Operational Performance

All the segments posted year-over-year improvement in premiums.

Underwriting income was $24.7 million, up 13.8% year over year. An almost three-fold increase in underwriting income at Casualty, partially offset by an underwriting loss at Property, aided the improvement.

Investment income declined 4.8% year over year to $16.0 million attributable to lower reinvestment rates. The investment portfolio’s total return for the quarter was flat compared to the prior year quarter; the return in the bond portfolio was 2.4%, while the equity portfolio was negative 10%.

Revenue in the quarter under review totaled $162.3 million, up 8.5% from $149.6 million in the prior-year quarter, driven by higher premiums earned. Revenue also topped the Zacks Consensus estimate of $148 million.

Total expenses during third-quarter 2011 were $124.9 million, up 13.3% year over year. The increase was primarily driven by higher loss and settlement expense and higher policy acquisition costs.

Combined ratio in the third quarter was 83.1%, flat with third quarter 2010. Higher combined ratio at Property was offset by lower combined ratio Casualty and Surety.

Book value was $41.16 per share as of September 30, 2011, up 9.0% from $37.75 as of December 31, 2010. The company recorded a 16.5% return on equity, with a 14.6% return on a comprehensive basis.

Our Take

The company’s underwriting discipline is also expected to bode well given the stabilization in the markets. Also, acquisitions broaden its client base and help it to write higher premiums in the upcoming quarters.

The company scores strongly with the rating agencies and remains focused to return value to its shareholders value through dividend increase and share buybacks.

We maintain our Neutral rating on RLI Corp. The quantitative Zacks #3 Rank (short-term Hold rating) on the stock indicates no clear directional pressure on the shares over the near term.
