Summary of Significant Accounting Policies | |
Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim financial statements for Xencor, Inc. (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. Certain amounts in the prior period financial statements have been revised to conform to the presentation of the current period financial statements. See “Recent Accounting Pronouncements – Pronouncements Adopted in 2018. ” The financial statements include all adjustments (consisting only of normal recurring adjustments) that the management of the Company believes are necessary for a fair presentation of the periods presented. The preparation of interim financial statements requires the use of management’s estimates and assumptions that affect reported amounts of assets and liabilities at the date of the interim financial statements and the reported revenues and expenditures during the reported periods. These interim financial results are not necessarily indicative of the results expected for the full fiscal year or for any subsequent interim period. The accompanying unaudited interim financial statements and related notes should be read in conjunction with the audited financial statements and notes thereto included in the Company’s 2017 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 28, 2018. Use of Estimates The preparation of interim 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, intangible assets and related amortization. Significant estimates in these interim financial statements include estimates made for accrued research and development expenses, stock-based compensation expenses, intangible assets and related amortization. Intangible Assets The Company maintains definite-lived intangible assets related to certain capitalized costs of acquired licenses and third-party costs incurred in establishing and maintaining its intellectual property rights to its platform technologies and development candidates. These assets are amortized over their useful lives, which are estimated to be the remaining patent life or the contractual term of the license. The straight-line method is used to record amortization expense. The Company assesses its intangible assets for impairment if indicators are present or changes in circumstances suggest that impairment may exist. There were no impairment charges recorded for the three and nine-months ended September 30, 2018 and 2017. The Company capitalizes certain in-process intangible assets that are abandoned when they are no longer pursued. During the nine months ended September 30, 2018 and 2017, the Company abandoned $0.1 million and $0.3 million, respectively, of in-process intangible assets. Marketable 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 securities issued by investment grade institutions. The Company considers its marketable securities to be available-for-sale. These assets are carried at fair value and the unrealized gains and losses are included in accumulated other comprehensive income (loss). Accrued interest on marketable securities is included in marketable securities. If a decline in the value of a marketable security in the Company’s investment portfolio is deemed to be other-than-temporary, the Company writes down the security to its current fair value and recognizes a loss as a charge against income. The Company reviews its portfolio of marketable securities, using both quantitative and qualitative factors, to determine if declines in fair value below cost are other-than-temporary. Recent Accounting Pronouncements Pronouncements Adopted in 2018 Effective January 1, 2018, the Company adopted Accounting Standards Codification Topic 606 (ASC 606), Revenue from Contracts with Customers , using the full retrospective transition method. Under this method, the Company is presenting its financial statements for the years ended December 31, 2016 and 2017 and applicable interim periods within the year ended 2017 as if ASC 606 had been effective for those periods. Under ASC 606 an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. A five-step model is used to achieve the core principle: (1) identify the customer contract, (2) identify the contract’s performance obligations, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations and (5) recognize revenue when or as a performance obligation is satisfied. The Company applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. The new guidance provides that revenue recognition for performance obligations related to delivery of certain goods or services occurs when control over the good or service is transferred to the customer. In addition, the timing of revenue recognition from licensing of our intellectual property that are functional and are distinct performance obligations changed from being recognized over the term of access to our license or technology to being recognized at a point in time. See Note 11 “Prior-Period Financial Statements” for a complete discussion of the impact of adopting the new standard. Effective January 1, 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The adoption of this standard did not have an effect on the Company’s statements of cash flow. Effective January 1, 2018, the Company adopted ASU No. 2017-09, Compensation – Stock Compensation (Topic 718) . The standard applies when a company changes the terms of a stock compensation award granted to an employee. The Company did not have any modifications upon adopting the new standard; therefore, adoption of the new standard had no effect on the Company’s financial statements. Pronouncements Not Yet Effective In February 2016, the FASB issued ASU No. 2016-02 Leases . The new guidance requires lessees to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases not considered short term. The new standard will be effective for reporting periods beginning after December 15, 2018. In July 2018, the FASB issued ASU 2018-11, Lease (Topic 842): Targeted Improvements, which provides an alternative transition method of adoption, permitting the recognition of cumulative-effect adjustment to retained earnings on the date of adoption. We are currently evaluating our leases which includes a review of our lease expenses, which are primarily operating lease arrangements for our facilities in Monrovia and San Diego . We intend to adopt the standard on the effective date but have not yet selected a transition method. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods and services. The standard is effective for fiscal years beginning after December 15, 2018 and interim periods within such fiscal year. The Company does not anticipate that the standard will have a significant impact on its financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosures for transfers between Level 1 and Level 2 of the fair value hierarchy, modifies the level 3 disclosure requirements for non-public entities and requires additional disclosure for Level 3 fair value hierarchy. The amendment is effective for fiscal years beginning after December 15, 2019. The Company does not anticipate that the standard will have a significant impact on its financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendment. The amendment is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. The Company does not anticipate that the standard will have a significant impact on its financial statements. There have been no other material changes to the significant accounting policies previously disclosed in the Company’s 2017 Annual Report on Form 10-K. |

Fair Value of Financial Instruments | |
Fair Value of Financial Instruments | 2. Fair Value of Financial Instruments Financial instruments included in the financial statements include cash equivalents, marketable securities, accounts receivable, accounts payable and accrued expenses. Marketable securities and cash equivalents are carried at fair value. The fair value of the other financial instruments closely approximates their fair value due to their short-term maturities. The Company accounts for recurring and non-recurring fair value measurements in accordance with FASB Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures . ASC 820 defines fair value, establishes a fair value hierarchy for assets and liabilities measured at fair value, and requires expanded disclosure about fair value measurements. The ASC 820 hierarchy ranks the quality of reliable inputs, or assumptions, used in the determination of fair value and requires assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories: Level 1— Fair Value is determined by using unadjusted quoted prices that are available in active markets for identical assets or liabilities. Level 2— Fair Value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets that are not active. Related inputs can also include those used in valuation or other pricing models, such as interest rates and yield curves that can be corroborated by observable market data. Level 3— Fair value is determined by inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgments to be made by the reporting entity –e.g. determining an appropriate discount factor for illiquidity associated with a given security. 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): September 30, 2018 December 31, 2017 Total Total Fair Value Level 1 Level 2 Fair Value Level 1 Level 2 Money Market Funds $ 15,632 $ 15,632 $ — $ 5,175 $ 5,175 $ — Corporate Securities 98,028 — 98,028 123,270 — 123,270 Government Securities 414,805 — 414,805 223,530 — 223,530 $ 528,465 $ 15,632 $ 512,833 $ 351,975 $ 5,175 $ 346,800 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 three and nine months ended September 30, 2018 and 2017, there were no transfers between Level 1 and Level 2. The Company does not have any Level 3 assets or liabilities. |

Net Income (Loss) Per Share | |
Net Income (Loss) Per Share | 3. Net Income (Loss) Per Share We compute net income (loss) per common share 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 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. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants. Potentially dilutive securities consisting of stock issuable under options and our 2013 Employee Stock Purchase Plan (ESPP) are not included in the per common share calculation in periods where there is a net loss where the inclusion of such shares would have had an antidilutive effect. Basic and diluted net income (loss) per common share is computed as follows (in thousands except share and per share data): Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 (As Revised) (As Revised) (in thousands, except share and per share data) Numerator: Net income (loss) attributable to common stockholders $ 3,150 $ (22,652) $ (52,210) $ (45,853) Denominator: Weighted-average common shares outstanding used in computing basic net income (loss) 55,974,080 46,929,498 53,165,774 46,766,562 Weighted-average common shares outstanding used in computing diluted net income (loss) 58,313,002 46,929,498 53,165,774 46,766,562 Basic net income (loss) per common share $ 0.06 $ (0.48) $ (0.98) $ (0.98) Diluted net income (loss) per common share $ 0.05 $ (0.48) $ (0.98) $ (0.98) For the three months ended September 30, 2018 potentially dilutive securities consisting of stock options were included in the diluted net income per common share calculation. For the three months ended September 30, 2017 and nine months ended September 30, 2018 and 2017, all outstanding potentially dilutive securities have been excluded from the calculation of diluted net loss per common share as the effect of including such securities would have been antidilutive.

