Item 1.  Business. 

Overview of Our Business 

PART I 

Axcelis Technologies, Inc. (“Axcelis,” the “Company,” “we,” “us,” or “our”) designs, manufactures and 
services ion implantation and other processing equipment used in the fabrication of semiconductor chips. We believe that 
our Purion family of products are the most innovative implanters available on the market today. We sell to leading 
semiconductor chip manufacturers worldwide. The ion implantation business represents 93.2% of our revenue in 2016 
with the remaining 6.8% of revenue derived from other legacy processing systems. In addition to equipment, we provide 
extensive aftermarket lifecycle products and services, including used tools, spare parts, equipment upgrades, 
maintenance services and customer training. 

Axcelis’ business commenced in 1978 and its current corporate entity was incorporated in Delaware in 1995, 
and is headquartered in Beverly, Massachusetts. We maintain an internet site at www.axcelis.com. On or through our 
website, investors may access, free of charge, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current 
reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the 
Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the 
Securities and Exchange Commission. Our website and the information contained therein or connected thereto shall not 
be deemed to be incorporated into this Form 10-K. 

2016 was a challenging year for the Company. Our 2016 revenues of $267.0 million were below our 2015 

revenues due to lower purchasing from key memory customers, particularly in dynamic random-access memory 
(“DRAM”). Despite this, Axcelis made progress towards our long-term strategic goal of regaining a position of market 
share leadership in the ion implant semiconductor equipment market. 

In 2016 we continued to invest a significant portion of our resources in research and development programs 

related to our Purion ion implantation platform.  During the year, our customer base for Purion ion implanters expanded 
significantly, and we successfully introduced several new extensions to our core Purion systems, such as the hot silicon 
carbide Purion M, the Purion EXE and Purion VXE. We placed Purion ion implanters with seven new customers, as well 
as within seven new fabs owned by existing customers.  We expect customer adoption and demand for our Purion 
products to continue to grow. 

In addition, we continued to improve our gross margin performance in 2016. The Company’s gross margins for 

2016 were 37.3%, up from 33.7% in 2015. We also worked hard to ensure that manufacturing and operating expense 
levels remain well aligned to business conditions. We believe that the most fundamental interest of our stockholders is in 
consistent, profitable, financial performance and we expect to deliver such results in 2017. Our performance is subject to 
risks and uncertainties discussed below under Item 1A Risk Factors. 

Industry Overview 

Semiconductor chips, also known as integrated circuits, are used in a continuously evolving range of consumer 
and industrial products, including for example, personal computers, mobile devices, automobiles, sensors and controllers 
for the “internet of things,” and data storage servers. Types of semiconductor chips include DRAM and “negative and” 
(“NAND”) Flash memory; logic devices to process information; and “system on chip” devices (which have both logic 
and memory features). The semiconductor chip manufacturers industry is entering a period of sustained growth driven by 
the increased number of devices providing information to, and receiving information from, the internet. This 
development, sometimes referred to as the “Connected World,” is increasing demand for chips used in data input, such as 
image sensors, which are often manufactured using mature processing technologies, as well as for memory chips to 
support the storage of data, internet streaming and “cloud computing” data analytics. 

Most semiconductor chips are built on a wafer of silicon of either 200mm (8 inches) or 300mm (12 inches) in 

diameter. Each semiconductor chip is made up of millions of tiny transistors or “switches” to control the functions of the 

2 

 
 
 
 
 
  
 
 
 
 
device. Transistors are created in the silicon wafer by introducing various precisely placed impurities into the silicon in 
specific patterns.  

Semiconductor chip manufacturers own or manage wafer fabrication facilities (often referred to as a “fab”), 
which utilize many different types of equipment in the making of integrated circuits. Over 300 process steps utilizing 
over 50 different types of process tools are required to make a single device like a microprocessor. Semiconductor chip 
manufacturers seek device performance benefits through new products and technology enhancements and productivity 
improvements through increased throughput, equipment utilization and higher manufacturing yields. Capacity is added 
by increasing the amount of manufacturing equipment in existing fabrication facilities and by constructing new 
fabrication facilities.  

We have different types of customers, which impacts timing of purchases and technology requirements. Some 
customers are integrated electronics manufacturers, who make semiconductor chips for their own devices.  These same 
companies may also act as foundries, who manufacture chips for other electronic manufacturers or chip design 
companies.  Some customers only function as foundries.  A few companies design and manufacture branded chips that 
are sold to device manufacturers.  In addition, some customers may have partnerships or joint ventures with two or more 
semiconductor chip manufacturers to share the technology development and capital investment.  The timing of purchases 
by foundry customers will depend on their receipt or loss of manufacturing contracts.  Also, foundry customers will look 
for equipment that can deliver the broadest capabilities so that they are prepared to manufacture all chip types, while 
integrated electronics manufacturers may invest in processing equipment that is dedicated to a specific application they 
require for their products. 

The semiconductor capital equipment industry is highly cyclical, as global chip production capacities 

successively exceed, then lag behind, global chip demand. When chip demand is high, and inventories low, chip 
manufacturers add capacity through capital equipment purchases. Given the difficulties of forecasting and calibrating 
chip demand and production capacity, the industry periodically experiences excess chip inventories and softening chip 
prices. Device manufacturers react with muted capital spending, lowering the demand for capital equipment. Changes in 
consumer and business demand for products in which chips are used also affect the industry. A successful semiconductor 
capital equipment manufacturer must not only provide some of the most technically complex products manufactured in 
the world but also must manage its business to thrive during the inevitable low points in the cycle. 

Axcelis’ Strategy 

Axcelis’ 2017 strategic initiatives are: 

•  Drive top line and market share growth with Purion systems, capitalizing on investments by customers in 

the memory and the mature technology sectors 

• 

• 

Increase aftermarket revenues by delivering differentiated high value products in each business segment, 
including upgrades, spares, consumables, service and used tools 

Improve gross margins 

•  Enhance profitability and cash generation 

We have continued to invest in research and development through the industry cycles to ensure our products 
meet the needs of our customers. We take pride in our scientists and engineers who continue to add to our portfolio of 
patents and unpatented proprietary technology to ensure that our investment in technology leadership is translated into 
unique product advantages. We strive for operational excellence by focusing on ways to lower our product, 
manufacturing and design costs and to improve our delivery times to our customers. We will continue to use our Global 
Customer Teams and a focused account management structure to maintain and strengthen our customer relationships and 
increase customer satisfaction. Finally, we will maintain a strong cash balance to ensure that we have enough capital to 
fund a potential ramp up in our business.

Ion Implantation Systems 

Ion implantation is a principal step in the transistor formation cycle of the semiconductor chip manufacturing 

process. Ion implantation is also used to change the characteristics of the silicon for reasons other than transistor 
formation, a process known as “material modification”. An ion implanter is a large, technically advanced system that 
injects dopants such as arsenic, boron or phosphorus into a wafer. These dopants are ionized and therefore have electric 
charges. This electric charge allows the dopants to be manipulated, moved and accelerated with electric and magnetic 
fields. Ion implanters use these fields to create a beam of ions with a precisely defined amount of energy (ranging 
between several hundred and three million electron-volts) and with a precisely defined amount of beam current (ranging 
from microamps to milliamps). Certain areas of the silicon wafer are blocked off by a polymer material known as 
photoresist, which acts as a “stencil” to pattern devices so that the dopants will only enter the wafer where needed. 
Typical process flows require twenty implant steps, with the most advanced processes requiring thirty or more. Each 
implant step is characterized by four key parameters: dopant type, dose (amount of dopant), energy (depth into the 
silicon) and tilt (angle of wafer relative to the ion beam). 

In order to cover the wide range of implant steps, three different types of implanters have been developed, each 
designed to cover a specific range of applications, primarily defined by dose and energy. The three traditional implanter 
types are referred to as medium current, high current and high energy: 

•  Medium current implanters are the original model of ion implanter, with mid to low-range energy and dose 

capability. 

•  High current implanters were the second type of implanter to emerge, having low energy capability and 

high dose range. 

•  High energy implanters emerged to address the need for deeper implants with a high energy range and low 

dose. 

The Purion Platform and Family of Ion Implanters 

Axcelis offers a complete line of high energy, high current and medium current implanters for all application 

requirements. Our flagship systems are all based on a common Purion platform which offers purity, precision and 
productivity by combining a high-speed, state-of-the-art single wafer end station, enabling unmatched throughput (500 
wafers per hour), and an advanced spot beam that ensures that all points across the wafer see the same beam at the same 
beam angle, resulting in exceptional process control and maximum yield. 

•  High Energy Implant.  Our Purion XE high energy system combines Axcelis’ production-proven RF 
Linac high energy, spot beam technology with the Purion platform. Axcelis is a market leader in high 
energy ion implanters, and we expect to maintain our leadership in the high energy segment through sales 
of both our multi-wafer legacy high energy systems and the Purion XE, the Purion EXE and the Purion 
VXE.  

•  Medium Current Implant.  Our Purion M medium current system offers higher productivity and lower 
cost of ownership than competitive offerings, in addition to other advantages. Our Purion M systems also 
offer differentiation for specialty applications, like hot silicon carbide. 

•  High Current Implant.  Our Purion H high current system fulfills all traditional high current requirements 
while extending beyond traditional high current energy and dose ranges. In order to maximize utilization 
and flexibility, the Purion H can process some traditional mid-current implants. In addition, the Purion H is 
extendable into ultra-low energy applications to satisfy future process requirements, including leakage 
current performance. The Purion H also provides advantages for material modification applications, 
including hot and cold implant. 

4 

 
 
 
 
 
 
 
 
 
 
 
 
We believe our ion implant products will continue to meet customer demand for advantages in productivity, 

process performance and technical extendibility.  

Dry Strip 

Axcelis previously manufactured other types of semiconductor processing equipment in addition to the ion 

implanters, including dry strip wafer cleaning systems. In December 2012, we sold the intellectual property rights 
relating to our dry strip business to Lam Research Corporation (“Lam”). Under the agreements with Lam, Axcelis may 
continue to sell dry strip systems for 200mm and 150mm wafers through December 2017. We will continue to service 
and support our dry strip installed base indefinitely. 

Aftermarket Support and Services 

Through our Customer Innovation and Support business, we offer our customers extensive aftermarket service 

and support throughout the lifecycle of the equipment we manufacture as well as equipment we previously 
manufactured. We believe that approximately 3,000 of our products are in use in 32 countries worldwide. The service 
and support that we provide includes used tools, spare parts, equipment upgrades, and maintenance services. We provide 
varying levels of sales, service and applications support out of our field offices to customers located in 32 countries. 
Revenue generated through our service and support business represented 47.8%, 43.0% and 59.8% of revenue in 2016, 
2015 and 2014, respectively. 

To support our aftermarket business, we have approximately 200 staff members, including sales and marketing 

personnel, field service engineers, and spare parts and applications engineers, as well as employees located at our 
manufacturing facilities who work with our customers to provide customer training and documentation, product, process 
and applications support.  

Most of our customers maintain spare parts inventories for our machines. In addition to our web-based spare 
parts management and replenishment tracking program, we offer a number of Business-to-Business options to support 
our customers’ parts management requirements. Our Axcelis Managed Inventory service offering, a parts consignment 
arrangement, provides the customer with full spares support, with Axcelis retaining responsibility for the complete 
supply chain. The expansion of these services provides ease of use alternatives that help us reduce order fulfillment costs 
and improve cycle time, resulting in an expanded customer base for this service offering. 

Sales and Marketing 

We primarily sell our equipment and services through our direct sales force. We conduct sales and marketing 
activities from our sales offices located in the United States, Taiwan, South Korea, China, Germany, Singapore, Japan 
and Italy. 

International revenue, including export sales from our U.S. manufacturing facilities to foreign customers and 
sales by foreign subsidiaries and branches, accounted for 80.0%, 85.1% and 80.0% of total revenue in 2016, 2015 and 
2014, respectively. Substantially all of our sales are denominated in U.S. dollars. See Note 18 to our Consolidated 
Financial Statements contained in Item 15 of this Form 10-K for a breakdown of our revenue and long-lived assets in the 
United States, Europe and Asia. See also Item 1A, “Risk Factors,” for information about risks attendant to our foreign 
operations. 

Customers 

In 2016, the top 20 semiconductor chip manufacturers accounted for approximately 87.2% of total 

semiconductor capital equipment spending, down slightly from 87.7% in 2015. These manufacturers are from the largest 
semiconductor chip manufacturing regions in the world: the United States, Asia Pacific (Taiwan, South Korea, Singapore 
and China), Japan and Europe.  

5 

 
 
 
 
 
 
 
 
 
 
 
 
Revenue from our ten largest customers accounted for 70.2%, 76.8% and 68.1%, of revenue in 2016, 2015 and 
2014, respectively. We expect that sales of our products to relatively few customers will continue to account for a high 
percentage of revenue for the foreseeable future. In 2016, one customer accounted for 17.0% of revenue. In 2015, two 
customers accounted for 29.3% and 10.5% of revenue, respectively. In 2014, two customers accounted for 17.4% and 
12.3% of revenue, respectively. 

Our Beverly, Massachusetts Advanced Technology Center houses a process development laboratory with 

12,500 sq. ft. of class 10/100/1000 clean room for product demonstrations and process development and a 34,000 sq. ft. 
customer training center. The Advanced Technology Center provides infrastructure and process capabilities that allow 
customers to test their unique process steps on our systems under conditions that substantially replicate the customers’ 
production environment. This facility also provides significant capability for our research and development efforts. 

