The adjudicative officer shall issue an initial decision on the application as promptly as possible after the filing of the last document or conclusion of the hearing. The decision must include written findings and conclusions on the applicant's eligibility and status as a prevailing party, including a finding on the net worth of the applicant. Where the adjudicative officer has determined under §13.11(b) that the applicant's net worth information is exempted from disclosure under the Freedom of Information Act, the finding on net worth shall be kept confidential. The decision shall also include, if at issue, findings on whether the agency's position was substantially justified, whether the applicant unduly protracted the proceedings, an explanation of any difference between the amount requested and the amount awarded, and whether any special circumstances make the award unjust.
