To Our Shareholders and Employees:

In 2017, Endologix® remained exclusively focused on safely expanding the treatment possibilities 

of aortic care. We believe we are the only company to provide a portfolio of devices that allows 

physicians to tailor solutions to each patient’s unique aortic anatomy.

During the year, we saw 40%+ global growth from our Ovation® Stent Graft 

System while making important improvements in the manufacturing process 

for our AFX® and AFX®2 devices. We also collaborated with the FDA to gain 

approval for a confirmatory IDE clinical study to evaluate the Nellix® Gen2 

device together with the refined indications for use. Recently, we completed 

enrollment in the ELEVATE IDE clinical study to evaluate the safety and 

effectiveness of the Alto™ Stent Graft System, our newest device, which is 

expected to be introduced in the U.S. and Europe in 2019.    

As a technological pioneer, Endologix has experienced challenges bringing new 

clinical improvements to market over the past few years. The lessons we’ve 

learned while overcoming these challenges are now being integrated into the 

design of our new devices, along with improved patient selection, procedure 

techniques and physician training. Additionally, we continue to make significant 

investments in our quality systems to ensure our devices provide exceptional 

quality and reliability to physicians and patients worldwide.

Over the past six months, we have strengthened our leadership team with the additions of  

John Onopchenko, Chief Operating Officer; Jeremy Hayden, General Counsel; and Greg Morrow, 

Chief Marketing Officer. We believe these experienced and dedicated executives, together with 

the existing leadership team, are well positioned to take Endologix into the future. As you know, 

I will be stepping down as CEO but will continue to support Endologix until a new CEO is 

appointed in order to ensure a smooth transition. It has been a privilege to work with so many 

talented employees and physicians over the past decade, and I wish Endologix great success  

in the years ahead.

Endologix is uniquely positioned to significantly improve clinical outcomes for aortic patients. We 

believe our broad portfolio of innovative technologies and unwavering commitment to quality will 

be a winning formula for employees, shareholders, physicians and patients. 

Sincerely, 

John McDermott 

Chief Executive Officer

Business 

Company Overview

PART I

We develop, manufacture, market, and sell innovative medical devices for the treatment of aortic disorders. Our products 

are intended for the minimally invasive endovascular treatment of abdominal aortic aneurysms ("AAA"). Our AAA products 
are built on one of two platforms: 

•  Traditional minimally-invasive endovascular aneurysm repair (“EVAR”) or 

•  Endovascular aneurysm sealing (“EVAS”), our innovative solution for sealing the aneurysm sac while maintaining 

blood flow through two blood flow lumens. 

Our current EVAR products include the AFX® Endovascular AAA System (the “AFX System”), the VELA® Proximal 

Endograft (“VELA”), and the Ovation® Abdominal Stent Graft System (the “Ovation System”). Our current EVAS product is 
the Nellix® Endovascular Aneurysm Sealing System (the “Nellix EVAS System”). We sell our EVAR platforms (including 
extensions and accessories) to hospitals in the United States, Canada, New Zealand, South Korea and Europe, and our EVAS 
platform to hospitals in New Zealand and Europe. We sell our EVAR and EVAS platforms (including extensions and 
accessories) to third-party international distributors and agents in Asia, Europe, South America and in other parts of the world. 
Such sales of our EVAR and EVAS platforms provide the sole source of our reported revenue.

Endologix®, AFX®, Nellix®, IntuiTrak®, Ovation®, VELA®, Ovation Prime®, Duraply®, Ovation Alto®, and CustomSeal®, 
are registered trademarks of Endologix, Inc. and its subsidiaries. ActiveSeal™ and the respective product logos are trademarks 
of Endologix, Inc. and its subsidiaries. 

We have obtained CE Mark approval for the Nellix EVAS System in the European Union. The Nellix EVAS System is 
only approved as an investigational device in the United States. Ovation Alto, our next generation Ovation System device, is 
only approved as an investigational device and is not currently approved in any market.

Our Mission

Our mission is to be the leading innovator of medical devices to treat aortic disorders. The key elements of our strategy to 

accomplish this mission are as follows:

• 
• 

• 
• 

• 

Focus exclusively on the aorta for the commercialization of innovative products.
Design and manufacture EVAR and EVAS products that are easy to use and deliver excellent clinical 
outcomes.
Design EVAR and EVAS products to expand into the treatment of complex AAA and thoracic anatomies.
Offer physicians and hospitals a broad range of products so they can provide the best device for each 
individual patient.
Provide exceptional clinical and technical support to physicians through an experienced and knowledgeable 
sales and clinical organization.

Market Overview and Opportunity

AAA Background 

Atherosclerosis reduces the integrity and strength of blood vessel walls, causing the blood vessel to expand or balloon 
out, which is known as an “aneurysm”. Aneurysms are commonly diagnosed in the aorta, which is the body’s largest artery, 
extending from the chest to the abdomen. The abdominal aorta is the segment between the renal (kidney) arteries and the area 
where the aorta divides into the two iliac arteries which travel down the legs. An abdominal aortic aneurysm (“AAA”) occurs 
when a portion of the abdominal aorta bulges into an aneurysm because of a weakening of the vessel wall, which may result in 
life threatening internal bleeding upon rupture. AAA is more common in men than women. 

Although AAA is one of the most serious cardiovascular diseases, many AAAs are never detected. Most AAA patients do 

not have symptoms at the time of their initial diagnosis. AAAs generally are discovered coincidentally during procedures to 
treat or diagnose unrelated medical conditions.

According to a paper titled Elective Versus Ruptured Abdominal Aortic Aneurysm Repair: A 1-Year Cost-Effectiveness 

Analysis, the overall patient mortality rate for ruptured AAA is approximately 80%, making it among the leading causes of 

2

death in the United States. Once diagnosed, patients with AAA require either non-invasive monitoring, or, depending on the 
size and rate of growth of the AAA, EVAR, EVAS or open surgical repair.

 EVAR and EVAS Versus Open Surgical Repair

Our EVAR and EVAS products are used exclusively for minimally-invasive procedures, as opposed to open surgical 

repair of AAA. Open surgical repair is a highly invasive procedure requiring (i) a large incision in the patient’s abdomen, (ii) 
manipulation of the patient’s abdominal organs to gain access to the aneurysm, (iii) the cross clamping of the aorta to stop 
blood flow, and (iv) implantation of a synthetic graft which is sutured to the aorta, connecting one end above the aneurysm, to 
the other end below the aneurysm. 

Open surgical repair typically lasts for two to four hours, while the typical EVAR and EVAS procedure lasts for one to 
two hours. After receiving open surgical repair, a patient usually requires a few days in the hospital’s surgical intensive care 
unit, and the total hospital stay may be four to ten days. Post-procedure convalescence may take another four to six weeks due 
to the invasiveness of the operation. By comparison, patients are often discharged a day or two after their EVAR and EVAS 
procedure, and once discharged, most patients return to normal activity within two weeks.

We estimate that approximately 75% of all treated AAAs in the United States are repaired through EVAR, and 25% 

through open surgical repair. Although EVAR and EVAS have many advantages over open surgical repair, many patients are 
not candidates for EVAR and EVAS due to the limitations of current EVAR devices to treat more complex AAA anatomies. We 
are developing new products to address these more challenging anatomies.

 Market Size

We estimate the global endovascular aortic aneurysm market potential to be $4.0 billion annually. Of this amount, we 

estimate the traditional aneurysm market potential, encompassing aneurysms with aortic neck length greater than or equal to 
10mm, to be $1.6 billion. The majority of diagnosed aneurysms in this market can be treated with currently available EVAR 
products. We estimate that a $1.2 billion market opportunity exists for the treatment of challenging anatomies, defined as 
aneurysms with neck lengths less than 10mm. Currently, there are limited options with available EVAR products to treat these 
short or no neck aortic aneurysms. The thoracic aneurysm market includes aneurysms, dissections, and transections in the 
ascending aorta, the aortic arch, and the descending aorta. For many of these anatomies there are limited endovascular options 
due to anatomical and technological challenges. We believe the thoracic market potential is $1.2 billion. Below is a table 
summarizing the market potential and penetration by aneurysm type.

We estimate that there are approximately 202,300 AAA (EVAR and surgical repair) procedures performed across the 

globe annually.

In the United States alone, an estimated 1.2 million to 2.0 million people have an AAA and over 200,000 people are 

diagnosed with an AAA in the United States annually. Of those diagnosed with an AAA, approximately 60,000 people 
underwent an AAA repair procedure in the United States in 2017, of which approximately 46,000 were addressed through 
EVAR.

According to United States Census Bureau estimates, the age 65 and over population in the United States presently 
numbers approximately 51 million, or 16% of the total population, and is expected to grow by 3.4% annually to 56 million by 
2020. Accordingly, we believe that AAA treatments will naturally increase over time, given this demographic trend.

         Since AAAs generally arise in people over the age of 65 and come with little warning, initiatives have been undertaken to 
increase screening. The most prominent of these initiatives is the Screening Abdominal Aortic Aneurysms Very Efficiently Act 
(“SAAAVE”), which was signed into law in the United States on February 8, 2006, began providing coverage on January 1, 
2007 and was updated effective January 1, 2014. SAAAVE provides for a one-time free AAA screening for men who have 
smoked some time in their life, and men or women who have a family history of the disease.

Our Products

       Our EVAR Platforms

AFX System and VELA:
The AFX System consists of (i) a cobalt chromium alloy stent covered by expanded polytetrafluoroethylene (commonly 

referred to as ePTFE) graft material and (ii) accompanying delivery systems. Once fixed in its proper position within the 
abdominal aortic bifurcation, the AFX System provides a conduit for blood flow, thereby relieving pressure within the 
weakened or “aneurysmal” section of the vessel wall, which greatly reduces the potential for the AAA to rupture. In February 
2014, we launched a new proximal extension in the United States, VELA, designed to be used in conjunction with our AFX 
bifurcated device. VELA features a circumferential graft line marker and controlled delivery system that enable predictable 
deployment and final positional adjustments. We began a commercial introduction of VELA in Europe in January 2015.

• 

• 

• 

Anatomical Fixation. The AFX System is unique in that the main body of the device sits on the patient's 
natural aortoiliac bifurcation. This provides a solid foundation for the long-term stability of the device.  
Alternative EVAR devices rely on hooks, barbs and radial force to anchor within the aorta (commonly 
referred to as "proximal fixation") near the renal arteries. The data from our clinical studies have 
demonstrated anatomical fixation can inhibit device migration within the aorta due to the inherent 
foundational support of the patient’s own anatomy.

Minimally Invasive Delivery System. The AFX System requires 17F introducer access on the ipsilateral side 
and 7F introducer access on the contralateral side. Comparative endovascular stent grafts for infrarenal 
repair require between 12F and 22F introducer access on the ipsilateral side and between 10F and 16F 
introducer access on the contralateral side.

Preserves Aortic Bifurcation. The AFX System allows for future endovascular procedures when access 
across the aortic bifurcation is required. Approximately 30% to 40% of AAA patients also have peripheral 
arterial disease (“PAD”). The AFX System is the only graft presently available that preserves the 
physician's ability to go back over the aortic bifurcation for future interventions. This is a meaningful 
feature of the AFX System, as many AAA patients today are living longer and returning to the hospital for 
PAD procedures.

Ovation System:
The Ovation System consists of (i) a radiopaque nitinol suprarenal stent with integral anchors, (ii) a low-permeability 

polytetrafluoroethylene (“PTFE”), aortic body graft that contains a network of inflatable rings filled with a liquid polymer that 
solidifies during the deployment procedure, (iii) nitinol iliac limb stents encapsulated with PTFE, and (iv) accompanying ultra-
low profile delivery systems, auto injector and fill polymer kit. The Ovation System creates a custom seal that conforms to 
anatomical irregularities and has a low profile delivery system allowing for percutaneous access.

• 

• 

• 

• 

Patient Accessibility. Our FDA and CE Mark-approved Instructions for Use (“IFU”) allow for the on-label 
treatment of more patients who otherwise may undergo an off-label EVAR procedure or be subject to open 
surgical repair, or not receive treatment at all. Our differentiated platform expands the pool of patients 
eligible for EVAR by virtue of its low profile and flexible delivery system that addresses several key 
anatomical access challenges, while providing a novel sealing mechanism to address many of the 
difficulties of diseased patient anatomies. 
Ability to Pass through Small Access Vessels. The Ovation System’s novel separation and optimization of 
fixation and seal minimize the overlap between metal and fabric within the catheter, allowing the device to 
be loaded in a delivery catheter that is smaller than those of conventional EVAR devices. At an outer 
diameter of 14F, or approximately 4.7mm, the Ovation System is the lowest profile FDA-approved stent 
graft.
Ability to Pass through Diseased and/or Tortuous Access Vessels. The Ovation System has the lowest 
profile FDA-approved delivery system. Its characteristics increase flexibility, designed to enable easier 
passage through access vessels. 

The Ovation System Enables Minimally Invasive Techniques. The Ovation System’s low profile and proven 
safety record offer physicians the opportunity to provide percutaneous endovascular aneurysm repair 
access (“PEVAR”) with regional or local anesthesia to more patients. Studies have shown that the use of 
smaller profile delivery devices results in fewer access site complications.

4

• 

• 

Treatment of Complex Anatomy. The separation and optimization of the fixation and sealing mechanisms of 
the Ovation System enable the device to seal with a smaller aortic contact area than conventional EVAR 
devices. 

Avoiding Aortic Neck Dilatation. The Ovation System’s polymer filled sealing rings do not exert significant 
chronic, outward pressure at the` neck of the aorta. In the Ovation Pivotal Trial, core lab results 
demonstrated stable neck diameter and durable seal with the Ovation System through five-year follow-up.

Our EVAS Platform

Nellix EVAS System:

Our Nellix EVAS System is designed to seal the aneurysm and provide blood flow to the legs through two blood flow 
lumens. The Nellix EVAS System consists of (i) bilateral covered stents with endobags, (ii) a biocompatible polymer injected 
into the endobags to seal the aneurysm and (iii) a delivery system and associated accessories. The Nellix EVAS System is 
intended to seal the entire aneurysm sac effectively excluding the aneurysm and reducing the likelihood of future aneurysm 
rupture.

• 

• 

Potentially Reduce Endoleaks Leading to Secondary Interventions. The Nellix EVAS System seals the 
entire aneurysm, potentially reducing the likelihood of many causes of secondary intervention in EVAR 
procedures. 

Low Profile Introducer. The delivery catheter for the Nellix EVAS System has an outer diameter of 17F, 
which is beneficial for the delivery of the devices in tight access arteries, potentially reducing risk of 
vascular injuries to the patient.

Our EVAR and EVAS Extensions and Accessories

Aortic Extensions and Limb Extensions. We offer limb extensions for the Ovation System and proximal aortic extensions 

and limb extensions for the AFX System which allow physicians to customize the implant to fit the patient's anatomy. In 
February 2014, we launched a proximal extension in the United States, VELA, designed specifically for the treatment of 
proximal aortic neck anatomies with AFX. VELA features a circumferential graft line marker and controlled delivery system 
that enable predictable deployment and final positional adjustments. We commenced commercial sales of VELA in 2015. 

Accessories. We offer various accessories to facilitate the delivery of our EVAR and EVAS products, including 

compatible guidewires, inflation devices and snares. 

Our Product Evolution

     We first commercialized the Powerlink System (the "Powerlink System for AAA") in Europe in 1999 and in the United 

States in 2004. As our EVAR platform products evolved, we branded them under the names Powerlink System with Visiflex 
Delivery System, IntuiTrak®, and AFX. We added the Nellix EVAS System through our merger with Nellix, Inc. in December 
2010. We added the Ovation System to our EVAR product portfolio through our merger with TriVascular in February 2016.

• 
• 

• 

• 

• 

Powerlink System for AAA. The Powerlink System for AAA was our original EVAR product. 
IntuiTrak. We received FDA approval for IntuiTrak in October 2008, CE Mark approval for IntuiTrak in 
March 2010, and Japanese Shonin approval for IntuiTrak in December 2012. IntuiTrak provided an updated 
delivery system that enhanced physician ease of use and for manufacturability.
AFX. In May 2011 and November 2011, we received FDA approval and CE Mark approval, respectively, for 
the AFX System, and we received Japanese Shonin approval for the AFX System in December 2015. We 
began a full commercial launch of the AFX System in the United States in August 2011 and in numerous 
international markets in 2012. In addition, we entered into a distribution arrangement with a Japanese 
distributor to introduce the AFX System in the Japanese market in the first quarter of 2016.

AFX2. In October 2015, we received FDA approval for our AFX2 Bifurcated Endograft System (“AFX2”).

Ovation TriVascular. We received CE mark approval for the Ovation System in August 2010 and FDA 
approval for the Ovation System in October 2012. In February 2015, the FDA approved our next generation 
Ovation iX Iliac Stent Graft for the Ovation System, and in July 2015, the FDA approved the Ovation

• 

• 

iX Abdominal Stent Graft System.  In September 2015, the first patients were treated with the Ovation 
iX Abdominal Stent Graft System in Europe, and in October 2015, we initiated the launch of our Ovation iX 
Iliac Stent Graft System in the United States.

Nellix EVAS System. In February 2013, we received CE Mark approval of the Nellix EVAS System, and we 
commenced a limited market introduction of the Nellix EVAS System in Europe. In December 2013, we 
received IDE approval in the United States to begin a clinical trial which commenced in January 2014. 
Enrollment in the IDE study was completed in November 2014. In the fourth quarter of 2014, we obtained 
IDE continued access approval for additional patients. In April 2016, we announced achievement of CE Mark 
approval of the next-generation Nellix EVAS System. In September 2017, we announced CE Mark approval 
for the Nellix EVAS System with the refined IFU. In October 2017, we received IDE approval in the United 
States to begin the EVAS2 confirmatory clinical study to evaluate the next-generation Nellix EVAS System.

ChEVAS. ChEVAS is a procedure where the Nellix EVAS System could potentially be used together with 
branch stent grafts to treat patients with complex aortic anatomies. Physicians initiated a clinical trial called 
ASCEND (Aneurysm Study for Complex AAA: Evaluation of Nellix Durability) to evaluate the clinical 
performance of ChEVAS. We are pursuing CE mark and FDA approval for this indication.

Product Developments and Clinical Trials

Overview

We incurred expenses of $34.0 million in 2017, $48.6 million in 2016, and $41.8 million in 2015, on research and 
development activities and clinical studies. Our focus is to continually develop innovative and cost-effective medical devices 
for the treatment of aortic disorders. We believe that our ability to develop new technologies is a key to our future growth and 
success. Historically, we have focused on developing our EVAR and EVAS products to treat infrarenal AAA, including initial 
development of products to treat complex AAA anatomies. However, we expect to devote more resources in the future to 
developing, enhancing and obtaining expanded indications for our current EVAR and EVAS products and to develop new 
product indications to treat more complex anatomies. 

Nellix EVAS System

Using the technology we acquired in the Nellix acquisition, we developed the Nellix EVAS System, a next-generation 

device, to treat infrarenal AAA. We have the following trials in process to build independent and collective clinical and 
economic evidence of clinical safety and effectiveness:

•  EVAS FORWARD IDE - We conducted this pivotal clinical trial to evaluate the safety and effectiveness of the 

Nellix EVAS System. This study is a prospective single arm registry which enrolled 179 patients at 29 centers in 
the United States and Europe. In November 2014, we completed enrollment in the study, and we submitted the 
one year results to the FDA in March 2016. In May 2016, we announced the results of the one year clinical data 
from the EVAS FORWARD IDE study that demonstrate that the Nellix EVAS System met the study primary 
endpoints for major adverse events at 30 days (safety) and treatment success at one year (effectiveness). Two-
year imaging revealed a signal of migration, leading to a field safety notification issued in October 2016 and a 
dedicated root cause analysis, resulting in refinements to the IFU. Following the implementation of the refined 
IFU, the Nellix EVAS system is applicable to treat an estimated 40% of AAA patients with a traditional 
aneurysm.

Subsequently, the two-year results from the trial were announced. Key highlights from the Nellix US IDE trial 
two-year clinical data are included below:

•  Freedom from all endoleaks (94%), rupture (97%), all-cause mortality (97%), and cardiovascular mortality 

(99%), among all patients.

•  Highest freedom of type II endoleaks, of 97%, ever reported at two years, among all patients.

•  When applying the refined IFUs for Nellix, patients at the two-year follow-up demonstrated 96% freedom 

from Type IA endoleak, migration >10mm, and sac growth.

•  EVAS2 IDE - In May 2017, we announced the decision to seek United States approval of the Nellix EVAS 

System by conducting a confirmatory clinical study with the updated IFU and the Gen2 device design. The Gen2 
device incorporates design improvements to enhance ease of use and offers physicians more sizes to treat more 
patients with AAA. In October 2017, we announced our receipt of IDE approval from the FDA to commence a 
confirmatory clinical study to evaluate the safety and effectiveness of the Gen2 Nellix EVAS System for the 

6

endovascular treatment of infrarenal AAA. The EVAS2 IDE Multicenter Safety and Effectiveness Confirmatory 
Study (“EVAS2”) will prospectively evaluate the refined IFU and the Nellix Gen2 EVAS System. The study is 
approved to enroll up to 90 primary patients, with one-year follow-up data required for the pre-market approval 
(“PMA”) application. We commenced EVAS2 patient enrollment in March 2018, and currently estimate a 
decision on our PMA application by the end of 2020.

•  EVAS FORWARD Global Registry - This study is designed to provide real world clinical results to demonstrate 
the effectiveness and applicability of the Nellix EVAS System. The first phase of the registry included 300 
patients enrolled in up to 30 international centers. The first patient in the registry was treated in October 2013. In 
September 2014, we announced completion of patient enrollment in the EVAS FORWARD Global Registry. In 
November 2016, we announced positive two-year results on 300 patients from the EVAS FORWARD Global 
Registry at the annual VEITH meeting. The following outcomes were presented at the annual VEITH meeting: 

37% of the patients had complex anatomies;
98% freedom from any persistent endoleaks at latest follow-up;

• 
• 
•  No secondary interventions for Type II endoleaks;
• 
• 

97% freedom from aneurysm-related mortality; and
99% freedom from cardiovascular mortality.

In 2017, the EVAS FORWARD Global Registry 2 commenced a post market evaluation of the Nellix Gen2 
EVAS System, our second generation device design.

•  ASCEND Registry - In April 2016, we announced the first data presentation with one-year outcomes from the 

ASCEND Registry (Aneurysm Study for Complex AAA: Evaluation of Nellix Durability), a physician-initiated 
registry of the Nellix EVAS System used with aortic branch stent grafts for the treatment of patients with 
complex AAAs. The results of the study were formally published in the peer-reviewed Journal of Endovascular 
Therapy in December 2017.

Refined IFU - In September 2017, we announced CE Mark approval for the Nellix EVAS System with the refined IFU. 
The Nellix EVAS System is being studied in the U.S. under an IDE. Following a thorough review of supporting clinical data, 
the Company's Notified Body in the European Union, together with an independent clinical reviewer, has determined that the 
Nellix EVAS System, with the refined IFU, meets the applicable safety and clinical performance requirements. As a result of 
these evaluations, the Notified Body has granted a CE Mark for the Nellix EVAS System with the refined IFU.

AFX System

In September 2014, we announced a new clinical study called LEOPARD (Looking at EVAR Outcomes by Primary 
Analysis of Randomized Data). This study was designed to compare outcomes of the AFX System versus other commercially 
available EVAR devices. We designed the LEOPARD study to randomize and enroll up to 600 patients at 60 leading centers 
throughout the United States and commenced enrollment in the first quarter of 2015. The centers were a mix of our current and 
new customers, with each investigator selecting one competitive device to randomize against AFX. The LEOPARD study is 
being led by an independent steering committee of leading physicians who are involved with the study and responsible for 
presenting the results over the five-year follow-up period.

Subsequently, positive interim results from LEOPARD were announced. Based upon the patients that have completed 
their one-year follow-up, freedom from Aneurysm Related Complications with AFX/AFX2 is 84.7%, compared to 82.0% with 
other devices. These preliminary results demonstrate similar outcomes between the endografts under investigation. AFX/AFX2, 
however, remains the only device that preserves the patient's aortic bifurcation. Based upon the anticipated number of 
additional patients required to prove superiority, we stopped further randomization in the LEOPARD study and plan to continue 
to follow enrolled patients for the planned five years.

In December 2015, we announced that the AFX Endovascular AAA System for the treatment of AAA received Shonin 

approval from the Japanese Ministry of Health, Labor and Welfare (“MHLW”).

In February 2016, we announced the completion of the first United States commercial implant of AFX2, which reduces 

procedure steps for the delivery and deployment of the bifurcated endograft. AFX2 also facilitates PEVAR by providing the 
lowest profile contralateral access through a 7F introducer. These improvements bring together our ActiveSeal™ technology, 
DuraPly® PTFE graft material and VELA Proximal Endograft, into an integrated new EVAR system.

7

In December 2016, we received notice from our Notified Body in the European Union that the CE Mark for AFX and 

AFX2 would be suspended due to reports of Type III endoleaks with a prior generation of the device. We had, for our current 
generation of AFX products, implemented device and graft material improvements and updated IFUs resulting in a substantial 
reduction in reported Type III endoleaks. We provided documentation of the foregoing reduction in Type III endoleaks to our 
Notified Body.  In January 2017, we received notice from our Notified Body that the CE Mark for AFX and AFX2 had been re-
instated, effective immediately.  

Additionally, in December 2016, we placed a temporary hold on shipments of AFX and AFX2 to complete an 

investigation of quality concerns with some sizes of these devices. Subsequently, we removed the temporary hold and resumed 
shipments of all sizes of AFX and the smaller diameter sizes of AFX2 and initiated a voluntary recall  of (1) the small 
remaining quantity of original AFX with Strata graft material, and (2) the larger diameter sizes of AFX2. In January 2017, we 
removed the temporary hold and resumed shipments of the remaining larger diameter sizes of AFX2.

Ovation System

In May 2011, we initiated a three-year European Post Market Registry to enroll 500 patients across 30 European centers.  

Enrollment ended in December 2013. In January 2017, we announced positive three-year results from the Ovation EU Post 
Market Registry.  The data were presented at the 2017 LINC meeting and showed that the Ovation platform has the broadest 
range of patient applicability on IFU of all commercially available infrarenal endovascular AAA devices.  The resulting 
outcomes included: 

99% freedom from aneurysm-related mortality;
99% freedom from migration, rupture, and conversion;
97% freedom from Type I/III endoleak; and

• 
• 
• 
•  Excellent freedom from secondary intervention for occlusion (97%), Type I endoleak (97%) and Type II endoleak 

95%.

