Summary of Significant Accounting Policies

Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a branded specialty pharmaceutical company. Our primary focus is on the development and potential U.S. Food and Drug Administration (“FDA”) approval for FT218 which is in a Phase 3 clinical trial for the treatment of narcolepsy patients suffering from excessive daytime sleepiness (EDS) and cataplexy. In addition, we market three sterile injectable drugs used in the hospital setting which were developed under our “unapproved marketed drug” (UMD) program. The Company is headquartered in Dublin, Ireland with operations in St. Louis, Missouri and Lyon, France. For more information, please visit www.avadel.com.

Avadel is developing FT218, an investigational once-nightly formulation of sodium oxybate based on its propriety Micropump® drug delivery technology, for the treatment of EDS and cataplexy in patients suffering from narcolepsy. FT218 is currently being evaluated in a Phase 3 clinical trial called REST-ON. In addition, the Company submitted a new drug application (“NDA”) in March 2019 on a fourth sterile injectable drug used in the hospital setting (“UMD #4”), which, if approved, could contribute revenues to Avadel starting in 2020. In May 2019, the FDA accepted this NDA, AV001, with a Prescription Drug User Fee Act (PDUFA) target action date of December 15, 2019.

Our current marketed products include:


•	Akovaz® (ephedrine sulfate injection, USP), an alpha- and beta-adrenergic agonist and a norepinephrine-releasing agent that is indicated for the treatment of clinically important hypotension occurring in the setting of anesthesia.


•	Bloxiverz® (neostigmine methylsulfate injection), a cholinesterase inhibitor, is indicated for the reversal of the effects of non-depolarizing neuromuscular blocking agents (NMBAs) after surgery.


•	Vazculep® (phenylephrine hydrochloride injection), an alpha-1 adrenergic receptor agonist indicated for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia.

Each of our Akovaz, Bloxiverz and Vazculep products is used primarily in the hospital setting and was developed under our UMD program.

The Company was incorporated on December 1, 2015 as an Irish private limited company, and re-registered as an Irish public limited company, or plc, on November 21, 2016. Our principal place of business is located at Block 10-1, Blanchardstown Corporate Park, Ballycoolin, Dublin 15, Ireland. Avadel’s phone number is 011-353-1-485-1200. Our website is www.avadel.com, where we make available free of charge our reports (and any amendments thereto) on Forms 10-K, 10-Q and 8-K as soon as reasonably practicable after they are electronically filed with or furnished to the U.S. Securities and Exchange Commission (“SEC”). These filings are also available to the public at www.sec.gov.

The Company is the successor to Flamel Technologies S.A., a French société anonyme (“Flamel”), as the result of the France-to-Ireland redomestication merger of Flamel with and into the Company completed on December 31, 2016 (the “Merger”). In the Merger, we changed our company name to Avadel Pharmaceuticals plc and our jurisdiction of organization to Ireland; we assumed all the assets and liabilities of Flamel; and we issued one Avadel ordinary share (either directly or in the form of an American Depositary Share (ADS)) in exchange for each formerly outstanding share of Flamel, all of which were canceled. Thus, an Avadel ordinary share held (either directly or represented by an ADS) immediately after the Merger continued to represent the same proportional interest in our equity owned by the holder of a share of Flamel immediately prior to the Merger. References in this Annual Report on Form 10-K to “Avadel,” the “Company,” “we,” “our,” “us,” and similar terms shall be deemed to be references to Flamel prior to the completion of the Merger, unless the context otherwise requires. Additional details about the Merger are set forth in Item 1 under the caption “The Reincorporation Merger” of the Company’s Annual Report on Form 10-K filed with the SEC on March 15, 2019.

The Company currently has five direct wholly-owned subsidiaries: (a) Avadel US Holdings, Inc., (b) Flamel Ireland Limited, which conducts business under the name Avadel Ireland, (c) Avadel Investment Company Limited, (d) Avadel Finance Ireland Designated Activity Company and (e) Avadel France Holding SAS. Avadel US Holdings, Inc., a Delaware corporation, is the holding entity of (i) Avadel Specialty Pharmaceuticals, LLC (currently the subject of a voluntary Chapter 11 bankruptcy proceeding as noted in Note 3: Subsidiary Bankruptcy and Deconsolidation), (ii) Avadel Legacy Pharmaceuticals, LLC, (iii) Avadel Management Corporation, (iv) FSC Holding Company and (v) Avadel Operations Company, Inc. Avadel Finance Ireland Designated Activity Company is the holding entity of Avadel Finance Cayman Limited. Flamel Ireland Limited (operating under the trade name Avadel Ireland) is an Irish corporation which, since December 16, 2014, has been the owner of substantially all of Avadel’s intellectual property. Avadel France Holding SAS, a French société par actions simplifiée, is the holding entity of Avadel Research SAS through which Avadel conducts substantially all of its R&D activities.

