DEAR SHAREHOLDERS,

Thanks to solid execution of our strategic imperatives and our management team’s self-disciplined 

approach to creating lasting value for our Customers, I am proud to announce 2017 was a noteworthy  

year for Allison Transmission.

Looking back at our achievements, we met or exceeded financial performance expectations, improved 

our profitability, substantially grew our net sales and made strategic investments in our business. We 

also prudently managed our capital structure with opportunistic refinancing activities, repurchased 

$885 million of common stock and made payments of quarterly dividends to shareholders. I’m proud 

of our team’s performance and the resourcefulness they demonstrated throughout the year 

during rapidly changing market conditions. 

Full year 2017 results exceeded our initial Net Sales guidance ranges across all of our end markets. 

Since becoming a standalone company, we achieved record levels of Net Sales at $2,262 

million, a 23 percent increase over 2016. This net sales increase translated into an Adjusted 

EBITDA of $868 million, or a 35 percent increase over the previous year. Adjusted Free Cash 

Flow for the year was $567 million compared to $530 million in 2016.

Allison Transmission is a well-balanced commercial, defense, and engineering-based propulsion 

solution provider. Our strengths are derived from our proven ability to leverage our most  

valuable assets—our people, our technology, our manufacturing capabilities and our unrelenting 

focus on creating value for our Customers.

Lawrence E. Dewey, Chairman and CEO

I am also proud to report that Allison realized its second consecutive

efficiencies and lower cost.

LOOKING TOWARD THE FUTURE

Autonomous driving and smart mobility offer realistic opportunities 

to further optimize the commercial trucking industry through 

“truck platooning.” There are cost advantages to this innovative 

system of logistics. However, the fundamentals of successful truck 

platooning rely heavily on the vehicles’ communications and 

controls—and that’s where Allison has excelled for many years. 

Allison’s 5th Generation electronic controls and their proprietary 

software have exceeded expectations and we are already working 

on future evolutions of these capabilities. Allison intends to play an 

important role in this exciting transportation trend. We expect to 

be ready to respond with the right products at the right time.

ALLISON TRANSMISSION / 2017 ANNUAL REPORT

THE POWER OF ALLISON TRANSMISSION

Allison Transmission is the world’s largest manufacturer of fully 

automatic transmissions for medium- and heavy-duty commercial 

vehicles and we are recognized for our best-in-class products by an 

increasingly demanding Customer base. By our estimates in 2017, we 

continue to hold the largest portion of the fully automatic transmission 

business in the end markets we serve. 

The Allison team never loses sight of those who depend on us. We 

know that in many cases it is our dedication to excellence that makes 

the difference for both our commercial and defense Customers. We 

continue to be proud of our employees, not only for their professionalism, 

capabilities and skills, but also for their character and integrity. 

Collectively, we are gratified our Customers continue to ask for our 

products by name.

THE GROUNDWORK IS IN PLACE TO GROW OUR MARKET SHARE          AND DELIVER PERFORMANCE TO ALL OF OUR STAKEHOLDERS.

OUR GOALS FOR 2018 ARE CLEAR:

•  Continue to develop innovative products that Customers value 
•  Grow our market share outside North America 
•  Continue to build a corporate culture that embraces challenges 

and responds quickly to evolving market needs—our Customers’ 

priorities will be our priorities 
•  Produce strong financial results 

As Allison Transmission’s next Chief Executive Officer, I would like to 

acknowledge Larry Dewey’s many years of dedicated service and acting 

in the best long-term interests of Allison as being truly exceptional, and 

I thank him for it. We all appreciate his work ethic, resilience, creativity 

and integrity. Larry Dewey led us through his words and his deeds. 

He established standards and performance that separate Allison from 

virtually any other industrial enterprise by never accepting that we  

are too successful to set another goal or imagine a better reality. 

Larry Dewey’s focus will remain our focus—deliver on our commitments 

because our success begins and ends with our performance.

PART I. 

ITEM 1. Business   

Overview  

Allison Transmission Holdings, Inc. and its subsidiaries (“Allison,” the “Company” or “we”) design and manufacture 
commercial and defense fully-automatic transmissions. The business was founded in 1915 and has been headquartered 
in Indianapolis, Indiana since inception. Allison was an operating unit of General Motors Corporation from 1929 until 2007, 
when Allison once again became a stand-alone company. In March 2012, Allison began trading on the New York Stock 
Exchange under the symbol, “ALSN”.  

We have approximately 2,700 employees and 13 different transmission product lines. Although approximately 79% 
of revenues were generated in North America in 2017, we have a global presence by serving customers in Europe, Asia, 
South America and Africa. We serve customers through an independent network of approximately 1,400 independent 
distributor and dealer locations worldwide.  

Our Business  

We are the world’s largest manufacturer of fully-automatic transmissions for medium- and heavy-duty commercial 

vehicles and medium- and heavy-tactical U.S. defense vehicles. Allison transmissions are used in a wide variety of 
applications, including on-highway trucks (distribution, refuse, construction, fire and emergency), buses (primarily school, 
transit and electric hybrid-transit), motorhomes, off-highway vehicles and equipment (primarily energy, mining and 
construction) and defense vehicles (wheeled and tracked). We estimate that globally, in 2017, we sold approximately 60% 
of all fully-automatic transmissions for medium- and heavy-duty on-highway commercial vehicle applications. We believe 
the Allison brand is one of the most recognized in our industry as a result of the performance, reliability and fuel efficiency 
of our transmissions and is associated with high quality, durability, vocational value, technological leadership and superior 
customer service. 

We introduced the world’s first fully-automatic transmission for commercial vehicles over 60 years ago. Since that 

time, we have driven the trend in North America and Western Europe towards increasing automaticity by targeting a 
diverse range of commercial vehicle vocations. Allison transmissions are optimized for the unique performance 
requirements of end users, which typically vary by vocation. Our products are highly engineered, requiring advanced 
manufacturing processes, and employ complex software algorithms for our transmission controls to maximize end user 
performance. We have developed over 100 different models that are used in more than 2,500 different vehicle 
configurations and are compatible with more than 500 combinations of engine brands, models and ratings (including 
diesel, gasoline, natural gas and other alternative fuels).  Additionally, we have created thousands of unique Allison-
developed calibrations available to be used with our transmission control modules. 

Our Industry  

Commercial vehicles typically employ one of three transmission types: manual, automated manual transmissions 

(“AMT”) or fully-automatic. Manual transmissions are the most prevalent transmission type used in Class 8 tractors in 
North America and in medium- and heavy-duty commercial vehicles, generally, outside North America. Manual 
transmissions utilize a disconnect clutch causing power to be interrupted during each gear shift resulting in energy loss-
related inefficiencies and less work being accomplished for a given amount of fuel consumed. In long-distance trucking, 
this power interruption is not a significant factor, as the manual transmission provides its highest degree of fuel economy 
during steady-state cruising. However, steady-state cruising is only one part of the duty cycle. When the duty cycle 
requires a high degree of “start and stop” activity or speed transients, as is common in many vocations as well as in urban 
environments, we believe manual transmissions result in reduced performance, lower fuel efficiency, lower average speed 
for a given amount of fuel consumed and inferior ride quality. Moreover, the clutches must be replaced regularly, resulting 
in increased maintenance expense and vehicle downtime. Manual transmissions also require a skilled driver to operate 
the disconnect clutch when launching the vehicle and shifting gears. AMTs are manual transmissions that feature 
automated operation of the disconnect clutch. Fully-automatic transmissions utilize technology that smoothly shifts gears 
instead of a disconnect clutch, thereby delivering uninterrupted power to the wheels during gear shifts and requiring 
minimal driver input. These transmissions deliver superior acceleration, higher productivity, increased fuel efficiency, 
reduced operating costs, less driveline shock and smoother shifting relative to both manual transmissions and AMTs in 
vocations with a high degree of “start and stop” activity, as well as in urban environments.  

3 

  
 
 
 
 
 
 
Emerging technologies in commercial-duty transmissions and powertrains include dual clutch transmissions (“DCT”) 

and electric drive powertrains. DCTs are variants of manual transmissions and AMTs that incorporate a “dual clutch” 
mechanism to facilitate shifting the manual transmission gearbox. Electric drive powertrains are also emerging in certain 
end markets, such as transit buses, and are in part driven by efforts to reduce fuel consumption and greenhouse gas 
emissions. Electric drive powertrains differ from “electric hybrid” powertrains because they only propel the vehicle with an 
electric motor; while “electric hybrids” generally utilize both a conventional internal combustion power source and 
powertrain as well as the means to propel the vehicle electrically. While both emerging technologies are gaining use in 
niche automotive markets, they are just beginning to evolve and become proven in commercial vehicle markets.  

Fuel efficiency, reduction in fuel consumption and reduced emissions are important considerations for commercial 

vehicles everywhere and they tend to go together.  We believe fuel efficiency, the measure of work performed for a given 
amount of fuel consumed, is the best method to assess fuel consumption of commercial vehicles as compared to the 
more commonly-used fuel economy metric of miles-per-gallon (“MPG”). MPG is inadequate for commercial vehicles 
because it does not encompass two key elements of efficiency that we believe are important to vehicle owners and 
operators: payload and transport time. For example, if more work can be completed or more payload hauled using the 
same amount of fuel and/or over a shorter period of time, then we believe the vehicle is more fuel efficient. Since fuel 
economy only accounts for distance traveled and fuel consumed, ignoring time and work performed, we believe it is 
therefore an inferior metric to fuel efficiency when it comes to assessing commercial vehicles. Markets, regulations, 
policies and technology continue to evolve with respect to these topics. 

Our Served Markets  

We sell our transmissions globally for use in medium- and heavy-duty on-highway commercial vehicles, off-highway 
vehicles and equipment and defense vehicles. In addition to the sale of transmissions, we also sell branded replacement 
parts, support equipment and other products necessary to service the installed base of vehicles utilizing our 
transmissions. The following table provides a summary of our business by end market, for the fiscal year ended

North America  

On-Highway.  We are the largest manufacturer of fully-automatic transmissions for the on-highway medium- and 

heavy-duty commercial vehicle market in North America. The following is a summary of our on-highway net sales by 
vehicle class in North America. 

Our core North American on-highway market includes Class 4-5, Class 6-7 and Class 8 straight trucks, conventional 

transit, shuttle and coach buses, school buses and motorhomes. Class 8 trucks are subdivided into two markets: straight 
and tractor. Class 8 straight trucks are those with a unified body (e.g., refuse, construction, and dump trucks), while 
tractors have a vehicle chassis that is separable from the trailer they pull. We have been supplying transmissions for 
Class 8 straight trucks for decades, and it is a core end market for us. Today, we have very limited exposure to the Class 
8 line-haul tractor market because lower priced manual transmissions and AMTs generally meet the needs of these 
vehicles which are primarily used in long distance hauling. However, we have identified a portion of the Class 8 tractor 
market that we call metro tractors that are used in urban environments the majority of the time and developed a fully-
automatic transmission (the “TC10”) that meets the unique duty cycle requirements of the Class 8 metro tractor market. 
Combining the startability and continuous, uninterrupted power qualities of a fully-automatic transmission with the cruising 
aspects of a manual transmission, the TC10 offers an alternative to traditional manual and automated manual 
transmissions in tractor applications.  

We sell substantially all of our transmissions in the North American on-highway market to OEMs. These OEMs, in 

turn, install our transmissions in vehicles in which our transmission is either the exclusive transmission available or is 
specifically requested by end users. In 2017, OEM customers representing over 95% of our North American on-highway 
unit volume participated in long-term supply agreements (“LTSA”) with us. Generally, these LTSAs offer the OEM 
customer defined levels of mutual commitment with respect to growing Allison’s presence in the OEMs’ products and 
promotional efforts, pricing and sharing of commodity cost risk. The length of our LTSAs is typically between three and 
five years. We often compete in this market against independent manufacturers of manual transmissions, AMTs, DCTs, 
electric drive systems, fully-automatic transmissions manufactured by Ford Motor Company (“Ford”), ZF Friedrichshafen 
AG (“ZF”) and Voith GmbH, and against vertically integrated OEMs in certain weight classes that use their own internally 
manufactured transmissions in certain vehicles.  

The following table presents a summary of our competitive position by vehicle class in the North America on-

highway end market.

state and federal governmental entities. In this market, we compete primarily with BAE Systems plc and manufacturers of 
electric drive systems. 

Off-Highway.  We have provided products used in vehicles and equipment that serve energy, mining and 

construction applications in North America for over 60 years. Off-highway energy applications include hydraulic fracturing 
equipment, well-stimulation equipment, pumping equipment, and well-servicing rigs, which often use a fully-automatic 
transmission to propel the vehicle and drive auxiliary equipment. We maintain a leadership position in this end market, 
with nearly all producers of well-stimulation and well-servicing equipment utilizing our heavy duty off-highway 
transmissions. Competition includes Caterpillar Inc. (“Caterpillar”) and Twin Disc, Inc. (“Twin Disc”).  

We also provide heavy-duty transmissions used in mining trucks, specialty vehicles and construction vehicles. 
Mining applications include trucks used to haul various commodities and other products, including rigid dump trucks, 
underground trucks and long-haul tractor trailer trucks with load capacities between 40 to 110 tons. Our major competitors 
in this end market are Caterpillar and Komatsu Ltd. (“Komatsu”), both of which are vertically integrated and manufacture 
fully-automatic transmissions for their own vehicles. Specialty vehicles using our heavy-duty transmissions include airport 
rescue and firefighting vehicles and heavy-equipment transporters. Our major competitor in this end market is Twin Disc. 
Construction applications include articulated dump trucks, with Caterpillar, Volvo Group (“Volvo”) and ZF as competitors. 

Outside North America  

Outside North America we serve several different markets, including: Europe, Middle East, Africa (“EMEA”), Asia-

Pacific, South America and India.  

On-Highway.  We are the largest manufacturer of fully-automatic transmissions for the commercial vehicle market 

outside of North America. While the use of fully-automatic transmissions in the medium- and heavy-duty commercial 
vehicle market has been widely accepted in North America, the markets outside North America continue to be dominated 
by manual transmissions. In 2017, fully-automatic transmission-equipped medium- and heavy-duty commercial vehicles 
represented less than 5% of the vehicles in markets outside North America and are concentrated in certain vocational end 
markets. The following is a summary of our on-highway net sales by region outside of North America.  

Europe, Middle East, Africa.  EMEA is composed of several different markets, each of which differs from our core 

North American market by the degree of market maturity, sophistication and acceptance of fully-automatic transmission 
technology. Within Europe, we serve Western European developed markets, as well as Russian and Eastern European 
emerging markets, principally in the refuse, emergency, bus, coach, distribution and utility markets. Competition in 
Western Europe is most notably characterized by a high level of vertical powertrain integration with OEMs often utilizing 
their own manual transmissions and AMTs in their vehicles. The Middle East and Africa regions are generally 
characterized by very limited local vehicle production, with imports from the U.S., South America, Turkey, China, India and 
Europe accounting for the majority of vehicles.  

6 

  
 
 
Asia-Pacific.  Our key Asia-Pacific markets include China, Japan, India, and South Korea; however, we actively 
participate in several other important Asia-Pacific countries including Australia, Taiwan, Indonesia, Malaysia and Thailand, 
which are primarily importers of commercial vehicles. Within Asia-Pacific, our sales efforts are principally focused on the 
transit bus and vocational truck markets. Currently, manual transmissions are the predominant transmissions used in 
commercial vehicles in the Asia-Pacific region.  

South America.  The South American region is characterized by a high level of OEM integration, with captive 
manual transmission and AMT manufacturing. Currently, manual transmissions are the predominant transmissions used 
in commercial vehicles in South America.   

Off-Highway.  The following is a summary of our off-highway net sales by region outside of North America. 

Europe, Middle East, Africa.  Our off-highway markets in EMEA are mining and construction. Our major off-
highway competitors are Caterpillar and Komatsu, both of which are vertically integrated manufacturers of off-highway 
mining vehicles, including the specific fully-automatic transmission used in their mining trucks. A typical construction 
application is the articulated dump truck, with competition from Caterpillar, Volvo and ZF transmissions.  

Asia-Pacific.  Off-highway markets in Asia are shared by energy, mining and construction applications. Our primary 

competitors are Caterpillar, Danyang Winstar Auto Parts Co., Ltd. and Twin Disc in energy applications, Caterpillar, 
Komatsu and Danyang Winstar Auto Parts Co., Ltd. in mining applications and Caterpillar, Volvo and ZF in construction 
applications. 

Defense  

We have a long-standing relationship with the U.S. Department of Defense (“DOD”) dating back to 1946, when we 

began developing our first-generation tank transmission. Today, we sell substantially all of the transmissions for medium- 
and heavy-tactical wheeled vehicle platforms including the Family of Medium Tactical Vehicles, Armored Security 
Vehicles, Heavy Expanded Mobility Tactical Trucks, Heavy Equipment Transporters, Palletized Loading Systems, M915 
Series Trucks, Medium Tactical Vehicle Replacements and the Logistic Vehicle System Replacement. Additionally, we 
supplied transmissions for the majority of Mine-Resistant Ambush Protected (“MRAP”) Vehicles, the MRAP All-Terrain 
Vehicle and the Joint Light Tactical Vehicle, which is the replacement vehicle for Humvee personnel transport. 
Transmissions for our wheeled vehicle platforms are typically sold to OEMs.  

We are also the supplier on two of the three key tracked vehicle platforms, the Abrams tank and the M113 family of 

vehicles, which are sold directly to the DOD. Additionally, we sell parts kits to licensees for the production of transmissions 
for tracked vehicles manufactured outside North America. See Part I, Item 1A, “Risk Factors” of this Annual Report on 
Form 10-K for a discussion of risks associated with our contracts with the U.S. DOD. 

Globally, we face competition for the supply of our transmissions in tracked defense vehicles primarily from L3 
Technologies, Inc., Renk AG and ZF. Additionally, we face limited competition from Caterpillar and ZF in certain defense 
wheeled vehicle platforms.

Service Parts, Support Equipment and Other  

The aftermarket provides us with a relatively stable source of revenues as the installed base of vehicles and 
equipment utilizing our transmissions continues to grow. The need for replacement parts is driven by normal vehicle and 
equipment maintenance requirements. Uninterrupted operation is generally critical for end users’ profitability. End users 
focus on getting the vehicle or equipment back in service, which in some cases results in the aftermarket purchase 
decision being less price-sensitive.  

The sale of Allison-branded parts and fluids, remanufactured transmissions and support equipment is fundamental 

to our brand promise. We have assembled a worldwide network of approximately 1,400 independent distributor and 
dealer locations to sell, service and support our transmissions. As part of our brand strategy, our distributors and dealers 
are required to sell genuine Allison-branded parts. Within the aftermarket, we offer remanufactured transmissions under 
our ReTran brand, which provides a cost-effective alternative for transmission repairs and replacements. We also provide 
support equipment to our OEMs to assist in installing new Allison transmissions into vehicles, and, therefore, sales of 
support equipment are dependent upon sales of new transmissions. The competition for service parts and ReTran 
transmissions comes from a variety of smaller-scale companies sourcing non-genuine “will-fit” parts from unauthorized 
manufacturers. These “will-fit” parts often do not meet our product specifications, and therefore may be of lesser quality 
than genuine Allison parts.

Product Development and Engineering  

We maintain product development and engineering capability dedicated to the design, development, refinement and 
support of our fully-automatic transmissions and electric hybrid-propulsion systems. We believe our customers expect our 
products to provide unparalleled performance and value defined in various ways, including delivering maximum cargo in 
minimum time, using the least amount of fuel possible while employing the fewest vehicles possible and experiencing 
maximum vehicle uptime. In response to those needs and the evolving customer focus on fuel efficiency, we provide 
vehicle specification guidelines, transmission control software and mechanical components to optimize fuel economy 
while delivering desired vehicle performance. Further, we are developing new technology to improve fuel efficiency and 
fuel economy by allowing engines to operate more efficiently and at lower speeds to avoid consuming fuel without 
compromising performance. Building on our engineering capabilities, we pioneered electric hybrid-propulsion in 
commercial vehicles and are developing new alternative technologies for use in our global commercial vehicle markets. 
For the years ended December 31, 2017, 2016 and 2015, we have invested $105 million, $88 million and $93 million in 
engineering – research and development, respectively. From time to time, we also acquire certain licenses to provide us 
with technology to complement our portfolio of products and product initiatives. 

Sales and Marketing Organization  

Our sales and marketing effort is organized along geographic and customer lines and is comprised of marketing, 

sales and service professionals, supported by application engineers worldwide. In North America, selling efforts in the on-
highway end market are organized by distributor area responsibility, OEM sales and, for our large end users, national 
accounts. Outside North America, we manage our sales, marketing, service and application engineering professionals 
through regional areas of responsibility. These regional management teams distribute OEM service and application 
engineering resources globally. We manage our defense products sales, marketing, service and application engineering 
through professionals based in Indianapolis, Indiana and Detroit, Michigan.  

We have developed a marketing strategy to reach OEM customers as well as end users. We target our end users 

primarily through marketing activities by our sales staff, who directly call on end users and attend local trade shows, 
targeting specific vocations globally and through our plant tour programs, where end users may test our products on the 
Indianapolis test track and our enhanced customer experience demonstration track at our Hungary facility. 

While our marketing management uses the term “customer” interchangeably for OEMs and end users, the primary 

objective of our marketing strategy is to create demand for fully-automatic transmissions through:  

•   OEM promotion of our products and incorporation of fully-automatic transmissions in their commercial vehicle 
  product offerings;  

•   Allison representative and/or Allison distributor contact with identified, major end users; and  
•   Our network of independent dealers who contact other end users.  

The process is interactive, as Allison representatives, Allison distributors, OEMs and dealers educate customers and 

respond to the specific applications, requirements and needs of numerous specialty markets.  

 Similarly, we work with customers, dealers and OEMs to educate, improve and simplify how they specify vehicles 
and vehicle systems in order to optimize vehicle performance and fuel consumption. Our field organization also works 
closely with distributors who, in turn, work with dealers to provide end users with education, parts, service and warranty 
support. The defense marketing group follows a defined plan that identifies country, vehicle and specific OEMs and then 
approaches the ultimate end user through a variety of channels.  

Manufacturing  

Our manufacturing strategy provides for distributed capability in manufacturing and assembly of our products for the 

global commercial vehicle market. Our primary manufacturing facilities, located in Indianapolis, Indiana, consist of 
approximately 2.3 million square feet of usable manufacturing space in six plants. We also have established 
customization and parts distribution in the United States, The Netherlands, Brazil, China, Hungary, India and Japan, and 
plants in Chennai, India and Szentgotthard, Hungary. Our high volume on-highway products are produced in multiple 
global locations while off-highway, electric hybrid-propulsion and defense tracked and wheeled products are produced in 
Indianapolis. 

