Excess and Surplus Lines Segment

The Excess and Surplus Lines segment reported gross written premiums of $140.0 million in the first quarter, up $12.4 million or 9.7% from the first quarter of 2013. Growth was driven primarily in certain specialty casualty lines of business.  Net written premiums were down 2.5% to $98.2 million, and earned premiums were up 11.7% to $117.4 million.  The decline in premiums written reflects changes to the accounting for certain reinsurance contracts in this segment.

Commercial Specialty

Commercial Specialty reported gross written premiums of $105.9 million in the first quarter, down slightly from $106.1 million in the first quarter of 2013.  Declines due to portfolio repositioning in our public entity unit were offset by new product initiatives and strong renewal retention at Argo Insurance and growth at Argo Surety. Net written premiums were down 5.1% to $68.0 million, and earned premiums were down 4.7% to $71.7 million. The segment reported an underwriting loss of $1.1 million for the quarter compared to underwriting income of $1.0 million in the first quarter of 2013.  The combined ratio for the first quarter of 2014 was 101.5% compared to 98.6% in the prior-year quarter.  Net unfavorable prior-year reserve development was $2.0 million in the first quarter of 2014 and represented 2.8 points on the combined ratio, compared to unfavorable prior-year reserve development of $1.1 million or 1.5 points on the combined ratio in the first quarter of 2013.  Losses from catastrophes were $1.4 million or 2.0 points on the combined ratio compared to $1.1 million or 1.5 points on the combined ratio in the first quarter of 2013.   This quarter’s combined ratio was also impacted by a modest increase in larger property losses that were not related to a specific identified catastrophe event.
