Notes to Consolidated Financial Statements

(unaudited)

(1) Organization and Business Activities

Acorda Therapeutics, Inc. (“Acorda” or the “Company”) is a biopharmaceutical company dedicated to the identification, development and commercialization of novel therapies to improve the lives of people with multiple sclerosis (MS), spinal cord injury (SCI) and other neurological disorders.

The management of the Company is responsible for the accompanying unaudited interim consolidated financial statements and the related information included in the notes to the consolidated financial statements. In the opinion of management, the unaudited interim consolidated financial statements reflect all adjustments, including normal recurring adjustments necessary for the fair presentation of the Company’s financial position and results of operations and cash flows for the periods presented. Results of operations for interim periods are not necessarily indicative of the results to be expected for the entire year.

These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company as of and for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K for such year, as filed with the Securities and Exchange Commission (the SEC).

(2) Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and include the results of operations of the Company and its majority owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include share-based compensation accounting, which are largely dependent on the fair value of the Company’s equity securities. In addition, the Company recognizes Zanaflex revenue based on estimated prescriptions filled. The Company adjusts its Zanaflex inventory value based on an estimate of inventory that may be returned. Actual results could differ from those estimates.

Investments

Both short-term and long-term investments consist of US Treasury bonds. The Company classifies marketable securities available to fund current operations as short-term investments in current assets on its consolidated balance sheets. Marketable securities are classified as long-term investments in long-term assets on the consolidated balance sheets if the Company has the ability and intent to hold them and such holding period is longer than one year. The Company classifies its short-term and long-term investments as available-for-sale. Available-for-sale securities are recorded at fair value of the investments based on quoted market prices.

Unrealized holding gains and losses on available-for-sale securities, which are determined to be temporary, are excluded from earnings and are reported as a separate component of accumulated other comprehensive income (loss).

Premiums and discounts on investments are amortized over the life of the related available-for-sale security as an adjustment to yield using the effective-interest method. Dividend and interest income are recognized when earned. Amortized premiums and discounts, dividend and interest income and realized gains and losses are included in interest income.

Accumulated Other Comprehensive Income

The Company’s accumulated other comprehensive income is comprised of gains and losses on available for sale securities and is recorded and presented net of income tax.

Revenue Recognition

Ampyra

Ampyra is available only through a network of specialty pharmacy providers that provide the medication to patients by mail; Kaiser Permanente, which distributes Ampyra to patients through a closed network of on-site pharmacies; and ASD Specialty Healthcare, Inc. (an AmerisourceBergen affiliate), which distributes Ampyra to the U.S. Bureau of Prisons and the U.S. Department of Veterans Affairs (VA). Ampyra is not available in retail pharmacies. The Company does not recognize revenue from product sales until there is persuasive evidence of an arrangement, delivery has occurred, the price is fixed and determinable, the buyer is obligated to pay the Company, the obligation to pay is not contingent on resale of the product, the buyer has economic substance apart from the Company, the Company has no obligation to bring about the sale of the product, the amount of returns can be reasonably estimated and collectability is reasonably assured. The Company recognizes product sales of Ampyra following shipment of product to a network of specialty pharmacy providers, Kaiser Permanente, and the specialty distributor to the VA. The specialty pharmacy providers, Kaiser Permanente, and the specialty distributor to the VA are contractually obligated to hold no more than an agreed number of days of inventory, ranging from 10 to 30 days.

The Company’s net revenues represent total revenues less allowances for customer credits, including estimated discounts, rebates, and chargebacks. These allowances are recorded for cash consideration given by a vendor to a customer that is presumed to be a reduction of the selling prices of the vendor’s products or services and, therefore, are characterized as a reduction of revenue. At the time product is shipped to specialty pharmacies, Kaiser Permanente and the specialty distributor to the VA, an adjustment is recorded for estimated discounts, rebates, and chargebacks. These allowances are established by management as its best estimate based on available information and will be adjusted to reflect known changes in the factors that impact such allowances. Allowances for discounts, rebates, returns and chargebacks are established based on the contractual terms with customers, historical trends, communications with customers and the levels of inventory remaining in the distribution channel, as well as expectations about the market for the product and anticipated introduction of competitive products. Product shipping and handling costs are included in cost of sales. The Company does not accept returns of Ampyra with the exception of product damages that occur during shipping.

Zanaflex

The Company applies the revenue recognition guidance in Accounting Standards Codification (ASC) 605-15-25, which among other criteria requires that future returns can be reasonably estimated in order to recognize revenue. The amount of future tablet returns is uncertain due to generic competition and customer conversion to Zanaflex Capsules. The Company has accumulated some sales history with Zanaflex Capsules; however, due to existing and potential generic competition and customer conversion from Zanaflex tablets to Zanaflex Capsules, we do not believe we can reasonably determine a return rate at this time. As a result, the Company accounts for these product shipments using a deferred revenue recognition model. Under the deferred revenue model, the Company does not recognize revenue upon product shipment. For these product shipments, the Company invoices the wholesaler, records deferred revenue at gross invoice sales price, and classifies the cost basis of the product held by the wholesaler as a component of inventory. The Company recognizes revenue when prescribed to the end-user, on a first-in first-out (FIFO) basis. The Company’s revenue to be recognized is based on (1) the estimated prescription demand, based on pharmacy sales for its products; and (2) the Company’s analysis of third-party information, including third-party market research data. The Company’s estimates are subject to the inherent limitations of estimates that rely on third-party data, as certain third-party information is itself in the form of estimates, and reflect other limitations. The Company’s sales and revenue recognition reflects the Company’s estimates of actual product prescribed to the end-user. The Company expects to be able to apply a more traditional revenue recognition policy such that revenue is recognized following shipment to the customer when it believes it has sufficient data to develop reasonable estimates of expected returns based upon historical returns and greater certainty regarding generic competition.

characterized as a reduction of revenue when recognized in the vendor’s statement of operations. Adjustments are recordedfor estimated chargebacks, rebates, and discounts. These allowances are established by management as its best estimate based on available information and are adjusted to reflect known changes in the factors that impact such allowances. Allowances for chargebacks, rebates and discounts are established based on the contractual terms with customers, analysis of historical levels of discounts, chargebacks and rebates, communications with customers and the levels of inventory remaining in the distribution channel, as well as expectations about the market for each product and anticipated introduction of competitive products. In addition, the Company records a charge to cost of goods sold for the cost basis of the estimated product returns the Company believes may ultimately be realized at the time of product shipment to wholesalers. The Company has recognized this charge at the date of shipment since it is probable that it will receive a level of returned products; upon the return of such product it will be unable to resell the product considering its expiration dating; and it can reasonably estimate a range of returns. This charge represents the cost basis for the low end of the range of the Company’s estimated returns. Product shipping and handling costs are included in cost of sales.

Qutenza

Qutenza is distributed in the United States by Besse Medical, Inc., a specialty distributor that furnishes the medication to physician offices; and by ASD Specialty Healthcare, Inc., a specialty distributor that furnishes the medication to hospitals and clinics. The Company does not recognize revenue from product sales until there is persuasive evidence of an arrangement, delivery has occurred, the price is fixed and determinable, the buyer is obligated to pay the Company, the obligation to pay is not contingent on resale of the product, the buyer has economic substance apart from the Company, the Company has no obligation to bring about the sale of the product, and the amount of returns can be reasonably estimated and collectability is reasonably assured. This means that, for Qutenza, the Company recognizes product sales following shipment of product to its specialty distributors.

The Company’s net revenues represent total revenues less allowances for customer credits, including estimated rebates, chargebacks, and returns. These allowances are recorded for cash consideration given by a vendor to a customer that is presumed to be a reduction of the selling prices of the vendor’s products or services and, therefore, are characterized as a reduction of revenue. At the time product is shipped, an adjustment is recorded for estimated rebates, chargebacks, and returns. These allowances are established by management as its best estimate based on available information and will be adjusted to reflect known changes in the factors that impact such allowances. Allowances for rebates, chargebacks, and returns are established based on the contractual terms with customers, historical trends, as well as expectations about the market for the product and anticipated introduction of competitive products. Product shipping and handling costs are included in cost of sales.

Milestones and royalties

In order to determine the revenue recognition for contingent milestones, the Company evaluates the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (FASB) guidance on the milestone method of revenue recognition. At the inception of a collaboration agreement the Company evaluates if payments are substantive. The criteria requires that (i) the Company determines if the milestone is commensurate with either its performance to achieve the milestone or the enhancement of value resulting from the Company’s activities to achieve the milestone, (ii) the milestone be related to past performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent milestones can be considered substantive milestones and will be recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements.

In-Process Research and Development

The cost of in-process research and development (IPR&D) acquired directly in a transaction other than a business combination is capitalized if the projects will be further developed or have an alternative future use; otherwise they are expensed. The fair values of IPR&D projects acquired in business combinations are capitalized. Several methods may be used to determine the estimated fair value of the IPR&D acquired in a business combination. The Company utilizes the "income method," and uses estimated future net cash flows that are derived from projected sales revenues and estimated costs. These projections are based on factors such as relevant market size, patent protection, historical pricing and expected industry trends. The estimated future net cash flows are then discounted to the present value using an appropriate discount rate. These assets are treated as indefinite-lived intangible assets until completion or abandonment of the projects, at which time the assets are amortized over the remaining useful life or written off, as appropriate. IPR&D intangible assets which are determined to have had a drop in their fair value are adjusted downward and an expense recognized on the statement of

operations. These are tested at least annually or sooner when a triggering event occurs that could indicate a potential impairment.

Collaborations

The Company recognizes collaboration revenues and expenses by analyzing each element of the agreement to determine if it shall be accounted for as a separate element or single unit of accounting. If an element shall be treated separately for revenue recognition purposes, the revenue recognition principles most appropriate for that element are applied to determine when revenue shall be recognized. If an element shall not be treated separately for revenue recognition purposes, the revenue recognition principles most appropriate for the bundled group of elements are applied to determine when revenue shall be recognized. Payments received in excess of revenues recognized are recorded as deferred revenue until such time as the revenue recognition criteria have been met.

