Supernus Pharmaceuticals, Inc.
Notes to Condensed Consolidated Financial Statements (unaudited)
1.
Organization and Business
Supernus Pharmaceuticals, Inc. (the Company) was incorporated in Delaware and commenced operations in 2005. The Company is a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases. The Company markets two products: Oxtellar XR for the treatment of epilepsy, and Trokendi XR for the prophylaxis of migraine headache and treatment of epilepsy. The Company has several proprietary product candidates in clinical development that address opportunities in the CNS market.
The Company launched Oxtellar XR and Trokendi XR for the treatment of epilepsy in 2013, launched Trokendi XR for the prophylaxis of migraine headache in adolescents and adults in April 2017, and launched Oxtellar XR with an expanded indication to include monotherapy for partial seizures in January 2019.
2.
Summary of Significant Accounting Policies
Basis of Presentation
The Company’s condensed consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc., Supernus Europe Ltd., Biscayne Neurotherapeutics, Inc. and its wholly-owned subsidiary, Biscayne Neurotherapeutics Australia Pty Ltd., collectively referred to herein as “Supernus” or “the Company.” All significant intercompany transactions and balances have been eliminated in consolidation.
The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (SEC) for interim financial information. As permitted under Generally Accepted Accounting Principles in the United States (U.S. GAAP), certain notes and other information have been omitted from the interim unaudited condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these financial statements should be read in conjunction with the Company’s most recent Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC.
In management’s opinion, the condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows. The results of operations for any interim period are not necessarily indicative of the Company’s future quarterly or annual results.
The Company, which is primarily located in the United States (U.S.), operates in one operating segment.
Use of Estimates
The Company bases its estimates on: historical experience; various forecasts; information received from its service providers; and other assumptions that the Company believes are reasonable under the circumstances. Actual results could differ materially from the Company’s estimates. The Company evaluates the methodologies employed in its estimates on an ongoing basis.
Revenue Recognition
The Company recognizes revenue when physical control of goods or provision of services are transferred to the Company’s customers in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The Company does not adjust revenue for any financing effects in transactions where the Company expects the period between the transfer of the goods or services and collection to be less than one year.
There were no contract assets or liabilities recorded as of September 30, 2019.
Revenue from Product Sales
The Company’s customers, who are primarily pharmaceutical wholesalers and distributors, purchase product to fulfill orders from retail pharmacy chains and independent pharmacies of varying size and purchasing power. The Company recognizes gross revenue when its products are physically received by its customers after shipment from a third party fulfillment center. Customers take control of the products, including title and ownership, upon physical receipt of our products at the customers' facilities.

Table of Contents


Product sales are recorded net of various forms of variable consideration, including: estimated liability for rebates; an estimated liability for future product returns; and an estimated allowance for discounts. These are collectively considered "sales deductions."
As described below, variability in the net transaction price for the Company’s products arises primarily from sales deductions and significant judgment is required in estimating sales deductions. In making these estimates, the Company considers: historical experience; product price increases; current contract prices under applicable programs; unbilled claims; processing time lags; and inventory levels in the distribution channel. The Company adjusts its estimates of revenue either when the most likely amount of consideration it expects to receive changes, or when the consideration becomes fixed.
If actual results in the future vary from the estimates, the Company adjusts these estimates. These adjustments could materially affect net product sales and earnings in the period that such adjustments are recorded.
Sales Deductions
The Company records product sales net of the following sales deductions:
Rebates:  Rebates are discounts which the Company pays under either public sector or private sector health care programs. Public sector rebate programs encompass: various Medicaid drug rebate programs; Medicare coverage gap programs; and programs covering public health service institutions and government entities. All federal employees and agencies purchase drugs under the Federal Supply Schedule. Private sector rebate programs include: contractual agreements with managed care providers, under which the Company pays fees to gain access to that provider’s patient drug formulary; and Company sponsored programs, under which the Company defrays or eliminates patient co-payment charges that the patient would otherwise pay to their managed care provider.
Rebates paid under public sector programs are generally mandated under law, whereas private sector rebates are generally contractually negotiated by the Company with managed care providers.
Rebates are owed upon dispensing our product to a patient; i.e., filling a prescription. The accrual balance for rebates consists of three components. First, because rebates are generally invoiced and paid quarterly in arrears, the accrual balance consists of an estimate of the amount expected to be incurred for prescriptions dispensed in the current quarter. Second, the accrual balance also includes an estimate for known or estimated prior quarters’ unpaid rebates, to cover prescriptions dispensed in past quarters, but for which no invoice has been received. Third, the accrual balance includes an estimate for rebates that will be prospectively owed, for prescriptions filled in future quarters. This pertains to product that has been sold to wholesalers or distributors, and which resides either as wholesaler/distributor inventory, or as inventory held at pharmacies.
The Company’s estimates of expected rebate claims vary by program and by type of customer, because the period from the date at which the prescription is filled to the date the Company receives and pays the invoice varies substantially. For each of its products, the Company bases its estimates of expected rebate claims on multiple factors, including historical levels of deductions; contractual terms with managed care providers; actual and anticipated changes in product price; prospective changes in managed care fee for service contracts; prospective changes in co-pay assistance programs; and anticipated changes in program utilization rates (i.e., patient participation rates under a specific program). The Company records an estimated liability for rebates at the time the customer takes title to the product (i.e., at the time of sale to wholesalers/distributors), and records this liability as a reduction to gross product sales and an increase in Accrued product returns and rebates in current liabilities on its condensed consolidated balance sheets.
The sensitivity of the Company’s estimates varies by program and by type of customer. If actual rebates vary from estimated amounts, the Company will adjust the balances of such accrued rebates to reflect actual experience with respect to these programs. These changes could materially affect the estimated liability balance, net product sales and earnings in the period of adjustment.
Returns:  Sale of the Company’s products are not subject to a general right of return. However, the Company will accept return of product that is damaged or defective when shipped from its third party fulfillment center. In addition, the Company will accept return of expired product six months prior to and up to 12 months subsequent to the product’s expiry date. Expired or defective returned product cannot be re-sold and is therefore destroyed. Product that has been used to fill patient prescriptions is no longer subject to any right of return.
The Company records an estimated liability for product returns at the time the customer takes title to the product (i.e., at time of sale) as a reduction to gross product sales and an increase in Accrued product returns and rebates

