results may fluctuate. These 

fluctuations may also be caused by: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

the timing and number of purchases and sales of engines or aircraft; 

the timing and amount of maintenance reserve revenues recorded resulting from the termination of long term 
leases, for which significant amounts of maintenance reserves may have accumulated; 

the termination or announced termination of production of particular aircraft and engine types; 

the retirement or announced retirement of particular aircraft models by aircraft operators; 

the operating history of any particular engine, aircraft or engine or aircraft model; 

the length of our operating leases; and 

the timing of necessary overhauls of engines and aircraft. 

These risks may reduce our utilization rates, lease margins, maintenance reserve revenues and proceeds from engine 
and aircraft sales, and result in higher legal, technical, maintenance, storage and insurance costs related to repossession 
and the cost of engines being off-lease. As a result of the foregoing and other factors, the availability of engines and aircraft
for lease or sale periodically experiences cycles of oversupply and undersupply of given engine or aircraft models. The 
incidence of an oversupply of engines or aircraft may produce substantial decreases in lease rates and the appraised and 
resale value of aviation equipment and may increase the time and costs incurred to lease or sell engines. 

We  anticipate  that  fluctuations  from  period  to  period  will  continue  in  the  future.  As  a  result,  we  believe  that 
comparisons to results for preceding periods may not be meaningful and that results of prior periods should not be relied 
upon as an indication of our future performance. 

12 

We and our customers operate in a highly regulated industry and changes in laws or regulations may adversely affect 

our ability to lease or sell our engines or aircraft. 

Licenses and consents 

We and our customers operate in a highly regulated industry. A number of our leases require specific governmental 
or regulatory licenses, consents or approvals. These include consents for certain payments under the leases and for the 
export, import or re-export of our engines or aircraft. Consents needed in connection with future leasing or sale of our 
engines or aircraft may not be received timely or have economically feasible terms. Any of these events could adversely 
affect our ability to lease or sell engines or aircraft. 

The  U.S.  Department  of  Commerce,  or  the  “Commerce  Department,”  regulates  exports.  We  are  subject  to  the 
Commerce Department’s and the U.S. Department of State’s regulations with respect to the lease and sale of engines and 
aircraft to foreign entities and the export of related parts. The Commerce Department and the U.S. Department of State 
may, in some cases, require us to obtain export licenses for engines exported to foreign countries. The U.S. Department of 
Homeland Security, through the U.S. Customs and Border Protection, enforces regulations related to the import of engines 
and aircraft into the United States for maintenance or lease and imports of parts for installation on our engines and aircraft.

We are prohibited from doing business with persons designated by the U.S. Department of the Treasury’s Office of 
Foreign Assets Control, or “OFAC,” on its “Specially Designated Nationals List,” and must monitor our operations and 
existing and potential lessees and other counterparties for compliance with OFAC’s rules.  Similarly, sanctions issued by 
the United Nations, the U.S. government, the European Union or other governments could prohibit or restrict us from 
doing business in certain countries, or with certain customers or persons, and we must monitor our operations and existing 
and potential lessees and other counterparties for compliance with such sanctions. 

Anti-corruption Laws 

As a U.S. corporation with significant international operations, we are required to comply with a number of U.S. and 
international laws and regulations, including those combating corruption.  For example, the U.S. Foreign Corrupt Practices 
Act (the “FCPA”) and similar world-wide anti-bribery laws generally prohibit improper payments to foreign officials for 
the purpose of influencing any official act or decision or securing any improper advantage. The scope and enforcement of 
anti-corruption laws and regulations may vary. Although our policies expressly mandate compliance with the FCPA and 
similarly applicable laws, there can be no assurance that none of our employees or agents will take any action in violation 
of our policies. Violations of such laws or regulations could result in substantial civil or criminal fines or penalties. Actual
or alleged violations could also damage our reputation, be expensive to defend, and impair our ability to do business. 

Civil aviation regulation 

Users of engines and aircraft are subject to general civil aviation authorities, including the FAA and the EASA, who 
regulate the maintenance of engines and issue airworthiness directives. Airworthiness directives typically set forth special 
maintenance  actions  or  modifications  to  certain  engine  and  aircraft  types  or  series  of  specific  engines  that  must  be 
implemented for the engine or aircraft to remain in service. Also, airworthiness directives may require the lessee to make 
more frequent inspections of an engine, aircraft or particular engine parts. Each lessee of an engine or aircraft generally is 
responsible for complying with all airworthiness directives. However, if the engine or aircraft is off lease, we may be 
forced to bear the cost of compliance with such airworthiness directives, and if the engine or aircraft is leased, subject to 
the terms of the lease, if any, we may be forced to share the cost of compliance. 

Environmental regulation 

Governmental regulations of noise and emissions levels may be applicable where the related airframe is registered, 
and where the aircraft is operated. For example, jurisdictions throughout the world have adopted noise regulations which 
require  all  aircraft  to  comply  with  Stage  III  noise  requirements.  In  addition  to  the  current  Stage  III  compliance 
requirements, the United States and the ICAO have adopted a more stringent set of “Stage IV” standards for noise levels 

13 

which apply to engines manufactured or certified from 2006 onward. At this time, the United States regulations do not 
require  any  phase-out of  aircraft  that qualify  only  for  Stage III  compliance,  but  the  European  Union  has  established  a 
framework for the imposition of operating limitations on non-Stage IV aircraft. These regulations could limit the economic 
life of our engines and aircraft or reduce their value, could limit our ability to lease or sell the non-compliant engines or 
aircraft or, if modifications are permitted, require us to make significant additional investments in the engines or aircraft 
to make them compliant. 

The United States and other jurisdictions are imposing more stringent limits on the emission of nitrogen oxide, carbon 
monoxide and carbon dioxide emissions from engines, consistent with ICAO standards. These limits generally apply only 
to  engines  manufactured  after  1999.  In  2005,  the  European  Union  launched  an  Emissions  Trading  System  limiting 
greenhouse gas emissions by various industries and persons, including aircraft operators.  Concerns over global warming, 
climate change or other environmental issues could result in more stringent limitations on the operation of older, non-
compliant engines and aircraft. 

Our aircraft, engines or parts could cause bodily injury or property damage, exposing us to liability claims. 

We are exposed to potential liability claims if the use of our aircraft, engines or parts is alleged to have caused bodily 
injury or property  damage.  Our  leases require our  lessees  to  indemnify  us  against  these  claims  and to  carry  insurance 
customary in the air transportation industry, including liability, property damage and hull all risks insurance on our engines 
and on our aircraft at agreed upon levels. We can give no assurance that one or more catastrophic events will not exceed 
insurance coverage limits or that lessees’ insurance will cover all claims that may be asserted against us. Any insurance 
coverage deficiency or default by lessees under their indemnification or insurance obligations may reduce our recovery of 
losses upon an event of loss.

Our financial reporting for lease revenue may be adversely impacted by the new model for lease accounting, as well 

as any future change to current tax laws or accounting principles pertaining to operating or other lease financing.  

Our lessees enjoy favorable accounting and tax treatment generally by using operating leases. Changes in tax laws or 
accounting  principles  that  make  operating  leases  less  attractive  to  our  lessees  could  have  a  material  adverse  effect  on 
demand for our leases and on our business. 

Our  consolidated  financial  statements  are  prepared  in  accordance  with  Generally  Accepted  Accounting  Principles 
(“GAAP”).  If there are future changes in GAAP with regard to how we and our customers must account for leases, it 
could change the way we and our customers conduct our businesses and, therefore, could have the potential to have an 
adverse effect on our business. 

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 
2016-02,  “Leases  (Topic  842)”  (“ASU  2016-02”).  The  FASB  issued  ASU  2016-02  to  increase  transparency  and 
comparability among organizations recognizing lease assets and lease liabilities on the balance sheet and disclosing key 
information about leasing arrangements. Under ASU 2016-02, lessors will account for leases using an approach that is 
substantially equivalent to existing GAAP for sales-type leases, direct financing leases and operating leases. Unlike current 
guidance, however, a lease with collectability uncertainties may be classified as a sales-type lease. If collectability of lease
payments, plus any amount necessary to satisfy a lessee residual value guarantee, is not probable, lease payments received 
will  be  recognized  as  a  deposit  liability  and  the  underlying  assets  will  not  be  derecognized  until  collectability  of  the 
remaining amounts becomes probable. The amendments in this accounting standard update are effective for the Company 
on January 1, 2019, with early adoption permitted. The Company will adopt this accounting standard update effective 
January 1, 2019. The Company plans to adopt the standard using the optional transition method with no restatement of 
comparative periods and a cumulative effect adjustment, if any, recognized as of the date of adoption. 

We may not be adequately covered by insurance. 

By virtue of holding title to engines and aircraft, parties suffering damage as a result of malfunction of an engine or 
aircraft may assert that lessors are strictly liable for losses resulting from the operation of the engines and aircraft. Such 
liability  may  be  asserted  even  under  circumstances  in  which  the  lessor  is  not  directly  controlling  the  operation  of  the 

14 

relevant aircraft.  While we maintain contingent insurance covering losses not covered by our lessees’ insurance, such 
coverage may  not be available in circumstances where the lessees’ insurance coverage is insufficient. In addition, if a 
lessee is not obligated to maintain sufficient insurance, we may incur the costs of additional insurance coverage during the 
related lease. We are required under certain of our debt facilities to obtain political risk insurance for leases to lessees in
specified jurisdictions. We can give no assurance that such insurance will be available at commercially reasonable rates, 
if at all. 

Currently, the U.S. government is still offering war risk insurance to U.S.-certificated airlines; however, most foreign 
governments  have  ceased  this  practice,  forcing  non-U.S.  airlines  back  into  the  commercial  insurance  market  for  this 
coverage.  It  is  unknown  how  long  the  U.S.  government  will  continue  to  offer  war  risk  insurance  and  whether  U.S.-
certificated airlines could obtain war risk insurance in the commercial markets on acceptable terms and conditions. 

We and our lenders generally are named as additional insureds on liability insurance policies carried by our lessees 
and are usually the loss payees for damage to our engines and aircraft. However, an uninsured or partially insured claim, 
or a claim for which third-party indemnification is not available, could have a material adverse effect upon us. A loss of 
an aircraft where we lease the airframe, an engine or other leased equipment could result in significant monetary claims 
for which there may not be sufficient insurance coverage. 

Risks Related to Our Aviation Assets 

The value and lease rates of our engines and aircraft could decline. 

The value of a particular model of engine depends heavily on the types of aircraft on which it may be installed and 
the supply of available engines. We believe values of engines tend to be relatively stable so long as there is sufficient 
demand  for  the  host  aircraft,  and  the demand for  aircraft  depend on numerous  factors,  including  age,  technology,  and 
customer preference. We believe the value of an engine begins to decline rapidly once the host aircraft begins to be retired 
from  service  and/or  used  for  spare  parts  in  significant  numbers.  Certain  types  of  engines  and  aircraft  may  be  used  in 
significant numbers by commercial aircraft operators that are currently experiencing financial difficulties. If such operators 
were to go into liquidation or similar proceedings, the resulting over-supply of engines and aircraft from these operators 
could have  an adverse  effect on  the demand  for  the  affected  engine  and aircraft  types and  the values  of  such  aviation 
equipment. 

Upon termination of a lease, we may be unable to enter into new leases or sell the affected aviation equipment on 

acceptable terms. 

We directly or indirectly own the aviation equipment that we lease to customers and bear the risk of not recovering 
our entire investment through leasing and selling the applicable aircraft and engines. Upon termination of a lease, we seek 
to enter a new lease or to sell or part-out the applicable aviation equipment. We also selectively sell aviation equipment on 
an opportunistic basis. We cannot give assurance that we will be able to find, in a timely manner, a lessee or a buyer for 
aviation  equipment  coming  off-lease  or  for  the  associated  parts.  If  we  do  find  a  lessee,  we  may  not  be  able  to  obtain 
satisfactory lease rates and terms (including maintenance and redelivery conditions) or rates and terms comparable to our 
current leases, and we can give no assurance that the creditworthiness of any future lessee will be equal to or better than 
that  of  the  existing  lessees  of  our  engines.  Because  the  terms  of  engine  leases  may  be  less  than  12  months,  we  may 
frequently need to remarket engines. We face the risk that we may not be able to keep our engines on lease consistently. 

We carry the risk of maintenance and obsolescence for our leased aircraft.  These risks include: 

(cid:120)

(cid:120)

The Company will be subject to the greater maintenance risks and risks of declines in value that apply to aircraft, 
as well as the potentially greater risks of leasing or selling aircraft; 

our aircraft lessees may file for bankruptcy which could result in us incurring greater losses with respect to aircraft 
than with respect to engines; and  

15 

(cid:120)

aircraft technology is constantly improving and, as a result, aircraft of a particular model and type tend to become 
obsolete and less in demand over time, when newer, more advanced and efficient aircraft become available.  

We carry the risk of maintenance for our leased assets. Our maintenance reserves may be inadequate or lessees may 

default on their obligations to perform maintenance, which could increase our expenses.  

Under most of our engine and aircraft leases, the lessee makes monthly maintenance reserve payments to us based on 
the asset’s usage and management’s estimate of maintenance costs. A certain level of maintenance reserve payments on 
the WEST II, WEST III and WEST IV engines are held in related engine reserve restricted cash accounts. Generally, the 
lessee  under  long  term  leases  is  responsible  for  all  scheduled  maintenance  costs,  even  if  they  exceed  the  amounts  of 
maintenance reserves paid. Seventy-one of our leases comprising approximately 27.4% of the net book value of our on-
lease assets at December 31, 2018 do not provide for any monthly maintenance reserve payments to be made by lessees, 
and we can give no assurance that future leases of our engines or aircraft will require maintenance reserves. In some cases, 
including engine and aircraft repossessions, we may decide to pay for refurbishments or repairs if the accumulated use fees 
are inadequate. 

We can give no assurance that our operating cash flows and available liquidity reserves, including the amounts held 
in  the  reserve  restricted  cash  accounts,  will  be  sufficient  to  fund  necessary  engine  and  aircraft  maintenance.  Actual 
maintenance reserve payments by lessees and other cash that we receive may be significantly less than projected as a result 
of numerous factors, including defaults by lessees. Furthermore, we can provide no assurance that lessees will meet their 
obligations  to  make  maintenance  reserve  payments  or  perform  required  scheduled  maintenance  or,  to  the  extent  that 
maintenance reserve payments are insufficient, to cover the cost of refurbishments or repairs. 

Failures by lessees to meet their maintenance and recordkeeping obligations under our leases could adversely affect 
the value of our leased engines and aircraft and our ability to lease the engines and aircraft in a timely manner following 
termination of the leases. 

The  value  and  income  producing  potential  of  an  engine  or  aircraft  depends  heavily  on  it  being  maintained  in 
accordance  with  an  approved  maintenance  system  and  complying  with  all  applicable  governmental  directives  and 
manufacturer requirements. In addition, for an engine or aircraft to be available for service, all records, logs, licenses and 
documentation relating to maintenance and operations of the engine or aircraft must be maintained in accordance with 
governmental and manufacturer specifications. 

Our leases make the lessees primarily responsible for maintaining the engines or aircraft, keeping related records and 
complying with governmental directives and manufacturer requirements. Over time, certain lessees have experienced, and 
may experience in the future, difficulties in meeting their maintenance and recordkeeping obligations as specified by the 
terms of our leases. 

Our ability to determine the condition of the engines or aircraft and whether the lessees are properly maintaining our 
assets  is  generally  limited  to  the  lessees’  reporting  of  monthly  usage  and  any  maintenance  performed,  confirmed  by 
periodic  inspections  performed  by  us  and  third-parties.  A  lessee’s  failure  to  meet  its  maintenance  or  recordkeeping 
obligations under a lease could result in: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

a grounding of the related engine or aircraft; 

a repossession that would likely cause us to incur additional and potentially substantial expenditures in restoring 
the engine or aircraft to an acceptable maintenance condition; 

a need to incur additional costs and devote resources to recreate the records prior to the sale or lease of the engine 
or aircraft; 

loss of lease revenue while we perform refurbishments or repairs and recreate records; and 

16 

(cid:120)

a lower lease rate and/or shorter lease term under a new lease entered into by us following repossession of the 
engine or aircraft. 

Any of these events may adversely affect the value of the engine or aircraft, unless and until remedied, and reduce our 
revenues and increase our expenses. If aviation equipment is damaged during a lease and we are unable to recover from 
the lessee or though insurance, we may incur a loss. 

The advent of superior engine and aircraft technology and higher production levels could cause our existing portfolio 

of aviation equipment to become outdated and therefore less desirable. 

As  manufacturers  introduce  technological  innovations  and  new  types  of  engines  and  aircraft,  certain  engines  and 
aircraft in our existing portfolio of aviation equipment may become less desirable to potential lessees or purchasers. This 
next generation of engines and aircraft is expected to deliver improved fuel consumption and reduced noise and emissions 
with lower operating costs compared to current-technology aircraft. 

The  introduction  of  new  models  of  engines  and  aircraft  and  the  potential  resulting  overcapacity  in  supply,  could 
adversely affect the residual values and the lease rates for our engines and aircraft, our ability to lease or sell our engines
and aircraft on favorable terms, or at all, or result in us recording future impairment charges.

Our customers face intense competition and some carriers are in troubled financial condition. 

As a general matter, commercial aircraft operators with weak capital structures are more likely than well-capitalized 
operators to seek operating leases, and, at any point in time, investors should expect a varying number of lessees and sub-
lessees to experience payment difficulties. As a result of such commercial aircraft operators’ weak financial condition and 
lack of liquidity, a portion of lessees over time may be significantly in arrears in their rental or maintenance payments and 
may default on their lease obligations. Given the size of our portfolio of engines and aircraft, we expect that from time to 
time some lessees will be slow in making, or will fail to make, their payments in full under their leases. As of December 
31,  2018,  we  had  an  aggregate  of  approximately  $4.8  million  in  lease  rent  and  $5.6  million  in  maintenance  reserve 
payments more than 30 days past due. Our inability to collect receivables or to repossess engines, aircraft or other leased 
equipment in the event of a default by a lessee could have a material adverse effect on us. 

We may not correctly assess the credit risk of each lessee or may not be in a position to charge risk-adjusted lease 
rates, and lessees may not be able to continue to perform their financial and other obligations under our leases in the future.
A delayed, reduced or missed rental payment from a lessee decreases our revenues and cash flow and may adversely affect 
our ability to make payments on our indebtedness or to comply with financial covenants in our loan documents (See “Our 
Financing Facilities Impose Restrictions on our Operations”). While we typically experience some level of delinquency 
under our leases, default levels may increase over time, particularly as our portfolio of engines and aircraft ages and if 
economic conditions deteriorate.  

Various  airlines  have  filed  for  bankruptcy  in  the  United  States  and  in  foreign  jurisdictions,  with  some  seeking  to 
restructure their operations and others ceasing operations entirely. In the case of airlines that are restructuring, such airlines 
often reduce their flights or eliminate the use of certain types of aircraft and the related engine types. Applicable bankruptcy
laws often allow these airlines to terminate leases early and to return our engines or aircraft without meeting the contractual
return conditions. In that case, we may not be paid the full amount, or any part, of our claims for these lease terminations. 
Alternatively, we might negotiate agreements with those airlines under which the airline continues to lease the engine or 
aircraft,  but  under  modified  lease  terms.  If  requests  for  payment  restructuring  or  rescheduling  are  made  and  granted, 
reduced or deferred rental payments may be payable over all or some part of the remaining term of the lease, although the 
terms of any revised payment schedules may be unfavorable and such payments may not be made.  In the case of an airline 
which has ceased operations entirely, in addition to the risk of nonpayment, we face the enhanced risk of deterioration or 
total loss of an engine or aircraft while it is under uncertain custody and control.  In that case, we may be required to take 
legal action to secure the return of the engine or aircraft and its records or, alternatively, to negotiate a settlement under 
which we can immediately recover the engine or aircraft and its records in exchange for waiving subsequent legal claims. 

