(1) Organization and Business Activities
 
Acorda Therapeutics, Inc. (“Acorda” or the “Company”) is a commercial stage biopharmaceutical company dedicated to the identification, development and commercialization of novel therapies that improve neurological function in people with multiple sclerosis (MS), spinal cord injury and other disorders of the central nervous system.
 
The management of the Company is responsible for the accompanying audited consolidated financial statements and the related information included in the notes to the consolidated financial statements. In the opinion of management, the audited 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.
 
The Company finances its operations through a combination of issuance of equity securities, revenues from Ampyra and Zanaflex Capsules, loans, collaborations and, to a lesser extent, grants. There are no assurances that the Company will be successful in obtaining an adequate level of financing needed to fund its development and commercialization efforts. To the extent the Company’s capital resources are insufficient to meet future operating requirements, the Company will need to raise additional capital, reduce planned expenditures, or incur indebtedness to fund its operations. The Company may be unable to obtain additional debt or equity financing on acceptable terms, if at all. If adequate funds are not available, the Company may be required to curtail its sales and marketing efforts, delay, reduce the scope of or eliminate some of its research and development programs or obtain funds through arrangements with collaborative partners or others that may require us to relinquish rights to certain product candidates that it might otherwise seek to develop or commercialize independently.
 
Summary of Significant Accounting Policies
Summary of Significant Accounting Policies
(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 inventory value based on an estimate of Zanaflex inventory value based on an estimate of inventory that may be returned. Actual results could differ from those estimates.
 
Cash and Cash Equivalents
 
The Company considers all highly liquid debt instruments with original maturities of three months or less from date of purchase to be cash equivalents. All cash and cash equivalents are held in highly rated securities including a Treasury money market fund and US Treasury bonds, which are unrestricted as to withdrawal or use. To date, the Company has not experienced any losses on its cash and cash equivalents. The carrying amount of cash and cash equivalents approximates its fair value due to its short-term and liquid nature.
 
Restricted Cash
 
Restricted cash represents a certificate of deposit placed by the Company with a bank for issuance of a letter of credit to the Company’s lessor for office space.
 
Short-Term Investments
 
Short-term investments consist of US Treasury bonds with maturities greater than three months. The Company classifies its short-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.
 
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.
 
Inventory
 
     Inventory is stated at the lower of cost or market value and includes amounts for Ampyra, Zanaflex tablet and Zanaflex Capsule inventories and is recorded at its net realizable value. Inventories consist of finished goods inventory. Cost is determined using the first-in, first-out method (FIFO) for all inventories. The Company adjusts its inventory value based on an estimate of inventory that may be returned or not sold based on sales projections and establishes reserves as necessary for obsolescence and excess inventory.
 
Ampyra
 
Prior to regulatory approval of Ampyra, the Company incurred expenses for the manufacture of bulk, unpackaged product of Ampyra that ultimately became available to support the commercial launch of this drug candidate. Until the necessary initial regulatory approval was received, we charged all such amounts to research and development expenses as there was no alternative future use prior to regulatory approval. As a result, our initial sales of Ampyra resulted in higher gross margins than if the inventory costs had not previously been expensed. Upon regulatory approval of Ampyra, the Company began capitalizing the commercial inventory costs associated with manufacturing with Elan and its second manufacturer, Patheon.
 
    The cost of Ampyra inventory manufactured by Elan is based on specified prices calculated as a percentage of net product sales of the product shipped by Elan to Acorda. In the event Elan does not manufacture the products, Elan is entitled to a compensating payment for the quantities of product provided by the alternative manufacturer. This compensating payment is included in the Company’s inventory balances.

 
Property and Equipment
 
Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed on the straight-line basis over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are recorded at cost, less accumulated amortization, which is computed on the straight-line basis over the shorter of the useful lives of the assets or the remaining lease term. Expenditures for maintenance and repairs are charged to expense as incurred.
 
Intangible Assets
 
The Company has recorded intangible assets related to milestones for Ampyra as well as its Zanaflex acquisition and for certain website development costs. These intangible assets are amortized on a straight line basis over the period in which the Company expects to receive economic benefit and are reviewed for impairment when facts and circumstances indicate that the carrying value of the asset may not be recoverable. The determination of the expected life will be dependent upon the use and underlying characteristics of the intangible asset. In the Company’s evaluation of the intangible assets, it considers the term of the underlying asset life and the expected life of the related product line. If the carrying value is not recoverable, impairment is measured as the amount by which the carrying value exceeds its estimated fair value. Fair value is generally estimated based on either appraised value or other valuation techniques.
 
Impairment of Long-Lived Assets
 
The Company continually evaluates whether events or circumstances have occurred that indicate that the estimated remaining useful life of its long-lived assets may warrant revision or that the carrying value of these assets may be impaired. The Company evaluates the realizability of its long-lived assets based on profitability and cash flow expectations for the related assets. Any write-downs are treated as permanent reductions in the carrying amount of the assets. Based on this evaluation, the Company believes that, as of each of the balance sheet dates presented, none of the Company’s long-lived assets were impaired.
 
Patent Costs
 
Patent application and maintenance costs are expensed as incurred.
 
Research and Development
 
Research and development expenses include the costs associated with the Company’s internal research and development activities including, salaries and benefits, occupancy costs, and research and development conducted for it by third parties, such as sponsored university-based research, clinical trials, contract manufacturing for its preclinical program, and regulatory expenses.  In addition, research and development expenses include the cost of clinical trial drug supply shipped to the Company’s clinical study vendors. The Company accounts for its clinical study costs by estimating the patient cost per visit in each clinical trial and recognize this cost as visits occur, beginning when the patient enrolls in the trial. This estimated cost includes payments to the trial site and patient-related costs, including laboratory costs related to the conduct of the trial. Cost per patient varies based on the type of clinical trial, the site of the clinical trial, and the length of the treatment period for each patient. As actual costs become known to the Company, it adjusts the accrual; such changes in estimate may be a material change in its clinical study accrual, which could also materially affect its results of operations. All research and development costs are expensed as incurred except when accounting for nonrefundable advance payments for goods or services to be used in future research and development activities.  These payments are capitalized at the time of payment and expensed ratably over the period the research and development activity is performed.
 