Concentration of Credit Risk

The Company’s principal direct customers as of March 31, 2014 were a network of specialty pharmacies, Kaiser Permanente, and the specialty distributor to the VA for Ampyra, wholesale pharmaceutical distributors for Zanaflex Capsules and Zanaflex tablets, and two specialty distributors for Qutenza. The Company periodically assesses the financial strength of these customers and establishes allowances for anticipated losses, if necessary. Four customers individually accounted for more than 10% of the Company’s product revenue in 2014 and 2013. Four and three customers individually accounted for more than 10% of the Company’s accounts receivable as of March 31, 2014 and December 31, 2013, respectively. The Company’s net product revenues are generated in the United States.

Segment and Geographic Information

The Company is managed and operated as one business which is focused on the identification, development and commercialization of novel therapies that improve neurological function in people with MS, SCI and other disorders of the central nervous system. The entire business is managed by a single management team that reports to the chief executive officer. The Company does not operate separate lines of business with respect to any of its products or product candidates and the Company does not prepare discrete financial information with respect to separate products or product candidates or by location. Accordingly, the Company views its business as one reportable operating segment. Net product revenues reported to date are derived from the sales of Ampyra, Zanaflex and Qutenza in the United States.

Subsequent Events

Subsequent events are defined as those events or transactions that occur after the balance sheet date, but before the financial statements are filed with the Securities and Exchange Commission. The Company completed an evaluation of the impact of any subsequent events through the date these financial statements were issued, and determined there were no subsequent events requiring disclosure in or requiring adjustment to these financial statements.

Recent Accounting Pronouncements

In July 2013, the FASB issued Accounting Standards Update "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" (ASU 2013-11). ASU 2013-11 requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (NOL) carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. ASU 2013-11 is effective prospectively for fiscal years and interim periods within those years, beginning after December 15, 2013 for public entities. The adoption of ASU 2013-11 did not have a significant impact on the Company’s consolidated financial statements.

The Company did not enter into any new acquisitions in the three-month periods ended March 31, 2014 and 2013. The Company finalized its accounting for the acquisition of NeurogesX, Inc, which occurred during the three-month period ended September 30, 2013 with no purchase price adjustments.

(4) Share-based Compensation

During the three-month periods ended March 31, 2014 and 2013, the Company recognized share-based compensation expense of $5.8 million and $4.9 million, respectively. Activity in options and restricted stock during the three-month period ended March 31, 2014 and related balances outstanding as of that date are reflected below. The weighted average fair value per share of options granted to employees for the three-month periods ended March 31, 2014 and 2013 were approximately $18.81 and $15.41, respectively.

The following table summarizes share-based compensation expense included within the consolidated statements of operations:

	For the three-month
	period ended March 31,
(In millions)	2014			2013

Research and development		$	1.1		$	1.2
Selling, general and administrative			4.7			3.7
Total		$	5.8		$	4.9

A summary of share-based compensation activity for the three-month period ended March 31, 2014 is presented below:

Stock Option Activity

	Number of Shares (In thousands)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Intrinsic Value (In thousands)
Balance at January 1, 2014		6,486		$	25.61
Granted		1,329			38.52
Cancelled		(41	)		31.28
Exercised		(144	)		25.40

Forfeited		(6)
Nonvested at March 31, 2014		627

Unrecognized compensation cost for unvested stock options and restricted stock awards as of March 31, 2014 totaled $75.9 million and is expected to be recognized over a weighted average period of approximately 2.9 years.

(5) Earnings Per Share

The following table sets forth the computation of basic and diluted earnings per share for the three-month periods ended March 31, 2014 and 2013:

(In thousands, except per share data)	Three-month period ended March 31, 2014		Three-month period ended March 31, 2013
Basic and diluted
Net income (loss)	$	703	$	(1,139	)
Weighted average common shares outstanding used in computing net income (loss) per share—basic		40,934		39,832
Plus: net effect of dilutive stock options and restricted common shares		1,301		—
Weighted average common shares outstanding used in computing net income (loss) per share—diluted		42,235		39,832
Net income (loss) per share—basic	$	0.02	$	(0.03	)
Net income (loss) per share—diluted	$	0.02	$	(0.03	)

The difference between basic and diluted shares is that diluted shares include the dilutive effect of the assumed exercise of outstanding securities. The Company’s stock options and unvested shares of restricted common stock could have the most significant impact on diluted shares.

Securities that could potentially be dilutive are excluded from the computation of diluted earnings per share when a loss from continuing operations exists or when the exercise price exceeds the average closing price of the Company’s common stock during the period, because their inclusion would result in an anti-dilutive effect on per share amounts.

The following amounts were not included in the calculation of net income per diluted share because their effects were anti-dilutive:

(In thousands)	Three-month period ended March 31, 2014	Three-month period ended March 31, 2013
Denominator
Stock options and restricted common shares	2,764	2,812
Convertible note	29	39

(6) Income Taxes

For the three-month periods ended March 31, 2014 and 2013, the Company recorded a $2.8 million provision for and $1.8 million benefit from income taxes, respectively, based upon its estimated tax liability for the year. The provision for/benefit from income taxes is based on federal, state and Puerto Rico income taxes. The effective income tax rates for the Company for the three-month periods ended March 31, 2014 and 2013 were 80% and (61)%, respectively. As a result of the Federal research and development tax credit not being extended during the first quarter of 2014, the Company was not able to receive a benefit in the effective tax rate for this in 2014.

The Company continues to evaluate the realizability of its deferred tax assets and liabilities on a periodic basis and will adjust such amounts in light of changing facts and circumstances including, but not limited to, future projections of taxable income, tax legislation, rulings by relevant tax authorities, the progress of ongoing tax audits and the regulatory approval of products currently under development. Any changes to the valuation allowance or deferred tax assets in the future would impact the Company's income taxes.

(7) Fair Value Measurements

The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2014 and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset or liability. The Company’s Level 1 assets consist of time deposits and investments in a Treasury money market fund and the Company’s Level 2 assets consist of high-quality government bonds and are valued using market prices on the active markets. Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets and Level 2 assets are valued using quoted prices for similar assets and liabilities in active markets or other market observable inputs such as interest rates and yield curves. The Company’s Level 3 liabilities represent our put/call liability related to the Paul Royalty Fund (PRF) transaction and contingent consideration related to the NeurogesX acquisition. No changes in valuation techniques or inputs occurred during the three months ended March 31, 2014.

(In thousands)	Level 1		Level 2		Level 3

The following tables present additional information about assets and/or liabilities measured at fair value on a recurring basis and for which the Company utilizes Level 3 inputs to determine fair value.

Put/call liability

(In thousands)	Three-month period ended March 31, 2014		Three-month period ended March 31, 2013
Put/call liability:
Balance, beginning of period	$	147	$	329
Total realized and unrealized losses (gains) included in selling, general and administrative expenses:		20		(82	)
Balance, end of period	$	167	$	247

The Company estimates the fair value of its put/call liability using a discounted cash flow valuation technique. Using this approach, historical and expected future cash flows are calculated over the expected life of the PRF agreement, are discounted, and then exercise scenario probabilities are applied. Some of the more significant assumptions made in the valuation include (i) the estimated Zanaflex revenue forecast and (ii) the likelihood of put/call exercise trigger events such as bankruptcy and change of control. The valuation is performed periodically when the significant assumptions change. Realized gains and losses are included in selling, general and administrative expenses.

The put/call liability has been classified as a Level 3 liability as its valuation requires substantial judgment and estimation of factors that are not currently observable in the market due to the lack of trading in the security. If different assumptions were used for the various inputs to the valuation approach including, but not limited to, assumptions involving the estimated Zanaflex revenue forecast and the likelihood of trigger events, the estimated fair value could be significantly

higher or lower than the fair value we determined. The Company may be required to record losses in future periods, which may be significant.

Contingent purchase price

(In thousands)	Three-month period ended March 31, 2014		Three-month period ended March 31, 2013
Contingent purchase price:
Balance, beginning of period	$	236	$	—
Total losses included in selling, general and administrative expenses:		9		—
Balance, end of period	$	245	$	—

The Company measures the fair value of the contingent purchase price using a Monte Carlo simulation. Using this approach, the present value of each of the milestone payments is calculated using the probability of milestone achievement under various different scenarios. Some of the more significant assumptions used in the valuation include (i) the probability of FDA approval for NP-1998 and (ii) the variability in net sales for NP-1998 if FDA approval is achieved. The milestone achievement probabilities range from 0% to 10%, and the milestone payment outcomes range from $0 to $5.0 million. The valuation will be performed periodically when the significant assumptions change. Realized gains and losses are included in selling, general and administrative expenses. There is no assurance that any of the conditions for the milestone payments will be met.

The contingent purchase price has been classified as a Level 3 liability as its valuation requires substantial judgment and estimation of factors that are not currently observable in the market. If different assumptions were used for the various inputs to the valuation approach including, but not limited to, assumptions involving the probability of FDA approval for NP-1998 and the likelihood of trigger events, the estimated fair value could be significantly higher or lower than the fair value we determined. The Company may be required to record losses in future periods.

(8) Investments

The Company has determined that all of its investments are classified as available-for-sale. Available-for-sale securities are carried at fair value with interest on these securities included in interest income and are recorded based primarily on quoted market prices. Available-for-sale securities consisted of the following:

(In thousands)	Amortized Cost		Gross unrealized gains		Gross unrealized losses			Estimated fair value
March 31, 2014
US Treasury bonds	$	327,658	$	141	$	(2	)	$	327,797
December 31, 2013
US Treasury bonds		319,123		69		(2	)		319,190

The contractual maturities of short-term available-for-sale debt securities at March 31, 2014 and December 31, 2013 are greater than 3 months but less than 1 year. The contractual and intended maturities of long-term available-for-sale debt securities at March 31, 2014 and December 31, 2013 are greater than 1 year and up to 16 months. The Company has determined that there were no other-than-temporary declines in the fair values of its investments as of March 31, 2014.

Short-term investments with maturity of three months or less from date of purchase have been classified as cash equivalents, and amounted to $30.7 million and $28.3 million as of March 31, 2014 and December 31, 2013, respectively.

