Summary of Significant Accounting Policies | |
Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Description of Business Xencor, Inc. (we, us, our, or the Company) was incorporated in California in 1997 and reincorporated in Delaware in September 2004. We are a clinical-stage biopharmaceutical company focused on discovering and developing engineered monoclonal bispecific antibody and cytokine therapeutics to treat patients with cancer and autoimmune diseases who have unmet medical needs. We create our product candidates using our proprietary XmAb technology platforms, which focus on the portion of an antibody that interacts with multiple segments of the immune system, referred to as the Fc domain, which is constant and interchangeable among antibodies. Our engineered Fc domains, the XmAb technology, can increase antibody immune inhibition, improve cytotoxicity, extend half-life and most recently are used to create bispecific antibodies and cytokines. Our operations are based in Monrovia, California and San Diego, California. Basis of Presentation The Company’s financial statements as of December 31, 2021, 2020, and 2019 and for the years then ended have been prepared in accordance with accounting principles generally accepted in the United States (U.S.). Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, other comprehensive gain (loss) and the related disclosures. On an ongoing basis, management evaluates its estimates, including estimates related to its accrued clinical trial and manufacturing development expenses, stock-based compensation expense, evaluation of intangible assets, investments, leases and other assets for evidence of impairment, fair value measurements, and contingencies. Significant estimates in these financial statements include estimates made for royalty revenue, accrued research and development expenses, stock-based compensation expenses, intangible assets, incremental borrowing rate for right-of-use asset and lease liability, estimated standalone selling price of performance obligations, estimated time for completing delivery of performance obligations under certain arrangements, the likelihood of recognizing variable consideration, the carrying value of equity instruments without a readily determinable fair value, and recoverability of deferred tax assets. Recent Accounting Pronouncements Pronouncements adopted in 2021 Effective January 1, 2021, the Company adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Effective January 1, 2021, the Company adopted ASU No. 2020-01, which clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investment – Equity Method and Joint Ventures Investments – Equity Securities Effective January 1, 2021, the Company adopted ASU No. 2020-10, Codification Improvements Pronouncements not yet effective There are accounting standards that have been issued by the Financial Accounting Standards Board (FASB) but are not yet effective. The standards are not expected to have a material impact on our results of operations, financial conditions, or cash flows. Revenue Recognition We have, to date, earned revenue from research and development collaborations, which may include research and development services, licenses of our internally developed technologies, licenses of our internally developed drug candidates, or combinations of these. The terms of our license, research and development, and collaboration agreements generally include non-refundable upfront payments, research funding, co-development payments and reimbursements, license fees, and milestone and other contingent payments to us for the achievement of defined collaboration objectives and certain clinical, regulatory and sales-based events, as well as royalties on sales of any commercialized products. The terms of our licensing agreements include non-refundable upfront fees, annual licensing fees, and contractual payment obligations for the achievement of pre-defined preclinical, clinical, regulatory and sales-based events by our partners. The licensing agreements also include royalties on sales of any commercialized products by our partners. We recognize revenue through the five-step process in accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers Deferred Revenue Deferred revenue arises from payments received in advance of the culmination of the earnings process. We have classified deferred revenue for which we stand ready to perform within the next 12 months as a current liability. We recognize deferred revenue as revenue in future periods when the applicable revenue recognition criteria have been met. The total amounts reported as deferred revenue were $37.3 million and $92.6 million at December 31, 2021 and 2020, respectively. Accounts Receivable Accounts receivable primarily consists of royalty and milestone revenues receivable from our license and collaboration agreements, as well as receivables arising from cost-sharing development activities. We did not record allowance for doubtful accounts at December 31, 2021 or 2020, as we expect to collect all receivables within the terms, which are generally between 30 and 60 days. Research and Development Expenses Research and development expenses include costs we incur for our own and for our collaborators’ research and development activities. Research and development costs are expensed as incurred. These costs consist primarily of salaries and benefits, including associated stock-based compensation, laboratory supplies, facility costs, and applicable overhead expenses of personnel directly involved in the research and development of new technology and products, as well as fees paid to other entities that conduct certain research and development activities on our behalf. We estimate preclinical study and clinical trial expenses based on the services performed pursuant to the contracts with research institutions and clinical research organizations that conduct and manage preclinical studies and clinical trials on our behalf based on the actual time and expenses they incurred. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and adjust estimates accordingly. We capitalize acquired research and development technology licenses and third-party contract rights where such assets have an alternative use and amortize the costs over the shorter of the license term or the expected useful life. We review the license arrangements and the amortization period on a regular basis and adjust the carrying value or the amortization period of the licensed rights if there is evidence of a change in the carrying value or useful life of the asset. Cash and Cash Equivalents We consider cash equivalents to be only those investments which are highly liquid, readily convertible to cash and which mature within three months from the date of purchase. Marketable Debt and Equity Securities The Company has an investment policy that includes guidelines on acceptable investment securities, minimum credit quality, maturity parameters, and concentration and diversification. The Company invests its excess cash primarily in marketable debt securities issued by investment grade institutions. The Company considers its marketable debt securities to be available-for-sale and does not intend to sell these securities, and it is not more likely than not the Company will be required to sell the securities before recovery of the amortized cost basis. These assets are carried at fair value and any impairment losses and recoveries related to the underlying issuer’s credit standing are recognized within other income (expense), while non-credit related impairment losses and recoveries are recognized within accumulated other comprehensive income (loss). There were no impairment losses or recoveries recorded for the years ended in December 31, 2021 and 2020, respectively. Accrued interest on marketable debt securities is included in marketable securities’ carrying value. Accrued interest was $0.8 million and $1.4 million at December 31, 2021 and 2020, respectively. Each reporting period, the Company reviews its portfolio of marketable debt securities, using both quantitative and qualitative factors, to determine if each security’s fair value has declined below its amortized cost basis. The Company receives equity securities in connection with certain licensing transactions with its partners. These investments in an equity security are carried at fair value with changes in fair value recognized each period and reported within other income (expense). For equity securities with a readily determinable fair value, the Company remeasures these equity investments at each reporting period until such time that the investment is sold or disposed. If the Company sells an investment, any realized gains or losses on the sale of the securities will be recognized within other income (expense) in the Statement of Comprehensive Income (Loss) in the period of sale. The Company also has investments in equity securities without a readily determinable fair value, where the Company elects the measurement alternative to record at their initial cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Concentrations of Risk Cash, cash equivalents, and marketable debt securities are financial instruments that potentially subject the Company to concentrations of risk. We invest our cash in corporate debt securities and U.S. sponsored agencies with strong credit ratings. We have established guidelines relative to diversification and maturities that are designed to help ensure safety and liquidity. These guidelines are periodically reviewed to take advantage of trends in yields and interest rates. Cash and cash equivalents are maintained at financial institutions, and at times, balances may exceed federally insured limits. We have never experienced any losses related to these balances. Amounts on deposit in excess of federally insured limits at December 31, 2021 and 2020 approximated $143.2 million and $163.3 million, respectively. We have payables with four service providers that represent 64% of our total payables and with one service provider that represented 49% of our total payables at December 31, 2021 and 2020, respectively. We rely on four critical suppliers for the manufacture of our drug product for use in our clinical trials. While we believe that there are alternative vendors available, a change in manufacturing vendors could cause a delay in the availability of drug product and result in a delay of conducting and completing our clinical trials. No other vendor accounted for more than 10% of total payables at December 31, 2021 or 2020. We have receivables with two service providers that represent 84% and 88% of our total receivables at December 31, 2021 and 2020, respectively. The receivables are related to royalty revenues from our licensing and collaboration agreements. No other customer accounted for more than 10% of total receivables at December 31, 2021 or 2020. Fair Value