Organization and Summary of Significant Accounting Policies

Description of Business

We are a biotechnology company dedicated to discovering, developing and providing novel therapies that significantly improve the lives of patients with hematologic disorders and cancer. Our pioneering research focuses on signaling pathways that are critical to disease mechanisms.

Our first product approved by the US Food and Drug Administration (FDA) is TAVALISSE® (fostamatinib disodium hexahydrate) tablets, the only approved oral spleen tyrosine kinase (SYK) inhibitor, for the treatment of adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment. The product is also commercially available in Europe and the United Kingdom (UK) (as TAVLESSE), and in Canada, Israel and Japan (as TAVALISSE) for the treatment of chronic ITP in adult patients.

Our second FDA approved product is REZLIDHIA® (olutasidenib) capsules for the treatment of adult patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with a susceptible isocitrate dehydrogenase-1 (IDH1) mutation as detected by an FDA-approved test. We began our commercialization of REZLIDHIA in December 2022. We in-licensed olutasidenib from Forma Therapeutics, Inc. (Forma), with exclusive, worldwide rights for its development, manufacturing and commercialization.

We conducted a Phase 3 clinical trial evaluating fostamatinib for the treatment of warm autoimmune hemolytic anemia (wAIHA) and announced that we did not file a supplemental New Drug Application (sNDA) for this indication considering the top-line data results and guidance received from the FDA. We announced the completion of the FOCUS Phase 3 clinical trial of fostamatinib for the treatment of hospitalized high-risk patients with COVID-19. Fostamatinib is currently being studied in a National Institute of Health (NIH)/National Heart, Lung, and Blood Institute (NHLBI) sponsored Accelerating COVID-19 Therapeutic Inventions and Vaccines Phase 2/3 trial (ACTIV-4 Host Tissue Trial) for the treatment of COVID-19 in hospitalized patients.

Our other clinical programs include our interleukin receptor-associated kinase (IRAK) inhibitor program, and a receptor-interacting serine/threonine-protein kinase (RIPK1) inhibitor program in clinical development with partner Eli Lilly and Company (Lilly). In addition, we have product candidates in clinical development with partners BerGenBio ASA (BerGenBio) and Daiichi Sankyo (Daiichi).

Basis of Presentation

Our accompanying unaudited condensed financial statements have been prepared in accordance with United States generally accepted accounting principles (US GAAP), for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Act of 1933, as amended (Securities Act). Accordingly, they do not include all the information and notes required by US GAAP for complete financial statements. These unaudited condensed financial statements include only normal and recurring adjustments that we believe are necessary to fairly state our financial position and the results of our operations and cash flows. Interim-period results are not necessarily indicative of results of operations or cash flows for a full-year or any subsequent interim period. The balance sheet as of December 31, 2022 has been derived from audited financial statements at that date but does not include all disclosures required by US GAAP for complete financial statements. Because certain disclosures required by US GAAP for complete financial statements are not included herein, these interim unaudited condensed financial statements and the notes accompanying them should be read in conjunction with our audited financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 7, 2023.

Table of Contents 

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from these estimates.

Significant Accounting Policies

Our significant accounting policies are described in “Note 1 – Description of Business and Summary of Significant Accounting Policies” to our “Notes to Financial Statements” contained in “Part II, Item 8, Financial Statements and Supplementary Data” of our Annual Report on Form 10-K for the year ended December 31, 2022. There have been no material changes to these accounting policies.

Liquidity

As of March 31, 2023, we had approximately $58.7 million in cash, cash equivalents and short-term investments. Since inception, we have financed our operations primarily through sales of equity securities, debt financing, contract payments under our collaboration agreements and from product sales.

Based on our current operating plan, we believe that our existing cash, cash equivalents, and short-term investments will be sufficient to fund our expenses and capital expenditure requirements for at least the next 12 months from the date of issuance of this Form 10-Q.

Recently Issued Accounting Standards

Recently issued accounting guidance is either not applicable or did not have, or is not expected to have, a material impact to us.

2.

Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period and the number of additional shares of common stock that would have been outstanding if potentially dilutive securities had been issued. Potentially dilutive securities include stock options, RSUs and shares issuable under our Employee Stock Purchase Plan (Purchase Plan). The dilutive effect of these potentially dilutive securities is reflected in diluted earnings per share using the treasury stock method. Under the treasury stock method, an increase in the fair market value of our common stock can result in a greater dilutive effect from potentially dilutive securities.

