NATURE OF BUSINESS
NATURE OF BUSINESS | 12 Months Ended |
Dec. 31, 2015 | |
NATURE OF BUSINESS | 1. NATURE OF BUSINESS We commenced operations on June 14, 2002 as a biopharmaceutical company seeking to develop and commercialize novel therapeutics based on RNA interference, or RNAi. We are focused on discovering, developing and commercializing RNAi therapeutics by establishing strategic alliances with leading pharmaceutical and life sciences companies, establishing and maintaining a strong intellectual property position in the RNAi field, generating revenues through licensing agreements, and ultimately developing and commercializing RNAi therapeutics for our own account. We have devoted substantially all of our efforts to business planning, research and development, acquiring, filing and expanding intellectual property rights, recruiting management and technical staff, and raising capital. |
SUMMARY OF SIGNIFICANT ACCOUNTI
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 12 Months Ended |
Dec. 31, 2015 | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements reflect the operations of Alnylam and our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the reported amounts 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 reporting period. Actual results could differ from those estimates. Concentrations of Credit Risk and Significant Customers Financial instruments that potentially expose us to concentrations of credit risk consist primarily of cash, cash equivalents and fixed income marketable securities. At December 31, 2015 and 2014, substantially all of our cash, cash equivalents and fixed income marketable securities were invested in money market funds, certificates of deposit, commercial paper, corporate notes, municipal debt securities, U.S. government-sponsored enterprise securities and U.S. treasury securities through highly rated financial institutions. Corporate notes also include foreign bonds denominated in U.S. dollars. Investments are restricted, in accordance with our investment policy, to a concentration limit per issuer. In recent periods, our revenues from collaborations have been generated primarily from Sanofi Genzyme, the specialty care global business unit of Sanofi, or Sanofi Genzyme, Takeda Pharmaceutical Company Limited, or Takeda, Monsanto Company, or Monsanto, The Medicines Company, or MDCO, and Cubist Pharmaceuticals, Inc., or Cubist (now a wholly-owned subsidiary of Merck & Co., Inc.). For the year ended December 31, 2015, our billed and unbilled collaboration receivables were composed primarily of amounts of expense reimbursement due from Sanofi Genzyme and certain milestones due from Ionis Pharmaceuticals, Inc., or Ionis (formerly Isis Pharmaceuticals, Inc.). For the year ended December 31, 2014, our billed and unbilled collaboration receivables were composed primarily of amounts due from Sanofi Genzyme and MDCO based upon the achievement of certain milestones and also, with respect to MDCO, expense reimbursement. The following table summarizes customers that represent greater than 10% of our net revenues from collaborators, for the periods indicated: Year Ended December 31, 2015 2014 2013 Sanofi Genzyme 27 % * * MDCO 25 % 21 % * Takeda 22 % 43 % 47 % Monsanto 14 % 30 % 12 % Cubist * * 21 % The following table summarizes customers with amounts due that represent greater than 10% of our billed and unbilled collaboration receivables balance, at the periods indicated: At December 31, 2015 2014 Sanofi Genzyme 88 % 63 % Ionis 12 % * MDCO * 37 % * Represents 10% or less Fair Value Measurements The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices (adjusted), interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The fair value hierarchy level is determined by the lowest level of significant input. Investments in Marketable Securities We invest our excess cash balances in short-term and long-term marketable debt and equity securities. We classify our investments in marketable debt securities as either held-to-maturity or available-for-sale based on facts and circumstances present at the time we purchased the securities. At each balance sheet date presented, we classified all of our investments in debt and equity securities as available-for-sale. We report available-for-sale investments at fair value at each balance sheet date and include any unrealized holding gains and losses (the adjustment to fair value) in accumulated other comprehensive income (loss), a component of stockholders’ equity. At December 31, 2015, the balance in our accumulated other comprehensive income was composed solely of activity related to our available-for-sale marketable securities, including our investment in equity securities of Regulus Therapeutics Inc., or Regulus. Realized gains and losses are determined using the specific identification method and are included in other income (expense). We did not recognize any realized gains or losses from sales of our available-for-sale securities during the year ended December 31, 2015 and, as a result, did not reclassify any amount out of accumulated other comprehensive income (loss) for the same period. If any adjustment to fair value reflects a decline in the value of the investment, we consider all available evidence to evaluate the extent to which the decline is “other than temporary,” including our intention to sell and, if so, mark the investment to market through a charge to our consolidated statements of comprehensive income (loss). We did not record any impairment charges related to our fixed income marketable securities during the years ended December 31, 2015, 2014 or 2013. Our marketable securities are classified as cash equivalents if the original maturity, from the date of purchase, is 90 days or less, and as marketable securities if the original maturity, from the date of purchase, is in excess of 90 days. Our cash equivalents are composed of commercial paper, corporate notes, U.S. government-sponsored enterprise securities and money market funds. We account for our investment in Regulus as an available-for-sale marketable security. Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income. In periods in which we have a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as other comprehensive income, we must allocate the tax provision to the other categories of earnings. We then record a related tax benefit in continuing operations. Upon sales of our available-for-sale marketable securities, we apply the aggregate portfolio approach to recognize the related tax provision or benefit into income (loss) from continuing operations. As a result, the disproportionate tax effect remains in accumulated other comprehensive income (loss) as long as we maintain an investment portfolio. Estimated Liability for Development Costs We record accrued liabilities related to expenses for which service providers have not yet billed us with respect to products we have received or services that we have incurred, specifically related to ongoing pre-clinical studies and clinical trials. These costs primarily relate to third-party clinical management costs, laboratory and analysis costs, toxicology studies and investigator fees. We have multiple product candidates in concurrent pre-clinical studies and clinical trials at multiple clinical sites throughout the world. In order to ensure that we have adequately provided for ongoing pre-clinical and clinical development costs during the period in which we incur such costs, we maintain an accrual to cover these expenses. We update the estimate for this accrual on at least a quarterly basis. The assessment of these costs is a subjective process that requires judgment. Upon settlement, these costs may differ materially from the amounts accrued in our consolidated financial statements. Our historical accrual estimates have not been materially different from our actual costs. Revenue Recognition We have entered into collaboration agreements with leading pharmaceutical and life sciences companies, including Novartis Pharma AG and one of its affiliates (which assigned its rights and obligations to Arrowhead Research Corporation, or Arrowhead, in early 2015), F. Hoffmann-La Roche Ltd (which assigned its rights and obligations to Arrowhead in 2011), Takeda, Kyowa Hakko Kirin Co., Ltd., or Kyowa Hakko Kirin, Cubist, Monsanto, Sanofi Genzyme and MDCO. The terms of our collaboration agreements typically include deliverables such as non-refundable license fees, funding of research and development, payments based upon achievement of clinical and pre-clinical development milestones, regulatory milestones, manufacturing services, sales milestones and royalties on product sales. These agreements are generally referred to as multiple element arrangements. We apply the accounting standard on revenue recognition for multiple element arrangements. The fair value of deliverables under the arrangement may be derived using a “best estimate of selling price” if vendor specific objective evidence and third-party evidence is not available. Deliverables under the arrangement will be separate units of accounting provided that (i) a delivered item has value to the customer on a standalone basis and (ii) if the arrangement includes a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the control of the vendor. We recognize upfront license payments as revenue upon delivery of the license only if the license has standalone value of the undelivered performance obligations, typically including research and/or steering committee services, can be determined. If the fair value of the undelivered performance obligations can be determined, such obligations would then be accounted for separately as performed. If the license is considered to not have standalone value, the arrangement would then be accounted for as a single unit of accounting and the license payments and payments for performance obligations are recognized as revenue over the estimated period of when the performance obligations are performed or deferred indefinitely until the undelivered performance obligation can be determined. As a biotechnology entity with unique and specialized delivered and undelivered performance obligations, we have been unable to demonstrate standalone value in our multiple element arrangements. Whenever we determine that an arrangement should be accounted for as a single unit of accounting, we determine the period over which the performance obligations will be performed and revenue will be recognized. Revenue is recognized using either a proportional performance or straight-line method. We recognize revenue using the proportional performance method when the level of effort required to complete our performance obligations under an arrangement can be reasonably estimated and such performance obligations are provided on a best-efforts basis. Direct labor hours or full-time equivalents are typically used as the measure of performance. The amount of revenue recognized under the proportional performance method is determined by multiplying the total payments under the contract, excluding royalties and payments contingent upon achievement of milestones, by the ratio of level of effort incurred to date to estimated total level of effort required to complete our performance obligations under the arrangement. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the proportional performance method, as of the period ending date. If we cannot reasonably estimate the level of effort to complete our performance obligations under an arrangement, we recognize revenue under the arrangement on a straight-line basis over the period we are expected to complete our performance obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the straight-line method, as of the period ending date. Significant management judgment is required in determining the level of effort required under an arrangement and the period over which we are expected to complete our performance obligations under an arrangement. Steering committee services that are not inconsequential or perfunctory and that are determined to be performance obligations are combined with other research services or performance obligations required under an arrangement, if any, in determining the level of effort required in an arrangement and the period over which we expect to complete our aggregate performance obligations. Many of our collaboration agreements entitle us to additional payments upon the achievement of performance-based milestones. These milestones are generally categorized into three types; development milestones which are generally based on the advancement of our pipeline and initiation of clinical trials, regulatory milestones which are generally based on the submission, filing or approval of regulatory applications such as a new drug application in the United States, and commercialization milestones which are generally based on meeting specific thresholds of sales in certain geographic areas. If the achievement of a milestone is considered probable at the inception of the collaboration, the related milestone payment is included with other collaboration consideration, such as upfront fees and research funding, in our revenue model. Milestones that are tied to regulatory approval are not considered probable of being achieved until such approval is received. Milestones tied to counter-party performance are not included in our revenue model until the performance conditions are met. Upfront and ongoing development milestones are not subject to refund if the development activities are not successful. We perform an assessment to determine whether a substantive milestone exists at the inception of our collaborative arrangements. In evaluating if a milestone is substantive, we consider whether uncertainty exists as to the achievement of the milestone event at the inception of the arrangement, the achievement of the milestone involves substantive effort and can only be achieved based in whole or part on the performance or the occurrence of a specific outcome resulting from our performance, the amount of the milestone payment appears reasonable either in relation to the effort expected to be expended or to the projected enhancement of the value of the delivered items, there is any future performance required to earn the milestone, and the consideration is reasonable relative to all deliverables and payment terms in the arrangement. When a substantive milestone is achieved, the accounting rules permit us to recognize revenue related to the milestone payment in its entirety. To date, we have not recorded any substantive milestones under our collaborations because we have not identified any milestones that meet the required criteria listed above. We have deferred recognition of payments for achievement of non-substantive milestones and recognized revenue over the estimated period of performance applicable to each collaborative arrangement. As these milestones are achieved, we will recognize as revenue a portion of the milestone payment, which is equal to the percentage of the performance period completed when the milestone is achieved, multiplied by the amount of the milestone payment, upon achievement of such milestone. We will recognize the remaining portion of the milestone payment over the remaining performance period under the proportional performance method or on a straight-line basis. For revenue generating arrangements where we, as a vendor, provide consideration to a licensor or collaborator, as a customer, we apply the accounting standard that governs such transactions. This standard addresses the accounting for revenue arrangements where both the vendor and the customer make cash payments to each other for services