In October 2014, we initiated the LIFE Study to illustrate the potential advantages of a fast track protocol including 
PEVAR, no general anesthesia, no time in ICU and a one night stay in the hospital with the Ovation System. In May 2016, we 
announced the completion of enrollment of 250 patients at 34 sites participating in the LIFE Study. In September 2016, we 
announced the results of the one-month clinical data from the LIFE Study that demonstrate that the Ovation System met the 
study primary endpoint for major adverse events at 30 days. The following are highlights of the presentation, with outcomes 
covering one-month follow-up:

•  Low major adverse event rate of 0.4%;

•  No ruptures, conversion, or secondary interventions;

• 

• 

• 

99% and 100% freedom from type I and type III endoleaks, respectively;

Fast-Track completed in 216 (87%) patients, with positive results compared to non-Fast-Track patients;

Procedure time of 84 minutes vs. 110 minutes;

•  General anesthesia use 0% vs. 18%;

• 

ICU stay 0% vs. 32%; and

•  Mean hospital stay 1.2 vs. 1.9 days.

In August 2015, we enrolled the first subject in the LUCY Study, a multi-center post-market registry designed to explore 
the clinical benefits associated with EVAR using the Ovation Abdominal Stent Graft Platform in female patients with AAA, as 
compared to males. It is the first prospective study evaluating EVAR in females, a population that has historically been 
underrepresented in EVAR clinical trials. We announced completion of enrollment of 225 patients in the LUCY study in 
February 2017. The 30-day LUCY data showed that, in women, the ultra-low profile (14F) Ovation System device resulted in: 

•  At least 28% greater EVAR eligibility for women with AAA; 
• 

1.3% major adverse events, the lowest rate reported for EVAR, compared to other contemporary, prospective, post-
market registries; 

•  No deaths; 
•  No proximal endoleaks; 
•  No limb occlusion; 
•  Low readmission rate of 3.9%; and 

8

• 

100% procedural success

In February 2015, the FDA approved the next generation Ovation iX Iliac Stent Graft for the Ovation System, and in July 
2015, the FDA approved the Ovation iX Abdominal Stent Graft System. In September 2015, the first patients were treated with 
the Ovation iX Abdominal Stent Graft System in Europe, and in August 2015, we initiated the launch of the Ovation iX System 
in the United States.

In November 2016, we announced at VEITH that the five-year results from the Ovation Global Pivotal Trial were positive 

and showed the following outcomes:

•  Broad patient applicability, with 40% of the patients treated outside the labeled indications of other EVAR devices;
• 

Stable aortic neck diameters with an average expansion of 0.1%, compared to 25% as reported with other EVAR 
devices;
97% freedom from secondary interventions related to type I endoleak; and

• 
•  No migration or conversions.

In August 2016, we announced that the first two patients were treated with the Ovation Alto® Abdominal Stent Graft 

System, which is the newest device in the Ovation System platform of abdominal stent graft systems. Ovation Alto is an 
investigational device, currently not approved in any market. It expands EVAR to include the treatment of patients with 
complex AAAs, specifically patients with very short or otherwise complex aortic neck anatomy. This is achieved by the 
conformable O-rings with CustomSeal® polymer that have been repositioned near the top of the endograft, providing seal just 
below the renal arteries. In November 2016, we received IDE approval from the FDA to conduct a clinical study with the 
Ovation Alto® Abdominal Stent Graft System in the United States.

In March 2017, we announced the enrollment of the first patients in the Expanding Patient Applicability with Polymer 

Sealing Ovation Alto Stent Graft (“ELEVATE”) IDE clinical study, our pivotal clinical trial to evaluate the safety and 
effectiveness of Ovation Alto for the repair of infrarenal AAAs. The ELEVATE IDE clinical trial is approved to enroll 75 
patients at up to 16 centers in the United States. 

The Company plans to file regulatory submissions in the third quarter of 2018 and estimates potential approval of the Alto 

device in both the U.S. and European markets in 2019.

PEVAR

Vascular access for EVAR previously required femoral artery exposure (commonly referred to as surgical cut-down) of 

one or both femoral arteries, allowing for safe introduction of the EVAR product. Complications from femoral artery exposure 
during EVAR procedures is an inherent risk of current surgical practice. PEVAR procedures do not require an open surgical cut-
down of either femoral artery, as access to the femoral artery is achieved via a needle-puncture through the skin and closure 
with use of a suture-mediated device.  Advantages to the patient and to the health care system of an entirely percutaneous 
procedure include reduced surgical procedure times, less post-operative pain, and fewer access-related wound complications.  

In April 2013, we announced FDA approval of the PEVAR indication for use with our AFX and IntuiTrak products.  Trial 
results show the safety and effectiveness of our device and PEVAR procedure facilitated with a suture-mediated closure device, 
and showed reduced surgical procedure time compared to surgical EVAR.  Other trends favoring PEVAR include less 
medication prescribed for post-operative groin pain, reduced blood loss, and less hospitalization time. To date, no other 
company has conducted a randomized prospective FDA trial to specifically obtain approval for a PEVAR indication.   

Manufacturing and Supply

Most of our commercial products are manufactured, assembled, and packaged at our 129,000 square foot leased facilities 

in Irvine, California and our 110,000 square foot leased facilities in Santa Rosa, California.

We rely on third parties for the supply of certain components used in our EVAR and EVAS products, such as the wire 
used to form our cobalt chromium alloy stent, PTFE and the raw material used in the manufacturing of polymer. While we 
obtain many of these components from single source suppliers, we believe there are alternative vendors for the supply of the 
vast majority of our required components. Many of our third party manufacturers go through a formal qualification and 
approval process, including periodic renewal to ensure fitness for use and compliance with applicable FDA requirements and 
International Organization for Standardization (“ISO”) 13485 requirements, and/or other required quality standards. 
Additionally, we actively manage supply risk with our key suppliers through a combination of negotiating favorable terms of 
supply agreements, maintaining strategic inventory levels, and maintaining frequent communications with our suppliers.

Marketing and Sales

We market and sell our EVAR products through a direct sales force and network of agents in the United States, Canada, 

New Zealand, South Korea, and fourteen European countries. In 20 other European countries, Japan, 12 Latin American 
countries, and seven other Asian countries we sell our EVAR products through independent distributors. In 2017, we marketed 
our EVAR products in 56 countries outside the United States. 

United States. We market and sell our EVAR products in the United States through a direct sales force. The primary 
customer and decision-maker for our EVAR products is the vascular surgeon, and to a lesser extent, the cardiovascular surgeon, 
interventional radiologist and the interventional cardiologist. Through our direct sales force, we provide clinical support and 
service to many of the approximately 1,600 hospitals and approximately 4,000 physicians in the United States that perform 
EVAR. Approximately 68% of our revenues for the year ended December 31, 2017 were generated from sales of our EVAR 
products in the United States.

International. We market and sell our products outside the United States through a direct sales force and through third 

party distributors and agents. Approximately 32% of our revenues for the year ended December 31, 2017 were generated from 
sales of our EVAR and EVAS products outside the United States.

 See Note 7 of the Notes to the Consolidated Financial Statements for a tabular summary of our revenue by geographic 

region for the fiscal years 2017, 2016 and 2015. 

Competition

The medical device industry is highly competitive. Any product we develop that achieves regulatory clearance or 
approval will have to compete for market acceptance and market share. We believe that the primary competitive factors in the 
AAA device market segment are:

• 

• 

• 

• 

• 

clinical effectiveness;

product safety, reliability, and durability;

ease of use;

sales force experience and relationships; and

price.

We experience significant competition and we expect that the intensity of competition will increase over time. For 

example, our major competitors, Medtronic, Inc., W.L. Gore Inc., and Cook Medical Products, Inc., have each obtained full 
regulatory approval for their EVAR products in the United States and/or other international markets. In addition to these major 
competitors, we also have smaller competitors, and emerging competitors with active EVAR system development programs.

Our major competitors have substantially greater capital resources than we do and also have greater resources in the areas 

of research and development, regulatory affairs, manufacturing, marketing, and sales. In addition, these competitors have 
multiple product offerings, which some physicians and hospitals may find more convenient when developing business 
relationships. We also compete with other medical device companies for clinical trial sites and for the hiring of qualified 
personnel, including sales representatives and clinical specialists.

Patents and Proprietary Information

We believe that our intellectual property and proprietary information is key to protecting our technology. We continue to 
build a portfolio of apparatus and method patents covering various aspects of our current and future technology. In the area of 
aorta treatment systems, our rights include 37 United States patents, 9 pending United States patent applications, 32 issued 
foreign patents and 9 pending foreign patent applications. Our current AFX-related aorta treatment related patents have 
expiration dates from 2018 to 2038. As a result of our acquisition of Nellix, we added additional patents to our portfolio which 
have evolved to currently include 22 issued United States patents, 26 pending United States patent applications, and 14 issued 
foreign patents, with expiration dates from 2018 to 2038. As a result of our merger with TriVascular, we added patents to our 
portfolio which have evolved to currently including 46 issued United States patents, 20 pending United States patent 
applications, and 87 issued foreign patents with expiration dates from 2018 to 2037. We intend to continue to file patent 
applications to strengthen our intellectual property position as we continue to develop our technology, while simultaneously 
avoiding paying unnecessary fees to maintain patents and applications when we believe it is not in our best interest.

10

       Our policy is to protect our proprietary position by, among other methods, filing United States and foreign patent 
applications to protect technology, inventions and improvements that are important to the development of our business. We also 
own trademarks to protect our brand. In addition to patents and trademarks, we rely on trade secrets and proprietary know-how 
protection as well.

       We seek protection of these trade secrets and proprietary know-how, in part, through confidentiality and proprietary 
information agreements. We make diligent efforts to require our employees, directors, consultants, and advisors to execute 
confidentiality agreements at the beginning of their employment, consulting, or other contractual relationships with us. These 
agreements provide that all confidential information developed or made known to the individual or entity during the course of 
the relationship is to be kept confidential and not be disclosed to third parties, except in specific circumstances. In the case of 
employees and certain other parties, the agreements also provide that all inventions conceived by the individual will be our 
exclusive property.

     Third-Party Reimbursement

In the United States, hospitals are the primary purchasers of our EVAR and EVAS products. Hospitals in turn bill various 
third-party payors, such as Medicare, Medicaid and private health insurance plans, for the total healthcare services required to 
treat the patient’s AAA. Government agencies, private insurers and other payors determine whether to provide coverage for a 
particular procedure and to reimburse hospitals for medical treatment. While hospitals are often reimbursed at a fixed rate 
based on the diagnosis-related group (“DRG”) established by the United States Centers for Medicare and Medicaid Service 
(“CMS”), other insurers may negotiate differing approaches with hospitals. The fixed rate of reimbursement is based on the 
procedure performed, and is unrelated to the specific medical devices used in that procedure.

Reimbursement of procedures utilizing our EVAR and EVAS products currently are covered. Some payors may deny 
reimbursement if they determine that the device used in a treatment was unnecessary, not cost-effective, or used for a non-
approved indication.

Beginning on October 1, 2015, CMS started requiring those who make claims for reimbursement to use ICD-10 codes to 

designate diagnosis and treatment of Medicare beneficiaries. The following are the ICD-10-PCS codes associated with the 
endovascular treatment of abdominal aneurysms utilizing our devices indicated for that treatment.

Outside of the United States, market acceptance of medical devices, including EVAR and EVAS systems, depends partly 

upon the availability of reimbursement within the prevailing healthcare payment system. Reimbursement levels vary 
significantly by country, and by region within some countries. Reimbursement is obtained from a variety of sources, including 
government sponsored healthcare and private health insurance plans.

Presently, the European Union (“EU”) is updating regulations for the sale and reimbursement of medical devices in EU 

countries. The current directives on active implantable medical devices (90/385/EEC) and on medical devices (93/42/EEC) will 

11

be replaced by a regulation on medical devices. The legislation will harmonize such regulations throughout all EU countries. It 
is expected that the new regulations will require: (i) stricter guidelines for clinical evidence supporting device efficacy, (ii) 
more powers for regulatory assessment bodies, (iii) stronger supervision of manufacturers, importers and distributors, and (iv) 
an extended database for medical devices and better traceability throughout the supply chain. The European Commission 
proposals have been discussed in the European Parliament and in the European Council, and a final text was agreed upon on 
June 15, 2016. Work is currently ongoing to translate the final texts in all the EU official languages and to correct technical 
inconsistencies. Final formal adoption was expected both on the Council and the Parliament sides during the first semester 
2017. Regulation would then gradually come into effect by 2020. 

     Government Regulation - Medical Devices

        Our medical devices are subject to regulation by various government agencies, including the FDA and similar agencies 
within governments outside the United States. Each of these agencies requires us to comply with laws and regulations 
governing the development, qualification, manufacturing, labeling, marketing, and distribution of our medical devices.

        United States

         In the United States, medical devices are regulated by the FDA under the Federal Food, Drug and Cosmetic Act. The FDA 
classifies medical devices into one of three classes based upon controls the FDA considers necessary to reasonably ensure their 
safety and effectiveness. Class I devices are subject to general controls such as labeling, adherence to good manufacturing practices 
and maintenance of product complaint records, but are usually exempt from premarket notification requirements. Class II devices 
are subject to the same general controls and also are subject to special controls such as performance standards, FDA guidelines, 
and may also require clinical testing prior to approval. Class III devices are subject to the highest level of controls because they 
are life-sustaining or life-supporting devices. Class III devices require rigorous clinical testing prior to their approval and generally 
require a PMA or PMA supplement approval prior to marketing for sale.

Authorization to commercially distribute a medical device in the United States is generally received in one of two ways. 
The first, known as premarket notification (i.e., the 510(k) process), requires us to submit data to the United States FDA to 
demonstrate that our medical device is substantially equivalent to another medical device that is legally marketed in the United 
States The United States FDA must issue a finding of substantial equivalence before we can commercially distribute our medical 
device. Devices that receive a finding of substantial equivalence are referred to as 510(k)-cleared devices. Modifications to 
medical devices cleared under the 510(k) process can be made under the 510(k) process, or without the 510(k) process if the 
changes do not significantly affect safety or effectiveness. 

The second process, known as premarket approval (i.e., the PMA process), requires us to collect and submit nonclinical and 
human clinical data on the medical device for its intended use to demonstrate that it is safe and effective. Human clinical data 
must be collected in compliance with FDA IDE regulations. The IDE application must be supported by data, typically including 
the results of animal and engineering testing of the device. If the IDE application is approved by the FDA, human clinical studies 
may begin at a specific number of investigational sites with a maximum number of patients. The clinical studies must be conducted 
under the review of an independent institutional review board to ensure the protection of the patients’ rights. In the PMA process, 
the FDA will approve the medical device and thereby authorize its commercial distribution in the United States if it determines 
that  the  probable  benefits  outweigh  the  risks  for  the  intended  patient  population,  and,  therefore,  makes  a  determination  of 
reasonable assurances of safety and effectiveness. The PMA process takes longer and is more expensive than the 510(k) process. 
Our Powerlink, IntuiTrak AFX, AFX2 and Ovation EVAR Systems were approved through this PMA process. The Nellix EVAS 
System is currently engaged in the PMA process and we anticipate will be made commercially available in the United States 
following PMA approval.

We are required to register as a medical device manufacturer with the FDA. Additionally, the California Department of 
Health Services (“CDHS”) requires us to register as a medical device manufacturer. Because of this, the FDA and the CDHS 
routinely inspect us for compliance with Quality System regulations. These regulations require that we manufacture our products 
and maintain related documentation in a prescribed manner with respect to manufacturing, testing and control activities. We have 
undergone and expect to continue to undergo regular Quality System inspections in connection with the manufacture of our products 
at our facility. Further, the FDA requires us to comply with various regulations regarding labeling. The Medical Device Reporting 
(“MDR”) laws and regulations require us to provide information to the FDA on deaths or serious injuries alleged to have been 
associated with the use of our devices, as well as product malfunctions that likely would cause or contribute to death or serious 
injury if the malfunction were to recur. Although physicians are permitted to use their medical judgment to apply medical devices 
to indications other than those cleared or approved by the FDA, we are prohibited from promoting products for such “off-label” 
uses, and can only market our products for the 510(k)-cleared or PMA-approved indications for use.

12

International

Internationally, our medical devices are subject to regulatory requirements in the countries in which they are sold. The 

requirements and regulatory approval processes vary from country to country. 

In the EU, one regulatory approval process exists. We must comply with the requirements of the Medical Devices Directive 
(“MDD”), and appropriately affix the CE Mark on our products to attest to such compliance. To obtain a CE Mark, our products 
must meet minimum standards of safety, performance, and quality (i.e., “Essential Requirements”), and then comply with defined 
conformity  assessment  routes. A  notified  body,  selected  by  us,  assesses  our  Quality  Management  System  and  our  product 
conformity to the Essential Requirements and the requirements of the MDD. The notified body must perform regular inspections 
to verify compliance. The EU government ministries of health ("Competent Authorities") oversee human clinical studies and 
post-market surveillance of approved products, referred to as Vigilance Reporting. We are required to report device failures and 
serious  adverse  events  potentially  related  to  product  use  to  responsible  Competent Authorities.  We  also  must  comply  with 
additional requirements of individual countries in which our products are marketed. Our Powerlink, AFX, and Ovation EVAR 
Systems and Nellix EVAS System were approved through the CE marking process.

To be sold in Japan, most medical devices must undergo thorough safety examinations and demonstrate medical efficacy 
before they are granted approval, or “Shonin”. In Japan, the MHLW, with administration by the Pharmaceutical and Medical 
Devices  Agency,  regulates  medical  devices  under  the  Pharmaceuticals  and  Medical  Device  Law  (“PMD”).  Our  quality 
management system and product conformity to the PMD are overseen by MHLW and Pharmaceutical and Medical Devices 
Agency. Our Powerlink System and AFX System were approved through the Shonin process. The Ovation System and the Nellix 
EVAS System require future approval through the foregoing process in order to be commercially available in Japan.

         To be sold in China, all medical devices are required to have licenses from the China Food and Drug Administration (“CFDA”)  
(formerly State Food & Drug Administration or SFDA). Quality system, premarket testing and clinical investigation are required 
for Class II and III devices. CFDA released a new regulation on Innovative Medical Device Registration Applications in March 
2014, which Endologix may utilize to register its product in China.  Class II and III submissions will have a full application review 
conducted; this will include a technical and administrative review. Novel and high-risk products may also be subject to an Expert 
Panel Meeting (which may result in an additional 4 to 6 months to the review process), and CFDA may conduct an onsite QMS 
audit of manufacturing facilities. The AFX System and the Ovation System, as well as the Nellix EVAS System, require future 
approval through the foregoing process in order to be commercially available in China.

We are also subject to other local, state, federal and international regulations relating to a variety of areas including laboratory 
practices, manufacturing practices, medical device export, quality system practices, as well as health care reimbursement and 
delivery of products and services.

     United States and Foreign Government Regulations - Healthcare Fraud and Abuse and Privacy Laws

Healthcare Fraud and Abuse
We are subject to various United States and foreign governmental laws and regulations relating to the manufacturing, 
labeling, marketing and selling of our products, non-compliance with which could adversely affect our business, financial 
condition and results of operations.  We have implemented and maintain a comprehensive compliance program that includes 
ongoing risk assessment, development of relevant policies, monitoring, and training of our employees to ensure compliance 
with United States and foreign laws and regulations. 

        Various United States federal and state laws and regulations pertaining to health care fraud and abuse govern how we can 
and cannot do business in the United States and globally, including the federal False Claims Act, which prohibits the 
submission of false or otherwise improper claims for payment to a federally-funded health care program, the federal Anti-
Kickback Statute, which prohibits offers to pay or receive remuneration of any kind for the purpose of inducing or rewarding 
referrals of items or services reimbursable by a Federal health care program, and similar state false claims and anti-kickback 
laws and regulations that apply to state funded health care programs. Violations of these laws and regulations are punishable by 
criminal and/or civil sanctions, including, in some instances, fines, imprisonment and, within the United States, exclusion from 
participation in federal and/or state health care programs, including Medicare and Medicaid. The interpretation and 
enforcement of these laws and regulations are uncertain and subject to rapid change. 

        We conduct a significant amount of sales activity outside of the United States. We intend to continue to pursue growth 
opportunities internationally, including in emerging markets.  Our international operations are, and will continue to be, subject 
to a complex set of laws and regulations, including:

13

• 
• 

• 
• 

• 

• 

Foreign medical reimbursement policies and programs;
Complex data privacy requirements and laws;

Ever-changing and contradictory country-specific guidelines, transparency requirements and laws;
The Foreign Corrupt Practices Act, a United States law, which prosecutes United States companies who 
engage in bribery when doing business with physicians, distributors, agents, and other third parties outside 
the United States Many physicians outside the United States are considered government officials, and United 
States companies, together with individuals who engaged in the bribery, face civil and criminal sanctions 
both in the United States and any country where bribery of a government official violates the law of that 
country;
Foreign anti-corruption laws, such as the UK Bribery Act; and

Trade protection measures, including import or export restrictions or sanctions, that may restrict us from 
doing business in and/or shipping products to certain parts of the world.

The foregoing are subject to change and evolving interpretations and any violation thereof could subject us to financial or other 
penalties.  

US and Foreign Privacy Laws

We are subject to various United States federal and state privacy and security laws and regulations that protect the 
security and privacy of individually identifiable health information. We are mindful that our systems require significant 
resources and oversight to protect employee, patient, physician and customer information.  If we fail to maintain or protect our 
information systems and data integrity effectively, we could lose existing customers, have difficulty preventing, detecting, and 
controlling fraud, have disputes with customers, physicians, and other health care professionals, have regulatory sanctions or 
other penalties imposed, have increases in operating expenses, incur expenses or lose revenues as a result of a data privacy 
breach, or suffer other adverse consequences.

We are also impacted by the privacy and security requirements of countries outside the United States Privacy standards in 

Europe and Asia have become stricter. Enforcement actions and financial penalties related to privacy in the EU are growing, 
and foreign governmental authorities have passed new laws and restrictions relating to privacy requirements and standards. The 
management of cross border transfers of information among and outside of EU member countries is becoming more complex, 
which may affect our consulting arrangements with physicians or our clinical research activities, as well as product offerings 
that involve transmission or use of clinical data.

The EU published the EU General Data Protection Regulation (“GDPR”) in April 2016. This major piece of legislation 
represents the most significant change in EU data protection law since 1995. It will apply in all EU Member States as of May 
2018. The GDPR mandates a baseline set of standards that will have a significant impact on us as we are involved in the 
processing of personal data outside the EU. It will increase the penalties for noncompliance, with fines of up to €20 million or 
4% of annual worldwide revenue.  

Any significant breakdown, intrusion, interruption, corruption, or destruction of our systems or information could have a 

material adverse effect on our business, results of operations and financial condition. Thus, we will continue our efforts to 
comply with all applicable privacy and security laws and regulations. To the best of our knowledge at this time, we do not 
expect that the ongoing cost and impact of assuring compliance with applicable privacy and security laws and regulations will 
have a material impact on our business, results of operations or financial condition.

Product Liability

The manufacture and marketing of medical devices carries the significant risk of financial exposure to product liability 

claims. Our products are used in situations in which there is a high risk of serious injury or death. Such risks will exist even 
with respect to those products that have received, or in the future may receive, regulatory approval for commercial sale. We are 
currently covered under a product liability insurance policy with coverage limits of $20 million per occurrence and $20 million 
per year in the aggregate, subject to customary deductible of $150,000. 

Employees

As of December 31, 2017, we had 675 employees (as compared to 782 employees as of December 31, 2016), including 

218 in manufacturing, 45 in research and development, 41 in regulatory and clinical affairs, 75 in quality, 191 in sales and 
marketing, and 105 in administration. We believe that the success of our business will depend on our ability to attract and retain 

14

qualified personnel. Our employees are not subject to a collective bargaining agreement, and we believe that we have good 
relations with our employees.

General Information

We were incorporated in California in March 1992 under the name Cardiovascular Dynamics, Inc. and reincorporated in 

Delaware in June 1993. In January 1999, Cardiovascular Dynamics, Inc. (by then a publicly-traded company) merged with 
privately-held Radiance Medical Systems, Inc., and we changed our name to Radiance Medical Systems, Inc. In May 2002, we 
merged with then privately-held Endologix, Inc., and we changed our name to Endologix, Inc.

Item 1A. 

Risk Factors

Before deciding to invest in our company, or to maintain or increase your investment, you should carefully consider the 
risks described below, in addition to the other information contained in this Annual Report on Form 10-K and other reports we 
have filed with the SEC. The risks and uncertainties described below are not the only ones we face. Additional risks and 
uncertainties not presently known to us, or that we currently deem immaterial, may also affect our business operations. If any 
of these risks are realized, our business, financial condition, or results of operations could be seriously harmed and, in that 
event, the market price for our common stock could decline and you may lose all or part of your investment.

These risk factors should be considered in connection with evaluating the forward-looking statements contained in this 

Annual Report on Form 10-K. These factors could cause actual results and conditions to differ materially from those projected 
in our forward-looking statements. 

Risks Related to Our Business 

All of our revenue is generated from a limited number of products, and any decline in the sales of these products will 
negatively impact our business.  

We have focused heavily on the development and commercialization of a limited number of products for the treatment of 

AAA. If we are unable to continue to achieve and maintain market acceptance of these products and do not achieve sustained 
positive cash flow from operations, we will be constrained in our ability to fund development and commercialization of 
improvements and other product lines. In addition, if we are unable to market our products as a result of a manufacturing or 
quality problem or failure to maintain regulatory approvals, we would lose our only source of revenue and our business would 
be negatively affected. 

We are in a highly competitive market segment, which is subject to rapid technological change. If our competitors are better 
able to develop and market products that are safer, more effective, less costly, easier to use, or otherwise more attractive than 
any products that we may develop, our business will be adversely impacted. 

Our industry is highly competitive and subject to rapid technological change. Our success depends, in part, upon our 
ability to maintain a competitive position in the development of technologies and products for use in the treatment of AAA and 
other aortic disorders. We face competition from both established and development stage companies. Many of the companies 
developing or marketing competing products enjoy several advantages to us, including: 

• 

• 
• 

greater financial and human resources for product development, sales and marketing and patent litigation;

greater name recognition;
long established relationships with physicians, customers, and third-party payors; 

15

• 

• 

• 

• 

additional lines of products, and the ability to offer rebates or bundle products to offer greater discounts or 
incentives; 
more established sales and marketing programs, and distribution networks; 

greater experience in conducting research and development, manufacturing, clinical trials, preparing 
regulatory submissions, and obtaining regulatory clearance or approval for products and marketing approved 
products; and

greater buying power and influence with suppliers.

