Item 1. Business

Overview

LeMaitre Vascular is a global provider of medical devices and implants for the treatment of peripheral vascular disease. We develop, manufacture, and market vascular devices to address the needs of vascular surgeons. Our diversified portfolio of peripheral vascular devices consists of brand name products that are used in arteries and veins outside of the heart and are well known to vascular surgeons, including the Expandable LeMaitre Valvulotome, the Pruitt F3 Carotid Shunt, VascuTape Radiopaque Tape and the XenoSure biologic patch.

We have grown our business by using a three-pronged strategy: competing in niche markets, expanding our worldwide direct sales force, and acquiring and developing complementary vascular devices. Since 1998 we have built our sales force from zero to 85 direct sales representatives as of December 31, 2013 and we have completed a number of vascular device acquisitions.

1

We estimate that peripheral vascular disease affects more than 20 million people worldwide. We estimate that the annual worldwide market for all peripheral vascular devices is approximately $3 to $4 billion and that the annual worldwide market addressed by our core product lines approximates $800 million. We believe that this market will grow due to the increase in the incidence and diagnosis of peripheral vascular disease, a shift to higher priced endovascular devices, and the adoption of western healthcare standards by the developing world. We believe that our strong brands, established sales force, evolving suite of peripheral vascular devices, and broad network of vascular surgeon customers position us to capture an increasing share of this large and growing market.

We sell 14 product lines, most of which are used in open vascular surgery and some of which are used in endovascular procedures. For 2013, 2012 and 2011, our valvulotomes, balloon catheters, and carotid shunt product lines have each comprised more than 10% of our revenues. Additionally, our radiopaque tape comprised 8% of our revenues in 2013 compared to 10% and 9% of our revenues in 2012 and 2011, respectively. Finally, our XenoSure biologic patches comprised 12% of our revenues in 2013 compared to 9% and 5% in 2012 and 2011, respectively. In none of those years, including 2013, did any single product line account for more than 25% of our revenues.

Historically, we have been a leading provider of vascular surgery products in niche product markets characterized by low or limited competition. More recently we have sought to leverage our market leadership in these niche product markets by selling complementary products in more competitive, larger market segments. In addition, our vascular surgeon customers are increasingly performing minimally invasive endovascular procedures, presenting us with attractive opportunities to sell new devices that address their changing product needs.

We sell our products primarily through a direct sales force. Our sales force was comprised of 85 field sales representatives in North America, Europe and Japan as of December 31, 2013. We also sell our products through distributors in countries where we do not have a direct sales force. For the year ended December 31, 2013, approximately 92% of our net sales were generated through our direct sales force, and no single customer accounted for more than 1% of our net sales.

The Peripheral Vascular Device Market

We estimate that peripheral vascular disease affects more than 20 million people worldwide. The disease encompasses a number of conditions in which the arteries or veins that carry blood to or from the legs, arms, or organs other than the heart become narrowed, obstructed, weakened, or otherwise compromised. In many cases peripheral vascular disease goes undetected, sometimes leading to life-threatening events—such as stroke, ruptured aneurysm, or pulmonary embolism—or death.

Clinical studies have identified several factors that increase the risk of peripheral vascular disease, including smoking, diabetes, obesity, high blood pressure, lack of exercise, coronary artery disease, high cholesterol, and being over the age of 65. Demographic trends suggest an increase in the prevalence of peripheral vascular disease over time, driven primarily by rising levels of obesity and diabetes and an aging population.

Vascular surgeons treat peripheral vascular disease and also perform vascular procedures associated with other diseases, such as end-stage renal disease. We estimate that there are more than 2,000 board-certified vascular surgeons and several thousand general surgeons who perform vascular procedures in the United States, and that there are more than 3,000 vascular surgeons in Europe, Asia and the Pacific Rim. In contrast to other medical specialists, such as interventional cardiologists and interventional radiologists, vascular surgeons perform both conventional vascular surgeries and endovascular procedures. Conventional vascular surgery involves opening the body, cutting vessels, and suturing. Endovascular procedures typically are minimally invasive, catheter-based procedures involving repairing vessels from within using real-time imaging technologies.

Our History

We were founded in 1983 by George D. LeMaitre, M.D., a vascular surgeon who designed and developed the predecessor to our Expandable LeMaitre Valvulotomes and Over-The-Wire LeMaitre Valvulotome. Through a combination of strategic acquisitions and research and development efforts, we have expanded to 14 product lines.

We have completed fourteen acquisitions of complementary products since 1998:

Year	Acquisition	Key Product(s)
1998	Whittaker Screen Printing	Radiopaque tape manufacturing operations
1999	Vermed	Balloon catheters
2001	Ideas for Medicine	Carotid shunts, balloon catheters, and laparoscopic cholecystectomy devices
2003	Credent	Vascular access grafts
2004	VCS Clip	Vessel closure system
2005	Endomed	Thoracic and abdominal stent grafts
2007	Vascular Innovations	Contrast injector
2007	Vascular Architects	Remote endarterectomy devices
2007	UnBalloon Technology	Stent graft modeling catheters
2007	Biomateriali	Polyester grafts and patches
2010	LifeSpan	ePTFE grafts
2012	XenoSure	Biologic vascular patch
2013	Clinical Instruments	Carotid Shunts and Embolectomy Catheters
2013	TRIVEX	Powered phlebectomy system

With the exception of the recently acquired TRIVEX product lines, we have relocated most of the manufacturing operations associated with these acquisitions to our Burlington, Massachusetts, headquarters and we continue to look at ways to make our operations more efficient.

Our Business Strategies

Our goal is to be a leading global provider of medical devices to vascular surgeons.

To achieve this objective, we are utilizing the following long-term strategies:

• Focus on niche markets. We seek to build and maintain market-leading positions in niche product markets. We believe that the relative lack of competitive focus on these markets by larger competitors with greater resources, and the differentiated features and consistent quality of our products, allow for higher selling prices in these markets. In recent years we have sought to leverage these market-leading share positions by selling complementary products in more competitive, larger market segments.

• Expand our direct sales force. We sell our products primarily through a direct sales force in North America, Europe and Japan. We intend to further expand our sales force over time. We believe that direct-to-hospital sales build closer customer relationships, allow for higher selling prices, and are not subject to the risk of customer churn related to distributor turnover.

• Add complementary products through acquisitions, research and development, and additional regulatory approvals. We intend to further expand and diversify our product offerings and add new technology platforms. We believe our significant experience in acquiring and integrating product lines and businesses is one of our competitive advantages. We actively track industry developments and evaluate the acquisition of additional product lines and businesses that may be complementary to our product offerings, refine our current product lines, develop new applications for our existing technologies, and obtain regulatory approvals for our devices in new markets in order to further access the broader peripheral vascular device market.

(1) Due to varying regulatory schemes and product introduction timelines, it may be that only some models within the applicable product line are approved for sale in the indicated market. For example, in our carotid shunts product line, our Pruitt-Inahara carotid shunts are available for sale in the United States, the European Union and Japan, but our Pruitt F3 carotid shunts are not available for sale in Japan (though we have submitted an application for regulatory approval for this product in Japan).

Balloon Catheters for Embolectomy, Occlusion and Perfusion

Our LeMaitre line of embolectomy catheters are used to remove blood clots from arteries or veins. We manufacture single-lumen latex and latex-free embolectomy catheters as well as dual-lumen latex embolectomy catheters. The dual-lumen embolectomy catheter allows clot removal and simultaneous irrigation or guide-wire tractability. Occlusion catheters temporarily occlude blood flow to allow the vascular surgeon time and space to complete a given procedure. Perfusion catheters temporarily perfuse blood and other liquids into the vasculature. Our Pruitt line of occlusion and perfusion catheters reduces vessel trauma by using internal balloon fixation rather than traditional external clamp fixation.

Carotid Shunts

Our Pruitt F3, Pruitt-Inahara, Inahara-Pruitt, Flexcel and latex-free Carotid Shunts are used to temporarily divert, or shunt, blood to the brain while the surgeon removes plaque from the carotid artery in a carotid endarterectomy surgery. Our Pruitt F3, Pruitt-Inahara, and Inahara-Pruitt shunts feature internal balloon fixation that eliminates the need for clamps, thereby reducing vessel trauma. Our Flexcel shunt is a non-balloon shunt offered for surgeons who prefer to secure their shunt using externally placed clamps.

Modeling Catheters

Our UnBalloon Non-Occlusive Modeling Catheter is used to apply radial pressure to the inside of an aortic stent graft in order to seal the outer lining of the stent graft against either the aorta or an adjacent stent graft. Unlike a traditional balloon catheter, The UnBalloon dilates the aortic stent graft without occluding blood flow, allowing the physician more time to repair an endoleak or model the stent graft while minimizing the risk of stent graft migration during modeling.

Radiopaque Tape

Our VascuTape Radiopaque Tape is a flexible, medical-grade tape with centimeter or millimeter markings printed with our proprietary radiopaque ink that is visible both to the eye and to an x-ray machine or fluoroscope. VascuTape Radiopaque Tape is applied externally to the skin and provides interventionalists with a simple way to cross-reference between the inside and the outside of a patient’s body, allowing them to locate tributaries or lesions beneath the skin.

Remote Endarterectomy Devices

Our EndoRE line of remote endarterectomy devices are used to remove severe atherosclerotic blockages from the major arteries of the leg in a minimally invasive procedure requiring a single incision in the groin. Our EndoRE devices are used to separate the sclerotic blockage from the vessel, cut the far end of the blockage to free it for removal, and then withdraw the blockage from the vessel.

Valvulotomes

Our Expandable LeMaitre Valvulotomes and our Over-The-Wire LeMaitre Valvulotomes cut valves in the saphenous vein, a vein that runs from the foot to the groin, so that the vein can function as a bypass vessel to carry blood past diseased arteries to the lower leg or the foot. We believe that our valvulotomes reduce costs for hospitals by enabling less invasive bypass surgery to be performed with several small incisions rather than one

5

continuous ankle-to-groin incision, thereby reducing the length of hospital stays and the likelihood of wound complications. The 1.5mm Expandable LeMaitre Valvulotome is the seventh generation of the original valvulotome developed by our founder, George D. LeMaitre, M.D.

Vascular Grafts

Our AlboGraft Woven and Knitted Vascular Grafts are collagen-impregnated polyester grafts used to bypass or replace diseased arteries. They are available in both straight tube and bifurcated versions.

Our LifeSpan ePTFE Vascular Graft is an expanded polytetrafluoroethylene (ePTFE) graft used to bypass or replace diseased arteries, and to create dialysis access sites. They are available in both regular and thin wall options and with an optional full or partial external spiral support to increase resistance to compression or kinking. Our stepped and quick tapered LifeSpan models are designed to reduce the risk of steal syndrome and high cardiac output, which are complications that may arise in dialysis access grafts.

Vascular Patches

We sell the XenoSure Biologic Vascular Patch, a patch made from bovine pericardium. In 2008, we obtained exclusive rights to distribute this product under our “XenoSure” brand in the United States, and in 2012, we exercised our option to acquire this product. Our AlboSure Vascular Patch is a polyester patch. Vascular surgeons use patches in conjunction with carotid endarterectomy, remote endarterectomy, and other vascular reconstructions.

Powered Phlebectomy Devices

Our TRIVEX powered phlebectomy system is comprised of capital equipment and disposables that enable less invasive removal of varicose veins. In this procedure, an illuminator is inserted through a small incision into the leg, enabling visualization of varicose veins. A second instrument removes the veins. Compared to conventional hook phlebectomy, this surgical procedure is faster and results in more complete vein removal through fewer incisions.

Vessel Closure Systems

Our AnastoClip and AnastoClip GC Vessel Closure Systems allow surgeons to attach vessels to one another by deploying titanium clips in place of suturing. These vessel closure systems create an interrupted anastomosis, or a vessel attachment that expands and contracts as the vessel pulses, which we believe improves the durability of the anastomosis.

Other Products

In some hospitals, vascular surgery procedures are performed by general surgeons. We also sell non-vascular medical devices used in general surgery procedures, primarily laparoscopic cholecystectomy. Our leading general surgery product is the Reddick Cholangiogram Catheter, which is used to inject dye into the cystic duct during laparoscopic cholecystectomy. In this procedure, the gall bladder is dissected and removed through small punctures in the abdomen. We also offer two laparoscopic accessories used in laparoscopic gall bladder removal.

Sales and Marketing

As of December 31, 2013, we employed 85 field sales representatives. Notable developments in late 2013 include our initiative to sell direct-to-hospital in Norway and to set up an office in Melbourne, Australia. We believe that the expansion of our direct sales force has been a key factor in our success and it remains one of our primary long-term strategies.

Outside our direct markets, we generally sell our products through country-specific distributors. We typically sign exclusive distribution agreements with terms of up to three years frequently specifying minimum

6

annual sales volumes and pricing. These agreements are renewable by mutual agreement. From time to time, when we determine that it would be financially advantageous for us to sell directly in a market, we terminate one or more of our distributors in that market. In December 2012, we agreed to terminate our distributor for a certain Japanese territory, and we began selling direct-to-hospital in this territory through our existing eight person Japanese sales force in 2013. In October 2013, we agreed to terminate our distributors in Australia and Norway, and we began selling direct-to-hospital in those territories in January 2014.

In addition, we engage in direct marketing efforts, including direct mail and exhibitions at medical congresses, which we believe are important to our brand development and continued success. We believe that direct marketing allows us to market to vascular surgeons beyond the reach of our direct sales force.

Research and Development

Our research and development has historically focused on developing enhancements and extensions to our existing product lines. Our current product development efforts are primarily focused on the open vascular space and are largely improvements to our existing devices. In recent years we have increased investment in product research and development, with the goal of more rapidly developing new products, line extensions, and next-generation devices. In 2013 our development efforts were focused on launching the MultiTASC device, a two-in-one tool for dissecting, cutting and removing total occlusions of the superficial femoral artery, the 1.5mm Expandable LeMaitre Valvulotome, a smaller-size of our classic Expandable LeMaitre Valvulotome, and the AlboSure vascular patch, a polyester alternative to our XenoSure biologic vascular patch.

Our products are subject to our design control procedures throughout the various stages of product development. These procedures may include bench testing, animal testing, human procedures conducted by independent physicians, and post-market surveillance of product performance, as appropriate. We may use feedback received from independent physicians to demonstrate product functionality before commencing full-scale marketing of any product.

For 2013, 2012, and 2011, our research and development expenditures were $5.2 million, $5.1 million and $4.4 million, respectively, representing between 8% and 9% of net sales. As of December 31, 2013, our research and development staff consisted of 16 full-time engineers and technicians.

Manufacturing

Our manufacturing facilities are located in Burlington, Massachusetts, where most of our product lines are produced in three clean rooms. In 2013, we completed the build-out of our third clean room in Burlington for the production of the XenoSure biologic vascular patch. Our most recent manufacturing consolidation into Burlington, Massachusetts was the launch of production of the XenoSure biologic vascular patch in 2013. While we ramp production of the XenoSure biologic vascular patch in our facility, we continue to source product from Neovasc Inc. We expect this transition to our Burlington facility to be complete in the second half of 2014. In January 2014, we also initiated a project to transfer the manufacturing of the newly acquired Clinical Instruments devices to our facility in Burlington. We expect the transfer to be complete in the second quarter of 2014. Although almost all of our product lines are produced in Burlington, Massachusetts, our TRIVEX and EndoRE products are currently manufactured by third-parties.

We manufacture certain proprietary components, assemble most of our devices ourselves, and inspect, test, and package all of our finished products. By designing and manufacturing many of our products from raw materials, and assembling and testing as many of our subassemblies and products as practical, we believe that we can maintain better quality control, ensure compliance with applicable regulatory standards and our internal specifications, limit outside access to our proprietary technology, ensure adequate product supply, and make design modifications in a timely manner. We have custom-designed proprietary manufacturing and processing equipment and have developed proprietary enhancements for existing production machinery. Our products are built to stock.

7

Our management information systems provide us with the ability to evaluate our performance, collect business intelligence, and make better strategic decisions. These systems include order entry, invoicing, on-line inventory management, lot traceability, purchasing, shop floor control, and shipping and distribution analysis, as well as various accounting-oriented functions. During day-to-day operations, these systems enable us to track our products from the inception of an order through the manufacturing process and then through delivery of the product to the customer.

We purchase components from, and have certain product lines manufactured by, third parties. Most of our components are readily available from several supply sources, but we do rely on single- and limited-source suppliers for several of our key product components and our third-party-manufactured products. We do not have contractual arrangements with most of these suppliers and manufacturers, and we order our supplies and product on an as-needed basis. To date, we have not experienced any material disruption in the adequate supply from existing sources of product and components, but there is no guarantee that we will not experience such disruptions in the future.

Any disruption in our manufacturing capacity could impact our ability to produce sufficient inventory and meet the demands of our customers, which could adversely affect our financial condition and results of operations.

Our Burlington manufacturing facilities have been certified to ISO 13485:2003 quality management system standards, which enables us to satisfy certain regulatory requirements of the European Union, Canada, and other foreign jurisdictions. If we were to lose these certifications, we would no longer be able to sell our products in these countries until we made the necessary corrections to our operations. Our manufacturing facilities are subject to periodic inspections by regulatory authorities and our Notified Bodies (described below) to ensure compliance with domestic and non-U.S. regulatory requirements. See “—Government Regulation.” In February 2013, we underwent an audit by the FDA and in November and December 2013, we underwent European Notified Body audits. Although the results of these inspections were satisfactory, the timing and scope of future audits is unknown and it is possible, despite our belief that our quality systems and the operation of our manufacturing facilities will remain in compliance with U.S, and non-U.S. regulatory requirements, that a future audit may result in one or more unsatisfactory results.

Competition

The markets in which our product lines compete are characterized by rapid change resulting from technological advances and scientific discoveries. No one company competes against all of our product lines. Rather, we compete with a range of companies, from large to small, including publicly traded and privately held device companies. Notable competitors include Applied Medical Resources Corporation, Baxter International, Inc., Cardiovascular Systems, Inc., C.R. Bard, Inc., Edwards Lifesciences Corporation, Getinge AB, Jotec GmbH, SAS Perouse Medical, Terumo Medical Corporation, Uresil, LLC, and W. L. Gore & Associates.

Our products compete primarily on the basis of their innovative technology, quality, reliability, ease of use, cost-effectiveness, physician familiarity, brand recognition, and service support. While we compete, where appropriate, on the basis of price, several of our products are sold at higher prices than those of our competitors. We believe that our continued success will depend on our ability to broaden and optimize our direct sales channel, acquire or develop additional vascular device product lines, obtain patent or other product protections, obtain regulatory and reimbursement approvals, maintain sufficient inventory to meet customer demand, and attract and retain skilled personnel.

Many of our competitors have substantially greater financial, technological, research and development, regulatory, marketing, sales, and personnel resources than we do. Certain of these competitors are able to manufacture at lower costs and may therefore offer comparable products at lower prices. Certain of these competitors may also have greater experience in developing and further improving products, obtaining regulatory approvals, and manufacturing and marketing such products. Certain of these competitors may obtain patent protection or regulatory approval or clearance, or achieve product commercialization, before us, any of which could materially adversely affect us.

8

Intellectual Property

We believe that our success is dependent, to a certain extent, on the development and maintenance of proprietary aspects of our technologies. We rely on a combination of patents, trademarks, trade secret laws, and confidentiality and invention assignment agreements to protect our intellectual property rights.

We actively maintain and pursue patents in the United States, Europe and other strategic locations relating to various aspects of our products and/or manufacturing processes. The majority of our issued U.S. patents are set to expire at various times from 2015 to 2032.

Generally, for products that we believe are appropriate for patent protection, we will attempt to obtain patents in the United States and key markets of the European Union. However, depending on circumstances, we may not apply for patents in all or any of those jurisdictions, or we may pursue patent protection elsewhere.

Notwithstanding the foregoing, the patent positions of medical device companies, including our company, are uncertain and involve complex and evolving legal and factual questions. The coverage sought in a patent application can be denied or significantly reduced either before or after the patent is issued. Consequently, there can be no assurance that any of our pending patent applications will result in an issued patent. There is also no assurance that any existing or future patent will provide significant protection or commercial advantage, or whether any existing or future patent will be dominated by a more basic patent, thus possibly requiring us to obtain a license to produce and sell the product.

Third parties may claim that our products infringe on their patents and other intellectual property rights. Some companies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents, licenses, or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigation costs, be forced to make expensive changes to our product designs, license rights in order to continue manufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divert our management’s time and effort. Such claims could also cause our customers or potential customers to defer or limit their purchase or use of the affected products until resolution of the claim. See “Risk Factors” for a description of risks associated with our intellectual property.

