(2) New Issued Applications: Item counts of automobiles or homeowners insurance applications for insurance policies that were issued during the period, regardless of whether the customer was previously insured by another Allstate Protection brand. Allstate brand includes automobiles added by existing customers when they exceed the number allowed (currently 10) on a policy. (3) Average Premium - Gross Written: Gross premiums written divided by issued item count. Gross premiums written include the impacts from discounts, surcharges and ceded reinsurance premiums and exclude the impacts from mid-term premium adjustments and premium refund accruals. Average premiums represent the appropriate policy term for each line, which is 6 months for auto and 12 months for homeowners. (4) Average Premium - Net Earned: Earned premium divided by average policies in force for the period. Earned premium includes the impacts from mid-term premium adjustments and ceded reinsurance, but does not include impacts of premium refund accruals. Average premiums represent the appropriate policy term for each line, which is 6 months for auto and 12 months for homeowners. (5) Calculated by annualizing net earned premium reported in the quarter and year-to-date divided by policies in force at quarter end. (6) Average underlying loss (incurred pure premium) and expense is calculated as the underlying combined ratio multiplied by the annualized average premium. (7) Renewal ratio: Renewal policies issued during the period, based on contract effective dates, divided by the total policies issued 6 months prior for auto or 12 months prior for homeowners. (8) Paid claim frequency is calculated as annualized notice counts closed with payment in the period divided by the average of policies in force with the applicable coverage during the period. Gross claim frequency is calculated as annualized notice counts received in the period divided by the average of policies in force with the applicable coverage during the period. Gross claim frequency includes all actual notice counts, regardless of their current status (open or closed) or their ultimate disposition (closed with a payment or closed without payment). Frequency statistics exclude counts associated with catastrophe events. The percent change in paid or gross claim frequency is calculated as the amount of increase or decrease in the paid or gross claim frequency in the current period compared to the same period in the prior year; divided by the prior year paid or gross claim frequency. (9) Paid claim severity is calculated by dividing the sum of paid losses and loss expenses by claims closed with a payment during the period. The percent change in paid claim severity is calculated as the amount of increase or decrease in paid claim severity in the current period compared to the same period in the prior year; divided by the prior year paid claims severity.

The IRR represents the rate of return on the investments considering the cash flows paid and received and, until the investment is fully liquidated, the estimated value of investment holdings at the end of the measurement period. The calculated IRR for any measurement period is highly influenced by the values of the portfolio at the beginning and end of the period, which reflect the estimated fair values of the investments as of such dates. As a result, the IRR can vary significantly for different measurement periods based on macroeconomic or other events that impact the estimated beginning or ending portfolio value, such as the global financial crisis. Our IRR calculation method may differ from those used by other investors. The timing of the recognition of income in the financial statements may differ significantly from the cash distributions and changes in the value of these investments.

Definitions of Non-GAAP Measures We believe that investors’ understanding of Allstate’s performance is enhanced by our disclosure of the following non-GAAP measures. Our methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited. Adjusted net income is net income applicable to common shareholders, excluding: • realized capital gains and losses, after-tax, except for periodic settlements and accruals on non-hedge derivative instruments, which are reported with realized capital gains and losses but included in adjusted net income, • valuation changes on embedded derivatives not hedged, after-tax, • amortization of deferred policy acquisition costs ("DAC") and deferred sales inducements (“DSI”), to the extent they resulted from the recognition of certain realized capital gains and losses or valuation changes on embedded derivatives not hedged, after-tax, • business combination expenses and the amortization of purchased intangible assets, after-tax, • gain (loss) on disposition of operations, after-tax, and • adjustments for other significant non-recurring, infrequent or unusual items, when (a) the nature of the charge or gain is such that it is reasonably unlikely to recur within two years, or (b) there has been no similar charge or gain within the prior two years. Net income applicable to common shareholders is the GAAP measure that is most directly comparable to adjusted net income. We use adjusted net income as an important measure to evaluate our results of operations. We believe that the measure provides investors with a valuable measure of the Company's ongoing performance because it reveals trends in our insurance and financial service business that may be obscured by the net effect of realized capital gains and losses, valuation changes on embedded derivatives not hedged, business combination