Our competitors may develop and patent processes or products earlier than us, obtain regulatory clearance or approvals 

for competing products more rapidly than us, and develop more effective or less expensive products or technologies that render 
our technology or products obsolete or less competitive. We also face fierce competition in recruiting and retaining qualified 
scientific, sales, and management personnel, establishing clinical trial sites and patient enrollment in clinical trials, as well as in 
acquiring technologies and technology licenses complementary to our products or advantageous to our business. If our 
competitors are more successful than us in these matters, our business may be harmed. 

If third-party payors do not provide reimbursement for the use of our products, our revenues may be negatively impacted. 

Our success in marketing our products depends in large part on whether domestic and international government health 
administrative authorities, private health insurers and other organizations will reimburse customers for the cost of our products. 
Reimbursement systems in international markets vary significantly by country and by region within some countries, and 
reimbursement approvals must be obtained on a country-by-country basis. Further, many international markets have 
government managed healthcare systems that control reimbursement for new devices and procedures. In most markets, there 
are private insurance systems as well as government-managed systems. If sufficient reimbursement is not available for our 
current or future products, in either the United States or internationally, the demand for our products may be adversely affected 
or we may decide to cease commercial activities in any such region.

We may never realize the expected benefits of our business combination transactions. 

In addition to developing new products and growing our business internally, we have sought to grow through 
combinations with complementary businesses. Examples include our recently completed merger with TriVascular in 2016 and 
our merger with Nellix in 2010. Such business combination transactions involve risks, including the risk that we may fail to 
realize some or all of the anticipated benefits of the transaction. For example, the success of our recent business combination 
transactions largely depends on our ability to realize anticipated growth opportunities for existing products and potential new 
products. Our ability to realize these benefits, and the timing of this realization, depend upon a number of factors and future 
events, many of which we cannot control. These factors and events include, without limitation, with respect to the acquired 
products and technologies, the results of clinical trials, the receipt of applicable regulatory approvals, obtaining and maintaining 
intellectual property rights and further developing an effective sales and marketing organization in global markets. Although we 
carefully plan our business combination transactions, we may be unable to realize the expected benefits of such transactions. 

Our success depends on the growth in the number of AAA patients treated with endovascular devices. 

We estimate that over 200,000 people are diagnosed with AAA in the United States, and approximately 60,000 people 

undergo aneurysm repair, either via EVAR or open surgical repair, annually. Our growth will depend upon an increasing 
percentage of patients with AAA being diagnosed, and an increasing percentage of those diagnosed receiving EVAR, as 
opposed to an open surgical procedure. Initiatives to increase screening for AAA include SAAAVE, which was signed into law 
on February 8, 2006 in the United States. SAAAVE provides one-time AAA screening for men who have smoked some time in 
their life, and men or women who have a family history of the disease. Screening is provided as part of the “Welcome to 
Medicare” physical and such coverage began on January 1, 2007. Such general screening programs may never gain wide 
acceptance. The failure to diagnose more patients with AAA could negatively impact our revenue growth. 

Our success depends on convincing physicians to use, and continue to use, our products in more endovascular AAA 
procedures and to assist us in development of new products.

If we are unable to continue convincing physicians to use our products, our business could be negatively impacted. 
Additionally, if we fail to maintain our working relationships with health care professionals, many of our products may not be 
developed and marketed in line with the needs and expectations of the professionals who use and support our products, which 
could cause a decline in our financial performance. The research, development, marketing, and sales of many of our new and 
improved products is dependent upon our maintaining working relationships with health care professionals. We rely on these 
professionals to provide us with considerable knowledge and experience regarding the development, marketing, and sale of our 
16

products. Physicians assist us as researchers, marketing and product consultants, inventors, and public speakers. If we are 
unable to maintain our strong relationships with these professionals and continue to receive their advice and input, the 
development and marketing of our products could suffer, which could have a material adverse effect on our consolidated 
earnings, financial condition, and/or cash flows.

Manufacturing and quality problems with our products could harm our reputation and erode our competitive advantage, 
sales, and market share.
        The manufacture of many of our products is highly complex and subject to strict quality controls, due in part to rigorous 
regulatory requirements. In addition, quality is extremely important due to the serious and costly consequences of a product 
failure. Problems can arise during the manufacturing process for a number of reasons, including equipment malfunction, failure 
to follow protocols and procedures, raw material problems or human error. If these problems arise or if we otherwise fail to 
meet our internal quality standards or those of the FDA or other applicable regulatory bodies, which include detailed record-
keeping requirements, our reputation could be damaged, we could become subject to a safety alert or a recall, we could incur 
product liability and other costs, product approvals could be delayed, suspended or revoked and our business could otherwise 
be adversely affected.

Our international operations involve operating risks, which could adversely impact our net sales, results of operations, and 
financial condition. 

Sales of our products outside the United States represented approximately 32% of our revenue in 2017. As of 

December 31, 2017, we sold our products through 41 distributors located in the following countries outside of the United 
States: Argentina, Brazil, Chile, Columbia, Czech Republic, Israel, Japan, Mexico, Canada, Austria, Latvia, Romania, Poland, 
Sweden, Switzerland, Portugal, Spain, Slovakia, Italy, Hungary, Greece, Thailand, Singapore, Hong Kong, Russia, Cyprus, 
Ecuador, Australia, Turkey and South Korea. The sales territories authorized within these various distribution agreements cover 
a total of 54 countries. The sale and shipment of our products across international borders, as well as the purchase of 
components and products from international sources, subjects us to extensive United States and foreign governmental trade, 
import and export, and custom regulations and laws. 

Pursuant to the SEC rules regarding disclosure of the use of certain minerals in our products, known as "conflict minerals,” 

which are mined from the Democratic Republic of the Congo and adjoining countries, we are now required to disclose the 
procedures we employ to determine the sourcing of such minerals and metals produced from those minerals. The 
implementation of these rules could adversely affect the sourcing, supply, and pricing of materials used in our products. 
Although we intend to disclose that we utilized certain of the four conflict minerals in our products in our conflict minerals 
report for the 2017 calendar year, we have been unable in all instances to determine that our sources of these minerals have 
been certified as “conflict free.” We may continue to face difficulties in gathering this information in the future.

Compliance with these regulations is costly and exposes us to penalties for non-compliance. Other laws and regulations 
that can significantly impact us include various anti-bribery laws, including the United States Foreign Corrupt Practices Act 
and anti-boycott laws and similar laws in foreign jurisdictions. Any failure to comply with applicable legal and regulatory 
obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and 
administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of 
shipments, restrictions on certain business activities, and exclusion or debarment from government contracting. Also, the failure 
to comply with applicable legal and regulatory obligations could result in the disruption of our shipping and sales activities.

Substantially all of our sales outside of the United States are denominated in local currencies and not in United States 
dollars. Measured in local currency, a substantial portion of our international sales was generated in Europe (and primarily 
denominated in the Euro) and in Japan. The United States dollar value of our international sales varies with currency exchange 
rate fluctuations. Decreases in the value of the United States dollar to the Euro or the British Pound Sterling have the effect of 
increasing our reported revenues even when the volume of international sales has remained constant. Increases in the value of 
the United States dollar relative to the Euro or the British Pound Sterling, as well as other currencies, have the opposite effect 
and, if significant, could have a material adverse effect on our reported revenues and results of operations.

In addition, many of the countries in which we sell our products are, to some degree, subject to political, economic or 

social instability. Our international operations expose us and our distributors to risks inherent in operating in foreign 
jurisdictions. These risks include: 

• 

• 

difficulties in enforcing or defending intellectual property rights;

pricing pressure that we may experience internationally; 

17

• 
• 

• 
• 

• 
• 

• 

• 

• 
• 

• 
• 
• 

• 

a shortage of high-quality sales people and distributors; 
changes in third-party reimbursement policies that may require some of the patients who receive our products 
to directly absorb medical costs or that may necessitate the reduction of the selling prices of our products; 

the imposition of additional United States and foreign governmental controls or regulations; 
economic instability; 

changes in duties and tariffs, license obligations and other non-tariff barriers to trade; 
the imposition of restrictions on the activities of foreign agents, representatives and distributors; 

scrutiny of foreign tax authorities which could result in significant fines, penalties and additional taxes being 
imposed on us; 
laws and business practices favoring local companies; 

longer payment cycles; 
difficulties in maintaining consistency with our internal guidelines; 

difficulties in enforcing agreements and collecting receivables through certain foreign legal systems; 
the imposition of costly and lengthy new export licensing requirements; 
the imposition of United States or international sanctions against a country, company, person or entity with 
whom we do business that would restrict or prohibit continued business with the sanctioned country, 
company, person or entity; and 
the imposition of new trade restrictions.

If we experience any of these risks, our sales in international countries may be harmed and our results of operations 

would suffer. 

If we fail to develop and retain our direct sales force, our business could suffer. 

We have a direct sales force in the United States and in certain European countries. We also utilize a network of third-
party distributors for sales outside of the United States. As we launch new products and increase our marketing efforts with 
respect to existing products, we will need to retain and develop our direct sales personnel to build upon their experience, tenure 
with our products, and their relationships with customers. There is significant competition for sales personnel experienced in 
relevant medical device sales. If we are unable to attract, motivate, develop, and retain qualified sales personnel and thereby 
grow our sales force, we may not be able to maintain or increase our revenues. 

Our third-party distributors may not effectively distribute our products. 

We depend in part on medical device distributors and strategic relationships for the marketing and selling of our products 

outside of the United States and outside of certain countries in Europe. We depend on these distributors’ efforts to market our 
products, yet we are unable to control their efforts completely. In addition, we are unable to ensure that our distributors comply 
with all applicable laws regarding the sale of our products. If our distributors fail to effectively market and sell our products, 
and in full compliance with applicable laws, our operating results and business may suffer. 

If clinical trials of our current or future products do not produce results necessary to support regulatory clearance or 
approval in the United States or elsewhere, we will be unable to commercialize these products. 

We are currently conducting clinical trials. We will likely need to conduct additional clinical trials in the future to support 
new product approvals, for the approval for new indications for the use of our products, or support the use of existing products. 
Clinical testing is expensive, and typically takes many years, and carries uncertain outcomes. The initiation and completion of 
any of these studies may be prevented, delayed, or halted for numerous reasons, including, but not limited to, the following: 

• 

• 
• 
• 

• 

• 

the FDA, institutional review boards or other regulatory authorities do not approve a clinical study protocol, 
force us to modify a previously approved protocol, or place a clinical study on hold;
patients do not enroll in, or enroll at the expected rate, or complete a clinical study; 
patients or investigators do not comply with study protocols; 
patients do not return for post-treatment follow-up at the expected rate; 

patients experience serious or unexpected adverse side effects for a variety of reasons that may or may not be 
related to our products such as the advanced stage of co-morbidities that may exist at the time of treatment, 
causing a clinical study to be put on hold or terminated.

sites participating in an ongoing clinical study may withdraw, requiring us to engage new sites; 

18

• 
• 

• 
• 

• 

• 
• 
• 

difficulties or delays associated with establishing additional clinical sites; 
third-party clinical investigators decline to participate in our clinical studies, do not perform the clinical 
studies on the anticipated schedule, or are inconsistent with the investigator agreement, clinical study 
protocol, good clinical practices, and other FDA and Institutional Review Board requirements;
Failure to complete data collection analysis in a timely or accurate manner; 
regulatory inspections of our clinical studies require us to undertake corrective action or suspend or terminate 
our clinical studies; 
changes in federal, state, or foreign governmental statutes, regulations or policies; 

interim results are inconclusive or unfavorable as to immediate and long-term safety or efficacy;  
the study design is inadequate to demonstrate safety and efficacy; or 
the results of the study do not meet the study endpoints.

Clinical failure can occur at any stage of the testing. Our clinical trials may produce negative or inconclusive results, 
and we may decide, or regulators may require us, to conduct additional clinical and/or non-clinical testing in addition to those 
we have planned. Our failure to adequately demonstrate the efficacy and safety of any of our devices would prevent receipt of 
regulatory clearance or approval and, ultimately, the commercialization of that device or indication for use. 

We rely on single vendors to supply several components for our product lines, and any disruption in the supply of such 
materials could impair our ability to manufacture our products or meet customer demand for our products in a timely and 
cost effective manner. 

Our reliance on single source suppliers exposes our operations to disruptions in supply caused by: 

• 

• 

• 

• 

• 

failure of our suppliers to comply with regulatory requirements; 

any strike or work stoppage; 

disruptions in shipping; 

a natural disaster caused by fire, flood or earthquakes; or 

a supply shortage experienced by a single source supplier.

Although we take reasonable efforts to mitigate risk, a significant extending interruption from key suppliers could impact 

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

If we are unable to protect our intellectual property, our business may be negatively affected. 

Our success depends significantly on our ability to protect our intellectual property and proprietary technologies. Our 

policy is to obtain and protect our intellectual property rights. We rely on patent protection, as well as a combination of 
copyright, trade secret and trademark laws, and nondisclosure, confidentiality and other contractual restrictions, to protect our 
proprietary technology. However, these legal means afford only limited protection and may not adequately protect our rights or 
permit us to gain or keep any competitive advantage. Our pending United States and foreign patent applications may not issue 
as patents or may not issue in a form that will be advantageous to us. Any patents we have obtained, or will obtain, may be 
challenged by re-examination, inter partes review, opposition or other administrative proceeding, or in litigation. Such 
challenges could result in a determination that the patent is invalid. In addition, competitors may be able to design alternative 
methods or devices that avoid infringement of our patents. To the extent our intellectual property protection offers inadequate 
protection, or is found to be invalid, we are exposed to a greater risk of direct competition. If our intellectual property does not 
provide adequate protection against our competitors’ products, our competitive position could be adversely affected, as could 
our business. Both the patent application process and the process of managing patent disputes can be time consuming and 
expensive. Furthermore, the laws of some foreign countries may not protect our intellectual property rights to the same extent, 
as do the laws of the United States. In addition, changes in United States patent laws could prevent or limit us from filing patent 
applications or patent claims to protect our products and/or technologies or limit the exclusivity periods that are available to 
patent holders. 

We also own trade secrets and confidential information that we try to protect by entering into confidentiality agreements 
and intellectual property assignment agreements with our employees, consultants and other parties. However, such agreements 
may not be honored or, if breached, we may not have sufficient remedies to protect our confidential information. Further, our 
competitors may independently learn our trade secrets or develop similar or superior technologies. To the extent that our 
employees, consultants or others apply technological information to our projects that they develop independently or others 

19

develop, disputes may arise regarding the ownership of proprietary rights to such information, and such disputes may not be 
resolved in our favor. If we are unable to protect our intellectual property adequately, our business and commercial prospects 
will likely suffer. 

The medical device industry is subject to extensive patent litigation, and if our products or processes infringe upon the 
intellectual property of third parties, the sale of our products may be challenged and we may have to defend costly and time-
consuming infringement claims. 

We may need to engage in expensive and prolonged litigation to assert or defend any of our intellectual property rights or 

to determine the scope and validity of rights claimed by other parties. With no certainty as to the outcome, litigation could be 
too expensive for us to pursue. Our failure to prevail in such litigation or our failure to pursue litigation could result in the loss 
of our rights that could substantially hurt our business. In addition, the laws of some foreign countries do not protect our 
intellectual property rights to the same extent as the laws of the United States, if at all. 

Our failure to obtain rights to intellectual property of third parties, or the potential for intellectual property litigation, 

could force us to do one or more of the following: 

• 

• 

• 

• 

stop selling, making, or using products that use the disputed intellectual property; 

obtain a license from the intellectual property owner to continue selling, making, licensing, or using products, 
which license may not be available on reasonable terms, or at all; 

redesign our products, processes or services; or 

subject us to significant liabilities to third parties.

If any of the foregoing occurs, we may be unable to manufacture and sell our products and may suffer severe financial 
harm. Whether or not an intellectual property claim is valid, the cost of responding to it, in terms of legal fees and expenses and 
the diversion of management resources, could harm our business. 

We may face product liability claims that could result in costly litigation and significant liabilities. 

The manufacture, marketing and sale of our commercial products, and the clinical testing of our products under 

development, may expose us to significant risk of product liability claims. In the past, we have had a small number of product 
liability claims relating to our products, none of which either individually, or in the aggregate, have resulted in a material 
negative impact on our business. In the future, we may be subject to additional product liability claims, some of which may 
have a negative impact on our business. Such claims could divert our management from pursuing our business strategy and 
may be costly to defend. Regardless of the merit or eventual outcome, product liability claims may result in:

• 
• 
• 
• 
• 
• 
• 
• 

decreased demand for our products;
injury to our reputation;
injury to our relationships with our customers;
significant litigation and other costs;
substantial monetary awards to or costly settlements with patients;
product recalls;
loss of revenue; and
the inability to commercialize new products.

Although we have, and intend to maintain, product liability insurance, the coverage limits of our insurance policies may 

not be adequate to protect us from any liabilities we may incur, and one or more claims brought against us for uninsured 
liabilities or in excess of our insurance coverage may have a material adverse effect on our business and results of operations. 
In addition, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts or scope to protect 
us against losses. Any claims against us, regardless of their merit, could severely harm our reputation and financial condition, 
strain our management and other resources and adversely affect or eliminate the prospects for commercialization or sales of a 
product which is the subject of any such claim. In addition, a recall of our products, whether or not as a result of a product 
liability claim, could result in decreased demand for our products, injury to our reputation, significant litigation and other costs, 
substantial monetary awards to or costly settlements with patients, loss of revenue and our inability to commercialize new 
products or product candidates.

20

We currently are involved in litigation, and may face future claims, that could adversely affect our business and
financial condition, divert management’s attention from our business, and subject us to significant liabilities.

On January 3, 2017, a stockholder purporting to represent a class of persons who purchased our securities between August 
2, 2016 and November 16, 2016, filed a lawsuit against us and certain of our officers in the United States District Court for the 
Central District of California. The lawsuit alleges that we made materially false and misleading statements and failed to 
disclose material adverse facts about our business, operational and financial performance, in violation of federal securities laws, 
relating to FDA PMA for our Nellix EVAS System. On January 11, 2017, a second stockholder filed a similar lawsuit against us 
and certain of our officers in the United States District Court for the Central District of California. The plaintiffs sought 
unspecified monetary damages on behalf of the alleged class, interest, and attorney’s fees and costs of litigation. The first 
lawsuit, Nguyen v. Endologix, Inc. et al., Case No. 2:17-cv-0017 AB (PLAx) (C.D. Cal.), was consolidated with the second 
lawsuit, Ahmed v. Endologix, Inc. et al, Case No. 8:17-cv-00061 AB (PLAx) (C.D. Cal.), and lead Nguyen plaintiff filed a 
consolidated First Amended Complaint.  On December 5, 2017, the District Court granted Endologix’s motion to dismiss lead 
plaintiff’s First Amended Complaint, with leave to amend.  On January 9, 2018, lead plaintiff filed a Second Amended 
Complaint.  

Four shareholders have filed derivative lawsuits on behalf of Endologix, the nominal plaintiff, based on allegations 

substantially similar to those alleged by lead plaintiff in Nguyen.  Those actions consist of:  Sindlinger v. McDermott et al., 
Case No. BC662280 (Los Angeles Superior Court); Abraham v. McDermott et al., Case No. 30-2018-00968971-CU-BT-CSC 
(Orange County Superior Court); and Green v. McDermott et al., Case No. 8:17-cv-01155-AB (PLAx), which has been 
consolidated with Cocco v. McDermott et al., Case No. 8:17-cv-01183-AB (PLAx) (C.D. Cal.).

Although we believe that these lawsuits are without merit and intend to defend ourselves vigorously, we are not able to 

predict the ultimate outcome of these lawsuits. It is possible that they could cause us to incur substantial costs and that they 
could be resolved adversely to us, result in substantial damages, result in or be connected to additional claims, and divert 
management’s attention and resources, any of which could harm our business. While we maintain director and officer liability 
insurance, the amount of insurance coverage may not be sufficient to cover these claims and other claims to which we may 
become subject, and the continued availability of this insurance cannot be assured. Protracted litigation, including any adverse 
outcomes, may have an adverse impact on our business, results of operations or financial condition and could subject us to 
adverse publicity and require us to incur significant legal fees.

In July 2017, we learned that the SEC issued a Formal Order of Investigation to investigate, among other things, events 

surrounding the Nellix EVAS System and the prospect of its FDA pre-market approval. We are fully cooperating with the 
investigation but cannot predict its outcome or the timing of the investigation’s conclusions. 

Our ability to maintain our competitive position depends on our ability to attract and retain highly qualified personnel. 

Our future success depends, in part, upon our ability to retain and motivate key managerial, technical, and sales 
personnel, as well as our ability to continue to attract and retain additional highly qualified personnel. We compete for such 
personnel with other companies. We may be unsuccessful in retaining our current personnel or in hiring or retaining qualified 
personnel in the future. Key personnel may depart for various reasons, including as a result of difficulties with change or a 
desire not to remain with our company. Any unanticipated loss or interruption of services of our management team and our key 
personnel could significantly reduce our ability to meet our strategic objectives because it may not be possible for us to find 
appropriate replacement personnel should the need arise. Loss of key personnel or the inability to hire or retain qualified 
personnel in the future could have a material adverse effect on our ability to operate successfully. 

If our facilities or systems are damaged or destroyed, we may experience delays that could negatively impact our revenues or 
have other adverse effects. 

Our facilities and systems may be affected by natural or man-made disasters.  We currently conduct our manufacturing, 
development and management activities in Santa Rosa, California and Irvine, California, near known earthquake fault zones 
and seasonal wildfire activity. Our finished goods inventory is split between our Santa Rosa and Irvine locations and our 
distribution centers in Memphis, Tennessee and Tilburg, The Netherlands. We have taken precautions to safeguard our facilities 
and systems, including insurance, health and safety protocols, and off-site storage of computer data. However, our facilities and 
systems may be vulnerable to earthquakes, fire, storm, power loss, telecommunications failures, physical and software break-
ins, software viruses and similar events which could cause substantial delays in our operations, damage or destroy our 
equipment or inventory, and cause us to incur additional expenses. In addition, the insurance coverage we maintain may not be 
adequate to cover our losses in any particular case and may not continue to be available to use on acceptable terms, or at all. 

21

 
 
 
Failure to protect our information technology infrastructure against cyber-based attacks, network security breaches, service 
interruptions, or data corruption could significantly disrupt our operations and adversely affect our business and operating 
results. 

We rely on information technology and telephone networks and systems, including the Internet, to process and transmit 

sensitive electronic information and to manage or support a variety of business processes and activities, including sales, billing, 
customer service, procurement and supply chain, manufacturing, and distribution. We use enterprise information technology 
systems to record, process, and summarize financial information and results of operations for internal reporting purposes and to 
comply with regulatory financial reporting, legal, and tax requirements. Our information technology systems, some of which 
are managed by third-parties, may be susceptible to damage, disruptions or shutdowns due to computer viruses, attacks by 
computer hackers, failures during the process of upgrading or replacing software, databases or components thereof, power 
outages, hardware failures, telecommunication failures, user errors or catastrophic events. We are not aware of any breaches of 
our information technology infrastructure. Despite the precautionary measures we have taken to prevent breakdowns in our 
information technology and telephone systems, if our systems suffer severe damage, disruption or shutdown and we are unable 
to effectively resolve the issues in a timely manner, our business and operating results may suffer.

We are subject to credit risk from our accounts receivable related to our product sales, which include sales within European 
countries that are currently experiencing economic turmoil. 

The majority of our accounts receivable arise from product sales in the United States. However, we also have significant 

receivable balances from customers within the European Union, Japan, Brazil, and Argentina. Our accounts receivable in the 
United States are primarily due from public and private hospitals. Our accounts receivable outside of the United States are 
primarily due from public and private hospitals and to a lesser extent independent distributors. Our historical write-offs of 
accounts receivable have not been significant. 

We monitor the financial performance and credit worthiness of our customers so that we can properly assess and respond 
to changes in their credit profile. Our independent distributors and sub-dealers operate in certain countries such as Greece and 
Italy, where economic conditions continue to present challenges to their businesses, and thus, could place in risk the amounts 
due to us from them. These distributors are owed amounts from public hospitals that are funded by their governments. Adverse 
financial conditions in these countries may continue, thus negatively affecting the length of time that it will take us to collect 
associated accounts receivable, or impact the likelihood of ultimate collection. 

Consolidation in the health care industry could have an adverse effect on our revenues and results of operations. 

The health care industry has been consolidating, and organizations such as GPOs, independent delivery networks, and 

large single accounts continue to consolidate purchasing decisions for many of our health care provider customers. As a result, 
transactions with customers are larger, more complex, and tend to involve more long-term contracts. The purchasing power of 
these larger customers has increased, and may continue to increase, causing downward pressure on product pricing. If we are 
not one of the providers selected by one of these organizations, we may be precluded from making sales to its members or 
participants. Even if we are one of the selected providers, we may be at a disadvantage relative to other selected providers that 
are able to offer volume discounts based on purchases of a broader range of medical equipment and supplies. Further, we may 
be required to commit to pricing that has a material adverse effect on our revenues and profit margins, business, financial 
condition and results of operations. We expect that market demand, governmental regulation, third-party reimbursement 
policies and societal pressures will continue to change the worldwide health care industry, resulting in further business 
consolidations and alliances, which may exert further downward pressure on the prices of our products and could adversely 
impact our business, financial condition, and results of operations.

If any future acquisitions or business development efforts are unsuccessful, our business may be harmed. 

As part of our business strategy to be an innovative leader in the treatment of aortic disorders, we may need to acquire 
other companies, technologies, and product lines in the future. Acquisitions involve numerous risks, including the following: 

• 

• 

• 
• 

the possibility that we will pay more than the value we derive from the acquisition, which could result in 
future non-cash impairment charges; 

difficulties in integration of the operations, technologies, and products of the acquired companies, which may 
require significant attention of our management that otherwise would be available for the ongoing 
development of our business; 

the assumption of certain known and unknown liabilities of the acquired companies; and 
difficulties in retaining key relationships with employees, customers, partners, and suppliers of the acquired 
company.

22

In addition, we may invest in new technologies that may not succeed in the marketplace. If they are not successful, we 
may be unable to recover our initial investment, which could include the cost of acquiring the license, funding development 
efforts, acquiring products, or purchasing inventory. Any of these would negatively impact our future growth and cash reserves. 

Risks Related to Our Financial Condition 

We have a history of operating losses and may be required to obtain additional funds to pursue our business strategy. 

We have a history of operating losses and may need to seek additional capital in the future. We believe that our existing 
liquidity will be sufficient to meet our anticipated cash needs for at least the next 12 to 24 months. However, we may need to 
obtain additional financing to pursue our business strategy, to respond to new competitive pressures or to act on opportunities 
to acquire or invest in complementary businesses, products or technologies. Our cash requirements in the future may be 
significantly different from our current estimates and depend on many factors, including: 

• 
• 
• 
• 

• 

• 

• 

the results of our commercialization efforts for our existing and future products; 
the revenues generated by sales of our existing and future products;
the need for additional capital to fund existing and future development programs; 
the need to adapt to changing technologies and technical requirements, and the costs related thereto; 

the costs involved in obtaining and enforcing patents or any litigation by third parties regarding intellectual 
property; 

the establishment of high volume manufacturing and increased sales and marketing capabilities; and 

whether we are successful if we enter into collaborative relationships with other parties. 