in current liabilities on the condensed consolidated balance sheets. The Company estimates the liability for returns based on the actual returns experience for its two commercial products, in conjunction with industry experience for return of similar products (i.e., ambient temperature storage for oral formulations). Because the Company’s products have not reached maturity, the return rate of its products has and is expected to continue to vary.
The Company’s products have a shelf life of 48 months from date of manufacture. Because of the extended shelf life, coupled with its return policy, there typically is a significant time lag between the time at which the product is sold and when the Company issues credit on expired product. Because the Company’s policy generally permits product returns to be processed at current wholesaler price rather than historical acquisition price, the Company’s estimated liability for product returns is affected by price increases taken subsequent to the date of sale. Therefore, price increase(s) taken during the current period increase(s) the liability for product returns because they affect the estimated liability for product returns for both sales made in the current period as well as sales made in prior periods.
When the Company adjusts its estimates for product returns, either favorably or unfavorably, this adjustment affects the estimated liability, product sales and earnings in the period of adjustment.
Sales discounts:  Distributors and wholesalers of the Company's pharmaceutical products are generally offered various forms of consideration, including allowances, service fees and prompt payment discounts for distributing our products. Distributor and wholesaler allowances and service fees arise from contractual agreements and are estimated as a percentage of the price at which the Company sells product to them. In addition, distributor and wholesaler are offered a prompt pay discount for payment within a specified period.
The Company accounts for these discounts at the time of sale, as a reduction to gross product sales, and records these amounts as a valuation allowance against Accounts receivable on the condensed consolidated balance sheets.
Customer orders are generally fulfilled within a few days of receipt, resulting in minimal order backlog. There are no minimum product purchase requirements.
License Revenues
License and Collaboration Agreements
The Company has entered into collaboration agreements to commercialize both Oxtellar XR and Trokendi XR outside of the U.S., which agreements include the right to use the Company’s intellectual property as a functional license. These agreements generally include an up-front license fee and ongoing milestone payments upon the achievement of specific events. These agreements may also require minimum royalty payments, based on sales of products developed from the applicable intellectual property.
Up-front license fees are recognized once the license has been executed between the Company and its licensee.
Milestones are a form of variable consideration that are recognized when either the underlying events have transpired (i.e., event-based milestone) or when the sales-based targets have been met by the collaborative partner (i.e., sales-based milestone). Both types of milestone payments are nonrefundable. The Company evaluates whether achieving the milestone is considered probable and estimates the amount of the milestone to be included in the transaction price using the most likely amount method. The value of the associated milestone is not included in the transaction price if it is probable that a significant revenue reversal would occur. This estimation is based on management’s judgment, including assessing factors that are outside of the Company’s influence, such as: likelihood of regulatory success; availability of third party information; and expected time period until achievement of the event. These factors are evaluated based on the specific facts and circumstances.
Event-based milestones are recognized in the period that the related event, such as regulatory approval, occurs. Milestone payments that are not within the control of the Company, such as approval from regulatory authorities, or where attainment of the specified event is dependent on the success of a third-party are not considered probable until the specified event occurs. Sales-based milestones are recognized as revenue only when the sales-based target is achieved. Revenue is recognized from the satisfaction of performance obligations in the amount billable to the customer.
No guaranteed minimum amounts are owed to the Company related to license and collaboration agreements.

Royalty Revenues
The Company recognizes noncash royalty revenue for amounts earned pursuant to a royalty agreement with United Therapeutics Corporation (United Therapeutics), which agreement includes the right to use the Company’s intellectual property as a functional license. In 2014, the Company sold certain of these royalty rights to Healthcare Royalty Partners III, L.P. (HC Royalty) (see Note 17, Commitments and Contingencies). Accordingly, the Company records noncash royalty revenue based on estimated product sales by United Therapeutics, in which sales of United Therapeutics' product results in payments made from United Therapeutics to HC Royalty in connection with these agreements.
Royalty revenue also includes royalty amounts received from collaboration partners, including from Shire Plc (Shire, a subsidiary of Takeda Pharmaceutical Company Ltd), based on net product sales of Shire’s product, Mydayis, in the current period. Royalty revenue is only recognized when the underlying product sale by Shire occurs. The Shire arrangement also includes Shire's right to use the Company’s intellectual property as a functional license.
There are no guaranteed minimum amounts owed to the Company related to any royalty revenue agreement.
Research and Development Expense
Research and development expenditures are expensed as incurred. These expenses include: salaries, benefits and share-based compensation; contract research and development services provided by third parties; costs for preclinical and clinical studies; the cost of acquiring or manufacturing clinical trial material; regulatory costs; facilities costs; depreciation expense and other allocated expenses; and license fees and milestone payments related to in-licensed products and technologies. Assets acquired that are used for research and development and that have no future alternative use are expensed as in-process research and development.
Preclinical Study and Clinical Trial Accruals
The Company estimates preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research institutions, clinical investigators, clinical research organizations (CROs) and other service providers that conduct activities on the Company’s behalf. In recording service fees, the Company estimates the time period over which the related services are performed and compares the level of effort expended through the end of each period with the cumulative expenses recorded and payments made for such services. As appropriate, the Company accrues additional service fees, or defers any nonrefundable advance payments, until the related services are performed. If the actual timing of the performance of services or the level of effort varies from the estimate, the Company adjusts its accrued expenses, or its deferred advance payments, accordingly. If the Company subsequently determines that it no longer expects the services associated with a nonrefundable advance payment to be rendered, the remaining portion of that advance payment is charged to expense in the period in which such determination is made.
Share-Based Compensation
The Company recognizes share-based compensation expense over the service period using the straight-line method. Employee share-based compensation is measured based on estimated fair value as of the grant date. The Company uses the Black-Scholes option-pricing model in calculating the fair value of option grants as of the grant date. The Company uses the following assumptions for estimating fair value of option grants:
Fair Value of Common Stock—The fair value of the common stock underlying the option grants is determined based on observable market prices of the Company’s common stock.
Expected Volatility—Volatility is a measure of the amount by which the Company’s share price has fluctuated (i.e., historical volatility) or is expected to fluctuate (i.e., expected volatility) during a period. Beginning in the first quarter of 2019, the Company began using the historical volatility of its common stock to measure expected volatility for future option grants. Prior to the first quarter of 2019, volatility was estimated using the volatility of the common stock of several public entities of similar size, complexity, and stage of development, as well as taking into consideration the Company’s actual volatility since the Company’s IPO in 2012.
Dividend Yield—The Company has never declared or paid dividends, and has no plans to do so in the foreseeable future.
Expected Term—This is the period of time during which options are expected to remain unexercised. Options have a maximum contractual term of ten years. Beginning in the first quarter of 2019, the Company began estimating the average expected life of stock options using its historical experience. Prior to the first quarter of 2019, the Company determined the

