Summary of Significant Accounting Policies Summary of Significant Accounting Policies
(a)Basis of Presentation and Principles of Consolidation
The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These statements, however, are condensed and do not include all disclosures required by accounting principles generally accepted in the U.S. (“GAAP”) for complete financial statements and should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the Securities and Exchange Commission (“SEC”) on February 8, 2024.
In the opinion of the management of the Company, the unaudited Condensed Consolidated Financial Statements contain all adjustments (all of which were considered normal and recurring) necessary for a fair statement of the Company’s financial position at March 31, 2024; the results of operations for the three-month periods ended March 31, 2024 and 2023; stockholders' equity for the three-month periods ended March 31, 2024 and 2023; and the cash flows for the three-month periods ended March 31, 2024 and 2023. The Condensed Consolidated Balance Sheet at December 31, 2023 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements.
In accordance with FASB ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has concluded there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the Condensed Consolidated Financial Statements are issued.
On September 28, 2023, the Company effected a 1-for-20 reverse stock split of its common stock (the “Reverse Stock Split”). All references to shares of common stock outstanding, average number of shares outstanding and per share amounts in these Condensed Consolidated Financial Statements and notes to Condensed Consolidated Financial Statements have been restated to reflect the Reverse Stock Split on a retroactive basis.
(b)Use of Estimates and Assumptions
The preparation of the Company’s Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosure of revenue, expenses and certain assets and liabilities at the balance sheet date. Such estimates include the performance obligations under the Company’s collaboration agreements; the collectability of receivables; and the value of certain investments and liabilities. Actual results may differ from such estimates. These interim results are not necessarily indicative of results to be expected for a full year or subsequent interim periods.
(c) Cash Equivalents, Restricted Cash, and Investments
Cash equivalents consist of highly liquid investments purchased with original maturities of three months or less. All other investments are marketable securities.
The Company classified $0.5 million of its cash as restricted cash as of both March 31, 2024 and December 31, 2023. These amounts represent the security deposit associated with the Company’s Lexington, Massachusetts headquarters.
The Company’s short-term investments are marketable debt securities with original maturities of greater than three months from the date of purchase, but less than twelve months from the balance sheet date. Marketable securities consist of commercial paper, corporate bonds and notes, and/or government obligations. All of the Company’s investments have been designated available-for-sale and are stated at fair value. Unrealized gains and losses on investments are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Realized gains and losses, dividends and interest income are included in other income (expense) in the period during which the securities are sold. Any premium or discount arising at purchase is amortized and/or accreted to interest income.
(d)Leases
The Company determines if an arrangement is a lease at contract inception. The Company made an accounting policy election to not recognize leases with an initial term of 12 months or less within its Condensed Consolidated Balance Sheets and to recognize those lease payments on a straight-line basis in its Condensed Consolidated Statements of Operations and Comprehensive Loss over the lease term. Operating lease assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.
As the Company’s lease does not provide an implicit interest rate, the Company uses its incremental borrowing rate, which is based on rates that would be incurred to borrow on a collateralized basis over a term equal to the lease payments in a similar economic environment, in determining the present value of lease payments.
The lease payment used to determine the operating lease asset may include lease incentives, stated rent increases and was recognized as an operating lease right-of-use asset in the Condensed Consolidated Balance Sheets. The Company’s lease agreements may include both lease and non-lease components, which may be accounted for as a single lease component when the payments are fixed. Variable payments included in the lease agreement are expensed as incurred.
The Company’s operating lease is reflected in operating lease right-of-use asset and operating lease liability in the Condensed Consolidated Balance Sheets. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
(e)Other Assets
Other assets consist of long-term prepayments and deposits.
(f)Revenue Recognition
The Company applies the revenue recognition guidance in accordance with FASB Codification Topic 606, Revenue from Contracts with Customers.
The Company recognizes royalty revenues related to Genentech’s and Roche’s sales of Erivedge. For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and where the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). The Company expects to continue recognizing royalty revenue from Genentech’s sales of Erivedge in the U.S. and Roche's sales of Erivedge outside of the U.S. (see Note 8, Research and Development Collaborations). However, a significant portion of Erivedge royalties will be paid to the Purchasers pursuant to the Oberland Purchase Agreement (see Note 7, Liability Related to the Sale of Future Royalties).
(g)Segment Reporting
The Company has determined that it operates in a single reportable segment, which is the research and development of innovative drug candidates for the treatment of human cancer.
(h)New Accounting Pronouncements
Issued, Not Yet Adopted
In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which provides updates to qualitative and quantitative reportable segment disclosure requirements, including enhanced disclosures about significant segment expenses and increased interim disclosure requirements, among others. ASU No. 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods in fiscal years beginning after December 15, 2024. Early adoption is permitted, and the amendments should be applied retrospectively. The Company is currently evaluating the impact of the ASU on the Consolidated Financial Statement disclosures.
In December 2023, the FASB issued ASU No. 2023-09, Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU No. 2023-09 is effective for fiscal years beginning after December 15, 2024 and allows for adoption on a prospective basis, with a retrospective option. Early adoption is permitted. The Company is currently evaluating the impact of the ASU on the income tax disclosures within the Consolidated Financial Statements.
In March 2024, the SEC approved a rule that will require registrants to provide certain climate-related information in their registration statements and annual reports. The rule requires information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks also includes disclosure of a registrant's greenhouse gas emissions. In addition, the rules will require registrants to present certain climate-related financial metrics in their audited financial statements. On April 4, 2024, the SEC voluntarily stayed implementation of this new rule pending judicial review. The Company is evaluating the potential impact of this rule on the Consolidated Financial Statements and related disclosures.