Research and Development 

Our industry continues to experience rapid technological change, requiring us to frequently introduce new 
products and enhancements. Our ability to remain competitive in this market will depend in part upon our ability to 
develop new and enhanced systems and to introduce these systems at competitive prices on a timely and cost effective 
basis. 

We devote a significant portion of our personnel and financial resources to research and development programs 

and seek to maintain close relationships with our customers to remain responsive to their product needs. We have also 
sought to reduce the development cycle for new products through a collaborative process whereby our engineering, 
manufacturing and marketing personnel work closely together with one another and with our customers at an earlier 
stage in the process. We use 3D, computer-aided design, finite element analysis and other computer-based modeling 
methods to test new designs. 

Our expenses for research and development were $34.4 million, $32.6 million and $33.5 million in 2016, 2015 
and 2014, respectively, or 12.9%, 10.8% and 16.5% of revenue, respectively. We expect that research and development 
expenditures will continue to represent a similar level of investment in future years. 

Manufacturing 

We manufacture products at our 417,000 sq. ft. ISO 9001:2008, ISO 14001:2004 certified plant in Beverly, 
Massachusetts. Our facility employs best in class manufacturing techniques, including lean manufacturing, six sigma 
controls and advanced inventory management, purchasing and quality systems. 

Our clean manufacturing process uses class 1,000/10,000 space to facilitate most of our manufacturing 

requirements. 

The Company’s core manufacturing and supply chain competency is built around system assembly and testing, 

which remains an in-house capability due to the high degree of expertise and intellectual property associated with the 
process and design. Non-core work is sourced to one of several global partners and includes items such as vacuum 
systems, wafer handling and commodity-level components. We continuously pursue outsourcing opportunities where the 
economics are justified, with a goal of enabling quality and margin improvement. Our supply chain team is globally 
focused and is located in Beverly and Singapore. Customized and commercially available software solutions drive our 
planning, purchasing and inventory tracking process. 

Our products are designed to be assembled and tested in a modular fashion, which facilitates our 

industry-recognized “ship-from-cell” process. Specially developed test stands, software and tooling provide the 
framework for this accelerated delivery process. Customers that choose ship-from-cell substantially improve their 
delivery times while receiving the same high level of quality provided by more traditional longer cycle integration 
techniques. Product margins and inventory turns also improve as a result of shorter factory cycle times and increased 
labor productivity. 

6 

 
 
 
 
 
 
 
 
 
 
 
Installation of our equipment is provided by factory and field teams. The process includes assembling the 

equipment at its installation site and after it has been connected, recalibrating it to factory specifications. 

Competition 

The semiconductor chip manufacturer industry is highly competitive and is characterized by a small number of 
participants ranging in size. Significant competitive factors in the semiconductor capital equipment market include price, 
cost of ownership, equipment performance, customer support, capabilities and breadth of product line. 

In ion implantation, we mainly compete against Applied Materials, Inc. We and Applied Materials are the only 

ion implant manufacturers with a full range of implant products, and service and support infrastructures able to service 
our customers globally. Three other niche players we compete with from time to time include Advanced Ion Beam 
Technology, Inc., Nissin Ion Implantation Co., Ltd. and SEN Corporation. 

Intellectual Property 

We rely on patent, copyright, trademark and trade secret protection in the United States and in other countries, 
as well as contractual restrictions, to protect our proprietary rights in our products and our business. As of December 31, 
2016, we had 314 active patents issued in the United States and 465 active patents granted in other countries, as well as 
191 patent applications (44 in the United States and 147 in other countries) on file with various patent agencies 
worldwide. Patents are generally in effect for up to 20 years from the filing of the application. 

We intend to file additional patent applications and grow our intellectual property portfolio as appropriate. 
Although patents are important to our business, we do not believe that we are substantially dependent on any single 
patent or any group of patents. 

We have trademarks, both registered and unregistered, that are maintained to provide customer recognition for 
our products in the marketplace. Trademark registrations generally remain in effect as long as the trademarks are in use. 
From time to time, we enter into license agreements with third parties under which we obtain or grant rights to patented 
or proprietary technology. We do not believe that any of our licenses are currently material to us.  

Backlog 

Systems backlog, including deferred systems revenue, was $17.5 million and $22.5 million as of December 31, 
2016 and 2015, respectively. We believe it is meaningful to investors to include deferred systems revenue as part of our 
backlog. Deferred systems revenue represents revenue that will be recognized in future periods based on prior shipments. 
Our policy is to include in backlog only those system orders for which we have accepted purchase orders and are 
typically due to ship within six months. All orders are subject to cancellations or rescheduling by customers with limited 
or no penalties. 

Backlog does not include orders received and fulfilled within a quarter. Our backlog at the beginning of a 
quarter typically does not include all orders required to achieve our sales objectives for that quarter. Backlog is not 
necessarily an indicator of future business trends because orders for services or parts received during the quarter are 
generally performed or shipped within the same quarter. 

Bookings in the quarter ended December 31, 2016 were $34.8 million compared to $26.1 million in the quarter 

ended December 31, 2015. 

Employees 

As of December 31, 2016, we had 814 employees and 31 temporary staff worldwide, of which 603 work in 

North America, 190 in Asia and 52 in Europe. We consider our relationship with our employees to be good. Our 
employees are not represented by a labor union and are not subject to a collective bargaining agreement. One of our 
European locations has formed a work council, which has certain information and discussion rights under applicable law. 

7 

 
 
 
 
 
 
 
 
 
 
 
 
 
Environmental 

We are subject to environmental laws and regulations in the countries in which we operate that regulate, among 

other things: air emissions; water discharges; and the generation, use, storage, transportation, handling and disposal of 
solid and hazardous wastes produced by our manufacturing, research and development and sales activities. As with other 
companies engaged in like businesses, the nature of our operations exposes us to the risk of environmental liabilities, 
claims, penalties and orders. 

We are proud of our commitment to improving our environment. We believe that our operations are in 
substantial compliance with applicable environmental laws and regulations and that there are no pending environmental 
matters that would have a material impact on our business. We are ISO-14001 certified at our Beverly, MA facility.

Item 1A.  Risk Factors. 

Risks Related to Our Business and Industry 

Set forth below and elsewhere in this Form 10-K and in other documents we file with the SEC are risks and 
uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking 
statements contained in this Form 10-K. We note that factors set forth below, individually or in the aggregate, may cause 
our actual results to differ materially from expected and historical results. We note these factors for investors as 
permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to 
predict or identify all such factors. Consequently, you should not consider the following to be a complete discussion of 
all potential risks or uncertainties. 

If semiconductor chip manufacturers do not make sufficient capital expenditures, our sales and profitability will be 
harmed. 

New systems orders and used tool sales depend upon demand from semiconductor chip manufacturers who 

build or expand fabrication facilities. The impact of this demand on the Company will vary with the type of 
semiconductor chip manufacturers who are purchasing systems.  For example, changes in demand in the memory and 
mature process technology segments will most significantly impact the Company since customers in these segments have 
established Axcelis ion implanters as process tools of record. When the rate of construction or expansion of fabrication 
facilities declines, demand for our systems will decline, reducing our revenue. In addition, all or a portion of the demand 
for increased capacity may be satisfied by a semiconductor chip manufacturer’s ability to reconfigure and re-use 
equipment they already own.  Revenue decline also hurts our profitability because our established cost structure and our 
continued investments in engineering, research and development and marketing necessary to develop new products and 
to maintain extensive customer service and support capabilities limit our ability to reduce expenses in proportion to 
declining sales.  

If we fail to develop and introduce reliable new or enhanced products and services that meet the needs of 
semiconductor chip manufacturers, our results will suffer. 

Rapid technological changes in semiconductor chip manufacturing processes require us to respond quickly to 
changing customer requirements. Our future success will depend in part upon our ability to develop, manufacture and 
successfully introduce new systems and product lines with improved capabilities and to continue to enhance existing 
products. This will depend upon a variety of factors, including new product selection, timely and efficient completion of 
product design and development as well as manufacturing and assembly processes, product performance in the field and 
effective sales and marketing. In particular: 

•  We must continue to develop competitive technical specifications of new systems, or enhancements to our 
existing systems, and manufacture and ship these systems or enhancements in volume in a timely manner. 

•  We will need to accurately predict the schedule on which our customers will be ready to transition to new 

products, in order to accurately forecast demand for new products while managing the transition from older 
products. 

•  We will need to effectively manage product reliability or quality problems that often exist with new 

systems, in order to avoid reduced orders, higher manufacturing costs, delays in acceptance and payment 
and additional service and warranty expenses. 

•  Our new products must be accepted in the marketplace. 

Our failure to meet any of these requirements will have a material adverse effect on our operating results and 

profitability. 

10 

 
 
 
 
 
 
 
 
 
 
 
 
A significant portion of our revenue depends on customers electing to buy aftermarket products and services from 
Axcelis. 

Historically, a significant portion of our product revenue and all of our service revenue relates to our sale of 

“aftermarket” products and services, which include parts, consumables, upgrades, service contracts, and time and 
materials billings. Some of our customers purchase fewer aftermarket products and services, often training their own 
staff to maintain and service semiconductor capital equipment rather than relying on the equipment manufacturer for 
these services. In addition, we compete against third party parts suppliers for the sale of parts and consumables that are 
not protected by patents or otherwise proprietary. To the extent our customers purchase parts and services from other 
vendors or provide their own system maintenance labor, our revenue will be less. 

Our financial results may fluctuate significantly. 

We derive our new systems revenue from the sale of a small number of expensive products to a relatively small 

number of customers. The list prices on our ion implant and other systems range from $0.6 million to $7.5 million. We 
also sell used equipment in our aftermarket business. At our current sales level, each sale, or failure to make a sale, has a 
significant effect on us in a particular quarter. In a given quarter, a number of factors can adversely affect our revenue 
and results, including changes in our product mix, increased fixed expenses per unit due to reductions in the number of 
products manufactured, and higher fixed costs due to increased levels of research and development and expansion of our 
worldwide sales and marketing organization. Our financial results also fluctuate based on gross profit realized on sales. 
A variety of factors may cause gross profit as a percentage of revenue to vary, including the mix and average selling 
prices of products sold, costs to manufacture and customize systems, warranty costs and impact of changes to inventory 
reserves. New product introductions may also affect our gross margins. Fluctuations in our financial results may have an 
adverse effect on the price of our common stock. 

Our financial results may fall short of anticipated levels because forecasting revenue and profitability is complex and 
may be inaccurate. 

Management may from time to time provide financial forecasts. These forecasts are based on assumptions, 

which are believed to be reasonable when made, of fab utilization, shipment timing and system acceptance timing. Any 
of these assumptions can prove erroneous and the level of revenue recognizable in a particular quarter may vary from the 
forecast. Our lengthy sales cycle, coupled with customers’ competing capital budget considerations, make the timing of 
customer orders difficult to predict. In addition, our backlog at the beginning of a quarter typically does not include all 
orders required to achieve our sales objectives for that quarter and is not a reliable indicator of our future sales. As a 
result, our revenue and operating results for a quarter depend on our shipping orders as scheduled during that quarter, 
receiving customer acceptance of previously shipped products, and obtaining new orders for products to be shipped in 
that same quarter. Any delay in, or cancellation of, scheduled shipments and customer acceptances or in shipments from 
new orders could materially affect our financial results. 

Accounting rules addressing revenue recognition add more complexity in forecasting quarterly revenue and 
profitability. Orders for our products usually contain multiple delivery elements that result in revenue deferral under 
generally accepted accounting principles. Due to the foregoing factors, investors should understand that our actual 
financial results for a quarter may vary significantly from our forecasts of financial performance for that quarter. Failure 
to meet forecasted financial performance may have an adverse effect on the price of our common stock. 

The semiconductor industry is highly cyclical and we expect that demand for our products will regularly increase and 
decrease, making it difficult to manage the business and potentially causing harm to our sales and profitability. 

The semiconductor business is highly cyclical, experiencing upturns when the demand for our products is high 

and downturns when our customers are not investing in new or expanded fabrication facilities. From time to time, 
inventory buildups in the semiconductor industry, resulting in part from periodic downturns, produce an oversupply of 
semiconductors. This can cause a reduced demand for capital equipment such as our products, negatively impacting our 
sales and level of profitability. Our revenue can vary significantly from one point in the cycle to another, making it 
difficult to manage the business, both when revenue is increasing and when it is decreasing. In addition, a substantial 

11 

 
 
 
 
 
 
 
 
portion of our operating expenses do not fluctuate with changes in volume. Significant decreases in revenue can therefore 
have a disproportionate effect on profitability. In addition, reduced demand for our products and services may require 
Axcelis to implement cost reduction efforts, including restructuring activities, which may adversely affect Axcelis’ 
ability to capitalize on opportunities that arise in the future due to our highly cyclical industry. 

If we fail to compete successfully in the highly competitive semiconductor capital equipment industry, our sales and 
profitability will decline. 

