BusinessOverviewWe 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. Clinicians use our imaging agents and products across a range ofimaging modalities, including echocardiography and nuclear imaging. 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 cardiologists, nuclear physicians, radiologists, internal medicinephysicians, sonographers and technologists working in a variety of clinical settings.We sell our products globally and operate our business in two reportable segments, which are further described below: • U.S. Segment produces and markets our medical imaging agents and products throughout the U.S. In the U.S., we primarily sell our products toradiopharmacies, integrated delivery networks, hospitals, clinics and group practices. • International Segment operations consist of production and distribution activities in Puerto Rico and direct distribution activities in Canada.Additionally, within our International Segment, we have established and maintain third-party distribution relationships under which ourproducts are marketed and sold in Europe, Canada, Australia, Asia Pacific and Latin America.During the year ended December 31, 2016, we sold certain business units that were part of our International Segment business. In January 2016, weentered into an asset purchase agreement pursuant to which we sold substantially all of our Canadian radiopharmacy business and Gludef manufacturing anddistribution business. In August 2016, we entered into a share purchase agreement pursuant to which we sold all of the stock of our Australian radiopharmacyservicing subsidiary. See Footnote 5, “Sales of Certain International Segment Assets” included in the consolidated financial statements located elsewhere inthis Annual Report on Form 10-K.For further information on our products and segments, see “—Our Product Portfolio” within this Item 1. “Business.”Our Product PortfolioOur portfolio of nine commercial products is diversified across a range of imaging modalities. Our products include an ultrasound contrast agent andmedical radiopharmaceuticals (including technetium generators). • Ultrasound contrast agents are compounds that are used in diagnostic procedures such as cardiac ultrasounds, or echocardiograms that are usedby physicians to improve the clarity of the diagnostic image. • Medical 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. 4Table of Contents • Radioisotopes are most commonly manufactured in a nuclear research reactor, where a target is bombarded with subatomic particles, or ina 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 (“SPECT”) which measures gammarays emitted by a SPECT radiopharmaceutical, and positron emission tomography (“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 cardiovascular disease, a typical diagnostic progression couldinclude an electrocardiogram, followed by an echocardiogram (possibly using our agent DEFINITY), and then a nuclear myocardial perfusion imaging(“MPI”) study using either SPECT or PET imaging (possibly using our technetium generator and our SPECT-based MPI agent). An MPI study assesses bloodflow distribution to the heart. MPI is also used for diagnosing the presence of coronary artery disease.DEFINITYDEFINITY is the leading ultrasound contrast imaging agent based on revenue and usage in the U.S., and 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 U.S.—over 31.8 million in 2016—a third party source estimates that approximately20%, or approximately 6.4 million echocardiograms in 2016, produce suboptimal images. The use of DEFINITY during echocardiography allows physiciansto significantly improve their assessment of the function of the left ventricle.DEFINITY is a clear, colorless, sterile liquid, which, upon activation in a 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 U.S. and ininternational markets as we continue to grow contrast penetration through sales and marketing efforts focused on the appropriate use of contrast and maintainour leading position.Since its launch in 2001, DEFINITY has been used in imaging procedures in more than 8.1 million patients throughout the world. In 2016, DEFINITYwas the leading ultrasound imaging agent based on revenue and usage, used by echocardiologists and sonographers. We estimate that DEFINITY had anapproximately 80% share of the U.S. market for contrast agents in echocardiography procedures as of December 2016. DEFINITY currently competes withOptison, a GE Healthcare product, Lumason, a Bracco product (known as SonoVue outside the U.S.) as well as other non-echocardiography imagingmodalities. DEFINITY, Optison and Lumason all carry an FDA-required boxed warning, which has been modified over time, to notify physicians and patientsabout potentially serious safety concerns or risks posed by the products. See Part I, Item 1A. “Risk Factors—Ultrasound contrast agents may cause side effectswhich could limit our ability to sell DEFINITY.”DEFINITY is currently patent protected in the U.S. with a composition of matter patent expiring in 2019 and a manufacturing patent expiring in 2021.In addition, DEFINITY is protected in numerous foreign 5Table of Contentsjurisdictions with patent or regulatory protection until 2019. We also have an active next generation development program for this agent. DEFINITYgenerated revenues of $131.6 million, $111.9 million and $95.8 million for the years ended December 31, 2016, 2015 and 2014, respectively. DEFINITYrepresented approximately 44%, 38% and 32% of our revenues in 2016, 2015 and 2014, respectively.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 Moly itself a radioisotope with a 66-hour half-life produced innuclear research reactors around the world from enriched uranium. The TechneLite generator is a little larger than a coffee can in size, and the self-containedsystem houses a vertical glass column at its core that contains Moly. During our manufacturing process, Moly is added to the column within the generatorwhere it is adsorbed onto alumina powder. The column is sterilized, enclosed in a lead shield and further sealed in a cylindrical plastic container, which isthen immediately shipped to our radiopharmacy customers. Because of the short half-lives of Moly and technetium, radiopharmacies typically purchaseTechneLite 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 radiolabeling 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” below.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 U.S., wehave supply contracts with significant radiopharmacy chains, including Cardinal, UPPI, GE Healthcare and Triad. We also supply generators on a purchaseorder basis with other customers. We estimate that TechneLite had an approximately 40% share of the U.S. generator market as of December 31, 2016,competing primarily with technetium-based generators produced by IBAM. In Puerto Rico, we also supply TechneLite to our owned radiopharmacy toprepare radiopharmaceutical imaging agent unit doses. In Canada, where we sold our radiopharmacies in January 2016, we have a supply agreement withIsologic (the “Isologic Supply Agreement”), the buyer of those radiopharmacies. Under the Isologic Supply Agreement, we will supply Isologic with certainof our products on commercial terms, including certain product purchase commitments by Isologic. The agreement expires in January 2021 and may beterminated upon the occurrence of specified events, including a material breach by the other party, bankruptcy by either party or certain force majeure events.In Australia, where we sold our radiopharmacy servicing business in August 2016, we have a supply agreement with Global Medical Solutions (“GMS”), thebuyer of that business (the “GMS Supply Agreement”). Under the GMS Supply Agreement, we supply GMS with certain of our products on commercial terms,including certain minimum product purchase commitments by GMS. The agreement expires in August 2020 and may be terminated in whole or in part on aproduct-by-product basis upon the occurrence of specified events, including a material breach by the other party, bankruptcy by either party or certain forcemajeure events.The Moly used in our TechneLite generators can be produced using targets made of either highly-enriched uranium (“HEU”) or low-enriched uranium(“LEU”). LEU consists of uranium that contains less than 20% of the uranium-235 isotope. HEU is often considered weapons grade material, with 20% ormore of uranium-235. On 6Table of ContentsJanuary 2, 2013, President Obama signed into law the American Medical Isotopes Production Act of 2012 (“AMIPA”), as part of the 2013 National DefenseAuthorization Act. AMIPA encourages the domestic production of LEU Moly and provides for the eventual prohibition of the export of HEU from the U.S.Although Medicare generally does not provide separate payment to hospitals for the use of diagnostic radiopharmaceuticals administered in an outpatientsetting, since January 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”), the federal agency responsible for administering the Medicareprogram, has provided an add-on payment under the hospital outpatient prospective payment system for every technetium diagnostic dose produced fromnon-HEU sourced Moly, to cover the marginal cost for radioisotopes produced from non-HEU sources. Our LEU TechneLite generator satisfies thereimbursement requirements under the applicable CMS rules.TechneLite has patent protection in the U.S. and various foreign countries on certain component technology currently expiring in 2029. In addition,given the significant know-how and trade secrets associated with the methods of manufacturing and assembling the TechneLite generator, we believe wehave a substantial amount of valuable and defensible proprietary intellectual property associated with the product. We believe that our substantial capitalinvestments in our highly automated TechneLite production line and our extensive experience in complying with the stringent regulatory requirements forthe handling of nuclear materials create significant and sustainable competitive advantages for us in generator manufacturing and distribution. TechneLitegenerated revenues of $99.2 million, $72.6 million and $93.6 million for the years ended December 31, 2016, 2015 and 2014, respectively. TechneLiterepresented approximately 33%, 25% and 31% of our revenues in 2016, 2015 and 2014, 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 a bi-product of Moly production and is processed and finished by us. We are currently the leading provider of Xenon in theU.S. During the years ended December 31, 2016, 2015 and 2014, Xenon Xe 133 Gas represented approximately 10%, 17% and 12% of our revenues,respectively.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,specialized workforce, technical know-how and supplier and customer relationships. • 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. • 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. • Thallium Tl 201 is an injectable radiopharmaceutical imaging agent used in MPI studies to detect cardiovascular disease. We have marketedThallium since 1977 and manufacture the agent using cyclotron technology. • FDG is an injectable, fluorine-18-radiolabeled imaging agent used with PET technology to identify and characterize tumors in patientsundergoing oncologic diagnostic procedures. We manufacture and distribute FDG from our Puerto Rico radiopharmacy. 7Table of Contents • 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. • Quadramet, our only therapeutic product, is an injectable radiopharmaceutical used to treat severe bone pain associated with metastatic bonelesions. We serve as the direct manufacturer and supplier of Quadramet in the U.S.For consolidated revenues and other consolidated financial information for our U.S. and International segments, see Footnote 18, “SegmentInformation” to our accompanying consolidated financial statements.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, United Kingdom, Netherlands, Germany Europe(1), Israel, India(2), 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(3) South Korea, Taiwan, Mexico,Europe(4)Thallium 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 None (1)Other than the United Kingdom, Netherlands, Germany and Austria.(2)JHS is pending approval in India.(3)Excluding Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Italy, Luxembourg, Norway, Slovenia, Spain and Sweden.(4)JHS has regulatory approval pending for Neurolite in Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Italy, Luxembourg, Norway, Slovenia, Spain andSweden.In the U.S. and Canada, we sell DEFINITY through our sales team of 78 employees that call on healthcare providers in the echocardiography space, aswell as group purchasing organizations and integrated delivery networks.Our radiopharmaceutical products are sold in the U.S. through a small nuclear products sales team, primarily to radiopharmacies. We sell a majority ofour radiopharmaceutical products in the U.S. to four 8Table of Contentsradiopharmacy groups—namely Cardinal, UPPI, GE Healthcare and Triad. Our contractual distribution and other arrangements with these radiopharmacygroups are as follows: • Cardinal maintains approximately 131 radiopharmacies that are typically located in large, densely populated urban areas in the U.S. We estimatethat Cardinal’s radiopharmacies distributed approximately 44% of the aggregate U.S. SPECT doses sold in the first half of 2016 (the latestinformation currently available to us). Our written supply agreement with Cardinal relating to TechneLite, Xenon, Neurolite and other productsexpires on December 31, 2017. The agreement specifies pricing levels and requirements to purchase minimum shares of certain products duringcertain periods. The agreement may be terminated upon the occurrence of specified events, including a material breach by the other party andcertain force majeure events. • UPPI is a cooperative purchasing group (roughly analogous to a group purchasing organization) of approximately 77 independently owned orsmaller chain radiopharmacies located in the U.S. UPPI’s radiopharmacies are typically broadly dispersed geographically, with some urbanpresence and a substantial number of radiopharmacies located in suburban and rural areas of the country. We estimate that these independentradiopharmacies, together with an additional 36 unaffiliated, independent radiopharmacies, distributed approximately 26% of the aggregate U.S.SPECT doses sold in the first half of 2016. We currently have an agreement with UPPI for the distribution of TechneLite, Xenon and certain otherproducts to radiopharmacies or families of radiopharmacies within the UPPI cooperative purchasing group. The agreement contains specifiedpricing levels based upon specified purchase amounts for UPPI. We are entitled to terminate the UPPI agreement upon 60 days written notice.The UPPI agreement expires on December 31, 2019. • GE Healthcare maintains 31 radiopharmacies in the U.S. that purchase our TechneLite generators. We estimate that GE Healthcare distributedapproximately 11% of the aggregate U.S. SPECT doses sold in the first half of 2016. We currently have an agreement with GE Healthcare for thedistribution of TechneLite, Xenon and other products. The agreement provides that GE Healthcare will purchase a minimum percentage ofTechneLite generators as well as certain other products from us. Our agreement, which expires on December 31, 2017, may be terminated byeither party on six months’ written notice relating to the other products. Our agreement also allows for termination upon the occurrence ofspecified events including a material breach by either party, bankruptcy by either party or force majeure events. • Triad maintains approximately 56 radiopharmacies in the U.S. that purchase a range of our products. We estimate that Triad distributedapproximately 10% of the aggregate U.S. SPECT doses sold in the first half of 2016. 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 clinics that maintain in-house radiopharmaceutical capabilities and operations. In thelatter case, this represents a small percentage of overall sales because the majority of hospitals and clinics do not maintain these in-house capabilities.In Europe, Australia, Asia Pacific and Latin America, we utilize third party distributor relationships to market, sell and distribute our products, either ona country-by-country basis or on a multi-country regional basis.In March 2012, we entered into a development and distribution arrangement for DEFINITY in China, Hong Kong and Macau with Double-CranePharmaceutical Company (“Double-Crane”). Double-Crane is currently 9Table of Contentspursuing the Chinese regulatory approval required to commercialize DEFINITY. There are three milestones in the regulatory approval process tocommercialize 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 (“CFDA”), in June 2013. The CFDA accepted the Clinical Trial Application forreview in July 2013. • Second, approval of the Clinical Trial Application, at which point Double-Crane can commence three small confirmatory clinical trials—one forabdominal (liver and kidney), one for cardiac and the third a pharmacokinetic study. The CFDA approved the Clinical Trial Application inFebruary 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 2018.We believe that international markets, particularly China, represent significant growth opportunities for our products. The Double-Crane distributionagreement did not have a meaningful impact our revenues during the years ended December 31, 2016 or 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 operated in Australia and the one radiopharmacy we own and operate in Puerto Rico. Currently in Canada, we sell ourproducts through our Isologic Supply Agreement, which we entered into in connection with the sale of our Canadian radiopharmacies in January 2016. Wealso sell our products directly to hospitals with in-house radiopharmacy capabilities. In Australia, we sell our products through our GMS Supply Agreement,which we entered into in connection with the sale of our Australian subsidiary in August 2016.In Puerto Rico, we own and operate one of two radiopharmacies on the island and sell our own products as well as products of third parties to end-users.SeasonalityOur business has modest seasonality as patients may seek to schedule diagnostic imaging procedures less frequently during the summer vacationmonths and over the year-end holidays.CustomersTotal revenues from customers that accounted for 10% or more of our total consolidated revenues are as follows: Year EndedDecember 31, 2016 2015 2014 Cardinal 10.3% 11.3% 18.0% UPPI 11.4% 11.9% 11.1% BacklogOur backlog consists of orders for which a delivery schedule within the next twelve months has been specified. Orders included in backlog may becanceled or rescheduled by customers at any time with the exception of TechneLite orders. For TechneLite, customers must provide us with four weeksadvanced notice to cancel an order. We do not believe that our backlog at any particular time is meaningful because it has historically been immaterialrelative to our total revenue and is not necessarily indicative of future revenues at any given period. 10Table of ContentsCompetitionWe 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 currently include IBAM, GE Healthcare, Bayer AG (“Bayer”), Bracco and DRAXIS SpecialtyPharmaceuticals 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, or bundle the sale of aportfolio of products to the detriment of our specific products. Our current or future products could be rendered obsolete or uneconomical as a result of theseactivities.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, 2016, our largest suppliers of raw materials and supplies were NTP Radioisotopes (“NTP”), actingfor itself and on behalf of ANSTO, and Nordion, accounting for approximately 15% and 14%, respectively, of our total purchases.Molybdenum-99Our TechneLite, Cardiolite and Neurolite products all rely on Moly, the radioisotope which is produced by bombarding uranium 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 three of the four main processing sites in the world, namely, NTP in South Africa; ANSTO in Australia; andInstitute for Radioelements (“IRE”) in Belgium. These processing sites are, in turn, supplied by five of the six main Moly-producing reactors in the world,namely, SAFARI in South Africa; OPAL in Australia; BR2 in Belgium; LVR-15 in the Czech Republic; and High Flux Reactor (“HFR”) in The Netherlands.Historically, our largest supplier of Moly was Nordion, which relied on the NRU reactor in Canada for its supply of Moly. Our agreement with Nordionexpired on October 31, 2016, and from November 2016, the NRU reactor transitioned from providing regular supply of medical isotopes to providing onlyemergency back-up supply of HEU based Moly through March 2018.Our agreement with NTP includes their partner, ANSTO. ANSTO has significantly increased its Moly production capacity from its existing facility inAugust 2016 and has a new Moly processing facility under construction, in cooperation with NTP, that ANSTO believes will expand its production capacityup to 11Table of Contentsapproximately 3,500 six-day Curies/week, which is expected to be in commercial operation in the first half of 2018. The agreement allows for terminationupon the occurrence of certain events, including failure by NTP to provide our required amount of Moly, material breach of any provision by either party,bankruptcy by either party or force majeure events. Additionally, we have the ability to terminate the agreement with six months’ written notice prior to theexpiration of the agreement. The agreement expires on December 31, 2017.In March 2013, we entered into a similar agreement with IRE (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 favorable allocations 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 or force majeure events. The IREAgreement expires on December 31, 2017.In addition, IRE received approval from its regulator to expand its production capability by up to 50% of its former capacity. This new ANSTO andIRE production capacity is expected to replace and exceed the NRU’s most recent routine production. The NTP/ANSTO agreement contains minimumpercentage volume requirements and provides for the increased supply of Moly derived from LEU targets from NTP and ANSTO.