17 

We may not be able to repossess an engine or aircraft when the lessee defaults, and even if we are able to repossess 
the engine or aircraft, we may have to expend significant funds in the repossession, remarketing and leasing of the asset. 

When a lessee defaults and such default is not cured in a timely manner we typically seek to terminate the lease and 
repossess the engine or aircraft. If a defaulting lessee contests the termination and repossession or is under court protection,
enforcement of our rights under the lease may be difficult, expensive and time-consuming. We may not realize any practical 
benefits from our legal rights and we may need to obtain consents to export the engine or aircraft. As a result, the relevant 
asset may be off-lease or not producing revenue for a prolonged period. In addition, we will incur direct costs associated 
with repossessing our engine or aircraft. These costs may include legal and similar costs, the direct costs of transporting, 
storing and insuring the engine or aircraft, and costs associated with necessary maintenance and recordkeeping to make 
the asset available for lease or sale. During this time, we will realize no revenue from the leased engine or aircraft, and we 
will continue to be obligated to pay any debt financing applicable to the asset. If an engine is installed on an airframe, the 
airframe may be owned by an aircraft lessor or other third party. Our ability to recover engines installed on airframes may 
depend on the cooperation of the airframe owner. 

Risks Related to Our Orders of New Engines 

We have committed to purchase new engines in 2019 with an aggregate value of up to $66.8 million. Our ability to 
lease  these  assets  on  favorable  terms,  if  at  all,  may  be  adversely  affected  by  risks  to  the  commercial  airline  industry 
generally.  If  we  are  unable  to  obtain  commitments  for  the  remaining  deliveries  or  otherwise  satisfy  our  contractual 
obligations to the engine manufacturers, we will be subject to several potential risks, including: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

forfeiting advance deposits, as well as incurring certain significant costs related to these commitments such as 
contractual damages and legal, accounting and financial advisory expenses; 

defaulting on any future lease commitments we may have entered into with respect to these engines, which could 
result in monetary damages and strained relationships with lessees; 

failing to realize the benefits of purchasing and leasing the engines; and 

risking harm to our business reputation, which would make it more difficult to purchase and lease engines in the 
future on agreeable terms, if at all. 

Risks Relating to Our Capital Structure 

Our future growth and profitability will depend on our ability to acquire aviation equipment and make other strategic 
investments.  As a result, our inability to obtain sufficient capital to finance these acquisitions would constrain our ability
to grow our portfolio and to increase our revenues. 

Our business is capital intensive and highly leveraged. Accordingly, our ability to successfully execute our business 
strategy and maintain our operations depends on the availability and cost of debt and equity capital. Additionally, our 
ability to borrow against our portfolio of engines, aircraft and strategic investments is dependent, in part, on the appraised 
value of such engines, aircraft and investments. If the appraised value of our portfolio declines, we may be required to 
either refrain from borrowings or reduce the principal outstanding under certain of our debt facilities.  

A  significant  increase  in  our  cost  to  acquire  engines  and  aircraft,  or  in  our  cost  of  strategic  investments,  due  to 
increased  interest  expense  or  cost  of  capital  will  make  it  more  difficult  for  us  to  make  accretive  acquisitions.  The 
disruptions may also adversely affect our ability to raise additional capital to fund our continued growth. Although we 
have adequate debt commitments from our lenders, assuming they are willing and able to meet their contractual obligation 
to lend to us, market disruptions may adversely affect our ability to raise additional equity capital to fund future growth, 
requiring us to rely on internally generated funds. This would lower our rate of capital investment. 

18 

We can give no assurance that the capital we need will be available to us on favorable terms, or at all. Our inability to 
obtain sufficient capital, or to renew or expand our credit facilities, could result in increased funding costs and would limit
our ability to: 

(cid:120) meet the terms and maturities of our existing and future debt facilities; 

(cid:120)

(cid:120)

(cid:120)

add new equipment to our portfolio; 

fund our working capital needs and maintain adequate liquidity; and 

finance other growth initiatives. 

Our financing facilities impose restrictions on our operations. 

We have, and expect to continue to have, various credit and financing arrangements with third parties. These financing 
arrangements are secured by all or substantially all of our assets. Our existing credit and financing arrangements require 
us to meet certain financial condition tests. Our revolving credit facility prohibits our purchasing or redeeming stock, or 
declaring or paying dividends on shares of any class or series of our common or preferred stock if an event of default under 
such facility has or will occur and remains uncured. The agreements governing our debt, including the issuance of notes 
by WEST II, WEST III and WEST IV, also include restrictive financial covenants. A breach of those and other covenants 
could, unless waived or amended by our creditors, result in a cross-default to other indebtedness and an acceleration of all 
or substantially all of our debt. We have obtained such waivers and amendments to our financing agreements in the past, 
but we cannot provide any assurance that we will receive such waivers or amendments in the future if we require them. If 
our outstanding debt is accelerated at any time, we likely would have little or no cash or other assets available after payment
of our debts, which could cause the value or market price of our outstanding equity securities to decline significantly and 
we would have few, if any, assets available for distributions to our equity holders in liquidation. 

We are exposed to interest rate risk on our leases, which could have a negative impact on our margins. 

We are affected by fluctuations in interest rates. Our lease rates are generally fixed, and a portion of our debt bears 
variable rate interest based on one-month LIBOR, so changes in interest rates directly affect our lease margins. From time 
to time, we seek to reduce our interest rate volatility and uncertainty through hedging with interest rate derivative contracts
with respect to a portion of our debt. Our lease margins, as well as our earnings and cash flows may be adversely affected 
by increases in interest rates. To the extent we do not have hedges or other derivatives in place or if our hedges or other 
derivatives do not mitigate our interest rate exposure from an economic standpoint, we would be adversely affected by 
increasing interest rates. As reported by Intercontinental Exchange, the one-month LIBOR was approximately 2.50% and 
1.57% on December 31, 2018 and December 31, 2017, respectively. 

An increase in interest rates or in our borrowing margin would increase the cost of servicing our debt and could 

reduce our profitability. 

A significant portion of our outstanding debt bears interest at floating rates. As a result, to the extent we have not 
hedged  against  rising  interest  rates,  an  increase  in  the  applicable  benchmark  interest  rates  would  increase  our  cost  of 
servicing our debt and could materially and adversely affect our results of operations, financial condition, liquidity and 
cash flows. 

In addition, we regularly refinance our indebtedness. If interest rates or our borrowing margins increase between the 
time an existing financing arrangement was consummated and the time such financing arrangement is refinanced, the cost 
of servicing our debt would increase and our results of operations, financial condition, liquidity and cash flows could be 
materially and adversely affected. 

19 

We have risks in managing our portfolio of engines to meet customer needs. 

The relatively long life cycles of aircraft and jet engines can be shortened by world events, government regulation or 
customer preferences. We seek to manage these risks by trying to anticipate demand for particular engine and aircraft 
types, maintaining a portfolio mix of engines that we believe is diversified and that will have long-term value and will be 
sought by lessees in the global market for jet engines, and by selling engines and aircraft that we expect will experience 
obsolescence or declining usefulness in the foreseeable future.  

The WEST II securitization facility includes restrictions and limitations on the sale of engines in that facility including, 
among others, that (i) the net proceeds from any individual engine sale must be at least 105% of the debt allocated under 
the facility to that engine, and (ii) the aggregate appraised value of the facility’s engines sold through September 2019 
cannot exceed 20% of the total appraised value of the facility’s engines at the inception of the facility plus the value of 
capitalized modifications to the engines since then, and cannot exceed 30% thereafter. We can give no assurance that we 
can successfully manage our engine portfolio to reduce these risks. 

The WEST III securitization facility includes restrictions and limitations on the sale of assets in that facility including, 
with respect to pro forma limitations on assets subject to part-out agreements, a 15% limitation on sales prior to August 
2019 and 20% thereafter, and also, in certain situations, with respect to a 25% limit on assets sold below a specific dollar 
threshold.  

The WEST IV securitization facility includes restrictions and limitations on the sale of assets in that facility including, 
with respect to pro forma limitations on assets subject to part-out agreements, a 15% limitation on sales prior to August 
2020 and 20% thereafter, and also, in certain situations, with respect to a 25% limit on assets sold below a specific dollar 
threshold. 

Our inability to maintain sufficient liquidity could limit our operational flexibility and also impact our ability to make 

payments on our obligations as they come due. 

In  addition  to  being  capital  intensive  and  highly  leveraged,  our  business  also  requires  that  we  maintain  sufficient 
liquidity to enable us to contribute the non-financed portion of engine and aircraft purchases as well as to service our 
payment obligations to our creditors as they become due, despite the fact that the timing and amounts of payments under 
our  leases  do  not  match  the  timing  under  our  debt  service  obligations.  Our  restricted  cash  is  unavailable  for  general 
corporate purposes. Accordingly, our ability to successfully execute our business strategy and maintain our operations 
depends on our ability to continue to maintain sufficient liquidity, cash and available credit under our credit facilities. Our
liquidity could be adversely impacted if we are subjected to one or more of the following: a significant decline in lease 
revenues, a material increase in interest expense that is not matched by a corresponding increase in lease rates, a significant
increase  in operating  expenses, or  a reduction  in our  available  credit  under  our  credit facilities.  If we  do not  maintain 
sufficient liquidity, our ability to meet our payment obligations to creditors or to borrow additional funds could become 
impaired as could our ability to make dividend payments or other distributions to our equity holders. See “Management’s 
Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—Financial  Position,  Liquidity  and  Capital 
Resources.” 

RISKS RELATING TO THE COMMON STOCK TRADING PRICE 

The Company’s Common Stock trading price may be affected by numerous factors that may impose a financial risk 

on the Company’s stockholders. 

The trading price of our common stock may fluctuate due to many factors, including: 

(cid:120)

(cid:120)

(cid:120)

risks relating to our business described in this Annual Report; 

sales of our securities by a few stockholders or even a single significant stockholder; 

general economic conditions;

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

changes in accounting mandated under GAAP; 

quarterly variations in our operating results; 

our financial condition, performance and prospects; 

changes in financial estimates by us; 

the level, direction and volatility of interest rates and expectations of changes in rates; 

the market for securities similar to our common stock; and 

changes in our capital structure, including additional issuances by us of debt or equity securities. 

In addition, the U.S. stock markets have experienced price and volume volatility that has affected many companies’ 

stock prices, often for reasons unrelated to the operating performance of those companies. 

RISKS RELATING TO OUR FOREIGN OPERATIONS 

A  substantial  portion  of  our  lease  revenue  comes  from  foreign  customers,  subjecting  us  to  divergent  regulatory 

requirements. 

For the year ended December 31, 2018, 77% of our lease revenue was generated by leases to foreign customers. Such 
international leases present risks to us because certain foreign laws, regulations and judicial procedures may not be as 
protective of lessor rights as those which apply in the United States. We are also subject to risks of foreign laws that affect
the timing and access to courts and may limit our remedies when collecting lease payments and recovering assets. None 
of  our  leased engines have been  expropriated;  however, we  can give  no  assurance  that  political  instability  abroad  and 
changes in the policies of foreign nations will not present expropriation risks in the future that are not covered by insurance.

Substantially all of our leases require payments in U.S. dollars but many of our customers operate in other currencies; 

if foreign currencies devalue against the U.S. dollar, our lessees may be unable to make their payments to us. 

Substantially all of our current leases require that payments be made in U.S. dollars. If the currency that our lessees 
typically use in operating their businesses devalues against the U.S. dollar, those lessees could encounter difficulties in 
making  payments  in  U.S.  dollars.  Furthermore,  many  foreign  countries  have  currency  and  exchange  laws  regulating 
international payments that may impede or prevent payments from being paid to us in U.S. dollars. Future leases may 
provide  for  payments  to  be  made  in  euros  or  other  foreign  currencies.  Any  change  in  the  currency  exchange  rate  that 
reduces the amount of U.S. dollars obtained by us upon conversion of future lease payments denominated in euros or other 
foreign currencies, may, if not appropriately hedged by us, have a material adverse effect on us and increase the volatility 
of our earnings. If payments on our leases are made in foreign currency, our risks and hedging costs will increase. 

We operate globally and are affected by our customers’ local and regional economic and other risks. 

We believe that our customers’ growth and financial condition are driven by economic growth in their service areas. 
The largest portion of our lease revenues come from Europe. European airline operations are among the most heavily 
regulated in the world. At the same time, low-cost carriers have exerted substantial competitive and financial pressure on 
major European airlines. Low-cost carriers are having similar effects in North America and elsewhere. 

Our operations may also be affected by political or economic instability in the areas where we have customers. 

21 

We may not be able to enforce our rights as a creditor if a lessee files for bankruptcy outside of the United States. 

When a debtor seeks protection under the United States Bankruptcy Code, creditors are automatically stayed from 
enforcing their rights. In the case of United States-certificated airlines, Section 1110 of the Bankruptcy Code provides 
certain relief to lessors of aircraft equipment. Section 1110 has been the subject of significant litigation and we can give 
no assurance that Section 1110 will protect our investment in aircraft or engines in the event of a lessee’s bankruptcy. In 
addition, Section 1110 does not apply to lessees located outside of the United States and applicable foreign laws may not 
provide comparable protection. 

Liens on our engines or aircraft could exceed the value of such assets, which could negatively affect our ability to 

repossess, lease or sell a particular engine or aircraft. 

Liens that secure the payment of repairers’ charges or other liens may, depending on the jurisdiction, attach to engines 
and aircraft. Engines also may be installed on airframes to which liens unrelated to the engines have attached. These liens 
may secure substantial sums that may, in certain jurisdictions or for limited types of liens, exceed the value of the particular
engine or aircraft to which the liens have attached. In some jurisdictions, a lien may give the holder the right to detain or, 
in limited cases, sell or cause the forfeiture of the engine or aircraft. Such liens may have priority over our interest as well
as our creditors’ interest in the engines or aircraft, either because they have such priority under applicable local law or 
because our creditors’ security interests are not filed in jurisdictions outside the United States. These liens and lien holders
could impair our ability to repossess and lease or sell the engines or aircraft. We cannot give assurance that our lessees 
will comply with their obligations to discharge third-party liens on our assets. If they do not, we may, in the future, find it
necessary to pay the claims secured by such liens to repossess such assets. 

In certain countries, an engine affixed to an aircraft may become an accession to the aircraft and we may not be able 

to exercise our ownership rights over the engine. 

In some jurisdictions, an engine affixed to an aircraft may become an accession to the aircraft, so that the ownership 
rights of the owner of the aircraft supersede the ownership rights of the owner of the engine. If an aircraft is security for 
the owner’s obligations to a third-party, the security interest in the aircraft may supersede our rights as owner of the engine.
This legal principle could limit our ability to repossess an engine in the event of a lessee bankruptcy or lease default while 
the aircraft with the engine installed remains in such a jurisdiction. We may suffer a loss if we are not able to repossess 
engines leased to lessees in these jurisdictions. 

Changes to trade policy, tariff, sanction and import/export regulations may have a material adverse effect on our 

business, financial condition and results of operations. 

Changes  in  U.S.  or  international,  political,  regulatory  and  economic  conditions  or  in  laws  and  policies  governing 
foreign trade and investment in the territories or countries where we currently conduct our business, could adversely affect 
our business. The executive branch of the United States government has instituted or proposed changes in trade policies 
that include the negotiation or termination of trade agreements, the imposition of higher tariffs on imports into the U.S., 
economic sanctions on corporations or countries, and other government regulations affecting trade between the U.S. and 
other countries that will affect the manner in which we conduct our business. Trading partners of the United States have 
also implemented and threatened to implement retaliatory tariffs and/or other impediments to trade. 

As a result of new or threatened tariffs, sanctions and/or impediments to trade, both from the United States and other 
countries, there may be greater restrictions and economic disincentives on international trade. The new or threatened tariffs, 
sanctions  and  other  changes  in  trade  policy  could  trigger  retaliatory  actions  by  affected  countries,  and  certain  foreign 
governments have instituted or are considering imposing tariffs and/or economic sanctions on certain U.S. goods. We do 
a significant amount of business that would be impacted by changes to the trade policies of the U.S. and foreign countries 
(including governmental action related to tariffs, international trade agreements, or economic sanctions). Such changes 
have the potential to adversely impact the U.S. economy or certain sectors thereof, our industry and the global demand for 
our products and services, and as a result, could have an adverse effect on our business, financial condition and results of 
operations. 

22 

Uncertainty regarding Brexit and the outcome of future arrangements between the European Union and the United 

Kingdom may adversely affect our business. 

On June 23, 2016, the U.K. voted in favor of a referendum to leave the European Union, commonly referred to as 
“Brexit”. On March 29, 2017, the U.K. invoked Article 50 of the Lisbon Treaty, which triggered a two-year period (subject 
to extension by unanimous approval of the European Union member states) for the U.K. and European Union to negotiate 
the  terms  of  the  U.K.’s  withdrawal.  The  U.K.  and  European  Union  negotiated  and  proposed  a  form  of  withdrawal 
agreement;  however,  the  U.K.  parliament  rejected  the  proposed  agreement  on  January  15,  2019,  and  any  alternative 
withdrawal agreement remains subject to approval by the U.K. parliament and European Union member states. The nature 
of the arrangements between the U.K. and the European Union are yet to be determined and difficult to predict. Absent 
any changes to the current timeline, the U.K. will leave the European Union on March 29, 2019. Uncertainty regarding the 
outcome of any withdrawal agreement and negotiations between the U.K. and European Union means there is a risk that 
these arrangements may not be ready for implementation by the end of March 2019, or that the U.K. leaves the European 
Union without an agreement in place (commonly referred to as a “no-deal Brexit”). Ongoing uncertainty regarding such 
arrangements may continue for a significant period of time (especially if a no-deal Brexit occurs) and could adversely 
affect European and worldwide economic and market conditions, contribute to instability in global financial and foreign 
exchange markets, and introduce significant legal uncertainty and potentially divergent national laws and regulations. 

We have a presence in certain European Union countries, including Ireland, England, Wales and France. During 2018, 
we derived approximately 77% of our core leasing revenue from international business. The consequences of Brexit could 
introduce significant uncertainties into global financial markets and adversely impact the markets in which we and our 
customers operate.

RISKS RELATED TO OUR SMALL SIZE AND CORPORATE STRUCTURE 

Intense competition in our industry, particularly with major companies with substantially greater financial, personnel, 

marketing and other resources, could cause our revenues and business to suffer.

The engine and aircraft leasing industry is highly competitive and global. Our primary competitors include GE Capital 
Aviation  Services,  Shannon  Engine  Support  Ltd.,  Pratt &Whitney,  Rolls-Royce  Partners  Finance  and  Engine  Lease 
Finance Corporation. 

Our primary competitors generally have significantly greater financial, personnel and other resources, as well as a 
physical presence in more locations, than we do. In addition, competing engine lessors may have lower costs of capital 
and may provide financial or technical services or other inducements to customers, including the ability to sell or lease 
aircraft, offer maintenance and repair services or provide other forms of financing that we do not provide. We cannot give 
assurance that we will be able to compete effectively or that competitive pressures will not adversely affect us. 

There is no organized market for the spare engines or the aircraft we purchase. Typically, we purchase engines and 
aircraft  from  commercial  aircraft  operators,  engine  manufacturers,  MROs  and  other  suppliers.  We  rely  on  our 
representatives,  advertisements  and  reputation  to  generate  opportunities  to  purchase  and  sell  engines  and  aircraft.  The 
market for purchasing engine and aircraft portfolios is highly competitive, generally involving an auction bidding process. 
We can give no assurance that engines and aircraft will continue to be available to us on acceptable terms and in the types 
and  quantities  we  seek  consistent  with  the  diversification  requirements  of  our  debt  facilities  and  our  portfolio 
diversification goals. 