and/or products. A payment to a customer is presumed to be a reduction of the selling price unless we receive an identifiable benefit for the payment and it can reasonably estimate the fair value of the benefit received. Payments to a customer that are deemed a reduction of selling price are recorded first as a reduction of revenue, to the extent of both cumulative revenue recorded to date and probable future revenues, which include any unamortized deferred revenue balances, under all arrangements with such customer, and then as an expense. Payments that are not deemed to be a reduction of selling price are recorded as an expense. We evaluate our collaborative agreements for proper classification in our consolidated statements of comprehensive loss based on the nature of the underlying activity. Transactions between collaborators recorded in our consolidated statements of comprehensive loss are recorded on either a gross or net basis, depending on the characteristics of the collaborative relationship. We generally reflect amounts due under our collaborative agreements related to cost-sharing of development activities as revenue. Amounts received prior to satisfying the above revenue recognition criteria are recorded as deferred revenue in the accompanying consolidated balance sheets. Although we follow detailed guidelines in measuring revenue, certain judgments affect the application of our revenue policy. For example, in connection with our existing collaboration agreements, we have recorded on our consolidated balance sheet short-term and long-term deferred revenue based on our best estimate of when such revenue will be recognized. Short-term deferred revenue consists of amounts that are expected to be recognized as revenue in the next 12 months. Amounts that we expect will not be recognized within the next 12 months are classified as long-term deferred revenue. However, this estimate is based on our current operating plan and, if our operating plan should change in the future, we may recognize a different amount of deferred revenue over the next 12-month period. The estimate of deferred revenue also reflects management’s estimate of the periods of our involvement in certain of our collaborations. Our performance obligations under these collaborations consist of participation on steering committees and the performance of other research and development services. In certain instances, the timing of satisfying these obligations can be difficult to estimate. Accordingly, our estimates may change in the future. Such changes to estimates would result in a change in revenue recognition amounts. If these estimates and judgments change over the course of these agreements, it may affect the timing and amount of revenue that we recognize and record in future periods. At December 31, 2015, we had short-term and long-term deferred revenue of $15.4 million and $53.0 million, respectively, related to our collaborations. Income Taxes We use the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured under enacted tax laws. A valuation allowance is required to offset any net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax asset will not be realized. We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. Our policy is to accrue interest and penalties related to unrecognized tax positions in income tax expense. As of December 31, 2015, we have not recorded significant interest and penalty expense related to uncertain tax positions. Research and Development Costs We expense research and development costs as incurred. Included in research and development costs are wages, benefits and other operating costs, facilities, supplies, external services, clinical trial and manufacturing costs, and overhead directly related to our research and development operations, as well as costs to acquire technology licenses. We have entered into several license agreements for rights to utilize certain technologies. The terms of the licenses may provide for upfront payments, annual maintenance payments, milestone payments based upon certain specified events being achieved and royalties on product sales. We charge costs to acquire and maintain licensed technology that has not reached technological feasibility and does not have alternative future use to research and development expense as incurred. During the years ended December 31, 2015, 2014 and 2013, we charged to research and development expense costs associated with license fees of $3.5 million, $12.1 million and $8.0 million, respectively. Accounting for Stock-Based Compensation We have stock incentive plans and an employee stock purchase plan under which we grant equity instruments. We account for all stock-based awards granted to employees at their fair value and generally recognize compensation expense over the vesting period of the award. Determining the amount of stock-based compensation to be recorded requires us to develop estimates of fair values of stock options as of the grant date. We calculate the grant date fair values using the Black-Scholes valuation model. Our expected stock price volatility assumption is based on the historical volatility of our publicly traded stock. For stock-based awards granted to non-employees, we generally recognize compensation expense over the vesting period of the award, which is generally the period during which services are rendered by such non-employees. At the end of each financial reporting period prior to vesting, we re-measure the value of these stock-based awards (as calculated using the Black-Scholes option-pricing model) using the then-current fair value of our common stock. Stock options granted by us to non-employees, other than members of our board of directors and scientific advisory board members, generally vest over the service period. The fair value of restricted stock awards granted to employees is based upon the quoted closing market price per share on the date of grant, adjusted for assumed forfeitures. Expense is recognized over the vesting period, commencing when we determine that it is probable that the awards will vest. For performance-based stock awards, expense is first recorded when we determine that the achievement of such performance conditions is deemed probable. This determination requires significant judgment by management. At the probable date, we record a cumulative expense catch-up, with remaining expense amortized over the remaining service period. Comprehensive Loss Comprehensive loss is comprised of net loss and certain changes in stockholders’ equity that are excluded from net loss. We include foreign currency translation adjustments in other comprehensive loss as the functional currency is not the United States dollar. We include unrealized gains and losses on certain marketable securities in other comprehensive loss. Net Loss Per Common Share We compute basic net loss per common share by dividing net loss by the weighted-average number of common shares outstanding. We compute diluted net loss per common share by dividing net loss by the weighted-average number of common shares and dilutive potential common share equivalents then outstanding. Potential common shares consist of shares issuable upon the exercise of stock options (using the treasury stock method), and unvested restricted stock awards. Because the inclusion of potential common shares would be anti-dilutive for all periods presented, diluted net loss per common share is the same as basic net loss per common share. The following table sets forth for the periods presented the potential common shares (prior to consideration of the treasury stock method) excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive, in thousands: At December 31, 2015 2014 2013 Options to purchase common stock 9,960 8,169 8,713 Unvested restricted common stock 19 30 500 9,979 8,199 9,213 Segment Information We operate in a single reporting segment, the discovery, development and commercialization of RNAi therapeutics. Subsequent Events We did not have any material recognized subsequent events. However, we did have the following nonrecognized subsequent event, which is more fully described in Note 7: • On February 10, 2016, we entered into an agreement to purchase land in Norton, Massachusetts for the construction of a manufacturing facility. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued a new revenue recognition standard which amends revenue recognition principles and provides a single, comprehensive set of criteria for revenue recognition within and across all industries. The new standard provides a five step framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures pertaining to revenue recognition in both interim and annual periods. In August 2015, the FASB deferred the effective date of the new revenue standard from January 1, 2017 to January 1, 2018. Early adoption is permitted any time after the original effective date, which for us is January 1, 2017. The standard allows for adoption using a full retrospective method or a modified retrospective method. We are currently evaluating the timing, method of adoption and the expected impact that the standard could have on our consolidated financial statements and related disclosures. In April 2015, the FASB amended its guidance on internal use software to clarify the accounting by customers for fees paid in a cloud computing arrangement. Under this guidance, if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for consistent with the customer’s accounting for other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. The new guidance became effective for us on January 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements and related disclosures. In November 2015, the FASB issued final guidance that requires companies to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. This guidance allows for adoption on either a prospective or retrospective basis. This guidance will be effective on January 1, 2017. Early adoption is permitted. We have elected to early adopt this guidance on a prospective basis and, as a result, prior consolidated balance sheets were not retrospectively adjusted. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In January 2016, the FASB issued new guidance on recognition and measurement of financial assets and financial liabilities. The new guidance will impact the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. All equity investments in unconsolidated entities (other than those accounted for under the equity method of accounting) will generally be measured at fair value with changes in fair value recognized through earnings. There will no longer be an available-for-sale classification (changes in fair value reported in other comprehensive income (loss)) for equity securities with readily determinable fair values. In addition, the FASB clarified the need for a valuation allowance on deferred tax assets resulting from unrealized losses on available-for-sale debt securities. In general, the new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings. This guidance will be effective for us on January 1, 2018. We are currently evaluating the expected impact that the standard could have on our consolidated financial statements and related disclosures. |

SIGNIFICANT AGREEMENTS | 3. SIGNIFICANT AGREEMENTS The following table summarizes our total consolidated net revenues from collaborators, for the periods indicated, in thousands: Year Ended December 31, 2015 2014 2013 Sanofi Genzyme $ 11,005 $ 369 $ — MDCO 10,301 10,753 4,604 Takeda 8,867 21,973 21,973 Monsanto 5,621 14,985 5,640 Cubist — — 9,721 Other 5,303 2,481 5,229 Total net revenues from collaborators $ 41,097 $ 50,561 $ 47,167 Product Alliances Sanofi Genzyme Collaboration In January 2014, we entered into a global, strategic collaboration with Sanofi Genzyme to discover, develop and commercialize RNAi therapeutics as Genetic Medicines to treat orphan diseases. The 2014 Sanofi Genzyme collaboration superseded and replaced the previous collaboration between us and Sanofi Genzyme entered into in October 2012 to develop and commercialize RNAi therapeutics targeting transthyretin, or TTR, for the treatment of TTR-mediated amyloidosis, or ATTR amyloidosis, including patisiran and revusiran, in Japan and the Asia-Pacific region. 2012 Sanofi Genzyme Agreement Under the 2012 Sanofi Genzyme agreement, Sanofi Genzyme paid us an upfront cash payment of $22.5 million. We were also entitled to receive certain milestone payments under the 2012 Sanofi Genzyme agreement. In the fourth quarter of 2013, we earned a milestone of $7.0 million based upon the completion of a successful patisiran Phase 2 clinical trial and a milestone of $4.0 million based upon the initiation of the Phase 3 clinical trial for patisiran. Under the 2012 Sanofi Genzyme agreement, the parties agreed to collaborate in the development and commercialization of licensed products, with Sanofi Genzyme assuming primary responsibility in the Sanofi Genzyme territory, which included Japan and the Asia-Pacific region, and us retaining primary responsibility in the rest of the world. We determined that the deliverables under the 2012 Sanofi Genzyme agreement included the license, a joint steering committee and any additional TTR-specific RNAi therapeutic compounds that comprised the ALN-TTR program. We also determined that, pursuant to the accounting guidance governing revenue recognition on multiple element arrangements, the license and undelivered joint steering committee and any additional TTR-specific RNAi therapeutic compounds did not have standalone value due to the specialized nature of the services to be provided by us. In addition, while Sanofi Genzyme had the ability to grant sublicenses, it could not sublicense all or substantially all of its rights under the 2012 Sanofi Genzyme agreement. The uniqueness of our services and the limited sublicense right were indicators that standalone value was not present in the arrangement. Therefore the deliverables were not separable and, accordingly, the license and undelivered services were treated as a single unit of accounting. We were unable to reasonably estimate the period of performance under the 2012 Sanofi Genzyme agreement, as we were unable to estimate the timeline of our deliverables related to the deliverable for any additional TTR-specific RNAi therapeutic compounds. Through December 31, 2013, we had deferred all revenue, or $33.5 million, under the 2012 Sanofi Genzyme agreement. 