11 

  
 
Suppliers and Raw Materials  

A significant amount of the part numbers that make up our transmissions are purchased from outside suppliers, and 

during 2017, we purchased approximately $735 million of direct materials and components from outside suppliers. The 
largest elements of our direct spending are aluminum and steel castings and forgings that are formed by our suppliers into 
our larger components and assemblies for use in our transmissions. However, our spending on aluminum and steel raw 
materials directly and indirectly through our purchase of these components constituted approximately 11% of our direct 
material and component costs in 2017. The balance of our direct and indirect materials and components costs are 
primarily composed of value-added services and conversion costs. Our supply contracts, along with an intensive supplier 
selection and performance monitoring process, have enabled us to establish and maintain close relationships with 
suppliers and have contributed to our overall operating efficiency and quality.  

Intellectual Property  

Patents and other proprietary rights are important to the continued success of our business. We also rely upon trade 

secrets, know-how, continuing technological innovation and licensing opportunities to develop and maintain our 
competitive position. We protect our proprietary rights through a variety of methods, including confidentiality agreements 
and proprietary information agreements with suppliers, employees, consultants and others who may have access to 
proprietary information. We own over 400 issued patents worldwide, and we have licensing arrangements with respect to 
more than 600 additional patents and patent applications. We have more than 400 pending patent applications throughout 
the world that relate to aspects of the technology incorporated in many of our products.  

We have an irrevocable, royalty-free, worldwide license of more than 250 U.S. and foreign patents and patent 

applications, as well as certain unpatented technology and know-how, owned by General Motors Company (“GM”) to 
manufacture, use and sell fully-automatic transmissions and certain electric hybrid-propulsion systems for use in 
vocational and defense vehicles and off-highway products. Such licenses are subject to certain limitations. See Part I, 
Item 1A, “Risk Factors” of this Annual Report on Form 10-K for a discussion of these risks and limitations. We also 
acquired from GM an irrevocable, royalty-free, worldwide license under computer software programs that we use to run 
our business, including product design. In addition, GM has a license to use certain Allison trademarks. 

Seasonality  

Overall, the demand for our products is relatively consistent over the year. However, in typical market conditions, the 
North American truck market experiences a higher level of production in the first half of the year due to fewer holidays and 
the practice of plant shutdowns in July and December. Working capital levels do not fluctuate significantly in the normal 
course for our business.  

Employees  

As of December 31, 2017, we had approximately 2,700 employees, with approximately 89% of those employees in 

the U.S. Approximately 59% of our U.S. employees are represented by the International Union, United Automobile, 
Aerospace and Agricultural Implement Workers of America (“UAW”) and are subject to a collective bargaining agreement.  
In December 2017, we entered into a six year collective bargaining agreement with UAW Local 933 that expires in 
November 2023. As approximately 39% of our represented employees are currently retirement eligible, we anticipate a 
shift toward increasing the number of multi-tier employees over the coming years. There have been no strikes or work 
stoppages due to Allison-specific issues in over 30 years.  

12 

  
 
Environmental Compliance 

We are subject to a variety of federal, state, local and foreign environmental laws and regulations, including those 

governing the discharge of pollutants into the air or water, the management and disposal of hazardous substances or 
wastes, and the cleanup of contaminated sites. Some of our operations require environmental permits and controls to 
prevent and reduce air and water pollution. These permits are subject to modification, renewal and revocation by issuing 
authorities. In addition, certain of our products and our customer’s products are subject to certification requirements by a 
variety of regulatory bodies. We believe we are in substantial compliance with all material environmental laws and 
regulations applicable to our plants and operations. Historically, our annual costs of achieving and maintaining compliance 
with environmental, health and safety requirements have not been material to our results.  

Increasing global efforts to control emissions of carbon dioxide, methane, ozone, nitrogen oxide and other 

greenhouse gases and pollutants, as well as the shifting focus of regulatory efforts towards total emissions output, have 
the potential to impact our facilities, costs, products and customers. The U.S. Environmental Protection Agency (“EPA”) 
has taken action to control greenhouse gases from certain stationary and mobile sources. In addition, several states have 
taken steps, such as adoption of cap and trade programs or other regulatory systems, to address greenhouse gases. 
There have also been international efforts seeking legally binding reductions in emissions of greenhouse gases. These 
developments and further actions that may be taken in the U.S. and in other countries, states or provinces could affect our 
operations both positively and negatively (e.g., by affecting the demand for or suitability of some of our products).  

We also may be subject to liability as a potentially responsible party under the Comprehensive Environmental 
Response, Compensation and Liability Act and similar state or foreign laws for contaminated properties that we currently 
own, lease or operate or that we or our predecessors have previously owned, leased or operated, and sites to which we 
or our predecessors sent hazardous substances. Such liability may be joint and several so that we may be liable for more 
than our share of any contamination, and any such liability may be determined without regard to causation or knowledge 
of contamination. We or our predecessors have been named potentially responsible parties at contaminated sites from 
time to time. We do not anticipate our liabilities relating to contaminated sites will be material to our results.  

In January 2016, we assumed all responsibility for operating, monitoring and maintaining the ongoing activities at 
our Indianapolis, Indiana manufacturing facilities relating to historical soil and ground water contamination. We entered 
into an administrative order of consent with the EPA that requires us to provide financial assurance to complete the 
operation, monitoring and maintenance in the event we fail to do so. In December 2016, we issued a letter of credit to the 
EPA in the amount of $15 million. 

Competition  

We compete on the basis of product performance, quality, price, distribution capability and service in addition to 

other factors. We face competition from numerous manufacturers of various types of transmissions for commercial 
vehicles. We also face competition from manufacturers in our international operations and from international 
manufacturers entering our domestic market. Furthermore, we face an increasing amount of competition from vertical 
integration, as some of our customers are OEMs that manufacture transmissions for their own products, and from 
powertrains that do not require a transmission. Despite their transmission manufacturing capabilities, our existing OEM 
customers have chosen to purchase certain transmissions from us due to the quality, reliability and strong brand of our 
transmissions and in order to limit fixed costs, minimize production risks and maintain company focus on commercial 
vehicle design, production and marketing.

ITEM 1A. Risk Factors 

The following is a cautionary discussion of risks, uncertainties and assumptions that we believe are significant to our 

business. In addition to the factors discussed elsewhere in this Annual Report on Form 10-K, the following are the 
important factors that, individually or in the aggregate, we believe could make our actual results differ materially from 
those described in any forward-looking statements. 

Risks Related to Our Business 

We participate in markets that are competitive, and our competitors’ actions could have a material adverse 
effect on our business, results of operations and financial condition.  

Our business operates in competitive markets. We compete against other existing or new global manufacturers of 

transmissions for commercial vehicles on the basis of product performance, quality, price, distribution capability and 
service in addition to other factors. In addition, we compete with manufacturers developing alternative technologies, 
including electric drivetrains, that may or may not require a transmission. Actions by our competitors could lead to 
downward pressure on prices and/or a decline in our market share, either or both of which could adversely affect our 
results.  

In addition, some of our customers or future customers are OEMs that manufacture or could in the future 

manufacture transmissions for their own products. Despite their transmission manufacturing capabilities, our existing OEM 
customers have chosen to purchase certain transmissions from us due to customer demand, resulting from the quality of 
our transmission products and in order to reduce fixed costs, eliminate production risks and maintain company focus. 
However, we cannot be certain these customers will continue to purchase our products in the future. Increased levels of 
production insourcing by these customers could result from a number of factors, such as shifts in our customers’ business 
strategies, acquisition by a customer of another transmission manufacturer, the inability of third-party suppliers to meet 
specifications and the emergence of low-cost production opportunities in foreign countries. As a result, these OEMs may 
use transmissions produced internally or by another manufacturer and no longer choose to purchase transmissions from 
us. A significant reduction in the level of external sourcing of transmission production by our OEM customers could 
significantly impact our net sales and cash flows and, accordingly, have a material adverse effect on our business, results 
of operations and financial condition.  

Certain of our end users operate in highly cyclical industries, which can result in uncertainty and significantly 
impact the demand for our products, which could have a material adverse effect on our business, results of 
operations and financial condition.  

Some of the markets in which we operate, including energy, mining, construction, distribution and motorhomes, 
exhibit a high degree of cyclicality. Decisions to purchase our transmissions are largely a result of the performance of 
these and other industries we serve. If demand for output in these industries decreases, the demand for our products will 
likely decrease. Demand in these industries is impacted by numerous factors including prices of commodities, rates of 
infrastructure spending, housing starts, real estate equity values, interest rates, consumer spending, fuel costs, energy 
demands, municipal spending and commercial construction, among others. Increases or decreases in these variables 
globally may significantly impact the demand for our products, which could have a material adverse effect on our 
business, results of operations and financial condition. If we are unable to accurately predict demand, we may be unable 
to meet our customers’ needs, resulting in the loss of potential sales, or we may manufacture excess products, resulting in 
increased inventories and overcapacity in our production facilities, increasing our unit production cost and decreasing our 
operating margins. 

Volatility in and disruption to the global economic environment and changes in the regulatory and business 
environments in which we operate may have a material adverse effect on our business, results of operations 
and financial condition.  

The commercial vehicle industry as a whole has been more adversely affected by volatile economic conditions than 
many other industries, as the purchase or replacement of commercial vehicles, which are durable items, can be deferred 
for many reasons, including reduced spending by end users. Future changes in the regulatory and business environments 
in which we operate may adversely affect our ability to sell our products or source materials needed to manufacture our 
products. Furthermore, financial instability or bankruptcy at any of our suppliers or customers could disrupt our ability to 
manufacture our products and impair our ability to collect receivables, any or all of which may have a material adverse 
effect on our business, results of operations and financial condition. In addition, some of our customers and suppliers may 
experience serious cash flow problems and, thus, may find it difficult to obtain financing, if financing is available at all. As 
a result, our customers’ need for and ability to purchase our products or services may decrease, and our suppliers may 
increase their prices, reduce their output or change their terms of sale. Any inability of customers to pay us for our 
products and services, or any demands by suppliers for different payment terms, may materially and adversely affect our 
results of operations and financial condition. Furthermore, our suppliers may not be successful in generating sufficient 

14 

  
 
sales or securing alternate financing arrangements, and therefore may no longer be able to supply goods and services to 
us. In that event, we would need to find alternate sources for these goods and services, and there is no assurance we 
would be able to find such alternate sources on favorable terms, if at all. Any such disruption in our supply chain could 
adversely affect our ability to manufacture and deliver our products on a timely basis, and thereby affect our results of 
operations.  

Our long-term growth prospects and results of operations may be impaired if the rate of adoption of fully-
automatic transmissions in commercial vehicles outside North America does not increase.  

Our long-term growth strategy depends in part on an increased rate of automaticity outside North America. As part 

of that strategy, we have established manufacturing facilities in India and Hungary. We have also dedicated significant 
human resources to serve markets where we anticipate increased adoption of automaticity, including China, India, Brazil 
and Russia. However, manual transmissions remain the market leader outside North America and there can be no 
assurance that adoption of automatic transmissions will increase. Factors potentially impacting adoption of automatic 
transmissions outside of North America include the large existing installed base of manual transmissions, customer 
preferences for manual transmissions, commercial vehicle OEM vertical integration into manual transmission and AMT 
manufacturing, increased competition from AMTs, DCTs, electric driving systems, and other alternative transmission 
technologies and failure to further develop the Allison brand. If the rate of adoption of fully-automatic transmissions does 
not increase as we have anticipated, our long-term growth prospects and results of operations may be impaired. 

Our sales are concentrated among our top five OEM customers and the loss or consolidation of any one of 
these customers or the discontinuation of particular vehicle models for which we are a significant supplier 
could reduce our net sales and have a material adverse effect on our results of operations and financial 
condition.  

We have in the past and may in the future derive a significant portion of our net sales from a relatively limited 
number of OEM customers. For the years ended December 31, 2017, 2016 and 2015, our top five customers accounted 
for approximately 49%, 52% and 52% of our net sales, respectively. Our top three customers, Daimler AG, PACCAR Inc. 
and Volvo Group, accounted for approximately 20%, 9% and 8%, respectively, of our net sales during 2017. The loss of, 
or consolidation of, any one of these customers, or a significant decrease in business from, one or more of these 
customers could harm our business. In addition, the discontinuation of particular vehicle models for which we are a 
significant supplier could reduce our net sales and have a material adverse effect on our results of operations. 

We may not be successful in introducing our new products and technologies and responding to customer 
needs.  

We currently have new products and technologies under development. The development of new products and 
technologies is difficult and the timetable for commercial release is uncertain, and we may not be successful in introducing 
our new products and responding to customer needs. In addition, it often takes significant time, in some cases multiple 
fleet buy cycles, before customers gain experience with new products and technologies and those new products and 
technologies become widely-accepted by the market, if at all. If we do not adequately anticipate the changing needs of our 
customers by developing and introducing new and effective products and technologies on a timely basis, our competitive 
position and prospects could be harmed. If our competitors are able to respond to changing market demands and adopt 
new technologies more quickly than we do, demand for our products could decline, our competitive position could be 
harmed, and we will not be able to recoup a return on our development investments. Moreover, changing customer 
demands as well as evolving safety and environmental standards could require us to adapt our products and technologies 
to address such changes. As a result, in the future we may experience delays in the introduction of some or all of our new 
products or modifications or enhancements of existing products. Furthermore, there may be production delays due to 
unanticipated technological setbacks, which may, in turn, delay the release of new products to our end users. If we 
experience significant delays in production, our net sales and results of operations may be materially adversely affected.   

Our success depends on continued research and development efforts, the outcome of which is uncertain.  

Our success depends on our ability to improve the efficiency and performance of our transmissions, and we invest 

significant resources in research and development in order to do so. Nevertheless, the research and development 
process is time-consuming and costly, and offers uncertain results. We may not be able through our research and 
development efforts to keep pace with improvements in transmission-related technology of our competitors, and licenses 
for technologies that would enable us to keep pace with our competitors may not be available on commercially reasonable 
terms if at all. Finally, our research and development efforts, and generally our ability to introduce improved products in 
the marketplace, may be constrained by the patents and other intellectual property rights of competitors and others.  

Our sales to the Defense end market are to government entities and contractors for the U.S. and foreign 
governments, and the loss of a significant number of our contracts, or budgetary declines or future reductions 

15 

  
 
or changes in spending by the U.S. or foreign governments could have a material adverse effect on our results 
of operations and financial condition.  

Our net sales to the Defense end market are derived from contracts (revenue arrangements) with agencies of, and 

prime system contractors for, the U.S. government and foreign governments. If a significant number of our DOD contracts 
and subcontracts are simultaneously delayed or cancelled for budgetary, performance or other reasons, it would have a 
material adverse effect on our results of operations and financial condition. Approximately 5%, or $117 million, of our net 
sales for the year ended December 31, 2017 were from our Defense end market.  

Our future financial results may be adversely affected by:  

• declines in, or uncertainty regarding, U.S. or foreign government defense budgets; 

• curtailment of the U.S. government’s use of technology or other services and product providers, including 

curtailment due to government budget reductions, future government shutdowns and related fiscal matters; 

• geopolitical developments that affect demand for our products and services; and 

• technological developments that impact purchasing decisions or our competitive position.  

Increases in cost, disruption of supply or shortage of raw materials or components used in our products could 
harm our business and profitability.  

Our products contain various raw materials, including corrosion-resistant steel, non-ferrous metals such as 

aluminum and nickel, and precious metals such as platinum and palladium. We use raw materials directly in 
manufacturing and in transmission components that we purchase from our suppliers. We generally purchase components 
with significant raw material content on the open market. The prices for these raw materials fluctuate depending on 
market conditions. Volatility in the prices of raw materials such as steel, aluminum and nickel could increase the cost of 
manufacturing our products. We may not be able to pass on these costs to our customers, and this could have a material 
adverse effect on our business, results of operations and financial condition. Even in the event that increased costs can 
be passed through to customers, our gross margin percentages would decline. Additionally, our suppliers are also subject 
to fluctuations in the prices of raw materials and may attempt to pass all or a portion of such increases on to us. In the 
event they are successful in doing so, our margins would decline.  

In 2017, approximately 75% of our total spending on components was sourced from approximately 38 suppliers, 
some of which are the single source for such components. All of the suppliers from which we purchase materials and 
components used in our business are fully validated suppliers, meaning the suppliers’ manufacturing processes and 
inputs have been validated under a production part approval process (“PPAP”). Furthermore, there are only a limited 
number of suppliers for certain of the materials used in our business, such as corrosion-resistant steel. As a result, our 
business is subject to the risk of additional price fluctuations and periodic delays in the delivery of our materials or 
components if supplies from a validated supplier are interrupted and a new supplier, if one is available, must be validated 
or materials and components must be purchased from a supplier without a completed PPAP, which could increase our 
risk of purchasing non-conforming components. Any such price fluctuations or delays, if significant, could harm our 
profitability or operations. In addition, the loss of a supplier could result in significant material cost increases or reduce our 
production capacity. We also cannot guarantee we will be able to maintain favorable arrangements and relationships with 
these suppliers. An increase in the cost or a sustained interruption in the supply or shortage of some of these raw 
materials or components that may be caused by a deterioration of our relationships with suppliers or by events such as 
natural disasters, power outages, labor strikes, or the like could negatively impact our business, results of operations and 
financial condition. Although we have agreements with many of our customers that we will pass such price increases 
through to them, such contracts may be canceled by our customers and/or we may not be able to recoup the costs of 
such price increases. Additionally, if we are unable to continue to purchase our required quantities of raw materials on 
commercially reasonable terms, or at all, if we are unable to maintain or enter into purchasing contracts for commodities, 
or if delivery of materials from suppliers is delayed or non-conforming, our operations could be disrupted or our profitability 
could be adversely impacted. 

16 

  
 
Our international operations, in particular our emerging markets, are subject to various risks which could have 
a material adverse effect on our business, results of operations and financial condition.  

Our business is subject to certain risks associated with doing business internationally, particularly in emerging 

markets. Outside-North America net sales represented approximately 21% of our net sales for 2017. Most of our 
operations are in the U.S., but we also have manufacturing and customization facilities in India and Hungary with a 
services agreement with Opel Szentgotthard Automotive Manufacturing Ltd., formerly GM-PTH, and customization 
capability in Brazil, The Netherlands, China and Japan. Further, we intend to continue to pursue growth opportunities for 
our business in a variety of business environments outside the U.S., which could exacerbate the risks set forth below. Our 
international operations are subject to, without limitation, the following risks:  

• the burden of complying with multiple and possibly conflicting laws and any unexpected changes in regulatory 
requirements;  

• foreign currency exchange controls, import and export restrictions and tariffs, including restrictions promulgated 

by the Office of Foreign Assets Control of the U.S. Department of the Treasury, and other trade protection 
regulations and measures;  

• political risks, including increased trade protectionism and risks of loss due to civil disturbances, acts of terrorism, 
acts of war, guerilla activities and insurrection;  

• unstable economic, financial and market conditions and increased expenses as a result of inflation or higher 
interest rates;  

• difficulties in enforcement of third-party contractual obligations and intellectual property rights and collecting 
receivables through foreign legal systems;  
• difficulty in staffing and managing international operations and the application of foreign labor regulations;  
• differing local product preferences and product requirements;  

• fluctuations in currency exchange rates to the extent that our assets or liabilities are denominated in a currency 
other than the functional currency of the country where we operate;  

• potentially adverse tax consequences from changes in tax laws, requirements relating to withholding taxes on 
remittances and other payments by subsidiaries and restrictions on our ability to repatriate dividends from our 
subsidiaries; and  

• exposure to liabilities under anti-corruption and anti-money laundering laws, including the U.S. Foreign Corrupt 
Practices Act (“FCPA”) and similar laws and regulations in other jurisdictions.  

Any one of these factors could materially adversely affect our sales of products or services to international 

customers or harm our reputation, which could have a material adverse effect on our business, results of operations and 
financial condition.  

Our international operations require us to comply with anti-corruption laws and regulations of the U.S.      
government and various international jurisdictions.  

Doing business on a worldwide basis requires us and our subsidiaries to comply with the laws and regulations of the 

U.S. government and various international jurisdictions, and our failure to comply with these rules and regulations may 
expose us to liabilities. These laws and regulations may apply to companies, individual directors, officers, employees and 
agents, and may restrict our operations, trade practices investment decisions and partnering activities. In particular, our 
international operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the FCPA. The 
FCPA prohibits U.S. companies and their officers, directors, employees and agents acting on their behalf from corruptly 
offering, promising, authorizing or providing anything of value to foreign officials for the purposes of influencing official 
decisions or obtaining or retaining business or otherwise obtaining favorable treatment. The FCPA also requires 
companies to make and keep books, records and accounts that accurately and fairly reflect transactions and dispositions 
of assets and to maintain a system of adequate internal accounting controls. As part of our business, we deal with state-
owned business enterprises, the employees and representatives of which may be considered foreign officials for purposes 
of the FCPA. In addition, some of the international locations in which we operate lack a developed legal system and have 
elevated levels of corruption. As a result of the above activities, we are exposed to the risk of violating anti-corruption 
laws. Violations of these legal requirements are punishable by criminal fines and imprisonment, civil penalties, 
disgorgement of profits, injunctions, debarment from government contracts as well as other remedial measures. We have 
established policies and procedures designed to assist us and our personnel in complying with applicable U.S. and 
international laws and regulations. However, our employees, subcontractors and agents could take actions that violate 
these legal requirements, which could adversely affect our reputation, business, financial condition and results of 
operations.

Sales of our electric hybrid-propulsion systems have been, and are expected to continue to be, negatively 
impacted by external factors, including fuel price trends, regulatory requirements, alternative technologies 
and governmental entities electing not to subsidize the purchase of such products by end users.  

External factors, including diesel and natural gas fuel price trends, emissions and on-board diagnostics regulatory 
requirements, availability of compatible engine calibrations from engine manufacturers and alternative emerging green 
technologies, have negatively impacted, and are expected to continue to negatively impact, sales of our electric hybrid-
propulsion systems. In addition, the sales of our electric hybrid-propulsion systems for use in transit buses have been, and 
are expected to continue to be, negatively impacted by governmental entities electing not to subsidize the purchase of 
such products by end users. In 2017, we derived approximately 3% of our net sales from the sale of electric hybrid-
propulsion systems for use in transit buses to city, state and federal governmental end users. Such end users may be 
eligible to receive certain subsidies as a result of their purchase of vehicles using electric hybrid-propulsion systems. 
While we do not directly receive these subsidies, if any of the subsidizing entities elect to curtail such subsidies to end 
users for any reason including governmental budget reductions and related fiscal matters, failure of our electric hybrid 
technology to qualify for such subsidies or redundancy by alternative technologies created by our competitors, our sales 
from our electric hybrid-propulsion systems may be negatively impacted. For the year ended December 31, 2017, we 
experienced an increase in revenue generated from electric hybrid propulsion systems for use in transit buses of 16%. For 
the years ended December 31, 2016 and 2015, we experienced decreases in revenue generated from electric hybrid-
propulsion systems for use in transit buses of 16% and 22%, respectively. 

