The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this Annual Report. This discussion contains forward-looking statements that reflect our plans, estimates and beliefs and involve risks and uncertainties. Our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those discussed in the section titled "Risk Factors" included under Part I, Item 1A and elsewhere in this Annual Report. See "Special Note Regarding Forward-Looking Statements" in this Annual Report. Overview We are a clinical-stage biopharmaceutical company developing novel therapeutics based on our scientific understanding of key biological pathways underlying cardio-metabolic, liver, oncologic and ophthalmic diseases. These diseases represent leading causes of morbidity and mortality and a significant burden for healthcare systems. Since the commencement of our operations in 2008, we have generated a robust portfolio of product candidates. Our most advanced product candidate, aldafermin, previously known as NGM282, is wholly-owned and entered Phase 2b development for the treatment of NASH in 2019. Five of our other product candidates are in Phase 1 clinical trials and our other programs are in preclinical testing; some of these are subject to our Merck collaboration as described below. InFebruary 2015 , we entered into a five-year research collaboration, product development and license agreement with Merck that allows us to develop multiple product candidates in parallel without bearing substantially greater costs or incurring significantly greater risk compared to developing candidates on our own. ThroughDecember 31, 2019 , Merck had paid us$414.5 million , of which$20.0 million was to license NGM313 and related compounds and$394.5 million was upfront payment and reimbursement of research and development expenses. InMarch 2019 , Merck exercised its option to extend the collaboration throughMarch 16, 2022 and has the right to extend it again throughMarch 16, 2024 . As part of the extension throughMarch 16, 2022 , Merck agreed to continue to fund our research and development efforts at the same levels during the two-year extension period and, in lieu of a$20.0 million extension fee payable to us, Merck will make additional payments totaling up to$20.0 million in support of our research and development activities across 2021 and the first quarter of 2022. InApril 2019 , we completed the IPO of our common stock, in which we issued an aggregate of 7,521,394 shares of common stock, including 854,727 shares of common stock issued pursuant to the over-allotment option granted to the underwriters, at a price of$16.00 per share, before underwriting discounts and commissions. We received approximately$107.8 million in net proceeds, after deducting underwriting discounts, commissions and offering expenses of$4.1 million , of which$2.2 million was paid in 2018. The deferred offering costs were offset against the net proceeds received from the sale of common stock. At the closing of the IPO, all shares of outstanding convertible preferred stock were automatically converted to 47,283,839 shares of common stock. Concurrent with the completion of the IPO, we also issued 4,121,683 shares of common stock to Merck in a private placement at a price of$16.00 per share for proceeds of$65.9 million , which resulted in Merck owning approximately 19.9% of our outstanding shares of common stock. We have incurred net losses in each year since our inception. Our consolidated net losses were$42.8 million ,$0.5 million and$14.2 million for the years endedDecember 31, 2019 , 2018 and 2017, respectively. As ofDecember 31, 2019 , we had an accumulated deficit of$196.1 million , of which$6.1 million was a cumulative effect adjustment to accumulated deficit atJanuary 1, 2019 for the adoption of Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606), and subsequent amendments, under the modified retrospective approach. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and general and administrative costs associated with our operations. Our net losses may fluctuate significantly from quarter to quarter and year to year, depending on the timing of our clinical trials and our expenses on other research and development activities. Since inception, we have funded our operations primarily through the private placement of convertible preferred stock totaling$295.1 million , net proceeds from our IPO of$107.8 million , a private placement of shares of common stock to Merck for$65.9 million , research and development service fees provided by collaboration partners of$324.7 million , upfront license fees paid by collaboration partners of$123.0 million and the license of NGM313 and related compounds to Merck for$20.0 million . We do not have any products approved for sale and 111
