Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Description of Business, Organization and Liquidity | 1. Description of Business, Organization and Liquidity Business IO Biotech ApS, together with its consolidated subsidiaries, is a clinical-stage biotechnology company dedicated to the identification and development of disruptive immune therapies for the treatment of cancer. We are developing novel, immune-modulating cancer therapies based on our T-win technology platform. As used in these financial statements, unless the context otherwise requires, references to the “Company”, “we,” “us,” and “our” refer to IO Biotech ApS. We were incorporated in Denmark in December 2014. Risks and Uncertainties We are subject to risks common to companies in the biotechnology industry including, but not limited to, new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Product candidates currently under development will require significant additional research and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance reporting capabilities. Our product candidates are in development. There can be no assurance that our research and development will be successfully completed, that adequate protection for our intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if our product development efforts are successful, it is uncertain when, if ever, we will generate significant revenue from product sales. We operate in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, we are dependent upon the services of our employees and consultants. Liquidity Considerations Since inception, we have devoted substantially all our efforts to business planning, conducting research and development, recruiting management and technical staff, and raising capital. We have financed our operations primarily through the issuance of convertible preference shares, convertible notes and, most recently, our initial public offering, or IPO. Our continued discovery and development of its product candidates will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if product development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales. As of September 30, 2021, we had an accumulated deficit of $ 85.0 million. We have incurred losses and negative cash flows from operations since inception, including net losses of $ 46.6 million and $ 12.0 million for the nine months ended September 30, 2021 and the year ended December 31, 2020, respectively. We expect that our operating losses and negative cash flows will continue for the foreseeable future as we continue to develop our product candidates. We currently expect that our cash and cash equivalents of $ 45.5 million as of September 30, 2021 together with the gross cash proceeds of $ 84.1 million received in October 2021 from the issuance of 656,776 class C preference shares and the net proceeds from the IPO, after deducting underwriting discounts, commissions and offering costs, of $ 103.3 million in November 2021, which includes 1,072,500 shares issued upon the full exercise of the underwriters in November 2021 of their option to purchase additional shares of common stock, will be sufficient to fund our operating expenses and capital requirements for at least 12 months from the date the financial statements are issued. However, additional funding will be necessary to fund future discovery research, pre-clinical and clinical activities. We will seek additional funding through public financings, debt financings, collaboration agreements, strategic alliances and licensing arrangements. Although we have been successful in raising capital in the past, there is no assurance that we will be successful in obtaining such additional financing on terms acceptable to it, if at all, and we may not be able to enter into collaborations or other arrangements. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect our business prospects, even our ability to continue operations. Coronavirus Pandemic In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. In order to mitigate the spread of COVID-19, governments have imposed unprecedented restrictions on business operations, travel and gatherings, resulting in a global economic downturn and other adverse economic and societal impacts. The COVID-19 pandemic has also overwhelmed or otherwise led to changes in the operations of many healthcare facilities, including clinical trial sites. While we are considered an essential business under applicable regulations and continue to operate, the impacts of COVID-19 initially placed significant strain on our clinical trial sites, have raised concerns around monitoring patient safety, and resulted in changes to patient visit frequencies. We are continuing to work closely with our clinical partners and have taken steps as necessary to adjust our protocols and timelines due to the impact of the COVID-19 pandemic. The COVID-19 pandemic and its impacts continue to evolve. We cannot predict the scope and severity of any further disruptions as a result of COVID-19 or their impacts on us, but business disruptions for us or any of the third parties with whom we engage, including the collaborators, contract organizations, third-party manufacturers, suppliers, clinical trial sites, regulators and other third parties with whom we conduct business could materially and negatively impact our ability to conduct our business in the