Congressional Budget Office Cost Estimate: H.R. 5715, No Ex-Im Assistance for Terrorism Act [open pdf - 14KB]
From the Document: "H.R. 5715 would prohibit the Export-Import Bank (Ex-Im) from providing any export financing that would benefit the Government of Iran or Iranian entities. Under current law, Ex-Im is barred from doing business in Iran and it currently has no outstanding financing related to that country. On that basis, CBO [Congressional Budget Office] estimates that implementing the bill would not affect lending by Ex-Im and would have no effect on the federal budget."