expenses and the amortization of purchased intangible assets, gain (loss) on disposition of operations and adjustments for other significant non-recurring, infrequent or unusual items. Realized capital gains and losses, valuation changes on embedded derivatives not hedged and gain (loss) on disposition of operations may vary significantly between periods and are generally driven by business decisions and external economic developments such as capital market conditions, the timing of which is unrelated to the insurance underwriting process. Consistent with our intent to protect results or earn additional income, adjusted net income includes periodic settlements and accruals on certain derivative instruments that are reported in realized capital gains and losses because they do not qualify for hedge accounting or are not designated as hedges for accounting purposes. These instruments are used for economic hedges and to replicate fixed income securities, and by including them in adjusted net income, we are appropriately reflecting their trends in our performance and in a manner consistent with the economically hedged investments, product attributes (e.g. net investment income and interest credited to contractholder funds) or replicated investments. Business combination expenses are excluded because they are non-recurring in nature and the amortization of purchased intangible assets is excluded because it relates to the acquisition purchase price and is not indicative of our underlying insurance business results or trends. Non-recurring items are excluded because, by their nature, they are not indicative of our business or economic trends. Accordingly, adjusted net income excludes the effect of items that tend to be highly variable from period to period and highlights the results from ongoing operations and the underlying profitability of our business. A byproduct of excluding these items to determine adjusted net income is the transparency and understanding of their significance to net income variability and profitability while recognizing these or similar items may recur in subsequent periods. Adjusted net income is used by management along with the other components of net income applicable to common shareholders to assess our performance. We use adjusted measures of adjusted net income in incentive compensation. Therefore, we believe it is useful for investors to evaluate net income applicable to common shareholders, adjusted net income and their components separately and in the aggregate when reviewing and evaluating our performance. We note that investors, financial analysts, financial and business media organizations and rating agencies utilize adjusted net income results in their evaluation of our and our industry's financial performance and in their investment decisions, recommendations and communications as it represents a reliable, representative and consistent measurement of the industry and the Company and management's performance. We note that the price to earnings multiple commonly used by insurance investors as a forward-looking valuation technique uses adjusted net income as the denominator. Adjusted net income should not be considered a substitute for net income applicable to common shareholders and does not reflect the overall profitability of our business. A reconciliation of adjusted net income to net income applicable to common shareholders is provided in the schedule, "Contribution to Income". Combined ratio excluding the effect of catastrophes, prior year reserve reestimates and the amortization of purchased intangible assets ("underlying combined ratio") is a non-GAAP ratio, which is computed as the difference between four GAAP operating ratios: the combined ratio, the effect of catastrophes on the combined ratio, the effect of prior year non-catastrophe reserve reestimates on the combined ratio, the effect of amortization of purchased intangible assets on the combined ratio. We believe that this ratio is useful to investors and it is used by management to reveal the trends in our Property-Liability business that may be obscured by catastrophe losses, prior year reserve reestimates, amortization of purchased intangible assets. Catastrophe losses cause our loss trends to vary significantly between periods as a result of their incidence of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year reserve reestimates are caused by unexpected loss development on historical reserves. Amortization of purchased intangible assets relates to the acquisition purchase price and is not indicative of our underlying insurance business results or trends. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. We also provide it to facilitate a comparison to our outlook on the underlying combined ratio. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered a substitute for the combined ratio and does not reflect the overall underwriting profitability of our business. A reconciliation of the underlying combined ratio to combined ratio is provided in the schedules "Property-Liability Results", "Allstate Brand Profitability Measures", "Esurance Brand Profitability Measures and Statistics", "Encompass Brand Profitability Measures and Statistics", "Auto Profitability Measures by Brand", "Homeowners Profitability Measures by Brand", "Other Personal Lines Profitability Measures by Brand" and "Commercial Lines Profitability Measures". Average underlying loss (incurred pure premium) and expense is calculated as the underlying combined ratio (a non-GAAP measure) multiplied by the GAAP quarterly earned premium, which is annualized (multiplied by 4) (“average premium”). We believe that this measure is useful to investors and it is used by management for the same reasons noted above for the underlying combined ratio. A reconciliation of average underlying loss and expense is provided in the schedule, "Allstate Brand Statistics". The Allstate Corporation 2Q18 Supplement 56

