Description Of The Business [Abstract] | |
Description Of The Business | 1. Description of the Business Pulse Biosciences, Inc. is a novel bioelectric medicine company committed to health innovation that improves and potentially extends the lives of patients. The Company is pursuing regulatory clearance to market its first product, its proprietary CellFX System. The Company ’s CellFX System utilizes its patented Nano-Pulse Stimulation™ (NPS™) technology to treat a variety of applications for which an optimal solution remains unfulfilled. NPS is a proprietary technology that delivers nano-second duration pulses of high amplitude electrical energy to non-thermally clear targeted cells while sparing adjacent non-cellular tissue. The cell-specific effects of NPS technology have been validated in a series of completed and ongoing clinical studies. The Company was incorporated in Nevada on May 19, 2014. On June 18, 2018, the Company reincorporated from the State of Nevada to the State of Delaware. The Company’s headquarters and manufacturing and research facility are located in Hayward, California. The Company’s activities are subject to significant risks and uncertainties, including the need for additional capital. The Company has not yet commenced any revenue-generating operations, does not have any cash flows from operations, and will need to raise additional capital to finance its operations. However, there can be no assurances that the Company will be able to obtain additional financing on acceptable terms and in the amounts necessary to fully fund its operating requirements. |

Summary Of Significant Accounting Policies [Abstract] | |
Summary Of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“Financial Statements”) have been prepared on a basis consistent with the Company’s December 31, 2018 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The results of operations for the three- and nine-month periods ended September 30, 2019 are not necessarily indicative of the results to be expected for the entire year or any future periods. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the Financial Statements and accompanying notes to the Financial Statements. Estimates include, but are not limited to, the valuation of cash equivalents and investments, the valuation and recognition of share-based compensation and the useful lives assigned to long-lived assets. The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. Recently Adopted Accounting Pronouncement During February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“Topic 842”), which amended prior accounting standards for leases. The Company adopted Topic 842 on January 1, 2019, using the transition method per ASU No. 2018-11 issued on July 2018 wherein entities were allowed to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC 840, Leases, and no retrospective adjustments were made to the comparative periods presented. The adoption of ASC 842 resulted in an increase to total assets and liabilities due to the recording of operating lease right-of-use assets (“ROU”) presented within other assets and operating lease liabilities of approximately $0.1 million as of January 1, 2019. The adoption did not materially impact the Company’s Consolidated Statement of Stockholders’ Equity or Cash Flows. Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three- and nine-month periods ended September 30, 2019, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, except for the adoption of ASU No. 2016-02, Leases , as of January 1, 2019. Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse Biosciences and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation. Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. 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 net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Nine-Month Periods Ended September 30, 2019 2018 Common stock warrants 213,485 213,485 Common stock options 3,545,491 2,858,387 Restricted stock units 111,305 222,606 Total 3,870,281 3,294,478 Reclassifications Certain items in prior period financial statements have been reclassified to conform to the presentation in the current period financial statements. Such reclassifications did not impact the Company's previously reported net loss or financial position. |

Fair Value Of Financial Instruments [Abstract] | |