Basis of Presentation. The unaudited condensed consolidated balance sheet as of June 30, 2019, which is derived from the prior year 2018 audited consolidated financial statements, and the interim unaudited condensed consolidated financial statements presented herein, have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP), the requirements of Form 10-Q and Article 10 of Regulation S-X and, consequently, do not include all information or footnotes required by U.S. GAAP for complete financial statements or all the disclosures normally made in an annual report on Form 10-K. Accordingly, the unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and footnotes included in the Company’s 2018 Annual Report on Form 10-K filed with the SEC on March 15, 2019.

The unaudited condensed consolidated financial statements include the accounts of the Company and subsidiaries, and reflect all adjustments (consisting only of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the dates and periods presented. All material intercompany accounts and transactions have been eliminated. Results for interim periods are not necessarily indicative of the results to be expected during the remainder of the current year or for any future period.

On February 6, 2019, the Company’s indirect wholly-owned subsidiary, Avadel Specialty Pharmaceuticals, LLC (“Specialty Pharma”), filed a voluntary petition for reorganization under Chapter 11 of the United States (“U.S.”) Code (the “Bankruptcy Code”). in the U.S. District Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”), Case No. 19-10248. Specialty Pharma is operating and managing its business as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and order of the Bankruptcy Court. As a result of Specialty Pharma’s voluntary bankruptcy filing on February 6, 2019, we no longer controlled the operations of Specialty Pharma; therefore, we deconsolidated Specialty Pharma effective with the bankruptcy filing and the Company recorded its investment in Specialty Pharma under the cost method. See Note 3: Subsidiary Bankruptcy and Deconsolidation. Our results of operations for the period January 1, 2019 through February 6, 2019 include the results of Specialty Pharma prior to its February 6, 2019 voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code.

Our results of operations for the period January 1, 2018 through February 16, 2018 include the results of FSC Therapeutics and FSC Laboratories, Inc., (collectively “FSC”), prior to its February 16, 2018 disposition date. See Note 14: Divestiture of the Pediatric Assets, for additional information. All intercompany accounts and transactions have been eliminated.

Revenue. Revenue includes sales of pharmaceutical products, licensing fees, and, if any, milestone payments for research and development (“R&D”) achievements.

Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under ASC 606, an entity recognizes revenue when the performance obligations to the customer have been satisfied through the transfer of control of the goods or services. To determine the appropriate revenue recognition for arrangements that the Company believes are within the scope of ASC 606, we perform the following five steps: (i) Identify the contract(s) with a customer; (ii) Identify the performance obligations in the contract; (iii) Determine the transaction price; (iv) Allocate the transaction price to the performance obligations in the contract; and (v) Recognize revenue when (or as) the entity satisfies a performance obligation. The Company applies the five-step model to contracts only when the Company and its customer’s rights and obligations under the contract can be determined, the contract has commercial substance, and it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. For contracts that are determined to be within the scope of ASC 606, the Company identifies the promised goods or services in the contract to determine if they are separate performance obligations or if they should be bundled with other goods and services into a single performance obligation. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Product Sales and Services

The Company sells products primarily through wholesalers and considers these wholesalers to be its customers. Under ASC 606, revenue from product sales is recognized when the customer obtains control of the Company’s product, which occurs typically upon receipt by the customer. As is customary in the pharmaceutical industry, the Company’s gross product sales are subject to a variety of price adjustments in arriving at reported net product sales. These adjustments include estimates of product returns, chargebacks, payment discounts, rebates, and other sales allowances and are estimated based on analysis of historical data for the product or comparable products, future expectations for such products and other judgments and analysis.

License Revenue

The Company from time to time may enter into out-licensing agreements which are within the scope of ASC 606 under which it licenses to third parties certain rights to its products or intellectual property. The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, upfront license fees; development, regulatory, and commercial milestone payments; and sales-based royalty payments. Each of these payments results in license revenue.