The potential shares of common stock that were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive are as follows (in thousands):

Sponsored Research and License Agreements and Government Contract

Sponsored Research and License Agreements

We conduct research and development programs independently and in connection with our corporate collaborators. As of March 31, 2023, we are a party to collaboration agreements with Lilly to develop and commercialize R552, a RIPK1 inhibitor, for the treatment of non-central nervous system (non-CNS) diseases and collaboration aimed at developing additional RIPK1 inhibitors for the treatment of central nervous system (CNS) diseases; with Grifols S.A. (Grifols) to commercialize fostamatinib for human diseases in all indications, including chronic ITP and autoimmune hemolytic anemia (AIHA), in Grifols territory which includes Europe, the UK, Turkey, the Middle East, North Africa and Russia (including Commonwealth of Independent States); with Kissei Pharmaceutical Co., Ltd. (Kissei) to develop and commercialize fostamatinib in Kissei territory which includes Japan, China, Taiwan and the Republic of Korea; with Medison Pharma Trading AG (Medison Canada) and Medison Pharma Ltd. (Medison Israel and, together with Medison Canada, Medison) to commercialize fostamatinib in all indications, including chronic ITP and AIHA, in Medison territory which includes Canada and Israel; and with Knight Therapeutics International SA (Knight) to commercialize fostamatinib in all indications, including chronic ITP and AIHA, in Knight territory which includes Latin America, consisting of Mexico, Central and South America, and the Caribbean (Knight territory).

Further, we are also a party to collaboration agreements, but do not have ongoing performance obligations with BerGenBio for the development and commercialization of AXL receptor tyrosine kinase (AXL) inhibitors in oncology, and with Daiichi to pursue research related to murine double minute 2 (MDM2) inhibitors, a novel class of drug targets called ligases.

Under the above existing agreements that we entered into in the ordinary course of business, we received or may be entitled to receive upfront cash payments, payments contingent upon specified events achieved by such partners and royalties on any net sales of products sold by such partners under the agreements. As of March 31, 2023, total future contingent payments to us under all of above existing agreements, excluding terminated agreements, could exceed $1.3 billion if all potential product candidates achieved all of the payment triggering events under all of our current agreements. Of this amount, $279.5 million relates to the achievement of development events, $263.1 million relates to the achievement of regulatory events and $796.0 million relates to the achievement of certain commercial events. This estimated future contingent amount does not include any estimated royalties that could be due to us if the partners successfully commercialize any of the licensed products. Future events that may trigger payments to us under the agreements are based solely on our partners’ future efforts and achievements of specified development, regulatory and/or commercial events.

Global Exclusive License Agreement with Lilly

We have a global exclusive license agreement and strategic collaboration with Lilly (Lilly Agreement) entered in February 2021, which became effective on March 27, 2021, upon clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, to develop and commercialize R552 for the treatment of non-CNS diseases. In addition, the collaboration is aimed at developing additional RIPK1 inhibitors for the treatment of CNS diseases. Pursuant to the terms of the license agreement, we granted to Lilly exclusive rights to develop and commercialize R552 and related RIPK1 inhibitors in all indications worldwide. The parties’ collaboration is governed through a joint governance committee and appropriate subcommittees.

11

Table of Contents 

We are responsible for 20% of development costs for R552 in the US, Europe, and Japan, up to a specified cap. Lilly is responsible for funding the remainder of all development activities for R552 and other non-CNS disease development candidates. We have the right to opt-out of co-funding the R552 development activities in the US, Europe and Japan at two different specified times. If we exercise our first opt-out right (no later than September 30, 2023), under the Lilly Agreement, we are required to fund our share of the R552 development activities in the US, Europe, and Japan up to a maximum funding commitment of $65.0 million through April 1, 2024. If we decide not to exercise our opt-out rights, we will be required to share in global development costs of up to certain amounts at a specified cap, as provided for in the Lilly Agreement.

We are responsible for performing and funding initial discovery and identification of CNS disease development candidates. Following candidate selection, Lilly will be responsible for performing and funding all future development and commercialization of the CNS disease development candidates.