-------------------------------------------------------------------------------- do not anticipate generating revenue from product sales for the foreseeable future, if ever. We plan to continue to fund our operations and capital funding needs through public or private equity or debt financings, government or other third-party funding, collaborations, strategic alliances and licensing arrangements or a combination of these. The sale of convertible debt or additional equity could result in additional dilution to our stockholders. Incurring indebtedness would result in debt service obligations and could result in operating and financing covenants that would restrict our operations. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets inthe United States and worldwide resulting from the ongoing COVID-19 pandemic. If we are not able to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible and/or suspend or curtail planned programs. Any of these actions could materially harm our business, results of operations and future prospects. To the extent we obtain additional funding through product collaborations, these arrangements would generally require us to relinquish rights to some of our technologies, product candidates or products, and we may not be able to enter into such agreements on acceptable terms, if at all. We have no manufacturing facilities and all of our manufacturing activities are contracted out to third parties. Additionally, we utilize third-party CROs to carry out certain clinical development activities. Financial Operations Overview
Collaboration Revenue
Our revenue to date has been generated primarily from recognition of license fees and research and development service funding pursuant to our collaboration agreements, the most significant of which is with Merck. Merck is also a significant stockholder and, as such, collaboration revenue from Merck is referred to as related party revenue. We have not generated any revenue from commercial product sales to date. We receive research and development funding pursuant to our Collaboration Agreement and we may also be entitled to receive additional milestone and other contingent payments upon the occurrence of specific events. Due to the nature of this Collaboration Agreement and timing of related revenue recognition, our revenue has fluctuated from period to period in the past and we expect that it will continue to fluctuate in future periods.
The following table summarizes the sources of our collaboration revenue for the

Research and Development Expenses
Research and development efforts relating to our product candidates include manufacturing drug substance, drug product and clinical trial materials, conducting preclinical testing and clinical trials and providing support for these operations.
Our research and development expenses consist of internal and external costs. Our internal costs include employee, consultant, facility and other research and development operating expenses. Our external costs include fees paid to CROs and other service providers in connection with our clinical trials and preclinical studies, third party license fees and costs related to acquiring and manufacturing drug substance, drug product and clinical trial materials. 112 -------------------------------------------------------------------------------- Our clinical development efforts are focused on multiple programs. Our lead product candidate, aldafermin, is the subject of our recently completed Phase 2 and ongoing and planned Phase 2b clinical trials for NASH. We anticipate the majority of our financial resources outside of the Merck collaboration will be dedicated to the development of aldafermin for the foreseeable future. We are also devoting financial resources to the development of NGM395, a product candidate in our GDF15 receptor agonist program, and may devote financial resources to other programs in the event Merck does not elect to license these programs upon completion of a proof-of-concept study or in the event Merck elects to terminate its license to a program. Additionally, if our research and development expenses exceed the funding caps provided in our Collaboration Agreement, which we are anticipating in fiscal year endedDecember 31, 2020 and onwards, we could be required to devote our financial resources toward the development of programs subject to the collaboration. The aldafermin clinical trials under our Phase 2 protocol include our recently completed 24-week expansion cohort of aldafermin (Cohort 4) as a double-blind, placebo-controlled study of once-daily 1 mg aldafermin for the treatment of patients with fibrosis stage F2 or F3 NASH. We have also initiated the ALPINE 2/3 clinical trial, which is a double-blind, placebo-controlled format testing 0.3 mg, 1 mg and 3 mg daily doses of aldafermin for 24 weeks for the treatment of patients with fibrosis stage F2 or F3 NASH, and plan to initiate the ALPINE 4 clinical trial of aldafermin for the treatment of F4 NASH patients with compensated cirrhosis in the first half of 2020. Significant portions of our research and development resources are focused on these clinical trials and other work needed to prepare aldafermin for potential regulatory approval for the treatment of NASH, including manufacturing of clinical trial materials and preparation for Phase 3 testing of aldafermin in NASH. Our NGM313 product candidate has completed the SAD and MAD portions of Phase 1 testing in overweight or obese but otherwise healthy adults, as well as a Phase 1b study in obese insulin resistant subjects with NAFLD. Merck exercised its option to license the NGM313 program in 2018, and all future development expenses will be paid for by Merck unless we elect to exercise our worldwide cost and profit sharing option at the commencement of Phase 3 testing, at which point we would be responsible for a portion of the future development expense. We have initiated Phase 1 clinical trials for NGM120, NGM217 and NGM621, each of which is subject to reimbursement under our Merck collaboration up to the funding caps provided in the Collaboration Agreement. We recently completed a Phase 1 trial assessing the safety, tolerability and pharmacokinetics of NGM120. This clinical trial demonstrated that NGM120 was well tolerated at all doses studied