(together with its subsidiaries, "AngioDynamics," the "Company," "we," "our" or "us") designs, manufactures and sells a widerange of medical, surgical and diagnostic devices used by professional healthcare providers for the treatment of peripheral vascular disease, vascular accessand for use in oncology and surgical settings. Our devices are generally used in minimally invasive, image-guided procedures.HISTORYAngioDynamics was founded in Queensbury, N.Y., U.S., in 1988. Queensbury was chosen due to its location in the heart of "Catheter Valley," an area inNew York's Adirondack Region named for its long history of catheter and other medical device manufacturing. Initially dedicated to the research anddevelopment of products used in interventional radiology, AngioDynamics began manufacturing and shipping product in the early 1990s. The Companysoon became well established as a producer of diagnostic catheters for non-coronary angiography and thrombolytic delivery systems.The company grew over the following years as a result of acquisitions of companies including RITA Medical Systems in January 2007, Oncobionic inMay 2008, the assets of Diomed in June 2008 and FlowMedica in January 2009. These acquisitions added product lines including market-leading ablationand NanoKnife systems, vascular access products, angiographic products and accessories, dialysis products, drainage products, thrombolytic products,embolization products, venous products and targeted renal therapy products. More recently in May 2012, AngioDynamics acquired Navilyst Medical,bringing market-leading fluid management systems into our portfolio. The acquisition significantly expanded the Company's scale, doubling its share of thevascular access market while building critical mass in the peripheral vascular market.Headquartered in Latham, N.Y., AngioDynamics is publicly traded on the NASDAQ stock exchange under the symbol ANGO.PRODUCTSOur product offerings fall within three Global Business Units (GBUs): Peripheral Vascular, Vascular Access and Oncology/Surgery. All productsdiscussed below have been cleared for sale in the United States by the Food and Drug Administration (FDA). International regulatory clearances vary byproduct and jurisdiction. Peripheral Vascular ProductsAngioDynamics’ Peripheral Vascular product offerings support the medical areas of Venous Insufficiency, Thrombus Management, Fluid Managementand Peripheral Products (Core).Venous InsufficiencyVenaCure EVLT laser systemOur VenaCure EVLT (endovenous laser treatment) system products areused in endovascular laser procedures to treat superficial venous disease(varicose veins). Superficial venous disease is a malfunction of one or morevalves in the leg veins whereby blood refluxes or does not return to the heart,thereby pooling in the legs and leading to symptoms such as pain, swellingand skin changes. VenaCure EVLT uses laser energy to stop the reflux byablating (collapsing and destroying) the affected vein. Blood is then re-routed to other healthy veins. 2The procedure is minimally invasive and generally takes less than an hour, allowing the patient to quickly return to normal activities with minimal post-operative pain. More than one million VenaCure EVLT procedures have been performed.VenaCure EVLT is sold as a system that includes diode laser hardware and procedure kits which include disposable laser fiber components, an accesssheath, access wires and needles. Our VenaCure EVLT 1470 nanometer wavelength laser allows physicians to more efficiently heat the vein wall using lowerpower settings thereby reducing the risk of collateral damage. The NeverTouch tip fiber eliminates laser tip contact with the vein wall, which in turnminimizes perforations of the vein wall that typically result in less pain and bruising as compared to traditional bare-tip fibers. The NeverTouch tip alsomaximizes ultrasonic visibility, making it easier for physicians to use. Procedure kits are available in a variety of lengths and configurations to accommodatevaried patient anatomies.The VenaCure EVLT system comes with a comprehensive physician training program and extensive marketing support.Asclera (polidocanol) InjectionAsclera (polidocanol) injection is the only FDA-approved sclerosant with an indication to treat uncomplicated spider veins and uncomplicated reticularveins in the lower extremity. AngioDynamics distributes Asclera through a global agreement with the manufacturer and their distributor. In a multicenter,randomized, double-blind, placebo and comparator-controlled trial in patients with spider or reticular varicose veins, 95% of patients treated with Asclerashowed good improvement or complete treatment success as rated by physicians and 87% of patients were satisfied or very satisfied with their Ascleratreatment. ¹Polidocanol can be produced through compounding, but only in certain situations and for specific medical needs. In July 2016, the FDA draftedguidance clarifying the parameters for compounding essentially copies of approved and/or commercially available drug products due to the higher risk forpatients versus those that have been FDA approved.Thrombus ManagementOur Thrombus Management portfolio includes the proprietary AngioVac venous drainage cannula and circuit, as well as catheter directed thrombolyticdevices and Uni-Fuse infusion catheters. AngioDynamics offers a range of options when treating thrombus and removing fresh, soft thromboli or emboli.AngioVacOur AngioVac venous drainage system includes a Venous DrainageCannula and Extracorporeal Circuit. The cannula is indicated for use as avenous drainage cannula and for removal of fresh, soft thrombi or emboliduring extracorporeal bypass. The cardiopulmonary bypass circuit isindicated for use in procedures requiring extracorporeal circulatory supportfor periods of up to six hours. AngioVac devices are for use with othermanufacturers’ off-the-shelf pump, filter and reinfusion cannula, to facilitatevenous drainage as part of an extracorporeal bypass procedure. The AngioVac venous drainage cannula is a 22 French coil-reinforced cannula designed with a balloon actuated, expandable funnel shaped distal tip.The proprietary funnel shaped tip enhances venous drainage flow when the balloon is inflated, prevents clogging of the cannula with commonly encounteredundesirable intravascular material, and facilitates en bloc removal of such extraneous material.¹ Weiss, Voigts, Howell (2011) Absence of Concentration Congruity in Six Compounded Polidocanol Samples Obtained for Leg Sclerotherapy. American Society forDermatologic Surgery, Inc., Volume 37: 1-43Thrombolytic CathetersThrombolytic catheters are used to deliver thrombolytic agents, which are drugs that dissolve blood clots in hemodialysis access grafts, arteries, veinsand surgical bypass grafts. AngioDynamics’ Uni-Fuse infusion catheter features pressure response outlets, a patented, time-tested slit technology thatprovides a consistent, even distribution of fluid volume along the entire length of the infusion pattern, resulting in a 12-fold advantage over standard side-hole catheters.²We also offer the Pulse-Spray infusion system for high pressure, pulsed delivery of lytic agent to shorten treatment time, and the Speed Lyser infusionsystem built for dialysis grafts and fistulas.Fluid ManagementOur Fluid Management product offerings include the NAMIC® Fluid Management portfolio. Since 1969, the NAMIC product line has been a leader inproviding clinicians high quality, dependable devices that help in the diagnosis and treatment of cardiovascular and peripheral vascular disease. The NAMICproduct line includes an extensive offering of manifolds, contrast management systems, closed fluid systems, guidewires, disposable transducers andinterventional accessories. These devices are utilized together and allow clinicians to aspirate or inject contrast, saline, remove waste and monitor invasiveblood pressures throughout the procedure.Peripheral Products (Core)We offer a comprehensive portfolio for minimally invasive peripheral products. Product categories include an extensive line of angiographic cathetersand diagnostic and interventional guidewires, percutaneous drainage catheters and coaxial micro-introducer kits.Angiographic Products and AccessoriesAngiographic products and accessories are used during peripheral diagnostic and interventional procedures. These products permit physicians to reachtargeted locations to deliver contrast media for visualization purposes and therapeutic agents and devices, such as percutaneous transluminal angioplasty(PTA) balloons. Angiographic products consist of angiographic catheters and guidewires.Our angiographic catheter line includes the following brands, all with radiopaque tips to assure excellent visibility under fluoroscopy:•Soft-Vu flush catheters are available in flush and selective varieties. Flush Catheters are used in procedures where a high flow of contrast is requiredfor “big picture” diagnostics. Anomalies discovered through a flush angiogram may require further investigation into a vessel of interest. Soft-Vuselective catheters are used to gain access to smaller or more distal vessels and advance the catheter or wire into the diseased section.•Accu-Vu sizing catheters feature radiopaque marker bands at the distal (farthest away) portion of the catheter to provide a highly accuratemeasurement of the patient’s anatomy. This enables precise measurement for interventional devices (stents, filters, etc.)•AngiOptic catheters have total catheter radiopacity, ensuring tip-to-hub visibility. This catheter is also constructed with a firm tip material thatenhances stability during high-flow injections, providing excellent pushability.•Mariner catheters have a hydrophilic coating that, when combined with water, reduces friction. This makes insertion potentially easier and morecomfortable for the patient, and can also be used for advancing through tortuous anatomy.AngioDynamics guidewires include Nit-Vu (featuring a kink-resistant NiTi alloy core facilitating smooth navigation through tortuous vasculature andaccurate wire control) and PTFE Coated (fixed core and movable core) diagnostic guidewires.AngioDynamics catheters and guidewires are available in more than 500 tip configurations and lengths.² Yusuf SW, et al.

British Journal of Surgery 1995; 82:338-340.4Drainage ProductsDrainage products percutaneously drain abscesses and other fluid pockets. An abscess is a tender inflamed mass that typically must be drained by aphysician. AngioDynamics offers two brands of drainage catheters for multi-purpose/general, nephrostomy and biliary drainage: Total Abscession andExodus. Each offer features and benefits depending on case presentation and physician preferences.Micro Access KitsOur Micro Access sets provide interventional physicians a smaller introducer system for minimally-invasive procedures. Our Micro Access product lineprovides physicians with the means to choose from the wide selection of configurations, including guidewire, needle and introducer options. Two lines areavailable in stiff/standard, 10cm or 15cm and echogenic for visibility under ultrasound guidance: Micro Introducer Kit and Ministick Max.Vascular Access ProductsOur portfolio of Vascular Access products includes a broad offering of peripherally inserted central catheters (PICCs), midline catheters, implantableports, dialysis catheters and related accessories and supplies. These products are used to deliver, primarily, short-term drug therapies, such aschemotherapeutic agents and antibiotics, into the central venous system. Delivery to the circulatory system allows drugs to mix with a large volume of bloodas compared to intravenous drug delivery into a superficial vessel. Our Vascular Access product family also includes the proprietary BioFlo catheter.BioFlo® AngioDynamics offers BioFlo, the only catheter on the market withEndexo Technology, a material more resistant to thrombus accumulation, invitro (based on platelet count). Endexo Technology is a permanent and non-eluting polymer that is “blended” into the polyurethane from which thecatheter is made. It is present throughout the catheter, including theextraluminal, intraluminal and cut catheter surface of the tip. EndexoTechnology remains present for the life of the catheter. BioFlo’s long-termdurability and efficacy is intended to provide clinicians a high degree ofsafety and confidence in providing better patient care and improved patientoutcomes. BioFlo catheters are available across the Vascular Access familyof products, including PICCs, midlines, ports and dialysis catheters. PICCsA peripherally inserted central catheter, or PICC, is a long thin catheter that is inserted into a peripheral vein, typically in the upper arm, and advanceduntil the catheter tip terminates in a large vein in the chest near the heart to obtain intravenous access. PICCs can typically be used for prolonged periods oftime and provide an alternative to central venous catheters. Our PICC product offerings include:•BioFlo® PICC: Our BioFlo line is the only power injectable PICC available that incorporates Endexo Technology into the manufacturing anddesign of the catheter. Advanced features such as large lumen diameters allow the BioFlo® PICC to deliver the power injection flow rates requiredfor contrast-enhanced Computed Tomography (CT) scans compatible with up to 325 psi CT injections.•BioFlo® Midline: The BioFlo Midline Catheter is an effective solution to preserving a patient’s peripheral access. It provides a cost-effectivealternative to multiple IV site rotations for patients who need short-term venous access.•Xcela PICC: The Xcela® PICC line is designed to provide a high degree of safety, ease and confidence in patient care. Advanced features such aslarge lumen diameters allow the Xcela® PICC to deliver the power injection flow rates required for contrast-enhanced CTs compatible with up to 325psi CT injections.•PASV® Valve Technology: The PASV® Valve Technology is available in both BioFlo and Xcela lines and is designed to automatically resistbackflow and reduce blood reflux that could lead to catheter-related complications.5PortsPorts are implantable devices utilized for the central venous administration of a variety of medical therapies and for blood sampling and diagnosticpurposes. Central venous access facilitates a more systemic delivery of treatment agents, while mitigating certain harsh side effects of certain treatmentprotocols and eliminating the need for repeated access to peripheral veins. Depending upon needle gauge size and the port size, a port can be utilized for upto approximately 2,000 accesses once implanted in the body. Our ports are used primarily in systemic or regional short- and long-term cancer treatmentprotocols that require frequent infusions of highly concentrated or toxic medications (such as chemotherapy agents, antibiotics or analgesics) and frequentblood samplings. Our port products and accessories include:•BioFlo® Port: Our BioFlo Port is the only port available that features a catheter with Endexo Technology. Advanced features of the BioFlo Portinclude multiple profile and catheter options, a large septum area for ease of access and the ability to administer contrast through a CT injection forpurposes of imaging.•SmartPort®: The Smart Port power-injectable port with Vortex technology offers the ability for a clinician to access a vein for both the delivery ofmedications or fluids and for administering power-injected contrast to perform a (CT) scan. The ability to access a port for power-injected contraststudies eliminates the need for additional needle sticks in the patient’s arm and wrist veins. Once implanted, repeated access to the bloodstream canbe accomplished with greater ease and less discomfort. Our Smart Port is available in mini and low-profiles to accommodate more patient anatomies.•Vortex®: Our Vortex port technology line of ports is a clear-flow port technology that, we believe, revolutionized port design. With its roundedchamber, the Vortex port is designed to have no sludge-harboring corners or dead spaces. This product line consists of titanium, plastic and dual-lumen offerings.•PASV® Valve Technology: The PASV® Valve Technology is designed to automatically resist backflow and reduce blood reflux that could lead tocatheter-related complications.•LifeGuard®: The LifeGuard Safety Infusion Set and The LifeGuard Vision are used to infuse our ports and complement our port and vascular accesscatheters. The needles’ low profile design is intended to allow clinicians to easily dress the site.Dialysis ProductsWe market a complete line of dialysis products that provide short and long-term vascular access for dialysis patients. Dialysis, or cleaning of the blood, isnecessary in conditions such as acute renal failure, chronic renal failure and end-stage renal disease (ESRD). We currently offer a variety of dialysis catheters,including:•BioFlo® DuraMax: Our BioFlo DuraMax is the only dialysis catheter with Endexo Technology. Advanced features of the BioFlo DuraMax dialysiscatheter include large inner diameter lumens designed for long term patency, a proprietary guidewire lumen to facilitate catheter exchanges andCurved Tip Technology that allows the catheter to self-center in the Superior Vena Cava (SVC).•DuraMax®: The DuraMax catheter is a stepped-tip catheter designed to improve ease of use, dialysis efficiency and overall patient outcomes.In addition, AngioDynamics also offers other renal therapies, including DuraFlow™ Chronic Hemodialysis Catheter, Schon Chronic HemodialysisCatheter, EVENMORE Chronic Hemodialysis Catheter, EMBOSAFE™ Valved, Splitable Sheath Dilator and Perchik™ Button Suture Retention Device.Oncology/Surgery ProductsAngioDynamics offers a range of comprehensive ablation technologies, including thermal tissue ablation systems (microwave energy andradiofrequency energy), surgical resection and the NanoKnife System, an innovative alternative to thermal ablation.6NanoKnife® SystemThe NanoKnife® System is an alternative to traditional thermal ablationthat has received 510(k) clearance from the Food and Drug Administrationfor the surgical ablation of soft tissue. The NanoKnife Ablation Systemutilizes low energy direct current electrical pulses to permanently open poresin target cell membranes. These permanent pores or nano-scale defects in thecell membranes result in cell death. The treated tissue is then removed by thebody’s natural processes in a matter of weeks, mimicking natural celldeath. Unlike other ablation technologies, NanoKnife Ablation System doesnot achieve tissue ablation using thermal energy. The NanoKnife Ablation System consists of two major components: a Low Energy Direct Current, or LEDC Generator and needle-like electrodeprobes. Up to six (6) electrode probes can be placed into or around the targeted soft tissue. Once the probes are in place, the user enters the appropriateparameters for voltage, number of pulses, interval between pulses, and the pulse length into the generator user interface. The generator then delivers a seriesof short electric pulses between each electrode probe. The energy delivery is hyperechoic and can be monitored under real-time ultrasound.Microwave AblationSolero Microwave Tissue Ablation (MTA) SystemThe Solero MTA System features the Solero Microwave (MW) Generatorand the specially designed Solero MW Applicators. The solid state SoleroMW Generator with a 2.45 GHz operating frequency can power up to 140 Wfor optimized power delivery and fast ablations. The Solero MWApplicator’s optimized ceramic tip diffuses MW energy nearly spherically,and its patented cooling channel with thermocouple provides real-timemonitoring to help protect non-targeted tissue ablation. In addition, theSolero MTA System offers physicians scalability with a single applicatordesigned for multiple, predictable ablation volumes by varying time andwattage. Solero is a single applicator system able to complete up to a 5 cmablation in six (6) minutes at maximum power. The Solero MTA System and Accessories are indicated in the U.S. for the ablation of soft tissue during open procedures. The Solero MTA System is notintended for cardiac use.Acculis Microwave Tissue Ablation (MTA) SystemWhen configured for use with the Accu2i pMTA Applicators, the Acculis MTA System includes the Sulis VpMTA Generator, optional MTA TemperatureProbes, Acculis Local Control Station (LCS) and Accu2i pMTA Applicators. Designed for physicians trained in image-guided ablation procedures,intraoperative ultrasound and/or CT guided needle placement, the system is used for thermal coagulation of soft tissue. By utilizing 2.45 GHz of microwaveenergy, the Acculis MTA System can complete ablations up to 5 cm in six minutes with a single applicator. Applicators are available in 14 cm, 19 cm and 29cm lengths, offering flexibility in selecting the appropriate length for the procedure.Radiofrequency AblationStarBurst Radiofrequency Ablation DevicesRadiofrequency Ablation (RFA) products use radiofrequency energy to provide a minimally invasive approach to ablating solid cancerous or benigntumors. Our StarBurst Radiofrequency Ablation Devices deliver radiofrequency energy to raise the7temperature of cells above 45-50°C, causing cellular death. The physician inserts the disposable needle electrode device into the targeted body tissue,typically under ultrasound, CT or Magnetic Resonance Imaging (MRI) guidance.During the procedure, our system automatically adjusts the amount of energy delivered in order to maintain the temperature necessary to ablate thetargeted tissue. For a typical 5 cm ablation using our StarBurst ® Xli-enhanced disposable device, the ablation process takes approximately ten minutes. TheRFA system consists of a radiofrequency generator and a family of disposable devices.In addition to thermal ablation systems and NanoKnife, AngioDynamics also offers Habib 4X Surgical Resection Devices that are used in minimallyinvasive laparoscopic surgery (MILS) procedures in surgical specialties such as Hepato-Biliary, GI, Surgical Oncology, Transplant Surgery and Urology(Partial Nephrectomy Resections). It is clinically indicated to assist in coagulation of tissue during intraoperative and laparoscopic procedures.RESEARCH & DEVELOPMENTOur growth depends in large part on the continuous introduction of new and innovative products, together with ongoing enhancements to our existingproducts. This happens through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend tocontinue to make investments in, research and development (R&D).Our R&D teams work closely with our marketing teams, sales force and regulatory and compliance teams to incorporate customer feedback into ourdevelopment and design process. We believe that we have a reputation among interventional physicians as a strong partner for developing high qualityproducts because of our tradition of close physician collaboration, dedicated market focus, responsiveness and execution capabilities for productdevelopment and commercialization.COMPETITIONWe encounter significant competition across our product lines and in each market in which our products are sold. These markets are characterized byrapid change resulting from technological advances, scientific discoveries and changing customer needs and expectations. We face competitors ranging fromlarge manufacturers with multiple business lines to small manufacturers that offer a limited selection of products.Our primary device competitors include: Boston Scientific Corporation; Cook Medical; C.R. Bard; Medical Components, Inc. (Medcomp); TeleFlexMedical; Smiths Medical, a subsidiary of Smiths Group plc; Medtronic; Merit Medical; Terumo Medical Corporation; Johnson and Johnson and Total VeinSystems.We believe our products compete primarily based on their quality, clinical outcomes, ease of use, reliability, physician familiarity and cost-effectiveness.In the current environment of managed care, which is characterized by economically motivated buyers, consolidation among health care providers, increasedcompetition and declining reimbursement rates, we have been increasingly required to compete on the basis of price. We believe that our continuedcompetitive success will depend upon our ability to develop or acquire scientifically advanced technology, apply our technology cost-effectively acrossproduct lines and markets, attract and retain skilled personnel, obtain patent or other protection for our products, obtain required regulatory andreimbursement approvals, manufacture and successfully market our products either directly or through outside parties, and maintain sufficient inventory tomeet customer demand.SALES AND MARKETINGWe sell our broad line of quality devices in the United States primarily through a direct sales force and internationally through a combination of directsales and distributor relationships. We support our customers and sales organization with a marketing staff that includes product managers, customer servicerepresentatives and other marketing specialists.We focus our sales and marketing efforts on interventional radiologists, interventional cardiologists, vascular surgeons, urologists and interventionaland surgical oncologists.MANUFACTURINGWe manufacture certain proprietary components and products and assemble, inspect, test and package our finished products. By designing andmanufacturing many of our products from raw materials, and assembling and testing our subassemblies and products, we believe that we are able to maintainbetter quality control, ensure compliance with applicable regulatory standards and our internal specifications, and limit outside access to our proprietarytechnology. We have custom-8designed proprietary manufacturing and processing equipment and have developed proprietary enhancements for existing production machinery.We own or lease four primary manufacturing properties providing capabilities which include manufacturing, service, engineering and research,distribution warehouses and offices. These facilities are registered with the FDA and have been certified to ISO 13485 standards, as well as the CMD/CASCanadian Medical Device Regulations. ISO 13485 is a quality system standard that satisfies European Union regulatory requirements, thus allowing us tomarket and sell our products in European Union countries. Our manufacturing facilities are subject to periodic inspections by regulatory authorities to ensurecompliance with domestic and non-U.S. regulatory requirements. See “Government Regulation” section of this report for additional information. See Item 2"Properties" for details on each manufacturing location.In February 2017, we announced the consolidation of our global operations into two facilities located in New York State. Operations being done in theDenmead, U.K. and Manchester, Ga. manufacturing facilities will be consolidated into the Glens Falls and Queensbury, N.Y. facilities.BACKLOGHistorically, we ship the majority of products within 24-48 hours of receiving an order, and accordingly our backlog is not significant. INTELLECTUAL PROPERTYPatents, trademarks and other proprietary rights are very important to our business. We also rely upon trade secrets, manufacturing know-how,technological innovations and licensing opportunities to maintain and improve our competitive position. We regularly monitor and review third-partyproprietary rights, including patents and patent applications, as available, to aid in the development of our intellectual property strategy, avoid infringementof third-party proprietary rights, and identify licensing opportunities.The company owns an extensive portfolio of patents and patent applications in the United States and in certain foreign countries. The portfolio alsoincludes exclusive licenses to third party patents and applications.Most of our products are sold under the AngioDynamics trade name or trademark. Additionally, products are also sold under product trademarks and/orregistered product trademarks owned by AngioDynamics, Inc., or an affiliate or subsidiary. Some products contain trademarks of companies other thanAngioDynamics.See Part I. Item 3 of this report for additional details on litigation regarding proprietary technology.LITIGATIONWe operate in an industry characterized by extensive patent litigation. Patent litigation can result in significant damage awards and injunctions thatcould prevent the manufacture and sale of affected products or result in significant royalty payments in order to continue selling the products. While it is notpossible to predict the outcome of patent litigation incidents to our business, we believe the costs associated with this type of litigation could have a materialadverse impact on our consolidated results of operations, financial position, or cash flows. The medical device industry is also susceptible to significantproduct liability claims. These claims may be brought by individuals seeking relief on their own behalf or purporting to represent a class. In addition, productliability claims may be asserted against us in the future based on events we are not aware of at the present time. At any given time, we are involved in anumber of product liability actions. For additional information, see both Part I. Item 3 of this report and Note 15 to the consolidated financial statements inthis Annual Report on Form 10-K.GOVERNMENT REGULATIONThe products we manufacture and market are subject to regulation by the Food and Drug Administration (FDA) under the Federal Food, Drug, andCosmetic Act, or FDCA, and international regulations to our specific target markets.9United States FDA RegulationBefore a new medical device can be introduced into the market, a manufacturer generally must obtain marketing clearance or approval from the FDAthrough either a 510(k) submission (a premarket notification) or a premarket approval application (PMA).The 510(k) procedure is available only in particular circumstances. The 510(k) clearance procedure is available only if a manufacturer can establish thatits device is “substantially equivalent” in intended use and in safety and effectiveness to a “predicate device,” which is a legally marketed device with 510(k)clearance in class I or II or preamendment status based upon products commercially distributed on or before May 28, 1976. After a device receives 510(k)clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires anew 510(k) clearance. The 510(k) clearance procedure including questions and responses may take up to 12 months. In some cases, supporting clinical datamay be required. The FDA may determine that a new or modified device is not substantially equivalent to a predicate device or may require that additionalinformation, including clinical data, be submitted before a determination is made, either of which could significantly delay the introduction of new ormodified device products. If a device cannot demonstrate substantial equivalence, it may be subject to either a de novo submission or a PMA.The PMA application procedure is more comprehensive than the 510(k) procedure and typically takes several years to complete. The PMA applicationmust be supported by scientific evidence providing pre-clinical and clinical data relating to the safety and efficacy of the device and must include otherinformation about the device and its components, design, manufacturing and labeling. The FDA will approve a PMA application only if a reasonableassurance that the device is safe and effective for its intended use can be provided. As part of the PMA application review, the FDA will inspect themanufacturer’s facilities for compliance with its Quality System Regulation, or QSR. As part of the PMA approval the FDA may place restrictions on thedevice, such as requiring additional patient follow-up for an indefinite period of time. If the FDA’s evaluation of the PMA application or the manufacturingfacility is not favorable, the FDA may deny approval of the PMA application or issue a “not approvable” letter. The FDA may also require additional clinicaltrials, which can delay the PMA approval process by several years. After the PMA is approved, if significant changes are made to a device, its manufacturingor labeling, a PMA supplement containing additional information must be filed for prior FDA approval.Historically, our products have been introduced into the market using the 510(k) procedure and we have never had to use the PMA procedure.The process of FDA submissions requires extensive and expensive validations and testing. The financial outlay for this is large and requires a significantamount of time. Recent changes in both regulations and FDA perspectives have increased both time and testing requirements, which have caused significantdelays and increased costs for approvals. The parameters for increased testing have and will continue to cause severe delays. The increased focus by the FDAon such issues as chemical identification of all colorants, non-acceptance of certain colorants (certain forms of carbon black) and other concerns, continue tocause problems and delays. In addition, changes to existing products call into question previously approved devices and result in additional costs for testingand material analysis.After a product is placed on the market, the product and its manufacturer are subject to pervasive and continuing regulation by the FDA. The FDAenforces these requirements by inspection and market surveillance. Our suppliers also may be subject to FDA inspection; this has resulted in several suppliersaltering price structures for medical device companies. The additional costs due to testing and potential for lawsuits due to material contamination orunforeseen chemical/allergenic reactions has led to some manufacturers actively refusing to supply to medical device companies. The financial expenditureneeded to maintain compliance to the requirements of the FDA are extensive and ever increasing. Specific systems are needed to maintain compliance tobaseline requirements. In addition, complex systems are needed to ensure that specific violations such as ‘off label promotion’ are avoided. The FDA hasspecific requirements for labeling and marketing materials. These need extensive policing and evaluation. Penalties for breach of off label promotion canresult in significant fines to the company.The devices manufactured by us also are subject to the QSR, which imposes elaborate testing, control, documentation and other quality assuranceprocedures. Every phase of production, including raw materials, components and subassembly, manufacturing, testing, quality control, labeling, tracing ofconsignees after distribution and follow-up and reporting of complaint information is governed by the FDA’s QSR. Device manufacturers are required toregister their facilities and list their products with the FDA and certain state agencies. The FDA periodically inspects manufacturing facilities and, if there arealleged violations, the operator of a facility must correct them or satisfactorily demonstrate the absence of the violations or face regulatory action. Penaltiesfor failure to maintain compliance to the QSR include warning letters and potentially consent decrees. Failure to maintain the QSR appropriately could resultin the development of further warning letters. In addition, non-compliance with applicable FDA requirements can result in, among other things, fines,injunctions, civil penalties, recall or10seizure of products, total or partial suspension of production, failure of the FDA to grant marketing approvals, withdrawal of marketing approvals, arecommendation 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.Other U.S. Regulatory BodiesWe 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 disposalof hazardous or potentially hazardous substances. In addition, we are subject to various federal and state laws governing our relationships with the physiciansand 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 forany item payable under Medicare, Medicaid or any other federal healthcare program. Many states have similar laws. There can be no assurance that we willnot 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 amaterial adverse effect upon our ability to do business.International RegulationInternationally, all of our current products are considered medical devices under applicable regulatory regimes, and we anticipate that this will be true forall of our future products. Sales of medical devices are subject to regulatory requirements in many countries. The regulatory review process may vary greatlyfrom country to country. For example, the European Union has a dedicated set of regulations regarding medical devices, specifically regulating their design,manufacturing, clinical trials, labeling and adverse event reporting. Devices that comply with those requirements are entitled to bear a ConformitéEuropéenne, or CE Mark, indicating that the device conforms to the essential requirements of the applicable directives and can be commercially distributedin countries that are members of the European Union. Similar regulations are in place for Canada, Japan, China and most other countries.In some cases, we rely on our international distributors to obtain regulatory approvals, complete product registrations, comply with clinical trialrequirements and complete those steps that are customarily taken in the applicable jurisdictions.International 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 arebanned or deviate from lawful performance standards, are subject to FDA export requirements. Before exporting such products to a foreign country, we mustfirst comply with the FDA’s regulatory procedures for exporting unapproved devices.The process of obtaining approval to distribute medical products is costly and time-consuming in virtually all the major markets where we sell medicaldevices. We cannot assure that any new medical devices we develop will be approved in a timely or cost-effective manner or approved at all. There can be noassurance that new laws or regulations regarding the release or sale of medical devices will not delay or prevent sale of our current or future products.THIRD-PARTY REIMBURSEMENT AND ANTI-FRAUD AND CORRUPT PRACTICES REGULATIONUnited StatesThe delivery of our devices is subject to regulation by the Department of Health and Human Services (HHS) and comparable state and non-U.S. agenciesresponsible for reimbursement and regulation of health care items and services. U.S. laws and regulations are imposed primarily in connection with theMedicare and Medicaid programs, as well as the government’s interest in regulating the quality and cost of health care. Foreign governments also imposeregulations in connection with their health care reimbursement programs and the delivery of health care items and services.U.S. federal health care laws apply when we or customers submit claims for items or services that are reimbursed under Medicare, Medicaid, or otherfederally-funded health care programs. The principal U.S. federal laws include: (1) the Anti-kickback Statute which prohibits offers to pay or receiveremuneration of any kind for the purpose of including or rewarding referrals of items or services reimbursable by a federal health care program; (2) the FalseClaims Act which prohibits the submission of false or otherwise improper claims for payment to a federally-funded health care program, including claimsresulting from a violation of the Anti-kickback Statute; (3) the Stark law which prohibits physicians from referring Medicare or Medicaid patients to aprovider that bills these programs for the provision of certain designated health services if the physician (or a member of the physician’s immediate family)has a financial relationship with that provider; and (4) health care fraud statutes that prohibit false statements and improper claims to any third-party payer.There are often similar state false claims,11anti-kickback, and anti-self-referral and insurance laws that apply to state-funded Medicaid and other health care programs and private third-party payers. Inaddition, the U.S. Foreign Corrupt Practices Act (FCPA) can be used to prosecute companies in the U.S. for arrangements with physicians or other partiesoutside the U.S. if the physician or party is a government official of another country and the arrangement violates the law of that country.InternationalOur success in international markets will depend largely upon the availability of reimbursement from the third-party payors through which healthcareproviders are paid in those markets. Reimbursement and healthcare payment systems vary significantly by country. The main types of healthcare paymentsystems are government sponsored healthcare and private insurance. Reimbursement approval must be obtained individually in each country in which ourproducts are marketed. Outside the U.S., we generally rely on our distributors to obtain reimbursement approval in the countries in which they will sell ourproducts. There can be no assurance that reimbursement approvals will be received.INSURANCEOur product liability insurance coverage is limited to a maximum of $10 million per product liability claim and an annual aggregate policy limit of $10million, subject to a self-insured retention of $500,000 per occurrence and $2 million in the aggregate. The policy covers, subject to policy conditions andexclusions, claims of bodily injury and property damage from any product sold or manufactured by us.There is no assurance that this level of coverage is adequate. We may not be able to sustain or maintain this level of coverage and cannot assure you thatadequate insurance coverage will continue to be available on commercially reasonable terms, or at all. A successful product liability claim or other claimwith respect to uninsured or underinsured liabilities could have a material adverse effect on our business.ENVIRONMENTAL, HEALTH AND SAFETYWe are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluentdischarge, handling and disposal of certain hazardous and potentially hazardous substances used in connection with our operations. Our operations are alsosubject to laws and regulations related to occupational health and safety. We maintain safety, training and maintenance programs as part of our ongoingefforts to ensure compliance with applicable laws and regulations.Although we believe that we have complied with environmental, health and safety laws and regulations in all material respects and, to date, have notbeen 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 complywith environmental regulations in the future.EMPLOYEESAs of May 31, 2017, we had approximately 1,250 full time employees.