Any events that impact our brand name, including if the products we manufacture or distribute are found to be 
defective, could have an adverse effect on our reputation, cause us to incur significant costs and negatively 
impact our business, results of operations and financial condition.  

We face exposure to product liability claims in the event that the use of our products has, or is alleged to have, 
resulted in injury, death or other adverse effects. We currently maintain product liability insurance coverage, but we 
cannot be assured that we will be able to obtain such insurance on acceptable terms in the future, if at all, or that any 
such insurance will provide adequate coverage against potential claims. Product liability claims can be expensive to 
defend and can divert the attention of management and other personnel for long periods of time, regardless of the 
ultimate outcome. An unsuccessful product liability defense could have a material adverse effect on our business, results 
of operation, financial condition or prospects. If one of our products is determined to be defective, we may face substantial 
warranty costs and may be responsible for significant costs associated with a product recall or a redesign. We have had 
defect and warranty issues associated with certain of our products in the past, and we cannot give assurance similar 
product defects will not occur in the future. See NOTE 9 “Product Warranty Liabilities” of Notes to Consolidated Financial 
Statements included in Part II, Item 8 of this Annual Report on Form 10-K for additional details regarding these warranty 
issues.  

Furthermore, our business depends on the strong brand reputation we have developed. In addition to the risk of 
defective products, we also face significant risks in our efforts to penetrate new markets, where we have limited brand 
recognition. We also rely on our reputation with end users of our transmissions to specify our transmissions when 
purchasing new vehicles from our OEM customers. In the event we are not able to maintain or enhance our brand in 
these new markets or our reputation is damaged in our existing markets as a result of product defects or recalls, we may 
face difficulty in maintaining our pricing positions with respect to some of our products or experience reduced demand for 
our products, which could negatively impact our business, results of operations and financial condition. 

Additionally, we license the “Allison Transmission” name and certain related trademarks to third parties. If any third 

party uses the trade name “Allison Transmission” in ways that adversely affect such trade name or trademark, our 
reputation could suffer damage, which in turn could have a material adverse effect on our business, results of operations 
and financial condition. 

Our brand and reputation are dependent on the continued participation and level of service of our numerous 
independent distributors and dealers.  

We work with a network of approximately 1,400 independent distributors and dealers that provide post-sale service 

and parts and support equipment. Because we depend on the pull-through demand generated by end users for our 
products, any actions by the independent distributors or dealers, which are not in our control, may harm our reputation 
and damage the brand loyalty among our customer base. In the event that we are not able to maintain our brand 
reputation because of the actions of our independent distributors and dealers, we may face difficulty in maintaining our 
pricing positions with respect to some of our products or have reduced demand for our products, which could negatively 
impact our business, results of operations and financial condition. In addition, if a significant number of independent 
dealers were to terminate their contracts, it could adversely impact our business, results of operations and financial 
condition.  

18 

  
 
We are subject to cybersecurity risks to operational systems, security systems, or infrastructure owned by 
Allison or third-party vendors or suppliers.  

We are at risk for interruptions, outages, and breaches of: (i) operational systems, including business, financial, 

accounting, product development, data processing, or manufacturing processes, owned by us or our third-party vendors 
or suppliers; (ii) facility security systems, owned by us or our third-party vendors or suppliers; and/or (iii) transmission 
control modules or other in-product technology, owned by us or our third-party vendors or suppliers. Such cyber incidents 
could materially disrupt operational systems; result in loss of intellectual property, trade secrets or other proprietary or 
competitively sensitive information; compromise personally identifiable information of employees, customers, suppliers, or 
others; jeopardize the security of our facilities; and/or affect the performance of transmission control modules or other in-
product technology. A cyber incident could be caused by malicious third parties using sophisticated, targeted methods to 
circumvent firewalls, encryption, and other security defenses, including hacking, fraud, trickery, or other forms of 
deception. The techniques used by third parties change frequently and may be difficult to detect for long periods of time. A 
significant cyber incident could impact production capability, harm our reputation and/or subject us to regulatory actions or 
litigation, any of which could materially affect our business, results of operations and financial condition. 

Labor unrest could have a material adverse effect on our business, results of operations and financial 
condition.  

As of December 31, 2017, approximately 59% of our U.S. employees, representing over 50% of our total 

employees, were represented by the UAW and are subject to a collective bargaining agreement. In December 2017, we 
reached an agreement on a new six-year collective bargaining agreement with UAW Local 933, which is effective through 
November 2023. 

In addition to our unionized work force, many of our direct and indirect customers and vendors have unionized work 

forces. Strikes, work stoppages or slowdowns experienced by these customers or vendors or their other suppliers could 
result in slowdowns or closings of assembly plants that use our products or supply materials for use in the production of 
our products. Organizations responsible for shipping our products may also be impacted by strikes. Any interruption in the 
delivery of our products could reduce demand for our products and could have a material adverse effect on us.  

In general, we consider our labor relations with all of our employees to be good. However, in the future we may be 

subject to labor unrest. If strikes, work stoppages or lock-outs at our facilities or at the facilities of our vendors or 
customers occur or continue for a long period of time, our business, results of operations and financial condition may be 
materially adversely affected. 

In the event of a catastrophic loss of our key manufacturing facility, our business would be adversely affected.  

While we manufacture our products in several facilities and maintain insurance covering our facilities, including 
business interruption insurance, a catastrophic loss of the use of all or a portion of one of our manufacturing facilities due 
to accident, labor issues, weather conditions, acts of war, political unrest, terrorist activity, natural disaster or otherwise, 
whether short- or long-term, would have a material adverse effect on our business, results of operations and financial 
condition. Our most significant concentration of manufacturing is around our corporate headquarters in Indianapolis, 
Indiana, where we produce approximately 90% of our transmissions. In addition to our Indianapolis manufacturing 
facilities, we currently operate manufacturing facilities in both Szentgotthard, Hungary and Chennai, India. In the event of 
a disruption at the Indianapolis facilities, our other facilities may not be adequately equipped to operate at a level sufficient 
to compensate for the volume of production at the Indianapolis facility due to their size and the fact that they have not yet 
been tested for such significant increases in production volume. 

We could be materially adversely affected by any failure to maintain cost controls.  

We rely on our cost structure and operating discipline to achieve strong operating margins. There are many factors 
that could affect our ability to realize expected cost savings or achieve future cost savings that we are not able to control, 
including the need for unexpected significant capital expenditures; unexpected changes in commodity or component 
pricing, including an increase in export or import tariffs, that we are unable to pass on to our suppliers or customers and 
our inability to maintain efficiencies gained from our workforce optimization initiatives. Additionally, we have substantial 
indebtedness of approximately $2,576 million as of December 31, 2017. Our inability to maintain our cost controls could 
adversely impact our operating margins. 

19 

  
 
Many of the key patents and unpatented technology we use in our business are licensed to us, not owned by 
us, and our ability to use and enforce such patents and technology is restricted by the terms of the license.  

Protecting our intellectual property rights is critical to our ability to compete and succeed as a company. GM has 
granted us an irrevocable, perpetual, royalty-free, worldwide license under a large number of U.S. and foreign patents and 
patent applications, as well as certain unpatented technology and know-how, to design, develop, manufacture, use and 
sell fully-automatic transmissions and H 40/50 EP electric hybrid-propulsion transit bus systems for use in certain 
vocational vehicles, defense vehicles and off-road products. With respect to the bulk of the intellectual property licensed to 
us, our license is exclusive with respect to the design, development, manufacture, use and sale of fully-automatic 
transmissions and H 40/50 EP electric hybrid-propulsion transit bus systems in vocational vehicles above certain weight 
rating thresholds, certain defense vehicles and certain off-road products. It is non-exclusive with respect to certain other 
products that are within the scope of the licensed patents or to which the licensed technology can be applied. We consider 
the patents and technology licensed under such license agreement, as a whole, to be critical to preserving our competitive 
position in the market. However, GM continues to own such patents and technology, and GM has the right, in the first 
instance, to control the maintenance, enforcement and defense of such patents and the prosecution of the licensed patent 
applications. In addition, our ability to sublicense our rights is limited. 

We rely on unpatented technology, which exposes us to certain risks.  

We currently do, and may continue in the future to, rely on unpatented proprietary technology. In such regard, we 

cannot be assured that any of our applications for protection of our intellectual property rights will be approved or that 
others will not infringe or challenge our intellectual property rights. It is possible our competitors will independently develop 
the same or similar technology or otherwise obtain access to our unpatented technology.  

Although we believe the loss or expiration of any single patent would not have a material effect on our business, 

results of operations or financial position, there can be no assurance that any one, or more, of the patents licensed from 
GM, or any other intellectual property owned by or licensed to us, will not be challenged, invalidated or circumvented by 
third parties. In fact, a number of the patents licensed to us by GM are set to expire in the next few years. When a patent 
expires, the inventions it discloses can be used freely by others. Thus, the competitive advantage that we gain from the 
patents licensed to us from GM will decrease over time, and a greater burden will be placed on our own research and 
development and licensing efforts to develop and otherwise acquire technologies to keep pace with improvements of 
transmission-related technology in the marketplace. We enter into confidentiality and invention assignment agreements 
with employees, and into non-disclosure agreements with suppliers and appropriate customers so as to limit access to 
and disclosure of our proprietary information. We cannot be assured that these measures will provide meaningful 
protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, 
misappropriation or disclosure. If we are unable to maintain the proprietary nature of our technologies, our ability to 
sustain margins on some or all of our products may be affected, which could reduce our sales and profitability. Moreover, 
the protection provided for our intellectual property by the laws and courts of foreign nations may not be as advantageous 
to us as the protection available under U.S. law.  

Our pension and other post-retirement benefits funding obligations could increase significantly due to a 
reduction in funded status as a result of a variety of factors.  

Our earnings may be positively or negatively impacted by the amount of income or expense recorded for our defined 
benefit pension plans and other post-retirement benefits (“OPEB”). Accounting principles generally accepted in the United 
States of America (“GAAP”) require that income or expense for defined benefit pension plans be calculated at the annual 
measurement date using actuarial assumptions and calculations. These calculations reflect certain assumptions, the most 
significant of which relate to the capital markets, interest rates, health care inflation rates and other economic conditions. 
Changes in key economic indicators can change these assumptions. These assumptions, along with the actual value of 
assets at the measurement date, will impact the calculation of pension expense for the year. Although GAAP pension 
expense and pension contributions are not directly related, the key economic indicators that affect GAAP pension 
expense also affect the amount of cash that we would contribute to our defined benefit pension plans. Because the values 
of these defined benefit pension plans’ assets have fluctuated and will fluctuate in response to changing market 
conditions, the amount of gains or losses that will be recognized in subsequent periods, the impact on the funded status of 
the defined benefit pension plans and the future minimum required contributions, if any, could have a material adverse 
effect on our business, results of operations and financial condition. The magnitude of such impact cannot be determined 
with certainty at this time. However, the effect of a one percentage point decrease in the assumed discount rate would 
result in an increase in the December 31, 2017 defined benefit pension plans obligation of approximately $22 million. 
Likewise, a one percentage point decrease in the effective interest rate for determining defined benefit pension plans 
contributions would result in an increase in the minimum required contributions for 2018 of approximately $4 million. 
Similarly, a one percentage point decrease in the assumed discount rate would result in an increase in the December 31, 
2017 OPEB obligation of approximately $15 million. As of December 31, 2017, the funded status of our defined benefit 
pension plans was $7 million and the unfunded status of our OPEB plan was $102 million. 

20 

  
 
Environmental, health and safety laws and regulations may impose significant compliance costs and liabilities 
on us.  

We are subject to many environmental, health and safety laws and regulations governing emissions to air, 
discharges to water, the generation, handling and disposal of waste and the cleanup of contaminated properties. 
Compliance with these laws and regulations is costly. We have incurred and expect to continue to incur significant costs 
to maintain or achieve compliance with applicable environmental, health and safety laws and regulations. Moreover, if 
these environmental, health and safety laws and regulations become more stringent or expand to include a larger portion 
of our products or our customer’s products in the future, we could incur additional costs in order to ensure that our 
business and products comply with such regulations. In addition, we may not be successful in complying with, or the 
vehicle or customer OEMs to which we sell our products may choose not to comply with, such laws and regulations, which 
could impact our ability to sell our products in certain locations. Furthermore, if our products that are already placed in 
service are found to be non-compliant with certain laws, regulations and certifications, we may incur additional costs and 
fines. We cannot assure we are in full compliance with all environmental, health and safety laws and regulations. Our 
failure to comply with applicable environmental, health and safety laws and regulations and permit requirements could 
result in civil or criminal fines, penalties or enforcement actions, third-party claims for property damage and personal 
injury, requirements to clean up property or to pay for the costs of cleanup or regulatory or judicial orders enjoining or 
curtailing operations or requiring corrective measures, including the installation of pollution control equipment or remedial 
actions. Our failure to comply could also result in our failure to secure adequate insurance for our business, resulting in 
significant exposure, diminished ability to hedge our risks and material modifications of our business operations.  

We may be subject to liability as a potentially responsible party under the Comprehensive Environmental Response, 
Compensation and Liability Act and similar state or foreign laws for contaminated properties that we currently own, lease 
or operate or that we or our predecessors have previously owned, leased or operated, and sites to which we or our 
predecessors sent hazardous substances. Such liability may be joint and several so that we may be liable for more than 
our share of any contamination, and any such liability may be determined without regard to causation or knowledge of 
contamination. We or our predecessors have been named potentially responsible parties at contaminated sites from time 
to time.  

We manage the remediation of historical soil and groundwater contamination at our Indianapolis, Indiana facilities 

under an Agreed Order of Consent with the EPA. We recorded approximately $14 million for the estimated undiscounted 
environmental liabilities to be paid out over 30 years, which will be adjusted periodically as remediation efforts progress or 
as additional technical, regulatory or legal information becomes available. In the fourth quarter of 2016, we satisfied the 
financial assurance requirement under the AOC by securing a letter of credit in the amount of $15 million. See Part I, Item 
1, “Business — Environmental Compliance” and Part II, Item 8, NOTE 16, “Commitments and Contingencies” of this 
Annual Report on Form 10-K. There can be no assurances that future environmental remediation obligations will not have 
a material adverse effect on our results of operations and financial condition. In addition, we occasionally evaluate 
alternatives with respect to our facilities, including possible dispositions or closings. Investigations undertaken in 
connection with these activities may lead to discoveries of contamination that must be remediated, and closings of 
facilities may trigger remediation requirements that are not applicable to operating facilities. We may also face lawsuits 
brought by third parties that either allege property damage or personal injury as a result of, or seek reimbursement for 
costs associated with, such contamination. 

Our business and financial results may be adversely affected by government contracting risks.  

We are subject to various laws and regulations applicable to parties doing business with the U.S. government, 
including laws and regulations governing performance of U.S. government contracts, the use and treatment of U.S. 
government furnished property and the nature of materials used in our products. We may be unilaterally suspended or 
barred from conducting business with the U.S. government, or become subject to fines or other sanctions if we are found 
to have violated such laws or regulations. As a result of the need to comply with these laws and regulations, we are 
subject to increased risks of governmental investigations, civil fraud actions, criminal prosecutions, whistleblower law suits 
and other enforcement actions. The laws and regulations to which we are subject include, but are not limited to, Export 
Administration Regulations, the Federal Acquisition Regulation, International Traffic in Arms Regulations and regulations 
from the Bureau of Alcohol, Tobacco and Firearms and the FCPA.  

U.S. government contracts are subject to modification, curtailment or termination by the U.S. government without 

prior written notice, either for convenience or for default as a result of our failure to perform under the applicable contract. 
If terminated by the U.S. government as a result of our default, we could be liable for additional costs the U.S. government 
incurs in acquiring undelivered goods or services from another source and any other damages it suffers. Additionally, we 
cannot assign prime U.S. government contracts without the prior consent of the U.S. government contracting officer, and 
we are required to register with the Central Contractor Registration Database. Furthermore, the U.S. government 
periodically audits our governmental contract costs, which could result in fines, penalties or adjustment of costs and prices 
under the contracts. The result of, or expiration of the statute of limitations for, such audits could have an impact on 
reported net income and cash flow from operations. 

21 

  
 
Exchange rate fluctuations could adversely affect our results of operations and financial position.  

As a result of the expansion of our international operations, currency exchange rate fluctuations could affect our 
results of operations and financial position. We expect to generate an increasing portion of our net sales and expenses in 
such foreign currencies as the Japanese Yen, Euro, Indian Rupee, Brazilian Real, Chinese Yuan Renminbi, Canadian 
Dollar and Hungarian Forint. Although we may enter into foreign exchange agreements with financial institutions in order 
to reduce our exposure to fluctuations in the value of these and other foreign currencies, these transactions, if entered 
into, will not eliminate that risk entirely. To the extent that we are unable to match net sales received in foreign currencies 
with expenses paid in the same currency, exchange rate fluctuations could have a negative impact on our results of 
operations and financial condition. Additionally, because our consolidated financial results are reported in U.S. Dollars, if 
we generate net sales or earnings in other currencies, the conversion of such amounts into U.S. Dollars can result in an 
increase or decrease in the amount of our net sales or earnings. Furthermore, we sell certain of our products in our non-
North American markets denominated in the U.S. Dollar. To the extent that certain of the local currencies in our non-North 
American markets are relatively weaker than the U.S. Dollar, whether as a result of foreign governments’ influence or 
otherwise, we could become less price competitive, which could have a material adverse effect on the results of our 
operations. 

An impairment in the carrying value of goodwill, other intangible assets or long-lived assets could negatively 
affect our consolidated results of operations and net worth.  

Pursuant to GAAP, we are required to assess our goodwill and indefinite-lived intangible assets to determine if they 
are impaired on an annual basis, or more often if events or changes in circumstances indicate that impairment may have 
occurred. Intangible assets with finite lives are amortized over the useful life and are reviewed for impairment on triggering 
events such as events or changes in circumstances indicating that an impairment may have occurred. If the testing 
performed indicates that impairment has occurred, we are required to record a non-cash impairment charge for the 
difference between the carrying value of the goodwill and the implied fair value of the goodwill or the carrying value of the 
intangible assets and the fair value of the intangible assets in the period the determination is made. Disruptions to our 
business, end market conditions, protracted economic weakness and unexpected significant declines in operating results 
may result in charges for goodwill and other asset impairments.  

Our annual goodwill and trade name impairment tests for the year ended December 31, 2017 resulted in no 
impairment. Although our analysis regarding the fair value of goodwill and trade name indicated that they exceeded their 
respective carrying values, materially different assumptions regarding the future performance of our business could result 
in goodwill impairment losses. See NOTE 2 “Summary of Significant Accounting Policies” and NOTE 5 “Goodwill and 
Other Intangible Assets” of Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on 
Form 10-K for additional details. 

The carrying value of long-lived assets is evaluated whenever events or circumstances indicate that the carrying 
value of a long-lived asset may not be recoverable. Events or circumstances that would result in an impairment review 
primarily include a significant change in the use of an asset, a significant change in the projected future cash flows 
generated by an asset or the planned sale or disposal of an asset. The asset would be considered impaired when there is 
no future use planned for the asset or the future net undiscounted cash flows generated by the asset or asset group are 
less than its carrying value. An impairment loss would be recognized based on the amount by which the carrying value 
exceeds fair value and could have a material adverse effect on the results of our operations. 

As a result of events and circumstances in the fourth quarter of 2017, we reviewed certain of our long-lived assets 
related to the production of the TC10 product, resulting in a $32 million loss for the year ended December 31, 2017. See 
NOTE 2 “Summary of Significant Accounting Policies” and NOTE 4 “Property, Plant and Equipment” of Notes to 
Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K for additional details.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws and 
Delaware law might discourage, delay or prevent a change of control of our company or changes in our 
management and, as a result, depress the trading price of our common stock. 

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that 

could discourage, delay or prevent a change in control of our company or changes in our management that the 
stockholders of our company may deem advantageous. These provisions: 

•  authorize the issuance of blank check preferred stock that our Board of Directors could issue to increase the 

number of outstanding shares and to discourage a takeover attempt; 

•  limit the ability of stockholders to remove directors only “for cause”; 

•  prohibit our stockholders from calling a special meeting of stockholders; 

•  prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of 

our stockholders; 

•  provide that the Board of Directors is expressly authorized to adopt, or to alter or repeal our bylaws; 

•  establish advance notice requirements for nominations for election to our Board of Directors or for 

proposing matters that can be acted upon by stockholders at stockholder meetings; and 

•  require the approval of holders of at least two-thirds of the outstanding shares of common stock to amend the 

bylaws and certain provisions of the certificate of incorporation. 

These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of our 

company that our stockholders may believe to be in their best interests. These provisions could also discourage proxy 
contests and make it more difficult for our stockholders to elect directors of their choosing and cause us to take corporate 
actions other than those they desire.  

23 

  
 
Risks Related to Our Indebtedness 

Our substantial indebtedness could adversely affect our financial health, restrict our activities and affect our 
ability to meet our obligations.  

We have a significant amount of indebtedness. As of December 31, 2017, we had total indebtedness of $2,576 
million and we would have been able to borrow an additional $533 million, net of $17 million of outstanding letters of 
credit, under the revolving portion of Allison Transmission Inc.’s (“ATI”), the Company’s wholly-owned subsidiary, Senior 
Secured Credit Facility due 2021 (“Revolving Credit Facility”), less $17 million of letters of credit.  As of December 31, 
2017, we had no outstanding borrowings against the Revolving Credit Facility. At December 31, 2017, $1,176 million of 
our total indebtedness was associated with ATI’s, Senior Secured Credit Facility Term B-3 Loan due 2022 (“Term B-3 
Loan”, and together with the Revolving Credit Facility, the “Senior Secured Credit Facility”), $1,000 million of our total 
indebtedness was associated with ATI’s 5.0% Senior Notes due September 2024 (“5.0% Senior Notes”) and $400 million 
of our total indebtedness was associated with ATI’s 4.75% Senior Notes due October 2027 (“4.75% Senior Notes”). For a 
complete description of the terms of the Senior Secured Credit Facility, the 5.0% Senior Notes and the 4.75% Senior 
Notes, please see Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations – Liquidity and Capital Resources.” 

