Notes to Consolidated Financial Statements

For the Nine Months ended September 30, 2017 and 2016

(unaudited)

1.  Organization and Business

Supernus Pharmaceuticals, Inc. (the Company) was incorporated in Delaware and commenced operations in 2005. The Company is a specialty 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 treatment of migraine and epilepsy, and has several proprietary product candidates in clinical development that address the psychiatry market.

The Company launched Oxtellar XR and Trokendi XR in 2013 for the treatment of epilepsy and launched Trokendi XR for the prophylaxis of migraine in adolescents and adults in April 2017.

2.  Summary of Significant Accounting Policies

Basis of Presentation

The Company’s consolidated financial statements include the accounts of Supernus Pharmaceuticals, Inc. and Supernus Europe 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 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 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 Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC.

In the opinion of management, the consolidated financial statements reflect all adjustments necessary to fairly present the Company’s financial position, results of operations, and cash flows for the periods presented. These adjustments are of a normal recurring nature.  The Company currently operates in one business segment.

The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the Company’s future financial results.

Marketable Securities

Marketable securities consist of investments in U.S. Treasury bills and notes, certificates of deposit, various U.S. governmental agency debt securities, corporate and municipal bonds and other fixed income securities. The Company places all investments with government, industrial, or financial institutions whose debt is rated as investment grade. The Company classifies all available-for-sale marketable securities with maturities greater than one year from the balance sheet date as non-current assets.

The Company’s investments are classified as available-for-sale and are carried at estimated fair value. Any unrealized holding gains or losses are reported, net of any tax effects reported, as accumulated other comprehensive income (loss), which is a separate component of stockholders’ equity.

Realized gains and losses, and declines in value judged to be other-than-temporary, if any, are included in consolidated results of operations. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in fair value, which is charged to earnings in that period, and a new cost basis for the security is established. Dividend and interest income is recognized when earned. The cost of securities sold is calculated using the specific identification method.

The Company established the Supernus Supplemental Executive Retirement Plan (SERP) for the sole purpose of receiving funds for executives from a previous SERP and providing a continuing deferral program under the Supernus SERP. As of September 30, 2017 and December 31, 2016, the fair value of the SERP was $313,000 and $275,000, respectively. The fair value of these assets is included within other non-current assets on the consolidated balance sheets. A corresponding non-current liability is also included in the consolidated balance sheets to reflect the Company’s obligation for the SERP. The Company has not made, and has no plans to make, contributions to the SERP. The securities are restricted in nature and can only be used for purposes of paying benefits under the SERP.

Accounts Receivable, net

Accounts receivable are reported on the consolidated balance sheets at outstanding amounts, less an allowance for doubtful accounts and discounts. The Company extends credit without requiring collateral. The Company writes off uncollectible receivables when the likelihood of collection is remote. The Company evaluates the collectability of accounts receivable on a regular basis. An allowance, when needed, is based upon various factors including the financial condition and payment history of customers, an overall review of collections experience on other accounts, and economic factors or events expected to affect future collections experience.

The Company recorded an allowance for expected sales discounts of approximately $8.1 million and $5.6 million as of September 30, 2017 and December 31, 2016, respectively.

Inventories

Inventories, which are recorded at the lower of cost or market, include materials, labor, and other direct and indirect costs and are valued using the first-in, first-out method. The Company capitalizes inventories produced in preparation for commercial launches when it becomes probable that the related product candidates will receive regulatory approval and that the related costs will be recoverable through the commercial sale of the product.

