According to team principal Monisha Kaltenborn, Sauber has now improved its financial condition.
Following a 2014 campaign void of a single championship point, and a 2015 season which started with a financial agreement to settle Geido van der Garde's claim to a race seat with the team, Sauber found itself in a precarious financial position.
But at the half-way mark of the current season the Swiss outfit has improved its economic health, collecting 22 points and securing its future in Formula 1, at least in the mid-term, which will include both Felipe Nasr and Marcus Ericsson.
"Our financial position is better overall," Monisha Kalteborn told ESPN. "Already towards the end of last year we were looking step-by-step better, even if it was very small steps it was going in the right direction."
"If those steps had not been there, I guess these drivers would not have decided that they already wanted to talk to us and be in this team. So the basis is there and we are moving in the right direction."
Kaltenborn believes that extending the contract of its two resident drivers forestalls any unwanted speculation, which in turn brings clarity to Sauber.
"It just brings in a certain consistency, and stability of course, and it just clams things down. There are so many rumours around and our drivers then get questions and they don't know what to say and what is right and what is wrong. It clarifies the situation, it's transparent and now everyone knows and all those topics of speculation are over as far as we are concerned."