In addition, we are required to make periodic interest payments to the holders of our senior convertible notes and term 

loan and to make payments of principal upon conversion or maturity. We may also be required to purchase our senior 
convertible notes from the holders thereof upon the occurrence of a fundamental change involving our company. To finance the 
foregoing, we may seek funds through borrowings or through additional rounds of financing, including private or public equity 
or debt offerings and collaborative arrangements with corporate partners. We may be unable to raise funds on favorable terms, 
or at all. 

The sale of additional equity or convertible debt securities could result in additional dilution to our stockholders. If we 
borrow additional funds or issue debt securities, these securities could have rights superior to holders of our common stock, and 
could contain covenants that will restrict our operations. We might have to obtain funds through arrangements with 
collaborative partners or others that may require us to relinquish rights to our technologies, product candidates, or products that 
we otherwise would not relinquish. If we do not obtain additional resources, our ability to capitalize on business opportunities 
will be limited, and the growth of our business will be harmed. 

Changes in the credit environment and covenant restrictions under our financing arrangements may adversely affect our 
business and financial condition. 

Future volatility in the global financial markets could increase borrowing costs or affect our ability to access the capital 

markets. Future worsening economic conditions may also adversely affect the business of our customers, including their ability 
to pay for our products. This could result in a decrease in the demand for our products, longer sales cycles, slower adoption of 
new technologies, and increased price competition.

Further, our ability to enter into or maintain existing financing arrangements on acceptable terms could be adversely 
affected if there is a material decline in the demand for our products or the prices that we can command for our products, our 
customers become insolvent or decide to reduce or discontinue their purchase of our products, we encounter significant 
regulatory, quality, manufacturing or compliance issues, or there is any other material adverse event which impacts our 
business. Any deterioration in our key financial ratios, or non-compliance with certain financial, reporting, regulatory or other 
covenants in existing or future loan or credit agreements may result in an event of default under such agreements, which could 
also adversely affect our business and financial condition.

We have limited resources to invest in research and development and to grow our business and may need to raise additional 
funds in the future for these activities. 

We believe that our growth will depend, in significant part, on our ability to develop new technologies for the treatment of 

AAA and other aortic disorders, and technology complementary to our current products. Our existing resources may not allow 

23

 
 
 
 
us to conduct all of the research and development activities that we believe would be beneficial for our future growth. As a 
result, we may need to seek funds in the future to finance these activities. If we are unable to raise funds on favorable terms, or 
at all, we may not be able to increase our research and development activities and the growth of our business may be negatively 
impacted. 

The accounting method for convertible debt securities that may be settled in cash, such as our senior convertible notes, is 
the subject of recent changes that could have a material effect on our reported financial results. 

In May 2008, the Financial Accounting Standards Board ("FASB"), issued FASB Staff Position No. APB 14-1, 
Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash 
Settlement), which has subsequently been codified as Accounting Standards Codification 470-20, Debt with Conversion and 
Other Options, which we refer to as ASC 470-20. Under ASC 470-20, an entity must separately account for the liability and 
equity components of the convertible debt instruments (such as our senior convertible notes) that may be settled entirely or 
partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. The effect of ASC 470-20 on the 
accounting for our senior convertible notes is that the equity component is required to be included in the additional paid-in 
capital section of stockholders’ equity on our consolidated balance sheets and the value of the equity component would be 
treated as original issue discount for purposes of accounting for the debt component of such notes. As a result, we will be 
required to record a greater amount of non-cash interest expense in current periods presented as a result of the accretion of the 
discounted carrying value of our senior convertible notes to their face amount over the term of such notes. We will report lower 
net income in our financial results because ASC 470-20 will require interest to include both the current period’s accretion of the 
debt discount and the instrument’s coupon interest, which could adversely affect our reported or future financial results and the 
market price of our common stock. 

In addition, under certain circumstances, convertible debt instruments (such as the notes) that may be settled entirely or 

partly in cash are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon 
conversion of the notes are not included in the calculation of diluted earnings per share except to the extent that the conversion 
value of the notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the 
transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess, if we 
elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to 
permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares 
issuable upon conversion of the notes, then our diluted earnings per share would be adversely affected. 

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay 
our debt. 

Our ability to make scheduled payments of the principal of, to pay interest on, to pay any cash due upon conversion of or 

to refinance our indebtedness, including the senior convertible notes, depends on our future performance, which is subject to 
economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow 
from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to 
generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or 
obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness 
will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these 
activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. 

The expense and potential unavailability of insurance coverage for our company may have an adverse effect on our 
financial position and results of operations. 

While we currently have insurance for our business, property, directors and officers, and product liability, such insurance 

coverage is increasingly costly and the scope of coverage is narrower, and we may be required to assume more risk in the 
future. If we are subject to claims or suffer a loss or damage in excess of our insurance coverage, we will be required to cover 
the amounts outside of or in excess of our insurance limits. If we are subject to claims or suffer a loss or damage that is outside 
of our insurance coverage, we may incur significant costs associated with loss or damage that could have an adverse effect on 
our financial position and results of operations. Furthermore, any claims made on our insurance policies may impact our ability 
to obtain or maintain insurance coverage at reasonable costs or at all. We do not have the financial resources to self-insure, and 
it is unlikely that we will have these financial resources in the foreseeable future. Our product liability insurance covers our 
products and business operations, but we may need to increase and expand this coverage commensurate with our expanding 
business. 

24

Risks Related to Regulation of Our Industry 

Healthcare policy changes, including recent federal legislation to reform the United States healthcare system, may have a 
material adverse effect on us. 

In response to perceived increases in health care costs in recent years, there have been and continue to be proposals by the 

federal government, state governments, regulators and third-party payors to control these costs and, more generally, to reform 
the United States healthcare system. Certain of these proposals could limit the prices we are able to charge for our products or 
the amounts of reimbursement available for our products and could limit the acceptance and availability of our products. 
Moreover, as discussed below, recent federal legislation would impose significant new taxes on medical device makers such as 
us. The adoption of some or all of these proposals, including the recent federal legislation, could have a material adverse effect 
on our financial position and results of operations. 

On March 23, 2010, President Obama signed the Patient Protection and Affordable Care Act, as amended by the Health 

Care and Education Affordability Reconciliation Act (the “PPACA”). The total cost imposed on the medical device industry by 
the PPACA may be up to approximately $20 billion over ten years. The PPACA includes, among other things, a deductible 
2.3% excise tax on any entity that manufactures or imports medical devices offered for sale in the United States, with limited 
exceptions, effective January 1, 2013. This excise tax will result in a significant increase in the tax burden on our industry, and 
if any efforts we undertake to offset the excise tax are unsuccessful, the increased tax burden could have an adverse effect on 
our results of operations and cash flows. Other elements of the PPACA, including comparative effectiveness research, an 
independent payment advisory board, payment system reforms including shared savings pilots and other provisions, may 
significantly affect the payment for, and the availability of, healthcare services and result in fundamental changes to federal 
healthcare reimbursement programs, any of which may materially affect numerous aspects of our business. 

On December 18, 2015, President Obama signed the Consolidated Appropriations Act of 2016, which imposed a two-year 
moratorium on the 2.3% excise tax beginning on January 1, 2016 and ending on December 31, 2017. On January 22, 2018, the 
continuing resolution extended this moratorium for an additional two years, through the 2019 calendar year. The continuing 
resolution provides that this additional delay applies to sales made after December 31, 2017. Therefore, as a result of both 
moratoriums, the medical devices tax will not apply to any sales made between January 1, 2016 and December 31, 2019. Upon 
the end of this period we believe the PPACA could continue to have an adverse effect on our results of operations and cash 
flows. 

Our future success depends on our ability to develop, receive regulatory clearance or approval for, and introduce new 
products or product enhancements that will be accepted by the market in a timely manner. 

It is important to our business that we continue to build a more complete product offering for treatment of AAA and other 

aortic disorders. As such, our success will depend in part on our ability to develop and introduce new products. However, we 
may not be able to successfully develop and obtain regulatory clearance or approval for product enhancements, or new 
products, or these products may not be accepted by physicians or the payors who financially support many of the procedures 
performed with our products. 

The success of any new product offering or enhancement to an existing product will depend on several factors, including 

our ability to: 

• 
• 
• 
• 

• 
• 
• 

• 

• 

properly identify and anticipate physicians and patient needs; 
develop and introduce new products or product enhancements in a timely manner; 
avoid infringing upon the intellectual property rights of third parties; 
demonstrate, if required, the safety and efficacy of new products with data from preclinical studies and 
clinical trials; 
obtain the necessary regulatory clearances or approvals for new products or product enhancements; 
be fully FDA-compliant with marketing of new devices or modified products; 
provide adequate training to potential users of our products; 

receive adequate coverage and reimbursement for procedures performed with our products; and 

develop an effective and FDA-compliant, dedicated marketing and distribution network.

If we do not develop new products or product enhancements in time to meet market demand or if there is insufficient 

demand for these products or enhancements, our results of operations will suffer. 

25

Our business is subject to extensive governmental regulation that could make it more expensive and time consuming for us 
to introduce new or improved products. 

Our products must comply with regulatory requirements imposed by the FDA in the United States, and similar agencies in 

foreign jurisdictions. These requirements involve lengthy and detailed laboratory and clinical testing procedures, sampling 
activities, an extensive agency review process, and other costly and time-consuming procedures. It often takes several years to 
satisfy these requirements, depending on the complexity and novelty of the product. We also are subject to numerous additional 
licensing and regulatory requirements relating to safe working conditions, manufacturing practices, environmental protection, 
fire hazard control, and disposal of hazardous or potentially hazardous substances. Some of the most important requirements 
we face include: 

• 

• 

• 
• 

• 

• 

• 

FDA Regulations (Title 21 CFR); 

European Union CE mark requirements, including the new Medical Device Regulations and MEDDEV 2.7.1 
Rev.4, which implement stricter requirements for clinical data to support new product approvals; 
Other international regulatory approval requirements;
Medical Device Single Audit Program (“MDSAP”); 

Medical Device Quality Management System Requirements (21 CFR 820, ISO 13485:2003, EN ISO 
13485:2012, ISO 13485:2016, and other similar international regulations); 
Occupational Safety and Health Administration requirements; and 

California Department of Health Services requirements.

Government regulation may impede our ability to conduct continuing clinical trials and to manufacture our existing and 
future products. Government regulation also could delay our marketing of new products for a considerable period of time and 
impose costly procedures on our activities. The FDA and other regulatory agencies may not approve any of our future products 
on a timely basis, if at all. Any delay in obtaining, or failure to obtain, such approvals could negatively impact our marketing of 
any proposed products and reduce our product revenues. 

Our products remain subject to strict regulatory controls on manufacturing, marketing and use. We may be forced to 
modify or recall our product after release in response to regulatory action or unanticipated difficulties encountered in general 
use. Any such action could have a material effect on the reputation of our products and on our business and financial position. 

Further, regulations may change, and any additional regulation could limit or restrict our ability to use any of our 
technologies, which could harm our business. We could also be subject to new international, federal, state or local regulations 
that could affect our research and development programs and harm our business in unforeseen ways. If this happens, we may 
have to incur significant costs to comply with such laws and regulations, which will harm our results of operations. 

The potential off-label promotion and subsequent off-label use of our products may harm our image in the marketplace and 
result in government investigations and/or penalties.

The products we currently market have been cleared or approved by the FDA and international regulatory authorities for 
specific indications for use, including in specific AAA anatomies. Physicians have the discretion, however, to use our products 
outside of those cleared/approved indications for use, a practice known as “off-label” use. Off-label use of our and our 
competitors’ products by physicians is common in the AAA field.  Though physicians in most countries have the discretion to 
engage in off-label use of our products, if we are deemed by the FDA or other regulatory bodies to have engaged in the 
promotion of our products for any such off-label use, we could be subject to prohibitions on the sale or marketing of our 
products in the United States or other jurisdictions, face significant fines and penalties, and be required to enter into onerous 
corporate integrity agreements, consent decrees or similar court or agency-imposed agreements.  The imposition of any such 
fines, penalties or sanctions could affect our reputation and position within the industry and could materially and adversely 
affect our business, financial condition, results of operations and prospects, which in turn could cause our stock price to 
decline. Additionally, the use of our products for indications other than those cleared/approved by the FDA or international 
regulatory authorities may result in suboptimal outcomes that could harm our reputation in the marketplace among physicians 
and patients. Physicians may misuse our products or use improper techniques if they are not adequately trained, potentially 
leading to injury and an increased risk of product liability and similar claims. If our products are misused or used with improper 
technique, we may become subject to costly litigation by our customers or their patients. Product liability claims could divert 
management’s attention from our core business, be expensive to defend, and result in sizable damage awards against us that 
may not be covered by insurance.    

26

Our products may in the future be subject to product recalls or voluntary market withdrawals that could harm our 
reputation, business and financial results. 

The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products 
in the event of material deficiencies or defects in design or manufacture that could affect patient safety. In the case of the FDA, 
the authority to require a recall must be based on an FDA finding that there is a reasonable probability that the device would 
cause serious adverse health consequences or death. Manufacturers may, under their own initiative, recall a product if any 
material deficiency in a device is found or suspected. A government-mandated recall or voluntary recall by us or one of our 
distributors could occur as a result of component failures, manufacturing errors, design or labeling defects or other issues. 
Recalls, which include corrections as well as removals, of any of our products would divert managerial and financial resources 
and could have an adverse effect on our financial condition, harm our reputation with customers, and reduce our ability to 
achieve expected revenues. 

We are required to comply with medical device reporting (“MDR”) requirements and must report certain malfunctions, 
deaths, and serious injuries associated with our products, which can result in voluntary corrective actions or agency 
enforcement actions. 

Under the FDA MDR regulations, medical device manufacturers are required to submit information to the FDA when 
they receive a report or become aware that a device has or may have caused or contributed to a death or serious injury or has or 
may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All 
manufacturers placing medical devices on the market in the European Economic Area are legally bound to report any serious or 
potentially serious incidents involving devices they produce or sell to the regulatory agency, or Competent Authority, in whose 
jurisdiction the incident occurred.

Malfunction of our products could result in future voluntary corrective actions, such as recalls, including corrections, 

or customer notifications, or agency action, such as inspection or enforcement actions. If malfunctions do occur, we may be 
unable to correct the malfunctions adequately or prevent further malfunctions, in which case we may need to cease manufacture 
and distribution of the affected products, initiate voluntary recalls, and redesign the products. Regulatory authorities may also 
take actions against us, such as ordering recalls, imposing fines, or seizing the affected products. Any corrective action, whether 
voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business, 
and may harm our reputation and financial results. 

We may be subject to federal, state and foreign healthcare fraud and abuse laws and regulations, and a finding of failure to 
comply with such laws and regulations could have a material adverse effect on our business. 

Our operations may be directly or indirectly affected by various broad federal, state or foreign healthcare fraud and abuse 

laws. In particular, the federal Anti-Kickback Statute prohibits any person from knowingly and willfully offering, paying, 
soliciting or receiving remuneration, directly or indirectly, in return for or to induce the referring, ordering, leasing, purchasing 
or arranging for or recommending the ordering, purchasing or leasing of an item or service, for which payment may be made 
under federal healthcare programs, such as the Medicare and Medicaid programs. We are also subject to the federal HIPAA 
statute, which created federal criminal laws that prohibit executing a scheme to defraud any health care benefit program or 
making false statements relating to health care matters, and federal “sunshine” laws that require transparency regarding 
financial arrangements with health care providers, such as the reporting and disclosure requirements imposed by PPACA on 
drug manufacturers regarding any “transfer of value” made or distributed to prescribers and other health care providers. 

In addition, the federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, 
or the knowing use of false statements to obtain payment from the federal government. Suits filed under the False Claims Act, 
known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly 
known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. When an 
entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages 
sustained by the government, plus civil penalties for each separate false claim. Various states have also enacted laws modeled 
after the federal False Claims Act. 

Many states have also, adopted laws similar to each of the above federal laws, such as anti-kickback and false claims laws 

which may apply to items or services reimbursed by any third-party payor, including commercial insurers as well as laws that 
restrict our marketing activities with physicians, and require us to report consulting and other payments to physicians. Some 
states mandate implementation of commercial compliance programs to ensure compliance with these laws. We also are subject 
to foreign fraud and abuse laws, which vary by country. For instance, in the European Union, legislation on inducements 
offered to physicians and other healthcare workers or hospitals differ from country to country. Breach of the laws relating to 
such inducements may expose us to the imposition of criminal sanctions.

27

The risk of our being found in violation of these laws is increased by the fact that many of them have not been fully 

interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Moreover, 
recent health care reform legislation has strengthened these laws. Further, we expect there will continue to be federal and state 
laws and/or regulations, proposed and implemented, that could impact our operations and business. The extent to which future 
legislation or regulations, if any, relating to health care fraud abuse laws and/or enforcement, may be enacted or what effect 
such legislation or regulation would have on our business remains uncertain. If our operations are found to be in violation of 
any of the laws described above or any other governmental regulations that apply to us now or in the future, we may be subject 
to penalties, including civil and criminal penalties, damages, fines, exclusion from governmental health care programs, and the 
curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our 
financial results. 

We may be subject to health information privacy and security laws and regulations, and a finding of failure to comply with 
such laws and regulations could have a material adverse effect on our business. 

The HIPAA statute, and its implementing regulations, safeguard the privacy and security of individually-identifiable 
health information. Certain of our operations may be subject to these requirements. Penalties for noncompliance with these 
rules include both criminal and civil penalties. In addition, the Health Information Technology for Economic and Clinical 
Health Act (“HITECH Act”) expanded federal health information privacy and security protections. Among other things, 
HITECH makes certain of HIPAA’s privacy and security standards directly applicable to “business associates”-independent 
contractors or agents of covered entities that receive or obtain protected health information in connection with providing a 
service on behalf of a covered entity. HITECH also set forth new notification requirements for health data security breaches, 
increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other 
persons, and gave state attorneys general new authority to enforce HIPAA and seek attorney’s fees and costs associated with 
pursuing federal civil actions. 

Risks Related to Our Common Stock

We will be obligated to issue additional shares of our common stock to the former stockholders of Nellix as a result of our 
satisfaction of a certain milestone set forth in the merger agreement with Nellix and the other parties thereto, resulting in 
stock ownership dilution. 

Under the terms of the merger agreement with Nellix and the other parties thereto, we agreed to issue additional shares of 
our common stock to the former stockholders of Nellix as contingent consideration upon our satisfaction of one or both of two 
milestones related to the Nellix System and described in the merger agreement, or upon a change of control of our company 
prior to our completion of one or both milestones. On June 17, 2014, we issued an additional 2.7 million shares of our common 
stock to the former stockholders of Nellix upon achievement of a revenue-based milestone. One additional regulatory related 
milestone remains, and the maximum aggregate number of shares of our common stock remaining issuable to the former Nellix 
stockholders upon our achievement of such regulatory milestone, or upon a change of control of our company prior to our 
achievement of such milestone, assuming the average per share closing price of our common stock (as determined under the 
terms of the Nellix merger agreement) at such time is 2.9 million shares. 

Issuing additional shares of our common stock to the former stockholders in satisfaction of contingent consideration 

dilutes the ownership interests of holders of our common stock on the dates of such issuances. If we are unable to realize the 
strategic, operational and financial benefits anticipated from our acquisition of Nellix, our stockholders may experience dilution 
of their ownership interests in our company upon any such future issuances of shares of our common stock without receiving 
any commensurate benefit. 

Our operating results may vary significantly from quarter to quarter, which may negatively impact our stock price in the 
future. 

Our quarterly revenues and results of operations may fluctuate due to, among others, the following reasons: 

• 
• 
• 
• 
• 

• 
• 

physician acceptance of our products; 
the conduct and results of clinical trials; 
the timing and expense of obtaining future regulatory approvals; 
fluctuations in our expenses associated with expanding our operations; 
the introduction of new products by our competitors;

the timing of product launch may lead to excess or obsolete inventory; 
supplier, manufacturing or quality problems with our devices; 

28

• 
• 

• 
• 

litigation expenses;
the timing of stocking orders from our distributors; 

changes in our pricing policies or in the pricing policies of our competitors or suppliers; and 
changes in third-party payors’ reimbursement policies.

Because of these and possibly other factors, it is likely that in some future period our operating results will not meet 

investor expectations or those of public market analysts. 

Any unanticipated change in revenues or operating results is likely to cause our stock price to fluctuate since such 

changes reflect new information available to investors and analysts. New information may cause investors and analysts to 
revalue our business, which could cause a decline in the trading price of our stock. 

The price of our stock may fluctuate unpredictably in response to factors unrelated to our operating performance. 

The stock market periodically experiences significant price and volume fluctuations that are unrelated to the operating 
performance of particular companies. These broad market fluctuations may cause the market price of our common stock to 
drop. In particular, the market price of securities of medical device companies, like ours, has been very unpredictable and may 
vary in response to: 

• 

• 

• 
• 

• 

• 

• 

• 

• 
• 

announcements by us or our competitors concerning technological innovations; 

introductions of new products; 

FDA and foreign regulatory actions; 
developments or disputes relating to patents or proprietary rights; 

maintain the effectiveness of our Quality System;

failure of our results of operations to meet the expectations of stock market analysts and investors; 

changes in stock market analyst recommendations regarding our common stock; 

the conversion of some or all of our senior convertible notes and any sales in the public market of shares of 
our common stock issued upon conversion of such notes;

changes in healthcare policy in the United States or other countries; and 
general stock market and economic conditions and other factors unrelated to our operating performance.

These factors may materially and adversely affect the market price of our common stock.

We may not achieve our financial guidance or projected goals and objectives in the time periods that we anticipate or 
announce publicly, which could have an adverse effect on our business and could cause the market price of our ordinary 
shares to decline.

We typically provide financial guidance that is based on management’s then current expectations and typically does not 

contain any significant margin of error or cushion for any specific uncertainties or for the uncertainties inherent in all financial 
forecasting. The failure to achieve our financial guidance or the projections of analysts and investors could have an adverse 
effect on our business, disappoint analysts and investors, and cause the market price of our common stock to drop. We also set 
goals and objectives for, and make public statements regarding, the timing of certain accomplishments and milestones 
regarding our business or operating results, such as the timing of financial objectives, new products, clinical trials, and 
regulatory actions. The actual timing of these events can vary dramatically due to a number of factors, including the risk factors 
described in this report. As a result, we may be unable to achieve our projected goals and objectives in the time periods that we 
anticipate or announce publicly. The failure to achieve such projected goals and objectives in the time periods that we anticipate 
or announce publicly could have an adverse effect on our business, disappoint investors and analysts, and cause the market 
price of our common stock to decline.

Trading in our stock over the last twelve months has been limited, so investors may not be able to sell as much stock as they 
wish at prevailing prices. 

The average daily trading volume in our common stock for the twelve months ended December 31, 2017 was 

approximately 1,142,122 shares. If limited trading in our stock continues, it may be difficult for investors to sell their shares in 
the public market at any given time at prevailing prices. Moreover, the market price for shares of our common stock may be 
made more volatile because of the relatively low volume of trading in our common stock. When trading volume is low, 

29

significant price movement can be caused by the trading of a relatively small number of shares. Volatility in our common stock 
could cause stockholders to incur substantial losses. 

Some provisions of our charter documents and Delaware law may make takeover attempts difficult, which could depress the 
price of our stock and inhibit one’s ability to receive a premium price for their shares. 

Provisions of our amended and restated certificate of incorporation could make it more difficult for a third party to 
acquire control of our business, even if such change in control would be beneficial to our stockholders. Our amended and 
restated certificate of incorporation allows our board of directors to issue up to five million shares of preferred stock and to fix 
the rights and preferences of such shares without stockholder approval. Any such issuance could make it more difficult for a 
third party to acquire our business and may adversely affect the rights of our stockholders. In addition, our board of directors is 
divided into three classes for staggered terms of three years. We are also subject to anti-takeover provisions under Delaware 
law, each of which could delay or prevent a change of control. Together these provisions may delay, deter or prevent a change 
in control of us, adversely affecting the market price of our common stock. 

We do not anticipate declaring any cash dividends on our common stock. 

We have never declared or paid cash dividends on our common stock and do not plan to pay any cash dividends in the 
near future. Our current policy is to retain all funds and any earnings for use in the operation and expansion of our business. 
Our revolving credit facility and term loan contain restrictions prohibiting us from paying any cash dividends without the 
lender’s prior approval. If we do not pay dividends, a return on one’s investment may only occur if our stock price rises above 
the price it was purchased.

Properties

On June 12, 2013, we entered into a lease agreement for two adjacent office, research and development, and 

manufacturing facilities in Irvine, California. The premises consist of approximately 129,000 combined square feet. The lease 
has a 15-year term beginning January 1, 2014 and provides for one optional 5 year extension. The initial base rent under the 
lease is $1.9 million per year, payable in monthly installments, and escalates by 3% per year for years 2015 through 2019, and 
4% per year for years 2020 and beyond. We received a rent abatement for the first nine months of the lease. Refer to Note 8 of 
the Notes to the Consolidated Financial Statements for further discussion of properties.

Our facility in Rosmalen, The Netherlands is an administrative office of approximately 2,900 square feet under an 

operating lease scheduled to expire in December 2020.

In conjunction with the TriVascular merger, we assumed the lease for TriVascular's facility in Santa Rosa, California. We 

use the Santa Rosa facility for manufacturing, research & development, and administrative purposes, and the facility consists 
of 110,000 square feet under an operating lease scheduled to expire in February 2023, which may be renewed for an additional 
five years.

We believe that all of our facilities and equipment are in good condition, suitable and adequate for their purposes, and are 

maintained on a consistent basis for sound operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

 The following discussion and analysis should be read in conjunction with “Selected Financial Data” and our audited 
Consolidated Financial Statements and the related notes thereto included in this Annual Report on Form 10-K. This discussion 
contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those 
anticipated in the forward-looking statements as a result of various factors including the risks we discuss in Item 1A of Part I, 
“Risk Factors” and elsewhere in this Annual Report on Form 10-K.

Overview 

Our Business

Our corporate headquarters are located in Irvine, California and manufacturing facilities are located in Irvine and Santa 
Rosa, California. We develop, manufacture, market, and sell innovative medical devices for the treatment of aortic disorders. 
Our principal products are intended for the treatment of abdominal aortic aneurysms (“AAA”). Our AAA products are built on 
two platforms: (1) traditional minimally-invasive endovascular repair (“EVAR”), and (2) endovascular sealing (“EVAS”), our 
innovate solution for sealing the aneurysm sac while maintaining blood flow through two blood flow lumens. 

