Stephen M. Spray
President and Chief Executive Officer at Cincinnati Financial
Good morning, and thank you for joining us today to hear more about our results.
Our hearts go out to those impacted by the LA wildfires. You've lost homes, treasured belongings, a sense of community, and in the most devastating cases, loved ones. I also want to thank the first responders who put their lives on the line, our agents for their support and partnership, and of course, our claims associates who are working tirelessly to help our policyholders with immediate needs and longer-term plans.
Before I share more details about our current estimate for this catastrophe, let's dive into how we performed last year. Operating performance for the 4th-quarter was very strong and many key areas showed improvements. We are also pleased with performance for full-year 2024, thanks to the superb work of our associates providing service to agents who we consider to be the best-in the insurance business. Our 4th-quarter results compared to the same-period last year included a better combined ratio and excellent growth in premiums and investment income. The result boosted net income and we had double-digit growth in operating income.
Net income was $405 million for the 4th-quarter of 2024. It included recognition of $107 million on an after-tax basis for the decrease in fair-value of equity securities still held. An unfavorable swing of $931 million from the same-period a year-ago. Net income for the year rose 24%. Non-GAAP operating income for the quarter increased 38% to $497 million and rose 26% for full-year 2024. Our 84.7% 4th-quarter 2024 property-casualty combined ratio was 2.8 percentage points better than a year-ago. It brought the full-year combined ratio to an outstanding 93.4%, 1.5 points better than 2023. The full-year improvement included a catastrophe loss ratio effect only 0.2 points lower.
Our 86.5% accident year 2024 combined ratio before catastrophe losses improved by 1.9 percentage points compared with accident year 2023, including 5 points of improvement for the 4th-quarter. First, we reported another quarter of strong premium growth. We believe it's profitable growth as our underwriters diligently use pricing precision tools to support their risk segmentation efforts on a policy-by-policy basis. For example, estimated average renewal price increases for the 4th-quarter were similar to the 3rd-quarter of 2024. Commercial lines moved slightly lower in the high single-digit percentage range and excess and surplus lines remained in the high single-digit range.
Our Personal Lines segment was also similar to the 3rd-quarter with personal auto in the low double-digit range and homeowner in the high single-digit range. New business growth produced by agencies representing Cincinnati Insurance continued at a nice pace. Nearly one-third of the growth for the year was from agencies appointed since the beginning of 2023, reflecting our strategy of appointing additional agencies where we identify appropriate expansion opportunities. Policy retention rates in 2024 were similar to last year with our Commercial Lines segment up slightly, but still in the upper 80% range. Our Personal Lines segment remained in a similar position of the low-to mid 90% range.
The overall result was consolidated property Casualty net written premiums growth are growing 17% for the quarter, including 15% growth in agency renewal premiums and 23% in new business premiums.
Next is a brief review of performance by insurance segment for full-year 2024 compared with 2023. Most -- most metrics also improved on a 4th-quarter basis. Commercial lines grew net written premiums 8% with an excellent combined ratio that improved by 3 percentage points to 93.2%. Personal Lines grew net written premiums 30% and improved the combined ratio by 2.9 percentage points to 97.5%. Access and surplus lines grew net written premiums 15% with a 94.0% combined ratio. Although that was 3.4 percentage points higher than last year, it's still quite profitable. Both Cincinnati Re and Cincinnati Global were also very profitable.
Cincinnati re grew net written premium 7% with an 85.0% combined ratio, while Cincinnati Global's growth was 8% with a 73.6% combined ratio. Our life insurance subsidiary also improved its results with a 21% increase in 2024 net income and term life insurance earned premium growth of 3%. These strong results combined to bring our value-creation ratio in above our target of 10% to 13% on a five-year average basis. Our 4th-quarter DCR was 1.8% and we reached 19.8% on a full-year basis. Net income before investment gains or losses for the year contributed 9.9%, higher overall valuation of our investment portfolio and other items contributed the other half.
Before I turn the call over to Mike, I'll provide our current estimates of financial effects related to the recent California wildfires and an update on our 2025 reinsurance program.
We estimate first-quarter 2025 pre-tax catastrophe losses of approximately $450 million to $525 million, net of reinsurance recoveries. That includes approximately 73% for our Personal Lines Insurance segment, 24% for Cincinnati Re, and 3% for Cincinnati Global. We reinstated the applicable layers of our primary property catastrophe reinsurance treaty coverage and will cede additional premiums to our reinsurers. Cincinnati Re will receive additional premiums from treaties reinstated. The estimated net effect of first-quarter premium revenue is a decrease of $50 million to $60 million.
To keep this event in perspective, had the wildfire effect occurred in 2024, we believe we would still have earned a modest underwriting profit. On January 1 of this year, we again renewed each of our primary property-casualty treaties that transfer part of our risk to reinsurers. For our per-risk treaties, we increased our retention for the property treaty to $15 million while retention for the casualty treaty remained at $10 million.
Other terms and conditions for 2025 are fairly similar to 2024. The primary objective for our property catastrophe treaty is to protect our balance sheet. The treaty's main change this year is adding another $300 million of coverage, increasing the top of the program from $1.2 billion to $1.5 billion. We again retain all of the first $200 million, then retain 56% of the next $100 million, 25% of the next $100 million and approximately 14% of the next $1.1 billion.
Now let me turn the call over to Chief Financial Officer, Mike Sewell, for additional highlights of our financial performance.
