Evan G. Greenberg, Chairman and Chief Executive Officer of Chubb Limited, commented: “Chubb had an excellent fourth quarter finish to the year, highlighted by very strong earnings, resulting from continued underwriting margin improvement and double-digit commercial lines premium growth globally. Core operating income per share of $3.18 was up nearly 40% with net income per share a record. Our P&C underwriting income was up 82%, with a published combined ratio of 87.6% compared to 92.7% prior year. The margin improvement in our combined ratio was a result of both expense and loss ratio improvements that were broad based. Virtually all of our commercial P&C lines of business are achieving rates that exceed loss costs.

“In the quarter, Global P&C premium revenue, which excludes agriculture, grew 6%. Commercial lines grew over 11% as we capitalized on a strong and continuously improving pricing environment in most regions of the world. In fact, the pricing environment was the strongest we’ve seen since rates in certain classes began to rise about three years ago. Commercial rate increases averaged 16.5% and 18.5%, respectively, in our North America and international businesses. I expect the favorable underwriting conditions to continue. On the other hand, net premiums declined 3.9% in our consumer lines businesses globally, which have been impacted by the pandemic’s effects on consumer activity, but will improve as the year progresses. The one exception of note is our U.S. high net worth personal lines business, which grew in the quarter and the year – a testament to our market-leading franchise.

“For the year, we produced $3.3 billion of core operating income, published a P&C combined ratio of 96.1%, achieved premium revenue growth of 5.4% in constant dollars, with commercial lines growth of 9.3%, and grew tangible book value per share 12.2% – reasonably good results overall given the remarkable and unprecedented events we all faced.

“We are off to a good start in ‘21 with both growth and the level of commercial P&C rate increases resembling the underwriting conditions of the fourth quarter. With our leadership energized and our people focused, and given our full range of capabilities to bring to bear for our clients and business partners, we are confident in our ability to continue growing revenue and expanding underwriting margins.”

Chubb Limited News Release

Regulation G - Non-GAAP Financial Measures

In presenting our results, we included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important for an understanding of our overall results of operations and financial condition. However, they should not be viewed as a substitute for measures determined in accordance with generally accepted accounting principles (GAAP).

Throughout this document there are various measures presented on a constant-dollar basis (i.e., excludes the impact of foreign exchange). We believe it is useful to evaluate the trends in our results exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which our international business is transacted, as these exchange rates could fluctuate significantly between periods and distort the analysis of trends. The impact is determined by assuming constant foreign exchange rates between periods by translating prior period results using the same local currency exchange rates as the comparable current period.

Adjusted net investment income is net investment income excluding the amortization of the fair value adjustment on acquired invested assets from the acquisition of The Chubb Corporation (Chubb Corp) of $26 million in Q4 2020 and $116 million for full-year 2020 and including investment income of $51 million in Q4 2020 and $115 million for full-year 2020 from partially owned investment companies (private equity partnerships) where our ownership interest is in excess of three percent that are accounted for under the equity method. The mark-to-market movement on these private equity partnerships are included in adjusted net realized gains (losses) as described below. We believe this measure is meaningful as it highlights the underlying performance of our invested assets and portfolio management in support of our lines of business.

Adjusted net realized gains (losses), net of tax, includes net realized gains (losses) and net realized gains (losses) recorded in other income (expense) related to unconsolidated subsidiaries, and excludes realized gains and losses on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing impacts underwriting results. We view gains and losses on these derivatives as part of the results of our underwriting operations, and therefore realized gains (losses) from these derivatives are reclassified to adjusted losses and loss expenses.

P&C underwriting income is calculated by subtracting adjusted losses and loss expenses, policy acquisition costs and administrative expenses from net premiums earned by our P&C operations. We use P&C underwriting income and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other income (expense), interest expense, amortization expense of purchased intangibles, Chubb integration expenses, income tax expense and adjusted net realized gains (losses).

Current accident year underwriting income excluding catastrophe losses is underwriting income adjusted to exclude catastrophe losses and prior period development (PPD). We believe it is useful to exclude catastrophe losses, as they are not predictable as to timing and amount, and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business.

Core operating income, net of tax, excludes from net income the after-tax impact of adjusted net realized gains (losses), Chubb integration expenses, and the amortization of fair value adjustment of acquired invested assets and long-term debt related to the Chubb Corp acquisition. We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude adjusted net realized gains (losses) because the amount of these gains (losses) are heavily influenced by, and fluctuate in part according to, the availability of market opportunities. We exclude the amortization of the fair value adjustments related to purchased

Chubb Limited News Release

invested assets and long-term debt and Chubb integration expenses due to the size and complexity of this acquisition. These integration expenses are distortive to our results and are not indicative of our underlying profitability. We believe that excluding these integration expenses facilitates the comparison of our financial results to our historical operating results. References to core operating income measures mean net of tax, whether or not noted.