Property and Equipment

Property and equipment are stated at cost. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations. Repairs and maintenance costs are expensed as incurred. Depreciation and amortization are computed using the straight-line method over the following useful lives:

Intangible Assets

Intangible assets consist of patent defense costs, which are deferred legal fees that have been incurred in connection with legal proceedings related to the defense of patents for Oxtellar XR and Trokendi XR. Patent defense costs will be charged to expense in the event of an unsuccessful outcome of the ongoing litigation. Patents are carried at cost less accumulated amortization, which is calculated on a straight-line basis over the estimated useful lives of the patents. Amortization commences in the quarter after the costs are incurred. This amortization period is based initially upon the remaining patent life and is adjusted, if necessary, for any settlements or other changes to the expected useful life of the patent. The carrying value of the patents are assessed for impairment annually during the fourth quarter of each year, or more frequently if impairment indicators exist. There were no indicators of impairment identified as of September 30, 2017.

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment and patent defense costs. The Company assesses the recoverability of its long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If indications of impairment exist, projected future undiscounted cash flows associated with the asset are compared to the carrying amount to determine whether the asset’s value is recoverable. Evaluation of impairment requires judgment, including the estimation of future cash flows, future growth rates and profitability and the expected life over which cash flows will occur. Changes in the Company’s business strategy or adverse changes in market conditions could impact impairment analyses and could require the recognition of an impairment charge equal to the excess of the carrying value of the long-lived assets over its estimated fair value.

There were no indicators of impairment identified for the Company’s long-lived assets as of September 30, 2017.

Deferred Financing Costs

Deferred financing costs consist of financing costs incurred by the Company in connection with the issuance of the Company’s 7.50% Convertible Senior Secured Notes due 2019 (the Notes). The Company amortizes deferred financing costs over the term of the related debt using the effective interest method. When extinguishing debt, the related deferred financing costs are written off.

Preclinical Study and Clinical Trial Accruals

We estimate preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research institutions, clinical investigators, and clinical research organizations (CROs) that conduct these activities on our behalf. In recording service fees, the Company estimates the time period over which the related services will be performed and compares the level of effort expended through the end of each period to the cumulative expenses recorded and payments made for such services. As appropriate, we accrue additional service fees or defer any non-refundable 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 will adjust its accrual or deferred advance payment accordingly. If the Company later determines that it no longer expects the services associated with a nonrefundable advance payment to be rendered, the advance payment will be charged to expense in the period that such determination is made.

Revenue from Product Sales

Revenue from product sales is recognized when persuasive evidence of an arrangement exists; delivery has occurred and title to the product and associated risk of loss has passed to the customer; the price is fixed or determinable; collection from the customer has been reasonably assured; all performance obligations have been met; and returns and allowances can be reasonably estimated. Product sales are recorded net of estimated rebates, chargebacks, allowances, discounts, patient co-pay assistance and other deductions as well as estimated product returns (collectively, “sales deductions”).

Our products are distributed through wholesalers and pharmaceutical distributors. Each of these wholesalers and distributors takes title and ownership to the product upon physical receipt of the product and then distributes our products to pharmacies.

Sales Deductions

Allowances for estimated sales deductions are provided for the following:

·                  Rebates:  Rebates include mandated discounts under the Medicaid Drug Rebate Program, the Medicare coverage gap program, as well as negotiated discounts with commercial healthcare providers. Rebates are amounts owed after the final dispensing of product to a benefit plan participant has occurred and are based upon contractual agreements or legal requirements with the public sector (e.g., Medicaid) and with private sector benefit providers (e.g., commercial managed care providers). The allowance for rebates is based on statutory and contractual discount rates and expected claimed rebates based on a plan provider’s utilization.

Rebates are generally invoiced and paid quarterly in arrears so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an accrual balance for known or estimated prior quarters’ unpaid rebates. If actual rebates vary from estimates, we may need to adjust balances of such rebates to reflect the actual expenditures of the Company with respect to these programs, which would affect revenue in the period of adjustment.

·                  Co-pay assistance:  Patients who pay in cash or have commercial healthcare insurance and meet certain eligibility requirements may receive co-pay assistance from the Company. The intent of this program is to reduce the patient’s out of pocket costs when filling a prescription. Liabilities for co-pay assistance are based on actual program participation as well as estimates of program activity using data provided by third-party administrators.

