The Airline Group acquired a 46% share, a majority on the Board and operational control of NATS despite having paid only one sixteenth of the purchase price, the rest being financed by loans repayable by NATS itself. Departments undertaking PPPs should ensure that their chosen strategic partners accept risk commensurate with their control of the business and the accompanying responsibilities.
In my mind they are responsible for the risks they took on and therefore they should be providing the funding to ensure the fund - not the staff.