Certain aspects of our products are covered by patents held by third parties. We manufacture, market, and sell these products pursuant to license agreements with these third parties. These arrangements require us to pay royalties, typically determined as a percentage of our net sales for the underlying product. If we fail to make these payments or otherwise fail to observe the terms of these agreements, we may lose our ability to sell these products. For example, we manufacture, market, and sell our LifeSpan Vascular Grafts, MollRing Cutter and MultiTASC devices, Reddick-Saye Screws, Periscope Dissectors and TRIVEX productspursuant to licenses with third-parties.

We believe that our strong brands have been an important factor in our success. We rely on common law and registered trademarks to protect our product brands. Some of our registered trademarks are LeMaitre, XenoSure, Pruitt, VascuTape, Glow ‘N Tell, and Reddick, each of which is registered in the United States and the European Union, and in certain cases in other foreign countries.

We rely on trade secret protection for certain unpatented aspects of other proprietary technology. Some of our products are not protected by patents. In the past, other companies have independently developed or otherwise acquired comparable or substantially equivalent proprietary information and techniques, and there can be no assurance that others will not do so in the future or otherwise gain access to our proprietary technology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees and consultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentiality agreements also require our employees to assign to us all

9

rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer, or disclosure of confidential information or inventions.

The laws of foreign countries generally do not protect our proprietary rights to the same extent as do the laws of the United States and we may experience more difficulty enforcing our proprietary rights in certain foreign jurisdictions.

Government Regulation

The products we manufacture and market are subject to regulation by the FDA, and, in some instances, other federal and state authorities and foreign governments.

United States Regulation

Our products are medical devices subject to extensive regulation by the FDA under the Federal Food, Drug, and Cosmetic Act (the FDCA). FDA regulations govern, among other things, product development, testing, manufacturing, packaging, labeling, storage, clearance or approval, advertising and promotion, sales and distribution, and import and export.

Premarket Pathways

Most medical devices must receive either 510(k) clearance or premarket application approval (PMA approval) from the FDA prior to commercial distribution. Devices deemed to pose relatively less risk are placed in either class I or II, which requires the manufacturer to submit a premarket notification requesting permission for commercial distribution; this is known as 510(k) clearance. Some low-risk devices are exempted from this requirement. Class II devices may be subject to special controls, such as performance standards and FDA guidelines that are not applied to class I devices. Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting, or implantable devices, or devices deemed not substantially equivalent to a previously 510(k)-cleared device or to a pre-amendment class III device (i.e., one in commercial distribution before May 28, 1976) for which PMA applications have not been called, are placed in class III, which generally requires PMA approval. In all cases, a user fee is required for 510(k) submissions and PMA applications, which in the case of PMA applications can be very costly.

510(k) Clearance. To obtain 510(k) clearance, a manufacturer must submit a premarket notification demonstrating that the proposed device is substantially equivalent in intended use and performance to a “predicate device” (i.e., a previously 510(k)-cleared class I or class II device or a pre-amendment class III device for which the FDA has not yet called for PMA applications). The FDA’s 510(k) clearance pathway usually takes from three to twelve months, but it can last longer. In reviewing a premarket notification, the FDA may request additional information, including clinical data. Nearly all of our devices sold in the United States to date are marketed pursuant to the 510(k) process.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change as specified by FDA guidelines, requires a new 510(k) clearance. The FDA requires each manufacturer to make this determination in the first instance, but the FDA can review any such decision. If the FDA disagrees with a manufacturer’s decision not to seek a new 510(k) clearance, the agency may retroactively require the manufacturer to seek 510(k) clearance. The FDA also can require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or PMA approval is obtained. Also, the manufacturer may be subject to significant regulatory fines or penalties.

PMA Approval. The PMA approval pathway requires proof of the safety and effectiveness of the proposed device to the FDA’s satisfaction, making this pathway much more costly, lengthy, and uncertain. A PMA

10

application must provide extensive preclinical and clinical trial data, as well as detailed information about the device and its components regarding, among other things, device design, manufacturing, and labeling. As part of the PMA review, the FDA will typically inspect the manufacturer’s facilities for compliance with the Quality System Regulation (QSR) which imposes elaborate testing, control, documentation, and other quality assurance procedures on the manufacturing process.

If the FDA approves a PMA, the approved indications or claims may be more limited than those originally sought. The PMA can include post-approval conditions that the FDA believes to be necessary to ensure the safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale, and distribution. Failure to comply with the conditions of approval can result in material adverse enforcement action, including the loss or withdrawal of the approval. Even after approval of a PMA, a new PMA or PMA supplement is required if the device or its labeling or manufacturing process are modified. Supplements to a PMA often require the submission of the same type of information required for an original PMA, except that the supplement is generally limited to that information needed to support the proposed change from the product covered by the original PMA.

Clinical Trials. A clinical trial is typically required to support a PMA application and is sometimes required to support 510(k) clearance. In some cases, one or more smaller feasibility IDE studies may precede a pivotal IDE clinical trial intended to comprehensively demonstrate the safety and effectiveness of the investigational device. All clinical studies of investigational devices must be conducted in compliance with the FDA’s extensive requirements. If an investigational device could pose a significant risk to patients (as defined in the regulations), the FDA, prior to initiation of clinical use, must approve an IDE application showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. A non-significant risk device does not require submission to the FDA of an IDE application. Both significant risk and non-significant risk investigational devices require approval from institutional review boards (IRBs) at the study centers where the device will be used. The FDA and the IRB at each institution at which a clinical trial is being performed may suspend a clinical trial at any time for various reasons, including a belief that the subjects are being exposed to an unacceptable health risk.

During a study, the sponsor must comply with the FDA’s IDE requirements for investigator selection, trial monitoring, reporting, record keeping, and prohibitions on the promotion of investigational devices. The investigators must obtain patient informed consent, rigorously follow the investigational plan and study protocol, control the disposition of investigational devices, and comply with all reporting and record-keeping requirements. Required records and reports are subject to inspection by the FDA. Prior to granting PMA approval, the FDA typically inspects the records relating to the conduct of the study and the clinical data supporting the PMA application for compliance with IDE requirements.

Although the QSR does not fully apply to investigational devices, the requirement for controls on design and development does apply. The sponsor also must manufacture the investigational device in conformity with the quality controls described in the IDE application and any conditions of IDE approval that FDA may impose with respect to manufacturing.

Historically, our products have been introduced into the market using the 510(k) clearance procedure, and we have not used the more burdensome PMA process for any of the products that we currently market or sell in the United States.

Postmarket Regulation

After a device is placed on the market, regardless of the classification or premarket pathway, significant regulatory requirements apply. These include:

• manufacturing establishment registration and device listing with the FDA;

• the QSR, which requires finished device manufacturers, including third-party or contract manufacturers, to follow stringent design, testing, control, documentation, and other quality assurance procedures in all aspects of manufacturing;

11

• labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved, or off-label uses and other requirements related to promotional activities;

• medical device reporting regulations, which require that manufacturers report to the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur; and

• corrections and removal reporting regulations, which require that manufacturers report to the FDA any field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health.

We are subject to inspection and marketing surveillance by the FDA to determine our compliance with regulatory requirements. Our most recent FDA inspection was in February 2013, and was satisfactory. Non-compliance with applicable FDA requirements can result in, among other things, public warning letters, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grant marketing approvals, withdrawal of marketing approvals, a recommendation by the FDA to disallow us to enter into government contracts, and criminal prosecutions. The FDA also has the authority to request repair, replacement, or refund of the cost of any device manufactured or distributed by us. In the event that one of our suppliers fails to maintain compliance with our quality requirements, we may have to qualify a new supplier and could experience manufacturing delays as a result.

Non-U.S. sales of medical devices manufactured in the United States that are not approved or cleared by the FDA for use in the United States, or are banned or deviate from lawful performance standards, are subject to FDA export requirements. Before exporting such products to a foreign country, we must first comply with the FDA’s regulatory procedures for exporting unapproved devices.

Other U.S. Regulations

We, and our products, are also subject to a variety of state and local laws in those jurisdictions where our products are or will be marketed, and federal, state, and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potentially hazardous substances. We are subject to various federal and state laws governing our relationships with the physicians and others who purchase or make referrals for our products. For instance, federal law prohibits payments of any form that are intended to induce a referral for any item payable under Medicare, Medicaid, or any other federal healthcare program. Many states have similar laws. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a material adverse effect upon our ability to do business.

We are subject to federal, state, and local laws, rules, regulations, and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling, and disposal of certain hazardous and potentially hazardous substances used in connection with our operations. Although we believe that we have complied with these laws and regulations in all material respects and to date have not been required to take any action to correct any noncompliance, there can be no assurance that we will not be required to incur significant costs to comply with environmental regulations in the future.

Non-U.S. Regulation

Sales of medical devices are subject to regulatory requirements in many countries. The regulatory review process may vary greatly from country to country. For example, the European Union has adopted numerous directives and standards relating to medical devices regulating their design, manufacture, clinical trials, labeling, and adverse event reporting, including the Medical Devices Directive (93/42/EEC) (the Directive), which is applicable to our products. Devices that comply with the requirements of the Directive are entitled to bear a CE mark, indicating that the device conforms with the essential requirements of the applicable directive and can be

12

commercially distributed in countries that are members of the European Union, as well as Iceland, Lichtenstein, Norway, and Switzerland. Each member state of the European Union has implemented the directives into its respective national law and has each established a “Competent Authority” to apply the directive in its territory.

The Directive defines a classification system placing devices into Class I, IIa, IIb, or III, depending on the risks and characteristics of the medical device. The Directive also defines the essential requirements that devices must meet before being placed on the market, establishes assessment procedures for approving a device for marketing, and creates mechanisms for national authorities to manage implementation or to intervene when public health requires. Essential requirements include manufacturing, design, performance, labeling, and safety requirements, and may include providing certain clinical data. These requirements vary based on the type of the device and other related factors.

A manufacturer of low-risk devices typically may demonstrate conformity to the essential requirements based on a self-declaration. The European Standardization Committees have adopted numerous harmonized standards for specific types of medical devices. Compliance with relevant standards establishes a presumption of conformity with the essential requirements. Manufacturers of higher-risk devices generally must use a “Notified Body”—an appointed independent third party to assess conformity. This third-party assessment may consist of an audit of the manufacturer’s quality system and specific testing of the manufacturer’s devices. An assessment by a Notified Body in one country within the European Union is generally required in order for a manufacturer to commercially distribute the product throughout the European Union. Most of our devices are considered higher-risk devices that require Notified Body assessment.

The European medical device laws also address the advertising and promotion of medical devices, clinical investigations, and requirements for handling adverse events. Post-market surveillance of medical devices in the European Union is generally conducted on a country-by-country basis; however, the Directive sets forth certain specific requirements for reporting adverse events. The Medical Device Vigilance system is the mechanism by which adverse event reporting is managed and monitored in the European Union.

In the event that any of our products proves to be defective, we can voluntarily recall, or the FDA or foreign equivalent could require us to implement a recall of, any of our products and, if someone is harmed by a malfunction or a product defect, we may experience product liability claims for such defects. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital and may harm our reputation and financial results. Future recalls or claims could also result in significant costs to us and significant adverse publicity, which could harm our ability to market our products in the future.

In some cases, we rely on our non-U.S. distributors or third party agents to obtain premarket approvals, complete product registrations, comply with clinical trial requirements, and complete those steps that are customarily taken in the applicable jurisdictions to comply with governmental and quasi-governmental regulation. In the future, we expect to continue to rely on distributors and agents in this manner where appropriate.

In Japan, the Ministry of Health, Labor and Welfare (MHLW) regulates medical devices through the Pharmaceutical Affairs Law, which was reformed effective April 1, 2005. The revisions to Japan’s regulations have resulted in longer lead times for product registration.

Canada regulates the import and sale of medical devices through Health Canada (HC). HC classifies medical devices into four classifications, with Class I being the lowest risk and Class IV being the highest. Class I and II devices are often cleared for sale after they are CE marked or listed on the company’s ISO certification and filed via fax-back applications, which are typically processed relatively quickly. Higher classification risk devices (Class III and IV) require filing of dossiers that resemble US 510(k) applications. These applications can range in cost and typically take longer for approval.

13

Australia regulates the import and sale of medical devices through the Therapeutic Goods Administration (TGA). The TGA has built its regulatory framework around similar requirements to those issued in Europe. As such, many medical devices (those with a lower risk profile) may gain relatively fast marketing clearance using their existing EU issued CE marking. Higher risk devices (those in EU/Aus Class III) must go through a full design review which can be costly and take longer to complete. Issued licenses for medical devices do not require renewal, but do require an annual fee to remain active in the TGA registry of devices. Australia requires all foreign manufacturers to have an in country ‘sponsor’ who must have a licensed business inside of Australia.

In China, The China Food and Drug Administration (CFDA) Medical Device Division regulates and must approve all medical devices to be marketed and sold in China. China has a three class risk classification system, with Class I being the lowest risk to Class III being the highest risk. Home country approval (510(k), PMA clearance) is required as a prerequisite to any application. Additionally, the CFDA often tests finished devices at its own testing laboratory to confirm each device’s specifications. The approval process is typically lengthy. Licenses are valid for 4 years from date of issuance and require renewal prior to expiration. The CFDA requires a license holder for any foreign manufacturer who must have a registered business inside of China.

There can be no assurance that new laws or regulations or new interpretations of laws and regulations regarding the release or sale of medical devices will not delay or prevent sale of our current or future products.

Third-Party Reimbursement

United States

Healthcare providers that purchase medical devices generally rely on third-party payors, including the Medicare and Medicaid programs and private payors (such as indemnity insurers, employer group health insurance programs, and managed care plans) to reimburse all or part of the cost of those products. As a result, demand for our products is and will continue to be dependent in part on the coverage and reimbursement policies of these payors. The manner in which reimbursement is sought and obtained varies based upon the type of payor involved and the setting in which the product is furnished and utilized. Furthermore, payments from Medicare, Medicaid, and other third-party payors are subject to legislative and regulatory changes and are susceptible to budgetary pressures.

In the United States, third-party payors generally pay healthcare providers directly for the procedures they perform and in certain instances for the products they use. Alternatively, third-party payors may reimburse patients for all or part of the charges that patients pay for procedures and the products used in connection with those procedures. In either case, our sales volumes depend on the extent to which third-party payors cover our products and the procedures in which they are used. In general, a third-party payor only covers a medical product or procedure when the plan administrator is satisfied that the product or procedure is medically necessary because it improves health outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance or approval for marketing by the FDA, there is no assurance that third-party payors will cover the cost of the device and related procedures in which the device is used.

In many instances, third-party payors cover the procedures performed using our products using price fee schedules that do not vary reimbursement to reflect the cost of the products and equipment used in performing those procedures. In other instances, payment or reimbursement is separately available for the products and equipment used, in addition to payment or reimbursement for the procedure itself. Even if coverage is available, third-party payors may place restrictions on the circumstances in which they provide coverage or may offer reimbursement that is not sufficient to cover the cost of our products. Many of the products that compete with ours are less expensive. Therefore, although coverage may be available for our products and the related procedures, the levels of approved coverage may not be sufficient to justify using our products instead of those of competitors.

Finally, the advent of contracted fixed rates per procedure has made it difficult to receive separate reimbursement for disposable products, even if the use of these products improves clinical outcomes. In addition, many third-party

14

payors are moving to managed care systems in which providers contract to provide comprehensive healthcare for a fixed cost per person. Managed care providers often attempt to control the cost of healthcare by authorizing fewer elective surgical procedures. Under current prospective payment systems, such as the diagnosis-related group system and the hospital out-patient prospective payment system, both of which are used by Medicare and in many managed care systems used by private third party payors, the reimbursement for our products will be incorporated into the overall reimbursement of a procedure, and there will be no separate reimbursement for our products. As a result, we cannot be certain that hospital administrators and physicians will purchase our products.

If hospitals and physicians cannot obtain adequate reimbursement for our products or the procedures in which they are used, our business, financial condition, and results of operations could suffer a material adverse impact.

Non-U.S.

Our success in non-U.S. markets will depend largely upon the availability of reimbursement from the third-party payors through which healthcare providers are paid in those markets. Reimbursement and healthcare payment systems in non-U.S. markets vary significantly by country. The main types of healthcare payment systems are government sponsored healthcare and private insurance. As in the United States, reimbursement is subject to legislative and regulatory changes and is susceptible to budgetary pressures. Reimbursement approval must be obtained individually in each country in which our products are marketed. Outside the United States, we may pursue reimbursement approval in those countries in which we sell directly to the hospital. In other markets, we generally rely on the distributors who sell our products to obtain reimbursement approval in those countries in which they will sell our products. There can be no assurance that reimbursement approval will be received.

Fraud and Abuse Laws

We may directly or indirectly be subject to various federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws. In particular, the federal healthcare program Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving, or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for, or recommending a good or service for which payment may be made in whole or part under federal healthcare programs, such as the Medicare and Medicaid programs. Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment, and possible exclusion from Medicare, Medicaid, and other federal healthcare programs. The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. In implementing the statute, the Office of Inspector General, or OIG, has issued a series of regulations, known as the “safe harbors.” These safe harbors set forth provisions that, if all their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the Anti-Kickback Statute. The failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy each applicable element of a safe harbor may result in increased scrutiny by government enforcement authorities, such as the OIG.

Patient Protection and Affordable Care Act

In March 2010, significant reforms to the U.S. healthcare system were adopted in the form of the Patient Protection and Affordable Care Act (the PPACA). The PPACA includes provisions that, among other things, require detailed public disclosure of compensation, gifts and any other transfers of value made to health care professionals and teaching hospitals, beginning in 2014.

Employees

We had 334 employees, including 328 full-time employees, at December 31, 2013.

Item 1A. Risk Factors

The following important factors, among others, could cause our actual operating results to differ materially from those indicated or suggested by forward-looking statements made in this Form 10-K or presented elsewhere by management from time to time. Investors should carefully consider the risks described below before making an investment decision. The risks described below are not the only ones we face. Additional risks not presently known to us or that we currently believe are not material may also significantly impair our business operations. Our business could be harmed by any of these risks. The trading price of our common stock could decline due to any of these risks, and investors may lose all or part of their investment.

Risks Related to Our Business

We may experience significant fluctuations in our quarterly and annual results.

Fluctuations in our quarterly and annual financial results have resulted and will continue to result from numerous factors, including:

• changes in the mix of products we sell;

• strategic actions by us, such as acquisitions of businesses, products, or technologies;

• the divestiture or discontinuation of a product line or other revenue generating activity, such as our stent grafts;

• the relocation and integration of manufacturing operations and other strategic restructuring, such as the transfer of XenoSure production and the transfer of production of Clinical Instruments’ devices;

• adverse regulatory actions which may necessitate recalls of our products or warning letters that negatively affect the markets for our products;

• our determination whether or not to continue the payment of quarterly cash dividends;

• our determination whether or not to undertake or continue share repurchases;

• costs incurred by us in connection with the termination of contractual and other relationships, including distributorships;

• our ability to collect outstanding accounts receivable in selected countries outside of the United States;

• the expiration or exhaustion of deferred tax assets such as net operating loss carry-forwards;

• effects of domestic and foreign economic conditions and exchange rates on our industry and/or customers;

• increased product and price competition, due to the regulatory landscape, market conditions or other factors; and

• the loss of any significant customer, especially in regard to any product that has a limited customer base.

These factors, some of which are not within our control, may cause the price of our common stock to fluctuate substantially. If our quarterly operating results fail to meet or exceed the expectations of securities analysts or investors, our stock price could drop suddenly and significantly. We believe the quarterly comparisons of our financial results are not always meaningful and should not be relied upon as an indication of our future performance.

If we are unable to expand our product offerings, we may not achieve our growth objectives and our results of operations could suffer.

The treatment of peripheral vascular disease is shifting from open vascular surgery to minimally invasive endovascular procedures, and many of our products are used primarily or exclusively in open vascular surgery procedures. We market and sell our products primarily to vascular surgeons, and the majority of our marketing

17

efforts and sales relate to products used in open vascular surgery rather than in endovascular procedures. The transactions we completed in 2011 further concentrated our focus on open vascular procedures. For instance, in 2011 we divested a large portion of our endovascular product portfolio, our TAArget Thoracic Stent Graft and our UniFit Abdominal Stent Graft, and also ended our relationship with Endologix, Inc. for distribution of its Powerlink stent graft in Europe. We may not be able to compete effectively with our competitors unless we can keep pace with existing or new products and technologies in the vascular device market and the minimally invasive endovascular procedure market, in particular. Our success in developing and commercializing new products and new versions of our existing products is affected by our ability to:

• identify in a timely manner new market trends and customer needs;

• keep pace with technological changes and industry standards;

• obtain regulatory clearance or approval of new products and technologies;

• successfully develop cost-effective manufacturing processes for such products;

• commercially introduce such products and technologies; and

• achieve market acceptance.