The Company holds available-for-sale investment securities which are reported at fair value on the Company’s balance sheet. Unrealized holding gains and losses are reported within accumulated other comprehensive income (AOCI) in the statements of comprehensive (loss) income. The changes in AOCI associated with the unrealized holding gain on available-for-sale investments during the three months ended March 31, 2014, were as follows (in thousands):

(In thousands)	Net Unrealized Gains on Marketable Securities
Balance at December 31, 2013	$	37
Other comprehensive income before reclassifications:		45
Amounts reclassified from accumulated other comprehensive income		—
Net current period other comprehensive income		45
Balance at March 31, 2014	$	82

(9) Collaborations, Alliances, and Other Agreements

Biogen

On June 30, 2009, the Company entered into an exclusive collaboration and license agreement with Biogen Idec International GmbH (Biogen Idec) to develop and commercialize Ampyra (known as Fampyra outside the U.S.) in markets outside the United States (the “Collaboration Agreement”). Under the Collaboration Agreement, Biogen Idec was granted the exclusive right to commercialize Ampyra and other products containing aminopyridines developed under that agreement in all countries outside of the United States, which grant includes a sublicense of the Company’s rights under an existing license agreement between the Company and Alkermes plc (Alkermes), formerly Elan Corporation, plc (Elan). Biogen Idec has responsibility for regulatory activities and future clinical development of Fampyra in ex-U.S. markets worldwide. The Company also entered into a related supply agreement with Biogen Idec (the “Supply Agreement”), pursuant to which the Company will supply Biogen Idec with its requirements for the licensed products through the Company’s existing supply agreement with Alkermes.

Under the Collaboration Agreement, the Company was entitled to an upfront payment of $110.0 million as of June 30, 2009, which was received in July 2009, and a $25.0 million milestone payment upon approval of the product in the European Union, which was received in August 2011. The Company is also entitled to receive additional payments of up to $10.0 million based on the successful achievement of future regulatory milestones and up to $365.0 million based on the successful achievement of future sales milestones. Due to the uncertainty surrounding the achievement of the future regulatory and sales milestones, these payments will not be recognized as revenue unless and until they are earned. The Company is not able to reasonably predict if and when the milestones will be achieved. Under the Collaboration Agreement, Biogen Idec will be required to make double-digit tiered royalty payments to the Company on ex-U.S. sales. In addition, the consideration that Biogen Idec will pay for licensed products under the Supply Agreement will reflect the price owed to the Company’s suppliers under its supply arrangements with Alkermes or other suppliers for ex-U.S. sales. The Company and Biogen Idec may also carry out future joint development activities regarding licensed product under a cost-sharing arrangement. Under the terms of the Collaboration Agreement, the Company, in part through its participation in joint committees with Biogen Idec, will participate in overseeing the development and commercialization of Ampyra and other licensed products in markets outside the United States pursuant to that agreement. Acorda will continue to develop and commercialize Ampyra independently in the United States.

As of June 30, 2009, the Company recorded a license receivable and deferred revenue of $110.0 million for the upfront payment due to the Company from Biogen Idec under the Collaboration Agreement. Also, as a result of such payment to Acorda, a payment of $7.7 million became payable by Acorda to Alkermes and was recorded as a cost of license payable and deferred expense. The payment of $110.0 million was received from Biogen Idec on July 1, 2009 and the payment of $7.7 million was made to Alkermes on July 7, 2009.

The Company considered the following deliverables with respect to the revenue recognition of the $110.0 million upfront payment: (1) the license to use the Company’s technology, (2) the Collaboration Agreement to develop and commercialize licensed product in all countries outside the U.S., and (3) the Supply Agreement. Due to the inherent uncertainty in obtaining regulatory approval, the applicability of the Supply Agreement is outside the control of the Company and Biogen Idec. Accordingly, the Company has determined the Supply Agreement is a contingent deliverable at the onset of the agreement. As a result, the Company has determined the Supply Agreement does not meet the definition of a deliverable that needs to be accounted for at the inception of the arrangement. The Company has also determined that there is no significant and incremental discount related to the supply agreement since Biogen Idec will pay the same amount for inventory that the Company would pay and the Company effectively acts as a middle man in the arrangement for which it

adds no significant value due to various factors such as the Company does not have any manufacturing capabilities or other know how with respect to the manufacturing process.

The Company has determined that the identified non-contingent deliverables (deliverables 1 and 2 immediately preceding) would have no value on a standalone basis if they were sold separately by a vendor and the customer could not resell the delivered items on a standalone basis, nor does the Company have objective and reliable evidence of fair value for the deliverables. Accordingly, the non-contingent deliverables are treated as one unit of accounting. As a result, the Company will recognize the non-refundable upfront payment from Biogen Idec as revenue and the associated payment to Alkermes as expense ratably over the estimated term of regulatory exclusivity for the licensed products under the Collaboration Agreement as the Company had determined this was the most probable expected benefit period. The Company recognized $2.3 million in license revenue, a portion of the $110.0 million received from Biogen Idec, and $159,000 in cost of license revenue, a portion of the $7.7 million paid to Alkermes, during the three-month periods ended March 31, 2014 and 2013.

On January 21, 2011 Biogen Idec announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) decided against approval of Fampyra to improve walking ability in adult patients with multiple sclerosis. Biogen Idec, working closely with the Company, filed a formal appeal of the decision. In May 2011, the CHMP recommended conditional marketing authorization, and in July 2011 Biogen Idec received conditional approval from the European Commission for, Fampyra (prolonged-release fampridine tablets) for the improvement of walking in adult patients with MS with walking disability (Expanded Disability Status Scale of 4-7). The Company currently estimates the recognition period to be approximately 12 years from the date of the Collaboration Agreement. As part of its ex-U.S. license agreement, Biogen Idec owes Acorda royalties based on ex-U.S. net sales, and milestones based on ex-U.S. regulatory approval, new indications, and ex-U.S. net sales. These milestones included a $25.0 million payment for approval of the product in the European Union which was recorded and paid in the three month period ended September 30, 2011. Based on Acorda’s worldwide license and supply agreement with Alkermes, Alkermes received 7% of this milestone payment from Acorda during the same period. For revenue recognition purposes, the Company determined this milestone to be substantive in accordance with applicable accounting guidance related to milestone revenue. Substantive uncertainty existed at the inception of the arrangement as to whether the milestone would be achieved because of the numerous variables, such as the high rate of failure inherent in the research and development of new products and the uncertainty involved with obtaining regulatory approval. Biogen Idec leveraged Acorda’s U.S. Ampyra study results that contributed to the regulatory approval process. Therefore, the milestone was achieved based in part on Acorda’s past performance. The milestone was also reasonable relative to all deliverable and payment terms of the collaboration arrangement. Therefore, the payment was recognized in its entirety as revenue and the cost of the milestone revenue was recognized in its entirety as an expense during the three-month period ended September 30, 2011.

Actavis/Watson

The Company has an agreement with Watson Pharma, Inc., a subsidiary of Actavis, Inc. (formerly Watson Pharmaceuticals, Inc.), to market tizanidine hydrochloride capsules, an authorized generic version of Zanaflex Capsules which was launched in February 2012. In accordance with the Watson agreement, the Company receives a royalty based on Watson’s gross margin, as defined by the agreement, of the authorized generic product. During the three-month periods ended March 31, 2014 and 2013, the Company recognized royalty revenue of $1.4 million and $2.6 million, respectively, related to the gross margin of the Zanaflex Capsule authorized generic. During the three-month periods ended March 31, 2014 and 2013, the Company also recognized revenue and a corresponding cost of sales of $830,000 and $493,000, respectively, related to the purchase and sale of the related Zanaflex Capsule authorized generic product to Watson, which is recorded in net product revenues and cost of sales.

Neuronex

In December 2012, the Company acquired Neuronex, Inc., a privately-held development stage pharmaceutical company (Neuronex) developing Plumiaz (our trade name for Diazepam Nasal Spray). Plumiaz is a proprietary nasal spray formulation of diazepam that we are developing under Section 505(b)(2) of the Food, Drug and Cosmetic Act as an acute treatment for selected, refractory patients with epilepsy, on stable regimens of antiepileptic drugs, or AEDs, who experience intermittent bouts of increased seizure activity also known as cluster seizures or acute repetitive seizures, or ARS.

Under the terms of the agreement, the Company made an upfront payment of $2.0 million in February 2012. The Company also paid $1.5 million during the twelve month period ended December 31, 2012 pursuant to a commitment under

the agreement to fund research to prepare for the Plumiaz pre-NDA meeting with the FDA. In December 2012, the Company completed the acquisition by paying $6.8 million to former Neuronex shareholders less a $300,000 holdback provision. After adjustment for Neuronex’s working capital upon closing of the acquisition, approximately $120,000 of the holdback amount was remaining as of December 31, 2013. This balance was paid to the former equity holders of Neuronex pursuant to the merger agreement in February 2014.

The former equity holders of Neuronex are entitled to receive from Acorda up to an additional $18 million in contingent earnout payments upon the achievement of specified regulatory and manufacturing-related milestones with respect to Diazepam Nasal Spray products, and up to $105 million upon the achievement of specified sales milestones with respect to Diazepam Nasal Spray products. The former equity holders of Neuronex will also be entitled to receive tiered royalty-like earnout payments, ranging from the upper single digits to lower double digits, on worldwide net sales of Diazepam Nasal Spray products. These payments are payable on a country-by-country basis until the earlier to occur of ten years after the first commercial sale of a product in such country and the entry of generic competition in such country as defined in the Agreement.

The patent and other intellectual property and other rights relating to Diazepam Nasal Spray products are licensed from SK Biopharmaceuticals Co., Ltd. (SK). Pursuant to the SK license, which granted worldwide rights to Neuronex, except certain specified Asian countries, the Company’s subsidiary Neuronex is obligated to pay SK up to $8 million upon the achievement of specified development milestones with respect to the Diazepam Nasal Spray product (including a $1 million payment that was triggered during the three-month period ending September 30, 2013 upon the FDA’s acceptance for review of the first NDA for Plumiaz and paid during the three-month period ending December 31, 2013), and up to $3 million upon the achievement of specified sales milestones with respect to the Diazepam Nasal Spray product. Also, Neuronex is obligated to pay SK a tiered, mid-single digit royalty on net sales of Diazepam Nasal Spray products.

