Congressional Budget Office Cost Estimate: H.R. 5729, Stop U.S. Support for State Sponsors of Terrorism Act [open pdf - 14KB]
From the Document: "H.R. 5729 would amend current law to prohibit the Department of the Treasury from issuing a license for the export of commercial aircraft to Iran. The bill also would require the Treasury and the Export-Import Bank to provide an annual report on the financing and sale of aircraft and aircraft parts to Iran. CBO [Congressional Budget Office] estimates that implementing H.R. 5729 would increase administrative costs at the Treasury and the Export-Import Bank by less than $500,000 annually; such spending would be subject to the availability of appropriated funds. In addition, on the basis of information from the Export-Import Bank, CBO estimates that implementing the bill would have no effect on the bank's lending activities. Because the bill would expand prohibited types of trade with Iran that are subject to civil and criminal penalties, it could increase revenues and associated direct spending; therefore, pay-as-you-go procedures apply. However, CBO estimates that the net budgetary effect of any additional penalties would be negligible for each year."
