EXPLANATORY NOTE

We are filing this Amendment No. 1 to our Quarterly Report on Form 10-Q/A (the “Amended Report”), which was originally filed with the Securities and Exchange Commission on Form 10-Q on May 11, 2015 (the “Original Report” or “Quarterly Report on Form 10-Q”), to reflect a restatement of our financial statements.

As discussed in Note 13 to our financial statements, subsequent to the issuance of the Original Report, we and the Audit Committee of our Board of Directors concluded that we should restate our balance sheets as of December 31, 2014 and March 31, 2015, and our statements of operations, comprehensive income (loss), and cash flows for the three months ended March 31, 2015 to correct the following errors:

·                  In the second quarter of 2014, we recorded an income tax benefit by reducing a portion of our valuation allowance against our gross deferred tax assets.  In determining the amount of the valuation allowance release, we considered anticipated 2015 tax losses which would generate a refund of a portion of federal income taxes paid in 2014.  We have now determined that, as a matter of accounting principle, the net deferred tax asset recorded on our balance sheets was overstated as of December 31, 2014 and March 31, 2015 and the income tax provision on our statement of operations was understated for the three months ended March 31, 2015. Our cash position and operating expenses were not affected.

For the reasons discussed above, we are filing this Amended Report in order to amend our financial statements and the following items in Part I of the Original Report to the extent necessary to correct the errors discussed above and make corresponding revisions to our financial information cited elsewhere in this Amended Report:

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

·                  Item 4. Controls and Procedures

In addition, in accordance with applicable Securities and Exchange Commission rules, this Amended Report includes updated certifications from our chief executive officer and chief financial officer as Exhibits 31.3, 31.4, 32.3 and 32.4.  Other than minor conforming revisions made to the financial information contained in Part II Item 1A. Risk Factors, none of the remaining Items of our Original Report are amended hereby. Items that have not been amended have been omitted herefrom.

In order to preserve the nature and character of the disclosures set forth in the Original Report, except as expressly noted above, this Amended Report speaks as of the date of the filing of the Original Report, May 11, 2015, and we have not updated the disclosures in the Amended Report to speak as of a later date.  All information contained in this Amended Report is subject to updating and supplementing as provided in our reports filed with the Securities and Exchange Commission subsequent to the date of the Original Report.

Description of Business and Organization

Ophthotech Corporation (the “Company” or “Ophthotech”) was incorporated on January 5, 2007, in Delaware. The Company is a biopharmaceutical company specializing in the development of novel therapeutics to treat diseases of the back of the eye, with a focus on developing therapeutics for age-related macular degeneration, or AMD. The Company’s most advanced product candidate is Fovista, which is in Phase 3 clinical development for use in combination with anti-VEGF therapy that represent the current standard of care for the treatment of wet AMD. The Company has completed one Phase 1 and one Phase 2b clinical trial of Fovista administered in combination with the anti-VEGF drug Lucentis (ranibizumab).  The Company is also developing its product candidate Zimura for the treatment of patients with geographic atrophy, a form of dry AMD; in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails; and, potentially, in combination with anti-VEGF therapy and Fovista for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation.

2.                       Summary of Significant Accounting Policies

Restatement of Previously Issued Financial Statements

As discussed in Note 13 to the Company’s financial statements, subsequent to the issuance of the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, the Company and the Audit Committee of its Board of Directors concluded that the Company should restate its balance sheets as of December 31, 2014 and March 31, 2015, and its statements of operations, comprehensive income (loss), and cash flows for the three months ended March 31, 2015 to correct the following. In the second quarter of 2014, the Company recorded an income tax benefit by reducing a portion of its valuation allowance against its gross deferred tax assets. In determining the amount of the valuation allowance release, the Company considered anticipated 2015 tax losses which would generate a refund of a portion of federal income taxes paid in 2014. The Company has now determined that, as a matter of accounting principle, the net deferred tax asset recorded on its balance sheets was overstated as of December 31, 2014 and March 31, 2015 and the income tax provision on its statement of operations was understated for the period ended March 31, 2015. The Company’s cash position and operating expenses are not affected.

Basis of Presentation

The accompanying unaudited financial information as of March 31, 2015 and for the three months ended March 31, 2015 and 2014 has been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The December 31, 2014 balance sheet was derived from the Company’s audited financial statements. These interim financial statements should be read in conjunction with the notes to the financial statements contained in the Company’s Annual Report on Form 10-K (“Annual Report”) for 2014, as originally filed with the SEC on March 2, 2015, and as amended on Form 10-K/A and filed with the SEC on July 28, 2015.

In the opinion of management, the unaudited financial information as of March 31, 2015 and for the three months ended March 31, 2015 and 2014, reflects all adjustments, which are normal recurring adjustments, necessary to present a fair statement of financial position, results or operations and cash flows. The results of operations for the three months ended March 31, 2015 and 2014 are not necessarily indicative of the operating results for the full fiscal year or any future period.

Use of Estimates

The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. The amounts of assets and liabilities reported in the Company’s Balance Sheets and the amount of expenses reported for each of the periods presented are affected by estimates and assumptions, which are used for, but not limited to, accounting for share-based compensation and accounting for research and development costs. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of 90 days or less when purchased to be cash equivalents. The carrying amounts reported in the Balance Sheets for cash and cash equivalents are valued at cost, which approximates their fair value.

Available for Sale Securities

The Company considers securities with original maturities of greater than 90 days to be available for sale securities. Available for sale securities are recorded at fair value and unrealized gains and losses are recorded within accumulated other comprehensive income (loss). The estimated fair value of the available for sale securities is determined based on quoted market prices or rates for similar instruments. In addition, the cost of debt securities in this category is adjusted for amortization of premium and accretion of discount to maturity. The Company evaluates securities with unrealized losses to determine whether such losses, if any, are other than temporary.

Revenue Recognition

Collaboration Revenue

Prior to 2014, the Company had not generated any revenue. In May 2014, the Company received an up-front payment of $200.0 million in connection with its licensing and commercialization agreement with Novartis Pharma, AG (the “Novartis Agreement”), which has not been recorded as revenue due to certain contingencies associated with the payment. In each of September 2014 and March 2015, the Company achieved a $50.0 million enrollment-based milestone, or $100.0 million in the aggregate, under the Novartis Agreement. The Company recognized revenue of approximately $41.7 million during the three months ended March 31, 2015, which primarily related to the $50.0 million milestone it achieved in March 2015. The balance of the milestone payment was recorded as deferred revenue. The Company uses the relative selling price method to allocate arrangement consideration to the Company’s performance obligations under the Novartis Agreement. Below is a summary of the components of the Company’s collaboration revenue for the three months ended March 31, 2015 and 2014:

The Company did not recognize any revenue related to its obligation to supply active pharmaceutical ingredient, or API, for Fovista to Novartis during the three months ended March 31, 2015.

In the future, the Company may generate additional revenues from a combination of product sales and license fees, milestone payments, research and development activity-related payments, payments for manufactured material and royalties in connection with the Novartis Agreement. The terms of this agreement and other potential collaboration or commercialization agreements the Company may enter into generally contain multiple elements, or deliverables, which may include (i) licenses, or options to obtain licenses, to certain of the Company’s technology and products, (ii) research and development activities to be performed on behalf of the collaborative partner, and (iii) in certain cases, services in connection with the manufacturing of pre-clinical, clinical or commercial material. Payments to the Company under these arrangements typically include one or more of the following: non-refundable, up-front license fees; option exercise fees; funding of research and/or development efforts; milestone payments; payments for manufactured material; and royalties on future product sales.

When evaluating multiple element arrangements, the Company considers whether the deliverables under the arrangement represent separate units of accounting. This evaluation requires subjective determinations and requires management to make judgments about the individual deliverables and whether such deliverables are separable from the other aspects of the contractual relationship. In determining the units of accounting, management evaluates certain criteria, including whether the deliverables have standalone value, based on the relevant facts and circumstances for each arrangement. The consideration received is allocated among the separate units of accounting using the relative selling price method, and the applicable revenue recognition criteria are applied to each of the separate units.

The Company determines the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (“VSOE”) of selling price, if available, third-party evidence (“TPE”) of selling price if VSOE is not available, or best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. Determining the best estimate of selling price for a

8

Table of Contents

deliverable requires significant judgment. The Company uses BESP to estimate the selling price for licenses to the Company’s proprietary technology, since the Company often does not have VSOE or TPE of selling price for these deliverables. In those circumstances where the Company utilizes BESP to determine the estimated selling price of a license to the Company’s proprietary technology, the Company considers market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed models that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate that is subject to the license. In validating the Company’s BESP, the Company evaluates whether changes in the key assumptions used to determine the BESP will have a significant effect on the allocation of arrangement consideration among multiple deliverables.