manner and on the timelines presently planned. The extent to which the COVID-19 pandemic may continue to impact our business and financial performance will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope and duration of the pandemic, the extent and effectiveness of government restrictions and other actions, including relief measures, implemented to address the impact of the pandemic, and resulting economic impacts. The actual and perceived impact of the COVID-19 pandemic is changing daily, and its ultimate effect on our business cannot be predicted. As a result, there can be no assurance that we will not experience additional negative impacts associated with COVID-19, which could be significant. The COVID-19 pandemic may negatively impact our business, financial condition and results of operations causing interruptions or delays in the Company’s programs and services. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies There have been no changes to the significant accounting policies as disclosed in Note 2 to the Company’s annual financial statements for the years ended December 31, 2020 and 2019 included in the final prospectus for the Company’s IPO filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on November 8, 2021 (the "Prospectus"). Principles of consolidation The Company’s condensed consolidated financial statements include the accounts of its subsidiaries IO Bio US, Inc. and IO Biotech Limited. IO Bio US, Inc., a wholly owned subsidiary of IO Biotech ApS, was incorporated in Delaware in May 2021. IO Biotech Limited, a wholly owned subsidiary of IO Biotech ApS, was incorporated in the UK in August 2021. In October 2021, the Company engaged in a series of transactions, referred to collectively as the Corporate Reorganization. As a result of the Corporate Reorganization, IO Biotech ApS became a wholly-owned subsidiary of IO Biotech, Inc. and accordingly, our consolidated financial statements will be those of IO Biotech, Inc. for the periods after the date of the Corporate Reorganization. IO Biotech, Inc. is a recently formed holding company, which, prior to our IPO, had nominal assets and no liabilities, contingencies, or commitments, and which has not conducted any operations prior to our IPO other than acquiring the entire issued and outstanding stock of IO Biotech ApS. The Company, IO Biotech ApS, and the holders of all of the issued and outstanding equity interests of IO Biotech ApS have entered into a Share Contribution and Exchange Agreement, dated as of October 29, 2021, pursuant to which the Corporate Reorganization was effected. Unaudited Financial Information The Company’s condensed financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. In the Company’s opinion, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company consider events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. Restatement of Prior Period Financial Statements. In connection with the preparation of our consolidated financial statements, we identified an error related to the recording of an accrued expense as of June 30, 2021, which led to the overstatement of research and development expenses for the six months ended June 30, 2021. As previously disclosed in our Current Report on Form 8-K filed on December 17, 2021, we have restated our previously reported Unaudited Interim Condensed Financial Statements as of June 30, 2021 and for the Six Months Ended June 30, 2021 and 2020 for this error. Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , as amended, with guidance regarding the accounting for and disclosure of leases. ASU 2016-02 requires lessees to recognize the liabilities related all leases, including operating leases, with a term greater than 12 months on the balance sheet. This update also requires lessees and lessors to disclose key information about their leasing transactions. This standard is effective for annual reporting periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements and financial statement disclosures. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments . ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU 2016-13 within ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging , and Topic 825, Financial Instruments , or ASU 2016-13. The guidance is effective for fiscal years beginning after December 15, 2022. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements and financial statement disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes , or ASU 2019-12. ASU 2019-12 eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the impact adoption of ASU 2019-12 will have on our financial statements and disclosures. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (i) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective for us beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are currently assessing the impact adoption of ASU 2020-06 will have on our financial statements and disclosures. |