Under the terms of the Lilly Agreement, we were entitled to receive a non-refundable and non-creditable upfront cash payment amounting to $125.0 million, which we received in April 2021. We are also entitled to additional milestone payments for non-CNS disease products consisting of up to $330.0 million in milestone payments upon the achievement of specified development, regulatory and commercial milestones, and up to $100.0 million in sales milestone payments on a product-by-product basis. In addition, depending on the extent of our co-funding of R552 development activities, we would be entitled to receive tiered royalty payments on net sales of non-CNS disease products at percentages ranging from the mid-single digits to high-teens, subject to certain standard reductions and offsets. We are also eligible to receive milestone payments for CNS disease products consisting of up to $255.0 million in milestone payments upon the achievement of specified development, regulatory and commercial milestones, and up to $150.0 million in sales milestone payments on a product-by-product basis. We would be entitled to receive tiered royalty payments on net sales of CNS disease products up to low-double digits, subject to certain standard reductions and offsets.

We accounted for this agreement under ASC 606 and identified the following distinct performance obligations at inception of the agreement: (a) granting of the license rights over the non-CNS penetrant intellectual property (IP), and (b) granting of the license rights over the CNS penetrant IP which will be delivered to Lilly upon completion of the additional research and development efforts specified in the agreement. We concluded each of these performance obligations is distinct. We based our assessment on the assumption that Lilly can benefit from each of the licenses on its own by developing and commercializing the underlying product using its own resources.

Under the Lilly Agreement, we are required to share 20% of the development costs for R552 in the US, Europe and Japan up to a specified cap. Given our rights to opt-out from the development of R552, we believe at the minimum, we have a commitment to fund the development costs up to $65.0 million as discussed above. We considered this commitment to fund the development costs as a significant financing component of the contract, which we accounted for as a reduction of the upfront fee to derive the transaction price. This financing component was recorded as a liability at its net present value of approximately $57.9 million using a 6.4% discount rate. Interest expense is accreted on such liability over the expected commitment period, adjusted for timing of expected cost share payments. No interest was accreted during the three months ended March 31, 2023 and $0.7 million of interest was accreted during the three months ended March 31, 2022. Through March 31, 2023, Lilly billed us $15.9 million for our share of development costs under this agreement, and the amount was fully paid as of March 31, 2023. As of March 31, 2023 and December 31, 2022, the outstanding financing liability to Lilly was $45.4 million and $46.2 million, respectively, and included within other long-term liabilities, current portion, and other long-term liabilities in the condensed balance sheet.

We allocated the net transaction price of $67.1 million to each performance obligation based on our best estimate of its relative standalone selling price using the adjusted market assessment approach. We concluded that the license rights over the non-CNS penetrant IP represents functional IP that is not expected to change over time, and we have no ongoing or undelivered obligations relative to such IP that Lilly will benefit from the use of such IP on the delivery date. As such, the transaction price allocated to the non-CNS penetrant IP of $60.4 million was recognized as revenue during the first quarter of 2021 upon delivery of the non-CNS penetrant IP to Lilly in March 2021. For the delivery of license rights over the CNS penetrant IP, we were obligated to perform additional research and development efforts before Lilly can accept the license. The allocated transaction price to the CNS penetrant IP of $6.7 million was recognized as revenue from the effective date of the Lilly Agreement through the eventual acceptance by Lilly using the input method. In June 2022, Lilly provided notice of continuance pursuant to the terms of the Lilly Agreement, whereby

12

Table of Contents 

Lilly elected its option to lead the identification and selection of CNS penetrant lead candidate. As such, we recognized the remaining outstanding deferred revenue related to delivery of the CNS penetrant IP in the second quarter of 2022. For the three months ended March 31, 2022, we recognized $0.2 million of revenue associated with the delivery of CNS penetrant IP. No such revenue was recognized in the three months ended March 31, 2023.