Our substantial indebtedness could have important consequences. For example, it could:  

•  make it more difficult for us to satisfy our obligations under our indebtedness;  

•  require us to further dedicate a substantial portion of our cash flow from operations to payments of principal and 

interest on our indebtedness, thereby reducing the availability of our cash flow to fund acquisitions, working 
capital, capital expenditures, research and development efforts and other general corporate purposes;  

•  increase our vulnerability to and limit our flexibility in planning for, or reacting to, downturns or changes in our 

business and the industry in which we operate;  

•  restrict us from making strategic acquisitions or cause us to make non-strategic divestitures;  

•  expose us to the risk of increased interest rates as borrowings under the Senior Secured Credit Facility are 

subject to variable rates of interest;  

•  place us at a competitive disadvantage compared to our competitors that have less debt; and  

•  limit our ability to borrow additional funds.  

In addition, the Revolving Credit Facility contains a maximum total senior secured leverage ratio. The Senior 
Secured Credit Facility, the indenture governing the 5.0% Senior Notes and the indenture governing the 4.75% Senior 
Notes also contain other negative and affirmative covenants that will limit our ability to engage in activities that may be in 
our long-term best interests. Our failure to comply with any of the covenants could result in an event of default which, if 
not cured or waived, could result in the acceleration of all of our indebtedness. 

Our ability to pay regular dividends on our common stock is subject to the discretion of our Board of Directors 
and may be limited by our structure and statutory restrictions and restrictions imposed by the Senior Secured 
Credit Facility, the indenture governing the 5.0% Senior Notes and the indenture governing the 4.75% Senior 
Notes as well as any future agreements. 

Our Board of Directors declared a quarterly dividend of $0.06 per share of common stock beginning in the second 

quarter of 2012, increased the quarterly dividend to $0.12 per share of common stock beginning in the second quarter of 
2013 and increased the quarterly dividend again to $0.15 per share of common stock beginning in the fourth quarter of 
2014.  However, the payment of future dividends will be at the discretion of our Board of Directors and will depend on, 
among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and 
contractual restrictions applying to the payment of dividends and other considerations that our Board of Directors deems 
relevant. The Senior Secured Credit Facility, the indenture governing the 5.0% Senior Notes and the indenture governing 
the 4.75% Senior Notes also effectively limit our ability to pay dividends. As a consequence of these limitations and 
restrictions, we may not be able to make, or may have to reduce or eliminate, the payment of dividends on our common 
stock. Accordingly, you may have to sell some or all of your common stock after price appreciation in order to generate 
cash flow from your investment. You may not receive a gain on your investment when you sell your common stock and 
you may lose the entire amount of the investment. Additionally, any change in the level of our dividends or the suspension 
of the payment thereof could adversely affect the market price of our common stock.

To service our indebtedness, we will require a significant amount of cash, and our ability to generate cash 
depends on many factors beyond our control.  

Our ability to make cash payments on our indebtedness and to fund planned capital expenditures will depend on our 
ability to generate significant operating cash flow in the future. This, to a significant extent, is subject to general economic, 
financial, competitive, legislative, regulatory and other factors that are beyond our control. 

We cannot ensure that our business will generate sufficient cash flow from operations or that future borrowings will 

be available to us under the Senior Secured Credit Facility in an amount sufficient to enable us to pay our indebtedness or 
to fund our other liquidity needs. In such circumstances, we may need to refinance all or a portion of our indebtedness on 
or before maturity. We cannot ensure that we will be able to refinance any of our indebtedness on commercially 
reasonable terms or at all. If we cannot service our indebtedness, we may have to take actions such as selling assets, 
seeking additional equity or reducing or delaying capital expenditures, strategic acquisitions, investments and alliances. 
We cannot ensure that any such actions, if necessary, could be effected on commercially reasonable terms or at all. 

If we fail to pay principal, premium, if any, and interest on our indebtedness or to otherwise comply with the 
covenants in the instruments governing our indebtedness, we may be forced into bankruptcy or liquidation by 
our lenders. 

If we are unable to generate sufficient cash flow or are otherwise unable to obtain funds necessary to meet required 
payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various 
covenants in the instruments governing our indebtedness, we could be in default under the terms of the agreements 
governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the 
funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under the 
Senior Secured Credit Facility could elect to terminate their commitments thereunder, cease making further loans and 
institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation. If our operating 
performance declines, we may in the future need to obtain waivers from the required lenders under the Senior Secured 
Credit Facility to avoid being in default. If we or any of our subsidiaries breach the covenants under the Senior Secured 
Credit Facility and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we 
would be in default under the Senior Secured Credit Facility, the lenders could exercise their rights, as described above, 
and we could be forced into bankruptcy or liquidation. 

Despite current indebtedness levels, we and our subsidiaries may still be able to incur additional 
indebtedness, which could further exacerbate the risks associated with our substantial financial leverage.  

We and our subsidiaries may be able to incur additional indebtedness in the future because the terms of our 

indebtedness do not fully prohibit us or our subsidiaries from doing so. Subject to covenant compliance and certain 
conditions, our indebtedness permits additional borrowing, including total borrowing up to $533 million under the 
Revolving Credit Facility. If new debt is added to our current debt levels and our subsidiaries’ current debt levels, the 
related risks that we and they now face could intensify.

ITEM 3. Legal Proceedings 

We are subject to various contingencies, including routine legal proceedings and claims arising out of the normal 
course of business. These proceedings primarily involve commercial claims, product liability claims, personal injury claims 
and workers’ compensation claims. The outcome of these lawsuits, legal proceedings and claims cannot be predicted with 
certainty. Nevertheless, we believe the outcome of any of these currently existing proceedings, even if determined 
adversely, would not have a material adverse effect on our financial condition or results of operations. See also NOTE 16,

As of February 2, 2018, there were approximately 46,950 stockholders of record of our common stock, which 
includes the actual number of holders registered on the books of the Company and holders of shares in “street name” or 
persons, partnerships, associations, corporations or other entities identified in security position listings maintained by 
depositories.  

Dividends 

Our Board of Directors declared a quarterly dividend of $0.15 per share each quarter during 2017 and 2016. We 
expect to continue paying cash dividends on a quarterly basis; however, future dividends are subject to approval of the 
Board of Directors and may be adjusted as business needs or market conditions change. In addition, our Senior Secured 
Credit Facility, the indenture governing the 5.0% Senior Notes and the indenture governing the 4.75% Senior Notes 
restrict the payment of dividends under certain circumstances.  

Unregistered Sales of Equity Securities  

During the period covered by this Annual Report on Form 10-K, we did not offer or sell any equity securities that 

were not registered under the Securities Act of 1933, as amended (the “Securities Act”).

Issuer Purchases of Equity Securities  

On November 14, 2016, our Board of Directors authorized us to repurchase up to $1,000 million of our common 

stock pursuant to a stock repurchase program (“2016 Repurchase Program”). On November 8, 2017, our Board of 
Directors increased the authorization by $500 million, bringing the total amount authorized under the 2016 Repurchase 
Program to $1,500 million. The terms of the 2016 Repurchase Program provide that we may repurchase shares of our 
common stock, from time to time depending on market conditions and corporate needs, in the open market or through 
privately negotiated transactions in accordance with Rule 10b-18 of the Exchange Act.  Unless earlier terminated by our 
Board of Directors, the 2016 Repurchase Program will expire on December 31, 2019.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion contains forward-looking statements regarding industry trends, our expectations regarding 

our future performance, liquidity and capital resources and other non-historical statements that involve risks and 
uncertainties. Our actual results may differ materially from those discussed in or implied by the forward looking statements 
as a result of various factors, including, without limitation, those set forth under Part I, Item 1A, “Risk Factors,” and other 
matters included elsewhere in this Annual Report on Form 10-K. The following discussion and analysis of our financial 
condition and results of operations should be read in conjunction with our consolidated financial statements and the notes 
thereto included elsewhere in this Annual Report on Form 10-K, as well as the information presented under Part II, Item 6 
of this Annual Report on Form 10-K.  

Overview  

We design and manufacture commercial and defense fully-automatic transmissions. The business was founded in 

1915 and has been headquartered in Indianapolis, Indiana since inception. Allison was an operating unit of General 
Motors Corporation from 1929 until 2007, when Allison once again became a stand-alone company. In March 2012, 
Allison began trading on the New York Stock Exchange under the symbol, “ALSN”.  

We have approximately 2,700 employees and 13 different transmission product lines. Although approximately 79% 
of revenues were generated in North America in 2017, we have a global presence by serving customers in Europe, Asia, 
South America and Africa. We serve customers through an independent network of approximately 1,400 independent 
distributor and dealer locations worldwide. 

Trends Impacting Our Business   

Our net sales are driven by commercial vehicle production, which tends to be highly correlated to macroeconomic 

conditions. During 2018, we expect continued strength in our North American On-Highway end market. We expect 
demand in the Defense, Outside North America On-Highway and North America Off-Highway end markets to increase, 
and we expect that demand in the Service Parts, Support Equipment and Other end market will decrease.

North America On-Highway end market net sales were up 15% for the year ended December 31, 2017 compared to 

the year ended December 31, 2016, principally driven by higher demand for Rugged Duty Series models. 

North America Electric Hybrid-Propulsion Systems for Transit Bus end market net sales were up 16% for the year 
ended December 31, 2017 compared to the year ended December 31, 2016, principally driven by the timing of certain 
transit property orders. 

North America Off-Highway end market net sales were up 629% for the year ended December 31, 2017 compared 

to the year ended December 31, 2016, principally driven by higher demand from hydraulic fracturing applications. 

Defense end market net sales were up 2% for the year ended December 31, 2017 compared to the year ended 

December 31, 2016, principally driven by higher demand.  

Outside North America On-Highway end market net sales were up 13% for the year ended December 31, 2017 
compared to the year ended December 31, 2016, principally driven by higher demand in Asia, Europe and South America. 

Outside North America Off-Highway end market net sales were up 242% for the year ended December 31, 2017 
compared to the year ended December 31, 2016, principally driven by improved demand in the mining and energy sector.

Service Parts, Support Equipment and Other end market net sales were up 41% for the year ended December 31, 

2017 compared to the year ended December 31, 2016, principally driven by higher demand for North America service 
parts and global support equipment.  

Key Components of our Results of Operations  

Net sales  

We generate our net sales primarily from the sale of transmissions, transmission parts, support equipment, defense 

kits, engineering services, royalties and extended transmission coverage to a wide array of OEMs, distributors and the 
U.S. government. Sales are recorded net of provisions for customer allowances and other rebates. Engineering services 
are recorded as net sales in accordance with the terms of the contract. The associated costs are recorded in cost of sales. 
We also have royalty agreements with third parties that provide net sales as a result of joint efforts in developing 
marketable products.  

Cost of sales  

Our primary components of cost of sales are purchased parts, the overhead expense related to our manufacturing 

operations and direct labor associated with the manufacture and assembly of transmissions and parts. For the year ended 
December 31, 2017, direct material costs were approximately 69%, overhead costs were approximately 25% and direct 
labor costs were approximately 6% of total cost of sales. We are subject to changes in our cost of sales caused by 
movements in underlying commodity prices. We seek to hedge against this risk by using commodity swap contracts and 
LTSAs. See Part II, Item 7A, “Quantitative and Qualitative Disclosures about Market Risk—Commodity Price Risk” 
included in this Annual Report on Form 10-K.  

Selling, general and administrative  

The principal components of our selling, general and administrative expenses are salaries and benefits for our office 

personnel, advertising and promotional expenses, product warranty expense, expenses relating to certain information 
technology systems and amortization of our intangibles.

We incur costs in connection with research and development programs that are expected to contribute to future 

earnings. Such costs are expensed as incurred.

Non-GAAP Financial Measures 

We use Adjusted Earnings before Interest, Taxes, Depreciation, and Amortization (“EBITDA”) and Adjusted EBITDA 

margin to measure our operating profitability. We believe that Adjusted EBITDA and Adjusted EBITDA margin provide 
management, investors and creditors with useful measures of the operational results of our business and increase the 
period-to-period comparability of our operating profitability and comparability with other companies. Adjusted EBITDA 
margin is also used in the calculation of management’s incentive compensation program. The most directly comparable 
GAAP measure to Adjusted EBITDA is Net income. Adjusted EBITDA is calculated as the earnings before interest 
expense, income tax expense, amortization of intangible assets, depreciation of property, plant and equipment and other 
adjustments as defined by our Senior Secured Credit Facility. Adjusted EBITDA margin is calculated as Adjusted EBITDA 
divided by net sales. 

We use Adjusted free cash flow to evaluate the amount of cash generated by our business that, after the capital 
investment needed to maintain and grow our business and certain mandatory debt service requirements, can be used for 
repayment of debt, stockholder distributions and strategic opportunities, including investing in our business and 
strengthening our balance sheet. We believe that Adjusted free cash flow enhances the understanding of the cash flows 
of our business for management, investors and creditors. Adjusted free cash flow is also used in the calculation of 
management’s incentive compensation program. The most directly comparable GAAP measure to Adjusted free cash flow 
is Net cash provided by operating activities.

Net sales 

Net sales for the year ended December 31, 2017 were $2,262 million compared to $1,840 million for the year ended 

December 31, 2016, an increase of 23%. The increase was principally driven by a $154 million, or 41%, increase in net 
sales in the Service Parts, Support Equipment and Other end market principally driven by higher demand for North 
America service parts and global support equipment, a $144 million, or 15%, increase in net sales in the North America 
On-Highway end market principally driven by higher demand for Rugged Duty Series models, a $44 million increase in net 
sales in the North America Off-Highway end market principally driven by higher demand from hydraulic fracturing 
applications, a $39 million, or 13%, increase in net sales in the Outside North America On-Highway end market principally 
driven by higher demand in Asia, Europe and South America, a $29 million increase in net sales in the Outside North 
America Off-Highway end market principally driven by improved demand in the mining and energy sectors, a $10 million, 
or 16%, increase in net sales in the North America Electric Hybrid-Propulsion Systems for Transit Bus end market 
principally driven by the timing of certain transit property orders and a $2 million, or 2%, increase in net sales in the 
Defense end market principally driven by higher demand. See “Trends Impacting Our Business” above for additional 
information on net sales by end market. 

Cost of sales 

Cost of sales for the year ended December 31, 2017 were $1,131 million compared to $976 million for the year 
ended December 31, 2016, an increase of 16%. The increase was principally driven by increased material cost and 
manufacturing expenses commensurate with increased net sales, $9 million associated with the ratification of a new 
collective bargaining agreement with UAW Local 933 and $6 million of higher incentive compensation expense.

Gross profit 

Gross profit for the year ended December 31, 2017 was $1,131 million compared to $864 million for the year ended 

December 31, 2016, an increase of 31%. The increase was principally driven by $260 million related to increased net 
sales and $38 million of price increases on certain products, partially offset by $9 million of expenses associated with the 
ratification of a new collective bargaining agreement with UAW Local 933, $9 million of higher manufacturing expense 
commensurate with increased net sales, $6 million of higher incentive compensation expense and $7 million of 
unfavorable material cost. Gross profit as a percent of net sales for the year ended December 31, 2017 increased 3% 
compared to the same period in 2016 principally driven by favorable sales volume and price increases on certain 
products, partially offset by expense associated with the ratification of a new collective bargaining agreement, higher 
incentive compensation expense and unfavorable material cost. 

Selling, general and administrative  

Selling, general and administrative expenses for the year ended December 31, 2017 were $342 million compared to 
$324 million for the year ended December 31, 2016, an increase of 6%. The increase was principally driven by increased 
commercial activities spending, $6 million of higher incentive compensation expense, $5 million of unfavorable product 
warranty adjustments and $2 million of higher stock-based compensation expense, partially offset by $4 million of 
stockholder activism expenses in 2016 that did not recur in 2017 and $4 million of favorable DPIM adjustments. 

Engineering — research and development  

Engineering expenses for the year ended December 31, 2017 were $105 million compared to $88 million for the 

year ended December 31, 2016, an increase of 19%. The increase was principally driven by increased product initiatives 
spending and $3 million of higher incentive compensation expense. 

Loss associated with impairment of long-lived assets 

During the fourth quarter of 2017, we recorded approximately $32 million of losses associated with impairment of 

certain of our long-lived assets related to the production of the TC10 transmission. See NOTE 4 “Property, Plant and 
Equipment” of Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K 
for additional details. 

Interest expense, net 

Interest expense, net for the year ended December 31, 2017 was $103 million compared to $101 million for the year 

ended December 31, 2016, an increase of 2%. The increase was principally driven by $36 million of higher interest 
expense on ATI’s 5.0% Senior Notes issued in September 2016, $8 million of higher interest expense for our interest rate 
derivatives that became effective in August 2016, $5 million of interest expense on ATI’s 4.75% Senior Notes issued in 
September 2017 and $4 million of interest expense on revolving loan balances in 2017, partially offset by $35 million 
lower interest expense on ATI’s Term B-3 Loan principally due to repayment of $1,200 million of principal in the third 
quarter of 2016 and $16 million of favorable mark-to-market adjustments for our interest rate derivatives. 

Expenses related to long-term debt refinancing 

In September 2016, we refinanced our Senior Secured Credit Facility, resulting in expenses of $12 million for the 

year ended December 31, 2016. 

Other (expense) income, net 

Other expense, net for the year ended December 31, 2017 was $22 million compared to other income, net of $2 
million for the year ended December 31, 2016. The change was principally driven by a $15 million increase in technology-
related investments expense, $5 million of unfavorable vendor settlements in 2017 and $4 million of higher foreign 
exchange losses on intercompany financing. 

Income tax expense 

Income tax expense for the year ended December 31, 2017 was $23 million compared to $126 million for the year 

ended December 31, 2016, resulting in an effective tax rate of 4% and 37% for years ended December 31, 2017 and 
December 31, 2016, respectively. The decrease was a result of the U.S. Tax Cuts and Jobs Act enacted into law in 2017 
and was principally driven by a $157 million decrease in net deferred tax liabilities to reflect the decrease in the corporate 
income tax rate from 35% to 21%, partially offset by a $5 million increase in tax liabilities related to the deemed 
repatriation of accumulated foreign earnings and profits.

Net sales 

Net sales for the year ended December 31, 2016 were $1,840 million compared to $1,986 million for the year ended 
December 31, 2015, a decrease of 7%. The decrease was principally driven by a $97 million, or 9%, decrease in net sales 
in the North America On-Highway end market driven by lower demand from Rugged Duty Series and Highway Series 
models partially offset by higher demand for Pupil Transport/Shuttle models, a $48 million, or 87%, decrease in net sales 
in the North American Off-Highway end market driven by the previously contemplated impact of low energy prices, a $23 
million, or 66%, decrease in net sales in the Outside North America Off-Highway end market driven by lower demand in 
the mining and energy sectors, a $12 million, or 16%, decrease in net sales in the North America Hybrid-Propulsion 
Systems for Transit Bus end market driven by lower demand due to engine emissions improvements and other alternative 
technologies, and an $11 million, or 3%, decrease in net sales in the Service Parts, Support Equipment and Other end 
market driven by lower demand for North America Off-Highway service parts, partially offset by a $43 million, or 16%, 
increase in net sales in the Outside North America On-Highway end market driven by higher demand in Europe and 
Japan partially offset by lower demand in China and a $2 million, or 2%, increase in net sales in the Defense end market 
principally driven by higher demand for Wheeled Defense partially offset by lower demand for Tracked Defense. 

Cost of sales 

Cost of sales for the year ended December 31, 2016 were $976 million compared to $1,052 million for the year 
ended December 31, 2015, a decrease of 7%. The decrease was principally driven by $51 million of decreased direct 
material costs and $22 million of lower manufacturing expense, in each case consistent with historical trends and 
management’s expectations given the respective change in sales volume, and $10 million of favorable direct material 
costs, partially offset by $7 million of higher incentive compensation expense. 

Gross profit 

Gross profit for the year ended December 31, 2016 was $864 million compared to $934 million for the year ended 

December 31, 2015, a decrease of 7%. The decrease was principally driven by $98 million related to decreased net sales 
and $7 million of higher incentive compensation expense, partially offset by $22 million of lower manufacturing expense 
commensurate with decreased net sales, $10 million of favorable direct material costs and $3 million resulting from price 
increases on certain products. Gross profit as a percent of net sales was flat for the year compared to 2015 principally 
driven by favorable direct material costs and price increases on certain products, offset by unfavorable sales volume and 
higher incentive compensation expense.

Selling, general and administrative  

Selling, general and administrative for the year ended December 31, 2016 were $324 million compared to $317 

million for the year ended December 31, 2015, an increase of 2%. The increase was principally driven by $15 million of 
higher incentive compensation expense, $4 million of stockholder activism expenses and $3 million of unfavorable 
adjustments related to the DPIM extended coverage program, partially offset by $5 million of lower product warranty 
expense, $5 million of lower intangible asset amortization, $2 million of unfavorable 2015 product warranty adjustments 
and reduced global commercial spending activities.  

Engineering — research and development  

Engineering expenses for the year ended December 31, 2016 were $88 million compared to $93 million for the year 

ended December 31, 2015, a decrease of 4%. The decrease was principally driven by the cadence of certain product 
initiatives, partially offset by $3 million of higher incentive compensation expense. 

Trade name impairment 

During the fourth quarter of 2015, we recorded a trade name impairment charge of $80 million as a result of lower 
forecasted net sales for certain of our end markets. Refer to NOTE 5, “Goodwill and Other Intangible Assets” in Part II, 
Item 8, of this Annual Report on Form 10-K. No trade name impairment charges were recorded in 2016. 

Environmental remediation 

During the third quarter of 2015, we recorded approximately $14 million for environmental remediation expenses as 
a result of the EPA determining that GM’s environmental remediation activities at our Indianapolis, Indiana manufacturing 
facilities were complete, and our assumption of responsibility for future operating, monitoring and maintenance activities. 
Refer to NOTE 16 “Commitments and Contingencies” in Part II, Item 8, of this Annual Report on Form 10-K.  

Loss associated with impairment of long-lived assets 

During the first quarter of 2015, we recorded approximately $1 million of losses associated with impairment of 

certain of our long-lived assets related to the production of the H3000 and H4000 hybrid-propulsion systems.  

Interest expense, net 

Interest expense, net for the year ended December 31, 2016 was $101 million compared to $114 million for the year 

ended December 31, 2015, a decrease of 12%. The decrease was principally driven by $14 million of favorable mark-to-
market adjustments for our interest rate derivatives, $9 million of lower interest expense as a result of the repurchase and 
redemption of ATI’s 7.125% Senior Notes in the second quarter of 2015, $8 million of lower interest expense on ATI’s 
Term B-3 Loan due primarily to the repayment of $1,200 million of principal in the third quarter of 2016, and $1 million of 
lower amortization of deferred financing fees, partially offset by $14 million of interest expense on ATI’s 5.0% Senior 
Notes issued in September 2016 and $7 million of interest expense for our interest rate derivatives that became effective 
in August 2016. 

