The Company and Summary of Significant Accounting Policies | The Company and Summary of Significant Accounting Policies Jazz Pharmaceuticals plc is an international biopharmaceutical company focused on improving patients’ lives by identifying, developing and commercializing meaningful products that address unmet medical needs. We have a diverse portfolio of products and product candidates, with a focus in the areas of sleep and hematology/oncology. Our lead marketed products are: • Xyrem ® (sodium oxybate) oral solution , the only product approved by the U.S. Food and Drug Administration, or FDA, and marketed in the U.S. for the treatment of both cataplexy and excessive daytime sleepiness, or EDS, in patients with narcolepsy; • Erwinaze ® (asparaginase Erwinia chrysanthemi ) , a treatment approved in the U.S. and in certain markets in Europe (where it is marketed as Erwinase ® ) for patients with acute lymphoblastic leukemia, or ALL, who have developed hypersensitivity to E. coli -derived asparaginase; • Defitelio ® (defibrotide sodium) , a product approved in the U.S. for the treatment of adult and pediatric patients with hepatic veno-occlusive disease, or VOD, also known as sinusoidal obstruction syndrome, or SOS, with renal or pulmonary dysfunction following hematopoietic stem cell transplantation, or HSCT, and in Europe (where it is marketed as Defitelio ® (defibrotide)) for the treatment of severe VOD in adults and children undergoing HSCT therapy; and • Vyxeos TM (daunorubicin and cytarabine) liposome for injection , a product approved in the U.S. for the treatment of adults with newly-diagnosed therapy-related acute myeloid leukemia, or AML, or AML with myelodysplasia-related changes. Our strategy is to create shareholder value by: • Growing sales of the existing products in our portfolio, including by identifying and investing in growth opportunities such as new treatment indications and new geographic markets; • Acquiring or licensing rights to clinically meaningful and differentiated products that are on the market or product candidates that are in late-stage development; and • Pursuing targeted development of post-discovery differentiated product candidates. We apply a disciplined approach to allocating our resources between investments in our current commercial and development portfolio and acquisitions or in-licensing of new assets.

Basis of Presentation These unaudited condensed consolidated financial statements have been prepared following the requirements of the U.S. Securities and Exchange Commission, or SEC, for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by U.S. generally accepted accounting principles, or U.S. GAAP, can be condensed or omitted. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our annual consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2016 . In the opinion of management, these condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, considered necessary for the fair presentation of our financial position and operating results. The results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 , for any other interim period or for any future period. These condensed consolidated financial statements include the accounts of Jazz Pharmaceuticals plc and our subsidiaries, and intercompany transactions and balances have been eliminated. Significant Risks and Uncertainties Our financial results remain significantly influenced by sales of Xyrem. In the three and nine months ended September 30, 2017, net product sales of Xyrem were $303.9 million and $874.2 million , respectively, which represented 74% and 75% of total net product sales, respectively. Our ability to maintain or increase product sales of Xyrem is subject to risks and uncertainties, including the potential U.S. introduction of a generic version of Xyrem before the entry dates specified in our settlements with certain companies that had filed abbreviated new drug applications, or ANDAs, with the FDA seeking approval to market a generic version of Xyrem or on terms that are different from those contemplated by the settlements; the potential U.S. introduction of an alternative product to Xyrem for treating cataplexy and/or EDS in narcolepsy; changes to, increases in or uncertainties around regulatory restrictions, including, among other things, changes to our Xyrem risk evaluation and mitigation strategy, or REMS, particularly in light of the FDA’s waiver of the single shared REMS requirement for sodium oxybate and approval of a separate generic sodium oxybate REMS; any increase in pricing pressure from, or restrictions on reimbursement imposed by, third party payors; changes in healthcare laws and policy, including changes in requirements for patient assistance programs, rebates, reimbursement and coverage by federal healthcare programs, and changes resulting from increased scrutiny on pharmaceutical pricing and REMS programs by government entities; operational disruptions at the Xyrem central pharmacy or any failure to comply with our REMS obligations to the satisfaction of the FDA; any supply or manufacturing problems, including any problems with our sole source provider of the active pharmaceutical ingredient for Xyrem; continued acceptance of Xyrem by physicians and patients, even in the face of negative publicity that surfaces from time to time; changes to our label, including new safety warnings or changes to our boxed warning, that further restrict how we market and sell Xyrem; and our U.S.