Definitions of Non-GAAP Measures (continued) Underlying loss ratio is a non-GAAP ratio, which is computed as the difference between three GAAP operating ratios: the loss ratio, the effect of catastrophes on the combined ratio and the effect of prior year non-catastrophe reserve reestimates on the combined ratio. We believe that this ratio is useful to investors and it is used by management to reveal the trends that may be obscured by catastrophe losses and prior year reserve reestimates. Catastrophe losses cause our loss trends to vary significantly between periods as a result of their incidence of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year reserve reestimates are caused by unexpected loss development on historical reserves. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our underwriting performance. The most directly comparable GAAP measure is the loss ratio. The underlying loss ratio should not be considered a substitute for the loss ratio and does not reflect the overall loss ratio of our business. A reconciliation of underlying loss ratio is provided in the schedules "Property-Liability Results", "Historical Property-Liability Results", "Allstate Brand Profitability Measures", "Esurance Brand Profitability Measures and Statistics", "Encompass Brand Profitability Measures and Statistics", "Auto Profitability Measures by Brand", "Homeowners Profitability Measures by Brand" and "Other Personal Lines Profitability Measures by Brand". Adjusted net income return on common shareholders' equity is a ratio that uses a non-GAAP measure. It is calculated by dividing the rolling 12-month adjusted net income by the average of common shareholders’ equity at the beginning and at the end of the 12-months, after excluding the effect of unrealized net capital gains and losses. Return on common shareholders' equity is the most directly comparable GAAP measure. We use adjusted net income as the numerator for the same reasons we use adjusted net income, as discussed above. We use average common shareholders' equity excluding the effect of unrealized net capital gains and losses for the denominator as a representation of common shareholders’ equity primarily attributable to the Company’s earned and realized business operations because it eliminates the effect of items that are unrealized and vary significantly between periods due to external economic developments such as capital market conditions like changes in equity prices and interest rates, the amount and timing of which are unrelated to the insurance underwriting process. We use it to supplement our evaluation of net income applicable to common shareholders and return on common shareholders' equity because it excludes the effect of items that tend to be highly variable from period to period. We believe that this measure is useful to investors and that it provides a valuable tool for investors when considered along with return on common shareholders' equity because it eliminates the after-tax effects of realized and unrealized net capital gains and losses that can fluctuate significantly from period to period and that are driven by economic developments, the magnitude and timing of which are generally not influenced by management. In addition, it eliminates non-recurring items that are not indicative of our ongoing business or economic trends. A byproduct of excluding the items noted above to determine adjusted net income return on common shareholders' equity from return on common shareholders' equity is the transparency and understanding of their significance to return on common shareholders' equity variability and profitability while recognizing these or similar items may recur in subsequent periods. We use adjusted measures of adjusted net income return on common shareholders' equity in incentive compensation. Therefore, we believe it is useful for investors to have adjusted net income return on common shareholders' equity and return on common shareholders' equity when evaluating our performance. We note that investors, financial analysts, financial and business media organizations and rating agencies utilize adjusted net income return on common shareholders' equity results in their evaluation of our and our industry’s financial performance and in their investment decisions, recommendations and communications as it represents a reliable, representative and consistent measurement of the industry and the company and management’s utilization of capital. Adjusted net income return on common shareholders' equity should not be considered a substitute for return on common shareholders' equity and does not reflect the overall profitability of our business. A reconciliation of return on common shareholders' equity and adjusted net income return on common shareholders' equity can be found in the schedule, "Return on Common Shareholders' Equity". Adjusted net income return on adjusted equity is a ratio that uses a non-GAAP measure. It is calculated by dividing the rolling 12-month adjusted net income by the equity balance, after excluding the effect of unrealized net capital gains and losses and goodwill. Return on equity is the most directly comparable GAAP measure. We use equity excluding the effect of unrealized net capital gains and losses and goodwill for the denominator as a representation of