RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate.)


☒     (a)   The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;
  (b)   The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-CEN or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
  (c)   The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.



State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Company is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 20-F for its fiscal year ended December 31, 2023 (the “2023 Annual Report”).

The Company is unable to file the 2023 Annual Report within the prescribed time period without unreasonable effort or expense because the Company requires additional time to complete its 2023 Annual Report preparation and review process and its assessment of its internal control over financial reporting. In particular, as a result of its work to date, the Company expects to disclose material weaknesses in its internal control over financial reporting at December 31, 2023. Consequently, management expects to conclude that its internal control over financial reporting and, as a result, its disclosure controls and procedures were not effective at December 31, 2023.

As a result of the foregoing, the Company has not yet completed its year-end reporting procedures required for its independent registered accounting firm to complete its audit procedures. The Company expects to file its 2023 Annual Report within the 15-calendar day extension provided by Rule 12(b)-25(b).