12

Table of Contents


average expected life of stock options according to the “simplified method”, as described in Staff Accounting Bulletin 110, which is the mid-point between the vesting date and the end of the contractual term.
Risk-Free Interest Rate—This is the U.S. Treasury Note rate as of the week each option grant is issued, with a term that most closely resembles the expected term of the option.
Expected Forfeiture Rate—Forfeitures are accounted for as they occur.
Self-insurance Liabilities
As of January 1, 2019, the Company self-insures its employee medical insurance liability. The self-insurance liability is undiscounted and is determined actuarially. It is based on claims filed, historical and industry claims experience, and an estimate of claims incurred but not yet paid. The Company has established stop-loss amounts that limit the Company’s further exposure after a claim reaches the designated stop-loss threshold, which effectively transfers any additional liability to a third party. The stop-loss limit for self-insured employee medical claims is $150,000 per employee per year.
The Company recorded self-insurance liability of approximately $500,000 as of September 30, 2019 in Accrued expenses and other current liabilities on the condensed consolidated balance sheets.
Advertising Expense
Advertising expense includes costs of promotional materials and activities, such as marketing materials, marketing programs and speaker programs. The costs of the Company’s advertising efforts are expensed as incurred.
The Company incurred approximately $11.3 million and $32.5 million in advertising costs for the three and nine months ended September 30, 2019, respectively, and approximately $11.6 million and $30.5 million in advertising costs for the three and nine months ended September 30, 2018, respectively. These expenses are recorded in Selling, general and administrative in the condensed consolidated statements of earnings.
Recently Issued Accounting Pronouncements
Accounting Pronouncements Adopted
In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, “Leases (Topic 842)” and its related amendments (New Lease Standard). The New Lease Standard requires a lessee to recognize a right-of-use lease asset and a corresponding lease liability on the balance sheet. The Company adopted the New Lease Standard on January 1, 2019 using the modified retrospective method, which applies the provision of the New Lease Standard at the effective date without adjusting comparative periods presented. In addition, the Company elected the package of practical expedients permitted under the transition guidance within the New Lease Standard which, among other things, allows the Company to carry forward the historical lease classification.
The adoption of the New Lease Standard resulted in the recognition of lease assets and lease liabilities for operating leases as of January 1, 2019 of approximately $4.0 million. Financial reporting for periods on or after January 1, 2019 are presented under the new guidance. Prior period amounts are not adjusted and continue to be reported in accordance with previous guidance. The standard did not materially impact the Company’s condensed consolidated net earnings and had no impact on cash flows (see Note 14, Leases).
New Accounting Pronouncements Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), which requires credit losses on financial assets measured on an amortized cost basis to be presented at the net amount expected to be collected, rather than based on incurred losses. Further, credit losses on available-for-sale debt securities should be recorded through an allowance for credit losses, limited to the amount by which fair value is below amortized cost. The new standard also requires enhanced disclosure of credit risk associated with respective assets. The standard is effective for fiscal years beginning after December 15, 2019, for interim and annual periods within those years, with early adoption permitted. The Company is currently assessing the impact of this new standard and expects the adoption of the guidance will not have a material impact on its condensed consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred

13

Table of Contents


in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU also requires the entity to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement, which includes reasonably certain renewals. The standard is effective for the Company in the year ending December 31, 2020, with early adoption permitted. The Company is currently assessing the impact of this new standard and expects the adoption of the guidance will not have a material impact on its condensed consolidated financial statements.

In November 2018, the FASB issued ASU 2018-18, Clarifying the Interaction Between Topic 808 and Topic 606, which clarifies when transactions between participants in a collaborative arrangement are within the scope of the FASB’s revenue standard, Topic 606. The standard is effective for the Company in the year ending December 31, 2020, with early adoption permitted. The Company is currently assessing the impact of this new standard and expects the adoption of the guidance will not have a material impact on its condensed consolidated financial statements.

Fair Value of Financial Instruments
The fair value of an asset or liability represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between arm's length market participants.
The Company reports assets and liabilities measured at fair value using a three level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:
Level 1—Inputs are unadjusted quoted prices in active markets for identical assets that the Company has the ability to access as of the measurement date.
Level 2—Inputs are: quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates; yield curves); and inputs that are derived principally from or corroborated by observable market data by correlation or other means (i.e., market corroborated inputs).
Level 3—Unobservable inputs that reflect the Company’s own assumptions, based on the best information available, including the Company’s own data.

Convertible Senior Notes Due 2023
The 0.625% Convertible Senior Notes Due 2023 (2023 Notes), which were issued in March 2018, bear interest at an annual rate of 0.625%, payable semi-annually in arrears on April 1 and October 1 of each year. The 2023 Notes will mature on April 1, 2023, unless earlier converted or repurchased by the Company. The Notes are being amortized to interest expense at an effective interest rate of 5.41% over the contractual term of the 2023 Notes. The Company may not redeem the 2023 Notes at its option before maturity.
The 2023 Notes were issued pursuant to an Indenture between the Company and Wilmington Trust, National Association, as trustee. The Indenture includes customary terms and covenants, including certain events of default upon which the 2023 Notes may be due and payable immediately. The Indenture does not contain any financial or operating covenants or restrictions on the payment of dividends, the issuance of other indebtedness, or the issuance or repurchase of securities by the Company.

17

Table of Contents


The Company will settle conversions by paying or delivering, as applicable, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock, at its election, based on the applicable conversion rate. The initial conversion rate is 16.8545 shares per $1,000 principal amount of the 2023 Notes, which represents an initial conversion price of approximately $59.33 per share, and is subject to adjustment as specified in the Indenture. In the event of conversion, if converted in cash, the holders would forgo all future interest payments, any unpaid accrued interest and the possibility of further stock price appreciation.
If a “make-whole fundamental change,” as defined in the Indenture, occurs, then the Company will in certain circumstances increase the conversion rate for a specified period of time. If a “fundamental change,” as defined in the Indenture, occurs, then noteholders may require the Company to repurchase their 2023 Notes at a cash repurchase price equal to the principal amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest, if any.
Contemporaneous with the issuance of the 2023 Notes, the Company also entered into separate privately negotiated convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions) with each of the call spread counterparties. The Company issued 402,500 convertible note hedge options. In the event that shares or cash are deliverable to holders of the 2023 Notes upon conversion at limits defined in the Indenture, counterparties to the convertible note hedges will be required to deliver up to approximately 6.8 million shares of the Company’s common stock, or to pay cash to the Company in a similar amount as the value that the Company delivers to the holders of the 2023 Notes, based on a conversion price of $59.33 per share.
Concurrently with entering into the Convertible Note Hedge Transactions, the Company also entered into separate privately negotiated warrant transactions (collectively, the Warrant Transactions) with each of the call spread counterparties. The Company issued a total of 6,783,939 warrants. The warrants entitle the holder to one share per warrant at the strike price through 2023. The strike price of the Warrant Transactions will initially be $80.9063 per share of the Company’s common stock, and is subject to adjustment.
The Convertible Note Hedge Transactions are expected to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2023 Notes, as the case may be. The Warrant Transactions are intended to partially offset the cost to the Company of the purchased Convertible Note Hedge Transactions; however, the Warrant Transactions could have a dilutive effect with respect to the Company’s common stock to the extent that the market price per share of the Company’s common stock, as measured under the terms of the Warrant Transactions, exceeds the strike price of the warrants.

