General And Liquidity [Abstract] | |
General And Liquidity | Note 1. General and Liquidity Cassava Sciences, Inc. (the “Company”) discovers and develops proprietary pharmaceutical product candidates that may offer significant improvements to patients and healthcare professionals. The Company generally focuses its discovery and product development efforts on disorders of the nervous system. The accompanying unaudited condensed financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, the condensed financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management of the Company, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for any other interim period or for the year 2021 . For further information, refer to the financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Coronavirus Disease 2019 (COVID-19) The widespread outbreak of a novel infectious disease called Coronavirus Disease 2019, or COVID-19, has not significantly impacted the Company’s operations or financial condition as of August 4, 2021. However, this pandemic has created a dynamic and uncertain situation in the national economy. The Company continues to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on its operations and financial condition. The scope of pandemic is unprecedented and its long-term impact on the Company’s operations and financial condition cannot be reasonably estimated at this time. Liquidity The Company has incurred significant net losses and negative cash flows since inception, and as a result has an accumulated deficit of $ 183.6 million at June 30, 2021. The Company expects its cash requirements to be significant in the future. The amount and timing of the Company’s future cash requirements will depend on regulatory and market acceptance of its product candidates and the resources it devotes to researching and developing, formulating, manufacturing, commercializing and supporting its products. The Company may seek additional funding through public or private financing in the future, if such funding is available and on terms acceptable to the Company. There are no assurances that additional financing will be available on favorable terms, or at all. However, management believes that the current working capital position will be sufficient to meet the Company’s working capital needs for at least the next 12 months. |

Significant Accounting Policies [Abstract] | |
Significant Accounting Policies | Note 2. Significant Accounting Policies Use of Estimates The Company makes estimates and assumptions in preparing its condensed financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to manufacturing agreements and research collaborations. Actual results could differ from these estimates and assumptions. Cash and Cash Equivalents and Concentration of Credit Risk The Company invests in cash and cash equivalents. The Company considers highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered cash equivalents include money market accounts and funds, certificates of deposits, and U.S. Treasury securities. The Company maintains its cash and cash equivalents at one financial institution. Fair Value Measurements The Company recognizes financial instruments in accordance with the authoritative guidance on fair value measurements and disclosures for financial assets and liabilities. This guidance defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. The guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1 includes quoted prices in active markets. Level 2 includes significant observable inputs, such as quoted prices for identical or similar securities, or other inputs that are observable and can be corroborated by observable market data for similar securities. The Company uses market pricing and other observable market inputs obtained from third-party providers. It uses the bid price to establish fair value where a bid price is available. The Company does not have any financial instruments where the fair value is based on Level 2 inputs. Level 3 includes unobservable inputs that are supported by little or no market activity. The Company does not have any financial instruments where the fair value is based on Level 3 inputs. If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The fair value of cash and cash equivalents was based on Level 1 inputs at June 30, 2021 and December 31, 2020. Proceeds from Grants During the three months ended June 30, 2021 and 2020, the Company received reimbursements totaling $ 0.9 million and $ 1.1 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the six months ended June 30, 2021 and 2020, the Company received reimbursements totaling $ 1.5 million and $ 2.4 million pursuant to NIH research grants, respectively. The Company records the proceeds from these grants as reductions to its research and development expenses. Stock-based Compensation The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years . The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria. Net Loss per Share The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options and warrants. There is no difference between the Company’s net loss and