When management believes the license to its intellectual property and products has stand-alone value, the Company generally recognizes revenue attributed to the license upon delivery. When management believes such a license does not have stand-alone value from the other deliverables to be provided in the arrangement, the Company generally recognizes revenue attributed to the license on a straight-line basis over the Company’s contractual or estimated performance period, which is typically the term of the Company’s research and development obligations. If management cannot reasonably estimate when the Company’s performance obligation ends, then revenue is deferred until management can reasonably estimate when the performance obligation ends. The periods over which revenue should be recognized are subject to estimates by management and may change over the course of the research and development agreement. Such a change could have a material impact on the amount of revenue the Company records in future periods.

At the inception of arrangements that include milestone payments, the Company evaluates whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, or (2) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone, (b) the consideration relates solely to past performance, and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company evaluates factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

The Company aggregates its milestones into three categories: (i) clinical and development milestones, (ii) regulatory milestones, and (iii) commercial milestones. Clinical and development milestones are typically achieved when a product candidate advances into a defined phase of clinical research or completes such phase or when a contractually specified clinical trial enrollment target is attained. Regulatory milestones are typically achieved upon acceptance of the submission of an application for marketing approval for a product candidate or upon approval to market the product candidate by the U.S. Food and Drug Administration (the “FDA”) or other regulatory authorities. For example, a milestone payment may be due to the Company upon the FDA’s acceptance of a New Drug Application (“NDA”). Commercial milestones are typically achieved when an approved pharmaceutical product reaches certain defined levels of net sales by the licensee, such as when a product first achieves global sales or annual sales of a specified amount.

Revenues from clinical and development and regulatory milestone payments, if the milestones are deemed substantive and the milestone payments are nonrefundable, are recognized upon successful accomplishment of the milestones. With regard to the Novartis Agreement, the Company has concluded that the clinical and development milestones and certain regulatory milestones are not substantive and that the regulatory approval milestones are substantive. Milestone payments received that are not considered substantive are included in the allocable arrangement consideration and are recognized as revenue in proportion to the relative-selling price allocation established at the inception of the arrangement. Revenues from commercial milestone payments are accounted for as royalties and are recorded as revenue upon achievement of the milestone, assuming all other revenue recognition criteria are met.

Concentration of Credit Risk

The Company’s financial instruments that are exposed to concentration of credit risk consist primarily of cash and cash equivalents and available for sale securities. The Company maintains its cash in bank accounts, which generally exceed federally insured limits. The Company maintains its cash equivalents in U.S. Treasury securities with maturities of 90 days or less and in money market funds that invest primarily in U.S. Treasury securities.

The Company’s available for sale securities are also invested in U.S. Treasury securities. The Company has not recognized any losses from credit risks on such accounts during any of the periods presented. The Company believes it is not exposed to significant credit risk on its cash, cash equivalents and available for sale securities.

Foreign Currency Translation

The Company considers the U.S. dollar to be its functional currency. Expenses are translated at the exchange rate on the date the expense is incurred. The effect of exchange rate fluctuations on translating foreign currency assets and liabilities into U.S. dollars is included in the Statements of Operations. Foreign exchange transaction gains and losses are included in the results of operations and are not material in the Company’s financial statements.

Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash and cash equivalents, available for sale securities, accounts payable and accrued expenses approximate their respective fair value due to their short maturities.

Property and Equipment

Property and equipment, which consists mainly of manufacturing and clinical equipment, furniture and fixtures, computers and other equipment, and leasehold improvements, are carried at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the respective assets, generally three to ten years, using the straight-line method rather than a method based on when the payments are made.

Research and Development

Research and development expenses primarily consist of costs associated with the manufacturing, development and clinical testing of Fovista, an anti-platelet derived growth factor (“PDGF”) aptamer that the Company is developing for use in combination with anti-VEGF therapy for treatment of wet AMD, and Zimura, an inhibitor of complement factor C5 that the Company is developing for the treatment of patients with geographic atrophy, a form of dry AMD; in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails; and, potentially, in combination with anti-VEGF therapy and Fovista for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation. Research and development expenses consist of:

·                  external research and development expenses incurred under arrangements with third parties, such as contract research organizations (“CROs”) and other vendors and contract manufacturing organizations for the production of drug substance and drug product; and

·                  employee-related expenses, including salaries, benefits, travel and share-based compensation expense.

Research and development costs also include costs of acquired product licenses and related technology rights where there is no alternative future use, costs of prototypes used in research and development, consultant fees and amounts paid to collaborative partners.

All research and development costs are charged to operations as incurred in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic, or ASC, 730, Research and Development. The Company accounts for non-refundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received, rather than when the payment is made.

The Company anticipates that it will continue to incur significant research and development expenses in connection with conducting its pivotal Phase 3 clinical program for Fovista and if such trials are successful, seeking marketing approval for Fovista.  In addition, the Company expects that it will incur significant expenses related to the completion of process development and manufacturing scale-up activities for Fovista. The Company also anticipates that its research and development expenses will increase as a result of its plan to initiate a Phase 2/3 clinical trial to evaluate the safety and efficacy of Zimura in patients with geographic atrophy in the second half of 2015; the very small Phase 2 trial recently commenced investigating Zimura in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails; and the planned Phase 2 study of Zimura in combination with anti-VEGF therapy and Fovista for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation. In addition, the Company also expects its research and development expenses to increase as it further evaluates the potential benefit of Fovista in wet AMD, when administered in combination with anti-VEGF therapy, and in other ophthalmic diseases and conditions with unmet medical need. The Company expects these expenses to increase as patient enrollment increases in these trials.

Table of Contents

Income Taxes

The Company utilizes the liability method of accounting for deferred income taxes, as set forth in ASC 740-10, Income Taxes—Overall. Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. The Company incurred U.S. federal net operating losses in each year from its inception in 2007 through 2013 and as such, all prior tax years since 2007 remain subject to potential tax examination as the utilization of net operating losses from prior years opens the relevant year to potential audit.

Share-Based Compensation

The Company follows the provisions of ASC 718, Compensation—Stock Compensation, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and non-employee directors, including employee stock options and restricted stock units (“RSUs”). Share-based compensation expense is based on the grant date fair value estimated in accordance with the provisions of ASC 718 and is generally recognized as an expense over the requisite service period, net of forfeitures.

Stock Options

The Company estimates the fair value of stock options granted to employees and non-employee directors on the date of grant using the Black-Scholes option-pricing model. Due to the lack of trading history, the Company’s computation of stock-price volatility is based on the volatility rates of comparable publicly held companies over a period equal to the expected term of the options granted by the Company. The Company’s computation of expected term is determined using the “simplified” method, which is the midpoint between the vesting date and the end of the contractual term. The Company believes that it does not have sufficient reliable exercise data in order to justify the use of a method other than the “simplified” method of estimating the expected exercise term of employee stock option grants. The Company utilizes a dividend yield of zero based on the fact that the Company has never paid cash dividends to stockholders and has no current intentions to pay cash dividends. The risk-free interest rate is based on the zero-coupon U.S. Treasury yield at the date of grant for a term equivalent to the expected term of the option.

For stock options granted as consideration for services rendered by consultants, the Company recognizes expense in accordance with the requirements of ASC 505-50, Equity Based Payments to Non-Employees. Consultant option grants that do not vest immediately upon grant are recorded as an expense over the vesting period of the underlying stock options. At the end of each financial reporting period prior to vesting, the value of these options, as calculated using the Black-Scholes option-pricing model, will be re-measured using the fair value of the Company’s common stock and the non-cash expense recognized during the period will be adjusted accordingly. Since the fair value of options granted to consultants is subject to change in the future, the amount of the future expense will include fair value re-measurements until the stock options are fully vested.

Restricted Stock Units

The Company estimates the fair value of restricted stock units granted to employees using the closing market price of the Company’s common stock on the date of grant.

Share-based compensation expense includes expenses related to stock options and restricted stock units granted to employees, non-employee directors and consultants, and has been reported in the Company’s Statements of Operations as follows:

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. ASU 2014-09 is effective for public entities for annual reporting periods beginning after December 15, 2016 and interim

periods within those periods. Early adoption is not permitted. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. The Company is currently assessing the impact that adopting this new accounting guidance will have on its financial statements and footnote disclosures.

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which defines management’s responsibility to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. The pronouncement is effective for annual reporting periods ending after December 15, 2016 with early adoption permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s financial statements.

3.                       Capitalization

On September 30, 2013, the Company closed its initial public offering of 8,740,000 shares of common stock at a price of $22.00 per share of common stock. The net proceeds to the Company were $175.6 million, after deducting underwriters’ discounts and commissions and other offering expenses. In connection with the closing of the IPO, all of the Company’s shares of redeemable convertible preferred stock outstanding at the time of the offering were automatically converted into 21,038,477 shares of common stock.