The Company evaluated the transaction based upon the guidance of ASC 805, Business Combinations, and concluded that it only acquired inputs and did not acquire any processes. The Company needed to develop its own processes in order to produce an output. Therefore the Company accounted for the transaction as an asset acquisition and accordingly the $2.0 million upfront payment, $1.5 million in research funding and $6.8 million of closing consideration net of tangible net assets acquired of $3.7 million which were primarily the taxable amount of net operating loss carryforwards, were expensed as research and development expense during the twelve-month period ended December 31, 2012.

(10) Commitments and Contingencies

A summary of the Company’s commitments and contingencies was included in the Company’s Annual Report on Form 10-K for the twelve-month period ended December 31, 2013. The Company’s long-term contractual obligations include commitments and estimated purchase obligations entered into in the normal course of business.

The Company accrues for amounts related to legal matters if it is probable that a liability has been incurred and the amount is reasonably estimable. While losses, if any, are possible, the Company is not able to estimate any ranges of losses as of March 31, 2014. Litigation expenses are expensed as incurred.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our consolidated financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q.

Background

We are a biopharmaceutical company dedicated to the identification, development and commercialization of novel therapies that improve the lives of people with multiple sclerosis, or MS, spinal cord injury, or SCI, and other neurological disorders. We market three FDA-approved therapies, including: Ampyra (dalfampridine) Extended Release Tablets, 10 mg, a treatment to improve walking in patients with MS; Zanaflex Capsules (tizanidine hydrochloride) and Zanaflex tablets, a short-acting drug for the management of spasticity; and Qutenza (capsaicin) 8% Patch, for the management of neuropathic pain associated with postherpetic neuralgia. We have one of the leading pipelines in the industry of novel neurological therapies. We are currently developing six clinical stage therapies and one preclinical stage therapy that address a range of disorders, including post-stroke deficits, epilepsy, stroke, peripheral nerve damage, spinal cord injury, neuropathic pain, and heart failure.

Ampyra

General

Ampyra was approved by the FDA in January 2010 for the improvement of walking in people with MS. To our knowledge, Ampyra is the first and only product approved for this indication. Efficacy was shown in people with all four major types of MS (relapsing remitting, secondary progressive, progressive relapsing and primary progressive). Ampyra was made commercially available in the United States in March 2010. Net revenue for Ampyra was $72.5 million for the three months ended March 31, 2014 and $62.3 million for the three months ended March 31, 2013.

Since the March 2010 launch of Ampyra, more than 90,000 people with MS in the U.S. have tried Ampyra. As of December 2013, approximately 70% of all people with MS who were prescribed Ampyra received a first refill, and approximately 40% of all people with MS who were prescribed Ampyra have been dispensed at least six months of the medicine through refills, consistent with previously reported trends. These refill rates include patients who started Ampyra through our First Step program, which provides eligible patients with a free 60 day trial of Ampyra, but excludes the free prescriptions provided under that program.

Ampyra is marketed in the United States through our own specialty sales force and commercial infrastructure. We currently have approximately 90 sales representatives in the field calling on a priority target list of approximately 7,000 physicians. We also have established teams of Medical Science Liaisons, Regional Reimbursement Directors, Managed Markets Account Directors who provide information and assistance to payers and physicians on Ampyra, National Trade Account Managers who work with our limited network of specialty pharmacies, and Market Development Managers who work collaboratively with field teams and corporate personnel to assist in the execution of the Company’s strategic initiatives.

Ampyra is distributed in the United States exclusively through a limited network of specialty pharmacy providers that deliver the medication to patients by mail; Kaiser Permanente, which distributes Ampyra to patients through a closed network of on-site pharmacies; and ASD Specialty Healthcare, Inc. (an AmerisourceBergen affiliate), which distributes Ampyra to the U.S. Bureau of Prisons and the U.S. Department of Veterans Affairs, or VA. All of these customers are contractually obligated to hold no more than an agreed number of days of inventory, ranging between 10 to 30 days.

We have contracted with a third party organization with extensive experience in coordinating patient benefits to run Ampyra Patient Support Services, or APSS, a dedicated resource that coordinates the prescription process among healthcare providers, people with MS, and insurance carriers. Processing of most incoming requests for prescriptions by APSS begins within 24 hours of receipt. Patients will experience a range of times to receive their first shipment based on the processing time for insurance requirements. As with any prescription product, patients who are members of benefit plans that have restrictive prior authorizations may experience delays in receiving their prescription.

Three of the largest national health plans in the U.S. – Aetna, United Healthcare and Cigna – have listed Ampyra in the lowest competitive reimbursement tier, which means that it is listed in either the lowest branded copay tier or the lowest

branded specialty tier (if more than one specialty tier exists) of their commercial preferred drug list or formulary. Approximately 75% of commercially insured individuals in the U.S. continue to have no or limited prior authorizations, or PA’s, for Ampyra. We define limited PAs as those that require only an MS diagnosis, documentation of no contraindications, and/or simple documentation that the patient has a walking impairment; such documentation may include a Timed 25-Foot Walk (T25W) test. The access figure is calculated based on the number of pharmacy lives reported by commercial health plans.

License and Collaboration Agreement with Biogen Idec

Ampyra is marketed as Fampyra outside the U.S. by Biogen Idec International GmbH, or Biogen Idec, under a license and collaboration agreement that we entered into in June 2009. Fampyra has been approved in a number of countries across Europe, Asia and the Americas. Biogen Idec anticipates making Fampyra commercially available in additional markets in 2014. Under our agreement with Biogen Idec, we are entitled to receive double-digit tiered royalties on sales of Fampyra and we are also entitled to receive additional payments based on achievement of certain regulatory and sales milestones. We received a $25 million milestone payment from Biogen Idec in 2011, which was triggered by Biogen Idec’s receipt of conditional approval from the European Commission for Fampyra. The next expected milestone payment would be $15 million, due when ex-U.S. net sales exceed $100 million over four consecutive quarters.

Ampyra Patent Update

We have five issued patents listed in the Orange Book for Ampyra, one of which issued in 2014, as follows:

The first is U.S. Patent No. 8,007,826, with claims relating to methods to improve walking in patients with MS by administering 10 mg of sustained release 4-aminopyridine (dalfampridine) twice daily. Based on the final patent term adjustment calculation of the United States Patent and Trademark Office, or USPTO, this patent will extend into 2027.

The second is U.S. Patent No. 5,540,938 (“the ‘938 patent”), the claims of which relate to methods for treating a neurological disease, such as MS, and cover the use of a sustained release dalfampridine formulation, such as AMPYRA (dalfampridine) Extended Release Tablets, 10 mg for improving walking in people with MS. In April 2013, the ‘938 patent received a five year patent term extension under the patent restoration provisions of the Hatch Waxman Act. With a five year patent term extension, the ‘938 patent will expire in 2018. We have an exclusive license to this patent from Alkermes (originally with Elan, but transferred to Alkermes as part of its acquisition of Elan’s Drug Technologies business).

The third is U.S. Patent No. 8,354,437, which includes claims relating to methods to improve walking, increase walking speed, and treat walking disability in patients with MS by administering 10 mg of sustained release 4-aminopyridine (dalfampridine) twice daily. This patent is set to expire in 2026.

The fourth is U.S. Patent No. 8,440,703, which includes claims directed to methods of improving lower extremity function and walking and increasing walking speed in patients with MS by administering less than 15 mg of sustained release 4-aminopyridine (dalfampridine) twice daily. This patent is set to expire in 2025.

·	The fifth, which issued in March of 2014, is U.S. Patent No. 8,663,685 with claims relating to methods to improve walking in patients with MS by administering 10 mg of sustained release 4-aminopyridine (dalfampridine) twice daily. Absent patent term adjustment, the patent is set to expire in 2024.

In 2011, the European Patent Office, or EPO, granted EP 1732548, the counterpart European patent to U.S. Patent No. 8,354,437 with claims relating to, among other things, use of a sustained release aminopyridine composition, such as dalfampridine, to increase walking speed. In March 2012, Synthon B.V. and neuraxpharm Arzneimittel GmBH filed oppositions with the EPO challenging the EP 1732548 patent. We defended the patent, and in December 2013, we announced that the EPO Opposition Division upheld amended claims in this patent covering a sustained release formulation of dalfampridine for increasing walking in patients with MS through twice daily dosing at 10 mg. Both Synthon B.V. and neuraxpharm Arzneimittel GmBH have appealed the decision. In December 2013, Synthon B.V., neuraxpharm Arzneimittel GmBH and Actavis Group PTC ehf filed oppositions with the EPO challenging our EP 2377536 patent, which is a divisional of the EP 1732548 patent. Both European patents are set to expire in 2025, absent any additional exclusivity granted based on regulatory review timelines.

Zanaflex

Zanaflex Capsules and Zanaflex tablets are FDA-approved as short-acting drugs for the management of spasticity, a symptom of many central nervous system, or CNS, disorders, including MS and SCI. These products contain tizanidine hydrochloride, one of the two leading drugs used to treat spasticity. We launched Zanaflex Capsules in April 2005 as part of our strategy to build a commercial platform for the potential market launch of Ampyra. Combined net revenue of Zanaflex Capsules and Zanaflex tablets was $0.9 million for the three months ended March 31, 2014 and $1.3 million for the three months ended March 31, 2013. In 2012, Apotex commercially launched a generic version of tizanidine hydrochloride capsules, and we also launched our own authorized generic version, which is being marketed by Watson Pharma (a subsidiary of Actavis). In March 2013, Mylan Pharmaceuticals commercially launched their own generic version of Zanaflex Capsules. The commercial launch of generic tizanidine hydrochloride capsules has caused a significant decline in net revenue from the sale of Zanaflex Capsules, and the launch of these generic versions and the potential launch of other generic versions is expected to cause the Company’s net revenue from Zanaflex Capsules to decline further in 2014 and beyond.

Qutenza and NP-1998; NeurogesX Transaction

In July 2013, we acquired two neuropathic pain management assets from NeurogesX, Inc., including: Qutenza, which is approved by the FDA for the management of neuropathic pain associated with post-herpetic neuralgia, also known as post-shingles pain; and NP-1998, a Phase 3 ready, prescription strength capsaicin topical solution, being assessed for the treatment of neuropathic pain. NP-1998 was previously referred to as NGX-1998. We made a $7.5 million payment to acquire development and commercialization rights for Qutenza and NP-1998 in the United States, Canada, Latin America and certain other territories. We may also make up to $5.0 million in payments contingent upon the achievement of certain regulatory and sales milestones related to NP-1998.

