BusinessUnless the context requires otherwise, references to “Lantheus,” “the Company,” “our company,” “we,” “us” and “our” refer to Lantheus Holdings,Inc. and, as the context requires, its direct and indirect subsidiaries, references to “Lantheus Holdings” refer to Lantheus Holdings, Inc. and references to“LMI” refer to Lantheus Medical Imaging, Inc., our wholly-owned subsidiary.OverviewWe are a global leader in the development, manufacture and commercialization of innovative diagnostic medical imaging agents and products thatassist clinicians in the diagnosis and treatment of cardiovascular and other diseases. Our agents are routinely used to diagnose coronary artery disease,congestive heart failure, stroke, peripheral vascular disease and other diseases. Clinicians use our imaging agents and products across a range of imagingmodalities, including nuclear imaging, echocardiography and magnetic resonance imaging, or MRI. We believe that the resulting improved diagnosticinformation enables healthcare providers to better detect and characterize, or rule out, disease, potentially achieving improved patient outcomes, reducingpatient risk and limiting overall costs for payers and the entire healthcare system.Our commercial products are used by cardiologists, nuclear physicians, radiologists, internal medicine physicians, sonographers and technologistsworking in a variety of clinical settings. We sell our products to hospitals, clinics, group practices, integrated delivery networks, group purchasingorganizations, radiopharmacies and, in certain circumstances, wholesalers.We sell our products globally and have operations in the United States, Puerto Rico, Canada and Australia and distribution relationships in Europe,Asia Pacific and Latin America.Our ProductsOur portfolio of 10 commercial products is diversified across a range of imaging modalities. Our products include contrast agents and medicalradiopharmaceuticals (including technetium generators). • Contrast agents are typically non-radioactive compounds that are used in diagnostic procedures such as cardiac ultrasounds, or echocardiograms,x-ray imaging or MRI that are used by physicians to improve the clarity of the diagnostic image. • Radiopharmaceuticals are radioactive pharmaceuticals used by clinicians to perform nuclear imaging procedures. • In certain circumstances, a radioactive element, or radioisotope, is attached to a chemical compound to form the radiopharmaceutical.This act of attaching the radioisotope to the chemical compound is called radiolabeling, or labeling. • In other circumstances, a radioisotope can be used as a radiopharmaceutical without attaching any additional chemical compound. • Radioisotopes are most commonly manufactured in a nuclear research reactor, where a radioactive target is bombarded with subatomicparticles, or on a cyclotron, which is a type of particle accelerator that also creates radioisotopes. • Two common forms of nuclear imaging procedures are single-photon emission computed tomography, or SPECT, which measures gammarays emitted by a SPECT radiopharmaceutical, and positron emission tomography, or PET, which measures positrons emitted by a PETradiopharmaceutical.As an example of the procedures in which our products may be used, in the diagnosis of coronary artery disease, a typical diagnostic progression couldinclude an electrocardiogram, followed by an echocardiogram 3 Table of Contents(possibly using our agent DEFINITY), and then a nuclear myocardial perfusion imaging, or MPI, study using either SPECT or PET imaging (possibly usingour technetium generator or one of our MPI agents). An MPI study assesses blood flow distribution to the heart. MPI is also used for diagnosing the presenceof coronary artery disease.DEFINITYDEFINITY is the leading ultrasound contrast imaging agent based on revenue and usage and, in the United States, is indicated for use in patients withsuboptimal echocardiograms. Numerous patient conditions can decrease the quality of images of the left ventricle, the primary pumping chamber of the heart.Of the total number of echocardiograms performed each year in the United States—over 31 million in 2015—a third party source estimates thatapproximately 20%, or approximately 6 million echocardiograms in 2015, produce suboptimal images. The use of DEFINITY during echocardiographyallows physicians to significantly improve their assessment of the function of the left ventricle.DEFINITY is a clear, colorless, sterile liquid, which, upon activation in the Vialmix apparatus, a medical device specifically designed for DEFINITY,becomes a homogenous, opaque, milky white injectable suspension of perflutren-containing lipid microspheres. After activation and intravenous injection,DEFINITY improves the ultrasound delineation of the left ventricular endocardial border, or innermost layer of tissue that lines the chamber of the leftventricle. Better visualization of the ventricle wall allows clinicians to see wall motion abnormalities, namely that the heart muscle is not expanding andcontracting in a normal, consistent and predictable way. We believe this allows clinicians to make more informed decisions about disease status.DEFINITY offers flexible dosing and administration through an IV bolus injection or continuous IV infusion. We believe DEFINITY’s synthetic lipid-cased coating gives the compound a distinct competitive advantage, because it provides a strong ultrasound signal and is the only perflutren-based echocontrast agent made without albumin. As a result, we believe DEFINITY will be a key driver of the future growth of our business, both in the United Statesand in international markets as we continue to grow contrast penetration through sales and marketing efforts focused on the appropriate use of contrast andmaintain our leading position.Since its launch in 2001, DEFINITY has been used in imaging procedures in more than 6.7 million patients throughout the world. In 2015, DEFINITYwas the leading ultrasound imaging agent based on revenue and usage, used by echocardiologists and sonographers. We estimate that DEFINITY hadapproximately 78% share of the market for contrast agents in echocardiography procedures in the United States as of December 2015. DEFINITY currentlycompetes with Optison, a GE Healthcare product, Lumason, a recently-approved Bracco product (known as SonoVue outside the U.S.) as well as other non-echocardiography imaging modalities. DEFINITY, Optison and Lumason all carry an FDA-required boxed warning, which has been modified over time, tonotify physicians and patients about potentially serious safety concerns or risks posed by the products. See “Risk Factors—Risks Relating to our Businessand Industry—Ultrasound contrast agents may cause side effects which could limit our ability to sell DEFINITY.”DEFINITY is currently patent protected in the United States until 2021 and in numerous foreign jurisdictions with patent or regulatory protection until2019, and we have an active life cycle management program for this agent. DEFINITY generated revenues of $111.9 million, $95.8 million and $78.1 millionfor the years ended December 31, 2015, 2014 and 2013, respectively. DEFINITY represented approximately 38%, 32% and 28% of our revenues in 2015,2014 and 2013, respectively. 4 Table of ContentsOur leading commercial radiopharmaceutical products are:TechneLiteTechneLite is a self-contained system or generator of Technetium (Tc99m), a radioactive isotope with a six hour half-life, used by radiopharmacies toprepare various nuclear imaging agents. Technetium results from the radioactive decay of molybdenum-99, or Moly, itself a radioisotope with a 66-hour half-life produced in nuclear research reactors around the world from enriched uranium. The TechneLite generator is a little larger than a coffee can in size, and theself-contained system houses a vertical glass column at its core that contains Moly. During our manufacturing process, Moly is added to the column withinthe generator where it is adsorbed onto alumina powder. The column is sterilized, enclosed in a lead shield and further sealed in a cylindrical plasticcontainer, which is then immediately shipped to our radiopharmacy customers. Because of the short half-lives of Moly and technetium, radiopharmaciestypically purchase TechneLite generators on a weekly basis pursuant to standing orders.The technetium produced by our TechneLite generator is the medical radioisotope that can be attached to a number of imaging agents, including ourown Cardiolite products and Neurolite, during the labeling process. To radiolabel a technetium-based radiopharmaceutical, a vial of sterile saline and avacuum vial are each affixed to the top of a TechneLite generator. The sterile saline is pulled through the generator where it attracts technetium resultingfrom the radioactive decay of Moly within the generator column. The technetium-containing radioactive saline is then pulled into the vacuum vial andsubsequently combined by a radiopharmacist with the applicable imaging agent, and individual patient-specific radiolabeled imaging agent doses are thenprepared. When administered, the imaging agent binds to specific tissues or organs for a period of time, enabling the technetium to illustrate the functionalhealth of the imaged tissues or organs in a diagnostic image. Our ability to produce and market TechneLite is highly dependent on our supply of Moly. See“—Raw Materials and Supply Relationships—Molybdenum-99.”TechneLite is produced in thirteen sizes and is currently marketed primarily in North America and Latin America, largely to radiopharmacies thatprepare unit doses of radiopharmaceutical imaging agents and that ship these preparations directly to hospitals for administration to patients. In the UnitedStates, we have supply contracts with significant radiopharmacy chains, including Cardinal, United Pharmacy Partners, or UPPI, GE Healthcare and TriadIsotopes, Inc., or Triad. We also supply generators on a purchase order basis with other customers. As of December 2015, we believe TechneLite hadapproximately 28% of the U.S. generator market share, competing primarily with technetium-based generators produced by Mallinckrodt Pharmaceuticals, orMallinckrodt. In Puerto Rico, we also supply TechneLite to our Company-owned radiopharmacy to prepare radiopharmaceutical imaging agent unit doses. InCanada, where we sold our radiopharmacies in January 2016, we have a supply agreement with Isologic, the buyer of those radiopharmacies. Under thesupply agreement with Isologic, we will supply Isologic with certain of our products on commercial terms, including certain product purchase commitmentsby Isologic. The agreement expires on January 12, 2021 and may be terminated upon the occurrence of specified events, including a material breach by theother party, bankruptcy by either party and certain force majeure events.The Moly used in our TechneLite generators can be produced using targets made of either highly-enriched uranium, or HEU, or low-enriched uranium,or LEU. LEU consists of uranium that contains less than 20% of the uranium-235 isotope. HEU is often considered weapons grade material, with 20% or moreof uranium-235. On January 2, 2013, President Obama signed into law the American Medical Isotopes Production Act of 2012, or AMIPA, as part of the 2013National Defense Authorization Act. AMIPA encourages the domestic production of LEU Moly and provides for the eventual prohibition of the export ofHEU from the United States. Although Medicare generally does not provide separate payment to hospitals for the use of diagnostic radiopharmaceuticalsadministered in an outpatient setting, since January 1, 2013, the Centers for Medicare and Medicaid Services, or CMS, the federal agency responsible foradministering the Medicare program, has provided an add-on payment under the hospital outpatient prospective payment system for every technetiumdiagnostic dose produced from non-HEU sourced Moly, to cover the marginal cost for radioisotopes produced from non-HEU sources. Our LEU TechneLitegenerator satisfies the reimbursement requirements under the applicable CMS rules. 5 Table of ContentsTechneLite has patent protection in the United States and various foreign countries on certain component technology currently expiring in 2029. Inaddition, given the significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, webelieve we have a substantial amount of valuable and defensible proprietary intellectual property associated with the product. We believe that our substantialcapital investments in our highly automated TechneLite production line and our extensive experience in complying with the stringent regulatoryrequirements for the handling of nuclear materials create significant and sustainable competitive advantages for us in generator manufacturing anddistribution. TechneLite generated revenues of $72.6 million, $93.6 million and $92.2 million for the years ended December 31, 2015, 2014 and 2013,respectively. TechneLite represented approximately 25%, 31% and 33% of our revenues in 2015, 2014 and 2013, respectively.Xenon Xe 133 GasXenon is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also to image cerebral blood flow. Our Xenon ismanufactured by a third party as part of the Moly production process and packaged by us. We are currently the leading provider of Xenon in the UnitedStates. In 2015, 2014 and 2013, Xenon Xe 133 Gas represented approximately 17%, 12% and 11%, respectively, of our revenues.Other Commercial ProductsIn addition to the products listed above, our portfolio of commercial products also includes important imaging agents in specific segments, whichprovide a stable base of recurring revenue. Most of these products have a favorable industry position as a result of our substantial infrastructure investment,our specialized workforce, our technical know-how and our supplier and customer relationships. • Cardiolite, also known by its generic name sestamibi, is an injectable, technetium-labeled imaging agent used in MPI procedures to assess bloodflow to the muscle of the heart using SPECT. Cardiolite was approved by the FDA in 1990 and its market exclusivity expired in July 2008.Included in Cardiolite revenues are branded Cardiolite and generic sestamibi revenues, some of which we produce and some of which we procurefrom third parties from time to time. • Neurolite is an injectable, technetium-labeled imaging agent used with SPECT technology to identify the area within the brain where blood flowhas been blocked or reduced due to stroke. We launched Neurolite in 1995. • Thallium Tl 201 is an injectable radiopharmaceutical imaging agent used in MPI studies to detect coronary artery disease. We have marketedThallium since 1977 and manufacture the agent using cyclotron technology. • Gallium Ga 67 is an injectable radiopharmaceutical imaging agent used to detect certain infections and cancerous tumors, especially lymphoma.We manufacture Gallium using cyclotron technology. • Gludef is an injectable, fluorine-18-radiolabeled imaging agent used with PET technology to identify and characterize tumors in patientsundergoing oncologic diagnostic procedures. Gludef is our branded version of FDG in the United States. • Quadramet, our only therapeutic product, is an injectable radiopharmaceutical used to treat severe bone pain associated with certain kinds ofcancer. Previously, we served as a contract manufacturer of Samarium 153, the radioisotope used to prepare Quadramet. Effective December 13,2013, we purchased the rights to Quadramet in the United States and now serve as the direct manufacturer and supplier of Quadramet in theUnited States. • Ablavar is an injectable, gadolinium-based contrast agent used with magnetic resonance angiography, or MRA, a type of MRI scan, to image theiliac arteries that start at the aorta and go through the pelvis into the legs, in order to diagnose narrowing or blockage of these arteries in knownor suspected peripheral vascular disease. We launched Ablavar in January 2010. 6 Table of ContentsFor revenue and other financial information for our U.S. and International segments, see Note 20, “Segment Information” to our consolidated financialstatements.Distribution, Marketing and SalesThe following table sets forth certain key market information for each of our commercial products: Product Currently Marketed Regulatory Approval,but Not Currently MarketedDEFINITY United States, Canada,Australia, South Korea, New Zealand EU, Israel, India(1), Singapore,MexicoTechneLite United States, Canada,Caribbean Islands, Colombia,Costa Rica, Taiwan South Korea, Mexico, Panama,AustraliaXenon Xe 133 Gas United States, Taiwan CanadaCardiolite United States, Canada, Cost Rica, Israel, Japan,South Korea, Taiwan, Thailand,Australia, New Zealand, Hong Kong, Panama, Philippines Colombia, MexicoNeurolite United States, Canada, Costa Rica, Japan,Hong Kong, Philippines, Australia,New Zealand, Taiwan, Thailand,Europe(2)(3) South Korea, Taiwan, MexicoThallium Tl 201 United States, Canada, Australia,South Korea, Pakistan, Panama, Taiwan New ZealandGallium Ga67 United States, Canada, Colombia, Mexico,Pakistan, Australia, Costa Rica, South Korea,Panama, Taiwan, New Zealand NoneFDG Puerto Rico NoneQuadramet United States NoneAblavar United States, Canada Australia (1)JHS is pending approval in India.(2)JHS has regulatory approval for Neurolite in Austria, Belgium, Denmark, Finland, France, Germany, Italy, Luxembourg, Norway, Slovenia, Spain andSweden.(3)JHS has regulatory approval pending for Neurolite in Czech Repbulic.In the United States and Canada, we sell DEFINITY through our sales team of approximately 80 employees that call on healthcare providers in theechocardiography space, as well as group purchasing organizations and integrated delivery networks. In 2013, we transitioned the sales and marketing effortsfor Ablavar from our sales team to our customer service team in order to allow our sales team to focus exclusively on driving our DEFINITY sales growth. Forthe year ended December 31, 2015, DEFINITY sales represented approximately 38% of our revenues. 7 Table of ContentsOur radiopharmaceutical products are sold in the United States through a small nuclear products sales team, primarily to radiopharmacies. We sell amajority of our radiopharmaceutical products in the United States to radiopharmacies that are controlled by or associated with Cardinal, UPPI, GE Healthcareand Triad. Our contractual distribution and other arrangements with these radiopharmacy groups are as follows: • Cardinal maintains approximately 131 radiopharmacies that are typically located in large, densely populated urban areas in the United States.We estimate that Cardinal’s radiopharmacies distributed approximately 40% of the aggregate U.S. SPECT doses sold in the first half of 2015 (thelatest information currently available to us). Our written supply agreements with Cardinal relating to TechneLite, Xenon, Neurolite, Cardioliteand certain other products expired in accordance with their terms on December 31, 2014. Following extended discussions with Cardinal, onNovember 19, 2015, the Company entered into a new contract for the distribution of TechneLite, Xenon, Neurolite and other products beginningin 2015 through 2017. The agreement specifies pricing levels and requirements to purchase minimum volumes of certain products during certainperiods. The agreement, which expires on December 31, 2017, may be terminated upon the occurrence of specified events, including a materialbreach by other party and certain force majeure events. From January 1, 2015 until the signing of the new agreement on November 19, 2015, wecontinued to accept and fulfill product orders from this major customer on a purchase order basis at supply price. • UPPI is a cooperative purchasing group (roughly analogous to a group purchasing organization) of approximately 77 independently owned orsmaller chain radiopharmacies located in the United States. UPPI’s radiopharmacies are typically broadly dispersed geographically, with someurban presence and a substantial number of radiopharmacies located in suburban and rural areas of the country. We estimate that theseindependent radiopharmacies, together with an additional 36 unaffiliated, independent radiopharmacies, distributed more than 28% of theaggregate U.S. SPECT doses sold in the first half of 2015. We currently have an agreement with UPPI for the distribution of TechneLite, Xenonand certain other products to radiopharmacies or families of radiopharmacies within the UPPI cooperative purchasing group. The agreementcontains specified pricing levels based upon specified purchase amounts for UPPI. We are entitled to terminate the UPPI agreement upon 60 dayswritten notice. The UPPI agreement expires on December 31, 2016. • GE Healthcare maintains 31 radiopharmacies in the United States that purchase our TechneLite generators. These radiopharmacies primarilydistribute GE Healthcare’s Myoview, a technetium-labeled MPI agent. We estimate that GE Healthcare distributed approximately 8% of theaggregate U.S. SPECT doses sold in the first half of 2015. We currently have an agreement with GE Healthcare for the distribution of TechneLite,Xenon and other products. The agreement provides that GE Healthcare will purchase a minimum percentage of TechneLite generators as well ascertain other products in the United States or Canada from us. Our agreement, which expires on December 31, 2017, may be terminated by eitherparty on (i) two years’ written notice relating to TechneLite and (ii) six months’ written notice relating to the other products. Our agreement alsoallows for termination upon the occurrence of specified events including a material breach by either party, bankruptcy by either party and forcemajeure events. • Triad maintains approximately 56 radiopharmacies in the United States that purchase a range of our products. We estimate that Triad distributedapproximately 18% of the aggregate U.S. SPECT doses sold in the first half of 2015. In June 2015, we entered into a new contract with Triad forthe distribution of Xenon, Neurolite and Cardiolite products and, beginning in 2016, TechneLite generators. The agreement specifies pricinglevels and requires Triad to purchase minimum volumes of certain products from the Company. The agreement expires on December 31, 2017and may be terminated upon the occurrence of specified events, including a material breach by the other party and certain force majeure events.In addition to the distribution arrangements for our radiopharmaceutical products described above, we also sell certain of our radiopharmaceuticalproducts to independent radiopharmacies and directly to hospitals and 8 Table of Contentsclinics that maintain in-house radiopharmaceutical capabilities and operations. In the latter case, this represents a small percentage of overall sales becausethe majority of hospitals and clinics do not maintain these in-house capabilities.In Europe, Asia Pacific and Latin America, we utilize third party distributor relationships to market, sell and distribute our products, either on acountry-by-country basis or on a multicountry regional basis. In October 2013, we entered into a new supply and distribution agreement for Cardiolite andNeurolite in certain European countries with Mallinckrodt AG. In March 2015, we terminated that agreement. In March 2012, we entered into a newdevelopment and distribution arrangement for DEFINITY in China, Hong Kong S.A.R. and Macau S.A.R. with Double-Crane Pharmaceutical Company, orDouble-Crane. Double-Crane is currently pursuing the Chinese regulatory approval required to commercialize the product. There are three milestones in theregulatory approval process to commercialize DEFINITY in China: • First, submission of a Clinical Trial Application which seeks Import Drug License approval. Double-Crane submitted the Clinical TrialApplication to the Chinese Food and Drug Administration, or CFDA, in June 2013. The CFDA accepted the Clinical Trial Application for reviewin July 2013. • Second, approval of the Clinical Trial Application, at which point Double-Crane can commence two small confirmatory clinical trials—one forabdominal (liver and kidney) and one for cardiac. The CFDA approved the Clinical Trial Application in February 2016. • Third, approval of the Import Drug License. If the regulatory process, including the clinical trials, is successful, we currently estimate the timingfor approval of DEFINITY in China could be as soon as 2017.We believe that international markets, particularly China, represent significant growth opportunities for our products. The Mallinckrodt and Double-Crane distribution agreements did not have a significant impact on our revenue during 2015.As of December 31, 2015, we sold our products (and others) directly to end users through four radiopharmacies that we either owned or operated inCanada, the two radiopharmacies we own in Australia and the one radiopharmacy we own in Puerto Rico. On January 12, 2016, we sold our Canadianradiopharmacies to Isologic and entered into a long-term supply agreement with Isologic under which we will supply Isologic with certain of our products oncommercial terms, including certain product purchase commitments by Isologic. The agreement expires on January 12, 2021 and may be terminated upon theoccurrence of specified events, including a material breach by the other party, bankruptcy by either party and certain force majeure events. We also maintainour own direct sales forces in these markets so we can control the importation, marketing, distribution and sale of our imaging agents in these regions.CustomersFor the year ended December 31, 2015, our largest customers were UPPI, Cardinal, and GE Healthcare, accounting for 12%, 11% and 10%, respectively,of our revenues.CompetitionWe believe that our key product characteristics, such as proven efficacy, reliability and safety, coupled with our core competencies, such as ourefficient manufacturing processes, our established distribution network, our experienced field sales organization and our customer service focus, areimportant factors that distinguish us from our competitors.The market for diagnostic medical imaging agents is highly competitive and continually evolving. Our principal competitors in existing diagnosticmodalities include large, global companies that are more diversified than we are and that have substantial financial, manufacturing, sales and marketing,distribution and other resources. These competitors include Mallinckrodt, GE Healthcare, Bayer, Bracco and DRAXIS Specialty 9 Table of ContentsPharmaceuticals Inc. (an affiliate of JHS), or Draxis, as well as other competitors. We cannot anticipate their competitive actions in the same or competingdiagnostic modalities, such as significant price reductions on products that are comparable to our own, development of new products that are more cost-effective or have superior performance than our current products or the introduction of generic versions after our proprietary products lose their current patentprotection. In addition, distributors of our products could attempt to shift end-users to competing diagnostic modalities and products. Our current or futureproducts could be rendered obsolete or uneconomical as a result of these activities.Generic competition has substantially eroded our market share for Cardiolite, beginning in September 2008 when the first generic product waslaunched. We are currently aware of four separate, third party generic offerings of sestamibi. We also sell our own generic version of sestamibi. See “Item 1A—Risk Factors—Generic competition has significantly eroded our market share of the MPI segment for Cardiolite products and will continue to do so.”Raw Materials and Supply RelationshipsWe rely on certain raw materials and supplies to produce our products. Due to the specialized nature of our products and the limited, and sometimesintermittent, supply of raw materials available in the market, we have established relationships with several key suppliers. Our most important and widelyused raw material is Moly. For the year ended December 31, 2015, our largest supplier of raw materials and supplies was Nordion, accounting forapproximately 13% of our total purchases.Molybdenum-99Our TechneLite, Cardiolite and Neurolite products all rely on Moly, the radioisotope which is produced by bombarding Uranium-235 with neutrons inresearch reactors. Moly is the most common radioisotope used for medical diagnostic imaging purposes. With a 66-hour half-life, Moly decays into amongother things technetium-99m, (Tc-99m), another radioisotope with a half-life of six hours. Tc-99m is the isotope that is attached to radiopharmaceuticals,including our own Cardiolite and Neurolite, during the labeling process.We currently purchase finished Moly from four of the five main processing sites in the world, namely, ANSTO in Australia; Institute for Radioelements,or IRE, in Belgium; Nordion, formerly known as MDS Nordion, in Canada; and NTP Radioisotopes, or NTP, in South Africa. These processing sites are, inturn, supplied by six of the seven main Moly-producing reactors in the world, namely, OPAL in Australia; BR2 in Belgium; LVR-10 in the Czech Republic;High Flux Reactor, or HFR, in The Netherlands; NRU in Canada; and SAFARI in South Africa.Historically, our largest supplier of Moly has been Nordion, which relies on the NRU reactor for its supply of Moly. Our agreement with Nordioncontains minimum percentage purchase requirements for Moly. The agreement allows for termination upon the occurrence of certain events. Nordion canterminate if we fail to purchase a minimum percentage of Moly or if Nordion incurs certain cost increases. Either party may terminate if the other party fails tocomply with material obligations, is bankrupt or experiences a force majeure event subject to a waiting period. The current agreement expires on October 31,2016, and the NRU reactor has announced a transition in 2016 from providing regular supply of medical isotopes to providing only emergency back-upsupply of HEU based medical isotopes from November 1, 2016 through March 2018.Our agreement with NTP includes their consortium partner, ANSTO. ANSTO has under construction, in cooperation with NTP, a new Moly processingfacility that ANSTO believes will expand its production capacity by approximately 2.5 times, with expanded commercial production planned to start in thelatter part of 2016. In addition, IRE recently received approval from its regulator to expand its production capability by up to 50% of its former capacity. Thisnew ANSTO and IRE production capacity is expected to replace the NRU’s current routine production. The NTP/ANSTO agreement contains minimumpercentage volume requirements and 10 Table of Contentsprovides for the increased supply of Moly derived from LEU targets from NTP and ANSTO. The agreement allows for termination upon the occurrence ofcertain events, including failure by NTP to provide our required amount of Moly, material breach of any provision by either party, bankruptcy by either partyand force majeure events. Additionally, we have the ability to terminate the agreement with six months’ written notice prior to the expiration of theagreement. The agreement expires on December 31, 2017.In March 2013, we entered into a similar agreement with IRE, or the IRE Agreement. IRE previously supplied us as a subcontractor under theagreement with NTP/ANSTO. Similar to the agreement with NTP/ANSTO, the IRE Agreement contains minimum percentage volume requirements. The IREAgreement also requires IRE to provide certain increased quantities of Moly during periods of supply shortage or failure. The IRE Agreement also providesfor an increased supply of Moly derived from LEU targets upon IRE’s completion of its ongoing conversion program to modify its facilities and processes inaccordance with Belgian nuclear security commitments. The IRE Agreement allows for termination upon the occurrence of certain events, including failureby IRE to provide our required amount of Moly, material breach of any provision by either party, bankruptcy by either party and force majeure events. TheIRE Agreement expires on December 31, 2017.To further augment and diversify our current supply, we are pursuing additional sources of Moly from potential new producers around the world thatseek to produce Moly with existing or new reactors or technologies. For example, in November 2014, we announced entering into a new strategic agreementwith SHINE Medical Technologies, Inc., a Wisconsin-based company, or SHINE, for the future supply of Moly. Under the terms of the supply agreement,SHINE will provide Moly produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomesoperational and receives all necessary regulatory approvals, which SHINE currently estimates will occur in 2019. See “Item 1A—Risk Factors—The globalsupply of Moly is fragile and not stable. Our dependence on a limited number of third party suppliers for Moly could prevent us from delivering some of ourproducts to our customers in the required quantities, with the required timeframe, or at all, which could result in order cancellations and decreased revenues.”XenonCurrently, Nordion is our sole supplier of Xenon, and we believe it is currently the principal supplier of Xenon in the world. Xenon is captured by theNRU reactor as a by-product of the Moly production process. Our agreement with Nordion is on a purchase order basis. As a result of this transaction, oursupplier could change the terms on which we obtain Xenon. In January 2015, we announced entering into a new strategic agreement with IRE for the futuresupply of Xenon. Under the terms of the agreement, IRE will provide bulk Xenon to us for processing and finishing once development work has beencompleted and all necessary regulatory approvals have been obtained. We currently estimate commercial production will occur in 2016. If we are not able tobegin providing commercial quantities of Xenon prior to the NRU reactor’s announced medical isotope supply transition in October 2016, there may be aperiod of time during which we are not able to offer Xenon in our portfolio of commercial products. See “Item 1A—Risk Factors—We face potential supplyand demand challenges for Xenon.”Other MaterialsWe have additional supply arrangements for APIs, excipients, packaging materials and other materials and components, none of which are exclusive,but a number of which are sole source, and all of which we currently believe are either in good standing or replaceable without any material disruption to ourbusiness.ManufacturingWe maintain manufacturing operations at our North Billerica, Massachusetts facility. We manufacture TechneLite on a highly automated productionline and also manufacture Thallium and Gallium at this site using our cyclotron technology and Xenon using our hot cell infrastructure. We manufacture,finish and distribute our 11 Table of Contentsradiopharmaceutical products on a just-in-time basis, and supply our customers with these products either by next day delivery services or by either groundor air custom logistics. We believe that our substantial capital investments in our highly automated generator production line, our cyclotrons and ourextensive experience in complying with the stringent regulatory requirements for the handling of nuclear materials and operations in the FDA regulatedenvironment create significant and sustainable competitive advantages for us.In addition to our in-house manufacturing capabilities, a substantial portion of our products are manufactured by third party contract manufacturingorganizations, and in certain instances, we rely on them for sole source manufacturing. To ensure the quality of the products that are manufactured by thirdparties, the key raw materials used in those products are first sent to our North Billerica facility, where we test them prior to the third party manufacturing ofthe final product. After the final products are manufactured, they are sent back to us for final quality control testing and then we ship them to our customers.We have expertise in the design, development and validation of complex manufacturing systems and processes, and our strong execution and quality controlculture supports the just-in-time manufacturing model at our North Billerica facility.BVL, JHS and PharmalucenceHistorically, we relied on Ben Venue Laboratories, or BVL, as our sole manufacturer of DEFINITY, Neurolite and evacuation vials, an ancillarycomponent for our TechneLite generators, and as one of our two manufacturers of Cardiolite. Following extended operational and regulatory challenges atBVL’s Bedford, Ohio facility, in March 2012, we entered into a settlement arrangement with BVL, resulting in an aggregate payment to us of $35.0 million, abroad mutual waiver and a covenant by us not to sue. Later in 2012 and in 2013, BVL continued to attempt to manufacture our products for us, and inOctober 2013 announced that it would cease to manufacture new batches of our products at its Bedford, Ohio facility. In November 2013, we entered into asecond settlement arrangement with BVL, resulting in an additional aggregate payment to us of $8.9 million, a broad mutual waiver and a covenant by us notto sue.Contemporaneous with the BVL supply challenges, we expedited a number of technology transfer programs to secure and qualify production of ourBVL-manufactured products from alternate contract manufacturer sites. • DEFINITY—We entered into a Manufacturing and Supply Agreement, effective as of February 1, 2012, with JHS, for the manufacture ofDEFINITY. Under the agreement, JHS manufactures DEFINITY for us for an initial term of five years. We have the right to extend the agreementfor an additional five-year period, with automatic renewals for additional one year periods thereafter. The agreement allows for termination uponthe occurrence of certain events such as a material breach or default by either party, or bankruptcy by either party. The agreement also requires usto place orders for a minimum percentage of our requirements for DEFINITY with JHS.On November 12, 2013, we entered into a Manufacturing and Supply Agreement with Pharmalucence to manufacture and supply DEFINITY andwe are currently in the technology transfer process with Pharmalucence in order to diversify our supply. We currently anticipate that we will filefor FDA approval in 2016 to manufacture DEFINITY at Pharmalucence. There are no minimum purchase requirements under this agreement,which has an initial term of five years from the effective date and is renewable at our option for an additional five years. The ManufacturingAgreement allows for termination upon the occurrence of certain events, including material breach or bankruptcy by either party. During theoptional five year term, either party may terminate upon thirty months advance notice. Based on our current projections, we believe that we willhave sufficient supply of DEFINITY from JHS to meet expected demand. • Cardiolite—For the past several years, we have relied on Bristol-Myers Squibb Company, or BMS’ Manati, Puerto Rico site for the manufactureof our Cardiolite supply. This relationship ended on December 31, 2015 following the completion of a terminal inventory build for ourCardiolite product. We also entered into a Manufacturing and Supply Agreement, effective as of May 3, 2012, with JHS for the manufacture ofCardiolite products. We are currently in the technology transfer process and 12 Table of Contents anticipate that we will file for FDA approval in 2016 to manufacture Cardiolite at JHS. Under the agreement, JHS has agreed to manufactureproduct for an initial term of five years. We have the right to extend the agreement for an additional five-year period, with automatic renewals foradditional one year periods thereafter. The agreement allows for termination upon the occurrence of specified events, including material breachor bankruptcy by either party. The agreement requires us to place orders for a minimum percentage of our requirements for Cardiolite with JHSduring such term. Based on our current projections, we believe that we will have sufficient Cardiolite product supply from our current supplierand JHS for when the technology transfer process is completed and we have obtained regulatory approval for this manufacturing site to meetexpected demand. • Neurolite—We entered into a Manufacturing and Supply Agreement, effective as of May 3, 2012, with JHS for the manufacture of Neurolite, andin January 2015, the FDA granted approval to JHS to be a new manufacturing site for this product. Under the agreement, JHS has agreed tomanufacture product for an initial term of five years. We have the right to extend the agreement for an additional five-year period, with automaticrenewals for additional one year periods thereafter. The agreement allows for termination upon the occurrence of specified events, includingmaterial breach or bankruptcy by either party. The agreement also requires us to place orders for a minimum percentage of our requirements forNeurolite with JHS during such term. Based on our current projections, we believe that we will have sufficient supply of Neurolite from JHS tomeet expected demand.Our manufacturing agreement for Ablavar has terminated. We do not have any current plans to initiate technology transfer activities for Ablavar. Ourexisting Ablavar inventory will expire in the third quarter of 2016, and we will have no further Ablavar inventory that we will be able to sell unless and untilwe engage in Ablavar technology transfer activities in the future with a new manufacturing partner.Although we are pursuing new manufacturing relationships to establish and secure additional long-term or alternative suppliers as described above, weare uncertain of the timing as to when these arrangements could provide meaningful quantities of product. See “Item 1A—Risk Factors—Risks Relating toOur Business and Industry—The global supply of Moly is fragile and not stable. Our dependence on a limited number of third party suppliers for Moly couldprevent us from delivering some of our products to our customers in the required quantities, within the required timeframes, or at all, which could result inorder cancellations and decreased revenues,” “Item 1A—Risk Factors—Challenges with product quality or product performance, including defects, causedby us or our suppliers could result in a decrease in customers and sales, unexpected expenses and loss of market share” and “Item 1A—Risk Factors—Ourbusiness and industry are subject to complex and costly regulations. If government regulations are interpreted or enforced in a manner adverse to us or ourbusiness, we may be subject to enforcement actions, penalties, exclusion and other material limitations on our operations.”PET Manufacturing FacilitiesIf flurpiridaz F 18 is ultimately successful in clinical trials, a new manufacturing model will have to be implemented where chemical ingredients of theimaging agent are provided to PET radiopharmacies that have fluorine-18 radioisotope-producing cyclotrons on premises. The radiopharmacies will combinethese chemical ingredients with fluorine-18 they manufactured in specially designed chemistry synthesis boxes to generate the final radiopharmaceuticalimaging agent, flurpiridaz F 18. Radiopharmacists will be able to prepare and dispense patient-specific doses from the final product. However, because eachof these PET radiopharmacies will be deemed by the FDA to be a separate manufacturing site for flurpiridaz F 18, each of the radiopharmacies will have to beincluded in the agent’s NDA and subsequent FDA filings. As a result, there will be quality and oversight responsibilities of the PET radiopharmaciesassociated with the NDA, unlike the current relationship we have with our nuclear imaging agent distributors that operate radiopharmacies. See “—Researchand Development—Flurpiridaz F 18 Phase 3 Program.” 13 Table of ContentsResearch and DevelopmentFor the years ended December 31, 2015, 2014 and 2013, we invested $14.4 million, $13.7 million, and $30.5 million, respectively, in research anddevelopment, or R&D. Our R&D team includes our medical affairs and medical information functions, which educate physicians on the scientific aspects ofour commercial products and the approved indications, labeling and the receipt of reports relating to product quality or adverse events. We have developed apipeline of three potential cardiovascular imaging agents which were discovered and developed in-house and which are protected by patents and patentapplications we own in the United States and numerous foreign jurisdictions.In March 2013, we began to implement a strategic shift in how we will fund our important R&D programs. We have reduced our internal R&Dresources while at the same time we seek to engage strategic partners to assist us in the further development and commercialization of these agents, includingflurpiridaz F 18, 18F LMI 1195 and LMI 1174. See “Item 1A—Risk Factors—Risks Relating to our Business and Industry—We will not be able to furtherdevelop or commercialize our agents in development without successful strategic partners.”Flurpiridaz F 18—PET Perfusion Agent—Myocardial PerfusionWe have developed flurpiridaz F 18, an internally discovered small molecule radiolabeled with fluorine-18, as an imaging agent used in PET MPI toassess blood flow to the heart.Today, most MPI procedures use SPECT technology. Although this imaging modality provides substantial clinical value, there is growing interest inthe medical community to utilize technology such as PET that can provide meaningful advantages. PET is an imaging technology that when used incombination with an appropriate radiopharmaceutical imaging agent can provide important insights into physiologic and metabolic processes in the bodyand be useful in evaluating a variety of conditions including neurological disease, heart disease and cancer. PET imaging has demonstrated broad utility fordiagnosis, prognosis, disease staging and therapeutic response. Images generated with PET technology typically exhibit very high image resolution becauseof substantially higher signal-to-noise efficiency, a measure of the efficiency by which energy can be captured to create an image.Although SPECT imaging used in conjunction with a radiopharmaceutical imaging agent, such as Cardiolite, is most commonly used for MPI studies,PET imaging has gained considerable support in the field of cardiovascular imaging as it offers many advantages to SPECT imaging, including: higher imagequality, increased diagnostic certainty, more accurate risk stratification and reduced patient radiation exposure. In addition, PET MPI imaging could beparticularly useful in difficult to image patients, including women and obese patients. The use of PET technology in MPI tests represents a broad emergingapplication for a technology more commonly associated with oncology and neurology. We anticipate that the adoption of PET technology in MPI tests willincrease significantly in the future.Flurpiridaz F 18 Clinical OverviewWe submitted an Investigational New Drug Application, or IND, for flurpiridaz F 18 to the FDA in August 2006. Our clinical program to date hasconsisted of three Phase 1 studies, a Phase 2 clinical trial, conducted from 2007 to 2010, involving 176 subjects who received PET MPI performed withflurpiridaz F 18 and completed the trial, and a Phase 3 clinical trial conducted from 2011 to 2013 involving 755 subjects who received PET MPI procedureswith flurpiridaz F 18, completed the trial and were included in the efficacy analysis.Flurpiridaz F 18 Phase 2 TrialWe evaluated flurpiridaz F 18 in a Phase 2 trial consisting of 176 subjects who completed the trial from 21 centers. These subjects underwent bothSPECT and PET MPI with flurpiridaz at rest and at stress and were evaluated for safety. Of these subjects, 86 underwent coronary angiography, the currentstandard clinical method 14 Table of Contentsfor diagnosing coronary artery disease. Coronary angiography is an invasive procedure using fluoroscopy performed in a cardiac catheterization lab while thesubject is under mild sedation. These 86 subjects formed the population for evaluating diagnostic performance.The PET MPI that was performed with flurpiridaz F 18 at stress utilized either pharmacological coronary vasodilation or treadmill exercise. Unlikecurrently available PET imaging agents for MPI with half-lives measured in seconds, flurpiridaz F 18 can be used in conjunction with treadmill exercisegiven its substantially longer 110 minute half-life.The Phase 2 trial results showed the following: • a significantly higher percentage of images were rated as either excellent or good quality with PET imaging, compared to SPECT imaging forstress images (98.8% vs. 84.9%, p<0.01) and rest images (95.3% vs. 69.8%, p<0.01); • diagnostic certainty of interpretation, the percentage of cases with definitely abnormal or definitely normal interpretation, was significantlyhigher for flurpiridaz F 18 compared to SPECT (90.7% vs. 75.6%, p<0.01); • the area under the ROC curve (the relative operating characteristic curve comparing the true positive rate to the false positive rate for coronaryartery disease diagnosis) was significantly higher for flurpiridaz F 18 than SPECT (0.82±0.05 vs. 0.70±0.05, p<0.05), indicating higherdiagnostic performance; • superiority for sensitivity (that is, the ability to identify disease) with flurpiridaz F 18 imaging was significantly higher than SPECT (78.8% vs.61.5%, p=0.02); • a trend toward higher specificity (that is, the ability to rule out disease) was noted, although the advantage was not statistically significant in thestudy; and • no drug-related serious adverse events were observed, demonstrating a positive safety profile for PET MPI imaging with flurpiridaz F 18.Flurpiridaz F 18 Phase 3 ProgramTo date, our Phase 3 program for flurpiridaz F 18 has included a phase 3 trial (study 301), which was an open-label, multicenter, international studywith 755 subjects with known or suspected coronary artery disease, or CAD, and scheduled for coronary angiography and SPECT imaging who completed thetrial and were included in the efficacy analysis. Subjects underwent flurpiridaz F 18 PET MPI and SPECT MPI studies with coronary angiography used as thetruth standard for each. The study then compared MPI imaging using flurpiridaz F 18 versus SPECT with primary endpoints of superiority for sensitivity(identifying disease) and non-inferiority for specificity (ruling out disease).In March 2011, we obtained agreement from the FDA on a Special Protocol Assessment, or SPA, for our 301 trial. See “Business—Regulatory Matters—Food and Drug Laws.” In June 2011, we enrolled our first patient, and we completed patient enrollment in the third quarter of 2013In the fourth quarter of 2013, we announced preliminary results from the 301 trial. Flurpiridaz F 18 appeared to be well-tolerated from a safetyperspective and outperformed SPECT in a highly statistically significant manner in sensitivity. In addition, flurpiridaz F 18 showed statistically significantimprovements in image quality and diagnostic certainty in comparison to SPECT. However, flurpiridaz F 18 did not meet the co-primary endpoint of non-inferiority for specificity.In the fourth quarter of 2014, we completed a re-read of the 301 trial results, and in May 2015, we announced the complete results from the 301 trial.PET MPI with flurpiridaz F 18 consistently showed a balanced performance in sensitivity and specificity, when compared to coronary angiography, whileSPECT 15 Table of Contentsimaging results were skewed with low sensitivity and high specificity when compared to coronary angiography. When the flurpiridaz F 18 results werecompared to the SPECT results, flurpiridaz F 18 substantially outperformed SPECT in sensitivity but did not meet the non-inferiority endpoint in specificity,implying a substantial and unexpected under-diagnosis of CAD with SPECT imaging in the trial.In subgroup analyses, the risk-benefit profile of flurpiridaz F 18 appeared to be favorable in women, obese patients and patients with multivesseldisease. A significantly higher percentage of images were rated as either excellent or good with flurpiridaz F 18 as compared to SPECT, leading to a greaterdiagnostic certainty of interpretation. Importantly, radiation exposure associated with flurpiridaz F 18 was reduced to approximately 50% of SPECT. Inaddition, no drug-related serious adverse events were observed.Based on these results, we have redesigned the protocol for our second Phase 3 trial with different primary endpoints. On March 13, 2015, the FDAgranted us an SPA in connection with the new trial. We are currently in diligence discussions with several companies for potential partnership of flurpiridaz F18. We are evaluating global, regional and functional opportunities relating to development, manufacturing and commercialization. After we finalize one ormore of these partnering opportunities, we will then commence the second Phase 3 trial, which we currently believe will take between two and three years tocomplete. See “Item 1A—Risk Factors—The process of developing new drugs and obtaining regulatory approval is complex, time-consuming and costly,and the outcome is not certain.”18F LMI 1195—Cardiac Neuronal Activity Imaging AgentWe have developed 18F LMI 1195, also an internally discovered small molecule that is a fluorine-18-based radiopharmaceutical imaging agent,designed to assess cardiac sympathetic nerve function with PET. Sympathetic nerve activation increases the heart rate, constricts blood vessels and raisesblood pressure by releasing a neurotransmitter called norepinephrine throughout the heart. Changes in the cardiac sympathetic nervous system have beenassociated with heart failure progression and fatal arrhythmias.Heart failure is a major public health problem in North America, associated with high morbidity and mortality, frequent hospitalizations and a majorcost burden on the community. In the United States alone, there are over five million patients living with congestive heart failure, and over a half million newdiagnoses each year. Mortality for this condition is around 50% within five years of diagnosis. Expensive therapies for heart failure are often utilized withouteffective predictors of patient response. Costly device therapies (for example, implantable cardiac defibrillators, or ICDs, and cardiac resynchronizationtherapy) are often used, although they sometimes do not provide any benefits or are activated in only a minority of recipients. Conversely, heart failureclinical practice guidelines currently preclude the use of device therapy in many patients who might benefit. Thus, a key opportunity is to better matchpatients to treatment based on the identification of the underlying molecular status of disease progression.18F LMI 1195 is taken up by the transporter that regulates norepinephrine released by the sympathetic nervous system at multiple nerve endings of theheart. PET imaging using 18F LMI 1195 could allow for the identification of patients at risk of sudden death, potentially improving clinical decision-making, including identifying which patients could benefit from certain drug therapies or the implantation of certain anti-arrhythmia devices such as ICDs.We have completed a Phase 1 study of 18F LMI 1195 using PET imaging. 