hive off 復習

Toshiba Corp will decide on Monday to raise some $5 billion from overseas investors, allowing the troubled conglomerate to remain a publicly traded company even if the sale of a key business is delayed, two people with direct knowledge of the process said.

Toshiba, reeling from the bankruptcy of its U.S. nuclear unit Westinghouse Co in the wake of an accounting scandal, needs to raise 750 billion yen ($6.7 billion) by the end of March to avoid being kicked off the Tokyo Stock Exchange.

The laptops-to-nuclear-reactors company has agreed to sell its prized NAND semiconductor unit for $18 billion, and is planning to sell its TV business and reportedly looking to hive off its personal-computer unit to raise cash.
