Presumably, the civil servants who awarded the contracts and who determined that outsourcing was required in those cases, because the audits made it very clear there was no political interference, would have determined if they saw deficiencies in the work that McKinsey was doing under the contract and would have sent notices of default.
You're saying that nobody ever got a notice of default and that McKinsey is not aware of any breach of any of these contracts that it ever had.
