Thank you, Allen, and good morning, everyone. I'll make a few comments about our operational performance and trends before turning things over to Janelle to present a summary of our financials. From an operating standpoint, we had a good third quarter, generating a combined ratio of 98.5 versus combined ratios of 103.8 in the second quarter and 102.3 in last year's third quarter.
Our third quarter was highlighted by a 17.6% year-over-year increase in gross premiums written, our seventh straight quarter of double-digit year-over-year increases. As has been the case throughout 2012, the third quarter increase was due to 2 factors. First, we showed a 16.6% year-over-year increase in premium from policies written during the quarter, which we refer to as dec sheet premium. Our third quarter dec sheet premium increase was the highest quarterly increase in our public company history. And it occurred during a period of continuing increases in our pricing, clear confirmation that the overall work comp market is hardening.
The second factor in the increase in our gross premiums written was a 22.9% increase in payroll audits and related premium adjustments. Regarding payroll audits specifically, we experienced an 18.8% increase over the year ago quarter, and we are frankly surprised that audits have continued to be a top line tailwind for us. We wouldn't have expected this trend, now 8 quarters long, to be as prolonged as it has been. These year-over-year quarterly increases in audits will eventually come to an end. But for now, we're happy to benefit from them. In terms of pricing, our effective loss cost multiplier for voluntary work comp written in the third quarter was 1.66, or 166% of the approved loss cost in the states that use this mechanism for pricing. This pricing represents a year-over-year increase of almost 11% and is the highest level we have seen since we began calculating this metric. Our increased pricing has also contributed to an increase of over 20% in our average renewal premium, which has in turn, led to a substantial increase in our third quarter premium retention from 86.8% in Q3 '11 to a very robust 102% in Q3 '12. In terms of policy retention, we experienced a small year-over-year decrease in the 2012 third quarter to 191.2% from 92.7% in the third quarter of '11.
Regarding losses, we are seeing some positive signs for accident year '12 including decreasing claim frequency, both payroll and premium-based, decreased reported indemnity claims and increased closure rates. But 2012 is still very green, so we have maintained our net current accident year loss in LAE ratio at 76.5%.
We are especially pleased to see our frequency measures decreasing and even more pleased that the decrease is attributed not only to increasing rates, but to increasing exposures and decreasing reported claims as well. Relative to prior years, we experienced stabilizing development in the third quarter relative to prior accident years resulting in a lowering of our overall ultimate loss in LAE estimate for these prior years by $1.6 million in the aggregate.
In her comments, Janelle will provide further color around our loss ratio and its components. In terms of severe loss experience, we have not seen the proliferation of large claims in 2012 that we have experienced in prior years. Our largest loss year-to-date totals only $1.98 million. We are pleased with this result. But as Allen and I have said repeatedly, we are in a lumpy and unpredictable business providing coverage to very dangerous occupations. And one never knows when a catastrophic loss might occur.
For now though, we can say that 2012 has had a good 3 quarters of severe loss experience. As I mentioned earlier, our claims closure rate was up again in the third quarter. All 3 quarters of 2012 have now had increased closure rates.
Finally, our paid to incurred ratio decreased for the second straight quarter in 2012, which we view as an indicator of possible case reserve strengthening.
Overall, I can say that I'm very pleased with our third quarter operating results. And with that, I'll turn the discussion over to Janelle for details regarding our financial performance.