Astellas Pharma Europe Ltd. has exclusive commercialization rights for Qutenza in the European Economic Area (EEA) including the 28 countries of the European Union, Iceland, Norway, and Liechtenstein as well as Switzerland, certain countries in Eastern Europe, the Middle East and Africa. Astellas also has an option to develop NP-1998 in those same territories.

Qutenza is a dermal patch containing 8% prescription strength capsaicin that can last up to three months and is approved for the management of neuropathic pain associated with post-herpetic neuralgia. The drug was approved by the FDA in 2010 and launched in April 2010 but NeurogesX discontinued active promotion of the product in March 2012. Net product revenue of Qutenza was $209,000 for the three months ended March 31, 2014. In January 2014, we re-launched Qutenza using our existing commercial organization, including our specialty neurology sales force.

NP-1998 is a topical solution containing 20% prescription strength capsaicin. We believe this liquid formulation of the capsaicin-based therapy has key advantages over the patch, and we are currently designing a plan to expedite development of this product as both a stand-alone therapy and as an adjunct to existing systemic therapies for neuropathic pain. NP-1998 has the potential to treat multiple neuropathies. We are planning to pursue HIV-related neuropathy as the first indication for NP-1998, and we are also exploring the potential for additional indications, including painful diabetic neuropathy. In 2014, we are expecting to receive data from a clinical trial being conducted by Astellas to assess the use of its capsaicin (8%) cutaneous patch QUTENZA™ in the treatment of pain associated with painful diabetic neuropathy, or PDN. While the patch and NP-1998 are different products, they contain the same active ingredient, capsaicin, so the results of this Astellas trial may help inform our evaluation of a potential development plan for NP-1998 to treat painful diabetic neuropathy. Also, in February 2014, Astellas presented data from its ELEVATE study at the 14th Asian Australasian Congress of Anesthesiologists, which compared its capsaicin (8%) cutaneous patch QUTENZA™ to an oral therapy widely used to treat various neuropathic pain conditions. This open label study compared efficacy, tolerability, and safety, and the data may be useful in connection with our development plans for NP-1998.

Research & Development Programs

We are developing what we believe is one of the industry’s leading pipelines of novel neurological therapies. We are developing Plumiaz (our trade name for Diazepam Nasal Spray), a proprietary nasal spray formulation of diazepam, for the treatment of people with epilepsy who experience cluster seizures, also known as acute repetitive seizures. We are also studying a once-daily formulation of dalfampridine extended release tablets to improve walking in people who suffer from post-stroke deficits. In addition, we have several research and development programs focused on distinct therapeutic approaches to restoring neurologic and/or cardiac function, as follows. We are developing the clinical stage compounds GGF2 for the treatment of heart failure, rHIgM22, a remyelinating monoclonal antibody, for the treatment of MS, and AC105

for acute treatment of SCI. GGF2 is also being investigated in preclinical studies as a treatment for neurological conditions such as stroke and peripheral nerve injury. Chondroitinase, an enzyme that encourages nerve plasticity in the damaged central nervous system, as in SCI, is in preclinical development. We believe these programs for restoring neurologic and/or cardiac function have the potential to be first-in-class therapies, and may be applicable across a number of CNS disorders, including stroke and traumatic brain injury, or TBI, because many of the mechanisms of tissue damage and repair are similar. Our research and development programs also include our recently acquired NP-1998 program, described above.

Plumiaz (diazepam) Nasal Spray

In December 2012, we completed the acquisition of Neuronex, Inc., a privately-held pharmaceutical company developing Plumiaz (our trade name for Diazepam Nasal Spray). Plumiaz is a proprietary nasal spray formulation of diazepam as an acute treatment for selected, refractory patients with epilepsy, on stable regimens of antiepileptic drugs, or AEDs, who experience intermittent bouts of increased seizure activity, also known as cluster seizures or acute repetitive seizures.

In November 2013, we announced that we submitted a New Drug Application, or NDA, filing for Plumiaz to the FDA. Plumiaz was filed under section 505(b)(2) of the Food Drug and Cosmetic Act, referencing data from a therapy previously approved by the FDA (DIASTAT® Rectal Gel) and providing pharmacokinetic data comparing the reference product to Plumiaz. The Company is seeking an indication for Plumiaz in people with epilepsy who experience cluster seizures. In May 2014, the FDA issued a Complete Response Letter, or CRL, for the Plumiaz NDA. We are evaluating the CRL, and expect to work closely with the FDA to address the items outlined in the letter, which will include additional clinical work, and refile the NDA. We are still planning on pursuing the 505(b)(2) pathway as described above. Once we have refiled the NDA, we expect that the FDA will respond to our submission within six months. Based on the requirements noted in the letter, we do not expect Plumiaz to receive FDA approval in 2014.

We have obtained orphan drug designation, which would confer seven years of market exclusivity from the date of approval for diazepam containing drug products for the same indication. We licensed two patent families relating to the clinical formulation for Plumiaz, including a granted U.S. patent that is set to expire in 2029. We anticipate that our current infrastructure can support sales and marketing of this product if it receives FDA approval. We believe this product has the potential to generate peak annual sales significantly higher than $100 million.

Ampyra/Dalfampridine Development Programs

We believe there may be potential for Ampyra to be applied to other indications within MS and also in other neurological conditions. For example, we have conducted a Phase 2 proof-of-concept trial of dalfampridine extended release tablets in post-stroke deficits. This study, which was initiated in 2012, explored the use of dalfampridine in patients who have experienced a stroke at least six (6) months prior to enrollment and who have stabilized with chronic neurologic deficits, which may include impaired walking, motor and sensory function and manual dexterity. Over the first six months following a stroke, patients typically show some degree of spontaneous recovery of function, which may be enhanced by rehabilitation and physical therapy. This trial targeted motor impairments that remain after such recovery. In the study, treatment with dalfampridine extended release was well-tolerated and improved walking, as measured by the Timed 25-Foot Walk test (T25FW). The safety findings in this study were consistent with previous clinical trials and post-marketing experience of dalfampridine-ER (extended release) in MS. Findings from the trial were presented at the American Neurological Association annual meeting in October 2013, and post-hoc analyses were included in a platform presentation in February 2014 at the 2014 International Stroke Conference.

We developed a once-daily, or QD, formulation of dalfampridine pursuant to a development agreement with an external partner. We are planning to move forward with a Phase 3 clinical trial that will assess the use of this QD formulation of dalfampridine as a treatment for post-stroke walking deficits. We met with the FDA in December 2013 and we are integrating FDA design recommendations into the study protocol. As part of the trial design, we are planning to conduct an interim analysis of the trial data, and depending on the outcome of that analysis we may initiate a second pivotal trial prior to the conclusion of the Phase 3 trial. We previously projected that we planned to begin the Phase 3 trial in the second quarter of 2014. However, in April 2014 we announced that initiation of the trial would begin in the second half of 2014 because the developer of the QD formulation informed us of an alcohol dose dumping finding in vitro and we will need to perform a short clinical study to determine whether this also exists in vivo. This clinical study will be conducted in healthy volunteers and is expected to be completed in the third quarter of 2014.

We also are continuing to evaluate possible grants for investigator-initiated studies looking for potential benefits, including in other neurological disorders.

Also, we previously conducted a proof-of-concept clinical study of dalfampridine in adults with cerebral palsy, or CP. The study included a single dose phase primarily intended to evaluate safety and tolerability, and a second multi-dose phase study to evaluate both safety and efficacy. In April 2013 we announced that efficacy from the second phase suggested potential treatment activity on measures of walking and hand strength, but that these data were still being analyzed to determine if they were sufficiently robust to warrant further clinical studies. After a thorough analysis of the study, we concluded that although, there were some signs of biological activity, the data were not strong enough to justify additional clinical development and we will not proceed with additional CP trials.

Glial Growth Factor 2

We have completed our GGF2 Phase 1 clinical trial in heart failure patients. This was a dose-escalating trial designed to test the maximum tolerated single dose, with follow-up assessments at one, three, and six months. In March 2013, we presented three-month data from this clinical trial in a platform presentation at the American College of Cardiology (ACC) annual meeting. These data showed a dose-related improvement in ejection fraction in addition to safety findings. Dose-limiting toxicities were also identified in the highest planned dose cohort including acute liver injury meeting Hy’s Law for drug induced hepatotoxicity. In October 2013, we announced that the first patient was enrolled in the second clinical trial of GGF2. This Phase 1b single-infusion trial in people with heart failure will assess tolerability of three dose levels of GGF2, and also includes assessment of drug-drug interactions and several exploratory measures of efficacy. We voluntarily paused enrollment in this trial in December 2013 pending review of additional preclinical data with the FDA. In April 2014, we announced that we had completed this review and agreed with the FDA that the trial will resume recruitment. We expect to complete this trial in 2015. If we are able to establish a proof of concept for treatment of heart failure through human clinical studies, we may decide to develop the product independently or to enter into a partnership, most likely with a cardiovascular-focused company.

Remyelinating Antibodies

We have a remyelinating antibodies program that we acquired under license from the Foundation for Medical Education and Research, or Mayo Clinic. Studies have demonstrated the ability of this family of antibodies to stimulate repair of the myelin sheath in three different animal models of MS. Some antibodies within this portfolio also stimulate the growth of neurons and may have applications beyond demyelinating disorders. First identified in mice, similar remyelinating antibodies were subsequently identified in human blood samples by Mayo Clinic. rHIgM22 is our lead recombinant human remyelinating antibody. We believe a therapy that could repair myelin sheaths has the potential to restore substantial neurological function to those affected by demyelinating conditions.

In April 2013, we initiated a Phase 1 clinical trial of rHIgM22 to assess the safety and tolerability of rHIgM22 in patients with MS. The study also includes several exploratory efficacy measures. We expect to complete this trial in the first quarter of 2015. We have completed the dose escalation portion of this trial, with no serious or limiting adverse events reported. The second portion of this trial will explore safety, tolerability and efficacy endpoints for six months in additional patients at the two highest doses achieved in the dose escalation portion of the trial. Enrollment in the second portion of this trial is almost complete. We expect to complete our initial analysis of the trial data in early 2015.

