When chipmaker Analog Devices filed its 10-K report on Nov. 30, it announced that the SEC is conducting an inquiry into how the company has granted executive stock options. โ€œWe werenโ€™t under any obligation to make the statement,โ€ says Maria Tagliaferro, the companyโ€™s director of corporate communications. The companyโ€™s legal counsel believes that there may be other companies included in the same inquiry, but they are not yet known.
