Thanks, Bryan.
As Bryan noted, premium grew 23% in the first quarter, which is significantly faster than the growth rate in the fourth quarter of last year. New business submissions were up around 15%, which we see as a good leading indicator. Product expansion over the last 2 years, improved customer service, geographic expansion of personal insurance and pockets of dislocation have all contributed to the growth.
Growth was widely spread with most divisions showing significant increases year-over-year. One thing that hasn't changed is our underwriting philosophy. We are still writing business with the same approach. We focus on hard-to-place business, playing careful attention to coverage, making sure that we understand the risks we are taking and that we are appropriately paid for taking them.
Overall, the market is still very competitive. Although we have seen a number of competitors experience adverse results in a few specific areas, there is still overall plenty of excess capacity in the market. When a particular competitor gets overly aggressive, that invariably leads to them experiencing some adverse results later, which, in turn, forces them to pull back. When that happens, sometimes, there will be another competitor willing to take on that same business at the same inadequate prices. But at other times, there's not. Hence, we see small pockets of dislocation modestly helping our growth rate.
Eventually, market forces will dictate, and prices will appropriately reflect the risk. But some of the behavior we are still seeing in the market is unsustainable and will have to be corrected at some point. This leads me to conclude that we will see more dislocation in the market in the future, which we regard as a good thing.
One last comment about growth. We're obviously quite pleased with 23% growth. But investors should remember that given our size, the growth rate will naturally have some variability in it, and it would be a mistake to conclude the 23% growth is the new normal based solely on one quarter's results. In any given quarter, we can't know for certain what the growth rate will be. But long term, given the advantages of our business model, we are confident we will grow the business and take market share from our competitors.
Now moving on to rates. We did not make any changes to technical rates in the first quarter. We anticipate we will make changes selectively beginning in the second quarter. I would expect the overall effect of our rate changes this year to be very modestly upward low single digits, but that will depend on how experience develops and what trends we see in the market.
And with that, I'll turn it back over to Mike.
