Zogenix, Inc.
Notes to Condensed Consolidated Financial Statements
 
1.
Organization and Basis of Presentation
Zogenix, Inc. (the Company) is a pharmaceutical company committed to developing and commercializing central nervous system (CNS) therapies that address specific clinical needs for people living with orphan and other CNS disorders who need innovative treatment alternatives to help them improve their daily functioning. The Company's activities are focused on development of two product candidates, ZX008 and Relday, as well as performing contract manufacturing services in accordance with a supply agreement in conjunction with the sale of its Sumavel DosePro business in 2014.
The Company divested its Zohydro ER® business on April 24, 2015 (see Note 4). Zohydro ER activity has been excluded from continuing operations for all periods herein and reported as discontinued operations as a result of the sale.
On July 1, 2015, the Company effected a 1-for-8 reverse stock split of its common stock and changed its authorized shares of common stock to 50,000,000 shares. All historical per share information presented herein has been adjusted to reflect the effect of the reverse stock split and change to the authorized shares of common stock.
2.
Summary of Significant Accounting Policies
Financial Statement Preparation and Use of Estimates
The unaudited condensed consolidated financial statements contained in this Quarterly Report on Form 10-Q have been prepared by the Company according to the rules and regulations of the Securities and Exchange Commission (SEC) and, therefore, certain information and disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been omitted.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements for the periods presented reflect all adjustments, which are normal and recurring, necessary to fairly state the financial position, results of operations and cash flows. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements included in the Company's Annual Report on Form 10-K and Form 10-K/A for the fiscal year ended December 31, 2015, each as filed with the SEC.
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
Principles of Consolidation
The unaudited condensed consolidated financial statements include the accounts of Zogenix, Inc. and its wholly owned subsidiary Zogenix Europe Limited (Zogenix Europe), which was incorporated under the laws of England and Wales in June 2010. All intercompany transactions and investments have been eliminated in consolidation. Zogenix Europe's functional currency is the U.S. dollar which is the reporting currency of the Company.
Restricted Cash
The Company had restricted cash in escrow as of December 31, 2015 to fund potential indemnification claims for 12 months from the closing date of its sale of the Zohydro ER business in April 2015. The Company received the full amount from escrow in April 2016. The Company classifies this cash flow as investing activities in the condensed consolidated statement of cash flows as the source of the restricted cash was related to the sale of the Zohydro ER business.
Fair Value Measurements
The carrying amount of financial instruments consisting of cash, restricted cash, trade accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and accrued compensation included in the Company’s condensed consolidated financial statements are reasonable estimates of fair value due to their short maturities. Based on the borrowing rates currently available to the Company for loans with similar terms, management believes the fair value of long-term debt approximates its carrying value.
Authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
 

6


Level 1:
Observable inputs such as quoted prices in active markets;
Level 2:
Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
Level 3:
Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
The Company classifies its cash equivalents within Level 1 of the fair value hierarchy because it values its cash equivalents using quoted market prices. The Company classifies its common stock warrant liabilities and contingent purchase consideration within Level 3 of the fair value hierarchy because they are valued using valuation models with significant unobservable inputs. Assets and liabilities measured at fair value on a recurring basis at September 30, 2016 and December 31, 2015 are as follows (in thousands):

Cash equivalents are comprised of money market fund shares and are included as a component of cash and cash equivalents on the condensed consolidated balance sheets.
(2)
Common stock warrant liabilities were incurred in connection with the Company's July 2012 public offering of common stock and warrants and with the financing agreement (the Healthcare Royalty financing agreement) entered into with Healthcare Royalty Partners (Healthcare Royalty) (see Note 6), which are measured at fair value using the Black-Scholes option pricing valuation model. The assumptions used in the Black-Scholes option pricing valuation model for both common stock warrant liabilities were: (a) a risk-free interest rate based on the rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the remaining contractual term of the warrants; (b) an assumed dividend yield of zero based on the Company’s expectation that it will not pay dividends in the foreseeable future; (c) an expected term based on the remaining contractual term of the warrants; and (d) expected volatility based upon the Company's historical volatility. The significant unobservable input used in measuring the fair value of the common stock warrant liabilities associated with the Healthcare Royalty financing agreement is the expected volatility. Significant increases in volatility would result in a higher fair value measurement. The following additional assumptions were used in the Black-Scholes option pricing valuation model to measure the fair value of the warrants sold in the July 2012 public offering: (a) management's projections regarding the probability of the occurrence of an extraordinary event and the timing of such event; and for the valuation scenario in which an extraordinary event occurs that is not an all cash transaction or an event whereby a public acquirer would assume the warrants, and (b) an expected volatility rate using the Company's historical volatility through the projected date of public announcement of an extraordinary transaction, blended with a rate equal to the lesser of 40% and the 180-day volatility rate obtained from the HVT function on Bloomberg as of the trading day immediately following the public announcement of an extraordinary transaction. The significant unobservable inputs used in measuring the fair value of the common stock warrant liabilities associated with the July 2012 public offering are the expected volatility and the probability of the occurrence of an extraordinary event. Significant increases in volatility would result in a higher fair value measurement and significant increases in the probability of an extraordinary event occurring would result in a significantly lower fair value measurement. The change in the fair value of the common stock

7


warrant liabilities as of September 30, 2016 was primarily driven by the decrease in the market price of the Company's common shares at September 30, 2016 as compared against the December 31, 2015 measurement date.
(3)
Contingent purchase consideration was measured at fair value using the income approach based on significant unobservable inputs including management's estimates of the probabilities of achieving specific net sales levels and development milestones and appropriate risk adjusted discount rates. Significant changes of either unobservable input could have a significant effect on the calculation of fair value of the contingent purchase consideration liability.
The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) for the nine months ended September 30, 2016 (in thousands):

Net Income (Loss) per Share
Basic and diluted net loss per share is calculated by dividing the net income (loss) by the weighted average number of common shares outstanding for the period without consideration for common stock equivalents. Common stock equivalents that could potentially reduce net earnings per common share in the future that were not included in the determination of diluted net income (loss) per common share as their effects were antidilutive are as follows (in thousands):

Other Comprehensive Income (Loss)
The Company received shares of Pernix Therapeutics Holdings, Inc. common stock received as partial consideration for the sale of the Zohydro ER business in April 2015. The Company liquidated all of these investments during the fourth quarter of 2015.
Management classifies short-term investments as available-for-sale when acquired and evaluated such classification as of each balance sheet date. Short-term investments are carried at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive income (loss), a component of stockholders’ equity. The Company evaluates its short-term investments to assess whether any unrealized loss position is other than temporarily impaired. Impairment is considered to be other than temporary if it is likely that the Company intended to sell the investments before the recovery of the cost basis. The Company recorded impairment charges of $5,485,000 for the three and nine months ended September 30, 2015.
Realized gains, losses, and declines in value judged to be other than temporary were reported in other income (expense) in the condensed consolidated statements of operations and comprehensive income (loss).
Goodwill and Intangible Assets
Goodwill represents the excess of acquisition cost over the fair value of the net assets of acquired businesses. Goodwill
has an indefinite useful life and is not amortized, but instead tested for impairment annually. Intangible assets consist of in-process research and development with an indefinite useful life that is not amortized, but instead tested for impairment until the successful completion and commercialization or abandonment of the associated research and development efforts, at which point the in-process research and development asset is either amortized over its estimated useful life or written-off immediately.

8


Impairment of Long-Lived Assets
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.
Revenue Recognition
The Company recognizes revenue from contract manufacturing, service fees earned on collaborative arrangements and the sale of Sumavel DosePro prior to its sale in May 2014. The Company also recognizes revenue from the sale of Zohydro ER, which is included in net loss from discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss). Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred and title has passed, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured. Revenue from sales transactions where the buyer has the right to return the product is recognized at the time of sale only if (a) the Company’s price to the buyer is substantially fixed or determinable at the date of sale, (b) the buyer has paid the Company, or the buyer is obligated to pay the Company and the obligation is not contingent on resale of the product, (c) the buyer’s obligation to the Company would not be changed in the event of theft or physical destruction or damage of the product, (d) the buyer acquiring the product for resale has economic substance apart from that provided by the Company, (e) the Company does not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (f) the amount of future returns can be reasonably estimated. The Company deferred recognition of revenue on product shipments of Zohydro ER until the right of return no longer exists, as the Company was not able to reliably estimate expected returns of the product at the time of shipment given the limited sales history of Zohydro ER.
Revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer. The consideration received is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units. The application of the multiple element guidance requires subjective determinations, and requires the Company to make judgments about the individual deliverables and whether such deliverables are separable from the other aspects of the contractual relationship. Deliverables are considered separate units of accounting provided that: (1) the delivered item(s) has value to the customer on a stand-alone basis and (2) if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the Company's control. In determining the units of accounting, the Company evaluates certain criteria, including whether the deliverables have stand-alone value, based on the consideration of the relevant facts and circumstances for each arrangement. In addition, the Company considers whether the buyer can use the other deliverable(s) for their intended purpose without the receipt of the remaining element(s), whether the value of the deliverable is dependent on the undelivered item(s), and whether there are other vendors that can provide the undelivered element(s).
Arrangement consideration that is fixed or determinable is allocated among the separate units of accounting using the relative selling price method, and the applicable revenue recognition criteria, as described above, are applied to each of the separate units of accounting in determining the appropriate period or pattern of recognition. The Company determines the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (VSOE) of selling price, if available, third-party evidence (TPE) of selling price if VSOE is not available, or management's best estimate of selling price (BESP) if neither VSOE nor TPE is available. Determining the BESP for a unit of accounting requires significant judgment. In developing the BESP for a unit of accounting, the Company considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs.
Contract Manufacturing Revenue
The Company and Endo entered into a supply agreement in connection with the sale of the Sumavel DosePro business to Endo in May 2014. Under the terms of the supply agreement, the Company retains the sole and exclusive right and the obligation to manufacture or supply Sumavel DosePro to Endo. The Company recognizes deferred revenue related to its supply of Sumavel DosePro as contract manufacturing revenue when earned on a "proportional performance" basis as product is delivered. The Company recognizes revenue related to its sale of Sumavel DosePro product, equal to the cost of contract manufacturing plus a low single-digit mark-up, upon the transfer of title to Endo. The Company supplies Sumavel DosePro product based on non-cancellable purchase orders. The Company initially defers revenue for any consideration received in advance of services being performed and product being delivered, and recognizes revenue pursuant to the related pattern of performance, based on total product delivered relative to the total estimated product delivery over the minimum eight-year term of the supply agreement ending in May 2022. The Company continually evaluates the performance period and adjusts the period of revenue recognition if circumstances change. The Company recognized $(200,000) and $600,000 of contract manufacturing revenue in continuing operations during the three and nine months ended September 30, 2016, respectively,