Core operating return on equity (ROE) and Core operating return on tangible equity (ROTE) are annualized non-GAAP financial measures. The numerator includes core operating income (loss), net of tax. The denominator includes the average shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. For the ROTE calculation, the denominator is also adjusted to exclude goodwill and other intangible assets, net of tax. These measures enhances the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity and tangible equity excluding the effect of unrealized gains and losses on our investments.

P&C combined ratio is the sum of the loss and loss expense ratio, acquisition cost ratio and the administrative expense ratio excluding the life business and including the realized gains and losses on the crop derivatives, as noted above.

Current accident year combined ratio excluding catastrophe losses excludes the impact of catastrophe losses and PPD from the combined ratio. We believe this measure provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our property and casualty business that may be obscured by these items.

Global P&C performance metrics comprise consolidated operating results (including corporate) and exclude the operating results of the company’s Life Insurance and North America Agricultural Insurance segments. The agriculture insurance business is a different business in that it is a public sector and private sector partnership in which insurance rates, premium growth, and risk-sharing is not market-driven like the remainder of the company’s P&C insurance business. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’s global P&C operations which are the most economically similar. We exclude the North America Agricultural Insurance and Life Insurance segments because the results of these businesses do not always correlate with the results of our global P&C operations.

Tangible book value per common share is shareholders’ equity less goodwill and other intangible assets, net of tax, divided by the shares outstanding. We believe that goodwill and other intangible assets are not indicative of our underlying insurance results or trends and make book value comparisons to less acquisitive peer companies less meaningful.

See the reconciliation of Non-GAAP Financial Measures on pages 29-35 in the Financial Supplement. These measures should not be viewed as a substitute for measures determined in accordance with GAAP, including premium, net income, return on equity, and net investment income.

* While there was no change to the previously reported aggregate P&C COVID-19 incurred loss charge from June 30, 2020, there was a reallocation of losses between divisions resulting in a decrease of 1.4 percentage points to the loss ratio for North America Commercial P&C Insurance and an increase of 2.0 percentage points to the loss ratio for Overseas General Insurance.

(1) Full year 2020 net premiums written were adversely impacted by COVID-19 including $160 million recorded in Q2 2020 of exposure adjustments on in-force policies.

(2) Major Accounts & Specialty: large corporate accounts and wholesale business. Commercial: principally middle market and small commercial accounts. Certain 2019 businesses, previously reported within Commercial, are now reported within Major Accounts & Specialty to align with 2020 reporting. The reclassifications are immaterial and have no impact to total reported North America Commercial P&C Insurance segment net premiums written.

Non-GAAP Financial Measures

(Unaudited)

Regulation G—Non-GAAP Financial Measures

In presenting our results, we included and discussed certain non-GAAP measures. These non-GAAP measures, which may be defined differently by other companies, are important for an understanding of our overall results of operations and financial condition. However, they should not be viewed as a substitute for measures determined in accordance with generally accepted accounting principles (GAAP).

Throughout this document there are various measures presented on a constant-dollar basis (i.e., excludes the impact of foreign exchange). We believe it is useful to evaluate the trends in our results exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the currencies in which our international business is transacted, as these exchange rates could fluctuate significantly between periods and distort the analysis of trends. The impact is determined by assuming constant foreign exchange rates between periods by translating prior period results using the same local currency exchange rates as the comparable current period.

Underwriting income (loss) is calculated by subtracting adjusted losses and loss expenses, adjusted policy benefits, policy acquisition costs and administrative expenses from net premiums earned. We use underwriting income (loss) and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other income (expense), interest expense, amortization expense of purchased intangibles, Chubb integration expense, income tax expense and adjusted net realized gains (losses).

CAY underwriting income excluding catastrophe losses (Cats) is underwriting income (loss) adjusted to exclude Cats and prior period development (PPD). We believe it is useful to exclude Cats, as they are not predictable as to timing and amount, and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business.

Adjusted losses and loss expenses include realized gains and losses on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing impacts underwriting results. We view gains and losses on these derivatives as part of the results of our underwriting operations, and therefore realized gains (losses) from these derivatives are reclassified to adjusted losses and loss expenses.

Adjusted policy benefits includes gains and losses from fair value changes in separate account assets, as well as the offsetting movement in separate account liabilities, for purposes of reporting Life Insurance underwriting income. The gains and losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP have been reclassified from Other (income) expense. We view gains and losses from fair value changes in both separate account assets and liabilities as part of the results of our underwriting operations, and therefore these gains and losses are reclassified to adjusted policy benefits.