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 which became effective as of December 3, 2013. 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 September 30, 2018, the total number of shares of common stock available for issuance under the 2013 Plan is 9,618,155 which includes 2,684,456 shares of common stock that were available for issuance under the 2010 Plan as of the effective date of the 2013 Plan. 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 of each year by 4% of the total number of issued and outstanding shares of common stock as of December 31 of the immediate preceding year. Pursuant to approval by our board on January 1, 2018, the total number of shares of common stock available for issuance under the 2013 Plan was increased by 1,880,100 shares. As of September 30, 2018, a total of 6,624,750 options have been issued under the 2013 Plan. 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. 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 of 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. Pursuant to approval by our board, there was no increase in the number of authorized shares in the ESPP in 2018. As of September 30, 2018, we have issued a total of 318,945 shares of common stock under the ESPP. During the nine months ended September 30, 2018, the Company awarded 33,933 Restricted Stock Units (RSUs) to certain employees. Vesting of these awards will be in three equal annual installments 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. Total employee, director and non-employee stock-based compensation expense recognized for the three and nine months ended September 30, 2018 and 2017 are as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 General and administrative $ 2,732 $ 1,422 $ 6,037 $ 4,305 Research and development 3,388 2,183 9,436 5,906 $ 6,120 $ 3,605 $ 15,473 $ 10,211 Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Stock options $ 5,832 $ 3,462 $ 14,723 $ 9,820 ESPP 209 143 562 391 Restricted stock units 79 — 188 — $ 6,120 $ 3,605 $ 15,473 $ 10,211 The following table summarizes option activity under our stock plans and related information: Weighted Weighted Average Average Number of Exercise Remaining Aggregate Shares subject Price Contractual Intrinsic to outstanding (Per Term Value options Share) (in years) (in thousands) Balances at December 31, 2017 5,093,442 $ 15.32 7.62 Options granted 1,679,400 $ 26.63 Options forfeited (107,720) $ 21.66 Options exercised (788,409) $ 8.96 Balance at September 30, 2018 5,876,713 $ 19.29 7.70 $ 115,992 Exercisable 2,857,873 $ 14.76 6.56 $ 69,180 We calculate the intrinsic value as the difference between the exercise price of the options and the closing price of common stock of $38.97 per share as of September 30, 2018.

Commitments 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. |

Collaboration and Licensing Agreements | 9. Collaboration and Licensing Agreements Following is a summary description of the material revenue arrangements, including arrangements that generated revenue in the nine months ended September 30, 2018 and 2017. The revenue reported for each agreement has been adjusted to reflect the adoption of ASC 606 for each period presented. Novartis In June 2016, the Company entered into a Collaboration and License Agreement (the Novartis Agreement) with Novartis Institutes for BioMedical Research, Inc. (Novartis), to develop and commercialize bispecific and other Fc modulated antibody drug candidates using the Company’s proprietary XmAb® technologies and drug candidates. Pursuant to the Novartis Agreement: · The Company granted Novartis certain exclusive rights to research, develop and commercialize XmAb14045 and XmAb13676, two development stage products that incorporate the Company’s bispecific Fc technology; · The Company will apply its bispecific technology in up to four target pair antibodies identified by Novartis (each a Global Discovery Program); and · The Company will provide Novartis with a non-exclusive license to certain of its Fc technologies to apply against up to ten targets identified by Novartis. The Company received a non-refundable upfront payment under the Novartis Agreement of $150 million in July 2016 and is eligible to receive up to $2.4 billion in future development, regulatory and sales milestones in total for all programs that could be developed under the Novartis Agreement. The Company evaluated the Novartis Agreement under the new revenue recognition standard ASC 606 and concluded that Novartis is a customer. The Company identified the following performance obligations that it deemed to be distinct at the inception of the contract: · License to certain rights to Xencor’s XmAb14045 and XmAb13676; · Develop four bispecific drug candidates against four targets identified by Novartis (each a Global discovery program); and · License to Xencor’s Fc technologies for up to 10 targets identified and selected by Novartis. The Company considered the licenses as functional intellectual property as Novartis has the right to access its technology and such technology is functional to Novartis at the time that Xencor provides access. Under the Novartis Agreement, Novartis has substitution rights under each discovery program provided it has not advanced to filing an investigational new drug (IND) application. The Company’s obligation to provide services related to the discovery programs, and Novartis’ right to substitute programs is limited to the five-year period from the date of the Novartis agreement. The Company determined the transaction price at inception is the $150 million upfront payment to be allocated to the performance obligations. The Novartis agreement includes variable consideration for potential future