The interim consolidated financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements, as allowed by the relevant SEC rules and regulations; however, the Company believes that its disclosures are adequate to ensure that the information presented is not misleading. Certain reclassifications have been made to the prior year financial statements to conform to the presentation used in the current year. In the current year the Company reclassified certain current accrued expenses to Other liabilities on the Consolidated Balance Sheets. These reclassifications did not have an impact on total assets or total liabilities of the Consolidated Balance Sheets or cash flows as previously reported.
Reverse Stock Split	Reverse Stock Split On April 26, 2022, the Company effected a reverse stock split of its common stock, par value $0.00001 per share, at a ratio of 1-for-25 (the “2022 Reverse Stock Split”). As a result of the 2022 Reverse Stock Split, (i) every 25 shares of the issued and outstanding common stock were automatically converted into one newly issued and outstanding share of common stock, without any change in the par value per share; (ii) the number of shares of common stock into which each outstanding warrant or option to purchase common stock is exercisable was proportionally decreased, and (iii) the number of authorized shares of common stock outstanding was proportionally decreased. Shares of common stock underlying outstanding stock options and other equity instruments convertible into common stock were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities. The 2022 Reverse Stock Split became effective at 5:00 pm New York time on April 26, 2022, with the common stock trading on a post-split basis under the Company's existing trading symbol, “NVIV,” at the market open on April 27, 2022. Fractional shares resulting from the 2022 Reverse Stock Split were rounded up to the nearest whole share, and all shares of common stock (including fractions thereof) issuable upon the 2022 Reverse Stock Split to a given stockholder were aggregated for the purpose of determining whether the 2022 Reverse Stock Split would result in the issuance of a fractional share. Pursuant to Section 78.209 of the Nevada Revised Statutes, the Company’s Board of Directors was able take action to effect the 2022 Reverse Stock Split by filing a Certificate of Change with the Secretary of State of the State of Nevada without the consent of the Company’s stockholders. All of the Company’s historical share and per share information related to issued and outstanding common stock and outstanding options and warrants exercisable for common stock in these consolidated financial statements have been adjusted, on a retroactive basis, to reflect the 2022 Reverse Stock Split.