and the pharmacokinetics supported once-monthly dosing. Earlier this year, we initiated a Phase 1a/1b clinical study with NGM120 in cancer patients to explore its potential to treat cancer anorexia-cachexia syndrome and, possibly, tumors. Merck has a one-time option to license NGM120 following completion of a proof-of-concept study in humans. We are also conducting a Phase 1 clinical trial of NGM217 to assess safety and tolerability and to inform dose-range finding for future studies. Thereafter, we plan to commence a Phase 1b/2a proof-of-concept study in diabetic patients to assess the ability of the agent to increase insulin production by the pancreas in the second half of 2020. Merck has a one-time option to license NGM217 following completion of a proof-of-concept study in humans. We initiated a Phase 1 clinical trial of NGM621 in 2019 to assess the safety and tolerability of up to two intravitreal injections of NGM621 in patients with GA, the dry form of AMD. We also plan to initiate a Phase 2 proof-of-concept clinical trial in the second half of 2020. Merck has a one-time option to license NGM621 following completion of a proof-of-concept study in humans. NGM395 and NGM386 comprise our GDF15 receptor agonist program and both were licensed to Merck at the inception of our collaboration. Substantially all of the related research and development expenses for these programs were borne directly by Merck under our Collaboration Agreement. EffectiveMay 31, 2019 , Merck terminated its license to the GDF15 receptor agonist program and we regained full rights to NGM395 and NGM386. Following our assessment of the NGM386 study results, we decided to suspend activities related to NGM386 and focus on advancing NGM395. We initiated a Phase 1 clinical trial to assess safety, tolerability and pharmacokinetics of NGM395 in obese but otherwise healthy adults in the first quarter of 2020. As a result, we will continue to incur research and development expenses with respect to NGM395 in the future. 113 --------------------------------------------------------------------------------
Our research and development expenses related to the development of aldafermin, NGM313, NGM120, NGM217, NGM621 and NGM395 consist primarily of:
• fees paid to our CROs in connection with our clinical trials and other
related clinical trial fees;
• costs related to acquiring and manufacturing drug substance, drug product
and clinical trial materials, including continued testing, such as process
validation and stability, of drug substance and drug product;
• costs related to toxicology testing and other research and preclinical
related studies; • salaries and related overhead expenses, which include stock-based compensation and benefits, for personnel in research and development functions; • fees paid to consultants for research and development activities;
• research and development operating expenses, including facility costs and
depreciation expenses; and • costs related to compliance with regulatory requirements. The process of conducting and supplying materials for preclinical studies and clinical trials necessary to obtain regulatory approval of our product candidates is costly and time consuming. We may never succeed in achieving marketing approval for our product candidates. The success of each product candidate may be affected by numerous factors, including preclinical data, clinical data, competition, manufacturing capability, our sales capabilities, our ability to work effectively with our collaboration partners, regulatory matters, third-party payor matters and commercial viability.
The following is a comparison of research and development expenses for our
programs, including programs that are subject to our Collaboration Agreement
with Merck, for the years ended

research and development programs.
The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs of the efforts that will be necessary to complete the remainder of the development of our product candidates or the period, if any, in which material net cash inflows from these product candidates may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:
• our ability to hire and retain key research and development personnel;
• whether Merck will elect to license or terminate its license to any of our
programs and the timing of such election or termination;
• the scope, rate of progress, results and expense of our ongoing, as well as
any additional, clinical trials and other research and development activities; and • the timing and receipt of any regulatory approvals. 114
-------------------------------------------------------------------------------- A change in the outcome of any of the risks and uncertainties associated with the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation. Other significant costs include legal fees relating to patent and corporate matters, facility costs not otherwise included in research and development expenses and fees for accounting and other consulting services. We anticipate that our general and administrative expenses will increase in the future to support our continued research and development activities. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, lawyers and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with Nasdaq listing rules and relatedSEC requirements and insurance and investor relations costs. In addition, we may incur expenses associated with building a commercial organization in connection with, and prior to, potential future regulatory approval of our product candidates.

