Nature of the Business | 1. Nature of the Business Achillion Pharmaceuticals, Inc. (the “Company”) was incorporated on August 17, 1998 in Delaware. The Company is seeking to transform innovation into novel treatments that address the needs of patients by discovering and developing small molecule therapeutics for the treatment of infectious diseases and immune system disorders. The Company is devoting substantially all of its efforts towards product research and development. The Company incurred losses of $458,802 from inception through September 30, 2015 and had an accumulated deficit of $472,664 at September 30, 2015, which includes preferred stock dividends recognized until the Company’s initial public offering in 2006. The Company has funded its operations primarily through the sale of equity securities. Based on the Company’s current clinical plan, the Company believes that its existing cash, cash equivalents and marketable securities will be sufficient to meet its current projected operating requirements for at least the next 12 months. However, the Company’s future capital requirements may change and will depend upon numerous factors, including but not limited to:

Accounting Standards Updates | 2. Accounting Standards Updates In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes all existing revenue recognition requirements, including most industry-specific guidance. ASU No. 2014-09 requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” which delays the effective date of ASU No. 2014-09 by one year. The new standard is effective for reporting periods beginning after December 15, 2017. The Company does not believe ASU No. 2014-09 will have a material effect on its financial position and results of operations. In August 2014, FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern.” ASU No. 2014-15 provides guidance regarding management’s responsibility to evaluate whether there exists substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. ASU No. 2014-15 is effective for annual reporting periods beginning after December 15, 2016, and interim periods thereafter. The Company does not believe ASU No. 2014-15 will have a material effect on its financial position and results of operations. In April 2015, FASB issued ASU No. 2015-03, “Interest – Imputation of Interest.” ASU No. 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015 (and interim periods within those fiscal years) with early adoption permitted and retrospective application required. The Company does not believe ASU No. 2015-03 will have a material effect on its financial position and results of operations. |

Earnings (Loss) Per Share | 5. Earnings (Loss) Per Share Basic earnings (loss) per share (“EPS”) is calculated in accordance with Accounting Standards Codification (“ASC”) 260, Earnings Per Share, by dividing net income or loss attributable to common stockholders by the weighted average common stock outstanding. Diluted EPS is calculated by adjusting weighted average common shares outstanding for the dilutive effect of common stock options and warrants. In periods in which a net loss is recorded, no effect is given to potentially dilutive securities, since the effect would be antidilutive. Securities that could potentially dilute basic EPS in the future are not included in the computation of diluted EPS during periods where there is a net loss because to do so would be antidilutive. The calculations of basic and diluted net loss per share are as follows:
Potentially dilutive securities outstanding as of September 30, 2015 and 2014 are as follows:
For the three months ended September 30, 2015, differences between basic and diluted weighted average common shares outstanding resulted from the dilutive effect of warrants outstanding and awards granted under the Company’s stock incentive plan. Excluded from the computation of diluted net income per share are stock options to purchase 3,816 shares of common stock that were outstanding during the three months ended September 30, 2015. These options were outstanding but were excluded because they were antidilutive, as the option exercise price was greater than the average market price of the Company’s common stock. |

