## Controversies

In 2008, the company and its then chief operating officer–and the only member of its stock option "committee" during the period in question – Weili Dai paid fines, to the Securities and Exchange Commission over charges of false financial information to investors by improperly backdating stock option grants to employees, totaling $10 million and $500,000 respectively. Dai was forced to step down as executive vice president, chief operating officer, and a director but allowed to continue with the company in a non-management position.
In 2016, Dai and her husband, Sehat Sutardja, were ousted from Marvell Technology Group, the company they had co-founded, after months-long investigation on a potential accounting fraud. The investigation found no fraud, however, it found that there were significant pressures from management to meet revenue targets and that internal controls were not fully followed and some revenues were booked prematurely early.
