Third quarter highlights included:

•Return on equity and operating return on equity of 19.6% and 20.0%, respectively.

•Net investment income grew 19.5% to $323.8 million compared to the prior year.

•The current accident year combined ratio before catastrophe losses of 3.3 loss ratio points was 87.6%, and the reported combined ratio was 90.9%.

•Average rate increases excluding workers' compensation were approximately 8.4%.

•Book value per share grew 10.0%, before dividends and share repurchases.

•Total capital returned to shareholders was $138.3 million, consisting of $95.3 million of special dividends, $30.5 million of regular dividends and $12.5 million of share repurchases.

•Record operating cash flow increased 15.2% to $1.2 billion.

The Company commented:

The Company reported record third quarter net income in 2024. Continued strong underwriting margins and increasing investment income drove our 19.6% annualized return on beginning of year common stockholders’ equity.

We continue to grow thoughtfully by focusing on business we expect to achieve or exceed our targeted risk-adjusted return, being ever mindful of rate adequacy, loss trend, and exposure management. Our 90.9% calendar year combined ratio again demonstrated below average volatility, with a modest 3.3 loss ratio points of catastrophe losses, despite the frequency of severe market-wide events.

Net investment income increased 19.5% over the prior year third quarter, driven by an increase in fixed-maturity income. We anticipate that the Company’s new money rate will remain above the current yield of our U.S. fixed-maturity securities, notwithstanding the recent and expected decreases in short-term rates. Coupled with increases in invested assets from continuing record cash flow, we remain well-positioned for further investment income growth.

Our success in navigating a wide variety of underwriting and investment environments has resulted in best-in-class returns on equity and below-average volatility that has generated significant shareholder value over many years. Fueled by knowledge and expertise, our decentralized structure allows us to take a flexible, proactive, and innovative approach to whatever risks and opportunities the market may present. We expect to continue to deliver outstanding risk-adjusted returns to our shareholders for the remainder of 2024 and beyond.
