Despite Ford’s surging stock price, new models and rising customer confidence there’s always been that one bone of contention which had divided peoples’ opinion: debt. $35 billion of it. Though they’ve tried to restructure it, selling new shares and raising cash throughout 2009, it’s still a problem. But apparently it’s becoming less of a problem. ABC news report that Fitch Ratings upgraded their assessment of the risk of Ford defaulting on its debt obligations, basing their optimistic view on a better economic environment, the company’s stronger margins, increased market share and cash position. Oh yes, and a small matter of $5.9b in federal DOE retooling loans [full Fitch release here]. Ford’s Credit unit also received a hearty slap on the back from Fitch because of its improving access to capital, as its rating was raised from “CCC” to “B-“. But let’s not get carried away. While this is a positive step in Alan Mulally’s vision of a sustainable Ford, the rating still qualifies Ford debt as non-investment grade.