Fair Value Of Financial Instruments | 3. 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 to 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 money market funds. 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 commercial paper, corporate bonds, and asset-backed securities. Level 3 - Unobservable inputs for which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. The Company did not classify any of its investments within Level 3 of the fair value hierarchy. The following table sets forth the fair value of the Company’s financial assets measured on a recurring basis as of September 30, 2019 and December 31, 2018, respectively (in thousands): September 30, 2019 December 31, 2018 Assets Classification Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Money market funds Cash and cash equivalents $ 5,912 $ — $ — $ 5,912 $ 50,703 $ — $ — $ 50,703 U.S. Treasury Securities Investments, cash and cash equivalents — 27,919 — 27,919 — 8,480 — 8,480 Total assets measured at fair value $ 5,912 $ 27,919 $ — $ 33,831 $ 50,703 $ 8,480 $ — $ 59,183 The Company did not have any financial liabilities measured on a recurring basis as of September 30, 2019 or December 31, 2018. During the nine-month period ended September 30, 2019, there were no transfers between Level 1, Level 2 or Level 3 assets or liabilities reported at fair value on a recurring basis, and the valuation techniques used did not change compared to the Company’s established practice. |

Stockholders' Equity And Stock-Based Compensation | 8. Stockholders’ Equity and Stock-Based Compensation Rights Offering On October 25, 2018, the Company commenced a rights offering pursuant to which stockholders of record as of November 19, 2018, were issued, at no charge, one subscription right for each share of common stock then outstanding. Each right entitled the holder to purchase 0.19860755 share of the Company’s common stock for $12.57 per share (the “Rights Offering”). Stockholders who exercised their rights in full were also permitted an over-subscription right to purchase additional shares of common stock that remained unsubscribed at the expiration of the Rights Offering, subject to the availability of shares and a pro rata allocation of shares among persons exercising the oversubscription right. Upon the closing of the Rights Offering on December 6, 2018, the Rights Offering was oversubscribed. A total of 3,581,148 shares of the Company’s common stock were issued and sold in the Rights Offering for net proceeds of approximately $44.8 million. Robert W. Duggan, the Company’s Chairman of the Board of Directors and the beneficial owner of approximately 35% of the Company’s outstanding common stock prior to the Rights Offering, participated in the Rights Offering and purchased an aggregate of 3,146,226 shares for an additional investment of approximately $39.5 million. Common Stock Warrants In connection with a private placement offering of the Company’s common stock, par value $0.001 per share in 2014, the Company issued warrants as compensation to the placement agent to purchase a total of 299,625 shares of its common stock at a price of $2.67 per share (the “Private Placement Warrants”). The Private Placement Warrants are exercisable for period of seven years. As of September 30, 2019, there were a total of 91,876 of Private Placement Warrants outstanding. In connection with the closing of the Company’s initial public offering in 2016, the Company issued warrants as compensation to its underwriters, as representatives of the underwriters of its initial public offering to purchase a total of 574,985 shares of its common stock at a price of $5.00 per share (“the IPO Warrants”). The IPO Warrants are exercisable for a period of five years. As of September 30, 2019, there were a total of 121,609 of the IPO Warrants outstanding. Equity Plans 2017 Equity Incentive Plan and 2017 Inducement Equity Incentive Plan The Board of Directors of the Company (the “Board”) previously adopted, and the Company’s stockholders approved, the Company’s 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan has a 10 -year term, and provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance units, and performance shares to employees, directors and consultants of the Company and any parent or subsidiary of the Company, as the Compensation Committee of the Board may determine. Subject to an annual evergreen increase and adjustment in the case of certain capitalization events, the Company initially reserved 1,500,000 shares of the Company’s common stock for issuance pursuant to awards under the 2017 Plan. In addition, shares remaining available under the Company’s 2015 Equity Incentive Plan, as amended (the “2015 Plan”), and shares reserved but not issued pursuant to outstanding equity awards that expire or terminate without being exercised or that are forfeited or repurchased by the Company will be added to the shares of common stock available for issuance under the 2017 Plan. The 2017 Plan is administered by the Board’s Compensation Committee. Effective January 1, 2019, the Company’s Board authorized an increase in the number of shares of common stock available under the 2017 Plan increased by 823, 716 shares pursuant to the evergreen provision of