(together with its subsidiaries, "AngioDynamics," the "Company," "we," "our" or "us") designs, manufactures and sells a wide range ofmedical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for usein oncology and surgical settings. Our devices are generally used in minimally invasive, image-guided procedures.HistoryAngioDynamics was founded in 1988 and we completed our initial public offering in 2004, raising net proceeds of approximately $21.7 million at anoffering price of $11.00 per share. In 2006 we completed a follow-on offering, raising net proceeds of approximately $61.9 million at a public offering price of$24.07 per share.ProductsOur product offerings fall within three product groupings: Peripheral Vascular, Vascular Access and Oncology/Surgery. All products discussed below havebeen cleared for sale in the United States by the FDA. International regulatory clearances vary by product and jurisdiction.Peripheral Vascular ProductsOur Peripheral Vascular products include Fluid Management, Venous, Thrombus Management, as well as other core products.Fluid Management ProductsOur Fluid Management product offering includes the NAMIC ® Fluid Management portfolio. Since 1969, the NAMIC product line has been the 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 and interventionalaccessories. These devices are utilized together and allow clinicians to aspirate or inject contrast, saline, remove waste and monitor invasive blood pressuresthroughout the procedure.Venous ProductsOur venous products focus on the treatment of varicose veins and consist of our VenaCure EVLT ® laser system and Sotradecol ® . An estimated one-half ofall Americans older than age 50 suffer from varicose veins, making the market for the treatment large and growing.Our VenaCure EVLT laser system products are used in endovascular laser procedures to treat superficial venous disease (varicose veins). Superficial venousdisease is a malfunction of one or more valves in the leg veins whereby blood refluxes or does not return to the heart. Venous laser treatment is an outpatientprocedure that generally allows the patient to quickly return to normal activities with minimal post-operative pain.With our VenaCure EVLT laser system, laser energy is used to stop the reflux by ablating, or collapsing and destroying, the affected vein. The bodysubsequently re-routes the blood to other healthy veins. Our products are sold as a system that includes diode laser hardware with our family of disposable laserfiber components, training and marketing materials. The disposable components in the system include a laser fiber system featuring our NeverTouch ® gold-tiptechnology, an access sheath, access wires and needles. The procedure kits come in a variety of lengths and configurations to accommodate varied patientanatomies. Our VenaCure EVLT 1470 nanometer wavelength laser allows customers to more efficiently heat the vein wall using lower power settings therebyreducing the risk of collateral damage.Sotradecol ® (sodium tetradecyl sulfate injection) is an FDA approved sclerosing drug that we distribute through a global agreement with the manufacturer.Sotradecol ® has been shown to be an effective non-surgical treatment of small, uncomplicated varicose veins of the lower extremities that show simple dilationwith competent valves.2Thrombus ManagementOur Thrombus Management product offerings include our AngioVac and thrombolytic products .AngioVacIn fiscal 2013, we released our AngioVac venous drainage system which includes a Venous Drainage Cannula and Cardiopulmonary Bypass Circuit. TheAngioVac devices are for use with other manufacturer’s off-the-shelf pump, filter, and reinfusion cannula, to facilitate venous drainage as part of an extracorporealbypass procedure. The cannula is indicated for use as a venous drainage cannula and for removal of fresh, soft thrombi or emboli during extracorporeal bypass. Thecardiopulmonary bypass circuit is indicated for use in procedures requiring extracorporeal circulatory support for periods of up to six hours.The AngioVac venous drainage cannula is a 22F coil-reinforced cannula designed with a balloon actuated, expandable funnel shaped distal tip. Theproprietary 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.Thrombolytic ProductsThrombolytic catheters are used to deliver thrombolytic agents, which are drugs that dissolve blood clots in hemodialysis access grafts, arteries, veins andsurgical bypass grafts.Core ProductsOur other core peripheral vascular products include Angiographic products and accessories, drainage, micro access and other products.Angiographic Products and AccessoriesAngiographic products and accessories are used during peripheral vascular interventional procedures. These products permit interventional physicians toreach targeted locations within the vascular system to deliver contrast media for visualization purposes and therapeutic agents and devices, such as percutaneoustransluminal angioplasty (PTA) balloons. Angiographic products consist primarily of angiographic catheters, but also include entry needles and guidewiresspecifically designed for peripheral interventions and fluid management products. We manufacture angiographic catheters and guidewires that are available inmore than 500 tip configurations and lengths.Drainage ProductsDrainage products percutaneously drain abscesses and other fluid pockets. An abscess is a tender inflamed mass that typically must be drained by aphysician.Our line of drainage products, The Total Abscession ® Family of Drainage Catheters, consists of our Total Abscession General, Biliary, and Nephrostomydrainage catheters. These products feature our proprietary soft shaft with Blue Silk ™ finish for a more comfortable patient fit. The kink-resistant shaft recoversrapidly, even if severely bent, knotted, or twisted. This is particularly beneficial when patients roll over and risk a potential kinking of the catheter duringsleep. The thermal molded tip allows for less buckling and kinking upon insertion. Also important is that the shaft diameter equals the inner diameter of thecatheter hub to maximize flow. Our Total Abscession drainage catheters feature a tamper-resistant locking mechanism called the Vault ® which securely fixes thepigtail and prevents tampering or accidental removal. This locking mechanism helps to prevent the drain from becoming unlocked during routine use, thusreducing a physician’s time by avoiding a possible “redo” case, and increasing patient satisfaction by not having to repeat the procedure. The Total Abscessioncatheter permits aspiration in the locked or unlocked position thus allowing more accurate placement and greater versatility for draining complex situations.3Micro 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 build a custom set from the wide selection of configurations available, including four wires in two different lengths, sevenneedle options and three sheath dilator options.Vascular AccessImage-guided vascular access, or IGVA, involves the use of advanced imaging equipment to guide the placement of catheters that deliver primarily short-term drug therapies, such as chemotherapeutic agents and antibiotics, into the central venous system. Delivery to the circulatory system allows drugs to mix with alarge volume of blood as compared to intravenous drug delivery into a superficial vessel. IGVA procedures include the placement of PICC lines, implantable portsand central venous catheters, or CVCs.BioFlo ® Our BioFlo products incorporate Endexo Technology into the manufacturing and design of our Vascular Access products. Endexo is a fluorine based additivethat creates a non-eluting (permanent), non-heparin based catheter material that is designed to reduce thrombus accumulation and platelet adhesion to all surfacesof the catheter. BioFlo’s long-term durability and efficacy is intended to provide clinicians a high degree of safety and confidence in providing better patient careand improved patient outcomes.PICC ProductsA peripherally inserted central catheter, or PICC, is a long thin catheter that is inserted into a peripheral vein, typically in the upper arm, and advanced untilthe 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 of time andprovide 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 and designof the catheter. Advanced features such as large lumen diameters allow the BioFlo ® PICC to deliver the power injection flow rates required forcontrast-enhanced computed tomography (CT) scans compatible with up to 325 psi CT injections.•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.Port ProductsPorts are implantable devices utilized for the central venous administration of a variety of medical therapies and for blood sampling and diagnostic purposes.Central venous access facilitates a more systemic delivery of treatment agents, while mitigating certain harsh side effects of certain treatment protocols andeliminating the need for repeated access to peripheral veins. Depending upon needle gauge size and the port size, a port can be utilized for up to approximately2,000 accesses once implanted in the body. Our ports are used primarily in systemic or regional short and long-term cancer treatment protocols that requirefrequent infusions of highly concentrated or toxic medications (such as chemotherapy agents, antibiotics or analgesics) and frequent blood samplings.Our port products and accessories include:•BioFlo ® Port : Our BioFlo line is the only port available that incorporates Endexo Technology into the manufacturing and design of the catheter.Advanced features include multiple profile and catheter options, a large septum area for ease of access and the ability to administer contrast through aCT (Computed Tomography) injection for purposes 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 Computed Tomography (CT) scan. The ability to access a port forpower-injected contrast studies4eliminates the need for additional needle sticks in the patient’s arm and wrist veins. Once implanted, repeated access to the bloodstream can beaccomplished 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 wide variety of dialysis catheters, including:•BioFlo ® : Our BioFlo line is the only dialysis catheter available that incorporates Endexo Technology into the manufacturing and design of thecatheter. Advanced features include large inner diameter lumens designed for long term patency, a proprietary guidewire lumen to facilitate catheterexchanges and Curved Tip Technology that allows the catheter to self-center in the SVC (Superior Vena Cava).•DuraMax ® . The DuraMax catheter is a stepped-tip catheter designed to improve ease of use, dialysis efficiency and overall patient outcomes.Oncology / Surgery ProductsOur Oncology/Surgery product offerings include our Microwave Ablation products, our Radiofrequency Ablation (RFA) and our NanoKnife product lines.Microwave Ablation ProductsThe Acculis Microwave Tissue Ablation (MTA) System complements the full range of ablative technologies we offer. When configured for use with theAccu2i pMTA Applicators, it includes the Sulis VpMTA Generator, optional MTA Temperature Probes, Acculis Local Control Station (LCS) and Accu2i pMTAApplicators. Designed for physicians trained in image-guided ablation procedures, intraoperative ultrasound and/or CT guided needle placement, the system is usedfor thermal coagulation of soft tissue. By utilizing 2.45 GHz of microwave energy, the Acculis MTA System can complete ablations up to 5 cm in six minutes witha single applicator. Applicators are available in 14 cm, 19 cm and 29 cm lengths, offering flexibility in selecting the appropriate length for the procedure.Additionally, an antenna transmits energy directly to the targeted tissue, eliminating the need for electrosurgical grounding pads, while the single, simple to placeinsertion applicator eliminates the need to deploy an active array.Radiofrequency Ablation ProductsRadiofrequency Ablation (RFA) products use radiofrequency energy to provide a minimally invasive approach to ablating solid cancerous or benign tumors.Our system delivers radiofrequency energy to raise the 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, computed tomography or magneticresonance imaging guidance. Once the device is inserted, pushing on the handle of the device causes a group of curved wires to be deployed from the tip of theelectrode. When the power is turned on, these wires deliver radiofrequency energy throughout the tumor. In addition, temperature sensors on the tips of the wiresmeasure tissue temperature throughout the procedure.During the procedure, our system automatically adjusts the amount of energy delivered in order to maintain the temperature necessary to ablate the targetedtissue. For a typical 5cm ablation using our StarBurst ® Xli-enhanced disposable5device, the ablation process takes approximately ten minutes. When the ablation is complete, pulling back on the handle of the device causes the curved wire arrayto be retracted into the device so it can be removed from the body.The RFA system consists of a radiofrequency generator and a family of disposable devices. We also market the Habib ® 4X ® resection device under adistribution agreement with EMcision Limited. In addition to the intra-operative (open surgery) device Habib 4X, AngioDynamics markets a minimally-invasiveversion of the Habib 4X device, a Laparoscopic 4X unit, which is used in minimally invasive laparoscopic surgery (MILS) procedures in surgical specialties suchas: Hepato-Biliary, GI, Surgical Oncology, Transplant Surgery and Urology (Partial Nephrectomy Resections). It is clinically indicated to assist in coagulation oftissue during intraoperative and laparoscopic procedures.NanoKnife ® Ablation System ProductsThe NanoKnife ® Ablation System is for the surgical ablation of soft tissue. The NanoKnife Ablation System utilizes low energy direct current electricalpulses to permanently open pores in target cell membranes. These permanent pores or nano-scale defects in the cell membranes result in cell death. The treatedtissue is then removed by the body’s natural processes in a matter of weeks, mimicking natural cell death. Unlike other ablation technologies, NanoKnife AblationSystem does not 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 electrode probes. Upto six (6) electrode probes can be placed into or around the targeted soft tissue. Once the probes are in place, the user enters the appropriate parameters for voltage,number of pulses, interval between pulses, and the pulse length into the generator user interface. The generator then delivers a series of short electric pulsesbetween each electrode probe. The energy delivery is hyperechoic and can be monitored under real-time ultrasound.Research & DevelopmentOur growth depends in large part on the continuous introduction of new and innovative products, together with ongoing enhancements to our existingproducts, through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to makeinvestments in, research and development.Our R&D development teams work closely with our sales force to incorporate customer feedback into our development and design process. We believe thatwe have a reputation among interventional physicians as a strong partner for product development because of our tradition of close physician collaboration,dedicated market focus, responsiveness and execution capabilities for product development and commercialization.CompetitionWe encounter significant competition across our product lines and in each market in which our products are sold. These markets are characterized by rapidchange resulting from technological advances and scientific discoveries. We face competitors ranging from large manufacturers with multiple business lines tosmall 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; Vascular Solutions; Medtronic; Merit Medical; Terumo Medical Corporation; Vascular Solutions andTotal Vein Systems.Many of our competitors have substantially greater financial, technological, research and development, regulatory, marketing, sales and personnel resourcesthan we do. Competitors may also have greater experience in developing products, obtaining regulatory approvals, and manufacturing and marketing suchproducts. Additionally, competitors may obtain patent protection or regulatory approval or clearance, or achieve product commercialization before us, any of whichcould materially adversely affect us.We believe that our products compete primarily on the basis of 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,increased competition 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 across productlines and markets, develop or acquire proprietary products, attract and retain skilled development personnel, obtain patent or other protection for our products,obtain required regulatory and reimbursement6approvals, manufacture and successfully market our products either directly or through outside parties and maintain sufficient inventory to meet customer demand.Sales and MarketingWe sell our broad line of quality devices in the United States through a direct sales force and internationally through a combination of direct sales anddistributor relationships. We support our customers and sales organization with a marketing staff that includes product managers, customer service representativesand other marketing specialists.We focus our sales and marketing efforts on interventional radiologists, interventional cardiologists, vascular surgeons, urologists and interventional andsurgical oncologists. There are more than 5,000 interventional radiologists, 5,000 interventional cardiologists, 2,000 vascular surgeons, 9,000 urologists and 2,000interventional and surgical oncologists in the United States.BacklogHistorically, we ship the majority of products within 24-48 hours of receipt of the orders, and accordingly our backlog is not significant.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 maintain betterquality control, ensure compliance with applicable regulatory standards and our internal specifications, and limit outside access to our proprietary technology. Wehave custom-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, distributionwarehouses and offices. These facilities are registered with the FDA and have been certified to ISO 13485 standards, as well as the CMD/CAS Canadian MedicalDevice Regulations. ISO 13485 is a quality system standard that satisfies European Union regulatory requirements, thus allowing us to market and sell ourproducts in European Union countries. Our manufacturing facilities are subject to periodic inspections by regulatory authorities to ensure compliance withdomestic and non-U.S. regulatory requirements. See “Government Regulation” section of this report for additional information. See Item 2 "Properties" for detailson each manufacturing location. Intellectual PropertyPatents, trademarks and other proprietary rights are very important to our business. We also rely upon trade secrets, manufacturing know-how, technologicalinnovations and licensing opportunities to maintain and improve our competitive position. We regularly monitor and review third-party proprietary rights,including patents and patent applications, as available, to aid in the development of our intellectual property strategy, avoid infringement of third-party proprietaryrights, and identify licensing opportunities.Most of our products are sold under the AngioDynamics trade name or trademark. Additionally, many 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.As of May 31, 2015 , we owned or had exclusive licenses to 242 U.S. utility patents, 113 pending U.S. utility applications, and 86 foreign issued and pendingutility patents. We also own 68 U.S. registered trademarks and 51 common law trademarks. We currently have 115 registered international trademarks and 12pending international trademarks.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 that couldprevent the manufacture and sale of affected products or result in significant royalty payments in order to continue selling the products. While it is not possible topredict the outcome of patent litigation incidents7to our business, we believe the costs associated with this type of litigation could have a material adverse impact on our consolidated results of operations, financialposition, or cash flows. The medical device industry is also susceptible to significant product liability claims. These claims may be brought by individuals seekingrelief on their own behalf or purporting to represent a class. In addition, product liability claims may be asserted against us in the future based on events we are notaware of at the present time. At any given time, we are involved in a number of product liability actions. For additional information, see both Part I. Item 3 of thisreport and Note O to the consolidated financial statements in this annual report on Form 10-K.Government RegulationThe products we manufacture and market are subject to regulation by the FDA under the Federal Food, Drug, and Cosmetic Act, or FDCA, and, in someinstances, state authorities and foreign governments.United States FDA Regulation - Before a new medical device can be introduced into the market, a manufacturer generally must obtain marketing clearance orapproval from the FDA through either a 510(k) submission (a premarket notification) or a premarket approval application, or PMA.The 510(k) procedure is available only in particular circumstances. The 510(k) clearance procedure is available only if a manufacturer can establish that itsdevice 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 grandfather status based upon commercial distribution on or before May 28, 1976. After a device receives 510(k) clearance, anymodification that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearanceor could require a PMA approval. The 510(k) clearance procedure generally takes from four to 12 months from the time of submission, but may take longer. Insome cases, supporting clinical data may be required. The FDA may determine that a new or modified device is not substantially equivalent to a predicate device ormay require that additional information, including clinical data, be submitted before a determination is made, either of which could significantly delay theintroduction of new or modified device products. If a product does not satisfy the criteria of substantial equivalence, it is placed in class III and premarket approvalis required prior to the introduction of that product into the market.The PMA application procedure is more comprehensive than the 510(k) procedure and typically takes several years to complete. The PMA application mustbe supported by scientific evidence providing pre-clinical and clinical data relating to the safety and efficacy of the device and must include other informationabout the device and its components, design, manufacturing and labeling. The FDA will approve a PMA application only if a reasonable assurance that the deviceis safe and effective for its intended use can be provided. As part of the PMA application review, the FDA will inspect the manufacturer’s facilities for compliancewith its Quality System Regulation, or QSR. As part of the PMA approval the FDA may place restrictions on the device, such as requiring additional patientfollow-up for an indefinite period of time. If the FDA’s evaluation of the PMA application or the manufacturing facility is not favorable, the FDA may denyapproval of the PMA application or issue a “not approvable” letter. The FDA may also require additional clinical trials, which can delay the PMA approval processby several years. After the PMA is approved, if significant changes are made to a device, its manufacturing or labeling, a PMA supplement containing additionalinformation 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 FDA clearance and approval processes for a medical device are expensive, uncertain and lengthy. There can be no assurance that we will be able toobtain necessary regulatory clearances or approvals for any product on a timely basis or at all. Delays in receipt of or failure to receive such clearances orapprovals, the loss of previously received clearances or approvals, or the failure to comply with existing or future regulatory requirements could have a materialadverse effect on our business, financial condition and results of operations.After a product is placed on the market, the product and its manufacturer are subject to pervasive and continuing regulation by the FDA. The FDA enforcesthese requirements by inspection and market surveillance. Our suppliers also may be subject to FDA inspection. We must therefore continue to spend time, moneyand effort to maintain compliance. Among other things, we must comply with the Medical Device Reporting regulation, which requires that manufacturers reportto the FDA if their device may have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death orserious injury if it were to recur. We must also comply with the FDA’s corrections and removal reporting regulation, which requires that manufacturers report tothe FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by a device or to remedy a violation of the FDCA that maypresent a risk to health.8The labeling and promotion activities for devices are subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. The FDA activelyenforces regulations prohibiting the marketing of devices for unapproved new uses.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 subassemblies, 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 to registertheir facilities and list their products with the FDA and certain state agencies. The FDA periodically inspects manufacturing facilities and, if there are allegedviolations, the operator of a facility must correct them or satisfactorily demonstrate the absence of the violations or face regulatory action.We are subject to inspection and marketing surveillance by the FDA to determine our compliance with all regulatory requirements. Recently, the FDA hasplaced an increased emphasis on enforcement of the QSR and other postmarket regulatory requirements. Non-compliance with applicable FDA requirements canresult in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the FDA to grantmarketing approvals, withdrawal of marketing approvals, a recommendation by the FDA to disallow us to enter into government contracts, and criminalprosecutions. The FDA also has the authority to request repair, replacement or refund of the cost of any device manufactured or distributed by us.Other - We and our products are also subject to a variety of state and local laws in those jurisdictions where our products are or will be marketed, and federal,state and local laws relating to matters such as safe working conditions, manufacturing practices, environmental protection, fire hazard control and disposal ofhazardous or potentially hazardous substances. In addition, we are subject to various federal and state laws governing our relationships with the physicians andothers who purchase or make referrals for our products. For instance, federal law prohibits payments of any form that are intended to induce a referral for any itempayable under Medicare, Medicaid or any other federal healthcare program. Many states have similar laws. There can be no assurance that we will not be requiredto incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a material adverse effect uponour ability to do business.International Regulation - Internationally, all of our current products are considered medical devices under applicable regulatory regimes, and we anticipatethat this will be true for all of our future products. Sales of medical devices are subject to regulatory requirements in many countries. The regulatory review processmay vary greatly from country to country. For example, the European Union has adopted numerous directives and standards relating to medical devices regulatingtheir design, manufacture, 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 distributed incountries that are members of the European Union.In some cases, we rely on our international distributors to obtain regulatory approvals, complete product registrations, comply with clinical trial requirementsand 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 must firstcomply 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 of 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 States - The delivery of our devices is subject to regulation by the Department of Health and Human Services (HHS) and comparable state and non-U.S. agencies responsible for reimbursement and regulation of health care items and services. U.S. laws and regulations are imposed primarily in connection withthe Medicare 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.9U.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 receive remunerationof any kind for the purpose of including or rewarding referrals of items or services reimbursable by a federal health care program; (2) the False Claims Act whichprohibits the submission of false or otherwise improper claims for payment to a federally-funded health care program, including claims resulting from a violationof the Anti-kickback Statute; (3) the Stark law which prohibits physicians from referring Medicare or Medicaid patients to a provider that bills these programs forthe provision of certain designated health services if the physician (or a member of the physician’s immediate family) has a financial relationship with thatprovider; 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,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 parties outsidethe U.S. if the physician or party is a government official of another country and the arrangement violates the law of that country.International - Our success in international markets will depend largely upon the availability of reimbursement from the third-party payors through whichhealthcare providers are paid in those markets. Reimbursement and healthcare payment systems vary significantly by country. The main types of healthcarepayment systems 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 will sellour products. There can be no assurance that reimbursement approvals will be received.InsuranceOur product liability insurance coverage is limited to a maximum of $10,000,000 per product liability claim and an aggregate policy limit of $10,000,000,subject to a self-insured retention of $500,000 per occurrence and $1,250,000 in the aggregate. The policy covers, subject to policy conditions and exclusions,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 claim withrespect to uninsured or underinsured liabilities could have a material adverse effect on our business.EnvironmentalWe 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. Although we believe that wehave complied with these laws and regulations in all material respects and, to date, have not been required to take any action to correct any noncompliance, therecan be no assurance that we will not be required to incur significant costs to comply with environmental regulations in the future.EmployeesAs of May 31, 2015 , we had approximately 1,300 full time employees. None of our employees are represented by a labor union and we have neverexperienced a work stoppage.Executive Officers of the CompanyThe following table sets forth certain information with respect to our executive officers. 10Name Age PositionJoseph M.

