Mario Rizzo
President - Property Liability at Allstate
Thanks, Tom. Let's start on Slide 4. Property-Liability earned premium increased 10.9% in the first quarter, driven by higher average premiums. Underwriting income was $89 million, the combined ratio of 93%, which improved by 15.6 points compared to prior year was driven by higher premiums earned, improved underlying loss cost trends, lower catastrophe losses and operating efficiencies.
The chart on the right depicts the components of the 93 combined ratio. Lower catastrophe losses of $731 million were 8.8 points favorable to the prior year quarter, reflecting milder winter weather. The underlying combined ratio of 86.9% improved by 6.4 points compared to the prior year quarter. The improvement was driven by higher average premium and moderating loss cost increases. Expense reduction programs also benefited results more than offsetting higher advertising spend.
Prior year reserve re-estimates, excluding catastrophes, had only a small impact on results. favorable development in personal auto and homeowners insurance largely offset increases in personal umbrella liabilities and commercial auto reserves for the transportation network contracts we began exiting in late 2022.
Now, let's take a closer look at auto insurance profitability on Slide 5. The first quarter recorded auto insurance combined ratio of 96 improved by 8.4 points compared to the prior year quarter, showing that our profit improvement plan is working.
The left chart shows quarterly underlying combined ratios. You will remember, we showed this chart last year, which adjusts 2022 and 2023 quarterly reported figures to reflect the updated average severity estimates as of the end of each respective year.
As you can see, the underlying combined ratio improved sequentially in each of the last five quarters to 95.1% in the first quarter of 2024. The chart on the right shows that in the first half of 2023, premium increases in dark blue were being offset by higher underlying losses and expenses.
Profits began to improve in the third quarter of 2023 as premiums outpaced loss and expense increases and this continued in this year's first quarter. The slight first quarter drop in underlying loss and expense reflects lower claim frequency that benefited from milder weather and improved operating efficiencies, partially offset by higher severity.
Relative to the prior year quarter, average underlying loss and expense in the first quarter of 2024 was 6.7% higher as you can see at the top of the table. This reflects higher current year incurred severity estimates, primarily driven by bodily injury coverage, which was partially offset by lower accident frequency and the favorable impact on current year severity of favorable prior year reserve development in the Allstate brand.
Given the impact that good weather had on frequency in the quarter, favorable frequency may not persist as the year progresses. While auto margins have improved due to our price improvement actions we remain focused on ensuring that rate levels continue to keep pace with underlying cost trends driving improved profitability in those states not yet achieving target margins.
Slide six shows how auto profit improvement supports pursuing policy growth. As shown on the left, Allstate brand implemented rate increases exceeding 16% in both 2022 and 2023. In the first quarter of 2024, we implemented rate increases of 2.4% to keep up with the cost trends and improve margins in states not achieving target margins.
The chart on the right depicts the Allstate brand auto proportion of premium in states with an underlying combined ratio of below 96%, shown by the dark blue bars. As more states have achieved target returns, we have started to increase marketing investment, both nationally and in those states.
Slide seven shows that while Allstate brand policies in force decreased compared to prior year, albeit at a slower rate than last quarter, over half that decline was offset by growth at National General.
On the left, you can see that total protection auto policies in force decreased by 2% and compared to prior year due to a decline of 5.2% in the Allstate brand, reflecting the continued impact of auto insurance profit improvement actions. Underneath this decline is the positive impact of higher Allstate agent productivity and direct channel sales.
Customer retention in the Allstate brand also continued to improve, and that improvement has a significant impact on growth trends. Allstate brand auto retention of 86% improved by 0.3 points compared to prior year, as the negative impact of large rate increases in 2022 and 2023 begins to moderate.
As we discussed last quarter, we received approval for rate increases in the profit challenge states of California, New York and New Jersey, which were affected this quarter. Renewal trends in those states were stable in the first quarter, but the full impact on customer retention has not yet impacted growth. Allstate brand new business also increased 7% versus the prior year, reflecting more advertising and increased Allstate agent productivity and direct sales.
National General was another positive to growth. Policies in force increased by 12.6% over the prior year due to an increase in nonstandard auto insurance and the continued rollout of a new middle market standard and preferred auto insurance product, also known as Custom 360.
Slide eight summarizes homeowners insurance profitability, which generated strong returns in the quarter. Homeowners insurance provides a differentiated customer experience and represents an additional growth opportunity across channels. The chart shows the homeowners combined ratio over time, achieving a 10-year average of approximately 92%.
The first quarter combined ratio of 82.1% translated to $564 million of underwriting income and improved 36.9 points compared to prior year, primarily driven by lower catastrophe losses. The underlying combined ratio of 65.5% also improved by 2.1 points due to higher average premium and lower non-catastrophe claim frequency.
Allstate Protection homeowners generated double-digit written premium growth compared to prior year. reflecting higher average gross written premium per policy and policies in force growth of 1.4%.
Allstate agents continue to bundle auto and homeowners insurance at historically high levels. and National General's Custom 360 product offers additional growth opportunities in the independent agent channel. Allstate has created an industry-leading business model, and we remain confident in our ability to generate attractive risk-adjusted returns.
Moving to Slide 9, let's discuss the property liability growth opportunities. Starting on the first row. Improving customer retention remains key to improving our growth trajectory. Auto retention levels have stabilized and sequentially improved over the last two quarters and homeowners retention improved 0.8 points to the prior year quarter.
Our agents and employees continue to guide customers through the renewal process by offering coverage options and ways to save through innovative programs and discounts like Drivewise and Milewise telematics offerings. Growth can also be increased by easing new business restrictions.
As rate adequacy has been achieved in more states, restrictive underwriting policies have been unwound in states representing more than 75% of Allstate brand auto premium.
Increased Allstate brand advertising is also expected to increase growth. The components of transformative growth are being implemented to create sustainable growth. An improved competitive position will result from further expense reductions.
Expanded customer access comes from increased Allstate agent productivity enhanced direct distribution and the expansion of custom 360 to more independent agents. A new Allstate brand, affordable, simple and connected auto insurance product is available in nine states on the direct sales side.
Online quote completion time has been reduced by 40% to less than three minutes within the new technology ecosystem. This platform will be expanded to the Allstate agent channel this year into more states and homeowners over the next several years. With these growth levers, Allstate is positioned to generate sustainable, profitable growth.
Now, I'll turn it over to Jesse to talk about other operating results.