12 normal subjects were injected intravenously with approximately sixmillicuries of 18F LMI 1195, imaged sequentially for a period of approximately five hours and monitored closely to observe any potential adverse events.Excellent quality images were obtained, and the radiation dose to the subjects was found to be well within acceptable limits. Blood radioactivity clearedquickly and lung activity was low throughout the study. The agent appeared to have a favorable safety profile. We are currently working closely withindependent investigators in the United States, Canada and Europe to develop additional clinical data which may allow us to enter into pivotal clinical trials.We are seeking to engage strategic partners to assist us with the ongoing development activities relating to this agent. 16 Table of ContentsLMI 1174—Vascular Remodeling Imaging AgentWe have developed LMI 1174, an internally discovered gadolinium-based MRI agent targeted to elastin in the arterial walls and atheroscleroticplaque. We believe that this agent could allow assessment of plaque location, burden, type of arterial wall remodeling and, as a result, the potential for avascular event, which, in turn, could lead to heart attack or stroke.Atherosclerosis is the leading cause of heart attacks, strokes and peripheral vascular disease. Elastin plays a key role in the structure of the arterial walland in biological signaling functions. Several pathological stimuli may be responsible for triggering elastogenesis in atherosclerosis, leading to a markedincrease in elastin content during plaque development. In addition to the increase in elastin seen in autopsy samples from patients with carotidatherosclerosis, there is also an increase of elastin in aortic aneurysm samples. As a result, an elastin-specific imaging agent may facilitate detection ofremodeling of the arterial walls.The majority of the assessments of atherosclerosis are currently obtained using angiography or MPI. MRI using LMI 1174 could allow for theidentification, on a minimally-invasive basis without radiation exposure, of the presence and characteristics of atherosclerosis, potentially improving clinicaldecision-making to reduce the risks of cardiovascular events.In our preclinical work, we have identified a series of low molecular weight molecules that bind to elastin and final optimization is ongoing. Our leadmolecule, LMI 1174, has been used to demonstrate utility in a number of different animal models. We are seeking to engage strategic partners to assist uswith the ongoing development activities relating to this agent.Intellectual PropertyPatents, trademarks and other intellectual property rights, both in the United States and foreign countries, are very important to our business. We alsorely on trade secrets, manufacturing know-how, technological innovations and licensing agreements to maintain and improve our competitive position. Wereview third party proprietary rights, including patents and patent applications, as available, in an effort to develop an effective intellectual property strategy,avoid infringement of third party proprietary rights, identify licensing opportunities and monitor the intellectual property owned by others. Our ability toenforce and protect our intellectual property rights may be limited in certain countries outside the United States, which could make it easier for competitorsto capture market position in those countries by utilizing technologies that are similar to those developed or licensed by us. Competitors also may harm oursales by designing products that mirror the capabilities of our products or technology without infringing our intellectual property rights. If we do not obtainsufficient protection for our intellectual property, or if we are unable to effectively enforce our intellectual property rights, our competitiveness could beimpaired, which would limit our growth and future revenue.Trademarks, Service Marks and Trade NamesWe own various trademarks, service marks and trade names, including DEFINITY, TechneLite, Cardiolite, Neurolite, Ablavar, Vialmix, Quadramet(U.S. only) and Lantheus Medical Imaging. We have registered these trademarks, as well as others, in the United States and numerous foreign jurisdictions.PatentsWe actively seek to protect the proprietary technology that we consider important to our business, including chemical species, compositions andformulations, their methods of use and processes for their manufacture, as new intellectual property is developed. In addition to seeking patent protection inthe United States, we file patent applications in numerous foreign countries in order to further protect the inventions that we consider important to thedevelopment of our international business. We also rely upon trade secrets and contracts to protect our proprietary information. As of January 31, 2016, ourpatent portfolio included a total of 33 issued 17 Table of ContentsU.S. patents, 192 issued foreign patents, 20 pending patent applications in the United States and 167 pending foreign applications. These patents and patentapplications include claims covering the composition of matter and methods of use for all of our preclinical and clinical stage agents.Our patents cover many of our commercial products, and our current patent protection is generally in the United States, Canada, Mexico, most ofWestern Europe, various markets in Asia, and Brazil. For DEFINITY, we hold a number of different compositions of matter, use, formulation andmanufacturing patents, with U.S. patent protection until 2021 and patent or regulatory extension protection in Canada, Europe and parts of Asia until 2019,and we have an active next generation program for this agent. TechneLite currently has patent protection in the United States and various foreign countrieson certain component technology expiring in 2029. In addition, given the significant know-how and trade secrets associated with the methods ofmanufacturing and assembling the TechneLite generator, we believe we have a substantial amount of valuable and defensible proprietary intellectualproperty associated with the product. Neither Cardiolite nor Neurolite is covered any longer by patent protection in either the United States or the rest of theworld. For Ablavar, we hold a number of different composition of matter, use, formulation and manufacturing patents, with a composition of matter U.S.patent not expiring until 2020 with regulatory extension and a manufacturing patent application, which if granted, will expire in 2034 in the absence of anypatent term adjustment or regulatory extension. Xenon, Thallium and Gallium are all generic radiopharmaceuticals.We have numerous patents and patent applications relating to our clinical development pipeline. We have patents and patent applications in numerousjurisdictions covering composition, use, formulation and manufacturing of flurpiridaz F 18, including in the United States a composition patent expiring in2026, a method of use patent expiring in 2028 and a method of manufacturing patent expiring in 2031, in the absence of any regulatory extension, andvarious patent applications, one of which, if granted, will expire in 2033. We also have patents and patent applications in numerous jurisdictions coveringcomposition, use, and manufacture of 18F LMI 1195, our cardiac neuronal imaging agent, including in the United States a composition patent expiring in2030 in the absence of any regulatory extension, and patent applications which, if granted, will expire in 2027 and in 2031 in the absence of any patent termadjustment or regulatory extensions. Additionally, we have patents and patent applications in numerous jurisdictions covering composition, use andmanufacture of LMI 1174, our vascular remodeling imaging agent, including in the United States a composition and method of use patent expiring in 2031in the absence of any regulatory extension, and patent applications which, if granted, will expire in 2029 and 2030 in the absence of any patent termadjustment or regulatory extensions.In addition to patents, we rely where necessary upon unpatented trade secrets and know-how, proprietary information and continuing technologicalinnovation to develop and maintain our competitive position. We seek to protect our proprietary information, in part, using confidentiality agreements withour collaborators, employees, consultants and other third parties and invention assignment agreements with our employees. These confidentiality agreementsmay not prevent unauthorized disclosure of trade secrets and other proprietary information, and we cannot assure you that an employee or an outside partywill not make an unauthorized disclosure of our trade secrets, other technical know-how or proprietary information. We may not have adequate monitoringabilities to discover, or adequate remedies for, any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitorwill make use of such information, and that our competitive position will be compromised, in spite of any legal action we might take against persons makingsuch unauthorized disclosures. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent thatour collaborators, employees and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related orresulting know-how and inventions.In addition, we license a limited number of third party technologies and other intellectual property rights that are incorporated into some elements ofour drug discovery and development efforts. These licenses are not material to our business, and the technologies can be obtained from multiple sources. Weare currently party to separate royalty-free, non-exclusive, cross-licenses with each of Bracco, GE Healthcare and Imcor 18 Table of ContentsPharmaceutical Company. These cross-licenses give us freedom to operate in connection with contrast enhanced ultrasound imaging technology. We also in-license certain freedom to operate rights for Ablavar from, among others, Bayer.Regulatory MattersFood and Drug LawsThe development, manufacture and commercialization of our agents and products are subject to comprehensive governmental regulation both withinand outside the United States. A number of factors substantially increase the time, difficulty and costs incurred in obtaining and maintaining the approval tomarket newly developed and existing products. These factors include governmental regulation, such as detailed inspection of and controls over research andlaboratory procedures, clinical investigations, manufacturing, marketing, sampling, distribution, import and export, record keeping and storage and disposalpractices, together with various post-marketing requirements. Governmental regulatory actions can result in the seizure or recall of products, suspension orrevocation of the authority necessary for their production and sale as well as other civil or criminal sanctions.Our activities in the development, manufacture, packaging or repackaging of our pharmaceutical and medical device products subjects us to a widevariety of laws and regulations. We are required to register for permits and/or licenses with, seek approvals from and comply with operating and securitystandards of the FDA, the U.S. Nuclear Regulatory Commission, or the NRC, the U.S. Department of Health and Human Services, or the HHS, Health Canada,the European Medicines Agency, or the EMA, the U.K. Medicines and Healthcare Products Regulatory Agency, or MHRA, the CFDA and various state andprovincial boards of pharmacy, state and provincial controlled substance agencies, state and provincial health departments and/or comparable state andprovincial agencies, as well as foreign agencies, and certain accrediting bodies depending upon the type of operations and location of product distribution,manufacturing and sale.The FDA and various state regulatory authorities regulate the research, testing, manufacture, safety, labeling, storage, recordkeeping, premarketapproval, marketing, advertising and promotion, import and export and sales and distribution of pharmaceutical products in the United States. Prior tomarketing a pharmaceutical product, we must first receive FDA approval. Specifically, in the United States, the FDA regulates drugs under the Federal Food,Drug, and Cosmetic Act, or FDCA, and implementing regulations. The process of obtaining regulatory approvals and compliance with appropriate federal,state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources. Currently, the process required by theFDA before a drug product may be marketed in the United States generally involves the following: • completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices regulations; • submission to the FDA of an IND which must become effective before human clinical studies may begin; • performance of adequate and well-controlled human clinical studies according to Good Clinical Practices and other requirements, to establishthe safety and efficacy of the proposed drug product for its intended use; • submission to the FDA of a New Drug Application, or NDA, for a new drug; • satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug product is produced to assesscompliance with current Good Manufacturing Practices, or cGMPs, regulations; and • FDA review and approval of the NDA. 19 Table of ContentsThe testing and approval process requires substantial time, effort, and financial resources, and we cannot be certain that any approvals for our agents indevelopment will be granted on a timely basis, if at all. Once a pharmaceutical agent is identified for development, it enters the preclinical testing stage.Preclinical tests include laboratory evaluations of product chemistry, toxicity, formulation, and stability, as well as animal studies to assess its potentialsafety and efficacy. This testing culminates in the submission of the IND to the FDA.Once the IND becomes effective, the clinical trial program may begin. Each new clinical trial protocol must be submitted to the FDA before the studymay begin. Human clinical studies are typically conducted in three sequential phases that may overlap or be combined:Phase 1. The agent is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution andexcretion. In the case of some products for severe or life-threatening diseases, especially when the agent may be too inherently toxic to ethicallyadminister to healthy volunteers, the initial human testing is often conducted in patients with those diseases.Phase 2. Involves studies in a limited patient population to identify possible adverse effects and safety risks, to evaluate preliminarily the efficacy ofthe agent for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.Phase 3. Clinical studies are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographicallydispersed clinical study sites. These studies are intended to collect sufficient safety and effectiveness data to support the NDA for FDA approval.Clinical trial sponsors may request an SPA from the FDA. The FDA’s SPA process creates a written agreement between the sponsoring company and theFDA regarding the clinical trial design and other clinical trial issues that can be used to support approval of an agent. The SPA is intended to provideassurance that, if the agreed-upon clinical trial protocols are followed and the trial endpoints are achieved, then the data may serve as the primary basis for anefficacy claim in support of an NDA. However, the SPA agreement is not a guarantee of an approval of an agent or any permissible claims about the agent. Inparticular, the SPA is not binding on the FDA if public health concerns become evident that are unrecognized at the time that the SPA agreement is enteredinto, other new scientific concerns regarding product safety or efficacy arise, or if the clinical trial sponsor fails to comply with the agreed upon clinical trialprotocols.Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and safety reports must be submitted to theFDA and the investigators for serious and unexpected adverse events. Submissions must also be made to inform the FDA of certain changes to the clinicaltrial protocol. Federal law also requires the sponsor to register the trials on public databases when they are initiated, and to disclose the results of the trials onpublic databases upon completion. Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within any specified period, if at all. The FDA orthe clinical trial sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the research subjects or patientsare being exposed to an unacceptable health risk. Similarly, any institutional review board, or IRB, serving any of the institutions participating in the clinicaltrial can suspend or terminate approval of a clinical study at a relevant institution if the clinical study is not being conducted in accordance with the IRB’srequirements or if the agent has been associated with unexpected serious harm to patients. Failure to register a clinical trial or disclose study results within therequired time periods could result in penalties, including civil monetary penalties.Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional information about thechemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMPrequirements. The manufacturing process must be capable of consistently producing quality batches of the agent and, among other things, the manufacturermust develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected andtested and stability studies must be conducted to demonstrate that the agent does not undergo unacceptable deterioration over its shelf life. 20 Table of ContentsThe results of product development, preclinical studies and clinical studies, along with descriptions of the manufacturing process, analytical testsconducted on the drug product, proposed labeling, and other relevant information, are submitted to the FDA as part of an NDA for a new drug, requestingapproval to market the agent. The submission of an NDA is subject to the payment of a substantial user fee, pursuant to the Prescription Drug User Fee Act, orPDUFA, which was first enacted in 1992 to provide the FDA with additional resources to speed the review of important new medicines. A waiver of that feemay be obtained under certain limited circumstances. PDUFA expires every five years and must be reauthorized by Congress. The current version of PDUFA,the fifth reauthorization, or PDUFA V, was renewed as Title I of the FDA Safety and Innovation Act in 2012 and is scheduled to expire in 2017. PDUFA Vfocuses on improving the efficiency and predictability of the review process, strengthening the agency regulatory science base and enhancing benefit-riskassessment and post-approval safety surveillance. The next reauthorization of PDUFA in 2017 may bring changes or additions to regulatory requirements fordrugs and medical devices regulated under the FDCA. In addition, both the U.S. House of Representatives, under the 21st Century Cures bill which passed theHouse in 2015, and the Senate, under several proposals collectively referred to as Innovations for Healthier Americans, are currently considering legislationthat may change regulatory requirements for drugs and medical devices in the future. It is uncertain, however, whether or when any changes or additions toregulatory requirements for drugs or medical devices would be enacted.The approval process is lengthy and difficult and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied. The FDAhas substantial discretion in the product approval process, and it is impossible to predict with any certainty whether and when the FDA will grant marketingapproval. The FDA may on occasion require the sponsor of an NDA to conduct additional clinical studies or to provide other scientific or technicalinformation about the product, and these additional requirements may lead to unanticipated delay or expense. Even if such data and information aresubmitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical studies are not alwaysconclusive, and the FDA may interpret data differently than we interpret the same data.If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use mayotherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings orprecautions be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to further assess adrug product’s safety and effectiveness after NDA approval. The FDA also may impose a Risk Evaluation and Mitigation Strategy, or REMS, to ensure thatthe benefits of a product outweigh its risks. A REMS could add training requirements for healthcare professionals, safety communications efforts and limitson channels of distribution, among other things. The sponsor would be required to evaluate and monitor the various REMS activities and adjust them if needbe. Whether a REMS would be imposed on any of our products and any resulting financial impact is uncertain at this time.Any drug products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product samplingand distribution requirements, complying with certain electronic records and signature requirements, and complying with FDA promotion and advertisingrequirements. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. Drugsmay be promoted only for the approved indications and in accordance with the provisions of the approved label and promotional claims must beappropriately balanced with important safety information and otherwise be adequately substantiated. Further, manufacturers of drugs must continue tocomply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition,changes to the manufacturing process generally require prior FDA approval before being implemented, and other types of changes to the approved product,such as adding new indications and additional labeling claims, are also subject to further FDA review and approval. 21 Table of ContentsDrug product manufacturers and other entities involved in the manufacturing and distribution of approved drugs products are required to register theirestablishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain other agencies forcompliance with cGMP and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing,sterilization, packaging, labeling, storage and shipment of the drug product. Manufacturers must establish validated systems to ensure that products meetspecifications and regulatory standards, and test each product batch or lot prior to its release. In addition, manufacturers of commercial PET products,including radiopharmacies, hospitals and academic medical centers, are required to submit either an NDA or Abbreviated New Drug Application, or ANDA, inorder to produce PET drugs for clinical use, or produce the drugs under an IND.The FDA also regulates the preclinical and clinical testing, design, manufacture, safety, efficacy, labeling, storage, record keeping, sales anddistribution, postmarket adverse event reporting, import/export and advertising and promotion of any medical devices that we distribute pursuant to theFDCA and FDA’s implementing regulations. The Federal Trade Commission shares jurisdiction with the FDA over the promotion and advertising of certainmedical devices. The FDA can also impose restrictions on the sale, distribution or use of medical devices at the time of their clearance or approval, orsubsequent to marketing. Currently, two medical devices, both of which are manufactured by third parties which hold the product clearances, comprise only asmall portion of our revenues.The FDA may withdraw marketing authorization for a pharmaceutical or medical device product if compliance with regulatory standards is notmaintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product may result inrestrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatoryrequirements may result in administrative or judicial actions, such as fines, civil monetary penalties, warning letters, holds on clinical studies, product recallsor seizures, product detention or refusal to permit the import or export of pharmaceuticals or medical device products, refusal to approve pendingapplications or supplements, restrictions on marketing or manufacturing, injunctions, or civil or criminal penalties.Because our operations include nuclear pharmacies and related businesses, such as cyclotron facilities used to produce PET products used indiagnostic medical imaging, we are subject to regulation by the NRC or the departments of health of each state in which we operate and the applicable stateboards of pharmacy. In addition, the FDA is also involved in the regulation of cyclotron facilities where PET products are produced in compliance withcGMP requirements and United States Pharmacopeia requirements for PET drug compounding.Drug laws also are in effect in many of the non-U.S. markets in which we conduct business. These laws range from comprehensive drug approvalrequirements to requests for product data or certifications. In addition, inspection of and controls over manufacturing, as well as monitoring of adverse events,are components of most of these regulatory systems. Most of our business is subject to varying degrees of governmental regulation in the countries in whichwe operate, and the general trend is toward increasingly stringent regulation. The exercise of broad regulatory powers by the FDA continues to result inincreases in the amount of testing and documentation required for approval or clearance of new drugs and devices, all of which add to the expense of productintroduction. Similar trends also are evident in major non-U.S. markets, including Canada, the European Union, Australia and Japan.To assess and facilitate compliance with applicable FDA, the NRC and other state, federal and foreign regulatory requirements, we regularly review ourquality systems to assess their effectiveness and identify areas for improvement. As part of our quality review, we perform assessments of our suppliers of theraw materials that are incorporated into products and conduct quality management reviews designed to inform management of key issues that may affect thequality of our products. From time to time, we may determine that products we manufactured or marketed do not meet our specifications, published standards,such as those issued by the International Standards Organization, or regulatory requirements. When a quality or regulatory issue is identified, 22 Table of Contentswe investigate the issue and take appropriate corrective action, such as withdrawal of the product from the market, correction of the product at the customerlocation, notice to the customer of revised labeling and other actions.Drug Price Competition and Patent Term Restoration Act of 1984The Drug Price Competition and Patent Term Restoration Act of 1984, known as the Hatch-Waxman Act, added two pathways for FDA drug approval.First, the Hatch-Waxman Act permits the FDA to approve ANDAs for generic versions of drugs if the ANDA applicant demonstrates, among other things, thatits product is bioequivalent to the innovator product and provides relevant chemistry, manufacturing and product data. Second, the Hatch-Waxman Actcreated what is known as a Section 505(b)(2) NDA, which requires the same information as a full NDA (known as a Section 505(b)(1) NDA), including fullreports of clinical and preclinical studies but allows some of the information from the reports required for marketing approval to come from studies which theapplicant does not own or have a legal right of reference. A Section 505(b)(2) NDA permits a manufacturer to obtain marketing approval for a drug withoutneeding to conduct or obtain a right of reference for all of the required studies. The Hatch-Waxman Act also provides for: (1) restoration of a portion of aproduct’s patent term that was lost during clinical development and application review by the FDA; and (2) statutory protection, known as exclusivity,against the FDA’s acceptance or approval of certain competitor applications.Patent term extension can compensate for time lost during product development and the regulatory review process by returning up to five years ofpatent life for a patent that covers a new product or its use. This period is generally one-half the time between the effective date of an IND and the submissiondate of an NDA, plus the time between the submission date of an NDA and the approval of that application. Patent term extensions, however, are subject to amaximum extension of five years, and the patent term extension cannot extend the remaining term of a patent beyond a total of 14 years. The application forpatent term extension is subject to approval by the U.S. Patent and Trademark Office in conjunction with the FDA.The Hatch-Waxman Act also provides for a period of statutory protection for new drugs that receive NDA approval from the FDA. If the FDA approves aSection 505(b)(1) NDA for a new drug that is a new chemical entity, meaning that the FDA has not previously approved any other new drug containing anysame active moiety, then the Hatch-Waxman Act prohibits the submission or approval of an ANDA or a Section 505(b)(2) NDA for a period of five years fromthe date of approval of the NDA, except that the FDA may accept an application for review after four years under certain circumstances. The Hatch-WaxmanAct will not prevent the filing or approval of a full NDA, as opposed to an ANDA or Section 505(b)(2) NDA, for any drug, but the competitor would berequired to conduct its own clinical trials, and any use of the drug for which marketing approval is sought could not violate another NDA holder’s patentclaims. The Hatch-Waxman Act provides for a three-year period of exclusivity for an NDA for a new drug containing an active moiety that was previouslyapproved by the FDA, but also includes new clinical data (other than bioavailability and bioequivalence studies) to support an innovation over thepreviously approved drug and those studies were conducted or sponsored by the applicant and were essential to approval of the application. This three-yearexclusivity period does not prohibit the FDA from accepting an application from a third party for a drug with that same innovation, but it does prohibit theFDA from approving that application for the three year period. The three year exclusivity does not prohibit the FDA, with limited exceptions, from approvinggeneric drugs containing the same active ingredient but without the new innovation. 23 Table of ContentsHealthcare Reform Act and Related LawsThe Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the HealthcareReform Act, substantially changes the way in which healthcare is financed by both governmental and private insurers and has a significant impact on thepharmaceutical industry. The Healthcare Reform Act contains a number of provisions that affect coverage and reimbursement of drug products and themedical imaging procedures in which our drug products are used. Key provisions include the following: • significantly increasing the presumed utilization rate for imaging equipment costing $1 million or more in the physician office and free-standingimaging facility setting which reduces the Medicare per procedure medical imaging reimbursement; subsequent legislation further increased thepresumed utilization rate effective January 1, 2014; • increasing drug rebates paid to state Medicaid programs under the Medicaid Drug Rebate Program for brand name prescription drugs andextending those rebates to Medicaid managed care organizations; • imposing a non-deductible annual fee on pharmaceutical manufacturers or importers who sell brand name prescription drugs to specified federalgovernment programs; and • imposing an excise tax on the sale of taxable medical device, to be paid by the entity that manufactures or imports the device: the tax applied toapplicable sales made from January 1, 2013 through December 31, 2015, has been suspended for 2016 and 2017, but is scheduled to be reappliedstarting January 1, 2018.The Healthcare Reform Act also establishes an Independent Payment Advisory Board, or IPAB, to reduce the per capita rate of growth in Medicarespending by proposing changes to Medicare payments if expenditures exceed certain targets. A proposal made by the IPAB must be implemented by CMS,unless Congress adopts a proposal that achieves the necessary savings. IPAB proposals may impact payments for physician and free-standing imagingservices beginning in 2015 and for hospital services beginning in 2020. The threshold for triggering IPAB proposals has not been reached, so no adjustmentswill be made under the IPAB until 2018 (at the earliest).The Healthcare Reform Act also amended the federal self-referral laws, requiring referring physicians to inform patients under certain circumstancesthat the patients may obtain services, including MRI, computed tomography, or CT, PET and certain other diagnostic imaging services, from a provider otherthan that physician, another physician in his or her group practice, or another individual under direct supervision of the physician or another physician in thegroup practice. The referring physician must provide each patient with a written list of other suppliers who furnish those services in the area in which thepatient resides. These new requirements could have the effect of shifting where certain diagnostic medical imaging procedures are performed.In addition, the Budget Control Act of 2011 includes provisions to reduce the federal deficit. The Budget Control Act, as amended, resulted in theimposition of 2% reductions to Medicare (but not Medicaid) payments to providers beginning in April 2013. More recent legislation extends reductionsthrough 2025 and front loads the cuts in 2025 to the first half of the year.The Healthcare Reform Act has been subject to political and judicial challenges. In 2012, the Supreme Court considered the constitutionality of certainprovisions of the law. The Supreme Court upheld as constitutional the mandate for individuals to obtain health insurance, but held the provision allowingthe federal government to withhold certain Medicaid funds to states that do not expand state Medicaid programs unconstitutional. Therefore, not all stateshave expanded their Medicaid programs under the Healthcare Reform Act. Political and judicial challenges to the law have continued in the wake of theCourt’s ruling. 24 Table of ContentsHealthcare Fraud and Abuse LawsWe are subject to various federal, state and local laws targeting fraud and abuse in the healthcare industry, including anti-kickback and false claimslaws. Violations of fraud and abuse laws may be punishable by crime or civil sanctions, including fines and civil monetary penalties, and/or exclusion fromfederal health care programs (including Medicare and Medicaid). Federal and state authorities are paying increased attention to enforcement of these lawswithin the pharmaceutical industry, and private individuals have been active in alleging violations of the laws and brining suits on behalf of the governmentunder the federal False Claims Act, or FCA. Violations of international fraud and abuse laws could result in similar penalties, including exclusion fromparticipation in health programs outside the United States. If we were subject to allegations concerning, or were convicted of violating, these laws, ourbusiness could be harmed.The federal Anti-Kickback Statute generally prohibits, among other things, a pharmaceutical manufacturer from directly or indirectly soliciting,offering, receiving, or paying any remuneration in cash or in kind where one purpose is either to induce the referral of an individual for, or the purchase orprescription of a particular drug that is payable by a federal health care program, including Medicare or Medicaid. Violations of the federal Anti-KickbackStatute can result in exclusion from Medicare, Medicaid or other governmental programs as well as civil and criminal fines and penalties of up to $50,000 perviolation and three times the amount of the unlawful remuneration. The majority of states also have anti-kickback, false claims, and similar fraud and abuselaws and although the specific provisions of these laws vary, their scope is generally broad, and there may not be regulations, guidance or court decisions thatapply the laws to particular industry practices. There is therefore a possibility that our practices might be challenged under the anti-kickback statutes orsimilar laws.Federal and state false claims laws generally prohibit anyone from knowingly and willingly, among other activities, presenting, or causing to bepresented for payment to third party payors (including Medicare and Medicaid) claims for drugs or services that are false or fraudulent (which may includeclaims for services not provided as claimed or claims for medically unnecessary services). False or fraudulent claims for purposes of the FCA carry fines andcivil penalties for violations ranging from $5,500 to $11,000 for each false claim, plus up to three times the amount of damages sustained by the federalgovernment and, most critically, may provide the basis for exclusion from federally funded healthcare programs. There is also a criminal FCA statute bywhich individuals or entities that submit false claims can face criminal penalties. In addition, under the federal Civil Monetary Penalty Law, the Departmentof Health and Human Services Office of Inspector General has the authority to exclude from participation in federal health care programs or to impose civilpenalties against any person who, among other things, knowingly presents, or causes to be presented, certain false or otherwise improper claims. Ouractivities relating to the sale and marketing of our products may be subject to scrutiny under these laws.Laws and regulations have also been enacted by the federal government and various states to regulate the sales and marketing practices ofpharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers; requirepharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidancepromulgated by the U.S. federal government; and/or require disclosure to the government and/or public of financial interactions (so-called “sunshine laws”).Recent scrutiny of pharmaceutical pricing practices by certain companies may lead to changes in laws that currently allow substantial flexibility in pricingdecisions by pharmaceutical manufacturers. Such changes could occur at the federal level or state level and may be adopted by statute, rule, or sub-regulatorypolicies. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures. Many of these laws and regulationscontain ambiguous requirements or require administrative guidance for implementation. Given the lack of clarity in laws and their implementation, ourreporting actions could be subject to the penalty provisions of the pertinent federal and state laws and regulations. 25 Table of ContentsOther Healthcare LawsOur operations may be affected by the Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health InformationTechnology for Economic and Clinical Health Act and its implementing regulations, or HITECH, which impose obligations on certain “covered entities”(healthcare providers, health plans and healthcare clearinghouses) and certain of their “business associate” contractors with respect to safeguarding theprivacy, security and transmission of individually identifiable health information. Although we believe that we are neither a “covered entity” nor a “businessassociate” under the legislation, a business associate relationship may be imputed from facts and circumstances even in the absence of an actual businessassociate agreement. In addition, HIPAA and HITECH may affect our interactions with customers who are covered entities or their business associates.Laws Relating to Foreign TradeWe are subject to various federal and foreign laws that govern our international business practices with respect to payments to government officials.Those laws include the Foreign Corrupt Practices Act, or FCPA, which prohibits U.S. companies and their representatives from paying, offering to pay,promising, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or politicalcandidate for the purpose of obtaining or retaining business or to otherwise obtain favorable treatment or influence a person working in an official capacity.In many countries, the healthcare professionals we regularly interact with may meet the FCPA’s definition of a foreign government official. The FCPA alsorequires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequatesystem of internal accounting controls.Those laws also include the U.K. Bribery Act, or the Bribery Act, which proscribes giving and receiving bribes in the public and private sectors, bribinga foreign public official, and failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conductbusiness in the United Kingdom generally will be subject to the Bribery Act. Penalties under the Bribery Act include potentially unlimited fines forcompanies and criminal sanctions for corporate officers under certain circumstances.Our policies mandate compliance with these anti-bribery laws. Our operations reach many parts of the world that have experienced governmentalcorruption to some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite ourtraining and compliance programs, our internal control policies and procedures may not always protect us from reckless or criminal acts committed by ouremployees or agents.Health and Safety LawsWe are also subject to various federal, state and local laws, regulations and recommendations, both in the United States and abroad, relating to safeworking conditions, laboratory and manufacturing practices and the use, transportation and disposal of hazardous or potentially hazardous substances.Environmental MattersWe are subject to various federal, state and local laws and regulations relating to the protection of the environment, human health and safety in theUnited States and in other jurisdictions in which we operate. Our operations, like those of other medical product companies, involve the transport, use,handling, storage, exposure to and disposal of materials and wastes regulated under environmental laws, including hazardous and radioactive materials andwastes. If we violate these laws and regulations, we could be fined, criminally charged or otherwise sanctioned by regulators. We believe that our operationscurrently comply in all material respects with applicable environmental laws and regulations. See “Item 1A—Risk Factors—We use hazardous materials inour business and must comply with environmental laws and regulations, which can be expensive.” 26 Table of ContentsCertain environmental laws and regulations assess liability on current or previous owners or operators of real property for the cost of investigation,removal or remediation of hazardous materials or wastes at those formerly owned or operated properties or at third party properties at which they havedisposed of hazardous materials or wastes. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury,property damage or other claims due to the presence of, or exposure to, hazardous materials or wastes. We currently are not party to any claims or anyobligations to investigate or remediate contamination at any of our facilities.We are required to maintain a number of environmental permits and nuclear licenses for our North Billerica facility, which is our primarymanufacturing, packaging and distribution facility. In particular, we must maintain a nuclear byproducts materials license issued by the Commonwealth ofMassachusetts. This license requires that we provide financial assurance demonstrating our ability to cover the cost of decommissioning anddecontaminating, or D&D, the Billerica site at the end of its use as a nuclear facility. As of December 31, 2015, we currently estimate the D&D cost at theBillerica site to be approximately $26.2 million. As of December 31, 2015 and 2014, we have a liability recorded associated with the fair value of the assetretirement obligations of approximately $8.1 million and $7.4 million, respectively. We have recorded accretion expense of $0.7 million, $0.8 million and$0.6 million during the years ended December 31, 2015, 2014 and 2013, respectively. We currently provide this financial assurance in the form of suretybonds. We generally contract with third parties for the disposal of wastes generated by our operations. Prior to disposal, we store any low level radioactivewaste at our facilities until the materials are no longer considered radioactive, as allowed by our licenses and permits.Environmental laws and regulations are complex, change frequently and have become more stringent over time. While we have budgeted for futurecapital and operating expenditures to maintain compliance with these laws and regulations, we cannot assure you that our costs of complying with current orfuture environmental protection, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations andfinancial condition. Further, we cannot assure you that we will not be subject to additional environmental claims for personal injury or cleanup in the futurebased on our past, present or future business activities. While it is not feasible to predict the future costs of ongoing environmental compliance, it is possiblethat there will be a need for future provisions for environmental costs that, in management’s opinion, are not likely to have a material effect on our financialcondition, but could be material to the results of operations in any one accounting period.EmployeesAs of January 31, 2016, we had 474 employees, of which 406 were located in the United States and 68 were located internationally, and approximately5 contractors. None of our employees are represented by a collective bargaining unit, and we believe that our relationship with our employees is good.Corporate HistoryFounded in 1956 as New England Nuclear Corporation, our medical imaging diagnostic business was purchased by DuPont in 1981. BMSsubsequently acquired our diagnostic medical imaging business as part of its acquisition of DuPont Pharmaceuticals in 2001. Avista acquired our medicalimaging business from BMS in January 2008. On June 30, 2015, the Company completed an initial public offering, or IPO, of its common stock at a price tothe public of $6.00 per share. The Company’s common stock is now traded on the NASDAQ under the symbol “LNTH”.Available informationThe Company maintains a global internet site at www.lantheus.com.