Expenses related to long-term debt refinancing 

In September 2016, we refinanced our Senior Secured Credit Facility, resulting in expenses of $12 million for the 

year ended December 31, 2016. In April 2015, we completed a cash tender offer to purchase any and all of the 
outstanding 7.125% Senior Notes. The tender offer resulted in the repurchase of $421 million of the 7.125% Senior Notes 
in April 2015. In May 2015, we redeemed the remaining $50 million of the outstanding 7.125% Senior Notes, resulting in 
premiums and expenses totaling $26 million for the year ended December 31, 2015.  

Other income (expense), net 

Other income (expense), net for the year ended December 31, 2016 was income of $2 million compared to zero for 
the year ended December 31, 2015. The change was principally driven by $3 million of net gains on derivative contracts 
and $1 million of lower foreign exchange losses on intercompany financing, partially offset by $1 million of technology-
related investment expense and $1 million of miscellaneous expense, net. 

Income tax expense 

Income tax expense for the year ended December 31, 2016 was $126 million compared to $107 million for the year 
ended December 31, 2015, resulting in an effective tax rate of 37% for each of the years ended December 31, 2016 and 
2015.

Liquidity and Capital Resources  

We generate cash primarily from operations to fund our operating, investing and financing activities. Our principal 

uses of cash are operating expenses, capital expenditures, debt service, stock repurchases, dividends on common stock 
and working capital needs. We had total available cash and cash equivalents of $199 million and $205 million as of 
December 31, 2017 and 2016, respectively. Of the available cash and cash equivalents, approximately $149 million and 
$124 million were deposited in operating accounts while approximately $50 million and $81 million were invested in U.S. 
government backed securities as of December 31, 2017 and 2016, respectively.  

As of December 31, 2017, the total of cash and cash equivalents held by foreign subsidiaries was $75 million, the 
majority of which was located in Europe and China. The geographic location of our cash aligns with our business growth 
strategy. We manage our worldwide cash requirements considering available funds among the subsidiaries through which 
we conduct our business and the cost effectiveness with which those funds can be accessed. As a result, we do not 
anticipate that local liquidity restrictions will preclude us from funding our targeted expectations or operating needs with 
local resources. 

As of December 31, 2017, the Company had approximately $62 million of undistributed earnings in foreign 

subsidiaries which were subject to the one-time repatriation tax on foreign earnings required by the Tax Cuts and Jobs Act 
(“Tax Act”). As a result, we recorded a charge of $5 million for the one-time repatriation tax, to be paid to the U.S. 
Government over the next eight years. We have not recognized any deferred tax liabilities associated with earnings in 
foreign subsidiaries, except for our subsidiaries located in China and Hong Kong, as they are intended to be permanently 
reinvested and used to support foreign operations. We have recorded a deferred tax liability of $2 million for the tax 
liability associated with the remittance of previously taxed income and unremitted earnings for our subsidiaries located in 
China and Hong Kong. 

Our liquidity requirements are significant, primarily due to our debt service requirements. As of December 31, 2017, 

we had $1,176 million of indebtedness associated with ATI’s Term B-3 Loan, $1,000 million of indebtedness associated 
with ATI’s 5.0% Senior Notes and $400 million of indebtedness associated with ATI’s 4.75% Senior Notes. The minimum 
required quarterly principal payment on ATI’s Term B-3 Loan through its maturity date of September 2022 is $3 million. 
There are no required quarterly principal payments on ATI’s 5.0% Senior Notes and 4.75% Senior Notes. 

Our ability to make payments on and to refinance our indebtedness and to fund planned capital expenditures will 
depend on our ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, 
regulatory and other factors that may be beyond our control. We made net principal payments of $427 million, $215 
million and $117 million on our Senior Secured Credit Facility during the years ended December 31, 2017, 2016 and 
2015, respectively. 

The Senior Secured Credit Facility provides for a $550 million Revolving Credit Facility, net of an allowance for up to 

$75 million in outstanding letters of credit commitments. Throughout the year ended December 31, 2017, we made 
periodic withdrawals and payments on the Revolving Credit Facility as part of our debt management plans. The maximum 
amount outstanding at any time during the year ended December 31, 2017 on the Revolving Credit Facility was $300 
million. The Revolving Credit Facility was not utilized during the years ended December 31, 2016 and 2015. As of 
December 31, 2017, we had $533 million available under the Revolving Credit Facility, net of $17 million in letters of 
credit. As of December 31, 2017, we had no revolving loans outstanding. If we have revolving loan commitments 
outstanding on the Revolving Credit Facility at the end of a fiscal quarter, the Senior Secured Credit Facility requires us to 
maintain a specified maximum total senior secured leverage ratio of 5.50x. Additionally, within the terms of the Senior 
Secured Credit Facility, a senior secured leverage ratio at or below 4.00x results in the elimination of excess cash flow 
payments on the Senior Secured Credit Facility for the applicable year. As of December 31, 2017, the senior secured 
leverage ratio was 1.13x. The Senior Secured Credit Facility also provides certain financial incentives based on our total 
leverage ratio. A total leverage ratio at or below 4.00x results in a 25 basis point reduction to the applicable margin on our 
Revolving Credit Facility, and a total leverage ratio at or below 3.50x results in a 12.5 basis point reduction to the 
Revolving Credit Facility commitment fee and an additional 25 basis point reduction to the applicable margin on our 
Revolving Credit Facility. These reductions would remain in effect as long as we achieve a total leverage ratio at or below 
the related threshold. As of December 31, 2017, our total leverage ratio was 2.74x. 

In addition, the Senior Secured Credit Facility includes, among other things, customary restrictions (subject to 
certain exceptions) on our ability to incur certain indebtedness, grant certain liens, make certain investments, declare or 
pay certain dividends, or repurchase shares of our common stock. The indentures governing the 5.0% Senior Notes and 
4.75% Senior Notes contain negative covenants restricting or limiting our ability to, among other things, incur or guarantee 
additional indebtedness, incur liens, pay dividends on, redeem or repurchase our capital stock, make certain investments, 
permit payment or dividend restrictions on certain of our subsidiaries, sell assets, engage in certain transactions with 
affiliates, and consolidate or merge or sell all or substantially all of our assets. As of December 31, 2017, we are in 
compliance with all covenants under the Senior Secured Credit Facility and indentures governing the 5.0% Senior Notes 
and 4.75% Senior Notes. 

39 

  
 
Our credit ratings are reviewed by Moody’s Investors Service (“Moody’s”) and Fitch Ratings (“Fitch”). In September 

2017, our credit ratings were reviewed by Moody’s and Fitch. Moody’s held our corporate rating at ‘Ba2’ and our 5.0% 
Senior Notes rating at ‘Ba3’, upgraded our Term B-3 Loan rating to ‘Baa3’, and assigned ‘Ba3’ to the 4.75% Senior Notes. 
Fitch held our corporate rating at ‘BB’, our Term B-3 Loan rating at ‘BB+’, and our 5.0% Senior Notes rating at ‘BB’ and 
assigned ‘BB’ to the 4.75% Senior Notes. 

On November 14, 2016, our Board of Directors authorized us to repurchase up to $1,000 million of our common 

stock pursuant to the 2016 Repurchase Program. On November 8, 2017, our Board of Directors increased the 
authorization by $500 million, bringing the total amount authorized under the 2016 Repurchase Program to $1,500 million. 
During 2017, we repurchased approximately $885 million of our common stock under the 2016 Repurchase Program. All 
of the repurchase transactions during 2017 were settled in cash during the same period. As of December 31, 2017, we 
had approximately $554 million available under the 2016 Repurchase Program. 

The following table shows our sources and uses of funds for the years ended December 31, 2017, 2016 and 2015

Generally, cash provided by operating activities has been adequate to fund our operations. Due to fluctuations in our 

cash flows and the growth in our operations, it may be necessary from time to time in the future to borrow under the 
Senior Secured Credit Facility to meet cash demands. We anticipate cash provided by operating activities, cash and cash 
equivalents and borrowing capacity under the Senior Secured Credit Facility will be sufficient to meet our cash 
requirements for the next twelve months. 

Cash provided by operating activities  

Operating activities for the year ended December 31, 2017 generated $658 million of cash compared to $591 million 

for the year ended December 31, 2016. The increase was principally driven by increased gross profit, higher sales 
allowances and higher deferred revenue, partially offset by increased cash income taxes, higher inventories, increased 
cash interest expense, increased pension funding payments and increased incentive compensation payments. 

Operating activities for the year ended December 31, 2016 generated $591 million of cash compared to $580 million 

for the year ended December 31, 2015. The increase was principally driven by higher accounts payable, lower 
inventories, lower incentive compensation payments, decreased excess tax benefit from stock-based compensation, 
lower interest paid as a result of debt repayments and refinancing, lower manufacturing expense, favorable direct material 
costs and higher other liabilities, net, partially offset by decreased net sales and higher accounts receivable. 

Cash used for investing activities  

Investing activities for the year ended December 31, 2017 used $94 million of cash compared to $72 million for the 
year ended December 31, 2016. The increase was principally driven by an increase of $20 million in capital expenditures 
and an increase of $2 million in technology-related initiatives. The increase in capital expenditures was principally driven 
by spending related to investments in productivity and replacement programs and higher product initiatives spending. 

Investing activities for the year ended December 31, 2016 used $72 million of cash compared to $60 million for the 

year ended December 31, 2015. The increase was principally driven by an increase of $13 million in capital expenditures.  
The increase in capital expenditures was principally driven by spending related to investments in productivity and

Cash used for financing activities  

Financing activities for the year ended December 31, 2017 used $574 million of cash compared to $564 million for 

the year ended December 31, 2016. The increase was principally driven by $629 million of increased repurchases of 
common stock, $6 million of 2016 excess tax benefit from stock-based compensation and $5 million of decreased 
proceeds from common stock issuance in connection with stock option exercises, partially offset by $603 million of 
increased net debt borrowings, $15 million of lower debt financing fees and $11 million of decreased dividend payments. 

Financing activities for the year ended December 31, 2016 used $564 million of cash compared to $529 million for 

the year ended December 31, 2015. The increase was principally driven by $78 million of increased payments, net on 
long-term debt, $12 million of increased debt financing fees associated with the issuance of the 5.0% Senior Notes and 
the amendments to the Senior Secured Credit Facility in the third quarter of 2016, and $2 million of decreased excess tax 
benefit from stock-based compensation, partially offset by $50 million of lower stock repurchases, $5 million of decreased 
dividend payments, and $1 million of increased proceeds from the exercise of stock options.

(1)  Senior Secured Credit Facility includes principal payments and estimated interest payments. Interest on the Term B-3 
Loan is equal to the London Interbank Offered Rate (“LIBOR”) plus 2.00%. For the purposes of this table the rate has 
been calculated using LIBOR as of December 31, 2017, resulting in an applied rate of 3.57%. Actual payments will 
vary. 

(2)  5.0% Senior Notes include principal and interest payments based on a fixed interest rate of 5.00%. 

(3)  4.75% Senior Notes include principal and interest payments based on a fixed interest rate of 4.75%. 

(4)  Estimated pension funding and post-retirement benefit payments are based on an increasing discount rate and 
effective interest rate for funding purposes between 3.8% - 4.6%. Pension funding and post-retirement benefit 
payments are excluded from the table beyond year 5, though we expect funding and payments to continue beyond 
year 5. See NOTE 13 “Employee Benefit Plans” of Notes to Consolidated Financial Statements included in Part II, 
Item 8, of this Annual Report on Form 10-K for the funding status of our pension plans and other post-retirement 
benefit plan as of December 31, 2017.  

(5)  Defense price reduction reserve, estimated warranty obligations and sales allowance programs, which total $56 

million, $55 million and $34 million, respectively, as of December 31, 2017 have been excluded from this table as 
timing of any payments are uncertain.

Critical Accounting Policies and Significant Accounting Estimates 

The preparation of the consolidated financial statements in accordance with GAAP requires management to make 

estimates and assumptions that affect the reported amounts of some assets and liabilities and, in some instances, the 
reported amounts of net sales and expenses during the applicable reporting period. Differences between actual amounts 
and estimates are recorded in the period identified. Estimates can require a significant amount of judgment, and a 
different set of judgments could result in changes to our reported results. A summary of our critical accounting estimates 
is included below. 

Revenue Recognition  

Revenue recognition contains uncertainties because it requires management to make assumptions and to apply 

judgment to estimate the amount of sales incentives and provision for government price reductions. Distributor and 
customer sales incentives, consisting of allowances and other rebates, are estimated at the time of sale based upon 
history and experience and are recorded as a reduction to net sales. Incentive programs are generally product specific or 
region specific. Some factors used in estimating the cost of incentives include the number of transmissions that will be 
affected by the incentive program and the rate of acceptance of any incentive program. If the actual number of affected 
transmissions differs from this estimate, or if a different mix of incentives is actually paid, the impact on net sales would be 
recorded in the period that the change was identified. Assuming our current mix of sales incentives, a 10% change in 
sales incentives would have affected our earnings by approximately $5 million to $7 million per year for each of the prior 
three fiscal years. 

Under terms of certain previous U.S. government contracts, there were price reduction clauses and provisions for 
potential price reductions which are estimated at the time of sale based upon history and experience, and finalized after 
completion of U.S. government audits. Potential reductions may be attributed to a change in projected sales volumes or 
plant efficiencies which impact overall costs. Given our current price reduction reserve for government contracts, a 10% 
adjustment in our price reduction reserve would have affected our earnings by approximately $6 million per year for each 
of the prior three fiscal years. Beginning in 2014, all of our contracts with the U.S. government are firm fixed price 
contracts, which do not contain price reduction clauses and provisions. 

Further information is provided in NOTE 2 “Summary of Significant Accounting Policies” of Notes to Consolidated 

Financial Statements included in Part II, Item 8, of this Annual Report on Form 10-K.  

Goodwill and Other Intangible Assets  

Goodwill is tested for impairment at the reporting unit level, which is the same as our one operating and reportable 

segment. We do not aggregate any components into our reporting unit. We have elected to perform our annual 
impairment test on October 31 of every year. A multi-step impairment test is performed on goodwill. In Step 0, we have 
the option to evaluate various qualitative factors to determine the likelihood of impairment. If we determine that the fair 
value is more likely than not less than the carrying value, then we are required to perform Step 1. If we do not elect to 
perform Step 0, we can voluntarily proceed directly to Step 1. In Step 1, we perform a quantitative analysis to compare the 
fair value of our reporting unit to our carrying value including goodwill. If the fair value of the reporting unit exceeds the 
carrying value of the net assets assigned to that unit, goodwill is not considered impaired, and we are not required to 
perform further testing. If the carrying value of a reporting unit’s goodwill exceeds its carrying value of net assets, then we 
would record an impairment loss equal to the difference. 

A qualitative assessment contains uncertainties because it requires management to make assumptions and to apply 

judgment to assess business changes, economic outlook, financial trends and forecasts, growth rates, credit ratings, 
equity ratings, discount rates, industry data and other relevant qualitative factors.   

A quantitative analysis contains uncertainties because it is performed utilizing a discounted cash flow model which 

includes key assumptions, such as net sales growth derived from market information, industry reports, marketing 
programs and future new product introductions; operating margin improvements derived from cost reduction programs 
and fixed cost leverage driven by higher sales volumes; and a risk-adjusted discount rate.     

Events or circumstances that could unfavorably impact the key assumptions include lower net sales driven by 
market conditions, our inability to execute on marketing programs and/or a delay in the introduction of new products, lower 
gross margins as a result of market conditions or failure to obtain forecasted cost reductions, or a higher discount rate as 
a result of market conditions.      

42 

  
 
Goodwill impairment testing for 2017 was performed using the Step 0 analysis by assessing certain qualitative 
trends and factors. These trends and factors were compared to, and based on, the assumptions used in prior years. After 
reviewing the various qualitative factors mentioned above, our 2017 annual goodwill impairment test indicated that the fair 
value of the reporting unit more likely than not exceeded its carrying value, indicating no impairment. 

Other intangible assets have both indefinite and finite useful lives. Intangible assets with indefinite useful lives are 

not amortized but are tested annually for impairment. We have elected to perform our annual trade name impairment test 
on October 31 of every year and follow a similar multi-step impairment test that is performed on goodwill. While 
unpredictable and inherently uncertain, we believe the forecast estimates are reasonable and incorporate those 
assumptions that similar market participants would use in their estimates of fair value. After reviewing the various 
qualitative factors mentioned above, our annual 2017 trade name impairment test, as of October 31, 2017, indicated that 
the fair value of our trade name more likely than not exceeded the respective carrying value, indicating no impairment. 

Intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment when 

circumstances change that would create a triggering event. Assumptions and estimates about future values and 
remaining useful lives of our intangible and other long-lived assets are complex and subjective. They can be affected by a 
variety of factors, including external factors such as industry and economic trends, and internal factors, such as changes 
in our business strategy and internal forecasts. Although management believes the historical assumptions and estimates 
are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial 
results. Further information is provided in NOTE 2 “Summary of Significant Accounting Policies” and NOTE 5 “Goodwill 
and Other Intangible Assets” of Notes to Consolidated Financial Statements included in Part II, Item 8, of this Annual 
Report on Form 10-K.  

Impairment of Long-Lived Assets  

The carrying value of long-lived assets is evaluated whenever events or circumstances indicate that the carrying 
value of a long-lived asset may not be recoverable. Events or circumstances that would result in an impairment review 
primarily include a significant change in the use of an asset, or the planned sale or disposal of an asset. The asset would 
be considered impaired when there is no future use planned for the asset or the future net undiscounted cash flows 
generated by the asset or asset group are less than its carrying value. An impairment loss would be recognized based on 
the amount by which the carrying value exceeds fair value.  

Assumptions and estimates used to determine cash flows in the evaluation of impairment and the fair values used to 

determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and 
estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying 
value of long-lived assets and could result in an impairment charge. As a result of events and circumstances in the fourth 
quarter of 2017, we reviewed certain of our long-lived assets related to the production of the TC10 product. We completed 
a test for recoverability using the undiscounted cash flows of the TC10 product line. Due to continued weak demand 
conditions for the TC10 product, the future undiscounted cash flows of the related assets were less than the carrying 
value of those assets. We used a market approach to determine the fair value of the assets, resulting in a $32 million loss 
for the year ended December 31, 2017. There were no impairment charges for the year ended December 31, 2016. 

As a result of events and circumstances in the first quarter of 2015, we reviewed certain of our long-lived assets 

related to the production of the H3000 and H4000 electric hybrid-propulsion systems, resulting in a $1 million loss 
recorded for the year ended December 31, 2015. Deteriorating market conditions for hybrid-propulsion vehicles, 
principally as a result of decreased fuel costs, alternative fuels and other technologies, significantly contributed to the 
future cash flows of the related assets being less than the carrying value of those assets.  

Warranty  

Provisions for estimated expenses related to product warranties are made at the time products are sold. Warranty 

claims arise when a transmission fails while in service during the relevant warranty period. The warranty reserve is 
adjusted in Selling, general and administrative based on our current and historical warranty claims paid and associated 
repair costs. These estimates are established using historical information including the nature, frequency, and average 
cost of warranty claims and are adjusted as actual information becomes available. From time to time, we may initiate a 
specific field action program. As a result of the uncertainty surrounding the nature and frequency of specific field action 
programs, the liability for such programs is recorded when we commit to an action. We review and assess the liability for 
these programs on a quarterly basis. We also assess our ability to recover certain costs from our suppliers and record a 
receivable from the supplier when we believe a recovery is probable.  Warranty costs may differ from those estimated if 
actual claim rates are higher or lower than our historical rates. Further information is provided in NOTE 9 “Product 
Warranty Liabilities” of Notes to Consolidated Financial Statements included in Part II, Item 8, of this Annual Report on 
Form 10-K which contains a summary of the activity in our warranty liability account for 2017, 2016 and 2015 including 
adjustments to pre-existing warranties. 

43 

  
 
Pension and Post-retirement Benefit Plans  

Pension and OPEB costs are based upon various actuarial assumptions and methodologies as prescribed by 
authoritative accounting guidance. These assumptions include discount rates, expected return on plan assets, health care 
cost trend rates, inflation, rate of compensation increases, population demographics, mortality rates and other factors. We 
review all actuarial assumptions on an annual basis.  

A change in the discount rate can have a significant impact on determining our benefit obligations. Our current 
discount rate is determined by matching the plans’ projected cash flows to a yield curve based on long-term, fixed income 
debt instruments available as of the measurement date of December 31, 2017. The effect of a one percentage point 
decrease in the assumed discount rate would result in an increase in the December 31, 2017 defined benefit pension 
plans obligation of approximately $22 million. Similarly, a one percentage point decrease in the assumed discount rate 
would result in an increase in the December 31, 2017 OPEB obligation of approximately $15 million. 

Further information is provided in NOTE 13 “Employee Benefit Plans” of Notes to Consolidated Financial Statements 

included in Part II, Item 8, of this Annual Report on Form 10-K, which contains our review on various actuarial 
assumptions. 

Income Taxes  

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are 
recognized for the expected future tax consequences attributable to temporary differences between the financial 
statement carrying amounts of existing assets and liabilities and their respective tax bases. The future tax benefits 
associated with operating loss and tax credit carryforwards are recognized as deferred tax assets. Deferred tax assets 
and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those 
temporary differences are expected to be recovered or settled.  

On December 22, 2017, the Tax Act was enacted into law. The Tax Act makes broad and complex changes to the 

U.S. tax code that impact the Company, most notably a reduction of the U.S. corporate income tax rate from 35% to 21% 
for tax years beginning after December 31, 2017. The Tax Act also makes other changes including, but not limited to, the 
acceleration of depreciation for certain assets placed into service after September 27, 2017 as well as a one-time deemed 
repatriation tax on undistributed foreign earnings and profits. Beginning in 2018, the Tax Act makes other changes 
impacting us such as additional limitations on executive compensation, the repeal of the domestic manufacturing 
deduction and qualifications around certain research and development expenditures. 

As of December 31, 2017, our U.S. federal income tax deductions related to our intangible assets were 

approximately $315 million annually through 2021 and approximately $185 million in 2022. Excluding our intangible asset 
deductions, our expected tax payments would have increased by approximately $110 million for the year ended 
December 31, 2017.  