Information on our website or connected to our website is notincorporated by reference into this Annual Report on Form 10-K.14Item 1A.Risk Factors.In addition to the other information contained in this Annual Report on Form 10-K, the following risk factors should be considered carefully inevaluating the Company's business. Our financial and operating results are subject to a number of factors, many of which are not within our control. Thesefactors include those set forth below. Our business, financial condition or results of operations could be materially and adversely affected by any of theserisks. Additional risks not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition or results ofoperations.RISKS RELATED TO OUR BUSINESS Consolidation in the healthcare industry could have an adverse effect on our revenues and results of operations.Many healthcare industry companies, including medical device companies, are consolidating to create new companies with greater market power. Asthe healthcare industry consolidates, competition to provide goods and services to industry participants will become more intense. These industryparticipants may try to use their market power to negotiate price concessions or reductions for medical devices that incorporate components produced by us.If we are forced to reduce our prices because of consolidation in the healthcare industry, our revenues would decrease and our consolidated earnings,financial condition, or cash flow would suffer.We face intense competition in the medical device industry. We may be unable to compete effectively with respect to technological innovation and pricewhich may have an adverse effect on our revenues, financial condition or results of operations.The markets for our products are highly competitive, and we expect competition to continue to intensify. We may not be able to compete effectively,and we may lose market share to our competitors. Our primary device competitors include: Boston Scientific Corporation; Cook Medical; C.R. Bard; MedicalComponents, Inc. (Medcomp); TeleFlex Medical; Smiths Medical, a subsidiary of Smiths Group plc; Medtronic; Merit Medical; Terumo MedicalCorporation; Johnson and Johnson and Total Vein Systems. Many of our competitors have substantially greater:•financial and other resources to devote to product acquisitions, research and development, marketing and manufacturing;•variety of products;•technical capabilities;•history of developing and introducing new products;•patent portfolios that may present an obstacle to our conduct of business;•name recognition; and•distribution networks and in-house sales forces.Our competitors may succeed in developing technologies and products earlier, in obtaining patent protection or regulatory clearance earlier, or incommercializing new products or technologies more rapidly than us. Our competitors may also develop products and technologies that are superior to thosewe are developing or that otherwise could render our products obsolete or noncompetitive. In addition, we may face competition from providers of othermedical therapies, such as pharmaceutical companies, that may offer non-surgical therapies for conditions that are currently, or in the future, may be treatedusing our products. Our products are generally sold at higher prices than those of our competitors. However, in the current environment of managed care,which is characterized by economically motivated buyers, consolidation among healthcare providers, increased competition and declining reimbursementrates, we are increasingly being required to compete on the basis of price. If we are not able to compete effectively, our market share and revenues maydecline.We face intense competition from other companies, and our inability to continue to effectively develop, acquire and/or market new products andtechnologies could have a material adverse effect on our business, results of operations and/or financial condition.The medical device business is intensely competitive and is characterized by rapid technological change, frequent product introductions and evolvingcustomer requirements. Our customers consider many factors when choosing among products, including features and reliability, quality, technology, clinicalor economic outcomes, availability, price and services provided by the manufacturer. We face competition globally from a wide range of companies, some ofwhich may have greater resources than us, which may enable them to adapt faster than us to customer needs or changes in customer requirements. Productintroductions, alternative products or enhancements by competitors that provide better features, clinical outcomes or economic15value and/or offer lower pricing may make our products or proposed products obsolete or less competitive. In addition, the trend of consolidation in themedical device industry and among our customers could result in greater competition and pricing pressures.As a result, we engage in product development and improvement programs to maintain and improve our competitive position. These development andimprovement programs involve significant investment in research and development, clinical trials and regulatory approvals and may require more time thananticipated to bring such products to market. We may not, however, be successful in enhancing existing products or developing new products ortechnologies that will achieve regulatory approval, be developed or manufactured in a cost effective manner, obtain appropriate intellectual propertyprotection or receive market acceptance and we may be unable to recover all or a meaningful part of our investment in such products or technologies.Additionally, there can be no assurance that the size of the markets in which we compete will increase above existing levels or not decline, that we will beable to maintain, gain or regain market share or that we can compete effectively on the basis of price or that the number of procedures in which our productsare used will increase above existing levels or not decline.As part of our business strategy, we also pursue the acquisition of complementary businesses, technologies and products. We may not be able toidentify appropriate acquisition candidates, consummate transactions or obtain agreements with favorable terms. Further, once a business is acquired, anyinability to successfully integrate the business, decreases in customer loyalty or product orders, failure to retain and develop its workforce, failure to establishand maintain appropriate controls or unknown or contingent liabilities could adversely affect our ability to realize the anticipated benefits of anyacquisition. The integration of an acquired business, whether or not successful, requires significant efforts which may result in additional expenses and divertthe attention of our management and technical personnel from other projects. These transactions are inherently risky, and there can be no assurance that anypast or future transaction will be successful. If we fail to develop and successfully manufacture and launch new products, generate satisfactory clinical results,provide sufficient economic value, enhance existing products, or identify, acquire and integrate complementary businesses, technologies and products or ifwe experience a decrease in market size or market share or declines in average selling price or procedural volumes, or otherwise fail to compete effectively,our business, results of operations and/or financial condition could be adversely affected.If we do not maintain our reputation with interventional physicians, our growth will be limited and our business could be harmed.Physicians typically influence the medical device purchasing decisions of the hospitals and other healthcare institutions in which they practice.Consequently, our reputation with interventional physicians is critical to our continued growth. We believe that we have built a positive reputation based onthe quality of our products, our physician-driven product development efforts, our marketing and training efforts and our presence at medical societymeetings. Any actual or perceived diminution in the quality of our products, or our failure or inability to maintain these other efforts, could damage ourreputation with interventional physicians and cause our growth to be limited and our business to be harmed.If we fail to develop or market new products and enhance existing products, we could lose market share to our competitors and our results of operationscould suffer.The market for interventional devices is characterized by rapid technological change, new product introductions, technological improvements, changesin physician requirements and evolving industry standards. To be successful, we must continue to develop and commercialize new products and to enhanceversions of our existing products. Our products are technologically complex and require significant research, planning, design, development and testingbefore they may be marketed. This process generally takes at least 12 to 18 months from initial concept and may take up to several years. In addition, productlife cycles are relatively short because medical device manufacturers continually develop smaller, more effective and less expensive versions of existingdevices in response to physician demand.Our success in developing and commercializing new and enhanced versions of our products is affected by our ability to:•recruit engineers;•timely and accurately identify new market trends;•accurately assess customer needs;•minimize the time and costs required to obtain regulatory clearance or approval;•adopt competitive pricing;•timely manufacture and deliver products;•accurately predict and control costs associated with the development, manufacturing and support of our products; and16•anticipate and compete effectively with our competitors’ efforts.Market acceptance of our products depends in part on our ability to demonstrate that our products are cost-effective and easier to use, as well as offertechnological advantages. Additionally, we may experience design, manufacturing, marketing or other difficulties that could delay or prevent ourdevelopment, introduction or marketing of new products or new versions of our existing products. As a result of such difficulties and delays, our developmentexpenses may increase and, as a consequence, our results of operations could suffer.Development and sales of our products are dependent on a number of factors beyond our control, and our inability to make and complete research anddevelopment investments, enhance the product development process and be innovative to solve customer needs with respect to the respective products mayadversely affect our business, financial condition and results of operations.A significant aspect of our growth strategy is the continued market development of products including NanoKnife, AngioVac, Venacure EVLT andBioFlo products.There can be no guarantee that we will be able to develop and manufacture additional next generation or updated products on commercially favorableterms, or at all. NanoKnife and AngioVac are developing technologies and the inability of either of them to achieve clinical acceptance, as well as ourinability to generate meaningful clinical data to convince providers of the clinical and economic benefits of our BioFlo platform, could severely limit ourability to drive revenue growth.We currently have FDA 510(k) clearance to market NanoKnife products for soft tissue ablation. If we are not able to secure FDA approval to conductinvestigational device exemption (IDE) trials or marketing approval for additional or more specific indications, through 510(k) clearance, pre-marketapproval or otherwise, our ability to market our NanoKnife products will be restricted which may have an adverse effect on our business, financial conditionand results of operations.Undetected defects may increase our costs and impair the market acceptance of our products.Our products have occasionally contained, and may in the future contain, undetected defects. When these problems occur, we must divert the attentionof our engineering personnel to address them. There is no assurance that we will not incur warranty or repair costs, be subject to liability claims for damagesrelated to product defects, or experience manufacturing, shipping or other delays or interruptions as a result of these defects in the future. Our insurancepolicies may not provide sufficient protection should a claim be asserted. In addition, the occurrence of defects may result in significant customer relationsproblems and injury to our reputation, and may impair market acceptance of our products.We, our competitors or other third parties, may engage in clinical trials with respect to our products. The results of these trials may be unfavorable, orperceived as unfavorable by the market, and could have a material adverse effect on our business, financial condition or results of operations.Our products may be the subject of clinical trials conducted by us, our competitors or third parties for the purposes of obtaining regulatory clearances orto gather market data. Unfavorable or inconsistent clinical data from existing or future clinical trials conducted by us, by our competitors or by third parties,or the FDA's or the market's perception of this clinical data, may adversely impact our ability to obtain product approvals, our position in, and share of, themarkets in which we participate and our business, financial condition, results of operations or future prospects.If we are unable to convince customers that our products can improve the cost structure of their business, our revenue growth and profitability may bematerially adversely impacted.Worldwide initiatives to contain healthcare costs have led government and the private sector to enact cost containment efforts as a means ofmanaging the growth of health care utilization. Common techniques include policies on price regulation, competitive pricing, bidding and tender mechanics,coverage and payment, comparative effectiveness of therapies, technology assessments, and managed-care arrangements. These changes are causing themarketplace to put increased emphasis on the delivery of more cost-effective medical devices and therapies. Government programs, including Medicare andMedicaid, private health care insurance, and managed-care plans have attempted to control costs by limiting the amount of reimbursement they will pay forparticular procedures or treatments, tying reimbursement to outcomes, shifting to population health management, and other mechanisms designed toconstrain utilization and contain costs. Simultaneously, hospitals are redefining their role in health care delivery as many assume much more risk and controlof the total cost of patient care. To successfully make this transformation health systems are consolidating, purchasing or partnering with physicians, post-acute care providers, while also narrowing networks thus allowing greater control over outcomes. Today, many systems are17becoming ‘mini’ payer/provider organizations. These newly redesigned health systems are creating mechanisms such as value analysis and centralizedpurchasing functions that set pricing and in some cases limit the number of vendors that can participate in the purchasing program. Hospitals are alsoaligning interests with physicians through employment and other arrangements, such as gainsharing, where a hospital agrees with physicians to share anyrealized cost savings resulting from the physicians’ collective change in practice patterns such as standardization of devices where medically appropriate.This has created an increasing level of price sensitivity among customers for our products. Some third-party payers must also approve coverage and setreimbursement levels for new or innovative devices or therapies before they will reimburse health care providers who use the medical devices or therapies.Even though a new medical device may have been cleared for commercial distribution, we may find limited demand for the device until coverage andsufficient reimbursement levels have been obtained from governmental and private third-party payers. In addition, some private third-party payers requirethat certain procedures or that the use of certain products be authorized in advance as a condition of reimbursement. International examples of costcontainment initiatives and health care reforms advancing clinical outcomes as the key to market access are emerging in France, Germany, the Netherlandsand the UK. This new criteria can severely restrict coverage, reduce reimbursement and delay access to key markets with requirements for incremental clinicalbenefit and coverage with evidence development.Cost-containment efforts of group purchasing organizations could adversely affect our selling prices, financial position and results of operations.Many of our existing and potential customers have become members of group purchasing organizations, or GPOs, and integrated delivery network, orIDNs, in an effort to reduce costs. GPOs and IDNs negotiate pricing arrangements with healthcare product manufacturers and distributors and offer thenegotiated prices to affiliated hospitals and other members. GPOs and IDNs typically award contracts on a category-by-category basis through a competitivebidding process. Bids are generally solicited from multiple manufacturers with the intention of driving down pricing. Due to the highly competitive nature ofthe GPO and IDN contracting processes, we may not be able to obtain market prices for our products or obtain or maintain contract positions with major GPOsand IDNs, which could adversely impact our profitability. Also, sales through a GPO or IDN can be significant to our business and if we are unable to retaincontracts with our customers, or acquire additional contracts, our financial results may be negatively impacted.We are dependent on single and limited source suppliers which subjects our business and results of operations to risks of supplier business interruptions.We currently purchase significant amounts of several key products and product components from single and limited source suppliers and anticipatethat we will do so for future products as well. Any delays in delivery of or shortages in those or other products and components could interrupt and delaymanufacturing of our products and result in the cancellation of orders for our products. Any or all of these suppliers could discontinue the manufacture orsupply of these products and components at any time. Due to FDA and other business considerations, we may not be able to identify and integrate alternativesources of supply in a timely fashion or at all. Any transition to alternate suppliers may result in production delays and increased costs and may limit ourability to deliver products to our customers. Furthermore, if we are unable to identify alternative sources of supply, we would have to modify our products touse substitute components, which may cause delays in shipments, increased design and manufacturing costs and increased prices for our products.In addition, we purchase certain products as a distributor for the manufacturer of those products, including Asclera,. Operational, quality or regulatoryissues of the manufacturers of the products we distribute could constrain or interrupt the availability of those products or services. Any constraint orinterruption in the supply of finished products that we distribute could have a material adverse effect on our ability to sell products, our financial conditionand our results of operations.We are heavily dependent on third-party distributors to generate a substantial portion of international revenues and are at the risk of these distributorsalso selling for our competitors along with being financially viable to be able to effectively distribute our products and make timely payment.Outside of the U.S we rely heavily on third party distributors, either on a country-by-country basis or on a multi-country, regional basis, to market, selland distribute our products. International distributors accounted for approximately 72% revenues for the year ended May 31, 2017. In certain circumstances,distributors may also sell competing products to our own or products for competing diagnostic modalities and may have incentives to shift sales towardsthose competing products. As a result, we cannot assure you that our international distributors will increase or maintain our current levels of unit sales orincrease or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, results of operations, financial conditionand cash flows. In addition, there is a risk that our distributors will not be financially viable due to current economic and/or regulatory events in theirrespective countries.18Failure to secure adequate reimbursement for our products could materially impair our ability to grow revenue and drive profitability.Our products are used in medical procedures generally covered by government or private health plans.In general, a third-party payor only covers a medical product or procedure when the plan administrator is satisfied that the product or procedureimproves health outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance orapproval for marketing by the FDA, there is no assurance that third-party payors will cover the cost of the device and related procedures.In many instances, third-party payors use price schedules that do not vary to reflect the cost of the products and equipment used in performing thoseprocedures. In other instances, payment or reimbursement is separately available for the products and equipment used, in addition to payment orreimbursement for the procedure itself. Even if coverage is available, third-party payors may place restrictions on the circumstances where they providecoverage or may offer reimbursement that is not sufficient to cover the cost of our products.Third-party payors who cover the cost of medical products or equipment, in addition to allowing a general charge for the procedure, often maintain listsof exclusive suppliers or approved lists of products deemed to be cost-effective. Authorization from those third-party payors is required prior to usingproducts that are not on these lists as a condition of reimbursement. If our products are not on the approved lists, healthcare providers must determine if theadditional cost and effort required in obtaining prior authorization, and the uncertainty of actually obtaining coverage, is justified by any perceived clinicalbenefits from using our products.Finally, the advent of contracted fixed rates per procedure has made it difficult to receive reimbursement for disposable products, even if the use ofthese products improves clinical outcomes. In addition, many third-party payors are moving to managed care systems in which providers contract to providecomprehensive healthcare for a fixed cost per person. Managed care providers often attempt to control the cost of healthcare by authorizing fewer electivesurgical procedures. Under current prospective payment systems, such as the diagnosis related group system and the hospital out-patient prospective paymentsystem, both of which are used by Medicare and in many managed care systems used by private third-party payors, the cost of our products will beincorporated into the overall cost of a procedure and not be separately reimbursed. As a result, we cannot be certain that hospital administrators andphysicians will purchase our products, despite the clinical benefits and opportunity for cost savings that we believe can be derived from their use. If hospitalsand physicians cannot obtain adequate reimbursement for our products or the procedures in which they are used, our business, financial condition, results ofoperations, and cash flows could suffer a material adverse impact.Our success in international markets will depend largely upon the availability of reimbursement from the third-party payors through which healthcareproviders are paid in those markets. Reimbursement and healthcare payment systems vary significantly by country. The main types of healthcare paymentsystems are government sponsored healthcare and private insurance. Reimbursement approval must be obtained individually in each country in which ourproducts are marketed. Outside the United States, we generally rely on our distributors to obtain reimbursement approval in the countries in which they willsell our products. There can be no assurance that reimbursement approvals will be received. The failure to secure reimbursement approvals in internationalmarkets could materially impact our financial position and results of operations.If a product liability claim is brought against us or our product liability insurance coverage is inadequate, our business could be harmed.The design, manufacture and marketing of the types of medical devices we sell entail an inherent risk of product liability. Our products are used byphysicians to treat seriously ill patients. We are periodically subject to product liability claims, and patients or customers may in the future bring claimsagainst us in a number of circumstances and for a number of reasons, including if our products were misused, if a component of our product fails, if theirmanufacture or design was flawed, if they produced unsatisfactory results or if the instructions for use and operating manuals and disclosure of productrelated risks for our products were found to be inadequate. In addition, individuals or groups seeking to represent a class may file suit against us. Theoutcome of litigation, particularly class action lawsuits, is difficult to assess or quantify. Plaintiffs in these types of lawsuits often seek recovery of very largeor indeterminate amounts, including not only actual damages, but also punitive damages. The magnitude of the potential losses relating to these lawsuitsmay remain unknown for substantial periods of time.We carry a product liability policy with a limit of $10,000,000 per product liability claim and an aggregate policy limit of $10,000,000, subject to aself-insured retention of $500,000 per occurrence and $2,000,000 in the aggregate. We believe, based on claims made against us in the past, our existingproduct liability insurance coverage is reasonably adequate to protect us19from any liabilities we might incur. However, there is no assurance that this coverage will be sufficient to satisfy any claim made against us. In addition, wemay not be able to continue to maintain adequate coverage at a reasonable cost and on reasonable terms, if at all. Any product liability claim brought againstus, with or without merit, could increase our product liability insurance rates or prevent us from securing any coverage in the future. Additionally, if one ormore product liability claims is brought against us for uninsured liabilities or is in excess of our insurance coverage, our financial condition and results ofoperations could be negatively impacted. Further, such claims may require us to recall some of our products, which could result in significant costs to us andcould divert management’s attention from our business.We may be exposed to risks associated with acquisitions, including integration risks and risks associated with methods of financing and the impact ofaccounting treatment. Accordingly, completed acquisitions may not enhance our financial position or results of operations as they are based projectionsand assumptions which are uncertain and subject to change.Part of our growth strategy is to acquire businesses and technologies that are complementary to ours. There is no assurance that acquisitionopportunities will be available on acceptable terms, or at all, or that we will be able to obtain necessary financing or regulatory approvals. Any acquisitionsthat we do undertake would be accompanied by the risks commonly encountered in acquisitions, including the:•potential disruption of our business while we evaluate opportunities, complete acquisitions and develop and implement new business strategiesto take advantage of these opportunities;•inability of our management to maximize our financial and strategic position by incorporating an acquired technology or business into ourexisting offerings;•our inability to achieve the cost savings and operating synergies anticipated in the acquisition, which would prevent us from achieving thepositive earnings gains expected as a result of the acquisition;•diversion of management attention from ongoing business concerns to integration matters;•difficulty of maintaining uniform standards, controls, procedures and policies;•challenges in demonstrating to our customers that the acquisition will not result in adverse changes in customer service standards or businessfocus;•possible cash flow interruption or loss of revenue as a result of change of ownership transitional matters;•difficulty of assimilating the operations and personnel of acquired businesses;•potential loss of key employees of acquired businesses, and the impairment of relationships with employees and customers as a result of changesin management; and•uncertainty as to the long-term success of any acquisitions we may make including the impact on contingent liabilities.There is no assurance that any completed acquisition will be accretive to our margins or profits in the short term or in the long term. If we proceed withone or more significant acquisitions in which the consideration consists of cash, a substantial portion of our available cash could be used to consummate theacquisitions. If we consummate one or more acquisitions in which the consideration consists of capital stock, our stockholders could suffer significantdilution of their interest in us. In addition, we could incur or assume significant amounts of indebtedness in connection with acquisitions. Further,acquisitions could also result in significant goodwill and/or amortization charges for acquired businesses or technologies.Failure to attract additional capital which we may require to expand our business could curtail our growth.We may require additional capital to expand our business. If cash generated internally is insufficient to fund capital requirements, we will requireadditional debt or equity financing. In addition, we may require financing to fund any significant acquisitions we may seek to make. Needed financing maynot be available or, if available, may not be available on terms satisfactory to us and may result in significant stockholder dilution. Covenants in our existingfinancing agreements may also restrict our ability to obtain additional debt financing. If we fail to obtain sufficient additional capital in the future, we couldbe forced to curtail our growth strategy by reducing or delaying capital expenditures and acquisitions, selling assets, restructuring our operations orrefinancing our indebtedness.International and national economic and industry conditions constantly change, and could materially and adversely affect our business, financialcondition and results of operations.Our business, financial condition and results of operation are affected by many changing economic, industry and other conditions beyond our control.Actual or potential changes in international, national, regional and local economic, business and financial conditions, including recession, inflation andtrade protection measures, may negatively affect consumer preferences, perceptions, spending patterns or demographic trends, any of which could adverselyaffect our business, financial condition or results of operations. Our customers may experience financial difficulties or be unable to borrow money to fundtheir20operations, which may adversely impact their ability or decision to purchase or pay for our products. Disruptions in the credit markets have previouslyresulted, and could again result, in volatility, decreased liquidity, widening of credit spreads, and reduced availability of financing. There can be noassurance that future financing will be available to us on acceptable terms, if at all. An inability to obtain necessary additional financing on acceptable termsmay have an adverse impact on us and on our ability to execute on our business plan.We are subject to a variety of market and financial risks due to our international operations that could adversely affect those operations or ourprofitability and operating results.Although our stock is traded on the New York Stock Exchange, we are a global Company. Operations in countries outside of the U.S., which account forapproximately 19% percent of our net sales for the fiscal year ended May 31, 2017, are accompanied by certain financial and other risks that would not befaced by a Company operating purely within the U.S. We intend to continue to pursue growth opportunities in sales outside the U.S., especially in emergingmarkets, which could expose us to greater risks associated with international sales and operations. Our profitability and international operations are, and willcontinue to be, subject to a number of risks and potential costs, including:•fluctuations in currency exchange rates;•healthcare reform legislation;•multiple non-U.S. regulatory requirement that are subject to change and that could restrict our ability to manufacture and sell our products;•local product preferences and product requirements;•longer-term receivables than are typical in the U.S.;•trade protection measures and import or export licensing requirements;•less intellectual property protection in some countries outside the U.S. than exists in the U.S.;•different labor regulations and workforce instability;•political instability;•the potential payment of U.S. income taxes on earnings of certain foreign subsidiaries subject to U.S. taxation upon repatriation;•the expiration and non-renewal of foreign tax rulings;•potentially negative consequences from changes in or interpretation of tax laws; and•economic instability and inflation, recession or interest rate fluctuations.There are recent legislative proposals to tax profits of U.S. affiliates which are earned abroad. While it is impossible for us to predict whether these andother proposals will be implemented, or how they will ultimately impact us, they may materially impact our results of operations if, for example, our profitsearned abroad are subject to U.S. income tax, or we are otherwise disallowed deductions as a result of these profits.On June 23, 2016, the United Kingdom (U.K.) held a referendum in which voters approved an exit from the E.U., commonly referred to as “Brexit”. As aresult of the referendum, it is expected that the British government will begin negotiating the terms of the U.K.’s future relationship with the E.U. Although itis unknown what those terms will be, it is possible that there will be greater restrictions on imports and exports between the U.K. and E.U. countries andincreased regulatory complexities. These changes may adversely affect our operations and financial results.Finally, changes in currency exchange rates may reduce the reported value of our revenues outside the U.S, net of expenses, and cash flows. We cannotpredict changes in currency exchange rates, the impact of exchange rate changes, nor the degree to which we will be able to manage the impact of currencyexchange rate changes.Continuing worldwide economic instability, including challenges faced by the Eurozone countries, could adversely affect our revenues, financial conditionor results of operations.Since fiscal year 2008, the global economy has been impacted by the sequential effects of an ongoing global financial crisis. There can be no assurancethat there will not be further deterioration in the global economy. Our customers and vendors may experience financial difficulties or be unable to borrowmoney to fund their operations which may adversely impact their ability to purchase our products or to pay for our products on a timely basis, if at all. Aswith our customers and vendors, these economic conditions make it more difficult for us to accurately forecast and plan our future business activities. Inaddition, trade receivables are in many countries (including, but not limited to, Greece, Ireland, Portugal, and Spain). Repayment of these receivables isdependent upon the financial stability of the economies of those countries.21In light of these global economic fluctuations, we continue to monitor the creditworthiness of customers located outside the U.S. Failure to receivepayment of all or a significant portion of these receivables could adversely affect our results of operations. Further, there are concerns for the overall stabilityand suitability of the Euro as a single currency, given the economic and political challenges facing individual Eurozone countries. Continuing deteriorationin the creditworthiness of the Eurozone countries, the withdrawal of one or more member countries from the EU, or the failure of the Euro as a commonEuropean currency could adversely affect our revenues, financial condition or results of operations.Our business could be harmed if we lose the services of our key personnel.Our business depends upon our ability to attract and retain highly qualified personnel, including managerial, sales and technical personnel. Wecompete for key personnel with other companies, healthcare institutions, academic institutions, government entities and other organizations. We do not havewritten employment agreements with our executive officers, other than the CEO. Our ability to maintain and expand our business may be impaired if we areunable to retain our current key personnel or hire or retain other qualified personnel in the future. In addition, our sales force is highly talented and there ishigh competition in the sales industry which could have an adverse effect on our business if there is significant turnover.RISKS RELATED TO OPERATIONSIf we are unable to manage our growth profitably, our business, financial results and stock price could suffer.Our future financial results will depend in part on our ability to profitably manage our growth. Management will need to maintain existing customersand attract new customers, recruit, retain and effectively manage employees, as well as expand operations and integrate customer support and financialcontrol systems. If integration-related expenses and capital expenditure requirements are greater than anticipated or if we are unable to manage our growthprofitably, our financial results and the market price of our common stock may decline.In recent years we have begun to implement our operational excellence initiatives which include a number of restructuring, realignment and costreduction initiatives. While we have realized some efficiencies from these actions, we may not realize the benefits of these initiatives to the extent weanticipated. Further, such benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be greater thananticipated, which could cause us to incur additional costs or result in business disruptions. In addition, if these measures are not successful or sustainable, wemay undertake additional realignment and cost reduction efforts, which could result in significant additional charges. Moreover, if our restructuring andrealignment efforts prove ineffective, our ability to achieve our other strategic goals and business plans may be adversely affected.We have incurred significant indebtedness which imposes operating and financial restrictions on us which, together with our debt service obligations,could significantly limit our ability to execute our business strategy and increase the risk of default under our debt obligations.We borrowed an aggregate of approximately $97.5 million as of May 31, 2017. The interest rate on these borrowings is a floating rate which couldexpose us to the risk of increased interest expense in the future. The terms of our credit facilities require us to comply with certain financial maintenancecovenants. In addition, the terms of our indebtedness also include certain covenants restricting or limiting our ability to take certain actions.These covenants may adversely affect our ability to finance future operations or limit our ability to pursue certain business opportunities or take certaincorporate actions. The covenants may also restrict our flexibility in planning for changes in our business and the industry and make us more vulnerable toeconomic downturns and adverse developments.Our ability to meet our cash requirements, including our debt service obligations, will be dependent upon our operating performance, which will besubject to general economic and competitive conditions and to financial, business and other factors affecting our operations, many of which are or may bebeyond our control. We cannot provide assurance that our business operations will generate sufficient cash flows from operations to fund these cashrequirements and debt service obligations. If our operating results, cash flow or capital resources prove inadequate, we could face substantial liquidityproblems and might be required to dispose of material assets or operations to meet our debt and other obligations. If we are unable to service our debt, wecould be forced to reduce or delay planned expansions and capital expenditures, sell assets, restructure or refinance our debt or seek additional equity capital,and we may be unable to take any of these actions on satisfactory terms or in a timely manner. Further, any of these actions may not be sufficient to allow usto service our debt obligations or may have an adverse impact on our business. Our debt agreements limit our ability to take certain of these actions. Ourfailure to generate sufficient22operating cash flow to pay our debts or to successfully undertake any of these actions could have a material adverse effect on us.In addition, the degree to which we are leveraged as a result of the indebtedness incurred in connection with an acquisition or otherwise couldmaterially and adversely affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements orother purposes, could make us more vulnerable to general adverse economic, regulatory and industry conditions, could limit our flexibility in planning for,or reacting to, changes and opportunities in the markets in which we compete, could place us at a competitive disadvantage compared to our competitors thathave less debt or could require us to dedicate a substantial portion of our cash flow to service our debt.Despite our substantial indebtedness, we may incur more debt, which could exacerbate the risks described above.We may be able to incur substantial additional indebtedness in the future subject to the limitations contained in the agreements governing our debt.Although these agreements restrict us from incurring additional indebtedness, these restrictions are subject to important exceptions and qualifications. Forexample, we are generally permitted to incur certain indebtedness, including indebtedness arising in the ordinary course of business and indebtednessrelating to acquisition activities. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and CapitalResources” If we incur additional debt, the risks that we and they now face as a result of our higher leverage could intensify.Our international sales and operations are subject to risks and uncertainties that vary by country and which could have a material adverse effect on ourbusiness and/or results of operations.Sales outside the United States accounted for approximately 19% of our net sales during our fiscal year ended May 31, 2017. We anticipate that salesfrom international operations will continue to represent a significant portion of our total sales, and we intend to continue our expansion into emerging and/orfaster-growing markets outside the United States. Our sales and profitability from our international operations are subject to risks and uncertainties that canvary by country, and include those related to political and economic conditions, foreign currency exchange rate fluctuations, changes in tax laws, regulatoryand reimbursement programs and policies, and the protection of intellectual property rights. These risks and uncertainties could have a material adverse effecton our business and/or results of operations.Foreign currency exchange rate may adversely affect our business, financial condition and results of operations.We are exposed to a variety of market risks, including the effects of changes in foreign currency exchange rates. Products manufactured in, and soldinto, foreign markets represent a significant portion of our operations. When the United States dollar strengthens or weakens in relation to the foreigncurrencies of the countries in which we sell or manufacture our products, such as the euro, our United States dollar-reported revenue and income willfluctuate. As a result of the June 23, 2016 referendum by British voters to exit the European Union, global markets and foreign currencies have beenadversely impacted and the value of the Pound Sterling has sharply declined as compared to the U.S. Dollar and other currencies. This volatility in foreigncurrencies is expected to continue as the U.K. negotiates and executes its exit from the European Union but it is uncertain over what time period this willoccur. The effects of currency rate fluctuations and changes in the relative values of currencies may, in some instances, have a significant effect on ourbusiness, financial condition, results of operations and cash flows.Our goodwill, intangible assets and fixed assets are subject to potential impairment.A significant portion of our assets consists of goodwill, intangible assets and fixed assets, the carrying value of which may be reduced if we determinethat those assets are impaired.Most of our intangible and fixed assets have finite useful lives and are amortized or depreciated over their useful lives on either a straight-line basis orover the expected period of benefit or as revenues are earned from the sales of the related products. The underlying assumptions regarding the estimateduseful lives of these intangible assets are reviewed annually and more often if an event or circumstance occurs making it likely that the carrying value of theassets may not be recoverable and are adjusted through accelerated amortization if necessary. Whenever events or changes in circumstances indicate that thecarrying value of the assets is not recoverable we test intangible assets for impairment based on estimates of future cash flows. If an intangible asset isconsidered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset.We review our single reporting unit for potential goodwill impairment in the third fiscal quarter of each year as part of our annual goodwill impairmenttesting, and more often if an event or circumstance occurs making it likely that impairment exists. We conduct impairment testing based on our currentbusiness strategy in light of present industry and economic23conditions, as well as future expectations. The annual goodwill impairment review performed in December 2016 indicated no goodwill impairments.If actual results differ from the assumptions and estimates used in the goodwill and intangible asset calculations, we could incur future impairment oramortization charges, which could negatively impact our results of operations.We may be limited in our ability to utilize, or may not be able to utilize, net operating loss carryforwards to reduce our future tax liability.IRC Section 382 and related provisions contain rules that limit for U.S. federal income tax purposes the ability of a Company that undergoes an“ownership change” to utilize its net operating loss carryforwards and certain other tax attributes existing as of the date of such ownership change. OurFederal net operating loss carryforwards as of May 31, 2017 after considering IRC Section 382 limitations are $161.6 million. The expiration of the Federalnet operating loss carryforwards is as follows: $29.8 million between 2017 and 2023 and $131.8 million between 2027 and 2037. Our state net operatingloss carryforwards as of May 31, 2017 after considering remaining IRC Section 382 limitations are $32.7 million which expire in various years from 2017 to2037. Future ownership changes within the meaning of IRC Section 382 may also subject our tax loss carryforwards to annual limitations which wouldrestrict our ability to use them to offset our taxable income in periods following the ownership changes. See Note 9 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended May 31, 2017 for a furtherdiscussion of our tax loss carryovers.Fluctuations in our effective tax rate and changes to tax laws may adversely affect us.As an international Company, we are subject to taxation in numerous countries, states and other jurisdictions. Our effective tax rate is derived from acombination of applicable tax rates in the various countries, states and other jurisdictions in which we operate. In preparing our financial statements, weestimate the amount of tax that will become payable in each of these jurisdictions. Our effective tax rate may, however, differ from the estimated amount dueto numerous factors, including a change in the mix of our profitability from country to country and changes in tax laws. Any of these factors could cause us toexperience an effective tax rate significantly different from previous periods or our current expectations, which could have an adverse effect on our business,financial condition and results of operations and cash flows.We rely on the proper function, availability and security of information technology systems to operate our business and a cyber-attack or other breach ofthese systems could have a material adverse effect on our business, financial condition or results of operations.We rely on information technology systems to process, transmit, and store electronic information in our day-to-day operations. Similar to other largemulti-national companies, the size and complexity of our information technology systems makes them vulnerable to a cyber-attack, malicious intrusion,breakdown, destruction, loss of data privacy, or other significant disruption. Our information systems require an ongoing commitment of significant resourcesto maintain, protect, and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology,evolving systems and regulatory standards, the increasing need to protect patient and customer information, and changing customer patterns. In addition,third parties may attempt to hack into our products to obtain data relating to patients with our products or our proprietary information. Any failure by us tomaintain or protect our information technology systems and data integrity, including from cyber-attacks, intrusions or other breaches, could result in theunauthorized access to patient data and personally identifiable information, theft of intellectual property or other misappropriation of assets, or otherwisecompromise our confidential or proprietary information and disrupt our operations. Any of these events, in turn, may cause us to lose existing customers,have difficulty preventing, detecting, and controlling fraud, have disputes with customers, physicians, and other health care professionals, be subject to legalclaims and liability, have regulatory sanctions or penalties imposed, have increases in operating expenses, incur expenses or lose revenues as a result of adata privacy breach or theft of intellectual property, or suffer other adverse consequences, any of which could have a material adverse effect on our business,financial condition or results of operations.Any disaster at our manufacturing facilities could disrupt our ability to manufacture our products for a substantial amount of time, which could cause ourrevenues to decrease. This risk is more significant as we consolidate our plants in fiscal year 2018.We conduct our manufacturing and assembly at facilities in Queensbury, New York, Glens Falls, New York, Manchester, Georgia, and Denmead,England. It would be difficult, expensive and time-consuming to transfer resources from one facility to24the other, replace, or repair these facilities and our manufacturing equipment if they were significantly affected by a disaster. Additionally, we might beforced to rely on third-party manufacturers or to delay production of our products. Insurance for damage to our properties and the disruption of our businessfrom disasters may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. In addition, ifone of our principal suppliers were to experience a similar disaster, uninsured loss or under-insured loss, we might not be able to obtain adequate alternativesources of supplies or products or could face significant delays and incur substantial expense in doing so. Any significant uninsured loss, prolonged orrepeated disruption, or inability to operate experienced by us or any of our principal suppliers could cause significant harm to our business, financialcondition and results of operations.Once the plant consolidation is complete, manufacturing and assembly will only take place in Queensbury, New York and Glens Falls, New York. If wewere significantly affected by a disaster, we no longer have an option to transfer manufacturing to another facility so we would be forced to rely on third-party manufacturers or would have to delay production of our products.Anti-takeover provisions in our organizational documents and Delaware law may discourage or prevent a change of control, even if an acquisition wouldbe beneficial to our stockholders, which could cause our stock price to decline and prevent attempts by our stockholders to replace or remove our currentmanagement.Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that may enable our management toresist a change in control. These provisions may discourage, delay or prevent a change in the ownership of our Company or a change in our management. Inaddition, these provisions could limit the price that investors would be willing to pay in the future for shares of our common stock. Such provisions include:•our board of directors is authorized, without prior stockholder approval, to create and issue “blank check” preferred stock, with rights senior tothose of our common stock;•our board of directors is classified so that not all members of our board of directors are elected at one time, which may make it more difficult fora person who acquires control of a majority of our outstanding voting stock to replace our directors;•advance notice requirements for stockholders to nominate individuals to serve on our board of directors or for stockholders to submit proposalsthat can be acted upon at stockholder meetings;•stockholder action by written consent is prohibited; and•stockholders are not permitted to cumulatively vote for the election of directors.We are also subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business combinations withstockholders owning 15% or more of our outstanding voting stock.These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it moredifficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by our then-current board ofdirectors, including delaying or impeding a merger, tender offer or proxy contest involving our Company. Any delay or prevention of a change of controltransaction or changes in our board of directors could cause the market price of our common stock to decline.RISKS RELATED TO THE REGULATORY ENVIRONMENTReforms to the United States healthcare system may adversely affect our business.A significant portion of our patient volume is derived from U.S. government healthcare programs, principally Medicare, which are highly regulated andsubject to frequent and substantial changes. For example, in March 2010, the President signed one of the most significant healthcare reform measures indecades, the Healthcare Reform Act. The Healthcare Reform Act contains a number of provisions that affect coverage and reimbursement of drug productsand medical imaging procedures in which our drug products are used. See “Business-Regulatory Matters-Healthcare Reform Act and Related Laws.” Wecannot assure you that the Healthcare Reform Act, as currently enacted or as amended in the future, will not adversely affect our business and financialresults, and we cannot predict how future federal or state legislative, judicial or administrative changes relating to healthcare reform will affect our business.In addition, other legislative changes have been proposed and adopted since the Healthcare Reform Act was enacted. The Budget Control Act of 2011includes provisions to reduce the federal deficit. The Budget Control Act, as amended, resulted in the imposition of 2% reductions in Medicare payments toproviders, which went into effect on April 1, 2013 and will remain in effect through 2024 unless additional Congressional action is taken. Any significantspending reductions affecting Medicare,25Medicaid or other publicly funded or subsidized health programs that may be implemented and/or any significant taxes or fees that may be imposed on us, aspart of any broader deficit reduction effort or legislative replacement to the Budget Control Act, could have an adverse impact on our results of operations.In addition, federal spending is also subject to a statutory debt ceiling. If the federal debt reaches the statutory debt ceiling, Congress must enactlegislation to suspend enforcement of, or increase, the statutory debt ceiling. If Congress fails to do so before the ceiling is reached and, as a result, is unableto satisfy its financial obligations, including under Medicare, Medicaid and other publicly funded or subsidized health programs, our results of operationscould be adversely impacted.The full impact on our business of the Healthcare Reform Act and the other new laws is uncertain. Nor is it clear whether other legislative changes willbe adopted or how those changes would affect our industry generally or our ability to successfully commercialize our products or the development of newproducts.Under the statutory Medicare sustainable growth rate formula, payments under the Medicare Physician Fee Schedule could have decreasedsignificantly over the past several years without congressional intervention. In the past, when the application of the statutory formula would have resulted inlower payments, Congress has passed interim legislation to prevent the reductions. In 2014, Congress again prevented the negative update factor from goinginto effect until March 31, 2015. If Congress fails to intervene to prevent the negative update factor in the future through either another temporary measure ora permanent revision to the statutory formula, payments to physicians may be reduced.Our industry is experiencing greater scrutiny and regulation by governmental authorities, which has led to certain costs and business distractions as werespond to inquiries and comply with new regulations, and may lead to greater governmental regulation in the future.Our medical devices and our business activities are subject to rigorous regulation by the FDA and numerous other federal, state and foreigngovernmental authorities. These authorities and members of Congress have been increasing their scrutiny of our industry. In addition, certain states,including Massachusetts, have recently passed or are considering legislation restricting our interactions with health care providers and requiring disclosure ofmany payments to them. The federal government has recently introduced similar legislation, which may or may not preempt state laws. Recent SupremeCourt case law has clarified that the FDA’s authority over medical devices preempts state tort laws, but legislation has been introduced at the federal level toallow state intervention, which could lead to increased and inconsistent regulation at the state level. We anticipate that the government will continue toscrutinize our industry closely, and that additional regulation by governmental authorities may increase compliance costs, exposure to litigation and otheradverse effects to our operations.We are subject to a comprehensive system of federal, state and international laws and regulations, and we could be the subject of investigations,enforcement actions or face lawsuits and monetary or equitable judgments.We operate in many parts of the world, and our operations are affected by complex state, federal and international laws relating to healthcare,environmental protection, antitrust, anti-corruption, anti-bribery, fraud and abuse, export control, tax, employment and laws regarding privacy, personallyidentifiable information and protected health information, including, for example, the Food, Drug and Cosmetic Act (“FDCA”), various FDA andinternational regulations relating to, among other things, the development, quality assurance, manufacturing, importation, distribution, marketing and saleof, and billing for, our products, the federal Anti-Kickback Statute and Federal False Claims Act, the U.S. Foreign Corrupt Practices Act (“FCPA”), the UKBribery Act of 2010, the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and other foreign data protection and privacy laws,and laws and regulations relating to sanctions and money laundering. We are subject to periodic inspections to determine compliance with the FDA’s QualitySystem Regulation requirements, current medical device adverse event reporting regulations, and similar foreign rules and regulations. Despite our trainingand compliance programs, our internal control policies and procedures may not always protect us from negligent, reckless or criminal acts committed by ouremployees or agents. The failure to comply with these laws and regulatory standards, allegations of such non-compliance or the discovery of previouslyunknown problems with a product or manufacturer: (i) could result in FDA Form-483 notices and/or warning letters or the foreign equivalent, fines, delays orsuspensions of regulatory clearances, investigations, detainment, seizures or recalls of products (with the attendant expenses), the banning of a particulardevice, an order to replace or refund the cost of any device previously manufactured or distributed, operating restrictions and/or civil or criminal prosecution,and/or penalties, as well as decreased sales as a result of negative publicity and product liability claims; and (ii) could disrupt our business and could have amaterial adverse effect on our business, results of operations, financial condition and/or liquidity.Most of our products must receive clearance or approval from the FDA or comparable regulatory agencies abroad before they can be marketed or sold.State, federal and foreign registration regulations are both evolving and subject to varied levels of26interpretation and enforcement. It can be costly and time-consuming to obtain and maintain regulatory approvals to market a medical device. Approvalsmight not be granted on a timely basis, if at all, for new devices, new indications for use or certain modifications or enhancements to previously approvedproducts. Even after a device receives regulatory approval it remains subject to significant regulatory and quality requirements, such as manufacturing,recordkeeping, renewal, recertification or reporting and other post market approval requirements, which may include clinical, laboratory or other studies.Product approvals by the FDA and other foreign regulators can be withdrawn due to failure to comply with regulatory standards or the occurrence ofunforeseen problems following initial approval or may be re-classified to a higher regulatory classification, such as requiring a Pre-Market Approval (“PMA”)for a previously cleared 510(k) device. Regulations are also subject to change as a result of legislative, administrative or judicial action, which may furtherincrease our costs or reduce sales. Our failure to maintain approvals, obtain approval for new products or comply with other applicable regulatoryrequirements could adversely affect our business, results of operations, financial condition and/or liquidity.The healthcare industry is under continued scrutiny from state, federal and international governments with respect to industry practices in the area ofsales and marketing, including provisions of the Physician Payment Sunshine Act. If our marketing, sales or other activities fail to comply with the FDA’s orother comparable foreign regulatory agencies’ regulations or guidelines, or other applicable laws, we may be subject to warnings from the FDA orinvestigations or enforcement actions from the FDA, Medicare, the Office of Inspector General of the U.S. Department of Health and Human Services or othergovernment agencies or enforcement bodies. Additionally, in the European Union, a new draft Medical Device Regulation was published in 2016 imposingstricter requirements for the marketing and sale of medical devices and grants Notified Bodies increased post-market surveillance authority. The Company ismonitoring the implementation of the regulation and has undertaken initial actions to move toward compliance based on the published draft of theregulation. The Company’s failure to comply with any marketing or sales regulations or any other applicable regulatory requirements could adversely affectour business, results of operations, financial condition and/or liquidity.In the recent past, medical device manufacturers have been the subject of investigations from government agencies related to their relationships withdoctors, product sales and marketing and off-label promotion of products, among other activities or practices. If an enforcement action involving theCompany were to occur, it could result in penalties, fines, detainment, seizures, recalls, product bans, operating restrictions (which may include loss of alicense or authorization), the exclusion of our products from reimbursement under government-funded programs and/or prohibitions on our ability to sell ourproducts, and could have a material adverse effect on our business, results of operations, financial condition and/or liquidity. In addition, remediation of anyissues identified by the FDA or other regulators could require facility upgrades, process changes, additional labeling requirements or other measures, any ofwhich could have a material adverse effect on our business and/or results of operations. See Item 3. “Legal Proceedings” below for a description of thesubpoenas and Civil Investigation Demands from a number of State Attorneys General and investigative subpoena from the Department of Defense, in eachcase, seeking information related to certain of the Company’s products.In addition, lawsuits by or otherwise involving employees, customers, licensors, licensees, suppliers, vendors, business partners, distributors,shareholders or competitors with respect to how we conduct our business could be very costly and could substantially disrupt our business. Disputes fromtime-to-time with companies or individuals are not uncommon, and we cannot assure you that we will be able to resolve these disputes on terms favorable tous. See Item 3. “Legal Proceedings” below for a description of lawsuits against the Company. The occurrence of an adverse monetary or equitable judgmentor a large expenditure in connection with a settlement of any of these matters could have a material adverse effect on our business, results of operations,financial condition and/or liquidity.We are subject to healthcare fraud and abuse regulations that could result in significant liability, require us to change our business practices and restrictour operations in the future.We are subject to various federal, state and local laws targeting fraud and abuse in the healthcare industry, including anti-kickback and false claimslaws. Violations of these laws are punishable by criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation inhealthcare programs such as Medicare and Medicaid and health programs outside the United States. These laws and regulations are wide ranging and subjectto changing interpretation and application, which could restrict our sales or marketing practices. Furthermore, since many of our customers rely onreimbursement from Medicare, Medicaid and other governmental programs to cover a substantial portion of their expenditures, our exclusion from suchprograms as a result of a violation of these laws could have a material adverse effect on our business, results of operations, financial condition and cash flow.27If we or some of our suppliers fail to comply with the FDA’s Quality System Regulation, or QSR, and other applicable postmarket requirements, ourmanufacturing operations could be disrupted, our product sales and profitability could suffer, and we may be subject to a wide variety of FDA enforcementactions.After a device is placed on the market, numerous regulatory requirements apply. We are subject to inspection and marketing surveillance by the FDA todetermine our compliance with all regulatory requirements. Our failure to comply with applicable regulatory requirements could result in the FDA or a courtinstituting a wide variety of enforcement actions against us, including a public "Warning Letter"; an order to shut down some or all manufacturingoperations; a recall of products; fines or civil penalties; seizure or detention of our products; refusing our requests for 510(k) clearance or a PMA of new ormodified products; withdrawing 510(k) clearance or PMA approvals already granted to us; and criminal prosecution.Our manufacturing processes and those of some of our suppliers must comply with the FDA’s Quality System Regulation, or QSR, which governs themethods 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 QSR through unannounced inspections. If we, or one of our suppliers, fail a QSRinspection, or if a corrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action, and our operationscould 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, the FDA’s adverse event reporting requirements and the FDA’s reporting requirements for field correction or product removals. The FDA hasrecently placed increased emphasis on its scrutiny of compliance with the QSR and these other postmarket requirements.If we, or one of our suppliers, violate the FDA’s requirements or fail to take adequate corrective action in response to any significant compliance issueraised by the FDA, the FDA can take various enforcement actions which could cause our product sales and profitability to suffer.In addition, most other countries require us and our suppliers to comply with manufacturing and quality assurance standards for medical devices thatare similar to those in force in the United States before marketing and selling our products in those countries. If we, or our suppliers, should fail to do so, wewould lose our ability to market and sell our products in those countries.If we cannot obtain and maintain marketing clearance or approval from governmental agencies, we will not be able to sell our products.Our products are medical devices that are subject to extensive regulation in the United States and in the foreign countries in which they are sold. Unlessan exemption applies, each medical device that we wish to market in the United States must receive either 510(k) clearance or premarket approval (PMA)from the FDA before the product can be sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearance procedure, also known as “premarketnotification,” is the process we have used for our current products. This process usually takes from four to twelve months from the date the premarketnotification is submitted to the FDA, but may take significantly longer. Although we have obtained 510(k) clearances for our current products, our clearancesmay be revoked by the FDA if safety or effectiveness problems develop with the devices. The PMA process is much more costly, lengthy and uncertain. Itgenerally takes from one to three years from the date the application is submitted to, and filed with the FDA, and may take even longer. Regulatory regimes inother countries similarly require approval or clearance prior to our marketing or selling products in those countries. We rely on our distributors to obtainregulatory clearances or approvals of our products outside of the United States. If we are unable to obtain additional clearances or approvals needed to marketexisting or new products in the United States or elsewhere or obtain these clearances or approvals in a timely fashion or at all, or if our existing clearances arerevoked, our revenues and profitability may decline.Modifications to our current products may require new marketing clearances or approvals or require us to cease marketing or recall the modified productsuntil such clearances or approvals are obtained.Any modification to an FDA-cleared medical device that could significantly affect its safety or effectiveness, or that would constitute a major change ormodification in its intended use, requires a new FDA 510(k) clearance or, possibly, a premarket approval. The FDA requires every manufacturer to make itsown determination as to whether a modification requires a new 510(k) clearance or premarket approval, but the FDA may review and disagree with anydecision reached by the manufacturer. We have modified aspects of some of our devices since receiving regulatory clearance. We believed that some of thesemodifications did not require new 510(k) clearance or premarket approval and, therefore, we did not seek new 510(k) clearances or premarket approvals. Inthe future, we may make additional modifications to our products after they have received FDA clearance or approval and, in appropriate circumstances,determine that new clearance or approval is unnecessary. Regulations in other countries in which we market or sell, or propose to market or sell, our productsmay also28require that we make judgments about changes to our products and whether or not those changes are such that regulatory approval or clearance should beobtained. In the United States and elsewhere, regulatory authorities may disagree with our past or future decisions not to seek new clearance or approval andmay require us to obtain clearance or approval for modifications to our products. If that were to occur for a previously cleared or approved product, we may berequired to cease marketing or recall the modified device until we obtain the necessary clearance or approval. Under these circumstances, we may also besubject to significant regulatory fines or other penalties. If any of the foregoing were to occur, our financial condition and results of operations could benegatively impacted.Even after receiving regulatory clearance or approval, our products may be subject to product recalls, which may harm our reputation and divertmanagerial and financial resources.The FDA and similar governmental authorities in other countries have the authority to order mandatory recall of our products or order their removalfrom the market if there are material deficiencies or defects in design, manufacture, installation, servicing or labeling of the device, or if the governmentalentity finds that our products would cause serious adverse health consequences. A government mandated voluntary recall or field action by us could occur asa result of component failures, manufacturing errors or design defects, including labeling defects. Any recall of our products may harm our reputation withcustomers and divert managerial and financial resources.We may be subject to fines, penalties, injunctions or costly investigations if we are determined to be promoting the use of our products for unapproved or“off-label” uses.If we are incorrect in our belief that our promotional materials and training methods regarding physicians are conducted in compliance with regulationsof the FDA and other applicable regulations, and the FDA determines that our promotional materials or training constitutes promotion of an unapproved use,the FDA could request that we modify our training or promotional materials or subject us to regulatory enforcement actions, including the issuance of awarning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might takeaction if they consider promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penaltiesunder other statutory authorities, such as laws prohibiting false claims for reimbursement. Any of these results could have a material adverse effect on ourfinancial position or results of operations.In June 2014 we received a subpoena from the U.S. Department of Justice (the “DOJ”) requesting documents in relation to a criminal and civilinvestigation the DOJ is conducting regarding BTG International, Inc.’s LC Bead product beginning in 2003. RITA Medical Systems and AngioDynamics,Inc., after our acquisition of RITA, was the exclusive distributor of LC Beads in the United States from 2006 through December 31, 2011. We are cooperatingfully with this investigation and at this time are unable to predict its scope, duration or outcome. In April 2015 we received a subpoena from the DOJrequesting documents in relation to a criminal and civil investigation the DOJ is conducting regarding purported promotion of certain of our VenaCureEVLT products for un-cleared indications. As of May 31, 2017 the Company accrued $12.5 million for these matters and in August 2017, the Companyagreed in principle with the government to resolve these matters for approximately $12.5 million. If our employees or agents violate the U.S. Foreign Corrupt Practices Act or anti-bribery laws in other jurisdictions, we may incur fines or penalties, orexperience other adverse consequences.We are subject to the U.S. Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery laws in international jurisdictions, including the UK Anti-Bribery Act, which generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtainingor retaining business. Because of the predominance of government-sponsored healthcare systems around the world, many of our customer relationshipsoutside of the United States are with governmental entities and are therefore subject to such anti-bribery laws. Our sales to customers and distributors outsideof the United States have been increasing and we expect them to continue to increase in the future. If our employees or agents violate the provisions of theFCPA or other anti-bribery laws, we may incur fines or penalties, we may be unable to market our products in other countries or we may experience otheradverse consequences which could have a material adverse effect on our operating results or financial condition.Laws and regulations governing the export of our products could adversely impact our business.The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), and the Bureau of Industry and Security at the U.S. Department ofCommerce (BIS), administer certain laws and regulations that restrict U.S. persons and, in some instances, non-U.S. persons, in conducting activities,transacting business with or making investments in certain countries, governments, entities and individuals subject to U.S. economic sanctions. Due to ourinternational operations, we are subject to29such laws and regulations, which are complex, restrict our business dealings with certain countries and individuals, and are constantly changing. Furtherrestrictions may be enacted, amended, enforced or interpreted in a manner that materially impacts our operations.From time to time, certain of our subsidiaries have limited business dealings in countries subject to comprehensive sanctions, including Iran, Sudan,Syria, Cuba and those in the region of Crimea. Certain of our subsidiaries sell medical devices and surgical tools, and may provide related services, todistributors and other purchasing bodies in such countries. These business dealings represent an insignificant amount of our consolidated revenues andincome, but expose us to a heightened risk of violating applicable sanctions regulations. Violations of these regulations are punishable by civil penalties,including fines, denial of export privileges, injunctions, asset seizures, debarment from government contracts and revocations or restrictions of licenses, aswell as criminal fines and imprisonment. We have established policies and procedures designed to assist with our compliance with such laws and regulations.However, there can be no assurance that our policies and procedures will effectively prevent us from violating these regulations in every transaction in whichwe may engage, and such a violation could adversely affect our reputation, business, financial condition, results of operations and cash flows.Changes in reimbursement levels by governmental or other third-party payors for procedures using our products may cause our revenues to decline.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 medical devicecompanies because it affects which products customers purchase and the prices they are willing to pay. Reimbursement varies by country and cansignificantly impact the acceptance of new technology. Implementation of healthcare reforms in the United States and in other countries may limit, reduce oreliminate reimbursement for our products and adversely affect both our pricing flexibility and the demand for our products. Even when we develop apromising new product, we may find limited demand for the product unless reimbursement approval is obtained from private and governmental third partypayors.Third-party payors have adopted, and are continuing to adopt, a number of healthcare policies intended to curb rising healthcare costs. These policiesinclude:•controls on government-funded reimbursement for healthcare services and price controls on medical products and services providers;•challenges to the pricing of medical procedures or limits or prohibitions on reimbursement for specific devices and therapies through othermeans; and•the introduction of managed care systems in which healthcare providers contract to provide comprehensive healthcare for a fixed cost perperson.We are unable to predict whether federal, state or local healthcare reform legislation or regulation affecting our business may be proposed or enacted inthe future, or what effect any such legislation or regulation would have on our business. Changes in healthcare systems in the United States or elsewhere in amanner that significantly reduces reimbursement for procedures using our medical devices or denies coverage for these procedures, or adverse decisionsrelating to our products by administrators of these systems in coverage or reimbursement issues, would have an adverse impact on the acceptance of ourproducts and the prices which our customers are willing to pay for them.RISKS RELATED TO INTELLECTUAL PROPERTYIf we fail to adequately protect our intellectual property rights, we may not be able to generate revenues from new or existing products and our businessmay suffer.Our success depends in part on obtaining, maintaining and enforcing our patents, trademarks and other proprietary rights, and our ability to avoidinfringing the proprietary rights of others. We take precautionary steps to protect our technological advantages and intellectual property. We rely uponpatent, trade secret, copyright, know-how and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual propertyrights and protect our products. However, no assurances can be made that any pending or future patent applications will result in the issuance of patents, thatany current or future patents issued to, or licensed by, us will not be challenged or circumvented by our competitors, or that our patents will not be foundinvalid.30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 noassurance 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 providesignificant protection or commercial advantage, or whether any existing or future patent will be circumvented by a more basic patent, thus requiring us toobtain a license to produce and sell the product. Generally, patent applications can be maintained in secrecy for at least 18 months after their earliest prioritydate. In addition, publication of discoveries in the scientific or patent literature often lags behind actual discoveries. Therefore, we cannot be certain that wewere the first to invent the subject matter covered by each of our pending U.S. patent applications or that we were the first to file non-U.S. patent applicationsfor such subject matter.Additionally, we rely on trade secret protection for certain unpatented aspects of our proprietary technology. There can be no assurance that others willnot independently develop or otherwise acquire substantially equivalent proprietary information or techniques, that others will not gain access to ourproprietary technology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees andconsultants to execute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentialityagreements also require our employees to assign to us all rights to any inventions made or conceived during their employment with us. We also generallyrequire our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that theseagreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer or disclosure of confidential informationor inventions.If we are not able to adequately protect our intellectual property, our market share, financial condition and results of operations may suffer.If third parties claim that our products infringe their intellectual property rights, we may be forced to expend significant financial resources andmanagement time defending against such actions and our financial condition and our results of operations could suffer.Third parties may claim that our products infringe their patents and other intellectual property rights. Identifying third-party patent rights can beparticularly difficult because, in general, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date. Somecompanies in the medical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were tochallenge our patents, licenses or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we couldincur substantial litigation costs, be forced to make expensive changes to our product design, pay royalties or other fees to license rights in order to continuemanufacturing and selling our products, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consumeour financial resources but also divert our management’s time and effort. Such claims could also cause our customers or potential customers to purchasecompetitors’ products or defer or limit their purchase or use of our affected products until resolution of the claim.RISKS RELATED TO OUR STOCK PRICEOur future operating results are difficult to predict and may vary significantly from quarter to quarter, which may adversely affect the price of our commonstock.The ongoing introduction of new products and services that affect our overall product mix make the prediction of future operating results difficult. Youshould not rely on our past results as any indication of future operating results. The price of our common stock will likely fall in the event that our operatingresults do not meet the expectations of analysts and investors. Comparisons of our quarterly operating results are an unreliable indication of our futureperformance because they are likely to vary significantly based on many factors, including:•the level of sales of our products and services in our markets;•our ability to introduce new products or services and enhancements in a timely manner;•the demand for and acceptance of our products and services;•the success of our competition and the introduction of alternative products or services;•our ability to command favorable pricing for our products and services;•the growth of the market for our devices and services;•the expansion and rate of success of our direct sales force in the United States and internationally and our independent distributorsinternationally;•actions relating to ongoing FDA compliance;•the effect of intellectual property disputes;31•the size and timing of orders from independent distributors or customers;•the attraction and retention of key personnel, particularly in sales and marketing, regulatory, manufacturing and research and development;•unanticipated delays or an inability to control costs;•general economic conditions as well as those specific to our customers and markets; and•seasonal fluctuations in revenue due to the elective nature of some procedures.Our stock price may be volatile, which may cause the value of our stock to decline or subject us to a securities class action litigation.The trading price of our common stock price may be volatile and could be subject to wide fluctuations in price in response to various factors, many ofwhich are beyond our control, including:•general economic, industry and market conditions;•actions by institutional or other large stockholders;•the depth and liquidity of the market for our common stock;•volume and timing of orders for our products;•developments generally affecting medical device companies;•the announcement of new products or product enhancements by us or our competitors;•changes in earnings estimates or recommendations by securities analysts;•investor perceptions of us and our business, including changes in market valuations of medical device companies; and•our results of operations and financial performance.In addition, the stock market in general, and the NASDAQ Stock Market and the market for medical devices in particular, have experienced substantialprice and volume volatility that is often seemingly unrelated to the operating performance of particular companies. These broad market fluctuations maycause the trading price of our common stock to decline. In the past, securities class action litigation has often been brought against a company after a periodof volatility in the market price of its common stock. We may become involved in this type of litigation in the future. Any securities litigation claims broughtagainst us could result in substantial expense and the diversion of management’s attention from our business.We may not attain the guidance set forth in the three-year plan that was presented to our investors in April 2017 which could have an adverse impact onour stock price.In April 2017, guidance targets for revenue, adjusted earnings per share, adjusted EBITDAS, free cash flow, adjusted gross margin and leverage forthe next three years were presented to our investors. If we do not achieve this guidance this could have an adverse effect on our stock price as investors couldbegin to lose confidence in the performance of the Company and its ability to forecast and execute.Item 1B.Unresolved Staff Comments.None. 32Item 2.Properties.During the year ended May 31, 2017, we operated in the following locations:Location Purpose Approx.Sq.