XBRL is an electronic coding language to create an interactive financialstatement data over the internet. The information on the Company’s website is neither part of nor incorporated by reference in this Annual Report on Form10-K.Item 1A. Risk FactorsYou should carefully consider the following risks. These risks could materially affect our business, results of operations or financial condition, causethe trading price of our outstanding notes to decline materially or cause our actual results to differ materially from those expected or those expressed in anyforward-looking statements made by us or on our behalf. See “Cautionary Note Regarding Forward-Looking Statements” and the risks of our businessesdescribed elsewhere in this annual report.Our dependence upon third parties for the manufacture and supply of a substantial portion of our products could prevent us from delivering ourproducts to our customers in the required quantities, within the required timeframes, or at all, which could result in order cancellations and decreasedrevenues.We obtain a substantial portion of our products from third party manufacturers and suppliers. We rely on JHS as our sole source manufacturer ofDEFINITY, Neurolite and evacuation vials. We currently have additional ongoing technology transfer activities at JHS for our Cardiolite products and atPharmalucence for DEFINITY, but we can give no assurances as to when that technology transfer will be completed and when we will actually receive supplyof Cardiolite from JHS or DEFINITY from Pharmalucence. In the meantime, our DEFINITY, Neurolite, evacuation vial, saline and Cardiolite product supply iscurrently approved for manufacture by a single manufacturer. In addition, we have no manufacturer for Ablavar.Based on our current estimates, we believe that we will have sufficient supply of DEFINITY, Neurolite and evacuation vials from JHS to meet expecteddemand and sufficient supply of saline from our sole manufacturer. We also believe that we will have sufficient Cardiolite product supply from our currentsupplier and from JHS to meet expected demand when the technology transfer process is completed and we have obtained regulatory approval for thismanufacturing site. However, we can give no assurances that JHS or our other manufacturing partners will be able to manufacture and distribute our productsin a high quality and timely manner and in sufficient quantities to allow us to avoid product stock-outs and shortfalls. Currently, the regulatory authorities incertain countries have not yet approved JHS as a manufacturer of our products. Accordingly, until those regulatory approvals have been obtained, ourinternational business, results of operations, financial condition and cash flows will continue to be adversely affected.Our manufacturing agreement for Ablavar has terminated. We do not have any current plans to initiate technology transfer activities for Ablavar. Ourexisting Ablavar inventory will expire in the third quarter of 2016, and we will have no further Ablavar inventory that we will be able to sell unless and untilwe engage in Ablavar technology transfer activities in the future with a new manufacturing partner.In addition to the products described above, for reasons of quality assurance or cost-effectiveness, we purchase certain components and raw materialsfrom sole suppliers (including, for example, the lead casing for our TechneLite generators, the evacuation vials for our TechneLite generators manufacturedby JHS and the lipid blend material used in the processing of DEFINITY). Because we do not control the actual production of many of the products we selland many of the raw materials and components that make up the products we sell, we may be subject to delays caused by interruption in production based onevents and conditions outside of our control. At our North Billerica, Massachusetts facility, we manufacture TechneLite on a relatively new, highlyautomated production line, as well as Thallium and Gallium using our older cyclotron technology and Xenon using our hot cell infrastructure. As with allmanufacturing facilities, equipment and infrastructure age and become subject to 28 Table of Contentsincreasing maintenance and repair. If we or one of our manufacturing partners experiences an event, including a labor dispute, natural disaster, fire, poweroutage, machinery breakdown, security problem, failure to meet regulatory requirements, product quality issue, technology transfer issue or other issue, wemay be unable to manufacture the relevant products at previous levels or on the forecasted schedule, if at all. Due to the stringent regulations andrequirements of the governing regulatory authorities regarding the manufacture of our products, we may not be able to quickly restart manufacturing at athird party or our own facility or establish additional or replacement sources for certain products, components or materials.In addition to our existing manufacturing relationships, we are also pursuing new manufacturing relationships to establish and secure additional oralternative suppliers for our commercial products. On November 12, 2013, we entered into a Manufacturing and Supply Agreement with Pharmalucence tomanufacture and supply DEFINITY. We cannot assure you, however, that these supply diversification activities will be successful, or that before thosealternate manufacturers or sources of product are fully functional and qualified, that we will be able to avoid or mitigate interim supply shortages. In addition,we cannot assure you that our existing manufacturers or suppliers or any new manufacturers or suppliers can adequately maintain either their financial healthor regulatory compliance to allow continued production and supply. A reduction or interruption in manufacturing, or an inability to secure alternativesources of raw materials or components, could eventually have a material adverse effect on our business, results of operations, financial condition and cashflows.Challenges with product quality or product performance, including defects, caused by us or our suppliers could result in a decrease in customers andsales, unexpected expenses and loss of market share.The manufacture of our products is highly exacting and complex and must meet stringent quality requirements, due in part to strict regulatoryrequirements, including the FDA’s current cGMPs. Problems may be identified or arise during manufacturing quality review, packaging or shipment for avariety of reasons including equipment malfunction, failure to follow specific protocols and procedures, defective raw materials and environmental factors.Additionally, manufacturing flaws, component failures, design defects, off-label uses or inadequate disclosure of product-related information could result inan unsafe condition or the injury or death of a patient. Those events could lead to a recall of, or issuance of a safety alert relating to, our products. We alsomay undertake voluntarily to recall products or temporarily shutdown production lines based on internal safety and quality monitoring and testing data.Quality, regulatory and recall challenges could cause us to incur significant costs, including costs to replace products, lost revenue, damage tocustomer relationships, time and expense spent investigating the cause and costs of any possible settlements or judgments related thereto and potentiallycause similar losses with respect to other products. These challenges could also divert the attention of our management and employees from operational,commercial or other business efforts. If we deliver products with defects, or if there is a perception that our products or the processes related to our productscontain errors or defects, we could incur additional recall and product liability costs, and our credibility and the market acceptance and sales of our productscould be materially adversely affected. Due to the strong name recognition of our brands, an adverse event involving one of our products could result inreduced market acceptance and demand for all products within that brand, and could harm our reputation and our ability to market our products in the future.In some circumstances, adverse events arising from or associated with the design, manufacture or marketing of our products could result in the suspension ordelay of regulatory reviews of our applications for new product approvals. These challenges could have a material adverse effect on our business, results ofoperations, financial condition and cash flows. 29 Table of ContentsThe global supply of Moly is fragile and not stable. Our dependence on a limited number of third party suppliers for Moly could prevent us fromdelivering some of our products to our customers in the required quantities, within the required timeframe, or at all, which could result in ordercancellations and decreased revenues.A critical ingredient of TechneLite, historically our largest product by annual revenues, is Moly. We currently purchase finished Moly from four of thefive main processing sites in the world, namely ANSTO in Australia; IRE in Belgium; Nordion, formerly known as MDS Nordion, in Canada; and NTP inSouth Africa. These processing sites are, in turn, supplied by six of the seven main Moly-producing reactors in the world, namely, OPAL in Australia; BR2 inBelgium; LVR-10 in the Czech Republic; HFR in The Netherlands; NRU in Canada; and SAFARI in South Africa.Historically, our largest supplier of Moly has been Nordion, which has relied on the NRU reactor owned by Atomic Energy of Canada Limited, orAECL, a Crown corporation of the Government of Canada, located in Chalk River, Ontario. This reactor was off-line from May 2009 until August 2010 dueto a heavy water leak in the reactor vessel. The inability of the NRU reactor to produce Moly and of Nordion to finish Moly during the shutdown period had adetrimental effect on our business, results of operations and cash flows. As a result of the NRU reactor shutdown, we experienced business interruption losses.We estimate the quantity of those losses to be, in the aggregate, more than $70 million, including increases in the cost of obtaining limited amounts of Molyfrom alternate, more distant, suppliers and substantial decreases in revenue as a result of significantly curtailed manufacturing of TechneLite generators andour decreased ability to sell other Moly-based medical imaging products, including Cardiolite, in comparison to our forecasted results. The Government ofCanada has stated that it intends to exit the medical isotope business when the NRU reactor’s current license transitions in October 2016 and thereafterprovide only emergency back-up medical isotope supply through March 2018.Starting in 2011, the NRU reactor has been shut down for at least four weeks at least once a year for inspection and maintenance. The most recentshutdown period ran from April 13, 2015 until May 13, 2015, and we were able to source sufficient Moly to satisfy all of our standing-order customer demandfor our TechneLite generators during this time period from our other suppliers. During this shutdown period, however, because Xenon is a by-product of theMoly production process and is currently captured only by NRU, we were not able to supply all of our standing-order customer demand for Xenon for anapproximately two week period. There can be no assurance that in the future these off-line periods will last for the stated time or that the NRU will notexperience other unscheduled shutdowns. Further prolonged scheduled or unscheduled shutdowns would limit the amount of Moly and Xenon available tous and limit the quantity of TechneLite that we could manufacture, sell and distribute and the amount of Xenon that we could sell and distribute, resulting ina further substantial negative effect on our business, results of operations, financial condition and cash flows.In the face of the NRU reactor operating challenges and licensure issues, we entered into Moly supply agreements with NTP, ANSTO and IRE toaugment our supply of Moly. ANSTO has under construction, in cooperation with NTP, a new Moly processing facility that ANSTO believes will expand itsproduction capacity by approximately 2.5 times, with expanded commercial production planned to start in the latter part of 2016. In addition, IRE recentlyreceived approval from its regulator to expand its production capability by up to 50% of its former capacity. This new ANSTO and IRE production capacityis expected to replace the NRU’s current routine production. While we believe this additional Moly supply now gives us the most balanced and diversifiedMoly supply chain in the industry, a prolonged disruption of service from only one of our significant Moly suppliers could have a material adverse effect onour business, results of operations, financial condition and cash flows. We are also pursuing additional sources of Moly from potential new producers aroundthe world to further augment our current supply. In November 2014, we announced entering into a new strategic agreement with SHINE for the future supplyof Moly. Under the terms of the supply agreement, SHINE will provide Moly produced using its proprietary LEU-solution technology for use in ourTechneLite generators once SHINE’s facility becomes operational and receives all necessary regulatory approvals, which SHINE currently estimates willoccur in 2019. However, we cannot assure you that SHINE or any other possible additional sources of Moly 30 Table of Contentswill result in commercial quantities of Moly for our business, or that these new suppliers together with our current suppliers will be able to deliver a sufficientquantity of Moly to meet our needs.U.S., Canadian and international governments have encouraged the development of a number of alternative Moly production projects with existingreactors and technologies as well as new technologies. However, the Moly produced from these projects will likely not become available until after the NRUreactor‘s transition in 2016 from providing regular supply of medical isotopes to providing only emergency back-up supply of HEU based medical isotopesthrough March 2018. As a result, there is a limited amount of Moly available which could limit the quantity of TechneLite that we could manufacture, selland distribute, resulting in a further substantial negative effect on our business, results of operations, financial condition and cash flows.Most of the global suppliers of Moly rely on AREVA Group in France to fabricate uranium targets and in some cases fuel for research reactors fromwhich Moly is produced. Absent a new supplier, a supply disruption relating to uranium targets or fuel could have a substantial negative effect on ourbusiness, results of operations, financial condition and cash flows.The instability of the global supply of Moly, including supply shortages, resulted in increases in the cost of Moly, which has negatively affected ourmargins, and more restrictive agreements with suppliers, which could further increase our costs.With the general instability in the global supply of Moly, including supply shortages during 2009 and 2010, we have faced substantial increases in thecost of Moly in comparison to historical costs. We expect these cost increases to continue in the future as the Moly suppliers move closer to a full costrecovery business model. The Organization of Economic Cooperation and Development, or OECD, defines full cost recovery as the identification of all of thecosts of production and recovering these costs from the market. While we are generally able to pass Moly cost increases on to our customers in our customercontracts, if we are not able to do so in the future, our margins may decline further with respect to our TechneLite generators, which could have a materialadverse effect on our business, results of operations, financial condition and cash flows.The Moly supply shortage caused by the 2009-10 NRU reactor shutdown has had a negative effect on the demand for some of our products, which willlikely continue in the future.The Moly supply shortage also had a negative effect on the use of other technetium generator-based diagnostic medical imaging agents, including ourCardiolite products. With less Moly, we manufactured fewer generators for radiopharmacies and hospitals to make up unit doses of Cardiolite products,resulting in decreased market share of Cardiolite products in favor of Thallium, an older medical isotope that does not require Moly, and other diagnosticmodalities. With the return to service of the NRU reactor, we have seen increased sales of TechneLite. However, TechneLite unit volume has not returned topre-shortage levels for, we believe, a number of reasons, including: (i) changing staffing and utilization practices in radiopharmacies, which have resulted inan increased number of unit-doses of technetium-based radiopharmaceuticals being made from available amounts of technetium; (ii) shifts to alternativediagnostic imaging modalities during the Moly supply shortage, which have not returned to technetium-based procedures; and (iii) decreased amounts oftechnetium being used in unit-doses of technetium-based radiopharmaceuticals due to growing concerns about patient radiation dose exposure. We do notknow if the staffing and utilization practices in radiopharmacies, the mix between technetium and non-technetium-based diagnostic procedures and theincreased concerns about radiation exposure, will allow technetium demand to ever return to pre-shortage levels, which could have a material adverse effecton our business, results of operations, financial condition and cash flows. 31 Table of ContentsOur just-in-time manufacturing of radiopharmaceutical products relies on the timely receipt of radioactive raw materials and the timely shipment offinished goods, and any disruption of our supply or distribution networks could have a negative effect on our business.Because a number of our radiopharmaceutical products, including our TechneLite generators, rely on radioisotopes with limited half-lives, we mustmanufacture, finish and distribute these products on a just-in-time basis, because the underlying radioisotope is in a constant state of radio decay. Forexample, if we receive Moly in the morning of a manufacturing day for TechneLite generators, then we will generally ship finished generators to customersby the end of that same business day. Shipment of generators may be by next day delivery services or by either ground or air custom logistics. Any delay inus receiving radioisotopes from suppliers or being able to have finished products delivered to customers because of weather or other unforeseentransportation issues could have a negative effect on our business, results of operations, financial condition and cash flows.The growth of our business is substantially dependent on increased market penetration for the appropriate use of DEFINITY in suboptimalechocardiograms.The growth of our business is substantially dependent on increased market penetration for the appropriate use of DEFINITY in suboptimalechocardiograms. Of the total number of echocardiograms performed each year in the United States—over 31 million in 2015—based on medical literature, athird party source estimates that 20%, or approximately 6 million echocardiograms in 2015, produce suboptimal images. We estimate that DEFINITY hadapproximately 78% share of the market for contrast agents in echocardiography procedures in which a contrast agent is used in the United States as ofDecember 2015. If we are not able to continue to grow DEFINITY sales through increased market penetration, we will not be able to grow the revenue andcash flow of the business or share the substantial overhead of the balance of our business, which could have a negative effect on our prospects.We face potential supply and demand challenges for Xenon.Currently, Nordion is our sole supplier, and we believe the principal supplier on a global basis, of Xenon, which is captured by Nordion as a by-productof the Moly production process. In January 2015, we entered into a new strategic agreement with IRE for the future supply of Xenon. Under the terms of theagreement, IRE will provide bulk Xenon to us for processing and finishing once development work has been completed and all necessary regulatoryapprovals have been obtained. We currently estimate commercial production will occur in 2016. If we are not able to begin providing commercial quantitiesof Xenon prior to the NRU reactor’s transition in October 2016 from providing regular supply of medical isotopes to providing only emergency back-upsupply of HEU based medical isotopes through March 2018, there may be a period of time during which we are not able to offer Xenon in our portfolio ofcommercial products, which would have a negative effect on our business, results of operations, financial condition and cash flows. For the year endedDecember 31, 2015, Xenon represented approximately 17% of our revenues.Currently, we obtain Xenon from Nordion on a purchase order basis. If we are not able to pass along to our customers any change of terms from oursupplier, there could be a negative effect on our business, results of operations, financial condition and cash flows.Currently, we are the only supplier of packaged Xenon in the U.S., although historically several companies also sold packaged Xenon as a pulmonaryimaging agent in the U.S. We understand that a radiopharmaceutical manufacturer is now seeking regulatory approval from the FDA to sell packaged Xenonin the U.S. If that manufacturer receives FDA approval and begins to sell packaged Xenon in the U.S., depending upon the pricing, extent of availability andmarket penetration of the new offering, we believe we are at risk for volume loss and price erosion for those customers which are not subject to price orvolume commitments. See “Part II, Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key FactorsAffecting Our Results—Competition for Xenon.” 32 Table of ContentsIn addition to a possible new supplier of packaged Xenon in the U.S., if there is an increase in the use of other imaging modalities in place of packagedXenon, our current sales volumes would decrease, which could have a negative effect on our business, results of operations, financial condition and cashflows.Xenon is frequently administered as part of a ventilation scan to evaluate pulmonary function prior to a perfusion scan with microaggregated albumin,or MAA, a technetium-based radiopharmaceutical used to evaluate blood flow to the lungs. Currently, Draxis is the sole supplier of MAA on a global basis. In2014, Draxis announced substantial price increases for MAA. The increased price of MAA, or difficulties in obtaining MAA, could decrease the frequency inwhich MAA is used for lung perfusion evaluation, in turn, decreasing the frequency that Xenon is used for pulmonary function evaluation, resulting in anegative effect on our business, results of operations, financial condition and cash flows.In the United States, we are heavily dependent on a few large customers and group purchasing organization arrangements to generate a majority of ourrevenues for our medical imaging products. Outside of the United States, we rely on distributors to generate a substantial portion of our revenue.In the United States, we have historically relied on a limited number of radiopharmacy customers, primarily Cardinal, GE Healthcare, UPPI and Triad,to distribute our current largest volume nuclear imaging products and generate a majority of our revenues. Three customers accounted for approximately 33%of our revenues in the fiscal year ended December 31, 2015, with UPPI, Cardinal, and GE Healthcare accounting for approximately 12%, 11% and 10%,respectively. Among the existing radiopharmacies in the United States, continued consolidations, divestitures and reorganizations may have a negative effecton our business, results of operations, financial condition or cash flows. We generally have distribution arrangements with our major radiopharmacycustomers pursuant to multi-year contracts, each of which is subject to renewal. If these contracts are terminated prior to expiration of their term, or are notrenewed, or are renewed on terms that are less favorable to us, then such an event could have a material adverse effect on our business, results of operations,financial condition and cash flows.For both our nuclear imaging agents and contrast agents, we continue to experience significant pricing pressures from our competitors, large customersand group purchasing organizations, and any significant, additional pricing pressures could lead to a reduction in revenue which could have a materialadverse effect on our business, results of operations, financial condition and cash flows.Outside of the United States, Canada, Australia and Puerto Rico, we have no radiopharmacies or sales force and, consequently, rely on third partydistributors, either on a country-by-country basis or on a multicountry, regional basis, to market, sell and distribute our products. These distributorsaccounted for approximately 15%, 17% and 13% of non-U.S. revenues for the fiscal years ended December 31, 2015, 2014 and 2013, respectively. In certaincircumstances, these distributors may also sell competing products to our own or products for competing diagnostic modalities and may have incentives toshift sales towards those competing products. As a result, we cannot assure you that our international distributors will increase or maintain our current levelsof unit sales or increase or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, results of operations,financial condition and cash flows.We have a history of net losses and total stockholder’s deficits which may continue and which may negatively impact our ability to achieve or sustainprofitability.We have a history of net losses and cannot assure you that we will achieve or sustain profitability in the future. We incurred net losses for the yearsended December 31, 2015, 2014 and 2013 of $14.7 million, $3.6 million and $61.6 million, respectively, and as of December 31, 2015, we had a totalstockholders’ deficit of $185.3 million. We cannot assure you that we will be able to achieve or sustain profitability on a quarterly or annual basis in thefuture. If we cannot improve our profitability, the value of our enterprise may decline. 33 Table of ContentsWe face significant competition in our business and may not be able to compete effectively.The market for diagnostic medical imaging agents is highly competitive and continually evolving. Our principal competitors in existing diagnosticmodalities include large, global companies with substantial financial, manufacturing, sales and marketing and logistics resources that are more diversifiedthan ours, such as GE Healthcare, Bracco, Mallinckrodt, Bayer and Draxis, as well as other competitors. We cannot anticipate their actions in the same orcompeting diagnostic modalities, such as significant price reductions on products that are comparable to our own, development or introduction of newproducts that are more cost-effective or have superior performance than our current products, the introduction of generic versions when our proprietaryproducts lose their patent protection or the new entry into a generic market in which we are already a participant. In addition, distributors of our productscould attempt to shift end-users to competing diagnostic modalities and products. Our current or future products could be rendered obsolete or uneconomicalas a result of these activities. Our failure to compete effectively could cause us to lose market share to our competitors and have a material adverse effect onour business, results of operations, financial condition and cash flows.In October 2014, Bracco received FDA approval in the United States for its echocardiography agent, Lumason (known as SonoVue outside of the U.S.),which is already approved for sale in Europe and certain Asian markets, including China, Japan and Korea. Bracco now has one of three FDA-approvedechocardiography contrast agents in the United States, together with GE Healthcare’s Optison and our DEFINITY. If Bracco successfully commercializesLumason in the United States without otherwise increasing the overall usage of ultrasound contrast agents, our current and future sales volume could suffer,which would have a material adverse effect on our business, results of operations, financial condition and cash flows.Xenon for lung ventilation diagnosis is our third largest product by revenue. Historically, several companies sold packaged Xenon as a pulmonaryimaging agent in the U.S., but since 2010 we have been the only supplier of this imaging agent in the U.S. We understand that a radiopharmaceuticalmanufacturer is now seeking regulatory approval from the FDA to sell packaged Xenon in the U.S. If that manufacturer receives FDA approval and begins tosell packaged Xenon in the U.S., depending upon the pricing, extent of availability and market penetration of the new offering, we believe we are at risk forvolume loss and price erosion for those customers which are not subject to price or volume commitments. See “Part II, Item 7—Management’s Discussion andAnalysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—Competition for Xenon.”Certain of our customers are highly dependent on payments from third party payors, including government sponsored programs, particularly Medicare,in the United States and other countries in which we operate, and reductions in third party coverage and reimbursement rates for our products (orsources provided with our products) could adversely affect our business and results of operations.A substantial portion of our revenue depends, in part, on the extent to which the costs of our products purchased by our customers are reimbursed bythird party payors, including Medicare, Medicaid, other U.S. government sponsored programs, non-U.S. governmental payors and private payors. These thirdparty payors exercise significant control over patient access and increasingly use their enhanced bargaining power to secure discounted rates and otherrequirements that may reduce demand for our products. Our potential customers’ ability to obtain appropriate reimbursement for products and services fromthese third party payors affects the selection of products they purchase and the prices they are willing to pay. For example, certain radiopharmaceuticals,when used for non-invasive imaging of the perfusion of the heart for the diagnosis and management of patients with known or suspected coronary arterydisease, are currently subject to a Medicare National Coverage Determination, or NCD. The NCD permits the coverage of such radiopharmaceuticals onlywhen certain criteria are met. Our pipeline products, including flurpiridaz F 18, if approved, may become subject to this NCD, and may not be covered at all.If Medicare and other third party payors do not provide appropriate reimbursement for the costs of our products (or services provided using our products),deny the coverage of the products (or those services), or reduce current levels of reimbursement, healthcare professionals may not 34 Table of Contentsprescribe our products and providers and suppliers may not purchase our products. In addition, demand for new products may be limited unless we obtainfavorable reimbursement policies (including coverage, coding and payment) from governmental and private third party payors at the time of the product’sintroduction, which will depend, in part, on our ability to demonstrate that a new agent has a positive impact on clinical outcomes. Third party payorscontinually review their coverage policies for existing and new therapies and can deny coverage for treatments that include the use of our products or revisepayment policies such that payments do not adequately cover the cost of our products. Even if third party payors make coverage and reimbursementavailable, that reimbursement may not be adequate or these payors’ reimbursement policies may have an adverse effect on our business, results of operations,financial condition and cash flows.Over the past several years, Medicare has implemented numerous changes to payment policies for imaging procedures in both the hospital setting andnon-hospital settings (which include physician offices and freestanding imaging facilities). Some of these changes have had a negative impact on utilizationof imaging services. Examples of these changes include: • limiting payments for imaging services in physician offices and free-standing imaging facility settings based upon rates paid to hospitaloutpatient departments; • reducing payments for certain imaging procedures when performed together with other imaging procedures in the same family of procedures onthe same patient on the same day in the physician office and free-standing imaging facility setting; • making significant revisions to the methodology for determining the practice expense component of the Medicare payment applicable to thephysician office and free-standing imaging facility setting which results in a reduction in payment; and • revising payment policies and reducing payment amounts for imaging procedures performed in the hospital outpatient setting.In the physician office and free-standing imaging facility setting, services provided using our products are reimbursed under the Medicare physicianfee schedule and, in April 2015, new legislation changed the methodology for updating the fee schedule. The Medicare physician fee schedule is no longersubject to mandatory cuts under Medicare’s sustainable growth rate formula (which was intended to limit the increase in aggregate physician payments).Payments under the Medicare physician fee schedule are now subject to specific annual updates (0.5%) through 2019; no updates from 2020 to 2025; and,beginning in 2026, differential updates based on whether the physician participates in alternative payment models (with 0.75% updates for participants and0.25% updates for non-participants). The legislation also adjusts the fee schedule payments, beginning in 2019, for certain physicians based on theirperformance under a consolidated measurement system (that measures performance with respect to quality, resource utilization, meaningful use of certifiedelectronic health records technology, and clinical practice improvement activities). Also beginning in 2019, physicians may be eligible for a bonus based onthe use of alternative payment models. The impact of these changes cannot be determined at this time.We believe that Medicare changes to payment policies for imaging procedures applicable to non-hospital settings will continue to result in certainphysician practices ceasing to provide these services and a further shifting of where certain medical imaging procedures are performed, from the physicianoffice and free-standing imaging facility settings to the hospital outpatient setting. Changes applicable to Medicare payment in the hospital outpatientsetting could also influence the decisions by hospital outpatient physicians to perform procedures that involve our products. Within the hospital outpatientsetting, CMS has revised its payment policy such that the use of many of our products is not separately payable by Medicare, although other products may bepayable as an addition to the procedure. Specifically, since 2013, although Medicare generally does not provide separate payment to hospitals for the use ofdiagnostic radiopharmaceuticals administered in an outpatient setting, CMS has had a policy to make an additional payment to hospitals that utilizeproducts with non-HEU, meaning the product is 95% derived from non-HEU sources. This payment policy continues in 2016. Although 35 Table of Contentssome of our TechneLite generators are manufactured using non-HEU, not all of our TechneLite generators meet CMS’s definition of non-HEU, and thereforethis payment is not be available for doses produced by the latter category of TechneLite generators used by our customers. This payment as well as otherchanges to the Medicare hospital outpatient prospective payment system payment rates could influence the decisions by hospital outpatient physicians toperform procedures that involve our products.We also believe that all these changes and their resulting pressures may incrementally reduce the overall number of diagnostic medical imagingprocedures performed. These changes overall could slow the acceptance and introduction of next-generation imaging equipment into the marketplace, which,in turn, could adversely impact the future market adoption of certain of our imaging agents already in the market or currently in clinical or preclinicaldevelopment. We expect that there will continue to be proposals to reduce or limit Medicare and Medicaid payment for diagnostic services.We also expect increased regulation and oversight of advanced diagnostic testing in which our products are used. Recent federal legislation requiresCMS to develop appropriate use criteria, or AUC, that professionals must consult when ordering advanced diagnostic imaging services (which include MRI,CT, nuclear medicine (including PET) and other advanced diagnostic imaging services that the Secretary of HHS, may specify). Beginning in 2017, paymentwill be made to the furnishing professional for an applicable advanced diagnostic imaging service only if the claim indicates that the ordering professionalconsulted a qualified clinical decision support mechanism, as identified by HHS, as to whether the ordered service adheres to the applicable AUC. To theextent that these types of changes have the effect of reducing the aggregate number of diagnostic medical imaging procedures performed in the United States,our business, results of operations, financial condition and cash flows would be adversely affected. See “Business—Regulatory Matters.”Reforms to the United States healthcare system may adversely affect our business.A significant portion of our patient volume is derived from U.S. government healthcare programs, principally Medicare, which are highly regulated andsubject to frequent and substantial changes. For example, in March 2010, the President signed one of the most significant healthcare reform measures indecades, the Patient Protection and Affordable Care Act, as amended by the Healthcare Reform Act. The Healthcare Reform Act substantially changed theway healthcare is financed by both governmental and private insurers. The law contains a number of provisions that affect coverage and reimbursement ofdrug products and medical imaging procedures in which our drug products are used and/or that could potentially reduce the aggregate number of diagnosticmedical imaging procedures performed in the United States. See “Business—Regulatory Matters—Healthcare Reform Act and Related Laws.” More recently,the Medicare Access and CHIP Reauthorization Act of 2015 significantly revised the methodology for updating Medicare physician fee schedule. Congresscontinues to consider other healthcare reform legislation. There is no assurance that the Healthcare Reform Act, as currently enacted or as amended in thefuture, will not adversely affect our business and financial results, and we cannot predict how future federal or state legislative, judicial or administrativechanges relating to healthcare reform will affect our business.In addition, other legislative changes have been proposed and adopted since the Healthcare Reform Act was enacted. The Budget Control Act of 2011and subsequent Congressional actions includes provisions to reduce the federal deficit. These provisions have resulted in the imposition of 2% reductions inMedicare payments to providers, which went into effect on April 1, 2013 and will remain in effect through the first half of 2025 unless additionalCongressional action is taken. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs thatmay be implemented and/or any significant taxes or fees that may be imposed on us, as part of any broader deficit reduction effort or legislative replacementto the Budget Control Act, could have an adverse impact on our results of operations.The full impact on our business of the Healthcare Reform Act and the other new laws is uncertain. Nor is it clear whether other legislative changes willbe adopted or how those changes would affect our industry generally or our ability to successfully commercialize our products or the development of newproducts. 36 Table of ContentsThe Healthcare Reform Act could potentially reduce the number of diagnostic medical imaging procedures performed or could reduce the amount ofreimbursements paid for those procedures.The implementation of the Healthcare Reform Act could potentially reduce the aggregate number of diagnostic medical imaging procedures performedin the United States. The Healthcare Reform Act amended the federal self-referral law to require that referring physicians inform patients that the patients mayobtain certain services, including MRI, CT, PET and certain other diagnostic imaging services from a provider other than that physician, another physician inhis or her group practice, or another individual under the direct supervision of the physician or another physician in the group practice. The referringphysician must provide each patient with a written list of other suppliers which furnish those services in the area in which the patient resides. These newrequirements could have the effect of shifting where certain diagnostic medical imaging procedures are performed. In addition, they could potentially reducethe overall number of diagnostic medical imaging procedures performed.Although certain provisions of the Healthcare Reform Act may negatively affect payment rates for certain imaging services, the Healthcare Reform Actis projected to reduce the number of people without health insurance by approximately 13 million by 2016 (based on January 2016 estimates from theCongressional Budget Office), which may result in an increase in the demand for our services, but we cannot be assured of a proportional, or any, increase inthe use of our products.Further, we expect that there will continue to be proposals to reduce or limit Medicare and Medicaid payment for services. Rates paid by some privatethird party payors are based, in part, on established physician, clinic and hospital charges and are generally higher than Medicare payment rates. Reductionsin the amount of reimbursement paid for diagnostic medical imaging procedures and changes in the mix of our patients between non-governmental payorsand government sponsored healthcare programs and among different types of non-government payor sources, could have a material adverse effect on ourbusiness, results of operations, financial condition and cash flows.Our business and industry are subject to complex and costly regulations. If government regulations are interpreted or enforced in a manner adverse tous or our business, we may be subject to enforcement actions, penalties, exclusion and other material limitations on our operations.Both before and after the approval of our products and agents in development, we, our products, development agents, operations, facilities, suppliers,distributors, contract manufacturers, contract research organizations and contract testing laboratories are subject to extensive and, in certain circumstances,expanding regulation by federal, state and local government agencies in the United States as well as non-U.S. and transnational laws and regulations, withregulations differing from country to country. In the United States, the FDA regulates, among other things, the pre-clinical testing, clinical trials,manufacturing, safety, efficacy, potency, labeling, storage, record keeping, quality systems, advertising, promotion, sale, distribution, and import and exportof drug products. We are required to register our business for permits and/or licenses with, and comply with the stringent requirements of the FDA, the NRC,the HHS, Health Canada, the EMA, the MHRA, the CFDA, state and provincial boards of pharmacy, state and provincial health departments and other federal,state and provincial agencies.Under U.S. law, for example, we are required to report certain adverse events and production problems, if any, to the FDA. We also have similar adverseevent and production reporting obligations outside of the United States, including to the EMA and MHRA. Additionally, we must comply with requirementsconcerning advertising and promotion for our products, including the prohibition on the promotion of our products for indications that have not beenapproved by the FDA or a so-called “off-label use.” If the FDA determines that our promotional materials constitute the unlawful promotion of an off-labeluse, it could request that we modify our promotional materials or subject us to regulatory or enforcement actions. Also, quality control and manufacturingprocedures at our own facility and at third party suppliers must conform to cGMP regulations and other applicable law after approval, and the FDAperiodically inspects manufacturing facilities to assess 37 Table of Contentscompliance with cGMPs and other applicable law, and, from time to time, makes those cGMPs more stringent. Accordingly, we and others with whom wework must expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control. For example, wecurrently rely on JHS as our sole manufacturer of DEFINITY, Neurolite and evacuation vials. In 2013, JHS received a warning letter from the FDA inconnection with their manufacturing facility in Spokane, Washington where our products are manufactured. Although the FDA upgraded JHS’s compliancestatus to Voluntary Action Indicated, meaning that any issues are not of “regulatory significance” in June of 2015, if in the future the same or other issuesarise, the FDA could take additional regulatory action which could limit or suspend the ability of JHS to manufacture our products or have any additionalproducts approved at the Spokane facility for manufacture until the issues are resolved and remediated. Such a limitation or suspension could have a materialadverse effect on our business, results of operations, financial condition and cash flows.We are also subject to laws and regulations that govern financial and other arrangements between pharmaceutical manufacturers and healthcareproviders, including federal and state anti-kickback statutes, federal and state false claims laws and regulations and other fraud and abuse laws andregulations. For example, in 2010, we entered into a Medicaid Drug Rebate Agreement with the federal government for some but not all of our products,which requires us to report certain price information to the federal government that could subject us to potential liability under the FCA, civil monetarypenalties or liability under other laws and regulations in connection with the covered products as well as the products not covered by the agreement.Determination of the rebate amount that we pay to state Medicaid programs for our products, as well as determination of payment amounts for some of ourproducts under Medicare and certain other third party payers, including government payers, depends upon information reported by us to the government.CMS recently published final rules on the determination and reporting of average manufacturer price and best price. If we provide customers or governmentofficials with inaccurate information about the products’ pricing or eligibility for coverage, or the products fail to satisfy coverage requirements, we could beterminated from the rebate program, be excluded from participation in government healthcare programs, or be subject to potential liability under the FalseClaims Act or other laws and regulations. See “Business—Regulatory Matters—Healthcare Fraud and Abuse Laws.”Additionally, funds received under all healthcare reimbursement programs are subject to audit with respect to the proper billing by customers. Ourcustomers engage in billing, and retroactive adjustments of revenue received from these programs could occur.Failure to comply with other requirements and restrictions placed upon us or our third party manufacturers or suppliers by laws and regulations canresult in fines, civil and criminal penalties, exclusion from federal healthcare programs and debarment. Possible consequences of those actions could include: • substantial modifications to our business practices and operations; • significantly reduced demand for our products (if products become ineligible for reimbursement under federal and state healthcare programs); • a total or partial shutdown of production in one or more of the facilities where our products are produced while the alleged violation is beingremediated; • delays in or the inability to obtain future pre-market clearances or approvals; and • withdrawals or suspensions of our current products from the market.Regulations are subject to change as a result of legislative, administrative or judicial action, which may also increase our costs or reduce sales.Violation of any of these regulatory schemes, individually or collectively, could disrupt our business and have a material adverse effect on our business,results of operations, financial condition and cash flows. 38 Table of ContentsOur marketing and sales practices may contain risks that could result in significant liability, require us to change our business practices and restrictour operations in the future.We are subject to numerous domestic (federal, state and local) and foreign laws addressing fraud and abuse in the healthcare industry, including theFCA and Federal Anti-Kickback Statute, self-referral laws, the FCPA, the Bribery Act, FDA promotional restrictions, the federal disclosure (sunshine) law andstate marketing and disclosure (sunshine) laws. Violations of these laws are punishable by criminal or civil sanctions, including substantial fines,imprisonment and exclusion from participation in healthcare programs such as Medicare and Medicaid as well as health programs outside the United States,and even alleged violations can result in the imposition of corporate integrity agreements that could severely restrict or limit our business practices. Theselaws and regulations are complex and subject to changing interpretation and application, which could restrict our sales or marketing practices. Even minorand inadvertent irregularities could potentially give rise to a charge that the law has been violated. Although we believe we maintain an appropriatecompliance program, we cannot be certain that the program will adequately detect or prevent violations and/or the relevant regulatory authorities maydisagree with our interpretation. Additionally, if there is a change in law, regulation or administrative or judicial interpretations, we may have to change oneor more of our business practices to be in compliance with these laws. Required changes could be costly and time consuming.The Healthcare Reform Act contains various provisions that further regulate sales and marketing practices. The Healthcare Reform Act imposes newrequirements on certain device and drug manufacturers to report annually certain financial interactions with physicians and teaching hospitals as well asownership and investment interests held by physicians or their immediate family members. The first annual report (submitted in two phases for the initialyear) was submitted in 2014 (covering August 1, 2013 through December 31, 2013), and a second report was submitted in 2015. A manufacturer may besubject to civil monetary penalties of up to $150,000 aggregate per year for failures to report required information and up to $1 million aggregate per year for“knowing” failures to report.The Healthcare Reform Act also separately requires manufacturers to submit information to the FDA on the identity and quantity of drug samplesrequested and distributed by a manufacturer during each year. State laws may also require disclosure of pharmaceutical pricing information and marketingexpenditures, compliance with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by thefederal government, and/or the tracking and reporting of gifts, compensation, and other remuneration to physicians and other healthcare providers. Webelieve we have developed appropriate protocols to implement these reporting requirements. Any irregularities or mistakes in our federal or state reporting,however, could result in a finding that we have been non-compliant with these requirements, which could subject us to the penalty provisions of applicablefederal and state laws and regulations.The Healthcare Reform Act also provides greater financial resources to be allocated to enforcement of the fraud and abuse laws and clarifies the intentrequirements of the Federal Anti-Kickback Statute and the general criminal healthcare fraud statute, which may increase overall compliance costs for industryparticipants, including us. A person or entity does not need to have actual knowledge of the statutes or a specific intent to violate them. In addition, theHealthcare Reform Act revised the FCA to provide that a claim arising from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulentclaim for purposes of the FCA. If our operations are found to be in violation of these laws or any other government regulations that apply to us, we may besubject to penalties, including, without limitation, civil and criminal penalties, damages, fines, imprisonment, the curtailment or restructuring of ouroperations, or exclusion from state and federal healthcare programs including Medicare and Medicaid, any of which could have a material adverse effect onour business, results of operations, financial condition and cash flows. 39 Table of ContentsUltrasound contrast agents may cause side effects which could limit our ability to sell DEFINITY.DEFINITY is an ultrasound contrast agent based on perflutren lipid microspheres. In 2007, the FDA received reports of deaths and seriouscardiopulmonary reactions following the administration of ultrasound micro-bubble contrast agents used in echocardiography. Four of the 11 reported deathswere caused by cardiac arrest occurring either during or within 30 minutes following the administration of the contrast agent; most of the serious but non-fatal reactions also occurred in this time frame. As a result, in October 2007, the FDA requested that we and GE Healthcare, which distributes Optison, acompetitor to DEFINITY, add a boxed warning to these products emphasizing the risk for serious cardiopulmonary reactions and that the use of theseproducts was contraindicated in certain patients. In a strong reaction by the cardiology community to the FDA’s new position, a letter was sent to the FDA,signed by 161 doctors, stating that the benefit of these ultrasound contrast agents outweighed the risks and urging that the boxed warning be removed. InMay 2008, the FDA substantially modified the boxed warning. On May 2, 2011, the FDA held an advisory committee meeting to consider the status ofultrasound micro-bubble contrast agents and the boxed warning. In October 2011, we received FDA approval of further modifications to the DEFINITY label,including: further relaxing the boxed warning; eliminating the sentence in the Indication and Use section “The safety and efficacy of DEFINITY withexercise stress or pharmacologic stress testing have not been established” (previously added in October 2007 in connection with the imposition of the boxwarning); and including summary data from the post-approval CaRES (Contrast echocardiography Registry for Safety Surveillance) safety registry and thepost-approval pulmonary hypertension study. Bracco’s recently approved ultrasound contrast agent, Lumason, has substantially similar safety labeling asDEFINITY and Optison. If additional safety issues arise, this may result in unfavorable changes in labeling or result in restrictions on the approval of ourproduct, including removal of the product from the market. Lingering safety concerns about DEFINITY among some healthcare providers or futureunanticipated side effects or safety concerns associated with DEFINITY could limit expanded use of DEFINITY and have a material adverse effect on the unitsales of this product and our financial condition and results of operations.Our business depends on our ability to successfully introduce new products and adapt to a changing technology and diagnostic landscape.The healthcare industry is characterized by continuous technological development resulting in changing customer preferences and requirements. Thesuccess of new product development depends on many factors, including our ability to fund development of new agents, anticipate and satisfy customerneeds, obtain regulatory approval on a timely basis based on performance of our agents in development versus their clinical study comparators, develop andmanufacture products in a cost-effective and timely manner, maintain advantageous positions with respect to intellectual property and differentiate ourproducts from our competitors. To compete successfully in the marketplace, we must make substantial investments in new product development whetherinternally or externally through licensing or acquisitions. Our failure to introduce new and innovative products in a timely manner would have an adverseeffect on our business, results of operations, financial condition and cash flows.Even if we are able to develop, manufacture and obtain regulatory approvals for our new products, the success of these products would depend uponmarket acceptance and adequate reimbursement. Levels of market acceptance for our new products could be affected by a number of factors, including: • the availability of alternative products from our competitors; • the price of our products relative to those of our competitors; • the timing of our market entry; • our ability to market and distribute our products effectively; • market acceptance of our products; and • our ability to obtain adequate reimbursement. 40 Table of ContentsThe field of diagnostic medical imaging is dynamic, with new products, including equipment and agents, continually being developed and existingproducts continually being refined. Our own diagnostic imaging agents compete not only with other similarly administered imaging agents but also withimaging agents employed in different and often competing diagnostic modalities. New imaging agents in a given diagnostic modality may be developed thatprovide benefits superior to the then-dominant agent in that modality, resulting in commercial displacement. Similarly, changing perceptions aboutcomparative efficacy and safety including, among other things, comparative radiation exposure, as well as changing availability of supply may favor oneagent over another or one modality over another. In addition, new or revised appropriate use criteria developed by professional societies, to assist physiciansand other health care providers in making appropriate imaging decisions for specific clinical conditions, can and have reduced the frequency of and demandfor certain imaging modalities and imaging agents. To the extent there is technological obsolescence in any of our products that we manufacture, resulting inlower unit sales or decreased unit sales prices, we will have increased unit overhead allocable to the remaining market share, which could have a materialadverse effect on our business, results of operations, financial condition and cash flows.The process of developing new drugs and obtaining regulatory approval is complex, time-consuming and costly, and the outcome is not certain.We currently have three agents in development, two of which (flurpiridaz F 18 and 18F LMI 1195) are currently in clinical development, while a third(LMI 1174) is in pre-clinical development. To obtain regulatory approval for these agents, we must conduct extensive human tests, which are referred to asclinical trials, as well as meet other rigorous regulatory requirements, as further described in “Business—Regulatory Matters.” Satisfaction of all regulatoryrequirements typically takes many years and requires the expenditure of substantial resources. A number of other factors may cause significant delays in thecompletion of our clinical trials, including unexpected delays in the initiation of clinical sites, slower than projected enrollment, competition with ongoingclinical trials and scheduling conflicts with participating clinicians, regulatory requirements, limits on manufacturing capacity and failure of an agent to meetrequired standards for administration to humans. In addition, it may take longer than we project to achieve study endpoints and complete data analysis for atrial or we may decide to slow down the enrollment in a trial in order to conserve financial resources.Our agents in development are also subject to the risks of failure inherent in drug development and testing. The results of preliminary studies do notnecessarily predict clinical success, and larger and later stage clinical trials may not produce the same results as earlier stage trials. Sometimes, agents thathave shown promising results in early clinical trials have subsequently suffered significant setbacks in later clinical trials. Agents in later stage clinical trialsmay fail to show desired safety and efficacy traits, despite having progressed through initial clinical testing. Further, the data collected from clinical trials ofour agents in development may not be sufficient to support regulatory approval, or regulators could interpret the data differently and less favorably than wedo. Further, the design of a clinical trial can determine whether its results will support approval of a product, and flaws in the design of a clinical trial may notbecome apparent until the clinical trial is well advanced. Clinical trials of potential products often reveal that it is not practical or feasible to continuedevelopment efforts. Regulatory authorities may require us or our partners to conduct additional clinical testing, in which case we would have to expendadditional time and resources. The approval process may also be delayed by changes in government regulation, future legislation or administrative action orchanges in regulatory policy that occur prior to or during regulatory review. The failure to provide clinical and preclinical data that are adequate todemonstrate to the satisfaction of the regulatory authorities that our agents in development are safe and effective for their proposed use will delay or precludeapproval and will prevent us from marketing those products.In our flurpiridaz F 18 Phase 3 program, in the fourth quarter of 2013, we announced preliminary results from the 301 trial, which is subject to an SPAwith the FDA. Although flurpiridaz F 18 appeared to be well-tolerated from a safety perspective and outperformed SPECT in a highly statistically significantmanner in the co-primary endpoint of sensitivity and in the secondary endpoints of image quality and diagnostic certainty, the agent did not meet its otherco-primary endpoint of non-inferiority for identifying subjects without disease. SPA 41 Table of Contentsagreements are not binding on the FDA and we can give no assurances that the FDA will abide by the terms of our SPA agreement. We also cannot assure anyparticular outcome from regulatory review of the study or the agent, that any of the data generated in the 301 trial will be sufficient to support a NDA,approval, that a strategic partner will have to conduct only one additional clinical trial prior to filing an NDA, or that flurpiridaz F 18 will ever be approvedas a PET MPI imaging agent by the FDA. See “Business—Regulatory Matters—Food and Drug Laws.”We are not permitted to market our agents in development in the United States or other countries until we have received requisite regulatory approvals.For example, securing FDA approval for a new drug requires the submission of an NDA to the FDA for our agents in development. The NDA must includeextensive nonclinical and clinical data and supporting information to establish the agent’s safety and effectiveness for each indication. The NDA must alsoinclude significant information regarding the chemistry, manufacturing and controls for the product. The FDA review process can take many years tocomplete, and approval is never guaranteed. If a product is approved, the FDA may limit the indications for which the product may be marketed, requireextensive warnings on the product labeling, impose restricted distribution programs, require expedited reporting of certain adverse events, or require costlyongoing requirements for post-marketing clinical studies and surveillance or other risk management measures to monitor the safety or efficacy of the agent.Markets outside of the United States also have requirements for approval of agents with which we must comply prior to marketing. Obtaining regulatoryapproval for marketing of an agent in one country does not ensure we will be able to obtain regulatory approval in other countries, but a failure or delay inobtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries. Also, any regulatory approval of any ofour products or agents in development, once obtained, may be withdrawn. Approvals might not be granted on a timely basis, if at all.Any failure or significant delay in completing clinical trials for our product candidates or in receiving regulatory approval for the sale of our productcandidates may severely harm our business and delay or prevent us from being able to generate revenue from product sales.Even if our agents in development proceed successfully through clinical trials and receive regulatory approval, there is no guarantee that an approvedproduct can be manufactured in commercial quantities at a reasonable cost or that such a product will be successfully marketed or distributed. The burdenassociated with the marketing and distributing of products like ours is substantial. For example, rather than being manufactured at our own facilities,flurpiridaz F 18 would require the creation of a complex, field-based network involving PET cyclotrons located at radiopharmacies where the agent wouldneed to be manufactured and distributed rapidly to end-users, given the agent’s 110-minute half-life. In addition, in the case of flurpiridaz F 18, obtainingadequate reimbursement is critical, including not only coverage from Medicare, Medicaid, other government payors as well as private payors but alsoappropriate payment levels which adequately cover the substantially higher manufacturing and distribution costs associated with a PET MPI agent incomparison to, for example, sestamibi.We will not be able to further develop or commercialize our agents in development without successful strategic partners.In March 2013, we began to implement a strategic shift in how we will fund our important R&D programs. We have reduced our internal R&Dresources, while at the same time we are seeking to engage strategic partners to further develop and commercialize our important agents in development,including flurpiridaz F 18, 18F LMI 1195 and LMI 1174. However, different strategic partners may have different time horizons, risk profiles, returnexpectations and amounts of capital to deploy, and we may not be able to negotiate relationships with potential strategic partners on acceptable terms, or atall. If we are unable to establish or maintain these strategic partnerships, we will have to limit the size or scope of, or delay, our development programs. 42 Table of ContentsIn addition, our dependence on strategic partnerships is subject to a number of risks, including: • the inability to control the amount or timing of resources that our partners may devote to developing the agents; • the possibility that we may be required to relinquish important rights, including economic, intellectual property, marketing and distributionrights; • the receipt of lower revenues than if we were to commercialize those agents ourselves; • our failure to receive future milestone payments or royalties if a partner fails to commercialize one of our agents successfully; • the possibility that a partner could separately move forward with competing agents developed either independently or in collaboration withothers, including our competitors; • the possibility that our strategic partners may experience financial or operational difficulties; • business combinations or significant changes in a partner’s business strategy that may adversely affect that partner’s willingness or ability tocomplete its obligations under any arrangement with us; and • the possibility that our partners may operate in countries where their operations could be negatively impacted by changes in the local regulatoryenvironment or by political unrest.Any of these factors either alone or taken together could have a material adverse effect on our business, results of operations, financial condition andcash flows.A heightened public or regulatory focus on the radiation risks of diagnostic imaging could have an adverse effect on our business.We believe that there has been heightened public and regulatory focus on radiation exposure, including the concern that repeated doses of radiationused in diagnostic imaging procedures pose the potential risk of long-term cell damage, cancer and other diseases. For example, starting in January 2012,CMS required the accreditation of facilities providing the technical component of advanced imaging services, including CT, MRI, PET and nuclearmedicine, in non-hospital freestanding settings. In August 2011, The Joint Commission (an independent, not-for-profit organization that accredits andcertifies more than 20,500 healthcare organizations and programs in the United States) issued an alert on the radiation risks of diagnostic imaging andrecommended specific actions for providing “the right test and the right dose through effective processes, safe technology and a culture of safety.” Revisedaccreditation standards issued by The Joint Commission for diagnostic imaging took effect in July 2015.Heightened regulatory focus on risks caused by the radiation exposure received by diagnostic imaging patients could lead to increased regulation ofradiopharmaceutical manufacturers or healthcare providers who perform procedures that use our imaging agents, which could make the procedures morecostly, reduce the number of providers who perform procedures and/or decrease the demand for our products. In addition, heightened public focus on or fearof radiation exposure could lead to decreased demand for our products by patients or by healthcare providers who order the procedures in which our agentsare used. Although we believe that our diagnostic imaging agents when properly used do not expose patients and healthcare providers to unsafe levels ofradiation, any of the foregoing risks could have an adverse effect on our business, results of operations, financial condition and cash flows.In the ordinary course of business, we may be subject to product liability claims and lawsuits, including potential class actions, alleging that ourproducts have resulted or could result in an unsafe condition or injury.Any product liability claim brought against us, with or without merit, could be time consuming and costly to defend and could result in an increase ofour insurance premiums. Although we have not had any such claims to date, claims that could be brought against us might not be covered by our insurancepolicies. Furthermore, 43 Table of Contentsalthough we currently have product liability insurance coverage with policy limits that we believe are customary for pharmaceutical companies in thediagnostic medical imaging industry and adequate to provide us with insurance coverage for foreseeable risks, even where the claim is covered by ourinsurance, our insurance coverage might be inadequate and we would have to pay the amount of any settlement or judgment that is in excess of our policylimits. We may not be able to obtain insurance on terms acceptable to us or at all, since insurance varies in cost and can be difficult to obtain. Our failure tomaintain adequate insurance coverage or successfully defend against product liability claims could have a material adverse effect on our business, results ofoperations, financial condition and cash flows.We use hazardous materials in our business and must comply with environmental laws and regulations, which can be expensive.Our operations use hazardous materials and produce hazardous wastes, including radioactive, chemical and, in certain circumstances, biologicalmaterials and wastes. We are subject to a variety of federal, state and local laws and regulations as well as non-U.S. laws and regulations relating to thetransport, use, handling, storage, exposure to and disposal of these materials and wastes. Environmental laws and regulations are complex, change frequentlyand have become more stringent over time. We are required to obtain, maintain and renew various environmental permits and nuclear licenses. Although webelieve that our safety procedures for transporting, using, handling, storing and disposing of, and limiting exposure to, these materials and wastes comply inall material respects with the standards prescribed by applicable laws and regulations, the risk of accidental contamination or injury cannot be eliminated. Weplace a high priority on these safety procedures and seek to limit any inherent risks. We generally contract with third parties for the disposal of wastesgenerated by our operations. Prior to disposal, we store any low level radioactive waste at our facilities to decay until the materials are no longer consideredradioactive. Although we believe we have complied in all material respects with all applicable environmental, health and safety laws and regulations, wecannot assure you that we have been or will be in compliance with all such laws at all times. If we violate these laws, we could be fined, criminally charged orotherwise sanctioned by regulators. We may be required to incur further costs to comply with current or future environmental and safety laws and regulations.In addition, in the event of accidental contamination or injury from these materials, we could be held liable for any damages that result and any such liabilitycould exceed our resources.While we have budgeted for current and future capital and operating expenditures to maintain compliance with these laws and regulations, we cannotassure you that our costs of complying with current or future environmental, health and safety laws and regulations will not exceed our estimates or adverselyaffect our results of operations and financial condition. Further, we cannot assure you that we will not be subject to additional environmental claims forpersonal injury, investigation or cleanup in the future based on our past, present or future business activities.If we are unable to protect our intellectual property, our competitors could develop and market products with features similar to our products, anddemand for our products may decline.Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of our technologies and agentsin development as well as successfully defending these patents and trade secrets against third party challenges, both in the United States and in foreigncountries. We will only be able to protect our intellectual property from unauthorized use by third parties to the extent that we maintain the secrecy of ourtrade secrets and can enforce our valid patents and trademarks.The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions forwhich important legal principles remain unresolved. In addition, changes in either the patent laws or in interpretations of patent laws in the United States orother countries may diminish the value of our intellectual property and we may not receive the same degree of protection in every jurisdiction. Accordingly,we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third party patents. 