Information on our website or connected to our website is not incorporated by reference into thisannual report on Form 10-K.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 in evaluating theCompany's business. Our financial and operating results are subject to a number of factors, many of which are not within our control. These factors include thoseset forth below. Our business, financial condition or results of operations could be materially and adversely affected by any of these risks. Additional risks notpresently known to us or that we currently deem immaterial may also adversely affect our business, financial condition or results of operations.If 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 customers andattract new customers, recruit, retain and effectively manage employees, as well as expand operations and integrate customer support and financial control systems.If integration - related expenses and capital expenditure requirements are greater than anticipated or if we are unable to manage our growth profitably, our financialresults 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 cost reductioninitiatives. While we have realized some efficiencies from these actions, we may not realize the benefits of these initiatives to the extent we anticipated. Further,such benefits may be realized later than expected, and the ongoing difficulties in implementing these measures may be greater than anticipated, which could causeus to incur additional costs or result in business disruptions. In addition, if these measures are not successful or sustainable, we may undertake additionalrealignment and cost reduction efforts, which could result in significant additional charges. Moreover, if our restructuring and realignment efforts proveineffective, our ability to achieve our other strategic goals and business plans may be adversely affected12We 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 anticipate that wewill do so for future products as well. Any delays in delivery of or shortages in those or other products and components could interrupt and delay manufacturing ofour products and result in the cancellation of orders for our products. Any or all of these suppliers could discontinue the manufacture or supply of these productsand components at any time. Due to FDA and other business considerations, we may not be able to identify and integrate alternative sources of supply in a timelyfashion or at all. Any transition to alternate suppliers may result in production delays and increased costs and may limit our ability to deliver products to ourcustomers. Furthermore, if we are unable to identify alternative sources of supply, we would have to modify our products to use substitute components, which maycause 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 Sotradecol and our Celerity tip location system.Operational, quality or regulatory issues of the manufacturers of the products we distribute could constrain or interrupt the availability of those products orservices. Any constraint, interruption in supply of finished products that we distribute could have a material adverse effect on our ability to sell products, ourfinancial condition and our results of operations.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. Theability 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 can significantlyimpact the acceptance of new technology. Implementation of healthcare reforms in the United States and in other countries may limit, reduce or eliminatereimbursement for our products and adversely affect both our pricing flexibility and the demand for our products. Even when we develop a promising new product,we may find limited demand for the product unless reimbursement approval is obtained from private and governmental third party payors.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 other means;and•the introduction of managed care systems in which healthcare providers contract to provide comprehensive healthcare for a fixed cost per person.We are unable to predict whether federal, state or local healthcare reform legislation or regulation affecting our business may be proposed or enacted in thefuture, or what effect any such legislation or regulation would have on our business. Changes in healthcare systems in the United States or elsewhere in a mannerthat significantly reduces reimbursement for procedures using our medical devices or denies coverage for these procedures, or adverse decisions relating to ourproducts by administrators of these systems in coverage or reimbursement issues, would have an adverse impact on the acceptance of our products and the priceswhich our customers are willing to pay for them.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 procedure improveshealth outcomes, including quality of life or functional ability, in a safe and cost-effective manner. Even if a device has received clearance or approval formarketing by the FDA, there is no assurance that third-party payors will cover the cost of the device and related procedures.13In 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 or reimbursement forthe procedure itself. Even if coverage is available, third-party payors may place restrictions on the circumstances where they provide coverage or may offerreimbursement 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 lists ofexclusive suppliers or approved lists of products deemed to be cost-effective. Authorization from those third-party payors is required prior to using products thatare not on these lists as a condition of reimbursement. If our products are not on the approved lists, healthcare providers must determine if the additional cost andeffort required in obtaining prior authorization, and the uncertainty of actually obtaining coverage, is justified by any perceived clinical benefits from using ourproducts.Finally, the advent of contracted fixed rates per procedure has made it difficult to receive reimbursement for disposable products, even if the use of theseproducts 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 elective surgicalprocedures. Under current prospective payment systems, such as the diagnosis related group system and the hospital out-patient prospective payment system, bothof which are used by Medicare and in many managed care systems used by private third-party payors, the cost of our products will be incorporated into the overallcost of a procedure and not be separately reimbursed. As a result, we cannot be certain that hospital administrators and physicians will purchase our products,despite the clinical benefits and opportunity for cost savings that we believe can be derived from their use. If hospitals and physicians cannot obtain adequatereimbursement for our products or the procedures in which they are used, our business, financial condition, results of operations, and cash flows could suffer amaterial 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 payment systemsare government sponsored healthcare and private insurance. Reimbursement approval must be obtained individually in each country in which our products aremarketed. Outside the United States, we generally rely on our distributors to obtain reimbursement approval in the countries in which they will sell our products.There can be no assurance that reimbursement approvals will be received. The failure to secure reimbursement approvals in international markets could materiallyimpact our financial position and results of operations.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, or IDNs,in an effort to reduce costs. GPOs and IDNs negotiate pricing arrangements with healthcare product manufacturers and distributors and offer the negotiated pricesto affiliated hospitals and other members. GPOs and IDNs typically award contracts on a category-by-category basis through a competitive bidding process. Bidsare generally solicited from multiple manufacturers with the intention of driving down pricing. Due to the highly competitive nature of the GPO and IDNcontracting processes, we may not be able to obtain market prices for our products or obtain or maintain contract positions with major GPOs and IDNs, whichcould adversely impact our profitability. Also, sales through a GPO or IDN can be significant to our business and if we are unable to retain contracts with ourcustomers, or acquire additional contracts, our financial results may be negatively impacted.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 enact cost containment efforts as means of managing thegrowth of health care utilization. Common techniques include policies on price regulation, competitive pricing, bidding and tender mechanics, coverage andpayment, comparative effectiveness of therapies, technology assessments, and managed-care arrangements. These changes are causing the marketplace to putincreased emphasis on the delivery of more cost-effective medical devices and therapies. Government programs, including Medicare and Medicaid, private healthcare insurance, and managed-care plans have attempted to control costs by limiting the amount of reimbursement they will pay for particular procedures ortreatments, tying reimbursement to outcomes, shifting to population health management, and other mechanisms designed to constrain utilization and contain costs.Simultaneously, hospitals are redefining their role in health care delivery as many assume much more risk and control of the total cost of patient care. Tosuccessfully make this transformation health systems are consolidating, purchasing or partnering with physicians, post-acute care providers, while also narrowing14networks thus allowing greater control over outcomes. Today, many systems are becoming ‘mini’ payer/provide organizations. These newly redesigned healthsystems are creating mechanisms such as value analysis and centralized purchasing functions that set pricing and in some cases limiting the number of vendors thatcan participate in the purchasing program. Hospitals are also aligning interests with physicians through employment and other arrangements, such as gainsharing,where a hospital agrees with physicians to share any realized cost savings resulting from the physicians’ collective change in practice patterns such asstandardization 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 set reimbursement levels for new or innovative devices or therapies before they will reimburse health care providerswho use the medical devices or therapies. Even though a new medical device may have been cleared for commercial distribution, we may find limited demand forthe device until coverage and sufficient reimbursement levels have been obtained from governmental and private third-party payers. In addition, some privatethird-party payers require that certain procedures or that the use of certain products be authorized in advance as a condition of reimbursement. Internationalexamples of cost containment initiatives and health care reforms advancing clinical outcomes as the key to market access are emerging in France, Germany, theNetherlands and the UK. This new criteria can severely restrict coverage, reduce reimbursement and delay access to key markets with requirements for incrementalclinical benefit and coverage with evidence development.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, changes inphysician requirements and evolving industry standards. To be successful, we must continue to develop and commercialize new products and to enhance versionsof our existing products. Our products are technologically complex and require significant research, planning, design, development and testing before they may bemarketed. This process generally takes at least 12 to 18 months from initial concept and may take up to several years. In addition, product life cycles are relativelyshort because medical device manufacturers continually develop smaller, more effective and less expensive versions of existing devices in response to physiciandemand.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; and•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 our development,introduction or marketing of new products or new versions of our existing products. As a result of such difficulties and delays, our development expenses mayincrease 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 successfully complete our researchand development, design, marketing strategy and regulatory clearance with respect to the respective products may adversely affect our business, financialcondition and results of operations.A significant aspect of our growth strategy is the continued market development of products including NanoKnife, AngioVac and BioFlo products.There can be no guarantee that we will be able to develop and manufacture additional next generation or updated products on commercially favorable terms,or at all. NanoKnife and AngioVac are developing technologies and the inability of either of them to achieve clinical acceptance, as well as our inability togenerate meaningful clinical data to convince providers of the clinical and economic benefits of our BioFlo platform, could severely limit our ability to driverevenue 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 more15specific indications, through 510(k) clearance, pre-market approval or otherwise, our ability to market our NanoKnife products will be restricted which may havean adverse effect on our business, financial condition and results of operations.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 wemay 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; Vascular Solutions; Medtronic; Merit Medical; TerumoMedical Corporation; Vascular Solutions 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 those we aredeveloping or that otherwise could render our products obsolete or noncompetitive. In addition, we may face competition from providers of other medicaltherapies, such as pharmaceutical companies, that may offer non-surgical therapies for conditions that are currently, or in the future, may be treated using ourproducts. Our products are generally sold at higher prices than those of our competitors. However, in the current environment of managed care, which ischaracterized by economically motivated buyers, consolidation among healthcare providers, increased competition and declining reimbursement rates, we areincreasingly being required to compete on the basis of price. If we are not able to compete effectively, our market share and revenues may decline.If 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 avoid infringingthe proprietary rights of others. We take precautionary steps to protect our technological advantages and intellectual property. We rely upon patent, trade secret,copyright, know-how and trademark laws, as well as license agreements and contractual provisions, to establish our intellectual property rights and protect ourproducts. However, no assurances can be made that any pending or future patent applications will result in the issuance of patents, that any current or future patentsissued to, or licensed by, us will not be challenged or circumvented by our competitors, or that our patents will not be found invalid.Patent positions of medical device companies, including our company, are uncertain and involve complex and evolving legal and factual questions. Thecoverage sought in a patent application can be denied or significantly reduced either before or after the patent is issued. Consequently, there can be no assurancethat any of our pending patent applications will result in an issued patent. There is also no assurance that any existing or future patent will provide significantprotection or commercial advantage, or whether any existing or future patent will be circumvented by a more basic patent, thus requiring us to obtain a license toproduce and sell the product. Generally, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date. In addition,publication of discoveries in the scientific or patent literature often lags behind actual discoveries. Therefore, we cannot be certain that we were the first to inventthe subject matter covered by each of our pending U.S. patent applications or that we were the first to file non-U.S. patent applications for 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 will notindependently develop or otherwise acquire substantially equivalent proprietary information or techniques, that others will not gain access to our proprietarytechnology or disclose such technology, or that we can meaningfully protect our trade secrets. We have a policy of requiring key employees and consultants toexecute confidentiality agreements upon the commencement of an employment or consulting relationship with us. Our confidentiality agreements also require ouremployees to assign to us all rights to any inventions made or conceived during their employment with us. We also16generally require our consultants to assign to us any inventions made during the course of their engagement by us. There can be no assurance, however, that theseagreements will provide meaningful protection or adequate remedies for us in the event of unauthorized use, transfer or disclosure of confidential information orinventions.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 be particularlydifficult because, in general, patent applications can be maintained in secrecy for at least 18 months after their earliest priority date. Some companies in themedical device industry have used intellectual property infringement litigation to gain a competitive advantage. If a competitor were to challenge our patents,licenses or other intellectual property rights, or assert that our products infringe its patent or other intellectual property rights, we could incur substantial litigationcosts, be forced to make expensive changes to our product design, pay royalties or other fees to license rights in order to continue manufacturing and selling ourproducts, or pay substantial damages. Third-party infringement claims, regardless of their outcome, would not only consume our financial resources but also divertour management’s time and effort. Such claims could also cause our customers or potential customers to purchase competitors’ products or defer or limit theirpurchase or use of our affected products until resolution of the claim.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. Unless anexemption applies, each medical device that we wish to market in the United States must receive either 510(k) clearance or premarket approval (PMA) from theU.S. Food and Drug Administration, or the FDA, before the product can be sold. Either process can be lengthy and expensive. The FDA’s 510(k) clearanceprocedure, also known as “premarket notification,” is the process we have used for our current products. This process usually takes from four to 12 months fromthe date the premarket notification is submitted to the FDA, but may take significantly longer. Although we have obtained 510(k) clearances for our currentproducts, our clearances may be revoked by the FDA if safety or effectiveness problems develop with the devices. The PMA process is much more costly, lengthyand uncertain. It generally 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 in other countries similarly require approval or clearance prior to our marketing or selling products in those countries. We rely on ourdistributors to obtain regulatory clearances or approvals of our products outside of the United States. If we are unable to obtain additional clearances or approvalsneeded to market existing 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 existingclearances are revoked, our revenues and profitability may decline.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 FDAenforcement actions.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 manufacturing operations; arecall of products; fines or civil penalties; seizure or detention of our products; refusing our requests for 510(k) clearance or a premarket approval, or PMA, of newor modified 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 QSR inspection, or if acorrective action plan adopted by us or one of our suppliers is not sufficient, the FDA may bring an enforcement action, and our operations could be disrupted andour manufacturing delayed. We are also subject to the FDA’s general prohibition against promoting our products for unapproved or “off-label” uses, the FDA’sadverse event reporting requirements and the FDA’s17reporting requirements for field correction or product removals. The FDA has recently placed increased emphasis on its scrutiny of compliance with the QSR andthese other postmarket requirements.We will continue to work closely with FDA to resolve any outstanding issues. Unless the items raised in the previously disclosed Warning Letters and Form483s are corrected to the FDA’s satisfaction or we come to some other arrangement with the FDA finally resolving such matters, we may be subject to additionalregulatory or legal action, including the issuance of warning letters, injunction, seizure or recall of products, imposition of fines or penalties or operatingrestrictions on our facilities. Such actions could significantly disrupt our ongoing business and operations and have a material adverse impact on our financialposition and operating results.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 issue raisedby 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 that aresimilar 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, we wouldlose our ability to market and sell our products in those countries.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 removal from themarket if there are material deficiencies or defects in design, manufacture, installation, servicing or labeling of the device, or if the governmental entity finds thatour products would cause serious adverse health consequences. A government mandated voluntary recall or field action by us could occur as a result of componentfailures, manufacturing errors or design defects, including labeling defects. Any recall of our products may harm our reputation with customers and divertmanagerial 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 regulations ofthe FDA and other applicable regulations, and the FDA determines that our promotional materials or training constitutes promotion of an unapproved use, the FDAcould request that we modify our training or promotional materials or subject us to regulatory enforcement actions, including the issuance of a warning letter,injunction, seizure, civil fine and criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they considerpromotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities,such as laws prohibiting false claims for reimbursement.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 acquisition opportunities willbe available on acceptable terms, or at all, or that we will be able to obtain necessary financing or regulatory approvals. Any acquisitions that we do undertakewould 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 strategies totake advantage of these opportunities;•inability of our management to maximize our financial and strategic position by incorporating an acquired technology or business into our existingofferings;•our inability to achieve the cost savings and operating synergies anticipated in the acquisition, which would prevent us from achieving the positiveearnings 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 and to customers of Navilyst that the acquisition will not result in adverse changes in customer servicestandards or business focus; and18•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 changes inmanagement; and•uncertainty as to the long-term success of any acquisitions we may make.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 with oneor 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 significant dilution oftheir interest in us. In addition, we could incur or assume significant amounts of indebtedness in connection with acquisitions. Further, acquisitions could alsoresult in significant goodwill and/or amortization charges for acquired businesses or technologies.