Bard, Inc. v. AngioDynamics, Inc.On January 11, 2012, C.R. Bard, Inc. (“Bard”) filed a suit in the United States District Court of Utah claiming certain of our implantable port productsinfringe on three U.S. patents held by Bard (the "Utah Action"). Bard is seeking unspecified damages and other relief. The Court denied Bard’s motion for pre-trial consolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but had asked forsupplemental briefing on the issue of whether to conduct a common Markman hearing. Meanwhile, we filed petitions for reexamination in the US Patent andTrademark Office ("PTO") which seek to invalidate all three patents asserted by Bard in the litigation. Our petitions were granted and 40 of Bard's 41 patentclaims were rejected and, following further proceedings, the Patent Office issued a Final Rejection of all 40 claims subject to reexamination. Thereafter, Bardfiled appeals to the PTO Board of Appeals and Interferences for all three reexams. The parties completed briefing on the appeals and oral argument was heldon June 18, 2015. The Patent Office issued decisions in the three appeals. In one (issued on March 11, 2016 for US Patent No. 7,785,302), the rejections of sixof the ten claims under reexamination were affirmed, but were reversed on four of the ten claims. In the second (issued on March 24, 2016 for U.S. Patent No.7,959,615), the rejections of eight of the ten claims under reexamination were affirmed but the rejections of the other two of the ten claims were reversed. Inthe third (issued on March 29 for U.S. Patent No. 7,947.022) the rejections of all twenty claims under reexamination were affirmed. Bard then filed Requestsfor Rehearing in all three reexamination appeals and the Company filed Requests for Rehearing in two of the reexamination appeals (the ‘302 and ‘615patent reexaminations). Each party filed comments in Opposition to the other party’s Rehearing Requests,. The PTO has since issued decisions denying allRehearing Requests - - on February 1, 2017 for the ‘302; on February 17, 2017 for the ‘022; and on February 21, 2017 for the ‘615. In the ‘302 and ‘022, thePTO modified its characterization of one prior art reference. Bard has since filed a Notice of Appeal to the Federal Circuit Court of Appeals in all threereexams and we filed Cross-Appeals in the ‘302 and the ‘615 reexams. The parties are in the process of preparing and filing the various appellate briefs,starting with Bard’s Opening Brief which is currently due on July 31, 2017 and ending with our Reply Brief which is currently due on November 6, 2017. The Utah Action has been stayed pending final resolution of the PTO process. We believe these claims are without merit and intend to defend themvigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probablenor reasonably estimable.On March 10, 2015, C.R. Bard, Inc. and Bard Peripheral Vascular, Inc. (“Bard”) filed suit in the United States District Court for the District of Delawareclaiming certain of our implantable port products infringe on three U.S. patents held by Bard (the “Delaware Action). Bard is seeking unspecified damagesand other relief. The patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1, 2015, we filed two motions inresponse to Bard’s Complaint - one sought transfer to the District of Utah where the Utah Action is currently pending, and the other sought dismissal of theentire complaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statuteand in light of recent authority from the U. S. Supreme Court. On January 12, 2016, the court issued a decision denying both motions. We have since servedan Answer and Counterclaim to which Bard has served a Reply. On March 10, 2016, the Court held a case management conference, and, on March 14, 2016,the court entered a Scheduling Order which set, inter alia, a Markman hearing for March 10, 2017, a summary judgment hearing for December 8, 2017 andtrial for March 12, 2018. The parties have served various discovery requests on each other, and have been producing documents to each other; on May 27,2016 Bard served its Infringement Contentions which identified all the port products accused of infringement; and, on June 24, 2016, we served InvalidityContentions which detail various grounds for invalidating the three asserted patents. The parties completed briefing on the claim construction issues and theMarkman hearing was held on March 10, 2017. A decision is expected on or about May 12, 2017, and the Court issued its Claim Construction Order on May19, 2017. The Court has since amended the Scheduling Order to provide for the completion of Expert Discovery on October 30, 2017; briefing on Case-Dispositive Motions between November 17, 2017 and January 24, 2018 with oral argument set for February 22, 2018 and trial to commence May 29, 2018.We believe these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigationbecause it is not yet possible to determine if a potential loss is probable nor reasonably estimable.AngioDynamics, Inc. v. C.R. Bard, Inc.On May 30, 2017, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v.C.R. Bard, Inc. and Bard Access Systems, Inc. (“Bard”). In this action, we allege that Bard has illegally tied the sales of its tip location systems to the sales ofits PICCs. We allege that this practice violates the federal antitrust laws and has had, and continues to have, an anti-competitive effect in the market forPICCs. We seek both monetary damages and injunctive relief. The Court has set an initial case management conference for August 29, 2017.34Governmental InvestigationsIn June 2014 we received a subpoena from the U.S. Department of Justice (the “DOJ”) requesting documents in relation to a criminal and civilinvestigation the DOJ is conducting regarding BTG International, Inc.’s LC Bead® product beginning in 2003. RITA Medical Systems and AngioDynamics,Inc., after its acquisition of RITA, was the exclusive distributor of LC Beads in the United States from 2006 through December 31, 2011. We are cooperatingfully with this investigation.In April 2015 we received a subpoena from the DOJ requesting documents in relation to a criminal and civil investigation the DOJ is conductingregarding purported promotion of certain of AngioDynamics’ VenaCure EVLT products for un-cleared indications. We are cooperating fully with thisinvestigation.As of May 31, 2017 the Company accrued $12.5 million for these matters and in August 2017, the Company agreed in principle with the government toresolve these matters for approximately $12.5 million.

