"Our fourth quarter caps a strong year in which we completed and integrated several strategic acquisitions, delivered higher investment returns, achieved record revenue, strengthened our balance sheet through preferred stock issuances, returned more than $262 million of capital to shareholders in the form of common share repurchases and dividends, and produced book value per share of $15.15 at year-end, an increase of over 17% from a year ago," said Barry Zyskind, chairman and chief executive officer, AmTrust. "We are very pleased with the underlying operational performance of our business in the fourth quarter and in 2016, a year in which we continued to maintain high levels of policy retention and maintain underwriting discipline. While our expense ratio was elevated in the fourth quarter, due largely to business mix as well as higher costs related to increased year-end resources, expenses were otherwise in line with our net earned premium growth."
