I. Executive Summary & Investment Thesis

The Chubb Corporation (CB) stands as a premier global property and casualty (P&C) insurance organization, distinguished by a deeply ingrained culture of underwriting discipline that has consistently generated superior, less volatile returns relative to its peers. The company’s operational prowess is not an end in itself but rather the engine that funds a multi-faceted strategy for long-term value creation. This strategy is centered on three core pillars: maintaining best-in-class underwriting profitability, executing large-scale strategic acquisitions to diversify into higher-growth geographic and product markets, and compounding capital through a conservatively managed yet increasingly opportunistic investment portfolio.

The central investment thesis for Chubb is that it represents a best-in-class operator leveraging its core underwriting profitability to transform its business profile. The consistent generation of underwriting profits provides a low-cost source of capital, or “float,” which fuels two powerful growth vectors. The first is a strategic pivot towards the secular growth trends in Asia, executed through the landmark acquisitions of Cigna’s Asia-Pacific life and health businesses and a controlling stake in China’s Huatai Insurance Group. These moves diversify Chubb’s revenue streams, reduce its dependency on the mature U.S. P&C market, and lessen the volatility associated with the traditional underwriting cycle. The second vector is the compounding growth of its substantial investment portfolio. In the post-2022 higher interest rate environment, this portfolio has transformed from a stable contributor into a primary engine of earnings growth, a trend management is amplifying through a strategic increase in allocation to higher-yielding private assets.

Key opportunities for the company include the potential for sustained underwriting margin outperformance, which creates a virtuous cycle of excess capital generation for reinvestment and shareholder returns. The successful integration of and cross-selling opportunities from the Cigna and Huatai acquisitions present a long-term, accretive growth pathway in Asia. Furthermore, a significant, built-in tailwind for Net Investment Income (NII) growth exists as the company’s strong cash flows are reinvested at higher prevailing rates. Chubb’s proactive adaptation to emerging risks, such as climate change and cyber threats, through dedicated business units also presents an opportunity to establish market leadership and create new revenue streams.

Conversely, significant risks temper the outlook. As a global property insurer, Chubb has material exposure to the increasing frequency and severity of natural catastrophe events, which could challenge profitability despite sophisticated risk modeling. There is inherent integration risk associated with large-scale acquisitions in foreign markets that possess distinct regulatory and cultural environments. A cyclical downturn into a more competitive “soft” P&C market could pressure pricing and margins across the industry, although Chubb’s disciplined approach provides a degree of insulation. Finally, its significant and growing international presence, particularly its substantial new investment in China, exposes the company to heightened geopolitical risks.

II. Business Model & Industry Landscape

A. The Chubb Underwriting Engine: A Cultural Moat

At its core, Chubb defines itself as “first an underwriting company, dedicated to the art and science of taking risk”.1 This principle is the foundation of its business model and a primary source of its competitive advantage. The company’s approach to assessing, assuming, and managing risk is characterized by a culture of “insight and discipline”.2 This is not merely a passive stance but an active, agile strategy. Management’s philosophy is to be “patient in long-term strategy and impatient in execution”.1 This was demonstrated in the years leading up to 2019, when Chubb strategically reduced its exposure in inadequately priced business lines. When market conditions turned favorable and competitors who had underpriced risk were forced to pull back, Chubb rapidly shifted from a defensive to an offensive posture, leveraging its balance sheet strength to capture market share at attractive terms.3

This disciplined underwriting consistently produces profits from the company’s core insurance operations, a feat many competitors struggle to achieve. The ability to maintain a P&C combined ratio—the sum of incurred losses and expenses divided by earned premium—well below the 100% breakeven point is a critical differentiator. For an insurer, this underwriting profit means that the “float”—premiums collected from policyholders that are held for investment before claims are paid—is generated at a negative cost. This profitably generated float becomes a powerful, internally-generated source of capital that can be deployed into the investment portfolio or used to fund strategic initiatives like M&A. This creates a compounding effect on shareholder value that is difficult for less disciplined peers, who may rely solely on investment income for profits, to replicate. It is this underwriting engine that powers the entire enterprise.