Earnings per Share
Basic earnings per share (EPS) is calculated using the weighted-average number of common shares outstanding. Diluted EPS is calculated using the weighted-average number of common shares outstanding, including the dilutive effect of the Company’s stock option grants, stock appreciation rights (SAR), warrants, employee stock purchase plan (ESPP) awards and the 2023 Notes, as determined per the treasury stock method.

Effect of Convertible Notes and Related Convertible Note Hedges and Warrants

In connection with the issuance of the 2023 Notes, the Company entered into Convertible Note Hedge and Warrant Transactions as described further in Note 9, Convertible Senior Notes Due 2023. The expected collective impact of the Convertible Note Hedge and Warrant Transactions is to reduce the potential dilution that may occur from the actual conversion of the 2023 Notes between the conversion price of $59.33 per share and the strike price of the warrants of $80.9063 per share.

The 2023 Notes and related Convertible Note Hedge and Warrant Transactions are excluded in the calculation of diluted EPS because their inclusion would be anti-dilutive. The denominator of the diluted EPS calculation excludes additional shares related to the 2023 Notes and warrants since the average price of the Company's common stock was less than the conversion price of the 2023 Notes of $59.33 per share and the strike price of the warrants of $80.9063 per share. Prior to actual conversion for

purposes of calculating diluted earnings per share, the Convertible Note Hedge Transactions are not considered as their impact would be anti-dilutive.

In addition to the above described effect of the 2023 notes and the related Convertible Note Hedge and Warrant Transactions, the Company also excluded the common stock equivalents for outstanding stock-based awards in the calculation of diluted EPS because their inclusion would be anti-dilutive:

The increase in income tax expense and the increase in the effective tax rate for the three months ended September 30, 2019, as compared to the same period in the prior year, was primarily attributable to income growth, state income tax rate changes, greater 2018 research and development credit and larger employee stock option tax benefits realized in 2018.
The increase in income tax expense and the increase in the effective tax rate for the nine months ended September 30, 2019, as compared to the same period in the prior year, was primarily attributable to the tax benefits realized in 2018 related to exercise of employee stock options.
14.
Leases
The Company determines if an arrangement is a lease at its inception. Some leases include options to terminate prior to the end of the lease term, or to extend for one or more years. These options are included in the lease term when it is reasonably certain that the option will be exercised.

20

Table of Contents


The Company has lease arrangements that contain lease components (e.g., minimum rent payments) and non-lease components (e.g., maintenance, labor charges, etc.). It accounts for both of these components as a single lease component. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.
Operating leases are included in Lease assets, Accrued expenses and other current liabilities, and Lease liabilities, long term on the condensed consolidated balance sheets. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Operating lease assets and lease liabilities are recognized at the commencement date based on the present value of the future minimum lease payments over the lease term. The Company calculates the present value of future payments by using an estimated incremental borrowing rate which approximates the rate at which the Company would borrow, on a secured basis and over a similar term. This rate is estimated based on information available at commencement date of the lease, and may differ for individual leases or for portfolios of leased assets. The Company recognizes lease expense for these leases on a straight-line basis over the lease term. Lease expense for operating leases is recognized as an operating cost.
The Company has operating leases for its current headquarters office and lab space at 1550 East Gude Drive in Rockville, MD and for its fleet vehicles. The Company’s existing leases for its current headquarters office and lab space run through April 2020. With respect to the fleet vehicle leases, given the volume of individual leases involved in the overall arrangement, the Company applies a portfolio approach to effectively account for the operating lease assets and liabilities.
New Headquarters Lease
The Company entered into a new lease agreement, effective January 31, 2019, with Advent Key West, LLC (Landlord), for its new headquarters in Rockville, MD (Premises). The term of the new headquarters lease commenced on February 1, 2019 (the Commencement Date) and will continue until April 30, 2034, unless earlier terminated in accordance with the terms of the lease. The lease includes options to extend the lease for up to 10 years. Fixed rent with respect to the Premises began on the Commencement Date; however, the Landlord agreed to a rent abatement from the Commencement Date through April 30, 2020. The initial fixed rental rate is approximately $195,000 per month for the first 12 months, and will automatically increase by 2% on each anniversary of the Commencement Date. Under the terms of the Lease, the Company provided a security deposit of approximately $195,000, and will be required to pay all utility charges for the Premises in addition to its pro rata share of any operating expenses and real estate taxes. The Company will occupy the Premises upon completion of the build-out of the Premises.
The lease also provides for a tenant improvement allowance of approximately $10.2 million, in aggregate. Any unspent tenant improvement allowance as of January 31, 2020 will be forfeited. The full amount of the tenant improvement allowance was initially recorded in Prepaid expenses and other current assets on the condensed consolidated balance sheets.

also obligated to pay royalties to third parties, as percentage of net product sales, for each respective product under license agreement.
Royalty Agreement
In the third quarter of 2014, the Company received a $30.0 million payment pursuant to a Royalty Interest Acquisition Agreement related to the purchase by HC Royalty of certain of the Company’s rights under the Company’s agreement with United Therapeutics related to the commercialization of Orenitram (treprostinil) Extended-Release Tablets. Full ownership of the royalty rights will revert to the Company if and when a certain cumulative payment threshold is reached, per the terms of the agreement. The Company recorded a nonrecourse liability related to this transaction, and amortizes this amount as noncash royalty revenue (see Note 16). The Company also recognizes noncash interest expense related to this liability and accrues interest expense at an effective interest rate (see Note 10). The interest rate is determined based on projections of HC Royalty’s rate of return.

Overview
We are a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases in neurology and psychiatry.
We market two products, Oxtellar XR and Trokendi XR, in the United States (U.S.), through our own sales force. We seek strategic collaborations with other pharmaceutical companies to commercialize our products outside of the U.S. via license agreements.
In addition, we are developing multiple proprietary product candidates in the CNS market to address unmet medical needs with significant market opportunities.

The table below summarizes our current portfolio of novel products and product candidates:

*
Prophylaxis of migraine headache in adults and adolescents.
**
Initially for Impulsive Aggression (IA) in patients with attention deficit hyperactivity disorder (ADHD), with plans to add other indications, such as IA in patients with post traumatic stress disorder (PTSD), bipolar disorder, Alzheimer’s and other forms of dementia.

