Thank you, Sean. Good morning, everyone, and welcome to the Donegal Group conference call for the first quarter ended March 31, 2014. As introduced, I'm Jeff Miller, Chief Financial Officer, and I will begin today's call with some comments on our quarterly financial results. Don Nikolaus, President and Chief Executive Officer, will then provide comments on the quarter and discuss our current business trends. Kevin Burke, our Chief Operating Officer, is also present on the call this morning.
You should be aware that certain statements made in our news release and in this conference call are forward-looking in nature and involve a number of risks and uncertainties. Please refer you to our news release for more information about forward-looking statements. Further information on risk factors that could cause actual results to differ materially from those projected in the forward-looking statements is available in the report on Form 10-K that we submitted to the SEC for 2013. You can find a copy of our Form 10-K in the Investors section of our website under the SEC Filings link. Further, reconciliation of non-GAAP information as required by SEC Regulation G was provided in our news release, which we have also made available in the Investor Relations section of our website.
Turning to the first quarter. Unfortunately, the severe winter weather across our operating regions disrupted the positive trends in underwriting results that we have been working hard to perpetuate. I'll provide more details in a minute about the weather and the higher-than-usual fire losses that contributed to a statutory combined ratio of 103.2% for the quarter. But outside of the unusual weather-related losses, our core underwriting results showed a continuation of the favorable trends we experienced in 2013. Our casualty lines performed well, and our non-weather loss ratios were well within our expectations. Further, our net premiums written rose 9.1% for the quarter, and we continue to pursue quality premium growth in all of our insurance subsidiaries.
Similar to prior periods, the 3 major drivers of the premium growth were premium rate increases in most of our business lines, commercial lines new business growth, and as we reported previously, another reduction in Michigan Insurance Company's external quota share reinsurance agreement. We expect the Michigan reinsurance change to add a further $10 million to our net premiums written in 2014, similar to the benefit from reinsurance reductions in the past 2 years. It also bears mentioning that net premiums written and earned in the quarter were reduced by $2 million of catastrophe reinsurance reinstatement premiums.
To give you a better sense of the quarterly loss activity, I'll walk you through the various details.
Let's begin with the weather losses. Widespread and sustained subfreezing temperatures were the Polar Vortex, as it was called, contributed to water damage from frozen pipes in many areas of the country in early January and again, later in that same month. Then numerous snow and ice storms in February contributed to car accidents and property damage claims from ice dams and roof collapses due to the weight of ice and snow.
Our total weather losses of $15.3 million were more than double the $6.9 million average from first quarter weather losses we experienced in the previous 5 years. Among the losses were those from 2 designated catastrophe events. They were the January deep-freeze and a weather system in mid-February that dumped large accumulations of snow in the Mid-Atlantic and Midwest. Our losses from those 2 events were limited by reinsurance, but many of the weather losses we sustained during the quarter were related to more isolated snow, ice and wind events across our operating regions throughout January and February.
Large fire losses of $10.1 million were higher than our normal range, exceeding the also above average $8.1 million from last year's first quarter. The increased activity was primarily within our Homeowners line of business, where we saw more fires related to additional stress on heating systems, chimney fires, et cetera, related to the unusually called temperatures.
On a brighter note, our Worker's Compensation line of business performed very well during the quarter, likely benefiting to some degree from fewer hours worked by contractors due to the weather. Likewise, the combined ratios for our Automobile lines of business improved over the prior year quarter in spite of an increased number of weather-related collision losses, which underscores the improved trends within the casualty portion of those lines of business.
Finally, there was virtually no impact from prior accident year loss reserve development on the first quarter of 2014 compared to $1.8 million of unfavorable loss reserve development in the first quarter 2013.
Because it reflects only 3 months of activity, we generally make few comments about the first quarter loss development, but we are certainly pleased that the trend appears to be heading in the right direction.
In summary, had we not experienced unusual weather and fire losses, our underwriting performance would have reflected the favorable trends we experienced in 2013, which gives us optimism that we have the ability to generate favorable underwriting results throughout the remainder of 2014.
Turning briefly to investment income. We reported a decrease of 4.1% for the quarter, mainly as a result of lower average investment yields in our fixed maturity portfolio. During the quarter, we put to work some of the cash and short-term investments that we were holding at year end, buying corporate and mortgage-backed fixed maturities, as well as a modest amount of dividend-paying equity securities. We believe that we are well-positioned to take advantage of rising interest rates should they materialize over the next few years.
Our book value per share increased to $15.18 at March 31, 2014, up from $15.02 at year end 2013, primarily due to market interest-rate-driven unrealized gains in our bond portfolio.
Last week, we announced an increase in our quarterly dividend rate. Our Board of Directors declared cash dividends of $0.1315 per share of our Class A stock and $0.1160 per share of our Class B stock payable May 15 to stockholders of record as of the close of business on May 1.
At this point, I'll turn the call over to Don for his comments on the quarter. Don?