Related party revenue was$103.5 million and$108.7 million for the years endedDecember 31, 2019 and 2018, respectively. The decrease of$5.1 million in revenue was primarily due to license revenue of$20.0 million related to NGM313 in 2018, partially offset by an increase of$9.7 million in reimbursable costs related to research personnel and research and development activities and an increase$5.2 million in upfront fee revenue due to the change in revenue recognition methodology associated with the adoption of ASC 606, which requires the recognition of revenue using the cost-based input method as opposed to ratable recognition under ASC 605, which was effectiveJanuary 1, 2019 . Research and Development Expenses. Research and development expenses were$129.3 million and$95.7 million for the years endedDecember 31, 2019 and 2018, respectively. The increase in research and development expenses of$33.5 million was primarily attributable to an increase of$16.6 million in external expenses driven by ongoing clinical trials for our aldafermin program,$11.0 million for the acquisition of clinical trial materials,$7.3 million in personnel-related expenses due to increased headcount and$3.3 million in unallocated research and development expenses related to early research testing. These increases were partially offset by a decrease of$4.7 million in other program external expenses resulting from timing of clinical trial and manufacturing activities. We expect our research and development expenses to increase substantially in 115 -------------------------------------------------------------------------------- connection with our ongoing activities, particularly to the extent that product candidates whose costs are not borne by our collaborator, such as aldafermin and NGM395, advance in clinical development. General and Administrative Expenses. General and administrative expenses were$23.6 million and$17.3 million for the years endedDecember 31, 2019 and 2018, respectively. The increase in general and administrative expenses of$6.3 million was primarily attributable to an increase of$3.4 million in personnel-related expenses, including stock-based compensation due to increased headcount and the implementation of the 2019 Employee Stock Purchase Plan ("2019 ESPP"). Further increasing our general and administrative expenses were$2.0 million for consulting expenses,$1.3 million for legal and accounting expenses and$1.3 million in other miscellaneous general and administrative expenses, including supplies, travel and rent expenses. These increases were offset by$1.7 million in allocated overhead expenses from general and administrative expenses to research and development expenses. We anticipate general and administrative expenses will continue to increase year over year in connection with being a public company which may include increased expenses related to services associated with maintaining compliance with Nasdaq listing rules and relatedSEC requirements, insurance and investor relations costs. Interest Income. Interest income was$6.7 million and$3.6 million for the years endedDecember 31, 2019 and 2018, respectively. The increase in interest income was primarily attributable to an increase in our cash and investments balance subsequent to the completion of our IPO and private placement inApril 2019 .

Total related party revenue was$108.7 million and$77.1 million for the years endedDecember 31, 2018 and 2017, respectively, of which$18.8 million in both periods was related to the partial recognition of the upfront payment from Merck in 2015. The increase of$31.5 million in total revenue was due to an additional$20.0 million of revenue in 2018 recognized from the$20.0 million received from Merck to license NGM313 and related compounds and an increase in both reimbursable personnel related expenses and higher overall external research and development expenses that we incurred in 2018. Research and Development Expenses. Research and development expenses were$95.7 million and$79.7 million for the years endedDecember 31, 2018 and 2017, respectively. The increase in research and development expenses of$16.0 million was primarily attributable to an increase of$9.2 million in external spend mainly driven by manufacturing costs of clinical materials related to our NGM621 program,$5.0 million in hiring- and personnel-related expenses and$3.3 million in unallocated research and development expenses related to early research testing. These increases were offset by a decrease of$1.5 million in external expense due to NGM217 program external expenses for manufacturing costs of clinical materials that occurred in 2017 and timing of clinical trial activities for our other programs. 116
-------------------------------------------------------------------------------- General and Administrative Expenses. General and administrative expenses were$17.3 million and$14.8 million for the years endedDecember 31, 2018 and 2017, respectively. The increase in general and administrative expenses of$2.4 million was primarily due to an increase of$2.8 million in personnel-related expenses,$0.7 million for increased rent expense and increases in professional fees and contract services expenses, including$0.4 million for legal expenses and$0.4 million in audit and tax expenses. These increases were partially offset by$1.9 million in allocated overhead expenses from general and administrative expenses to research and development expenses.