The remaining future variable consideration related to future milestone payments as discussed above were fully constrained because we cannot conclude that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur, given the inherent uncertainty of success with these future milestones. For sales-based milestones and royalties, we determined that the license is the predominant item to which the royalties or sales-based milestones relate. Accordingly, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). We will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

Grifols License Agreement

We have an exclusive commercialization license agreement with Grifols entered in January 2019 with exclusive rights to commercialize fostamatinib for human diseases, including chronic ITP and AIHA, and non-exclusive rights to develop fostamatinib in Grifols territory. Under the agreement, we received an upfront payment of $30.0 million, with the potential for $297.5 million in total regulatory and commercial milestones. We are also entitled to receive stepped double-digit royalty payments based on tiered net sales which may reach 30% of net sales. The agreement also required us to continue to conduct our long-term open-label extension study on patients with ITP through European Medicines Agency (EMA) approval of ITP in Europe or until the study ends as well as conduct the Phase 3 trial of fostamatinib in AIHA.

In January 2020, the European Commission (EC) granted a centralized Marketing Authorization (MA) for fostamatinib valid throughout the European Union (EU) and in the UK after the departure of the UK from the EU for the treatment of chronic ITP in adult patients who are refractory to other treatments. With this approval, in February 2020, we received $20.0 million non-refundable payment, composed of a $17.5 million payment due upon Marketing Authorization Application (MAA) approval by the EMA of fostamatinib for the first indication and a $2.5 million creditable advance royalty payment, based on the terms of our collaboration agreement with Grifols. The above milestone payment was allocated to the distinct performance obligations in the collaboration agreement with Grifols.

We accounted for this agreement under ASC 606 and identified the following distinct performance obligations at inception of the agreement: (a) granting of the license, (b) performance of research and regulatory services related to our long-term open-label extension study on patients with ITP, and (c) performance of research services related to our Phase 3 study in AIHA. We allocated the transaction price to the distinct performance obligations in our collaboration agreement based on our best estimate of the relative standalone selling price, and recognized the corresponding revenue in the periods we satisfied the performance obligations. During the three months ended March 31, 2023 and 2022, no revenue and $0.3 million of revenue, respectively, was recognized associated with the remaining performance obligation to perform research services.

The remaining variable consideration related to future regulatory and commercial milestones were fully constrained because we cannot conclude that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, given the inherent uncertainty of success with these future milestones. We are recognizing revenues related to the research and regulatory services throughout the term of the respective clinical programs using the input method. For sales-based milestones and royalties, we determined that the license is the predominant item to which the royalties or sales-based milestones relate. Accordingly, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). We will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

We entered into a Commercial Supply Agreement with Grifols in October 2020 to supply and sell our drug product priced at a certain markup specified in the agreement, in quantities Grifols order from us pursuant to and in accordance with the agreement. Prior to the Commercial Supply Agreement, we had a Drug Product Purchase Agreement with Grifols entered in December 2019. For the three months ended March 31, 2023, we recognized revenue of $1.6 million related to delivery of drug supply to Grifols for its commercialization. No such revenue was recognized during the three months ended March 31, 2022.

We began recognizing royalty revenue from Grifols beginning in the third quarter of 2022. For the three months ended March 31, 2023, we recognized $0.7 million of royalty revenue from Grifols, and such amount was included within contract revenues from collaboration. No such revenue was recognized for the three months ended March 31, 2022.

Kissei License Agreement

We have an exclusive license and supply agreement with Kissei entered in October 2018, to develop and commercialize fostamatinib in all current and potential indications in Kissei’s territory. Kissei is responsible for performing and funding all development activities for fostamatinib in the above-mentioned territories. We received an upfront cash payment of $33.0 million, with the potential for up to an additional $147.0 million in development, regulatory and commercial milestone payments, and will receive mid- to upper twenty percent, tiered, escalated net sales-based payments for the supply of fostamatinib. Under the agreement, we granted Kissei the license rights to fostamatinib in Kissei’s territory and are obligated to supply Kissei with drug product for use in clinical trials and pre-commercialization activities. We are also responsible for the manufacture and supply of fostamatinib for all future development and commercialization activities under the agreement.

We accounted for this agreement under ASC 606 and identified the following distinct performance obligations at inception of the agreement: (a) granting of the license, (b) supply of fostamatinib for clinical use and (c) material right associated with discounted fostamatinib that is supplied for use other than clinical or commercial. In addition, we will provide commercial product supply if the product is approved in the licensed territory. We concluded that each of these performance obligations is distinct. We determined that the upfront fee of $33.0 million represented the transaction price and was allocated to the performance obligations based on our best estimate of the relative standalone selling price and recognized the corresponding revenue in the period we satisfied the performance obligations. As of March 31, 2023 and December 31, 2022, the remaining deferred revenue was related to the material right associated with discounted fostamatinib supply which amounted to $1.4 million.