Our devices are generally used in minimally invasive, image-guided procedures. Most of our products are intended to be used once and then discarded, or they may be temporarily implanted for short- or longer-term use.Our business operations cross a variety of markets. Our financial performance is impacted by changing market dynamics, which have included anemergence of value-based purchasing by healthcare providers, consolidation of healthcare providers,38the increased role of the consumer in health care decision-making and an aging population, among others. In addition, our growth is impacted by changeswithin our sector, such as the merging of competitors to gain scale and influence; changes in the regulatory environment for medical device; and fluctuationsin the global economy.Our sales and profitability growth also depends, in part, on the introduction of new and innovative products, together with ongoing enhancements to ourexisting products. Expansions to our product offerings are created through internal product development, technology licensing and strategic alliances. Werecognize the importance of, and intend to continue to make investments in, research and development activities and business development opportunitiesand feel confident that our existing capital structure and free cash flow generation will allow us to properly fund those activities.We sell our products in the United States through a direct sales force, and outside the U.S. through a combination of a direct sales and distributorrelationships. We expect our businesses to grow in both sales and profitability through geographic expansion, market penetration, new product introductionsand increasing our direct presence internationally.Strategic Initiatives to Drive GrowthThroughout the year, we introduced strategic moves designed to streamline our business, improve our overall business operations and position ourselvesfor growth. Those initiatives included:•Introduction of new corporate strategy. As outlined in an Investor Day held in New York City in the fourth quarter, leadership introduced a strategicapproach that would include portfolio management with product categories designated into “invest” and “maintain” businesses; continued efforts toimprove operational performance; international expansion; and an ability to pursue growth through organic and inorganic opportunities throughstrong cash generation. In addition to introducing the strategy, the company also put forth projected financial metrics anticipated for the 2018, 2019and 2020 fiscal years.•Operational Consolidation. The Company announced a planned consolidation of operations from the Manchester, GA and Denmead, UK facilitiesinto the Glens Falls and Queensbury, NY manufacturing facilities in the third quarter. The consolidation will result in streamlined operations,reduced costs, optimized inventory management and gross margin improvement. As part of the plan, the Company expects to incur restructuringexpenses, including severance and retention, equipment transfer, set-up and purchases, regulatory expenses, lease termination expenses and othermiscellaneous expenses. The plan is expected to be completed in the third quarter of fiscal year 2018.•Implementation of a new product development process. The company introduced a robust product development process intended to improve theCompany’s ability to bring new products to market.•Rationalization of underperforming or below-cost products. This initiative eliminated more than 900 SKUs and was partnered with a price increaseon products that did not have a profitable cost structure.•New members of the executive leadership team. Following his arrival in April 2016, President and Chief Executive Officer James C. Clemmerwelcomed several members to the AngioDynamics leadership team, including Executive Vice President and Chief Financial Officer Michael C.Greiner, Senior Vice President of Quality and Regulatory Affairs Warren G. Nighan, Senior Vice President and General Manager of the VascularAccess Global Business Unit Chad T. Campbell, Senior Vice President and General Manager of the Peripheral Vascular Global Business Unit RobertA. Simpson and Senior Vice President of Human Resources Heather J. Daniels Cariveau.Recent DevelopmentsIn addition to the deliberate actions taken by management as listed above, several significant developments occurred over the course of the fiscal yearwhich impacted our business, including:The Company added two members to the Board of Directors, Eileen Auen and Jan Reed. Auen most recently served as Executive Chairman of Helios, a$1 billion healthcare services firm. Reed most recently was Senior Vice President, General Counsel and Corporate Secretary at Walgreens Boots Alliance.The Company made the decision to discontinue its investment in the TiLo product that was acquired in August 2013 as part of the Clinical Devicesacquisition. This decision resulted in the write-off of the acquired in-process research and development (IPR&D) of $3.6 million along with a $3.1 milliongain from the reduction in the fair value of contingent consideration liability associated with future milestones that will no longer be met.39The Company revised the sales projections for the AngioVac product as a result of reviews performed by executive management across all products. Theadjustments to the sales projections resulted in a $13.4 million gain from the reduction in the fair value of the contingent liability that is based on lowerprojected sales volume over the contractual earn out period.The Company decided to terminate its agreements with EmboMedics. The termination of these agreements resulted in a write-off of the initial $2.0million investment in EmboMedics (Note 2).The Board of Directors approved a share repurchase program (the “Repurchase Program”) under which they authorized the Company the option torepurchase up to $25.0 million of its outstanding common stock during the twenty-four month period ending November 6, 2018. During the second andfourth quarter of fiscal year 2017, the Company repurchased a total of 870,000 shares of common stock in the open market at an aggregate cost of $13.6million under the Repurchase Program.The Company entered into a new credit agreement ("Credit Agreement") which provides for a $100.0 million senior secured term loan facility ("TermLoan") and a $150.0 million senior secured revolving credit facility ("Revolving Facility", and together with the Term Loan, "The Facilities") along with upto a $20.0 million sublimit for letters of credit and a $5.0 million limit for swing line loans. With the proceeds from the Credit Agreement, the existing creditfacility that was entered into in September 2013 was paid down in full.The Company announced to employees an Operational Consolidation strategy which included the consolidation of the Manchester, GA and Denmead,UK facilities into the Glens Falls and Queensbury, NY manufacturing facilities. As part of the plan, the Company expects to incur restructuring expenses,including severance and retention, equipment transfer, set-up and purchases, regulatory expenses, lease termination expenses and other miscellaneousexpenses. The plan is expected to be completed in the third quarter of fiscal year 2018.Following completion of the sale of common stock pursuant to the Underwriting Agreement, Avista Capital Partners’ beneficial ownership inAngioDynamics has been reduced to zero as they sold their entire position in AngioDynamics. As a result, in accordance with the terms of his appointment toAngioDynamics’ Board of Directors and the terms of the Stockholders Agreement, David Burgstahler resigned as a director on April 12, 2017.The Company filed a lawsuit alleging that C.R. Bard has violated federal antitrust laws by illegally tying the sale of its tip location systems to its line ofperipherally inserted central catheters. The Company claims that these actions by Bard are preventing competition in the marketplace and limiting patientaccess to superior technology.The Company issued a voluntary recall of its Acculis probes that were sold over the past two years. As a result of this voluntary recall, the companydecided to also do a voluntary market withdrawal of its Acculis capital systems and discontinue selling the product. The voluntary recall resulted in a deferralof revenue of $2.6 million and an increase of $2.6 million in inventory and hardware asset reserves. The total impact to income before taxes of the recall was$4.5 million. Additional costs will be incurred in fiscal year 2018 related to the market withdrawal of the Acculis capital systems.The Company received notification in the fourth quarter of 2017 that a $1.8 million refund from the Internal Revenue Service related to prior medicaldevice taxes paid would be received.As of May 31, 2017 the Company accrued $12.5 million for these matters and in August 2017, the Company agreed in principle with the government toresolve these matters for approximately $12.5 million.Management's Use of Non-GAAP MeasuresNet sales “on a constant currency basis” is a non-GAAP measure. The Company analyzes net sales on a constant currency basis to better measure thecomparability of results between periods. Because changes in foreign currency exchange rates have a non-operating impact on net sales, the Companybelieves that evaluating growth in net sales on a constant currency basis provides an additional and meaningful assessment of net sales to both managementand the company’s investors. Constant currency growth rates are calculated by subtracting the current period's local currency sales at the prior period’sexchange rate from the current period’s local currency sales at the current period’s exchange rate.Constant currency growth rates are not indicative of changes in corresponding cash flows. The limitation of these non-GAAP measures is that they donot reflect results on a standardized reporting basis. Non-GAAP measures are intended to supplement the applicable GAAP disclosures and should not beviewed as replacements of GAAP results.40Critical Accounting Policies and Use of EstimatesOur significant accounting policies are summarized in Note 1 to Notes to Consolidated Financial Statements included elsewhere in this Annual Reporton Form 10-K. While all these significant accounting policies affect the reporting of our financial condition and results of operations, we view certain ofthese policies as critical. Policies determined to be critical are those policies that have the most significant impact on our financial statements and require usto use a greater degree of judgment and/or estimates. Actual results may differ from those estimates. The accounting policies identified as critical are asfollows:Revenue RecognitionWe recognize revenue in accordance with generally accepted accounting principles as outlined in the SEC’s authoritative guidance on revenuerecognition which requires that four criteria be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) the price is fixedor determinable; (iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. Decisions relative tocriterion (iii) regarding collectability are based upon our judgments, as discussed under “Accounts Receivable” in Note 1, and should conditions change inthe future and cause us to determine this criterion is not met; our results of operations may be affected. We recognize revenue, net of sales taxes assessed byany governmental authority, as products are shipped, based on F.O.B. shipping point terms when title and risk of loss passes to customers. We negotiateshipping and credit terms on a customer-by-customer basis and products are shipped at an agreed upon price. All product returns must be pre-approved by usand customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least 12 monthsremaining prior to its expiration date. Charges for discounts, returns, rebates and other allowances are recognized as a deduction from revenue on an accrualbasis in the period in which the revenue is recorded. The accrual for product returns, discounts and other allowances is based on the Company’s history.Income TaxesWe calculate income tax expense for each jurisdiction in which we operate. This involves estimating actual current taxes due plus assessing temporarydifferences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. We periodically evaluatedeferred tax assets, capital loss carryforwards and tax credit carryforwards to determine their recoverability based primarily on our ability to generate futuretaxable income and capital gains. Where it is more-likely-than-not these will not be recovered, we estimate a valuation allowance and record a correspondingadditional tax expense in our statement of operations.We file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject toexamination by taxing authorities throughout the world. Fiscal years 2014 through 2017 remain open to examination by the various tax authorities. Weanalyzed filing positions in all of the Federal and state jurisdictions where we are required to file income taxes, as well as all open tax years in thesejurisdictions and believe that our income tax filing positions and deductions will be sustained on audit and we do not anticipate any adjustments will resultin a material adverse effect on our financial condition, results of operations or cash flows.Acquisitions and Contingent ConsiderationIn a business combination, the acquisition method of accounting requires that the identifiable assets acquired and liabilities assumed be measured attheir fair value, with goodwill being the excess value of consideration paid over the fair value of the net identifiable assets acquired. IP R&D is capitalizedand recorded as an indefinite-lived intangible asset at the acquisition date, contingent consideration is recorded at fair value at the acquisition date, andtransaction costs are expensed as incurred. When the Company acquires net assets that are not accounted for as a business combination, no goodwill isrecognized.The fair value of the liability for contingent consideration recorded on the acquisition date is based on probability weighted estimated cash flowstreams, discounted back to present value using a discount rate determined in accordance with accepted valuation methods. The liability for contingentconsideration is remeasured to fair value at each reporting period with changes recorded in earnings until the contingency is resolved.Goodwill and Intangible AssetsIntangible assets other than goodwill, indefinite lived intangible assets and in process research and development ("IP R&D") are amortized over theirestimated useful lives, which range between two to eighteen years, on either a straight-line41basis over the expected period of benefit or as revenues are earned from the sales of the related products. We periodically review the estimated useful lives ofour intangible assets and review such assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets maynot be recoverable. If an intangible asset is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fairvalue of the asset.Acquired IP R&D is not amortized until completion and development of the project, at which time the IP R&D becomes an amortizable asset with anappropriate useful life and an amortization method is determined. If the related project is not completed in a timely manner or the project is terminated orabandoned, we may have an impairment related to the IP R&D, calculated as the excess of the asset’s carrying value over its fair value.Our policy defines IP R&D as the value assigned to those projects for which the related products have not received regulatory approval and have noalternative future use. Determining the portion of the purchase price allocated to IP R&D requires us to make significant estimates. The amount of thepurchase price allocated to IP R&D is determined by estimating the future cash flows of each project or technology and discounting the net cash flows backto their present values. The discount rate used is determined at the time of measurement in accordance with accepted valuation methods. Thesemethodologies include consideration of the risk of the project not achieving commercial feasibility.Goodwill and other intangible assets that have indefinite useful lives are not amortized, but rather, are tested for impairment annually or morefrequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiableintangible assets acquired in each business combination. Goodwill and intangible assets have been recorded at either incurred or allocated cost. Allocatedcosts were based on respective fair market values at the date of acquisition.For goodwill, the impairment test requires a comparison of the estimated fair value of the reporting unit to which the goodwill is assigned to the sum ofthe carrying value of the assets and liabilities of that unit. The determination of reporting units also requires management judgment. We consider whether areporting unit exists within a reportable segment based on the availability of discrete financial information that is regularly reviewed by segmentmanagement. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of the reporting unit, the carrying value ofthe reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in an impairment charge. TheCompany utilizes either discounted cash flow models or other valuation models, such as comparative transactions and market multiples, to determine the fairvalue of our reporting unit. We must make assumptions about future cash flows, future operating plans, discount rates, comparable companies, marketmultiples, purchase price premiums and other factors in those models. Different assumptions and judgment determinations could yield different conclusionsthat would result in an impairment charge to income in the period that such change or determination was made.ContingenciesWe are involved, both as a plaintiff and a defendant, in various legal proceedings that arise in the ordinary course of business, including patentinfringement and product liability, as further discussed in Note 15 to our consolidated financial statements. Accruals recorded for various contingenciesincluding legal proceedings, self insurance and other claims, are based on judgment, the probability of losses and, where applicable, the consideration ofopinions of internal and/or external legal counsel, internal and/or external technical consultants and actuarially determined estimates. When a range isestablished but a best estimate cannot be made, we record the minimum loss contingency amount, which could be zero. An estimate is often initiallydeveloped substantially earlier than the ultimate loss is known and is reevaluated each accounting period. As information becomes known, additional lossprovision is recorded when either a best estimate can be made or the minimum loss amount is increased. When events result in an expectation of a morefavorable outcome than previously expected, our best estimate is changed to a lower amount. We record receivables from third-party insurers up to theamount of the related liability when we have determined that existing insurance policies will provide reimbursement. In making this determination, weconsider applicable deductibles, policy limits and the historical payment experience of the insurance carriers. Receivables are not netted against the relatedliabilities for financial statement presentation.Results of Operations for the years ended May 31, 2017 and 2016For the fiscal year ended May 31, 2017, we reported net income of $5.0 million, or $0.14 income per diluted share, on net sales of $349.6 millioncompared to a fiscal 2016 net loss of $43.6 million, or $1.21 loss per diluted share, on net sales of $353.9 million.42Net SalesNet sales - Net sales are derived from the sale of our products and related freight charges, less discounts and returns.Net sales for the year ended May 31, 2017 and 2016 were: For the year ended May 31,(in thousands)2017 2016 % Growth CurrencyImpact (Pos)Neg ConstantCurrencyGrowth Non-GAAPNet Sales by Product Category Peripheral Vascular$208,602 $205,620 1% Vascular Access96,481 99,375 (3)% Oncology/Surgery44,560 48,895 (9)% Total349,643 353,890 (1)% 0% (1)% Net Sales by Geography United States$282,168 $285,824 (1)% 0% (1)% International67,475 68,066 (1)% 2% 1%Total$349,643 $353,890 (1)% 0% (1)%For year ended May 31, 2017, net sales decreased $4.2 million to $349.6 million compared to the year ended May 31, 2016.•Consolidated and U.S. net sales decreased from the prior year as a result of decreased net sales from Vascular Access and Oncology Surgery. Thisdecrease was partially offset by 1% year over year growth in our Peripheral Vascular franchise.Peripheral Vascular•Total Peripheral Vascular sales increased $3.0 million primarily attributable to increased sales volume of Angiographic and Core products of $9.9million. This increased sales volume was partially offset by a decrease of volume in Fluid Management, Venous and AngioVac of $5.6 million. Thedecrease in Fluid Management was attributed to a discontinuance of our inflation device and automation challenges in the European markets.Although AngioVac procedures were up year over year, AngioVac unit sales decreased by $1.4 million due to available inventory already in themarket place.•US Peripheral Vascular sales increased $2.8 million and international Peripheral Vascular sales increased $0.2 million which was primarily due toincreased sales volume of Angiographic catheters. This increased sales volume was offset by a decrease in volume in Fluid Management, Venousand AngioVac.Vascular Access•Total Vascular Access sales decreased $2.9 million primarily in our non-BioFlo businesses. Our BioFlo product line grew by $4.8 million primarilydriven by growth in Midlines.•US Vascular Access sales declined by 5% due to softness across the portfolio offset by Midline and BioFlo dialysis which continued to gain tractionin the marketplace.•International Vascular Access sales increased 15% due to the market penetration of BioFlo PICCs.Oncology/Surgery•Total Oncology/Surgery sales decreased $4.3 million year over year primarily due to fewer sales of capital units in Microwave and NanoKnife aswell as the $2.6 million deferral of revenue related to the Acculis probe recall that was announced in the fourth quarter of fiscal year 2017.43•U.S. Oncology/Surgery declined by 8%, driven primarily through lower capital and disposable sales in Radio Frequency and Microwave offset byNanoKnife growth. The decrease is also attributed to a $1.4 million deferral of revenue related to the Acculis probe recall that was announced in thefourth quarter of fiscal year 2017.•International Oncology/Surgery sales decreased 10% year over year as a result of lower NanoKnife capital and disposable sales and a $1.2 milliondeferral of revenue related to the Acculis probe recall that was announced in the fourth quarter of fiscal year 2017.Gross Profit, Operating expenses, and Other income (expense) For the year ended May 31,(in thousands) 2017 2016 % ChangeGross profit (exclusive of intangible amortization) $176.2 $174.3 1.1 %Gross profit % of sales 50.4% 49.3% Research and development $25.3 $25.1 0.8 %% of sales 7.2% 7.1% Selling and marketing $78.8 $83.7 (5.9)%% of sales 22.5% 23.7% General and administrative $31.4 $30.6 2.6 %% of sales 9.0% 8.6% Gross profit - Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties and soldby us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead.Gross profit increased by $1.9 million compared to the prior year. The increase is attributable to the following: •In fiscal year 2017, a net charge of $4.5 million was recorded as a result of the Acculis probe recall.•In fiscal year 2016, a $5.9 million charge related to the write-off of Celerity inventory on hand and hardware assets after the business decision to nolonger pursue the Celerity Navigation project.•The remaining increase is driven by net productivity offset by price and mix of products.•The increase in gross profit as a percentage of 1.1% is attributed to the factors noted above.Research and development expenses - Research and development (“R&D”) expenses include internal and external costs to develop new products, enhanceexisting products, validate new and enhanced products, manage clinical, regulatory and medical affairs.R&D expense increased $0.2 million compared to the prior year. The increase is attributable to the following:•Increased headcount in the R&D department compared to the prior year resulted in $1.2 million in additional expense as well as expenses associatedwith consultants of $0.6 million and severance of $0.4 million.•These increases were partially offset by less project spend of $1.2 million, $0.6 million in samples and $0.2 million in travel and other expenses.•R&D expense as a percentage of sales remained consistent year over year.Sales and marketing expenses - Sales and marketing (“S&M”) expenses consist primarily of salaries, commissions, travel and related business expenses,attendance at medical society meetings, product promotions and marketing activities.S&M expense decreased by $4.9 million compared to the prior year. The decrease is attributable to the following:•There was a decrease in headcount from the prior year which resulted in a $2.5 million decrease in salaries and benefits.•The decrease in headcount along with a focus on reduced travel spend resulted in a decrease in travel expenses of $1.3 million.•There was a $0.7 million decrease in trade shows and meeting expenses along with a $0.7 million decrease in samples as a result of a focus onreducing expenses.•These decreases were partially offset by severance of $0.8 million.44•As a result of these decreases in S&M expenses, the percentage of S&M to sales decreased 1.2%.General and administrative expenses - General and administrative (“G&A”) expenses include executive management, finance, information technology,human resources, business development, legal, and the administrative and professional costs associated with those activities.G&A expense increased by $0.8 million compared to the prior year. The increase is attributable to the following:•Increased stock based compensation expense related to the new grant for the CEO along with two new board members of $1.7 million. Along withthe stock based compensation increase, bonus for fiscal year 2017 was accrued at a higher rate than the prior year which resulted in a $1.0 millionincrease to G&A expense.•Along with the appointment of new members in the executive leadership team, recruiting and relocation expenses resulted in an increase of $0.5million from the prior year•There was also an increase in professional fees of $0.3 million related to audit fees and director fees partially offset by a decrease in legal fees.•These increases were partially offset by decreases in compensation benefits of $0.5 million as a result of a reduction in benefit claims, depreciationexpense of $0.8 million, $0.2 million in facilities expenses including insurance, lease expenses and utilities, bad debt favorability of $0.4 millionand other miscellaneous decreases in expenses of $0.4 million.

