Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and Basis of Presentation | 1. Organization and Basis of Presentation Cue Biopharma, Inc. (the "Company") is a clinical-stage biopharmaceutical company developing a novel class of injectable biologics designed to selectively engage and modulate tumor-specific T cells within the body to treat a broad range of cancers, chronic infectious diseases, and autoimmune diseases. The Company’s corporate office and research facilities are located in Boston, Massachusetts. The Company is in the development stage and has incurred recurring losses and negative cash flows from operations since inception. As of June 30, 2023 , the Company had cash, cash equivalents, and marketable securities of approximately $ 57,889,000 . Management believes that current cash, cash equivalents, and marketable securities on hand at June 30, 2023 are sufficient to fund operations for at least the next twelve months from the date of issuance of these financial statements; however, the future viability of the Company is dependent on its ability to raise additional capital to finance its operations and to fund research and development costs in order to seek approval for commercialization of its drug product candidates. The Company’s failure to raise capital as and when needed would have a negative impact on its financial condition and its ability to pursue its business strategies as this capital is necessary for the Company to perform the research and development activities required to develop and commercialize the Company’s drug product candidates in order to generate future revenue streams. |

Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements as of June 30, 2023, and for the three and six months ended June 30, 2023 and 2022, have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and generally accepted accounting principles in the United States (“U.S. GAAP”) for financial information, which prescribes elimination of all significant intercompany accounts and transactions in the accounts of the Company and its wholly owned subsidiary, Cue Biopharma Securities Corp., which was incorporated in the Commonwealth of Massachusetts in December 2018. In the opinion of management, these financial statements reflect all adjustments which are necessary for a fair statement of the Company’s financial position and results of its operations, as of and for the periods presented. These financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on March 21, 2023. Interim results for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2023, or any future periods. Public Offerings In October 2021, the Company entered into an open market sale agreement (the “October 2021 ATM Agreement”) with Jefferies LLC ("Jefferies"), as agent, to sell shares of the Company’s common stock for aggregate gross proceeds of up to $ 80 million, from time to time, through an at-the-market equity offering program. The October 2021 ATM Agreement will terminate upon the earliest of (a) the sale of $ 80 million of shares of the Company’s common stock pursuant to the October 2021 ATM Agreement or (b) the termination of the October 2021 ATM Agreement by the Company or Jefferies. During the three and six months ended June 30, 2023 , the Company sold 536,264 shares of common stock under the October 2021 ATM Agreement for proceeds of approximately $ 2,015,000 net of commission paid, but excluding transaction expenses. As of June 30, 2023, the Company had sold an aggregate of 4,129,671 shares of common stock under the October 2021 ATM Agreement for proceeds of approximately $ 25.6 million, net of commissions paid, but excluding transaction expenses, since its inception. Consolidation The accompanying consolidated financial statements include the Company and its wholly owned subsidiary, Cue Biopharma Securities Corp. The Company has eliminated all intercompany transactions. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant estimates include estimates related to collaboration revenue, the accounting for potential liabilities and accrued expenses, the assumptions utilized in valuing stock-based compensation issued for services, the realization of deferred tax assets, and the useful life with respect to long-lived assets and intangibles. Actual results could differ from those estimates. Cash Concentrations The Company maintains its cash balances with financial institutions in federally insured accounts and may periodically have cash balances in excess of insurance limits. The Company maintains its accounts with financial institutions with a high credit rating. The Company has not experienced any losses to date from our deposits with these financial institutions and believes that it is not exposed to any significant credit risk on cash. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. The Company currently invests available cash in money market funds. Marketable Securities Marketable securities consist of investments with original maturities greater than ninety days and less than one year from the balance sheet date. The Company classifies all of its investments as available-for-sale securities. Accordingly, these investments are recorded at fair value, which is based on quoted market prices. Unrealized gains and losses are recognized and determined on a specific identification basis and are included in other comprehensive loss. Realized gains and losses are determined on a specific identification basis and are included in other income on the consolidated statement of operations and other comprehensive loss. Amortization and accretion of discounts and premiums is recorded in interest income. The Company has invested available cash in U.S. Treasury obligations. Restricted Cash The Company had $ 150,000 in restricted cash deposited with separate commercial banks to collateralize a credit card as of June 30, 2023 and December 31, 2022 . Property and Equipment Property and equipment is recorded at cost. Major improvements are capitalized, while maintenance and repairs are charged to expense as incurred. Gains and losses from dispositions of property and equipment are included in income and expense when realized. Amortization of leasehold improvements is provided using the straight-line method over the shorter of the lease term or the useful life of the underlying assets. Depreciation of property and equipment is provided using the straight-line method over the following estimated useful lives: Laboratory equipment 5 years Computer and office equipment 3 years Furniture and fixtures 3 - 8 years The Company recognizes depreciation and amortization expense in general and administrative expenses and in research and development expenses in the Company’s consolidated statements of operations and comprehensive loss, depending on how each category of property and equipment is utilized in the Company’s business activities. Trademark Trademark consists of the Company’s right, title and interest to the CUE BIOLOGICS Mark, and any derivative mark incorporating CUE, throughout the world, together with all associated goodwill and common law rights appurtenant thereto, including, but not limited to, any