Stan Galanski, Navigators' Chief Executive Officer, commented, "We are pleased with the strong underwriting results for the second quarter. Our record quarterly net income reflects our culture of underwriting discipline, favorable loss development, growth in investment income and the ongoing execution of our strategy. We are encouraged that incurred loss activity remains well within our expectations and that our loss reserves have never been stronger. Despite increasingly challenging market conditions, we continue to deliver shareholder value by capitalizing on growth opportunities in a number of product lines and geographic niches. At the same time, our underwriters continue to refrain from writing business that fails to meet our underwriting standards."
