Toshiba Corp. is considering selling some of its shares in U.S. subsidiary Westinghouse Electric Co. in an effort to prepare for a fund shortage as its accounting scandal shows no signs of abating, company sources said Thursday.

The Japanese electronics maker said in a press release it has nothing to disclose at the moment, adding its policy of retaining a majority stake in the nuclear equipment-manufacturing unit remains unchanged.

Toshiba bought Westinghouse in 2006 for roughly ¥640 billion ($5.27 billion) to strengthen its nuclear power business, and purchased an additional 20 percent stake for ¥125 billion in 2013, raising its stake in the company to 87 percent.