Interest Income. Interest income was
Benefit from Income Taxes. Benefit from income taxes was zero and$1.1 million for the years endedDecember 31, 2018 and 2017, respectively. The benefit from income taxes in 2017 was due to a federal alternative minimum tax credit carryforward that became refundable as a result of the 2017 Tax Cuts and Jobs Act ("2017 Tax Act"). Liquidity and Capital Resources We have incurred losses and negative cash flows from operating activities since our inception. To date, our operations have been financed primarily through the private placement of convertible preferred stock, research and development service fees provided by collaboration partners, primarily Merck, upfront license fees paid by collaboration partners and proceeds from our IPO and concurrent private placement inApril 2019 . As ofDecember 31, 2019 , we had cash and cash equivalents of$245.6 million , short-term marketable securities of$98.9 million , working capital (excluding deferred revenue) of$320.4 million and an accumulated deficit of$196.1 million . We anticipate that we will continue to incur net losses for the foreseeable future as we continue the development of our product candidates, expand our corporate infrastructure to support operations as a public company and conduct pre-commercialization activities. We will require substantial additional capital to achieve our development and commercialization goals for our wholly-owned programs, aldafermin and NGM395, for any future programs that Merck does not opt to license under the Collaboration Agreement and that we choose to develop, for any Merck licensed programs that we opt to co-develop, and for any programs that Merck chooses to license under the Collaboration Agreement and later elects to terminate. Additionally, if our research and development expenses exceed the funding caps provided in our Collaboration Agreement, we could be required to devote our financial resources toward the development of programs subject to the collaboration. If our Merck collaboration were to be terminated, we would require significant additional capital in order to proceed with development and commercialization of our product candidates, or we may enter into additional collaboration or license agreements in order to fund such development and commercialization. We plan to continue to fund our operations and capital funding needs through public or private equity or debt financings, government or other third-party funding, collaborations, strategic alliances and licensing arrangements or a combination of these. The sale of convertible debt or additional equity could result in additional dilution to our stockholders. Incurring indebtedness would result in debt service obligations and could result in operating and financing covenants that would restrict our operations. We cannot assure you that financing will be available in the amounts we need or on terms acceptable to us, if at all. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets inthe United States and worldwide resulting from the ongoing COVID-19 pandemic. To the extent we obtain additional funding through product collaborations, these arrangements would generally require us to relinquish rights to some of our technologies, product candidates or products, and we may not be able to enter into such agreements on acceptable terms, if at all. If we are not able to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible and/or suspend or curtail planned programs. Any of these actions could materially harm our business, results of operations and future prospects. 117 -------------------------------------------------------------------------------- We believe that our existing cash and cash equivalents, along with amounts available to us under our Collaboration Agreement with Merck, will be sufficient to meet our anticipated cash requirements for at least the next 12 months. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially.