We sell our products through (i) our direct United States and European sales forces and (ii) third-party international 

distributors and agents in Europe and in other parts of the world.

For an overview of our business, products, product development initiatives, and clinical trials, please see Item 1, 

“Business.”

Characteristics of Our Revenue and Expenses

Revenue

Revenue is derived from sales of our EVAR and EVAS products (including extensions and accessories) to hospitals upon 

completion of each AAA repair procedure, or from sales to distributors upon title transfer (which is typically at shipment), 
provided our other revenue recognition criteria have been met.

Cost of Goods Sold

Cost of goods sold includes compensation (including stock-based compensation) and benefits of production personnel and 
production support personnel. Cost of goods sold also includes depreciation expense for production equipment, amortization of 
developed technology, production materials and supplies expense, allocated facilities-related expenses, and certain direct costs 
such as shipping.

Research and Development

Research and development expenses consist of compensation (including stock-based compensation) and benefits for 

research and development personnel, materials and supplies, research and development consultants, outsourced and licensed 
research and development costs, and allocated facilities-related costs.  Our research and development activities primarily relate 
to the development and testing of new devices and methods to treat aortic disorders.

Clinical and Regulatory

Clinical and regulatory expenses consist of compensation (including stock-based compensation) and benefits for clinical 

and regulatory personnel, regulatory and clinical payments related to studies, regulatory costs related to registration and 
approval activities, and allocated facilities-related costs.  Our clinical and regulatory activities primarily relate to obtaining 
regulatory approval for the commercialization of our devices. 

Marketing and Sales

Marketing and sales expenses primarily consist of compensation (including stock-based compensation) and benefits for 
our sales force, clinical specialist, internal sales support functions, and marketing personnel.  It also includes costs attributable 
to marketing our products to our customers and prospective customers.

General and Administrative

General and administrative expenses primarily include compensation (including stock-based compensation) and benefits 
for personnel that support our general operations such as information technology, executive management, financial accounting, 

33

and human resources.  General and administrative expenses also include bad debt expense, patent and legal fees, financial audit 
fees, insurance, recruiting fees, other professional services, the federal Medical Device Excise Tax, and allocated facilities-
related expenses.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with United States generally accepted accounting principles 
(“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and 
the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue 
and expenses during the periods presented.  While management believes these estimates are reasonable and consistent, they are 
by their very nature, estimates of amounts that will depend on future events. Accordingly, actual results could differ from these 
estimates. Our Audit Committee of the Board of Directors periodically reviews our significant accounting policies. Our critical 
accounting policies arise in conjunction with the following:

•  Revenue recognition and accounts receivable;

Inventory - lower of cost or market;

• 
•  Business combinations;
•  Goodwill and intangible assets - impairment analysis;
• 

Stock-based compensation;

•  Contingent consideration for business acquisition; and

•  Litigation accruals.

Revenue Recognition and Accounts Receivable

We recognize revenue when all of the following criteria are met:

•  We have appropriate evidence of a binding arrangement with our customer;

•  The sales price for our product (including extensions and accessories) is established with our customer;

•  Our product has been used by the hospital in an AAA repair procedure, or our distributor 

has assumed title with no right of return, as applicable; and

•  Collection from our customer is reasonably assured at the time of sale.

For sales made to a direct customer (i.e., hospitals), we recognize revenue upon completion of an AAA repair procedure, 
when our product is implanted in a patient. For sales to distributors, we recognize revenue at the time of title transfer, which is 
typically at shipment. We do not offer any right of return to our customers, other than honoring our standard warranty.

         We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to pay 
amounts due. These estimates are based on our review of the aging of customer balances, correspondence with the customer, 
and the customer’s payment history.

Inventory - Lower of Cost or Market

We adjust our inventory value for estimated amounts of obsolete or unmarketable items. Such assumptions involve 

projections of future customer demand, as driven by economic and market conditions, and the product’s shelf life. If actual 
demand, or economic or market conditions are less favorable than those projected by us, additional inventory write-downs may 
be required.

Business Combinations

The application of acquisition accounting to a business acquisition requires that we identify the individual assets acquired 

and liabilities assumed and estimate the fair value of each. The fair value of assets acquired and liabilities assumed in a 
business acquisition are recognized at the acquisition date, with the purchase price exceeding the fair values being recognized 
as goodwill. Determining fair value of identifiable assets, particularly intangibles, liabilities acquired and contingent 
obligations assumed requires management to make estimates. In certain circumstances, the allocations of the purchase price are 
based upon preliminary estimates and assumptions and subject to revision when we receive final information, including 
appraisals and other analysis. Accordingly, the measurement period for such purchase price allocations will end when the 
information, or the facts and circumstances, becomes available, but will not exceed twelve months. We will recognize 
measurement-period adjustments during the period of resolution, including the effect on earnings of any amounts that would 
have been recorded in previous periods if the accounting had been completed at the acquisition date.

34

 
 
Goodwill and intangible assets often represent a significant portion of the assets acquired in a business combination. We 
recognize the fair value of an acquired intangible apart from goodwill whenever the intangible arises from contractual or other 
legal rights, or when it can be separated or divided from the acquired entity and sold, transferred, licensed, rented or exchanged, 
either individually or in combination with a related contract, asset or liability. Intangible assets consist primarily of technology, 
customer relationships, and trade name and trademarks acquired in business combinations and in-process research and 
development (“IPR&D”). We generally assess the estimated fair values of acquired intangibles using a combination of 
valuation techniques. To estimate fair value, we are required to make certain estimates and assumptions, including future 
economic and market conditions, revenue growth, market share, operating costs and margins, and risk-adjusted discount rates. 
Our estimates require significant judgment and are based on historical data, various internal estimates, and external sources. 
Our assessment of IPR&D also includes consideration of the risk that the projects may not achieve technological feasibility.

Goodwill and Intangible Assets - Impairment Analysis

Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are tested for impairment 

annually as of June 30, or whenever events or changes in circumstances indicate that the asset might be impaired.

We evaluate the possible impairment of definite-lived intangible assets if/when events or changes in circumstances occur 

that indicate that the carrying value of assets may not be recoverable. The impairment reviews require significant estimates 
about fair value, including estimates of future cash flows, selection of appropriate discount rates, and estimates of long-term 
growth rates. If actual results, or the forecasts and estimates used in future impairment analysis, are lower than the original 
estimates used to assess the recoverability of these assets, we could incur impairment charges.  

Stock-Based Compensation

We recognize stock-based compensation expense for employees based on fair value at the date of grant.  For awards 
granted to consultants, the award is marked-to-market each reporting period, with a corresponding adjustment to stock-based 
compensation expense.  The fair value of equity awards that are expected to vest is amortized on a straight-line basis over (i) 
the requisite service period or (ii) the period from grant date to the expected date of the completion of the performance 
condition for vesting of the award. Stock-based compensation expense recognized is net of an estimated forfeiture rate, which 
is updated as appropriate. 

We use the Black-Scholes option pricing model to value stock option grants. The Black-Scholes option pricing model 
requires the input of subjective assumptions, including the expected volatility of our common stock, expected risk-free interest 
rate, and the option’s expected life.  The fair value of our restricted stock is based on the closing market price of our common 
stock on the date of grant. A portion of restricted stock vesting is dependent on us achieving certain regulatory and financial 
milestones. We use judgment in estimating the likelihood and timing of achieving these milestones. Each period, we will 
reassess the likelihood and estimate the timing of reaching these milestones, and will adjust the expense accordingly.

Contingent Consideration for Business Acquisition

We determine the fair value of contingently issuable common stock related to the Nellix acquisition using a probability-

based income approach and an appropriate discount rate.  Changes in the fair value of the contingently issuable common stock 
are determined each period end and recorded in the other income (expense) section of the Consolidated Statements of 
Operations and Comprehensive Loss and the current and non-current liabilities section of the Consolidated Balance Sheets.  
The fair value of the contingent consideration liability could be impacted by changes such as: (i) fluctuations in the price of our 
common stock, or (ii) the timing of achieving the underlining milestones.

Litigation Accruals

From time to time we are involved in various claims and legal proceedings of a nature considered normal and incidental 
to our business. These matters may include product liability, intellectual property, employment, and other general claims. We 
accrue for contingent liabilities when it is probable that a liability has been incurred and the amount can be reasonably 
estimated. The accruals are adjusted periodically as assessments change or as additional information becomes available.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, which amends the FASB Accounting Standards Codification and 

creates Topic 842, “Leases.” The new topic supersedes Topic 840, “Leases,” and increases transparency and comparability 
among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosures of key 
information about leasing arrangements. The guidance is effective for reporting periods beginning after December 15, 2018. 

35

ASU 2016-02 mandates a modified retrospective transition method. We are currently assessing the impact this guidance will 
have on our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows – Classification of Certain Cash Receipts 

and Cash Payments. ASU 2016-15 provides guidance on the presentation and classification of specific cash flow items to 
improve consistency within the statement of cash flows. This guidance is effective for fiscal years, and interim periods within 
those fiscal years beginning after December 15, 2017, with early adoption permitted. We are evaluating the effect that ASU 
2016-15 will have on our consolidated financial statements and related disclosures.

In October 2016, the FASB issued ASU No. 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory,” which 

requires an entity to immediately recognize the tax consequences of intercompany transfer other than inventory. The guidance 
is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are 
assessing the impact this guidance will have on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, “Restricted Cash,” which is intended to reduce the diversity in the 

classification and presentation of changes in restricted cash in the statement of cash flows, by requiring entities to combine the 
changes in cash and cash equivalents and restricted cash in one line. As a result, entities will no longer present transfers 
between cash and cash equivalents and restricted cash in the statement of cash flows. In addition, if more than one line item is 
recorded on the balance sheet for cash and cash equivalents and restricted cash, a reconciliation between the statement of cash 
flows and balance sheet is required. This ASU is effective for annual and interim reporting periods beginning after December 
15, 2017, and early adoption was permitted. The retrospective transition method, requiring adjustment to all comparative 
periods presented, is required. We are assessing the impact this guidance will have on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles—Goodwill and Other (Topic 350): Simplifying the 

Test for Goodwill Impairment”. This accounting standards update changes the procedural steps in applying the goodwill 
impairment test. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair 
value, not to exceed the carrying amount of goodwill. The guidance is effective prospectively for annual and interim periods 
beginning after December 15, 2019, with early adoption permitted. We are currently assessing the impact this guidance will 
have on our consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation: Scope of Modification 
Accounting,” which clarifies and aims to reduce the cost and complexity when applying the stock compensation modification 
accounting guidance. The amendments in this update provide guidance about which changes to the terms or conditions of a 
share-based payment award require an entity to apply modification accounting. ASU 2017-09 will be effective for public 
companies for fiscal years beginning after December 15, 2017, including interim periods. Early adoption is permitted. We are 
currently assessing the impact this guidance will have on our consolidated financial statements.

US Sales. Net sales totaled $123.2 million for the year ended December 31, 2017, a 9% decrease from $136.1 million in 
the year ended December 31, 2016. This decrease was driven by AFX product due to slower than expected customer recapture 
and sales force attrition partially offset by strong sales growth for the Ovation System.

International Sales. Net sales of products in our international regions totaled $57.9 million for the year ended 

December 31, 2017, a 2% increase from $56.8 million in the year ended December 31, 2016. Both AFX and Ovation product 
lines posted strong growth which was offset by a decline in Nellix sales reflecting the refined IFU. Our international sales for 
the year ended December 31, 2017 included a favorable currency impact of approximately $0.4 million when compared to the 
net sales for the year ended December 31, 2016, which had a 0.8% favorable impact on growth rate representing constant 
currency increase of 1.2%.

2016. The year ended December 31, 2016 included an $8.2 million impact of purchase price accounting for inventory acquired 
in the TriVascular merger. Excluding this impact, cost of goods sold decreased by $1.1 million in the year ended December 31, 
2017 versus 2016. This decrease is driven by lower revenue.

Research and development. The $11.3 million decrease in research and development expenses as compared to the prior 

year period was attributable to the timing of project spending and synergies related to the TriVascular merger.

Clinical and regulatory affairs. The $3.3 million decrease in clinical and regulatory affairs expenses as compared to the 

prior year period was due to synergies related to the TriVascular merger.

Marketing and sales.  The $15.4 million decrease in marketing and sales expenses as compared to the prior year period 

was due to synergies related to the TriVascular merger.

General and administrative.  The $5.7 million decrease in general and administrative expenses as compared to the prior 

year period was primarily attributable to a decrease in headcount related to synergies as a result of the TriVascular merger.  The 
targeted reductions were initiated to provide efficiencies and realign resources as well as to allow for continued investment in 
strategic areas and drive growth.

Restructuring costs. The $9.6 million decrease in restructuring costs for the year ended December 31, 2017 was driven by 
fiscal year 2016 costs associated with TriVascular executive change in control agreements, and severance and retention bonuses 
resulting from the TriVascular merger.

US Sales. Net sales totaled $136.1 million for the year ended December 31, 2016, a 27% increase from 107.2 million in 

the year ended December 31, 2015. This increase was driven by sales contributed from products acquired as part of the 
TriVascular merger offset by the impact of the AFX and AFX2 products hold in the quarter ended December 31, 2016.

International Sales. Net sales of products in our international regions totaled $56.8 million for the year ended December 

31, 2016, a 22% increase from $46.4 million in the year ended December 31, 2015, primarily due to sales contributed from 
products acquired as part of the TriVascular merger. Our international sales for the year ended December 31, 2016 included the 
impact from the temporary AFX CE Mark suspension along with the AFX and AFX2 products hold in the quarter 
ended December 31, 2016.

Net sales contributed from products acquired as part of the TriVascular merger totaled $40.0 million for the year ended

an increase in headcount related to the TriVascular merger, higher professional fees and stock-based compensation.

Restructuring costs. The $11.1 million increase in restructuring costs for the year ended December 31, 2016 is comprised 
of costs associated with TriVascular executive change in control agreements, severance and retention bonuses as a result of the

Our income tax expense was $0.5 million and our effective tax rate was (0.3)% for the twelve months ended 
December 31, 2016 due to our tax positions in various jurisdictions. Our income tax benefit of $9.3 million for the twelve

months ended December 31, 2015 was due to our recognition of a deferred tax liability of $9.6 million as a result of the 
temporary difference between the carrying value and the tax basis of the 3.25% Senior Notes. This liability which was recorded 
as an adjustment to the additional paid-in capital resulted in a reduction of our valuation allowance which was recorded as a 
benefit to income tax expense in 2015. During the twelve months ended December 31, 2016 and 2015, we had operating legal 
entities in the United States, Canada, Italy, New Zealand, Poland and the Netherlands (including registered sales branches in

Operating Activities

Cash used in operating activities was $38.5 million for the year ended December 31, 2017, as compared to cash used in 
operating activities of $74.8 million in the prior year period. For the twelve months ended December 31, 2017, the decrease in 
cash usage was primarily due to (i) the decreased net loss of $66.4 million, (ii) noncash stock-based compensation of $11.6 
million, (iii) non-cash accretion of interest on convertible note of $10.2 million, (iv) depreciation and amortization of $9.1 
million, (v) a decrease in accounts receivable and other receivables of $4.8 million, (vi) an increase in accrued expenses and 
other current liabilities of $4.4 million, (vii) an increase in accrued expenses and other current liabilities of $4.4 million and 
(viii) non-cash loss on debt extinguishment of $4.0 million. These decreases in cash usage were partially offset by a decrease in 
accrued payroll of $5.2 million, an increase in inventory expenditures of $3.0 million, a decrease in accounts payable of $1.8 
million, and a decrease in prepaid expenses and other current assets of $1.0 million.

During the twelve months ended December 31, 2017 and 2016, our cash collections from customers totaled $186.8 
million and $193.9 million, respectively, representing 103% and 101%, respectively, of reported revenue for the same periods.

Investing Activities

Cash provided by investing activities for the twelve months ended December 31, 2017 was $19.8 million, as compared to 
the cash used in investing activities of $28.5 million in the prior period. For the twelve months ended December 31, 2017, cash 
provided by investing activities consisted of $21.0 million from the proceeds from maturities of marketable securities, offset by 
$1.2 million used for machinery and equipment purchases. Cash used in investing activities for the twelve months 
ended December 31, 2016 was $28.5 million and consisted of $60.6 million used for the acquisition of TriVascular, $21.0 
million used to purchase marketable securities and $2.8 million used for machinery and equipment purchases. This is offset by 
proceeds from the maturities of marketable securities of $55.9 million.

Financing Activities

Cash provided by financing activities was $49.7 million for the twelve months ended December 31, 2017, as compared to 
cash provided by financing activities of $5.3 million in the prior year period. For the twelve months ended December 31, 2017, 
cash provided by financing activities consisted of $120.0 million from the proceeds from issuance of debt, $3.1 million from 
the exercise of stock options and proceeds from sales of common stock under our employee stock purchase plan; offset 
by $66.6 million used to repay debt and $6.8 million used to pay deferred financing costs. Cash provided by financing activities 
for the twelve months ended December 31, 2016 consisted of proceeds of $6.3 million from the exercise of stock options and 
proceeds from sales of common stock under our employee stock purchase plan; offset by deferred financing costs of $0.9 
million, and $0.1 million used to pay minimum tax withholdings on behalf of employees for restricted stock units vested during 
the period.

Year Ended December 31, 2016 versus December 31, 2015 

         Operating Activities

Cash used in operating activities was $74.8 million for the year ended December 31, 2016, as compared to cash used in 
operating activities of $31.1 million in the prior year period. The increase in cash usage was primarily due to (i) the increased 
net loss of $154.7 million, (ii) an increase in accounts receivable and other receivables of $2.9 million and (iii) a decrease in 
accounts payable of $5.2 million. These increases in cash usage were partially offset by non-cash stock-based compensation 
of $12.3 million, depreciation and amortization of $9.1 million, an increase in accrued payroll of $7.1 million, a decrease in 
inventory expenditures of $3.5 million, an increase in accrued expenses and other current liabilities of $2.9 million, non-cash 
accretion of interest on convertible note of $9.5 million, and change in fair value of derivative non-cash of $43.8 million.

During the twelve months ended December 31, 2016 and 2015, our cash collections from customers totaled $193.9 

million and $152.7 million, respectively, representing 101% and 99% of reported revenue for the same periods.

Investing Activities

Cash used in investing activities for the twelve months ended December 31, 2016 was $28.5 million, as compared the 
cash provided by inventing activities of $2.9 million in the prior period. For the twelve months ended December 31, 2016, cash 
used in investing activities consisted of $60.6 million used for the acquisition of TriVascular, $21.0 million used to purchase 
marketable securities and $2.8 million used for machinery and equipment purchases. This is offset by proceeds from the 
maturities of marketable securities of $55.9 million. Cash provided by investing activities for the twelve months 
ended December 31, 2015 was $2.9 million and consisted of proceeds from maturity of marketable securities of $89.7 million. 
This is offset by (i) purchases of marketable securities of $82.6 million and (ii) machinery and equipment purchases for $4.2 
million.

Financing Activities
Cash provided by financing activities was $5.3 million for the twelve months ended December 31, 2016, as compared to 

cash provided by financing activities of $126.7 million in the prior year period. For the twelve months ended December 31, 
2016, cash provided by financing activities consisted of $6.3 million from the exercise of stock options and proceeds from sales 
of common stock under our employee stock purchase plan, offset by $0.9 million used to pay deferred financing costs and $0.1 
million used to pay minimum tax withholdings on behalf of employees for restricted stock units vested during the period. Cash 
provided by financing activities for twelve months ended December 31, 2015 consisted of (i) proceeds of $5.8 million from the 
exercise of stock options and proceeds from sales of common stock under our employee stock purchase plan; and (ii) net 
proceeds from issuance of convertible debt of $121.4 million, offset by $0.5 million used to pay minimum tax withholdings on 
behalf of employees for restricted stock units vested during the period.

Credit Arrangements
See Note 6 of the Notes to the Consolidated Financial Statements. As of December 31, 2017, the Company was not in 

compliance with the required minimum net revenue threshold set forth in the Credit Agreement. On January 5, 2018, the 
Company delivered a notice of termination to Deerfield for the Deerfield Revolver under the Credit and Security Agreement 
(the “Credit Agreement”), dated as of April 3, 2017. The termination of the Deerfield Revolver was effective on January 12, 
2018 (the “Termination Date”) and required the Company to pay $1.3 million in termination fees.

Future Capital Requirements
We believe that the future growth of our business will depend upon our ability to successfully develop new technologies 

for the treatment of aortic disorders and successfully bring these technologies to market. We expect to incur significant 
expenditures in completing product development and clinical trials for our products. In addition, as a result of the completion of 
the merger with TriVascular, our future capital requirements are expected to increase.

The timing and amount of our future capital requirements will depend on many factors, including:

• 
• 

• 
• 

the need for working capital to support our sales growth;
the need for additional capital to fund future development programs;

the need for additional capital to fund our sales force expansion;
the need for additional capital to fund strategic acquisitions;

•  our requirements for additional facility space or manufacturing capacity;
•  our requirements for additional information technology infrastructure and systems; and

•  adverse outcomes from potential litigation and the cost to defend such litigation.

We believe that our world-wide cash resources are adequate to operate our business. We presently have several operating 
subsidiaries outside of the United States As of December 31, 2017, these subsidiaries hold an aggregate $7.3 million in foreign 
bank accounts to fund their local operations. These balances related to undistributed earnings, are deemed by management to be 
permanently reinvested in the corresponding country in which our subsidiary operates. Management has no present or planned 
intention to repatriate foreign earnings into the United States However, in the event that we require additional funds in the 
United States and may have to repatriate any foreign earnings to meet those needs, we would then need to accrue, and 
ultimately pay, incremental income tax expenses on such “deemed dividend,” unless we then have sufficient net operating 
losses to offset this potential tax liability. 

If we require additional financing in the future, it may not be available on commercially reasonable terms, or at all. Even 

if we are able to obtain financing, it may cause substantial dilution (in the case of an equity financing), or may contain 
burdensome restrictions on the operation of our business (in the case of debt financing). If we are not able to obtain required 
financing, we may need to curtail our operations and/or our planned product development.

    Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements (except for operating leases) that provide financing, liquidity, market or credit 
risk support, or involve derivatives.  In addition, we have no arrangements that may expose us to liability that are not expressly 
reflected in the accompanying Consolidated Financial Statements.

As of December 31, 2017, we did not have any relationships with unconsolidated entities or financial partnerships, often 

referred to as “structured finance” or “special purpose entities,” established for the purpose of facilitating off-balance sheet 
arrangements or other contractually narrow or limited purposes. As such, we are not subject to any material financing, liquidity, 
market or credit risk that could arise if we had engaged in such relationships.

Item 7A. 

Quantitative and Qualitative Disclosures About Market Risk

We do not believe that we currently have material exposure to interest rate or foreign currency transaction risks.

Interest Rate Risk and Market Risk. We do not use derivative financial instruments in our investment portfolio. We are 

averse to principal loss and try to ensure the safety and preservation of our invested funds by limiting default risk, market risk, 
and reinvestment risk. We attempt to mitigate default risk by investing in only high credit quality securities and by positioning 
our portfolio to appropriately respond to a significant reduction in the credit rating of any investment issuer or guarantor.

We were exposed to market risk for changes in interest rates on the MidCap Credit Facility. All outstanding amounts 
under the MidCap Credit Facility bore interest at a variable rate equal to LIBOR, plus 4.10%. On April 3, 2017, we replaced the 
MidCap Credit Facility with a new revolving line of credit with Deerfield ELGX Revolver, LLC (“Deerfield Revolver”), 
pursuant to which the Company may borrow up to the lesser of $50 million or its applicable borrowing base from time to time 
prior to March 31, 2020 (the “Revolver”) and paid $2.5 million in termination fees to MidCap. All outstanding principal under 
the Revolver bore interest at a rate equal to 3-month LIBOR (with a 1% floor) plus 4.60%. On January 5, 2018, the Company 
delivered a notice of termination to Deerfield, for the Deerfield Revolver under the Credit and Security Agreement (the “Credit 
Agreement”), dated as of April 3, 2017. The termination of the Credit Agreement was effective on January 12, 2018 (the 
“Termination Date”) following payment by the Company of approximately $1.3 million in termination fees and related fees and 
expenses. The Company decided to terminate the Credit Agreement after it determined that it had failed to satisfy the required 
minimum net revenue threshold set forth in the Credit Agreement for the twelve months ended December 31, 2017. There are 
no borrowings currently outstanding under the Credit Agreement. 

Our 3.25% Senior Notes, 2.25% Senior Notes and Term Loan bear fixed interest rates, and therefore, would not be subject 

to interest rate risk. The capped call transactions are derivative instruments that qualify for classification within stockholders’ 
equity because they meet an exemption from mark-to-market derivative accounting. The settlement amounts for the capped call 
transactions are each determined based upon the difference between a strike price and a traded price of our common stock.

Foreign Currency Transaction Risk. While a majority of our business is denominated in the United States dollar, a portion 

of our revenues and expenses are denominated in foreign currencies. Fluctuations in the rate of exchange between the United 
States dollar and the Euro or the British Pound Sterling may affect our results of operations and the period-to-period 
comparisons of our operating results. Foreign currency transaction gains and losses are caused by transactions denominated in a 
currency other than the functional currency and must be remeasured at each balance sheet date or upon settlement. Foreign 
currency transaction realized and unrealized gains and losses resulted in approximately $0.7 million of gain in 2017, primarily 
related to intercompany payables and receivables associated with our European operations. We expect to continue to limit our 
exposure through future settlements.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Endologix, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Endologix, Inc. and subsidiaries (the “Company”) as of 
December 31, 2017 and 2016, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, 
and cash flows for each of the years in the three year period ended December 31, 2017, and the related notes and financial 
statement schedule of valuation and qualifying accounts (collectively, the “consolidated financial statements”). In our opinion, 
the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three year period 
ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in 
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission, and our report dated March 13, 2018 expressed an unqualified opinion on the effectiveness of the Company’s 
internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws 
and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 
consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, 
as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a 
reasonable basis for our opinion.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors
Endologix, Inc.:

Opinion on Internal Control Over Financial Reporting 

We have audited Endologix, Inc. and subsidiaries’ (the “Company”) internal control over financial reporting as of 
December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, 
effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related consolidated 
statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the years in the three-year 
period ended December 31, 2017, and the related notes and financial statement schedule of valuation and qualifying accounts 
(collectively, the “consolidated financial statements”), and our report dated March 13, 2018 expressed an unqualified opinion 
on those consolidated financial statements.

Basis for Opinion 

The Company’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 
Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on 
the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws 
and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. 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 of internal control over financial reporting included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (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.