Adjusted net investment income is net investment income excluding the amortization of the fair value adjustment on acquired invested assets from the acquisition of The Chubb Corporation (Chubb Corp) and including investment income from partially-owned investment companies (private equity partnerships) where our ownership interest is in excess of three percent that are accounted for under the equity method. The mark-to-market movement on these private equity partnerships are included in adjusted net realized gains (losses) as described below. We believe this measure is meaningful as it highlights the underlying performance of our invested assets and portfolio management in support of our lines of business.

Adjusted net realized gains (losses), net of tax, includes net realized gains (losses) and net realized gains (losses) recorded in other income (expense) related to unconsolidated subsidiaries, and excludes realized gains and losses on crop derivatives.

Adjusted interest expense is interest expense excluding the amortization of the fair value adjustment on acquired long-term debt, related to the Chubb Corp acquisition due to the size and complexity of this acquisition.

Other income (expense)—operating excludes from consolidated Other income (expense) the portion of net realized gains and losses related to unconsolidated entities, other income (expense) from private equity partnerships, and gains and losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP. Net realized gains (losses) related to unconsolidated entities is excluded from core operating income (loss) in order to enhance the understanding of our results of underwriting operations as they are heavily influenced by, and fluctuate in part according to, market conditions. Other income (expense) from private equity partnerships and net realized gains and losses related to unconsolidated entities are recorded to Other income (expense) in our income statement on a GAAP basis.

P&C underwriting income and P&C combined ratio exclude the Life Insurance segment. P&C loss and loss expense ratio and P&C combined ratio include adjusted losses and loss expenses in the ratio numerator. P&C expense ratio and P&C combined ratio include policy acquisition costs and administrative expenses in the ratio numerator. A reconciliation of combined ratio to P&C combined ratio is provided on pages 32-35.

CAY P&C combined ratio excluding catastrophe losses excludes Cats and PPD from the P&C combined ratio. We exclude Cats as they are not predictable as to timing and amount and PPD as these unexpected loss developments on historical reserves are not indicative of our current underwriting performance. The combined ratio numerator is adjusted to exclude Cats, net premiums earned adjustments on PPD, prior period expense adjustments and reinstatement premiums on PPD, and the denominator is adjusted to exclude net premiums earned adjustments on PPD and reinstatement premiums on Cats and PPD. In periods where there are adjustments on loss sensitive policies, these adjustments are excluded from PPD and net premiums earned when calculating the ratios. We believe this measure provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our P&C business that may be obscured by these items. This measure is commonly reported among our peer companies and allows for a better comparison.

Expense ratio excluding accident and health (A&H) excludes the impact of our A&H business from our expense ratio. The expense ratio for the A&H business is typically higher than our traditional P&C business, and we believe that this measure provides better comparison to our peer companies that may not have a significant A&H block of business.

Global P&C performance metrics comprise consolidated operating results (including corporate) and exclude the operating results of the company’s Life Insurance and North America Agricultural Insurance segments. The agriculture insurance business is a different business in that it is a public sector and private sector partnership in which insurance rates, premium growth, and risk-sharing is not market-driven like the remainder of the company’s P&C insurance business. We believe that these measures are useful and meaningful to investors as they are used by management to assess the company’s global P&C operations which are the most economically similar. We exclude the North America Agricultural Insurance and Life Insurance segments because the results of these businesses do not always correlate with the results of our global P&C operations.

Core operating income (loss), net of tax, excludes from net income, the after-tax impact of adjusted net realized gains (losses), Chubb integration expenses, and the amortization of fair value adjustment of acquired invested assets and long-term debt related to the Chubb Corp acquisition. We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude adjusted net realized gains (losses) because the amount of these gains (losses) are heavily influenced by, and fluctuate in part according to the availability of market opportunities. We exclude the amortization of the fair value adjustments related to purchased invested assets and long-term debt and Chubb integration expenses due to the size and complexity of this acquisition. These integration expenses are distortive to our results and are not indicative of our underlying profitability. We believe that excluding these integration expenses facilitates the comparison of our financial results to our historical operating results. References to core operating income measures mean net of tax, whether or not noted.

Core operating effective tax rate is income tax expense (benefit) excluding tax expense (benefit) on adjusted net realized gains (losses), tax benefit on amortization of fair value of acquired invested assets and debt, and tax benefit on Chubb integration expenses, divided by income excluding adjusted net realized gains (losses) before tax, amortization of fair value of acquired invested assets and debt before tax, and Chubb integration expenses before tax. We believe the use of this measure is meaningful to show the tax on the underlying performance of our insurance business, by excluding the tax on adjusted net realized gains (losses), the tax on amortization of the fair value adjustments related to purchased invested assets and long-term debt and the tax on Chubb integration expenses. Refer to the definition of core operating income (loss), net of tax above for more information on these adjustments.

