DEAR SHAREHOLDERS:

2017 has been an exciting and eventful year! Hopefully, 2018 

will prove to be as filled with new projects and successes. We have 

achieved many milestones:

• 

Many new customers in ever-increasing parts of the world,  

supported by our historically largest portfolio of assets.

• 

Access to new-technology engines powering the most 

modern airliners ever produced.

• 

Fully functioning and integrated management team 

covering the four corners of the world.

• 

Applied and expected benefi ts of the Tax Reform Act 

which will provide for interesting opportunities to 

expand our business. 

Going forward, we will continue to review our optimal structure, 

including the potential formation of a subsidiary to hold and manage 

the Company’s non-core assets.

Leasing 

We now own and manage nearly 700 assets for our own account as 

well as others. We have purchased over $150 million  of new engines 

in the last 90 days of the year. We invested in more equipment last 

A commercial aircraft is a vehicle 
capable of supporting itself 
aerodynamically and economically 
at the same time.

year than in any year in the company’s history, propelling us into the 

wonderful world of new technology. Currently, we are taking delivery

of powerplants for the B-737 MAX, the A320 NEO, the B-787 

Dreamliner and new engines for the A320 CEO family of aircraft. 

We will continue to make strategic acquisitions as opportunities 

become available. In concert with the above, we will also continue 

acquiring suitable aircraft, which fi t our strategic and future business 

requirements. Through all of these acquisitions, we have been able 

to keep the portfolio’s utilization high because of our deep and 

diverse customer base. 

Capital Markets 

During the summer of 2017, we again successfully accessed the 

asset-backed securitization markets. We had a very rewarding 

selection of investors, as well as favorable rates and terms that will 

allow us to manage our interest rate exposure as time goes forward. 

The ABS market is a cost-effective method of matching long-lived 

assets to long-term capital. We do not utilize this vehicle for “gain on 

sale” fi nancial treatment, but rather as a source of long-term funding 

and assisting in the laddering of our debt maturities.

Also, we sold an additional $30 million of Series A Preferred Stock. 

The stock was sold to the Development Bank of Japan, a wholly 

owned entity of the Government of Japan, which also purchased 

$20 million of our Series A Preferred Stock in 2016. We felt this was 

an important addition to our fi nancial well-being, and provides even 

greater security for our common shareholders, as well as our lending 

institutions. We continue to believe that it is benefi cial to spread our 

funding, operations and sales to many parts of the world.

Bank Markets

The bank and swap markets have been very favorable to our 

company. As interest rates increase now and in the future, we hedge 

our fl oating rate exposures with not only ABS structures, but also with 

swaps and preferred stock. We actively manage our capital structure 

to maintain signifi cant availability in our revolving credit facility. 

The swap we currently hold is “in the money” and availability of 

bank debt at favorable terms continues to be a source of greatly 

appreciated capital. We are very fortunate to have a bank group, 

including some banks who have been with us for many years, 

who are not only knowledgeable of, but also conversant in the 

international aviation fi nance business.

Engine Management and Fleet Planning 

Willis Asset Management is coming along nicely. The asset 

management business has secured many new customers and 

continues to service existing relationships that have relied on WAM 

for accurate, timely and forward-looking evaluations, data mining, 

and planning. As airlines deal with record numbers of aircraft 

Our job is...to let no 
new improvement in fl ying and 
fl ying equipment pass us by.

corporate tax rate from the Tax Cut and Jobs Act of 2017.

coming and going on and off lease, our customers have realized 

that their in-house personnel want to converse with likeminded 

experts, knowledgeable and experienced in managing technical, 

regulatory and fl eet planning challenges.  As the years progress, 

we foresee WAM becoming an increasingly important part of the 

WLFC organization.

Willis Aero

It is nearly fi ve years since WLFC acquired JT-Power through its 

subsidiary Willis Aeronautical Services, Inc. The company has steadily 

grown into a profi table, synergistic and integral part of our overall 

enterprise. We see Willis Aero continuing to grow, but not so fast or 

so big that it eclipses the main driver of the parent, that being the 

leasing business. 

Summary

Our company is moving ahead into various new areas. I fully 

support the goals and aspirations of our employees, as well as our 

Average Utilization

I am indeed fortunate to have spent my career in this fi eld.

Thank you.

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 aircraft engines owned by other 
parties. As  of  December 31,  2017,  we  had  a  total  lease  portfolio  consisting  of  225  engines  and  related  equipment,  16 
aircraft and 7 other leased parts and equipment with 80 lessees in 43 countries with an aggregate net book value of $1,342.6 
million. In addition to our owned portfolio, as of December 31, 2017, we managed a total lease portfolio of 437 engines 
and related equipment for other parties. We also seek, from time to time, to act as a leasing agent of engines 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 has been the engine management 
and consulting business of the TES Aviation Group. Willis Asset Management has 393 engines, excluding WLFC engines, 
under management as of December 31, 2017. 

We are a Delaware corporation, incorporated in 1996. Our executive offices are located at 773 San Marin Drive, 
Suite 2215,  Novato,  California  94998.  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  engines  and  aircraft  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 48,000 engines installed on commercial aircraft.  Accordingly,  we estimate  that there  are 
between 4,800 and 6,720 spare engines in the market, including both owned and leased spare engines. 

3 

 
 
 
 
 
 
 
 
 
 
 
Our  engine  portfolio  consists  of  noise-compliant  Stage  III  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,  McDonnell 
Douglas, 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). 

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.  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: 

• 

• 

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. The Centre 
for Aviation fleet database estimates that there are approximately 23,850 active commercial aircraft, and the fleet has been 
growing at a rate of 4.1% per year since 2007. Boeing projects 4.8% annual growth in the global commercial jet fleet, 
doubling  the  current  fleet  to  over  45,240  aircraft  by  2035.  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: 

• 

• 

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

the geographic scope of such aircraft operator’s destinations; 

4 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

the time an engine is on-wing between removals; 

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 capital 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,  2017,  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 aircraft equipment, in contrast to capital or financing 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-

5 

 
 
 
 
 
 
 
 
 
 
lease,  it  undergoes  inspection  to  verify  compliance  with  lease  return  conditions.  Our  management  believes  that  our 
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 enter into a new lease, sell or part out the related engines. The demand for 

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

• 

• 

• 

• 

• 

• 

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  engines  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, 2017,  we had a total lease portfolio consisting of 225 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, 2016, we 
had a total lease portfolio consisting of 208 aircraft engines and related equipment, 11 aircraft and 5 other leased parts and 
equipment, with a net book value of $1,136.6 million. 

As of December 31, 2017, minimum future rentals under non-cancelable operating leases of these engines, parts 

and aircraft assets were as follows:

As of December 31, 2017, we had 80 lessees of commercial aircraft engines and related equipment, aircraft, and 
other leased parts and equipment in 43 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  with  a  net  book  value  of  $230.3  million  as  of  December  31,  2017.  Our  investment  in  the  joint  venture  is 
$36.0 million as of December 31, 2017. 