of Financial Instruments Our financial instruments primarily consist of cash and cash equivalents, marketable debt securities, accounts receivable, accounts payable, and accrued expenses. Marketable debt securities and cash equivalents are carried at fair value. The fair value of a financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants. The fair value of the other financial instruments closely approximate their fair value due to their short maturities. The Company accounts for recurring and non-recurring fair value measurements in accordance with FASB ASC 820, Fair Value Measurements and Disclosures Level 1— Level 2— Level 3— The Company measures the fair value of financial assets using the highest level of inputs that are reasonably available as of the measurement date. The assets recorded at fair value are classified within the hierarchy as follows for the periods reported (in thousands): December 31, 2021 Total Fair Value Level 1 Level 2 Level 3 Money Market Funds in Cash and Cash Equivalents $ 123,892 $ 123,892 $ — $ — Corporate Securities 144,418 — 144,418 — Government Securities 309,814 — 309,814 — $ 578,124 $ 123,892 $ 454,232 $ — December 31, 2020 Total Fair Value Level 1 Level 2 Level 3 Money Market Funds in Cash and Cash Equivalents $ 158,937 $ 158,937 $ — $ — Corporate Securities 119,833 — 119,833 — Government Securities 315,353 — 315,353 — $ 594,123 $ 158,937 $ 435,186 $ — Our policy is to record transfers of assets between Level 1 and Level 2 at their fair values as of the end of each reporting period, consistent with the date of the determination of fair value. During the years ended December 31, 2021 and 2020, there were no transfers between Level 1 and Level 2. Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets. Expenditures for repairs and maintenance are charged to expense as incurred, while renewals and improvements are capitalized. Useful lives by asset category are as follows: Computers, software and equipment 3 - 5 years Furniture and fixtures 5 - 7 years Leasehold improvements 5 - 7 years or remaining lease term, whichever is less Patents, Licenses, and Other Intangible Assets The cost of acquiring licenses is capitalized and amortized on the straight-line basis over the shorter of the term of the license or its estimated economic life, ranging from 1 to 18 years. Third-party costs incurred for acquiring patents are capitalized. Capitalized costs are accumulated until the earlier of the period that a patent is issued, or we abandon the patent claims. Cumulative capitalized patent costs are amortized on a straight-line basis from the date of issuance over the shorter of the patent term or the estimated useful economic life of the patent, ranging from 3 to 27 years. Our senior management, with advice from outside patent counsel, assesses three primary criteria to determine if a patent will be capitalized initially: i) technical feasibility, ii) magnitude and scope of new technical function covered by the patent compared to the company’s existing technology and patent portfolio, particularly assessing the value added to our product candidates or licensing business, and iii) legal issues, primarily assessment of patentability and prosecution cost. We review our intellectual property on a regular basis to determine if there are changes in the estimated useful life of issued patents and if any capitalized costs for unissued patents should be abandoned. Capitalized patent costs related to abandoned patent filings are charged off in the period of the decision to abandon. During 2021, 2020, and 2019, we abandoned previously capitalized patent and licensing related charges of $0.9 million, $0.5 million, and $0.2 million, respectively. The carrying amount and accumulated amortization of patents, licenses, and other intangibles is as follows (in thousands): December 31, 2021 2020 Patents, definite life $ 13,231 $ 12,038 Patents, pending issuance 8,821 8,432 Licenses and other amortizable intangible assets 2,474 2,560 Nonamortizable intangible assets (trademarks) 399 399 Total gross carrying amount 24,925 23,429 Accumulated amortization—patents (6,800) (5,791) Accumulated amortization—licenses and other (1,632) (1,661) Total intangible assets, net $ 16,493 $ 15,977 Amortization expense for patents, licenses, and other intangible assets was $1.2 million, $1.1 million, and $0.9 million for the years ended December 31, 2021, 2020, and 2019, respectively. Future amortization expense for patent, licenses, and other intangible assets recorded as of December 31, 2021, and for which amortization has commenced, is as follows: Year ended December 31, (in thousands) 2022 $ 1,073 2023 957 2024 770 2025 680 2026 586 Thereafter 3,207 Total $ 7,273 The above amortization expense forecast is an estimate. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets, and other events. As of December 31, 2021, the Company has $8.8 million of intangible assets which are in-process and have not been placed in service, and accordingly amortization on these assets has not commenced. Long-Lived Assets Management reviews long-lived assets which include fixed assets and amortizable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (or asset group) may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. We did not recognize a loss from impairment for the years ended December 31, 2021, 2020, or 2019. Income Taxes We account for income taxes in accordance with accounting guidance which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. We assess our income tax positions and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where there is greater than 50% likelihood that a tax benefit will be sustained, we have recorded the largest amount of tax benefit that may potentially be realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where there is a 50% or less likelihood that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. We did not have any material uncertain tax positions at December 31, 2021 or 2020. Our policy is to recognize interest and penalties on taxes, if any, as a component of income tax expense. The Tax Cuts and Jobs Act of 2017 (TCJA) enacted on December 22, 2017 included several key provisions impacting the accounting for and reporting of income taxes. The most significant provisions reduced the U.S. corporate statutory tax rate from 35% to 21%, eliminated the corporate Alternative Minimum Tax (AMT) system, and made changes to the carryforward of net operating losses beginning on January 1, 2018. The tax reform provided for a refund of unused AMT carryforwards for years beginning after December 31, 2017. We received an income tax refund during the years ended December 31, 2020 and 2019 of $0.8 million each year related to our federal AMT carryforwards. Stock-Based Compensation We recognize compensation expense using a fair-value-based method for costs related to all share-based payments, including stock options, restricted stock units (RSUs), and shares issued under our Employee Stock Purchase Plan (ESPP). Stock-based compensation cost related to employees and directors is measured at the grant date, based on the fair-value-based measurement of the award using the Black-Scholes method, and is recognized as expense over the requisite service period on a straight-line basis. We account for forfeitures when they occur. We recorded stock-based compensation and expense for stock-based awards to employees, directors, and consultants of approximately $37.0 million, $31.6 million, and $31.9 million for the years ended December 31, 2021, 2020, and 2019, respectively. Net Income (Loss) Per Share Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period without consideration of common stock equivalents. Diluted net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period. Potentially dilutive securities consisting of stock issuable pursuant to outstanding options and restricted stock units (RSUs), and stock issuable pursuant to the 2013 Employee Stock Purchase Plan (ESPP) are not included in the per common share calculation in periods when the inclusion of such shares would have an anti-dilutive effect. Basic and diluted net income (loss) per common share is computed as follows: Basic net income (loss) per common share is computed by dividing the net income or loss by the weighted-average number of common shares outstanding during the period. Potentially dilutive securities were included in the diluted net income per common share calculation for 2021 and 2019. In 2020, we excluded all options and awards from the calculations because we reported net losses in the period, and the inclusion of such shares would have had an antidilutive effect. Year Ended December 31, 2021 2020 2019 (in thousands, except share and per share data) Basic Numerator: Net income (loss) attributable to common stockholders for basic net income (loss) per share $ 82,631 $ (69,333) $ 26,875 Denominator: Weighted-average common shares outstanding 58,379,641 57,212,737 56,531,439 Basic net income (loss) per common share $ 1.42 $ (1.21) $ 0.48 Diluted Numerator: Net income (loss) attributable to common stockholders for diluted net income (loss) per share $ 82,631 $ (69,333) $ 26,875 Denominator: Weighted average number of common shares outstanding used in computing basic net income (loss) per common share 58,379,641 57,212,737 56,531,439 Dilutive effect of employee stock options, RSUs, and ESPP 2,115,814 — 1,936,441 Weighted-average number of common shares outstanding used in computing diluted net income (loss) per common share 60,495,455 57,212,737 58,467,880 Diluted net income (loss) per common share $ 1.37 $ (1.21) $ 0.46 For the year ended December 31, 2021, we excluded 1,196,268 shares of options and RSUs from the calculation of diluted net income per common share because the inclusion of such shares would have had an anti-dilutive effect. For the year ended December 31, 2020, all outstanding potentially dilutive securities were excluded from the calculation as the effect of including such securities would have been anti-dilutive. For the year ended December 31, 2019, we excluded 1,022,623 shares of options and RSUs from the calculation because the inclusion of such shares would have had an anti-dilutive effect. Segment Reporting The Company determines its segment reporting based upon the way the business is organized for making operating decisions and assessing performance. The Company has only one operating segment related to the development of pharmaceutical products . |

Income Taxes | 6. Inc ome Taxes Our effective tax rate differs from the statutory federal income tax rate, primarily as a result of the changes in valuation allowance. There was no provision for taxes for the years ended December 31, 2021 and December 31, 2020. The provision for income taxes for the year ended December 31, 2019 was $0.3 million, which represents the current state alternative minimum tax for the year.