-based sodium oxybate and Xyrem suppliers’ ability to obtain sufficient quotas from the U.S. Drug Enforcement Administration, or DEA, to satisfy our needs for Xyrem. Although Xyrem is protected by patents covering its manufacture, formulation, distribution system and method of use, eight companies have filed ANDAs with the FDA seeking approval to market a generic version of Xyrem. We filed patent lawsuits against each of the ANDA filers in the U.S. District Court for the District of New Jersey, or the District Court, and an additional lawsuit against the most recent ANDA filer, Ascent Pharmaceuticals, Inc., or Ascent, in the U.S. District Court for the Eastern District of New York, or EDNY, where Ascent is incorporated. On April 5, 2017, we settled all lawsuits against the first ANDA filer, West-Ward Pharmaceuticals Corp. (a wholly owned subsidiary of Hikma Pharmaceuticals PLC), which acquired Roxane Laboratories, Inc., or West-Ward, granting West-Ward the right to sell an authorized generic version of Xyrem, or the West-Ward AG Product, commencing on January 1, 2023, or earlier under certain circumstances, and granting West-Ward a license to launch its generic sodium oxybate product as early as six months thereafter. In the second quarter of 2016, we had settled lawsuits with two of the other ANDA filers, granting those filers a license to manufacture, market and sell their generic versions of Xyrem on or after December 31, 2025, or earlier depending on the occurrence of certain events. In addition, on August 22, 2017, we settled all lawsuits with Ascent, granting Ascent a license to manufacture, market and sell its generic version of Xyrem on or after December 31, 2025, or earlier depending on the occurrence of certain events. For a description of our settlements with West-Ward and three of the other ANDA filers, see “Overview—Challenges, Risks and Trends Related to Our Lead Marketed Products” in Part I, Item 2 of this Quarterly Report on Form 10-Q. Lawsuits with the remaining non-settling ANDA filers have been consolidated as one case and remain pending in the District Court. Although no trial date has been set, discovery is scheduled to conclude in the second quarter of 2018, and the trial in this consolidated case could occur as early as mid-2018. For a description of these legal proceedings, see “Legal Proceedings” in Part II, Item 1 of this Quarterly Report on Form 10-Q. We cannot predict the timing or outcome of the ANDA litigation proceedings against the remaining non-settling ANDA filers. In July 2016, the Patent Trial and Appeal Board, or PTAB, of the U.S. Patent and Trademark Office issued final decisions that the claims of six patents listed in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” or Orange Book, as covering the Xyrem REMS are unpatentable. We filed a notice of appeal of these decisions on February 22, 2017. If the United States Court of Appeals for the Federal Circuit upholds those decisions on appeal, these claims will be canceled, and we will not be able to enforce these patents. In March 2016, the PTAB partially instituted an inter partes review, or IPR, on three claims of a seventh REMS patent, declining to review 25 of 28 claims. The PTAB issued a final decision in March 2017 that the three claims they reviewed are unpatentable. We filed a notice of appeal of that decision on May 18, 2017, and the Court of Appeals for the Federal Circuit has consolidated the appeal of the March 2017 decision with the pending appeals of the July 2016 decisions. For a description of these legal proceedings, see “Legal Proceedings” in Part II, Item 1 of this Quarterly Report on Form 10-Q. We cannot predict whether additional post-grant patent review challenges will be filed by any of the ANDA filers or any other entity, the outcome of any proceeding, including any appeal, or the impact any IPR or other proceeding might have on ongoing ANDA litigation proceedings or other aspects of our Xyrem business. On January 17, 2017, the FDA announced approval of the West-Ward ANDA, and on January 19, 2017, the FDA tentatively approved two additional ANDAs for generic versions of Xyrem, one for Amneal Pharmaceuticals, LLC, or Amneal, and one for Ohm Laboratories Inc., formerly known as Ranbaxy, Inc., or Ohm. West-Ward’s ANDA approval includes a waiver that permits West-Ward to use a separate REMS program from the Xyrem REMS, or the generic sodium oxybate REMS, on the condition that the generic sodium oxybate REMS be open to all future sponsors of ANDAs or new drug applications, or NDAs, for sodium oxybate products. We were not involved in the development of the generic sodium oxybate REMS. We continue to evaluate potential challenges based on the FDA’s waiver of the requirement for a single, shared system REMS in connection with the approvals of the ANDAs, including whether the FDA’s waiver decision meets the conditions for such a waiver under applicable law. We cannot predict whether or when we may pursue any such challenges or whether any such challenges would be successful. The actual timing of any commercial