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

ENDOLOGIX, INC.

1. Description of Business, Basis of Presentation, and Operating Segment

(a) Description of Business

Endologix, Inc. (the “Company”) is a Delaware corporation with corporate headquarters in Irvine, California and production 

facilities located in Irvine and Santa Rosa, California. The Company develops, manufactures, markets, and sells innovative 
medical devices for the treatment of aortic disorders. The Company’s products are intended for the treatment of abdominal aortic 
aneurysms (“AAA”). The Company’s AAA products are built on two platforms: (1) traditional minimally-invasive endovascular 
repair (“EVAR”) and (2) endovascular sealing (“EVAS”), the Company’s innovative solution for sealing the aneurysm sac while 
maintaining blood flow through two blood flow lumens. The Company’s current EVAR products include the Ovation® 
Abdominal Stent Graft System (“Ovation”), Endologix AFX Endovascular AAA System (“AFX”), the VELA™ Proximal 
Endograft System (“VELA”) and the Endologix IntuiTrak Endovascular AAA System (“IntuiTrak”). The Company’s current 
EVAS product is the Nellix Endovascular Aneurysm Sealing System (“Nellix EVAS System”). Sales of the Company’s EVAR 
and EVAS platforms (including extensions and accessories) to hospitals in the United States and Europe, and to third-party 
international distributors, provide the sole source of the Company’s reported revenue.

(b) Basis of Presentation

The accompanying Consolidated Financial Statements in this Annual Report on Form 10-K have been prepared in 
accordance with generally accepted accounting principles in the United States of America (“GAAP”) and with the rules and 
regulations of the United States Securities and Exchange Commission (“SEC”). These financial statements include the financial 
position, results of operations, and cash flows of the Company, including its subsidiaries, all of which are wholly-owned. All 
inter-company accounts and transactions have been eliminated in consolidation. For years ended December 31, 2017, 2016, and 
2015 there were no related party transactions.  

In August 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-15, “Disclosure of Uncertainties 
About an Entity's Ability to Continue as a Going Concern.” ASU 2014-15 explicitly requires management to assess an entity's 
ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. ASU 2014-15 is 
intended to define management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue 
as a going concern and to provide related footnote disclosures. The new standard is effective for all entities in the first annual 
period ending after December 15, 2016 and for annual periods and interim periods thereafter. We have adopted the guidance for 
the year ended December 31, 2016. The adoption of ASU 2014-15 did not impact our disclosures.

In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs", which requires 
debt issuance costs related to a recognized debt liability to be presented on the balance sheet as a direct deduction from the debt 
liability, similar to the presentation of debt discounts. The ASU was effective for the Company on January 1, 2016. The Company 
adopted ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs" during the first quarter of 2016, utilizing 
retrospective application as permitted. As a result, the Company reclassified debt issuance costs from other assets to reduce the 
convertible notes as of December 31, 2015 and 2016. In conjunction with the Company’s adoption of ASU 2015-03, the 
Company also adopted an update thereof or ASU 2015-15 “Presentation and Subsequent Measurement of Debt Issuance Costs 
Associated with Line-of Credit Arrangements.” As a result, the Company classified debt issuance costs related to a line-of-credit 
arrangement as other assets.

In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting 

for Measurement-Period Adjustments,” which requires that an acquirer recognize adjustments to provisional amounts that are 
identified during the measurement period in the reporting period in which the adjustment amounts are determined. The new 
guidance also requires that the acquirer record, in the same period's financial statements, the effect on earnings of changes in 
depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the 
accounting had been completed at the acquisition date. The guidance is effective for fiscal years beginning after December 15, 
2015, including interim periods within those fiscal years. The Company adopted this standard and has applied it to amounts 
related to the TriVascular acquisition. 

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory,” which requires an entity to 

measure inventory within the scope of the amendment at the lower of cost and net realizable value. Net realizable value is the 
estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and 

52

transportation. We adopted this new accounting standard prospectively in the first quarter of 2017. This new accounting standard 
did not have a significant impact on our consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to 

Employee Share-Based Payment Accounting,” which modifies certain aspects of the accounting for share-based payment 
transactions, including income taxes, classification of awards, and classification in the statement of cash flows. We adopted this 
standard effective January 1, 2017. As a result, excess tax benefits are no longer recorded in additional paid-in capital and instead 
are applied against taxes payable or recognized in the consolidated statements of operations. In addition, our income tax expense 
and associated effective tax rate will be impacted by fluctuations in stock price between the grant dates and vesting dates of 
equity awards. We also determined that there were no significant changes to disclosure or financial statement presentation and 
changes in accounting for excess tax benefits and deficiencies were not material as a result of adoption. 

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with 

Customers”, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of 
promised goods or services to customers. ASU No. 2014-09 will replace most existing revenue recognition guidance in U.S. 
GAAP when it becomes effective. The FASB agreed to a one-year deferral of the revenue recognition standard's effective date for 
all entities. The new revenue standard is effective for us on January 1, 2018. Early application is permitted, but not before the 
original effective date, which would have been January 1, 2017 for us. The new revenue standard permits the use of either the full 
retrospective or modified retrospective transition method; these methods may be applied retrospectively to each prior period 
presented or retrospectively with the cumulative effect recognized as of the date of initial application.

Accordingly, in 2016, we established a cross-functional implementation team to analyze the impact of the new revenue 
standard. This preliminary analysis included the review of an initial sample of contracts, as well as reviewing current accounting 
policies and customary business practices to identify potential differences that would result from applying the requirements of the 
new standard to our revenue contracts. We currently expect revenue related to the completion of an EVAR or EVAS procedure in 
hospitals and shipments to distributors of our products, to remain substantially unchanged. As part of our review, we separated 
revenue streams into portfolios of contracts with similar characteristics and selected samples thereof, as we do not expect the 
financial statement effects to differ materially when applying this approach to individual contracts. In addition, we are in the 
process of implementing appropriate changes to our business processes, systems and controls to support recognition and 
disclosure under the new revenue standard. We currently expect to adopt the new revenue standard in our first quarter of 2018 
utilizing the modified retrospective adoption method. We continue to expect that the new revenue standard will not have a 
material impact on the amount and timing of revenue recognized in our consolidated financial statements; we also currently do 
not expect to have an adjustment to the opening balance of retained earnings under the modified retrospective adoption method in 
our first quarter of 2018 financial statements. We are also in the process of reviewing the expansion of our disclosures relating to 
the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with our customers, as required by 
the new revenue standard. We are continuing to evaluate our impact and will continue to monitor any modifications or 
interpretations communicated by the FASB that may impact any of our final assessments. 

(c) Operating Segment

The Company has one operating and reporting segment that is focused exclusively on the development, manufacture, 
marketing, and sale of EVAR and EVAS products for the treatment of aortic disorders. For the year ended December 31, 2017, all 
of the Company's revenue and related expenses were solely attributable to these activities. Substantially all of the Company's 
long-lived assets are located in the United States.

2. Use of Estimates and Summary of Significant Accounting Policies

The preparation of financial statements in conformity with GAAP requires the Company's management to make estimates 

and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of 
contingent liabilities. On an on-going basis, the Company's management evaluates its estimates, including those related to (i) 
collectibility of customer accounts; (ii) whether the cost of inventories can be recovered; (iii) the value of goodwill and intangible 
assets; (iv) realization of tax assets and estimates of tax liabilities; (v) likelihood of payment and value of contingent liabilities; 
and (vi) potential outcome of litigation. Such estimates are based on management's judgment which takes into account historical 
experience and various assumptions. Nonetheless, actual results may differ from management's estimates.

The following critical accounting policies and estimates were used in the preparation of the accompanying Consolidated 

Financial Statements:

53

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(i) Cash and Cash Equivalents

We consider all highly liquid investments that are readily convertible into cash and have a maturity of three months or less 

at the time of purchase to be cash equivalents. The cost of these investments approximates their fair value.

(ii) Marketable securities

At December 31, 2016, the Company’s investments included short-term marketable securities, which were classified as 

held-to-maturity investments as the Company had the positive intent and ability to hold the investments to maturity. These 
investments were therefore recorded on an amortized cost basis. Discounts or premiums were amortized to interest income using 
the interest method. Marketable securities are investments with original maturities of greater than 90 days. Management reviewed 
the Company’s investments as of December 31, 2016, and concluded that there were no securities with other than temporary 
impairments in the investment portfolio. The Company’s investments were matured during the year ended December 31, 2017 
and at December 31, 2017, the Company had no marketable securities.

 (ii) Accounts Receivable

 Trade accounts receivable are recorded at the invoiced amount, inclusive of applicable value-added tax ("VAT"), and do not 
bear interest.  Revenue is recorded net of VAT. The allowance for doubtful accounts is management's best estimate of the amount 
of probable credit losses in existing accounts receivable. Account balances are charged off against the allowance after appropriate 
collection efforts are exhausted. 

(iii) Inventories

The Company values inventory at the lower of the actual cost to purchase or manufacture the inventory, or net realizable 
value for such inventory. Cost is determined on the first-in, first-out method. The Company regularly reviews inventory quantities 
in process and on hand, and when appropriate, records a provision for obsolete and excess inventory. The provision is based on 
actual loss experience and a forecast of product demand compared to its remaining shelf life.

 (iv) Property and Equipment

 Property and equipment are stated at cost and depreciated on a straight-line basis over the following estimated useful lives:

Property Class
Office furniture

Computer hardware

Computer software

Useful Life
Seven years

Three years

Three to eight years

Production equipment and molds
Leasehold improvements

Three to seven years
Shorter of expected useful life or remaining term of lease

Upon sale or disposition of property and equipment, any gain or loss is included in the accompanying Consolidated 
Statements of Operations and Comprehensive Loss.  Property and equipment are tested for impairment only when impairment 
indicators are present. 

(v) Goodwill and Intangible Assets

Intangible assets with definite lives are amortized over their estimated useful lives using a method that reflects the pattern 

over which the economic benefit is expected to be realized, and is as follows:

Intangible Asset Class
Goodwill
Trademarks and tradenames

Developed technology
Customer relationships

Useful Life
Indefinite lived
Indefinite lived
Eleven to thirteen years
Ten years

In-process research and development will be amortized upon commencement of commercial sales and it is expected to be 

amortized over its useful life.

54

 
ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are tested for impairment 
annually or whenever events or changes in business circumstances suggest the potential of an impairment. Under the FASB 
guidance, the evaluation of indefinite-lived intangible assets for impairment allows for a qualitative assessment to be performed, 
which is similar to the FASB guidance for evaluating goodwill for impairment. In performing these qualitative assessments, the 
Company considered relevant events and conditions, including but not limited to: macroeconomic trends, industry and market 
conditions, overall financial performance, cost factors, company-specific events, legal and regulatory factors and the Company's 
market capitalization. The Company completed its annual indefinite lived intangible asset impairment test as of June 30, 2017, 
with no resulting impairment.

The Company most recently completed its annual test for impairment of  goodwill as of June 30, 2017, with no resulting 

impairment, as its market capitalization was in substantial excess of the value of its total stockholders' equity (the Company has 
one "reporting unit" for purposes of the goodwill impairment test).  

Intangible assets with finite lives are tested for impairment only when impairment indicators are present.

(vi) Fair Value Measurements

In determining the fair value of its assets and liabilities, the Company uses various valuation approaches. Fair value is 
defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market 
participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed 
based on market data obtained from independent sources (observable inputs) and (ii) an entity's own assumptions about market 
participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair 
value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for 
identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value 
hierarchy are described below: 

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted 

assets or liabilities.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly 

or indirectly, including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar 
assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., 
interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other 
means.

Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that 
the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value 
requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value 
hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair 
value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. 

The Company’s held-to-maturity securities, which are fixed income investments, are comprised of obligations of United 

States government agencies, corporate debt securities and other interest bearing securities. These held-to-maturity securities are 
recorded at amortized cost and are therefore not included in the Company’s market value measurement disclosure. Money market 
funds, which are cash and cash equivalents, are valued using quoted market prices with no valuation adjustments applied. 
Accordingly, these securities are categorized in Level 1. The recorded values of all our other financial instruments approximate 
their current fair values because of their nature and respective relatively short maturity dates or durations.      

 The recorded values of all our accounts receivable and accounts payable approximate their current fair values because of 

their nature and respective relatively short maturity dates or durations.

 (vii) Contingent Consideration for Business Acquisition

The Company's management determined the fair value of contingently issuable common stock on the Nellix acquisition date 

(see Note 9) using a probability-based income approach with an appropriate discount rate (determined using both Level 1 and 
Level 3 inputs). Changes in the fair value of this contingently issuable common stock are determined at each period end and are 
recorded in the other income (expense) section of the accompanying Consolidated Statements of Operations and Comprehensive 
Loss, and the current and non-current liabilities section of the accompanying Consolidated Balance Sheets.

  (viii) Revenue Recognition

55

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

The Company recognizes revenue when all of the following criteria are met:

•  
•  

•  

•  

Appropriate evidence of a binding arrangement exists with the customer;
The sales price for the EVAR or EVAS product (including device extensions and accessories) is established 
with the customer;

The EVAR or EVAS product has been used by the hospital in an EVAR procedure, or the distributor has 
assumed title with no right of return; and
Collection of the corresponding receivable from the customer is reasonably assured at the time of sale.

For sales made to hospitals, the Company recognizes revenue upon completion of an EVAR or EVAS procedure, when the 
EVAR or EVAS products are implanted in a patient. For sales made to distributors, the Company recognizes revenue when title 
passes, which is typically at the time of shipment, as this represents the period that the customer has assumed custody of the 
EVAR or EVAS product, without right of return, and assumed risk of loss.

The Company does not offer rights of return, other than honoring a standard warranty.

(ix) Shipping Costs

Shipping costs billed to customers are reported within revenue, with the corresponding costs reported within costs of goods 

sold.

    (x) Foreign Currency Transactions

The assets and liabilities of the Company's foreign subsidiaries are translated at the rates of exchange at the balance sheet 
date. The income and expense items of these subsidiaries are translated at average monthly rates of exchange. Gains and losses 
resulting from foreign currency transactions, which are denominated in a currency other than the respective entity’s functional 
currency are included in other income (expense), net, within the accompanying Consolidated Statements of Operations and 
Comprehensive Loss. Foreign currency translation adjustments between the respective entity's functional currency and the United 
States dollar are recorded to accumulated other comprehensive loss within the stockholders' equity section of the accompanying 
Consolidated Balance Sheets.  There were no items reclassified out of accumulated other comprehensive loss and into net loss 
during the years ended December 31, 2017, 2016, and 2015.  The only activity in the accumulated other comprehensive loss was 
related to foreign currency translation.

(xi) Income Taxes

The Company records the estimated future tax effects of temporary differences between the tax basis of assets and

liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards. The 
Company has recorded a valuation allowance to substantially reduce its net deferred tax assets, because the Company believes 
that, based upon a number of factors, it is more likely than not that substantially all the deferred tax assets will not be realized. If 
the Company were to determine that it would be able to realize additional deferred tax assets in the future, an adjustment to the 
valuation allowance on its deferred tax assets would increase net income in the period such determination was made.  In the event 
that the Company were assessed interest and/or penalties from taxing authorities, such amounts would be included in "income tax 
expense" within the Consolidated Statements of Operations and Comprehensive Loss in the period the notice was received.

    (xii) Net Loss Per Share

Net loss per common share is computed using the weighted average number of common shares outstanding

during the periods presented. Because of the net losses during the years ended December 31, 2017, 2016, and 2015, options to 
purchase the common stock, restricted stock awards, and restricted stock units of the Company were excluded from the 
computation of net loss per share for these periods because the effect would have been antidilutive.

    (xiii) Research and Development Costs

Research and development costs are expensed as incurred.

    (xiv) Product Warranty

Within six months of shipment, certain customers may request replacement of products they receive that do not meet 

product specifications; no other warranties are offered.  The Company contractually disclaims responsibility for any damages 
associated with physician's use of its EVAR or EVAS product.  Historically, the Company has not experienced a significant 
amount of costs associated with its warranty policy.

There were no remeasurements to fair value during the years ended December 31, 2017 and 2016 of financial assets and 
liabilities that are not measured at fair value on a recurring basis. There were no transfers between Level 1, Level 2, or Level 3 
securities during the years ended December 31, 2017 and 2016. 

(f) Instruments Not Recorded at Fair Value on a Recurring Basis

The Company measures the fair value of their Senior Notes carried at amortized cost quarterly for disclosure purposes. 

The estimated fair value of the Senior Notes is determined by Level 2 inputs and is based primarily on quoted market prices for 
the same or similar issues. Based on the market prices, the fair value of our Senior Notes was $131.2 million as of 
December 31, 2017 and $187.6 million as of December 31, 2016. 

The Company measures the fair value of its Term Loan carried at amortized cost quarterly for disclosure purposes. The 
estimated fair value of the Term Loan is determined by Level 3 inputs and is based primarily on unobservable inputs that are 
not corroborated by market data. The fair value of the Company's Term Loan was $101.9 million as of December 31, 2017.

Due to its short-term nature, the Company believes that the carrying value of its revolving line of credit approximated its 

fair value at December 31, 2017.

4. Stock-Based Compensation

         2015 Stock Incentive Plan

The Company has one active stockholder-approved stock-based compensation plan, the 2015 Stock Incentive Plan (the 

"2015 Plan"), which replaced the Company's former stockholder-approved plans. Incentive stock options, non-qualified 
options, restricted stock awards, restricted stock units, and stock appreciation rights may be granted under the 2015 Plan.

         The maximum number of shares of the Company's common stock available for issuance under the 2015 Plan is 9.8 
million shares. As of December 31, 2017, 0.9 million shares were available for grant. It is the Company's policy that before 
stock is issued through the exercise of stock options, the Company must first receive all required cash payment for such shares.  
The stock issuable under the Plan shall be shares of authorized new unissued shares.

         Stock-based awards are governed by agreements between the Company and the recipients. Incentive stock options and 
nonqualified stock options may be granted under the 2015 Plan at an exercise price of not less than 100% of the closing fair 
market value of the Company's common stock on the respective date of grant.  The grant date is generally the first day of 
employment for new hire grants and the date of approval for all others. Awards are approved by either a delegated member of 
the Company's Executive Management or by the Compensation Committee of the Board of Directors for awards that exceed the 
Company's Executive Management's authority.  

         The Company's standard stock-based award vests 25% on the first anniversary of the date of grant, or for new hires, the 
first anniversary of their initial date of employment with the Company. Awards vest monthly thereafter on a straight-line basis 
over three years. Stock options must be exercised, if at all, no later than 10 years from the date of grant. Upon termination of 
employment with the Company, vested stock options may be exercised within 90 days from the last date of employment.  In the 
event of an optionee's death, disability, or retirement, the exercise period is 365 days from the last date of employment.

         2017 Inducement Stock Incentive Plan

         On October 27, 2017, the Board of Directors (the “Board”) of the Company adopted the 2017 Inducement Stock Incentive 
Plan (the “2017 Inducement Plan”). The 2017 Inducement Plan provides for the grant of equity-based awards in the form of 
non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights, performance shares and 
performance units. In accordance with Nasdaq Listing Rules, awards under the 2017 Inducement Plan may only be made to an 
employee who has not previously been an employee of the Company or a member of the Board, or an employee or member of 
the board of directors of any subsidiary of the Company, or following a bona fide period of non-employment with the Company 
or any subsidiary of the Company, if he or she is granted such award in connection with his or her commencement of 
employment with the Company or a subsidiary of the Company and such grant is an inducement material to his or her entering 
into employment with the Company or such subsidiary.

         The Board has reserved 2,000,000 shares of the Company’s common stock for issuance pursuant to awards granted under 
the 2017 Inducement Plan, and the 2017 Inducement Plan will be administered by the Compensation Committee of the Board. 
As of December 31, 2017, 1.7 million shares were available for grant. 

         Employee Stock Purchase Plan

         Under the terms of the Company's Amended and Restated 2006 Employee Stock Purchase Plan, as amended (the 
"ESPP"), eligible employees can purchase common stock through payroll deductions. As of December 31, 2017, 1.0 million 
shares were available for grant. The purchase price is equal to the closing price of the Company's common stock on the first or 
last day of the offering period (whichever is less), minus a 15% discount. The Company uses the Black-Scholes option-pricing 
model, in combination with the discounted employee price, in determining the value of ESPP expense to be recognized during 
each offering period.  

         The table below summarizes the stock-based compensation recognized, common stock shares purchased by Company 
employees, and the average purchase price per share as part of the ESPP program during the years ended December 31, 2017, 
2016, and 2015.

         The Company values stock-based awards, including stock options and restricted stock, as of the date of grant (and is 
marked-to-market at each reporting period for unvested grants issued to non-employees).  

          The Company recognizes stock-based compensation expense (net of estimated forfeitures) using the straight-line method 
over the requisite or implicit service period, as applicable. Forfeitures of employee awards are estimated at the time of grant and 
the forfeiture assumption is periodically adjusted for actual employee vesting behavior. For purposes of this estimate, the 
Company has applied an estimated forfeiture rate of 11%, 11%, and 14% for the years ended December 31, 2017, 2016, and 
2015, respectively.

         Stock-Based Compensation Expense Summary

         The Company classifies related compensation expense in the accompanying Consolidated Statements of Operations and 
Comprehensive Loss, based on the Company department to which the recipient belongs. Stock-based compensation expense 
included in cost of goods sold and operating expenses for years ended December 31, 2017, 2016, and 2015 was as follows:

In addition, the Company had $0.4 million, $0.5 million, and $0.6 million of stock-based compensation capitalized in 

inventory as of December 31, 2017, 2016, and 2015, respectively.

      Valuation Assumptions

The grant-date fair value per share for restricted stock awards was based upon the closing market price of the Company’s 

common stock on the award grant-date.

The fair value of stock options granted was estimated at the date of grant using the Black-Scholes option-pricing model.  

The following assumptions were used to determine fair value for the stock awards granted in the applicable year:

Average expected option life (in years) (a)
Volatility (b)
Risk-free interest rate (c)

Dividend yield (d)

Weighted-average grant-date fair value per stock option

As discussed in Note 6, in December 2013, the Company issued $86.3 million in aggregate principal amount of 2.25% 

Convertible Senior Notes due 2018 (the “2.25% Senior Notes”) in an underwritten public offering. In October 2015, the 
Company also issued $125.0 million in aggregate principal amount of 3.25% Convertible Senior Notes due 2020 (the “3.25% 
Senior Notes”) in an underwritten public offering. Upon any conversion, the 2.25% Senior Notes and/or 3.25% Senior Notes, 
(collectively the "Senior Notes") may be settled, at the Company’s election, in cash, shares of the Company’s common stock or 
a combination of cash and shares of the Company’s common stock. For purposes of calculating the maximum dilutive impact, it 
is presumed that the Senior Notes will be settled in common stock with the resulting potential common shares included in 
diluted earnings per share if the effect is more dilutive. The effect of the conversion of the Senior Notes is excluded from the 
calculation of diluted loss per share because the impact of these securities would be anti-dilutive.

Deerfield Warrants

On April 3, 2017, the Company entered into a Facility Agreement (the “Facility Agreement”) with affiliates of Deerfield 

Management Company, L.P. (collectively, “Deerfield”), pursuant to which Deerfield agreed to loan to the Company up 
to $120.0 million, subject to the terms and conditions set forth in the Facility Agreement (the “Term Loan”). Pursuant to the 
terms of the Facility Agreement, the Company issued warrants to Deerfield to purchase an aggregate of 6,470,000 shares of 
common stock of the Company at an exercise price of $9.23 per share (the “Deerfield Warrants”). The number of shares of 
common stock of the Company into which the Warrants are exercisable and the exercise price of the Warrants will be adjusted 
to reflect any stock splits, recapitalizations or similar adjustments in the number of outstanding shares of common stock of the 
Company. Refer to Note 6 of the Notes to the Condensed Consolidated Financial Statements for further discussion.

6. Credit Facilities

2.25% Convertible Senior Notes 

On December 10, 2013, the Company issued $86.3 million in aggregate principal amount of 2.25% Senior Notes. The 

2.25% Senior Notes mature on December 15, 2018 unless earlier repurchased by the Company or converted.  The Company 
received net proceeds from the sale of the 2.25% Senior Notes of approximately $82.6 million, after deducting underwriting 
discounts and commissions and offering expenses payable by the Company. Interest is payable on the 2.25% Senior Notes on 
June 15 and December 15 of each year, beginning June 15, 2014. 

The 2.25% Senior Notes are governed by the terms of a base indenture (the “Base Indenture”), as supplemented by the 
first supplemental indenture relating to the 2.25% Senior Notes (the “First Supplemental Indenture,” and together with the Base 
Indenture, the “2.25% Senior Notes Indenture”), between the Company and Wells Fargo Bank, National Association (the 
“Trustee”), each of which were entered into on December 10, 2013.

The 2.25% Senior Notes are senior unsecured obligations and are: (a) senior in right of payment to the Company’s 

future indebtedness that is expressly subordinated in right of payment to the 2.25% Senior Notes; (b) equal in right of payment 
to the Company’s existing and future unsecured indebtedness that is not so subordinated; (c) effectively junior to any of the 
Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and (d) structurally junior 
to all existing and future indebtedness (including trade payables) incurred by the Company’s subsidiaries.

On or after December 15, 2016, the Company may redeem for cash all or any portion of the 2.25% Senior Notes, at its 

option, but only if the closing sale price of the Company’s common stock for at least 20 trading days (whether or not 
consecutive) during any 30 consecutive trading day period ending on, and including, the second trading day immediately 
preceding the date on which the Company provides notice of redemption, exceeds 130% of the conversion price on each 
applicable trading day. The redemption price will equal 100% of the principal amount of the 2.25% Senior Notes to be 
redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the 2.25% 
Senior Notes. 

Holders may convert their 2.25% Senior Notes at any time prior to the close of business on the business day 

immediately preceding September 15, 2018 only under the following circumstances: (1) during any calendar quarter 
commencing after the calendar quarter ending on March 31, 2014, if the closing sale price of the Company’s common stock, for 
at least 20 trading days (whether or not consecutive) in the period of 30 consecutive trading days ending on the last trading day 
of the calendar quarter immediately preceding the calendar quarter in which the conversion occurs, is more than 130% of the 
conversion price of the 2.25% Senior Notes in effect on each applicable trading day; (2) during the five consecutive business-
day period following any five consecutive trading-day period in which the trading price for the 2.25% Senior Notes for each 
such trading day was less than 98% of the closing sale price of the Company’s common stock on such date multiplied by the 
then-current conversion rate; (3) if the Company calls all or any portion of the 2.25% Senior Notes for redemption, at any time 
prior to the close of business on the second scheduled trading day prior to the redemption date; or (4) upon the occurrence of 
specified corporate events. On or after September 15, 2018 until the close of business on the second scheduled trading day 
immediately preceding the stated maturity date, holders may surrender their 2.25% Senior Notes for conversion at any time, 
regardless of the foregoing circumstances. 