Cash Used in Operating Activities
During the year endedDecember 31, 2019 , cash used in operating activities was$41.2 million , which consisted of a net loss of$42.8 million , adjusted for non-cash charges of$19.6 million and cash used through changes in operating assets and liabilities of$17.9 million . The non-cash charges consisted primarily of stock-based compensation expense of$13.0 million and depreciation expense of$7.6 million . The change in operating assets and liabilities was mainly driven by an increase in related party receivable from collaboration of$1.5 million , increase in prepaid expenses and other current assets of$2.0 million , increase in accounts payable of$3.6 million and increase in accrued expenses and other current liabilities of$8.9 million . These increases were offset by a decrease in deferred rent of$2.7 million and deferred revenue of$24.2 million primarily attributed to both the changes in revenue recognition associated with the adoption of ASC 606 and the timing of advance payments from Merck related to the reimbursement of costs associated with research and development activities. During the year endedDecember 31, 2018 , cash used in operating activities was$7.6 million , which consisted of a net loss of$0.5 million , adjusted for non-cash charges of$16.5 million and cash used through changes in operating assets and liabilities of$23.6 million . The non-cash charges consisted primarily of stock-based compensation expense of$10.0 million and depreciation expense of$7.2 million . The change in operating assets and liabilities was primarily due to an increase in related party receivable from collaboration of$3.7 million under our agreement with Merck, increase in prepaid expenses and other current assets of$4.4 million , increase in accounts payable of$3.5 million and increase in accrued expenses and other current liabilities of$4.1 million . These increases were offset by a decrease in deferred rent and deferred revenue of$2.0 million and$21.1 million , respectively. The decrease in deferred revenue is primarily due to the recognition of upfront fees from Merck and the timing of advance payments from Merck related to the reimbursement of costs associated with research and development activities. During the year endedDecember 31, 2017 , cash used in operating activities was$17.4 million , which consisted of a net loss of$14.2 million , adjusted for non-cash charges of$14.5 million and cash used through changes in operating assets and liabilities of$17.7 million . The non-cash charges consisted primarily of stock-based compensation expense of$7.7 million and depreciation expense of$6.4 million . The change in operating assets and liabilities was primarily due to an increase in prepaid expenses and other current assets of$1.1 million primarily resulting from a federal tax receivable generated as a result of the 2017 Tax Act that was signed into law inDecember 2017 and increase in accrued expenses and other current liabilities of$2.6 million resulting from the timing of payments related to our clinical trial expenses and other research and development activities. These increases were offset by a decrease in related party receivable from collaboration of$2.8 million due to payments received from Merck under the Collaboration Agreement, decrease in accounts payable of$4.2 million , decrease in deferred rent of$1.3 million and decrease in deferred revenue of$16.5 million due to the recognition of revenue related to upfront fees from Merck and the timing of advance payments from Merck related to the reimbursement of costs associated with research and development activities. 118
--------------------------------------------------------------------------------
Cash Provided by Investing Activities

Off-Balance Sheet Arrangements We currently have not entered into and do not have any relationships with unconsolidated entities or financial collaborations, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purpose. Contractual Obligations
Our principal obligations consist of the operating lease for our facilities and
non-cancelable purchase commitments with contract manufacturers or service
providers. The following table sets out, as of

(1) Consists of our corporate headquarters lease encompassing approximately
122,000 square feet of office and laboratory space that expires in December
2023.
We enter into agreements in the normal course of business with CROs, contract manufacturers and with vendors for preclinical studies and other services and products for operating purposes that are generally cancelable at any time by us, upon prior written notice, and may or may not include cancellation fees. Given that the amount and timing related to such payments are uncertain, they have not been included in the table above. 119 -------------------------------------------------------------------------------- We are obligated to make future payments to third parties under in-license agreements, including sublicense fees, low single-digit royalties and payments that become due and payable on the achievement of certain development and commercialization milestones. As the amount and timing of sublicense fees and the achievement and timing of these milestones are not probable and estimable, such commitments have not been included on our consolidated balance sheets or in the contractual obligations table above. Critical Accounting Policies and Estimates Our management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance withUnited States generally accepted accounting principles ("U.S. GAAP"). The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as revenue and expenses during the reported periods. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. Our significant accounting policies are described in Note 2 to our consolidated financial statements appearing elsewhere in this Annual Report. We believe that the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations.
