A Delaware bankruptcy judge approved a settlement between electric car maker Fisker Automotive Inc. and its former battery supplier, the Associated Press reported yesterday. The settlement reduces Fisker's claims against the company formerly known as A123 Systems Inc., now called B456 Systems Inc., by almost 90 percent. Fisker will be granted a $15 million unsecured claim on an initial claim of $48.7 million against A123 for breach of warranty. Fisker’s $91.2 million claim for rejection of its supply agreement with A123 will be disallowed.