equity primarily attributable to the Company’s earned and realized business operations. Unrealized net capital gains and losses are excluded because they vary significantly between periods due to external economic developments such as capital market conditions like changes in equity prices and interest rates, the amount and timing of which are unrelated to the insurance underwriting process. Goodwill is excluded because it relates to the acquisition purchase price and is not indicative of our underlying business results. We believe it is useful for investors to have adjusted net income return on adjusted equity when evaluating our performance as it represents a reliable, representative and consistent measurement of the company and management’s utilization of capital. Adjusted net income return on adjusted equity should not be considered a substitute for return on equity and does not reflect the overall profitability of our business. A reconciliation of return on equity and adjusted net income return on adjusted equity can be found in the schedules, "Allstate Life Return on Equity", "Allstate Benefits Return on Equity" and "Allstate Annuities Return on Equity". Adjusted net income, excluding purchase accounting adjustments, is a non-GAAP measure, which is computed as net income (loss) applicable to common shareholders, excluding amortization of purchased intangible assets, after- tax, and realized capital gains and losses, after-tax, and adjusted for the after-tax income statement effects of acquisition-related purchase accounting fair value adjustments to unearned premiums, contractual liability insurance policy premium expenses, and commissions paid to retailers. Net income (loss) applicable to shareholders is the GAAP measure that is most directly comparable to adjusted net income, excluding purchase accounting adjustments. We use adjusted net income, excluding purchase accounting adjustments, as an important measure to evaluate SquareTrade’s results of operations. We believe that the measure provides investors with a valuable measure of SquareTrade’s ongoing performance because it reveals trends that may be obscured by the amortization of purchased intangible assets, the acquisition-related purchase accounting fair value adjustments, and the net effects of realized capital gains and losses. Amortization of purchased intangible assets is excluded because it relates to the acquisition purchase price and is not indicative of our business results or trends. We adjust for the effects of acquisition-related purchase accounting fair value adjustments because they relate to the acquisition and their effects are not indicative of the underlying business results and trends. Realized capital gains and losses may vary significantly between periods and are generally driven by business decisions and external economic developments such as capital market conditions, the timing of which is unrelated to SquareTrade’s operations. Adjusted net income, excluding purchase accounting adjustments, highlights the results from ongoing operations and the underlying profitability of our business and is used by management along with the other components of net income applicable to common shareholders to assess our performance. We believe it is useful for investors to evaluate net income applicable to common shareholders, adjusted net income, excluding purchase accounting adjustments, and their components separately and in the aggregate when reviewing and evaluating SquareTrade’s performance. Adjusted net income, excluding purchase accounting adjustments, should not be considered a substitute for net income applicable to common shareholders and does not reflect the overall profitability of our business. A reconciliation of net income (loss) applicable to common shareholders to adjusted net income, excluding purchase accounting adjustments, is provided in the schedule, "SquareTrade Results". Book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, is a ratio that uses a non-GAAP measure.  It is calculated by dividing common shareholders’ equity after excluding the impact of unrealized net capital gains and losses on fixed income securities and related DAC, DSI and life insurance reserves by total common shares outstanding plus dilutive potential common shares outstanding.  We use the trend in book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, in conjunction with book value per common share to identify and analyze the change in net worth attributable to management efforts between periods.  We believe the non-GAAP ratio is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period and are generally driven by economic developments, primarily capital market conditions, the magnitude and timing of which are generally not influenced by management, and we believe it enhances understanding and comparability of performance by highlighting underlying business activity and profitability drivers.  We note that book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, is a measure commonly used by insurance investors as a valuation technique.  Book value per common share is the most directly comparable GAAP measure. Book value per common share, excluding the impact of unrealized net capital gains and losses on fixed income securities, should not be considered a substitute for book value per common share, and does not reflect the recorded net worth of our business.  A reconciliation of book value per common share, excluding the impact of unrealized net capital gains on fixed income securities, and book value per common share can be found in the schedule, "Book Value per Common Share".
