Chubb reported that its tangible book value per share, excluding accumulated other comprehensive income, climbed 10.1% to $150.70 through September 30, 2026. This metric, which filters out interest rate and currency volatility, helps operators understand the underlying equity growth of a major institutional insurer.
Why it matters
By adjusting for AOCI, Chubb provides a clearer view of its operational equity growth, a standard practice for managing balance sheet volatility. Businesses tracking insurance partners should monitor these equity trends as indicators of financial stability and capacity for future underwriting.
Chubb's tangible book value per share excluding AOCI rose to $150.70 from $136.91 at the end of 2025. This growth coincides with a $740 million investment in USI Insurance Services, which is subject to a pending $17 billion acquisition by Aon.
The players
Chubb
A global property and casualty insurer that provides commercial and personal insurance to businesses and individuals.
Aon
A global professional services firm that provides risk, retirement, and health solutions.
USI Insurance Services
A national insurance brokerage and consulting firm currently held as an investment by Chubb.
KKR
A global investment firm that partners with entities like Chubb to facilitate large-scale capital deployments.
The details
Chubb calculates tangible book value per share by removing goodwill and intangible assets from shareholders' equity before dividing by total shares. The insurer specifically excludes accumulated other comprehensive income (AOCI) to shield the metric from market-driven fluctuations in interest rates and foreign currency values. This approach provides a normalized perspective on shareholder equity separate from broader macroeconomic swings.
Timeline
December 31, 2025: Tangible book value per share stood at $136.91.
September 30, 2026: Tangible book value per share reached $150.70.
Q4 2026: Aon is expected to close its acquisition of USI Insurance Services.
Market Landscape
Chubb’s reporting strategy mirrors the broader industry trend of using non-GAAP measures to isolate operational equity from interest rate volatility. This practice highlights how major insurers navigate Generally Accepted Accounting Principles to provide clearer performance transparency to stakeholders.
Operators should monitor these equity trends as indicators of institutional financial stability when evaluating long-term insurance carriers. Firms currently utilizing services from USI Insurance Services should keep watch for leadership or policy changes once the Aon acquisition proceeds.
The takeaway
The gap between unadjusted and adjusted book value growth underscores the outsized role interest rate fluctuations play in insurance company valuations. Operators should evaluate the financial health of insurance partners using normalized metrics to separate core performance from temporary market volatility.
What happens next
Chubb expects a $460 million gain if Aon closes the acquisition of USI Insurance Services, which is projected for the fourth quarter of 2026.
