The combined ratio was 101% for the second quarter of 2014 compared to 103% for the second quarter of 2013. The combined ratio was 98% for both the six months ended June 30, 2014 and 2013. Excluding the impact of one-time events and charges in 2013 described below, our combined ratio increased in both periods of 2014 compared to 2013.
The results for the quarter and six months ended June 30, 2013 were impacted by $61.8 million of transaction costs and acquisition-related expenses related to the acquisition of Alterra and $25.4 million of catastrophe losses. Together these items added 11 points and six points to the consolidated combined ratio for the quarter and six months ended June 30, 2013, respectively. The quarter and six months ended June 30, 2014 included less favorable development on prior years' loss reserves compared to the same periods in 2013, primarily in our U.S. Insurance segment. Prior year losses for the quarter and six months ended June 30, 2014 included $27.2 million of adverse development on asbestos and environmental exposures within our Other Insurance (Discontinued Lines) segment.
Alan I. Kirshner, Chairman and Chief Executive Officer, commented, "We are pleased with our growth in book value for 2014, which was driven by strong performance in our equity and fixed income investment portfolios. Our underwriting results in 2014 included unfavorable development on our asbestos and environmental exposures, which have continued to adversely impact the property and casualty insurance industry. We continue to expand our non-insurance operations and are excited about our most recent acquisition of Cottrell in July 2014."
