''The teams have demonstrated that they are not capable of being able to agree a cost control, so the answer is to take it outside of the teams' control. It's up to the FIA to decide a formula, bring that in and implement it.''
Aside from cost reduction, another means of sustaining the teams is for more of the money earned by the commercial rights holder to be passed on to the teams.
''We may have missed an opportunity to just sit down with the commercial rights holder and re-negotiate something which could have been more in favor of the teams, but we failed,'' Boullier said.
Tost said getting more money flowing from TV rights and sponsorships to funnel down to the teams was not the answer.
''It's easy to say we should get more money, but give the engineers one million and they ask for two. Give them four million and they ask for eight.''
Boullier agreed, saying increased revenue must work in concert with tighter regulations to control spending.
''The more money you get, the more money we will spend if you don't have any safeguards around you,'' Boullier said. ''The more open the regulations are, the more we will spend money and waste money.''
