Nov 27 (Reuters) - Activist investor Elliott Investment Management on Monday said it was ready to nominate directors at Crown Castle International and push for the ouster of the wireless tower owner's executives and board members, whom it blames for years of underperformance. The hedge fund in a letter released on Monday said the company needs "comprehensive leadership change." It said it was ready to appeal to other shareholders to make changes to the 12-member board, signaling a possible proxy fight next year. Elliott sharply criticized management and the board saying a "lack of oversight ... contributed to its irresponsible stewardship and flawed financial policy." The hedge fund said the company "disregarded our data-driven analysis" and added that "our recommended changes were neither made nor taken seriously."
