In this competitive market, we expect our specialty niche focus combined with the strength of our existing platform to differentiate us from our peers. We remain committed to our objective to deliver strong results through disciplined underwriting while executing on our growth strategy. As such, we anticipate annual premiums produced growth in excess of 20 percent for 2008. Despite a forecasted decline in reinvestment rates and our continued development of new underwriting platforms, we are targeting for 2008 a return on average stockholders’ equity between 16.5 and 18.0 percent.”