We devote significant resources to research and development of products and proprietary drug technologies. We expect to incur significant expenses as we: invest in research and development related to the continued development of each of our product candidates through FDA approval or until the program terminates; expand product indications for approved products; invest in sales and marketing resources for existing and new products; enter into agreements to purchase products or other companies; and invest in support of our business, technology, regulatory and intellectual property portfolio.
Our Neurology Portfolio
Our neurology portfolio includes two commercial products and one product candidate for the treatment of neurological diseases.
Commercial Products
Trokendi XR is a once-daily extended release topiramate product for the prophylaxis of migraine headache and for the treatment of epilepsy.
Oxtellar XR is a once-daily extended release oxcarbazepine product that was initially approved for adjunctive treatment of partial onset seizures of epilepsy. During the first quarter of 2019, we launched Oxtellar XR for the recently approved monotherapy treatment of partial onset seizures of epilepsy in adults and in children 6 to 17 years of age.
These two commercial products differ from immediate release formulations by offering once-daily dosing and unique pharmacokinetic profiles, which we believe can have very positive clinical effects for many patients. We believe a once-daily dosing regimen improves adherence, making it more probable that patients maintain sufficient levels of medication in their bloodstreams to protect against seizures and migraines. In addition, we believe that the unique smooth and steady pharmacokinetic profiles of our once-daily formulations reduce the peak to trough blood level fluctuations, which are typically associated with immediate release products and which may result in increased adverse events (AEs), more side effects and decreased efficacy.

Product Candidate
SPN-817 (huperzine A)
SPN-817 will utilize a novel synthetic form of huperzine A, whose mechanism of action (MOA) includes potent acetyl cholinesterase inhibition with pharmacological activities in CNS conditions such as epilepsy.
SPN-817 Development Program
We plan on studying SPN-817 initially in severe pediatric epilepsy disorders. A Phase I proof-of-concept trial is currently underway outside the U.S. in adult patients with refractory complex partial seizures to study the efficacy, safety and pharmacokinetic profile of a new extended release formulation of non-synthetic huperzine A.
We are completing and optimizing the synthesis process for manufacturing synthetic huperzine A and developing a novel dosage form prior to conducting additional clinical trials. Given the potency of huperzine A, a novel extended release oral dosage form is critical to the success of this program because initial studies with the immediate release formulations of non-synthetic huperzine A have shown dose-limiting, serious side effects.
Our Psychiatry Portfolio
Our psychiatry portfolio includes four product candidates for the treatment of psychiatric disorders.
Product Candidates
SPN-812 (extended release viloxazine hydrochloride)
Viloxazine, the active ingredient in SPN-812, is a structurally distinct, bicyclic, serotonin norepinephrine modulating agent (SNMA) with New Chemical Entity (NCE) status in the U.S. We are developing SPN-812 as a novel treatment for ADHD in pediatric and adolescent patients. We believe that SPN-812 could be a better alternative than other non-stimulant and stimulant ADHD therapies due to its unique pharmacological and pharmacokinetic profile.
Viloxazine has an extensive safety record in Europe, where it was previously marketed for many years as an antidepressant.

Table of Contents


SPN-812 Development Program
Our Phase III program consisted of four three-arm, placebo-controlled trials: P301 and P303 trials in patients 6 to 11 years old, and P302 and P304 trials in patients 12 to 17 years old. In December 2018, we announced positive topline results from the pediatric trials (P301 and P303) and the first adolescent trial (P302). In March 2019, we announced topline results from the second adolescent trial (P304), supporting the positive results seen in the three previous Phase III trials. The Phase III program for SPN-812 is complete. Patients completing the Phase III trials were permitted to continue treatment under our open label extension trial. That trial is on-going and is expected to continue through 2020, or until our NDA is approved.
In addition, we initiated a Phase III program in adults in the third quarter of 2019.
The Company continues to focus on compiling the New Drug Application (NDA) for SPN-812 for submission to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019. We expect to launch SPN-812, assuming FDA approval, in the second half of 2020.
We are continuing to develop and expand our intellectual property (IP) portfolio covering the novel synthesis process for the active ingredient in SPN-812, its novel use in treatment of ADHD and its novel extended release delivery.
SPN-810 (molindone hydrochloride)
We are developing SPN-810 as a novel treatment for IA in patients who have ADHD, with the potential to be the first product available to address this serious, unmet medical need. Molindone hydrochloride was previously marketed in the U.S. for the treatment of schizophrenia, under the trade name Moban, at much higher strengths and using different dosage forms than we are using in our development program. If we are successful in developing SPN-810 as a novel treatment for IA in patients who have ADHD, we may then develop the product as a candidate for treating IA in other indications; e.g., patients with IA in PTSD; bipolar disorder; Alzheimer’s; and other forms of dementia.
SPN-810 Development Program
Our Phase III program consists of two clinical studies in patients 6 to 11 years old (P301 and P302) and one in patients 12 to 17 years old (P503).

In November 2019, we announced topline results from the Phase III P301 trial. The P301 trial did not meet its primary endpoint. The study was a randomized, double-blind, placebo controlled, multicenter, parallel group clinical trial in patients diagnosed with ADHD. Patients receiving SPN-810 36mg showed a median percent reduction of 58.6% in the average weekly frequency of impulsive aggression episodes from baseline that was not statistically significant (p= 0.092) compared to placebo. These results are based on the combined analysis of data from stages 1 and 2 in the study. In stage 1 (interim analysis stage), the median percent reduction was 60%, which was statistically significant (p= 0.029) compared to placebo. However, in stage 2 of the study, post the interim analysis, the increase in variability in the 36mg treatment arm seems to have adversely impacted the results of the combined analysis.

The median percent reduction in frequency of IA behavior in this Phase III study is consistent with the range of percent improvement in the retrospective modified aggression scale (58% - 62%) we saw in the two positive treatment arms in the Phase IIb study. We will continue to analyze the results to better understand the reasons behind the increased variability in the 36mg treatment arm in the P301 study.

Overall, the trial exhibited favorable tolerability and safety profiles with low incidence of AEs across all doses. AEs were mild leading to low discontinuation rates of 0%, 7% and 5% for the 18mg, 36mg and combined treatment arms, respectively.

Enrollment in the Phase III P302 trial in patients 6 to 11 years old is at 98% of the target. We will cease enrollment in the P302 trial and analyze the data, which are expected to be available by the end of 2019. In the meantime, enrollment in the P503 Phase III trial (adolescents) is on hold until data from the P302 study are available and a final decision is reached regarding the SPN-810 program in IA.
We continue to develop and expand our IP portfolio covering the novel synthesis process for the active ingredient in SPN-810, its novel use in IA and its novel extended release delivery.
SPN-809 (viloxazine hydrochloride)
SPN-809 is a novel once-daily product candidate for the treatment of depression. SPN-809 incorporates the same active ingredient as SPN-812, viloxazine hydrochloride.