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 entered into a strategic agreement with SHINEMedical Technologies, Inc. (“SHINE”), a Wisconsin-based company, for the future supply of Moly. Under the terms of the supply agreement, SHINE willprovide Moly produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomes operational andreceives all necessary regulatory approvals. See Part I, Item 1A. “Risk Factors—The global supply of Moly is fragile and not stable. Our dependence on alimited number of third party suppliers for Moly could prevent us from delivering some of our products to our customers in the required quantities, with therequired timeframe, or at all, which could result in order cancellations and decreased revenues.”XenonHistorically, Nordion was our sole supplier of Xenon, and a principal supplier on a global basis, of Xenon, which is captured as a by-product of theMoly production process. Our agreement with Nordion expired on October 31, 2016. In January 2015, we entered into a new strategic agreement with IRE forthe future supply of Xenon. We are now receiving bulk unprocessed Xenon from IRE, which we are processing and finishing for our customers at our NorthBillerica, Massachusetts manufacturing facility. Until we can qualify an additional source of bulk unprocessed Xenon, we will rely on IRE as a sole sourceprovider. See Part I, Item 1A. “Risk Factors—We face potential supply and 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 Thallium and Gallium using our cyclotron technology, 12Table of Contentsand we process and finish Xenon and Quadramet using our hot cell infrastructure. We manufacture, finish and distribute our radiopharmaceutical products ona just-in-time basis, and supply our customers with these products either by next day delivery services or by either ground or air custom logistics. We believethat our substantial capital investments in our highly automated generator production line, our cyclotrons and our extensive experience in complying withthe stringent regulatory requirements for the handling of nuclear materials and operations in the FDA regulated environment create significant andsustainable 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.Manufacturing and Supply ArrangementsWe currently have the following technology transfer and manufacturing and supply agreements in place for some of our major products: • DEFINITY—In February 2012, we entered into a Manufacturing and Supply Agreement with JHS, for the manufacture of DEFINITY. Under theagreement, JHS manufactures DEFINITY for us for an initial term of five years. In September 2016, we extended the agreement through January2022, including a commitment by JHS to provide us 100% of our DEFINITY volume until July 2018. We have the right to extend the agreementwith automatic renewals for additional one-year periods thereafter. The agreement allows for termination upon the occurrence of certain eventssuch as a material breach or default by either party, or bankruptcy by either party. The agreement also requires us to place orders for a minimumpercentage 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. Ourtechnology transfer activities with Pharmalucence have been repeatedly delayed, and we are now in the process of negotiating an exit to thatarrangement. On May 3, 2016, we entered into a Manufacturing and Supply Agreement with SBL to perform technology transfer and processdevelopment services to manufacture and supply our next generation DEFINITY product. There are no minimum purchase requirements underthis agreement, which has an initial term of five years from the date of first commercial sale and is renewable at our option for an additional fiveyears. This agreement allows for termination upon the occurrence of certain events, including material breach or bankruptcy of either party. Wecannot give any assurances as to when that technology transfer will be completed and when we will actually receive supply of next generationDEFINITY product from SBL. Based on our current projections, we believe that we will have sufficient supply of DEFINITY from JHS to meetexpected demand. • Cardiolite—For the past several years, we have relied on Bristol-Myers Squibb Company’s (“BMS”), Manati, Puerto Rico site for themanufacture of our Cardiolite supply. This relationship ended on December 31, 2015 following the completion of a terminal inventory build forour Cardiolite product. We also entered into a Manufacturing and Supply Agreement, effective as of May 3, 2012, with JHS for the manufactureof Cardiolite products. In the third quarter of 2016, we completed the technology transfer process and received FDA approval to manufactureCardiolite at JHS. Under the agreement, JHS has agreed to manufacture products for an initial term of five years from the effective date. We havethe right to extend the agreement for an additional five-year period, with automatic renewals for additional one-year periods thereafter. Theagreement allows for termination upon the occurrence of specified events, including material breach or bankruptcy by either party. Theagreement requires us to 13Table of Contents place orders for a minimum percentage of our requirements for Cardiolite products with JHS during such term. Based on our current projections,we believe that we will have sufficient Cardiolite products supply to meet expected 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 manufacture Neurolite at JHS. Under the agreement, JHS has agreed to manufacture Neurolite foran initial term of five years from the effective date. We have the contractual right to extend the agreement for an additional five-year period, withautomatic renewals for additional one-year periods thereafter. The agreement allows for termination upon the occurrence of specified events,including material breach or bankruptcy by either party. The agreement also requires us to place orders for a minimum percentage of ourrequirements for Neurolite during such term. Based on our current projections, we believe that we will have sufficient supply of Neurolite fromJHS to meet expected demand.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 Part I, 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, within the required timeframes, or at all, which could result in order cancellations and decreasedrevenues,” Part I, Item 1A. “Risk Factors—Challenges with product quality or product performance, including defects, caused by us or our suppliers couldresult in a decrease in customers and sales, unexpected expenses and loss of market share” and Part I, Item 1A. “Risk Factors—Our business and industry aresubject to complex and costly regulations. If government regulations are interpreted or enforced in a manner adverse to us or our business, we may be subjectto enforcement actions, penalties, exclusion and other material limitations on our operations.”PET Manufacturing FacilitiesIf either one of our clinical-stage PET cardiac imaging agents - flurpiridaz F 18 and 18F LMI 1195 - are ultimately successful in clinical trials, a newmanufacturing model will be required in which chemical ingredients of the imaging agent are provided to PET radiopharmacies that have fluorine-18radioisotope-producing cyclotrons on premises. The radiopharmacies will combine these chemical ingredients with fluorine-18 they manufactured inspecially designed chemistry synthesis boxes to generate the final radiopharmaceutical imaging agent. Radiopharmacists will be able to prepare and dispensepatient-specific doses from the final product. However, because each of these PET radiopharmacies will be deemed by the FDA to be a separate manufacturingsite for the relevant agent, each of the radiopharmacies will have to be included in the agent’s New Drug Application (“NDA”) and subsequent FDA filings.As a result, there will be quality and oversight responsibilities of the PET radiopharmacies associated with the NDA, unlike the current relationship we havewith our nuclear imaging agent distributors that operate radiopharmacies. See “Research and Development—Flurpiridaz F 18 Phase 3 Program and—18FLMI 1195—Cardiac Neuronal Imaging Agent.”Research and DevelopmentFor the years ended December 31, 2016, 2015 and 2014, we invested $12.2 million, $14.4 million and $13.7 million in research and development(“R&D”), respectively. 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 U.S. and numerous foreign jurisdictions.In March 2013, we began to implement a strategic shift in how we fund our important R&D programs, reducing our internal R&D resources. OnFebruary 21, 2017, we announced entering into a term sheet with 14Table of ContentsGE Healthcare relating to the continued development and commercialization of flurpiridaz F 18. In the future, we may also seek to engage strategic partnersfor our 18F LMI 1195 and LMI 1174 programs. See Part I, Item 1A. “Risk Factors—We may not be able to further develop or commercialize our agents indevelopment 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 (“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 3 ProgramTo date, our Phase 3 program for flurpiridaz F 18 has included a phase 3 trial (“301 Trial”), which was an open-label, multicenter, international studywith 755 subjects with known or suspected coronary artery disease (“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 imaging with primary endpoints of superiority forsensitivity (identifying disease) and non-inferiority for specificity (ruling out disease).In March 2011, we obtained agreement from the FDA on a Special Protocol Assessment (“SPA”) for our 301 Trial. See “—Regulatory Matters—Foodand Drug Laws” below. In June 2011, we enrolled our first patient, and we completed patient enrollment in the third quarter of 2013. 15Table of ContentsIn 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 imaging in a highly statistically significant manner on sensitivity. In addition, flurpiridaz F 18 showed statisticallysignificant improvements in image quality and diagnostic certainty in comparison to SPECT imaging. However, flurpiridaz F 18 did not meet the co-primaryendpoint 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 imaging results were skewed with low sensitivity and high specificity when compared to coronary angiography. When the flurpiridaz F 18 imagingresults were compared to the SPECT imaging results, flurpiridaz F 18 imaging substantially outperformed SPECT imaging in sensitivity but did not meet thenon-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 multi-vesseldisease. A significantly higher percentage of images were rated as either excellent or good with flurpiridaz F 18 imaging as compared to SPECT imaging,leading to a greater diagnostic certainty of interpretation. Importantly, radiation exposure associated with flurpiridaz F 18 imaging was reduced toapproximately 50% of SPECT imaging. In addition, 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. See Part I, Item 1A. “Risk Factors—The process of developing new drugs and obtaining regulatoryapproval is complex, time-consuming and costly, and the outcome is not certain.”Proposed GE Healthcare TransactionOn February 21, 2017, we announced entering into a term sheet with GE Healthcare relating to the continued development and worldwidecommercialization of flurpiridaz F 18. Under the proposed transaction, GE Healthcare would fund the second Phase III flurpiridaz F 18 clinical study,worldwide regulatory approvals and its worldwide launch and commercialization, with us collaborating in both development and commercialization througha joint steering committee. We would also maintain the option to co-promote the agent in the U.S. GE Healthcare’s development plan would focus onobtaining regulatory approval in the U.S., Japan, Europe and Canada. We would receive a $5 million upfront cash payment and, if successful, up to $60million in regulatory and sales milestones payments, plus tiered double-digit royalties on U.S. sales and mid-single-digit royalties on sales outside of the U.S.Subject to satisfactory due diligence and necessary approvals, we anticipate entering into a definitive agreement for the proposed transaction in the secondquarter of 2017. However, there is no assurance that we will enter into a definitive agreement on these terms or at all. See Part I, Item 1A. “Risk Factors—Wemay not be able to further develop or commercialize our agents in development without successful strategic partners.”18F LMI 1195—Cardiac Neuronal 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 U.S. alone, there are over five million patients living with congestive heart failure, and over a half million newdiagnoses each year. 16Table of ContentsMortality for this condition is around 50% within five years of diagnosis. Expensive therapies for heart failure are often utilized without effective predictorsof patient response. Costly device therapies (for example, implantable cardiac defibrillators (“ICDs”), and cardiac resynchronization therapy) are often used,although they sometimes do not provide any benefits or are activated in only a minority of recipients. Conversely, heart failure clinical practice guidelinescurrently preclude the use of device therapy in many patients who might benefit. Thus, a key opportunity is to better match patients to treatment based on theidentification 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 U.S., Canada and Europe to develop additional clinical data which may allow us to enter into pivotal clinical trials.LMI 1174—Vascular Remodeling Imaging AgentWe have developed LMI 1174, an internally discovered gadolinium-based magnetic resonance imaging (“MRI”) agent targeted to elastin in thearterial walls and atherosclerotic plaque. We believe that this agent could allow assessment of plaque location, burden, type of arterial wall remodeling and,as a result, the potential for a vascular 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 currently working closely with investigators in theU.S. and Europe to develop additional preclinical data which may allow us to enter into clinical trials.Intellectual PropertyPatents, trademarks and other intellectual property rights, both in the U.S. and foreign countries, are very important to our business. We also rely ontrade secrets, manufacturing know-how, technological innovations and licensing agreements to maintain and improve our competitive position. We reviewthird party proprietary rights, including patents and patent applications, as available, in an effort to develop an effective intellectual property 17Table of Contentsstrategy, avoid infringement of third party proprietary rights, identify licensing opportunities and monitor the intellectual property owned by others. Ourability to enforce and protect our intellectual property rights may be limited in certain countries outside the U.S., 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. See Part I, Item 1A. “Risk Factors—If we are unable to protect our intellectual property, ourcompetitors could develop and market products with features similar to our products, and demand for our products may decline.”Trademarks, Service Marks and Trade NamesWe own various trademarks, service marks and trade names, including DEFINITY, TechneLite, Cardiolite, Neurolite, Vialmix, Quadramet (U.S. only)and Lantheus Medical Imaging. We have registered these trademarks, as well as others, in the U.S. 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 U.S., we file patent applications in numerous foreign countries in order to further protect the inventions that we consider important to the development ofour international business. We also rely upon trade secrets and contracts to protect our proprietary information. As of January 31, 2017, our patent portfolioincluded a total of 34 issued U.S. patents, 205 issued foreign patents, 23 pending patent applications in the U.S. and 161 pending foreign applications. Thesepatents and patent applications 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 U.S., Canada, Mexico, most of WesternEurope, various markets in Asia, and Brazil. For DEFINITY, we hold a number of different compositions of matter, use, formulation and manufacturingpatents. In the U.S., we have a composition of matter patent expiring in 2019 and a manufacturing patent expiring in 2021. Outside of the U.S., we havepatent or regulatory extension protection in Canada, Europe and parts of Asia until 2019. We also have an active next generation development program forthis agent. TechneLite currently has patent protection in the U.S. and various foreign countries on certain component technology 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. Neither Cardiolite norNeurolite is covered any longer by patent protection in either the U.S. or the rest of the world. Xenon, Thallium and Gallium have no patent protection;however, we are pursuing patent protections for an improved container for Xenon.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 U.S. a composition patent expiring in 2026, amethod of use patent expiring in 2028 and a method of manufacturing patent expiring in 2031, in the absence of any regulatory extension, and variouspatent 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 U.S. a composition patent expiring in 2030 in theabsence of any regulatory extension, and patent applications which, if granted, will expire in 2027 and in 2031 in the absence of any patent term adjustmentor regulatory extensions. Additionally, we have patents and patent applications in numerous jurisdictions covering composition, use and manufacture of LMI1174, our vascular 18Table of Contentsremodeling imaging agent, including in the U.S. a composition and method of use patent expiring in 2031 in the absence of any regulatory extension, andpatent applications which, if granted, will expire in 2029 and 2030 in the absence of any patent term adjustment 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 provide assurances that an employee or an outsideparty will not make an unauthorized disclosure of our trade secrets, other technical know-how or proprietary information. We may not have adequatemonitoring abilities to discover, or adequate remedies for, any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that acompetitor will make use of such information, and that our competitive position will be compromised, in spite of any legal action we might take againstpersons making such unauthorized disclosures. In addition, our trade secrets may otherwise become known or be independently discovered by competitors.To the extent that our collaborators, employees and consultants use intellectual property owned by others in their work for us, disputes may arise as to therights in related or resulting 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 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 related to the development, manufacture, packaging or repackaging of our pharmaceutical and medical device products subject us to awide variety 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 (“NRC”), the U.S. Department of Health and Human Services (“HHS”), Health Canada, theEuropean Medicines Agency (“EMA”), the U.K. Medicines and Healthcare Products Regulatory Agency (“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 19Table of Contentsand sales and distribution of pharmaceutical products in the U.S. Prior to marketing a pharmaceutical product, we must first receive FDA approval. In the U.S.,the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations. The process of obtaining regulatoryapprovals and compliance with appropriate federal, state, local, and foreign statutes and regulations requires the expenditure of substantial time and financialresources. Currently, the process required by the FDA before a drug product may be marketed in the U.S. 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 an 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 (“cGMPs”) regulations; and • FDA review and approval of the NDA.The 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 and excretion. In the case of some products for severe or life-threatening diseases, especially when the agent may be too inherentlytoxic to ethically administer 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 theefficacy of the 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 atgeographically dispersed clinical study sites. These studies are intended to collect sufficient safety and effectiveness data to support the NDA forFDA 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. 20Table of ContentsProgress 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 (“IRB”), serving any of the institutions participating in theclinical trial can suspend or terminate approval of a clinical study at a relevant institution if the clinical study is not being conducted in accordance with theIRB’s requirements or if the agent has been associated with unexpected serious harm to patients. Failure to register a clinical trial or disclose study resultswithin the required 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.The 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(“PDUFA”), which was first enacted in 1992 to provide the FDA with additional resources to speed the review of important new medicines. A waiver of thatfee may be obtained under certain limited circumstances. PDUFA expires every five years and must be reauthorized by Congress. The current version ofPDUFA, the fifth reauthorization (“PDUFA V”), was renewed as Title I of the FDA Safety and Innovation Act in 2012 and is scheduled to expire in 2017.PDUFA V focuses on improving the efficiency and predictability of the review process, strengthening the agency regulatory science base and enhancingbenefit-risk assessment and post-approval safety surveillance. The next reauthorization of PDUFA in 2017 may bring changes or additions to regulatoryrequirements for drugs and medical devices regulated under the FDCA. In December 2016, Congress enacted and President Obama signed the 21st CenturyCures bill into law. That law contains a number of provisions that may change regulatory requirements for drugs and medical devices. Given its recentenactment, as well as the change in the federal Administration, it is uncertain how the law will be implemented. Therefore, it is also uncertain whether or towhat extent any changes or additions to regulatory requirements authorized by the new law will have an impact on the regulation of drugs or medicaldevices.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 21Table of Contentsproduct labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to further assess a drug product’s safety andeffectiveness after NDA approval. The FDA also may impose a Risk Evaluation and Mitigation Strategy (“REMS”) to ensure that the benefits of a productoutweigh its risks. A REMS could add training requirements for healthcare professionals, safety communications efforts and limits on channels ofdistribution, among other things. The sponsor would be required to evaluate and monitor the various REMS activities and adjust them if need be. Whether aREMS 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.Drug 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 (“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, post-market 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 22Table of Contentsdepartments of health of each state in which we operate and the applicable state boards of pharmacy. In addition, the FDA is also involved in the regulationof cyclotron facilities where PET products are produced in compliance with cGMP requirements and U.S. Pharmacopeia requirements for PET drugcompounding.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, we investigatethe issue and take appropriate corrective action, such as withdrawal of the product from the market, correction of the product at the customer location, noticeto 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) 23Table of ContentsNDA for a period of five years from the date of approval of the NDA, except that the FDA may accept an application for review after four years under certaincircumstances. The Hatch-Waxman Act 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 be required to conduct its own clinical trials, and any use of the drug for which marketing approval is sought could not violateanother NDA holder’s patent claims. The Hatch-Waxman Act provides for a three-year period of exclusivity for an NDA for a new drug containing an activemoiety that was previously approved by the FDA, but also includes new clinical data (other than bioavailability and bioequivalence studies) to support aninnovation over the previously approved drug and those studies were conducted or sponsored by the applicant and were essential to approval of theapplication. This three-year exclusivity period does not prohibit the FDA from accepting an application from a third party for a drug with that sameinnovation, but it does prohibit the FDA from approving that application for the three-year period. The three-year exclusivity does not prohibit the FDA, withlimited exceptions, from approving generic drugs containing the same active ingredient but without the new innovation.Healthcare Reform and Other Laws Affecting PaymentWe operate in a highly-regulated industry. The U.S. and state governments continue to propose and pass legislation that may affect the availability andcost of healthcare. For example, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, orcollectively, the Healthcare Reform Act, substantially changes the way in which healthcare is financed by both governmental and private insurers and has asignificant impact on the pharmaceutical industry. The Healthcare Reform Act contains a number of provisions that affect coverage and reimbursement ofdrug products and the medical 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: (which tax appliedto applicable sales made from January 1, 2013 through December 31, 2015, but is currently suspended for 2016 and 2017).The Healthcare Reform Act also establishes an Independent Payment Advisory Board (“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 through 2016, sono adjustments will be made under the IPAB until 2019 (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 (“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. 24Table of ContentsThe Healthcare Reform Act has been subject to political and judicial challenges. In 2012, the U.S. Supreme Court considered the constitutionality ofcertain provisions of the law. The U.S. Supreme Court upheld as constitutional the mandate for individuals to obtain health insurance, but held the provisionallowing the federal government to withhold certain Medicaid funds to states that do not expand state Medicaid programs unconstitutional. Therefore, not allstates have expanded their Medicaid programs under the Healthcare Reform Act. Political and judicial challenges to the law have continued in the wake ofthe Court’s ruling.Modification to or repeal of all or certain provisions of the Healthcare Reform Act are expected as a result of the outcome of the recent presidentialelection and Republicans maintaining control of Congress, consistent with statements made by Donald Trump and members of Congress during thepresidential campaign and following the election. We cannot predict the ultimate content, timing or effect of any changes to the Healthcare Reform Act orother federal and state reform efforts. There is no assurance that federal or state health care reform will not adversely affect our future business and financialresults, and we cannot predict how future federal or state legislative, judicial or administrative changes relating to healthcare reform will affect our business.General legislative cost control measures may also affect reimbursement for our products. The Budget Control Act, as amended, resulted in theimposition of 2% reductions in Medicare (but not Medicaid) payments to providers in 2013 and will remain in effect through 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 could have an adverse impact on our results of operations.Healthcare 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 criminal or civil sanctions, including fines and civil monetary penalties, and/or exclusionfrom federal health care programs (including Medicare and Medicaid). Federal and state authorities are paying increased attention to enforcement of theselaws within the pharmaceutical industry, and private individuals have been active in alleging violations of the laws and bringing suits on behalf of thegovernment under the federal False Claims Act (“FCA”). Violations of international fraud and abuse laws could result in similar penalties, includingexclusion from participation in health programs outside the U.S. 