44 Table of ContentsThe degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequatelyprotect our rights or permit us to gain or keep our competitive advantage. For example: • we might not have been the first to make the inventions covered by each of our pending patent applications and issued patents, and we couldlose our patent rights as a result; • we might not have been the first to file patent applications for these inventions or our patent applications may not have been timely filed, and wecould lose our patent rights as a result; • others may independently develop similar or alternative technologies or duplicate any of our technologies; • it is possible that none of our pending patent applications will result in any further issued patents; • our issued patents may not provide a basis for commercially viable drugs, may not provide us with any protection from unauthorized use of ourintellectual property by third parties, and may not provide us with any competitive advantages; • our patent applications or patents may be subject to interferences, oppositions, post-grant review, reexaminations or similar administrativeproceedings; • while we generally apply for patents in those countries where we intend to make, have made, use or sell patented products, we may not be able toaccurately predict all of the countries where patent protection will ultimately be desirable and may be precluded from doing so at a later date; • we may choose not to seek patent protection in certain countries where the actual cost outweighs the perceived benefit at a certain time; • patents issued in foreign jurisdictions may have different scopes of coverage as our United States patents and so our products may not receive thesame degree of protection in foreign countries as they would in the United States; • we may not develop additional proprietary technologies that are patentable; or • the patents of others may have an adverse effect on our business.Moreover, the issuance of a patent is not conclusive as to its validity or enforceability. A third party may challenge the validity or enforceability of apatent even after its issuance by the U.S. Patent and Trademark Office or the applicable foreign patent office. It is also uncertain how much protection, if any,will be afforded by our patents if we attempt to enforce them and they are challenged in court or in other proceedings, which may be brought in U.S. or non-U.S. jurisdictions to challenge the validity of a patent.The defense and prosecution of intellectual property suits, interferences, oppositions and related legal and administrative proceedings are costly, timeconsuming to pursue and result in diversion of resources. The outcome of these proceedings is uncertain and could significantly harm our business. If we arenot able to defend the patents of our technologies and products, then we will not be able to exclude competitors from marketing products that directlycompete with our products, which could have a material adverse effect on our business, results of operations, financial condition and cash flows.We will also rely on trade secrets and other know-how and proprietary information to protect our technology, especially where we do not believepatent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We use reasonable efforts to protect our trade secrets, but ouremployees, consultants, contractors, outside scientific partners and other advisors may unintentionally or willfully disclose our confidential information tocompetitors or other third parties. Enforcing a claim that a third party improperly obtained and is using our trade secrets is expensive and time consuming,and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our 45 Table of Contentscompetitors may independently develop equivalent knowledge, methods and know-how. We often rely on confidentiality agreements with our collaborators,employees, consultants and other third parties and invention assignment agreements with our employees to protect our trade secrets and other know-how andproprietary information concerning our business. These confidentiality agreements may not prevent unauthorized disclosure of trade secrets and other know-how and proprietary information, and there can be no guarantee that an employee or an outside party will not make an unauthorized disclosure of our tradesecrets, other technical know-how or proprietary information, or that we can detect such an unauthorized disclosure. We may not have adequate remedies forany unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitor will make use of that information, and that ourcompetitive position will be compromised, in spite of any legal action we might take against persons making those unauthorized disclosures, which couldhave a material adverse effect on our business, results of operations, financial condition and cash flows.We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors, and have registered orapplied to register many of these trademarks, including DEFINITY, Cardiolite, TechneLite, Neurolite, Ablavar, Quadramet and Lantheus Medical Imaging.We cannot assure you that any pending trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwisechallenge our use of the trademarks. If our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss ofbrand recognition, and could require us to devote resources to advertising and marketing new brands. Further, we cannot assure you that competitors will notinfringe our trademarks, or that we will have adequate resources to enforce our trademarks.We may be subject to claims that we have infringed, misappropriated or otherwise violated the patent or other intellectual property rights of a thirdparty. The outcome of any of these claims is uncertain and any unfavorable result could adversely affect our business, financial condition and results ofoperations.We may be subject to claims by third parties that we have infringed, misappropriated or otherwise violated their intellectual property rights. While webelieve that the products that we currently manufacture using our proprietary technology do not infringe upon or otherwise violate proprietary rights of otherparties or that meritorious defenses would exist with respect to any assertions to the contrary, we cannot assure you that we would not be found to infringe onor otherwise violate the proprietary rights of others.We may be subject to litigation over infringement claims regarding the products we manufacture or distribute. This type of litigation can be costly andtime consuming and could divert management’s attention and resources, generate significant expenses, damage payments (potentially including trebledamages) or restrictions or prohibitions on our use of our technology, which could adversely affect our results of operations. In addition, if we are found to beinfringing on proprietary rights of others, we may be required to develop non-infringing technology, obtain a license (which may not be available onreasonable terms, or at all), make substantial one-time or ongoing royalty payments, or cease making, using and/or selling the infringing products, any ofwhich could have a material adverse effect on our business, results of operations, financial condition and cash flows.We may be adversely affected by prevailing economic conditions and financial, business and other factors beyond our control.Our ability to attract and retain customers, invest in and grow our business and meet our financial obligations depends on our operating and financialperformance, which, in turn, is subject to numerous factors, including the prevailing economic conditions and financial, business and other factors beyondour control, such as the rate of unemployment, the number of uninsured persons in the United States and inflationary pressures. We cannot anticipate all theways in which the current economic climate and financial market conditions could adversely impact our business.We are exposed to risks associated with reduced profitability and the potential financial instability of our customers, many of which may be adverselyaffected by volatile conditions in the financial markets. For example, unemployment and underemployment, and the resultant loss of insurance, may decreasethe demand for 46 Table of Contentshealthcare services and pharmaceuticals. If fewer patients are seeking medical care because they do not have insurance coverage, our customers mayexperience reductions in revenues, profitability and/or cash flow that could lead them to modify, delay or cancel orders for our products. If customers are notsuccessful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, accountsreceivable that are owed to us. This, in turn, could adversely affect our financial condition and liquidity. To the extent prevailing economic conditions resultin fewer procedures being performed, our business, results of operations, financial condition and cash flows could be adversely affected.Our business is subject to international economic, political and other risks that could negatively affect our results of operations or financial position.For the years ended December 31, 2015, 2014 and 2013, 20%, 22% and 25%, respectively, of our revenues were derived from outside the fifty UnitedStates. We anticipate that revenue from non-U.S. operations will grow in the future. Accordingly, our business is subject to risks associated with doingbusiness internationally, including: • less stable political and economic environments and changes in a specific country’s or region’s political or economic conditions; • entering into or renewing commercial agreements with international governments or provincial authorities or entities directly or indirectlycontrolled by such governments or authorities, such as our Chinese partner Double-Crane; • international customers which are agencies or institutions of foreign governments; • local business practices which may be in conflict with the FCPA and Bribery Act; • currency fluctuations; • potential negative consequences from changes in tax laws affecting our ability to repatriate profits; • unfavorable labor regulations; • greater difficulties in relying on non-U.S. courts to enforce either local or U.S. laws, particularly with respect to intellectual property; • greater potential for intellectual property piracy; • greater difficulties in managing and staffing non-U.S. operations; • the need to ensure compliance with the numerous in-country and international regulatory and legal requirements applicable to our business ineach of these jurisdictions and to maintain an effective compliance program to ensure compliance with these requirements; • changes in public attitudes about the perceived safety of nuclear facilities; • changes in trade policies, regulatory requirements and other barriers; • civil unrest or other catastrophic events; and • longer payment cycles of non-U.S. customers and difficulty collecting receivables in non-U.S. jurisdictions.These factors are beyond our control. The realization of any of these or other risks associated with operating outside the fifty United States could havea material adverse effect on our business, results of operations, financial condition and cash flows. As our international exposure increases and as we executeour strategy of international expansion, these risks may intensify. 47 Table of ContentsWe face currency and other risks associated with international sales.We generate significant revenue from export sales, as well as from operations conducted outside the fifty United States. During the years endedDecember 31, 2015, 2014 and 2013, the net impact of foreign currency changes on transactions was a loss of $1.8 million, $279,000 and $349,000,respectively. Operations outside the United States expose us to risks including fluctuations in currency values, trade restrictions, tariff and trade regulations,U.S. export controls, non-U.S. tax laws, shipping delays and economic and political instability. For example, violations of U.S. export controls, includingthose administered by the U.S. Treasury Department’s Office of Foreign Assets Control, could result in fines, other civil or criminal penalties and thesuspension or loss of export privileges which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.The functional currency of each of our non-U.S. operations is generally the local currency, although one non-U.S. operation’s functional currency is theU.S. Dollar. Exchange rates between some of these currencies and U.S. Dollar have fluctuated significantly in recent years and may do so in the future.Historically, we have not used derivative financial instruments or other financial instruments to hedge those economic exposures. In 2015, fluctuations inexchange rates had a $6.8 million negative effect on our revenues.U.S. credit markets may impact our ability to obtain financing or increase the cost of future financing, including, in the event we obtain financing witha variable interest rate, interest rate fluctuations based on macroeconomic conditions that are beyond our control.During periods of volatility and disruption in the U.S., European, or global credit markets, obtaining additional or replacement financing may be moredifficult and the cost of issuing new debt or replacing our Revolving Facility and/or term facility (collectively, our senior secured credit facilities) could behigher than under our current senior secured credit facilities. Higher cost of new debt may limit our ability to have cash on hand for working capital, capitalexpenditures and acquisitions on terms that are acceptable to us. Additionally, our senior secured credit facilities have a variable interest rate. By its nature, avariable interest rate will move up or down based on changes in the economy and other factors, all of which are beyond our control. If interest rates increase,our interest expense could increase, affecting earnings and reducing cash flows available for working capital, capital expenditures and acquisitions.Many of our customer relationships outside of the United States are, either directly or indirectly, with governmental entities, and we could be adverselyaffected by violations of the FCPA and similar worldwide anti-bribery laws outside the United States.The FCPA, the Bribery Act and similar worldwide anti-bribery laws in non-U.S. jurisdictions generally prohibit companies and their intermediariesfrom making improper payments to non-U.S. officials for the purpose of obtaining or retaining business.The FCPA prohibits us from providing anything of value to foreign officials for the purposes of obtaining or retaining business or securing anyimproper business advantage. It also requires us to keep books and records that accurately and fairly reflect our transactions. Because of the predominance ofgovernment-sponsored healthcare systems around the world, many of our customer relationships outside of the United States are, either directly or indirectly,with governmental entities and are therefore subject to the FCPA and similar anti-bribery laws in non-U.S. jurisdictions. In addition, the Bribery Act has beenenacted, and its provisions extend beyond bribery of foreign public officials and are more onerous than the FCPA in a number of other respects, includingjurisdiction, non-exemption of facilitation payments and penalties.Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that have experienced governmental corruptionto some degree, and in certain circumstances strict compliance with anti-bribery laws may conflict with local customs and practices. Despite our training andcompliance programs, 48 Table of Contentsour internal control policies and procedures may not always protect us from reckless or criminal acts committed by our employees or agents. Violations ofthese laws, or allegations of those violations, could disrupt our business and result in a material adverse effect on our results of operations, financial conditionand cash flows.Our business depends on the continued effectiveness and availability of our information technology infrastructure, and failures of this infrastructurecould harm our operations.To remain competitive in our industry, we must employ information technologies to support manufacturing processes, quality processes, distribution,R&D and regulatory applications and that capture, manage and analyze the large streams of data generated in our clinical trials in compliance withapplicable regulatory requirements. We rely extensively on technology, some of which is managed by third-party service providers, to allow the concurrentconduct of work sharing around the world. As with all information technology, our equipment and infrastructure age and become subject to increasingmaintenance and repair and our systems generally are vulnerable to potential damage or interruptions from fires, natural disasters, power outages, blackouts,machinery breakdown, telecommunications failures and other unexpected events, as well as to break-ins, sabotage, increasingly sophisticated intentional actsof vandalism or cyber threats. As these threats continue to evolve, we may be required to expend additional resources to enhance our information securitymeasures or to investigate and remediate any information security vulnerabilities. Given the extensive reliance of our business on technology, anysubstantial disruption or resulting loss of data that is not avoided or corrected by our backup measures could harm our business, operations and financialcondition.We may not be able to hire or retain the number of qualified personnel, particularly scientific, medical and sales personnel, required for our business,which would harm the development and sales of our products and limit our ability to grow.Competition in our industry for highly skilled scientific, healthcare and sales personnel is intense. Although we have not had any material difficulty inthe past in hiring or retaining qualified personnel other than from this intense competition, if we are unable to retain our existing personnel, or attract andtrain additional qualified personnel, either because of competition in our industry for these personnel or because of insufficient financial resources, then ourgrowth may be limited and it could have a material adverse effect on our business.If we lose the services of our key personnel, our business could be adversely affected.Our success is substantially dependent upon the performance, contributions and expertise of our chief executive officer, executive leadership andsenior management team. Mary Anne Heino, our Chief Executive Officer and President, and other members of our executive leadership and seniormanagement team play a significant role in generating new business and retaining existing customers. We have an employment agreement with Ms. Heinoand a limited number of other individuals on our executive leadership team, although we cannot prevent them from terminating their employment with us.We do not maintain key person life insurance policies on any of our executive officers. While we have experienced both voluntary and involuntary turnoveron our executive leadership team, to date we have been able to attract new, qualified individuals to lead our company and key functional areas. All of theoptions granted to employees under our 2008 Equity Incentive Plan and 2013 Equity Incentive Plan are currently out-of-the-money, although we have alsomade restricted stock grants to employees under our 2013 Equity Incentive Plan and 2015 Equity Incentive Plan. Our inability to retain our existingexecutive leadership and senior management team, maintain an appropriate internal succession program or attract and retain additional qualified personnelcould have a material adverse effect on our business. 49 Table of ContentsOur future growth may depend on our ability to identify and in-license or acquire additional products, and if we do not successfully do so, or otherwisefail to integrate any new products into our operations, we may have limited growth opportunities and it could materially adversely affect ourrelationships with customers and/or result in significant impairment charges.We are continuing to seek to acquire or in-license products, businesses or technologies that we believe are a strategic fit with our business strategy.Future in-licenses or acquisitions, however, may entail numerous operational and financial risks, including: • exposure to unknown liabilities; • disruption of our business, customer base and diversion of our management’s time and attention to develop acquired products or technologies; • a reduction of our current financial resources; • difficulty or inability to secure financing to fund development activities for those acquired or in-licensed technologies; • incurrence of substantial debt or dilutive issuances of securities to pay for acquisitions; and • higher than expected acquisition and integration costs.We may not have sufficient resources to identify and execute the acquisition or in-licensing of third party products, businesses and technologies andintegrate them into our current infrastructure. In particular, we may compete with larger pharmaceutical companies and other competitors in our efforts toestablish new collaborations and in-licensing opportunities. These competitors likely will have access to greater financial resources than we do and may havegreater expertise in identifying and evaluating new opportunities. Furthermore, there may be overlap between our products or customers and the companieswhich we acquire that may create conflicts in relationships or other commitments detrimental to the integrated businesses. Additionally, the time between ourexpenditures to in-license or acquire new products, technologies or businesses and the subsequent generation of revenues from those acquired products,technologies or businesses (or the timing of revenue recognition related to licensing agreements and/or strategic collaborations) could cause fluctuations inour financial performance from period to period. Finally, if we devote resources to potential acquisitions or in-licensing opportunities that are nevercompleted, or if we fail to realize the anticipated benefits of those efforts, we could incur significant impairment charges or other adverse financialconsequences.We have a substantial amount of indebtedness which may limit our financial and operating activities and may adversely affect our ability to incuradditional debt to fund future needs.As of December 31, 2015, we had approximately $363.2 million of total principal indebtedness consisting entirely of the seven-year Term Facility,which matures on June 30, 2022. As of December 31, 2015, there is an $8.8 million unfunded Standby Letter of Credit. Our aggregate Borrowing Base wasapproximately $48.2 million, which was reduced by an $8.8 million unfunded Standby Letter of Credit and $0.1 million in accrued interest, resulting inremaining availability under our Revolving Facility of $39.3 million. Our substantial indebtedness and any future indebtedness we incur could: • require us to dedicate a substantial portion of cash flow from operations to the payment of interest on and principal of our indebtedness, therebyreducing the funds available for other purposes; • make it more difficult for us to satisfy and comply with our obligations with respect to our outstanding indebtedness, namely the payment ofinterest and principal; • make it more difficult to refinance the outstanding indebtedness; • subject us to increased sensitivity to interest rate increases; • make us more vulnerable to economic downturns, adverse industry or company conditions or catastrophic external events; 50 Table of Contents • limit our ability to withstand competitive pressures; • reduce our flexibility in planning for or responding to changing business, industry and economic conditions; and • place us at a competitive disadvantage to competitors that have relatively less debt than we have.In addition, our substantial level of indebtedness could limit our ability to obtain additional financing on acceptable terms, or at all, for workingcapital, capital expenditures and general corporate purposes. Our liquidity needs could vary significantly and may be affected by general economicconditions, industry trends, performance and many other factors not within our control.We may not be able to generate sufficient cash flow to meet our debt service obligations.Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt obligations will depend on our future financialperformance, which will be affected by a range of economic, competitive and business factors, many of which are outside of our control. If we do not generatesufficient cash flow from operations to satisfy our debt obligations, including interest and principal payments, our credit ratings could be downgraded, andwe may have to undertake alternative financing plans, such as refinancing or restructuring our debt, selling assets, entering into additional corporatecollaborations or licensing arrangements for one or more of our products or agents in development, reducing or delaying capital investments or seeking toraise additional capital. We cannot assure you that any refinancing would be possible, that any assets could be sold, licensed or partnered, or, if sold, licensedor partnered, of the timing of the transactions and the amount of proceeds realized from those transactions, that additional financing could be obtained onacceptable terms, if at all, or that additional financing would be permitted under the terms of our various debt instruments then in effect. Furthermore, ourability to refinance would depend upon the condition of the financial and credit markets. Our inability to generate sufficient cash flow to satisfy our debtobligations, or to refinance our obligations on commercially reasonable terms or on a timely basis, would have an adverse effect on our business, results ofoperations and financial condition.Despite our substantial indebtedness, we may incur more debt, which could exacerbate the risks described above.We and our subsidiaries may be able to incur substantial additional indebtedness in the future subject to the limitations contained in the agreementsgoverning our debt, including the senior secured credit facilities. Although these agreements restrict us and our restricted subsidiaries from incurringadditional indebtedness, these restrictions are subject to important exceptions and qualifications. For example, we are generally permitted to incur certainindebtedness, including indebtedness arising in the ordinary course of business, indebtedness among restricted subsidiaries and us and indebtedness relatingto hedging obligations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—External Sources of Liquidity.” If we or our subsidiaries incur additional debt, the risks that we and they now face as a result of our high leverage couldintensify. In addition, the agreements governing our senior secured credit facilities will not prevent us from incurring obligations that do not constituteindebtedness under the agreements.Our debt agreements contain restrictions that will limit our flexibility in operating our business.Our agreements governing our senior secured credit facilities contain various covenants that limit our ability to engage in specified types oftransactions. These covenants limit our and our restricted subsidiaries’ ability to, among other things: • maintain net leverage above certain specified levels; • incur additional debt; • pay dividends or make other distributions; 51 Table of Contents • redeem stock; • issue stock of subsidiaries; • make certain investments; • create liens; • enter into transactions with affiliates; and • merge, consolidate or transfer all or substantially all of our assets.A breach of any of these covenants could result in a default under the agreements governing our senior secured credit facilities. We may also be unableto take advantage of business opportunities that arise because of the limitations imposed on us by the restrictive covenants under our indebtedness.We may be limited in our ability to utilize, or may not be able to utilize, net operating loss carryforwards to reduce our future tax liability.As of December 31, 2015, we had federal income tax loss carryovers of $175.5 million, which will begin to expire in 2031 and will completely expirein 2034. We have had significant financial losses in previous years and as a result we currently maintain a full valuation allowance for our deferred tax assetsincluding our federal and state tax loss carryforwards.Our stock price could fluctuate significantly, which could cause the value of your investment to decline, and you may not be able to resell your shares ator above the initial public offering price.Securities markets worldwide have experienced, and may continue to experience, significant price and volume fluctuations. This market volatility, aswell as general economic, market or political conditions, could reduce the market price of our common stock regardless of our operating performance. Thetrading price of our common stock is likely to be volatile and subject to wide price fluctuations in response to various factors, including: • market conditions in the broader stock market; • actual or anticipated fluctuations in our quarterly financial and operating results; • introduction of new products or services by us or our competitors; • anticipated and reported clinical trial results; • issuance of new or changed securities analysts’ reports or recommendations; • investor perceptions of us and the specialty pharmaceutical industry; • sales, or anticipated sales, of large blocks of our stock; • additions or departures of key personnel; • regulatory or political developments; • litigation and governmental investigations; and • changing economic conditions.These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investorsfrom readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In addition, in the past, when themarket price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the company that issued thestock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the timeand attention of our management from our business, which could significantly harm our profitability and reputation. 52 Table of ContentsIf securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding ourstock or if our results of operations do not meet their expectations, our stock price and trading volume could decline.The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or ourbusiness. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financialmarkets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrade our stock,or if our results of operations do not meet their expectations, our stock price could decline.We do not anticipate paying any cash dividends for the foreseeable future.We currently intend to retain our future earnings, if any, for the foreseeable future, to repay indebtedness and to fund the development and growth ofour business. We do not intend to pay any dividends to holders of our common stock and the agreements governing our senior secured credit facilities limitour ability to pay dividends. As a result, capital appreciation in the price of our common stock, if any, will be your only source of gain on an investment inour common stock. See “Item 5—Dividend Policy”.Item 1B. Unresolved Staff CommentsNone.Item 2. PropertiesOur executive offices and primary manufacturing facilities are located at our North Billerica, Massachusetts facility, which we own. In addition, as ofDecember 31, 2015, we lease five facilities in Canada, two in Australia and one in Puerto Rico. Our owned facilities consist of approximately 578,000 squarefeet of manufacturing, laboratory, mixed use and office space, and our leased facilities consist of approximately 61,186 square feet of manufacturing,laboratory, mixed use and office space. We believe all of these facilities are well-maintained and suitable for the office, radiopharmacy, manufacturing orwarehouse operations conducted in them.The following table summarizes information regarding our significant leased and owned properties, as of December 31, 2015: Location Squarefootage Owned/Leased United States North Billerica, Massachusetts 578,000 Owned Canada Montreal 8,729 Leased Dorval 13,079 Leased Quebec 6,261 Leased Mississauga 13,747 Leased Vancouver 880 Leased Australia Melbourne 4,634 Leased Adelaide 4,306 Leased Puerto Rico San Juan 9,550 Leased On January 12, 2016, we sold our Canadian radiopharmacies to Isologic and entered into a long-term supply agreement with Isologic under which wewill supply Isologic with certain of our products on commercial terms. As a condition to the consummation of that transaction, we agreed to remain aguarantor of the lease obligations to the Mississauga landlord through the current lease term in 2020, subject to certain limitations. 53 Table of ContentsItem 3. Legal ProceedingsFrom time to time, we are a party to various legal proceedings arising in the ordinary course of business. In addition, we have in the past been, and mayin the future be, subject to investigations by governmental and regulatory authorities which expose us to greater risks associated with litigation, regulatory orother proceedings, as a result of which we could be required to pay significant fines or penalties. The outcome of litigation, regulatory or other proceedingscannot be predicted with certainty, and some lawsuits, claims, actions or proceedings may be disposed of unfavorably to us. In addition, intellectual propertydisputes often have a risk of injunctive relief which, if imposed against us, could materially and adversely affect our financial condition or results ofoperations.On December 16, 2010, we filed suit against one of our insurance carriers seeking to recover business interruption losses associated with the NRUreactor shutdown and the ensuing global Moly supply shortage (Lantheus Medical Imaging, Inc., Plaintiff v. Zurich American Insurance Company,Defendant, United States District Court, Southern District of New York, Case No. 10 Civ 9371). The claim is the result of the shutdown of the NRU reactor inChalk River, Ontario. The NRU reactor was off-line from May 2009 until August 2010. The defendant answered the complaint on January 21, 2011, denyingsubstantially all of the allegations, presenting certain defenses and requesting dismissal of the case with costs and disbursements. Discovery, includinginternational discovery and related motion practice, went on for more than three years. The defendant filed a motion for summary judgment on July 14, 2014.We filed a memorandum of law in opposition to defendant’s motion for summary judgment on August 25, 2014. The defendant filed a reply memorandum oflaw in further support of its motion for summary judgment on September 15, 2014. Expert witness discovery was completed on October 31, 2014. OnMarch 25, 2015, the United States District Court for the Southern District of New York granted defendant’s motion for summary judgment. On September 4,2015, we filed an appeal of the District Court decision with the United States Court of Appeals for the Second Circuit. On December 4, 2015, the defendantfiled an answer brief to our appeal, and on December 18, 2015, we filed a reply brief to the defendant’s answer. We cannot be certain when, if ever, we will beable to recover for business interruption losses related to this matter and in what amount, if any.Except as noted above, as of December 31, 2015, we had no material ongoing litigation, regulatory or other proceeding and had no knowledge of anyinvestigations by governmental or regulatory authorities in which we are a target that could have a material adverse effect on our current business.Item 4. Mine Safety DisclosuresNot applicable 54 Table of ContentsPART IIItem 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity SecuritiesMarket InformationOn June 30, 2015, the Company completed an IPO of its common stock at a price to the public of $6.00 per share. The Company’s common stock isnow traded on the NASDAQ under the symbol “LNTH”. Prior to June 25, 2015, our common stock was privately held and there was no established publictrading market for our common stock. The following table presents, for the periods indicated, the high and low closing prices per share of our common sharesas reported on the NASDAQ. FY 2015 Period High Low Second Quarter (June 25, 2015—June 30, 2015) $6.77 $6.15 Third Quarter (July 1, 2015—September 30, 2015) $8.56 $4.30 Fourth Quarter (October 1, 2015—December 31, 2015) $4.76 $2.93 Holders of RecordOn March 2, 2016, there were approximately 90 shareholders of record of our common stock. This number does not include shareholders for whomshares are held in “nominee” or “street” name.Issuer Purchase of Equity SecuritiesNone.Dividend PolicyWe did not declare or pay any dividends and we do not currently intend to pay dividends in the foreseeable future. We currently expect to retain futureearnings, if any, for the foreseeable future, to repay indebtedness and to finance the growth and development of our business.Recent Sales of Unregistered SecuritiesNone.Securities Authorized for Issuance Under Equity Compensations PlansThe information required with respect to this item is incorporated herein by reference to our Definitive Proxy Statement for our 2016 Annual Meetingof Stockholders to be filed with the Securities and Exchange Commission no later than 120 days after the close of our year ended December 31, 2015.Item 6. Selected Financial DataBasis of Financial InformationThe financial statements have been prepared in U.S. Dollars, in accordance with accounting principles generally accepted in the United States ofAmerica, or U.S. GAAP. The condensed consolidated financial statements include the accounts of Holdings and its wholly-owned subsidiaries. Allintercompany accounts and transactions have been eliminated in consolidation. 55 Table of ContentsNon-GAAP Financial MeasuresAdjusted EBITDA and EBITDA as used in our equity incentive plans, collectively, our Non-GAAP Measures, as presented in this annual report, aresupplemental measures of our performance that are not required by, or presented in accordance with U.S. GAAP. They are not measurements of our financialperformance under U.S. GAAP and should not be considered as alternatives to net income (loss) or any other performance measures derived in accordancewith U.S. GAAP or as alternatives to cash flow from operating activities as measures of our liquidity.Our presentation of our Non-GAAP Measures may not be comparable to similarly titled measures of other companies. We have included informationconcerning our Non-GAAP Measures in this annual report because we believe that this information is used by certain investors as measures of a company’shistorical performance.Our Non-GAAP Measures have limitations as analytical tools, and you should not consider them in isolation, or as substitutes for analysis of ouroperating results or cash flows as reported under U.S. GAAP. Some of these limitations include: • they do not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; • they do not reflect changes in, or cash requirements for, our working capital needs; • they do not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments, on our debt; • although depreciation is a non-cash charge, the assets being depreciated will often have to be replaced in the future, and our Non-GAAPMeasures do not reflect any cash requirements for those replacements; • they are not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows; and • other companies in our industry may calculate these measures differently than we do, limiting their usefulness as comparative measures.Because of these limitations, our Non-GAAP Measures should not be considered as measures of discretionary cash available to us to invest in thegrowth of our business. We compensate for these limitations by relying primarily on our U.S. GAAP results and using our Non-GAAP Measures only forsupplemental purposes.Selected Financial DataThe following tables set forth certain selected consolidated financial data as of December 31, 2015 and 2014 and for the fiscal years endedDecember 31, 2015, 2014, and 2013 are derived from our audited financial statements, included in this Annual Report on Form 10-K.

EBITDA is a measure usedby management to measure operating performance. Adjusted EBITDA is defined as EBITDA, further adjusted to exclude certain items and otheradjustments required or permitted in calculating Adjusted EBITDA under the agreements governing the senior secured credit facilities. AdjustedEBITDA is also used by management to measure operating performance and by investors to measure a company’s ability to service its debt and meet itsother cash needs. Management 57 Table of Contents believes that the inclusion of the adjustments to EBITDA applied in presenting Adjusted EBITDA are appropriate to provide additional information toinvestors about the Company’s performance across reporting periods on a consistent basis by excluding items that it does not believe are indicative ofits core operating performance.