9


based on changes in estimated product to be delivered during the remaining term of the supply agreement. The effect of the changes in estimated future product delivery increased both total net loss per share from continuing operations and net loss per share by $0.01 for the three months ended September 30, 2016, and decreased both total net loss per share from continuing operations and net loss per share by $0.02 for the nine months ended September 30, 2016.
In addition, the Company reports revenue as gross when the Company acts as a principal versus reporting revenue as net when the Company acts as an agent. For transactions in which the Company acts as a principal, has discretion to choose suppliers, bears credit risk and performs a substantive part of the services, revenue is recorded at the gross amount billed to a customer and costs associated with these reimbursements are reflected as a component of cost of sales for contract manufacturing services.
Product Revenue, Net
The Company sold Sumavel DosePro through May 2014, and sold Zohydro ER through April 2015, in the United States to wholesale pharmaceutical distributors and retail pharmacies, or collectively the Company's customers, subject to rights of return within a period beginning six months prior to, and ending 12 months following, product expiration. The Company recognized Sumavel DosePro product sales at the time title transferred to its customer, and reduced product sales for estimated future product returns and sales allowances in the same period the related revenue was recognized. The Company is responsible for all returns of Sumavel DosePro product distributed by the Company prior to the sale of the Sumavel DosePro business up to a maximum per unit amount as specified in the sales agreement.
Given the limited sales history of Zohydro ER, the Company was not able to reliably estimate expected returns of the product at the time of shipment. Accordingly, the Company deferred recognition of revenue on Zohydro ER product shipments until the right of return no longer exists, which occurs at the earlier of the time Zohydro ER is dispensed through patient prescriptions or expiration of the right of return. The Company estimates Zohydro ER patient prescriptions dispensed using an analysis of third-party syndicated data. Zohydro ER was launched in March 2014 and, accordingly, the Company did not have a significant history estimating the number of patient prescriptions dispensed. If the Company underestimated or overestimated patient prescriptions dispensed for a given period, adjustments to revenue from discontinued operations may be necessary in future periods. The deferred revenue balance does not have a direct correlation with future revenue recognition as the Company records sales deductions at the time the prescription unit was dispensed. In addition, the costs of Zohydro ER associated with the deferred revenue were recorded as deferred costs, which were included in inventory, until such time the related deferred revenue is recognized. The Company is responsible for returns for product sold prior to the sale of the business on April 24, 2015 and was responsible for rebates, chargebacks, and related fees for product sold until July 8, 2015 per terms of the asset purchase agreement (the Asset Purchase Agreement) the Company entered into with Pernix Ireland Limited and Pernix Therapeutics (collectively, Pernix). Revenue for Zohydro ER is included in discontinued operations in the condensed consolidated statements of operations and comprehensive income (loss).
Segment Reporting
Management has determined that the Company operates in one business segment, which is the development and commercialization of pharmaceutical products.
Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (FASB) issued new accounting guidance related to revenue recognition, and in April 2016 and May 2016 the FASB issued additional guidance related to revenue recognition. These new standards will replace all current GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The guidance will be effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period, and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. Early adoption of the guidance is permitted on the original effective date of fiscal years beginning after December 15, 2016. The Company is evaluating the transition method, timing and impact of adopting these new accounting standards on its financial statements and related disclosures.
In August 2014, the FASB issued new accounting guidance which requires management to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and provide related footnote disclosures. The guidance is effective for annual and interim reporting periods beginning on or after December 15, 2016. Early adoption is permitted. The

10


Company does not expect that the adoption of the guidance will have a material impact on the Company’s consolidated financial statements.
In February 2016, the FASB issued guidance by requiring lessees to recognize the lease assets and lease liabilities that arise from both capital and operating leases with lease terms of more than 12 months and to disclose qualitative and quantitative information about lease transactions. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the timing and impact of adopting this new accounting standard on its financial statements and related disclosures.
In March 2016, the FASB issued guidance to revise accounting for share-based compensation arrangements, including the income tax impact and classification on the statement of cash flows.  The standard is effective for annual and interim periods beginning after December 15, 2016. The Company is currently evaluating the impact the adoption of this standard will have on its condensed consolidated financial statements.
In August 2016, the FASB issued guidance to clarify the classification of certain cash receipts and cash payments on the statement of cash flows with the objective of reducing the existing diversity in practice related to specific cash flow issues. The amendments in this update are effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

Discontinued operations

On March 10, 2015, the Company entered into the Asset Purchase Agreement whereby the Company agreed to sell its Zohydro ER business to Pernix, and on April 24, 2015, the Company completed the sale to Ferrimill Limited, a subsidiary of Pernix, as a substitute purchaser.
As a result of the Company's strategic decision to sell the Zohydro ER business and focus on clinical development of ZX008 and Relday, the financial results from the Zohydro ER business and the related assets and liabilities have been presented as discontinued operations in the condensed consolidated financial statements. The results of operations from discontinued operations presented below include certain allocations that management believes fairly reflect the utilization of services provided to the Zohydro ER business. The allocations do not include amounts related to general corporate administrative expenses or interest expense, and therefore the results of operations from the Zohydro ER business do not necessarily reflect what the results of operations would have been had the business operated as a stand-alone entity.
The following table summarizes the results of discontinued operations for the periods presented in the condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2016 and 2015 (in thousands):

Amendment of Loan and Security Agreement
On June 17, 2016, the Company entered into a second amendment to modify the loan and security agreement with Oxford Finance LLC and Silicon Valley Bank dated as of December 30, 2014. Significant terms of the modification included:
providing the Company with additional term loans in net aggregate principal amount of $3,333,334;

Table of Contents

amending the original repayment schedule of the term loans such that the Company is required to make interest-only payments until February 1, 2018, then equal monthly payments of principal plus interest will be made through the maturity date of the term loans on July 1, 2020;
amending the interest rate such that the term loans bear interest at an annual rate equal to either (i) 7.00% or (ii) the sum of (a) the “prime rate” rate reported in the Wall Street Journal on the date occurring on the last business day of the month that immediately precedes the month in which the interest will accrue, plus (b) 3.25%, whichever is greater;
removing the revolving line of credit previously available under the original loan and security agreement;
removing an affirmative covenant requiring the Company to maintain a liquidity ratio of 1.25 to 1 through the Company’s receipt of positive data from placebo-controlled trials in the United States and European Union of ZX008; and
amending a covenant to now permit the Company to maintain collateral account balances exceeding the greater of (i) $50,000,000, or (ii) 50% of the Company’s total collateral account balances (other than specifically excluded accounts), with financial institutions other than the lenders; provided that, if the Company’s total collateral account balances are below $50,000,000, all such balances will be maintained with the lenders.
In connection with second amendment, the Company paid (i) a final payment of $1,000,000 with respect to the existing term loans, previously due on the earlier to occur of the maturity date of the original loan and security agreement or early repayment of the term loans; (ii) an amendment fee of $25,000 with respect to a previous loan amendment; and (iii) revolving line commitment fees of $64,000 due relative to the termination of the revolving line of credit. Furthermore, the Company agreed to make a final payment of $1,350,000 on the earlier of the maturity date of the amended loan and security agreement or early repayment of the term loans, and to pay a termination fee of $200,000 on the earlier to occur of a change in control or the early termination of the loan and security agreement.

Common Stock Warrant Liability
In July 2012, in connection with a public offering of common stock and warrants, the Company sold warrants to purchase 1,973,025 shares of common stock and at September 30, 2016, warrants to purchase 1,901,918 shares of common stock are outstanding. The warrants are exercisable at an exercise price of $20.00 per share and will expire on July 27, 2017. As the warrants contain a cash settlement feature upon the occurrence of certain events that may be outside of the Company’s control, the warrants are recorded as a current liability and are marked to market at each reporting period (see Note 2). None of these warrants were exercised during the three or nine months ended September 30, 2016 or the year ended December 31, 2015. The fair value of the warrants outstanding was approximately $968,000 and $6,069,000 as of September 30, 2016 and December 31, 2015, respectively.
In July 2011, upon the closing of and in connection with the Healthcare Royalty financing agreement, the Company issued a warrant to Healthcare Royalty exercisable into 28,125 shares of common stock. The warrant is exercisable at $72.00 per share of common stock and has a term of ten years. As the warrant contains covenants where compliance with such covenants may be outside of the Company’s control, the warrant was recorded as a current liability and is marked to market at each reporting date (see Note 2). The fair value of the warrant was approximately $80,000 and $127,000 as of September 30, 2016 and December 31, 2015, respectively.