On February 18, 2014, the Company closed a follow-on public offering of 2,628,571 shares of common stock at a public offering price of $31.50 per share of common stock. The Company sold 1,900,000 shares and 728,571 shares were sold by selling stockholders, including 342,857 shares sold by the selling stockholders upon the full exercise by the underwriters of their option to purchase additional shares in the follow-on public offering. The net proceeds to the Company were $55.4 million, after deducting underwriters’ discounts and commissions and other offering expenses. The Company did not receive any proceeds from the sale of shares by the selling stockholders in the follow-on public offering.

Basic and diluted net income (loss) per common share is determined by dividing net income (loss) by the weighted average common shares outstanding during the period. For the periods where there is a net loss, stock options, restricted stock units and warrants have been excluded from the calculation of diluted loss per common share because their effect would be anti-dilutive. Therefore, the weighted average shares used to calculate both basic and diluted loss per share would be the same. The following table sets forth the computation of basic and diluted net income (loss) per common share for the periods indicated:

The following potentially dilutive securities have been excluded from the computations of diluted weighted average common shares outstanding for the periods presented, as they would be anti-dilutive:

5.                       Cash, Cash Equivalents and Available for Sale Securities

The Company considers all highly liquid investments purchased with original maturities of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents included cash of $5.3 million and $4.7 million at March 31, 2015 and

12

Table of Contents

December 31, 2014, respectively. Cash and cash equivalents at March 31, 2015 and December 31, 2014 also included investments of $34.3 million and $35.1 million, respectively, in U.S. Treasury securities with original maturities of 90 days or less and investments in money market funds that invest in U.S. Treasury Securities.

The Company held available for sale securities with a fair value totaling $393.7 million and $423.7 million at March 31, 2015 and December 31, 2014, respectively.  These available for sale securities consisted of U.S. Treasury securities and had maturities of greater than 90 days and less than one year. The Company evaluates securities with unrealized losses, if any, to determine whether such losses are other than temporary. The Company has determined that there were no other than temporary declines in fair values of its investments as of March 31, 2015. The Company classifies these securities as available for sale, however, the Company does not currently intend to sell its investments and the Company believes it is more likely than not that the Company will recover the carrying value of these investments.

Available for sale securities, including carrying value and estimated fair values, are summarized as follows:

The Company’s available for sale securities are reported at fair value on the Company’s balance sheet. Unrealized gains and losses are reported within accumulated other comprehensive income (loss) in the statements of comprehensive income (loss).  The changes in accumulated other comprehensive loss associated with the unrealized loss on available for sale securities during the three months ended March 31, 2015 and March 31,2014 were as follows:

6.                       Licensing and Commercialization Agreement with Novartis Pharma AG

On May 19, 2014, the Company entered into a licensing and commercialization agreement with Novartis Pharma AG. Under the Novartis Agreement, the Company granted Novartis exclusive rights under specified patent rights, know-how and trademarks controlled by the Company to manufacture, from bulk active pharmaceutical ingredient, or API, supplied by the Company, standalone Fovista products and products combining Fovista with an anti-VEGF product to which Novartis has rights in a co-formulated product, for the treatment, prevention, cure or control of any human disease, disorder or condition of the eye, and to develop and commercialize those licensed products in all countries outside of the United States (the “Novartis Territory”). The Company has agreed to use commercially reasonable efforts to complete its ongoing pivotal Phase 3 clinical program for Fovista and Novartis has agreed to use commercially reasonable efforts to develop a standalone Fovista product and a co-formulated product containing Fovista and an anti-VEGF product to which Novartis has rights, as well as a pre-filled syringe presentation of such products and to use commercially reasonable efforts, subject to obtaining marketing approval, to commercialize licensed products in the Novartis Territory in accordance with agreed development and marketing plans. Novartis has also granted the Company options, subject to specified limitations, and to the extent such rights are controlled by Novartis, to obtain exclusive rights from Novartis to develop and commercialize in the United States the co-formulated and pre-filled syringe products developed by Novartis. The Company and Novartis have each granted the other options, subject to specified limitations, to obtain access to study data from certain clinical trials of licensed products that the Company or Novartis may conduct, including for use by the other in regulatory filings in its territory. The Company has agreed to exclusively supply Novartis, and Novartis has agreed to exclusively purchase from the Company, its clinical

Table of Contents

and commercial requirements for the bulk API for Fovista for use in licensed products in the Novartis Territory. The Company has agreed not to commercialize any product comprising Fovista or any other anti-PDGF product in the ophthalmic field in the Novartis Territory.

Novartis paid the Company a $200.0 million upfront fee upon execution of the Novartis Agreement. Novartis is also obligated to pay the Company up to an aggregate of $130.0 million if the Company achieves specified patient enrollment-based milestones for its Phase 3 clinical program for Fovista, of which, $50.0 million was received by the Company in October 2014 and $50.0 million was achieved in March 2015 and received in April 2015, and up to an aggregate of an additional $300.0 million upon achievement of specified regulatory approval milestones, including reimbursement approval, in certain countries in the Novartis Territory. In addition, Novartis has agreed to pay the Company up to an aggregate of an additional $400.0 million if Novartis achieves specified sales milestones in the Novartis Territory. Novartis also is obligated to pay the Company royalties with respect to standalone Fovista products and combination Fovista products that Novartis successfully commercializes. The Company will receive royalties at a mid-thirties percentage of net sales of standalone Fovista products and a royalty of approximately equal value for sales of combination Fovista products. Such royalties are subject to customary deductions, credits, and reductions for lack of patent coverage or market exclusivity. Novartis’s obligation to pay such royalties will continue on a licensed product-by-licensed product and country-by-country basis until Novartis’s last actual commercial sale of such licensed product in such country. The Company will continue to be responsible for royalties it owes to third parties on sales of Fovista products.

Novartis has agreed to pay the Company’s manufacturing costs plus a specified percentage margin for supplies of the bulk API for Fovista that the Company supplies to Novartis. If the Company or Novartis exercises each of their respective rights to obtain access to study data from clinical trials conducted by the other party, the party exercising the option will be obligated to pay the other party’s associated past development costs and share with such other party any future associated development costs. If the Company exercises its option to obtain Novartis-controlled rights to develop, manufacture and commercialize any co-formulated Fovista product in the United States, the Company will be obligated to pay a specified percentage of Novartis’s associated past development costs and share with Novartis any future associated development costs. The Company and Novartis will also need to negotiate and agree on financial and other terms that would apply to such rights. If the Company exercises its option to obtain Novartis-controlled rights to develop and commercialize a pre-filled syringe product in the United States, the Company will be obligated to either enter into a supply agreement with Novartis under which the Company will pay Novartis its manufacturing cost plus a specified percentage margin for supplies of Fovista products in pre-filled syringes that Novartis supplies to the Company, or obtain supplies of products in pre-filled syringes from a third party manufacturer and pay Novartis a low single-digit percentage of the Company’s net sales of such products.

The Company has retained control over the design and execution of its pivotal Phase 3 clinical program for Fovista and remains responsible for funding the costs of that program, subject to Novartis’s responsibility to provide Lucentis, an anti-VEGF agent to which Novartis has rights in the Novartis Territory, for use in the Phase 3 trials already initiated and in other Phase 2 and Phase 3 clinical trials in the Novartis Territory following the effective date of the Novartis Agreement. Novartis will have control over, and will be responsible for the costs of, all other clinical trials that may be required to obtain marketing approvals in the Novartis Territory for licensed products under the agreement. Novartis is also responsible for costs associated with co-formulation development, pre-filled syringe development and other development costs in the Novartis Territory, excluding regulatory filing fees in the European Union for the standalone Fovista product, for which the Company will be responsible.

The Novartis Agreement, unless earlier terminated by the Company or Novartis, will expire upon the expiration of Novartis’s obligation to pay the Company royalties on net sales of licensed products. The Company and Novartis each may terminate the Novartis Agreement if the other party materially breaches the agreement and does not cure such breach within a specified cure period, if the other party experiences any specified insolvency event, if the other party challenges or assists a third party in challenging the validity or enforceability of certain patent rights controlled by the terminating party, or if the parties are prevented in any manner that materially adversely affects the progression of the development or commercialization of licensed products for a specified period as a result of specified governmental actions. Novartis may terminate the Novartis Agreement at any time without cause, or within a specified period after a change in control of the Company, as defined in the Novartis Agreement, or for specified safety reasons, effective at the end of a specified period following Novartis’s written notice to the Company of Novartis’s election to terminate the agreement. The Company may also terminate the agreement if Novartis determines to seek marketing approval of an alternative anti-PDGF product in the Novartis Territory as more fully described below. If the Company elects to terminate the Novartis Agreement because specified governmental actions prevent the parties from materially progressing the development or commercialization of licensed products as described above, the Company will be required to pay a substantial termination fee, with the specific amount of such fee determined based on the effective date of the termination. Following any termination, all rights to Fovista that the Company granted to Novartis, including, without limitation, the right to commercialize standalone Fovista products in the Novartis Territory, will revert to the Company, Novartis will perform specified activities in connection with transitioning to the Company the rights and responsibilities for the continued development, manufacture and commercialization of the standalone Fovista product for countries in

14

Table of Contents

the Novartis Territory, and the parties will cooperate on an orderly wind down of development and commercialization activities for other licensed products in the Novartis Territory.