Integral to this process is a robust claims management capability. The company emphasizes its commitment to servicing and paying claims “fairly and promptly”.2 This approach is crucial for customer retention and reinforces the premium brand reputation, particularly within its key client segments of high-net-worth individuals and large multinational corporations.

B. Diversified Global Portfolio: Balancing Risk and Growth

Chubb operates a well-balanced and globally diversified portfolio of insurance businesses, which mitigates its reliance on any single product line, customer segment, or geographic region. The business mix is split between commercial and consumer lines, with approximately 62% of revenue derived from insuring businesses and 38% from insuring individuals as of 2023.4 The company’s product suite is extensive, covering more than 200 distinct property and casualty-related products.4

The company’s geographic footprint is truly global. With operations in 54 countries and territories, Chubb is one of the few true insurance multinationals.2 While it is the largest commercial P&C insurer in the United States, a significant portion of its business originates internationally. In 2023, 60% of total company premium revenue came from outside its North America commercial division.4 The geographic distribution of net premiums written in 2022 was approximately 61% from the United States, 14% from Asia, 13% from Europe, and 6% from Latin America.3

Recent strategic acquisitions have further enhanced this diversification. The 2022 acquisition of Cigna’s personal accident, supplemental health (A&H), and life insurance businesses in Asia significantly expanded Chubb’s presence in the region and deepened its capabilities in consumer lines.5 Following this and other investments, Asia’s contribution to the company’s global insurance business is now approaching 20%.3 This strategic expansion into life and A&H insurance adds a stream of long-duration, high-margin earnings that is not correlated to the P&C underwriting cycle, thereby enhancing the stability and predictability of the company’s overall earnings profile.

C. The P&C Underwriting Cycle: Navigating Market Dynamics

The P&C insurance industry is inherently cyclical, characterized by periods of intense price competition (a “soft market”) and periods of rising premiums and stricter underwriting standards (a “hard market”). Recent industry analysis suggests the market is stabilizing after several years of hard market conditions. S&P Global projects that the industry-wide combined ratio will likely hover between 98% and 100% for 2024 and 2025, indicating that the average insurer will generate only marginal, if any, profit from its core underwriting activities.7

Current pricing trends within the industry are bifurcated. After several years of significant rate increases, pricing in commercial property lines is beginning to decelerate. Conversely, pricing in casualty lines is accelerating, driven by concerns over “social inflation”—the trend of rising claims costs due to larger jury awards and more aggressive litigation.8 The aggregate effect was a slight decline in overall U.S. commercial insurance prices in the first quarter of 2025, the first such decline since 2018.8

Chubb’s consistent underwriting outperformance positions it to navigate this complex environment from a position of strength. The company’s ability to generate a combined ratio in the mid-80s (86.6% in 2024) 9 provides a substantial profitability cushion that is unavailable to the average carrier. Management has demonstrated a willingness to prioritize profitability over top-line growth, walking away from aggressively competitive lines like professional liability while capitalizing on firming conditions in areas like property insurance.10

This persistent performance gap suggests that Chubb’s profitability is becoming increasingly decoupled from the broader P&C cycle. While the industry struggles to break even on underwriting, Chubb has consistently maintained a highly profitable book of business. This resilience stems from its leadership position in specialized and less commoditized markets, such as high-net-worth personal lines and complex commercial risks, where its expertise and service command superior pricing. Furthermore, the growing contribution from its non-cyclical Life and A&H businesses, particularly after the Cigna acquisition, will further insulate consolidated earnings from P&C pricing volatility.6 This points toward a more durable and predictable earnings stream than that of a pure-play P&C carrier, which typically warrants a higher valuation multiple from the market.

