Amendment Description | Xenon Pharmaceuticals Inc. (the “Company,” “we” or “us”) is filing this Quarterly Report on Form 10-Q for the three months ended March 31, 2020 (this “Form 10-Q”) in reliance upon the relief set forth in the Order (the “Order”) issued by the Securities and Exchange Commission (the “Commission”) on March 25, 2020 (Release No. 34-88465) under Section 36 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Order provides conditional relief to public companies that are unable to timely comply with certain filing obligations as a result of the novel coronavirus (“COVID-19”) outbreak. This Form 10-Q could not be filed within the time period specified under the Exchange Act, absent the relief available under the Order, due to the outbreak and spread of COVID-19. Specifically, employees in the Company’s financial reporting and legal departments have been working remotely and therefore been unable to maintain the same ordinary course interactions with the Company’s professional advisors. As a result, the preparation and completion of the Company’s financial statements for the three months ended March 31, 2020 to be included in this Form 10-Q was delayed.Pursuant to the requirements of the Order, we filed a Form 8-K with the Commission on May 6, 2020 indicating our intention to rely upon the Order with respect to the filing of this Form 10-Q, which would have otherwise been required to have been filed by May 11, 2020. This Form 10-Q is being filed within the 45-day extension period provided by the Order. | |