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. We made a $15.0 million initial 
capital contribution, representing our fifty percent, up-front funding contribution to the new 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 $58.8 million as of December 31, 2017. Our investment 
in the joint venture is $14.6 million as of December 31, 2017.  

AIRCRAFT LEASING 

As of December 31, 2017, we owned and leased nine Boeing 737 aircraft, three ATR72-202 turboprops, and four 

A319-112 aircraft with an aggregate net book value of $138.2 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  of 
aircraft and engines. The launch of this new business segment in November 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, 2017, spare parts inventory had a carrying value of $16.4 million. 

WILLIS ASSET MANAGEMENT LIMITED 

In  2016,  Willis  Asset  Management  purchased  the  business  and  assets  of  TES,  the  consulting  and  asset 
management business of the TES Aviation Group.  Willis Asset Management is an asset management, technical services 
and consultancy business.  Willis Asset Management has 393 engines, excluding WLFC engines, under management as of 
December 31, 2017.

OUR COMPETITIVE ADVANTAGES 

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

•  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. 

•  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. 

•  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. 

•  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. 

•  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. 

•  We have a diverse lease portfolio by customer, geography and asset type. As of December 31, 2017, we had 
a total lease portfolio consisting of 225 engines and related equipment, 16 aircraft and 7 other leased parts 
and equipment with 80 lessees in 43 countries and an aggregate net book value of $1,342.6 million. 

•  We have a diverse lease product offering (by engine type and types of leases). We lease a variety of noise-
compliant, Stage III 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,  McDonnell  Douglas, 
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 

8 

 
 
 
 
 
 
 
 
product lines, complementary lines of business, greater financial, marketing, information systems and other resources. In 
addition,  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. 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. Some 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. 

Federal regulations stipulate that all aircraft engines hold, or be capable of holding, a noise certificate issued under 
Chapter 3 of Volume 1, Part II of Annex 16 of the Chicago Convention, or have been shown to comply with Stage III noise 
levels set out in Section 36.5 of Appendix C of Part 36 of the FAA Regulations of the United States if the engines are to 
be used in the continental United States. Additionally, much of Europe has adopted similar regulations. As of December 
31, 2017, all of the engines in our lease portfolio are Stage III 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, 2017, approximately 79% 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 2017, 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, 2017. 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.  No country 
accounted for more than 10% of our lease rent revenue in 2015. 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 WEST II or through WEST III, 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  85%  of  an  engine  purchase  price.  Substantially  all  of  our  assets  secure  our  related  indebtedness.  We  typically 
acquire engines from airlines in a sale-lease back transaction, from 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 arangements from time to time. 

EMPLOYEES 

As  of  December  31,  2017,  we  had  155  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 

We  are  affected  by  the  risks  faced  by  commercial  aircraft  operators  and  maintenance,  repair  and  overhaul 

companies (“MROs”) because they are our customers. 

Commercial aircraft operators are engaged in economically sensitive, highly cyclical and competitive businesses. 
We are a supplier to commercial aircraft operators and MROs. As a result, we are indirectly affected by all the risks facing 
commercial  aircraft  operators  and  MROs,  with  such  risks  being  largely  beyond  our  control.  Our  results  of  operations 
depend,  in  part,  on  the  financial  strength  of  our  customers  and  our  customers’  ability  to  compete  effectively  in  the 
marketplace and manage their risks. These risks include, among others: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

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; 

changes in interest rates and the availability and terms of credit available to commercial aircraft operators; 

concerns about security, terrorism, war, public health and political instability;  

inclement weather and natural disasters, including but not limited to volcanic eruptions; 

environmental compliance and other regulatory costs; 

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

aircraft fuel prices and availability; 

technological developments; 

•  maintenance costs; 

• 

• 

• 

airport access and air traffic control infrastructure constraints; 

insurance and other operating costs; 

industry capacity, utilization and general market conditions; and 

•  market prices for aviation equipment. 

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

• 

a decrease in demand for some engine types in our portfolio; 

11 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

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; and 

• 

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

Our engine values and lease rates, which are dependent on the status of the types of aircraft on which engines 

are installed, and other factors, 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. However, 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 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 from these operators 
could have an adverse effect on the demand for the affected engine types and the values of such engines. 

Upon termination of a lease, we may be unable to enter into new leases or sell the engine or its parts on acceptable 

terms. 

We directly or indirectly own the engines that we lease to customers and bear the risk of not recovering our entire 
investment through leasing and selling the engines. Upon termination of a lease, we seek to enter a new lease or to sell or 
part-out the engine. We also selectively sell engines 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 our engines coming off-lease or for their 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 are subject to the risks and costs of aircraft maintenance and obsolescence on the aircraft that we own. 

We currently own and lease nine Boeing 737 aircraft, three ATR72-202 turboprops, and four A319-112 aircraft. 
We may buy other aircraft or interests in aircraft in the future primarily to seek opportunities to realize value from the 
engines or related parts on those aircraft. Among other risks described in this Annual Report, the following risks apply 
when we lease or sell aircraft: 

•  we will be subject to the greater maintenance risks and risks of declines in value that apply to aircraft as 

opposed to engines, as well as the potentially greater risks of leasing or selling aircraft; 

• 

• 

• 

intense competition among manufacturers, lessors, part-out companies and sellers may, among other things, 
adversely affect the demand for, lease rates and residual values of our aircraft; 

our aircraft lessees are aircraft operators engaged in economically sensitive, highly cyclical and competitive 
businesses and our results of operations from aircraft leasing depend, in part, on their financial strength (for 
more details, see the risk factor above entitled “We are affected by the risks faced by commercial aircraft 
operators and MROs because they are our customers”); 

our  aircraft  lessees  may  encounter  significant  financial  difficulties,  which  could  result  in  our  agreeing  to 
amend our leases with the customer to, among other things, defer or forgive rent payments or extend lease 
terms as an alternative to repossession; 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

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 

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 and WEST III 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. Forty-six of our leases comprising approximately 26.0% of the net book value of our on-lease assets at 
December 31, 2017 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  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  engine  reserve  restricted  cash  accounts,  will  be  sufficient  to  fund  necessary  engine  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: 

• 

• 

• 

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; 

13 

 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

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

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,  unless  and  until  remedied,  and  reduce  our 
revenues and increase our expenses. If an engine is damaged during a lease and we are unable to recover from the lessee 
or though insurance, we may incur a loss. 

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: 

• 

• 

• 

• 

• 

• 

• 

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 engine utilization rates, lease margins, maintenance reserve revenues and proceeds 
from engine 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 for lease 
or  sale  periodically  experiences  cycles  of  oversupply  and  undersupply  of  given  engine  models.  The  incidence  of  an 
oversupply of engines may produce substantial decreases in engine lease rates and the appraised and resale value of engines 
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. 