Substantially all of our assets are pledged to our creditors.

Substantially all of our assets are pledged to secure our obligations to creditors. Our revolving credit banks have a lien 
on all of our assets, including our equity in WEST II, WEST III and WEST IV. Due to WEST II’s, WEST III’s and WEST 
IV’s bankruptcy remote structure, that equity is subject to the prior payments of WEST II’s, WEST III’s and WEST IV’s 
debt and other obligations. Therefore, our rights and the rights of our creditors to participate in any distribution of the 
assets of WEST II, WEST III and WEST IV upon liquidation, reorganization, dissolution or winding up will be subject to 

23 

the prior claims of WEST II’s, WEST III’s and WEST IV’s creditors. Similarly, the rights of our shareholders are subject 
to satisfaction of the claims of our lenders and other creditors. 

We may be unable to manage the expansion of our operations.

We  can  give  no  assurance  that  we  will  be  able  to  manage  effectively  the  current  and  potential  expansion  of  our 
operations, or that if we are successful expanding our operations that our systems, procedures or controls will be adequate 
to  support  our  operations,  in  which  event  our  business,  financial  condition,  results  and  cash  flows  could  be  adversely 
affected.

Any acquisition or expansion involves various risks, which may include some or all of the following: 

(cid:120)

(cid:120)

(cid:120)

(cid:120)

(cid:120)

incurring or assuming additional debt; 

diversion of management’s time and attention from ongoing business operations; 

future charges to earnings related to the possible impairment of goodwill and the write down of other intangible 
assets;

risks of unknown or contingent liabilities; 

difficulties in the assimilation of operations, services, products and personnel; 

unanticipated costs and delays; 

risk that the acquired business does not perform consistently with our growth and profitability expectations; 

risk  that  growth  will  strain  our  infrastructure,  staff,  internal  controls  and  management,  which  may  require 
additional personnel, time and expenditures; and 

potential loss of key employees and customers. 

Any of the above factors could have a material adverse effect on us. 

Compliance with the regulatory requirements imposed on us as a public company results in significant costs that may 

have an adverse effect on our results.

As a public company, we are subject to various regulatory requirements including, but not limited to, compliance with 
the  Sarbanes-Oxley  Act  of  2002  and  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  of  2010. 
Compliance with these regulations results in significant additional costs to us both directly, through increased audit and 
consulting fees, and indirectly, through the time required by our limited resources to address such regulations. We have 
complied with Section 404a of the Sarbanes-Oxley Act since December 31, 2007, completing our annual assessment of 
internal controls over financial reporting. We have complied with Section 404b of the Sarbanes-Oxley Act since December 
31, 2009, and our independent registered public accounting firm audits our internal controls over financial reporting. Such 
compliance requires us to incur additional costs on audit and consulting fees and requires additional management time that 
may adversely affect our results of operations and cash flows. 

We  are  subject  to  governmental  regulation  and  our  failure  to  comply  with  these  regulations  could  cause  the 
government to withdraw or revoke our authorizations and approvals to do business and could subject us to penalties and 
sanctions that could harm our business. 

Governmental  agencies  throughout  the  world,  including  the  FAA,  highly  regulate  the  manufacture,  repair  and 
operation of all aircraft operated in the United States and equivalent regulatory agencies in other countries, such as the 
EASA in Europe, regulate aircraft operated in those countries. We include, with the aircraft, engines and related parts that 

24 

we purchase, lease and sell to our customers, documentation certifying that each part complies with applicable regulatory 
requirements and meets applicable standards of airworthiness established by the FAA or the equivalent regulatory agencies 
in other countries. Specific regulations vary from country to country, although regulatory requirements in other countries 
are generally satisfied by compliance with FAA requirements. With respect to a particular engine or engine component, 
we utilize FAA and/or EASA certified repair stations to repair and certify engines and components to ensure marketability. 
The  revocation  or  suspension  of  any  of  our  material  authorizations  or  approvals  would  have  an  adverse  effect  on  our 
business, financial condition and results of operations. New and more stringent government regulations, if adopted and 
enacted, could have an adverse effect on our business, financial condition and results of operations. In addition, certain 
product sales to foreign countries require approval or licensing from the U.S. government.  Denial of export licenses could 
reduce our sales to those countries and could have a material adverse effect on our business. 

We are effectively controlled by one principal stockholder, who has the power to contest the outcome of most matters 
submitted to the stockholders for approval and to affect our stock prices adversely if he were to sell substantial amounts 
of his common stock. 

Charles  F.  Willis,  IV  is  the  founder  of  WLFC,  has  served  as  Chief  Executive  Officer  and  a  Director  since  our 
incorporation in 1985, served as President until July 2011, and has served as Chairman of the Board of Directors since 
1996. Mr. Willis has over 45 years of experience in the aviation industry which includes serving as President of Willis 
Lease’s  predecessor,  Charles F.  Willis  Company,  which  purchased,  financed  and  sold  a  variety  of  large  commercial 
transport aircraft and provided consulting services to the aviation industry, Assistant Vice President of Sales at Seaboard 
World Airlines, a freight carrier, and various positions at Alaska Airlines, including positions in the flight operations, sales
and marketing departments. As our founder and Chief Executive Officer, Mr. Willis brings to the Board significant senior 
leadership, sales and marketing, industry, technical and global experience, as well as a deep institutional knowledge of the 
Company, its operations and customer relations.

As of December 31, 2018, Mr. Willis beneficially owned or had the ability to direct the voting of 2,820,480 shares of 
our common stock, representing approximately 45% of the outstanding shares of our common stock. As a result, Mr. Willis 
effectively controls us and has the power to contest the outcome of substantially all matters submitted to our stockholders 
for approval, including the election of our board of directors. In addition, future sales by Mr. Willis of substantial amounts 
of our common stock, or the potential for such sales, could adversely affect the prevailing market price of our common 
stock.

Our business might suffer if we were to lose the services of certain key employees.

Our  business  operations  depend  upon  our  key  employees,  including  our  executive  officers.  Loss  of  any  of  these 
employees,  particularly  our  Chief  Executive  Officer,  could  have  a  material  adverse  effect  on  our  business  as  our  key 
employees have knowledge of our industry and customers and would be difficult to replace. 

We are the servicer and administrative agent for the WEST II, WEST III and WEST IV facilities and our cash flows 

would be materially and adversely affected if we were removed from these positions.

We are the servicer and administrative agent with respect to engines in the WEST II, WEST III and WEST IV facilities. 
We receive monthly fees of 11.5% as servicer (3.5% of which is subordinated in the cases of WEST III and WEST IV) 
and 2.0% as administrative agent of the aggregate net rents actually received by WEST II, WEST III and WEST IV on 
their  engines. We  may  be removed  as  servicer  and or  administrative  agent of  our WEST II, WEST III  and WEST  IV 
facilities, by an affirmative vote of a requisite number of the WEST II, WEST III and WEST IV note holders.  Such vote 
could happen upon the occurrence of certain specified events as outlined in the WEST II, WEST III and WEST IV servicing 
and administrative agency agreements. 

As of December 31, 2018, we were in compliance with the financial covenants set forth in the WEST II, WEST III 
and WEST IV servicing and administrative agency agreements. There can be no assurance that we will be in compliance 
with these covenants in the future or will not otherwise be terminated as service or administrative agent for the WEST II, 
WEST III and WEST IV facilities. If we are removed from such role with those facilities, our expenses would increase as 
our variable  interest  entities  (“VIE’s”) WEST  II, WEST  III  and WEST IV, would have  to  hire  an outside  provider  to 

25 

replace the servicer and administrative agent functions, and we would be materially and adversely affected. Consequently, 
our business, financial condition, results of operations and cash flows would be adversely affected. 

Provisions in Delaware law and our charter and bylaws might prevent or delay a change of control.

Certain provisions of law, our amended certificate of incorporation, bylaws and amended rights agreement could make 
the following more difficult: (1) an acquisition of us by means of a tender offer, a proxy contest or otherwise, and (2) the 
removal of incumbent officers and directors. 

Our board of directors has authorized the issuance of shares of 6.5% Series A Preferred Stock and 6.5% Series A-2 
Preferred Stock, by us and to Development Bank of Japan Inc. (“DBJ”) with American Stock Transfer and Trust Company, 
serving as rights agent. The rights agreement could make it more difficult to proceed with and tend to discourage a merger, 
tender offer or proxy contest. Our amended certificate of incorporation also provides that stockholder action can be taken 
only at an annual or special meeting of stockholders and may not be taken by written consent and, in certain circumstances 
relating to acquisitions or other changes in control, requires an 80% supermajority vote of all outstanding shares of our 
common stock. Our bylaws also limit the ability of stockholders to raise matters at a meeting of stockholders without 
giving advance notice. 

ITEM 2. PROPERTIES 

Our principal offices are located in Coconut Creek, Florida where we own 26,500 square feet of office and warehouse 
space. We also own 30,000 square feet of office and warehouse space in Bridgend, Wales, UK. We sub-lease 7,124 square 
feet of office and warehouse space for our operations in San Diego, California. We lease 30,000 square feet of office and 
warehouse  space  in  Boynton  Beach,  Florida  and  5,952  square  feet  of  office  space  in  Dublin,  Ireland.    We  also  lease 
facilities for sales and operations in Larkspur, CA; West Palm Beach, FL; London, UK; Shanghai, China; Singapore; and 
Blagnac, France. 

The Company’s Leasing and Related Operations segment conducts business in all of the properties above. The Spare 

Parts segment primarily conducts business in the Boynton Beach, FL and Coconut Creek, FL facilities.

We have not made any dividend payments to our common shareholders since our inception as all available cash has 
been utilized for the business. We have no intention of paying dividends on our common stock in the foreseeable future. 
In addition, certain of our debt facilities contain negative covenants which, in certain situations, prohibit us from paying 
any  dividends  or  making  distributions  of  any  kind  with  respect  to  our  common  stock.  The  Series  A-1  and  Series  A-2 
Preferred Stock carry a quarterly dividend at the rate per annum of 6.5% per share, with a $20.00 liquidation preference 
per share.

The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted on May 24, 2007. Under this 2007 Plan, a total of 
2,800,000  shares  are  authorized  for  stock  based  compensation  available  in  the  form  of  either  restricted  stock  awards 
(“RSA’s”) or stock options. The RSA’s are subject to service-based vesting, typically between one and four years, where 
a specific period of continued employment must pass before an award vests. The expense associated with these awards is 
recognized on a straight-line basis over the respective vesting period, with forfeitures accounted for as they occur. For any 
vesting  tranche  of  an  award,  the  cumulative  amount  of  compensation  cost  recognized  is  equal  to  the  portion  of  the 
grant-date fair value of the award tranche that is actually vested at that date. There are no stock options outstanding under 
the 2007 Plan.  

The 2018 Stock Incentive Plan (the “2018 Plan”) was adopted on May 24, 2018. Under this 2018 Plan, a total of 
800,000 shares are authorized for stock based compensation, plus the number of shares remaining under the 2007 Plan and 
any future forfeited awards under the 2007 and 2018 Plans, in the form of RSA’s. The RSA’s are subject to service-based 
vesting, typically between one and four years, where a specific period of continued employment must pass before an award 
vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, 
with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation 
cost recognized is equal to the portion of the grant-date fair value of the award tranche that is actually vested at that date.

As of December 31, 2018, the Company has granted 2,885,914 RSA’s under the 2007 Plan. Of this amount, 176,644 
shares were cancelled and returned to the pool of shares which could be granted under the 2018 Plan resulting in a net

number of 890,730 shares available for future issuance. The fair value of the RSA’s equaled the stock price at the grant 
date.  

As of December 31, 2018, the Company has not granted RSA’s under the 2018 Plan. 

On September 27, 2012, the Company announced that its Board of Directors authorized a plan to repurchase up to 
$100.0  million  of  its  common  stock  over  the  next  5  years.  Shares  repurchased  are  immediately  retired.  The  Board  of 
Directors reaffirmed the repurchase plan in 2016 and extended the plan to December 31, 2018.  During 2018, the Company 
repurchased 471,595 shares totaling $16.2 million under our authorized plan. As of December 31, 2018, the total number 
of common shares outstanding was approximately 6.2 million.  

Effective as of December 31, 2018, the Board of Directors approved the renewal of the repurchase plan extending the 
plan through December 31, 2020 and amending the plan to allow for repurchases of up to $60 million of the Company’s 
common stock until such date. 

Common  stock  repurchases,  under  our  authorized  plan,  in  the  fourth  quarter  ended  December  31,  2018  were  as

(1) Effective January 1, 2018, the Company adopted Accounting Standards Codification (“ASC “) 606 – Revenue from Contracts with Customers and 
has identified the transfer of engines and airframes from the lease portfolio to the Spare Parts segment for part out as sales to customers in accordance 
with the ordinary operations of our Spare Parts reportable segment. As such, the Company presents the sale of these assets on a gross basis and 
have reclassified the gross revenue on sale to the Spare parts and equipment sales line item from the net gain (loss) presentation within the Gain on 
sale of leased equipment line item. 

(2) The Company adopted ASC 606 on January 1, 2018, using the modified retrospective approach applied only to contracts not completed as of the 
date of adoption, with no restatement of comparative periods. Therefore, the comparative information has not been adjusted and continues to be

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 

OF OPERATIONS

OVERVIEW 

Forward-Looking  Statements.  This  Annual  Report  on  Form 10-K  includes  forward-looking  statements  within  the 
meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact, 
including statements regarding prospects or future results of operations or financial position, made in this Annual Report 
on  Form 10-K  are  forward-looking.  We  use  words  such  as  anticipates,  believes,  expects,  future,  intends,  and  similar 

29 

 
 
 
    
    
    
     
    
  
  
  
  
expressions  to  identify  forward-looking  statements.  Forward-looking  statements  reflect  management’s  current 
expectations and are inherently uncertain. Actual results could differ materially for a variety of reasons, including, among 
others: the effects on the airline industry and the global economy of events such as terrorist activity, changes in oil prices 
and  other  disruptions  to  the  world  markets;  trends  in  the  airline  industry  and  our  ability  to  capitalize  on  those  trends, 
including growth rates of markets and other economic factors; risks associated with owning and leasing jet engines and 
aircraft; our ability to successfully negotiate equipment purchases, sales and leases, to collect outstanding amounts due 
and to control costs and expenses; changes in interest rates and availability of capital, both to us and our customers; our 
ability  to  continue  to  meet  the  changing  customer  demands;  regulatory  changes  affecting  airline  operations,  aircraft 
maintenance, accounting standards and taxes; and the market value of engines and other assets in our portfolio. These risks 
and uncertainties, as well as other risks and uncertainties that could cause our actual results to differ significantly from 
management’s  expectations,  are  described  in  greater  detail  in  Item 1A  “Risk  Factors”  of  Part I  which,  along  with  the 
previous discussion, describes some, but not all, of the factors that could cause actual results to differ significantly from 
management’s expectations. 

General.  Our  core  business  is  acquiring  and  leasing commercial  aircraft  and  aircraft  engines  and  related  aircraft 
equipment pursuant to operating leases, all of which we sometimes refer to as “equipment.” As of December 31, 2018, all 
of  our  leases  were  operating  leases.  As  of  December  31,  2018,  we  had  81  lessees  in  47  countries.  Our  portfolio  is 
continually changing due to acquisitions and sales. As of December 31, 2018, our lease portfolio consisted of 244 engines, 
17 aircraft and 10 other leased parts and equipment with an aggregate net book value of $1,673.1 million. As of December 
31, 2018, we also managed 440 engines and related equipment on behalf of other parties.   

In 2013 we launched Willis Aero, a wholly-owned subsidiary, whose primary focus is the sale of aircraft engine parts 

and materials through the acquisition or consignment of aircraft and engines.

In 2016 we purchased, through our wholly owned subsidiary Willis Asset Management, the business and assets of 

TES. TES was the engine management and consulting business of the TES Aviation Group.  

In 2011 we entered into an agreement with Mitsui & Co., Ltd. to participate in a joint venture formed as a Dublin-
based Irish limited company —WMES for the purpose of acquiring and leasing jet engines. Each partner holds a fifty 
percent interest in the joint venture. WMES owns a lease portfolio of 32 engines and one aircraft with a net book value of 
$234.8 million at December 31, 2018. Our investment in the joint venture is $34.2 million as of December 31, 2018. 

In 2014 we entered into an agreement with CASC to participate in CASC Willis, a new joint venture based in Shanghai, 
China. Each partner holds a fifty percent interest in the joint venture. The company acquires and leases jet engines to 
Chinese airlines and concentrates on meeting the fast growing demand for leased commercial aircraft engines and aviation 
assets in the People’s Republic of China. During 2016, CASC was reorganized, with portions of its partnership interest in 
CASC  Willis  being  transferred  to  three  Chinese  airlines  and  another  government-owned  entity.  The  2016  CASC 
reorganization resulted in no voting structure change to the joint venture. CASC Willis owned a lease portfolio of 4 engines 
with a net book value of $51.9 million as of December 31, 2018. Our investment in the joint venture is $13.8 million as of 
December 31, 2018.  

We actively manage our portfolio and structure our leases to maximize the residual values of our leased assets. Our 
leasing business focuses on popular Stage IV commercial jet engines manufactured by CFMI, General Electric, Pratt & 
Whitney,  Rolls  Royce  and  International  Aero  Engines.  These  engines  are  the  most  widely  used  engines  in  the  world, 
powering Airbus, Boeing, Bombardier and Embraer aircraft. 

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the 
reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. 
On  an  ongoing  basis,  we  evaluate  our  estimates,  including  those  related  to  residual  values,  estimated  asset  lives, 
impairments  and bad  debts. We  base our  estimates  on  historical  experience  and on various  other  assumptions  that  we 
believe to be reasonable under the circumstances for making judgments about the carrying values of assets and liabilities 

30 

that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions 
or conditions. 

We believe the following critical accounting policies, grouped by our activities, affect our more significant judgments 

and estimates used in the preparation of our consolidated financial statements: 

Leasing Related Activities. Revenue from leasing of aircraft equipment is recognized as operating lease revenue on a 
straight-line basis over the terms of the applicable lease agreements. Where collection cannot be reasonably assured, for 
example, upon a lessee bankruptcy, we do not recognize revenue until cash is received. We also estimate and charge to 
income a provision for bad debts based on our experience in the business and with each specific customer and the level of 
past  due  accounts.  The  financial  condition  of  our  customers  may  deteriorate  and  result  in  actual  losses  exceeding  the 
estimated allowances. In addition, any deterioration in the financial condition of our customers may adversely affect future 
lease revenues. As of December 31, 2018, all of our engine leases are accounted for as operating leases. Under an operating 
lease, we retain title to the leased equipment, thereby retaining the potential benefit and assuming the risk of the residual 
value of the leased equipment.   

We generally depreciate engines on a straight-line basis over 15 years to a 55% residual value. Aircraft and airframes 
are generally depreciated on a straight-line basis over 13 to 20 years to a 15% to 17% residual value. Other leased parts 
and  equipment  are  generally  depreciated  on  a  straight-line  basis  over  14  to  15  years  to  a  25%  residual  value.  Major 
overhauls paid for by us, which improve functionality or extend the original useful life, are capitalized and depreciated 
over  the  shorter  of  the  estimated  period  to  the  next  overhaul  (“deferral  method”)  or  the  remaining  useful  life  of  the 
equipment. We do not accrue for planned major maintenance. For equipment which is unlikely to be repaired at the end of 
its current expected life, and is likely to be disassembled upon lease termination, we depreciate the equipment over its 
estimated life to a residual value based on an estimate of the wholesale value of the parts after disassembly. As of December 
31, 2018, 34 engines having a net book value of $46.3 million were depreciated under this policy with estimated useful 
lives ranging from 1 to 80 months. 