Novartis has agreed to specified limitations on its ability to in-license, acquire or commercialize any anti-PDGF product that does not contain Fovista (an “Alternative Anti-PDGF Product”) in the Novartis Territory and, to the extent Novartis develops, in-licenses or acquires such a product, to make such product available to the Company in the United States under specified option conditions. If the Company exercises its option, the Company will be obligated to make certain payments to Novartis, including specified milestone and royalty payments. The amounts of such payments will vary based on the product’s stage of clinical development at the time the Company exercise its option, whether the product is a standalone or combination product and whether Novartis exercises an option to co-promote such product in the United States. If Novartis determines to seek marketing approval of an Alternative Anti-PDGF Product in the Novartis Territory, the Company will, subject to specified limitations, have the option to terminate the Novartis Agreement, convert Novartis’s exclusive licenses into non-exclusive licenses, or elect to receive a royalty on sales of such product by Novartis. If the Company elects to terminate the Novartis Agreement, Novartis will, subject to specified limitations, be required to pay to the Company, certain payments based on achievement, with respect to such product, of the milestones that would have otherwise applied to licensed products under the Novartis Agreement.

Activities under the licensing and commercialization Novartis Agreement were evaluated under ASC 605-25, Revenue Recognition—Multiple Element Arrangements (“ASC 605-25”) (as amended by ASU 2009-13, Revenue Recognition (“ASU 2009-13”)) to determine if they represented a multiple element revenue arrangement. The Novartis Agreement includes the following deliverables: (1) an exclusive license to commercialize Fovista outside the United States (the “License Deliverable”); (2) the performance obligation to conduct research and development activities related to the Phase 3 Fovista clinical trials and certain Phase 2 trials for Fovista (the “R&D Activity Deliverable”); (3) the performance obligation to supply API to Novartis for development and manufacturing purposes (the “Manufacturing Deliverable”) and (4) the Company’s obligation to participate on the joint operating committee established under the terms of the Novartis Agreement and related subcommittees (the “Joint Operating Committee Deliverable”). Novartis has the right, subject to the certain approval rights of the Company, to sublicense the exclusive royalty-bearing license to commercialize Fovista in the Novartis Territory. The Company’s obligation to provide access to clinical and regulatory information as part of the License Deliverable includes the obligation to provide access to all clinical data, regulatory filings, safety data and manufacturing data to Novartis which is necessary for commercialization of Fovista in the Novartis Territory. The R&D Activity Deliverable includes the right and responsibility for the Company to conduct the Phase 3 Fovista clinical program and other studies of Fovista in the Novartis Territory which are necessary or desirable for regulatory approval or commercialization of Fovista. The Manufacturing Deliverable includes the obligation for the Company to supply API to Novartis for development and manufacturing purposes, for which Novartis has agreed to pay the Company’s manufacturing costs, plus a specified margin. The Joint Operating Committee Deliverable includes the obligation to participate in the Joint Operating Committee and related subcommittees at least through the first anniversary of regulatory approval in the European Union. All of these deliverables were deemed to have stand-alone value and to meet the criteria to be accounted for as separate units of accounting under ASC 605-25. Factors considered in this determination included, among other things, the subject of the licenses and the research and development and commercial capabilities of Novartis. Accordingly, each unit will be accounted for separately.

Options are considered substantive if, at the inception of the arrangement, the Company is at risk as to whether the collaboration partner will choose to exercise the option. Factors that the Company considers in evaluating whether an option is substantive include the overall objective of the arrangement, the benefit the collaborator might obtain from the arrangement without exercising the option, the cost to exercise the option and the likelihood that the option will be exercised. For arrangements under which an option is considered substantive, assuming the option is not priced at a significant and incremental discount, the Company does not consider the item underlying the option to be a deliverable at the inception of the arrangement and the associated option fees are not included in allocable arrangement consideration. Conversely, for arrangements under which an option is not considered substantive or if an option is priced at a significant and incremental discount, the Company would consider the item underlying the option to be a deliverable at the inception of the arrangement and a corresponding amount would be included in allocable arrangement consideration. All of the options included in the Novartis Agreement have been determined to be substantive, and none of the options are priced at a significant and incremental discount.

The Novartis Agreement provides that, if the Company elects to terminate the Novartis Agreement because specified governmental actions prevent the parties from materially progressing the development or commercialization of licensed products as described above, the Company will be required to pay a substantial termination fee, with the specific amount of such fee determined based on the effective date of the termination. The Company has concluded that this termination provision constitutes a contingent event that was unknown at the inception of the agreement. As such, the Company has recorded the $200.0 million upfront payment in deferred revenue, long-term until such time that the contingency related to this termination provision is resolved. The Company believes the enrollment milestones and certain of the regulatory milestones that may be achieved under the Novartis Agreement do not meet the recognition criteria within the definition of a milestone included in ASU 2010-17, Revenue Recognition—Milestone Method,

15

Table of Contents

and therefore, payments received for the achievement of the enrollment milestones in excess of the termination fee will be included in the allocable arrangement consideration and allocated to the deliverables based upon BESP using the relative selling price method.

The Company believes the remaining regulatory approval milestones that may be achieved under the Novartis Agreement are consistent with the definition of a milestone included in ASU 2010-17, Revenue Recognition—Milestone Method, and, accordingly, the Company will recognize payments related to the achievement of such milestones, if any, when the applicable milestone is achieved. Factors considered in this determination included scientific and regulatory risks that must be overcome to achieve each milestone, the level of effort and investment required to achieve each milestone, and the monetary value attributed to each milestone.

In each of September 2014 and March 2015, the Company achieved a $50.0 million enrollment-based milestone, or $100.0 million in aggregate, under the Novartis Agreement. The Company recognized revenue of approximately $41.7 million during the three months ended March 31, 2015, which primarily related to the $50.0 million milestone it achieved in March 2015. The balance of the milestone payment was recorded as deferred revenue. Using the relative selling price method, the Company allocated revenue of $38.1 million to the license it delivered to Novartis under the Novartis Agreement, $3.6 million to research and development activities that the Company performed under the Novartis Agreement during the three months ended March 31, 2015, and a de minimis amount of revenue associated with its joint operating committee participation obligation during the same period.

7.                       Financing Agreement with Novo A/S

In May 2013, the Company entered into a Purchase and Sale Agreement with Novo A/S, which is referred to as the Novo Agreement, pursuant to which the Company had the ability to obtain financing in three tranches in an amount of up to $125.0 million in return for the sale to Novo A/S of aggregate royalties of worldwide sales of (a) Fovista, (b) Fovista-Related Products, and (c) Other Products (each as defined in the Novo Agreement), calculated as low to mid-single digit percentages of net sales, with the royalty percentage determined by the amount of funding provided by Novo A/S.

The Novo Agreement provided for up to three separate purchases for a purchase price of $41.7 million each, at a first, second and third closing, for an aggregate purchase price of $125.0 million. In each purchase, Novo A/S would acquire rights to a low single digit percentage of net sales. In each of May 2013, January 2014 and November 2014, the Company received cash payments of $41.7 million, or $125.0 million in the aggregate, and Novo A/S received, in the aggregate, a right to receive royalties on net sales of Fovista at a mid-single digit percentage.

The royalty payment period covered by the Novo Agreement begins on commercial launch and ends, on a product-by-product and country-by-country basis, on the latest to occur of (i) the 12th anniversary of the commercial launch, (ii) the expiration of certain patent rights and (iii) the expiration of the regulatory exclusivity for each product in each country.

Under the terms of the Novo Agreement, the Company is not required to reimburse or otherwise compensate Novo A/S through any means other than the agreed royalty entitlement. In addition, the Company does not, under the terms of the Novo Agreement, have the right or obligation to prepay Novo A/S in connection with a change of control of the Company or otherwise.

The $125.0 million in aggregate proceeds from the three financing tranches under the Novo Agreement represents the full funding available under the Novo Agreement, and has been recorded as a liability on the Company’s Balance Sheet as of March 31, 2015, in accordance with ASC 730, Research and Development. Because there is a significant related party relationship between the Company and Novo A/S, the Company is treating its obligation to make royalty payments under the Novo Agreement as an implicit obligation to repay the funds advanced by Novo A/S. As the Company makes royalty payments in accordance with the Novo Agreement, it will reduce the liability balance. At the time that such royalty payments become probable and estimable, and if such amounts exceed the liability balance, the Company will impute interest accordingly on a prospective basis based on such estimates, which would result in a corresponding increase in the liability balance.

