EMC Insurance Group Inc. today announced that second-quarter 2018 results were negatively affected by a higher than anticipated level of non-catastrophe losses in the property and casualty insurance segment. As a result, the Des Moines-based insurer expects to report a net loss in the range of 22 to 26 cents per share for the second quarter. The largest factor contributing to the expected loss occurred in the workers’ compensation line of business, and is attributed to unanticipated increases in both the frequency and severity of losses, compounded by mandatory rate decreases implemented during the past few years. In addition, the commercial auto and personal lines of business continued to underperform, the company said. Catastrophe and storm losses are expected to be about $15.7 million in the property and casualty insurance segment and a relatively low amount of about $1 million in the reinsurance segment. The total of $16.7 million is below projections, but is about $1.6 million higher than the second quarter of 2017.
