I think the focus shouldn't be on the companies per se but rather on what they're doing. You need to have pretty stringent oversight and make sure that the contracts are being managed effectively, and that's more important than what the country may have done eight or nine years ago. So it's more important to make sure that what's being done is executed to the letter of the contract, and to look and make sure that you're getting what you're paying for and that the people who are doing things for you are staying within the parameters you outlined for them at the outset.
I think the focus should be on that kind of enforcement rather than worrying particularly about whether the contract went to a certain company that may or may not have had a bad reputation in the past.