III. Competitive Positioning & Economic Moat

A. Market Leadership & Share

Chubb holds a formidable market position across several key insurance segments, underpinned by its significant scale and global reach. In the critical U.S. market, Chubb is the second-largest writer of commercial lines insurance by direct premiums written, commanding a 5.2% market share, which places it in a virtual tie for the top position with The Travelers Companies, Inc..12 The company’s leadership is even more pronounced in specific niches; it is the number one insurer for large corporations, crop insurance, and high-net-worth personal lines in North America.13

In the rapidly growing and technically complex field of cyber insurance, Chubb has established itself as the clear market leader in the United States, holding an 8% share of admitted direct written premiums in 2024.14 This leadership position in an emerging risk category highlights the company’s ability to innovate and deploy its underwriting expertise to new challenges.

Globally, Chubb’s scale is a significant differentiator. With a market capitalization exceeding $100 billion and operations spanning 54 countries, it is one of a select few P&C insurers with a truly global, integrated network capable of serving the largest multinational clients.2

B. Sources of Competitive Advantage (The Moat)

Chubb’s sustained success is protected by a wide and deep economic moat built on several mutually reinforcing competitive advantages.

  • Brand and Reputation: The Chubb brand is a powerful asset, synonymous with financial strength, superior service, and expert claims handling. This reputation is particularly valuable in the high-net-worth personal lines and large corporate segments, where clients are willing to pay a premium for the assurance of coverage and service quality in the event of a complex loss.15
  • Distribution Network: A cornerstone of Chubb’s moat is its vast, multi-channel distribution network. The company maintains relationships with an extensive network of 50,000 independent agents and brokers, hundreds of thousands of exclusive life and health agents, and over 200 direct-to-consumer digital partners.1 This diverse network provides unparalleled access to a wide range of customer segments and markets globally, making it difficult for competitors to replicate.
  • Underwriting Expertise and Data: With a corporate history tracing back to 1882, Chubb has accumulated a deep reservoir of underwriting data and expertise across hundreds of product lines.17 This historical data, combined with sophisticated analytical and catastrophe modeling techniques, allows for more precise risk selection, pricing, and portfolio management than can be achieved by smaller or newer competitors.18
  • Scale and Diversification: The company’s immense scale and diversification provide numerous advantages. Its strong capital base allows it to retain more risk and take meaningful positions on large, complex accounts that smaller insurers cannot. The global and product diversification enables it to absorb large losses in one area while remaining profitable overall, and to strategically allocate capital to the most attractive markets and opportunities as they arise.4

C. Navigating Competitive Threats

Chubb operates in a highly competitive landscape, facing threats from large, diversified global insurers such as AIG, Allianz, and Travelers, as well as disciplined specialty carriers like Markel and Berkshire Hathaway.19 In addition to these traditional rivals, the industry faces disruption from a new wave of technology-focused startups, or “insurtechs.”

Chubb’s strategic response to the insurtech threat is particularly noteworthy. Rather than attempting to build a standalone, consumer-facing digital brand to compete directly with these new entrants, Chubb has adopted a strategy of becoming the technology and risk-capital partner of choice for other companies through its Chubb Studio platform.16 Chubb Studio is a proprietary technology platform that provides a suite of APIs (Application Programming Interfaces) allowing partners to seamlessly embed Chubb’s insurance products into their own digital ecosystems and customer journeys.16

This approach effectively creates an “Intel Inside” model for the insurance industry. It leverages Chubb’s core strengths—its strong balance sheet, broad product manufacturing capabilities, and global licensing—while turning potential disruptors into valuable distribution channels. This B2B2C (Business-to-Business-to-Consumer) model is highly scalable and creates a low-cost customer acquisition engine by tapping into the established user bases and brands of its partners. A prime example is the partnership with NuBank, the world’s largest neobank, to offer in-app insurance to over 40 million customers.16 This strategy allows Chubb to access new, digitally native customer segments without incurring the massive marketing and brand-building expenses that would be required to do so directly. It is a sophisticated maneuver that transforms a competitive threat into a strategic opportunity.