the 2017 Plan. Pursuant to the 2017 Plan, the 2019 share increase is determined based on the least of (i) 1,200,000 shares, (ii) 4% of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. As of September 30, 2019, 1,090,058 shares of common stock remained available for issuance under the 2017 Plan. During November 2017, the Board adopted the 2017 Inducement Equity Incentive Plan (the “Inducement Plan”) and reserved 1,000,000 shares of the Company’s common stock for issuance pursuant to equity awards granted under the Inducement Plan. The Inducement Plan was adopted without stockholder approval. The Inducement Plan has a 10 -year term, and provides for the grant of equity-based awards, including nonstatutory stock options, restricted stock units, restricted stock, stock appreciation rights, performance shares and performance units, and its terms are substantially similar to the 2017 Plan, including with respect to treatment of equity awards in the event of a “merger” or “change in control” as defined under the Inducement Plan. Options issued under the Inducement Plan may have a term up to ten years and have variable vesting provisions. New hire grants generally vest 25% annual starting upon the first anniversary of the grant. Equity-based awards issued under the Inducement Plan are only issuable to individuals not previously engaged as employees or non-employee directors of the Company prior to the Inducement Plan’s adoption date. As of September 30, 2019, there were 190,875 shares of common stock remained available for issuance under the Inducement Plan. 2017 Employee Stock Purchase Plan The Board previously adopted and the stockholders approved the Company’s 2017 Employee Stock Purchase Plan (the “2017 ESPP”). The 2017 ESPP is a broad-based plan that provides employees of the Company and its designated affiliates with the opportunity to become stockholders through periodic payroll deductions that are applied towards the purchase of Company common shares at a discount from the then-current market price. Subject to adjustment in the case of certain capitalization events, a total of 250,000 common shares of the Company were available for purchase at adoption of the 2017 ESPP. Pursuant to the 2017 ESPP, the annual share increase pursuant to the evergreen provision is determined based on the least of (i) 450,000 shares, (ii) 1.5% of the Company’s common stock outstanding at December 31 of the immediately preceding year, or (iii) such number of shares as determined by the Board. During January 2019, the Board determined not to increase the number of shares of common stock available under the 2017 ESPP pursuant to the evergreen provision of the 2017 ESPP. During the nine-month period ended September 30, 2019, the Company issued 38,279 shares of common stock under the 2017 ESPP. As of September 30, 2019, there were 440,195 shares of common stock remained available for issuance under the 2017 ESPP. A summary of stock option activity under the 2015 Plan, 2017 Plan and Inducement Plan for the nine-months ended September 30 , 2019 is presented below: Stock Options Outstanding Weighted- Weighted- average Number average remaining life of shares exercise price (in years) Balances — December 31, 2018 2,956,687 $ 17.04 7.6 Options granted 917,182 Options exercised (98,928) Options canceled (64,805) Options expired (164,645) Balances — September 30, 2019 3,545,491 $ 16.36 Exercisable — September 30, 2019 1,864,496 $ 16.18 The table above excludes 31,875 performance stock options granted during the six-month period ended June 30, 2018 for which the performance criteria had not been established as of September 30, 2019.

The estimated fair value of RSUs is recognized on a straight-line basis over the requisite service period. During the three-month period ended June 30, 2017, the Company granted 160,974 RSUs, all of which vested, pursuant to which no shares were issued, during June 2018. Additional paid-in capital was reduced by $0.1 million for tax payments related to shares withheld in connection with the vesting of the RSUs. During the nine-month period ended September 30, 2019, the Company issued 40,582 shares. Additional paid-in capital was reduced by $0.4 million for tax payments related to shares withheld in connection with the issuance of the RSUs. The stock-based compensation expense related to these RSUs was approximately $0 and $2.1 million for the three- and nine-month periods ended September 30, 2018, respectively. For the three- and nine-month periods ended September 30, 2019, there was no stock-based compensation expense recognized related to these RSUs. During the three-month period ended September 30, 2017, the Company granted 68,800 RSUs to certain employees which vest 50% on June 1, 2019 with the remaining 50% vesting on June 1, 2021.