Upon conversion, the Company will at its election pay or deliver, as the case may be, cash, shares of the Company’s 

common stock or a combination of cash and shares of the Company’s common stock.

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

The initial conversion rate will be 41.6051 shares of the Company’s common stock for each $1,000 principal amount 

of 2.25% Senior Notes, which represents an initial conversion price of approximately $24.04 per share. Following certain 
corporate transactions that occur on or prior to the stated maturity date or the Company’s delivery of a notice of redemption, the 
Company will increase the conversion rate for a holder that elects to convert its 2.25% Senior Notes in connection with such a 
corporate transaction. 

If a fundamental change (as defined in the 2.25% Senior Notes Indenture) occurs prior to the stated maturity date, 

holders may require the Company to purchase for cash all or any portion of their 2.25% Senior Notes at a fundamental change 
purchase price equal to 100% of the principal amount of the 2.25% Senior Notes to be purchased, plus accrued and unpaid 
interest to, but excluding, the fundamental change purchase date. 

The 2.25% Senior Notes Indenture contains customary terms and covenants and events of default with respect to the 

2.25% Senior Notes. If an event of default (as defined in the 2.25% Senior Notes Indenture) occurs and is continuing, either the 
Trustee or the holders of at least 25% in aggregate principal amount of the outstanding 2.25% Senior Notes may declare the 
principal amount of the 2.25% Senior Notes to be due and payable immediately by notice to the Company (with a copy to the 
Trustee). If an event of default arising out of certain events of bankruptcy, insolvency or reorganization involving the Company 
or a significant subsidiary (as set forth in the 2.25% Senior Notes Indenture) occurs with respect to us, the principal amount of 
the 2.25% Senior Notes and accrued and unpaid interest, if any, will automatically become immediately due and payable.

The Company was not required to separate the conversion option in the 2.25% Senior Notes under ASC 815, 

"Derivatives and Hedging", and has the ability to settle the 2.25% Senior Notes in cash, common stock or a combination of 
cash and common stock, at its option. In accordance with cash conversion guidance contained in ASC 470-20, "Debt with 
Conversion and Other Options", the Company accounted for the 2.25% Senior Notes by allocating the issuance proceeds 
between the liability and the equity component. The equity component is classified in stockholders’ equity and the resulting 
discount on the liability component is accreted such that interest expense equals the Company’s nonconvertible debt borrowing 
rate. The separation was performed by first determining the fair value of a similar debt that does not have an associated equity 
component. That amount was then deducted from the initial proceeds of the 2.25% Senior Notes as a whole to arrive at a 
residual amount, which was allocated to the conversion feature that is classified as equity. The initial fair value of the 
indebtedness was $66.9 million resulting in a $19.3 million allocation to the embedded conversion option. The embedded 
conversion option was recorded in stockholders’ equity and as debt discount, to be subsequently accreted to interest expense 
over the term of the 2.25% Senior Notes. Underwriting discounts and commissions and offering expenses totaled $3.7 million 
and were allocated between the liability and the equity component in proportion to the allocation of proceeds and accounted for 
as debt issuance costs and equity issuance costs, respectively. As a result, $2.9 million attributable to the indebtedness was 
recorded as deferred financing costs in other assets, to be subsequently amortized as interest expense over the term of the 2.25% 
Senior Notes, and $0.8 million attributable to the equity component was recorded as a reduction to additional paid-in-capital in 
stockholders’ equity. During the three months ended March 31, 2016, the Company adopted ASU 2015-03, "Simplifying the 
Presentation of Debt Issuance Costs" utilizing retrospective application as permitted. As a result, the Company reclassified $1.9 
million of debt issuance costs from current and non-current other assets to reduce the 2.25% Senior Notes as of December 31, 
2015.

On April 3, 2017, the Company entered into the Facility Agreement with Deerfield, pursuant to which Deerfield 

agreed to loan to the Company up to $120 million, subject to the terms and conditions set forth in the Facility Agreement. The 
Company used a portion of the proceeds from the Term Loan to repurchase $68 million aggregate principal amount of 
outstanding 2.25% Senior Notes, plus the accrued but unpaid interest thereon, from the holders thereof in privately negotiated 
transactions. Refer to the section entitled Deerfield Facility Agreement below for further discussion. The embedded conversion 
option of the 2.25% Senior Notes, which was originally recorded in additional paid-in capital, was reduced by $2.2 million. 
Additionally, $3.2 million related to the reduction of outstanding principal related to the 2.25% Senior Notes was charged to 
loss on debt extinguishment on the Company’s Consolidated Statements of Operations and Comprehensive Loss.

As of December 31, 2017, the Company had outstanding borrowings of $17.4 million, and deferred financing costs 

of $0.2 million, related to the 2.25% Senior Notes. There are no principal payments due during the term. Annual interest 
expense on these notes will range from $1.1 million to $1.5 million through maturity.

Capped Call Transactions

On December 10, 2013, in connection with the pricing of the 2.25% Senior Notes and the exercise in full of their 

overallotment option by the underwriters, the Company entered into privately-negotiated capped call transactions (the “Capped 
Call Transactions”) with Bank of America, N.A., an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated. The 
Capped Call Transactions initial conversion rate and number of options substantially corresponds to each $1,000 principal 

66

 
 
 
ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

amount of 2.25% Senior Notes. The Company used approximately $7.4 million of the net proceeds from the 2.25% Senior 
Notes offering to pay for the cost of the Capped Call Transactions. 

The Capped Call Transactions are separate transactions entered into by the Company with Bank of America, N.A., are 

not part of the terms of the 2.25% Senior Notes and will not change the holders’ rights under the 2.25% Senior Notes. The 
Capped Call Transactions have anti-dilution adjustments substantially similar to those applicable to the 2.25% Senior Notes. 
The Capped Call Transactions are derivative instruments that qualify for classification within stockholders’ equity because they 
meet an exemption from mark-to-market derivative accounting.

The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset potential cash 

payments that the Company is required to make in excess of the principal amount upon conversion of the 2.25% Senior Notes 
in the event that the market price per share of the Company’s common stock, as measured under the terms of the Capped Call 
Transactions, is greater than the strike price of the Capped Call Transactions, which initially corresponds to the $24.04 
conversion price of the 2.25% Senior Notes. If, however, the market price per share of the Company’s common stock, as 
measured under the terms of the Capped Call Transactions, exceeds the initial cap price of $29.02, there would nevertheless be 
dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price 
exceeds the cap price of the Capped Call Transactions. 

The Company will not be required to make any cash payments to Bank of America, N.A. or any of its affiliates upon 

the exercise of the options that are a part of the Capped Call Transactions, but will be entitled to receive from Bank of America, 
N.A. (or an affiliate thereof) a number of shares of the Company’s common stock and/or an amount of cash generally based on 
the amount by which the market price per share of the Company’s common stock, as measured under the terms of the Capped 
Call Transactions, is greater than the strike price of the Capped Call Transactions during the relevant valuation period under the 
Capped Call Transactions. However, if the market price of the Company’s common stock, as measured under the terms of the 
Capped Call Transactions, exceeds the cap price of the Capped Call Transactions during such valuation period under the 
Capped Call Transactions, the number of shares of common stock and/or the amount of cash the Company expects to receive 
upon exercise of the Capped Call Transactions will be capped based on the amount by which the cap price exceeds the strike 
price of the Capped Call Transactions.

For any conversions of 2.25% Senior Notes prior to the close of business on the 55th scheduled trading day 
immediately preceding the stated maturity date of the 2.25% Senior Notes, including without limitation upon an acquisition of 
the Company or similar business combination, a corresponding portion of the Capped Call Transactions will be terminated. 
Upon such termination, the portion of the Capped Call Transactions being terminated will be settled at fair value (subject to 
certain limitations), as determined by Bank of America, N.A., in its capacity as calculation agent under the Capped Call 
Transactions, which the Company expects to receive from Bank of America, N.A., and no payments will be due Bank of 
America, N.A. The capped call expires on December 13, 2018.

In connection with the Company’s repurchase of approximately $68 million aggregate principal amount of outstanding 

2.25% Senior Notes in April 2017, the Company and Bank of America, N.A. unwound the portion of the Capped Call 
Transactions relating to the repurchased 2.25% Senior Notes. These Capped Call Transactions were originally classified in 
stockholders’ equity and continued to meet the criteria for classification thereof while outstanding, and therefore were not 
subsequently measured at fair value. The Company did not pay or receive any compensation related to the unwind of the 
Capped Call Transactions. Therefore, the Company accounted for the unwind of the Capped Call Transactions by removing 
these options at their carrying value in additional paid-in capital and recording an offsetting entry to additional paid-in capital. 
As a result, the Company did not recognize any gain or loss, and the unwind had no net impact on additional paid-in capital.

3.25% Convertible Senior Notes due 2020

On November 2, 2015, the Company issued $125.0 million aggregate principal amount of 3.25% Senior Convertible 
Notes due 2020 (the “3.25% Senior Notes”). The 3.25% Senior Notes are governed by the Base Indenture, as amended and 
supplemented by the second supplemental indenture relating to the 3.25% Senior Notes (the “Second Supplemental Indenture,” 
and together with the Base Indenture, the “3.25% Senior Notes Indenture”), dated as of November 2, 2015, by and between the 
Company and the Trustee. 

The 3.25% Senior Notes are senior unsecured obligations and are: senior in right of payment to the Company’s future 
indebtedness that is expressly subordinated in right of payment to the 3.25% Senior Notes; equal in right of payment to the 
Company’s existing and future unsecured indebtedness that is not so subordinated, including the 2.25% Senior Notes; 
effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such 

67

 
 
 
 
 
ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

indebtedness; and structurally junior to all existing and future indebtedness (including trade payables) incurred by the 
Company’s subsidiaries.

The 3.25% Senior Notes accrue interest at a rate of 3.25% per year, payable semi-annually in arrears on May 1 and 

November 1 of each year, commencing May 1, 2016. The 3.25% Senior Notes mature on November 1, 2020, unless earlier 
purchased, redeemed or converted into shares of common stock in accordance with the terms of the 3.25% Senior Notes 
Indenture.

The Company may not redeem the 3.25% Senior Notes prior to November 1, 2018. On or after November 1, 2018, the 
Company may redeem for cash all or any portion of the 3.25% Senior Notes, at its option, but only if the closing sale price of 
the Company’s common stock for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day 
period ending on, and including, the second trading day immediately preceding the date on which the Company provides notice 
of redemption, exceeds 130% of the conversion price on each applicable trading day. The redemption date can be no sooner 
than 30 trading days from the date on which notice of redemption is provided to the holders, during which time, up until two 
trading days prior to the redemption, the holders may elect to convert all or a portion of the 3.25% Senior Notes into shares of 
the Company’s common stock. The redemption price will equal 100% of the principal amount of the 3.25% Senior Notes to be 
redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the 3.25% 
Senior Notes.

The 3.25% Senior Notes are convertible at the option of the holders: (1) in the calendar quarter following any quarter in 
which, for at least 20 out of the 30 consecutive trading days (whether or not consecutive) ending on the last day of the quarter, 
the closing price of the Company’s common stock is more than 130% of the then-current conversion price of the 3.25% Senior 
Notes; (2) in the five business days following any five day period in which the trading price per $1,000 note was less than 98% 
of the product of the closing sale price of the Company’s common stock and the current conversion rate; (3) in the event that the 
Company has provided notice of redemption, but no later than two trading days prior to Company’s proposed redemption date; 
or (4) upon the occurrence of specified corporate events. On or after August 1, 2020 until the close of business on the second 
scheduled trading day immediately preceding the stated maturity date, holders may surrender their 3.25% Senior Notes for 
conversion at any time, regardless of the foregoing circumstances. 

The initial conversion rate of the 3.25% Senior Notes is 89.4314 shares of the Company’s common stock per $1,000 
principal amount of the 3.25% Senior Notes, which is equivalent to an initial conversion price of approximately $11.18 per 
share. The conversion rate is subject to adjustment upon the occurrence of certain specified events. Upon conversion, the 
Company will at its election pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination 
of cash and shares of the Company’s common stock.

If a fundamental change (as defined in the 3.25% Senior Notes Indenture) occurs prior to the stated maturity date, holders 
may require the Company to purchase for cash all or any portion of their 3.25% Senior Notes at a fundamental change purchase 
price equal to 100% of the principal amount of the 3.25% Senior Notes to be purchased, plus accrued and unpaid interest.

The 3.25% Senior Notes Indenture contains customary terms and covenants and events of default with respect to the 
3.25% Senior Notes. If an event of default (as defined in the 3.25% Senior Notes Indenture) occurs and is continuing, either the 
Trustee or the holders of at least 25% in aggregate principal amount of the outstanding 3.25% Senior Notes may declare the 
principal amount of the 3.25% Senior Notes to be due and payable immediately by notice to the Company (with a copy to the 
Trustee). If an event of default arising out of certain events of bankruptcy, insolvency or reorganization involving the Company 
or a significant subsidiary (as set forth in the 3.25% Senior Notes Indenture) occurs with respect to us, the principal amount of 
the 3.25% Senior Notes and accrued and unpaid interest, if any, will automatically become immediately due and payable.

Upon issuance and through December 31, 2015, the Company was not required to separate the conversion option from the 

3.25% Senior Notes under ASC 815, "Derivatives and Hedging". However, because the Company has the ability to settle the 
3.25% Senior Notes in cash, common stock or a combination of cash and common stock, the Company applied the cash 
conversion guidance contained in ASC 470-20, "Debt With Conversion and other Options", and accounted for the 3.25% Senior 
Notes by allocating the issuance proceeds between the liability-classified debt component and a separate equity component 
attributable to the conversion option. The equity component is classified in stockholders’ equity and the resulting discount on 
the liability component is accreted such that interest expense equals the Company’s borrowing rate for nonconvertible loan 
products of similar duration. The separation was performed by first determining the fair value of a similar debt that does not 
have an associated equity component. That amount was then deducted from the initial proceeds of the 3.25% Senior Notes as a 
whole to arrive at a residual amount, which was allocated to the conversion feature that is classified as equity. The initial fair 
value of the indebtedness was $97.8 million resulting in a $27.2 million allocation to the embedded conversion option. The 
embedded conversion option was recorded in stockholders’ equity and as a debt discount, to be subsequently accreted to interest 

68

expense over the term of the 3.25% Senior Notes. Underwriting discounts and commissions and offering expenses totaled $3.7 
million and were allocated between the liability and the equity component in proportion to the allocation of proceeds and 
accounted for as debt issuance costs and equity issuance costs, respectively. As a result, $2.9 million attributable to the 
indebtedness was recorded as deferred financing costs in other assets, to be subsequently amortized as interest expense over the 
term of the 3.25% Senior Notes, and $0.8 million attributable to the equity component was recorded as a reduction to additional 
paid-in-capital in stockholders’ equity. During the three months ended March 31, 2016, the company adopted ASU 2015-03, 
"Simplifying the Presentation of Debt Issuance Costs", utilizing retrospective application as permitted. As a result, the 
Company reclassified $2.9 million of debt issuance costs from current and non-current other assets to reduce the 3.25% Senior 
Notes as of December 31, 2015.

As of December 31, 2017, the Company had outstanding borrowings of $108.1 million, and deferred financing costs of 

$1.8 million, related to the 3.25% Senior Notes. There are no principal payments due during the term. Annual interest expense 
on these 3.25% Senior Notes will range from $9.1 million to $10.7 million through maturity. 

In connection with its merger with TriVascular in February 2016, the Company issued 13.6 million shares of common 

stock as consideration to the former stockholders. As a result of the Company's issuance of such shares in the merger, the 
quantity of authorized common shares available for future issuance was reduced to a level insufficient to honor all of the 
potential common shares underlying instruments then outstanding. Such instruments include the conversion options related to 
the 3.25% Senior Notes and 2.25% Senior Notes, employee stock options, restricted stock units, contingently issuable common 
stock relating to the prior Nellix acquisition, and stock warrants. The creation of this authorized share deficiency in February 
2016 required the Company, during the first quarter of 2016, to separate as a stand-alone derivative the 3.25% Senior Notes 
conversion option and a portion of the 2.25% Senior Notes conversion option for which no authorized shares are available to 
effect share settlement in the event of a conversion. Accordingly, in February 2016 the Company re-classed $24.8 million of the 
conversion features originally recorded in stockholder’s equity of the Senior Notes to derivative liabilities which will be marked 
to market each period until the Company authorizes sufficient new common shares to alleviate the deficiency.

On June 2, 2016, the Company amended their Amended and Restated Certificate of Incorporation to increase the number 
of authorized shares of common stock from 100,000,000 to 135,000,000, which is currently at a level sufficient to alleviate the 
share deficiency. Accordingly, on June 2, 2016, the Company re-classed $68.6 million of the conversion features of the Senior 
Notes from derivative liabilities to additional paid-in capital.

For the year ended December 31, 2016, the Company recorded $43.8 million as a fair value adjustment of derivative 

liabilities. The primary factor causing the change in the fair value of the derivative liability was during the period February 3, 
2016 through June 2, 2016 when the Company's stock price increased. Adjustments to the fair value of the derivative liabilities 
are recognized within other income (expense) in the Consolidated Statements of Operations and Comprehensive Loss.

The value of the derivative liabilities were estimated using a “with” and “without” approach utilizing observable and 

unobservable inputs causing this to be a Level 3 measurement. In the “with” scenario, the value of the Senior Notes were 
estimated in a binomial lattice model that considers all terms of the Senior Notes, including the conversion features, with a 
range of probabilities and assumptions related to the timing and likelihood of the conversion features being exercised by either 
the Company or the holders of the Senior Notes. In the “without” scenario the value of the Senior Notes absent the conversion 
options were estimated. The difference between the values estimated in the “with” and “without” scenarios represents the value 
of the derivative liabilities. Changes in the value of the derivative liabilities were driven by changes in the Company’s stock 
price, expected volatility, credit spreads, and market yields.

Bank of America Line of Credit

On July 21, 2015, the Company entered into a revolving credit facility with Bank of America, N.A. (“BOA”), whereby the 

Company could borrow up to $20.0 million (the “BOA Credit Facility”). All amounts owing under the BOA Credit Facility 
would become due and payable upon its expiration on July 21, 2017. A sub-feature in the line of credit allowed for the issuance 
of up to $10.0 million in letters of credit. The BOA Credit Facility was collateralized by all of the Company's assets, except its 
intellectual property. The BOA Credit Facility could be terminated at any time during the two year term by the Company upon 
three business days’ notice. The BOA Credit Facility usage was priced at a spread over the one-, two-, three- and six-month 
LIBOR rates, and was subject to a covenant related to timely providing publicly reported information and a liquidity covenant 
tied to Unencumbered Liquid Assets ("ULA") of not less than $30.0 million. If not in default, the Company had the ability to 
reduce the ULA covenant requirement by reducing the BOA Credit Facility, with the ULA maintained at 1.5 times the BOA 
Credit Facility.

69

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

The Company terminated the BOA Credit Facility on July 29, 2016 concurrent with its entry into a credit and security 

agreement with MidCap.

MidCap Credit Facility

On July 29, 2016, the Company entered into a credit and security agreement with MidCap Financial Trust ("MidCap"), as 

agent for the lenders party thereto and as a lender, whereby the Company may borrow up to the lesser of $50.0 million or its 
applicable borrowing base of asset-based revolving loans (the “MidCap Credit Facility”). All amounts owing under the MidCap 
Credit Facility shall accrue interest at a rate equal to the LIBOR Rate plus four and one tenth percent (4.10%). For purposes of 
the MidCap Credit Facility, LIBOR Rate means a per annum rate of interest equal to the greater of (a) one half of one percent 
(0.50%) and (b) the rate determined by MidCap by dividing (i) the Base LIBOR Rate, meaning the base London interbank offer 
rate for the applicable interest period, by (ii) the sum of one minus the daily average during such interest period of the aggregate 
maximum reserve requirement then imposed under Regulation D of the Board of Governors of the Federal Reserve System for 
Eurocurrency Liabilities (as defined therein). 

The MidCap Credit Facility was secured by substantially all of the Company's assets, excluding its intellectual property 

(“Collateral”), and placed customary limitations on indebtedness, liens, distributions, acquisitions, investments, and other 
activities of the Company in a manner designed to protect the Collateral. 

Deferred financing costs directly related to the MidCap Credit Facility such as legal, origination, and professional services 

fees totaled $0.9 million. In conjunction with the Company’s adoption of ASU 2015-03 “Simplifying the Presentation of Debt 
Issuance Costs” during the first quarter of 2016, the Company also adopted an update thereof or ASU 2015-15 “Presentation 
and Subsequent Measurement of Debt Issuance Costs Associated with Line-of Credit Arrangements.” As a result, $0.9 
million attributable to the MidCap Credit Facility was recorded as deferred financing costs in other assets, to be subsequently 
amortized as interest expense over the term of the MidCap Credit Facility. The MidCap Credit Facility also contained a lockbox 
arrangement clause requiring the Company to maintain a lockbox bank account in favor of the MidCap Credit Facility; 
Company cash receipts remitted to the lockbox bank account were swept on a regular basis to reduce outstanding borrowings 
related to the MidCap Credit Facility.

In conjunction with the Company’s termination of the BOA Credit Facility and concurrent entry into a credit and security 

agreement with MidCap in July 2016, the Company entered into a corporate credit card agreement whereby the Company is 
required to maintain a $2.0 million deposit in favor of the credit card issuer. The deposit account related to these credit cards 
will be presented as restricted cash on the Company’s Consolidated Balance Sheets.

On April 3, 2017, the Company replaced the MidCap Credit Facility with a new revolving line of credit with Deerfield 

ELGX Revolver, LLC. As a result, the Company wrote off approximately $0.8 million in deferred financing costs and was 
required to pay a $2.5 million termination fee to Midcap; the foregoing were charged to loss on debt extinguishment on the 
Company’s Consolidated Statements of Operations and Comprehensive Loss.

Deerfield Facility Agreement

On April 3, 2017 (“the Agreement Date”), the Company entered into a Facility Agreement (the “Facility Agreement”) 

with affiliates of Deerfield Management Company, L.P. (collectively, “Deerfield”), pursuant to which Deerfield agreed to loan 
to the Company up to $120.0 million, subject to the terms and conditions set forth in the Facility Agreement (the “Term Loan”). 
The Company drew the entire principal amount of the Term Loan on the Agreement Date. The Company agreed to pay 
Deerfield a yield enhancement fee equal to 2.25% of the principal amount of the funds disbursed on the Agreement Date. The 
Company also agreed to reimburse Deerfield for all reasonable out-of-pocket expenses incurred by Deerfield in connection with 
the negotiation and documentation of the Facility Agreement up to a capped amount. Accordingly, deferred financing costs of 
$5.1 million was recorded on the Company’s Consolidated Balance Sheets as a direct reduction of the Term Loan, to be 
subsequently amortized as interest expense over the effective period of the Term Loan. Concurrently with entering into the 
Facility Agreement, the Company entered into a Guaranty and Security Agreement with Deerfield (the “Security Agreement”), 
pursuant to which, as security for the repayment of the Company’s obligations under the Facility Agreement, the Company 
granted to Deerfield a first priority security interest in substantially all of the Company’s assets including intellectual property, 
with the priority of such security interest being pari passu with the security interest granted pursuant to the Facility Agreement.

70

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

Any amounts drawn under the Facility Agreement accrue interest at a rate of 6.87% per annum, payable quarterly in 

arrears beginning on July 1, 2017 and on the first business day of each calendar quarter thereafter and on the Maturity Date, 
unless repaid earlier. The Company will be required to pay Deerfield on each of April 2, 2021, April 2, 2022 and April 2, 2023 
(the “Maturity Date”), an amortization payment equal to $40 million (or, if on the Maturity Date, the remaining outstanding 
principal amount of the Term Loan).

Upon a change of control of the Company, if the acquirer satisfies certain conditions set forth in the Facility Agreement, 

such acquirer may assume the outstanding principal amount under the Facility Agreement without penalty. If such acquirer does 
not satisfy the conditions set forth in the Facility Agreement, Deerfield may, at its option, require the Company to repay the 
outstanding principal balance under the Facility Agreement plus, depending on the timing of the change of control transaction, 
the Company may be required to pay a make-whole premium and will be required to pay a change of control fee.

At any time on or after the fourth anniversary of the Agreement Date, the Company has the right to prepay any amounts 

owed under the Facility Agreement without premium or penalty, unless such prepayment occurs in connection with a change of 
control of the Company, in which case the Company must pay Deerfield a change of control fee unless such change of control 
occurs beyond a certain period after the Maturity Date. At any time prior to the fourth anniversary of the Agreement Date, any 
prepayment made by the Company will be subject to a make-whole premium and, if such prepayment occurs in connection with 
a change of control of the Company, a change of control fee.

Any amounts drawn under the Facility Agreement may become immediately due and payable upon customary events of 

default, as defined in the Facility Agreement, or the consummation of certain change of control transactions, as described 
above.

The Facility Agreement contains various representations and warranties, events of default, and affirmative and negative 
covenants, customary for financings of this type, including reporting requirements, requirements that the Company maintain 
timely reporting with the SEC and restrictions on the ability of the Company and its subsidiaries to incur additional liens on 
their assets, incur additional indebtedness and acquire and dispose of assets outside the ordinary course of business.

As of December 31, 2017, the Company had outstanding borrowings of $106.5 million, and deferred financing costs of 
$4.5 million, related to the Term Loan. Annual interest expense on these notes will range from $1.5 million to $12.7 million 
through maturity.

Warrants

In connection with the execution of the Facility Agreement, the Company issued to Deerfield warrants to purchase an 

aggregate of 6,470,000 shares of common stock of the Company at an exercise price of $9.23 per share (the “Deerfield 
Warrants”). The number of shares of common stock of the Company into which the Warrants are exercisable and the exercise 
price of the Warrants will be adjusted to reflect any stock splits, recapitalizations or similar adjustments in the number of 
outstanding shares of common stock of the Company.

The Warrants expire on the seventh anniversary of the Agreement Date. Subject to certain exceptions, the Warrants 
contain limitations such that the Company may not issue shares of common stock of the Company to Deerfield upon the 
exercise of the Warrants if such issuance would result in Deerfield beneficially owning in excess of 4.985% of the total number 
of shares of common stock of the Company then issued and outstanding.