One of the changes was elimination of the AMT tax system for corporations and allowance of an income tax refund for AMT tax credit carryforwards as of December 31, 2017. We have received an income tax refund of $0.8 million and $0.8 million for each year ended December 31, 2020 and 2019 for U.S. AMT credit carryforwards. We have net deferred tax assets relating primarily to net operating loss carryforwards and research and development tax credit carryforwards. Due to the uncertainty surrounding the realization of the benefits of our deferred tax assets in future tax periods, we have placed a valuation allowance against our deferred tax assets at December 31, 2021 and 2020. The Company recognizes valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. The Company’s net deferred income tax asset is not more likely than not to be realized due to the lack of sufficient sources of future taxable income and cumulative losses that have resulted over the years. During the year ended December 31, 2021, the valuation allowance decreased by $12.4 million. The Company’s tax years starting in 2017 through 2020 remain open to potential examination by the U.S. and state taxing authorities due to carryforwards of net operating losses. As of December 31, 2021, we had cumulative net operating loss carryforwards for federal and state income tax purposes of $168.2 million and $161.6 million, respectively, and available tax credit carryforwards of approximately $34.0 million for federal income tax purposes and $17.8 million for state income tax purposes, which can be carried forward to offset future taxable income, if any. The federal net operating loss carryforwards consist of $63.9 million of losses incurred prior to January 1, 2018, which are subject to carryforward limitations and $104.3 million of losses incurred after January 1, 2018, which may be carried forward indefinitely. Our federal net operating loss carryforwards expire starting in 2026, state net operating loss carryforwards expire starting in 2035, and federal tax credit carryforwards began to expire in 2019. A total of $0.5 million in federal tax credits will expire over the next four years if not utilized. Utilization of our net operating loss and tax credit carryforwards are subject to a substantial annual limitation under Section 382 of the Code due to the fact that we have experienced ownership changes. As a result of these changes, certain of our net operating loss and tax credit carryforwards may expire before we can use them. |

Stock-Based Compensation | 7. Stock-Based Compensation Our Board of Directors and the requisite stockholders previously approved the 2010 Equity Incentive Plan (the 2010 Plan). In October 2013, our Board of Directors approved the 2013 Equity Incentive Plan (the 2013 Plan), and in November 2013, our stockholders approved the 2013 Plan. The 2013 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards, and other stock awards. The 2013 Plan became effective as of December 2, 2013, the date of the pricing of the Company’s initial public offering. As of December 2, 2013, we suspended the 2010 Plan, and no additional awards may be granted under the 2010 Plan. Any shares of common stock covered by awards granted under the 2010 Plan that terminate after December 2, 2013 by expiration, forfeiture, cancellation, or other means without the issuance of such shares will be added to the 2013 Plan reserve. As of December 31, 2021, the total number of shares of common stock available for issuance under the 2013 Plan was 13,122,238. Unless otherwise determined by the Board, beginning January 1, 2014, and continuing until the expiration of the 2013 Plan, the total number of shares of common stock available for issuance under the 2013 Plan will automatically increase annually on January 1 by 4% of the total number of issued and outstanding shares of common stock as of December 31 of the immediately preceding year. On January 1, 2021, the total number of shares of common stock available for issuance under the 2013 Plan was increased by 2,314,937 shares, which is included in the number of shares available for issuance above. As of December 31, 2021, a total of 12,400,073 options have been granted under the 2013 Plan. As of December 31, 2021, the Company has awarded 1,124,487 RSUs to certain employees pursuant to the 2013 Plan. Vesting of these awards will be annually over equal installments, either a two or three-year vesting period, and is contingent on continued employment terms. The fair value of these awards is determined based on the intrinsic value of the stock on the date of grant and will be recognized as stock-based compensation expense over the requisite service period. In November 2013, our Board of Directors and stockholders approved the 2013 Employee Stock Purchase Plan (ESPP), which became effective as of December 5, 2013. Under the ESPP our employees may elect to have between 1-15% of their compensation withheld to purchase shares of the Company’s common stock at a discount. The ESPP had an initial two-year term that includes four six-month purchase periods, and employee withholding amounts may be used to purchase Company stock during each six-month purchase period. The initial two-year term ended in December 2015 and pursuant to the provisions of the ESPP, the second two-year term began automatically upon the end of the initial term. The total number of shares that can be purchased with the withholding amounts are based on the lower of 85% of the Company’s common stock price at the initial offering date or 85% of the Company’s stock price at each purchase date. We have reserved a total of 581,286 shares of common stock for issuance under the ESPP. Unless otherwise determined by our Board, beginning on January 1, 2014, and continuing until the expiration of the ESPP, the total number shares of common stock available for issuance under the ESPP will automatically increase annually on January 1 by the lesser of (i) 1% of the total number of issued and outstanding shares of common stock as of December 31 of the immediately preceding year, or (ii) 621,814 shares of common stock. On January 1, 2014, the total number of shares of common stock available for issuance under the ESPP was automatically increased by 313,545 shares, which is included in the number of shares reserved for issuance above.

(3) The total intrinsic value of stock options exercised was $9.2 million, $16.3 million, and $11.5 million for the years ended December 31, 2021, 2020 and 2019 respectively. The stock options outstanding and exercisable by exercise price at December 31, 2021 are as follows: Stock Options Outstanding Stock Options Exercisable Weighted- Average Remaining Weighted- Weighted- Range of Contractual Average Average Exercise Number of Term Exercise Price Number of Exercise Price Prices Shares (in years) Per Share Shares Per Share $4.25 – $10.28 151,488 1.68 $ 4.29 151,488 $ 4.29 $10.52 – $15.78 1,508,709 3.33 $ 13.15 1,507,724 $ 13.15 $15.91 – $23.87 1,777,216 5.52 $ 22.77 1,756,016 $ 22.76 $23.96 – $35.94 2,312,270 7.91 $ 32.08 1,168,530 $ 31.65 $35.99 – $53.99 2,926,646 8.31 $ 40.12 992,672 $ 37.52 8,676,329 6.65 $ 29.11 5,576,430 $ 24.15 We estimated the fair value of employee and non-employee awards using the Black-Scholes valuation model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. Management estimates the probability of non-employee awards being vested based upon an evaluation of the non-employee achieving their specific performance goals. Options are issued at the fair market value of our stock on the date of grant. The fair value of employee stock options was estimated using the following weighted average assumptions for the years ended December 31, 2021, 2020 and 2019: Options 2021 2020 2019 Common stock fair value per share $ 30.65 - 49.47 $ 20.69 - 45.91 $ 29.96 - 44.19 Expected volatility 53.91% - 56.82% 52.93% - 58.95% 60.67% - 61.33% Risk-free interest rate 0.47% - 1.33% 0.29% - 1.71% 1.37% - 2.60% Expected dividend yield — — — Expected term (in years) 6.00 - 7.65 5.23 - 7.65 5.23 - 6.59 ESPP 2021 2020 2019 Expected term (years) 0.5 - 2.0 0.5 - 2.0 0.5 - 2.0 Expected volatility 46.08% - 66.37% 50.77% - 66.37% 50.77% - 71.37% Risk-free interest rate 0.04% - 1.65% 0.09% - 1.65% 1.47% - 2.70% Expected dividend yield — — — The expected term of stock options represents the average period the stock options are expected to remain outstanding. The expected stock price volatility for our stock options for the years ended December 31, 2021, 2020, and 2019 was determined using a blended volatility by examining the historical volatility for industry peer companies and the volatility of our stock from the effective date that our shares were publicly traded on a national stock exchange. We determined the average expected life of stock options based on the anticipated time period between the measurement date and the exercise date by examining the option holders’ past exercise patterns. The risk-free interest rate assumption is based on the U.S. Treasury instruments, for which the term was consistent with the expected term of our stock options. The expected dividend assumption is based on our history and expectation of dividend payouts. We have not paid dividends and did not have any dividend payout at December 31, 2021.

Commitments and Contingencies | 9. Commitments and Contingencies Contingencies From time to time, the Company may be subject to various litigation and related matters arising in the ordinary course of business. The Company does not believe it is currently subject to any material matters where there is at least a reasonable possibility that a material loss may be incurred. We are obligated to make future payments to third parties under in-license agreements, including sublicense fees, 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 balance sheet. We have also entered into agreements with third party vendors which will require us to make future payments upon the delivery of goods and services in future periods. Guarantees In the normal course of business, we indemnify certain employees and other parties, such as collaboration partners and other parties that perform certain work on behalf of, or for the Company or take licenses to our technologies. We have agreed to hold these parties harmless against losses arising from our breach of representations or covenants, intellectual property infringement or other claims made against these parties in performance of their work with us. These agreements typically limit the time within which the party may seek indemnification by us and the amount of the claim. It is not possible to prospectively determine the maximum potential amount of liability under these indemnification agreements since we have not had any prior indemnification claims on which to base the calculation. Further, each potential claim would be based on the unique facts and circumstances of the claim and the particular provisions of each agreement. We are not aware of any potential claims and we did not record a liability as of December 31, 2021 and 2020. |

Collaboration and Licensing Agreements | 10. Collaboration and Licensing Agreements Following is a summary description of the material revenue arrangements, including arrangements that generated revenue in the period ended December 31, 2021, 2020, and 2019. The revenue reported for each agreement has been adjusted to reflect the adoption of ASC 606 for each period presented. Aimmune Therapeutics, Inc. On February 4, 2020, the Company entered into a License, Development and Commercialization Agreement (the Aimmune Agreement) with Aimmune Therapeutics, Inc. (Aimmune) pursuant to which the Company granted Aimmune an exclusive worldwide license to XmAb7195, which was renamed AIMab7195. Under the Aimmune Agreement, Aimmune will be responsible for all further development and commercialization activities for XmAb7195. The Company received an upfront payment of $5.0 million and 156,238 shares of Aimmune common stock with an aggregate value of $4.6 million on the closing date. Under the Aimmune Agreement, the Company is also eligible to receive up to $385.0 million in milestones, which include $22.0 million in development milestones, $53.0 million in regulatory milestones and $310.0 million in sales milestones, and tiered royalties on net sales of approved products from high-single to mid-teen percentage range. Under the Aimmune Agreement, Aimmune received exclusive worldwide rights to manufacture, develop and commercialize XmAb7195. They also received the rights to all data, information and research materials related to the XmAb7195 program. The Company evaluated the Aimmune Agreement under the revenue recognition standard ASC 606 and identified the following performance obligations that it deemed to be distinct at the inception of the contract: ● license to the rights to the XmAb7195 drug candidate; and ● rights to material, data, and information that the Company had accumulated in connection with manufacturing, testing, and conducting clinical trials for the XmAb7195 program and intellectual property filings and information (XmAb7195 data). The Company considered the licenses as functional intellectual property as Aimmune has the right to use XmAb7195 at the time that the Company transfers such rights. The rights to the XmAb7195 data are not considered to be separate from the license to XmAb7195 as Aimmune cannot benefit from the license without the supporting data and documentation. The Company determined the transaction price at inception is $9.6 million which consists of the $5.0 million upfront payment and the 156,238 shares of Aimmune common stock which had a value of $4.6 million on the closing date. The Company determined that the transaction price is to be allocated to the performance obligations. The Aimmune Agreement includes variable consideration for potential future milestones and royalties that are contingent on future success factors for the XmAb7195 program. The Company used the “most likely amount” method to determine the variable consideration. None of the development, regulatory or sales milestones or royalties were included in the transaction price. The Company will re-evaluate the transaction price in each reporting period as uncertain events are resolved or other changes in circumstances occur. The Company determined the transaction price at inception of the Aimmune Agreement and allocated it to the performance obligation, delivery of the XmAb7195 license. The Company completed delivery of its performance obligations in March 2020. The license to XmAb7195 was transferred to Aimmune at inception of the Aimmune Agreement, and the XmAb7195 data were transferred to Aimmune in March 2020. No revenue was recognized for the year ended December 31, 2021; the Company recognized $9.6 million of revenue related to the agreement for the year ended December 31, 2020. There is no deferred revenue as of December 31, 2021 or 2020 related to this agreement. Alexion Pharmaceuticals, Inc.

The Company is eligible to receive contractual milestones for certain commercial achievements, and the Company is also entitled to receive royalties based on a percentage of net sales of such products sold by Alexion, its affiliates, or its sub licensees, which percentage is in the low single digits. Alexion’s royalty obligations continue on a product-by-product and country-by-country basis until the expiration of the last-to-expire valid claim in a licensed patent covering the applicable product in such country. In 2019, Alexion completed certain regulatory submissions for Ultomiris, and the Company received a total of $8.0 million in milestone payments. During 2019, the Company also recorded royalty revenue of $5.0 million in connection with reported net sales of Ultomiris by Alexion. In 2020, the Company received $10.0 million for the achievement of certain sales milestones of Ultomiris in 2020 and also recorded royalty revenue of $16.2 million on net sales.

The total revenue recognized under this arrangement was $22.2 million, $26.2 million, and $13.0 million for the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021, there is a receivable of $10.8 million, and there is no deferred revenue related to this agreement. Amgen Inc. In September 2015, the Company entered into a research and license agreement (the Amgen Agreement) with Amgen Inc. (Amgen) to develop and commercialize bispecific antibody product candidates using the Company’s proprietary XmAb® bispecific Fc technology.

If commercialized, the Company is eligible to receive royalties on net sales that range from the high-single to low-double digit percentages. Astellas has advanced an antibody that was delivered into development, and we received a milestone related to the candidate in 2020. The Company recognized the $13.6 million of revenue in 2019 and recognized $2.5 million related to the milestone in 2020. The $1.4 million allocated to the research activities was recognized as the research services were completed. No revenue was recognized for the year ended December 31, 2021. We recognized $3.5 million and $14.0 million of revenue under this arrangement for the years ended December 31, 2020 and 2019, respectively. There is no deferred revenue as of December 31, 2021.

The Company recognized unrealized gain of $4.5 million related to its equity interest in Astria for the year ended December 31, 2021. There is no deferred revenue as of December 31, 2021 related to this agreement. Bristol-Myers Squibb Company In May 2021, the Company entered into a Technology License Agreement (the BMS Agreement ) with Bristol-Myers Squibb Company (BMS) pursuant to which the Company provided a non-exclusive license to its Xtend technology to extend the half-life of antibodies that specifically bind to SARS-CoV-2. Under the terms of the BMS Agreement, BMS is responsible for all research, development, regulatory and commercial activities for antibodies, and the Company is eligible to receive royalties on net sales of approved products in the low-single digit percentage range.

