Such initial estimate may be based on insured loss amounts as compiled by insurance industry statistical organizations, data previously collected by the Secretary, and any other information the Secretary in his or her discretion considers appropriate. The Secretary shall also notify Congress if estimated or actual aggregate insured losses exceed $100,000,000,000 during any calendar year.