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

Certain lessees may be significantly delinquent in their rental payments and may default on their lease obligations. 
As of December 31, 2017, we had an aggregate of approximately $8.3 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. 

Following the September 11, 2001 terrorist attacks and the global recession that began in 2008, the commercial 
aviation  industry  was  negatively  affected.  The  airline  industry  recovered  in  the  years  thereafter  and  has  returned  to 
profitability with some carriers even posting record profits. However, we cannot give assurance that delinquencies and 
defaults on our leases will not increase during future cyclical downturns in the economy and commercial aviation industry. 

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 

14 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 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. 

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. 

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. These Departments  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 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 

15 

 
 
 
 
 
 
 
 
 
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 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. 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. 

Any change to current tax laws or accounting principles making operating lease financing less attractive could 

adversely affect our business, financial condition and results of operations. 

Our  lessees  enjoy  favorable  accounting  and  tax  treatment  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  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 (the "FASB") issued Accounting Standards Update 
No. 2016-02, “Leases” (Topic 842). 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  U.S.  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 

16 

 
 
 
 
 
 
 
 
 
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. ASU 2016-02 is effective for interim and annual periods beginning after December 
15, 2018, with early adoption permitted, and must be adopted using a modified retrospective approach for leases that exist 
or are entered into after the beginning of the earliest comparative period in the financial statements. We plan to adopt this 
guidance on January 1, 2019, that standard’s effective date, and are currently in the process of determining the impact that 
the updated accounting guidance will have on our consolidated financial statements and related disclosures. 

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. 

We may not be adequately covered by insurance. 

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. We have not experienced any significant aviation-
related claims or any product liability claims related to our engines, aircraft or spare parts that were not insured. 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 spare parts could result in 
significant monetary claims for which there may not be sufficient insurance coverage. 

RISKS RELATING TO OUR CAPITAL STRUCTURE 

Our inability to obtain sufficient capital 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 and aircraft is dependent, in part, on the appraised value of our engines 
and  aircraft.  If  the  appraised  value  of  our  engines  and  aircraft  declines,  we  may  be  required  to  reduce  the  principal 
outstanding  under  certain  of  our  debt  facilities.  Availability  under  such  debt  facilities  may  also  be  reduced,  at  least 
temporarily, as a result of such reduced appraisals. 

The relatively recent worldwide disruptions in the credit and financial markets increased the risk of adverse effects 
on our customers and our capital providers (lenders and derivative counter-parties) and therefore on us. 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, 

17 

 
 
 
 
 
 
 
 
 
 
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. 

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: 

•  meet the terms and maturities of our existing and future debt facilities; 

• 

• 

• 

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 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 and WEST III, 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 British Bankers’ Association, the one-month LIBOR was approximately 1.57% 
and 0.77% on December 31, 2017 and December 31, 2016, 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. 

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
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.  

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—Liquidity and Capital Resources.” 

NUMEROUS FACTORS MAY AFFECT THE TRADING PRICE OF OUR COMMON STOCK 

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

• 

• 

• 

• 

• 

• 

• 

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; 

changes in accounting mandated under GAAP; 

quarterly variations in our operating results; 

our financial condition, performance and prospects; 

changes in financial estimates by us; 

19 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

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, 2017, 84% 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. 

A substantial portion 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. 

A substantial portion 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. 

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. 

20 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

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 
Engine Leasing, 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 and WEST III. Due to WEST II’s and WEST III’s bankruptcy 
remote structure, that equity is subject to the prior payments of WEST II’s and WEST III’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 or WEST III 
upon liquidation, reorganization, dissolution or winding up will be subject to the prior claims of WEST II’s or WEST III’s 
creditors. Similarly, the rights of our shareholders are subject to satisfaction of the claims of our lenders and other creditors. 

21 

 
 
 
 
 
 
 
 
 
 
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: 

• 

• 

• 

• 

• 

• 

• 

• 

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 as of December 31, 2007, completing our annual assessment of 
internal controls over financial reporting. We have complied with Section 404b of the Sarbanes-Oxley Act as of 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 
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 

22 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
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. 

As of December 31, 2017, our principal stockholder, Chairman of the Board of Directors and Chief Executive 
Officer, Mr. Charles F. Willis, IV, beneficially owned or had the ability to direct the voting of 2,756,181 shares of our 
common stock, representing approximately 43% 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 and WEST III 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 and WEST III facilities. We 
receive  monthly  fees  of  11.5%  as  servicer  (3.5%  of  which  is  subordinated  in  the  case  of  WEST  III)  and  2.0%  as 
administrative agent of the aggregate net rents actually received by WEST II and WEST III on their engines. We may be 
removed as servicer and or administrative agent in either or both of our WEST II and WEST III facilities, by an affirmative 
vote of a requisite number of either or both of the WEST II or WEST III note holders.  Such vote could happen upon the 
occurrence  of  certain  specified  events  as  outlined  in  the  WEST  II  and  WEST  III  servicing  and  administrative  agency 
agreements. 

As of December 31, 2017, we  were in compliance  with the  financial covenants  set forth in the WEST II and 
WEST III 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 and 
WEST III facilities. If we are removed from such role with those facilities, our expenses would increase as our consolidated 
subsidiaries, WEST II and WEST III, would have to hire an outside provider to 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 

23 

 
 
 
 
 
 
 
 
 
 
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 Novato, California under a lease that covers 20,534 square feet of office space.   

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.  We own 26,500 square feet of office space and 
warehouse space in Coconut Creek, FL and 30,000 square feet of office and warehouse space in Bridgend, Wales, UK. 
We also lease facilities for sales and operations in London, UK; Shanghai, China; Singapore; Blagnac, France; and Dublin, 
Ireland.

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 prohibit us from paying any dividends 
or making distributions of any kind with respect to our common stock. The Series A 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 was approved by shareholders and authorized the issuance of 2,000,000 shares of 
common stock. On May 28, 2015, the Company’s shareholders authorized an increase in the number of shares of Common 
Stock available for grant by 800,000 shares bringing the total to 2,800,000 shares authorized.  By December 31, 2017, 
there  were 2,615,960 shares  of restricted stock  granted  under the 2007 Stock Incentive  Plan. Of this amount,  166,744 
shares of restricted stock were cancelled and returned to the pool of shares which could be granted under the 2007 Stock 
Incentive  Plan  resulting  in  a  net  number  of  350,784  shares  which  were  available  as  of  December  31,  2017  for  future 
issuance under the 2007 Stock Incentive 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. The repurchased shares are immediately retired. The Board 
of Directors reaffirmed the repurchase plan in October 2016 and extended the plan to December 31, 2018.  During 2017, 
the Company repurchased 155,312 shares totaling $3.5 million under our authorized plan. As of December 31, 2017, the 
total number of common shares outstanding was approximately 6.4 million. 

