(Telecompaper) Merger discussions for the PC units of Toshiba, Fujitsu and Vaio are on the verge of collapse, the Wall Street Journal reported, citing sources familiar with the matter. Japan Industrial Partners, a fund that bought a controlling stake in Vaio from Sony in 2014, has already left the table. Fujitsu is still in discussions with Toshiba, but neither wants to take a majority of the proposed joint company, putting the talks at risk of falling apart.