The need to establish a valuation allowance against the deferred tax assets is assessed periodically based on a 

more-likely-than-not realization threshold, in accordance with the Financial Accounting Standard Board’s (“FASB”) 
authoritative accounting guidance on income taxes. Appropriate consideration is given to all positive and negative 
evidence related to that realization. This assessment considers, among other matters, the nature, frequency and severity 
of recent losses, forecasts of future profitability, the duration of statutory carryforward periods, and experience with tax 
attributes expiring unused and tax planning alternatives. The weight given to these considerations depends upon the 
degree to which they can be objectively verified.  

Further information on income taxes is provided in NOTE 14 “Income Taxes” of Notes to Consolidated Financial 

Statements included in Part II, Item 8, of this Annual Report on Form 10-K. 

Off-Balance Sheet Arrangements 

We are not a party to any off-balance sheet arrangements.

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk 

Our exposure to market risk consists of changes in interest rates, foreign currency rate fluctuations and movements 

in commodity prices.  

Interest Rate Risk  

We are subject to interest rate market risk in connection with a portion of our long-term debt. Our principal interest 

rate exposure relates to outstanding amounts under our Senior Secured Credit Facility. Our Senior Secured Credit Facility 
provides for variable rate borrowings of up to $1,709 million including $533 million under our Revolving Credit Facility, net 
of $17 million of letters of credit. A one-eighth percent increase or decrease in assumed interest rates for the Senior 
Secured Credit Facility, if fully drawn as of December 31, 2017, would have an impact of approximately $2 million on 
interest expense. As of December 31, 2017, we had no outstanding borrowings against the Revolving Credit Facility. 

During December 2017, we terminated interest rate swap contracts with notional values totaling $800 million. The 

transaction resulted in $13 million of interest expense. As of December 31, 2017, we are not party to any interest rate 
swaps. 

Refer to NOTE 7 “Debt” and NOTE 8 “Derivatives” of Notes to Consolidated Financial Statements included in Part II, 

Item 8, of this Annual Report on Form 10-K.  

Exchange Rate Risk  

While our net sales and costs are denominated primarily in U.S. Dollars, net sales, costs, assets and liabilities are 

generated in other currencies including Japanese Yen, Euro, Indian Rupee, Brazilian Real, Chinese Yuan Renminbi, 
Canadian Dollar and Hungarian Forint. The expansion of our business outside North America may further increase the 
risk that cash flows resulting from these activities may be adversely affected by changes in currency exchange rates.  

Assuming current levels of foreign currency transactions, a 10% aggregate increase or decrease in the Japanese 

Yen, Euro, Indian Rupee and Chinese Yuan Renminbi would correspondingly change our earnings, net of tax, by an 
estimated $5 million per year. We believe other exposure to foreign currencies is immaterial. 

Commodity Price Risk  

We are subject to changes in our cost of sales caused by movements in underlying commodity prices. 

Approximately two-thirds of our cost of sales consists of purchased components with significant raw material content. A 
substantial portion of the purchased parts are made of aluminum and steel. The cost of aluminum parts includes an 
adjustment factor on future purchases for fluctuations in aluminum prices based on accepted industry indices. In addition, 
a substantial amount of steel-based contracts also include an index-based component. As our costs change, we are able 
to pass through a portion of the changes in commodity prices to certain of our customers according to our LTSAs. We 
historically have not entered into long-term purchase contracts related to the purchase of aluminum and steel. Assuming 
current levels of commodity purchases, a 10% increase or decrease in the price of aluminum and steel would 
correspondingly change our earnings by approximately $2 million and $5 million per year, respectively. 

Many of our LTSAs have incorporated a cost-sharing arrangement related to potential future commodity price 
fluctuations. For purposes of the sensitivity analysis above, the impact of these cost sharing arrangements has not been 
included.

ITEM 8. Financial Statements and Supplementary Data 

Report of Independent Registered Public Accounting Firm 

To the Board of Directors and Stockholders of Allison Transmission Holdings, Inc. 

Opinions on the Financial Statements and Internal Control over Financial Reporting 

We have audited the accompanying consolidated balance sheets of Allison Transmission Holdings, Inc. and its 
subsidiaries as of December 31, 2017 and 2016, and the related consolidated statements of comprehensive income, 
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, including the 
related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as 
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 (COSO).   

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 their operations and their cash flows for 
each of the three years in the period ended December 31, 2017 in conformity with accounting principles generally 
accepted in the United States of America.  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 COSO. 

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 Management's Report on Internal Control over Financial Reporting appearing under Item 9A.  Our 
responsibility is to express opinions on the Company’s consolidated financial statements and 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 
generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies 
and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 

46 

  
 
 
 
 
 
 
 
 
 
 
 
 
 
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 (iii) 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.

Allison Transmission Holdings, Inc. 
Notes to Consolidated Financial Statements  

NOTE 1.    OVERVIEW  

Overview  

Allison Transmission Holdings, Inc. and its subsidiaries (“Allison” or the “Company”) design and manufacture 
commercial and defense fully-automatic transmissions. The business was founded in 1915 and has been headquartered 
in Indianapolis, Indiana since inception. Allison was an operating unit of General Motors Corporation (“Old GM”) from 
1929 until 2007, when Allison once again became a stand-alone company. In March 2012, Allison began trading on the 
New York Stock Exchange under the symbol, “ALSN”.  

The Company has approximately 2,700 employees and 13 different transmission product lines. Although 

approximately 79% of revenues were generated in North America in 2017, the Company has a global presence by serving 
customers in Europe, Asia, South America and Africa. The Company serves customers through an independent network 
of approximately 1,400 independent distributor and dealer locations worldwide. 

NOTE 2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  

Basis of Presentation and Principles of Consolidation  

The consolidated financial statements have been prepared in accordance with accounting principles generally 

accepted in the United States of America (“GAAP”). The information herein reflects all normal recurring material 
adjustments, which are, in the opinion of management, necessary for a fair statement of the results for the periods 
presented. The consolidated financial statements herein consist of all wholly-owned domestic and foreign subsidiaries 
with all significant intercompany transactions eliminated. 

These consolidated financial statements present the financial position, results of comprehensive income, cash flows 

and statements of equity. The presentation of certain prior year disclosures has been modified to conform to the current 
year presentation, as commencing in the first quarter of 2017, the Company elected to report financial data in whole 
millions of dollars, except as otherwise noted. 

Use of Estimates  

The preparation of financial statements in conformity with GAAP requires management to make estimates and 

assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities and 
the reported amounts of revenue and expenses. Estimates include, but are not limited to, sales allowances, government 
price adjustments, fair market values and future cash flows associated with goodwill, indefinite life intangibles, long-lived 
asset impairment tests, useful lives for depreciation and amortization, warranty liabilities, environmental liabilities, 
determination of discount and other assumptions for pension and other postretirement benefit expense, income taxes and 
deferred tax valuation allowances, derivative valuation, and contingencies. The Company’s accounting policies involve the 
application of judgments and assumptions made by management that include inherent risks and uncertainties. Actual 
results could differ materially from these estimates. Changes in estimates are recorded in results of operations in the 
period that the events or circumstances giving rise to such changes occur.  

Segment Reporting  

In accordance with the Financial Accounting Standards Board’s (“FASB”) authoritative accounting guidance on 
segment reporting, the Company has one operating segment and reportable segment. The Company is in one line of 
business, which is the manufacture and distribution of fully-automatic transmissions. 

Cash and Cash Equivalents  

Cash equivalents are defined as short-term, highly-liquid investments with original maturities of 90 days or less. 
Under the Company’s cash management system, checks issued but not presented to banks may result in book overdraft 
balances for accounting purposes and are classified within Accounts payable in the Consolidated Balance Sheets. The 
change in book overdrafts is reported as a component of operating cash flows for Accounts payable.  

52 

  
 
 
Marketable Securities  

The Company determines the appropriate classification of all marketable securities as “held-to-maturity,” “available-

for-sale” or “trading” at the time of purchase, and re-evaluates such classifications as of each balance sheet date. As of 
December 31, 2017, the Company’s marketable securities are classified as trading. 

Trading securities are carried at fair value with the unrealized gain or loss recognized in Other (expense) income, 

net. The fair value of the Company’s investment securities is determined by currently available market prices. See NOTE 
6 “Fair Value of Financial Instruments” for more details.  

Inventories  

Inventories are stated at the lower of cost and net realizable value. The Company determines cost using the first-in, 

first-out method. The Company analyzes inventory on a quarterly basis to determine whether it is excess or obsolete 
inventory. Any decline in carrying value of estimated excess or obsolete inventory is recorded as a reduction of inventory 
and as an expense included in Cost of sales in the period it is identified. 

Property, Plant and Equipment  

Property, plant and equipment are recorded at cost less accumulated depreciation. Depreciation expense is 

recorded using the straight-line method over the following estimated lives:  

Land improvements......................................................................................................................  
Buildings and building improvements ..........................................................................................  
Machinery and equipment ............................................................................................................  
Software .......................................................................................................................................  
Special tools .................................................................................................................................  

5 – 30 
10 – 40 
2 – 20 
2 – 5 
2 – 10 

Range in Years  

Software represents the costs of software developed or obtained for internal use. Software costs are amortized on a 

straight-line basis over their estimated useful lives. Software assets are reviewed for impairment when events or 
circumstances indicate that the carrying value may not be recoverable over the remaining lives of the assets. Upgrades 
and enhancements are capitalized if they result in added functionality, which enables the software to perform tasks it was 
previously incapable of performing. Software maintenance, training, data conversion and business process reengineering 
costs are expensed in the period in which they are incurred.  

Special tooling represents the costs to design and develop tools, dies, jigs and other items owned by the Company 

and used in the manufacture of components by suppliers under long-term supply agreements. Special tooling is 
depreciated over the tool’s expected life. Special tooling used in the development of new technology is expensed as 
incurred. Engineering, testing and other costs incurred in the design and development of production parts are expensed 
as incurred.  

Impairment of Long-Lived Assets  

The carrying value of long-lived assets is evaluated whenever events or circumstances indicate that the carrying 
value of an asset may not be recoverable. Events or circumstances that would result in an impairment review primarily 
include a significant change in the use of an asset or the planned sale or disposal of an asset. The asset would be 
considered impaired when there is no future use planned for the asset or the future net undiscounted cash flows 
generated by the asset or asset group are less than its carrying value. An impairment loss would be recognized based on 
the amount by which the carrying value exceeds fair value.  

Assumptions and estimates used to determine cash flows in the evaluation of impairment and the fair values used to 

determine the impairment are subject to a degree of judgment and complexity. Any changes to the assumptions and 
estimates resulting from changes in actual results or market conditions from those anticipated may affect the carrying 
value of long-lived assets and could result in an impairment charge. 

As a result of events and circumstances in the fourth quarter of 2017, the Company reviewed certain of its long-lived 

assets related to the production of the TC10 product, resulting in a $32 million impairment loss recorded for the year 
ended December 31, 2017. Continued weak demand conditions for the TC10 product contributed to the future cash flows 
of the related assets being less than the carrying value of those assets. 

There were no impairment charges for the year ended December 31, 2016. 

53 

  
 
 
 
  
  
The Company recorded a $1 million impairment loss during 2015 on certain of its long-lived assets related to the 

production of the H3000 and H4000 electric hybrid-propulsion systems. Deteriorating market conditions for hybrid-
propulsion vehicles, principally as a result of decreased fuel costs, alternative fuels and other technologies, significantly 
contributed to the future cash flows of the related assets being less than the carrying value of those assets. 

Goodwill and Other Intangible Assets  

Goodwill represents the excess of purchase price paid over the fair value of net assets acquired. In accordance with 
the FASB’s authoritative accounting guidance on goodwill, the Company does not amortize goodwill but rather evaluates it 
for impairment on an annual basis, or more often if events or circumstances change that could cause goodwill to become 
impaired. Goodwill is tested for impairment at the reporting unit level, which is the same as the Company’s one operating 
and reportable segment. The Company does not aggregate any components into its reporting unit. The Company has 
elected to perform its annual goodwill impairment test on October 31 of every year using a multi-step impairment test. In 
Step 0, the Company has the option to evaluate various qualitative factors to determine the likelihood of impairment. If 
determined that the fair value is more likely than not less than the carrying value, then the Company is required to perform 
Step 1. If the Company does not elect to perform Step 0, it can voluntarily proceed directly to Step 1. In Step 1, the 
Company performs a quantitative analysis to compare the fair value of its reporting unit to its carrying value including 
goodwill. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is 
not considered impaired, and the Company is not required to perform further testing. If the carrying value of a reporting 
unit’s goodwill exceeds its carrying value of net assets, then the Company would record an impairment loss equal to the 
difference. 

Goodwill impairment testing for 2017 was performed using the Step 0 analysis of certain trends and factors. The 

Company’s qualitative assessment included an assessment of business changes, economic outlook, financial trends and 
forecasts, growth rates, credit ratings, equity ratings, discount rates, industry data and other relevant qualitative factors. 
Events or circumstances that could unfavorably impact the key assumptions include lower net sales driven by market 
conditions, our inability to execute on marketing programs and/or growth initiatives, lower gross margins as a result of 
market conditions or failure to obtain forecasted cost reductions, or a higher discount rate as a result of market conditions. 
While unpredictable and inherently uncertain, the Company believes the forecast estimates were reasonable and 
incorporate assumptions that similar market participants would use in their estimates of fair value. These trends and 
factors were compared to, and based on, the assumptions used in prior years. After reviewing various qualitative factors, 
the Company’s 2017 annual goodwill impairment test indicated that the fair value of the reporting unit more likely than not 
exceeded its carrying value, indicating no impairment. Refer to NOTE 5 “Goodwill and Other Intangible Assets” for further 
information. 

Other intangible assets have both indefinite and finite useful lives. Intangible assets with indefinite useful lives, such 

as the Company’s trade name, are not amortized but are tested annually for impairment. The Company has elected to 
perform our annual trade name impairment test on October 31 of every year and follow a similar multi-step impairment 
test to that performed on goodwill. Events or circumstances that could unfavorably impact the key assumptions include 
lower net sales driven by market conditions, our inability to execute on marketing programs and/or delay in introduction of 
new products, and higher discount rate as a result of market conditions. While unpredictable and inherently uncertain, the 
Company believes the forecast estimates are reasonable and incorporate those assumptions that similar market 
participants would use in their estimates of fair value. After reviewing various qualitative factors, the Company’s annual 
2017 trade name impairment test, as of October 31, 2017, indicated that the fair value of the trade name more likely than 
not exceeded its carrying value, indicating no impairment. Refer to NOTE 5 “Goodwill and Other Intangible Assets” for 
further information. 

Intangible assets with finite lives are amortized over their estimated useful lives and reviewed for impairment when 

circumstances change that would create a triggering event. Customer relationships are amortized over the life in which 
expected benefits are to be consumed. The other remaining finite life intangibles are amortized on a straight-line basis 
over their useful lives. The Company evaluates the remaining useful life of the other intangible assets on a periodic basis 
to determine whether events or circumstances warrant a revision to the remaining useful life. Assumptions and estimates 
about future values and remaining useful lives of the Company’s intangible and other long-lived assets are complex and 
subjective. They can be affected by a variety of factors, including external factors such as industry and economic trends, 
and internal factors, such as changes in the Company’s business strategy and internal forecasts. Although management 
believes the historical assumptions and estimates are reasonable and appropriate, different assumptions and estimates 
could materially impact the Company’s reported financial results. NOTE 5 “Goodwill and Other Intangible Assets” provides 
further information.

Deferred Financing Costs  

The debt issuance costs related to line-of-credit arrangements is presented as a component of other non-current 
assets. The debt issuance costs related to other types of debt instruments such as notes and loans are presented as a 
component of long-term debt. Deferred financing costs continue to be amortized over the life of the related debt using the 
effective interest method. Amortization of deferred financing costs is recorded as part of interest expense and totaled $6 
million, $7 million and $8 million for the years ended December 31, 2017, 2016 and 2015, respectively.   

Financial Instruments  

The Company’s cash equivalents are invested in U.S. government backed securities and recorded at fair value in 

the Consolidated Balance Sheets. The carrying values of accounts receivable and accounts payable approximate fair 
value due to their short-term nature.  The Company’s financial derivative instruments, including interest rate swaps and 
foreign currency and commodity forward contracts are carried at fair value on the Consolidated Balance Sheets. Refer to 
NOTE 6 “Fair Value of Financial Instruments” for more detail.  The Company’s long-term debt obligations are carried at 
historical amounts with the Company providing fair value disclosure in NOTE 7 “Debt”.  

Insurable Liabilities  

The Company records liabilities for its medical, workers’ compensation, long-term disability, product, general and 

auto liabilities. The determination of these liabilities and related expenses is dependent on claims experience. For most of 
these liabilities, claims incurred but not yet reported are estimated based upon historical claims experience.   

Revenue Recognition  

The Company records sales when title has transferred to the customer, there is evidence of an agreement, the sales 

price is fixed or determinable, delivery has occurred or services have been rendered, and collectability is reasonably 
assured. The Company sells extended transmission coverage (“ETC”) for which sales are deferred. ETC sales are 
recognized ratably over the period of the ETC, which typically ranges from two to five years after initial sale. Costs 
associated with ETC programs are recorded as incurred during the extended period. Distributor and customer sales 
incentives, consisting of allowances and other rebates, are estimated at the time of sale based upon the Company’s 
history and experience and are recorded as a reduction to Net sales. Incentive programs are generally product specific or 
region specific. Some factors used in estimating the cost of incentives include the number of transmissions that will be 
affected by the incentive program and rate of acceptance of any incentive program. If the actual number of affected 
transmissions differs from this estimate, or if a different mix of incentives is actually paid, the impact on Net sales would 
be recorded in the period that the change was identified. Consideration given to commercial customers recorded as a 
reduction of Net sales in the Consolidated Statements of Comprehensive Income included $66 million, $58 million, and 
$47 million for the years ended December 31, 2017, 2016 and 2015, respectively. 

Sales under U.S. government production contracts are recorded when the product is accepted, title has transferred 

to the U.S. government, the sales price is fixed or determinable, delivery has occurred, and any other terms of the 
contract have been met. Deferred revenue arises from cash received in advance of the culmination of the earnings 
process and is recognized as revenue in future periods when the applicable revenue recognition criteria have been met. 
Under the terms of previous U.S. government contracts, there were certain price reduction clauses and provisions for 
potential price reductions which were estimated at the time of sale based upon the Company’s history and experience and 
were recorded as a reduction to Net sales. Potential reductions may be attributed to a change in projected sales volumes 
or plant efficiencies which impact overall costs. As of each of December 31, 2017 and 2016, the Company had $56 million 
recorded in the price reduction reserve account. 

The Company engages in licensing agreements with certain third parties for the use of the Company’s intellectual 

property. Deferred revenue arises from cash received in advance of the period of use of the intellectual property. Revenue 
is recognized over the license period as it is earned. 

The Company classifies shipping and handling billed to customers in Net sales and shipping and handling costs in 

Cost of sales, in accordance with authoritative accounting guidance. 

The Company contracts with various third parties to provide engineering services. These services are recorded as 
Net sales in accordance with the terms of the contract. The saleable engineering recorded was $3 million, $3 million and 
$4 million for the years ended December 31, 2017, 2016 and 2015, respectively. The associated costs are recorded in 
Cost of sales. 

55 

  
 
Warranty  

Provisions for estimated expenses related to product warranties are made at the time products are sold. Warranty 

claims arise when a transmission fails while in service during the relevant warranty period. The warranty reserve is 
adjusted in Selling, general and administrative based on the Company’s current and historical warranty claims paid and 
associated repair costs. These estimates are established using historical information including the nature, frequency, and 
average cost of warranty claims and are adjusted as actual information becomes available. From time to time, the 
Company may initiate a specific field action program. As a result of the uncertainty surrounding the nature and frequency 
of specific field action programs, the liability for such programs is recorded when the Company commits to an action. The 
Company reviews and assesses the liability for these programs on a quarterly basis. The Company also assesses its 
ability to recover certain costs from its suppliers and records a receivable from the supplier when it believes a recovery is 
probable. Warranty costs may differ from those estimated if actual claim rates are higher or lower than our historical rates. 

Research and Development  

The Company incurs costs in connection with research and development programs that are expected to contribute 

to future earnings. Such costs are charged to Engineering — research and development as incurred.  

Environmental 

The Company accrues costs related to environmental matters when it is probable that the Company has incurred a 
liability related to a contaminated site and the costs can be reasonably estimated. For additional information, see NOTE 
16 “Commitments and Contingencies”. 

Foreign Currency Translation  

Most of the subsidiaries outside the United States prepare financial statements in currencies other than the 
U.S. Dollar. The functional currency for all of these subsidiaries is the local currency, except for the Company’s Hong 
Kong and Middle East subsidiaries which currently use the U.S. Dollar as their functional currency. Balances are 
translated at period-end exchange rates for assets and liabilities and monthly weighted-average exchange rates for 
revenues and expenses. The translation gains and losses are stated as a component of Accumulated Other 
Comprehensive Loss (“AOCL”) as disclosed in NOTE 15 “Accumulated Other Comprehensive Loss”.  

Derivative Instruments  

In the normal course of business, the Company is exposed to fluctuations in interest rates, foreign currency 
exchange rates, and commodity prices. The risk is managed through the use of financial derivative instruments including 
interest rate swaps and commodity and foreign currency forward contracts, when appropriate. Despite the fact that the 
Company either has not elected or does not qualify for hedge accounting treatment on all of its derivative instruments, the 
contracts are used strictly as an economic hedge and not for speculative purposes. As necessary, the Company adjusts 
the values of the derivative instruments for counter-party or credit risk. NOTE 8 “Derivatives” provides further information 
on the accounting treatment of the Company’s derivative instruments. 

Income Taxes  

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are 
recognized for the expected future tax consequences attributable to temporary differences between the financial 
statement carrying amounts of existing assets and liabilities and their respective tax bases. The future tax benefits 
associated with operating loss and tax credit carryforwards are recognized as deferred tax assets. Deferred tax assets 
and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those 
temporary differences are expected to be recovered or settled.  

The need to establish a valuation allowance against the deferred tax assets is assessed periodically based on a 
more-likely-than-not realization threshold, in accordance with the FASB’s authoritative accounting guidance on income 
taxes. Appropriate consideration is given to all positive and negative evidence related to that realization. This assessment 
considers, among other matters, the nature, frequency and severity of recent losses, forecasts of future profitability, the 
duration of statutory carryforward periods, and experience with tax attributes expiring unused and tax planning 
alternatives. The weight given to these considerations depends upon the degree to which they can be objectively verified.  