right, title and interest in any corporate name, company name, business, name, trade name, dba, domain name, or other source identifier incorporating CUE. The Company has classified the trademark as a component of other long-term assets, having a useful life of 15 years. The Company evaluates the status of this intangible asset for amortization and impairment at each quarter end and year end reporting date. For each of the three and six months ended June 30, 2023 and 2022, the Company recorded approximately $ 3,000 and $ 6,000 , respectively, in amortization expense on a straight-line basis. Debt Issuance Costs Debt issuance costs are deferred and presented as a reduction to long-term debt. Debt issuance costs are amortized using the effective interest rate method over the term of the loan. Amortization of deferred debt issuance costs are included in interest expense in the consolidated statements of operations and other comprehensive loss. Revenue Recognition The Company recognizes collaboration revenue under certain of the Company’s license and collaboration agreements that are within the scope of Accounting Standards Codification (“ASC”), Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company’s contracts with customers typically include promises related to licenses to intellectual property and research and development services. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. Accordingly, the transaction price is generally comprised of a fixed fee due at contract inception and variable consideration in the form of milestone payments due upon the achievement of specified events and tiered royalties earned when customers recognize net sales of licensed products. The Company measures the transaction price based on the amount of consideration to which it expects to be entitled in exchange for transferring the promised goods and/or services to the customer. The Company utilizes the “most likely amount” method to estimate the amount of variable consideration, to predict the amount of consideration to which it will be entitled for its one open contract. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. At the inception of each arrangement that includes development and regulatory milestone payments, the Company evaluates whether the associated event is considered probable of achievement and estimates the amount to be included in the transaction price using the expected value method. Research and Development Expenses Research and development expenses consist primarily of compensation costs, fees paid to consultants, outside service providers and organizations (including research institutes at universities), facility costs, and development and clinical trial costs with respect to the Company’s drug product candidates. Research and development expenses incurred under contracts are expensed ratably over the life of the underlying contracts, unless the achievement of milestones, the completion of contracted work, or other information indicates that a different pattern of performance is more appropriate. Other research and development expenses are charged to operations as incurred. Nonrefundable advance payments are recognized as an expense as the related services are performed. The Company evaluates whether it expects the services to be rendered at each quarter end and year end reporting date. If the Company does not expect the services to be rendered, the advance payment is charged to expense. Nonrefundable advance payments for research and development services are included in prepaid and other current assets on the balance sheet. To the extent that a nonrefundable advance payment is for contracted services to be performed within 12 months from the reporting date, such advance is included in current assets; otherwise, such advance is included in non-current assets. The Company evaluates the status of its research and development agreements and contracts, and the carrying amount of the related assets and liabilities, at each quarter end and year end reporting date, and adjusts the carrying amounts and their classification on the balance sheet as appropriate. Patent Expenses The Company is the exclusive worldwide licensee of, and has patent applications pending for, numerous domestic and foreign patents. Due to the significant uncertainty associated with the successful development of one or more commercially viable drug product candidates based on the Company’s research efforts and any related patent applications, all patent costs, including patent-related legal fees, filing fees and other costs are charged to general and administrative expense as incurred. For the three and six months ended June 30, 2023 , patent expenses were approximately $ 514,000 and $ 1,146,000 , respectively. For the three and six months ended June 30, 2022, patent expenses were $ 564,000 and $ 1,230,000 , respectively. Licensing Fees and Costs Licensing fees and costs consist primarily of costs relating to the acquisition of the Company’s license agreement (the “Einstein License Agreement”) with the Albert Einstein College of Medicine (“Einstein”), including related royalties, maintenance fees, milestone payments and product development costs. Licensing fees and costs are charged to research and development expense as incurred. Long-Lived Assets The Company reviews long-lived assets, consisting of property and equipment, for impairment at each fiscal year end or when events or changes in circumstances indicate the carrying value of these assets may exceed their current fair values. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the assets. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated. The Company has not historically recorded any impairment to its long-lived assets. In the future, if events or market conditions affect the estimated fair value to the extent that a long-lived asset is impaired, the Company will adjust the carrying value of these long-lived assets in the period in which the impairment occurs. Leases The Company accounts for leases under ASC 842 Leases, which requires a lessee to record a right-of-use asset and a corresponding lease liability for most lease arrangements on the balance sheet. Under the standard, disclosure of key information about leasing arrangements to assist users of the financial statements with assessing the amount, timing and uncertainty of cash flows arising from leases are required. Stock-Based Compensation The Company periodically issues stock-based awards to officers, directors, employees, Scientific and Clinical Advisory Board members and consultants for services rendered. Such issuances vest and expire according to terms established at the issuance date. Stock-based payments to officers, directors, employees, Scientific and Clinical Advisory Board members and consultants, including grants of employee stock options, are recognized in the financial statements based on their grant date fair values. Stock option grants, which are generally time-vested, are measured at the grant date fair value and charged to operations on a straight-line basis over the service period, which generally approximates the vesting term. The Company also grants performance-based awards periodically to officers of the Company. The Company recognizes compensation costs related to performance awards over the requisite service period if and when the Company concludes that it is probable that the performance condition will be achieved. The fair value of stock options and restricted stock units is determined utilizing the Black-Scholes option-pricing model, which is affected by several variables, including the risk-free interest rate, the expected dividend yield, the life of the equity award, the exercise price of the stock option as compared to the fair value of the common stock on the grant date, and the estimated volatility of the common stock over the term of the equity award. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Until the Company has established a trading history for its common stock that approximates the expected term of the options, estimated volatility is based on the average historical volatilities of comparable public companies in a similar industry. The expected dividend yield is based on the current yield at the grant date; the Company has never declared or paid dividends and has no plans to do so for the foreseeable future. As permitted by Staff Accounting Bulletin No. 107, due to the Company’s limited trading history and option activity, management utilizes the simplified method to estimate the expected term of options at the date of grant. The exercise price is determined based on the fair value of our common stock at the date of grant. The Company accounts for forfeitures as they occur. The Company recognizes the fair value of stock-based compensation in general and administrative expenses and in research and development expenses in the Company’s consolidated statements of operations and comprehensive loss, depending on the type of services provided by the recipient of the equity award. Comprehensive Income (Loss) Components of comprehensive income or loss, including net income or loss, are reported in the financial statements in the period in which they are recognized. Other comprehensive income or loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net income (loss) and other comprehensive income (loss) are reported net of any related tax effect to arrive at comprehensive income (loss). Comprehensive income (loss) includes net income (loss) as well as changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. The Company’s only element of other comprehensive income (loss) in periods presented was unrealized gain or loss on available-for-sale securities. Earnings (Loss) Per Share The Company’s computation of earnings (loss) per share (“EPS”) for the respective periods includes basic and diluted EPS. Basic EPS is measured as the income (loss) attributable to common stockholders divided by the weighted average number of common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares that would result from the exercise of outstanding stock options and warrants as if they had been exercised at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. Basic and diluted loss per common share is the same for all periods presented because all outstanding stock options and warrants are anti-dilutive. Per ASC 260-10-45-13, shares issuable for little to no consideration should be included in the number of outstanding shares used for basic EPS. The FASB proposed that warrants or options exercisable for little to no cost (sometimes referred to as “penny warrants”) be included in the denominator of basic EPS (and therefore diluted EPS) once there were no further vesting conditions or contingencies associated with them. The Company included 1,531,440 pre-funded warrants in the denominator of basic EPS at June 30, 2023. At June 30, 2023 and 2022, the Company excluded the outstanding securities summarized below, which entitle the holders thereof to acquire shares of common stock, from its calculation of earnings per share, as their effect would have been anti-dilutive. June 30, 2023 2022 Common stock warrants 10,719,846 789,358 Common stock options 7,104,675 6,306,354 Nonvested restricted stock units - 6,667 Total 17,824,521 7,102,379 Fair Value of Financial Instruments The authoritative guidance with respect to fair value established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories, as presented below. Level 1. Observable inputs such as quoted prices in active markets for an identical asset or liability that the Company has the ability to access as of the measurement date. Financial assets and liabilities utilizing Level 1 inputs include active exchange-traded securities and exchange-based derivatives. Level 2. Inputs, other than quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include fixed income securities, non-exchange-based derivatives, mutual funds, and fair-value hedges. Level 3. Unobservable inputs in which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. Financial assets and liabilities utilizing Level 3 inputs include infrequently traded non-exchange-based derivatives and commingled investment funds and are measured using present value pricing models. The Company determines the level in the fair value hierarchy within which each fair value measurement falls in its entirety, based on the lowest level input that is significant to the fair value measurement in its entirety. In determining the appropriate levels, the Company performs an analysis of the assets and liabilities at each reporting period end. The Company had approximately $ 52,901,000 in cash equivalents and approximately $ 4,988,000 in short-term marketable securities that were measured and recorded at fair value on the Company’s balance sheet as of June 30, 2023 . The Company had approximately $ 45,423,000 in cash equivalents and approximately $ 24,675,000 in short-term marketable securities that were measured and recorded at fair value on the Company’s balance sheet at December 31, 2022. The carrying value of financial instruments (consisting of cash, a certificate of deposit, accounts payable, accrued compensation and accrued expenses) is considered to be representative of their respective fair values due to the short-term nature of those instruments. Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update ("ASU") No. 2016-13 , Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326) (CECL). The new standard requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new standard is effective for annual reporting periods beginning after December 15, 2022, including interim reporting periods within each annual reporting period for smaller reporting companies. T he Company adopted ASU No. 2016-13 but there was no financial impact to the Company’s consolidated financial statements for the year ended December 31, 2022 or for the six months ended June 30, 2023. Management does not believe that any other recently issued, but not yet effective, authoritative guidance, if currently adopted, would have a material impact on the Company’s financial statement presentation or disclosures. |