Stock-Based Compensation
The Company uses the Black-Scholes option-pricing model for determining the estimated fair value of stock-based compensation for stock-based awards to employees and the board of directors. The assumptions used in the Black-Scholes option-pricing model for the three and nine months ended September 30, 2016 and 2015 are as follows:

of not paying dividends in the foreseeable future. The weighted average expected term of options was calculated using the simplified method as prescribed by accounting guidance for stock-based compensation based on the lack of relevant historical data due to the Company’s limited historical experience. In addition, due to the Company’s limited historical data, the estimated volatility was calculated based upon the Company's historical volatility, supplemented with historical volatility of comparable companies whose share prices are publicly available for a sufficient period of time.
The Company recognized stock-based compensation expense in continuing operations as follows (in thousands):

As of September 30, 2016, there was approximately $10,915,000 of total unrecognized compensation costs related to outstanding employee and board of director stock options which is expected to be recognized over a weighted average period of 2.5 years, and $670,000 of total unrecognized compensation costs related to unvested employee performance stock units which is expected to be recognized over a weighted average period of 1.5 years.
As of September 30, 2016, there were 35,771 unvested stock options and 7,500 unvested restricted stock units outstanding to consultants, with approximately $352,000 of related unrecognized compensation expense based on a September 30, 2016 measurement date. These unvested stock awards outstanding to consultants are expected to vest over a weighted average period of 2.7 years. In accordance with accounting guidance for stock-based compensation, the Company remeasures the fair value of stock option grants to non-employees at each reporting date and recognizes the related income or expense during their vesting period. The expense recognized from the revaluation of stock options and restricted stock units to consultants was immaterial for the three and nine months ended September 30, 2016 and 2015. The expense for awards issued to consultants is included in the condensed consolidated statements of operations and comprehensive income (loss) within selling, general and administrative expense.

Income taxes

The Company recorded a tax benefit to continuing operations of $1,025,000 for the three and nine months ended September 30, 2016 related to tax rate reductions enacted in the United Kingdom in September 2016 which resulted in a decrease in the Company's deferred tax liability.
Intraperiod tax allocation rules require the Company to allocate the provision for income taxes between continuing operations and other categories of earnings, such as discontinued operations. In periods in which the Company has a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as discontinued operations, the Company must allocate the tax provision to the other categories of earnings, and then record a related tax benefit in continuing operations. During the three and nine months ended September 30, 2016, the Company recognized net losses from both continuing and discontinued operations, and therefore no allocation of income tax was required. During the three and nine months ended September 30, 2015 the Company recognized net income from discontinued operations, and, as a result, recorded income tax expense of $2,520,000 and $15,998,000, respectively, which is included in net income (loss) from discontinued operations in the condensed consolidated statement of operations and comprehensive income (loss). Accordingly, the Company recognized a related income tax benefit of $5,496,000 and $12,428,000 from continuing operations in the condensed consolidated statement of operations and comprehensive income (loss) for the three and nine months ended September 30, 2015, respectively. The remaining $3,535,000 income tax benefit to continuing operations was recognized throughout the remainder of 2015.

Subsequent events

In October 2016, the Company completed an asset purchase agreement to acquire the global rights to a preclinical development program for orphan CNS disorders for $1,500,000. Under the asset purchase agreement, the Company is also obligated to make future milestone payments based on the successful achievement of certain defined development and sales milestones. The accounting for this transaction and estimated financial effect of these development milestones are being evaluated. Due to the preclinical stage of development and the nature of this arrangement, the future potential payments related to the attainment of the specified milestones over a period of several years are inherently uncertain.
In October 2016, the Company amended its manufacturing services agreement with Patheon UK Limited to extend the term of the existing agreement through April 2017. Other terms of the existing agreement remain unchanged. The agreement may be extended further by agreement of both parties for additional terms prior to the expiration of the current term. Future minimum purchase commitments total $4,600,000 at September 30, 2016 through the term of the extended agreement.

Overview
Background
We are a pharmaceutical company committed to developing and commercializing central nervous system, or CNS, therapies that address specific clinical needs for people living with orphan and other CNS disorders who need innovative treatment alternatives to help them improve their daily functioning. Our current areas of focus are epilepsy and schizophrenia.
Our lead product candidate is ZX008, low-dose fenfluramine for the treatment of seizures associated with Dravet syndrome. Dravet syndrome is a rare and catastrophic form of pediatric epilepsy with life threatening consequences for patients and for which current treatment options are very limited. ZX008 has received orphan drug designation in the United States and Europe for the treatment of Dravet syndrome. In January 2016, we received notification of Fast Track designation from the U.S. Food and Drug Administration, or FDA, for ZX008 for the treatment of Dravet syndrome. We initiated Phase 3 clinical trials in January 2016 in the United States, and we initiated Phase 3 clinical trials in Europe in June 2016. We expect top-line results from these trials in the second quarter of 2017. Additionally, we initiated the enrollment of patients in our European study of Dravet syndrome patients who are poor responders to a stiripentol treatment regime in the third quarter of this year. We obtained worldwide development and commercialization rights to ZX008 through our acquisition of Zogenix International Limited in October 2014.
We have an additional product candidate in development, ReldayTM (risperidone once-monthly long-acting injectable) for the treatment of schizophrenia. Relday is a proprietary, long-acting injectable formulation of risperidone. Risperidone is used to treat the symptoms of schizophrenia and bipolar disorder in adults and teenagers 13 years of age and older. We began enrolling patients in a Phase 1b multi-dose clinical study for Relday in March 2015. On September 30, 2015, we announced positive top-line pharmacokinetic results from the Phase 1b study. Efforts with a third-party transaction advisory firm to help secure a global strategic development and commercialization partner for Relday are ongoing.
We sold our Zohydro ER® business in April 2015 to enable us to focus on development of our CNS product candidates and to enhance our financial strength. Zohydro ER (hydrocodone bitartrate) is an extended-release capsule oral formulation of hydrocodone without acetaminophen.
We sold our Sumavel® DosePro® (sumatriptan injection) Needle-free Delivery System business in May 2014 to Endo International Plc, or Endo. In connection with the sale, we entered into a supply agreement, or the Supply Agreement, pursuant to which we retain the sole and exclusive right and obligation to manufacture Sumavel DosePro for Endo, subject to Endo’s right to qualify and maintain a back-up manufacturer.

On March 10, 2015, we entered into an asset purchase agreement with Pernix Ireland Limited and Pernix Therapeutics, or collectively, Pernix, whereby we agreed to sell our Zohydro ER business to Pernix, and on April 24, 2015, we completed the sale to Ferrimill Limited, an Irish corporation and subsidiary of Pernix, as a substitute purchaser. The Zohydro ER business divested included the registered patents and trademarks, certain contracts, the new drug application, or NDA, and other regulatory approvals, documentation and authorizations, the books and records, marketing materials and product data relating to Zohydro ER. We received consideration of $80.0 million in cash and $10.6 million in Pernix Therapeutics common stock. Further, Ferrimill purchased Zohydro ER inventory from us of $0.9 million and we received consideration for discounts received by Ferrimill based on an assigned supply agreement of $2.4 million. We agreed to indemnify the purchaser for certain intellectual property matters up to an aggregate amount of $5.0 million.
In addition to the cash payments received, we are eligible to receive additional cash payments of up to $283.5 million based on the achievement of pre-determined milestones, including a $12.5 million payment upon approval by the FDA of an abuse-deterrent extended-release hydrocodone tablet (currently in development in collaboration with Altus Formulation Inc.) and up to $271.0 million in potential sales milestones. The purchaser will assume responsibility for our obligations under the purchased contracts and regulatory approvals, as well as other liabilities associated with the Zohydro ER business arising after the sale date.
On April 23, 2015, in connection with the sale of the Zohydro ER business, we, Oxford Finance LLC, or Oxford, and Silicon Valley Bank, or SVB, entered into an amendment to the loan and security agreement dated December 30, 2014 which added an affirmative covenant requiring a liquidity ratio of 1.25 to 1 through our receipt of positive data from placebo-controlled trials in the United States and European Union of ZX008 and terminated all encumbrances on our personal property related to its Zohydro ER business. The remaining obligations under the loan and security agreement remained substantially unchanged.
On June 17, 2016, we, Oxford and SVB entered into a second amendment to the loan and security agreement dated December 30, 2014 which provided additional net term loan proceeds of $3.3 million, extended the original repayment

schedule of the term loans such that we are required to make interest-only payments until February 17, 2018, then equal monthly payments of principal plus interest will be made through the maturity date of the term loans on July 1, 2020, reduced the interest rate on the term loans, removed the revolving line of credit previously available, amended the collateral account covenant and removed the liquidity covenant as discussed in the preceding paragraph.
Endo Ventures Bermuda Limited and Endo Ventures Limited Asset Purchase Agreement
On April 23, 2014, we sold our Sumavel DosePro business to Endo, including the registered trademarks, certain contracts, the NDA, and other regulatory approvals, the books and records, marketing materials and product data relating to Sumavel DosePro pursuant to an asset purchase agreement. Under the terms of the sale, Endo paid us $85.0 million in cash, $8.5 million of which was deposited into escrow and which we received in May 2015. Further, Endo Ventures Limited, or Endo Ventures, purchased from us our finished goods inventory of Sumavel DosePro for $4.6 million. In addition to the upfront cash payment, we are eligible to receive additional cash payments of up to $20.0 million based on the achievement of pre-determined sales and gross margin milestones. Furthermore, Endo Ventures assumed responsibility for our royalty obligation on sales of Sumavel DosePro and assumed other liabilities relating to Sumavel DosePro after the sale.
In addition, we and Endo Ventures Bermuda Limited also entered into a license agreement, pursuant to which we granted Endo Ventures an exclusive, worldwide, royalty-free license for Sumavel DosePro. We also entered into the Supply Agreement with Endo Ventures, pursuant to which we will continue to manufacture Sumavel DosePro, and Endo Ventures supported our Sumavel DosePro manufacturing operations with a working capital advance of $7.0 million.
In connection with the sale, we were required to extinguish all encumbrances on the assets to be sold to Endo, including those previously granted to Healthcare Royalty Partners, or Healthcare Royalty, pursuant to the financing agreement, dated June 30, 2011, with Healthcare Royalty, or the Healthcare Royalty financing agreement. We eliminated our existing debt obligation to Healthcare Royalty in May 2014 by paying $40.0 million to Healthcare Royalty which was consistent with the terms of the Healthcare Royalty financing agreement.
Critical Accounting Policies and Estimates
We recognize revenue from contract manufacturing, service fees earned on collaborative arrangements and the sale of Sumavel DosePro prior to its sale in May 2014. We also recognize revenue from the sale of Zohydro ER which is included in net loss from discontinued operations in the condensed consolidated statements of operations and comprehensive loss. Revenue is recognized when (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred and title has passed, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured. Revenue from sales transactions where the buyer has the right to return the product is recognized at the time of sale only if (a) our price to the buyer is substantially fixed or determinable at the date of sale, (b) the buyer has paid us, or the buyer is obligated to pay us and the obligation is not contingent on resale of the product, (c) the buyer’s obligation to us would not be changed in the event of theft or physical destruction or damage of the product, (d) the buyer acquiring the product for resale has economic substance apart from that provided by us, (e) we do not have significant obligations for future performance to directly bring about resale of the product by the buyer, and (f) the amount of future returns can be reasonably estimated. We defer recognition of revenue on product shipments of Zohydro ER until the right of return no longer exists, as we were not able to reliably estimate expected returns of the product at the time of shipment given the limited sales and return history of Zohydro ER.
Revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer. The consideration received is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units. The application of the multiple element guidance requires subjective determinations, and requires us to make judgments about the individual deliverables and whether such deliverables are separable from the other aspects of the contractual relationship. Deliverables are considered separate units of accounting provided that: (1) the delivered item(s) has value to the customer on a stand-alone basis and (2) if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. In determining the units of accounting, we evaluate certain criteria, including whether the deliverables have stand-alone value, based on the consideration of the relevant facts and circumstances for each arrangement. In addition, we consider whether the buyer can use the other deliverable(s) for their intended purpose without the receipt of the remaining element(s), whether the value of the deliverable is dependent on the undelivered item(s), and whether there are other vendors that can provide the undelivered element(s).
Arrangement consideration that is fixed or determinable is allocated among the separate units of accounting using the relative selling price method, and the applicable revenue recognition criteria, as described above, are applied to each of the separate units of accounting in determining the appropriate period or pattern of recognition. We determine the estimated selling

