Toshiba Corp. said Monday it will spin off four key operations, including its infrastructure systems, to keep its shaky financial standing from affecting its healthy businesses.

Roughly 24,000 of about 30,000 Toshiba employees are likely to be transferred to the newly established companies, but engineers in the research and development division and some administrative staff will remain Toshiba employees.

The company is planning to spin off its infrastructure systems, energy systems, information technology-related businesses and electronic device operations.