The ion implant segment is highly competitive and includes one company with substantially greater financial, 

engineering, manufacturing, marketing and customer service and support resources that may better position it to compete 
successfully, as well as several smaller companies that could provide innovative systems with technology that may have 
performance advantages. We expect our competitors to continue to improve the design and performance of their existing 
products and processes and to introduce new products and processes with improved price and performance 
characteristics. If we are unable to improve or introduce competing products when demanded by the markets, our 
business will be harmed. Finally, if we must lower prices to remain competitive without commensurate cost of goods 
savings, our gross margins and profitability will be adversely affected. 

We are dependent on sales to a limited number of large customers; the loss of a significant customer or any reduction 
in orders from them could materially affect our sales. 

Historically, we have sold a significant portion of our products and services to a limited number of fabricators 

of semiconductor products. For example, in 2016, our top ten customers accounted for 70.2% of our net sales, in 
comparison to 76.8% and 68.1% in 2015 and 2014, respectively. None of our customers has entered into a long-term 
agreement requiring it to purchase our products. Although the composition of the group comprising our largest customers 
has varied from year to year, the loss of a significant customer or any reduction or delays in orders from any significant 
customer will adversely affect us. The ongoing consolidation of semiconductor chip manufacturers may result in the loss 
of a customer. 

Axcelis is subject to the risks of operating internationally and we derive a substantial portion of our revenue from 
outside the United States, especially from Asia. 

We are substantially dependent on sales of our products and services to customers outside the United States. 

International sales, including export sales from our U.S. manufacturing facilities to non-U.S. customers and sales by our 
non-U.S. subsidiaries and branches, accounted for 80.0% of total revenue in 2016 in comparison to 84.8% of total 
revenue in 2015 and 80.0% in 2014. Ion implanter system shipments to Asian customers represented 75.3% of total 
shipment dollars in 2016 in comparison to 78.9% in 2015 and 78.3% in 2014. We anticipate that international sales will 
continue to account for a significant portion of our revenue. The potential increasing investment in semiconductor chip 
manufacturing capability in China is expected to create disruption in our markets, resulting in both risk and opportunity. 
Because of our dependence upon international sales, our results and prospects may be adversely affected by a number of 
factors, including: 

• 

• 

• 

• 

• 

• 

unexpected changes in laws or regulations resulting in more burdensome governmental controls, tariffs, 
restrictions, embargoes or export license requirements; 

volatility in currency exchange rates; 

political and economic instability; 

difficulties in accounts receivable collections; 

extended payment terms beyond those customarily offered in the United States; 

difficulties in managing suppliers, service providers or representatives outside the United States; 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

difficulties in staffing and managing foreign subsidiary and branch operations; and 

potential adverse tax consequences. 

We may not be able to maintain and expand our business if we are not able to hire, retain and integrate qualified 
personnel. 

Our business depends on our ability to attract and retain qualified, experienced employees. There is substantial 

competition for experienced engineering, technical, financial, sales and marketing personnel in our industry. In 
particular, we must attract and retain highly skilled design and process engineers. Competition for such personnel is 
intense, particularly in the Boston metropolitan area, as well as in other locations around the world. If we are unable to 
retain our existing key personnel, or attract and retain additional qualified personnel, we may from time to time 
experience insufficient levels of staffing to fully develop, manufacture and market our products and perform services for 
our customers. As a result, our growth could be limited or we could fail to meet our delivery commitments or experience 
deterioration in service levels or decreased customer satisfaction, all of which could adversely affect our financial results. 

Our dependence upon suppliers for many components and sub-assemblies could result in increased costs or delays in 
the manufacture and sale of our products. 

We rely to a substantial extent on outside vendors to manufacture many of the components and sub-assemblies 

of our products. We obtain many of these components and sub-assemblies from a limited group of suppliers. 
Accordingly, based on situations outside of our control, we may be unable to obtain an adequate supply of required 
components on a timely basis, on price and other terms acceptable to us, or at all. In addition, we often quote prices to 
our customers and accept customer orders for our products before purchasing components and sub-assemblies from our 
suppliers. If our suppliers increase the cost of components or sub-assemblies, we may not have alternative sources of 
supply and may not be able to raise the price of our products to cover all or part of the increased cost of components, 
negatively impacting our gross margins. 

The manufacture of some of these components and sub-assemblies is an extremely complex process and 
requires long lead times. As a result, we have in the past, and may in the future, experience delays or shortages. If we are 
unable to obtain adequate and timely deliveries of our required components or sub-assemblies, we may have to seek 
alternative sources of supply or manufacture these components internally. This could delay our ability to manufacture or 
to ship our systems on a timely basis, causing us to lose sales, incur additional costs, delay new product introductions and 
suffer harm to our reputation. 

Moreover, if actual demand for Axcelis’ products is different than expected, Axcelis may purchase more or 

fewer parts than necessary or incur costs for canceling, postponing or expediting delivery of parts. If Axcelis purchases 
inventory in anticipation of customer demand that does not materialize, or if customers reduce or delay orders, Axcelis 
may incur excess inventory charges. 

We may be unable to obtain needed additional capital to finance our operations. 

Our capital requirements may vary widely from quarter to quarter, depending on, among other things, capital 
expenditures, fluctuations in our operating results, financing activities, acquisitions and investments and inventory and 
receivables management. We believe that our existing cash and cash equivalents will be sufficient to satisfy our 
anticipated cash requirements. A number of factors, including those described in these “Risk Factors,” could prove our 
assumptions wrong and cause us to require additional capital from external sources. Depending on market conditions, 
future debt or equity financings may not be possible on attractive terms or at all. In addition, future debt or equity 
financings could be dilutive to the existing holders of our common stock. 

13 

 
 
 
 
 
 
 
 
 
 
 
Our international operations involve currency risk. 

Substantially all of our sales are billed in U.S. dollars, thereby reducing the impact of fluctuations in foreign 

exchange rates on our results. However, the aftermarket revenues of our non-U.S. subsidiaries, and most of the operating 
expenses of these non-U.S. subsidiaries, are received and incurred in local currencies.  The translation of these operating 
results into U.S. dollars in our Consolidated Statement of Operations can result in other income (expense).  Similarly, the 
translation of asset and liability values to U.S. dollars are recorded in stockholders’ equity as an element of accumulated 
other comprehensive income (loss).  Accordingly, fluctuations in exchange rates can impact reported revenues, expense, 
profitability and asset values in our Consolidated Financial Statements. During the year ended December 31, 2016, 
approximately 28.4% of our revenue was derived from foreign operations with this inherent risk. In addition, at 
December 31, 2016, our operations outside of the United States accounted for approximately 20.1% of our total assets, 
the majority of which was denominated in currencies other than the U.S. dollar.  

Axcelis is exposed to risks related to cybersecurity threats and incidents. 

In the conduct of its business, Axcelis collects, uses, transmits and stores data on information technology 

systems. This data includes confidential information belonging to Axcelis or its customers or other business partners, as 
well as personally-identifiable information of individuals. Axcelis has been and expects to be subject to cybersecurity 
threats and incidents, ranging from employee error or misuse to individual attempts to gain unauthorized access to 
information systems to sophisticated and targeted measures known as advanced persistent threats, none of which have 
been material to the Company to date. Axcelis devotes significant resources to network security, data encryption and 
other measures to protect its systems and data from unauthorized access or misuse. However, depending on their nature 
and scope, cybersecurity incidents could result in business disruption; the misappropriation, corruption or loss of 
confidential information and critical data (Axcelis’ and that of third parties); reputational damage; litigation with third 
parties; diminution in the value of Axcelis’ investment in research, development and engineering; data privacy issues; 
and increased cybersecurity protection and remediation costs. 

Our proprietary technology may be vulnerable to efforts by competitors to challenge or design around, potentially 
reducing our market share. 

We rely on a combination of patents, copyrights, trademark and trade secret laws, non-disclosure agreements 
and other intellectual property protection methods to protect our proprietary technology. Despite our efforts to protect 
our intellectual property, our competitors may be able to challenge, design around or legitimately use the proprietary 
technology embedded in our systems or other technology or information used in our business. If this occurs, the value of 
our proprietary technology will be diminished. Our means of protecting our proprietary rights may not be adequate and 
our patents may not be sufficient to prevent others from using technology that is similar to or the same as our technology. 
Patents issued to us have been, or might be challenged, and might be invalidated or circumvented and any rights granted 
under our patents may not provide adequate protection to us. Our competitors may independently develop similar 
technology, duplicate features of our products or design around patents that may be issued to us. As a result of these 
threats to our proprietary technology, we may have to resort to costly litigation to enforce or defend our intellectual 
property rights. Finally, all patents expire after a period of time (in the U.S., patents expire 20 years from the date of 
filing of the patent application). Our market share could be negatively impacted by the expiration of a patent which had 
created a barrier for our competitors. 

Axcelis also has agreements with third parties for licensing of patented or proprietary technology with Axcelis 

as the licensor or the licensee. Termination of license agreements or claims of infringement with respect to such 
technology could have an adverse impact on our financial performance or ability to ship products with existing 
configurations. 

14 

 
 
 
 
 
We (or customers that we indemnify) might face intellectual property infringement claims or patent disputes that may 
be costly to resolve and, if resolved against us, could be very costly to us and prevent us from making and selling our 
systems. 

From time to time, claims and proceedings have been or may be asserted against us relative to patent validity or 

infringement matters. We typically agree to indemnify our customers from liability to third parties for intellectual 
property infringement arising from the use of our products in their intended manner. Therefore, we occasionally receive 
notification from customers who believe that we owe them indemnification or other obligations related to infringement 
claims made against the customers by third parties. Our involvement in any patent dispute or other intellectual property 
dispute or action to protect trade secrets, even if the claims are without merit, could be very expensive and could divert 
the attention of our management. Adverse determinations in any litigation could subject us to significant liabilities to 
third parties, require us to remove certain features from our products or seek costly licenses from third parties or prevent 
us from manufacturing and selling our systems. In addition, infringement indemnification clauses in system sale 
agreements may require us to take other actions or require us to provide certain remedies to customers who are exposed 
to indemnified liabilities. Any of these situations could have a material adverse effect on our business results. 

If operations were disrupted at Axcelis’ primary manufacturing facility, it would have a negative impact on our 
business. 

We have one primary manufacturing facility located in Massachusetts. Its operations could be subject to 

disruption for a variety of reasons, including, but not limited to natural disasters, work stoppages, operational facility 
constraints and terrorism. Such disruption could cause delays in shipments of products to our customers and could result 
in cancellation of orders or loss of customers, which could seriously harm our business. 

Item 1B.  Unresolved Staff Comments. 

None. 

Item 2.  Properties. 

We lease our principal facility in Beverly, Massachusetts, which comprises 417,000 square feet. The facility is 

principally used for manufacturing, research and development, sales/marketing, customer support, advanced process 
development, product demonstration, customer-training center and corporate headquarters. We believe that our 
manufacturing facilities and equipment generally are well maintained, in good operating condition, suitable for our 
purposes, and adequate for our present operations.  

We own 23 acres of undeveloped property in Beverly, Massachusetts, adjacent to our headquarters. 

As of December 31, 2016, the Company also leased 41 other properties, of which 11 are located in the United 
States and the remainder are located in Asia and Europe, including offices in Taiwan, Singapore, South Korea, China, 
Malaysia, Japan, Italy and Germany. These properties are used for sales and service offices and warehousing. 

Our Beverly, Massachusetts facility is ISO 9001:2008 and ISO 14001:2004 and our European office is 

ISO 9001:2008 certified. 

Item 3.  Legal Proceedings. 

The Company is not presently a party to any litigation that it believes might have a material adverse effect on its 

business operations. The Company is, from time to time, a party to litigation that arises in the normal course of its 
business operations.

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

Certain statements in “Management’s Discussion and Analysis of Financial Condition and Results of 

Operations” are forward-looking statements that involve risks and uncertainties. Words such as may, will, should, 
would, anticipates, expects, intends, plans, believes, seeks, estimates and similar expressions identify such 
forward-looking statements. The forward-looking statements contained herein are based on current expectations and

Overview 

The semiconductor capital equipment industry is subject to significant cyclical swings in capital spending by 

semiconductor chip manufacturers. Capital spending is influenced by demand for semiconductors and the products using 
them, the utilization rate and capacity of existing semiconductor chip manufacturing facilities and changes in 
semiconductor technology, all of which are outside of our control. As a result, our revenue may fluctuate from year to 
year and period to period. Our established cost structure does not vary significantly with changes in volume. We may 
also experience fluctuations in operating results and cash flows depending on our revenue level. 

2016 was a challenging year for the Company. Our 2016 revenues of $267.0 million were below our 2015 
revenues due to lower purchasing from key memory customers, particularly in DRAM. Despite this, Axcelis made 
progress towards our long-term strategic goal of regaining a position of market share leadership in the ion implant 
semiconductor capital equipment market. 

In 2016 we continued to invest a significant portion of our resources in research and development programs 

related to our Purion ion implantation platform.  During the year, our customer base for Purion ion implanters expanded 
significantly, and we successfully introduced several new extensions to our core Purion systems, such as the hot silicon 
carbide Purion M, the Purion EXE and Purion VXE. We placed Purion ion implanters with seven new customers, as well 
as within seven new fabs owned by existing customers.  We expect customer adoption and demand for our Purion 
products to continue to grow. 