18

Table of Contents

price for deliverables within each agreement using vendor-specific objective evidence, or VSOE, of selling price, if available, third-party evidence, or TPE, of selling price if VSOE is not available, or management's best estimate of selling price, or BESP, if neither VSOE nor TPE is available. Determining the BESP for a unit of accounting requires significant judgment. In developing the BESP for a unit of accounting, we consider applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated costs.
Contract Manufacturing Revenue
We and Endo Ventures entered into the Supply Agreement in connection with the sale of the Sumavel DosePro business to Endo in May 2014. Under terms of the Supply Agreement, we retain the sole and exclusive right and the obligation to manufacture or supply Sumavel DosePro to Endo. We recognize deferred revenue related to our supply of Sumavel DosePro as contract manufacturing revenue when earned on a "proportional performance" basis as product is delivered. We recognize revenue related to our sale of Sumavel DosePro product, equal to the cost of contract manufacturing plus a low single-digit mark-up, upon the transfer of title to Endo. We supply Sumavel DosePro product based on non-cancellable purchase orders. We initially defer revenue for any consideration received in advance of services being performed and product being delivered, and recognize revenue pursuant to the related pattern of performance, based on total product delivered relative to the total estimated product delivery over the minimum eight year term of the Supply Agreement ending in May 2022. We continually evaluate the performance period and will adjust the period of revenue recognition if circumstances change. The Company recognized ($0.2) million and $0.6 million of contract manufacturing revenue in continuing operations during the three and nine months ended September 30, 2016, respectively, based on changes in estimated product to be delivered during the remaining term of the supply agreement. The effect of the changes in estimated future product delivery increased both total net loss per share from continuing operations and net loss per share by $0.01 for the three months ended September 30, 2016, and decreased both total net loss per share from continuing operations and net loss per share by $0.02 for the nine months ended September 30, 2016.
In addition, we report revenue gross when we act as a principal versus reporting revenue as net when we act as an agent. For transactions in which we act as a principal, have discretion to choose suppliers, bear credit risk and perform a substantive part of the services, revenue is recorded at the gross amount billed to a customer and costs associated with these reimbursements are reflected as a component of cost of sales for contract manufacturing services.
Product Revenue, Net
We sold Sumavel DosePro through May 2014, and sold Zohydro ER until its purchase in April 2015, in the United States to wholesale pharmaceutical distributors and retail pharmacies, or collectively our customers, subject to rights of return within a period beginning six months prior to, and ending 12 months following, product expiration. We recognized Sumavel DosePro product sales at the time title transferred to our customer, and we reduced product sales for estimated future product returns and sales allowances in the same period the related revenue was recognized. We are responsible for all returns of Sumavel DosePro product distributed by us prior to sale up to a maximum per unit amount as specified in the sale agreement.
Given the limited sales history of Zohydro ER, we could not reliably estimate expected returns of the product at the time of shipment. Accordingly, we deferred recognition of revenue on Zohydro ER product shipments until the right of return no longer exists, which occurs at the earlier of the time Zohydro ER was dispensed through patient prescriptions or expiration of the right of return. We estimated Zohydro ER patient prescriptions dispensed using an analysis of third-party syndicated data. Zohydro ER was launched in March 2014 and, accordingly, we did not have a significant history estimating the number of patient prescriptions dispensed. If we underestimated or overestimated patient prescriptions dispensed for a given period, adjustments to revenue from discontinued operations may be necessary in future periods.
Fair Value Measurements
U.S. generally accepted accounting principles, or GAAP, require us to estimate the fair value of certain assets and liabilities as of the date of their acquisition or incurrence, on an ongoing basis, or both. Determining the fair value of an asset or liability, such as our acquired in-process research and development, contingent purchase consideration and warrants for common stock requires the use of accounting estimates and assumptions which are judgmental in nature and could have a significant impact on the determination of the amount of the fair value ascribed to the asset or liability.
There have been no significant changes in critical accounting policies during the three months ended September 30, 2016 as compared to the critical accounting policies described in “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” in our Annual Report on Form 10-K for the year ended December 31, 2015.

Contract manufacturing revenue is recognized for Sumavel DosePro finished goods inventory that has been delivered to Endo Ventures Bermuda under the Supply Agreement, and includes a portion of deferred revenue recognized on a proportional performance method. Endo Ventures Bermuda pays us the costs associated with production of Sumavel DosePro plus a contractual mark-up for Sumavel DosePro product delivered under the terms of our Supply Agreement. The decrease in contract manufacturing revenue for the three and nine months ended September 30, 2016 as compared the same periods in 2015 was primarily as a result of decreases in costs of contract manufacturing billed to Endo under the terms of our Supply Agreement in 2016 as compared to the same period in 2015, as well as $1.1 million and $0.2 million in lower contract manufacturing revenue recognized based on changes in estimated product to be delivered during the remaining term of the supply agreement for the three and nine months ended September 30, 2016, respectively, as compared to the three and nine months ended September 30, 2015.
Service and other product revenue recorded for the three and nine months ended September 30, 2016 and the three months ended September 30, 2015 consisted of adjustments to estimated Sumavel DosePro returns reserves subsequent to the sale of the business in May 2014. For the nine months ended September 30, 2015, we recognized co-promotion revenue of $0.8 million earned in conjunction with an agreement that terminated in June 2015 in addition to revenue generated from Sumavel DosePro returns reserve adjustments.

Costs of contract manufacturing consists primarily of materials, third-party manufacturing costs, freight and indirect personnel and other overhead costs associated with Sumavel DosePro based on units sold to Endo, as well as the effect of changes in reserves for excess, dated or obsolete commercial inventories and production manufacturing variances. It represents the cost of units recognized as contract manufacturing revenues in the period and the impact of underutilized production capacity and other manufacturing variances. The decrease in cost of contract manufacturing for the three and nine months ended September 30, 2016 as compared to the same periods in 2015 resulted primarily from a decrease in units delivered under our Supply Agreement with Endo, offset by increases in excess capacity and scrap charges.

Royalty expense reflects both the amortization of the milestone payment related to technology that we have licensed and immaterial adjustments to previously estimated royalty liabilities based on actual sales results. We expect royalty expense to remain consistent in the near term as we advance our product development plans.

 Research and development expenses consist of expenses incurred in developing, testing and seeking marketing approval of our product candidates, including license and milestone payments; payments made to third-party clinical research organizations, or CROs, and investigational sites, which conduct our trials on our behalf, and consultants; expenses associated with regulatory submissions, pre-clinical development and clinical trials; payments to third-party manufacturers, which produce our active pharmaceutical ingredient and finished product; personnel related expenses, such as salaries, benefits, travel and other related expenses, including stock-based compensation; and facility, maintenance, depreciation and other related expenses. We expense all research and development costs as incurred.
We utilize CROs, contract laboratories and independent contractors for the conduct of pre-clinical studies and clinical trials. We track third-party costs by type of study being conducted. We recognize the expenses associated with the services provided by CROs based on the percentage of each study completed at the end of each reporting period. We coordinate clinical trials through a number of contracted investigational sites and recognize the associated expense based on a number of factors, including actual and estimated subject enrollment and visits, direct pass-through costs and other clinical site fees.
The table below sets forth information regarding our research and development costs for our major development programs. The period over period changes in our major development programs are explained in the narrative beneath the table.

Other research and development expenses include employee and infrastructure resources that are not tracked on a program-by-program basis as well as development costs incurred for other product candidates.
We acquired ZX008 with our acquisition of Zogenix International Limited in October 2014 and have subsequently incurred expenses as we proceed with our Phase 3 clinical trials for ZX008 which commenced in January 2016. Expenses for Relday decreased for the three and nine months ended September 30, 2016 as compared to the same period in 2015 as we initiated a multi-dose clinical study for Relday in the first quarter of 2015 which concluded later in 2015. We use our employee and infrastructure resources across our product and product candidate development programs. Therefore, we have not tracked salaries, other personnel related expenses, facilities or other related costs to our product development activities on a program-by-program basis.
We expect our research and development expenses for the remainder of 2016 to exceed amounts incurred in the same period in 2015 as we continue to conduct our Phase 3 studies for ZX008.