This waspartially offset by normal amortization of the present value discount on the contingent liabilities.Acquisition, restructuring and other items, net - Acquisition, restructuring and other items, net represents costs associated with mergers and acquisitions,restructuring expenses, legal costs that are related to litigation that is not in the ordinary course of business, legal settlements and other one-time items.Acquisition, restructuring and other items, net increased by $14.9 million compared to the prior year. The increase is attributable to the following:•In Q2 fiscal year 2017, the intangible assets associated with TiLo were written off for $3.6 million as a result of the decision to discontinue ourinvestment in the TiLo product along with a $2.0 million write-off of the investment in Embomedics due to termination of the agreement. The prioryear had asset impairments of $0.4 million.•There was $1.3 million of expense related to the plant consolidation which consisted mainly of severance and start-up costs to move the productlines including equipment transfer expenses, accelerated depreciation for assets that will not be transferred, validation and other start up costs. Theprior year had accelerated depreciation related to the Operational Excellence program of $1.0 million along with $0.5 million in other expenses.45•A litigation settlement accrual for $12.5 million was recorded in the fourth quarter of fiscal year 2017.•Legal expenses of $7.0 million which was a decrease of $0.5 million from the prior year.•Other miscellaneous items decreased $2.2 million from the prior year primarily attributable to a decrease in M&A expenses of $2.5 million offset bya gain in the prior year of $0.7 million related to the modification of stock based compensation awards for the former CEO.Medical device excise tax - Medical device excise tax is assessed on our U.S. product sales subject to exclusions and adjustments.•The Medical Device Excise Tax was suspended on January 1, 2016 therefore, fiscal year 2016 had seven months of the tax. In the current year, thereis a $1.8 million refund from the Internal Revenue Service related to prior medical device taxes paid.Other expenses - Other expenses include interest expense, foreign currency impacts, bank fees, and amortization of deferred financing costs.•The decrease in other expenses of $1.2 million was due to lower interest expense on lower outstanding debt and lower interest rates under the CreditAgreement along with unrealized foreign currency gains from re-measurement offset by the write off of the deferred financing fees from the originalcredit facility. Income Tax Provision (Benefit) For year ended May 31,(in thousands) 2017 2016Income tax expense (benefit) $4.8 $40.3Effective tax rate including discrete items 49% (1,240)%Our effective tax rate was 49% for fiscal 2017 compared with (1,240)% for the prior year. The current year rate reflects expense of $4.8 million primarilydriven by the impact of the US valuation allowance and the deferred tax liability related to intangibles that have an indefinite reversal period and cannot beused to support the deferred tax assets. The prior year rate primarily reflects income tax expense of $40.4 million related to full valuation allowance on ourUS net deferred tax assets that was established during fiscal 2016 and the deferred tax liability related to intangibles that have an indefinite reversal periodand cannot be used to support the deferred tax assets.At May 31, 2017, we had a net deferred tax liability of $26.1 million, after a valuation allowance on our US deferred tax assets of $48.3 million. Theincrease in the valuation allowance during fiscal 2017 was $6.1 million.A valuation allowance is provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assetswill not be realized. After careful consideration and weighing of all the available positive and negative evidence, the weight given to the threeyear cumulative loss and lack of a recent history of core earnings was difficult to overcome and a full valuation allowance related to the U.S. deferred taxassets was established in the period ending May 31, 2016. Management considered all available positive and negative evidence at May 31, 2017, andconsidering the cumulative loss in the U.S. over the three year period, determined that the valuation allowance is still required. Management will continue toreevaluate the positive and negative evidence at each reporting period and if future results as projected in the U.S. and the Company's tax planning strategiesare favorable, the valuation allowance may be removed, which could have a favorable material impact on the Company's results of operations in the period inwhich it is recorded.Results of Operations for the years ended May 31, 2016 and 2015For the fiscal year ended May 31, 2016, we reported net loss of $43.6 million, or $1.21 loss per basic and diluted common share, on net sales of $353.9million compared to a fiscal 2015 net loss of $3.4 million, or $0.09 per basic and diluted common share, on net sales of $356.5 million.Net SalesNet sales - Net sales are derived from the sale of our products and related freight charges, less discounts and returns.Net sales for the year ended May 31, 2016 and 2015 were:46 For the year ended May 31,(in thousands)2016 2015 % Growth CurrencyImpact (Pos)Neg ConstantCurrencyGrowth Non-GAAPNet Sales by Product Category Peripheral Vascular$205,620 $196,890 4% Vascular Access99,375 107,754 (8)% Oncology/Surgery48,895 51,890 (6)% Total353,890 356,534 (1)% 3% 2% Net Sales by Geography United States$285,824 $284,122 1% —% 1% International68,066 72,412 (6)% 4% (2)%Total$353,890 $356,534 (1)% 1% —%For year ended May 31, 2016, net sales decreased $2.6 million to $353.9 million compared to the year ended May 31, 2015. As shown in the tableabove, while consolidated net sales decreased by 1% excluding the negative impact from fluctuations in currency exchange rates, our sales were flat yearover year. The decline in net sales from vascular access and oncology surgery was partially offset by 4% year over year growth in our peripheral vascularfranchise. Our international sales were significantly impacted by unfavorable movement in currency exchange rates, particularly the Euro, British pound andCanadian dollarPeripheral Vascular sales increased $8.7 million primarily attributable to increased sales of AngioVac, Core and Venus products. While VascularAccess sales decreased $8.4 million primarily in our non-BioFlo businesses, our BioFlo line of products continued to gain traction in the marketplace.Oncology/Surgery sales decreased $3.0 million primarily due to fewer capital sales across all product lines compared to prior year. This was partially offset byincreases in the sales of disposables in our Microwave and NanoKnife product lines.U.S. sales increased $1.7 million due to growth in the Peripheral Vascular products, offset by a reduction in Vascular Access and Oncology/Surgerysales. While total US Vascular Access sales declined by $6.2 million overall, we saw growth in our U.S. BioFlo product lines of 18% year over year. U.S.Oncology/Surgery declined by $1.6 million, driven primarily through lower capital sales offset by growth in disposables. International sales decreased 2% ona constant-currency basis, due to a decline in Thermal Ablation and in the Vascular Access product lines.Gross Profit, Operating expenses, and Other income (expense) For the year ended May 31,(in thousands) 2016 2015 % ChangeGross profit $174.3 $175.8 (0.9)%Gross profit % of sales 49.3% 49.3% Research and development $25.1 $26.6 (5.6)%% of sales 7.1% 7.5% Selling and marketing $83.7 $82.4 1.6 %% of sales 23.7% 23.1% General and administrative $30.6 $30.0 2.0 %% of sales 8.6% 8.4% Gross profit - Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third partiesand sold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead.The $1.5 million decrease compared to 2015 is primarily attributable to a $5.9 million charge related to the write-off of Celerity inventory on hand andhardware assets after the business decision to no longer pursue the Celerity Navigation project. The prior year gross profit included a $4.8 million chargerelated to the voluntary Morpheus recall.47Research and development expenses - Research and development (“R&D”) expenses include internal and external costs to develop new products,enhance existing products, validate new and enhanced products, manage clinical, regulatory and medical affairs. The decrease in R&D costs for the yearended May 31, 2016 is due to reductions in project spend and restructuring. As a percentage of net sales, R&D expenses were 7.1% for fiscal 2016, comparedto 7.5% for fiscal 2015.Sales and marketing expenses - Sales and marketing (“S&M”) expenses consist primarily of salaries, commissions, travel and related business expenses,attendance at medical society meetings, product promotions and marketing activities. Increases in S&M expense for the year ended May 31, 2016 is theresult of investments made in the US sales force focused around retention and improved sales performance along with an increase in credit card fees. As apercentage of net sales, S&M expenses were 23.7% for fiscal 2016 compared to 23.1% for fiscal 2015.General and administrative expenses - General and administrative (“G&A”) expenses include executive management, finance, information technology,human resources, business development, legal, and the administrative and professional costs associated with those activities. Increases in G&A expenses forthe year ended May 31, 2016 are primarily the result of increased legal and audit fees.