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 $140 million. The terms of our credit facilities require us to comply with certain financial maintenancecovenants. In addition, the terms of our new 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 be subjectto general economic and competitive conditions and to financial, business and other factors affecting our operations, many of which are or may be beyond ourcontrol. We cannot provide assurance that our business operations will generate sufficient cash flows from operations to fund these cash requirements and debtservice obligations. If our operating results, cash flow or capital resources prove inadequate, we could face substantial liquidity problems and might be required todispose of material assets or operations to meet our debt and other obligations. If we are unable to service our debt, we could be forced to reduce or delay plannedexpansions and capital expenditures, sell assets, restructure or refinance our debt or seek additional equity capital, and we may be unable to take any of theseactions on satisfactory terms or in a timely manner. Further, any of these actions may not be sufficient to allow us to service our debt obligations or may have anadverse impact on our business. Our debt agreements limit our ability to take certain of these actions. Our failure to generate sufficient operating cash flow to payour 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 the acquisition or otherwise could materially andadversely affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, debt service requirements or other purposes, couldmake us more vulnerable to general adverse economic, regulatory and industry conditions, could limit our flexibility in planning for, or reacting to, changes andopportunities in the markets in which we compete, could place us at a competitive disadvantage compared to our competitors that have less debt or could require usto dedicate a substantial portion of our cash flow to service our debt.The presence of a significant stockholder who may sell our common stock, could cause our stock price to decline or they may affect the ability of a thirdparty to acquire control of us.The former Navilyst stockholders, including investment funds affiliated with Avista Capital Partners, beneficially own approximately 21% of ouroutstanding common stock. The sale of a substantial number of our shares by such parties or our other stockholders within a short period of time could cause ourstock price to decline, make it more difficult for us to raise funds through future offerings of our common stock or acquire other businesses using our commonstock as consideration.Certain of the former Navilyst stockholders entered into a stockholders agreement at the closing of the acquisition that permits investment funds affiliatedwith Avista Capital Partners to appoint two directors to our Board of Directors until such time as, with respect to the first director, certain of the former Navilyststockholders’ beneficial ownership in us has been reduced below 20% of the then outstanding voting shares and, with respect to the second director, certain of theformer Navilyst stockholders’ beneficial ownership in us has been reduced below 10% of the then outstanding voting shares. Although19these directors will not constitute a majority of the Board of Directors, they may exercise influence over the decisions of the board. David Burgstahler and SriramVenkataraman were appointed to our Board of Directors on May 22, 2012.Having certain of the former Navilyst stockholders as our significant stockholders of us may have the effect of making it more difficult for a third party toacquire, or of discouraging a third party from seeking to acquire, a majority of our outstanding common stock or control of our Board of Directors through a proxysolicitation. In that regard, these stockholders and their controlled affiliates are obligated pursuant to the stockholders agreement, in certain circumstances, not totransfer their shares of our common stock, in whole or in part, pursuant to any recapitalization, reclassification, consolidation, merger, share exchange or otherbusiness combination transaction involving us or pursuant to any tender, exchange or other similar offer for our common stock unless, in each case, the Board ofDirectors recommends such transaction or offer or fails to recommend that our stockholders reject such transaction or offer.For the period from the date that is one year from the date of the stockholders agreement until the first date that certain of the former Navilyst stockholdersno longer beneficially own at least ten percent (10%) of the voting securities outstanding at such time, the applicable former Navilyst stockholders agree to vote allvoting securities then owned by them either, in the sole discretion of each stockholder, (1) in accordance with the recommendation of our Board or (2) inproportion to the votes cast with respect to the voting securities not owned by the applicable former Navilyst stockholders with respect to any business or proposalon which our stockholders are entitled to vote. If at any time following one (1) year from the date of the stockholders agreement, certain of the former Navilyststockholders beneficially own less than fifteen percent (15%) of the voting securities then outstanding and there is no stockholder designee then serving on ourBoard pursuant to the stockholders agreement, the applicable former Navilyst stockholders may vote all voting securities then owned by them in their owndiscretion.Economic instability could continue to adversely affect the Company.In recent years financial markets and the economies in the United States and internationally have been experiencing a period of upheaval characterized by thebankruptcy, failure, collapse or sale of various financial institutions, severely diminished liquidity and credit availability, declines in consumer confidence, declinesin economic growth, increases in unemployment rates and uncertainty about economic stability. These conditions may continue and could worsen. As a result, theglobal economic environment may, among other things, create downward pressure on the pricing of our products, increase the sales cycle of certain products andslow the adoption of new technology, any of which could have an adverse effect on our business, financial position and results of operations.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 foreign governmentalauthorities. 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 of many payments to them. Thefederal government has recently introduced similar legislation, which may or may not preempt state laws. Recent Supreme Court case law has clarified that theFDA’s authority over medical devices preempts state tort laws, but legislation has been introduced at the federal level to allow state intervention, which could leadto increased and inconsistent regulation at the state level. We anticipate that the government will continue to scrutinize our industry closely, and that additionalregulation by governmental authorities may increase compliance costs, exposure to litigation and other adverse effects to our operations.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 20% of our net sales during our fiscal year ended May 31, 2015. We anticipate that sales frominternational operations will continue to represent a significant portion of our total sales, and we intend to continue our expansion into emerging and/or faster-growing markets outside the United States. Our sales and profitability from our international operations are subject to risks and uncertainties that can vary bycountry, and include those related to political and economic conditions, foreign currency exchange rate fluctuations, changes in tax laws, regulatory andreimbursement programs and policies, and the protection of intellectual property rights. These risks and uncertainties could have a material adverse effect on ourbusiness and/or results of operations.20Consolidation 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. As thehealthcare industry consolidates, competition to provide goods and services to industry participants will become more intense. These industry participants may tryto use their market power to negotiate price concessions or reductions for medical devices that incorporate components produced by us. If we are forced to reduceour prices because of consolidation in the healthcare industry, our revenues would decrease and our consolidated earnings, financial condition, or cash flow wouldsuffer.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 on thequality of our products, our physician-driven product development efforts, our marketing and training efforts and our presence at medical society meetings. Anyactual or perceived diminution in the quality of our products, or our failure or inability to maintain these other efforts, could damage our reputation withinterventional physicians and cause our growth to be limited and our business to be harmed.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. We compete forkey personnel with other companies, healthcare institutions, academic institutions, government entities and other organizations. We do not have writtenemployment agreements with our executive officers, other than the CEO. Our ability to maintain and expand our business may be impaired if we are unable toretain our current key personnel or hire or retain other qualified personnel in the future. In addition, our sales force is highly talented and there is high competitionin the sales industry which could have an adverse effect on our business if there is significant turnover.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 attention of ourengineering personnel to address them. There is no assurance that we will not incur warranty or repair costs, be subject to liability claims for damages related toproduct defects, or experience manufacturing, shipping or other delays or interruptions as a result of these defects in the future. Our insurance policies may notprovide sufficient protection should a claim be asserted. In addition, the occurrence of defects may result in significant customer relations problems and injury toour reputation, and may impair market acceptance of our products.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 claims against usin a number of circumstances and for a number of reasons, including if our products were misused, if a component of our product fails, if their manufacture ordesign was flawed, if they produced unsatisfactory results or if the instructions for use and operating manuals and disclosure of product related risks for ourproducts were found to be inadequate. In addition, individuals or groups seeking to represent a class may file suit against us. The outcome of litigation, particularlyclass action lawsuits, is difficult to assess or quantify. Plaintiffs in these types of lawsuits often seek recovery of very large or indeterminate amounts, including notonly actual damages, but also punitive damages. The magnitude of the potential losses relating to these lawsuits may remain unknown for substantial periods oftime.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 a self-insured retention of $500,000 per occurrence and $1,250,000 in the aggregate. We believe, based on claims made against us in the past, our existing productliability insurance coverage is reasonably adequate to protect us from any liabilities we might incur. However, there is no assurance that this coverage will besufficient to satisfy any claim made against us. In addition, we may not be able to continue to maintain adequate coverage at a reasonable cost and on reasonableterms, if at all. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us fromsecuring any coverage in the future. Additionally, if one or more product liability claims is brought against us for uninsured liabilities or is in excess of ourinsurance coverage, our financial condition and21results of operations could be negatively impacted. Further, such claims may require us to recall some of our products, which could result in significant costs to usand could divert management’s attention from our business.Modifications to our current products may require new marketing clearances or approvals or require us to cease marketing or recall the modifiedproducts until 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 its owndetermination as to whether a modification requires a new 510(k) clearance or premarket approval, but the FDA may review and disagree with any decisionreached by the manufacturer. We have modified aspects of some of our devices since receiving regulatory clearance. We believed that some of these modificationsdid not require new 510(k) clearance or premarket approval and, therefore, we did not seek new 510(k) clearances or premarket approvals. In the future, we maymake additional modifications to our products after they have received FDA clearance or approval and, in appropriate circumstances, determine that new clearanceor approval is unnecessary. Regulations in other countries in which we market or sell, or propose to market or sell, our products may also require that we makejudgments about changes to our products and whether or not those changes are such that regulatory approval or clearance should be obtained. In the United Statesand elsewhere, regulatory authorities may disagree with our past or future decisions not to seek new clearance or approval and may require us to obtain clearanceor approval for modifications to our products. If that were to occur for a previously cleared or approved product, we may be required to cease marketing or recallthe modified device until we obtain the necessary clearance or approval. Under these circumstances, we may also be subject to significant regulatory fines or otherpenalties. If any of the foregoing were to occur, our financial condition and results of operations could be negatively impacted.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 claims laws.Violations of these laws are punishable by criminal or civil sanctions, including substantial fines, imprisonment and exclusion from participation in healthcareprograms such as Medicare and Medicaid and health programs outside the United States. These laws and regulations are wide ranging and subject to changinginterpretation and application, which could restrict our sales or marketing practices. Furthermore, since many of our customers rely on reimbursement fromMedicare, Medicaid and other governmental programs to cover a substantial portion of their expenditures, our exclusion from such programs as a result of aviolation of these laws could have a material adverse effect on our business, results of operations, financial condition and cash flow.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 obtaining orretaining business. Because of the predominance of government-sponsored healthcare systems around the world, many of our customer relationships outside of theUnited States are with governmental entities and are therefore subject to such anti-bribery laws. Our sales to customers and distributors outside of the United Stateshave been increasing and we expect them to continue to increase in the future. If our employees or agents violate the provisions of the FCPA or other anti-briberylaws, we may incur fines or penalties, we may be unable to market our products in other countries or we may experience other adverse consequences which couldhave a material adverse effect on our operating results or financial condition.Any disaster at our manufacturing facilities could disrupt our ability to manufacture our products for a substantial amount of time, which could causeour revenues to decrease.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 to the other, replace, or repair these facilities and our manufacturingequipment if they were significantly affected by a disaster. Additionally, we might be forced to rely on third-party manufacturers or to delay production of ourproducts. Insurance for damage to our properties and the disruption of our business from disasters may not be sufficient to cover all of our potential losses and maynot continue to be available to us on acceptable terms, or at all. In addition, if one of our principal suppliers were to experience a similar disaster, uninsured loss orunder-insured loss, we might not be able to obtain adequate alternative sources of supplies or products or could face significant delays and incur substantialexpense in doing so. Any significant22uninsured loss, prolonged or repeated disruption, or inability to operate experienced by us or any of our principal suppliers could cause significant harm to ourbusiness, financial condition and results of operations.Our future operating results are difficult to predict and may vary significantly from quarter to quarter, which may adversely affect the price of ourcommon stock.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 results or operating results. The price of our common stock will likely fall in the event that ouroperating results 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 distributors internationally;•actions relating to ongoing FDA compliance;•the effect of intellectual property disputes;•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 of whichare 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;•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 substantial priceand volume volatility that is often seemingly unrelated to the operating performance of particular companies. These broad market fluctuations may cause thetrading price of our common stock to decline. In the past, securities class action litigation has often been brought against a company after a period of volatility inthe market price of its common stock. We may become involved in this type of litigation in the future. Any securities litigation claims brought against us couldresult in substantial expense and the diversion of management’s attention from our business.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 to resist achange in control. These provisions may discourage, delay or prevent a change in the ownership of our company or a change in our management. In addition, theseprovisions could limit the price that investors would be willing to pay in the future for shares of our common stock. Such provisions include:23•our board of directors is authorized, without prior stockholder approval, to create and issue “blank check” preferred stock, with rights senior to thoseof 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 for aperson 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 proposals thatcan be acted upon at stockholder meetings;•stockholder action by written consent is prohibited; and•stockholders are not permitted to accumulate their votes 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 of directors,including delaying or impeding a merger, tender offer or proxy contest involving our company. Any delay or prevention of a change of control transaction orchanges in our board of directors could cause the market price of our common stock to decline.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 determine thatthose assets are impaired.Most of our intangible and fixed assets have determinable useful lives and are amortized or depreciated over their useful lives on either a straight-line basisor over the expected period of benefit or as revenues are earned from the sales of the related products. The underlying assumptions regarding the estimated usefullives of these intangible assets are reviewed annually and more often if an event or circumstance occurs making it likely that the carrying value of the assets maynot be recoverable and are adjusted through accelerated amortization if necessary. Whenever events or changes in circumstances indicate that the carrying value ofthe assets is not recoverable we test intangible assets for impairment based on estimates of future cash flows. If an intangible asset is considered to be impaired, theamount of the impairment will equal the excess of the carrying value over the fair value of the asset. During the third quarter of fiscal 2015, we recorded animpairment charge of $6.4 million associated with trademarks.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 current businessstrategy in light of present industry and economic conditions, as well as future expectations. The annual goodwill impairment review performed in December 2014indicated 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.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 require additionaldebt or equity financing. In addition, we may require financing to fund any significant acquisitions we may seek to make. Needed financing may not be availableor, if available, may not be available on terms satisfactory to us and may result in significant stockholder dilution. Covenants in our existing financing agreementsmay also restrict our ability to obtain additional debt financing. If we fail to obtain sufficient additional capital in the future, we could be forced to curtail ourgrowth strategy by reducing or delaying capital expenditures and acquisitions, selling assets, restructuring our operations or refinancing our indebtedness.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 large multi-national companies, the size and complexity of our information technology systems24makes them vulnerable to a cyber-attack, malicious intrusion, breakdown, destruction, loss of data privacy, or other significant disruption. Our information systemsrequire an ongoing commitment of significant resources to maintain, protect, and enhance existing systems and develop new systems to keep pace with continuingchanges in information processing technology, evolving systems and regulatory standards, the increasing need to protect patient and customer information, andchanging customer patterns. In addition, third parties may attempt to hack into our products to obtain data relating to patients with our products or our proprietaryinformation. Any failure by us to maintain or protect our information technology systems and data integrity, including from cyber-attacks, intrusions or otherbreaches, could result in the unauthorized access to patient data and personally identifiable information, theft of intellectual property or other misappropriation ofassets, or otherwise compromise our confidential or proprietary information and disrupt our operations. Any of these events, in turn, may cause us to lose existingcustomers, have difficulty preventing, detecting, and controlling fraud, have disputes with customers, physicians, and other health care professionals, be subject tolegal claims and liability, have regulatory sanctions or penalties imposed, have increases in operating expenses, incur expenses or lose revenues as a result of a dataprivacy breach or theft of intellectual property, or suffer other adverse consequences, any of which could have a material adverse effect on our business, financialcondition or results of operations.The Company has substantial deferred tax assets that could become impaired and result in a charge to earnings.Our Federal net operating loss carryforwards as of May 31, 2015 after considering IRC Section 382 limitations are $147.6 million. The expiration of theFederal net operating loss carryforwards are as follows: $30.7 million between 2017 and 2026 and $116.9 million between 2027 and 2033.Our state net operating loss carryforwards as of May 31, 2015 after considering remaining IRC Section 382 limitations are $29.4 million which expire invarious years from 2015 to 2033.If future results are less than projected in the U.S. and if tax planning alternatives do not offset those effects, a valuation allowance may be required to reducethe deferred tax asset, which could have a material impact on our results of operations in the period in which it is recorded. While the net deferred tax asset at May31, 2015 is $19.3 million, if the Company were required to record a valuation allowance it could be $15.3 million greater than this amount due to deferred taxliabilities related to intangibles that have an indefinite reversal period.Item 1B.Unresolved Staff Comments.None.

Item 3.Legal Proceedings.AngioDynamics v. biolitecOn January 2, 2008, we commenced an action in the United States District Court for the Northern District of New York entitled AngioDynamics, Inc.v. biolitec, Inc. In this action, we sought judgment against biolitec for defense and indemnification in two lawsuits which we previously settled. Our claims ariseout of a Supply and Distribution Agreement (“SDA”) entered into with biolitec on April 1, 2002. On September 27, 2011, the U.S. District Court granted keyportions of25our motion for summary judgment in our legal case against biolitec. The Court also dismissed biolitec’s counterclaims against us. The court denied one portion ofour summary judgment motion, which sought to recover additional costs from biolitec, leaving this for adjudication at trial. On November 8, 2012, the Courtgranted partial judgment to us in the amount of $23.2 million. Biolitec appealed this judgment. On August 23, 2013, the U.S. Court of Appeals for the SecondCircuit dismissed biolitec’s appeal.In October 2009, we commenced an action in the United States District Court for the District of Massachusetts entitled AngioDynamics, Inc. v.biolitec AG and Wolfgang Neuberger. The Complaint in this action was amended in March 2010. This action seeks to recover against biolitec, Inc.’s parent entitiesand CEO for tortiously interfering with biolitec, Inc.’s contractual obligation to defend and indemnify us, and also seeks to pierce the corporate veil of biolitec, Inc.and to invalidate certain alleged fraudulent transfers in order to hold biolitec, Inc.’s parent entities jointly and severally liable for the alleged breach of the SDA. OnSeptember 13, 2012, the Massachusetts Court granted our request for a preliminary injunction prohibiting the downstream merger of biolitec AG with its Austriansubsidiary. On April 1, 2013, the U.S. Court of Appeals for the First Circuit affirmed the preliminary injunction. On January 14, 2014, the District Court enteredjudgment in our favor as to liability. On March 18, 2014, the District Court entered judgment in our favor against Biolitec AG, Biomed Technology Holdings, Ltd.,and Wolfgang Neuberger, jointly and severally, in the amount of $74.9 million. The defendants have appealed this judgment.August 29, 2013, we became co-plaintiffs in an adversary proceeding in the United States Bankruptcy Court for the District of New Jersey entitledCyganowski, Trustee, et al. v. Biolitec U.S., Inc., et al. In this action, we assert claims of conversion, unjust enrichment, tortious interference, and unfaircompetition against various biolitec entities for alleged violation of Bankruptcy Court settlement and sale orders under which we acquired certain assets ofBiolitec, Inc. On September 3, 2013, we, along with our co-plaintiff, obtained a temporary restraining order against the defendants in this action. On January 22,2015, the Bankruptcy Court entered a permanent injunction on our behalf for an additional two years.C.R. Bard, Inc. v. AngioDynamics, Inc.On January 11, 2012, C.R. Bard, Inc. filed a suit in the United States District Court of Utah claiming certain of the Company’s implantable portproducts infringe on three U.S. patents held by Bard (the “Utah Action”). Bard is seeking unspecified damages and other relief. The Court denied Bard’s motionfor 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, the Company filed petitions for reexamination in the US Patentand Trademark Office ("PTO") which seek to invalidate all three patents asserted in the litigation. The Company’s petitions have been granted and 40 of 41 patentclaims have been and remain rejected. The Patent Office has issued a Final Rejection of all the claims subject to reexamination and Bard has filed appeals. Theparties have completed briefing on the appeals and oral argument was held on June 18, 2015. The parties are awaiting decision by the Board of Appeals andInterferences. The case has been stayed pending final resolution of the PTO process. The Company believes these claims are without merit and intends to defendthem vigorously. The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss isprobable nor reasonably estimable.On March 10, 2015, C.R. Bard, Inc. and Bard Peripheral Vascular, Inc. filed suit in the United States District Court for the District of Delawareclaiming certain of the Company’s implantable port products infringe three Bard patents (the “Delaware Action). Bard is seeking unspecified damages and otherrelief; and the patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1,2015, the Company filed two motions inresponse to Bard’s Complaint - - one seeks transfer to the District of Utah where the Utah Action is currently pending, and the other seeks dismissal of the entirecomplaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statute and in lightof recent authority from the U. S. Supreme Court. Briefing is complete on both motions (except Bard has requested permission to file a Sur-Reply on the dismissalmotion) and the parties are awaiting decision by the Delaware Court. The Company believes these claims are without merit and intends to defend them vigorously.The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable norreasonably estimable.