Accounting for Income Taxes
 
Income taxes are accounted for under the asset and liability method with deferred tax assets and liabilities recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be reversed or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance for the amounts of any tax benefits which, more likely than not, will not be realized.
 
    In determining whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits, a two-step process is utilized whereby the threshold for recognition is a more likely-than-not test that the tax position will be sustained upon examination and the tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The Company has no reserves for uncertain tax positions.

Revenue Recognition

Ampyra

Ampyra is available only through a network of specialty pharmacy providers that provide the medication to patients by mail and Kaiser Permanente (Kaiser). Ampyra will not be available in retail pharmacies. The Company applies the revenue recognition guidance in Staff Accounting Bulletin (SAB) 104 and 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 and Kaiser. As of December 31, 2010, inventory levels at specialty pharmacy providers that distribute Ampyra (excluding Kaiser) represented approximately two weeks of their anticipated usage. The specialty pharmacy providers and Kaiser are contractually obligated to hold no more than 30 days of inventory.

The Company’s net revenues represent total revenues less allowances for customer credits, including estimated rebates, discounts 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 to specialty pharmacies and Kaiser, an adjustment is recorded for estimated rebates, discounts 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, discounts and returns are established based on the contractual terms with customers, 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.

Based on the Company’s specialty distribution model where it sells to only 12 specialty pharmacies and Kaiser, the inventory and prescription data it receives from these distributors, and returns experience of other specialty products with similar selling models, the Company has been able to make a reasonable estimate for product returns. At December 31, 2010, inventory levels at the specialty pharmacies (excluding Kaiser) represented approximately two weeks of their anticipated usage. The Company will accept returns of Ampyra for two months prior to and six months after the product expiration date. The Company will provide a credit for such returns to customers with whom we have a direct relationship. Once product is prescribed, it cannot be returned. The Company does not exchange product from inventory for the returned product.

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 was 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.
 
    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, should be characterized as a reduction of revenue when recognized in the vendor’s statement of operations. Adjustments are recorded for 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.
 
Milestones and royalties
 
Revenue from milestones is recognized when earned, as evidenced by written acknowledgement from the other party to a contract, provided that (i) the milestone event is substantive, its achievability was not reasonably assured at the inception of the agreement, and the Company has no further performance obligations relating to that event, and (ii) collectability is reasonably assured. If these criteria are not met, the milestone payment is recognized over the remaining period of our performance obligations under the arrangement. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements.
 
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 Risk
 
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of investments in cash and cash equivalents, restricted cash and accounts receivable. The Company maintains cash and cash equivalents and restricted cash with approved financial institutions. The Company is exposed to credit risks and liquidity in the event of default by the financial institutions or issuers of investments in excess of FDIC insured limits. The Company performs periodic evaluations of the relative credit standing of these financial institutions and limits the amount of credit exposure with any institution.
 
The Company is substantially dependent upon Elan for several activities related to the development and commercialization of Ampyra. The Company and Elan rely on a single third-party manufacturer to supply dalfampridine, the active pharmaceutical ingredient in Ampyra. Under the Company’s supply agreement with Elan, the Company is obligated to purchase at least 75% of its yearly supply of Ampyra from Elan, and the Company is required to make compensatory payments if it does not purchase 100% of its requirements from Elan, subject to certain exceptions. The Company and Elan have agreed that it may purchase up to 25% of its annual requirements from Patheon, a mutually agreed-upon second manufacturing source, with compensatory payment.
 
The Company currently relies on Elan to supply it with Zanaflex Capsules under its 2004 Supply Agreement. The initial term of the agreement expired in 2009, but is subject to two automatic two-year renewal terms. Either party may terminate the agreement by notifying the other party at least 12 months prior to the expiration of the initial term or any renewal term. In addition, either party may terminate the agreement if the other party commits a material breach that remains uncured. If a failure to supply occurs under the agreement, other than a force majeure event, or if the Company terminates the supply agreement for cause, Elan must use commercially reasonable efforts to assist the Company in transferring production of Zanaflex Capsules to it or a third-party manufacturer, provided that such third party is not a technological competitor of Elan. If the Company needs to transfer production, Elan has agreed to grant it a royalty-free, fully paid-up license of its manufacturing know-how and other information and rights related to the production of Zanaflex Capsules, including a license to use its proprietary technology for specified purposes. The Company has the right to sublicense this know-how to a third party manufacturer, provided that this third party is not a technological competitor of Elan. In the event of termination of the supply agreement due to a force majeure event that continues for more than three months, Elan has agreed to enter into negotiations with the Company to preserve the continuity of supply of products, including the possibility of transferring manufacturing of Zanaflex Capsules to it or a third party manufacturer.
 
