Sharp Corp's list of liabilities that prompted Taiwan's Foxconn to suspend signing a takeover deal was an unverified study of worst-case scenario risks, rather than liabilities requiring disclosure, a source briefed on the matter said. The list, sent to Foxconn on Wednesday, included previously undisclosed potential liabilities worth around 300 billion yen ($2.6 billion), prompting Foxconn founder and billionaire Terry Gou to hold off signing the estimated $5.8 billion deal, separate sources have said.