 Selling expense consists primarily of salaries and benefits of sales and marketing management and market research expenses for product candidates that are in development. General and administrative expenses consist primarily of salaries and related costs for personnel in executive, finance, accounting, business development and internal support functions. In addition, general and administrative expenses include professional fees for legal, consulting and accounting services.
Selling expense increased for the three and nine months ended September 30, 2016 from the same periods in 2015 due primarily to market research and pre-commercial analysis expenses related to ZX008. General and administrative expenses increased for the three months ended September 30, 2016 as compared to the same period in 2015 due to increased professional services utilized as well as costs incurred in conjunction with the relocation of our administrative functions to our Emeryville headquarters. General and administrative expenses decreased for the nine months ended September 30, 2016 as compared to the same period in 2015 primarily due to realignment of our medical affairs department from general and administrative responsibilities to research and development roles following the divestiture of our Zohydro ER business in April 2015. Also, additional professional fees were incurred during these periods during 2015 in connection with the sale of the Zohydro ER business and our stock recapitalization.

The contingent consideration liability results from our acquisition of Zogenix International Limited in October 2014 in connection with the estimated completion of certain future performance milestones related to ZX008. At each reporting period, the remaining estimated liability is determined by applying the income approach which utilizes variable inputs, such as anticipated future cash flows, risk-free adjusted discount rates, and nonperformance risk. This change is reflected in the balance of the estimated fair value of the contingent consideration (income) expense. The change in fair value of contingent consideration income for the three months ended September 30, 2016 from the same period in 2015 resulted primarily from a increase in our estimated risk-free adjusted discount rate used in the September 30, 2016 valuation from the rates used at June 30, 2016 as well as a reduction of the estimated time remaining to pay out the liability based on the passage of time from the previous period. The change in fair value of contingent consideration income for the nine months ended September 30, 2016 as compared to 2015 also resulted from a decrease in our estimated risk-free adjusted discount rate and a change in the expected timing of milestone payments from the previous December 31, 2015 and 2014 measurement dates.

Interest Expense, net. During the three and nine months ended September 30, 2016 and 2015, interest expense was incurred primarily in conjunction with our term loan with Oxford Finance LLC, or Oxford, and Silicon Valley Bank, or SVB. The change in interest expense, net for the three and nine months ended September 30, 2016 as compared to the same periods in 2015 resulted primarily from interest income generated on higher cash deposit balances subsequent to the receipt of proceeds on the sale of our Zohydro ER business in April 2015 and proceeds of our equity offering in August 2015.

Loss on Short-term Investments. We acquired shares of Pernix Therapeutics Holdings, Inc. in conjunction with our sale of the Zohydro ER business in April 2015 which were classified as short-term investments. Each reporting period, we recorded any changes in the fair value of the short-term investments as described in Note 2 to the condensed consolidated financial statements. We also evaluated our short-term investments to assess whether any unrealized loss position is other than temporarily impaired. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value had been less than the cost basis, the financial condition and near-term prospects of the issuer, and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. Based upon these factors, we determined that our short-term investments were other than temporarily impaired and adjusted their basis to the estimated fair value, which was recorded as a loss on short-term investments, during the three and nine months ended September 30, 2015. This adjusted basis was used going forward to evaluate future potential other than temporary impairment of the short-term investments. The short-term investments were subsequently sold and the remaining unrealized loss was recognized in the condensed consolidated statement of operations for the three months ended December 31, 2015.
Change in Fair Value of Warrant Liabilities. The change in fair value of warrant liabilities results from the periodic remeasurement of the estimated fair value of our warrant liabilities as discussed in Note 2 to our condensed consolidated financial statements. The expense recorded for the three months ended September 30, 2016 and three and nine months ended September 30, 2015 was primarily driven by the increase in our stock price at each reporting date as compared to the previous measurement dates. The income recorded for the nine months ended September 30, 2016 resulted from lower stock price, lower volatility and the shorter remaining term for the potential exercise of the warrants from the previous measurement date of December 31, 2015.
We expect this amount to continue to fluctuate in the near term based on changes to our stock price and other valuation inputs.
Other Expense. Other expense consists primarily of foreign currency transaction gains and losses resulting from transactions conducted in the British pound sterling and Euro.
Income Tax Benefit
We recorded a tax benefit to continuing operations of $1.0 million for the three and nine months ended September 30, 2016 related to tax rate reductions enacted in the United Kingdom in September 2016 which resulted in a decrease in our deferred tax liability.
We are required to allocate the provision for income taxes between continuing operations and other categories of earnings, such as discontinued operations. During the three and nine months ended September 30, 2016 we recognized net losses from both continuing and discontinued operations, and therefore no allocation of income tax was required. During the three and nine months ended September 30, 2015, we recognized net income from discontinued operations, and, as a result, recorded income tax expense of $2.5 million and $16.0 million, respectively, which is included in net income (loss) from discontinued operations. Accordingly, we recognized a related income tax benefit of $5.5 million and $12.4 million from continuing operations for the three and nine months ended September 30, 2015, respectively. The remaining income tax benefit to continuing operations was recognized throughout the remainder of 2015.
Discontinued Operations
On March 10, 2015, we entered into the Asset Purchase Agreement with Pernix whereby we agreed to sell our Zohydro ER business to Pernix, and on April 24, 2015, we completed the sale to Ferrimill, a subsidiary of Pernix, as a substitute purchaser. Our condensed consolidated statements of operations and comprehensive income (loss) and the condensed consolidated balance sheet reflect the financial results from the Zohydro ER business as discontinued operations for all periods presented.
For the three and nine months ended September 30, 2016 and three months ended September 30, 2015, activity reflected in the condensed consolidated statements of operations and comprehensive income (loss) consists of product delivered prior to the sale of the business for which revenue and related costs were deferred until the right of return no longer exists in accordance with our revenue recognition policy, net of adjustments, as well as legal costs incurred. Activity reflected in the condensed consolidated statements of operations and comprehensive income (loss) for the nine months ended September 30, 2015 also includes results of our commercial operations prior to the sale of the Zohydro ER business in April 2015.

Liquidity and Capital Resources
We have experienced net losses and negative cash flow from operations since inception, and as of September 30, 2016, had an accumulated deficit of $421.7 million. We expect to continue to incur net losses and negative cash flow from operating activities for at least the next year as we continue to incur costs related to the clinical development for ZX008. As of September 30, 2016, we had cash and cash equivalents of $109.9 million.
We may fund our operations through the proceeds from the sales and issuances of our common stock, if any, pursuant to the controlled equity offering program that we established on May 10, 2016 with Cantor Fitzgerald & Co., or Cantor, as sales agent, under which we may, from time to time, sell shares of common stock up to an aggregate offering price of $25.0 million. Sales of our common stock made pursuant to the controlled equity offering program, if any, will be made on the Nasdaq Global Market under our effective shelf registration statement on Form S-3. There can be no assurance that Cantor will be successful in consummating sales under the program based on prevailing market conditions or in the quantities or at the prices that we deem appropriate. Cantor or we are permitted to terminate the controlled equity offering sales agreement, or sales agreement, at any time upon 10 days' prior written notice, and Cantor is also permitted to terminate the sales agreement at any time in certain circumstances, including the occurrence of a material adverse change in our Company.
Although it is difficult to predict future liquidity requirements, we believe that our cash and cash equivalents as of September 30, 2016, along with our projected contract manufacturing revenues will be sufficient to fund our operations for at least the next twelve months. We will need to obtain additional funds to finance our operations beyond that point, or possibly earlier. We intend to raise additional capital, if necessary, through public or private equity offerings, debt financings or through collaborations or partnerships with other companies. If we are unsuccessful in raising additional required funds, we may be required to significantly delay, reduce the scope of or eliminate one or more of our development programs or our commercialization efforts, or cease operating as a going concern. We also may be required to relinquish, license or otherwise dispose of rights to product candidates or products that we would otherwise seek to develop or commercialize ourselves on terms that are less favorable than might otherwise be available.
In December 2014, we entered into a loan and security agreement, or the Loan and Security Agreement, with Oxford and SVB consisting of term loans totaling $20.0 million, and a revolving credit facility of up to $4.0 million. In June 2016, we entered into the Second Amendment to the Loan and Security Agreement, or the Second Amendment. Significant provisions of the Second Amendment include:
providing us with additional term loans in net aggregate principal amount of $3,333,334;
amending the original repayment schedule of the term loans such that we are required to make interest-only payments until February 1, 2018, then equal monthly payments of principal plus interest will be made through the maturity date of the term loans on July 1, 2020;
amending the interest rate such that the term loans bear interest at an annual rate equal to either (i) 7.00% or (ii) the sum of (a) the “prime rate” rate reported in the Wall Street Journal on the date occurring on the last business day of the month that immediately precedes the month in which the interest will accrue, plus (b) 3.25%, whichever is greater;
removing the revolving line of credit previously available under the original Loan and Security Agreement;
removing an affirmative covenant requiring us to maintain a liquidity ratio of 1.25 to 1 through our receipt of positive data from placebo-controlled trials in the United States and European Union of ZX008; and
amending a covenant to now permit us to maintain collateral account balances exceeding the greater of (i) $50,000,000, or (ii) 50% of our total collateral account balances (other than specifically excluded accounts), with financial institutions other than the lenders; provided that, if our total collateral account balances are below $50,000,000, all such balances will be maintained with the lenders.
We may prepay the outstanding principal balance of the term loan subject to a prepayment fee. The credit facility also includes events of default, as defined in the Loan and Security Agreement, which could cause interest to be charged at the rate that is otherwise applicable plus 5.0% and would provide Oxford, as collateral agent, with the right to exercise remedies against us and the collateral securing the credit facility. At September 30, 2016, we had received the original term loan proceeds of $20.0 million and additional proceeds upon executing the Second Amendment, net of loan-related fees, that are included in our cash and cash equivalents balance. The loans will be used for working capital and general business purposes.
The obligations under the Loan and Security Agreement are collateralized by our personal property (including, among other things, accounts receivable, equipment, inventory, contract rights, rights to payment of money, license agreements, general intangibles and cash), and we have agreed to not encumber any of our intellectual property. We were required to establish a controlled deposit account with SVB containing balances as outlined above which can be utilized by the lenders to satisfy the obligations in the event of default by us.