Asset Valuation. Long-lived assets and certain identifiable intangibles to be held and used are reviewed for impairment 
whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable, and 
long-lived assets and certain identifiable intangibles to be disposed of are reported at the lower of carrying amount or fair 
value less cost to sell. 

On a quarterly basis, management monitors the lease portfolio for events which may indicate that a particular asset 
may  need  to  be  evaluated  for  potential  impairment.  These  events  may  include  a  decision  to  part-out  or  sell  an  asset, 
knowledge of specific damage to an asset, or supply/demand events which may impact the Company’s ability to lease an 
asset in the future. On an annual basis, even absent any such ‘triggering event’, we evaluate the carrying value of the assets 
in our lease portfolio to determine if any impairment exists. 

Impairment may be identified by several factors, including, comparison of estimated sales proceeds or undiscounted 
forecasted cash flows over the life of the asset with the asset’s book value. If the forecasted undiscounted cash flows are 
less than the book value, the asset is written down to its fair value. When evaluating for impairment, we group assets at 
the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. 
In our portfolio, this is at the individual asset level (e.g., engine or aircraft), as each asset generates its own stream of cash
flows, including lease rents, maintenance reserves and repair costs.  

We must make assumptions which underlie the most significant and subjective estimates in determining whether any 

impairment exists.  Those estimates, and the underlying assumptions, are as follows: 

(cid:120)

(cid:120)

Fair value – we determine fair value by reference to independent appraisals, quoted market prices (e.g., an offer 
to purchase) and other factors such as current data from airlines, engine manufacturers and MRO providers as 
well as specific market sales and repair cost data. 

Future  cash  flows  –  when  evaluating  the  future  cash  flows  that  an  asset  will  generate,  we  make  assumptions 
regarding  the  lease  market  for  specific  engine  models,  including  estimates  of  market  lease  rates  and  future 

31 

demand. These assumptions are based upon lease rates that we are obtaining in the current market as well as our 
expectation of future demand for the specific engine/aircraft model.   

If the undiscounted forecasted cash flows and fair value of our long-lived assets decrease in the future we may incur 

impairment charges. 

Management continuously monitors the aviation industry and evaluates any trends, events or uncertainties involving 
airlines, individual aircraft and engine models, as well as the engine leasing and sale market which would materially affect 
the methodology or assumptions employed by WLFC. We do not consider there to be any trends, events or uncertainties 
that currently exist or that are reasonably likely to occur that would materially affect our methodology or assumptions. 
However, should any arise, we will adjust our methodology and our disclosure accordingly. 

Spare parts inventory is stated at lower of cost or net realizable value. An impairment charge for excess or inactive 
inventory is recorded based upon an analysis that considers current inventory levels, historical usage patterns, future sales 
expectations and salvage value. 

Accounting for Maintenance Expenditures and Maintenance Reserves. Use fees received are recognized in revenue as 
maintenance reserve revenue if they are not reimbursable to the lessee. Use fees that are reimbursable are recorded as a 
maintenance reserve liability until they are reimbursed to the lessee, the lease terminates, or the obligation to reimburse 
the lessee for such reserves ceases to exist, at which time they are recognized in revenue as maintenance reserve revenue. 
Our  expenditures  for  maintenance  are  expensed  as  incurred.  Expenditures  that  meet  the  criteria  for  capitalization  are 
recorded as an addition to equipment recorded on the balance sheet.

The most recent adopted and to be adopted accounting pronouncements are described in Note 1(w) to our Consolidated 

financial statements included in this Annual Report on Form 10-K.

Lease  Rent  Revenue.  Our  lease  rent  revenue  for  the  year  ended  December  31,  2018  increased  by  34.7%  over  the 
comparable period in 2017. Lease rent revenue consists of rental income from long-term and short-term engine leases, 
aircraft leases, and other leased parts and equipment. The increase is primarily driven by an increase in lease rates and

increased net book value of the leased assets. The aggregate net book value of equipment held for lease at December 31, 
2018 and 2017, was $1,673.1 million and $1,342.6 million, respectively, an increase of 24.6%. During the year ended 
December 31, 2018, 38 engines and 7 aircraft were added to our lease portfolio at a total cost of $421.9 million (including 
capitalized costs). During the year ended December 31, 2017, 30 engines and 10 aircraft were added to our lease portfolio 
at a total cost of $336.1 million (including capitalized costs). 

Maintenance Reserve Revenue. Our maintenance reserve revenue for the year ended December 31, 2018 increased 
8.5% to $87.0 million from $80.2 million for the year ended December 31, 2017. The $6.8 million increase is primarily 
related to the increase in engines out on lease with “non-reimbursable” usage fees, generating $63.7 million of short term 
maintenance revenues compared to $44.2 million of short term maintenance revenues generated in the comparable prior 
period. Long term maintenance revenue decreased to $23.3 million for the year ended December 31, 2018 compared to 
$36.0 million in 2017 as a result of fewer long-term leases coming to an end during 2018 as compared to the prior year. 

Spare Parts and Equipment Sales. Spare parts and equipment sales for the year ended December 31, 2018 increased 
by $19.7 million to $71.1 million compared to $51.4 million in 2017. Spare parts sales for the year ended December 31, 
2018 were $50.0 million compared to $29.1 million in 2017. Equipment sales for the year ended December 31, 2018 were 
$21.1 million for the sale of two engines compared to $22.3 million for the sale of six airframes in the comparable period 
of 2017. As a result of the implementation of ASC 606, the Company reclassified sales of engines from its leasing portfolio 
by its spare parts segment from net Gain on sale of leased equipment to Spare parts and equipment sales and Cost of spare 
parts and equipment sales. Additionally, as a result of this implementation, the Company recorded these sales on a gross 
basis in 2018 which impacted Spare parts and equipment sales by an additional $16.4 million. 

Gain on Sale of Leased Equipment. During the year ended December 31, 2018, we sold 14 engines, six aircraft, one 
airframe  and  other  related  equipment  from  the  lease  portfolio  for  a  net  gain  of  $6.9  million.  During  the  year  ended 
December 31, 2017, we sold 11 engines and other related equipment from the lease portfolio for a net gain of $4.9 million. 
As a result of the implementation of ASC 606, the Company reclassified sales of engines from its leasing portfolio by its 
spare parts segment from Gain on sale of leased equipment to Spare parts and equipment sales. Additionally, as a result of 
this implementation, the Company recorded these sales on a gross basis in 2018 which reduced the net Gain on sale of 
leased equipment by $0.7 million. 

Other Revenue. Other revenue consists primarily of management fee income, lease administration fees, third party 
consignment commissions, service fee revenue, and other discrete revenue items. During the year ended December 31, 
2017, Other revenue included a net gain on an insurance settlement of $1.3 million related to a leased aircraft. 

Depreciation and Amortization Expense. Depreciation and amortization expense increased $10.8 million or 16.3% to 
$76.8 million for the year ended December 31, 2018. The increase in depreciation is associated with growth in our lease 
portfolio and the related larger net book value of the lease portfolio. 

(cid:3)
Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales for the year ended December 31, 
2018 was $61.0 million, an increase of 49.4% from 2017. Cost of spare parts sales for the year ended December 31, 2018 
were $41.5 million compared to $23.5 million in 2017. Cost of equipment sales was $19.5 million and $17.3 million in the 
years ended December 31, 2018 and 2017, respectively. As a result of the implementation of ASC 606, the Company 
reclassified sales of engines from its leasing portfolio by its spare parts segment from net Gain on sale of leased equipment 
to  Spare  parts  and  equipment  sales  and  Cost  of  spare  parts  and  equipment  sales.  Additionally,  as  a  result  of  this 
implementation,  the  Company  recorded  these  sales  on  a  gross  basis  in  2018  which  impacted  Cost  of  spare  parts  and 
equipment sales by an additional $15.7 million. 

Write-down of Equipment. Write-down of equipment to their estimated fair values totaled $10.7 million for the year 
ended December 31, 2018, a decrease of $14.3 million from the $24.9 million in 2017. The $10.7 million write-down in 
2018 reflects the write-down of seven engines and seven airframe parts packages. A write-down of $21.6 million was 
recorded  due  to  the  adjustment  of  the  carrying  value  for  nine  impaired  engines  and  five  impaired  aircraft  within  the 
portfolio  to  reflect  estimated  market  value  for  the  year  ended  December  31,  2017.  The  decrease  in  write-downs  of 
equipment in 2018 reflects more engines out on long-term lease, which carry significant long term maintenance reserves, 
as compared to the prior year.

General and Administrative Expenses. General and administrative expenses increased 29.2% to $72.0 million for the 
year ended December 31, 2018 compared to $55.7 million in 2017. The increase, when compared to the prior year period, 
primarily reflects additional expenses associated with the transition of personnel to our new Coconut Creek facility, other 
transition related expenses, and increased bonus accrual due to operating performance. 

Technical  Expense.  Technical  expenses  consist  of  the  cost  of  engine  repairs,  engine  thrust  rental  fees,  outsourced 
technical  support  services,  sublease  engine  rental  expense,  engine  storage  and  freight  costs.  These  expenses  increased 
14.5% to $11.1 million for the year ended December 31, 2018, compared to $9.7 million in 2017. The increase is due 
primarily to an increase of $0.6 million in engine maintenance costs and an increase of $0.9 million in engine freight costs, 
both associated with the underlying growth of the business. 

Net Finance Costs. Net finance costs, which primarily reflects interest expense, increased 31.8% to $64.2 million in 
the year ended December 31, 2018, from $48.7 million for the year ended December 31, 2017. This increase is a result of 
higher debt obligation balances and increased borrowing cost in 2018 associated with our LIBOR based borrowings and a 
full year of interest under the WEST III notes and partial year of interest under the WEST IV notes. Debt obligations 
outstanding,  net  of  unamortized  debt  issuance  costs,  as  of  December  31,  2018  and  2017,  were  $1,337.3  million  and 
$1,085.4 million, respectively, of which $427.0 million and $501.3, respectively, was tied to one-month LIBOR. As of 
December 31, 2018 and 2017 one-month LIBOR was 2.50% and 1.57%, respectively.(cid:3)

Income Taxes. Income tax expense for the year ended December 31, 2018 increased to $13.0 million from $(26.1) 
million for the comparable period in 2017. The effective tax rate for the years ended December 31, 2018 and December 
31, 2017 was 23.2% and (72.6)%, respectively. This change was due to the Tax Cuts and Jobs Act of 2017 (the “2017 
Act”) that was signed into law making significant changes to the Internal Revenue Code, decreasing federal corporate tax 
rate  from  35%  to  21%  for  tax  years  beginning  after  December  31,  2017,  lower  forecasted  permanent  non-deductible 
expenses for executive compensation (IRS code 162(m) calculation) and changes in the proportions of revenue generated 
within and outside of California.

Lease  Rent  Revenue.  Our  lease  rent  revenue  for  the  year  ended  December  31,  2017  increased  by  8.7%  over  the 
comparable period in 2016. Lease rent revenue consists of rental income from long-term and short-term engine leases, 
aircraft leases, and other leased parts and equipment. The increase is primarily driven by an increase in lease rates and 
increased net book value of the leased assets. The aggregate net book value of equipment held for lease at December 31, 
2017 and 2016, was $1,342.6 million and $1,136.6 million, respectively, an increase of 18.1%. During the year ended 
December 31, 2017, 30 engines and 10 aircraft were added to our lease portfolio at a total cost of $336.1 million (including 
capitalized costs). During the year ended December 31, 2016, 20 engines and 1 aircraft were added to our lease portfolio 
at a total cost of $153.1 million (including capitalized costs). 

Maintenance Reserve Revenue. Our maintenance reserve revenue for the year ended December 31, 2017 increased 
40.5% to $80.2 million from $57.1 million for the year ended December 31, 2016. The $23.1 million increase is primarily 
related to the termination of nine engines coming off of long-term reimbursable leases, generating $36.0 million of long 
term maintenance revenues compared to $14.8 million of long term maintenance revenues generated in the comparable 
prior period by seven engines coming off long-term lease.

Spare Parts and Equipment Sales. Spare parts and equipment sales for the year ended December 31, 2017 increased 
by $33.6 million to $51.4 million compared to $17.8 million in 2016. Spare parts sales for the year ended December 31, 
2017 were $29.1 million compared to $14.5 million in the comparable period in 2016. Equipment sales of $22.3 million 
were for the sale of six airframes during the year ended December 31, 2017. Equipment sales of $3.3 million were for the 
sale of three airframes during the year ended December 31, 2016.  

Gain on Sale of Leased Equipment. During the year ended December 31, 2017, we sold eleven engines and other 
related equipment from the lease portfolio for a net gain of $4.9 million. During the year ended December 31, 2016, we 
sold seven engines, one airframe and other related equipment from the lease portfolio for a net gain of $3.5 million. 

Other Revenue. Our Other revenue consists primarily of management fee income, lease administration fees, third party 
consignment commissions earned by Willis Aero and other discrete revenue items. During the year ended December 31, 
2017, other revenue included a net gain on an insurance settlement of $1.3 million related to a leased aircraft, fees earned 
related to engines managed on behalf of third parties and service fee revenue earned by Willis Asset Management. During 
the year ended December 31, 2016, Other revenue included $4.0 million of security payments for aircraft upon default of 
a lessee and a $0.6 million foreign subsidy recognized in the period. The foreign subsidy was received from the People’s 
Republic of China resulting from our China subsidiary operating in the Shanghai free trade zone. 

Depreciation and Amortization Expense. Depreciation and amortization expense was relatively consistent with the 
prior year period, decreasing $0.3 million or 0.4% to $66.0 million for the year ended December 31, 2017. The slight 
decrease reflects changes in portfolio mix associated with our ongoing portfolio management efforts, partially offset by an 
increase in depreciation associated with the larger net book value of the lease portfolio. 

Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales for the year ended December 31, 
2017 was $40.8 million, an increase of 207.3% from 2016. Cost of spare parts sales for the year ended December 31, 2017 
were $23.5 million compared to $10.7 million in 2016. Gross margin on spare parts sales for 2017 was 19.0% compared 
to 24.6% for 2016 primarily due to a change in the mix of parts sold in 2017. Cost of equipment sales was $17.3 million 
and $2.4 million in the years ended December 31, 2017 and 2016, respectively.   

Write-down of Equipment. Write-down of equipment to their estimated fair values totaled $24.9 million for the year 
ended December 31, 2017, an increase of $15.4 million from the $9.5 million in 2016. This increase primarily reflects a 
write-down of $21.6 million recorded in 2017 for the adjustment of the carrying value of nine impaired engines and five 
impaired aircraft within the portfolio to reflect estimated market value.  

A write-down of $5.5 million was recorded due to the adjustment of the carrying value for six impaired engines and 
one impaired aircraft within the portfolio to reflect estimated market value for the year ended December 31, 2016. A further 
write-down of equipment totaling $2.0 million was recorded in the year ended December 31, 2016 due to a management 
decision to consign one engine for part-out and sale, in which the asset’s net book value exceeded the estimated proceeds. 
An additional write-down of $2.0 million was recorded in year ended December 31, 2016 to adjust the carrying value of 
engine parts held on consignment for which market conditions for the sale of parts has changed. 

General and Administrative Expenses. General and administrative expenses increased 16.7% to $55.7 million for the 
year ended December 31, 2017, from the prior year period in 2016, due primarily to higher personnel expense from the 
increase in headcount from the TES acquisition and increased rent and office expense. 

Technical  Expense.  Technical  expenses  consist  of  the  cost  of  engine  repairs,  engine  thrust  rental  fees,  outsourced 
technical  support  services,  sublease  engine  rental  expense,  engine  storage  and  freight  costs.  These  expenses  increased 
39.1% to $9.7 million for the year ended December 31, 2017, from 2016 due primarily to an increase of $1.7 million in 
engine  maintenance  costs  and  an  increase  of  $0.5  million  in  engine  freight  costs,  both  associated  with  the  underlying 
growth of the business. 

Net Finance Costs. Net finance costs, which primarily reflects interest expense, increased 18.0% to $48.7 million in 
the year ended December 31, 2017, from $41.3 million for the year ended December 31, 2016. This increase is a result of 
higher debt obligation balances and increased borrowing cost in 2017 associated with our LIBOR based borrowings and 

35 

our WEST III notes. Debt obligations outstanding, net of unamortized debt issuance costs, as of December 31, 2017 and 
2016, were $1,085.4 million and $900.3 million, respectively, of which $501.3 million and $339.4, respectively, was tied 
to one-month LIBOR. As of December 31, 2017 and 2016, one-month LIBOR was 1.57% and 0.77%, respectively.(cid:3)

Income Taxes. Income tax expense for the year ended December 31, 2017, decreased to $(26.1) million from $9.9 
million for the comparable period in 2016. The effective tax rate for the years ended December 31, 2017 and December 
31, 2016 were (72.6)% and 41.2%, respectively. This decrease was due to the 2017 Act that was signed into law making 
significant changes to the Internal Revenue Code, decreasing federal corporate tax rate from 35% to 21% for tax years 
beginning after December 31, 2017, lower forecasted permanent non-deductible expenses for executive compensation (IRS 
code 162(m) calculation) and changes in the proportions of revenue generated within and outside of California during the 
year ended December 31, 2017. 

  Our tax rate is subject to change based on changes in the mix of assets leased to domestic and foreign lessees, the 
proportions of revenue generated within and outside of California, the amount of executive compensation exceeding $1.0 
million as defined in IRS code 162(m) and numerous other factors, including changes in tax law. 

FINANCIAL POSITION, LIQUIDITY AND CAPITAL RESOURCES 

At December 31, 2018, the Company had $81.9 million of cash, cash equivalents and restricted cash. At December 
31, 2018, $5.8 million in cash and cash equivalents and restricted cash were held in foreign subsidiaries. We do not intend 
to repatriate the funds held in foreign subsidiaries to the United States. In the event that we decide to repatriate these funds
to the United States, we would be required to accrue and pay taxes upon the repatriation. 

We finance our growth through borrowings secured by our equipment lease portfolio. Cash of approximately $759.4 
million, $686.2 million and $149.0 million, in the years ended December 31, 2018, 2017, and 2016, respectively, was 
derived  from  this  borrowing  activity.  In  these  same  time  periods  $504.8  million,  $496.2  million  and  $114.0  million, 
respectively, was used to pay down related debt.  

Preferred Stock Dividends 

On October 11, 2016, the Company entered into a stock purchase agreement with Development Bank of Japan Inc. 
(“DBJ”), relating to the sale and issuance of an aggregate of 1,000,000 shares of the Company’s 6.5% Series A Preferred 
Stock, $0.01 par value per share (the “Series A Preferred Stock”) at a purchase price of $20.00 per share. The purchase 
and sale of the Series A Preferred Stock closed on October 14, 2016. The net proceeds to the Company after deducting 
investor fees were $19.8 million. 

On September 22, 2017, the Company entered into a second stock purchase agreement with DBJ relating to the sale 
and issuance of an aggregate of 1,500,000 shares of the Company’s 6.5% Series A-2 Preferred Stock, $0.01 par value per 
share (the “Series A-2 Preferred Stock”) at a purchase price of $20.00 per share. The purchase and sale of the Series A-2 
Preferred Stock closed on September 27, 2017. The net proceeds to the Company after deducting issuance costs were $29.7 
million. 

The Company’s Series A-1 Preferred Stock and Series A-2 Preferred Stock accrue quarterly dividends at the rate per 
annum of 6.5% per share. During the years ended December 31, 2018, 2017 and 2016, the Company paid total dividends 
of $3.3 million, $1.3 million, and nil on the Series A-1 and Series A-2 Preferred Stock, respectively. 

