I need to clarify one aspect before answering your question.

We need to remember that the fraudulent overbilling occurred by individual subcontractors. The security clearances of those individual subcontractors have been revoked, and they can no longer work on those contracts.

They were hired by multiple prime contractors. Those prime contractors were sometimes not aware of the overbilling, but they accepted to reimburse us, because it was their responsibility under their contract with us.