2014 Sanofi Genzyme Collaboration In January 2014, we entered into the 2014 Sanofi Genzyme collaboration. As noted above, the 2014 Sanofi Genzyme collaboration superseded and replaced the 2012 Sanofi Genzyme agreement. The 2014 Sanofi Genzyme collaboration is structured as an exclusive relationship for the worldwide development and commercialization of RNAi therapeutics in the field of Genetic Medicines, which includes our current and future Genetic Medicine programs that reach Human Proof-of-Principle Study Completion (as defined in the Sanofi Genzyme master agreement), or Human POP, by the end of 2019, subject to extension to the end of 2021 in various circumstances. We will retain product rights in North America and Western Europe, referred to as the Alnylam Territory, while Sanofi Genzyme will obtain exclusive rights to develop and commercialize collaboration products in the rest of the world, referred to as the Sanofi Genzyme Territory, together with certain broader co-development/co-promote or worldwide rights for certain products. Sanofi Genzyme’s rights, described in detail below, are structured as an opt-in that is triggered upon achievement of Human POP. We maintain development control for all programs prior to Sanofi Genzyme’s opt-in and maintain development and commercialization control after Sanofi Genzyme’s opt-in for all programs in the Alnylam Territory. Specifically, in addition to its regional rights for our current and future Genetic Medicine programs in the Sanofi Genzyme Territory, Sanofi Genzyme has the right to either (i) co-develop and co-promote fitusiran for the treatment of hemophilia and other rare bleeding disorders in the Alnylam Territory, with us maintaining development and commercialization control, or (ii) obtain a global license to ALN-AS1 for the treatment of hepatic porphyrias. Sanofi Genzyme may exercise this selection right upon the completion of Human POP for both the fitusiran and ALN-AS1 programs. Finally, Sanofi Genzyme has the right for a global license to a single, future Genetic Medicine program that was not one of our defined Genetic Medicine programs as of the effective date of the 2014 Sanofi Genzyme collaboration. We will retain global rights to any RNAi therapeutic Genetic Medicine program that does not reach Human POP by the end of 2019, subject to certain limited exceptions. We retain full rights to all current and future RNAi therapeutic programs outside of the field of Genetic Medicines, including the right to form new collaborations. Under the 2014 Sanofi Genzyme collaboration, Sanofi Genzyme’s specific license rights and the programs into which Sanofi Genzyme has opted include the following: • Regional license terms and programs — Upon opt-in, we will retain product rights in the Alnylam Territory, while Sanofi Genzyme will obtain exclusive rights to develop and commercialize the product in the Sanofi Genzyme Territory. Sanofi Genzyme can elect this license for any of our current and future Genetic Medicine programs that complete Human POP by the end of 2019, subject to limited extension. Development costs for products once Sanofi Genzyme exercises an option will be shared between Sanofi Genzyme and us, with Sanofi Genzyme responsible for twenty percent of the global development costs. Upon the effective date of the 2014 Sanofi Genzyme collaboration, Sanofi Genzyme expanded the scope of its regional license and collaboration for patisiran, an investigational RNAi therapeutic currently in a Phase 3 clinical trial, which was originally established under the 2012 Sanofi Genzyme agreement. In September 2015, Sanofi Genzyme elected to opt into our fitusiran clinical development program for the treatment of hemophilia and other rare bleeding disorders under the regional license terms. As described above, Sanofi Genzyme retains its future opt-in right to co-develop and co-promote fitusiran in the Alnylam Territory pursuant to the co-development/co-promote license terms described below. Cost-sharing for the fitusiran program began in January 2016. Sanofi Genzyme will be required to make payments totaling up to $50.0 million upon the achievement of certain patisiran development milestones. We could potentially earn the next patisiran milestone payment, ranging between $5.0 million and $20.0 million based on the geographic region, upon the achievement of specified events in connection with a regulatory filing or approval. In addition, Sanofi Genzyme will be required to make payments totaling up to $75.0 million per product other than patisiran, including fitusiran, consisting of up to $55.0 million in development milestones and $20.0 million in commercial milestones. We could potentially earn the first fitusiran milestone payment of $25.0 million based upon the initiation of the first global Phase 3 clinical trial for fitusiran. Sanofi Genzyme will also be required to pay tiered double-digit royalties up to twenty percent for each regional product based on annual net sales, if any, of such regional product by Sanofi Genzyme, its affiliates and sublicensees. • Co-development/co-promote license terms and programs — Upon opt-in, we will retain product rights in the Alnylam Territory, while Sanofi Genzyme will obtain exclusive rights to develop and commercialize the product in the Sanofi Genzyme Territory, and will co-promote the product in the Alnylam Territory. Upon the effective date of the 2014 Sanofi Genzyme collaboration, Sanofi Genzyme expanded its regional rights for revusiran, an investigational RNAi therapeutic currently in a Phase 3 clinical trial, which were originally granted under the 2012 Sanofi Genzyme agreement, to include a co-development/co-promote license and collaboration. As noted above, Sanofi Genzyme also has the right to elect a co-development/co-promote license and collaboration for fitusiran, if it does not elect a global license and collaboration for ALN-AS1. Development costs for co-development/co-promote products, once Sanofi Genzyme exercises an option, will be shared between Sanofi Genzyme and us, with Sanofi Genzyme responsible for fifty percent of the global development costs. Sanofi Genzyme will be required to make payments totaling up to $75.0 million in development milestones for revusiran and, if selected, fitusiran. In December 2014, we earned a development milestone payment of $25.0 million based upon the initiation of the first global Phase 3 clinical trial for revusiran. We could potentially earn the next revusiran milestone payment, ranging between $5.0 million and $25.0 million based on the geographic region, upon the achievement of specified events in connection with regulatory approval. Sanofi Genzyme will also be required to pay tiered double-digit royalties up to twenty percent for each co-development/co-promote product based on annual net sales, if any, in the Sanofi Genzyme Territory for such co-development/co-promote product by Sanofi Genzyme, its affiliates and sublicensees. The parties will share profits equally and we expect to book product sales in the Alnylam Territory. • Global license terms and programs — Upon opt-in, Sanofi Genzyme will obtain a worldwide license to develop and commercialize the product. Sanofi Genzyme can elect a global license for ALN-AS1, if it does not elect a co-development/co-promote license for fitusiran, as described above. Sanofi Genzyme will also have one right to a global license through 2019, subject to limited extension, for a future Genetic Medicine program that was not one of our defined Genetic Medicine programs as of the effective date of the 2014 Sanofi Genzyme collaboration. Sanofi Genzyme shall be responsible for one hundred percent of global development costs. Sanofi Genzyme will be required to make payments totaling up to $200.0 million per global product, including up to $60.0 million in development milestones and $140.0 million in commercial milestones. Sanofi Genzyme will also be required to pay tiered double-digit royalties up to twenty percent for each global product based on annual net sales, if any, of each global product by Sanofi Genzyme, its affiliates and sublicensees. Due to the uncertainty of pharmaceutical development and the high historical failure rates generally associated with drug development, we may not receive any additional milestone payments or any royalty payments from Sanofi Genzyme under the 2014 Sanofi Genzyme collaboration. Under the master agreement, the parties will collaborate in the development of option products, with us leading development for all programs prior to Sanofi Genzyme’s opt-in and also leading development and commercialization for all programs in the Alnylam Territory after Sanofi Genzyme’s opt-in. If Sanofi Genzyme does not exercise its option to license rights to a particular program, we will retain the exclusive right to develop and commercialize such program throughout the world, including the right to sublicense to third parties. The 2014 Sanofi Genzyme collaboration is governed by an alliance joint steering committee that is comprised of an equal number of representatives from each party. There are additional committees to manage various aspects of each regional, co-developed/co-promoted and global program. We and Sanofi Genzyme intend to enter into supply agreements to provide for supply of collaboration products to Sanofi Genzyme for clinical studies, and, at Sanofi Genzyme’s request, commercial sales. Sanofi Genzyme also has certain rights to manufacture collaboration products. Additionally, Sanofi Genzyme has certain limited opt-out rights, as specified in the master agreement, upon which products revert fully back to us with no further obligations to Sanofi Genzyme. The master agreement (including the license terms appended thereto) contains certain termination provisions, including for material breach by the other party. Unless terminated earlier pursuant to its terms, the master agreement will terminate upon the last to expire of any of the option periods under the master agreement or the license terms appended thereto. Upon the closing of the equity transaction in February 2014, we sold to Sanofi Genzyme 8,766,338 shares of our common stock and Sanofi Genzyme paid $700.0 million in aggregate cash consideration to us. As a condition to the closing of the equity transaction, Sanofi Genzyme entered into an investor agreement with us. Under the investor agreement, until the earlier of the fifth anniversary of the expiration or earlier termination of the 2014 Sanofi Genzyme collaboration and the date on which Sanofi Genzyme and its affiliates cease to beneficially own at least 5% of our outstanding common stock, Sanofi Genzyme and its affiliates are bound by certain “standstill” provisions. The standstill provisions include agreements not to acquire more than 30% of our outstanding common stock, call stockholder meetings, nominate directors other than those approved by our board of directors, subject to certain limited exceptions, or propose or support a proposal to acquire us. Further, Sanofi Genzyme has agreed to vote, and cause its affiliates to vote, all shares of our voting securities they are entitled to vote, up to a maximum of 20% of our outstanding common stock, in a manner either as recommended by our board of directors or proportionally with the votes cast by our other stockholders, except with respect to certain change of control transactions or our liquidation or dissolution. Until Sanofi Genzyme owns less than 7.5% of our outstanding common stock, subject to Sanofi Genzyme’s limited right to maintain its ownership percentage as described below, if we issue common stock or securities convertible into or exercisable for common stock to a third party that holds at least 30% of our outstanding common stock or, in connection with a collaboration or license transaction, to a third party that will initially hold at least the percentage of our outstanding common stock represented by the shares purchased by Sanofi Genzyme at the closing of the equity transaction, we will offer Sanofi Genzyme an opportunity to amend the standstill and voting provisions in the investor agreement to be consistent with the terms provided to such third party. Under the investor agreement, Sanofi Genzyme has also agreed not to dispose of any shares of common stock beneficially owned by it immediately after the closing of the stock purchase until the earlier of (i) December 31, 2019 (subject to extension by up to two years if Sanofi Genzyme’s option to select additional compounds under the master agreement is extended beyond December 31, 2019) and (ii) six months after the expiration or earlier valid termination of the collaboration, in each case subject to earlier termination in the event certain clinical activities under the collaboration fail to occur. Following the expiration of this lock-up period, Sanofi Genzyme will be permitted to sell such shares of common stock subject to certain limitations, including volume and manner of sale restrictions. Notwithstanding the foregoing, following the two-year anniversary of the closing of the stock purchase, in the event that the market price per share of our common stock is at least 100% higher than the market price per share of our common stock at closing of the stock purchase (in each case based upon a ten-day trailing average), Sanofi Genzyme may sell up to 25% of its initial shares, subject to certain restrictions on post-lock-up period dispositions as described above. Under the investor agreement, following the lock-up period, Sanofi Genzyme will have three demand rights to require us to conduct a registered underwritten public offering with respect to the shares of common stock beneficially owned by Sanofi Genzyme immediately after the closing of the stock purchase, subject to certain conditions. In addition, following the lock-up period, subject to certain conditions, Sanofi Genzyme will be entitled to participate in registered underwritten public offerings by us if other selling stockholders are included in the registration. The investor agreement provides that, until Sanofi Genzyme owns less than 7.5% of our outstanding common stock, subject to Sanofi Genzyme’s limited right to maintain its ownership percentage as described herein, in connection with new issuances of common stock, subject to certain exceptions, Sanofi Genzyme will be entitled to a right of first offer to participate proportionally to maintain its then-current ownership percentage of our common stock. If Sanofi Genzyme is not entitled to a right of first offer with respect to a new issuance, Sanofi Genzyme will have the opportunity, on a post-transaction basis, to purchase additional shares sufficient to maintain its pre-transaction ownership percentage of our common stock (subject to the same 7.5% ownership threshold). Finally, in the event Sanofi Genzyme and its affiliates acquire at least 20% or more of our outstanding common stock, Sanofi Genzyme will be entitled to appoint one individual to our board of directors. Sanofi Genzyme will also be entitled to certain information rights, including with respect to financial information in the event Sanofi Genzyme or its affiliates require such information for its own financial reporting purposes. The rights and restrictions under the investor agreement are subject to termination upon the occurrence of certain events. We recorded the issuance of 8,766,338 shares of our common stock under the stock purchase agreement using the price of our common stock on the date the shares were issued to Sanofi Genzyme. Based on the common stock price of $85.72, the fair value of the shares issued was $751.5 million, which was $51.5 million in excess of the proceeds received from Sanofi Genzyme for the issuance of our common stock. This $51.5 million is being amortized on a straight-line basis over the performance period, which is currently approximately six years as described below. In addition, due to intraperiod tax allocation rules, upon closing of the equity transaction we recorded a benefit from income taxes of $15.2 million due to the Sanofi Genzyme equity purchase being recorded in additional paid-in capital, net of tax. For the year ended December 31, 2014, we recorded a cumulative benefit from income taxes of $20.7 million. In accordance with the investor agreement, as a result of our issuance of shares in connection with our acquisition of Sirna Therapeutics, Inc., or Sirna, in March 2014, Sanofi Genzyme exercised its right to purchase an additional 344,448 shares of our common stock for $23.0 million. In addition, in January 2015, in connection with our public offering, Sanofi Genzyme exercised its right to purchase directly from us, in concurrent private placements, 744,566 shares of common stock at the public offering price resulting in $70.7 million in proceeds to us. The sales of common stock to Sanofi Genzyme were not registered as part of the public offering, though they were consummated