comprehensive loss. The Company included the following in the calculation of basic and diluted net loss per share (in thousands, except per share data): Three months ended Six months ended June 30, June 30, 2021 2020 2021 2020 Numerator: Net loss $ ( 5,125 ) $ ( 1,136 ) $ ( 8,651 ) $ ( 2,286 ) Denominator: Shares used in computing net loss per share, basic and diluted 39,953 24,779 38,843 24,630 Net loss per share, basic and diluted $ ( 0.13 ) $ ( 0.05 ) $ ( 0.22 ) $ ( 0.09 ) Dilutive common stock options excluded from net loss per share, diluted 2,129 2,294 2,163 2,177 Common stock warrants excluded from net loss per share, diluted — 1,427 — 1,427 The Company excluded common stock options and warrants outstanding from the calculation of net loss per share, diluted, because the effect of including options and warrants outstanding would have been anti - dilutive. Fair Value of Financial Instruments Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments. Research Contract Costs and Accruals The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs. Incentive Bonus Plan In 2020, the Company established the 2020 Cash Incentive Bonus Plan (the “Plan”) to incentivize Plan participants. Awards under the Plan are accounted for as liability awards under Accounting Standards Codification (ASC) 718 “ Stock-based Compensation ”. The fair value of each potential Plan award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each Plan award, when a Performance Condition is considered probable of being met. See Note 8 for further discussion of the Plan. Leases The Company recognizes assets and liabilities that arise from leases. For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments during the lease term, in the condensed balance sheets. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities. As the Company`s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Income Taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance. The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s condensed financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense. |

Net proceeds of the offering were approximately $ 189.8 million after deducting offering expenses. At-the-Market Common Stock Offering In March 2020, the Company established an at-the-market offering program (“ATM”) to sell, from time to time, shares of Company common stock having an aggregate offering price of up to $ 100 million in transactions pursuant to a shelf registration statement that was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on May 5, 2020 . The Company is obligated to pay a commission of 3.0 % of the gross proceeds from the sale of shares of common stock in the offering. The Company is not obligated to sell any shares in the offering. There were no common stock sales under the ATM during the three and six months ended June 30, 2021 and 2020. Common Stock Warrants In August 2018, the Company issued warrants to purchase up to an aggregate of 9.1 million shares of its common stock in conjunction with an offering of its common stock. The Company did no t receive any proceeds from exercise of common stock warrants during the three months ended June 30, 2021. During the three months ended June 30, 2020, the Company received proceeds of $ 0.2 million from the exercise of 0.2 million shares pursuant to warrants. During the six months ended June 30, 2021, the Company received proceeds of $ 0.7 million from the exercise of 0.6 million shares pursuant to warrants. During the six months ended June 30, 2020, the Company received proceeds of $ 3.8 million from the exercise of 3.1 million shares pursuant to warrants. There were no remaining common stock warrants outstanding as of June 30, 2021. Stock Option and Performance Award Activity in 2021 During the six months ended June 30, 2021, stock options and unvested Performance Awards outstanding under the Company’s stock option plans changed as follows: Stock Options Performance Awards Outstanding as of December 31, 2020 2,817,504 138,055 Options granted 85,000 — Options exercised ( 234,994 ) — Options forfeited/canceled ( 9,338 ) — Outstanding as of June 30, 2021 2,658,172 138,055 The weighted average exercise price of options outstanding at June 30, 2021 was $ 11.40 . As outstanding options vest over the current remaining vesting period of 2.2 years, the Company expects to recognize stock-based compensation expense of $ 6.7 million. If and when outstanding Performance Awards vest, the Company will recognize stock-based compensation expense of $ 2.3 million over the implicit service period. During the three months ended June 30, 2021, there were 71,596 stock options exercised. Of the stock options exercised, 68,356 stock options were net settled in satisfaction of the exercise price, with no cash proceeds received. Cash proceeds to the Company totaled $ 3,000 during the three months ended June 30, 2021. During the six months ended June 30, 2021, there were 234,994 stock options exercised. Of the stock options exercised, 98,739 stock options were net settled in satisfaction of the exercise price, with no cash proceeds received. Cash