Cash Flows Discussion 

Cash flows provided by operating activities were $188.7 million, $137.1 million and $91.6 million in the years ended 

December 31, 2018, 2017, and 2016, respectively.  

Cash flows from operations are driven significantly by payments made under our lease agreements, which comprise 
lease revenue, security deposits and maintenance reserves, and are offset by interest expense and general and administrative 
costs. Cash received as maintenance reserve payments for some of our engines on lease are partially restricted by our debt 

36 

arrangements. The lease revenue stream, in the short-term, is at fixed rates while a portion of our debt is at variable rates. 
If interest rates increase, it is unlikely we could increase lease rates in the short term and this would cause a reduction in 
our earnings and operating cash flows. Revenue and maintenance reserves are also affected by the amount of equipment 
off  lease.  Approximately  88%  and  89%,  by  book  value,  of  our  assets  were  on-lease  as  of  December  31,  2018  and 
December 31,  2017,  respectively.  The  average  utilization  rate  for  the  year  ended  December  31,  2018  and  2017  was 
approximately 89% and 90%, respectively. If there is an increase in off-lease rates or deterioration in lease rates that are 
not offset by reductions in interest rates, there will be a negative impact on earnings and cash flows from operations. 

Distributions received from our investment in WMES were $5.7 million, $1.9 million and $1.2 million in the years 

ended December 31, 2018, 2017, and 2016, respectively. 

Cash flows used in investing activities were $380.5 million, $325.6 million and $123.2 million in the years ended 
December 31, 2018, 2017, and 2016, respectively. Our primary use of funds is for the purchase of equipment for lease and 
for sale. Purchases of equipment (including capitalized costs and prepaid deposits) totaled $441.4 million, $373.5 million 
and $173.7 million for the years ended December 31, 2018, 2017, and 2016, respectively. 

Cash flows provided by financing activities were $226.4 million, $203.4 million and $21.2 million for the years ended 
December 31, 2018, 2017, and 2016, respectively. Cash flows provided by financing activities for the year ended December 
31, 2018  primarily  reflected $759.4  million  in  proceeds  from  the  issuance  of  debt obligations, partly  offset by  $504.8 
million in principal payments and $16.1 million in share repurchases. Cash flows provided by financing activities for the 
year ended December 31, 2017 primarily reflected $686.2 million in proceeds from the issuance of debt obligations, partly 
offset by $496.2 million in principal payments and $3.5 million in share repurchases. Cash flows provided by financing 
activities for the year ended December 31, 2016 primarily reflected $149.0 million in proceeds from the issuance of debt 
obligations, partly offset by $114.0 million in principal payments and $29.0 million in share repurchases. 

Debt Obligations and Covenant Compliance 

On August 22, 2018, WEST IV, a consolidated VIE of the Company closed its offering of $373.4 million in aggregate 
principal amount of fixed rate notes (the “WEST IV Notes”). The WEST IV Notes were issued in two series, with the 
Series A Notes issued in an aggregate principal amount of $326.8 million and the Series B Notes in an aggregate principal 
amount of $46.7 million. The WEST IV Notes are secured by, among other things, WEST IV’s direct and indirect interests 
in a portfolio of 55 engines and one airframe. 

The Series A Notes have a fixed coupon of 4.75%, an expected maturity of approximately eight years and a final 
maturity  date of  September  15, 2043  and Series  B Notes  will  have  a fixed coupon of 5.44%,  an  expected  maturity  of 
approximately eight years and a final maturity date of September 15, 2043. The Series A Notes were issued at a price of 
99.99504% of par and the Series B Notes were issued at a price of 99.99853% of par. Principal and interest on the WEST 
IV Notes are payable monthly to the extent of available cash in accordance with a priority of payments included in the 
indenture. Proceeds from asset sales by WEST IV will be used, at WEST IV’s election subject to certain conditions, to 
reduce WEST IV’s debt or to acquire other engines or airframes. 

The assets of WEST IV are not available to satisfy our or our affiliates’ obligations other than the obligations specific 
to  WEST  IV.  WEST  IV  is  consolidated  for  financial  statement  presentation  purposes.  WEST  IV’s  ability  to  make 
distributions and pay dividends to the Company is subject to the prior payments of its debt and other obligations and WEST 
IV’s maintenance of adequate reserves and capital. Under WEST IV, cash is collected in a restricted account, which is 
used  to  service  the  debt  and  any  remaining  amounts,  after  debt  service  and  defined  expenses,  are  distributed  to  the 
Company.  Additionally,  a  portion  of  the  maintenance  reserve  payments  and  lease  security  deposits  are  formulaically 
accumulated  in  restricted  accounts  and  are  available  to  fund  future  maintenance  events  and  to  secure  lease  payments, 
respectively.

At December 31, 2018, debt obligations consists of loans totaling $1,337.3 million, net of unamortized issuance costs,  
payable with interest rates varying between approximately 2.6% and 6.4%. Substantially all of our assets are pledged to 
secure our obligations to creditors. For further information on our debt instruments, see Note 5 "Debt Obligations" in Part 
II, Item 8 of this Form 10-K. 

37 

Virtually  all  of  the  above  debt  requires  our  ongoing  compliance  with  the  covenants  of  each  financing,  including 
debt/equity  ratios,  minimum  tangible  net  worth  and  minimum  interest  coverage  ratios,  and  other  eligibility  criteria 
including customer and geographic concentration restrictions. Under our revolving credit facility, we can typically borrow 
up to 85% of an engine’s net book value and 65% of spare part’s net book value. Therefore we must have other available 
funds for the balance of the purchase price of any new equipment to be purchased or we will not be permitted to draw on 
our revolver. The facilities are also cross-defaulted against other facilities. If we do not comply with the covenants or 
eligibility  requirements,  we  may  not  be  permitted  to  borrow  additional  funds  and  accelerated  payments  may  become 
necessary. Additionally, much of the above debt is secured by engines and aircraft to the extent that engines or aircraft are 
sold, repayment of that portion of the debt could be required. 

At December 31, 2018, we are in compliance with the covenants specified in the revolving credit facility, including 
the Interest Coverage Ratio requirement of at least 2.25 to 1.00, and the Total Leverage Ratio requirement to remain below 
4.25 to 1.00. The Interest Coverage Ratio, as defined in the credit facility, is the ratio of: earnings before interest, taxes,
depreciation and amortization (EBITDA) and other one-time charges to consolidated interest expense.  The Total Leverage 
Ratio, as defined in the credit facility, is the ratio of total indebtedness to tangible net worth. At December 31, 2018, we 
are in compliance with the covenants specified in the WEST II, WEST III and WEST IV indentures, servicing and other 
debt related agreements. 

Contractual Obligation and Commitments 

Repayments of our gross debt obligations primarily consist of scheduled installments due under term loans and are 
funded by the use of unrestricted cash reserves and from cash flows from ongoing operations. The table below summarizes

We  have  estimated  the  interest  payments  due  under  debt  obligations  by  applying  the  interest  rates  applicable  at 
December 31, 2018 to the remaining debt, adjusted for the estimated debt repayments identified in the table above. Actual 
interest payments made will vary due to actual changes in the rates for one-month LIBOR and the total debt outstanding 
in the specified periods. 

We believe our equity base, internally generated funds and existing debt facilities are sufficient to maintain our level 
of operations through 2019. A decline in the level of internally generated funds could result if the amount of equipment 
off-lease increases, there is a decrease in availability under our existing debt facilities, or there is a significant step-up in 
borrowing costs. Such decline would impair our ability to sustain our level of operations. We continue to discuss additions 
to our capital base with our commercial and investment banks. If we are not able to access additional capital, our ability 
to continue to grow our asset base consistent with historical trends will be impaired and our future growth limited to that 
which can be funded from internally generated capital. 

MANAGEMENT OF INTEREST RATE EXPOSURE 

At December 31, 2018, $427.0 million of our borrowings were on a variable rate basis at various interest rates tied to 
one-month LIBOR. Our equipment leases are generally structured at fixed rental rates for specified terms. Increases in 
interest rates could narrow or result in a negative spread between the rental revenue we realize under our leases and the 
interest rate that we pay under our borrowings. Historically, we have entered into interest rate derivative instruments to 
mitigate  our  exposure  to  interest  rate  risk  and  not  to  speculate  or  trade  in  these  derivative  products.  During  2016,  we 

38 

 
 
 
   
       
 
 
 
 
  
  
entered  into  one  interest  rate  swap  agreement  which  has  notional  outstanding  amount  of  $100.0  million,  which  has  a 
remaining term of 28 months as of December 31, 2018. The fair value of the swap at December 31, 2018 and 2017 was 
$1.7 million and $1.1 million, respectively, representing a net asset for us.

We record derivative  instruments  at fair value  as  either  an  asset or  liability. We have used derivative instruments 
(primarily  interest  rate  swaps)  to  manage  the  risk  of  interest  rate  fluctuation.  While  substantially  all  our  derivative 
transactions are entered into for the purposes described above, hedge accounting is only applied where specific criteria 
have been met and it is practicable to do so. In order to apply hedge accounting, the transaction must be designated as a 
hedge and the hedge relationship must be highly effective. The hedging instrument’s effectiveness is assessed utilizing 
regression analysis at the inception of the hedge and on at least a quarterly basis throughout its life. All of the transactions
that we have designated as hedges are accounted for as cash flow hedges. The effective portion of the gain or loss on a 
derivative instrument designated as a cash flow hedge is reported as a component of other comprehensive income and is 
reclassified into earnings in the period during which the transaction being hedged affects earnings. The ineffective portion 
of  these  hedges  flows  through  earnings  in  the  current  period.  The  hedge  accounting  for  these  derivative  instrument 
arrangements adjusted interest expense by $(0.4) million, $0.6 million, and $25,000 for the years ended December 31, 
2018,  2017  and  2016,  respectively.  This  incremental  cost  (benefit)  for  the  swaps  effective  for  hedge  accounting  was 
included in interest expense for the respective periods.  

For any interest rate swaps that we enter into, we will be exposed to risk in the event of non-performance of the interest 

rate hedge counter-parties. We anticipate that we may hedge additional amounts of our floating rate debt in the future.

Joint Ventures 

“Other revenue” on the Consolidated Statement of Income includes management fees earned of $2.6 million, $2.4 
million and $2.1 million during the years ended December 31, 2018, 2017 and 2016, respectively, related to the servicing 
of engines for the WMES lease portfolio. During 2018, the Company sold two engines and one aircraft to WMES for $30.7 
million. During 2017, the Company sold two engines to WMES for $14.8 million.  

During 2017, the Company sold one engine to CASC Willis for $11.2 million. 

Other

$5 thousand. This transaction was approved by the Board’s independent Directors. 

During the third quarter of 2018, the Company’s Chief Executive Officer utilized the WASI spare parts warehouse to 

temporarily store personal equipment and reimbursed the Company $450 for such usage. 

39 

   
During 2018 and 2017, the Company paid approximately $44,000 and $80,000, respectively, of expenses payable to 
Mikchalk Lake, LLC, an entity in which our Chief Executive Officer retains an ownership interest.  These expenses were 
for lodging and other business related services.  These transactions were approved by the Board’s independent Directors. 

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Our  primary  market  risk  exposure  is  that  of  interest  rate  risk.  A  change  in  LIBOR  rates  would  affect  our  cost  of 
borrowing. Increases in interest rates, which may cause us to raise the implicit rates charged to our customers, could result 
in a reduction in demand for our leases. Alternatively, we may price our leases based on market rates so as to keep the fleet 
on-lease and suffer a decrease in our operating margin due to interest costs that we are unable to pass on to our customers. 
As of December 31, 2018, $427.0 million of our outstanding debt is variable rate debt. We estimate that for every one 
percent  increase  or  decrease  in  interest  rate,  the  annual  interest  expense  for  our  variable  rate  debt,  would  increase  or 
decrease $3.3 million (in 2017, $4.0 million). 

We hedge a portion of our borrowings from time to time, effectively fixing the rate of these borrowings. This hedging 
activity helps protect us against reduced margins on longer term fixed rate leases. Such hedging activities may limit our 
ability to participate in the benefits of any decrease in interest rates, but may also protect us from increases in interest rates.
Furthermore, since lease rates tend to vary with interest rate levels, it is possible that we can adjust lease rates for the effect
of change in interest rates at the termination of leases. Other financial assets and liabilities are at fixed rates. 

We  are  also  exposed  to  currency  devaluation  risk.  During  the  years  ended  December  31,  2018,  2017,  and  2016, 
respectively,  77%,  84%  and  89%  of  our  total  lease  rent  revenues  came  from  non-United  States  domiciled  lessees. 
Substantially all of our leases require payment in U.S. dollars. If these lessees’ currency devalues against the U.S. dollar, 
the lessees could potentially encounter difficulty in making their lease payments.

ITEM 9A. CONTROLS AND PROCEDURES 

(a) Evaluation of disclosure controls and procedures. Based on management’s evaluation (with the participation of 
our Chief Executive Officer (CEO) and Chief Financial Officer (CFO)), as of the end of the period covered by this report, 
our CEO and CFO have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-
15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), are effective to provide reasonable 
assurance  that  information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange  Act  is 
recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  in  SEC  rules and  forms,  and  is 
accumulated and communicated to management, including our principal executive officer and principal financial officer, 
as appropriate to allow timely decisions regarding required disclosure. 

(b) Inherent Limitations on Controls. Management, including the CEO and CFO, does not expect that our disclosure 
controls and procedures will prevent or detect all errors and fraud. Any control system, no matter how well designed and 
operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives 
will be met.  Further, no evaluation of controls can provide absolute assurance that misstatements due to errors or fraud 
will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.  The design 
of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered 
relative to their costs.

(c) Management’s  Report  on  Internal  Control  over  Financial  Reporting.  Our  management  is  responsible  for 
establishing  and  maintaining  adequate  internal  control  over  financial  reporting  as  defined  in  Rules 13a-15(f) and  15d-
15(f) under  the  Securities  Exchange  Act  of  1934.    Our  internal  control  over  financial  reporting  includes  policies  and 
procedures  that:  (a) pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  our 
transactions  and  dispositions  of  assets;  (b) provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to 
permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that our 
receipts  and  expenditures  are  being  made  only  in  accordance  with  authorizations  of  our  management  and  Board  of 
Directors; and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use 
or disposition of our assets that could have a material effect on our financial statements. Our internal control over financial
reporting is a process designed with the participation of our principal executive officer and principal financial officer or 
persons performing similar functions to provide reasonable assurance to our management and board of directors regarding 
the  reliability  of  financial  reporting  and  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounted principles. 

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018. 
In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission  (COSO) in  Internal  Control-Integrated  Framework  (2013).  Based  on  this  assessment  our  management 
believes that, as of December 31, 2018, our internal control over financial reporting is effective under those criteria. 

KPMG  LLP,  the  independent  registered  public  accounting  firm  that  audited  the  Company’s  financial  statements 
included in this Annual Report, issued an audit report on the Company’s internal control over financial reporting. KPMG’s 
audit report appears on page 49. 

(d) Changes  in  internal  control  over  financial  reporting.  There  has  been  no  change  in  our  internal  control  over 
financial reporting during our fourth fiscal quarter ended December 31, 2018 that has materially affected, or is reasonably 
likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and Board of Directors 
Willis Lease Finance Corporation: 

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting  

We have audited the accompanying consolidated balance sheets of Willis Lease Finance Corporation and subsidiaries (the 
Company)  as of  December 31, 2018  and 2017,  the  related  consolidated  statements  of income,  comprehensive  income, 
redeemable preferred stock and shareholders’ equity, and cash flows for each of the years in the three-year period ended 
December 31, 2018, and the related notes and financial statement schedules I and II (collectively, the consolidated financial 
statements). We also have audited the Company’s internal control over financial reporting as of December 31, 2018, based 
on  criteria  established  in  Internal  Control  –  Integrated  Framework (2013)  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission.   

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial
position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each 
of the years in the three-year period ended December 31, 2018, in conformity with U.S. generally accepted accounting 
principles. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2018 based on criteria established in Internal Control – Integrated Framework (2013) issued 
by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions  

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, 
included  in  the  accompanying  Item  9A,  Controls  and  Procedures.  Our  responsibility  is  to  express  an  opinion  on  the 
Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting 
based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. 
federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  and  the 
PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the  audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial  statements  are  free  of  material 
misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained 
in all material respects.  

Our  audits  of  the  consolidated  financial  statements  included  performing  procedures  to  assess  the  risks  of  material 
misstatement  of  the  consolidated  financial  statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that 
respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and 
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial 
statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control 
over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  and  testing  and  evaluating  the  design  and 
operating  effectiveness  of  internal  control  based  on  the  assessed  risk.  Our  audits  also  included  performing  such  other 
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our 
opinions. 

Definition and Limitations of Internal Control Over Financial Reporting  

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 

49 

generally accepted accounting principles. A company’s internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, 
and that receipts and expenditures of the company are being made only in accordance with authorizations of management 
and  directors  of  the  company;  and  (3) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of 
unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

WILLIS LEASE FINANCE CORPORATION
AND SUBSIDIARIES
Notes to Consolidated Financial Statements 

1. Organization and Summary of Significant Accounting Policies 

Unless the context requires otherwise, references to “WLFC”, “the Company”, “we”, “us” or “our” in this Annual 

Report on Form 10-K refer to Willis Lease Finance Corporation and its subsidiaries. 

(a)   Organization 

Willis  Lease  Finance  Corporation  with  its  subsidiaries  is  a  provider  of  aviation  services  whose  primary  focus  is 
providing  operating  leases  of  commercial  aircraft,  aircraft  engines  and  other  aircraft-related  equipment  to  air  carriers, 
manufacturers and overhaul/repair facilities worldwide. The Company also engages in the selective purchase and resale of 
commercial aircraft engines.  

Willis Aeronautical Services, Inc. (“Willis Aero”) is a wholly-owned subsidiary whose primary focus is the sale of 

aircraft engine parts and materials through the acquisition or consignment of aircraft and engines. 

In  2016,  the  Company  purchased,  through a  wholly owned  subsidiary Willis Asset Management  Limited  (“Willis 
Asset  Management”),  the  business  and  assets  of  Total  Engine  Support  Limited  (“TES”).  TES  had  been  the  engine 
management and consulting business of the TES Aviation Group. 

Willis Engine Securitization Trust II (“WEST II” or the “WEST II Notes”) is a bankruptcy remote special purpose 
vehicle which was established for the purpose of financing aircraft engines through an asset-backed securitization (“ABS”). 
WEST II is a variable interest entity (“VIE”) which the Company owns 100% of the equity and consolidates in its financial 
statements. 

On August 4, 2017, the Company closed an asset-backed securitization through a newly-created, bankruptcy-remote, 
Delaware statutory trust, Willis Engine Structured Trust III (“WEST III” or the “WEST III Notes”), of which the Company 
is the sole beneficiary. The WEST III Notes were issued in two series, with the Series A Notes issued in an aggregate 
principal amount of $293.7 million and the Series B Notes in an aggregate principal amount of $42.0 million. The Company 
used these funds, net of transaction expenses, to pay off part of its revolving credit facility totaling $491.0 million. WEST 
III is a VIE which the Company owns 100% of the equity and consolidates in its financial statements.   

The assets and liabilities of WEST III remain on the Company’s balance sheet. A portfolio of commercial jet aircraft 
engines and leases thereon secures the obligations of WEST III under the ABS. The WEST III Notes have a scheduled 
amortization and are payable solely from revenue received by WEST III from the engines and the engine leases, after 
payment of certain expenses of WEST III. Series A Notes bear interest at a fixed rate of 4.69% per annum and Series B 
Notes bear interest at a fixed rate of 6.36% per annum. The WEST III Notes may be accelerated upon the occurrence of 
certain events, including the failure to pay interest for five business days after the due date thereof. The WEST III Notes 
are expected to be paid in 10 years. The legal final maturity of the Notes is August 15, 2042. 