Common stock repurchases, under our authorized plan, in the fourth quarter ended December 31, 2017 were as

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 
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,  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, 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 of Part I, 
“Risk Factors,” 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,  and  the  selective  sale  of  such  engines,  all  of  which  we  sometimes  refer  to  as 
“equipment.” As of December 31, 2017, all of our leases were operating leases. As of December 31, 2017, we had 80

lessees in 43 countries. Our portfolio is continually changing due to acquisitions and sales. As of December 31, 2017, our 
lease portfolio consisted of 225 engines and related equipment, 16 aircraft and 7 other leased parts and equipment with an 
aggregate  net  book  value  of  $1,342.6  million.  As  of  December  31,  2017,  we  also  managed  437  engines  and  related 
equipment on behalf of other parties.   

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

of TES.  TES has been the engine management and consulting business of the TES Aviation Group.  

In 2014 we entered into an agreement with CASC to participate in a joint venture named CASC Willis, a new 
joint venture based in Shanghai, China. Each partner holds a fifty percent interest in the joint venture. We made a $15.0 
million initial capital contribution, representing our fifty percent, up-front funding contribution to the new 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 $58.8 million as of December 31, 2017. Our 
investment in the joint venture is $14.6 million as of December 31, 2017.  

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 with a net book value of $230.3 million 
at December 31, 2017. Our investment in the joint venture is $36.0 million as of December 31, 2017. 

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 from third parties.  

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 III 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, McDonnell Douglas, 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 
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, 2017 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.   

27 

 
 
 
 
 
 
 
 
 
 
We  generally  depreciate  engines  on  a  straight-line  basis  over  15  years  to  a  55%  residual  value.  Aircraft  are 
generally depreciated on a straight-line basis over 13 to 20 years to a 15% to 17% residual value. Spare parts packages 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, 2017, 48 engines and 3 
aircraft having a net book value of $80.1 million were depreciated under this policy with estimated useful lives ranging 
from 1 to 82 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 all assets 
in our lease portfolio to determine if any impairment exists, by performing an undiscounted cash flow test for each asset. 

Impairment  is  identified  by  comparison  of  undiscounted  forecasted  cash  flows,  including  estimated  sales 
proceeds, over the life of the asset with the asset’s book value. If the forecasted undiscounted cash flows are less than the 
book value, we write the asset 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: 

•  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 Maintenance, 
Repair and Overhaul (“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 
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. 

28 

 
 
 
 
 
 
 
 
 
 
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 or the lease terminates, 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.

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 $41.1 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 
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. 

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 Tax Cuts and Jobs Act of 2017 (the “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.

Lease Rent Revenue. Our lease rent revenue for the year ended December 31, 2016 increased by 11.0% over the 
comparable period in 2015. This increase primarily reflects a  higher average portfolio utilization in the current period, 
which translated into a higher percentage of lease rent revenue earning assets. The aggregate net book value of equipment 
held for lease at December 31, 2016 and 2015, was $1,136.6 million and $1,109.2 million, respectively, an increase of 
2.5%. Portfolio utilization is defined as the net book value of on-lease assets as a percentage of the net book value of total 
lease assets. As of December 31, 2016 and 2015, approximately 93% and 90%, respectively, of equipment by net book 
value was on-lease. The average utilization for the year ended December 31, 2016 was 90% compared to 87% in the prior 
year. 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). During the year ended December 31, 2015, 12 engines and 6 aircraft were 
added to our lease portfolio at a total cost of $172.7 million (including capitalized costs). 

Maintenance Reserve Revenue. Our maintenance reserve revenue for the year ended December 31, 2016 increased 
6.9%  to  $57.1  million  from  $53.4  million  for  the  comparable  period  in  2015.  The  increase  was  due  to  both  higher 
utilization, driving a $5.7 million increase in short term maintenance revenues partially offset by $2.0 million of lower 
maintenance reserve revenues related to a lower termination of long term leases in the year ended December 31, 2016 than 
in the year ago period.   

Spare Parts and Equipment Sales. Spare parts and equipment sales for the year ended December 31, 2016 was 
$17.8 million compared to $25.6 million in 2015. Equipment sales of $3.3 million were for the sale of three airframes 
during the year ended December 31, 2016.  Equipment sales were $10.0 million for the sale of two airframe, one engine 
and related equipment for the year ended December 31, 2015. Spare parts sales for the year ended December 31, 2016 
were $14.5 million compared to $15.6 million in the comparable period in 2015.   

Gain on Sale of Leased Equipment. During the year ended December 31, 2016, we sold 7 engines and various 
engine-related equipment from the lease portfolio for a net gain of $3.5 million. During the year ended December 31, 2015, 
we sold 8 engines and various engine-related equipment from the lease portfolio for a net gain of $8.3 million. 

Other Revenue. Other revenue increased $6.3 million from the prior year primarily due to recognizing revenue of 
$4.0 million of security payments for aircraft upon default of a lessee and $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 decreased $3.1 million or 4.5% 
to $66.3 million for the year ended December 31, 2016, from the comparable period in 2015 primarily due to changes in 
portfolio mix associated with our ongoing portfolio management efforts.

Cost of Spare Parts and Equipment Sales. Cost of spare parts and equipment sales for the year ended December 
31, 2016 was $13.3 million a decrease of 25.5% from the comparable period in 2015.  Cost of equipment sales was $2.4 
million and $5.7 million in the year ended December 31, 2016 and 2015, respectively. Cost of spare parts sales for the year 
ended December 31, 2016 were $10.7 million compared to $12.1 million in the comparable period in 2015.  Gross margin 
on spare parts sales for 2016 was 24.6% compared to 22.4% for 2015 primarily due to a change in the mix of parts sold in 
2016.   

Write-down of Equipment. Write-down of equipment to their estimated fair values totaled $9.5 million for the 
year ended December 31, 2016, an increase of $0.3 million from the $9.2 million recorded in the comparable period in 
2015. A writedown 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. 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 writedown 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. 

A write-down of equipment totaling $9.2 million was recorded in the year ended December 31, 2015. This amount 
includes a write-down of equipment totaling $5.5 million due to a management decision to consign four engines for part-
out and sale, in which the assets’ net book value exceeded the estimated proceeds from part-out. Write-downs on held for 
use equipment to their estimated fair values totaled $0.6 million for the year ended December 31, 2015 due to an adjustment 
of carrying values for certain impaired parts packages within the portfolio to reflect estimated market values. A further 
write-down of $2.8 million was recorded in the year ended December 31, 2015 to adjust the carrying value of engine parts 
for which market conditions for the sale of parts has changed. An additional write-down of $0.3 million was recorded in 
the year ended December 31, 2015 based on a comparison of the inventory values with the revised net proceeds expected 
from part sales. 

