Item 4. Controls and Procedures.
Effectiveness of Controls and Procedures
Our management, with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) in ensuring that the information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such information is accumulated and communicated to management (including the principal executive and financial officers) as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive and financial officers have concluded that such disclosure controls and procedures were effective as of March 31, 2022 (the end of the period covered by this Quarterly Report on Form 10-Q) at a reasonable assurance level.
Changes in Internal Control over Financial Reporting
In the first quarter of 2022, we implemented a new general ledger accounting system and complementary finance enterprise resource planning system. These new system implementations were achieved after a multi-year review of existing accounting and reporting processes and the design and configuration of system-enabled enhancements to such processes. With the implementation, we have realized certain process efficiencies and we expect this new system to enhance our financial reporting and analysis capabilities in the future. The change in our general ledger and finance enterprise resource planning systems was subject to thorough testing and review by internal and external parties both before and after the implementation. While these systems implementations are intended to enhance our framework for internal control over financial reporting, management, together with our CEO and CFO, has determined that the changes in our internal controls over financial reporting during the quarter ended March 31, 2022 have not been material and are not reasonably likely to materially affect our internal controls over financial reporting.