There is no deferred revenue as of December 31, 2021 related to this agreement. Genentech, Inc., and F. Hoffmann-La Roche Ltd. In February 2019, the Company entered into a collaboration and license agreement (the Genentech Agreement) with Genentech, Inc. and F. Hoffman-La Roche Ltd (collectively, Genentech) for the development and commercialization of novel IL-15 collaboration products (Collaboration Products), including XmAb306, the Company’s IL-15/IL15Rα-Fc candidate. Under the terms of the Genentech Agreement, Genentech received an exclusive worldwide license to XmAb306 and other Collaboration Products, including any new IL-15 programs identified during the joint research collaboration. Genentech and Xencor will jointly collaborate on worldwide development of XmAb306 and potentially other Collaboration Products. The two-year research term expired in March 2021. The Company received a $120.0 million upfront payment and is eligible to receive up to an aggregate of $160.0 million in clinical milestone payments for XmAb306 and up to $180.0 million in clinical milestone payments for each new Collaboration Product. The Company is also eligible to receive 45% share of net profits for sales of XmAb306 and other Collaboration Products, while also sharing in net losses at the same percentage rate. The parties will jointly share in development and commercialization costs for all programs designated as a development program under the Genentech Agreement at the same percentage rate, while Genentech will bear launch costs entirely. The initial 45% profit-cost share percentage is subject to a one-time downward adjustment at the Company’s discretion and convertible to a royalty under certain circumstances. Pursuant to the Genentech Agreement, XmAb306 is designated as a development program and all costs incurred for developing both XmAb306 is being shared with Genentech under the initial cost-sharing percentage. The Company evaluated the Genentech Agreement under the provisions of ASU No. 2014-09, Revenue from Contracts with Customers Collaborative Arrangements The Company identified the following performance obligations under the Genentech Agreement: (i) the license of XmAb306 and (ii) research services during a two-year period, which expired in March 2021, to identify additional IL-15 candidates, each a separate research program and a separate performance obligation. The Company determined that the license and each of the potential research programs are separate performance obligations because they were capable of being distinct in the context of the Genentech Agreement. The license to XmAb306 has standalone functionality as Genentech has exclusive worldwide rights to the program, including the right to sublicense to third parties. Upon the transfer of the license of XmAb306, Genentech could develop and commercialize XmAb306 without further assistance from the Company. The Company determined that the research services for a potential additional IL-15 candidate and research program were separate standalone performance obligations. The Genentech Agreement provided an outline of an integrated research plan for the programs to be conducted by the two companies, and the research activities were separate and distinct from the license to XmAb306. In October 2020, an additional program was declared a Collaboration Program under the Agreement, and the Company completed its performance obligation for that specific research program as the program and licensed rights were transferred to Genentech. The Company determined the standalone selling price of the license to be $114.4 million using the adjusted market assessment approach considering similar collaboration and license agreements and transactions. The standalone selling price for the research activities to be performed during the research term was determined to be $8.5 million using the expected cost approach which was derived from the Company’s experience and information from providing similar research activities to other parties. The Company determined that the transaction price of the Genentech Agreement at inception was $120.0 million consisting of the upfront payment, and allocated the transaction price to each of the separate performance obligations using the relative standalone selling price with $111.7 million allocated to the license to XmAb306, $4.1 million allocated to the additional program and $4.2 million allocated to the research services. The Company recognized the $111.7 million allocated to the license when it satisfied its performance obligation and transferred the license to Genentech in March 2019, and the $8.3 million allocated to the research activities was recognized over a period of time through the end of the research term or the time that a program is delivered to Genentech. The research term expired in the first half of 2021, and the balance in deferred revenue related to the Genentech Agreement was recognized as the Company is no longer required to render services. A total of $2.5 million, $3.5 million, and $2.2 million of revenue related to the research activities was recognized for the years ended December 31, 2021, 2020, and 2019, respectively. For the years ended December 31, 2021, 2020, and 2019, we recognized $2.5 million, $3.5 million, and $113.9 million of income, respectively from the Genentech Agreement. As of December 31, 2021, there is a $2.2 million payable related to cost-sharing development activities during the fourth quarter of 2021. There is no deferred revenue as of December 31, 2021. Gilead Sciences, Inc. In January 2020, the Company entered into a Technology License Agreement (the Gilead Agreement) with Gilead Sciences, Inc. (Gilead), in which the Company provided Gilead an exclusive license to its Cytotoxic Fc and Xtend Fc technologies for an initial identified antibody and options for up to three additional antibodies directed to the same molecular target. Gilead is responsible for all development and commercialization activities for all target candidates. The Company received an upfront payment of $6.0 million and is eligible to receive up to $67.0 million in milestones, which include $10.0 million in development milestones, $27.0 million in regulatory milestones and $30.0 million in sales milestones for each product incorporating the antibodies selected. In addition, the Company is eligible to receive royalties in the low-single digit percentage range on net sales of approved products. In the second quarter of 2020, Gilead exercised options on three additional antibody compounds, and in April 2020, we received a total of $7.5 million in payment of the three options. The total transaction price is $13.5 million which includes the upfront payment of $6.0 million and the option fee payment of $7.5 million which was contractually due with the exercise of the three options by Gilead. The milestone payments are variable consideration to which the Company applied the “most likely amount” method and concluded at inception of the Gilead Agreement it is unlikely that the Company will collect such payments. The milestone payments were not included in the transaction price, and the Company will review this conclusion and update at each reporting period. No revenue was recognized for the year ended December 31, 2021. The Company recognized $13.5 million of revenue related to the Gilead Agreement for the year ended December 31, 2020. There is no deferred revenue as of December 31, 2021 related to this agreement. INmune Bio, Inc. In October 2017, the Company entered into a License Agreement (the INmune Agreement) with INmune. Under the terms of the INmune Agreement, the Company provided INmune with an exclusive license to certain rights to a proprietary protein, XPro1595. In connection with the agreement the Company received 1,585,000 shares of INmune common stock and an option to acquire additional shares of INmune. The Company also received an option to acquire 108,000 shares of INmune common stock with a designee appointed by us serving on the board of directors of INmune. The option had a six-year term from the date of the INmune Agreement and provided the Company the option to purchase up to 10% of the fully diluted outstanding shares of INmune common stock for $10.0 million. The Company initially recorded its equity interest in INmune, including its option to acquire additional INmune shares, at cost pursuant to ASC 323. In June 2021, the Company entered into the First Amendment to License Agreement (the Amended INmune Agreement) and an Option Cancellation Agreement (the Option Agreement) with INmune. The Amended INmune Agreement modified certain diligence provisions in the INmune Agreement with no change in total consideration or performance obligations. The Option Agreement provided for the sale of the option to INmune for the total consideration of $18.3 million which includes $15.0 million in cash and $3.3 million in additional shares of INmune common stock, which represented an additional 192,533 shares of INmune common stock. The Company recorded a realized gain of $18.3 million according to ASC 860, Transfer and Servicing Investments – Equity Securities During the three months ended June 30, 2021, the Company determined that it should no longer record its investment in INmune under the equity method and recorded its investment in INmune pursuant to ASC 321. The Company adjusted the carrying value of this investment by recognizing an unrealized gain of $27.8 million as other income for the three months ended June 30, 2021. In September 2021, the Company exercised its option to purchase 108,000 shares of INmune common stock for $0.8 million. The Company recognized an unrealized gain of $2.0 million, which consists of $1.1 million of fair value of the option and $0.9 million gain on the purchase, as other income for the three months ended September 30, 2021. For the year ended December 31, 2021, the Company recorded $15.1 million of unrealized gain and $18.3 million of realized gain related to its investment in INmune. No revenue was recognized for the year ended December 31, 2021, 2020, or 2019. At the inception of the INmune Agreement in 2017, INmune was a related party as a result of the Company's significant influence with