proceeds to the Company totaled $ 1,749,000 during the six months ended June 30, 2021. There were no stock options exercised during the three and six months ended June 30, 2020. Subsequent to June 30, 2021, there were 2,801 stock options exercised for cash proceeds of $ 57,000 . Stock-based Compensation Expense in 2021 During the three and six months ended June 30, 2021 and 2020, the Company’s stock-based compensation expense was as follows (in thousands): Three months ended Six months ended June 30, June 30, 2021 2020 2021 2020 Research and development $ 295 $ 111 $ 415 $ 226 General and administrative 120 141 250 296 Total stock-based compensation expense $ 415 $ 252 $ 665 $ 522 2018 Equity Incentive Plan In January 2018, the Company’s Board of Directors (the “Board”) approved the Company’s 2018 Omnibus Incentive Plan (the “2018 Plan”). The Board or a designated committee of the Board is responsible for administration of the 2018 Plan and determines the terms and conditions of each option granted, consistent with the terms of the 2018 Plan. The Company’s employees, directors, and consultants are eligible to receive awards under the 2018 Plan, including grants of stock options and Performance Awards. Share-based awards generally expire 10 years from the date of grant. The 2018 Plan provides for issuance of up to 1,000,000 shares of common stock, par value $ 0.001 per share, subject to adjustment as provided in the 2018 Plan. When stock options or Performance Awards are exercised net of the exercise price and taxes, the number of shares of stock issued is reduced by the number of shares equal to the amount of taxes owed by the award recipient and that number of shares are cancelled. The Company then uses its cash to pay tax authorities the amount of statutory taxes owed by and on behalf of the award recipient. |

Cash Incentive Bonus Plan [Abstract] | |
2020 Cash Incentive Bonus Plan | Note 8. 2020 Cash Incentive Bonus Plan On August 26, 2020, the Board approved the Plan. The Plan was established to promote the long-term success of the Company by creating an “at-risk” cash bonus program that rewards Plan participants with additional cash compensation in lockstep with significant increases in the Company’s market capitalization. The Plan is considered “at-risk” because Plan participants will not receive a cash bonus unless the Company’s market capitalization increases significantly and certain other conditions specified in the Plan are met. Specifically, Plan participants will not be paid any cash bonuses unless (1) the Company completes a merger or acquisition transaction that constitutes a sale of ownership of the Company or its assets (a Merger Transaction) or (2) the Compensation Committee of the Board (the Compensation Committee) determines the Company has sufficient cash on hand, as defined in the Plan. Because of the inherent discretion and uncertainty regarding these requirements, the Company has concluded that a Plan grant date has not occurred as of June 30, 2021. Plan participants will be paid all earned cash bonuses in the event of a Merger Transaction. The Company’s market capitalization for purposes of the Plan is determined based on either (1) the Company’s closing price of one share on the Nasdaq Capital Market multiplied by the total issued and outstanding shares and options to purchase shares of the Company, or (2) the aggregate consideration payable to security holders of the Company in a Merger Transaction. This constitutes a market condition under applicable accounting guidance. The Plan triggers a potential cash bonus each time the Company’s market capitalization increases significantly, up to a maximum $ 5 billion in market capitalization. The Plan specifies 14 incremental amounts between $ 200 million and $ 5 billion (each increment, a “Valuation Milestone”). Each Valuation Milestone triggers a potential cash bonus award in a pre-set amount defined in the Plan. Each Valuation Milestone must be achieved and maintained for no less than 20 consecutive trading days for Plan participants to be eligible for a potential cash bonus award. Approximately 58 % of each cash bonus award associated with a Valuation Milestone is subject to adjustment and approval by the Compensation Committee. Any amounts not awarded by the Compensation Committee are no longer available for distribution. If the Company were to exceed a $5 billion market capitalization for no less than 20 consecutive trading days, all Valuation Milestones would be deemed achieved, in which case cash bonus awards would range from a minimum of $ 139.1 million up to a hypothetical maximum of $ 322.3 million. Payment of cash bonuses is deferred until such time as (1) the Company completes a Merger Transaction, or (2) the Compensation Committee determines the Company has sufficient cash on hand to render payment (each, a “Performance Condition”), neither of which may ever occur. Accordingly, there can be no assurance that Plan participants will ever be paid a cash bonus that is awarded under the Plan, even if the Company’s market capitalization increases significantly. The Plan is