General and Administrative Expenses. General and administrative expenses increased 11.8% to $47.8 million for 
the year ended December 31, 2016, from the comparable period in 2015 due primarily to increases in contingency bonus 
($3.1 million) resulting from improved operating results (pre-tax earnings and utilization) as well as increases in salary 
expense ($1.4 million) from increased headcount, and higher legal expenses ($1.0 million). 

Technical Expense. These expenses decreased 25.6% to $7.0 million for the year ended December 31, 2016, from 
the comparable period in 2015 due primarily to a decrease in engine maintenance costs due to reduced engine shop visits 
($1.4 million) lower engine thrust rental fees ($0.7 million), and lower engine technical services expense ($0.3 million) 
due to decreased engine returns. 

Net Finance Costs. Net finance costs increased 9.0% to $41.3 million for 2016, from the comparable period in 
2015, due primarily to higher average debt balances in the current period compared to the year ago period and the recording 
of a gain on debt extinguishment of $1.2 million in the prior year period. The average notes payable balances for the years 
ended December 31, 2016 and 2015 were $892.4 million and $858.2 million, respectively, an increase of 4.0%.  As of 
December 31, 2016, $619.7 million of our debt is tied to one-month U.S. dollar LIBOR which increased from an average 
of 0.21% for 2015 to an average of 0.45% for 2016 (average of month-end rates). At December 31, 2016 and 2015, one-
month LIBOR was 0.77% and 0.43%, respectively.  

To mitigate  exposure to interest rate  changes,  we  periodically enter into interest rate  swap agreements.  As of 
December 31, 2016, such swap agreement had a notional outstanding amount of $100.0 million, with a remaining term of 
52 months. No interest rate swap agreements existed during the year ended December 31, 2015. 

Income Taxes. Income tax expense for the year ended December 31, 2016, increased to $9.9 million from $6.3 
million for the comparable period in 2015. The effective tax rate for the years ended December 31, 2016 and December 
31,  2015  were  41.2%  and  49.4%,  respectively.  This  decrease  was  due  to  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, 2016.

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. 

LIQUIDITY AND CAPITAL RESOURCES 

We  finance our  growth through borrowings secured by our equipment lease portfolio.  Cash of approximately 
$686.2 million, $149.0 million and $192.7 million, in the years ended December 31, 2017, 2016, and 2015, respectively, 
was derived from this borrowing activity.  In these same time periods $496.2 million, $114.0 million and $153.8 million, 
respectively, was used to pay down related debt. Cash flow from operating activities generated $124.9 million, $122.1 
million and $139.5 million in the years ended December 31, 2017, 2016, and 2015, respectively. Also in 2017 and 2016 
we generated $29.7 million and $19.8 million, respectively, of cash from the sale of preferred stock. 

At  December  31,  2017,  $2.3  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. 

Our primary use of funds is for the purchase of equipment for lease. Purchases of equipment (including capitalized 
costs and prepaid deposits) totaled $384.0 million, $173.7 million and $174.8 million for the years ended December 31, 
2017, 2016, and 2015, respectively. 

During 2017, we received $1.9 million in distributions from our investment in WMES.  During 2016,  we made 
$5.5 million of capital contributions and received $1.2 million in distributions from our investment in WMES. During 
2017, we  received $1.3 million in distributions  from our investment in CASC Willis.  During 2016, distributions  from 
CASC Willis were nil and no capital contributions were made. 

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 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 89% and 93%, by book value, of our assets were on-lease as of December 
31, 2017 and December 31, 2016, respectively. The decline in percentage year over year is a direct result of purchases 
made during the fourth quarter of 2017, a large portion of which were not on-lease. The average utilization rate for the 
year ended December 31, 2017 and 2016 was approximately 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. 

At December 31, 2017, debt obligations consists of loans totaling $1,085.4 million 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 the "Debt Obligations" Note 4 in Part II, Item 8 of  this 
Form 10-K. 

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. 

33 

 
 
 
 
 
 
 
 
 
At  December  31,  2017,  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. As defined in the revolving credit facility agreement, the Interest Coverage Ratio is the ratio 
of Earnings before Interest, Taxes, Depreciation and Amortization and other one-time charges (EBITDA) to Consolidated 
Interest Expense, and the Total Leverage Ratio is the ratio of Total Indebtedness to Tangible Net Worth. At December 31, 
2017, we are in compliance with the covenants specified in the WEST II and WEST III indentures, servicing and other 
related agreements. 

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 our contractual commitments at December 31, 2017:

We have estimated the interest payments due under debt obligations by applying the interest rates applicable at 
December 31, 2017 to the remaining debt, adjusted for the estimated debt repayments identified in the table above. Actual 
interest payments made will vary due to changes in the rates for one-month LIBOR. 

We believe our equity base, internally generated funds and existing debt facilities are sufficient to maintain our 
level  of  operations  through  2018.  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, 2017, $501.3 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 
entered  into  one  interest  rate  swap  agreement  which  has  notional  outstanding  amount  of  $100.0  million,  which  has  a 
remaining term of 40 months as of December 31, 2017. The fair value of the swap at December 31, 2017 and 2016 was 
$1.1 million and $68,000, 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  increased  interest  expense  by  $0.6  million,  $25,000,  and  Nil  for  the  years  ended  December  31,  2017, 
December 31, 2016 and December 31, 2015, 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. 

RELATED PARTY TRANSACTIONS 

Stock Buybacks 

On April 1, 2016, in a transaction approved by a Special Committee of the Board of Directors, the Company 
purchased 60,000 shares of its common stock directly from the Company’s Chief Executive Officer, Charles F. Willis. 
The purchase price was $20.59 per share, the closing price of the Company’s common stock as of March 31, 2016. 

On December 8, 2016, in a transaction approved by a Special Committee of the Board of Directors, the Company 
purchased 40,000 shares of its common stock directly from the Company’s Chief Executive Officer, Charles F. Willis. 
The  purchase  price  was  $24.95  per  share,  a  2%  discount  to  the  closing  price  of  the  Company’s  common  stock  as  of 
December 8, 2016 of $25.46. 

Joint Ventures 

“Other revenue” on the Consolidated Statement of Income includes management fees earned of $2.4 million, $2.1 
million and $1.7 million during the years ended December 31, 2017, 2016 and 2015, respectively, related to the servicing 
of engines for the WMES lease portfolio. 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 

Throughout the year, the Company accrued approximately $80,000 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, 2017, $501.3 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 $4.0 million (in 2016, $5.2 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. 

35 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are also exposed to currency devaluation risk. During the years ended December 31, 2017, 2016, and 2015, 
respectively,  84%,  89%  and  92%  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. 

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. 