Additional paid-in capital was reduced by $0.2 million for tax payments related to shares withheld in connection with the vesting of the RSUs. The stock-based compensation expense related to these RSUs was approximately $0.1 million and $0.3 million for the three-month and nine-month periods ended September 30, 2019, respectively. The stock-based compensation expense related to these RSUs was approximately $0.1 million and $0.3 million for the three- and nine-month periods ended September 30, 2018, respectively. |

Commitments And Contingencies [Abstract] | |
Commitments And Contingencies | 10. Commitments and Contingencies Operating Leases During January 2017, the Company entered into a Lease (the “Existing Lease”) with Hayward Point Eden I Limited Partnership, a Delaware limited liability company (the “Landlord”) for approximately 15,697 square feet for its corporate headquarters located at 3955 Point Eden Way, Hayward, California. The lease commenced during July 2017. During May 2019, the Company entered into a First Amendment to Lease (the “Lease Amendment”) with the Landlord. The Lease Amendment amends the Existing Lease with the Landlord and provides for the expansion of the Premises by approximately 34,601 square feet (the “Expansion Premises”) and an extension of the term of the Existing Lease. The Company will occupy the Expansion Premises in two phases. The “Phase 1” portion of the Expansion Premises contains approximately thirteen thousand two hundred and eighty ( 13,280 ) of rentable square feet and the “Phase 2” portion of the Expansion Premises contains approximately twenty-one thousand three hundred and twenty-one ( 21,321 ) of rentable square feet. Upon inclusion of the Expansion Premises, the Company will lease approximately fifty thousand two hundred and ninety-eight ( 50,298 ) rentable square feet from the Landlord (the “Entire Premises”). The Expansion Premises will also be used for the Company’s corporate headquarters and principal operating facility. The term of the lease for the Expansion Premises is expected to commence on the date the Landlord delivers Phase 1 of the Expansion Premises to the Company “Ready for Occupancy,” as defined in the Lease Amendment (the “Expansion Commencement Date”) and runs contemporaneously with the term of the lease for the existing space (the “Lease Term”). The Lease Amendment extends the term of the lease with respect to the Entire Premises to expire on the date that is ten ( 10 ) years after the Expansion Commencement Date. In addition, under the Lease Amendment, the Company has two options to extend the Option Term, as defined in the Lease Amendment, by seven ( 7 ) years upon written notice not more than twelve ( 12 ) months nor less than nine ( 9 ) months prior to the expiration of the lease, with monthly payments equal to the “Fair Rental Value” as defined in the Existing Lease. The Company will continue to pay base monthly rent for the existing premises in accordance with the terms of the Existing Lease. The Expansion Premises’ base monthly rent shall be abated for the first four ( 4 ) months of the Lease Term and thereafter will be $2.25 per rentable square foot for the Expansion Premises, with specified annual increases occurring thereafter until reaching approximately $3.819 per ren table square foot during the last six (6) months of the Lease Term. The total base rent beginning on the Expansion Commencement Date through the minimum term of the lease is not calculable at this time since the total base rent will depend on the date the Phase 2 portion of the Expansion Premises is “Ready for Occupancy.” In addition to base rent, the Company will continue to be required to reimburse the Landlord for certain expenses during the Lease Term. Under the Lease Amendment, the Company is required to increase its refundable security deposit by $264,264.88 to equal $364,937.68 . The Company adopted Topic 842 on January 1, 2019, using the transition method per ASU No. 2018-11 issued on July 2018 wherein entities were allowed to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC 840, Leases, and no retrospective adjustments were made to the comparative periods presented. The adoption of ASC 842 resulted in an increase to total assets and liabilities due to the recording of operating lease right-of-use assets (“ROU”) presented within other assets and operating lease liabilities of approximately $0.1 million as of January 1, 2019. Because the rate implicit in each lease is not readily determinable, the Company uses its incremental borrowing rate to determine the present value of the lease payments. The Company evaluated the Lease Amendment under Topic 842 and concluded that the Lease Amendment meets the definition of a lease modification as it extends the term of the Existing Lease and increases the Company’s leased premise. As the Company determined that the increase in payments under the Lease Amendment is not commensurate with the additional right-of-use assets provided in the modified lease, the modified lease is not accounted for as a separate contract. The remeasurement for the modification resulted in an increase in total lease lability of approximately $2.4 million, increase in right-of-use assets of $1.1 million, and other assets of $1.3 million. Information related to the Company's right-of-use assets and related lease liabilities were as follows (in thousands except for remaining lease term and discount rate): Cash paid for operating lease liabilities $ 263 Right-of-use assets recognized in exchange for new lease obligations 