Because SPN-809 contains the same active ingredient as SPN-812, we expect that many of our activities related to the development of SPN-812 will also benefit the development of SPN-809.
SPN-604 (extended release oxcarbazepine for treatment of bipolar disorder)
We initiated a pivotal Phase III monotherapy trial for the treatment of bipolar disorder in the fourth quarter of 2019. If approved, this would represent the first approval for treatment of bipolar patients with oxcarbazepine in the U.S.

Critical Accounting Policies and the Use of Estimates
The significant accounting policies and bases of presentation for our condensed consolidated financial statements are described in Part I, Item 1, Financial Statements, Note 2, Summary of Significant Accounting Policies in the Notes to the Condensed Consolidated Financial Statements. Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP), requiring us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses, and to disclose material contingent assets and liabilities. Actual results could differ materially from our estimates.
We believe the following accounting policies and estimates to be critical:
Revenue Recognition
Revenue from product sales is recognized when physical control of our products is transferred to our customers, primarily pharmaceutical wholesalers and distributors. Product sales are recorded net of various forms of variable consideration, including: estimated rebates; sales discounts; and an estimated liability for future product returns (collectively, “sales deductions”). We adjust our estimates at the earlier of when the most likely amount of consideration we expect to receive changes, or when the consideration becomes fixed. For a complete description of our revenue recognition policy, see Part I, Item 1, Financial Statements, Note 2, Revenue from Product Sales, in the Notes to Condensed Consolidated Financial Statements.
Research and Development Expenses and Related Accrued Clinical Expenses
Research and development expenditures are expensed as incurred. We estimate preclinical study and clinical trial expenses based on services performed pursuant to contracts with research institutions, clinical investigators, clinical research organizations (CROs) and other services providers that conduct activities on the Company’s behalf.  If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust our accrued expenses or our deferred advance payments accordingly. For a complete description of our research and development expense and preclinical study and clinical trial accrual policies, see Part I, Item 1, Financial Statements, Note 2, Research and Development Expense and Preclinical Study and Clinical Trial Accruals, in the Notes to Condensed Consolidated Financial Statements.
Clinical trials are inherently complex and often involve multiple service providers. Because billing for services often lags by a month or several months, we are often required to estimate, and therefore accrue, a significant portion of our clinical expenses. This process involves reviewing open contracts and communicating with our subject matter expert personnel, as well as

30

Table of Contents


the appropriate service provider personnel to identify services that have been performed on our behalf but for which no invoice has been received. This includes services provided by CROs, as well as services provided by investigators and other service providers. We accrue the cost for unbilled services performed, both partially and fully completed.
Payments to service providers can either be based on hourly rates for service or based on achievement of performance driven milestones. When accruing clinical trial expenses, we estimate the time period over which services will be performed during the life of the entire clinical program, the total cost of the program, and the level of effort to be expended in each intervening period. We work with each service provider to obtain an estimate for services provided but as yet unbilled as of the end of the calendar quarter, including estimates for payments to site investigators.
We work diligently to minimize, if not eliminate, estimates based solely on company generated calculations. We therefore rely primarily on estimates provided by our vendors. If we and/or the service provider underestimates or overestimates the costs associated with a trial or service at any given point in time, adjustments to research and development expenses may be necessary in the following periods. Historically, our estimated accrued clinical expenses have closely approximated the actual expenses incurred.

Net product sales
Net product sales are computed as gross revenue from our product shipments to our customers, which are primarily pharmaceutical wholesalers and distributors, less estimates for rebates, product returns and sales discounts.
In the fourth quarter of 2018, wholesalers, distributors and pharmacies increased their inventory holdings when compared to the prevailing inventory levels in the third quarter of 2018. We estimated that this caused net product sales to be approximately $10 million higher in the fourth quarter of 2018 than it would have been, had channel inventory levels remained consistent from the third to the fourth quarter of 2018. 
The channel inventory build-up in the fourth quarter of 2018 was effectively reversed in the first quarter of 2019. Specifically, based on analysis of sales and inventory data, inventory levels at wholesalers, distributors and pharmacies returned to the prevailing levels of the third quarter of 2018. As a result of this channel inventory reduction, both gross sales and net product sales decreased in the first half of 2019, as compared to the prior year. The adverse impact on net product sales in the first half of 2019 due to the reduction in channel inventory is estimated at approximately $10 million.
On a year over year comparison, the aforementioned $10 million reduction in channel inventory and adverse year over year changes in sales deductions were mostly offset by the favorable unit prescription volume growth of 8% coupled with the

31

Table of Contents


impact of an 8% price increase. On a quarter over quarter comparison, favorable unit prescription volume growth of 6% was mostly offset by higher sales deductions. Specifically as regards sales deductions, patient reimbursement challenges and increased contracting pressure from managed care providers resulted in both increased per patient costs for our co-pay program as well as higher per patient rebate payments to managed care providers. In aggregate, net product sales for the three and nine months ended September 30, 2019 were relatively flat.
Trokendi XR
Trokendi XR net product sales decreased by $2.5 million for the three months ended September 30, 2019 as compared to the same period in 2018. Compared to 2018, favorable unit prescription volume growth of 5% coupled with the impact of an 8% price increase were offset by higher levels of net sales deductions. Increased sales deductions were driven primarily by increased per patient costs for our co-pay program, as well as higher per patient rebate payments to managed care providers.
Trokendi XR net product sales decreased by $6.9 million for the nine months ended September 30, 2019 as compared to the same period in 2018. The primary driver for the decrease was the aforementioned channel inventory reduction coupled with higher net product sales deductions, offsetting prescription volume growth and impact of price increase.
Oxtellar XR
Oxtellar XR net product sales increased by $2.3 million for the three months ended September 30, 2019 as compared to the same period in 2018. Oxtellar XR net product sales increased by $6.0 million for the nine months ended September 30, 2019 as compared to the same period in 2018. In both periods, the increase was attributable to growth in prescription unit volume of 12% and the impact of an 8% price increase taken in January. These effects were partially offset by increased net product sales deductions from higher per patient payments under both Medicaid and managed care programs, as well as higher co-pay program expenditures.
Sales deductions and related accruals
The Company records accrued product rebates and accrued product returns in Accrued product returns and rebates as current liabilities on our condensed consolidated balance sheets and records sales discounts as a valuation allowance against Accounts receivable on the condensed consolidated balance sheets. These outstanding amounts are generally affected by changes in level of gross sales, changes in the provision for net product sales deductions, and timing of payments/credits.
The following table provides a summary of activities with respect to sales deductions and related accruals for the nine months ended September 30, 2019 and 2018, respectively, in thousands of dollars:

The total provision for sales deductions on gross product sales increased from $213.1 million in 2018 to $269.6 million in 2019. A significant portion of this increase was attributable to the year over year increase in the provision for product rebates, from $165.2 million in 2018 to $220.7 million in 2019, or $55.5 million.
    
