Chubb increased its aggregate ownership interest in Huatai Group to approximately 87.2% in the second quarter of 2025 by closing on incremental ownership interests of approximately 1.6%. This reflects a continued commitment to its strategic partnership (Note 2, Page 9).

P&C net premiums written saw robust organic growth, with commercial insurance up 3.6% and consumer insurance up 11.9% in constant dollars for Q2. International life operations, particularly in Asia, also showed strong growth of 17.8% in constant dollars, driven by new business (Page 63, 75, 79).

Despite higher catastrophe losses for the six months ended June 30, 2025 ($2,271 million vs $1,015 million in 2024), the P&C combined ratio excluding catastrophes and prior period development (CAY combined ratio ex CATs) improved to 82.3% from 83.4% for the six months, reflecting underlying loss ratio improvement and expense management (Page 65, 67).

Chubb reported pre-tax net favorable prior period development (PPD) of $249 million for the three months and $504 million for the six months ended June 30, 2025. This indicates effective reserve management and better-than-expected loss emergence in various lines, including workers' compensation and surety (Page 65).

Net cash flows from operating activities decreased to $5,117 million for the six months ended June 30, 2025, from $7,299 million in the prior year period. This decline was primarily driven by higher net losses paid and increased income taxes paid, partially offset by higher net investment income (Page 7).

Net catastrophe losses for the six months ended June 30, 2025, dramatically increased to $2,271 million, up from $1,015 million in the prior year period. This substantial rise was primarily driven by $1.47 billion in California wildfire losses (Page 65).

The company continues to hold significant unrealized losses on its fixed maturities portfolio, totaling $3,474 million at June 30, 2025. These losses are primarily attributed to rising interest rates since the date of purchase, impacting the fair value of available-for-sale securities (Page 11, 12, 82).

The company reported strong new business in casualty lines, continued strong middle market P&C growth, and acceleration of its excess and surplus (E&S) digital business, indicating competitive strength and potential market share gains in these areas (Page 63).

Growth in P&C premiums was supported by positive rate and exposure increases across all lines in consumer insurance and strong new business in casualty lines within commercial insurance, suggesting the company maintains pricing power in a competitive market (Page 63).

The acquisition of Liberty Mutual's P&C businesses in Thailand and Vietnam, alongside increased ownership in China's Huatai Group, demonstrates Chubb's strategy to expand its global reach and competitive footprint, particularly in high-growth Asian markets (Note 2, Page 9).

The P&C combined ratio improved by 1.2 percentage points to 85.6% for the three months ended June 30, 2025, compared to 86.8% in the prior year. This improvement indicates enhanced operational efficiency in underwriting, contributing to better profitability (Page 67).

The administrative expense ratio for North America Personal P&C Insurance improved by 0.9 percentage points to 4.9% for the three months ended June 30, 2025, from 5.8% in the prior year, reflecting effective expense management and higher net premiums earned (Page 71).

Chubb noted acceleration in its excess and surplus (E&S) digital business as a driver of commercial lines growth. This suggests successful digital transformation efforts are contributing to new business and market expansion (Page 63).

While the company mentions leveraging technology, the 10-Q does not provide specific line items or detailed figures for R&D investments or new technology development projects, making it difficult to quantify the scale of innovation spending (Page 5, 63).