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, 
2017.  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, 2017, our internal control over financial reporting is effective under those 
criteria.

likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Shareholders 
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, 2017 and 2016, 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, 2017, 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, 2017, 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, 2017 and 2016, and the results of its operations and its cash flows for each 
of the years in the three-year period ended December 31, 2017, 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, 2017, 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 

43 

 
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 

(a)  Organization 

Willis Lease Finance Corporation with its subsidiaries (the “Company”) 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. WLFC (Ireland) Limited, WLFC Funding (Ireland) Limited and WLFC Lease 
(Ireland)  Limited  are  wholly-owned  Irish  subsidiaries  of  the  Company  formed  to  facilitate  certain  of  the  Company’s 
international  leasing  activities.  Willis  Aviation  Finance  Limited  in  Ireland  is  a  wholly-owned  subsidiary  formed  to 
facilitate  the  leasing  and  technical  support  of  worldwide  activities.  Willis  Lease  France  is  a  wholly-owned  French 
subsidiary of the Company formed to facilitate sales and marketing activities in Europe. Willis Lease (China) Limited is a 
wholly-owned subsidiary of the Company formed to facilitate the acquisition and leasing of assets in China. 

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 Engine Acquisition LLC and Facility Engine Acquisition LLC are wholly-owned subsidiaries of WEST II and own 
the engines which secure the notes issued by WEST II. Willis Engine Securitization (Ireland) Limited is another wholly-
owned subsidiary of WEST II and was established to facilitate certain international leasing activities by WEST II.  WEST 
II is a variable interest entity which the Company owns 100% of the equity and consolidates in its financial statements. 

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 from third parties 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 Asset Management has 393 engines, excluding 
WLFC engines, under management as of December 31, 2017. 

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 WEST III Notes are secured by a portfolio of 56 engines from the revolving credit facility. 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 
variable interest entity which the Company owns 100% of the equity and consolidates in its financial statements.   

The assets and liabilities of WEST III will remain on the Company’s balance sheet. A portfolio of 56 commercial 
jet aircraft engines and leases thereof 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  transactions  described  above,  the  Company  entered  into  a  Servicing  Agreement  and 
Administrative Agency Agreement with WEST III to provide certain engine, lease management and reporting functions 

50 

 
 
 
 
 
 
 
 
 
   
 
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.  

The assets of WEST III are not available to satisfy the Company’s obligations other than the obligations specific 
to  WEST  III.  WEST  III  is  consolidated  for  financial  statement  presentation  purposes.  WEST  III’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 
III’s maintenance of adequate reserves and capital. Under WEST III, 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. 
Minimum maintenance reserve payments and security deposits of $10.0 million and $1.0 million, respectively, are held in 
restricted cash accounts. 

(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  variable  interest  entities  (“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 

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. 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. 

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 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 engine are not included in the sale, any such amount is included in the calculation of gain or loss. 

The Company evaluates sales arrangements under Financial Accounting Standards Board (“FASB”) Accounting 
Standards Codification (“ASC”) 605-25, Revenue Recognition: Multiple Element Arrangements (“FASB ASC 605-25”), 
which addresses accounting for multiple element arrangements. The Company has determined that two deliverables, the 
sale  of  equipment  and  the  management  services,  are  separate  units  of  accounting.  Therefore, revenue  is  recognized  in 
accordance with FASB ASC 605-10-S99, Revenue Recognition: Overall: SEC Materials, formerly SAB 104, for each unit.  

For  multiple  deliverable  revenue  arrangements,  the  Company  allocates  revenue  to  equipment  sales  and 
management services using the relative selling price method to recognize revenue when the revenue recognition criteria 
for each deliverable are met. The selling price of a deliverable is based on a hierarchy and if the Company is unable to 
establish vendor-specific objective evidence of selling price (“VSOE”) it uses third-party evidence of selling price (“TPE”), 
and if no such data is available, it uses a best estimated selling price (“BSP”). The objective of BSP is to determine the 
price at which the Company would transact a sale if the equipment or service were sold on a stand-alone basis.  

For management services, the selling price is based on TPE and is determined by reviewing information from 
management agreements entered into by other parties on a standalone basis which is then compared to the management 
agreements entered into with the investor group. The Company has determined that the fees charged on a standalone basis 

51 

   
 
 
 
 
 
 
 
 
 
are comparable to the fees charged when the Company enters into the management agreements concurrent with the sale of 
a  portfolio  of  engines.  Accordingly,  the  Company  determined  that  the  fees  charged  for  its  management  services  are 
comparable to those charged by other asset managers for the same service. 

The Company recognizes revenue from management fees under equipment management agreements as earned 
on a monthly basis. Management fees are based upon a percentage of net lease rents of the investor group’s engine portfolio 
calculated on an accrual basis and recorded in Other revenue. 

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  or  the  lease 
terminates, 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, 2017, the Company had an aggregate of approximately $8.3 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 lease 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 
management  believes  full  collection  is  doubtful;  and  (2) a  general  reserve  for  estimated  losses  based  on  historical 
experience. 

The Company recognizes sales of spare parts upon shipping and the amount reported as cost of sales is recorded 

at specific cost. 

The  Company  recognizes  service  revenue  from  fees  earned  under  engine  maintenance  service  agreements  as 

earned on a monthly basis.  

No customer accounted for greater than 10% of total lease rent revenue in 2017, 2016 and 2015. 

(d)  Other Revenue 

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.  

(e)  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 

52 

 
 
 
 
 
 
 
 
 
 
 
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 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 spare parts packages 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. 

For 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. 

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, 2017, 48 engines and 3 aircraft having a net book value of $80.1 million were depreciated under this policy 
with  estimated  useful  lives  ranging  from  1  to  82  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 comparison of 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 $4.4 million, $1.8 million and $0.6 million in 2017, 2016, and 
2015, respectively (included in “Write-down of equipment” in the Consolidated Statements of income).   

(f)  Equipment Held for Sale 

Equipment  held  for  sale  includes  engines  being  marketed  for  sale  as  well  as  engines  removed  from  the  lease 
portfolio to be parted out, with the investment in the long lived asset being recovered through the sale of spare parts. The 
assets to be disposed are reported at the lower of carrying amount or fair value less costs to sell. 

 (g)  Debt Issuance Costs and Related Fees 

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

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

(h) 

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 

53 

 
 
 
 
 
 
 
 
 
 
 
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. 

(i) 

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 6). 

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. 

(j)  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 fifteen 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. 

(k)  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. 

(l)  Restricted Cash  

The  Company  has  certain  bank  accounts  that  are  subject  to  restrictions  in  connection  with  our  WEST  II  and 
WEST III borrowings. Under both 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,  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, 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. 

(m)   Spare Parts Inventory 

Inventory consists of  spare aircraft and engine parts and 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. 

54 

 
 
 
 
 
 
 
 
 
 
 
 
(n)   Intangible Assets 

Intangible assets include customer relationships and goodwill arising from the Company’s acquisitions of J.T. 
Power and TES.  Intangible assets are accounted for in accordance with FASB 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. 

(o) Other assets 

Other  assets  typically  include  prepaid  deposits,  capitalized  costs  relating  to  engine  shop  visits  that  remain  in 
process at year end, and other prepaid expenses. As of December 31, 2017, other assets included prepaid deposits of $36.5 
million relating to a commitment to purchase engines. 