Book value per common share, is shareholders’ equity divided by the shares outstanding. Tangible book value per common share, is shareholders’ equity less goodwill and other intangible assets, net of tax, divided by the shares outstanding. We believe that goodwill and other intangible assets are not indicative of our underlying insurance results or trends and make book value comparisons to less acquisitive peer companies less meaningful. Book value per common share excluding mark-to-market, excludes unrealized investment gains (losses). Tangible book value per common share excluding mark-to-market, excludes goodwill and other intangible assets, net of tax, as well as unrealized investment gains (losses), net of tax. We exclude unrealized investment gains (losses) because the amount of these gains (losses) is heavily influenced by changes in market conditions, including interest rate changes, and we believe that excluding these gains and losses would highlight the underlying growth in book value and tangible book value.

International life insurance net premiums written and deposits collected includes deposits collected on universal life and investment contracts (life deposits). Life deposits are not reflected as revenues in our consolidated statements of operations in accordance with GAAP. However, we include life deposits in presenting growth in our life insurance business because new life deposits are an important component of production and key to our efforts to grow our business.

Core operating ROE

Core operating return on equity (ROE) and Core operating return on tangible equity (ROTE) are annualized non-GAAP financial measures. The numerator includes core operating income (loss), net of tax. The denominator includes the average shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. For the ROTE calculation, the denominator is also adjusted to exclude goodwill and other intangible assets, net of tax.

P&C combined ratio

The P&C combined ratio includes the impact of realized gains and losses on crop derivatives. These derivatives were purchased to provide economic benefit, in a manner similar to reinsurance protection, in the event that a significant decline in commodity pricing will impact underwriting results. We view gains and losses on these derivatives as part of the results of our underwriting operations.

The following tables present the calculation of combined ratio, as reported, for each segment to P&C combined ratio, adjusted for catastrophe losses (Cats) and prior period development (PPD).

Chubb Limited

Glossary

Chubb Limited Consolidated comprises all segments including Corporate.

P&C combined ratio: The sum of the loss and loss expense ratio, policy acquisition cost ratio and the administrative expense ratio excluding the life business and including the realized gains and losses on the crop derivatives.

Book value per common share: Shareholders’ equity divided by the shares outstanding.

Tangible book value per common share: Shareholders’ equity less goodwill and other intangible assets, net of tax, divided by the shares outstanding.

Average market yield of fixed maturities: Weighted average yield to maturity of our fixed income portfolio based on the market prices of the holdings as of that date.

Average yield on invested assets: Adjusted net investment income divided by average cost of fixed maturities and other investments, and average market value of equity securities.

Total capitalization: The sum of the short-term debt, long-term debt, trust preferreds, and shareholders’ equity.

Chubb integration expenses: Chubb integration expenses comprise legal and professional fees and all other costs directly related to the integration activities of the Chubb Corp acquisition. Chubb integration expenses are incurred by the overall company and are therefore included in Corporate. These costs are not related to the on-going business activities of the segments and are therefore excluded from our definition of segment income.

Catastrophe losses (Cats): We generally define catastrophe loss events consistent with the definition of the Property Claims Service (PCS) for events in the U.S. and Canada. PCS defines a catastrophe as an event that causes damage of $25 million or more in insured losses and affects a significant number of insureds, including from pandemics such as COVID-19. For events outside of the U.S. and Canada, we generally use a similar definition. Catastrophe loss events are events that occurred in the current calendar year only. Changes in catastrophe loss estimates in the current calendar year that relate to loss events that occurred in previous calendar years are considered prior period development.

Prior period development (PPD) arises from changes to loss estimates recognized in the current year that relate to loss events that occurred in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years.

Reinstatement premiums are additional premiums paid on certain reinsurance agreements in order to reinstate coverage that had been exhausted by loss occurrences. The reinstatement premium amount is typically a pro rata portion of the original ceded premium paid based on how much of the reinsurance limit had been exhausted.

Net premiums earned adjustments within prior period development are adjustments to the initial premium earned on retrospectively rated policies based on actual claim experience that develops after the policy period ends. The premium adjustments correlate to the prior period loss development on these same policies and are fully earned in the period the adjustments are recorded.

Prior period expense adjustments typically relate to either profit commission reserves or policyholder dividend reserves based on actual claim experience that develops after the policy period ends. The expense adjustments correlate to the prior period loss development on these same policies.

Segment income (loss) includes underwriting income (loss), adjusted net investment income, other income (expense) – operating, and amortization expense of purchased intangibles.

Commercial P&C lines includes Commercial P&C, Agriculture and Reinsurance lines of business.

Consumer P&C lines includes Personal and Global accident and health (A&H) lines of business.

NM: Not meaningful.