In April 2022, Kissei announced that an NDA was submitted to Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) for fostamatinib in chronic ITP. With this milestone event, we received $5.0 million non-refundable and non-creditable payment from Kissei pursuant to the terms of our collaboration agreement, and such amount was recognized as revenue in the second quarter of 2022. In December 2022, Kissei announced that Japan’s PMDA approved the NDA for fostamatinib in chronic ITP. With this milestone event, we were entitled to receive $20.0 million non-refundable and non-creditable payment from Kissei pursuant to the terms of our collaboration agreement, which we recognized as revenue in the fourth quarter of 2022. The amount was subsequently collected in January 2023.

The remaining variable consideration related to future development and regulatory milestones was fully constrained because we cannot conclude that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, given the inherent uncertainty of success with these future milestones. For sales-based milestones and tiered, escalated net sales-based payments for the supply of fostamatinib, we determined that the license is the predominant item to which the sales-based milestones relate to. Accordingly, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the allocated costs for the tiered, escalated net sales-based payments has been satisfied (or partially satisfied). We will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur.

Medison Commercial and License Agreements

We have two exclusive commercial and license agreements with Medison entered in October 2019 for the commercialization of fostamatinib for chronic ITP in Medison territory, pursuant to which, we received a $5.0 million upfront payment with respect to the agreement in Canada. We accounted for this agreement under ASC 606 and identified the following combined performance obligations at inception of the agreement: (a) granting of the license and (b) obtaining regulatory approval in Canada of fostamatinib in ITP. We determined that the non-refundable upfront fee of $5.0 million represented the transaction price. However, under the agreement, we have the option to buy back all rights to the product in Canada within six months from obtaining regulatory approval for the treatment of AIHA in Canada. The buyback option precludes us from transferring control of the license to Medison under ASC 606. We believed that the buyback provision, if exercised, will require us to repurchase the license at an amount equal to or more than the upfront $5.0 million. As such, this arrangement was accounted for as a financing arrangement. Interest expense was accreted on such liability over the expected buyback period. We also billed Medison for the delivery of fostamatinib supplies for clinical use which we previously deferred and included within the outstanding financing liability considering the buy-back provision.

The decision to exercise the buyback option is dependent of many factors including management’s cost and benefit assessments and the success of obtaining regulatory approval for the treatment of AIHA in Canada. In June 2022, we reported the top-line results from our Phase 3 trial of fostamatinib in wAIHA which showed that the trial did not demonstrate statistical significance in the primary efficacy endpoint in the overall study population. We also announced in early October 2022 that we will not file an sNDA for wAIHA indication considering the top-line data results and the guidance received from the FDA. With these developments, we assessed our options path forward, including our buyback option right with regards to the Medison license agreement. Based on management’s assessment, the likelihood of exercising the buy-back option right was remote. As such, during the fourth quarter of 2022, we relieved the outstanding financing liability to Medison amounting to $5.7 million and recognized such amount as collaboration revenue in accordance with ASC 606. There was no outstanding financing liability to Medison as of March 31, 2023 and December 31, 2022.

Knight Commercial License and Supply Agreement

We have a commercial license and supply agreements with Knight entered in May 2022 for the commercialization of fostamatinib for approved indications in Knight territory. Pursuant to such commercial license agreement, we received a $2.0 million one-time, non-refundable, and non-creditable upfront payment, with potential for up to an additional $20.0 million in regulatory and sales-based commercial milestone payments, and will receive twenty- to mid-thirty percent, tiered, escalated net-sales based royalty payments for products sold in the Knight territory. We accounted for this agreement under ASC 606 and identified that the upfront payment was a consideration for granting Knight the license to commercialize fostamatinib for approved indication in the Knight territory, and no further material deliverables associated to such upfront payment. As such, we recognized the upfront payment as revenue during the second quarter of 2022. Variable consideration related to future regulatory milestones was fully constrained because we cannot conclude that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur, given the inherent uncertainty of success with these future milestones. For sales-based milestones and royalties, we determined that the license is the predominant item to which the royalties or sales-based milestones relate to. Accordingly, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all the royalty has been allocated has been satisfied (or partially satisfied). We will re-evaluate the transaction price in each reporting period and as uncertain events are resolved or other changes in circumstances occur. We are also responsible for the exclusive manufacture and supply of fostamatinib for all future development and commercialization activities under agreement. 

