Analog Devices Inc.

A lawsuit has been filed and is seeking class action status against the Norwood chip maker and several of its executives, claiming the company's stock has suffered since an investigation into its stock option awards became public. The lawsuit was filed in US District Court in Boston on behalf of employees claiming Analog Devices enriched its executives by improperly backdating its stock options. The lawsuit also claims current and former employees enrolled in Analog's retirement plan suffered as stock fell after the company disclosed an investigation. In November 2005, Analog Devices agreed to pay a $3 million settlement to the Securities and Exchange Commission to resolve concerns about options grants.