AC105

In June 2011, we entered into a License Agreement with Medtronic, Inc. and one of its affiliates, pursuant to which we acquired worldwide development and commercialization rights to certain formulations of magnesium with a polymer such as polyethylene glycol (which we refer to as AC105). Pursuant to the License Agreement, we paid Medtronic an upfront fee of $3 million and are obligated to pay up to an additional $32 million upon the achievement of specified regulatory and development milestones. If we commercialize AC105, we will also be obligated to pay a single-digit royalty on sales. We are studying AC105 as an acute treatment for patients who have suffered SCI. In September 2013, we announced that the first patient was enrolled in a Phase 2 clinical trial evaluating the safety and tolerability of AC105 in people with traumatic SCI. The study also incorporates several exploratory efficacy measures. Recruitment in this trial has been challenging due to several factors, and we are working with the trial centers to address these.

Chondroitinase Program

We are continuing research on the potential use of chondroitinases for the treatment of injuries to the brain and spinal cord, as well as other neurotraumatic indications. The chondroitinase program is in the research and translational development phase and has not yet entered formal preclinical development.

Outlook for 2014

Financial Guidance for 2014

We are providing the following guidance with respect to our 2014 financial performance:

·	We expect 2014 net revenue from the sale of Ampyra to range from $328 million to $335 million.

We expect Zanaflex (tizanidine hydrochloride) and ex-U.S. Fampyra (prolonged-release fampridine tablets) 2014 revenue to be approximately $25 million, which includes net sales of branded Zanaflex products, royalties from ex-U.S. Fampyra and authorized generic tizanidine hydrochloride capsules sales, and $9.1 million in amortized licensing revenue from the $110 million payment we received from Biogen Idec in 2009 for Fampyra ex-U.S. development and commercialization rights.

Research and development (R&D) expenses in 2014 are expected to range from $60 million to $70 million, excluding share-based compensation charges and expenditures related to the potential acquisition of new products or other business development activities. R&D expenses in 2014 related to dalfampridine include a Phase 3 study in post-stroke deficits and sponsorship of investigator-initiated studies. Additional expenses include continued development of Diazepam Nasal Spray and NP-1998, clinical trials for GGF2, rHIgM22 and AC105, as well ongoing preclinical studies.

Selling, general and administrative expenses (SG&A) in 2014 are expected to range from $180 million to $190 million, excluding share-based compensation charges and expenditures related to the potential acquisition of new products or other business development activities. SG&A expense in 2014 includes commercialization expenses for Plumiaz.

We are evaluating the impact of recent events on both R&D and SG&A expenses for 2014, and will provide an update on our next earnings call if there are any changes to guidance.

The range of SG&A and R&D expenditures for 2014 are non-GAAP financial measures because they exclude share-based compensation charges. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, we believe the presentation of these non-GAAP financial measures, when viewed in conjunction with actual GAAP results, provides investors with a more meaningful understanding of our projected operating performance because they exclude non-cash charges that are substantially dependent on changes in the market price of our common stock. We believe that non-GAAP financial measures that exclude share-based compensation charges help indicate underlying trends in our business, and are important in comparing current results with prior period results and understanding expected operating performance. Also, our management uses non-GAAP financial measures that exclude share-based compensation charges to establish budgets and operational goals, and to manage our business and to evaluate its performance.

Development Pipeline Goals

Our planned goals and key initiatives with respect to our pipeline during and beyond 2014 are as follows:

In November 2013, we announced that we submitted an NDA filing for Plumiaz to the FDA. In May 2014, the FDA issued a Complete Response Letter, or CRL, for the Plumiaz NDA. We are evaluating the CRL, and expect to work closely with the FDA to address the items outlined in the letter, which will include additional clinical work, and refile the NDA. Once we have refiled the NDA, we expect that the FDA will respond to our submission within six months. Based on the requirements noted in the letter, we do not expect Plumiaz to receive FDA approval in 2014.

Continue planning for a Phase 3 clinical trial that will assess the use of a once-daily, or QD, formulation of dalfampridine as a treatment for post-stroke walking deficits. We met with the FDA in December 2013 and we are integrating FDA design recommendations into the study protocol. As part of the trial design, we are planning to conduct an interim analysis of the trial data, and depending on the outcome of that analysis we may initiate a second pivotal trial prior to the conclusion of the Phase 3 trial. We previously projected that we planned to begin the Phase 3 trial in the second quarter of 2014. However, in April 2014 we announced that initiation of the trial would begin in the second half of 2014 because the developer of the QD formulation informed us of an alcohol dose dumping

finding in vitro and we will need to perform a short clinical study to determine whether this also exists in vivo. This clinical study will be conducted in healthy volunteers and is expected to be completed in the third quarter of 2014.

Continue to progress our Phase 1 clinical trial of rHIgM22, which we initiated in April 2013. We expect to complete this trial in the first quarter of 2015. We have completed the dose escalation portion of this trial, with no serious or limiting adverse events reported. The second portion of this trial will explore safety, tolerability and efficacy endpoints for six months in additional patients at the two highest doses achieved in the dose escalation portion of the trial. Enrollment in the second portion of this trial is almost complete. We expect to complete our initial analysis of the trial data in early 2015.

Continue to progress our second clinical trial of GGF2, a Phase 1b single-infusion trial in people with heart failure that will assess tolerability of three dose levels of GGF2, and which also includes assessment of drug-drug interactions and several exploratory measures of efficacy. In October 2013, we announced that the first patient was enrolled in this clinical trial. We voluntarily paused enrollment in this trial in December 2013 pending review of additional preclinical data with the FDA. In April 2014, we announced that we had completed this review and agreed with the FDA that the trial will resume recruitment. We expect to complete this trial in 2015.

Continue to progress our AC105 clinical trial, which is evaluating the safety and tolerability of AC105 in people with traumatic SCI, and also incorporates several exploratory efficacy measures. In September 2013, we announced that the first patient was enrolled in this clinical trial. Recruitment in this trial has been challenging due to several factors, and we are working with the trial centers to address these.

Results of Operations

Three-Month Period Ended March 31, 2014 Compared to March 31, 2013

Net Product Revenues

Ampyra

We recognize product sales of Ampyra following shipment of product to our network of specialty pharmacy providers, Kaiser and the specialty distributor to the VA. We recognized net revenue from the sale of Ampyra to these customers of $72.5 million as compared to $62.3 million for the three-month periods ended March 31, 2014 and 2013, respectively, an increase of $10.2 million, or 16.3%. The net revenue increase was comprised of price increases net of discount and allowance adjustments of $5.3 million and net volume increases of $4.9 million. Net revenue from sales of Ampyra increased for the three-month period ended March 31, 2014 compared to the same period of 2013 due to our price increase and greater demand we believe due to, in part, the success of certain marketing programs such as our First Step and Step Together programs. Effective January 2, 2014, we increased our sale price to our customers by 10.75%.

Discounts and allowances which are included as an offset in net revenue consist of allowances for customer credits, including estimated chargebacks, rebates, discounts and returns. Discounts and allowances are recorded following shipment of Ampyra tablets to our network of specialty pharmacy providers, Kaiser and the specialty distributor to the VA. Adjustments are recorded for estimated chargebacks, rebates, and discounts. Discounts and allowances also consist of discounts provided to Medicare beneficiaries whose prescription drug costs cause them to be subject to the Medicare Part D coverage gap (i.e., the “donut hole”). Payment of coverage gap discounts is required under the Affordable Care Act, the health care reform legislation enacted in 2010. Discounts and allowances may increase as a percentage of sales as we enter into managed care contracts in the future.

The net revenue for the three-month period ended March 31, 2014, decreased from net revenue of $84.6 million for the three-month period ended December 31, 2013. We believe that the decrease in net revenue between the fourth quarter of 2013 and the first quarter of 2014 reflects certain recurring seasonal factors relating to the commencement of a new calendar year. These factors include people switching insurance plans or pharmacy benefit providers at year-end. Consequently, many patients have to re-establish eligibility during the first few months of the calendar year. Also, when deductibles and the Medicare donut hole reset at the beginning of the calendar year, it can affect timely refills for consumers with financial constraints. In addition, as in previous years, there was some inventory build in the fourth quarter of 2013 that was destocked during the first quarter.

Zanaflex

We recognize product sales of Zanaflex Capsules and Zanaflex tablets using a deferred revenue recognition model where shipments to wholesalers are recorded as deferred revenue and only recognized as revenue when end-user prescriptions of the product are reported. We also recognize product sales on the transfer price of product sold for an authorized generic of Zanaflex Capsules. We recognized net revenue from the sale of Zanaflex Capsules and Zanaflex tablets of $900,000 for the three-month period ended March 31, 2014, as compared to $1.3 million for the three-month period ended March 31, 2013. Net product revenues also include $830,000 which represents the sale of our Zanaflex Capsules authorized generic product to Actavis for the three-month period ended March 31, 2014 as compared to $493,000 for the three-month period ended March 31, 2013. Generic competition has caused a significant decline in sales of Zanaflex Capsules and is expected to cause the Company’s net revenue from Zanaflex Capsules to decline further in 2014 and beyond. The decrease in net revenues was also the result of a disproportionate increase in discounts and allowances due to the mix of customers continuing to purchase our product. These customers receive higher levels of rebates and allowances.

Discounts and allowances, which are included as an offset in net revenue, consist of allowances for customer credits, including estimated chargebacks, rebates, and discounts. Adjustments are recorded for estimated chargebacks, rebates, and discounts.

Qutenza

We started selling Qutenza in July 2013 as a result of the NeurogesX transaction. We recognize product sales of Qutenza following shipment of product to our specialty distributors. We recognized net revenue from the sale of Qutenza to these customers of $209,000 for the three-month period ended March 31, 2014. For the foreseeable future we do not expect that sales of this product will materially contribute to our revenues.