Fair Value | 3. Fair Value The Company accounts for its financial assets and liabilities using fair value measurements. The authoritative accounting guidance defines fair value, establishes a framework for measuring fair value under U.S. GAAP and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following table presents information about the Company’s assets that are measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022, and indicate the level of the fair value hierarchy utilized to determine such fair value: Fair Value Measurements as of June 30, 2023 (in thousands) Level 1 Level 2 Level 3 Fair Value Cash equivalents $ 52,901 $ — $ — $ 52,901 Marketable securities — $ 4,988 — 4,988 Total $ 52,901 $ 4,988 $ — $ 57,889 Fair Value Measurements as of December 31, 2022 (in thousands) Level 1 Level 2 Level 3 Fair Value Cash equivalents $ 45,423 $ — $ — $ 45,423 Marketable securities — 24,675 — 24,675 Total $ 45,423 $ 24,675 $ — $ 70,098 As of June 30, 2023 , the Company reported approximately $ 52,901,000 and $ 4,988,000 in cash equivalents and marketable securities, respectively. The Company measures the cash equivalents that are invested in money market funds using Level 1 inputs for identical securities. The Company measures the fair value of marketable securities that are invested in U.S. Treasury securities using Level 2 inputs and primarily relies on quoted prices in active markets for similar marketable securities. As of December 31, 2022, the Company reported approximately $ 45,423,000 and $ 24,675,000 in cash equivalents and marketable securities, respectively. During the three and six months ended June 30, 2023 , and the year ended December 31, 2022, there were no transfers between Level 2 and Level 3. The carrying values of accounts receivable, prepaid expenses, other current assets, debt, accounts payable and accrued expenses approximate their fair value due to the short-term nature of these balances. |

Debt Disclosure [Abstract] | |
Loan with Silicon Valley Bank | 6. Loan with Silicon Valley Bank On February 15, 2022 (the “Closing Date”), the Company entered into a Loan and Security Agreement (the “Loan Agreement”), with Silicon Valley Bank, as lender (“Lender”). The Company drew $ 10,000,000 in term loans under the Loan Agreement (the "Term Loans") on the Closing Date. The Loan Agreement was amended in April 2023. The Term Loans bear interest at a floating rate per annum equal to the greater of (A) the prime rate (as published in the money rates section of The Wall Street Journal) plus 2.25 % and (B) 5.50 %. The Term Loans are interest only from the Closing Date through June 30, 2023 , after which the Company is required to pay 30 equal monthly installments of principal. At June 30, 2023 , the interest rate was 10.5 % based on the prime rate plus 2.25 %. The Term Loans may be prepaid in full prior to February 15, 2024 with payment of a 2.00 % prepayment premium, on or after which they may be prepaid in full with payment of a 1.00 % prepayment premium. Upon prepayment or repayment in full of the Term Loans, the Company will be required to pay a one-time final payment fee equal to 5.00 % of the original principal amount of any funded Term Loans being repaid. This one-time final payment fee is recorded to interest expense using the effective interest method over the period of the Term Loans in the consolidated statements of operation and other comprehensive loss. The Term Loans and related obligations under the Loan Agreement are secured by substantially all of the Company’s properties, rights and assets, except for its intellectual property which is subject to a negative pledge under the Loan Agreement. The Loan Agreement contains customary representations, warranties, events of default and covenants, including a requirement that the Company maintain in accounts of the Company at the Lender unrestricted and unencumbered cash equal to the lesser of all of the Company’s cash or $ 20,000,000 . On March 10, 2023, Silicon Valley Bank ("SVB") was closed by state regulators and the Federal Deposit Insurance Company ("FDIC") was appointed receiver for the bank. The FDIC created a successor bridge bank, Silicon Valley Bridge Bank, N.A. (“SVBB”) and all deposits of SVB were transferred to SVBB under a systemic risk exception approved by the U.S. Department of the Treasury, the Federal Reserve and the FDIC. SVBB continues to hold the Company’s Term Loans under the same existing terms and covenants which were in place with SVB. During the three and six months ended June 30, 2023 , the Company recognized interest expense related to the Term Loans of $ 350,000 and $ 594,000 , respectively, and $ 33,000 and $ 65,000 , respectively, in interest expense related to accretion of the final payment. During the three and six months ended June 30, 2022, the Company recognized interest expense related to the Term Loans of $ 150,000 and $ 171,000 , respectively, and $ 43,000 in interest expense related to accretion of the final payment for the three months and six months ended June 30, 2022.

Warrants and Rights Note Disclosure [Abstract] | |
Warrants | 8. Warrants The Company has one tranche of common stock warrants outstanding at June 30, 2023 . The Company issued warrants exercisable for 1,500 shares of common stock on June 15, 2015 with an exercise price of $ 2.70 per share, which warrants expired at the end of their 7-year term on June 15, 2022 . The Company issued another tranche of warrants exercisable for an aggregate of 882,071 shares of common stock with an exercise price of $ 9.38 per share when issued on December 27, 2017, which warrants expired at the end of their 5 -year term on December 26, 2022 . On November 16, 2022, the Company issued in a private placement 9,188,406 warrants with an exercise price of $ 3.93 and 1,531,440 pre-funded warrants. Each tranche of warrants was evaluated under ASC 480, Distinguishing Liabilities from Equity , and ASC 815, Derivatives and Hedging, and the Company determined that equity classification was appropriate. The Company determined equity classification for both warrants and pre-funded warrants as they do not embody an obligation for the Company to repurchase its shares and permit the holders to receive a fixed number of shares of common stock upon exercise. Per ASC 815-40-25, the Company will account for the warrants and pre-funded warrants as equity, as the Company does not provide to the holder a fixed or guaranteed return. The Company recorded cash received from 1,531,440 pre-funded warrants to additional paid in capital in the amount of $ 4,999,999 . The Company recorded placement fees and expenses related to the sale of pre-funded warrants in the amount of $ 299,999 as a charge to additional paid in capital in the consolidated balance sheet at December 31, 2022. Per ASC 260-10-45-13, shares issuable for little to no consideration should be included in the number of outstanding shares used for basic EPS. The FASB proposed that warrants or options exercisable for little to no cost (sometimes referred to as “penny warrants”) be included in the denominator of basic EPS (and therefore diluted EPS) once there were no further vesting conditions or contingencies associated with them. The Company included 1,531,440 pre-funded warrants in the denominator of basic EPS at June 30, 2023.

