Ford is different in not taking the funds for now for a couple of reasons. One, they started their downsizing and depleating and combining all areas of their businesses. 5 or 6 years ago, (not at the last minute)
They shut down proving grounds, sold them (Gm/Crysler bought some of them for sure,)
Ford made decisions to shut down plants and consolodated plants, sold off makes, that would bring them back to basics and roots. Their CEOs, at least 2 of them, have not taken their pays, (one of them Being Bill Ford himself, the other, the Boeing guy in place now) by doing this helped give funds to keep things running and put money back into the business. (smart move)
I, personally,have not heard of GM or Crysler CEOs making the choices to not take their pay.
Ford was thinking further down the road than GM and Crysler, in my opinion and by them doing that, kept them from having to take the funds. However, that could change after a year.