accounted for as a liability award. The fair value of each Valuation Milestone award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each of the 14 Valuation Milestones, when a Performance Condition is considered probable of being met. On October 13, 2020, the Company achieved the first Valuation Milestone. Subsequently, the Compensation Committee approved a potential cash bonus award of $ 7.3 million in total for all Plan participants, subject to future satisfaction of a Performance Condition. During the six months ended June 30, 2021, the Company achieved 10 Valuation Milestones triggering potential Company obligations to all Plan participants from a minimum of $ 81.0 million up to a hypothetical maximum of $ 195.0 million, to be determined by the Compensation Committee. However, no compensation expense has been recorded since no grant date has occurred and no Performance Conditions are considered probable of being met. There is no continuing service requirement for Plan participants once the Compensation Committee approves a cash bonus award. Subsequent to June 30, 2021, the Company achieved one additional Valuation Milestone triggering potential Company obligations to all Plan participants from a minimum of $ 12.7 million up to a hypothetical maximum of $ 30.0 million, to be determined by the Compensation Committee and contingent upon future satisfaction of a Performance Condition. No actual cash payments were authorized or made to participants under the Plan through June 30, 2021. |

Significant Accounting Policies [Abstract] | |
Use Of Estimates | Use of Estimates The Company makes estimates and assumptions in preparing its condensed financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amount of revenue earned and expenses incurred during the reporting period. The Company evaluates its estimates on an ongoing basis, including those estimates related to manufacturing agreements and research collaborations. Actual results could differ from these estimates and assumptions. |
Cash And Cash Equivalents And Concentration Of Credit Risk | Cash and Cash Equivalents and Concentration of Credit Risk The Company invests in cash and cash equivalents. The Company considers highly liquid financial instruments with original maturities of three months or less to be cash equivalents. Highly liquid investments that are considered cash equivalents include money market accounts and funds, certificates of deposits, and U.S. Treasury securities. The Company maintains its cash and cash equivalents at one financial institution. |
Fair Value Measurements | Fair Value Measurements The Company recognizes financial instruments in accordance with the authoritative guidance on fair value measurements and disclosures for financial assets and liabilities. This guidance defines fair value, establishes a framework for measuring fair value in accordance with GAAP, and expands disclosures about fair value measurements. The guidance also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1 includes quoted prices in active markets. Level 2 includes significant observable inputs, such as quoted prices for identical or similar securities, or other inputs that are observable and can be corroborated by observable market data for similar securities. The Company uses market pricing and other observable market inputs obtained from third-party providers. It uses the bid price to establish fair value where a bid price is available. The Company does not have any financial instruments where the fair value is based on Level 2 inputs. Level 3 includes unobservable inputs that are supported by little or no market activity. The Company does not have any financial instruments where the fair value is based on Level 3 inputs. If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. The fair value of cash and cash equivalents was based on Level 1 inputs at June 30, 2021 and December 31, 2020. |
Proceeds From Grants | Proceeds from Grants During the three months ended June 30, 2021 and 2020, the Company received reimbursements totaling $ 0.9 million and $ 1.1 million pursuant to National Institutes of Health (“NIH”) research grants, respectively. During the six months ended June 30, 2021 and 2020, the Company received reimbursements totaling $ 1.5 million and $ 2.4 million pursuant to NIH research grants, respectively. The Company records the proceeds from these grants as reductions to its research and development expenses. |
Stock-Based Compensation | Stock-based Compensation The Company recognizes non-cash expense for the fair value of all stock options and other share-based awards. The Company uses the Black-Scholes option valuation model (“Black-Scholes”) to calculate the fair value of stock options, using the single-option award approach and straight-line attribution method. For all options granted, it recognizes the resulting fair value as expense on a straight-line basis over the vesting period of each respective stock option, generally four years . The Company has granted share-based awards that vest upon achievement of certain performance criteria (“Performance Awards”). The Company multiplies the number of Performance Awards by the fair value of its common stock on the date of grant to calculate the fair value of each award. It estimates an implicit service period for achieving performance criteria for each award. The Company recognizes the resulting fair value as expense over the implicit service period when it concludes that achieving the performance criteria is probable. It periodically reviews and updates as appropriate its estimates of implicit service periods and conclusions on achieving the performance criteria. Performance Awards vest and common stock is issued upon achievement of the performance criteria. |
