Changes in citizenship data.

(a) It is incumbent upon the party filing an affidavit under this part to apprise MARAD promptly in writing relative to changes in data last furnished with respect to officers, directors, and stockholders holding 5 percent or more of the issued and outstanding stock of each class or series, together with statements concerning the citizenship status thereof. (b) If the information contained in a party's most recent affidavit of citizenship filing has not changed materially, as an alternative to submitting an annual affidavit of citizenship under this part, a party may file a certification with MARAD. The certification should be substantially in the following format: “I, , [Title] of [Name of Corporation] (“Corporation”), being duly authorized by the Corporation, certify to you that there have been no changes to the ownership information contained in the Affidavit of Citizenship filed with the Maritime Administration on [DATE].”