Prior to March 2007, the Company relied on a single manufacturer, Novartis, for the supply of tizanidine hydrochloride, the active pharmaceutical ingredient (API) in Zanaflex tablets. Novartis discontinued production of tizanidine hydrochloride and will no longer supply it. Therefore, the Company is required to obtain FDA approval for a new supplier of the tizanidine hydrochloride needed for the production of Zanaflex tablets. The Company has identified a potential new supplier and it is seeking the required FDA approval.  The Company expects to complete this process during the second quarter of 2011.  Elan has supplied it with some Novartis-manufactured tizanidine hydrochloride, and based on current sales forecasts the Company believes it will have qualified its new supplier before its current inventory is depleted.  However, it cannot obtain any more tizanidine hydrochloride for Zanaflex tablets from Elan. If the Company fails to gain FDA approval of its new tizanidine hydrochloride supplier, or if there is an unexpected delay in obtaining that approval, it may run out of inventory of tizanidine hydrochloride for Zanaflex tablets.  The Company could also run out of inventory if, prior to qualifying its new supplier, sales of Zanaflex tablets are higher than its current forecasts.  If the Company cannot manufacture enough Zanaflex tablets to meet demand, its sales of Zanaflex tablets would suffer.
 
The Company is currently in contract negotiations with Patheon regarding the manufacture of Zanaflex tablets, and Patheon has agreed to manufacture Zanaflex tablets prior to the contract being executed. If either Elan or Patheon experiences any disruption in their operations, a delay or interruption in the supply of its Zanaflex products could result until the affected supplier cures the problem or the Company locates an alternate source of supply. The Company may not be able to enter into alternative supply arrangements on terms that are commercially favorable, if at all. Any new supplier would also be required to qualify under applicable regulatory requirements. The Company could experience substantial delays before it is able to qualify any new supplier and transfer the required manufacturing technology to that supplier.
 
The Company’s principal direct customers as of December 31, 2010 were a network of specialty pharmacies and Kaiser for Ampyra and wholesale pharmaceutical distributors for Zanaflex Capsules and Zanaflex tablets. The Company periodically assesses the financial strength of these customers and establishes allowances for anticipated losses, if necessary. To date, such losses have been minimal.
 
Allowance for Doubtful Accounts
 
A portion of the Company’s accounts receivable may not be collected due principally to customer disputes and sales returns. The Company provides reserves for these situations based on the evaluation of the aging of its trade receivable portfolio and an analysis of high-risk customers. The Company has not recognized an allowance as of December 31, 2010 or 2009, as management believes all outstanding accounts receivable are fully collectible.
 
Fair Value of Financial Instruments
 
The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced sale or liquidation. Significant differences can arise between the fair value and carrying amounts of financial instruments that are recognized at historical cost amounts. The Company considers that fair value should be based on the assumptions market participants would use when pricing the asset or liability.
 
The following methods are used to estimate the Company’s financial instruments:
 
 
(a)
Cash equivalents, grants receivables, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these instruments;
 
 
(b)
Available-for-sale securities are recorded based primarily on quoted market prices;
 
 
(c)
Put/call liability’s fair value is based on revenue projections and business, general economic and market conditions that could be reasonably evaluated as of the valuation date;
 
It is not practical for the Company to estimate the fair value of the convertible notes payable due to the specific provisions of these notes. The terms of these notes are disclosed at Note 10. See Note 15 for discussion on fair value measurements.
 
Earnings per Share
 
Net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding. The Company has certain common share equivalents, which are described more fully in Note 8 which have not been used in the calculation of diluted net income (loss) per share because to do so would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for each year are equal.
 
 
Share-based Compensation
 
The Company has various share-based employee and non-employee compensation plans, which are described more fully in Note 7.
 
The Company accounts for stock options and restricted stock granted to employees and non-employees by recognizing the costs resulting from all share-based payment transactions in the consolidated financial statements at their fair values. The Company estimates the fair value of each option on the date of grant using the Black-Scholes closed-form option-pricing model based on assumptions for the expected term of the stock options, expected volatility of its common stock, prevailing interest rates, and an estimated forfeiture rate.
 
Segment Information
 
The Company is managed and operated as one business. 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 product candidates. Accordingly, the Company does not prepare discrete financial information with respect to separate product candidates or by location and does not have separately reportable segments.
 
Comprehensive Income
 
Unrealized gains (losses) from the Company’s investment securities are included in accumulated other comprehensive income (loss) within the consolidated balance sheet.
 
Reclassification
 
Certain prior period amounts have been reclassified to conform to current year presentation.
 
Recent Accounting Pronouncements
 
In April 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2010-17, Revenue Recognition — Milestone Method (ASU 2010-17). ASU 2010-17 provides guidance in applying the milestone method of revenue recognition to research or development arrangements. Under this guidance management may recognize revenue contingent upon the achievement of a milestone in its entirety, in the period in which the milestone is achieved, only if the milestone meets all the criteria within the guidance to be considered substantive. This ASU is effective on a prospective basis for research and development milestones achieved in fiscal years, beginning on or after June 15, 2010. Early adoption is permitted; however, the Company has elected to implement ASU 2010-17 prospectively, and as a result, the effect of this guidance will be limited to future transactions. Adoption of this standard may have a material impact on the Company’s financial position or results of operations with regards to future milestones or arrangements.

In October 2009, the FASB issued ASU No. 2009-13, Revenue Recognition — Multiple-Deliverable Revenue Arrangements (ASU 2010-13). This new standard impacts the determination of when the individual deliverables included in a multiple-element arrangement may be treated as separate units of accounting. Additionally, these new standards modify the manner in which the transaction consideration is allocated across the separately identified deliverables by no longer permitting the residual method of allocating arrangement consideration. These new standards are required to be adopted in the first quarter of 2011. The Company does not expect this new standard to significantly impact its consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-27, Fees Paid to the Federal Government by Pharmaceutical Manufacturers (ASU 2010-27). ASU 2010-27 provides guidance concerning the recognition and classification of the new annual fee payable by branded prescription drug manufactures and importers on branded prescription drugs which was mandated under the health care reform legislation enacted in the U.S. in March 2010. Under this new accounting standard, the annual fee would be presented as a component of operating expenses and recognized over the calendar year such fees are payable using a straight-line method of allocation unless another method better allocates the fee over the calendar year. This ASU is effective for calendar years beginning on or after December 31, 2010, when the fee initially becomes effective. As this standard relates only to classification, the adoption of this accounting standard will not have an impact on the Company’s financial position or results of operations.

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 other than those disclosed in Note 16.

Offerings of Common Stock
 
The Company completed a follow-on public offering in February 2008. As part of that offering, 3,712,000 shares of the Company’s common stock were sold, resulting in proceeds of approximately $74.6 million, net of issuance costs.
 
The Company completed a follow-on public offering in August 2008. As part of that offering, 4,600,000 shares of the Company’s common stock were sold, resulting in proceeds of approximately $126.6 million, net of issuance costs.
 
Short-Term Investments

 (4) Short-Term Investments
 
The Company has determined that all of its short-term 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:

US Treasury bonds
 $224,669,409  $126,170  $(17,556) $224,778,023 
 
The Company’s short-term investments consist of US Treasury bonds with original maturities greater than three months and less than one year. A decline in the market value of any available-for-sale security below cost that is deemed to be other-than-temporary results in a reduction in carrying amount to fair value. The impairment would be charged to earnings for the difference between the investment’s cost and fair value at such date and a new cost basis for the security established. Factors evaluated to determine if an investment is other-than-temporarily impaired include significant deterioration in the earnings performance, credit rating, asset quality, or business prospects of the issuer; adverse changes in the general market condition in which the issuer operates; the intent and ability to retain the investment for a sufficient period of time to allow for recovery in the market value of the investment; and, issues that raise concerns about the issuer’s ability to continue as a going concern. The Company has determined that there were no other-than-temporary declines in the fair values of its short term investments as of December 31, 2010.
 
Short-term investments with maturity of three months or less from date of purchase have been classified as cash and cash equivalents, and amounted to $23,529,109 and $43,471,757 as of December 31, 2010 and 2009, respectively.

Common Stock Options and Restricted Stock
Common Stock Options and Restricted Stock
(7) Common Stock Options and Restricted Stock
 
On June 18, 1999, the Company’s board of directors approved the adoption of the Acorda Therapeutics, Inc. 1999 Employee Stock Option Plan (the 1999 Plan). All employees of the Company were eligible to participate in the 1999 Plan, including executive officers, as well as directors, independent contractors, and agents of the Company. The number of shares authorized for issuance under the 1999 Plan was 2,481,334.
 
On January 12, 2006, the Company’s board of directors approved the adoption of the Acorda Therapeutics, Inc. 2006 Employee Incentive Plan (the 2006 Plan). This 2006 Plan serves as the successor to the Company’s 1999 Plan, as amended, and no further option grants or stock issuances shall be made under the 1999 Plan after the effective date, as determined under Section 14 of the 2006 Plan. All employees of the Company are eligible to participate in the 2006 Plan, including executive officers, as well as directors, independent contractors, and agents of the Company. The 2006 Plan also covers the issuance of restricted stock. The 2006 Plan is administered by the Compensation Committee of the Board of Directors, which selects the individuals to be granted options and stock appreciation rights, determines the time or times at which options and stock appreciation rights shall be granted under the 2006 Plan, determines the number of shares to be granted subject to any option or stock appreciation right under the 2006 Plan and the duration of each option and stock appreciation right, and makes any other determinations necessary, advisable, and/or appropriate to administer the 2006 Plan. Under the 2006 Plan, each option granted expires no later than the tenth anniversary of the date of its grant. The number of shares of common stock reserved for issuance pursuant to awards made under the 2006 Plan as of December 31, 2010 is 6,803,036 shares of stock. The total number of shares of common stock available for issuance under this 2006 Plan, including shares of common stock subject to the then outstanding awards, shall automatically increase on January 1 of each year during the term of this plan, beginning 2007, by a number of shares of common stock equal to 4% of the outstanding shares of common stock on that date, unless otherwise determined by the Board of Directors. The Board approved the automatic increases of 4% for 2010 and 2009 and 3% for 2008. Upon the exercise of options in the future, the Company intends to issue new shares.
 
The fair value of each option granted is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:
 
 
             Twelve-month period ended December 31,
 
                          2010
                         2009
                       2008

5.56
5.30
Risk free interest rate
2.57%
2.15%
2.85%
Dividend yield
 
 
The Company estimated volatility for purposes of computing compensation expense on its employee and non-employee options using a combination of the volatility of the Company’s stock price since October 1, 2006 and the volatility of public companies that the Company considered comparable. The expected life used to estimate the fair value of employee options is 5.50 years. The Company based this assumption on the 50th percentile of 10 peer companies’ choices for expected life for their valuations.
 
The weighted average fair value per share of options granted to employees and directors for the years ended December 31, 2010, 2009 and 2008 amounted to approximately $19.29, $14.33, and $14.20 respectively. 15,000 options were granted to non-employees for the year ended December 31, 2008 and no options were granted to non-employees for the years ended December 31, 2010 and 2009.
 
During the year ended December 31, 2010, the Company granted 1,470,197 stock options and restricted stock awards to employees and directors under the 2006 Plan. These stock options were issued with a weighted average exercise price of $32.49 per share. 600 of these options vested immediately, 70,000 of these options vest over a one-year vesting schedule and 1,065,419 will vest over a four-year vesting schedule. 91,667 of the restricted stock awards granted in 2010 vest over a three-year vesting schedule, 232,511 restricted stock awards vest over a four-year vesting schedule, and 10,000 restricted stock awards vested within three months. As a result of these grants the total compensation charge to be recognized over the service period is $30,049,633, of which $7,208,053 was recognized during the year ended December 31, 2010.
 