The holders of the Warrants may exercise the Warrants for cash, on a cashless basis or through a reduction of an amount 

of principal outstanding under the Term Loan. In connection with certain major transactions, the holders may have the option to 
convert the Warrants, in whole or in part, into the right to receive the transaction consideration payable upon consummation of 
such major transaction in respect of a number of shares of common stock of the Company equal to the Black-Scholes value of 
the Warrants, as defined therein, and in the case of other major transactions, the holders may have the right to exercise the 
Warrants, in whole or in part, for a number of shares of common stock of the Company equal to the Black-Scholes value of the 
Warrants.

The Company measured the initial fair value of the 6,470,000 shares underlying the Deerfield Warrants at $14.3 million, 

net of issuance costs of $0.4 million, and recorded the amount in additional paid-in-capital and as a direct reduction of the Term 
Loan, to be subsequently amortized as interest expense over the effective period of the Term Loan.

Registration Rights Agreement

In connection with the Term Loan and the issuance of the Warrants, the Company entered into a Registration Rights 
Agreement with Deerfield (the “Registration Rights Agreement”). Pursuant to the terms of the Registration Rights Agreement, 
the Company agreed to file a registration statement on Form S-3  with the SEC on or prior to the 30th day following the 
Agreement Date, to register for resale the shares of common stock of the Company issuable upon the exercise of the Warrants. 
The registration statement was filed on Form S-3 on May 2, 2017.

Credit and Security Agreement

On April 3, 2017, the Company entered into a Credit and Security Agreement (the “Credit Agreement”) with Deerfield 

ELGX Revolver, LLC (“Deerfield Revolver”), pursuant to which the Company could borrow up to the lesser of $50 million or 
its applicable borrowing base from time to time prior to March 31, 2020 (the “Revolver”). Any outstanding principal under the 
Revolver will accrue interest at a rate equal to 3-month LIBOR (with a 1% floor) plus 4.60%, payable monthly in arrears on the 
first business day of the immediately succeeding calendar month and on the maturity date. The Company is subject to other fees 
in addition to interest on the outstanding principal amount under the Revolver, including in connection with an early 
termination of the Revolver. 

As described above, the Revolver replaces the Company’s $50.0 million asset-based revolving line of credit with MidCap 

Financial Trust. In conjunction with the Company’s adoption of ASU 2015-03 “Simplifying the Presentation of Debt Issuance 
Costs” during the first quarter of 2016, the Company also adopted an update thereof or ASU 2015-15 “Presentation and 
Subsequent Measurement of Debt Issuance Costs Associated with Line-of Credit Arrangements.” As a result, the Company 
recorded $1.2 million in deferred financing costs related to the Revolver and presents these costs as a deferred asset, to be 
subsequently amortized as interest expense over the term of the Revolver, on the Company’s Consolidated Balance Sheets. The 
Company’s obligations under the Credit Agreement are secured by a first priority security interest in substantially all of the 
Company’s assets including intellectual property, with the priority of such security interest being pari passu with the security 
interest granted pursuant to the Term Loan. As of December 31, 2017, the Company had outstanding borrowings of $21 
thousand under, and deferred financing costs of $1.0 million related to, the Revolver. 

In conjunction with the Company’s entry into the Credit Agreement, the Company entered into a corporate credit card 
agreement whereby the Company is required to maintain a $2.0 million deposit in favor of the credit card issuer. The deposit 
account related to these credit cards will be presented as restricted cash on the Company’s Consolidated Balance Sheets.

As of December 31, 2017, the Company was not in compliance with the required minimum net revenue threshold set forth 

in the Credit Agreement. On January 5, 2018, the Company delivered a notice of termination to Deerfield for the Deerfield 
Revolver under the Credit and Security Agreement (the “Credit Agreement”), dated as of April 3, 2017. The termination of the 
Deerfield Revolver was effective on January 12, 2018 (the “Termination Date”) and required the Company to pay $1.3 million 
in termination fees.

Facilities rent expense in 2017, 2016 and 2015 was $3.4 million, $3.3 million, and $2.3 million, respectively.

On June 12, 2013, the Company entered into a lease agreement for two adjacent office, research and development, and 

manufacturing facilities in Irvine, California. The premises consist of approximately 129,000 combined square feet. The lease 
has a 15-year term beginning January 1, 2014 and provides for one optional 5 year extension. The initial base rent under the 
lease is $1.9 million per year, payable in monthly installments, and escalates by 3% per year for years 2015 through 2019, and 
4% per year for years 2020 and beyond. The Company received a rent abatement for the first nine months of the lease. These 
premises replaced the Company's previous Irvine facilities. The terms of this lease agreement provide for $6.8 million of 
landlord-funded improvements (and certain other allowances) to this facility, in order to best suit the Company's requirements. 

The Company's Rosmalen facility is an administrative office of approximately 2,900 square feet and in August 2015, the 

Company extended the lease term for the Rosmalen facility until December 2020.

In conjunction with the TriVascular merger, the Company assumed the lease for TriVascular's facility in Santa Rosa, 

California. The facility is being used for manufacturing, research & development, and administrative purposes and consists 
of 110,000 square feet under an operating lease scheduled to expire in February 2023, which may be renewed for an additional 
five years.

(b) Employment Agreements and Retention Plan

On February 1, 2014, the Company entered into new employment agreements with certain of its executive officers under 

which payment and benefits would become payable in the event of termination by the Company for any reason other than cause, 
death or disability or termination by the employee for good reason (collectively, an “Involuntary Termination”) prior to, upon or 
following a change in control of the Company. The severance payment will generally be in a range of six to eighteen months of 
the employee’s then current salary for an Involuntary Termination prior to a change in control of the Company, and will 
generally be in a range of eighteen to twenty-four months of the employee’s then current salary for an Involuntary Termination 
upon or following a change in control of the Company.

(c) Legal Matters

    We are from time to time involved in various claims and legal proceedings of a nature we believe is normal and incidental 

to a medical device business. These matters may include product liability, intellectual property, employment, and other general 
claims. Such cases and claims may raise complex factual and legal issues and are subject to many uncertainties, including, but 
not limited to, the facts and circumstances of each particular case or claim, the jurisdiction in which each suit is brought, and 
differences in applicable law. We accrue for contingent liabilities when it is probable that a liability has been incurred and the 
amount can be reasonably estimated. The accruals are adjusted periodically as assessments change or as additional information 
becomes available. 

LifePort Sciences LLC v. Endologix, Inc.

On December 28, 2012, LifePort Sciences, LLC (“LifePort”) filed a complaint against the Company in the United States 

District Court, District of Delaware, alleging that certain of the Company's products infringe United States Patent Nos. 
5,489,295, 5,676,696, 5,993,481, 6,117,167, 6,302,906, and 8,192,482, which were alleged to be owned by LifePort. On March 
17, 2016, the Company entered into a Settlement and Patent License Agreement with LifePort (the “Settlement Agreement”) 
whereby LifePort granted the Company license rights to patents in exchange for a settlement of $4.7 million. The Settlement 

73

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

Agreement resolves this litigation and fully and finally releases the Company and LifePort from any claims arising out of or in 
connection with the litigation or the subject patents. The Settlement Agreement also contained a covenant not to sue for other 
patents owned by LifePort. However, since the subject patents were all expired and the Company was not currently using and 
has no plans to use the other patents owned by LifePort in products that could reach technological feasibility during the covenant 
not to sue period, there is no alternative future use and the full amount was recorded as settlement costs in the accompanying 
Consolidated Statements of Operations and Comprehensive Loss.

Steven M. Ortiz v. Endologix, Inc.  

On September 9, 2016, former employee Steven M. Ortiz filed a class action lawsuit against the Company in Orange 

County Superior Court, claiming the Company’s failure to pay all overtime wages owing; failure to provide meal periods and 
failure to pay meal period premiums; failure to pay all wages owed at time of termination seeking waiting time penalties under 
Labor Code section 203; failure to provide accurate wage statements; and violations of Business and Professions Code section 
17200 and alleging claims for penalties under the Private Attorneys General Act of 2004.  While the Company contests the 
allegations asserted in the litigation, a mediation was held on February 24, 2017 at which time the parties agreed to settle the 
case for $750,000.  The court has given final approval to the settlement agreement and the settlement funds have been deposited 
with the class administrator.  It is anticipated that the court will enter final judgment in this case in March 2018, which will 
officially conclude this litigation.

Stockholder Securities Litigation

In January 2017, two stockholders purporting to represent a class of persons who purchased the Company’s securities 

between August 2, 2016 and November 16, 2016, filed lawsuits against the Company and certain of its officers in the United 
States District Court for the Central District of California. The lawsuits allege that the Company made materially false and 
misleading statements and failed to disclose material adverse facts about its business, operational and financial performance, in 
violation of federal securities laws, relating to U.S. Food and Drug Administration Premarket Approval for the Company’s Nellix 
EVAS System. On May 26, 2017, the plaintiffs filed an amended complaint extending the class period to include persons who 
purchased the Company’s securities between May 5, 2016 and May 18, 2017 and adding certain factual assertions and 
allegations regarding the Nellix EVAS System. The plaintiffs sought unspecified monetary damages on behalf of the alleged 
class, interest, and attorney’s fees and costs of litigation. The first lawsuit, Nguyen v. Endologix, Inc. et al., Case No. 2:17-
cv-0017 AB (PLAx) (C.D. Cal.), was consolidated with the second lawsuit, Ahmed v. Endologix, Inc. et al, Case No. 8:17-
cv-00061 AB (PLAx) (C.D. Cal.), and lead Nguyen plaintiff filed a consolidated First Amended Complaint. On December 5, 
2017, the District Court granted Endologix’s motion to dismiss lead plaintiff’s First Amended Complaint, with leave to amend.  
On January 9, 2018, lead plaintiff filed a Second Amended Complaint. The Company believes these lawsuits are without merit 
and intends to defend itself vigorously.

Stockholder Derivative Litigation

Four shareholders have filed derivative lawsuits on behalf of Endologix, the nominal plaintiff, based on allegations 

substantially similar to those alleged by lead plaintiff in Nguyen.  Those actions consist of:  Sindlinger v. McDermott et al., Case 
No. BC662280 (Los Angeles Superior Court); Abraham v. McDermott et al., Case No. 30-2018-00968971-CU-BT-CSC (Orange 
County Superior Court); and Green v. McDermott et al., Case No. 8:17-cv-01155-AB (PLAx), which has been consolidated with 
Cocco v. McDermott et al., Case No. 8:17-cv-01183-AB (PLAx) (C.D. Cal.). The Company believes these lawsuits are without 
merit and intends to defend itself vigorously.

SEC Investigation

In July 2017, the Company learned that the SEC issued a Formal Order of Investigation to investigate, among other things, 

events surrounding the Nellix EVAS System and the prospect of its FDA pre-market approval.  The Company is fully 
cooperating with the investigation, but cannot predict its outcome or the timing of the investigation’s conclusion.

(d) Contract Termination

In the year ended December 31, 2016, the Company sent notices of termination to certain of its distributors providing for 

the termination of the respective distribution agreements. In accordance with ASC No. 420 “Exit or Disposal Cost Obligations”, 
the Company expensed distributor termination costs in the period in which the written notification of termination occurred. As a 
result, the Company incurred termination costs of $2.5 million for the year ended December 31, 2016. Such termination costs 
were included in contract termination and business acquisition expenses for the year ended December 31, 2016.

9. Contingently Issuable Common Stock

On October 27, 2010, the Company, entered into an Agreement and Plan of Merger and Reorganization (the “Merger 

Agreement”) with Nepal Acquisition Corporation, a wholly-owned subsidiary of the Company (“Merger Sub”), Nellix, Inc., 
certain of Nellix’s stockholders named therein and Essex Woodlands Health Ventures, Inc., as representative of the former 
Nellix stockholders. On December 10, 2010 (the “Nellix Closing Date”), the Company completed its acquisition of Nellix, Inc., 
a pre-revenue, AAA medical device company. The purchase price consisted of 3.2 million of the Company's common shares, 
issuable to the former Nellix stockholders as of the Nellix Closing Date, then representing a value of $19.4 million. Additional 
payments, solely in the form of the Company's common shares (the “Contingent Payment”), will be made upon the 
achievement of a revenue milestone and a regulatory approval milestone (collectively, the “Nellix Milestones”).  

Under the Merger Agreement, the ultimate value of the Contingent Payment would be determined on the date that each 

Nellix Milestone is achieved. The number of issuable shares would be established using an applicable per share price, which is 
subject to a ceiling and/or floor, resulting at the closing of the merger in a potential in a maximum of 10.2 million shares 
issuable upon the achievement of the Nellix Milestones. As of the Closing Date, the fair value of the Contingent Payment was 
estimated to be $28.2 million.  

The Merger Agreement provides that, in addition to the shares of common stock of the Company (the “Common Stock”) 

issued to the former Nellix stockholders at the closing of the Merger, if the Company receives approval from the FDA to sell the 
Nellix Product in the United States (the “PMA Milestone”), the Company will issue additional shares of the Common Stock to 
the former stockholders of Nellix. The dollar value of the shares of the Common Stock to be issued upon achievement of the 
PMA Milestone will be equal to $15.0 million (less the dollar value of certain cash payments and other deductions). The price 
per share of the shares of the Common Stock to be issued upon achievement of the PMA Milestone is subject to a stock price 
floor of $4.50 per share, but not subject to a stock price ceiling.

At December 31, 2017, the Company's stock price closed at $5.35 per share. Thus, had the PMA Milestone been achieved 
on December 31, 2017, the Contingent Payment would have comprised 2.9 million shares (based on the 30-day average closing 
stock price ending 5 days prior to the announcement, subjected to the stock price floor of $4.50), representing a value of $15.2 
million.

The value of the Contingent Payment is derived using a discounted income approach model, with a range of probabilities 
and assumptions related to the timing and likelihood of achievement of the PMA Milestone (which include Level 3 inputs - see 
Note 3(e) and the Company's stock price (Level 1 input) as of the balance sheet date). These varying probabilities and 
assumptions and changes in the Company's stock price have required fair value adjustments of the Contingent Payment in 
periods subsequent to the Nellix Closing Date.

The Contingent Payment fair value will continue to be evaluated on a quarterly basis until milestone achievement occurs, 
or until the expiration of the "earn-out period," as defined within the Nellix purchase agreement. Adjustments to the fair value 
of the Contingent Payment are recognized within other income (expense) in the Consolidated Statements of Operations and 
Comprehensive Loss.

The Company has evaluated the available evidence supporting the realization of its gross deferred tax assets, including the 

amount and timing of future taxable income, and has determined that it is more likely than not that the domestic and foreign 

77

ENDOLOGIX, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(all tabular amounts presented in thousands, except per share, per unit, and number of years)

deferred tax assets will not be realized. Due to such uncertainties surrounding the realization of the domestic and foreign 
deferred tax assets, the Company maintains a valuation allowance of $118.6 million against a substantial portion of its deferred 
tax assets as of December 31, 2017. For the year ended December 31, 2017, the total change in valuation allowance was $(15.2) 
million, of which $(25.0) million was recorded as a tax benefit through the income statement and  $9.8 million was recorded to 
equity mainly in connection with the Company's adoption of ASU 2016-09. Realization of the deferred tax assets will be 
primarily dependent upon the Company's ability to generate sufficient taxable income prior to the expiration of its net operating 
losses.

At December 31, 2017, the Company had net operating loss carryforwards for federal and state income tax purposes of 

approximately $314.0 million and $173.0 million, respectively.

Federal and state net operating loss carryforwards began expiring in 2017 and will continue to expire through 2037. The 

majority of the state net operating losses are attributable to California. In addition, the Company had research and development 
credits for federal and state income tax purposes of approximately $9.4 million and $14.3 million, respectively, which will 
begin to expire in 2020. The California research and development credits do not expire.

Under Section 382 of the Internal Revenue Code of 1986, as amended (“IRC”), substantial changes in our ownership may 

limit the amount of net operating loss and research and development income tax credit carryforwards that could be utilized 
annually in the future to offset taxable income. Specifically, this limitation may arise in the event of a cumulative change in 
ownership of our company of more than 50% within a three-year period. Any such annual limitation may significantly reduce  
the utilization of the net operating loss carryforwards before they expire.

Since the Company's formation, the Company has raised capital through the issuance of capital stock on several occasions 

which, combined with the purchasing stockholders' subsequent disposition of those shares, may have resulted in such an 
ownership change, or could result in an ownership change in the future upon subsequent disposition. The Company intends to 
complete a study in the future to assess whether an ownership change has occurred or whether there have been multiple 
ownership changes since the Company's formation.

The Company completed an analysis under IRC Sections 382 and 383 to determine if the acquired TriVascular 
Technologies, Inc.'s net operating loss carryforwards and research and development credits are limited due to a change in 
ownership. The Company concluded that TriVascular Technologies, Inc. had an ownership change as of February 3, 2016. As a 
result of the ownership change, the Company reduced the acquired federal and state net operating loss carryforwards by $230.3 
million and $209.4 million, respectively, and federal research and development credits by $3.1 million.

Our unrecognized gross tax benefits presented above would not reduce our annual effective tax rate if recognized because 

we have recorded a full valuation allowance on the deferred tax assets. We do not foresee any material changes to our gross 
unrecognized tax benefit within the next twelve months. We recognize interests and/or penalties related to income tax matters in 
income tax expense. We did not recognize any accrued interest and penalties related to gross unrecognized tax benefits related 
to the year ended December 31, 2017.  

The undistributed earnings of the Company's foreign subsidiaries are considered to be indefinitely reinvested. 
Accordingly, no provision for U.S. federal and state income taxes or foreign withholding taxes have been provided on such 
undistributed earnings. As of December 31, 2017, the cumulative amount of earnings upon which U.S. income taxes have not 
been provided is approximately $0.1 million. Determination of the potential amount of unrecognized deferred U.S. income tax 
liability and foreign withholding taxes is not practicable because of the complexities associated with its hypothetical 
calculation; however, net operating losses and unrecognized foreign tax credits would be available to reduce some portion of 
the U.S. liability.

In general, the Company is no longer subject to United States federal, state, local, or foreign examinations by taxing 
authorities for years before 2013, however, net operating loss and other tax attribute carryforwards utilized in subsequent years 
continue to be subject to examination by the tax authorities until the year to which the net operating loss and/or other tax 
attributes are carried forward is no longer subject to examination.

For the twelve months ended December 31, 2017, our provision for income taxes was $0.5 million benefit and our 
effective tax rate was (0.69%) for the year ended December 31, 2017. During the twelve months ended December 31, 2017, we 
had operating legal entities in the United States, Italy, New Zealand, Singapore, Poland, Germany, Switzerland, Korea and the 
Netherlands (plus registered sales branches of our Dutch entity in certain countries in Europe).

On December 22, 2017, the President of the United States signed into law the Tax Reform Act. The legislation 

significantly changes U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax 
system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. The Tax Reform Act 
permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018.

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred 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 tax basis. Deferred tax assets and liabilities are measured using 
enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. 
As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the Tax Reform Act, the Company 
revalued its ending net deferred tax liabilities at December 31, 2017 and recognized a $0.4 million tax benefit in the Company’s 
consolidated statement of income for the year ended December 31, 2017.

The Tax Reform Act provided for a one-time deemed mandatory repatriation of post-1986 undistributed foreign 

subsidiary earnings and profits (“E&P”) through the year ended December 31, 2017. The Company does not have undistributed 
foreign E&P subject to the deemed mandatory repatriation and therefore has not recognized income tax expense in the 
Company’s consolidated statement of operations and comprehensive loss for the year ended December 31, 2017.

While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base 

erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax 
(“BEAT”) provisions.

The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess 
of an allowable return on the foreign subsidiary’s tangible assets beginning in 2018. The Company does not believe that it will 
be subject to excess tax at this time under this new provision. In the event the Company becomes subject to this provision, it 
will elect to either account for the additional tax in the period in which it is incurred or to account for it through deferred taxes. 
On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. 
GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including 
computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The 
Company has recognized the provisional tax impacts related to deemed repatriated earnings and the revaluation of deferred tax 
assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. 
The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional 
analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, 
and actions the Company may take as a result of the Tax Reform Act. The accounting is expected to be complete when the 2017 
U.S. corporate income tax return is filed in 2018.

In the years ended December 31, 2017 and 2016, the Company recorded $1.5 million and $11.1 million, respectively in 

restructuring costs within operating expenses related to focused reductions of its workforce. The Company began substantially 
formulating plans around this workforce reduction during the first quarter of 2016 in conjunction with its merger of 
TriVascular. The targeted reductions and other restructuring activities were initiated to provide efficiencies and realign 
resources as well as to allow for continued investment in strategic areas and to drive growth. 

The Company expects to incur a total of $12.6 million in restructuring charges upon the completion of the plan, which 

represents the Company’s best estimate as of December 31, 2017. 

The recognition of restructuring charges requires that the Company make certain judgments and estimates regarding the 
nature, timing and amount of costs associated with the planned reductions of workforce. At the end of each reporting period, 
the Company will evaluate the remaining accrued balance to ensure that no excess accruals are retained and the utilization of 
the provisions are for their intended purpose in accordance with developed plans. The following table reflects the movement of 
activity of the restructuring reserve for the year ended December 31, 2017:

13. TriVascular Merger 

On February 3, 2016, the Company completed its merger with TriVascular pursuant to the Agreement and Plan of Merger 

(the “Merger Agreement”), dated October 26, 2015, by and among Endologix, TriVascular and Teton Merger Sub, Inc., a 
Delaware corporation and direct wholly-owned subsidiary of Endologix (“Merger Sub”). Pursuant to the terms of the Merger 
Agreement, Endologix acquired all of TriVascular’s outstanding capital stock through the merger of Merger Sub with and into 
TriVascular (the “Merger”), with TriVascular surviving the Merger as a wholly-owned subsidiary of Endologix. The Company 
completed the merger in order to become the innovation leader with broad clinical indications for the treatment of AAA, 
leverage the combined company’s commercial capabilities, and provide an accelerated path to profitability. The total purchase

consideration given related to the acquisition follows:

Common stock consideration consisted of 13,586,503 shares of Endologix common stock, worth $100.8 million based on 

the market value of $7.42 per share as of the effective date of the Merger on February 3, 2016.

 In connection with the Merger, the Company assumed stock warrants, originally issued by TriVascular, and converted 
them to Endologix stock warrants. The fair value of the stock warrants represents a component of the total consideration for the 
Merger.  Stock warrants assumed were valued using the Black-Scholes option pricing model as of the effective date of the 
Merger.

The acquisition was recorded by allocating the costs of the net assets acquired based on their estimated fair values at the 
acquisition date. The excess of the cost of the acquisition over the fair value of the net assets acquired is recorded as goodwill. 
The fair values were based on management’s analysis, including work performed by third-party valuation specialists. The 
following presents the allocation of the purchase consideration to the assets acquired and liabilities assumed on February 3, 
2016 (in thousands):

  Cash and cash equivalents
  Short-term investments
  Accounts receivable
  Inventories
  Prepaid expenses and other current assets
  Property and equipment
  Intangible assets

The goodwill is primarily attributable to strategic opportunities that arose from the acquisition of TriVascular, such as 
broadening the product portfolio for the treatment of AAA and leveraging the combined company’s technology and commercial 
capabilities. The goodwill is not expected to be deductible for tax purposes. 

During the year ended December 31, 2016, the Company revised the opening net assets acquired and goodwill by $27.1 
million, which was comprised of the following: an increase in inventories of $0.2 million; an increase in prepaid expenses and
other current assets of $0.1 million; an increase in accounts receivable of $0.2 million; and an increase in accrued liabilities
and other of $0.6 million as a result of gathering additional information during the measurement period. The Company also
revised the initial values of intangible assets by decreasing them $27.0 million as a result of switching from utilizing
publicly available benchmarking information to determine the fair value of the intangible assets to primarily utilizing an income
method based on forecasts of expected future cash flows. During the three months ended June 30, 2016, the Company recorded
an adjustment to the amortization of intangible assets of $0.3 million, comprising of a $0.2 million and $49 thousand decrease 
within cost of goods sold and marketing and sales expense, respectively, in the Consolidated Statement of Operations and 
Comprehensive Loss, that would have been recorded during the three months ended March 31, 2016, if the adjustment to the 
intangible assets had been recognized as of the date of the Merger.

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

Trade payables, as well as other current and non-current assets and liabilities, were valued at the existing carrying values 
as they represented the fair value of those items at the acquisition date, based on management’s judgments and estimates. Trade 
receivables included gross contractual amounts of $5.8 million and the Company's best estimate of a nominal amount of 
contractual cash flows not expected to be collected at the acquisition date.

The fair value of property, plant and equipment utilized a combination of the cost and market approaches, depending on 

the characteristics of the asset classification. Of the $46.2 million of acquired intangible assets, $7.5 million was assigned to 
customer relationships (10 year life), $27.5 million was assigned to developed technology (11 year life), and $11.2 million was 
assigned to in-process research and development.

Pro Forma Combined Financial Information (Unaudited)

The following unaudited pro forma financial information summarizes the results of operations for the periods indicated as if the 
TriVascular merger had been completed as of January 1, 2015. Pro forma information reflects adjustments that are expected to 
have a continuing impact on our results of operations and are directly attributable to the merger. The unaudited pro forma 
results include adjustments to reflect the amortization of the inventory step-up, direct transaction costs relating to the 
acquisition, the incremental intangible asset amortization to be incurred based on the values of each identifiable intangible 
asset, and to eliminate interest expense related to legacy TriVascular's former loans, which was repaid upon completion of the 
TriVascular merger. The pro forma amounts do not purport to be indicative of the results that would have actually been obtained 
if the merger had occurred as of January 1, 2015 or that may be obtained in the future, and do not reflect future synergies, 
integration costs, or other such costs or savings.

CONTROLS AND PROCEDURES.

Management’s Annual Report on Internal Control over Financial Reporting

Our management, including our chief executive officer and chief financial officer, is responsible for establishing and 
maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange 
Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability 
of the financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. This process includes those policies and procedures that (i) pertain to the maintenance of 
records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide 
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with 
authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection 
of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

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

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. In 

making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the 
Treadway Commission in the report entitled Internal Control-Integrated Framework (2013). Based on its assessment, our 
management has concluded that, as of December 31, 2017, our internal control over financial reporting was effective based on 
those criteria.

KPMG LLP, an independent registered public accounting firm, has audited the effectiveness of our internal control over 

financial reporting as of December 31, 2017 as stated in its report, which is included herein.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act. Our 
disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that we 
file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the 
SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief 
executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In 
designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no 
matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and 
management was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision of and with the participation of our management, including our chief 
executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures as of December 31, 
2017, pursuant to Rule 13a-15(b) under the Exchange Act.  Based on that evaluation, our chief executive officer and chief 
financial officer have concluded that our disclosure controls and procedures were effective as of December 31, 2017.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) 
under the Exchange Act) during the fourth quarter of the fiscal year ended December 31, 2017 that has materially affected, or is 
reasonably likely to materially affect, our internal control over financial reporting.