launch of an authorized generic or generic version of Xyrem is uncertain. We do not believe a launch by an ANDA filer is likely to occur prior to either a date agreed in a settlement agreement between us and such ANDA filer or a decision by the District Court, or an appellate court, if applicable, in our ongoing patent litigation. However, notwithstanding our patents, and settlement agreements licensing those patents as of future dates, it is possible that West-Ward, Amneal, Ohm or any other company that receives FDA approval of an ANDA for a generic version of Xyrem or an NDA for another sodium oxybate product could introduce a generic version of Xyrem or other sodium oxybate product before the entry dates specified in our settlement agreements or before our patents expire, including if it is determined that the introduction of the competing product does not infringe our patents, if it is determined that our patents are invalid or unenforceable, or if a non-settling ANDA filer that has received approval for its product decides, before applicable ongoing patent litigation is concluded, to launch a sodium oxybate product at risk of being held liable for damages for patent infringement. In addition, even if we prevail in our ongoing litigation at trial or on appeal, we cannot guarantee that the court will grant an injunction that prevents the ANDA filers from marketing their generic versions of Xyrem. Instead the court may order an ANDA filer that is found to infringe to pay damages in the form of lost profits or a reasonable royalty, which could be significant. We expect that the launch of any generic version of Xyrem, including the West-Ward AG Product or other authorized generic version of Xyrem, or the approval and launch of other products that compete with Xyrem, could have a material adverse effect on our sales of Xyrem and on our business, financial condition, results of operations and growth prospects. For further discussion regarding the risks associated with the West-Ward settlement agreement, the tentative approval of the Amneal and Ohm ANDAs, potential approval or tentative approval of additional ANDAs, the potential launch of a generic version of Xyrem, or the approval and launch of other sodium oxybate or other products that compete with Xyrem, see the risk factors under the headings “Risks Related to Xyrem and the Significant Impact of Xyrem Sales,” “ We face substantial competition from other companies, including companies with greater resources, including larger sales organizations and more experience working with large and diverse product portfolios, than we have ,” and “Risks Related to Our Intellectual Property” in Part II, Item 1A of this Quarterly Report on Form 10-Q. In August 2015, we implemented the current Xyrem REMS, and we have submitted and expect to continue to submit ongoing assessments as set forth in the FDA’s Xyrem REMS approval letter. However, we cannot guarantee that our implementation and ongoing assessments will be satisfactory to the FDA or that the Xyrem REMS will satisfy the FDA’s expectations in its evaluation of the Xyrem REMS on an ongoing basis. Any failure to comply with the REMS obligations could result in enforcement action by the FDA; lead to changes in our Xyrem REMS obligations; negatively affect sales of Xyrem; result in additional costs and expenses for us; and/or take a significant amount of time, any of which could materially and adversely affect our business, financial condition, results of operations and growth prospects. Further, we cannot predict whether the FDA will request, seek to require or ultimately require modifications to, or impose additional requirements on, the Xyrem REMS in connection with the anticipated distribution of the West-Ward AG Product, the approval of the generic sodium oxybate REMS or otherwise, or the potential timing, terms or propriety thereof. Any such modifications or additional requirements could make it more difficult or expensive for us to distribute Xyrem, make distribution easier for sodium oxybate competitors, impair the safety profile of Xyrem and/or negatively affect sales of Xyrem. We may face pressure to modify the Xyrem REMS, or license or share intellectual property pertinent to the Xyrem REMS, including proprietary data required for the safe distribution of sodium oxybate, in connection with the FDA’s approval of the generic sodium oxybate REMS. We cannot predict the outcome or impact on our business of any future action that we may take with respect to the approval of the generic sodium oxybate REMS, or licensing or sharing intellectual property pertinent to the Xyrem REMS or elements of the Xyrem REMS. For more information, see the risk factors under the headings “ The launch of a generic version of Xyrem or other sodium oxybate products that compete with Xyrem would adversely affect sales of Xyrem ” and “ We have incurred and expect to continue to incur substantial costs as a result of litigation or other proceedings relating to patents, other intellectual property rights and related matters, and we may be unable to protect our rights to, or commercialize, our products ” in Part II, Item 1A of this Quarterly Report on Form 10-Q. In September 2016, Jazz Pharmaceuticals, Inc., our wholly owned subsidiary, submitted