In addition, we continued to improve our gross margin performance in 2016. The Company’s gross margins for 

2016 were 37.3%, up from 33.7% in 2015. We also worked hard to ensure that manufacturing and operating expense 
levels remain well aligned to business conditions. We believe that the most fundamental interest of our stockholders is in 
consistent, profitable, financial performance and we expect to deliver such results in 2017. 

Consolidation and partnering within the semiconductor chip manufacturing industry has resulted in a smaller 

number of customers. Our net revenue from our ten largest customers accounted for 70.2% of total revenue for the year 
ended December 31, 2016 compared to 76.8% and 68.1% of revenue for the years ended December 31, 2015 and 2014, 
respectively. For the year ended December 31, 2016, the Company had one customer representing 17.0% of total 
revenue. 

Critical Accounting Estimates 

Management’s discussion and analysis of our financial condition and results of operations are based upon 
Axcelis’ consolidated financial statements, which have been prepared in accordance with accounting principles generally 
accepted in the United States. The preparation of these financial statements requires management to make estimates and 
judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of 
contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions. Management’s 
estimates are based on historical experience and on various other assumptions that are believed to be reasonable under 
the circumstances, the results of which form the basis for making judgments about the carrying values of assets and 

18 

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

We believe the following accounting policies are critical in the portrayal of our financial condition and results of 

operations and require management’s most significant judgments and estimates in the preparation of our consolidated 
financial statements. For additional accounting policies see Note 2 to the consolidated financial statements for the year 
ended December 31, 2016 included in this Annual Report on Form 10-K.  

Revenue Recognition 

Our revenue recognition policy involves significant judgment by management. As described below, we consider 

a broad array of facts and circumstances in determining when to recognize revenue, including contractual service 
obligations to the customer, the complexity of the customer’s post-delivery acceptance provisions, payment history, 
customer creditworthiness and the installation process.  

Our system sales transactions are made up of multiple elements, including the system itself and elements that 

are not delivered simultaneously with the system. These undelivered elements might include a combination of 
installation services, extended warranty and support and spare parts, all of which are generally covered by a single sales 
price. 

Our system revenue arrangements with multiple elements are divided into separate units of accounting if 

specified criteria are met, including whether the delivered element has stand-alone value to the customer. If the criteria 
are met, then the consideration received is allocated among the separate units based on their relative selling price, and the 
revenue is recognized separately for each of the separate units. 

We determine selling price for each unit of accounting (element) using vendor specific objective evidence 

(“VSOE”) or third-party evidence (“TPE”), if they exist, otherwise, we use best estimated selling price (“BESP”). We 
generally expect that we will not be able to establish TPE due to the nature of our products, and, as such, we typically 
will determine selling price using VSOE or BESP. 

Where required, we determine BESP for an individual element based on consideration of both market and 
Company-specific factors, including the selling price and profit margin for similar products, the cost to produce the 
deliverable and the anticipated margin on that deliverable and the characteristics of the markets in which the deliverable 
is sold. 

Systems are not sold separately and VSOE or TPE is not available for the systems element. Therefore the 

selling price associated with systems is based on BESP. The allocated value for installation in the arrangement includes 
the either (i) the relative selling price of the installation or (ii) the portion of the sales price that will not be received until 
the installation is completed (the “retention”). The selling price of elements such as extended warranty for support, spare 
parts and support labor is also based on BESP. For the majority of regions, the selling price of installation is based upon 
the fair value of the service performed, including labor, which is based upon the estimated time to complete the 
installation at hourly rates, and material components, both of which are sold separately, or VSOE. In regions where 
VSOE does not exist the Company uses BESP. 

Product revenue for products which have demonstrated market acceptance is generally recognized upon 
shipment provided title and risk of loss has passed to the customer, evidence of an arrangement exists, prices are 
contractually fixed or determinable, collection is reasonably assured through historical collection results and regular 
credit evaluations and there are no uncertainties regarding customer acceptance. Revenue from installation services is 
recognized at the time acceptance has occurred, as defined in the sales documentation, or, for certain customers, when 
both the acceptance has occurred and retention payment has been received. Revenue for other elements is recognized at 
the time products are shipped or the related services are performed. 

We generally recognize product revenue for systems which have demonstrated market acceptance at the time of 
shipment because the customer’s post-delivery acceptance provisions and installation process have been established to be 

19 

 
 
 
 
 
 
 
 
 
 
routine, commercially inconsequential and perfunctory. We believe the risk of failure to complete a system installation is 
remote. 

For initial shipments of systems with new technologies or in the small number of instances where we are unsure 

of meeting the customer’s specifications or obtaining customer acceptance upon shipment of the system, we will defer 
the recognition of systems revenue and related costs until written customer acceptance of the system is obtained. This 
deferral period is generally within twelve months of shipment. 

Impairment of Long-Lived Assets 

We record impairment losses on long-lived assets when events and circumstances indicate that these assets 

might not be recoverable. Recoverability is measured by a comparison of the assets’ carrying amount to their expected 
future undiscounted net cash flows. If such assets are considered to be impaired, the impairment is measured based on 
the amount by which the carrying value exceeds its fair value. 

Actual performance could be materially different from our current forecasts, which could impact estimates of 
undiscounted cash flows and may result in the impairment of the carrying amount of the long-lived assets in the future. 
This could be caused by strategic decisions made in response to economic and competitive conditions, the impact of the 
economic environment on our customer base or a material adverse change in our relationships with significant 
customers. 

We did not record an impairment charge in the years ended December 31, 2016, 2015 or 2014. 

Accounts Receivable—Allowance for Doubtful Accounts 

We record an allowance for doubtful accounts for estimated losses resulting from the inability of our customers 

to make required payments. Our allowance for doubtful accounts is established based on a specific assessment of 
collectability of our customer accounts. If the financial condition of our customers were to deteriorate, resulting in an 
impairment of their ability to make payments, additional allowances may be necessary. 

Inventory—Allowance for Excess and Obsolescence and Lower of Cost or Market 

We record an allowance for estimated excess and obsolete inventory and lower of cost or market. The allowance 

is determined using management’s assumptions of materials usage, based on estimates of forecasted and historical 
demand and market conditions. If actual market conditions become less favorable than those projected by management, 
additional inventory write-downs may be required. 

Although we make every effort to ensure the accuracy of our forecasts or product demand and pricing 
assumptions, any significant unanticipated changes in demand, pricing, or technical developments would significantly 
impact the value of our inventory and our reported operating results. In the future, if we determine that inventory needs 
to be written down, the Company will recognize such costs in our cost of revenue at the time of such determination. If we 
subsequently sell product that has previously been written down, our gross margin in that period will be favorably 
impacted. 

Product Warranty 

We generally offer a one year warranty for all of our systems, the terms and conditions of which vary depending 
upon the product sold. For all systems sold, we accrue a liability for the estimated cost of standard warranty at the time of 
system shipment and defer the portion of systems revenue attributable to the relative fair value of non-standard warranty. 
Costs for non-standard warranty are expensed as incurred. Factors that affect our warranty liability include the number of 
installed units, historical and anticipated product failure rates, material usage and service labor costs. We periodically 
assess the adequacy of our recorded liability and adjust the amount as necessary. 

20 

 
 
 
 
 
 
 
 
 
 
 
 
 
Stock-based Compensation 

Stock-based compensation expense for stock options with time-based conditions is estimated as of the grant 

date based on the fair value of the award and is recognized as expense over the requisite service period, which generally 
equals the vesting period, based on the number of awards that are expected to vest. Estimating the fair value for stock 
options requires judgment, including the expected term of our stock options, volatility of our stock, expected dividends, 
risk-free interest rates over the expected term of the options and the expected forfeiture rate. 

We considered a number of factors when estimating volatility. Our method of estimating expected volatility for 

all stock options granted relies on a combination of historical and implied volatility. We believe that this blended 
volatility results in a more accurate estimate of the grant-date fair value of employee stock options because it more 
appropriately reflects the market’s current expectations of future volatility. 

In limited circumstances, we also issue stock option grants with vesting based on performance or market 
conditions, such as the price of our common stock, or, a combination of time, performance or market conditions. The fair 
values and derived service periods for all grants that have vesting based on performance or market conditions are 
estimated using the Monte Carlo valuation method. For each stock option grant with vesting based on a combination of 
time or market conditions, where vesting will occur if either condition is met, the related compensation costs are 
recognized over the shorter of the explicit service period or the derived service period. 

We use the straight-line attribution method to recognize expense for stock-based awards such that the expense 

associated with awards is evenly recognized throughout the period. 

The amount of stock-based compensation recognized is based on the value of the portion of the awards that are 

ultimately expected to vest. We estimate forfeitures at the time of grant and revise them, if necessary, in subsequent 
periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or 
“expirations” and represents only the unvested portion of the surrendered stock-based award. 

The benefits of tax deductions in excess of recognized compensation cost is reported as a financing cash flow, 

rather than as an operating cash flow. Because the Company does not recognize the benefit of tax deductions in excess of 
recognized compensation cost due to its cumulative net operating loss position, this had no impact on the Company’s 
consolidated statement of cash flows for the years ended December 31, 2016, 2015 and 2014. 

Income Taxes 

We record income taxes using the asset and liability method. Deferred income tax assets and liabilities are 

recognized for the future tax consequences attributable to differences between the financial statement carrying amounts 
of existing assets and liabilities and their respective income tax basis, and net operating loss and tax credit carryforwards. 

Our consolidated financial statements contain certain deferred tax assets which have arisen primarily as a result 

of operating losses, as well as other temporary differences between financial and income tax accounting. 

We establish a valuation allowance when it is more likely than not that some portion or all of the deferred tax 

assets will not be realized. Significant management judgment is required in determining our provision for income taxes, 
the deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. 

We evaluate the weight of all available evidence such as historical losses, projected future taxable income and 

the expected timing of the reversals of existing temporary differences to determine whether it is more likely than not that 
some portion or all of the net deferred income tax assets will not be realized. 

Based on our level of deferred tax assets as of December 31, 2016 and our level of historical U.S. losses, we 

have determined that the current uncertainty regarding the realization of these assets is sufficient to warrant the need for 
a full valuation allowance against our U.S. net deferred tax assets. We have also determined that a valuation allowance is 
required on a portion of our foreign deferred tax assets. 

21 

 
 
 
 
 
 
 
 
 
 
 
 
Our income tax expense includes the largest amount of tax benefit for an uncertain tax position that is more 

likely than not to be sustained upon audit based on the technical merits of the tax position. Settlements with tax 
authorities, the expiration of statutes of limitations for particular tax positions, or obtaining new information on particular 
tax positions may cause a change to the effective tax rate. The Company recognizes accrued interest related to 
unrecognized tax benefits as interest expense and penalties as operating expense.

2016 Compared with 2015 

Product 

Product revenue, which includes new system sales, sales of spare parts, product upgrades and used system sales 

was $244.3 million or 91.5% of revenue in 2016, compared with $278.9 million, or 92.5% of revenue in 2015. The 
decrease in product revenue in 2016 was primarily driven by a decrease in the number of Purion systems sold due to an 
unexpected decline in DRAM spending. 

Approximately 38.9% of systems revenue in 2016 was from sales of 200mm products and 61.1% was from 

sales of 300mm products, compared with 13.0% and 87.0% for sales of 200mm products and 300mm products in 2015, 
respectively. The increase in 200mm system sales is attributed to a resurgence in the mature process technology segment 
including shipments of both legacy and 200mm Purion systems 

A portion of our revenue from system sales is deferred until installation and other services related to future 

deliverables are performed. The total amount of deferred revenue at December 31, 2016 and 2015 was $11.0 million and 
$8.5 million, respectively. The increase was primarily due to a prepayment of a system sale. 

Services 

Services revenue, which includes the labor component of maintenance and service contracts and fees for service 

hours provided by on-site service personnel, was $22.7 million, or 8.5% of revenue for 2016, compared with 
$22.6 million, or 7.5% of revenue for 2015. Although services revenue should increase with the expansion of the 
installed base of systems, it can fluctuate from period to period based on capacity utilization at customers’ manufacturing 
facilities, which affects the need for equipment service. 

2015 Compared with 2014 

Product 

Product revenue was $278.9 million or 92.5% of revenue in 2015, compared with $179.2 million, or 88.3% of 
revenue in 2014. The increase in product revenue in 2015 was primarily driven by an increase in the number of Purion 
systems sold. 

Approximately 13.0% of systems revenue in 2015 was from sales of 200mm products and 87.0% was from 

sales of 300mm products, compared with 18.1% and 81.9% for sales of 200mm products and 300mm products in 2014, 
respectively.

The total amount of deferred revenue at December 31, 2015 and 2014 was $8.5 million and $7.2 million, 
respectively. The increase was mainly due to the increase in systems sales in 2015 and the timing of acceptance of 
deferred system sales. 

Services 

Services revenue was $22.6 million, or 7.5% of revenue for 2015, compared with $23.8 million, or 11.7% of 

revenue for 2014.  

Revenue Categories used by Management 

In addition to the line item revenue categories discussed above, management also uses revenue categorizations 

which look at revenue by product line (the most significant of which is ion implant) and by aftermarket, as described 
below. 

2016 Compared with 2015 

Ion Implant 

Revenue from sales of ion implantation products and related service was $248.9 million, or 93.2% of total 

revenue in 2016, compared with $282.6 million, or 93.2%, of total revenue in 2015.  