The decrease from theprior year is due to a $10.5 million gain recognized as a result of reducing the estimated present value of future payments due on earn-outs in the prior yearcompared to $1 million in gains in 2016. These gains were partially offset in each period by amortization of the present value discount on the contingentliabilities.Acquisition, restructuring and other items, net - Expense for fiscal 2016 consists of $7.5 million of litigation expense, $2.5 million of M&A relatedexpenses, $1.9 million of severance, $0.7 million of a gain related to the modification of stock based compensation awards for the former CEO and $1.0million of accelerated depreciation associated with our operational excellence program, and other miscellaneous items. Expense for fiscal 2015 consists of$9.1 million of fixed and long-term asset impairments, $6.4 million of impairment on the NAMIC trademark, other costs associated with litigation, the recallof Morpheus, our operational excellence program, and other miscellaneous items. The impairment charges were primarily driven by a change in strategywithin our fluid management product development pipeline, as we moved away from our planned design of an Automated Power Injector.Medical device excise tax - Medical device excise tax is assessed on our U.S. product sales subject to exclusions and adjustments. The decrease ascompared to the prior year is attributable to the suspension of the medical device excise tax as of January 1, 2016.Other expenses - Other expenses include interest expense, foreign currency impacts, bank fees, and amortization of deferred financing costs. Theincrease in other expenses was primarily related to foreign currency losses.48Income Tax Provision (Benefit) For year ended May 31,(in thousands) 2016 2015Income tax expense (benefit) $40.3 $(4.7)Effective tax rate including discrete items (1,240)% 58%Our effective tax rate was (1,240)% for fiscal 2016 compared with 58% for the prior year. The current year rate reflects expense of $40.4 million relatedto a full valuation allowance on our US net deferred tax assets. The prior year rate reflects the benefit of $9.2 million nontaxable adjustment to the contingentliabilities related to Vortex Medical and Clinical Devices, and a seven month benefit from the R&D tax credit that expired on December 31, 2014, offset bynon-deductible interest expense related to contingent payments, true-ups of our fiscal year 2014 US income tax returns and the impact of the elimination ofthe ASC 718 APIC pool.At May 31, 2016, we had a net deferred tax liability of $21.7 million, after recording a valuation allowance of $42.2 million. The increase in thevaluation allowance was $40.4 million.While the net deferred tax asset at May 31, 2016 before the valuation allowance was $19.9 million, the Company was required to record a valuationallowance of $40.4 million due to deferred tax liabilities related to intangibles of $20.5 million that have an indefinite reversal period and can not be used tosupport the deferred tax asset.Liquidity and Capital ResourcesOur cash and cash equivalents totaled $47.5 million as of May 31, 2017, compared with $32.3 million as of May 31, 2016. Marketable securitiestotaled $1.2 million and $1.7 million as of May 31, 2017 and 2016, respectively, and consist of auction rate securities. As of May 31, 2017, total debtoutstanding was $97.5 million comprised of a term loan. The net debt to Consolidated EBITDA, as defined by the Credit Agreement (Note 11), is 1.4x. Thefair value of contingent consideration liability as of May 31, 2017 was $12.8 million.The table below summarizes our cash flows for the years ended May 31, 2017, 2016 and 2015: For the year ended May 31,(in thousands)2017 2016 2015Cash provided by (used in): Operating activities$55,745 $45,216 $25,685Investing activities(2,551) (7,569) (12,736)Financing activities(37,983) (23,663) (10,465)Effect of exchange rate changes on cash and cash equivalents— (42) (198)Net change in cash and cash equivalents$15,211 $13,942 $2,286During the twelve months ended May 31, 2017 and 2016, cash flows consisted of the following:Cash provided by operating activities•Net income was driven by higher gross margins, lower sales and marketing expenses as well as the medical device tax refund. Also impactingnet income, were non-cash items which consisted of $15.3 million of contingent consideration gains, $2.0 million in the write-off of theEmbomedics investment and $3.6 million in intangible write-offs related to TiLo. In addition, the prior year net income included a fullvaluation allowance on the Company's net operating losses.•With regards to working capital, the Company focused on optimizing both DSO and DPO which contributed to $15.2 million of workingcapital improvement. With respect to inventory, the $2.4 million reserve for Acculis inventory partially offset the inventory build related tothe plant consolidation.49Cash used in investing activities•$3.0 million in fixed asset additions compared to fixed asset additions of $2.3 million in the prior year.•$0.5 million in proceeds from an auction rate security that was called during fiscal year 2017.•The prior year also had $2.0 million in warrant additions related to EmboMedics and $3.3 million in intangible asset additions related to theMerz Distribution Agreement.Cash used in financing activities•Net $23.9 million in repayments on long-term debt after the proceeds from the Credit Agreement and repayment of the old credit agreementcompared to $16.3 million in repayments in the prior year. The increase from the prior year is due to the fact that the revolver was paid down infull as of the third quarter of fiscal year 2017.•$1.3 million in deferred financing fees related to the new credit agreement.•$10.7 million of proceeds from stock option and ESPP activity compared to $2.4 million in the prior year. The large increase is related to theexercise of stock based awards from executive management turnover that took place over the past year.•$9.9 million payment on earn-out liabilities which is consistent with the prior year.•$13.6 million from the repurchase of common shares in fiscal 2017. On November 7, 2016, the Company entered into a Credit Agreement that provides for a $100.0 million senior secured term loan facility and a $150.0million senior secured revolving credit facility, which includes up to a $20.0 million sublimit for letters of credit and a $5.0 million sublimit for swinglineloans.We believe that our current cash and investment balances, together with cash generated from operations and access to our revolving credit facility, willprovide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. If we seek to make significant acquisitions of otherbusinesses or technologies in the future for cash, we may require external financing.Our contractual obligations as of May 31, 2017 are set forth in the table below (in thousands).

Approximately 7.2% of our sales infiscal 2017 were denominated in foreign currencies. We do not have expenses denominated in foreign currencies at the level of our sales and as a result, ourprofitability is exposed to currency fluctuations. When the U.S. Dollar strengthens, our sales and gross profit will be negatively impacted. In addition, wehave assets and liabilities denominated in non-functional currencies which are remeasured at each reporting period, with the offset to changes presented as acomponent of Other (Expenses) Income. Significant non-functional balances include accounts receivable due from a sub-section of our internationalcustomers.INTEREST RATE RISKOn November 7, 2016, we entered into the Credit Agreement which provides for a $100 million senior secured Term Loan and a $150 millionRevolving Facility. Interest on both the Term Loan and Revolving Facility is based on a base rate or Eurodollar rate plus an applicable margin whichincreases as our total leverage ratio increases, with the base rate and Eurodollar rate having ranges of 0.50% to 1.25% and 1.50% to 2.25% respectively. In theevent of default, the interest rate may be increased by 2.0%. A 50 basis point (0.50%) increase or decrease in the interest rate would result approximately in a$2.0 million increase or decrease in interest expense over the life of the agreement.CONCENTRATION OF CREDIT RISKFinancial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cashequivalents, our credit facility and trade accounts receivable.The Company maintains cash and cash equivalents at various institutions and performs periodic evaluations of the relative credit standings of thesefinancial institutions to ensure their credit worthiness. In addition, the Credit Agreement is structured across five above investment grade banks. TheCompany has the ability to draw equally amongst the five banks which limits the concentration of credit risk of one institution.Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers that purchase products from theCompany. No single customer represents more than 10% of total sales. The Company monitors the creditworthiness of its customers to which it grants creditterms in the normal course of business. Although the Company does not currently foresee a significant credit risk associated with the outstanding accountsreceivable, repayment is dependent upon the financial stability of our customers.Item 8.Financial Statements and Supplementary Data.Financial statements and supplementary data required by Part II, Item 8 are included in Part IV of this report as indexed as Item 15 (a) (1) and (2) of thisreport, and are incorporated by reference into this Item 8.

Internal controlover financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a processdesigned by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, management andother personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for externalpurposes in accordance with accounting principles generally accepted in the United States and includes those policies and procedures that:•Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;•Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accountingprinciples generally accepted in the United States, and that our receipts and expenditures are being made only in accordance with authorizations ofour management and members of our board of directors; and•Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have amaterial effect on our financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of anyevaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degreeof compliance with the policies or procedures may deteriorate.Our management has assessed the effectiveness of our internal control over financial reporting as of May 31, 2017. In making this assessment,management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-IntegratedFramework (2013). Based on this evaluation, management concluded that our internal control over financial reporting was effective as of May 31, 2017.The effectiveness of our internal control over financial reporting as of May 31, 2017 has been audited by Deloitte & Touche LLP, an independentregistered public accounting firm, as stated in their report which appears herein.Changes in Internal Control over Financial Reporting There was no change in our internal control over financial reporting for the fiscal quarter ended May 31, 2017 other than items described belowrelated to our remediation actions, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.Remediation of Prior Material Weakness in Internal Control Over Financial ReportingManagement of the Company previously identified and disclosed the following material weakness that existed as of May 31, 2016.We did not design and maintain effective internal controls over the accounting for the annual goodwill impairment test. Specifically, we did notdesign and maintain effective controls to review in sufficient detail the cash flow projections and significant valuation model assumptions used in thegoodwill impairment test as of December 31, 2015. During 2017, management of the Company was actively engaged in remediation efforts to address the material weakness noted above. Thefollowing actions were taken:•The design of the annual goodwill impairment test control was updated to ensure the sufficiency of the control procedures. Specifically, if thediscounted cash flow method is required for performing the goodwill impairment test, detailed procedures over the cash flow projections andvaluation model assumptions are appropriately detailed to instruct the operating effectiveness of the control.52•Sufficient documentation was prepared, reviewed and retained over the goodwill impairment test performed as of December 31, 2016.Based upon the significant actions taken and the testing and evaluation of the effectiveness of our internal control over financial reporting,management of the Company has concluded the material weakness in the Company’s controls no longer existed as of May 31, 2017.53Report of Independent Registered Public Accounting FirmTo the Board of Directors and Stockholders ofAngioDynamics, Inc.Latham, New YorkWe have audited the internal control over financial reporting of AngioDynamics, Inc. and subsidiaries (the "Company") as of May 31, 2017, based on criteriaestablished in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. TheCompany's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internalcontrol over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is toexpress an opinion on the Company's internal control over financial reporting based on our audit.We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all materialrespects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testingand evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considerednecessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal executive and principalfinancial officers, or persons performing similar functions, and effected by the company's board of directors, management, and other personnel to providereasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withgenerally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to themaintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) providereasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally acceptedaccounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management anddirectors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition ofthe company's assets that could have a material effect on the financial statements.Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override ofcontrols, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of theeffectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because ofchanges in conditions, or that the degree of compliance with the policies or procedures may deteriorate.In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of May 31, 2017, based on the criteriaestablished in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financialstatements and financial statement schedule as of and for the year ended May 31, 2017 of the Company and our report dated August 4, 2017 expressed anunqualified opinion on those consolidated financial statements and financial statement schedule./s/ Deloitte & Touche LLPBoston, MassachusettsAugust 4, 201754Item 9B.Other Information.None.55Part IIICertain information required by Part III is omitted from this Annual Report on Form 10-K because we will file a definitive proxy statement within 120days after the end of our fiscal year end pursuant to Regulation 14A (the “Proxy Statement”) for our annual meeting of Stockholders, currently scheduled forOctober 2017.