Government Contract - US Department of Defense’s JPEO-CBRND

In January 2021, we were awarded up to $16.5 million by the US Department of Defense to support our ongoing Phase 3 clinical trial to evaluate the safety and efficacy of fostamatinib for the treatment of hospitalized high-risk patients with COVID-19. The amount of award we will receive from the US Department of Defense is subject to submission of proper documentation as evidence of completion of certain clinical trial events or milestones as specified in the agreement, and approval by the US Department of Defense that such events or milestones have been met. We record government contract revenue in the statement of operations in the period when it is probable that we will receive

the award, which is when we comply with the conditions associated with the award and obtain approval from the US Department of Defense that such conditions have been met. No revenue was recognized during the three months ended March 31, 2023 and 2022. Through March 31, 2023, we received $15.0 million of the awards which we recognized as revenue in the respective periods, with remaining $1.5 million awards available, subject to us meeting certain clinical trial events or milestones and approval by the US Department of Defense as specified in the agreement.

License and Transition Services Agreement with Forma

We have a license and transition services agreement with Forma entered in July 2022, for an exclusive license to develop, manufacture and commercialize olutasidenib, Forma’s proprietary inhibitor of mutated IDH1 (mIDH1), for any uses worldwide, including for the treatment of AML and other malignancies. Forma became a wholly owned subsidiary of Novo Nordisk A/S following the closing of the acquisition of Forma in October 2022. Pursuant to the terms of the license and transition services agreement, we paid Forma an upfront fee of $2.0 million, with the potential to pay up to $67.5 million of additional payments upon achievement of specified development and regulatory milestones and up to $165.5 million of additional payments upon achievement of certain commercial milestones. In addition, subject to the terms and conditions of the license and transition services agreement, Forma would be entitled to tiered royalty payments on net sales of licensed products at percentages ranging from low-teens to mid-thirties, as well as certain portion of our sublicensing revenue, subject to certain standard reductions and offsets.

The transaction was accounted for as an acquisition of asset under ASC 730, Research and Development. In accordance with the guidance, in a transaction accounted for as an asset acquisition, any acquired IPR&D that does not have alternative future use is charged to expense at the acquisition date. At the acquisition date, the acquired license asset was accounted for as IPR&D, and we do not anticipate any economic benefit to be derived from such acquired licensed asset other than the primary indications. As such, we accounted for the upfront fee of $2.0 million paid to Forma as IPR&D and recorded such cost within research and development expenses in the condensed statements of operations in the third quarter of 2022.

Under the accounting guidance, we account for contingent cash payments when it is probable that a liability has been incurred and the amount can be reasonably estimated. We account for milestone payment obligations incurred at development stage and prior to a regulatory approval of an indication associated with the acquired licensed asset as research and development expenses when the event requiring payment of the milestone occurs. Milestone payment obligations incurred upon and after a regulatory approval of an indication associated with the acquired licensed asset, and at the commercial stage, are recorded as intangible asset when the event requiring payment of the milestones occurs. The amount recorded as intangible asset is amortized over the estimated useful life of the acquired licensed asset. Royalty payments related to the acquired licensed asset is recorded as cost of sales when incurred. During the fourth quarter of 2022 prior to the approval of FDA on December 1, 2022, a near-term regulatory milestone was met which entitled Forma to receive a $2.5 million milestone payment. Since such milestone payment obligation was incurred prior to a regulatory approval of an indication associated with the acquired licensed asset, we recorded such amount as research and development expense in the fourth quarter of 2022. On December 1, 2022, the FDA approved REZLIDHIA capsules for the treatment of adult patients with R/R AML with susceptible IDH1 mutations as detected by an FDA-approved test. Following the FDA approval, we launched REZLIDHIA and made first shipments of the product to our customers in December 2022. With this FDA approval and first commercial sale of the product, Forma were entitled to receive a total of $15.0 million milestone payments. Since such milestone payment obligations were incurred upon and after regulatory approval of the product, we recorded such amount as intangible asset on our condensed balance sheet in the fourth quarter of 2022. The $15.0 million milestone payment obligation was outstanding as of December 31, 2022 and included within accounts payable in our condensed balance sheet. Such amount was paid in the first quarter of 2023.