IV. Financial Performance & Analysis

A. Underwriting Profitability Deep Dive

Chubb’s financial performance is anchored by its consistent and superior underwriting profitability. The company has delivered a remarkably stable P&C combined ratio through a period marked by significant macroeconomic and industry challenges, including the COVID-19 pandemic, multi-decade high inflation, and elevated catastrophe losses. The P&C combined ratio was 86.6% in 2024, 86.5% in 2023, and 87.6% in 2022.3 This level of performance is a gold standard in the industry.

This is not a recent phenomenon. Over multiple time horizons—3, 10, and 20 years—Chubb’s combined ratio has consistently outperformed its peer group average by a significant margin of 6 to 8 percentage points.13 This demonstrates a structural underwriting advantage rather than a temporary or cyclical benefit.

A key contributor to this outperformance is the company’s operational efficiency. Chubb operates with a P&C expense ratio of approximately 26.2%, which management describes as a “meaningful and enduring advantage”.26 This lower cost structure, combined with disciplined risk selection and pricing, provides a direct and sustainable benefit to its underwriting margin and overall profitability.

B. The Investment Portfolio Engine

The second pillar of Chubb’s earnings power is its large and conservatively managed investment portfolio. As of year-end 2024, total invested assets stood at $151 billion.40 The portfolio is predominantly allocated to fixed-income securities, which comprise 89% of the total, with the vast majority of these holdings rated investment-grade with an average rating of ‘A’.4 The remaining 11% is invested in alternative asset classes, primarily private equity and credit.40

The rising interest rate environment since 2022 has been a powerful tailwind for Chubb, transforming the investment portfolio into a primary engine of earnings growth. Adjusted net investment income grew by an impressive 33% to $5.3 billion in 2023 and a further 19.3% to a record $6.4 billion in 2024.4 This represents a 59% increase in just two years.26 This growth is driven by the reinvestment of the company’s strong operating cash flows at higher prevailing interest rates. For example, during the fourth quarter of 2022, the company’s new money reinvestment rate was averaging 5.6%, significantly higher than the then-current portfolio yield of 3.6%.11 This positive differential creates a natural and ongoing uplift to investment income as older, lower-yielding bonds mature and are replaced.

This favorable environment has unlocked a second growth engine for the company. While low rates for the preceding decade had rendered investment income a stable but low-growth contributor, the post-2022 environment has changed this dynamic. Management is proactively capitalizing on this shift. The strong operating cash flow generated by the underwriting business ($15.9 billion in 2024) 9 is being deployed not only into higher-yielding bonds but also into a strategically larger allocation to private, less-liquid assets. The company plans to increase its allocation to this category from 11% to approximately 15% of the portfolio.40 These assets have historically generated superior returns, with a 14.5% internal rate of return (IRR) and an 8% cash yield.40 This proactive portfolio management is designed to lock in a higher base of earnings for the future, providing a durable tailwind to profitability.

C. Returns and Balance Sheet Strength

The combination of strong underwriting results and accelerating investment income has translated into excellent returns on capital and robust balance sheet growth. For the full year 2024, Chubb generated a core operating return on equity (ROE) of 13.9% and a core operating return on tangible equity (ROTE) of 21.6%.9

Growth in book value per share, and particularly tangible book value per share, serves as a primary measure of long-term value creation for shareholders. The company has delivered strong growth on this front. Tangible book value per share increased by 21.3% during 2023.41 As of the end of the second quarter of 2025, tangible book value per share stood at $112.64.37 This consistent compounding of tangible value underscores the quality of the company’s earnings and its disciplined capital management.

