TOKYO -- The Harvard University endowment fund, a major Toshiba shareholder, sold its shares in the company as of March, Nikkei has learned. They were acquired by an "activist investor" in Singapore that voted against Toshiba President Nobuaki Kurumatani and others at the 2020 shareholders meeting. Tensions between shareholders and the current management team may now rise even higher. The Harvard fund sold its Toshiba shares to 3D Investment Partners, a Singapore-based asset management company.