BASIS OF PRESENTATION, BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESBasis of Presentation and Description of BusinessThe consolidated financial statements include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, (collectively, the “Company”).The Company designs, manufactures and sells a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascularaccess, for the treatment of peripheral vascular disease and in oncology and surgical settings. The devices are generally used in minimally invasive, image-guided procedures. Most of the Company's products are intended to be used once and then discarded, or they may be temporarily implanted for short- orlong-term use.Accounting PrinciplesThe consolidated financial statements and accompanying notes have been prepared in conformity with accounting principles generally accepted in theUnited States of America ("GAAP").Principles of ConsolidationThe consolidated financial statements include the accounts of AngioDynamics and it subsidiaries (all of which are wholly owned). All intercompanybalances and transactions have been eliminated.Use of EstimatesThe preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America, requiresmanagement to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities atthe date of the consolidated financial statements. Estimates also affect reported amounts of sales and expenses during the reporting period. Actual resultscould differ from those estimates.ReclassificationsCertain reclassifications have been made to conform the prior year consolidated financial statements and notes to the current year presentation. Theseinclude a reclassification of bad debt expense from Sales and Marketing to General and Administrative. The amount of the reclassification related to fiscalyear 2016 is $1.0 million and fiscal year 2015 is $0.9 million. The adoption of ASC Update No. 2015-03 resulted in a reclassification of $0.9 million fromother assets to long-term debt in the Company's consolidated balance sheet as of May 31, 2016.Cash and Cash EquivalentsThe Company considers all unrestricted highly liquid investments with an initial maturity of less than three months at the date of purchase to be cashequivalents. The Company maintains cash and cash equivalent balances with financial institutions in the United States in excess of amounts insured by theFederal Deposit Insurance Corporation.Marketable SecuritiesMarketable securities, which include auction rate investments, are classified as “available-for-sale securities” and are reported at fair value, withunrealized gains and losses excluded from operations and reported as a component of accumulated other comprehensive income (loss), net of the related taxeffects, in stockholders’ equity. Cost is determined using the specific identification method. The Company holds investments in auction rate securities inorder to generate higher than typical money market rate investment returns. Auction rate securities typically are high credit quality, generally achieved withmunicipal bond insurance. As of May 31, 2017 and 2016, the Company had $1.2 million and $1.7 million, respectively, in investments in two auction ratesecurities issued by New York state and local government authorities that failed auctions. The authorities are current in their interest payments on thesecurities.66Fair Value InstrumentsThe carrying amount of the Company's cash and cash equivalents, accounts receivable, accounts payable and long-term debt approximates fair valuedue to the short-term nature or market interest rates of these items. The Company bases the fair value of short-term investments on quoted market prices orother relevant information generated by market transactions involving identical or comparable assets. The Company measures and records derivativefinancial instruments at fair value. See Note 3 for further discussion of financial instruments that are carried at fair value on a recurring and nonrecurring basis.Accounts ReceivableAccounts receivable, principally trade receivables, are generally due within 30 to 90 days and are stated at amounts due from customers, net of anallowance for estimated sales returns and doubtful accounts. The Company performs ongoing credit evaluations of customers and adjusts credit limits basedupon payment history and the customer’s current creditworthiness, as determined by a review of their current credit information. The Company continuouslymonitors aging reports, collections and payments from customers, and a provision for estimated credit losses is maintained based upon historical experienceand any specific customer collection issues that have been identified. While such credit losses have historically been within expectations and the provisionsestablished, the Company cannot guarantee that the same credit loss rates will be experienced in the future. The Company writes off accounts receivablewhen they are determined to be uncollectible.InventoriesInventories are stated at the lower of cost (using the first-in, first-out method) or market. Appropriate consideration is given to deterioration,obsolescence, expiring and other factors in evaluating net realizable value.Property, Plant and EquipmentProperty, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over theestimated useful lives of the assets. Refer below for useful lives by category: Estimated useful livesBuilding and building improvements 39 yearsMachinery and equipment 3 to 8 yearsComputer software and equipment 3 to 10 yearsThe Company evaluates property, plant and equipment for impairment periodically to determine if changes in circumstances or the occurrence of eventssuggest the carrying value of the asset or asset group may not be recoverable. Expenditures for repairs and maintenance are charged to expense as incurred.Renewals and betterments are capitalized.Goodwill and Intangible AssetsIntangible assets other than goodwill and acquired IP R&D are amortized over their estimated useful lives, which range between two and eighteenyears, on either a straight-line basis over the expected period of benefit or as revenues are earned from the sales of the related products. The Companyperiodically reviews the estimated useful lives of intangible assets and review such assets for impairment whenever events or changes in circumstancesindicate that the carrying value of the asset or asset group is not recoverable. The Company determines the fair value of the reporting unit based on themarket valuation approach or the income approach. If an intangible asset or asset group is considered to be impaired, the amount of the impairment will equalthe excess of the carrying value over the fair value of the asset.Acquired IP R&D has an indefinite life and is not amortized until completion of the development of the project, at which time the IP R&D becomes anamortizable asset. If the related project is not completed in a timely manner or the project is terminated or abandoned, the Company may have an impairmentrelated to the IP R&D, calculated as the excess of the asset’s carrying value over its fair value.The Company's policy defines IP R&D as the value assigned to those projects for which the related products have not received regulatory approval andhave no alternative future use. Determining the portion of the purchase price allocated to IP R&D requires us to make significant estimates. The amount of thepurchase price allocated to IP R&D is determined by estimating the future cash flows of each project or technology and discounting the net cash flows backto their present values.67The discount rate used is determined at the time of measurement in accordance with accepted valuation methods. These methodologies include considerationof the risk of the project not achieving commercial feasibility.Goodwill is the amount by which the cost of acquired net assets in a business combination exceeded the fair value of net identifiable assets on the dateof purchase. Goodwill and other intangible assets that have indefinite useful lives are not amortized, but rather, are tested for impairment annually or morefrequently if impairment indicators arise.For goodwill, the impairment test requires a comparison of the estimated fair value of the reporting unit to which the goodwill is assigned to carryingvalue of the assets and liabilities of that reporting unit. The determination of reporting units also requires management judgment. The Company considerswhether a reporting unit exists within a reportable segment based on the availability of discrete financial information. If carrying value of the reporting unitexceeds the fair value of the reporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment tothe goodwill balance, resulting in an impairment charge. The Company utilizes either discounted cash flow models or other valuation models, such ascomparative transactions and market multiples, to determine the fair value of our reporting unit. The Company makes assumptions about future cash flows,future operating plans, discount rates, comparable companies, market multiples, purchase price premiums and other factors in those models. Differentassumptions and judgment determinations could yield different conclusions that would result in an impairment charge to income in the period that suchchange or determination was made.Contingent ConsiderationThe fair value of the liability for contingent consideration recorded on the acquisition date for a business combination is based on probability weightedestimated cash flow streams, discounted back to present value using a discount rate determined in accordance with accepted valuation methods and reflectiveof the risk associated with the estimated cash flow streams. The liability for contingent consideration is remeasured to fair value at each reporting period withchanges recorded in earnings until the contingency is resolved.Revenue RecognitionThe Company recognizes revenue when the following four criteria has been met: (i) persuasive evidence that an arrangement exists; (ii) the price isfixed or determinable; (iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. The Companyrecognizes revenue, net of sales taxes assessed by any governmental authority, as products are shipped, based on shipping terms, and when title and risk ofloss passes to customers. The Company negotiates shipping and credit terms on a customer-by-customer basis and products are shipped at an agreed uponprice. All product returns must be pre-approved by the Company and customers may be subject to a 20% restocking charge. To be accepted, a returnedproduct must be unadulterated, undamaged and have at least twelve months remaining prior to its expiration date. Charges for discounts, returns, rebates andother allowances are recognized as a deduction from revenue on an accrual basis in the period in which the revenue is recorded. The accrual for productreturns, discounts and other allowances is based on the Company’s history.Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognizedwhen the related finished product is shipped to the customer. Amounts charged to customers for shipping are recorded in net sales.Research and DevelopmentResearch and development costs, including salaries, consulting fees, building costs, utilities and administrative expenses that are related to developingnew products, enhancing existing products, validating new and enhanced products, managing clinical, regulatory and medical affairs are expensed asincurred.68Income TaxesThe Company calculates income tax expense for each jurisdiction in which it operates. This involves estimating actual current taxes due plus assessingtemporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. The Companyperiodically evaluates deferred tax assets, capital loss carryforwards and tax credit carryforwards to determine their recoverability based primarily on theCompany's ability to generate future taxable income and capital gains. Where it is more-likely-than-not these will not be recovered, the Company estimates avaluation allowance and records a corresponding additional tax expense in the consolidated statement of operations.The Company recognizes and measures uncertain tax positions taken or expected to be taken in a tax return utilizing a two-step approach. TheCompany first determines if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit,including resolution of any related appeals or litigation processes. The second step is that the Company measures the tax benefit as the largest amount that ismore likely than not to be realized upon ultimate settlement. The Company recognizes interest and penalties related to uncertain tax positions in theprovision for income taxes on the consolidated statements of operations.Warranty CostsThe Company makes periodic provisions for expected warranty costs. Historically, warranty costs have been insignificant.Stock Based CompensationStock-based compensation expense reflects the fair value of stock-based awards measured at the grant date and recognized over the relevant serviceperiod. The Company estimates the fair value of each stock-based award on the measurement date using either the current market price of the stock, theBlack-Scholes option valuation model, or the Monte Carlo Simulation valuation model. The Black-Scholes and Monte Carlo Simulation valuation modelsincorporate assumptions as to stock price volatility, the expected life of options or restricted stock units, a risk-free interest rate and dividend yield. TheCompany recognizes stock-based compensation expense related to options, restricted stock units and market based performance stock units on a straight-linebasis over the service period of the award, which is generally 4 years for options and restricted stock units and 3 years for market based performance stockunits.Foreign Currency TranslationThe functional currency of most of the Company's foreign subsidiaries is the local currency in which the subsidiary operates. For foreign operationswhere the local currency is considered to be the functional currency, the Company translates assets and liabilities into U.S. dollars at the exchange rate on thebalance sheet date. The Company translates income and expense items at average rates of exchange prevailing during each period. The Companyaccumulates translation adjustments in accumulated other comprehensive loss, a component of stockholders’ equity.For foreign operations where the U.S. dollar is considered to be the functional currency, the Company remeasures monetary assets and liabilities intoU.S. dollars at the exchange rate on the balance sheet date and non-monetary assets and liabilities are remeasured into U.S. dollars at historical exchangerates. The Company translates income and expense items at average rates of exchange prevailing during each period. The Company recognizesremeasurement adjustments as a component of other expense in the consolidated statements of operations.Transaction gains or losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency areincluded in other expense in the statements of operations as incurred.Derivative Financial InstrumentsThe Company is exposed to market risks, including changes in foreign currency and interest rates. The Company periodically enters into certainderivative financial instruments to hedge the underlying economic exposure.Derivative instruments are presented in the consolidated financial statements at their fair value. Changes in the fair value of derivative financialinstruments are either recognized periodically in income or in stockholders’ equity as a component of accumulated other comprehensive income (loss)depending on whether the derivative financial instrument qualifies for hedge accounting and, if so, whether it qualifies as a fair value or cash flow hedge.Generally, the changes in the fair value of derivatives accounted for as fair value hedges are recorded in income along with the portions of the changes in thefair value of hedged items that relate to the hedged risks. Changes in the fair value of derivatives accounted for as cash flow hedges, to the extent they areeffective as hedges, are recorded in accumulated other comprehensive income (loss).ContingenciesThe Company is subject to various legal proceedings that arise in the ordinary course of business, including patent infringement and product liabilitymatters. The Company records accruals for contingencies when it is probable the liability has been incurred and the amount can be reasonably estimated.Legal fees are expensed as incurred. Insurance recoveries related to potential claims are recognized up to the amount of the recorded liability when coverageis confirmed and the estimated recoveries are probable of payment. These recoveries are not netted against the related liabilities for financial statementpresentation.Recently Issued Accounting Pronouncements - AdoptedIn April 2015, the Financial Accounting Standards Board ("FASB") issued ASC Update No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30):Simplifying the Presentation of Debt Issuance Costs. Update No. 2015-03 requires debt issuance costs related to a recognized debt liability to be presented inthe balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Update No. 2015-03 is effective forannual reporting periods beginning after December 15, 2015 and interim periods within those reporting periods. This was adopted in the first quarter of fiscal2017 and the Company reclassified $0.9 million from other assets to long-term debt, net in the balance sheet as of May 31, 2016.Recently Issued Accounting Pronouncements - Not Yet Applicable or AdoptedIn May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09). ASU 2014-09 provides a single,comprehensive accounting model for revenues arising from contracts with customers that supersedes most of the existing revenue recognition guidance,including industry-specific guidance. Under this model, revenue is recognized at an amount that an entity expects to be entitled to upon transferring controlof goods or services to a customer, as opposed to when risks and rewards transfer to a customer under existing revenue recognition guidance. ASU 2014-09 iseffective for the Company beginning in its fiscal year 2019, and may be applied retrospectively to all prior periods presented or through a cumulativeadjustment to the opening retained earnings balance in the year of adoption. The Company is currently in the process of evaluating the impact of ASU 2014-09 on its consolidated financial statements.In July 2015, the FASB issued ASC Update No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. Update No. 2015-11more closely aligns the measurement of inventory in U.S. GAAP with the measurement of inventory in International Financial Reporting Standards byrequiring companies using the first-in, first-out and average costs methods to measure inventory using the lower of cost and net realizable value, where netrealizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, andtransportation. Update No. 2015-11 is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those fiscal years.Update No. 2015-11 should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. Theadoption of Update No. 2015-11 is not expected to have a material impact on the Company's financial position or results of operations.In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 increases transparency and comparability among organizationsby recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. For leases with a term or twelvemonths or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities. ASU2016-02 is effective for fiscal years beginning after December 15, 2018 and early application is permitted. The Company is currently in the process ofevaluating the impact of ASU 2016-02 on its consolidated financial statements.In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Based Compensation (Topic 718: Improvements to Employee Share-BasedPayment Accounting). ASU 2016-09 simplifies and improves various aspects of ASC 718 for share-based payments, including income tax items and theclassification of these items on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 31, 2016 and earlyapplication is permitted. The Company is currently in the process of evaluating the impact of ASU 2016-09 on its consolidated financial statements.In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and CashPayments (ASU 2016-15). ASU 2016-15 identifies how certain cash receipts and cash payments are presented and classified in the Statement of Cash Flowsunder Topic 230. ASU 2016-15 is effective for the Company for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years.ASU 2016-15 should be applied retrospectively and early adoption is permitted, including adoption in an interim period. The Company is currently in theprocess of evaluating the impact of ASU 2016-15 on its consolidated financial statements.In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), which simplifies the subsequent measurement ofgoodwill by eliminating steps from the goodwill impairment test. ASU 2017-04 should be adopted for annual or interim goodwill impairment tests in fiscalyears beginning after December 15, 2019. ASU 2017-04 should be applied prospectively and early adoptions is permitted, including adoption in an interimperiod. The Company is currently evaluating the impact of ASU 2017-04 on its consolidated financial statements.692. OTHER ASSETSIn 2015, the Company filed an 8-K stating that it executed a non-binding letter of intent to enter into a strategic relationship with privately-heldEmboMedics Inc., which develops injectable and resorbable embolic microspheres.The Company made an initial $2.0 million purchase of non-transferable warrants in a subsidiary of EmboMedics which become exercisable upon achange of control of EmboMedics. The Company did not have significant influence, or control of the subsidiary. This initial investment was recorded at costand the Company reviewed for impairment at each balance sheet date.In the second quarter of fiscal year 2017, the Company decided to terminate its agreements with EmboMedics. The termination of these agreementsresulted in a write-off of the initial $2.0 million investment in EmboMedics which is included in acquisition, restructuring and other items, net on theconsolidated statements of operations.3. FAIR VALUE OF FINANCIAL INSTRUMENTSOn a recurring basis, the Company measures certain financial assets and financial liabilities at fair value based upon quoted market prices, whereavailable. Where quoted market prices or other observable inputs are not available, the Company applies valuation techniques to estimate fair value. FASBASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. Thecategorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to themeasurement of fair value. The three levels of the hierarchy are defined as follows:•Level 1 - Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.•Level 2 - Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.•Level 3 - Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants woulduse in pricing the asset or liability at the measurement date, including assumptions about risk.The Company's financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable and contingentconsideration. The carrying amount of cash and cash equivalents, accounts receivable, and accounts payable approximates fair value due to their immediateor short-term maturities. The recurring fair value measurements using significant unobservable inputs (Level 3) relate to marketable securities, which arecomprised of auction rate securities, and contingent consideration liabilities. 70The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis: Fair Value Measurementsusing inputs considered as: (in thousands)Level 1 Level 2 Level 3 Fair Value at May31, 2017Financial Assets Marketable securities$— $— $1,215 $1,215Total Financial Assets$— $— $1,215 $1,215Financial Liabilities Contingent liability for acquisition earn outs$— $— $12,761 $12,761Total Financial Liabilities$— $— $12,761 $12,761 Fair Value Measurementsusing inputs considered as: (in thousands)Level 1 Level 2 Level 3 Fair Value at May31, 2016Financial Assets Marketable securities$— $— $1,653 $1,653Total Financial Assets$— $— $1,653 $1,653Financial Liabilities Contingent liability for acquisition earn outs$— $— $38,275 $38,275Total Financial Liabilities$— $— $38,275 $38,275There were no transfers in and out of Level 1, 2 and 3 measurements for the years ended May 31, 2017 and 2016.The table below presents the changes in fair value components of Level 3 instruments in the year ended May 31, 2017 (in thousands of dollars):Financial Assets Financial Liabilities(in thousands)Fair Value MeasurementsUsing SignificantUnobservable Inputs(Level 3) Fair Value MeasurementsUsing SignificantUnobservable Inputs (Level 3)Balance at May 31, 2016$1,653 $38,275Change in fair value of contingent consideration, net (1)— (15,261)Currency (gain) loss from remeasurement— (153)Fair market value adjustments12 —Sale of securities(450) —Contingent consideration payments— (10,100)Balance at May 31, 2017$1,215 $12,761The Company made the decision to discontinue its investment in the TiLo product that was acquired in August 2013 as part of the Clinical Devicesacquisition. This decision resulted in the write-off of the acquired in-process research and development (IPR&D) of $3.6 million along with a $3.1 milliongain from the reduction in the fair value of contingent consideration liability associated with future milestones that will no longer be met. The write-off of theIPR&D is included in acquisition, restructuring and other, net on the consolidated statement of operations.The Company revised the sales projections for the AngioVac product as a result of reviews performed by executive management across all products. Theadjustments to the sales projections resulted in a $13.4 million gain from the reduction in the fair value of the contingent liability that is based on lowerprojected sales volume over the contractual earn out period.71The Company decided to terminate its agreement with EmboMedics which resulted in a $2.0 million write-off of our investment in EmboMedics (Note2).The table below presents the changes in fair value components of Level 3 instruments in the year ended May 31, 2016 (in thousands of dollars): Financial Assets Financial Liabilities(in thousands)Fair Value MeasurementsUsing SignificantUnobservable Inputs(Level 3) Fair Value MeasurementsUsing SignificantUnobservable Inputs (Level 3)Balance at May 31, 2015$1,689 $47,384Change in fair value of contingent consideration (1)— 948Currency (gain) loss from remeasurement— 43Fair market value adjustments(36) —Contingent consideration payments— (10,100)Balance at May 31, 2016$1,653 $38,275(1) Change in the fair value of contingent consideration is included in earnings and comprised of changes in estimated earn out payments based onprojections of company performance and amortization of the present value discount.Marketable SecuritiesMarketable securities consist solely of an auction rate security. Assumptions associated with the auction rate security include the interest ratebenchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required byinvestors to own such securities given the current liquidity risk.Contingent Liability for Acquisition Earn OutsCertain business combinations involve the potential for the payment of future contingent consideration upon the achievement of certain productdevelopment milestones and/or various other favorable operating conditions. Payment of the additional consideration is generally contingent on theacquired company reaching certain performance milestones, including attaining specified revenue levels or achieving product development targets.Contingent consideration is recorded at the estimated fair value of the contingent milestone payments on the acquisition date. The fair value of thecontingent milestone consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income orexpense within change in fair value of contingent consideration in the consolidated statement of operations.Contingent consideration liabilities will be remeasured to fair value each reporting period using projected net sales, discount rates, probabilities ofpayment and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model.Projected net sales are based on internal projections and extensive analysis of the target market and the sales potential. Increases in projected net sales andprobabilities of payment may result in higher fair value measurements in the future. Increases in discount rates and the projected time to payment may resultin lower fair value measurements in the future. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fairvalue measurement in the future.The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant unobservable inputs as ofMay 31, 2017: (in thousands)Fair value atMay 31, 2017 ValuationTechnique UnobservableInput RangeRevenue based payments$12,761 Discounted cash flow Discount rateProbability of paymentProjected fiscal year of payment 4%100%2018 - 202272At May 31, 2017, the estimated potential amount of undiscounted future contingent consideration that the Company expects to pay as a result of allcompleted acquisitions is approximately $13.1 million, which represents the remaining contractual minimum payments.734.

The Company makes assumptions about the future demand for and marketvalue of the inventory. Based on these assumptions, the Company estimates the amount of obsolete, expiring and slow moving inventory. The totalinventory reserve at May 31, 2017 and 2016 was $7.3 million and $12.6 million, respectively. Of the $7.3 million, $2.4 million relates to the inventoryreserve for Acculis inventory as a result of the recall (Note 10). Of the $12.6 million in the prior year, $5.8 million relates to the reserve of Celerity inventoryon-hand at May 31, 2016.6.