The credit facility includes affirmative and negative covenants. The affirmative covenants include, among others, covenants requiring us to maintain legal existence and governmental approvals, deliver certain financial reports, maintain insurance coverage and satisfy certain requirements regarding accounts receivable. The negative covenants include, among others, restrictions on our transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments, creating liens, selling assets and upon a change in control, in each case subject to certain exceptions.
Upon repayment of the term loan, we are also required to make a final payment equal to 6.25% of the original principal amount of the term loan funded.

Operating Activities: Net cash used for nine months ended September 30, 2016 primarily reflects the use of cash for operations, adjusted for non-cash charges including a $5.1 million change in fair value of warrant liabilities offset by $5.2 million of stock based compensation and $2.8 million change in the fair value of contingent consideration, as well as cash provided based on lower inventory balances of $2.6 million, offset by cash used of $5.1 million due to lower accounts receivable, $4.3 million related to reduction of our accounts payable and accrued expenses and $3.9 million of lower prepaid expenses and other current assets as compared to the same period in 2015. Significant working capital uses of cash for the nine months ended September 30, 2016 include personnel-related costs, research and development costs (primarily for ZX008) and other professional services, including legal and accounting services.
Net cash used for the nine months ended September 30, 2015 primarily reflects the use of cash for operations, adjusted for non-cash charges including the $89.1 million pre-tax gain on the sale of our Zohydro ER business, a $5.5 million impairment charge related to our short-term investments and a $3.5 million charge for taxes payable related to the sale of the Zohydro ER business, recognition of $7.6 million of deferred revenue and $6.0 million in stock-based compensation. Significant working capital uses of cash for the nine months ended September 30, 2015 include personnel-related costs, research and development costs (primarily for ZX008 and Relday), other professional services, including legal and accounting services, and reduction of our accounts payable and accrued expense balances totaling $11.6 million.
Investing Activities. Net cash provided by investing activities for the nine months ended September 30, 2016 was primarily attributable to the release of restricted cash from escrow in connection with the sale of our Zohydro ER business. Net cash provided by investing activities for the nine months ended September 30, 2015 was primarily attributable to the proceeds from the sale of our Zohydro ER business.
Financing Activities. Net cash used in financing activities for the nine months ended September 30, 2016 represents principal payments made on our term loan and proceeds from stock purchases made in accordance with our employee stock purchase plan during the period, offset by proceeds from our amended term loan with Oxford and SVB. Net cash provided by financing activities for the nine months ended September 30, 2015 consists of net proceeds from our public equity offering of $92.0 million and $1.4 million from the exercise of stock options and the issuance of common stock under our employee stock purchase plan, offset by the repayment of our revolving credit facility advance of $1.4 million.
Successful transition to profitability is dependent upon achieving a level of product revenues adequate to support our cost structure. We will continue to monitor and evaluate the level of our research, development, contract manufacturing and operating expenditures and may adjust such expenditures based upon a variety of factors, such as our available cash, our ability to obtain additional cash, the results and progress in our clinical programs, the time and costs related to clinical trials and regulatory decisions, as well as the U.S. economic environment.

We cannot be certain if, when and to what extent we will generate positive cash flow from operations from the commercialization of our product candidates, if approved. We expect our expenses to be substantial and to increase over the next few years as we continue to advance ZX008 and Relday through clinical development.
Off-Balance Sheet Arrangements
We have not engaged in any off-balance sheet activities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk
Interest Rate Risk
Our cash and cash equivalents as of September 30, 2016 consisted of cash and money market funds. The primary objective of our investment activities is to preserve principal. Instruments that meet this objective include commercial paper, money market funds and government and non-government debt securities. To minimize this risk, we intend to continue to maintain our portfolio of cash and money market funds, and due to their short-term nature, we believe that there is no material exposure to interest rate risk.
Our term loan with Oxford and SVB contain adjustable rate interest terms. The loan bears interest at an annual rate equal to the greater of (i) 7.00% and (ii) the sum of (a) the “prime rate” rate reported in the Wall Street Journal on the date occurring on the last business day of the month that immediately precedes the month in which the interest will accrue, plus (b) 3.25%. Based on our outstanding principal balances and historical interest rate volatility, we do not believe an adjustment of 100 basis points would create a material exposure.

Item 4. Controls and Procedures
Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the timelines specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As required by Securities and Exchange Commission Rule 13a-15(b), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2016 at the reasonable assurance level.
Changes in Disclosure Controls and Procedures
There were no changes in our internal control over financial reporting during the fiscal quarter ended September 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors
There have been no material changes to the risk factors included in “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, other than those set forth below, which should be read in conjunction with the risk factors disclosed therein.

Risks Related to Our Business and Industry

Delays in the commencement or completion of clinical testing for ZX008, Relday or pre-clinical or clinical testing for any of our other product candidates could result in increased costs to us and delay or limit our ability to pursue regulatory approval for, or generate revenues from, such product candidates.
Clinical trials are very expensive, time consuming and difficult to design and implement. Delays in the commencement or completion of clinical testing for ZX008, Relday or pre-clinical or clinical testing for any of our other product candidates could significantly affect our product development costs and business plan.
The safety and effectiveness of ZX008 has been evaluated in a single, continuing, long-term, open-label, study in patients with Dravet syndrome in Belgium. In January 2016, we initiated a Phase 3 clinical trial in North America for ZX008 as an adjunctive treatment of seizures in children with Dravet syndrome. This followed FDA acceptance of our investigational new drug, or IND, application for ZX008 in December 2015. The Phase 3 program for ZX008 includes two randomized, double-blind placebo-controlled studies that will evaluate two dose levels of ZX008 (0.2 mg/kg/day and 0.8 mg/kg/day, up to a maximum daily dose of 30 mg), as well as placebo. We intend to enroll 105 subjects in each of the two studies, with 35 patients in each treatment arm. The first study is being conducted in North America. The other Phase 3 study is a multi-national study, conducted primarily in western Europe, which commenced in June 2016. In addition, a one-year, open-label safety study will be offered to eligible subjects who complete one of these trials. We expect to receive top-line results from each of these trials in the second quarter of 2017. Additionally, we initiated enrollment of patients in our European study of Dravet syndrome patients who are poor responders to a stiripentol treatment regime in the third quarter of this year. However, we may not be able to identify and enroll sufficient study participants and interpret results on these timeframes, and consequently the completion of our Phase 3 clinical trials may be delayed.
We initiated clinical testing for Relday in patients with schizophrenia in July 2012 and announced positive single-dose pharmacokinetic results from the Phase 1 clinical trial in January 2013. Based on the favorable safety and pharmacokinetic profile demonstrated in the Phase 1 trial, we extended the study to include an additional dose of the same formulation and announced positive top-line results in May 2013. The results for the extended Phase 1 clinical trial showed risperidone blood concentrations in the assumed therapeutic range were achieved on the first day of dosing and maintained throughout the one-month period. In addition, dose proportionality was demonstrated across the full dose range studied. In March 2015, we began a multi-dose clinical trial, which we believe will provide the required steady-state pharmacokinetic and safety data prior to initiating Phase 3 development studies. On September 30, 2015, we announced positive top-line pharmacokinetic results from our Phase 1b multi-dose clinical trial of Relday. Based on this data, we have initiated efforts to secure a global strategic development and commercialization partner for Relday to support the continued development of Relday. If we are unable to secure such a partner on favorable terms, or at all, we will evaluate the continued development of Relday.
The commencement and completion of clinical trials can be delayed for a number of reasons, including delays related to:
obtaining regulatory authorization to commence a clinical trial;
reaching agreement on acceptable terms with clinical research organizations, or CROs, clinical investigators and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs, clinical investigators and trial sites;
manufacturing or obtaining sufficient quantities of a product candidate and placebo for use in clinical trials;
obtaining institutional review board, or IRB, approval to initiate and conduct a clinical trial at a prospective site;
identifying, recruiting and training suitable clinical investigators;

28

Table of Contents

identifying, recruiting and enrolling subjects to participate in clinical trials for a variety of reasons, including competition from other clinical trial programs for the treatment of similar indications;
retaining patients who have initiated a clinical trial but may be prone to withdraw due to side effects from the therapy, lack of efficacy, personal issues or for any other reason they choose, or who are lost to further follow-up;
uncertainty regarding proper dosing; and
scheduling conflicts with participating clinicians and clinical institutions.
In addition, if a significant number of patients fail to stay enrolled in any of our current or future clinical trials of ZX008, Relday or any of our other product candidates and such failure is not adequately accounted for in our trial design and enrollment assumptions, our clinical development program could be delayed. Clinical trials may also be delayed or repeated as a result of ambiguous or negative interim results or unforeseen complications in testing. In addition, a clinical trial may be suspended or terminated by us, the FDA or EMA, the IRB overseeing the clinical trial at issue, any of our clinical trial sites with respect to that site, or other regulatory authorities due to a number of factors, including:
inability to design appropriate clinical trial protocols;
inability by us, our employees, our CROs or their employees to conduct the clinical trial in accordance with all applicable FDA, drug enforcement administration, or DEA, or other regulatory requirements or our clinical protocols;
inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;
discovery of serious or unexpected toxicities or side effects experienced by study participants or other unforeseen safety issues;
lack of adequate funding to continue the clinical trial, including the incurrence of unforeseen costs due to enrollment delays, requirements to conduct additional trials and studies and increased expenses associated with the services of our CROs and other third parties;
lack of effectiveness of any product candidate during clinical trials;
slower than expected rates of subject recruitment and enrollment rates in clinical trials;
inability of our CROs or other third-party contractors to comply with all contractual requirements or to perform their services in a timely or acceptable manner;
inability or unwillingness of medical investigators to follow our clinical protocols; and
unfavorable results from on-going clinical trials and pre-clinical studies.
Additionally, changes in applicable regulatory requirements and guidance may occur and we may need to amend clinical trial protocols to reflect these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for reexamination, which may impact the costs, timing or successful completion of a clinical trial. If we experience delays in the completion of, or if we terminate, any of our clinical trials, the commercial prospects for ZX008, Relday and our other product candidates may be harmed, which may have a material adverse effect on our business, results of operations, financial condition and prospects.