License Revenue

We recognized $2.3 million in license revenue for the three-month periods ended March 31, 2014 and 2013, related to the $110.0 million received from Biogen Idec in 2009 as part of our collaboration agreement. We currently estimate the recognition period to be approximately 12 years from the date of the Collaboration Agreement.

Royalty Revenue

We recognized $2.4 million and $2.9 million in royalty revenue for the three-month periods ended March 31, 2014 and 2013, respectively, related to ex-U.S. sales of Fampyra by Biogen Idec. 2013 included a favorable adjustment of $1.0 million from the establishment of pricing in Germany. In 2011, the German government implemented new legislation to manage pricing related to new drug products introduced within the German market through a review of each product’s comparative efficacy. Biogen Idec launched Fampyra in Germany in August 2011. During the three-month period ended June 30, 2012, the government agency completed its comparative efficacy assessment of Fampyra indicating a range of pricing below Biogen Idec’s initial launch price, which was unregulated for the first 12 months after launch consistent with German law. The Company recognized royalty revenue during a portion of 2012 based on the lowest point of the initially indicated German pricing authority range. The Company began recognizing royalty revenue at the negotiated fixed price effective upon the signing of Biogen Idec’s pricing agreement in the first quarter of 2013.

We recognized $1.4 million and $2.6 million in royalty revenue for the three-month periods ended March 31, 2014 and 2013, respectively, related to the authorized generic sale of Zanaflex Capsules which started in February 2012.

Cost of Sales

We recorded cost of sales of $15.5 million for the three-month period ended March 31, 2014 as compared to $13.5 million for the three-month period ended March 31, 2013. Cost of sales for the three-month period ended March 31, 2014 consisted primarily of $12.7 million in inventory costs related to recognized revenues. Cost of sales for the three-month period ended March 31, 2014 also consisted of $1.7 million in royalty fees based on net product shipments, $179,000 in amortization of intangible assets, and $88,000 in period costs related to freight, stability testing, and packaging. Cost of sales also included $830,000, which represents the cost of Zanaflex Capsules authorized generic product sold for the three-month period ended March 31, 2014.

Cost of sales for the three-month period ended March 31, 2013 consisted primarily of $11.1 million in inventory costs related to recognized revenues. Cost of sales for the three-month period ended March 31, 2013 also consisted of $1.7

million in royalty fees based on net product shipments, $147,000 in amortization of intangible assets, and $63,000 in period costs related to freight, stability testing, and packaging. Cost of sales also included $493,000, which represents the cost of Zanaflex Capsules authorized generic product sold for the three-month period ended March 31, 2013.

Cost of License Revenue

We recorded cost of license revenue of $159,000 for the three-month periods ended March 31, 2014 and 2013, respectively. Cost of license revenue represents the recognition of a portion of the deferred $7.7 million paid to Alkermes in 2009 in connection with the $110.0 million received from Biogen Idec as a result of our collaboration agreement.

Research and Development

Research and development expenses for the three-month period ended March 31, 2014 were $14.5 million as compared to $12.5 million for the three-month period ended March 31, 2013, an increase of approximately $2.0 million, or 16%. The increase was primarily due to an increase of $1.0 million for current year research and development expenses related to Plumiaz, an increase of $887,000 in expenses for the remyelinating antibodies program (rHIgM22), and an increase in overall research and development staff, compensation and related expenses of $540,000 to support the various research and development initiatives related to our product pipeline. The increases in research and development expenses for the three-month period ended March 31, 2014 were partially offset by a decrease of $709,000 related to our life cycle management program for Ampyra due to timing.

Selling, General and Administrative

Sales and marketing expenses for the three-month period ended March 31, 2014 were $26.6 million compared to $29.5 million for the three-month period ended March 31, 2013, a decrease of approximately $2.9 million, or 10%. The decrease was attributable to a decrease in overall marketing, selling, distribution, and market research expenses for Ampyra of $3.8 million. The decrease in sales and marketing expenses was partially offset by an increase of $1.0 million for pre-launch activities associated with the possible commercialization of Plumiaz.

General and administrative expenses for the three-month period ended March 31, 2014 were $20.3 million compared to $18.7 million for the three-month period ended March 31, 2013, an increase of approximately $1.6 million, or 9%. This increase was primarily the result of an increase of $1.8 million for staff and compensation expenses and other expenses related to supporting the growth of the organization and an increase of $1.0 million for work on FDA post-approval requirements for the Zanaflex franchise. The increases in general and administrative expenses for the three-month period ended March 31, 2014 were partially offset by a decrease of $980,000 in safety and surveillance expenses.

Other Income / Expense

Other income was $80,000 for the three-month period ended March 31, 2014 compared to other expense of $418,000 for the three-month period ended March 31, 2013, a decrease of approximately $498,000, or 119%. The decrease was due to a decrease in interest expense of $498,000 principally related to the PRF revenue interest agreement due to a decrease in Zanaflex sales.

Provision for Income Taxes

We continue to evaluate the realizability of the Company’s deferred tax assets and liabilities on a periodic basis and will adjust such amounts in light of changing facts and circumstances including, but not limited to, future projections of taxable income, tax legislation, rulings by relevant tax authorities, the progress of ongoing tax audits and the regulatory approval of products currently under development. Any changes to the valuation allowance or deferred tax assets in the future would impact the Company's income taxes.

Liquidity and Capital Resources

Since our inception, we have financed our operations primarily through private placements and public offerings of our common stock and preferred stock, payments received under our collaboration and licensing agreements, sales of Ampyra and Zanaflex Capsules, and, to a lesser extent, from loans, government grants and our financing arrangement with PRF.

We were cash flow positive in 2013 and, at March 31, 2014, we had $372.2 million of cash, cash equivalents and short-term and long-term investments, compared to $367.2 million at December 31, 2013. Any investments classified as long-term had maturity dates of no later than July 31, 2015. We believe that we have sufficient cash, cash equivalents, short-term and long-term investments on hand, in addition to cash expected to be generated from operations, to fund our 2014 business plan, including our currently anticipated development pipeline activities in 2014.

Our future capital requirements will depend on a number of factors, including the amount of revenue generated from sales of Ampyra, the continued progress of our research and development activities, the amount and timing of milestone or other payments payable under collaboration, license and acquisition agreements, the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims and other intellectual property rights, and the extent to which we acquire or in-license new products and compounds including the development costs relating to those products or compounds. To the extent our capital resources are insufficient to meet future operating requirements we will need to raise additional capital, reduce planned expenditures, or incur indebtedness to fund our operations. If we require additional financing in the future, we cannot assure you that it will be available to us on favorable terms, or at all.

Financing Arrangements

In January 1997, Elan International Services, Ltd. (EIS) loaned us an aggregate of $7.5 million pursuant to two convertible promissory notes to partly fund our research and development activities. On December 23, 2005, Elan transferred these promissory notes to funds affiliated with Saints Capital. As of March 31, 2014, $3.3 million of these promissory notes was outstanding, which amount includes accrued interest. The fourth of seven annual payments on this note was due and paid on the four year anniversary of Ampyra approval on January 22, 2014 and will continue to be paid annually until paid in full.

On December 23, 2005, we entered into a revenue interest assignment agreement with PRF, a dedicated healthcare investment fund, pursuant to which we assigned to PRF the right to a portion of our net revenues (as defined in the agreement) from Zanaflex Capsules, Zanaflex tablets and any future Zanaflex products including the authorized generic version of Zanaflex Capsules being sold by Watson effective in February 2012. To secure our obligations to PRF, we also granted PRF a security interest in substantially all of our assets related to Zanaflex. Our agreement with PRF covers all Zanaflex net revenues generated from October 1, 2005 through and including December 31, 2015, including the authorized generic version of Zanaflex Capsules revenue, unless the agreement terminates earlier. In November 2006, we entered into an amendment to the revenue interest assignment agreement with PRF. Under the terms of the amendment, PRF paid us $5.0 million in November 2006. An additional $5.0 million was due to us if net revenues during the fiscal year 2006 equaled or exceeded $25.0 million. This milestone was met and the receivable was reflected in our December 31, 2006 financial statements. Under the terms of the amendment, we repaid PRF $5.0 million on December 1, 2009 and an additional $5.0 million on December 1, 2010 since the net revenues milestone was met.

Under the agreement and the amendment, PRF is entitled to the following portion of Zanaflex net revenues:

•

with respect to Zanaflex net revenues up to and including $30.0 million for each fiscal year during the term of the agreement, 15% of such net revenues;

•

with respect to Zanaflex net revenues in excess of $30.0 million but less than and including $60.0 million for each fiscal year during the term of the agreement, 6% of such net revenues; and

•

with respect to Zanaflex net revenues in excess of $60.0 million for each fiscal year during the term of the agreement, 1% of such net revenues.

Notwithstanding the foregoing, once PRF has received and retained payments under the agreement that are at least 2.1 times the aggregate amount PRF has paid us under the agreement, PRF will only be entitled to 1% of Zanaflex net revenues. In connection with the transaction, we recorded a liability as of March 31, 2014, referred to as the revenue interest liability, of approximately $0.8 million. We impute interest expense associated with this liability using the effective interest

rate method and record a corresponding accrued interest liability. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the life of the arrangement. The interest rate on this liability may vary during the term of the agreement depending on a number of factors, including the level of Zanaflex sales. We currently estimate that the imputed interest rate associated with this liability will be approximately 5.7%. Payments made to PRF as a result of Zanaflex sales levels will reduce the accrued interest liability and the principal amount of the revenue interest liability.

Upon the occurrence of certain events, including if we experience a change of control, undergo certain bankruptcy events, transfer any of our interests in Zanaflex (other than pursuant to a license agreement, development, commercialization, co-promotion, collaboration, partnering or similar agreement), transfer all or substantially all of our assets, or breach certain of the covenants, representations or warranties we make under the agreement, PRF may (i) require us to repurchase the rights we sold them at the “put/call price” in effect on the date such right is exercised or (ii) foreclose on the Zanaflex assets that secure our obligations to PRF. Except in the case of certain bankruptcy events, if PRF exercises its right, which we refer to as PRF’s put option, to cause us to repurchase the rights we assigned to it, PRF may not foreclose unless we fail to pay the put/call price as required. If we experience a change of control we have the right, which we refer to as our call option, to repurchase the rights we sold to PRF at the “put/call price” in effect on the date such right is exercised. The put/call price on a given date is the greater of (i) all payments made by PRF to us as of such date, less all payments received by PRF from us as of such date, and (ii) an amount that would generate an internal rate of return to PRF of 25% on all payments made by PRF to us as of such date, taking into account the amount and timing of all payments received by PRF from us as of such date. We have determined that PRF’s put option and our call option meet the criteria to be considered an embedded derivative and should be accounted for as such. Therefore, we recorded a net liability of $167,000 as of March 31, 2014 related to the put/call option to reflect its current estimated fair value. This liability is revalued on an as needed basis to reflect any changes in the fair value and any gain or loss resulting from the revaluation is recorded in earnings.

During any period during which PRF has the right to receive 15% of Zanaflex net revenues (as defined in the agreement), then 8% of the first $30.0 million in payments from Zanaflex sales we receive from wholesalers will be distributed to PRF on a daily basis. Following the end of each fiscal quarter, if the aggregate amount actually received by PRF during such quarter exceeds the amount of net revenues PRF was entitled to receive, PRF will remit such excess to us. If the amount of net revenues PRF was entitled to receive during such quarter exceeds the aggregate amount actually received by PRF during such quarter, we will remit such excess to PRF.

On August 3, 2012, we received a letter from PRF alleging that we breached specified covenants and representations in the PRF agreement and purporting to exercise the put option. The letter also includes an allegation that PRF has suffered injuries beyond what is covered by their purported exercise of the put option, although it does not specify or quantify those injuries. We believe that the allegations are without merit and that the put option has not been validly exercised. Although the letter from PRF does not include a purported calculation of the put option price, if it were validly exercised, we estimate that the incremental cost to the Company in excess of amounts already accrued to PRF at March 31, 2014 would be no more than approximately $1.7 million.

Investment Activities

At March 31, 2014, cash, cash equivalents, short-term and long-term investments were approximately $372.2 million, as compared to $367.2 million at December 31, 2013. Our cash and cash equivalents consist of highly liquid investments with original maturities of three months or less at date of purchase and consist of time deposits and investments in a Treasury money market fund and US Treasury bonds. Also, we maintain cash balances with financial institutions in excess of insured limits. We do not anticipate any losses with respect to such cash balances. As of March 31, 2014, our cash and cash equivalents were $44.4 million, as compared to $48.0 million as of December 31, 2013. Our short-term investments consist of US Treasury bonds with original maturities greater than three months and less than one year. The balance of these investments was $226.1 million as of March 31, 2014, as compared to $225.9 million as of December 31, 2013. Our long-term investments consist of US Treasury bonds with original maturities greater than one year. The balance of these investments was $101.7 million as of March 31, 2014, as compared to $93.3 million as of December 31, 2013.

Net Cash Provided by / (Used in) Operations

Net cash provided by operations was $4.3 million for the three-month period ending March 31, 2014 while $7.7 million was used in the three-month period ended March 31, 2013. Cash provided by operations for the three-month period ended March 31, 2014 was primarily due to a non-cash share-based compensation expense of $5.8 million, a deferred tax provision of $2.8 million, depreciation and amortization of $1.8 million, and net income of $703,000 principally resulting from an increase in net product revenues. Cash provided by operations was partially offset by a net decrease in working

capital items of $5.4 million attributable to an increase in inventory held by the company and a decrease in accounts payable resulting from payment timing.

Cash used in operations for the three-month period ended March 31, 2013 was primarily due to a decrease in working capital items of $9.5 million attributable to an increase in inventory held by the company and payment of accrued and prepaid items partially offset by a decrease in accounts receivable. Cash used in operations was also attributable to a decrease in non-current portion of deferred license revenue of $2.3 million, a deferred tax benefit of $1.8 million, and a net loss of $1.1 million principally resulting from an overall increase in operating expenses. Cash used in operations was partially offset by a non-cash share-based compensation expense of $4.9 million, amortization of net premiums and discounts on investments of $590,000 and depreciation and amortization of $1.4 million.

Net Cash Used in Investing

Net cash used in investing activities for the three-month period ended March 31, 2014 was $11.4 million, primarily due to $93.8 million in purchases of investments, purchases of intangible assets of $1.2 million, and purchases of property and equipment of $942,000, partially offset by $84.5 million in proceeds from maturities and sales of investments.

Net Cash Provided by Financing

Net cash provided by financing activities for the three-month period ended March 31, 2014 was $3.5 million, primarily due to $3.7 million in net proceeds from the issuance of common stock and exercise of stock options partially offset by $212,000 in repayments to PRF.

Contractual Obligations and Commitments

A summary of our minimum contractual obligations related to our major outstanding contractual commitments is included in our Annual Report on Form 10-K for the year ended December 31, 2013. Our long-term contractual obligations include commitments and estimated purchase obligations entered into in the normal course of business. Under certain supply agreements and other agreements with manufacturers and suppliers, we are required to make payments for the manufacture and supply of our clinical and approved products. During the three-month period ended March 31, 2014, commitments related to the purchase of inventory increased as compared to December 31, 2013. As of March 31, 2014, we have inventory-related purchase commitments totaling approximately $27.7 million.

Under certain agreements, we are required to pay royalties for the use of technologies and products in our R&D activities and in the commercialization of products. The amount and timing of any of the foregoing payments are not known due to the uncertainty surrounding the successful research, development and commercialization of the products.

Under certain agreements, we are also required to pay license fees and milestones for the use of technologies and products in our R&D activities and in the commercialization of products. As of March 31, 2014, we have committed to make potential future milestone payments to third parties of up to approximately $206 million as part of our various collaborations, including licensing and development programs. Payments under these agreements generally become due and payable only upon achievement of certain developmental, regulatory or commercial milestones. Because the achievement of these milestones had not occurred as of March 31, 2014, such contingencies have not been recorded in our financial statements. Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent on the successful achievement of certain development, regulatory and commercial milestones. There is uncertainty regarding the various activities and outcomes needed to reach these milestones, and they may not be achieved.

Critical Accounting Policies and Estimates

Our critical accounting policies are detailed in our Annual Report on Form 10-K for the year ended December 31, 2013. As of March 31, 2014, our critical accounting policies have not changed materially from December 31, 2013.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our financial instruments consist of cash equivalents, short-term and long-term investments, grants receivable, convertible notes payable, accounts payable, and put/call liability. The estimated fair values of all of our financial instruments approximate their carrying amounts at March 31, 2014.

We have cash equivalents, short-term and long-term investments at March 31, 2014, which are exposed to the impact of interest rate changes and our interest income fluctuates as our interest rates change. Due to the nature of our investments in money market funds and US Treasury bonds, the carrying value of our cash equivalents and short-term and long-term investments approximate their fair value at March 31, 2014. Our investments designated as long-term as of March 31, 2014 had maturity dates no later than July 31, 2015. At March 31, 2014, we held $372.2 million in cash, cash equivalents, short-term and long-term investments which had an average interest rate of approximately 0.2%.

We maintain an investment portfolio in accordance with our investment policy. The primary objectives of our investment policy are to preserve principal, maintain proper liquidity and to meet operating needs. Although our investments are subject to credit risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer or type of investment. Our investments are also subject to interest rate risk and will decrease in value if market interest rates increase. However, due to the conservative nature of our investments and relatively short duration, interest rate risk is mitigated. We do not own derivative financial instruments. Accordingly, we do not believe that there is any material market risk exposure with respect to derivative or other financial instruments.

Item 4. Controls and Procedures

Evaluation of disclosure controls and procedures

As required by Rule 13a-15 under the Securities Exchange Act of 1934 (the “Exchange Act”) we carried out an evaluation of the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the first quarter of 2014, the period covered by this report. This evaluation was carried out under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer. Based on that evaluation, these officers have concluded that, as of March 31, 2014, our disclosure controls and procedures were effective to achieve their stated purpose.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules, regulations, and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding disclosure.

Change in internal control over financial reporting

In connection with the evaluation required by Exchange Act Rule 13a-15(d), our management, including our chief executive officer and chief financial officer, concluded that there were no changes in our internal control over financial reporting during the quarter ended March 31, 2014, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the effectiveness of controls

Our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met. Because of inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

In August 2007, we received a Paragraph IV Certification Notice from Apotex Inc., advising that it had submitted an Abbreviated New Drug Application, or ANDA, to the FDA seeking marketing approval for generic versions of Zanaflex Capsules. In response to the filing of the ANDA, in October 2007, we filed a lawsuit against Apotex in the U.S. District Court for the District of New Jersey asserting infringement of our U.S. Patent No. 6,455,557. In September 2011, the Court ruled against us and, following our appeal, in June 2012 the U.S. Court of Appeals for the Federal Circuit affirmed the decision. We did not seek any further appeal of the decision. On September 6, 2011, we filed a citizen petition with the FDA requesting that the FDA not approve Apotex’s ANDA because of public-safety concerns about Apotex’s proposed drug. On December 2, 2011, Apotex filed suit against us in the U.S. District Court for the Southern District of New York. In that suit, Apotex alleged, among other claims, that we engaged in anticompetitive behavior and false advertising in connection with the development and marketing of Zanaflex Capsules, including that the citizen petition we filed with the FDA delayed FDA approval of Apotex’s generic tizanidine capsules. On January 26, 2012, we moved to dismiss or stay Apotex’s suit. On February 3, 2012, the FDA denied the citizen petition that we filed and approved Apotex’s ANDA for a generic version of Zanaflex Capsules. On February 21, 2012, Apotex filed an amended complaint that incorporated the FDA action, but otherwise made allegations similar to the original complaint. Requested judicial remedies include monetary damages, disgorgement of profits, recovery of litigation costs, and injunctive relief. Following our filing of a motion to dismiss the amended complaint, in 2013 the Court dismissed five of the six counts in the amended complaint, including all of the antitrust claims, leaving only a claim under the Lanham Act relating to alleged product promotional activities. The case is now proceeding, and the Company intends to defend itself vigorously in the litigation.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the risk factors discussed in Part I, Item 1A. Risk Factors, in our Annual Report on Form 10-K for the year ended December 31, 2013, all of which could materially affect our business, financial condition or future results. These risks are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.