a Citizen Petition to the FDA requesting that, for safety reasons, the FDA refuse to approve any sodium oxybate ANDA with a proposed package insert or REMS that omits the portions of the Xyrem package insert and the Xyrem REMS that instruct prescribers on adjusting the dose of the product when it is co-administered with divalproex sodium (also known as valproate or valproic acid). On January 17, 2017, the FDA granted the Citizen Petition with respect to the Xyrem package insert. The FDA concluded that it will not approve any sodium oxybate ANDA referencing Xyrem that does not include in its package insert the portions of the currently approved Xyrem package insert related to the drug-drug interaction, or DDI, with divalproex sodium. The FDA stated that it did not need to reach the question of whether the DDI information could have been excluded from the generic sodium oxybate REMS materials because it was approving a REMS in connection with a sodium oxybate ANDA including that information. Our Xyrem patents include three method of administration patents relating to a DDI, or DDI patents, covering these instructions on the Xyrem package insert and Xyrem REMS. We cannot predict whether or when one or more of the ANDA filers may pursue a challenge to the FDA’s response to the Citizen Petition or whether any such challenges would be successful. Likewise, we cannot predict whether we will be able to maintain the validity of, or will otherwise obtain a judicial determination that the generic sodium oxybate package insert or the generic sodium oxybate REMS will infringe, any of our patents or, if we prevail in proving infringement, whether a court will grant an injunction that prevents any non-settling ANDA filer or other company introducing a different sodium oxybate product from marketing its product. For a further discussion of risks and uncertainties related to our REMS, our REMS patents and our DDI patents, see the risk factors under the headings “Risks Related to Xyrem and the Significant Impact of Xyrem Sales” and “Risks Related to Our Intellectual Property” in Part II, Item 1A of this Quarterly Report on Form 10-Q. We may also face competition from companies with other sodium oxybate products. For example, we are aware of a third party that has stated that it intends to file an NDA to market a once nightly formulation of sodium oxybate for treatment of cataplexy and/or EDS in narcolepsy under Section 505(b)(2) of the Federal Food, Drug and Cosmetic Act, which allows companies to seek approval of a product that is similar, but not identical, to a previously-approved brand-name product. We are also aware of a product to treat adult patients with narcolepsy with or without cataplexy that received marketing approval in Europe in 2016. While this product is currently not approved by the FDA for marketing in the U.S., the company that has exclusive U.S. commercialization rights to this product recently announced that it expects to establish an expanded access program for the product in early 2018 and submit an NDA to the FDA for the treatment of narcolepsy in adult patients during the first half of 2018. See the risk factor under the heading “ We face substantial competition from other companies, including companies with greater resources, including larger sales organizations and more experience working with large and diverse product portfolios, than we have ” in Part II, Item 1A of this Quarterly Report on Form 10-Q. Obtaining and maintaining appropriate reimbursement for Xyrem in the U.S. is increasingly challenging due to, among other things, the attention being paid to healthcare cost containment and prescription drug pricing, pricing pressure from third party payors and increasingly restrictive reimbursement conditions being imposed by third party payors. In this regard, we have experienced and expect to continue to experience increasing pressure from third party payors to agree to discounts, rebates or other pricing terms for Xyrem. Any such restrictive pricing terms or additional reimbursement conditions could have a material adverse effect on our Xyrem revenues. In addition, drug pricing by pharmaceutical companies has recently come under close scrutiny, particularly with respect to companies that have increased the price of products after acquiring those products from other companies. We expect that healthcare policies and reforms intended to curb healthcare costs will continue to be proposed, which could limit the prices that we charge for our products, including Xyrem, limit our commercial opportunity and/or negatively impact revenues from sales of our products. Also, price increases on Xyrem and our other products, and negative publicity regarding pricing and price increases generally, whether with respect to our products or products distributed by other pharmaceutical companies, could negatively affect market acceptance of Xyrem and our other products. In the three and nine months ended September 30, 2017 , net product sales of our second largest product, Erwinaze/Erwinase (which we refer to in this report as Erwinaze unless otherwise indicated or the context otherwise requires), were $49.2 million and $149.6 million , respectively, which represented 12% and 13% of total net product sales, respectively. We