In connection with the WEST III transactions, the Company entered into a Servicing Agreement and Administrative 
Agency Agreement with WEST III to provide certain engine, lease management and reporting functions for WEST III in 
return for fees based on a percentage of collected lease revenues and asset sales.  Because WEST III is consolidated for 
financial statement reporting purposes, all fees eliminate upon consolidation.  

On August 22, 2018, Willis Engine Structured Trust IV (“WEST IV”), a consolidated VIE of the Company closed its 
offering of $373.4 million in aggregate principal amount of fixed rate notes (the “WEST IV Notes”). The WEST IV Notes 
were issued in two series, with the Series A Notes issued in an aggregate principal amount of $326.8 million and the Series 
B Notes in an aggregate principal amount of $46.7 million. The WEST IV Notes are secured by, among other things, 
WEST IV’s direct and indirect interests in a portfolio of assets.  

56 

   
   
The Series A Notes have a fixed coupon of 4.75%, an expected maturity of approximately eight years and a final 
maturity  date  of  September  15,  2043.  The  Series  B  Notes  have  a  fixed  coupon  of  5.44%,  an  expected  maturity  of 
approximately eight years and a final maturity date of September 15, 2043. The Series A Notes were issued at a price of 
99.99504% of par and the Series B Notes were issued at a price of 99.99853% of par. Principal and interest on the WEST 
IV Notes are payable monthly to the extent of available cash in accordance with a priority of payments included in the 
Indenture. Proceeds from asset sales by WEST IV will be used, at WEST IV’s election subject to certain conditions, to 
reduce WEST IV’s debt or to acquire other engines or airframes.  

The assets of WEST II, WEST III and WEST IV are not available to satisfy the Company’s obligations other than the 
obligations specific to the respective ABS. WEST II, WEST III and WEST IV are consolidated for financial statement 
presentation purposes. The ABSs’ ability to make distributions and pay dividends to the Company is subject to the prior 
payments of its debt and other obligations and maintenance of adequate reserves and capital. Under each ABS, cash is 
collected  in  a  restricted  account,  which  is  used  to  service  the  debt  and  any  remaining  amounts,  after  debt  service  and 
defined expenses, are distributed to the Company. Additionally, a portion of the maintenance reserve payments and lease 
security deposits are formulaically accumulated in restricted accounts and are available to fund future maintenance events 
and to secure lease payments, respectively. 

(b)   Basis of Presentation and Principles of Consolidation 

The accompanying consolidated financial statements include the accounts of Willis Lease Finance Corporation and 
its  wholly  owned  subsidiaries,  including  VIEs  where  the  Company  is  the  primary  beneficiary  in  accordance  with 
consolidation  guidance.  The  Company  evaluates  all  entities  in  which  it  has  an  economic  interest  firstly  to  determine 
whether for accounting purposes the entity is a variable interest entity or voting interest entity. If the entity is a variable
interest entity the Company consolidates the financial statements of that entity if it is the primary beneficiary of the entities’
activities.  If the entity is a voting interest entity the Company consolidates the entity when it has a majority of voting 
interests. Intercompany transactions and balances have been eliminated in consolidation.  

The condensed parent company financial statements should be read in conjunction with the Company’s consolidated 

financial statements and the accompanying notes herein.  

(c)   Revenue Recognition 

Leasing revenue  

Revenue from leasing of engines, aircraft and related parts and equipment is recognized as operating lease revenue on 
a straight-line basis over the terms of the applicable lease agreements. Revenue is not recognized when cash collection is 
not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status and 
revenue is recognized when cash payments are received.  

Under the terms of some of the Company’s leases, the lessees pay use fees (also known as maintenance reserves) to 
the Company based on usage of the leased asset, which are designed to cover expected future maintenance costs. Some of 
these amounts are reimbursable to the lessee if they make specifically defined maintenance expenditures. Use fees received 
are recognized in revenue as maintenance reserve revenue if they are not reimbursable to the lessee. Use fees that are 
reimbursable are recorded as a maintenance reserve liability until they are reimbursed to the lessee,  the lease terminates, 
or the obligation to reimburse the lessee for such reserves ceases to exist, at which time they are recognized in revenue as 
maintenance reserve revenue.  

Certain lessees may be significantly delinquent in their rental payments and may default on their lease obligations. As 
of December 31, 2018, the Company had an aggregate of approximately $4.8 million in lease rent and $5.6 million in 
maintenance reserve receivables more than 30 days past due. Inability to collect receivables or to repossess engines or 
other leased equipment in the event of a default by a lessee could have a material adverse effect on the Company. The 
Company estimates an allowance for doubtful accounts for receivables it does not consider fully collectible. The allowance 
for  doubtful  accounts  includes  the  following:  (1) specific  reserves  for  receivables  which  are  impaired  for  which 

57 

   
   
   
   
   
management  believes  full  collection  is  doubtful;  and  (2) a  general  reserve  for  estimated  losses  based  on  historical 
experience.   

No customer accounted for greater than 10% of total lease rent revenue in 2018, 2017 and 2016. 

Gain on sale of leased equipment    

The Company regularly sells equipment from its lease portfolio. This equipment may or may not be subject to a lease 
at the time of sale. The net gain or loss on such sales is recognized as revenue and consists of proceeds associated with the 
sale less the net book value of the asset  sold and any direct costs associated with the sale. To the extent that deposits 
associated with the equipment are not included in the sale, any such amount is included in the calculation of gain or loss.  

Spare parts sales  

The Spare Parts Sales reportable segment primarily engages in the sale of aircraft engine parts and materials through 
the acquisition or consignment of engines from third parties or the Company’s leasing operations. The parts are sold at a 
fixed price with no right of return. In determining the performance obligation, management has identified the promise in 
the contract to be the shipment of the spare parts to the customer.  Title passes to the buyer when the goods are shipped, 
and the buyer is responsible for any loss in transit, and the Company has a legal right to  payment for the spare parts. 
Management has determined that physical acceptance of the spare parts to be a formality in accordance with Accounting 
Standards Codification (“ASC”) 606-10-5-86.   

The spare parts transaction price is a fixed dollar amount and is stated on each purchase order for a fixed amount by 
total number of parts. Spare parts revenue is based on a set price for a set number of parts as defined in the purchase order. 
The performance obligation is completed once the parts have shipped and, as a result, all of the transaction price is allocated
to that performance obligation. Management has determined that it is appropriate for the Company to recognize spare parts 
sales at a point in time (i.e., the date the parts are shipped) under ASC 606. Additionally, there is no impact to the timing 
and amounts of revenue recognized for spare parts sales related to the implementation of ASC 606.  

Equipment Sales  

Equipment  sales  represent  the  selective  purchase  and  resale  of  commercial  aircraft  engines  and  other  aircraft 
equipment. The Company and customer enter into an agreement which outlines the place and date of sale, purchase price, 
payment terms, condition of the asset, bill of sale, and the assignment of rights and warranties from the Company to the 
customer. Management has identified the promise in the equipment sale contract to be the transfer of ownership of the 
asset. Management believes the asset holds standalone value to the customer as it is not dependent on any other services 
for functionality purposes and therefore is distinct within the context of the contract and as described in ASC 606-10. As 
such, management has identified the transfer of the asset as the performance obligation. The transaction price is set at a 
fixed dollar amount per fixed quantity (number of assets) and is explicitly stated in each contract. Equipment sales revenue 
is based on a set price for a set number of assets, which is allocated to the performance obligation discussed above, in its 
entirety. The Company has determined the date of transfer to the customer to be the date the customer obtains control and 
title over the asset and the date which revenue is to be recognized and payment is due. As such, there is no impact to the 
timing and amounts of revenue recognized for equipment sales related to the implementation of ASC 606.  

Managed Services  

Managed  services  revenue predominantly  represents  fleet management  and  engine  storage  services which  may  be 
combined on a single contract with a customer. Fleet management services are performed for a stated fixed fee as agreed 
upon in the services agreement. Engine storage services are for a fixed monthly fee. For a contract containing more than 
one performance obligation, the allocation of the transaction price is generally performed on the basis of the relative stand-
alone selling price of each distinct good or service in the contract. As each of the services provided within the contract 
have separate prices, the Company allocates the price to its related performance obligation described above. Management 
has determined each of the revenue elements contain performance obligations that are satisfied over time and therefore 
recognizes revenue over time in accordance with ASC 606-10-25-27. The Company utilizes the percentage-of-completion 

58 

   
   
   
   
   
   
   
   
method  (input  method)  for  recognizing  fleet  management  services  and  will  calculate  revenues  based  on  labor  hours 
incurred. Additionally, as is required by ASC 606-10-25-35, as circumstances change over time, the Company will update 
its measure of progress to reflect any changes in the outcome of the performance obligation. Engine storage services are 
recognized on a monthly basis utilizing the input method of days passed. Therefore, there is no impact to the timing and 
amounts of revenue recognized for managed services related to the implementation of ASC 606.  

Amounts owed for managed services are typically billed upon contract completion. At January 1, 2018, $0.4 million 
of unbilled revenue associated with outstanding contracts was reported in Other assets, all of which was recognized by 
December 31, 2018. At December 31, 2018, unbilled revenue was $0.6 million and the Company expects it to be fully 
recognized  by  June  30,  2019.  Additionally,  manages  services  are  presented  within  the  Other  revenue  line  in  the 
Consolidated Statements of Income. 

Other Revenue 

Other  revenue  consists  primarily  of  management  fee  income,  lease  administration  fees,  third  party  consignment 
commissions earned, service fee revenue, and other discrete revenue items. During the year ended December 31, 2017, 
other revenue included a net gain on an insurance settlement of $1.3 million related to a leased aircraft.  

(d)   Equipment Held for Operating Lease 

Aircraft  assets  held  for  operating  lease  are  stated  at  cost,  less  accumulated  depreciation.  Certain  costs  incurred  in 
connection with the acquisition of aircraft assets are capitalized as part of the cost of such assets. Major overhauls paid for
by the Company, which improve functionality or extend the original useful life, are capitalized and depreciated over the 
shorter of the estimated period to the next overhaul (“deferral method”) or the remaining useful life of the equipment. The 
Company does not accrue for planned major maintenance. The cost of overhauls of aircraft assets under long term leases, 
for  which  the  lessee  is  responsible  for  maintenance  during  the  period  of  the  lease,  are  paid  for  by  the  lessee  or  from 
reimbursable maintenance reserves paid to the Company in accordance with the lease, and are not capitalized. 

Based on specific aspects of the equipment, the Company generally depreciates engines on a straight-line basis over 
a 15-year period from the acquisition date to a 55% residual value. This methodology is believed to accurately reflect the 
Company’s typical holding period for the engine assets and, that the residual value assumption reasonably approximates 
the selling price of the assets 15 years from date of acquisition. The typical 15 year holding period is the estimated useful 
life of the Company’s engines based on its business model and plans, and represents how long the Company anticipates 
holding a newly acquired engine. The technical useful life of a new engine can be in excess of 25 years. The Company 
reviews the useful life and residual values of all engines periodically as demand changes to accurately depreciate the cost 
of equipment over the useful life of the engines. 

The aircraft and airframes owned by the Company are depreciated on a straight-line basis over an estimated useful 
life of 13 to 20 years to a 15% to 17% residual value. The other leased parts and related equipment owned by the Company 
are depreciated on a straight-line basis over an estimated useful life of 14 to 15 years to a 25% residual value. 

The useful life of older generation engines and aircraft may be significantly less based upon the technical status of the 
engine, as well as supply and demand factors. For these older generation engines and aircraft, the remaining useful life and 
the remaining expected holding period are typically the same. For older generation engines or aircraft that are unlikely to 
be  repaired  at  the  end  of  the  current  expected  useful  lives,  the  Company  depreciates  the  engines  or  aircraft  over  their 
estimated  lives  to  a  residual  value  based  on  an  estimate  of  the  wholesale  value  of  the  parts  after  disassembly.  As  of 
December 31, 2018, 34 engines having a net book value of $46.3 million were depreciated under this policy with estimated 
useful lives ranging from 1 to 80 months. The Company adjusts its estimates annually for these older generation assets, 
including updating estimates of an engine’s or aircraft’s remaining operating life as well as future residual value expected 
from part-out based on the current technical status of the engine or aircraft. 

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that 
the carrying amount of an asset may not be recoverable. Long-lived assets to be disposed are reported at the lower of 
carrying  amount  or  fair  value  less  cost  to  sell.  Impairment  is  identified  by  review  of  appraisals  or  by  comparison  of 

59 

   
undiscounted forecasted cash flows, including estimated sales proceeds, over the life of the asset with the assets’ book 
value. If the forecasted undiscounted cash flows are less than the book value, the asset is written down to its fair value. 
Fair value is determined per individual asset by reference to independent appraisals, quoted market prices (e.g. an offer to 
purchase) and other factors considered relevant by the Company. The Company conducts a formal annual review of the 
carrying value of long-lived assets and also evaluates assets during the year if a triggering event is identified indicating 
impairment is possible. Such annual review resulted in an impairment charge of $5.3 million, $4.4 million and $1.8 million 
in 2018, 2017, and 2016, respectively (included in “Write-down of equipment” in the Consolidated Statements of Income).   

(e)   Equipment Held for Sale 

Equipment held for sale includes engines being marketed for sale as well as third party consigned assets. The assets 

to be disposed are reported at the lower of carrying amount or fair value less costs to sell. 

(f)   Debt Issuance Costs and Related Fees 

Fees paid in order to secure debt are capitalized, included in Debt obligations on the Consolidated Balance Sheets, 

and amortized over the life of the related loan using the effective interest method.  

(g)   Interest Rate Hedging 

The  Company  enters  into  various  derivative  instruments  periodically  to  mitigate  the  exposure  on  variable  rate 
borrowings. The derivative instruments are fixed-rate interest swaps that are recorded at fair value as either an asset or 
liability.  

While substantially all of the Company’s derivative transactions are entered into for the purposes described above, 
hedge accounting is only applied where specific criteria have been met and it is practicable to do so. In order to apply 
hedge accounting, the transaction must be designated as a hedge and it must be highly effective. The hedging instrument’s 
effectiveness  is  assessed  utilizing  regression  analysis  at  the  inception  of  the  hedge  and  on  at  least  a  quarterly  basis 
throughout its life. All of the transactions that the Company has designated as hedges are cash flow hedges. The effective 
portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported as a component 
of other comprehensive income and is reclassified into earnings in the period during which the transaction being hedged 
affects earnings. The ineffective portion of the hedges is recorded in earnings in the current period. 

(h)   Income Taxes 

The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, 
deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory 
tax rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of 
existing assets and liabilities. The effect on deferred taxes of a change in the tax rates is recognized in income in the period
that includes the enactment date. 

The Company recognizes in the financial statements the impact of a tax position, if that position is more likely than 
not of being sustained on audit, based on the technical merits of the position. Recognized income tax positions are measured 
at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected 
in the period in which the change in judgment occurs (see Note 7). 

The Company files income tax returns in various states and countries which may have different statutes of limitations. 
The  Company  records  penalties  and  accrued  interest  related  to  uncertain  tax  positions  in  income  tax  expense.  Such 
adjustments have historically been minimal and immaterial to our financial results. 

60 

(i)   Property, Equipment and Furnishings 

Property,  equipment  and  furnishings  are  recorded  at  cost  and  depreciated  using  the  straight-line  method  over  the 
estimated  useful  lives  of  the  related  assets,  which  range  from  three  to  thirty-nine  years.  Leasehold  improvements  are 
recorded at cost and depreciated by the straight-line method over the shorter of the lease term or useful life of the leasehold.

(j)   Cash and Cash Equivalents 

The  Company  considers  highly  liquid  investments  readily  convertible  into  known  amounts  of  cash,  with  original 

maturities of 90 days or less, as cash equivalents. 

(k)   Restricted Cash  

The Company has certain bank accounts that are subject to restrictions in connection with its WEST II, WEST III and 
WEST IV borrowings. Under these borrowings, cash is collected in restricted accounts, which are used to service the debt 
and  any  remaining  amounts,  after  debt  service  and  defined  expenses,  are  distributed  to  the  Company.  Additionally,  a 
portion  of  maintenance  reserve  payments  and  some  or  all  of  the  lease  security  deposits  are  accumulated  in  restricted 
accounts and are available to fund future maintenance events and to secure lease payments, respectively. Under WEST II, 
cash from maintenance reserve payments is held in a restricted cash account equal to the maintenance obligations projected 
for the subsequent six months, and is subject to a minimum balance of $9.0 million. Under WEST III and WEST IV, cash 
from maintenance reserve payments is held in a restricted cash account equal to a portion of the maintenance obligations 
projected  for  the  subsequent nine  months,  and  is  subject  to  a  minimum  balance  of $10.0  million. Under WEST  II, all 
security deposits are held in a restricted cash account until the end of the lease. Under WEST III and WEST IV, security 
deposits are held in a restricted cash account equal to a portion of the security deposits for leases scheduled to terminate 
over the subsequent four months, subject to a minimum balance of $1.0 million. Provided lease return conditions have 
been met, these deposits will be returned to the lessee. To the extent return conditions are not met, these deposits may be 
retained by the Company. 

(l)   Spare Parts Inventory 

Spare parts inventory consists of spare aircraft and engine parts purchased either directly by Willis Aero and also 
engines removed from the lease portfolio to be parted out. Spare parts inventory is stated at lower of cost or net realizable 
value. An impairment charge for excess or inactive inventory is recorded based upon an analysis that considers current 
inventory levels, historical usage patterns, future sales expectations and salvage value. 

(m)   Intangible Assets 

Intangible  assets  include  customer  relationships  and  goodwill  arising  from  the  Company’s  acquisitions  of  TES.  

Intangible assets are accounted for in accordance with ASC 350, “Intangibles — Goodwill and Other.” 

Customer  relationships  are  amortized  on  a  straight  line  basis  over  their  estimated  useful  life  of  five  years.  The 

Company has no intangible assets with indefinite useful lives. Goodwill is assessed for impairment annually. 

(n)   Other assets 

Other assets typically include prepaid purchase deposits and other prepaid expenses. As of December 31, 2018 and 
2017, other assets included prepaid deposits of $1.9 million and $36.5 million, respectively, relating to commitments to 
purchase equipment. 

(o)   Management Estimates 

These  financial  statements  have  been  prepared  on  the  accrual  basis  of  accounting  in  accordance  with  accounting 

principles generally accepted in the United States. 

61 

The preparation of consolidated financial statements requires management to make estimates and judgments that affect 
the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.
Management evaluates estimates on an ongoing basis, including those related to residual values, estimated asset lives, 
impairments and bad debts. Estimates are based on historical experience and on various other assumptions that are believed 
to be reasonable under the circumstances for making judgments about the carrying values of assets and liabilities that are 
not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or 
conditions. 

Management believes that the accounting policies on revenue recognition, maintenance reserves and expenditures, 
useful life of equipment, asset residual values, asset impairment and allowance for doubtful accounts are critical to the 
results of operations. 

If the useful lives or residual values are lower than those estimated, upon sale of the asset a loss may be realized. 
Significant  management  judgment  is  required  in  the  forecasting  of  future  operating  results,  which  are  used  in  the 
preparation  of  projected  undiscounted  cash-flows  and  should  different  conditions  prevail,  material  impairment  write-
downs may occur. 

(p)   Earnings per share information 

Basic earnings per common share is computed by dividing net income by the weighted average number of common 
shares outstanding for the period. Diluted earnings per common share is computed by dividing net income by the weighted 
average number of shares outstanding, adjusted for the dilutive effect of unvested restricted stock awards (“RSA’s”). See 
Note 9 for more information on the computation of earnings per share. 