We face intense competition, and if our competitors market and/or develop treatments for Dravet syndrome or psychiatric disorders that are marketed more effectively, approved more quickly than our product candidates or demonstrated to be safer or more effective than our products, our commercial opportunities will be reduced or eliminated.
The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary therapeutics. We face competition from a number of sources, some of which may target the same indications as our products or product candidates, including large pharmaceutical companies, smaller pharmaceutical companies, biotechnology companies, academic institutions, government agencies and private and public research institutions, many of which have greater financial resources, sales and marketing capabilities, including larger, well-established sales forces, manufacturing capabilities, experience in obtaining regulatory approvals for product candidates and other resources than we do.
If approved for the chronic treatment of Dravet syndrome, ZX008 may compete against other products and product candidates. In the European Union, Canada and Japan, Diacomit (stiripentol) by Laboratoires Biocodex has been approved and is being commercialized as an adjunctive therapy (in combination with sodium valproate and clobazam) for the treatment of Dravet syndrome; stiripentol, while not yet approved by FDA, is available to patients in the United States via the FDA’s Personal Importation Policy. Epidiolex®, a cannabinoid drug, which is being developed by GW Pharmaceuticals, has received an orphan designation by the EMA for the treatment of Dravet syndrome and by the FDA for the treatment of Dravet and Lennox-Gastaut syndromes, as well as fast track status by the FDA for the treatment of Dravet syndrome. In March 2016, GW Pharmaceuticals announced positive results from its first Phase 3 clinical trial for Epidiolex for the treatment of Dravet syndrome, and in June and September 2016 announced positive results from its two Phase 3 clinical trials for Epidiolex for the

29

Table of Contents

treatment of Lennox-Gastaut syndromes, with the drug achieving its primary study endpoints in all three trials. GW Pharmaceuticals is currently conducting an additional Phase 3 study in Dravet syndrome and has announced they intend to file an NDA for both indications in 2017. Insys Therapeutics has advanced its pharmaceutical cannabinoid program, which has received orphan drug designation and fast track status by the FDA for use of cannabidiol as a potential treatment for Dravet syndrome. Sage Therapeutics has completed a Phase 1/2 clinical trial for its lead compound SAGE-547, an allosteric modulator of GABA receptors, for the acute treatment of super-refractory status epilepticus, which are acute prolonged seizures that can be associated with Dravet syndrome, as well as other seizure conditions.
If approved for the treatment of schizophrenia, we anticipate that Relday will compete against other marketed, branded and generic, typical and atypical antipsychotics, including both long-acting injectable and oral products. Currently marketed long-acting injectable atypical antipsychotic products include Risperdal Consta, Invega Sustenna and Invega Trinza marketed by Janssen Pharmaceuticals, Zyprexa Relprevv marketed by Eli Lilly & Company, Aristada marketed by Alkermes plc and Abilify Maintena (apripiprazole) marketed by Otsuka Pharmaceutical Co., Ltd. and H. Lundbeck A/S. Currently approved and marketed oral atypical antipsychotics include Risperdal (risperidone) and Invega (paliperidone) marketed by Janssen Pharmaceuticals, generic risperidone, Zyprexa (olanzapine) marketed by Eli Lilly and Company, Seroquel (quetiapine) marketed by AstraZeneca plc, Abilify (aripiprazole) marketed by BMS/Otsuka Pharmaceutical Co., Ltd., Geodon (ziprasidone) marketed by Pfizer, Fanapt (iloperidone) marketed by Vanda Pharmaceuticals, Inc., Saphris (asenapine) marketed by Merck & Co., Latuda (lurasidone) marketed by Dainippon Sumitomo Pharma and generic clozapine. Finally, in addition to these currently marketed products, we may also face competition from additional long-acting injectable product candidates that could be developed by the large companies listed above, as well and by other pharmaceutical companies such as Teva, Braeburn Pharmaceuticals, Laboratorios Farmaceuticos Rovi SA, Indivior PLC and Luye Pharma Group, Ltd., each of which has announced they are developing long-acting antipsychotic product candidates. In May 2015, Janssen Pharmaceuticals announced that the FDA approved Invega Trinza, a three-month long-version of paliperidone palmitate, for the treatment of schizophrenia in patients adequately treated with Invega Sustenna for at least four months. Also in May 2015, Indivior PLC announced positive top-line results from its Phase 3 clinical trial of RBP-7000, an investigational drug formulation of risperidone for the treatment of schizophrenia that is intended to require once-monthly dosing. In October 2015, Alkermes plc announced that the FDA approved Aristada (aripiprazole lauroxil) extended-release injectable suspension for the treatment of schizophrenia, which offers once-monthly and six-week dosing options.
We expect ZX008, Relday and any of our other product candidates, if approved, to compete on the basis of, among other things, product efficacy and safety, time to market, price, coverage and reimbursement by third-party payors, extent of adverse side effects and convenience of treatment procedures. One or more of our competitors may develop other products that compete with ours, obtain necessary approvals for such products from the FDA, or other agencies, if required, more rapidly than we do or develop alternative products or therapies that are safer, more effective and/or more cost effective than any products developed by us. The competition that we will encounter with respect to any of our product candidates that receive the requisite regulatory approval and classification and are marketed will have an effect on our product prices, market share and results of operations. We may not be able to differentiate any products that we are able to market from those of our competitors, successfully develop or introduce new products that are less costly or offer better results than those of our competitors or offer purchasers of our products payment and other commercial terms as favorable as those offered by our competitors. In addition, competitors may seek to develop alternative formulations of our product candidates and/or alternative drug delivery technologies that address our targeted indications.
The commercial opportunity for our product candidates could be significantly harmed if competitors are able to develop alternative formulations and/or drug delivery technologies outside the scope of our products. Compared to us, many of our potential competitors have substantially greater:

capital resources;
research and development resources and experience, including personnel and technology;
drug development, clinical trial and regulatory resources and experience;
sales and marketing resources and experience;
manufacturing and distribution resources and experience;
name recognition; and
resources, experience and expertise in prosecution and enforcement of intellectual property rights.
 
As a result of these factors, our competitors may obtain regulatory approval of their products more rapidly than we are able to or may obtain patent protection or other intellectual property rights that limit or block us from developing or commercializing our product candidates. Our competitors may also develop drugs that are more effective, more useful, better tolerated, subject to fewer or less severe side effects, more widely prescribed or accepted or less costly than ours and may also be more successful than we are in manufacturing and marketing their products. If we are unable to compete effectively with the marketed therapeutics of our competitors or if such competitors are successful in developing products that compete with any of our product candidates that are approved, our business, results of operations, financial condition and prospects may be materially adversely affected.

We may engage in strategic transactions that could impact our liquidity, increase our expenses and present significant distractions to our management.

From time to time we may consider strategic transactions, such as acquisitions of companies, asset purchases and out-licensing or in-licensing of products, product candidates or technologies. For example, in October 2014, we completed the acquisition of Brabant, which owns worldwide development and commercialization rights to ZX008 for the treatment of Dravet syndrome, and in October 2016, we completed an asset purchase agreement to acquire the global rights to a preclinical development program for orphan CNS disorders. Additional potential transactions that we may consider include a variety of different business arrangements, including spin-offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any such transaction may require us to incur non-recurring or other charges, may increase our near and long-term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our operations and financial results. For example, these transactions may entail numerous operational and financial risks, including:
exposure to unknown liabilities;
disruption of our business and diversion of our management’s time and attention in order to develop acquired products, product candidates or technologies;
incurrence of substantial debt or dilutive issuances of equity securities to pay for acquisitions;
higher than expected acquisition and integration costs;
write-downs of assets or goodwill or impairment charges;
increased amortization expenses;
difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;
impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
inability to retain key employees of any acquired businesses.

Accordingly, although there can be no assurance that we will undertake or successfully complete any additional transactions of the nature described above, any additional transactions that we do complete could have a material adverse effect on our business, results of operations, financial condition and prospects.
We may not realize the full economic benefit from the sale of our Sumavel DosePro business and Zohydro ER business.    
Pursuant to the asset purchase agreement with Endo that we entered into in April 2014, or the Endo asset purchase agreement, in addition to the $89.6 million upfront cash payment, we may receive contingent payments, based on Endo’s achievement of pre-determined sales and gross margin milestones, in an amount up to $20.0 million. Our ability to receive these contingent payments under our supply agreement with Endo is dependent upon Endo successfully maintaining and increasing market demand for, and sales of, Sumavel DosePro.
Pursuant to the Asset Purchase Agreement with Pernix that we entered into in March 2015, we may receive contingent payments of up to $283.5 million, based on Pernix’s achievement of pre-determined milestones. These milestones include a $12.5 million payment upon approval by the FDA of an abuse-deterrent extended-release hydrocodone tablet and up to $271.0 million in potential sales milestones. Our ability to receive these contingent payments is dependent upon Pernix successfully maintaining and increasing market demand for, and sales of, Zohydro ER in a manner in which the requisite sales of the product will be achieved and devoting the resources necessary to achieve the manufacturing milestone.
We cannot provide any assurance that we will receive any of the contingent milestone payments.

Fluctuations in the value of the Euro or U.K. pound sterling could negatively impact our results of operations and increase our costs.

WE conduct research and development activities in the United Kingdom and some of the payments for these activities are denominated in Euros and U.K. pounds sterling. As a result, we are exposed to foreign exchange risk, and our results of operations may be impacted by fluctuations in the exchange rate between the U.S. dollar and the Euro or U.K. pound sterling, such as the decline in value of the U.K. pound sterling following the results of the United Kingdom’s referendum on withdrawal from the European Union. A significant appreciation in the Euro or U.K. pound sterling relative to the U.S. dollar will result in higher expenses and cause increases in our net losses. Likewise, to the extent that we generate any revenues denominated in foreign currencies, or become required to make payments in other foreign currencies, fluctuations in the exchange rate between the U.S. dollar and those foreign currencies could also negatively impact our results of operations. We currently have not entered into any foreign currency hedging contracts to reduce the effect of changes in foreign currency exchange rates, and foreign currency hedging is inherently risky and may result in unanticipated losses.

