An announcement had been expected to come after China's regulators gave the deal the final government blessing it needed to reach the finish line.
Page said Motorola chief Sanjay Jha is stepping down, and that Google's Dennis Woodside will be replacing him, another move that had been widely anticipated.
Overall, the Google-Motorola deal rode an easy, fast track to regulatory approvals worldwide, with no conditions being imposed on the acquisition. However, many observers have wondered how effectively the Internet giant can integrate and run a hardware vendor focused on lower-margin business opportunities.

Motorola Mobility, for its part, recently reported an $86 million net loss for the first quarter, slightly above its loss for the same quarter in 2011. It also saw its total handset shipments slip year-over-year, from 9.3 million to 8.9 million, though it did see smartphone shipments jump from 4.1 million in Q1 2011 to 5.1 million in Q1 2012.
Meanwhile, it continued to experience declining revenue in its set-top box business, a unit that at times has been rumored to be headed for the auction block under Google's watch.