(q)   Investments 

The Company’s investments are joint ventures, where it owns 50% of the equity of the ventures and are accounted for 
using the equity method of accounting. The investments are recorded at the amount invested plus or minus our 50% share 
of net income or loss, less any distributions or return of capital received from the entities. 

(r)   Stock Based Compensation 

The Company recognizes stock based compensation expense in the financial statements for share-based awards based 
on the grant-date fair value of those awards. Stock based compensation expense is recognized over the requisite service 
periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Additionally, the 
Company implemented ASU 2016-09 in the first quarter of 2017, using the modified retrospective approach, and elected 
to account for forfeitures as they occur. As such, a $1.3 million cumulative effect adjustment was recorded to the opening 
balance of Retained earnings for the impact in tax benefits as well as the differential between the amount of compensation 
cost previously recorded and the amount that would have been recorded without assuming forfeitures.  

(s)   Initial Direct Costs associated with Leases 

The Company accounts for the initial direct costs, including sales commissions and legal fees, incurred in obtaining a 
new lease by deferring and amortizing those costs over the term of the lease. The amortization of these costs is recorded 
under  General  and  administrative  expenses  in  the  Consolidated  Statements  of  Income. The  amounts  amortized  were 
$1.9 million, $1.8 million and $1.6 million for the years ended December 31, 2018, 2017 and 2016, respectively. 

62 

(t)   Maintenance Rights 

The  Company  identifies,  measures  and  accounts  for  maintenance  right  assets  and  liabilities  associated  with 
acquisitions of equipment with in-place leases. A maintenance right asset represents the fair value of the contractual right 
under a lease to receive equipment in an improved maintenance condition as compared to the maintenance condition on 
the acquisition date. A maintenance right liability represents the Company's obligation to pay the lessee for the difference 
between the lease-end contractual maintenance condition of the equipment and the actual maintenance condition of the 
equipment on the acquisition date.  The equipment condition at the end of the lease term may result in either overhaul work 
being performed by the lessee to meet the required return condition or a financial settlement. 

When a capital event is performed on the equipment by the lessee, which satisfies their maintenance right obligation, 
the maintenance rights are added to the equipment basis and depreciated to the next capital event. When equipment is sold 
before the end of the pre-existing lease, the maintenance rights are applied against any accumulated maintenance reserves, 
if paid by the lessee, and the remaining balance is applied to the disposition gain or loss. When a lease terminates, an end 
of lease true-up is performed and the maintenance right is applied against the accumulated maintenance reserves or, for 
non-reserve  lessees  the  final  settlement  payment,  and  any  remaining  net  maintenance  right  is  recorded  in  the  income 
statement. 

(u)   Foreign Currency Translation 

The Company’s foreign investments have been converted at rates of exchange in effect at the balance sheet dates. The 
changes in exchange rates in our foreign investments reported under the equity method are included in stockholders’ equity 
as accumulated other comprehensive income. 

(v)   Risk Concentrations 

Financial instruments which potentially subject us to concentrations of credit risk consist principally of cash deposits, 

lease receivables and interest rate swaps. 

The Company places our cash deposits with financial institutions and other creditworthy institutions such as money 
market funds and limits the amount of credit exposure to any one party. Management opts for security of principal as 
opposed to yield. Concentrations of credit risk with respect to lease receivables are limited due to the large number of 
customers comprising the customer base, and their dispersion across different geographic areas. Some lessees are required 
to make payments for maintenance reserves at the end of the lease however, this risk is considered limited due to the 
relatively few lessees which have this provision in the lease. The Company enters into interest rate swap agreements with 
counterparties that are investment grade financial institutions. 

(w)   Recent Accounting Pronouncements 

Recent Accounting Pronouncements Adopted by the Company 

In  May  2014,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Accounting  Standard  Update  (“ASU”) 
2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). ASU 2014-09 amends the accounting guidance 
on  revenue  recognition.  The  amendments  in  this  accounting  standard  update  are  intended  to  provide  a  more  robust 
framework for addressing revenue issues, improve comparability of revenue recognition practices, and improve disclosure 
requirements.  Under  the  new  standard,  revenue  is  recognized  when  a  customer  obtains  control  of  promised  goods  or 
services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for 
those goods or services. The principles in the standard should be applied using a five-step model that includes 1) identifying 
the contract(s) with a customer, 2) identifying the performance obligations in the contract, 3) determining the transaction 
price, 4) allocating the transaction price to the performance obligations in the contract, and 5) recognizing revenue when 
(or as) the performance obligations are satisfied. The standard also requires disclosure of the nature, amount, timing, and 
uncertainty of revenue and cash flows arising from contracts with customers. In addition, the standard amends the existing 
requirements for the recognition of a gain or loss on the transfer of nonfinancial assets that are and are not in a contract 
with  a  customer  (for  example,  sales  of  real  estate)  to  be  consistent  with  the  standard’s  guidance  on  recognition  and 

63 

measurement  (including  the  constraint  on  revenue).  The  FASB  also  subsequently  issued  several  amendments  to  the 
standard, including clarification on principal versus agent guidance, identifying performance obligations, and immaterial 
goods and services in a contract.  

The  Company  adopted  ASU  2014-09  and  its  related  amendments  (collectively  known  as  ASC  606)  effective  on 
January  1,  2018  using  the  modified  retrospective  approach  applied  only  to  contracts  not  completed  as  of  the  date  of 
adoption, with no restatement of comparative periods. Therefore, the comparative information has not been adjusted and 
continues to be reported under ASC Topic 605. Please see Note 1(c) for a discussion of the Company’s updated policies 
related to revenue recognition and accounting for costs to obtain and fulfill a customer contract and Note 2 "Revenue from 
Contracts with Customers" for the disclosures related to the impact of adopting this standard. 

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230), Classification of Certain 
Cash Receipts and Cash Payments” (a consensus of the Emerging Issues Task Force) to improve the diversity in practice 
in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update 
provides  guidance  on  specific  cash  flow  classification  issues  including  the  following:  (1)  debt  prepayment  or  debt 
extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates 
that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made 
after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of 
corporate-owned  life  insurance  policies,  including  bank-owned  life  insurance  policies;  (6)  distributions  received  from 
equity method investees; (7) beneficial interests in securitization transactions; and (8) separately identifiable cash flows 
and application of the predominance principle. Prior GAAP did not include specific guidance on these eight cash flow 
classification issues. The Company adopted the guidance effective January 1, 2018 and utilizing the cumulative earnings 
approach on a retrospective basis, reclassified $1.9 million and $1.2 million of distributions from joint ventures during 
2017  and  2016,  respectively,  from  cash  flows  from  investing  activities  to  cash  flows  from  operating  activities.  The 
remaining provisions of this update did not have a material impact on the Company’s consolidated statements of cash 
flows. 

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the 
Test  for  Goodwill  Impairment,”  (“ASU  2017-04”)  that  eliminates  “Step  2”  from  the  goodwill  impairment  test.  The 
Company  made  the  election  to  early  adopt  ASU  2017-04  as  of  January  1,  2018  and  the  standard  was  applied  on  a 
prospective  basis,  as  required.    The  adoption  of  this  standard  did  not  have  an  impact  on  the  consolidated  financial 
statements or the related disclosures. 

In February 2017, the FASB issued ASU 2017-05, “Other Income – Gains and Losses from the Derecognition of 
Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial 
Sales of Nonfinancial Assets”. The FASB issued this ASU to clarify the scope of subtopic 610-20, which was issued in 
May 2014 as part of ASU 2014-09. The effective date and transition requirements of these amendments are the same as 
the effective date and transition requirements of ASU 2014-09. On January 1, 2018 the Company adopted this standard 
utilizing  the  modified  retrospective  approach  and  the  practical  expedient  under  ASC  606-10-65-1  which  allowed  the 
Company  the  election  to  not  apply  the  guidance  to  completed  contracts.  As  there  were  no  incomplete  contracts  as  of 
January 1, 2018, the Company did not have a cumulative effect adjustment to retained earnings upon adoption. 

In  May  2017,  the  FASB  issued  ASU  2017-09,  “Compensation—Stock  Compensation  (Topic  718):  Scope  of 
Modification  Accounting,”  that  provides  guidance  about  which  changes  to  the  terms  or  conditions  of  a  share-based 
payment award require an entity to apply modification accounting. The new guidance became effective for the Company 
on January 1, 2018 and was applied on a prospective basis, as required. The adoption of this standard did not have an 
impact on the consolidated financial statements or the related disclosures. 

In February 2018, the FASB issued ASU 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 
220):  Reclassification  of  Certain  Tax  Effects  from  Accumulated  Other  Comprehensive  Income”  (“ASU  2018-02”)  to 
address stakeholder concerns about the guidance in current GAAP that requires deferred tax liabilities and assets to be 
adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the 
reporting period that includes the enactment date. The amendments in this update allow a reclassification from accumulated 
other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 

64 

(the “2017 Act”). The ASU must be applied either in the period of adoption or retrospectively to each period in which the 
effect of the change in the U.S. federal corporate income tax rate in the 2017 Act is recognized. The Company made the 
election to early adopt ASU 2018-02 as of January 1, 2018 (the period of adoption) and recorded a reclassification of $59 
thousand between Other comprehensive income and Retained earnings as of January 1, 2018.  

In  September  2018,  the  FASB  issued  ASU  2018-15,  “Intangibles  –  Goodwill  and  Other  –  Internal-Use  Software 
(Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That 
Is a Service Contract” (“ASU 2018-15”) which requires cloud computing arrangements in a service contact to follow the 
internal-use software guidance provided by ASC 350-40 in determining the accounting treatment of implementation costs. 
ASC 350-40 states that only qualifying costs incurred during the application development stage may be capitalized. The 
Company made the election to early adopt ASU 2018-15 on a retrospective basis, and during 2018 has capitalized $0.9 
million in cloud computing arrangement implementation costs which is presented within Other assets. There was no prior 
period impact related to the adoption of ASU 2018-15. 

Recent Accounting Pronouncements To Be Adopted by the Company 

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to 
Accounting  for  Hedging  Activities”  (“ASU  2017-12”).  The  ASU  is  targeted  at  simplifying  the  application  of  hedge 
accounting and aims at aligning the recognition and presentation of the effects of hedge instruments and hedge items. ASU 
2017-12 is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The 
Company plans to adopt this guidance effective January 1, 2019 and is currently evaluating the potential impact adoption 
will have on the consolidated financial statements and related disclosures. 

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326) Measurement of 
Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 revises the measurement of credit losses for 
financial assets measured at amortized cost from an incurred loss methodology to an expected loss methodology. ASU 
2016-13 affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a 
right to receive cash. Additional disclosures about significant estimates and credit quality are also required. In November 
2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses”. 
This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial 
instruments. The effective date will be the first quarter of fiscal year 2021, with early adoption permitted beginning in 
fiscal year 2020. The Company is evaluating the potential effects on the consolidated financial statements. 

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASC 842”) that amends the accounting 
guidance on leases for both lessees and lessors. The new standard establishes a right-of-use (“ROU”) model that requires 
a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. 
Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in 
the income statement. The FASB also subsequently issued amendments to the standard, including providing an additional 
and optional transition method to adopt the new standard, described below, as well as certain practical expedients related 
to land easements and lessor accounting. The amendments in this accounting standard update are effective for the Company 
on January 1, 2019, with early adoption permitted. The Company will adopt this accounting standard update effective 
January 1, 2019. 

The  accounting  standard  update  originally  required  the  use  of  a  modified  retrospective  approach  reflecting  the 
application of the  standard  to  leases  existing  at, or  entered  into  after,  the  beginning of  the  earliest  comparative  period 
presented in the financial statements with the option to elect certain practical expedients. A subsequent amendment to the 
standard provides an additional and optional transition method that allows entities to initially apply the new leases standard 
at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period 
of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which 
it adopts the new leases standard will continue to be in accordance with ASC Topic 840 if the optional transition method 
is  elected.  The  Company  plans  to  adopt  the  standard  using  the  optional  transition  method  with  no  restatement  of 
comparative periods and a cumulative effect adjustment, if any, recognized as of the date of adoption.  

65 

   
The  Company  does  not  expect  that  this  standard  to  have  a  material  effect  on  its  financial  statements  due  to  the 
recognition of new ROU assets and lease liabilities for lessee activities. Additionally, while the Company continues to 
evaluate certain aspects of the new standard in its lessor capacity, including those still being revised by the FASB, the 
Company does not expect the new standard will have a material effect on its financial statements and also does not expect 
a significant change in its leasing activities between now and adoption. 

As part of the implementation process, the Company assessed its lease arrangements and evaluated practical expedient 
and accounting policy elections to meet the reporting requirements of this standard. The Company has also evaluated the 
changes in controls and processes that are necessary to implement the new standard, and no material changes were required. 
The  new  standard  provides  a  number  of  optional  practical  expedients  in  transition.  The  Company  expects  to  elect  the 
‘package of practical expedients’ which permits us not to reassess under the new standard the prior conclusions about lease 
identification, lease classification, and initial direct costs. The Company does not expect to elect the use-of-hindsight or 
the practical expedient pertaining to land easements; the latter not being applicable to WLFC. Consequently, on adoption, 
the  Company  expects  to  recognize  additional  operating  liabilities  ranging  from  $4.0  million  to  $5.0  million,  with 
corresponding ROU assets of approximately the same amount based on the present value of the remaining minimum rental 
payments under current leasing standards for existing operating leases.  

Under ASC 842, a lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, 
in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional 
criteria are both met, indicating that the lessor has transferred substantially all the risks and benefits of the underlying asset
to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing 
leases are operating leases. As lessor, the Company believes substantially all of its leases will continue to be classified as 
operating leases under the new standard. In addition, due to the new standard’s narrowed definition of initial direct costs, 
the Company expects to expense as incurred certain lease origination costs currently capitalized as initial direct costs and 
amortized to expense over the lease term.  

The  new  standard  also  provides  practical  expedients  for  an  entity’s  ongoing  accounting.  The  Company  currently 
expects to elect the short-term lease recognition exemption for  all leases that qualify. As a result, for those leases that 
qualify, the Company will not recognize ROU assets or lease liabilities, including for existing short-term leases of those 
assets in transition. The Company also currently expects to elect the practical expedient to not separate lease and non-lease 
components for the majority of its leases as both lessee and lessor. The Company also expects significant new disclosures 
about its leasing activities in accordance with the new standard. 

2. Revenue from Contracts with Customers

As of January 1, 2018, the Company adopted ASU 2014-09 and all subsequent ASUs that modified ASC 606. While 
only a portion of the Company’s revenues is impacted by this guidance as it does not apply to contracts falling under the 
leasing standard, as part of the implementation process the Company performed an analysis to identify accounting policies 
that needed to change and additional disclosures that are  required. The Company considered factors such as customer 
contracts with unique revenue recognition considerations, the nature and type of goods and services offered, the degree to 
which contracts include multiple performance obligations or variable consideration, and the pattern in which revenue is 
currently recognized, among other things. All revenue streams applicable to the new standard (Spare parts and equipment 
sales  and  Managed  services  which  is  reflected  within  Other  revenue)  were  evaluated  by  management.  The  Company 
considered recognition under the new standard and concluded the timing of the Company’s revenue recognition will remain 
the same. Additionally, the Company determined the transfer of engines and airframes from the lease portfolio to the  Spare 
Parts  segment  for  part  out  represent  sales  to  customers  in  accordance  with  the  ordinary  operations  of  our  Spare  Parts 
reportable  segment.  As  such,  the  Company  presents  the  sale  of  these  assets  on  a gross  basis  and have  reclassified  the 
revenue on sale to the Spare parts and equipment sales line item from the net gain (loss) presentation within the Gain on 
sale of leased equipment line item.

In addition the change in presentation of certain spare parts sales noted above has caused proceeds from sale of such 
parts  to  be  recorded  in  cash  flows  from  operating  activities  having  previously  been  recorded  as  sale  proceeds  within 
investing activities.  This caused an increase in cash flows from operating activities of $16.9 million in the year ended 
December 31, 2018 and an equal decrease in proceeds from sale of equipment within investing activities.

(2) Leasing revenue is recognized under the lease accounting guidance in ASC 840 Leases, and therefore qualifies for the scope exception under ASC 

606. Total Leasing revenue includes $3.3 million that is presented in Other revenue line item on the Consolidated Statement of Income.

3. Equipment Held for Operating Lease

As of December 31, 2018, the Company had a total lease portfolio of 244 engines and related equipment, 17 aircraft 
and 10 other leased parts and equipment with a net book value of $1,673.1 million. As of December 31, 2017, the Company 
had a total lease portfolio of 225 aircraft engines and related equipment, 16 aircraft and 7 other leased parts and equipment, 
with a net book value of $1,342.6 million. 

A majority of the equipment is leased and operated internationally. Substantially all leases relating to this equipment 

are denominated and payable in U.S. dollars.

In 2011, the Company entered into an agreement with Mitsui & Co., Ltd. to participate in a joint venture formed as a 
Dublin-based Irish limited company – Willis Mitsui & Company Engine Support Limited (“WMES”) for the purpose of 
acquiring and leasing jet engines. Each partner holds a fifty percent interest in the joint venture and the Company uses the 
equity method in recording investment activity. As of December 31, 2018, WMES owned a lease portfolio of 32 engines 
and one aircraft with a net book value of $234.8 million. 

In  2014,  the  Company  entered  into  an  agreement  with  China  Aviation  Supplies  Import  &  Export  Corporation 
(“CASC”) to participate in a joint venture named CASC Willis Engine Lease Company Limited (“CASC Willis”), a joint 
venture based in Shanghai, China. Each partner holds a fifty percent interest in the joint venture. CASC Willis acquires 
and  leases  jet  engines  to  Chinese  airlines  and  concentrates  on  the  demand  for  leased  commercial  aircraft  engines  and 
aviation assets in the People’s Republic of China. During 2016, CASC was reorganized, with portions of its partnership 
interest in CASC Willis being transferred to three Chinese airlines and another government-owned entity. The 2016 CASC 
reorganization resulted in no voting structure change to the joint venture. CASC Willis owned a lease portfolio of four 
engines with a net book value of $51.9 million as of December 31, 2018.

Virtually  all  of  the  above  debt  requires  ongoing  compliance  with  the  covenants  of  each  financing,  including 
debt/equity  ratios,  minimum  tangible  net  worth  and  minimum  interest  coverage  ratios,  and  other  eligibility  criteria 
including customer and geographic concentration restrictions. The Company also has certain negative financial covenants 
such as liens, advances, change in business, sales of assets, dividends and stock repurchases. These covenants are tested 
either monthly or quarterly and the Company was in full compliance with all financial covenant requirements at December 
31, 2018. 

At December 31, 2018, the Company had a revolving credit facility to finance the acquisition of equipment for lease 
as well as for general working capital purposes, with the amounts drawn under the facility not to exceed that which is 
allowed under the borrowing base as defined by the credit agreement. In April 2016, the Company entered into a Third 
Amended  and  Restated  Credit  Agreement  which  increased  the  revolving  credit  facility  to  $890.0  million  from  $700.0 
million and extended the term to April 2021.  This $890 million revolving credit facility has an accordion feature which 
would expand the entire credit facility up to $1 billion. As of December 31, 2018 and 2017, $463.0 million and $399.0 
million  were  available  under  this  facility,  respectively.  On  a  quarterly  basis,  the  interest  rate  is  adjusted  based  on  the 
Company’s leverage ratio, as calculated under the terms of the revolving credit facility. Under the revolving credit facility, 
all subsidiaries except WEST II, WEST III, and WEST IV jointly and severally guarantee payment and performance of 
the terms of the loan agreement. The guarantee would be triggered by a default under the agreement.  