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. The Healthcare Reform Act clarifies theintent requirements of the federal Anti-Kickback Statute, providing that a person or entity does not need to have actual knowledge of the statute or a specificintent to violate the statute. Violations of the federal Anti-Kickback Statute can result in exclusion from Medicare, Medicaid or other governmental programsas well as civil and criminal fines and penalties of up to $50,000 per violation and three times the amount of the unlawful remuneration. 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. The majority of states also have anti-kickback, false claims, and similar fraud and abuse laws and although the specificprovisions of these laws vary, their scope is generally broad, and there may not be regulations, guidance or court decisions that apply the laws to particularindustry practices. There is therefore a possibility that our practices might be challenged under the anti-kickback statutes or similar laws.Federal and state false claims laws generally prohibit anyone from knowingly and willfully, 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 25Table of Contentsprovided as claimed or claims for medically unnecessary services). False or fraudulent claims for purposes of the FCA carry fines and civil penalties forviolations ranging from $10,781 to $21,563 for each false claim, plus up to three times the amount of damages sustained by the federal government and, mostcritically, may provide the basis for exclusion from federally funded healthcare programs. There is also a criminal FCA statute by which individuals orentities that submit false claims can face criminal penalties. In addition, under the federal Civil Monetary Penalty Law, the Department of Health and HumanServices Office of Inspector General has the authority to exclude from participation in federal health care programs or to impose civil penalties against anyperson who, among other things, knowingly presents, or causes to be presented, certain false or otherwise improper claims. Our activities relating to the saleand 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”).The Healthcare Reform Act requires manufacturers to submit information to the FDA on the identity and quantity of drug samples requested and distributedby a manufacturer during each year. Recent scrutiny of pharmaceutical pricing practices by certain companies may lead to changes in laws that currentlyallow substantial flexibility in pricing decisions by pharmaceutical manufacturers. Such changes could occur at the federal level or state level and may beadopted by statute, rule, or sub-regulatory policies. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures.Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. Given the lack of clarity in lawsand their implementation, our activities could be subject to the penalty provisions of the pertinent federal and state laws and regulations.Other Healthcare LawsOur operations may be affected by the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) as amended by the Health InformationTechnology for Economic and Clinical Health Act and its implementing regulations (“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 (“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 (“Bribery Act”) which proscribes giving and receiving bribes in the public and private sectors, bribing aforeign public official, and failing to have adequate procedures to 26Table of Contentsprevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom generally will be subject to the BriberyAct. Penalties under the Bribery Act include potentially unlimited fines for companies and criminal sanctions for corporate officers under certaincircumstances.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 U.S. and abroad, relating to safe workingconditions, 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 the U.S.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 and wastes. If we violatethese laws and regulations, we could be fined, criminally charged or otherwise sanctioned by regulators. We believe that our operations currently comply inall material respects with applicable environmental laws and regulations. See Part I, Item 1A. “Risk Factors—We use hazardous materials in our business andmust comply with environmental laws and regulations, which can be expensive.”Certain 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, Massachusetts facility, which is ourprimary manufacturing, packaging and distribution facility. In particular, we must maintain a nuclear byproducts materials license issued by theCommonwealth of Massachusetts. This license requires that we provide financial assurance demonstrating our ability to cover the cost of decommissioningand decontaminating (“D&D”) the Billerica site at the end of its use as a nuclear facility. In addition, we have a radioactive production facility in San Juan,Puerto Rico. As of December 31, 2016, we currently estimate the D&D cost to be approximately $26.9 million. As of December 31, 2016 and 2015, we have aliability recorded associated with the fair value of the asset retirement obligations of approximately $9.4 million and $8.1 million, respectively. We haverecorded accretion expense of $0.9 million, $0.7 million and $0.8 million during the years ended December 31, 2016, 2015 and 2014, respectively. Wecurrently provide this financial assurance in the form of surety bonds. We generally contract with third parties for the disposal of wastes generated by ouroperations. Prior to disposal, we store any low level radioactive waste at our facilities until the materials are below regulatory limits, as allowed by ourlicenses 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 27Table of Contentsprotection, health and safety laws and regulations will not exceed our estimates or adversely affect our results of operations and financial condition. Further,we cannot assure you that we will not be subject to additional environmental claims for personal injury or cleanup in the future based on our past, present orfuture business activities. While it is not feasible to predict the future costs of ongoing environmental compliance, it is possible that there will be a need forfuture provisions for environmental costs that, in management’s opinion, are not likely to have a material effect on our financial condition, but could bematerial to the results of operations in any one accounting period.EmployeesAs of January 31, 2017, we had 465 employees, of which 421 were located in the U.S. and 44 were located internationally, and approximately 78contractors. None of our employees are represented by a collective bargaining agreement, 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 E.I. du Pont de Nemours andCompany (“DuPont”) in 1981. BMS subsequently acquired our diagnostic medical imaging business as part of its acquisition of DuPont Pharmaceuticals in2001. In January 2008, Avista Capital Partners, L.P., Avista Capital Partners (Offshore), L.P. and ACP-Lantern Co-Invest, LLC (collectively “Avista”) formedLantheus Holdings and its subsidiary, Lantheus Intermediate, and, through Lantheus Intermediate, acquired our medical imaging business from BMS. OnJune 30, 2015, the Company completed an initial public offering (“IPO”) of its common stock. Immediately prior to the consummation of the Company’sIPO, Lantheus MI Intermediate merged with and into Lantheus Holdings, Inc., which was the survivor of the merger. The Company’s common stock is nowtraded on the NASDAQ Global Market under the symbol “LNTH”.Executive Officers of the RegistrantThe following table sets forth information regarding our executive officers, including their ages as of the date of this report: Name Age Position Mary Anne Heino 57 Chief Executive Officer, President and Director Jack Crowley 53 Chief Financial Officer and Treasurer William Dawes 45 Vice President, Manufacturing and Operations Michael Duffy 56 Senior Vice President, Strategy and Business Development, General Counsel and Secretary Timothy Healey 51 Senior Vice President, Commercial Dr. Cesare Orlandi 66 Chief Medical Officer Dr. Simon Robinson 57 Vice President, Research and Development Carol Walker 54 Vice President, QualityMary Anne Heino has served as our Chief Executive Officer and Director since August 2015.

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 on Form 10-K.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, Cardiolite and evacuation vials. Our technology 30Table of Contentstransfer activities with Pharmalucence for the manufacture and supply of DEFINITY have been repeatedly delayed, and we are now in the process ofnegotiating an exit to that arrangement. We currently have additional on-going technology transfer activities for our next generation DEFINITY product withSBL, but we cannot give any assurances as to when that technology transfer will be completed and when we will actually receive supply of next generationDEFINITY product from SBL. Currently, our DEFINITY, Neurolite, Cardiolite, evacuation vial and saline product supplies are approved for manufacture by asingle manufacturer.Based on our current estimates, we believe that we will have sufficient supply of DEFINITY, Neurolite, Cardiolite and evacuation vials from JHS, andsufficient supply of saline from our sole manufacturer, to meet expected demand. However, we can give no assurances that JHS or our other manufacturingpartner will be able to manufacture and distribute our products in a high quality and timely manner and in sufficient quantities to allow us to avoid productstock-outs and shortfalls. Currently, regulatory authorities in certain countries have not yet approved JHS as a manufacturer of certain of our products.Accordingly, until those regulatory approvals have been obtained, our international business, results of operations, financial condition and cash flows willcontinue to be adversely affected.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 and Quadramet using our hot cellinfrastructure. As with all manufacturing facilities, equipment and infrastructure age and become subject to increasing maintenance and repair. If we or one ofour manufacturing partners experiences an event, including a labor dispute, natural disaster, fire, power outage, machinery breakdown, security problem,failure to meet regulatory requirements, product quality issue, technology transfer issue or other issue, we may be unable to manufacture the relevant productsat previous levels or on the forecasted schedule, if at all. Due to the stringent regulations and requirements of the governing regulatory authorities regardingthe manufacture of our products, we may not be able to quickly restart manufacturing at a third party or our own facility or establish additional orreplacement 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. Our technology transfer activities with Pharmalucence for the manufacture and supply of DEFINITY havebeen repeatedly delayed, and we are now in the process of negotiating an exit to that arrangement. We currently have additional on-going technologytransfer activities for our next generation DEFINITY product with SBL, but we cannot assure you that these activities or any of our additional supplyactivities will be successful or that we will be able to avoid or mitigate interim supply shortages before those new manufacturers or sources of product arefully functional and qualified. In addition, we cannot assure you that our existing manufacturers or suppliers or any new manufacturers or suppliers canadequately maintain either their financial health or regulatory compliance to allow continued production and supply. A reduction or interruption inmanufacturing, or an inability to secure alternative sources of raw materials or components, could eventually have a material adverse effect on our business,results of operations, financial condition and cash flows.Challenges with product quality or product performance, including defects, caused by us or our suppliers could result in a decrease in customers andrevenues, 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 31Table of Contentsincluding 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 in an unsafecondition 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 also mayundertake voluntarily to recall products or temporarily shut down 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.The 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 three of thefour main processing sites in the world, namely NTP in South Africa; ANSTO in Australia; and IRE in Belgium. These processing sites are, in turn, suppliedby five of the six main Moly-producing reactors in the world, namely, OPAL in Australia; BR2 in Belgium; LVR-15 in the Czech Republic; HFR in TheNetherlands; and SAFARI in South Africa.Historically, our largest supplier of Moly was Nordion, which has relied on the NRU reactor owned by Atomic Energy of Canada Limited (“AECL”), aCrown corporation of the Government of Canada, located in Chalk River, Ontario. As a result of a decision by the Government of Canada, the NRU reactor isexiting the medical isotope business and beginning in November 2016 will provide only emergency back-up Moly supply through March 2018.ANSTO has under construction, in cooperation with NTP, a new Moly processing facility that ANSTO believes will expand its production capacity byapproximately 2.5 times, with commercial production planned to start in the first half of 2018. In addition, IRE received approval from its regulator to expandits production capability by up to 50% of its former capacity. This new ANSTO and IRE production capacity is expected to replace the NRU’s most recentroutine production. While we believe this additional Moly supply now gives us the most balanced and diversified Moly supply chain in the industry, aprolonged disruption of service from only one of our Moly suppliers could have a material adverse effect on our business, results of operations, financialcondition and cash flows. We are also pursuing additional sources of Moly from potential new producers around the world to further augment our currentsupply. In November 2014, we entered into a strategic agreement with SHINE for the future supply of Moly. Under the terms of the supply agreement, SHINEwill provide Moly produced using its proprietary LEU-solution technology for use in our TechneLite generators once SHINE’s facility becomes operationaland receives all necessary regulatory approvals, which SHINE currently estimates will occur in 2019. However, we cannot assure you that SHINE or any otherpossible additional sources of Moly will result in commercial quantities of Moly for our business, or that these new suppliers together with our currentsuppliers will be able to deliver a sufficient quantity of Moly to meet our needs. 32Table of ContentsU.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 at least 2018.As a result, there is a limited amount of Moly available which could limit the quantity of TechneLite that we could manufacture, sell and distribute, resultingin 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 (“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.Our 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 U.S., over 31.8 million in 2016, based on medical literature, a thirdparty source estimates that 20%, or approximately 6.4 million echocardiograms in 2016, produced suboptimal images. We estimate that DEFINITY had anapproximately 80% share of the U.S. market for contrast agents in echocardiography procedures as of December 2016. If we are not able to continue to growDEFINITY sales through increased market penetration, we will not be able to grow the revenue and cash flow of the business or share the substantial overheadof the balance of our business, which could have a negative effect on our prospects.We face potential supply and demand challenges for Xenon.Historically, Nordion was our sole supplier, and a principal supplier on a global basis, of Xenon, which is captured as a by-product of the Molyproduction process. In January 2015, we entered into a strategic agreement 33Table of Contentswith IRE for the supply of Xenon. We are now receiving bulk unprocessed Xenon from IRE, which we are processing and finishing for our customers. Webelieve we will have sufficient supply of Xenon to meet our customers’ needs. However, until we can qualify an additional source of bulk unprocessedXenon, we will rely on IRE as a sole source provider. For the year ended December 31, 2016, Xenon represented approximately 9.6% of our revenues.Historically, several companies, including IBAM, sold packaged Xenon as a pulmonary imaging agent in the U.S., but from 2010 through the firstquarter of 2016 we were the only supplier of this imaging agent in the U.S. In March 2016, IBAM received regulatory approval from the FDA to again sellpackaged Xenon in the U.S. and has begun to do so. Depending upon the pricing, extent of availability and market penetration of IBAM’s offering, webelieve we are at risk for volume loss and price erosion from those customers which are not subject to price or volume commitments with us.In addition to IBAM again selling 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(“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.Since 2014, Draxis has instituted multiple and substantial price increases for MAA. The increased price of MAA, or difficulties in obtaining MAA, coulddecrease the frequency in which MAA is used for lung perfusion evaluation, in turn, decreasing the frequency that Xenon is used for pulmonary functionevaluation, resulting in a negative effect on our business, results of operations, financial condition and cash flows.In the U.S., 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 U.S., we rely primarily on distributors to generate a substantial portion of our revenue.In the U.S., we have historically relied on a limited number of radiopharmacy customers, primarily Cardinal, UPPI, GE Healthcare and Triad, todistribute our current largest volume nuclear imaging products and generate a majority of our revenues. Three customers accounted for approximately 30% ofour revenues in the year ended December 31, 2016, with UPPI, Cardinal, and GE Healthcare accounting for approximately 11%, 10% and 9%, respectively.Among the existing radiopharmacies in the U.S., continued consolidations, divestitures and reorganizations may have a negative effect on our business,results of operations, financial condition or cash flows. We generally have distribution arrangements with our major radiopharmacy customers pursuant tomulti-year contracts, each of which is subject to renewal. If these contracts are terminated prior to expiration of their term, or are not renewed, or are renewedon 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 andcash flows.In Puerto Rico, we own and operate one of two radiopharmacies on the island and sell our own products as well as products of third parties to end users.For all of our medical imaging products, we continue to experience significant pricing pressures from our competitors, large customers and grouppurchasing organizations, and any significant, additional pricing pressures could lead to a reduction in revenue which could have a material adverse effect onour business, results of operations, financial condition and cash flows.Outside of the U.S., Canada and Puerto Rico, we have no sales force and, consequently, rely on third party distributors, either on a country-by-countrybasis or on a multi-country, regional basis, to market, sell and distribute our products. This is the case in both Canada and Australia, where we formerly ownedor operated 34Table of Contentsradiopharmacies and are now distributing products under the Isologic Agreement and the GMS Agreement, respectively. Distributors accounted forapproximately 34%, 15% and 17% of International segment revenues for the years ended December 31, 2016, 2015 and 2014, respectively. In certaincircumstances, distributors may also sell competing products to our own or products for competing diagnostic modalities and may have incentives to shiftsales towards those competing products. As a result, we cannot assure you that our international distributors will increase or maintain our current levels ofunit sales or increase or maintain our current unit pricing, which, in turn, could have a material adverse effect on our business, results of operations, financialcondition and cash flows.We have a history of net losses and total stockholders’ deficits which may continue and which may negatively impact our ability to achieve orsustain profitability.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 and 2014 of $14.7 million and $3.6 million, respectively, and as of December 31, 2016, we had a total stockholders’ deficit of$106.5 million. Although we had net income of $26.8 million for the year ended December 31, 2016, we cannot assure you that we will be able to sustainprofitability on a quarterly or annual basis in the future. If we cannot improve our profitability, the value of our enterprise may decline.We 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, IBAM, Bayer and Draxis, as well as other competitors. We cannot anticipate their actions in the same or competingdiagnostic modalities, such as significant price reductions on products that are comparable to our own, development or introduction of new products that aremore cost-effective or have superior performance than our current products, the introduction of generic versions when our proprietary products lose theirpatent protection or the new entry into a generic market in which we are already a participant. In addition, distributors of our products could attempt to shiftend-users to competing diagnostic modalities and products. Our current or future products could be rendered obsolete or uneconomical as a result of theseactivities. Our failure to compete effectively could cause us to lose market share to our competitors and have a material adverse effect on our business, resultsof operations, financial condition and cash flows.Xenon for lung ventilation diagnosis is our third largest product by revenue. Historically, several companies, including IBAM, sold packaged Xenonas a pulmonary imaging agent in the U.S., but from 2010 through the first quarter of 2016, we were the only supplier of this imaging agent in the U.S. InMarch 2016, IBAM received regulatory approval from the FDA to again sell packaged Xenon in the U.S. and has begun to do so. Depending upon thepricing, extent of availability and market penetration of IBAM’s offering, we believe we are at risk for volume loss and price erosion for those customerswhich are not subject to price or volume commitments. See Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results ofOperations—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 U.S. and other countries in which we operate, and reductions in third party coverage and reimbursement rates for our products (or sources providedwith 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 35Table of Contentsdiscounted rates and other requirements that may reduce demand for our products. Our potential customers’ ability to obtain appropriate reimbursement forproducts and services from these third party payors affects the selection of products they purchase and the prices they are willing to pay. For example, certainradiopharmaceuticals, when used for non-invasive imaging of the perfusion of the heart for the diagnosis and management of patients with known orsuspected coronary artery disease, are currently subject to a Medicare National Coverage Determination (“NCD”). The NCD permits the coverage of suchradiopharmaceuticals only when certain criteria are met. Our pipeline products, including flurpiridaz F 18, if approved, may become subject to this NCD, andmay not be covered at all. If Medicare and other third party payors do not provide appropriate reimbursement for the costs of our products (or servicesprovided using our products), deny the coverage of the products (or those services), or reduce current levels of reimbursement, healthcare professionals maynot prescribe 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 certain alternative payment models designated as “advanced” by CMS. 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 36Table of Contentsshifting of where certain medical imaging procedures are performed, from the physician office and free-standing imaging facility settings to the hospitaloutpatient setting. Changes applicable to Medicare payment in the hospital outpatient setting could also influence the decisions by hospital outpatientphysicians to perform procedures that involve our products. Within the hospital outpatient setting, CMS has revised its payment policy such that the use ofmany of our products are not separately payable by Medicare, although new drug products are eligible for separate payment for a portion of the drugproducts’ costs and certain products may trigger an additional nominal payment. Specifically, since 2013, although Medicare generally does not provideseparate payment to hospitals for the use of diagnostic radiopharmaceuticals administered in an outpatient setting, CMS has had a policy to make a nominaladditional payment ($10) to hospitals that utilize products with non-HEU, meaning the product is 95% derived from non-HEU sources. This payment policycontinues in 2017. Although some of our TechneLite generators are manufactured using non-HEU, not all of our TechneLite generators meet CMS’sdefinition of non-HEU, and therefore this payment is not available for doses produced by the latter category of TechneLite generators used by our customers.This payment as well as other changes to the Medicare hospital outpatient prospective payment system payment rates could influence the decisions byhospital outpatient physicians to perform 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. Federal legislation requires CMS todevelop appropriate use criteria (“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 2018, payment willbe 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 U.S., ourbusiness, results of operations, financial condition and cash flows would be adversely affected. See Part I, Item I. “Business—Regulatory Matters.”Reforms to the U.S. healthcare system may adversely affect our business.A significant portion of our patient volume is derived from U.S. government healthcare programs, principally Medicare, which are highly regulated andsubject to frequent and substantial changes. For example, in March 2010, the President signed one of the most significant healthcare reform measures indecades, the Healthcare Reform Act. The Healthcare Reform Act substantially changed the way healthcare is financed by both governmental and privateinsurers. The law contains a number of provisions that affect coverage and reimbursement of drug products and medical imaging procedures in which ourdrug products are used and/or that could potentially reduce the aggregate number of diagnostic medical imaging procedures performed in the U.S. See Part I,Item 1. “Business—Regulatory Matters—Healthcare Reform and Other Laws Affecting Payment.” More recently, the Medicare Access and CHIPReauthorization Act of 2015 significantly revised the methodology for updating Medicare physician fee schedule. Congress continues to consider otherhealthcare reform legislation. There is no assurance that the Healthcare Reform Act, as currently enacted or as amended in the future, will not adversely affectour business and financial results, and we cannot predict how future federal or state legislative, judicial or administrative changes relating to healthcarereform 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 37Table of Contentsfederal deficit. These provisions have resulted in the imposition of 2% reductions in Medicare payments to providers, which went into effect on April 1, 2013and will remain in effect through 2024, and a 4% reduction in payment to providers during the first half of 2025 unless additional Congressional action istaken. Any significant spending reductions affecting Medicare, Medicaid or other publicly funded or subsidized health programs that may be implementedand/or any significant taxes or fees that may be imposed on us, as part of any broader deficit reduction effort or legislative replacement to the Budget ControlAct, could have an adverse impact on our results of operations.Further, changes in payor mix and reimbursement by private third party payors may also affect our business. Rates paid by some private third partypayors are based, in part, on established physician, clinic and hospital charges and are generally higher than Medicare payment rates. Reductions in theamount of reimbursement paid for diagnostic medical imaging procedures and changes in the mix of our patients between non-governmental payors andgovernment 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.The full impact on our business of healthcare reforms and other new laws, or changes in existing laws, is uncertain. Nor is it clear whether additionallegislative changes will be adopted or how those changes would affect our industry in general or our ability to successfully commercialize our products ordevelop new products.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 U.S. as well as non-U.S. and transnational laws and regulations, with regulationsdiffering from country to country. In the U.S., 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 export of drug products. We arerequired 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 provincialagencies.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 U.S., 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 compliance with cGMPs and other applicable law, and, from time to time, makes those cGMPs morestringent. Accordingly, we and others with whom we work must expend time, money, and effort in all areas of regulatory compliance, includingmanufacturing, production and quality control. For example, we currently rely on JHS as our sole manufacturer of DEFINITY, Neurolite, Cardiolite andevacuation vials. In 2013, JHS received a warning letter from the FDA in connection with their manufacturing facility in Spokane, Washington where ourproducts are manufactured. Although the FDA upgraded JHS’s compliance status 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 issues arise, the FDA could take additional regulatory action which could limit orsuspend the ability of JHS to manufacture our products or 38Table of Contentshave any additional products approved at the Spokane facility for manufacture until the issues are resolved and remediated. Such a limitation or suspensioncould have a material adverse 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, andin 2016 entered into a separate Medicaid Drug Rebate Agreement for the balance of our products. These agreements require us to report certain priceinformation to the federal government that could subject us to potential liability under the FCA, civil monetary penalties or liability under other laws andregulations in connection with the covered products as well as the products not at the time covered by the agreements. Determination of the rebate amountthat we pay to state Medicaid programs for our products, as well as determination of payment amounts for some of our products under Medicare and certainother third party payers, including government payers, depends upon information reported by us to the government. In 2016, CMS published final rules onthe determination and reporting of average manufacturer price and best price. If we provide customers or government officials with inaccurate informationabout the products’ pricing or eligibility for coverage, or the products fail to satisfy coverage requirements, we could be terminated from the rebate program,be excluded from participation in government healthcare programs, or be subject to potential liability under the False Claims Act or other laws andregulations. See Part I, Item 1. “Business—Regulatory Matters—Healthcare Fraud and Abuse Laws.”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.Our 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 U.S., and evenalleged violations can result in the imposition of corporate integrity agreements that could severely restrict or limit our business practices. See Part I, Item 1.“Business-Regulatory Matters-Healthcare Fraud and Abuse Laws and Laws Relating to Foreign Trade.” These 39Table of Contentslaws 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.If our operations are found to be in violation of these laws or any other government regulations that apply to us, we may be subject to penalties,including, without limitation, civil and criminal penalties, damages, fines, imprisonment, the curtailment or restructuring of our operations, or exclusion fromstate and federal healthcare programs including Medicare and Medicaid, any of which could have a material adverse effect on our business, results ofoperations, financial condition and cash flows.Ultrasound 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 butnon-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 40Table of Contentsa timely manner would have an adverse effect 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.The 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 Part I, Item 1. “Business—Regulatory Matters.” Satisfaction of allregulatory requirements typically takes many years and requires the expenditure of substantial resources. A number of other factors may cause significantdelays in the completion of our clinical trials, including unexpected delays in the initiation of clinical sites, slower than projected enrollment, competitionwith ongoing clinical trials and scheduling conflicts with participating clinicians, regulatory requirements, limits on manufacturing capacity and failure of anagent to meet required standards for administration to humans. In addition, it may take longer than we project to achieve study endpoints and complete dataanalysis for a trial 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 41Table of Contentsclinical testing. Further, the data collected from clinical trials of our agents in development may not be sufficient to support regulatory approval, or regulatorscould interpret the data differently and less favorably than we do. Further, the design of a clinical trial can determine whether its results will support approvalof a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Clinical trials of potential productsoften reveal that it is not practical or feasible to continue development efforts. Regulatory authorities may require us or our partners to conduct additionalclinical testing, in which case we would have to expend additional time and resources. The approval process may also be delayed by changes in governmentregulation, future legislation or administrative action or changes in regulatory policy that occur prior to or during regulatory review. The failure to provideclinical and preclinical data that are adequate to demonstrate to the satisfaction of the regulatory authorities that our agents in development are safe andeffective for their proposed use will delay or preclude approval 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 agreements are not binding on the FDA and we can give no assurancesthat the FDA will abide by the terms of our SPA agreement. We also cannot assure any particular 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 an NDA approval, that only one additional clinical trial will have to be conductedprior to filing an NDA, or that flurpiridaz F 18 will ever be approved as a PET MPI imaging agent by the FDA. See Part I, Item 1. “Business—RegulatoryMatters—Food and Drug Laws.”We are not permitted to market our agents in development in the U.S. or other countries until we have received requisite regulatory approvals. Forexample, 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 U.S. also have requirements for approval of agents with which we must comply prior to marketing. Obtaining regulatory approval formarketing 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 in obtainingregulatory approval in one country may have a negative effect on the regulatory process in other countries. Also, any regulatory approval of any of ourproducts 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 indevelopment proceed successfully through clinical trials and receive regulatory approval, there is no guarantee that an approved product can bemanufactured in commercial quantities at a reasonable cost or that such a product will be successfully marketed or distributed. The burden associated withthe marketing and distributing of products like ours is substantial. For example, rather than being manufactured at our own facilities, flurpiridaz F 18 wouldrequire the creation of a complex, field-based network involving PET cyclotrons located at radiopharmacies where the agent would need to be manufacturedand distributed rapidly to end-users, given the agent’s 110-minute half-life. In addition, in the case of flurpiridaz F 18, obtaining adequate reimbursement iscritical, including not only coverage from Medicare, Medicaid, other government payors as well as private payors but 42Table of Contentsalso appropriate payment levels which adequately cover the substantially higher manufacturing and distribution costs associated with a PET MPI agent incomparison to, for example, sestamibi.We may 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 fund our important R&D programs, reducing our internal R&D resources. OnFebruary 21, 2017, we announced entering into a term sheet with GE Healthcare related to the continued development and commercialization of flurpiridaz F18. Subject to satisfactory due diligence and necessary approvals, we anticipate entering into a definitive agreement for the proposed transaction in thesecond quarter of 2017. However, there is no assurance that we will enter into a definitive agreement with GE Healthcare on the proposed terms or at all. SeePart I, Item 1. “Business—Research and Development—Proposed GE Healthcare Transaction”.In the future, we may also seek to engage strategic partners for our 18F LMI 1195 and LMI 1174 programs. However, different strategic partners mayhave different time horizons, risk profiles, return expectations and amounts of capital to deploy, and we may not be able to negotiate relationships withpotential strategic partners on acceptable terms, or at all. If we are unable to establish or maintain these strategic partnerships, we may have to limit the size orscope of, or delay, our development programs.In 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.Our 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 our relationshipswith 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; 43Table of Contents • 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.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 U.S.) issued an alert on the radiation risks of diagnostic imaging and recommendedspecific actions for providing “the right test and the right dose through effective processes, safe technology and a culture of safety.” Revised accreditationstandards 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 44Table of Contentsdate, claims that could be brought against us might not be covered by our insurance policies. Furthermore, although we currently have product liabilityinsurance coverage with policy limits that we believe are customary for pharmaceutical companies in the diagnostic medical imaging industry and adequateto provide us with insurance coverage for foreseeable risks, even where the claim is covered by our insurance, our insurance coverage might be inadequateand we would have to pay the amount of any settlement or judgment that is in excess of our policy limits. We may not be able to obtain insurance on termsacceptable to us or at all, since insurance varies in cost and can be difficult to obtain. Our failure to maintain adequate insurance coverage or successfullydefend against product liability claims could have a material adverse effect on our business, results of operations, 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 U.S. and in foreign countries. Wewill only be able to protect our intellectual property from unauthorized use by third parties to the extent that we maintain the secrecy of our trade secrets andcan 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 U.S. or othercountries may diminish the value of our intellectual property and we may not receive the same degree of protection in every jurisdiction. 45Table of ContentsAccordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third party patents.The 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, andwe could 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 U.S. patents and so our products may not receive the samedegree of protection in foreign countries as they would in the U.S.; • 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. ornon-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 46Table of Contentsour confidential information to competitors or other third parties. Enforcing a claim that a third party improperly obtained and is using our trade secrets isexpensive and time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. are sometimes less willing to protect trade secrets.Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. We often rely on confidentiality agreements with ourcollaborators, employees, consultants and other third parties and invention assignment agreements with our employees to protect our trade secrets and otherknow-how and proprietary information concerning our business. These confidentiality agreements may not prevent unauthorized disclosure of trade secretsand other know-how and proprietary information, and there can be no guarantee that an employee or an outside party will not make an unauthorizeddisclosure of our trade secrets, other technical know-how or proprietary information, or that we can detect such an unauthorized disclosure. We may not haveadequate remedies for any unauthorized disclosure. This might happen intentionally or inadvertently. It is possible that a competitor will make use of thatinformation, and that our competitive position will be compromised, in spite of any legal action we might take against persons making those unauthorizeddisclosures, which could have 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, Quadramet and Lantheus Medical Imaging. We cannotassure you that any pending trademark applications will be approved. Third parties may also oppose our trademark applications, or otherwise challenge ouruse of the trademarks. If our trademarks are successfully challenged, we could be forced to rebrand our products, which could result in loss of brandrecognition, 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 U.S. and inflationary pressures. We cannot anticipate all the ways inwhich the current economic climate and financial market conditions could adversely impact our business. 47Table of ContentsWe 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 healthcare services and pharmaceuticals. If fewer patients are seeking medical care because they do not have insurance coverage, ourcustomers may experience reductions in revenues, profitability and/or cash flow that could lead them to modify, delay or cancel orders for our products. Ifcustomers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of,accounts receivable that are owed to us. This, in turn, could adversely affect our financial condition and liquidity. To the extent prevailing economicconditions result in 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, 2016, 2015 and 2014, we derived approximately 15%, 20% and 22% of our revenues from outside the fifty UnitedStates, respectively. We anticipate that revenue from non-U.S. operations will grow in the future from 2016 levels. Accordingly, our business is subject torisks associated with doing business 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. 48Table 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, 2016, 2015 and 2014, the net impact of foreign currency changes on transactions was a loss of $0.9 million, $1.8 million and $0.3 million,respectively. Operations outside the U.S. 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, including thoseadministered by the U.S. Treasury Department’s Office of Foreign Assets Control, could result in fines, other civil or criminal penalties and the suspension orloss of export privileges which could have a material adverse effect on our business, results of operations, financial conditions and cash flows.With the exception of our United Kingdom subsidiary, the functional currencies of our International Segment subsidiaries are the respective localcurrencies of each entity. Exchange rates between some of these currencies and the U.S. Dollar have fluctuated significantly in recent years and may do so inthe future. Historically, we have not used derivative financial instruments or other financial instruments to hedge against economic exposures related toforeign currencies. During the year ended December 31, 2016, fluctuations in exchange rates had a $0.9 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 U.S. are, either directly or indirectly, with governmental entities, and we could be adversely affectedby violations of the FCPA and similar worldwide anti-bribery laws outside the U.S.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 U.S. are, either directly or indirectly, withgovernmental 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 49Table of Contentsanti-bribery laws may conflict with local customs and practices. Despite our training and compliance programs, our internal control policies and proceduresmay not always protect us from reckless or criminal acts committed by our employees or agents. Violations of these laws, or allegations of those violations,could disrupt our business and result in a material adverse effect on our results of operations, financial condition and 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 which, due to the nature of such attacks, may remain undetected for a period of time. As these threats continue to evolve, wemay be required to expend additional resources to enhance our information security measures or to investigate and remediate any information securityvulnerabilities. Given the extensive reliance of our business on technology, any substantial disruption or resulting loss of data that is not avoided orcorrected by our backup measures could harm our business, reputation, operations and financial condition.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. Our inabilityto retain our existing executive leadership and senior management team, maintain an appropriate internal succession program or attract and retain additionalqualified personnel could have a material adverse effect on our business.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, 2016, we had approximately $284.5 million of total principal indebtedness remaining under our seven-year senior secured termloan facility, which matures on June 30, 2022 (the “Term Facility”). 50Table of ContentsOur aggregate Borrowing Base was approximately $44.6 million, which was reduced by an $8.8 million unfunded Standby Letter of Credit and $0.1 millionin accrued interest, resulting in remaining availability under our Revolving Facility of $35.7 million. Our substantial indebtedness and any futureindebtedness 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; • 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 51Table of Contentsamong restricted subsidiaries and us and indebtedness relating to hedging obligations. See Part II, Item 7. “Management’s Discussion and Analysis ofFinancial Condition and Results of Operations—Liquidity and Capital Resources—External Sources of Liquidity.” If we or our subsidiaries incur additionaldebt, the risks that we and they now face as a result of our high leverage could intensify. In addition, the agreements governing our senior secured creditfacilities will not prevent us from incurring obligations that do not constitute indebtedness 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; • 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, 2016, we had federal income tax loss carryforwards of $200.3 million, which will begin to expire in 2030 and will completelyexpire in 2036. We have had significant financial losses in previous years and as a result we currently maintain a full valuation allowance for our net deferredtax assets including our federal and state tax loss carryforwards. We may be limited in our ability to use these tax loss carryforwards to reduce our future U.S.federal income tax liabilities if we were to experience another “ownership change” as specified in Section 382 of the Internal Revenue Code including if wewere to issue a certain amount of equity securities, certain of our stockholders were to sell shares of our common stock, or we were to enter into certainstrategic transactions.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; 52Table of Contents • Actual or anticipated fluctuations in our quarterly financial and operating 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; • Acquisitions or introductions of new products or services by us or our competitors; • 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.If 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.

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.As of December 31, 2016, we had no material ongoing litigation in which we were a party or any material ongoing regulatory or other proceeding andhad no knowledge of any investigations by governmental or regulatory authorities in which we are a target that could have a material adverse effect on ourcurrent business.Item 4.

Selected Financial DataBasis of Financial InformationThe consolidated financial statements have been prepared in U.S. Dollars, in accordance with accounting principles generally accepted in the UnitedStates of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Holdings and its wholly-owned subsidiaries. Allintercompany accounts and transactions have been eliminated in consolidation.Non-GAAP Financial MeasuresAdjusted EBITDA and EBITDA as used in our equity incentive plans, collectively, our Non-GAAP Measures, as presented in this Annual Report onForm 10-K, are supplemental measures of our performance that are not required by, or presented in accordance with U.S. GAAP. They are not measurements ofour financial performance under U.S. GAAP and should not be considered as alternatives to net income (loss) or any other performance measures derived inaccordance with U.S. GAAP or as alternatives to cash flow from operating activities as measures of our liquidity. 57Table of ContentsOur 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 on Form 10-K because we believe that this information is used by certain investors as measures ofa company’s historical 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. 58Table of ContentsSelected Financial DataIn the table below, we provide you with our selected consolidated financial data for the periods presented.

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.Management believes that the inclusion of the adjustments to EBITDA applied in presenting Adjusted EBITDA are appropriate to provide additionalinformation to investors about the Company’s performance across reporting periods on a consistent basis by excluding items that it does not believeare indicative of its 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 Part II, Item 6. “SelectedFinancial Data” and the consolidated financial statements and the related notes included in Item 8 of this Annual Report on Form 10-K. This discussioncontains forward-looking statements related to future events and our future financial performance that are based on current expectations and subject torisks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors,including those set forth under Part I, Item 1A. “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements.”OverviewOur BusinessWe 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. Clinicians use our imaging agents and products across a range ofimaging modalities, including echocardiography and nuclear imaging. 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 cardiologists, nuclear physicians, radiologists, internal medicine physicians, technologists and sonographersworking in a variety of clinical settings. We sell our products to radiopharmacies, integrated delivery networks, hospitals, clinics and group practices.We sell our products globally and have operations in the U.S., Puerto Rico and Canada and third-party distribution relationships in Europe, Canada,Australia, Asia Pacific and Latin America.Our Product PortfolioOur 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 U.S. 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 in the U.S., itscomposition of matter patent will expire in 2019 and its manufacturing patent in 2021. In numerous foreign jurisdictions, patent protection orregulatory exclusivity will expire in 2019. We also have an active next generation development program for this agent. • TechneLite is a technetium generator which provides the essential nuclear material used by radiopharmacies to radiolabel Cardiolite, Neuroliteand other technetium-based radiopharmaceuticals used in nuclear medicine procedures. TechneLite uses 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 is processed and finished by us.Sales of our contrast agent, DEFINITY, are made in the U.S. and Canada through our direct sales team of 78 employees. In the U.S., our nuclear imagingproducts, including TechneLite, Xenon, Cardiolite and Neurolite, are primarily distributed through commercial radiopharmacies, the majority of which arecontrolled by or associated with Cardinal, UPPI, GE Healthcare and Triad. A small portion of our nuclear imaging product sales in the U.S. are made throughour direct sales force to hospitals and clinics that maintain their own in-house 62Table of Contentsradiopharmaceutical capabilities. Outside the United States, we own one radiopharmacy in Puerto Rico and sell our own products as well as products of thirdparties to end-users. In January 2016, we sold our Canadian radiopharmacies to Isologic and entered into the Isologic Supply Agreement, under which wesupply Isologic with certain of our products on commercial terms, including certain product purchase commitments by Isologic. The Isologic SupplyAgreement expires in January 2021 and may be terminated upon the occurrence of specified events, including a material breach by the other party,bankruptcy by either party or certain force majeure events. In August 2016, we sold our Australian radiopharmacy servicing business to GMS, and enteredinto the GMS Supply Agreement under which we supply GMS with certain of our products on commercial terms, including certain minimum productpurchase commitments by GMS. The GMS Supply Agreement expires in August 2020 and may be terminated in whole or in part on a product-by-productbasis upon the occurrence of specified events, including a material breach by the other party, bankruptcy by either party or certain force majeure events. Wealso maintain our own direct sales force in Canada so we can control the importation, marketing, distribution and sale of our imaging agents in Canada. InEurope, Australia, Asia Pacific and Latin America, we rely on third party distributors to market, sell and distribute our nuclear imaging and contrast agentproducts, either on a country-by-country basis or on a multi-country regional basis.The following table sets forth our revenues derived from our principal products: Year EndedDecember 31, (in thousands) 2016 % ofRevenues 2015 % ofRevenues 2014 % ofRevenues DEFINITY $131,612 43.6% $111,859 38.1% $95,760 31.8% TechneLite 99,217 32.9% 72,562 24.7% 93,588 31.0% Xenon 29,086 9.6% 48,898 16.7% 36,549 12.1% Other 41,938 13.9% 60,142 20.5% 75,703 25.1% Total revenues $301,853 100.0% $293,461 100.0% $301,600 100.0% 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.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 to continue to manufacture and release DEFINITY on a timely andconsistent basis. See Part I, Item 1A. “Risk Factors—The growth of our business is substantially dependent on increased market penetration for theappropriate use of DEFINITY in suboptimal echocardiograms.”There are three echocardiography contrast agents approved by the FDA for sale in the U.S.—DEFINITY which we estimated to have, as of December 31,2016, an approximately 80% share of the U.S. market for contrast agents in echocardiography procedures, Optison from GE Healthcare, and Lumason fromBracco.Competition for XenonXenon gas for lung ventilation diagnosis is our third largest product by revenues. Historically, several companies, including IBAM, sold packagedXenon as a pulmonary imaging agent in the U.S., but from 2010 63Table of Contentsthrough the first quarter of 2016, we were the only supplier of this imaging agent in the U.S. In March 2016, IBAM received regulatory approval from theFDA to again sell packaged Xenon in the U.S. and has begun to do so. Depending upon the pricing, extent of availability and market penetration of IBAM’soffering, we believe we are at risk for volume loss and price erosion for those customers which are not subject to price or volume commitments with us. Inorder to increase the predictability of our Xenon business, we have entered into Xenon supply agreements at committed volumes and reduced prices withcontracted customers. These steps have resulted in predictable Xenon unit volumes in 2016, but with sales at substantially lower revenue and gross margincontributions as compared to 2015. See Part I, Item 1A. “Risk Factors—We face potential supply and demand challenges for Xenon.”Global Isotope SupplyHistorically, an important supplier of Moly and Xenon was Nordion, which relied on the NRU reactor in Chalk River, Ontario. For Moly and Xenon, wehad supply agreements with Nordion that expired on October 31, 2016. We currently have Moly supply agreements with NTP of South Africa, ANSTO ofAustralia, and IRE of Belgium, each running through December 31, 2017 and a Xenon supply agreement with IRE which runs through June 30, 2019, subjectto extensions.We believe we are well-positioned with ANSTO, IRE and NTP to have a secure supply of Moly, including LEU Moly. From November 2016, the NRUreactor transitioned from providing regular supply of medical isotopes to providing only emergency back-up supply of HEU based Moly through March2018. ANSTO has already significantly increased its Moly production capacity from its existing facility in August 2016 and has under construction, incooperation with NTP, a new Moly processing facility that ANSTO believes will expand its production capacity up to approximately 3,500 six-daycuries/week, which is expected to be in commercial operation in the first half of 2018. In addition, IRE received approval from its regulator to expand itsproduction capability by up to 50% of its former capacity. The new ANSTO and IRE production capacity is expected to replace and exceed what was theNRU’s most recent routine production.We are also now receiving bulk unprocessed Xenon from IRE, which we are processing and finishing for our customers. We believe we are well-positioned to supply Xenon to our customers. See Part I, Item 1A. “Risk Factors—We face potential supply and demand challenges for Xenon.”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 our sole source manufacturer of DEFINITY, Neurolite, Cardiolite and evacuation vials, the latterbeing an ancillary component for our TechneLite generators. We are currently seeking approval for JHS manufacturing certain of our products from certainforeign regulatory authorities. Until we receive these approvals, we will face continued limitations on where we can sell those products outside of the U.S.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. Our technology transfer activities with Pharmalucence for the manufacture and supply of DEFINITY have been repeatedly delayed,and we are now in the process of negotiating an exit to that arrangement. We currently have additional on-going technology transfer activities for our nextgeneration DEFINITY product with SBL, but we cannot give any assurances as to when that technology transfer will be completed and when we will actuallyreceive supply of next generation DEFINITY product from SBL. See Part I, Item IA. “Risk Factors—Our dependence upon third parties for the manufactureand supply of a substantial portion of our products could prevent us from delivering our products to our customers in the required quantities, within therequired timeframes, or at all, which could result in order cancellations and decreased revenues.” 64Table of ContentsRadiopharmaceuticals 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 TechneLiteWe believe there was a decline in the MPI study market due to industry-wide cost containment initiatives that have resulted in a transition of whereimaging procedures are performed, from free-standing imaging centers to the hospital setting. The total MPI market has been essentially flat for the period2011 through 2015. Our 2016 sales of TechneLite generators exceeded our expectations because of opportunistic sales when customers could not obtainsufficient generators from other suppliers. We can give no assurances that such opportunistic sales will be replicated in 2017.In November 2016, CMS announced the 2017 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% LEU. In January 2013, we began to offer a TechneLite generator which containsMoly sourced from at least 95% LEU and which satisfies the requirements for reimbursement under this incentive program. Although demand for LEUgenerators appears to be growing, we do not know when, or if, this incremental reimbursement for LEU Moly generators will result in a material increase inour generator sales.Nuclear Contracting Strategy—CardinalHistorically, Cardinal has been our largest customer for radiopharmaceutical agents and products. Our written supply agreements with Cardinal relatingto TechneLite, Xenon, Neurolite, Cardiolite and certain other products expired in accordance with their terms on December 31, 2014. Following extendeddiscussions with Cardinal, on November 19, 2015, we entered into a new contract for the distribution of TechneLite, Xenon, Neurolite and other productsbeginning in 2015 through December 2017. The agreement specifies pricing levels and requirements to purchase minimum shares of certain products duringcertain periods. From January 1, 2015 until the signing of the new agreement on November 19, 2015, we continued to accept and fulfill product orders fromthis major customer on a purchase order basis at supply prices.In connection with increased sales volumes and a broader mix of products sold to Cardinal at lower contracted pricing than the pricing in effect formost of 2015, our 2016 results reflect higher revenues but lower gross margins than in most of 2015. We expect that our 2017 revenues from Cardinal willincrease versus 2016 because of higher share commitments from Cardinal for certain products.Research 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 fund our important R&D programs, reducing our internal R&D resources. On February 21, 2017 we announced entering into a termsheet with GE Healthcare relating to the continued development and worldwide commercialization of flurpiridaz F 18. In the future, we may also seek toengage strategic partners for our 18F LMI 1195 and LMI 1174 programs. See Part I, Item 1. “Business—Research and Development—Proposed GE HealthcareTransaction”; Part I, Item 1A. “Risk Factors—We may not be able to further develop or commercialize our agents in development without successful strategicpartners.”SegmentsWe report our results of operations in two operating segments: U.S. and International.

Offsetting these increases was a $19.8 million decrease in Xenon revenues primarily as a result of contracts withsignificant customers that reduced unit pricing in exchange for committed volume purchases and a $1.7 million decrease in Ablavar as the product is nolonger sold.The decrease in the International segment revenues during the year ended December 31, 2016, as compared to the prior year period, is primarily theresult of the decreases in revenues in Canada and Australia attributable to the sale of our radiopharmacy businesses.

Offsetting these decreases was an increase of$15.8 million in DEFINITY revenues driven primarily by higher unit volumes and an increase of $12.3 million in Xenon revenues primarily as a result ofhigher selling prices.The decrease in the International segment revenues during the year ended December 31, 2015, as compared to the prior year period, is primarily due to$6.8 million unfavorable foreign exchange and $2.2 million decrease in Cardiolite revenues as a result of competitive pressures. This was offset, in part, by$0.6 million in DEFINITY 67Table of Contentsrevenues driven by increased volume, $0.6 million increase in TechneLite revenues driven by volumes and $0.3 million in other marketed products.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 and allowances result from performance-based offers that are primarily based on attaining contractually specifiedsales volumes and growth, Medicaid rebate programs for our products, administrative fees of group purchasing organizations, royalties and certain distributorrelated commissions. The calculation of the accrual for these rebates and allowances is based on an estimate of the third party’s buying patterns and theresulting applicable 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 andAllowances Balance, as of January 1, 2014 $1,739 Current provisions relating to revenues in current year 5,773 Adjustments relating to prior years’ estimate (18) Payments/credits relating to revenues in current year (4,264) Payments/credits relating to revenues in prior years (1,066) Balance, as of December 31, 2014 2,164 Current provisions relating to revenues in current year 6,413 Adjustments relating to prior years’ estimate (84) Payments/credits relating to revenues in current year (4,784) Payments/credits relating to revenues in prior years (1,406) Balance, as of December 31, 2015 2,303 Current provisions relating to revenues in current year 7,255 Adjustments relating to prior years’ estimate (452) Payments/credits relating to revenues in current year (5,255) Payments/credits relating to revenues in prior years (1,554) Balance, as of December 31, 2016 $ 2,297 Cost of Goods SoldCost of goods sold consists of manufacturing, distribution, intangible asset amortization and other costs related to our commercial products.

Offsetting these increases was a $0.7 million decrease in technology transfer expenses.The decrease in the International segment cost of goods sold during the year ended December 31, 2016 over the prior year period, is primarily due tolower manufacturing costs for certain products as a result of the sale of our Canadian and Australian radiopharmacy businesses.2015 v. 2014The decrease in the U.S. segment cost of goods sold for the year ended December 31, 2015 over the prior year 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, there was a $2.8 million decrease in Neurolite costof 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 tolower unit volumes sold. Offsetting these decreases was a $4.5 million increase in DEFINITY cost of goods due to 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.The increase in the International segment cost of goods sold during the year ended December 31, 2015 over the prior year period is primarily due toapproximately $5.8 million in product cost pricing increases.

Our provisionfor income taxes results primarily from taxes due in certain foreign jurisdictions where we generate taxable income, as well as interest and penaltiesassociated with uncertain tax positions, offset by reversals of those positions as statutes lapse or are settled during the year. Book income before taxes wasrelatively close to zero in 2014 and 2015, and increased significantly in 2016. Accordingly, fluctuations in our effective tax rates during these years may notbe overly meaningful nor indicative of on-going trends.Our effective tax rates for the periods presented are as follows: Year EndedDecember 31, 2016 2015 2014 Effective tax rate 5.4% 25.2% 50.5% 73Table of ContentsLiquidity and Capital ResourcesCash FlowsThe following table provides information regarding our cash flows: Year EndedDecember 31, (in thousands) 2016 2015 2014 Cash provided by operating activities $49,642 $21,762 $11,590 Cash provided by (used in) investing activities $3,281 $(13,151) $(7,682) Cash (used in) provided by financing activities $(30,217) $999 $(2,297) Effect of foreign exchange rates on cash and cash equivalents $(124) $(753) $(450) Net Cash Provided by Operating ActivitiesCash provided by operating activities of $49.6 million for the year ended December 31, 2016 was driven primarily by net income of $26.8 million plus$19.9 million of depreciation, amortization and accretion expense and $1.9 million of debt retirement costs offset by the gain on sale of assets of$6.4 million. In addition, our increase in cash from working capital during the year ended December 31, 2016, was driven primarily by an increase of$5.7 million in accounts payable due to the timing of payment runs and a $1.3 million increase in accrued expenses primarily due to an increase in accruedbonus, offset by a $3.6 million increase in inventory due to the timing of receipt of lots and a $1.0 million increase in accounts receivable due to increasedsales.Cash provided by operating activities of $21.8 million for the year ended December 31, 2015 was driven primarily by a net loss of $14.7 million,which was offset by $22.1 million of depreciation, amortization, and accretion expense and $15.5 million loss on extinguishment of debt. These net sourcesof cash were offset by a decrease in cash from working capital. Our working capital decrease was driven primarily by a $4.0 million decrease in accruedexpenses as a result of less interest following the debt refinancing in June 2015, a $1.7 million decrease in accounts payable due to the timing of paymentruns and a $2.6 million increase in inventory due to timing of production and receipt of inventory.Cash provided by operating activities of $11.6 million for the year ended December 31, 2014 was primarily driven by a net loss of $3.6 million, whichwas offset by $21.7 million of depreciation, amortization and accretion expense and a $2.4 million write-off of deferred offering and financing costs. Thesenet sources of cash were offset by a decrease in cash from working capital. Our working capital decrease was driven primarily by a $4.9 million decrease inaccrued expenses and other liabilities as a result of amortization of deferred revenue, a $4.0 million decrease in accounts payable, and a $3.6 million increasein accounts receivable due to increased revenues. Partially offsetting these was a $1.5 million decrease in inventory as a result of timing of production andreceipt.Net Cash Used in Investing ActivitiesNet cash provided by investing activities in 2016 was primarily due to cash proceeds of $10.6 million received for the sales of our Canadian andAustralian radiopharmacy businesses, which was offset by $7.4 million in capital expenditures.Net cash used in investing activities in 2015 and 2014 reflected the purchase of property and equipment for $13.1 million and $8.1 million,respectively.Net Cash (Used in) Provided by Financing ActivitiesDuring the year ended December 31, 2016, we completed two follow-on underwritten offerings, raising $39.9 million of net proceeds to us from thefirst and $8.9 million of net proceeds to us from the second. We used the net proceeds to us from the first follow-on underwritten offering and cash on hand of$15.1 million to prepay 74Table of Contents$55.0 million of the principal balance of our Term Facility. We used the net proceeds to us from the second follow-on underwritten offering and cash on handof $11.1 million to prepay $20.0 million of the principal balance of our Term Facility. Additionally, we paid approximately $3.7 million for our quarterlyTerm Facility payments. As a result of these debt prepayments, we expect to reduce our annual interest expense by approximately $5.3 million for the yearending December 31, 2017 as compared to 2016.During 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.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. 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.As noted above, in September 2016, we completed a follow-on underwritten offering of 5,200,000 shares of common stock and utilized the netproceeds to us from this offering, combined with cash on hand, to prepay $55.0 million of the principal balance of our Term Facility. In November 2016, wecompleted a second follow-on underwritten offering that included 1,000,000 shares of common stock offered by us and utilized the net proceeds to us fromthis offering, combined with cash on hand, to prepay $20.0 million of the principal balance of our Term Facility. As of December 31, 2016, the principalbalance outstanding on our Term Facility was $284.5 million.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, 2016, 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. 75Table of ContentsOur 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 RatioQ2 2016 to Q4 2016 6.00 to 1.00Q1 2017 to Q2 2017 5.50 to 1.00Thereafter 5.00 to 1.00The 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.As of December 31, 2016, 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 in February 2017. It automatically renewed for aone-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 within 60days 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, 2016, the aggregate Borrowing Base wasapproximately $44.6 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 $35.7 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.Our Revolving Facility also contains customary default provisions as well as cash dominion provisions which allow the lender to sweep our accountsduring the period (x) certain specified events of default are continuing under our Revolving Facility or (y) excess availability under our Revolving Facilityfalls 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 consecutiveBusiness Days or (ii) $5.0 million. During a covenant trigger period, we are required to comply with a consolidated fixed charge coverage ratio of not lessthan 1.00:1.00. The fixed charge coverage 76Table of Contentsratio is calculated on a consolidated basis for Lantheus Holdings and its subsidiaries for a trailing four-fiscal quarter period basis, as (i) EBITDA (as defined inthe agreement) minus capital expenditures minus certain restricted payments divided by (ii) interest plus taxes paid or payable in cash plus certain restrictedpayments 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; • 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 Part I, Item 1A. “Risk Factors—We may not be able to generate sufficient cash flow to meet our debt service obligations.” 77Table of ContentsIf 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, 2016, our only current committed external source of funds is our borrowing availability under our Revolving Facility. We generated anet income of $26.8 million during the year ended December 31, 2016 and had $51.2 million of cash and cash equivalents at December 31, 2016.Availability under our Revolving Facility is calculated by reference to the Borrowing Base. If we are not successful in achieving our forecasted results, ouraccounts receivable and inventory could be negatively affected, reducing the Borrowing Base and limiting our borrowing availability. Our Term Facilitycontains a number of affirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds.Incremental borrowings under the Revolving Facility may affect our ability to comply with the covenants in the Term Facility, including the financialcovenant restricting 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 the foreseeable future.Contractual 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, 2016: Payments Due by Period (in thousands) Total Less than1 Year 1 - 3 Years 3 -5 Years More than5 Years Debt obligations (principal) $284,525 $3,650 $7,300 $7,300 $266,275 Interest on debt obligations(1) 105,853 19,821 38,875 37,853 9,304 Operating lease obligations(2) 1,840 251 471 471 647 Purchase obligations 9,743 4,460 5,283 — — Capital lease obligations 392 124 247 21 — Other long-term liabilities(3) — — — — — Asset retirement obligations(4) — — — — — Total contractual obligations $402,353 $28,306 $52,176 $45,645 $276,226 (1)Amount relates to the minimum interest under the Term Facility.(2)Operating leases include minimum payments under leases for our facilities and certain equipment.(3)Our other long-term liabilities in the consolidated balance sheet include unrecognized tax benefits and related interest and penalties. As ofDecember 31, 2016, we had unrecognized tax benefits of $33.2 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. 78Table of Contents(4)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, 2016, the liability, which was approximately $9.4 million, was measured at thepresent value of the obligation expected to be incurred, of approximately $26.9 million.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 effecton our financial condition, results of operations and cash flows.Recent Accounting StandardsRefer to Footnote 2, “Summary of Significant Accounting Policies,” in the accompanying consolidated financial statements located under Item 8 ofthis Annual Report on Form 10-K for information regarding recently issued accounting standards that may have a significant impact on our business.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 distributors, radiopharmacies and directly to hospitals and clinics. Werecognize revenue when evidence of an arrangement exists, title has passed, substantially all 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 that point in time 79Table of Contentswhen criteria are met and revenue can be recognized. Revenue is recognized net of reserves, which consist of allowances for returns and rebates. The estimatesof these allowances are based on historical sales volumes and mix and require assumptions and judgments to be made in order to make those estimates. In theevent that the sales mix is different from our estimates, we may be required to pay higher or lower returns and sales rebates than we previously estimated. Anychanges to these estimates are recorded in the current period. In 2016, 2015 and 2014, these changes in estimates were not material to our results.InventoryInventory includes 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. All goodwill has beenallocated to the U.S. reporting unit.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 2016 anddetermined that the fair value of our reporting unit was substantially in excess of its carrying value.We calculate the fair value of our reporting unit using the income approach and the market approach using level 3 inputs. The income approachutilizes discounted forecasted future cash flows and the market approach utilizes fair value multiples of comparable publicly traded companies. Thediscounted cash flows are based on our most recent long-term financial projections and are discounted using a risk adjusted rate of return, which isdetermined using estimates of market participant risk-adjusted weighted-average costs of capital and reflects the risks associated with achieving future cashflows. The market approach is calculated using the guideline company method, where we use market multiples derived from stock prices of companiesengaged in the same or similar lines of business. There is not a quoted market price for our reporting unit, therefore, a combination of the 80Table of Contentstwo methods is utilized to derive the fair value of the business. We evaluate and weigh the results of these approaches as well as ensure we understand thebasis of the results of these two methodologies. We believe the use of these two methodologies ensures a consistent and supportable method of determiningour fair value that is consistent with the objective of measuring fair value. If the fair value were to decline, then we may be required to incur material chargesrelating 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.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.Income 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 such 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 prudent and feasible tax planning strategies. Adjustments to thedeferred tax valuation allowances are made in the period when those assessments are made.In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence,and weighted the evidence based on its objectivity. Evidence the Company considered included its history of net operating losses, which resulted in theCompany recording a full valuation allowance for domestic deferred tax assets in 2011 and each year thereafter. The Company was profitable on acumulative basis for the three years ended December 31, 2016, but substantially all of the profitability during that period was achieved during 2016.The Company continues to evaluate other negative evidence including customer concentration and contractual risk, the risk of moly supplyavailability and cost, DEFINITY supplier risk, and certain product development risks, all of which provide for uncertainties around the Company’s futurelevel of profitability. Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability andthe objectively verifiable negative evidence outweighed the positive evidence and it has continued to record a valuation allowance to reduce its deferred taxassets to the amount that is more likely than not to be realizable as of December 31, 2016. The Company will continue to assess the level of the valuation 81Table of Contentsallowance required. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release wouldlikely have a material impact on the Company’s results of operations.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 statements 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 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 and have not historically used derivative financial instruments or other financial instruments to hedge theseeconomic exposures.Interest Rate RiskAs a result of our Term Facility, we have substantial variable rate debt. Fluctuations in interest rates may affect our business, financial condition, resultsof operations and cash flows. As of December 31, 2016, we had $284.5 million outstanding principal 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 impact our future earnings and cash flows. As of December 31, 2016, there was an$8.8 million unfunded Standby Letter of Credit and $0.1 million accrued interest, which reduced availability to $35.7 million on the Revolving Facility.Any increase in the interest rate under the Revolving Facility may have a negative impact on our future earnings to the extent we have outstandingborrowings under the Revolving Facility. The effect of a 100 basis points adverse change in market interest rates, in excess of applicable minimum floors, onour interest expense would be approximately $3.4 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. 82Table of ContentsDuring years ended December 31, 2016, 2015 and 2014, the net impact of foreign currency changes on transactions was a loss of $0.9 million,$1.8 million and $0.3 million, respectively. Historically, we have not used derivative financial instruments or other financial instruments to hedge theseeconomic exposures.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. If the U.S. Dollar had been uniformly stronger by 10%, compared to the actual averageexchange rates, our gross margin would have decreased by $1.8 million during the year ended December 31, 2016.The cost of goods for our products that are manufactured in the U.S. are sold in currencies other than the U.S. Dollar by our foreign subsidiaries are alsoaffected by foreign currency exchange rate movements. Our gross margin would have decreased by $1.4 million if the U.S. Dollar had been stronger by 10%when compared to the actual rates used during the twelve months ended December 31, 2016 as a result of this risk. 83Table of ContentsItem 8.

These financial statements are the responsibility of the Company’s management. Our responsibility is to express anopinion on these financial statements based on our audits.We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standardsrequire that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. TheCompany is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included considerationof internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose ofexpressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An auditalso includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principlesused and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide areasonable basis for our opinion.In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Lantheus

Description of BusinessHoldings, a Delaware corporation, is the parent company of Lantheus Medical Imaging, Inc. (“LMI”), also a Delaware corporation.The Company develops, manufactures and commercializes innovative diagnostic medical imaging agents and other products that assist clinicians inthe diagnosis and treatment of cardiovascular and other diseases. The Company’s commercial products are used by cardiologists, nuclear physicians,radiologists, internal medicine physicians, sonographers and technologists working in a variety of clinical settings. The Company sells its products toradiopharmacies, integrated delivery networks, hospitals, clinics and group practices. The Company sells its products globally and has operations in the U.S.,Puerto Rico and Canada and third-party distribution relationships in Europe, Canada, Australia, Asia Pacific and Latin America.The Company has a portfolio of nine commercial products, which are diversified across a range of imaging modalities. The Company’s imaging agentsinclude an ultrasound contrast agent 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 U.S., is indicated for use in patients withsuboptimal echocardiograms to assist in the visualization of the left ventricle, the main pumping chamber of the heart. The use of DEFINITY inechocardiography 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 (“Xenon”) is a radiopharmaceutical gas that is inhaled and used to assess pulmonary function and also cerebral blood flow. • Neurolite is an injectable, technetium-labeled imaging agent used with Single Photon Emission Computed Tomography (“SPECT”) technologyto identify the area within the brain where blood flow has been blocked or reduced due to stroke. • Cardiolite is an injectable, technetium-labeled imaging agent, also known by its generic name sestamibi, used with SPECT technology inmyocardial perfusion imaging (“MPI”), procedures that assess blood flow distribution to the heart.In the U.S., the Company sells DEFINITY through its direct 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 through third-partycommercial radiopharmacies.The Company’s International operations consist of sales directly to end users through its wholly-owned radiopharmacy in Puerto Rico and salesthrough the Company’s distributors in Canada, Europe, Australia, Asia Pacific and Latin America.2. Summary of Significant Accounting PoliciesBasis of Presentation and Principles of ConsolidationThe accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the UnitedStates of America (“U.S. GAAP”). The consolidated financial 91Table of Contentsstatements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated inconsolidation.ReclassificationsCertain reclassifications have been made to conform the prior year consolidated financial statements and notes to the current year presentation. Thesereclassifications include: • During the first quarter of 2016, the Company early adopted ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification ofDeferred Taxes on a retrospective basis. This standard requires all deferred taxes and liabilities, and any related valuation allowances, to beclassified as non-current on the balance sheet. The adoption of this standard resulted in the reclassification of $0.1 million of current deferred taxassets to noncurrent deferred tax assets and $0.2 million of current deferred tax liabilities to noncurrent deferred tax liabilities on theconsolidated balance sheet at December 31, 2015. • Reclassification of $9.1 million of computer software, net to property, plant & equipment, net in the consolidated balance sheet at December 31,2015.Initial Public OfferingOn June 25, 2015, in conjunction with its initial public offering (“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.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 istraded on the NASDAQ Global Market under the symbol “LNTH”. The Company issued and sold 12,256,577 shares of common stock in the IPO, including1,423,243 shares that were offered and sold pursuant to the underwriters’ exercise in full of their overallotment option. The IPO resulted in proceeds to theCompany of approximately $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 (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 (the “Senior Notes”), pay related premiums, interest and expenses and pay down the $8.0 million ofoutstanding borrowings under LMI’s $50.0 million revolving credit facility (the “Revolving Facility”).Manufacturing and Customer Concentrations, Liquidity and Management’s PlansThe Company currently relies on Jubilant HollisterStier (“JHS”) as its sole source manufacturer of DEFINITY, Neurolite and evacuation vials forTechneLite. The Company recently completed its technology transfer activities at JHS and received Food and Drug Administration (“FDA”) approval for itsCardiolite product supply. The Company’s technology transfer activities with Pharmalucence for the manufacture and supply of DEFINITY have beenrepeatedly delayed, and the Company is now in the process of negotiating an exit to that arrangement. The Company currently has additional on-goingtechnology transfer activities for its next generation DEFINITY product with Samsung BioLogics (“SBL”) but can give no assurances as to when thattechnology transfer will be completed and when the Company will actually receive supply of next generation DEFINITY product from SBL.Until the Company successfully becomes dual sourced for its principal products, the Company is vulnerable to future supply shortages. Disruption inthe Company’s financial performance could occur if it experiences significant adverse changes in customer mix, broad economic downturns, adverse industryor Company 92Table of Contentsconditions or catastrophic external events. If the Company experiences one or more of these events in the future, it may be required to implement additionalexpense reductions, such as a delay or elimination of discretionary spending in all functional areas, as well as scaling back select operating and strategicinitiatives.During 2014, the Company utilized its Revolving Facility as a source of liquidity from time to time. Borrowing capacity under the Revolving Facilityis calculated by reference to a borrowing base consisting of a percentage of certain eligible accounts receivable, inventory and machinery and equipmentminus any reserves (the “Borrowing Base”). If the Company is not successful in achieving its forecasted operating results, the Company’s accounts receivableand inventory could be negatively affected, thus reducing the Borrowing Base and limiting the Company’s borrowing capacity. As of December 31, 2016,the aggregate Borrowing Base was approximately $44.6 million, which was reduced by an $8.8 million unfunded Standby Letter of Credit and $0.1 millionin accrued interest, resulting in a net Borrowing Base availability of approximately $35.7 million. The Company’s Term Facility contains a number ofaffirmative, negative, reporting and financial covenants, in each case subject to certain exceptions and materiality thresholds. Incremental borrowings underthe Revolving Facility may affect the Company’s ability to comply with the covenants in the Term Facility, including the financial covenant restricting totalnet 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, cash generated by operating activitiesand availability under the Revolving Facility will be sufficient to continue to fund the Company’s liquidity requirements for the foreseeable future.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, but are notlimited to, certain judgments regarding revenue recognition, goodwill, tangible and intangible asset valuation, inventory valuation, asset retirementobligations, income tax liabilities and related indemnification receivable, deferred tax assets and liabilities and accrued expenses. Actual results couldmaterially differ from those estimates or assumptions.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 all revenue recognition criteria havenot yet been met, the respective amounts are recorded as deferred revenue until such point in time all criteria have been met and revenue can be recognized.Revenue is recognized net of reserves, which consist of allowances for returns and rebates.Revenue 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 future 93Table of Contentsproducts 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 approximated actual returns.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 $13.6 million, $17.4 million and $19.4 million for the yearsended December 31, 2016, 2015 and 2014, respectively.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 the Company becomes aware of any specific collection issues.Also included in accounts receivable are miscellaneous receivables of $0.7 million and $1.0 million as of December 31, 2016 and 2015, respectively.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.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 liabilities. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effectfor the years in which those tax attributes are expected to be recovered or paid, and are adjusted for changes in tax rates and tax laws when such changes areenacted.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 94Table of Contentsweighing of both positive and negative evidence concerning both historical and prospective information with greater weight given to evidence that isobjectively verifiable. A history of recent losses is negative evidence that is difficult to overcome with positive evidence. In evaluating prospectiveinformation there are four sources of taxable income: reversals of taxable temporary differences, items that can be carried back to prior tax years (such as netoperating losses), pre-tax income, and prudent and feasible tax planning strategies. Adjustments to the deferred tax valuation allowances are made in theperiod 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.Net Income (Loss) per Common ShareBasic earnings per common 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 common share is calculated by dividing the net loss by the weighted-average shares of commonstock outstanding and potentially dilutive 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.Concentration 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.The following table sets forth customers that contributed revenues of 10% or more during any of the years ended December 31, 2016, 2015 and 2014and/or represented 10% or more of the total net accounts receivable balance at either December 31, 2016 or 2015: AccountsReceivableDecember 31, RevenuesYear EndedDecember 31, 2016 2015 2016 2015 2014 Company A *** *** 10.3% 11.3% 18.0% Company B 13.1% 12.9% 11.4% 11.9% 11.1% ***Amount represented less than 10% for the reporting periodThe Company relies on certain materials used in its development and manufacturing processes, some of which are procured from only one or a fewsources. The failure of one of these suppliers to deliver on schedule could delay or interrupt the manufacturing or commercialization process and wouldadversely 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. 95Table of ContentsHistorically, an important supplier of Moly and Xenon was Nordion, which relied on the NRU reactor in Chalk River, Ontario. From November 2016the NRU reactor transitioned from providing regular supply of medical isotopes to providing only an emergency back-up of HEU based Moly through March2018. For Moly and Xenon, the Company had supply agreements with Nordion that expired on October 31, 2016. The Company currently has Moly supplyagreements with NTP Radioisotopes (“NTP”), ANSTO and Institute for Radioelements (“IRE”), each with an expiration date of December 31, 2017 and aXenon supply agreement with IRE which runs through June 30, 2019, subject to extensions. The Company currently relies on IRE as the sole supplier ofbulk-unprocessed Xenon which the Company processes and finishes for its customers.The Company currently relies on JHS as its sole source manufacturer of DEFINITY, Neurolite and evacuation vials for TechneLite. The Companyrecently completed its technology transfer activities at JHS and received FDA approval for its Cardiolite product supply. In the meantime, the Company hasno other currently active supplier of DEFINITY, Neurolite and Cardiolite.Based on current projections, the Company believes that it will have sufficient supply of DEFINITY, Neurolite, Cardiolite and evacuation vials fromJHS to meet expected demand.The following table sets forth revenues for each of the Company’s products representing 10% or more of revenues: Year EndedDecember 31, 2016 2015 2014 DEFINITY 43.6% 38.1% 31.8% TechneLite 32.9% 24.7% 31.0% Xenon *** 16.7% 12.1% ***Amount represented less than 10% for the reporting periodInventoryInventory 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 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 on product shelf life, forecasted demand and other factors.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 as incurred. At December 31, 2016 and 2015, the Company had no capitalized inventories associated with productthat did not have regulatory approval. 96Table of ContentsProperty, Plant & EquipmentProperty, plant & 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. Certain costs to obtain or developcomputer software are capitalized and amortized over the estimated useful life of the software. Depreciation and amortization is computed on a straight-linebasis over the estimated useful lives of the related assets. The estimated useful lives of the major classes of depreciable assets are as follows: Class Range of Estimated Useful LivesBuildings 50 yearsLand improvements 15 - 40 yearsMachinery and equipment 3 - 20 yearsFurniture and fixtures 15 yearsLeasehold improvements Lesser of lease term or 15 yearsComputer software 3-5 yearsUpon retirement or other disposal of property, plant & equipment, the cost and related amount of accumulated depreciation are removed from the assetand accumulated depreciation accounts, respectively. The difference, if any, between the net asset value and the proceeds is included in operating income.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. All goodwillhas been allocated to the U.S. reporting unit.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 2016 and 2015, 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 unit using the income approach and market approach using level 3 inputs. The income approachutilizes discounted forecasted future cash flows and the market approach utilizes fair value multiples of comparable publicly traded companies. Thediscounted cash flows are based on management’s long-term financial projections as of the valuation date and are discounted using a risk adjusted rate ofreturn, which is determined using estimates of market participant risk-adjusted weighted-average costs of capital and reflects the risks associated withachieving future cash flows. The market approach is 97Table of Contentscalculated using the guideline company method, where the Company uses market multiples derived from stock prices of companies engaged in the same orsimilar lines of business. There is not a quoted market price for the Company’s reporting unit, therefore, a combination of the two methods is utilized toderive the fair value of the business. The Company evaluated and weighed the results of these approaches as well as ensures it understands the basis of theresults of these two methodologies. The Company believes the use of these two methodologies ensures a consistent and supportable method of determiningits fair value 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 2016 anddetermined that the fair value of the Company’s reporting unit 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 be impaired, the impairment equalsthe amount by which the carrying amount of the assets exceeds the fair value of the assets. Any impairments are recorded as permanent reductions in thecarrying amount of the assets. Long-lived assets, other than goodwill and other intangible assets that are held for sale are recorded at the lower of the carryingvalue or the fair market value less the estimated cost to sell.During the first quarter of 2013, the Company executed a strategic shift in how it funds its research and development (“R&D”) programs, whichsignificantly altered the expected future costs and revenue associated with the Company’s agents in development. Property, plant & equipment dedicated toR&D activities, which were impacted by the March 2013 R&D strategic shift, have a carrying value of $2.9 million as of December 31, 2016. The Companybelieves these fixed assets will be utilized for either internally funded ongoing R&D activities or R&D activities funded by a strategic partner. If theCompany is not successful in finding a strategic partner, and there are no alternative uses for those fixed assets, they could be subject to impairment in thefuture.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.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 Values of Financial InstrumentsThe estimated fair values of the Company’s financial instruments, including its cash and cash equivalents, accounts receivable, accounts payable andaccrued expenses approximate the carrying values of these instruments due to their short term nature. There are no assets measured at fair value on anonrecurring basis at December 31, 2016. The estimated fair value of the Company’s Term Facility at both December 31, 2016 and 2015 approximatescarrying value because the interest rate is subject to change with market interest rates.Advertising and Promotion CostsAdvertising and promotion costs are expensed as incurred. During the years ended December 31, 2016, 2015 and 2014, the Company incurred$3.6 million, $3.1 million and $2.8 million, respectively in advertising and promotion costs, which are included in sales and marketing in the consolidatedstatements of operations. 98Table of ContentsResearch 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.Foreign CurrencyThe consolidated statements of operations of the Company’s foreign subsidiaries are translated into U.S. Dollars using net weighted average exchangerates. The net assets of the Company’s foreign subsidiaries are translated into U.S. Dollars using the end of period exchange rates. The impact from translatingthe net assets of these subsidiaries at changing rates are recorded in the foreign currency translation adjustment account, which is included in accumulatedother comprehensive loss in the consolidated balance sheets.Remeasurement of the Company’s foreign currency denominated transactions are included in net income. For the years ended December 31, 2016,2015 and 2014, losses arising from foreign currency transactions totaled approximately $0.9 million, $1.8 million and $0.3 million, respectively. Transactiongains and losses are reported as a component of other income (expense), net in the consolidated statements of operations.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 expected volatility based on comparable market participants, expected term of the option, risk-freeinterest rate and expected dividends. When a contingent cash settlement of vested options becomes probable, the Company reclassifies its vested awards to aliability and accounts for any incremental compensation cost in the period in which the settlement becomes probable.Other Income (Expense), NetOther income, net consisted of the following: Years EndedDecember 31, (in thousands) 2016 2015 2014 Foreign currency losses $(853) $(1,752) $(279) Tax indemnification income 1,055 1,655 754 Other income 18 32 30 Total other income (expense), net $220 $(65) $505 Comprehensive Income (Loss)Comprehensive income consists of net income and other gains and losses affecting stockholders’ equity that, under U.S. GAAP, are excluded from netincome. For the Company, such items consist primarily of foreign currency translation gains and losses.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 99Table of Contentsit does business or maintains properties. The Company establishes accruals when those costs are legally obligated and probable and can be reasonablyestimated. Accrual amounts are estimated based on currently available information, regulatory requirements, remediation strategies, historical experience, therelative shares of the total remediation costs and a relevant discount rate, when the time periods of estimated costs can be reasonably predicted. Changes inthese assumptions could impact the Company’s future reported results.Self-Insurance ReservesThe Company’s consolidated balance sheets at both December 31, 2016 and 2015 include $0.4 million of accrued liabilities associated with employeemedical costs that are retained by the Company. The Company estimates the required liability of those claims on an undiscounted basis based upon variousassumptions which include, but are not limited to, the Company’s historical loss experience and projected loss development factors. The required liability isalso subject to adjustment in the future based upon changes in claims experience, including changes in the number of incidents (frequency) and change inthe ultimate cost per incident (severity). The Company also maintains a separate cash account to fund these medical claims and must maintain a minimumbalance as determined by the plan administrator. The balance of this restricted cash account was approximately $0.1 million at both December 31, 2016 and2015, and is included in other current assets.Recent Accounting StandardsThe following table provides a description of recent accounting pronouncements that could have a material effect on the Company’s consolidatedfinancial statements: Standard Description Effective Datefor Company Effect on theConsolidated FinancialStatementsRecently Issued Accounting Standards Not Yet AdoptedASU 2016-15, Statement ofCash Flows (Topic 230):Classification of Certain CashReceipts and Cash Payments This standard addresses the presentation and classification of eight specific cash flow issues,including debt prepayment and extinguishment costs. Early adoption is permitted,including adoption in an interim period. Adoption is required on a retrospective basisunless it is impracticable to apply, in which case the amendments for those issues are to beapplied prospectively as of the earliest date practicable. January 1, 2018 The Company does not expectthe update to havea material impact on itsconsolidated financialstatements.ASU 2016-09, Compensation—Stock Compensation (Topic718): Improvements toEmployee Share-BasedPayment Accounting ASU 2016-09 simplifies several aspects of the stock compensation guidance in Topic 718and other related guidance providing the following amendments: • Accounting for income taxes upon vesting or exercise of share-based payments andrelated EPS effects • Classification of excess tax benefits on the statement of cash flows • Accounting for forfeitures • Liability classification exception for statutory tax withholding requirements • Cash flow presentation of employee taxes paid when an employer withholds sharesfor tax-withholding purposes • Elimination of the indefinite deferral in Topic 718. For public business entities, the amendments are effective for annual periods beginningafter December 15, 2016, and interim periods within those annual periods. January 1, 2017 The Company does not expectthe update to have a materialimpact on its consolidatedfinancial statements.ASU 2016-02, Leases (Topic842) This ASU supersedes existing guidance on accounting for leases in “Leases (Topic 840)”and generally requires all leases to be recognized in the statement of financial position. Theprovisions of ASU 2016-02 are effective for annual reporting periods beginning afterDecember 15, 2018; early adoption is permitted. The provisions of this ASU are to beapplied using a modified retrospective approach. January 1, 2019 The Company is currentlyassessing the impact that thisstandard will have on itsconsolidated financialstatements. 100Table of ContentsStandard Description Effective Datefor Company Effect on theConsolidated FinancialStatementsASU 2014-09, Revenue fromContracts with Customers(Topic 606) and relatedadditional amendments ASU2015-14, ASU 2016-08, ASU2016-10, ASU 2016-11, ASU2016-12 This ASU and related amendments affect any entity that either enters into contracts withcustomers to transfer goods or services or enters into contracts for the transfer ofnonfinancial assets, unless those contracts are within the scope of other standards. Theguidance in this ASU supersedes the revenue recognition requirements in Topic 605,Revenue Recognition and most industry-specific guidance. The core principle of theguidance is that an entity should recognize revenue upon the transfer of promised goods orservices to customers in an amount that reflects the consideration to which the entityexpects to be entitled in exchange for those goods or services. The new guidance alsoincludes a set of disclosure requirements that will provide users of financial statements withcomprehensive information about the nature, amount, timing, and uncertainty of revenueand cash flows arising from a reporting organization’s contracts with customers. In August2015, the Financial Accounting Standards Board issued ASU No. 2015-14, “Revenue fromContracts with Customers (Topic 606): Deferral of the Effective Date,” which defers theeffective date of ASU 2014-09 by one year. This ASU is effective for annual reportingperiods, and interim periods within those years, beginning after December 15, 2017 forpublic companies and permits the use of either the retrospective or cumulative effecttransition method, with early adoption permitted as of annual reporting periods beginningafter December 15, 2016, including interim reporting periods within those annual periods. The standard is effective for annual reporting periods beginning after December 15, 2017,and interim periods therein, using either of the following transition methods: • A full retrospective approach reflecting the application of the standard in each priorreporting period with the option to elect certain practical expedients, or • A retrospective approach with the cumulative effect of initially adopting ASU2014-09 recognized at the date of adoption (which includes additional footnotedisclosures). January 1, 2018 The Company is currentlyevaluating the impact theadoption of ASU 2014-09 on itsconsolidated financialstatements and has not yetdetermined the method bywhich it will adopt the standardin 2018.Accounting Standards Adopted During the Year Ended December 31, 2016ASU 2015-17, Income Taxes(Topic 740): Balance SheetClassification of Deferred Taxes During the first quarter of 2016, the Company early adopted ASU No. 2015-17, IncomeTaxes (Topic 740): Balance Sheet Classification of Deferred Taxes on a retrospective basis.This standard requires all deferred taxes and liabilities, and any related valuationallowances, to be classified as non-current on the balance sheet. January 1, 2016 Adoption of this standardresulted in the reclassification of$0.1 million of current deferredtax assets to noncurrent deferredtax assets and $0.2 million ofcurrent deferred tax liabilities tononcurrent deferred taxliabilities on the accompanyingconsolidated balance sheet atDecember 31, 2015.ASU 2014-15, Presentation ofFinancial Statements—GoingConcern (Subtopic 205-40):Disclosure of Uncertaintiesabout an Entity’s Ability toContinue as a Going Concern This ASU requires management to evaluate whether there are conditions or events thatraise substantial doubt about the entity’s ability to continue as a going concern within oneyear after the date that the financial statements are issued. The ASU is effective for annualreporting periods (including interim reporting periods within those periods) ending afterDecember 15, 2016. December 31, 2016 The adoption of this standarddid not have a material impacton the presentation of theCompany’s consolidatedfinancial statements. 101Table of Contents3. 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 at themeasurement date. • Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilitiesin 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 corroboratedinputs). • 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, 2016 and 2015, the Company’s financial assets that are measured at fair value on a recurring basis are comprised of money marketsecurities and are classified as cash equivalents. The Company invests excess cash from its operating cash accounts in overnight investments and reflectsthese amounts in cash and cash equivalents on the consolidated balance sheet using quoted prices in active markets for identical assets (Level 1).The tables below present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis: December 31, 2016 (in thousands) Total Fair Value (Level 1) (Level 2) (Level 3) Money market $ 3,565 $ 3,565 $ — $ — Total $3,565 $3,565 $— $— 102Table of Contents December 31, 2015 (in thousands) Total FairValue (Level 1) (Level 2) (Level 3) Money market $ 1,586 $ 1,586 $ — $ — Certificates of deposit—restricted 74 — 74 — Total $1,660 $1,586 $74 $— 4.

These amounts are primarily associated with domestic state tax issues, such as the allocation of incomeamong various state tax jurisdictions and transfer pricing.As of December 31, 2016 and 2015, total liabilities for tax obligations and associated interest and penalties were $34.4 million and $33.8 million,respectively, consisting of income tax provisions for uncertain tax benefits of $10.4 million and $11.7 million, interest accruals of $21.9 million and$19.9 million, and penalty accruals of $2.1 million and $2.2 million, respectively. As of December 31, 2016 and 2015, $33.2 million and $32.9 million,respectively, were included in other long-term liabilities on the consolidated balance sheets and $1.2 million and $0.9 million, respectively have reduced theCompany’s deferred tax assets. Included in the 2016, 2015 and 2014 tax provision is $2.0 million, $2.5 million and $1.2 million, respectively, relating tointerest and penalties, net of benefits for reversals of uncertain tax position interest and penalties recognized upon settlements and lapse of statute oflimitations.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 obligation. The tax indemnification receivable is recognized within other noncurrent assets. The total noncurrent asset related to theindemnification was $17.9 million and $17.6 million at December 31, 2016 and 2015, respectively. The changes in the tax indemnification asset arerecognized within other income (expense), net, in the consolidated statement of operations. In accordance with the Company’s accounting policy, the changein the tax liability and penalties and interest associated with these obligations (net of any offsetting federal or state benefit) is recognized within the taxprovision. Accordingly, as these reserves change, adjustments are included in the tax provision while the offsetting adjustment is included in other income(expense), net. Assuming that the receivable from BMS continues to be considered recoverable by the Company, there will be minimal net effect on earningsand net cash outflows related to these liabilities.During the year ended December 31, 2016, 2015 and 2014, BMS, on behalf of the Company, made payments totaling $0.7 million, $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 $1.3 million, $1.6 million and $2.9 million for the year ended December 31, 2016, 2015, and 2014, respectively, which representedthe release of asset balances associated with pre-acquisition years. 105Table of ContentsIncluded in other income (expense), net for the years ended December 31, 2016, 2015 and 2014, is an expense of $0.8 million, $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 andincome of $1.8 million, $2.1 million and $1.9 million at December 31, 2016, 2015 and 2014, respectively, relating to the increase in the indemnificationreceivable for current year interest and penalties.The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significantmanagement judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive andnegative evidence, and weighted the evidence based on its objectivity. Evidence the Company considered included its history of net operating losses, whichresulted in the Company recording a full valuation allowance for domestic deferred tax assets in 2011 and each year thereafter. The Company was profitableon a cumulative basis for the three years ended December 31, 2016, but substantially all of that profitability was achieved during 2016.The Company continues to evaluate other negative evidence including customer concentration and contractual risk, the risk of Moly supplyavailability and cost, DEFINITY supplier risk and certain product development risks, all of which provide for uncertainties around the Company’s futurelevel of profitability. Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability andthe objectively verifiable negative evidence outweighed the positive evidence and it has recorded a valuation allowance to reduce its deferred tax assets tothe amount that is more likely than not to be realizable as of December 31, 2016. The Company will continue to assess the level of the valuation allowancerequired. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release would likely havea material impact on the Company’s results of operations.The following is a reconciliation of the Company’s valuation allowance for the years ended December 31, 2016, 2015, and 2014. (in thousands) Amount Balance at January 1, 2014 $151,339 Charged to provision for income taxes 958 Foreign currency (159) Deductions — Balance at December 31, 2014 152,138 Charged to provision for income taxes 2,704 Foreign currency (590) Deductions — Balance at December 31, 2015 154,252 Charged to provision for income taxes (13,292) Foreign currency (45) Deductions — Balance at December 31, 2016 $140,915 The Company’s U.S. federal income tax returns remain subject to examination for three years. The state and foreign income tax returns remain subjectto examination for periods varying from three to four years depending on the specific jurisdictions’ statute of limitations.At December 31, 2016, the Company has federal net operating loss carryovers of $200.3 million, which will begin to expire in 2030 and completelyexpire in 2036. The Company has state research credits of $1.6 million, which will expire between 2024 and 2031. The Company has Massachusettsinvestment tax credits of approximately $0.4 million, which have no expiration date. 106Table of ContentsThe Company has concluded that an ownership change occurred during 2016, as defined under Section 382 of the Internal Revenue Code. ASection 382 limitation now applies to the Company’s U.S. federal net operating loss carryforwards, as well as its other U.S. tax attributes. The limitation wascomputed based on the value of the Company just prior to the ownership change. It is the Company’s view that its ability to utilize U.S. federal net operatinglosses within the carryforward period is not reduced by the limitation imposed by this ownership change. However, the Company’s U.S. research creditcarryforwards and U.S. foreign tax credit carryforwards will not be utilizable and as such these credits totaling $7.1 million have been removed from the grossdeferred tax asset balances as of December 31, 2016.5. Sales of Certain International Segment AssetsSale of Certain Canadian AssetsDuring the fourth quarter of 2015, the Company committed to a plan to sell certain assets and liabilities associated with the Company’s Canadianoperations in the International Segment. This event qualified for held for sale accounting and the Company determined that the fair value of the net assetsbeing sold significantly exceeded 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 (“Canadian Asset Purchase Agreement”)pursuant to which it would sell substantially all of the assets of its Canadian radiopharmacy businesses and Gludef manufacturing and distribution businessto one of its existing Canadian radiopharmacy customers.The purchase price for the asset sale was $9.0 million in cash and also included a working capital adjustment of $0.5 million, which was settled in thethird quarter of 2016. The Canadian Asset Purchase Agreement contained customary representations, warranties and covenants by each of the parties. Subjectto certain limitations, the buyer will be indemnified for damages resulting from breaches or inaccuracies of the Company’s representations, warranties andcovenants in the Canadian Asset 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 certain of the Company’s products on commercial terms and under which the buyer has agreed tocertain product minimum purchase commitments.The Company does not believe the sale of certain net assets in the international segment constituted a strategic shift that would have a major effect onits operations or financial results. As a result, this transaction is not classified as discontinued operations in the Company’s consolidated financial statementsand the Company has classified the assets and liabilities as held for sale as of December 31, 2015. 107Table of ContentsThe following table summarizes the major classes of assets and liabilities sold as of January 12, 2016 (date of the sale) and held for sale as ofDecember 31, 2015: (in thousands) January 12,2016 December 31,2015 Current Assets: Accounts receivable, net $ 2,620 $ 2,512 Inventory 730 806 Other current assets 15 26 Total current assets 3,365 3,344 Non-Current Assets: Property, plant & equipment, net 760 791 Intangibles, net 462 480 Other long-term assets 28 29 Total assets held for sale $4,615 $4,644 Current Liabilities: Accounts payable $435 $430 Accrued expense and other liabilities 858 1,285 Total liabilities held for sale $1,293 $1,715 This sale of assets resulted in a pre-tax book gain of $5.9 million, which is recorded within gain on sales of assets in the accompanying consolidatedstatements of operations for the year ended December 31, 2016.Sale of Australian Radiopharmacy Servicing SubsidiaryEffective August 11, 2016, the Company entered into a share purchase agreement (“Australian Share Purchase Agreement”) with one of its existingradiopharmacy customers under which it sold all of the stock of its Australian radiopharmacy servicing subsidiary.The aggregate share sale price was AUD $2.0 million (approximately $1.5 million) in cash and also included a working capital adjustment ofapproximately AUD $2.0 million (approximately $1.5 million) for total expected proceeds of AUD $4.0 million (approximately $3.0 million) from the sale.As a result of this sale, the Company disposed of net assets of $2.2 million, primarily comprised of working capital accounts of $2.0 million.This share sale resulted in an adjusted pre-tax book gain of $0.5 million, which is recorded within gain on sales of assets in the accompanyingconsolidated statements of operations for the year ended December 31, 2016. As a result of the sale of the Australian subsidiary, the Company reclassified$0.4 million from other comprehensive income to gain on sale of assets in the accompanying consolidated statements of operations for the year endedDecember 31, 2016.The Australian Share Purchase Agreement contains customary representations, warranties and covenants by each of the parties. Subject to certainlimitations, the buyer will be indemnified for damages resulting from breaches or inaccuracies of the Company’s representations, warranties and covenants inthe Australian Share Purchase Agreement.As part of the transaction, the Company and the buyer also entered into a long-term supply and distribution contract under which the Company willsupply the buyer and its subsidiaries with the Company’s products on commercial terms and under which the buyer has agreed to certain product minimumpurchase commitments.The Company does not believe this sale of certain net assets in the international segment constituted a strategic shift that would have a major effect onits operations or financial results.

These plans are administered by the Board of Directors and permit thegranting of stock options, stock appreciation rights, 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 is treated asa separate award.The Company has certain stock option and restricted stock awards outstanding under each of its equity incentive plans but, upon adoption of the 2015Plan, no longer grants new equity awards under its 2008 and 2013 Plans. The Company adopted its 2015 Plan in June 2015 and subsequently amended theplan in April 2016 to increase the common stock reserved under the plan by 2,140,000 shares to 4,555,277 shares. 114Table of ContentsStock-based compensation expense for both time based and performance based awards was recognized in the consolidated statements of operations asfollows: Year EndedDecember 31, (in thousands) 2016 2015 2014 Cost of goods sold $359 $192 $135 Sales and marketing 339 254 154 General and administrative 1,438 1,330 621 Research and development 388 226 121 Total stock-based compensation expense $ 2,524 $ 2,002 $ 1,031 Stock OptionsStock option awards under the 2015 Plan are granted with 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, typically four years, and performance based option awards vest based on the performance criteria specified inthe grant. All option awards have a ten-year contractual term. The Company recognizes compensation costs for its time based awards on a straight-line basisequal to the vesting period. The compensation cost for performance based awards is recognized on a graded vesting basis, based on the probability ofachieving the performance targets over the requisite service period for the entire award. The fair value of each option award is estimated on the date of grantusing a Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatilities are based on the historic volatility of aselected peer group. Expected dividends represent the dividends expected to be issued at the date of grant. The expected term of options represents the periodof time that options granted are expected to be outstanding. The risk-free interest rate assumption is the U.S. Treasury rate at the date of the grant which mostclosely resembles the expected life of the options.There were no stock options granted during the year ended December 31, 2016. The table below summarizes the key assumptions used in valuing stockoptions granted during the years ended December 31, 2015 and 2014: Year EndedDecember 31, 2015 2014Expected volatility 26.0 – 30.0% 27.0 – 35.0%Expected dividends — — Expected life (in years) 4.1 – 6.3 3.1 – 7.0Risk-free interest rate 1.3 – 1.9% 1.1 – 2.0% 115Table of ContentsA summary of option activity for 2016 is presented below: TimeBased PerformanceBased StockOptions Weighted-AverageExercisePrice Weighted-AverageRemainingContractualTerm(Years) AggregateIntrinsicValue Outstanding at January 1, 2016 945,043 235,930 1,180,973 $10.95 4.5 $— Options granted — — — — Options cancelled (63,387) (12,268) (75,655) 16.26 Options exercised (37,920) (3,056) (40,976) 5.62 Options forfeited and expired (25,405) (1,600) (27,005) 15.66 Outstanding at December 31, 2016 818,331 219,006 1,037,337 10.63 3.3 $1,915,000 Vested and expected to vest at December 31, 2016 801,677 210,929 1,012,606 10.58 3.3 $1,880,000 Exercisable at December 31, 2016 648,149 203,302 851,451 10.39 3.2 $1,625,000 The weighted-average grant-date fair values of options granted during the years ended December 31, 2015 and 2014 were $1.44 and $1.70,respectively.

Changes in and Disagreements with Accountants on Accounting and Financial DisclosureNot applicable.Item 9A. Controls and ProceduresDisclosure Controls and ProceduresThe Company’s management, with the participation of the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), has evaluated theeffectiveness of the Company’s disclosure controls and procedures, as such term is defined under Rule 13a-15(e) or 15d-15(e) promulgated under theSecurities Exchange Act of 1934, as amended (the “Exchange Act”). Based on this evaluation, our CEO and CFO concluded that our disclosure controls andprocedures were effective as of the end of the period covered by this report.Management’s Annual Report on Internal Control Over Financial ReportingOur management, with the participation of our CEO and CFO, is responsible for establishing and maintaining adequate internal control over financialreporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control system is designed to provide reasonable assurance to ourmanagement and Board of Directors regarding the preparation and fair presentation of published financial statements.Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. In making its assessment ofinternal control over financial reporting, our management used the criteria set forth by the Committee of Sponsoring Organizations of the TreadwayCommission in Internal Control—Integrated Framework (2013). Based on this assessment, management concluded that, as of December 31, 2016, ourinternal control over financial reporting was effective.We do not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting in thisAnnual Report on Form 10-K pursuant to the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”). As a company with less than$1 billion in revenue during our last fiscal year, we qualify as an “emerging growth company,” as defined in the JOBS Act. An emerging growth companymay take advantage of specified reduced reporting and other regulatory requirements or up to five years that are otherwise applicable generally to publiccompanies. These provisions include, among other matters: • Exemption from the auditor attestation requirement on the effectiveness of our system of internal control over financial reporting; • Exemption from compliance with any new requirements adopted by the Public Company Accounting Oversight Board requiring mandatoryaudit firm rotation or a supplement to the auditor’s report in which the auditor would be required to provide additional information about theaudit and the financial statements of the issuer; • Exemption from the requirement to seek non-binding advisory votes on executive compensation and golden parachute arrangements; and • Reduced disclosure about executive compensation arrangements.We will remain an emerging growth company until December 31, 2020 unless, prior to that time, we have (i) more than $1 billion in annual revenue,(ii) have a market value for our common stock held by non-affiliates of more than $700 million as of the last day of our second fiscal quarter of the fiscal yearwhen a determination is made that we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 promulgated under the Securities Exchange Actof 1934, as amended, or the Exchange Act, or (iii) issue more than $1 billion of non-convertible debt over a three-year period. As a result, we were notrequired to have our independent registered public accounting firm attest to, and report on, internal controls over financial reporting. 121Table of ContentsChanges in Internal Control Over Financial ReportingThere have been no changes during the quarter ended December 31, 2016 in our internal control over financial reporting (as defined in Rule 13a-15(f)promulgated under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.Item 9B.