During the three months ended March 31, 2023, we recognized $0.3 million of amortization of intangible asset and $0.2 million of royalty expense related to Forma as discussed above. Such costs were included within cost of sales in our condensed statements of operations. No such expenses were recognized during the three months ended March 31, 2022.

Stock-based compensation expense included within selling, general and administrative in the three months ended March 31, 2022 include an incremental charge of approximately $0.8 million from stock option modifications to extend the exercise period of the stock option grants made to our two former Board of Directors whose terms expired in May 2022.

During the three months ended March 31, 2023, we granted stock options to purchase 2,620,000 shares of common stock with weighted-average grant-date fair value of $1.42 per share, and 952 stock options were exercised. As of March 31, 2023, there were 35,909,499 stock options outstanding, of which, 2,870,000 are outstanding performance-based stock options wherein the achievement of the corresponding corporate-based milestones were not considered probable as of March 31, 2023. Accordingly, none of the $5.3 million grant date fair value for these awards has been recognized as stock-based compensation expense as of March 31, 2023.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. The following table summarizes the weighted-average assumptions relating to options granted pursuant to our Equity Incentive Plans (2018 Equity Incentive Plan and Inducement Plan) for the periods presented:

Employee Stock Purchase Plan

Our Purchase Plan provides for a 24-month offering period comprises four six-month purchase periods with a look-back option. A look-back option is a provision in our Purchase Plan under which eligible employees can purchase shares of our common stock at a price per share equal to the lesser of 85% of the fair market value on the first day of the offering period or 85% of the fair market value on the purchase date. Our Purchase Plan also includes a feature that provides for a new offering period to begin when the fair market value of our common stock on any purchase date during an offering period falls below the fair market value of our common stock on the first day of such offering period. This feature is called a “reset.” Participants are automatically enrolled in the new offering period.

Our previous twenty-four-month offering period under our Purchase Plan ended on June 30, 2022, and a new twenty-four-month offering period started on July 1, 2022. The fair value of awards under our Purchase Plan is estimated on the date of our new offering period using the Black-Scholes option pricing model, which is being amortized over the requisite service periods. As of March 31, 2023, unrecognized stock-based compensation cost related to our Purchase Plan amounted to $0.7 million, which is expected to be recognized over the remaining weighted average period of 0.74 years.

As of March 31, 2023, there were 3,437,633 shares reserved for future issuance under the Purchase Plan.

We maintain a depository relationship with Silicon Valley Bank (SVB). On March 10, 2023, SVB was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. On March 12, 2023, federal regulators announced that the FDIC would complete its resolution of SVB in a manner that fully protects all depositors. On March 27, 2023, First Citizens BancShares, Inc. (FCB) announced that it entered into an agreement with FDIC to purchase all of the asset and liabilities of SVB. Customers of SVB automatically become customers of FCB following the acquisition. To date and as of March 31, 2023, the amount of our cash held on deposit with SVB/FCB was not material with respect our total cash, cash equivalents and short-term investments. All of our cash deposits with SVB/FCB are accessible to us, and we do not anticipate any losses with respect to such funds.

As of March 31, 2023 and December 31, 2022, our cash equivalents and short-term investments had a weighted-average time to maturity of approximately 58 days and 89 days, respectively. Our short-term investments are classified as available-for-sale securities. Accordingly, we have classified certain securities as short-term investments on our condensed balance sheets as they are available for use in the current operations. As of March 31, 2023, we had no investments that had been in a continuous unrealized loss position for more than 12 months. As of March 31, 2023, a total of 16 individual securities had been in an unrealized loss position for 12 months or less, and the losses were determined to be temporary. No significant facts or circumstances have arisen to indicate that there has been any significant deterioration in the creditworthiness of the issuers of the securities held by us. Based on our review of these securities, including the assessment of the duration and severity of the unrealized losses, we have not recognized any credit losses on these securities as of March 31, 2023 and December 31, 2022.