Fair Value Measurements | 3. Fair Value Measurements The following table presents information about our financial assets and liabilities measured at fair value on a recurring basis and indicate the level of the fair value hierarchy utilized to determine such fair values (in thousands): September 30, 2021 Total Level 1 Level 2 Level 3 Current liabilities Preference shares tranche obligations $ 28,276 $ — $ — $ 28,276 Total financial liabilities measured at fair value $ 28,276 $ — $ — $ 28,276 The following table presents a roll-forward of the fair value of the convertible note and preference shares tranche obligations for which fair value is determined by Level 3 inputs (in thousands): Preference Convertible Total Balance, January 1, 2020 $ — $ 8,663 $ 8,663 Fair value adjustments — 1,985 1,985 Currency exchange — ( 375 ) ( 375 ) Conversion into class B preference shares — ( 10,273 ) ( 10,273 ) Balance, December 31, 2020 — — — Addition on issuance of class C preference shares 2,425 — 2,425 Fair value adjustments 26,830 — 26,830 Currency exchange ( 979 ) — ( 979 ) Balance, September 30, 2021 $ 28,276 $ — $ 28,276 Valuation techniques used to measure fair value maximize the use of relevant observable inputs and minimize the use of unobservable inputs. Our convertible notes were classified within Level 3 of the fair value hierarchy because the fair value measurement was based, in part, on significant inputs not observed in the market. In July 2019, we issued convertible notes to existing related party investors for proceeds of $ 9.0 million. Upon issuance, we elected the fair value option to account for the convertible notes, with any subsequent changes in fair value being recognized through the statements of operations as other income (expense) until the convertible notes are settled. We have not recorded interest expense separate from those fair value adjustments. The convertible notes accrued interest at 8 % per year beginning in August 2019 payable in cash or, at the investor’s discretion, into our class B or class C preference shares. In April 2020, the convertible notes plus accrued interest of $ 0.5 million, were converted according to the terms of the convertible notes into 142,437 shares of class B preference shares (Note 8). On conversion in April 2020, we determined the fair value of the convertible notes with reference to the class B preference shares (Note 8) into which the convertible notes were converted. Our class C Preference Shares Tranche Obligation is measured at fair value using a Black-Scholes option pricing valuation methodology. The fair value of class C Preference Shares Tranche Obligation includes inputs not observable in the market and thus represents a Level 3 measurement. The option pricing valuation methodology utilized requires inputs based on certain subjective assumptions, including (i) expected stock price volatility, (ii) calculation of an expected term, (iii) a risk-free interest rate, and (iv) expected dividends. The assumptions utilized to value the class C Preference Shares Tranche Obligation as of September 30, 2021 were (i) expected stock price volatility of 73.7 %; (ii) remaining term of 0.3 years; (iii) a risk-free interest rate of 0.05 %; and (iv) an expectation of no dividends. There were no transfers among Level 1, Level 2 or Level 3 categories in the nine months ended September 30, 2021 and year ended December 31, 2020. |

Commitments and Contingencies | 7. Commitments and Contingencies Lease Commitments We have two operating leases in Copenhagen, Denmark for office space that expire in August 2021 and December 2021 , respectively. In March 2021, we entered into a new lease for our office space in Copenhagen, Denmark that expires in January 2025 , terminable upon three months’ notice. Rent expense for the nine months ended September 30, 2021 and 2020 was $ 210,000 and $ 147,000 respectively, and for the three months ended September 30, 2021 and 2020 was $ 81,000 and $ 64,000 , respectively. Legal Proceedings From time to time, we may be party to litigation arising in the ordinary course of its business. We were not subject to any material legal proceedings during the nine months ended September 30, 2021 and year ended December 31, 2020, and, to our knowledge, no material legal proceedings are currently pending or threatened. Research Agreements The Company and the Herlev University Hospital in Denmark (“Herlev”) have a number of existing agreements for scientific and other support of the Company’s ongoing development activities. In January 2021, the Company entered into an additional agreement with Herlev regarding the payment of specific services whereupon in addition to any consideration payable by the Company to Herlev pursuant to the existing agreements the Company shall pay a fee to Herlev of DKK 5.0 million (approximately $ 0.8 million) in the event of an initial public offering or other liquidity event whereby all or substantially all of the value of the Company is realized in consideration for cash. The Company consummated its IPO in November 2021, resulting in this payment to Herlev becoming payable. Additionally, upon the completion of the IPO, the Company is obligated to make payments to Herlev in the aggregate amount of DKK 13.6 million, (which is approximately $ 2.1 million based on the exchange rate of DKK 6.43 to one U.S. dollar on September 30, 2021) including the DKK 5.0 million previously mentioned. Indemnification Agreements We enter into certain types of contracts that contingently requires us to indemnify various parties against claims from third parties. These contracts primarily relate to procurement, service, consultancy or license agreements under which we may be required to indemnify vendors, service providers or licensees for certain claims, including claims that may be brought against them arising from our acts or omissions with respect to our products, technology, intellectual property or services. From time to time, we may receive indemnification claims under these contracts in the normal course of business. In the event that one or more of these matters were to result in a claim against us, an adverse outcome, including a judgment or settlement, may cause a material adverse effect on our future business, operating results or financial condition. It is not possible to estimate the maximum amount potentially payable under these contracts since we have no history of prior indemnification claims and the unique facts and circumstances involved in each particular claim will be determinative. |