Year over year increase in the provision for product rebates is primarily attributable to greater utilization of our patient co-pay programs, as well as higher per patient payments under both Medicaid and managed care programs. Growth in prescriptions and the impact of the 8% price increase taken in January also contributed to the increase in product rebates.
The $1.0 million decrease in the provision for product returns from $6.3 million to $5.3 million for the nine months ended September 30, 2018 and 2019, respectively, is due primarily to favorable returns experience.
The provision for sales discounts increased by $2.1 million, from $41.6 million to $43.7 million for the nine months ended September 30, 2018 and 2019, respectively, because of the prescription volume growth.
Adjustments related to prior year sales due to changes in our estimates was $1.8 million as compared to $285.5 million of net product sales for the nine months ended September 30, 2019, and $1.8 million as compared to $286.4 million of net product sales for the same period in prior year.
Royalty Revenues
Royalty revenues include royalty from net product sales of Mydayis, a product of Shire Plc (a subsidiary of Takeda Pharmaceuticals Company Ltd.), as well as noncash royalty revenue pursuant to our agreement with Healthcare Royalty Partners III, L.P. (HC Royalty). HC Royalty receives royalty payments from United Therapeutics Corporation (United Therapeutics) based on net product sales of United Therapeutics' product Orenitram. Supernus records noncash royalty revenue based on such product sales.
Royalty revenues decreased by approximately $0.7 million, or 24%, for the three months ended September 30, 2019, compared to the same period in 2018, and increased by $1.0 million, or 17%, in the nine months ended September 30, 2019 as compared to the same period in 2018. The decrease quarter over quarter was primarily due to decreased sales of Mydayis. The year over year increase was primarily due to increased sales of Orenitram. Noncash royalty revenue, which is included in total royalty revenue, was $1.6 million and $5.0 million, respectively, for the three and nine months ended September 30, 2019, and $1.5 million and $4.3 million, respectively, for the three and nine months ended September 30, 2018.

R&D expenses decreased by $3.5 million in the three months ended September 30, 2019 as compared to the same period in 2018. R&D expenses decreased by $10.1 million in the nine months ended September 30, 2019 as compared to the same period in 2018. The decrease in both periods is primarily driven by the completion of the four Phase III clinical trials for SPN-812 in late 2018/early 2019, partially offset by the cost to manufacture registration/validation materials for SPN-812 to support our upcoming NDA filing.

Selling and Marketing. Selling and marketing expenses decreased by $2.4 million in the three months ended September 30, 2019 as compared to the same period in 2018. Increased selling expenses of $1.8 million due to increased employee-related expenses were mostly offset by decreased professional and consulting expenses of $1.3 million. Marketing expenses decreased by $2.9 million primarily due to timing of sample production.
Selling and marketing expenses decreased by $0.4 million in the nine months ended September 30, 2019 as compared to the same period in 2018, due to timing of sample production, offset by increased employee related expenses, including share-based compensation.
General and Administrative. General and administrative expenses increased by $2.1 million and $5.3 million in the three and nine months ended September 30, 2019, respectively, as compared to the same periods in 2018. The increase is primarily due to higher employee-related expenses, including share-based compensation, of $2.0 million quarter over quarter and $4.2 million year over year, and modest increases in professional and consulting fees, facilities cost and insurance.

Interest income increased by $1.1 million for the three months ended September 30, 2019 and $6.3 million for the nine months ended September 30, 2019 as compared to the same periods in 2018, respectively. The increase in both periods was mainly attributable to an increase in cash, cash equivalents and marketable security holdings primarily resulting from the March 2018 issuance of $402.5 million of 0.625% Convertible Senior Notes, due 2023 (2023 Notes).
Interest expense for the three months ended September 30, 2019 remained essentially unchanged compared to the same period in 2018. Interest expense increased by $4.0 million for the nine months ended September 30, 2019 as compared to the same period in 2018, because of noncash interest expense related to the amortization of deferred financing costs and debt discount on the 2023 Notes.
Noncash interest expense related to our nonrecourse royalty liability for the three months ended September 30, 2019, remained unchanged as compared to the same periods in 2018. Noncash interest expense for the nine months ended September

The increase in income tax expense and the increase in the effective tax rate for the three months ended September 30, 2019, as compared to the same period in the prior year, was primarily attributable to income growth, state income tax rate changes, greater 2018 research and development credit and larger employee stock option tax benefits realized in 2018.
The increase in income tax expense and the increase in the effective tax rate for the nine months ended September 30, 2019, as compared to the same period in the prior year, was primarily attributable to the tax benefits realized in 2018 related to exercise of employee stock options. In particular, the Company recorded income tax benefits related to the exercise of employee stock options of approximately $30,000 and $400,000 for the three and nine months ended September 30, 2019, respectively, as compared to $700,000 and $7.0 million for the three and nine months ended September 30, 2018, respectively.
Liquidity and Capital Resources
We have financed our operations primarily with cash generated from product sales, supplemented by revenue from royalty and licensing arrangements as well as proceeds from the sale of equity and debt securities. As regards continued cash generation, we are highly dependent on the commercial success of our two commercial products, Trokendi XR and Oxtellar XR.
We were cash flow positive and profitable from operations in the nine months ended September 30, 2019. While we expect continued profitability for the current year and in subsequent years, we anticipate there may be significant variability from quarter to quarter in our profitability, and particularly as we move forward with the anticipated commercial launch of SPN-812 in 2020, assuming FDA approval.

We believe our existing cash and cash equivalents, marketable securities and cash received from product sales will be sufficient to finance ongoing operations and to finance development of our new products and label expansions for existing products. To continue to grow our business over the long-term, we plan to commit substantial resources to: product acquisition; product in-licensing; product development and clinical trials of product candidates; and supportive functions such as compliance, finance, management of our intellectual property portfolio, information technology systems and personnel. In each case, spending would be commensurate with the growth of the business.

We may, from time to time, consider additional funding through a combination of new collaborative arrangements, strategic alliances, additional equity and debt financings, or financing from other sources, especially in conjunction with opportunistic acquisitions or licensing arrangements. We will continue to actively manage our capital structure and to consider all financing opportunities that could strengthen our long-term liquidity profile.  Any such capital structure may or may not be similar to transactions in which we have engaged in the past. There can be no assurances that any such financing opportunities will be available on acceptable terms, if at all.

