Summary Box: Ericsson sells Sony Ericsson stake

THE BREAKUP: LM Ericsson and Sony Corp. will go their separate ways as Ericsson sells its 50 percent stake in mobile phone maker Sony Ericsson to Sony for $1.46 billion. The agreement is expected to close in January.

WHAT HAPPENS NOW: Sony Ericsson will become a subsidiary of Sony and integrated into Sony’s platform of network-connected consumer electronics products. Officials say the transaction gives Sony an opportunity to integrate smartphones with consumer electronics devices, such as televisions and computers.

GOOD MOVE: Analysts have argued Sony Ericsson could become more competitive in the tough smartphone market under sole Sony ownership.