Aftermarket 

We refer to the business of selling spare parts, product upgrades, and used systems, combined with the sale of 

maintenance labor and service contracts and service hours, as the “aftermarket” business. Revenue from our aftermarket 
business was $127.7 million in 2016, which decreased slightly compared to $129.6 million for 2015. Aftermarket 
revenue generally increases with the expansion of the installed base of systems but can fluctuate from period to period 
based on capacity utilization at customers’ manufacturing facilities which affects the sale of spare parts and demand for 
equipment service. 

2015 Compared with 2014 

Ion Implant 

Revenue from sales of ion implantation products and related service was $282.6 million, or 93.7% of total 

revenue in 2015, compared with $183.1 million, or 90.2%, of total revenue in 2014. The increase in ion implant’s share 
of total revenue for 2015 reflects a continuing reduction in dry strip revenue following the sale of assets relating to the 
dry strip product line in December 2012. Total revenue in ion implant increased as our market share increased in 2015 
due to our Purion products. 

Aftermarket 

Revenue from our aftermarket business was $129.6 million in 2015, which increased moderately compared to 

$121.4 million for 2014.

Product 

Gross margin from product revenue was 39.0% for the twelve months ended December 31, 2016, compared to 
35.1% for the twelve months ended December 31, 2015. The increase in gross margin of 3.9% resulted from improved 
margins on Purion systems as a result of continued focus on supply chain optimization, value engineering and lean 
performance, combined with an increased mix of higher margin parts and upgrades.  

Services 

Gross margin from services revenue was 19.0% for the twelve months ended December 31, 2016, compared to 

17.2% for the twelve months ended December 31, 2015. The increase in gross margin is attributable to lower service 
costs and higher margin service revenues. 

2015 Compared with 2014 

Product 

Gross margin from product revenue was 35.1% for the twelve months ended December 31, 2015, compared to 

36.8% for the twelve months ended December 31, 2014. The decrease in gross margin resulted from the net effect of 
significantly higher systems sales volume of new Purion systems at lower margins and a decreased mix of parts and 
upgrade revenue, partially offset by sale of previously written down systems. 

Services 

Gross margin from services revenue was 17.2% for the twelve months ended December 31, 2015, compared to 

17.7% for the twelve months ended December 31, 2014. The decrease in gross margin is due to lower volumes and 
changes in the mix and timing of service contracts.

Our operating expenses consist primarily of personnel costs, including salaries, commissions, bonuses, stock-

based compensation and related benefits and taxes; project material costs related to the design and development of new 
products and enhancement of existing products; and professional fees, travel and depreciation expenses. Personnel costs 
are our largest expense, representing $47.6 million, or 57.5% of our total operating expenses, for the year ended 
December 31, 2016; $47.9 million, or 59.1%, of our total operating expenses for the year ended December 31, 2015; and 
$45.3 million, or 57.9%, of our total operating expenses, excluding the restructuring charge of $2.6 million for the year 
ended December 31, 2014.

Our ability to remain competitive depends largely on continuously developing innovative technology, with new 
and enhanced features and systems and introducing them at competitive prices on a timely basis. Accordingly, based on 
our strategic plan, we establish annual R&D budgets to fund programs that we expect will drive competitive advantages. 

2016 Compared with 2015 

Research and development expense was $34.4 million in 2016, an increase of approximately $1.8 million, or 

5.6%, compared with $32.6 million in 2015. The increase was primarily due to increased headcount and outside services 
to support product enhancements of our Purion platform partially offset by lower variable incentive plan expense. 

2015 Compared with 2014 

Research and development expense was $32.6 million in 2015, a decrease of approximately $0.9 million, or 

2.8%, compared with $33.5 million in 2014. The decrease was primarily due to lower personnel costs driven by reduced 
headcount from a reduction in force in 2014 and a spike in labor and material costs in the prior year related to the rollout 
of our Purion platform. This was partially offset by higher variable incentive plan expense in 2015.

Our sales and marketing expenses result primarily from the sale of our equipment and services through our 

direct sales force. 

2016 Compared with 2015 

Sales and marketing expense was $23.8 million in 2016, an increase of $0.5 million, or 2.2%, compared with 

$23.3 million in 2015. The increase was primarily due to an increase in new tool evaluation costs. 

2015 Compared with 2014 

Sales and marketing expense was $23.3 million in 2015, an increase of $2.6 million, or 12.6%, compared with 

$20.7 million in 2014. The increase was primarily due to variable incentive plan expense and other compensation 
expense as well as higher new tool evaluation costs.

Our general and administrative expenses result primarily from the costs associated with our executive, finance, 

information technology, legal and human resource functions. 

2016 Compared with 2015 

General and administrative expense was $24.5 million in 2016, a decrease of $0.6 million, or 2.4% compared 

with $25.1 million in 2015. The decrease was primarily due to a reduction in personnel costs driven by a decrease in 
variable incentive plan expense. 

2015 Compared with 2014 

General and administrative expense was $25.1 million in 2015, an increase of $1.1 million, or 4.6% compared 

with $24.0 million in 2014. The increase was primarily due to variable incentive plan expense. 

Restructuring 

The Company from time to time incurs expenses relating to restructuring.  

2016 Compared with 2015 

During the year ended December 31, 2016 we recorded $0.3 million to restructuring expense due to a 

consolidation in our customer base. During the year ended December 31, 2015, we recorded an immaterial charge to 
restructuring expense.

2015 Compared with 2014 

During the year ended December 31, 2015 we recorded an immaterial charge to restructuring expense. During 

the year ended December 31, 2014 we recorded $2.6 million in restructuring expense for severance and other related 
costs. 

Other (Expense) Income 

Other (expense) income consists primarily of interest relating to the lease obligation we incurred in connection 
with the 2015 sale of our headquarters facility (“sale leaseback”) and other financing obligations, foreign exchange gains 
and losses attributable to fluctuations of the U.S. dollar against the local currencies of certain of the countries in which 
we operate, as well as interest earned on our invested cash balances. 

2016 Compared with 2015 

Other expense for the years ended December 31, 2016 and 2015 was $5.5 million and includes interest related 

to our sale leaseback obligation of $5.1 million and $4.8 million, respectively.  

2015 Compared with 2014 

Other expense for the year ended December 31, 2015 of $5.5 million consists primarily of $4.8 million of 

interest related to our sale leaseback obligation. Other income for the year ended December 31, 2014 of $0.5 million 
consists primarily of foreign exchange gain of $1.8 million offset partially by interest expense of $1.1 million associated 
with the business loan agreement with Northern Bank & Trust Company (“Term Loan”). 

Income Taxes 

Income tax expense was less than $0.1 million, $0.5 million and $1.1 million for the year ended December 31, 

2016, 2015 and 2014, respectively. Our income tax expense is primarily due to operating results of foreign entities in 
jurisdictions in Europe and Asia, where we earn taxable income. We have significant net operating loss carryforwards in 
the United States and certain European jurisdictions, and, as a result, we do not currently pay significant income taxes in 
those jurisdictions. Additionally, we do not recognize the tax benefit for such losses in the United States and certain 
European taxing jurisdictions until it is determinable that there will be sufficient income such that the tax benefits can be 
recognized. 

Liquidity and Capital Resources 

Our liquidity is affected by many factors. Some of these relate specifically to the operations of our business, for 

example, our sales and other factors relate to the uncertainties of global economies, including the availability of credit 
and the condition of the overall semiconductor capital equipment industry. Our established cost structure does not vary 
significantly with changes in volume. We experience fluctuations in operating results and cash flows depending on 
fluctuations in our revenue level. 

In 2016, $8.8 million of cash was used to support operating activities. This compares to $18.3 million of cash 

provided by operating activities in 2015. Cash and cash equivalents at December 31, 2016 was $70.8 million, compared 
to $78.9 million at December 31, 2015. Approximately $16.4 million of cash was located in foreign jurisdictions as of 
December 31, 2016. In addition to the cash and cash equivalent balance at December 31, 2016, the Company had 
$6.9 million in restricted cash which relates to a $5.9 million letter of credit associated with the security deposit for the 
sale leaseback transaction, a $0.9 million letter of credit relating to workers’ compensation insurance, and a $0.1 million 
deposit relating to customs activity. Working capital at December 31, 2016 was $193.0 million. At December 31, 2016, 
the Company had no bank debt. 

Capital expenditures were $2.5 million and $1.8 million for the years ended December 31, 2016 and 2015, 

respectively. Total capital expenditures for 2017 are projected to be approximately $7.5 million. Future capital 

28 

 
 
 
 
 
 
 
 
 
 
 
 
 
expenditures beyond 2017 will depend on a number of factors, including the timing and rate of expansion of our business 
and our ability to generate cash to fund them. 

Cash provided by financing activities was $2.4 million and $31.4 million for the years ended December 31, 

2016 and 2015, respectively. The $2.4 million cash provided by financing activities in 2016 was mainly due to the 
exercise of stock options and proceeds received from the employee stock purchase plan.  

The $31.4 million cash provided by financing activities from the prior year resulted largely from the first quarter 

2015 sale of our corporate headquarters building in Beverly, Massachusetts, which provided $48.9 million of gross 
proceeds, less $0.4 million for prepaid rent, for a net amount of $48.5 million. At the time of this sale, the Company 
discharged an outstanding term loan of $14.4 million, with related accrued interest, and paid a pre-payment penalty to 
Northern Bank and Trust Company for a total payment of $14.8 million. The Company incurred $0.8 million of related 
financing expenses associated with this transaction and entered into a 22-year leaseback of the facility, the financial 
commitment for which is included in the table of contractual obligations below. The Company also received proceeds of 
$4.4 million relating to the exercise of stock options and purchases of Company stock through the Employee Stock 
Purchase Plan. 

We have outstanding letters of credit and surety bonds in the amount of $9.0 million to support our sale 

leaseback, workers’ compensation insurance program and certain value added tax claims in Europe.

We have no off-balance sheet arrangements at December 31, 2016, exclusive of operating leases. 

We have net operating loss and tax credit carryforwards, the tax effect of which aggregate $115.6 million at 

December 31, 2016. These carryforwards, which expire principally between 2017 and 2034, are available to reduce 
future income tax liabilities in the United States and certain foreign jurisdictions. 

It is Company policy to provide taxes for the total anticipated tax impact of the undistributed earnings of our 

wholly-owned foreign subsidiaries, as such earnings are not expected to be reinvested indefinitely. The Company 
anticipates that U.S. tax resulting from remitting such earnings will be off-set by net operating loss or credit 
carryforwards to the extent available. In addition, the Company does not anticipate incurring a foreign withholding tax 
on remitting such earnings since it does not intend to remit the earnings as dividends. 

We believe that based on our current market, revenue, expense and cash flow forecasts, our existing cash, cash 

equivalents and borrowing capacity will be sufficient to satisfy our anticipated cash requirements for the short and

terms if needed. 

Related-Party Transactions 

There are no significant related-party transactions that require disclosure in the consolidated financial statements 

for the year ended December 31, 2016, or in this Annual Report on Form 10-K. 

Recent Accounting Pronouncements 

A discussion of recent accounting pronouncements, the impact of some of which may be material, is included in 
Note 2 to the consolidated financial statements for the year ended December 31, 2016 included in this Annual Report on 
Form 10-K. 

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk. 

Interest Rate Sensitivity 

Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio, which 

consists entirely of cash equivalents at December 31, 2016. The primary objective of our investment activities is to 
preserve principal while maximizing yields without significantly increasing risk. This is accomplished by investing in 
marketable high investment grade securities. We do not use derivative financial instruments in managing our investment 
portfolio. Due to the nature of our investments, we do not expect our operating results or cash flows to be affected to any 
significant degree by any change in market interest rates. 

Foreign Currency Exchange Risk 

Substantially all of our sales are billed in U.S. dollars, thereby reducing the impact of fluctuations in foreign 

exchange rates on our results. Operating margins of certain foreign operations can fluctuate with changes in foreign 
exchange rates to the extent revenue is billed in U.S. dollars and operating expenses are incurred in the local currency. 
During the years ended December 31, 2016 and 2015, approximately 28.4% and 24.7% of our revenue were derived 
from foreign operations with this inherent risk. In addition, at both December 31, 2016 and 2015, our operations outside 
of the United States accounted for approximately 20.1% and 20.7% of our total assets, respectively, the majority of 
which was denominated in currencies other than the U.S. dollar. We do not use derivative financial instruments in 
managing our foreign currency exchange risk.

Evaluation of Disclosure Controls and Procedures. 

Our management, with the participation of our principal executive officer and principal financial officer, has 

evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities 
Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this annual report (the 
“Evaluation Date”). Based on this evaluation, our principal executive officer and principal financial officer concluded 
that, as of the Evaluation Date, these disclosure controls and procedures are effective.

Internal Control over Financial Reporting 

Management’s Annual Report on Internal Control over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting, 

as such term is defined in Rule 13a-15(f) under the Exchange Act. Because of its inherent limitations, internal control 
over financial reporting may not prevent or detect all misstatements. A control system, no matter how well designed and 
operated, can provide only reasonable assurance with respect to financial statement preparation and presentation. 
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. 

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. 

In making this assessment, management used the criteria set forth in the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO) Internal Control—2013 Integrated Framework. 

Based on this assessment, management has concluded that, as of December 31, 2016, our internal control over 

financial reporting is effective based on those criteria. 