simultaneously with the public offering. Sanofi Genzyme also has the right at the beginning of each year to purchase a number of shares of our common stock based on the number of shares we issued during the previous year for compensation-related purposes. Sanofi Genzyme exercised this right to purchase directly from us 196,251 shares of our common stock on January 22, 2015 for $18.3 million and 205,030 shares of our common stock on February 1, 2016 for $14.3 million. The sales of these shares to Sanofi Genzyme were consummated as private placements. In each instance, the purchase by Sanofi Genzyme described above allowed Sanofi Genzyme to maintain its ownership level of our common stock of approximately 12%. We determined that the deliverables for the programs on which Sanofi Genzyme was collaborating with us upon initiation of the 2014 collaboration included the licenses to our patisiran and revusiran clinical programs, which licenses were delivered to Sanofi Genzyme upon the closing date of the transaction, and the associated development activities, joint steering committee participation and information exchange for these clinical programs. We also determined that, pursuant to the accounting guidance governing revenue recognition on multiple element arrangements, the license and associated undelivered development activities, joint steering committee participation and information exchange activities did not have standalone value due to the specialized nature of the services to be provided by us. In addition, while Sanofi Genzyme has the ability to grant sublicenses, it cannot sublicense all or substantially all of its rights under the 2014 Sanofi Genzyme collaboration. The uniqueness of our services and the limited sublicense rights are indicators that standalone value is not present in the arrangement. Therefore the deliverables are not separable and, accordingly, the license and undelivered services were treated as a single unit of accounting. When multiple deliverables are accounted for as a single unit of accounting, we base our revenue recognition model on the final deliverable. Under the 2014 Sanofi Genzyme collaboration, the last deliverables for patisiran and revusiran are expected to be completed within approximately six years from the closing date of the transaction. We determined that the total cash received from Sanofi Genzyme under the now superseded 2012 Sanofi Genzyme agreement reflects consideration for certain of the performance obligations for ALN-TTR programs included in the 2014 Sanofi Genzyme collaboration. Therefore we are recognizing the $33.5 million of deferred revenue under the 2012 Sanofi Genzyme agreement on a straight-line basis over the period of performance of the ALN-TTR programs, which, as noted above, is currently approximately six years. In addition, during the fourth quarter of 2014, we recognized as revenue a portion of the $25.0 million milestone payment earned in December 2014 equal to the percentage of the performance period completed when the milestone was earned. During the year ended December 31, 2015, we also recognized as revenue a portion of the expense reimbursement of $33.9 million due to us under the terms of the 2014 Sanofi Genzyme collaboration equal to the percentage of the performance period completed to date. As future consideration is achieved, including any milestones or reimbursement for development activities, we will recognize as revenue a portion of these payments equal to the percentage of the performance period completed when the milestone or activities have been satisfied, multiplied by the amount of the payment. We will recognize the remaining portion of consideration received over the remaining performance period on a straight-line basis. At December 31, 2015, deferred revenue under the 2014 Sanofi Genzyme collaboration was $29.5 million. We determined that the opt-in rights that Sanofi Genzyme has for future Genetic Medicine programs represent separate and additional deliverables that Sanofi Genzyme may receive from us in future periods. Upon each opt-in by Sanofi Genzyme, we have determined that each program and the related activities will represent a single unit of accounting and, consistent with our accounting policies, we will base our revenue recognition period on the final deliverable associated with each future opt-in, including fitusiran, where we began earning revenue, including cost reimbursement and potential milestones, in January 2016. The Medicines Company Alliance In February 2013, we and MDCO entered into a license and collaboration agreement pursuant to which we granted to MDCO an exclusive, worldwide license to develop, manufacture and commercialize RNAi therapeutics targeting PCSK9 for the treatment of hypercholesterolemia and other human diseases, including ALN-PCSsc. MDCO paid us an upfront cash payment of $25.0 million. Upon achievement of certain events, we will be entitled to receive milestone payments, up to an aggregate of $180.0 million, including up to $30.0 million in specified development milestones, $50.0 million in specified regulatory milestones and $100.0 million in specified commercialization milestones. In addition, we will be entitled to royalties ranging from the low- to high- teens based on annual worldwide net sales, if any, of licensed products by MDCO, its affiliates and sublicensees, subject to reduction under specified circumstances. In December 2014, we earned a development milestone payment of $10.0 million under the MDCO agreement based upon the initiation of our Phase 1 clinical trial for ALN-PCSsc. In addition, in 2015 and 2014, we were reimbursed $3.8 million and $4.8 million, respectively, for costs incurred for certain development activities. We could potentially earn the next development milestone payment of $20.0 million based upon the initiation of a pivotal study for ALN-PCSsc. Due to the uncertainty of pharmaceutical development and the high historical failure rates generally associated with drug development, we may not receive any additional milestone payments or any royalty payments from MDCO. Under the MDCO agreement, we and MDCO will collaborate in the further development of ALN-PCSsc. We had responsibility for the development of ALN-PCSsc until Phase 1 Completion, as defined in the MDCO agreement, at our cost, up to an agreed upon initial development cost cap. In late 2015, MDCO assumed responsibility for all development and commercialization of ALN-PCSsc, at its sole cost. The collaboration between us and MDCO is governed by a joint steering committee comprised of an equal number of representatives from each party. We were solely responsible for obtaining supply of finished product reasonably required for the conduct of our obligations under the initial development plan through Phase 1 Completion, and are responsible for supplying MDCO with finished product reasonably required for the first Phase 2 clinical trial of ALN-PCSsc conducted by MDCO, at our expense, provided such costs do not exceed the development costs cap, subject to certain exceptions. After such time, MDCO will have the sole right and responsibility to manufacture and supply ALN-PCSsc for development and commercialization under the MDCO development plan, subject to the terms of the MDCO agreement. We and MDCO intend to enter into a supply and technical transfer agreement to provide for supply of ALN-PCSsc to MDCO. Unless terminated earlier in accordance with the terms of the agreement, the MDCO Agreement expires on a licensed product-by-licensed product and country-by-country basis upon expiration of the last royalty term for any licensed product in any country, where a royalty term is defined as the latest to occur of (1) the expiration of the last valid claim of patent rights covering a licensed product, (2) the expiration of the Regulatory Exclusivity, as defined in the MDCO Agreement, and (3) the twelfth anniversary of the first commercial sale of the licensed product in such country. We estimate that our fundamental RNAi patents covering licensed products under the MDCO Agreement will expire both in and outside of the United States generally between 2016 and 2028. We also estimate that our ALN-PCS product-specific patents covering licensed products under the MDCO Agreement in the United States and elsewhere will expire at the end of 2033. These patent rights are subject to potential patent term extensions and/or supplemental protection certificates extending such terms in countries where such extensions may become available. In addition, more patent filings relating to the collaboration may be made in the future. Either party may terminate the MDCO Agreement in the event the other party fails to cure a material breach or upon patent-related challenges by the other party. In addition, MDCO has the right to terminate the agreement without cause at any time upon four months’ prior written notice. During the term of the MDCO agreement, neither party will, alone or with an affiliate or third party, research, develop or commercialize, or grant a license to any third party to research, develop or commercialize, in any country, any product directed to the PCSK9 gene, other than a licensed product, without the prior written agreement of the other party, subject to the terms of the MDCO agreement. We have determined that the significant deliverables under the MDCO agreement include the license, the joint steering committee, technology transfer obligations, development activities through Phase 1 Completion and supply of product for a Phase 2 clinical trial. We also determined that, pursuant to the accounting guidance governing revenue recognition on multiple element arrangements, the license and collective undelivered activities and services do not have standalone value due to the specialized nature of the activities and services to be provided by us. In addition, while MDCO has the ability to grant sublicenses, it must receive our prior written consent to sublicense all or substantially all of its rights. The uniqueness of our services and the limited sublicense right are indicators that standalone value is not present in the arrangement. Therefore the deliverables are not separable and, accordingly, the license and undelivered services are being treated as a single unit of accounting. When multiple deliverables are accounted for as a single unit of accounting, we base our revenue recognition pattern on the final deliverable. Under the MDCO agreement, all deliverables are expected to be completed within five years. We are recognizing revenue under the MDCO agreement on a straight-line basis over five years. We are not utilizing a proportional performance model since we are unable to reasonably estimate the level of effort to fulfill these obligations, primarily because the effort required under the development activities is largely unknown. We received the upfront payment of $25.0 million from MDCO in February 2013, which was initially recorded as deferred revenue. During the fourth quarter of 2014, we recognized as revenue a portion of the $10.0 million milestone payment earned in December 2014 equal to the percentage of the performance period completed when the milestone was earned. During 2015 and 2014, we also recognized as revenue a portion of the $3.8 million and $4.8 million, respectively, of expense reimbursement due to us under the terms of the MDCO agreement equal to the percentage of the performance period completed upon the invoice date. As future consideration, including any milestones or reimbursement for development activities, are earned, we will recognize as revenue a portion of these payments equal to the percentage of the performance period completed when the milestone is achieved or service has been provided, multiplied by the amount of the payment. We will recognize the remaining portion of consideration received over the remaining performance period on a straight-line basis. At December 31, 2015, deferred revenue under the MDCO agreement was $18.3 million. Platform Alliances Monsanto Alliance In August 2012, we and Monsanto entered into a license and collaboration agreement, pursuant to which we granted to Monsanto a worldwide, exclusive, royalty bearing right and license, including the right to grant sublicenses, to our RNAi platform technology and intellectual property controlled by us as of the date of the Monsanto agreement o |

COMMITMENTS AND CONTINGENCIES | 7. COMMITMENTS AND CONTINGENCIES Purchase Commitments We have future purchase commitments totaling $150.2 million at December 31, 2015, of which $87.5 million is expected to be incurred in 2016 and $62.7 million is expected to be incurred past 2016. These commitments are related to purchase orders, clinical and pre-clinical agreements, and other purchase commitments for goods or services that we are likely to continue, regardless of the fact that they were cancelable at December 31, 2015. Technology License Commitments We have licensed from third parties the rights to use certain technologies in our research processes as well as in any products we may develop including these licensed technologies. In accordance with the related license agreements, we are required to make certain fixed payments to the licensor or a designee of the licensor over various agreement terms. Many of these agreement terms are consistent with the remaining lives of the underlying intellectual property that we have licensed. At December 31, 2015, we were committed to make the following fixed, estimated and cancelable payments under existing license agreements, in thousands: Year Ending December 31, 2016 $ 8,734 2017 741 2018 751 2019 761 2020 761 Thereafter 7,819 Total $ 19,567 We in-license technology from a number of sources, including Ionis and Merck. Pursuant to these in-license agreements, we will be required to make additional payments if and when we achieve specified development, regulatory and commercialization milestones. To the extent we are unable to reasonably predict the likelihood, timing or amount of such payments, we have excluded them from the table above. Facility Leases 300 Third Street We lease office and laboratory space located at 300 Third Street, Cambridge, Massachusetts, for our corporate headquarters and primary research facility under a non-cancelable real property lease agreement, or the Third Street Lease, with ARE-MA Region No. 28 LLC, or the Landlord. Under the Third Street Lease, we lease a total of approximately 129,000 square feet of office and laboratory space. The term of the Third Street Lease was set to expire in September 2016. In March 2014, we and the Landlord amended the Third Street Lease to extend the term for an additional five years, through September 30, 2021. Under the amended Third Street Lease, we have the option to extend the term for one additional five-year period. 665 Concord Avenue On February 10, 2012, we entered into a non-cancelable real property lease agreement, or the BMR-665 Concord Avenue Lease, with BMR-Fresh Pond Research Park LLC for our manufacturing facility for patisiran formulated bulk drug product. Under the BMR-665 Concord Avenue Lease, we lease approximately 15,000 square feet of office and laboratory space located at 665 Concord Avenue, Cambridge, Massachusetts. The term of the BMR Lease expires August 31, 2017. We have the option to extend the BMR-665 Concord Avenue Lease for two successive five-year periods. 