Temporary Equity Disclosure [Abstract] | |
Convertible Preference Shares | 8. Convertible Preference Shares As of September 30, 2021 and December 31, 2020 , we had 584,583 class B preference shares authorized, issued and outstanding. As of September 30, 2021 , we had 1,263,804 class C preference shares authorized and 538,088 class C preference shares issued and outstanding. In April 2020, we issued 142,437 class B preference shares at a subscription price of $ 64.48 per share to existing related-party investors upon the conversion of convertible notes (Note 3). We recorded the 142,437 class B preference shares at fair value of $ 10.3 million ($ 72.15 per share) determined using an option pricing model, or OPM, assuming a Company equity value of $ 40.6 million, a term of 1.6 years, volatility of 86.0 % and a risk-free rate of 0.18 %. We incurred issuance costs of $ 4,000 in connection with the issuances of the class B preference shares on conversion of the convertible notes. In July 2020, we issued 75,845 class B preference shares to existing related-party investors at a subscription price of $ 67.46 per share for gross cash proceeds of $ 5.1 million. We recorded the 75,845 class B preference shares at fair value of $ 5.6 million ($ 73.60 per share), resulting in a deemed dividend of $ 0.5 million recorded against additional paid-in capital on our balance sheet. Fair value of the class B preference shares issued on this date was determined using an OPM methodology assuming a Company equity value of $ 47.6 million, a term of 1.36 years, volatility of 92.4 % and a risk-free rate of 0.16 %. We incurred issuance costs of $ 10,000 in connection with the issuances of the class B preference shares. In January 2021, we completed an investment agreement, Class C Investment Agreement, for the sale and issuance of up to 1,263,804 class C preference shares to new investors and existing related-party investors at a subscription price of $ 121.55 per share. Then, pursuant to the Class C Investment Agreement, we issued 505,520 class C preference shares for gross cash proceeds of $ 61.5 million. The Class C Investment Agreement further provides for a milestone closing in the event of certain development milestones before April 2022, whereby purchasers of class C preference shares are obligated to a further subscription amount of $ 88.4 million, or the Preference Shares Tranche Obligation, which resulted in a further issuance of 689,344 class C preference shares at a subscription price of $ 128.19 per share. We incurred issuance costs of $ 340,000 in connection with the issuances of the class C preference shares. We concluded that the Preference Shares Tranche Obligation met the definition of a freestanding financial instrument, as it is legally detachable and separately exercisable from the class C preference shares. Therefore, we allocated the proceeds received from the issuance of shares under the Class C Investment Agreement between the Preference Shares Tranche Obligation and the class C preference shares. The fair value of the Preference Shares Tranche Obligation of $ 2.4 million on issuance was allocated from the $ 61.5 million proceeds of the class C preference shares financing and is classified as a current liability on the balance sheet as of September 30, 2021 as the class C preference shares would become redeemable upon a Deemed Liquidation Event, the occurrence of which is not within our control. In March 2021, prior to a milestone closing, an investor elected to purchase and we issued 35,825 class C preference shares for gross cash proceeds of $ 4.2 million pursuant to the Class C Investment Agreement. As a result of entering into a collaboration agreement with Merck in September 2021, the number of class C preference shares issued in March 2021 was adjusted downward to 32,568 class C preference shares. In October 2021, investors purchased and we issued 656,776 class C preference shares for gross cash proceeds of $ 84.1 million pursuant to the Class C Investment Agreement. Preferences, Privileges and Rights Our class C preference shares and our class B preference shares together constitute our preferred classes of stock, or Preference Shares. Our Preference Shares have the following rights, preferences, privileges and restrictions: Liquidity Preference Company liquidity events, or Liquidity Events, include assignment or transfer of all or part of the shares from our shareholders as a whole, listing of our shares, merger, demerger, liquidation or other dissolution of the Company, payment of dividends, reduction of our share capital for distribution to shareholders.