The Novo Agreement requires the establishment of a Joint Oversight Committee in the event that Novo A/S does not continue to have a representative on the Company’s board of directors. The Joint Oversight Committee would have responsibilities that include “discussion and review” of all matters related to Fovista research, development, regulatory approval and commercialization, but there is no provision either implicit or explicit that gives the Joint Oversight Committee or its members decision-making authority.

8.                       Income Taxes

The Company utilizes the liability method of accounting for deferred income taxes. Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. A valuation allowance is established against deferred tax assets when, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company’s policy is to record interest and penalties on uncertain tax positions as income tax expense. As of March 31, 2015 and December 31, 2014, the Company

16

Table of Contents

does not believe any material uncertain tax positions were present. Accordingly, interest and penalties have not been accrued due to an uncertain tax position.

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of taxable income during the periods in which the temporary differences representing net future deductible amounts become deductible, and is impacted by the Company’s ability to carryback losses to 2014, the only year in which the Company had taxable income.  The Company is currently projecting tax losses in 2015 and in future years.  The Company recorded net income of $6.6 million during the three months ended March 31, 2015, which included a provision for income taxes of approximately $1.0 million.  However, due to the Company’s projected tax loss in 2015, the Company expects to record an income tax benefit for the full year. The Company currently expects to realize certain of its net deferred tax assets recorded as of March 31, 2015 due to the Company’s ability to carryback its projected federal tax losses to 2014. Because of the Company’s history of losses and lack of other positive evidence to support taxable income after the 2014 tax year, the Company has recorded a valuation allowance against those remaining deferred tax assets that are not expected to be realized.

Deferred tax assets relating to employee share-based compensation deductions were reduced to reflect exercises of non-qualified stock option grants and vesting of restricted stock. Although certain of these deductions were reported on the corporate tax returns and increased net operating losses, these related tax benefits were not recognized for financial reporting purposes.

9.                       Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value standard also establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows:

·                           Level 1—inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. The Company’s Level 1 assets consist of investments in U.S. Treasury money market funds and U.S. Treasury securities.

·                           Level 2—inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability.

·                           Level 3—inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability.

The following table presents, for each of the fair value hierarchy levels required under ASC 820, the Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2015:

The following table presents, for each of the fair value hierarchy levels required under ASC 820, the Company’s assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2014:

10.                Stock Option and Compensation Plans

The Company adopted its 2007 Stock Incentive Plan (the “2007 Plan”) for employees, directors and consultants for the purpose of advancing the interests of the Company stockholders by enhancing its ability to attract, retain and motivate persons who are expected to make important contributions to the Company. The 2007 Plan provided for the granting of stock option awards, restricted stock awards, and other stock-based and cash-based awards. Following the effectiveness of the 2013 Stock Incentive Plan described below in connection with the closing of the Company’s initial public offering, the Company is no longer granting additional awards under the 2007 Plan.

In August 2013, the Company’s board of directors adopted and the Company’s stockholders approved the 2013 stock incentive plan (the “2013 Plan”), which became effective immediately prior to the closing of the Company’s initial public offering. The 2013 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock-based awards. Upon effectiveness of the 2013 Plan, the number of shares of the Company’s common stock that were reserved for issuance under the 2013 Plan was the sum of (1) such number of shares (up to approximately 3,359,641 shares) as is equal to the sum of 739,317 shares (the number of shares of the common stock then available for issuance under the 2007 Plan), and such number of shares of the Company’s common stock that are subject to outstanding awards under the 2007 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right plus (2) an annual increase, to be added the first business day of each fiscal year, beginning with the fiscal year ending December 31, 2014 and continuing until, and including, the fiscal year ending December 31, 2023, equal to the lowest of 2,542,372 shares of the Company’s common stock, 4% of the number of shares of the Company’s common stock outstanding on the first day of the fiscal year and an amount determined by its board of directors. The Company’s employees, officers, directors, consultants and advisors are eligible to receive awards under the 2013 Plan. However, incentive stock options may only be granted to employees of the Company.

In connection with the evergreen provisions of the 2013 Plan, the number of shares available for issuance under the 2013 Plan was increased by approximately 1,360,000 effective as of January 1, 2015. As of March 31, 2015, the Company had approximately 1,350,000 shares available for grant under the 2013 Plan.

Cash proceeds from, and the aggregate intrinsic value of, stock options exercised during the three months ended March 31, 2015 and 2014, respectively, were as follows:

A summary of the stock options outstanding and exercisable as of March 31, 2015 is as follows:

18

Table of Contents

In connection with stock option awards granted to employees, the Company recognized share-based compensation expense of approximately $3.9 million and $2.5 million for the three months ended March 31, 2015 and 2014, respectively, net of expected forfeitures.  As of March 31, 2015, there was approximately $44.3 million of unrecognized compensation costs, net of estimated forfeitures, related to stock option awards to employees, which are expected to be recognized over a remaining weighted average period of 3.1 years.

In connection with stock options awards granted to consultants, the Company recognized approximately $0.7 million and $0.2 million in share-based compensation expense during the three months ended March 31, 2015 and 2014, respectively, net of expected forfeitures.  As of March 31, 2015, there was approximately $5.1 million of unrecognized compensation costs, net of estimated forfeitures, related to stock option award granted to consultants which are expected to be recognized over a remaining weighted average period of 2.2 years.

As of March 31, 2015, the Company had approximately 172,000 restricted stock units outstanding. In connection with restricted stock units granted to employees, the Company recognized share-based compensation of approximately $0.5 million during the three months ended March 31, 2015, net of expected forfeitures. The Company did not recognize any share-based compensation expense related to restricted stock units during the three months ended March 31, 2014. As of March 31, 2015, there was approximately $6.3 million of unrecognized compensation costs, net of estimated forfeitures, related to restricted stock units granted to employees to be recognized over a remaining weighted average period of 3.6 years.

11.                Property and Equipment

Property and equipment at March 31, 2015 and December 31, 2014 were as follows:

For the three months ended March 31, 2015 and 2014, depreciation expense was $56 thousand and $12 thousand, respectively.

12.                Subsequent event

In April 2015, the Company entered into a sublease agreement (the “Sublease”) with Otsuka America Pharmaceutical, Inc., (“Otsuka”), as sublandlord, pursuant to which the Company will sublease from Otsuka approximately 35,200 square feet of office space in Princeton, New Jersey.  The term of the Sublease will expire in March 2021, and is subject to an early termination right in favor of the Company.  The termination right is exercisable prior to April 2017 and, if exercised, would be effective in February 2018 and would trigger a termination payment by the Company of approximately $1.2 million.  The Company has agreed to pay aggregate rental fees of approximately $6.9 million over the term of the Sublease, subject to certain partial rent abatements and offsets by the sublandlord during the first three years of the Sublease.  The Company is also liable for taxes, operating expenses and utility and other charges related to the subleased premises.

13.                               Restatement of Previously Issued Financial Statements

Subsequent to the issuance of the Company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2015, the Company and the audit committee of the Board of Directors concluded that the Company should restate its balance sheets as of March 31, 2015 and December 31, 2014, and its statements of operations, comprehensive income (loss), and cash flows for the three months ended March 31, 2015 to correct the following errors:

In the second quarter of 2014, the Company recorded an income tax benefit by reducing a portion of its valuation allowance against its gross deferred tax assets.  In determining the amount of the valuation allowance release, the Company considered anticipated 2015 tax losses which would generate a refund of a portion of federal income taxes paid in 2014.  The Company has now determined that, as a matter of accounting principle, the net deferred tax asset recorded on its balance sheet was overstated as of and for the periods ending December 31, 2014 and March 31, 2015 and the income tax provision on its statement of operations was understated as of and for the period ending March 31, 2015. The Company’s cash position and operating expenses were not affected.

The following tables summarize the effect of the restatement by major financial statement line as of March 31, 2015 and for the three months then ended:

Overview

We are a biopharmaceutical company specializing in the development of novel therapeutics to treat diseases of the back of the eye, with a focus on developing therapeutics for age-related macular degeneration, or AMD. Our most advanced product candidate is Fovista, which is in Phase 3 clinical development for use in combination with anti-VEGF therapy that represents the current standard of care for the treatment of wet AMD. We have completed one Phase 1 and one Phase 2b clinical trial of Fovista administered in combination with the anti-VEGF drug Lucentis. We are also developing our product candidate Zimura for the treatment of patients with geographic atrophy, a form of dry AMD; in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails; and, potentially, in combination with anti-VEGF therapy and Fovista, for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation. We have recently begun work to investigate the possibility of an ophthalmic formulation for tivozanib, an anti-VEGF compound for which we have an option for a license.

