Yes.
The purpose of having ministerial oversight is because taxpayers' dollars are at stake. At the beginning of the fourth year, you can imagine a situation, however unlikely, where government guarantees have been invoked for borrowing purposes, including for purchases of real property, with taxpayers' money backing up those borrowings. If the corporation were to go private, the taxpayers would be on the hook for those moneys.
This is simply an insurance policy so that the privatization model doesn't put taxpayers' funds at risk.