Revenue Recognition
On
Prior to the adoption of ASC 606, our revenue from collaboration agreements was recognized when we determined that persuasive evidence of an arrangement exists, services had been rendered, the price was fixed or determinable and collectability was reasonably assured. We would record amounts received prior to satisfying the above revenue recognition criteria as deferred revenue until all applicable revenue recognition criteria were met. Revenue allocated to research activities was generally recognized in the period the services were performed, and revenue allocated to licenses was generally recognized on a straight-line basis over the contractual term. Allocations to non-contingent elements were based on the relative selling price of each element using vendor-specific objective evidence or third-party evidence, where available. In the absence of either of these measures, we used the best estimate of selling price for that deliverable. The most significant change to our policies upon the adoption of ASC 606 is the estimation of an arrangement's total transaction price, which includes unconstrained variable consideration, and the recognition of that transaction price based on a cost-based input method that requires estimates to determine, at each reporting period, the percentage of completion based on the estimated total effort required to complete the project and the total transaction price. Given the differences in revenue recognition policies, the revenue recognized in prior years is not strictly comparable to revenue recorded in the year endingDecember 31, 2019 or in future periods (see Recently Adopted Accounting Pronouncements in the consolidated financial statements). The core principle in ASC 606 requires an entity to recognize revenue upon the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We apply the following five-step revenue recognition model outlined in ASC 606 to adhere to this core principle: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) we satisfy a performance obligation. 120 -------------------------------------------------------------------------------- All of our revenue to date has been generated from our collaboration agreements, primarily our Collaboration Agreement. The terms of these agreements generally require us to provide (i) license options for our compounds, (ii) research and development services and (iii) non-mandatory services in connection with participation in research or steering committees. Payments received under these arrangements may include non-refundable upfront license fees, partial or complete reimbursement of research and development costs, contingent consideration payments based on the achievement of defined collaboration objectives and royalties on sales of commercialized products. In some agreements, the collaboration partner is solely responsible for meeting defined objectives that trigger contingent or royalty payments. Often the partner only pursues such objectives subsequent to exercising an optional license on compounds identified as a result of the research and development services performed. We assess whether the promises in our arrangements, including any options provided to the customer, are considered distinct performance obligations that should be accounted for separately. Judgment is required to determine whether the license to a compound is distinct from research and development services or participation in steering committees, as well as whether options create material rights in the contract. The transaction price in each arrangement is generally comprised of a non-refundable upfront fee and unconstrained variable consideration related to the performance of research and development services. We typically submit a budget for the research and development services to the customer in advance of performing the services. The transaction price is allocated to the identified performance obligations based on the standalone selling price ("SSP") of each distinct performance obligation. Judgment is required to determine SSP. In instances where SSP is not directly observable, such as when a license or service is not sold separately, SSP is determined using information that may include market conditions and other observable inputs. We utilize judgment to assess the nature of our performance obligations to determine whether they are satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress toward completion. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition. Our collaboration agreements may include contingent payments related to specified development and regulatory milestones or contingent payments for royalties based on sales of a commercialized product. Milestones can be achieved for such activities in connection with progress in clinical trials, regulatory filings in various geographical markets and marketing approvals from regulatory authorities. Sales-based royalties are generally related to the volume of annual sales of a commercialized product. At the inception of each agreement that includes such payments, we evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price by using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our or our customer's control, such as those related to regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation based on a relative SSP basis. At the end of each subsequent reporting period, we re-evaluate the probability of achievement of each such milestone and any related constraint and, if necessary, adjust our estimate of the overall transaction price. Pursuant to the guidance in ASC 606, sales-based royalties are not included in the transaction price. Instead, royalties are recognized at the later of when the performance obligation is satisfied or partially satisfied, or when the sale that gives rise to the royalty occurs. 121 --------------------------------------------------------------------------------
As part of the process of preparing these consolidated financial statements, we are required to estimate and accrue expenses, the largest of which are research and development expenses. This process involves:
• Identifying services that have been performed on our behalf by third-party
vendors 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 actual cost;
• estimating and accruing expenses in our consolidated financial statements as
of each balance sheet date based on facts and circumstances known to us at
the time; and
• periodically confirming the accuracy of our estimates with selected service
providers and making adjustments, if necessary.
Examples of estimated research and development expenses that we accrue include:
• fees paid to CROs in connection with preclinical studies and clinical trials;
• fees paid to investigative sites in connection with clinical trials;
• fees paid to CMOs in connection with the production of clinical trial
materials; and • professional service fees for consulting and other services. We base our expense accruals related to clinical trials on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical study milestones. Our service providers generally invoice us monthly in arrears for services performed. 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 we do not identify costs that we have begun to incur or if we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates. All of our clinical trials have been executed with support from CROs and other vendors. We accrue costs for clinical trial activities performed by CROs based upon the estimated amount of work completed on each trial. For clinical trial expenses, the significant factors used in estimating accruals include the number of patients enrolled, the activities to be performed for each patient, the number of active clinical sites and the duration for which the patients will be enrolled in the trial. We monitor patient enrollment levels and related activities to the extent possible through internal reviews, correspondence with CROs and review of contractual terms. We base our estimates on the best information available at the time. To date, we have not experienced significant changes in our estimates of accrued research and development expenses after a reporting period. However, due to the nature of estimates, we cannot assure that we will not make changes to our estimates in the future as we become aware of additional information about the status or conduct of our clinical trials and other research activities.
