The Hanover Insurance Group, Inc. provided earnings guidance for the fourth quarter of 2018. The company estimated catastrophe activity would impact fourth quarter operating results by approximately $50 million before taxes, or 4.6% of net premiums earned, compared to its fourth quarter catastrophe assumption of 3.6%. Catastrophe losses in the quarter stemmed primarily from the Camp and Woolsey wildfires in California, as well as Hurricane Michael. Additionally, the company's fourth quarter results will be impacted by higher than expected current accident year losses, driven by elevated property activity, partly due to large losses and non-catastrophe weather, as well as increases in auto bodily injury loss severity. Taking these factors into account, the company expects its fourth quarter combined ratio to be in the range of 97.4% to 97.8%. This would bring its full year combined ratio to approximately 96.2%, and 91.0%, excluding catastrophes.