If we are unable to expand our product offerings, we may not achieve our growth objectives and our results of operations could suffer.

We may acquire businesses and assets in the future. We may experience difficulties in completing the integration of these acquisitions into our business, or we may not realize the anticipated benefits of these acquisitions.

In order to expand our product offerings, we have completed fourteen acquisitions, and a key part of our strategy is to acquire additional businesses, products, or technologies in the future. Our growth strategy depends in part upon our ability to identify, negotiate, complete, and integrate suitable acquisitions. If we are unable to complete acquisitions on satisfactory terms or at all, our growth objectives and sales could be negatively affected.

Even if we complete acquisitions, we may experience:

• difficulties in integrating any acquired businesses, personnel, and products into our existing business;

• difficulties in integrating manufacturing operations into our existing business or successfully replicating manufacturing processes at new manufacturing facilities;

• the sudden reduction in volume or loss of orders from a key customer, particularly where the acquired company has concentrated sales;

• diversion of our management’s time and attention from other business concerns;

• higher costs of integration than we anticipated;

• unknown or unanticipated liabilities included as part of the acquisition;

• disputes or litigation with former owners related to contingent payments, liabilities assumed or not assumed or other matters;

• challenges resulting from limited or no prior experience in new markets or countries we may enter;

• the need to improve an acquired product in order to gain broader market acceptance;

• difficulties in retaining key employees of the acquired business who are necessary to manage these acquisitions;

• difficulties if the acquired company is remote or inconvenient to our Burlington, Massachusetts, headquarters;

18

• difficulties or delays in transitioning clinical studies or unfavorable results from such clinical studies;

• difficulties or delays in commercializing intellectual property that we acquire;

• difficulties in acquiring the rights to and protecting intellectual property;

• dilution as a result of equity financing required to fund acquisition costs; or

• debt as a result of debt financing required to fund acquisition costs, which would be senior to our common stock and would require interest payments to a lender.

We could also discover deficiencies withheld from us due to fraud or otherwise not uncovered in our due diligence prior to an acquisition, including deficiencies in internal controls, data adequacy and integrity, product quality, and regulatory compliance, as well as undisclosed contractual or other liabilities and product liabilities, any of which could result in us becoming subject to penalties or other liabilities. Any of these difficulties could negatively impact our ability to realize the intended and anticipated benefits that we currently expect from our acquisitions or from acquisitions we complete in the future and could harm our financial condition and results of operations.

For instance, in October 2012, we acquired the manufacturing and distribution rights of the XenoSure biological patch from Neovasc Inc. and its wholly-owned subsidiary. We have begun manufacturing the XenoSure biological patch in our Burlington, Massachusetts headquarters, though we continue to purchase product from Neovasc Inc. We expect this transition to our Burlington facility to be complete in the second half of 2014. We expect the transition to negatively impact gross margins on our biologic vascular patch in 2014, and to improve our biologic vascular patch gross margins beginning in 2015; however, there can be no assurance that these results will be achieved, if at all. Further, the production of the XenoSure biological patch is our first experience in manufacturing biological tissues. There can be no assurance that we will not experience delays or additional expenses associated with the transfer of this patch and there can be no assurance that our current supply agreement with Neovasc will be sufficient to meet sales demand as we continue to transition manufacturing.

Additionally, in January 2014, we initiated a project to transfer the manufacturing of the newly acquired Clinical Instruments devices to our facility in Burlington. We expect the transfer to be complete in the second quarter of 2014; however there can be no assurances that this will be achieved on the expected timetable or that transfer costs won’t exceed our expectations. Further, the manufacturing transfer may result in a shortage of Clinical Instruments devices, which could negatively impact our sales.

For any of these reasons or as a result of other factors, we may not realize the anticipated benefits of our acquisitions and our operating results may be harmed.

If we do not realize the expected benefits from our cost-cutting measures announced in February 2014, our financial condition and operating results could be adversely affected.

In February 2014, we announced that we had initiated a plan intended to improve operational efficiencies. These actions include a reduction in force of approximately 10% of our workforce and other cost-cutting measures. We cannot guarantee that we will be able to realize the cost savings and other anticipated benefits from such actions or that such actions will not interfere with our ability to achieve our business objectives. If we are unable to realize the expected financial benefits and operational efficiencies from these actions, our financial condition and operating results could be adversely affected.

We face intense competition from other companies, technologies, and alternative medical procedures and we may not be able to compete effectively.

The markets in which we compete are highly competitive, subject to change, and significantly affected by new product introductions and other activities of industry participants. Although no one company competes against us in all of our product lines, a number of manufacturers of peripheral vascular devices have substantially

19

greater capital resources, larger customer bases, broader product lines, larger sales forces, greater marketing and management resources, larger research and development staffs, and larger facilities than ours; have established reputations with our target customers; and have developed worldwide distribution channels that are more effective than ours. Our competitors could elect to devote additional resources to the markets in which we currently enjoy less competition. Also, although we currently have leading market positions in the markets for some of our products, this is not true for the markets for all of our products. We have from time to time experienced difficulties competing against very large companies.

Recent industry consolidation could make the competitive environment more difficult for smaller companies like ours. Many of our competitors have substantially greater financial, technological, research and development, regulatory, marketing, sales, and personnel resources than we do. Certain of these competitors are able to manufacture at lower costs and may therefore offer comparable products at lower prices. Certain of these competitors may also have greater experience in developing and further improving products, obtaining regulatory approvals, and manufacturing and marketing such products. Certain of these competitors may obtain patent protection or regulatory approval or clearance, or achieve product commercialization, before us, any of which could materially adversely affect us. Further, if the trend towards endovascular procedures versus open vascular procedures continues or accelerates, our competitors may be better poised to take advantage of that trend, since our main product lines are used primarily in open vascular procedures. Because of the size of the vascular disease market opportunity, competitors and potential competitors have dedicated, and we believe will continue to dedicate, significant resources to aggressively promote their products. Also, new product developments that could compete with us more effectively are likely because the vascular disease market is characterized by extensive research efforts and technological progress. Competitors may develop technologies and products that are safer, more effective, easier to use, less expensive, or more readily accepted than ours. Their products could make our technology and products obsolete or noncompetitive. Our competitors may also be able to achieve more efficient manufacturing and distribution operations than we can. In addition, many of our products face competition from alternative procedures that utilize a different kind of medical device that we do not currently sell. Increased competition could also result in price reductions and loss of market share, any of which could result in lower revenues and reduced gross profits.

If we fail to convert additional countries or products from distributor sales to direct sales, or encounter difficulties in effecting such conversions, our results of operations could suffer.

We have a history of converting international distributor sales to direct sales by buying out our distributors and selling directly to hospitals through our own sales representatives. In the future, we intend to convert select other countries and products from distributor sales to direct sales. Such conversions typically result in disruptions in our sales in the applicable geographies. These transitions may also have an adverse effect on our cash flow from operations because distributors, unlike direct sales personnel, pay us for inventory that they stock for later sale. In addition, switching to a direct sales force may subject us to longer customer collection times and larger bad debt expense, since we would be required to collect customer payments directly rather than through a distributor.

Our distribution agreements are typically exclusive with terms of up to three years. These agreements may temporarily constrain our ability to convert certain countries or products from a distributor to a direct sales model. Further, even where the payment of compensation is not required by contract or local law, it may be prudent to make such a payment in order to assure a successful market transition. For example, we paid consulting and transition services fees to our former distributor in Japan in connection with the conversion to direct sales in a specific territory in Japan even though not required under an existing contract, because the absence of cooperation by a distributor may result in the erosion of our customer base, which could harm our ability to sell our product in that country.

Following termination of any distribution relationship, we may encounter difficulties in transitioning to a direct-sales model in any country in question. It may take us longer than expected to find sufficient qualified sales personnel to establish an effective sales force, which could negatively impact projected sales. If a distributor sold

20

our products through a network of sales agents, rather than exclusively through its own personnel, we may not be able to establish relationships with all members of that network, temporarily limiting our access to the existing market. Similarly, failure to maintain or quickly re-establish a distributor’s close relationships with the physicians who use our products could cause a drop in sales. Further, it may be difficult or impossible to transfer the assignment of a distributor’s rights to sell our products, and as a result sales to customers may be delayed until a new agreement or approval is obtained. The transition to a direct sales model may also require us to incur additional expenses and meet regulatory requirements that were previously the responsibility of the distributor. As a result of these risks, there can be no assurance that we will be successful in transitioning to a direct sales model in the countries that we select, and difficulties that we encounter in these transitions could negatively affect our business.

Current economic instability may harm our operating results.

Since 2011, financial markets and the economies in southern Europe have experienced disruption and volatility and conditions could worsen. As a result, the economic environment may, among other things:

• create downward pressure on the pricing of our products;

• adversely affect the collection of accounts receivable, particularly in regions such as Italy, Spain, and Greece;

• increase the sales cycle for certain of our products, resulting in higher levels of inventory;

• slow the adoption of new technology;

• adversely affect our customers, causing them to reduce spending; and

• adversely affect our suppliers, which could disrupt our ability to produce our products.

Any of these conditions could harm our operating results and liquidity.

If we are unable to increase our selling prices to customers, or if we are required to make price concessions, our rate of net sales growth could be reduced and our operating results could suffer.

In the years ended December 31, 2013, 2012 and 2011, a material portion of our increases in net sales was driven by higher average selling prices to our hospital customers across several of our product lines, particularly with respect to sales occurring in the United States. We have in the past been able to rely upon our intellectual property position, our well-known brands, our established reputation in the vascular surgery device marketplace, and, in some cases, an absence of competition, to implement price increases. However, the magnitude of the price increases we have been able to implement has declined over time.

We may become unable to implement further increases in the selling prices of our products:

• if healthcare spending is reduced, particularly in the United States, in response to government-enacted healthcare reform, general economic conditions, or the influence of accountable care organizations;

• if the reimbursement rates for the medical procedures in which our products are used are reduced or limited; or

• if competitors introduce lower-priced products of comparable safety and efficacy.

We also expect marketplace changes to increasingly place pressure on medical device pricing as hospitals join group purchasing organizations, integrated delivery networks and other groups that seek to aggregate purchasing power.

If we become unable to raise selling prices, or if we are required to make price concessions, it could reduce our rate of net sales growth and harm our operating results.

21

Our devices may not achieve market acceptance, which could adversely affect our business.

Some of our devices have been recently introduced into the market, including the MultiTASC Dissection/Transection Device, the 1.5mm Expandable LeMaitre Valvulotome and the AlboSure Vascular Patch, and we cannot assure you that any of those devices will achieve market acceptance. The same is true of new devices that we may acquire or internally develop in the future. The marketing of our products requires a significant amount of time and expense in order to identify and develop relationships with the physicians who may use our products, invest in training and education with these physicians, and employ a sales force that is large enough to interact with the targeted physicians, with no assurance of success. In some cases, our devices may face competition from devices marketed by our competitors, and our customers may not prefer our devices. In other cases, our devices may be used in new procedures and techniques, and if physicians do not adopt these procedures and techniques, demand for these devices would fail to develop. For example, sales of our The UnBalloon Non-Occlusive Modeling Catheter have not met our expectations since launching in 2010, despite its redesign. If our products do not gain market acceptance, our business could be adversely affected.

The risks inherent in operating internationally and the risks of selling and shipping our products and of purchasing our components and products internationally may adversely impact our net sales, results of operations, and financial condition.

We derive a significant portion of our net sales from operations in markets outside of the United States. For the year ended December 31, 2013, 34% of our net sales were derived from our operations outside of the Americas. Our international sales operations expose us and our representatives, agents, and distributors to risks inherent in operating in foreign jurisdictions. These risks include:

• fluctuations in foreign currency exchange rates;

• the imposition of additional U.S. and foreign governmental controls or regulations, including export licensing requirements, duties and tariffs, and other trade restrictions;

• the risk of non-compliance with the Foreign Corrupt Practices Act by our sales representatives or our distributors;

• the imposition of U.S. and/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;

• a shortage of high-quality sales personnel and distributors;

• loss of any key personnel who possess proprietary knowledge, or who are otherwise important to our success in certain international markets;

• 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 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;

• pricing pressure that we may experience internationally;

• laws and business practices favoring local companies;

• longer payment cycles;

• difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;

• difficulties in enforcing or defending intellectual property rights;

• exposure to different legal and political standards; and

• political, economic, and/or social instability.

22

We cannot assure you that one or more of these factors will not harm our business. Any material decrease in our international sales would adversely impact our net sales, results of operations, and financial condition.

We depend on single- and limited-source suppliers for some of the components to our products, as well as for acquired products that have not been transitioned to in-house manufacture, and if any of those suppliers are unable or unwilling to supply them on acceptable terms or otherwise, it could limit our ability to deliver our products to our customers on a timely basis or at all.

We rely on single- and limited-source suppliers for some of our important product components, as well as for products we have acquired that are not manufactured in-house. For example, our TRIVEX system and associated disposables, as well as our EndoRE remote endarterectomy product line, are manufactured for us by third-party suppliers. There are relatively few, or in some cases no, alternative, validated sources of supply for these components and products. We do not have supply agreements with most of these suppliers, and instead place orders on an as-needed basis. These suppliers could discontinue or be rendered incapable of the manufacture or supply of these components or products at any time. We do not carry a significant inventory of these components and products. Identifying and qualifying additional or replacement suppliers, if required, may not be accomplished quickly or at all and could involve significant additional costs. Any supply interruption from our vendors or failure to obtain additional vendors for any of the components used to manufacture our products would limit our ability to manufacture our products, may result in production delays and increased costs, and may limit our ability to deliver products to our customers. If we are unable to identify alternate sources of supply for the components, we would have to modify our products to use substitute components, which may cause delays in shipments, increase design and manufacturing costs, and increase prices for our products. We cannot assure you that any such modified products would be as effective as the predecessor products, or that such modified products would gain market acceptance. This could lead to customer dissatisfaction and damage to our reputation and our financial condition or results of operations may be harmed.

Any disruption in our manufacturing facilities could harm our results of operations.

Our principal worldwide executive, distribution, and manufacturing operations are located at adjacent 27,098 square foot and 27,289 square foot leased facilities located in Burlington, Massachusetts, with the lease of an additional 15,642 square feet to commence in 2015. These facilities and the manufacturing equipment we use to produce our products would be difficult to replace and could require substantial lead-time to repair or replace in the event of a natural or man-made disaster. In such event, we could not shift production to alternate manufacturing facilities, and we would be forced to rely on third-party manufacturers. Although we carry insurance for damage to our property and the disruption of our business from casualties, such insurance may not be sufficient to cover all of our potential losses, including potential damage to our reputation, and may not continue to be available to us on acceptable terms, or at all.

Our focus on the needs of vascular surgeons could harm our business if interventional cardiologists and interventional radiologists perform a greater percentage of new procedures that replace those procedures traditionally performed by vascular surgeons, or if vascular surgeons increasingly specialize in procedures for which we do not sell devices.

The treatment of peripheral vascular disease is shifting from open vascular surgery to minimally invasive endovascular procedures. We market and sell our products primarily to vascular surgeons, and the majority of our marketing efforts and sales relate to products used in open vascular surgery rather than in endovascular procedures. The transactions we completed in 2011 further concentrated our focus on open vascular procedures. In 2011 we divested a large portion of our endovascular product portfolio, our TAArget Thoracic Stent Graft and our UniFit Abdominal Stent Graft and ended our distribution of the Endologix Powerlink stent graft.

In addition to performing traditional open surgical procedures, vascular surgeons in growing numbers also perform minimally invasive, image-guided interventional procedures for peripheral vascular disease. However, vascular surgeons may not adopt these procedures in the numbers we expect and instead these procedures may be

23

largely performed by interventional cardiologists and interventional radiologists. Many of our competitors have focused their sales efforts on these interventionalists. If interventional cardiologists and interventional radiologists perform a greater percentage of these new procedures than we expect, our net sales may decline.

Moreover, demographic trends and other market factors, such as reimbursement rates, are driving vascular surgeons in the United States and potentially in other markets to increasingly specialize in certain kinds of procedures, such as endovascular therapies and the creation and maintenance of dialysis access sites. Sometimes these physicians will discontinue performing other vascular procedures. If this trend continues, it could lead to the fragmentation of our customer base, which would reduce cross-selling opportunities and the efficiency of each sales call by our sales representatives, which in turn would negatively impact our business.

The use or misuse of our products may result in injuries that lead to product liability suits, which could be costly to our business.

If our products are defectively designed, manufactured, or labeled, contain defective components, or are misused, or if our products are found to have caused or contributed to injuries or death, we may become subject to costly litigation by our customers or their patients. Although we offer training for physicians in the use of some of our products, we do not require that physicians be trained in the use of our products, and physicians may use our products incorrectly or in procedures not contemplated by us. We are from time to time involved in product liability claims. Product liability claims could divert management’s attention from our core business, be expensive to defend, and result in sizable damage awards against us. Claims of this nature may also adversely affect our reputation, which could damage our position in the market and subject us to product recalls.

We cannot assure you that our product liability insurance coverage will be sufficient to satisfy any claim made against us. Further, we may not be able to maintain the same level of coverage, and we may not be able to obtain adequate coverage at a reasonable cost and on reasonable terms, if at all. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing coverage in the future. Additionally, if any such product liability claim or series of claims is brought against us for uninsured liabilities or is in excess of our insurance coverage, our business could be harmed.

From time to time, we are involved in litigation where the outcome is uncertain and which could entail significant expense.

As is the case with many global companies, we are subject, from time to time, to litigation, including product liability suits, as described above. Because the outcome of litigation is inherently difficult to predict, it is possible that the outcome of litigation could entail significant cost for us and harm our business. The fact that we operate in international markets also increases the risk that we may face legal exposures as we seek to comply with a large number of varying legal and regulatory requirements. Any successful claim against us could adversely affect our business, financial condition and results of operations.

Risks Related to the Regulatory Environment

Oversight of the medical device industry might affect the manner in which we may sell medical devices and compete in the marketplace.

There are laws and regulations that govern the means by which companies in the healthcare industry may market their products to healthcare professionals and may compete by discounting the prices of their products, including for example, the federal Anti-Kickback Statute, the federal False Claims Act, the federal Health Insurance Portability and Accountability Act of 1996, state law equivalents to these federal laws that are meant to protect against fraud and abuse and analogous laws in foreign countries. Violations of these laws are punishable by criminal and civil sanctions, including, but not limited to, civil and criminal penalties, damages, fines,

24

exclusion from participation in federal and state healthcare programs, including Medicare and Medicaid. Although in structuring our sales and marketing practices and customer discount arrangements we strive to comply with those laws and regulations, we cannot assure you that:

• government officials charged with responsibility for enforcing those laws will not assert that our sales and marketing practices or customer discount arrangements are in violation of those laws or regulations; or

• government regulators or courts will interpret those laws or regulations in a manner consistent with our interpretation.

Federal and state laws are also sometimes open to interpretation, and from time to time we may find ourselves at a competitive disadvantage if our interpretation differs from that of our competitors.

In January 2004, AdvaMed, the principal United States trade association for the medical device industry, put in place a model “code of conduct” that sets forth standards by which its members should abide in the promotion of their products, which was revised in 2009. We have in place policies and procedures for compliance that we believe are at least as stringent as those set forth in the revised AdvaMed Code, and we provide routine training to our sales and marketing personnel on our policies regarding sales and marketing practices. Nevertheless, the sales and marketing practices of our industry have been the subject of increased scrutiny from federal and state government agencies, and we believe that this trend will continue. For example, recent federal legislation and state legislation require detailed disclosure of gifts and other remuneration made to health care professionals. In addition, prosecutorial scrutiny and governmental oversight, on the state and federal levels, over device companies regarding the retention of healthcare professionals as consultants has limited the manner in which medical device companies may retain healthcare professionals as consultants.

Our business is subject to complex, costly, and burdensome regulations. We could be subject to significant penalties if we fail to comply.

The production and marketing of our products and our ongoing research and development are subject to extensive regulation and review by numerous governmental authorities both in the United States and abroad. U.S. and foreign regulations applicable to medical devices are wide-ranging and govern, among other things, the testing, marketing, and premarket clearance or approval of new medical devices, in addition to regulating manufacturing practices, reporting, promotion and advertising, importing and exporting, labeling, and record-keeping procedures.

Our failure to comply with applicable regulatory requirements could result in governmental agencies or a court taking action, including any of the following:

• issuing public warning letters to us;

• imposing fines and penalties on us;

• issuing an injunction preventing us from manufacturing or selling our products;

• bringing civil or criminal charges against us;

• delaying the introduction of our new products into the market;

• ordering a recall of, or detaining or seizing, our products; or

• withdrawing or denying approvals or clearances for our products.