Our devices are generally used in minimally invasive, image-guidedprocedures. Most of our products are intended to be used once and then discarded, or they may be temporarily implanted for short- or long-term use.Our sales and profitability growth depends, in part, on the introduction of new and innovative products, together with ongoing enhancements to our existingproducts. Expansions to our product offerings are created through internal product development, technology licensing and strategic alliances. In recent years wehave acquired or developed, and launched several new products, including the AngioVac cannula and circuit, the BioFlo family of products, and the Acculismicrowave system,30which are all expected to be growth drivers of our business. We recognize the importance of, and intend to continue to make investments in, research anddevelopment activities and business development opportunities.We sell our products in the United States through a direct sales force and outside the U.S. through a combination of direct sales and distributor relationships.We expect our international business to grow in both sales and profit through geographic expansion, market penetration, and increasing our direct presence.Our ability to further increase our profitability will depend in part on improving gross profit and operating margins. A portion of improved gross margin weexpect to deliver through the acquisition, development and sale of innovative products, such as those mentioned above. Additionally, we have an active acompany-wide operational excellence program designed to create manufacturing efficiencies and drive improved business performance. Further, we anticipatebeing able to manage increases in our operating expenses at a rate slower than our sales growth to provide further operating margin expansion.Recent DevelopmentsOperational Excellence Program - On December 5, 2013, we announced a company-wide operational excellence program designed to save between $15 and$18 million during the course of the next three years and expected to create greater efficiencies and drive business performance improvements. (See Note Q ofNotes to Consolidated Financial Statements for more information related to the restructuring.)Morpheus PICC recall and product line discontinuance - during the quarter ended February 28, 2015 we made a decision to voluntarily recall our MorpheusPICC product line and concurrently discontinue the product. The recall decision was made following an internal evaluation commenced as a result ofcommunications from two international regulatory bodies which noted product complaints. Based on the evaluation performed and the lack of clear root cause, wedetermined the best course of action was to recall the product. Further, consistent with our strategy to transition toward our transformational BioFlo productofferings, we decided to discontinue the Morpheus line. The result was $6.1 million in charges during the year, including $4.8 million of inventory write-offsincluded in “Cost of sales”, as well as $1.0 million of costs associated with product returns, storage costs and other expenses which are included in “Acquisition,Restructuring and Other Items, net”.Automated Power Injector - over the last several years we have invested in the development of a new technology which was intended to create atransformational shift in our fluid management product line. As a result of recent concerns related to an extended and difficult path to regulatory approval for thedifferentiating technology, we evaluated the long-term opportunity, as well as the expected risk and costs associated with bringing this technology to market. Basedon that evaluation, in the quarter ended February 28, 2015 we made a decision to shift away from this technology toward other strategies and opportunities withinthe fluid management market. As a result we no longer expect cash flows to be generated by certain fixed assets and recorded a full impairment charge of $8.2million. In addition, the sales projected on this product were a significant portion of the long-term sales projections under the NAMIC brand. The NAMICtrademark was acquired in the Navilyst Medical acquisition and was accounted for as an indefinite lived intangible asset with a value of $28.6 million at that time.Primarily as a result of the reduction in expected NAMIC product sales driven by the discontinuance of this project, we recorded an impairment charge of $6.4million.EmboMedics, Inc. - on March 2, 2015, the Company filed an 8-K stating that it executed a non-binding letter of intent to enter into a strategic relationshipwith privately-held EmboMedics Inc., which develops injectable and resorbable embolic microspheres. On April 9, 2015 the Company entered into a License,Distribution, Manufacturing and Purchase Option Agreement with EmboMedics Inc, subject to certain approvals by EmboMedics shareholders.Under the terms of the agreement, which has not been finalized, AngioDynamics receives an exclusive worldwide license to market and sell, upon regulatoryclearances, EmboMedics’ microsphere technology. AngioDynamics will also control manufacturing of the products. AngioDynamics will make an initial $2.0million equity investment in EmboMedics through the purchase of preferred stock. The Company may make an additional $9.0 million in equity, as well asmilestone driven investments, and can execute an exclusive option to acquire EmboMedics, based on the achievement of certain milestones.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 company believes thatevaluating growth in net sales on a constant currency basis provides an additional and meaningful assessment of net sales to both management and the company’sinvestors. Constant currency growth rates are calculated by translating the prior year’s local currency sales by the current period’s exchange rate.31Constant currency growth rates are not indicative of changes in corresponding cash flows. The limitation of these non-GAAP measures is that they do not reflectresults on a standardized reporting basis. Non-GAAP measures are intended to supplement the applicable GAAP disclosures and should not be viewed asreplacements of GAAP results.Critical Accounting Policies and Use of EstimatesOur significant accounting policies are summarized in Note A to Notes to Consolidated Financial Statements included elsewhere in this annual report onForm 10-K. While all these significant accounting policies affect the reporting of our financial condition and results of operations, we view certain of these policiesas critical. Policies determined to be critical are those policies that have the most significant impact on our financial statements and require us to use a greaterdegree of judgment and/or estimates. Actual results may differ from those estimates. The accounting policies identified as critical are as follows:Revenue RecognitionWe recognize revenue in accordance with generally accepted accounting principles as outlined in the SEC’s authoritative guidance on revenue recognitionwhich requires that four criteria be met before revenue can be recognized: (i) persuasive evidence that an arrangement exists; (ii) the price is fixed or determinable;(iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. Decisions relative to criterion (iii) regardingcollectability are based upon our judgments, as discussed under “Accounts Receivable” below, and should conditions change in the future and cause us todetermine this criterion is not met; our results of operations may be affected. We recognize revenue, net of sales taxes assessed by any governmental authority, asproducts are shipped, based on F.O.B. shipping point terms when title and risk of loss passes to customers. We negotiate shipping 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 us and customers may be subject to a 20%restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least 12 months remaining prior to its expiration date.Charges for discounts, returns, rebates and other allowances are recognized as a deduction from revenue on an accrual basis in the period in which the revenue isrecorded. The accrual for product returns, discounts and other allowances is based on the company’s history. Sales rebates are accrued by the company in theperiod in which the sale is recorded.Income TaxesIn preparing our financial statements, we calculate income tax expense for each jurisdiction in which we operate. This involves estimating actual currenttaxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets andliabilities. We periodically evaluate deferred tax assets, capital loss carryforwards and tax credit carryforwards to determine their recoverability based primarily onour ability to generate future taxable income and capital gains. Where their recovery is not likely, we estimate a valuation allowance and record a correspondingadditional tax expense in our statement of operationsWe 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 2011 through 2015 remain open to examination by the various tax authorities. New York Stateis currently auditing AngioDynamic’s franchise tax filings for 2011 through 2014, and we do not anticipate any material adjustments will result. We analyzedfiling 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 these jurisdictions and believethat our income tax filing positions and deductions will be sustained on audit and we do not anticipate any adjustments will result in a material adverse effect onour financial condition, results of operations or cash flows.We do not anticipate that the amount of unrecognized tax benefits will significantly change in the next twelve months.AcquisitionsIn a business combination, the acquisition method of accounting requires that the identifiable assets acquired and liabilities assumed be measured at their fairvalue, with goodwill being the excess value of consideration paid over the fair value of the net identifiable assets acquired. IPR&D is capitalized and recorded asan indefinite-lived intangible asset at the acquisition date, contingent consideration is recorded at fair value at the acquisition date, and transaction costs areexpensed as incurred. When the company acquires net assets that are not accounted for as a business combination, no goodwill is recognized.The fair value of the liability for contingent consideration recorded on the acquisition date is based on probability weighted estimated cash flow streams,discounted back to present value using a discount rate determined in accordance with32accepted valuation methods. The liability for contingent consideration is remeasured to fair value at each reporting period with changes recorded in earnings untilthe contingency is resolved.Goodwill and Intangible AssetsIntangible assets other than goodwill, indefinite lived intangible assets and IPR&D are amortized over their estimated useful lives, which range betweenthree and twenty years, on either a straight-line basis over the expected period of benefit or as revenues are earned from the sales of the related products. Weperiodically review the estimated useful lives of our intangible assets and review such assets for impairment whenever events or changes in circumstances indicatethat the carrying value of the assets may not be recoverable. Our determination of impairment is 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.Acquired IPR&D is not amortized until completion and development of the project, at which time the IPR&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 IPR&D, calculated as the excess of the asset’s carrying value over its fair value.Our policy defines IPR&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 IPR&D requires us to make significant estimates. The amount of the purchaseprice allocated to IPR&D is determined by estimating the future cash flows of each project or technology and discounting the net cash flows back to their presentvalues. The discount rate used is determined at the time of measurement in accordance with accepted valuation methods. These methodologies includeconsideration 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 more frequently ifimpairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquiredin each business combination. Goodwill and intangible assets have been recorded at either incurred or allocated cost. Allocated costs were based on respective fairmarket 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 of thecarrying value of the assets and liabilities of that unit. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of thereporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in animpairment charge. Our determination of impairment is based on estimates of future cash flows. We consider our business to be a single operating segment entity –the development, manufacture and sale on a global basis of medical devices for vascular access, surgery, peripheral vascular disease and oncology.Results of Operations for the years ended May 31, 2015 and 2014For the fiscal year ended May 31, 2015 , we reported net loss of $3.3 million, or ($0.09) loss per diluted share, on net sales of $357.0 million compared to afiscal 2014 net income of $2.7 million, or $0.08 per diluted share, on net sales of $354.4 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, 2015 and 2014 :33 For the years ended May 31, 2015 2014 % Growth Currency Impact(Pos) Neg ConstantCurrencyGrowthNet Sales by Product Category Peripheral Vascular$192,833 $192,626 0% Vascular Access107,874 106,394 1% Oncology/Surgery52,090 49,360 6% Total Excluding Supply Agreement352,797 348,380 1% 1% 2% Supply Agreement4,177 6,045 -31% 0% -31% Total$356,974 $354,425 1% 0% 1% Net Sales by Geography United States$280,851 $280,161 0% 0% 0% International71,946 68,219 5% 4% 9% Supply Agreement4,177 6,045 -31% 0% -31% Total$356,974 $354,425 1% 0% 1%For year ended May 31, 2015, net sales increased $2.5 million to $357.0 million compared to the year ended May 31, 2014. As shown in the table above,while consolidated net sales increased by 1%, excluding the planned reduction in sales under our supply agreement and a negative impact from fluctuations incurrency exchange rates, our sales increased 2% year over year. Growth was driven by our international business, which grew 9% excluding the negative impact ofcurrency. Sales were significantly impacted by unfavorable movement in currency exchange rates, particularly the Euro, British pound and Canadian dollar, withthe remainder of the changes as compared to the prior year driven by volume.From a product line perspective, Peripheral Vascular sales increased $0.2 million primarily attributable to increased sales of AngioVac and FluidManagement products, offset by declines in our venous business and a negative impact of currency rate movements noted above. Vascular access sales increased$1.5 million as our BioFlo line of products continued to gain traction in the marketplace, offset by the voluntary recall and discontinuance of our Morpheus productline in the third fiscal quarter. Oncology/Surgery sales increased $2.7 million primarily due to the performance of NanoKnife products, particularly in theinternational markets.From a geographic perspective, U.S. sales increased $0.7 million due to growth in the Peripheral Vascular and Vascular Access products, offset by areduction in Oncology/Surgery sales. While total U.S. Oncology/Surgery declined by $0.9 million, our U.S. NanoKnife sales growth exceeded 10%. Internationalsales increased 9% on a constant-currency basis, with the largest driver being NanoKnife.Our supply agreement arrangement, which we do not include in either the U.S. or International geographic sales, declined by $1.9 million as we continue towind down that relationship.34Gross Profit, Operating expenses, and Other income (expense) For the year ended May 31, 2015 2014 % ChangeGross profit $176.9 $179.7 -1.6 %Gross profit % of sales 49.6% 50.7% Research and development $26.9 $27.5 -2.2 %% of sales 7.5% 7.8% Selling and marketing $80.6 $83.2 -3.1 %% of sales 22.6% 23.5% General and administrative $29.9 $26.6 12.4 %% of sales 8.4% 7.5% Medical device excise tax $4.1 $3.8 7.9 %% of sales 1.2% 1.1% 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 andsold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead. The $2.8million decrease compared to 2014 is mostly attributable to a $4.8 million charge related to Morpheus PICC inventory on hand at the time of the productdiscontinuance. Further decreases were the result of currency exchange fluctuations which negatively impacted our sales with minimal reduction to our cost ofsales. These headwinds were partially offset by product cost reductions generated by our active Operational Excellence program and favorable shifts in productmix.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. The decrease in R&D costs for the year ended May 31,2015 relates to savings generated by restructuring activities in 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. Decreases in S&M expense for the year ended May 31, 2015 is the result of areorganization of our international sales organization, combined with the impact of attrition in our U.S. sales force. While the U.S. sales force attrition benefitedour operating expenses in fiscal 2015, retaining our sales employees is important to our long-term revenue growth and operating results.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 for theyear ended May 31, 2015 are primarily the result of higher depreciation and maintenance expenses particularly as a result of the ERP implementation in the prioryear and increased incentive and stock-based compensation costs.Medical device excise tax - Medical device excess tax is assessed on our U.S. product sales subject to exclusions and adjustments. The slight increase ascompared to the prior year is attributable to the mix of taxable products within the U.S. market.

Fiscal 2015 included $10.5 million ingains recognized as a result of reducing the estimated present value of future payments due on earn-outs, representing a $5.5 million increase as compared to $5.0million gain recorded in fiscal 2014. These gains were partially offset in each period by amortization of the present value discount on the contingent liabilities.Acquisition, restructuring and other items, net - Expense for fiscal 2015 consists of $9.1 million of fixed and long-term asset impairments, $6.4 million ofimpairment on the NAMIC trademark, other costs associated with litigation, the recall of Morpheus, our operational excellence program, and other miscellaneousitems. The impairment charges were primarily driven by a change in strategy within our fluid management product development pipeline, as we moved away fromour planned design of an Automated Power Injector.Other expenses - Other expenses include interest expense, credit card processing fees, foreign currency impacts, bank fees, and amortization of deferredfinancing costs. Expenses were consistent year over year in amount and composition. For year ended May 31, 2015 2014Income tax expense (benefit) $(4.7) $3.1Effective tax rate including discrete items 59% 54%Income tax provision (benefit) - Our effective tax rate was 59% for fiscal 2015 compared with 54% for the prior year. The current year rate reflects thebenefit of the $9.2 million nontaxable adjustment to the contingent liabilities related to Vortex Medical and Clinical Devices, and a seven month benefit from theR&D tax credit that expired on December 31, 2014, offset by non-deductible interest expense related to contingent payments, true-ups of our fiscal year 2014 USincome tax returns and the impact of the elimination of the ASC 718 APIC pool. The prior year rate reflects the benefit of the $5.0 million nontaxable adjustmentto the contingent liability related to Vortex Medical, Inc., offset by the impact of a New York State tax law change that resulted in a $1.2 million net write off oftax assets, non-deductible interest expense related to contingent payments, a seven month benefit from the R&D tax credit that expired on December 31, 2013, trueups of our fiscal year 2013 US income tax returns and the impact of the elimination of the ASC 718 APIC pool.Results of Operations for the years ended May 31, 2014 and 2013For the fiscal year ended May 31, 2014 , we reported net income of $2.7 million, or $0.08 per basic and diluted common share, on net sales of $354.4 millioncompared to a fiscal 2013 net loss of $1.2 million, or ($0.03) per basic and diluted common share, on net sales of $341.9 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, 2014 and 2013 :36 For the years ended May 31, 2014 % of NetSales 2013 % of NetSalesNet Sales by Product Category Peripheral Vascular$192,626 54% $179,573 53% Vascular Access106,394 30% 106,690 31% Oncology/Surgery49,360 14% 47,155 14%Total Excluding Supply Agreement348,380 98% 333,418 98% Supply Agreement6,045 2% 8,498 2% Total$354,425 100% $341,916 100% Net Sales by Geography United States$280,161 79% $266,228 78% International68,219 19% 67,190 20% Supply Agreement6,045 2% 8,498 2% Total$354,425 100% $341,916 4%Net sales are derived from the sale of our products and related freight charges, less discounts and estimated sales returns and allowances. Net sales for fiscal2014 of $354.4 million, increased 4% over fiscal 2013 sales of $341.9 million. This increase was primarily attributable to increased sales of EVLT procedure kits,sales of the recently introduced AngioVac product and increased microwave product sales. These overall increases were partially offset by decreased sales of fluidmanagement and RFA products as well as a decrease in products sold through our supply agreement.From a product line perspective, Peripheral Vascular sales increased 7% to $192.6 million from the prior year. This increase was primarily attributable tosales of EVLT procedure kits and sales of the recently introduced AngioVac product. Vascular Access sales were consistent at $106.4 million in fiscal 2014 ascompared to $106.7 million in the prior year. Oncology/Surgery sales were $49.4 million, an increase of 5% from the prior year and is primarily due to increasedsales of our microwave and NanoKnife products, partially offset by a decline in the radiofrequency ablation products.From a geographic perspective, U.S. sales increased 5% to $280.2 million in fiscal 2014 compared to $266.2 million in fiscal 2013, again attributable toEVLT and AngioVac performance. International sales increased 2% to $68.2 million in fiscal 2014 primarily due to increased sales of PICCs, microwave andNanoKnife products, partially offset by radiofrequency ablation declines.Gross Profit, Operating expenses, and Other income (expense) For the year ended May 31, 2014 2013 % ChangeGross profit $179.7 $168.5 6.6%Gross profit % of sales 50.7% 49.3% Research and development $27.5 $26.3 4.6%% of sales 7.8% 7.7% Selling and marketing $83.2 $76.1 9.3%% of sales 23.5% 22.3% General and administrative $26.6 $26.2 1.5%% of sales 7.5% 7.7% Medical device excise tax $3.8 $1.6 137.5%% of sales 1.1% 0.5% 37Gross profit - Gross profit consists of net sales less the cost of goods sold, which includes the costs of materials, products purchased from third parties andsold by us, manufacturing personnel, royalties, freight, business insurance, depreciation of property and equipment and other manufacturing overhead. Our grossprofit as a percentage of sales was 50.7% in fiscal 2014 compared with 49.3% in fiscal 2013. The increase in gross profit percentage in fiscal 2014 was primarilyattributable to $3.8 million in step-up basis amortization related to Navilyst inventory acquired in the prior year, as well as growth in higher margin products suchas AngioVac.Research and development expenses - Research and development (“R&D”) expenses include costs to develop new products, enhance existing products,validate new and enhanced products, manage clinical, regulatory and medical affairs. R&D expenses increased by $1.2 million, or 4.4%, to $27.5 million in fiscal2014 compared to the prior year. The increase is primarily due to increased R&D spending on clinical trials and other new product development. As a percentageof net sales, R&D expenses were 7.8% for fiscal 2014, compared to 7.7% for fiscal 2013.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 samples. S&M expenses increased $7.1 million or 9.3% to $83.2 million in fiscal 2014 comparedto $76.1 million in fiscal 2013. This increase is primarily due to investments made during fiscal 2013 in the US and International sales forces to drive improvedsales performance. In addition, the geographic mix of sales created higher commission expense as compared to the prior year period. As a percentage of net sales,S&M expenses were 23.5% for fiscal 2014 compared to 22.3% for fiscal 2013.General and administrative expenses - General and administrative (“G&A”) expenses includes the cost of executive management, finance, accounting, legal,human resources and information technology and the administrative and professional costs associated with those activities. G&A expenses increased byapproximately $0.5 million when compared to fiscal 2013. G&A expenses decreased to 7.5% of net sales in fiscal 2014 when compared to 7.7% of net sales infiscal 2013.Medical device excise tax - Fiscal 2014 and 2013 included $3.8 million and $1.6 million of expense attributed to the Medical Device Excise Tax enacted intolaw effective January 1, 2013. For the year ended May 31, 2014 2013 $ ChangeAmortization of intangibles $16.6 $16.6 $—Change in fair value of contingent consideration $(1.8) $1.6 $(3.4)Acquisition, restructuring and other items, net $10.8 $13.8 $(3.0)Other expense $(7.2) $(7.9) $0.7Change in fair value of contingent consideration - The fiscal 2014 results include a net benefit of $1.8 million as a result of a $5 million gain uponrevaluation of the Vortex contingent consideration based on a revised sales forecast. This gain was partially offset by changes in fair value of the contingentconsideration associated with Microsulis and Clinical Devices. Fiscal 2013 included expenses of $1.6 million related to the change in fair value of the contingentconsideration associated with the Vortex and Microsulis acquisitions.Acquisition, restructuring and other items, net - Acquisition, restructuring and other items, net totaled $10.8 million for fiscal 2014 and primarily consisted of$6.1 million in acquisition costs, $2.2 million in litigation costs and $1.4 million in costs related to our NY plant consolidation program. Fiscal 2013 acquisition,restructuring and other items totaled $13.8 million and primarily includes $7.6 million in transaction and related costs of the Navilyst and Microsulis acquisitions,$2.5 million in costs associated with the closure of the Cambridge, UK facility, $1.6 million in impairment costs associated with a discontinuance of a productoffering and $1.4 million in litigation costs.Other expenses - Other expenses for fiscal 2014 totaled $7.2 million, or 2% of net sales compared to fiscal 2013 results of $7.9 million, or 2.3% of net sales.The decrease is due to a reduction in interest expense as a result of our recent debt refinancing but was offset by increases in other expenses.38 For year ended May 31, 2014 2013Income tax expense (benefit) $3.1 $(0.4)Effective tax rate including discrete items 54% 24%Income tax provision (benefit) - Our effective tax rate was 54% for fiscal 2014 compared with 24% for the prior year. The current year rate reflects thebenefit of the $5.0 million nontaxable adjustment to the contingent liability related to Vortex Medical, Inc., offset by the impact of a New York State tax lawchange that resulted in a $1.2 million net write off of tax assets, non-deductible interest expense related to contingent payments, decreased non-US income, a sevenmonth benefit from the R&D tax credit that expired on December 31, 2013, true ups of our fiscal year 2013 US income tax returns and the impact of theelimination of the ASC 718 APIC pool. Our ASC 718 APIC pool, which has been historically reduced when share-based compensation cost previously recognizedby us was greater than the deduction allowed for income tax purposes based on the price of our common stock on the date of exercise or vesting, is fully depleted.This depletion resulted in a discrete tax expense in fiscal 2014. The prior year rate reflects the impact of non-deductible costs related to the acquisition of Vortex,non-deductible interest expense related to contingent payments, the utilization of fully reserved capital losses, increased non-US income, the retroactive renewal ofthe previously expired R&D tax credit, the elimination of the Domestic Production Activities Deduction caused by reduced taxable income and the larger impact ofnon-deductible expenses also caused by the reduced taxable income in fiscal 2013.During the fiscal third quarter of 2013, The American Taxpayer Relief Act of 2012 was enacted and retroactively extended the research credit from January1, 2012 to December 31, 2013. This legislation led to a prior period tax benefit in fiscal 2013 of $73,000 for the research credit generated from January 1, 2012 toMay 31, 2012. This credit has not been renewed since the December 31, 2013 expiration.Liquidity and Capital ResourcesOur cash and cash equivalents totaled $18.4 million as of May 31, 2015 , compared with $16.1 million as of May 31, 2014 . Marketable securities totaled$1.7 million and $1.8 million for the years ended May 31, 2015 and May 31, 2014 , respectively, and consist of auction rate securities. As of May 31, 2015 , totaldebt was $137.7 million comprised of a term loan and revolving credit facility. The fair value of contingent consideration payments as of May 31, 2015 was $47.4million .The table below summarizes our cash flows for the years ended May 31, 2015 , 2014 and 2013 : For the year ended May 31, 2015 2014 2013Cash provided by (used in): Operating activities$26,242 $24,681 $26,652Investing activities(13,293) (16,448) (22,238)Financing activities(10,465) (14,016) (6,286)Effect of exchange rate changes on cash and cash equivalents(198) 86 (65)Net change in cash and cash equivalents$2,286 $(5,697) $(1,937)Cash provided by operating activities during the twelve months ended May 31, 2015 and 2014 was primarily the result of net loss excluding non-cash itemsoffset by unfavorable shifts in working capital. In the current year, favorable working capital changes in accounts receivable was partially offset by increases ininventories and other assets and reductions in payables and accrued expenses.The net cash used in investing activities for the current year period consisted of $11.9 million in fixed asset additions, a large portion of which is associatedwith facility investments, and $1.4 million in intangible asset additions. The prior year use of cash consisted primarily of $11.2 million of fixed asset additions,particularly the ERP implementation, $4.2 million as part of the Clinical Devices acquisition and $1.4 million in intangible asset additions.The net cash provided by financing activities is the result of $11.2 million in payments on contingent liabilities and $5.0 million of net repayments on ourcredit facility, partially offset by $5.8 million of stock option and ESPP activity proceeds.39We believe that our current cash and investment balances, together with cash generated from operations and our remaining revolving credit facility capacityof $53.6 million as of May 31, 2015, will provide sufficient liquidity to meet our anticipated needs for capital for at least the next 12 months. If we seek to makesignificant acquisitions of other businesses or technologies in the future for cash, we may require external financing.Our contractual obligations as of May 31, 2015 are set forth in the table below (in thousands). We have no variable interest entities or other off-balance sheetobligations. Cash Payments Due By Period as of May 31, 2015 Total Less thanOne Year 1-3 Years 3-5 Years After 5YearsContractual Obligations: Long term debt and interest$144,646 $11,288 $133,358 $— $—Operating leases(1)9,896 2,191 5,956 1,749 —Purchase obligations(1)9,940 9,940 — — —Acquisition-related future obligations (2)54,005 10,100 25,164 9,822 8,919 $218,487 $33,519 $164,478 $11,571 $8,919 (1)The non-cancelable operating leases and inventory purchase obligations are not reflected on our consolidated balance sheets under accounting principlesgenerally accepted in the United States of America.(2)Acquisition-related future obligations include scheduled minimum payments and contingent payments based upon achievement of performance measures ormilestones such as sales or profitability targets, the achievement of research and development objectives or the receipt of regulatory approvals.