Chubb’s balance sheet is a source of significant strength. At the end of 2024, the company had total assets of $247 billion and total shareholders’ equity of $64 billion.5 Its financial strength is recognized by major rating agencies, with its core operating companies carrying ratings of “AA” from S&P and “A++” (Superior) from A.M. Best, the highest rating available.42 This strong capital position supports the company’s risk-taking capacity and provides the financial flexibility to pursue strategic growth opportunities.

V. Growth Strategy & Management Execution

A. Organic Growth Drivers

Chubb has a proven ability to generate strong organic growth, driven by its strong market position and expansion initiatives. Consolidated net premiums written grew by a robust 13.5% in 2023, followed by Global P&C premium growth of nearly 10% in 2024.4 This growth has been well-balanced, with commercial lines growing 8.7% and consumer lines growing 13.3% in 2024, demonstrating broad-based strength across the portfolio.26

A key component of the company’s organic growth strategy is its focus on emerging markets. Management has explicitly identified Asia and Latin America as priority regions for expansion in both P&C and consumer lines.13 Chubb has already established a leadership position in these regions as the number one direct marketer of Accident & Health (A&H) insurance.13 The strategy involves leveraging the company’s global capabilities, product expertise, and technology while maintaining a deep local presence to tailor offerings to specific market needs.4 This approach is designed to capture the growth driven by the expanding middle class and increasing insurance penetration in these economies.

B. Inorganic Growth: A Strategic Pillar

Mergers and acquisitions are a core competency and a central pillar of Chubb’s long-term strategy. The company is one of the most acquisitive insurers globally, having successfully executed and integrated approximately $47 billion in transactions over the last 18 years.13 Recent M&A activity reveals a deliberate, multi-billion-dollar strategic pivot to re-position the company for future growth.

  • Cigna Asia Acquisition (Completed July 2022): Chubb acquired Cigna’s A&H and life insurance businesses across six Asia-Pacific markets for $5.36 billion.6 This transaction immediately increased the Asia-Pacific region’s share of Chubb’s portfolio to approximately $7 billion in annual premiums.6 The strategic rationale was multi-faceted: it provided a significant increase in scale in a high-growth region, and it added a substantial book of high-margin, non-cyclical A&H and life business. This diversification reduces the volatility of Chubb’s consolidated earnings by lessening its dependence on the traditional P&C cycle.6 The deal was expected to be immediately accretive to earnings per share and ROE, with projected expense synergies at a run-rate of $100 million, which was higher than initial estimates.6
  • Huatai Group Acquisition (Majority Control in 2023): After a persistent 20-year effort, Chubb received regulatory approval to increase its ownership stake in Huatai Insurance Group to 83.2%.46 This made Chubb the first foreign financial institution to gain majority control of a Chinese financial services holding company, which has distinct P&C, life, asset management, and mutual fund subsidiaries.46 This transaction provides Chubb with unprecedented access to China’s vast and rapidly growing insurance market, which is the second-largest in the world.46 Management views this as a long-term strategic investment, expecting Huatai to become a “meaningful contributor to revenue and earnings” over time as it capitalizes on the needs of China’s aging and increasingly affluent population.46

These two acquisitions are not merely opportunistic; they represent a fundamental shift in the company’s business mix. They strategically de-risk the enterprise from its heavy concentration in the mature, catastrophe-exposed U.S. P&C market and align it with the powerful secular trend of wealth creation and rising insurance demand in Asia. This is a long-term strategy designed to build a more resilient and faster-growing global enterprise.

C. Management & Capital Allocation

Chubb is led by its long-tenured Chairman and CEO, Evan Greenberg, who is widely regarded as one of the most skilled operators and capital allocators in the insurance industry. The management team has a strong track record of disciplined execution and creating shareholder value.

The company’s approach to capital allocation is balanced and shareholder-friendly. This is funded by the very strong operating cash flow the business generates, which reached a record $15.9 billion in 2024.9 Capital is deployed across three main priorities: investing in organic growth, funding strategic M&A, and returning excess capital to shareholders.