Compensation costs for options and restricted stock granted to employees and directors amounted to $17,777,242, $12,277,929, and $9,552,236, for the twelve-month periods ended December 31, 2010, 2009, and 2008, respectively. There were no compensation costs capitalized in inventory balances. Compensation expense for options and restricted stock granted to employees and directors are classified between research and development, sales and marketing and general and administrative expense based on employee job function.

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.
 
For the twelve months ended December 31, 2010 and 2009, options to purchase 4,084,081 shares and 3,711,778 shares, respectively, of common stock that could potentially dilute basic earnings per share in the future were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive.  For the twelve months ended December 31, 2010 and 2009, 323,716 and 203,776 shares, respectively, of unvested restricted stock that could potentially dilute basic earnings per share in the future were excluded from the calculation of diluted earnings per common share as their effect would have been anti-dilutive.

The Company had available federal net operating loss (NOL) carry-forwards of approximately $266.9 million and $249.5 million and state NOL carry-forwards of approximately $261.0 million and $247.4 million as of December 31, 2010 and 2009 respectively which may be available to offset future taxable income, if any. The federal losses are expected to expire between 2019 and 2030 while the state losses are expected to expire between 2012 and 2030. The Company also has research and development tax credit carry-forwards of approximately $3.7 million and $1.6 million as of December 31, 2010 and 2009, for federal income tax reporting purposes that may be available to reduce federal income taxes, if any, and expire in future years beginning in 2019.  The Company is no longer subject to federal or state income tax audits for tax years prior to 2006 however, such taxing authorities can review any net operating losses utilized by the Company in years subsequent to 1999. The Company also has Alternative Minimum Tax credit carry-forwards of $0.2 and $0.3 million as of December 31, 2010 and 2009, respectively.  Such credits can be carried forward indefinitely and have no expiration date.

Changes in the valuation allowance for the years ended December 31, 2010 and 2009 amounted to approximately $6.6 million and $27.7 million, respectively. A tax benefit of $7.8 million associated with the exercise of stock options will be recorded in additional paid-in capital when the associated net operating loss is recognized. Since inception, the Company has incurred substantial losses and may incur substantial losses in future periods. The Tax Reform Act of 1986 (the Act) provides for a limitation of the annual use of NOL and research and development tax credit carry-forwards (following certain ownership changes, as defined by the Act) that could significantly limit the Company’s ability to utilize these carry-forwards. The Company has experienced various ownership changes, as a result of past financings. Accordingly, the Company’s ability to utilize the aforementioned carry-forwards may be limited. Additionally, because U.S. tax laws limit the time during which these carry-forwards may be applied against future taxes, the Company may not be able to take full advantage of these attributes for federal income tax purposes. Because of the above mentioned factors, the Company has not recognized its gross deferred tax assets as of and for all periods presented. As of December 31, 2010, management believes that it is more likely than not that the net deferred tax assets will not be realized based on future operations and reversal of deferred tax liabilities. Accordingly, the Company has provided a full valuation allowance against its gross deferred tax assets and no tax benefit has been recognized relative to its pretax losses.
 
On January 1, 2007, the Company adopted FIN 48, which was later superseded by ASC 740-10, which clarifies the accounting for income taxes by prescribing the minimum threshold a tax position is required to meet before being recognized in the financial statements as well as guidance on de-recognition, measurement, classification and disclosure of tax positions.  There were no uncertain tax positions at December 31, 2010.
 
License and Research and Collaboration Agreements
License and Research and Collaboration Agreements
(10) License and Research and Collaboration Agreements
 
Elan
 
In September 2003, the Company entered into an amended and restated license agreement and a supply agreement with Elan for Ampyra, which replaced two prior license and supply agreements. Under the license agreement, Elan granted the Company exclusive worldwide rights to Ampyra, as well as Elan’s formulation for any other mono or di-aminopyridines, for all indications, including multiple sclerosis and spinal cord injury. The Company agreed to pay Elan milestone payments and royalties based on a percentage of net product sales and the quantity of product shipped by Elan to Acorda.
 
Subject to early termination provisions, the Elan license terminates on a country by country basis on the latter to occur of fifteen years from the date of the agreement, the expiration of the last to expire Elan patent or the existence of competition in that country.
 
Under the supply agreement, Elan has the right to manufacture for the Company, subject to certain exceptions, Ampyra and other products covered by these agreements at specified prices calculated as a percentage of net product sales of the product shipped by Elan to Acorda. In the event Elan does not manufacture the products, it is entitled to a compensating payment for the quantities of product provided by the alternative manufacturer.
 
Convertible Note
 
Under the Agreement, Elan also loaned to the Company an aggregate of $7.5 million pursuant to two convertible promissory notes. On December 23, 2005, Elan transferred these promissory notes to funds affiliated with Saints Capital. One promissory note in the amount of $5.0 million bears interest at a rate of 3% beginning on the first anniversary of the issuance of the note. The unpaid principal is convertible into 67,476 shares of common stock. Principal and interest are repayable, if not converted, ratably over a seven-year period beginning one year after the Company receives certain regulatory approval for the products to be developed, subject to limitations related to gross margin on product sales. The $5.0 million promissory note restricts the Company’s ability to incur indebtedness that is senior to the notes, subject to certain exceptions, including for the Company’s revenue interest assignment arrangement (See Note 14).
 
The second promissory note was in the amount of $2.5 million and was non-interest bearing. In December 2006, Saints Capital exercised the conversion of this note into 210,863 shares of common stock.
 
On January 22, 2010, the Company received regulatory approval for the product under development that was subject to this convertible note payable. Saints Capital held the option to convert the outstanding principal into common stock until the first anniversary of regulatory approval or January 22, 2011. Saints Capital did not convert by the first anniversary date, therefore the Company is obligated to pay the outstanding principal sum on the promissory note, together with all accrued and unpaid interest, subject to limitations related to gross margin on product sales, in seven equal installments, the first of which was paid on the maturity date, and the balance shall be paid on the six successive anniversaries of the maturity date. The Company, at its option, may at any time prepay in whole or in part, without penalty, the principal balance together with accrued interest to the date of payment, by giving Saints Capital written notice at least thirty days prior notice to the date of prepayment.
 
Interest on this convertible promissory note has been imputed using 3% on the $5 million note.
 
Supply Agreement
 
In September 2003, the Company entered into a supply agreement with Elan relating to the manufacture and supply of Ampyra by Elan. The Company agreed to purchase at least 75% of its annual requirements of Ampyra from Elan, unless Elan is unable or unwilling to meet its requirements, for a percentage of net product sales and the quantity of product shipped by Elan to Acorda. In those circumstances, where the Company elects to purchase less than 100% of its requirements from Elan, the Company agreed to make certain compensatory payments to Elan. Elan agreed to assist the Company in qualifying a second manufacturer to manufacture and supply the Company with Ampyra subject to its obligations to Elan.
 
As permitted by the agreement with Elan, the Company has designated Patheon, Inc. (Patheon) as a qualified second manufacturing source of Ampyra. In connection with that designation, Elan assisted the Company in transferring manufacturing technology to Patheon. The Company and Elan have agreed that a purchase of up to 25% of annual requirements from Patheon are allowed if compensatory payments are made to Elan. In addition, Patheon may supply the Company with Ampyra if Elan is unable or unwilling to meet the Company’s requirements.
 
Biogen Idec
 
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 fampridine 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 Elan Pharma International Limited, a subsidiary of Elan Corporation plc (Elan). Biogen Idec has responsibility for regulatory activities and future clinical development of Ampyra 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 Elan.
 
Under the Collaboration Agreement, the Company was entitled to an upfront payment of $110.0 million as of June 30, 2009, which was received on July 1, 2009, and will be entitled to receive additional payments of up to approximately $400 million based on the successful achievement of future regulatory and 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 Elan or other suppliers for ex-U.S. sales, including manufacturing costs and royalties owed. 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 Elan 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 Elan 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. The Supply Agreement is a contingent deliverable at the onset of the agreement.  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 Elan as expense ratably over the estimated term of regulatory exclusivity for the licensed products under the Collaboration Agreement as we had determined this was the most probable expected benefit period. The Company recognized $9.4 million in license revenue, a portion of the $110.0 million received from Biogen Idec and $660,000 in cost of license revenue, a portion of the $7.7 million paid to Elan during the twelve-month period ended December 31, 2010. As of December 31, 2010 the Company estimated the recognition period to be approximately 12 years from the date of the Collaboration Agreement.  See Note 16.

Employee Benefit Plan
Employee Benefit Plan
 (11) Employee Benefit Plan
 
Effective September 1, 1999, the Company adopted a defined contribution 401(k) savings plan (the 401(k) plan) covering all employees of the Company. Participants may elect to defer a percentage of their annual pretax compensation to the 401(k) plan, subject to defined limitations. Effective January 1, 2007, the Company amended the plan to include an employer match contribution to employee deferrals. For each dollar an employee invests up to 6% of his or her earnings, the Company will contribute an additional 50 cents into the funds. The Company’s expense related to the plan was $1.0 million, $757,000 and $548,000 for the years ended December 31, 2010, 2009, and 2008, respectively.
 
Commitments and Contingencies

During 1998, the Company entered into a lease agreement for its corporate office. During November 2000, May 2001, February 2007, July 2008 and February 2009, the Company entered into amendments of the lease for its facility. Under the amendments, the Company increased the total leased space and extended the lease term for its original leased space. The lease is subject to cancellation by us upon 12 months notice with no penalty. Future minimum commitments under all non-cancelable leases required subsequent to December 31, 2010 are as follows:
 
2011
 $1,149,000 
2012
  1,149,000 
   $2,298,000 
 
Rent expense under these operating leases during the years ended December 31, 2010, 2009 and 2008 was $1.1 million, $1.0 million, and $882,000, respectively.
 
Under the Company’s Ampyra license agreement with Elan, the Company is obligated to make milestone payments to Elan of up to $15.0 million over the life of the contract and royalty payments as a percentage of net product sales and the quantity of product shipped by Elan to Acorda. In addition, under the Company’s various other research, license and collaboration agreements with other parties, it is obligated to make milestone payments of up to an aggregate of approximately $16.8 million over the life of the contracts. The FDA approval of Ampyra triggered a milestone of $2.5 million to Elan that was paid during the quarter ended June 30, 2010. Further milestone amounts are payable in connection with additional indications.
 
Under the Company’s Ampyra supply agreement with Elan, payments for product manufactured by Elan are calculated as a percentage of net product sales and the quantity of product shipped by Elan to Acorda. Under this agreement, Acorda also has the option to purchase an agreed to quantity of product from a second source provided Acorda makes a compensating payment to Elan for the quantities of product provided by the second source.
 
Under the Company’s license agreement with Rush-Presbyterian-St. Luke’s Medical Center, it is obligated to make royalty payments as a percentage of net sales in the United States and in countries other than the United States.
 
Under the Company’s license agreement with Cornell Research Foundation, Inc., it is also obligated to pay Cornell an annual royalty on certain sales of Ampyra, subject to a minimum annual royalty requirement of $25,000.
 
Under the Company’s supply agreement with Elan, it provides Elan with monthly written 18-month forecasts, and with annual written five-year forecasts for its supply requirements of Ampyra and two-year forecasts for its supply requirements of Zanaflex Capsules. In each of the five months for Zanaflex and three months for Ampyra following the submission of our written 18-month forecast the Company is obligated to purchase the quantity specified in the forecast, even if its actual requirements are greater or less.
 