Net Loss Per Share | Net Loss per Share The Company computes basic net loss per share on the basis of the weighted-average number of common shares outstanding for the reporting period. Diluted net loss per share is computed on the basis of the weighted-average number of common shares outstanding plus potential dilutive common shares outstanding using the treasury-stock method. Potential dilutive common shares consist of outstanding common stock options and warrants. There is no difference between the Company’s net loss and comprehensive loss. The Company included the following in the calculation of basic and diluted net loss per share (in thousands, except per share data): Three months ended Six months ended June 30, June 30, 2021 2020 2021 2020 Numerator: Net loss $ ( 5,125 ) $ ( 1,136 ) $ ( 8,651 ) $ ( 2,286 ) Denominator: Shares used in computing net loss per share, basic and diluted 39,953 24,779 38,843 24,630 Net loss per share, basic and diluted $ ( 0.13 ) $ ( 0.05 ) $ ( 0.22 ) $ ( 0.09 ) Dilutive common stock options excluded from net loss per share, diluted 2,129 2,294 2,163 2,177 Common stock warrants excluded from net loss per share, diluted — 1,427 — 1,427 The Company excluded common stock options and warrants outstanding from the calculation of net loss per share, diluted, because the effect of including options and warrants outstanding would have been anti - dilutive. |
Fair Value Of Financial Instruments | Fair Value of Financial Instruments Financial instruments include accounts payable and accrued liabilities. The estimated fair value of certain financial instruments may be determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop estimates of fair value; therefore, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange. The effect of using different market assumptions and/or estimation methodologies may be material to the estimated fair value amounts. The carrying amounts of accounts payable and accrued liabilities are at cost, which approximates fair value due to the short maturity of those instruments. |
Research Contract Costs And Accruals | Research Contract Costs and Accruals The Company has entered into various research and development contracts with research institutions and other third-party vendors. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company’s estimates. The Company’s historical accrual estimates have not been materially different from actual costs. |
Incentive Bonus Plan | Incentive Bonus Plan In 2020, the Company established the 2020 Cash Incentive Bonus Plan (the “Plan”) to incentivize Plan participants. Awards under the Plan are accounted for as liability awards under Accounting Standards Codification (ASC) 718 “ Stock-based Compensation ”. The fair value of each potential Plan award will be determined once a grant date occurs and will be remeasured each reporting period. Compensation expense associated with the Plan will be recognized over the expected achievement period for each Plan award, when a Performance Condition is considered probable of being met. See Note 8 for further discussion of the Plan. |
Leases | Leases The Company recognizes assets and liabilities that arise from leases. For operating leases, the Company is required to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments during the lease term, in the condensed balance sheets. The Company elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, the Company does not recognize right-of-use assets or lease liabilities. As the Company`s leases do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term. |
Income Taxes | Income Taxes The Company accounts for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax balances are adjusted to reflect tax rates based on currently enacted tax laws, which will be in effect in the years in which the temporary differences are expected to reverse. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating loss and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance. The Company accounts for uncertain tax positions in accordance with ASC 740, “Income Taxes”, which clarifies the accounting for uncertainty in tax positions. These provisions require recognition of the impact of a tax position in the Company’s condensed financial statements only if that position is more likely than not of being sustained upon examination by taxing authorities, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions will be reflected as a component of income tax expense. |
