Ford Motor Co. says it lost $8.7 billion in the second quarter largely because of a reduction in the value of assets.

The company also announced that it will bring six European small car models to North America by the end of 2012 as it deals with a market shift from trucks to cars brought on by high gasoline prices. The company also will retool two U.S. truck and sport utility vehicle plants to build small, fuel-efficient vehicles.

The second-quarter loss was $3.88 per share, compared with a net profit of $750 million, or 31 cents per share, in the same quarter a year ago.

The loss includes $8 million worth of write-offs because of a decline in value of North American assets and Ford Motor Credit Co.’s lease portfolio.