1,190 Current operating lease liabilities 177 Non-current operating lease liabilities 3,674 Total lease liabilities $ 3,851 Weighted-average remaining lease term 10.09 Weighted-average discount rate 10% Maturities of lease liabilities as of September 30, 2019 were as follows (in thousands): Year Ending December 31: 2019 (remaining 3 months) $ 136 2020 554 2021 574 2022 581 2023 577 Thereafter 3,792 Total lease payments 6,214 Less imputed interest (2,363) Total lease liabilities $ 3,851 During the three-month periods ended September 30 , 2019 and 2018, rent expense, including common area maintenance charges, was approximately $0.1 million and $57,000 , respectively. During the nine-month periods ended September 30 , 2019 and 2018, rent expense, including common area maintenance charges, was approximately $0.2 million and $0.2 million , respectively. Legal Proceedings The Company maintains indemnification agreements with its directors and officers that may require the Company to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law. From time to time, the Company may be involved in a variety of claims, lawsuits, investigations and proceedings relating to securities laws, product liability, patent infringement, contract disputes and other matters relating to various claims that arise in the normal course of the Company’s business. The Company currently believes that these ordinary course matters are not material to the financial statements of the business; however, the results of litigation and claims are inherently unpredictable. |

Summary Of Significant Accounting Policies [Abstract] | |
Basis Of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“Financial Statements”) have been prepared on a basis consistent with the Company’s December 31, 2018 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission and, as permitted by such rules and regulations, omit certain information and footnote disclosures necessary to present the financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements as of that date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These Financial Statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The results of operations for the three- and nine-month periods ended September 30, 2019 are not necessarily indicative of the results to be expected for the entire year or any future periods. |
Use Of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the Financial Statements and accompanying notes to the Financial Statements. Estimates include, but are not limited to, the valuation of cash equivalents and investments, the valuation and recognition of share-based compensation and the useful lives assigned to long-lived assets. The Company evaluates its estimates and assumptions based on historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. |
Recently Adopted Accounting Pronouncement | Recently Adopted Accounting Pronouncement During February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“Topic 842”), which amended prior accounting standards for leases. The Company adopted Topic 842 on January 1, 2019, using the transition method per ASU No. 2018-11 issued on July 2018 wherein entities were allowed to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Accordingly, all periods prior to January 1, 2019 were presented in accordance with the previous ASC 840, Leases, and no retrospective adjustments were made to the comparative periods presented. The adoption of ASC 842 resulted in an increase to total assets and liabilities due to the recording of operating lease right-of-use assets (“ROU”) presented within other assets and operating lease liabilities of approximately $0.1 million as of January 1, 2019. The adoption did not materially impact the Company’s Consolidated Statement of Stockholders’ Equity or Cash Flows. |
Significant Accounting Policies | Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies during the three- and nine-month periods ended September 30, 2019, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, except for the adoption of ASU No. 2016-02, Leases , as of January 1, 2019. |
Principles of Consolidation | Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Pulse Biosciences and its wholly-owned subsidiaries. Intercompany balances and transactions, if any, have been eliminated in consolidation. |
Net Loss Per Share | Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential dilutive common stock equivalents outstanding during the period. For purposes of this calculation, options to purchase common stock and common stock warrants are considered common stock equivalents. 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 net loss per share. Basic and diluted net loss per common share is the same for all periods presented because all warrants, stock options and restricted stock units outstanding are anti-dilutive. The following outstanding stock options, warrants and restricted stock units were excluded from the computation of diluted net loss per share for the periods presented because including them would have had an anti-dilutive effect: Nine-Month Periods Ended September 30, 2019 2018 Common stock warrants 213,485 213,485 Common stock options 3,545,491 2,858,387 Restricted stock units 111,305 222,606 Total 3,870,281 3,294,478 |
Reclassifications | Reclassifications Certain items in prior period financial statements have been reclassified to conform to the presentation in the current period financial statements. Such reclassifications did not impact the Company's previously reported net loss or financial position. |