seek to increase sales of Erwinaze, as well as to make Erwinaze more widely available, through ongoing sales and marketing activities. Erwinaze is licensed from and manufactured by a single source, Porton Biopharma Limited, or PBL, which is wholly owned by the U.K. Secretary of State for Health. Our agreement with PBL, including our license, expires in December 2020, subject to five -year extensions unless terminated by either party in writing by December 2018. We cannot predict whether the term of the agreement will be extended or, if extended, the terms of any such extension. Erwinaze was approved by the FDA under a biologics license application, or BLA, and was launched in the U.S. in November 2011. The FDA’s approval of the BLA for Erwinaze includes a number of post-marketing commitments related to the manufacture of Erwinaze by PBL. We cannot predict if or when PBL will comply with its manufacturing-related post-marketing commitments that are part of the BLA approval. In January 2017, the FDA issued a warning letter to PBL indicating that it was not satisfied with PBL’s response to the FDA Form 483 issued to PBL in March 2016, citing significant violations of current Good Manufacturing Practices, or cGMP, for finished pharmaceuticals and significant deviations from cGMP for active pharmaceutical ingredients, or APIs. In March 2017, PBL filed a response to the warning letter with the FDA. We attended a meeting with PBL and the FDA in the third quarter of 2017 to discuss the warning letter, and PBL continues to address the issues identified by the FDA in the warning letter. We cannot predict if or when PBL will correct the violations and deviations to the satisfaction of the FDA or whether the FDA will be satisfied with PBL’s response to the warning letter. Any failure to do so could result in the FDA refusing admission of Erwinaze into the U.S., as well as additional enforcement actions by the FDA and other regulatory entities. In addition, a significant challenge to our ability to maintain current sales levels and to increase sales is our need to avoid supply disruptions of Erwinaze due to capacity constraints, production delays, quality or regulatory challenges or other manufacturing difficulties. The current manufacturing capacity for Erwinaze is completely absorbed by demand for the product. We are working with PBL to evaluate potential expansion of its production capacity to increase the supply of Erwinaze over the longer term and to address the production delays and quality challenges, and related regulatory scrutiny. As a consequence of constrained manufacturing capacity, we have had an extremely limited or no ability to build product inventory levels that can be used to absorb disruptions to supply resulting from quality, regulatory or other issues. We have experienced product quality, manufacturing and inventory challenges that have resulted, and may continue to result from time to time through the remainder of 2017 and into 2018, in disruptions in our ability to supply certain markets and have caused, and may in the future cause, us to implement batch-specific, modified product use instructions. Most recently, we experienced supply disruptions in the third quarter of 2017 in the U.S. and certain other countries. As capacity constraints and supply disruptions continue, whether as a result of continued quality or other manufacturing issues, regulatory issues or otherwise, we will be unable to build a desired excess level of product inventory, our ability to supply the market may continue to be compromised and physicians’ decisions to use Erwinaze have been, and in the future may continue to be, negatively impacted. Additional Erwinaze supply disruptions and/or our inability to expand production capacity could materially adversely affect our sales of and revenues from Erwinaze and our potential future maintenance and growth of the market for this product. Our ability to successfully and sustainably grow sales of Erwinaze is subject to a number of other risks and uncertainties, including the limited population of patients with ALL and the incidence of hypersensitivity reactions to E. coli -derived asparaginase within that population, our need to apply for and receive marketing authorizations, through the European Union’s, or EU’s, mutual recognition procedure or otherwise, in certain additional countries if we decide to launch promotional efforts in those countries, as well as those other risks and uncertainties discussed in “Risk Factors” in Part II, Item 1A of this Quarterly Report on Form 10-Q. In the three and nine months ended September 30, 2017 , net product sales of Defitelio/defibrotide represented 8% of total net product sales for both periods. We acquired this product in January 2014 in connection with our acquisition of Gentium S.r.l., or Gentium, which we refer to as the Gentium Acquisition, and secured worldwide rights to the product by acquiring rights to defibrotide in the Americas in August 2014. We began to commercialize Defitelio in certain European countries in 2014. The process of maintaining pricing and reimbursement approvals is complex and varies from country to country. Many European countries periodically review their reimbursement classes, which could have an adverse