56 

  
 
Stock-Based Compensation  

In March 2015, the Company’s Board of Directors adopted and, in May 2015, the Company’s stockholders approved 

the Allison Transmission Holdings, Inc. 2015 Equity Incentive Award Plan (“2015 Plan”), which became effective on May 
14, 2015. Under the 2015 Plan, certain employees (including executive officers), consultants and directors are eligible to 
receive equity-based compensation, including non-qualified stock options, incentive stock options, restricted stock, 
dividend equivalents, stock payments, restricted stock units (“RSU”s), performance awards, stock appreciation rights and 
other equity-based awards, or any combination thereof. The 2015 Plan limits the aggregate number of shares of common 
stock available for issue to 15.3 million and will expire on, and no option or other equity award may be granted pursuant to 
the 2015 Plan after, the tenth anniversary of the date the 2015 Plan was approved by the Board of Directors. 

Prior to the adoption of the 2015 Plan, the Company’s equity-based awards were granted under the Allison 
Transmission Holdings, Inc. 2011 Equity Incentive Award Plan (“2011 Plan”) and the Equity Incentive Plan of Allison 
Transmission Holdings, Inc. (“Equity Plan” and, together with the 2011 Plan, the “Prior Plans”). As of the effective date of 
the 2015 Plan, no new awards will be granted under the Prior Plans, but the Prior Plans will continue to govern the equity 
awards issued under the Prior Plans. 

RSUs are recorded at fair market value at the date of grant and vest upon continued performance of services by the 

RSU holders over one to three years. Restricted stock awards are recorded at fair market value at the date of grant and 
the restrictions lapse upon continued performance by the restricted stock holders on the vest date which generally occurs 
over one, two or three years. Performance awards are recorded at fair value based on a Monte-Carlo pricing model and 
the restrictions lapse on the date the Compensation Committee of the Board of Directors determines the number of 
shares that shall vest based on the total stockholder return of the Company relative to the specified peer group. Non-
qualified stock options are recorded at fair value using a Black-Scholes option pricing model and vest upon the continued 
performance of services by the option holder on the third anniversary of the grant date for awards under the 2015 Plan. 

The Company has made a policy election under applicable accounting guidance to account for forfeitures as a 

reduction of stock-based compensation expense when the forfeiture actually occurs. 

Restricted stock and RSUs were granted to certain employees and directors at fair market value on the date of 

grant. The restrictions lapse upon continued performance by the restricted stock or RSU holders on the vest date which 
generally occurs over one, two or three years. Restricted stock and RSU incentive compensation expense recorded was 
$7 million, $2 million and $2 million for the years ended December 31, 2017, 2016 and 2015, respectively. 

Performance awards were granted to certain employees at fair value at the date of grant. The Company records the 
fair value of each performance award based on a Monte-Carlo pricing model. Performance award incentive compensation 
expense recorded was $3 million, $1 million and $1 million for the years ended December 31, 2017, 2016 and 2015, 
respectively. 

Stock options were granted to certain employees at fair value on the date of grant using a Black-Scholes option 
pricing model. Stock option incentive compensation expense recorded was $2 million, $3 million and $4 million for the 
years ended December 31, 2017, 2016 and 2015, respectively.  

Pension and Post-retirement Benefit Plans  

For pension and other post-retirement benefits (“OPEB”) plans in which employees participate, costs are determined 
within the FASB’s authoritative accounting guidance set forth in employers’ defined benefit pensions including accounting 
for settlements and curtailments of defined benefit pension plans, termination of benefits and accounting for post-
retirement benefits other than pensions. In accordance with the authoritative accounting guidance, the Company 
recognizes the funded status of its defined benefit pension plans and OPEB plan in its Consolidated Balance Sheets with 
a corresponding adjustment to AOCL, net of tax.  

Post-retirement benefit costs consist of service cost and interest cost on accrued obligations. Actuarial gains and 

losses on liabilities together with any prior service costs are charged (or credited) to income over the average remaining 
service lives of employees.  

The benefit cost components shown in the Consolidated Statements of Comprehensive Income are based upon 
various actuarial assumptions and methodologies as prescribed by authoritative accounting guidance. These assumptions 
include discount rates, expected return on plan assets, health care cost trend rates, inflation, rate of compensation 
increases, population demographics, mortality rates and other factors. The Company reviews all actuarial assumptions on 
an annual basis. Changes in key economic indicators can change these assumptions. These assumptions, along with the 
actual value of assets at the measurement date, will impact the calculation of pension expenses for the year.   

57 

  
 
Recently Adopted Accounting Pronouncements  

In May 2017, the FASB issued authoritative accounting guidance on accounting for modifications to the terms of 
employee stock compensation. The guidance clarifies which changes to terms or conditions of share-based payment 
awards require the entity to apply modification accounting. The guidance was adopted by the Company effective January 
1, 2018. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial 
statements.  

In March 2017, the FASB issued authoritative accounting guidance on the presentation of net periodic pension costs 

and net periodic postretirement benefit costs. The guidance clarifies the presentation of component costs within an 
employer’s financial statements and restricts component costs eligible for capitalization to the service cost component. 
The guidance was adopted by the Company effective January 1, 2018. 

In January 2017, the FASB issued authoritative accounting guidance on evaluation of goodwill for impairment. The 

guidance modifies the approach to assessing impairment from testing the implied fair value goodwill to testing the fair 
value of the reporting unit carrying the goodwill, which eliminates Step 2 of the prior evaluation guidance. The intent of this 
amendment is to reduce the cost and complexity of evaluating goodwill. The guidance was early adopted by the Company 
effective July 1, 2017. The adoption of this guidance did not have an impact on the Company’s consolidated financial 
statements. 

In October 2016, the FASB issued authoritative accounting guidance on the income tax consequences of intra-

company transfers other than inventory. This guidance addresses the timing of the recognition of current and deferred 
income taxes. Under this guidance, the recognition of current or deferred income taxes will occur at the time of the 
transfer of the asset. The guidance was adopted by the Company effective January 1, 2018. The adoption of this 
guidance is not expected to have a material impact on the Company’s consolidated financial statements. 

In August 2016, the FASB issued authoritative accounting guidance on the presentation and classification of certain 

cash receipts and cash payments on the statement of cash flows. The guidance specifically addresses cash flow issues 
with the objective of reducing the diversity in practice. The guidance was adopted by the Company effective January 1, 
2018. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial 
statements. 

In March 2016, the FASB issued authoritative accounting guidance on share-based payment awards to employees. 
The guidance involves several aspects of the accounting for share-based payment transactions, including the income tax 
consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The 
guidance was adopted by the Company effective January 1, 2017. Management recorded an excess tax benefit of $18 
million to income tax expense and as a component of operating cash flows for the year ended December 31, 2017, and 
made the accounting policy election to account for forfeitures in stock-based compensation as they occur. 

In January 2016, the FASB issued authoritative accounting guidance on the classification of equity securities with 

readily determinable fair values into different categories (e.g. trading or available-for-sale) and the requirement for equity 
securities to be measured at fair value with changes in fair value recognized in net income. The guidance was adopted by 
the Company effective January 1, 2018. The adoption of this guidance is not expected to have a material impact on the 
Company’s consolidated financial statements. 

In July 2015, the FASB issued authoritative accounting guidance to simplify the measurement of inventory. The 
guidance requires that inventory be measured at the lower of cost and net realizable value. When evidence exists that the 
net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the 
period in which it occurs. Inventory measured using last-in, first-out and the retail inventory method are not impacted by 
the new guidance. The guidance was adopted by the Company effective January 1, 2017. The adoption of this guidance 
did not have a material impact on the Company’s consolidated financial statements. 

In May 2014, the FASB issued authoritative accounting guidance on a company’s accounting for revenue from 
contracts with customers, which guidance has subsequently been amended. The guidance applies to all companies that 
enter into contracts with customers to transfer goods, services or nonfinancial assets. The guidance requires these 
companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that 
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance 
also requires disclosures regarding the nature, timing, amount and uncertainty of revenue that is recognized. The 
guidance allows either full or modified retrospective adoption. The guidance was adopted by the Company effective 
January 1, 2018 using the modified retrospective approach. Management expects that the revenue streams that will be 
impacted by the guidance, although immaterially, relate to non-standard transmission coverages. Certain contracts have 
also been reviewed individually for the potential impact. No significant changes or additions to the Company’s internal 
controls over financial reporting are expected as a result of implementing this guidance. The adoption of this guidance is 
not expected to have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Pronouncements 

In February 2016, the FASB issued authoritative accounting guidance on lease accounting. The guidance requires 
lessees to present right-of-use assets and lease liabilities on the balance sheet for all leases not considered short-term 
leases. Short-term leases are leases with a lease term of 12 months or less as long as the leases do not include options 
to purchase the underlying assets that the lessee is reasonably certain to exercise. The new guidance also introduces 
new disclosure requirements for leasing arrangements. The guidance will be effective for the Company in fiscal year 
2019, and the Company does not plan to early adopt. Management is currently evaluating the impact of this guidance on 
the Company’s consolidated financial statements.

Depreciation of property, plant and equipment was $80 million, $84 million and $88 million for the years ended 

December 31, 2017, 2016 and 2015, respectively.  

As a result of events and circumstances in the fourth quarter of 2017, the Company reviewed certain machinery and 

equipment and special tools related to the production of the TC10 product. The Company completed a test for 
recoverability using the undiscounted cash flows of the TC10 product line. Due to continued weak demand conditions for 
the TC10 product, the future undiscounted cash flows of the related assets were less than the carrying value of those 
assets. The Company used a market approach to determine the fair value of the assets, resulting in a $32 million loss for 
the year ended December 31, 2017. During 2015, the Company recorded an impairment of certain machinery and 
equipment and special tools associated with the production of the H3000 and H4000 electric hybrid-propulsion systems.

Amortization of intangible assets was $90 million, $92 million and $97 million for the years ended December 31, 

2017, 2016 and 2015, respectively.  

As of December 31, 2017 and 2016, the net carrying value of the Company’s Goodwill and Other intangible assets, 
net was $3,094 million and $3,183 million, respectively. The Company’s 2017 annual goodwill impairment test indicated 
that the fair value of the reporting unit exceeded its carrying value, indicating no impairment. 

As of December 31, 2015, the Company recorded a trade name impairment charge of $80 million. The impairment 

charge was a result of a decline in forecasted net sales for certain of the Company’s end markets. The trade name 
impairment did not result in any other charges to goodwill, other intangible assets or long-lived assets. 

Amortization expense related to other intangible assets for the next five years is expected to be (dollars in millions):

NOTE 6.    FAIR VALUE OF FINANCIAL INSTRUMENTS  

In accordance with the FASB’s authoritative accounting guidance on fair value measurements, fair value is the price 

(exit price) that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 
participants at the measurement date. The Company utilizes market data or assumptions that market participants would 
use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation 
technique. These inputs can be readily observable, market corroborated, or generally unobservable. The Company 
primarily applies the market approach for recurring fair value measurements and utilizes the best available information 
that maximizes the use of observable inputs and minimizes the use of unobservable inputs. The Company is able to 
classify fair value balances based on the observability of those inputs. The accounting guidance establishes a fair value 
hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted 
quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to 
unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy defined by the relevant guidance 
are as follows:  

Level 1 — Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. 
Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide 
pricing information on an ongoing basis. Level 1 primarily consists of financial instruments such as exchange-traded 
derivatives, listed equities and publicly traded bonds. 

Level 2 — Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly 
or indirectly observable as of the reported date. Level 2 includes financial instruments that are valued using quoted prices 
in markets that are not active and those financial instruments that are valued using models or other valuation 
methodologies. These models are primarily industry standard models that consider various assumptions, including quoted 
forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying 
instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the 
marketplace throughout the full term of the instrument, can be derived from observable data or are supported by 
observable levels at which transactions are executed in the marketplace. 

Level 3 — Pricing inputs include significant inputs that are generally less observable from objective sources. These 

inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. At 
each balance sheet date, the Company performs an analysis of all instruments subject to authoritative accounting 
guidance and includes, in Level 3, all of those whose fair value is based on significant unobservable inputs. As of 
December 31, 2017 and 2016, the Company did not have any Level 3 financial assets or liabilities. 

The Company’s assets and liabilities that are measured at fair value include cash equivalents, available-for-sale 
securities, derivative instruments, assets held in a rabbi trust and a deferred compensation obligation. The Company’s 
cash equivalents consist of short-term U.S. government backed securities. The Company’s available-for-sale securities 
consisted of ordinary shares of Torotrak plc (“Torotrak”) associated with a license and exclusivity agreement with 
Torotrak. Torotrak’s listed shares were traded on the London Stock Exchange under the symbol “TRK” until trading was 
suspended in December 2017, at which time the fair value was zero, and the Company realized a loss of $13 million for 
the year ended December 31, 2017. The Company’s derivative instruments consisted of interest rate swaps. The 
Company’s assets held in the rabbi trust consist principally of publicly available mutual funds and target date retirement 
funds. The Company’s deferred compensation obligation is directly related to the fair value of assets held in the rabbi 
trust. 

The Company’s valuation techniques used to calculate the fair value of cash and cash equivalents, available-for-sale 

securities, assets held in the rabbi trust and the deferred compensation obligation represent a market approach in active 
markets for identical assets that qualify as Level 1 in the fair value hierarchy. The Company’s valuation techniques used 
to calculate the fair value of derivative instruments represent a market approach with observable inputs that qualify as 
Level 2 in the fair value hierarchy. 

The Company uses valuations from the issuing financial institution for the fair value measurement of interest rate 
derivatives. The Company corroborates the valuation through the use of third-party valuation services using a standard 
replacement valuation model. The floating-to-fixed interest rate swaps are based on the London Interbank Offered Rate 
(“LIBOR”) which is observable at commonly quoted intervals. The fair values are included in other current and non-current 
assets and liabilities in the Consolidated Balance Sheets. The Company did not elect hedge accounting treatment for the 
interest rate swaps and, as a result, fair value adjustments were charged directly to Interest expense, net in the 
Consolidated Statements of Comprehensive Income.

As of December 31, 2017, the Company had $2,576 million of indebtedness associated with Allison Transmission, 
Inc.’s (“ATI”), the Company’s wholly-owned subsidiary, 5.0% Senior Notes due September 2024 (“5.0% Senior Notes”), 
ATI’s 4.75% Senior Notes due October 2027 (“4.75% Senior Notes”) and ATI’s Senior Secured Credit Facility (“Senior 
Secured Credit Facility”), which consists of the Senior Secured Credit Facility Term B-3 Loan due 2022 (“Term B-3 Loan”) 
and the Senior Secured Credit Facility revolving credit facility due 2021 (“Revolving Credit Facility”). 

The fair value of the Company’s long-term debt obligations as of December 31, 2017 was $2,622 million. The fair 
value is based on quoted Level 2 market prices of the Company’s debt as of December 31, 2017. It is not expected that 
the Company would be able to repurchase a significant amount of its debt at these levels. The difference between the fair 
value and carrying value of the long-term debt is driven primarily by trends in the financial markets. 

Senior Secured Credit Facility 

In March 2017, ATI entered into an amendment with the term loan lenders under its Senior Secured Credit Facility to 

lower the applicable margins on the Term B-3 Loan by 0.5%. The amendment also eliminated the minimum LIBOR floor 
and reduced the minimum floor applicable to the base rate from 1.75% to 1.00% on the Term B-3 Loan. The March 2017 
amendment was treated as a modification to the Senior Secured Credit Facility under GAAP, and thus the Company 
recorded $1 million as new deferred financing fees. 

In September 2017, ATI entered into a joinder agreement with the lenders under its Senior Secured Credit Facility to 

increase the available commitments under the Revolving Credit Facility from $450 million to $550 million. The joinder 
agreement was treated as a modification to the Revolving Credit Facility under GAAP.

The Senior Secured Credit Facility is collateralized by a lien on substantially all assets of the Company including all 

of ATI’s capital stock and all of the capital stock or other equity interest held by the Company, ATI and each of the 
Company’s existing and future U.S. subsidiary guarantors (subject to certain limitations for equity interests of foreign 
subsidiaries and other exceptions set forth in the terms of the Senior Secured Credit Facility). Interest on the Term B-3 
Loan, as of December 31, 2017, is either (a) 2.00% over the LIBOR or (b) 1.00% over the greater of the prime lending 
rate as quoted by the administrative agent and the federal funds effective rate published by the Federal Reserve Bank of 
New York plus 0.5%, provided that neither is below 1.00%. As of December 31, 2017, the Company elected to pay the 
lowest all-in rate of LIBOR plus the applicable margin, or 3.57%, on the Term B-3 Loan. The Senior Secured Credit 
Facility requires minimum quarterly principal payments on the Term B-3 Loan as well as prepayments from certain net 
cash proceeds of non-ordinary course asset sales and casualty and condemnation events and from a percentage of 
excess cash flow, if applicable. The minimum required quarterly principal payment on the Term B-3 Loan through its 
maturity date of September 2022 is $3 million. As of December 31, 2017, there had been no payments required for certain 
net cash proceeds of non-ordinary course asset sales and casualty and condemnation events. The remaining principal 
balance is due upon maturity. 

The Senior Secured Credit Facility also provides a Revolving Credit Facility, net of an allowance for up to $75 million 

in outstanding letters of credit commitments. Throughout the year ended December 31, 2017, the Company made 
periodic withdrawals and payments on the Revolving Credit Facility as part of its debt management plans. The maximum 
amount outstanding at any time during the year ended December 31, 2017 on the Revolving Credit Facility was $300 
million. As of December 31, 2017, the Company had $533 million available under the Revolving Credit Facility, net of $17 
million in letters of credit. Revolving credit borrowings bear interest at a variable base rate plus an applicable margin 
based on the Company’s total leverage ratio. Interest on the Revolving Credit Facility is either (a) 1.75% over the LIBOR 
or (b) 0.75% over the greater of the prime lending rate in effect on such day and the federal funds effective rate published 
by the Federal Reserve Bank of New York plus 0.5%, provided that neither is below 1.75%. In addition, there is an annual 
commitment fee, based on the Company’s total leverage ratio, on the average unused revolving credit borrowings 
available under the Revolving Credit Facility. Revolving credit borrowings are payable at the option of the Company 
throughout the term of the Senior Secured Credit Facility with the balance due in September 2021. 

The Senior Secured Credit Facility requires the Company to maintain a specified maximum total senior secured 
leverage ratio of 5.50x when revolving loan commitments remain outstanding on the Revolving Credit Facility at the end of 
a fiscal quarter. As of December 31, 2017, the Company had no revolving loans outstanding; however the Company 
would have been in compliance with the maximum total senior secured leverage ratio, achieving a 1.13x ratio. 
Additionally, within the terms of the Senior Secured Credit Facility, a senior secured leverage ratio at or below 4.00x 
results in the elimination of excess cash flow payments on the Senior Secured Credit Facility for the applicable year. The 
Senior Secured Credit Facility also provides certain financial incentives based on our total leverage ratio. A total leverage 
ratio at or below 4.00x results in a 25 basis point reduction to the applicable margin on the Revolving Credit Facility, and a 
total leverage ratio at or below 3.50x results in a 12.5 basis point reduction to the Revolving Credit Facility commitment 
fee and an additional 25 basis point reduction to the applicable margin on the Revolving Credit Facility. These reductions 
would remain in effect as long as the Company achieves a total leverage ratio at or below the related threshold. As of 
December 31, 2017, the Company’s total leverage ratio was 2.74x. 

In addition, the Senior Secured Credit Facility, among other things, includes customary restrictions (subject to 
certain exceptions) on the Company’s ability to incur certain indebtedness, grant certain liens, make certain investments, 
declare or pay certain dividends, or repurchase shares of the Company’s common stock. As of December 31, 2017, the 
Company is in compliance with all covenants under the Senior Secured Credit Facility. 

5.0% Senior Notes 

In September 2016, ATI completed an offering of $1,000 million of the 5.0% Senior Notes. The 5.0% Senior Notes 

were offered in a private placement exempt from registration under the Securities Act of 1933, as amended. The proceeds 
from the offering, together with cash on hand, were used to repay $1,200 million of the Term B-3 Loan plus accrued and 
unpaid interest and related transaction expenses. As a result of the offering, the Company recorded approximately $13 
million as deferred financing fees in the Consolidated Balance Sheets in September 2016.  

ATI may from time to time seek to retire the 5.0% Senior Notes through cash purchases and/or exchanges for equity 

securities, in open market purchases, privately negotiated transactions, contractual redemptions or otherwise. Such 
repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual 
restrictions and other factors. The amounts involved may be material. Prior to October 1, 2019, ATI may redeem up to 
40% of the 5.0% Senior Notes by paying a price equal to 100% of the principal amount being redeemed plus the 
applicable “make-whole” premium. At any time on or after October 1, 2019, ATI may redeem some or all of the 5.0% 
Senior Notes at specified redemption prices in the governing indenture. 

63 

  
 
 
The 5.0% Senior Notes are unsecured and are guaranteed by each of ATI’s domestic subsidiaries that is a borrower 
under or guarantees the Senior Secured Credit Facility and are unconditionally guaranteed, jointly and severally, by any of 
ATI’s future domestic subsidiaries that are borrowers under or guarantee the Senior Secured Credit Facility. None of ATI’s 
domestic subsidiaries currently guarantee its obligations under the Senior Secured Credit Facility, and therefore none of 
ATI’s domestic subsidiaries currently guarantee the 5.0% Senior Notes. The indenture governing the 5.0% Senior Notes 
contains negative covenants restricting or limiting the Company’s ability to, among other things: incur or guarantee 
additional indebtedness, incur liens, pay dividends on, redeem or repurchase the Company’s capital stock, make certain 
investments, permit payment or dividend restrictions on certain of the Company’s subsidiaries, sell assets, engage in 
certain transactions with affiliates, and consolidate or merge or sell all or substantially all of the Company’s assets. As of 
December 31, 2017, the Company was in compliance with all covenants under the indenture governing the 5.0% Senior 
Notes. 

4.75% Senior Notes 

In September 2017, ATI completed an offering of $400 million of 4.75% Senior Notes. The 4.75% Senior Notes were 
offered in a private placement exempt from registration under the Securities Act of 1933, as amended. The proceeds from 
the offering were used for general corporate purposes and to pay related transaction fees and expenses. As a result of 
the offering, the Company recorded approximately $5 million as deferred financing fees in the Consolidated Balance 
Sheets. 

ATI may from time to time seek to retire the 4.75% Senior Notes through cash purchases and/or exchanges for 
equity securities, in open market purchases, privately negotiated transactions, contractual redemptions or otherwise. Such 
repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual 
restrictions and other factors. The amounts involved may be material. Prior to October 1, 2020, ATI may redeem up to 
40% of the 4.75% Senior Notes by paying a price equal to 104.75% of the principal amount being redeemed. Prior to 
October 1, 2022, ATI may redeem some or all of the 4.75% Senior Notes by paying a price equal to 100.00% of the 
principal amount being redeemed, plus a “make-whole” premium. At any time on or after October 1, 2022, ATI may 
redeem some or all of the 4.75% Senior Notes at specified redemption prices in the governing indenture. 