Revenue from Contract with Customer [Abstract] | |
Collaboration Revenue | 9. Collaboration Revenue The Company recognizes collaboration revenue under certain of the Company’s license or collaboration agreements that are within the scope of ASC 606. The Company’s contracts with customers typically include promises related to licenses to intellectual property and research and development services. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and if, over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company’s contracts may include options to acquire additional goods and/or services. The terms of the Company’s arrangements with customers typically include the payment of one or more of the following: (i) non-refundable, up-front payment, and pass through costs related to research activities, (ii) development, regulatory and commercial milestone payments, (iii) future options and (iv) royalties on net sales of licensed products. Accordingly, the transaction price is generally comprised of a fixed fee due at contract inception and variable consideration in the form of pass through costs and milestone payments due upon the achievement of specified events and tiered royalties earned when customers recognize net sales of licensed products. The Company measures the transaction price based on the amount of consideration to which it expects to be entitled in exchange for transferring the promised goods and/or services to the customer. The Company utilizes the “most likely amount” method to estimate the amount of variable consideration, to predict the amount of consideration to which it will be entitled for its one open contract. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Milestone payments that are not within the control of the Company or the licensee, such as those dependent upon receipt of regulatory approval, are not considered to be probable of achievement until the triggering event occurs. At the end of each reporting period, the Company reevaluates the probability of achievement of each milestone and any related constraint, and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and net loss in the period of adjustment. For arrangements that include sales-based royalties, including milestone payments based upon the achievement of a certain level of product sales, the Company recognizes revenue upon the later of: (i) when the related sales occur or (ii) when the performance obligation to which some or all of the payment has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any development, regulatory or commercial milestones or royalty revenue resulting from any of its collaboration arrangements. Consideration that would be received for optional goods and/or services is excluded from the transaction price at contract inception. The Company allocates the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis, when applicable. However, certain components of variable consideration are allocated specifically to one or more particular performance obligations in a contact to the extent both of the following criteria are met: (i) the terms of the payment relate specifically to the efforts to satisfy the performance obligation or transfer the distinct good or service and (ii) allocating the variable amount of consideration entirely to the performance obligation or the distinct good or service is consistent with the allocation objective of the standard whereby the amount allocated depicts the amount of consideration to which the entity expects to be entitled in exchange for transferring the promised goods or services. The Company develops assumptions that require judgment to determine the standalone selling price for each performance obligation identified in each contract. The key assumptions utilized in determining the standalone selling price for each performance obligation may include forecasted revenues, development timelines, estimated research and development costs, discount rates, likelihood of exercise and probabilities of technical and regulatory success. Revenue is recognized based on the amount of the transaction price that is allocated to each respective performance obligation when or as the performance obligation is satisfied by transferring a promised good and/or service to the customer. For performance obligations that are satisfied over time, the Company recognizes revenue by measuring the progress toward complete satisfaction of the performance obligation using a single method of measuring progress which depicts the performance in transferring control of the associated goods and/or services to the customer. The Company uses input methods to measure the progress toward the complete satisfaction of performance obligations satisfied over time. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenue and net loss in the period of adjustment. The Company measures progress toward satisfaction of the performance obligation over time as effort is expended. Collaboration Agreement with LG Chem On November 6, 2018, the Company entered into a collaboration agreement (the “LG Chem Collaboration Agreement”) with LG Chem Ltd. (“LG Chem”) related to the development of the Company’s Immuno-STATs focused in the field of oncology. Pursuant to the LG Chem Collaboration Agreement, the Company granted LG Chem an exclusive license to develop, manufacture and commercialize the Company’s lead product, CUE-101, as well as Immuno-STATs that target T cells against two additional cancer antigens, in certain Asian countries (collectively, the “LG Chem Territory”). On April 30, 2021, LG Chem’s option pursuant to the Global License and Collaboration Agreement entered into between the Company and LG Chem on December 18, 2019 and as amended on November 5, 2020 (the "Global License and Collaboration Agreement"), expired, and accordingly the Company no longer has any material obligations under the Global License and Collaboration Agreement. In June 2021, after ongoing discussions regarding the selection of the second of the two additional cancer antigens, LG Chem and the Company agreed to let the selection period expire without a second antigen being selected. The Company retains rights to develop and commercialize all assets included in the LG Chem Collaboration Agreement in the United States and in global markets outside of the LG Chem Territory. In exchange for the licenses and other rights granted to LG Chem under the LG Chem Collaboration Agreement, LG Chem made a $ 5.0 million equity investment in common stock of the Company and a $ 5.0 million nonrefundable up-front cash payment. The Company is also eligible to receive up to an additional $ 400.0 million in research, development, regulatory and sales milestones. In addition, the LG Chem Collaboration Agreement also provides that LG Chem will pay the Company tiered single-digit percentage royalties on net sales of commercialized drug product candidates in the LG Chem Territory. On May 16, 2019, LG Chem paid the Company a $ 2.5 million milestone payment for the U.S. Food and Drug Administration’s (“FDA”) acceptance of the investigational new drug application (“IND”) for the Company’s lead drug product candidate, CUE-101, pursuant to the LG Chem Collaboration Agreement. The $ 2.5 million milestone payment was recorded as a contract liability upon receipt of payment as it requires deferral of revenue recognition to a future period until the Company performs its obligations under the arrangement. Of the $ 2.5 million milestone payment, approximately $ 412,500 was recognized as tax withholding, shown as income tax expense on the consolidated statement of operations and other comprehensive loss. On December 7, 2020, the Company earned a $ 1.25 million milestone payment on the selection of a pre-clinical candidate pursuant to the LG Chem Collaboration Agreement. The $ 1.25 million milestone payment was recorded as a contract liability upon receipt. Revenue related to this milestone payment was recognized by the Company pursuant to the Company’s revenue recognition policy in relation to the performance of its obligations related to the development of this pre-clinical candidate. Of the $ 1.25 million milestone payment, approximately $ 206,250 was withheld as payment of foreign tax withholding and shown as income tax expense on the consolidated statement of operations and other comprehensive loss. On November 23, 2021 the Company earned a $ 3 million milestone payment for the selection of a clinical product candidate in partnership with LG Chem. The $ 3 million