Caesars World Inc. announced a shareholder rights plan, which it said is designed to deter “coercive or unfair” takeover tactics against the Los Angeles-based casino operator. Last month, New York financier Donald J. Trump asked federal regulators for clearance to buy 15% or more of Caesars’ stock. Under the plan adopted by the company’s directors, preferred stock purchase rights will be distributed as a dividend as of Jan. 23. They will entitle shareholders to buy the new preferred, to be exercisable under certain conditions.