The results of the United Kingdom’s referendum on withdrawal from the European Union may have a negative effect on global economic conditions, financial markets and our business.
We are a company with worldwide operations, which includes significant business operations in Europe, and our wholly owned subsidiary Zogenix Europe Limited is incorporated under the laws of England and Wales. In June 2016, a majority of voters in the United Kingdom elected to withdraw from the European Union in a national referendum. The referendum was advisory, and the terms of any withdrawal are subject to a negotiation period that could last at least two years after the government of the United Kingdom formally initiates a withdrawal process. Nevertheless, the referendum has created significant uncertainty about the future relationship between the United Kingdom and the European Union, and has given rise to calls for certain regions within the United Kingdom to preserve their place in the European Union by separating from the United Kingdom as well as for the governments of other EU member states to consider withdrawal.
These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and could significantly reduce global market liquidity and restrict the ability of key market participants to operate in certain financial markets. Asset valuations, currency exchange rates and credit ratings may be especially subject to increased market volatility. Lack of clarity about future U.K. laws and regulations as the United Kingdom determines which EU laws to replace or replicate in the event of a withdrawal, including financial laws and regulations, tax and free trade agreements, intellectual property rights, supply chain logistics, environmental, health and safety laws and regulations, immigration laws and employment laws, could decrease foreign direct investment in the United Kingdom, increase costs, depress economic activity and restrict our access to capital. If the United Kingdom and the European Union are unable to negotiate acceptable withdrawal terms or if other EU member states pursue withdrawal, barrier-free access between the United Kingdom and other EU member states or among the European economic area overall could be diminished or eliminated. Any of these factors could have a material adverse effect on our business, financial condition and results of operations and affect our strategy in the European pharmaceutical market.
Risks Related to Our Financial Position and Capital Requirements

The terms of our credit facility place restrictions on our operating and financial flexibility.
We have entered into a loan and security agreement, or the credit facility, with Oxford Finance LLC, or Oxford, as collateral agent, and the lenders party thereto from time to time, or the lenders, including Oxford and Silicon Valley Bank, or SVB, that is secured by substantially all of our personal property other than our intellectual property. The outstanding principal balance under the credit facility was $20.0 million at September 30, 2016.
The credit facility includes affirmative and negative covenants applicable to us and any subsidiaries we create in the future. The affirmative covenants include, among others, covenants requiring us to maintain our legal existence and governmental approvals, deliver certain financial reports, maintain insurance coverage and satisfy certain requirements regarding accounts receivable. The negative covenants include, among others, restrictions on our transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments, creating liens, selling assets and undergoing a change in control, in each case subject to certain exceptions.
The credit facility also includes events of default, the occurrence and continuation of which could cause interest to be charged at the rate that is otherwise applicable plus 5.0% and would provide Oxford, as collateral agent, with the right to exercise remedies against us and the collateral securing the credit facility, including foreclosure against our properties securing the credit facilities, including our cash. These events of default include, among other things, our failure to pay any amounts due under the credit facility, a breach of covenants under the credit facility, our insolvency, a material adverse change, the

occurrence of any default under certain other indebtedness in an amount greater than $400,000 and one or more judgments against us in an amount greater than $400,000, individually or in the aggregate.
Our ability to make scheduled payments on or to refinance our indebtedness depends on our future performance and ability to raise additional sources of cash, which is subject to economic, financial, competitive and other factors beyond our control. If we are unable to generate sufficient cash to service our debt, we may be required to adopt one or more alternatives, such as selling assets, restructuring our debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. If we desire to refinance our indebtedness, our ability to do so will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.
Risks Related to Regulation of our Product and Product Candidates
Our product candidates are subject to extensive regulation, and we cannot give any assurance that any of our product candidates will receive regulatory approval or be successfully commercialized.
We currently are developing ZX008 for the treatment of seizures associated with Dravet syndrome and Relday for the treatment of the symptoms of schizophrenia. The research, testing, manufacturing, labeling, approval, sale, marketing and distribution of drug products, among other things, are subject to extensive regulation by the FDA and other regulatory authorities in the United States. We are not permitted to market ZX008, Relday or any of our other product candidates in the United States unless and until we receive regulatory approval from the FDA. We cannot provide any assurance that we will obtain regulatory approval for any of our product candidates or that any such product candidates will be successfully commercialized.
Under the policies agreed to by the FDA under the Prescription Drug User Fee Act, or PDUFA, the FDA is subject to a two-tiered system of review times for new drugs: standard review and priority review. For drugs subject to standard review that do not contain a new molecular entity, such as Relday, the FDA has a goal to complete its review of the NDA and respond to the applicant within ten months from the date of receipt of an NDA. The review process and the PDUFA target action date may be extended if the FDA requests or the NDA sponsor otherwise provides additional information or clarification regarding information already provided in the submission. The FDA's review goals are subject to change, and the duration of the FDA's review may depend on the number and type of other NDAs that are submitted to the FDA around the same time period.
The FDA may also refer applications for novel products or products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved. Although the FDA is not bound by the recommendation of an advisory committee, the matters discussed at the advisory committee meeting, and in particular any concerns regarding safety, could limit our ability to successfully commercialize our product candidates subject to advisory committee review.
As part of its review of an NDA, the FDA may inspect the facility or facilities where the drug is manufactured. If the FDA's evaluations of the NDA and the clinical and manufacturing procedures and facilities are favorable, the FDA will issue an action letter, which will be either an approval letter, authorizing commercial marketing of the drug for a specified indication, or a Complete Response Letter containing the conditions that must be met in order to secure approval of the NDA. These conditions may include deficiencies identified in connection with the FDA's evaluation of the NDA submission or the clinical and manufacturing procedures and facilities. Until any such conditions or deficiencies have been resolved, the FDA may refuse to approve the NDA. If and when those conditions have been met to the FDA's satisfaction, the FDA will issue an approval letter. The FDA has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons. For example:
the FDA may not deem a product candidate safe and effective;
the FDA may not find the data from pre-clinical studies and clinical trials sufficient to support approval;
the FDA may require additional pre-clinical studies or clinical trials;
the FDA may not approve of our third-party manufacturers' processes and facilities; or
the FDA may change its approval policies or adopt new regulations.
Product candidates such as ZX008 and Relday, and any of our other product candidates, may not be approved even if they achieve their specified endpoints in clinical trials. The FDA may disagree with our trial design and our interpretation of data from clinical trials, or may change the requirements for approval even after it has reviewed and commented on the design for our clinical trials. The FDA may also approve a product candidate for fewer or more limited indications than we request or may grant approval contingent on the performance of costly post-approval clinical trials. In addition, the FDA may not approve the labeling claims that we believe are necessary or desirable for the successful commercialization of our product candidates. Approval may be contingent on a risk evaluation and mitigation strategy, or REMS program, which limits the labeling, distribution or promotion of a drug product.

ZX008, Relday and any of our other product candidates may not achieve their specified endpoints in clinical trials. The safety and effectiveness of ZX008 has been evaluated in a continuing, long-term, open-label, study in patients with Dravet syndrome at a single academic medical institution in Belgium. In January 2016 we initiated a Phase 3 clinical trial in the United States for ZX008 as an adjunctive treatment of seizures in children with Dravet syndrome. This study initiation followed FDA acceptance of our investigational new drug, or IND, application for ZX008 in December 2015. The Phase 3 program for ZX008 includes two randomized, double-blind placebo-controlled studies that will include two dose levels of ZX008 (0.2 mg/kg/day and 0.8 mg/kg/day, up to a maximum daily dose of 30 mg), as well as placebo. We intend to enroll 105 subjects in each of the two studies, with 35 patients in each treatment arm. The first study will be conducted in North America. The other study will be a multi-national study, conducted primarily in western Europe which commenced in June 2016. The primary endpoint of both trials is the change in frequency of convulsive seizures as compared to placebo. The key secondary endpoints include 40% and 50% responder analyses, which are important for European regulatory submissions, and the convulsive seizure free interval, which is of significant interest to parents and to patients. In addition, a one-year, open-label safety study will be offered to eligible subjects who complete one of these trials. We expect to receive top-line results from each of these trials in the second quarter of 2017. Additionally, we intend to initiate the enrollment of patients in our European study of Dravet syndrome patients who are poor responders to a stiripentol treatment regime in the fourth quarter of this year. However, we may not be able to identify and enroll sufficient study participants and interpret results on these timeframes, and consequently the completion of our Phase 3 clinical trials may be delayed.
We initiated a Phase 1 safety and pharmacokinetic clinical trial for Relday in July 2012 and announced positive single-dose pharmacokinetic results from this trial in January 2013. Based on the favorable safety and pharmacokinetic profile demonstrated with the 25 mg and 50 mg once-monthly doses tested in the Phase 1 trial, we extended the study to include an additional cohort of ten patients at a 100 mg dose of the same formulation and announced positive top-line results from the extended Phase 1 clinical trial in May 2013. The positive results from this study extension positioned us to begin a multi-dose clinical trial, which will provide the required steady-state pharmacokinetic and safety data prior to initiating Phase 3 development studies. We started this multi-dose clinical trial in the first half of 2015, and we announced positive top-line pharmacokinetic data in September 2015. Based on this data, we have initiated efforts to secure a global strategic development and commercialization partner for Relday to support the continued development of Relday. If we are unable to secure such a partner on favorable terms, or at all, we will evaluate the continued development of Relday.
If we are unable to obtain regulatory approval for ZX008, Relday or any other product candidates on the timeline we anticipate, we may not be able to execute our business strategy effectively and our ability to generate revenues may be limited.