At  December  31,  2018,  $369.2  million  of  WEST  IV  term  notes  were  outstanding. At  December  31,  2018  and 
2017,  $313.4 million and $330.7 million of WEST III term notes were outstanding, respectively. At December 31, 2018 
and 2017, $237.8 million and $259.0 million of WEST II term notes were outstanding, respectively. 

The assets of WEST II, WEST III and WEST IV are not available to satisfy the Company’s obligations other than the 
obligations  specific  to  that  WEST  entity.  WEST  II,  WEST  III  and  WEST  IV  are  consolidated  for  financial  statement 
presentation purposes. WEST II, WEST III and WEST IV’s ability to make distributions and pay dividends to the Company 
is subject to the prior payments of their debt and other obligations and their maintenance of adequate reserves and capital. 
Under WEST II, WEST III and WEST IV, cash is collected in a restricted account, which is used to service the debt and 
any remaining amounts, after debt service and defined expenses, are distributed to the Company. Additionally, a portion 
of maintenance reserve payments and lease security deposits are formulaically accumulated in restricted accounts and are 
available to fund future maintenance events and to secure lease payments, respectively. The WEST II, WEST III, and 
WEST IV indentures require that a minimum threshold of maintenance reserve and security deposit balances be held in 
restricted cash accounts.  

In September 2016, the Company entered into an amendment (the “Amendment No. 2”) to the Amended and Restated 
Trust Agreement of WEST II, as amended by Trust Amendment No. 1, dated September 2012. The Amendment No. 2 
allows the Company to make additional equity contributions to fund engine maintenance expenses, to make up shortfalls 
in required net sale proceeds from engine dispositions and to provide additional funds in the acquisition of replacement 
engines for WEST II. These potential future equity contributions by the Company are voluntary.  The Amendment No. 2 
also increases the percentage of WEST II engines subject to disposition and modifies certain concentration limits. 

In July 2014, the Company closed on a loan with a ten year term totaling $13.4 million. During 2016, the Company 
closed on two additional loans totaling $4.7 million, repayable over the same initial ten year term. The interest is payable 
at fixed rates ranging from 2.60% to 2.97%  for the initial five years of the loan term and principal and interest is paid 

71 

 
 
 
monthly. The loans provided 100% of the funding for the purchase of a corporate aircraft and subsequent modifications 
and upgrades. The balance outstanding on these loans was $10.9 million and $12.7 million as December 31, 2018 and 
December 31, 2017, respectively. 

In January 2018, the Company repaid an existing loan at the maturity date. The loan was secured by three engines. 

6. Derivative Instruments

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest rates, 
in particular one-month LIBOR, with $427.0 million and $501.3 million of borrowings at December 31, 2018 and 2017, 
respectively, at variable rates. As a matter of policy, management does not use derivatives for speculative purposes. During 
2016, the Company entered into one interest rate swap agreement which has notional outstanding amount of $100.0 million, 
with remaining terms of 28 months as of December 31, 2018. The fair value of the swap at December 31, 2018 and 2017 
was $1.7 million and $1.1 million, respectively, representing a net asset. The Company recorded a $(0.4) million, $0.6 
million and $25,000 adjustment to interest expense during the three years ended December 31, 2018, respectively from 
derivative investments. 

The Company estimates the fair value of  derivative instruments using a discounted cash flow technique and has used 
creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-
performance. Valuation of the derivative instruments requires certain assumptions for underlying variables and the use of 
different assumptions would result in a different valuation. Management believes it has applied assumptions consistently 
during the period. The Company applies hedge accounting and accounts for the change in fair value of its cash flow hedges 
through other comprehensive income for all derivative instruments. 

Effect of Derivative Instruments on Earnings in the Statements of Income and of Comprehensive Income 

The  following  tables  provide  additional  information  about  the  financial  statement  effects  related  to  the  cash  flow

The derivatives were designated in a cash flow hedging relationship with the effective portion of the change in fair 

value of the derivative reported in the cash flow hedges subaccount of accumulated other comprehensive income. 

The effective portion of the change in fair value on a derivative instrument designated as a cash flow hedge is reported 
as a component of other comprehensive income and is reclassified into earnings in the period during which the transaction 
being hedged affects earnings or it is probable that the forecasted transaction will not occur. The ineffective portion of the 
hedges  is  recorded  in  earnings  in  the  current  period.  However,  these  are  highly  effective  hedges  and  no  significant 
ineffectiveness occurred in the periods presented. 

Counterparty Credit Risk 

The  Company  evaluates  the  creditworthiness  of  the  counterparties  under  its  hedging  agreements.  The  swap 
counterparty for the interest rate swap entered into during 2016 was a large financial institution in the United States that 
possessed  an  investment  grade  credit  rating.  Based  on  this  rating,  the  Company  believes  that  the  counterparty  was 
creditworthy and that their continuing performance under the hedging agreement was probable, and did not require the 
counterparty to provide collateral or other security to the Company.

No  reserve  was  established  as  of  December  31,  2018  and  December  31,  2017  for  the  exposure  in  Europe.  If  the

As of December 31, 2018, the Company had net operating loss carry forwards of approximately $188.3 million for 
federal tax purposes and $0.8 million for state tax purposes. The federal net operating loss carry forwards will expire at 
various times from 2023 to 2037 and the state net operating loss carry forwards will expire at various times from 2019 to 
2038. Federal net operating loss generated in 2018 under US tax reform has an indefinite life. The gross 2004 California 
net operating loss of $5.5 million expired in 2018. There is a $0.7 million valuation allowance for net operating losses in 
California that expire between 2019 and 2038. The Company’s ability to utilize the net operating loss and tax credit carry 
forwards in the future may be subject to restriction in the event of past or future ownership changes as defined in Section 

74 

     
 
  
 
  
 
 
 
 
 
 
 
 
    
     
 
 
 
  
  
  
  
  
382 of the Internal Revenue Code and similar state tax law. In 2017, the Company included the alternative minimum tax 
credit of approximately $0.4 million for federal income tax purposes as a tax receivable and will recognize this credit 
between 2-4 years to offset future regular tax liabilities. Management believes that no valuation allowance is required on 
deferred tax assets related to federal net operating loss carry forwards, as it is more likely than not that all amounts are 
recoverable through future taxable income. The open tax years for federal and state tax purposes are from 2015-2018 and 
2014-2018, respectively. 

On December 22, 2017, the 2017 Act was signed into law, making significant changes to the Internal Revenue Code. 
Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning 
after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, 
and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 
2017. The Company calculated the impact of the 2017 Act in the 2017 year end income tax provision in accordance with 
management’s  understanding  of  the  2017  Act  and  guidance  available  as  of  the  date  of  the  2017  filing  and  as  a  result 
recorded an  income tax benefit  in  2017.  The  benefit  related  to  the  remeasurement  of  certain  deferred tax assets  and 
liabilities, based on the rates at which they were expected to reverse in the future, was $43.6 million. 

8. Fair Value Measurements

The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current 
transaction between willing parties, other than in a forced sale or liquidation. Fair value estimates are made at a specific 
point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature 
and involve uncertainties and matters of judgment, and therefore cannot be determined with precision.  

Accounting standards define fair value as the price that would be received from selling an asset or paid to transfer a 
liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market 
participants at the measurement date. Accounting standards establish a fair value hierarchy which requires an entity to 
maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value and also 
establishes the following three levels of inputs that may be used to measure fair value: 

Level 1 - Quoted prices in active markets for identical assets or liabilities. 

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets
or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by 
observable market data for substantially the full term of the assets or liabilities. 

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of 
the assets or liabilities. 

The following methods and assumptions were used by the Company in estimating fair value disclosures for financial 

instruments: 

(cid:120)

Cash  and  cash  equivalents,  restricted  cash,  receivables,  and  accounts  payable:  The  amounts  reported  in  the 
accompanying Consolidated Balance Sheets approximate fair value due to their short-term nature. 

(cid:120) Debt  obligations:  The  carrying  amount  of  the  Company’s  outstanding  balance  on  its  Debt  obligations  as  of 
December 31, 2018 and 2017 was estimated to have a fair value of approximately $1,348.1 million and $1,090.0 
million, respectively,  based  on  the fair value  of  estimated  future payments  calculated using  interest rates  that 
approximate prevailing market rates at each year end. 

Assets Measured and Recorded at Fair Value on a Recurring Basis 

As of December 31, 2018 and 2017, the Company measured the fair value of its interest rate swap of $100.0 million 
(notional amount) based on Level 2 inputs, due to the usage of inputs that can be corroborated by observable market data. 
The  Company  estimates  the  fair  value  of  derivative  instruments  using  a  discounted  cash  flow  technique  and  has  used 

75 

creditworthiness inputs that corroborate observable market data evaluating the Company’s and counterparties’ risk of non-
performance. The interest rate swap agreement had a net fair value of $1.7 million and $1.1 million as of December 31, 
2018 and 2017, respectively. In 2018, 2017 and 2016, $(0.4) million, $0.6 million and $25,000, respectively, was realized 
through the income statement as an adjustment to interest expense.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis 

The Company determines fair value of long-lived assets held and used, such as Equipment held for operating lease 
and Equipment held for sale, by reference to independent appraisals, quoted market prices (e.g. an offer to purchase) and 
other  factors.  An  impairment  charge  is  recorded  when  the  carrying  value  of  the  asset  exceeds  its  fair  value.  At 
December 31, 2018 and 2017, the Company used Level 2 inputs to measure write down of equipment held for lease and 
equipment held for sale.

9. Earnings Per Share

Basic earnings per common share is computed by dividing net income by the weighted average number of common 
shares outstanding for the period. Treasury stock is excluded from the weighted average number of shares of common 
stock outstanding. Diluted earnings per share attributable to common stockholders is computed based on the weighted 
average number of shares of common stock and dilutive securities outstanding during the period. Dilutive securities are 
common stock equivalents that are freely exercisable into common stock at less than market prices or otherwise dilute 
earnings if converted. The net effect of common stock equivalents is based on the incremental common stock that would 
be issued upon the assumed exercise of common stock options and the vesting of restricted stock using the treasury stock 
method. Common stock equivalents are not included in diluted earnings per share when their inclusion is antidilutive. 
Additionally, redeemable preferred stock is not convertible and does not affect dilutive shares.  

The computations of diluted weighted average earnings per common share do not include approximately 400, 700 and 
Nil restricted shares for the year ended December 31, 2018, 2017, and 2016, respectively, as the effect of their inclusion 
would have been antidilutive to earnings per share.

Other obligations, such as certain purchase obligations are not recognized as liabilities in the consolidated financial 
statements but are required to be disclosed in the footnotes to the financial statements. These funding commitments could 
potentially  require  the  Company’s  performance  in  the  event  of  demands  by  third  parties  or  contingent  events.  As  of 
December 31, 2018, the Company had $160.2 million in purchase commitments of equipment that will be satisfied within 
one fiscal year. The purchase obligations are subject to escalation based on the closing date of each transaction. 

11. Equity

Common Stock Repurchase 

In September 2012, the Company announced that its Board of Directors authorized a plan to repurchase up to $100.0 
million of its common stock over the next 5 years. Share repurchases are retired immediately. The Board of Directors 
reaffirmed  the  repurchase  plan  in  2016  and  extended  the  Plan  to  December  31,  2018.  During  2018,  the  Company 
repurchased 471,595 shares of common stock for approximately $16.2 million under this program, at a weighted average 
price of $34.36 per share. During 2017, the Company repurchased 155,312 shares of common stock for approximately 
$3.5 million under this program, at a weighted average price of $22.83 per share. 

Effective as of December 31, 2018, the Board of Directors approved the renewal of the repurchase plan extending the 
plan through December 31, 2020 and amending the plan to allow for repurchases of up to $60 million of the Company’s 
common stock until such date.

The rights and privileges of the Preferred Stock are described below: 

Voting Rights: Holders of the Preferred Stock do not have general voting rights.

Dividends: The Company’s Series A-1 Preferred Stock and Series A-2 Preferred Stock accrue quarterly dividends at 
the  rate  per  annum  of  6.5%  per  share.  During  the  years  ended  December  31,  2018  and  2017,  the  Company  paid  total 
dividends of $3.2 million and $1.3 million, respectively, on the Series A-1 and Series A-2 Preferred Stock. 

Liquidation  Preference:  The  holders  of  the  Preferred  Stock  have  preference  in  the  event  of  any  voluntary  or 
involuntary liquidation, dissolution, or winding-up of the corporation,  including a merger or consolidation. Upon such 
liquidation  event,  the  Preferred  Stockholders  are  entitled  to  be  paid  out  of  the  assets  of  the  Company  available  for 
distribution  to  its  stockholders  after  payment  of  all  the  Company’s  indebtedness  and  other  obligations  and  before  any 
payment shall be made to the holders of common stock or any other class or series of stock ranking on liquidation junior 
to the Preferred Stock an amount equal to $20.00 per share, plus any declared but unpaid dividends. 

Redemption: The Preferred Stock has no stated maturity date, however the holders of the Preferred Stock have the 
option  to  require  the  Company  to  redeem  all  or  any  portion  of  the  Preferred  Stock  for  cash  upon  occurrence  of  any 
significant changes in operating results, ownership structure, or liquidity events as defined in the Preferred Stock purchase 
agreements.  The redemption price is $20.00 per share plus dividends accrued but not paid.  The Company is accreting the 
Preferred Stock to redemption value over the period from the date of issuance to the date first callable by the Preferred 
Stockholders (October 2023 for the Series A Preferred Stock and September 2024 for the Series A-2 Preferred Stock), 
such that the carrying amounts of the securities will equal the redemption amounts at the earliest redemption dates.

The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted on May 24, 2007. Under this 2007 Plan, a total of 
2,800,000 shares are authorized for stock based compensation available in the form of either RSA’s or stock options. The 
RSA’s are subject to service-based vesting, typically between one and four years, where a specific period of continued 
employment must pass before an award vests. The expense associated with these awards is recognized on a straight-line 
basis over the respective vesting period, with forfeitures accounted for as they occur. For any vesting tranche of an award, 
the cumulative amount of compensation cost recognized is equal to the portion of the grant-date fair value of the award 
tranche that is actually vested at that date. There are no stock options outstanding under the 2007 Plan. 

The 2018 Stock Incentive Plan (the “2018 Plan”) was adopted on May 24, 2018. Under this 2018 Plan, a total of 
800,000 shares are authorized for stock based compensation, plus the number of shares remaining under the 2007 Plan and 

78 

 
 
 
    
     
    
 
  
   
any future forfeited awards under the 2007 and 2018 Plans, in the form of RSA’s. The RSA’s are subject to service-based 
vesting, typically between one and four years, where a specific period of continued employment must pass before an award 
vests. The expense associated with these awards is recognized on a straight-line basis over the respective vesting period, 
with forfeitures accounted for as they occur. For any vesting tranche of an award, the cumulative amount of compensation 
cost recognized is equal to the portion of the grant-date fair value of the award tranche that is actually vested at that date.

As of December 31, 2018, the Company has granted 2,885,914 RSA’s under the 2007 Plan. Of this amount, 176,644 
shares were cancelled and returned to the pool of shares which could be granted under the 2018 Plan resulting in a net 
number of 890,730 shares available for future issuance. The fair value of the RSA’s equaled the stock price at the grant 
date. 

As of December 31, 2018, the Company has not granted RSA’s under the 2018 Plan.

At December 31, 2018 the stock compensation expense related to the RSA’s that will be recognized over the average
remaining vesting period of 1.8 years totaled $8.7 million. At December 31, 2018, the intrinsic value of unvested RSA’s 
was $14.5 million. 

Under the Employee Stock Purchase Plan (“ESPP”), as amended and restated effective April 1, 2018, 325,000 shares 
of common stock have been reserved for issuance. Eligible employees may designate no more than 10% of their base cash 
compensation to be deducted each pay period for the purchase of common stock under the Purchase Plan. Participants 
may purchase no more than 1,000 shares or $25,000 of common stock in any one calendar year. Each January 31 and 
July 31 shares of common stock are purchased with the employees’ payroll deductions from the immediately preceding 
six months at a price per share of 85% of the lesser of the market price of the common stock on the purchase date or the 
market price of the common stock on the date of entry into an offering period. In 2018, 2017, and 2016, 11,132, 11,485, 
and 11,014 shares of common stock, respectively, were issued under the ESPP. The Company issues new shares through 
its transfer agent upon employee stock purchase. The weighted average per share fair value of the employee’s purchase 
rights under the Purchase Plan for the rights granted was $9.42, $7.39 and $6.35 for 2018, 2017 and 2016, respectively. 

13. Employee 401(k) Plan

The  Company  adopted  The  Willis  401(k) Plan  (the  “401(k) Plan”)  effective  as  of  January 1997.  The  401(k) Plan 
provides for deferred compensation as described in Section 401(k) of the Internal Revenue Code. The 401(k) Plan is a 
contributory  plan  available  to  all  full-time  and  part-time  employees  in  the  United  States.  In  2018,  employees  who 
participated in the 401(k) Plan could elect to defer and contribute to the 401(k) Plan up to 75% of pretax salary or wages 
up to $18,500 (or $24,500 for employees at least 50 years of age). The Company matches 50% of employee contributions 

79 

 
 
 
 
 
 
 
 
 
 
 
up to 8% of the employee’s salary and capped at $12,250, which totaled $0.3 million, $0.4 million, and $0.4 million for 
the years ended December, 31, 2018, 2017, and 2016, respectively.

for lodging and other business related services.  These transactions were approved by the Board’s independent Directors

16. Reportable Segments

The  Company  operates  in  two  reportable  business  segments:  (i) Leasing  and  Related  Operations  which  involves 
acquiring  and  leasing,  primarily  pursuant  to  operating  leases,  commercial  aircraft,  aircraft  engines  and  other  aircraft 
equipment,  the  selective  purchase  and  resale  of  commercial  aircraft  engines  and  other  aircraft  equipment,  and  engine 
management and (ii) Spare Parts Sales which involves the purchase and resale of after-market engine and airframe parts, 
whole engines, engine modules and portable aircraft components. 

The  Company  evaluates  the  performance  of  each  of  the  segments  based  on  profit  or  loss  after  general  and 
administrative expenses. While the Company believes there are synergies between the two business segments, the segments 
are managed separately because each requires different business strategies. 

During the second quarter of 2018, the Company moved certain sales of leased equipment parts to the Spare Parts 
Sales segment from the Leasing and Related Operations segment and had no change in the determination of operating 
segments. In accordance with ASC 280-10, the Company has restated prior period information presented below to reflect 
this change in composition of its reportable segments.

(1) Effective January 1, 2018, the Company adopted ASC 606 – Revenue from Contracts with Customers and has identified the transfer of engines and 
airframes from the lease portfolio to the Spare Parts segment for part out as sales to customers in accordance with the ordinary operations of our 
Spare Parts reportable segment. As such, the Company presents the sale of these assets on a gross basis and have reclassified the gross revenue and 
costs on sale to the Spare parts and equipment sales and Cost of spare parts and equipment sales line items from the net gain (loss) presentation 
within the Gain on sale of leased equipment line item.  

(2) The Company adopted ASC 606 on January 1, 2018, using the modified retrospective approach applied only to contracts not completed as of the 
date of adoption, with no restatement of comparative periods. Therefore, the comparative information has not been adjusted and continues to be 
reported under ASC Topic 605 – Revenue Recognition.

17. Subsequent Events 

On December 14, 2018, the Company entered into definitive agreements with easyJet Airline Company Limited for 
the sale and leaseback of ten Airbus A319 aircraft powered by CFM56-5B engines, of which the sale and leaseback of six 
of the aircraft were completed by December 31, 2018. On January 8, 2019, the Company completed the sale and leaseback 
of the remaining four A319 aircraft powered by CFM56-5B engines.
