SAN FRANCISCO (Bloomberg) — Bermuda-based Marvell Technology Group Ltd., a chipmaker that fired executives for stock options backdating, restated results by $327.4 million to account for costs from those grants.The company reported that the net loss for fiscal year 2003 widened and that the profit reported for 2004 is now a loss, according to a regulatory filing. Marvell also reduced profit for 2005 and 2006.

Marvell, whose chips are in products such as Apple Inc.'s iPod music player, said in May that the restatement would cost as much as $350 million. The company is among more than 200 that have disclosed internal or federal probes into whether executives dated grants to when the stocks traded lower, inflating their value.

On April 24, Marvell said the US Securities and Exchange Commission broadened its review of the company's options practices to a formal investigation. Marvell first received a letter of informal inquiry last July.

In May, Marvell fired Matthew Gloss, former general counsel for the US, and said chief financial officer George Hervey resigned. Chief executive officer Sehat Sutardja, who participated in "a few instances" of backdating, stepped down as chairman.