respect to its investment in INmune, as determined under ASC 323. The Company did not have any amounts due to or from INmune at December 31, 2021 or 2020. At June 30, 2021, the Company determined that it no longer has a significant influence in INmune and that INmune is no longer a related party. Janssen Biotech, Inc. Janssen Agreement In November 2020, the Company entered into a Collaboration and License Agreement (the Janssen Agreement) with Janssen Biotech, Inc. (Janssen) pursuant to which Xencor and Janssen will conduct research and development activities to discover novel CD28 bispecific antibodies for the treatment of prostate cancer. Janssen and Xencor will conduct joint research activities for up to a three-year period to discover XmAb bispecific antibodies against CD28 and against an undisclosed prostate tumor-target with Janssen maintaining exclusive worldwide rights to develop and commercialize Licensed Products identified from the research activities. Under the Janssen Agreement, the Company will conduct research activities and apply its bispecific Fc technology to antibodies targeting prostate cancer provided by Janssen. Upon completion of the research activities Janssen will have a candidate selection option to advance an identified candidate for development and commercialization. The activities will be conducted under a research plan agreed to by both parties. Janssen will assume full responsibility for development and commercialization of the CD28 bispecific antibody candidate. Pursuant to the Janssen Agreement, the Company received an upfront payment of $50.0 million and is eligible to receive up to $662.5 million in milestones which include $161.9 million in development milestones, $240.6 million in regulatory milestones and $260.0 million in sales milestones. If commercialized, the Company is eligible to receive royalties on net sales that range from the high-single to low-double digit percentages. Pursuant to the Janssen Agreement, upon development of a bispecific candidate by Janssen through proof of concept, we have the right to opt-in to fund 20% of development costs and to perform 30% of detailing efforts in the U.S. If we exercise this right, we will be eligible to receive tiered royalties in the low-double digit to mid-teen percentage range. We evaluated the Janssen Agreement under ASC 606 and identified the performance obligation under the Agreement to be delivery of CD28 bispecific antibodies to Janssen from the research activities outlined in the research plan. The Company determined that the license to the bispecific antibodies is not a separate performance obligation because it is not capable of being distinct, the license to the antibodies cannot be separated from the underlying antibodies. Janssen will benefit from delivery of the bispecific antibodies upon completion of the research activities. The Company determined that the transaction price of the Janssen Agreement at inception was $50.0 million consisting of the upfront payment. The potential milestones are not included in the transaction price as these are contingent on future events and the Company would not recognize these in revenue until it is not probable that these would not result in significant reversal of revenue amounts in future periods. The candidate selection option payment is substantive and is a separate performance obligation. The Company will re-assess the transaction price at each reporting period and when event outcomes are resolved or changes in circumstances occur. The Company allocated the transaction price to the single performance obligation, delivery of CD28 bispecific antibodies to Janssen. The Company will recognize the $50.0 million transaction price as it satisfies its performance obligation to deliver CD28 bispecific antibodies to Janssen. The Company will recognize revenue related to the performance obligation over the expected period of time to complete and deliver the CD28 bispecific antibodies to Janssen using the expected input method which considers an estimate of the Company’s efforts to complete the research activities outlined in the Janssen Agreement. In November 2021, the Company completed its performance obligations under the research activities and delivered CD28 bispecific antibodies to Janssen. In December 2021, Janssen selected a bispecific CD28 candidate for further development, and we received a milestone of $5.0 million. For the year ended December 31, 2021 the Company recognized as revenue the $50.0 million transaction price in connection with the completion of the research activities and the $5.0 million milestone for selection of an antibody candidate by Janssen. Second Janssen Agreement On October 1, 2021, the Company entered into a second Collaboration and License Agreement (the Second Janssen Agreement) with Janssen pursuant to which the Company granted Janssen an exclusive worldwide license to develop, manufacture, and commercialize plamotamab, the Company’s CD20 x CD3 development candidate, and pursuant to which Xencor and Janssen will conduct research and development activities to discover novel CD28 bispecific antibodies. The parties will conduct joint research activities for up to a two-year period to discover XmAb bispecific antibodies against CD28 and undisclosed B cell tumor-targets with Janssen receiving exclusive worldwide rights, subject to certain Xencor opt-in rights, to develop, manufacture and commercialize pharmaceutical products that contain one or more of such discovered antibodies (CD28 Licensed Antibodies). The Agreement became effective on November 5, 2021. Pursuant to the Second Janssen Agreement, the Company received an upfront payment of $100.0 million and is eligible to receive up to $1,187.5 million in milestones which include $289.4 million in development milestones, $378.1 million in regulatory milestones and $520.0 million in sales milestones. Under the terms of the Stock Purchase Agreement, Johnson & Johnson Innovation, JJDC, Inc. (JJDC), agreed to purchase $25.0 million of newly issued unregistered shares of the Company’s common stock, priced at a 30-day volume-weighted average price of $33.4197 per share as of October 1, 2021. The Company issued JJDC 748,062 shares of its common stock which had a fair market value of $28.9 million when the shares were transferred. The Company will collaborate with Janssen on further clinical development of plamotamab with Janssen and share development costs with Janssen paying 80% and the Company paying 20% of certain development costs. The Company is generally responsible for conducting research activities under the Second Janssen Agreement, and Janssen is generally responsible for all development, manufacturing, and commercialization activities for CD28 Licensed Antibodies that are advanced. Under the Second Janssen Agreement, the Company granted Janssen an exclusive worldwide right to its plamotamab program and the Company will conduct research activities and apply its CD28 bispecific Fc technology to antibodies targeting B-cells. Upon completion of the research activities Janssen will have options to advance up to four identified candidates for development and commercialization. The activities will be conducted under a research plan agreed to by both parties. Janssen will assume full responsibility for development and commercialization of the CD28 bispecific antibody candidate. If commercialized, the Company is eligible to receive royalties on net sales that range from the high-single to low-double digit percentages. The Company evaluated the Second Janssen Agreement under the provisions of ASC 606. We have determined that Janssen is a customer for purposes of the delivery of specific performance obligations under the Second Janssen Agreement and applied the provisions of ASC 606 to the transaction. The Company identified the following performance obligations under the Second Janssen Agreement: (i) the license to the plamotamab program, and (ii) research services during a two-year period to create up to four CD28 bispecific candidates targeting B-cell antigens. The Company determined that the license and the research services are separate performance obligations because they are capable of being distinct and are distinct in the context of the Second Janssen Agreement. The license to plamotamab has standalone functionality as Janssen has exclusive worldwide rights to the program, including the right to sublicense to third parties. Janssen has significant experience and capabilities in developing and commercializing drug candidates similar to plamotamab, and Janssen is capable of performing these activities without the Company’s involvement. Upon the transfer of the license of plamotamab and the related data and materials, Janssen could develop and commercialize plamotamab without further assistance from the Company. The Company determined that the research services for potential CD28 candidates was a separate standalone performance obligation. The Second Janssen Agreement provides an outline of an integrated research plan for the programs to be conducted by the two companies, and the research activities are separate and distinct from the license to plamotamab. The Company determined the standalone selling price of the license to be $58.5 million using the adjusted market assessment approach considering similar collaboration and license agreements and transactions. The standalone selling price for the research services to be performed during the research term was determined to be $37.6 million using the market approach which was derived from the Company’s experience and information from providing similar research services. The Company determined that the transaction price of the Second Janssen Agreement at inception was $96.1 million consisting of the $100.0 million upfront payment reduced by the $3.9 million discount on the proceeds received from the sale of Company common stock to Janssen. The potential milestones are not included in the transaction price as these are contingent on future events and the Company would not recognize these in revenue until it is not probable that these would not result in significant reversal of revenue amounts in future periods. The Company will re-assess the transaction price at each reporting period and when event outcomes are resolved or changes in circumstances occur. The Company allocated the transaction price to each of the separate performance obligations using the relative standalone selling price with $58.5 million allocated to the license to the plamotamab program and $37.6 allocated to the research services. The Company recognized the $58.5 million allocated to the license when it satisfied its performance obligation and transferred the license to Janssen in November 2021. The license was transferred upon the effective date of the Second Janssen Agreement and when the Company subsequently transferred certain data related to the program to Janssen. The $37.6 million allocated to the research services is being recognized over a period of time through the end of the research term that services are rendered as we de |