GOODWILL AND INTANGIBLE ASSETSIntangible assets other than goodwill are amortized over their estimated useful lives on either a straight-line basis or proportionately to the benefitbeing realized. Useful lives range from two to eighteen years. The Company periodically reviews the estimated useful lives of intangible assets and reviewsuch assets or asset groups for impairment whenever events or changes in circumstances indicate that the carrying value of the assets or asset groups may notbe recoverable. If an intangible asset or asset group is considered to be impaired, the amount of the impairment will equal the excess of the carrying valueover the fair value of the asset.Goodwill is not amortized, but rather, is tested for impairment annually or more frequently if impairment indicators arise. Goodwill represents theexcess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination.The Company's annual testing for impairment of goodwill was completed as of December 31, 2016. The Company operates as a single operatingsegment with one reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole.The Company determines the fair value of the reporting unit based on the market valuation approach and concluded that it was not more-likely-than-not thatthe fair value of the Company's reporting unit was less than its carrying value.Even though the Company determined that there was no goodwill impairment as of December 31, 2016, the future occurrence of a potential indicator ofimpairment, such as a significant adverse change in legal, regulatory, business or economic conditions or a more-likely-than-not expectation that thereporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interim assessment for the reporting unit prior to thenext required annual assessment as of December 31, 2017. The Company continued to assess for potential impairment through May 31, 2017 and noted noevents that would be considered a triggering event. There were no adjustments to goodwill for the years ended May 31, 2017 and 2016. As of May 31, 2017 and 2016, intangible assets consisted of the following: May 31, 2017 Gross carryingvalue Accumulatedamortization Net carryingvalue(in thousands) Product technologies$147,172 $(59,696) $87,476Customer relationships56,375 (19,194) 37,181Trademarks28,400 (9,069) 19,331Licenses4,487 (3,821) 666Distributor relationships1,250 (229) 1,021 $237,684 $(92,009) $145,675 May 31, 2016 Gross carryingvalue Accumulatedamortization Net carryingvalue(in thousands) Product technologies$148,387 $(51,313) $97,074Customer relationships88,389 (47,133) 41,256Trademarks28,470 (6,242) 22,228Licenses7,931 (6,716) 1,215Distributor relationships2,150 (946) 1,204In process R&D3,600 — 3,600 $278,927 $(112,350) $166,57777Amortization expense was $17.3 million, $18.0 million and $18.0 million for fiscal years 2017, 2016 and 2015, respectively.Annual amortization of these intangible assets is expected to approximate the following amounts for each of the next five fiscal years: (in thousands) 2018$16,500201916,132202014,578202113,627202212,9522023 and thereafter71,886 $145,6759. INCOME TAXESThe components of income (loss) before income tax expense (benefit) for the years ended May 31 are as follows: 2017 2016 2015(in thousands) Income (loss) before tax expense: US$8,825 $(4,444) $(8,965)Non-US1,022 1,191 834 $9,847 $(3,253) $(8,131) Income tax expense (benefit) is comprised of the following: 2017 2016 2015(in thousands) Current Federal$— $34 $(242)State and local141 103 205Non U.S.270 217 417 411 354 380Deferred4,428 39,983 (5,123)Income tax expense (benefit)$4,839 $40,337 $(4,743)In the fiscal years 2017 and 2016 income tax expense, the Company recorded tax expense of $4.8 million and $40.3 million, respectively, primarilydriven by the impact of recording a deferred tax liability related to the amortization of intangibles, for tax purposes, that have an indefinite reversal periodand cannot be used to support the deferred tax assets in fiscal 2017 and recording a valuation allowance of $40.4 million on the U.S. deferred tax assets infiscal 2016.In the fiscal year 2015 income tax benefit, the Company recorded a tax benefit of $4.7 million, primarily driven by a benefit of the $9.2 millionnontaxable adjustment to the contingent liabilities related to Vortex Medical and Clinical Devices, and a seven month benefit from the R&D tax credit thatexpired on December 31, 2014, offset by non-deductible interest expense related to contingent payments, true-ups of our fiscal year 2014 US income taxreturns and the impact of the elimination of the ASC 718 APIC pool.78Temporary differences that give rise to deferred tax assets and liabilities are summarized as follows: May 31, 2017 May 31, 2016(in thousands) Deferred tax assets Net operating loss carryforward$55,975 $52,593Stock-based compensation2,653 4,135Federal and state R&D tax credit carryforward2,548 2,145Inventories2,407 4,535Expenses incurred not currently deductible6,522 3,018Accrued liabilities1,289 339Gross deferred tax asset71,394 66,765Deferred tax liabilities Excess tax over book depreciation and amortization49,158 46,240 49,158 46,240Valuation Allowance(48,348) (42,209)Net deferred tax liability$(26,112) $(21,684)The Company's Federal net operating loss carryforwards as of May 31, 2017 after considering IRC Section 382 limitations are $161.6 million. Theexpiration of the Federal net operating loss carryforwards are as follows: $29.8 million between 2017 and 2023 and $131.8 million between 2027 and 2037.The Company's state net operating loss carryforwards as of May 31, 2017 after considering remaining IRC Section 382 limitations are $32.7 millionwhich expire in various years from 2017 to 2037.As a result of certain realization requirements of ASC 718, the table of deferred tax assets and liabilities shown above does not include certain deferredtax assets as of May 31, 2017 and 2016 that arose directly from tax deductions related to equity compensation greater than compensation recognized forfinancial reporting. Equity will be increased by $0.6 million if and when such excess tax benefits are ultimately realized.A valuation allowance is provided if based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assetswill not be realized. After careful consideration and weighing of all the available positive and negative evidence, the weight given to the threeyear cumulative loss and lack of a recent history of core earnings was difficult to overcome and a full valuation allowance related to the U.S. deferred taxassets was established in the period ending May 31, 2016. Management considered all available positive and negative evidence at May 31, 2017, andconsidering the cumulative loss in the U.S. over the three year period, determined that the valuation allowance is still required. Management will continue toreevaluate the positive and negative evidence at each reporting period and if future results as projected in the U.S. and the Company's tax planning strategiesare favorable, the valuation allowance may be removed, which could have a favorable material impact on the Company's results of operations in the period inwhich it is recorded.The net deferred tax liability as of May 31, 2017 and 2016 relates to tax amortization of intangibles that have an indefinite reversal period for bookpurposes and cannot be used to support the deferred tax asset.The Company's consolidated income tax expense has differed from the amount that would be provided by applying the U.S. Federal statutory incometax rate to the Company's income before income taxes for the following reasons:79 For the year ended May 31, 2017 2016 2015(in thousands) Income tax expense (benefit) at statutory tax rate of 35%$3,447 $(1,139) $(2,845)Effect of graduated tax rates(98) 33 81State income taxes, net of Federal tax benefit(22) (215) (21)Impact of Non-US operations403 (162) 133Research and development tax credit(403) (499) (604)Meals and entertainment266 329 —Non-deductible interest on contingent payments174 262 265Non-taxable gain on revaluation of contingent consideration liability(5,576) (170) (3,102)Tax law changes— — (454)Change in valuation allowance6,139 40,685 —Effect of elimination of stock compensation APIC pool1,380 739 1,253IPR&D intangible write-off(1,224) — —Other nondeductible expenses219 207 498Over (under) accrual of prior year Federal and State taxes(3) 356 38Other137 (89) 15Income tax expense (benefit)$4,839 $40,337 $(4,743)The following table provides a reconciliation of the beginning and ending amount of unrecognized tax benefits: For the year ended May 31, 2017 2016 2015(in thousands) Unrecognized tax benefits balance at June 1$899 $— $—Increase in gross amounts of tax positions related to prior years— 899 —Unrecognized tax benefits balance at May 31$899 $899 $—The table above includes unrecognized tax benefits associated with the calculation of limitations placed on the utilization of tax attributes relatedto an acquired company. If recognized, $0.1 million of the balance of unrecognized tax benefits as of May 31, 2017 would affect the effective tax rate and thebalance of $0.8 million would result in adjustments to other tax accounts. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. There are no accruedinterest and penalties recognized in the consolidated balance sheet as of May 31, 2017 and May 31, 2016.The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business theCompany is subject to examination by taxing authorities throughout the world. Fiscal years 2014 through 2017 remain open to examination by the varioustax authorities.The Company does not anticipate that the amount of unrecognized tax benefits will significantly change in the next twelve months.The accumulated undistributed earnings of the Company’s foreign operations were approximately $5.3 million, and are intended to remain indefinitelyinvested in foreign operations. Accordingly, no taxes have been provided on these earnings as of80May 31, 2017. If these earnings were distributed, the Company would be subject to both foreign withholding taxes and U.S. income taxes that may not befully offset by foreign tax credits. A reasonable estimate of the deferred tax liability on these earnings is not practicable at this time.10. ACCRUED LIABILITIESAs of May 31, 2017 and 2016, accrued liabilities consist of the following: May 31,2017 May 31,2016(in thousands) Payroll and related expenses$11,383 $9,414Royalties2,885 2,489Accrued severance2,075 1,524Sales and franchise taxes856 565Outside services1,622 2,063Litigation matters (Note 15)12,500 —Acculis recall liability2,563 —Other4,920 5,887Total$38,804 $21,942In the fourth quarter of fiscal year 2017, the Company issued a voluntary recall of its Acculis probes that were sold over the past two years. As aresult of this voluntary recall, the Company decided to also do a voluntary market withdrawal of its Acculis capital systems and discontinue selling theproduct. The voluntary recall resulted in a deferral of revenue of $2.6 million and an increase of $2.6 million in inventory and hardware asset reserves. Thetotal impact to income before taxes of the recall was $4.5 million.11. LONG-TERM DEBTOn November 7, 2016, the Company entered into a Credit Agreement with the lenders party thereto, JPMorgan Chase Bank, N.A., as administrativeagent, Bank of America, N.A. and Keybank National Association as co-syndication agents, and JPMorgan Chase Bank, N.A., Merrill Lynch, Pierce, Fenner &Smith Incorporated and Keybank National Association as joint bookrunners and joint lead arrangers.The Credit Agreement provides for a $100.0 million senior secured term loan facility and a $150.0 million senior secured revolving credit facility,which includes up to a $20.0 million sublimit for letters of credit and a $5.0 million sublimit for swingline loans.On November 7, 2016, the Company borrowed $100.0 million under the Term Loan and approximately $16.5 million under the Revolving Facility torepay the balance of $116.5 million under the former credit agreement. In February 2017 the revolver was paid off in full. As of May 31, 2017 and 2016 thecarrying value of long-term debt approximates its fair market value.The proceeds of the Revolving Facility may be used for general corporate purposes of the Company and its subsidiaries. The Facilities have a five yearmaturity. Interest on both the Term Loan and Revolving Facility are based on a base rate or Eurodollar rate plus an applicable margin which increases astotal leverage ratio increases, with the base rate and Eurodollar rate having ranges of 0.50% to 1.25% and 1.50% to 2.25% respectively. In case of default, theinterest rate may be increased by 2.0%. The Revolving Facility carries a commitment fee of 0.20% to 0.35% per annum on the unused portion. The interestrate on the Term Loan at May 31, 2017 was 2.55%.The Company's obligations under the Facilities are unconditionally guaranteed, jointly and severally, by the Company's material direct and indirectdomestic subsidiaries (the “Guarantors”).

Subject to preferences applicable to any outstanding shares of preferred stock,the holders of common stock are entitled to receive ratably dividends, if any, as may be declared by the Board of Directors out of funds legally available fordividend payments. If the Company liquidates, dissolves, or winds up, the holders of common stock are entitled to share ratably in all assets remaining afterpayment of liabilities and liquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no pre-emptive rights or rightsto convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to82the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of theholders of shares of any series of preferred stock that the Company may designate in the future.The board of directors has the authority to (i) issue the undesignated preferred stock in one or more series, (ii) determine the powers, preferences andrights and the qualifications, limitations or restrictions granted to or imposed upon any wholly un-issued series of undesignated preferred stock and (iii) fixthe number of shares constituting any series and the designation of the series, without any further vote or action by the Company's stockholders.Stock Options2004 Stock and Incentive Award PlanThe 2004 Stock and Incentive Award Plan (the “2004 Plan”) provides for the grant of incentive options to employees and for the grant of non-statutorystock options, restricted stock, stock appreciation rights, performance units, performance shares and other incentive awards to employees, directors and otherservice providers. A total of 7,000,000 shares of common stock have been reserved for issuance under the 2004 Plan, of which up to 800,000 shares may beissued upon the exercise of incentive stock options. The compensation committee of the Board of Directors administers the 2004 Plan. The committeedetermines vesting terms and the exercise price of options granted under the 2004 Plan, but for all incentive stock options the exercise price must at least beequal to the fair market value of common stock on the date of grant. The term of an incentive stock option may not exceed ten years.On October 25, 2016, the Company amended the 2004 Stock and Incentive Award Plan to increased the shares of common stock reserved for issuanceby 250,000 shares.As of May 31, 2017, there remained approximately 2.4 million shares available for granting under the 2004 Plan. The following table summarizes information about stock option activity for the fiscal year ended May 31, 2017. 2017 Shares Weighted-averageexerciseprice Weightedaverageremainingcontractuallife Aggregateintrinsicvalue (inthousands)Outstanding at beginning of year2,281,618 $14.45 Granted667,691 $16.83 Exercised(826,286) $13.45 Forfeited(342,924) $16.03 Expired(112,656) $19.08 Outstanding at end of year1,667,443 $15.01 4.66 $1,513Options exercisable at year-end659,463 $14.26 2.88 $913Options expected to vest in future periods884,906 $15.50 5.83 $527Stock options are granted at exercise prices equal to the quoted market price of common stock at the date of the grant. Options vest 25% per year overfour years for employees and 100% after one year for consultants. Grants to directors vest 33.33% per year over three years. Stock options granted prior toMay 1, 2007 expire on the tenth anniversary of the grant date. Stock options granted on or after May 1, 2007, expire on the seventh anniversary of the grantdate.The Company measures the fair value of each stock option grant at the date of grant using a Black-Scholes option pricing model. The weighted averagegrant-date fair value of options granted during the years ended May 31, 2017, 2016 and 2015 was $4.70, $4.16, and $4.74, respectively. The followingassumptions were used in arriving at the fair value of options granted during 2017, 2016 and 2015, respectively: risk-free interest rates of 1.30%, 1.48% and1.54%; expected volatility of 31%, 31%, and 31%; and expected lives of 4.80 years, 4.81 years, and 4.76 years. The Company does not declare dividendstherefore a dividend yield of zero was used for the years ended May 31, 2017, 2016 and 2015. Risk-free interest rates reflect the yield on83zero-coupon U.S. Treasury bonds whose maturity period equals the expected term of the option. Expected volatilities are based on the historical volatility ofthe Company's stock. The expected option lives are based on historical experience of employee exercise behavior.The total intrinsic value of options exercised during the years ended May 31, 2017, 2016 and 2015 was $2.8 million, $0.1 million, and $1.6 million,respectively. As of May 31, 2017, there was $3.7 million of total unrecognized compensation cost related to non-vested options, which is expected to berecognized over a weighted average period of 3 years.Cash received from option exercises during 2017, 2016 and 2015 was $9.9 million, $1.3 million and $4.3 million, respectively. The tax benefit realizedfrom stock options exercised during the years ended May 31, 2016 and 2015 were $0.1 million and $0.5 million, respectively. Due to the valuationallowance there was no tax benefit realized from stock option exercises during the year ended May 31, 2017.Performance Share and Restricted Stock Unit AwardsThe Company grants restricted stock units to certain employees under the 2004 Plan which give the recipients the right to receive shares of Companystock upon vesting. The restricted stock unit awards vest in equal annual installments over the term of the grants. Unvested restricted stock unit awards willbe forfeited if the recipient ceases to be employed by the Company. The following table summarizes information about restricted stock unit activity for the year ended May 31, 2017.

The weighted average grant date fair value ofrestricted stock units granted during the years ended May 31, 2017, 2016 and 2015 was $16.54, $15.21 and $14.75, respectively. The total intrinsic value ofrestricted stock units (meaning the fair value of the units on the date of vest) vesting during the years ended May 31, 2017, 2016 and 2015 was $2.9 million,$2.5 million, and $2.4 million, respectively. As of May 31, 2017, there was $4.9 million of total unrecognized compensation cost related to non-vestedrestricted stock awards, which is expected to be recognized over a weighted average period of 3 years.The Company grants performance share awards to certain employees under the 2004 Plan which gives the recipients the right to receive shares ofCompany stock if certain criteria is met. The performance criteria is established by the compensation committee for vesting of the performance share awardsand may include factors such as the achievement of relative total shareholder return ("TSR"), certain sales, operating income and earnings per share (“EPS”)goals. Performance share awards are subject to additional conditions, including the recipient’s continued employment with the Company. The following table summarizes information about performance unit award activity for the year ended May 31, 2017.

Vesting of the performanceunit awards is based on the Company's level of attainment of specified total shareholder return ("TSR") targets relative to the percentage appreciation of aspecified index of companies for the respective three-year periods. It is also subject to the continued employment of the grantees. In order to estimate the fairvalue of such awards, we used a Monte Carlo Simulation valuation model on the date of the grant. For the years ended May 31, 2017, 2016 and 2015, theweighted average grant date fair market value for new grants was $22.61, $18.07 and $19.83, respectively. Compensation cost is recognized over theperformance period which is typically three years. As of May 31, 2017, 0.4 million performance share units with a weighted average remaining contractualterm of 3 years and $4.2 million of unrecognized compensation cost were outstanding.Compensation ExpenseThe following tables represents the break out of share-based compensation included in the Company's consolidated statement of operations.

The income tax benefit for 2017 and 2016 are negated by the full valuationallowance established as of May 31, 2016.Employee Stock Purchase PlanThe Employee Stock Purchase Plan (the “Stock Purchase Plan”) provides a means by which employees (the “participants”) are given an opportunity topurchase the Company's common stock through payroll deductions. A total of 2,500,000 shares of common stock have been reserved for issuance under theStock Purchase Plan. Shares are offered through two purchase periods, each with duration of approximately 6 months, commencing on the first business dayof the first and third fiscal quarters. An employee is eligible to participate in an offering period if, on the first day of an offering period, he or she has beenemployed in a full-time capacity for at least six months, with a customary working schedule of 20 or more hours per week and more than five months in acalendar year. Employees who own stock possessing 5% or more of the total combined voting power or value of all classes of stock are not eligible toparticipate in the Stock Purchase Plan. The purchase price of the shares of common stock acquired on each purchase date will be the lower of (i) 85% of thefair market value of a share of common stock on the first day of the offering period or (ii) 85% of the fair market value of a share of common stock on the lastday of the purchase period, subject to adjustments made by the Board of Directors. The Stock Purchase Plan is intended to qualify as an “employee stockpurchase plan” within the meaning of Section 423 of the Internal Revenue Code. During the year ended May 31, 2015, an additional 800,000 shares of theCompany's common stock have been reserved for issuance under the Stock Purchase Plan. During the year ended May 31, 2017, an additional 500,000 sharesof the Company's common stock have been reserved for issuance under the Stock Purchase Plan. The Company uses the Black-Scholes option-pricing model to calculate the purchase date fair value of the shares issued under the Stock Purchase Planand recognize expense related to shares purchased ratably over the offering period. During the years ended May 31, 2017, 2016 and 2015, 129,185, 137,957and 119,001 shares, respectively, were issued at an average price of $11.00, $10.67 and $11.89, respectively, under the Stock Purchase Plan. As of May 31,2017, 1.3 million shares remained available for future purchases under the Stock Purchase Plan.85Share RepurchasesOn November 6, 2016, the Board of Directors approved the Repurchase Program under which they authorized the Company the option to repurchase upto $25.0 million of its outstanding common stock during the twenty-four month period ending November 6, 2018.

As of May 31, 2017, $11.4 million remained available for repurchase under the Repurchase Program.In February 2017, the Company retired 642,305 shares of treasury stock. These retired shares are now included in the Company’s pool of authorized butunissued shares. The retired stock had a carrying value of approximately $9.9 million and $0.01 was the par value that was deducted from common stock andthe remaining $9.9 million was deducted from additional paid-in capital.14. EARNINGS PER SHAREBasic earnings per share are based on the weighted average number of common shares outstanding. In addition, diluted earnings per share include thedilutive effect of potential common stock consisting of stock options, restricted stock units and performance stock units, provided that the inclusion of suchsecurities is not anti-dilutive. In periods with a net loss, stock options and restricted stock units are not included in the computation of basic loss per share asthe impact would be anti-dilutive.The following table reconciles basic to diluted weighted average shares outstanding for the years ended May 31, 2017, 2016 and 2015: For the year ended May 31, 2017 2016 2015Basic36,616,859 36,161,383 35,683,139Effect of dilutive securities342,391 — —Diluted36,959,250 36,161,383 35,683,139 Securities excluded as their inclusion would be anti-dilutive1,058,790 3,277,037 2,862,41415.

During fiscal 2017, 2016 and 2015, aggregate rentalcosts under all operating leases were approximately $2.5 million, $2.5 million and $3.4 million, respectively. Future annual payments under non-cancelableoperating leases in the aggregate, of which one includes an escalation clause, with initial remaining terms of more than one year at May 31, 2017, aresummarized as follows (in thousands): 86(in thousands) 2018$2,21420192,06620201,86020211,0252022 and thereafter2,552 $9,717Other Commitments and ContingenciesThe following table summarizes the Company's other future commitments and contingencies as of May 31, 2017.(in thousands)Total 2018 2019 2020 2021 2022 andthereafterPurchase obligations (1)$49,762 $8,443 $8,726 $9,162 $8,709 $14,722Royalties44,000 2,500 3,000 3,500 3,500 31,500Other834 167 167 167 167 166 $94,596 $11,110 $11,893 $12,829 $12,376 $46,388(1)The non-cancelable inventory purchase obligations are not reflected on our consolidated balance sheets under accounting principles generallyaccepted in the United States of America. Legal ProceedingsThe Company is involved in various legal proceedings, including commercial, intellectual property, product liability, and regulatory matters of anature considered normal for its business. The Company accrues for amounts related to these matters if it is probable that a liability has been incurred, and anamount can be reasonably estimated. The Company discloses such matters when there is at least a reasonable possibility that a material loss may have beenincurred. However, the Company cannot predict the outcome of any litigation or the potential for future litigation. C.R. Bard, Inc. v. AngioDynamics, Inc.On January 11, 2012, C.R. Bard, Inc. (“Bard”) filed a suit in the United States District Court of Utah claiming certain of our implantable port productsinfringe on three U.S. patents held by Bard (the "Utah Action"). Bard is seeking unspecified damages and other relief. The Court denied Bard’s motion for pre-trial consolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but had asked forsupplemental briefing on the issue of whether to conduct a common Markman hearing. Meanwhile, we filed petitions for reexamination in the US Patent andTrademark Office ("PTO") which seek to invalidate all three patents asserted by Bard in the litigation. Our petitions were granted and 40 of Bard's 41 patentclaims were rejected and, following further proceedings, the Patent Office issued a Final Rejection of all 40 claims subject to reexamination. Thereafter, Bardfiled appeals to the PTO Board of Appeals and Interferences for all three reexams. The parties completed briefing on the appeals and oral argument was heldon June 18, 2015. The Patent Office issued decisions in the three appeals. In one (issued on March 11, 2016 for US Patent No. 7,785,302), the rejections of sixof the ten claims under reexamination were affirmed, but were reversed on four of the ten claims. In the second (issued on March 24, 2016 for U.S. Patent No.7,959,615), the rejections of eight of the ten claims under reexamination were affirmed but the rejections of the other two of the ten claims were reversed. Inthe third (issued on March 29 for U.S. Patent No. 7,947.022) the rejections of all twenty claims under reexamination were affirmed. Bard has since filedRequests for Rehearing in all three reexamination appeals and the Company filed Requests for Rehearing in two of the reexamination appeals (the ‘302 and‘615 patent reexaminations). Each party has filed comments in Opposition to the other party’s Rehearing Requests,. The PTO has since issued decisionsdenying all Rehearing Requests - - on February 1, 2017 for the ‘302; on February 17, 2017 for the ‘022; and on February 21, 2017 for the ‘615. In the ‘302and ‘022, the PTO modified its characterization of one prior art reference. Bard has since filed a Notice of Appeal to the Federal Circuit Court of Appeals inall three reexams and we filed Cross-Appeals in the ‘302 and the ‘615 reexams. The parties are in the process of preparing and filing the various appellatebriefs, starting with Bard’s Opening Brief which is currently due on July 31, 2017 and ending with our Reply Brief which is currently due on November 6,2017. The Utah Action has been stayed pending final resolution of the PTO process. We believe87these claims are without merit and intend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it isnot yet possible to determine if a potential loss is probable nor reasonably estimable.On March 10, 2015, C.R. Bard, Inc. and Bard Peripheral Vascular, Inc. (“Bard”) filed suit in the United States District Court for the District of Delawareclaiming certain of our implantable port products infringe on three U.S. patents held by Bard (the “Delaware Action). Bard is seeking unspecified damagesand other relief. The patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1, 2015, we filed two motions inresponse to Bard’s Complaint - one sought transfer to the District of Utah where the Utah Action is currently pending, and the other sought dismissal of theentire complaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statuteand in light of recent authority from the U. S. Supreme Court. On January 12, 2016, the court issued a decision denying both motions. We have since servedan Answer and Counterclaim to which Bard has served a Reply. On March 10, 2016, the Court held a case management conference, and, on March 14, 2016,the court entered a Scheduling Order which set, inter alia, a Markman hearing for March 10, 2017, a summary judgment hearing for December 8, 2017 andtrial for March 12, 2018. The parties have served various discovery requests on each other, and have been producing documents to each other; on May 27,2016 Bard served its Infringement Contentions which identified all the port products accused of infringement; and, on June 24, 2016, we served InvalidityContentions which detail various grounds for invalidating the three asserted patents. The parties completed briefing on the claim construction issues and theMarkman hearing was held on March 10, 2017 and the Court issued its Claim Construction Order on May 19, 2017. The Court has since amended theScheduling Order to provide for the completion of Expert Discovery on October 30, 2017; briefing on Case-Dispositive Motions between November 17,2017 and January 24, 2018 with oral argument set for February 22, 2018 and trial to commence May 29, 2018. We believe these claims are without merit andintend to defend them vigorously. We have not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if apotential loss is probable nor reasonably estimable.AngioDynamics, Inc. v. C.R. Bard, Inc.On May 30, 2017, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc. v.C.R. Bard, Inc. and Bard Access Systems, Inc. (“Bard”). In this action, we allege that Bard has illegally tied the sales of its tip location systems to the sales ofits PICCs. We allege that this practice violates the federal antitrust laws and has had, and continues to have, an anti-competitive effect in the market forPICCs. We seek both monetary damages and injunctive relief. The Court has set an initial case management conference for August 29, 2017.Governmental InvestigationsIn June 2014 we received a subpoena from the U.S. Department of Justice (the “DOJ”) requesting documents in relation to a criminal and civilinvestigation the DOJ is conducting regarding BTG International, Inc.’s LC Bead® product beginning in 2003. RITA Medical Systems and AngioDynamics,Inc., after its acquisition of RITA, was the exclusive distributor of LC Beads in the United States from 2006 through December 31, 2011. We are cooperatingfully with this investigation.In April 2015 we received a subpoena from the DOJ requesting documents in relation to a criminal and civil investigation the DOJ is conductingregarding purported promotion of certain of AngioDynamics’ VenaCure EVLT products for un-cleared indications. We are cooperating fully with thisinvestigation.As of May 31, 2017 the Company accrued $12.5 million for these matters and in August 2017, the Company agreed in principle with the government toresolve these matters for approximately $12.5 million.16.
