Effective Q4 2017, in consideration of the SEC guidance onnon-GAAP financial measures, the company relabeled operating income, operating return on equity (ROE) and operating effective tax rate to “core operating income”, “core operating ROE”, and “core operating effective tax rate,” respectively. This is a change in terminology only and the method of calculation and definition of these measures is consistent with prior periods.

Non-GAAP Financial Measures

(Unaudited)

Regulation G -Non-GAAP Financial Measures

In presenting our results, we included and discussed certainnon-GAAP measures. Thesenon-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).

We provide financial measures such as gross premiums written, net premiums written, net premiums earned, and core operating income (loss) on a constant-dollar basis. We believe it is useful to evaluate the trends in these measures 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 losses and loss expenses and adjusted administrative expenses arenon-GAAP financial measures that exclude theone-time curtailment benefit related to the harmonization of the company’s U.S. pension plans. During the fourth quarter of 2016, the company harmonized and amended several U.S. retirement programs to create a unified retirement savings program which resulted in theone-time pension curtailment benefit. The portion of the benefit related to claims staff is excluded from adjusted losses and loss expenses with the remainder excluded from adjusted administrative expenses. We believe that excluding the impact of theone-time pension curtailment benefit provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our property & casualty business that may be obscured by this item. Adjusted losses and loss expenses also includes realized gains and losses on crop derivatives. The crop derivatives are 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 and therefore realized gains and losses from these derivatives are reclassified from adjusted net realized gains (losses), also anon-GAAP financial measure.

In presenting our segment income results, we have shown our performance with reference to underwriting results. Underwriting results are calculated by subtracting adjusted losses and loss expenses, policy benefits, policy acquisition costs, and adjusted administrative expenses from net premiums earned. We use underwriting results and adjusted operating ratios to monitor the results of our operations without the impact of certain factors, including investment income, other income and expenses, interest and income tax expense, and adjusted net realized gains (losses). P&C underwriting income is anon-GAAP financial measure which excludes the Life Insurance segment. P&C loss and loss expense ratio and P&C combined ratio (bothnon-GAAP financial measures) include adjusted losses and loss expenses in the ratio numerator. P&C expense ratio (anon-GAAP financial measure) and P&C combined ratio include policy acquisition costs and adjusted administrative expenses in the ratio numerator. A reconciliation of combined ratio to P&C combined ratio is provided on page 34.

P&C combined ratio excluding the impact of catastrophe losses and prior period development (PPD) and the P&C loss and loss expense ratio excluding the impact of catastrophe losses and PPD arenon-GAAP financial measures. The loss ratio numerator includes adjusted losses and loss expenses and excludes catastrophe losses and PPD. The combined ratio numerator includes adjusted losses and loss expenses, policy acquisition costs, and adjusted administrative expenses. The denominator for both ratios includes net premiums earned adjusted to exclude the amount of reinstatement premiums (expensed) collected. In periods where there are adjustments on loss sensitive policies, these adjustments are excluded from PPD and net earned premiums when calculating the ratios. We believe that excluding the impact of catastrophe losses and PPD provides a better evaluation of our underwriting performance and enhances the understanding of the trends in our property & casualty business that may be obscured by these items.

P&C expense ratio excluding accident and health (A&H) is anon-GAAP financial measure and excludes the impact of our A&H business from our P&C 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 arenon-GAAP financial measures and comprise consolidated adjusted operating results (including corporate) and exclude the adjusted operating results of the company’s Life Insurance and North America Agricultural Insurance segments. 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.

Adjusted net investment income is net investment income excluding the amortization of the fair value adjustment of acquired invested assets. Adjusted interest expense is interest expense excluding the amortization of the fair value adjustment of acquired debt and the interest expense on the $5.3 billion senior notes issued in November 2015 until the closing of the Chubb Corp acquisition on January 14, 2016. We believe that excluding these items are meaningful in order to present the underlying economics of the company’s business.

Other income (expense) – operating is anon-GAAP financial measure and excludes the portion of net realized gains and losses related to unconsolidated entities from other income (expense). These gains and losses are reported as net realized gains (losses) and represent thenon-operating activities of entities where we hold more than an insignificant percentage of the investee’s shares. We exclude these gains and losses from other income (expense) to enhance the understanding of our segments’ operations as they are heavily influenced by, and fluctuate in part according to market conditions. Other income (expense) – operating and net realized gains and losses related to unconsolidated entities are recorded to Other income (expense) in our income statement on a GAAP basis.

