Ford Motor Company on Wednesday filed restated third quarter and nine-month accounts with US regulatory authorities after correcting accounting errors related to interest rate hedging at its finance unit.

For the third quarter and first nine months of 2006, the company reported a net loss of $5.2bn and $7bn, respectively; improvements of about $550m and $250m, respectively, from the preliminary results released on 23 October.

The restatement was due primarily to the way interest rate hedging had been accounted for at finance arm Ford Motor Credit Company.

The restatement's cumulative impact on net income was an increase of about $850m, according to a statement from the automaker.