Summary of Significant Accounting Policies | |
Basis of Presentation | Basis of Presentation The Company’s financial statements as of December 31, 2021, 2020, and 2019 and for the years then ended have been prepared in accordance with accounting principles generally accepted in the United States (U.S.). |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, other comprehensive gain (loss) and the related disclosures. On an ongoing basis, management evaluates its estimates, including estimates related to its accrued clinical trial and manufacturing development expenses, stock-based compensation expense, evaluation of intangible assets, investments, leases and other assets for evidence of impairment, fair value measurements, and contingencies. Significant estimates in these financial statements include estimates made for royalty revenue, accrued research and development expenses, stock-based compensation expenses, intangible assets, incremental borrowing rate for right-of-use asset and lease liability, estimated standalone selling price of performance obligations, estimated time for completing delivery of performance obligations under certain arrangements, the likelihood of recognizing variable consideration, the carrying value of equity instruments without a readily determinable fair value, and recoverability of deferred tax assets. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements Pronouncements adopted in 2021 Effective January 1, 2021, the Company adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Effective January 1, 2021, the Company adopted ASU No. 2020-01, which clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investment – Equity Method and Joint Ventures Investments – Equity Securities Effective January 1, 2021, the Company adopted ASU No. 2020-10, Codification Improvements Pronouncements not yet effective There are accounting standards that have been issued by the Financial Accounting Standards Board (FASB) but are not yet effective. The standards are not expected to have a material impact on our results of operations, financial conditions, or cash flows. |
Revenue Recognition | Revenue Recognition We have, to date, earned revenue from research and development collaborations, which may include research and development services, licenses of our internally developed technologies, licenses of our internally developed drug candidates, or combinations of these. The terms of our license, research and development, and collaboration agreements generally include non-refundable upfront payments, research funding, co-development payments and reimbursements, license fees, and milestone and other contingent payments to us for the achievement of defined collaboration objectives and certain clinical, regulatory and sales-based events, as well as royalties on sales of any commercialized products. The terms of our licensing agreements include non-refundable upfront fees, annual licensing fees, and contractual payment obligations for the achievement of pre-defined preclinical, clinical, regulatory and sales-based events by our partners. The licensing agreements also include royalties on sales of any commercialized products by our partners. We recognize revenue through the five-step process in accordance with Accounting Standards Codification (ASC) 606, Revenue from Contracts with Customers |
Deferred Revenue | Deferred Revenue Deferred revenue arises from payments received in advance of the culmination of the earnings process. We have classified deferred revenue for which we stand ready to perform within the next 12 months as a current liability. We recognize deferred revenue as revenue in future periods when the applicable revenue recognition criteria have been met. The total amounts reported as deferred revenue were $37.3 million and $92.6 million at December 31, 2021 and 2020, respectively. |
Accounts Receivable | Accounts Receivable Accounts receivable primarily consists of royalty and milestone revenues receivable from our license and collaboration agreements, as well as receivables arising from cost-sharing development activities. We did not record allowance for doubtful accounts at December 31, 2021 or 2020, as we expect to collect all receivables within the terms, which are generally between 30 and 60 days. |
Research and Development Expenses | Research and Development Expenses Research and development expenses include costs we incur for our own and for our collaborators’ research and development activities. Research and development costs are expensed as incurred. These costs consist primarily of salaries and benefits, including associated stock-based compensation, laboratory supplies, facility costs, and applicable overhead expenses of personnel directly involved in the research and development of new technology and products, as well as fees paid to other entities that conduct certain research and development activities on our behalf. We estimate preclinical study and clinical trial expenses based on the services performed pursuant to the contracts with research institutions and clinical research organizations that conduct and manage preclinical studies and clinical trials on our behalf based on the actual time and expenses they incurred. Further, we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and adjust estimates accordingly. We capitalize acquired research and development technology licenses and third-party contract rights where such assets have an alternative use and amortize the costs over the shorter of the license term or the expected useful life. We review the license arrangements and the amortization period on a regular basis and adjust the carrying value or the amortization period of the licensed rights if there is evidence of a change in the carrying value or useful life of the asset. |
Cash and Cash Equivalents | Cash and Cash Equivalents We consider cash equivalents to be only those investments which are highly liquid, readily convertible to cash and which mature within three months from the date of purchase. |
Marketable Debt and Equity Securities | Marketable Debt and Equity Securities The Company has an investment policy that includes guidelines on acceptable investment securities, minimum credit quality, maturity parameters, and concentration and diversification. The Company invests its excess cash primarily in marketable debt securities issued by investment grade institutions. The Company considers its marketable debt securities to be available-for-sale and does not intend to sell these securities, and it is not more likely than not the Company will be required to sell the securities before recovery of the amortized cost basis. These assets are carried at fair value and any impairment losses and recoveries related to the underlying issuer’s credit standing are recognized within other income (expense), while non-credit related impairment losses and recoveries are recognized within accumulated other comprehensive income (loss). There were no impairment losses or recoveries recorded for the years ended in December 31, 2021 and 2020, respectively. Accrued interest on marketable debt securities is included in marketable securities’ carrying value. Accrued interest was $0.8 million and $1.4 million at December 31, 2021 and 2020, respectively. Each reporting period, the Company reviews its portfolio of marketable debt securities, using both quantitative and qualitative factors, to determine if each security’s fair value has declined below its amortized cost basis. The Company receives equity securities in connection with certain licensing transactions with its partners. These investments in an equity security are carried at fair value with changes in fair value recognized each period and reported within other income (expense). For equity securities with a readily determinable fair value, the Company remeasures these equity investments at each reporting period until such time that the investment is sold or disposed. If the Company sells an investment, any realized gains or losses on the sale of the securities will be recognized within other income (expense) in the Statement of Comprehensive Income (Loss) in the period of sale. The Company also has investments in equity securities without a readily determinable fair value, where the Company elects the measurement alternative to record at their initial cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. |