·                  Distributor/wholesaler deductions and discounts:  U.S. specialty distributors and wholesalers are offered various forms of consideration including allowances, service fees and prompt payment discounts as consideration for distributing our products. Distributor allowances and service fees arise from contractual agreements with distributors and are generally a percentage of the price at which the Company sells product to distributors and wholesalers. Wholesale customers are offered a prompt pay discount for payment within a specified period.

·                  Returns:  Sales of our products are not subject to a general right of return; however, the Company will accept product that is damaged or defective when shipped directly from our warehouse. The Company will accept expired product six months prior to and up to 12 months subsequent to its expiry date. Product that has been used to fill patient prescriptions is no longer subject to any right of return.

·                  Chargebacks:  Chargebacks are discounts that occur when contracted customers purchase directly from an intermediary distributor or wholesaler. Contracted customers, which currently consist primarily of Public Health Service institutions and federal government entities purchasing via the Federal Supply Schedule, generally purchase our product at a discounted price. The distributor or wholesaler, in turn, charges back the difference between the price initially paid by the distributor or wholesaler and the discounted price paid to the distributor or wholesaler by the customer. The allowance for distributor/wholesaler chargebacks is based on sales to contracted customers.

Revenue Recognition of License Revenue

License and Collaboration Agreements

We have entered into collaboration agreements to commercialize both Oxtellar XR and Trokendi XR outside of the U.S. These agreements generally include an up-front license fee and ongoing milestone payments upon the achievement of specific events. We believe that when milestones meet all of the necessary criteria to be considered substantive, these should be recognized as revenue when achieved. As regards to up-front license fees, we have estimated the service period of the contract and are recognizing revenue on a straight-line basis over the respective service period.

Milestone Payments

Milestone payments on licensing agreements are recognized as revenue when the collaborative partner acknowledges completion of the milestone and substantive effort was necessary to achieve the milestone. Management may recognize milestone revenue in its entirety in the period in which the milestone is achieved only if the milestone meets all the criteria to be considered substantive. Substantive milestone payments are recognized upon achievement only if all of the following conditions are met:

·                  the milestone payments are non-refundable;

·                  achievement of the milestone involves a degree of risk and was not reasonably assured at the inception of the arrangement;

·                  substantive effort on the partner’s part is involved in achieving the milestone; and

·                  the amount of the milestone payment is reasonable in relation to the effort expended or the risk associated with achievement of the milestone.

Determination as to whether a payment meets the aforementioned conditions involves management’s judgment. If any of these conditions are not met, the resulting payment would not be considered a substantive milestone. Therefore, the resulting payment would be considered part of the consideration for the single unit of accounting and amortized over the appropriate period.

The Company recorded $0.3 million and $1.5 million of milestone revenue during the three and nine month periods ended September 30, 2017, respectively. No milestone revenue was recorded during the three and nine months ended September 30, 2016.

Royalty Revenue

We recognize non-cash royalty revenue for royalty amounts earned pursuant to a royalty agreement with United Therapeutics. In 2014, the Company sold certain of these royalty rights to Healthcare Royalty Partners III, L.P. (HC Royalty) (see Note 14). Accordingly, the Company records non-cash royalty revenue when payments are 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 Pharmaceuticals based on net product sales of Mydayis.

Cost of Product Sales

The cost of product sales consists primarily of materials, third-party manufacturing costs, freight and distribution costs, allocation of labor, quality control and assurance, and other manufacturing overhead costs.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs consist primarily of: employee-related expenses, including salaries and benefits; share-based compensation expense; expenses incurred under agreements with CROs; fees paid to clinical investigators who are participating in our clinical trials; fees paid to consultants and other vendors that conduct the Company’s clinical trials; the cost of acquiring and manufacturing clinical trial materials; the cost of manufacturing materials used in process validation, to the extent that those materials are manufactured prior to receiving regulatory approval for those products and are not expected to be sold commercially; facilities costs that do not have an alternative future use; related depreciation and other allocated expenses; license fees for, and milestone payments related to in-licensed products and technologies; and costs associated with animal testing activities and regulatory approvals.