Management’s Discussion and Analysis of Financial Condition and Results of OperationsThe following discussion and analysis of our financial condition and results of operations should be read together with “Item 6—Selected FinancialData” and the consolidated financial statements and the related notes included in Item 8 of this annual report. This discussion contains forward-lookingstatements related to future events and our future financial performance that are based on current expectations and subject to risks and uncertainties. Ouractual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under“Item 1A—Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”OverviewWe are a global leader in the development, manufacture and commercialization of innovative diagnostic medical imaging agents and products thatassist clinicians in the diagnosis and treatment of cardiovascular and other diseases. Our agents are routinely used to diagnose coronary artery disease,congestive heart failure, stroke, peripheral vascular disease and other diseases. Clinicians use our imaging agents and products across a range of imagingmodalities, including nuclear imaging, echocardiography and MRI. We believe that the resulting improved diagnostic information enables healthcareproviders to better detect and characterize, or rule out, disease, potentially achieving improved patient outcomes, reducing patient risk and limiting overallcosts for payers and the entire healthcare system.Our commercial products are used by nuclear physicians, cardiologists, radiologists, internal medicine physicians, technologists and sonographersworking in a variety of clinical settings. We sell our products to radiopharmacies, hospitals, clinics, group practices, integrated delivery networks, grouppurchasing organizations and, in certain circumstances, wholesalers.We sell our products globally and have operations in the United States, Puerto Rico, Canada and Australia and distribution relationships in Europe,Asia Pacific and Latin America.Our ProductsOur principal products include the following:DEFINITY is an ultrasound contrast agent used in ultrasound exams of the heart, also known as echocardiography exams. DEFINITY containsperflutren-containing lipid microspheres and is indicated in the United States for use in patients with suboptimal echocardiograms to assist in imaging theleft ventricular chamber and left endocardial border of the heart in ultrasound procedures. We launched DEFINITY in 2001, and its last patent in the UnitedStates will currently expire in 2021 and in numerous foreign jurisdictions in 2019. We also have an active next generation program for this agent.TechneLite is a technetium generator which provides the essential nuclear material used by radiopharmacies to radiolabel Cardiolite, Neurolite andother technetium-based radiopharmaceuticals used in nuclear medicine procedures. TechneLite uses Molybdenum-99, or Moly, as its main active ingredient.Xenon is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also for imaging cerebral blood flow. Xenon ismanufactured by a third party and packaged by us.Sales of our contrast agent, DEFINITY, are made in the United States and Canada through our sales team of approximately 80 employees. In the UnitedStates, our nuclear imaging products, including TechneLite, Xenon, Cardiolite and Neurolite, are primarily distributed through commercial radiopharmacies,the majority of which are controlled by or associated with Cardinal, UPPI, GE Healthcare and Triad. A small portion of our nuclear imaging product sales inthe United States are made through our direct sales force to hospitals and clinics that maintain their own in-house radiopharmaceutical capabilities. Outsidethe fifty United States, we own two 59 Table of Contentsradiopharmacies in Australia and one in Puerto Rico. In Europe, Asia Pacific and Latin America, we rely on third party distributors to market, sell anddistribute our nuclear imaging and contrast agent products, either on a country-by-country basis or on a multicountry regional basis.The following table sets forth our revenue derived from our principal products: Year Ended December 31, (dollars in thousands) 2015 % 2014 % 2013 % DEFINITY $111,859 38.1 $95,760 31.8 $78,094 27.5 TechneLite 72,562 24.7 93,588 31.0 92,195 32.5 Xenon 48,898 16.7 36,549 12.1 32,125 11.3 Other 60,142 20.5 75,703 25.1 81,258 28.7 Revenues $293,461 100.0 $301,600 100.0 $283,672 100.0 Key Factors Affecting Our ResultsOur business and financial performance have been, and continue to be, affected by the following:Growth of DEFINITYWe believe the market opportunity for our contrast agent, DEFINITY, remains significant. DEFINITY is currently our fastest growing and highestmargin commercial product. We believe that DEFINITY sales will continue to grow and that DEFINITY will constitute a greater share of our overall productmix. As we better educate the physician and healthcare provider community about the benefits and risks of this product, we believe we will experience furtherpenetration of suboptimal echocardiograms.Prior to the supply issues with BVL in 2012, sales of DEFINITY continually increased year-over-year since June 2008, when the boxed warning onDEFINITY was modified. Unit sales of DEFINITY had decreased substantially in late 2007 and early 2008 as a result of an FDA request in October 2007 thatwe and GE Healthcare, which distributes Optison, a competitor to DEFINITY, add a boxed warning to their products to notify physicians and patients aboutpotentially serious safety concerns or risks posed by the products. However, in May 2008, the FDA boxed warning was modified in response to thesubstantial advocacy efforts of prescribing physicians. In October 2011, we received FDA approval of further modifications to the DEFINITY label,including: further relaxing the boxed warning; eliminating the sentence in the Indication and Use section “The safety and efficacy of DEFINITY withexercise stress or pharmacologic stress testing have not been established” (previously added in October 2007 in connection with the imposition of the boxwarning); and including summary data from the post-approval CaRES (Contrast echocardiography Registry for Safety Surveillance) safety registry and thepost-approval pulmonary hypertension study. Bracco’s ultrasound contrast agent, Lumason, has substantially similar safety labeling as DEFINITY andOptison. The future growth of our DEFINITY sales will be dependent on our ability to continue to increase segment penetration for DEFINITY in suboptimalechocardiograms and, as discussed below in “—Inventory Supply,” on the ability of JHS, and, if approved Pharmalucence, to continue to manufacture andrelease DEFINITY on a timely and consistent basis. See “Item 1A—Risk Factors—The growth of our business is substantially dependent on increased marketpenetration for the appropriate use of DEFINITY in suboptimal echocardiograms.”There are three echocardiography contrast agents approved by the FDA for sale in the U.S.—DEFINITY which as of December 2015 had anapproximately 78% segment share, Optison, and Lumason, which was approved by the FDA in October 2014. Lumason is known as SonoVue outside of theU.S. and is already approved for sale in Europe and certain Asian markets, including China, Japan and Korea. While we believe that additional promotion inthe U.S. echocardiography segment will help raise awareness around the value that echocardiography contrast brings and potentially increase the overallcontrast penetration rate, if Bracco 60 Table of Contentssuccessfully commercializes Lumason in the U.S. without otherwise increasing the overall usage of ultrasound contrast agents, our own growth expectationsfor DEFINITY revenue, gross profit and gross margin may have to be adjusted.Competition for XenonXenon gas for lung ventilation diagnosis is our third largest product by revenue. Historically, several companies sold packaged Xenon as a pulmonaryimaging agent in the U.S., but since 2010 we have been the only supplier of this imaging agent in the U.S. We understand that a radiopharmaceuticalmanufacturer is now seeking regulatory approval from the FDA to sell packaged Xenon in the U.S. If that manufacturer receives FDA approval and begins tosell packaged Xenon in the U.S., depending upon the pricing, extent of availability and market penetration of the new offering, we believe we are at risk forvolume loss and price erosion for those customers which are not subject to price or volume commitments. In order to increase the predictability of our Xenonbusiness, we have entered into Xenon supply agreements at committed volumes and substantially reduced prices with previously non-contracted customers.These steps should result in more predictable Xenon unit volumes in 2016 at substantially lower revenue and gross margin contributions as compared to2015. See “Item 1A—Risk Factors—We face potential supply and demand challenges for Xenon.”Global Isotope SupplyCurrently, our largest supplier of Moly and our only supplier of Xenon is Nordion, which relies on the NRU reactor in Chalk River, Ontario. For Molyand Xenon, we have supply agreements with Nordion that expire on October 31, 2016, and for moly, supply agreements with NTP of South Africa, ANSTO ofAustralia, and IRE of Belgium, each running through December 31, 2017. The Canadian government requires the NRU reactor to shut down for at least fourweeks at least once a year for inspection and maintenance. The 2015 shutdown period ran from April 13, 2015 until May 13, 2015, and we were able tosource all of our standing order customer demand for Moly during this time period from our other suppliers. However, because Xenon is a by-product of theMoly production process and is currently captured only by Nordion, during this shutdown period, we were not able to supply all of our standing ordercustomer demand for Xenon during the outage. Because the month-long NRU shutdown was fully anticipated in our 2015 budgeting process, the shutdowndid not have a material adverse effect on our 2015 results of operations, financial condition and cash flows.We believe we are well-positioned with our current supply partners to have a secure supply of Moly, including low-enriched uranium, or LEU, Moly,when the NRU reactor transitions in October 2016 from providing regular supply of medical isotopes to providing only emergency back-up supply of HEUbased medical isotopes through March 2018. ANSTO has under construction, in cooperation with NTP, a new Moly processing facility that ANSTO believeswill expand its production capacity by approximately 2.5 times, with expanded commercial production planned to start in the latter part of 2016. In addition,IRE recently received approval from its regulator to expand its production capability by up to 50% of its former capacity. The new ANSTO and IREproduction capacity is expected to replace the NRU’s current routine production. In January 2015, we announced entering into a new strategic agreementwith IRE for the future supply of Xenon. Under the terms of the agreement, IRE will provide bulk Xenon to us for processing and finishing once developmentwork has been completed and all necessary regulatory approvals have been obtained. We currently estimate commercial production will occur in 2016. If weare not able to begin providing commercial quantities of Xenon prior to the NRU reactor’s supply transition in 2016, there may be a period of time duringwhich we are not able to offer Xenon in our portfolio of commercial products. See “Risk Factors—We face potential supply and demand challenges forXenon.”Inventory SupplyOur products consist of contrast imaging agents and radiopharmaceuticals (including technetium generators). We obtain a substantial portion of ourimaging agents from third party suppliers. JHS is currently 61 Table of Contentsour sole source manufacturer of DEFINITY, Neurolite and evacuation vials, an ancillary component for our TechneLite generators, and we have ongoingtechnology transfer activities at JHS for our Cardiolite product supply. In the meantime, our Cardiolite product supply is approved for manufacture by asingle manufacturer. Until JHS is approved by certain foreign regulatory authorities to manufacture certain of our products, we will face continued limitationson where we can sell those products outside of the United States.In addition to JHS, we are also currently working to secure additional alternative suppliers for our key products as part of our ongoing supply chaindiversification strategy. On November 12, 2013, we entered into a Manufacturing and Supply Agreement with Pharmalucence to manufacture and supplyDEFINITY. We currently anticipate that we will file for FDA approval in 2016 to manufacture DEFINITY at Pharmalucence.Radiopharmaceuticals are decaying radioisotopes with half-lives ranging from a few hours to several days. These products cannot be kept in inventorybecause of their limited useful lives and are subject to just-in-time manufacturing, processing and distribution, which takes place at our North Billerica,Massachusetts facility.Demand for TechneLiteSince the global Moly supply shortage in 2009 to 2010, we have experienced reduced demand for TechneLite generators from pre-shortage levels eventhough volume has increased in absolute terms from levels during the shortage following the return of our normal Moly supply in August 2010. However, wedo not know if overall industry demand for technetium will ever return to pre-shortage levels. See “Risk Factors—The Moly supply shortage caused by the2009-10 NRU reactor shutdown has had a negative effect on the demand for some of our products, which will likely continue in the future.”Separate from the Moly supply shortage, we believe there has also been a decline in the MPI study market because of industry-wide cost containmentinitiatives that have resulted in a transition of where imaging procedures are performed, from free-standing imaging centers to the hospital setting. While thetotal number of patient studies has not returned to pre-shortage levels, the total MPI market has been essentially flat for the period 2011 through 2014.In November 2015, CMS announced the 2016 final Medicare payment rules for hospital outpatient settings. Under the final rules, each technetiumdose produced from a generator for a diagnostic procedure in a hospital outpatient setting is reimbursed by Medicare at a higher rate if that technetium doseis produced from a generator containing Moly sourced from at least 95 percent LEU. In January 2013, we began to offer a TechneLite generator whichcontains Moly sourced from at least 95 percent LEU and which satisfies the requirements for reimbursement under this incentive program. Although demandfor LEU generators appears to be growing, we do not know when, or if, this incremental reimbursement for LEU Moly generators will result in a materialincrease in our generator sales.Cardinal Supply AgreementsOur written supply agreements with Cardinal relating to TechneLite, Xenon, Neurolite, Cardiolite and certain other products expired in accordancewith their terms on December 31, 2014. Following extended discussions with Cardinal, on November 19, 2015, we entered into a new contract for thedistribution of TechneLite, Xenon, Neurolite and other products beginning in 2015 through 2017. The agreement specifies pricing levels and requirements topurchase minimum volumes of certain products during certain periods. The agreement, which expires on December 31, 2017, may be terminated upon theoccurrence of specified events, including a material breach by the other party and certain force majeure events. From January 1, 2015 until the signing of thenew agreement on November 19, 2015, we continued to accept and fulfill product orders from this major customer on a purchase order basis at supply price.In 2016, we expect to sell a broader mix of products to Cardinal at lower contracted pricing than the pricing in effect for most of 2015, resulting inhigher revenues but lower gross margins than in most of 2015. 62 Table of ContentsResearch and Development ExpensesTo remain a leader in the marketplace, we have historically made substantial investments in new product development. As a result, the positivecontributions of those internally funded R&D programs have been a key factor in our historical results and success. In March 2013, we began to implement astrategic shift in how we will fund our important R&D programs. We have reduced our internal R&D resources while at the same time we are seeking toengage strategic partners to assist us in the further development and commercialization of our important agents in development, including flurpiridaz F 18,18F LMI 1195 and LMI 1174. As a result of this shift, we are seeking strategic partners to assist us with the further development and possiblecommercialization of flurpiridaz F 18. For our other two important agents in development, 18F LMI 1195 and LMI 1174, we are also seeking to engagestrategic partners to assist us with the ongoing development activities relating to these agents.SegmentsWe report our results of operations in two operating segments: United States and International. We generate a greater proportion of our revenue and netincome in the United States segment, which consists of all regions of the United States with the exception of Puerto Rico.Operating ResultsThe following have been included in our results for the year ended December 31, 2015: • increased revenues and segment penetration for DEFINITY in the suboptimal echocardiogram segment as a result of our sales efforts andsustained availability of product supply; • decreased revenues for TechneLite as a result of lower volumes; • increased revenues for Xenon, mainly the result of higher selling prices, offset in part by mix shift among certain sales channels; • increased revenues resulting from the return of Neurolite product supply; • decreased revenues from our Cardiolite products resulting from continued generic competition; • decreased international revenues resulting from unfavorable foreign exchange; • lower material costs incurred for the production of TechneLite; • $15.5 million loss on extinguishment of debt costs related to the redemption of LMI’s outstanding Notes; • $6.5 million payment for the termination of our advisory services and monitoring agreement with Avista; and • decreased interest expense due to the refinancing of long-term debt. 63 Table of ContentsYears Ended December 31, 2015, 2014 and 2013 December 31, 2015 comparedto 2014 2014 comparedto 2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% Revenues $293,461 $301,600 $283,672 $(8,139) (2.7)% $17,928 6.3% Cost of goods sold 157,939 176,081 206,311 (18,142) (10.3) (30,230) (14.7) Gross profit 135,522 125,519 77,361 10,003 8.0 48,158 62.3 Operating expenses Sales and marketing expenses 34,740 35,116 35,227 (376) (1.1) (111) (0.3) General and administrative expenses 43,894 37,313 33,036 6,581 17.6 4,277 12.9 Research and development expenses 14,358 13,673 30,459 685 5.0 (16,786) (55.1) Proceeds from manufacturer — — (8,876) — — 8,876 (100.0) Impairment on land — — 6,406 — — (6,406) (100.0) Total operating expenses 92,992 86,102 96,252 6,890 8.0 (10,150) (10.5) Operating income (loss) 42,530 39,417 (18,891) 3,113 7.9 58,308 308.7 Interest expense (38,715) (42,288) (42,915) 3,573 (8.4) 627 1.5 Interest income 24 27 104 (3) (11.1) (77) (74.0) Loss on extinguishment of debt (15,528) — — (15,528) (100.0) — — Other income (expense), net (89) 478 1,161 (567) (118.6) (683) (58.8) Income (loss) before income taxes (11,778) (2,366) (60,541) (9,412) 397.8 58,175 (96.1) Provision for income taxes 2,968 1,195 1,014 1,773 148.4 181 17.9 Net loss $(14,746) $(3,561) $(61,555) $(11,185) 314.1% $57,994 (94.2)% 64 Table of ContentsComparison of the Years Ended December 31, 2015, 2014, and 2013RevenuesRevenues are summarized as follows: Year ended December 31, 2015 comparedto 2014 2014 comparedto 2013 2015 2014 2013 Change$ Change% Change$ Change% (dollars in thousands) United States DEFINITY $109,656 $93,848 $76,539 $15,808 16.8% $17,309 22.6% TechneLite 62,034 82,321 80,609 (20,287) (24.6) 1,712 2.1 Xenon 48,868 36,542 32,086 12,326 33.7 4,456 13.9 Other 15,266 23,809 24,405 (8,543) (35.9) (596) (2.4) Total U.S. revenues $235,824 $236,520 $213,639 $(696) (0.3)% $22,881 10.7% International DEFINITY $2,203 $1,912 $1,555 $291 15.2% $357 23.0% TechneLite 10,528 11,267 11,586 (739) (6.6) (319) (2.8) Xenon 30 7 39 23 328.6 (32) (82.1) Other 44,876 51,894 56,853 (7,018) (13.5) (4,959) (8.7) Total International revenues $57,637 $65,080 $70,033 $(7,443) (11.4) $(4,953) (7.1) Revenues $293,461 $301,600 $283,672 $(8,139) (2.7)% $17,928 6.3% 2015 v. 2014Total revenues decreased $8.1 million, or 2.7%, to $293.5 million in the year ended December 31, 2015, as compared to $301.6 million in the yearended December 31, 2014. U.S. segment revenue decreased $0.7 million, or 0.3%, to $235.8 million in the same period, as compared to $236.5 million in theprior year. The U.S. segment decrease is primarily due to a decrease of $20.3 million in TechneLite revenues driven by lower volumes, a decrease in licenserevenue of approximately of $3.9 million as a result of a contract ending in December 2014 that had contained a license fee that was recognized on a straight-line basis over the term of the agreement, $1.5 million in Neurolite revenues driven by lower volumes and $1.8 million in Thallium revenues driven by lowervolumes. Offsetting these decreases was an increase of $15.8 million in DEFINITY revenues driven primarily by higher unit volumes and an increase of $12.3million in Xenon revenues primarily as a result of higher selling prices.International segment revenues decreased $7.4 million, or 11.4%, to $57.6 million in the year ended December 31, 2015, as compared to $65.1 millionin the year ended December 31, 2014. The decrease in the International segment revenue during the year ended December 31, 2014, as compared to the prioryear period, is primarily due to $6.8 million unfavorable foreign exchange and $2.2 million decrease in Cardiolite revenues as a result of competitivepressures. This was offset, in part, by $0.6 million in DEFINITY revenues driven by increased volume, $0.6 million increase in TechneLite revenues driven byvolumes and $0.3 million in other marketed products.2014 v. 2013Total revenues increased $17.9 million, or 6.3%, to $301.6 million in the year ended December 31, 2014, as compared to $283.7 million in the yearended December 31, 2013. U.S. segment revenue increased $22.9 million, or 10.7%, to $236.5 million in the same period, as compared to $213.6 million inthe prior year. The U.S. segment increase is primarily due to a $17.3 million increase in DEFINITY revenues as a result of higher unit 65 Table of Contentsvolumes, a $6.8 million increase in Neurolite revenues as the product returned to market in September 2013, a $4.5 million increase in Xenon revenuesprimarily due to higher selling prices, a $1.9 million increase in Thallium revenues driven by higher unit volumes with significant customer and $1.7 millionTechneLite revenues increase as a result of higher unit volumes. Offsetting these increases was a decrease in Cardiolite revenues of $5.3 million over the prioryear period as a result of a contract with a significant customer that reduced unit pricing and volume commitments and a $3.4 million decrease in Quadrametrevenues due to lower unit volume as a result of increased competitive pressures since we transitioned to being the direct manufacturer at the end of 2013.International segment revenues decreased $5.0 million, or 7.1%, to $65.1 million in the year ended December 31, 2014, as compared to $70.0 millionin the year ended December 31, 2013. The decrease in the International segment revenue during the year ended December 31, 2014, as compared to the prioryear period, is primarily due to $3.5 million unfavorable foreign exchange, combined with a $2.3 million decrease in third party product revenues and a $1.1million decrease in Cardiolite revenues as a result of competitive pressures in our international markets. Offsetting these decreases were a $1.0 millionincrease in Neurolite revenues driven by the return of finished product to the market, $0.4 million increase in TechneLite revenues primarily in the LatinAmerica market and $0.5 million increase in DEFINITY revenues as a result of sales volume growth in certain international markets.Rebates and AllowancesEstimates for rebates and allowances represent our estimated obligations under contractual arrangements with third parties. Rebate accruals andallowances are recorded in the same period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liability which isincluded in accrued expenses. These rebates result from performance-based offers that are primarily based on attaining contractually specified sales volumesand growth, Medicaid rebate programs for certain products, administrative fees of group purchasing organizations, royalties and certain distributor relatedcommissions. The calculation of the accrual for these rebates and allowances is based on an estimate of the third party’s buying patterns and the resultingapplicable contractual rebate or commission rate(s) to be earned over a contractual period.An analysis of the amount of, and change in, reserves is summarized as follows: (in thousands) Rebates Allowances Total Balance, as of January 1, 2013 $1,542 $66 $1,608 Current provisions relating to revenues in current year 4,696 243 4,939 Adjustments relating to prior years’ estimate (21) — (21) Payments/credits relating to revenues in current year (3,438) (220) (3,658) Payments/credits relating to revenues in prior years (1,040) (69) (1,109) Balance, as of December 31, 2013 1,739 20 1,759 Current provisions relating to revenues in current year 5,773 310 6,083 Adjustments relating to prior years’ estimate (18) — (18) Payments/credits relating to revenues in current year (4,264) (284) (4,548) Payments/credits relating to revenues in prior years (1,066) (20) (1,086) Balance, as of December 31, 2014 2,164 26 2,190 Current provisions relating to revenues in current year 6,413 357 6,770 Adjustments relating to prior years’ estimate (84) (9) (93) Payments/credits relating to revenues in current year (4,784) (319) (5,103) Payments/credits relating to revenues in prior years (1,406) (17) (1,423) Balance, as of December 31, 2015 $2,303 $38 $2,341 66 Table of ContentsSales rebates accrued were approximately $2.3 million and $2.2 million at December 31, 2015 and 2014, respectively. The $0.1 million increase inaccrued sales rebates is primarily related to the increase in the rebate reserve associated with the Quadramet product.Cost of Goods SoldCost of goods sold consists of manufacturing, distribution, intangible asset amortization and other costs related to our commercial products. Inaddition, it includes the write-off of excess and obsolete inventory.Cost of goods sold is summarized as follows: Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% United States $106,982 $127,237 $149,018 $(20,255) (15.9)% $(21,781) (14.6)% International 50,957 48,844 57,293 2,113 4.3 (8,449) (14.7) Total Cost of Goods Sold $157,939 $176,081 $206,311 $(18,142) (10.3)% $(30,230) (14.7)% 2015 v. 2014Total cost of goods sold decreased $18.1 million, or 10.3%, to $157.9 million in the year ended December 31, 2015, as compared to $176.1 million inthe year ended December 31, 2014. U.S. segment cost of goods sold decreased approximately $20.3 million, or 15.9%, to $107.0 million in same period, ascompared to $127.2 million in the prior year period. The decrease in the U.S. segment cost of goods sold for the year ended December 31, 2015 over the prioryear period is primarily due to a decrease of $18.2 million in the cost of goods associated with TechneLite due to lower sales unit volumes. In addition, therewas a $2.8 million decrease in Neurolite cost of goods due to lower unit volumes sold and lower technology transfer costs. We also incurred a decrease of$4.8 million in Thallium cost of goods due to lower unit volumes sold. Offsetting these decreases was a $4.5 million increase in DEFINITY cost of goods dueto higher sales unit volumes and a $2.7 million increase in Xenon cost of goods due to an increase in material, labor and overhead costs.For the year ended December 31, 2015, the International segment cost of goods sold increased $2.1 million, or 4.3%, to $51.0 million, as compared to$48.8 million in the prior year period. The increase in the International segment cost of goods sold during the year ended December 31, 2015, as compared tothe prior year period, is primarily due to approximately $5.8 million in product cost pricing increases. Partially offsetting these increases was a $3.5 millionfavorable foreign exchange impact.2014 v. 2013Total cost of goods sold decreased $30.2 million, or 14.7%, to $176.1 million in the year ended December 31, 2014, as compared to $206.3 million inthe year ended December 31, 2013.

The decrease in the U.S. segment cost of goods sold for the year ended December 31, 2014 over the prioryear period is primarily due to a $22.0 million decrease in Cardiolite cost of goods as a result of a $15.4 million write-down in the Cardiolite trademarkintangible asset in the fourth quarter of 2013 and lower amortization expense in 2014 as compared to 2013 as a result of the impairment. In addition, therewas a $2.8 million decrease in TechneLite cost of goods sold primarily due to lower material costs for 2014. We also incurred $2.1 million of lower write-offexpense as compared to the prior year related to the Ablavar product line. Offsetting these decreases was a $5.9 million increase in DEFINITY and Thalliumcost of goods sold due to higher sales unit volumes and higher DEFINITY technology transfer costs. 67 Table of ContentsFor the year ended December 31, 2014, the International segment cost of goods sold decreased $8.5 million, or 14.7%, to $48.8 million, as compared to$57.3 million in the prior year period. The decrease in the International segment cost of goods sold during the year ended December 31, 2014, as compared tothe prior year period, is primarily due to a $4.5 million decrease as a result of reduced costs associated with operating efficiencies as well as lower cost ofgoods sold for certain products. We also incurred an impairment charge of $1.7 million in the prior year relating to customer relationship intangible assets inEurope, lower amortization expense in the current year and a $1.7 million favorable foreign exchange impact.Gross Profit Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% United States $128,842 $109,283 $64,621 $19,559 17.9% $44,662 69.1% International 6,680 16,236 12,740 (9,556) (58.9) 3,496 27.4 Total Gross Profit $135,522 $125,519 $77,361 $10,003 8.0% $48,158 62.3% 2015 v. 2014Total gross profit increased $10.0 million, or 8.0%, to $135.5 million, or 46.2% of revenues in the year ended December 31, 2015, as compared to$125.5 million or 41.6% of revenues in the year ended December 31, 2014. U.S. segment gross profit increased $19.6 million, or 17.9%, to $128.8 million, ascompared to $109.3 million in the prior year period. The increase in the U.S. segment gross profit for the year ended December 31, 2015 over the prior yearperiod is primarily due to an increased DEFINITY gross profit of $11.3 million due to higher unit volumes and Xenon gross profit increased $9.6 million dueto higher selling price. In addition, Thallium gross profit increased by $3.0 million primarily due to a higher average selling price and Neurolite gross profitincreased by $1.3 million due to lower technology transfer costs. Offsetting these increases was a decrease in license revenue of $3.7 million as a result of acontract ending in December 2014 that had contained a license fee that was recognized on a straight-line basis over the term of the agreement and a decreaseof $2.0 million in TechneLite gross profit due to lower sales unit volumes.For the year ended December 31, 2015, the International segment gross profit decreased $9.6 million, or 58.9%, to $6.7 million, as compared to $16.2million in the prior year period. The decrease in the International segment gross profit during the year ended December 31, 2015, as compared to the prioryear period is primarily due to $3.3 million unfavorable foreign exchange impact, combined with approximately $5.6 million product cost pricing increases,as well as $0.7 million driven by lower sales volume in certain international markets.2014 v. 2013Total gross profit increased $48.2 million, or 62.3%, to $125.5 million, or 41.6% of revenues in the year ended December 31, 2014, as compared to$77.4 million or 27.3% of revenues in the year ended December 31, 2013. U.S. segment gross profit increased $44.7 million, or 69.1%, to $109.3 million, ascompared to $64.6 million in the prior year period. The increase in the U.S. segment gross profit for the year ended December 31, 2014 over the prior yearperiod is primarily due to a $16.6 million increase in Cardiolite gross profit due to a write-down in the Cardiolite trademark intangible asset in the fourthquarter of 2013 and a $25.1 million aggregate increase in DEFINITY, TechneLite and Neurolite gross profit due to higher unit volumes and lower materialcosts for TechneLite. In addition, Xenon gross profit increased by $4.1 million due to higher selling price. Offsetting these increases was a $3.8 milliondecrease in Quadramet gross profit due to less unit volume since we transitioned as the direct manufacturer at the end of 2013. 68 Table of ContentsFor the year ended December 31, 2014, the International segment gross profit increased $3.5 million, or 27.4%, to $16.2 million, as compared to $12.7million in the prior year period. The increase in the International segment gross profit during the year ended December 31, 2014, as compared to the prioryear period is primarily due to a $1.7 million impairment charge on customer relationship intangible assets in the prior year and lower amortization ascompared to the prior year. The increase is also driven by reduced costs associated with increased operating efficiencies, the return of Neurolite finishedproduct to the market and lower volume of more expensive substitute products sold in the current period as a result of the return of supply. These increaseswere partially offset by an unfavorable foreign exchange impact of $1.8 million.Sales and Marketing Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% United States $31,130 $30,815 $31,024 $315 1.0% $(209) (0.7)% International 3,610 4,301 4,203 $(691) (16.1) 98 2.3 Total Sales and Marketing $34,740 $35,116 $35,227 $(376) (1.1)% $(111) (0.3)% Sales and marketing expenses consist primarily of salaries and other related costs for personnel in field sales, marketing, business development andcustomer service functions.

In the U.S. segment, general and administrative expenses increased $7.1 million, or 20.3%,to $42.1 million, as compared to $35.0 million in the prior year period. The increase was primarily due to the $6.5 million termination fee paid to terminatethe advisory services and monitoring agreement with Avista, increased stock compensation costs, increases in insurance associated with the initial publicoffering in June 2015, higher software amortization expense and an increase in our provision for bad debt. This was offset by higher costs in the prior perioddue to a $2.4 million write-off of deferred initial public offering costs and $1.0 million higher legal fees related to business interruption claim.For the year ended December 31, 2015, general and administrative expenses in the International segment decreased approximately $0.5 million, or22%, to $1.8 million, as compared to $2.3 million in the prior year period.

In the U.S. segment, general and administrative expenses increased $4.3 million, or 13.9%,to $35.0 million, as compared to $30.7 million in the prior year period. The increase was primarily due to the write-off of deferred offering costs during thethird quarter of 2014 and employee related expenses. Offsetting these increases were non-recurrence of severance expense related to the reduction in force inthe first quarter of 2013, decrease in depreciation expense and cost savings achieved through the renegotiation of certain information technology relatedcontracts.For the year ended December 31, 2014, general and administrative expenses in the International segment remained relatively consistent as compared tothe prior year period. 70 Table of ContentsResearch and Development Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% United States $13,613 $13,252 $30,138 $361 2.7% $(16,886) (56.0)% International $745 421 321 324 76.9 100 31.2 Total Research and Development $14,358 $13,673 $30,459 $685 5.0% $(16,786) (55.1)% Research and development expenses relate primarily to the development of new products to add to our portfolio and costs related to medical affairs,medical information and regulatory functions. We do not allocate research and development expenses incurred in the United States to our Internationalsegment.2015 v. 2014Total research and development expense increased $0.7 million, or 5.0%, to $14.4 million for the year ended December 31, 2015, as compared to $13.7million in the year ended December 31, 2014. In the U.S. segment, research and development expense increased approximately $0.4 million, or 2.7%, to$13.6 million, as compared to $13.3 million in the prior year period. The increase in the U.S. segment research and development expenses is primarily due toan increase of depreciation expense as a result of the scheduled decommissioning of certain long-lived assets associated with R&D operations, a gain in theprior year associated with the sale of certain long-lived assets and change in headcount, offset by a reduction in overhead costs associated with thedecommissioning of certain long-lived assets.For the year ended December 31, 2015, the International segment research and development expenses increased approximately $0.3 million, 76.9%, to$0.7 million, as compared to $0.4 million in the prior year period. The increase in research and development expenses for the International segment wasprimarily due to increased regulatory costs.2014 v. 2013Total research and development expense decreased $16.8 million, or 55.1%, to $13.7 million for the year ended December 31, 2014, as compared to$30.5 million in the year ended December 31, 2013. In the U.S. segment, research and development expense decreased approximately $16.9 million, or56.0%, to $13.3 million, as compared to $30.1 million in the prior year period. The decrease in the U.S. segment research and development expenses isprimarily due to a decline in external expense associated with Phase 3 clinical trial for flurpiridaz F 18 as we completed patient enrollment during the thirdquarter of 2013. In addition, there were decreases in employee related costs as a result of the reduction in workforce from a strategic shift to use fewer internalresources and lower external expense as we expect to seek one or more strategic partners to assist in the future development and commercialization of ouragents in development. Offsetting this decrease was a $0.9 million increase in depreciation expense as we announced in November 2014 our plans todecommission certain long-lived assets associated with our research and development operations in the United States. We expected the decommissioning tobegin in the second half of 2015. As a result, we revised our estimates of the remaining useful lives of the affected long-lived assets to seven months, whichincreased depreciation expense by $1.2 million and is included in research and development expenses.For the year ended December 31, 2014, the International segment research and development expenses increased approximately $0.1 million, or 31.2%,to $0.4 million, as compared to $0.3 million in the prior year period. The increase in research and development expenses for the International segment wasprimarily due to depreciation expense since we shifted the primary utilization of certain assets to support research and development functions. 71 Table of ContentsImpairment of LandDuring the third quarter of 2013, we committed to a plan to sell certain of our excess land, which had a carrying value of $7.5 million. This eventqualified for held for sale accounting and the excess land was written down to its fair value, less costs to sell. The fair value was estimated utilizing Level 3inputs and using a market approach, based on available data for transactions in the region as well as the asking price of comparable properties in our principalmarket. This resulted in a loss of $6.4 million, which is included within operating income (loss) as impairment of land in the accompanying consolidatedstatement of operations. During the fourth quarter of 2013, we sold the excess land for net proceeds of $1.1 million.Proceeds from ManufacturerFor the year ended December 31, 2013, we received $8.9 million from BVL to compensate us for business losses under a 2013 settlement.Other Income (Expense), Net Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% Interest expense $(38,715) $(42,288) $(42,915) $3,573 (8.4)% $627 (1.5)% Interest income 24 27 104 (3) (11.1) (77) (74.0) Loss on extinguishment of debt (15,528) — — (15,528) (100.0) — — Other income (expense), net (89) 478 1,161 (567) (118.6) (683) (58.8) Total Other Expense, net $(54,308) $(41,783) $(41,650) $(12,525) 30.0% $(133) 0.3% Interest ExpenseFor the year ended December 31, 2015 compared to the same period in 2014, interest expense decreased by 8.4% to $38.7 million from $42.3 million,as a result of the refinancing of long-term debt offset by a $3.3 million interest payment made for interest through the redemption date (July 30, 2015) on theSenior Notes.For the year ended December 31, 2014 compared to the same period in 2013, interest expense decreased by 1.5% to $42.3 million from $42.9 million,as a result of decreased amortization related to deferred financing costs.Interest IncomeFor the year ended December 31, 2015, as compared to the same period in 2014, interest income remained consistent.For the year ended December 31, 2014, as compared to the same period in 2013, interest income decreased by 74.0% to $27,000 from $104,000,primarily as a result of the change in balances in interest bearing accounts.Extinguishment of DebtFor the year ended December 31, 2015, we incurred a $15.5 million loss on extinguishment of debt related to the redemption of LMI’s Notes. Forinformation regarding our loss on extinguishment of debt, see Note 11, “Financing Arrangements” to our consolidated financial statements. 72 Table of ContentsOther Income (Expense), netFor the year ended December 31, 2015, as compared to the same period in 2014, other income (expense), net decreased by 118.6% to $(0.1) millionfrom $0.5 million primarily due to a $1.5 million increase in foreign currency losses offset by a $0.9 million increase in tax indemnification income as aresult of settlement of state tax audits.For the year ended December 31, 2014, as compared to the same period in 2013, other income (expense), net decreased by $0.7 million from $1.2million primarily due to a net $1.2 million settlement indemnified by BMS during 2014.Provision for Income Taxes Year ended December 31, 2015 compared to2014 2014 compared to2013 (dollars in thousands) 2015 2014 2013 Change$ Change% Change$ Change% Provision for income taxes $2,968 $1,195 $1,014 $1,773 148.4% $181 17.9% For the year ended December 31, 2015 compared to the same period in 2014, provision for income taxes increased to $3.0 million from $1.2 million.Provision for income taxes increased in 2015 due to settlements and lapse of statute of limitations of uncertain tax positions in the current year.For the year ended December 31, 2014 compared to the same period in 2013, provision for income taxes increased to $1.2 million from $1.0 million.Provision for income taxes increased in 2014 due to changes in taxable income in certain foreign jurisdictions and settlements and lapse of statute oflimitations of uncertain tax positions in the current year.We have generated domestic pre-tax losses for two of the past three years and continue to be in a cumulative loss position. This loss historydemonstrates negative evidence concerning our ability to utilize our gross deferred tax assets. In order to overcome the presumption of recording a valuationallowance against our net deferred tax assets, we must have sufficient positive evidence that we can generate sufficient taxable income to utilize thesedeferred tax assets within the carryover or forecast period. Although we have no history of expiring net operating losses or other tax attributes, based on thecumulative domestic loss incurred over the three-year period ended December 31, 2015, management has determined that all of the net U.S. deferred taxassets are not more-likely-than-not recoverable. As a result of this analysis, we maintained a valuation allowance against substantially all of our net deferredtax assets in 2015.Considering our history of losses, our provision for income taxes results primarily from taxes due in certain foreign jurisdictions where we generatetaxable income, as well as interest and penalties associated with uncertain tax positions, offset by reversals of those positions as statutes lapse or are settledduring the year. Accordingly, fluctuations in our effective tax rate in recent years are not overly meaningful, or indications of on-going trends. Our effectivetax rates for the years ended December 31, 2015, 2014, and 2013 were, 25.2%, 50.5%, and 1.7%, respectively. Our tax rate is affected by recurring items, suchas tax rates in foreign jurisdictions, which we expect to be fairly consistent in the near term, as well as non-recurring items such as the settlement of stateaudits. The following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 35% and our effective taxrate during the years ended:December 31, 2015 • A $2.5 million increase attributable to uncertain tax positions. • A $0.5 million increase for taxes in foreign and state jurisdictions. 73 Table of ContentsDecember 31, 2014 • A $0.8 million increase attributable to prior year uncertain tax positions for a closed tax year. • A $0.4 million increase for taxes in foreign jurisdictions.December 31, 2013 • A $25.6 million increase to our valuation allowance against net domestic deferred tax assets. • A $1.5 million reduction relating primarily to prior year uncertain tax positions for a closed tax year. • A $1.8 million reduction primarily relating to a state income tax benefit related to state NOL’s.Liquidity and Capital ResourcesCash FlowsThe following table provides information regarding our cash flows: Year Ended December 31, % Change 2015 2014 2013 2015Comparedto 2014 2014Comparedto 2013 (dollars in thousands) Cash provided by (used in): Operating activities $21,762 $11,590 $(15,572) 87.8% 174.4% Investing activities (13,151) (7,682) (3,483) 71.2% 120.6% Financing activities 999 (2,297) 5,612 143.5% (140.9)% Net Cash Provided by (Used in) Operating ActivitiesCash provided by operating activities is primarily driven by our earnings and changes in working capital. Cash provided by operating activities during2015 increased by $10.2 million, which resulted from a decrease in net loss, as adjusted for non-cash items, in the amount of $6.6 million over the prior yearand a decrease in cash used for net working capital requirements in the amount of $3.6 million over the prior year. The $6.6 million increase in cash flowsfrom our net loss, as adjusted for non-cash items, was driven by an increased gross profit margin as compared to the prior year. The $3.6 million increase incash flows from our net working capital requirements was due to decreases in accounts receivable as a result of decreases in certain major customer balancesand decreases in accounts payable as a result of the timing of payments. The improvement in cash flows from our net working capital requirements waspartially offset by cash flow decreases in inventory due to timing of the receipt of inventory.The increase in cash provided by operating activities for the year ended December 31, 2014 as compared to 2013 was primarily driven by a decrease innet loss and cash flow increase for inventory purchases primarily due to timing of the receipt of inventory. The improvement was partially offset by cash flowdecreases in accounts receivable primarily due to increased revenues.Net Cash Used in Investing ActivitiesOur primary uses of cash in investing activities are for the purchase of property and equipment. Net cash used in investing activities in 2015, 2014 and2013 reflected the purchase of property and equipment for $13.1 million, $8.1 million and $5.0 million, respectively. 74 Table of ContentsNet Cash Provided by (Used in) Financing ActivitiesDuring the year ended December 31, 2015, we generated $421.3 million from the net proceeds of the Term Facility together with the net proceeds fromthe initial public offering. The net proceeds generated from the Term Facility and the initial public offering were used to repay in full the aggregate principalamount of the $400.0 million Notes, pay related premiums and expenses and pay down the $8.0 million of outstanding borrowings under the RevolvingFacility, which totaled $417.8 million. Net cash used in financing activities during 2014 was due to payments made for offering costs. Net cash provided byfinancing activities during 2013 was associated with an $8.0 million draw against our outstanding Revolving Facility.Historically, our primary source of cash flows from financing activities is draws against our outstanding Revolving Facility. Going forward, we expectour primary source of cash flows from financing activities to be similar draws against our Revolving Facility, issuances of stock or other financingarrangements into which we may enter. Our primary historical uses of cash in financing activities are principal payments on our term loan and RevolvingFacility as well as dividends to our shareholders. See “—External Sources of Liquidity.”External Sources of LiquidityOn June 30, 2015, we completed our initial public offering, entered into a new $365.0 million seven-year Term Facility and amended and restated ourRevolving Facility that has a borrowing capacity of $50.0 million. The net proceeds of the Term Facility and the initial public offering together withavailable cash were used to repay in full the aggregate principal amount of the $400.0 million Notes, and pay related premiums, interest and expenses andpay down $8.0 million of borrowings under the Revolving Facility.We have the right to request an increase of the Term Facility in an aggregate amount up to $37.5 million plus additional amounts subject to certainleverage ratios. The term loans under the Term Facility bear interest, with pricing based from time to time at our election at (i) LIBOR plus a spread of 6.00%(with a LIBOR rate floor of 1.00%) or (ii) the Base Rate (as defined in our Term Facility) plus a spread of 5.00%. Interest under term loans based on (i) theLIBOR rate is payable at the end of each interest period (as defined in our Term Facility) and (ii) the Base Rate is payable at the end of each quarter. AtDecember 31, 2015, our interest rate under the Term Facility was 7.00%. Our Term Facility is guaranteed by the Lantheus Holdings and Lantheus Real Estate,and obligations under the Term Facility are secured by substantially all the property and assets and all interests of Lantheus Holdings, LMI and LantheusReal Estate.Our Term Facility contains a number of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions andmateriality thresholds. Incremental borrowings under the Revolving Facility may affect our ability to comply with the covenants in the Term Facility,including the financial covenant restricting total net leverage, accordingly, we may be limited in utilizing our net Borrowing Base availability as a source ofliquidity. Our Term Facility requires us to be in quarterly compliance, measured on a trailing four quarter basis. The financial covenants are displayed in thetable below:Term Facility Financial Covenants Period Total Net Leverage Ratio Q3 2015 to Q1 2016 6.25 to 1.00 Q2 2016 to Q4 2016 6.00 to 1.00 Q1 2017 to Q2 2017 5.50 to 1.00 Thereafter 5.00 to 1.00 The Term Facility contains usual and customary restrictions on the ability of us and our subsidiaries to: (i) incur additional indebtedness (ii) createliens; (iii) consolidate, merge, sell or otherwise dispose of all or substantially all of our assets; (iv) sell certain assets; (v) pay dividends on, repurchase ormake distributions in respect of capital stock or make other restricted payments; (vi) make certain investments; (vii) repay subordinated indebtedness prior tostated maturity; and (viii) enter into certain transactions with our affiliates. 