Collaboration Arrangement | 6. Collaboration Arrangement In May 2015, the Company entered into parallel transactions with Janssen and its affiliate, Johnson & Johnson Innovation-JJDC, Inc. (“JJDC”), consisting of (i) an exclusive collaboration and license agreement with Janssen (the “Janssen Agreement”) pursuant to which, upon the closing of the transactions contemplated by the Janssen Agreement on June 29, 2015, the Company granted Janssen exclusive worldwide rights to develop and commercialize products that contain one or more of the Company’s drug candidates for the treatment of chronic hepatitis C virus (“HCV”) infection, namely odalasvir, also known as ACH-3102, a second-generation NS5A inhibitor, ACH-3422, an NS5B HCV polymerase inhibitor, and sovaprevir, an NS3/4A HCV protease inhibitor, and (ii) a stock purchase agreement with JJDC (the “Stock Purchase Agreement”) pursuant to which, upon the closing of the transactions contemplated by the Stock Purchase Agreement, JJDC purchased 18,367 shares of the Company’s common stock (the “Shares”) at a price of $12.25 per share, for an aggregate purchase price of $225,000. The Janssen Agreement became effective on June 29, 2015 upon the early termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). The Stock Purchase Agreement became effective July 1, 2015. In connection with the closing of the transactions contemplated by the Stock Purchase Agreement, the Company and JJDC entered into an Investor Agreement (the “Investor Agreement”) on July 1, 2015. Under the terms of the Janssen Agreement, the Company is eligible to receive up to an aggregate of $905,000 in milestone-based payments if licensed products achieve specified development, regulatory and sales milestones. The Company is also eligible to receive royalties on worldwide annual net sales of licensed products, if any, at tiered royalty rate percentages beginning in the mid-teens and rising to the low-twenties, subject to customary reductions. The royalty term is determined on a licensed-product-by-licensed-product and country-by-country basis and begins on the first commercial sale of a licensed product in a country and ends on the expiration of the last to expire of specified patents or regulatory exclusivity covering such licensed product in such country or, with a customary royalty reduction, ten years after such first commercial sale if there is no such exclusivity. Janssen will bear the future costs of worldwide development and commercialization of licensed products, subject to specified exceptions relating to the Company’s ongoing studies and technology transfer. The term of the Janssen Agreement will continue, unless earlier terminated, until expiration of the royalty term for licensed products or all payment obligations under the Janssen Agreement. Janssen may terminate the Janssen Agreement upon 60 days’ written notice to the Company at any time prior to submission of the first application for marketing approval for a licensed product in any of the specified major market countries. Janssen may also terminate the Janssen Agreement under specified circumstances relating to the safety or regulatory approvability of a licensed product. Either the Company or Janssen may terminate the Janssen Agreement if the other party is in material breach of the agreement and fails to cure such breach within specified cure periods. Either the Company or Janssen may terminate the Janssen Agreement in the event of specified insolvency events involving the other party. Upon any early termination, rights to the Company’s licensed drug candidates will revert to the Company. Pursuant to the terms of the Janssen Agreement, the Company is required to provide technology transfer services related to the chemistry, manufacturing and know-how to Janssen for up to 180 days after the effective date. In accordance with ASC 605-25, which provides guidance on accounting for multiple-element arrangements, including the determination of the units of accounting and allocation of total arrangement consideration, the Company identified all of the obligations at the inception of the Janssen Agreement. The significant obligations were determined to be the license and the technology transfer services. The Company has determined that license and technology transfer services represent a single unit of accounting because they were not viewed to have standalone value. The Janssen Agreement entered into by the Company and Janssen, the Stock Purchase Agreement, and the Investor Agreement were entered into by the Company and Janssen’s affiliate in contemplation of each other. The only upfront amount received by the Company in exchange for the license and technology transfer services and the issuance of the Shares was the $225,000. The Company determined that the amount received in excess of the fair value of the Shares upon issuance of $66,122 was attributed to the license and technology services. The Company also determined that there was no discernable pattern in which the technology services would be provided during the 180 day period after the effective date. In accordance with ASC 605-10, the Company determined that straight-line attribution of the license and technology services revenues would be used to recognize revenue. As such, revenue of $34,531 was recorded during the nine months ending September 30, 2015 associated with this transaction. The development, regulatory and sales milestones represent non-refundable amounts that would be paid by Janssen to the Company if certain milestones are achieved in the future. The Company has elected to apply the guidance in ASC 605-28 to the milestones. These milestones, if achieved, are substantive as they relate solely to past performance and are commensurate with estimated enhancement of value associated with the achievement of each milestone as a result of the Company’s performance; however, there can be no assurance that Janssen will achieve the milestones or that the Company will receive the related revenue. Pursuant to the terms of the Investor Agreement, the Shares are subject to a lock-up restriction, such that JJDC agreed it will not, and will also cause its affiliates not to, without the prior approval of the Company, sell, transfer or otherwise dispose of the Shares until the earliest to occur of (i) a specified period after July 1, 2015, (ii) the expiration or earlier termination of the Janssen Agreement or (iii) other specified events. In addition, for the seven year period following the expiration of the lock-up period, subject to specified conditions, the Company has agreed to file a registration statement in order to register all or a portion of the Shares. The Company will not be required to effect more than two such demand registrations for JJDC in the aggregate and is not required to effect more than one such demand registration in any 12 month period. The Company has also agreed to provide JJDC with certain “piggyback” registration rights such that for the seven year period following the expiration of the lock-up period, subject to specified conditions, whenever the Company proposes to register shares of its common stock for its account, JJDC will have the right to include some or all of its Shares in such registration. The Investor Agreement also contains other customary terms and conditions of the parties with respect to the registration of the Shares. Pursuant to the terms of the Investor Agreement, the Shares are subject to a voting agreement, such that until the earliest to occur of (i) a specified period after July 1, 2015, (ii) the expiration or earlier termination of the Janssen Agreement or (iii) other specified events, and subject to specified conditions and excluding specified extraordinary matters, JJDC will, and will cause its permitted transferees to, vote in accordance with the recommendation of the Company’s Board of Directors, or in the case of a meetings of stockholders, if JJDC or a permitted transferee has delivered written notice to the Company at any time prior to the vote on any given matter (but in any event not less than five business days prior to such vote), setting forth its intent to vote on such matter, vote in the same proportion as the votes cast by all other holders of all classes of voting securities of the Company, and JJDC has granted the Company an irrevocable proxy with respect to the foregoing. In addition, pursuant to the terms of the Investor Agreement, the Shares are subject to a standstill agreement, such that until the earliest to occur of (i) a specified period after July 1, 2015 or (ii) other specified events, neither JJDC nor any of its affiliates, except as expressly approved in writing by the Company, will, subject to specified conditions, directly or indirectly, acquire shares of the Company’s outstanding common stock, seek to have called any meeting of the stockholders of the Company, solicit proxies or consents in opposition to the recommendation of a majority of the Company’s Board of Directors with respect to any matter or undertake other specified actions related to the potential acquisition of additional equity interests in the Company. |

Marketable Securities | 7. Marketable Securities The Company applies the provisions of ASC 820, Fair Value Measurements and Disclosures, for financial assets and liabilities measured on a recurring basis which requires disclosure that establishes a framework for measuring fair value and expands disclosures in the financial statements. The guidance requires that fair value measurements be classified and disclosed in one of the three categories: Level 1: Quoted prices in active markets for identical assets and liabilities that the reporting entity has the ability to access at the measurement date; Level 2: Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; or Level 3: Unobservable inputs. The fair value of the Company’s marketable securities of $324,459 and $79,215 as of September 30, 2015 and December 31, 2014, respectively, is valued based on level 2 inputs. The Company’s investments consist mainly of U.S. government and agency securities, government-sponsored bond obligations and certain other corporate debt securities. Fair value is determined by taking into consideration valuations obtained from third-party pricing services. The third-party pricing services utilize industry standard valuation models, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; and other observable inputs. The Company has assessed these as level 2 within the fair value hierarchy of ASC 820. The Company classifies its entire investment portfolio as available for sale as defined in ASC 320, Debt and Equity Securities. Securities are carried at fair value with the unrealized gains (losses) reported as a separate component of stockholders’ equity within accumulated other comprehensive income. The unrealized gain (loss) from marketable securities was $10 and $(12) at September 30, 2015 and December 31, 2014, respectively. As of September 30, 2015 and December 31, 2014, none of the Company’s investments were determined to be other than temporarily impaired. The following table summarizes the Company’s investments:

Debt | 9. Debt Debt consists of the following:
In March 2011, the Company entered into a Master Security Agreement for a $2,000 Capital Expenditure Line of Credit, (the “2011 Credit Facility”) with Webster Bank (“Webster”). Under the 2011 Credit Facility, the Company could draw down equipment loan advances for the purchase of new laboratory equipment through March 2013. In connection with the Master Security Agreement, the Company granted Webster a security interest in equipment to be purchased under the 2011 Credit Facility. In October 2014, the Company entered into a Master Security Agreement for a $1,000 Capital Expenditure Line of Credit (the “2014 Credit Facility”) with Webster. Under the 2014 Credit Facility, the Company can draw down equipment loan advances for the purchase of new laboratory equipment through October 2015. In connection with the Master Security Agreement, the Company granted Webster a security interest in equipment to be purchased under the 2014 Credit Facility. In October 2014 and March 2015, Webster advanced $440 and $229, respectively, to the Company under the 2014 Credit Facility. The fair value for this debt is classified as a level 2 measurement. Fair value is computed using a discounted cash flow model based on current interest rates. At this time, the carrying value approximates fair value. |

Stock-Based Compensation | 10. Stock-Based Compensation On June 2, 2015, the Company’s stockholders approved the Company’s 2015 Stock Incentive Plan, (the “2015 Plan”). The 2015 Plan replaced the Company’s 2006 Stock Incentive Plan, as amended, (the “2006 Plan”). Upon the approval of the 2015 Plan by stockholders, the 2006 Plan terminated, and all then outstanding awards under the 2006 Plan remained in effect, but no additional awards will be made under the 2006 Plan. However, the terms of the 2006 Plan will continue to apply to awards previously granted under the 2006 Plan. The 2015 Plan is administered by the Company’s Board of Directors and allows for the issuance of incentive stock options intended to qualify under Section 422 of the Code, nonstatutory stock options, stock appreciation rights, restricted stock awards and other stock-based awards. The Company’s officers, employees, consultants, advisors and directors are eligible to receive awards under the 2015 Plan; however, incentive stock options may only be granted to employees. Stock options granted are exercisable for a period determined by the Company but in no event longer than ten years from the date of the grant. Stock options generally vest ratably over four years. There were 8,881 shares available to be granted under the 2015 Plan as of September 30, 2015. A summary of the status of the Company’s stock option activity for the nine months ended September 30, 2015 is presented in the table and narrative below:
The Company utilizes the Black-Scholes option pricing model for determining the estimated fair value for stock-based awards. The Black-Scholes option pricing model requires the use of assumptions which determine the fair value of the stock-based awards. The assumptions used to value stock options granted are as follows:
Total compensation expense recorded in the accompanying statements of operations associated with option grants made to employees was $2,129 and $1,536 for the three months ended September 30, 2015 and 2014, respectively and $7,339 and $4,696 for the nine months ended September 30, 2015 and 2014, respectively. The Company recorded no tax benefit related to these stock options since the Company currently maintains a full valuation allowance on its deferred tax assets. As of September 30, 2015, the intrinsic value of the stock options outstanding was $14,578, of which $10,245 related to vested stock options and $4,333 related to unvested stock options. The intrinsic value of stock options is calculated based on the difference between the exercise prices of the underlying common stock and the quoted stock price of the Company’s common stock as of September 30, 2015. As of September 30, 2015, the total compensation cost related to unvested stock options not yet recognized in the financial statements is approximately $16,591, net of estimated forfeitures, and the weighted average period over which this amount is expected to be recognized is 1.4 years. |