impact on the reimbursement status of Defitelio. We cannot predict the outcome of periodic pricing and reimbursement reviews across Europe. If we are unable to maintain favorable pricing and reimbursement approvals in countries that represent significant markets, especially where a country’s reimbursed price influences other countries, our anticipated revenue from and growth prospects for Defitelio in the EU could be negatively affected. In March 2016, the FDA approved our NDA for Defitelio for the treatment of adult and pediatric patients with VOD with renal or pulmonary dysfunction following HSCT. We launched Defitelio in the U.S. shortly after FDA approval, and our U.S. commercial launch is still at an early stage. Our ability to realize the anticipated benefits from our investment in Defitelio is subject to risks and uncertainties, including the continued acceptance of Defitelio in the U.S. by hospital pharmacy and therapeutics committees and the continued availability of adequate coverage and reimbursement by government programs and third party payors; the limited experience of U.S. physicians in diagnosing and treating VOD, particularly in adults, and the possibility that physicians may not initiate or may delay initiation of treatment while waiting for VOD symptoms to improve, or terminate treatment before the end of the recommended dosing schedule; our ability to successfully maintain or grow sales of Defitelio in Europe and other non-U.S. countries; delays or problems in the supply or manufacture of the product; the limited size of the population of VOD patients who are indicated for treatment with Defitelio (particularly if changes in HSCT treatment protocols reduce the incidence of VOD diagnosis); our ability to meet the post-marketing commitments and requirements imposed by the FDA in connection with its approval of our NDA for Defitelio; and our ability to obtain marketing approval in other countries and to develop the product for additional indications, as well as those other risks and uncertainties discussed in “Risk Factors” in Part II, Item 1A of this Quarterly Report on Form 10-Q. If sales of Defitelio do not reach the levels we expect, our anticipated revenue from the product will be negatively affected, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects. In addition, we made a significant investment in Vyxeos through the acquisition of Celator Pharmaceuticals Inc., or Celator, in July 2016, or the Celator Acquisition. On August 3, 2017, the FDA approved our NDA for Vyxeos for the treatment of adults with newly-diagnosed therapy-related AML or AML with myelodysplasia-related changes. We launched and began shipping Vyxeos in the U.S. in August 2017, and the launch is at an early stage. We submitted a marketing authorization application for Vyxeos to the European Medicines Agency in the fourth quarter of 2017. Our ability to realize the anticipated benefits from our investment in Vyxeos is subject to additional risks and uncertainties, including our ability to differentiate Vyxeos from other liposomal chemotherapies and generically available chemotherapy combinations with which physicians and treatment centers are more familiar; delays or problems in the supply or manufacture of the product, including the ability of the third parties upon which we rely to manufacture Vyxeos and its APIs to manufacture sufficient quantities in accordance with applicable specifications; the need to establish pricing and reimbursement support for Vyxeos in the U.S. and in other countries; the acceptance of Vyxeos in the U.S. and other countries by hospital pharmacy and therapeutics committees and the availability of adequate coverage and reimbursement by government programs and third party payors; the approval and use of new and novel compounds in AML that are only approved for use in combination with other agents and that have not been tested in combination with Vyxeos; and the limited size of the population of high-risk AML patients who may potentially be indicated for treatment with Vyxeos, particularly given the ongoing clinical trials by other companies with the same patient population, as well as those other risks and uncertainties discussed in “Risk Factors” in Part II, Item 1A of this Quarterly Report on Form 10‑Q. If sales of Vyxeos do not reach the levels we expect, or we are unable to obtain regulatory approval for Vyxeos in Europe in a timely manner, or at all, our anticipated revenue from Vyxeos would be negatively affected, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects. In May and October 2016 and in February 2017, we received subpoenas from the U.S. Attorney’s Office for the District of Massachusetts requesting documents related to our support of 501(c)(3) organizations that provide financial assistance to Medicare patients and documents concerning the provision of financial assistance to Medicare patients taking drugs sold by us. We are cooperating with the investigation, and the outcome of this investigation could include an enforcement action or a settlement with the federal government. The Office of the Inspector General has established guidelines that permit pharmaceutical manufacturers to make donations to charitable organizations who provide co-pay assistance to Medicare patie |