The independent registered public accounting firm of Ernst & Young LLP, as auditors of our consolidated 

financial statements, has issued an attestation report on its assessment of our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders of Axcelis Technologies, Inc. 

We have audited Axcelis Technologies, Inc.’s internal control over financial reporting as of December 31, 2016, 

based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Axcelis Technologies, Inc.’s 
management is responsible for maintaining effective internal control over financial reporting, and for its assessment of 
the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal 
control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 

(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether 
effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an 
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and 
evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis 
for our opinion. 

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

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

In our opinion, Axcelis Technologies, Inc. maintained, in all material respects, effective internal control over 

financial reporting as of December 31, 2016, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated balance sheets of Axcelis Technologies, Inc. as of December 31, 2016 and 2015, and 
the related consolidated statements of operations, comprehensive income, changes in stockholders’ equity and cash flows 
for each of the three years in the period ended December 31, 2016 of Axcelis Technologies, Inc. and our report dated 
March 14, 2017 expressed an unqualified opinion thereon.

Changes in Internal Control over Financial Reporting 

There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the 

Exchange Act) identified in connection with the evaluation of our internal control that occurred during our fourth quarter 
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

The Board of Directors and Stockholders of Axcelis Technologies, Inc. 

We have audited the accompanying consolidated balance sheets of Axcelis Technologies, Inc. as of December 

31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income, changes in 
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2016. Our audits also 
include the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the 
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 
and schedule based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether 
the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting 
principles used and significant estimates made by management, as well as evaluating the overall financial statement 
presentation. We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated 

financial position of Axcelis Technologies, Inc. at December 31, 2016 and 2015, and the consolidated results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2016, in conformity with U.S. 
generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered 
in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set 
forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 

(United States), Axcelis Technologies, Inc.’s internal control over financial reporting as of December 31, 2016, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework) and our report dated March 14, 2017 expressed an unqualified opinion 
thereon.

Axcelis Technologies, Inc. 
Notes to Consolidated Financial Statements 

Note 1. Nature of Business 

Axcelis Technologies, Inc. (“Axcelis” or the “Company”) was incorporated in Delaware in 1995, and is a 

worldwide producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips 
in the United States, Europe and Asia. In addition, the Company provides extensive aftermarket service and support, 
including spare parts, equipment upgrades, used equipment and maintenance services to the semiconductor industry. 

Note 2. Summary of Significant Accounting Policies 

The accompanying consolidated financial statements reflect the application of certain significant accounting 

policies as described in this note and elsewhere in the footnotes. 

(a)          Basis of Presentation 

The accompanying consolidated financial statements include the accounts of the Company and its 
wholly-owned, controlled subsidiaries. All intercompany balances and transactions have been eliminated in 
consolidation. 

Events occurring subsequent to December 31, 2016 have been evaluated for potential recognition or disclosure 

in the consolidated financial statements. 

(b)          Use of Estimates 

The preparation of these consolidated financial statements in conformity with accounting principles generally 

accepted in the United States of America requires management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial 
statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the 
Company evaluates its estimates and judgments, including those related to revenue recognition, the realizable value of 
inventories, valuing stock-based compensation instruments and valuation allowances for deferred tax assets. Actual 
amounts could differ from these estimates. Changes in estimates are recorded in the period in which they become known. 

(c)          Foreign Currency 

The functional currency for substantially all operations outside the United States is the local currency. Financial 

statements for these operations are translated into United States dollars at year-end rates as to assets and liabilities and 
average exchange rates during the year as to revenue and expenses. The resulting translation adjustments are recorded in 
stockholders’ equity as an element of accumulated other comprehensive income (loss). Foreign currency transaction 
gains and losses are included in other income (expense) in the Consolidated Statements of Operations. 

For the year ended December 31, 2016 the Company had $0.6 million in foreign exchange losses. For the year 
ended December 31, 2015 the Company did not have any material foreign exchange gains or losses. For the year ended 
December 31, 2014, the Company realized $1.8 million of foreign exchange gains.  

(d)          Cash and Cash Equivalents 

Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of 

ninety days or less. Cash equivalents consist primarily of money market securities and certificates of deposit. Cash 
equivalents are carried on the balance sheet at fair market value. 

42 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(e)          Inventories 

Inventories are carried at lower of cost, determined using the first-in, first-out (“FIFO”) method, or market. The 
Company periodically reviews its inventories and makes provisions as necessary for estimated obsolescence or damaged 
goods to ensure values approximate lower of cost or market. The amount of such markdowns is equal to the difference 
between cost of inventory and the estimated market value based upon assumptions about future demands, selling prices, 
and market conditions. 

The Company records an allowance for estimated excess inventory. The allowance is determined using 

management’s assumptions of materials usage, based on estimates of demand and market conditions. If actual market 
conditions become less favorable than those projected by management, additional inventory write-downs may be 
required. 

(f)          Property, Plant and Equipment 

Property, plant and equipment are stated at cost, less accumulated depreciation and amortization. 

Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the 

related assets as follows: 

Asset Classification 

Land and buildings (under lease) 
Machinery and equipment 

    Estimated Useful Life 

Lesser of the lease term or 
estimated useful life of the asset 

     3 to 10 years 

On January 30, 2015, the Company sold its corporate headquarters facility. As part of this sale, the Company 
also entered into a 22-year lease agreement. The Company accounted for the sale leaseback transaction as a financing 
arrangement for financial reporting purposes. The Company retained the historical costs of the property and the related 
accumulated depreciation on its financial books within property, plant and equipment and will continue to depreciate the 
property for financial reporting purposes over the lesser of its remaining useful life or its initial lease term of 22 years.   

Repairs and maintenance costs are expensed as incurred. Expenditures for renewals and betterments are 

capitalized. 

(g)          Impairment of Long-Lived Assets 

The Company records impairment losses on long-lived assets when events and circumstances indicate that these 

assets might not be recoverable. Recoverability is measured by a comparison of the assets’ carrying amount to their 
expected future undiscounted net cash flows. If such assets are considered to be impaired, the impairment is measured 
based on the amount by which the carrying value exceeds its fair value. 

The Company did not have any indicators of impairment during the period ending December 31, 2016. The 

Company did not record an impairment charge in the years ended December 31, 2016, 2015, or 2014. 

Actual performance could be materially different from our current forecasts, which could impact estimates of 
undiscounted cash flows and may result in the impairment of the carrying amount of the long-lived assets in the future. 
This could be caused by strategic decisions made in response to economic and competitive conditions, the impact of the 
economic environment on our customer base, or a material adverse change in the Company’s relationships with 
significant customers.

 (h)         Concentration of Risk and Off-Balance Sheet Risk 

Financial instruments that potentially subject the Company to concentrations of credit risk are principally cash 
equivalents and accounts receivable. The Company’s cash equivalents are principally maintained in an investment grade 
money-market fund or certificates of deposit. 

The Company has no significant off-balance-sheet risk such as exchange contracts, option contracts or other 

hedging arrangements. 

The Company’s exposure to market risk for changes in interest rates relates primarily to cash equivalents. The 
primary objective of the Company’s investment activities is to preserve principal without significantly increasing risk. 
This is accomplished by investing in marketable high investment grade securities. The Company does not use derivative 
financial instruments to manage its investment portfolio and does not expect operating results or cash flows to be 
affected to any significant degree by any change in market interest rates. 

The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires 
no collateral to secure accounts receivable. For selected overseas sales, the Company requires customers to obtain letters 
of credit before product is shipped. The Company maintains an allowance for doubtful accounts based on its assessment 
of the collectability of accounts receivable. The Company reviews the allowance for doubtful accounts monthly. The 
Company does not have any off-balance sheet credit exposure related to its customers. 

The Company’s customers consist of semiconductor chip manufacturers located throughout the world and net 

sales to its ten largest customers accounted for 70.2%, 76.8% and 68.1% of revenue in 2016, 2015 and 2014, 
respectively. 

For the year ended December 31, 2016, the Company had one customer representing 17.0% of total revenue.  

For the year ended December 31, 2015, the Company had two customers representing 29.3% and 10.5% of total revenue, 
respectively. For the year ended December 2014 the Company had two customers representing 17.4% and 12.3% of total 
revenue, respectively. 

As of December 31, 2016, the Company had four customers account for 22.0%, 12.3%, 12.0% and 10.6% of 

consolidated accounts receivable, respectively. As of December 31, 2015, the Company had three customers account for 
22.9%, 12.7% and 11.6% of consolidated accounts receivable, respectively.  

Some of the components and sub-assemblies included in the Company’s products are obtained either from a 

sole source or a limited group of suppliers. Disruption to the Company’s supply source, resulting either from economic 
conditions or other factors, could affect its ability to deliver products to its customers. 

(i)          Revenue Recognition 

The Company’s revenue recognition policy involves significant judgment by management. The Company 
considers a broad array of facts and circumstances in determining when to recognize revenue, including contractual 
obligations to the customer, the complexity of the customer’s post-delivery acceptance provisions, payment history, 
customer creditworthiness and the installation process.  

The Company’s system sales transactions are made up of multiple elements, including the system itself and 

elements that are not delivered simultaneously with the system. These undelivered elements might include a combination 
of installation services, extended warranty and support and spare parts, all of which are covered generally by a single 
sales price. 

The Company’s system revenue arrangements with multiple elements are divided into separate units of 
accounting if specified criteria are met, including whether the delivered element has stand-alone value to the customer. If 
the criteria are met, then the consideration received is allocated among the separate units based on their relative selling 
price, and the revenue is recognized separately for each of the separate units. 

44 

 
 
 
 
 
 
 
 
 
 
 
 
The Company determines selling price for each unit of accounting (element) using vendor specific objective 

evidence (VSOE) or third-party evidence (TPE), if they exist, otherwise, the Company uses best estimated selling price 
(BESP). The Company generally expects that it will not be able to establish TPE due to the nature of its products, and, as 
such, the Company typically will determine selling price using VSOE or BESP. 

Where required, the Company determines BESP for an individual element based on consideration of both 
market and Company-specific factors, including the selling price and profit margin for similar products, the cost to 
produce the deliverable and the anticipated margin on that deliverable and the characteristics of the markets in which the 
deliverable is sold. 

Systems are not sold separately and VSOE or TPE is not available for the systems element. Therefore the 

selling price associated with systems is based on BESP. The allocated value for installation in the arrangement includes 
either (i) the relative selling price of the installation or (ii) the portion of the sales price that will not be received until the 
installation is completed (the “retention”). The selling price of elements such as extended warranty for support, spare 
parts and support labor is also based on BESP.  For the majority of regions, the selling price of installation is based upon 
the fair value of the service performed, including labor, which is based upon the estimated time to complete the 
installation at hourly rates, and material components, both of which are sold separately, or VSOE. In regions where 
VSOE does not exist the Company uses BESP. 

Product revenue for products which have demonstrated market acceptance, is generally recognized upon 
shipment provided title and risk of loss has passed to the customer, evidence of an arrangement exists, prices are 
contractually fixed or determinable, collectability is reasonably assured through historical collection results and regular 
credit evaluations, and there are no uncertainties regarding customer acceptance. Revenue from installation services is 
recognized at the time acceptance has occurred, as defined in the sales documentation or, for certain customers, when 
both acceptance has occurred and retention payment has been received. Revenue for other elements is recognized at the 
time products are shipped or the related services are performed. 

The Company generally recognizes revenue for systems which have demonstrated market acceptance at the time 
of shipment because the customer’s post-delivery acceptance provisions and installation process have been established to 
be routine, commercially inconsequential and perfunctory. The Company believes the risk of failure to complete a 
system installation is remote. 

For initial shipments of systems with new technologies or in the small number of instances where the Company 
is unsure of meeting the customer’s specifications or obtaining customer acceptance upon shipment of the system, it will 
defer the recognition of systems revenue and related costs until written customer acceptance of the system is obtained. 
This deferral period is generally within twelve months of shipment. 

Revenue related to maintenance and service contracts is recognized ratably over the duration of the contracts, or 
based on parts usage, where appropriate. Revenue related to service hours is recognized when the services are performed. 

Product revenue includes revenue from system sales, sales of spare parts, the spare parts component of 
maintenance and service contracts and product upgrades. Services revenue includes the labor component of maintenance 
and service contract amounts charged for on-site service personnel. 

Axcelis reports revenue net of any taxes collected from customers and remitted to governmental authorities, 

with the collected taxes recorded as current liabilities until remitted to the relevant government authority. 

(j)          Shipping and Handling Costs 

Shipping and handling costs are included in cost of revenue. 

45 

 
 
 
 
 
 
 
 
 
 
 
(k)         Stock-Based Compensation 

The Company generally recognizes compensation expense for all stock-based payments to employees and 

directors, including grants of employee stock options, based on the grant-date fair value of those stock-based payments 
using the Black-Scholes option pricing model, adjusted for expected forfeitures. Other valuation models may be utilized 
in the limited circumstances where awards with market-based vesting considerations, such as the price of the Company’s 
common stock, or performance based awards, are granted. Stock-based compensation expense is recognized ratably over 
the requisite service period. For each stock option grant with vesting based on a combination of time, market or 
performance conditions, where vesting will occur if either condition is met, the related compensation costs are 
recognized over the shorter of the explicit service period or the derived service period. 

See Note 14 for additional information relating to stock-based compensation. 