Core operating income (loss) is anon-GAAP financial measure that excludes theafter-tax impact of adjusted net realized gains (losses), net realized gains (losses) included in other income (expense) related to partially owned entities, Chubb integration and related expenses, and the amortization of the fair value adjustments related to purchased invested assets and long-term debt from the Chubb Corp acquisition. We exclude realized gains and 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 Chubb integration and related expenses due to the size and complexity of this acquisition. These integration and related expenses are distortive to our results and are not indicative of our underlying profitability. We believe that excluding these integration and related expenses facilitates the comparison of our financial results to our historical operating results. Chubb integration expenses are incurred by the overall company and are therefore included in Corporate. The costs are not related to theon-going activities of the individual segments and are therefore excluded from our definition of segment income, as well. We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. Core operating income (loss) should not be viewed as a substitute for net income (loss) determined in accordance with GAAP.

Core operating effective tax rate is anon-GAAP financial measure. The numerator excludes tax on adjusted net realized gains (losses), tax on net realized gains (losses) included in other income (expense) related to partially owned entities, tax on Chubb integration and related expenses, and tax on the amortization of the fair value adjustments related to purchased invested assets and long-term debt from the Chubb Corp acquisition. The denominator excludes these same items, before tax. Core operating effective tax rate should not be viewed as a substitute for effective tax rate determined in accordance with GAAP.

Tangible book value per common share is anon-GAAP financial measure and 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. A reconciliation of tangible book value per share is provided on page 30. In addition, we disclose per share measures that exclude the impact of foreign currency fluctuations during 2016 in order to adjust for the distortive effects of fluctuations in exchange rates.

International life insurance net premiums written and deposits collected, is anon-GAAP financial measure. Deposits collected on universal life and investment contracts (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.

2016 “As If” company measures presented throughout this section are prepared inclusive of the first 14 days of January 2016 prior to the acquisition close and exclusive of the impact of the unearned premium reserves intangible amortization and the elimination of the historical policy acquisition costs as a result of purchase accounting in order to present the underlying profitability of our insurance business. We believe thesenon-GAAP measures provide visibility into our results and trends in our business by allowing for a better assessment and comparability to our historical results. These measures are consistent with how management evaluates results.

Net premiums written excluding merger-related actions is anon-GAAP performance measure. Since the acquisition of The Chubb Corporation, we have entered into new reinsurance agreements with third-party reinsurers for the Chubb Corp businesses and have taken other merger-related underwriting actions, including exiting certain types of business that do not meet our underwriting standards or adhere to our risk diversification strategy. We also exclude a merger-related accounting policy alignment adjustment and aone-time unearned premium reserve (UPR) transfer in 2016. We believe that these measures are meaningful to evaluate trends in our underlying business on a comparable basis.

Core operating ROE

Core operating return on equity (ROE) or ROE calculated using core operating income (loss): The ROE numerator includes income adjusted to excludeafter-tax adjusted net realized gains (losses), Chubb integration and related expenses, and the amortization of the fair value adjustment of acquired invested assets and long-term debt. The ROE denominator includes the average shareholders’ equity for the period adjusted to exclude unrealized gains (losses) on investments, net of tax. In addition, for 2016, the denominator was adjusted to account for the weighted-average impact of the $15,527 million issuance of common shares and equity awards related to The Chubb Corp acquisition on January 14, 2016. Core operating ROE is a useful measure as it enhances the understanding of the return on shareholders’ equity by highlighting the underlying profitability relative to shareholders’ equity excluding the effect of unrealized gains and losses on our investments.

Chubb integration and related expenses, net of tax

Chubb integration and related expenses is anon-GAAP financial measure and includes all internal and external costs directly related to the integration activities of The Chubb Corp acquisition, consisting primarily of personnel-related expenses, including severance and employee retention and relocation; consulting fees; and advisor fees. Chubb integration and related expenses also include interest expense on the $5.3 billion senior notes issued in November 2015. We exclude Chubb integration expenses related to The Chubb Corp acquisition from core operating income (loss) due to the size and complexity of this acquisition. We exclude thepre-acquisition interest expense from core operating income (loss) because the operations for which the debt was issued were not part of our operating activities prior to the completion of the acquisition. Effective with the close of The Chubb Corp acquisition (January 14, 2016), the interest on this debt was considered a cost of our operations and is included within core operating income (loss). These integration and related expenses are distortive to our results and are not indicative of our underlying profitability. We believe that excluding these integration and related expenses facilitate the comparison of our financial results to our historical operating results. The following table presents the reconciliation of Chubb integration expenses on a GAAP basis to Chubb integration and related expenses.

We view gains and losses on these derivatives as part of the results of our underwriting operations.

References to Core operating income excluding normalized Catastrophe losses (Cats) and one-time tax reform benefit, are prepared excluding any impact of the catastrophe losses above normal level due to the significant size and number of these events in the third quarter of 2017 which could obscure the underlying operating results, as well as excluding the one-time 2017 tax reform transition benefit. We believe that these measures provide a better evaluation of our operating performance and enhances the understanding of the trends in our property and casualty business.

The following table presents the reconciliation of Core operating income and Core operating income w/Normalized Catastrophe losses and excluding one-time tax reform benefit:
