We look forward to the results of an ongoing Phase 2 trial of anti-LINGO-1 in MS, which we expect to see in 2016. Beyond these accomplishments, we made additional progress in our clinical pipeline: Along with these milestones, we also have early- and mid-stage studies underway for lupus nephritis, idiopathic pulmonary fibrosis and stroke. As we look further into the future, our investments in novel science have helped accelerate the discovery of new targets and the development of therapies that we believe will enable us to make a genuine impact for patients. 4 | B I O G E N 2 0 1 4 A N N U A L R E P O R T 46861_Text.indd 4 46861_Text.indd 4 4/16/15 1:09 PM 4/16/15 1:09 PM 46861_Text.indd 5 46861_Text.indd 5 4/16/15 1:09 PM 4/16/15 1:09 PM S C I E N C E T H A T T R U L Y M A T T E R S | 5 We are integrating genomics into our of the medicines we are developing — discovery and development efforts, with and whether experimental and existing great promise for how we target diseases therapies are effectively hitting their in the future: targets. • Our two amyotrophic lateral sclerosis • Through an innovative collaboration (ALS) consortia, made up of leading with Google [X] Life Sciences, academic partners from across the we are pioneering the use of U.S., are yielding important insights emerging technologies to improve into the potential treatments for this our understanding of treatment effects devastating disease.

We believe our efforts in biosimilars enable us to participate in a valuable and growing business while offering an alternative for payers and health systems to reduce the burden of treatment costs. We have made a significant commitment to this space and believe our expertise in protein engineering and biologics manufacturing will continue to advance high-quality treatments. We support patients and their caregivers with a range of best-in-class services and programs under the MS ActiveSource® umbrella to help with the informational, emotional and logistical considerations that are part of living with MS. We also help patients and their families address the financial impact of treatment through our ActiveAccess™ program. In 2014, we provided financial assistance valued at more than $1 billion in the form of free drug and insurance copayment support, infusion assistance and charitable contributions.

Selected Financial Data and Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations included in this report. A discussion of the risks attendant to our operations is set forth in the “Risk Factors” section of this report. Multiple Sclerosis (MS) Products We develop, manufacture and market a number of products designed to treat patients with MS. MS is a progressive neurological disease in which the body loses the ability to transmit messages along nerve cells, leading to a loss of muscle control, paralysis and, in some cases, death. Patients with active relapsing MS experience an uneven pattern of disease progression characterized by periods of stability that are interrupted by flare-ups of the disease after which the patient returns to a new baseline of functioning. Our MS products include: • AVONEX (interferon beta-1a), an intramuscular injectable therapy, indicated for the treatment of patients with relapsing forms of MS. AVONEX is a recombinant form of the interferon beta protein produced in the body in response to viral infection. The principal markets for AVONEX are the U.S., United Kingdom, France, Germany, Italy and Spain. • PLEGRIDY (peginterferon beta-1a), a subcutaneous injectable therapy, indicated in the U.S. for the treatment of patients with relapsing forms of MS and in the European Union (E.U.) for relapsing-remitting MS (RRMS). PLEGRIDY received approval from the European Commission (EC) in July 2014 and the U.S. Food and Drug Administration (FDA) in August 2014. • • TECFIDERA (dimethyl fumarate), an oral therapy indicated in the U.S. for the treatment of patients with relapsing forms of MS and in the EU for people with RRMS. TECFIDERA was approved by the FDA in March 2013 and the EC in February 2014. TYSABRI (natalizumab), a monoclonal antibody approved in numerous countries as a monotherapy for the treatment of patients with relapsing forms of MS. TYSABRI is also approved in the U.S. to treat Crohn's disease, an inflammatory disease of the intestines. The principal markets for TYSABRI in MS are the U.S., the United Kingdom, France, Germany, Italy and Spain. TYSABRI was approved in Japan in March 2014. 2 • FAMPYRA (prolonged-release fampridine tablets), is indicated for the improvement of walking ability in adult patients with MS. FAMPYRA is a prolonged-release tablet formulation of the drug fampridine. We have a license from Acorda Therapeutics, Inc. (Acorda) to develop and commercialize FAMPYRA in all markets outside the U.S. Our principal markets for FAMPRYA are France, Germany, Spain and Canada. For information about our agreement with Acorda, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included in this report. Hemophilia Products We develop, manufacture and market products designed to treat patients with hemophilia A and B. Hemophilia A is caused by having substantially reduced or no Factor VIII activity and hemophilia B is caused by having substantially reduced or no Factor IX activity, each of which is needed for normal blood clotting. People with hemophilia A and B experience bleeding episodes that may cause pain, irreversible joint damage and life-threatening hemorrhages. Prophylactic infusions of Factor VIII or Factor IX, as applicable, temporarily replace clotting factor necessary to control bleeding and prevent new bleeding episodes. Our products for hemophilia A and B include: • ALPROLIX [Coagulation Factor IX (Recombinant), Fc Fusion Protein], a recombinant DNA-derived, coagulation Factor IX concentrate indicated in the U.S. for treatment in adults and children with hemophilia B for control and prevention of bleeding episodes, perioperative management and routine prophylaxis to prevent or reduce the frequency of bleeding episodes. ALPROLIX was approved by the FDA in March 2014 and in Japan in June 2014. • ELOCTATE [Antihemophilic Factor (Recombinant), Fc Fusion Protein], a recombinant DNA-derived, antihemophilic factor indicated in the U.S. for treatment in adults and children with hemophilia A for control and prevention of bleeding episodes, perioperative management and routine prophylaxis to prevent or reduce the frequency of bleeding episodes. ELOCTATE was approved by the FDA in June 2014 and in Japan in December 2014. We collaborate with Swedish Orphan Biovitrum AB (Sobi) to jointly develop and commercialize Factor VIII and Factor IX hemophilia products, including ELOCTATE and ALPROLIX. For information about our agreement with Sobi, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included in this report. Genentech Collaboration We collaborate with Genentech, Inc. (Genentech), a wholly-owned member of the Roche Group, on the development and commercialization of RITUXAN. We also share operating profits and losses relating to GAZYVA with Genentech in the U.S. The Roche Group and its sub-licensees maintain sole responsibility for the development, manufacturing and commercialization of GAZYVA in the U.S. For information about our unconsolidated joint business and agreement with Genentech, please read Note 1, Summary of Significant Accounting Policies and Note 20, Collaborative and Other Relationships to our consolidated financial statements included in this report. • RITUXAN (rituximab), a widely prescribed monoclonal antibody used to treat non-Hodgkin's lymphoma, rheumatoid arthritis, chronic lymphocytic leukemia (CLL) and two forms of ANCA-associated vasculitis. Non-Hodgkin's lymphoma and CLL are cancers that affect lymphocytes, which are a type of white blood cell that help to fight infection. Rheumatoid arthritis is a chronic disease that occurs when the immune system mistakenly attacks the body's joints, resulting in inflammation, pain and joint damage. ANCA-associated vasculitis is a rare autoimmune disease that largely affects the small blood vessels of the kidneys, lungs, sinuses, and a variety of other organs. • GAZYVA (obinutuzumab), in combination with chlorambucil, is indicated for the treatment of patients with previously untreated CLL. The FDA granted GAZYVA breakthrough therapy designation due to the significance of the positive progression-free survival results from the Phase 3 CLL11 clinical trial and the serious and life threatening nature of CLL. GAZYVA was approved by the FDA in November 2013. Other • FUMADERM (fumaric acid esters), a prolonged-release tablet formulation approved in Germany only for the treatment of adult patients with moderate to severe plaque psoriasis. Psoriasis is a skin disease in which cells build up on the skin surface and form scales and red patches. 3 Marketing and Distribution We promote our products in the U.S., most of the major countries of the E.U. and Japan primarily through our own sales forces and marketing groups. In some countries, particularly in areas where we continue to expand into new geographic areas, we partner with third parties. We focus our sales and marketing efforts on specialist physicians in private practice or at major medical centers. We use customary pharmaceutical company practices to market our products and to educate physicians, such as sales representatives calling on individual physicians, advertisements, professional symposia, direct mail, public relations and other methods. We provide customer service and other related programs for our products, such as disease and product specific websites, insurance research services and order, delivery and fulfillment services. We have also established programs in the U.S. which provide qualified uninsured or underinsured patients with marketed products at no or reduced charge, based on specific eligibility criteria. We distribute our products in the U.S. principally through wholesale distributors of pharmaceutical products, mail order specialty distributors or shipping service providers. In other countries, the distribution of our products varies from country to country, including through wholesale distributors of pharmaceutical products and third party distribution partners who are responsible for most marketing and distribution activities. RITUXAN and GAZYVA are marketed and distributed by the Roche Group and its sublicensees. Our product sales to two wholesale distributors, AmerisourceBergen and McKesson, each accounted for more than 10% of our total revenues for the years ended December 31, 2014, 2013 and 2012, and on a combined basis, these wholesale distributors accounted for approximately 60%, 56% and 30% of our gross product revenues for such years, respectively. Research and Development Programs A commitment to research is fundamental to our company’s mission. Our research and development strategy is to discover and develop differentiated molecules that improve safety or efficacy for unmet medical needs. By applying our expertise in biologics and our growing capabilities in small molecule, antisense, gene therapy, gene editing and other technologies, we target specific medical needs where new or better treatments are needed. We intend to continue committing significant resources to research and development opportunities. As part of our ongoing research and development efforts, we have devoted significant resources to conducting clinical studies to advance the development of new pharmaceutical products and technologies and to explore the utility of our existing products in treating disorders beyond those currently approved in their labels. For the years ended December 31, 2014, 2013 and 2012, research and development expenses were $1,893.4 million, $1,444.1 million and $1,334.9 million, respectively. The table below highlights our current research and development programs that are in clinical trials. Drug development involves a high degree of risk and investment, and the status, timing and scope of our development programs are subject to change. Important factors that could adversely affect our drug development efforts are discussed in the “Risk Factors” section of this report. 4 Therapeutic Area Neurology Product Candidate Targeted Indications Collaborator (1) Status ZINBRYTA (daclizumab high yield process) MS AbbVie Biotherapeutics Phase 3 completed; Expect to submit MAA to FDA and EMA in 2015 TYSABRI (natalizumab) Secondary progressive MS ISIS - SMNRx Anti-LINGO Neublastin BIIB037 BAN2401 E2609 ISIS - DMPKRx BIIB061 Hematology ALPROLIX [Coagulation Factor IX (Recombinant), Fc Fusion Protein] ELOCTATE [Antihemophilic Factor (Recombinant), Fc Fusion Protein] Acute Ischemic Stroke Spinal muscular atrophy Acute Optic Neuritis MS Neuropathic pain Alzheimer’s disease Alzheimer’s disease Alzheimer’s disease Myotonic Dystrophy MS Hemophilia B Hemophilia A Immunology STX-100 Idiopathic pulmonary fibrosis Anti-TWEAK Anti-CD40 Ligand Anti-BDCA2 Lupus nephritis Systemic lupus erythematosus Systemic lupus erythematosus None None Isis Pharmaceuticals None None None Neurimmune SubOne AG Eisai Eisai Isis Pharmaceuticals None Phase 3 Phase 2 Phase 3 Phase 2 Phase 2 Phase 2 Phase 1b; Preparing for Phase 3 Phase 2 Phase 2 Phase 1 Phase 1 Swedish Orphan Biovitrum Expect to submit MAA to EMA in 2015 Swedish Orphan Biovitrum MAA submitted and under regulatory review by EMA None None UCB Pharma None Phase 2a Phase 2 Phase 1b Phase 1 ........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Late Stage Product Candidates Additional information about our late stage product candidates, which includes programs in Phase 3 development or in registration stage, is set forth below. ZINBRYTA (daclizumab high yield process) ZINBRYTA is a monoclonal antibody that is being tested in RRMS. In June 2014, we announced positive top-line results from the Phase 3 DECIDE clinical trial, which investigated ZINBRYTA as a potential once-monthly, subcutaneous treatment for RRMS. Results showed that ZINBRYTA was superior on the study's primary endpoint, demonstrating a statistically significant reduction in annualized relapse rates when compared to interferon beta-1a (AVONEX). TYSABRI (natalizumab) In May 2013, we completed patient enrollment in a Phase 3 study of TYSABRI in secondary progressive MS, known as ASCEND. The study has a duration of approximately two years and involves approximately 875 patients. Secondary progressive MS is characterized by a steady progression of nerve damage, symptoms and disability. ELOCTATE [Antihemophilic Factor (Recombinant), Fc Fusion Protein] In June 2014, ELOCTATE, a recombinant factor VIII Fc fusion protein (rFVIIIFc), was approved by the FDA for the treatment of hemophilia A. In October 2014, we submitted a marketing authorization application (MAA) to the European Medicines Agency (EMA) for ELOCTA, the trade name for ELOCTATE in the E.U. The regulatory application included results from A-LONG, the pivotal Phase 3 clinical study that examined the efficacy, safety and pharmacokinetics of rFVIIIFc in males 12 years of age and older with severe hemophilia A and from Kids A-LONG, the Phase 3 clinical study that evaluated the efficacy and safety of rFVIIIFc in children with hemophilia A under the age of 12. 5 ALPROLIX [Coagulation Factor IX (Recombinant), Fc Fusion Protein] In March 2014, ALPROLIX was approved by the FDA for the treatment of hemophilia B. Pediatric data will be required as part of the MAA for ALPROLIX that we plan to submit to the EMA. We have initiated Kids B-LONG, a global pediatric study evaluating the efficacy and safety of recombinant factor IX Fc fusion protein (rFIXFc) in children with hemophilia B under the age of 12. GAZYVA The Roche Group is managing the following Phase 3 studies of GAZYVA: • GOYA: investigating the efficacy and safety of GAZYVA in combination with CHOP chemotherapy compared to RITUXAN with CHOP chemotherapy in previously untreated patients with CD20-positive diffuse large B-cell lymphoma. • GALLIUM: investigating the efficacy and safety of GAZYVA in combination with chemotherapy followed by maintenance with GAZYVA compared to RITUXAN in combination with chemotherapy followed by maintenance with RITUXAN in previously untreated patients with indolent non-Hodgkin's lymphoma. • GADOLIN: investigating the efficacy and safety of GAZYVA plus bendamustine compared with bendamustine alone in patients with RITUXAN-refractory, indolent non-Hodgkin's lymphoma. In February 2015, the Roche Group announced positive results from the Phase 3 GADOLIN study. At a pre-planned interim analysis, an independent data monitoring committee determined that the study met its primary endpoint early, showing that people lived significantly longer without disease worsening or death (progression-free survival) when treated with GAZYVA plus bendamustine followed by GAZYVA alone, compared to bendamustine alone. ISIS-SMNRx In August 2014, Isis Pharmaceuticals, Inc. (Isis) announced the initiation of a pivotal Phase 3 study evaluating ISIS- SMNRx in infants with spinal muscular atrophy (SMA), the most common genetic cause of infant mortality. This Phase 3 study, known as ENDEAR, is a randomized, double-blind, sham-procedure controlled thirteen month study in approximately 110 infants diagnosed with SMA. The study will evaluate the efficacy and safety of a 12mg dose of ISIS-SMNRx with a primary endpoint of survival or permanent ventilation. In November 2014, Isis announced the initiation of a pivotal Phase 3 study evaluating the efficacy and safety of ISIS- SMNRx in non-ambulatory children with SMA. This Phase 3 study, known as CHERISH, is a randomized, double-blind, sham- procedure controlled fifteen month study in approximately 120 children with SMA. The study will evaluate the efficacy and safety of a 12mg dose of ISIS-SMNRx with a primary endpoint of a change in the Hammersmith Functional Motor Scale- Expanded, a validated method to measure changes in muscle function in patients with SMA.

In November 2014, Sobi exercised its opt-in right to assume final development and commercialization of ELOCTA in those territories. Patents and Other Proprietary Rights Patents are important to obtaining and protecting exclusive rights in our drugs and drug candidates. We regularly seek patent protection in the U.S. and in selected countries outside the U.S. for inventions originating from our research and development efforts. In addition, we license rights to various patents and patent applications. U.S. patents, as well as most foreign patents, are generally effective for 20 years from the date the earliest application was filed; however, U.S. patents that issue on applications filed before June 8, 1995 may be effective until 17 years from the issue date, if that is later than the 20 year date. In some cases, the patent term may be extended to recapture a portion of the term lost during FDA regulatory review or, in the case of the U.S., because of U.S. Patent and Trademark Office (USPTO) delays in prosecuting the application. Specifically, in the U.S., under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly known as the Hatch-Waxman Act, the term of a patent that covers an FDA-approved drug may also be eligible for patent term extension (for up to five years, but not beyond a total of 14 years from the date of product approval) as compensation for patent term lost during the FDA regulatory review process. The duration and extension of the term of foreign patents varies similarly, in accordance with local law. For example, supplementary protection certificates (SPCs) on some of our products have been granted in a number of European countries, compensating in part for delays in obtaining marketing approval. 7 Regulatory exclusivity, which may consist of regulatory data protection and market protection, also can provide meaningful protection for our products. Regulatory data protection provides to the holder of a drug or biologic marketing authorization, for a set period of time, the exclusive use of the proprietary pre-clinical and clinical data that it created at significant cost and submitted to the applicable regulatory authority to obtain approval of its product. Our products also may qualify for market protection from regulatory authorities, pursuant to which a regulatory authority may not permit for a set period of time, the approval or commercialization of another product containing the same active ingredient(s) as our product. After that set period of time, third parties are then permitted to rely upon our data to obtain approval of their abbreviated applications to market (e.g., generic drugs and biosimilars). Although the World Trade Organization's agreement on trade- related aspects of intellectual property rights (TRIPS) requires signatory countries to provide regulatory exclusivity to innovative pharmaceutical products, implementation and enforcement varies widely from country to country. We also rely upon other forms of unpatented confidential information to remain competitive. We protect such information principally through confidentiality agreements with our employees, consultants, outside scientific collaborators, scientists whose research we sponsor and other advisers. In the case of our employees, these agreements also provide, in compliance with relevant law, that inventions and other intellectual property conceived by such employees during their employment shall be our exclusive property. Our trademarks are important to us and are generally covered by trademark applications or registrations in the USPTO and the patent or trademark offices of other countries. We also use trademarks licensed from third parties, such as the trademark FAMPYRA which we license from Acorda Therapeutics. Trademark protection varies in accordance with local law, and continues in some countries as long as the trademark is used and in other countries as long as the trademark is registered. Trademark registrations generally are for fixed but renewable terms. A discussion of certain risks and uncertainties that may affect our patent position and proprietary rights is set forth in the “Risk Factors” section of this report. Additional information about the patents, expected regulatory exclusivities and other proprietary rights covering our marketed products is set forth below. AVONEX and PLEGRIDY We have several U.S. patents and patent applications, and a number of corresponding foreign counterparts, related to AVONEX and/or PLEGRIDY. Our U.S. patent no. 7,588,755 claims the use of recombinant beta interferon for immunomodulation or treating a viral condition, viral disease, cancers or tumors. This patent, which expires in September 2026, covers the treatment of MS with AVONEX and PLEGRIDY. A discussion of legal proceedings related to this patent is set forth in Note 21, Litigation to our consolidated financial statements included in this report. Additionally, we and another party each own a pending U.S. patent application related to recombinant interferon-beta protein. These applications, which fall outside of the General Agreement on Tariffs and Trade (GATT) amendments to the U.S. patent statute, are not published by the USPTO and, if they mature into granted patents, may be entitled to a term of seventeen years from the grant date. There is a pending interference proceeding in the USPTO involving these applications. We do not know whether either of these applications will mature into patents with claims relevant to AVONEX or to PLEGRIDY. Additional protection for PLEGRIDY is provided by patents and patent applications with expiration dates out to 2025 in the U.S. and 2019 in the E.U., with the potential for patent term extension. PLEGRIDY is also entitled to regulatory exclusivity until 2026 in the U.S. and 2024 in the E.U. TECFIDERA We have several U.S. patents and patent applications, and a number of corresponding foreign counterparts, related to TECFIDERA. Our principal U.S. patents and expiration dates, subject to pending applications for patent term extension, are: • U.S. patent no. 6,509,376, having claims to formulations of dimethyl fumarate for use in the treatment of autoimmune diseases including MS, expiring in 2019; • U.S. patent no. 7,320,999, having claims to a method of treating MS using dimethyl fumarate, expiring in 2020; • U.S. patent no. 7,619,001, having claims to a method of treating MS using dimethyl fumarate, monomethyl fumarate, or a combination thereof, expiring in 2018; 8 • U.S. patent no. 7,803,840, having claims to a method of treating an autoimmune disease selected from autoimmune polyarthritis and MS using dimethyl fumarate, expiring in 2018; • U.S. patent no. 8,399,514, covering the dosing regimen of 480 mg per day of dimethyl fumarate, monomethyl fumarate or combinations thereof for treating MS, expiring in 2028; • U.S. patent no. 8,524,773, having claims to a method of treating MS using dimethyl fumarate, expiring in 2018; and • U.S. patent no. 8,759,393, having claims to formulations of dimethyl fumarate, expiring in 2019. Our principal European patents and expiration dates, subject to pending applications for supplemental patent certificates, are: • European patent no. (EP) 1131065, directed to formulations of dimethyl fumarate and to uses thereof for treating autoimmune diseases, including MS, expiring in 2019; and • EP 2137537, the counterpart patent to our U.S. patent covering the dosing regimen of 480 mg per day of dimethyl fumarate or monomethyl fumarate for treating MS, expiring in 2028. In addition to patent protection, in the U.S. TECFIDERA is entitled to regulatory exclusivity until 2018. In the E.U., TECFIDERA is entitled to regulatory exclusivity until 2024. TYSABRI We have patents and patent applications covering TYSABRI in the U.S. and other countries. These patents and patent applications cover TYSABRI and related manufacturing methods, as well as various methods of treatment using the product. The principal patents covering the product and use of the product to treat MS are U.S. patent nos. 5,840,299 and 6,602,503 and EP 0804237, which expire between 2017 and 2020 (including supplementary protection certificates in many European countries). Additional U.S. and E.U. patents and applications covering methods of treatment using the product expire in 2023. In addition to patent protection, TYSABRI is entitled to regulatory exclusivity until 2016 in both the U.S. and the E.U. FAMPYRA We have an exclusive license under two European granted patents, several pending European patent applications and numerous corresponding non-U.S. counterpart applications related to FAMPYRA. EP 0484186B1 claims pharmaceutical formulations containing aminopyridines including fampridine. This patent expired in November 2011 but is subject to pending and granted supplemental protection certificates which, where granted, will extend the patent term to 2016 on a country-by- country basis. EP 1732548B1, which claims sustained-release aminopyridine compositions for increasing walking speed in patients with MS, and EP 2377536B1, which claims sustained-release aminopyridine compositions for treating multiple sclerosis, expire in 2025 but are subject to pending and granted supplemental protection certificates which, where granted, will extend one of the patents’ term to 2026 on a country-by-country basis. In addition to these patent rights, FAMPYRA is covered by regulatory exclusivity in Europe until 2021. ELOCTATE and ALPROLIX We have several U.S. patents and patent applications, and a number of corresponding foreign counterparts, related to ELOCTATE and ALPROLIX and their use. The principal patents include U.S. patents nos. 7,404,956, 8,329,182, 7,348,004 and 7,862,820. These patents will expire between 2024 and 2025, and some may be entitled to additional patent term pursuant to the patent term extension provisions of the U.S. patent laws. Related European patents EP 1624891 and EP 1625209 expire in 2024 and may be entitled to additional patent term in at least some countries upon approval. Additionally, pending patent applications, if granted, would provide additional patent protection through 2034. ELOCTATE and ALPROLIX are both entitled to regulatory exclusivity in the U.S. until 2026. RITUXAN and Anti-CD20 Antibodies We have several U.S. patents and patent applications, and numerous corresponding foreign counterparts, directed to anti- CD20 antibody technology, including RITUXAN. The principal patents with claims to RITUXAN or its uses expire in the U.S. between 2015 and 2018 and expired in the rest of the world in 2013, subject to any available patent term extensions. In addition, we and our collaborator Genentech, have additional patents and patent applications directed to anti-CD20 antibodies and their uses to treat various diseases. Genentech has principal responsibility for managing the intellectual property portfolio for RITUXAN and the other anti-CD20 antibodies under our agreements with Genentech. 9 Competition Competition in the biopharmaceutical industries is intense and comes from many sources, including specialized biotechnology firms and large pharmaceutical companies. Many of our competitors are working to develop products similar to those we are developing or already market and have considerable experience in undertaking clinical trials and in obtaining regulatory approval to market pharmaceutical products. Certain of these companies have substantially greater financial, marketing and research and development resources than we do. We believe that competition and leadership in the industry is based on managerial and technological excellence and innovation as well as establishing patent and other proprietary positions through research and development. The achievement of a leadership position also depends largely upon our ability to identify and exploit commercially the products resulting from research and the availability of adequate financial resources to fund facilities, equipment, personnel, clinical testing, manufacturing and marketing. Another key aspect of remaining competitive within the industry is recruiting and retaining leading scientists and technicians. We believe that we have been successful in attracting skilled and experienced scientific personnel. Competition among products approved for sale may be based, among other things, on patent position, product efficacy, safety, convenience/delivery devices, reliability, availability and price. In addition, early entry of a new pharmaceutical product into the market may have important advantages in gaining product acceptance and market share. Accordingly, the relative speed with which we can develop products, complete the testing and approval process and supply commercial quantities of products will have an important impact on our competitive position. The introduction of new products or technologies, including the development of new processes or technologies by competitors or new information about existing products may result in increased competition for our marketed products or could result in pricing pressure on our products. It is also possible that the development of new treatment options or standards of care could reduce the use of our products or may limit the utility and application of ongoing clinical trials for our product candidates. We may also face increased competitive pressures as a result of generics and the emergence of biosimilars in the U.S. and E.U. If a generic or biosimilar version of one of our products were approved, it could reduce our sales of that product. Additional information about the competition that our marketed products face is set forth below. AVONEX, PLEGRIDY, TYSABRI and TECFIDERA AVONEX, PLEGRIDY, TYSABRI and TECFIDERA each compete with one or more of the following products: Competing Product COPAXONE (glatiramer acetate) REBIF (interferon-beta-1) BETASERON/BETAFERON (interferon-beta-1b) EXTAVIA (interferon-beta-1b) GILENYA (fingolimod) AUBAGIO (teriflunomide) LEMTRADA (alemtuzumab) Competitor Teva Pharmaceuticals Industries Ltd. Merck KGaA (and co-promoted with Pfizer Inc. in the U.S.) Bayer Group Novartis AG Novartis AG Sanofi Sanofi Competition in the MS market is intense. Along with us, a number of companies are working to develop additional treatments for MS that may in the future compete with AVONEX, PLEGRIDY, TYSABRI, TECFIDERA or all of them. In addition, the commercialization of our own products, including new products such as TECFIDERA and PLEGRIDY, and the possible future introduction of generics, related prodrug derivatives or biosimilars of existing products may negatively impact future sales of our MS products. FAMPYRA FAMPYRA is indicated as a treatment to improve walking in adult patients with MS who have walking disability and is the first treatment that addresses this unmet medical need with demonstrated efficacy in people with all types of MS. FAMPYRA is currently the only therapy approved to improve walking in patients with MS. FUMADERM FUMADERM competes with several different types of therapies in the psoriasis market within Germany, including oral systemics such as methotrexate and cyclosporine. 10 RITUXAN and GAZYVA in Oncology RITUXAN and GAZYVA compete with several different types of therapies in the oncology market, including: Competing Product TREANDA (bendamustine HCL) ARZERRA (ofatumumab) IMBRUVICA (ibrutinib) ZYDELIG (idelalisib) Competitor Cephalon (Teva Pharmaceuticals) GenMab in collaboration with GlaxoSmithKline Pharmacyclics and Janssen Gilead We also expect that over time GAZYVA will compete with RITUXAN in the oncology market. In addition, we are aware of other anti-CD20 molecules, including biosimilars, in development that, if successfully developed and approved, may compete with RITUXAN and GAZYVA in the oncology market. RITUXAN in Rheumatoid Arthritis (RA) RITUXAN competes with several different types of therapies in the RA market, including: Competing Product/Type of Therapy Traditional Therapies: Competitor Disease-modifying anti-rheumatic drugs such as steroids, methotrexate and cyclosporine Numerous competitors TNF Inhibitors: REMICADE (infliximab) SIMPONI and SIMPONI ARIA (golimumab) HUMIRA (adalimumab) ENBREL (etanercept) CIMZIA (certolizumab pegol) ORENCIA (abatacept) ACTEMRA (tocilizumab) XELJANZ (tofacitinib) Johnson & Johnson Johnson & Johnson AbbVie Amgen and Pfizer UCB, S.A. Bristol-Myers Squibb Company Roche Group Pfizer We are also aware of other products, including biosimilars, in development that, if successfully developed and approved, may compete with RITUXAN in the RA market. ELOCTATE and ALPROLIX ELOCTATE and ALPROLIX compete with recombinant short-acting Factor VIII and IX products, respectively, including: Competing Product ELOCTATE: Competitor ADVATE [Antihemophilic Factor (Recombinant)] Baxter KOGENATE FS [Antihemophilic Factor (Recombinant)] Bayer HELIXATE FS [Antihemophilic Factor (Recombinant)] XYNTHA [Antihemophilic Factor (Recombinant)], Plasma/Albumin-Free CSL Behring Pfizer ALPROLIX: BENEFIX Coagulation Factor IX (Recombinant) RIXUBIS [Coagulation Factor IX (Recombinant)] Pfizer Baxter Our hemophilia products also compete with a number of plasma-derived short-acting Factor VIII and IX products. We are also aware of other longer-acting products as well as other technologies, such as gene therapies, that are in development, and if successfully developed and approved may compete with our hemophilia products. 11 Regulatory Our current and contemplated activities and the products and processes that will result from such activities are subject to substantial government regulation. Regulation of Pharmaceuticals Product Approval and Post-Approval Regulation in the United States Before new pharmaceutical products may be sold in the U.S., preclinical studies and clinical trials of the products must be conducted and the results submitted to the FDA for approval. With limited exceptions, the FDA requires companies to register both pre-approval and post-approval clinical trials and disclose clinical trial results in public databases. Failure to register a trial or disclose study results within the required time periods could result in penalties, including civil monetary penalties. Clinical trial programs must establish efficacy, determine an appropriate dose and dosing regimen, and define the conditions for safe use. This is a high-risk process that requires stepwise clinical studies in which the candidate product must successfully meet predetermined endpoints. The results of the preclinical and clinical testing of a product are then submitted to the FDA in the form of a Biologics License Application (BLA) or a New Drug Application (NDA). In response to a BLA or NDA, the FDA may grant marketing approval, request additional information or deny the application if it determines the application does not provide an adequate basis for approval. Product development and receipt of regulatory approval takes a number of years, involves the expenditure of substantial resources and depends on a number of factors, including the severity of the disease in question, the availability of alternative treatments, potential safety signals observed in preclinical or clinical tests, and the risks and benefits of the product as demonstrated in clinical trials. The FDA has substantial discretion in the product approval process, and it is impossible to predict with any certainty whether and when the FDA will grant marketing approval. The agency may on occasion require the sponsor of a BLA or NDA to conduct additional clinical studies or to provide other scientific or technical information about the product, and these additional requirements may lead to unanticipated delay or expense. Furthermore, even if a product is approved, the approval may be subject to limitations based on the FDA's interpretation of the existing pre-clinical or clinical data. The FDA has developed four distinct approaches intended to make therapeutically important drugs available as rapidly as possible, especially when the drugs are the first available treatment or have advantages over existing treatments: accelerated approval, fast track, breakthrough therapy, and priority review. The FDA may grant “accelerated approval” status to products that treat serious or life-threatening illnesses and that provide meaningful therapeutic benefits to patients over existing treatments. Under this pathway, the FDA may approve a product based on surrogate endpoints, or clinical endpoints other than survival or irreversible morbidity. When approval is based on surrogate endpoints or clinical endpoints other than survival or morbidity, the sponsor will be required to conduct additional post-approval clinical studies to verify and describe clinical benefit. Under the agency's accelerated approval regulations, if the FDA concludes that a drug that has been shown to be effective can be safely used only if distribution or use is restricted, it may require certain post-marketing restrictions as necessary to assure safe use. In addition, for products approved under accelerated approval, sponsors may be required to submit all copies of their promotional materials, including advertisements, to the FDA at least thirty days prior to initial dissemination. The FDA may withdraw approval under accelerated approval after a hearing if, for instance, post-marketing studies fail to verify any clinical benefit, it becomes clear that restrictions on the distribution of the product are inadequate to ensure its safe use, or if a sponsor fails to comply with the conditions of the accelerated approval. In addition, the FDA may grant “fast track” status to products that treat serious diseases or conditions and fill an unmet medical need. Fast track is a process designed to expedite the review of such products by providing, among other things, more frequent meetings with the FDA to discuss the product's development plan, more frequent written correspondence from the FDA about trial design, eligibility for accelerated approval, and rolling review, which allows submission of individually completed sections of a NDA or BLA for FDA review before the entire filing is completed. Fast track status does not ensure that a product will be developed more quickly or receive FDA approval. The FDA may also grant “breakthrough therapy” status to drugs designed to treat, alone or in combination with another drug or drugs, a serious or life-threatening disease or condition and for which preliminary evidence suggests a substantial improvement over existing therapies. Such drugs need not address an unmet need, but are nevertheless eligible for expedited review if they offer the potential for an improvement. Breakthrough therapy status entitles the sponsor to earlier and more frequent meetings with the FDA regarding the development of nonclinical and clinical data and permits the FDA to offer product development or regulatory advice for the purpose of shortening the time to product approval. Breakthrough therapy status does not guarantee that a product will be developed or reviewed more quickly and does not ensure FDA approval. 12 Finally, the FDA may grant “priority review” status to products that offer major advances in treatment or provide a treatment where no adequate therapy exists. Priority review is intended to reduce the time it takes for the FDA to review a NDA or BLA. Regardless of the approval pathway employed, the FDA may require a sponsor to conduct additional post-marketing studies as a condition of approval to provide data on safety and effectiveness. If a sponsor fails to conduct the required studies, the agency may withdraw its approval. In addition, if the FDA concludes that a drug that has been shown to be effective can be safely used only if distribution or use is restricted, it can mandate post-marketing restrictions as necessary to assure safe use. In such a case, the sponsor may be required to establish rigorous systems to assure use of the product under safe conditions. These systems are usually referred to as Risk Evaluation and Mitigation Strategies (REMS). The FDA can impose financial penalties for failing to comply with certain post-marketing commitments, including REMS. In addition, any changes to an approved REMS must be reviewed and approved by the FDA prior to implementation. We monitor information on side effects and adverse events reported during clinical studies and after marketing approval and report such information and events to regulatory agencies. Non-compliance with the FDA's safety reporting requirements may result in civil or criminal penalties. Side effects or adverse events that are reported during clinical trials can delay, impede, or prevent marketing approval. Based on new safety information that emerges after approval, the FDA can mandate product labeling changes, impose a new REMS or the addition of elements to an existing REMS, require new post-marketing studies (including additional clinical trials), or suspend or withdraw approval of the product. These requirements may affect our ability to maintain marketing approval of our products or require us to make significant expenditures to obtain or maintain such approvals. If we seek to make certain types of changes to an approved product, such as adding a new indication, making certain manufacturing changes, or changing manufacturers or suppliers of certain ingredients or components, the FDA will need to review and approve such changes in advance. In the case of a new indication, we are required to demonstrate with additional clinical data that the product is safe and effective for a use other than that initially approved. FDA regulatory review may result in denial or modification of the planned changes, or requirements to conduct additional tests or evaluations that can substantially delay or increase the cost of the planned changes. In addition, the FDA regulates all advertising and promotion activities and communications for products under its jurisdiction both before and after approval. A company can make only those claims relating to safety and efficacy that are approved by the FDA. However, physicians may prescribe legally available drugs for uses that are not described in the drug's labeling. Such off-label uses are common across medical specialties, and often reflect a physician's belief that the off-label use is the best treatment for patients. The FDA does not regulate the behavior of physicians in their choice of treatments, but the FDA regulations do impose stringent restrictions on manufacturers' communications regarding off-label uses. Failure to comply with applicable FDA requirements may subject a company to adverse publicity, enforcement action by the FDA, corrective advertising, and the full range of civil and criminal penalties available to the FDA. Regulation of Combination Products Combination products are defined by the FDA to include products comprised of two or more regulated components (e.g., a biologic and a device). Biologics and devices each have their own regulatory requirements, and combination products may have additional requirements. Some of our marketed products meet this definition and are regulated under this framework and similar regulations outside the U.S., and we expect that some of our pipeline product candidates may be evaluated for regulatory approval under this framework as well. Product Approval and Post-Approval Regulation Outside the United States We market our products in numerous jurisdictions outside the U.S. Most of these jurisdictions have product approval and post-approval regulatory processes that are similar in principle to those in the U.S. In Europe, where most of our ex-U.S. efforts are focused, there are several tracks for marketing approval, depending on the type of product for which approval is sought. Under the centralized procedure, a company submits a single application to the EMA. The marketing application is similar to the NDA or BLA in the U.S. and is evaluated by the Committee for Medicinal Products for Human Use (CHMP), the expert scientific committee of the EMA. If the CHMP determines that the marketing application fulfills the requirements for quality, safety, and efficacy, it will submit a favorable opinion to the EC. The CHMP opinion is not binding, but is typically adopted by the EC. A marketing application approved by the EC is valid in all member states. The centralized procedure is required for all biological products, orphan medicinal products, and new treatments for neurodegenerative disorders, and it is available for certain other products, including those which constitute a significant therapeutic, scientific or technical innovation. 13 In addition to the centralized procedure, Europe also has: (1) a nationalized procedure, which requires a separate application to and approval determination by each country; (2) a decentralized procedure, whereby applicants submit identical applications to several countries and receive simultaneous approval; and (3) a mutual recognition procedure, where applicants submit an application to one country for review and other countries may accept or reject the initial decision. Regardless of the approval process employed, various parties share responsibilities for the monitoring, detection, and evaluation of adverse events post-approval, including national authorities, the EMA, the EC, and the marketing authorization holder. In some regions, it is possible to receive an “accelerated” review whereby the national regulatory authority will commit to truncated review timelines for products that meet specific medical needs. Good Manufacturing Practices Regulatory agencies regulate and inspect equipment, facilities, and processes used in the manufacturing and testing of pharmaceutical and biologic products prior to approving a product. If, after receiving clearance from regulatory agencies, a company makes a material change in manufacturing equipment, location, or process, additional regulatory review and approval may be required. We also must adhere to current Good Manufacturing Practices (cGMP) and product-specific regulations enforced by regulatory agencies following product approval. The FDA, the EMA and other regulatory agencies also conduct periodic visits to re-inspect equipment, facilities, and processes following the initial approval of a product. If, as a result of these inspections, it is determined that our equipment, facilities, or processes do not comply with applicable regulations and conditions of product approval, regulatory agencies may seek civil, criminal, or administrative sanctions or remedies against us, including significant financial penalties and the suspension of our manufacturing operations. Good Clinical Practices The FDA, the EMA and other regulatory agencies promulgate regulations and standards for designing, conducting, monitoring, auditing and reporting the results of clinical trials to ensure that the data and results are accurate and that the rights and welfare of trial participants are adequately protected (commonly referred to as current Good Clinical Practices (cGCP)). Regulatory agencies enforce cGCP through periodic inspections of trial sponsors, principal investigators and trial sites, contract research organizations (CROs), and institutional review boards. If our studies fail to comply with applicable cGCP, the clinical data generated in our clinical trials may be deemed unreliable and relevant regulatory agencies may require us to perform additional clinical trials before approving our marketing applications. Noncompliance can also result in civil or criminal sanctions. We rely on third parties, including CROs, to carry out many of our clinical trial-related activities. Failure of such third parties to comply with cGCP can likewise result in rejection of our clinical trial data or other sanctions. Approval of Biosimilars In March 2010, U.S. healthcare reform legislation known as the Affordable Care Act, amended the Public Health Service Act (PHSA), to authorize the FDA to approve biological products, referred to as biosimilars or follow-on biologics, that are shown to be highly similar to previously approved biological products based upon potentially abbreviated data packages. The approval pathway for biosimilars does, however, grant a biologics manufacturer a 12 year period of exclusivity from the date of approval of its biological product before biosimilar competition can be introduced. The FDA has released draft guidance documents as part of the implementation of the abbreviated approval pathway for biosimilars and these have not yet been finalized. The FDA has indicated that it is still evaluating a number of relevant issues, and additional guidance documents are expected to be released, including guidance on the criteria for interchangeability (which the FDA has indicated would be a “higher standard” than biosimilarity), naming, labeling and clinical pharmacology. Biosimilars legislation has also been in place in the E.U. since 2003. In December 2012, guidelines issued by the EMA for approving biosimilars of marketed monoclonal antibody products became effective. In the E.U., biosimilars have been approved under a specialized pathway of centralized procedures. The pathway allows sponsors of a biosimilar to seek and obtain regulatory approval based in part on the clinical trial data of an innovator product to which the biosimilar has been demonstrated to be “similar”. In many cases, this allows biosimilars to be brought to market without conducting the full complement of clinical trials typically required for novel biologic drugs. 14 Orphan Drug Act Under the U.S. Orphan Drug Act, the FDA may grant orphan drug designation to drugs or biologics intended to treat a “rare disease or condition,” which generally is a disease or condition that affects fewer than 200,000 individuals in the U.S. If a product which has an orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, i.e., the FDA may not approve any other applications to market the same drug for the same indication for a period of seven years following marketing approval, except in certain very limited circumstances, such as if the later product is shown to be clinically superior to the orphan product. Legislation similar to the U.S. Orphan Drug Act has been enacted in other countries to encourage the research, development and marketing of medicines to treat, prevent or diagnose rare diseases. In the E.U., medicinal products intended for diagnosis, prevention or treatment of life-threatening or very serious diseases affecting less than five in 10,000 people receive 10-year market exclusivity, protocol assistance, and access to the centralized procedure for marketing authorization. Regulation Pertaining to Pricing and Reimbursement In both domestic and foreign markets, sales of our products depend, in part, on the availability and amount of reimbursement by third party payors, including governments and private health plans. Governments may regulate coverage, reimbursement and pricing of our products to control cost or affect utilization of our products. Private health plans may also seek to manage cost and utilization by implementing coverage and reimbursement limitations. Substantial uncertainty exists regarding the reimbursement by third party payors of newly approved health care products. The U.S. and foreign governments regularly consider reform measures that affect health care coverage and costs. For example, provisions of the Affordable Care Act have resulted in changes in the way health care is paid for by both governmental and private insurers, including increased rebates owed by manufacturers under the Medicaid Drug Rebate Program, annual fees and taxes on manufacturers of certain branded prescription drugs, the requirement that manufacturers participate in a discount program for certain outpatient drugs under Medicare Part D and the expansion of the number of hospitals eligible for discounts under Section 340B of the PHSA. Such reforms have had and are expected to continue to have a significant impact on our business. Within the U.S. Medicaid is a joint federal and state program that is administered by the states for low income and disabled beneficiaries. Under the Medicaid Drug Rebate Program, we are required to pay a rebate for each unit of product reimbursed by the state Medicaid programs. For most brand name drugs, the amount of the basic rebate for each product is set by law as the greater of 23.1% (17.1% for clotting factors and certain other products) of the average manufacturer price (AMP) or the difference between AMP and the best price available from us to any customer (with limited exceptions). The rebate amount must be adjusted upward if AMP increases more than inflation (measured by the Consumer Price Index - Urban). This adjustment can cause the total rebate amount to exceed the minimum 23.1% (or 17.1%) basic rebate amount. The rebate amount is calculated each quarter based on our report of current AMP and best price for each of our products to the Centers for Medicare & Medicaid Services (CMS). The requirements for calculating AMP and best price are complex. We are required to report any revisions to AMP or best price previously reported within a certain period, which revisions could affect our rebate liability for prior quarters. In addition, if we fail to provide information timely or we are found to have knowingly submitted false information to the government, the statute governing the Medicaid Drug Rebate Program provides for civil monetary penalties. Medicare is a federal program that is administered by the federal government that covers individuals age 65 and over as well as those with certain disabilities. Medicare Part B generally covers drugs that must be administered by physicians or other health care practitioners; are provided in connection with certain durable medical equipment; or are certain oral anti-cancer drugs and certain oral immunosuppressive drugs. Medicare Part B pays for such drugs under a payment methodology based on the average sales price (ASP) of the drugs. Manufacturers, including us, are required to provide ASP information to the CMS on a quarterly basis. The manufacturer-submitted information is used to calculate Medicare payment rates. The current payment rate for Medicare Part B drugs is ASP plus 6%. The payment rates for drugs in the hospital outpatient setting are subject to periodic adjustment. The CMS also has the statutory authority to adjust payment rates for specific drugs outside the hospital outpatient setting based on a comparison of ASP payment rates to widely available market prices or to AMP, which could decrease Medicare payment rates, but the authority has not yet been implemented. If a manufacturer is found to have made a misrepresentation in the reporting of ASP, the governing statute provides for civil monetary penalties. Medicare Part D provides coverage to enrolled Medicare patients for self-administered drugs (i.e., drugs that are not administered by a physician). Medicare Part D is administered by private prescription drug plans approved by the U.S. government and each drug plan establishes its own Medicare Part D formulary for prescription drug coverage and pricing, which the drug plan may modify from time-to-time. The prescription drug plans negotiate pricing with manufacturers and may condition formulary placement on the availability of manufacturer discounts. In addition, manufacturers, including us, are required to provide to CMS a 50% discount on brand name prescription drugs utilized by Medicare Part D beneficiaries when those beneficiaries reach the coverage gap in their drug benefits. 15 Our products are subject to discounted pricing when purchased by federal agencies via the Federal Supply Schedule (FSS). FSS participation is required for our products to be covered and reimbursed by the Veterans Administration, Department of Defense, Coast Guard, and Public Health Service (PHS). Coverage under Medicaid, Medicare and the PHS pharmaceutical pricing program is also conditioned upon FSS participation. FSS pricing is intended not to exceed the price that we charge our most-favored non-federal customer for a product. In addition, prices for drugs purchased by the Veterans Administration, Department of Defense (including drugs purchased by military personnel and dependents through the TriCare retail pharmacy program), Coast Guard, and PHS are subject to a cap on pricing equal to 76% of the non-federal average manufacturer price (non-FAMP). An additional discount applies if non-FAMP increases more than inflation (measured by the Consumer Price Index - Urban). In addition, if we fail to provide information timely or we are found to have knowingly submitted false information to the government, the governing statute provides for civil monetary penalties. To maintain coverage of our products under the Medicaid Drug Rebate Program and Medicare Part B, we are required to extend significant discounts to certain covered entities that purchase products under Section 340B of the PHS pharmaceutical pricing program. Purchasers eligible for discounts include hospitals that serve a disproportionate share of financially needy patients, community health clinics, hemophilia treatment centers and other entities that receive certain types of grants under the PHSA. For all of our products, we must agree to charge a price that will not exceed the amount determined under statute (the “ceiling price”) when we sell outpatient drugs to these covered entities. In addition, we may, but are not required to, offer these covered entities a price lower than the 340B ceiling price. The 340B discount formula is based on AMP and is generally similar to the level of rebates calculated under the Medicaid Drug Rebate Program. Outside the U.S. Outside the U.S., the E.U. represents our major market. Within the E.U., our products are paid for by a variety of payors, with governments being the primary source of payment. Governments may determine or influence reimbursement of products. Governments may also set prices or otherwise regulate pricing. Negotiating prices with governmental authorities can delay commercialization of our products. Governments may use a variety of cost-containment measures to control the cost of products, including price cuts, mandatory rebates, value-based pricing, and reference pricing (i.e., referencing prices in other countries and using those reference prices to set a price). Budgetary pressures in many E.U. countries are continuing to cause governments to consider or implement various cost-containment measures, such as price freezes, increased price cuts and rebates, and expanded generic substitution and patient cost-sharing. If budget pressures continue, governments may implement additional cost-containment measures. Regulation Pertaining to Sales and Marketing We are subject to various federal and state laws pertaining to health care “fraud and abuse,” including anti-kickback laws and false claims laws. Anti-kickback laws generally prohibit a prescription drug manufacturer from soliciting, offering, receiving, or paying any remuneration to generate business, including the purchase or prescription of a particular drug. Although the specific provisions of these laws vary, their scope is generally broad and there may be no regulations, guidance or court decisions that clarify how the laws apply to particular industry practices. There is therefore a possibility that our practices might be challenged under the anti-kickback or similar laws. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented for payment to third party payors (including Medicare and Medicaid) claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services. Our activities relating to the sale and marketing of our products may be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal or civil sanctions, including fines and civil monetary penalties, and exclusion from federal health care programs (including Medicare and Medicaid). In the U.S., federal and state authorities are paying increased attention to enforcement of these laws within the pharmaceutical industry and private individuals have been active in alleging violations of the laws and bringing suits on behalf of the government under the federal civil False Claims Act. If we were subject to allegations concerning, or were convicted of violating, these laws, our business could be harmed. 16 Laws and regulations have been enacted by the federal government and various states to regulate the sales and marketing practices of pharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and health care providers or require disclosure to the government and public of such interactions. The laws include federal “sunshine” provisions enacted in 2010 as part of the comprehensive federal health care reform legislation. The sunshine provisions apply to pharmaceutical manufacturers with products reimbursed under certain government programs and require those manufacturers to disclose annually to the federal government (for re-disclosure to the public) certain payments made to physicians and certain other healthcare practitioners or to teaching hospitals. State laws may also require disclosure of pharmaceutical pricing information and marketing expenditures. Many of these laws and regulations contain ambiguous requirements. Given the lack of clarity in laws and their implementation, our reporting actions could be subject to the penalty provisions of the pertinent federal and state laws and regulations. Outside the U.S., other countries have implemented requirements for disclosure of financial interactions with healthcare providers and additional countries may consider or implement such laws. Other Regulations Foreign Anti-Corruption We 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 U.S. 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 political candidate 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 health care professionals we regularly interact with may meet the FCPA's definition of a foreign government official. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequate system of internal accounting controls. The laws to which we are subject also include the U.K. Bribery Act 2010 (Bribery Act) which proscribes giving and receiving bribes in the public and private sectors, bribing a foreign public official, and failing to have adequate procedures to prevent employees and other agents from giving bribes. U.S. companies that conduct business in the United Kingdom generally will be subject to the Bribery Act. Penalties under the Bribery Act include potentially unlimited fines for companies and criminal sanctions for corporate officers under certain circumstances. NIH Guidelines We conduct research at our U.S. facilities in compliance with the current U.S. National Institutes of Health Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines). By local ordinance, we are required to, among other things, comply with the NIH Guidelines in relation to our facilities in Cambridge, Massachusetts and Research Triangle Park (RTP), North Carolina and are required to operate pursuant to certain permits. Other Laws Our present and future business has been and will continue to be subject to various other laws and regulations. Various laws, regulations and recommendations relating to data privacy and protection, safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import, export and use and disposal of hazardous or potentially hazardous substances, including radioactive compounds and infectious disease agents, used in connection with our research work are or may be applicable to our activities. Certain agreements entered into by us involving exclusive license rights may be subject to national or international antitrust regulatory control, the effect of which cannot be predicted. The extent of government regulation, which might result from future legislation or administrative action, cannot accurately be predicted. Environmental Matters We strive to comply in all material respects with applicable laws and regulations concerning the environment. While it is impossible to predict accurately the future costs associated with environmental compliance and potential remediation activities, compliance with environmental laws is not expected to require significant capital expenditures and has not had, and is not expected to have, a material adverse effect on our operations or competitive position. 17 Manufacturing We have three licensed biologics manufacturing facilities, which are located in RTP, North Carolina, Cambridge, Massachusetts, and Hillerød, Denmark. The RTP site includes a 105,000 square foot biologics manufacturing facility, which contains 6,000 (3 x 2,000) liters of bioreactor capacity, as well as a 175,000 square foot Large-Scale Manufacturing (LSM) plant which contains 90,000 (6 x 15,000) liters of bioreactor capacity. The Cambridge site is a 67,000 square foot biologics manufacturing facility that contains 10,000 (5 x 2,000) liters of bioreactor capacity. The Hillerød site is a 228,000 square foot LSM plant that contains 90,000 (6 x 15,000) liters of bioreactor capacity. We rely on our manufacturing facilities in Cambridge, Massachusetts, RTP, North Carolina and Hillerød, Denmark for the production of drug substance for certain of our large molecule products and product candidates. Genentech is responsible for all worldwide manufacturing activities for bulk RITUXAN and GAZYVA and has sourced the manufacture of certain bulk RITUXAN and GAZYVA requirements to a third party. We principally use third parties to manufacture the active pharmaceutical ingredient (API) and the final product for our small molecule products and product candidates, including TECFIDERA and FUMADERM, and the final drug product for our large molecule products and product candidates. Acorda Therapeutics supplies FAMPYRA to us pursuant to its supply agreement with Alkermes, Inc. In December 2012, we entered into an arrangement with Eisai to lease a portion of their facility in RTP to manufacture oral solid dose products supplementing our outsourced small molecule manufacturing capabilities. That facility also manufactures oral solid dose products for Eisai. As part of that arrangement, Eisai may provide us with packaging services for oral solid dose products. In December 2014, we submitted an application to the FDA to approve the manufacture of TECFIDERA 240 mg drug product at this facility. We intend to continue to utilize third party contract manufacturing organizations to manufacture the API and final product for our small molecule products and product candidates, which we intend to supplement through our internal oral solid dose manufacturing capabilities. We source all of our fill-finish and the majority of final product assembly and storage operations for our products, along with a substantial part of our packaging operations, to a concentrated group of third party contract manufacturing organizations. We have internal label and packaging capability for clinical and commercial products at our Cambridge and Hillerød facilities. Raw materials, delivery devices, such as syringes and auto-injectors, and other supplies required for the production of our products and product candidates are procured from various third party suppliers and manufacturers in quantities adequate to meet our needs. Continuity of supply of such raw materials, devices and supplies is assured using a strategy of dual sourcing where possible or by a risk-based inventory strategy. Our third party service providers, suppliers and manufacturers may be subject to routine cGMP inspections by the FDA or comparable agencies in other jurisdictions and undergo assessment and certification by our quality management group. We believe that our manufacturing facilities, together with the third party contract manufacturing organizations we outsource to, currently provide sufficient capacity for our products. We provide contract manufacturing services to Samsung Bioepis, a related party that develops, manufactures and markets biosimilars. We intend to continue to monitor the sufficiency of our manufacturing capacity in light of the development of our product pipeline.

Our current revenues depend upon continued sales of our principal products, TECFIDERA, AVONEX, TYSABRI, and RITUXAN. We may be substantially dependent on sales from our principal products for many years, including an increasing reliance on sales and growth of TECFIDERA as we continue to expand into additional markets. Any negative developments relating to any of these products, including the following, and as discussed in greater detail in these “Risk Factors”, may adversely affect our revenues and results of operations or could cause a decline in our stock price: • • • safety or efficacy issues; the introduction or greater acceptance of competing products; constraints and additional pressures on product pricing or price increases, due to a number of factors, including governmental or regulatory requirements, increased competition, or changes in reimbursement policies and practices of payors and other third parties; or • adverse legal, administrative, regulatory or legislative developments. If we fail to compete effectively, our business and market position would suffer. The biopharmaceutical industry and the markets in which we operate are intensely competitive. We compete in the marketing and sale of our products, the development of new products and processes, the acquisition of rights to new products with commercial potential and the hiring and retention of personnel. We compete with biotechnology and pharmaceutical companies that have a greater number of products on the market and in the product pipeline, greater financial and other resources and other technological or competitive advantages. One or more of our competitors may benefit from significantly greater sales and marketing capabilities, may develop products that are accepted more widely than ours or may receive patent protection that dominates, blocks or adversely affects our product development or business. Our products are also susceptible to competition from generics and biosimilars in many markets. Generic versions of drugs and biosimilars are likely to be sold at substantially lower prices than branded products. Accordingly, the introduction of generic or biosimilar versions of our marketed products likely would significantly reduce both the price that we receive for such marketed products and the volume of products that we sell, which may have an adverse impact on our results of operations. In the MS market, we face intense competition as the number of products and competitors continues to expand. Due to our significant reliance on sales of our MS products, our business may be harmed if we are unable to successfully compete in the MS market. More specifically, our ability to compete and maintain and grow our share in the MS market may be adversely affected due to a number of factors, including: • • • • • the introduction of more efficacious, safer, less expensive or more convenient alternatives to our MS products, including our own products; the introduction of lower-cost biosimilars, follow-on products or generic versions of branded MS products sold by our competitors, and the possibility of future competition from generic versions or related prodrug derivatives or from off- label use by physicians of therapies indicated for other conditions to treat MS patients; patient dynamics, including the size of the patient population and our ability to attract new patients to our therapies; damage to physician and patient confidence in any of our MS products or to our sales and reputation as a result of label changes or adverse experiences or events that may occur with patients treated with our MS products; inability to obtain appropriate pricing and reimbursement for our MS products compared to our competitors in key international markets; or • our ability to obtain and maintain patent, data or market exclusivity for our MS products. Similarly, the hemophilia treatment market is highly competitive, with current treatments marketed by companies that have substantially greater financial resources and marketing expertise. Our ability to successfully compete in the hemophilia market and gain share in this market may be adversely affected due to a number of reasons, including: • difficulty in penetrating this market if our therapies are not regarded as offering substantial benefits over current treatments; 22 • • • • the introduction by other companies of longer-lasting or more efficacious, safer, less expensive or more convenient treatments than our therapies; our limited marketing experience within the hemophilia treatment market, which may impact our ability to develop well- established relationships with the associated medical and scientific community; our failure to receive positive pediatric data from our ongoing global pediatric studies, which is required for filing our planned MAA for ALPROLIX with the EMA; or if one of several companies that are working to develop additional treatments for hemophilia obtains marketing approval of its treatment in the E.U. before we do, our application with the EMA could be barred under operation of the EMA’s Orphan Medicines Regulation. If we are unable to obtain and maintain adequate protection for our data, intellectual property and other proprietary rights, our business may be harmed. Our success depends in part on our ability to obtain and defend patent and other intellectual property rights that are important to the commercialization of our products and product candidates. The degree of patent protection that will be afforded to our products and processes in the U.S. and in other important markets remains uncertain and is dependent upon the scope of protection decided upon by the patent offices, courts and lawmakers in these countries. We can provide no assurance that we will successfully obtain or preserve patent protection for the technologies incorporated into our products and processes, or that the protection obtained will be of sufficient breadth and degree to protect our commercial interests in all countries where we conduct business. If we cannot prevent others from exploiting our inventions, we will not derive the benefit from them that we currently expect. Furthermore, we can provide no assurance that our products will not infringe patents or other intellectual property rights held by third parties. We also rely on regulatory exclusivity for protection of our products. Implementation and enforcement of regulatory exclusivity, which may consist of regulatory data protection and market protection, varies widely from country to country. Failure to qualify for regulatory exclusivity, or failure to obtain or maintain the extent or duration of such protections that we expect in each of the markets for our products, could affect our revenue for our products or our decision on whether to market our products in a particular country or countries or could otherwise have an adverse impact on our results of operations. Litigation, interference, oppositions or other proceedings have been and may in the future be necessary in some instances to determine the validity and scope of certain of our proprietary rights, and in other instances to determine the validity, scope or non-infringement of certain patent rights claimed by third parties to be pertinent to the manufacture, use or sale of our products. We may also face challenges to our patent and regulatory protections covering our products by manufacturers of generics and biosimilars that may choose to launch or attempt to launch their products before the expiration of our patent or regulatory exclusivity. Litigation, interference, oppositions or other similar types of proceedings are unpredictable and may be protracted, expensive and distracting to management. The outcome of such proceedings could adversely affect the validity and scope of our patent or other proprietary rights, hinder our ability to manufacture and market our products, require us to seek a license for the infringed product or technology or result in the assessment of significant monetary damages against us that may exceed amounts, if any, accrued in our financial statements. An adverse determination in a judicial or administrative proceeding or a failure to obtain necessary licenses could prevent us from manufacturing or selling our products. Furthermore, payments under any licenses that we are able to obtain would reduce our profits derived from the covered products and services. 23 Sales of our products depend, to a significant extent, on adequate coverage, pricing and reimbursement from third party payors, which are subject to increasing and intense pressure from political, social, competitive and other sources. Our inability to maintain adequate coverage, or a reduction in pricing or reimbursement, could have an adverse effect on our business, revenues and results of operations, and could cause a decline in our stock price. Sales of our products are dependent, in large part, on the availability and extent of coverage, pricing and reimbursement from government health administration authorities, private health insurers and other organizations, and drug prices are under significant scrutiny in the markets where our products are prescribed. Our ability to set the price for our products can vary significantly from country to country and as a result so can the price of our products, and we may continue to face increasing pressure to lower the prices for our products in many markets. Changes in government regulations or private third-party payors' reimbursement policies, as well as pressure by employers on private health insurance plans to reduce costs, may reduce pricing and reimbursement for our products and adversely affect our future results. In addition, when a new medical product is approved, the availability of government and private reimbursement for that product is uncertain, as is the pricing and amount for which that product will be reimbursed. We also cannot predict the availability, pricing or amount of reimbursement for our product candidates. Our failure to maintain adequate coverage, pricing, or reimbursement for our products would have an adverse effect on our business, revenues and results of operation, could curtail or eliminate our ability to adequately fund research and development programs for the discovery and commercialization of new products, and could cause a decline in our stock price. In the U.S., federal and state legislatures, health agencies and third-party payors continue to focus on containing the cost of health care. Legislative and regulatory proposals and enactments to reform health care insurance programs could significantly influence the manner in which our products are prescribed and purchased. For example, provisions of the PPACA have resulted in changes in the way health care is paid for by both governmental and private insurers, including increased rebates owed by manufacturers under the Medicaid Drug Rebate Program, annual fees and taxes on manufacturers of certain branded prescription drugs, the requirement that manufacturers participate in a discount program for certain outpatient drugs under Medicare Part D and the expansion of the number of hospitals eligible for discounts under Section 340B of the Public Health Service Act. These changes have had and are expected to continue to have a significant impact on our business. Managed care organizations continue to seek price discounts and, in some cases, to impose restrictions on the coverage of particular drugs. For example, health insurers, pharmacy benefit managers and other payors may seek price discounts or rebates in connection with the placement of our products on their formularies. They could also impose restrictions on access to our products, and could even choose to exclude coverage of our products entirely. There is also significant economic pressure on state budgets that may result in states increasingly seeking to achieve budget savings through mechanisms that limit coverage or payment for our drugs. In recent years, some states have considered legislation that would control the prices of drugs, including laws to allow importation of pharmaceutical products from lower cost jurisdictions outside the U.S. State Medicaid programs are increasingly requesting manufacturers to pay supplemental rebates and requiring prior authorization by the state program for use of any drug for which supplemental rebates are not being paid. Government efforts to reduce Medicaid expenses may lead to increased use of managed care organizations by Medicaid programs. This may result in managed care organizations influencing prescription decisions for a larger segment of the population and a corresponding constraint on prices and reimbursement for our products. In addition, under the PPACA, as states implement their health care marketplaces or operate under the federal exchange, the impact on drug manufacturers, including us, will depend in part on the formulary and benefit design decisions made by insurance sponsors or plans participating in these programs. It is possible that we may need to provide discounts or rebates to such plans in order to maintain favorable formulary access for our products for this patient population, which could have an adverse impact on our sales and results of operations. In the European Union and some other international markets, the government provides health care at low cost to consumers and regulates pharmaceutical prices, patient eligibility or reimbursement levels to control costs for the government- sponsored health care system. Many countries have announced or implemented measures to reduce health care costs to constrain their overall level of government expenditures. These measures vary by country and may include, among other things, patient access restrictions, suspensions on price increases, prospective and possibly retroactive price reductions and other recoupments and increased mandatory discounts or rebates, recoveries of past price increases, and greater importation of drugs from lower-cost countries to higher-cost countries. These measures have negatively impacted our revenues, and may continue to adversely affect our revenues and results of operations in the future. In addition, certain countries set prices by reference to the prices in other countries where our products are marketed. Thus, our inability to secure adequate prices in a particular country may not only limit the marketing of our products within that country, but may also adversely affect our ability to obtain acceptable prices in other markets. This may create the opportunity for third party cross-border trade or influence our decision to sell or not to sell a product, thus adversely affecting our geographic expansion plans and revenues. 24 Adverse safety events or restrictions on use and safety warnings for our products can negatively affect our business, product sales and stock price. Adverse safety events involving our marketed products may have a negative impact on our business. Discovery of safety issues with our products could create product liability and could cause additional regulatory scrutiny and requirements for additional labeling, withdrawal of products from the market, and the imposition of fines or criminal penalties. Adverse safety events may also damage physician and patient confidence in our products and our reputation. Any of these could result in liabilities, loss of revenue, material write-offs of inventory, material impairments of intangible assets, goodwill and fixed assets, material restructuring charges and other adverse impacts on our results of operations. Regulatory authorities are making greater amounts of stand-alone safety information directly available to the public through periodic safety update reports, patient registries and other reporting requirements. The reporting of adverse safety events involving our products or products similar to ours and public rumors about such events may increase claims against us and may also cause our product sales or stock price to decline or experience periods of volatility. Restrictions on use or significant safety warnings that may be required to be included in the label of our products, such as the risk of developing progressive multifocal leukoencephalopathy (PML), a serious brain infection, in the label for TYSABRI and in the U.S. label for TECFIDERA, may significantly reduce expected revenues for those products and require significant expense and management time. Our long-term success depends upon the successful development, license or acquisition of new products and additional indications for existing products. Our long-term viability and growth will depend upon the successful development of new products and technologies from our research and development activities, including those licensed or acquired from third parties and biosimilars developed through our joint venture with Samsung Biologics, and approval of additional indications for our existing products. The sustainability of growth in our business is dependent in part upon our ability to continue to build a strong early and mid-stage pipeline of product candidates in our core competencies as well as additional areas of unmet need. Product development is very expensive and involves a high degree of risk. Only a small number of research and development programs result in the commercialization of a product. Success in preclinical work or early stage clinical trials does not ensure that later stage or larger scale clinical trials will be successful or that regulatory approval will be obtained. Further, it is possible that we may experience delays, uncertainties or difficulties developing biosimilars as the legislative and regulatory pathways for approval of biosimilars continue to evolve in many markets. Conducting clinical trials is a complex, time-consuming and expensive process. Our ability to complete our clinical trials in a timely fashion depends in large part on a number of key factors including protocol design, regulatory and institutional review board approval, patient enrollment rates, and compliance with extensive current Good Clinical Practices. We have opened clinical sites and are enrolling patients in a number of countries where our experience is more limited. In most cases, we use the services of third party clinical trial providers and third party contract research organizations, or CROs, to carry out most of our clinical trial related activities and accurately report their results, which may impact our ability to control the timing, conduct, expense and quality of our clinical trials. One CRO has responsibility for substantially all of our clinical trial related activities and reporting. If our CROs do not successfully carry out their activities or meet expected deadlines, our trials may be delayed. We may also need to replace our CROs. Although we believe that there are a number of other third-party CROs we could engage to continue these activities, the replacement of an existing CRO may result in delay of the affected trials or otherwise adversely affect our efforts to obtain regulatory approvals and commercialize our drug candidates. If we fail to adequately manage the design, execution and regulatory aspects of our large, complex and diverse clinical trials, our studies and any potential regulatory approvals may be delayed, or we may fail to gain approvals for our product candidates. Clinical trials may indicate that our product candidates lack efficacy, have harmful side effects or raise safety or other concerns that may significantly reduce the likelihood of regulatory approval, result in significant restrictions on use and safety warnings in the approved label, adversely affect placement within the treatment paradigm, or otherwise significantly diminish the commercial potential of the product candidate. Also, positive results in a registrational trial may not be replicated in any subsequent confirmatory trials. Even if later stage clinical trials are successful, regulatory authorities may disagree with our view of the data or require additional studies, may disagree with trial design or the endpoints employed in the trials, may fail to approve the facilities or the processes used to manufacture a product candidate, may fail to approve or delay approval of our product candidates, dosing or delivery methods, companion devices or may otherwise grant marketing approval that is more restricted than anticipated, including indications covering narrow patient populations and the imposition of safety monitoring or educational requirements or risk evaluation and mitigation strategies. The occurrence of any such events could result in the incurrence of significant costs and expenses, have an adverse effect on our business, including our financial condition and results of operations, or cause our stock price to decline or experience periods of volatility. 25 Even if we are able to successfully develop new products or indications, we may make a strategic decision to discontinue development of such product or indication if, for example, we believe commercialization will be difficult relative to other opportunities in our pipeline. We depend on relationships with collaborators and other third-parties for product and royalty revenue, and the development, commercialization and marketing of certain products, which are outside of our full control. We rely on a number of significant collaborative relationships for product and royalty revenue, and the development, commercialization, and marketing of certain of our products and product candidates. Reliance on collaborative relationships subjects us to a number of risks, including: • we may be unable to control the resources our collaborator devotes to our programs or products; • • • • disputes may arise with respect to ownership of rights to technology developed with our collaboration partner, and the underlying contract with our collaborator may fail to provide significant protection or may fail to be effectively enforced if the collaborator fails to perform; our collaborators’ interests may not always be aligned with our interests and they may not market a product in the same manner or to the same extent that we would, which could adversely affect our revenues; collaborations often require the parties to cooperate, and failure to do so effectively could adversely affect product sales by our collaborators or the clinical development or regulatory approvals of products under joint control or could result in termination of the research, development or commercialization of product candidates or result in litigation or arbitration; and any failure on the part of our collaborators to comply with applicable laws and regulatory requirements in the marketing, sale and maintenance of the market authorization of our products or to fulfill any responsibilities they may have to protect and enforce any intellectual property rights underlying our products could have an adverse effect on our revenues as well as involve us in possible legal proceedings. Given these risks, there is considerable uncertainty regarding the success of our current and future collaborative efforts. If these efforts fail, our product development or commercialization of new products could be delayed or revenues from products could decline. Manufacturing issues could substantially increase our costs, limit supply of our products and reduce our revenues. The process of manufacturing our products is complex, highly regulated and subject to numerous risks, including: • The manufacturing process for our products is extremely susceptible to product loss due to contamination, oxidation, equipment failure or improper installation or operation of equipment, or vendor or operator error. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other supply disruptions. If microbial, viral or other contaminations are discovered in our products or manufacturing facilities, we may need to close our manufacturing facilities for an extended period of time to investigate and remediate the contaminant. • We rely on third party suppliers and manufacturers for, among other things: manufacturing of RITUXAN and GAZYVA; the majority of our clinical and commercial requirements for TECFIDERA and other small molecule products and product candidates; raw materials and supplies for production of products we manufacture; delivery devices such as syringes and auto-injectors; drug product and fill-finish operations; the majority of our final product storage; and a substantial portion of our packaging operations. In addition, due to the unique manner in which our products are manufactured, we rely on single source providers of several raw materials and manufacturing supplies. These third parties are independent entities subject to their own unique operational and financial risks that are outside of our control. These third parties may not perform their obligations in a timely and cost-effective manner or in compliance with applicable regulations, and they may be unable or unwilling to increase production capacity commensurate with demand for our existing or future products. Finding alternative providers could take a significant amount of time and involve significant expense due to the specialized nature of the services and the need to obtain regulatory approval of any significant changes to our suppliers or manufacturing methods. We cannot be certain that we could reach agreement with alternative providers or that the FDA or other regulatory authorities would approve our use of such alternatives. • We rely on our manufacturing facilities in Cambridge, Massachusetts, RTP, North Carolina and Hillerød, Denmark for the production of drug substance for certain of our large molecule products and product candidates, including AVONEX, TYSABRI, PLEGRIDY, ZINBRYTA, ALPROLIX and ELOCTATE. Our global bulk supply of these products and product candidates depends on the uninterrupted and efficient operation of these facilities, which could be adversely affected by equipment failures, labor shortages, natural disasters, power failures and numerous other factors. 26 • We and our third party providers are generally required to maintain compliance with current Good Manufacturing Practices and other stringent requirements and are subject to inspections by the FDA and comparable agencies in other jurisdictions to confirm such compliance. Any delay, interruption or other issues that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or operations of third parties to pass any regulatory agency inspection could significantly impair our ability to develop and commercialize our products. Significant noncompliance could also result in the imposition of monetary penalties or other civil or criminal sanctions and damage our reputation. Any adverse developments affecting our manufacturing operations or the operations of our third-party suppliers and manufacturers may result in shipment delays, inventory shortages, lot failures, product withdrawals or recalls, or other interruptions in the commercial supply of our products. We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet specifications, undertake costly remediation efforts or seek more costly manufacturing alternatives. Such developments could increase our manufacturing costs, cause us to lose revenue or market share as patients and physicians turn to competing therapeutics, diminish our profitability or damage our reputation. While we believe we currently have sufficient manufacturing capacity to meet our near-term manufacturing requirements, it is probable that we would need additional manufacturing capacity to support future clinical and commercial manufacturing requirements for product candidates in our pipeline, if such candidates are successful and approved. Due to the long lead times necessary for the expansion of manufacturing capacity, it is possible that we may incur significant costs to build or acquire additional facilities or obtain third party contract manufacturers in advance of product demand and sales. If we are unable to adequately and timely manufacture and supply our products and product candidates, our business may be harmed. Our business may be adversely affected if we do not manage our current growth and do not successfully execute our growth initiatives. We have experienced significant growth in our headcount and operations, which has placed, and will continue to place, significant demands on our management and our operational and financial infrastructure. We anticipate further growth through both internal development projects as well as external opportunities, which may include the acquisition, partnering and in- licensing of products, technologies and companies or the entry into strategic alliances and collaborations. The availability of high quality development opportunities is limited and competitive, and we are not certain that we will be able to identify candidates that we and our shareholders consider suitable or complete transactions on terms that are acceptable to us and our shareholders. In order to pursue such opportunities, we may require significant additional financing, which may not be available to us on favorable terms, if at all. Even if we are able to successfully identify and complete acquisitions and other strategic alliances and collaborations, we may face unanticipated costs or liabilities in connection with the transaction or we may not be able to integrate them or take full advantage of them or otherwise realize the benefits that we expect. To manage our current and future potential growth effectively, we need to continue to enhance our operational, financial and management processes and to expand, train and manage our employee base. Our growth is also dependent upon our ability to attract and retain qualified scientific, information technology, manufacturing, sales and marketing and executive personnel and to develop and maintain relationships with qualified clinical researchers and key distributors in a highly competitive environment. Supporting our growth initiatives and the further development of our existing products and potential new products in our pipeline will require significant capital expenditures and management resources, including investments in research and development, sales and marketing, manufacturing capabilities and other areas of our business. If we do not successfully manage our current growth and do not successfully execute our growth initiatives, then our business and financial results may be adversely affected and we may incur asset impairment or restructuring charges. If we fail to comply with the extensive legal and regulatory requirements affecting the health care industry, we could face increased costs, penalties and a loss of business. Our activities, and the activities of our collaborators, distributors and other third party providers, are subject to extensive government regulation and oversight both in the U.S. and in foreign jurisdictions. The FDA and comparable agencies in other jurisdictions directly regulate many of our most critical business activities, including the conduct of preclinical and clinical studies, product manufacturing, advertising and promotion, product distribution, adverse event reporting and product risk management. Our interactions in the U.S. or abroad with physicians and other health care providers that prescribe or purchase our products are also subject to government regulation designed to prevent fraud and abuse in the sale and use of the products and place greater restrictions on the marketing practices of health care companies. Health care companies such as ours are facing heightened scrutiny of their relationships with health care providers from anti-corruption enforcement officials. In addition, we along with many other pharmaceutical and biotechnology companies have been the target of lawsuits and investigations alleging violations of government regulation, including claims asserting submission of incorrect pricing information, impermissible off-label promotion of pharmaceutical products, payments intended to influence the referral of health care business, submission of false claims for government reimbursement, antitrust violations, or violations related to 27 environmental matters. These risks may be heightened as we continue to expand our global operations and introduce additional products to the market. Regulations governing the health care industry are subject to change, with possibly retroactive effect, including: • • • • new laws, regulations or judicial decisions, or new interpretations of existing laws, regulations or decisions, related to health care availability, pricing or marketing practices, compliance with wage and hour laws and other employment practices, method of delivery, payment for health care products and services, compliance with health information and data privacy and security laws and regulations, tracking and reporting payments and other transfers of value made to physicians and teaching hospitals, extensive anti-bribery and anti-corruption prohibitions, product serialization and labeling requirements, and used product take-back requirements; changes in the FDA and foreign regulatory approval processes that may delay or prevent the approval of new products and result in lost market opportunity; requirements that provide for increased transparency of clinical trial results and quality data, such as the EMA’s recently enacted clinical transparency policy, which could impact our ability to protect trade secrets and competitively-sensitive information contained in approval applications or could be misinterpreted leading to reputational damage, misperception or legal action which could harm our business; and changes in FDA and foreign regulations that may require additional safety monitoring, labeling changes, restrictions on product distribution or use, or other measures after the introduction of our products to market, which could increase our costs of doing business, adversely affect the future permitted uses of approved products, or otherwise adversely affect the market for our products. Examples of previously enacted and possible future changes in laws that could adversely affect our business include the enactment in the U.S. of health care reform, potential regulations easing the entry of competing biosimilars in the marketplace, new legislation or implementation of existing statutory provisions on importation of lower-cost competing drugs from other jurisdictions, enhanced penalties for and investigations into non-compliance with U.S. fraud and abuse laws, and compliance with the Physician Payment Sunshine Act in the U.S. and similar foreign rules and regulations that require collection and reporting of payments or other transfers of value made to physicians and teaching hospitals. Violations of governmental regulation may be punishable by criminal and civil sanctions against us, including fines and civil monetary penalties and exclusion from participation in government programs, including Medicare and Medicaid, as well as against executives overseeing our business. In addition to penalties for violation of laws and regulations, we could be required to repay amounts we received from government payors, or pay additional rebates and interest if we are found to have miscalculated the pricing information we have submitted to the government. Whether or not we have complied with the law, an investigation into alleged unlawful conduct could increase our expenses, damage our reputation, divert management time and attention and adversely affect our business. A breakdown or breach of our information technology systems could subject us to liability or interrupt the operation of our business. We are increasingly dependent upon information technology systems and data. Our computer systems continue to increase in multitude and complexity due to the growth in our business, making them potentially vulnerable to breakdown, malicious intrusion and random attack. Likewise, data privacy or security breaches by individuals authorized to access our information technology systems or others may pose a risk that sensitive data, including intellectual property, trade secrets or personal information belonging to us, our patients, customers or other business partners, may be exposed to unauthorized persons or to the public. Cyber-attacks are increasing in their frequency, sophistication and intensity. While we continue to build and improve our information systems and infrastructure and believe we have taken appropriate security measures to minimize these risks to our data and information technology systems, there can be no assurance that our efforts will prevent breakdowns or breaches in our systems that could adversely affect our business. Our sales and operations are subject to the risks of doing business internationally. We are increasing our presence in international markets, particularly emerging markets, subjecting us to many risks that could adversely affect our business and revenues, such as: • • • the inability to obtain necessary foreign regulatory or pricing approvals of products in a timely manner; collectability of accounts receivable; fluctuations in foreign currency exchange rates, in particular a strengthening of the U.S. dollar versus foreign currencies; 28 • • • • • • • • • difficulties in staffing and managing international operations; the imposition of governmental controls; less favorable intellectual property or other applicable laws; increasingly complex standards for complying with foreign laws and regulations that may differ substantially from country to country and may conflict with corresponding U.S. laws and regulations; the far-reaching anti-bribery and anti-corruption legislation in the U.K., including the U.K. Bribery Act 2010, and elsewhere and escalation of investigations and prosecutions pursuant to such laws; compliance with complex import and export control laws; restrictions on direct investments by foreign entities and trade restrictions; greater political or economic instability; and changes in tax laws and tariffs. In addition, our international operations are subject to regulation under U.S. law. For example, the Foreign Corrupt Practices Act prohibits U.S. companies and their representatives from offering, promising, authorizing or making payments to foreign officials for the purpose of obtaining or retaining business abroad. In many countries, the health care professionals we regularly interact with may meet the definition of a foreign government official for purposes of the Foreign Corrupt Practices Act. Failure to comply with domestic or foreign laws could result in various adverse consequences, including: possible delay in approval or refusal to approve a product; recalls, seizures or withdrawal of an approved product from the market; disruption in the supply or availability of our products or suspension of export or import privileges; the imposition of civil or criminal sanctions; the prosecution of executives overseeing our international operations; and damage to our reputation. Any significant impairment of our ability to sell products outside of the U.S. could adversely impact our business and financial results. Our effective tax rate may fluctuate and we may incur obligations in tax jurisdictions in excess of accrued amounts. As a global biopharmaceutical company, we are subject to taxation in numerous countries, states and other jurisdictions. As a result, our effective tax rate is derived from a combination of applicable tax rates in the various places that we operate. In preparing our financial statements, we estimate the amount of tax that will become payable in each of such places. Our effective tax rate, however, may be different than experienced in the past due to numerous factors, including changes in the mix of our profitability from country to country, the results of examinations and audits of our tax filings, adjustments to the value of our uncertain tax positions, changes in accounting for income taxes and changes in tax laws. Any of these factors could cause us to experience an effective tax rate significantly different from previous periods or our current expectations. In addition, our inability to secure or sustain acceptable arrangements with tax authorities and previously enacted or future changes in the tax laws, among other things, may result in tax obligations in excess of amounts accrued in our financial statements. In the U.S., there are several proposals under consideration to reform tax law, including proposals that may reduce or eliminate the deferral of U.S. income tax on our unrepatriated earnings, penalize certain transfer pricing structures, and reduce or eliminate certain foreign or domestic tax credits or deductions. Our future reported financial results may be adversely affected by tax law changes which restrict or eliminate certain foreign tax credits or our ability to deduct expenses attributable to foreign earnings, or otherwise affect the treatment of our unrepatriated earnings. In addition to U.S. tax reform proposals, the adoption of some or all of the recommendations set forth in the Organization for Economic Co-operation and Development’s project on “Base Erosion and Profit Shifting” (BEPS) by tax authorities in the countries in which we operate, could negatively impact our effective tax rate. These recommendations focus on payments from affiliates in high tax jurisdictions to affiliates in lower tax jurisdictions and the activities that give rise to a taxable presence in a particular country. 29 Our operating results are subject to significant fluctuations. Our quarterly revenues, expenses and net income (loss) have fluctuated in the past and are likely to fluctuate significantly in the future due to the risks described in these “Risk Factors” as well as the timing of charges and expenses that we may take. We have recorded, or may be required to record, charges that include: • • • • • the cost of restructurings; impairments with respect to investments, fixed assets and long-lived assets, including in-process R&D and other intangible assets; inventory write-downs for failed quality specifications, charges for excess or obsolete inventory and charges for inventory write downs relating to product suspensions, expirations or recalls; bad debt expenses and increased bad debt reserves; outcomes of litigation and other legal or administrative proceedings, regulatory matters and tax matters; • milestone payments under license and collaboration agreements; and • payments in connection with acquisitions and other business development activities. Our revenues are also subject to foreign exchange rate fluctuations due to the global nature of our operations. We recognize foreign currency gains or losses arising from our operations in the period in which we incur those gains or losses. Although we have foreign currency forward contracts to hedge specific forecasted transactions denominated in foreign currencies, our efforts to reduce currency exchange losses may not be successful. As a result, currency fluctuations among our reporting currency, the U.S. dollar, and the currencies in which we do business will affect our operating results, often in unpredictable ways. Our net income may also fluctuate due to the impact of charges we may be required to take with respect to foreign currency hedge transactions. In particular, we may incur higher than expected charges from hedge ineffectiveness or from the termination of a hedge relationship. Our operating results during any one period do not necessarily suggest the anticipated results of future periods. Our investments in properties may not be fully realized. We own or lease real estate primarily consisting of buildings that contain research laboratories, office space, and manufacturing operations. For strategic or other operational reasons, we may decide to further consolidate or co-locate certain aspects of our business operations or dispose of one or more of our properties, some of which may be located in markets that are experiencing high vacancy rates and decreasing property values. If we determine that the fair value of any of our owned properties is lower than their book value we may not realize the full investment in these properties and incur significant impairment charges. If we decide to fully or partially vacate a leased property, such as we did following our 2013 relocation of our corporate headquarters from Weston, Massachusetts to Cambridge, Massachusetts, we may incur significant cost, including lease termination fees, rent expense in excess of sublease income and impairment of leasehold improvements. In addition, in the event we expand our manufacturing capacity and we do not fully utilize our manufacturing facilities, this may result in idle time at facilities or substantial excess manufacturing capacity. Any of these events may have an adverse impact on our results of operations. Our portfolio of marketable securities is subject to market, interest and credit risk that may reduce its value. We maintain a portfolio of marketable securities for investment of our cash. Changes in the value of our portfolio of marketable securities could adversely affect our earnings. In particular, the value of our investments may decline due to increases in interest rates, downgrades of the bonds and other securities included in our portfolio, instability in the global financial markets that reduces the liquidity of securities included in our portfolio, declines in the value of collateral underlying the securities included in our portfolio, and other factors. Each of these events may cause us to record charges to reduce the carrying value of our investment portfolio or sell investments for less than our acquisition cost. Although we attempt to mitigate these risks through diversification of our investments and continuous monitoring of our portfolio's overall risk profile, the value of our investments may nevertheless decline. We may not be able to access the capital and credit markets on terms that are favorable to us. We may seek access to the capital markets to supplement our existing funds and cash generated from operations for working capital, capital expenditure and debt service requirements, and other business initiatives. The capital and credit markets have experienced extreme volatility and disruption which leads to uncertainty and liquidity issues for both borrowers and investors. In the event of adverse capital and credit market conditions, we may be unable to obtain capital market financing 30 on favorable terms. Changes in credit ratings issued by nationally recognized credit rating agencies could adversely affect our cost of financing and have an adverse effect on the market price of our securities. Our business involves environmental risks, which include the cost of compliance and the risk of contamination or injury. Our business and the business of several of our strategic partners involve the controlled use of hazardous materials, chemicals, biologics and radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply with state and federal standards, there will always be the risk of accidental contamination or injury. If we were to become liable for an accident, or if we were to suffer an extended facility shutdown, we could incur significant costs, damages and penalties that could harm our business. Manufacturing of our products and product candidates also requires permits from government agencies for water supply and wastewater discharge. If we do not obtain appropriate permits, or permits for sufficient quantities of water and wastewater, we could incur significant costs and limits on our manufacturing volumes that could harm our business. The illegal distribution and sale by third parties of counterfeit versions of our products or stolen products could have a negative impact on our reputation and business. Third parties might illegally distribute and sell counterfeit or unfit versions of our products, which do not meet our rigorous manufacturing, distribution and testing standards. A patient who receives a counterfeit or unfit drug may be at risk for a number of dangerous health consequences. Our reputation and business could suffer harm as a result of counterfeit or unfit drugs sold under our brand name. In addition, thefts of inventory at warehouses, plants or while in-transit, which are not properly stored and which are sold through unauthorized channels, could adversely impact patient safety, our reputation and our business. The increasing use of social media platforms presents new risks and challenges. Social media is increasingly being used to communicate about our products and the diseases our therapies are designed to treat. Social media practices in the biopharmaceutical industry continue to evolve and regulations relating to such use are not always clear. This evolution creates uncertainty and risk of noncompliance with regulations applicable to our business. For example, patients may use social media channels to comment on the effectiveness of a product or to report an alleged adverse event. When such disclosures occur, there is a risk that we fail to monitor and comply with applicable adverse event reporting obligations or we may not be able to defend the company or the public's legitimate interests in the face of the political and market pressures generated by social media due to restrictions on what we may say about our products. There is also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social networking website. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face overly restrictive regulatory actions or incur other harm to our business. Some of our collaboration agreements contain change in control provisions that may discourage a third party from attempting to acquire us. Some of our collaboration agreements include change in control provisions that could reduce the potential acquisition price an acquirer is willing to pay or discourage a takeover attempt that could be viewed as beneficial to shareholders. Upon a change in control, some of these provisions could trigger reduced milestone, profit or royalty payments to us or give our collaboration partner rights to terminate our collaboration agreement, acquire operational control or force the purchase or sale of the programs that are the subject of the collaboration.

(1) Included in total cost and expenses are charges to acquired in-process research and development (IPR&D) totaling $245.0 million. Of this amount, $205.0 million was incurred in connection with the license agreement entered into with Knopp Neurosciences Inc. (Knopp), which we consolidated as we determined that we were the primary beneficiary of the entity. The $205.0 million charge was partially offset by an attribution of $145.0 million to the noncontrolling interest. We also incurred a charge of $40.0 million in connection with our acquisition of Biogen Idec Hemophilia Inc. (BIH), formerly Syntonix, related to the initiation of patient enrollment in a registrational trial of ALPROLIX. (2) Our share of revenues from unconsolidated joint business reflects charges of $50.0 million in 2011 and $49.7 million in 2013 for damages and interest awarded to Hoechst in Genentech's arbitration with Hoechst for RITUXAN. (3) Biogen Idec Inc.’s shareholders’ equity reflects a reduction in additional paid in capital and noncontrolling interests totaling $187.3 million resulting from our purchase of the noncontrolling interest in our joint venture investments in Biogen Dompé SRL and Biogen Dompé Switzerland GmbH. 35 (4) Commencing in the second quarter of 2013, product and total revenues include 100% of net revenues related to sales of TYSABRI as a result of our acquisition of all remaining rights to TYSABRI from Elan and net revenues related to sales of TECFIDERA. In addition, upon the closing of our acquisition of all remaining rights to TYSABRI, our collaboration agreement was terminated, and we no longer record collaboration profit sharing. 36 Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations The following discussion should be read in conjunction with our consolidated financial statements and related notes beginning on page F-1 of this report. Certain totals may not sum due to rounding. Executive Summary Introduction Biogen Idec is a global biopharmaceutical company focused on discovering, developing, manufacturing and delivering therapies for neurological, autoimmune and hematologic disorders. Our principal marketed products include AVONEX, PLEGRIDY, TECFIDERA, TYSABRI, and FAMPYRA for multiple sclerosis (MS), ALPROLIX for hemophilia B and ELOCTATE for hemophilia A. We also collaborate on the development and commercialization of RITUXAN for the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and other conditions and share profits and losses for GAZYVA which is approved for the treatment of chronic lymphocytic leukemia. Our current revenues depend upon continued sales of our principal products. We may be substantially dependent on sales from our principal products for many years, including an increasing reliance on sales of TECFIDERA as we expand into additional markets. In the longer term, our revenue growth will be dependent upon the successful clinical development, regulatory approval and launch of new commercial products, our ability to obtain and maintain patents and other rights related to our marketed products and assets originating from our research and development efforts, and successful execution of external business development opportunities. As part of our ongoing research and development efforts, we have devoted significant resources to conducting clinical studies to advance the development of new pharmaceutical products and to explore the utility of our existing products in treating disorders beyond those currently approved in their labels. Financial Highlights The following table is a summary of financial results achieved: (In millions, except per share amounts and percentages) Total revenues ............................................................................................... $ Income from operations ................................................................................ $ Net income attributable to Biogen Idec Inc. ................................................. $ Diluted earnings per share attributable to Biogen Idec Inc........................... $ For the Years Ended December 31, 2014 2013 (1) 9,703.3 3,972.4 2,934.8 12.37 $ $ $ $ 6,932.2 2,515.5 1,862.3 7.81 % Change 2014 compared to 2013 40.0% 57.9% 57.6% 58.3% (1) Commencing in the second quarter of 2013, product and total revenues include 100% of net revenues related to TYSABRI as a result of our acquisition of all remaining rights to TYSABRI from Elan and net revenues related to sales of TECFIDERA. As described below under “Results of Operations,” our income from operations for the year ended December 31, 2014, reflect the following: • Worldwide AVONEX revenues totaled $3,013.1 million for 2014, representing an increase of 0.3% over 2013. • Worldwide PLEGRIDY revenues totaled $44.5 million for 2014. • Worldwide TECFIDERA revenues totaled $2,909.2 million for 2014, representing an increase of 232.1% over 2013. • Worldwide TYSABRI revenues totaled $1,959.5 million for 2014, representing an increase of 28.4% over 2013. • Worldwide FAMPYRA revenues totaled $80.2 million for 2014, representing an increase of 8.4% over 2013. • Worldwide ALPROLIX revenues totaled $76.0 million for 2014. • Worldwide ELOCTATE revenues totaled $58.4 million for 2014. • Our share of revenues from unconsolidated joint business totaled $1,195.4 million for 2014, representing an increase of 6.2% from 2013. 37 • Total cost and expenses increased 29.4% for 2014 compared to 2013. This increase resulted from a 42.8% increase in the amortization of acquired intangible assets, a 36.5% increase in cost of sales, a 31.1% increase in research and development expense and a 30.4% increase in selling, general and administrative expense, partially offset by a 100.0% decrease in collaboration profit sharing and an increase in the gain on fair value remeasurement of contingent consideration compared with the same period in 2013. The change in amortization of acquired intangible assets was primarily driven by a $60.2 million increase in amortization of acquired and in-licensed rights and patents as we recognized a full year of expense related to our TYSABRI rights in 2014 versus nine months of expense in 2013, total impairment charges of $50.9 million related to one of our out-licensed patents and one of our in-process research and development intangible assets, and higher amortization of our developed technology intangible asset as a result of lower expected lifetime revenues of AVONEX versus the prior year. The increase in cost of sales was primarily driven by higher unit sales volume, including recent product launches and higher royalty payments due to Elan. The increase in research and development expense was primarily related to an increase in costs incurred in connection with our early stage programs and milestone and upfront payments. Higher selling, general and administrative expense resulted from increased costs incurred in connection with our recent product launches. We generated $2,942.1 million of net cash flows from operations for 2014, which were primarily driven by earnings offset by an increase in working capital. Cash, cash equivalents and marketable securities totaled approximately $3,316.0 million as of December 31, 2014. Business Environment We conduct our business within the biopharmaceutical industry, which is highly competitive. Many of our competitors are working to develop or have commercialized products similar to those we market or are developing. In addition, the commercialization of certain of our own approved MS products and pipeline product candidates may negatively impact future sales of our MS products. Our products may also face increased competitive pressures from the introduction of generic versions, related prodrug derivatives or biosimilars of existing products and other technologies, such as gene therapies. The Patient Protection and Affordable Care Act (PPACA) The PPACA included a significant expansion of the Medicaid program, as well as the creation of new state-based health benefit exchanges, or marketplaces, through which individuals and small businesses may purchase health insurance. Premium and cost-sharing credits and subsidies are available to those who qualify based on income. Marketplace plans began to enroll new members in October 2013, and coverage began on January 1, 2014. Although the effects of the legislation are still unclear, PPACA will result in a greater number of individuals with health insurance under Medicaid and the marketplace health plans. The impact on manufacturers, including us, will depend in part on the formulary and benefit design decisions made by insurance sponsors or plans participating in the programs. It is possible that individuals who were previously unable to access insurance may now become insured, thus increasing coverage for our products. This potential increase in coverage, however, may be offset by the added discounts that could be required in these channels as well as the number of patients who over time move from commercial insurance to the health insurance marketplaces. It is also possible that we may need to provide discounts or rebates to such plans in order to maintain favorable formulary access for our products for this patient population, which could have an adverse impact on our sales and results of operations. During the third quarter of 2014, the Internal Revenue Service issued final regulations related to the Branded Pharmaceutical Drug (BPD) Fee, which had the effect of changing the recognition of the fee for accounting purposes, from the period in which the fee was paid, to the period when the sale occurs. Our products that are subject to the BPD fee include PLEGRIDY, TECFIDERA and TYSABRI, which are recorded in selling, general and administrative expenses, and RITUXAN, which is recorded in unconsolidated joint business. As a result of these final regulations, we recognized an incremental BPD fee of $43.6 million during 2014 for the periods of 2013 and 2014. The final regulations did not change the timing of payments. 38 Results of Operations Revenues Revenues are summarized as follows: (In millions, except percentages) Product Revenues: For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 United States............................................... $ Rest of world...............................................

For 2013 compared to 2012, the increase in U.S. AVONEX revenues was primarily due to price increases, partially offset by a decrease in unit sales volume of 8%, which were attributable in part to patients transitioning to oral therapies including TECFIDERA. For 2014 compared to 2013, the decrease in rest of world AVONEX revenues was due to a 7% decrease in unit demand in Europe primarily attributable to patients transitioning to oral therapies including TECFIDERA, partially offset by a 6% increase in unit demand in the Emerging Markets region. Rest of world AVONEX revenue for 2014 compared to 2013 also reflects the negative impact of foreign currency exchange rate changes experienced in 2014, partially offset by gains recognized in relation to the settlement of certain cash flow hedge instruments under our foreign currency hedging program. For 2013 compared to 2012, the decrease in rest of world AVONEX revenues was primarily due to pricing reductions resulting from austerity measures enacted in some countries, partially offset by increased unit demand primarily in Europe. Rest of world AVONEX revenues for 2013 compared to 2012 also reflects the positive impact of foreign currency exchange rates, partially offset by losses recognized in relation to the settlement of certain cash flow hedge instruments under our foreign currency hedging program. TECFIDERA Revenues from TECFIDERA are summarized as follows: (In millions, except percentages) United States (1).............................................. $ Rest of world (2) ............................................. Total TECFIDERA revenues........................ $ (1) U.S. sales began in the second quarter of 2013. (2) Germany sales began in the first quarter of 2014.

For 2014 compared to 2013, rest of world TECFIDERA revenues increased as sales in Germany began in the first quarter of 2014. We expect that rest of world TECFIDERA revenue will increase as TECFIDERA becomes commercially available in additional markets in 2015. TYSABRI Revenues from TYSABRI are summarized as follows: (In millions, except percentages) United States ................................................... $ Rest of world ................................................... Total TYSABRI revenues............................. $ 2014 2013 2012 1,025.1 934.4 1,959.5 $ $ 814.2 712.3 1,526.5 $ $ 383.1 752.8 1,135.9 For the Years Ended December 31, % Change 2014 compared to 2013 25.9% 31.2% 28.4% 2013 compared to 2012 112.5 % (5.4)% 34.4 % For 2014 compared to 2013, the increase in U.S. TYSABRI revenues was primarily due to price increases and our recognition, starting in April 2013, of 100% of net revenues on TYSABRI in-market sales due to our acquisition of the remaining rights to TYSABRI from Elan, partially offset by a 4% decrease in unit sales volume. For 2013 compared to 2012, the increase in U.S. TYSABRI revenues was primarily due to our acquisition of the remaining rights to TYSABRI from Elan, price increases and a 1% increase in unit sales volume, which includes the impact of patients transitioning to TECFIDERA. Based on data reported by Elan for 2013 and 2012 and our sales to third party customers, total U.S. TYSABRI in-market sales were $958.3 million and $886.0 million for 2013 and 2012, respectively. For 2014 compared to 2013, the increase in U.S. TYSABRI in-market sales was primarily due to price increases, partially offset by patients transitioning to oral therapies including TECFIDERA. For 2013 compared to 2012, the increase in in-market sales was due to price increases. 40 For 2014 compared to 2013, the increase in rest of world TYSABRI revenues was primarily due to the recognition of $53.5 million of revenue previously deferred in Italy relating to the pricing agreement with the Italian National Medicines Agency (Agenzia Italiana del Farmaco or AIFA) as discussed below, volume increases in Europe of 10% and in the Emerging Markets region of 18% and a favorable net price in Germany as the mandatory rebate percentage was reduced. Rest of world TYSABRI revenue for 2014 compared to 2013 also reflects the negative impact of foreign currency exchange rate changes experienced in 2014, partially offset by gains recognized in relation to the settlement of certain cash flow hedge instruments under our foreign currency hedging program. For 2013 compared to 2012, the decrease in rest of world TYSABRI revenues was primarily due to pricing reductions from austerity measures enacted in some countries, a decrease in unit demand primarily in Europe and the net impact of a EUR15.4 million reduction in revenues recorded for a probable settlement of outstanding claims with AIFA relating to sales of TYSABRI in Italy in excess of a reimbursement limit for the periods between February 2009 and January 2011. Rest of world TYSABRI revenues for 2013 compared to 2012 also reflects the positive impact of foreign currency exchange rates, partially offset by losses recognized in relation to the settlement of certain cash flow hedge instruments under our foreign currency hedging program. For information relating to our agreement with AIFA relating to sales of TYSABRI in Italy, please read Note 4, Accounts Receivable to our consolidated financial statements included in this report. As described in Note 4 to our consolidated financial statements, in June 2014, AIFA approved a resolution, effective for a 24 month term, setting the price for TYSABRI in Italy. The resolution also eliminated the reimbursement limit from February 2013 onward. FAMPYRA Revenues from FAMPYRA are summarized as follows: (In millions, except percentages) United States ................................................... $ Rest of world ................................................... Total FAMPYRA revenues........................... $ 2014 2013 2012 — $ 80.2 80.2 $ — $ 74.0 74.0 $ — 57.4 57.4 For the Years Ended December 31, % Change 2014 compared to 2013 2013 compared to 2012 ** 8.4% 8.4% ** 28.9% 28.9% We have a license from Acorda Therapeutics, Inc. (Acorda) to develop and commercialize FAMPYRA in all markets outside the U.S. For information about our relationship with Acorda, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included within this report. For 2014 compared to 2013, the increase in FAMPYRA revenue was primarily due to increased demand, partially offset by the recognition of deferred revenue in the prior year comparative period. For 2013 compared to 2012, the increase in FAMPYRA revenue was due to the recognition of previously deferred revenue and increased demand in Germany and France. FAMPYRA revenue for 2013 includes the recognition of revenues previously deferred in Germany as a result of finalizing a contract that included the final negotiated fixed price, which was higher than the lowest point of the initial range cited by the German pricing authority.

The issuance of the final rule by the Department of Health and Human Services did not have an impact on the amount we recorded as revenues from unconsolidated joint business in our consolidated statements of income because, through June 30, 2013, we had been increasing our share of profits in the U.S. to reflect our interpretation of the proposed 340B rule. The final rule was consistent with our prior interpretation. For 2013 compared to 2012, the increase in U.S. product revenues was due to price increases, an increase in unit sales volume and the $94.9 million recognition in net revenues as discussed above. Collaboration costs and expenses for 2014 compared to 2013 increased primarily due to the recognition of $53.9 million of additional BPD fee expense as well as GAZYVA sales and marketing and research and development expenses. For additional information related to the BPD fee, please read “The Patient Protection and Affordable Care Act (PPACA)” in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Upon the first marketing approval of GAZYVA by the FDA, we began recognizing all activity, including sales and marketing and research and development expenses related to the GAZYVA program in unconsolidated joint business within our consolidated statements of income. Prior to its first regulatory approval, we recognized our share of GAZYVA development and commercialization expenses as research and development expense and selling, general and administrative expense, respectively, within our consolidated statements of income. Collaboration costs and expenses for 2013 compared to 2012 increased primarily due to a higher cost of goods sold resulting from an increased volume in RITUXAN sales, higher associated third party royalties and GAZYVA sales and marketing and research and development expenses. Revenue on Sales in the Rest of World for RITUXAN Revenue on sales in the rest of world for RITUXAN consists of our share of pre-tax co-promotion profits on RITUXAN in Canada and royalty revenue on sales outside the U.S. and Canada. For 2014 compared to 2013, revenue on sales in the rest of world for RITUXAN increased primarily due to the prior year recognition of a $41.2 million charge for damages and interest awarded to Hoechst in its arbitration with Genentech. For 2013 compared to 2012 revenue on sales in the rest of world for RITUXAN decreased as a result of a $41.2 million charge for damages and interest awarded to Hoechst, as discussed above, as well as the expirations of royalties on a country-by-country basis. The royalty period for sales in the rest of world is 11 years from the first commercial sale of such product on a country- by-country basis. The royalty periods for the substantial portion of the royalty-bearing sales in the rest of world markets expired during 2012 and 2013. We expect future revenue on sales of RITUXAN in the rest of world will be limited to our share of pre- tax co-promotion profits in Canada. Other Revenues Other revenues are summarized as follows: (In millions, except percentages) Royalty revenues............................................. $ Corporate partner revenues ............................. Total other revenues...................................... $ Royalty Revenues For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 176.7 127.8 304.5 $ $ 185.7 78.2 263.9 $ $ 168.7 43.8 212.5 (4.8)% 63.4 % 15.4 % 10.1% 78.5% 24.2% We receive royalties from net sales on products related to patents that we licensed. Our most significant source of royalty revenue has been derived from net worldwide sales of ANGIOMAX, which is licensed to The Medicines Company (TMC). In March 2012, the U.S. Patent and Trademark Office granted the extension of the term of the principal U.S. patent that covers ANGIOMAX to December 15, 2014. Royalty revenues from the net worldwide sales of ANGIOMAX are recognized in an amount equal to the level of net sales achieved during a calendar year multiplied by the royalty rate in effect for that tier under our agreement with TMC. The royalty rate increases based upon which tier of total net sales are earned in any calendar year. During 2012, we amended our agreement with TMC for the period from January 1, 2013 to December 15, 2014 to modestly increase the royalty rate in effect for all tiers. 43 For 2014 compared to 2013, royalty revenues decreased due to a decrease in the net worldwide sales of ANGIOMAX subject to royalty payments. For 2013 compared to 2012 the increase in royalty revenues was primarily related to the increase in the royalty rate as well as an increase in the net worldwide sales of ANGIOMAX. Our royalty revenues from ANGIOMAX ceased as of December 15, 2014 upon patent expiry. We also expect declines in royalty revenues from our out-licensed patents over the next several years due to changes in the competitive landscape related to one of the underlying technologies we licensed. These changes resulted in an asset impairment charge of $34.7 million recorded in the first quarter of 2014 which has been reflected in amortization of acquired intangible assets within our consolidated statement of income. As a result, we estimate that in 2015 we will have a decrease of approximately $130 million in royalty revenues. Corporate Partner Revenues Our corporate partner revenues include amounts earned under contract manufacturing agreements, which includes revenues related to our arrangement with Samsung Bioepis, and revenues covering products previously included within our product line that we have sold or exclusively licensed to third parties. For 2014 compared to 2013, the increase in corporate partner revenue was primarily due to higher contract manufacturing revenue and increased revenue from our biosimilar arrangements, partially offset by lower revenue associated with our Zevalin supply agreement. For 2013 compared to 2012, the increase in corporate partner revenues was primarily due to increased revenue from our biosimilar arrangements and an amendment to our Zevalin supply agreement, which resulted in the delivery of our remaining Zevalin inventory and the recognition of a previously deferred amount. Zevalin is a program we sold in 2007 but have continued to manufacture in accordance with the amendment to our Zevalin supply agreement. As part of the amendment, we committed to one additional Zevalin manufacturing campaign, which was completed in the third quarter of 2014. For additional information on our relationship with Samsung Bioepis, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included within this report. Reserves for Discounts and Allowances Revenues from product sales are recorded net of applicable allowances for trade term discounts, wholesaler incentives, Medicaid rebates, Veterans Administration (VA) and Public Health Service (PHS) discounts, specialty pharmacy program fees, managed care rebates, product returns, and other governmental rebates or applicable allowances including those associated with the implementation of pricing actions in certain international markets where we operate. Reserves established for these discounts and allowances are classified as reductions of accounts receivable (if the amount is payable to our customer) or a liability (if the amount is payable to a party other than our customer). These reserves are based on estimates of the amounts earned or to be claimed on the related sales. Our estimates take into consideration our historical experience, current contractual and statutory requirements, specific known market events and trends, and forecasted customer buying and payment patterns. Actual amounts may ultimately differ from our estimates. If actual results vary, we adjust these estimates, which will have an effect on earnings in the period of adjustment. To date, such adjustments have not been significant. Reserves for discounts, contractual adjustments and returns that reduced gross product revenues are summarized as follows: For the Years Ended December 31, (In millions, except percentages) Discounts......................................................... $ Contractual adjustments ..................................

Prior periods included reserves for discounts and allowances for rest of world TYSABRI revenue and worldwide AVONEX revenue. In addition, following our commercial product launches, we began recognizing reserves for discounts and allowances related to these products' revenue. Gross product revenues for the first quarter of 2013 and for 2012 include sales of TYSABRI to Elan under our collaboration agreement, which did not have any corresponding reserves for discounts and allowances. Discounts include trade term discounts and wholesaler incentives. For 2014 compared to 2013, the increase in discounts was primarily driven by our recent product additions. For 2013 compared to 2012, the increase in discounts was primarily driven by the additions of TECFIDERA and U.S. TYSABRI amounts. Contractual adjustments relate to Medicaid and managed care rebates, VA, PHS discounts, specialty pharmacy program fees and other government rebates or applicable allowances. In addition to the above noted product additions, for 2014 compared to 2013, the increase in contractual adjustments was primarily due to an increase in managed care rebates, U.S. governmental rebates and allowances as a result of price increases and additional managed care contracts. For 2013 compared to 2012, the increase in contractual adjustments was primarily due to the additions of TECFIDERA and U.S. TYSABRI amounts and an increase in U.S. governmental rebates and allowances as a result of price increases. Product return reserves are established for returns made by wholesalers. In accordance with contractual terms, wholesalers are permitted to return product for reasons such as damaged or expired product. The majority of wholesaler returns are due to product expiration. Reserves for product returns are recorded in the period the related revenue is recognized, resulting in a reduction to product sales. For 2014 compared to 2013, return reserves increased primarily due to our acquisition of all remaining rights to TYSABRI, the start of commercial sales of TECFIDERA and increased return rates for prior year AVONEX shipments. For 2013 compared to 2012, return reserves increased primarily due to our acquisition of all remaining rights to TYSABRI and the FDA approval and start of commercial sales of TECFIDERA. For additional information related to our reserves, please read Note 5, Reserves for Discounts and Allowances to our consolidated financial statements included within this report.

For 2013 compared to 2012, the increase in product cost of sales was driven by higher unit sales volume, our product launch of TECFIDERA in the U.S. and our biosimilars manufacturing arrangement with Samsung Bioepis. In addition, for 2013 compared to 2012, the increase in product cost of sales was driven by an increase in charges related to excess, obsolete, unmarketable or other inventory due in part to the implementation of our plans to supply rest of world markets with TYSABRI manufactured at our Hillerød, Denmark facility, which was approved by the FDA and EMA in July 2013. Our products are subject to strict quality control and monitoring which we perform throughout the manufacturing process. Periodically, certain batches or units of product may no longer meet quality specifications or may expire. The expiry associated with our inventory is generally between 6 months and 5 years, depending on the product. Inventory amounts written down related to excess, obsolete, unmarketable, or other inventory totaled $50.6 million, $47.3 million, and $24.8 million for the years ended December 31, 2014, 2013, and 2012, respectively. For 2014 compared to 2013 as well as for 2013 compared to 2012, the increase in royalty cost of sales was primarily driven by our acquisition of all remaining rights to TYSABRI, partially offset by the expiration of a third party royalty related to AVONEX. As a result of our acquisition of all remaining rights to TYSABRI from Elan, our contingent payments due to Elan are recorded as a component of royalty cost of sales.

Late stage programs are programs in Phase 3 development or in registration stage. Early stage programs are programs in Phase 1 or Phase 2 development. Research and discovery represents costs incurred to support our discovery research and translational science efforts. Other research and development costs consist of indirect costs incurred in support of overall research and development activities and non-specific programs, including activities that benefit multiple programs, such as management costs as well as depreciation and other facility-based expenses. For several of our programs, the research and development activities are part of our collaborative and other relationships. Our costs reflect our share of the total costs incurred. 46 For 2014 compared to 2013, the increase in research and development expense was primarily related to increase in costs incurred in connection with our early stage programs, upfront and milestone expenses, research and discovery, marketed products and other research and development cost, partially offset by a decrease in costs incurred in connection with our late stage programs. Research and development expense related to our early stage programs increased over the prior year comparative periods primarily due to costs incurred in the advancement of our Anti-LINGO program in MS, our BIIB037 program for Alzheimer’s disease, BAN2401, a program for Alzheimer’s disease related to our collaboration agreement with Eisai and an increase in spending incurred in connection with our development of STX-100 for the treatment of idiopathic pulmonary fibrosis. The increase in spending associated with marketed products is related to ALPROLIX, ELOCTATE and PLEGRIDY, which were recently approved, and costs associated with TYSABRI, which previously were shared with Elan and now are recorded 100% by us upon our acquisition of all remaining rights to TYSABRI from Elan in April 2013. The increase in other research and development costs were related to increased workforce and infrastructure spend in support of core research and development activities. The decrease in spending associated with our late stage product candidates was driven by approvals of ALPROLIX, ELOCTATE and PLEGRIDY in 2014 and GAZYVA in the fourth quarter of 2013, partially offset by costs incurred in the development of ISIS-SMNRx for the treatment of SMA. For 2013 compared to 2012, the increase in research and development expense was primarily related to an increase in costs incurred in connection with our marketed products, early stage programs and upfront and milestone payments partially offset by a decrease in costs incurred in connection with our late stage programs. The increase in spending associated with marketed products is related to TECFIDERA and costs associated with TYSABRI, which previously were shared with Elan. Research and development expense related to our early stage programs increased over the prior year primarily due to costs incurred in the advancement of our Anti-LINGO program in MS, our BIIB037 program for Alzheimer’s disease, our anti- TWEAK program for lupus nephritis, and an increase in spending incurred in connection with our development of STX-100 for the treatment of idiopathic pulmonary fibrosis. The decrease in spending associated with our late stage product candidates was driven by the discontinuation of dexpramipexole, decreased clinical trial activity associated with ELOCTATE and ALPROLIX, which had clinical trials conclude in 2012, and the FDA approval of TECFIDERA in the U.S. during the first quarter of 2013. At the end of December 2012, we learned that a Phase 3 trial investigating dexpramipexole in people with amyotrophic lateral sclerosis (ALS) did not meet its primary endpoint and failed to show efficacy in its key secondary endpoints. Based on these results, we discontinued development of dexpramipexole in ALS. We intend to continue committing significant resources to targeted research and development opportunities where there is a significant unmet need and where the drug candidate has the potential to be highly differentiated. Specifically, we intend to continue to invest in our MS pipeline and in pursuing additional therapies for autoimmune disorders, neurodegenerative diseases and hematologic conditions. Milestone and Upfront Payments included in Research and Development Expense Research and development expense for 2014 includes $139.3 million recorded in connection with our collaboration agreement with Eisai, $25.0 million recorded as milestones in relation to our collaboration agreements with Isis and an aggregate of $60.0 million related to upfront payments made to Sangamo, Google and for other strategic business arrangements. For additional information about these transactions, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included within this report. Included in total research and development expense in 2013 were charges of $75.0 million related to an upfront payment made to Isis in September 2013 upon entering into a six year research collaboration with Isis under which both companies will perform research and then seek to develop and commercialize antisense or other therapeutics for the treatment of neurological disorders, $36.0 million related to upfront and milestone payments made to Samsung Bioepis in December 2013 upon entering into a development and commercialization agreement and a $10.0 million milestone payment made to Isis related to the selection and advancement of ISIS-DMPKRx to treat mytonic dystrophy (DM1). These payments are classified as research and development expense as the programs they relate to have not achieved regulatory approval. Research and development expense in 2012 included charges totaling $71.0 million related to upfront payments made to Isis in January, June and December 2012 upon entering into three separate agreements for the development of Isis’ antisense investigational drug ISIS-SMNRx for the treatment of SMA, product candidates related to the treatment of DM1, and antisense therapeutics for up to three gene targets, respectively. 47 Selling, General and Administrative (In millions, except percentages) Selling, general and administrative ................. $ For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 2,232.3 $ 1,712.1 $ 1,277.5 30.4% 34.0% For 2014 compared to 2013, the increase in selling, general and administrative expenses was primarily driven by costs associated with developing commercial capabilities for our recent product launches along with an increase in sales and marketing activities in support of our MS products. The successful commercialization of new and potential new products requires significant investments, such as sales force build and development, training, marketing, and other related activities. The increase in selling, general, and administrative expense was also driven by an increase in corporate giving and the recognition of $21.9 million of additional BPD fee expense. For additional information related to the BPD fee, please read “The Patient Protection and Affordable Care Act (PPACA)” in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” For 2013 compared to 2012, the increase in selling, general and administrative expense was primarily driven by costs associated with developing commercial capabilities for the product launch of TECFIDERA and the potential product launches of ELOCTATE and ALPROLIX, an increase in sales and marketing activities in support of AVONEX and TYSABRI and the $27.2 million charge recognized in relation to exiting our Weston, Massachusetts facility. For additional information related to this charge, please read Note 11, Property, Plant and Equipment to our consolidated financial statements included in this report. The increase in sales and marketing activities in support of TYSABRI were primarily driven by assuming 100% responsibility of activities as a result of our acquisition of all remaining rights to TYSABRI from Elan. In addition, the increase in selling, general, and administrative expense was driven by an increase in share-based compensation expense, partially offset by a reduction in grant and sponsorship activity. We remain focused on our recent product launches. As discussed above, we continue to invest in commercial capabilities in support of our TECFIDERA program, and we have continued to make investments in the development of commercial capabilities for our hemophilia products. Amortization of Acquired Intangible Assets (In millions, except percentages) Amortization of acquired intangible assets ..... $ For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 489.8 $ 342.9 $ 202.2 42.8% 69.6% For 2014 compared to 2013, the change in amortization of acquired intangible assets was primarily driven by a $60.2 million increase in amortization of acquired and in-licensed rights and patents as we recognized a full year of expense related to our TYSABRI rights in 2014 versus nine months of expense in 2013, total impairment charges of $50.9 million related to one of our out-licensed patents and one of our IPR&D intangible assets, and lower expected lifetime revenues of AVONEX as discussed further below. For additional information related to the amortization of acquired intangible assets, please read Note 7, Intangible Assets and Goodwill to our consolidated financial statements included within this report. For 2013 compared to 2012, the change in amortization of acquired intangible assets was primarily driven by our acquisition of all remaining rights to TYSABRI from Elan and an increase in the amount of amortization recorded in relation to our AVONEX intangible asset. Our amortization expense is based on the economic consumption of the intangible assets. Our most significant intangible assets are related to our AVONEX and TYSABRI products. Annually, during our long-range planning cycle, we perform an analysis of anticipated lifetime revenues of AVONEX and TYSABRI. Our most recent long range planning cycle was updated in the third quarter of 2014. Our analysis included an increase in the expected future product revenues of TYSABRI, resulting in a decrease in amortization expense as compared to prior quarters. Our analysis also included a decrease in the expected future product revenues of AVONEX, resulting in an increase in amortization expense as compared to prior quarters. The results of our TYSABRI and AVONEX analyses were impacted by changes in the estimated impact of TECFIDERA, as well as other existing and potential oral and alternative MS formulations, including PLEGRIDY, that may compete with TYSABRI and AVONEX. Based upon this more recent analysis, the estimated future amortization for acquired intangible assets is expected to be as follows: 48 (In millions) 2015 .......................................................................................................................................................... $ 2016 .......................................................................................................................................................... 2017 .......................................................................................................................................................... 2018 .......................................................................................................................................................... 2019 .......................................................................................................................................................... As of December 31, 2014 344.3 313.2 286.3 283.7 273.6 Total ..................................................................................................................................................... $ 1,501.1 We monitor events and expectations regarding product performance. If there are any indications that the assumptions underlying our most recent analysis would be different than those utilized within our current estimates, our analysis would be updated and may result in a significant change in the anticipated lifetime revenues of the relevant process. The occurrence of an adverse event could substantially increase the amount of amortization expense associated with our acquired intangible assets as compared to previous periods or our current expectations, which may result in a significant negative impact on our future results of operations. Impairment of Intangible Assets We record charges associated with impairments of intangible assets in amortization of intangible assets. The field of developing idiopathic pulmonary fibrosis (IPF) treatments is highly competitive and characterized by rapid technological advances as two of our competitors filed marketing applications during the second quarter of 2014, seeking approval for potentially competitive treatment regimens. There can be no assurance that we will be able to successfully develop STX-100 for the treatment of IPF (STX-100 in IPF). During the second quarter of 2014, we determined that there were indicators that the value of the STX-100 in IPF intangible asset may have become impaired. As a result of our impairment testing, we determined that no impairment was required. During 2014, we recorded a charge of $34.7 million related to the impairment of one of our out-licensed patents to reflect a change in its estimated fair value, due to a change in the underlying competitive market for that product, which occurred during the first quarter of 2014. During the third quarter of 2014, we updated the probabilities of success related to the early stage programs acquired through our recent acquisitions. This change in probability of success, combined with a delay in one of the projects, resulted in an impairment loss of $16.2 million. For additional information, please read Note 7, Intangible Assets and Goodwill to our consolidated financial statements included within this report. Overall, the value of our acquired IPR&D assets is dependent upon a number of variables, including estimates of future revenues and the effects of competition, the level of anticipated development costs and the probability and timing of successfully advancing a particular research program from a clinical trial phase to the next. We are continually reevaluating our estimates concerning these variables and evaluating industry data regarding the productivity of clinical research and the development process. Changes in our estimates of items may result in a significant change to our valuation of these assets. Collaboration Profit Sharing (In millions, except percentages) Collaboration profit sharing ............................ $ 2014 2013 2012 — $ 85.4 $ 317.9 For the Years Ended December 31, % Change 2014 compared to 2013 (100.0)% 2013 compared to 2012 (73.1)% Upon the closing of our acquisition of all remaining rights to TYSABRI, our collaboration agreement was terminated, and we no longer record collaboration profit sharing. Collaboration profit sharing previously included the portion of rest of world net operating profits to be shared with Elan under the terms of our collaboration agreement for the development, manufacture and commercialization of TYSABRI. The amount also included the reimbursement for our portion of third-party royalties paid by Elan on behalf of the collaboration relating to rest of world sales. For 2012, our collaboration profit sharing expense included $53.2 million related to the reimbursement of third-party royalty payments made by Elan, which started to expire in 2013. For additional information about this collaboration, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included in this report. 49 (Gain) Loss on Fair Value Remeasurement of Contingent Consideration (In millions, except percentages) (Gain) loss on fair value remeasurement of contingent consideration ................................. $ For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 (38.9) $ (0.5) $ 27.2 ** (102.0)% The consideration for certain of our business combinations includes future payments that are contingent upon the occurrence of a particular factor or factors. For business combinations completed after January 1, 2009, we record an obligation for such contingent consideration payments at its fair value on the acquisition date. We revalue our contingent consideration obligations each reporting period. Changes in the fair value of our contingent consideration obligations, other than changes due to payments, are recognized as a (gain) loss on fair value remeasurement of contingent consideration within our consolidated statements of income. The increase in the gain for 2014 was primarily due to an adjustment to the value of our contingent consideration liabilities as we updated the probabilities of success related to the early stage programs acquired through our recent acquisitions. For additional information, please read Note 7, Intangible Assets and Goodwill to our consolidated financial statements included within this report. Gain on Sale of Rights (In millions, except percentages) Gain on sale of rights ...................................... $ 2014 2013 2012 16.8 $ 24.9 $ 46.8 For the Years Ended December 31, % Change 2014 compared to 2013 (32.7)% 2013 compared to 2012 (46.8)% During the third quarter of 2012, we sold all of our rights, including rights to royalties, related to BENLYSTA (belimumab) to a DRI Capital managed fund (DRI). Under the terms of the BENLYSTA sale agreement, we received payments from DRI equal to a multiple of royalties payable by the Human Genome Sciences, Inc. and GlaxoSmithKline plc for the period covering October 2011 to September 2014 and a one-time contingency payment that could be paid to us if the cumulative royalties over the full royalty term exceed an agreed amount. For 2014 compared to 2013, we recognized lower payments from the sale of our rights to BENLYSTA resulting from a lower multiple of sales being applied in 2014 as compared to 2013. For 2013 compared to 2012, we recognized lower payments from the sale of our rights to BENLYSTA resulting from a lower multiple of sales being applied in 2013 as compared to 2012. As the period under which we would receive royalties expired in September 2014, we will not receive any additional payments under this agreement. For additional information related to this transaction, please read Note 3, Gain on Sale of Rights to our consolidated financial statements included in this report. Other Income (Expense), Net (In millions, except percentages) Other income (expense), net ........................... $ 2014 2013 2012 (25.8) $ (34.9) $ (0.7) For the Years Ended December 31, % Change 2014 compared to 2013 (26.2)% 2013 compared to 2012 ** For 2014 compared to 2013, the change in other income (expense), net was due to lower non-income based state taxes, an increase in interest income due to higher average cash, cash equivalents and marketable securities balances, lower foreign exchange losses and decreased interest expense as we repaid our 6.0% Senior Notes in March 2013, partially offset by lower gains on investments. For 2013 compared to 2012, the change in other income (expense), net was due to a decrease in interest income due to lower average cash, cash equivalent and marketable securities balances primarily related to the use of cash in connection with our acquisition of all remaining rights to TYSABRI from Elan and the repayment of our 6.0% Senior Notes, a decrease in other, net primarily related to higher non-income based state taxes and higher foreign exchange losses. Other income (expense), net in 2012 includes a gain of $9.0 million recognized upon our acquisition of Stromedix in March 2012, which was based on the value derived from the purchase price of our equity interest held in Stromedix prior to the acquisition. For additional information related to our strategic investments, please read Note 9, Financial Instruments to our consolidated financial statements included in this report. 50 Income Tax Provision (In millions, except percentages) Effective tax rate on pre-tax income ............... Income tax expense ......................................... $ For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 25.1% 989.9 $ 24.2% 601.0 $ 25.4% 470.6 3.7% 64.7% (4.7)% 27.7 % Our effective tax rate fluctuates from year to year due to the global nature of our operations. The factors that most significantly impact our effective tax rate include variability in the allocation of our taxable earnings among multiple jurisdictions, changes in tax laws, the amount and characterization of our research and development expenses, the levels of certain deductions and credits, acquisitions, and licensing transactions. Our effective tax rate for 2014 compared to 2013 increased primarily as a result of the absence of a benefit related to the 2013 change in our uncertain tax position related to our U.S. federal manufacturing deduction and our unconsolidated joint business described below under "Accounting for Uncertainty in Income Taxes", lower current year expenses eligible for the orphan drug credit and a lower relative manufacturing deduction due to unqualified products, partially offset by a higher percentage of our 2014 income being earned outside the U.S. Our effective tax rate for 2013 compared to 2012 decreased primarily as a result of a change in our uncertain tax position related to our U.S. federal manufacturing deduction and our unconsolidated joint business, described below under "Accounting for Uncertainty in Income Taxes", lower intercompany royalties owed by a foreign wholly owned subsidiary to a U.S. wholly owned subsidiary on the international sales of one of our products, the reinstatement of the federal research and development tax credit and the 2012 correction of an error in our deferred tax accounting, which increased our rate in the prior year. These favorable items were partially offset by higher relative earnings in the U.S. from the commercial launch of TECFIDERA, lower orphan drug credits due to reduced expenditures in eligible clinical trials and higher state taxes. Accounting for Uncertainty in Income Taxes During 2013, we received updated technical guidance from the IRS concerning the calculation of our U.S. federal manufacturing deduction and overall tax classification of our unconsolidated joint business for the current and prior year filings. Based on this guidance we reevaluated the level of our unrecognized benefits related to uncertain tax positions and recorded a $49.8 million income tax benefit. This benefit was for a previously unrecognized position and related to years 2005 through 2012. We recorded an offsetting expense of $11.3 million for non-income based state taxes, which was recorded in other income (expense) within our consolidated statements of income. For more information on our uncertain tax positions and income tax rate reconciliation for 2014, 2013 and 2012, please read Note 17, Income Taxes to our consolidated financial statements included in this report. Equity in Loss of Investee, Net of Tax (In millions, except percentages) Equity in loss of investee, net of tax ............... $ 2014 2013 2012 15.1 $ 17.2 $ 4.5 For the Years Ended December 31, % Change 2014 compared to 2013 (12.2)% 2013 compared to 2012 281.2% In February 2012, we entered into an agreement with Samsung BioLogics Co. Ltd., establishing an entity, Samsung Bioepis, to develop, manufacture and market biosimilar pharmaceuticals. We account for this investment under the equity method of accounting. We recognize our share of the results of operations related to our investment in Samsung Bioepis one quarter in arrears. For 2014 compared to 2013, the decrease in equity in loss of investee, net of tax was due to the joint venture's clinical trial activity, partially offset by our recognition of a gain as Samsung Bioepis secured additional equity financing from Samsung Biologics from a financing in which we did participate. For 2013 compared to 2012, the increase in equity in loss of investee, net of tax was due to increased clinical trial activity. For additional information related to this transaction, please read Note 20, Collaborative and Other Relationships to our consolidated financial statements included in this report. 51 Noncontrolling Interest (In millions, except percentages) Net income attributable to noncontrolling interests, net of tax .......................................... $ For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 6.8 $ — $ — ** ** For 2014 compared to 2013, the change in net income attributable to noncontrolling interests, net of tax, was related to a $10.0 million milestone payment made to Neurimmune and the consolidation of the research activities of Ataxion. For additional information about these transactions, please read Note 19, Investments in Variable Interest Entities to our consolidated financial statements included within this report. Market Risk We conduct business globally. As a result, our operations are subject to certain risks which may affect our results of operations, including volatility in foreign currency exchange rates or weak economic conditions in the foreign markets in which we operate, and pricing pressures worldwide. In addition, our results of operations and the fair value of our asset and liabilities may be impacted by interest rate movements. Foreign Currency Exchange Risk Our results of operations are subject to foreign currency exchange rate fluctuations due to the global nature of our operations. We have operations or maintain distribution relationships in the U.S., Europe, Canada, Australia, New Zealand, Japan and Central and South America. In addition, we receive royalty revenues based on worldwide product sales by our licensees and through Genentech on sales of RITUXAN in the rest of world. As a result, our financial position, results of operations and cash flows can be affected by market fluctuations in foreign exchange rates, primarily with respect to the Euro, Canadian dollar, Danish krone, Swiss franc, Japanese yen, Australian dollar and British pound. While the financial results of our global activities are reported in U.S. dollars, the functional currency for most of our foreign subsidiaries is their respective local currency. Fluctuations in the foreign currency exchange rates of the countries in which we do business will affect our operating results, often in ways that are difficult to predict. In particular, as the U.S. dollar strengthens versus other currencies the value of the non-U.S. revenue will decline when reported in U.S. dollars. The impact to net income as a result of a U.S. dollar strengthening will be partially mitigated by the value of non-U.S. expense which will also decline when reported in U.S. dollars. As the U.S. dollar weakens versus other currencies the value of the non-U.S. revenue and expenses will increase when reported in U.S. dollars. We have established revenue hedging and balance sheet risk management programs to protect against volatility of future foreign currency cash flows and changes in fair value caused by volatility in foreign exchange rates. Revenue Hedging Program Our foreign currency hedging program is designed to mitigate, over time, a portion of the impact resulting from volatility in exchange rate changes on revenues. We use foreign currency forward contracts to manage foreign currency risk with the majority of our forward contracts used to hedge certain forecasted revenue transactions denominated in foreign currencies in the next 15 months. We do not engage in currency speculation. For a more detailed disclosure of our revenue hedging program, please read Note 10, Derivative Instruments to our consolidated financial statements included in this report. Our ability to mitigate the impact of exchange rate changes on revenues and net income diminishes as significant exchange rate fluctuations are sustained over extended periods of time. In particular, devaluation or significant deterioration of foreign currency exchange rates are difficult to mitigate and likely to negatively impact earnings. The cash flows from these contracts are reported as operating activities in our consolidated statements of cash flows. Balance Sheet Risk Management Hedging Program We also use forward contracts to mitigate the foreign currency exposure related to certain balance sheet items. The primary objective of our balance sheet risk management program is to mitigate the exposure of foreign currency denominated net monetary assets of foreign affiliates. In these instances, we principally utilize currency forward contracts. We have not elected hedge accounting for the balance sheet related items. The cash flows from these contracts are reported as operating activities in the consolidated statement of cash flows. 52 Quantitative and Qualitative Disclosures About Market Risk The following quantitative information includes the impact of currency movements on forward contracts used in both our revenue and balance sheet hedging programs. As of December 31, 2014 and 2013, a hypothetical adverse 10% movement in foreign currency rates compared to the U.S. dollar across all maturities would result in a hypothetical decrease in the fair value of forward contracts of approximately $160.0 million and $102.0 million, respectively. The estimated fair value change was determined by measuring the impact of the hypothetical exchange rate movement on outstanding forward contracts. Our use of this methodology to quantify the market risk of such instruments is subject to assumptions and actual impact could be significantly different. The quantitative information about market risk is limited because it does not take into account all foreign currency operating transactions. Interest Rate Risk Our investment portfolio includes cash equivalents and short-term investments. The fair value of our marketable securities is subject to change as a result of potential changes in market interest rates. The potential change in fair value for interest rate sensitive instruments has been assessed on a hypothetical 100 basis point adverse movement across all maturities. As of December 31, 2014 and 2013, we estimate that such hypothetical adverse 100 basis point movement would result in a hypothetical loss in fair value of approximately $14.5 million and $5.7 million, respectively, to our interest rate sensitive instruments. The fair values of our investments were determined using a combination of pricing and duration models. Pricing Pressure Governments in some international markets in which we operate have implemented measures aimed at reducing healthcare costs to constrain the overall level of government expenditures. These implemented measures vary by country and include, among other things, mandatory rebates and discounts, prospective and possible retroactive price reductions and suspensions on pricing increases on pharmaceuticals. In addition, certain countries set prices by reference to the prices in other countries where our products are marketed. Thus, our inability to secure adequate prices in a particular country may impair our ability to obtain acceptable prices in existing and potential new markets and limit market growth. The continued implementation of pricing actions throughout Europe may also lead to higher levels of parallel trade. In the U.S., federal and state legislatures, health agencies and third-party payors continue to focus on containing the cost of health care. Legislative and regulatory proposals and enactments to reform health care insurance programs could significantly influence the manner in which our products are prescribed and purchased. It is possible that additional federal health care reform measures will be adopted in the future, which could result in increased pricing pressure and reduced reimbursement for our products and otherwise have an adverse impact on our financial position or results of operations. There is also significant economic pressure on state budgets that may result in states increasingly seeking to achieve budget savings through mechanisms that limit coverage or payment for our drugs. Managed care organizations are also continuing to seek price discounts and, in some cases, to impose restrictions on the coverage of particular drugs. Credit Risk We are subject to credit risk from our accounts receivable related to our product sales. The majority of our accounts receivable arise from product sales in the U.S. and Europe with concentrations of credit risk limited due to the wide variety of customers and markets using our products, as well as their dispersion across many different geographic areas. Our accounts receivable are primarily due from wholesale distributors, public hospitals and other government entities. We monitor the financial performance and creditworthiness of our large customers so that we can properly assess and respond to changes in their credit profile. We operate in certain countries where weakness in economic conditions has resulted in extended collection periods. We continue to monitor these conditions, including the volatility associated with international economies and the relevant financial markets, and assess their possible impact on our business. Our historical write-offs of accounts receivable have not been significant. Within the European Union, our accounts receivable in Spain, Italy and Portugal continue to be subject to significant payment delays due to government funding and reimbursement practices. Uncertain credit and economic conditions have generally led to greater collection risk, although these countries have introduced various programs periodically to pay down significantly overdue payables. Please refer to Note 4, Accounts Receivable to our consolidated financial statements included within this report for further details on recent payments and classification. 53 We believe that our allowance for doubtful accounts was adequate as of December 31, 2014 and 2013, respectively. However, if significant changes occur in the availability of government funding or the reimbursement practices of these or other governments, we may not be able to collect on amounts due to us from customers in such countries and our results of operations could be adversely affected. Financial Condition, Liquidity and Capital Resources Our financial condition is summarized as follows: (In millions, except percentages) Financial assets: As of December 31, 2014 2013 % Change 2014 compared to 2013 Cash and cash equivalents ....................................................................... $ Marketable securities — current.............................................................. Marketable securities — non-current.......................................................

For the year ended December 31, 2013, certain significant cash flows were as follows: • • • • • • $3.25 billion used for our acquisition of all remaining rights to TYSABRI from Elan; $643.2 million in total payments for income taxes; $450.0 million used for the repayment of principal of our 6.0% Senior Notes; $400.3 million used for share repurchases; $246.3 million used for purchases of property, plant and equipment; and $100.0 million upfront payment made to Isis pursuant to our collaboration agreement dated September 2013. We have historically financed our operating and capital expenditures primarily through cash flows earned through our operations. We expect to continue funding our current and planned operating requirements principally through our cash flows from operations, as well as our existing cash resources. We believe that our existing funds, when combined with cash generated from operations and our access to additional financing resources, if needed, are sufficient to satisfy our operating, working capital, strategic alliance, milestone payment, capital expenditure and debt service requirements for the foreseeable future. In addition, we may choose to opportunistically return cash to shareholders and pursue other business initiatives, including acquisition and licensing activities. We may, from time to time, also seek additional funding through a combination of new 54 collaborative agreements, strategic alliances and additional equity and debt financings or from other sources should we identify a significant new opportunity. The undistributed cumulative foreign earnings of certain of our foreign subsidiaries, exclusive of earnings that would result in little or no net income tax expense under current U.S. tax law or which has already been subject to tax under U.S. tax law, are invested indefinitely outside the U.S. Of the total cash, cash equivalents and marketable securities at December 31, 2014, approximately $1,755 million was generated in foreign jurisdictions and is primarily intended for use in our foreign operations or in connection with business development transactions outside of the U.S. In managing our day-to-day liquidity in the U.S., we do not rely on the unrepatriated earnings as a source of funds and we have not provided for U.S. federal or state income taxes on these undistributed foreign earnings. For additional information related to certain risks that could negatively impact our financial position or future results of operations, please read the “Risk Factors” and “Quantitative and Qualitative Disclosures About Market Risk” sections of this report. Share Repurchase Programs In February 2011, our Board of Directors authorized the repurchase of up to 20.0 million shares of common stock. This authorization does not have an expiration date. In 2014, approximately 2.9 million shares were repurchased at a cost of $886.8 million. As of December 31, 2014, approximately 1.3 million shares of our common stock remained available for repurchase under the 2011 authorization. We repurchased approximately 2.0 million shares at a cost of approximately $400.3 million under the 2011 authorization in 2013. Cash, Cash Equivalents and Marketable Securities Until required for another use in our business, we typically invest our cash reserves in bank deposits, certificates of deposit, commercial paper, corporate notes, U.S. and foreign government instruments and other interest bearing marketable debt instruments in accordance with our investment policy. It is our policy to mitigate credit risk in our cash reserves and marketable securities by maintaining a well-diversified portfolio that limits the amount of exposure as to institution, maturity, and investment type. We also limit our exposure to European sovereign debt securities and maintain no holdings with respect to certain euro-zone states, such as Portugal, Italy and Spain. The value of our investments, however, may be adversely affected by increases in interest rates, downgrades in the credit rating of the corporate bonds included in our portfolio, instability in the global financial markets that reduces the liquidity of securities included in our portfolio, and by other factors which may result in declines in the value of the investments. Each of these events may cause us to record charges to reduce the carrying value of our investment portfolio if the declines are other-than-temporary or sell investments for less than our acquisition cost which could adversely impact our financial position and our overall liquidity. The increase in cash, cash equivalents and marketable securities from December 31, 2013 is primarily due to net cash flows provided by operating activities, partially offset by the repurchase of our common stock. Borrowings In March 2014, our $750.0 million senior unsecured revolving credit facility expired and was not renewed. We have $550.0 million aggregate principal amount of 6.875% Senior Notes due March 1, 2018 that were originally priced at 99.184% of par. The discount is amortized as additional interest expense over the period from issuance through maturity. In connection with our 2006 distribution agreement with Fumedica, we issued notes totaling 61.4 million Swiss Francs which were payable to Fumedica in varying amounts from June 2008 through June 2018. Our remaining note payable to Fumedica had a carrying value of 11.6 million Swiss Francs ($11.7 million) and 14.0 million Swiss Francs ($15.8 million) as of December 31, 2014 and 2013, respectively. For a summary of the fair and carrying values of our outstanding borrowings as of December 31, 2014 and 2013, please read Note 8, Fair Value Measurements to our consolidated financial statements included in this report. 55 Working Capital We define working capital as current assets less current liabilities. The increase in working capital from December 31, 2013 reflects an increase in total current assets of $1,487.8 million, partially offset by an increase in total current liabilities of $461.4 million. The increase in total current assets was primarily driven by an increase in cash and cash equivalents and accounts receivable resulting from increased product revenue. The increase in total current liabilities primarily resulted from an increase in accrued expenses and other. Cash Flows The following table summarizes our cash flow activity: (In millions, except percentages) Net cash flows provided by operating activities .......................................................... $ Net cash flows used in by investing activities $ Net cash flows used in financing activities ..... $ Operating Activities For the Years Ended December 31, 2014 2013 2012 % Change 2014 compared to 2013 2013 compared to 2012 2,942.1 $ (1,543.0) $ (755.9) $ $ 2,345.1 (1,604.7) $ (716.5) $ 1,879.9 (950.3) (877.5) 25.5 % (3.8)% 5.5 % 24.7 % 68.9 % (18.3)% Cash flows from operating activities represent the cash receipts and disbursements related to all of our activities other than investing and financing activities. We expect cash provided from operating activities will continue to be our primary source of funds to finance operating needs and capital expenditures for the foreseeable future. Operating cash flow is derived by adjusting our net income for: • Non-cash operating items such as depreciation and amortization, impairment charges and share-based compensation charges; • Changes in operating assets and liabilities which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in results of operations; and • Changes associated with the fair value of contingent milestones associated with our acquisitions of businesses and payments related to collaborations. For 2014 compared to 2013, the increase in cash provided by operating activities is primarily driven by higher net income, partially offset by an increase in accounts receivable resulting from increased product revenue For 2013 compared to 2012, the increase in cash provided by operating activities was primarily driven by an increase in net income and taxes payable, partially offset by an increase in inventory related to our AVONEX, TYSABRI and ELOCTATE programs and accounts receivable resulting from increased product revenue. Investing Activities For 2014 compared to 2013, the decrease in net cash flows used in investing activities is primarily due to the prior year acquisition of all remaining rights to TYSABRI from Elan and a decrease in the net purchases of marketable securities, partially offset by the payment of contingent consideration to former shareholders of Fumapharm AG. For 2013 compared to 2012, the increase in net cash flows used in investing activities was primarily due to $3,262.7 million used for our acquisition of all remaining rights to TYSABRI from Elan, partially offset by net proceeds from sales and maturities of marketable securities. Financing Activities For 2014 compared to 2013, the increase in net cash flows used in financing activities is primarily due to an increase in the amount of common stock we repurchased, partially offset by the prior year repayment of the aggregate principal amount of our 6.0% Senior Notes. For 2013 compared to 2012, the decrease in net cash flows used in financing activities was primarily due to a decrease in the amount of our common stock we repurchased partially offset by the repayment of principal of our 6.0% Senior Notes. 56 Contractual Obligations and Off-Balance Sheet Arrangements Contractual Obligations The following table summarizes our contractual obligations as of December 31, 2014, excluding amounts related to uncertain tax positions, amounts payable to tax authorities, funding commitments, contingent development, regulatory and commercial milestone payments, TYSABRI contingent payments and contingent consideration related to our business combinations, as described below. (In millions) Non-cancellable operating leases (1), (2) ....... $ Notes payable (3)............................................ Purchase and other obligations (4) ................. Defined benefit obligation .............................. Total contractual obligations ........................ $ Total 675.7 681.5 248.9 56.7 1,662.8 $ $ Less than 1 Year Payments Due by Period 1 to 3 Years 3 to 5 Years After 5 Years 62.2 40.9 238.6 — 341.7 $ $ 129.4 81.4 10.3 — 221.1 $ $ 108.0 559.2 — — 667.2 $ $ 376.1 — — 56.7 432.8 (1) We lease properties and equipment for use in our operations. Amounts reflected within the table above, detail future minimum rental commitments under non-cancelable operating leases as of December 31 for each of the periods presented. In addition to the minimum rental commitments, these leases may require us to pay additional amounts for taxes, insurance, maintenance and other operating expenses. (2) Obligations are presented net of sublease income expected to be received for the vacated portion of our Weston, Massachusetts facility. For additional information, please read Note 11, Property, Plant and Equipment to our consolidated financial statements included in this report. (3) Notes payable includes principal and interest payments. (4) Purchase and other obligations primarily includes our obligations to purchase direct materials and also includes approximately $5.4 million related to the fair value of net liabilities on derivative contracts, approximately $8.1 million related to fixed obligations for the purchase of natural gas and approximately $11.8 million related to obligations for communication services. Tax Related Obligations We exclude liabilities pertaining to uncertain tax positions from our summary of contractual obligations as we cannot make a reliable estimate of the period of cash settlement with the respective taxing authorities. As of December 31, 2014, we have approximately $80.2 million of net liabilities associated with uncertain tax positions. Other Funding Commitments As of December 31, 2014, we have several on-going clinical studies in various clinical trial stages. Our most significant clinical trial expenditures are to contract research organizations (CROs). The contracts with CROs are generally cancellable, with notice, at our option. We have recorded accrued expenses of approximately $41.6 million on our consolidated balance sheet for expenditures incurred by CROs as of December 31, 2014. We have approximately $472.3 million in cancellable future commitments based on existing CRO contracts as of December 31, 2014. World Federation of Hemophilia (WFH) Humanitarian Aid Program During 2014, we and Sobi announced plans to donate one billion international units (IUs) of clotting factor therapy for humanitarian aid programs in the developing world. Initially, we intend to donate up to 500 million IUs over five years to support these efforts through the WFH. Under the terms of the agreement, at least 85 percent of donated factor will be ELOCTATE, with the remainder comprised of ALPROLIX. These shipments for humanitarian programs are expected to begin in the second half of 2015, subject to the WFH satisfying certain logistical and ongoing requirements. We will record these donations as cost of sales as the donations are made. 57 Contingent Development, Regulatory and Commercial Milestone Payments Based on our development plans as of December 31, 2014, we have committed to make potential future milestone payments to third parties of up to approximately $2.8 billion as part of our various collaborations, including licensing and development programs. Payments under these agreements generally become due and payable only upon achievement of certain development, regulatory or commercial milestones. Because the achievement of these milestones had not occurred as of December 31, 2014, such contingencies have not been recorded in our financial statements. Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful achievement of certain development, regulatory approval and commercial milestones. We anticipate that we may pay approximately $142.2 million of milestone payments in 2015, provided various development, regulatory or commercial milestones are achieved. TYSABRI Contingent Payments On April 2, 2013, we acquired full ownership of all remaining rights to TYSABRI from Elan that we did not already own or control. Under the terms of the acquisition agreement, we are obligated to make contingent payments to Elan of 18% on annual worldwide net sales up to $2.0 billion and 25% on annual worldwide net sales that exceed $2.0 billion. Royalty payments to Elan and other third parties are recognized as cost of sales within our consolidated statements of income. Contingent Consideration related to Business Combinations In connection with our purchase of the noncontrolling interests in our joint venture investments in Biogen Dompé SRL and Biogen Dompé Switzerland GmbH and our acquisitions of Stromedix, Biogen Idec International Neuroscience GmbH (BIN) and BIH, we may pay up to approximately $850 million in remaining milestones based upon the achievement of certain events. These milestones may not be achieved. As the acquisitions of the noncontrolling interests in our joint venture investments and our acquisitions of Stromedix and BIN, formerly Panima Pharmaceuticals AG, occurred after January 1, 2009, we record contingent consideration liabilities at their fair value on the acquisition date and revalue these obligations each reporting period. For additional information related to our acquisition of Stromedix please read Note 2, Acquisitions, to our consolidated financial statements included in this report. BIH In connection with our acquisition of BIH, formerly Syntonix, in January 2007, we agreed to pay up to an additional $80.0 million if certain milestone events associated with the development of BIH’s lead product, ALPROLIX are achieved. The first $40.0 million contingent payment was achieved in the first quarter of 2010. We paid an additional $20.0 million during the second quarter of 2014 as ALPROLIX was approved for the treatment of hemophilia B. A second $20.0 million contingent payment will occur if prior to the tenth anniversary of the closing date, a marketing authorization is granted by the EMA for ALPROLIX. Fumapharm AG In 2006, we acquired Fumapharm AG. As part of this acquisition we acquired FUMADERM and TECFIDERA (together, Fumapharm Products). We are required to make contingent payments to former shareholders of Fumapharm AG or holders of their rights based on the attainment of certain cumulative sales levels of Fumapharm Products and the level of total net sales of Fumapharm Products in the prior twelve month period, as defined in the acquisition agreement. During 2014, we paid a $25.0 million contingent payment as we reached the $1.0 billion cumulative sales level related to the Fumapharm Products in 2013, a $150.0 million contingent payment as we reached the $2.0 billion cumulative sales level related to Fumapharm Products in the second quarter of 2014, a $200.0 million contingent payment as we reached the $3.0 billion cumulative sales level in the third quarter of 2014 and accrued $250.0 million upon reaching $4.0 billion in total cumulative sales of Fumapharm Products, in the fourth quarter of 2014. We will owe an additional $300.0 million contingent payment for every additional $1.0 billion in cumulative sales level of Fumapharm Products reached if the prior 12 months sales of the Fumapharm Products exceed $3.0 billion, until such time as the cumulative sales level reaches $20.0 billion, at which time no further contingent payments shall be due. These payments will be accounted for as an increase to goodwill as incurred, in accordance with the accounting standard applicable to business combinations when we acquired Fumapharm. Any portion of the payment which is tax deductible will be recorded as a reduction to goodwill. Payments are due within 60 days following the end of the quarter in which the applicable cumulative sales level has been reached. 58 Other Off-Balance Sheet Arrangements We do not have any relationships with entities often referred to as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements. As such, we are not exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships. We consolidate variable interest entities if we are the primary beneficiary. Legal Matters For a discussion of legal matters as of December 31, 2014, please read Note 21, Litigation to our consolidated financial statements included in this report. Critical Accounting Estimates The preparation of our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP), requires us to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We evaluate our estimates, judgments and assumptions on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. Revenue Recognition and Related Allowances We recognize revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; our price to the customer is fixed or determinable; and collectability is reasonably assured. Product Revenues Revenues from product sales are recognized when title and risk of loss have passed to the customer, which is typically upon delivery. The timing of distributor orders and shipments can cause variability in earnings. Reserves for Discounts and Allowances We establish reserves for trade term discounts, wholesaler incentives, Medicaid and managed care rebates, VA and PHS discounts, product returns and other governmental discounts or applicable allowances associated with the implementation of pricing actions in certain of international markets in which we operate. These reserves are based on estimates of the amounts earned or to be claimed on the related sales. Our estimates take into consideration our historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying patterns. If actual results vary, we may need to adjust these estimates, which could have an effect on earnings in the period of the adjustment. In addition to the discounts and rebates described above and classified as a reduction of revenue, we also maintain certain customer service contracts with distributors and other customers in the distribution channel that provide us with inventory management, data and distribution services. To the extent we can demonstrate a separable benefit and fair value for these services, we classify these payments within selling, general and administrative expenses. Revenues from Unconsolidated Joint Business Revenues from unconsolidated joint business consists of (i) our share of pre-tax profits and losses in the U.S. for RITUXAN and GAZYVA; (ii) reimbursement of our selling and development expenses in the U.S. for RITUXAN; and (iii) revenue on sales in the rest of world for RITUXAN, which consist of our share of pre-tax co-promotion profits in Canada and royalty revenue on sales outside the U.S. and Canada by F. Hoffmann-La Roche Ltd. (Roche) and its sublicensees. Pre-tax co-promotion profits on RITUXAN are calculated and paid to us by Genentech in the U.S. and by Roche in Canada. Pre-tax co- promotion profits consist of U.S. and Canadian net sales to third-party customers less the cost to manufacture, third-party royalty expenses, distribution, selling, and marketing expenses, and joint development expenses incurred by Genentech, Roche and us. We record our share of the pretax co-promotion profits on RITUXAN in Canada and royalty revenues on sales outside the U.S. on a cash basis as we do not have the ability to estimate these profits or royalty revenue in the period incurred. Additionally, our share of the pre-tax profits on RITUXAN and GAZYVA in the U.S. includes estimates made by Genentech and those estimates are subject to change. Actual results may ultimately differ from our estimates. 59 Concentrations of Credit Risk The majority of our receivables arise from product sales in the United States and Europe and are primarily due from wholesale distributors, public hospitals and other government entities. We monitor the financial performance and creditworthiness of our large customers so that we can properly assess and respond to changes in their credit profile. We continue to monitor these conditions, including the volatility associated with international economies and the relevant financial markets, and assess their possible impact on our business. The credit and economic conditions within many of the international markets in which we operate, particularly in certain countries throughout Europe, such as Italy, Spain and Portugal, remain uncertain. These conditions have resulted in, and may continue to result in, an increase in the average length of time that it takes to collect on our accounts receivable outstanding in these countries. In Portugal and select regions in Spain where our collections have slowed and a significant portion of these receivables are routinely being collected beyond our contractual payment terms and over periods in excess of one year, we have discounted our receivables and reduced related revenues based on the period of time that we estimate those amounts will be paid, to the extent such period exceeds one year, using the country’s market-based borrowing rate for such period. The related receivables are classified at the time of sale as non-current assets. To date, we have not experienced any significant losses with respect to the collection of our accounts receivable. If economic conditions worsen and/or the financial condition of our customers were to further deteriorate, our risk of collectability may increase, which may result in additional allowances and/or significant bad debts. For additional information related to our concentration of credit risk associated with our accounts receivable balances, please read the subsection above entitled “Credit Risk” in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Capitalization of Inventory Costs We capitalize inventory costs associated with our products prior to regulatory approval, when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized. We consider numerous attributes in evaluating whether the costs to manufacture a particular product should be capitalized as an asset. We assess the regulatory approval process and where the particular product stands in relation to that approval process, including any known safety or efficacy concerns, potential labeling restrictions and other impediments to approval. We evaluate our anticipated research and development initiatives and constraints relating to the product and the indication in which it will be used. We consider our manufacturing environment including our supply chain in determining logistical constraints that could hamper approval or commercialization. We consider the shelf life of the product in relation to the expected timeline for approval and we consider patent related or contract issues that may prevent or delay commercialization. We also base our judgment on the viability of commercialization, trends in the marketplace and market acceptance criteria. Finally, we consider the reimbursement strategies that may prevail with respect to the product and assess the economic benefit that we are likely to realize. We expense previously capitalized costs related to pre-approval inventory upon a change in such judgment, due to, among other potential factors, a denial or significant delay of approval by necessary regulatory bodies. Acquired Intangible Assets, including In-process Research and Development (IPR&D) Effective January 1, 2009, when we purchase a business, the acquired IPR&D is measured at fair value, capitalized as an intangible asset and tested for impairment at least annually until commercialization, after which time the IPR&D is amortized over its estimated useful life. If we acquire an asset or group of assets that do not meet the definition of a business under applicable accounting standards, the acquired IPR&D is expensed on its acquisition date. Future costs to develop these assets are recorded to research and development expense as they are incurred. We have acquired, and expect to continue to acquire, intangible assets through the acquisition of biotechnology companies or through the consolidation of variable interest entities. These intangible assets primarily consist of technology associated with human therapeutic products and in-process research and development product candidates. When significant identifiable intangible assets are acquired, we generally engage an independent third-party valuation firm to assist in determining the fair values of these assets as of the acquisition date. Management will determine the fair value of less significant identifiable intangible assets acquired. Discounted cash flow models are typically used in these valuations, and these models require the use of significant estimates and assumptions including but not limited to: • • • estimating the timing of and expected costs to complete the in-process projects; projecting regulatory approvals; estimating future cash flows from product sales resulting from completed products and in process projects; and 60 • developing appropriate discount rates and probability rates by project. We believe the fair values assigned to the intangible assets acquired are based upon reasonable estimates and assumptions given available facts and circumstances as of the acquisition dates. If these projects are not successfully developed, the sales and profitability of the company may be adversely affected in future periods. Additionally, the value of the acquired intangible assets may become impaired. We believe that the foregoing assumptions used in the IPR&D analysis were reasonable at the time of the respective acquisition. No assurance can be given, however, that the underlying assumptions used to estimate expected project sales, development costs or profitability, or the events associated with such projects, will transpire as estimated. Impairment and Amortization of Long-lived Assets and Accounting for Goodwill Long-lived Assets Other than Goodwill Long-lived assets to be held and used, include property, plant and equipment as well as intangible assets, including IPR&D and trademarks. Property, plant and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. We review our intangible assets with indefinite lives for impairment annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. When performing our impairment assessment, we calculate the fair value using the same methodology as described above under "Acquired Intangible Assets, including In-process Research and Development (IPR&D)". If the carrying value of our intangible assets with indefinite lives exceeds its fair value, then the intangible asset is written-down to its fair values. Our most significant intangible assets are our acquired and in-licensed rights and patents and developed technology. Acquired and in-licensed rights and patents primarily relates to our acquisition of all remaining rights to TYSABRI from Elan. Developed technology primarily relates to our AVONEX product, which was recorded in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation in 2003. We amortize the intangible assets related to TYSABRI and AVONEX using the economic consumption method based on revenue generated from the products underlying the related intangible assets. An analysis of the anticipated lifetime revenues of TYSABRI and AVONEX is performed annually during our long range planning cycle, which is generally updated in the third quarter of each year, and whenever events or changes in circumstances would significantly affect the anticipated lifetime revenues of TYSABRI or AVONEX. For additional information on the impairment charges related to our long-lived assets during 2014, please read Note 7, Intangible Assets and Goodwill to our consolidated financial statements included within this report. Impairment charges related to our long-lived assets during 2013 and 2012 were immaterial. Goodwill Goodwill relates largely to amounts that arose in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation. Our goodwill balances represent the difference between the purchase price and the fair value of the identifiable tangible and intangible net assets when accounted for using the purchase method of accounting. We assess our goodwill balance within our single reporting unit annually, as of October 31, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable to determine whether any impairment in this asset may exist and, if so, the extent of such impairment. We compare the fair value of our reporting unit to its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of our reporting unit, then we would need to determine the implied fair value of our reporting unit’s goodwill. If the carrying value of our reporting unit’s goodwill exceeds its implied fair value, then we would record an impairment loss equal to the difference. We completed our required annual impairment test in the fourth quarter of 2014, 2013 and 2012 and determined in each of those periods that the carrying value of goodwill was not impaired. In each year, the fair value of our reporting unit, which includes goodwill, was significantly in excess of the carrying value of our reporting unit. 61 Investments, including Fair Value Measures and Impairments We invest in various types of securities, including short-term and long-term marketable securities, principally corporate notes, government securities including government sponsored enterprise mortgage-backed securities and credit card and auto loan asset-backed securities, in which our excess cash balances are invested. In accordance with the accounting standard for fair value measurements, we have classified our financial assets as Level 1, 2 or 3 within the fair value hierarchy. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets that we have the ability to access. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset. As noted in Note 8, Fair Value Measurements to our consolidated financial statements, a majority of our financial assets have been classified as Level 2. These assets have been initially valued at the transaction price and subsequently valued utilizing third party pricing services. The pricing services use many observable market inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. We validate the prices provided by our third party pricing services by understanding the models used, obtaining market values from other pricing sources and analyzing pricing data in certain instances. We also have some investments classified as Level 3 whose fair value is initially measured at transaction prices and subsequently valued using the pricing of recent financing or by reviewing the underlying economic fundamentals and liquidation value of the companies. We apply judgments and estimates when we validate the prices provided by third parties. While we believe the valuation methodologies are appropriate, the use of valuation methodologies is highly judgmental and changes in methodologies can have a material impact on our results of operations. Impairment We conduct periodic reviews to identify and evaluate each investment that has an unrealized loss, in accordance with the meaning of other-than-temporary impairment and its application to certain investments. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. Unrealized losses on available-for-sale debt securities that are determined to be temporary, and not related to credit loss, are recorded, net of tax, in accumulated other comprehensive income. For available-for-sale debt securities with unrealized losses, management performs an analysis to assess whether we intend to sell or whether we would more likely than not be required to sell the security before the expected recovery of the amortized cost basis. Where we intend to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is reflected within earnings as an impairment loss. Regardless of our intent to sell a security, we perform additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where we do not expect to receive cash flows sufficient to recover the amortized cost basis of a security and are reflected within earnings as an impairment loss. Share-Based Compensation We make certain assumptions in order to value and record expense associated with awards made under our share-based compensation arrangements. Changes in these assumptions may lead to variability with respect to the amount of expense we recognize in connection with share-based payments. Determining the appropriate valuation model and related assumptions requires judgment, and includes estimating the expected market price of our stock on vesting date and stock price volatility as well as the term of the expected awards. Determining the appropriate amount to expense based on the anticipated achievement of performance targets requires judgment, including forecasting the achievement of future financial targets. The estimate of expense is revised periodically based on the probability of achieving the required performance targets and adjustments are made throughout the performance as appropriate. The cumulative impact of any revision is reflected in the period of change. We also estimate forfeitures over the requisite service period when recognizing share-based compensation expense based on historical rates and forward-looking factors; these estimates are adjusted to the extent that actual forfeitures differ, or are expected to materially differ, from our estimates. 62 Contingent Consideration For acquisitions completed before January 1, 2009, we record contingent consideration resulting from a business combination when the contingency is resolved. For acquisitions completed after January 1, 2009, we record contingent consideration resulting from a business combination at its fair value on the acquisition date. Each reporting period thereafter, we revalue these obligations and record increases or decreases in their fair value as an adjustment to contingent consideration expense within the consolidated statement of income. Changes in the fair value of the contingent consideration obligations can result from adjustments to the discount rates and achievement and timing of any cumulative sales-based and development milestones, or changes in the probability of certain clinical events and changes in the assumed probability associated with regulatory approval. These fair value measurements represent Level 3 measurements as they are based on significant inputs not observable in the market. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, changes in assumptions described above, could have a material impact on the amount of contingent consideration expense we record in any given period. Income Taxes We prepare and file income tax returns based on our interpretation of each jurisdiction’s tax laws and regulations. In preparing our consolidated financial statements, we estimate our income tax liability in each of the jurisdictions in which we operate by estimating our actual current tax expense together with assessing temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. Significant management judgment is required in assessing the realizability of our deferred tax assets. In performing this assessment, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, under the applicable financial accounting standards, we are allowed to consider the scheduled reversal of deferred tax liabilities, projected future taxable income, and the effects of tax planning strategies. Our estimates of future taxable income include, among other items, our estimates of future income tax deductions related to the exercise of stock options. In the event that actual results differ from our estimates, we adjust our estimates in future periods and we may need to establish a valuation allowance, which could materially impact our financial position and results of operations. All tax effects associated with intercompany transfers of assets within our consolidated group, both current and deferred, are recorded as a prepaid tax or deferred charge and recognized through the consolidated statement of income when the asset transferred is sold to a third party or otherwise recovered through amortization of the asset's remaining economic life. If the asset transferred becomes impaired, for example through the discontinuation of a research program, we will expense any remaining deferred charge or prepaid tax. We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis and consider various factors, that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in process audit activities and changes in facts or circumstances related to a tax position. We adjust the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Our liabilities for uncertain tax positions can be relieved only if the contingency becomes legally extinguished through either payment to the taxing authority or the expiration of the statute of limitations, the recognition of the benefits associated with the position meet the “more-likely-than-not” threshold or the liability becomes effectively settled through the examination process. We consider matters to be effectively settled once the taxing authority has completed all of its required or expected examination procedures, including all appeals and administrative reviews; we have no plans to appeal or litigate any aspect of the tax position; and we believe that it is highly unlikely that the taxing authority would examine or re- examine the related tax position. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense. We earn a significant amount of our operating income outside the U.S. As a result, a portion of our cash, cash equivalents, and marketable securities are held by foreign subsidiaries. We currently do not intend or foresee a need to repatriate these funds. We expect existing domestic cash, cash equivalents, marketable securities and cash flows from operations to continue to be sufficient to fund our domestic operating activities and cash commitments for investing and financing activities for the foreseeable future. 63 As of December 31, 2014, our non-U.S. subsidiaries’ undistributed foreign earnings included in consolidated retained earnings and other basis differences aggregated approximately $4.6 billion. All undistributed foreign earnings of non- U.S. subsidiaries, exclusive of earnings that would result in little or no net income tax expense or which were previously taxed under current U.S. tax law, are reinvested indefinitely in operations outside the U.S. This determination is made on a jurisdiction-by-jurisdiction basis and takes into the account the liquidity requirements in both the U.S. and within our foreign subsidiaries. If we decide to repatriate funds in the future to execute our growth initiatives or to fund any other liquidity needs, the resulting tax consequences would negatively impact our results of operations through a higher effective tax rate and dilution of our earnings. The residual U.S. tax liability, if cumulative amounts were repatriated, would be between $1.5 billion to $1.6 billion as of December 31, 2014.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk The information required by this Item is incorporated by reference to the discussion under “Market Risk” in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Item 8. Financial Statements and Supplementary Data The information required by this Item 8 is contained on pages F-1 through F-65 of this report and is incorporated herein by reference. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures Disclosure Controls and Procedures and Internal Control over Financial Reporting Controls and Procedures We have carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), as of December 31, 2014. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that (a) the information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and (b) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Changes in Internal Control over Financial Reporting There were no changes in our internal control over financial reporting during the quarter ended December 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management’s Annual Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act as a process designed by, or under the supervision of, a company’s principal executive and principal financial officers and effected by a company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Our internal control over financial reporting includes those policies and procedures that: 64 • • • pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of our assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2014. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its 2013 Internal Control — Integrated Framework. Based on our assessment, our management has concluded that, as of December 31, 2014, our internal control over financial reporting is effective based on those criteria. The effectiveness of our internal control over financial reporting as of December 31, 2014 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their attestation report, which is included herein.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Summary of Significant Accounting Policies Business Overview Biogen Idec is a global biopharmaceutical company focused on discovering, developing, manufacturing and delivering therapies for neurological, autoimmune and hematologic disorders. Our principal marketed products include AVONEX, PLEGRIDY, TECFIDERA, TYSABRI, and FAMPYRA for multiple sclerosis (MS), ALPROLIX for hemophilia B and ELOCTATE for hemophilia A. We also collaborate on the development and commercialization of RITUXAN for the treatment of non-Hodgkin's lymphoma, chronic lymphocytic leukemia and other conditions and share profits and losses for GAZYVA which is approved for the treatment of chronic lymphocytic leukemia. Consolidation Our consolidated financial statements reflect our financial statements, those of our wholly-owned subsidiaries and those of certain variable interest entities where we are the primary beneficiary. For consolidated entities where we own or are exposed to less than 100% of the economics, we record net income (loss) attributable to noncontrolling interests in our consolidated statements of income equal to the percentage of the economic or ownership interest retained in such entities by the respective noncontrolling parties. Intercompany balances and transactions are eliminated in consolidation. In determining whether we are the primary beneficiary of an entity and therefore required to consolidate, we apply a qualitative approach that determines whether we have both (1) the power to direct the economically significant activities of the entity and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity. These considerations impact the way we account for our existing collaborative relationships and other arrangements. We continuously assess whether we are the primary beneficiary of a variable interest entity as changes to existing relationships or future transactions may result in us consolidating or deconsolidating one or more of our collaborators or partners. Use of Estimates The preparation of our consolidated financial statements requires us to make estimates, judgments, and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and judgments and methodologies. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Revenue Recognition We recognize revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; our price to the customer is fixed or determinable; and collectability is reasonably assured. Product Revenues Revenues from product sales are recognized when title and risk of loss have passed to the customer, which is typically upon delivery. Product revenues are recorded net of applicable reserves for discounts and allowances. Reserves for Discounts and Allowances We establish reserves for trade term discounts, wholesaler incentives, Medicaid rebates, Veterans Administration (VA) and Public Health Service (PHS) discounts, managed care rebates, product returns and other governmental rebates or applicable allowances, including those associated with the implementation of pricing actions in certain of the international markets in which we operate. Reserves established for these discounts and allowances are classified as reductions of accounts receivable (if the amount is payable to our customer) or a liability (if the amount is payable to a party other than our customer). These reserves are based on estimates of the amounts earned or to be claimed on the related sales. Our estimates take into consideration our historical experience, current contractual and statutory requirements, specific known market events and trends, industry date and forecasted customer buying and payment patterns. Actual amounts may ultimately differ from our estimates. If actual results vary, we adjust these estimates, which could have an effect on earnings in the period of adjustment. Product revenue reserves are categorized as follows: discounts, contractual adjustments and returns. F- 9 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Discounts include trade term discounts and wholesaler incentives. Trade term discounts and wholesaler incentives primarily relate to estimated obligations for credits to be granted to wholesalers for remitting payment on their purchases within established incentive periods and credits to be granted to wholesalers for compliance with various contractually-defined inventory management practices, respectively. We determine these reserves based on our historical experience, including the timing of customer payments. Contractual adjustments primarily relate to Medicaid and managed care rebates, VA and PHS discounts, specialty pharmacy program fees and other governmental rebates or applicable allowances. • Medicaid rebates relate to our estimated obligations to states under established reimbursement arrangements. Rebate accruals are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a liability which is included in other current liabilities. Our liability for Medicaid rebates consists of estimates for claims that a state will make for the current quarter, claims for prior quarters that have been estimated for which an invoice has not been received, invoices received for claims from the prior quarters that have not been paid, and an estimate of potential claims that will be made for inventory that exists in the distribution channel at period end. • Governmental rebates or chargebacks, including VA and PHS discounts, represent our estimated obligations resulting from contractual commitments to sell products to qualified healthcare providers at prices lower than the list prices we charge to wholesalers which provide those products. The wholesaler charges us for the difference between what the wholesaler pays for the products and the ultimate selling price to the qualified healthcare providers. Rebate and chargeback reserves are established in the same period as the related revenue is recognized, resulting in a reduction in product revenue and accounts receivable. Chargeback amounts are generally determined at the time of resale to the qualified healthcare provider from the wholesaler, and we generally issue credits for such amounts within a few weeks of the wholesaler notifying us about the resale. Our reserves for VA, PHS and chargebacks consists of amounts that we expect to issue for inventory that exists at the wholesalers that we expect will be sold to qualified healthcare providers and chargebacks that wholesalers have claimed for which we have not issued a credit. • Managed care rebates represent our estimated obligations to third parties, primarily pharmacy benefit managers. Rebate accruals are recorded in the same period the related revenue is recognized, resulting in a reduction of product revenue and the establishment of a liability which is included in accrued expenses and other current liabilities. These rebates result from performance-based goals that are primarily based on attaining contractually specified sales volumes and growth and price increase limit allowances (price protection). The calculation of the accrual for these rebates is based on an estimate of the customer’s buying patterns and the resulting applicable contractual rebate rate(s) to be earned over a contractual period. • Other governmental rebates or applicable allowances primarily relate to mandatory rebates and discounts in markets where government-sponsored healthcare systems are the primary payors for healthcare. Product returns are established for returns expected to be made by wholesalers and are recorded in the period the related revenue is recognized, resulting in a reduction to product sales. In accordance with contractual terms, wholesalers are permitted to return product for reasons such as damaged or expired product. The majority of wholesaler returns are due to product expiration. Expired product return reserves are estimated through a comparison of historical return data to their related sales on a production lot basis. Historical rates of return are determined for each product and are adjusted for known or expected changes in the marketplace specific to each product. In addition to the discounts, rebates and product returns described above and classified as a reduction of revenue, we also maintain certain customer service contracts with distributors and other customers in the distribution channel that provide us with inventory management, data and distribution services. To the extent we can demonstrate a separable benefit and fair value for these services, we classify these payments within selling, general and administrative expenses. We also distribute no-charge product to qualifying patients under our patient assistance and patient replacement goods program. This program is administered through our distribution partners, which ship product for qualifying patients from their own inventory received from us. Gross revenue and the related reserves are not recorded on product shipped under this program and cost of sales is recorded when the product is shipped. F- 10 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Revenues from Unconsolidated Joint Business Revenues from unconsolidated joint business consists of (i) our share of pre-tax profits and losses in the U.S. for RITUXAN and GAZYVA; (ii) reimbursement of our selling and development expenses in the U.S. for RITUXAN; and (iii) revenue on sales in the rest of world for RITUXAN, which consist of our share of pre-tax co-promotion profits in Canada and royalty revenue on sales outside the U.S. and Canada by F. Hoffmann-La Roche Ltd. (Roche) and its sublicensees. Pre-tax co-promotion profits on RITUXAN are calculated and paid to us by Genentech in the U.S. and by Roche in Canada. Pre-tax co- promotion profits consist of U.S. and Canadian net sales to third-party customers less the cost to manufacture, third-party royalty expenses, distribution, selling, and marketing expenses, and joint development expenses incurred by Genentech, Roche and us. We record our share of the pretax co-promotion profits on RITUXAN in Canada and royalty revenues on sales outside the U.S. on a cash basis as we do not have the ability to estimate these profits or royalty revenue in the period incurred. Additionally, our share of the pre-tax profits on RITUXAN and GAZYVA in the U.S. includes estimates made by Genentech and those estimates are subject to change. Actual results may ultimately differ from our estimates. For additional information related to our collaboration with Genentech, please read Note 20, Collaborative and Other Relationships, to these consolidated financial statements. Royalty Revenues We receive royalty revenues on sales by our licensees of other products covered under patents that we own. We do not have future performance obligations under these license arrangements. We record these revenues based on estimates of the sales that occurred during the relevant period. The relevant period estimates of sales are based on interim data provided by licensees and analysis of historical royalties that have been paid to us, adjusted for any changes in facts and circumstances, as appropriate. Differences between actual and estimated royalty revenues are adjusted for in the period in which they become known, typically the following quarter. Historically, adjustments have not been material when compared to actual amounts paid by licensees. If we are unable to reasonably estimate royalty revenue or do not have access to the information, then we record royalty revenues on a cash basis. Multiple-Element Revenue Arrangements We may enter into transactions that involve the sale of products and related services under multiple element arrangements. In accounting for these transactions, we assess the elements of the contract and whether each element has standalone value and allocate revenue to the various elements based on their estimated selling price. The selling price of a revenue generating element can be based on current selling prices offered by us or another party for current products or management’s best estimate of a selling price. Revenue allocated to an individual element is recognized when all other revenue recognition criteria are met for that element. Fair Value Measurements We have certain financial assets and liabilities recorded at fair value which have been classified as Level 1, 2 or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements. • • • Level 1 — Fair values are determined utilizing quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access; Level 2 — Fair values are determined by utilizing quoted prices for identical or similar assets and liabilities in active markets or other market observable inputs such as interest rates, yield curves and foreign currency spot rates; and Level 3 — Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. The majority of our financial assets have been classified as Level 2. Our financial assets (which include our cash equivalents, derivative contracts, marketable debt securities, and plan assets for deferred compensation) have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. We validate the prices provided by our third party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources and analyzing pricing data in certain instances. After completing our validation procedures, we did not adjust or override any fair value measurements provided by our pricing services as of December 31, 2014 and 2013, respectively. F- 11 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) We also maintain venture capital investments classified as Level 3 whose fair value is initially measured at transaction prices and subsequently valued using the pricing of recent financing or by reviewing the underlying economic fundamentals and liquidation value of the companies. These investments include investments in certain venture capital funds which primarily invest in small privately-owned, venture-backed biotechnology companies. The fair value of our investments in these venture capital funds has been estimated using the net asset value of the fund. Gains and losses (realized and unrealized) included in earnings for the period are reported in other income (expense), net. The investments cannot be redeemed within the funds. Distributions from each fund will be received as the underlying investments of the fund are liquidated. We apply judgments and estimates when we validate the prices provided by third parties. While we believe the valuation methodologies are appropriate, the use of valuation methodologies is highly judgmental and changes in methodologies can have a material impact on our results of operations. Other The carrying amounts reflected in the consolidated balance sheets for cash equivalents, current accounts receivable, due from unconsolidated joint business, other current assets, accounts payable, and accrued expenses and other, approximate fair value due to their short-term maturities. Cash and Cash Equivalents We consider only those investments which are highly liquid, readily convertible to cash and that mature within three months from date of purchase to be cash equivalents. As of December 31, 2014 and 2013, cash equivalents were comprised of money market funds and commercial paper, overnight reverse repurchase agreements, and other debt securities with maturities less than 90 days from the date of purchase. Accounts Receivable The majority of our accounts receivable arise from product sales and primarily represent amounts due from our wholesale distributors, public hospitals and other government entities. We monitor the financial performance and creditworthiness of our large customers so that we can properly assess and respond to changes in their credit profile. We provide reserves against trade receivables for estimated losses that may result from a customer’s inability to pay. Amounts determined to be uncollectible are charged or written-off against the reserve. In countries where we have experienced a pattern of payments extending beyond our contractual payment term and we expect to collect receivables greater than one year from the time of sale, we have discounted our receivables and reduced related revenues over the period of time that we estimate those amounts will be paid using the country’s market-based borrowing rate for such period. The related receivables are classified at the time of sale as non-current assets. We accrete interest income on these receivables, which is recognized as a component of other income (expense), net within our consolidated statement of income. Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk include cash and cash equivalents, investments, derivatives, and accounts receivable. We attempt to minimize the risks related to cash and cash equivalents and investments by investing in a broad and diverse range of financial instruments as previously defined by us. We have established guidelines related to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. Our investment portfolio is maintained in accordance with our investment policy, which defines allowable investments, specifies credit quality standards and limits the credit exposure of any single issuer. We minimize credit risk resulting from derivative instruments by choosing only highly rated financial institutions as counterparties. Concentrations of credit risk with respect to receivables, which are typically unsecured, are limited due to the wide variety of customers and markets using our products, as well as their dispersion across many different geographic areas. The majority of our accounts receivable arise from product sales in the United States and Europe and have standard payment terms which generally require payment within 30 to 90 days. We monitor the financial performance and creditworthiness of our large customers so that we can properly assess and respond to changes in their credit profile. We continue to monitor these conditions and assess their possible impact on our business. For additional information related to this concentration of credit risk, please read Note 4, Accounts Receivable to these consolidated financial statements. As of December 31, 2014 and 2013, two wholesale distributors individually accounted for approximately 34.4% and 23.3%, and 34.5% and 15.7%, of consolidated trade receivables, respectively. F- 12 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Marketable Securities and Other Investments Marketable Debt Securities Available-for-sale debt securities are recorded at fair market value and unrealized gains and losses are included in accumulated other comprehensive income (loss) in equity, net of related tax effects, unless the security has experienced a credit loss, we have determined that we have the intent to sell the security or we have determined that it is more likely than not that we will have to sell the security before its expected recovery. Realized gains and losses are reported in other income (expense), net, on a specific identification basis. Marketable Equity Securities Our marketable equity securities represent investments in publicly traded equity securities and are included in investments and other assets within our consolidated balance sheet. When assessing whether a decline in the fair value of a marketable equity security is other-than-temporary, we consider the fair market value of the security, the duration of the security’s decline, and prospects for the underlying business, including favorable or adverse clinical trial results, new product initiatives and new collaborative agreements with the companies in which we have invested. Non-Marketable Equity Securities We also invest in equity securities of companies whose securities are not publicly traded and where fair value is not readily available. These investments are recorded using either the cost method or the equity method of accounting, depending on our ownership percentage and other factors that suggest we have significant influence. We monitor these investments to evaluate whether any decline in their value has occurred that would be other-than-temporary, based on the implied value of recent company financings, public market prices of comparable companies, and general market conditions and are included in investments and other assets within our consolidated balance sheet. Evaluating Investments for Other-than-Temporary Impairments We conduct periodic reviews to identify and evaluate each investment that has an unrealized loss, in accordance with the meaning of other-than-temporary impairment and its application to certain investments. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. Unrealized losses on available-for-sale securities that are determined to be temporary, and not related to credit loss, are recorded, net of tax, in accumulated other comprehensive income. For available-for-sale debt securities with unrealized losses, management performs an analysis to assess whether we intend to sell or whether we would more likely than not be required to sell the security before the expected recovery of the amortized cost basis. Where we intend to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is reflected within earnings as an impairment loss. Regardless of our intent to sell a security, we perform additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where we do not expect to receive cash flows sufficient to recover the amortized cost basis of a security. For equity securities, when assessing whether a decline in value is other-than-temporary, we consider the fair market value of the security, the duration of the security’s decline, and the financial condition of the issuer. We then consider our intent and ability to hold the equity security for a period of time sufficient to recover our carrying value. Where we have determined that we lack the intent and ability to hold an equity security to its expected recovery, the security’s decline in fair value is deemed to be other-than-temporary and is reflected within earnings as an impairment loss. Equity Method of Accounting In circumstances where we have the ability to exercise significant influence over the operating and financial policies of a company in which we have an investment, we utilize the equity method of accounting for recording investment activity. In assessing whether we exercise significant influence, we consider the nature and magnitude of our investment, the voting and protective rights we hold, any participation in the governance of the other company, and other relevant factors such as the presence of a collaboration or other business relationship. Under the equity method of accounting, we record within our results of operations our share of income or loss of the other company. F- 13 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Inventory Inventories are stated at the lower of cost or market with cost determined in a manner that approximates the first-in, first- out (FIFO) method. Inventory that can be used in either the production of clinical or commercial products is expensed as research and development costs when selected for use in a clinical manufacturing campaign. Capitalization of Inventory Costs We capitalize inventory costs associated with our products prior to regulatory approval, when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized. We consider numerous attributes in evaluating whether the costs to manufacture a particular product should be capitalized as an asset. We assess the regulatory approval process and where the particular product stands in relation to that approval process, including any known safety or efficacy concerns, potential labeling restrictions and other impediments to approval. We evaluate our anticipated research and development initiatives and constraints relating to the product and the indication in which it will be used. We consider our manufacturing environment including our supply chain in determining logistical constraints that could hamper approval or commercialization. We consider the shelf life of the product in relation to the expected timeline for approval and we consider patent related or contract issues that may prevent or delay commercialization. We also base our judgment on the viability of commercialization, trends in the marketplace and market acceptance criteria. Finally, we consider the reimbursement strategies that may prevail with respect to the product and assess the economic benefit that we are likely to realize. We expense previously capitalized costs related to pre-approval inventory upon a change in such judgment, due to, among other potential factors, a denial or significant delay of approval by necessary regulatory bodies. Obsolescence and Unmarketable Inventory We periodically review our inventories for excess or obsolescence and write-down obsolete or otherwise unmarketable inventory to its estimated net realizable value. If the actual net realizable value is less than that estimated by us, or if it is determined that inventory utilization will further diminish based on estimates of demand, additional inventory write-downs may be required. Additionally, our products are subject to strict quality control and monitoring which we perform throughout the manufacturing process. In the event that certain batches or units of product no longer meet quality specifications, we will record a charge to cost of sales to write-down any unmarketable inventory to its estimated net realizable value. In all cases, product inventory is carried at the lower of cost or its estimated net realizable value. Amounts written-down due to unmarketable inventory are charged to cost of sales. Property, Plant and Equipment Property, plant and equipment are carried at cost, subject to review for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The cost of normal, recurring, or periodic repairs and maintenance activities related to property, plant and equipment are expensed as incurred. The cost for planned major maintenance activities, including the related acquisition or construction of assets, is capitalized if the repair will result in future economic benefits. Interest costs incurred during the construction of major capital projects are capitalized until the underlying asset is ready for its intended use, at which point the interest costs are amortized as depreciation expense over the life of the underlying asset. We also capitalize certain direct and incremental costs associated with the validation effort required for licensing by regulatory agencies of new manufacturing equipment for the production of a commercially approved drug. These costs primarily include direct labor and material and are incurred in preparing the equipment for its intended use. The validation costs are either amortized over the life of the related equipment or expensed as cost of sales when the product produced in the validation process is sold. In addition, we capitalize certain internal use computer software development costs. If the software is an integral part of production assets, these costs are included in machinery and equipment and are amortized on a straight-line basis over the estimated useful lives of the related software, which generally range from three to five years. F- 14 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) We generally depreciate or amortize the cost of our property, plant and equipment using the straight-line method over the estimated useful lives of the respective assets, which are summarized as follows: Asset Category Land Buildings Leasehold Improvements Furniture and Fixtures Machinery and Equipment Computer Software and Hardware Useful Lives Not depreciated 15 to 40 years Lesser of the useful life or the term of the respective lease 5 to 7 years 5 to 20 years 3 to 5 years When we dispose of property, plant and equipment, we remove the associated cost and accumulated depreciation from the related accounts on our consolidated balance sheet and include any resulting gain or loss in our consolidated statement of income. Intangible Assets Our intangible assets consist of acquired and in-licensed rights and patents, developed technology, out-licensed patents, in-process research and development acquired after January 1, 2009, trademarks and trade names. Our intangible assets are recorded at fair value at the time of their acquisition and are stated within our consolidated balance sheets net of accumulated amortization and impairments, if applicable. Intangible assets related to acquired and in-licensed rights and patents, developed technology and out-licensed patents are amortized over their estimated useful lives using the economic consumption method if anticipated future revenues can be reasonably estimated. The straight-line method is used when revenues cannot be reasonably estimated. Amortization is recorded as amortization of acquired intangible assets within our consolidated statements of income. Acquired and in-licensed rights and patents primarily relate to our acquisition of all remaining rights to TYSABRI from Elan Pharma International, Ltd (Elan), an affiliate of Elan Corporation, plc. Developed technology primarily relates to our AVONEX product, which was recorded in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation in 2003. We amortize the intangible assets related to TYSABRI and AVONEX using the economic consumption method based on revenue generated from the products underlying the related intangible assets. An analysis of the anticipated lifetime revenues of TYSABRI and AVONEX is performed annually during our long range planning cycle, which is generally updated in the third quarter of each year, and whenever events or changes in circumstances would significantly affect the anticipated lifetime revenues of TYSABRI or AVONEX. Intangible assets related to trademarks, trade names and in-process research and development prior to commercialization are not amortized because they have indefinite lives, however, they are subject to review for impairment. We review our intangible assets with indefinite lives for impairment annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Acquired In-process Research and Development (IPR&D) Acquired IPR&D represents the fair value assigned to research and development assets that have not reached technological feasibility. The value assigned to acquired IPR&D is determined by estimating the costs to develop the acquired technology into commercially viable products, estimating the resulting revenue from the projects, and discounting the net cash flows to present value. The revenue and costs projections used to value acquired IPR&D are, as applicable, reduced based on the probability of success of developing a new drug. Additionally, the projections consider the relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by us and our competitors. The rates utilized to discount the net cash flows to their present value are commensurate with the stage of development of the projects and uncertainties in the economic estimates used in the projections. Upon the acquisition of IPR&D, we complete an assessment of whether our acquisition constitutes the purchase of a single asset or a group of assets. We consider multiple factors in this assessment, including the nature of the technology acquired, the presence or absence of separate cash flows, the development process and stage of completion, quantitative significance and our rationale for entering into the transaction. F- 15 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) If we acquire a business as defined under applicable accounting standards, then the acquired IPR&D is capitalized as an intangible asset. If we acquire an asset or group of assets that do not meet the definition of a business, then the acquired IPR&D is expensed on its acquisition date. Future costs to develop these assets are recorded to research and development expense as they are incurred. We review amounts capitalized as acquired IPR&D for impairment at least annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable. When performing our impairment assessment, we calculate the fair value using the same methodology as described above. If the carrying value of our acquired IPR&D exceeds its fair value, then the intangible asset is written-down to its fair value. Goodwill Goodwill represents the difference between the purchase price and the fair value of the identifiable tangible and intangible net assets when accounted for using the purchase method of accounting. Goodwill is not amortized, but reviewed for impairment. Goodwill is reviewed annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying value of the goodwill might not be recoverable. We compare the fair value of our reporting unit to its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of our reporting unit, then we would need to determine the implied fair value of our reporting unit’s goodwill. If the carrying value of our reporting unit’s goodwill exceeds its implied fair value, then we would record an impairment loss equal to the difference. As described in Note 25, Segment Information to these consolidated financial statements, we operate in one operating segment which we consider our only reporting unit. Impairment of Long-Lived Assets Long-lived assets to be held and used, including property, plant and equipment and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the assets, the assets are written-down to their fair values. Long-lived assets to be disposed of are carried at fair value less costs to sell. Contingent Consideration The consideration for our acquisitions often includes future payments that are contingent upon the occurrence of a particular event. For acquisitions completed before January 1, 2009, we record contingent consideration resulting from a business combination when the contingency is resolved. For acquisitions that qualify as business combinations completed after January 1, 2009, we record an obligation for such contingent payments at fair value on the acquisition date. We estimate the fair value of contingent consideration obligations through valuation models that incorporate probability-adjusted assumptions related to the achievement of the milestones and thus likelihood of making related payments. We revalue these contingent consideration obligations each reporting period. Changes in the fair value of our contingent consideration obligations are recognized within our consolidated statements of income. Changes in the fair value of the contingent consideration obligations can result from changes to one or multiple inputs, including adjustments to the discount rates, changes in the amount or timing of expected expenditures associated with product development, changes in the amount or timing of cash flows and reserves associated with products upon commercialization, changes in the assumed achievement or timing of any cumulative sales-based and development milestones, changes in the probability of certain clinical events and changes in the assumed probability associated with regulatory approval. Discount rates in our valuation models represent a measure of the credit risk associated with settling the liability. The period over which we discount our contingent obligations is based on the current development stage of the product candidates, our specific development plan for that product candidate adjusted for the probability of completing the development step, and when the contingent payments would be triggered. In estimating the probability of success, we utilize data regarding similar milestone events from several sources, including industry studies and our own experience. These fair value measurements are based on significant inputs not observable in the market. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period. Accordingly, changes in assumptions could have a material impact on the amount of contingent consideration expense we record in any given period. F- 16 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Derivative Instruments and Hedging Activities We recognize all derivative instruments as either assets or liabilities at fair value in our consolidated balance sheets. Changes in the fair value of derivatives are recorded each period in current earnings or accumulated other comprehensive income (loss), depending on whether a derivative is designated as part of a hedge transaction and, if so, the type of hedge transaction. We classify the cash flows from these instruments in the same category as the cash flows from the hedged items. We do not hold or issue derivative instruments for trading or speculative purposes. We assess, both at inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of the hedged items. We also assess hedge ineffectiveness on a quarterly basis and record the gain or loss related to the ineffective portion to current earnings. If we determine that a forecasted transaction is no longer probable of occurring, we discontinue hedge accounting for the affected portion of the hedge instrument, and any related unrealized gain or loss on the contract is recognized in current earnings. Translation of Foreign Currencies The functional currency for most of our foreign subsidiaries is their local currency. For our non-U.S. subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange at the balance sheet date. Income and expense items are translated at the average foreign exchange rates for the period. Adjustments resulting from the translation of the financial statements of our foreign operations into U.S. dollars are excluded from the determination of net income and are recorded in accumulated other comprehensive income, a separate component of equity. For subsidiaries where the functional currency differs from the local currency, non-monetary assets and liabilities are translated at the rate of exchange in effect on the date assets were acquired while monetary assets and liabilities are translated at current rates of exchange as of the balance sheet date. Income and expense items are translated at the average foreign currency rates for the period. Translation adjustments of these subsidiaries are included in net income. Royalty Cost of Sales We make royalty payments to a number of third parties under license or purchase agreements associated with our acquisition of intellectual property. These royalty payments are typically calculated as a percentage (royalty rate) of the sales of our products within a particular year. That royalty rate may remain constant, increase or decrease within each year based on the total amount of sales during the annual period. Each quarterly period we estimate our total royalty obligation for the full year and recognize the proportional amount as cost of sales based on actual quarterly sales as a percentage of full year estimated sales. For example, if the level of net sales in any calendar year increases the royalty rate within the year, we will record our cost of sales at an even rate over the year, based on the estimated blended royalty rate. Accounting for Share-Based Compensation Our share-based compensation programs grant awards that have included stock options, restricted stock units which vest based on stock performance known as market stock units (MSUs), performance-vested restricted stock units which settle in cash (CSPUs), time-vested restricted stock units (RSUs), performance-vested restricted stock units which can be settled in cash or shares of our common stock (PUs) at the sole discretion of the Compensation and Management Development Committee of the Board of Directors and shares issued under our employee stock purchase plan (ESPP). We charge the estimated fair value of awards against income over the requisite service period, which is generally the vesting period. Where awards are made with non-substantive vesting periods (for instance, where a portion of the award vests upon retirement eligibility), we estimate and recognize expense based on the period from the grant date to the date on which the employee is retirement eligible. The fair values of our stock option grants are estimated as of the date of grant using a Black-Scholes option valuation model. The estimated fair values of the stock options are then expensed over the options’ vesting periods. The fair values of our MSUs are estimated using a lattice model with a Monte Carlo simulation. We apply an accelerated attribution method to recognize stock based compensation expense over the applicable service period, net of estimated forfeitures, when accounting for our MSUs. The probability of actual shares expected to be earned is considered in the grant date valuation, therefore the expense will not be adjusted to reflect the actual units earned. The fair values of our RSUs are based on the market value of our stock on the date of grant. Compensation expense for RSUs is recognized straight-line over the applicable service period. F- 17 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) We apply an accelerated attribution method to recognize stock based compensation expense when accounting for our CSPUs and PUs and the fair value of the liability is remeasured at the end of each reporting period through expected settlement. Compensation expense associated with CSPUs and PUs are based upon the stock price and the number of units expected to be earned after assessing the probability that certain performance criteria will be met and the associated targeted payout level that is forecasted will be achieved, net of estimated forfeitures. Cumulative adjustments are recorded each quarter to reflect changes in the stock price and estimated outcome of the performance-related conditions until the date results are determined and settled. The purchase price of common stock under our ESPP is equal to 85% of the lower of (i) the market value per share of the common stock on the first business day of an offering period or (ii) the market value per share of the common stock on the purchase date. The fair value of the discounted purchases made under our ESPP is calculated using the Black-Scholes model. The fair value of the look-back provision plus the 15% discount is recognized as compensation expense over the 90 day purchase period. Research and Development Expenses Research and development expenses consist of upfront fees and milestones paid to collaborators and expenses incurred in performing research and development activities, which include compensation and benefits, facilities expenses, overhead expenses, clinical trial and related clinical manufacturing expenses, write-offs of pre-approved inventory that was previously capitalized that are determined to be no longer realizable, fees paid to contract research organizations (CROs) and other outside expenses. Research and development expenses are expensed as incurred. Payments we make for research and development services prior to the services being rendered are recorded as prepaid assets on our consolidated balance sheets and are expensed as the services are provided. We also accrue the costs of ongoing clinical trials associated with programs that have been terminated or discontinued for which there is no future economic benefit at the time the decision is made to terminate or discontinue the program. From time to time, we enter into development agreements in which we share expenses with a collaborative partner. We record payments received from our collaborative partners for their share of the development costs as a reduction of research and development expense, except as discussed within Note 20, Collaborative and Other Relationships to these consolidated financial statements. Because an initial indication has been approved for both RITUXAN and GAZYVA, expenses incurred by Genentech in the ongoing development of RITUXAN and GAZYVA are not recorded as research and development expense, but rather reduce our share of profits recorded as a component of unconsolidated joint business revenues. For collaborations with commercialized products, if we are the principal, we record revenue and the corresponding operating costs in their respective line items within our consolidated statements of income. If we are not the principal, we record operating costs as a reduction of revenue. Selling, General and Administrative Expenses Selling, general and administrative expenses are primarily comprised of compensation and benefits associated with sales and marketing, finance, human resources, legal, information technology and other administrative personnel, outside marketing, advertising and legal expenses and other general and administrative costs. Advertising costs are expensed as incurred. For the years ended December 31, 2014, 2013 and 2012, advertising costs totaled $92.9 million, $72.7 million and $54.3 million, respectively. Income Taxes The provision for income taxes includes federal, state, local and foreign taxes. Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences of temporary differences between the financial statement carrying amounts and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which the temporary differences are expected to be recovered or settled. We evaluate the realizability of our deferred tax assets and establish a valuation allowance when it is more likely than not that all or a portion of deferred tax assets will not be realized. All tax effects associated with intercompany transfers of assets within our consolidated group, both current and deferred, are recorded as a prepaid tax or deferred charge and recognized through the consolidated statement of income when the asset transferred is sold to a third party or otherwise recovered through amortization of the asset's remaining economic life. If the asset transferred becomes impaired, for example through the discontinuation of a research program, we will expense any remaining deferred charge or prepaid tax. F- 18 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis and consider various factors, including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in process audit activities and changes in facts or circumstances related to a tax position. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense. Contingencies We are currently involved in various claims and legal proceedings. Loss contingency provisions are recorded if the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount can be reasonably estimated or a range of loss can be determined. These accruals represent management’s best estimate of probable loss. Disclosure also is provided when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision. On a quarterly basis, we review the status of each significant matter and assess its potential financial exposure. Significant judgment is required in both the determination of probability and the determination as to whether an exposure is reasonably estimable. Because of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may change our estimates. These changes in the estimates of the potential liabilities could have a material impact on our consolidated results of operations and financial position. Earnings per Share Basic earnings per share is computed using the two-class method. Under the two-class method, undistributed net income is allocated to common stock and participating securities based on their respective rights to share in dividends. We have determined that our Preferred Stock meets the definition of participating securities. We did not have any shares of Preferred Stock issued and outstanding during 2014, 2013 or 2012. New Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies that we adopt as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard will be effective for us on January 1, 2017. We are currently evaluating the method of adoption and the potential impact that Topic 606 may have on our financial position and results of operations. In June 2014, the FASB issued ASU No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosure. The new standard expands secured borrowing accounting for repurchase- to-maturity transactions and repurchase financings and sets forth new disclosure requirements for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions that are accounted for as secured borrowings. The new standard will be effective for us on April 1, 2015. The adoption of this standard is not expected to have an impact on our financial position or results of operations. 2. Acquisitions TYSABRI On April 2, 2013, we acquired full ownership of all remaining rights to TYSABRI from Elan that we did not already own or control. Upon the closing of the transaction, we made an upfront payment of $3.25 billion to Elan, which was funded from our existing cash, and our collaboration agreement with Elan was terminated. We accounted for this transaction as the acquisition of an asset as we did not acquire any employees from Elan nor did we acquire any significant processes that we did not previously perform or manage under the collaboration agreement. Under the collaboration agreement, we manufactured TYSABRI and collaborated with Elan on the product's marketing, commercial, regulatory, distribution and ongoing development activities. The collaboration agreement was designed to effect an equal sharing of worldwide profits and losses generated by the activities of the collaboration. For additional information related to this collaboration, please read Note 20, Collaborative and Other Relationships to these consolidated financial statements. F- 19 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The $3.25 billion upfront payment was capitalized in the second quarter of 2013 as an intangible asset within our consolidated balance sheet as TYSABRI had reached technological feasibility. We adjusted the value of this intangible asset by $84.4 million related to deferred revenue from two sales-based milestones previously paid by Elan as well as transaction costs. The net intangible asset capitalized was $3,178.3 million. Commencing in the second quarter of 2013, we began amortizing this intangible asset over the estimated useful life using an economic consumption method based on actual and expected revenue generated from the sales of our TYSABRI product, which was 17 years. Following the April 2, 2013 closing of the transaction, we began recording 100% of U.S. revenues, cost of sales and operating expenses related to TYSABRI within our consolidated statements of income. Under the terms of the acquisition agreement, we continued to share TYSABRI profits with Elan on an equal basis until April 30, 2013. We recorded the profit split for the month ended April 30, 2013, as cost of sales within our consolidated statements of income as we controlled TYSABRI effective April 2, 2013. Between May 1, 2013 and April 30, 2014, we made contingent payments to Elan of 12% on worldwide net sales of TYSABRI. Commencing May 1, 2014 and thereafter, we will make contingent payments to Elan of 18% on annual worldwide net sales up to $2.0 billion and 25% on annual worldwide net sales that exceed $2.0 billion. In 2014, the $2.0 billion threshold was pro-rated for the portion of 2014 remaining after the first 12 months expired. Royalty payments to Elan and other third parties are recognized as cost of sales within our consolidated statements of income. Stromedix, Inc. In March 2012, we completed our acquisition of all the outstanding stock of Stromedix, Inc. (Stromedix). The purchase price included a $75.0 million cash payment and up to a maximum of $487.5 million in contingent consideration in the form of development and approval milestones, of which $275.0 million related directly to the development and approval of STX-100 for the treatment of idiopathic pulmonary fibrosis (IPF). The acquisition was funded from our existing cash on hand and was accounted for as the acquisition of a business. In addition to acquiring the outstanding stock of the entity and obtaining the rights to STX-100, we obtained the services of key employees and the rights to a second antibody and an antibody conjugate, which are both in preclinical development. Upon acquisition, we recorded a contingent consideration obligation of $122.2 million representing the fair value of the contingent consideration. This amount was estimated through a valuation model that incorporated industry-based probability- adjusted assumptions relating to the achievement of these milestones and the likelihood of us making payments. Subsequent changes in the fair value of this obligation are recognized as adjustments to contingent consideration and reflected within our consolidated statements of income. We allocated $219.2 million and $48.2 million of the total purchase price to acquired IPR&D and goodwill, respectively. During 2013, we adjusted the goodwill by $4.1 million to establish a deferred tax asset related to our transaction. For additional information related to our fair value of this obligation, please read Note 8, Fair Value Measurements to these consolidated financial statements. Prior to the acquisition of Stromedix, we had an equity interest equal to approximately 5.0% of the company’s total capital stock (on an “as converted” basis) pursuant to a license agreement we entered into with Stromedix in 2007 for the development of the STX-100 product candidate. Based on the fair market value of this equity interest derived from the purchase price, we recognized a gain of approximately $9.0 million in 2012, which was recorded as a component of other income (expense), net within our consolidated statement of income. 3. Gain on Sale of Rights During the third quarter of 2012, we sold all of our rights, including rights to royalties, related to BENLYSTA (belimumab) to a DRI Capital managed fund (DRI). Under the terms of the BENLYSTA sale agreement, we received payments from DRI equal to a multiple of royalties payable by the Human Genome Sciences, Inc. and GlaxoSmithKline plc for the period covering October 2011 to September 2014 and a one-time contingency payment that could be paid to us if the cumulative royalties over the full royalty term exceed an agreed amount. The payments received during 2014, 2013 and 2012 totaled $16.8 million, $24.9 million and $46.8 million, respectively. These payments were recorded as a gain on sale of rights within our consolidated statements of income. The period under which we would receive royalties expired in September 2014. Therefore, we will not receive any additional payments under this agreement. F- 20 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 4. Accounts Receivable Our accounts receivable primarily arise from product sales in the U.S. and Europe and mainly represent amounts due from our wholesale distributors, public hospitals and other government entities. Amounts determined to be uncollectible are charged or written-off against the reserve. To date, our historical reserves and write-offs of accounts receivable have not been significant. The credit and economic conditions within Italy, Spain and Portugal, among other members of the E.U. continue to remain uncertain. Uncertain credit and economic conditions have generally led to a lengthening of time to collect our accounts receivable in some of these countries. In Portugal and select regions in Spain, where our collections have slowed and a significant portion of these receivables are routinely being collected beyond our contractual payment terms and over periods in excess of one year, we have discounted our receivables and reduced related revenues based on the period of time that we estimate those amounts will be paid, to the extent such period exceeds one year, using the country’s market-based borrowing rate for such period. The related receivables are classified at the time of sale as non-current assets. We accrete interest income on these receivables, which is recognized as a component of other income (expense), net within our consolidated statements of income. Our net accounts receivable balances from product sales in selected European countries are summarized as follows: (In millions) Spain .......................................................................................... $ Italy............................................................................................ $ Portugal...................................................................................... $ (In millions) Spain ......................................................................................... $ Italy ........................................................................................... $ Portugal..................................................................................... $ As of December 31, 2014 Current Balance Included within Accounts Receivable, net Non-Current Balance Included within Investments and Other Assets 62.5 51.4 15.1 $ $ $ 5.0 0.5 7.6 $ $ $ As of December 31, 2013 Current Balance Included within Accounts Receivable, net Non-Current Balance Included within Investments and Other Assets 113.3 76.1 10.4 $ $ $ 6.8 2.4 8.2 $ $ $ Total 67.5 51.9 22.7 Total 120.1 78.5 18.6 Approximately $14.2 million and $45.9 million of the total net accounts receivable balances for these countries were overdue more than one year as of December 31, 2014 and 2013, respectively. During the first quarter of 2014, we received approximately $59.6 million in payments from Spain related to receivables aged greater than one year. Pricing of TYSABRI in Italy - AIFA In the fourth quarter of 2011, Biogen Idec Italia SRL, our Italian subsidiary, received a notice from the Italian National Medicines Agency (Agenzia Italiana del Farmaco or AIFA) stating that sales of TYSABRI for the period from mid-February 2009 through mid-February 2011 exceeded by EUR30.7 million a reimbursement limit established pursuant to a Price Determination Resolution (Price Resolution) granted by AIFA in December 2006. In December 2011, based on our interpretation that the Price Resolution by its terms only applied to the first 24 months of TYSABRI sales (which began in mid- February 2007), we filed an appeal against AIFA in administrative court in Rome, Italy seeking a ruling that the reimbursement limit does not apply to the periods beginning in mid-February 2009 and that the position of AIFA is unenforceable. That appeal is pending. Since being notified in the fourth quarter of 2011 that AIFA believed a reimbursement limit was in effect, we deferred revenue on sales of TYSABRI as if the reimbursement limit were in effect for each biannual period beginning in mid- February 2009. F- 21 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) In July 2013, we negotiated an agreement in principle with AIFA's Price and Reimbursement Committee that would have resolved all of AIFA's claims relating to sales of TYSABRI in excess of the reimbursement limit for the periods from February 2009 through January 2013 for an aggregate repayment of EUR33.3 million. The agreement was sent to the Avvocatura Generale dello Stata (Attorney General) for its opinion. As a result of this agreement in principle, we recorded a liability and reduction to revenue of EUR15.4 million at June 30, 2013. That adjustment approximated 50% of the claim related to the period from February 2009 through January 2011 as the likelihood of making a payment to resolve AIFA's claims for that period was then probable and the amount could be estimated. This agreement in principle was not finalized, and AIFA and Biogen Idec Italia SRL remain in discussions about a resolution relating to the claims at issue in that agreement in principle. In October 2014, we proposed a revised settlement for the period from February 2009 through January 2013 of EUR35.6 million to be paid in one payment. We continue to believe that a settlement with AIFA relating to these claims is probable and have retained the EUR15.4 million liability recorded as of June 30, 2013. In June 2014, AIFA approved a resolution, effective for a 24 month term, setting the price for TYSABRI in Italy. The resolution also eliminated the reimbursement limit from February 2013 going forward. As a result, we recognized $53.5 million of TYSABRI revenues related to the periods beginning February 2013 that were previously deferred. An aggregate amount of $77.6 million remains deferred as of December 31, 2014 related to the periods from mid-February 2011 through January 2013. 5. Reserves for Discounts and Allowances As a result of our acquisition of all remaining rights to TYSABRI from Elan, we began recognizing reserves for discounts and allowances for U.S. TYSABRI revenue in the second quarter of 2013. Prior periods included reserves for discounts and allowances for rest of world TYSABRI revenue and worldwide AVONEX revenue. In addition, following our commercial launches of recent products, we began recognizing reserves for discounts and allowances related to these products' revenue. Gross product revenues for 2012 include sales of TYSABRI to Elan under our collaboration agreement, which did not have any corresponding reserves for discounts and allowances. An analysis of the change in reserves is summarized as follows: Discounts Contractual Adjustments Returns Total $ $ $ $ 335.6 1,258.8 (27.2) (933.4) (261.9) 371.9 Contractual Adjustments 196.0 851.4 (16.4) (560.4) (135.0) 335.6 $ $ $ $ 33.7 39.1 13.5 (4.1) (33.1) 49.1 $ $ 416.3 1,645.2 (14.7) (1,237.2) (341.0) 468.6 Returns Total 26.8 22.9 1.1 — (17.1) 33.7 $ $ 237.1 1,110.6 (16.0) (750.1) (165.3) 416.3 (In millions) 2014 Beginning balance ...................................................... $ Current provisions relating to sales in current year .

As of December 31, 2013, our inventory included $93.7 million associated with our ELOCTATE, ALPROLIX and PLEGRIDY programs, which were capitalized in advance of regulatory approval. ELOCTATE, ALPROLIX and PLEGRIDY were approved during 2014. For information on our pre-approval inventory policy, please read Note 1, Summary of Significant Accounting Policies to these consolidated financial statements Amounts written down related to excess, obsolete, unmarketable or other inventory are charged to cost of sales, and totaled $50.6 million, $47.3 million, and $24.8 million for the years ended December 31, 2014, 2013, and 2012, respectively.

The change in amortization of acquired intangible assets for the year ended December 31, 2014 was primarily driven by a $60.2 million increase in amortization of acquired and in-licensed rights and patents as we recognized a full year of expense related to our TYSABRI rights in 2014 versus nine months of expense in 2013, total impairment charges of $50.9 million related to one of our out-licensed patents and one of our IPR&D intangible assets, and lower expected lifetime revenues of AVONEX as discussed further below. Out-licensed Patents Out-licensed patents to third-parties primarily relate to patents acquired in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation in 2003. During 2014, we recorded a charge of $34.7 million related to the impairment of one of our out-licensed patents to reflect a change in its estimated fair value, due to a change in the underlying competitive market for that product, which occurred during the first quarter of 2014. The charge is included in amortization of acquired intangible assets. The fair value of the intangible asset was based on a discounted cash flow calculated using Level 3 fair value measurements and inputs including estimated revenues. Developed Technology Developed technology primarily relates to our AVONEX product, which was recorded in connection with the merger of Biogen, Inc. and IDEC Pharmaceuticals Corporation in 2003. The net book value of this asset as of December 31, 2014, was $599.3 million. We amortize this intangible asset using the economic consumption method based on actual and expected revenues generated from the sales of our AVONEX product. In-process Research and Development (IPR&D) IPR&D represents the fair value assigned to research and development assets that we acquire that have not reached technological feasibility at the date of acquisition. Upon commercialization, we determine the estimated useful life. An analysis of anticipated lifetime revenues and anticipated development costs is performed annually during our long- range planning cycle, which was updated in the third quarter of 2014. This analysis is based upon certain assumptions that we evaluate on a periodic basis, including anticipated future product sales, the expected impact of changes in the amount of development costs and the probabilities of our programs succeeding, the introduction of new products by our competitors and changes in our commercial and pipeline product candidates. F- 24 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) During the third quarter of 2014, we updated the probabilities of success related to the early stage programs acquired through our recent acquisitions. The change in probability of success, combined with a delay in one of the projects, resulted in an impairment loss of $16.2 million in one of our IPR&D assets during 2014. In addition, we have adjusted the value of our contingent consideration liabilities to reflect these lower probabilities of success in connection with these earlier stage programs resulting in a net gain of $49.4 million in the third quarter of 2014. The impairment charge was included in amortization of acquired intangible assets and the gains were recorded in (gain) loss on fair value remeasurement of contingent consideration. The fair values of the intangible assets and contingent consideration liabilities were based on a probability-adjusted discounted cash flow calculation using Level 3 fair value measurements and inputs including estimated revenues and probabilities of success. Acquired and In-licensed Rights and Patents Acquired and in-licensed rights and patents primarily relate to our acquisition of all remaining rights to TYSABRI from Elan. The net intangible asset capitalized related to this acquisition was $3,178.3 million. In the second quarter of 2013, we began amortizing this intangible asset over the estimated useful life using an economic consumption method based on actual and expected revenues generated from the sales of our TYSABRI product. The net book value of this asset as of December 31, 2014 was $2,921.0 million. For a more detailed description of this transaction, please read Note 2, Acquisitions to these consolidated financial statements. The increase in acquired and in-licensed rights and patents during 2014, was primarily related to the $20.0 million contingent payment due to the former owners of Syntonix, which became payable upon the approval of ALPROLIX in the U.S. by the U.S. Food and Drug Administration (FDA) in the first quarter of 2014. We have recorded an additional $7.8 million of acquired in-licensed rights and patents related to this consideration, along with a corresponding deferred tax liability of the same amount. Estimated Future Amortization of Intangible Assets Our amortization expense is based on the economic consumption of the intangible assets. Our most significant intangible assets are related to our AVONEX and TYSABRI products. Annually, during our long-range planning cycle, we perform an analysis of anticipated lifetime revenues of AVONEX and TYSABRI. This analysis is updated whenever events or changes in circumstances would significantly affect the anticipated lifetime revenues of either product. Our most recent long range planning cycle was updated in the third quarter of 2014. Our analysis included an increase in the expected future product revenues of TYSABRI, resulting in a decrease in amortization expense as compared to prior quarters. Our analysis also included a decrease in the expected future product revenues of AVONEX, resulting in an increase in amortization expense as compared to prior quarters. The results of our TYSABRI and AVONEX analyses were impacted by changes in the estimated impact of TECFIDERA, as well as other existing and potential oral and alternative MS formulations, including PLEGRIDY, that may compete with TYSABRI and AVONEX. Based upon this recent analysis, the estimated future amortization for acquired intangible assets is expected to be as follows: (In millions) 2015 .......................................................................................................................................................... $ 2016 .......................................................................................................................................................... 2017 .......................................................................................................................................................... 2018 .......................................................................................................................................................... 2019 ..........................................................................................................................................................

For additional information related to future contingent payments to the former shareholders of Fumapharm AG, please read Note 22, Commitments and Contingencies to these consolidated financial statements. As of December 31, 2014, we had no accumulated impairment losses related to goodwill. 8.

Marketable Equity Securities and Venture Capital Investments Our marketable equity securities represent investments in publicly traded equity securities. Our venture capital investments, which are all Level 3 measurements, include investments in certain venture capital funds, accounted for at fair value, that primarily invest in small privately-owned, venture-backed biotechnology companies. These venture capital investments represented approximately 0.1% and 0.2% of total assets of December 31, 2014 and 2013, respectively.

For additional information related to the changes in fair value, please read Note 7, Intangible Assets and Goodwill to these consolidated financial statements. In connection with our acquisition of Stromedix in March 2012, we recorded a contingent consideration obligation of $122.2 million. As of December 31, 2014 and 2013, the fair value of this contingent consideration obligation was $130.5 million and $140.7 million, respectively. Our most recent valuation was determined based upon probability weighted net cash outflow projections of $419.0 million, discounted using a rate of 3.0%, which is a measure of the credit risk associated with settling the liability. For 2014 compared to 2013, the net decrease in the fair value of this obligation was primarily due changes in the probability and expected timing related to the achievement of certain remaining developmental milestones and in the discount rate. Upon completion of our purchase of the noncontrolling interest in our joint venture investments in Biogen Dompé SRL and Biogen Dompé Switzerland GmbH in September 2011, we recorded a contingent consideration obligation of $38.8 million. As of December 31, 2014 and 2013, the fair value of this contingent consideration obligation was $15.5 million and $31.6 million, respectively. Our most recent valuation was determined based upon probability weighted net cash outflow projections of $22.0 million, discounted using a rate of 2.0%, which is a measure of the credit risk associated with settling the liability. For 2014 compared to 2013, the net decrease in the fair value of this obligation was primarily due to payments of $16.5 million sales-based and regulatory approval milestones. In connection with our acquisition of Biogen Idec International Neuroscience GmbH (BIN), formerly Panima Pharmaceuticals AG (Panima), in December 2010, we recorded a contingent consideration obligation of $81.2 million. As of December 31, 2014 and 2013, the fair value of this contingent consideration obligation was $69.5 million and $108.6 million, respectively. Our most recent valuation was determined based upon probability weighted net cash outflow projections of $362.5 million, discounted using a rate of 3.6%, which is a measure of the credit risk associated with settling the liability. For 2014 compared to 2013, the net decrease in the fair value of this obligation was primarily due to $10.0 million of payments of development milestones, changes in the probability and expected timing related to the achievement of certain remaining developmental milestones and in the discount rate. F- 28 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Acquired IPR&D In connection with our acquisition of Stromedix, we allocated $219.2 million of the total purchase price to acquired IPR&D, which was capitalized as an intangible asset. The amount allocated to acquired IPR&D was based on significant inputs not observable in the market and thus represented a Level 3 fair value measurement. These assets are tested for impairment annually, and whenever events or changes in circumstances indicate that the carrying value of the assets might not be recoverable, until commercialization, after which time the IPR&D is amortized over its estimated economic life. For a more detailed description of this transaction, please read Note 2, Acquisitions to these consolidated financial statements. There were no changes in valuation techniques or transfers between fair value measurement levels during the years ended December 31, 2014 and 2013. During the third quarter 2014, we updated the probabilities of success related to the early stage programs acquired through our recent acquisitions. We have adjusted the value of our contingent consideration liabilities to reflect these changes. For additional information, please read Note 7, Intangible Assets and Goodwill to these consolidated financial statements.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 10. Derivative Instruments Foreign Currency Forward Contracts - Hedging Instruments Due to the global nature of our operations, portions of our revenues are earned in currencies other than the U.S. dollar. The value of revenues measured in U.S. dollars is therefore subject to changes in foreign currency exchange rates. In order to mitigate these changes we use foreign currency forward contracts to lock in exchange rates associated with a portion of our forecasted international revenues. Foreign currency forward contracts in effect as of December 31, 2014 and 2013, had durations of 1 to 15 months and 1 to 18 months, respectively. These contracts have been designated as cash flow hedges and accordingly, to the extent effective, any unrealized gains or losses on these foreign currency forward contracts are reported in accumulated other comprehensive income (loss) (referred to as AOCI in the tables below). Realized gains and losses for the effective portion of such contracts are recognized in revenue when the sale of product in the currency being hedged is recognized. To the extent ineffective, hedge transaction gains and losses are reported in other income (expense), net. The notional value of foreign currency forward contracts that were entered into to hedge forecasted revenues is summarized as follows: Foreign Currency: (In millions) Euro................................................................................................................................ $ Canadian dollar .............................................................................................................. British pound sterling.....................................................................................................

We expect all contracts to be settled over the next 15 months and any amounts in accumulated other comprehensive income (loss) to be reported as an adjustment to revenue. We consider the impact of our and our counterparties’ credit risk on the fair value of the contracts as well as the ability of each party to execute its contractual obligations. As of December 31, 2014 and 2013, credit risk did not change the fair value of our foreign currency forward contracts. The following table summarizes the effect of derivatives designated as hedging instruments on our consolidated statements of income: Net Gains/(Losses) Reclassified from AOCI into Net Income (Effective Portion) Net Gains/(Losses) Recognized into Net Income (Ineffective Portion) For the Years Ended December 31, Location 2014 2013 2012 Location 2014 2013 2012 Revenue ........ $ 6.8 $ (13.2) $ 35.1 Other income (expense) ...... $ (1.5) $ (0.2) $ 4.8 Foreign Currency Forward Contracts - Other Derivatives We also enter into other foreign currency forward contracts, usually with one month durations, to mitigate the foreign currency risk related to certain balance sheet positions. We have not elected hedge accounting for these transactions. The aggregate notional amount of these outstanding foreign currency contracts was $365.2 million and $273.3 million as of December 31, 2014 and 2013, respectively. Net losses of $15.5 million and net gains of $5.2 million and $4.2 million related to these contracts were recognized as a component of other income (expense), net, for years ended December 31, 2014, 2013 and 2012, respectively.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Weston Exit Costs As a result of our decision to relocate our corporate headquarters to Cambridge, Massachusetts, we vacated part of our Weston, Massachusetts facility in the fourth quarter of 2013. We incurred a charge of $27.2 million in connection with this move. This charge represented our remaining lease obligation for the vacated portion of our Weston, Massachusetts facility, net of sublease income expected to be received. The term of our sublease to the vacated portion of our Weston, Massachusetts facility started in January 2014 and will continue through the remaining term of our lease agreement. 12.

The discount is amortized as additional interest expense over the period from issuance through maturity. These notes are senior unsecured obligations. Interest on the notes is payable March 1 and September 1 of each year. The notes may be redeemed at our option at any time at 100% of the principal amount plus accrued interest and a specified make-whole amount. The notes contain a change of control provision that may require us to purchase the notes under certain circumstances. There is also an interest rate adjustment feature that requires us to pay interest at an increased rate on the notes if the credit rating on the notes declines below investment grade. Upon the issuance of the 6.875% Senior Notes due in 2018, we entered into interest rate swap contracts where we received a fixed rate and paid a variable rate. These contracts were terminated in December 2008. Upon termination of these swaps, the carrying amount of the 6.875% Senior Notes due in 2018 was increased by $62.8 million and is being amortized using the effective interest rate method over the remaining life of the Senior Notes and is being recognized as a reduction of interest expense. As of December 31, 2014, $25.3 million remains to be amortized. Notes Payable to Fumedica In connection with our 2006 distribution agreement with Fumedica, we issued notes totaling 61.4 million Swiss Francs which were payable to Fumedica in varying amounts from June 2008 through June 2018. Our remaining note payable to Fumedica had a carrying value of 11.6 million Swiss Francs ($11.7 million) and 14.0 million Swiss Francs ($15.8 million) as of December 31, 2014 and 2013, respectively. Credit Facility In March 2013, we entered into a $750.0 million senior unsecured revolving credit facility, under which we were permitted to draw funds for working capital and general corporate purposes. The terms of the revolving credit facility included a financial covenant that required us to not exceed a maximum debt to EBITDA ratio. In March 2014, the revolving credit facility expired and was not renewed. F- 33 BIOGEN IDEC INC.

These amounts have been calculated under the alternative transition method. As of December 31, 2014, unrecognized compensation cost related to unvested share-based compensation was approximately $198.5 million, net of estimated forfeitures. We expect to recognize the cost of these unvested awards over a weighted-average period of 1.9 years. Share-Based Compensation Plans We have three share-based compensation plans pursuant to which awards are currently being made: (i) the Biogen Idec Inc. 2006 Non-Employee Directors Equity Plan (2006 Directors Plan); (ii) the Biogen Idec Inc. 2008 Amended and Restated Omnibus Equity Plan (2008 Omnibus Plan); and (iii) the Biogen Idec Inc. 1995 Employee Stock Purchase Plan (ESPP). Directors Plan In May 2006, our stockholders approved the 2006 Directors Plan for share-based awards to our directors. Awards granted from the 2006 Directors Plan may include stock options, shares of restricted stock, restricted stock units, stock appreciation rights and other awards in such amounts and with such terms and conditions as may be determined by a committee of our Board of Directors, subject to the provisions of the plan. We have reserved a total of 1.6 million shares of common stock for issuance under the 2006 Directors Plan. The 2006 Directors Plan provides that awards other than stock options and stock appreciation rights will be counted against the total number of shares reserved under the plan in a 1.5-to-1 ratio. F- 37 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Omnibus Plans In June 2008, our stockholders approved the 2008 Omnibus Plan for share-based awards to our employees. Awards granted from the 2008 Omnibus Plan may include stock options, shares of restricted stock, restricted stock units, performance shares, shares of phantom stock, stock appreciation rights and other awards in such amounts and with such terms and conditions as may be determined by a committee of our Board of Directors, subject to the provisions of the plan. Shares of common stock available for issuance under the 2008 Omnibus Plan consist of 15.0 million shares reserved for this purpose, plus shares of common stock that remained available for issuance under our 2005 Omnibus Equity Plan on the date that our stockholders approved the 2008 Omnibus Plan, plus shares that were subject to awards under the 2005 Omnibus Equity Plan which remain unissued upon the cancellation, surrender, exchange or termination of such awards. The 2008 Omnibus Equity Plan provides that awards other than stock options and stock appreciation rights will be counted against the total number of shares available under the plan in a 1.5-to-1 ratio. We have not made any awards pursuant to the 2005 Omnibus Equity Plan since our stockholders approved the 2008 Omnibus Plan, and do not intend to make any awards pursuant to the 2005 Omnibus Equity Plan in the future, except that unused shares under the 2005 Omnibus Equity Plan have been carried over for use under the 2008 Omnibus Plan. Stock Options We currently do not grant stock options to our employees or directors. Outstanding stock options previously granted to our employees and directors generally have a ten-year term and vest over a period of between one and four years, provided the individual continues to serve at Biogen Idec through the vesting dates. Options granted under all plans are exercisable at a price per share not less than the fair market value of the underlying common stock on the date of grant. The estimated fair value of options, including the effect of estimated forfeitures, is recognized over the options’ vesting periods. The fair value of the stock options granted in 2010 was estimated as of the date of grant using a Black-Scholes option valuation model. There were no grants of stock options made in 2014, 2013 and 2012. The expected life of options granted is derived using assumed exercise rates based on historical exercise patterns and represents the period of time that options granted are expected to be outstanding. Expected stock price volatility is based upon implied volatility for our exchange-traded options and other factors, including historical volatility. After assessing all available information on either historical volatility, implied volatility, or both, we have concluded that a combination of both historical and implied volatility provides the best estimate of expected volatility. The risk-free interest rate used is determined by the market yield curve based upon risk-free interest rates established by the Federal Reserve, or non-coupon bonds that have maturities equal to the expected term. The dividend yield of zero is based upon the fact that we have not historically granted cash dividends, and do not expect to issue dividends in the foreseeable future. Stock options granted prior to January 1, 2006 were valued based on the grant date fair value of those awards, using the Black-Scholes option pricing model, as previously calculated for pro-forma disclosures.

Participants may ultimately earn between 0% and 150% of the target number of units granted based on actual stock performance. MSUs awarded to employees in 2014 vest in three equal annual increments beginning on the first anniversary of the grant date, and participants may ultimately earn between 0% and 200% of the target number of units granted based on actual stock performance. The vesting of these awards is subject to the respective employee’s continued employment. The number of MSUs granted represents the target number of units that are eligible to be earned based on the attainment of certain market-based criteria involving our stock price. The number of MSUs earned is calculated at each annual anniversary from the date of grant over the respective vesting periods, resulting in multiple performance periods. Accordingly, additional MSUs may be issued or currently outstanding MSUs may be cancelled upon final determination of the number of awards earned. Compensation expense, including the effect of forfeitures, is recognized over the applicable service period.

The remainder of MSUs granted during 2014 include awards granted in conjunction with our annual awards made in February 2014 and MSUs granted in conjunction with the hiring of employees. These grants reflect the target number of shares eligible to be earned at the time of grant. We value grants of MSUs using a lattice model with a Monte Carlo simulation. This valuation methodology utilizes several key assumptions, including the 60 calendar day average closing stock price on grant date for MSUs awarded prior to 2014, the 30 calendar day average closing stock price on the date of grant for MSUs awarded in 2014, expected volatility of our stock price, risk-free rates of return and expected dividend yield.

AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Cash Settled Performance Units (CSPUs) CSPUs awarded to employees vest in three equal annual increments beginning on the first anniversary of the grant date. The vesting of these awards is subject to the respective employee’s continued employment with such awards settled in cash. The number of CSPUs granted represents the target number of units that are eligible to be earned based on the attainment of certain performance measures established at the beginning of the performance period, which ends on December 31 of each year. Participants may ultimately earn between 0% and 200% of the target number of units granted based on the degree of actual performance metric achievement. Accordingly, additional CSPUs may be issued or currently outstanding CSPUs may be cancelled upon final determination of the number of units earned. CSPUs awarded prior to 2014 are settled in cash based on the 60 calendar day average closing stock price through each vesting date once the actual vested and earned number of units is known. CSPUs awarded in 2014 will be settled in cash based on the 30 calendar day average closing stock price through each vesting date, once the actual vested and earned number of units is known. Since no shares are issued, these awards will not dilute equity. Compensation expense, including the effect of forfeitures, is recognized over the applicable service period.

The remainder of the CSPUs granted in 2014 include awards granted in conjunction with our annual awards made in February 2014 and CSPUs granted in conjunction with the hiring of employees. These grants reflect the target number of shares eligible to be earned at the time of grant. The total cash paid in settlement of CSPUs vested in 2014, 2013 and 2012 totaled $92.8 million, $48.3 million, and $28.7 million, respectively. Performance-vested Restricted Stock Units (PUs) Beginning in the first quarter of 2014, we revised our long term incentive program to include a new type of award granted to certain employees in the form of restricted stock units that may be settled in cash or shares at the sole discretion of the Compensation and Management Development Committee of our Board of Directors. These awards are structured and accounted for the same way as the cash settled performance units, and vest in three equal annual increments beginning on the first anniversary of the grant date. The number of PUs granted represents the target number of units that are eligible to be earned based on the attainment of certain performance measures established at the beginning of the performance period, which ends on December 31 of each year. Participants may ultimately earn between 0% and 200% of the target number of units granted based on the degree of actual performance metric achievement. Accordingly, additional PUs may be issued or currently outstanding PUs may be cancelled upon final determination of the number of units earned. PUs settling in cash are based on the 30 calendar day average closing stock price through each vesting date once the actual vested and earned number of units is known.

Shares of our common stock will be delivered to the employee upon vesting, subject to payment of applicable withholding taxes. RSUs awarded to directors for service on our Board of Directors vest on the first anniversary of the date of grant, provided in each case that the director continues to serve on our Board of Directors through the vesting date.

Of this amount, $29.0 million represents the correction of an error in our accounting that had accumulated over several prior years. We do not consider this correction to be material. Deferred Tax Assets and Liabilities Significant components of our deferred tax assets and liabilities are summarized as follows: (In millions) Deferred tax assets: Tax credits................................................................................................................... $ Inventory, other reserves, and accruals .......................................................................

As of December 31, 2014 and 2013, the total deferred charges and prepaid taxes were $238.9 million and $248.9 million, respectively. F- 42 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) During 2013, we recorded a deferred charge of $203.7 million in connection with an intercompany transfer of the intellectual property for ZINBRYTA. The net book value of this deferred charge as of December 31, 2014 and 2013 was $179.9 million and $193.5 million, respectively. The deferred charge will be amortized to income tax expense over the economic life of the ZINBRYTA program. If the ZINBRYTA program were to be discontinued, we will accelerate the amortization of this deferred charge and record an expense equal to its remaining net book value. Tax Rate A reconciliation between the U.S. federal statutory tax rate and our effective tax rate is summarized as follows: For the Years Ended December 31, 2013 2012 2014 Statutory rate........................................................................................ State taxes ............................................................................................ Taxes on foreign earnings.................................................................... Credits and net operating loss utilization............................................. Purchased intangible assets.................................................................. Manufacturing deduction ..................................................................... Other permanent items......................................................................... Contingent consideration ..................................................................... Other .................................................................................................... Effective tax rate................................................................................ 35.0% 1.2 (9.5) (1.1) 1.2 (1.8) 0.5 (0.4) — 25.1% 35.0% 3.1 (6.7) (2.6) 1.5 (6.6) 0.8 — (0.3) 24.2% 35.0% 0.9 (6.2) (3.5) 1.2 (2.1) (0.4) 0.5 — 25.4% Our effective tax rate for 2014 compared to 2013 increased primarily as a result of the absence of a benefit related to the 2013 change in our uncertain tax position related to our U.S. federal manufacturing deduction and our unconsolidated joint business described below under "Accounting for Uncertainty in Income Taxes", lower current year expenses eligible for the orphan drug credit and a lower relative manufacturing deduction due to unqualified products, partially offset by a higher percentage of our 2014 income being earned outside the U.S. Our effective tax rate for 2013 compared to 2012 decreased primarily as a result of a change in our uncertain tax position related to our U.S. federal manufacturing deduction and our unconsolidated joint business, described below under "Accounting for Uncertainty in Income Taxes", lower intercompany royalties owed by a foreign wholly owned subsidiary to a U.S. wholly owned subsidiary on the international sales of one of our products, the reinstatement of the federal research and development tax credit and the 2012 correction of an error in our deferred tax accounting, which increased our rate in the prior year. These favorable items were partially offset by higher relative earnings in the U.S. from the commercial launch of TECFIDERA, lower orphan drug credits due to reduced expenditures in eligible clinical trials and higher state taxes. As of December 31, 2014, we had net operating losses and general business credit carry forwards for federal income tax purposes of approximately $28.5 million and $6.6 million, respectively, which begin to expire in 2020. Additionally, for state income tax purposes, we had net operating loss carry forwards of approximately $108.1 million, which begin to expire in 2015. For state income tax purposes, we also had research and investment credit carry forwards of approximately $116.8 million, which begin to expire in 2015. For foreign income tax purposes, we had $29.4 million of net operating loss carryforwards, which begin to expire in 2020. In assessing the realizability of our deferred tax assets, we have considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, under the applicable financial reporting standards, we are allowed to consider the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. Our estimates of future taxable income take into consideration, among other items, our estimates of future income tax deductions related to the exercise of stock options. Based upon the level of historical taxable income and income tax liability and projections for future taxable income over the periods in which the deferred tax assets are utilizable, we believe it is more likely than not that we will realize the benefits of the deferred tax assets of our wholly owned subsidiaries. In the event that actual results differ from our estimates or we adjust our estimates in future periods, we may need to establish a valuation allowance, which could materially impact our financial position and results of operations. F- 43 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) As of December 31, 2014, undistributed foreign earnings of non-U.S. subsidiaries included in consolidated retained earnings and other basis differences aggregated approximately $4.6 billion. We intend to reinvest these earnings indefinitely in operations outside the U.S. The residual U.S. tax liability, if cumulative amounts were repatriated, would be between $1.5 billion to $1.6 billion as of December 31, 2014. Accounting for Uncertainty in Income Taxes A reconciliation of the beginning and ending amount of our unrecognized tax benefits is summarized as follows: (In millions) Balance at January 1,................................................................................ $ Additions based on tax positions related to the current period.............. Additions for tax positions of prior periods........................................... Reductions for tax positions of prior periods......................................... Statute expirations..................................................................................

We file income tax returns in the U.S. federal jurisdiction, various U.S. states, and foreign jurisdictions. With few exceptions, including the proposed disallowance we discuss below, we are no longer subject to U.S. federal tax examination for years before 2013 or state, local, or non-U.S. income tax examinations for years before 2004. Included in the balance of unrecognized tax benefits as of December 31, 2014, 2013 and 2012 are $53.6 million, $32.5 million and $109.5 million (net of the federal benefit on state issues), respectively, of unrecognized tax benefits that, if recognized, would affect the effective income tax rate in future periods. We recognize potential interest and penalties accrued related to unrecognized tax benefits in income tax expense. In 2014, we recognized a net interest expense of $4.1 million. During 2013, we recognized net interest expense of $4.5 million. In 2012, we recognized a net interest expense of approximately $0.1 million. We have accrued approximately $17.6 million and $11.3 million for the payment of interest as of December 31, 2014 and 2013, respectively. In December 2014, we received a notice of assessment from the Danish Tax Authority (SKAT) for fiscal 2009, regarding withholding taxes and the treatment of certain intercompany transactions involving our Danish affiliate and another of our affiliates. The audits of our tax filings for 2010 through 2013 are not completed but have been prepared in a manner consistent with prior filings, with similar transactions, which may result in an assessment for those years. The total amount assessed for 2009 is $51.1 million, including interest. For all periods potentially under dispute, we believe that positions taken in our tax filings are valid and we are contesting the assessment vigorously. Federal Uncertain Tax Positions During 2013, we received updated technical guidance from the IRS concerning our current and prior year filings and calculation of our U.S. federal manufacturing deduction and overall tax classification of our unconsolidated joint business. Based on this guidance we reevaluated the level of our unrecognized benefits related to uncertain tax positions, and recorded a $49.8 million income tax benefit. This benefit is for a previously unrecognized position and relates to years 2005 through 2012. We recorded an offsetting expense of $11.3 million for non-income based state taxes, which is recorded in other income (expense) within our consolidated statements of income. In October 2011, in conjunction with our examination, the IRS proposed a disallowance of approximately $130 million in deductions for tax years 2007, 2008 and 2009 related to payments for services provided by our wholly owned Danish subsidiary located in Hillerød, Denmark. We believe that these items represent valid deductible business expenses and are vigorously defending our position. We have initiated a mutual agreement procedure between the IRS and SKAT for the years 2001 through 2009, in an attempt to reach agreement on the issue. In addition, we have applied for a bilateral advanced pricing agreement for the years 2010 through 2014 to resolve similar issues for the subsequent years. F- 44 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) During the year ended December 31, 2014, the net effect of adjustments to our uncertain tax positions was a net expense of $2.0 million. It is reasonably possible that we will adjust the value of our uncertain tax positions related to our unconsolidated joint business and certain transfer pricing issues as we receive additional information from various taxing authorities, including reaching settlements with the authorities. In addition, the IRS and other national tax authorities routinely examine our intercompany transfer pricing with respect to intellectual property related transactions and it is possible that they may disagree with one or more positions we have taken with respect to such valuations. 18. Other Consolidated Financial Statement Detail Supplemental Cash Flow Information Supplemental disclosure of cash flow information for the years ended December 31, 2014, 2013 and 2012, is as follows: (In millions) Cash paid during the year for: For the Years Ended December 31, 2013 2012 2014 Interest......................................................................................... $ Income taxes ............................................................................... $ 41.2 1,163.2 $ $ 53.6 643.2 $ $ 65.4 526.6 Non-cash Investing and Financing Activity In the fourth quarter of 2014, we accrued $250.0 million upon reaching $4.0 billion in total cumulative sales of Fumapharm Products. The amount, net of tax benefit, was accounted for as an increase to goodwill in accordance with the accounting standard applicable to business combinations when we acquired Fumapharm and is expected to be paid in the first quarter of 2015. For additional information related to this transaction, please read Note 22, Commitment and Contingencies to these consolidated financial statements. In July and November 2013, the construction of two office buildings in Cambridge, Massachusetts was completed and we started leasing the facilities. Upon completion of the construction of the buildings, we determined that we were no longer considered the owner of the buildings because we did not have any unusual or significant continuing involvement. Consequently, we derecognized the buildings and their associated financing obligation of approximately $161.5 million from our consolidated balance sheet. In March 2012, upon completion of our acquisition of Stromedix, we recorded $219.2 million of in-process research and development and $48.2 million of goodwill. In addition, we also recorded a contingent consideration obligation of $122.2 million.

Investments in Variable Interest Entities Consolidated Variable Interest Entities Our consolidated financial statements include the financial results of variable interest entities in which we are the primary beneficiary. Knopp In August 2010, we entered into a license agreement with Knopp Neurosciences, Inc. (Knopp), a subsidiary of Knopp Holdings, LLC, for the development, manufacture and commercialization of dexpramipexole. Under the terms of the license agreement we made a $26.4 million upfront payment and agreed to pay Knopp development and sales-based milestone payments as well as royalties on future commercial sales. In addition, we also purchased 30.0% of the Class B common shares of Knopp for $60.0 million. Upon entering into the license agreement, we began consolidating the results of Knopp as we determined that we had the power through the license agreement to direct the activities that most significantly impacted its economic performance and were therefore its primary beneficiary. At the end of December 2012, we learned that a Phase 3 trial investigating dexpramipexole in people with amyotrophic lateral sclerosis (ALS) did not meet its primary endpoint and failed to show efficacy in its key secondary endpoints. Based on these results, we discontinued development of dexpramipexole in ALS. In 2013, we terminated our license agreement and executed our put option on our Class B common shares. We deconsolidated the results of Knopp upon termination of the license agreement. During the year ended December 31, 2012, $113.0 million of expense was reflected within our consolidated statements of income. F- 46 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Neurimmune SubOne AG In 2007, we entered into a collaboration agreement with Neurimmune SubOne AG (Neurimmune), a subsidiary of Neurimmune AG, for the development and commercialization of antibodies for the treatment of Alzheimer’s disease. Neurimmune conducts research to identify potential therapeutic antibodies and we are responsible for the development, manufacturing and commercialization of all products. Our anti-amyloid beta antibody, BIIB037 program, for Alzheimer’s disease resulted from this collaboration. In December 2014, we reported positive interim data from the Phase 1b trial of BIIB037. Based upon our current development plans, we may pay Neurimmune up to $335.0 million in remaining milestone payments, of which $60.0 million is due upon the initiation of a late stage clinical trial. We may also pay royalties in the low- to-mid-teens on sales of any resulting commercial products. We determined that we are the primary beneficiary of Neurimmune because we have the power through the collaboration to direct the activities that most significantly impact the entity’s economic performance and are required to fund 100% of the research and development costs incurred in support of the collaboration agreement. Accordingly, we consolidate the results of Neurimmune. Amounts that are incurred by Neurimmune for research and development expenses in support of the collaboration that we reimburse are reflected in research and development expense in our consolidated statements of income. In the second quarter of 2014, we recorded a $10.0 million milestone payment in connection with the achievement of certain clinical goals in the Phase 1 trial of our BIIB037 program for Alzheimer’s disease, which was reflected as a charge to noncontrolling interests, net of tax, within our consolidated statements of income. Future milestone payments will be reflected within our consolidated statements of income as a charge to the noncontrolling interest, net of tax, when such milestones are achieved. During the years ending December 31, 2014, 2013 and 2012, $44.1 million, $27.2 million and $13.3 million, respectively, of expense was reflected within our consolidated statements of income. The assets and liabilities of Neurimmune are not significant to our financial position or results of operations as it is a research and development organization. We have provided no financing to Neurimmune other than previously contractually required amounts. Ataxion, Inc. In February 2014, we paid $1.6 million for preferred stock of Ataxion, Inc. (Ataxion) and entered into an option agreement which gives us the right to purchase all outstanding shares of Ataxion at any time until 30 days after delivery of a Phase 1 clinical trial study report. Ataxion is a discovery-stage biopharmaceutical company developing product candidates focused on a group of orphan genetic disorders referred to as hereditary ataxias. We committed to make additional investments in Ataxion's preferred shares of up to $6.2 million if certain development milestones are achieved. In December 2014, we made an additional investment of $2.3 million in Ataxion as the first development milestone was achieved. If we exercise our option to purchase the outstanding shares of Ataxion, we could pay additional amounts upon achievement of clinical and commercial milestones. In the Ataxion relationship, through our fixed price option to purchase the company, purchases of equity and presence on the program advisory committee, we are deemed to be the primary beneficiary of Ataxion, a variable interest entity. Therefore, we consolidate the results of Ataxion. As part of the initial consolidation of Ataxion, we recorded an IPR&D intangible asset of $3.5 million and assigned that amount to minority interest within our shareholders' equity. The assets and liabilities of Ataxion are not significant to our financial position or results of operations as it is a research and development organization. We have provided no financing to Ataxion other than contractually required amounts. Unconsolidated Variable Interest Entities We have relationships with other variable interest entities that we do not consolidate as we lack the power to direct the activities that significantly impact the economic success of these entities. These relationships include investments in certain biotechnology companies. As of December 31, 2014 and 2013, the total carrying value of our investments in biotechnology companies that we have determined to be variable interest entities, but do not consolidate as we do not have the power to direct their activities, totaled $7.9 million and $5.5 million, respectively. Our maximum exposure to loss related to these variable interest entities is limited to the carrying value of our investments. We have entered into research collaborations with certain variable interest entities where we are required to fund certain development activities. These development activities are included in research and development expense within our consolidated statements of income, as they are incurred. We have provided no financing to these variable interest entities other than previously contractually required amounts. F- 47 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 20. Collaborative and Other Relationships In connection with our business strategy, we have entered into various collaboration agreements which provide us with rights to develop, produce and market products using certain know-how, technology and patent rights maintained by our collaborative partners. Terms of the various collaboration agreements may require us to make milestone payments upon the achievement of certain product research and development objectives and pay royalties on future sales, if any, of commercial products resulting from the collaboration. Depending on the collaborative arrangement, we may record funding receivables or payable balances with our partners, based on the nature of the cost-sharing mechanism and activity within the collaboration. Our significant collaboration arrangements are discussed below. Genentech (Roche Group) We collaborate with Genentech on the development and commercialization of RITUXAN. In addition, in the U.S., we share operating profits and losses relating to GAZYVA with Genentech. The Roche Group and its sub-licensees maintain sole responsibility for the development, manufacturing and commercialization of GAZYVA in the U.S. Our collaboration agreement will continue in effect until we mutually agree to terminate the collaboration, except that if we undergo a change in control, as defined in the collaboration agreement, Genentech has the right to present an offer to buy the rights to RITUXAN and we must either accept Genentech’s offer or purchase Genentech’s rights on the same terms as its offer. Genentech will also be deemed concurrently to have purchased our rights to any other anti-CD20 products in development in exchange for a royalty and our rights to GAZYVA in exchange for the compensation described in the table below. Our collaboration with Genentech was created through a contractual arrangement and not through a joint venture or other legal entity. RITUXAN Genentech is responsible for the worldwide manufacturing of RITUXAN. Development and commercialization rights and responsibilities under this collaboration are divided as follows: U.S. We share with Genentech co-exclusive rights to develop, commercialize and market RITUXAN in the U.S. Canada We and Genentech have assigned our rights under our collaboration agreement with respect to Canada to Roche. Outside the U.S. and Canada We have granted Genentech exclusive rights to develop, commercialize and market RITUXAN outside the U.S. and Canada. Under the terms of separate sublicense agreements between Genentech and Roche, development and commercialization of RITUXAN outside the U.S. and Canada is the responsibility of Roche and its sublicensees. We do not have any direct contractual arrangements with Roche or it sublicensees. Under the terms of the collaboration agreement, Roche pays us royalties between 10% and 12% on sales of RITUXAN outside the U.S. and Canada, with the royalty period lasting 11 years from the first commercial sale of RITUXAN on a country- by-country basis. The royalty periods for the substantial portion of the royalty-bearing sales in the rest of world markets expired during 2012 and 2013. We expect future revenue on sales of RITUXAN in the rest of world will be limited to our share of pre- tax co-promotion profits in Canada. GAZYVA Prior to approval, we recognized 35% of the development and commercialization expenses as research and development expense and selling, general and administrative expense, respectively, in our consolidated statements of income. After GAZYVA was approved by the FDA in the fourth quarter of 2013, we began to recognize our share of the development and commercialization expenses as a reduction of our share of pre-tax profits in revenues from unconsolidated joint business. Commercialization of GAZYVA will impact our percentage of the co-promotion profits for RITUXAN, as summarized in the table below. F- 48 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Ocrelizumab Genentech is solely responsible for further development and commercialization of ocrelizumab, a humanized anti-CD20 monoclonal antibody currently in development for MS, and funding future costs. Genentech cannot develop ocrelizumab in CLL, NHL or RA. We will receive tiered royalties between 13.5% and 24% on U.S. sales of ocrelizumab if approved for commercial sale by the FDA. Commercialization of ocrelizumab does not impact the percentage of the co-promotion profits we receive for RITUXAN. Profit-sharing Formula RITUXAN Our current pretax co-promotion profit-sharing formula provides for a 30% share on the first $50.0 million of co- promotion operating profits earned each calendar year. Our share of annual co-promotion profits in excess of $50.0 million varies, as summarized in the table below, upon the following events: Until GAZYVA First Non-CLL FDA Approval.......................................................................................... After GAZYVA First Non-CLL FDA Approval until First GAZYVA Threshold Date.............................. After First GAZYVA Threshold Date until Second GAZYVA Threshold Date.......................................... After Second GAZYVA Threshold Date..................................................................................................... 40.0% 39.0% 37.5% 35.0% First Non-CLL GAZYVA FDA Approval means the FDA’s first approval of GAZYVA in an indication other than CLL. First GAZYVA Threshold Date means the earlier of (1) the date of the First Non-CLL GAZYVA FDA approval if U.S. gross sales of GAZYVA for the preceding consecutive 12 month period were at least $150.0 million or (2) the first day of the calendar quarter after the date of the First Non-CLL GAZYVA FDA Approval that U.S. gross sales of GAZYVA within any consecutive 12 month period have reached $150.0 million. Second GAZYVA Threshold Date means the first day of the calendar quarter after U.S. gross sales of GAZYVA within any consecutive 12 month period have reached $500.0 million. The Second GAZYVA Threshold Date can be achieved regardless of whether GAZYVA has been approved in a non-CLL indication. In addition, should the FDA approve an anti-CD20 product other than ocrelizumab or GAZYVA that is acquired or developed by Genentech and subject to the collaboration agreement, our share of the co-promotion operating profits would be between 30% and 38% based on certain events. GAZYVA Our current pretax profit-sharing formula provides for a 35% share on the first $50.0 million of operating profits earned each calendar year. Our share of annual profits in excess of $50.0 million varies, as summarized in the table below, upon the following events: Until First GAZYVA Threshold Date.......................................................................................................... After First GAZYVA Threshold Date until Second GAZYVA Threshold Date.......................................... After Second GAZYVA Threshold Date..................................................................................................... 39.0% 37.5% 35.0% Our share of operating losses on GAZYVA is 35%. Unconsolidated Joint Business Revenues During the first quarter of 2013, we reduced our share of RITUXAN revenues from unconsolidated joint business by approximately $49.7 million, of which revenue on sales in the rest of world for RITUXAN was reduced by $41.2 million and pre-tax profits in the U.S. were reduced by $8.5 million, to reflect our share of the royalties and interest awarded to Hoechst in its arbitration with Genentech. F- 49 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Revenues from unconsolidated joint business are summarized as follows: (In millions) Biogen Idec’s share of pre-tax profits in the U.S. for RITUXAN and GAZYVA (1)............................................................................... $ Reimbursement of selling and development expenses in the U.S. for RITUXAN....................................................................................

For the Years Ended December 31, 2014 2013 2012 1,114.1 $ 1,085.2 $ 1,031.7 3.0 78.3 2.1 38.7 1.6 104.6 1,137.9 Total unconsolidated joint business revenues............................. $ 1,195.4 $ 1,126.0 $ (1) GAZYVA sales began in the fourth quarter of 2013. In 2014, 2013, and 2012, the 40% profit-sharing threshold was met during the first quarter. Prior to regulatory approval, we record our share of the expenses incurred by the collaboration for the development of anti-CD20 products in research and development expense in our consolidated statements of income. We incurred $25.7 million and $35.4 million in development expense for the years ended December 31, 2013 and 2012, respectively. After an anti-CD20 product is approved, we record our share of the development expenses related to that product as a reduction of our share of pre- tax profits in revenues from unconsolidated joint business. Elan On April 2, 2013, we acquired full ownership of all remaining rights to TYSABRI from Elan that we did not already own or control. Upon the closing of the transaction, our collaboration agreement with Elan was terminated. For additional information related to this transaction, please read Note 2, Acquisitions to these consolidated financial statements. We previously collaborated with Elan on the development, manufacture and commercialization of TYSABRI. Under the terms of our collaboration agreement, we manufactured TYSABRI and collaborated with Elan on the product’s marketing, commercial distribution and ongoing development activities. The agreement was designed to effect an equal sharing of profits and losses generated by the activities of our collaboration. Under the agreement, however, once sales of TYSABRI exceeded specific thresholds, Elan was required to make milestone payments to us in order to continue sharing equally in the collaboration’s results. In the U.S., we previously sold TYSABRI to Elan who then sold the product to third party distributors. Our sales price to Elan in the U.S. was set prior to the beginning of each quarterly period to effect an approximate equal sharing of the gross profit between Elan and us. We recognized revenue for sales in the U.S. of TYSABRI upon Elan’s shipment of the product to the third party distributors, at which time all revenue recognition criteria had been met. We incurred manufacturing and distribution costs, research and development expenses, commercial expenses, and general and administrative expenses related to TYSABRI. We recorded these expenses to their respective line items within our consolidated statements of income when they were incurred. Research and development and sales and marketing expenses were shared equally with Elan and the reimbursement of these expenses was recorded as reductions of the respective expense categories. During the years ended December 31, 2013 and 2012, we recorded $11.7 million and $43.7 million, respectively, as reductions of research and development expense resulting from reimbursements from Elan. In addition, for the years ended December 31, 2013 and 2012, we recorded $20.6 million and $99.9 million, respectively, as reductions of selling, general and administrative expense resulting from reimbursements from Elan. In the rest of world, we previously were responsible for distributing TYSABRI to customers and were primarily responsible for all operating activities. Generally, we recognized revenue for sales of TYSABRI in the rest of world at the time of product delivery to our customers. We made payments to Elan which effected an equal sharing of rest of world collaboration operating profits. These payments also included the reimbursement we paid to Elan for half of the third-party royalties that Elan paid on behalf of the collaboration relating to rest of world sales. These amounts were reflected in the collaboration profit sharing line in our consolidated statements of income. For the years ended December 31, 2013 and 2012, $85.4 million and $317.9 million, respectively, was reflected in the collaboration profit sharing line for our collaboration with Elan. F- 50 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Acorda In 2009, we entered into a collaboration and license agreement with Acorda Therapeutics, Inc. (Acorda) to develop and commercialize products containing fampridine in markets outside the U.S. We also have responsibility for regulatory activities and the future clinical development of related products in those markets. In July 2011, the EC granted a conditional marketing authorization for fampridine in the E.U., under the trade name FAMPYRA, which triggered a $25.0 million milestone payment. This payment was made to Acorda in 2011 and was capitalized as an intangible asset. Under the terms of the collaboration and license agreement, we pay Acorda tiered royalties based on the level of ex-U.S. net sales. We may pay up to $375.0 million of additional milestone payments to Acorda, based on the successful achievement of certain regulatory and commercial milestones. The next expected milestone would be $15.0 million, due if ex-U.S. net sales reach $100.0 million over a period of four consecutive quarters. We will capitalize these additional milestones as intangible assets upon achievement of the milestone which will then be amortized utilizing an economic consumption model and recognized as amortization of acquired intangible assets. Royalty payments are recognized as a cost of goods sold. In connection with the collaboration and license agreement, we have also entered into a supply agreement with Acorda for the commercial supply of FAMPYRA. This agreement is a sublicense arrangement of an existing agreement between Acorda and Alkermes, who acquired Elan Drug Technologies, the original party to the license with Acorda. During the years ending December 31, 2014, 2013 and 2012, total cost of sales related to royalties and commercial supply of FAMPRYA reflected within our consolidated statement of income were $29.2 million, $24.3 million and $20.2 million, respectively. Swedish Orphan Biovitrum AB In January 2007, we acquired 100% of the stock of Syntonix. Syntonix had previously entered into a collaboration agreement with Swedish Orphan Biovitrum AB (Sobi) to jointly develop and commercialize Factor VIII and Factor IX hemophilia products, including ELOCTATE and ALPROLIX. In February 2010, we restructured the collaboration agreement and assumed full development responsibilities and costs, as well as manufacturing rights. In addition, the cross-royalty rates were reduced and commercial rights for certain territories were changed. As a result, we now have commercial rights for North America (the Biogen Idec North America Territory) and for rest of the world markets outside of Europe, Russia, Turkey and certain countries in the Middle East (the Biogen Idec Direct Territory). Subject to the exercise of an option right that Sobi controls, Sobi will have commercial rights in Europe, Russia, Turkey and certain countries in the Middle East (the Sobi Territory). The collaboration agreement was amended and restated in April 2014. (References to the collaboration agreement refer to the amended and restated collaboration agreement). Under the terms of the collaboration agreement, following our submission of a MAA to the EMA for each product developed under the collaboration, Sobi may exercise an option to take over final regulatory approval, pre-launch and commercialization activities in the Sobi Territory by making a payment into escrow of $10.0 million per product. In November 2014, Sobi exercised its option to assume development and commercialization of ELOCTA (trade name for ELOCTATE in the E.U.) within the Sobi Territory and deposited $10.0 million to be held in escrow. Upon EMA regulatory approval of each such product, Sobi will be liable to reimburse us 50% of the sum of all shared manufacturing and development expenses incurred by us from October 1, 2009 through the earlier of the date on which Sobi is registered as the marketing authorization holder for the applicable product or 90 days post-regulatory approval, as well as 100% of certain development expenses incurred exclusively for the benefit of the Sobi Territory (the Opt-In Consideration). Through December 31, 2014, approximately $175 million in expenditures for ELOCTA may be reimbursable by Sobi under the collaboration agreement due to its election to assume development and commercialization of ELOCTA within the Sobi Territory and approximately $150 million in expenditures for ALPROLIX may be reimbursable by Sobi under the collaboration agreement if Sobi should exercise its option right with respect to ALPROLIX. The escrow payment made with respect to each product will be applied to the amount of the Opt-In Consideration to be reimbursed by Sobi. To effect Sobi’s reimbursement to us for the Opt-In Consideration exceeding the escrow payment for the applicable product, the cross-royalty structure for direct sales in each company’s respective territories will be adjusted until the Opt-In Consideration is paid in full (the Reimbursement Period). The mechanism for reimbursement is outlined in the table below. F- 51 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Under the collaboration agreement, amounts are payable as follows: Royalty and Net Revenue Share Rates: Sobi rate to Biogen Idec on net sales in the Sobi Territory Biogen Idec rate to Sobi on net sales in the Biogen Idec North America Territory Biogen Idec rate to Sobi on net sales in the Biogen Idec Direct Territory Biogen Idec rate to Sobi on net revenue(1) from the Biogen Idec Distributor Territory(2) Method Royalty Royalty Royalty Net Revenue Share Rates should Sobi exercise its option right (3) Rate prior to 1st commercial sale in the Sobi Territory: Base Rate following 1st commercial sale in the Sobi Territory: N/A 2% 2% 10% 10 to 12% 10 to 12% 15 to 17% 50% Rate during the Reimbursement Period: Base Rate plus 5% Base Rate less 5% Base Rate less 5% Base Rate less 15% (1) Net revenue represents Biogen Idec’s pre-tax receipts from third-party distributors, less expenses incurred by Biogen Idec in the conduct of commercialization activities supporting the distributor activities. (2) The Biogen Idec Distributor Territory represents Biogen Idec territories where sales are derived utilizing a third-party distributor. (3) A credit will be issued to Sobi against its reimbursement of the Opt-in Consideration in an amount equal to the difference in the rate paid by Biogen Idec to Sobi on sales in the Biogen Idec territories for certain periods prior to the first commercial sale in the Sobi Territory versus the rate that otherwise would have been payable on such sales. If the reimbursement of the Opt-in Consideration has not been achieved within six years of the first commercial sale of such product, we maintain the right to require Sobi to pay any remaining balances due to us within 90 days of the six year anniversary date of the first commercial sale. Should Sobi not exercise its option right with respect to ALPROLIX or should Sobi terminate the collaboration agreement with respect to one or both products, we will obtain full worldwide development and commercialization rights for such affected products and we will be obligated to pay royalties to Sobi subject to separate terms, as defined in the collaboration agreement. In addition, if EMA approval for any product is not granted within 18 months of the applicable EMA filing date, Sobi shall have the right to require that the escrow payment be refunded and revoke its option right for such product. AbbVie Biotherapeutics, Inc. We have a collaboration agreement with AbbVie Biotherapeutics, Inc., a subsidiary of AbbVie, Inc. (AbbVie) aimed at advancing the development and commercialization of ZINBRYTA in MS. Under the agreement, development and commercialization costs and profits in North America and the E.U. are shared equally and we are responsible for the manufacture of ZINBRYTA. Based upon our current development plans, we may incur up to an additional $60.0 million of payments upon achievement of development and commercial milestones related to the development of ZINBRYTA, of which $16.0 million will be due upon filing with the FDA and EMA. A summary of activity related to this collaboration is as follows: (In millions) Total development expense incurred by the collaboration...................... $ Biogen Idec’s share of development expense reflected within our consolidated statements of income.......................................................... $ For the Years Ended December 31, 2013 2014 117.8 67.4 $ $ 133.4 71.0 $ $ 2012 128.0 65.6 F- 52 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Isis Pharmaceuticals, Inc. Long-Term Strategic Research Collaboration In September 2013, we entered into a six year research collaboration with Isis Pharmaceuticals Inc. (Isis) under which both companies collaborate to perform discovery level research and then develop and commercialize antisense or other therapeutics for the treatment of neurological disorders. Under the collaboration, Isis will perform research on a set of neurological targets identified within the agreement. Once the research has reached a specific stage of development, we will make the determination whether antisense is the preferred approach to develop a therapeutic candidate or whether another modality is preferred. If antisense is selected, Isis will continue development and identify a product candidate. If another modality is used, we will assume the responsibility for identifying a product candidate and developing it. Under the terms of this agreement, we paid Isis an upfront amount of $100.0 million. Of this payment, we recorded prepaid research and discovery services of approximately $25.0 million, representing the value of the Isis full time equivalent employee resources which are required by the collaboration to provide research and discovery services to us over the next six years. The remaining $75.0 million of the upfront payment was recorded as research and development expense in the third quarter of 2013, the period in which we entered into the collaboration, as it represents the purchase of intellectual property that has not reached technological feasibility. Isis is also eligible to receive milestone payments, license fees and royalty payments for all product candidates developed through this collaboration, with the specific amount dependent upon the modality of the product candidate advanced by us. During 2014, we made payments of $20.0 million to Isis related to the advancement of ISIS-BIIB3Rx to treat a neurodegenerative disease. For non-ALS antisense product candidates, Isis will be responsible for global development through the completion of a Phase 2 trial and we will provide advice on the clinical trial design and regulatory strategy. For ALS antisense product candidates, we are responsible for global development, clinical trial design and regulatory strategy. We have an option to license a product candidate until completion of the Phase 2 trial. If we exercise our option, we will pay Isis up to a $70.0 million license fee and assume global development, regulatory and commercialization responsibilities. Isis could receive additional milestone payments upon the achievement of certain regulatory milestones of up to $130.0 million, plus additional amounts related to the cost of clinical trials conducted by Isis under the collaboration, and royalties on future sales if we successfully develop the product candidate after option exercise. For product candidates using a different modality, we will be responsible for global development through all stages and will owe Isis up to $90.0 million upon the achievement of certain regulatory milestones. Product Collaborations In December, June and January 2012, we entered into three separate exclusive, worldwide option and collaboration agreements with Isis Pharmaceuticals, Inc. (Isis) under which both companies will develop and commercialize antisense therapeutics for up to three gene targets, Isis’ product candidates for the treatment of myotonic dystrophy type 1 (DM1), and the antisense investigational candidate, ISIS-SMNRx for the treatment of spinal muscular atrophy (SMA), respectively. Antisense Therapeutics Under the terms of the December 2012 agreement, for up to three gene targets we provided Isis with an upfront payment of $30.0 million and will make potential additional payments, prior to licensing, of up to $10.0 million based on the development of the selected product candidate as well as a mark-up of the cost estimate of the Phase 1 and Phase 2 trials. Isis will be responsible for global development of any product candidate through the completion of a Phase 2 trial and we will provide advice on the clinical trial design and regulatory strategy. We have an option to license the product candidate until completion of the Phase 2 trial. If we exercise our option, we will pay Isis up to a $70.0 million license fee and assume global development, regulatory and commercialization responsibilities. Isis could receive up to another $130.0 million in milestone payments upon the achievement of certain regulatory milestones as well as royalties on future sales if we successfully develop the product candidate after option exercise. F- 53 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) ISIS-DMPKRx Under the terms of the June 2012 agreement for the DM1 candidate, we provided Isis with an upfront payment of $12.0 million and will make potential additional payments, prior to licensing, of up to $59.0 million based on the development of the selected product candidate. During 2014 and 2013, we made payments of $14.0 million and $10.0 million, respectively, to Isis related to the selection and advancement of ISIS-DMPKRx to treat DM1. Isis will be responsible for global development of any product candidate through the completion of a Phase 2 trial and we will provide advice on the clinical trial design and regulatory strategy. We also have an option to license the product candidate until completion of the Phase 2 trial. If we exercise our option, we will pay Isis up to a $70.0 million license fee and assume global development, regulatory and commercialization responsibilities. Isis could receive up to another $130.0 million in milestone payments upon the achievement of certain regulatory milestones as well as royalties on future sales if we successfully develop the product candidate after option exercise. During the years ending December 31, 2014, 2013 and 2012, $10.9 million, $11.2 million and $22.0 million, respectively, were reflected within our consolidated statements of income. ISIS-SMNRx Under the terms of the January 2012 agreement for the antisense investigation drug, ISIS-SMNRx, we paid Isis $29.0 million as an upfront payment. During 2014, we amended the agreement to adjust the amount of potential additional payments and terms of the exercise of our opt-in right to license ISIS-SMNRx. Consistent with the initial agreement, Isis remains responsible for conducting the pivotal/Phase 3 trials. We are providing input on the clinical trial design and regulatory strategy for the development of ISIS- SMNRx. During 2014, we made clinical trial payments of $57.3 million to Isis related to the advancement of the program. We are recognizing these payments as research and development expenses as the trial costs are incurred. We may exercise our opt-in right upon completion of and data review of the first successful Phase 2/3 trial or completion of both Phase 2/3 trials. An amendment in December 2014 provided for additional opt-in scenarios, based on the filing or the acceptance of a new drug application or marketing authorization application with the FDA or EMA. Under the amended collaboration agreement, we may pay Isis up to approximately $325.0 million in a license fee and payments, including $100.0 million in payments associated with the clinical development of ISIS-SMNRx prior to licensing, a license fee and $150.0 million in milestone payments upon the achievement of certain regulatory milestones as well as royalties on future sales of ISIS-SMNRx if we successfully develop ISIS-SMNRx after option exercise. During the years ending December 31, 2014, 2013 and 2012, $27.7 million, $13.6 million and $39.6 million, respectively, were reflected within our consolidated statements of income. Eisai Co., Ltd. BAN2401 and E2609 Collaboration On March 4, 2014, we entered into a collaboration agreement with Eisai Co., Ltd. (Eisai) to jointly develop and commercialize two Eisai product candidates for the treatment of Alzheimer’s disease, BAN2401, a monoclonal antibody that targets amyloid-beta aggregates, and E2609, a BACE inhibitor, (Eisai Collaboration Agreement). Under the Eisai Collaboration Agreement, Eisai serves as the global operational and regulatory lead for both compounds and all costs, including research, development, sales and marketing expenses, will be shared equally by us and Eisai. Following marketing approval in major markets, such as the U.S., the E.U. and Japan, we will co-promote BAN2401 and E2609 with Eisai and share profits equally. In smaller markets, Eisai will distribute these products and pay us a royalty. The Eisai Collaboration Agreement also provides the parties with certain rights and obligations in the event of a change in control of either party. The Eisai Collaboration Agreement also provides Eisai an option to jointly develop and commercialize BIIB037, our anti- amyloid beta antibody candidate for Alzheimer’s disease (BIIB037 Option) and an option to jointly develop and commercialize one of our anti-tau monoclonal antibodies (Anti-Tau Option). Upon exercise of each of the BIIB037 Option and the Anti-Tau Option, we will execute a separate collaboration agreement with Eisai on terms and conditions that mirror the Eisai Collaboration Agreement. BIIB037 Option Eisai may exercise the BIIB037 Option after either (i) completion of both the current Phase 1b clinical trial for BIIB037 and the current Phase 2 clinical trial for BAN2401 (Post-Phase 2 BIIIB037 Option), or (ii) completion of the Phase 3 clinical trial for BIIB037 (Post-Phase 3 BIIB037 Option) under certain conditions. F- 54 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The consideration we will receive if Eisai exercises the Post-Phase 2 BIIB037 Option depends on the development status of BAN2401. If BAN2401 is then determined to advance to Phase 3, we will be entitled to receive a single payment from Eisai upon regulatory approval of BIIB037 and we will no longer be required to pay Eisai any milestone payments for products containing BAN2401 under the Eisai Collaboration Agreement. If the development of BAN2401 has instead been terminated, we will receive development and commercial milestone payments from Eisai (Post-Phase 2 BIIB037 Milestone Payments). If Eisai does not exercise its Post-Phase 2 BIIB037 Option, we may elect to terminate the Eisai Collaboration Agreement with respect to BAN2401 but, under certain conditions, will have the option to reinstate the Eisai Collaboration Agreement after completion of a BAN2401 Phase 3 clinical trial. If Eisai exercises its Post-Phase 3 BIIB037 Option, Eisai will be required to pay us all Phase 3 development and commercialization costs plus a mark-up and an amount equal to any unpaid Post-Phase 2 BIIB037 Milestone Payments that would have been payable if Eisai had exercised its Post-Phase 2 BIIB037 Option. Anti-Tau Option Eisai may exercise the Anti-Tau Option after completion of the Phase 1 clinical trial of such anti-tau monoclonal antibody. If Eisai exercises its Anti-Tau Option, we will receive an upfront payment from Eisai and will be entitled to additional development and commercial milestone payments. Upon the effective date of the Eisai Collaboration Agreement, we paid Eisai $100.0 million and recorded $17.7 million, reflecting the fair value of the options granted under the Eisai Collaboration Agreement, both of which were classified as research and development expense within our consolidated statements of income. During the second quarter of 2014, Eisai exercised its option under the Eisai Collaboration Agreement to expand the joint development and commercialization activities to include Japan. Upon such exercise, we paid Eisai an additional $35.0 million, and recorded $21.6 million in the second quarter of 2014 as research and development expense within our consolidated statements of income, which represented the difference between the payment made upon exercise of the option and the fair value of that option recorded as research and development expense upon closing of the agreement in the first quarter of 2014. We could pay Eisai up to an additional $1.0 billion under the Eisai Collaboration Agreement based on the future achievement of certain development, regulatory and commercial milestones. A summary of activity related to this collaboration is as follows: (In millions) Total development expense incurred by the collaboration...................... $ Biogen Idec’s share of development expense, excluding upfront and milestone payments, reflected within our consolidated statements of income ..................................................................................................... $ For the Years Ended December 31, 2014 2013 2012 57.5 $ — $ 29.1 $ — $ — — For additional information related to our obligations for the payment of milestones and royalties related to our development and commercialization of BIIB037 and certain anti-tau antibodies, please read about our relationship with Neurimmune in Note 19, Investments in Variable Interest Entities to these consolidated financial statements. Sangamo BioSciences, Inc. On February 22, 2014, we completed an exclusive worldwide research, development and commercialization collaboration and license agreement with Sangamo BioSciences, Inc. (Sangamo) under which both companies will develop and commercialize product candidates for the treatment of two inherited blood disorders, sickle cell disease and beta- thalassemia. The collaboration is currently in the research stage of development. Under the terms of the agreement, we paid Sangamo an upfront payment of $20.0 million in cash, with additional payments of up to approximately $300.0 million based on the achievement of certain development, regulatory and commercial milestones, plus royalties based on sales. We recorded the $20.0 million upfront payment as research and development expense. Under this arrangement, Sangamo will be responsible for identifying a product candidate for the treatment of beta-thalassemia and advancing that candidate through a completed Phase 1 human clinical trial, at which point we would assume responsibility for development. We will jointly develop a sickle cell disease candidate through the potential filing of an investigative new drug application, after which we would assume clinical responsibilities. We will lead the global development and commercialization efforts and Sangamo will have the option to assume co-promotion responsibilities in the U.S. During the year ended December 31, 2014, $28.9 million of expense was reflected within our consolidated statements of income. F- 55 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Other Research and Discovery Arrangements During the year ended December 31, 2014, we entered into several research, discovery and other related arrangements that resulted in $40.0 million recorded as research and development expense within our consolidated statements of income and $3.6 million recorded as prepaid research and development assets within our consolidated balance sheets. During the year ended December 31, 2013, we entered into research, discovery and other arrangements that resulted in $35.0 million recorded as investments and other assets within our consolidated balance sheets and $4.0 million recorded as research and development expense within our consolidated statements of income. These additional arrangements include the potential for future milestone payments based on clinical and commercial development over a period of several years. Samsung Bioepis In February 2012, we entered into a joint venture agreement with Samsung BioLogics Co. Ltd. (Samsung Biologics), establishing an entity, Samsung Bioepis, to develop, manufacture and market biosimilar pharmaceuticals. Samsung Biologics contributed 280.5 billion South Korean won (approximately $250.0 million) for an 85% stake in Samsung Bioepis and we contributed approximately 49.5 billion South Korean won (approximately $45.0 million) for the remaining 15% ownership interest. Our investment is limited to this contribution as we have no obligation to provide any additional funding. As of December 31, 2014, our ownership interest has decreased to approximately 10% as Samsung Bioepis has secured additional equity financing from Samsung Biologics and we have not participated in such financing. We maintain an option to purchase additional stock in Samsung Bioepis that would allow us to increase our ownership percentage up to 49.9%. The exercise of this option is within our control and is based on paying for 49.9% of the total investment made by Samsung Biologics into Samsung Bioepis in excess of what we have already contributed during the agreement plus interest. On December 17, 2013, pursuant to our rights under the joint venture agreement with Samsung Biologics, we entered into an agreement with Samsung Bioepis to commercialize anti-TNF biosimilar product candidates in Europe and in the case of one anti-TNF biosimilar, Japan. Under the terms of this agreement, we paid $36.0 million, which was recorded as a research and development expense within our consolidated statements of income as the programs they relate to had not achieved regulatory approval. Samsung Bioepis is eligible to receive an additional $85.0 million in additional milestones related to clinical development and regulatory approval of the product candidates. Upon commercialization, there will be a 50% profit share with Samsung Bioepis. Samsung Biologics has the power to direct the activities of Samsung Bioepis which will most significantly and directly impact its economic performance. We account for this investment under the equity method of accounting as we maintain the ability to exercise significant influence over Samsung Bioepis through a presence on the entity’s Board of Directors and our contractual relationship. Under the equity method, we record our original investment at cost and subsequently adjust the carrying value of our investments for our share of equity in the entity’s income or losses according to our percentage of ownership. If losses accumulate, we will record our share of losses until our investment has been fully depleted. Once our investment has been fully depleted, we will recognize additional losses only if we provide or are required to provide additional funding. As of December 31, 2014 and 2013, the carrying value of our investment in Samsung Bioepis totaled 9.1 billion and 25.2 billion South Korean won (approximately $8.6 million and $23.9 million), respectively, which is classified as a component of investments and other assets within our consolidated balance sheets. We recognize our share of the results of operations related to our investment in Samsung Bioepis one quarter in arrears when the results of the entity become available, which is reflected as equity in loss of investee, net of tax within our consolidated statements of income. During the years ended December 31, 2014, 2013 and 2012, we recognized a loss on our investment of $15.1 million, $17.2 million and $4.5 million, respectively. F- 56 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Simultaneous with the formation of Samsung Bioepis, we entered into a license agreement, a technical development services agreement and a manufacturing agreement with Samsung Bioepis. Under the terms of the license agreement, we granted Samsung Bioepis an exclusive license to use, develop, manufacture, and commercialize biosimilar products created by Samsung Bioepis using Biogen Idec product-specific technology. In exchange, we will receive single digit royalties on all biosimilar products developed and commercialized by Samsung Bioepis. Under the terms of the technical development services agreement, we provide Samsung Bioepis technical development and technology transfer services, which include, but are not limited to, cell culture development, purification process development, formulation development, and analytical development. Under the terms of our manufacturing agreement, we manufacture clinical and commercial quantities of bulk drug substance of biosimilar products for Samsung Bioepis pursuant to contractual terms. Under limited circumstances, we may also supply Samsung Bioepis with quantities of drug product of biosimilar products for use in clinical trials through arrangements with third party contract manufacturers. For the years ended December 31, 2014, 2013 and 2012, we recognized $58.5 million, $43.1 million and $13.3 million, respectively, in other revenues in relation to these services, which is reflected as a component of other revenues within our consolidated statement of income. 21. Litigation ’755 Patent Litigation On May 28, 2010, Biogen Idec MA Inc. (BIMA) filed a complaint in the U.S. District Court for the District of New Jersey alleging infringement by Bayer Healthcare Pharmaceuticals Inc. (Bayer) (manufacturer, marketer and seller of BETASERON and manufacturer of EXTAVIA), EMD Serono, Inc. (manufacturer, marketer and seller of REBIF), Pfizer, Inc. (co-marketer of REBIF), and Novartis Pharmaceuticals Corp. (marketer and seller of EXTAVIA) of our U.S. Patent No. 7,588,755 (’755 Patent), which claims the use of interferon beta for immunomodulation or treating a viral condition, viral disease, cancers or tumors. The complaint seeks monetary damages, including lost profits and royalties. Bayer had previously filed a complaint against us in the same court, on May 27, 2010, seeking a declaratory judgment that it does not infringe the ’755 Patent and that the patent is invalid, and seeking monetary relief in the form of attorneys' fees, costs and expenses. The court has consolidated the two lawsuits, and we refer to the two actions as the “Consolidated ’755 Patent Actions.” Bayer, Pfizer, Novartis and EMD Serono have all filed counterclaims in the Consolidated ’755 Patent Actions seeking declaratory judgments of patent invalidity and non-infringement, and seeking monetary relief in the form of costs and attorneys' fees, and EMD Serono and Bayer have each filed a counterclaim seeking a declaratory judgment that the ’755 Patent is unenforceable based on alleged inequitable conduct. Bayer has also amended its complaint to seek such a declaration. No trial date has been set. Italian National Medicines Agency In the fourth quarter of 2011, Biogen Idec Italia SRL received notice from the Italian National Medicines Agency (Agenzia Italiana del Farmaco or AIFA) that sales of TYSABRI after mid-February 2009 exceeded a reimbursement limit established pursuant to a Price Determination Resolution (Price Resolution) granted by AIFA in December 2006. On December 23, 2011, we filed an appeal in the Regional Administrative Tribunal of Lazio (Il Tribunale Amministrativo Regionale per il Lazio) in Rome seeking a ruling that the reimbursement limit in the Price Resolution should apply as written to only “the first 24 months” of TYSABRI sales, which ended in mid-February 2009. The appeal is still pending. Earlier this year AIFA approved a resolution affirming that that there is no reimbursement limit from and after February 2013. AIFA and Biogen Idec Italia SRL are discussing a possible resolution for the period from mid-February 2009 through January 2013. Average Manufacturer Price Litigation On September 6, 2011, we and several other pharmaceutical companies were served with a complaint originally filed under seal on October 28, 2008 in the United States District Court for the Eastern District of Pennsylvania by Ronald Streck on behalf of himself and the United States, 24 states and the District of Columbia (collectively the “States”). The complaint alleges that Biogen Idec violated the False Claims Act, 31 U.S.C. § 3729 et seq. and local statutory counterparts by under reporting Average Manufacturer Price (AMP) information to the Centers for Medicare and Medicaid Services. The United States and the States have declined to intervene. We believe we have good and valid defenses. We have not formed an opinion that an unfavorable outcome under the remaining claims is either “probable” or “remote”. Trial is scheduled for the first half of 2016. Government Matters We have learned that state and federal governmental authorities are investigating our sales and promotional practices and have received related subpoenas. We have also received a subpoena from the federal government for documents relating to our relationship with certain pharmacy benefit managers. We are cooperating with the government in these matters. F- 57 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Qui Tam Litigation In August, 2012, we learned that a relator, on behalf of the United States and certain states, filed a suit under seal on February 17, 2011 against us, Elan Corporation, plc, and Elan Pharmaceuticals, Inc. in the United States District Court for the Western District of Virginia. We have neither seen nor been served with the complaint, but understand that it was filed under the Federal False Claims Act. Forward Pharma Litigation On November 18, 2014 Forward Pharma A/S (“Forward Pharma”) filed suit against us in the Regional Court of Dusseldorf, Germany alleging that TECFIDERA infringes German Utility Model DE 20 2005 022 112 U1, which was registered on April 24, 2014, published on June 5, 2014 and expires in October 2015. Forward Pharma seeks a declaration of infringement and a determination of damages. We believe that we have good and valid defenses to the complaint and will vigorously defend against it. We have not formed an opinion that an unfavorable outcome is either “probable” or “remote” and are unable to estimate the magnitude or range of any potential loss. Product Liability and Other Legal Proceedings We are also involved in product liability claims and other legal proceedings generally incidental to our normal business activities. While the outcome of any of these proceedings cannot be accurately predicted, we do not believe the ultimate resolution of any of these existing matters would have a material adverse effect on our business or financial condition. 22. Commitments and Contingencies Leases We rent laboratory and office space and certain equipment under non-cancelable operating leases. These lease agreements contain various clauses for renewal at our option and, in certain cases, escalation clauses typically linked to rates of inflation. Rental expense under these leases, net of amounts recognized in relation to exiting our Weston, Massachusetts facility, which terminate at various dates through 2028, amounted to $62.4 million in 2014. Rent expense was $56.1 million in 2013 and $49.0 million in 2012. In addition to rent, the leases may require us to pay additional amounts for taxes, insurance, maintenance and other operating expenses. As of December 31, 2014, minimum rental commitments under non-cancelable leases, net of income from subleases, for each of the next five years and total thereafter were as follows: (In millions) Minimum lease payments (1)........ $ Less: income from subleases......... Net minimum lease payments $ 2015 2016 2017 2018 2019 67.8 (5.6) 62.2 $ $ 70.8 (6.0) 64.8 $ $ 70.6 (6.0) 64.6 $ $ 61.7 (6.3) 55.4 $ $ 58.9 (6.3) 52.6 Thereafter 411.3 $ (35.2) 376.1 $ $ $ Total 741.1 (65.4) 675.7 (1) As a result of our decision to relocate our corporate headquarters to Cambridge, Massachusetts, we vacated part of our Weston, Massachusetts facility in the fourth quarter of 2013. We incurred a charge of $27.2 million in connection with this move. This charge represented our remaining lease obligation for the vacated portion of our Weston, Massachusetts facility, net of sublease income expected to be received. The term of our sublease to the vacated portion of our Weston, Massachusetts facility started in January 2014 and will continue through the remaining term of our lease agreement. Under certain of our lease agreements, we are contractually obligated to return leased space to its original condition upon termination of the lease agreement. At the inception of a lease with such conditions, we record an asset retirement obligation liability and a corresponding capital asset in an amount equal to the estimated fair value of the obligation. In subsequent periods, for each such lease, we record interest expense to accrete the asset retirement obligation liability to full value and depreciate each capitalized asset retirement obligation asset, both over the term of the associated lease agreement. Our asset retirement obligations were not significant as of December 31, 2014 or 2013. Tax Related Obligations We exclude liabilities pertaining to uncertain tax positions from our summary of contractual obligations as we cannot make a reliable estimate of the period of cash settlement with the respective taxing authorities. As of December 31, 2014, we have approximately $80.2 million of net liabilities associated with uncertain tax positions. F- 58 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Other Funding Commitments As of December 31, 2014, we have several on-going clinical studies in various clinical trial stages. Our most significant clinical trial expenditures are to CROs. The contracts with CROs are generally cancellable, with notice, at our option. We have recorded accrued expenses of approximately $41.6 million on our consolidated balance sheet for expenditures incurred by CROs as of December 31, 2014. We have approximately $472.3 million in cancellable future commitments based on existing CRO contracts as of December 31, 2014. Contingent Development, Regulatory and Commercial Milestone Payments Based on our development plans as of December 31, 2014, we have committed to make potential future milestone payments to third parties of up to approximately $2.8 billion as part of our various collaborations, including licensing and development programs. Payments under these agreements generally become due and payable only upon achievement of certain development, regulatory or commercial milestones. Because the achievement of these milestones had not occurred as of December 31, 2014, such contingencies have not been recorded in our financial statements. Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful achievement of certain development, regulatory approval and commercial milestones. TYSABRI Contingent Payments On April 2, 2013, we acquired full ownership of all remaining rights to TYSABRI from Elan that we did not already own or control. Under the terms of the acquisition agreement, we are obligated to make contingent payments to Elan of 18% on annual worldwide net sales up to $2.0 billion and 25% on annual worldwide net sales that exceed $2.0 billion. Royalty payments to Elan and other third parties are recognized as cost of sales within our consolidated statements of income. Contingent Consideration related to Business Combinations In connection with our purchase of the noncontrolling interests in our joint venture investments in Biogen Dompé SRL and Biogen Dompé Switzerland GmbH and our acquisitions of Stromedix, Biogen Idec International Neuroscience GmbH (BIN) and Biogen Idec Hemophilia Inc. (BIH), we may pay up to approximately $850 million in remaining milestones based upon the achievement of certain events. These milestones may not be achieved. As the acquisitions of the noncontrolling interests in our joint venture investments and our acquisitions of Stromedix and BIN, formerly Panima Pharmaceuticals AG, occurred after January 1, 2009, we record contingent consideration liabilities at their fair value on the acquisition date and revalue these obligations each reporting period. For additional information related to our acquisition of Stromedix please read Note 2, Acquisitions, to our consolidated financial statements included in this report. BIH In connection with our acquisition of BIH, formerly Syntonix, in January 2007, we agreed to pay up to an additional $80.0 million if certain milestone events associated with the development of BIH’s lead product, ALPROLIX are achieved. The first $40.0 million contingent payment was achieved in the first quarter of 2010. We paid an additional $20.0 million during the second quarter of 2014 as ALPROLIX was approved for the treatment of hemophilia B. A second $20.0 million contingent payment will occur if prior to the tenth anniversary of the closing date, a marketing authorization is granted by the EMA for ALPROLIX. Fumapharm AG In 2006, we acquired Fumapharm AG. As part of this acquisition we acquired FUMADERM and TECFIDERA (together, Fumapharm Products). We paid $220.0 million upon closing of the transaction and agreed to pay an additional $15.0 million if a Fumapharm Product was approved for MS in the U.S. or E.U. In the second quarter of 2013, we paid this $15.0 million contingent payment as TECFIDERA was approved in the U.S. for MS by the FDA. We are also required to make additional contingent payments to former shareholders of Fumapharm AG or holders of their rights based on the attainment of certain cumulative sales levels of Fumapharm Products and the level of total net sales of Fumapharm Products in the prior twelve month period, as defined in the acquisition agreement. During 2014, we paid a $25.0 million contingent payment as we reached the $1.0 billion cumulative sales level related to the Fumapharm Products in 2013, a $150.0 million contingent payment as we reached the $2.0 billion cumulative sales level related to Fumapharm Products in the second quarter of 2014, a $200.0 million contingent payment as we reached the $3.0 billion cumulative sales level in the third quarter of 2014 and accrued $250.0 million upon reaching $4.0 billion in total cumulative sales of Fumapharm Products, in the fourth quarter of 2014. F- 59 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) We will owe an additional $300.0 million contingent payment for every additional $1.0 billion in cumulative sales level of Fumapharm Products reached if the prior 12 months sales of the Fumapharm Products exceed $3.0 billion, until such time as the cumulative sales level reaches $20.0 billion, at which time no further contingent payment shall be due. These payments will be accounted for as an increase to goodwill as incurred, in accordance with the accounting standard applicable to business combinations when we acquired Fumapharm. Any portion of the payment which is tax deductible will be recorded as a reduction to goodwill. Payments are due within 60 days following the end of the quarter in which the applicable cumulative sales level has been reached. 23. Guarantees As of December 31, 2014 and 2013, we did not have significant liabilities recorded for guarantees. We enter into indemnification provisions under our agreements with other companies in the ordinary course of business, typically with business partners, contractors, clinical sites and customers. Under these provisions, we generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of our activities. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential amount of future payments we could be required to make under these indemnification provisions is unlimited. However, to date we have not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the estimated fair value of these agreements is minimal. Accordingly, we have no liabilities recorded for these agreements as of December 31, 2014 and 2013. 24. Employee Benefit Plans We sponsor various retirement and pension plans. Our estimates of liabilities and expenses for these plans incorporate a number of assumptions, including expected rates of return on plan assets and interest rates used to discount future benefits. 401(k) Savings Plan We maintain a 401(k) Savings Plan which is available to substantially all regular employees in the U.S. over the age of 21. Participants may make voluntary contributions. We make matching contributions according to the 401(k) Savings Plan’s matching formula. All matching contributions and participant contributions vest immediately. The 401(k) Savings Plan also holds certain transition contributions on behalf of participants who previously participated in the Biogen, Inc. Retirement Plan. The expense related to our 401(k) Savings Plan primarily consists of our matching contributions. Expense related to our 401(k) Savings Plan totaled $49.3 million, $39.3 million and $32.8 million for the years ended December 31, 2014, 2013 and 2012, respectively. Deferred Compensation Plan We maintain a non-qualified deferred compensation plan, known as the Supplemental Savings Plan (SSP), which allows a select group of management employees in the U.S. to defer a portion of their compensation. The SSP also provides certain credits to highly compensated U.S. employees, which are paid by the company. These credits are known as the Restoration Match. The deferred compensation amounts are accrued when earned. Such deferred compensation is distributable in cash in accordance with the rules of the SSP. Deferred compensation amounts under such plan as of December 31, 2014 and 2013 totaled approximately $105.2 million and $84.7 million, respectively, and are included in other long-term liabilities within the accompanying consolidated balance sheets. The SSP also holds certain transition contributions on behalf of participants who previously participated in the Biogen, Inc. Retirement Plan. The Restoration Match and participant contributions vest immediately. Distributions to participants can be either in one lump sum payment or annual installments as elected by the participants. F- 60 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) Pension Plans Our retiree benefit plans include defined benefit plans for employees in our affiliates in Switzerland and Germany as well as other insignificant defined benefit plans in certain other countries in which we maintain an operating presence. Our Swiss plan is a government-mandated retirement fund that provides employees with a minimum investment return. The minimum investment return is determined annually by Swiss government and was 1.75% in 2014 and 1.5% in 2013 and 2012, respectively. Under this plan, both we and certain of our employees with annual earnings in excess of government determined amounts are required to make contributions into a fund managed by an independent investment fiduciary. Employer contributions must be in an amount at least equal to the employee’s contribution. Minimum employee contributions are based on the respective employee’s age, salary, and gender. As of December 31, 2014 and 2013, the Plan had an unfunded net pension obligation of approximately $31.9 million and $22.6 million, respectively, and plan assets which totaled approximately $43.9 million and $38.1 million, respectively. In 2014, 2013 and 2012, we recognized expense totaling $9.8 million, $10.9 million and $3.8 million, respectively, related to our Swiss plan. The obligations under the German plan are unfunded and totaled $24.8 million and $20.0 million as of December 31, 2014 and 2013, respectively. Net periodic pension cost related to the German plan totaled $3.5 million, $3.3 million and $1.9 million for the years ended December 31, 2014, 2013 and 2012, respectively. 25. Segment Information We operate as one operating segment, which is focused on discovering, developing, manufacturing and delivering therapies for neurological, autoimmune and hematologic disorders, and, therefore, our chief operating decision-maker manages the operations of our company as a single operating segment. Enterprise-wide disclosures about product revenues, other revenues and long-lived assets by geographic area and information relating to major customers are presented below. Revenues are primarily attributed to individual countries based on location of the customer or licensee.

F- 63 BIOGEN IDEC INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 27. Subsequent Events Convergence Pharmaceuticals On January 11, 2015, we announced that we plan to acquire Convergence Pharmaceuticals (Convergence), a clinical- stage biopharmaceutical company with a focus on developing ion channel-modulating product candidates for neuropathic pain. The acquisition will be centered on the development of Convergence’s Phase 2 clinical candidate (CNV1014802), which has demonstrated clinical activity in proof of concept studies for trigeminal neuralgia (TGN), a chronic orphan disease consisting of debilitating, episodic facial pain. Additionally, CNV1014802 has demonstrated proof of concept for treating pain associated with lumbosacral radiculopathy, more commonly known as sciatica, and has potential applicability in several other neuropathic pain states. Under the terms of the transaction, we will pay Convergence shareholders an upfront payment of $200.0 million. Convergence shareholders are eligible to receive additional payments up to $475.0 million contingent on future milestones. Completion of the transaction is subject to customary closing conditions, including antitrust clearance in the U.S. under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. F- 64 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Board of Directors and Shareholders of Biogen Idec Inc. In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, comprehensive income, equity and cash flows present fairly, in all material respects, the financial position of Biogen Idec Inc. and its subsidiaries at December 31, 2014 and December 31, 2013, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2014 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ PricewaterhouseCoopers LLP Boston, Massachusetts February 4, 2015 F- 65 Exhibit No. 2.1† 3.1 3.2 4.1 4.2 4.3 10.1 10.2† 10.3 10.4† 10.5† 10.6* 10.7* 10.8* 10.9* 10.10* 10.11* 10.12* 10.13* 10.14* 10.15* 10.16* EXHIBIT INDEX Description Asset Purchase Agreement among Biogen Idec International Holding Ltd., Elan Pharma International Limited and Elan Pharmaceuticals, Inc., dated as of February 5, 2013.