The total cash and cash equivalents, marketable securities and long term marketable securities increased by $118.3 million in the first nine months of 2019 primarily from cash generated from operations for the period.
Our working capital at September 30, 2019 was $277.4 million, a decrease of $54.8 million compared to $332.1 million at December 31, 2018. The decrease was primarily due to increased investment in long term marketable securities of approximately $177.6 million in the nine months ended September 30, 2019.
As of September 30, 2019, the outstanding principal on the 2023 Notes was $402.5 million. No 2023 Notes were converted as of September 30, 2019. Contemporaneous with the issuance of the 2023 Notes, the Company also entered into separate convertible note hedge transactions (collectively, the Convertible Note Hedge Transactions). The Company issued 402,500 convertible note hedge options. The Convertible Note Hedge Transactions are expected to reduce the potential dilution of the Company's common stocks upon conversion of the 2023 Notes. Concurrently with entering into the Convertible Note Hedge Transactions, the Company also entered into separate warrant transactions, issuing a total of 6,783,939 warrants (the Warrant Transactions). See Note 9, Convertible Senior Notes Due 2023 in the Notes to the Condensed Consolidated Financial Statements for further discussion of the 2023 Notes and our other indebtedness.
Our stockholders’ equity increased by $104.2 million during the nine months ended September 30, 2019, primarily as a result of net earnings of $79.9 million, unrealized gains on marketable securities of $10.4 million, issuance of common stock of $2.7 million and share-based compensation of $11.2 million.

Operating Activities
Net cash provided by operating activities is comprised of two components: cash provided by operating earnings and cash provided by (used in) changes in working capital. The increase in net cash provided by operating activities is primarily driven by a period over period increase in operating earnings, offset by incremental cash absorbed by additions to working capital. Cash utilized in working capital reflects the timing of cash collections on receivables and settlement of payables as described below.

Investing Activities
Net cash used in investing activities decreased by $270.4 million for the nine months ended September 30, 2019, as compared to the same period in 2018, primarily due to net purchases of marketable securities. This represents the investment of excess cash in long term securities investments as well as the investment of the proceeds from the issuance of $402.5 million in 2023 Notes in March 2018.
Financing Activities
Net cash provided by financing activities decreased to $2.7 million for the nine months ended September 30, 2019 versus $375.2 million provided in the same period in 2018. This year over year decrease is primarily attributable to the issuance of the 2023 Notes, and the related convertible note hedges and warrants, in March 2018.
Contractual Obligations and Commitments
Refer to the “Contractual Obligations and Commitments” section in “Part II, Item 7 — Management’s Discussion and Analysis of Liquidity and Capital Resources” of our Annual Report on Form 10-K for the year ended December 31, 2018, for a discussion of our contractual obligations.
In addition, during the first quarter of 2019, we entered into a new lease agreement with Advent Key West, LLC for our new headquarters in Rockville, MD. Refer to Note 14 in the Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Off-Balance Sheet Arrangements
We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such entities often referred to as structured finance or special purpose entities. These would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes.
In addition, we do not engage in trading activities involving non-exchange traded contracts.
Recently Issued Accounting Pronouncements
On January 1, 2019, we adopted Accounting Standards Codification (ASC) Topic 842, Leases, or ASC 842. For a discussion of new accounting pronouncements, see Note 2 in the Notes to the Condensed Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Item 3.
Quantitative and Qualitative Disclosures About Market Risk
The primary objective of our investment activities is to preserve our capital to fund operations and to facilitate business development activities. We also seek to maximize income from our investments without assuming significant interest rate, liquidity risk or risk of default by investing in investment grade securities, with maturities of four years or less. Our exposure to market risk is confined to investments in cash, cash equivalents, marketable securities and long term marketable securities. As of September 30, 2019, we had unrestricted cash, cash equivalents, marketable securities and long term marketable securities of $893.1 million.
In connection with the 2023 Notes, we have separately entered into Convertible Note Hedge Transactions and Warrant Transactions to reduce the potential dilution of the Company’s common stock upon conversion of the 2023 Notes, and to partially offset the cost to purchase the Convertible Note Hedge Transactions, respectively.

Our cash and cash equivalents consist primarily of cash held at banks, certificates of deposit and money market funds, and have short-term maturities. Our marketable securities consist of investments in commercial paper, investment grade corporate and U.S. government agency and state debt securities, which are reported at fair value. We generally hold these securities to maturities of one to four years. Because of the relatively short period that we hold our investments and because we generally hold these securities to maturity, we do not believe that an increase in interest rates would have any significant impact on the realizable value of our investments. We do not have any currency or other derivative financial instruments other than outstanding warrants to purchase common stock and the convertible note hedges.
We may contract with CROs and investigational sites globally. Currently, we have only one ongoing trial, for SPN-817, outside the U.S. We do not hedge our foreign currency exchange rate risk. Transactions denominated in currencies other than the

Table of Contents


U.S. dollar are recorded based on exchange rates at the time such transactions arise. As of September 30, 2019 and December 31, 2018, substantially all of our liabilities were denominated in the U.S. dollar.
Inflation generally affects us by increasing our cost of labor and the cost of services provided by our vendors. We do not believe that inflation and changing prices over the three and nine months ended September 30, 2019 and 2018 had a significant impact on our condensed consolidated results of operations.
Item 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act has been appropriately recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, to allow timely decisions regarding required disclosure.
We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of September 30, 2019, the end of the period covered by this report. Based on that evaluation, under the supervision and with the participation of our management, including our CEO and CFO, we concluded that our disclosure controls and procedures were effective as of September 30, 2019.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II — OTHER INFORMATION
Item 1.    Legal Proceedings
From time to time and in the ordinary course of business, we may be subject to various claims, charges and litigation. We may be required to file infringement claims against third parties for the infringement of our patents. As of September 30, 2019, the Company has no outstanding litigation.
Item 1A    Risk Factors
Any investment in our business involves a high degree of risk. Before making an investment decision, you should carefully consider the information we include in this Quarterly Report on Form 10-Q, including our condensed consolidated financial statements and related notes; the additional information in the other reports we file with the Securities and Exchange Commission; and the risks described in our Annual Report on Form 10-K for the year ended December 31, 2018. These risks may result in material harm to our business and our financial condition and results of operations. If a material, adverse event were to occur, the market price of our common stock may decline and you could lose part or all of your investment.
Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds
(a)
Sales of Unregistered Securities.
During the three months ended September 30, 2019, the Company granted options to employees to purchase an aggregate of 26,700 shares of common stock at a weighted-average exercise price of $32.53 per share. Once vested, the options are exercisable for a period of ten years from the grant date. These issuances are exempt from registration in reliance on Section 4(a)(2) of the Securities Act as transactions not involving a public offering.
