mr. chairman, this is a nice place for a freshman to sit. i'd like to commend you for your leadership on these issues and thank you secretary burns for your testimony. on september 30th, deputy secretary steinberg announced that state oil and eni and world dutch pledged to end investment in iran energy sector and as a result the personal rule provided for there was no investigation into their activity. the special rule provides that and as the notice stated that they are not longer engaging in or have taken steps towards stopping activity. my first question is to what extent do those four companies continue to operate in iran's energy sector? >> just to add, sir, there's a 5th company since then too which the special rule applied impacts, a japanese company. broadly, it's a demonstration that that instrument, an important one, is working to produce the outcome that we want. with regard to the companies you mentioned, i can try to get you a more detailed answer, but we've had detailed conversations with nose companies. they are winding down quite rapidly, and they have given us clear assurances that not only are they winding down current operations, but they are not participating in any sanction