Stock-Based Compensation
Stock-based compensation expense represents the grant-date fair value of employee stock option granted under our 2008 Equity Incentive Plan (the "2008 Plan") and 2018 Equity Incentive Plan (the "2018 Plan") and rights to acquire stock granted under our 2019 ESPP, recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis, net of estimated forfeitures. OnJanuary 1, 2019 , we adopted ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Non-Employee Share-Based Payment Accounting. Subsequent to the adoption of ASU 2018-07, stock-based compensation expense for non-employee stock-based awards is also measured based on the fair value on grant date with its estimated fair value recorded over the requisite service period of the awards (usually the vesting period) on a straight-line basis, net of estimated forfeitures. 122
-------------------------------------------------------------------------------- We calculate the fair value of stock-based compensation awards using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of subjective assumptions, including stock price volatility, the expected life of stock options, risk free interest rate and the fair value of the underlying common stock on the date of grant. Our key assumptions are:
• Expected Stock Price Volatility: The expected volatility is based on the
historical volatility of the common stock of similar entities within our industry over periods commensurate with our expected term assumption.
• Expected Term of Options: The expected term of options represents the
period of time options are expected to be outstanding. The expected term of
the options granted is derived using the "simplified" method (that is,
estimating the expected term as the mid-point between the vesting date and
the end of the contractual term for each option).
• Risk-free Interest Rate: We base the risk-free interest rate on the
interest rate payable on
grant for a period that is commensurate with the assumed expected option
term.
• Expected Annual Dividends: The estimate for annual dividends is zero because we have not historically paid dividends and do not expect to pay dividends for the foreseeable future. We recorded stock-based compensation expense related to employees, directors and nonemployees of$12.9 million ,$9.9 million and$7.7 million for the years endedDecember 31, 2019 , 2018 and 2017, respectively. As ofDecember 31, 2019 , we had unrecognized stock-based compensation cost related to options granted to employees and directors of$24.1 million , net of forfeitures, which is expected to be recognized as expense over approximately 2.67 years. Prior to the closing of the Company's IPO, the fair value of the common stock underlying our share-based awards was estimated on each grant date by our board of directors. In order to determine the fair value of our common stock underlying option grants, our board of directors considered, among other things, timely valuations of our common stock prepared by an unrelated third-party valuation firm in accordance with the guidance provided by theAmerican Institute of Certified Public Accountants ("AICPA") Practice Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. Given the absence of a public trading market for our common stock historically, our board of directors exercised reasonable judgment and considered a number of objective and subjective factors to determine the best estimate of the fair value of our common stock, including our stage of development; progress of our research and development efforts; the rights, preferences and privileges of our convertible preferred stock relative to those of our common stock; equity market conditions affecting comparable public companies; and the lack of marketability of our common stock. After our IPO, the fair market value of each share of underlying common stock is determined based on the closing price of our common stock as reported by the Nasdaq Global Select Market on the date of grant. JOBS Act Accounting Election We are an "emerging growth company," as defined in the JOBS Act. Under the JOBS Act, emerging growth companies may delay the adoption of new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards would otherwise apply to private companies. The JOBS Act permits an "emerging growth company" such as us to take advantage of an extended transition time to comply with new or revised accounting standards as applicable to public companies. We have elected the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates. We will remain an emerging growth company until the earlier to occur of (1) (a)December 31, 2024 , (b) the last day of the fiscal year in which our annual gross revenue is$1.07 billion or more, or (c) the date on which we are deemed to be a "large-accelerated filer," under the rules of theSEC , which means the market value of our equity 123