Our pivotal Phase 3 clinical program for Fovista consists of three separate Phase 3 clinical trials to evaluate the safety and efficacy of Fovista administered in combination with anti-VEGF therapy for the treatment of wet AMD compared to anti-VEGF monotherapy. Two of these trials are evaluating Fovista in combination with Lucentis and the other is evaluating Fovista in combination with Eylea (aflibercept) or Avastin (bevacizumab). We recently announced that we completed patient recruitment in one of the two trials evaluating Fovista in combination with Lucentis. We are continuing to actively enroll patients in the other two trials. We expect that patient recruitment in the second trial evaluating Fovista in combination with Lucentis will be completed approximately by the end of the third quarter of 2015. The third trial in the Phase 3 clinical program, which is evaluating Fovista administered in combination with either Eylea or Avastin, is recruiting patients as expected, and we anticipate the duration of recruitment for this clinical trial to be substantially similar to that of the two clinical trials investigating Fovista administered in combination with Lucentis. Our timing projections for the trials that are continuing to enroll patients assume that there is no impact on recruitment related to the summer season or the initiation or activation of competing trials. We plan to enroll a total of approximately 1,866 patients at more than 225 centers internationally across the three trials. Based on our estimates regarding patient enrollment, we expect initial, top-line data from our two Phase 3 clinical trials of Fovista in combination with Lucentis to be available in 2016, approximately one year after the enrollment of the last patient in the second Phase 3 clinical trial of Fovista in combination with Lucentis, plus the time needed for database closure and analysis of top-line data.  In addition to being identical with respect to the trial design in the first year of the clinical trials, both of the Phase 3 clinical trials of Fovista in combination with Lucentis are investigating the superiority of Fovista in combination with Lucentis compared to Lucentis monotherapy. Accordingly, the database from both trials of Fovista in combination with Lucentis will be locked and analyzed together which will allow for the analysis of multiple relevant endpoints in accordance with the statistical analysis plan.

Our development strategy for Fovista is to be agnostic with respect to the choice of the anti-VEGF therapy administered in combination with Fovista. In our third Phase 3 clinical trial, we are investigating Fovista in combination with either Eylea or Avastin compared to administration of either Eylea or Avastin alone in the control arm. Our Phase 2b trial utilized Lucentis as the only anti-VEGF therapy because Eylea was not yet approved and Avastin’s non-inferiority status compared to Lucentis was not yet established at the time the Phase 2b clinical trial commenced. Therefore, in order to gain more experience with Fovista when combined with Eylea or Avastin prior to starting a pivotal Phase 3 clinical trial, the Phase 3 clinical trial of Fovista in combination with Eylea or Avastin started later (May 2014) than the Phase 3 clinical trials of Fovista in combination with Lucentis (August 2013). This time period of approximately nine months allowed us to complete the assessment of initial preclinical and clinical studies and ensure compatibility of Eylea or Avastin when administered in combination with Fovista.

Our key objective and plan is to make Fovista commercially available to physicians for their patients with wet AMD as quickly as possible, subject to obtaining favorable data from the Phase 3 clinical program. We are continuing to explore various regulatory filing options. We anticipate that we will initially submit a New Drug Application, or NDA, to the U.S. Food and Drug Administration, or FDA, for Fovista in combination with Lucentis based upon data from the two Phase 3 clinical trials of Fovista in combination with Lucentis and subsequently submit an amendment to the NDA with data from the Phase 3 clinical trial of Fovista in combination with Eylea or Avastin, subject to obtaining favorable data from these trials. Alternatively, we may choose to file a supplemental NDA for Fovista in combination with Eylea or Avastin following FDA review of the NDA for Fovista in combination with Lucentis.

We also initiated, in the third quarter of 2014, a Phase 2a open-label trial designed to investigate the potential effect of the administration of Fovista in combination with anti-VEGF therapy in reducing the formation of subretinal fibrosis in wet AMD patients, and, in the fourth quarter of 2014, a Phase 2a clinical trial, which is evaluating the potential benefit of Fovista in wet AMD, when administered in combination with anti-VEGF therapy, in the reduction of treatment burden. We are also planning additional clinical trials to assess the potential therapeutic benefit of Fovista in other ophthalmic conditions.

On May 19, 2014, we entered into a licensing and commercialization agreement with Novartis Pharma AG, which we refer to as the Novartis Agreement. Under the Novartis Agreement, we granted Novartis exclusive rights under specified patent rights, know-how and trademarks controlled by us to manufacture, from bulk active pharmaceutical ingredient, or API, supplied by us, standalone Fovista products and products combining Fovista with an anti-VEGF product to which Novartis has rights in a co-formulated product, for the treatment, prevention, cure or control of any human disease, disorder or condition of the eye, and to develop and commercialize those licensed products in all countries outside of the United States, which we refer to as the Novartis Territory. We have agreed to use commercially reasonable efforts to complete our ongoing pivotal Phase 3 clinical program for Fovista and Novartis has agreed to use commercially reasonable efforts to develop a standalone Fovista product and a co-formulated product containing Fovista and an anti-VEGF to which Novartis has rights, as well as a pre-filled syringe presentation of such products and to use commercially reasonable efforts, subject to obtaining marketing approval, to commercialize licensed products in the Novartis Territory in accordance with agreed development and marketing plans.

Novartis paid us a $200.0 million upfront fee upon execution of the Novartis Agreement. Novartis is also obligated to pay us up to an aggregate of $130.0 million if we achieve specified patient enrollment-based milestones for our Phase 3 clinical program for Fovista, $50.0 million of which we achieved in September 2014 and $50.0 million of which we achieved in March 2015, and up to an aggregate of an additional $300.0 million upon achievement of specified marketing approval milestones in certain countries in the Novartis Territory. In addition, Novartis has agreed to pay us up to an aggregate of an additional $400.0 million if Novartis achieves specified sales milestones in the Novartis Territory. Novartis also is obligated to pay us royalties with respect to standalone Fovista products and combination Fovista products that Novartis successfully commercializes. We will receive royalties at a mid-thirties percentage of net sales of standalone Fovista products and a royalty of approximately equal value for sales of combination Fovista products. Such royalties are subject to customary deductions, credits, and reductions for lack of patent coverage or market exclusivity. Novartis’s obligation to pay such royalties will continue on a licensed product-by-licensed product and country-by-country basis until Novartis’s last actual sale of such licensed product in such country. We will continue to be responsible for royalties we owe to third parties on sales of Fovista products.

We have retained control over the design and execution of our pivotal Phase 3 clinical program for Fovista and remain responsible for funding the costs of that program, subject to Novartis’s responsibility to provide Lucentis, an anti-VEGF agent to which Novartis has rights in the Novartis Territory, for use in the Phase 3 trials already initiated and in other Phase 2 and Phase 3 clinical trials in the Novartis Territory following the effective date of the Novartis Agreement. Novartis will have control over, and will be responsible for the costs of, all other clinical trials that may be required to obtain marketing approvals in the Novartis Territory for licensed products under the agreement. Novartis is also responsible for costs associated with co-formulation development, pre-filled syringe development and other development costs in the Novartis Territory, but excluding regulatory filing fees in the European Union for the standalone Fovista product, for which we will be responsible.

We plan to initiate a Phase 2/3 clinical trial to evaluate the safety and efficacy of Zimura monotherapy in patients with geographic atrophy in the second half of 2015. We also initiated in late 2014 a very small, open-label Phase 2 trial investigating Zimura administered in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, or PCV, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy has failed.

We were incorporated and commenced active operations in 2007. Our operations to date have been primarily limited to organizing and staffing our company, acquiring rights to product candidates, business planning, raising capital and developing Fovista and Zimura. We acquired our rights to Fovista from (OSI) Eyetech, Inc., or Eyetech, in July 2007. The acquisition included an assignment of license rights and obligations under an agreement with Archemix Corp. We have licensed rights to our product candidate Zimura from Archemix Corp. Since inception, we have incurred significant operating losses. As of March 31, 2015, we had an accumulated deficit of $293.2 million.  While we had net income of $6.6 million for the three months ended March 31, 2015, we reported a net loss of $116.8 million for the year ended December 31, 2014 and expect to continue to incur significant operating losses in 2015 and in the future. We have not generated any revenues from product sales and have financed our operations primarily through private placements of our preferred stock, venture debt borrowings, funding under our royalty purchase and sale agreement with Novo A/S, which we refer to as the Novo Agreement, our initial public offering of common stock, which we closed in September 2013, our follow-on public offering of common stock, which we closed in February 2014, and funds we received under the Novartis Agreement. We received net proceeds from our initial public offering of $175.6 million, after deducting underwriting discounts and commissions and other offering expenses payable by us. We received net proceeds from the follow-on public offering of $55.4 million, after deducting underwriting discounts and commissions and other offering expenses payable by us. We have received $125.0 million of funding under the Novo Agreement, which constitutes the full amount of funding under that agreement. We also received an upfront payment of $200.0 million from Novartis upon the execution of the Novartis Agreement and enrollment-based milestone payments of $50.0 million in October 2014 and $50.0 million in April 2015, the latter milestone having been achieved in March 2015.

