Let's start with the obvious: GM (NYSE:GM) didn't need this.
It's already got problems with profitability, coupled with a terrible sales slump it shares with Ford (NYSE:F) -- but not with peers like DaimlerChrysler (NYSE:DCX), Honda (NYSE:HMC), or Toyota (NYSE:TM). Its debt is rated only slightly more attractive than discarded orange rinds, and now comes word of a restatement to the tune of oh, half a billion bucks, more or less. Less, actually -- $300 million to $400 million for 2001, and who knows what after that.
Officially, it is merely one "error" among several under investigation by the Securities and Exchange Commission -- this one regarding how and when supplier credits were recorded.
Now, before I start in with the criticism, I want to illustrate for you how serious GM is about trust and corporate stewardship.
As far as I can tell, the investors' PR file at the GM site includes no press release on this topic. (It was released as an 8-K to the SEC). Yet the automaker does have time today put together a few paragraphs to let us all know about something it calls the Escalade on Rodeo. With priorities like these, it's no wonder this company is sinking like a rock.
In the end, this $400 million -- and when, where, or even if it was ever earned -- may be immaterial. But for anyone out there still brave enough to invest in GM, this ought to highlight the complexity that hides beneath the surface of the car company-cum-mortgage banker.
Like Ford (whose silly earning tricks I highlighted a while back), or any other bank, GM's profits are based on all sorts of arcane opinions, decisions about reserves, and other far-from-obvious figures. It's not just "sell a car, subtract what it cost to build it, and book the difference as profit or loss." Toss in pension and health-care accounting, and you're looking at a company that may have all sorts of other super-scary skeletons waiting to jump out of the closet and give investors a bony, bladder-loosening hug.
Invest accordingly.
