(Bloomberg) -- Oasis Management Co. called on potential bidders for Nippo Corp. to come forward as the activist shareholder lashed out at Nippo parent Eneos Holdings Inc.’s plan to take the company private with Goldman Sachs Group Inc. Any potential buyers withholding bids for fear of being perceived as hostile shouldn’t worry, as Eneos and Nippo have clarified that they’re open to alternative bids, Hong Kong-based hedge fund Oasis said in a website it set up Monday.