We expect our expenses to continue to increase substantially, particularly as we continue the development of Fovista in our Phase 3 clinical program and other additional clinical trials evaluating Fovista for the treatment of wet AMD. We initiated our pivotal Phase 3 clinical program for Fovista in August 2013. We plan to enroll a total of approximately 1,866 patients for this program. In addition, we also expect our expenses to increase as we further evaluate the potential benefit of Fovista in wet AMD, when administered in combination with anti-VEGF therapy, and in other ophthalmic diseases and conditions with unmet need and pursue the development of Zimura for the treatment of geographic atrophy, a form of dry AMD; in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails; and, potentially, in combination with anti-VEGF therapy and Fovista, for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation. We expect these expenses to increase as patient enrollment increases in these clinical trials and as we manufacture validation production batches of API and drug product for Fovista. In addition, our expenses will increase prior to obtaining marketing approval for Fovista as we expand our infrastructure to support commercial operations and, if we obtain marketing approval for Fovista, Zimura or any other product candidate that we may develop, we expect our commercialization expenses related to product sales, marketing, distribution and manufacturing to increase significantly. We are also exploring the possibility of an ophthalmic formulation for tivozanib, an anti-VEGF compound for which we have an option to obtain a license. We are party to agreements, specifically an asset acquisition agreement with OSI (Eyetech), Inc., which agreement is now held by OSI Pharmaceuticals, LLC, a subsidiary of Astellas US, LLC, and license agreements with Archemix Corp. and Nektar Therapeutics, that impose significant milestone payment obligations on us in connection with our achievement of specific clinical, regulatory and commercial milestones with respect to Fovista and Zimura. Furthermore, we are incurring and expect to continue to incur additional costs associated with operating as a public company, hiring additional personnel and expanding our facilities. These costs include significant legal, accounting, and investor and public relations expenses, as well as increased insurance premiums.  See “—Liquidity and Capital Resources — Funding Required” for a discussion of factors affecting our future capital requirements.

Our ability to become and remain profitable depends on our ability to generate revenue in excess of our expenses. We do not expect to generate and maintain significant product revenue unless, and until, we obtain marketing approval for, and commercialize, Fovista, Zimura or other product candidates that we may develop. We may be unsuccessful in our efforts to develop and commercialize these product candidates. Even if we succeed in developing and commercializing one or more of our product candidates, we may never achieve sufficient sales revenue to achieve or maintain profitability. Our capital requirements will also depend on many other factors, including whether we pursue the acquisition or in-licensing and subsequent development of additional product candidates or technologies. We may need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.

Financial Operations Overview

Revenue

Prior to 2014, we had not generated any revenue. In May 2014, we received an up-front payment of $200.0 million in connection with the Novartis Agreement, which has not been recorded as revenue due to certain contingencies associated with the payment.  In each of September 2014 and March 2015, we earned a $50.0 million enrollment-based milestone, or $100.0 million in aggregate, under the Novartis Agreement. We recognized approximately $41.7 million as collaboration revenue during the three months ended March 31, 2015. Using the relative selling price method, we allocated revenue of $38.1 million to the license we delivered to Novartis under the Novartis Agreement, $3.6 million to the research and development activities we performed under the Novartis Agreement during the three months ended March 31, 2015, and a de minimis amount of revenue associated with our joint operating committee participation obligation during the same period. In the future, we may generate additional revenue from a combination of product sales and license fees, milestone payments and research and development activity-related payments, payments for manufactured material and royalties in connection with the Novartis Agreement. We expect that any revenue we generate will fluctuate from quarter to quarter as a result of the timing and amount of certain milestone and other payments, if any, that we may receive from Novartis and the amount and timing of payments that we receive upon the sale of our products, to the extent any are successfully commercialized. We do not expect to generate revenue from product sales until 2017 at the earliest. If we fail to complete the development of Fovista, Zimura or other product candidates we may develop, in a timely manner or obtain regulatory approval for them, our ability to generate future revenue and our results of operations and financial position, would be materially adversely affected.

Research and Development Expenses

Research and development expenses primarily consist of costs associated with the development and clinical testing of Fovista and Zimura. Our research and development expenses consist of:

·                           external research and development expenses incurred under arrangements with third parties, such as contract research organizations, or CROs and other vendors and contract manufacturing organizations for the production of drug substance and drug product; and

·                           employee-related expenses, including salaries, benefits, travel and share-based compensation expense.

Research and development costs also include costs of acquired product licenses and related technology rights where there is no alternative future use, costs of prototypes used in research and development, consultant fees and amounts paid to collaborative partners.

All research and development costs are charged to operations as incurred in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic, or ASC, 730, Research and Development. We account for non-refundable advance payments for goods and services that will be used in future research and development activities as expenses when the service has been performed or when the goods have been received, rather than when the payment is made.

To date, the large majority of our research and development work has been related to Fovista and Zimura.  We anticipate that our research and development expenses will increase substantially in connection with our ongoing activities, particularly as we continue the development of and seek marketing approval for Fovista, Zimura and, possibly, other product candidates.

We do not currently utilize a formal time allocation system to capture expenses on a project-by-project basis because we record expenses by functional department. Accordingly, we do not allocate expenses to individual projects or product candidates, although we do allocate some portion of our research and development expenses by functional area and by compound, as shown below.

The following table summarizes our research and development expenses for the three months ended March 31, 2015 and 2014:

We expect to spend significant additional funds on our Phase 3 clinical program for Fovista, including costs related to process development and manufacturing scale-up activities for Fovista, our other planned clinical programs, including additional clinical trials to further evaluate the potential benefit of Fovista in wet AMD, when administered in combination with anti-VEGF therapy, and in other ophthalmic diseases and conditions with unmet medical need, a planned clinical trial evaluating Zimura for the treatment of geographic atrophy, a potential clinical trial evaluating Zimura administered in combination with anti-VEGF therapy and Fovista for the treatment of anti-VEGF resistant wet AMD patients who are believed to have complement mediated inflammation, and a very small clinical trial recently begun evaluating Zimura in combination with anti-VEGF therapy for the treatment of polypoidal choroidal vasculopathy, a specific type of wet AMD, in patients who do not respond adequately to treatment with anti-VEGF monotherapy or for whom anti-VEGF monotherapy fails, and for general corporate purposes and working capital. Costs related to our clinical programs could exceed our expectations if we experience delays in our clinical trials, including because of the timing of our patient enrollment, the availability and costs of drug supply for our clinical trials or for other reasons. Our costs will also increase if we increase investigator fees for our clinical trials, if we further expand the scope of our clinical trials and programs, including, for example, by increasing the number of clinical trial sites, or changing the geographic mix of sites at which patients are enrolled, if we increase other corporate or licensing activities or staffing, or if we experience issues with process development and scale-up of manufacturing activities.

Table of Contents

Our current Phase 3 clinical program for Fovista is expected to continue through at least 2017, and substantial expenditures to complete the Phase 3 clinical program will be required after the receipt of initial, top-line data, expected in 2016 for the two clinical trials investigating Fovista in combination with Lucentis, and to fund our other development programs. Moreover, we are at the early stages of formulating our clinical development plan for Zimura. We expect the clinical development of Zimura will continue for at least the next several years. At this time, we cannot reasonably estimate the remaining costs necessary to complete the clinical development of either Fovista or Zimura, complete process development and manufacturing scale-up activities associated with Fovista and Zimura and seek marketing approval for Fovista or Zimura, or the nature, timing or costs of the efforts necessary to complete the development of any other product candidate we may develop.

The successful development of our product candidates is highly uncertain. See “Risk Factors.” This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

·                  the scope, rate of progress and expense of our research and development activities;

·                  the potential benefits of our product candidates over other therapies;

·                  clinical trial results;

·                  the terms and timing of regulatory approvals;

·                  our and our commercialization partner’s ability to market, commercialize and achieve market acceptance for any of our product candidates; and

·                  our ability to successfully file, prosecute, defend and enforce patent claims and other intellectual property rights, together with associated expenses.

A change in the outcome of any of these variables with respect to the development of Fovista, Zimura or any other product candidate we may develop could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if regulatory authorities were to require us to conduct clinical trials beyond those which we currently anticipate will be required for the completion of clinical development of Fovista or any other product candidate or if we experience significant delays in enrollment in any clinical trials, we could be required to expend significant additional financial resources and time on the completion of the clinical development.

See the “Liquidity and Capital Resources” section on page 32 of this Quarterly Report on Form 10-Q/A for more information regarding our current and future financial resources.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs for personnel, including share-based compensation expense, in our executive, legal, finance and business development functions. Other general and administrative expenses include facility costs and professional fees for legal, patent, consulting and accounting services.

We anticipate that our general and administrative expenses will increase in future periods to support increases in our research and development, manufacturing, and commercialization activities and as a result of increased personnel, including management personnel to support our clinical, manufacturing and commercialization activities, expanded infrastructure, increased legal, compliance, accounting and investor and public relations expenses associated with being a public company and increased insurance premiums, among other factors.