Under the terms of the employment agreement with the Company’s chief executive officer, the Company is obligated to pay severance under certain circumstances. If the employment agreement is terminated by the Company or by the Company’s chief executive officer for reasons other than for cause, the Company must pay (i) an amount equal to the base salary the chief executive officer would have received during the fifteen month period immediately following the date of termination, plus (ii) bonus equal to last annual bonus received by the chief executive officer multiplied by a fraction, the numerator of which shall be the number of days in the calendar year elapsed as of the termination date and the denominator of which shall be 365.
 
The Company is also party to employment agreements with its other executive officers, who are the Company’s chief scientific officer, executive vice president and general counsel and chief financial officer, that govern the terms and conditions of their employment. If any of the employment agreements are terminated by the Company or by the executives for reasons other than for cause, the Company must pay an amount equal to (i) the base salary the executive would have received during the nine month period immediately following the date of termination in the case of the chief scientific officer and a seven month period immediately following the date of termination in the case of the executive vice president and general counsel and chief financial officer, plus (ii) a bonus equal to the last annual bonus received by the executive multiplied by a fraction, the numerator of which shall be the number of days in the calendar year elapsed as of the termination date and the denominator of which shall be 365.
 
In August 2007, the Company received a Paragraph IV Certification Notice from Apotex Inc. advising that it had submitted an Abbreviated New Drug Application (ANDA) to the FDA seeking marketing approval for generic versions of Zanaflex Capsules. In October 2007, the Company filed a lawsuit against Apotex Corp. and Apotex Inc. (collectively, Apotex) for patent infringement in relation to the filing of the ANDA by Apotex. The defendants have answered the Company’s complaint, asserting patent invalidity and non-infringement and counterclaiming, seeking a declaratory judgment of patent invalidity and non-infringement. The Company has denied those counterclaims. In March 2008, Apotex filed a motion, which the Company opposed, for partial judgment on the pleadings dismissing the Company’s request for relief on the ground that the case is “exceptional” under U.S.C. §§ 271(e)(4) or 285. The court ruled in the Company’s favor and denied Apotex’ motion in December 2008.  Fact discovery in the case has been completed. On July 2, 2010, the court held a Markman hearing to determine the interpretation of certain terms in the Company’s Zanaflex Capsules patent that is at issue in this litigation. The court ruled favorably on a number of those terms, and the case is proceeding.  A trial date of April 25, 2011 has been set by the court.  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. As of December 31, 2010 there have been no accruals for legal matters aside from payments related to the litigation itself.
 
Intangible Assets
Intangible Assets
(13) Intangible Assets
 
The Company acquired all of Elan’s U.S. sales, marketing and distribution rights to Zanaflex Capsules and Zanaflex tablets in July 2004 for $2.0 million plus $675,000 for finished goods inventory. The Company was also responsible for up to $19.5 million in future contingent milestone payments based on cumulative gross sales of Zanaflex tablets and Zanaflex Capsules. As of December 31, 2009, the Company made $19.5 million of these milestone payments which were recorded as intangible assets in the consolidated financial statements.
 
In connection with this transaction, the Company acquired the rights to the trade name “Zanaflex®”, one issued U.S. patent and two patent applications related to Zanaflex Capsules, and the remaining tablet inventory on hand with Elan. Additionally, the Company assumed Elan’s existing contract with Novartis to manufacture Zanaflex tablets and entered into a separate contract with Elan to manufacture Zanaflex Capsules. The Company separately launched Zanaflex Capsules in April 2005. The Company did not acquire any receivables, employees, facilities or fixed assets. The Company allocated, on a relative fair value basis, the initial and milestone payments made to Elan to the assets acquired, principally the Zanaflex trade name and the capsulation patent. There is no expected residual value of these intangible assets. The Company amortizes the allocated fair value of the trade name and patent over their estimated future economic benefit to be achieved.  The Zanaflex trade name was fully amortized as of December 31, 2008.
 
On January 22, 2010, the Company received marketing approval from the FDA for Ampyra triggering two milestone payments of $2.5 million to Elan and $750,000 to Rush-Presbyterian St. Luke’s Medical Center (Rush).  As of December 31, 2010, the Company made these milestone payments totaling $3.25 million and they were recorded as intangible assets in the consolidated financial statements.

In 1990, Elan licensed from Rush know-how relating to dalfampridine (4-aminopyridine, 4-AP, the formulation used in Ampyra), for the treatment of MS. The Company subsequently licensed this know-how from Elan. In September 2003, the Company entered into an agreement with Rush and Elan terminating the Rush license to Elan and providing for mutual releases. The Company also entered into a license agreement with Rush in 2003 in which Rush granted the Company an exclusive worldwide license to its know-how relating to dalfampridine for the treatment of MS. Rush has also assigned to the Company its Orphan Drug Designation for dalfampridine for the relief of symptoms of MS.

The Company agreed to pay Rush a license fee, milestone payments of up to $850,000 and royalties based on net sales of the product for neurological indications. As of December 31, 2009, the Company had made an aggregate of $100,000 in payments under this agreement.  The FDA approval of Ampyra triggered the final milestone of $750,000 which was paid during the three-months ended March 31, 2010.  As of December 31, 2010, the Company made or accrued royalty payments totaling $2.7 million.

In August 2003, the Company entered into an Amended and Restated License Agreement with the Canadian Spinal Research Organization (CSRO). Under this agreement, the Company was granted an exclusive and worldwide license under certain patent assets and know-how of CSRO relating to the use of dalfampridine in the reduction of chronic pain and spasticity in a spinal cord injured subject.  The agreement required the Company to pay to CSRO royalties based on a percentage of net sales of any product incorporating the licensed rights, including royalties on the sale of Ampyra and on the sale of dalfampridine for any other indication. During the three-month period ended March 31, 2010, the Company purchased CSRO’s rights to all royalty payments under the agreement with CSRO for $3.0 million.  This payment was recorded as an intangible asset in the consolidated financial statements.
 
Intangible assets also include certain website development costs which have been capitalized. The Company has developed several websites, each with its own purpose, including the general corporate website, product information websites and websites focused on the MS community.
 
The Company continually evaluates whether events or circumstances have occurred that indicate that the estimated remaining useful life of its intangible assets may warrant revision or that the carrying value of these assets may be impaired. As of December 31, 2010, the Company does not believe that there are any facts or circumstances that would indicate a need for changing the estimated remaining useful life of our intangible assets.

Convertible Note
 
In September 2003, the Company entered into an amended and restated license agreement and a supply agreement with Elan, which replaced two prior license and supply agreements for Ampyra.  Under the license agreement, Elan also loaned to the Company an aggregate of $7.5 million pursuant to two convertible promissory notes. On December 23, 2005, Elan transferred these promissory notes to funds affiliated with Saints Capital. One promissory note remains outstanding in the amount of $5.0 million bears interest at a rate of 3% beginning on the first anniversary of the issuance of the note (See Note 10).
 
Sale of Revenue Interest
 
On December 23, 2005, the Company entered into an agreement with an affiliate of Paul Royalty Fund (PRF), under which the Company received $15 million in cash. In exchange the Company has assigned PRF revenue interest in Zanaflex Capsules, Zanaflex tablets and any future Zanaflex products. The agreement covers all Zanaflex net revenues (as defined in the agreement) generated from October 1, 2005 through and including December 31, 2015, unless the agreement terminates earlier. In November 2006, the Company entered into an amendment to the revenue interest assignment agreement with PRF. Under the terms of the amendment, PRF paid the Company $5.0 million in November 2006. An additional $5.0 million was due if the Company’s net revenues during the fiscal year 2006 equaled or exceeded $25.0 million. This milestone was met and the receivable was reflected in the Company’s December 31, 2006 financial statements. Under the terms of the amendment, the Company is paid 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 to the agreement, 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 amended agreement that are at least 2.1 times the aggregate amount PRF has paid the Company under the agreement, PRF will only be entitled to 1% of Zanaflex net revenues. If PRF is entitled to 15% of net revenues as described above, the Company will remit 8% of cash payments received from wholesalers to PRF on a daily basis, with a quarterly reconciliation and settlement.
 
In connection with the transaction, the Company recorded a liability, referred to as the revenue interest liability. The Company imputes interest expense associated with this liability using the effective interest rate method and records 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. The Company currently estimates 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. The Company recorded approximately $3.8 million, $4.2 million and $5.4 million in interest expense related to this agreement in 2010, 2009 and 2008, respectively. Interest expense in 2008 included a $1.4 million out-of-period adjustment made during the second quarter of 2008 to correct an error identified in the previously recorded effective interest expense related to the November 2006 amended revenue interests assignment agreement with PRF. This out-of-period adjustment did not increase the total interest expense associated with this agreement. Through December 31, 2010, $38.0 million in payments have been made to PRF as a result of Zanaflex sales levels and milestones reached.
 
The agreement also contains put and call options whereby the Company may repurchase the revenue interest at its option or can be required by PRF to repurchase the revenue interest, contingent upon certain events. If the Company experiences a change of control, undergoes certain bankruptcy events, transfers any of their interests in Zanaflex (other than pursuant to a license agreement, development, commercialization, co-promotion, collaboration, partnering or similar agreement), transfers all or substantially all of its assets, or breaches certain of the covenants, representations or warranties made under the agreement, PRF has the right, which the Company refers to as PRF’s put option, to require the Company to repurchase the rights sold to PRF at the “put/call price” in effect on the date such right is exercised. If the Company experiences a change of control it has the right, which the Company refers to as the Company’s call option, to repurchase the rights sold to PRF at the “put/call price” in effect on the date such right is exercised. If the Company’s call option becomes exercisable as a result of this trigger, the Company will have a period of 180 days during which to exercise the option. The Company does not currently intend to exercise its call option if it becomes exercisable as a result of such a transaction but may reevaluate whether it would exercise the option during the 180-day period. The put/call price on a given date is the greater of (i) 150% of all payments made by PRF as of such date, less all payments received by PRF 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 as of such date, taking into account the amount and timing of all payments received by PRF as of such date. The Company has determined that PRF’s put option and the Company’s call option meet the criteria to be considered an embedded derivative and should be accounted for as such. The Company recorded a net liability of $391,000 as of December 31, 2010 related to the put/call option to reflect its current estimated fair value. This liability is revalued on a semi-annual basis to reflect any changes in the fair value and any gain or loss resulting from the revaluation is recorded in earnings. For the year ended December 31, 2010, a gain of $246,500 has been recorded as a result of the change in the fair value of the net put/call liability balance from December 31, 2009.
 
Fair Value Measurements
Fair Value Measurements
(15) Fair Value Measurements
 
The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts. The Company bases fair value on the assumptions market participants would use when pricing the asset or liability.
 
The Company utilizes a fair value hierarchy which requires it to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company primarily applies the market approach for recurring fair value measurements. The standard describes three levels of inputs that may be used to measure fair value:
 
 
Level 1 Quoted prices in active markets for identical assets or liabilities.
 
 
Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
 
 
Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
 
The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2010, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.

 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 fampridine to improve walking ability in adult patients with multiple sclerosis.  Biogen Idec has appealed this opinion and requested a re-examination of the decision by the CHMP.  The Company is currently evaluating the impact on the period for the amortization of the deferred collaboration revenue and cost of license revenue, but it is likely to increase the amortization period and therefore decrease the amount of revenue recognized per period in the future.