Advertising Expense

The costs of the Company’s advertising efforts are expensed as incurred. The Company incurred approximately $9.6 million and $26.1 million in advertising costs for the three and nine months ended September 30, 2017 and approximately $4.9 million and $16.2 million in advertising costs for the three and nine months ended September 30, 2016, respectively. These expenses are recorded in the selling, general and administrative expense line of the Statement of Operations.

Share-Based Compensation

Employee share-based compensation is measured based on the estimated fair value on the grant date. The grant date fair value is calculated using the Black-Scholes option-pricing model, which requires the use of subjective assumptions including volatility, expected term, risk-free rate, and the fair value of the underlying common stock. The Company recognizes expense using the straight-line method.

The Company records the expense for stock option grants to non-employees based on the estimated fair value of the stock option using the Black-Scholes option-pricing model. The fair value of non-employee awards is re-measured at each reporting period. As a result, stock compensation expense for non-employee awards with vesting is affected by subsequent changes in the fair value of the Company’s common stock.

Income Taxes

The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. When appropriate, valuation allowances are established to reduce deferred tax assets to the amounts expected to be realized.

The Company accounts for uncertain tax positions in its consolidated financial statements when it is more-likely-than-not that the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority, assuming full knowledge of the position and relevant facts. The Company’s policy is to recognize any interest and penalties related to income taxes as income tax expense.

Recently Issued Accounting Pronouncements

Accounting Pronouncements Adopted in 2017

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. The Company adopted ASU 2016-09 on January 1, 2017 using the modified retrospective approach. As a result, the Company recorded a cumulative effect adjustment of $211,000 to increase the 2017 beginning of period additional paid-in capital balance, with an offset to accumulated deficit for historical forfeiture assumptions. Additionally, the Company recorded an opening balance sheet adjustment of $392,000 to increase its deferred tax asset, with an offset to accumulated deficit, primarily to recognize excess tax benefits (i.e. windfalls) from stock option exercises in prior years combined with the impact of the $211,000 adjustment to historical forfeiture expense.

New Accounting Pronouncements Not Yet Adopted

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 provides new guidance about income statement classification and eliminates the requirement to separately measure and report hedge ineffectiveness. The entire change in fair value for qualifying hedge instruments included in the effectiveness will be recorded in other comprehensive income (OCI) and amounts deferred in OCI will be reclassified to earnings in the same income statement line item in which the earnings effect of the hedged item is reported. This standard will be effective for the first annual period beginning after December 15, 2018, including interim periods within those periods.  Early adoption is permitted. The Company is currently assessing the impact that this standard will have on its consolidated financial statements, but does not expect it to have a material impact.

In July 2017, the FASB issued ASU 2017-11, “Earnings per share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception.” The amendments in Part I change the classification analysis of certain equity-linked financial instruments (embedded features) with down round features. When determining whether

9

Table of Contents

certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments in Part II recharacterize the indefinite deferral of certain provisions of Topic 480 with a scope exception and do not have an accounting effect. The amendments in Part I of ASU 2017-11 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The amendments in Part II of ASU 2017-11 do not require any transition guidance because those amendments do not have an accounting effect. The Company is currently assessing the impact that this standard will have on its consolidated financial statements, but does not expect it to have a material impact.

In May 2017, the FASB issued ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting,” which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 is effective for all annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on the consolidated financial statements and disclosures, but does not expect it to have a material impact.

