Results were impacted especially by a number of natural catastrophe losses. Yet we feel the same about both the first and second quarter, as we are pleased with our progress on strengthening our underwriting businesses and adding to our leadership. We are at the same time excited with our progress in the first half of 2013, and reminded that we have room to improve."