75 Table of ContentsAs of December 31, 2015, we had an unfunded Standby Letter of Credit of $8.8 million. The unfunded Standby Letter of Credit requires annual fees,payable quarterly, which, subsequent to the amendment, is set at LIBOR plus a spread of 2.00% and expired during February 2016. It automatically renewedfor a one year period and will continue to automatically renew for a one year period at each anniversary date, unless we elect not to renew in writing within60 days prior to such expiration.Our Revolving Facility is secured by a pledge of substantially all of the assets of LMI, together with the assets of the Company and assets of LantheusReal Estate, including each such entity’s accounts receivable, inventory and machinery and equipment, and is guaranteed by each of Lantheus Holdings andLantheus Real Estate. Borrowing capacity is determined by reference to a borrowing base, or the Borrowing Base, which is based on (i) a percentage of certaineligible accounts receivable, inventory and machinery and equipment minus (ii) any reserves. As of December 31, 2015, the aggregate Borrowing Base wasapproximately $48.2 million, which was reduced by an outstanding $8.8 million unfunded Standby Letter of Credit and $0.1 million in accrued interest,resulting in a net borrowing base availability of approximately $39.3 million.The loans under our Revolving Facility bear interest with pricing based from time to time at our election at (i) LIBOR plus a spread of 2.00% or (ii) theReference Rate (as defined in our Revolving Facility) plus a spread of 1.00%. Our Revolving Facility also includes an unused line fee of 0.375% and expireson June 30, 2020.Our Revolving Facility contains affirmative and negative covenants, as well as restrictions on the ability of LMI, us and our subsidiaries to: (i) incuradditional indebtedness or issue preferred stock; (ii) repay subordinated indebtedness prior to its stated maturity; (iii) pay dividends on, repurchase or makedistributions in respect of capital stock or make other restricted payments; (iv) make certain investments; (v) sell certain assets; (vi) create liens;(vii) consolidate, merge, sell or otherwise dispose of all or substantially all of our assets; and (viii) enter into certain transactions with our affiliates. OurRevolving Facility also contains customary default provisions as well as cash dominion provisions which allow the lender to sweep our accounts during theperiod (x) certain specified events of default are continuing under our Revolving Facility or (y) excess availability under our Revolving Facility falls below(i) the greater of $7.5 million or 15% of the then-current line cap (as defined in the Revolving Facility) for a period of more than five consecutive BusinessDays or (ii) $5.0 million. During a covenant trigger period, we are required to comply with a consolidated fixed charge coverage ratio of not less than 1: 00:1:00. The fixed charge coverage ratio is calculated on a consolidated basis for Lantheus Holdings and its subsidiaries for a trailing four-fiscal quarter periodbasis, as (i) EBITDA (as defined in the agreement) minus capital expenditures minus certain restricted payments divided by (ii) interest plus taxes paid orpayable in cash plus certain restricted payments made in cash plus scheduled principal payments paid or payable in cash.Our ability to fund our future capital needs will be affected by our ability to continue to generate cash from operations and may be affected by ourability to access the capital markets, money markets, or other sources of funding, as well as the capacity and terms of our financing arrangements.We may from time to time repurchase or otherwise retire our debt and take other steps to reduce our debt or otherwise improve our balance sheet. Theseactions may include open market repurchases of any notes outstanding, prepayments of our term loans or other retirements or refinancing of outstanding debt,privately negotiated transactions or otherwise. The amount of debt that may be repurchased or otherwise retired, if any, would be decided at the solediscretion of our Board of Directors and will depend on market conditions, trading levels of our debt from time to time, our cash position and otherconsiderations.Funding RequirementsOur future capital requirements will depend on many factors, including: • our ability to have product manufactured and released from JHS and other manufacturing sites in a timely manner in the future; • the pricing environment and the level of product sales of our currently marketed products, particularly DEFINITY and any additional productsthat we may market in the future; 76 Table of Contents • revenue mix shifts and associated volume and selling price changes that could result from contractual status changes with key customers andadditional competition; • the costs of further commercialization of our existing products, particularly in international markets, including product marketing, sales anddistribution and whether we obtain local partners to help share such commercialization costs; • the costs of investing in our facilities, equipment and technology infrastructure; • the costs and timing of establishing manufacturing and supply arrangements for commercial supplies of our products; • the extent to which we acquire or invest in products, businesses and technologies; • the extent to which we choose to establish collaboration, co- promotion, distribution or other similar arrangements for our marketed products; • the legal costs relating to maintaining, expanding and enforcing our intellectual property portfolio, pursuing insurance or other claims anddefending against product liability, regulatory compliance or other claims; and • the cost of interest on any additional borrowings which we may incur under our financing arrangements.Until we successfully become dual sourced for our principal products, we are vulnerable to future supply shortages. Disruption in the financialperformance could also occur if we experience significant adverse changes in customer mix, broad economic downturns, adverse industry or companyconditions or catastrophic external events. If we experience one or more of these events in the future, we may be required to implement additional expensereductions, such as a delay or elimination of discretionary spending in all functional areas, as well as scaling back select operating and strategic initiatives.See “Item 1A—Risk Factors—We may not be able to generate sufficient cash flow to meet our debt service obligations.”If our capital resources become insufficient to meet our future capital requirements, we would need to finance our cash needs through public or privateequity offerings, assets securitizations, debt financings, sale-leasebacks or other financing or strategic alternatives, to the extent such transactions arepermissible under the covenants of the agreements governing our senior secured credit facilities. Additional equity or debt financing, or other transactions,may not be available on acceptable terms, if at all. If any of these transactions require an amendment or waiver under the covenants in the agreementsgoverning our senior secured credit facilities, which could result in additional expenses associated with obtaining the amendment or waiver, we will seek toobtain such a waiver to remain in compliance with those covenants. However, we cannot be assured that such an amendment or waiver would be granted, orthat additional capital will be available on acceptable terms, if at all.At December 31, 2015, our only current committed external source of funds is our borrowing availability under our Revolving Facility. We generated anet loss of $14.7 million during the year ended December 31, 2015 and had $28.6 million of cash and cash equivalents at December 31, 2015. Availabilityunder our Revolving Facility is calculated by reference to the Borrowing Base. If we are not successful in achieving our forecasted results, our accountsreceivable and inventory could be negatively affected, reducing the Borrowing Base and limiting our borrowing availability. Our new Term Facility containsa number of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds. Incrementalborrowings under the Revolving Facility may affect our ability to comply with the covenants in the Term Facility, including the financial covenantrestricting total net leverage. Accordingly, we may be limited in utilizing our net Borrowing Base availability as a source of liquidity.Based on our current operating plans, we believe that our existing cash and cash equivalents, results of operations and availability under ourRevolving Facility will be sufficient to continue to fund our liquidity requirements for at least the next twelve months. 77 Table of ContentsContractual ObligationsContractual obligations represent future cash commitments and liabilities under agreements with third parties and exclude contingent contractualliabilities for which we cannot reasonably predict future payment, including contingencies related to potential future development, financing, certainsuppliers, contingent royalty payments and/or scientific, regulatory, or commercial milestone payments under development agreements. The following tablesummarizes our contractual obligations as of December 31, 2015: Payments Due by Period Total Less than1 Year 1 - 3 Years 3 -5 Years More than5 Years (dollars in thousands) Debt obligations (principal) $363,175 $3,650 $7,300 $7,300 $344,925 Interest on debt obligations(4) 160,054 25,326 49,886 48,864 35,978 Operating leases(1) 2,787 481 758 665 883 Other long-term liabilities(2) — — — — — Asset retirement obligations(3) — — — — — Total contractual obligations $526,016 $29,457 $57,944 $56,829 $381,786 (1)Operating leases include minimum payments under leases for our facilities and certain equipment.(2)Our other long-term liabilities in the consolidated balance sheet include unrecognized tax benefits and related interest and penalties. As ofDecember 31, 2015, we had unrecognized tax benefits of $33.8 million, which included interest and penalties, classified as noncurrent liabilities. Atthis time, we are unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with these tax liabilities;therefore, such amounts are not included in the above contractual obligation table.(3)We have excluded asset retirement obligations from the table above due to the uncertainty of the timing of the future cash outflows related to thedecommissioning of our radioactive operations. As of December 31, 2015, the liability, which was approximately $8.1 million, was measured at thepresent value of the obligation expected to be incurred, of approximately $26.6 million.(4)Amount relates to the minimum interest under the Term Facility.Off-Balance Sheet ArrangementsWe are required to provide the NRC and Massachusetts Department of Public Health financial assurance demonstrating our ability to fund thedecommissioning of our North Billerica, Massachusetts production facility upon closure, though we do not intend to close the facility. We have providedthis financial assurance in the form of a $28.2 million surety bond and an $8.8 million letter of credit.Since inception, we have not engaged in any other off-balance sheet arrangements, including structured finance, special purpose entities or variableinterest entities.Effects of InflationWe do not believe that inflation has had a significant impact on our revenues or results of operations since inception. We expect our cost of productsales and other operating expenses will change in the future in line with periodic inflationary changes in price levels. Because we intend to retain andcontinue to use our property and equipment, we believe that the incremental inflation related to the replacement costs of those items will not materially affectour operations. However, the rate of inflation affects our expenses, such as those for employee compensation and contract services, which could increase ourlevel of expenses and the rate at which we use our resources. While we generally believe that we will be able to offset the effect of price-level changes byadjusting our product prices and implementing operating efficiencies, any material unfavorable changes in price levels could have a material adverse affecton our financial condition, results of operations and cash flows. 78 Table of ContentsRecent Accounting StandardsWe have elected to “opt out” of the extended transition period for complying with new and revised accounting standards pursuant to Section 107 ofthe JOBS Act, and the election is irrevocable.In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) or ASU 2014-09. ASU 2014-09 supersedes nearlyall existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or servicesare transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines afive step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognitionprocess than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variableconsideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In August 2015, the FASBissued ASU 2015-14, Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date, which defers the effective date of ASU 2014-09 toannual reporting periods beginning after December 15, 2017 with early adoption permitted as of its original effective date of December 15, 2016. The newguidance requires either a retrospective or a modified retrospective approach to adoption. We are currently evaluating the impact this ASU will have on ourfinancial position, results of operations and cash flows.In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-4): Disclosure of Uncertaintiesabout an Entity’s Ability to Continue as a Going Concern or ASU 2014-15. ASU 2014-15 to provide guidance on management’s responsibility in evaluatingwhether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments inASU 2014-15 are effective for annual reporting periods ending after December 15, 2016. Early adoption is permitted. We do not anticipate this ASU will havea material impact to our financial position, results of operations or cash flows.Critical Accounting Policies and EstimatesThe discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have beenprepared in accordance with U.S. GAAP. These financial statements require us to make estimates and judgments that affect our reported assets and liabilities,revenues and expenses, and other financial information. Actual results may differ materially from these estimates under different assumptions and conditions.In addition, our reported financial condition and results of operations could vary due to a change in the application of a particular accounting standard.We believe the following represent our critical accounting policies and estimates used in the preparation of our financial statements.Revenue RecognitionOur revenue is generated from the sales of our diagnostic imaging agents to wholesalers, distributors, and radiopharmacies and directly to hospitals andclinics. We recognize revenue when evidence of an arrangement exists, title has passed, substantially all the risks and rewards of ownership have transferredto the customer, the selling price is fixed and determinable and collectability is reasonably assured. For transactions for which revenue recognition criteriahave not yet been met, the respective amounts are recorded as deferred revenue until that point in time when criteria are met and revenue can be recognized.Revenue is recognized net of reserves, which consist of allowances for returns and sales rebates. The estimates of these allowances are based on historicalsales volumes and mix and require assumptions and judgments to be made in order to make those estimates. In the event that the sales mix is different fromour estimates, we may be required to pay higher or lower returns and sales rebates than we previously estimated. Any changes to these estimates are recordedin the current period. In 2015, 2014 and 2013, these changes in estimates were not material to our results. 79 Table of ContentsRevenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the deliveredelement has stand-alone value to the customer. The arrangement’s consideration is then allocated to each separate unit of accounting based on the relativeselling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i) vendor-specificobjective evidence of fair value; (ii) third party evidence of selling price; and (iii) best estimate of selling price. The best estimate of selling price reflects ourbest estimate of what the selling price would be if the deliverable was regularly sold by us on a stand-alone basis. The consideration allocated to each unit ofaccounting is then recognized as the related goods or services are delivered, limited to the consideration that is not contingent upon future deliverables.Supply or service transactions may involve the charge of a nonrefundable initial fee with subsequent periodic payments for future products or services. Theup-front fees, even if nonrefundable, are earned (and revenue is recognized) as the products and/or services are delivered and performed over the term of thearrangement.InventoryInventories include material, direct labor and related manufacturing overhead, and are stated at the lower of cost or market determined on a first-in,first-out basis. We record inventory when we take title to the product. Any commitment for product ordered but not yet received is included as purchasecommitments in our contractual obligations table. We assess the recoverability of inventory to determine whether adjustments for impairment are required.Inventory that is in excess of future requirements is written down to its estimated net realizable value-based upon estimates of forecasted demand for ourproducts. The estimates of demand require assumptions to be made of future operating performance and customer demand. If actual demand is less than whathas been forecasted by management, additional inventory write downs may be required.Goodwill, Intangibles and Long-Lived AssetsGoodwill is not amortized, but is instead tested for impairment at least annually and whenever events or circumstances indicate that it is more likelythan not that it may be impaired. We have elected to perform the annual test of goodwill impairment as of October 31 of each year.In performing tests for goodwill impairment, we are first permitted to perform a qualitative assessment about the likelihood of the carrying value of areporting unit exceeding its fair value. If we determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amountbased on the qualitative assessment, we are required to perform the two-step goodwill impairment test described below to identify the potential goodwillimpairment and measure the amount of the goodwill impairment loss, if any, to be recognized for that reporting unit. However, if we conclude otherwisebased on the qualitative assessment, the two-step goodwill impairment test is not required. The option to perform the qualitative assessment is not anaccounting policy election and can be utilized at our discretion. Further, the qualitative assessment need not be applied to all reporting units in a givengoodwill impairment test. For an individual reporting unit, if we elect not to perform the qualitative assessment, or if the qualitative assessment indicates thatit is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we must perform the two-step goodwill impairment test forthe reporting unit. If the implied fair value of goodwill is less than the carrying value, then an impairment charge would be recorded.In performing the annual goodwill impairment test, we bypassed the option to perform a qualitative assessment and proceeded directly to performingthe first step of the two-step goodwill impairment test. We completed our required annual impairment test for goodwill in the fourth quarter of 2015, 2014and 2013 and determined that at each of those periods the carrying amount of goodwill was not impaired. In each year, our fair value was substantially inexcess of our carrying value.We calculate the fair value of our reporting units using the income approach, which utilizes discounted forecasted future cash flows and the marketapproach which utilizes fair value multiples of comparable publicly traded companies. The discounted cash flows are based on our most recent long-termfinancial projections and 80 Table of Contentsare discounted using a risk adjusted rate of return, which is determined using estimates of market participant risk-adjusted weighted average costs of capitaland reflects the risks associated with achieving future cash flows. The market approach is calculated using the guideline company method, where we usemarket multiples derived from stock prices of companies engaged in the same or similar lines of business. There is not a quoted market price for our reportingunits or the company as a whole, therefore, a combination of the two methods is utilized to derive the fair value of the business. We evaluate and weigh theresults of these approaches as well as ensure we understand the basis of the results of these two methodologies. We believe the use of these twomethodologies ensures a consistent and supportable method of determining our fair value that is consistent with the objective of measuring fair value. If thefair value were to decline, then we may be required to incur material charges relating to the impairment of those assets.We test intangible and long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value of an asset orgroup of assets may not be recoverable. We measure the recoverability of assets to be held and used by comparing the carrying amount of the asset to futureundiscounted net cash flows expected to be generated by the asset. If those assets are considered to be impaired, the impairment equals the amount by whichthe carrying amount of the assets exceeds the fair value of the assets. Any impairments are recorded as permanent reductions in the carrying amount of theassets. Long-lived assets, other than goodwill and other intangible assets, which are held for sale, are recorded at the lower of the carrying value or the fairmarket value less the estimated cost to sell.As of December 31, 2013, we conducted, using our revised sales forecast, an impairment analysis and concluded that the estimate of futureundiscounted cash flows associated with the Cardiolite trademark intangible did not exceed the carrying amount of the asset totaling $19.2 million andtherefore, the asset has been written down to its fair value. Fair value was calculated by utilizing Level 3 inputs in the relief from royalty method, an income-based approach. As a result of this analysis, we recorded an impairment charge of $15.4 million to adjust the carrying value to its fair value of $3.8 million.This expense was recorded within cost of goods sold in the accompanying consolidated statement of operations in the fourth quarter of 2013.During the third quarter of 2013, we committed to a plan to sell certain of our excess land in the U.S. segment, which had a carrying value of $7.5million. This event qualified for held for sale accounting and the excess land was written down to its fair value, less estimated costs to sell. The fair value wasestimated utilizing Level 3 inputs and using a market approach, based on available data for transactions in the region, discussions with real estate brokers andthe asking price of comparable properties in its principal market. This resulted in a loss of $6.4 million, which is included within operating loss as impairmentof land in the accompanying consolidated statement of comprehensive loss. During the fourth quarter of 2013, we sold the excess land for net proceeds of$1.1 million.During the first quarter of 2013, the strategic shift in how we intend to fund our R&D programs significantly altered the expected future costs andrevenues associated with our agents in development. Fixed assets dedicated to R&D activities, which were impacted by the March 2013 R&D strategic shift,have a carrying value of $4.6 million as of December 31, 2015. We believe these fixed assets will be utilized for either internally funded ongoing R&Dactivities or R&D activities funded by a strategic partner. If we are not successful in finding a strategic partner, and there are no alternative uses for thosefixed assets, they could be subject to impairment in the future.Intangible assets, consisting of patents, trademarks and customer relationships related to our products are amortized in a method equivalent to theestimated utilization of the economic benefit of the asset. Trademarks and patents are amortized on a straight-line basis, and customer relationships areamortized on an accelerated basis. 81 Table of ContentsIncome TaxesThe provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. The provision for incometaxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differencesbetween the financial and tax bases of our assets and liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax rates thatapply to taxable income in effect for the years in which those tax attributes are expected to be recovered or paid, and are adjusted for changes in tax rates andtax laws when changes are enacted.Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The assessment ofwhether or not a valuation allowance is required involves the weighing of both positive and negative evidence concerning both historical and prospectiveinformation with greater weight given to evidence that is objectively verifiable. A history of recent losses is negative evidence that is difficult to overcomewith positive evidence. In evaluating prospective information there are four sources of taxable income: reversals of taxable temporary differences, items thatcan be carried back to prior tax years (such as net operating losses), pre-tax income and tax planning strategies. Any tax planning strategies that areconsidered must be prudent and feasible, and would only be undertaken in order to avoid losing an operating loss carryforward. Adjustments to the deferredtax valuation allowances are made in the period when those assessments are made.We account for uncertain tax positions using a recognition threshold and measurement attribute for the financial statement recognition andmeasurement of a tax position taken or expected to be taken in a tax return. Differences between tax positions taken in a tax return and amounts recognized inthe financial statements are recorded as adjustments to income taxes payable or receivable, or adjustments to deferred taxes, or both. We classify interest andpenalties within the provision for income taxes.We have a tax indemnification agreement with BMS related to certain contingent tax obligations arising prior to the acquisition of the business fromBMS. The tax obligations are recognized in liabilities and the tax indemnification receivable is recognized within other noncurrent assets. The changes inthe tax indemnification asset are recognized within other income, net in the statement of operations, and the changes in the related liabilities are recordedwithin the tax provision. Accordingly, as these reserves change, adjustments are included in the tax provision while the offsetting adjustment is included inother income. Assuming that the receivable from BMS continues to be considered recoverable by us, there is no net effect on earnings related to theseliabilities and no net cash outflows.The calculation of our tax liabilities involves certain estimates, assumptions and the application of complex tax regulations in numerous jurisdictionsworldwide. Any material change in our estimates or assumptions, or the tax regulations, may have a material impact on our results of operations. Item 7A.Quantitative and Qualitative Disclosures About Market RiskQuantitative and Qualitative Disclosures About Market RiskWe are exposed to market risk from changes in interest rates and foreign currency exchange rates. We do not hold or issue financial instruments toreduce these risks or for trading purposes.Interest Rate RiskAs a result of our new Term Facility, we have substantial variable rate debt. Fluctuations in interest rates may affect our business, financial condition,results of operations and cash flows. As of December 31, 2015, we had $363.2 million outstanding under our Term Facility with a variable interest rate thatonly varies to the extent LIBOR exceeds one percent.Furthermore, we are subject to interest rate risk in connection with the Revolving Facility, which is variable rate indebtedness. Interest rate changescould increase the amount of our interest payments and thus negatively 82 Table of Contentsimpact our future earnings and cash flows. As of December 31, 2015, there was an $8.8 million unfunded Standby Letter of Credit and $0.1 million accruedinterest, which reduced availability to $39.3 million on the Revolving Facility. Any increase in the interest rate under the Revolving Facility may have anegative impact on our future earnings to the extent we have outstanding borrowings under the Revolving Facility. The effect of a 100 basis points adversechange in market interest rates, in excess of applicable minimum floors, on our interest expense would be approximately $1.9 million.Historically, we have not used derivative financial instruments or other financial instruments to hedge such economic exposures.Foreign Currency RiskWe face exposure to movements in foreign currency exchange rates whenever we, or any of our subsidiaries, enter into transactions with third partiesthat are denominated in currencies other than ours, or that subsidiary’s, functional currency. Intercompany transactions between entities that use differentfunctional currencies also expose us to foreign currency risk.During years ended December 31, 2015, 2014 and 2013, the net impact of foreign currency changes on transactions was a loss of $1.8 million,$279,000 and $349,000, respectively. Historically, we have not used derivative financial instruments or other financial instruments to hedge these economicexposures.A portion of our earnings is generated by our foreign subsidiaries, whose functional currencies are other than the U.S. Dollar. Our earnings could bematerially impacted by movements in foreign currency exchange rates upon the translation of the earnings of those subsidiaries into the U.S. Dollar. TheCanadian Dollar presents the primary currency risk on our earnings. The cost of goods for our products that are manufactured in the United States and are soldin currencies other than the U.S. Dollar by our foreign subsidiaries are also affected by foreign currency exchange rate movements. Our cost of goods wouldhave increased by $2.0 million if the U.S. Dollar had been stronger by 10% when compared to the actual rates used during 2015.If the U.S. Dollar had been uniformly stronger by 10%, compared to the actual average exchange rates, our revenues would have decreased by $3.8million and our net loss would have increased by $1.1 million for the year ended December 31, 2015. 83 Table of ContentsItem 8.

Description of BusinessOverviewHoldings, a Delaware corporation, is the parent company of LMI, also a Delaware corporation.The Company develops, manufactures and commercializes innovative diagnostic medical imaging agents and products that assist clinicians in thediagnosis and treatment of cardiovascular and other diseases. The Company’s commercial products are used by cardiologists, nuclear physicians,radiologists, internal medicine physicians, technologists and sonographers working in a variety of clinical settings. The Company sells its products toradiopharmacies, hospitals, clinics, group practices, integrated delivery networks, group purchasing organizations and, in certain circumstances, wholesalers.The Company sells its products globally and has operations in the United States, Canada, Puerto Rico and Australia and distribution relationships in Europe,Asia Pacific and Latin America.The Company’s portfolio of 10 commercial products is diversified across a range of imaging modalities. The Company’s imaging agents includecontrast agents and medical radiopharmaceuticals (including technetium generators), including the following: • DEFINITY is the leading ultrasound contrast imaging agent used by cardiologists and sonographers during cardiac ultrasound, orechocardiography, exams based on revenue and usage. DEFINITY is an injectable agent that, in the United States, is indicated for use in patientswith suboptimal echocardiograms to assist in the visualization of the left ventricle, the main pumping chamber of the heart. The use ofDEFINITY in echocardiography allows physicians to significantly improve their assessment of the function of the left ventricle. • TechneLite is a self-contained system, or generator, of technetium (Tc99m), a radioisotope with a six hour half-life, used by radiopharmacies toprepare various nuclear imaging agents. • Xenon Xe 133 Gas, or Xenon, is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also cerebral blood flow. • Cardiolite is an injectable, technetium-labeled imaging agent, also known by its generic name sestamibi, used with Single Photon EmissionComputed Tomography, or SPECT, technology in myocardial perfusion imaging, or MPI, procedures that assess blood flow distribution to theheart. • Neurolite is an injectable, technetium-labeled imaging agent used with SPECT technology to identify the area within the brain where blood flowhas been blocked or reduced due to stroke.In the United States, the Company sells DEFINITY through its sales team that calls on healthcare providers in the echocardiography space, as well asgroup purchasing organizations and integrated delivery networks. The Company’s radiopharmaceutical products are primarily distributed throughcommercial radiopharmacies owned or controlled by third parties. In Puerto Rico and Australia, the Company owns three radiopharmacies and sells 90 Table of Contentsits own radiopharmaceuticals, as well as others, directly to end users. In Canada, Europe, Asia Pacific and Latin America, the Company utilizes distributorrelationships to market, sell and distribute its products.2. Summary of Significant Accounting PoliciesBasis of Consolidation and PresentationThe financial statements have been prepared in United States dollars, in accordance with accounting principles generally accepted in the United Statesof America, or U.S. GAAP. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompanyaccounts and transactions have been eliminated in consolidation.The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the discharge ofliabilities in the normal course of business. The Company incurred a net loss of $14.7 million during the year ended December 31, 2015 and had anaccumulated deficit of $359.2 million at December 31, 2015.On June 25, 2015, in conjunction with its initial public offering, or IPO, the Company effected a corporate reorganization, whereby Lantheus MIIntermediate, Inc. (formerly the direct parent of LMI and the direct subsidiary of Holdings) was merged with and into Holdings, or the Merger.On June 30, 2015, the Company completed an IPO of its common stock at a price to the public of $6.00 per share. The Company’s common stock isnow traded on the NASDAQ under the symbol “LNTH”. The Company issued and sold 12,256,577 shares of common stock in the IPO, including 1,423,243shares that were offered and sold pursuant to the underwriters’ exercise in full of their overallotment option. The IPO resulted in proceeds to the Company ofapproximately $67.2 million, after deducting $6.4 million in underwriting discounts, commissions and related expenses.On June 30, 2015, the Company also entered into a $365.0 million senior secured term loan facility, or the Term Facility. The net proceeds of the TermFacility, together with the net proceeds from the IPO and cash on hand of $10.9 million were used to repay in full the aggregate principal amount of LMI’s$400.0 million 9.750% Senior Notes due 2017, or the Notes, pay related premiums, interest and expenses and pay down the $8.0 million of outstandingborrowings under LMI’s $50.0 million revolving credit facility, or the Revolving Facility.The Company currently relies on Jubilant HollisterStier, or JHS, as its sole source manufacturer of DEFINITY, Neurolite and evacuation vials forTechneLite. The Company has additional ongoing technology transfer activities at JHS for its Cardiolite product supply, which is currently approved formanufacture by a single manufacturer. In addition, the Company has ongoing technology transfer activities at Pharmalucence for the manufacture and supplyof DEFINITY.The Company has historically been dependent on key customers and group purchasing organizations for the majority of the sales of its medicalimaging products. The Company’s ability to maintain and profitably renew those contracts and relationships with those key customers and group purchasingorganizations is an important aspect of the Company’s strategy. The Company’s written supply agreements with Cardinal Health, or Cardinal, relating toTechneLite, Xenon, Neurolite, Cardiolite and certain other products expired in accordance with contract terms on December 31, 2014. Following extendeddiscussions with Cardinal, on November 19, 2015, the Company entered into a new contract for the distribution of TechneLite, Xenon, Neurolite and otherproducts beginning in 2015 through 2017. The agreement specifies pricing levels and requirements to purchase minimum volumes of certain products duringcertain periods. The agreement, which expires on December 31, 2017, may be terminated upon the occurrence of specified events, including a material breachby the other party and certain force majeure events. From January 1, 2015 until the signing of the new agreement on November 19, 2015, the Companycontinued to accept and fulfill product orders from Cardinal on a purchase order basis at supply price. 91 Table of ContentsUntil the Company successfully becomes dual sourced for its principal products, the Company is vulnerable to future supply shortages. Disruption inthe financial performance of the Company could also occur if it experiences significant adverse changes in customer mix, broad economic downturns,adverse industry or Company conditions or catastrophic external events. If the Company experiences one or more of these events in the future, it may berequired to implement additional expense reductions, such as a delay or elimination of discretionary spending in all functional areas, as well as scaling backselect operating and strategic initiatives.During 2013 and 2014, the Company utilized its Revolving Facility as a source of liquidity from time to time. Borrowing capacity under theRevolving Facility is calculated by reference to a borrowing base consisting of a percentage of certain eligible accounts receivable, inventory and machineryand equipment minus any reserves, or the Borrowing Base. If the Company is not successful in achieving its forecasted operating results, the Company’saccounts receivable and inventory could be negatively affected, thus reducing the Borrowing Base and limiting the Company’s borrowing capacity. As ofDecember 31, 2015, the aggregate Borrowing Base was approximately $48.2 million, which was reduced by the $8.8 million unfunded Standby Letter ofCredit and$0.1 million in accrued interest, resulting in a net Borrowing Base availability of approximately $39.3 million. The Company’s new Term Facility contains anumber of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds. Incrementalborrowings under the Revolving Facility may affect the Company’s ability to comply with the covenants in the Term Facility, including the financialcovenant restricting total net leverage. Accordingly, the Company may be limited in utilizing its net Borrowing Base availability as a source of liquidity.Based on the Company’s current operating plans, the Company believes its existing cash and cash equivalents, results of operations and availabilityunder the Revolving Facility will be sufficient to continue to fund the Company’s liquidity requirements for at least the next twelve months.Use of EstimatesThe preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptionsthat affect the reported amounts of assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues andexpenses during the reporting period. The more significant estimates reflected in the Company’s consolidated financial statements include certain judgmentsregarding revenue recognition, goodwill, tangible and intangible asset valuation, inventory valuation, asset retirement obligations, income tax liabilities andrelated indemnification receivable, deferred tax assets and liabilities and accrued expenses. Actual results could materially differ from those estimates orassumptions.Stock SplitIn conjunction with the Merger, the Company effected a 0.355872-for-1 reverse stock split for its common stock. Upon consummation of the Merger,the par value of the common stock changed from $0.001 to $0.01. Accordingly, all references to share and per share information in the consolidated financialstatements have been adjusted to reflect the stock split and new par value for all periods presented.Revenue RecognitionThe Company recognizes revenue when evidence of an arrangement exists, title has passed, the risks and rewards of ownership have transferred to thecustomer, the selling price is fixed and determinable, and collectability is reasonably assured. For transactions for which revenue recognition criteria have notyet been met, the respective amounts are recorded as deferred revenue until such point in time the criteria are met and revenue can be recognized. Revenue isrecognized net of reserves, which consist of allowances for returns and rebates. 92 Table of ContentsRevenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the deliveredelement has stand-alone value to the customer. The arrangement’s consideration is then allocated to each separate unit of accounting based on the relativeselling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i) vendor-specificobjective evidence of fair value; (ii) third-party evidence of selling price; and (iii) best estimate of selling price. The best estimate of selling price reflects theCompany’s best estimate of what the selling price would be if the deliverable was regularly sold by the Company on a stand-alone basis. The considerationallocated to each unit of accounting is then recognized as the related goods or services are delivered, limited to the consideration that is not contingent uponfuture deliverables. Supply or service transactions may involve the charge of a nonrefundable initial fee with subsequent periodic payments for futureproducts or services. The up-front fees, even if nonrefundable, are recognized as revenue as the products and/or services are delivered and performed over theterm of the arrangement.Product ReturnsThe Company provides a reserve for its estimate of sales recorded for which the related products are expected to be returned. The Company does nottypically accept product returns unless an over shipment or non-conforming shipment was provided to the customer, or if the product was defective. TheCompany adjusts its estimate of product returns if it becomes aware of other factors that it believes could significantly impact its expected returns, includingproduct recalls. These factors include its estimate of actual and historical return rates for non-conforming product and open return requests. Historically, theCompany’s estimates of returns have reasonably approximated actual returns.Distributor RelationshipsRevenue for product sold to distributors is recognized at shipment, unless revenue recognition criteria have not been met. In those instances wherecollectability cannot be determined or the selling price cannot be reasonably estimated until the distributor has sold through the goods, the Company defersthat revenue until such time as the goods have been sold through to the end-user customer, or the selling price can be reasonably estimated based on historyof transactions with that distributor.Rebates and AllowancesEstimates for rebates and allowances represent the Company’s estimated obligations under contractual arrangements with third parties. Rebate accrualsand allowances are recorded in the same period the related revenue is recognized, resulting in a reduction to revenue and the establishment of a liabilitywhich is included in accrued expenses in the accompanying consolidated balance sheets. These rebates result from performance-based offers that areprimarily based on attaining contractually specified sales volumes and growth, Medicaid rebate programs for certain products, administration fees of grouppurchasing organizations and certain distributor related commissions. The calculation of the accrual for these rebates and allowances is based on an estimateof the third party’s buying patterns and the resulting applicable contractual rebate or commission rate(s) to be earned over a contractual period.The accrual for rebates and allowances was approximately $2.3 million and $2.2 million at December 31, 2015 and 2014, respectively. Rebate andallowance charges against gross revenues totaled $5.9 million, $5.2 million and $4.8 million for the years ended December 31, 2015, 2014 and 2013,respectively.Income TaxesThe Company accounts for income taxes using an asset and liability approach. The provision for income taxes represents income taxes paid or payablefor the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of theCompany’s assets and 93 Table of Contentsliabilities. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in whichthose tax attributes are expected to be recovered or paid, and are adjusted for changes in tax rates and tax laws when changes are enacted.Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. The assessment ofwhether or not a valuation allowance is required involves the weighing of both positive and negative evidence concerning both historical and prospectiveinformation with greater weight given to evidence that is objectively verifiable. A history of recent losses is negative evidence that is difficult to overcomewith positive evidence. In evaluating prospective information there are four sources of taxable income: reversals of taxable temporary differences, items thatcan be carried back to prior tax years (such as net operating losses), pre-tax income, and tax planning strategies. Any tax planning strategies that areconsidered must be prudent and feasible, and would only be undertaken in order to avoid losing an operating loss carryforward. Adjustments to the deferredtax valuation allowances are made in the period when those assessments are made.The Company accounts for uncertain tax positions using a recognition threshold and measurement attribute for the financial statement recognition andmeasurement of a tax position taken or expected to be taken in a tax return. Differences between tax positions taken in a tax return and amounts recognized inthe financial statements are recorded as adjustments to other long-term assets and liabilities, or adjustments to deferred taxes, or both. The Company classifiesinterest and penalties within the provision for income taxes.Loss per ShareBasic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during theperiod. Diluted earnings per common share is computed by dividing net income by the weighted average number of shares of common stock outstandingduring the period, plus the potential dilutive effect of other securities if those securities were converted or exercise. During periods in which the Companyincurs net losses, both basic and diluted loss per share is calculated by dividing the net loss by the weighted average shares outstanding and potentiallydilutive securities are excluded from the calculation because their effect would be anti-dilutive.Cash and Cash EquivalentsCash and cash equivalents include savings deposits, certificates of deposit and money market funds that have original maturities of three months orless when purchased.Accounts ReceivableAccounts receivable consist of amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts forestimated losses. In determining the allowance, consideration includes the probability of recoverability based on past experience and general economicfactors. Certain accounts receivable may be fully reserved when specific collection issues are known to exist, such as pending bankruptcy. As ofDecember 31, 2015 and 2014, the Company had allowances for doubtful accounts of approximately $0.9 million and $0.6 million, respectively.Also included in accounts receivable are miscellaneous receivables of approximately $1.0 million and $2.0 million as of December 31, 2015 and 2014,respectively. 94 Table of ContentsConcentration of Risks and Limited SuppliersFinancial instruments which potentially subject the Company to concentrations of credit risk consist principally of trade accounts receivable. TheCompany periodically reviews its accounts receivable for collectability and provides for an allowance for doubtful accounts to the extent that amounts arenot expected to be collected. The Company sells primarily to large national distributors, which in turn, may resell the Company’s products. There were threecustomers that represented greater than 10% of the total net accounts receivable balance at either December 31, 2015 or 2014. The same three customerscontributed revenues of 12%, 11% and 10% during the year ended December 31, 2015, which is included in the U.S. segment. No other customerscontributed more than 10% of revenue in any of the years ended December 31, 2015, 2014 and 2013.