milestones and royalties that were contingent on future success factors for development programs. The Company used the “most likely” 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 Novartis Agreement and allocated it to the various performance obligations using the standalone selling price which is comparable to the relative selling price methodology used in the original accounting treatment for the transaction. The transaction price of $150 million was allocated to the performance obligations as follows: * $27.1 million to certain rights to the XmAb14045 Program; * $31.4 million to certain rights to the XmAb13676 Program; * $20.05 million to each of the four Global Discovery Programs; and * $11.3 million to the Fc licenses. Under ASC 606, revenue is recognized at the time that the Company’s performance obligation for each Global Discovery is completed upon delivery of each discovery program to Novartis. Xencor delivered a discovery program to Novartis in 2017 and recognized $20.05 million of revenue in the period of delivery. In the third quarter of 2018, Xencor delivered a second discovery program to Novartis and is recognizing an additional $20.04 million of revenue. Under ASC 606 the entire amount of revenue allocated to the Fc licenses is being recognized at inception of the Novartis Agreement, the second quarter of 2016. During the three and nine months ended September 30, 2018, we recognized $20.04 million of revenue related to the Novartis Agreement. There were no revenues recognized during the three and nine-month periods ended September 30, 2017. As of September 30, 2018, there is $40.1 million in deferred revenue related to the arrangement. 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. Under the Amgen Agreement, the Company granted an exclusive license to Amgen to develop and commercialize bispecific drug candidates from the Company’s preclinical program that bind the CD38 antigen and the cytotoxic T-cell binding domain CD3 (the CD38 Program). The Company also agreed to apply its bispecific technology to five previously identified Amgen provided targets (each a Discovery Program). The Company received a $45.0 million upfront payment from Amgen and is eligible to receive up to $1.7 billion in future development, regulatory and sales milestones in total for all six programs and is eligible to receive royalties on any global net sales of products. Pursuant to the Amgen Agreement, the Company applied its bispecific technology to five Discovery Programs antibody molecules provided by Amgen that bind Discovery Program Targets and returned the bispecific product candidates to Amgen for further testing, development and commercialization. The initial research term is three years from the date of the Amgen Agreement, but Amgen, at its option, may request an extension of one year. In May 2018, Amgen notified the Company that it was electing to extend the term of the research term for one year. Pursuant to the Agreement, Amgen and the Company will agree upon a detailed plan for services to be provided by the Company during the extended research term. The Company will receive research funding for the additional services provided during the extended research term. Amgen will assume full responsibility for development and commercialization of product candidates under each of the Discovery Programs. The Company evaluated the Amgen Agreement under ASC 606 and determined that it is a customer and that delivery of the CD38 Program and each of the five Discovery Programs represent the performance obligations under the contract. The Company determined the transaction price at inception is the $45 million upfront payment to be allocated to the performance obligations. The Amgen Agreement includes variable consideration for potential future milestones and royalties that were contingent on future success factors for development programs. The Company used the “most likely” method to determine the variable consideration. In the fourth quarter of 2017, the Company received a $10 million development milestone related to the CD38 program and this payment was included in the transaction price as uncertainty associated with it has been resolved. No other 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 and as uncertain events are resolved or other changes in circumstances occur. In allocating the transaction price determined at inception, the Company determined that ASC 606 provides the use of a standalone selling price for the transaction. The transaction price of $55 million was allocated to the performance obligations as follows: * $23.75 million to the CD38 Program and * $6.25 million to each of the five Discovery Programs Under ASC 606, the amount of revenue recognized for the CD38 program is recognized at the inception of the contract when delivery of the CD38 Program and materials was transferred to Amgen. The $10 million milestone revenue was recognized in the period that the uncertainty regarding the event is resolved, i.e., when the milestone event occurred. The Company completed performance obligations for the five discovery programs in 2016 when all five of the Discovery Programs were delivered to Amgen. Pursuant to ASC 606 the Company recognized $31.25 million of revenue for delivery of the five discovery programs in 2016. In the third quarter of 2018, the Company and Amgen agreed upon additional scope of work to be performed by Xencor; however, no work has been performed to date. The Company did not recognize any revenue for each of the three and nine months ended September 30, 2018 and 2017. There is no deferred revenue as of September 30, 2018 related to this arrangement. Alexion Pharmaceuticals, Inc. In January 2013, we entered into an option