Broadcom declined to discuss local ramifications and referred questions to Tuesday's regulatory filing, which did not provide specific geographic details on the pending cuts and office closures. "Unfortunately, we do not break the numbers out," a company spokesperson told the Business Journal. Broadcom currently employs about 2,500 people at its Irvine campus next to the University of California-Irvine. The office is home to corporate personnel, including administrative, marketing, sales, legal and human resources, as well as engineers. It employed about 12,550 people companywide at the end of 2013, according to its annual report. The restructuring follows Broadcom's June announcement that it would exit the baseband chip business, a segment dominated by San Diego rival Qualcomm Corp. Baseband chips are essentially the technical brains of mobile phones.