(p)   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. 

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. 

(q)   Earnings per share information 

Basic earnings per share is computed by dividing net income by the weighted average number of common shares 
outstanding for the period. Diluted earnings per share is computed by dividing net income by the weighted average number 
of shares outstanding, adjusted for the dilutive effect of stock options and unvested restricted stock awards. See Note 8 for 
more information on the computation of earnings per share. 

(r) 

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. 

55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(s)  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.  

(t)  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 $1.8 million, $1.6 million and $1.6 million for the years ended December 31, 2017, 2016 and 2015, respectively. 

(u)  Maintenance Rights 

The  Company  identifies,  measure  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. 

(v) 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. 

(w) 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.

(x) Recent Accounting Pronouncements 

Recent Accounting Pronouncements Adopted by the Company 

In July 2015, the FASB  issued Accounting Standards Update ("ASU")  2015-11, Simplifying the Measurement 
of Inventory, which simplifies the measurement of inventory by requiring certain inventory to be measured at the lower of 
cost or net realizable value. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016 
and for interim periods therein.  The Company adopted ASU 2015-11 on January 1, 2017 and it did not have a material 
impact on the consolidated financial statements.  

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements 
to Employee Share-Based Payment Accounting. The standard is intended to simplify several areas of accounting for share-
based  compensation  arrangements,  including  the  income  tax  impact,  classification  on  the  statement  of  cash  flows  and 
forfeitures.  The  Company  adopted  ASU  2016-09  on  January  1,  2017,  the  standard’s  effective  date,  on  a  modified 
retrospective  method through a cumulative adjustment to  retained earnings of $1.3 million. During the the year ended 
December 31, 2017, excess tax benefits from stock-based compensation of approximately $91,000 were reflected in the 
Consolidated Statements of Income as income taxes, whereas they previously were recognized in equity. Additionally, the 
Consolidated Statements of Cash Flows now present excess tax benefits as an operating activity, with the prior periods 
adjusted accordingly. The Company has elected to account for forfeitures as they occur, rather than estimate expected 
forfeitures. As a result of the adoption of ASU 2016-09, the Consolidated Statement of Cash Flows for the years ended 
December 31, 2016 and 2015 were adjusted as follows: a $0.2 million and Nil, respectively, increase to net cash provided 
by operating activities and a $0.2 million and Nil, respectively, decrease to net cash provided by financing activities. 

In November 2016, the FASB issued ASU 2016-18, Restricted Cash, which requires amounts generally described 
as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total 
beginning and ending amounts for the periods shown on the statement of cash flows. ASU 2016-08 is effective for fiscal 
years beginning after December 15, 2017 (including interim periods within those periods) using a retrospective transition 
method to each period presented. The Company adopted this standard during on January 1, 2017 and included $64.1 million 
and $22.3 million of restricted cash in the total of cash, cash equivalents and restricted cash in its statements of consolidated 
cash flows for the year ended December 31, 2016 and 2015, respectively. The adoption of this standard also resulted in an 
decrease in cash provided by operating activities, cash used in investing activities and cash provided by financing activities 
of $10.7 million, $1.3 million and $1.3 million, respectively, for the year ended December 31, 2016 and $9.6 million, $16.8 
million and $25.4 million, respectively, for the year ended December 31, 2015. 

Recent Accounting Pronouncements To Be Adopted by the Company:  

In May 2014, the FASB issued 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 not in a contract with a customer (for example, sales of real estate) to be consistent with the 
standard’s guidance on recognition and 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. 

This  accounting  standard  update  is  effective  for  reporting  periods  beginning  after  December  15,  2017.  The 
Company adopted this accounting standard update effective January 1, 2018. The amendments in this accounting standard 

57 

 
 
 
 
 
   
 
update must be applied using either of the following transition methods: (i) a full retrospective approach reflecting the 
application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a 
modified retrospective approach  with the cumulative effect of initially adopting the standard recognized at the date  of 
adoption (which requires additional footnote disclosures). Effective January 1, 2018, the Company adopted the standard 
using the  modified retrospective  approach applied only to  contracts  not completed as of the date  of adoption,  with  no 
restatement of comparative periods and a cumulative effect adjustment recognized as of the date of adoption.  

While only a portion of the Company’s revenues are 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 will be 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 Other revenue) were evaluated, and similar performance obligations will result under the 
new standard as compared with deliverables and separate units of accounting currently identified. In addition the Company 
considered recognition under the new standard and concluded the timing of the Company’s revenue recognition will remain 
the same. 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. 

In February 2016, the FASB issued ASU No. 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 U.S. 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. ASU 2016-02 is effective for interim 
and  annual  periods  beginning  after  December  15,  2018,  with  early  adoption  permitted,  and  must  be  adopted  using  a 
modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative 
period in the financial statements. The Company plans to adopt this guidance on January 1, 2019, that standard’s effective 
date,  and  is  currently  in  the  process  of  determining  the  impact  that  the  updated  accounting  guidance  will  have  on  the 
consolidated  financial  statements  and  related  disclosures.  See  Note  9  for  a  summary  of  undiscounted  minimum  rental 
commitments under operating leases as of December 31, 2017. 

In January 2017, the FASB issued ASU 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying 
the  Test  for  Goodwill  Impairment,”  that  eliminates  “Step  2”  from  the  goodwill  impairment  test.  The  new  standard  is 
effective  in  the  first  quarter  of  fiscal  2020,  and  early  adoption  is  permitted.  The  new  guidance  must  be  applied  on  a 
prospective basis. The Company does not anticipate that the adoption of this standard will have a significant impact on the 
consolidated financial statements or the related disclosures.  

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 becomes effective for the Company 
in  the  first  quarter  of  fiscal  2018.  The  new  guidance  must  be  applied  on  a  prospective  basis.  The  Company  does  not 
anticipate that the adoption of this standard will have a significant 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”  to  address 
stakeholder concerns about the guidance in current U.S. 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.  The 

58 

 
   
   
   
 
Company  is  currently  evaluating  the  timing,  methods  and  impact  of  adopting  this  new  standard  on  the  consolidated 
financial statements.

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. WMES owned a lease portfolio of 32 engines with a net book value of 
$230.3 million as of December 31, 2017. 

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. The  Company made a 
$15.0  million  initial  capital  contribution,  representing  the  fifty  percent,  up-front  funding  contribution  to  the  new  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 4 engines with a net book value of $58.8 million as of December 31, 2017.

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 covenant requirements at December 31, 2017. 

At December 31, 2017, 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, 2017 and 2016, $399.0 million and $282.0 
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 and WEST III 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, 2017,  $330.7 million of WEST III term notes were outstanding.  The assets of WEST III are 
not  available  to  satisfy  the  Company’s  obligations  other  than  the  obligations  specific  to  WEST  III.  WEST  III  is 
consolidated for financial statement presentation purposes. WEST III’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 III’s maintenance of adequate 
reserves and capital. Under WEST III, 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 III indenture requires 
that a minimum threshold of maintenance reserve and security deposit balances be held in restricted cash accounts. 

