Tech giant Samsung Electronics, under pressure from shareholders to improve investor returns, said on Tuesday it will consider creating a holding company in what would be the biggest shake-up in its 47-year history. Reuters reports: The move and a plan to raise dividends come after U.S. hedge fund Elliott Management in October called for the South Korean firm to split itself into a holding vehicle and an operating company. However, the world's top maker of smartphones, memory chips and televisions, said it was "absolutely neutral" about whether to proceed and provided little detail on the potential restructuring, underwhelming investors. "The review does not indicate the management or the board's intention one way or another," the company said in a statement, adding it had hired external advisers for a review expected to take at least six months. Shares in Samsung, worth $224 billion combined, finished unchanged on the day at 1.677 million won ($1,434) each. The 2016 dividend boost fell short of some expectations, while uncertainty over the restructuring kept investors at bay, analysts said.