In March 2017, the FASB issued ASU 2017-08, “Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” The amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount, as the discount continues to be amortized to maturity. ASU 2017-08 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and early adoption is permitted. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment recorded directly to retained earnings as of the beginning of the period of adoption. The Company is currently assessing the impact that this standard will have on its consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” The standard eliminates diversity in the practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The standard requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. We expect the ASU to have a material impact on our assets and liabilities due to the addition of previously classified operating leases, but we do not expect it to have a material impact on our cash flows or results of operations.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” ASU 2014-09 will eliminate transaction-and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principles-based approach for determining revenue recognition. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. The ASU also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, with early adoption being permitted for periods ending after December 15, 2016. The guidance permits two methods of adoption: full retrospective method (retrospective application to each prior reporting period presented) or modified retrospective method (retrospective application with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures). The Company has not selected an adoption methodology.

Since ASU No. 2014-09 supersedes substantially all existing revenue recognition guidance affecting us under the current standard, it could impact revenue and cost recognition across our business processes. The Company’s project plan includes a three-phase approach to implementing this standard update. The Company is currently finalizing phase one, the assessment phase, of the project.  In the assessment phase, we held revenue recognition workshops with our commercial and finance groups and reviewed a sample of revenue arrangements across the business to initially identify a set of applicable qualitative revenue recognition changes related to the new standard. Phase two will include (a) establishing and documenting key accounting positions, (b) assessing the new disclosure requirements, business processes, and control impacts, and (c) beginning to assess the initial quantitative impacts resulting from the initial standard.  Phase three will include (a) finalizing any changes to accounting policies, (b) preparing new disclosures and implementing new business processes and controls as needed, and (c) quantifying the effect of adoption on opening retained earnings.

The Company continues to evaluate the impact of the new standard on the consolidated financial statements and related disclosures and additional differences may be identified as contracts with customers that will impact future periods are executed. The majority of

10

Table of Contents

the Company’s revenue consists of sales of products that represent a single performance obligation where control transfers at the point in time title and risk of loss pass to the customer. The adoption of the new ASU will most likely impact our revenue recognition practices on our product sales with regards to the accounting for variable considerations such as incentives and sales deductions and the related financial statement presentation.

In addition, the Company also has licensing and collaboration arrangements, where it receives milestone and royalty payments. The provisions of the new standard may impact the timing of revenue associated with these arrangements; i.e., may result in acceleration of revenue recognition based on the transfer of control. We expect that disclosures in the notes to the consolidated financial statements related to revenue recognition will be expanded in line with the requirements of the new standard to further describe the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company is in the process of assessing its accounting and forecasting considerations to ensure its ability to record, report, forecast, and analyze results under the new standard.

3.  Fair Value of Financial Instruments

The fair value of an asset or liability should represent the price that would be received to sell an asset or that would be paid to transfer a liability in an orderly transaction between market participants. Such transactions are assumed to occur in the principal or most advantageous market for the asset or liability. Accordingly, fair value is determined based on a hypothetical transaction at the measurement date, considered from the perspective of a market participant rather than from a reporting entity’s perspective.

The Company reports assets and liabilities that are measured at fair value using a three level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs. 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 at 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 (interest rates, yield curves, etc.); and inputs that are derived principally from or corroborated by observable market data by correlation or other means (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.

In accordance with the fair value hierarchy described above, the following tables show the fair value of the Company’s financial assets and liabilities that are required to be measured at fair value, in thousands:

The fair value of the restricted marketable securities is included within other non-current assets in the consolidated balance sheets.

The Company’s Level 1 assets include cash held with banks, certificates of deposit, and money market funds.

Level 2 assets include the SERP assets, commercial paper and investment grade corporate bonds and other fixed income securities. Level 2 securities are valued using third-party pricing sources that apply applicable inputs and other relevant data into their models to estimate fair value.

Level 3 liabilities include the estimated fair value of the interest make-whole liability associated with the Notes, which are recorded as derivative liabilities. The “make-whole fundamental change” provision (as defined in the Indenture governing the Notes) expired on May 1, 2017.

The carrying amounts of other financial instruments, including accounts receivable, accounts payable and accrued expenses approximate fair value due to their short-term maturities.