At December 31, 2017 and 2016, $259.0 million and $279.5 million of WEST II term notes were outstanding, 
respectively.  The  assets  of  WEST  II  are  not  available  to  satisfy  the  Company’s  obligations  other  than  the  obligations 
specific to WEST II. WEST II is consolidated for financial statement presentation purposes. WEST II’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 
II’s maintenance of adequate reserves and capital. Under WEST II, 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, the WEST II indenture requires that a portion of maintenance reserve payments and all lease security deposits 
be  held  in  restricted  accounts  and  are  available  to  fund  future  maintenance  events  and  to  secure  lease  payments, 
respectively.  

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 as of September 14, 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 the second quarter 
of 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 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 $12.7 million and $14.5 million as December 31, 
2017 and December 31, 2016, respectively. 

In January 2014, the Company extended the term of an existing loan that was scheduled to mature in January 
2015. The loan had a term of 4 years and was subsequently repaid at the maturity date in January 2018. Interest was payable 
at one-month LIBOR plus 2.25% and principal and interest was paid quarterly. The loan was secured by  three engines. 
The balance outstanding on this loan was $10.3 million and $11.7 million as of December 31, 2017 and December 31, 
2016, respectively. 

In  March  2015,  the  Company  paid  off  the  $23.1  million  balance  of  two  term  notes  at  a  5%  discount.  This 
transaction  resulted  in  the  recording  of  a  $1.2  million  gain  on  debt  extinguishment  which  has  been  included  in  the 
Consolidated Statement of Income for the year ended December 31, 2015. 

 (5) Derivative Instruments 

The Company periodically holds interest rate derivative instruments to mitigate exposure to changes in interest 
rates, in particular one-month LIBOR, with $501.3 million and $619.7 million of borrowings at December 31, 2017 and 
2016, 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 40 months as of December 31, 2017. The fair value of the swap at December 31, 2017 

63 

 
 
 
 
 
 
  
 
 
and 2016  was  $1.1 million and  $68,000, respectively, representing a net asset. The Company recorded a  $0.6 million, 
$25,000 and nil expense to net finance costs during the three years ended December 31, 2017, 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.

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, 2017 and December 31, 2016 for the exposure in Europe. If the 
Company is able to eventually recognize these uncertain tax positions, all of the unrecognized benefit would reduce the 
Company’s effective tax rate.

As of December 31, 2017, the Company had net operating loss carry forwards of approximately $138.0 million 
for federal tax purposes and $1.0 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 2023 
to  2037.  During  2014,  a  valuation  allowance  of  $1.3  million  was  established  for  the  net  operating  losses  expiring  in 
California for the periods 2017 to 2024. 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 382 of the 
Internal Revenue Code and similar state tax law. As of December 31, 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 2014-2017 and 
2013-2017, respectively. 

The decrease in the Company’s valuation allowance is related to the increase in California’s state apportionment 
percentage  due  to  the  Company’s  increased  leases  with  US  airlines,  in  particular  to  the  2015  spare  engine  support  of 
Southwest’s fleet of Boeing 737NG aircraft.  As a result of this increase, the Company is able to utilize the California net 
operating losses (“NOL’s”) and reduce the valuation allowance. 

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “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 has calculated the impact of the Act in the year end 
income tax provision in accordance with management’s understanding of the Act and guidance available as of the date of 
this filing and as a result have recorded a $39.6 million  income tax benefit in the fourth quarter of 2017, the period in 
which the legislation was enacted. The amount related to the remeasurement of certain deferred tax assets and liabilities, 
based on the rates at which they are expected to reverse in the future, was $43.6 million, which reduced the fourth quarter 
tax expense of $4 million to a benefit of $39.6 million. 

(7) 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: 

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

•  Debt  obligations:  The  carrying  amount  of  the  Company’s  outstanding  balance  on  its  Debt  obligations  as  of 
December 31, 2017 and 2016 was estimated to have a fair value of approximately $1,090.0 million and $864.0 
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, 2017 and 2016, 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 
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 $1.1 million and $68,000 as of December 31, 2017 
and  2016,  respectively.  In  2017, 2016  and 2015,  $0.6  million,  $25,000  and  nil,  respectively,  was  realized  through  the 
income statement as an increase in 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,  2017  and  2016,  the  Company  used  Level  2  inputs  to  measure  write  down  of  equipment  held  for  lease, 
equipment held for sale, and spare parts inventory.

Write-downs of equipment to their estimated fair values totaled $24.9 million for the year ended December 31, 
2017 which included write-downs of $16.9 million for the adjustment of the carrying value of nine impaired engines and 
$4.7 million to adjust the carrying value of five impaired aircraft within the portfolio to reflect estimated market value.  

 A writedown 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. 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 writedown 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.  

(8) 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 do not include approximately 700, Nil and 
4,300 restricted shares for the year ended December 31, 2017, 2016, and 2015, 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, 2017,  the  Company  had  $124.0  million  in  purchase  commitments  of  engines  that  will  be 
satisified  within  one  fiscal  year.  The  purchase  obligations  are  subject  to  escalation  based  on  the  closing  date  of  each 
transaction.

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

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 Series A Preferred Stock and Series A-2 Preferred Stock carry quarterly dividends at the rate per 
annum of 6.5% per share. During 2017, the Series A Preferred Stock paid total dividends of $1.3 million. The first dividend 
for the Series A-2 Preferred Stock totaled $0.6 million and was paid on January 15, 2018. 

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

significant changes in operating results, ownership structure, or liqudity 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 significant stock compensation plans are described below. 

The 2007 Stock Incentive Plan (the “2007 Plan”) was adopted on May 24, 2007. Under this 2007 Plan, a total of 
2,000,000  shares  are  authorized  for  stock  based  compensation  available  in  the  form  of  either  restricted  stock  awards 
(“RSA’s”) or stock options.  On May 28, 2015, the Company’s shareholders authorized an increase in the number of shares 
of Common Stock available for grant by 800,000 shares bringing the total to 2,800,000 shares authorized. 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.  With  the  modified  retrospective  adoption  of  ASU  2016-09  on  January  1,  2017,  the 
Company no longer reduces stock-based compensation by estimated forfeitures and instead accounts for forfeitures when 
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,  2017,  the  Company  has  granted  2,615,960  RSA’s  under  the  2007 Plan.  Of  this  amount, 
166,744 shares were cancelled and returned to the pool of shares which could be granted under the 2007 Plan resulting in 
a net number of 350,784 shares available as of December 31, 2017 for future issuance. The fair value of the restricted stock 
awards equaled the stock price at the date of grants.

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 2017, 2016, and 2015, 11,485, 11,014,