The 4.75% Senior Notes are unsecured and are guaranteed by each of ATI’s domestic subsidiaries that is a 

borrower under or guarantees the Senior Secured Credit Facility and are unconditionally guaranteed, jointly and severally, 
by any of ATI’s future domestic subsidiaries that are borrowers under or guarantee the Senior Secured Credit Facility. 
None of ATI’s domestic subsidiaries currently guarantee its obligations under the Senior Secured Credit Facility, and 
therefore none of ATI’s domestic subsidiaries currently guarantee the 4.75% Senior Notes. The indenture governing the 
4.75% Senior Notes contains negative covenants restricting or limiting the Company’s ability to, among other things: incur 
or guarantee additional indebtedness, incur liens, pay dividends on, redeem or repurchase the Company’s capital stock, 
make certain investments, permit payment or dividend restrictions on certain of the Company’s subsidiaries, sell assets, 
engage in certain transactions with affiliates, and consolidate or merge or sell all or substantially all of the Company’s 
assets. As of December 31, 2017, the Company was in compliance with all covenants under the indenture governing the 
4.75% Senior Notes.

NOTE 8.    DERIVATIVES  

The Company is exposed to certain financial risk from volatility in interest rates, foreign exchange rates and 
commodity prices. The risk is managed through the use of financial derivative instruments including interest rate swaps, 
foreign currency swaps and commodity swaps, when appropriate. Currently, the Company does not have any derivative 
instruments. The Company’s derivative instruments outstanding during 2017 were used strictly as an economic hedge 
and not for speculative purposes. As necessary, the Company adjusts the values of the derivative instruments for counter-
party or credit risk. 

Interest Rate  

The Company is subject to interest rate risk related to the Senior Secured Credit Facility and entered into interest 

rate swap contracts that were based on the LIBOR to manage a portion of this exposure. The Company did not elect 
hedge accounting treatment for these derivatives, and as a result, fair value adjustments were charged directly to Interest

During 2017, 2016 and 2015, the Company recorded approximately $1 million, $1 million and $9 million, 

respectively, of adjustments to the product warranty liabilities as a result of specific field action programs. As a result of 
the uncertainty surrounding the nature and frequency of specific field action programs, these liabilities will change as 
additional field information becomes available. 

The remaining adjustments to the total liability in 2017, 2016 and 2015, excluding the Dual Power Inverter Module 
(“DPIM”) as discussed below, were the result of general changes in estimates for various products as additional claims 
data and field information became available.  

Dual Power Inverter Module 

During June 2007, Old GM recognized the estimated cost of replacing the DPIM used on H 40/50 EP electric hybrid 

systems. Certain units were falling short of their expected service life and the Company’s predecessor, Allison 
Transmission, an operating unit of Old GM, decided to cover repair or replacement for an extended period. The Company 
is responsible for the first $12 million of qualified cost while General Motors Company (“GM”) is responsible for the next 
$34 million of costs, with any amount over $46 million being shared one-third by the Company and two-thirds by GM for 
shipments through June 30, 2009. As of December 31, 2017 and 2016, the Company’s remaining DPIM liability was $4 
million and $6 million, respectively, and the related receivable owed by GM to the Company was $3 million and $3 million, 
respectively.  

NOTE 10.    DEFERRED REVENUE 

As of December 31, 2017, the current and non-current deferred revenue were $41 million and $75 million, 
respectively. As of December 31, 2016, the current and non-current deferred revenue were $27 million and $66 million, 
respectively. Deferred revenue activity consists of the following (dollars in millions):

NOTE 13.    EMPLOYEE BENEFIT PLANS  

The Company’s hourly defined benefit pension plan generally provides benefits of negotiated, stated amounts for 

each year of service as well as significant supplemental benefits for employees who retire with 30 years of service before 
normal retirement age. Any difference between actual and expected returns on assets during a year and actuarial gains 
and losses on liabilities together with any prior service costs are charged (or credited) to income over the average 
remaining service lives of employees. The benefit cost components shown in the Consolidated Statements of 
Comprehensive Income are based upon certain data specific to the Company, actuarial assumptions that were used for 
accounting disclosures, and certain allocation methodologies such as population demographics. 

For all hourly employees hired after May 18, 2008, the defined benefit pension plan was replaced with a defined 

contribution pension plan, and the company-sponsored retiree healthcare was also eliminated for those hired after 
May 18, 2008. The charge to expense for the hourly defined contribution pension plan was $2 million for each of the years 
ended December 31, 2017, 2016 and 2015. 

The Company’s salaried defined benefit plan covering salaried employees with a service date prior to January 1, 

2001 is generally based on years of service and compensation history. Any difference between actual and expected 
returns on assets during a year and actuarial gains and losses on liabilities together with any prior service costs are 
charged (or credited) to income over the average remaining service lives of employees. The benefit cost components 
shown in the Consolidated Statements of Comprehensive Income are based upon certain data specific to the Company, 
actuarial assumptions that were used for accounting disclosures, and certain allocation methodologies such as population 
demographics. 

The Company’s salaried defined contribution retirement savings plan requires the Company to match employee 

contributions up to certain predefined limits based upon eligible base salary. In addition to the matching contribution, the 
Company is required to make a contribution equal to 1% of eligible base salary for salaried employees with a service date 
on or after January 1, 1993 to cover certain benefits in retirement that are different from salaried employees with a service 
date prior to January 1, 1993. In addition, for salaried employees with a service date on or after January 1, 2001, the 
Company is required to contribute to its defined contribution retirement savings plan an amount equal to 4% of eligible 
base salary under the program. The charge to expense for the salaried defined contribution retirement savings plan was 
$6 million for each of the years ended December 31, 2017, 2016 and 2015.

The Company is also responsible for OPEB costs (medical, dental, vision, and life insurance) for hourly employees 
hired prior to May 19, 2008. Post-retirement benefit costs consist of service cost and interest cost on accrued obligations. 
Actuarial gains and losses on liabilities and any prior service costs are charged (or credited) to income over the average 
remaining service lives of employees. The benefit cost components shown in the Consolidated Statements of 
Comprehensive Income are based upon certain data specific to the Company, actuarial assumptions that were used for 
OPEB accounting disclosures, and certain allocation methodologies such as population demographics. The plan is 
unfunded and any future payments will be funded by the Company’s operating cash flows. As of December 31, 2017 and 
2016, the Company had an estimated OPEB liability for hourly employees hired prior to May 19, 2008, excluding those 
employees eligible to retire at the time of the sale of the Company, of $102 million and $144 million, respectively. 

As part of the Affordable Care Act enacted in 2010, the Company has evaluated the impact on “High-cost Health 
Plans” in which employers offering health plan coverage exceeding certain thresholds must pay an excise tax equal to 
40% of the value of the plan that exceeds the threshold amount. As a result of the excise tax, the Company has recorded 
$2 million in its OPEB liability as of both December 31, 2017 and 2016 with a corresponding adjustment to AOCL, net of 
tax. 

The Company provides contributions to certain international benefit plans; however, these contributions are not 

material for the periods presented. 

For all pension and OPEB plans in which employees participate, costs are determined within the FASB’s 

authoritative accounting guidance set forth on employers’ defined benefit pensions including accounting for settlements 
and curtailments of defined benefit pension plans, termination of benefits and accounting for post-retirement benefits other 
than pensions. In accordance with the authoritative accounting guidance, the Company recognizes the funded status of its 
defined benefit pension plans and OPEB plan in its Consolidated Balance Sheets with a corresponding adjustment to 
AOCL, net of tax.

retirement benefit plans is as follows (dollars in millions):

The Company’s pension and OPEB costs are calculated using various actuarial assumptions and methodologies as 

prescribed by authoritative accounting guidance. These assumptions include discount rates, expected return on plan 
assets, health care cost trend rates, inflation, rate of compensation increases, mortality rates and other factors. The 
Company reviews all actuarial assumptions on an annual basis.  

The discount rate is used to determine the present value of the Company’s benefit obligations. The Company’s 
discount rate is determined by matching the plans’ projected cash flows to a yield curve based on long-term, fixed income 
debt instruments available as of the measurement date of December 31, 2017.  

The overall expected rate of return on plan assets is based upon historical and expected future returns consistent 

with the expected benefit duration of the plan for each asset group adjusted for investment and administrative fees.  

 Health care cost trends are used to project future post-retirement benefits payable from the Company’s plans. For 

the Company’s December 31, 2017 obligations, future post-retirement medical care costs and prescription drug costs 
were forecasted assuming an initial annual increase of 5.20%, decreasing to 4.50% by the year 2036.  

As health care costs trends have a significant effect on the amounts reported, an increase and decrease of one-

percentage-point would have the following effects in the year ended December 31, 2017 (dollars in millions):

The Company’s investment strategy with respect to pension plan assets is to invest the assets in accordance with 

laws and regulations. The long-term primary objectives for the Company’s pension assets are to provide results that meet 
or exceed the plans’ actuarially assumed long-term rate of return without subjecting the funds to undue risk. To achieve 
these objectives the Company has established the following targets:

Expected benefit payments for pension and post-retirement benefits will be paid from plan trusts or corporate assets. 

The Company’s funding policy is to contribute amounts annually that are at least equal to the amounts required by 
applicable laws and regulations or to directly fund payments to plan participants. Additional discretionary contributions will 
be made when deemed appropriate to meet the Company’s long-term obligation to the plans.  

In June 2012, the Company established a non-qualified deferred compensation plan (“Deferred Compensation 

Plan”) for a select group of management. Under the terms of the plan, the Company has utilized a rabbi trust to 
accumulate assets to fund its promise to pay benefits under the Deferred Compensation Plan. The rabbi trust is an 
irrevocable trust, which restricts any use of funds (operational or otherwise) by the Company other than to pay benefits 
under the Deferred Compensation Plan, and prevents immediate taxation of contributed amounts. Funds are accumulated 
through both employee deferrals and a company match. Funds can be invested by the employee into a diversified group 
of investment options, which have been selected by the Company’s investment committee, that are all categorized as 
Level 1 in the fair value hierarchy. The company match resulted in a charge of zero to the Consolidated Statements of 
Comprehensive Income for each of the years ended December 31, 2017, 2016 and 2015, and the fair value of the rabbi 
trust plan assets and deferred compensation obligation was $8 million and $5 million as of December 31, 2017 and 2016, 
respectively.

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Act”) was enacted into law. The Tax Act makes broad and 

complex changes to the U.S. tax code that impact the Company, most notably a reduction of the U.S. corporate income 
tax rate from 35% to 21% for tax years beginning after December 31, 2017. The Tax Act also makes other changes 
including, but not limited to, the acceleration of depreciation for certain assets placed into service after September 27, 
2017 as well as a one-time deemed repatriation tax on undistributed foreign earnings and profits. Beginning in 2018, the 
Tax Act makes other changes impacting the Company such as additional limitations on executive compensation, the 
repeal of the domestic manufacturing deduction and qualifications around certain research and development 
expenditures. 

On December 22, 2017, the United States Securities and Exchange Commission (“SEC”) issued Staff Accounting 

Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. The Company 
recognized the income tax effects of the Tax Act for the year ended December 31, 2017, the reporting period in which the 
Tax Act was signed into law, in accordance with SAB 118. As such, the Company’s financial results reflect the income tax 
effects of the Tax Act and provisional amounts for those specific income tax effects of the Tax Act that could be 
reasonably estimated. 

In accordance with SAB 118, the Company recorded a $157 million deferred tax benefit related to the re-

measurement of certain deferred tax assets and liabilities and $5 million of tax expense recorded in connection with the 
transition tax on the mandatory deemed repatriation of foreign earnings and profits for the year ended December 31, 
2017.

The effective tax rate for the year ended December 31, 2017 was 4%, as compared with 37% in 2017. The lower 
rate is principally due to $155 million of tax benefit recorded in connection with the Tax Act, largely due to the $157 million 
decrease in net deferred tax liabilities to reflect the decrease in the corporate income tax rate from 35% to 21%. 

Deferred income tax assets and liabilities as of December 31, 2017 and 2016 reflect the effect of temporary 

differences between amounts of assets, liabilities and equity for financial reporting purposes and the bases of such 
assets, liabilities and equity as measured by tax laws, as well as tax loss and tax credit carry forwards. Net deferred tax 
assets and liabilities are classified as non-current in the consolidated statements of financial position. As described above, 
the deferred tax assets and liabilities are measured based on the enacted tax rates that will apply in the years in which the 
temporary differences are expected to be recovered or paid. As such, the Company re-measured its deferred tax assets 
and liabilities as a direct result of the enactment of the Tax Act. The primary impact of the re-measurement was a 
reduction in deferred tax assets and liabilities in connection with the reduction of the U.S. corporate income tax rate from 
35% to 21%. 

As of December 31, 2017, the Company had approximately $62 million of undistributed earnings in foreign 
subsidiaries which were subject to the one-time repatriation tax on foreign earnings required by the Tax Act. As a result, 
the Company recorded a charge of $5 million for the one-time repatriation tax, to be paid to the U.S. Government over the 
next eight years. The Company has not recognized any deferred tax liabilities associated with earnings in foreign 
subsidiaries, except for its subsidiaries located in China and Hong Kong, as they are intended to be permanently 
reinvested and used to support foreign operations. The deferred tax liabilities, if recorded, related to unremitted earnings 
that are indefinitely reinvested are not material. The Company has recorded a deferred tax liability of $2 million for the tax 
liability associated with the remittance of previously taxed income and unremitted earnings for its subsidiaries located in 
China and Hong Kong, which in previous periods had been considered indefinitely reinvested.

The estimated net operating loss carryforwards as of December 31, 2017 relate solely to U.S. state net operating 

loss carryforwards. Substantially all state operating loss carryforwards will not expire until 2027-2032. 

Management has determined, based on an evaluation of available objective and subjective evidence, that it is more 

likely than not that certain foreign deferred tax assets and an anticipated capital loss carryforward will not be realized; 
therefore these deferred tax assets are offset with a valuation allowance of $9 million and $5 million as of December 31, 
2017 and 2016, respectively. 

In accordance with the FASB’s authoritative accounting guidance on accounting for income taxes, the Company 
records uncertain tax positions on the basis of a two-step process whereby (1) it is determined whether it is more likely 
than not that the tax position will be sustained based on the technical merits of the position and (2) for those tax positions 
that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater 
than 50% likely to be realized upon ultimate settlement with the related tax authority. Based upon this process, the 
Company has recognized a liability for uncertain tax benefits as of December 31, 2017 and 2016.  Management does not 
anticipate any material changes in the balance within the coming year. The change in the liability for unrecognized tax 
benefits are as follows (dollars in millions): 

December 31, 2015................................................................................................  
Increases in unrecognized tax benefits as a result of current year activity ...........  
December 31, 2016................................................................................................

For the years ended December 31, 2017, 2016 and 2015, the Company recognized no interest and penalties in the 

Consolidated Statements of Comprehensive Income because either no uncertain tax positions were identified or the 
penalties and interest anticipated were not material in all the periods presented. The Company follows a policy of 
recording any interest or penalties in Income tax expense. 

Management does not anticipate any significant changes in unrecognized tax benefits within the coming year. There 

was $2 million as of both December 31, 2017 and 2016 of unrecognized tax benefits that, if recognized, would affect the 
annual effective tax rate. All of the Company's returns, once filed, will remain subject to examination by the various taxing 
authorities for the duration of the applicable statute of limitations (generally three years from the earlier of the date of filing 
or the due date of the return).

Environmental Matters 

The Company has an agreement with the Environmental Protection Agency to perform remedial activities at the 

Company’s Indianapolis, Indiana manufacturing facilities related to historical soil and groundwater contamination. As of 
December 31, 2017, the Company had a liability recorded in the amount of $13 million. 

Claims, Disputes, and Litigation  

The Company is party to various legal actions and administrative proceedings and subject to various claims arising 

in the ordinary course of business. These proceedings primarily involve commercial claims, product liability claims, 
personal injury claims and workers’ compensation claims. The Company believes that the ultimate liability, if any, in 
excess of amounts already provided for in the consolidated financial statements or covered by insurance on the 
disposition of these matters will not have a material adverse effect on the financial position, results of operations or cash 
flows of the Company.  

NOTE 17.    CONCENTRATION OF RISK  

As of December 31, 2017 and 2016, the Company employed approximately 2,700 employees with 89% of those 

employees in the U.S. Approximately 59% and 58% of the Company’s U.S. employees were represented by unions and 
subject to a collective bargaining agreement as of December 31, 2017 and 2016, respectively. In addition, many of the 
hourly employees outside the U.S. are represented by various unions. The Company is currently operating under a 
collective bargaining agreement with UAW Local 933 that expires in November 2023.

NOTE 18.    CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS  

Senior Notes Held by Executive Officers 

In May 2015, the Company redeemed $100,000 and $450,000 of ATI’s 7.125% Senior Notes held by Lawrence E. 

Dewey, Chairman and Chief Executive Officer, and David S. Graziosi, President and Chief Financial Officer, respectively, 
at the specified redemption price in the governing indenture equal to 103.563% of the principal amount plus any accrued 
and unpaid interest. 

Repurchase of Common Stock held by ValueAct Capital Master Fund 

On February 3, 2017, the Company entered into a stock repurchase agreement with ValueAct Capital Master Fund, 

L.P., a related party, to repurchase 10,525,204 shares of the Company’s common stock for approximately $363 million. 
The shares were repurchased under the stock repurchase program approved by the Board of Directors in November 
2016. The purchase closed on February 8, 2017 and was funded with cash on hand and borrowings under the Revolving 
Credit Facility. The shares were subsequently retired. 

Sales to Customer Indirectly Owned by Director 

During 2017, the Company had net sales of less than $30 million to Gillig LLC (“Gillig”) and less than $6 million to 
General Dynamics Corporation (“GD”). James A. Star, a member of the Company’s Board of Directors, has an indirect 
material interest in Gillig as a result of trusts for the benefit of his wife and children collectively owning an approximately 
5% interest in the entities that directly and indirectly own Gillig LLC. In addition, all of the remaining direct and indirect 
interests in Gillig LLC are owned by trusts for the benefit of members of Mr. Star’s wife’s immediate and extended family.  
Mr. Star also has an indirect material interest in GD as a result of trusts for the benefit of his wife, children and members 
of his wife’s family collectively owning approximately 10% of the outstanding shares of common stock of GD.  

NOTE 19.     COMMON STOCK 

On November 14, 2016, the Company’s Board of Directors authorized the Company to repurchase up to $1,000 
million of its common stock pursuant to a stock repurchase program (“2016 Repurchase Program”). On November 8, 
2017, the Company’s Board of Directors increased the authorization by $500 million bringing the total amount authorized 
under the 2016 Repurchase Program to $1,500 million. The terms of the 2016 Repurchase Program provide that the 
Company may repurchase shares of our common stock, from time to time depending on market conditions and corporate 
needs, in the open market or through privately negotiated transactions in accordance with Rule 10b-18 of the Exchange 
Act. Unless earlier terminated by our Board of Directors, the 2016 Repurchase Program will expire on December 31, 
2019. 

During 2017, the Company purchased approximately $885 million of its common stock under the 2016 Repurchase 

Program. All transactions during 2017 were settled in cash during the same period.

NOTE 20.    EARNINGS PER SHARE  

The Company presents both basic and diluted earnings per share (“EPS”) amounts. Basic EPS is calculated by 

dividing net income by the weighted average number of common shares outstanding during the reporting period. Diluted 
EPS is calculated by dividing net income by the weighted average number of common shares and common equivalent 
shares outstanding during the reporting period that are calculated using the treasury stock method for stock-based 
awards. The treasury stock method assumes that the Company uses the proceeds from the exercise of awards to 
repurchase common stock at the average market price during the period. The assumed proceeds under the treasury stock 
method include the purchase price that the grantee will pay in the future and compensation cost for future service that the 
Company has not yet recognized. As of December 31, 2017, 2016, and 2015, the Company had 0.2 million, 0.2 million, 
and 0.7 million outstanding stock options that were not included in the diluted EPS calculation because they were anti-
dilutive. Basic and diluted EPS for the full-year is calculated using the weighted average shares of common stock 
outstanding during the year while quarterly basic and diluted EPS is calculated using the weighted average shares of 
common stock outstanding during the quarter; therefore, the sum of the four quarters’ EPS may not equal full-year EPS. 

The following table reconciles the numerators and denominators used to calculate basic EPS and diluted EPS (in 

millions, except per share data):

Schedule I—Parent Company only Footnote 

NOTE 1—BASIS OF PRESENTATION  

Allison Transmission Holdings, Inc. (the “Parent Company”) is a holding company that conducts all of its business 

operations through its subsidiaries. There are restrictions on the Parent Company’s ability to obtain funds from its 
subsidiaries through dividends (refer to NOTE 7 “Debt” of the Consolidated Financial Statements). The entire amount of 
our consolidated net assets was subject to restrictions on payment of dividends at the end of December 31, 2017, 2016 
and 2015. Accordingly, these financial statements have been presented on a “parent-only” basis. Under a parent-only 
presentation, the Parent Company’s investments in its consolidated subsidiaries are presented under the equity method of 
accounting. These parent-only financial statements should be read in conjunction with Allison Transmission Holdings, 
Inc.’s audited Consolidated Financial Statements included elsewhere herein.

ITEM 9.   Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

None. 

ITEM 9A. Controls and Procedures 

Evaluation of Disclosure Controls and Procedures  

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the 
effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange 
Act), as of December 31, 2017. In designing and evaluating the disclosure controls and procedures, management 
recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable 
assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must 
reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the 
benefits of possible controls and procedures relative to their costs.  

Based on the evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure 

controls and procedures as of December 31, 2017, the end of the period covered by this Annual Report on Form 10-K, 
were effective to provide reasonable assurance that information we are required to disclose in reports that we file or 
submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the 
Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to 
our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely 
decisions regarding required disclosure.  

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 Exchange Act). Our 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 generally accepted accounting principles.  

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.  

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief 

Financial Officer, we conducted an assessment of the effectiveness of our internal control over financial reporting as of 
December 31, 2017. In making this assessment, our management used the criteria set forth by the Committee of 
Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based on this 
assessment, management concluded that our internal control over financial reporting was effective as of December 31, 
2017. PricewaterhouseCoopers LLP, our independent registered public accounting firm, has audited the effectiveness of 
our internal control over financial reporting as of December 31, 2017. Their report is included in Part II, Item 8, “Financial 
Statements and Supplementary Data” in this Annual Report on Form 10-K.

under the Exchange Act) during the quarter ended December 31, 2017 that have materially affected, or are reasonably 
likely to materially affect, our internal control over financial reporting.
