Newport Beach-based Irvine Company told the Business Journal at the time that Broadcom agreed to move out of the two buildings ahead of schedule so the Toshiba unit could move in by October. Broadcom is steadily vacating space at 11 buildings it leases at the 36-building, 2.2-million-square-foot office campus Irvine Co. built for the chipmaker in 2005. Broadcom is moving its operation to Great Park Neighborhoods near Irvine's train station and agreed this month to sell back the campus that's under construction for $443 million to Aliso Viejo-based master developer FivePoint Communities Inc. Broadcom Ltd. was established last year after Singapore-based Avago Technologies Inc. acquired Broadcom Corp. in Irvine for $37 billion and settled its U.S. headquarters in San Jose.