Chubb has a long and consistent history of shareholder returns. In May 2025, the company’s shareholders approved the 32nd consecutive annual increase to its dividend, a hallmark of a stable, cash-generative business.48 In addition to the dividend, the company maintains a significant and active share repurchase program. For example, during the second quarter of 2025, Chubb returned $1.1 billion to shareholders, consisting of $388 million in dividends and $676 million in share repurchases.49 This disciplined and consistent approach to capital allocation is a key component of the company’s long-term value creation model.

VI. Risk Assessment & Headwinds (2022-2024)

A. Catastrophe & Climate Risk

As a leading global property insurer, Chubb has significant exposure to losses from natural catastrophes such as hurricanes, wildfires, and severe convective storms. The insurance industry has faced a challenging environment in recent years, with global insured catastrophe losses exceeding $100 billion for four consecutive years, well above the long-term average.4 This trend, which is influenced by climate change and increased urbanization in high-risk areas, represents a material risk to underwriting profitability.

Chubb is proactively addressing the challenge of climate risk through a dual strategy. First, it has launched Chubb Resilience Services, a consulting-style offering that utilizes cutting-edge climate models and the company’s extensive risk engineering expertise to help clients assess, quantify, and mitigate their exposure to physical climate risks.50 Second, it has established

Chubb Climate+, a dedicated underwriting unit focused on providing insurance solutions for businesses engaged in the transition to a low-carbon economy, such as renewable energy, alternative fuels, and carbon capture technologies.51

This approach is notable because it seeks to monetize the company’s risk management expertise. The primary benefit is improved underwriting of its own portfolio by better understanding and pricing climate-related risks. However, it also creates a new, non-correlated revenue stream from its fee-based risk engineering and consulting services. By helping clients become more resilient to climate events, Chubb can also theoretically lower their future claims costs, creating a mutually beneficial relationship that reinforces its position as a strategic risk partner rather than a simple provider of insurance capacity.

B. Macroeconomic Sensitivities

Chubb’s business is sensitive to broader macroeconomic conditions, particularly inflation and the potential for economic recession.

  • Inflation: The period of high inflation from 2021 to 2022 had a direct and significant impact on claims severity. Rising costs for labor and materials drove up the expense of repairing or replacing damaged property. For example, from May 2021 to May 2022, building material prices increased by 36%.53 In the auto insurance segment, supply chain shortages led to a 41% increase in used car prices from 2019 to 2021, substantially increasing the cost of vehicle replacement claims.53 While Chubb’s disciplined pricing actions have helped to offset these trends, a resurgence of high inflation would remain a headwind to underwriting margins.
  • Recession Resilience: An economic recession could negatively impact premium growth as business activity slows and customers seek to reduce expenses. However, Chubb’s business model has several resilient characteristics. A large portion of its P&C insurance products are non-discretionary purchases for businesses and individuals. Its diversified business mix across numerous product lines and geographies, along with its strong balance sheet, provides a degree of insulation from a downturn in any single economy.54
  • Interest Rates: The interest rate environment presents a dual impact. As discussed, higher rates are a significant benefit to the investment portfolio. However, rapid increases in rates can cause mark-to-market unrealized losses on the existing fixed-income portfolio, which negatively impacts reported book value through Accumulated Other Comprehensive Income (AOCI).

C. Emerging Risks: The Cyber Market

The market for cyber insurance is one of the fastest-growing segments of the P&C industry, but it also presents one of the most complex and evolving risks. Chubb has strategically positioned itself as the leader in the U.S. cyber insurance market.14

This leadership position is both a significant opportunity and a material risk. The growth potential is substantial as businesses of all sizes increasingly recognize the need for protection against cyber threats. Chubb leverages its extensive experience, having handled over 23,000 cyber claims, to inform its underwriting.55 It makes this data-driven insight available to clients through its proprietary

Chubb Cyber Index®, reinforcing its expertise and value proposition.56

The primary risk in this segment is the potential for a systemic cyber event, such as a widespread cloud service provider outage or a novel attack that affects a large number of policyholders simultaneously. The aggregation of risk in the cyber domain is difficult to model and could lead to very large losses. While Chubb’s leadership position provides it with a prime opportunity to shape and profitably grow in this market, it also concentrates its exposure to these potential large-scale loss events.