milestone payment was recorded as a contract liability upon receipt. Revenue related to this milestone payment was recognized by the Company pursuant to the Company’s revenue recognition policy in relation to the performance of its obligations related to the development of this preclinical candidate. Of the $ 3 million milestone payment, approximately $ 495,000 was withheld as payment of foreign tax withholding and shown as income tax expense on the consolidated statements of operations and comprehensive loss. Cash was collected in relation to this milestone payment in February 2022. Aside from the $ 6.75 million in milestone payments earned to date, the Company does not believe that any variable consideration should be included in the transaction price as of June 30, 2023. Such assessment considered the application of the constraint to ensure that estimates of variable consideration would be included in the transaction price only to the extent the Company had a high degree of confidence that revenue would not be reversed in a subsequent reporting period. The Company will re-evaluate the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as other changes in circumstances occur. For the three months ended June 30, 2023 and 2022, the Company recognized revenue of approximately $ 29,000 and approximately $ 26,000 , respectively, related to the LG Chem Collaboration Agreement. For the six months ended June 30, 2023 and 2022, the Company recognized revenue of approximately $ 66,000 and approximately $ 1,026,000 , respectively, related to the LG Chem Collaboration Agreement. The Company did not record short or long-term research and development liabilities on its balance sheet dated June 30, 2023 and December 31, 2022 as the performance obligation was met and completed. Research and development cost sharing provisions under the agreement expired on March 31, 2022. Collaboration and Option Agreement with Ono On February 22, 2023, the Company entered into a strategic collaboration agreement (the "Ono Collaboration and Option Agreement") with Ono Pharmaceutical Co., Ltd. ("Ono") to further develop CUE-401 a nd provide dedicated resources and capabilities to help advance CUE-401 toward the clinic. Under the terms of the Ono Collaboration and Option Agreement, Ono paid the Company an upfront payment and agreed to fully fund all research activities related to CUE-401 through a specified option period. During this option period, the Company will be responsible for the research and development of CUE-401. Upon Ono’s exercise of its option to license CUE-401, the Company will receive an option exercise payment and be eligible for development and commercial milestone payments up to an aggregate of approximately $ 220 million, as well as tiered royalties on sales. Upon any such exercise, Ono will receive worldwide rights to develop and commercialize CUE-401, with the Company retaining a 50 % co-development and co-commercialization right in the United States. Under the terms of the Ono Collaboration and Option Agreement, the Company will perform research activities related to CUE-401 through a specified option period of 24 months (the “Research Term”). During this Research Term, the Company will be responsible for the execution of scientific investigation, nonclinical, preclinical, and clinical drug research and development activities designed to progress CUE-401 toward a potential IND and regulatory approval (such activities, collectively referred to as “R&D”). Ono is responsible for the funding of R&D activities performed by the Company. Per the agreement, as consideration for the R&D activities performed by the Company, Ono (i) made a one-time, non-refundable, non-creditable upfront payment of $ 3.0 million to the Company and (ii) will reimburse the Company for all costs incurred in conducting research, including (a) pass through costs from third party contractors and (b) full time employee salaries capped at $ 2.1 million in the first 18 months of the Research Term. The term of the Ono Collaboration and Option Agreement extends until the expiration of the Research Term which cannot exceed a 24-month period. The Company has forecasted that it will be able to complete the R&D activities in 18 months based on the initial research and development plans it has established. The Company received the $ 3.0 million upfront payment in March 2023. Aside from the $ 3.0 million upfront payment and funding related to pass through costs, the Company does not believe that any variable consideration should be included in the transaction price as of June 30, 2023. Such assessment considered the application of the constraint to ensure that estimates of variable consideration would be included in the transaction price only to the extent the Company had a high degree of confidence that revenue would not be reversed in a subsequent reporting period. The Company will re-evaluate the transaction price, including the estimated variable consideration included in the transaction price and all constrained amounts, in each reporting period and as other changes in circumstances occur. For the three months ended June 30, 2023 and 2022, the Company recognized revenue of approximately $ 1,353,000 and $ 0 , respectively, related to the Ono Collaboration and Option Agreement. For the six months ended June 30, 2023 and 2022, the Company recognized revenue of approximately $ 1,504,000 and $ 0 , respectively, related to the Ono Collaboration and Option Agreement. The Company recorded short and long-term research and development liabilities on its balance sheet dated June 30, 2023 , of approximately $ 2,547,000 and $ 136,000 , respectively. The Company did not recognize short or long-term research and development liabilities on its balance sheet as of December 31, 2022, as the agreement was executed in February 2023. Capitalization of Contract Costs The Company considered the capitalization of contract costs under the guidance in ASC 340-40, Other Assets and Deferred Costs: Contracts with Customers . As it related to the LG Chem Collaboration Agreement, the Company capitalized license expenses of approximately $ 908,000 as of June 30, 2023 , paid to Einstein pursuant to the Einstein License Agreement which requires the Company to pay a percentage of sublicenses related to the Company’s patent rights for components of its core technology that is licensed from Einstein. This amount is comprised of approximately $ 438,000 of capitalized license expenses related to the up-front payment received from LG Chem in December 2018, approximately $ 313,000 in capitalized license expenses related to the milestone payment received in June 2019, and approximately $ 157,000 in capitalized license expenses related to the milestone payment received in December 2020, net of accumulated amortization on all capitalized license expenses of approximately $ 908,000 . As of June 30, 2023 and December 31, 2022, no capitalized license expenses net of accumulated amortization were included in prepaid expenses and other short-term assets related to the LG Chem Collaboration Agreement. |

Amortization of leasehold improvements is provided using the straight-line method over the shorter of the lease term or the useful life of the underlying assets. Depreciation of property and equipment is provided using the straight-line method over the following estimated useful lives: Laboratory equipment 5 years Computer and office equipment 3 years Furniture and fixtures 3 - 8 years The Company recognizes depreciation and amortization expense in general and administrative expenses and in research and development expenses in the Company’s consolidated statements of operations and comprehensive loss, depending on how each category of property and equipment is utilized in the Company’s business activities. |
Trademark | Trademark Trademark consists of the Company’s right, title and interest to the CUE BIOLOGICS Mark, and any derivative mark incorporating CUE, throughout the world, together with all associated goodwill and common law rights appurtenant thereto, including, but not limited to, any right, title and interest in any corporate name, company name, business, name, trade name, dba, domain name, or other source identifier incorporating CUE. The Company has classified the trademark as a component of other long-term assets, having a useful life of 15 years. The Company evaluates the status of this intangible asset for amortization and impairment at each quarter end and year end reporting date.