and license agreement with Alexion Pharmaceuticals, Inc. (Alexion). Under the terms of the agreement, we granted to Alexion an exclusive research license, with limited sublicensing rights, to make and use our Xtend technology to evaluate and advance compounds against six different target programs during a five-year research term under the agreement, up to completion of the first multi-dose human clinical trial for each target compound. Under the agreement, we received an upfront payment of $3.0 million and annual maintenance fees totaling $2 million during the research term. We are also eligible to receive development, regulatory and commercial milestones. If licensed products are successfully commercialized, we are 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 will 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 the third quarter of 2014, Alexion achieved a Phase 1 milestone with ALXN1210, a compound that incorporates our Xtend technology. In the fourth quarter of 2015, Alexion exercised its option to take an exclusive commercial license to ALXN1210 and achieved a Phase 2 clinical development milestone for ALXN1210. In December 2016, Alexion achieved a Phase 3 clinical development milestone for ALXN1210. In the third quarter of 2018, Alexion completed certain regulatory submission filings for ALXN1210 and the Company received $9 million in milestone payments. The Company determined Alexion to be a customer and the license of the Company’s Xtend intellectual property is functional intellectual property, distinct and is the only performance obligation under the agreement. The upfront fee, the net present value of the annual maintenance fees, the option exercise fee and milestone payments of $17.5 million already received represent the total transaction price at inception. The option exercise fee does not provide a discount on future services and does not grant a material right. Under ASC 606 the upfront payment and the present value of the annual licensing fees are recognized at inception of the agreement when Alexion was provided access to the technology. During the three and nine months ended September 30, 2018 the Company recognized $9 million of milestone revenues. For the same periods in 2017, no revenue was recognized under this arrangement. There is no deferred revenue related to this arrangement at September 30, 2018. CSL Limited In February 2009, we entered into a research license and commercialization agreement with CSL Limited (CSL). Under the agreement, we provided CSL with a research license to our Fc Cytotoxic technology and options to non-exclusive commercial licenses. CSL elected to exercise one commercial license for a compound, CSL362. In 2013 CSL sublicensed CSL362 (now called talacotuzumab) to Janssen Biotech Inc. (Janssen Biotech). In March 2017, CSL, through its sub-licensee, Janssen Biotech, initiated a Phase 3 clinical trial for CSL362 and we received a milestone payment of $3.5 million. During the three and nine months ended September 30, 2018, there were no revenues recognized. During the three and nine months ended September 30, 2017 we recognized zero and $3.5 million of revenue, respectively, under the arrangement. There is no deferred revenue related to this arrangement at September 30, 2018. |

Income Taxes | 10. Income taxes There is no provision for income taxes for the three and nine-month periods ended September 30, 2018. No income tax benefit can be recognized in these periods due to uncertainty about the Company’s ability to generate taxable income in future periods. The provision for income taxes for the three and nine months ended September 30, 2017 represents the interim period tax allocation of the federal and state alternative minimum tax based on the Company’s projected year-end effective income tax rates which cannot be offset by the Company’s net operating loss carryforwards. The Company has a federal income tax receivable of $1.5 million at September 30, 2018 related to refundable alternative minimum tax credits. As of September 30, 2018, the Company’s deferred income tax assets, consisting primarily of net operating loss and tax credit carryforwards, have been fully offset by a valuation allowance. |

Prior-Period Financial Statements | 11. Prior-Period Financial Statements The Company adopted ASC 606 on January 1, 2018 using the full retrospective method and as a result the Company has revised its comparative financial statements for the prior period as if ASC 606 had been in effect for that period. The most significant changes to revenue recognition under ASC 606 relate to the timing of revenue recognized for arrangements that include licensing of our technologies. Under ASC 606 revenue related to licensing of access to our technologies is recognized at inception of the agreement, generally the effective date of the agreement. For existing licensing arrangements, the effect of ASC 606 is to shift revenue to earlier periods. Approximately $11.3 million of licensing revenue that was being recognized over the five-year period 2016-2021 is being recognized in the second quarter of 2016. The other significant change under ASC 606 relates to the timing of collaboration revenue when the Company completes its performance obligations for delivery of a drug candidate to its collaboration partners after applying its technologies. For existing collaborations, the effect of ASC 606 is to accelerate revenue recognition to earlier periods. Approximately $6.25 million of collaboration revenue recognized in 2017 and 2018 under historical accounting guidance is being recognized in 2016 under ASC 606. An additional $20.5 million of collaboration revenue that would be recognized in 2018 is being recognized in 2017.