675 West Kendall Street In April 2015, we entered into a non-cancelable real property lease, or the BMR-675 West Kendall lease, with BMR-675 West Kendall Street, LLC, or BMR, for laboratory and office space located at 675 West Kendall Street, Cambridge, Massachusetts. We intend to move our corporate headquarters to this location in early 2019. Under the terms of the BMR-675 West Kendall lease, we will lease approximately 295,000 square feet of laboratory and office space. The term of the BMR-675 West Kendall lease will commence on May 1, 2018 and rent payments will become due commencing upon substantial completion of the building improvements, which is currently expected to be on or around February 1, 2019, and will continue for 15 years from the rent commencement date, with options to renew for two terms of five years each, subject to the terms of the BMR-675 West Kendall lease. Annual rent under the BMR-675 West Kendall lease, exclusive of operating expenses and real property taxes, will be $19.8 million for the first year, with annual increases of 3% thereafter. Under the terms of the BMR-675 West Kendall lease, BMR will contribute a total of $56.1 million toward the cost of base building and tenant improvements. Under the terms of the BMR-675 West Kendall lease, for so long as we lease and occupy 70% or more of the rentable area of the leased premises and there are at least ten years remaining on the term of the BMR-675 West Kendall lease, we have a one-time right of first offer as to all of the rentable space in the building at 500 Kendall Street, Cambridge, Massachusetts, that is available for lease after the lease for such space that is currently in effect expires or terminates. 101 Main Street In May 2015, we entered into a non-cancelable real property lease agreement with RREEF America REIT II CORP. PPP, or RREEF, for office space located on several floors at 101 Main Street, Cambridge, Massachusetts. This lease supplements the initial lease entered into in March 2015 between us and RREEF for office space on a separate floor at the 101 Main Street location. Under the terms of the 101 Main Street leases, we will lease approximately 72,000 square feet of office space at the 101 Main Street location. The terms of the initial 101 Main Street lease and the additional 101 Main Street lease commenced in March 2015 and January 2016, and continue for four years, with an option to renew for one five-year term, and five and a half years, with an option to renew for one five-year term, respectively. Initial annual rent for the initial lease and the additional lease, exclusive of operating expenses and real property taxes, will be $1.7 million and $3.5 million, respectively, with annual increases of $1/square foot under each lease thereafter. Rent payments commenced in May 2015 under the initial lease and we expect rent payments to commence in May 2016 under the additional lease. We received $0.4 million, $1.9 million and $0.2 million in leasehold improvement incentives during the years ended December 31, 2015, 2014 and 2013, respectively. These leasehold improvement incentives are being accounted for as a reduction in rent expense ratably over the lease term. The balance from these leasehold improvement incentives is included in current portion of deferred rent and deferred rent, net of current portion, in the consolidated balance sheets at December 31, 2015 and 2014. We had $1.5 million in restricted cash that is recorded in long-term other assets as of December 31, 2015 in connection with an irrevocable standby letter of credit with RREEF. Our facility leases described above generally contain customary provisions allowing the landlords to terminate the leases if we fail to remedy a breach of any of our obligations under any such lease within specified time periods, or upon our bankruptcy or insolvency. Total rent expense, including operating expenses, under our real property leases was $10.5 million, $8.9 million and $4.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. Future minimum payments under our non-cancelable facility leases are approximately as follows, in thousands: Year Ending December 31, 2016 $ 11,521 2017 13,152 2018 13,055 2019 30,955 2020 33,035 Thereafter 350,148 Total $ 451,866 Other On February 10, 2016, we entered into an agreement with 20 Commerce LLC to purchase 12 acres of undeveloped land in Norton, Massachusetts for an aggregate of approximately $8.0 million in cash payable for the land and related acquisition costs. We anticipate constructing a manufacturing facility at this site for clinical and commercial drug products. The closing of the transaction is subject to the completion of due diligence on the property and the satisfaction or waiver of other customary closing conditions. We expect the transaction to close in the first quarter of 2016. Litigation University of Utah Litigation On March 22, 2011, The University of Utah, or Utah, filed a civil complaint in the United States District Court for the District of Massachusetts, or the MA District Court, against us, Max Planck Gesellschaft Zur Foerderung Der Wissenschaften e.V. and Max Planck Innovation GmbH, together, Max Planck, the Whitehead Institute for Biomedical Research, or Whitehead, the Massachusetts Institute of Technology, or MIT, and the University of Massachusetts, or UMass, claiming a professor at Utah is the sole inventor or, in the alternative, a joint inventor, of the Tuschl patents. Utah was seeking changes to the inventorship of the Tuschl patents, unspecified damages and other relief. On October 31, 2011, we, Max Planck, Whitehead, MIT and UMass filed a motion to dismiss. Also on October 31, 2011, UMass filed a motion to dismiss on separate grounds, which we, Max Planck, Whitehead and MIT joined. On December 31, 2011, Utah filed a second amended complaint dropping UMass as a defendant and adding as defendants several UMass officials. In June 2012, the MA District Court denied both motions to dismiss. We, Max Planck, Whitehead, MIT and UMass filed an appeal of the MA District Court’s ruling on the motion to dismiss for lack of jurisdiction and a motion requesting that the MA District Court stay the case pending the outcome of the appeal. In July 2012, the MA District Court stayed discovery in the case pending the outcome of the defendants’ appeal. In August 2013, the United States Court of Appeals for the Federal Circuit, or CAFC, affirmed the lower court’s ruling, in a split decision. In September 2013, we filed a petition with the CAFC for rehearing or rehearing en banc. In November 2013, the CAFC denied our petition for rehearing or rehearing en banc and remanded the case back to the MA District Court. In February 2014, we filed a petition for writ of certiorari from the Supreme Court and a motion to stay the lower court proceedings pending a decision from the Supreme Court on our petition. The MA District Court granted our motion to stay the proceedings, however, in June 2014 the Supreme Court denied our petition for certiorari and remanded the case back to the MA District Court for trial, which was scheduled to begin in November 2015. On March 30, 2015, Utah voluntarily dismissed its sole inventorship claims leaving joint inventorship and state law damages claims pending. Utah subsequently clarified that such dismissal was with prejudice. On March 31, 2015, we filed motions for summary judgment seeking dismissal of all remaining claims. An oral hearing on these motions was held on July 13, 2015. On September 28, 2015, the MA District Court granted both of our motions for summary judgment, finding that there was no collaboration between Dr. Bass and Dr. Tuschl, which is a pre-requisite for co-inventorship, and dismissing Utah’s state law damages claims as well. On October 28, 2015, Utah filed a notice of appeal to the CAFC. On December 18, 2015, the CAFC for the Federal Circuit entered an order dismissing Utah’s appeal following a joint motion filed by us and Utah seeking dismissal of the appeal with prejudice. This disposed of Utah’s inventorship claims and its state law claims for damages. On October 14, 2015, we filed a motion with the MA District Court seeking reimbursement of costs and fees associated with defending this action in the amount of approximately $8.0 million. On November 30, 2015, the MA District Court dismissed our motion and on December 15, 2015, we filed a notice of appeal of this ruling with the CAFC. While we believe a fee award is merited in this case, such awards are made at the discretion of the court. We anticipate a ruling on this motion in mid-2016, however, the timing will be determined by the court. Dicerna Litigation On June 10, 2015, we filed a trade secret misappropriation lawsuit against Dicerna Pharmaceuticals, Inc., or Dicerna, in the Superior Court of Middlesex County, Massachusetts, seeking to stop misappropriation by Dicerna of our confidential, proprietary and trade secret information related to the RNAi assets we purchased from Merck, including certain GalNAc conjugate technology. In addition to permanent injunctive relief, we are also seeking monetary damages from Dicerna. On July 10, 2015, Dicerna filed its answer to our complaint, in which it denied our claims, along with initial discovery requests, to which we responded in a timely fashion. On July 27, 2015, Dicerna filed a motion seeking removal of the case to the Business Litigation Session of the Superior Court of Suffolk County, which we opposed. On August 31, 2015, the Court denied Dicerna’s motion. A protective order has been agreed to by us and Dicerna and was entered by the Court on November 12, 2015. Discovery is ongoing with us and Dicerna. We intend to request a scheduling conference with the Court in the first quarter of 2016 to set a discovery schedule and trial date. Although we believe we have meritorious claims in this matter, litigation is subject to inherent uncertainty and a court could ultimately rule against us. In addition, litigation and related matters are costly and may divert the attention of our management and other resources that would otherwise be engaged in other activities. Our accounting policy for accrual of legal costs is to recognize such expenses as incurred. Arbutus Settlement Agreement On November 12, 2012, we, Arbutus Biopharma Corporation, or ABC (formerly Tekmira Pharmaceuticals Corporation), Protiva Biotherapeutics, Inc., a wholly owned subsidiary of ABC, and together with ABC, referred to as Arbutus, and Acuitas Therapeutics Inc., or Acuitas (formerly AlCana Technologies, Inc.), entered into a settlement agreement and general release resolving all ongoing litigation, as well as a patent interference proceeding between us and Arbutus. The terms of the settlement agreement include mutual releases and dismissal with prejudice of all claims and counterclaims between the parties. In addition, as part of the settlement agreement, the parties agreed to a covenant not to sue one another in the future on matters released under the settlement agreement, as well as substantial liquidated damages to be paid by any party that breaches such covenant. The parties also agreed to resolve any future disputes that may arise over the three years following the settlement through binding arbitration. Pursuant to the settlement agreement, we and Arbutus also agreed to resolve the interference proceeding declared by the United States Board of Patent Appeals and Interferences between us and Arbutus, captioned Protiva Biotherapeutics, Inc. v. Alnylam Pharmaceuticals, Inc., Patent Interference No. 105792. Contemporaneously with the execution of the settlement agreement, we and Arbutus restructured our contractual relationship and entered into a cross-license agreement that superseded the prior license and manufacturing agreements among us, ABC and Arbutus. In connection with this restructuring, we incurred a $65.0 million charge to operating expenses for the year ended December 31, 2012. Specifically, we made a one-time payment of $30.0 million to Arbutus for the termination of, and our release from, all of our obligations under the manufacturing agreement with ABC, including without limitation the obligations to obtain materials and/or services from ABC. Further, we elected to buy-down certain future potential milestone and royalty payments due to Arbutus for certain of our RNAi therapeutics, formulated using lipid nanoparticle, or LNP, technology. Specifically, pursuant to the cross-license agreement, we made a one-time payment of $35.0 million to Arbutus, which amount constituted payment for the termination of the 2008 license agreements with ABC and Arbutus and the parties’ rights and obligations thereunder, as well as the buy-down of certain milestone payments and the significant reduction of royalty rates for ALN-VSP, ALN-PCS02 and patisiran. In addition, under the 2012 cross-license agreement, we were obligated to pay ABC an aggregate of $10.0 million in contingent milestone payments related to advancement of ALN-VSP and patisiran, which now represent the only potential milestones due to Arbutus for ALN-VSP, ALN-PCS02 and patisiran LNP-based RNAi therapeutics. In the fourth quarter of 2013, we paid ABC $5.0 million in connection with the initiation of the patisiran Phase 3 clinical trial. With respect to the second $5.0 million milestone, in August 2013, we initiated binding arbitration proceedings to resolve a disagreement with ABC regarding the achievement by ABC of this milestone under the parties cross-license agreement relating to the manufacture of ALN-VSP clinical trial material for use in China. The Arbutus arbitration hearing was held in May 2015 and we now expect a decision from the arbitration panel during the first quarter of 2016. We have not recorded the expense of $5.0 million for this milestone because we do not believe it has been achieved. Our policy is to expense these potential milestones when incurred and record them as research and development expense. Indemnifications Licensor indemnification — In connection with our license agreements with Max Planck relating to the Tuschl I and Tuschl II patent applications, we are required to indemnify Max Planck for certain damages arising in connection with the intellectual property rights licensed under the agreements. Under the Max Planck indemnification agreement, we are responsible for paying the costs of any litigation relating to the license agreements or the underlying intellectual property rights, including the costs associated with certain litigation regarding the Tuschl patents, which was settled during 2011, as well as certain costs associated with defending the University of Utah litigation described above. In connection with the settlement of the litigation regarding the Tuschl patents, we also agreed to indemnify Whitehead, MIT and UMass for certain costs associated with defending the University of Utah litigation. In connection with our research agreement with Acuitas, we agreed to indemnify Acuitas for certain legal costs, subject to certain exceptions and limitations, associated with the Arbutus litigation described above. These indemnification costs were charged to general and administrative expense. We are also a party to a number of agreements entered into in the ordinary course of business, which contain typical provisions that obligate us to indemnify the other parties to such agreements upon the occurrence of certain events. Such indemnification obligations are usually in effect from the date of execution of the applicable agreement for a period equal to the applicable statute of limitations. Our maximum potential future liability under any such indemnification provisions is uncertain. However, to date, other than certain costs associated with certain previously settled litigation related to the Tuschl patents and the Arbutus litigation described above, and certain defense costs related to the University of Utah litigation also described above, we have not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. We have determined that the estimated aggregate fair value of our potential liabilities under all such indemnification provisions is minimal and have not recorded any liability related to such indemnification provisions at December 31, 2015 or 2014. |

