Item 15. Controls and Procedures
Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the risk related to controls and procedures.
In connection with the preparation of the 2022 Form 20 - F, as of December 31, 2022, an evaluation was performed under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a - 15 (e) and 15d - 15 (e) under the Exchange Act). Based upon that evaluation, at the time the 2002 Form 20 - F was filed, our CEO and CFO concluded that our disclosure controls and procedures were effective as of December 31, 2022. Subsequent to that evaluation, our management, including our CEO and CFO, conducted a re - evaluation, concluding that our disclosure controls and procedures were ineffective as of December 31, 2022 due to the identification of the material weakness discussed below.
Management's Annual Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Exchange Act Rules 13a - 15 (f) and 15d - 15 (f) define this as a process designed by, or under the supervision of, the Company's principal executive and principal financial officers and effected by the board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with (a) UK - adopted international accounting standards; and (b) IFRS, including interpretations issued by the IFRS Interpretations Committee.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.
In connection with the preparation of the 2022 Form 20 - F, our CEO and CFO conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2022, based on the framework established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based upon that assessment, at the time the 2022 Form 20 - F was filed, our CEO and CFO determined that our internal control over financial reporting was effective as of December 31, 2022. Subsequent to that assessment, our management, including our CEO and CFO, conducted a re - assessment, concluding that our internal controls over financial reporting were ineffective as of December 31, 2022 due to the identification of the material weakness discussed below.
Identified Material Weakness
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
