substantial beneficial interest
(1) In general In the administration of section 506 of the Federal Crop Insurance Act, the Federal Crop Insurance Corporation may require each policyholder and each reinsured company to furnish to the insurer or to the Corporation the employer identification number of such policyholder, subject to the requirements of this paragraph. No officer or employee of the Federal Crop Insurance Corporation, or authorized person shall have access to any such number for any purpose other than the establishment of a system of records necessary to the effective administration of such Act. The Manager of the Corporation may require each policyholder to provide to the Manager or authorized person, at such times and in such manner as prescribed by the Manager, the employer identification number of each entity that holds or acquires a substantial beneficial interest in the policyholder. For purposes of this subclause, the term “substantial beneficial interest” means not less than 5 percent of all beneficial interest in the policyholder. The Secretary of Agriculture shall restrict, to the satisfaction of the Secretary of the Treasury, access to employer identification numbers obtained pursuant to this paragraph only to officers and employees of the United States or authorized persons whose duties or responsibilities require access for the administration of the Federal Crop Insurance Act.