Summary of Significant Accounting Policies | |
Basis of Presentation | Basis of Presentation The accompanying unaudited interim financial statements for Xencor, Inc. (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. Certain amounts in the prior period financial statements have been revised to conform to the presentation of the current period financial statements. See “Recent Accounting Pronouncements – Pronouncements Adopted in 2018. ” The financial statements include all adjustments (consisting only of normal recurring adjustments) that the management of the Company believes are necessary for a fair presentation of the periods presented. The preparation of interim financial statements requires the use of management’s estimates and assumptions that affect reported amounts of assets and liabilities at the date of the interim financial statements and the reported revenues and expenditures during the reported periods. These interim financial results are not necessarily indicative of the results expected for the full fiscal year or for any subsequent interim period. The accompanying unaudited interim financial statements and related notes should be read in conjunction with the audited financial statements and notes thereto included in the Company’s 2017 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 28, 2018. |
Use of Estimates | Use of Estimates The preparation of interim 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, intangible assets and related amortization. Significant estimates in these interim financial statements include estimates made for accrued research and development expenses, stock-based compensation expenses, intangible assets and related amortization. |
Intangible Assets | Intangible Assets The Company maintains definite-lived intangible assets related to certain capitalized costs of acquired licenses and third-party costs incurred in establishing and maintaining its intellectual property rights to its platform technologies and development candidates. These assets are amortized over their useful lives, which are estimated to be the remaining patent life or the contractual term of the license. The straight-line method is used to record amortization expense. The Company assesses its intangible assets for impairment if indicators are present or changes in circumstances suggest that impairment may exist. There were no impairment charges recorded for the three and nine-months ended September 30, 2018 and 2017. The Company capitalizes certain in-process intangible assets that are abandoned when they are no longer pursued. During the nine months ended September 30, 2018 and 2017, the Company abandoned $0.1 million and $0.3 million, respectively, of in-process intangible assets. |
Marketable Securities | Marketable 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 securities issued by investment grade institutions. The Company considers its marketable securities to be available-for-sale. These assets are carried at fair value and the unrealized gains and losses are included in accumulated other comprehensive income (loss). Accrued interest on marketable securities is included in marketable securities. If a decline in the value of a marketable security in the Company’s investment portfolio is deemed to be other-than-temporary, the Company writes down the security to its current fair value and recognizes a loss as a charge against income. The Company reviews its portfolio of marketable securities, using both quantitative and qualitative factors, to determine if declines in fair value below cost are other-than-temporary. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements Pronouncements Adopted in 2018 Effective January 1, 2018, the Company adopted Accounting Standards Codification Topic 606 (ASC 606), Revenue from Contracts with Customers , using the full retrospective transition method. Under this method, the Company is presenting its financial statements for the years ended December 31, 2016 and 2017 and applicable interim periods within the year ended 2017 as if ASC 606 had been effective for those periods. Under ASC 606 an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. A five-step model is used to achieve the core principle: (1) identify the customer contract, (2) identify the contract’s performance obligations, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations and (5) recognize revenue when or as a performance obligation is satisfied. The Company applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. The new guidance provides that revenue recognition for performance obligations related to delivery of certain goods or services occurs when control over the good or service is transferred to the customer. In addition, the timing of revenue recognition from licensing of our intellectual property that are functional and are distinct performance obligations changed from being recognized over the term of access to our license or technology to being recognized at a point in time. See Note 11 “Prior-Period Financial Statements” for a complete discussion of the impact of adopting the new standard. Effective January 1, 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The adoption of this standard did not have an effect on the Company’s statements of cash flow. Effective January 1, 2018, the Company adopted ASU No. 2017-09, Compensation – Stock Compensation (Topic 718) . The standard applies when a company changes the terms of a stock compensation award granted to an employee. The Company did not have any modifications upon adopting the new standard; therefore, adoption of the new standard had no effect on the Company’s financial statements. Pronouncements Not Yet Effective In February 2016, the FASB issued ASU No. 2016-02 Leases . The new guidance requires lessees to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases not considered short term. The new standard will be effective for reporting periods beginning after December 15, 2018. In July 2018, the FASB issued ASU 2018-11, Lease (Topic 842): Targeted Improvements, which provides an alternative transition method of adoption, permitting the recognition of cumulative-effect adjustment to retained earnings on the date of adoption. We are currently evaluating our leases which includes a review of our lease expenses, which are primarily operating lease arrangements for our facilities in Monrovia and San Diego . We intend to adopt the standard on the effective date but have not yet selected a transition method. In June 2018, the FASB issued ASU No. 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods and services. The standard is effective for fiscal years beginning after December 15, 2018 and interim periods within such fiscal year. The Company does not anticipate that the standard will have a significant impact on its financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosures for transfers between Level 1 and Level 2 of the fair value hierarchy, modifies the level 3 disclosure requirements for non-public entities and requires additional disclosure for Level 3 fair value hierarchy. The amendment is effective for fiscal years beginning after December 15, 2019. The Company does not anticipate that the standard will have a significant impact on its financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendment. The amendment is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2019. The Company does not anticipate that the standard will have a significant impact on its financial statements. There have been no other material changes to the significant accounting policies previously disclosed in the Company’s 2017 Annual Report on Form 10-K. |