The failure of one of these suppliers to deliver on schedule could delay or interrupt the manufacturing or commercialization process and therebyadversely affect the Company’s operating results. In addition, a disruption in the commercial supply of, or a significant increase in the cost of one of theCompany’s materials from these sources could have a material adverse effect on the Company’s business, financial position and results of operations. TheCompany has agreements with Nordion and NTP/ANSTO, the Company’s Moly suppliers, with an expiration dates of October 31, 2016 and December 31,2017, respectively. In addition, because Xenon is a by-product of the Moly production process and is currently captured only by Nordion, the Company iscurrently reliant on Nordion as the sole supplier of Xenon to meet customer demand. In March 2013, the Company entered into an agreement with Institutefor Radioelements, or IRE, who had previously been supplying the Company with Moly under the previous agreement with NTP, and this agreement expireson December 31, 2017. In January 2015, the Company announced entering into a new strategic agreement with IRE for the future supply of Xenon. Under theterms of the agreement, IRE will provide bulk Xenon to us for processing and finishing once development work has been completed and all necessaryregulatory approvals have been obtained.The Company currently relies on JHS as its sole source manufacturer of DEFINITY, Neurolite and evacuation vials. The Company has additionalongoing technology transfer activities at JHS for its Cardiolite product supply. In the meantime, the Company has no other currently active supplier ofDEFINITY, Neurolite, and its Cardiolite product supply is approved for manufacture by a single manufacturer.Based on current projections, the Company believes that it will have sufficient supply of DEFINITY, Neurolite and evacuation vials from JHS to meetexpected demand and sufficient Cardiolite product supply and saline from the Company’s current suppliers to meet expected demand.The Company is working to secure additional alternative suppliers for its key products as part of its ongoing supply chain diversification strategy. OnNovember 12, 2013, the Company entered into a Manufacturing and Supply Agreement with Pharmalucence to manufacture and supply DEFINITY.However, the Company is uncertain on the timing in which the Pharmalucence arrangement or any other arrangements could provide meaningful quantitiesof product. 95 Table of ContentsThe following table sets forth revenues for the Company’s products that represented greater than 10% of total revenue for the years endedDecember 31, 2015, 2014 and 2013. Year EndedDecember 31, 2015 2014 2013 DEFINITY 38.1% 31.8% 27.5% TechneLite 24.7% 31.0% 32.5% Xenon 16.7% 12.1% 11.3% InventoryInventory includes material, direct labor and related manufacturing overhead, and is stated at the lower of cost or market on a first-in, first-out basis.The Company does have consignment arrangements with certain customers where the Company retains title and the risk of ownership of the inventory, whichis included in the Company’s inventory balance.The Company assesses the recoverability of inventory to determine whether adjustments for excess and obsolete inventory are required. Inventory thatis in excess of future requirements is written down to its estimated net realizable value based upon forecasted demand for its products. If actual demand is lessfavorable than what has been forecasted by management, additional inventory write-downs may be required.Inventory costs associated with product that has not yet received regulatory approval are capitalized if the Company believes there is probable futurecommercial use of the product and future economic benefits of the asset. If future commercial use of the product is not probable, then inventory costsassociated with such product are expensed during the period the costs are incurred. For the year ended December 31, 2015, the Company expensed $0.6million of such product costs in cost of goods sold relating to Cardiolite that was manufactured by JHS. For the year ended December 31, 2014, the Companyexpensed $1.9 million of such product costs in cost of goods sold relating to Neurolite that was manufactured by JHS. At December 31, 2015 and 2014, theCompany had no capitalized inventories associated with product that did not have regulatory approval.Property, Plant and EquipmentProperty, plant and equipment are stated at cost. Replacements of major units of property are capitalized, and replaced properties are retired.Replacements of minor components of property and repair and maintenance costs are charged to expense as incurred. Depreciation is computed on a straight-line method based on the estimated useful lives of the related assets. The estimated useful lives of the major classes of depreciable assets are as follows: Buildings 50 yearsLand improvements 15 - 40 yearsMachinery and equipment 3 - 20 yearsFurniture and fixtures 15 yearsLeasehold improvements Lesser of lease term or 15 yearsUpon retirement or other disposal of property, plant and equipment, the cost and related amount of accumulated depreciation are removed from theasset and accumulated depreciation accounts, respectively. The difference, if any, between the net asset value and the proceeds is included in operations.Capitalized Software Development CostsCertain costs to obtain internal use software for significant systems projects are capitalized and amortized over the estimated useful life of the software,which ranges from 3 to 5 years. Costs to obtain software for 96 Table of Contentsprojects that are not significant are expensed as incurred. Capitalized software development costs, net of accumulated amortization, were $9.1 million and$2.4 million at December 31, 2015 and 2014, respectively. Amortization expense related to the capitalized software was $1.1 million, $0.7 million and $1.5million for the years ended December 31, 2015, 2014 and 2013, respectively. Future amortization expense for all capitalized software placed in service as ofDecember 31, 2015 is estimated to be $2.2 million, $2.0 million, $2.0 million, $1.7 million and $1.2 million for the years ending December 31, 2016, 2017,2018, 2019 and 2020, respectively.Goodwill, Intangibles and Long-Lived AssetsGoodwill is not amortized, but is instead tested for impairment at least annually and whenever events or circumstances indicate that it is more likelythan not that they may be impaired. The Company has elected to perform the annual test for goodwill impairment as of October 31 of each year.In performing tests for goodwill impairment, the Company is first permitted to perform a qualitative assessment about the likelihood of the carryingvalue of a reporting unit exceeding its fair value. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than itscarrying amount based on the qualitative assessment, it is required to perform the two-step goodwill impairment test described below to identify the potentialgoodwill impairment and measure the amount of the goodwill impairment loss, if any, to be recognized for that reporting unit. However, if the Companyconcludes otherwise based on the qualitative assessment, the two-step goodwill impairment test is not required. The option to perform the qualitativeassessment is not an accounting policy election and can be utilized at the Company’s discretion. Further, the qualitative assessment need not be applied toall reporting units in a given goodwill impairment test. For an individual reporting unit, if the Company elects not to perform the qualitative assessment, or ifthe qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Companymust perform the two-step goodwill impairment test for the reporting unit. If the implied fair value of goodwill is less than the carrying value, then animpairment charge would be recorded.In performing the annual goodwill impairment test in 2015 and 2014, the Company bypassed the option to perform a qualitative assessment andproceeded directly to performing the first step of the two-step goodwill impairment test.The Company calculates the fair value of its reporting units using the income approach, which utilizes discounted forecasted future cash flows, and themarket approach which utilizes fair value multiples of comparable publicly traded companies. The discounted cash flows are based on our most recent long-term financial projections and are discounted using a risk adjusted rate of return, which is determined using estimates of market participant risk-adjustedweighted average costs of capital and reflects the risks associated with achieving future cash flows. The market approach is calculated using the guidelinecompany method, where the Company uses market multiples derived from stock prices of companies engaged in the same or similar lines of business. There isnot a quoted market price for the Company’s reporting units or the company as a whole, therefore, a combination of the two methods is utilized to derive thefair value of the business. The Company evaluated and weighed the results of these approaches as well as ensures it understands the basis of the results ofthese two methodologies. The Company believes the use of these two methodologies ensures a consistent and supportable method of determining its fairvalue that is consistent with the objective of measuring fair value. If the fair value were to decline, then the Company may be required to incur materialcharges relating to the impairment of those assets. The Company completed its required annual impairment test for goodwill in the fourth quarter of 2015,2014 and 2013 and determined that at each of those periods, the Company’s fair value was substantially in excess of its carrying value.The Company tests intangible and long-lived assets for recoverability whenever events or changes in circumstances suggest that the carrying value ofan asset or group of assets may not be recoverable. The Company measures the recoverability of assets to be held and used by comparing the carrying amountof the asset to future undiscounted net cash flows expected to be generated by the asset. If those assets are considered to 97 Table of Contentsbe impaired, the impairment equals the amount by which the carrying amount of the assets exceeds the fair value of the assets. Any impairments are recordedas permanent reductions in the carrying amount of the assets. Long-lived assets, other than goodwill and other intangible assets, that are held for sale arerecorded at the lower of the carrying value or the fair market value less the estimated cost to sell.As of December 31, 2013, the Company conducted, using its revised sales forecast, an impairment analysis and concluded that the estimate of futureundiscounted cash flows associated with the Cardiolite trademark intangible did not exceed the carrying amount of the asset totaling $19.2 million andtherefore, the asset was written down to its fair value. Fair value was calculated by utilizing Level 3 inputs in the relief-from-royalty method, an income-basedapproach. As a result of this analysis, the Company recorded an impairment charge of $15.4 million to adjust the carrying value to its fair value of $3.8million. This expense was recorded within cost of goods sold in the accompanying consolidated statement of operations in the fourth quarter of 2013.In the third quarter of 2013, the Company was in negotiations with a new distributor for the sale of certain products within certain internationalmarkets. This agreement was signed in October 2013 and as a result the Company did not renew the agreements with its former distributors in theseinternational markets. The Company determined the customer relationship intangible related to these former distributors was no longer recoverable andrecorded an impairment charge of $1.0 million in the third quarter of 2013. In the fourth quarter of 2013, the Company updated its strategic plan to reflect thenon-renewal of these agreements and the uncertainty in the timing of product availability in this region. As a result, the Company reviewed the recoverabilityof certain of its customer relationship intangible assets in the International segment that were impacted by the Company’s revised strategic plan. TheCompany conducted an impairment analysis and concluded that the estimate of future undiscounted cash flows associated with the customer relationshipintangible asset did not exceed the carrying amount of the asset and therefore, the asset would need to be written down to its fair value. In order to calculatethe fair value of the acquired customer relationship intangible assets, the Company utilized Level 3 inputs to estimate the future discounted cash flowsassociated with remaining customers and as a result of this analysis, recorded an impairment charge of $0.7 million in the fourth quarter of 2013. Theseimpairment charges were recorded within cost of goods sold in the accompanying consolidated statement of operations.During the third quarter of 2013, the Company committed to a plan to sell certain of its excess land in the U.S. segment, which had a carrying value of$7.5 million. This event qualified for held for sale accounting and the excess land was written down to its fair value, less estimated costs to sell. The fair valuewas estimated utilizing Level 3 inputs and using a market approach, based on available data for transactions in the region, discussions with real estate brokersand the asking price of comparable properties in its principal market. This resulted in a loss of $6.4 million, which is included within operating loss asimpairment of land in the accompanying consolidated statement of operations. During the fourth quarter of 2013, the Company sold the excess land for netproceeds of $1.1 million.During the first quarter of 2013, the strategic shift in how the Company funds its R&D programs significantly altered the expected future costs andrevenues associated with our agents in development. Fixed assets dedicated to R&D activities, which were impacted by the March 2013 R&D strategic shift,have a carrying value of $4.6 million as of December 31, 2015. The Company believes these fixed assets will be utilized for either internally funded ongoingR&D activities or R&D activities funded by a strategic partner. If the Company is not successful in finding a strategic partner, and there are no alternativeuses for those fixed assets, they could be subject to impairment in the future.Intangible assets, consisting of patents, trademarks and customer relationships related to the Company’s products are amortized in a method equivalentto the estimated utilization of the economic benefit of the asset. Trademarks and patents are amortized on a straight-line basis, and customer relationships areamortized on an accelerated basis. 98 Table of ContentsDeferred Financing CostsDuring 2015, the Company early adopted ASU No. 2015-03, Interest—Imputation of Interest (Topic 835): Simplifying the Presentation of DebtIssuance Costs, or ASU 2015-03. Adoption of this standard has resulted in the reclassification of $5.5 million and $6.4 million from other long-term assets tolong-term debt, net on the balance sheet at December 31, 2015 and 2014, respectively. Deferred financing costs related to the Revolving Facility of $1.1million and $0.9 million are presented in other long-term assets at December 31, 2015 and 2014, respectively. Deferred financing costs are amortized tointerest expense using the effective interest rate method. The expense associated with the amortization of deferred financing costs was $1.9 million, $2.5million and $2.4 million for the years ended December 31, 2015, 2014 and 2013, respectively. In connection with the redemption of the Notes, the Companywrote off $5.8 million of existing unamortized debt issuance costs, which is included in loss on extinguishment of debt in the accompanying consolidatedstatements of operations during the year ended December 31, 2015. During the year ended December 31, 2013, the Company wrote off $0.6 million of theexisting unamortized deferred financing costs related to a previous facility, which is included in interest expense in the accompanying consolidatedstatements of operations.ContingenciesIn the normal course of business, the Company is subject to loss contingencies, such as legal proceedings and claims arising out of its business, thatcover a wide range of matters, including, among others, product and environmental liability. The Company records accruals for those loss contingencieswhen it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company does not recognize gain contingenciesuntil realized.Fair Value of Financial InstrumentsThe estimated fair values of the Company’s financial instruments, including its cash and cash equivalents, receivables, accounts payable and accruedexpenses approximate the carrying values of these instruments due to their short term nature. Assets measured at fair value on a nonrecurring basis includelong-lived assets held for sale and certain intangible assets. The estimated fair value of the Company’s Term Facility at December 31, 2015, approximatescarrying value because the interest rate is subject to change with market interest rates. The estimated fair value of the debt, at December 31, 2014, based onLevel 2 inputs of recent market activity available to the Company was $384.0 million compared to the face value of $400.0 million.Shipping and Handling Revenues and CostsThe Company typically does not charge customers for shipping and handling costs, but any shipping and handling costs charged to customers areincluded in revenues. Shipping and handling costs are included in cost of goods sold and were $17.4 million, $19.4 million and $20.5 million for the yearsended December 31, 2015, 2014 and 2013, respectively.Advertising and Promotion CostsAdvertising and promotion costs are expensed as incurred and totaled $3.1 million, $2.8 million and $2.7 million for the years ended December 31,2015, 2014 and 2013, respectively, and are included in sales and marketing expenses.Research and DevelopmentResearch and development costs are expensed as incurred and relate primarily to the development of new products to add to the Company’s portfolioand costs related to its medical affairs and medical information functions. Nonrefundable advance payments for goods or services that will be used orrendered for future research and development activities are deferred and recognized as an expense as the goods are delivered or the related services areperformed. 99 Table of ContentsForeign CurrencyThe consolidated statements of operations of the Company’s foreign subsidiaries are translated into U.S. Dollars using average exchange rates. The netassets of the Company’s foreign subsidiaries are translated into U.S. Dollars using the end of period exchange rates. The impact from translating the net assetsof these subsidiaries at changing rates are recorded in the foreign currency translation adjustment account, which is included in accumulated othercomprehensive loss.For the years ended December 31, 2015, 2014 and 2013, losses arising from foreign currency transactions totaled approximately $1.8 million, $0.3million and $0.3 million, respectively. Transaction gains and losses are reported as a component of other income (expense), net.Stock-Based CompensationThe Company’s stock-based compensation cost is measured at the grant date of the stock-based award based on the fair value of the award and isrecognized as expense over the requisite service period, which generally represents the vesting period, and includes an estimate of the awards that will beforfeited. The Company uses the Black-Scholes valuation model for estimating the fair value of stock options. The fair value of stock option awards isaffected by the valuation assumptions, including the estimated fair value of the Company’s common stock, the expected volatility based on comparablemarket participants, expected term of the option, risk-free interest rate and expected dividends. When a contingent cash settlement of vested options becomesprobable, the Company reclassifies its vested awards to a liability and accounts for any incremental compensation cost in the period in which the settlementbecomes probable.Accumulated Other Comprehensive LossComprehensive loss is comprised of net loss, plus all changes in equity of a business enterprise during a period from transactions and other events andcircumstances from non-owner sources, including any foreign currency translation adjustments. These changes in equity are recorded as adjustments toaccumulated other comprehensive loss in the Company’s consolidated balance sheet. The components of accumulated other comprehensive loss consist offoreign currency translation adjustments.Asset Retirement ObligationsThe Company’s compliance with federal, state, local and foreign environmental laws and regulations may require it to remove or mitigate the effects ofthe disposal or release of chemical substances in jurisdictions where it does business or maintains properties. The Company establishes accruals when thosecosts are legally obligated and probable and can be reasonably estimated. Accrual amounts are estimated based on currently available information, regulatoryrequirements, remediation strategies, historical experience, the relative shares of the total remediation costs and a relevant discount rate, when the timeperiods of estimated costs can be reasonably predicted. Changes in these assumptions could impact the Company’s future reported results. The amountsrecorded for asset retirement obligations in the accompanying balance sheets at December 31, 2015 and 2014 were $8.1 million and $7.4 million,respectively.Self Insurance ReservesThe Company’s consolidated balance sheet at both December 31, 2015 and 2014 includes approximately $0.4 million of accrued liabilities associatedwith employee medical costs that are retained by the Company. The Company estimates the required liability of those claims on an undiscounted basis basedupon various assumptions which include, but are not limited to, the Company’s historical loss experience and projected loss development factors. Therequired liability is also subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents(frequency) and change in the ultimate cost per 100 Table of Contentsincident (severity). The Company also maintains a separate cash account to fund these medical claims and must maintain a minimum balance as determinedby the plan administrator. The balance of this restricted cash account was approximately $0.1 million at both December 31, 2015 and 2014, and is includedin other current assets.Recent Accounting StandardsIn May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) or ASU 2014-09. ASU 2014-09 supersedes nearlyall existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or servicesare transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 defines afive step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognitionprocess than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variableconsideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In August 2015, the FASBissued ASU 2015-14, Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date, which defers the effective date of ASU 2014-09 toannual reporting periods beginning after December 15, 2017 with early adoption permitted as of its original effective date of December 15, 2016. The newguidance requires either a retrospective or a modified retrospective approach to adoption. The Company is currently evaluating the impact this ASU willhave on our financial position, results of operations, cash flows, and disclosures.In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-4): Disclosure of Uncertaintiesabout an Entity’s Ability to Continue as a Going Concern or ASU 2014-15. ASU 2014-15 to provide guidance on management’s responsibility in evaluatingwhether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments inASU 2014-15 are effective for annual reporting periods ending after December 15, 2016. Early adoption is permitted. The Company does not anticipate thisASU will have a material impact to the Company’s financial position, results of operations or cash flows.3. Financial Instruments and Fair Value MeasurementsFair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between marketparticipants at the measurement date. In order to increase consistency and comparability in fair value measurements, financial instruments are categorizedbased on a hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access atthe measurement date.Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets orliabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.)and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).Level 3 — Unobservable inputs that reflect a Company’s estimates about the assumptions that market participants would use in pricing the assetor liability. The Company develops these inputs based on the best information available, including its own data.At December 31, 2015 and 2014, the Company’s financial assets that are measured at fair value on a recurring basis are comprised of moneymarket securities and are classified as cash equivalents. The Company invests excess cash from its operating cash accounts in overnight investmentsand reflects these amounts in cash and cash equivalents on the consolidated balance sheet using quoted prices in active markets for identical assets(Level 1). 101 Table of ContentsThe tables below present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of December 31,2015 and 2014: (in thousands) Total fairvalue atDecember 31,2015 Quotedprices inactivemarkets(Level 1) Significantotherobservableinputs(Level 2) Significantunobservableinputs(Level 3) Money market $1,586 $1,586 $— $— Certificates of deposit—restricted 74 — 74 — $1,660 $1,586 $74 $— (in thousands) Total fairvalue atDecember 31,2014 Quotedprices inactivemarkets(Level 1) Significantotherobservableinputs(Level 2) Significantunobservableinputs(Level 3) Money market $2,737 $2,737 $— $— Certificates of deposit—restricted 89 — 89 — $2,826 $2,737 $89 $— At both December 31, 2015 and December 31, 2014, the Company has a $0.1 million certificate of deposit which is collateral for a long-term lease andis included in other long-term assets on the consolidated balance sheet.

These amounts are primarily associated with domestic state tax issues, such as the allocation of incomeamong various state tax jurisdictions and transfer pricing. Since the Company operates in a number of countries in which it has income tax treaties, it believesthat it is more-likely-than-not that the Company should be able to receive competent authority relief for potential adjustments in those countries. Included inthe Company’s uncertain tax positions for transfer pricing exposures are $0.6 million, which is reflected within other long-term liabilities, and an offset of$0.2 million for expected competent authority relief, which is reflected in other long-term assets. The tabular rollforward reflected above is net of the $0.2million of competent authority relief as of December 31, 2015.As of December 31, 2015 and 2014, total liabilities for tax obligations and associated interest and penalties were $33.8 million and $33.2 million,respectively, consisting of income tax provisions for uncertain tax benefits of $11.7 million and $12.4 million, interest accruals of $19.9 million and $18.6million, respectively, and penalty accruals of $2.2 million, which were included in other long-term liabilities on the consolidated balance sheets. Included inthe 2015, 2014 and 2013 tax provision is $2.5 million, $1.2 million and $1.9 million, respectively, relating to interest and penalties, net of benefits forreversals of uncertain tax position interest and penalties recognized upon settlements and lapse of statute of limitations.In accordance with the Company’s acquisition of the medical imaging business from Bristol Myers Squibb (“BMS”) in 2008, the Company obtained atax indemnification agreement with BMS related to certain tax obligations arising prior to the acquisition of the Company, for which the Company has theprimary legal 104 Table of Contentsobligation. The tax indemnification receivable is recognized within other noncurrent assets. The total noncurrent asset related to the indemnification was$17.6 million and $17.8 million at December 31, 2015 and 2014, respectively. The changes in the tax indemnification asset are recognized within otherincome (expense), net in the consolidated statement of operations. In accordance with the Company’s accounting policy, the change in the tax liability andpenalties and interest associated with these obligations (net of any offsetting federal or state benefit) is recognized within the tax provision. Accordingly, asthese reserves change, adjustments are included in the tax provision while the offsetting adjustment is included in other income (expense), net. Assuming thatthe receivable from BMS continues to be considered recoverable by the Company, there is no net effect on earnings related to these liabilities and no net cashoutflows.During the year ended December 31, 2015 and 2014, BMS, on behalf of the Company, made payments totaling $1.9 million and $6.3 million,respectively to a number of states in connection with prior year state income tax filings. The amount due from BMS, included within other long-term assets,decreased by $1.6 million and $2.9 million for the year ended December 31, 2015 and 2014, respectively, which represented the release of asset balancesassociated with pre-acquisition years. There were no payments made on behalf of the Company in 2013.Included in other income (expense), net for the years ended December 31, 2015 and 2014, is an expense of $0.4 million and $1.1 million, respectively,relating to the reduction in the indemnification receivable from BMS associated with the expiration of statute of limitations and income of $2.1 million and$1.9 million at December 31, 2015 and 2014, respectively, relating to the increase in the indemnification receivable for current year interest and penalties.The Company has generated domestic pre-tax losses in two of the past three years. This loss history demonstrates negative evidence concerning theCompany’s ability to utilize its domestic gross deferred tax assets. In order to overcome the presumption of recording a valuation allowance against thedeferred tax assets, the Company must have sufficient positive evidence that it can generate sufficient taxable income to utilize these deferred tax assetswithin the carryover or forecast period. Although the Company has no history of expiring net operating losses or other tax attributes, based on the cumulativedomestic loss incurred over the three-year period ended December 31, 2015, management determined that the net U.S. deferred tax assets are not more-likely-than-not recoverable. As a result of this analysis, the Company continues to maintain a full valuation allowance primarily against its net U.S. deferred taxassets in the amount of $154.3 million and $152.1 million at December 31, 2015 and 2014, respectively.The following is a reconciliation of the Company’s valuation allowance for the years ended December 31, 2015, 2014, and 2013.

The state income tax returns remain subject to examination forthree to four years depending on the state’s statute of limitations.At December 31, 2015, the Company has federal net operating loss carryovers of $175.5 million, which will begin to expire in 2031 and completelyexpire in 2034. The Company has $2.4 million of federal research credits, which begin to expire in 2029. The Company has foreign tax credits ofapproximately $4.4 million that will begin to expire in 2020. The Company has state research credits of $1.8 million, which will expire between 2024 and2029. The Company has Massachusetts investment tax credits of approximately $0.3 million, which have no expiration date.In 2010, the Company was granted a tax holiday from the Commonwealth of Puerto Rico, which expires on January 1, 2024. This grant provides for a4% tax rate on activities relating to the operations of the Company’s radiopharmacies. This grant is conditioned upon the Company meeting certainemployment and investment thresholds. The impact of this tax holiday was immaterial in 2015.5. Assets Held for SaleDuring the fourth quarter of 2015, the Company committed to a plan to sell certain assets and liabilities associated with the Company’s internationalbusiness. This event qualified for held for sale accounting and the Company has determined that the fair value of the net assets being sold significantlyexceeds the carrying value as of December 31, 2015. The transaction was finalized in the first quarter of 2016.Effective January 7, 2016, the Canadian subsidiary of the Company, entered into an asset purchase agreement, the Purchase Agreement, pursuant towhich it would sell substantially all of the assets of its Canadian radiopharmacies and Gludef manufacturing and distribution business to one of its existingCanadian radiopharmacy customers.The purchase price for the asset sale was $9.0 million in cash, which is subject to certain working capital adjustment calculations. The PurchaseAgreement contained customary representations, warranties and covenants by each of the parties. Subject to certain limitations, the buyer will be indemnifiedfor damages resulting from breaches or inaccuracies of the Company’s representations, warranties and covenants in the Purchase Agreement.As part of the transaction, the Company and the buyer also entered into a customary transition services agreement and a long-term supply contractunder which the Company will supply the buyer with the Company’s products on commercial terms and under which the buyer has agreed to certain productpurchase commitments.The Company does not believe the sale of certain net assets in the international business constitute a strategic shift that would have a major effect onits operations or financial results. As a result, this transaction has not been classified as discontinued operations in the Company’s financial statements andhas been classified as assets and liabilities held for sale as of December 31, 2015. 106 Table of ContentsThe following table summarizes the major classes of assets and liabilities classified as held for sale as of December 31, 2015.

Asset Retirement ObligationsThe Company considers the legal obligation to remediate its facilities upon a decommissioning of its radioactive related operations as an assetretirement obligation. The operations of the Company have radioactive production facilities at its North Billerica, Massachusetts and San Juan, Puerto Ricosites.The Company is required to provide the U.S. Nuclear Regulatory Commission and Massachusetts Department of Public Health financial assurancedemonstrating the Company’s ability to fund the decommissioning of the North Billerica, Massachusetts production facility upon closure, although theCompany does not intend to close the facility. The Company has provided this financial assurance in the form of a $28.2 million surety bond, which itself iscurrently secured by an $8.8 million unfunded Standby Letter of Credit provided to the third party issuer of the bond.The fair value of a liability for asset retirement obligations is recognized in the period in which the liability is incurred. As of December 31, 2015, theliability is measured at the present value of the obligation expected to be incurred, of approximately $26.6 million, and is adjusted in subsequent periods asaccretion expense is recorded. The corresponding asset retirement costs are capitalized as part of the carrying value of the related long-lived assets anddepreciated over the asset’s useful life.The following is a reconciliation of the Company’s asset retirement obligations for the years ended December 31, 2015, 2014 and 2013: (in thousands) Balance at January 1, 2013 $5,416 Net increase due to changes in estimated future cash flows 341 Accretion expense 628 Balance at December 31, 2013 6,385 Capitalization 277 Accretion expense 773 Balance at December 31, 2014 7,435 Net decrease due to changes in estimated future cash flows (37) Accretion expense 747 Balance at December 31, 2015 $8,145 108 Table of Contents9.

During a cash dominion period, the Company is required to comply with a consolidated fixed charge coverage ratio of not less than 1: 00:1:00. The fixed charge coverage ratio is calculated on a consolidated basis for Lantheus Holdings and its subsidiaries for a trailing four fiscal quarter periodbasis, as (i) EBITDA (as defined in the agreement) minus capital expenditures minus certain restricted payments divided by (ii) interest plus taxes paid orpayable in cash plus certain restricted payments made in cash plus scheduled principal payments paid or payable in cash. Upon an event of default, the lenderhas the right to declare the loans and other obligations outstanding immediately due and payable and all commitments immediately terminated or reduced,and the lender may, after such events of default, require LMI to make deposits with respect to any outstanding letters of credit in an amount equal to 105% ofthe greatest amount for which such letter of credit may be drawn.Financing CostsOn June 30, 2015, LMI incurred and capitalized approximately $5.9 million in debt issuance costs, consisting primarily of underwriting fees andexpenses and legal fees in connection with the issuance of the Term Facility. 112 Table of ContentsDuring the years ended December 31, 2015 and 2014, LMI incurred approximately $0.4 million and $0.2 million in fees and expenses, in connectionwith amendments under the previous facility, which are being amortized on a straight-line basis over the term of the Revolving Facility.12.

The common stockholders are entitled to one vote per share and will share equally on aper share basis in any dividend declared by the Board of Directors, subject to any preferential rights of the holders of any outstanding preferred stock.13. Stock-Based CompensationAs of June 24, 2015, the Company adopted the 2015 Equity Incentive Plan, or the 2015 Plan.The Company’s employees are eligible to receive awards under the 2015 Plan. The 2015 Plan is administered by the Board of Directors and permits thegranting of stock options, stock appreciation rights, or SARs, restricted stock, restricted stock units and dividend equivalent rights (“DERs”) to employees,officers, directors and consultants of the Company. The Board of Directors may, at its sole discretion, grant DERs with respect to any award and such DER istreated as a separate award. The number of shares authorized for issuance under the 2015 Plan is 2,190,320. Option awards under the 2015 Plan are grantedwith an exercise price equal to the fair value of the Company’s common stock at the date of grant. Time based option awards vest based on time, typicallyfour years, and performance based option awards vest based on the performance criteria specified in the grant. All option awards have a ten-year contractualterm. The Company recognizes compensation costs for its time based awards on a straight-line basis equal to the vesting period. The compensation cost forperformance based awards is recognized on a graded vesting basis, based on the probability of achieving the performance targets over the requisite serviceperiod for the entire award. The fair value of each option award is estimated on the date of grant using a Black-Scholes valuation model that uses theassumptions noted in the following table. Expected volatilities are based on the historic volatility of a selected peer group. Expected dividends represent thedividends expected to be issued at the date of grant. The expected term of options represents the period of time that options granted are expected to beoutstanding. The risk-free interest rate assumption is the U.S. Treasury rate at the date of the grant which most closely resembles the expected life of theoptions.

During the year ended December 31, 2014, 6,237 options were exercised.The intrinsic value for the options exercised during the year ended December 31, 2014 was approximately $25,000.Stock-based compensation expense for both time based and performance based awards was recognized in the consolidated statements of operations asfollows: Years Ended December 31, (in thousands) 2015 2014 2013 Cost of goods sold $192 $135 $41 Sales and marketing 254 154 93 General and administrative 1,330 621 429 Research and development 226 121 15 Total stock-based compensation expense $2,002 $1,031 $578 Stock-based compensation expense recognized in the consolidated statement of operations for the years ended December 31, 2015, 2014, and 2013 arebased on awards ultimately expected to vest as well as any changes in the probability of achieving certain performance features as required. Upon terminationof employment, the Company has the right to call shares held by employees that were purchased or acquired through option exercise. As a result of this right,upon termination of service, vested stock-based awards are reclassified to liability-based awards when it is probable the employee will exercise the optionand the Company will exercise its call right. The Company did not reclassify any equity awards to liability-based awards as of December 31, 2015 and 2014.There were no liability awards paid out during the years ended December 31, 2015, 2014 and 2013. 114 Table of ContentsA summary of restricted stock awards activity for 2015 is presented below: Time Based WeightedAverage GrantDate Fair Value PerShare Issued and unvested at January 1, 2015 — $— Granted 1,368,700 5.97 Vested — — Forfeited (280,532) 6.01 Issued and unvested at December 31, 2015 1,088,168 $5.96 The Company did not recognize an income tax benefit for the years ended December 31, 2015, 2014 and 2013. As of December 31, 2015, there wasapproximately $5.6 million of total unrecognized compensation costs related to stock options and restricted stock awards granted under the 2015, 2013 and2008 Plans. These costs are expected to be recognized over a weighted-average remaining period of 3.1 years. In addition, performance based awards containcertain contingent features, such as change in control provisions, which allow for the vesting of previously forfeited and unvested awards.14. Net Loss Per ShareBasic income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstandingduring the period. Diluted earnings per common share is computed by dividing net income by the weighted average number of shares of common stockoutstanding during the period, plus the potential dilutive effect of other securities if those securities were converted or exercised. During periods in which theCompany incurs net losses, both basic and diluted loss per share is calculated by dividing the net loss by the weighted average shares outstanding andpotentially dilutive securities are excluded from the calculation because their effect would be antidilutive.