Timing of payments are as contractually scheduled, or wherecontingent, the Company's best estimate of payment timing.Recent Accounting PronouncementsIn February 2013, the FASB expanded the disclosure requirements related to changes in accumulated other comprehensive income (AOCI). The newguidance requires disclosure of the amount of income (or loss) reclassified out of AOCI to each respective line item on the statement of operations where netincome is presented. The guidance allows disclosure of the reclassification either in the notes to the financial statements or parenthetically on the face of thefinancial statements. This requirement is effective for reporting periods beginning after December 15, 2012 (fourth quarter of our fiscal year 2013). The adoptiondid not have a material impact on our consolidated financial statements.In July 2013, the FASB issued guidance related to the presentation of certain tax information. This new pronouncement provides explicit guidance on thefinancial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, or similar tax loss, or a tax credit carryforward exists. Thispronouncement is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2013 (our fiscal year 2015). Since theguidance only impacts presentation requirements, its adoption will not have a material impact on our consolidated financial statements.In May 2014, the Financial Accounting Standards Board ("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 revenuerecognition guidance, including industry-specific guidance. Under this model, revenue is recognized at an amount that an entity expects to be entitled to upontransferring control of 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 is effective for the Company beginning in its fiscal year 2018, and may be applied retrospectively to all prior periods presented or through acumulative adjustment to the opening retained earnings balance in the year of adoption. The Company is currently in the process of evaluation the impact of ASU2014-09 on its consolidated financial statements.In April 2015, the FASB issued ASC Update No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt IssuanceCosts. Update No. 2015-03 requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from thecarrying amount of that debt liability, consistent with debt discounts. Update No. 2015-03 is effective for annual reporting periods beginning after December 15,2015 and interim periods within those reporting periods. Early adoption is permitted for financial statements that have not been previously issued. The40adoption of Update No. 2015-03 will require us to reclassify our debt issuance costs from deferred charges to direct deductions of our debt liabilities. This update isnot expected to impact the results of our operations. Item 7A.Quantitative and Qualitative Disclosures about Market Risk.We are exposed to market risk from changes in currency exchange rates, as well as interest rate fluctuations on our credit facility and investments that couldimpact our results of operations and financial position.We transact sales in currencies other than the U.S. Dollar, particularly the Euro, British pound and Canadian dollar. Approximately 8% of our sales in fiscal2015 were denominated in foreign currencies. We do not have expenses denominated in foreign currencies at the level of our sales and as a result, our profitabilityis exposed to currency fluctuations. When the U.S. Dollar strengthens, our sales and gross profit will be negatively impacted. In addition, we have assets andliabilities denominated in non-functional currencies which are remeasured at each reporting period, with the offset to changes presented as a component of OtherIncome (Expenses). Significant non-functional balances include a Euro denominated contingent liability and accounts receivable due from a sub-section of ourinternational customers.In June 2012, we entered in an interest rate swap agreement, with an initial notional amount of $100 million, to limit the effect of variability due to interestrates on our debt. The swap agreement, which qualifies for hedge accounting under authoritative guidance, is a contract to exchange floating interest rate paymentsfor fixed interest rate payments of 3.26% of the outstanding balance of loan over the life of the swap agreement without the exchange of the underlying notionalamounts. We do not currently engage in any other hedging or market risk management tools.On September 19, 2013, we entered into a Credit Agreement (the "Credit Agreement")which provides for a $100 million senior secured term loan facility (“Term Loan") and a $100 million senior secured revolving credit facility (the “Revolving Facility", and together with the Term Loan, the "Facilities"). Interest onboth the Term Loan and Revolver will be based on a base rate or Eurodollar rate plus an applicable margin which increases 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 the event of default, the interest rate may be increasedby 2.0%. Changes in the interest rate would not be material.Our excess cash is invested in highly liquid, short-term, investment grade securities with maturities primarily of less than two years. These investments arenot held for speculative or trading purposes. Changes in interest rates may affect the investment income we earn on cash, cash equivalents and marketablesecurities and therefore affect our cash flows and results of operations. We hold investments in auction rate securities (“ARS”) in order to generate higher thantypical money market investments. ARS typically are high credit quality, generally issued with municipal bond insurance. Credit risks are eased by the historicaltrack record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction process could exceed bids. Suchinstances are usually the result of a drastic deterioration of issuer credit quality. Should there be a failed auction, we may be unable to liquidate our position in thesecurities in the near term. We have $1.7 million in investments in two auction rate securities issued by New York state and local government authorities that havefailed auctions. The authorities are current in their interest payments on the securities.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. Item 9.Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.None. Item 9A.Controls and Procedures.Evaluation of disclosure controls and proceduresAs of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer andour Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of theSecurities Exchange Act of 1934, as amended. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosurecontrols and procedures as of the end of the period covered by this report were effective to provide reasonable assurance that the information required to bedisclosed by us in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periodsspecified in the SEC rules and forms and is accumulated and communicated41to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.Management’s Report on Internal Control Over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting for our company. Internal control overfinancial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended, as a process designed by, orunder the supervision of, our principal executive and principal financial officers and effected by our board of directors, management and other personnel, toprovide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance withaccounting 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 of ourmanagement 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 any evaluationof effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate.Our management has assessed the effectiveness of our internal control over financial reporting as of May 31, 2015. 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, 2015.The effectiveness of our internal control over financial reporting as of May 31, 2015 has been audited by PricewaterhouseCoopers LLP, an independentregistered public accounting firm, as stated in their report which appears herein.Remediation of Prior Material Weakness in Internal Control Over Financial ReportingManagement of the Company previously identified and disclosed the following material weaknesses that existed as of May 31, 2014.We did not maintain effective controls over the preparation, review and approval of certain account reconciliations. Specifically, the Companydid not maintain effective controls over the completeness and analysis of supporting schedules and underlying data supporting account reconciliationsprepared for certain prepaid expenses and other assets and fixed assets and accumulated depreciation.We lacked a sufficient complement of personnel with a level of financial reporting expertise commensurate with our financial reportingrequirements, specifically, with respect to resources capable of: monitoring and accurately recording certain routine transactions specifically in prepaidexpenses and other assets, fixed assets and accumulated depreciation; evaluating the presentation and disclosure of contingent consideration liabilitiesand intangible assets; effectively performing testing related to our enterprise resource planning ("ERP") implementation specifically associated with theconfiguration of certain intercompany transactions and the conversion of data related to depreciation; and properly performing account reconciliationsas noted above.During 2015, management of the Company has been actively engaged in the implementation of remediation efforts to address the material weaknessesnoted above. The following actions were taken:•Hired additional full-time and temporary accounting resources with appropriate levels of experience, including a new Global Controller, AssistantController, Senior Accounting Manager and Tax Director to drive improvement of and oversee day-to-day accounting activities.•Implemented an account reconciliation policy and monitoring program.•Added financial planning and analysis resources to strengthen our overall internal control environment.42•Reallocated responsibilities across our accounting organization to ensure the appropriate level of knowledge and experience is applied based on risk andcomplexity.•Commenced a detailed review of our ERP to identify opportunities to improve the accuracy of routine transaction processing, specifically with respect toaccounting transactions related to purchasing and payables.Based upon the significant actions taken and the testing and evaluation of the effectiveness of our internal control over financial reporting, management ofthe Company has concluded the material weaknesses in the Company’s controls no longer existed as of May 31, 2015.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, 2015 that has materially affected, or isreasonably likely to materially affect, our internal control over financial reporting.Item 9B.Other Information.None.43Part 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 120 daysafter the end of our fiscal year end pursuant to Regulation 14A (the “Proxy Statement”) for our annual meeting of Stockholders, currently scheduled forOctober 2015.

In addition, in our opinion, the financial statement schedule listed in the index appearingunder Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financialstatements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of May 31, 2015, based oncriteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission(COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control overfinancial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control overFinancial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and onthe Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the PublicCompany Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whetherthe financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessingthe accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internalcontrol over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such otherprocedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and thepreparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financialreporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactionsand dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financialstatements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance withauthorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorizedacquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance withthe policies or procedures may deteriorate./s/ PricewaterhouseCoopers LLPBoston, MassachusettsAugust 10, 201546AngioDynamics, Inc. and SubsidiariesCONSOLIDATED STATEMENTS OF OPERATIONS(in

FINANCIAL STATEMENTSNOTE A—BASIS OF PRESENTATION, BUSINESS DESCRIPTION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES1. Basis of Presentation and Description of BusinessThe consolidated financial statements include the accounts of AngioDynamics, Inc. and its wholly owned subsidiaries, (collectively, the “Company”). Wedesign, manufacture and sell a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for thetreatment of peripheral vascular disease and in oncology and surgical settings. 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 long-term use.The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management tomake estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of theconsolidated financial statements. Estimates also affect reported amounts of sales and expenses during the reporting period. Actual results could differ from thoseestimates.Assets and liabilities of non-U.S. dollar functional currency entities are translated to U.S. dollars at period-end exchange rates, and the resulting gains andlosses arising from the translation of those net assets are recorded as a cumulative translation adjustment, a component of accumulated other comprehensive loss onthe consolidated balance sheets.All intercompany balances and transactions have been eliminated.2. Cash and Cash EquivalentsWe consider all unrestricted highly liquid investments purchased with an initial maturity of less than three months to be cash equivalents. We maintain cashand cash equivalent balances with financial institutions in the United States in excess of amounts insured by the Federal Deposit Insurance Corporation.3. Marketable SecuritiesMarketable securities, which include auction rate investments, are classified as “available-for-sale securities” and are reported at fair value, with unrealizedgains and losses excluded from operations and reported as a component of accumulated other comprehensive income (loss), net of the related tax effects, instockholders’ equity. Cost is determined using the specific identification method. We hold investments in auction rate securities in order to generate higher thantypical money market rate investment returns. Auction rate securities typically are high credit quality, generally achieved with municipal bond insurance. Creditrisks are eased by the historical track record of bond insurers, which back a majority of this market. Sell orders for any security traded through an auction processcould exceed bids and, in such cases, the auction fails and we may be unable to liquidate our position in the securities in the near term. During fiscal years 2015and 2014 , we had $1.7 million and $1.8 million , respectively, in investments in two auction rate securities issued by New York state and local governmentauthorities that failed auctions. The authorities are current in their interest payments on the securities.4. Accounts ReceivableAccounts receivable, principally trade, are generally due within 30 to 90 days and are stated at amounts due from customers, net of an allowance for salesreturns and doubtful accounts. We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history and the customer’scurrent creditworthiness, as determined by a review of their current credit information. We continuously monitor aging reports, collections and payments fromcustomers, and a provision for estimated credit losses is maintained based upon our historical experience and any specific customer collection issues that have beenidentified. While such credit losses have historically been within our expectations and the provisions established, we cannot guarantee that the same credit lossrates will be experienced in the future. We write off accounts receivable when they are determined to be uncollectible.5. 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.536. Property, Plant and EquipmentProperty, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimateduseful 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 yearsWe evaluate these assets for impairment periodically or as changes in circumstances or the occurrence of events suggest the remaining value is notrecoverable. Expenditures for repairs and maintenance are charged to expense as incurred. Renewals and betterments are capitalized.7. Goodwill and Intangible AssetsIntangible assets other than goodwill and acquired IPR&D are amortized over their estimated useful lives, which range between three and fifteen years, oneither a straight-line basis over the expected period of benefit or as revenues are earned from the sales of the related products. We periodically review the estimateduseful lives of our intangible assets and review such assets for impairment whenever events or changes in circumstances indicate that the carrying value of theassets is not recoverable. Our determination of impairment is based on estimates of future cash flows. If an intangible asset is considered to be impaired, theamount of the impairment will equal the excess of the carrying value over the fair value of the asset.Acquired IPR&D has an indefinite life and is not amortized until completion of the development of the project, at which time the IPR&D becomes anamortizable asset. If the related project is not completed in a timely manner or the project is terminated or abandoned, we may have an impairment related to theIPR&D, calculated as the excess of the asset’s carrying value over its fair value.Our policy defines IPR&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 IPR&D requires us to make significant estimates. The amount of the purchaseprice allocated to IPR&D is determined by estimating the future cash flows of each project or technology and discounting the net cash flows back to their presentvalues. The discount rate used is determined at the time of measurement in accordance with accepted valuation methods. These methodologies includeconsideration 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 more frequently ifimpairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquiredin each business combination. Goodwill and intangible assets have been recorded at either incurred or allocated cost. Allocated costs were based on respective fairmarket 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 of thecarrying value of the assets and liabilities of that unit. If the sum of the carrying value of the assets and liabilities of a reporting unit exceeds the fair value of thereporting unit, the carrying value of the reporting unit’s goodwill is reduced to its implied fair value through an adjustment to the goodwill balance, resulting in animpairment charge. Our determination of impairment is based on estimates of future cash flows.8. Contingent ConsiderationThe fair value of the liability for contingent consideration recorded on the acquisition date is based on probability weighted estimated cash flow streams,discounted back to present value using a discount rate determined in accordance with accepted valuation methods. The liability for contingent consideration isremeasured to fair value at each reporting period with changes recorded in earnings until the contingency is resolved.9. Revenue RecognitionWe recognize revenue when the following four criteria has been met: (i) persuasive evidence that an arrangement exists; (ii) the price is fixed ordeterminable; (iii) collectability is reasonably assured; and (iv) product delivery has occurred or services have been rendered. We recognize revenue, net of salestaxes assessed by any governmental authority, as products are shipped, based on shipping terms, and 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-approved54by us and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least twelvemonths remaining prior to its expiration date. Charges for discounts, returns, rebates and other allowances are recognized as a deduction from revenue on anaccrual basis 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.Sales rebates are accrued by the company in the period in which the sale is recorded.Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized whenthe related finished product is shipped to the customer. Amounts charged to customers for shipping are recorded in net sales.10. Research and DevelopmentResearch and development costs, including salaries, consulting fees, building costs, utilities and administrative expenses that are related to developing newproducts, enhancing existing products, validating new and enhanced products, managing clinical, regulatory and medical affairs are expensed as incurred.11. Income TaxesIn preparing our financial statements, we calculate income tax expense for each jurisdiction in which we operate. This involves estimating actual currenttaxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets andliabilities. We periodically evaluate deferred tax assets, capital loss carryforwards and tax credit carryforwards to determine their recoverability based primarily onour ability to generate future taxable income and capital gains. Where their recovery is not likely, 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 2011 through 2015 remain open to examination by the various tax authorities. New York Stateis currently auditing AngioDynamic’s franchise tax filings for 2011 through 2014, and we do not anticipate any material adjustments will result. We analyzedfiling 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 these jurisdictions and believethat our income tax filing positions and deductions will be sustained on audit and we do not anticipate any adjustments will result in a material adverse effect onour financial condition, results of operations or cash flows.We do not anticipate that the amount of unrecognized tax benefits will significantly change in the next twelve months.12. Derivative Financial InstrumentsWe are exposed to market risks, including changes in interest rates. We periodically enter into certain derivative financial instruments to hedge theunderlying economic exposure. The derivative instruments used are floating-to-fixed rate interest rate swaps, which are subject to hedge accounting treatment.Derivative instruments are presented in the consolidated financial statements at their fair value. Changes in the fair value of derivative financial instrumentsare either recognized periodically in income or in stockholders’ equity as a component of accumulated other comprehensive income (loss) depending on whetherthe 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 thefair value of derivatives accounted for as fair value hedges are recorded in income along with the portions of the changes in the fair value of hedged items thatrelate to the hedged risks. Changes in the fair value of derivatives accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded inaccumulated other comprehensive income (loss).13. Supplier ConcentrationsWe are dependent upon the ability of our suppliers to provide products on a timely basis and on favorable pricing terms. The loss of our principal suppliersor a significant reduction in product availability from these suppliers could have a material adverse effect on us. We believe that our relationships with thesesuppliers are satisfactory.14. ReclassificationCertain prior period disclosures have been reclassified to conform to current year presentation. These reclassifications are considered immaterial.5515. Recent EventsOperational Excellence Program - On December 5, 2013, we announced a company-wide operational excellence program designed to save between $15.0and $18.0 million during the course of the next three years and expected to create greater efficiencies and drive business performance improvements. (See Note Qof Notes to Consolidated Financial Statements for more information related to the restructuring.)Morpheus PICC recall and product line discontinuance - during the quarter ended February 28, 2015 we made a decision to voluntarily recall our MorpheusPICC product line and concurrently discontinue the product. The recall decision was made following an internal evaluation commenced as a result ofcommunications from two international regulatory bodies which noted product complaints. Based on the evaluation performed and the lack of clear root cause, wedetermined the best course of action was to recall the product. Further, consistent with our strategy to transition toward our transformational BioFlo productofferings, we decided to discontinue the Morpheus line. The result was $6.1 million in charges during the year, including $4.8 million of inventory write-offsincluded in “Cost of sales”, as well as $1.0 million of costs associated with product returns, storage costs and other expenses which are included in “Acquisition,Restructuring and Other Items, net”.Automated Power Injector - over the last several years we have invested in the development of a new technology which was intended to create atransformational shift in our fluid management product line. As a result of recent concerns related to an extended and difficult path to regulatory approval for thedifferentiating technology, we evaluated the long-term opportunity, as well as the expected risk and costs associated with bringing this technology to market. Basedon that evaluation, in the quarter ended February 28, 2015 we made a decision to shift away from this technology toward other strategies and opportunities withinthe fluid management market. As a result we no longer expect cash flows to be generated by certain fixed assets and recorded a full impairment charge of $8.2million in the third quarter. In addition, the sales projected on this product were a significant portion of the long-term sales projections under the NAMIC brand.The NAMIC trademark was acquired in the Navilyst Medical acquisition and was accounted for as an indefinite lived intangible asset with a value of $28.6 millionat that time. Primarily as a result of the reduction in expected NAMIC product sales driven by the discontinuance of this project, we recorded an impairment chargeof $6.4 in the third quarter.EmboMedics, Inc. - on March 2, 2015, the Company filed an 8-K stating that it executed a non-binding letter of intent to enter into a strategic relationshipwith privately-held EmboMedics Inc., which develops injectable and resorbable embolic microspheres. On April 9, 2015 the Company entered into a License,Distribution, Manufacturing and Purchase Option Agreement with EmboMedics Inc, subject to certain approvals by EmboMedics shareholders.Under the terms of the agreement, which has not been finalized, AngioDynamics receives an exclusive worldwide license to market and sell, uponregulatory clearances, EmboMedics’ microsphere technology. AngioDynamics will also control manufacturing of the products. AngioDynamics will make aninitial $2.0 million equity investment in EmboMedics through the purchase of preferred stock. The Company may make an additional $9.0 million in equity, aswell as milestone driven investments, and can execute an exclusive option to acquire EmboMedics, based on the achievement of certain milestones.Regulatory MattersOn May 27, 2011, we received a Warning Letter from the U.S. Food and Drug Administration ("FDA") in connection with its inspection of our Queensbury,NY manufacturing facility. In the Warning Letter, FDA cited deficiencies in the response letter we provided FDA pertaining to the inspection that occurred fromJanuary 4 to January 13, 2011. The deficiencies related to our internal procedures for medical device reporting, corrections and removals and complaint handling.We responded to the Warning Letter and completed corrective and preventive actions to address the observations noted.In December 2011, we initiated a comprehensive Quality Call to Action Program to review and augment our Quality Management Systems at ourQueensbury facility. To accelerate implementation of the program, we engaged a team of external regulatory and quality experts and reallocated a significantnumber of engineering and product development resources to support this corporate initiative. From inception of the Quality Call to Action Program through fiscal2014, we have incurred $3.2 million in direct costs associated with the program.On February 10, 2012, we received from FDA a Form 483, List of Investigational Observations, in connection with its inspection of our Queensbury facilityfrom November 14, 2011 to February 10, 2012. The Form 483 contained 12 observations related to, among other things, our CAPA (Corrective and PreventiveAction) system, MDR (Medical Device Reporting),56complaint investigation, corrections and removals, acceptance criteria and training. Some of the observations contained in the Form 483 were repeat observationsfrom the May 27, 2011 Warning Letter described above.On February 13, 2012, we received from FDA a Form 483 in connection with its inspection of our Fremont facility from January 12, 2012 to February 13,2012. The Form 483 contained six observations related to, among other things, our CAPA system, design controls, risk management and training. We providedresponses to FDA within 15 business days of our receipt of the Form 483s.On September 24, 2012, we received from FDA a Form 483 in connection with its subsequent inspection of our Queensbury, NY facility from September 6to September 14, and September 19 to September 24. This re-inspection followed our response to the original Form 483 issued by FDA on February 13, 2012. TheForm 483 contained 5 observations related to 510(k) decisions, complaint investigations, acceptance criteria, corrective and preventive actions and training. All butone of the observations in the Form 483 related to events that occurred before the date that we had indicated to FDA in our previous responses that our correctiveand remediation activities related to our Quality Call to Action would be completed. We provided responses to FDA within 15 business days of our receipt of theForm 483.On February 4, 2014, FDA completed a comprehensive follow-up inspection of our Queensbury facility. The inspection began on January 14, 2014 andresulted in FDA issuing a Form 483 containing one observation. The observation related to the inconsistency of certain complaint investigation elements in certaindevices that have hardware and disposable components. The Form 483 observation was annotated to reflect that during the inspection we had corrected the issue,and this correction was verified by the inspector. In addition, we provided a response to FDA within 15 business days of our receipt of the Form 483. We believethat the results of this inspection validate that all of the Quality System and current Good Manufacturing Practice issues raised in the 483s described above havebeen fully addressed.On March 31, 2014, FDA completed an inspection of our Glens Falls, NY facility. The inspection began on March 17, 2014 and resulted in FDA issuing aform 483 containing 3 observations. The observations were related to 1) inconsistency of a manufacturing product test process used among similar products, 2) aparticular verification test of a product, and 3) non-conforming product control procedure. We responded to the FDA within 15 business days of the receipt of theForm 483.During the fourth quarter of our fiscal year ended May 31, 2014, we received Certificate to Foreign Governments ("CFGs") from the FDA covering allVascular Access and Peripheral Vascular products manufactured in our Queensbury facility. During the first quarter of our fiscal year ending May 31, 2016, wereceived CFGs for our NanoKnife product.On November 5, 2014, we received a Warning Letter from the FDA relating to observations noted during FDA’s inspection of our Navilyst Medical facilitieslocated in Marlborough, Massachusetts and Glens Falls, New York in 2014. The matters raised in the Warning Letter and observations focused on design controlprocesses related to packaging validations and accelerated and real time aging testing in connection with our fluid management and PICC families of products,inconsistency of a manufacturing product test process used among similar valved PICC products, a particular verification test of valved PICC products and non-conforming product control procedures. We take these matters seriously and are committed to complying with all applicable laws, regulations and rules inconnection with the manufacturing, sale and marketing of our products. We made a comprehensive response to the issues raised in the letter and are committed toworking with FDA to resolve all outstanding issues.We will continue to work closely with FDA to resolve any outstanding issues. Unless the items raised in the previously disclosed Warning Letters and Form483s are corrected to FDA’s satisfaction or we come to some other arrangement with FDA finally resolving such matters, we may be subject to additionalregulatory or legal action, including the issuance of warning letters, injunction, seizure or recall of products, imposition of fines or penalties or operatingrestrictions on our facilities. Such actions could significantly disrupt our ongoing business and operations and have a material adverse impact on our financialposition and operating results.Recently Issued Accounting PronouncementsIn February 2013, the FASB expanded the disclosure requirements related to changes in accumulated other comprehensive income (AOCI). The newguidance requires disclosure of the amount of income (or loss) reclassified out of AOCI to each respective line item on the statement of operations where netincome is presented. The guidance allows disclosure of the reclassification either in the notes to the financial statements or parenthetically on the face of thefinancial statements. This requirement was effective for reporting periods beginning after December 15, 2012 (fourth quarter of our fiscal year 2013). Since theguidance only impacts disclosure requirements, its adoption did not have a material impact on our consolidated financial statements.57In July 2013, the FASB issued guidance related to the presentation of certain tax information. This new pronouncement provides explicit guidance on thefinancial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, or similar tax loss, or a tax credit carryforward exists. Thispronouncement was effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2013 (our fiscal year 2015). The adoptiondid not have a material impact on our consolidated financial statements.In May 2014, the Financial Accounting Standards Board ("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 revenuerecognition guidance, including industry-specific guidance. Under this model, revenue is recognized at an amount that an entity expects to be entitled to upontransferring control of 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 is effective for the Company beginning in its fiscal year 2018, and may be applied retrospectively to all prior periods presented or through acumulative adjustment to the opening retained earnings balance in the year of adoption. The Company is currently in the process of evaluation the impact of ASU2014-09 on its consolidated financial statements.In April 2015, the FASB issued ASC Update No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt IssuanceCosts. Update No. 2015-03 requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from thecarrying amount of that debt liability, consistent with debt discounts. Update No. 2015-03 is effective for annual reporting periods beginning after December 15,2015 and interim periods within those reporting periods. Early adoption is permitted for financial statements that have not been previously issued. The adoption ofUpdate No. 2015-03 will require us to reclassify our debt issuance costs from deferred charges to direct deductions of our debt liabilities. This update is notexpected to impact the results of our operations.NOTE B—ACQUISITIONSAcquisition of Clinical Devices, B.V.On August 15, 2013 we acquired all the outstanding shares of capital stock of Clinical Devices, B.V., exclusive distributor of our fluid management productsin the Netherlands. The stock purchase agreement provided for the payment of $3.7 million in cash at closing, which was subject to a working capital adjustmentand a $0.4 million holdback, plus future earn out consideration payable in cash. Earn out consideration is based on our net sales of the fluid management productsduring the five quarters following the closing as well as milestone payments for achieving regulatory approvals of certain in process research and development fora next-generation tip location technology. The total purchase consideration of $8.7 million includes an upfront payment and the estimated fair value of contingentconsideration of $5.0 million .Goodwill recorded as a result of the acquisition was approximately $4.8 million and is not deductible for tax purposes. Intangible assets acquired, other thangoodwill, totaled approximately $5.1 million , of which $3.6 million has been identified as in-process research and development, $1.4 million as customerrelationships (15-year estimated useful life) and $0.1 million as trademarks. We also recorded a deferred tax liability of $1.2 million .The acquisition has been accounted for as a business combination and, accordingly, we have included the results of operations in the financial statementseffective August 15, 2013. The pro forma effects of the acquisition on our income statement and balance sheet were not material.58NOTE C—FAIR VALUE OF FINANCIAL INSTRUMENTSOur financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable, interest rate swap agreement andcontingent earn outs. The carrying amount of cash and cash equivalents, accounts receivable, and accounts payable approximates fair value due to the immediate orshort-term maturities. The marketable securities and interest rate swap agreement has been recorded at its fair value based on a valuation received from anindependent third party. The contingent earn out has been recorded at fair value using the income approach.Fair value is the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous marketfor the asset or liability in an orderly transaction between market participants on the measurement date. This policy establishes a fair value hierarchy whichrequires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The policy describes threelevels of inputs that may be used to measure fair value which are provided in the table below. Level 1Quoted prices in active markets for identical assets or liabilities. Level 1 assets include money market funds that are traded in an activeexchange market.Level 2Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active;or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.When quoted market prices are unobservable, we obtain pricing information from an independent pricing vendor. The pricing vendor usesvarious pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions tothe model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealerquotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. The pricing vendor considers all available marketobservable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted prices, but ratherdetermined from market observable information. Included in Level 2 assets is our interest rate swap agreement which is valued using a mid-market valuation model.Level 3Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, orsimilar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.This category includes the auction rate securities where independent pricing information was not able to be obtained and the contingentconsiderations related to the acquisition of Vortex, Microsulis and Clinical Devices. Our investments in auction-rate securities were classifiedas Level 3 as quoted prices were unavailable since these auction rate securities issued by New York state and local government authoritiesfailed auction. Due to limited market information, we utilized a discounted cash flow (“DCF”) model to derive an estimate of fair value forcontingent considerations for all periods presented. The assumptions used in preparing the DCF model included estimates with respect to theamount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of fullrepayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own suchsecurities given the current liquidity risk associated with auction-rate securities.59The following tables provide information by level for assets and liabilities that are measured at fair value (in thousands): Fair Value Measurementsusing inputs considered as: Level 1 Level 2 Level 3 Fair Value at May 31,2015Financial Assets Marketable securities New York State government agency obligations$— $— $1,689 $1,689Total— — 1,689 1,689Total Financial Assets$— $— $1,689 $1,689Financial Liabilities Interest rate swap agreements$— $257 $— $257Contingent liability for acquisition earn out— — 47,384 47,384Total Financial Liabilities$— $257 $47,384 $47,641 Fair Value Measurementsusing inputs considered as: Level 1 Level 2 Level 3 Fair Value at May 31,2014Financial Assets Cash equivalents Money market funds$445 $— $— $445Total445 — — 445Marketable securities New York State government agency obligations— — 1,809 1,809Total— — 1,809 1,809Total Financial Assets$445 $— $1,809 $2,254Financial Liabilities Interest rate swap agreements$— $555 $— $555Contingent liability for acquisition earn out— — 67,331 67,331Total Financial Liabilities$— $555 $67,331 $67,886There were no transfers in and out of Level 1, 2 and 3 measurements for the years ended May 31, 2015 and 2014 .The components of Level 3 fair value instruments as of May 31, 2015 are shown below (in thousands): Financial Assets Financial Liabilities Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Fair Value Measurements Using Significant Unobservable InputsBalance at May 31, 2014$1,809 $67,331Change in fair value of contingent consideration (1)— (8,196)Currency (gain) loss from remeasurement— (529)Included in other comprehensive income (loss)(120) —Contingent consideration payments— (11,222)Balance at May 31, 2015$1,689 $47,38460The components of Level 3 fair value instruments as of May 31, 2014 are shown below (in thousands): Financial Assets Financial Liabilities Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Fair Value Measurements Using Significant Unobservable InputsBalance at May 31, 2013$1,850 $75,049Change in fair value of contingent consideration (1)— (1,808)New contingent consideration— 4,970Currency (gain) loss from remeasurement— —Included in other comprehensive income (loss)(41) —Contingent consideration payments— (10,880)Balance at May 31, 2014$1,809 $67,331(1) Change in the fair value of contingent consideration is included in earning and comprised of changes in estimated earn out payments based on projections ofcompany performance and amortization of the present value discount.Contingent Liability for Acquisition Earn OutsCertain of our 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 the acquiredcompany reaching certain performance milestones, including attaining specified revenue levels or achieving product development targets. Contingent considerationis recorded at the estimated fair value of the contingent milestone payments on the acquisition date. The fair value of the contingent milestone consideration isremeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within change in fair value ofcontingent consideration in the consolidated statement of operations. We measure the initial liability and remeasure the liability on a recurring basis using Level 3inputs as defined under authoritative guidance for fair value measurements.Contingent consideration liabilities will be remeasured to fair value each reporting period using projected net sales, discount rates, probabilities of paymentand projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected netsales are based on our internal projections and extensive analysis of the target market and the sales potential. Increases in projected net sales and probabilities ofpayment may result in higher fair value measurements in the future. Increases in discount rates and the projected time to payment may result in lower fair valuemeasurements in the future. Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in thefuture.The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant unobservable inputs as of May 31,2015 (in thousands of dollars): Fair value atMay 31, 2015 ValuationTechnique UnobservableInput RangeRevenue based payments$44,716 Discounted cash flow Discount rate Probability of payment Projected fiscal year of payment 4% 75% - 100% 2016 - 2022Milestone based payments2,668 Discounted cash flow Discount rate Probability of payment Projected fiscal year of payment 16% 75% - 100% 2017 $47,384 At May 31, 2015 , the estimated potential amount of undiscounted future contingent consideration that we expect to pay as a result of all completedacquisitions is approximately $54.0 million . The milestones associated with the contingent consideration must be reached in future periods ranging from fiscalyears 2016 to 2022 in order for the consideration to be paid.61NOTE D—MARKETABLE SECURITIES AND INVESTMENTSAs of May 31, 2015 , marketable securities consisted of the following: Amortizedcost GrossUnrealizedGains GrossUnrealizedLosses FairValue (in thousands)Available-for-sales securities New York State government agency obligations$1,825 $— $(136) $1,689 $1,825 $— $(136) $1,689As of May 31, 2014 , marketable securities consisted of the following: Amortizedcost GrossUnrealizedGains GrossUnrealizedLosses FairValue (in thousands)Available-for-sales securities New York State government agency obligations$1,825 $— $(16) $1,809 $1,825 $— $(16) $1,809The amortized cost and fair value of marketable securities as of May 31, 2015 , by contractual maturity, are shown below.

