Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of our Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as of December 31, 2023. The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports the Company files under 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 the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosures. In designing and evaluating our disclosure controls and procedures, the Company’s management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints that require the Company’s management to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on this evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2023, the Company's disclosure controls and procedures were not effective because of a material weakness in the Company's internal control over financial reporting related to fees and allowances paid to distributors for distinct services.

Management's Report on Internal Control over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company's management evaluated the effectiveness of its internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on that evaluation, the Company’s management has concluded that, as of December 31, 2023, our internal controls over financial reporting were not effective because of the existence of a material weakness in internal control over financial reporting related to fees and allowances paid to distributors for distinct services.

Material Weaknesses in Internal Control Over Financial Reporting

A material weakness is defined as a deficiency or combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

With respect to the fees and allowances paid to distributors for distinct services, the execution of the controls over the application of accounting literature did not operate effectively with respect to:

Remediation Process

The Company is evaluating the material weaknesses and developing a plan of remediation to strengthen the effectiveness of the design and operation of its internal control environment. The remediation plan will include the following actions:

The actions that the Company is taking are subject to ongoing senior management review as well as Audit Committee oversight. The Company is committed to maintaining a strong internal control environment and believes that these remediation efforts will represent significant improvements in its controls. The Company has started to implement these steps; however, some of these steps will take time to be fully integrated and confirmed to be effective and sustainable. Additional controls may also be required over time. Until the remediation steps set forth above are fully implemented and tested, the material weakness described above will continue to exist.

Changes in Internal Control over Financial Reporting

There were no changes to the Company’s internal control over financial reporting during the fourth quarter of 2023 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Inherent Limitation on the Effectiveness of Internal Controls

The effectiveness of any system of internal control over financial reporting is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting can only provide reasonable, not absolute, assurances. 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. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure that such improvements will be sufficient to provide us with effective internal control over financial reporting.