If any or all of the foregoing were to occur, our business, results of operations, and reputation could suffer.

If we are not successful in obtaining and maintaining clearances and approvals from governmental agencies, we will not be able to sell our products, and our future growth will be significantly hampered.

Our products require premarket clearance or approval in the United States and the CE Mark or other approvals in foreign countries where they are sold. Each medical device that we wish to market in the United

25

States generally must receive either 510(k) clearance or approval of a premarket application, or PMA, from the FDA before the product can be marketed or sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearance procedure usually takes from three to twelve months from the date the FDA receives the application, but may take significantly longer. Although 510(k) clearances have been obtained for nearly all of our current products that require 510(k) clearances, the FDA may condition, limit or prohibit our sales of these products if safety or effectiveness problems develop with the devices. Our new products or significantly modified marketed products could be denied 510(k) clearance and required to undergo the more burdensome PMA approval process if they are not found to be substantially equivalent.

The PMA approval process is much more costly, lengthy, and uncertain than the premarket notification process. It generally takes from six months to three years from the date the application is submitted to, and filed with, the FDA, and may take even longer. Achieving premarket approval typically requires extensive clinical trials and may require the filing of numerous amendments with the FDA over time. We do not have significant experience in obtaining PMA approval for our products.

The FDA has proposed changes for which FDA clearance to market would possibly require clinical data, more extensive manufacturing information and post market data. As part of the 510(k) reform, the FDA proposes to issue regulations defining grounds and procedures for rescission of 510(k) applications that have previously been cleared to market. The FDA may also require the more extensive PMA process for certain products. Our ability to market our products outside the United States is also subject to regulatory approval, including our ability to demonstrate the safety and effectiveness of our products in the clinical setting.

Even if regulatory approval or clearance of a product is granted, the approval or clearance could limit the uses or the claims for which the product may be labeled and promoted, which may limit the market for our products. If we do not obtain and maintain foreign regulatory or FDA approval with respect to our products, as applicable, we will not be able to sell our products, and our future growth will be significantly hampered.

If we or some of our suppliers fail to comply with the FDA’s Quality System Regulation and other applicable post market requirements, our manufacturing operations could be disrupted, our product sales and profitability could suffer, and we may become subject to a wide variety of FDA enforcement actions.

After a device is placed on the market, numerous regulatory requirements apply. We are subject to inspection and marketing surveillance by the FDA to determine our compliance with all regulatory requirements. If the FDA finds that we have failed to comply with any regulatory requirements, it can institute a wide variety of enforcement actions.

We and some of our suppliers must comply with the FDA’s Quality System Regulation, which governs the methods used in, and the facilities and controls used for, the design, testing, manufacture, control, quality assurance, installation, servicing, labeling, packaging, storage, and shipping of medical devices. The FDA enforces the Quality System Regulation through pre-announced and unannounced inspections. We have been, and anticipate in the future being, subject to such inspections by the FDA and other regulatory bodies. The timing and scope of future audits is unknown and it is possible, despite our belief that our quality systems and the operation of our manufacturing facilities will remain in compliance with U.S, and non-U.S. regulatory requirements, that a future audit may result in one or more unsatisfactory results. If we or one of our suppliers fails a Quality System Regulation inspection, or if a corrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action against us, and our operations could be disrupted and our manufacturing delayed.

We are also subject to the FDA’s general prohibition against promoting our products for unapproved or off-label uses and to the medical device reporting, or MDR, regulations that require us to report to the FDA if our products may have caused or contributed to a death or serious injury, or if our device malfunctions and a recurrence of the malfunction would likely result in a death or serious injury. We must also file reports with the FDA of some device corrections and removals, and we must adhere to the FDA’s rules on labeling and promotion. If we fail to

26

comply with these or other FDA requirements or fail to take adequate corrective action in response to any significant compliance issue raised by the FDA, the FDA can take significant enforcement actions, which could harm our business, results of operations, and our reputation.

In addition, most other countries, such as Japan, require us to comply with manufacturing and quality assurance standards for medical devices that are similar to those in force in the United States before marketing and selling our products in those countries. If we fail to comply, we would lose our ability to market and sell our products in those foreign countries.

Even after our products have received marketing approval or clearance, our products may be subject to product recalls or product approvals and clearances could be withdrawn due to failure to comply with regulatory standards or the occurrence of unforeseen problems following initial approval.

Our products, marketing, sales and development activities, and manufacturing processes are subject to extensive and rigorous regulation by the FDA, by comparable agencies in foreign countries, and by other regulatory agencies and governing bodies. These authorities have been increasing their scrutiny of our industry. If those regulatory bodies feel that we have failed to comply with regulatory standards or if we encounter unforeseen problems following initial approval of our products, there can be no assurance that any approval will not be subsequently withdrawn, suspended or conditioned upon extensive post-market study requirements, even after products have received marketing approval or clearance. Further, due to the increased scrutiny of our industry by the various regulatory agencies and the interconnectedness of the various regulatory agencies, particularly within the European Union, there is also no assurance that withdrawal or suspension of any of our product approvals by any single regulatory agency will not precipitate one or more additional regulatory agencies from also withdrawing or suspending approval of any such product.

In the event that any of our products proves to be defective, we can voluntarily recall, or the FDA or foreign equivalent could require us to implement a recall of, any of our products, and, if someone is harmed by a malfunction or a product defect, we may experience product liability claims for such defects. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital and may harm our reputation and financial results. Future recalls or claims could also result in significant costs to us and significant adverse publicity, which could harm our ability to market our products in the future.

In the event that any of our products proves to be defective, we can voluntarily recall, or the FDA or foreign equivalent could require us to implement a recall of or prohibit the sale of, any of our products. For example, in 2011, 2012, and 2013, we voluntarily recalled certain lots of our AlboGraft vascular graft. In March 2012, regulatory agencies in France and the UK issued Prohibition Notices, which prohibited us from selling AlboGraft vascular grafts in these countries pending our ability to address their concerns. Though these prohibitions were lifted by the end of 2012 and we believe that the failures associated with those lots were isolated, there can be no assurance that there will not be a recurrence or that other problems related to our AlboGraft vascular graft will not develop in the future.

Additionally, if someone is harmed by a malfunction or a product defect, we may experience product liability claims for such defects. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital and may harm our reputation and financial results. Future recalls or claims could also result in significant costs to us and significant adverse publicity, which could harm our ability to market our products in the future.

The adoption of healthcare reform in the United States may adversely affect our business, results of operations and/or financial condition.

In March 2010, significant reforms to the U.S. healthcare system were adopted in the form of the Patient Protection and Affordable Care Act (PPACA). The PPACA includes provisions that, among other things, reduce and/or limit Medicare reimbursement, require all individuals to have health insurance (with limited exceptions)

27

and impose new and/or increased taxes. Specifically, the law also requires the medical device industry to subsidize healthcare reform in the form of a 2.3% excise tax on U.S. sales of most medical devices beginning in 2013. In 2013, we paid an excise tax of approximately $0.6 million. Various healthcare reform proposals have also emerged at the state level. The PPACA and these proposals could reduce medical procedure volumes and impact the demand for our products or the prices at which we sell our products. In addition, the excise tax will increase our cost of doing business. The impact of the PPACA and these proposals could harm our operating results and liquidity.

Domestic and foreign legislative or administrative reforms resulting in restrictive reimbursement practices of third-party payors and cost containment measures could decrease the demand for products purchased by our customers, the prices that our customers are willing to pay for those products and the number of procedures using our devices.

Our products are purchased principally by hospitals or physicians which typically bill various third-party payors, such as governmental programs (e.g., Medicare, Medicaid and comparable foreign programs), private insurance plans and managed care plans, for the healthcare services provided to their patients. The ability of our customers to obtain appropriate reimbursement for products and services from third-party payors is critical to the success of our products because it affects which products customers purchase and the prices they are willing to pay. Reimbursement varies by country and can significantly impact the acceptance of new technology. Implementation of healthcare reforms in the United States and in significant overseas markets such as Germany, Japan, France and other countries may limit, reduce or eliminate reimbursement for our products and adversely affect both our pricing flexibility and the demand for our products. Even when we develop or acquire a promising new product, we may find limited demand for the product unless reimbursement approval is obtained from private and governmental third-party payors.

Major third-party payors for hospital services in the United States and abroad continue to work to contain healthcare costs through, among other things, the introduction of cost containment incentives and closer scrutiny of healthcare expenditures by both private health insurers and employers. For example, in an effort to decrease costs, certain hospitals and other customers may resterilize our products intended for a single use or purchase reprocessed products from third-party reprocessors in lieu of purchasing new products from us.

Further legislative or administrative reforms to the reimbursement systems in the United States and abroad, or adverse decisions relating to our products by administrators of these systems in coverage or reimbursement, could significantly reduce reimbursement for procedures using our medical devices or result in the denial of coverage for those procedures. Examples of these reforms or adverse decisions include price regulation, competitive pricing, coverage and payment policies, comparative effectiveness of therapies, technology assessments and managed-care arrangements. Any of such reforms or adverse decisions resulting in restrictive reimbursement practices or denials of coverage could have an adverse impact on the acceptance of our products and the prices that our customers are willing to pay for them.

If we do not comply with foreign regulatory requirements to market our products outside the United States, our business will be harmed.

Sales of medical devices outside the United States are subject to international regulatory requirements that vary from country to country. These requirements and the amount of time required for approval may differ from our experiences with the FDA in the United States. In some cases, we rely on our non-U.S. distributors to obtain premarket approvals, complete product registrations, comply with clinical trial requirements, and complete those steps that are customarily taken in the applicable jurisdictions to comply with governmental and quasi-governmental regulation. In the future, we expect to continue to rely on distributors in this manner in those countries where we continue to market and sell our products through them. Failure to satisfy these foreign regulations would impact our ability to sell our products in these countries and could cause our business to suffer. There can be no assurance that we will be able to obtain or maintain the required regulatory approvals in these countries.

28

Our products are regulated in the European Union under the European Medical Devices Directive (93/42/EC as amended by 2007/47/EC). In order to market our medical devices in the European Union, we are required to obtain CE mark certification, which denotes conformity to the essential requirements of the Medical Devices Directive. We have received CE mark certification to sell nearly all of our products. However, there can be no assurance that we will be able to obtain a CE mark for new products in the future or for modifications to our existing products or in the manufacturing of our products, and obtaining a CE mark may involve a significant amount of time and expense, stringent clinical and preclinical testing, or modification of our products and could result in limitations being placed on the use of our products in order to obtain approval.

Maintaining a CE mark is contingent upon our continued compliance with applicable European medical device requirements, including limitations on advertising and promotion of medical devices and requirements governing the handling of adverse events. There can be no assurance that we will be successful in maintaining the CE mark for any of our current products. In particular, adverse event reporting requirements in the European Union mandate that we report incidents which led or could have led to death or serious deterioration in health. Under certain circumstances, we could be required to or could voluntarily initiate a recall or removal of our product from the market in order to address product deficiencies or malfunctions. For instance, we initiated voluntary recalls of two lots of our AlboGraft vascular graft in each of October 2011, February 2012 and July 2013, respectively, in response to customer complaints of a manufacturing defect. Any recall of our products may harm our reputation with customers and divert managerial and financial resources.

Failure to receive or maintain approval would prohibit us from selling these products in member countries of the European Union, and would require significant delays in obtaining individual country approvals. If we do not receive or maintain these approvals, our business could be harmed.

Our manufacturing facilities are subject to periodic inspection by European regulatory authorities and Notified Bodies, and we must demonstrate compliance with the Medical Devices Directive. Our most recent periodic inspections by our European Notified Bodies were conducted in November and December 2013. Any failure by us to comply with European requirements in this regard may entail our taking corrective action, such as modification of our policies and procedures. In addition, we may be required to cease all or part of our operations for some period of time until we can demonstrate that appropriate steps have been taken. There can be no assurance that we will be found in compliance with such standards in future audits.

In Japan, the Ministry of Health, Labor and Welfare (MHLW) regulates medical devices through the Pharmaceutical Affairs Law, which was reformed effective April 1, 2005. The revisions to Japanese regulations have resulted in longer lead times for product approvals.

Any such delay in product registrations could have a negative impact on our results of operations.

Certain of our products contain materials derived from animal sources and may become subject to additional regulation.

Our AlboGraft Vascular Graft, AlboSure Vascular Patch, and XenoSure Biologic Patch products contain bovine tissue or material derived from bovine tissue. Products that contain materials derived from animal sources, including food, pharmaceuticals and medical devices, are increasingly subject to scrutiny in the media and by regulatory authorities. Regulatory authorities are concerned about the potential for the transmission of disease from animals to humans via those materials. This public scrutiny has been particularly acute in Japan and Western Europe with respect to products derived from animal sources, because of concern that materials infected with the agent that causes bovine spongiform encephalopathy, otherwise known as BSE or mad cow disease, may, if ingested or implanted, cause a variant of the human Creutzfeldt-Jakob Disease, an ultimately fatal disease with no known cure. Cases of BSE in cattle discovered in Canada and the United States have increased awareness of the issue in North America. Certain regions or countries, such as Europe, have issued regulations that require our products be processed from bovine tissue sourced from countries, like Australia, where no cases

29

of BSE have occurred. Products that contain materials derived from animals, including our products, may become subject to additional regulation, or even be banned in certain countries, because of concern over the potential for the transmission of infections agents. Significant new regulation, or a ban of our products, could impair our current business or our ability to expand our business.

Risks Related to Intellectual Property

If we fail to adequately protect our intellectual property rights, or prevent use of our intellectual property by third parties, we could lose a significant competitive advantage and our business may suffer.

Our success depends in part on obtaining, maintaining, and enforcing our patents, trademarks, and other proprietary rights, and our ability to avoid infringing on the proprietary rights of others. We take precautionary steps to protect our technological advantages and intellectual property. We rely upon patent, trade secret, copyright, know-how, and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual property rights and protect our products. These measures may only afford limited protection and may not:

• prevent our competitors from duplicating our products;

• prevent our competitors from gaining access to our proprietary information and technology; or

• permit us to gain or maintain a competitive advantage.

Furthermore, the patents associated with the Expandable LeMaitre Valvulotomes will expire in 2015. Valvulotomes were our highest net sales product line in 2013. With the pending expiration of patents associated with the Expandable LeMaitre Valvulotomes in 2015, it is possible that other manufacturers will attempt to market and sell valvulotomes substantially similar, or identical, to the Expandable LeMaitre Valvulotomes, though in 2013 we secured a patent in the US on the Over-The-Wire LeMaitre Valvulotome. To the extent any of these manufacturers are successful this could have an adverse impact on our business and harm our sales and operating results.

The issuance of a patent is not conclusive as to its validity or enforceability. Any patents we have obtained or will obtain in the future might also be invalidated or circumvented by third parties. In addition, our pending patent applications may not issue as patents or, if issued, may not provide commercially meaningful protection, as competitors may be able to design around our patents to produce alternative, non-infringing designs. Should such challenges to our patents be successful, competitors might be able to market products and use manufacturing processes that are substantially similar to ours.

Additionally, we may not be able to effectively protect our rights in unpatented technology, trade secrets, and confidential information. We have a policy of requiring key employees and consultants and corporate partners with access to trade secrets or other confidential information to execute confidentiality agreements. Our confidentiality agreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer, or disclosure of confidential information or inventions.

In addition, the laws of foreign countries may not protect our intellectual property rights effectively or to the same extent as the laws of the United States. If our intellectual property rights are not adequately protected, we may not be able to commercialize our technologies, products, or services and our competitors could commercialize similar technologies, which could result in a decrease in our sales and market share.

30

If third parties claim that we infringe upon their intellectual property rights, we may incur liabilities and costs, and we may have to redesign or discontinue selling the affected product.

The medical device industry is litigious with respect to patents and other intellectual property rights. Companies operating in our industry routinely seek patent protection for their product designs, and many of our principal competitors have large patent portfolios. Companies in the medical device industry have used intellectual property litigation to gain a competitive advantage. Whether a product infringes a patent involves complex legal and factual issues, the determination of which is often uncertain. We face the risk of claims that we have infringed on third parties’ intellectual property rights, and we cannot assure you that our products or methods do not infringe the patents or other intellectual property rights of third parties. Our efforts to identify and avoid infringing on third parties’ intellectual property rights may not always be successful. Any claims of patent or other intellectual property infringement, even those without merit, could:

• be expensive and time consuming to defend;

• result in us being required to pay significant damages to third parties for past use of the asserted intellectual property;

• harm our reputation;

• cause us to cease making or selling products that incorporate the challenged intellectual property;

• require us to redesign, reengineer, or rebrand our products, which may not be possible and could be costly and time consuming if it is possible to do so at all;

• require us to enter into royalty or licensing agreements in order to obtain the right to use a third party’s intellectual property, which agreements may not be available on terms acceptable to us or at all;

• divert the attention of our management and key personnel from other tasks important to the success of our business; or

• result in our customers or potential customers deferring or limiting their purchase or use of the affected products until resolution of the litigation.

It is also possible that one of our competitors could claim that our manufacturing process violates an existing patent. If we were unsuccessful in defending such a claim, we may be forced to stop production at one or more of our manufacturing facilities.

In addition, new patents obtained by our competitors could threaten a product’s continued life in the market even after it has already been introduced. If our business is successful, the possibility may increase that others will assert infringement claims against us.

If we believe our product is or may be the subject of a patent with a third party, we may attempt to reach a license agreement with them to manufacture, market, and sell these products. If we fail to reach an agreement with a third party patent holder that covers a product we offer, we could be required to pay significant damages to third parties for past use of the asserted intellectual property and may be forced to cease making or selling products that incorporate the challenged intellectual property.

In addition, we may become subject to interference proceedings conducted in the United States Patent Office or opposition proceedings conducted in foreign patent offices challenging the priority of invention or the validity of our patents. For example, in 2005 and 2006, respectively, Boston Scientific Corporation initiated opposition proceedings in the European Patent Office claiming that we were not the first to file a patent application on certain material. As a result of these opposition proceedings, some of our patent claims were canceled.

Risks Related to Our Common Stock

Our stock price may be volatile, and your investment in our common stock could suffer a decline in value.

There can be significant volatility in the market price and trading volume of equity securities that is unrelated to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. You may not be able to resell your shares at or above the price at which you purchased them due to fluctuations in the market price of our common stock caused by changes in our operating performance or prospects, a low volume of trading in our common stock, and other factors.

Some specific factors that may have a significant effect on our common stock market price include:

• actual or anticipated fluctuations in our operating results or future prospects;

• our announcements or our competitors’ announcements of new products;

• public concern as to the safety or efficacy of our products;

• the public’s reaction to our press releases, our other public announcements, and our filings with the SEC;

• our determination whether or not to continue the payment of quarterly cash dividends;

• our determination whether or not to undertake or continue a share repurchase program;

• strategic actions by us or our competitors, such as acquisitions, divestitures or restructurings;

• dilutive issuances of additional securities;

• changes in our growth rates or our competitors’ growth rates;

• developments regarding our patents or proprietary rights or those of our competitors;

• our inability to raise additional capital;

• changes in financial markets or general economic conditions, including those resulting from war, incidents of terrorism, and responses to such events;

• new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

• changes in accounting standards, policies, guidance, interpretations, or principles;

• light volume of trades of our common stock;

• the discontinuation of a product line or other revenue generating activity, such as our stent grafts;

• adverse regulatory actions which may necessitate recalls of our products or warning letters that negatively affect the markets for our products;

• sales of common stock by us or our directors, officers, or principal stockholders;

• our relatively small public float; and

• changes in stock market analyst recommendations or earnings estimates regarding our common stock, comparable companies, or our industry generally.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. A securities class action suit against us could result in substantial costs and divert our management’s attention and resources that would otherwise be used to benefit the future performance of our business.

32

Our directors and officers have significant voting power and may take actions that may not be in the best interests of our other stockholders.

Our directors and officers collectively control approximately 40% of our outstanding common stock, assuming the exercise of all options held by such persons. As a result, these stockholders, if they were to act together, would have substantial influence on most matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change in control, might adversely affect the market price of our common stock, and may not be fully aligned with the interests of our other stockholders.

We have not established a minimum dividend payment level for our common stockholders and there are no assurances of our ability to pay dividends to common stockholders in the future.