In conjunction with the OperationalExcellence Program that was announced in December 2013, we updated the estimated useful lives on certain manufacturing equipment. As a result of the change inthe useful life, we recoded additional depreciation of $1.5 million, $0.8 million and $0 million for the years ended May 31, 2015 , 2014 and 2013 , respectively.There was also an impairment of fixed assets, refer to Note A.63NOTE H—GOODWILL AND INTANGIBLE ASSETSWe consider our business to be a single operating segment entity as further described in Note P.Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growthrates, operating margins, discount rates and future market conditions, among others. These assumptions are highly sensitive and changes in these estimates couldresult in impairment. To determine the fair value of our reporting unit, we considered two market-based approaches and an income approach. Under the market-based approaches, we utilized information regarding our own as well as publicly available industry information to determine earnings multiples and salesmultiples. Under the income approach, we determined fair value based on estimated future cash flows of the reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. Wedetermined the discounted cash flow as the best indicator to determine fair value and therefore assigned a weight of 75% with the remaining 25% assigned to themarket approach.Solely for purposes of establishing inputs for the fair value calculations, we assumed that the current economic conditions would continue through fiscal year2015 . In addition, we applied gross margin assumptions, showing some improvement over historical trends, at various revenue levels and used a capitalization rateof 8% to calculate the terminal value of the reporting unit. In addition, we used a discount rate of 12% to calculate the fair value of our reporting unit. The fairvalue of the reporting unit was reconciled to our current stock market capitalization as of December 31, 2014.We completed our annual goodwill impairment test as of December 31, 2014. At December 31, 2014, our reporting unit is the same as our reportablesegment. Our assessment of goodwill impairment indicated that the fair value of our reporting unit exceeded its carrying value and therefore goodwill was notimpaired. The fair value of our reporting unit exceeded its carrying value by 18% .Our stock market capitalization has at times been lower than our shareholders’ equity or book value. However, our reporting unit has continued to generatesignificant cash flows from operations, and we expect to continue to do so in fiscal 2016 and beyond. Furthermore, we believe that a reasonable potential buyerwould offer a control premium for our business that would adequately cover the difference between our stock market capitalization and our book value.Even though we determined that there was no goodwill impairment as of December 31, 2014, the future occurrence of a potential indicator of impairment,such as a significant adverse change in legal factors or business climate, an adverse action or assessment by a regulator, unanticipated competition, a materialnegative change in relationships with significant customers, strategic decisions made in response to economic or competitive conditions, loss of key personnel or amore-likely-than-not expectation that the reporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interimassessment for the reporting unit prior to the next required annual assessment as of December 31, 2015.It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material. Events thatcould, in the future, result in impairment include, but are not limited to, declining sales for a significant product or in a significant geographic region.We also completed our annual indefinite lived asset (NAMIC trademark) impairment test as of December 31, 2014 using the income approach to determinefair value. Under this approach, the relief from royalty method was applied using a 3% long-term growth rate, a 3% royalty rate and a 12% discount rate. Ourassessment of the NAMIC trademark indicated that the carrying value exceeded the fair value by $6.4 million; therefore, the asset was impaired and a $6.4 millionimpairment charge was recorded during the third quarter of 2015. We also re-evaluated the NAMIC trademark at February 28, 2015 and determined that it is nolonger an indefinite-lived intangible. We have assigned it a remaining useful life of 12 years , consistent with customer relationships, and began amortization.64As of May 31, 2015 and 2014 , intangible assets consisted of the following: May 31, 2015 Gross carryingvalue Accumulatedamortization Net carryingvalue Weighted averageuseful life (in thousands) (years)Product technologies$148,776 $(41,447) $107,329 10.2Customer relationships86,371 (42,813) 43,558 12.0Trademarks28,545 (3,229) 25,316 10.7In process R&D Acquired3,600 — 3,600 IndefiniteLicenses7,913 (5,910) 2,003 8.3Distributor relationships900 (900) — 3.0 $276,105 $(94,299) $181,806 May 31, 2014 Gross carryingvalue Accumulatedamortization Net carryingvalue Weighted avguseful life (in thousands) (years)Product technologies$150,298 $(32,930) $117,368 10.2Customer relationships86,645 (37,848) 48,797 11.9Trademark—NAMIC28,600 — 28,600 IndefiniteIn process R&D Acquired3,600 — 3,600 IndefiniteLicenses7,639 (5,211) 2,428 8.4Trademarks6,345 (1,882) 4,463 8.0Distributor relationships900 (900) — 3.0 $284,027 $(78,771) $205,256 Amortization expense was $17.9 million , $16.6 million and $16.6 million for fiscal 2015 , 2014 and 2013 , respectively.Annual amortization of these intangible assets is expected to approximate the following amounts for each of the next five fiscal years (in thousands): 2016$18,4522017$18,5682018$19,3882019$21,4992020$22,74165Adjustments to goodwill for the fiscal year ended May 31, 2015 and May 31, 2014 are as follows (in thousands): TotalBalance, May 31, 2013$355,637Acquisition of Clinical Devices B.V.4,836Balance, May 31, 2014$360,473Tax basis adjustment779Balance, May 31, 2015$361,252During fiscal 2015, goodwill and deferred tax liabilities were adjusted by $0.8 million due to the receipt of a New York State tax grant that was not correctlyaccounted for as part of purchase accounting in fiscal 2012. The Company has determined that this adjustment was not material to any current or prior annual orinterim periods. During fiscal 2014, the change in the carrying value of goodwill is the result of the acquisition of Clinical Devices, B.V. (See Note B.) During thefourth quarter of fiscal 2014, there was an adjustment of $0.5 million to the carrying value of such goodwill related to working capital.NOTE I-INCOME TAXESThe components of income (loss) before income tax provision for the years ended May 31 are as follows: 2015 2014 2013 (in thousands)(Loss) income before tax provision: US$(8,833) $5,199 $(3,614)Non-US834 541 2,027 $(7,999) $5,740 $(1,587) Income tax (benefit) provision analyzed by category and by statement of operations classification for the years ended May 31 is summarized as follows: 2015 2014 2013 (in thousands)Current Federal$(242) $(133) $(1,622)State and local205 99 (52)Non U.S.417 157 468 380 123 (1,206)Deferred(5,111) 2,951 830Income tax (benefit) provision$(4,731) $3,074 $(376)The significant components of deferred income tax (benefit) expense from operations for the years ended May 31 consist of the following: 2015 2014 2013 (in thousands)Deferred tax benefit$(1,916) $1,778 $830Impact of NYS tax reform legislation— 1,173 —Net operating loss carryforward(3,195) — — $(5,111) $2,951 $83066Temporary differences that give rise to deferred tax assets and liabilities are summarized as follows: May 31, 2015 May 31, 2014 (in thousands)Deferred tax assets Net operating loss carryforward$51,785 $48,749Stock-based compensation4,468 4,851Federal and state R&D tax credit carryforward1,646 1,249Inventories2,808 875Expenses incurred not currently deductible2,107 1,379Accrued liabilities114 154Gross deferred tax asset62,928 57,257Deferred tax liabilities Excess tax over book depreciation and amortization42,988 41,843 42,988 41,843Valuation Allowance(1,791) (1,532)Net deferred tax asset$18,149 $13,882At May 31, 2015, we had approximately $173.7 million of remaining Federal net operating loss carryforwards and $34.8 million of state net operating losscarryforwards (“NOL”). Approximately $161.5 million of our Federal net operating loss was generated by acquired companies and are subject to Internal RevenueCode (“IRC”) Section 382 limitations which are expected to limit our ability to utilize these net operating losses on an annual basis. As a result of our IRCSection 382 analyses, it is estimated that approximately $26.1 million of remaining Federal net operating losses and $5.4 million of state net operating losses willexpire prior to utilization. The gross deferred income tax asset (“DTA”) related to the NOL reflects these limitations.Our Federal net operating loss carryforwards as of May 31, 2015 after considering IRC Section 382 limitations are $147.6 million . The expiration of theFederal net operating loss carryforwards are as follows: $30.7 million between 2017 and 2026 and $116.9 million between 2027 and 2033.Our state net operating loss carryforwards as of May 31, 2015 after considering remaining IRC Section 382 limitations are $29.4 million which expire invarious years from 2015 to 2033.As a result of certain realization requirements of ASC 718, the table of deferred tax assets and liabilities shown above does not include certain deferred taxassets as of May 31, 2015 and 2014 that arose directly from tax deductions related to equity compensation greater than compensation recognized for financialreporting. Equity will be increased by $0.3 million if and when such excess tax benefits are ultimately realized.At May 31, 2015, we had a net deferred income tax asset of $18.1 million , after recording a valuation allowance of $1.8 million . The valuation allowanceincreased by $0.3 million in 2015 and increased by $0.8 million in 2014. The 2015 change principally relates to the true-up of our fiscal 2014 tax filings andmanagement’s reevaluation of the expected utilization of state net operating losses based on revised projections of taxable income. The 2014 change relates to thetrue-up of our fully reserved capital losses and state tax credits and net operating losses from our fiscal 2013 tax filings. The valuation allowance recorded againstthe deferred tax assets relates to state tax credits and state NOLs that management has estimated will more likely than not expire before they are expected to beutilized.The Company’s analysis of the need for a valuation allowance considered that the Company has incurred a cumulative loss in the U.S. over the three yearperiod ended May 31, 2015. A majority of the cumulative loss has been caused by the charges associated with the product recall and discontinuance and theimpairment of fixed and intangible assets recorded in the quarter end February 28, 2015, as well as restructuring and integration expenses in the period since theacquisition of Navilyst Medical in May 2012. We anticipate a return to profitability in fiscal 2016. Consideration has also been given to our history of not67having Federal tax loss carryforwards expire unused, as well as the period over which the net deferred tax assets can be realized, including the expiration of ourloss carryforwards and IRC Section 382 limitations.Based on our assessment, it is more likely than not that our U.S. net deferred tax asset will be realized through future taxable earnings, the reversal of existingtaxable temporary differences, and tax planning strategies. Accordingly no valuation allowance has been recorded on this net asset. We will continue to assess theneed for a valuation allowance in the future.If future results are less than projected in the U.S. and if tax planning alternatives do not offset those effects, a valuation allowance may be required to reducethe deferred tax asset, which could have a material impact on our results of operations in the period in which it is recorded. While the net deferred tax asset at May31, 2015 is $19.3 million , if the Company were required to record a valuation allowance it could be $15.3 million greater than this amount due to deferred taxliabilities related to intangibles that have an indefinite reversal period.Our consolidated income tax provision has differed from the amount that would be provided by applying the U.S. Federal statutory income tax rate to ourincome before income taxes for the following reasons: 2015 2014 2013 (in thousands)Income tax (benefit) provision at statutory tax rate of 35%$(2,800) $2,008 $(555)Effect of graduated tax rates80 (57) (16)State income taxes, net of Federal tax benefit(17) 122 95State income tax credits, net of Federal tax benefit— — (23)Impact of Non US operations133 (27) (228)Research and development tax credit(604) (236) (142)Nondeductible acquisition costs— — 110Nondeductible interest on contingent payments265 540 130Nontaxable gain on revaluation of contingent consideration liability(3,138) (1,698) —Tax law changes(454) 1,173 —Effect of elimination of stock compensation APIC pool1,253 440 —Nondeductible stock-based compensation— 176 108Other nondeductible expenses498 384 336Over (under) accrual of prior year Federal and state taxes38 249 (10)Fully reserved capital losses— — (179)Other15 — (2)Income tax (benefit) expense$(4,731) $3,074 $(376)There were no uncertain tax positions as of May 31, 2015, 2014 and 2013.We recognize interest and penalties related to unrecognized tax benefits within our global operations as a component of income tax expense. There were noaccrued interest and penalties recognized in the consolidated balance sheet as of May 31, 2015 and May 31, 2014.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 2011 through 2015 remain open to examination by the various tax authorities. New York State is currently auditing AngioDynamic's franchisetax filings for 2011 through 2013, and we do not anticipate any material adjustments will result. We analyzed filing positions in all of the Federal and statejurisdictions where we are required to file income taxes, as well as all open tax years in these jurisdictions and believe that our income tax filing positions anddeductions will be sustained68on audit and we do not anticipate any adjustments will result in a material adverse effect on our financial condition, results of operations or cash flows.We do 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 $4 million , and are intended to remain indefinitelyinvested in foreign operations. Accordingly, no taxes have been provided on these earnings at May 31, 2015. If these earnings were distributed, the Companywould be subject to both foreign withholding taxes and U.S. income taxes that may not be fully offset by foreign tax credits. A reasonable estimate of the deferredtax liability on these earnings is not practicable at this time.NOTE J—ACCRUED LIABILITIESAs of May 31, 2015 and 2014 , accrued liabilities consist of the following: May 31,2015 May 31,2014 (in thousands)Payroll and related expenses$10,330 $8,114Royalties2,237 2,620Accrued severance158 765Sales and franchise taxes489 1,327Interest rate swap liability257 555Outside services1,522 983Deferred Rent808 154Other2,530 2,733Total$18,331 $17,251NOTE K—LONG-TERM DEBTOn September 19, 2013, we entered into a Credit Agreement (the " Credit Agreement ") with the lenders party thereto, JPMorgan Chase Bank, N.A., asadministrative agent, Bank of America, N.A. and Keybank National Association as co-syndication agents, and J.P. Morgan Securities LLC, Merrill Lynch, Pierce,Fenner & Smith Incorporated and Keybank National Association as joint bookrunners and joint lead arrangers.The Credit Agreement provides for a $100 million senior secured term loan facility (the " Term Loan ") and a $100 million senior secured revolving creditfacility, which includes up to a $20 million sublimit for letters of credit and a $5 million sublimit for swingline loans (the " Revolving Facility ", and together withthe Term Loan, the " Facilities ").The proceeds of the Revolving Facility may be used for general corporate purposes of AngioDynamics and its subsidiaries. The Facilities have a five yearsmaturity. The Term Loan has a quarterly repayment schedule equal to 5% , 5% , 10% , 15% and 65% of its principal amount in years one through five. Interest onboth the Term Loan and Revolving Facility will be based on a base rate or Eurodollar rate plus an applicable margin which increases as our total leverage ratioincreases, with the base rate and Eurodollar rate having ranges of 0.5% to 1.25% and 1.5% to 2.25% respectively. After default, the interest rate may be increasedby 2.0% . The Revolving Facility will also carry a commitment fee of 0.2% to 0.35% per annum on the unused portion.Our obligations under the Facilities are unconditionally guaranteed, jointly and severally, by our material direct and indirect domestic subsidiaries (the "Guarantors "). All obligations of AngioDynamics and the Guarantors under the Facilities are collateralized by first priority security interests in substantially all ofthe assets of AngioDynamics and the Guarantors.We have entered in an interest rate swap agreement, (the "Swap Agreement"), with an initial notional amount of $100 million , to limit the effect of rising ofinterest rates. The Swap Agreement, which qualified for hedge accounting under authoritative guidance, was a contract to exchange floating interest rate paymentsfor fixed interest rate payments of 3.26% on the outstanding balance of the loan over the life of the agreement without the exchange of the underlying notionalamounts. The69Swap Agreement provides for a fixed rate of 0.74% above the applicable rate provided for in the Credit Agreement. The SWAP matures during 2016.On September 19, 2013, we borrowed $100 million under the Term Facility and approximately $41.4 million un der the Revolving Facility to repay the PriorCredit Agreement. As of May 31, 2015 , $91.3 million and $46.4 million were outstanding under the Term Facility and Revolving Facility, respectively. TheCredit Agreement includes customary representations, warranties and covenants, and acceleration, indemnity and events of default provisions, including, amongother things, two financial covenants. The first financial covenant requires us to maintain, as of the end of each of our fiscal quarters, a ratio of (i) consolidatedEBITDA minus consolidated capital expenditures to (ii) consolidated interest expense paid or payable in cash plus scheduled principal payments in respect ofindebtedness under the Credit Agreement of not less than 1.35 to 1.00 . The second financial covenant requires us to maintain, as of the end of each of our fiscalquarters, a ratio of consolidated total indebtedness to consolidated EBITDA of not greater than 3.75 to 1.00 . We were in compliance with both financial covenantsas of May 31, 2015 . As of May 31, 2015 , future minimum principal payments on long-term debt were as follows (in thousands): 2016$8,750201713,750201826,250201988,9102020— $137,660NOTE L—RETIREMENT PLANSWe have a 401(k) plan under which eligible employees can defer a portion of their compensation, part of which is matched by us. Matching contributionswere $3.7 million , $2.8 million and $2.5 million in 2015, 2014 and 2013, respectively. There are also various immaterial foreign retirement plans.NOTE M—STOCKHOLDERS’ EQUITY1. CapitalizationOn October 29, 2014, our Board of Directors approved our Amended and Restated Certificate of Incorporation (the “Amended Certificate”). Under theAmended Certificate, the authorized capital stock is 80,000,000 shares, consisting of 75,000,000 shares of common stock, par value $.01 per share and 5,000,000shares of preferred stock, par value $.01 per share.The holders of common stock are entitled to one vote for each share held. Subject to preferences applicable to any outstanding shares of preferred stock, theholders 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 for dividendpayments. If we liquidate, dissolve, or wind up, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities andliquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no pre-emptive rights or rights to convert their common stockinto any other securities. There are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holdersof common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate in thefuture.Our board of directors has the authority to (i) issue the undesignated preferred stock in one or more series, (ii) determine the powers, preferences and rightsand the qualifications, limitations or restrictions granted to or imposed upon any wholly un-issued series of undesignated preferred stock and (iii) fix the number ofshares constituting any series and the designation of the series, without any further vote or action by our stockholders.70Share Repurchase ProgramOn October 5, 2011, our Board of Directors authorized the repurchase of up to $20 million of our common stock, prior to May 31, 2012. During the fiscalyear ended May 31, 2012, we purchased 142,305 shares at a cost of approximately $2.1 million . There were no shares repurchased under this program duringfiscal 2015, 2014 or 2013.2. Stock Options1997 Stock Option PlanIn 1997, we adopted a Stock Option Plan (the “1997 Plan”). The 1997 Plan provided for the grant to key employees of both nonqualified stock options andincentive stock options and to members of the Board of Directors and consultants of nonqualified stock options. A total of 1,497,674 shares of our common stockwere available to be issued under the 1997 Plan pursuant to the exercise of options. All stock options were to have an exercise price of not less than the fair marketvalue of the shares on the date of grant. Options are exercisable over a period of time to be designated by the administrators of the 1997 Plan (but not more than 10years from the date of grant) and are subject to such other terms and conditions as the administrators may determine. The vesting schedule is subject to thediscretion of our Board of Directors. Options are exercisable immediately upon vesting. In addition, all options, whether vested or not, become exercisable in fullimmediately upon a change of control, as defined under the 1997 Plan. The 1997 Plan terminated in March 2007 and as such, no further options will be grantedunder this plan.2004 Stock and Incentive Award PlanThe 2004 Stock and Incentive Award Plan (the “2004 Plan”) provides for the grant of incentive options to our employees and for the grant of non-statutorystock options, restricted stock, stock appreciation rights, performance units, performance shares and other incentive awards to our employees, directors and otherservice providers. A total of 5,750,000 shares of our 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 committee determinesvesting terms and the exercise price of options granted under the 2004 Plan, but for all incentive stock options the exercise price must at least be equal to the fairmarket value of our common stock on the date of grant. The term of an incentive stock option may not exceed ten years . During the year ended May 31, 2015 anadditional 1,000,000 shares of our common stock have been reserved for issuance under the 2004 plan.On October 5, 2011, we amended the 2004 Stock and Incentive Award Plan to increase the maximum number of shares of our common stock with respect towhich stock options may be granted during any calendar year to one employee from 200,000 shares to 500,000 shares. The following table summarizes information about stock options activity for the fiscal year ended May 31, 2015. 2015 Shares Weighted-averageexerciseprice Weightedaverageremainingcontractuallife Aggregateintrinsicvalue (inthousands)Outstanding at beginning of year2,673,751 $14.82 Granted561,883 $16.14 Exercised(423,804) $13.87 Forfeited(261,738) $14.71 Expired(250,779) $17.98 Outstanding at end of year2,299,313 $14.86 3.89 $4,571Options exercisable at year-end1,271,028 $15.10 2.58 $2,547Options expected to vest in future periods903,143 $14.56 5.52 $1,77871As of May 31, 2015, there remained approximately 2.3 million shares available for granting of options under the 2004 Plan.