VII. Valuation Analysis

A. Multiple-Based Valuation

An analysis of Chubb’s valuation using standard multiples provides context on how the market is pricing the company relative to its own history and its peers.

  • Price-to-Earnings (P/E) Ratio: As of August 2025, Chubb’s trailing twelve-month (TTM) P/E ratio is approximately 12.0x to 12.6x.39 Over the past decade, this multiple has fluctuated, generally ranging from a low near 10x to a high approaching 20x.39 The current valuation sits comfortably within the lower-to-middle portion of this historical range, suggesting that the stock is not trading at an unusually expensive level based on its recent earnings.
  • Price-to-Book (P/B) Ratio: The P/B ratio as of August 2025 is approximately 1.6x.33 This is somewhat elevated compared to its historical average, which has often been in the 1.1x to 1.4x range.33 This higher multiple likely reflects the market’s recognition of the company’s improved profitability, as evidenced by its higher return on equity (ROE) in recent years. Compared to peers, Chubb’s P/B of ~1.6x is below that of Travelers (~2.1x) but significantly above that of AIG (~1.1x).59
  • Price-to-Tangible Book Value (P/TBV) Ratio: For a company like Chubb that grows significantly through acquisitions, the P/TBV ratio is a critical metric as it excludes the goodwill and intangible assets recorded during these transactions. As of the second quarter of 2025, Chubb’s tangible book value per share was $112.64.37 This results in a P/TBV ratio of approximately 2.4x. This is comparable to Travelers’ P/TBV of 2.43x but considerably higher than AIG’s, which trades at approximately 1.3x its year-end 2024 tangible book value per share of $63.98.29 This suggests the market values the tangible equity of Chubb and Travelers at a significant premium to that of AIG, likely reflecting their superior returns on that equity.

B. Shareholder Return Profile

Chubb’s capital return policy is a key component of its shareholder value proposition, characterized by a reliable and growing dividend.

  • Dividend Yield and Sustainability: The company’s forward dividend yield is approximately 1.4%.60 While this yield is modest, its sustainability and potential for growth are exceptionally high. This is evidenced by a very low dividend payout ratio of approximately 16% of earnings.60 This low ratio indicates that the current dividend is well-covered by earnings and provides substantial capacity for future increases, as well as for the reinvestment of capital into growth initiatives.
  • Dividend Growth History: The company has an exceptional track record of dividend growth. In May 2025, shareholders approved the 32nd consecutive annual dividend increase, placing Chubb in a select group of companies with such a long history of consistent dividend growth.48 This track record underscores the stability of the company’s cash flow generation and management’s long-standing commitment to returning capital to shareholders.

C. Asset-Based Perspective

An asset-based view of valuation focuses on the quality and value of the company’s balance sheet. The quality of Chubb’s book value appears high, supported by two key factors: a conservative reserving philosophy and a high-quality investment portfolio. Management has publicly stated that the company’s loss reserves—its liability for future claims payments—are as “strong as I can remember”.26 Conservative reserving is a hallmark of disciplined underwriting and reduces the risk of future adverse earnings surprises.

The primary “hidden” asset on the balance sheet may be the embedded earnings power within the investment portfolio. Due to the lag effect of reinvesting cash flows at higher rates, the portfolio’s future income generation potential is likely greater than what is reflected in its current reported yield. Conversely, the primary risk to reported book value is the mark-to-market impact of interest rate fluctuations on the bond portfolio, which is captured in AOCI. However, tangible book value is less susceptible to these fluctuations, providing a more stable measure of the company’s core equity base.
