In an e-mail response to FRONTLINE's producers, KBR made the following point about the March 31, 2004 incident in Fallujah:

• "ESS is indeed a KBR subcontractor; however, it also contracts directly with the U.S. government and with other companies working in Iraq. Although we can't speak for ESS or Blackwater, we can tell you that it is KBR's position that any efforts being undertaken by either company when the March 31, 2004 attack occurred were not in support of KBR or its work in Iraq. Again, since this was not a KBR-directed mission, it would be inappropriate for us to speculate about what happened."

KBR also made the following point about the camp to which the convoy was apparently headed:

• "Although KBR does handle a large portion of the logistics and life support services for the Army in Iraq, KBR was not responsible for operating the DFAC [dining facilities] at Camp Ridgeway during this period."
