A spokesman for KBR stressed that there is a new management team in place since the company built the controversial detention centre:
The incidents of the past occurred in 1994 through 2004 when KBR was owned by Halliburton.
Since 2006, KBR has brought in a completely new management team which is committed to best-in-class compliance.
Compliance and integrity are at the very core of everything we do at KBR.
We believe our best-in-class compliance programme, coupled with the unique skills and qualifications of our workforce, will be an extremely strong asset throughout the bid process.