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 to May 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 grant date.We measure the fair value of each stock option grant at the date of grant using a Black-Scholes option pricing model. The weighted average grant-date fairvalue of options granted during the years ended 2015, 2014 and 2013 was $4.74 , $4.10 , and $4.19 , respectively. The following assumptions were used in arrivingat the fair value of options granted during 2015, 2014 and 2013, respectively: risk-free interest rates of 1.54% , 1.44% and 0.62% ; expected volatility of 31% ,34% , and 44% ; and expected lives of 4.76 years , 4.74 years , and 4.62 years . We do not declare dividends therefore a dividend yield of zero was used for theyears ended 2015, 2014 and 2013. Risk-free interest rates reflect the yield on zero-coupon U.S. Treasury bonds whose maturity period equals the expected term ofthe option. Expected volatilities are based on the historical volatility of our stock. The expected option lives are based on our historical experience of employeeexercise behavior.The total intrinsic value of options exercised during the years ended 2015, 2014 and 2013 amounted to $1.6 million , $1.0 million , and $0.1 million ,respectively. As of May 31, 2015, there was $3.5 million of total unrecognized compensation cost related to non-vested options. The cost is expected to berecognized over a weighted average period of 3 years .Cash received from option exercises during 2015, 2014 and 2013 was $4.3 million , $1.3 million and $0.1 million , respectively. The tax benefit realizedfrom stock options exercised during the years ended 2015 and 2014 was $0.5 million and $0.1 million , respectively. There was no tax benefit realized from stockoption exercises during the year ended 2013.3. Performance Share and Restricted Stock Unit AwardsWe grant restricted stock units to certain employees under the 2004 Plan which give the recipients the right to receive shares of our stock upon vesting. Therestricted stock unit awards vest in equal annual installments over the term of the grants. Unvested restricted stock unit awards will be forfeited if the recipientceases to be employed by us, competes with our business or otherwise engages in activities detrimental to our business before such date. The following table summarizes information about restricted stock unit activity for the year ended May 31, 2015.72 Non-Vested StockAward Units Weighted AverageGrant-Date Fair ValueNon-vested at beginning of year587,991 $14.82Granted242,158 $14.75Vested(160,207) $14.83Canceled(106,841) $12.33Non-vested at end of year563,101 $13.73Awards expected to vest in future periods492,432 $13.73The fair value of each restricted stock unit is the market price of our stock on the date of grant. The weighted average grant date fair value of restricted stockunits granted during the years ended 2015, 2014 and 2013 was $14.75 , $13.23 and $10.79 , respectively. The total intrinsic value of restricted stock units vestingduring the years ended 2015, 2014 and 2013 was $2.4 million , $1.8 million , and $1.2 million , respectively. As of May 31, 2015, there was $5.6 million of totalunrecognized compensation cost related to non-vested restricted stock awards. The cost is expected to be recognized over a weighted average period of 2 years.We grant performance share awards to certain employees under the 2004 Plan which gives the recipients the right to receive shares of our stock if certaincriteria is met. The performance criteria is established by the compensation committee for vesting of the performance share awards and may include factors such asthe achievement of certain sales, operating income and earnings per share (“EPS”) goals. Performance share awards are subject to additional conditions, includingthe recipient’s continued employment with us.Performance share units are valued using a Monte Carlo simulation model on the date of grant. As of May 31, 2015 and 2014, the weighted average grantdate fair market value for new grants was $19.83 and $25.56 , respectively. Compensation cost is recognized over the performance period when the metrics areprobable of being achieved which is typically three years. As of May 31, 2015, 0.2 million performance share units with a weighted average remaining contractualterm of 3 years and $2.2 million of unrecognized compensation cost were outstanding. As of May 31, 2014, 0.1 million performance share units with a weightedaverage remaining contractual term of 3 years and $1.8 million of unrecognized compensation cost were outstanding.4. Employee Stock Purchase PlanThe Employee Stock Purchase Plan (the “Stock Purchase Plan”) provides a means by which our employees (the “participants”) are given an opportunity topurchase our common stock through payroll deductions. On October 29, 2014, our Board of Directors, approved our Amended and Restated Certificate ofIncorporation (the “Amended Certificate”). Under the Amended Certificate, the maximum number of shares to be offered under the Stock Purchase Plan is2,000,000 shares of our common stock, subject to any increase authorized by the Board of Directors. Shares are offered through two purchase periods, each withduration of approximately 6 months , commencing on the first business day of the first and third fiscal quarters. An employee is eligible to participate in anoffering period if, on the first day of an offering period, he or she has been employed in a full-time capacity for at least six months , with a customary workingschedule of 20 or more hours per week and more than five months in a calendar year . Employees who own stock possessing 5% or more of the total combinedvoting power or value of all classes of our stock are not eligible to participate in the Stock Purchase Plan. The purchase price of the shares of common stockacquired on each purchase date will be the lower of (i) 85% of the fair 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 last day of the purchase period, subject to adjustments made by the Board of Directors. The StockPurchase Plan is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code. During the year endedMay 31, 2015, an additional 800,000 shares of our common stock have been reserved for issuance under the Stock Purchase Plan. We use the Black-Scholes option-pricing model to calculate the purchase date fair value of the shares issued under the Stock Purchase Plan and recognizeexpense related to shares purchased ratably over the offering period. During the years ended 2015, 2014 and 2013, 119,001 , 146,275 and 123,556 shares,respectively, were issued at an average price of $11.89 , $9.30 and $9.80 , respectively, under the Stock Purchase Plan. As of May 31, 2015, 1.1 million sharesremained available for future purchases under the Stock Purchase Plan.735. Other itemsShare-based compensation expense recognized in the consolidated statement of operations during the years ended 2015, 2014 and 2013 amounted to $6.0million , $5.5 million and $4.6 million , respectively. The income tax benefit recognized in earnings on the compensation expense recognized for all share-basedcompensation arrangements amounted to $2.0 million , $1.8 million and $1.5 million , respectively. Income tax expense of $1.3 million and $0.5 million wasrecorded in continuing operations for the excess of cumulative book deductions over actual tax deductions for the years ended 2015 and 2014, respectively.Additional income tax expense of $0.1 million for 2014 and $1.6 million for 2013 was recorded in shareholder’s equity for the excess book deductions to the extentprior tax deductions exceeded prior book deductions. NOTE N—EARNINGS PER SHAREBasic earnings per share are based on the weighted average number of common shares outstanding without consideration of potential common stock. Inaddition, diluted earnings per share include the dilutive effect of potential common stock consisting of stock options, restricted stock units and performance stockunits, provided that the inclusion of such securities is not anti-dilutive. In periods with a net loss, stock options and restricted stock units are not included in thecomputation of basic loss per share as the impact would be anti-dilutive.The following table reconciles basic to diluted weighted average shares outstanding for the years ended May 31, 2015 , 2014 and 2013 : 2015 2014 2013Basic35,683,139 35,135,689 34,817,279Effect of dilutive securities— 304,161 —Diluted35,683,139 35,439,850 34,817,279 Securities excluded as their inclusion would be anti-dilutive2,862,414 2,347,426 2,904,944NOTE O—COMMITMENTS AND CONTINGENCIESLeasesWe are committed under non-cancelable operating leases for facilities and equipment.

In this action, we sought judgment against biolitec for defense and74indemnification in two lawsuits which we previously settled. Our claims arise out of a Supply and Distribution Agreement (“SDA”) entered into with biolitec onApril 1, 2002. On September 27, 2011, the U.S. District Court granted key portions of our motion for summary judgment in our legal case against biolitec. TheCourt also dismissed biolitec’s counterclaims against us. The court denied one portion of our summary judgment motion, which sought to recover additional costsfrom biolitec, leaving this for adjudication at trial. On November 8, 2012, the Court granted partial judgment to us in the amount of $23.2 million. Biolitecappealed this judgment. On August 23, 2013, the U.S. Court of Appeals for the Second Circuit dismissed biolitec’s appeal.In October 2009, we commenced an action in the United States District Court for the District of Massachusetts entitled AngioDynamics, Inc. v.biolitec AG and Wolfgang Neuberger. The Complaint in this action was amended in March 2010. This action seeks to recover against biolitec, Inc.’s parent entitiesand CEO for tortiously interfering with biolitec, Inc.’s contractual obligation to defend and indemnify us, and also seeks to pierce the corporate veil of biolitec, Inc.and to invalidate certain alleged fraudulent transfers in order to hold biolitec, Inc.’s parent entities jointly and severally liable for the alleged breach of the SDA. OnSeptember 13, 2012, the Massachusetts Court granted our request for a preliminary injunction prohibiting the downstream merger of biolitec AG with its Austriansubsidiary. On April 1, 2013, the U.S. Court of Appeals for the First Circuit affirmed the preliminary injunction. On January 14, 2014, the District Court enteredjudgment in our favor as to liability. On March 18, 2014, the District Court entered judgment in our favor against Biolitec AG, Biomed Technology Holdings, Ltd.,and Wolfgang Neuberger, jointly and severally, in the amount of $74.9 million. The defendants have appealed this judgment.August 29, 2013, we became co-plaintiffs in an adversary proceeding in the United States Bankruptcy Court for the District of New Jersey entitledCyganowski, Trustee, et al. v. Biolitec U.S., Inc., et al. In this action, we assert claims of conversion, unjust enrichment, tortious interference, and unfaircompetition against various biolitec entities for alleged violation of Bankruptcy Court settlement and sale orders under which we acquired certain assets ofBiolitec, Inc. On September 3, 2013, we, along with our co-plaintiff, obtained a temporary restraining order against the defendants in this action. On January 22,2015, the Bankruptcy Court entered a permanent injunction on our behalf for an additional two years.C.R. Bard, Inc. v. AngioDynamics, Inc.On January 11, 2012, C.R. Bard, Inc. filed a suit in the United States District Court of Utah claiming certain of our implantable port products infringeon 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-trialconsolidation with separate actions it filed on the same day against Medical Components, Inc. and Smiths Medical ASD, Inc., but had asked for supplementalbriefing on the issue of whether to conduct a common Markman hearing. Meanwhile, we filed petitions for reexamination in the US Patent and Trademark Office("PTO") which seek to invalidate all 3 patents asserted in the litigation. Our petitions have been granted and 40 of 41 patent claims have been and remain rejected.The Patent Office has issued a Final Rejection of all the claims subject to reexamination and Bard has filed appeals. The parties have completed briefing on theappeals and oral argument was held on June 18, 2015. The parties are awaiting decision by the Board of Appeals and Interferences. The case has been stayedpending final resolution of the PTO process. The Company believes these claims are without merit and intends to defend them vigorously. The Company has notrecorded an expense related to the outcome of this litigation because it is not 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. filed suit in the United States District Court for the District of Delawareclaiming certain of the Company’s implantable port products infringe three Bard patents (the “Delaware Action). Bard is seeking unspecified damages and otherrelief; and the patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1,2015, the Company filed two motions inresponse to Bard’s Complaint - - one seeks transfer to the District of Utah where the Utah Action is currently pending, and the other seeks dismissal of the entirecomplaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statute and in lightof recent authority from the U. S. Supreme Court. Briefing is complete on both motions (except Bard has requested permission to file a Sur-Reply on the dismissalmotion) and the parties are awaiting decision by the Delaware Court. The Company believes these claims are without merit and intends to defend them vigorously.The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable norreasonably estimable. 75Governmental InvestigationsLC BeadsIn June 2014 we received a subpoena from the U . S . Department of Justice (the “DOJ”) requesting documents in relation to a purported criminalinvestigation 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 cooperating fully withthis investigation and at this time are unable to predict its scope, duration or outcome.EVLTIn April 2015 we received a subpoena from the DOJ requesting documents in relation to a criminal investigation the DOJ is conducting regardingpurported marketing and sale of certain of AngioDynamics’ VenaCure EVLT products for the treatment of certain indications that had not been approved by theFDA. We are cooperating fully with this investigation and at this time are unable to predict its scope, duration or outcome.Future Purchase ObligationsWe have entered into commitments for future minimum inventory purchases related to several core products. Total future non-cancelable purchaseobligations through fiscal 2018 amount to $9.9 million .

The initiative is expected to create greater efficiencies and drive business performance improvements by focusing on several key elements,including product rationalization, lean manufacturing initiatives, supply chain optimization and enterprise resource planning (ERP) implementation. The plan alsoincorporates the consolidation of our New York plants to establish a single manufacturing center in Glens Falls and a distribution center in Queensbury. During thecourse of the three-year program, it is expected that we will reduce our New York employee base by approximately 80-100 positions as a result of this plantconsolidation and reorganization. Over the three year period, we expect to invest $5.4 million in facility improvements. In addition, total restructuring charges areestimated to be $4.7 million . During the year end May 31, 2015 , the cost incurred was $2.0 million , consisting of $1.5 million of accelerated depreciation and$0.5 million of severance and related costs. During the year ended May 31, 2014 , the cost incurred was $1.4 million , consisting of $0.6 million of severance andrelated costs, $0.7 million of accelerated depreciation and $0.1 million in other costs. These costs are included in “Acquisition, restructuring and other items, net”in the statements of income.During the year ended May 31, 2015 , we initiated a restructuring of finance, R&D and S&M organizations to improve our profitability. As part of therestructuring, we recorded $0.8 million in severance expense which is included in "Acquisition, restructuring and other items, net" in the statement of operations.NOTE R—QUARTERLY INFORMATION (unaudited)Quarterly results of operations during the fiscal years ended May 31, 2015 and 2014 are as follows: 2015 Firstquarter Secondquarter Thirdquarter Fourthquarter (in thousands, except per share data)Net sales$87,331 $92,149 $86,597 $90,897Gross profit45,825 47,656 37,851 45,557Net income (loss)470 1,338 (4,262) (814)Earnings (loss) per common share Basic0.01 0.04 (0.12) (0.02)Diluted0.01 0.04 (0.12) (0.02) 77 2014 Firstquarter Secondquarter Thirdquarter Fourthquarter (in thousands, except per share data)Net sales$83,644 $88,571 $88,150 $94,060Gross profit42,580 44,885 44,793 47,410Net income (loss)(373) (261) 4,515 (1,215)Earnings (loss) per common share Basic(0.01) (0.01) 0.13 (0.03)Diluted(0.01) (0.01) 0.13 (0.03)The data in the schedules above has been intentionally rounded to the nearest thousand and therefore the quarterly amounts may not sum to the full yearamounts.During the quarter ended February 28, 2015, the Company recorded aggregate out of period corrections of $0.4 million, net of tax, which negativelyimpacted net income (loss) in the period.

TrowbridgeName: Stephen A. TrowbridgeTitle: Senior Vice President and General Counsel Exhibit 10.1.5Total Shareholder Return Performance Unit Award Program (the “Program”)Performance Period July 22, 2015 – July, 2018I. Purpose of the ProgramThe purpose of the Program is to align AngioDynamics’ executive compensation program with the interests of shareholders and toreinforce the concept of pay for performance by comparing the relative Total Shareholder Return (“TSR”) of shares ofAngioDynamics’ Common Stock (the “Common Stock”) to the TSR of a pre-defined peer group (the “Peer Group”) of companiesover a three-year period beginning on July 22, 2015.The Program entails the grant of Performance Unit Awards, and the program shall be administered under the AngioDynamics 2004Stock and Incentive Award Plan, as amended (the “Plan”). Terms not defined in this Program document but defined in the Plan shallhave the meaning ascribed to such term in the Plan. The Program is established under section 5.II of the Plan and is intended toqualify for the performance-based compensation exception under Section 162(m) of the Internal Revenue Code (“Code”).II. Eligible ParticipantsThe Program covers members of the Executive Management Team (“EMT”) on the date that awards are granted under the Programas determined and in the amounts established by the Board of Directors (the “Board”).The Board may review Program eligibility criteria for Participants in the Program from time to time and may revise such criteria atany time, even within a Program year, with or without notice and within its sole discretion.III.Performance Share UnitsPursuant to the Plan and this Program, the Board may, in its sole discretion, grant Performance Unit Awards to members of the EMT(the “Grant Date”). Each Performance Unit Award shall specify a target number of shares of Common Stock underlying thePerformance Unit Award (the “Target Amount”). Shares of Common Stock underlying the Performance Unit Award granted underthe Program (the “Performance Unit Awards”) shall be issued only upon satisfaction of both the performance vesting criteriadescribed in this Section III and the payment eligibility criteria described in Section VII. The applicable performance criteria arebased on the TSR of AngioDynamics’ Common Stock relative to the TSR of the common stock of the companies in the Peer Group.1The TSR for AngioDynamics and all other companies in the Peer Group will be measured over a three-year period beginning on July22, 2015 and ending on the day that is the second trading day following AngioDynamics’ annual earnings announcement for itsfiscal year ended May 31, 2018 (the “Performance Period”).The number of shares of Common Stock that vest under the Performance Unit Award will be in a range of 0% to 200% of the TargetAmount of shares of Common Stock pursuant to the Performance Unit Award granted to the Participant based uponAngioDynamics’ TSR percentile ranking relative to the Peer Group as follows:TSR PerformancePercentile RankPerformance Share Unitsas a Percent of Target75th Percentile or above200%50th Percentile100%25th Percentile50%Below 25th Percentile0%If the minimum level of performance set forth above is achieved for the Performance Period, the number of shares of Common Stockvesting under the Performance Unit Award will be calculated linearly between each set of data points.Following the end of the Performance Period, the Board shall determine the number of shares of Common Stock, based upon thetotal number of shares of Common Stock underlying the Target amount of the Performance Unit Award, that shall become vestedpursuant to AngioDynamics’ relative TRS percentile rank during the Performance Period pursuant to the table set forth above.The Board shall issue a number of shares of Common Stock underlying the Performance Unit Award to the Participant in accordancewith this Program and the applicable grant agreement equal to the number of shares of Common Stock, if any, that vested in thePerformance Period.The Board’s determination regarding the Company’s performance to the performance criteria with respect to the Performance Periodshall be final and binding.Shares of Common Stock will be delivered or otherwise made available to the Participant as soon as practicable (and in all eventswithin sixty (60) days) after the end of the Performance Period. Any shares of Common Stock underlying a Performance Unit Awardas to which the performance criteria of this Section III have not been satisfied as of the end of the Performance Period will beforfeited in their entirety.2IV. Calculation of Total Shareholder Return and DefinitionsThe TSR for AngioDynamics and each other company in the Peer Group shall include any cash dividends paid during thePerformance Period and shall be determined as follows:Total Shareholder Return for each Performance Cycle =(Change in Stock Price + Dividends Paid) / Beginning Stock Price“ Beginning Stock Price ” with respect to AngioDynamics means the closing price as quoted on the NASDAQ Global SelectMarket of one share of the Company’s Common Stock on the beginning date of the Performance Period. “Beginning Stock Price”with respect to each other company in the Peer Group means the daily average closing price as quoted on the New York StockExchange or the NASDAQ Global Select Market, as applicable, of one (1) share of common stock for the two calendar months priorto the beginning of the Performance Period.“ Change in Stock Price ” means the difference between the Beginning Stock Price and the Ending Stock Price.“ Dividends Paid ” means the total of all cash dividends paid on one (1) share of stock during the Performance Period.“ Ending Stock Price ” with respect to AngioDynamics means the closing price as quoted on the NASDAQ Global Select Market ofone share of the Company’s Common Stock on the ending date of the Performance Period. “Ending Stock Price” with respect toeach other company in the Peer Group means the daily average closing price as quoted on the New York Stock Exchange or theNASDAQ Global Select Market, as applicable, of one (1) share of common stock for the last two calendar months of thePerformance Period.Example: If the Beginning Stock Price for a company was $25.00 per share, and the company paid $2.50 in dividends over thePerformance Period, and the Ending Stock Price was $30.00 per share (thereby making the Change in Stock Price $5.00 ($30.00minus $25.00)), then the TSR for that company would be thirty percent (30%). The calculation is as follows: 0.30 = ($5.00 + $2.50) /$25.003V.Calculation of Percentile PerformanceFollowing the calculation of the TSR for the Performance Period for AngioDynamics and each other company in the Peer Group,AngioDynamics and the other companies in the Peer Group will be ranked, in order of maximum to minimum, according to theirrespective TSR for the Performance Period.After this ranking, the percentile performance of AngioDynamics as compared to the other companies in the Peer Group shall bedetermined by the following formula:“P” represents the percentile performance which will be rounded, if necessary, to the nearest whole percentile by application ofstandard scientific rounding conventions.“N” represents the number of companies in the Peer Group, including AngioDynamics.“R” represents AngioDynamics’ ranking versus the other companies in the Peer Group.Example: If AngioDynamics ranked 10 th out of 56 companies, the performance (“P”) therefore will be in the 84 th percentile.This calculation is as follows: 0.837 = 1 - (10 - 1) / (56 - 1) VI.Peer GroupThe companies in the Peer Group can be found in Appendix A attached hereto.If, during the Performance Period, two companies in the Peer Group merge, the surviving company shall remain in the Peer Group.If, during the Performance Period, a company in the Peer Group merges with, or is acquired by, a company that is not in the PeerGroup, and the company in the Peer Group is the surviving company, then the surviving company shall not be included in the PeerGroup.If, during the Performance Period, a company in the Peer Group merges with, or is acquired by, a company that is not in the PeerGroup, and the company in the Peer Group is not the surviving4company or the surviving company is no longer publicly traded, then the surviving company shall not be included in the Peer Group.If, during the Performance Period, a company in the Peer Group sells all or substantially all of its assets, such company shall not beincluded in the Peer Group.If, during the Performance Period, a company in the Peer Group splits-off or spins-off or consummates any other extraordinaryreorganization transaction, and such spin-off, split-off or reorganization comprises more than 20% of the assets of the company priorto such spin-off, split-off or reorganization, such company shall not be included in the Peer Group.If, during the Performance Period, a company in the Peer Group files for bankruptcy or otherwise ceases to be traded or quoted onany national exchange, such Company shall remain in the Peer Group. If no public stock price information is available for suchcompany after it files for bankruptcy or otherwise ceases to be traded or quoted on a national securities exchange, the TSR for suchcompany shall equal a total loss of equity (or -100%) during the Performance Period for which no stock price information isavailable.The triggering event for determining whether a company shall be excluded from the Peer Group pursuant to this Section VI shall bethe first official announcement of an SEC reportable event.