In February 2011, our Board of Directors adopted a quarterly dividend program for the purpose of returning capital to our stockholders. However, we have not established a minimum dividend payment level for our common stockholders and our ability to pay dividends may be harmed by the risks and uncertainties described in this Annual Report on Form 10-K and in the other documents we file from time to time with the SEC. Future dividends, if any, will be authorized by our Board of Directors and declared by us based upon a variety of factors deemed relevant by our directors, including, among other things, our financial condition, liquidity, earnings projections and business prospects. In addition, financial covenants in any credit facility to which we become a party may restrict our ability to pay future quarterly dividends. We can provide no assurance of our ability to pay dividends in the future.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our principal worldwide executive, distribution, and manufacturing operations are located at adjacent 27,098 square foot and 27,289 square foot leased facilities located in Burlington, Massachusetts, with the lease of an additional 15,642 square feet to commence in 2015. Our Burlington leases expire in 2023. In addition, our international operations are headquartered at a 12,841 square foot leased facility located in Sulzbach, Germany, with a lease expiring in 2016. In addition, we have smaller sales offices located in Australia, Canada, Italy, Japan, and Spain. Based on our current operating plans, we believe our current facilities are adequate.

Item 3. Legal Proceedings

In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, and threats of litigation consisting of intellectual property, commercial and other matters. While the outcome of these proceedings and claims cannot be predicted with certainty, there are no matters, as of December 31, 2013, that, in the opinion of management, might have a material adverse effect on our financial position, results of operations or cash flows.

Item 4. Mine Safety Disclosures

Not applicable.

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

The following discussion should be read in conjunction with our consolidated financial statements and the related notes contained elsewhere in this Annual Report on Form 10-K and in our other Securities and Exchange Commission filings. The following discussion may contain predictions, estimates, and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under “Risk Factors” and elsewhere in this Annual Report on Form 10-K. These risks could cause our actual results to differ materially from any future performance suggested below.

Overview

We are a medical device company that develops, manufactures, and markets medical devices and implants for the treatment of peripheral vascular disease. Our principal product offerings are sold throughout the world, primarily in the United States, the European Union and, to a lesser extent, Asia and the Pacific Rim. We estimate that the annual worldwide market for all peripheral vascular devices approximates $3 to $4 billion, within which our core product lines address roughly $800 million. We have grown our business by using a three-pronged strategy: competing in niche markets, expanding our worldwide direct sales force, and acquiring and developing complementary vascular devices. We have used acquisitions as a primary means of further accessing the larger peripheral vascular device market, and we expect to continue to pursue this strategy in the future. Additionally, we have increased our efforts to expand our vascular device offerings through new product development efforts. We currently manufacture most of our product lines in our Burlington, Massachusetts, headquarters.

Our products are used by vascular surgeons who treat peripheral vascular disease through both open surgical methods and endovascular techniques. In contrast to interventional cardiologists and interventional radiologists, neither of whom are certified to perform open surgical procedures, vascular surgeons can perform both open surgical and minimally invasive endovascular procedures, and are therefore uniquely positioned to provide a wider range of treatment options to patients.

Our principal product lines include the following: valvulotomes, balloon catheters, carotid shunts, biologic vascular patches, radiopaque marking tape, anastomotic clips, remote endarterectomy devices, laparoscopic cholecystectomy devices, vascular grafts, and powered phlebectomy.

To assist us in evaluating our business strategies, we regularly monitor long-term technology trends in the peripheral vascular device market. Additionally, we consider the information obtained from discussions with the medical community in connection with the demand for our products, including potential new product launches. We also use this information to help determine our competitive position in the peripheral vascular device market and our manufacturing capacity requirements.

Our business opportunities include the following:

• the long-term growth of our sales force in North America, Europe and Asia and the Pacific Rim, sometimes in connection with terminations of certain distributor relationships in order to expand our sales presence in new countries;

• the addition of complementary products through acquisitions;

• the updating of existing products and introduction of new products through research and development;

• the introduction of our products in new markets upon obtainment of regulatory approvals in these markets; and

• the consolidation of product manufacturing into our facilities in our Burlington, Massachusetts corporate headquarters.

We sell our products primarily through a direct sales force. As of December 31, 2013 our sales force was comprised of 85 sales representatives in North America, the European Union and Japan. We also sell our products in other countries through distributors. Our worldwide headquarters is located in Burlington, Massachusetts. Our international operations are headquartered in Sulzbach, Germany. We also have sales offices located in Tokyo, Japan, Mississauga, Canada, Madrid, Spain, Milan, Italy and Melbourne, Australia. In 2013, approximately 92% of our net sales were generated in markets in which we employ direct sales representatives.

In recent years we have experienced comparatively greater success in product markets characterized by low or limited competition, for example the markets for biologic patches and valvulotome devices. In the biologic patch market, we believe that we have been able to increase market share and increase selling prices. In the valvulotome market, we believe that we have been able to increase selling prices without compromising market share. There can be no assurance that we will not meet resistance to increased selling prices in the future. In contrast, we have experienced comparatively lesser success in highly competitive product markets such as polyester and ePTFE grafts, where we face stronger competition from larger companies with greater resources. While we believe that these challenging market dynamics can be mitigated by our strong relationships with our vascular surgeon customers, there can be no assurance that we will be successful in highly competitive markets.

In recent years we have also experienced comparatively greater success in geographic markets outside of the United States, including Europe and other non-traditional markets for our devices such as China and Saudi Arabia. Sales to these geographies generally include comparatively lower average selling prices, and to the extent that we continue to be successful in these markets, as well as successful at selling our biologic vascular patch device which carries a lower margin, we will likely experience downward pressure on our gross margin.

Because we believe that direct-to-hospital sales engender closer customer relationships, and allow for higher selling prices and gross margins, we periodically enter into transactions with our distributors to transition their sales of our medical devices to our direct sales organization:

• In October 2012, we entered into a definitive agreement with Schaublin Medica SA (Schaublin) to terminate its distribution of our products in Switzerland effective January 1, 2013. The agreement required us to pay approximately $0.2 million in exchange for the purchase of their customer list for our products, certain customer contracts, sales and marketing transition services, and minimal inventory.

• In December 2012, we entered into a definitive agreement with Trytech Corporation to terminate its distribution of our products in a certain Japanese territory effective as of April 1, 2013. The agreement required us to pay approximately $0.1 million in exchange for the purchase of their customer list for our products, certain customer contracts, sales and marketing transition services, and minimal inventory.

• In March 2013, we began shipping directly to Canadian hospitals from our sales office in Toronto, Canada.

39

• In October 2013, we entered into a definitive agreement with Medistim Norge AS (Medistim) to terminate its distribution of our products in Norway effective January 1, 2014. The agreement required us to pay approximately $0.2 million in exchange for the purchase of their customer list for our products, sales and marketing transition services, and minimal inventory.

• In October 2013, we entered into a definitive agreement with Tag Medical Pty Ltd (Tag) to terminate its distribution of our products in Australia effective January 1, 2014. The agreement required us to pay approximately $0.2 million in exchange for the purchase of their customer list for our products, certain customer contracts, sales and marketing transition services, and minimal inventory.

We anticipate that the expansion of our direct sales organization in Norway and Australia will result in increased sales and marketing expenses during 2014.

Our strategy for growing our business includes the acquisition of complementary product lines and companies and occasionally the discontinuance or divestiture of products or activities that are no longer complementary:

• In June 2011, we divested our TAArget and UniFit stent grafts to Duke Vascular, Inc. for $0.6 million. In addition, Duke Vascular, Inc. assumed our future obligations for the associated UNITE and ENTRUST clinical trials.

• In August 2011, we terminated our distribution of Endologix’s aortic stent graft products in Europe in exchange for $1.3 million.

• In October 2012, we acquired the manufacturing and distribution rights of the XenoSure biologic vascular patch from Neovasc, Inc. for $4.6 million, having previously been an exclusive distributor of the XenoSure biologic vascular patch since 2008.

• In July 2013, we acquired substantially all of the assets of Clinical Instruments International, Inc. (Clinical Instruments), a manufacturer of latex and latex free shunts and catheters, for $1.1 million.

• In August 2013, we acquired substantially all of the assets of InaVein, LLC (InaVein), a manufacturer of a varicose veins removal system. The purchase price consisted of $2.5 million plus contingent consideration totaling $1.4 million in 2014 and 2015, dependent on the sales performance of the acquired business and regulatory approval in China.

In addition to relying upon acquisitions to grow our business, we also rely on our product development efforts to bring differentiated technology and next-generation products to market. These efforts have led to the following recent product developments:

• In January 2012, we launched the Over-The-Wire LeMaitre Valvulotome.

• In April 2013, we launched the MultiTASC device.

• In May 2013, we launched the 1.5mm Expandable LeMaitre Valvulotome.

• In June 2013, we launched the AlboSure vascular patch.

In addition to our sales growth strategies, we have also executed several operational initiatives designed to consolidate and streamline manufacturing within our Burlington, MA facilities. We expect that these plant consolidations will result in improved control over our production capacity as well as reduced costs over the long-term. Our most recent manufacturing transitions included:

• In May 2011, we adopted a reorganization plan that was designed to eliminate redundant costs resulting from our 2010 acquisition of the LifeSpan vascular graft and to improve efficiencies in manufacturing operations. We have completed the transition of LifeSpan vascular graft manufacturing into our existing corporate headquarters in Burlington, Massachusetts.

40

• In November 2012, we initiated a project to build a third clean room for our newly acquired biologic vascular patch. We expect this transition to our Burlington facility to be complete in the second quarter of 2014. We expect the transition to negatively impact gross margins on our biologic vascular patch in 2014, and to improve our biologic vascular patch gross margins beginning in 2015; however, there can be no assurance that these results will be achieved. Further, the production of the biologic vascular patch is our first experience in manufacturing biological tissues. There can be no assurance that we will not experience delays or additional expenses associated with this transfer.

• In January 2014, we initiated a project to transfer the manufacturing of the newly acquired Clinical Instruments devices to our facility in Burlington. We expect the transfer to be complete in the second quarter of 2014; however there can be no assurances that this will be achieved on the expected timetable or that transfer costs won’t exceed our expectations. Further, the manufacturing transfer may result in a shortage of Clinical Instruments devices, which could negatively impact sales.

Our execution of these business opportunities may affect the comparability of our financial results from period to period and may cause substantial fluctuations from period to period, as we incur related restructuring and other non-recurring charges, as well as longer term impacts to revenues and operating expenditures. For example, in 2011 we exited the stent graft business, and realized gains of approximately $0.7 million in 2011 and $0.2 million in 2012 in connection with that exit. Separately, we recognized $1.1 million and $1.8 million of restructuring expenses in 2011 and 2010, respectively, related to the Biomateriali plant closure and relocation to Burlington, MA.

Fluctuations in the rate of exchange between the U.S. dollar and foreign currencies, primarily the Euro, affect our financial results. For the year ended December 31, 2013, approximately 34% of our sales were from outside the Americas. We expect that foreign currencies will continue to represent a similarly significant percentage of our sales in the future. Selling, marketing, and administrative costs related to these sales are largely denominated in the same respective currency, thereby partially mitigating our transaction risk exposure. However, most of our foreign sales are denominated in local currency, and if there is an increase in the rate at which a foreign currency is exchanged for U.S. dollars, it will require more of the foreign currency to equal a specified amount of U.S. dollars than before the rate increase. In such cases we will receive less in U.S. dollars than we did before the rate increase went into effect.

Net Sales and Expense Components

The following is a description of the primary components of our net sales and expenses:

Net sales. We derive our net sales from the sale of our products, less discounts and returns. Net sales include the shipping and handling fees paid for by our customers. Most of our sales are generated by our direct sales force and are shipped and billed to hospitals or clinics throughout the world. In countries where we do not have a direct sales force, sales are primarily generated by shipments to distributors who, in turn, sell to hospitals and clinics. In those cases where our products are held on consignment at a hospital or clinic, we generate sales at the time the product is used in surgery rather than at shipment.

Cost of sales. We manufacture nearly all of the products that we sell. Our cost of sales consists primarily of manufacturing personnel, raw materials and components, depreciation of property and equipment, and other allocated manufacturing overhead, as well as freight expense we pay to ship products to customers.

Sales and marketing. Our sales and marketing expense consists primarily of salaries, commissions, stock based compensation, travel and entertainment, attendance at medical society meetings, training programs, advertising and product promotions, direct mail, and other marketing costs.

General and administrative. General and administrative expense consists primarily of executive, finance and human resource expense, stock based compensation, legal and accounting fees, information technology expense, intangible amortization expense, and insurance expense.

41

Research and development. Research and development expense includes costs associated with the design, development, testing, enhancement, and regulatory approval of our products, principally salaries, laboratory testing, and supply costs. It also includes costs associated with design and execution of clinical studies, regulatory submissions and costs to register, maintain, and defend our intellectual property, and royalty payments associated with licensed and acquired intellectual property.

Restructuring. Restructuring expense includes costs directly associated with distribution agreement termination expenses, severance and retention costs for terminated employees, factory relocation costs, and other expenses associated with restructuring our operations.

Other income (expense). Other income (expense) primarily includes interest income and expense, investment impairment charges, foreign currency gains (losses), and other miscellaneous gains (losses).

Income tax expense. We are subject to federal and state income taxes for earnings generated in the United States, which include operating losses in certain foreign jurisdictions for certain years depending on tax elections made, and foreign taxes on earnings of our wholly-owned Canadian, German, and Italian subsidiaries. Our consolidated tax expense is affected by the mix of our taxable income (loss) in the United States and foreign subsidiaries, permanent items, discrete items, unrecognized tax benefits, and amortization of goodwill for U.S tax reporting purposes.

Results of Operations

Comparison of the year ended December 31, 2013, to the year ended December 31, 2012

The following tables set forth, for the periods indicated, our results of operations and the change between the specified periods expressed as a percent increase or decrease:

	2013		2012		$ Change		Percent change
	($ in thousands)
Net sales	$	64,549	$	56,735	$	7,814		14	%
Net sales by geography:
Americas	$	42,657	$	38,273	$	4,384		11	%
International		21,892		18,462		3,430		19	%
Total	$	64,549	$	56,735	$	7,814		14	%

Net sales. Net sales increased 14% to $64.5 million in 2013 from $56.7 million in 2012. Sales from newly acquired product lines contributed 2.7% to the sales growth.

Net sales increases of $7.8 million in 2013 were primarily driven by increased sales in biologic vascular patches of $2.6 million, valvulotomes of $1.2 million, catheters of $1.3 million, Dacron grafts of $0.6 million, and vessel closure systems of $0.6 million. In addition, sales of newly acquired powered phlebectomy systems were $1.3 million. This sales growth was partially offset by decreased sales of radiopaque tape and non-occlusive modeling catheters. The primary drivers of increased sales were higher average selling prices across all product lines, increases in unit sales, and increased sales of Dacron grafts previously prohibited in certain European countries. Our biologic vascular patches comprised 12% of our revenues in 2013 compared to 9% in 2012 and 5% in 2011.

Direct-to-hospital net sales were 92% of net sales in 2013 compared to 94% in 2012 and was primarily driven by sales of powered phlebectomy systems and vessel closure systems to our China distributors of $1.0 million.

42

Net sales by geography. Net sales in the Americas increased $4.4 million to $42.7 million in 2013. The increase was largely the result of higher average selling prices across nearly all product lines, as well as increased sales of biologic vascular patches, powered phlebectomy systems, vascular closure systems, catheters, and shunts. Net sales increases in the Americas were also due to higher Canadian and export sales. These increases were partially offset by a decrease in radiopaque tape of $0.6 million and non-occlusive modeling catheters of $0.1 million. International net sales increased $3.4 million to $21.9 million in 2013. The increase was primarily driven by higher sales of biologic vascular patches of $1.3 million, catheters of $0.9 million, Dacron grafts, valvulotomes, and shunts.

Gross profit	$	45,115		$	40,868		$	4,247		10	%
Gross margin		69.9	%		72.0	%		*		(2.1	%)

* Not applicable

Gross profit. Gross profit increased $4.2 million to $45.1 million in 2013 from $40.9 million in 2012, while our gross margin decreased 2.1% to 69.9%. The gross margin decrease was largely driven by unfavorable geographic mix, sales to lower margin export markets, increased sales of our lower margin biologic vascular patch, manufacturing start-up costs associated with our biologic vascular patch, and costs associated with newly acquired Clinical Instruments facility. These decreases were partially offset by higher non-recurring Dacron graft inventory write-offs in 2012, higher average selling prices across all product lines, and improved manufacturing efficiencies. The gross profit increase was a result of higher sales.

In November 2012, we acquired the manufacturing and distribution rights of the XenoSure biologic vascular patch, and we expect that the related manufacturing transfer will continue to negatively affect our gross margin in 2014. We expect to realize efficiencies which may improve gross margins on our XenoSure biologic vascular patch beginning in 2015. In addition, we closed our Clinical Instruments facility in March 2014 and are transitioning production to our Burlington facility which we believe will help improve the gross margin beginning in the second quarter of 2014.

Sales and marketing. Sales and marketing expenses were $22.1 million in 2013 compared to $20.8 million in 2012, an increase of 6%. As a percentage of net sales, sales and marketing expenses were 34% in 2013, down 3% from the prior year. Selling expenses increased $1.7 million while marketing expenses decreased by $0.4 million. The increase in selling expenses was primarily driven by increased sales personnel compensation of $1.1 million, partially due to additional sales personnel in Switzerland and Canada, and $0.5 million of additional sales meetings and travel costs. Marketing expense decreases were largely driven by a $0.3 million reduction in advertising costs and $0.1 million reduction in trade show expenses, which were partially offset by an increase in compensation expense of $0.2 million. At December 31, 2013, we employed 85 sales representatives worldwide, compared to 81 in the prior year period. We plan to increase the size of our sales force in 2014, related partly to the hiring of additional sales representatives in Australia and Norway, and we expect that selling and marketing expenses will increase commensurately.

43

General and administrative. General and administrative expenses increased 15% to $12.6 million in 2013 from $11.0 million in 2012. The increase was largely the result of expenses associated with our newly formed subsidiary in Canada, increased compensation costs of $0.7 million, increased professional services costs of $0.6 million, and increased intangibles amortization of $0.3 million, which were partially offset by decreased employee termination and bad debt expenses. As a percentage of net sales, general and administrative expenses were 19% in both 2013 and 2012. We expect general and administrative expenses to increase in 2014 primarily due to our new subsidiary in Australia.

Research and development. Research and development expenses increased 3% to $5.2 million in 2013 from $5.1 million in 2012. As a percentage of net sales, research and development expenses decreased to 8% in 2013 from 9% in 2012. Product development expenses decreased $0.2 million primarily due to lower product testing costs of $0.3 million which was partially offset by increased product engineer compensation. Clinical and regulatory expenses increased $0.3 million, primarily due to an increase in compensation expenses and regulatory submissions for new products in geographies such as China and Australia. Process engineering expenses increased $0.1 million primarily due to the addition of the TRIVEX product line. Royalty expenses were flat.

Medical device excise tax. Commencing in 2013, we were subject to a medical device excise tax equal to 2.3% of sales within the United States. The medical device excise tax was $0.6 million in 2013.

Restructuring. We did not incur restructuring charges in 2013 and 2012. In February 2014, we committed to a plan intended to improve operational efficiencies, which includes a reduction in force of approximately 10% of our workforce and other cost-cutting measures. The plan was implemented during the first quarter of 2014. We estimate that termination costs will be $0.2 million to $0.4 million. We expect to record the majority of these charges in 2014.

Gain on divestitures. In 2012, we recognized a gain on divestitures of $0.2 million resulting from payments on a promissory note related to the divestiture of our TAArget and UniFit stent graft product lines to Duke Vascular, Inc. in 2011.

Other income (expense). Foreign exchange losses for 2013 were $0.2 million compared to $0.3 million for 2012 and were generally flat other than a one-time exchange loss of $0.2 million as a result of a cumulative translation adjustment recorded at our Biomateriali subsidiary upon the liquidation and dissolution of that legal entity in 2012. Net interest income and other income (expense) decreased by approximately $80,000 primarily related to interest earned in 2012 from the stent graft divestiture promissory note.

Income tax expense. We recorded a provision for taxes of $1.1 million on pre-tax income of $4.3 million in 2013 compared to $1.4 million on pre-tax income of $4.0 million in 2012. The 2013 provision was comprised of Federal tax in the United States of $2.5 million, state taxes of $0.1 million and a net foreign tax benefit of $1.4 million. The 2012 provision was comprised of Federal tax in the United States of $1.4 million, state taxes of $0.1 million and a net foreign benefit of $0.1 million. Our effective tax rate differed from the U.S. statutory tax rate in 2013 principally due to research and development tax credits, release of uncertain tax position reserves due to the expiration of the statute of limitations, effect of foreign taxes, manufacturing deductions, other permanent differences, stock-based compensation, Subpart-F income and state taxes. While it is often difficult to predict the final outcome or timing of the resolution of any particular tax matter, we believe that our tax reserves reflect the probable outcome of known contingencies.

We have assessed the need for a valuation allowance against our deferred tax assets and concluded that as of December 31, 2013, we will continue to carry a valuation allowance against $1.0 million of deferred tax assets, principally foreign net operating loss carry-forwards, which based on the weight of available evidence, we believe it is more likely than not that such assets will not be realized.

