Toshiba Corp’s second postponement of its annual results due to newfound accounting errors should be met with a tough response from regulators, Japanese lawmakers urged on Wednesday. The Tokyo Stock Exchange would consider putting Toshiba’s shares on a watchlist for possible delisting if there were further delays, Masahiko Shibayama, head of the Liberal Democratic Party’s treasury and finance division, quoted a bourse official as saying in a meeting of lawmakers and regulators. Sources familiar with the matter have previously said that regulators are studying the case to weigh possible fines.