Debt issuance costs are amortized using the effective interest rate method over the term of the loan. Amortization of deferred debt issuance costs are included in interest expense in the consolidated statements of operations and other comprehensive loss. |
Revenue Recognition | Revenue Recognition The Company recognizes collaboration revenue under certain of the Company’s license and collaboration agreements that are within the scope of Accounting Standards Codification (“ASC”), Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company’s contracts with customers typically include promises related to licenses to intellectual property and research and development services. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. Accordingly, the transaction price is generally comprised of a fixed fee due at contract inception and variable consideration in the form of milestone payments due upon the achievement of specified events and tiered royalties earned when customers recognize net sales of licensed products. The Company measures the transaction price based on the amount of consideration to which it expects to be entitled in exchange for transferring the promised goods and/or services to the customer. The Company utilizes the “most likely amount” method to estimate the amount of variable consideration, to predict the amount of consideration to which it will be entitled for its one open contract. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. At the inception of each arrangement that includes development and regulatory milestone payments, the Company evaluates whether the associated event is considered probable of achievement and estimates the amount to be included in the transaction price using the expected value method. |
Research and Development Expenses | Research and Development Expenses Research and development expenses consist primarily of compensation costs, fees paid to consultants, outside service providers and organizations (including research institutes at universities), facility costs, and development and clinical trial costs with respect to the Company’s drug product candidates. Research and development expenses incurred under contracts are expensed ratably over the life of the underlying contracts, unless the achievement of milestones, the completion of contracted work, or other information indicates that a different pattern of performance is more appropriate. Other research and development expenses are charged to operations as incurred. Nonrefundable advance payments are recognized as an expense as the related services are performed. The Company evaluates whether it expects the services to be rendered at each quarter end and year end reporting date. If the Company does not expect the services to be rendered, the advance payment is charged to expense. Nonrefundable advance payments for research and development services are included in prepaid and other current assets on the balance sheet. To the extent that a nonrefundable advance payment is for contracted services to be performed within 12 months from the reporting date, such advance is included in current assets; otherwise, such advance is included in non-current assets. The Company evaluates the status of its research and development agreements and contracts, and the carrying amount of the related assets and liabilities, at each quarter end and year end reporting date, and adjusts the carrying amounts and their classification on the balance sheet as appropriate. |
Patent Expenses | Patent Expenses The Company is the exclusive worldwide licensee of, and has patent applications pending for, numerous domestic and foreign patents. Due to the significant uncertainty associated with the successful development of one or more commercially viable drug product candidates based on the Company’s research efforts and any related patent applications, all patent costs, including patent-related legal fees, filing fees and other costs are charged to general and administrative expense as incurred. For the three and six months ended June 30, 2023 , patent expenses were approximately $ 514,000 and $ 1,146,000 , respectively. For the three and six months ended June 30, 2022, patent expenses were $ 564,000 and $ 1,230,000 , respectively. |
Licensing Fees and Costs | Licensing Fees and Costs Licensing fees and costs consist primarily of costs relating to the acquisition of the Company’s license agreement (the “Einstein License Agreement”) with the Albert Einstein College of Medicine (“Einstein”), including related royalties, maintenance fees, milestone payments and product development costs. Licensing fees and costs are charged to research and development expense as incurred. |
Long-Lived Assets | Long-Lived Assets The Company reviews long-lived assets, consisting of property and equipment, for impairment at each fiscal year end or when events or changes in circumstances indicate the carrying value of these assets may exceed their current fair values. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the assets. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated. The Company has not historically recorded any impairment to its long-lived assets. In the future, if events or market conditions affect the estimated fair value to the extent that a long-lived asset is impaired, the Company will adjust the carrying value of these long-lived assets in the period in which the impairment occurs. |
Leases | Leases The Company accounts for leases under ASC 842 Leases, which requires a lessee to record a right-of-use asset and a corresponding lease liability for most lease arrangements on the balance sheet. Under the standard, disclosure of key information about leasing arrangements to assist users of the financial statements with assessing the amount, timing and uncertainty of cash flows arising from leases are required. |
Stock-Based Compensation | Stock-Based Compensation The Company periodically issues stock-based awards to officers, directors, employees, Scientific and Clinical Advisory Board members and consultants for services rendered. Such issuances vest and expire according to terms established at the issuance date. Stock-based payments to officers, directors, employees, Scientific and Clinical Advisory Board members and consultants, including grants of employee stock options, are recognized in the financial statements based on their grant date fair values. Stock option grants, which are generally time-vested, are measured at the grant date fair value and charged to operations on a straight-line basis over the service period, which generally approximates the vesting term. The Company also grants performance-based awards periodically to officers of the Company. The Company recognizes compensation costs related to performance awards over the requisite service period if and when the Company concludes that it is probable that the performance condition will be achieved. The fair value of stock options and restricted stock units is determined utilizing the Black-Scholes option-pricing model, which is affected by several variables, including the risk-free interest rate, the expected dividend yield, the life of the equity award, the exercise price of the stock option as compared to the fair value of the common stock on the grant date, and the estimated volatility of the common stock over the term of the equity award. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Until the Company has established a trading history for its common stock that approximates the expected term of the options, estimated volatility is based on the average historical volatilities of comparable public companies in a similar industry. The expected dividend yield is based on the current yield at the grant date; the Company has never declared or paid dividends and has no plans to do so for the foreseeable future. As permitted by Staff Accounting Bulletin No. 107, due to the Company’s limited trading history and option activity, management utilizes the simplified method to estimate the expected term of options at the date of grant. The exercise price is determined based on the fair value of our common stock at the date of grant. The Company accounts for forfeitures as they occur. The Company recognizes the fair value of stock-based compensation in general and administrative expenses and in research and development expenses in the Company’s consolidated statements of operations and comprehensive loss, depending on the type of services provided by the recipient of the equity award. |
Comprehensive Income (Loss) | Comprehensive Income (Loss) Components of comprehensive income or loss, including net income or loss, are reported in the financial statements in the period in which they are recognized. Other comprehensive income or loss is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Net income (loss) and other comprehensive income (loss) are reported net of any related tax effect to arrive at comprehensive income (loss). Comprehensive income (loss) includes net income (loss) as well as changes in stockholders’ equity that result from transactions and economic events other than those with stockholders. The Company’s only element of other comprehensive income (loss) in periods presented was unrealized gain or loss on available-for-sale securities. |
Earnings (Loss) Per Share | Earnings (Loss) Per Share The Company’s computation of earnings (loss) per share (“EPS”) for the respective periods includes basic and diluted EPS. Basic EPS is measured as the income (loss) attributable to common stockholders divided by the weighted average number of common shares outstanding for the period. Diluted EPS is similar to basic EPS but presents the dilutive effect on a per share basis of potential common shares that would result from the exercise of outstanding stock options and warrants as if they had been exercised at the beginning of the periods presented, or issuance date, if later. Potential common shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. Basic and diluted loss per common share is the same for all periods presented because all outstanding stock options and warrants are anti-dilutive. Per ASC 260-10-45-13, shares issuable for little to no consideration should be included in the number of outstanding shares used for basic EPS. The FASB proposed that warrants or options exercisable for little to no cost (sometimes referred to as “penny warrants”) be included in the denominator of basic EPS (and therefore diluted EPS) once there were no further vesting conditions or contingencies associated with them. The Company included 1,531,440 pre-funded warrants in the denominator of basic EPS at June 30, 2023. At June 30, 2023 and 2022, the Company excluded the outstanding securities summarized below, which entitle the holders thereof to acquire shares of common stock, from its calculation of earnings per share, as their effect would have been anti-dilutive. June 30, 2023 2022 Common stock warrants 10,719,846 789,358 Common stock options 7,104,675 6,306,354 Nonvested restricted stock units - 6,667 Total 17,824,521 7,102,379 |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The authoritative guidance with respect to fair value established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories, as presented below. Level 1. Observable inputs such as quoted prices in active markets for an identical asset or liability that the Company has the ability to access as of the measurement date. Financial assets and liabilities utilizing Level 1 inputs include active exchange-traded securities and exchange-based derivatives. Level 2. Inputs, other than quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include fixed income securities, non-exchange-based derivatives, mutual funds, and fair-value hedges. Level 3. Unobservable inputs in which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. Financial assets and liabilities utilizing Level 3 inputs include infrequently traded non-exchange-based derivatives and commingled investment funds and are measured using present value pricing models. The Company determines the level in the fair value hierarchy within which each fair value measurement falls in its entirety, based on the lowest level input that is significant to the fair value measurement in its entirety. In determining the appropriate levels, the Company performs an analysis of the assets and liabilities at each reporting period end. The Company had approximately $ 52,901,000 in cash equivalents and approximately $ 4,988,000 in short-term marketable securities that were measured and recorded at fair value on the Company’s balance sheet as of June 30, 2023 . The Company had approximately $ 45,423,000 in cash equivalents and approximately $ 24,675,000 in short-term marketable securities that were measured and recorded at fair value on the Company’s balance sheet at December 31, 2022. The carrying value of financial instruments (consisting of cash, a certificate of deposit, accounts payable, accrued compensation and accrued expenses) is considered to be representative of their respective fair values due to the short-term nature of those instruments. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update ("ASU") No. 2016-13 , Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326) (CECL). The new standard requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new standard is effective for annual reporting periods beginning after December 15, 2022, including interim reporting periods within each annual reporting period for smaller reporting companies. T he Company adopted ASU No. 2016-13 but there was no financial impact to the Company’s consolidated financial statements for the year ended December 31, 2022 or for the six months ended June 30, 2023. Management does not believe that any other recently issued, but not yet effective, authoritative guidance, if currently adopted, would have a material impact on the Company’s financial statement presentation or disclosures. |