We expect that our effective tax rate in 2014 will be higher than our effective tax rate in 2013. We will not be able to generate Federal research and development tax credits in 2014 until and if legislation is enacted.

Comparison of the year ended December 31, 2012, to the year ended December 31, 2011

The following tables set forth, for the periods indicated, our results of operations and the change between the specified periods expressed as a percent increase or decrease:

	2012		2011		$ Change			Percent change
	($ in thousands)
Net sales	$	56,735	$	57,685	$	(950	)		(2	%)
Net sales by geography:
Americas	$	38,273	$	36,958	$	1,315			4	%
International		18,462		20,727		(2,265	)		(11	%)
Total	$	56,735	$	57,685	$	(950	)		(2	%)

Net sales. Net sales decreased 2% to $56.7 million in 2012 from $57.7 million in 2011. Divestitures, primarily of the TAArget and UniFit stent graft product lines as well as the termination of the Endologix aortic stent graft distribution agreement, resulted in a decrease in sales of 8% from the prior year. Changes in foreign currency exchange rates reduced year over year sales by 2%.

Net sales decreases of $1.0 million in 2012 were primarily driven by the 2011 divestiture of our stent graft product lines which accounted for $4.0 million of sales during 2011, a $0.6 million decrease in polyester graft sales, and a weakening of the Euro, which negatively impacted sales by $1.3 million. These decreases were partially offset by higher average selling prices across nearly all product lines, increased sales of biologic patches of $2.0 million, increased sales of radiopaque tape of $0.6 million and increased sales of catheters of $0.5 million, which was partially driven by selected pricing discounts in new geographies.

Direct-to-hospital net sales were 94% of net sales in 2012, compared to 93% in 2011.

Net sales by geography. Net sales in the Americas increased $1.3 million to $38.3 million in 2012. The increase was largely the result of higher average selling prices across nearly all product lines, as well as increased sales of biologic patches, radiopaque tape of $0.5 million, catheters of $0.3 million, and vascular closure systems of $0.2 million. These increases were partially offset by the divestiture of our stent graft product lines which accounted for $0.5 million in 2011. International net sales decreased $2.3 million to $18.5 million in 2012. The decrease was primarily driven by the divestiture of our stent graft product lines which accounted for $3.5 million in 2011, a decrease in polyester graft sales, and the negative effects of foreign currency exchange rates, which were partially offset by increased sales of biologic patches of $1.1 million and catheters of $0.3 million. Biologic patches became available for sale in Europe in July 2011.

In April 2012, the regulatory agencies in the United Kingdom and France issued Prohibition Notices which prohibited us from selling our AlboGraft polyester grafts in those countries until further notice. In July 2012, the regulatory agencies substantially rescinded the Prohibition Notices allowing the products to return to market. Sales of AlboGraft in France and the United Kingdom were $0.5 million in 2012 compared to $1.0 million in 2011.

Gross profit. Gross profit increased $0.6 million to $40.9 million in 2012 from $40.2 million in 2011, while our gross margin increased 2.3% to 72.0%. The gross margin increase was largely the result of a reduction in costs related to the closure of our factory in Brindisi, Italy in March 2011, a reduction in costs associated with the

45

2011 manufacturing start-up and transition activities related to the AlboGraft and Lifespan product lines, increased selling prices across most of our product lines, and favorable product and geographic mix driven largely by our exit from stent grafts. The gross margin increase was partially offset by manufacturing inefficiencies as well as increased sales of XenoSure. The gross profit increase was largely the result of the increase in the gross margin, which was partially offset by our exit from the stent graft product lines, which generated $4.0 million of revenue in 2011.

Sales and marketing. Sales and marketing expenses were $20.8 million in 2012 compared to $19.4 million in 2011. As a percentage of net sales, sales and marketing expenses were 37% in 2012, up 3% from the prior year. Selling expenses increased $1.0 million while marketing expenses increased by $0.4 million. The increase in selling expenses was primarily driven by increased sales personnel compensation of $0.8 million and $0.2 million of additional sales meetings and travel costs. These increases were partially offset by $0.2 million of 2011 transition services related to the LifeSpan acquisition and the buy-out of our former Spanish distributor. Marketing expense increases were largely driven by $0.3 million of additional advertising costs. Changes in foreign currency exchange rates reduced 2012 expenses by $0.6 million compared to the prior year period. At December 31, 2012, we employed 81 sales representatives worldwide, compared to 78 in the prior year period.

General and administrative. General and administrative expenses decreased 2% to $11.0 million in 2012 from $11.2 million in 2011. The decrease was largely driven by a decrease in compensation costs of $0.3 million, the closure of our Biomateriali facility in March 2011, which incurred general and administrative costs of $0.1 million in the prior year period, and by changes in foreign currency exchange rates of $0.3 million. These decreases were partially offset by the settlement of an employee matter of $0.1 million and bad debt expense relating to certain European markets of $0.1 million. As a percentage of net sales, general and administrative expenses were 19% in both 2012 and 2011.

Research and development. Research and development expenses increased 15% to $5.1 million in 2012 from $4.4 million in 2011. As a percentage of net sales, research and development expenses increased to 9% in 2012 from 8% in 2011. Product development expenses increased $1.0 million primarily due to increased product engineer compensation and additional testing and sample costs. Clinical and regulatory expenses increased $0.1 million, primarily due to an increase in compensation expenses. Process engineering expenses decreased $0.2 million. Royalty expenses decreased $0.2 million, primarily due to our exit from our stent graft product lines.

Restructuring. We did not incur restructuring charges in 2012 compared to $2.2 million of restructuring charges in the prior year. In 2011, we closed our Biomateriali manufacturing facility in Brindisi, Italy and transitioned production to our existing facility in Burlington, Massachusetts. In 2011, we also closed our Lifespan manufacturing facility in Laguna Hills, California and transitioned production to Burlington. Finally, we terminated our Spanish and Danish distribution agreements and reorganized our European administrative and sales personnel as a result of our exit from the stent graft business in 2011.

46

Gain on divestitures. In 2012, we recognized a gain on divestitures of $0.2 million resulting from payments on a promissory note related to the divestiture of our TAArget and UniFit stent graft product lines to Duke Vascular, Inc. in 2011. In July 2011, we terminated our Endologix distribution agreement for $1.3 million and recognized a gain of $0.7 million.

Impairment charges. We did not incur impairment charges in 2012. We incurred $0.1 million of impairment charges in 2011 related to patents deemed to have no value based on future expected economic benefits.

Other income (expense). Foreign exchange losses for 2012 were $0.3 million compared to foreign exchange gains for 2011 of $51,000. Foreign exchange gains were due to the comparative strengthening of the U.S. dollar versus the euro during the year. Net interest income and other income (expense) increased by approximately $67,000 primarily due to the interest earned from the promissory note related to our stent graft divestiture in 2011.

Income tax expense. We recorded a provision for taxes of $1.4 million on pre-tax income of $4.0 million in 2012 compared to $1.6 million on pre-tax income of $3.8 million in 2011. The 2012 provision was comprised of Federal tax in the United States of $1.4 million, state taxes of $0.1 million and a net foreign tax benefit of $0.1 million. The 2011 provision was comprised of Federal tax in the United States of $1.1 million, taxes in certain foreign subsidiaries that are profitable of $0.4 million and state taxes of $0.1 million. Our effective tax rate differed from the U.S. statutory tax rate in 2012 principally due to permanent items, changes in our valuation allowances, specific manufacturing deductions, state taxes, and release of uncertain tax position reserves. While it is often difficult to predict the final outcome or timing of the resolution of any particular tax matter, we believe that our tax reserves reflect the probable outcome of known contingencies.

Liquidity and Capital Resources

At December 31, 2013, our cash, cash equivalents and marketable securities were $14.7 million compared to $16.4 million at December 31, 2012. Our cash and cash equivalents are highly liquid investments with maturities of 90 days or less at the date of purchase and consist of money market funds, and are stated at cost, which approximates fair value. We did not hold any marketable securities nor any mortgage asset-backed or auction-rate securities in our investment portfolio as of December 31, 2013. All of our cash held outside of the United States is available for corporate use.

Operating and Capital Expenditure Requirements

We require cash to pay our operating expenses, make capital expenditures, fund acquisitions, and pay our long-term liabilities. Since our inception, we have funded our operations through private and public placements of equity securities, short-term borrowings, and funds generated from our operations.

For the year ended December 31, 2013, we recognized operating income of $4.5 million. For the year ended December 31, 2012, we recognized operating income of $4.2 million. We expect to fund any increased costs and expenditures from our existing cash and cash equivalents, though our future capital requirements depend on numerous factors. These factors include, but are not limited to, the following:

• the revenues generated by sales of our products;

• payments associated with potential future quarterly cash dividends to our common stockholders;

• future payments associated with the acquisitions of InaVein and Clinical Instruments;

• payments associated with U.S income and other taxes, such as the medical device tax;

47

• the costs associated with expanding our manufacturing, marketing, sales, and distribution efforts;

• the costs associated with our initiatives to sell direct-to-hospital in new countries;

• the costs of obtaining and maintaining FDA and other regulatory clearances of our existing and future products; and

• the number, timing, and nature of acquisitions and other strategic transactions.

Our cash balances may decrease as we continue to use cash to fund our operations, make acquisitions, make payments under our quarterly dividend program, and make deferred payments related to prior acquisitions. We believe that our cash, cash equivalents, investments and the interest we earn on these balances will be sufficient to meet our anticipated cash requirements for at least the next twelve months. If these sources of cash are insufficient to satisfy our liquidity requirements beyond the next twelve months, we may seek to sell additional equity or debt securities or borrow funds from, or establish a revolving credit facility with a financial institution. The sale of additional equity and debt securities may result in dilution to our stockholders. If we raise additional funds through the issuance of debt securities, such securities could have rights senior to those of our common stock and could contain covenants that would restrict our operations and possibly our ability to pay dividends. We may require additional capital beyond our currently forecasted amounts. Any such required additional capital may not be available on reasonable terms, if at all.

Italian loan and grant

As part of the purchase of Biomateriali S.r.l, we assumed a loan from the Italian government under a program that provided funding to certain businesses in Italy through a combination of grants and loans if certain requirements are met. The loan was stated to be payable in ten annual payments through 2018 of principal and interest at an interest rate of 0.74%. The present value of the loan was recorded as of the date the proceeds were received using our incremental borrowing rate. Interest was being imputed on the loan and the amortization was recorded as interest expense. The Italian government informed us the loan and grant became due in full as a result of the Biomateriali S.r.l plant closure. As a result, in December 2011, we incurred approximately $0.1 million of restructuring charges related to additional interest and penalties charges, and we made the final payment to the Italian government of $0.5 million.

Cash Flows

	Year ended December 31,						Net Change
	2013			2012
Cash and cash equivalents	$	14,711		$	16,448		$	(1,737	)
Cash flows provided by (used in):
Operating activities	$	5,388		$	4,722		$	666
Investing activities		(6,188	)		(5,198	)		(990	)
Financing activities		(961	)		(3,157	)		2,196

Operating activities. Net cash provided by operating activities was $5.4 million in 2013 and consisted of $3.2 million in net income, adjusted for non-cash items of $5.0 million (including depreciation and amortization of $2.8 million, stock-based compensation of $1.3 million, and provision for inventory write-offs of $0.5 million), and net cash used by changes in working capital of $2.8 million. The net cash used by changes in working capital was principally the result of increased receivables and inventories of $3.4 million and partially offset by increased accounts payables.

Net cash provided by operating activities was $4.7 million in 2012 and consisted of $2.6 million in net income, adjusted for non-cash items of $4.9 million (including depreciation and amortization of $2.2 million, stock-based compensation of $1.2 million, and provision for inventory write-offs of $0.9 million), and net cash used by changes in working capital of $2.7 million. The net cash used by changes in working capital was principally the result of increased inventories of $3.7 million and partially offset by increased accounts payables.

48

Investing activities. Net cash used in investing activities was $6.2 million in 2013. This was primarily driven by acquisition related payments of $3.3 million, of which payments to InaVein and Clinical Instruments were $3.0 million, and the purchase of property and equipment of $2.7 million of which $0.9 million related to facility build-out and manufacturing equipment associated with our biologic vascular patch.

Net cash used in investing activities was $5.2 million in 2012. This was due to the $4.4 million of acquisition related payments, primarily related to the XenoSure biologic patch acquisition, certain distributor buyouts, and the purchase of new property and equipment of $1.2 million. These cash uses were partially offset by a $0.5 million repayment of a promissory note from Duke Vascular related to our stent graft divestiture in 2011.

Financing activities. Net cash used in financing activities was $1.0 million in 2013, driven primarily by payment of common stock dividends of $1.8 million and the purchase of $0.4 million of treasury stock to cover minimum withholding taxes of restricted stock unit vestings, which were partially offset by proceeds from stock option exercises of $1.2 million.

Net cash used in financing activities was $3.2 million in 2012. This was primarily due to the purchase of $1.7 million of treasury stock under our stock repurchase plan, payment of common stock dividends of $1.5 million, and the purchase of $0.3 million of treasury stock to cover minimum withholding taxes of restricted stock unit vestings, and was partially offset by $0.4 million received from the exercise of stock options.

Dividends. On February 24, 2011, our Board of Directors approved a policy for the payment of quarterly cash dividends on our common stock. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by our Board of Directors on a quarterly basis. The dividend activity for the periods presented is as follows:

Record Date	Payment Date	Per Share Amount	Dividend Payment
			(in thousands)
Fiscal Year 2013
March 20, 2013	April 3, 2013	$0.030	$457
May 22, 2013	June 5, 2013	$0.030	$457
August 21, 2013	September 4, 2013	$0.030	$460
November 20, 2013	December 4, 2013	$0.030	$464
Fiscal Year 2012
March 20, 2012	April 3, 2012	$0.025	$381
May 18, 2012	June 4, 2012	$0.025	$379
August 17, 2012	August 31, 2012	$0.025	$380
November 20, 2012	December 4, 2012	$0.025	$378

On February 20, 2014, our Board of Directors approved a quarterly cash dividend on our common stock of $0.035 per share payable on April 3, 2014, to stockholders of record at the close of business on March 20, 2014, which will total approximately $0.5 million.

Contractual obligations. Our principal contractual obligations consist of operating leases and inventory purchase commitments. The following table summarizes our commitments to settle contractual obligations as of December 31, 2013:

Contractual obligations	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
	(in thousands)
Operating leases	$	8,758	$	1,159	$	2,033	$	1,491	$	4,075
Purchase commitments for inventory		4,411		4,125		286		—		—
Total contractual obligations	$	13,169	$	5,284	$	2,319	$	1,491	$	4,075

49

The commitments under our operating leases consist primarily of lease payments for our Burlington, Massachusetts, corporate headquarters and manufacturing facility, expiring in 2023; our Toronto, Ontario, Canada office, expiring in 2018; our Sulzbach, Germany office, expiring in 2016; our Tokyo, Japan office, expiring in 2016; our Milan, Italy office, expiring in 2016; our Madrid, Spain office, expiring in 2014; and our Melbourne, Australia office, expiring in 2017. They also include automobile and equipment leases.

The purchase commitments for inventory are to be used in operations over the normal course of business and do not represent excess commitments or loss contracts.

Critical Accounting Policies and Estimates

We have adopted various accounting policies to prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles (GAAP). Our most significant accounting policies are described in note 1 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. The preparation of our consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, and income taxes are reviewed on an ongoing basis and updated as appropriate. Actual results could differ from those estimates.

Certain of our more critical accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of uncertainty. These judgments are based on our historical experience, terms of existing contracts, and observance of trends in the industry, as appropriate. Different, reasonable estimates could have been used in the current period. Additionally, changes in accounting estimates are reasonably likely to occur from period to period. Both of these factors could have a material impact on the presentation of our financial condition, changes in financial condition, or results of operations.

We believe that the following financial estimates and related accounting policies are both important to the portrayal of our financial condition and results of operations and require subjective or complex judgments. Further, we believe that the items discussed below are properly recorded in our consolidated financial statements for all periods presented. Management has discussed the development, selection and disclosure of our most critical financial estimates with the audit committee of our board of directors and our independent registered public accounting firm. The judgments about those financial estimates are based on information available as of the date of our consolidated financial statements. Those financial estimates and related policies include:

Revenue Recognition

Our revenue is derived primarily from the sale of disposable or implantable devices used during vascular surgery. We sell primarily directly to hospitals and to a lesser extent to distributors, as described below, and, during the periods presented in our consolidated financial statements, entered into consigned inventory arrangements with either hospitals or distributors on a limited basis.

We recognize revenue when four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. We generally use customer purchase orders or contracts to determine the existence of an arrangement. Sales transactions are based on prices that are determinable at the time that the customer’s purchase order is accepted by us. In order to determine whether collection is reasonably assured, we assess a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection is not reasonably assured, we would defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment. We provide for product returns at the time revenue is recognized based on our historical return product history. Based on these policies, we recognize revenue, net of allowances for returns and discounts, as products are shipped, based on shipping

50

point terms, or at the time consigned inventory is consumed at which time title passes to customers. We recognize revenue net of allowances for returns and discounts, at the time of shipment of our products to our distributors.

Accounts Receivable

Our accounts receivable are with customers based in the United States and internationally. Accounts receivable generally are due within 30 to 90 days of invoice and are stated at amounts due from customers, net of an allowance for doubtful accounts and sales returns, other than in certain European markets where longer payment terms are customary and may range from 90 to 240 days. We perform ongoing credit evaluations of the financial condition of our customers and adjust credit limits based upon payment history and the current creditworthiness of the customers, as determined by a review of their current credit information. We continuously monitor aging reports, collections, and payments from customers, and maintain a provision for estimated credit losses based upon historical experience and any specific customer collection issues we identify.

We closely monitor outstanding receivables for potential collection risks, including those that may arise from economic conditions, in both the U.S. and international economies. Our European sales to government-owned or supported customers such as hospitals, distributors and agents, in Southern Europe, specifically Italy and Spain may be subject to significant payment delays due to government austerity measures impacting funding and payment practices. As of December 31, 2013 our receivables in Italy and Spain totaled $1.2 million and $0.5 million, respectively. Receivables balances with certain publicly-owned hospitals and government supported customers in these countries can accumulate over a period of time and then subsequently be settled as large lump sum payments. While we believe our allowance for doubtful accounts in these countries is adequate as of December 31, 2013, if significant changes were to occur in the payment practices of these European governments or if government funding becomes unavailable, we may not be able to collect on receivables due to us from these customers and our write offs of uncollectible amounts may increase.

We write off accounts receivable when they become uncollectible. While such credit losses have historically been within our expectations and allowances, we cannot guarantee the same credit loss rates will be experienced in the future. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for doubtful accounts on a monthly basis and all past due balances are reviewed individually for collectability. The provision for the allowance for doubtful accounts is recorded in general and administrative expenses.

Inventory

Inventory consists of finished products, work-in-process, and raw materials. We value inventory at the lower of cost or market value. Cost includes materials, labor, and manufacturing overhead and is determined using the first-in, first-out (FIFO) method. On a quarterly basis, we review inventory quantities on hand and analyze the provision for excess and obsolete inventory based primarily on product expiration dating and our estimated sales forecast, which is based on sales history and anticipated future demand. Our estimates of future product demand may not be accurate, and we may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated changes in demand could have a significant impact on the value of our inventory and results of operations.

Stock-based Compensation

We recognize, as expense, the estimated fair value of stock options to employees which is determined using the Black-Scholes option pricing model. We have elected to recognize the compensation cost of all share-based awards on a straight-line basis over the vesting period of the award. In periods that we grant stock options, fair value assumptions are based on volatility, interest, dividend yield, and expected term over which the stock options will be outstanding. The computation of expected volatility is based on the historical volatility of the company’s stock. The interest rate for periods within the contractual life of the award is based on the

51

U.S. Treasury risk-free interest rate in effect at the time of grant. Historical data on exercise patterns is the basis for estimating the expected life of an option. The expected annual dividend rate was calculated by dividing our annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date.

We also issue restricted stock units (RSUs) as an additional form of equity compensation to our employees, officers, and directors, pursuant to our stockholder-approved 2006 Plan. RSUs entitle the grantee to an issuance of stock at no cost and generally vest over a period of time determined by our Board of Directors at the time of grant based upon the continued service to the company. The fair market value of the award is determined based on the number of RSUs granted and the market value of our common stock on the grant date and is amortized to expense over the period of vesting. Unvested RSUs are forfeited and canceled as of the date that employment or service to the company terminates. RSUs are settled in shares of our common stock upon vesting. We may repurchase common stock upon our employees’ vesting in RSUs in order to cover any minimum tax withholding liability as a result of the RSUs having vested.

Share-based compensation charges are recorded net of the estimated forfeitures based upon historical rates and will be adjusted in future periods to reflect the results of actual forfeitures and vesting. Share-based compensation charges are recorded across the consolidated statement of operations based upon the grantee’s primary function.

As disclosed more fully in the notes to our consolidated financial statements, we recorded expense of approximately $1.3 million in connection with share-based payment awards for the year ended December 31, 2013. The future expense of non-vested share-based awards of approximately $2.6 million is to be recognized over a weighted-average period of 3.4 years. During 2013, we granted stock options at a weighted average fair value of $3.01 and restricted stock units with weighted average fair value of $6.67.

Valuation of Goodwill, and Other Intangibles

Goodwill represents the amount of consideration paid in connection with business acquisitions in excess of the fair value of assets acquired and liabilities assumed. Goodwill is evaluated for impairment annually or more frequently if indicators of impairment are present or changes in circumstances suggest that an impairment may exist. We evaluate the December 31 balance of the carrying value of goodwill based on a single reporting unit annually. We perform an assessment of qualitative factors to determine if it is “more likely than not” that the fair value of our reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The “more likely than not” threshold is defined as having a likelihood of more than 50 percent. If required, the next step of the goodwill impairment test is to determine the fair value of the reporting unit. The implied fair value of goodwill is determined on the same basis as the amount of goodwill recognized in connection with a business combination. Specifically, the fair value of a reporting unit is allocated to all of the assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination as of the date of the impairment review and as if the fair value of the reporting unit was the price paid to acquire the reporting unit. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Goodwill was $15.0 million and $13.7 million as of December 31, 2013 and 2012, respectively. Our annual impairment testing indicated no significant risk of impairment based upon changes in value that are reasonably likely to occur. However, changes in these estimates and assumptions could materially affect the estimated fair value of our reporting unit.

Other intangible assets consist primarily of purchased developed technology, patents, customer relationships, and trademarks and are amortized over their estimated useful lives, ranging from 1 to 13 years. We review intangible assets quarterly to determine if any adverse conditions exist for a change in circumstances has occurred that would indicate impairment. Conditions that may indicate impairment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of the asset, a change in the operating cash flows associated with the asset, or adverse action or assessment by a regulator. If an

52

impairment indicator exists we test the intangible asset for recoverability. If the carrying value of the intangible asset exceeds the undiscounted cash flows expected to result from the use and eventual disposition of the intangible asset, we will write the carrying value down to the fair value in the period identified. We generally calculate fair value of our intangible assets as the present value of estimated future cash flows we expect to generate from the asset using a risk-adjusted discount rate. In determining our estimated future cash flows associated with our intangible assets, we use estimates and assumptions about future revenue contributions, cost structures, and remaining useful lives of the asset. These estimates and assumptions require significant judgment and actual results may differ from assumed or estimated amounts. Other intangible assets, net of accumulated amortization, were $6.1 million as of December 31, 2013, and $5.2 million as of December 31, 2012. We recognized impairment charges on our intangible assets of $0.1 million in 2011.

Contingencies

In the normal course of business, we are subject to proceedings, lawsuits, and other claims and assessments for matters related to, among other things, patent infringement, business acquisitions, employment, product liability and product recalls. We assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. We record charges for the costs we anticipate incurring in connection with litigation and claims against us when we determine a loss is probable and we can reasonably estimate these costs. During the years ended December 31, 2013, 2012, and 2011, we were not subject to any material litigation, claims or assessments.

Restructuring

We record restructuring charges incurred in connection with consolidation or relocation of operations, exited business lines, reductions in force, or distributor terminations. These restructuring charges, which reflect our commitment to a termination or exit plan that will begin within twelve months, are based on estimates of the expected costs associated with site closure, legal matters, contract terminations, severance payments, or other costs directly related to the restructuring. If the actual cost incurred exceeds the estimated cost, an additional charge to earnings will result. If the actual cost is less than the estimated cost, a credit to earnings will be recognized.

Income Taxes

As part of the process of preparing our consolidated financial statements we are required to determine our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax expense together with assessing temporary differences resulting from recognition of items for income tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from taxable income during the carryback period or in the future; and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance in a period, we must reflect this increase as an expense within the tax provision in the statement of operations. We do not provide for income taxes on undistributed earnings of foreign subsidiaries, as our current intention is to permanently reinvest these earnings.

We recognize, measure, present and disclose in our financial statements, uncertain tax positions that we have taken or expect to take on a tax return. We operate in multiple taxing jurisdictions, both within the United States and outside of the United States and may be subject to audits from various tax authorities regarding transfer pricing, the deductibility of certain expenses, intercompany transactions, and other matters. Within specific countries, we may be subject to audit by various tax authorities operating within the country and may be subject to different statutes of limitation expiration dates. Management’s judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any

53

valuation allowance recorded against our net deferred tax assets. We will continue to monitor the realizability of our deferred tax assets and adjust the valuation allowance accordingly. We have recorded a valuation allowance on our net deferred tax assets of $1.0 million and $3.1 million as of December 31, 2013 and 2012, respectively.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (FASB) issued new guidance which requires disclosure of changes in accumulated other comprehensive income balances by component and significant reclassification adjustments from accumulated other comprehensive income in a single note or on the face of the financial statements. This guidance became effective January 1, 2013. The adoption of this standard, which is related to disclosure only, did not have an impact on our results of operations or financial position.

In July 2013, the FASB issued guidance to address the diversity in practice related to the financial statement presentation of unrecognized tax benefits as either a reduction of a deferred tax asset or a liability when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2013. We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are not materially exposed to any financing, liquidity, market, or credit risk that could arise if we had engaged in these relationships.

Evaluation of Disclosure Controls and Procedures

Based on their evaluation as of December 31, 2013, our Chief Executive Officer and Chief Financial Officer, with the participation of management, have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) were effective at reasonable assurance levels.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.

Management assessed the effectiveness of our internal controls over financial reporting as of December 31, 2013. Management based its assessment on criteria established in the Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 Framework). Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies, and our overall control environment.

Based on this assessment under the criteria set forth in the Internal Control—Integrated Framework, management has concluded that our internal control over financial reporting was effective as of December 31, 2013.

Pursuant to Item 308 of Regulation S-K, this management’s report on internal control over financing reporting shall not be deemed filed for purposes of Section 18 of the Exchange Act or otherwise subject to the liabilities of that section.

Changes in Internal Control over Financial Reporting

There was no change in the our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2013, that has materially affected, or is reasonably likely to materially affect our internal control over financial reporting.

Inherent Limitations of Internal Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of LeMaitre Vascular, Inc.

We have audited the accompanying consolidated balance sheets of LeMaitre Vascular, Inc. (the Company) as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income, statements of stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of LeMaitre Vascular, Inc. at December 31, 2013 and 2012, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

Notes to Consolidated Financial Statements

December 31, 2013

1. Significant Accounting Policies and Related Matters

Description of Business

Unless the context requires otherwise, references to LeMaitre Vascular, we, our, and us refer to LeMaitre Vascular, Inc. and our subsidiaries. We develop, manufacture, and market medical devices and implants used primarily in the field of vascular surgery. We operate in a single segment in which our principal product lines include the following: valvulotomes, balloon catheters, carotid shunts, biologic patches, radiopaque marking tape, anastomotic clips, remote endarterectomy devices, laparoscopic cholecystectomy devices, vascular grafts, and powered phlebectomy. Our offices are located in Burlington, Massachusetts; Mississauga, Canada; Sulzbach, Germany; Milan, Italy; Madrid, Spain; Melbourne, Australia and Tokyo, Japan.

Consolidation and Basis of Presentation

Our consolidated financial statements include the accounts of LeMaitre Vascular and the accounts of our wholly-owned subsidiaries, LeMaitre Vascular GmbH, LeMaitre Vascular GK, Vascutech Acquisition LLC, LeMaitre Acquisition LLC, LeMaitre Vascular SAS, LeMaitre Vascular S.r.l., LeMaitre Vascular Spain SL, LeMaitre Vascular Switzerland GmbH, LeMaitre Vascular ULC, LeMaitre Vascular AS, and LeMaitre Vascular Pty Ltd. All significant intercompany accounts and transactions have been eliminated in consolidation.

Foreign Currency Translation

Balance sheet accounts of foreign subsidiaries are translated into U.S. dollars at year-end exchange rates. Operating accounts are translated at average exchange rates for each year. Net translation gains or losses are adjusted directly to a separate component of other comprehensive income (loss) within stockholders’ equity. Foreign exchange transaction gains (losses), substantially all of which relate to intercompany activity between us and our foreign subsidiaries, are included in other income (expense) in the accompanying consolidated statements of operations.

Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to bad debts, inventories, intangible assets, sales returns and discounts, and income taxes are reviewed on an ongoing basis and updated as appropriate. Actual results could differ from those estimates.

Revenue Recognition

Our revenue is derived primarily from the sale of disposable or implantable devices used during vascular surgery. We sell primarily directly to hospitals and to a lesser extent to distributors, as described below, and, during the periods presented in our consolidated financial statements, entered into consigned inventory arrangements with either hospitals or distributors on a limited basis.

We recognize revenue when four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed or determinable; and (4) collectability is reasonably assured. We assess whether the fee is fixed or determinable based on the terms of the agreement associated with the transaction. Sales transactions are based on prices that are determinable at the time the customer’s purchase order is accepted by us. Orders that are not accompanied with a purchase order are either confirmed in writing or verbally with the customer.

F-10

After the delivery of the product, there is no uncertainty about customer acceptance due to the nature of the product. There is no contingency for acceptance, warranty, or price protection. We do not recognize revenue on consigned sales until the customer notifies us that the products have been used. In order to determine whether collection is reasonably assured, we assess a number of factors, including past transaction history with the customer and the creditworthiness of the customer. If we determine that collection is not reasonably assured, we defer the recognition of revenue until collection becomes reasonably assured, which is generally upon receipt of payment. We provide for product returns at the time revenue is recognized based on our product return history.

Based on these policies, we recognize revenue, net of allowances for returns and discounts, as products are shipped, based on shipping point terms, or at the time consigned inventory is consumed at which time title passes to customers. We recognize revenue net of allowances for returns and discounts, at the time of shipment of our products to our distributors. Customers returning products are entitled to full or partial credit based on the condition and timing of the return. To be accepted, a returned product must be unopened (if sterile), unadulterated, and undamaged, must have at least 18 months remaining prior to its expiration date, or twelve months for our hospital customers in Europe, and generally be returned within 30 days of shipment. These return policies apply to sales to both hospitals and distributors. The amount of products returned to us, either for exchange or credit, has not been material. Nevertheless, we provide for an allowance for future sales returns based on historical return experience. Our cost of replacing defective products has not been material and is accounted for at the time of replacement.

Research and Development Expense

Research and development costs, principally salaries, laboratory testing, and supplies, are expensed as incurred and also include royalty payments associated with licensed and acquired intellectual property.

Shipping and Handling Costs

Shipping and handling fees paid by customers are recorded within net sales, with the related expense recorded in cost of sales.

Advertising Costs

Advertising costs are expensed as incurred and are included as a component of sales and marketing expense in the accompanying consolidated statements of operations. Advertising costs are as follows:

	Year ended December 31,
	2013		2012		2011
			(in thousands)
Advertising expense	$	421	$	717	$	410

Cash and Cash Equivalents

We consider all highly liquid instruments purchased with maturity dates of 90 days or less to be cash equivalents. Cash and cash equivalents are primarily invested in money market funds. These amounts are stated at cost, which approximates fair value.

Concentrations of Credit Risk

Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, accounts receivable, and notes receivable. Cash equivalents represent highly liquid investments with maturities of 90 days or less at the date of purchase. Marketable securities are investment grade, interest-earning securities and are diversified by type and industry. Credit risk related to cash, cash equivalents, and marketable securities are limited based on the creditworthiness of the financial institutions at which these funds are held. Credit risk related to notes receivable is assessed based upon the individual payor as of the original fair value determination and updated periodically as required.

F-11

Our accounts receivable are with customers based in the United States and internationally. Accounts receivable generally are due within 30 to 90 days of invoice and are stated at amounts due from customers, net of an allowance for doubtful accounts and sales returns, other than in certain European markets where longer payment terms are customary and may range from 90 to 240 days. We perform ongoing credit evaluations of the financial condition of our customers and adjust credit limits based upon payment history and the current creditworthiness of the customers, as determined by a review of their current credit information. We continuously monitor aging reports, collections, and payments from customers, and maintain a provision for estimated credit losses based upon historical experience and any specific customer collection issues we identify.

We closely monitor outstanding receivables for potential collection risks, including those that may arise from economic conditions, in both the U.S. and international economies. Our European sales to government-owned or supported customers such as hospitals, distributors and agents, in Southern Europe, specifically Italy and Spain may be subject to significant payment delays due to government austerity measures impacting funding and payment practices. As of December 31, 2013 our receivables in Italy and Spain totaled $1.2 million and $0.5 million, respectively. Receivables balances with certain publicly-owned hospitals and government supported customers in these countries can accumulate over a period of time and then subsequently be settled as large lump sum payments. While we believe our allowance for doubtful accounts in these countries is adequate as of December 31, 2013, if significant changes were to occur in the payment practices of these European governments or if government funding becomes unavailable, we may not be able to collect on receivables due to us from these customers and our write offs of uncollectible amounts may increase.

We write off accounts receivable when they become uncollectible. Such credit losses have historically been within our expectations and allowances. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for doubtful accounts on a monthly basis and all past due balances are reviewed individually for collectability. The provision for the allowance for doubtful accounts is recorded in general and administrative expenses. The following is a summary of our allowance for doubtful accounts and sales returns:

	Balance at Beginning of Period		Additions Charged to Income		Deductions from Reserves		Balance at End of Period
	(in thousands)
Allowance for doubtful accounts and sales returns:
Year ended December 31, 2013	$	326	$	29	$	92	$	263
Year ended December 31, 2012		211		153		38		326
Year ended December 31, 2011		184		56		29		211

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, marketable securities, accounts receivable, trade payables, and notes payable. The fair value of the majority of these instruments approximates their carrying value based upon their short-term nature or variable rates of interest.

Inventory

Inventory consists of finished products, work-in-process, and raw materials. We value inventory at the lower of cost or market value. Cost includes materials, labor, and manufacturing overhead and is determined using the first-in, first-out (FIFO) method. On a quarterly basis, we review inventory quantities on hand and analyze the provision for excess and obsolete inventory based primarily on product expiration dating and our estimated sales forecast, which is based on sales history and anticipated future demand. Our estimates of future product demand may not be accurate, and we may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated changes in demand could have a significant impact on the value of our inventory and results of operations.

F-12

Property and Equipment

Property and equipment are recorded at cost. Depreciation is provided over the estimated useful lives of the related assets using straight-line method as follows:

Description	Useful Life
Computers and equipment	3–5 years
Machinery and equipment	3–10 years
Leasehold improvements	The shorter of its useful life or lease term

Expenditures for maintenance and repairs are charged to operations when incurred, while additions and betterments are capitalized. When assets are retired or disposed, the asset’s original cost and related accumulated depreciation are eliminated from the accounts and any gain or loss is reflected in the statement of operations.

Valuation of Business Combinations

We assign the value of the consideration transferred to acquire a business to the tangible assets and identifiable intangible assets acquired and liabilities assumed on the basis of their fair values at the date of acquisition. We assess the fair value of assets, including intangible assets, using a variety of methods and are usually performed by an independent appraiser who measures fair value from the perspective of a market participant.

Acquisitions have been accounted for using the acquisition method, and the acquired companies’ results have been included in the accompanying consolidated financial statements from their respective dates of acquisition. Acquisition transaction costs have been recorded in general and administrative expenses, and are expensed as incurred. Allocation of the purchase price for acquisitions is based on estimates of the fair value of the net assets acquired and, for acquisitions completed within the past year, is subject to adjustment upon finalization of the purchase price allocation.

Our acquisitions have historically been made at prices above the fair value of the acquired assets, resulting in goodwill, due to expectations of synergies of combining the businesses. These synergies include use of our existing commercial infrastructure to expand sales of the acquired businesses’ products, use of the commercial infrastructure of the acquired businesses to cost-effectively expand sales of our products, and the elimination of redundant facilities, functions and staffing.

Contingent Consideration

The Financial Accounting Standards Board (the FASB) requires contingent consideration be recognized at the date of acquisition, based on the fair value at that date, and then re-measured periodically through adjustments to net income.

Impairment of Long-lived Assets

We review our long-lived assets (primarily property and equipment and intangible assets) subject to amortization quarterly to determine if any adverse conditions exist or a change in circumstances has occurred that would indicate impairment or a change in the remaining useful life. Conditions that may indicate impairment include, but are not limited to, a significant adverse change in legal factors or business climate that could affect the value of an asset, a product recall, or an adverse action or assessment by a regulator. If an impairment indicator exists, we test the intangible asset for recoverability. We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. Impairment is measured based on the fair market value of the affected asset using discounted cash flows.

In 2011, we determined that certain patents within our portfolio in the United States and Europe had no value based upon an analysis of expected economic benefits. As a result, we recorded an impairment charge of $0.1 million for the write-down of these patents.

F-13

This impairment adjustment falls within Level 3 of the fair value hierarchy, due to the use of significant unobservable inputs to determine fair value. The fair value measurements were calculated using unobservable inputs, primarily using the income approach, specifically the discounted cash flow method. The amount and timing of future cash flows within our analysis was based on our most recent operational budgets, long range strategic plans and other estimates.

Goodwill

Goodwill represents the amount of consideration paid in connection with business acquisitions in excess of the fair value of assets acquired and liabilities assumed. Goodwill is evaluated for impairment annually or more frequently if indicators of impairment are present or changes in circumstances suggest that an impairment may exist. We evaluate the December 31 balance of the carrying value of goodwill based on a single reporting unit annually. We perform an assessment of qualitative factors to determine if it is “more likely than not” that the fair value of our reporting unit is less than its carrying value as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The “more likely than not” threshold is defined as having a likelihood of more than 50 percent. If required, the next step of the goodwill impairment test is to determine the fair value of the reporting unit. The implied fair value of goodwill is determined on the same basis as the amount of goodwill recognized in connection with a business combination. Specifically, the fair value of a reporting unit is allocated to all of the assets and liabilities (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination as of the date of the impairment review and as if the fair value of the reporting unit was the price paid to acquire the reporting unit. The excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. We have determined that no goodwill impairment charges were required for the years ended December 31, 2013, 2012, or 2011.

Other Intangible Assets

Other intangible assets consist primarily of patents, trademarks, technology licenses, and customer relationships acquired in connection with business acquisitions and asset acquisitions and are amortized over their estimated useful lives, ranging from 1 to 13 years.

Stock-based Compensation

We recognize, as expense, the estimated fair value of stock options to employees which is determined using the Black-Scholes option pricing model. We have elected to recognize the compensation cost of all share-based awards on a straight-line basis over the vesting period of the award. In periods that we grant stock options, fair value assumptions are based on volatility, interest, dividend yield, and expected term over which the stock options will be outstanding. The computation of expected volatility is based on the historical volatility of the company’s stock. The interest rate for periods within the contractual life of the award is based on the U.S. Treasury risk-free interest rate in effect at the time of grant. Historical data on exercise patterns is the basis for estimating the expected life of an option. The expected annual dividend rate was calculated by dividing our annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date.

We also issue restricted stock units (RSUs) as an additional form of equity compensation to our employees, officers, and directors, pursuant to our stockholder-approved 2006 Plan. RSUs entitle the grantee to an issuance of stock at no cost and generally vest over a period of time determined by our Board of Directors at the time of grant based upon the continued service to the company. The fair market value of the award is determined based on the number of RSUs granted and the market value of our common stock on the grant date and is amortized to expense over the period of vesting. Unvested RSUs are forfeited and canceled as of the date that employment or service to the company terminates. RSUs are settled in shares of our common stock upon vesting. We may repurchase common stock upon our employees’ vesting in RSUs in order to cover any minimum tax withholding liability as a result of the RSUs having vested.

F-14

Share-based compensation charges are recorded net of the estimated forfeitures based upon historical rates and will be adjusted in future periods to reflect the results of actual forfeitures and vesting. Share-based compensation charges are recorded across the consolidated statement of operations based upon the grantee’s primary function.

Commitments and Contingencies

In the normal course of business, we are subject to proceedings, lawsuits, and other claims and assessments for matters related to, among other things, patent infringement, business acquisitions, employment, and product recalls. We assess the likelihood of any adverse judgments or outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual issue. The required reserves may change in the future due to new developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters. We record charges for the losses we anticipate incurring in connection with litigation and claims against us when we conclude a loss is probable and we can reasonably estimate these losses. During the years ended December 31, 2013, 2012, and 2011, we were not subject to any material litigation or claims and assessments.