STOCK INCENTIVE PLANS | 9. STOCK INCENTIVE PLANS Stock Plans In June 2009, our stockholders approved an amendment and restatement of our 2004 Stock Incentive Plan, or the Amended and Restated 2004 Plan, which replaced our 2004 Stock Incentive Plan, as amended, or the 2004 Plan. At December 31, 2015, the Amended and Restated 2004 Plan provided for the granting of stock options to purchase up to 12,366,485 shares of common stock. Prior to the adoption of the Amended and Restated 2004 Plan, we were authorized to grant both stock options and restricted stock awards under the 2004 Plan. As of the effective date of the Amended and Restated 2004 Plan, we may only grant stock options under the Amended and Restated 2004 Plan, provided that the terms and conditions of any restricted stock awards outstanding under the 2004 Plan will continue to be governed by the Amended and Restated 2004 Plan. In June 2009, our stockholders also approved our 2009 Stock Incentive Plan. In May 2015, our stockholders approved an amendment and restatement of the 2009 Stock Incentive Plan, or the Amended and Restated 2009 Plan, which increased the number of shares of common stock authorized for issuance from 5,900,000 to 11,700,000. The Amended and Restated 2009 Plan provides for the granting of stock options, restricted stock awards and units, stock appreciation rights and other stock-based awards. The Amended and Restated 2009 Plan has a fungible share pool. Any award that is not a full value award is counted against the authorized share limits specified in the Amended and Restated 2009 Plan as one share for each share of common stock subject to the award, and all full value awards, defined in the Amended and Restated 2009 Plan as restricted stock awards or other stock-based awards, are counted as one and a half shares for each one share of common stock subject to such full value award. At December 31, 2015, an aggregate of 13,626,583 shares of common stock were reserved for issuance under our stock plans, including outstanding stock options to purchase 9,959,512 shares of common stock, 3,482,679 of common stock available for additional equity awards and 184,392 shares available for future grant under our 2004 Employee Stock Purchase Plan, or the 2004 ESPP. Each stock option shall expire within ten years of issuance. Time vested stock options granted by us to employees generally vest as to 25% of the shares on the first anniversary of the grant date and 6.25% of the shares at the end of each successive three-month period until fully vested. Performance-based stock options granted to employees in 2015 vest as to one-fourth of the shares upon the achievement of each of four specific clinical development or commercial events, as approved by our compensation committee. Performance-based stock options granted to employees in 2013 and 2014 each vest as to one-third of the shares upon the achievement of each of three specific clinical development or regulatory events, as approved by our compensation committee. Stock-Based Compensation The following table summarizes stock-based compensation expense by type of award during the three years ended December 31, 2015, in thousands: 2015 2014 2013 Stock-based compensation expense by type of award: Stock options $ 43,078 $ 24,603 $ 13,839 Performance-based stock options — 4,960 — Restricted stock awards 555 1,068 3,420 ESPP share issuances 694 392 261 Non-employee stock options 1,456 2,038 3,183 $ 45,783 $ 33,061 $ 20,703 The following table summarizes our unrecognized stock-based compensation expense, net of estimated forfeitures, at December 31, 2015 by type of awards and the weighted-average period over which that expense is expected to be recognized: At December 31, 2015 Unrecognized Expense, Net of Estimated Forfeitures Weighted-average Recognition Period (in thousands) (in years) Type of award: Time-based stock options $ 128,073 2.87 Performance-based stock options 62,000 * Restricted stock awards 1,108 2.54 ESPP share issuances 350 0.33 * Performance-based stock options are recorded as expense when vesting events are determined to be probable. Valuation Assumptions for Stock Options The fair value of stock options, at date of grant, based on the following assumptions, was estimated using the Black-Scholes option-pricing model. Our expected stock-price volatility assumption is based on the historical volatility of our publicly traded stock. The expected life assumption is based on our historical data. The dividend yield assumption is based on the fact that we have never paid cash dividends and have no present intention to pay cash dividends. The risk-free interest rate used for each grant is equal to the zero coupon rate for instruments with a similar expected life. 2015 2014 2013 Risk-free interest rate 1.0-2.0 % 1.7-2.3 % 1.0-2.0 % Expected dividend yield — — — Expected option life 3.5-7.5 years 5.5-7.5 years 5.6 years Expected volatility 53-60 % 53-57 % 55-56 % Stock Option Activity The following table summarizes the activity of our stock option plans, excluding performance-based stock options: Number of Options (in thousands) Weighted- Exercise Price Weighted- average Remaining Contractual Term (in Aggregate Intrinsic Value (in thousands) Outstanding, December 31, 2014 7,530 $ 33.46 Granted 2,403 99.20 Exercised (1,438 ) 19.64 Cancelled (177 ) 70.67 Outstanding, December 31, 2015 8,318 $ 54.05 6.85 $ 352,646 Exercisable at December 31, 2015 4,699 $ 30.61 5.31 $ 299,365 Vested or expected to vest at December 31, 2015 8,048 $ 52.89 6.78 $ 349,933 The weighted-average fair value of stock options granted was $51.28, $39.08 and $26.33 per share for the years ended December 31, 2015, 2014 and 2013, respectively. The intrinsic value of stock options exercised was $130.0 million, $126.5 million and $57.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. We satisfy stock option exercises with newly issued shares of our common stock. Performance-Based Stock Options We grant performance-based stock options to employees that vest as to one-fourth of the shares upon the achievement of each of four specific clinical development or commercial events, as approved by our compensation committee, for 2015 grants, and that vest as to one-third of the shares upon the achievement of each of three specific clinical development or regulatory events, as approved by our compensation committee, for 2013 and 2014 grants. The following table summarizes the activity of our performance-based stock options: Number of Options (in thousands) Weighted- Exercise Price Weighted- average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding, December 31, 2014 639 $ 73.15 Granted 1,072 91.07 Exercised (29 ) 63.00 Cancelled (40 ) 77.64 Outstanding, December 31, 2015 1,642 $ 84.92 9.15 $ 16,244 Exercisable at December 31, 2015 120 $ 63.00 7.84 $ 3,741 On December 12, 2014, we achieved the first performance criteria of the December 18, 2013 grant of performance-based stock options and each stock option award granted was vested as to one-third of the performance-based portion of the award. The weighted-average grant date fair value of the first tranche of the December 18, 2013 performance-based stock option awards was $32.26 per share. During the fourth quarter of 2014, we determined the first performance criteria of the December 18, 2013 grant was probable and began to record expense, which was recognized in full as of December 12, 2014. The intrinsic value of performance-based stock options exercised was $1.4 million and $0.1 million for the years ended December 31, 2015 and 2014, respectively. We satisfy performance-based stock option exercises with newly issued shares of our common stock. As of the grant date and December 31, 2015, we had determined that the remaining performance criteria of all outstanding performance-based stock options reflected in the table above were not probable. As a result, we had not recorded stock-based compensation expense for these performance-based stock options as of December 31, 2015. On February 1, 2016, we achieved the first performance criteria of the December 17, 2014 grant of performance-based stock options upon the completion of patient enrollment in our Phase 3 APOLLO study and the stock option was vested as to one-third of the performance-based portion of the grant. As a result, in the first quarter of 2016, we expect to record stock-based compensation expense of approximately $8.0 million related to these 159,122 vested options. Contingent Stock Option Awards On December 17, 2014, the compensation committee of our board of directors approved the grant of stock options to purchase 612,085 shares of our common stock, at an exercise price of $96.45 per share, to members of our management team. These stock option grants were approved subject to and contingent upon approval by our stockholders at our 2015 annual meeting of the Amended and Restated 2009 Plan, to, among other things, increase the shares authorized for issuance thereunder, which approval was obtained in May 2015. One-half of the contingent stock options granted are time-based stock options and one-half are performance-based stock options. The grant-date fair value of the contingent stock options is based on a Black-Scholes valuation model based on the fair market value of the stock May 1, 2015, the date of such stockholder approval. We began recording stock-based compensation expense relating to this contingent stock option grant on May 1, 2015. Restricted Stock Awards In October 2010, we granted 113,370 shares of our restricted stock to certain employees. These restricted stock awards were valued at $1.4 million on the grant date. These restricted stock awards vested ratably over an approximate three-year period. In May 2011, we granted an aggregate of 229,806 shares of performance-based restricted stock awards to our employees, excluding our leadership team. These restricted stock awards were valued at $2.3 million on the grant date and had a contractual term of five years. The vesting of these awards was predicated on our achievement of certain clinical development goals. These awards have vested in full due to the achievement of these goals in 2011 and 2013. In January 2012, as part of our post-restructuring retention program, we granted an aggregate of 508,928 shares of restricted stock to our retained employees, excluding our chief executive officer and president and chief operating officer. These restricted stock awards were valued at $5.3 million on the grant date and vested in full on the second anniversary of the grant date. The total fair value of restricted stock awards that vested during the years ended December 31, 2015, 2014 and 2013 (measured on the date of vesting) was $1.2 million, $44.4 million and $5.8 million, respectively. At December 31, 2015 and 2014, there were 19,271 and 30,149 unvested restricted stock awards, including restricted stock and restricted stock units, respectively. The weighted-average grant date fair value of these unvested restricted stock awards was approximately $70. Employee Stock Purchase Plan In 2004, we adopted the 2004 ESPP with 315,789 shares authorized for issuance. In June 2010, our stockholders approved an amendment to the 2004 ESPP, which increased the shares authorized for issuance from 315,789 shares to 715,789 shares. Under the 2004 ESPP, each offering period is six months, at the end of which employees may purchase shares of common stock through payroll deductions made over the term of the offering. The per-share purchase price at the end of each offering period is equal to the lesser of 85% of the closing price of our common stock at the beginning or end of the offering period. We issued 22,639, 21,938 and 45,141 shares during the years ended December 31, 2015, 2014 and 2013, respectively, and at December 31, 2015, 184,392 shares were available for issuance under the 2004 ESPP. The weighted-average fair value of stock purchase rights granted as part of the 2004 ESPP was $29.96, $17.03 and $11.49 per share for the years ended December 31, 2015, 2014 and 2013, respectively. The fair value was estimated using the Black-Scholes option-pricing model. During the three years ended December 31, 2015, we used a weighted-average stock-price volatility of approximately 55%, expected option life assumption of six months and a risk-free interest rate of 0.1%. |

INCOME TAXES | 10. INCOME TAXES The domestic and foreign components of loss before income taxes are as follows, in thousands: 2015 2014 2013 Domestic $ (245,681 ) $ (372,137 ) $ (81,109 ) Foreign (44,392 ) (28,467 ) (10,811 ) Loss before income taxes $ (290,073 ) $ (400,604 ) $ (91,920 ) Deferred income taxes reflect the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes. We establish a valuation allowance when uncertainty exists as to whether all or a portion of the net deferred tax assets will be realized. As of December 31, 2015, we elected to early adopt new guidance issued by the FASB in November 2015, which simplifies the presentation of deferred income taxes by eliminating the need for entities to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. We adopted this guidance prospectively and, as a result, prior consolidated balance sheets were not retrospectively adjusted. As of December 31, 2014, we allocated the valuation allowance between current and noncurrent deferred tax assets and liabilities. As a result of this allocation, we had recorded a long-term deferred tax asset of $31.7 million and a corresponding short-term deferred tax liability of $31.7 million on the balance sheet. Components of the net deferred tax (liability) asset at December 31, 2015 and 2014 are as follows, in thousands: 2015 2014 Deferred tax assets: Net operating loss carryforwards $ 253,908 $ 176,789 Research and development credits 61,424 38,204 AMT credits 788 788 Foreign tax credits 3,196 3,196 Capitalized research and development and start-up costs 19,075 19,246 Deferred revenue 17,279 14,273 Deferred compensation 33,397 24,516 Intangible assets 16,181 17,637 Partnership interest 689 689 Other 6,508 5,871 Total deferred tax assets 412,445 301,209 Deferred tax liabilities: Unrealized gain on available-for-sale securities (14,947 ) (32,793 ) Deferred tax asset valuation allowance (397,498 ) (268,416 ) Net deferred tax liability $ — $ — The benefit from income taxes for the years ended December 31, 2015, 2014 and 2013 is as follows, in thousands: 2015 2014 2013 U.S.: Current $ — $ — $ 34 Deferred — (40,209 ) (2,695 ) Total U.S. — (40,209 ) (2,661 ) Foreign: Current — — — Deferred — — (34 ) Total Foreign — — (34 ) Benefit from income taxes $ — $ (40,209 ) $ (2,695 ) Our effective income tax rate differs from the statutory federal income tax rate as follows for the years ended December 31, 2015, 2014 and 2013: 2015 2014 2013 At U.S. federal statutory rate 35.0 % 35.0 % 35.0 % State taxes, net of federal effect 4.0 1.8 4.3 Stock-based compensation (1.1 ) (0.2 ) 0.8 Tax credits 8.0 3.5 8.5 Orphan drug credit (2.0 ) (0.6 ) (2.7 ) Other permanent items (0.1 ) — (0.3 ) Foreign rate differential (5.4 ) (2.5 ) (4.1 ) In-process research and development — (19.4 ) — Tax basis in intangible assets as a result of Sirna transaction — 4.2 — Valuation allowance (38.4 ) (11.8 ) (38.5 ) Effective income tax rate — % 10.0 % 3.0 % We have evaluated the positive and negative evidence bearing upon the realizability of our deferred tax assets. We have concluded, in accordance with the applicable accounting standards, that it is more likely than not that we may not realize the benefit of all of our deferred tax assets. Accordingly, we have recorded a valuation allowance against the deferred tax assets that management believes will not be realized. We reevaluate the positive and negative evidence on a quarterly basis. The valuation allowance increased by $129.1 million, $46.0 million and $29.7 million for the years ended December 31, 2015, 2014 and 2013, respectively, due primarily to additional operating losses and research and development credits. In 2014, increases to the valuation allowance were partially offset by decreases related to the recognition of deferred revenue. For the years ended December 31, 2015, 2014 and 2013, we recorded a tax benefit of zero, $40.2 million and $2.7 million, respectively. For the years ended December 31, 2014 and 2013, we recorded unrealized gains on our investments in available-for-sale securities in other comprehensive income and additional paid-in capital. We recorded a benefit of $19.5 million and $2.7 million for the years ended December 31, 2014 and 2013, respectively, due to the recognition of corresponding income tax expense associated with the increase in the value of our investment in Regulus that we carried at fair market value during the same period. In addition, for the year ended December 31, 2014, we recorded a benefit of $20.7 million due to the difference between the fair value of stock and the cash proceeds received from Sanofi Genzyme for the issuance of our common stock calculated at the closing date of the transaction. The corresponding income tax expense has been recorded in other comprehensive income and additional paid-in capital, respectively. Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income and additional paid-in capital. In periods in which we have a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as other comprehensive income and additional paid-in capital, we must allocate the tax provision to the other categories of earnings. We then record a related tax benefit in continuing operations. The deferred tax assets above exclude $123.6 million of net operating losses and $0.4 million of federal and state research and development credits related to tax deductions from the exercise of stock options subsequent to the adoption of the 2006 accounting standard on stock-based compensation. This amount represents excess tax benefits and has not been included in the gross deferred tax assets since, if subsequently recognized, these tax benefits would be credited directly to contributed capital. At December 31, 2015, we had federal and state net operating loss carryforwards of $931.2 million and $991.5 million, respectively. These amounts will reduce future taxable income that will expire at various dates through 2035. At December 31, 2015, federal and state research and development credit carryforwards were $53.2 million and $13.3 million, respectively, available to reduce future tax liabilities that expire at various dates through 2035. At December 31, 2015, foreign tax credit carryforwards were $3.2 million available to reduce future tax liabilities that expire in 2017. At December 31, 2015, alternative minimum tax credits of $0.8 million are available to reduce future regular tax liabilities to the extent such regular tax less other non-refundable credits exceeds the tentative minimum tax. Ownership changes, as defined in the Internal Revenue Code, including those resulting from the issuance of common stock in connection with our public offerings, may limit the amount of net operating loss that can be utilized to offset future taxable income or tax liability. At December 31, 2015, 2014 and 2013, we had no unrecognized tax benefits that, if recognized, would favorably impact our effective income tax rate in future periods. The tax years 2010 through 2015 remain open to examination by major taxing jurisdictions to which we are subject, which are primarily in the United States, as carryforward attributes generated in years past may still be adjusted upon examination by the Internal Revenue Service or state tax authorities if they have or will be used in a future period. We have not recorded any interest and penalties on any unrecognized tax benefits since its inception. |

Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements reflect the operations of Alnylam and our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make estimates and assumptions that affect the reported amounts 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 reporting period. Actual results could differ from those estimates. |
Concentrations of Credit Risk and Significant Customers | Concentrations of Credit Risk and Significant Customers Financial instruments that potentially expose us to concentrations of credit risk consist primarily of cash, cash equivalents and fixed income marketable securities. At December 31, 2015 and 2014, substantially all of our cash, cash equivalents and fixed income marketable securities were invested in money market funds, certificates of deposit, commercial paper, corporate notes, municipal debt securities, U.S. government-sponsored enterprise securities and U.S. treasury securities through highly rated financial institutions. Corporate notes also include foreign bonds denominated in U.S. dollars. Investments are restricted, in accordance with our investment policy, to a concentration limit per issuer. In recent periods, our revenues from collaborations have been generated primarily from Sanofi Genzyme, the specialty care global business unit of Sanofi, or Sanofi Genzyme, Takeda Pharmaceutical Company Limited, or Takeda, Monsanto Company, or Monsanto, The Medicines Company, or MDCO, and Cubist Pharmaceuticals, Inc., or Cubist (now a wholly-owned subsidiary of Merck & Co., Inc.). For the year ended December 31, 2015, our billed and unbilled collaboration receivables were composed primarily of amounts of expense reimbursement due from Sanofi Genzyme and certain milestones due from Ionis Pharmaceuticals, Inc., or Ionis (formerly Isis Pharmaceuticals, Inc.). For the year ended December 31, 2014, our billed and unbilled collaboration receivables were composed primarily of amounts due from Sanofi Genzyme and MDCO based upon the achievement of certain milestones and also, with respect to MDCO, expense reimbursement. The following table summarizes customers that represent greater than 10% of our net revenues from collaborators, for the periods indicated: Year Ended December 31, 2015 2014 2013 Sanofi Genzyme 27 % * * MDCO 25 % 21 % * Takeda 22 % 43 % 47 % Monsanto 14 % 30 % 12 % Cubist * * 21 % The following table summarizes customers with amounts due that represent greater than 10% of our billed and unbilled collaboration receivables balance, at the periods indicated: At December 31, 2015 2014 Sanofi Genzyme 88 % 63 % Ionis 12 % * MDCO * 37 % * Represents 10% or less |
Fair Value Measurements | Fair Value Measurements The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices (adjusted), interest rates and yield curves. Fair values determined by Level 3 inputs utilize unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. The fair value hierarchy level is determined by the lowest level of significant input. |
Investments in Marketable Securities | Investments in Marketable Securities We invest our excess cash balances in short-term and long-term marketable debt and equity securities. We classify our investments in marketable debt securities as either held-to-maturity or available-for-sale based on facts and circumstances present at the time we purchased the securities. At each balance sheet date presented, we classified all of our investments in debt and equity securities as available-for-sale. We report available-for-sale investments at fair value at each balance sheet date and include any unrealized holding gains and losses (the adjustment to fair value) in accumulated other comprehensive income (loss), a component of stockholders’ equity. At December 31, 2015, the balance in our accumulated other comprehensive income was composed solely of activity related to our available-for-sale marketable securities, including our investment in equity securities of Regulus Therapeutics Inc., or Regulus. Realized gains and losses are determined using the specific identification method and are included in other income (expense). We did not recognize any realized gains or losses from sales of our available-for-sale securities during the year ended December 31, 2015 and, as a result, did not reclassify any amount out of accumulated other comprehensive income (loss) for the same period. If any adjustment to fair value reflects a decline in the value of the investment, we consider all available evidence to evaluate the extent to which the decline is “other than temporary,” including our intention to sell and, if so, mark the investment to market through a charge to our consolidated statements of comprehensive income (loss). We did not record any impairment charges related to our fixed income marketable securities during the years ended December 31, 2015, 2014 or 2013. Our marketable securities are classified as cash equivalents if the original maturity, from the date of purchase, is 90 days or less, and as marketable securities if the original maturity, from the date of purchase, is in excess of 90 days. Our cash equivalents are composed of commercial paper, corporate notes, U.S. government-sponsored enterprise securities and money market funds. We account for our investment in Regulus as an available-for-sale marketable security. Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of earnings, such as other comprehensive income. In periods in which we have a year-to-date pre-tax loss from continuing operations and pre-tax income in other categories of earnings, such as other comprehensive income, we must allocate the tax provision to the other categories of earnings. We then record a related tax benefit in continuing operations. Upon sales of our available-for-sale marketable securities, we apply the aggregate portfolio approach to recognize the related tax provision or benefit into income (loss) from continuing operations. As a result, the disproportionate tax effect remains in accumulated other comprehensive income (loss) as long as we maintain an investment portfolio. |
Estimated Liability for Development Costs | Estimated Liability for Development Costs We record accrued liabilities related to expenses for which service providers have not yet billed us with respect to products we have received or services that we have incurred, specifically related to ongoing pre-clinical studies and clinical trials. These costs primarily relate to third-party clinical management costs, laboratory and analysis costs, toxicology studies and investigator fees. We have multiple product candidates in concurrent pre-clinical studies and clinical trials at multiple clinical sites throughout the world. In order to ensure that we have adequately provided for ongoing pre-clinical and clinical development costs during the period in which we incur such costs, we maintain an accrual to cover these expenses. We update the estimate for this accrual on at least a quarterly basis. The assessment of these costs is a subjective process that requires judgment. Upon settlement, these costs may differ materially from the amounts accrued in our consolidated financial statements. Our historical accrual estimates have not been materially different from our actual costs. |
Revenue Recognition | Revenue Recognition We have entered into collaboration agreements with leading pharmaceutical and life sciences companies, including Novartis Pharma AG and one of its affiliates (which assigned its rights and obligations to Arrowhead Research Corporation, or Arrowhead, in early 2015), F. Hoffmann-La Roche Ltd (which assigned its rights and obligations to Arrowhead in 2011), Takeda, Kyowa Hakko Kirin Co., Ltd., or Kyowa Hakko Kirin, Cubist, Monsanto, Sanofi Genzyme and MDCO. The terms of our collaboration agreements typically include deliverables such as non-refundable license fees, funding of research and development, payments based upon achievement of clinical and pre-clinical development milestones, regulatory milestones, manufacturing services, sales milestones and royalties on product sales. These agreements are generally referred to as multiple element arrangements. We apply the accounting standard on revenue recognition for multiple element arrangements. The fair value of deliverables under the arrangement may be derived using a “best estimate of selling price” if vendor specific objective evidence and third-party evidence is not available. Deliverables under the arrangement will be separate units of accounting provided that (i) a delivered item has value to the customer on a standalone basis and (ii) if the arrangement includes a general right of return relative to the delivered item, delivery or performance of the undelivered item is considered probable and substantially in the control of the vendor. We recognize upfront license payments as revenue upon delivery of the license only if the license has standalone value of the undelivered performance obligations, typically including research and/or steering committee services, can be determined. If the fair value of the undelivered performance obligations can be determined, such obligations would then be accounted for separately as performed. If the license is considered to not have standalone value, the arrangement would then be accounted for as a single unit of accounting and the license payments and payments for performance obligations are recognized as revenue over the estimated period of when the performance obligations are performed or deferred indefinitely until the undelivered performance obligation can be determined. As a biotechnology entity with unique and specialized delivered and undelivered performance obligations, we have been unable to demonstrate standalone value in our multiple element arrangements. Whenever we determine that an arrangement should be accounted for as a single unit of accounting, we determine the period over which the performance obligations will be performed and revenue will be recognized. Revenue is recognized using either a proportional performance or straight-line method. We recognize revenue using the proportional performance method when the level of effort required to complete our performance obligations under an arrangement can be reasonably estimated and such performance obligations are provided on a best-efforts basis. Direct labor hours or full-time equivalents are typically used as the measure of performance. The amount of revenue recognized under the proportional performance method is determined by multiplying the total payments under the contract, excluding royalties and payments contingent upon achievement of milestones, by the ratio of level of effort incurred to date to estimated total level of effort required to complete our performance obligations under the arrangement. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the proportional performance method, as of the period ending date. If we cannot reasonably estimate the level of effort to complete our performance obligations under an arrangement, we recognize revenue under the arrangement on a straight-line basis over the period we are expected to complete our performance obligations. Revenue is limited to the lesser of the cumulative amount of payments received or the cumulative amount of revenue earned, as determined using the straight-line method, as of the period ending date. Significant management judgment is required in determining the level of effort required under an arrangement and the period over which we are expected to complete our performance obligations under an arrangement. Steering committee services that are not inconsequential or perfunctory and that are determined to be performance obligations are combined with other research services or performance obligations required under an arrangement, if any, in determining the level of effort required in an arrangement and the period over which we expect to complete our aggregate performance obligations. Many of our collaboration agreements entitle us to additional payments upon the achievement of performance-based milestones. These milestones are generally categorized into three types; development milestones which are generally based on the advancement of our pipeline and initiation of clinical trials, regulatory milestones which are generally based on the submission, filing or approval of regulatory applications such as a new drug application in the United States, and commercialization milestones which are generally based on meeting specific thresholds of sales in certain geographic areas. If the achievement of a milestone is considered probable at the inception of the collaboration, the related milestone payment is included with other collaboration consideration, such as upfront fees and research funding, in our revenue model. Milestones that are tied to regulatory approval are not considered probable of being achieved until such approval is received. Milestones tied to counter-party performance are not included in our revenue model until the performance conditions are met. Upfront and ongoing development milestones are not subject to refund if the development activities are not successful. We perform an assessment to determine whether a substantive milestone exists at the inception of our collaborative arrangements. In evaluating if a milestone is substantive, we consider whether uncertainty exists as to the achievement of the milestone event at the inception of the arrangement, the achievement of the milestone involves substantive effort and can only be achieved based in whole or part on the performance or the occurrence of a specific outcome resulting from our performance, the amount of the milestone payment appears reasonable either in relation to the effort expected to be expended or to the projected enhancement of the value of the delivered items, there is any future performance required to earn the milestone, and the consideration is reasonable relative to all deliverables and payment terms in the arrangement. When a substantive milestone is achieved, the accounting rules permit us to recognize revenue related to the milestone payment in its entirety. To date, we have not recorded any substantive milestones under our collaborations because we have not identified any milestones that meet the required criteria listed above. We have deferred recognition of payments for achievement of non-substantive milestones and recognized revenue over the estimated period of performance applicable to each collaborative arrangement. As these milestones are achieved, we will recognize as revenue a portion of the milestone payment, which is equal to the percentage of the performance period completed when the milestone is achieved, multiplied by the amount of the milestone payment, upon achievement of such milestone. We will recognize the remaining portion of the milestone payment over the remaining performance period under the proportional performance method or on a straight-line basis. For revenue generating arrangements where we, as a vendor, provide consideration to a licensor or collaborator, as a customer, we apply the accounting standard that governs such transactions. This standard addresses the accounting for revenue arrangements where both the vendor and the customer make cash payments to each other for services and/or products. A payment to a customer is presumed to be a reduction of the selling price unless we receive an identifiable benefit for the payment and it can reasonably estimate the fair value of the benefit received. Payments to a customer that are deemed a reduction of selling price are recorded first as a reduction of revenue, to the extent of both cumulative revenue recorded to date and probable future revenues, which include any unamortized deferred revenue balances, under all arrangements with such customer, and then as an expense. Payments that are not deemed to be a reduction of selling price are recorded as an expense. We evaluate our collaborative agreements for proper classification in our consolidated statements of comprehensive loss based on the nature of the underlying activity. Transactions between collaborators recorded in our consolidated statements of comprehensive loss are recorded on either a gross or net basis, depending on the characteristics of the collaborative relationship. We generally reflect amounts due under our collaborative agreements related to cost-sharing of development activities as revenue. Amounts received prior to satisfying the above revenue recognition criteria are recorded as deferred revenue in the accompanying consolidated balance sheets. Although we follow detailed guidelines in measuring revenue, certain judgments affect the application of our revenue policy. For example, in connection with our existing collaboration agreements, we have recorded on our consolidated balance sheet short-term and long-term deferred revenue based on our best estimate of when such revenue will be recognized. Short-term deferred revenue consists of amounts that are expected to be recognized as revenue in the next 12 months. Amounts that we expect will not be recognized within the next 12 months are classified as long-term deferred revenue. However, this estimate is based on our current operating plan and, if our operating plan should change in the future, we may recognize a different amount of deferred revenue over the next 12-month period. The estimate of deferred revenue also reflects management’s estimate of the periods of our involvement in certain of our collaborations. Our performance obligations under these collaborations consist of participation on steering committees and the performance of other research and development services. In certain instances, the timing of satisfying these obligations can be difficult to estimate. Accordingly, our estimates may change in the future. Such changes to estimates would result in a change in revenue recognition amounts. If these estimates and judgments change over the course of these agreements, it may affect the timing and amount of revenue that we recognize and record in future periods. At December 31, 2015, we had short-term and long-term deferred revenue of $15.4 million and $53.0 million, respectively, related to our collaborations. |
Income Taxes | Income Taxes We use the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities reflect the impact of temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured under enacted tax laws. A valuation allowance is required to offset any net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax asset will not be realized. We account for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. Our policy is to accrue interest and penalties related to unrecognized tax positions in income tax expense. As of December 31, 2015, we have not recorded significant interest and penalty expense related to uncertain tax positions. |
Research and Development Costs | Research and Development Costs We expense research and development costs as incurred. Included in research and development costs are wages, benefits and other operating costs, facilities, supplies, external services, clinical trial and manufacturing costs, and overhead directly related to our research and development operations, as well as costs to acquire technology licenses. We have entered into several license agreements for rights to utilize certain technologies. The terms of the licenses may provide for upfront payments, annual maintenance payments, milestone payments based upon certain specified events being achieved and royalties on product sales. We charge costs to acquire and maintain licensed technology that has not reached technological feasibility and does not have alternative future use to research and development expense as incurred. During the years ended December 31, 2015, 2014 and 2013, we charged to research and development expense costs associated with license fees of $3.5 million, $12.1 million and $8.0 million, respectively. |
Accounting for Stock-Based Compensation | Accounting for Stock-Based Compensation We have stock incentive plans and an employee stock purchase plan under which we grant equity instruments. We account for all stock-based awards granted to employees at their fair value and generally recognize compensation expense over the vesting period of the award. Determining the amount of stock-based compensation to be recorded requires us to develop estimates of fair values of stock options as of the grant date. We calculate the grant date fair values using the Black-Scholes valuation model. Our expected stock price volatility assumption is based on the historical volatility of our publicly traded stock. For stock-based awards granted to non-employees, we generally recognize compensation expense over the vesting period of the award, which is generally the period during which services are rendered by such non-employees. At the end of each financial reporting period prior to vesting, we re-measure the value of these stock-based awards (as calculated using the Black-Scholes option-pricing model) using the then-current fair value of our common stock. Stock options granted by us to non-employees, other than members of our board of directors and scientific advisory board members, generally vest over the service period. The fair value of restricted stock awards granted to employees is based upon the quoted closing market price per share on the date of grant, adjusted for assumed forfeitures. Expense is recognized over the vesting period, commencing when we determine that it is probable that the awards will vest. For performance-based stock awards, expense is first recorded when we determine that the achievement of such performance conditions is deemed probable. This determination requires significant judgment by management. At the probable date, we record a cumulative expense catch-up, with remaining expense amortized over the remaining service period. |
Comprehensive Loss | Comprehensive Loss Comprehensive loss is comprised of net loss and certain changes in stockholders’ equity that are excluded from net loss. We include foreign currency translation adjustments in other comprehensive loss as the functional currency is not the United States dollar. We include unrealized gains and losses on certain marketable securities in other comprehensive loss. |
Net Loss Per Common Share | Net Loss Per Common Share We compute basic net loss per common share by dividing net loss by the weighted-average number of common shares outstanding. We compute diluted net loss per common share by dividing net loss by the weighted-average number of common shares and dilutive potential common share equivalents then outstanding. Potential common shares consist of shares issuable upon the exercise of stock options (using the treasury stock method), and unvested restricted stock awards. Because the inclusion of potential common shares would be anti-dilutive for all periods presented, diluted net loss per common share is the same as basic net loss per common share. The following table sets forth for the periods presented the potential common shares (prior to consideration of the treasury stock method) excluded from the calculation of net loss per common share because their inclusion would be anti-dilutive, in thousands: At December 31, 2015 2014 2013 Options to purchase common stock 9,960 8,169 8,713 Unvested restricted common stock 19 30 500 9,979 8,199 9,213 |
Segment Information | Segment Information We operate in a single reporting segment, the discovery, development and commercialization of RNAi therapeutics. |
Subsequent Events | Subsequent Events We did not have any material recognized subsequent events. However, we did have the following nonrecognized subsequent event, which is more fully described in Note 7: • On February 10, 2016, we entered into an agreement to purchase land in Norton, Massachusetts for the construction of a manufacturing facility. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued a new revenue recognition standard which amends revenue recognition principles and provides a single, comprehensive set of criteria for revenue recognition within and across all industries. The new standard provides a five step framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures pertaining to revenue recognition in both interim and annual periods. In August 2015, the FASB deferred the effective date of the new revenue standard from January 1, 2017 to January 1, 2018. Early adoption is permitted any time after the original effective date, which for us is January 1, 2017. The standard allows for adoption using a full retrospective method or a modified retrospective method. We are currently evaluating the timing, method of adoption and the expected impact that the standard could have on our consolidated financial statements and related disclosures. In April 2015, the FASB amended its guidance on internal use software to clarify the accounting by customers for fees paid in a cloud computing arrangement. Under this guidance, if a cloud computing arrangement includes a software license, the software license element of the arrangement should be accounted for consistent with the customer’s accounting for other software licenses. If a cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. The new guidance became effective for us on January 1, 2016. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements and related disclosures. In November 2015, the FASB issued final guidance that requires companies to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. This guidance allows for adoption on either a prospective or retrospective basis. This guidance will be effective on January 1, 2017. Early adoption is permitted. We have elected to early adopt this guidance on a prospective basis and, as a result, prior consolidated balance sheets were not retrospectively adjusted. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In January 2016, the FASB issued new guidance on recognition and measurement of financial assets and financial liabilities. The new guidance will impact the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. All equity investments in unconsolidated entities (other than those accounted for under the equity method of accounting) will generally be measured at fair value with changes in fair value recognized through earnings. There will no longer be an available-for-sale classification (changes in fair value reported in other comprehensive income (loss)) for equity securities with readily determinable fair values. In addition, the FASB clarified the need for a valuation allowance on deferred tax assets resulting from unrealized losses on available-for-sale debt securities. In general, the new guidance will require modified retrospective application to all outstanding instruments, with a cumulative effect adjustment recorded to opening retained earnings. This guidance will be effective for us on January 1, 2018. We are currently evaluating the expected impact that the standard could have on our consolidated financial statements and related disclosures. |