(l)         Income Taxes 

The Company records income taxes using the asset and liability method. Deferred income tax assets and 

liabilities are recognized for the future tax consequences attributable to differences between the financial statement 
carrying amounts of existing assets and liabilities and their respective income tax basis, and operating loss and tax credit 
carryforwards. 

The Company’s consolidated financial statements contain certain deferred tax assets which have arisen 
primarily as a result of operating losses, as well as other temporary differences between financial and tax accounting. The 
Company establishes a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on 
an evaluation of objective verifiable evidence. Significant management judgment is required in determining the 
Company’s provision for income taxes, the Company’s deferred tax assets and liabilities and any valuation allowance 
recorded against those net deferred tax assets. The Company evaluates the weight of all available evidence to determine 
whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. 

Income taxes include the largest amount of tax benefit for an uncertain tax position that is more likely than not 

to be sustained upon audit based on the technical merits of the tax position. Settlements with tax authorities, the 
expiration of statutes of limitations for particular tax positions, or obtaining new information on particular tax positions 
may cause a change to the effective tax rate. The Company recognizes accrued interest related to unrecognized tax 
benefits as interest expense and penalties as operating expense in the consolidated statements of operations. 

(m)         Computation of Net Income (Loss) per Share 

Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by 

the weighted-average number of common shares outstanding (the denominator) for the period. The computation of 
diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the 
number of additional common shares that would have been outstanding if the potentially dilutive common shares had 
been issued, calculated using the treasury stock method. 

The Company incurred a net loss for the year ended December 31, 2014, and has excluded 1,165,855 of 
incremental shares attributable to outstanding stock options and restricted stock units from the calculation of net loss per 
share because the effect would have been anti-dilutive.

(o)         Recent Accounting Guidance 

Accounting Standards or Updates Recently Adopted 

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 
(“ASU”) No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The amendments 
in this ASU require entities that present classified statements of financial position to classify deferred tax liabilities and 
assets as noncurrent. They apply to all entities that present a classified statement of financial position. For public 
business entities, the amendments in this ASU are effective for financial statements issued for annual periods beginning 
after December 15, 2016, and interim periods within those annual periods. The Company adopted ASU No. 2015-17 
early, effective June 30, 2016, on a prospective basis. As a result, the Company presented all deferred tax assets and 
liabilities as noncurrent on the consolidated balance sheet as of December 31, 2016, reducing current deferred tax assets 
by $0.2 million, long-term deferred tax assets by $0.3 million and short-term deferred tax liabilities by $0.5 million. The 
current deferred tax assets and liabilities on the consolidated balance sheet as of December 31, 2015, have not been 
reclassified. 

In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to 

Continue as a Going Concern.” ASU 2014-15 introduces an explicit requirement for management to assess if there is 
substantial doubt about an entity’s ability to continue as a going concern, and to provide related footnote disclosures in 
certain circumstances. In connection with each annual and interim period, management must assess if there is substantial 
doubt about an entity’s ability to continue as a going concern within one year after the issuance date. Disclosures are 
required if conditions give rise to substantial doubt. The adoption of this standard did not have a material impact on the 
Company’s consolidated financial statements.

Accounting Standards or Updates Not Yet Effective 

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which provides 

guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it 
transfers promised goods or services to customers in an amount that reflects the consideration to which the company 
expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU 2016-10, “Revenue 
from Contracts with Customers” (Topic 606): Identifying Performance Obligations and Licensing, which further clarifies 
performance obligations in a contract with a customer. In May 2016, the FASB issued ASU 2016-12, “Revenue from 
Contracts with Customers” (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides a more 
narrow interpretation of ASU No. 2014-09. These ASUs are effective for annual reporting periods beginning after 
December 15, 2017 and interim periods within those annual periods. The Company is currently assessing the potential 
impact the adoption of these standards will have on the financial statements. 

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory,” which changes 
the inventory measurement principles for entities using the first-in, first-out (FIFO) or average cost methods. For entities 
utilizing one of these methods, the inventory measurement principle will change from lower of cost or market to the 
lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of 
business, less the reasonably predictable costs of completion, disposal and transportation. The amendments are effective 
for annual and interim periods beginning after December 15, 2016. The adoption of this ASU will not have a material 
impact on the Company’s financial statements and disclosures. 

In February 2016, the FASB issued ASU No. 2016-02 “Leases.” The ASU requires lessees to recognize the 
rights and obligations created by most leases as assets and liabilities on their balance sheet and continue to recognize 
expenses on their income statement over the lease term. It will also require disclosures designed to give financial 
statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is 
effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early 
adoption is permitted for all entities. The Company is currently evaluating the impact of ASU 2016-02 on the 
consolidated financial statements and disclosures. 

In March 2016, the FASB issued ASU No. 2016-09 “Compensation — Stock Compensation,” which changes 

the accounting for stock-based payment transactions, including the income tax consequences, classification of awards as 
either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments 
in this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual 
periods. Early adoption is permitted for all entities and any entity that elects early adoption must adopt all of the 
amendments in the same period.  The adoption of this ASU will not have a material impact on the Company’s financial 
statements and disclosures. 

In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a 

consensus of the FASB Emerging Issues Task Force).” This ASU requires the statement of cash flows to explain the 
change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or 
restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents are 
to be included with cash and cash equivalents when reconciling the beginning of period and end of period amounts 
shown on the statement of cash flows.  ASU No. 2016-18 will be effective for annual reporting periods beginning after 
December 15, 2017. The adoption of this ASU will not have a material impact on the Company’s financial statements 
and disclosures. 

Note 3. Correction of Accounting Error in Prior Period 

Subsequent to March 31, 2016, but prior to filing the Form 10-Q for the quarter ended June 30, 2016, the 

Company discovered a cumulative error associated with the elimination of profits on sales of inventory to its 
subsidiaries.  This error had no impact upon the Company’s consolidated statement of operations or consolidated 
statement of cash flows subsequent to the year ended December 31, 2010.  The following financial statement line items 
reported in the Company’s consolidated balance sheet for the year ended December 31, 2015 was affected by the 
correction of this accounting error:

This error was associated with transactions occurring prior to September 2010, at which time the Company 

revised its methodology to compute and eliminate intercompany profits. However, the Company failed to identify and 
record an entry to eliminate the cumulative error resulting from the prior methodology. This $6.5 million error resulted in 
an overstatement of inventory and a cumulative understatement of cost of product revenue as of September 2010.  
Thereafter, the effect was an overstatement of inventory and understatement of accumulative deficit for each subsequent 
reporting period.  The consolidated balance sheets as of December 31, 2015 and 2014 have been revised to reflect the 
correction of the error through a decrease in inventory and an increase in accumulated deficit of $6.5 million.  In the 
opinion of management, the effect is not material to the consolidated financial position or results of operations for any 
previously reported period.   

Note 4. 1-for-4 Reverse Stock Split 

As of 6:00 PM Eastern Time on June 30, 2016, the Company effected a 1-for-4 reverse stock split of its 

common stock. The Company continues to be traded under its unchanged symbol “ACLS.” All previously reported 
common stock share amounts in the accompanying financial statements and related notes have been retroactively 
adjusted to reflect the reverse stock split. As a result of the reduced number of shares outstanding after the reverse stock 
split, the stated capital attributable to common stock on the Company’s balance sheet (which consists of the unchanged 
$0.001 par value per share multiplied by the aggregate number of shares issued and outstanding), has been reduced. 
Correspondingly, the Company’s additional paid-in capital account, which consists of the difference between its stated 
capital and the aggregate amount paid to the Company upon issuance of all currently outstanding shares of its common 
stock, has been credited with the amount by which the stated capital was reduced. The Company’s stockholders’ equity, 
in the aggregate, remains unchanged. 

Immediately prior to the effectiveness of the reverse stock split, the Company retired 30 thousand shares of 

common stock held in treasury to the status of authorized and unissued. 

Note 5. Restricted Cash 

The restricted cash of $6.9 million at December 31, 2016 relates to a $5.9 million letter of credit associated to 
the security deposit for the sale leaseback transaction, a $0.9 million letter of credit relating to workers’ compensation 
insurance and a $0.1 million deposit relating to customs activity. The change in restricted cash is classified in the 
statement of cash flows as a financing activity.

When recorded, inventory reserves are intended to reduce the carrying value of inventories to their market 

value. The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of 
anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market 
conditions. The Company regularly evaluates the ability to realize the value of inventories based on a combination of 
factors including the following: forecasted sales or usage, estimated product end of life dates, estimated current and 
future market value and new product introductions. Purchasing and usage alternatives are also explored to mitigate 
inventory exposure. In 2016, the Company recorded an overall decrease of $1.6 million in the inventory reserves, which 
consisted of disposals due to previously reserved for obsolescence and excess inventory of $2.6 million partially offset 
by a provision charge to the reserve of $1.0 million. As of December 31, 2016 and 2015, inventories are stated net of 
inventory reserves of $8.8 million and $10.5 million respectively. 

During each of the years ended 2016, 2015 and 2014, the Company recorded charges to cost of sales of $0.8 

million, $0.5 million and $0.8 million to reflect the lower of cost or market value. During 2014, the Company recorded a 
charge to cost of sales of $1.0 million due to production levels below normal capacity.

The Company generally offers a one year warranty for all of its systems, the terms and conditions of which vary 
depending upon the product sold. For all systems sold, the Company accrues a liability for the estimated cost of standard 
warranty at the time of system shipment and defers the portion of systems revenue attributable to the fair value of 
non-standard warranty. Costs for non-standard warranty are expensed as incurred. Factors that affect the Company’s 
warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and 
service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts the amount as 
necessary.

On January 30, 2015, the Company sold its corporate headquarters facility for the purchase price of $48.9 

million. As part of the sale, the Company also entered into a 22-year lease agreement with the buyer. The sale leaseback 
is accounted for as a financing arrangement for financial reporting and, as such, the Company recorded a financing 
obligation of $47.6 million as of December 31, 2016. The associated lease payments include both an interest component 
and payment of principal, with the underlying liability being extinguished at the end of the original lease term. The 
Company posted a collateralized security deposit of $5.9 million in the form of an irrevocable letter of credit at the time 
of the closing. Upon the termination of our credit facility with Silicon Valley Bank in October 2015, this letter of credit 
was cash collateralized.  

Note 13. Employee Benefit Plans 

(a)          Defined Contribution Plan 

The Company maintains the Axcelis Long-Term Investment Plan, a defined contribution plan. All regular 

employees are eligible to participate and may contribute up to 35% of their compensation on a before-tax basis subject to 
Internal Revenue Service (“IRS”) limitations. Highly compensated employees may contribute up to 16% of their 
compensation on a before-tax basis subject to IRS limitations. In 2015, the Company implemented a matching 
contribution of up to one thousand U.S. dollars on a dollar-for-dollar basis on contributions by eligible participants. In 
2016, the Company increased the matching contribution to a maximum of one thousand two hundred U.S. dollars, on the 
basis of one dollar matched for each two dollars contributed by eligible participants. Total related expense for 2016 and 
2015 was $0.4 million. 

(b)          Other Compensation Plans 

The Company operates in foreign jurisdictions that require lump sum benefits, payable based on statutory 
regulations, for voluntary or involuntary termination. Where required, an annual actuarial valuation of the benefit plans is 
obtained.

Note 14. Stock Award Plans and Stock Based Compensation 

(a)          Equity Incentive Plans 

The Company maintains the Axcelis Technologies, Inc. 2012 Equity Incentive Plan (the “2012 Equity Plan”), 
which became effective on May 2, 2012. Our 2000 Stock Plan (the “2000 Stock Plan”) expired on May 1, 2012 and no 
new grants may be made under that plan after that date. However, awards granted under the 2000 Stock Plan prior to the 
expiration remain outstanding and subject to the terms of the 2000 Stock Plan. 

The 2012 Equity Plan, as amended, reserves 5.5 million shares of common stock, $0.001 par value, for grant 
and permits the issuance of options, stock appreciation rights, restricted stock, restricted stock units, stock equivalents 
and awards of shares of common stock that are not subject to restrictions or forfeiture to selected employees, directors 
and consultants of the Company. Shares that are not issued under an award (because such award expires, is terminated 
unexercised or is forfeited) that were outstanding under the 2000 Stock Plan as of the May 2, 2012, increase the reserve 
of shares available for grant under the 2012 Equity Plan. 

The term of stock options granted under these plans is specified in the award agreements. Unless a lesser term is 

otherwise specified by the Compensation Committee of the Company’s Board of Directors, awards under the 2012 
Equity Plan will expire seven years from the date of grant. In general, all awards issued under the 2000 Stock Plan expire 
ten years from the date of grant. Under the terms of these stock plans, the exercise price of a stock option may not be less 
than the fair market value of a share of the Company’s common stock on the date of grant. Under the 2012 Equity Plan, 
fair market value is defined as the last reported sale price of a share of the common stock on a national securities 
exchange as of any applicable date, as long as the Company’s shares are traded on such exchange. 