Income Taxes

We account for income taxes under the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred taxes are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. The provision for income taxes includes taxes currently payable and deferred taxes resulting from the tax effects of temporary differences between the financial statement and tax bases of assets and liabilities. We maintain valuation allowances where it is more likely than not that all or a portion of a deferred tax asset will not be realized. Changes in the valuation allowances are included in our tax provision in the period of change. In determining whether a valuation allowance is warranted, we evaluate factors such as prior earnings history, expected future earnings, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset.

We recognize, measure, present and disclose in our financial statements, uncertain tax positions that we have taken or expect to take on a tax return. We recognize in our financial statements the impact of tax positions that meet a “more likely than not” threshold, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement.

Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense.

Comprehensive Income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Other than reported net income, comprehensive income includes foreign currency translation adjustments, which are disclosed in the accompanying consolidated statements of comprehensive income. There were no reclassifications out of comprehensive income for the years ended December 31, 2013 and 2012.

Accumulated other comprehensive loss consisted of foreign currency translation adjustment losses of $0.3 million and $0.4 million as of December 31, 2013 and 2012, respectively.

Restructuring

We record restructuring charges incurred in connection with consolidation or relocation of operations, exited business lines, reductions in force, or distributor terminations. These restructuring charges, which reflect our commitment to a termination or exit plan that will begin within twelve months, are based on estimates of the

F-15

expected costs associated with site closure, legal matters, contract terminations, severance payments, or other costs directly related to the restructuring. If the actual cost incurred exceeds the estimated cost, an additional charge to earnings will result. If the actual cost is less than the estimated cost, a credit to earnings will be recognized.

Earnings per Share

We compute basic earnings per share by dividing net income available for common stockholders by the weighted average number of shares outstanding during the year. Except where the result would be anti-dilutive to net income per share, diluted earnings per share has been computed using the treasury stock method and reflects the potential vesting of restricted common stock and the potential exercise of stock options, as well as their related income tax effects.

The computation of basic and diluted net income per share is as follows:

	Year ended December 31,
	2013		2012		2011
	(in thousands, except per share data)
Basic:
Net income available for common stockholders	$	3,202	$	2,571	$	2,143
Weighted average shares outstanding		15,317		15,194		15,458
Basic earnings per share	$	0.21	$	0.17	$	0.14
Diluted:
Net income available for common stockholders	$	3,202	$	2,571	$	2,143
Weighted-average shares outstanding		15,317		15,194		15,458
Common stock equivalents, if dilutive		447		444		531
Shares used in computing diluted earnings per common share		15,764		15,638		15,989
Diluted earnings per share	$	0.20	$	0.16	$	0.13
Shares excluded in computing diluted earnings per share as those shares would be anti-dilutive		373		549		355

Recent Accounting Pronouncements

In February 2013, the FASB issued new guidance which requires disclosure of changes in accumulated other comprehensive income balances by component and significant reclassification adjustments from accumulated other comprehensive income in a single note or on the face of the financial statements. This guidance became effective January 1, 2013. The adoption of this standard, which is related to disclosure only, did not have an impact on our results of operations or financial position.

In July 2013, the FASB issued guidance to address the diversity in practice related to the financial statement presentation of unrecognized tax benefits as either a reduction of a deferred tax asset or a liability when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

2. Acquisitions and Divestitures

XenoSure Manufacturing and Distribution Rights

In October 2012, we entered into an Asset Purchase Agreement (the Neovasc Agreement) with Neovasc, Inc. and its subsidiary, Neovasc Medical Inc. (collectively Neovasc) to acquire the manufacturing and distribution rights of the XenoSure biologic vascular patch. Previously, we were the exclusive distributor of the

Schaublin Medica SA Distribution Agreement

In October 2012, we entered into a definitive agreement with Schaublin Medica SA (Schaublin) to terminate its distribution of our products in Switzerland and to acquire certain assets and rights from Schaublin effective as of January 1, 2013 for $0.2 million. The purchase price was paid in three equal installments in October 2012, January 2013, and January 2014. We recorded $0.1 million of intangible assets and recognized a $0.1 million of transition services as selling expense. We allocated the payment to the tangible and intangible assets acquired based on the estimated fair value of each of these elements to the transaction. The weighted-average amortization period for these intangibles as of December 31, 2012 was 7.0 years.

TryTech Distribution Agreement

In December 2012, we entered into a definitive agreement with TryTech Corporation (TryTech) to terminate its distribution of our products in a certain Japanese territory and to acquire certain assets and rights from TryTech effective as of April 1, 2013 for $0.1 million. The purchase price is due in three equal installments with payments made in December 2012 and March 2013 with the final payment due in March 2014. We recorded $0.1 million of intangible assets and recognized $20,000 of transition services as selling expense. We allocated the payment to the tangible and intangible assets acquired based on the estimated fair value of each of these elements to the transaction. The weighted-average amortization period for these intangibles as of December 31, 2012 was 3.0 years.

Medistim Norge AS Distribution Agreement

In October 2013, we entered into a definitive agreement with Medistim Norge AS (Medistim) to terminate its distribution of our products in Norway and to acquire certain assets and rights from Medistim effective as of January 1, 2014 for $0.2 million. The purchase price is due in three installments with payments made in October 2013 and January 2014 with the final payment due in December 2014.

Tag Medical Pty Ltd Distribution Agreement

In October 2013, we entered into a definitive agreement with Tag Medical Pty Ltd (Tag) to terminate its distribution of our products in Australia and to acquire certain assets and rights from Tag effective as of January 1, 2014 for $0.2 million. The purchase price is due in three installments with payments made in November 2013 and January 2014 and the final payment due in December 2014. We allocated the payment to the tangible and intangible assets acquired based on the estimated fair value of each of these elements to the transaction. The weighted-average amortization period for these intangibles as of December 31, 2013 was 4.8 years.

OptiLock Implantable Port

On June 1, 2010, we sold our OptiLock Implantable Port product line to Minvasive Ltd. (Minvasive). In exchange for consideration of approximately $0.2 million, Minvasive received our existing inventory, tangible and intangible assets, and a customer list associated with the product line. Payment terms included $30,000 due at signing, with the remaining balance to be paid in the form of a royalty on future sales. In May 2012, Minvasive provided notice that it was filing for insolvency protection under German law. As a result, we wrote-off the remaining balance of approximately $52,000 as a loss on divestitures during the three months ended June 30, 2012.

TAArget and UniFit Stent Grafts

On June 30, 2011, we sold our TAArget and UniFit stent graft product lines to Duke Vascular, Inc. (Duke). In exchange for consideration of approximately $0.1 million in cash and a $0.5 million promissory note, Duke received most of our existing inventory, tangible and intangible assets, and a customer list associated with the product lines. In addition, Duke assumed our future obligations associated with the UNITE and ENTRUST clinical trials. We received the initial cash payment on June 30, 2011. The $0.5 million promissory note bore interest at 7% and was payable on June 30, 2012. We recorded the estimated fair value of the promissory note as $0.2 million receivable in other long

F-19

term assets. As a result of this transaction we recorded a net charge of approximately $0.4 million in cost of sales during the year ended December 31, 2011. In 2012, we received $0.5 million which was applied to the outstanding promissory note balance of $0.2 million, interest income, and as a gain on divestiture of $0.3 million.

Endologix Stent Grafts

On July 6, 2011, we entered into an early termination agreement for our distribution rights of Endologix’s stent graft products in Europe. Under the terms of the agreement, we received $1.3 million in exchange for the early termination of our distribution agreement on August 31, 2011, certain customer contracts, our provision of sales and marketing services, and most of our remaining inventory. Previously, we held distribution rights in certain European countries for Endologix’s stent graft products through June 30, 2013. We recognized a gain of $0.7 million upon the termination of the distribution agreement during the year ended December 31, 2011.

The fair market valuations associated with these transactions fall within Level 3 of the fair value hierarchy, due to the use of significant unobservable inputs to determine fair value. The fair value measurements were calculated using unobservable inputs, primarily using the income approach, specifically the discounted cash flow method. The amount and timing of future cash flows within our analysis was based on our due diligence models, most recent operational budgets, long range strategic plans and other estimates.

6. Financing Arrangements

As part of the purchase of Biomateriali S.r.l., we assumed a loan from the Italian government under a program that provided funding to certain businesses in Italy through a combination of grants and loans if certain requirements are met. The loan was stated to be payable in ten annual payments through 2018 of principal and interest at an interest rate of 0.74%. The present value of the loan was recorded as of the date the proceeds were received using our incremental borrowing rate. Interest was being imputed on the loan and the amortization was recorded as interest expense. The loan and grant became due in full as a result of the Biomateriali S.r.l. plant closure. As a result, in December 2011, we incurred approximately $0.1 million of restructuring charges related to additional interest and penalties charges, and we made the final payment to the Italian government of $0.5 million.

We have assessed the need for a valuation allowance against our deferred tax assets and continue to carry a valuation allowance against $1.0 million of foreign deferred tax assets and state credits; based on the weight of available evidence, we believe it is more likely than not such assets will not be realized. The valuation allowance against our deferred tax assets may require adjustment in the future based on changes in the mix of temporary differences, changes in tax laws, and operating performance.

In 2013, we released valuation allowances on certain deferred assets associated with foreign subsidiary historical losses as well as state research and development credits. Our assessment considered evidence such as current profitability, utilization of certain available tax assets and liabilities, and projected future earnings. Based on this evidence, we concluded that it was more likely than not that we would generate sufficient pre-tax income in future periods to utilize all of our deferred tax assets in France and Italy and a portion of our deferred tax assets related to state research and development credits.

Realization of our deferred tax assets is dependent on our generating sufficient taxable income in future periods. Although we believe it is more likely than not that future taxable income will be sufficient to allow us to recover substantially all of the value of our deferred tax assets, realization is not assured and future events could cause us to change our judgment. In the event that actual results differ from our estimates, or we adjust these

F-24

estimates in the future periods, further adjustments to our valuation allowance may be recorded, which could materially impact our financial position and net income (loss) in the period of the adjustment. As of December 31, 2013, we have net operating loss carryforwards in France of $3.9 million that do not expire, Spain of $1.5 million that begin to expire in 2029, Italy of $1.1 million that do not expire, Sweden of $0.3 million that do not expire, Switzerland of $0.3 million that begin to expire in 2019 and others of $0.1 million that do not expire. We also have Federal and state tax credit carryforwards of approximately $0.9 million that are available to reduce future tax liabilities, which expire at various dates through 2023, or can be carried forward indefinitely. Approximately $0.1 million of these Federal and state tax credits relate to excess stock compensation deductions and as such, the benefit of these tax deductions will be credited to additional paid-in capital when we receive a cash benefit from these credits being utilized. Ownership changes, as defined by the Internal Revenue Code, may limit the amount of net operating losses and research and experimentation credit carryforwards that can be utilized annually to offset future taxable income and taxes payable.

A provision has not been made for U.S. or additional non-U.S. taxes on $1.4 million of undistributed earnings of international subsidiaries that could be subject to taxation if remitted to the U.S. because we plan to keep these amounts permanently reinvested overseas except for instances where we can remit such earnings to the U.S. without an associated net tax cost. However, to the extent such foreign earnings were remitted in the future a deferred tax liability of $0.5 million would be recorded.

In January 2013, legislation was signed into law which retroactively reinstated various tax provisions which had previously expired January 1, 2012, principally related to the Federal R&D credit. As this legislation was enacted in January 2013, our financial statements reflect the effects of the legislation in 2013. Had this tax legislation been enacted in 2012, we would have recognized an additional $0.2 million of additional U.S. tax credits in our consolidated financial statements for the year ending December 31, 2012.

A reconciliation of the Federal statutory rate to our effective tax rate is as follows:

	2013			2012			2011
Federal statutory rate		34.0	%		34.0	%		34.0	%
State tax, net of federal benefit		0.4	%		2.3	%		1.7	%

In March 2014, the German tax authority notified our German subsidiary that the tax years 2009 through 2012 would be audited. We expect the audit to commence during the third quarter of 2014. We believe there will be no material changes to its income tax liability as a result of this audit. We are not currently under audit in any other tax jurisdictions. As of December 31, 2013, a summary of the tax years that remain subject to examination in our most significant tax jurisdictions are:

United States	2010 and forward
Foreign	2007 and forward

10. Stockholders’ Equity

Authorized Shares

On June 14, 2012, our stockholders approved an amendment (Charter Amendment) to our Second Amended and Restated Certificate of Incorporation to reduce the number of authorized shares of common stock from 100,000,000 to 37,000,000 shares and of undesignated preferred stock from 5,000,000 to 3,000,000 shares. The Charter Amendment was previously approved by our Board of Directors on April 12, 2012, subject to approval by our stockholders. The Charter Amendment was filed with the Secretary of State of the State of Delaware on June 14, 2012.

Stock Award Plans

Under our 1997, 1998, 2000, and 2004 stock option plans, we authorized for the granting of options in the form of incentive stock options or non-qualified stock options to employees, directors, and consultants to purchase up to 1,688,702 shares of common stock. The stock options provide the holder the right to purchase common stock at a specific exercise price and the expected term will not exceed ten years. Incentive stock options are required to be issued at not less than fair market value at the date of the grant and generally vest over four or five years. The term of the options is determined by our Board of Directors but in no event will exceed ten years from date of grant, except with respect to one non-qualified option issued under our 1997 stock option plan.

In May 2006 we approved a 2006 Stock Option and Incentive Plan (the 2006 Plan), which became effective upon the initial public offering. In 2010 we amended the 2006 Plan to increase the aggregate pool of available shares to 3,000,000 of common stock. The plan allows for granting of incentive stock options, non-qualified stock options, stock appreciation rights, RSUs, unrestricted stock awards, and deferred stock awards to our officers, employees, directors, and consultants. In connection with the adoption of the 2006 Plan, no further option grants are permitted under the 1997, 1998, 2000, and 2004 stock option plans and any expirations, cancellations, or terminations under the previous plans are available for issuance under the 2006 Plan. We may satisfy awards upon exercise of stock options or RSUs with either newly issued or treasury shares. The total number of shares currently authorized for stock award plans is 4,618,003 of which approximately 783,012 remain available for grant as of December 31, 2013.

We have computed the fair value of employee stock options using the following weighted average assumptions:

	2013			2012			2011
Dividend yield		1.8	%		1.6	%		1.1	%
Volatility		57.8	%		61.8	%		66.1	%
Risk-free interest rate		1.5	%		0.6	%		1.4	%
Weighted average expected option term (in years)		5.5			5.5			4.8

(2) The aggregate intrinsic value represents the difference between the exercise price and the closing price of our stock on the day of exercise.

(3) The aggregate intrinsic value represents the difference between the exercise price and $8.01, the closing price of our stock on December 31, 2013, for all in-the-money options outstanding.

(4) Options outstanding that are expected to vest are net of estimated future option forfeitures in accordance with the provisions set forth by the FASB.

Restricted Stock Units

A summary of our RSU activity, which is subject to fair value accounting requirements, is as follows:

Balance outstanding at December 31, 2013		254,297		$	6.25

(1) The number of RSUs vested includes the shares that we withheld on behalf of employees to satisfy minimum statutory tax withholding requirements.

The fair values of the RSUs that vested during 2013, 2012, and 2011 were $0.8 million, $0.7 million, and $0.9 million, respectively.

We repurchase shares of our common stock in order to cover any minimum tax withholding liability associated with RSU vestings. A summary of our repurchases is as follows:

	2013		2012
Shares of common stock repurchased		41,259		42,991

We expect to record the unamortized portion of share-based compensation expense of $2.6 million for existing stock options and RSUs outstanding at December 31, 2013, over a weighted-average period of 3.4 years.

Stock Repurchase Plan

In July 2009, our Board of Directors authorized a repurchase of our common stock from time to time on the open market or in privately negotiated transactions. In November 2011, our Board of Directors increased this authorization to $10.0 million and extended the program through December 31, 2013. The timing and number of any shares repurchased will be determined based on our evaluation of market conditions and other factors. Repurchases may also be made under a Rule 10b5-1 plan, which would permit shares to be repurchased when we might otherwise be precluded from doing so under insider trading laws. The repurchase program concluded as of December 31, 2013. The following is a summary of the stock repurchase activity for the year ended.

Dividends

On February 24, 2011, our Board of Directors approved a policy for the payment of quarterly cash dividends on our common stock. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by our Board of Directors on a quarterly basis. The dividend activity for the periods presented is as follows:

11. Profit-Sharing Plan

We offer a 401(k) profit-sharing plan (the Plan) covering eligible U.S. employees to make tax deferred contributions, a portion of which are matched by us. We may make discretionary profit sharing contributions to the Plan in an amount determined by our Board of Directors. Our contributions vest ratably over six years of employment and amounted to approximately $40,000 for 2013 and were $0.1 million for 2011. Our 2012 contributions were funded from employee forfeitures.

12. Restructuring Charges

In October 2010, we adopted a reorganization plan (Biomateriali Plan) that was designed to eliminate redundant costs resulting from our 2007 acquisition of Biomateriali and to improve efficiencies in our manufacturing operations. In 2011, we incurred $0.3 million of charges associated with the transfer of manufacturing equipment to our Burlington factory and $0.7 million of non-cash charges related to the write-down of an asset for deferred rent, which was triggered by our exit of the Biomateriali facility in March 2011, and $0.1 million related to the repayment of grants and loans received from the Italian government associated with business incentive programs for the Biomateriali facility. We paid $0.4 million of severance related charges in 2011 and paid remaining $0.2 million in February 2012. We made the final payment to the Italian government of $0.5 million in December 2011. In March 2012, we completed the Biomateriali liquidation and dissolution process.

In May 2011, we adopted a reorganization plan (LifeSpan Plan) that was designed to eliminate redundant costs resulting from our 2010 acquisition of the LifeSpan vascular graft and to improve efficiencies in our manufacturing operations. We transitioned the production of our LifeSpan vascular graft from Laguna Hills, California to our existing corporate headquarters in Burlington, Massachusetts. The LifeSpan Plan resulted in the termination of 7 employees at the Laguna Hills facility, relocation of manufacturing equipment, and the hiring of 4 employees to staff the required functions in Burlington. We incurred approximately $0.1 million related to the closure of the Laguna Hills facility and the related relocation of the manufacturing equipment during the year ended December 31, 2011. We incurred approximately $33,000 of severance charges related to this project during year ended December 31, 2011.

On June 30, 2011, we terminated our relationship with our Spanish distributor resulting in a contract termination charge of $0.5 million which we recorded as restructuring charges (see Note 2 for further details regarding the transaction).

On June 30, 2011, we terminated our relationship with our Danish distributor resulting in a contract termination charge of $0.1 million which we recorded as restructuring charges (see Note 2 for further details regarding the transaction).

In July 2011, we adopted a reorganization plan of our European administrative and stent graft sales personnel as a result of our exit from our stent graft business. We terminated 6 employees and recorded severance charges of $0.3 million during the year ended December 31, 2011. The final severance payments were made in March 2012.

The components of the restructuring charges are as follows:

In February 2014, we committed to a plan intended to improve operational efficiencies, which includes a reduction in force of approximately 10% of our workforce and other cost-cutting measures. The plan was implemented during the first quarter of 2014. We estimate that termination costs will be $0.2 million to $0.4 million. We expect to record the majority of these charges in 2014.

13. Segment and Enterprise-wide Disclosures

The FASB establishes standards for reporting information regarding operating segments in financial statements. Operating segments are identified as components of an enterprise about which separate, discrete financial information is available for evaluation by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. We view our operations and manage our business as one operating segment. No discrete operating information is prepared by us except for product sales by product line and by legal entity for local reporting purposes.

Most of our revenues were generated in the United States, Germany, Japan, Canada, and other European countries, and substantially all of our assets are located in the United States. Net sales to unaffiliated customers by country were as follows:

	Year ended December 31,
	2013		2012		2011
	(in thousands)
United States	$	39,240	$	36,542	$	35,366

15. Fair Value Measurements

The fair value accounting guidance requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

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

• Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

As of December 31, 2013, we had cash equivalents in a money market fund that was valued using Level 1 inputs (quoted market prices for identical assets) at a fair value of $8.3 million.

We had no Level 2 assets being measured at fair value on a recurring basis as of December 31, 2013.

As discussed in Notes 1and 2, several measurements of acquisition-related assets and impairments of intangible assets were measured using Level 3 techniques. The following table provides a rollforward of the fair value, as determined by Level 3 inputs, of the contingent consideration.

(1) During the second quarter of 2013, we identified an error in our historic inventory valuation that resulted in an understatement of the periodic carrying amount of our inventory. We corrected this error which resulted in an understatement of cost of sales of $0.4 million and an overstatement of net income of $0.3 million in the three months ended June 30, 2013.