Concentrations of Risk | Concentrations of Risk Cash, cash equivalents, and marketable debt securities are financial instruments that potentially subject the Company to concentrations of risk. We invest our cash in corporate debt securities and U.S. sponsored agencies with strong credit ratings. We have established guidelines relative to diversification and maturities that are designed to help ensure safety and liquidity. These guidelines are periodically reviewed to take advantage of trends in yields and interest rates. Cash and cash equivalents are maintained at financial institutions, and at times, balances may exceed federally insured limits. We have never experienced any losses related to these balances. Amounts on deposit in excess of federally insured limits at December 31, 2021 and 2020 approximated $143.2 million and $163.3 million, respectively. We have payables with four service providers that represent 64% of our total payables and with one service provider that represented 49% of our total payables at December 31, 2021 and 2020, respectively. We rely on four critical suppliers for the manufacture of our drug product for use in our clinical trials. While we believe that there are alternative vendors available, a change in manufacturing vendors could cause a delay in the availability of drug product and result in a delay of conducting and completing our clinical trials. No other vendor accounted for more than 10% of total payables at December 31, 2021 or 2020. We have receivables with two service providers that represent 84% and 88% of our total receivables at December 31, 2021 and 2020, respectively. The receivables are related to royalty revenues from our licensing and collaboration agreements. No other customer accounted for more than 10% of total receivables at December 31, 2021 or 2020. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Our financial instruments primarily consist of cash and cash equivalents, marketable debt securities, accounts receivable, accounts payable, and accrued expenses. Marketable debt securities and cash equivalents are carried at fair value. The fair value of a financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants. The fair value of the other financial instruments closely approximate their fair value due to their short maturities. The Company accounts for recurring and non-recurring fair value measurements in accordance with FASB ASC 820, Fair Value Measurements and Disclosures Level 1— Level 2— Level 3— The Company measures the fair value of financial assets using the highest level of inputs that are reasonably available as of the measurement date. The assets recorded at fair value are classified within the hierarchy as follows for the periods reported (in thousands): December 31, 2021 Total Fair Value Level 1 Level 2 Level 3 Money Market Funds in Cash and Cash Equivalents $ 123,892 $ 123,892 $ — $ — Corporate Securities 144,418 — 144,418 — Government Securities 309,814 — 309,814 — $ 578,124 $ 123,892 $ 454,232 $ — December 31, 2020 Total Fair Value Level 1 Level 2 Level 3 Money Market Funds in Cash and Cash Equivalents $ 158,937 $ 158,937 $ — $ — Corporate Securities 119,833 — 119,833 — Government Securities 315,353 — 315,353 — $ 594,123 $ 158,937 $ 435,186 $ — Our policy is to record transfers of assets between Level 1 and Level 2 at their fair values as of the end of each reporting period, consistent with the date of the determination of fair value. During the years ended December 31, 2021 and 2020, there were no transfers between Level 1 and Level 2. |
Property and Equipment | Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets. Expenditures for repairs and maintenance are charged to expense as incurred, while renewals and improvements are capitalized. Useful lives by asset category are as follows: Computers, software and equipment 3 - 5 years Furniture and fixtures 5 - 7 years Leasehold improvements 5 - 7 years or remaining lease term, whichever is less |
Patents, Licenses, and Other Intangible Assets | Patents, Licenses, and Other Intangible Assets The cost of acquiring licenses is capitalized and amortized on the straight-line basis over the shorter of the term of the license or its estimated economic life, ranging from 1 to 18 years. Third-party costs incurred for acquiring patents are capitalized. Capitalized costs are accumulated until the earlier of the period that a patent is issued, or we abandon the patent claims. Cumulative capitalized patent costs are amortized on a straight-line basis from the date of issuance over the shorter of the patent term or the estimated useful economic life of the patent, ranging from 3 to 27 years. Our senior management, with advice from outside patent counsel, assesses three primary criteria to determine if a patent will be capitalized initially: i) technical feasibility, ii) magnitude and scope of new technical function covered by the patent compared to the company’s existing technology and patent portfolio, particularly assessing the value added to our product candidates or licensing business, and iii) legal issues, primarily assessment of patentability and prosecution cost. We review our intellectual property on a regular basis to determine if there are changes in the estimated useful life of issued patents and if any capitalized costs for unissued patents should be abandoned. Capitalized patent costs related to abandoned patent filings are charged off in the period of the decision to abandon. During 2021, 2020, and 2019, we abandoned previously capitalized patent and licensing related charges of $0.9 million, $0.5 million, and $0.2 million, respectively. The carrying amount and accumulated amortization of patents, licenses, and other intangibles is as follows (in thousands): December 31, 2021 2020 Patents, definite life $ 13,231 $ 12,038 Patents, pending issuance 8,821 8,432 Licenses and other amortizable intangible assets 2,474 2,560 Nonamortizable intangible assets (trademarks) 399 399 Total gross carrying amount 24,925 23,429 Accumulated amortization—patents (6,800) (5,791) Accumulated amortization—licenses and other (1,632) (1,661) Total intangible assets, net $ 16,493 $ 15,977 Amortization expense for patents, licenses, and other intangible assets was $1.2 million, $1.1 million, and $0.9 million for the years ended December 31, 2021, 2020, and 2019, respectively. Future amortization expense for patent, licenses, and other intangible assets recorded as of December 31, 2021, and for which amortization has commenced, is as follows: Year ended December 31, (in thousands) 2022 $ 1,073 2023 957 2024 770 2025 680 2026 586 Thereafter 3,207 Total $ 7,273 The above amortization expense forecast is an estimate. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets, and other events. As of December 31, 2021, the Company has $8.8 million of intangible assets which are in-process and have not been placed in service, and accordingly amortization on these assets has not commenced. |
Long-Lived Assets | Long-Lived Assets Management reviews long-lived assets which include fixed assets and amortizable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (or asset group) may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. We did not recognize a loss from impairment for the years ended December 31, 2021, 2020, or 2019. |
Income Taxes | Income Taxes We account for income taxes in accordance with accounting guidance which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. We assess our income tax positions and record tax benefits for all years subject to examination based upon our evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where there is greater than 50% likelihood that a tax benefit will be sustained, we have recorded the largest amount of tax benefit that may potentially be realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where there is a 50% or less likelihood that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. We did not have any material uncertain tax positions at December 31, 2021 or 2020. Our policy is to recognize interest and penalties on taxes, if any, as a component of income tax expense. The Tax Cuts and Jobs Act of 2017 (TCJA) enacted on December 22, 2017 included several key provisions impacting the accounting for and reporting of income taxes. The most significant provisions reduced the U.S. corporate statutory tax rate from 35% to 21%, eliminated the corporate Alternative Minimum Tax (AMT) system, and made changes to the carryforward of net operating losses beginning on January 1, 2018. The tax reform provided for a refund of unused AMT carryforwards for years beginning after December 31, 2017. We received an income tax refund during the years ended December 31, 2020 and 2019 of $0.8 million each year related to our federal AMT carryforwards. |
Stock-Based Compensation | Stock-Based Compensation We recognize compensation expense using a fair-value-based method for costs related to all share-based payments, including stock options, restricted stock units (RSUs), and shares issued under our Employee Stock Purchase Plan (ESPP). Stock-based compensation cost related to employees and directors is measured at the grant date, based on the fair-value-based measurement of the award using the Black-Scholes method, and is recognized as expense over the requisite service period on a straight-line basis. We account for forfeitures when they occur. We recorded stock-based compensation and expense for stock-based awards to employees, directors, and consultants of approximately $37.0 million, $31.6 million, and $31.9 million for the years ended December 31, 2021, 2020, and 2019, respectively. |
Net Income (Loss) Per Share | Net Income (Loss) Per Share Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period without consideration of common stock equivalents. Diluted net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted-average number of common stock equivalents outstanding for the period. Potentially dilutive securities consisting of stock issuable pursuant to outstanding options and restricted stock units (RSUs), and stock issuable pursuant to the 2013 Employee Stock Purchase Plan (ESPP) are not included in the per common share calculation in periods when the inclusion of such shares would have an anti-dilutive effect. Basic and diluted net income (loss) per common share is computed as follows: Basic net income (loss) per common share is computed by dividing the net income or loss by the weighted-average number of common shares outstanding during the period. Potentially dilutive securities were included in the diluted net income per common share calculation for 2021 and 2019. In 2020, we excluded all options and awards from the calculations because we reported net losses in the period, and the inclusion of such shares would have had an antidilutive effect.

For the year ended December 31, 2020, all outstanding potentially dilutive securities were excluded from the calculation as the effect of including such securities would have been anti-dilutive. For the year ended December 31, 2019, we excluded 1,022,623 shares of options and RSUs from the calculation because the inclusion of such shares would have had an anti-dilutive effect. |
