Eight executives from 15 Lower Hudson Valley hospitals received more than $1 million in salary, bonuses, benefits and other pay in 2010 at a time when the state struggled to control health-care costs. A Journal News analysis of tax records shows they included CEOs and top physicians who earned five times more than a cap ordered last month by Gov. Andrew Cuomo for nonprofit organizations, a move to restrict the amount of state money they can use on executive compensation to $199,000 a year.