Stock options granted to employees generally vest over a period of four years, while stock options granted to 

non-employee members of the Company’s Board of Directors generally vest over a period of six months and, once 
vested, are not affected by the director’s termination of service to the Company. In limited circumstances, the Company 
may grant stock option awards with market-based vesting conditions, such as the Company’s common stock price, or 
other performance conditions. Termination of service by an employee will cause options to cease vesting as of the date of 
termination, and in most cases, employees will have 90 days after termination to exercise options that were vested as of 
the termination of employment. In general, retiring employees will have one year after termination of employment to 
exercise vested options. The Company settles stock option exercises with newly issued common shares. 

Restricted stock units granted to employees during 2016 had both time-based vesting provisions and 

performance-based vesting provisions. Generally, unvested restricted stock unit awards expire upon termination of 
service to the Company. The Company settles restricted stock units upon vesting with newly issued common shares. No 
restricted stock was granted under either stock plan during the three year period ended December 31, 2016.

As of December 31, 2016, there were 0.7 million shares available for grant under the 2012 Equity Plan. No 

shares are available for grant under the 2000 Stock Plan. 

As of December 31, 2016, there were 5.0 million options outstanding under the 2012 Equity Plan and the 2000 

Stock Plan, collectively, and 0.5 million unvested restricted stock units outstanding under the 2012 Stock Plan. 

(b)          Employee Stock Purchase Plan 

The Employee Stock Purchase Plan (the “Purchase Plan”) provides effectively all of the Company’s employees 

the opportunity to purchase common stock of the Company at less than market prices. Purchases are made through 
payroll deductions of up to 10% of the employee’s salary as elected by the participant, subject to certain caps set forth in 
the Purchase Plan. Employees may purchase the Company’s common stock at 85% of its market on the day the stock is 
purchased. 

The Purchase Plan is considered compensatory and as such, compensation expense has been recognized based 

on the benefit of the discounted stock price, amortized to compensation expense over each offering period of six months. 
Compensation expense relating to the Purchase Plan was approximately $0.1 million for each of the years ended 
December 31, 2016, 2015 and 2014. 

As of December 31, 2016, there were a total of 0.3 million shares reserved for issuance and available for 

purchase under the Purchase Plan. Less than 0.1 million shares were purchased under the Purchase Plan in each of the 
years ended December 31, 2016, 2015 and 2014.  

(c)          Valuation of Stock Options and Restricted Stock Units 

For the purpose of valuing stock options with service conditions, the Company uses the Black-Scholes option 

pricing model to calculate the grant-date fair value of an award. The fair values of options granted were calculated using 
the following estimated weighted-average assumptions: 

Weighted-average expected volatility 
Weighted-average expected term 
Risk-free interest rate 
Expected dividend yield 

2016 
  49.3% — 56.7% 
4.7 years 
1.1% — 2.0% 
0% 

Year ended December 31,  
2015 

2014 

  56.2% — 64.7%    60.6% — 98.4%  
  4.6 — 4.7 years    3.8 — 4.7  years  
  1.2% — 1.7%   
  1.3% — 1.6% 
0% 

0% 

Expected volatility—The Company considers a number of factors when estimating volatility for stock options 

granted. The Company’s method of estimating expected volatility relies on a combination of historical and implied 
volatility. The Company believes that this blended volatility results in an accurate estimate of the grant-date fair value of 
employee stock options because it appropriately reflects the market’s current expectations of future volatility. 

Expected term—The Company calculated the weighted average expected term for stock options granted prior to 

July 1, 2012, using a forward looking lattice model of the Company’s stock price incorporating a suboptimal exercise 
factor and a projected post-vest forfeiture rate. For stock options granted after July 1, 2012 to employees and to 
non-employee members of the Company’s Board of Directors, the Company used the simplified method for estimating 
the expected life of “plain vanilla” options because it did not have sufficient exercise history to use a lattice model. The 
Company expects that it will use a lattice model once sufficient exercise history has been established. A change in the 
contractual life from 10 years to 7 years was made to reflect the fact that options granted after May 1, 2012 were granted 
under the 2012 Equity Incentive Plan, which limits option terms to seven years. 

Risk-free interest rate - The yield on zero-coupon U.S. Treasury securities for a period that is commensurate 

with the expected term assumption is used as the risk-free interest rate.

Expected dividend yield—Expected dividend yield was not considered in the option pricing formula since the 

Company does not pay dividends and has no current plans to do so in the future. 

In limited circumstances, the Company also issues stock option grants with vesting based on market conditions, 

such as the Company’s common stock price, or a combination of time or market or performance conditions. The fair 
values and derived service periods for all grants that have vesting based on market or performance conditions are 
estimated using the Monte Carlo valuation method. For each stock option grant with vesting based on a combination of 
time and performance or market conditions, where vesting will occur if either condition is met, the related compensation 
costs are recognized over the shorter of the explicit service period or the derived service period. 

The fair value of the Company’s restricted stock units is calculated based upon the fair market value of the 

Company’s stock at the date of grant. 

(d)          Summary of Stock-based Compensation Expense 

The Company uses the straight-line attribution method to recognize expense for stock-based awards such that 

the expense associated with awards is evenly recognized throughout the period. 

The amount of stock-based compensation recognized is based on the value of the portion of the awards that are 

ultimately expected to vest. The Company estimates forfeitures at the time of grant and revises them, if necessary, in 
subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” 
or “expirations” and represents only the unvested portion of the surrendered stock-based award. Based on a historical 
analysis, a forfeiture rate of 5% per year was applied to stock-based awards, including executive officer awards, for the 
years ended December 31, 2016, 2015 and 2014. 

For the year ended December 31, 2016, the Company recognized stock-based compensation expense of $5.2 
million. Stock-based compensation expense was $5.6 million and $4.8 million for the years ended December 31, 2015 
and 2014, respectively. The Company presents the expenses related to stock-based compensation in the same expense 
line items as cash compensation paid to its employees. For the year ended December 31, 2016, the Company primarily 
used restricted stock units in its annual equity compensation program. For the years ended December 31, 2015 and 2014, 
the Company primarily used stock options in its annual equity compensation program. 

The benefit of tax deductions in excess of recognized compensation cost is reported as a financing cash flow, 

rather than as an operating cash flow. Because the Company does not recognize the benefit of tax deductions in excess of 
recognized compensation cost due to its cumulative net operating loss position, this had no impact on the Company’s 
consolidated statement of cash flows as of and for the years ended December 31, 2016, 2015 or 2014.

(1)  In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the 
future. Options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options. 

The total intrinsic value, which is defined as the difference between the market price at exercise and the price 

paid by the employee to exercise the options, for options exercised during the years ended December 31, 2016, 2015 and 
2014 was $2.5 million, $5.3 million and $2.4 million, respectively. 

The total fair value of stock options vested during the years ended December 31, 2016, 2015 and 2014 was 

$3.9 million, $5.4 million and $4.7 million respectively. The weighted average grant-date fair value of options granted 
for the years ended December 31, 2016, 2015 and 2014 was $5.75, $5.05 and $3.82, respectively. As of December 31, 
2016, there was $4.8 million of total forfeiture-adjusted unrecognized compensation cost related to non-vested stock 
options granted under the 2012 Equity Incentive Plan and the 2000 Stock Plan. That cost is expected to be recognized 
over a weighted-average period of 2.1 years. 

(f)          Restricted Stock and Restricted Stock Units 

Restricted stock units (“RSUs”) represent the Company’s unfunded and unsecured promise to issue shares of 

the common stock at a future date, subject to the terms of the RSU Award Agreement in either the 2012 Equity Incentive 
Plan or the 2000 Stock Plan. The purpose of these awards is to assist in attracting and retaining highly competent 
employees and directors and to act as an incentive in motivating selected employees and directors to achieve long-term 
corporate objectives. RSU awards granted in 2016 included time vested share awards and awards with performance 
vesting conditions. No restricted stock awards were granted, or vested, during the years ended December 31, 2016, 2015 
and 2014.  The fair value of a restricted stock unit and restricted stock award is charged to expense ratably over the 
applicable service period.

The Company may issue up to 30 million shares of preferred stock in one or more series. The Board of 
Directors is authorized to fix the rights and terms for any series of preferred stock without additional shareholder 
approval. As of December 31, 2016 and 2015, there were no outstanding shares of preferred stock. 

Note 16. Fair Value Measurements 

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 

exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market 
participants on the measurement date. 

(a)          Fair Value Hierarchy 

The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs 

and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy 
based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial 
instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the 
fair value measurement. The fair value hierarchy is as follows: 

Level 1—applies to assets or liabilities for which there are quoted prices in active markets for identical 

assets or liabilities. 

Level 2—applies to assets or liabilities for which there are inputs other than quoted prices that are 
observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; 
quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions 
(less active markets); or model-derived valuations in which significant inputs are observable or can be derived 
principally from, or corroborated by, observable market data. 

Level 3—applies to assets or liabilities for which there are unobservable inputs to the valuation 

methodology that are significant to the measurement of the fair value of the assets or liabilities.

(b)          Assets and Liabilities Measured at Fair Value 

The Company’s money market funds are included in cash and cash equivalents in the consolidated balance 

sheets, and are considered a level 1 investment as they are valued at quoted market prices in active markets. The 
Company’s sale leaseback obligation relating to the sale of our corporate headquarters is carried at amortized cost, which 
approximates fair value based on an implied borrowing rate of 10.65%. The underlying cash flow associated with our 
lease payments is being applied to both an interest and principal component using the effective interest method over the 
associated lease term. The liability is categorized as level 3 within the fair value hierarchy.  

The following table sets forth Company’s assets and liabilities which are measured at fair value by level within 

the fair value hierarchy.

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents (which are 
comprised primarily of money market funds and deposit accounts), accounts receivable, prepaid expenses and other 
current and non-current assets, restricted cash, accounts payable and accrued expenses approximate fair value due to their 
short-term maturities. 

Note 17. Commitments and Contingencies

At December 31, 2016, the Company had $124.0 million of deferred tax assets worldwide relating to net 

operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce 
income taxes in future years. A valuation allowance must be established when it is “more likely than not” that all or a 
portion of deferred tax assets will not be realized. A review of all available positive and negative evidence needs to be 
considered, including a company’s performance, the market environment in which the company operates, length of 
carryback and carryforward periods, existing sales backlog, and projections of future operating results. Where there are 
cumulative losses in recent years there is a strong presumption that a valuation allowance is needed. This presumption 
can be overcome in very limited circumstances. 

The Company maintains a valuation allowance reducing the carrying value of the deferred tax assets in the 

United States to zero. The Company will continue to maintain a full valuation allowance for those tax assets until 
sustainable future levels of profitability are evident. Changes in the valuation allowance in 2016 and 2015 were 
attributable to changes in the composition of temporary differences and changes in net operating loss carryforwards. The 
remaining net deferred tax asset on the consolidated balance sheet represents the balances related to the activities of the 
foreign subsidiaries. 

At December 31, 2016, the Company has federal and state net operating loss carryforwards of $317.1 million 

and foreign net operating loss carryforwards of $2.8 million, expiring principally between 2017 and 2034. 

The Company has research and development and other tax credit carryforwards of $12.8 million at December 
31, 2016 that can be used to reduce future federal and state income tax liabilities. These tax credit carryforwards expire 
principally between 2017 and 2028. The Company does not have any foreign tax credit carryforwards as a result of the 
expiration of $3.6 million of foreign tax credits at December 31, 2016. 

It is Company policy to provide taxes for the total anticipated tax impact of the undistributed earnings of our 

wholly-owned foreign subsidiaries, as such earnings are not expected to be reinvested indefinitely. The Company 
anticipates that U.S. tax resulting from remitting such earnings will be offset by net operating loss or credit carryforwards 
to the extent available. In addition, the Company does not anticipate incurring a foreign withholding tax on remitting 
such earnings since it does not intend to remit the earnings as dividends. 

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and 

foreign jurisdictions. The Company and most foreign subsidiaries are subject to income tax examinations by tax

authorities for all years dating back to 2005. The Company’s policy is to recognize interest related to unrecognized tax 
benefits as interest expense and penalties as operating expenses. The Company believes that it has appropriate support 
for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for 
all open years based on an assessment of many factors including past experience and interpretations of tax law applied to 
the facts of each matter. 

At December 31, 2016, the Company had unrecognized tax benefits related to uncertain tax positions of 

approximately $6.8 million, of which approximately $5.4 million reduced the Company’s deferred tax assets and the 
offsetting valuation allowance and $1.5 million was recorded in other long-term liabilities. During the first quarter of 
2016, the statute of limitations associated with a tax position previously taken by the Company expired. The related tax 
reserve of $0.6 million and accrued interest of $0.3 million that had been recorded were reversed during the twelve 
months ended December 31, 2016. The Company believes that it is reasonably possible that there will be a reduction to 
the reserve for uncertain tax positions of approximately $0.5 million within the next twelve months as a result of the 
expiration of the statute of limitations in a foreign tax jurisdiction. The Company recognized $0.2 million in interest and 
penalty expense related to unrecognized tax benefits for each of the years-ended December 31, 2016, 2015 and 2014, 
respectively. 

A reconciliation of the beginning and ending balance of unrecognized tax benefits are as follows: 

Balance at beginning of year 
Increase (decrease) in unrecognized tax benefits as a result of tax 
positions taken during a prior period 
Decreases in unrecognized tax benefits related to settlements with tax 
authorities 
Reductions to unrecognized tax benefits as a result of a lapse of the 
applicable statute of limitation 
Increases in unrecognized tax benefits as a result of tax positions taken 
during the current period