Distribution preferences pursuant to (i) and (ii) above, together the Liquidity Preference. Conversion Option Our Preference Shares are convertible at the option of the holder at any time on a one-for-one basis into our class A ordinary shares. Voting Rights and Board Representation The holders of Preference Shares are entitled to one vote per share on all matters to be voted upon at all shareholder meetings and written actions in lieu of meetings. The holders of Preference Shares are entitled to elect six of the eight directors on our board.

The adjustment shall be made through the issuance of new Preference Shares of the relevant class to the Preference Shareholders at quota value.

We did no t record a provision or benefit for income taxes during the nine months ended September 30, 2021 and 2020. We continue to maintain a full valuation allowance against all of our deferred tax assets. We have evaluated the positive and negative evidence involving our ability to realize our deferred tax assets. We have considered our history of cumulative net losses incurred since inception and our lack of any commercial products. We have concluded that it is more likely than not that we will not realize the benefits of our deferred tax assets. We reevaluate the positive and negative evidence at each reporting period. |

IO Bio US, Inc., a wholly owned subsidiary of IO Biotech ApS, was incorporated in Delaware in May 2021. IO Biotech Limited, a wholly owned subsidiary of IO Biotech ApS, was incorporated in the UK in August 2021. In October 2021, the Company engaged in a series of transactions, referred to collectively as the Corporate Reorganization. As a result of the Corporate Reorganization, IO Biotech ApS became a wholly-owned subsidiary of IO Biotech, Inc. and accordingly, our consolidated financial statements will be those of IO Biotech, Inc. for the periods after the date of the Corporate Reorganization. IO Biotech, Inc. is a recently formed holding company, which, prior to our IPO, had nominal assets and no liabilities, contingencies, or commitments, and which has not conducted any operations prior to our IPO other than acquiring the entire issued and outstanding stock of IO Biotech ApS. The Company, IO Biotech ApS, and the holders of all of the issued and outstanding equity interests of IO Biotech ApS have entered into a Share Contribution and Exchange Agreement, dated as of October 29, 2021, pursuant to which the Corporate Reorganization was effected. |
Unaudited Financial Information | Unaudited Financial Information The Company’s condensed financial statements included herein have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC. In the Company’s opinion, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the financial position and results of operations for the reported interim periods. The Company consider events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period. |
Restatement of Prior Period Financial Statements. | Restatement of Prior Period Financial Statements. In connection with the preparation of our consolidated financial statements, we identified an error related to the recording of an accrued expense as of June 30, 2021, which led to the overstatement of research and development expenses for the six months ended June 30, 2021. As previously disclosed in our Current Report on Form 8-K filed on December 17, 2021, we have restated our previously reported Unaudited Interim Condensed Financial Statements as of June 30, 2021 and for the Six Months Ended June 30, 2021 and 2020 for this error. |
Recently Issued Accounting Standards | Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , as amended, with guidance regarding the accounting for and disclosure of leases. ASU 2016-02 requires lessees to recognize the liabilities related all leases, including operating leases, with a term greater than 12 months on the balance sheet. This update also requires lessees and lessors to disclose key information about their leasing transactions. This standard is effective for annual reporting periods beginning after December 15, 2021, and interim periods within annual periods beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements and financial statement disclosures. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments . ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU 2016-13 within ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging , and Topic 825, Financial Instruments , or ASU 2016-13. The guidance is effective for fiscal years beginning after December 15, 2022. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements and financial statement disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes , or ASU 2019-12. ASU 2019-12 eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the impact adoption of ASU 2019-12 will have on our financial statements and disclosures. In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (i) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective for us beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are currently assessing the impact adoption of ASU 2020-06 will have on our financial statements and disclosures. |