Interest Income

Our cash, cash equivalents and marketable securities are invested primarily in U.S. Treasury money market funds and U.S. Treasury securities, which generate a nominal amount of interest income.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and share-based compensation described in greater detail below. We base our estimates on our limited historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

26

Table of Contents

Our significant accounting policies are described in more detail in the notes to our financial statements appearing elsewhere in this Quarterly Report on Form 10-Q/A. Of those policies, we believe that the following accounting policies are the most critical to aid our stockholders in fully understanding and evaluating our financial condition and results of operations.

Accrued Research and Development Expenses

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing quotations and contracts, identifying services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses are related to expenses incurred with respect to CROs, contract manufacturing organizations and other vendors in connection with research and development activities for which we have not yet been invoiced.

We base our expenses related to CROs and contract manufacturing organizations on our estimates of the services received and efforts expended pursuant to quotes and contracts with such vendors that conduct research and development and manufacturing activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the applicable research and development or manufacturing expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. There have been no material changes in estimates for the periods presented.

Revenue Recognition

Collaboration Revenue

Prior to 2014, we had not generated any revenue. In May 2014, we received an up-front payment of $200.0 million in connection with the Novartis Agreement, which has not been recorded as revenue due to certain contingencies associated with the payment. In each of September 2014 and March 2015, we achieved a $50.0 million enrollment-based milestone under the Novartis Agreement, or $100.0 million in the aggregate. We recognized collaboration revenue of approximately $41.7 million during the three months ended March 31, 2015, which primarily related to the $50.0 million milestone we achieved in March 2015. The balance of the milestone payment was recorded as deferred revenue. We use the relative selling price method to allocate arrangement consideration to our performance obligations under the Novartis Agreement. Below is a summary of the components of our collaboration revenue for the three months ended March 2015 and 2014:

We did not recognize any revenue related to our obligation to supply API for Fovista to Novartis during the three months ended March 31, 2015.

In the future, we may generate additional revenues from a combination of product sales and license fees, milestone payments, research and development activity-related payments, payments for manufactured material and royalties in connection with the Novartis Agreement. The terms of this agreement and other potential collaboration or commercialization agreements we may enter into generally contain multiple elements, or deliverables, which may include (i) licenses, or options to obtain licenses, to our technology, (ii) research and development activities to be performed on behalf of the collaborative partner and (iii) in certain cases, services in connection with the manufacturing of pre-clinical, clinical or commercial material. Payments to us under these arrangements typically include one or more of the following: non-refundable, up-front license fees; option exercise fees; funding of research and/or development efforts; milestone payments; payments for manufactured material; and royalties on future product sales.

27

Table of Contents

When evaluating multiple element arrangements, we consider whether the deliverables under the arrangement represent separate units of accounting. This evaluation requires subjective determinations and requires management to make judgments about the individual deliverables and whether such deliverables are separable from the other aspects of the contractual relationship. In determining the units of accounting, management evaluates certain criteria, including whether the deliverables have standalone value, based on the consideration of the relevant facts and circumstances for each arrangement. The consideration received is allocated among the separate units of accounting using the relative selling price method, and the applicable revenue recognition criteria are applied to each of the separate units.

We determine the estimated selling price for deliverables within each agreement using vendor-specific objective evidence (“VSOE”) of selling price, if available, third-party evidence (“TPE”) of selling price if VSOE is not available, or best estimate of selling price (“BESP”) if neither VSOE nor TPE is available. Determining the best estimate of selling price for a deliverable requires significant judgment. We use BESP to estimate the selling price for licenses to our proprietary technology, since we often do not have VSOE or TPE of selling price for these deliverables. In those circumstances where we utilize BESP to determine the estimated selling price of a license to our proprietary technology, we consider market conditions as well as entity-specific factors, including those factors contemplated in negotiating the agreements as well as internally developed models that include assumptions related to the market opportunity, estimated development costs, probability of success and the time needed to commercialize a product candidate pursuant to the license. In validating our BESP, we evaluate whether changes in the key assumptions used to determine the BESP will have a significant effect on the allocation of arrangement consideration among multiple deliverables.

When management believes the license to our intellectual property and products has stand-alone value, we generally recognize revenue attributed to the license upon delivery. When management believes such a license does not have stand-alone value from the other deliverables to be provided in the arrangement, we generally recognize revenue attributed to the license on a straight-line basis over our contractual or estimated performance period, which is typically the term of our research and development obligations. If management cannot reasonably estimate when our performance obligation ends, then revenue is deferred until management can reasonably estimate when the performance obligation ends. The periods over which revenue should be recognized are subject to estimates by management and may change over the course of the research and development agreement. Such a change could have a material impact on the amount of revenue we record in future periods.

At the inception of arrangements that include milestone payments, we evaluate whether each milestone is substantive and at risk to both parties on the basis of the contingent nature of the milestone. This evaluation includes an assessment of whether (a) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, or (2) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve the milestone, (b) the consideration relates solely to past performance, and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. We evaluate factors such as the scientific, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required to achieve the respective milestone and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment.

We aggregate our milestones into three categories: (i) clinical and development milestones, (ii) regulatory milestones, and (iii) commercial milestones. Clinical and development milestones are typically achieved when a product candidate advances into a defined phase of clinical research or completes such phase or when a contractually specified clinical trial enrollment target is attained. Regulatory milestones are typically achieved upon acceptance of the submission of an application for marketing approval of a product candidate or upon approval to market the product candidate by the FDA or other regulatory authorities. For example, a milestone payment may be due to us upon the FDA’s acceptance of an NDA. Commercial milestones are typically achieved when an approved pharmaceutical product reaches certain defined levels of net sales by the licensee, such as when a product first achieves global sales or annual sales of a specified amount.

Revenues from clinical and development and regulatory milestone payments, if the milestones are deemed substantive and the milestone payments are nonrefundable, are recognized upon successful accomplishment of the milestones. With regards to the Novartis Agreement, we have concluded that the clinical and development milestones and certain regulatory milestones are not substantive and that the regulatory approval milestones are substantive. Milestones payments received that are not considered substantive are included in the allocable arrangement consideration and are recognized as revenue in proportion to the relative-selling price allocation established at the inception of the arrangement. Revenues from commercial milestone payments are accounted for as royalties and are recorded as revenue upon achievement of the milestone, assuming all other revenue recognition criteria are met.

Table of Contents

Royalty Purchase Liability

The proceeds from the financing we received under the Novo Agreement have been recorded as a liability on our balance sheet in accordance with ASC 730, Research and Development. Because there is a significant related party relationship between us and Novo A/S, we are treating our obligation to make royalty payments under the Novo Agreement as an implicit obligation to repay the funds advanced by Novo A/S, and thus have recorded the proceeds as a liability on our balance sheet. As we make royalty payments to Novo A/S in accordance with the Novo Agreement, we will reduce the liability balance. At the time that such royalty payments become probable and estimable, and if such amounts exceed the liability balance, we will impute interest accordingly on a prospective basis based on such estimates, which would result in a corresponding increase in the liability balance.

Share-Based Compensation

We account for all share-based compensation payments issued to employees, directors, and consultants using an option pricing model for estimating fair value. Accordingly, share-based compensation expense is measured based on the estimated fair value of the awards on the date of grant, net of forfeitures. We recognize compensation expense for the portion of the award that is ultimately expected to vest over the period during which the recipient renders the required services to us using the straight-line single option method. In accordance with authoritative guidance, we re-measure the fair value of consultant share-based awards as the awards vest, and recognize the resulting value, if any, as expense during the period the related services are rendered.

We apply the fair value recognition provisions of ASC 718, Compensation—Stock Compensation. Determining the amount of share-based compensation to be recorded requires us to develop estimates of the fair value of stock options as of their grant date. We recognize share-based compensation expense ratably over the requisite service period, which in most cases is the vesting period of the award. Calculating the fair value of share-based awards requires that we make highly subjective assumptions.

We use the Black-Scholes option pricing model to value our stock option awards. Use of this valuation methodology requires that we make assumptions as to the volatility of our common stock, the expected term of our stock options, and the risk free interest rate for a period that approximates the expected term of our stock options and the expected dividend yield of our common stock. As a recently public company, we do not have sufficient history to estimate the volatility of our common stock price or the expected life of the options. We calculate expected volatility based on reported data for similar publicly traded companies for which historical information is available and will continue to do so until the historical volatility of our common stock is sufficient to measure expected volatility for future option grants.

We use the simplified method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term of stock option grants to employees as we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. The risk-free interest rate used for each grant is based on the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life. We utilize a dividend yield of zero based on the fact that we have never paid cash dividends and have no current intention to pay cash dividends. The weighted-average assumptions used to estimate grant date fair value of stock options using the Black-Scholes option pricing model were as follows for the three months ended March 31, 2015 and 2014:
